2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
$ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
* tests/tools.at (autoconf: subdirectories): New test, taken from
the corresponding problem report by Ralf Wildenhues in:
http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
* lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
Quote some uses of shell variables if they might suffer unexpected
globbing. This doesn't fix all instances of quoting problems that
I found, just the easy ones that look safe.
* lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
(AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
(AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
(AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
* lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
* lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
* lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
Likewise.
* lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
* lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* bin/autoreconf.in ($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
`$*' and IFS concatenation issue with traditional shells and
bash-2.04. Report by Seanster@Seanster.com.
2006-05-03 Bruno Haible <bruno@clisp.org>
* doc/autoconf.texi (Limitations of Usual Tools): Identify more
precisely which Mac OS X versions have the od problem.
2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi: Use @option systematically.
(Integer Overflow):
2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
and Bruno Haible <bruno@clisp.org>
* doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
about 'od'.
(Integer Overflow): Mention the special case of integer division
overflow.
2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
traditional shells like the Solaris one that do not use the
first IFS character for assembling `$*'.
Prompted by a related report from autoconf_bug@nro.ca.
2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
Mention more problems with the -e option.
2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* NEWS: Typo.
* doc/autoconf.texi (Systemology): Mention the Heirloom Project.
* doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
in URLs to improve DVI formatted output (requires texinfo 4.6).
(System Services, Systemology, Shellology): Likewise.
(Limitations of Usual Tools): Rewrite Mac OS X example for nicer
output.
* doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
continuous text.
(Runtime): Fix macro argument names to match description:
`action-if-found' -> `action-if-true' and similarly.
(Obsolete Macros): Likewise.
* lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
(AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)

/bin/sh set unsorted output.
* lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
* tests/local.at: Likewise.
2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
(Integer Overflow, Null Pointers, Buffer Overruns):
(Floating Point Portability, Exiting Portably): New sections.
(Writing Test Programs): Fix some langauge. Recommend exiting
with status 1, not merely nonzero. Clarify exit declaration.
(Run Time): Move C exit status stuff to new Exiting Portably section.
(Systemology): Mention Posix and levenez. Update v7 reference.
(Portable Shell): Mention the Posix shell.
2006-04-25 Stepan Kasal <kasal@ucw.cz>
* bin/autoconf.as (me): Replace by as_me.
2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
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.
* doc/autoconf.texi (Programming in M4sh): Comment out the
documentation of AS_BASENAME, for now.
(Shell Substitutions): Do not use AS_DIRNAME in an example.
(Limitations of Builtins) <basename>: Do not refer to
AS_BASENAME.
* bin/autoconf.as (me): Don't use AS_BASENAME.
(dir): Remove the unused variable.
* lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
AS_DETECT_REQUIRED. All uses changed.
(_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
All uses changed.
(_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
(AS_BASENAME): Use "basename --" to protect against leading "-".
(_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
(_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
(_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
(_AS_DIRNAME_PREPARE): Likewise.
(_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
(_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
(AS_DIRNAME): Use "dirname --".
2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
of "run time" and "run-time" changed to "runtime", for consistency.
* lib/autoconf/fortran.m4: Likewise (in comment).
* lib/autoconf/functions.m4: Likewise.
* lib/autoconf/general.m4: Likewise.
* lib/autoconf/headers.m4: Likewise.
* doc/autoconf.texi (Run Time): Document the exit status situation
with more accuracy and detail.
2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* 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>
* NEWS: Update.
* configure.ac (AC_INIT): Bump to 2.59d.
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>
Import macros from gnulib (often changing their name).
* NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,

The manual mentions Gnulib more prominently.
* doc/autoconf.texi (Gnulib): New node.
(Pointers): Add Gnulib URL.
(Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
(Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
Gnulib section.
(Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
suggest a #define rather than a typedef for _Bool, and mention
Gnulib rather than trying to substitute stdbool code.
(Generic Headers): Add AC_CHECK_HEADERS_ONCE.
(Generic Declarations): Add AC_CHECK_DECLS_ONCE.
(Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
AC_STRUCT_DIRENT_D_TYPE.
(Particular Types): Mention stdint.h and inttypes.h as standard
headers too.

* doc/autoconf.texi (Programming in M4sh): Document that
AS_MKDIR_P exits the script on failure.
* lib/autotest/general.m4: Remove redundant AS_ERROR.
2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

Paul Eggert <eggert@cs.ucla.edu>,
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.

(AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
* doc/autoconf.texi (Shell Substitutions): Mention the MSYS
shell issue with double-quoted command substitutions of native
commands.
Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
Marshall.

_AC_PRESERVE_HELP_ORDER, ...
(AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
* lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
inside m4_expand_once; it is redundant.

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

2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
* tests/mktests.sh: Don't use 'cat'; just read the files directly.
Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
Use 'comm' rather than N instances of grep; this also fixes a bug
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.
Use awk rather than grep -E or egrep, to avoid

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 filei 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...

2006-04-01 Stepan Kasal <kasal@ucw.cz>
* bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
switch all of them on and of when necessary. Fixes the bug when
m4sugar macros (e.g., m4_define) were expanded after the first

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.
* tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
parameters.
2005-07-10 Stepan Kasal <kasal@ucw.cz>
* lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
versions of Portland Group compiler produce single- and double-quoted
-cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>

ac_cv_build_alias to ac_build_alias.
(AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
change eliminates it. Problem reported by Alexandre Duret-Lutz.
* lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
(AC_ARG_VAR): ... here.
(_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
target_alias.
Keep a list of all precious variables and process them with one simple
for loop, instead of expanding all commands, or, OTOH, complicated
processing of output of "set".
* lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
variable names in new macro...
(_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
(_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
a loop to assign all ac_env_* and ac_cv_env_* variables.
(_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
to INIT_PREPARE.
(_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
its value to shell variable ac_precious_vars and call
_AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
_AC_ARG_VAR_VALIDATE.
* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

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.

* lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
* doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
swallow records with more than 99 fields.
* lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
parse the long line.
2005-06-04 Stepan Kasal <kasal@ucw.cz>
* doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
swallow literals longer than 399. Reported by Ralf Wildenhues.
* lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
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).
(DISTCLEANFILES): Remove $(check_SCRIPTS).

2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
* lib/autotest/general.m4 (AT_INIT): Don't create a regular
expression of unbounded size when processing the --list
option. This runs afoul of a limit of 399 bytes per regular
expression on AIX. Problem reported by Ralf Wildenhues.
2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
* NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.

give all the details about |#_!!_#|.
Reword description of line replacement.
2005-05-31 Dan Manthey <dan_manthey@partech.com>
* 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>
* tests/local.at: Don't attempt to check for negated character
classes in shell scripts. The test was too brittle.
2005-05-25 Stepan Kasal <kasal@ucw.cz>
* bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
* doc/autoconf.texi (Limitations of Builtins): Document this
limitation.
2005-05-24 Stepan Kasal <kasal@ucw.cz>
* lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
common code; used in many places in the tree.
(AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
(_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
* lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
* lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
messages when ac_unique_file is not found.

* bin/Makefile.am: Merge the two rules for creating scripts.
2005-05-23 Stepan Kasal <kasal@ucw.cz>
* lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
obsolete; it was never documented.
(AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
2005-05-20 Stepan Kasal <kasal@ucw.cz>
* NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
* lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
(ac_top_builddir): ... this ...
(ac_top_build_prefix): ... to this; the old name is also kept, for
backward compatibility.
(ac_top_builddir_sub): New variable, without the trailing slash,
always nonempty.
(_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

of confdefs.h .
2005-05-17 Stepan Kasal <kasal@ucw.cz>
* lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
argument to m4_foreach. I guess it was necessary in the past,
but I think it's a no-op now.
2005-05-17 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.''
* lib/autoconf/status.m4: On various places, use expr instead of
``echo|sed.''
(_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
(_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
* lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
a range.
* tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
the wrong patterns between ``case'' and ``esac.'' The previous
code had false positives.
2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
* lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
as on 2005-05-02.

abbreviations of --version and --debug.
2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Autoconf Language): Be more precise about
quoting rules. Problems noted by Stepan Kasal.
Also, throughout this document, be more careful about white space.
"blank", "white space", and "space" all have different meanings
and we should be careful to say what we mean.
2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
Fix C++ related problems reported by Werner Lemberg.

* lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
avoid problems with C++ and throw.
* tests/compile.at: .cpp, not .cc.

2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* doc/autoconf.texi (Generic Functions): Typos.
2005-05-02 Gary V. Vaughan <gary@gnu.org>
* lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
set by latest automake.
2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
outputs 0 on GNU/Linux these days.
2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Autoconf Language): Add more description
about quoting heuristics.
(Limitations of Builtins): Describe "set -" problems.
2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
not newline.
* doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
by AC_DEFINE; it was a mistake.
From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
2005-04-25 Stepan Kasal <kasal@ucw.cz>
* lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
2005-04-22 Stepan Kasal <kasal@ucw.cz>
* doc/autoconf.texi (External Software): Quadrigraphs are not
processed correctly in AS_HELP_STRING; avoid this in the examples.
* lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
* lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
comment and reduce m4_default([foo], []) to [foo].
(m4_strip): Update the explanation.
2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
Remove core.conftest.* too; it's generated by Tru64 5.1.
Problem reported by Jennis Pruett.
* lib/autoconf/functions.m4
(AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
Don't bother to remove core files; AC_RUN_IFELSE should do that
for you.
2005-04-19 Stepan Kasal <kasal@ucw.cz>
* lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
* lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
Report from Horst Wente.
2005-04-15 Stepan Kasal <kasal@ucw.cz>

examples showing how to implement --with-* and --enable-* options.
2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
as well as configure.in. Problem reported by Gregorio Guidi.
2005-04-10 Paul Eggert <eggert@cs.ucla.edu>

2005-04-01 Stepan Kasal <kasal@ucw.cz>
* doc/autoconf.texi (Generic Programs): Fix a typo.
2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
* lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
fails if %s isn't supported. Problem reported by Ralf Wildenhues.
2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
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 "\".
* doc/autoconf.texi (Installation Directory Variables): Allow
"," in file names. Do not use \@; it's not a portable regexp.
* bin/Makefile.am (edit): Likewise.
* lib/Makefile.am (edit): Likewise.
* tests/Makefile.am (edit): Likewise.
* tests/semantics.at: Likewise.
* tests/torture.at: Likewise.
* lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
* lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
* doc/autoconf.texi (File System Conventions): Warn about
unportable file names.
* lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
(AC_INIT): Use it.
(_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
ac_pwd, and quote srcdir.
* lib/autotest/general.m4 (AT_INIT): Quote file name args.
* doc/autoconf.texi: Fix some systematic formatting problems.
".)" 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>
* doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
argument is often called 'build-aux'.
2005-03-07 Stepan Kasal <kasal@ucw.cz>
* doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
macro AC_TRY_LINK is obsolete.
(Installation Directory Variables): Change `AC_OUTPUT_FILES' to
`AC_CONFIG_FILES'.
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'.
* lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
* lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
* lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
* doc/autoconf.texi (File Descriptor Macros): New section.
(Printing Messages): Mention it.
* tests/base.at (Input/Output): New test.
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
from /dev/null, as "configure" shouldn't read stdin, and this
insulates us from problems (e.g., when testing for "cl").
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
"</dev/null" since it's now done at the top of 'configure'.
* lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
* lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
Also, replace grep with shell pattern-matching, to save a process.
2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
_AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
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>
* doc/autoconf.texi (Special Shell Variables): Clarify
PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi: Use @acronym for DJGPP.
Fix some @code's that should have been @env's, and vice versa.
Sort environment variable names.
Mention that shells no longer inherit IFS.
Don't recommend PATH_SEPARATOR=';' so strongly.
Mention that $RANDOM might expand to the empty string.
"symlink" and "soft link" -> "symbolic link".
Improve mktemp description (reported by Bruno Haible).
2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
* tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
* tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
Likewise.
* tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
Likewise.
2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
* NEWS: Mention AT_COPYRIGHT.
* 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).
2005-02-04 Noah Misch <noah@cs.caltech.edu>
and Paul Eggert <eggert@cs.ucla.edu>
* tests/autotest.at (Empty test suite): New test.
* tests/torture.at (Substitute and define special characters)
(Substitute a 2000-byte string, Define to a 2000-byte string)
(Substitute a newline, Define a newline): New tests.
2005-02-04 Noah Misch <noah@cs.caltech.edu>
* lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.

(AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
* tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
(Standard regular expressions): New test.
(m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
excess test name quoting.
* tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
CPPFLAGS to `configure' instead of setting it in `configure'.
* lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
on some platforms.
* lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
* tests/local.at (AT_CMP): New macro.
(AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
(AC_SAVE_STATE): Move environment grep...
(AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
(AT_CONFIG_CMP): New macro.
(AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
* tests/c.at (Extensions): Do not exit early.
* tests/atlocal.in: Inherit $GREP.
* lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
(_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
* lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
(AC_COPYRIGHT): Factor header comment portion out and move into...
* lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.

(AT_INIT): Add Autotest copyright notice. Display copyright notices in
--version output.

2005-02-04 Bruno Haible <bruno@clisp.org>
and Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
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.
(AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
space.
2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
* lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to

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.

stripping.

* lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
"char c = '\200';" rather than "char c = 0x80;" as the

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.
* bin/autoconf.as (autom4te_options): New var.
Use it instead of appending to AUTOM4TE, so that we can allow
spaces in the build directory's absolute name.
* bin/autoheader.in ($autoconf): Allow spaces in file names.
* lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
AT_CHECK_NOESCAPE): Likewise.

* doc/autoconf.texi (Function Portability): Document isinf and
and isnan. From a suggestion by Kevin Ryde.
* lib/Autom4te/General.pm (END): Return correct exit status even
if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
* tests/torture.at (Deep Package): Use configure.in, not configure.ac,
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.
(AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
* lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
* doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.

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>
* lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
_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,
etc. are read only. Problem reported by Ludovic Courtes.
2004-06-23 Noah Misch <noah@cs.caltech.edu>
* lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
zsh, disable GLOB_SUBST to avoid backslash handling problems.
(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).
* doc/autoconf.texi (Shell Substitutions): Spelling error reported by
Bob Proulx.
2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
* lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
by Jim Meyering.
2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
can be rewritten using if-then-else. Suggested by Bruno Haible.
2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
* doc/autoconf.texi (testsuite Scripts): Fix typo.
Problem reported by Stepan Kasal.
2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
* tests/Makefile.am (autoconfdir): Fix to match comment (trivial
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
consider -g to work if it generates warnings when plain compiles
don't. Problem reported by Braden McDaniel in:
http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html

reported by Jim Meyering in:
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>

* NEWS: New macro AC_CHECK_ALIGNOF.
* doc/autoconf.texi (Generic Compiler Characteristics): Document it.

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).

2004-01-15 Paul Eggert <eggert@twinsun.com>
* lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
-std1 disables some useful extensions on Tru64. Problem reported
by N. Lichtmaier in

2004-01-14 Paul Eggert <eggert@twinsun.com>

2004-01-09 Paul Eggert <eggert@twinsun.com>
* lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
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
`"'...'"`, as it's confusing (and I suspect it may not work on
some platforms). The code was incorrect anyway, as it assumed
that \$ evaluated to itself in that context. Reported by
Alexandre Duret-Lutz.
2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

2004-01-04 Paul Eggert <eggert@twinsun.com>

* doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
-c -o might not work. From a suggestion by Kevin Ryde.
(C Compiler, Generating Sources, Limitations
of Usual Tools, Limitations of Make, Making testsuite Scripts):
Don't put '-o' after non-options, as POSIX doesn't allow this.
Mention that cc's name might be gcc or c89 or whatever.
2004-01-04 Kevin Ryde <user42@zip.com.au>

explanation clearer.

them on the fly.
2003-11-24 Akim Demaille <akim@epita.fr>

The test suite are sometimes assigning timings incorrectly.
Reported by Henk Krus.
Diagnosed by Nicolas Joly.
* lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
AT_help_all.
Instead of making AT_help a sequence of assignments to grow
$at_help_all, just make AT_help_all be the growing contents of
$at_help_all, and make a single assignment in...
(AT_INIT): here.
(at_times_skip): Flip the meaning and rename as...
(at_times_p): this.
(AT_INIT): When summarizing the test that ran, remove
$at_times_file after use, and check it is present before trying to
use it.

Version 2.57d.
* bin/Makefile.am (edit): Handle '@configure_input@'.
(autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
(ifnames): chmod -w.
* tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
executables, not bin/ executables! Otherwise all the magic needed
to find non installed files is turned off. This caused a failure
of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
as found in its environment (sent by tests/autoreconf): pointing
to bin/autom4te that could not find its files.

Add support for newer Fortran dialects. The F77 interface is
unchanged, and continues to support Fortran 77. New FC macros
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
new macros AC_FC_SRCEXT to set the source extension, and
AC_FC_FREEFORM to accept free-form source files.

Output stack traces in warnings.
* lib/m4sugar/m4sugar.m4 (_m4_warn): New.
Replace the former...
(m4_warn): Pass the call stack to _m4_warn.

($help): Use Autom4te::ChannelDefs::usage.
* bin/autoscan.in: Use Autom4te::ChannelDefs.
* lib/Autom4te/General.pm: Don't export error: you don't own it.
2003-08-21 Akim Demaille <akim@epita.fr>
First stab at preserving warnings between calls to autom4te,
including when the cache is used.
There are still several issues: (i) there are too many runs of m4
(one for include, one for warnings, and some more), (ii) warnings
spreading on several lines are not handled gracefully, (iii) the
code meant to have the call stack display for errors does not work
(its handling should move from m4 to autom4te).
* bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
Use them.
(@preselect): Add m4_warn.
($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):

2003-08-20 Akim Demaille <akim@epita.fr>

* 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.

Paul Eggert <eggert@twinsun.com>
* 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.

From Ian Redfern.
2003-05-22 Paolo Bonzini <bonzini@gnu.org>
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.
* lib/autotest/autoconf.texi (testsuite Scripts): Update
the name of the debugging directory and information about
its contents.

to support the new --keywords behavior.

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>

Reported by Paul D. Smith.
2002-10-08 Paul Eggert <eggert@twinsun.com>

* doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
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>

* 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>

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>

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,

failure.
2002-08-29 Akim Demaille <akim@epita.fr>

hand, which is not portable.

* bin/autom4te.in: Use them.
Use &error instead of die.

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.

'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.

--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

Bug reported by Stefan `Sec' Zehl.
2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>

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.

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

* doc/autoconf.texi: Follow the outline suggested in the GNU
Sample Texts sections of the Texinfo 4.2 manual. Most

(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'.

* lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally

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

(m4_text_wrap): Use m4_foreach, which is finally correct _and_

it was only a hack for m4_text_wrap.
(m4_car2): Remove, replaced by...

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.

2002-01-06 Akim Demaille <akim@epita.fr>

configure.
* doc/autoconf.texi (testsuite Scripts): Adjust.

EXTRA_DIST it since its a source.
2002-01-06 Akim Demaille <akim@epita.fr>

of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
and PACKAGE_BUGREPORT from here...
(_AC_INIT_DEFAULTS): to here, since it is unrelated to the
arguments.
(_AC_INIT_PREPARE): AC_DEFINE these symbols.

trailing files, don't apply `-rf' to files which might not be

Suggested by Jonathan Kamens.
2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

2001-11-26 Akim Demaille <akim@epita.fr>
* bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
Remove $filepath, useless.
(&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
variables, they are really part of the tokens.
Split the input line on spaces and then look for tokens.
Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
because of `lex$U.$(OBJEXT)'.
(&scan_files): Use "@list" instead of join.
* doc/Makefile.am (CLEANFILES): Add *.fns.
2001-11-26 Akim Demaille <akim@epita.fr>

Before, having a line containing the opening of a multi line
comment made the whole line be ignored.
2001-11-26 Akim Demaille <akim@epita.fr>
* doc/autoconf.texi (Using an Autotest Test Suite): New.
(testsuite Scripts): Be one of its subsection.

top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
at_top_builddir.

top_srcdir, builddir and top_builddir.
Use `at_*dir' relatively to the directory containing the
suite, use `*dir' when relatively to the current group dir.
2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
* doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
lib/autoconf/functions.m4, lib/autoconf/headers.m4,

spelling errors.
2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
* doc/autoconf.texi (Using System Type): Add an example of `case
$host' usage so people quit using `case $target' everywhere.
2001-11-22 Akim Demaille <akim@epita.fr>
* 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.
* NEWS: Likewise.
2001-11-13 Akim Demaille <akim@epita.fr>
* tests/m4sh.at (LINENO): Protect from autom4te's substitution by
hand.
* tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
2001-11-13 Akim Demaille <akim@epita.fr>
* lib/autotest/general.m4 (AT_INIT): After having run the test
group, go back to the initial directory, not to at_suite_dir.
2001-11-13 Akim Demaille <akim@epita.fr>
* tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
(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>
* tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
(AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
configure.ac.
* tests/aclocal.m4: Remove, as it is no longer used.
2001-11-13 Akim Demaille <akim@epita.fr>
* lib/autotest/general.m4: Change `tests?' into `groups?' in
variable names when referring to a single test group, or to
`suite' when referring to the whole test suite.
`at_last_test' is removed: m4 compute at_format itself.
(at_stdout, at_stder1, at_stderr): New variables.
(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.
* lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
(AT_data_files, at_data_files): Remove.
(AT_CLEANUP, AT_DATA): Simplify.
(AT_INIT): Adjust.
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>
* m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
(m4_car2): New.
(m4_car): Properly quote arguments.
2001-11-13 Akim Demaille <akim@epita.fr>
* tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
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.
2001-11-12 Akim Demaille <akim@epita.fr>

specify to what the macro should be defined (typically to 1).
2001-11-12 Akim Demaille <akim@epita.fr>
* lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
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_name_is_absolute): New, wrappers around routines from
File::Spec.
Use and export them.
(&find_configure_ac): Optionally take a directory where to look at.
* 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.
(&maybe_autoreconf, File::Find): Remove, unused.
(&autoreconf): If autoconf is not used, don't try to trace.
2001-11-02 Akim Demaille <akim@epita.fr>

* 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>

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>

* bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):

(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.

enough.

now merely checks whether it is an error to pass an argument
to getpgrp.

(AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check

added test. It now correctly handles /1/2/3/, returning '3' not ''.

one line out...
* lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as

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.

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

2001-09-07 Akim Demaille <akim@epita.fr>
* bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
doesn't neutralize SIGINT, making autoconf etc. non interruptible.

* bin/autom4te.in: --language is -l, not -s.
2001-09-05 Akim Demaille <akim@epita.fr>
Be ready to handle filenames as stupid as `dnl.at', for if even
the maintainer is dumb enough to do that...
* lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
excellence in M4 quotation: consider `__file__' is active.
And BTW, when invoking m4, pass the --include in the right order:
the wrong one.

4m.
2001-09-05 Akim Demaille <akim@epita.fr>

2001-09-05 Akim Demaille <akim@epita.fr>
CVS GNU M4 doesn't like `undefine(undefined)'.
* bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
New, extracted from main.
Use IO::File wherever possible.
(input.m4): Be constant, use -I instead of hard coding $tmp.
Therefore be a quoted heredoc.
Don't invoke `_au_disable', since ac was not loaded, but just
`unm4.m4'.
2001-08-31 Akim Demaille <akim@epita.fr>
Version 2.52d.
2001-08-31 Akim Demaille <akim@epita.fr>

2001-08-31 Akim Demaille <akim@epita.fr>
* lib/Autom4te/General.pm (&find_file): Browse the includes in the
inverse order.
2001-08-31 Akim Demaille <akim@epita.fr>

to m4sugar was lacking!
2001-08-31 Akim Demaille <akim@epita.fr>
* man/Makefile.am (.x.1): We really have to pass
autom4te_perllibdir.
2001-08-31 Akim Demaille <akim@epita.fr>
* lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
debug scripts, in particular passing explicitly listed tests to
run is stupid.
2001-08-31 Akim Demaille <akim@epita.fr>
* bin/autom4te.in (&parse_args): Strip `.' from `@include'.
* bin/autoupdate.in: Use --include, -I, and --force, -f, too.

* bin/autoheader.in (%symbol): Strip arguments of macros.

* bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.

`print $out' doesn't print `$_' but `$out'.
* tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
(autoheader): Pass --force since the test suite goes too fast for
the time stamps.
Adjust to the new autoheader messages.
2001-08-31 Akim Demaille <akim@epita.fr>

Drop AC_MACRODIR dead for real.

* bin/autoheader.in: Rewrite in Perl.

2001-08-31 Akim Demaille <akim@epita.fr>

Map --localdir, --autoconf-dir onto it.
Forward autom4te's options instead of interpreting them.
* bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
There is no such envvar since the inception of autom4te.cfg.

* bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
* bin/autoscan.in, autoupdate.in: Use exclusively the name of the
installed peer executables, only PATH is allowed to resolve it.
Pass `autoconf_dir' via options, not via invisible envvars.
* lib/Autom4te/General.pm (&find_peer): Remove.
* lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
`abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
* man/Makefile.am: Let help2man rely on PATH instead of trying to
find the executables for it.
* tests/Makefile.am: Major cleanup. Too lazy to document...
* tests/atlocal.in: Remove all the obscure envvar manipulations.
We only need PERL.
* tests/atspecific.m4, tests/tools.at: Passing --localdir is
indeed related to running the test suite, while passing
--autoconf-dir and others is related to running non installed
Autoconf executables. So don't do that, leave it to...
* tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
* tests/autoscan: New.
* tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
refer to library files: rely on --language.

Suggested by Paul Eggert.
2001-08-29 Akim Demaille <akim@epita.fr>
* Makefile.maint (do-po-update): Wget refuses to overwrite files:
download in a tmp dir.
2001-08-29 Akim Demaille <akim@epita.fr>
* lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
case insensitive OSes out there :(

readable.
Adjust callers.

the name of the directory they're in, instead of the filename,
since version.m4 is now in m4sugar, but m4_acversion must not be
classified as an Autoconf macro.
($input_m4): Don't qualify the path to m4sugar.
Rather, pass autoconf_dir to m4.

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 $prefix to the sub-configures.
2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
* lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
extension (needed on BeOS). Reported by Guido van Rossum.
2001-08-09 Akim Demaille <akim@epita.fr>
* bin/autom4te.in ($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.
* lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
2001-08-07 Akim Demaille <akim@epita.fr>
* bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>

2001-08-04 Akim Demaille <akim@epita.fr>
* lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
(AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
AC_TRY_LINK.
* lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
* lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
(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_output): Fetch the patterns from the traces.
`$forbidden' and `$allowed' are constant: use m//o.
(&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 &&
autoconf', i.e., in addition to caching traces, cache the output.
* bin/autom4te.in (Request::cache): Rename as...
(Request::id): this.
($cache, $icache, $tcache, $ocache): New.
(&handle_m4): Save M4 output in the cache instead of $tmp.
(&handle_output): Adjust.
(&up_to_date_p): Check that the output cache is up to date too.
(top level): Run `&handle_m4' iff force or the cache is invalid.
Run `&handle_output' if the output cache is more recent.
2001-08-04 Akim Demaille <akim@epita.fr>
* bin/autom4te.in ($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 `$req' is invalid if it is outdated.
Don't declare it valid before saving it if something went wrong.
2001-08-04 Akim Demaille <akim@epita.fr>
Autom4te shall not encode Autoconf data, and preselecting traces
must be proposed to the users.
* bin/autom4te.in (@required_trace): Remove.
(@preselect): New.
(&parse_args, &print_usage): -p, --preselect is a new option.
(&up_to_date_p): Adjust.
* bin/autoconf.in: Preselect some Autoconf macros.
2001-08-04 Akim Demaille <akim@epita.fr>
* tests/tools.at (autoconf --trace: user macros): Check traces on
macros invoked without arguments, and macros invoked with multiple
lines arguments.
2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
* bin/autom4te.in (handle_traces): Fix rewriting of traces without
arguments.
2001-08-03 Akim Demaille <akim@epita.fr>
* bin/autoconf.in ($@): Work around the usual sh bug.
From Nicolas Joly.

m4_if, and m4_wrap.
2001-08-03 Akim Demaille <akim@epita.fr>
* lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
(m4_divert_pop): Dump the whole diversion stack when a diversion
mismatch happens.
* bin/autom4te.in (&handle_output): Remember of the first
occurrence of a possibly undefined macro, not the last.
Complain about the possibly undefined macros in the same order as
the appear in the output.
* lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
* tests/tools.at (autoconf: forbidden tokens, basic)
(autoconf: forbidden tokens, exceptions): No longer sort
autoconf's stderr, as it is now deterministic.
Check that `dnl' is caught.
2001-08-01 Akim Demaille <akim@epita.fr>
* configure.ac: Bump to 2.52c.
2001-08-01 Akim Demaille <akim@epita.fr>

`END', as `Autom4te::General::END' will be triggered.
