* libm4.m4 (m4_append, m4_list_append): Use m4_define, not define.
On my machine the former implementation takes 4mn 40s to run the
test suite. Using m4_define leads to 4mn 15s.
* acgeneral.m4 (_AC_SUBST): Use AC_EXPAND_ONCE (which uses
m4_define, not define). 4mn.
(_AC_DIVERT): Don't use m4_case. Starting from those 4mn, if you
just move NORMAL* first in m4_case, the test suite is run in 3mn.
If instead of using m4, you use an `associative array' plus a
wrapper (current implementation), it falls to 2mn.
* acgeneral.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
_AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Prefer
for i in : $is; do test $i = : && continue
over

(_AC_COPYRIGHT_SEPARATOR): Remove.
(AC_COPYRIGHT): Adjust.
(_AC_INIT_HELP, _AC_INIT_VERSION): Name the package you configure
when you want.
(_AC_INIT): Adjust.
* configure.in (AC_PACKAGE): Add.

* autoconf.sh (translate_awk::BEGIN): No longer change RS.
(translate_awk::body): Move to the END.
Instead, accumulate the input in `request'.

AC_OUTPUT over quotes too: stop that.
Reported by Martin Buchholz.
* doc/autoconf.texi (Output): Don't expand on the ternary
AC_OUTPUT.
* acgeneral.m4 (AC_OUTPUT): Don't over quote $2 and $3.
* acgeneral.m4 (_AC_INIT_PREPARE_ENVIRONMENT): New macro.
Handle the NLS envvars, and IFS.
(_AC_INIT_PREPARE): Use it, no longer set the NLS envvars.
(_AC_WHICH_A, AC_PATH_PROG): Rely on the default IFS.
* acspecific.m4 (AC_PROG_INSTALL, AC_FUNC_SELECT_ARGTYPES):
Likewise.
AC_TRY_LINK, AC_TRY_RUN_NATIVE): Simplify the removal of the
contest files: don't remove them before running the actions, just
remove them at the end of the macro.
(m4_case,m4_match): Rewrite to use m4_shiftn (for readability reasons).
(m4_for): Add the STEP argument and some argument-verifying asserts.
(m4_split): Correct spaces to tabulator in regexp.
* acspecific.m4 (AC_FUNC_SELECT_ARGTYPES): Use a single cache
variable instead of three.
Use AC_CACHE_CHECK.
Shorten the name of the var loops, they are no longer cached.
Include sys/types.h unconditionally.
`select' returns an int, fixes Autoconf/46.
Don't display parens in the user messages.
(AC_REVISION): Require AC_INIT, not _AC_INIT_BINSH.
(AC_INIT): Do what _AC_INIT_BINSH used to.
Don't require _AC_INIT_VERSION, just call it.
Rename as _AC_INIT.
(AC_INIT): New macro, single expansion wrapper around _AC_INIT.
(_AC_COPYRIGHT_SEPARATOR): New.
(AC_COPYRIGHT): Use it.
Require AC_INIT, not _AC_INIT_VERSION.
* doc/autoconf.texi (Versions): Promote as first section of
`Setup'.
Rename as `Notices'.
Document AC_COPYRIGHT.
Don't give false reasons for placing AC_REVISION before AC_INIT,
the place no longer matters.
CONFIG_FILES, we had to expand _AC_OUTPUT_FILES into the KILL
diversion, because it is AC_OUTPUT_FILES which undiverted the
AC_SUBST sed script at its proper place, otherwise it would have
been undiverted at the end of `configure', leading to an sh syntax
error.
Now that we no longer use a diversion, we don't need to call
AC_OUTPUT_FILES if useless.
(AC_OUTPUT_FILES): Rename as _AC_OUTPUT_FILES.
(AC_OUTPUT_LINKS): Rename as _AC_OUTPUT_LINKS.
Automake calls it, and usually users do too. If it happens,
`--program-prefix=g' actually prepend two (or more) `g'.
* acgeneral.m4 (AC_DEFUN_ONCE): New macro.
(AC_ARG_PROGRAM): AC_DEFUNed_ONCE. Or is it AC_DEFUN_ONCE'd? :).
No longer AC_EXPAND_ONCE the help string, the macro itself is
expanded at most once.
Rename the here-doc tag EOF_SED as EOF.
* acgeneral.m4 (_AC_INIT_PARSE_ARGS): Stop global double quoting,
failed experiment.
Merge all the var=val AC_SUBST(var) into AC_SUBST(var, val).
(AC_SUBST): Implement support for 2nd arg.
* doc/autoconf.texi (Setting Output Variables): Adjust.
Suggested by Alexandre Oliva and Lars J. Aas
* libm4.m4 (ifndef): New macro.
* acgeneral.m4 (AC_DIVERT): New macro, maps a diversion name to
its value. The diversions now have a short name, e.g., `NOTICE',
instead of the former macros which had long names, e.g.,
`AC_DIVERSION_NOTICE'.
(AC_DIVERT_PUSH): Adjust.
(AC_DIVERT_POP): Use ifndef.
(AC_DIVERSION_CURRENT): Rename as `AC_DIVERT_DIVERSION' to stay
within the `AC_DIVERT' name domain.
Adjust all callers.
* acspecific.m4: Adjust all callers.
file names.
(translate_awk::BEGIN): Set RS to "0" so that the whole file be a
single record.
(translate_awk::trans): Convert from array to function.
(translate_awk::error): New function.
(translate_awk::main action): Implement support for ${sep}@ and
${sep}*. Use trans() and error().
(translate_awk): Don't put space before user functions call, it is
not portable.
Remove trailing `;', this is not C :).
(task trace): Quote `$traces' when you eval it, to protect the
white spaces.
Propagate `translate_awk' failures to `autoconf.sh'.
Translate the quadrigraphs.
* autoheader.sh: s/-eq/=/.
Uniform ordering of variable initializations, option handling.
Don't use quotes where useless (foo=$1, not foo="$1").
Propagate `run_m4' and `run_m4f'.
Use `$0' in --help.
* autoconf.sh: Likewise.
* autoreconf.sh: Likewise.
* autoupdate.sh: Likewise.
* ifnames.sh: Likewise.
* autoupdate.m4: Small bug: at the end `dnl' is disabled, so use
`m4_dnl'.
* autoconf.sh (initialization): New var, new option.
(option loop): When you need an arg, make sure there is one.
(run_m4f): New var, which content is that of the former...
(run_m4): Don't use m4 frozen state files.
Change all callers.
Don't pass AC_LOCALDIR, not documented, and unused.
(task trace): Honor `--verbose' and `--initialization'.
(globally): Send `--verbose' messages in stderr.
Fix random typos.
* autoconf.sh (debug): New var, new option.
Adjust the trap code.
(task trace): Instead of decoding `m4 --trace' with sed, decode it
with m4 itself.
($silent_m4): New file, which disables m4's `errprint'.
($trace_m4): New file. Logistic for the m4 which is in charge of
decoding the traces of the first.
($translate_awk): Transform a user trace request into $trace_m4
code.
2.5.1 only the last one is honored:
> echo "foonbar" | egrep -e 'foo' -e 'bar'
bar
> echo "foonbar" | egrep -e 'bar' -e 'foo'

(AC_ENV_SAVE): Join the egrep patterns into a single big one.
* tests/Makefile.am (EGREP_EXCLUDE): Rename as FILTER_MACROS.
Join the egrep patterns into a single big one.

* libm4.m4 (m4_quote): s/$@/$*/.
* acgeneral.m4 (AC_COPYRIGHT): Prepend `# ' to the lines that goes
on the top of `configure'. Actually, prepend `@%:@ ' so that
there are as many evaluations on both sides.
(_AC_INIT_VERSION): No longer strip `# '.

* acgeneral.m4 (AC_DIVERSION_DEFAULTS, AC_DIVERSION_INIT_PREPARE):
New diversion numbers.
(AC_DIVERSION_INIT): Renamed as...
(AC_DIVERSION_INIT_PARSE_ARGS): this.

there are more pops than pushes, die with dignity.
(AC_COPYRIGHT): New macro.

here...
(_AC_INIT_PREPARE): to here.

Reported by Erez Zadok.
* tests/atspecific.m4 (AT_TEST_MACRO): Set AC_CONFIG_AUX_DIR to
top_srcdir in configure.in, and pass the value of top_srcdir to
configure.
Any character before the colon is accepted because network drives
can be assigned characters outside the [a-zA-Z] range. DOS-style
relative paths (?:foo/bar) are also considered absolute for
Autoconf's purposes since the path '../?:foo/bar' is invalid.
* acgeneral.m4 (AC_OUTPUT_FILES): Treat DOS-style paths (?:*') as
absolute.
(AC_OUTPUT_SUBDIRS): Likewise.
(AC_PATH_PROG): Make pattern for matching DOS-style paths the same
as that used in AC_OUTPUT_FILES and AC_OUTPUT_SUBDIRS.
(AC_CHECK_PROG): Use it. Use ifval.
(AC_CHECK_PROGS): Use ifval. Fix the quoting.
* tests/semantics.m4: Test AC_CHECK_PROG.

also AU macros.
Some CVS tricks were used so that history is kept in both the top
directory, and in doc/.
* doc/Makefile.am: New file.
* Makefile.am: Adjusted.
* configure.in: Adjusted.
* autoconf.texi: Moved from here to...
* doc/autoconf.texi: here.
* make-stdts.texi: Likewise.
* install.texi: Likewise.
* texinfo.tex: Likewise.
Reported by Erez Zadok.
* tests/torture.m4 (config.status under extreme conditions):
Reorganized. Because files required by this test were created
outside the pair AT_SETUP/AT_CLEANUP, when the test fails and
autotest extracts this test, the `debug' script does not contain
the files it needs. Now AT_SETUP/AT_CLEANUP encloses the full
auto contained section.
Reported by Franc,ois Pinard and Rainer Orth.
* autoreconf.sh: Removed spurious `;;'.
Formatting changes.
* tests/tools.m4 (Syntax of the scripts): Run `sh -n' on all the
shell scripts.
Also remove trailing blanks.

From Jim Meyering.
* autoheader.sh (usage): The usage is to use $0 here.
(ah_base): Be in TMPDIR.
Install the `trap' before creating the first tmp file.
Also trap on 0.
`configure', not `config.status', hence use `conftest' for tmp

Removed forgotten developer comment.
Double quoting the whole body is nicer than just the part that
needs to be.
From Dan Ackroyd.
* acgeneral.m4 (AC_INIT_PARSE_ARGS, AC_INIT_PREPARE,
AC_CACHE_SAVE, AC_PREFIX_PROGRAM, AC_OUTPUT,
_AC_OUTPUT_CONFIG_STATUS, AC_OUTPUT_MAKE_DEFS, AC_OUTPUT_FILES,
_AC_OUTPUT_HEADERS, AC_OUTPUT_LINKS, AC_OUTPUT_SUBDIRS): Quit
playing with changequotes, @BKL@ and Co.! Just quote properly.
Test it.
* acgeneral.m4 (AC_OUTPUT_HEADERS): Renamed as...
(_AC_OUTPUT_HEADERS): this. All callers changed.
Don't mess with changequote, just quote properly.
Bug 1. Because of the `#' in `ac_dA', the quotes <<>> were not
removed, and therefore the sed script contained `<<define>>'
instead of `define'. Now that the block is properly quoted, there
is no need to quote `define'.
Bug 2. Once a `#define' substitution performed, we were branching
to the top of the sed script (`t top'). This resulted in an
endless substitution of `#define foo 1' to `#define foo 1'.
Branching is not enough: you also have to fetch the next input
line, i.e., use `t' instead of `t t' in ac_dD, and don't output
`: top' in `config.defines'.
Though it was correct for `#undef' templates, just apply the same
transformation to `ac_uD' and `config.undefs'.
Bug 3. Don't try to preserve what was behind the value in the
template, since on
#define NAME "bar baz"
it leads to
#define NAME 1 baz"
Now `ac_dB' catches everything behind the NAME (making sure there
is at least a space) and `ac_dC' only outputs a space.
* tests/torture.m4: Check that various forms of `#define' header
templates are properly handled.
* acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): It is smarter to use a
quoted here doc to output the section providing defaults for
CONFIG_*.
Don't rm the CONFIG_FILES here but in..
(AC_OUTPUT_FILES) [test -n "$CONFIG_FILES"]: here.
Hm, actually, no, just don't remove them at all, let the newly
created files replace the old ones, exactly as in
AC_OUTPUT_HEADERS.
From Graham Jenkins.

* doc/autoconf.texi (Generic Types): Reorganized. Explain
everything about AC_CHECK_TYPE and Co.
AC_LINK_FILES($from, $to)
`$from' and `$to' can be lists, hence `AC_CONFIG_LINKS($to:$from)'

Invite the user to try --help for invalid options.
(AC_INIT_PARSE_ARGS): Likewise.
(_AC_OUTPUT_COMMANDS): This. All callers changed.
Disable the verbose message until Automake uses the new features
of `config.status'.
Reported by Jim Meyering.
* acgeneral.m4 (AC_INIT_PARSE_ARGS, getopt loop): Always define
ac_optarg as the rhs of the first `=', not only on `-.*=', so that
`configure var=val' defines ac_optarg=val.
Improve the robustness to shell special characters:
- Use grep when checking that shell variable names are valid.
- Quote the quotes in ac_optarg before `eval var='$ac_optarg''.
- Quote the quotes when building ac_configure_args.
* tests/torture.m4: Test that `./configure foo=bar' works properly.
* acgeneral.m4 (AU_DEFINE): New macros, pulled out from AU_DEFUN.
Defines a macro in `autoupdate::' with all the required wrapping
for `autoupdate'.
(AU_DEFUN): Use it.

avoid unneeded warnings for obsolete use of AC_OUTPUT_COMMANDS.
(autoupdate::AC_OUTPUT): New macro.

AC_CONFIG_COMMANDS.
(AC_OUTPUT_COMMANDS_CNT): New variable, declared both in

AC_CONFIG_FILES): Use it, and also temporarily divert to -1
instead of spamming dnl everywhere.
(AC_OUTPUT_CONFIG_STATUS): Make sure to output the INIT-CMDS
before the other sections, it'd be a pity to initialize after the
use :).

* acgeneral.m4 (AC_CHECK_SIZEOF): Don't over quote $1, some []
were left in the C code, and had the macro fail.
Use AC_INCLUDES_DEFAULT.
* doc/autoconf.texi: Mention default includes. Explain stdio.h
must always be given.
* tests/atspecific.m4 (TEST_MACRO): Updated the list of
exceptions.
(AT_CHECK_DEFINES): New macro, to check the content of config.h.
* tests/semantics.m4: All the tests are updated to use
AT_CHECK_DEFINES.
Test AC_CHECK_SIZEOF, AC_CHECK_HEADERS, and AC_CHECK_FUNCS.
Autoconf testing.
* tests/suite.m4 (AT_TEST_MACRO): Moved to
* tests/atspecific.m4 (AT_TEST_MACRO): here.
* tests/syntax.m4 (TEST_MACRO): Moved to
* tests/atspecific.m4 (TEST_MACRO): here. Don't test /^AC_INIT/,
nor /^AC_PROG_(CC|CXX|F77)_(GNU|WORKS)$/: they are already
tried elsewhere.
* tests/Makefile.am: Adjusted.
condition out the test case if __cpluscplus.
Don't document the autoheader template twice, one is enough.
* autoheader.m4 (AC_CONFIG_HEADER): don't hook on this guy, but
on...
(AC_CONFIG_HEADERS), since the former is defined on the latter.
for it. Just quote properly!
condition out the test case if __cpluscplus.
AC_REQUIRE AC_PROG_CC_STDC.
Fix slightly the display of the result (formerly the first run
says `none needed', and later, because of the cache `no').
(AC_C_INLINE, AC_C_VOLATILE): AC_REQUIRE AC_PROG_CC_STDC.
* doc/autoconf.texi (AC_C_CONST): Give a few hints on the
motivation for trusting the C++ compilers.
(AT_CASE): new macro.
(AT_CHECK): Use it. Don't changequote for patsubst, there is no
need.
* tests/syntax.m4 (TEST_MACRO): Don't run AC_ARG_VAR.
Reported by Jim Meyering.
Use AT_CASE.
* acgeneral.m4 (AC_CANONICAL_THING): define, not AC_DEFUN.
Don't AC_PROVIDE, there is no need.
When calling `config.sub`, also || exit 1, to catch failures from
config.sub.
* acspecific.m4 (AC_SYS_LONG_FILE_NAMES): Use ac_val, not val.
(AC_EXEEXT): Use ac_file, not file.
* tests/actest.m4: New file, holding extra Autoconf macros used
during the testing.
(AC_ENV_SAVE): New macro, save the sh variables in a file.
* tests/suite.m4 (AT_TEST_MACRO, Generation of configure.in):
include actest.m4, and call twice AC_ENV_SAVE to compare the
variables before and after the macro.
* tests/Makefile.am (macro.m4): Don't test macros that are
required: they will be tested somewhere else.
* acgeneral.m4 (AC_CHECK_MEMBER): It is not smart to define
ac_Foo, and use AC_Foo. Got rid of AC_Member_Aggregate and
AC_Member_Member which were complicating more than simplifying.
(AC_CHECK_DECLS): Use m4 lists.
(AC_CHECK_TYPES): A comma was missing.
* autoheader.m4: (AC_CHECK_DECLS): Use m4 lists.
* doc/autoconf.texi (Generic Declarations): AC_CHECK_DELCS uses m4
lists.
* tests/semantics.m4: New file. Collection of semantical tests:
verify that the tests are positive and negative when appropriate.
Test AC_CHECK_MEMBERS, AC_CHECK_DECLS and AC_CHECK_TYPES.
* autoheader.m4 (AH_DEFUN): New macro. Combination of define and
AH_HOOK.
(AC_TRY_RUN, AC_DEFINE, AC_DEFINE_UNQUOTED, AC_CHECK_LIB,
AC_CHECK_HEADERS, AC_CHECK_HEADERS_DIRENT, AC_CHECK_DECLS,
AC_CHECK_FUNCS, AC_CHECK_SIZEOF, AC_PROG_LEX, AC_CHECK_MEMBERS,
AC_CHECK_TYPE, AC_FUNC_ALLOCA, AC_CHECK_TYPES, AC_C_CHAR_UNSIGNED,
AC_AIX, AC_F77_WRAPPERS, AC_CONFIG_HEADER): All the former calls
to define and AH_HOOK in autoheader.m4 are replaced by AH_DEFUN.
Fix the bugs discovered.
* acgeneral.m4 (AC_CANONICAL_THING): Quote the
AC_REQUIRE([AC_CANONICAL_HOST]). Bug triggered by the use of
AC_CANONICAL_BUILD alone in configure.in. Also, quote the
arguments of macros (eg, ifelse([$1]...), not ifelse($1...)).
(m4_case): New macro.
(AC_LINKER_OPTION): Don't clash with user's name space
(s/i/ac_link_opt).
(AC_LIST_MEMBER_OF). You mean AC_FATAL, not AC_MSG_ERROR.
Quote properly the argument.
dnl out the empty lines that result from m4 pure code.
Don't pollute the user name space.
Use AC_SHELL_IFELSE.
(AC_F77_NAME_MANGLING): Don't use `test -o'. There are still
name space problems.
* tests/Makefile.am (macros.m4): Also fetch the macros from
acgeneral.m4.
Fix the discovered bugs.
* tests/atgeneral.m4 (AT_CHECK): Don't just exit 1 when you want
to propagate the failure of a test: exit with the same exit
status, at least to preserve 77 (=ignore).
* tests/syntax.m4 (TEST_MACRO): Run also autoheader. Don't run
this test on all the macros, some just cannot run without
arguments.
* acgeneral.m4 (AC_OUTPUT_CONFIG_STATUS): In the if egrep/fi for
#define templates, add a `:' to prevent syntax errors in
config.status when there are no AC_DEFINE performed.
* autoheader.m4 (AH_TEMPLATE): Don't use _AC_SH_QUOTE here, use it
in...
(AH_VERBATIM): here. Now AH_C_UNSIGNED_CHAR is no longer failing
(formerly it would produce a non backslashed backquote, which
made sh choke).
extern software (so that the test suite doesn't fail on them).
* acgeneral.m4 (AC_MSG_ERROR, AC_MSG_ERROR_UNQUOTED): Allow an
optional $2: exit status.
* doc/autoconf.texi: Document.
* acspecific.m4 (AC_PROG_CC_WORKS, PROG_CXX_WORKS,
AC_PROG_F77_WORKS): Exit 77 if the compiler does not work.
Introduce a new style of testing, independent from DejaGNU.
Introduce the logistics.
* configure.in: Initialize AT, and output tests/atconfig, and
tests/Makefile.
* m4/atconfig.m4: New file.
* m4/Makefile.am: Adjusted.
* aclocal.m4: Include atconfig.m4.
* Makefile.am: Adjusted.
* tests/Makefile.am: New file.
* tests/atgeneral.m4: Likewise.
* tests/atconfig.in: Likewise.
Write tests.
* tests/syntax.m4: New file, in charge of checking the validity of
the sh code produced by the macros defined in acspecific.m4.
acgeneral.m4 is not checked here, because these macros require
arguments.
* tests/suite.m4: New file. Run syntax.m4.
A test suite will be introduced which tries to run all the
specific macros, but hasbeen'd macro make configure die with bad
exit status. So we wish to distinguish live macros from defunct
macros at the moment they are AC_DEFUN'd, not in their body. Hm,
defunct, defunct... Hey! That's a good name!
* acgeneral.m4 (AC_DEFUNCT): New macro, comparable to AC_DEFUN,
but for macros which are no longer defined. Replaces AC_HASBEEN.
(AC_HASBEEN): Defunct. Well, removed in fact.
(AC_HAVE_LIBRARY): Don't use AC_DEFUN and AC_HASBEEN, just
AC_DEFUNCT.
* acspecific.m4 (AC_UNISTD_H, AC_USG, AC_MEMORY_H, AC_DIR_HEADER,
AC_INT_16_BITS, AC_LONG_64_BITS): Likewise.
(AC_XENIX_DIR): It was defunct even before I declared it was: was
depending upon AC_DIR_HEADER which is defunct. So AC_DEFUNCT'ed
now.
(AC_DYNIX_SEQ, AC_IRIX_SUN, AC_SCO_INTL): While we're here, you
too are defunct now.
* autoconf.texi (Obsolete Macros): Replace the documentation of
AC_HASBEEN with that of AC_DEFUNCT.
Make autoconf support --install.
* autoconf.sh (task install): New task. Extract the set of
auxiliary m4 files a configure.in depends upon. Install links
from library files to the local dir so that the packages depends
only on local extensions. Check that the user includes exactly
the files she needs.
Require GNU m4 1.4 (well 1.3 in fact).
Because we are ready to handle the case where there are no frozen
files, we *have* to pass a -I, which is dangerous in conjunction
with the silent including of `aclocal.m4': you may include things
that were not expected. Since anyway handling pre 1.3 complicates
the task, just require an m4 which supports reloading of frozen
files.
* acspecific.m4 (AC_PROG_GNU_M4): Check for --reload.
* autoconf.sh: Likewise
* autoheader.sh: Likewise.
* configure.in: Explicitly state the m4 version you want.
No need for foo="`bar`", foo=`bar` is fine.
Simplify ${foo} and ${1} into $foo and $1.
* acgeneral.m4 (ac_LF_and_DOT): Remove the double quotes.
* acspecific.m4 (AC_PROG_CC_C_O, AC_PROG_F77_C_O): Likewise.
* autoconf.sh: Likewise.
* autoheader.sh: Likewise.
* autoreconf.sh: Likewise.
* autoupdate.sh: Likewise.
* ifnames.sh: Remove all the code and messages related to
AC_MACRODIR, since ifnames is not related to macros in anyway.
New version of AC_INCLUDE, which does not glob, nor rely upon the
shell. Add AC_INCLUDES too. Help tracking multiple inclusions.
* acgeneral.m4 (m4_errprint, m4_warn, m4_fatal): New macros,
variations around errprint.
(m4_include_unique): New macro which registers what are the files
already included, and warns if some are included several times.
(m4_include, m4_sinclude): New macro, using m4_include_unique.
(AC_INCLUDE): Is now just a wrapper of m4_include.
(AC_INIT): Use m4_sinclude, not sinclude.
(_AC_ERRPRINT): Removed, m4_errprint is here!
(AC_WARNING, AC_FATAL): Wrappers of m4_warn and m4_fatal.
Be kind to Automake: list the arguments of selected macros
(for instance AC_SUBST will list each variable which may be
substitued).
* autoconf.sh (--trace, --output): New options.
Implement tracing of macros.
trap also on 0, so that there is no need to rm here and there.
* autoconf.texi (Output): Document --trace and --output.
Clean up the macros for testing members of aggregates.
* acgeneral.m4 (AC_CHECK_MEMBER): FATAL if $1 has no dot in it.
Use AC_INCLUDE_DEFAULTS.
(AC_C_STRUCT_MEMBER): Removed.
* acspecific.m4 (AC_STRUCT_TIMEZONE): Adapted to AC_CHECK_MEMBERS.
(AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Adapted to
AC_CHECK_MEMBERS and obsoleted.
(AC_STRUCT_ST_BLOCKS): Adapted to AC_CHECK_MEMBERS.
* autoconf.texi (AC_STRUCT_ST_BLKSIZE, HAVE_STRUCT_STAT_ST_RDEV):
Explain they are obsoleted, and how to migrate.
(AC_STRUCT_ST_BLOCKS, AC_STRUCT_TIMEZONE): Explain that the
AC_DEFINE changed (but the former #defines remain defined
currently).
(AC_C_STRUCT_MEMBER): Removed, replaced by the definitions of
AC_CHECK_MEMBER and AC_CHECK_MEMBERS.
Install a uniform set of default includes.
* acgeneral.m4 (AC_INCLUDES_DEFAULT): New macro. Expands in its
argument if non empty, otherwise a default list of includes.
(AC_CHECK_DECL, AC_CHECK_TYPE_INTERNAL): Use AC_INCLUDES_DEFAULT.
* autoconf.texi: Adjusted.
Fix a bit of the brokenness of AC_CHECK_TYPE.
* acgeneral.m4 (AC_CHECK_TYPE_INTERNAL): New macro, inspired from
the former AC_CHECK_TYPE. This macro is exactly the one that
ought to be named AC_CHECK_TYPE: it just checks, and executes user
actions. In the future, this macro ought to be renamed
AC_CHECK_TYPE.
There is a big difference with the former AC_CHECK_TYPE: instead
of grepping in the headers, it tries to compile a variable
declaration. This is both safer, slower, and better, since now we
can check for compiler types (e.g., unsigned long long).
(AC_CHECK_TYPES): The looping and AC_DEFINEing version of the
previous macro. Uses m4 loops.
(AC_CHECK_TYPE): Reimplemented on top of AC_CHECK_TYPE_INTERNAL.
* autoheader.m4 (AH_CHECK_TYPE, AH_CHECK_TYPES): New macros,
hooked.
* autoconf.texi (@ovar): New macro, for optional variables.
(Generic Typedefs): Document AC_CHECK_TYPES.
* autoheader.texi: (AH_CHECK_TYPE, AH_CHECK_TYPES): New macros.
(Epilogue): Hooks them.
Create man pages for the executables.
* Makefile.am (SUBDIRS): Add `man' and prepend `.' so that
executables be built before help2man is run.
* configure.in (AC_OUTPUT): Add man/Makefile.
AC_MSG_ERROR, not AC_ERROR.
Check for missing help2man.
* man/Makefile.am: New file.
* man/autoconf.x: Likewise.
* man/autoreconf.x: Likewise.
* man/autoheader.x: Likewise.
* man/autoscan.x: Likewise.
* man/autoupdate.x: Likewise.
* man/ifnames.x: Likewise.
* man/common.x: Likewise.
* acgeneral.m4 (AC_CONFIG_LINKS): Allow a second argument,
commands to run, as AC_CONFIG_FILES and HEADERS.
(AC_LIST_LINKS_COMMANDS): New growing string. Initialize.
(AC_OUTPUT_LINKS): Use it.
(AC_OUTPUT_FILES, AC_OUTPUT_HEADERS, AC_OUTPUT_LINKS): Don't
pretend to have arguments: you don't depend upon it.
(AC_OUTPUT): Call the previous macros without arguments.
Clean up dead comments/code. Clean up the incompatibilities
between quoted and non quoted _AC_ECHO and the like.
* acgeneral.m4: Remove the comments on the no longer defined AC_TR.
(_AC_SH_QUOTE): Be robust to active symbols.
(_AC_ECHO): Quote properly the argument.
(AC_TRY_RUN): Don't quote [AC_TRY_RUN] in the warning.
* acgeneral.m4 (AC_INIT_NOTICE, AC_INIT_PREPARE, AC_ARG_ENABLE,
AC_ARG_WITH, AC, TRY_COMPILER, AC_TRY_RUN, AC_TRY_CPP,
AC_EGREP_CPP): Use @PND@ instead of [#]: it looses the editors
that try to match the pairs of (), [] etc.
Fix the compatibility of the compiling macros with C++.
* acgeneral.m4 (AC_TRY_COMPILE, AC_TRY_LINK, AC_CHECK_SIZEOF): Use
`int main () {...}', instead of `main () {...}'.
* acspecific.m4 (AC_TYPE_GETGROUPS, AC_FUNC_CLOSEDIR_VOID,
AC_FUNC_FNMATCH, AC_FUNC_GETPGRP, AC_FUNC_SETPGRP, AC_FUNC_VFORK,
AC_FUNC_WAIT3, AC_FUNC_ALLOCA, AC_FUNC_UTIME_NULL,
AC_FUNC_SETVBUF_REVERSED, AC_FUNC_MEMCMP, AC_C_CHAR_UNSIGNED,
AC_C_LONG_DOUBLE, AC_C_BIGENDIAN, AC_SYS_RESTARTABLE_SYSCALLS):
Likewise.
* acspecific.m4 (AC_FUNC_FNMATCH): Call
AC_CHECK_HEADERS(fnmatch.h), and include fnmatch.h in the compiled
code.
* acgeneral.m4 (AC_COMPILE_CHECK, AC_TRY_COMPILE,
AC_TRY_RUN_NATIVE, AC_OUTPUT_CONFIG_STATUS): Use @PND@ instead of
[#]: it looses the editors that try to match the pairs of (), []
etc.
Formatting changes.
* acspecific.m4: Formatting changes.
Allow standard beta version numbers.
* configure.in: Declare version 2.14a.
* acgeneral.m4 (AC_UNGNITS): New macro which transform version
numbers to pure digits (2.14a to 2.14.0.1, 2.15z to 2.15.0.26
etc.).
(AC_PREREQ): Normalize argument and AC_ACVERSION via AC_UNGNITS.
Fix the --version of all the executables.
* Makefile.am (editsh, editpl): Substitute also PACKAGE and
VERSION.
* autoconf.sh (version): New string.
(--version): Use it.
(--help) Output on stdout, not stderr.
* autoheader.sh: Likewise.
* autoreconf.sh: Likewise.
* autoscan.pl: Likewise.
* autoupdate.sh: Likewise.
* ifnames.sh: Likewise.
Perform a better checking for missing templates in autoheader.
* autoheader.m4 (AH_HOOK): When hook AC_FOO on AH_FOO, define the
new AC_FOO to be the expansion of both AH_FOO *and* AC_FOO. See
its definition for the motivations.
* autoheader.m4 (AH_FUNC_ALLOCA): Remove the now useless
additional templates.
Provide a means to specify commands to run before config.status is
created (and, for symmetry, after it is created).
This is typically needed by Automake so that AC_REPLACEd functions
go through deansification via
LIBOBJS=`echo $LIBOBJS | sed 's/\.o /\$U.o /g;s/\.o$/\$U.o/'`
and/or by Libtool which needs to define LTLIBOBJS and others:
LTLIBOBJS=`echo $LIBOBJS | sed 's/\.o/\.lo/g'`
AC_SUBST(LTLIBOBJS)
* acgeneral.m4 (AC_OUTPUT_PRE_COMMANDS): New growing string.
Initialize.
(AC_OUTPUT_POST_COMMANDS): Likewise.
(AC_CONFIG_PRE_COMMANDS): New macro, grows AC_OUTPUT_PRE_COMMANDS.
(AC_CONFIG_PRE_COMMANDS): Likewise.
(AC_OUTPUT): Run AC_OUTPUT_PRE_COMMANDS before
AC_OUTPUT_CONFIG_STATUS, and AC_OUTPUT_POST_COMMANDS after.
Remove spurious empty lines appearing in configures.
* acgeneral.m4 (AC_CONFIG_UNIQUE): Produce no output. Instead of
fighting with dnl, divert to KILL upon entry, and pop at exit.
Create AC_CONFIG_HEADERS which has the same interface as the other
AC_CONFIG_*S.
* acgeneral.m4 (AC_CONFIG_HEADERS): New macro, with the same
interface as AC_CONFIG_LINKS and AC_CONFIG_FILES.
(AC_LIST_HEADERS_COMMANDS): New growing string, initialize it.
(AC_CONFIG_HEADER): Rename as...
(AC_CONFIG_HEADERS): this, for consistency.
(AC_CONFIG_HEADER): New macro, which calls AC_OUTPUT_HEADERS.
(AC_OUTPUT_HEADERS): The square brackets for sed and grep were
not properly quoted: use @BKL@ and @BKR@.
(AC_OUTPUT_HEADERS): Run the AC_LIST_HEADERS_COMMANDS.
* acgeneral.m4 (AC_OUTPUT): Once config.status created, before
running it, trap to `exit 1' so that config.status is not removed
if configure is interrupted when config.status is complete.
* acgeneral.m4 (AC_OUTPUT_CONFIG_STATUS): When recognizing
arguments, accept only foo, and no longer foo:foo.in etc.
config.status: Speed up the creation of config headers (about four
times faster on Linux).
* acgeneral.m4 (AC_OUTPUT_HEADERS): Remove the ac_e
family.
Changed ac_uD and ac_dD to `...;t t', instead of `...g'.
Instead of creating `conftest.vals' with both ac_e, ac_d,
and ac_u family, preprocess to strip the trailing spaces, and
create `conftest.defines' with the ac_d family, and then
`conftest.undefs' for the ac_e family.
Break up both `conftest.defines' and `conftest.undefs'. Insert a
top label and a global test for `#defines' and `#undef' before.
Call `conftest.defines' if there are #define in the input.
Call `conftest.undefs'.
Rename the family AC_NEED_DECL as AC_CHECK: it is more uniform,
but keep defining NEED_FOO_DECL when `foo' is not declared. Files
not using Autoconf behave better when declarations lacks than when
they are wrong. So the unset position should off, hence #if NEEDS
instead of #if !HAVE (which is triggered when HAVE is not set).
* acgeneral.m4 (AC_NEED_DECL): Renamed as...
(AC_CHECK_DECL): This. Make sure the arguments are the usual
IF-FOUND, IF-NOT-FOUND.
(AC_NEED_DECLS, AC_CHECK_DECLS): Likewise.
* autoconf.texi (Generic Declarations): Document the changes
aforementioned.
* autoheader.m4 (AH_NEED_DECLS): Renamed as
(AH_CHECK_DECLS): This.
(AH_HOOKS): Hook AH_CHECK_DECLS on AC_CHECK_DECLS instead of
_NEED_.
Revamp the handling of the arguments of config.status: instead of
looping over config_files etc. to recognize the file names, use
the case which handles the options.
Suggested by Alexandre Oliva.
* acgeneral.m4 (ifset): Renamed as...
(ifval): This. All callers changed.
(ifset): New macro, which tests if a macro is set to a non empty
value.
* acgeneral.m4: Initialize growing lists and strings to empty, to
ease the tests.
(AC_CONFIG_HEADER): Quote AC_LIST_HEADERS in the define, to handle
the case AC_LIST_HEADERS is initialized.
* acgeneral.m4: (AC_OUTPUT_CONFIG_STATUS): New macro, pulled out
from...
(AC_OUTPUT): Instead of using $1, $2 and $3, pass them to the
official macros (AC_CONFIG_FILES, AC_OUTPUT_COMMANTS).
Call AC_OUTPUT_CONFIG_STATUS.
(option handling): Use the case-esac to recognize arguments.
(AC_OUTPUT_COMMANDS): Fix the missing fi;done.
Add a means to specify commands to be run by config.status. At
the difference of AC_OUTPUT_COMMANDS, require that the set of
commands be named, so that both
CONFIG_COMMANDS=foo ./config.status
and
./config.status foo
perform the Right Thing.
* acgeneral.m4 (AC_CONFIG_UNIQUE): Also check in
AC_LIST_COMMANDS.
(AC_CONFIG_FILES): Remove a dead pushdef.
(AC_CONFIG_COMMANDS): New macro.
(AC_LIST_COMMANDS): New config list.
(AC_LIST_COMMANDS_COMMANDS): New growing string.
(AC_OUTPUT_COMMANDS_COMMANDS): New macro, output config commands
in config.status.
(AC_OUTPUT): Take AC_LIST_COMMANDS into account.
(AC_OUTPUT): Call AC_OUTPUT_COMMANDS_COMMANDS.
New macro: AC_CONFIG_FILES which is very much like AC_OUTPUT but
that one associates commands to run when a config file is
created. For instance for a shell script `foo', one uses
AC_CONFIG_FILES(foo, chmod +x foo).
In addition, check that the same name is never used twice in
config files, headers, subdirs and links.
* acgeneral.m4 (m4_append): Don't insert new line between
elements.
(m4_list_append): New macro.
(AC_CONFIG_IF_MEMBER): New macro which tests if a file is member
of a config list.
(AC_CONFIG_UNIQUE): New macro which ensures that a config file
name is not yet used.
(AC_CONFIG_HEADER, AC_CONFIG_LINKS, AC_CONFIG_SUBDIRS): Use
AC_CONFIG_UNIQUE.
* acgeneral.m4 (AC_CONFIG_FILES): New macro.
(AC_LIST_FILES): New list, which stores arguments of
AC_CONFIG_LISTS the same as AC_LIST_LINKS stores AC_CONFIG_LINKS
etc.
(AC_OUTPUT): No longer rely on $1 to designate the config files:
register them via AC_CONFIG_FILES. All uses of $1 replaced by
uses of AC_LIST_FILES.
(AC_OUTPUT_FILES): Run the commands associated to the
CONFIG_FILES.
Provide the m4 infrastructure for defining AH_ hooks.
* autoheader.m4 (AH_HOOK): New macro.
Hook all the AC_ macros to their AH_siblings in AH_HOOKS.
Run AH_HOOKS.
* acgeneral.m4 (m4_append): New macro.
(m4_list_append, m4_list_add): Removed.
* autoheader.m4 (AC_FUNC_ALLOCA): Rename from this ...
(AH_FUNC_ALLOCA): ... to this. Includes all the needed templates.
(AC_C_CHAR_UNSIGNED): Rename from this ...
(AH_C_CHAR_UNSIGNED): ... to this.
* Makefile.am (CLEANFILES): New explicit variable.
(editsh): acdatadir is no longer defined, so use pkgdatadir.
(editpl): Likewise. From Akim Demaille <akim@epita.fr>.
* Makefile.in: Regenerate.
* configure: Regenerate.
* aclocal.m4: New generated file.
* Makefile.in: Regenerate with Automake.
* testsuite/Makefile.in: Likewise.
1999-10-31 Akim Demaille <akim@epita.fr>
Use Automake. Based on files from Ben Elliston.
* acgeneral.m4: No longer define AC_ACVERSION, include
acversion.m4.
* acversion.m4.in: New AC_CONFIG_FILE.
* acspecific.m4: Few formating changes.
* autoconf.texi: No longer define EDITION, VERSION and UPDATED:
include version.texi.
AC_OUTPUT the Makefiles mentioned below and acversion.m4.
* configure.in: Use AM_INIT_AUTOMAKE.
Do not AC_ARG_PROGRAM: AM_INIT_AUTOMAKE does it.
* Makefile.am: New file.
* mdate-sh: Likewise.
* missing: Likewise.
* testsuite/Makefile.am: Likewise.
* testsuite/autoconf.s/defines.exp: Changed `fail' and `pass' in
`xfail' and `xpass'. The testsuite checks that acconfig.h
templates the AC_DEFINEs. Since we no longer rely on acconfig.h,
the test is obsolete.
* acspecific.m4 (AC_PROG_BINSH, AC_PROG_SED): Don't quote the name
of the macro defined; the testsuite does not recognize this
syntax. From Akim Demaille <akim@epita.fr>.
