More reliable signal handling in Autotest.

job token, so the master process does not hang.
Disable the parallel driver if job control is not provided or if
trap does not understand signal names.

The test suite did not cover this bug because the code was not
quoting properly the arguments of `rm -f' (which "fails" silently)
as well as the arguments of `diff' (whose output was redirected to
/dev/null so we couldn't see its error message).

* tests/tools.at (Syntax of the shell scripts): Likewise.
* tests/m4sh.at (LINENO): Quote $0.
Fix testsuite program wrapper for whitespace in `pwd`.
The problem here is that the usual mantra is that command
variables can contain arguments, thus we cannot just escape
$AUTOCONF, $AUTOM4TE etc. The compromise is to put the
$top_builddir/tests directory early in $PATH, so that the
wrappers are found by their plain name.

Proper file name escaping in Autoconf programs and Perl modules.
This includes escaping of characters special to the shell
as well as special to Perl, e.g., leading `<' or `>'.
For example, when $file starts with `>', `open ">$file"'
wrongly tries to append to a different file.
* bin/autoconf.as: Fix quoting for autom4te options.

2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autotest/general.m4: Revert 2007-11-15 patch and
subsequent fixups; the awk -> here-document conversion trashes
performance too much with AIX sh.
2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* tests/local.at: Do not test m4, perl with AT_TESTED.
Diagnose and guard against write errors dealing with config.status.
The general idea is this: all write failures from `configure'
writing `config.status' are indicated by $ac_write_error, which
is only checked at the end. This is safe because config.status
code is not executed before the file is complete. Other write
failures, be they inside config.status, or in sub shell/awk
scripts spawned from configure or config.status, typically need
earlier checking, as their results are used right afterwards.
* lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
before writing config.status, check afterwards.
(_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
(_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
Set `ac_write_error' for write failures to config.status. Barf
upon write failures to temporary files.
Adjust note about closing and reopening the here-document.
(_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
(_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
reopening the here-document.
* tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
Ensure `ac_write_error' does not escape into config.status.
Also, add a couple of code paths not yet exercised in the test
suite: a config file with input from stdin, and a config header
output to stdout.
Suggestion for catching write errors by Bruno Haible.
2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
Avoid error with Tru64 awk and testsuite lines with many words.
* lib/autotest/general.m4 (AT_INIT): In the awk script that

in order to not run over the limit of 199 fields. Tru64 4.0D awk
even splits the input if $i, i>0, was never accessed in the script.

dependency on distclean-local. Simply adding the dependency would
cause automake not to emit the rule at all.
* BUGS: Building with -jN works, now.
Distribute git-version-gen.

Use it where possible.
Suggestion by Benoit Sigoure.
2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
Adjust the documentation of autotest WRT atlocal.
* doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
when using Automake, to write a rule to produce atlocal, since it's
an AC_CONFIG_FILES. Mention that atlocal.in needs to be
distributed, not atconfig.in.

2007-10-28 Jim Meyering <meyering@redhat.com>
Make inter-release --version output more useful.
Now, each unofficial build has a version "number" like 2.61a-19-58dd,
which indicates that it is built using the 19th change set

is a prefix of the commit SHA1.
* build-aux/git-version-gen: New file.

not configure.ac, now that the version number changes automatically.
Ensure that $(VERSION) is up to date for dist-related targets.
* GNUmakefile: Arrange to rerun autoconf, if the version reported by
git-version-gen doesn't match $(VERSION), but only for dist targets.

escaping of backslash in here-documents.
Fix `Deep Package' test failure on FreeBSD.

this resolution. Fixes test failure on FreeBSD.
Fix config header generation with AIX awk.

Bruno Haible.
2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
for a.* when searching for executables, as this prevents users
from having files like a.c. Problem reported by Ralf Wildenhues in:

* NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
AC_CHECK_TYPE, AC_CHECK_TYPES.
* doc/autoconf.texi (Generic types): C types must be type-names
(the C terminology), not type-ids (the C++ term). C++ types
must not be anonymous.
* lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
for C++; this drops support for anonymous struct and union types,
which were problematic anyway.

with objects too. Document the restrictions on its use.
Document the restrictions on AC_CHECK_ALIGNOF's type argument.
* lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
works but the latter doesn't, then it's a valid type.
This lets people use function types and so forth.
For C++ there doesn't seem to be a simple solution, so leave it alone.
(AC_CHECK_SIZEOF): Allow argument to be a variable.
(AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
AC_CHECK_TYPE; that wasn't documented or necessary.

more pitfalls.
2007-03-23 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
checks for unsigned long long int.
2007-03-19 Paul Eggert <eggert@cs.ucla.edu>

HP-UX's grep, like the one from Solaris, does not support that syntax.
2007-03-09 Stepan Kasal <kasal@ucw.cz>
* doc/autoconf.texi (Specifying Names): `--host' does not
change the build type.

* doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
suggests AC_CONFIG_HEADERS.

2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its

early on the reader side, drop stderr of the input to avoid
`broken pipe' error output; this may happen even with shell
builtin `echo' of some bash versions. Reports by Ian Macdonald

2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
Fix some wording problems noted by Paolo Bonzini in:
http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
* doc/autoconf.texi (Signed Overflow Examples): Give more
discussion about the allow_superuser_privileges example,
and change it a bit to make things clearer.
(Optimization and Wraparound): Clarify whether the compiler
will generate an infinite loop for the example derived from
Autoconf's mktime test.
(Signed Overflow Advice): Say that -ftrapv is meant for debugging.
Also, clarify unsigned multiplication overflow.
2007-01-04 Eric Blake <ebb9@byu.net>

2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Integer Overflow): Revised based on today's
feedback. The most important changes document what happens when
you convert an out-of-range value to a signed integer type, and
say that (sum < a) != (b < 0) reliably detects overflow when sum =
a + b.
* doc/autoconf.texi (Integer Overflow): Greatly expand and
rewrite, taking notions from the recent discussion on the gcc and
autoconf mailing lists; please see
http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html

2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
* lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
preprocessor macro arguments in traced name.
* doc/autoconf.texi (Defining symbols): Document longstanding
support for AC_DEFINE-ing macros with arguments, and document
behavior when the same variable has multiple AC_DEFINEs.
* lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
macros directly, giving much shorter and simpler code.
2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
space before "$ac_configure_args" to prevent a 'config.status
--recheck' failure if ac_configure_args doesn't contain a leading
space. This works around a problem with the XEmacs configure.ac,
which uses the (undocumented) ac_configure_args variable
inconsistently with Autoconf.
2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
Include <limits.h>, and use its INT_MAX to rewrite the
j loop so that it does not overflow 'int'. Problem reported by
Ralf Wildenhues in
<http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
Play it safe by shifting left by 1 rather than multiplying by 2,
as GCC is less likely to optimize this away when the value
is signed (when it assumes overflow leads to undefined behavior).
Also, don't assume time_t uses two's complement.
2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* tests/torture.at (Substitute a 2000-byte string): Avoid using
a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh

--with argument, rather than argument with [-.] replaced by
underscores.
* NEWS: Fix typo in previous change; the news was in the
wrong section.
2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
* NEWS: Warnings are now generated by default for unknown

Don't warn if $enable_option_checking is "no".
* lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
ac_unrecognized_opts to the empty string.
Don't echo the unrecognized opts, as this might mishandle
backslashes or leading -.

usage next to the other --disable-FEATURE options in the
help string.

This change prompted by a problem report by Andrey Simonenko in
<http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.

2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
too drastic, even if Texinfo in theory requires it for info mode.
(config.status Invocation): Renamed back from Recreating a
Configuration).
(Obsolete config.status Use): Renamed back from Obsolete Recreation.
(Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
* NEWS: Version 2.61a.
2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* NEWS: Document changes with echo and printf, and the lack
of limits on the total size of multi-line values of substituted
variables, and the AC_FUNC_FSEEKO fix.
2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Writing Autoconf Input): Renamed from
Writing configure.ac.
(Autoconf Input Layout): Renamed from configure.ac Layout.
(Recreating a Configuration): Renamed from config.status Invocation.
(Obsolete Recreation): Renamed from Obsolete config.status Use.

(Writing Testsuites): Renamed from Writing testsuite.at.
(Autom4te Cache): Renamed from autom4te.cache.
* BUGS: Remove mention of VPATH problem, since it's now documented
not to be a bug in the Autoconf build procedure itself, but rather
a problem with the proprietary `make' programs.
* doc/autoconf.texi (Build Directories): Add a cross reference
to VPATH and Make.
* build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
* doc/standards.texi: Sync from gnulib.
* man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
* man/autoscan.1, man/autoupdate.1, man/config.guess.1:
* man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
generated automatically.
2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
`CEOF$ac_eof' special marker, the awk script cannot contain a
line matching `^CEOF', so this is not needed any more.
* tests/torture.at (Substitute a newline): Expose the `%!_!# '
special marker in the test.
2006-12-06 Stepan Kasal <kasal@ucw.cz>
* tests/tools.at (autom4te preselections): Use `find -newer';
remove one of the sleeps.
* lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
more readable, using ...
(_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
* doc/autoconf.texi (autoheader Invocation): Do not double-
quote the parameter of `AH_BOTTOM' in the example.
2006-12-05 Stepan Kasal <kasal@ucw.cz>
* doc/autoconf.texi (Configuration Headers): Remove the
example with multiple input files.
(autoheader Invocation): Encourage `AH_BOTTOM', discouraging
multiple input files.
2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
creating the awk substitution script, handle one input line at a
time, so that the maximum length of a substituted (multi-line)
value is not limited by the size of the sed pattern space.
The trade-off is a slightly repetitive sed script.
* doc/autoconf.texi (Limitations of Usual Tools): Branch labels
can only have up to 7 characters, due to Solaris 10 /bin/sed.
* tests/torture.at (Substitute a 2000-byte string): Increase the
test with several long lines, they should not be caught by sed
limits any more.
* tests/tools.at (autom4te preselections): New test, to flag
entries missing from autom4te.cfg.
Report by David Byron <dbyron@hheld.com>.
* tests/torture.at (Substitute a 2000-byte string): Actually use
AC_PROG_AWK, so the last change works as intended.
(Substitute and define special characters): Likewise.
(Substitute a newline): Likewise.
* lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
instead of `awk' consistently.
(_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
* tests/torture.at (Torturing config.status): Test both the
result of AC_PROG_AWK and plain awk.
(Substitute a 2000-byte string): Likewise.

Peter Palfrader in <http://bugs.debian.org/401377>. Based on
part of a patch by Ralf Wildenhues in that same bug report.
2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
* tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
* tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
2006-12-01 Eric Blake <ebb9@byu.net>
* lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
cross-compiling from cygwin to mingw.
Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
aclang.m4, which was mistakenly removed in the 2001-09-17 patch
to lib/autoconf/c.m4.
2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
string for more reliable failure. Wrap the entire test that
causes the broken Solaris printf to dump core, in a subshell,
so the segmentation fault message is reliably suppressed.
Fix shell expansion errors by using /usr/ucb/echo always;
avoid an error on systems without it by another subshell.
Avoid m4 expansion of `$1'. Set the zeroth argument of the
subshell-$as_echo to `as_echo', for better error message.
2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
`BASH_SOURCE' contain a newline, set them to empty, as they may
not be unset.
2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
years and is too hard to maintain now. The last straw was
reported by Jerker Baeck in
<http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
* NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
* doc/autoconf.texi (Particular Functions): Move
AC_FUNC_SETVBUF_REVERSED from here...
(Obsolete Macros): ... to here. Say that it does nothing now.
* lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
Turn into (almost) a no-op.
* lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
(AC_C_VOLATILE):
Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
These macros are obsolescent and new applications shouldn't need them.

* doc/autoconf.texi (Setting Output Variables): Mention that
@VAR1@VAR2 has unspecified behavior. Problem reported by
Ralf Wildenhues.
* NEWS: Mention this.
* Makefile.am: Put only a single '#' into the copyright notice,
so that it's also present in the output file. Standardize wording
in makefile copyright notices to match GNU coding standards.

one-line file.
2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
in the sed script that mangles the awk script: delete up to the
first exclamation mark only.
* tests/torture.at (Substitute and define special characters):
Test '!' too.
2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
Rewrite config files generation: avoid quadratic growth in
the number of substituted variables by using awk instead of sed
for the bulk of the substitutions.
* NEWS: Mention this.
* doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
forbidden in the output (and thus input) file.
* lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
(_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
generate just one large awk script for substitutions,
eliminating much of the earlier complexity, while adding some
new complexity. Only expand the substitution templates at
configure time, for smaller configure script size. If
_AC_SUBST_FILES are used, test 'awk' for working getline support
at config.status time. If absent, interpolate through the
shell. The awk script was written with much help
from Paolo Bonzini and Paul Eggert.
(_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
(_AC_SED_FRAG_NUM): Likewise.
(_AC_SUBST_CMDS): Renamed from...
(_AC_SED_CMDS): ...this.
(_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
* tests/torture.at (Substitute a 2000-byte string): Also
substitute a line with 1000 words, and a variable with several
long lines.
(Substitute and define special characters): Test awk special
characters, and put substitution input strings `@foo@' in the
output, to test that no recursion happens; test several other
combinations from Paolo Bonzini.
2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
* lib/autotest/general.m4 (AT_INIT): Undo recent changes
that replaced echo with AS_ECHO where this wasn't necessary.
Problem reportd by Ralf Wildenhues.
* lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
where "/usr/bin/printf '%s\n' S" dumps core if S is long.
This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/freeze.mk (GREP): Removed, no need to initialize this.
2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Limitations of Usual Tools): Don't claim
that traditional Awk lacks 3-arg "split". It has it.
Mention that FS must be a single character, and a few other
99-byte limits of traditional Awk.
Mention that if (i in a) doesn't work with traditional Awk.
2006-11-18 Paul Eggert <eggert@cs.ucla.edu>

(BS-BS-newline in command, BSx640-newline in command):
(Newline-CODE-BS-newline in command):
(Single-quote-BS-newline in command):
(Single-quote-newline-BS-newline in command):
Use printf '%s\n' instead of echo, for portability to hosts
where echo interprets backslashes. This will break on hosts
that lack printf, but for now let's assume all such hosts
are dead (if not, we should get reports of test failures).
2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
'echo' has some portability problems, when given a first argument
with a leading '-', or when given any argument containing '\'.
Avoid using 'echo' in these cases.

scheme wouldn't work with AS_ECHO.
* lib/autotest/general.m4 (AT_INIT): Likewise.
* lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
Don't use ECHO_T, since ECHO_N is now reliable.
* lib/autotest/general.m4 (AT_INIT): Likewise.
* lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
rather than using a here-document to put the script into a file.

use AS_ECHO.
* lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
* lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
bug, but we might as well stop using ECHO_N and ECHO_C internally.
* lib/autotest/general.m4 (AT_SETUP): Likewise.
* lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
(_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
operand, as AS_ECHO requires. Avoid double file name expansion.
* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
Don't set as_nl, since _AS_ECHO_PREPARE does that now.

(Imported from Automake.)
* build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
which incorrectly sets the mode of an existing destination
directory. In some cases the unpatched install-sh could do the
equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
system. We hope this is rare in practice, but it's clearly worth
fixing. Problem reported by Alex Unleashed in
<http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
Also, don't bother to check for -m bugs unless we're using -m;
suggested by Stepan Kasal.

Use a better substitute, by inspecting the output of "ls"
rather than just using ":".
* lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
rather than AS_EXECUTABLE_P, since we needn't worry about
non-regular files here.

set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag

nobody uses it.
(_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
with werror_flag and conftest.err and so forth. This is more
compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
and anyway the user shouldn't normally want to see this gorp logged.
Problem reported by Ralf Wildenhues.
* lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
empty, not 'no', since the rest of the code uses 'test -z'.
2006-10-04 Paul Eggert <eggert@cs.ucla.edu>

AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.

broken lex libraries like native ia64-hp-hpux11.22; see
<http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
work around the problem by preferring an empty LEXLIB to -lfl or

2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
Require that long long int be at least 64 bits wide. C99 requires
this and enough programs depend on it so we should check for it.
Bruno Haible reports in
<http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
that long long int is 32 bits wide with some nonstandard compilers.

2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi: Be more consistent about using @acronym with
"HP" and "HP-UX". Remove mention of OSF; the old version wasn't
quite right (it talked about "OSF/Tru64", even though the
operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
and it even mentioned "OSF 4"!) and at this point there's little
reason to talk about OSF any more, since it died in 1994.
(Specific Compiler Characteristics): Simplify example of
negative-size array.
(File Descriptors): Reorder to make the text flow better.
Remove joke about "appreciate the various levels"; I didn't get it.
Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in

* lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
-lXt in LIBS, idea from Karsten Hopp; this was due since
this change:
2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
(which belong to Xt, not X itself). See Debian bug 327655.
2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

output file.
2006-06-20 Paul Eggert <eggert@cs.ucla.edu>

to int.
2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* bin/autom4te.in (handle_output): Do not forbid the empty
pattern.
* tests/tools.at (autoconf: the empty token): New test.
2006-06-20 Stepan Kasal <kasal@ucw.cz>
* lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
calls, so that we do not care whether they are LIFO or FIFO;
in the m4_wrap, do not check which diversion is the topmost
one, just check that the stack is balanced at the end.
* lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
base diversion forever--pop the previous diversion before
opening the new one; consequently, remove the m4_wrap call.
* lib/autotest/general.m4 (AT_INIT): Likewise.
* tests/m4sugar.at: Do not use
m4_wrap([m4_diversion_pop([..])]), for educational purposes.
2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* NEWS: Document that m4wrap/m4_wrap might not be LIFO.

Rework example of m4wrap token-pasting trouble so that it doesn't
care whether it's LIFO or FIFO.
Fix some "contrary to"s that are awkward in English.
2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
to `yes' instead of `int$1_t' if the type is found, for more
consistent configure output (where $1 is the number of bits).
(_AC_TYPE_UINT): Likewise for `uint$1_t'.
Suggested by Bruno Haible.
* lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
with system headers. Report by Bruno Haible.
2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* config/config.guess, config/config.sub: Sync from upstream.
* bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
in order to avoid picking up an older installed frozen m4sh.m4f.
Besides an outdated shell startup, this could have been created
by an earlier M4 version with incompatible frozen file format.
2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
* README: Recommend m4 1.4.4 instead of 1.4.3..
* doc/autoconf.texi: Likewise.
(Special Chars in Names): Say that $(.FOO) is portable, as
suggested by Stepan Kasal.
(Installation Directory Variables, Build Directories):
(Automatic Remaking, Subdirectories, Fortran Compiler):
(Making testsuite Scripts, Defining Directories):
Quote variable usages better.
(Making testsuite Scripts): Add clean-local rule to makefile
snippet, by Eric Blake.
(Installation Directory Variables): Fix table item font.
Reword slightly to clarify. Generalize advice about
not using special characters to include all file-related
vars, not just VPATH.
(Special Chars in Variables): Warn about special characters in
$(srcdir) too.
(Assignments): Clarify default-value example as suggested by
Ralf Wildenhues in
<http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.

Ralf Wildenhues.
2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* doc/autoconf.texi (Configuration Actions): Remove duplicate
`@var', for texi2html.
(Systemology): Some more word wrapping, for DVI output.
(autom4te Invocation): The short option for `--melt' is `-M',
not `-m'.
2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi: More formatting and English tweaks,
many suggested by Ralf Wildenhues.
Reword to avoid "@code{...}'s" and the like, since it's ugly
with Emacs info mode. discontents -> woes.
Put a few "will"s back. time stamp -> timestamp.
side-effect -> side effect.
2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Initializing configure, Shell Substitutions):
Warn about $@ not persisting. Problem reported by Julien Danjou in

(Special Chars in Names): Renamed from Leading _ in Macro Names.
Mention other special chars, too.
2006-06-14 Eric Blake <ebb9@byu.net>
* doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi: Some systematic minor improvements, as
follows. Use "makefile" when talking about makefiles
generally (which might be named "makefile" or "Makefile" or even
"foo.mk"), "Makefile" when talking about a specific makefile
called "Makefile". This unclutters the text from weird quotes
(e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
values" rather than "@var{foo}s" and similar constructs containing
"}s". Use "Make rules" rather than "Makefile rules". Minor
English-language improvements. Change the prefix "sub-" to "sub"
and "re-" to "re".
Put blank lines around examples more consistently.
Avoid "rather" and "very" as intensifiers.
Avoid "will" as an auxiliary.
(Limitations of Make): Split this node into....
(Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
(Leading _ in Macro Names, Backslash-Newline-Newline):

(VPATH and Double-colon, $< in Explicit Rules):
(Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
(Make Target Lookup, Single Suffix Rules, Timestamps and Make):
New nodes, resulting from splitup of Limitations of Make.
All cross-references changed. Raise the top node from
a section to a chapter, and all subnodes accordingly.
Redo the introductory wording to match the new organization.
(Installation Directory Variables): Use an example that is
closer to what Autoconf actually does. Mention that VPATH's
value should not contain metacharacters or white space.
(Fortran Compiler): Fix a VPATH bug in an example.
(Leading _ in Macro Names): Mention that this problem is no longer
of practical concern.
(VPATH and Make): Reword the advice to make it clearer
that Autoconf and Automake support VPATH in non-GNU make, but
many packages have bugs in this area.
($< in Explicit Rules): Refer to Build Directories rather
than using a (non-VPATH-safe) example.
(Automatic Rule Rewriting): Mention the sort of disaster that
can ensue with Solaris-style rule rewriting with VPATH.
2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* doc/install.texi (Compilers and Options): Weaken the
suggestion to use GNU make for VPATH builds.
* lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.

in regular expression.
2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

Drop extra @samp from `@table @samp' item.
(Limitations of Usual Tools): Comment fix.
Do not nest @samp just to point to other table items.

do not use @var in the second argument.
2006-06-07 Paul Eggert <eggert@cs.ucla.edu>

Omit longwinded and obsolescent discussion of cp -f.
Modernize discussion of expr, ls.

about csh. Don't say "configure" takes awhile; say it
might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,

* lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
comment.
2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
argument with leading hyphen. Problem reported by Paul Eggert.
2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
about quoting ac_try: quote all of it, if any of it seems suspicious.
This means we don't have to worry about ${ or sed any more.
Also, double-quote the case statement, to work around misuses via
underquoting as reported by Ralf Wildenhues in
<http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
(_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
undocumented and dangerous macro.
Problem reported by Ralf Wildenhues in
<http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
`dirname -- /' returns `/', for SunOS dirname scripts that escaped.
Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
since evidently some packages rely on the old, broken behavior.
Problem reported by Ralf Wildenhues in
<http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
(AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
pre-2006-05-26 definitions, but leave in the comments that
these macros are dangerous and should not be used.
(_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
(_AC_DO): Renamed from _AC_EVAL. All callers changed.
(_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
(_AC_DO_VAR): Renamed from AC_TRY_EVAL.
(_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
the use of 'tr', since this is our only use of 'tr'.
2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
and Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
Don't assume 'grep' works on long lines, since AIX grep doesn't.
2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
the output file in the `${datarootdir}' test.
2005-05-28 Stepan Kasal <kasal@ucw.cz>
and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
mention of `datarootdir' in the input file(s), but literal
`${datarootdir}' in the output file, and we haven't warned yet,
then warn as well: the user may have (erroneously) used
`AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
`AC_SUBST([mydatadir], ['${datadir}/my'])'.
* tests/torture.at (datarootdir workaround): Extend this test.
* NEWS: Update.
2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
and Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (autoheader Invocation): The first argument to
`AC_DEFINE_UNQUOTED' need not be a literal. Mention the
alternatives and clear up the language a bit.
2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
* NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
ac_config_guess, ac_config_sub, ac_configure.

2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
Don't use the term "thread-safe" to talk about mkdir race
conditions, since the problem is more a process than a thread
issue. Problem reported by Stepan Kasal in:
http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
* lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
the test for 'install' more closely. Look at MKDIR_P first.
Look in the PATH, and at /opt/sfw/bin.
Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
Don't bother to try mkdir -p, since we already check mkdir --version;
just look at the version number. (There's no easy way to check
for race-free implementations.)
* tests/tools.at (autoconf: subdirectories): Adjust to above
changes, since MKDIR_P now might end in "/mkdir -p".
* doc/autoconf.texi (autoheader Invocation): Mention that the
first arg of AC_DEFINE_UNQUOTED must be a literal.
Problem reported by Ben Pfaff in
<http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
* NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
* doc/autoconf.texi (Special Chars in Variables): New section.
(Preset Output Variables): Warn about special chars in CPPFLAGS.
(Installation Directory Variables): Quote $(datadir) better.
(Limitations of Builtins): Describe some of eval's trickiness.
* lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
* lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
in front of every arg, not just trailing args. Quote apostrophes.
(_AC_EVAL_ECHO): New macro.
(_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
(AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
removed.
(_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
exposed by quoting of eval argument. Put the command on line line
so it logs better.
* lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
(_AC_PATH_X, AC_PATH_X): Quote more safely.
* lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
* lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
* lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
Handle special chars in prefix, ac_srcdir, ac_aux_dir.
Use eval more safely.
(_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
* lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
to be replaced.
* tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
lines, exposed by quoting of eval argument.

and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
initialization of `ac_cv_exeext', do not override it if it was
already set, unless it was set to `no', for compatibility with
Autoconf-2.13, and comment this.
Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
(_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
(_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
* doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
Document that this test may be overridden by setting
`ac_cv_exeext'.
2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
Revert these two patches:
2006-04-06 Eric Blake <ebb9@byu.net>
* lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2006-04-01.
2006-04-01 Stepan Kasal <kasal@ucw.cz>
Clean up _AC_COMPILER_EXEEXT* macros.
* lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
ac_file to the name of the default output file and call
_AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
initial `rm' of the candidate files...
(_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
the same list in subsequent `rm' calls, and for the temporary
redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
(_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
(_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
no longer needed) by libtool. Make it a cache check.
(_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
copied here by mistake.
(AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
_AC_COMPILER_EXEEXT.
* lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
_AC_COMPILER_OBJEXT directly.
* lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
Fix description of how the buggy `sed' works.
2006-05-25 Noah Misch <noah@cs.caltech.edu>
Sync from Automake:
* lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
ENOLCK. Only mention `make -j' when applicable. Only raise
fatal errors when `make -j' is involved. Improve error message.
2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* doc/autoconf.texi (Here-Documents): We now know more about
the variable expansion in here documents bug.
Thanks to Tim Rice and Stepan Kasal.
* doc/autoconf.texi (Making testsuite Scripts): Add an example
how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* tests/autotest.at (Multiline command from M4 expansion):
No failure to be expected if the shell quotes newlines in
commands in the `set -x' output. Report by Tim Rice.
* THANKS: Update.
2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
expansion in the here-documents used by config.status, as that
runs afoul of the Korn shell version M-12/28/93d bug described in
the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
<http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2006-05-23 Jim Meyering <jim@meyering.net>
* lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
Fix typo introduced with 2006-04-02 change. It reversed the sense
of the test.
2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
ac_dB slightly, to save bytes in the script.
Max out at 50 lines, rather than 96; this is more likely
(though not guaranteed) to avoid obscure 'sed' failures.
2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
`tr -d -' as bad option argument. Work around this by deleting
an unrelated character.
Report by Tim Rice <tim@multitalents.net>.
2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
Stepan Kasal <kasal@ucw.cz>
* doc/autoconf.texi (Particular Programs): Do not promise that
we always prefer the GNU version of the program, and that we
search according to PATH; both rules can have exceptions.
Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
AC_PROG_SED. Move descriptions of limitations
to the Limitations of Usual Tools section.
(Limitations of Usual Tools) <sed>: Mention script length
limitations with Solaris /usr/ucb/sed.
<grep>: Fix wording for empty alternative. Mention that -c and
-l should not be combined, and that -E and -F should not be
combined.
2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
limits in Solaris 8 /usr/ucb/sed by testing a long script.
2006-05-22 Stepan Kasal <kasal@ucw.cz>
* doc/autoconf.texi (Defining Symbols): Literal parameter of
AC_DEFINE is now passed to m4_pattern_allow.
* NEWS: Mention that; likewise for AC_SUBST.
* lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
the parameter to m4_pattern_allow.
* tests/tools.at: Add a check for that.
2006-05-22 Stepan Kasal <kasal@ucw.cz>
* lib/autoconf/status.m4: Fix typos.
2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
only the files that this macro generates.
2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
the HP-UX sed limitation of 99 commands, labels do not count.
* lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
in the comment.
(_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
Import the following fix from coreutils:
2006-01-13 Jim Meyering <jim@meyering.net>
Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
$ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
not double-quote uses of that variable, to accommodate the rare
case in which getmntent is available in none of the libraries
checked. This happens at least on FreeBSD 5.0.
2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
ac_config_guess, ac_config_sub, and ac_configure, since evidently
some other programs unwisely rely on these undocumented vars.
But put in warning comments about them.
Problem reported by Ralf Wildenhues in
<http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
* NEWS: Document that these variables are intended to go away.
2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
and set the language to C++ (analogous to the equivalent Fortran
tests).
* lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
* doc/autoconf.texi (C++ Compiler): Document it.
* lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
* NEWS: Update.
2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
that caused config.status to generate 100-command sed scripts; the
portable limit is 99.
2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
variable `ac_d' instead of `d' to avoid infringing namespace.
Report by Ralf Menzel.
2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
$ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
* tests/tools.at (autoconf: subdirectories): New test, taken from
the corresponding problem report by Ralf Wildenhues in:
http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
* lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
Quote some uses of shell variables if they might suffer unexpected
globbing. This doesn't fix all instances of quoting problems that
I found, just the easy ones that look safe.
* lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
(AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
(AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):

2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* bin/autoreconf.in ($help): Reword according to the manual.
Suggested by Olly Betts.
2006-05-17 Olly Betts <olly@survex.com> (tiny change)
and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* bin/autoreconf.in: Pass the directory argument to
`require_configure_ac'. Fix comment.
* tests/torture.at (Configuring subdirectories): Expose this.
Reported by Olly Betts.
2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
Automake as follows:
* lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
`$configure_in' instead of `configure.in', to preserve
directory component.
2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* config/config.guess, config/config.sub, config/texinfo.tex,
doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
test for C99 conformance; (bool) 0.5 is an integer constant
expression, but (bool) -0.5 is not. Problem reported by Fedor
Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
Warn about obsolete install-sh files. Remove stray sentence
fragment and fix cross reference.
* lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
install -d; this undoes the 2006-05-10 change.
(MKDIR_P): Mark with AN_MAKEVAR.
(AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
that we don't require $INSTALL to be thread-safe. Move comments
out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
of AC_PROG_INSTALL. Output a message saying that we're checking
mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
MKDIR_P instead of AC_SUBST.
* lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
Special magic for MKDIR_P, too.
* lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
a dnl.
* tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
Sync from Automake, as follows:
2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* config/install-sh: Initialize IFS, so field splitting isn't
turned off later.
* config/mkinstalldirs: Likewise.
* config/missing: Remove superfluous quotes. Replace all uses of
`[' by `test', for consistency, and for..
* config/missing (sed_minuso, sed_output): New variables.
(autom4te, help2man, makeinfo): Use them. Unifies detection of
`-o FILE', `--output FILE', `--output=FILE', stricter regex.
Fixes `missing' to detect `--output' for help2man. Fixes
PR automake/483. Report by Dennis J. Linse.
(autom4te): Document in `missing --help'.
2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
* NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
* config/install-sh: Don't use 'path' to talk about file names,
as per GNU coding standards. Close a race condition reported by Ralf
Wildenhues and Stepan Kasal. There is still a race condition
on hosts that predate Posix 1003.1-1992, but we can't help this.
Don't mishandle weird characters like space on pre-Posix hosts.
Invoke mkdir at most once per dir arg on pre-Posix hosts.
* doc/autoconf.texi (Programming in M4sh): Cross-reference to
AC_PROG_MKDIR_P from AS_MKDIR_P.
(Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
from mkdir. Mention that Autoconf 2.60 install-sh is safe but
earlier editions are not (including Automake 1.8.3).
Do not suggest mkinstalldirs for thread-safety.
* lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
* lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
presence of special characters and race conditions.
* tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
in Autoconf's name space.
2006-05-10 Bruno Haible <bruno@clisp.org>
and Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
from Automake with minor changes.
* doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
* config/install-sh: Update to Automake CVS version, as follows:
2006-04-25 Stepan Kasal <kasal@ucw.cz>
* lib/install-sh: Simplify the expr implementation of dirname.
2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
* lib/install-sh: Handle --, and diagnose unknown options.
2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
`./autom4te' to create `./testsuite', since the `all' target
will ensure its presence, but `installcheck' should not create
the uninstalled wrappers.
* tests/torture.at (Unusual Automake input files): Skip if we
detect automake < 1.8.
2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
is set to `no', then that overrides and sets ac_cv_prog_cc_c89
and ac_cv_prog_cc_c99 to `no', for backward compatibility.
* NEWS: Update.
2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
munge (multiple) white space and other oddities.
* tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
single quotes in variable assignment.
(AC_ARG_VAR, configure invocation): Adjust tests to expose this
and similar failures by adding multiple spaces, tabs, and other
special characters.
Report and different test suggested by Francesco Romani
<fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
* lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
single quotes, we only need to search for single quotes; this
both simplifies the search pattern, and makes us less
susceptible to `echo' variations for arguments not containing
single quotes.
(_AC_ARG_VAR_VALIDATE): Likewise.
2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* doc/autoconf.texi (Special Shell Variables) <IFS>: Document
`$*' and IFS concatenation issue with traditional shells and
bash-2.04. Report by Seanster@Seanster.com.
2006-05-03 Bruno Haible <bruno@clisp.org>
* doc/autoconf.texi (Limitations of Usual Tools): Identify more
precisely which Mac OS X versions have the od problem.
2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi: Use @option systematically.
2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
and Bruno Haible <bruno@clisp.org>
* doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
about 'od'.

since as_me isn't set yet.
2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
a few minor bugs in this area.

* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
newline from the `trap' code to finish `config.log'; the NetBSD
/bin/sh resets the exit status after an empty command, as
documented in doc/autoconf.texi.
Reported by Dalibor Topic <robilad@kaffe.org>.
2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
Suggested by Bruno Haible.
2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
* configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
Instead, just list the shells that we know work.
* tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
changed. Be more cautious about the _cv_ variable.
* tests/tools.at (Syntax of the shell scripts): Check the
_cv_ variable once, at first, to avoid an internal autoconf error
when sh -n does not work.
2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/Autom4te/FileUtils.pm: Sync from Automake.
2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
use ">&-" since we're only 99.999% sure that this is portable,
and since the MinGW bug is fixed in a different way.
* lib/autotest/general.m4 (AT_INIT): Likewise.
2006-04-16 Stepan Kasal <kasal@ucw.cz>
* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
before opening config.log, to avoid hitting a bug on MinGW.
2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
AS_MESSAGE_LOG_FD before reopening it onto the log file.
This works around a MinGW bug reported by Eric Paire.
Make sure that all writes to the log file append to it,
rather than possibly losing data.
* lib/autotest/general.m4 (AT_INIT): Likewise.
2006-04-14 Stepan Kasal <kasal@ucw.cz>
* lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
description.
2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
Version 2.59c.
* Makefile.maint (news-date-check): Do not require a leading `*'
before the release date in NEWS.
2006-04-12 Stepan Kasal <kasal@ucw.cz>
and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
the instantiated file do not contain the string 'datarootdir'
but contain @datadir@, @docdir@, @infodir@, @localedir@, or
@mandir@, replace the reference '${datarootdir}' by the value.
* tests/torture.at (datarootdir workaround): New test.
* NEWS: Advertise this temporary fixup.
Based on a patch by Bruno Haible, reported and analyzed by
Paul Eggert and Noah Misch.
2006-04-12 Eric Blake <ebb9@byu.net>
* tests/autotest.at (Debugging a failed test): Fix comment.
2006-04-12 Stepan Kasal <kasal@ucw.cz>
* lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
all the changes since 2006-04-07.
2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
succeeded, but `ln -s file dir' failed, take care to remove the
leftover target before the next test, to prevent its spurious
failure; also make sure `ln file dir' works before selecting it.
Thanks to Keith Marshall for pointing this out.
* THANKS: Update.
* lib/autotest/general.m4 (AT_INIT): Store quoted variable
assignments in `at_debug_args', so that we put them correctly
in the `run' script.
* tests/autotest.at (Debugging a failed test): Unmark XFAIL.
Reported by Eric Blake.
2006-04-11 Eric Blake <ebb9@byu.net>
* tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
top-level tests after micro-suite has been run. Used in...
(Debugging a successful test, Debugging script and environment),
(Debugging a failed test): ...these new tests. The first of these
is fixed by...
* lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
macro, split out from...
(AT_INIT): ...here, so that using -d also generates a run script.
Document that -d inhibits top-level logging.
* doc/autoconf.texi (testsuite Invocation): Document that -d only
inhibits top-level logging; debug scripts are created.
* lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
check.
* tests/autotest.at (Empty test, Empty check): New test to check it.
* lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
from gcc.
2006-04-10 Stepan Kasal <kasal@ucw.cz>
* tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
the files if a problem appears. Make the empty *.at files
read-only, too. Proposed by Ralf Wildenhues.
2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* config/Makefile.am: Add comment to force updated Makefile.in.
* lib/freeze.mk: Fix typo in comment. Unlike the last, white
space only patch to this file, this patch causes the Makefile.in
files that include freeze.mk to be updated, and thus have a
newer time stamp again, which in turn makes a pristine CVS
checkout have correct time stamps.
* Makefile.maint (cvs-sv): New macro, to be used..
(config.guess-url_prefix, config.sub-url_prefix)
(texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
point to CVS text checkout of Gnulib files.
(copyright-check): Bump current year.
(announcement): Do not hard-wire `./announce-gen'.
(cvs-update): Propagate failures of `cvs' and `move-if-change'
correctly.
* Makefile.cfg (executable-update): Use `chmod a+x' instead of
`chmod +x'.
(wget_files): Update config.guess, config.sub, texinfo.tex by
`wget-update', now that their URLs work again.
2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
Problem noted by Paul D. Smith.
2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* doc/autoconf.texi: Remove unused words from word list.
* .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
.x-sc_trailing_space: New files.
* doc/standards.texi: Sync from gnulib.
* NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
`LIBOBJDIR' as experimental.
* lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
with a target directory; it's internally implemented as `cp'
anyway, but since Autoconf advertises the possibility to use
a target directory when LN_S is `ln -s', we need to find out.
Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
analyzed by Keith Marshall <keith.marshall@total.com>.
* THANKS: Update.
2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
confdefs.h as-is. In general, if it has backslash-newline or the
like, then it doesn't work either to sort or to remove empty
lines.
2006-04-09 Stepan Kasal <kasal@ucw.cz>
* tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
* lib/autom4te.in (Automake-preselections): Preselect
_AM_SUBST_NOTMAKE.
2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
apostrophe within a single-quoted string, as this is the usual
tradition and is easier to read than '"'"'. Don't rely on the
shell treating "$/" like '$/'. Use a more-consistent indenting
style for the trap.
2006-04-09 Eric Blake <ebb9@byu.net>
* tests/autotest.at (Backquote command substitution),
(Multiline backquote command substitution): Remove mistaken
AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
applied...
(Parenthetical command substitution, Multiline parenthetical
command substitution): here.
2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

* lib/autotest/general.m4 (AT_INIT): No need to give three
parameters to _AS_PATH_WALK.

* lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
and DUALCASE=1.
(AS_SHELL_SANITIZE): Remove DUALCASE=1.
* doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
it is set.
2006-04-07 Eric Blake <ebb9@byu.net>
* doc/autoconf.texi (Programming in M4sh): Document that
AS_MKDIR_P exits the script on failure.
* lib/autotest/general.m4: Remove redundant AS_ERROR.

Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
whether `set' quotes correctly: redirect stderr of the tested
`set', and use a subshell, for Ultrix; use `sed' instead of
`grep' for zsh `set' which may write binary output; match only
at the beginning of a line, to avoid false positives.
In order to avoid false positives by unrelated variables with
multiline content, put the dump algorithm in a subshell and
unset all variables containing newlines (except some which are
special to the shell). Warn about cache variables that are
unset.
2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

for --help from Cygnus `configure.'
2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

whereby substrings were incorrectly matched, causing us to not
generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
(exclude_list): Exclude empty macros.
(ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

Clean up _AC_COMPILER_EXEEXT* macros.
* lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
ac_file to the name of the default output file and call
_AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
initial `rm' of the candidate files...
(_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
the same list in subsequent `rm' calls, and for the temporary

2005-07-25 Stepan Kasal <kasal@ucw.cz>
Rewrite substantial part of lib/autoconf/status.m4.
The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
and CONFIG_COMMANDS are not processed in four separate loops.
Instead, there is one main loop. This alows that the common code
is expanded only once, thus config.status (and configure) is smaller.
The registration mechnism in AC_CONFIG_FILES and cousins also changed;
the AC_LIST_FILES and cousins macros are no longer used.
* lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
_AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
(_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
_AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
contain the initialization, nor the for loop, nor the associated
commands; all these go to ...
(_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
_AC_OUTPUT_CONFIG_STATUS.
(_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
(_AC_OUTPUT_FILE): The creation of the sed script ...
(AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
(_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
_AC_OUTPUT_MAIN_LOOP.
(_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
_AC_CONFIG_COMMANDS): Use ...
(_AC_CONFIG_FOOS): ... this new macro, which uses these ...
(_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
(_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
_AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
(_AC_CONFIG_DEPENDENCY): Update, it uses these ...
(_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
... new macros.
(_AC_CONFIG_UNIQUE): Update.
(AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
Replaced by this ...
(_AC_LIST_TAGS): ... new common macro.
(AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
AC_LIST_COMMAND_COMMANDS): Replaced by this ...
(_AC_LIST_TAG_COMMANDS): ... new common macro.
(_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
this didn't belong to the `config commands' section.
(_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
(AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
to the `config commands' section either.
(AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
(_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
... and many changes to the comments nearby.
* lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
set ac_subdirs_all='_AC_LIST_SUBDIRS'.
* tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
(#define header templates): The comment at the top of the generated
header now includes the name(s) of the source file(s).
Several unrelated small changes:
* lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
parameter to AC_DIAGNOSE.
* lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
(_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
(AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
with AU::AC_OUTPUT.
(AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
in AC_OUTPUT doesn't double-quote it either.

addition.
2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

to update the man page. That way, we don't have to check in new
man pages every month.

quotes and backslashes. Patch from Derek Price.
2005-06-10 Derek Price <derek@ximbiot.com>

AS_TR_SH.
2005-06-08 Paul Eggert <eggert@cs.ucla.edu>

-u, since it outputs chatter if the input files are the same.
Problem reported by Ralf Menzel.
2005-06-08 Derek Price <derek@ximbiot.com>
* lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than

Clarify explanation of HP compiler bug.
Redo example output tp match current CVS snapshot.
Use @example.org in email addresses when the examples
might get inadvertently cut-and-pasted into user code.
Remove example of autom4te usage that doesn't seem to work now.
Use modern AC_INIT (except when the example is meant to be
shown with Autoconf 2.13).
Update ksh info for Solaris 9 and later.
KB -> kB.

Nicolas Joly <njoly@pasteur.fr>.
2005-06-06 Stepan Kasal <kasal@ucw.cz>
m4_cdr of one-member list was [[]] (one-member list containing an
empty string) instead of [] (an empty list. Callers were skewed to
match this misbehaviour. As a consequence of this:
- m4_foreach([x], [], [foo]) expanded to `foo', while
- the expansion of m4_foreach([x], [[]], [foo]) was empty.
This bug has been fixed:
* lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
expand to an empty string; print error msg if called without
an argument list.
(m4_foreach, m4_map, m4_map_sep): Don't expect the previous
misbehaviour; handle [] and [[]] correctly.
2005-06-06 Stepan Kasal <kasal@ucw.cz>
* lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

to workaround this limitation.
2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
* lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
to gfortran, and make these the first two compiler names
checked (following the general autoconf preference for gcc).
2005-06-03 Stepan Kasal <kasal@ucw.cz>
* tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).

* lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
now contain newlines, and substituted files must be referenced on
a line alone; the sed scripts to substitute them are now very
different.
(_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
commands can be put in a sed script portably.
* doc/autoconf.texi (Setting Output Variables): Document above
changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
use of multiline substitution.

From Ralf Menzel (trivial change).
2005-05-25 Paul Eggert <eggert@cs.ucla.edu>

* bin/Makefile.am: Merge the two rules for creating scripts.
2005-05-23 Stepan Kasal <kasal@ucw.cz>

obsolete; it was never documented.
(AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
2005-05-20 Stepan Kasal <kasal@ucw.cz>

* lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
``cat <<_ACEOF'' commands to one.
(_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''

Merge `-z option' as well for the benefit of Solaris link flags. Pass
whole-archive (-zallextract, -zdefaultextract) options in the hope of
unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
* NEWS: The configure command now warns you if you attempt to use
a directory whose name contains a special character like space,
newline, or "\".

ac_pwd, and quote srcdir.
* lib/autotest/general.m4 (AT_INIT): Quote file name args.

".)" needs a following @: if not at the end of a sentence, and
similarly for "!)". "etc." should be preceded by a comma.
"n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
2005-03-22 Bruno Haible <bruno@clisp.org>

2005-02-24 Stepan Kasal <kasal@ucw.cz>
* lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
`/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
from a Common Lisp's `cl'.
(AC_PROG_CXX): Behave according to the documentation: don't
search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
make the variable CCC precious; use `cl.exe', not `cl'.
2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
Alexandre Duret-Lutz <adl@gnu.org>
* lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
/dev/null, as "configure" shouldn't read stdin, and this insulates
us from problems (e.g., when testing for "cl"). Also, do this
redirection before invoking "hostname" or "uname", and keep the
original input stream available via...
(AS_ORIGINAL_STDIN_FD): ... this new macro.
(_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
bother with "</dev/null" since it's now done at the top of
'configure'.

2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
* lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
newline if neither \c nor -n work, as that would output two
newlines. Prefer -n to \c. Reported by Stepan Kasal.
2005-02-12 Stepan Kasal <kasal@ucw.cz>
* lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
This causes that any required macros inside will get before the if.
* doc/autoconf.texi (autom4te.cache): A typo.
2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
Undo previous change, except keep the change to
lib/autoconf/programs.m4 that replaced grep with shell
pattern-matching. This is because net-snmp configure reads stdin.
Reported by Noah Misch.
2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin

Suggested by Alexandre Duret-Lutz. Also, do this redirection
before invoking "hostname" or "uname".
(_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
_AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
* lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with

avoid thinking that Allegro Common Lisp's "cl" command is a C++
compiler.
2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Limitations of Usual Tools): Document that
grep -q isn't portable. Improve grep -s explanation.
Problem reported by Dan Manthey.
2005-02-08 Paul Eggert <eggert@cs.ucla.edu>

* tests/local.at (AT_CMP): Use diff directly on input files rather
than copying them.
* lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
/usr/xpg4/bin since that sed dumps core (at least on Solaris 8).

2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
* lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
Try not to generated lines of unlimited length, as POSIX places a
2047-byte limit on line length of portable text files.
* lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
Use newline as a separator, not space.
* lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.

are restored after function return.
2005-02-02 Paul Eggert <eggert@cs.ucla.edu>

Fortran 95 (newer Crays).
2005-02-01 Paul Eggert <eggert@cs.ucla.edu>

care to echo the commands, so the user knows what's going on.
Modified from a suggestion by Stepan Kasal.

2005-01-29 Stepan Kasal <kasal@ucw.cz>
Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
Update the long comment explaining it.
m4_require no longer writes an ``is required by'' line to the
execution stack. It contains only one bit of non-redundant
information: that the macro was required, not called. And even
this bit is useless in most situations: have you ever met a macro
which both calls and requires the same macro?
* lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
(_m4_defun_pro_outer): ... only via this macro, for the outermost
macro.

* tests/m4sugar.at (m4_require): Expect output without the
``is required by'' messages.

stripping.
2005-01-19 Stepan Kasal <kasal@ucw.cz>

A cleanup of the diversion support in m4sugar.
* lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
(_m4_divert_n_stack): New macro; the expansion is
<newline>m4_divert_stack, if m4_divert_stack is defined, and void
otherwise.
(m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
(m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
stored in _m4_divert_diversion or _m4_divert_dump.
(m4_divert_pop): When the parameter is given, compare the symbolic
name with the last diversion pushed on the stack. Previously, the
current diversion was compared with the numeric value of the
diversion given as the parameter.
(m4_require): If the macro hasn't been expanded yet, call ...
(_m4_require_call): this new macro.

the spaces inside $ls_command. Problem reported by Loulou Pouchet in
<http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
Don't use "set - x"; plain "set x" is enough, and simplifies debugging.

* lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
"char c = '\200';" rather than "char c = 0x80;" as the
latter doesn't conform to the strict C standard due to
overflow on signed char hosts.
* lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
to -qlanglvl=ansi. We don't want to disable extensions.
2004-11-29 Paul Eggert <eggert@cs.ucla.edu>

Use "file name" rather than "filename" or "path",
to be consistent with the terminology of the GNU coding standards.
2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
<http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
More fixes to support spaces in the name of the build directory.
This isn't a complete fix but it's an improvement.

for compatibility with Automake 1.4. Reported by J C Fitzgerald in
<http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
* lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.

with pdksh, too. Problem reported by Patrick Welche via
Gary V. Vaughan.
* doc/autoconf.texi (Shellology): Note that set -o posix is
useful for pkdsh, too.
2004-06-24 Paul Eggert <eggert@cs.ucla.edu>

_AS_UNSET_PREPARE, so that we can use $as_unset directly.
Don't fail if ENV or BASH_ENV is readonly.
(AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,

(trivial change)
2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (File System Conventions): Warn about
names like "aux". Problem reported by Eric Blake.
* lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
by zero instead of array size, so that we can use any arithmetic
constant expression (instead of requiring an integer constant
expression). This allows us to test expressions like DBL_MAX <
LDBL_MAX, which didn't conform to the C standard using the old
method.
(AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
now that we can do floating-point tests at compile time.
2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
and LDBL_EPSILON, as the resulting expression isn't an
integer constant expression and violates the C standard.
Problem reported by Nelson H. F. Beebe. Also, check
for "L" suffix, and check that long double doesn't have
worse range or precision than double, that mixed-mode
arithmetic doesn't generate a diagnostic, that double
constants fit in long double.
2004-06-03 Kevin Ryde <user42@zip.com.au>
* doc/autoconf.texi (Function Portability): Add notes on free(NULL),
malloc(0) and realloc(NULL,size).

Problem reported by Stepan Kasal.
2004-05-24 Paul Eggert <eggert@cs.ucla.edu>

change). Patch reported by Ralf Wildenhues in
<http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
* lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
function F exists if the compiler and linker let you compile an
expression like (F != 0). Recent versions of GCC optimize away
the reference to F in that case, since every function address must
be nonzero, so the link succeeds even if F does not exist.
Problem reported by Manu in
<http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
* doc/autoconf.texi (Systemology): Standardize on the spelling of
"Unix". Many uses changed.
(Limitations of Builtins): Explain better why the ! command isn't
portable.
2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
* lib/autom4te.in (Automake-preselections): Preselect
LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
2004-05-19 Kevin Ryde <user42@zip.com.au>
* doc/autoconf.texi (Function Portability): Add strerror_r, cross
referencing AC_FUNC_STRERROR_R.
* doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
note pessimistic assumption when cross compiling.
2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Limitations of Make): Note that BSD make
(until 2004) invoked subcommands with sh -e, contra POSIX.
Reported by Kevin Ryde.
2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
* programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
_AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
" $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
`test -f " /usr/bin/grep"', which _always_ failed.
(AC_PROG_SED): Ditto bogus PATH fix.
* autoconf.texi (AC_PROG_GREP): Properly document that this macro
requires that grep correctly supports _multiple_ `-e' options, rather
than stating only that grep should accept `-e'.
2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
Port to C99, which requires that 'exit' be declared.
* lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
to ensure that stdlib.h is included.
* lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
_AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
* lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
* lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
* lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
when using 'exit' in a test; C99 requires that 'exit' be declared.
2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Particular Programs): AC_PROG_GREP
now prefers 'grep' implementations that accept -e.
(Limitations of Usual Tools): Describe problems of traditional
egrep and fgrep with long input lines, and of traditional grep
with -e.
* lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
(_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
All callers changed. Append /usr/xpg4/bin to the PATH, for
Solaris.
(_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
the user with complaints about multiple -e options.
* tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
Define it with AC_PROG_GREP.
* configure.ac (AC_PROG_GREP): Add.
* lib/freeze.mk (GREP): New macro.
2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
* lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
a possible candidate only after all others fail, rather than
consulting it first. This improves backward compatibility by
better reflecting the way shell selection occurred in previous
versions of Autoconf, and should help to avoid triggering latent
problems in other packages, such as the one in Automake where zsh
is not handled robustly:
http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
Although it is not Autoconf's responsibility to work around
problems in Automake, it nevertheless makes sense to avoid
introducing unnecessary incompatibilites.
2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
Gary V. Vaughan <gary@gnu.org>
* lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
how deeply nested we are when a suitable tool is found, set the
ac_path_TOOL_found flag.
(_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
nested we are in this macro. Break out of all 3 nested loops if
ac_path_TOOL_found is set.
2004-04-21 Gary V. Vaughan <gary@gnu.org>
* lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
of the _AS_PATH_WALK loop too if GNU flavor is found.
2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
* doc/autoconf.texi (Limitations of Make): Update documentation
for `$<'. New entry `Long lines', based on a report from Simon
Josefsson. Augment the documentation for SHELL = @SHELL@ with a
paragraph about DJGPP, based on a mail from Richard Dawe.
2004-04-20 Paul Eggert <eggert@twinsun.com>
* tests/c.at (C keywords): Don't assume that GCC supports
"restrict" and "inline", as sufficiently-old GCC versions do not
(also, GCC configured to be in pedantic C89 mode does not).
Problem reported by Sumit Pandya in:
http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
* lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't

http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
* lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
linker output files before linking, to work around IRIX 6 linker bug.
Problem reported by Rainer Orth in:
http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
2004-04-20 Gary V. Vaughan <gary@gnu.org>
* lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
best tool so far counter rely on the tool path variable name to
avoid checks for one tool being affected by the results of running
the length check on a previous tool.
* lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
match expression argument, as different greps have different
regular expression flavours.
(AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
literals.
(AC_PROG_EGREP): Pass 'EGREP$'.
(AC_PROG_GREP): Pass 'GREP$'.
2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
* lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
2004-03-29 Paul Eggert <eggert@twinsun.com>
* doc/autoconf.texi (Particular Headers, Particular Types, Generic
Types, Specific Compiler Characteristics, System Services,
Obsolete Macros): Use 'long int', 'short int', 'unsigned int'

pacify libtool 1.5.2. Fix quoting problems in sed command.
2004-03-28 Paul Eggert <eggert@twinsun.com>
* doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
now defines HAVE_DECL_TZNAME if it is declared, when
HAVE_STRUCT_TM_TM_ZONE is not defined.
* lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
for HAVE_TZNAME.
2004-03-28 Steven G. Johnson <stevenj@fftw.org>
* lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected

inherits from language Autoconf-without-aclocal-m4.
(Customizing autom4te): Adjust example; the cache must now be
disabled for language Autoconf-without-aclocal-m4.
2004-03-16 Paolo Bonzini <bonzini@gnu.org>
Nathanael Nerode <neroden@twcny.rr.com>

behavioral changes.
* tests/mktests.sh: Do not generate tests for the
new macros.

* NEWS: New macro AC_CHECK_ALIGNOF.
* doc/autoconf.texi (Generic Compiler Characteristics): Document it.
* lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
vowel.

* tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
those for sizeof.

POSIX doesn't require support for it. Use $@.in instead.
Problem reported by Anthony N. Frasso in
<http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
* bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
2004-02-23 Gary V. Vaughan <gary@gnu.org>

(MAINTAINERCLEANFILES): Split into pieces,
one per related section. Add $(srcdir)/wrapper.in.
2004-02-09 Paul Eggert <eggert@twinsun.com>
* doc/autoconf.texi (Setting Output Variables): Emphasize that
AC_SUBST provides no portable way to escape literal newlines.
* lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
Darwin uses -lcrt2.o and there's little point to cataloging all
the system variants. Partial fix reported by Andreas Waechter in:
http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
for bug reported by Nelson H. F. Beebe in:

2004-01-26 Paul Eggert <eggert@twinsun.com>
* doc/autoconf.texi (Default Includes): Include <stdint.h> even if
HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
not <inttypes.h>. Problem reported by Tim Mooney in
<http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
* lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
Likewise.
* lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
otherwise "make check" fails because it forbids cmp (I guess
because cmp treats files as binary on DOS-like systems).

with `autoconf -Wall,error'. Bug reported by Eric Blake in:
http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
(_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
AC_COMPILE_IFELSE, since we now assume our caller invokes
AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
(_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
of AC_RUN_IFELSE; this avoids the warning mentioned above.
(_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
2004-01-07 Paul Eggert <eggert@twinsun.com>
* lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside

correspond to all the old F77 macros, with output variables FC,
FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
available dialect, but older dialects can be specified. There are

&parse_WARNINGS.
($help): Use Autom4te::ChannelDefs::usage.
* bin/autoscan.in: Use Autom4te::ChannelDefs.
* lib/Autom4te/General.pm: Don't export error: you don't own it.
2003-08-21 Akim Demaille <akim@epita.fr>
First stab at preserving warnings between calls to autom4te,
including when the cache is used.
There are still several issues: (i) there are too many runs of m4
(one for include, one for warnings, and some more), (ii) warnings
spreading on several lines are not handled gracefully, (iii) the
code meant to have the call stack display for errors does not work
(its handling should move from m4 to autom4te).
* bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
Use them.
(@preselect): Add m4_warn.
($exit_status): Remove, use $exit_code.
($help): Use Autom4te::ChannelDefs::usage.
(&handle_m4): No longer define the m4_warnings.
At each run, extract and report the warnings.
Always cache the result, including if the exit status is on
failure, since if nothing changes, we should result in the same
failure, hence we can use the cache.
* lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
(_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
Remove.
(m4_warn): Redefine as a do-nothing: it is its invocation that
matters, as warnings are now reported via traces.
* lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
the contents of m4_warn: make it _call_ m4_warn, so that tracing
the latter reveals calls to the former.
Adjust the tests.
* tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
2003-08-21 Akim Demaille <akim@epita.fr>
* bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
Use them.
2003-08-21 Akim Demaille <akim@epita.fr>

2003-08-20 Akim Demaille <akim@epita.fr>
* bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
* bin/autom4te: Adjust.
In particular, be Autoconf tools are really silent when properly
working, bind the verbosity of the 'note' channel to $verbose.
* lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
(&xsystem, &contents): Remove, since they are exported by...
* lib/Autom4te/FileUtils.pm: this.
More perldoc.
* lib/Autom4te/General.pm (&up_to_date_p): Move to...

From Gareth McCaughan.
2003-06-23 Akim Demaille <akim@epita.fr>
* lib/autotest/general.m4 (AT_INIT): Report a single config.log,
not all of them. This fixes 1. the fact that when testing
Autoconf there are many many config.log, 2. the incorrect use of
top_srcdir to find config.log.
Don't mix the detailed output of failed test with the summary of
failures. Rather, append detailed log afterwards.

* lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
Remove `#include <stdlib.h>' from the list; we should never
make confdefs.h include <stdlib.h> or <cstdlib>, because the
resulting namespace pollution would cause other tests to fail.
Configure scripts run with some older versions of g++ and HP's
aCC would fail due to such an #include. Problems reported by
Matthew Mueller in <http://bugs.debian.org/120704> and by
Keith Bostic in
<http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
In the test, use the test declaration before including <stdlib.h>,
as that's closer to how it'll be used.

Overhaul Autotest's logging: generate separate log files
in testsuite.dir/NNN/testsuite.log, and append them to
testsuite.log instead of re-running the test verbosely.
* lib/autotest/general.m4 (AT_INIT): Use a single redirected
file descriptor, write 0 to at_status_file instead of setting
at_status=0, initialize some new variables (at_status_file,
at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
to rerun the tests, instead append the at_group_log to the
at_suite_log when a test fails.
(AT_SETUP): pipe the test case's output into at_tee_pipe,
with the AS_MESSAGE_LOG_FD redirected to stdout.
(AT_CLEANUP): save the output status in $at_status_file
and restore it, redirect the AS_MESSAGE_LOG_FD back to
its original place.
(AT_CHECK): since tests are run with a redirected stdout,
and used to be re-run in verbose mode, turn some $at_verbose
into echo, and don't redirect the output of testing stdout
and stderr.

present on the developer's host.
2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>

* lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
_AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
defined, to support freestanding compilers. This should fix the

* doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
obsolete AC_CHECK_TYPE. The missing empty arg was reported
by Simon Josefsson in

2002-11-05 Akim Demaille <akim@epita.fr>
* lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
Remove.
We _have_ to stop using the old compatibility scheme that tried to
avoid useless backslashes because Libtool 1.4.3 contains a
AC_DEFINE([error_t], [int],
[Define to a type to use for \`error_t' if it is not
otherwise available.])
We _have_ to quote the single quote and backslashes with \. The
old compatibility scheme saw that ` was backslashed, and therefore
did not quote the single quote. Hence before this patch, Autoconf
was not compatible with Libtool.
2002-11-04 Paul Eggert <eggert@twinsun.com>

words about HP-UX cmp: it was actually a user-written cmp.
2002-10-22 Akim Demaille <akim@epita.fr>
* tests/foreign.at (Libtool): Don't check autoconf's stderr: there
are a few warnings.

Quote for Perl '' strings, not "".
* bin/autoheader.in: Invoke autoconf to get '' strings, not ""
strings.
2002-10-22 Akim Demaille <akim@epita.fr>
* lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
characters is a syntax warning now.
(_AS_QUOTE): Accept $2 as list of characters to quote.
* lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
Quote for Perl, not sh.
* bin/autoheader.in: When $debug, report the file which is
`do'ne.
* tests/tools.at (autom4te, autoheader): Exercise @bar, not merely
`@', to tickle Perl's lists.
Reported by Carlos Velasco.
2002-10-18 Akim Demaille <akim@epita.fr>
* bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that
missing included files _are_ errors.
Thanks to Alexandre Duret-Lutz.
* tests/tools.at (autom4te cache): Adjust.
* tests/atspecific.m4 (AT_CHECK_AUTOM4TE): New.
(AT_CHECK_M4SUGAR): Use it.
* tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
Adjust.
* tests/tools.at (autom4te): Now it does exit 1.
2002-10-17 Akim Demaille <akim@epita.fr>

/dev/null.
Reported months ago by H. Merijn Brand.
2002-10-17 Akim Demaille <akim@epita.fr>
* tests/tools.at (autoheader): Put randoms `@' to stress Perl.
2002-10-16 Paul Eggert <eggert@twinsun.com>
* Makefile.maint (wget_files): Remove ansi2knr.c.
(ansi2knr.c-url_prefix): Remove.
2002-10-16 Akim Demaille <akim@epita.fr>
Because of caching, some files that no longer exist and are no
longer required can still cause errors.
Reported by Alexandre Duret-Lutz.
* bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
to frozen files in @ARGV, as @ARGV must remain being a list of
files. Rather, at M4 call sites, use this...
(&files_to_options): New function.
(&freeze): Use &error.
(&up_to_date): If a file that was included according to the cache
is no longer there, then the output is out dated.
(&main): Don't even check whether a file is up to date is anyway
--force is given.
* tests/tools.at (autom4te cache): New.
2002-10-16 Akim Demaille <akim@epita.fr>
* bin/autoconf.as: Kill dead options.
* bin/autoupdate.in (&parse_args): Kill old options.
* bin/autoreconf.in (&parse_args): Remove dead options.
Factor some code.
(&autoreconf): Report the directories we enter *and leave*, so
that error messages can be easily located, and use GNU Make
format, so that Emacs' compile mode understands us.
* lib/Autom4te/General.pm (&update_file): Use `verbose' to report
if some file was changed instead of `print'.
* bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
(&parse_args): Remove the dead options.
* tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
autoheader's quiet mode.
(AT_CHECK_AUTOUPDATE): Likewise.

* tests/semantics.at (AC_C_BIGENDIAN): Likewise.
2002-10-11 Akim Demaille <akim@epita.fr>
No longer use CPP to check for the existing of headers: use CC to
check for compilability.
* lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
(AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
(_AC_CHECK_HEADER_NEW): Rename as...

file name to enable parallel executions.
From Sam Varshavchik.
2002-10-08 Akim Demaille <akim@epita.fr>
* bin/autoreconf.in (&autoreconf): Run autopoint before the first
aclocal invocation, as Gettext macros might not be visible to
aclocal.
Instead of blindly running autopoint, scan configure.ac (not the
traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
Reported by Paul D. Smith.
2002-10-08 Paul Eggert <eggert@twinsun.com>
Work around problems found when POSIXLY_CORRECT=1 is set.
None of this seems to have anything to do with POSIX, really,
but it's how Perl getopt works.
* bin/autom4te.in (parse_args): Configure GetOpt with
"permute", too.
* doc/autoconf.texi (Invoking autom4te):
--warning -> --warnings.
* lib/autom4te.in: --warning -> --warnings.

* lib/autoconf/headers.m4, lib/autoconf/libs.m4,
* lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
2002-09-28 Akim Demaille <akim@epita.fr>
* tests/torture.at (Configuring subdirectories): Be robust to
users who use config.site to require for a cache: in this case,
the two last configure runs, using two different sets of
arguments, trigger a legitimate error.
2002-09-28 Akim Demaille <akim@epita.fr>
* tests/m4sh.at (Functions Support, Functions and return Support):
New.
2002-09-28 Akim Demaille <akim@epita.fr>

(make, mawk, nawk, ranlib, yacc): Similarly, move to...
* lib/autoconf/programs.m4: here.
* lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
(ETAGS_FOR_AUTOCONF): New.
Use it.
2002-09-28 Akim Demaille <akim@epita.fr>
* lib/autoconf/autoscan.m4: New file.
* lib/autoconf/autoconf.m4: Include it.
* lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
that were listed in the original autoscan.list.
* lib/autoconf/headers.m4: Similarly with headers.
* lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
(.m4.m4f): Don't pass --prepend-include, since that's done by
tests/autom4te itself.
* lib/autoscan/Makefile.am: Include freeze.mk.
(autoscan.list): New target --this file is no longer a source.
(autoscan.pre): New file.
2002-09-28 Akim Demaille <akim@epita.fr>

* lib/autoscan/autoscan.list: this.
* bin/autoscan.in (&init_tables): Adjust.
2002-09-28 Akim Demaille <akim@epita.fr>
* lib/autoscan/functions, lib/autoscan/headers,
* lib/autoscan/identifiers, lib/autoscan/makevars,
* lib/autoscan/programs: Make the `kind' explicit, i.e., each
`functions' line is now prefixed with `function:'.
* bin/autoscan.in (&init_tables): Adjust.
2002-09-28 Akim Demaille <akim@epita.fr>
From now on, autoscan files must always map a macro name to a
word: there is no `default' macro for autoscan.
* bin/autoscan.in (&init_tables): Reject entries with no macro at
all.
* lib/autoscan/functions, lib/autoscan/headers: Make the macro
explicit.
2002-09-28 Akim Demaille <akim@epita.fr>
* bin/autoscan.in (%c_keywords): Remove.
(&used): Keep only track of the words we might be interested in.
(&output_kind): It is no longer needed to look for non active
checks.
2002-09-27 Akim Demaille <akim@epita.fr>
* lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.

2002-09-27 Akim Demaille <akim@epita.fr>
* doc/autoconf.texi (Limitations of Usual Tools): Some about mv
from /tmp.
Thanks to Bill Moseley and Paul Eggert.
* lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
the tmpdir must be created.
* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
dir be in the build tree, instead of $TMPDIR.
2002-09-27 Akim Demaille <akim@epita.fr>
* bin/autoscan.in: Improve the comments.
(&parse_args): Drop obsolete undocumented options.

Reported by Ralf Corsepius.
* doc/autoconf.texi (autoreconf Invocation): Likewise.
2002-09-26 Akim Demaille <akim@epita.fr>
Single suffix rules and seperated dependencies are not portable.
* doc/autoconf.texi (Installation Directory Variables): Update.
(Limitations of Make): Some about `Single Suffix Rules and
Separated Dependencies'.
* bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
(ifnames, autoscan, autom4te): Un-factor into several rules.
2002-09-25 Paul Eggert <eggert@twinsun.com>

1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
2002-09-24 Paul Eggert <eggert@twinsun.com>
Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
make handles suffix-rules differently from GNU make.
* bin/Makefile.am (SUFFIXES, .in): Remove.
(autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
Move the body of the old .in rule here.
2002-09-16 Akim Demaille <akim@epita.fr>

Reported by Ralf Corsepius.
* lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.

reference to `struct timezone' in the description of
AC_HEADER_TIME.
2002-09-13 Akim Demaille <akim@epita.fr>
Version 2.54.
* config/config.sub, config/config.guess: Update.
* Makefile.maint: Update from bits of the Coreutils 4.5.1.
* Makefile.am: Adjust.
2002-09-13 Akim Demaille <akim@epita.fr>
* lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
reading config.log when the compiler is rejected.
Suggested by Guido Draheim.
2002-09-13 Akim Demaille <akim@epita.fr>
* bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
(chdir_init) might hang when stat'ing mounted directories.
Reported by Vance Shipley.
2002-09-12 Akim Demaille <akim@epita.fr>
* bin/autoscan.in (&parse_args): Pass a reference to the lists, not
the lists.
2002-09-12 Akim Demaille <akim@epita.fr>
* doc/autoconf.texi (Defining Symbols): Present two different
prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
difference between 1 argument calls, and 2-3 argument calls.
2002-09-12 Peter Eisentraut <peter_e@gmx.net>
* doc/autoconf.texi: Review grammar and punctuation.
2002-09-11 Paul Eggert <eggert@twinsun.com>
* doc/autoconf.texi: Fix minor formatting, spelling, and
grammatical typos.
(Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
is obsolescent.
2002-09-11 Akim Demaille <akim@epita.fr>
* doc/autoconf.texi (Questions): Rename as...
(FAQ): this.
(Defining Directories): New.
2002-09-09 Akim Demaille <akim@epita.fr>
* doc/autoconf.texi (Making testsuite Scripts): Update.
Suggested by Nishio Futoshi.
2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>

plain `@' is wanted.
2002-09-09 Akim Demaille <akim@epita.fr>
* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
`duplicates', since the algorithm was too naive and could keep
`--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
keep `--prefix foo --prefix bar' as `--prefix foo bar'.
Reported by Ralf Corsepius.
* tests/torture.at (Configuring subdirectories): Exercise these
cases.
2002-09-09 Akim Demaille <akim@epita.fr>
* lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
looking for a replacement file.

2002-09-06 Akim Demaille <akim@epita.fr>
* doc/autoconf.texi (Setting Output Variables): Clarify what
precious variables are.
Suggested by Pontus Skoeld.
2002-09-05 Akim Demaille <akim@epita.fr>
* bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
(ifnames, autoscan, autom4te): Since we don't only depend on
configure.ac variables (such as VERSION etc.), but also on prefix
and so forth, depend on Makefile, not configure.ac.
Reported by Alexandre Duret-Lutz.
* doc/autoconf.texi (Installation Directory Variables): Adjust.
2002-09-05 Kevin Ryde <user42@zip.com.au>
* doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
doesn't seem to be confined to ia64, just say "some versions".
2002-09-04 Akim Demaille <akim@epita.fr>
* Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
Automake 1.6c.
* Makefile.am (maintainer-clean-local): Remove.

example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
Brinkmann.
2002-09-03 Akim Demaille <akim@epita.fr>

* Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
as of today, on Automake's team suggestion.
2002-09-03 Akim Demaille <akim@epita.fr>
Version 2.53c.
2002-09-02 Akim Demaille <akim@epita.fr>
* bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
SITE_MACRO_DIR.
* configure.ac: Disable SITE_MACRO_DIR.
2002-09-02 Jim Meyering <meyering@lucent.com>
* doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
Also, tweak grammar: s/make sure to/be sure to/.
2002-09-02 Paul Eggert <eggert@twinsun.com>
* doc/autoconf.texi (Limitations of Builtins): Explain why logical
directory names are generally preferable to physical names.
2002-09-02 Akim Demaille <akim@epita.fr>
* lib/Autom4te/General.pm (&update_file): s/die/error/.
Reported by Raja R. Harinath.
* bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
* bin/autoupdate.in: Use error instead of die.
2002-09-01 Paul Eggert <eggert@twinsun.com>
* tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
ordinary shell concatenation rather than echo+tr+sed command that
runs afoul of a long-line-related sed bug in Solaris 8.
* bin/autoheader.in (parse_args): --warning -> --warnings.
* bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
stdout, as traditional "ls" does.
* lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
_AC_COMPILER_EXEEXT_O): Likewise.
* doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
* bin/autoconf.as: Add --prepend-include option. This patch was
applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
but bin/autoconf.in is generated automatically from bin/autoconf.as.
* bin/autoconf.in, configure: Regenerate.
* doc/autoconf.texi (Special Shell Variables): Mention
ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
MAILPATH and set PS1, PS2, PS4 to default values, to work
around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
For LC_ALL etc, first try to set to "C" as POSIX requires and as
the Autoconf documentation specifies; fall back to "unset" only if
this fails. Use a shell for-loop for this rather than an m4 loop,
to shorten the output script.
2002-08-30 Paul Eggert <eggert@twinsun.com>
* doc/autoconf.texi (Special Shell Variables): Mention POSIX
1003.1-2001's requirements for CDPATH. Give a simpler workaround
for the CDPATH problem. Document PWD.
(Limitations of Builtins): Document the problem that "cd $foo" and
"ls $foo" may refer to different directories in shells conforming
to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
example, since the old example is now out of date.
* lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
FOO" and "ls FOO" talk about different directories; this catches
problems when POSIX 1003.1-2001 "cd" fails due to symlink
spaghetti.
* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
of rolling our own unset.
(_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
in practice we needn't worry about CDPATH if unset doesn't work.
* Makefile.in, aclocal.m4, bin/Makefile.in,
config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
tests/Makefile.in: Regenerate with Automake 1.6.3.
* config/config.guess, config/config.sub, config/mkinstalldirs:
Update.
* configure: Regenerate with self.
2002-08-30 Kevin Ryde <user42@zip.com.au>
* doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
default output.
2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
* bin/autom4te.in (Request::load): Correctly test for "do" read
failure.
2002-08-29 Akim Demaille <akim@epita.fr>
* lib/Autom4te/General.pm (&xqx): New.
(&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
hand, which is not portable.
(&error): New.
* bin/autom4te.in: Use them.
Use &error instead of die.
* tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
Adjust.
2002-08-17 Paul Eggert <eggert@twinsun.com>
* lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
default list of compilers to try, since it was long ago superseded
by the ksh fc builtin. Suggested by Steven G. Johnson.
2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
* doc/autoconf.texi (Invoking autom4te): End the option table,
fixing a bug introduced by the previous patch.
(Limitations of Make): Add a 'target lookup' subentry in the
'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
2002-07-29 Mark D. Roth <roth@feep.net>
* bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
options and use $AUTOM4TE_PATH.
* doc/autoconf.texi: Remove documentation of autom4te
--include-envvar and --site-macro-subdir options and document
use of $AUTOM4TE_PATH.
* lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
arguments from each language section.
2002-07-29 Paul Eggert <eggert@twinsun.com>
* doc/install.texi: Include copyright symbol in copyright notice.
* Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
Replace with:
(AM_MAKEINFOFLAGS): New macro.
* doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
* Makefile.am (INSTALL): Use the new macros.
Use -o rather than --output, since "missing" does not grok --output.
2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
* doc/autoconf.texi (Limitations of Make): Escaped newlines in
comments do not always work. Never trust the exit status of
`make -k'.
2002-07-24 Kevin Ryde <user42@zip.com.au>
* doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
2002-07-23 Paul Eggert <eggert@twinsun.com>
* lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
apparently treats PATH="nonexistent" as if it contained ".".
Bug reported by Stefan `Sec' Zehl.
2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
* doc/autoconf.texi (Limitations of Make): Mention the special
handling of the obj/ directory by BSD make.
2002-07-20 Kevin Ryde <user42@zip.com.au>

This improves on an earlier suggestion by H. Peter Anvin.
2002-05-16 Paul Eggert <eggert@twinsun.com>
AC_FUNC_FNMATCH now tests only for POSIX compatibility.
AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
Both macros now accept an optional source-dir arg.
New macro AC_GNU_SOURCE to define _GNU_SOURCE.
* NEWS: Document this.
* doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
* lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
(AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,

reverting to 2.13-compatible behavior.
Add new optional argument DIR.
(AC_FUNC_FNMATCH_GNU): New macro.
* lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
2002-05-08 Paul Eggert <eggert@twinsun.com>
* lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
and it causes a 'test' syntax error if it fails.
Bug reported by Stephen Gildea.
* lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
If prototypes are supported, use them to check this at compile-time,
instead of trying to check it at run-time. If we must do a run-time
check, assume that setvbuf is standard when cross-compiling, as
nonstandard setvbuf occurs only on ancient and unlikely hosts.
Bug reported by Paul D. Smith.
* lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
argument specifying location of getloadavg.c. This removes a
FIXME. This idea was taken from Jim Meyering's implementation in
textutils.
* doc/autoconf.texi (Particular Functions): Document this.
Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
that's what the code does; this fixes a bug reported by
Paul D. Smith.
2002-05-03 Akim Demaille <akim@epita.fr>
* bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
autopoint instead of gettextize.

2002-04-29 Paul Eggert <eggert@twinsun.com>
* bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
files to be 1 second older; just set them to be the same time.
Also, sleep 1 second after the first aclocal, to work around
problems with sub-second time stamps on the input files.
2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>

under node "Limitations of Builtins".
2002-04-29 Akim Demaille <akim@epita.fr>

running configure.
From Christian Cornelssen.
2002-04-29 Akim Demaille <akim@epita.fr>
* tests/m4sh.at (LINENO): If testsuite itself is rewritten because
of lack of $LINENO support, then the test will compare the $LINENO
in testsuite vs. the lineno in the test file. This is wrong, of
course.
Be sure to protect it.
Reported by Patrick Welche.
2002-04-25 Akim Demaille <akim@epita.fr>
* doc/autoconf.texi (Obsolete Macros): Typo.
Reported by Vladimir Volovich.
2002-04-25 Akim Demaille <akim@epita.fr>
* bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older

if some of its input are younger, make them older.
Suggested by Paul Eggert.
2002-04-25 Akim Demaille <akim@epita.fr>
* doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
DEFAULT diversion.
(_AC_INIT_PREPARE): Use them to log them.
(_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
(AC_SUBST, AC_SUBST_FILE): Instead of buliding the
_AC_SUBST_SED_PROGRAM, store the list of output files/variables in
_AC_SUBST_FILES and _AC_SUBST_VARS.

2002-04-24 Akim Demaille <akim@epita.fr>

* tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
From Aaron Ucko.
2002-03-19 Akim Demaille <akim@epita.fr>
* bin/autoscan.in (scan_file): Specify the location in `&used'
invocations.
From Nicolas Joly.
2002-03-19 Akim Demaille <akim@epita.fr>

2002-03-19 Akim Demaille <akim@epita.fr>
* lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
2002-03-18 Paul Eggert <eggert@twinsun.com>
* doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
(Limitations of Usual Tools): Add mkdir section.
* lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
(AS_MKDIR_P): Require it. Use mkdir -p if available, falling
back on AS_DIRNAME to compute prefixes otherwise; this is
roughly what mkinstalldirs does. That way, we need not have
our own filename disassembler. The old disassembler did not
work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
* lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
Create at_test_all by a series of assignments,
not by a single assignment of a long string. The latter causes ksh
version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
presumably because of a buffer overrun.
2002-03-14 Paul Eggert <eggert@twinsun.com>
* lib/autotest/general.m4 (at_times_skip):
Renamed from at_times. Now a boolean.
ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
says 'times: not found'.
2002-03-14 Akim Demaille <akim@epita.fr>

2002-03-08 Akim Demaille <akim@epita.fr>

affect the latter.

* doc/autoconf.texi (Transforming Names): Equality between target

backward compatibility hooks. Rather, collect them all into...

* doc/install.texi (System Type): Ditto.
* lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
that `--host' implies cross-compilation.
2002-03-04 Akim Demaille <akim@epita.fr>
* doc/autoconf.texi (Evaluation Macros): New.
* lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
useless.
(_m4_foreach): Define the variant with immediate evaluation so
that it contains exactly the items, not an expression which
evaluation is the current item.
(m4_re_string, m4_re_word): Don't over quote them.
2002-03-04 Akim Demaille <akim@epita.fr>
Instead of having stacking `shift's evaluated at the end, let
`foreach' loops immediately evaluate them.
* lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
$*. This is the n-th time I change my mind, but hopefully this is
the last...
(m4_lquote): New.
(m4_text_wrap): Use m4_foreach, which is finally correct _and_
efficient.
(m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
it was only a hack for m4_text_wrap.
(m4_car2): Remove, replaced by...
(m4_cdr): New.
(_m4_foreach): Adjust.
* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
m4_bpatsubst for clarification.

cross-compilers, too. This undoes some of the most recent change
to this file.
2002-02-05 Akim Demaille <akim@epita.fr>
* tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

2002-02-05 Akim Demaille <akim@epita.fr>

optional are the sum of the previous files on the command line'.

needs an argument.
2002-01-28 Akim Demaille <akim@epita.fr>
* lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
AUTOTEST_PATH *after* it was set.
Don't put `.' in the PATH: the user should be precise and `./' if
needed. In addition, given that the test suite does some `cd', if
`.' is in the path, the `tested programs' sections will report
programs found in the test suite's directory, while during the
tests (performed in their own directory), these programs are no
longer visible. In other words, the results is confusing and
useless.
* tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

* doc/autoconf.texi (Installation Directory Variables): Englishoes
spotted by Jim Meyering.
2001-11-16 Paul Eggert <eggert@twinsun.com>
This patch implements a `long double' suggestion by Oliver Kiddle.
* lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
static, to catch errors if the value isn't known at compile-time
and the compiler supports dynamic arrays. Change its name from
`_array_' to `test_array' to avoid potential name clashes.
(AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
test. Do not define HAVE_LONG_DOUBLE if `long double' is no
better than double. Catch a bug in GCC 2.95.2 x86.
* doc/autoconf.texi (C Compiler): Document the above.

group, go back to the initial directory, not to at_suite_dir.

(AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
(AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
option.
(AT_CHECK_CONFIGURE): Use absolute paths.
(_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
The problem is still the old one: there is no means in M4 (that I
know about) to create a defining macro, because there is no means
to create `$1' etc., therefore, the defining macro ``swallows''
all the arguments meant to the defined macro.
2001-11-13 Akim Demaille <akim@epita.fr>

(AT_CHECK): Use them.
2001-11-13 Akim Demaille <akim@epita.fr>
* lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
in PATH.
Create `testsuite.dir/003/run' instead of `testsuite.003'.
Do it as soon as a test fails, don't wait till the end of the test
suite.
Don't remove $as_me.[0-9]*, since these files no longer exist.
2001-11-13 Akim Demaille <akim@epita.fr>
* tests/tools.at: Use absolute paths, since we are no longer run
in place.
2001-11-13 Akim Demaille <akim@epita.fr>
Now that tests are running in their own private dir, there is no
need to list the files to remove at the end of tests groups.

(AT_CLEANUP, AT_DATA): Simplify.

Remove the group dir if !debug && !failed.
* tests/atspecific.m4: Adjust.
2001-11-13 Akim Demaille <akim@epita.fr>
Start a new layout for Autotest: `testsuite' creates
`testsuite.dir' in which the at-check-line etc. files are to be
found, and `testsuite.dir/003' where the test group 3 is run.
* lib/autotest/general.m4 (AT_INIT): at_tests_dir,
at_check_line_file, at_format, at_test_normalized, at_group_dir
are new variables.
Create the directories.
Use absolute paths for at- files.
(AT_CHECK): Adjust.
2001-11-11 Michael Matz <matz@kde.org>

with stricter rules on LIBOBJS.
2001-11-12 Paul Eggert <eggert@twinsun.com>
* lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
* doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
__PROTOTYPES too.
2001-11-12 Akim Demaille <akim@epita.fr>
* lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.

From Jim Meyering.
2001-11-12 Akim Demaille <akim@epita.fr>
* lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
definition used by Automake where LEX is +/- "${missing} lex" and
`missing' itself contains variables.
2001-11-12 Akim Demaille <akim@epita.fr>
* lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
Now that M4sh pushes BODY, the comments were output at the end of
the test suites.
2001-11-08 Akim Demaille <akim@epita.fr>
* bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
that we can trace macros from aclocal.m4.
Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
obsoleted, and redirect to the former anyway.
Reported by Ralf Corsepius.
2001-11-08 Akim Demaille <akim@epita.fr>
* bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
processed only if present.
* tests/torture.at (Configuring subdirectories): Use autoreconf
instead of successive calls to autoconf.
Add a nonexistent subdirectory to exercise the patch above.
Reported by Ralf Corsepius.
2001-11-08 Kevin Ryde <user42@zip.com.au>

File::Spec.
Use and export them.

* bin/autoreconf.in (&parse_args): Trim the configure.ac part of
the arguments.
Default @ARGV to `.', not find_configure_ac.

Don't look for aclocal flags if we already know aclocal is not
used.
Move aclocal.m4t only if it exists.
Reported by Ezra Peisach.
2001-11-03 Akim Demaille <akim@epita.fr>
* bin/autoreconf.in (&parse_args): Work only on the configure.ac
passed on command line, defaulting to ./configure.ac if present.

* config/config.guess, config/config.sub, doc/standards.texi:
* config/lispdir.m4: Update from masters.
* configure.ac: Bump to 2.52f.
2001-11-02 Akim Demaille <akim@epita.fr>
* bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
Don't run aclocal when aclocal.m4 is not from aclocal.
From Ezra Peisach.
Don't run libtoolize and gettextize if --install is not given.
2001-11-01 Paul Eggert <eggert@twinsun.com>
* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
be invoked before _AS_LINENO_PREPARE.
(_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
than character ranges.
* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
invoking AS_BASENAME. Set the locale variables to 'C' if
possible, as POSIX requires this to get the traditional
behavior.
* doc/autoconf.texi (Special Shell Variables): Describe the above.
2001-10-31 Paul Eggert <eggert@twinsun.com>
* lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
with {}, as that triggers a bug in Bash 2.05.
(_AS_LINENO_PREPARE): Use Sed rather than
Awk. Fix the sed prepass to work even if there are multiple
instances of $LINENO on the same line. Do not substitute for
other variables like $LINENOT. Do not check file dates; such a
check is unreliable on sufficiently fast machines, and removing
the check makes the code simpler and more reliable. Check for
output and chmod failures.
* doc/autoconf.texi (Special Shell Variables): Document
the above.
2001-10-31 Akim Demaille <akim@epita.fr>
* tests/Makefile.am (atconfig): Remove this target, Automake
handles it now.
2001-10-31 Akim Demaille <akim@epita.fr>
* lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
provided, while it is optional.
* configure.ac: Adjust.
2001-10-26 Paul Eggert <eggert@twinsun.com>
* NEWS, README, configure.ac, lib/Autom4te/General.pm,
lib/Autom4te/Struct.pm:
Require Perl 5.005_03 instead of just 5.005, as some tests fail
with 5.005_02.
* doc/autoconf.texi (Special Shell Variables): Document some
more LINENO gotchas, particularly with respect to the Awk+Sed hack.
* lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
(_AS_LINENO_PREPARE): Use it instead of shell eval, since
eval $LINENO is not portable in practice.
2001-10-24 Akim Demaille <akim@epita.fr>
* lib/Autom4te/General.pm (backname): New.
2001-10-24 Akim Demaille <akim@epita.fr>

2001-10-22 Paul Eggert <eggert@twinsun.com>
* lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
POSIX decided to standardize on the int flavor of strerror_r.
Always do char* test, as there's no reason not to.
Assign to a char* var, to catch strerror_r that returns int*.
* doc/autoconf.texi (Particular Functions):
Document the above changes. Also, document the fact that
AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
* NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
2001-10-20 Akim Demaille <akim@epita.fr>
* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

2001-10-20 Akim Demaille <akim@epita.fr>
* bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
Remove, dead.

(AS_BASENAME_EXPR): New macro.
(AS_BASENAME_SED): Do not assume GNU sed semantics.
(AS_BASENAME): Use 'basename' if that works; then try 'expr';
and fall back on 'sed' only if the other two fail. This makes
AS_BASENAME act more like AS_DIRNAME.
(as_me): Shell-quote the argument of AS_BASENAME, in case $0
contains white space.
* lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
Use AS_DIRNAME, since I think it's now DOS-friendly.
* tests/m4sh.at (DIRNAME_TEST): New arg $3.
Allow "dirname //FOO" to return either / or //, as POSIX allows
either behavior.
2001-10-10 Akim Demaille <akim@epita.fr>

* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
combination of Awk and sed to replace $LINENO.
2001-10-02 Paul Eggert <eggert@twinsun.com>
* doc/autoconf.texi (Limitations of Builtins): You can't use
"source"; it's not portable. Remove confusing and
somewhat-incorrect example involving "." and "/".
* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
compatibility with POSIX shells.
2001-10-02 Akim Demaille <akim@epita.fr>

Various small adjustments.
2001-10-01 Akim Demaille <akim@epita.fr>

Always use `$' as shell prompt.
2001-09-30 Paul Eggert <eggert@twinsun.com>
* lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
Don't use nested parenthesization. This patch was originally
suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
but somehow it didn't get incorporated then.
* doc/autoconf.texi (Limitations of Usual Tools):
Clarify remark about sed and nested parenthesization.
* lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
Report an error if the size cannot be determined even though
the type exists.
* lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
Check for `expr' arithmetic overflow, and for compilation failure,
and invoke a new argument $4 if either is discovered.
This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
(_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
2001-09-28 Akim Demaille <akim@epita.fr>

* tests/fortran.at (GNU Fortran 77): there.
* doc/autoconf.texi (autoconf Invocation): Fix the example:
AC_TRY_RUN is about compilation, not shell commands.
(Test Programs): AC_TRY_RUN works as used to be advertised.
2001-09-27 Akim Demaille <akim@epita.fr>
* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
Raja R Harinath:
Be sure to detect when $LINENO always returns the same value.
Look for the original script, basename($0) is certainly not

* lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
Do not pass a first argument with leading '-'

now merely checks whether it is an error to pass an argument
to getpgrp.
* lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
(AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
whether it is a (compile-time) error to pass an argument to

* tests/base.at: Fixed the expected responses. The old ones were
one line out...
* lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as

* lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
Always include <stdio.h> and <stdlib.h>. Evaluate
the expression in an extra function before these includes. Call
fprintf "%d" only after ensuring the argument is of type 'int'.

2001-09-17 Paul Eggert <eggert@twinsun.com>
Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
or CFLAGS=-O5. In that case, the linker has a relaxed view of
fatal errors, and AC_CHECK_LIB causes it to include libraries even
when they don't exist.
* lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
need it.
* lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
version with the version used by fileutils 4.1, except use
AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if

* tests/atspecific.m4, tests/tools.at: Passing --localdir is
indeed related to running the test suite, while passing

2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
* tests/semantics.at (AC_C_BIGENDIAN): New test.
2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
* lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
* doc/autoconf.texi (C Compiler Characteristics): Update
documentation for AC_C_BIGENDIAN.
2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
* lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
magic values from an object file when cross-compiling.
Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
2001-08-10 Akim Demaille <akim@epita.fr>
* bin/autom4te.in (&handle_output): Don't use `grep' with side
effects.
Suggested by Russ Allbery.
2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
current $prefix to the sub-configures.
2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>

extension (needed on BeOS). Reported by Guido van Rossum.
2001-08-09 Akim Demaille <akim@epita.fr>
* bin/autom4te.in ($icache): Load it only if older than autom4te.
2001-08-07 Akim Demaille <akim@epita.fr>
* lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
removed.
(at-setup-line): Huh? Be a variable `at_setup_line', not a file.
No need to remove the files before and after the each test, before
each test and at the end of the suite is enough.
Display only the children `times', not the shell's.
If the test failed or was skipped, at-times is not available.
2001-08-07 Akim Demaille <akim@epita.fr>
Always produce testsuite.log, including when there are no
failures. This helps getting information on skipped tests, and
duration of the tests. Err, implement the latter btw.
* lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
Dump information on the first run of each test.
(AT_CLEANUP): Create `at-times' containing the duration of the
test group.
2001-08-07 Akim Demaille <akim@epita.fr>
The use of `dumpstat' revealed that `len' was used although it
should not. m4_text_wrap was using it, but in the Autoconf world
where it is legal. Hence (i) test M4sh in its own world, not
Autoconf's, and (ii), ahem, fix the bug :)
* lib/autotest/general.m4: Be sure the set good quotes, as tracing
does not like `' instead of [].
(AT_INIT): Forbid `^_?AT_'.
And don't output such tokens.
* tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
`script.as', and `autom4te.cache'.
Remove `empty' and `macro' which are no longer used.
* tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
* tests/m4sugar.at: Use it.

AC_TRY_LINK.
* lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.

(AC_F77_MAIN): Likewise.
2001-08-04 Akim Demaille <akim@epita.fr>
Don't rely on M4sugar outputting the patterns in files, since we
might process the output _without_ running m4, hence without these
files.
* lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
* bin/autom4te.in (@Request::includes): Remove, unused.
(@Request::source): Rename as...
(@Request::input): this.
(@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.

(&handle_m4): M4sugar no longer wants `m4_tmpdir'.
(m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
2001-08-04 Akim Demaille <akim@epita.fr>
`autoconf && autoheader' is sped up. Now, speed up `autoheader &&

2001-08-04 Akim Demaille <akim@epita.fr>
* bin/autom4te.in ($force): New.
(&parse_args, &print_usage): -f, --force is a new option.
(&handle_output): CPP directives might have spaces after `#'.
(&parse_args): The first file only can be frozen.
2001-08-04 Akim Demaille <akim@epita.fr>
Don't let autom4te compute the `include' traces several times:
first check that the trace cache file is up to date, and then
compare its timestamp with that of the output.
* bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
the preamble. Don't require 5.005 as Autom4te::General does it,
and better yet (use `use', not `require'!).
* lib/Autom4te/Struct.pm: Rename the last occurrences of
Class::Struct as Autom4te::Struct.
* lib/Autom4te/General.pm (File::stat): Use it.
(&mtime): New, export it.
* bin/autom4te.in: Use it.
Declare `$req' is invalid if it is outdated.
Don't declare it valid before saving it if something went wrong.

* tests/tools.at (autoconf: forbidden tokens, basic)
