174 Work around DJGPP shell function return bug with command substitutions.
175 DJGPP bash 2.04 has a bug in that `return $ac_retval' done in a
176 shell function which also contains a command substitution causes
177 the shell to barf. For more details and a fix see:
178 <http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp-workers/2009/09/09/03:35:08>

207 DJGPP fix: remove both conftest and conftest.exe.
208 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
209 and both `conftest' and `conftest.exe' with `-o conftest', but not
210 with `-o conftest.exe'.
211 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Also remove
212 `conftest' without $ac_exeext suffix.

215 * lib/autoconf/general.m4 (AC_SITE_LOAD, AC_CACHE_LOAD): Do not
216 load the cache or site file if it is `/dev/null', as DJGPP treats

5074 Cover more potentially problemtic file names. Use the new
5077 Properly handle funny file names for headers in config.status.
5078 The test suite did not cover this bug because the code was not
5079 quoting properly the arguments of `rm -f' (which "fails" silently)
5080 as well as the arguments of `diff' (whose output was redirected to
5081 /dev/null so we couldn't see its error message).

5196 Add 'testsuite -C dir'.
5197 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
5199 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
5201 <DEFAULTS>: Delay computation of variables based on $at_dir...
5202 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
5203 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
5204 <PARSE_ARGS>: Parse new option.
5205 <HELP_TUNING>: Document it.

5221 * doc/autoconf.texi (Particular Programs): Do not mention the
5222 Autoconf version in which the AC_PROG_INSTALL change was done.
5223 Suggested by Paul Eggert.
5225 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5227 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
5228 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
5229 mode, we change to the source directory, also set $ac_pwd so we
5230 do not go back to the build tree for the next config subdir.
5231 * tests/torture.at (Deep Package): Extend test to contain two
5232 config subdirs on the top level.
5234 Fix parallel `maintainer-check'.
5235 * Makefile.am (maintainer-check-tests): Depend on `all'.

5286 (m4_require): Use m4_do, not m4_join.
5288 Fix some whitespace tests on cygwin.
5289 * tests/tools.at (autom4te and whitespace in file names): Restore
5290 font-lock. Create $TMPDIR before it might be used.

5293 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
5295 Optimize AC_REQUIRE.

5308 * tests/base.at (Input/Output): Likewise.
5309 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
5310 config.guess, and config.sub to test source tree.
5311 Drop AC_CONFIG_AUX_DIR setting.
5312 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
5313 * tests/torture.at (Substitute a 2000-byte string): Drop
5314 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
5315 (Substitute a newline, datarootdir workaround): Likewise.
5316 (Define a newline): Adjust for linenumber changes in configure.ac.
5317 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
5319 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
5320 if `pwd` contains whitespace.

5326 * tests/m4sh.at (LINENO): Quote $0.
5328 Fix testsuite program wrapper for whitespace in `pwd`.
5329 The problem here is that the usual mantra is that command
5330 variables can contain arguments, thus we cannot just escape
5331 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
5332 $top_builddir/tests directory early in $PATH, so that the
5333 wrappers are found by their plain name.
5334 * tests/wrapper.as: Put $testdir early in $PATH.

5347 <at_func_create_debugging_script, Driver Loop>:
5348 Quote $at_group_dir.
5349 * tests/autotest.at (whitespace in absolute testdir): New test.
5351 * lib/autom4te.in: Quote @datadir@.
5353 Proper file name escaping in Autoconf programs and Perl modules.
5354 This includes escaping of characters special to the shell
5355 as well as special to Perl, e.g., leading `<' or `>'.
5356 For example, when $file starts with `>', `open ">$file"'
5357 wrongly tries to append to a different file.
5358 * bin/autoconf.as: Fix quoting for autom4te options.
5359 * lib/Autom4te/General.pm (shell_quote): New function, taken
5360 from coreutils, written by Jim Meyering.

5369 * tests/tools.at (autom4te and whitespace in file names): Extend
5370 test. Test twice, with special characters allowed on w32, and the
5371 rest. Test leading and trailing whitespace, for `open_quote'.
5372 (autotools and whitespace in file names): New, analogous test.
5373 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
5374 by Russ Allbery and Eric Blake.

5378 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.

5380 (update_file, contents): Use it.
5382 * Makefile.am (autom4te-update): Rewrite for git.
5384 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5386 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
5388 Fix copyright years.
5389 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
5390 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.

5400 * doc/Makefile.am (TEXINFO_TEX): Add.
5402 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
5404 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
5405 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
5406 #undef as this runs afoul of our new way of creating config.h.
5407 Problem reported by Jim Meyering in
5408 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

5413 * bin/autom4te.in (files_to_options): Quote active characters

5424 `#AT_STOP_...' line at the end of each test.
5426 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5428 * lib/autotest/general.m4 (AT_INIT): For awk line number
5429 extraction script, ensure `$at_group' has a defined value
5430 even for the empty set, and properly quote its usage inside
5433 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5435 * doc/autoconf.texi (Shell Functions): New chapter. Document
5436 IRIX sh $0 issue in functions, move content from ...
5437 (Portable Shell): ... here.

5442 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5444 * lib/autotest/general.m4 (AT_INIT): Exit awk script after

5455 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
5456 Do not use $0 inside a function, as IRIX sh will set that to the
5457 function name rather than the script invocation name.
5459 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
5460 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5462 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
5463 to extract test scripts.
5464 (AT_INIT): Extract and cache test script line numbers.
5466 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5468 * lib/autotest/general.m4: Revert 2007-11-15 patch and
5469 subsequent fixups; the awk -> here-document conversion trashes
5470 performance too much with AIX sh.
5472 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5474 * tests/local.at: Do not test m4, perl with AT_TESTED.
5476 Diagnose and guard against write errors dealing with config.status.
5477 The general idea is this: all write failures from `configure'
5478 writing `config.status' are indicated by $ac_write_error, which
5479 is only checked at the end. This is safe because config.status
5480 code is not executed before the file is complete. Other write
5481 failures, be they inside config.status, or in sub shell/awk
5482 scripts spawned from configure or config.status, typically need
5483 earlier checking, as their results are used right afterwards.
5484 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
5485 before writing config.status, check afterwards.
5486 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
5487 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
5488 Set `ac_write_error' for write failures to config.status. Barf
5489 upon write failures to temporary files.
5490 Adjust note about closing and reopening the here-document.
5491 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
5492 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
5493 reopening the here-document.
5494 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5495 Ensure `ac_write_error' does not escape into config.status.
5496 Also, add a couple of code paths not yet exercised in the test
5497 suite: a config file with input from stdin, and a config header
5499 Suggestion for catching write errors by Bruno Haible.
5501 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5503 Avoid error with Tru64 awk and testsuite lines with many words.
5504 * lib/autotest/general.m4 (AT_INIT): In the awk script that
5505 reads the testsuite, set the field separator to an unusual value,
5506 in order to not run over the limit of 199 fields. Tru64 4.0D awk
5507 even splits the input if $i, i>0, was never accessed in the script.
5509 Revert 2007-10-17 change.
5510 * TODO: Multiline args in config files and headers mean something
5511 different and are not fixed, see
5512 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
5513 Report by Stepan Kasal.
5515 * doc/autoconf.texi (Generic Programs): Fix typo.
5517 2007-11-16 Stepan Kasal <kasal@ucw.cz>
5519 AC_*_TOOL does not canonicalize the prefix
5520 * doc/autoconf.texi (Generic Programs): Do not say that
5521 the *_TOOL macros canonicalize, they simply use the `host_alias'.
5523 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5525 Diagnose write errors in config.status instantiations.
5526 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
5527 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
5529 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5530 Extend test to also check for some write error failures, using...
5531 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
5532 Report by Bruno Haible.
5535 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
5537 (_AT_CHECK): Use less indentation, to save space.
5539 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5541 Add witness macro for @top_build_prefix@ substitution.
5542 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
5543 (_AC_OUTPUT_FILE): Mention it here.
5545 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
5546 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5548 * lib/autotest/general.m4 (at_func_test): Remove.
5549 (AT_INIT): Pre-extract test groups into separate files.
5550 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
5551 Remove at-test-source files together with the $at_group_dir.
5552 * tests/autotest.at (Long test source lines): New test.
5554 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5556 Shell functions and variables may share a namespace.
5557 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
5560 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
5562 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
5565 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5567 * lib/autoconf/status.m4: Fix a couple of comment typos.
5569 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
5571 2007-11-13 Jim Meyering <meyering@redhat.com>
5573 Clean up the rule to create "expr".
5574 * tests/Makefile.am (expr): Don't redirect directly to target.
5575 Redirect just once, not for each echo statement.
5576 Use $@, not literal "expr".
5578 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
5580 Don't worry about preprocessor when testing long long.
5581 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
5582 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
5583 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
5584 These no longer check for preprocessor flaws.
5585 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
5586 Do not check for preprocessor flaws.
5588 2007-11-13 Jim Meyering <meyering@redhat.com>
5590 Adapt dependencies, now that a version change doesn't modify configure.ac
5591 * GNUmakefile: Remove "make clean" kludge.
5592 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
5594 Don't redirect directly to target.
5595 Use $@, not literal "version.m4".
5597 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5599 * doc/autoconf.texi (Making testsuite Scripts): Document
5600 ":;{" shorthand as in previous patch.
5602 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
5604 * doc/autoconf.texi (Limitations of Builtins): Document problem
5605 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
5607 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
5608 Use ":;{" shorthand.
5609 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
5611 2007-11-12 Jim Meyering <meyering@redhat.com>
5613 Add more non-srcdir build support.
5614 * GNUmakefile (dummy): Split a long line.
5615 Add -v option to autoreconf invocation.
5617 Remove the autoreconf-provided INSTALL, so that we regenerate it.
5618 * GNUmakefile (dummy): Remove INSTALL.
5620 Remove racy commands to build scripts in bin/ and tests/.
5621 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
5622 are guaranteed to be built, remove the rules that tried to build
5623 them. Before, with a parallel build, these rules could lead to
5624 two processes writing tests/wrapper.in concurrently.
5626 Build in man/ only *after* building in bin/ and tests/.
5627 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
5628 in both bin/ and tests/.
5630 Accommodate non-srcdir build-from-checkout.
5631 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
5632 Use git's --git-dir=$srcdir/.git option.
5633 Add quotes, in case tarball_version_file contains shell meta-characters.
5634 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
5635 * configure.ac: Pass "." to git-version-gen.
5637 Avoid spurious test failures due to version skew.
5638 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
5640 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5642 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
5643 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
5644 Remove conftest.dSYM directory.
5645 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
5646 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
5647 Remove `conftest.*' recursively.
5648 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
5649 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
5651 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
5653 Report and analysis by Jeff Squyres and Peter O'Gorman.
5655 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
5657 Fix typos in variable names.
5658 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
5660 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
5662 Document that $((expression)) is not portable.
5663 * doc/autoconf.texi (Shell Substitutions): Here.
5665 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5667 Ignore configure --help* errors due to LINENO-impaired shells.
5668 * tests/torture.at (Configuring subdirectories, Deep Package):
5669 In the --help* tests in read-only trees, make `.' temporarily
5670 writable again for the `stderr' file, and ignore errors due to
5671 the attempt to write configure.lineno.
5672 Report by Patrick Welche.
5674 2007-11-10 Jim Meyering <meyering@redhat.com>
5676 Generate package.m4 in build-dir, not srcdir.
5677 * tests/Makefile.am (package.m4): Adjust target.
5678 Don't redirect directly to $@.
5679 (CLEANFILES): Add package.m4.
5680 ($(TESTSUITE)): Depend on just-built package.m4, not the one
5682 When running $(AUTOTEST), search "." before searching $(srcdir).
5684 Avoid a race condition that would make parallel "distclean" fail.
5685 * tests/Makefile.am (distclean-generic): Replace the default,
5686 automake-provided rule with an identical one, but with an additional
5687 dependency on distclean-local. Simply adding the dependency would
5688 cause automake not to emit the rule at all.
5689 * BUGS: Building with -jN works, now.
5691 Distribute git-version-gen.
5692 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
5693 since GNUmakefile is distributed, and requires it for dist* rules.
5695 Remove two more generated files from version control.
5696 * INSTALL: Remove generated file.
5697 * lib/autoscan/autoscan.list: Remove generated file.
5699 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
5701 * GNUmakefile (PATH): Remove stray apostrophes; they become
5702 part of PATH, which isn't wanted here.
5704 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5706 New config files output variable `top_build_prefix'.
5707 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
5709 * doc/autoconf.texi (Preset Output Variables): Document it.
5711 Report by Bob Friesenhahn.
5713 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
5714 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
5715 function, to parametrize arithmetic with expr vs. the shell.
5716 Use it where possible.
5717 Suggestion by Benoit Sigoure.
5719 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
5721 Adjust the documentation of autotest WRT atlocal.
5722 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
5723 when using Automake, to write a rule to produce atlocal, since it's
5724 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
5725 distributed, not atconfig.in.
5727 2007-11-04 Eric Blake <ebb9@byu.net>
5729 Update list information.
5730 * README: Mention new autoconf-commit list.
5731 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
5733 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5735 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
5737 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
5739 * build-aux/.gitignore: Ignore mkinstalldirs.
5741 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
5743 2007-11-03 Jim Meyering <meyering@redhat.com>
5745 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
5746 * build-aux/git-version-gen: This syncs from coreutils.
5748 Adjust the build procedure so "make check" works reliably.
5749 * README-hacking: Include an extra step between "make" and
5750 "make check" to ensure that the latter passes.
5752 Use just-built tools, when possible.
5753 * GNUmakefile (PATH): Set and export here, ...
5754 (dummy): ... rather than here.
5756 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5757 and Andreas Schwab <schwab@suse.de>

5762 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5764 * configure.ac (AC_PREREQ): Require version 2.60, for
5765 AC_PROG_SED, AC_PROG_GREP.

5777 2007-11-03 Eric Blake <ebb9@byu.net>
5779 Support m4 1.4.5 in testsuite.

5782 Reported by Ralf Wildenhues.
5784 2007-11-03 Jim Meyering <meyering@redhat.com>
5786 Remove automake-provided files from version control.

5788 * build-aux/install-sh: Remove file.
5789 * build-aux/missing: Remove file.
5790 * build-aux/mdate-sh: Remove file.
5791 * build-aux/.gitignore: New file.
5792 Suggestion from Ralf Wildenhues.
5794 2007-11-03 Eric Blake <ebb9@byu.net>
5796 Adjust version comparison to account for git snapshot numbers.
5797 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
5798 component separator.
5799 * doc/autoconf.texi (Number processing Macros)
5800 <m4_version_compare>: Document this change.
5801 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
5803 2007-10-30 Bruno Haible <bruno@clisp.org>
5805 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
5806 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
5807 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
5808 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
5809 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
5810 Suggested by Paul Eggert.
5812 2007-10-28 Jim Meyering <meyering@redhat.com>
5814 * README-hacking: Autoconf, Automake, and Perl are required to build.
5815 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
5817 2007-10-28 Jim Meyering <meyering@redhat.com>
5819 README-hacking: Recommend running autoreconf -vi.
5820 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
5821 so that we use just-built tools when they're available.
5822 Suggestions from Ralf Wildenhues.
5824 2007-10-28 Jim Meyering <meyering@redhat.com>
5826 Make inter-release --version output more useful.
5828 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
5829 which indicates that it is built using the 19th change set
5830 (in _some_ repository) following the "v2.61a" tag, and that 58dd
5831 is a prefix of the commit SHA1.
5832 * build-aux/git-version-gen: New file.
5833 * configure.ac: Run it to set the version.
5834 (AM_INIT_AUTOMAKE): Don't check NEWS here.
5835 * Makefile.am (dist-hook): Arrange so that .version appears only
5836 in distribution tarballs, never in a checked-out repository.
5837 * .gitignore: Add .version here, too. Just in case.
5838 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
5839 not configure.ac, now that the version number changes automatically.
5841 Ensure that $(VERSION) is up to date for dist-related targets.
5842 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
5843 git-version-gen doesn't match $(VERSION), but only for dist targets.
5845 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6946 (Macro Names, Defining Directories): Don't mention PATH as a name
6947 for a fully qualified file name, as this usage violates the GNU
6948 coding standards and we shouldn't recommend it.
6950 * lib/autotest/general.m4 (AT_INIT): Don't set PATH to the empty
6951 string and then assume shell builtins like "test" will work.

6994 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp

7114 AC_CHECK_TYPE, AC_CHECK_TYPES.
7115 * doc/autoconf.texi (Generic types): C types must be type-names
7116 (the C terminology), not type-ids (the C++ term). C++ types
7117 must not be anonymous.
7118 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
7119 for C++; this drops support for anonymous struct and union types,
7120 which were problematic anyway.

7139 with objects too. Document the restrictions on its use.
7140 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
7141 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
7142 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
7143 works but the latter doesn't, then it's a valid type.
7144 This lets people use function types and so forth.
7145 For C++ there doesn't seem to be a simple solution, so leave it alone.
7146 (AC_CHECK_SIZEOF): Allow argument to be a variable.
7147 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
7148 AC_CHECK_TYPE; that wasn't documented or necessary.

7205 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
7206 (Limitations of Usual Tools): Also list \< and \>, and mention that

7318 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
7319 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
7320 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
7321 substitution will still be done by the special code.
7322 Report by Jim Meyering.

7366 discussion about the allow_superuser_privileges example,
7367 and change it a bit to make things clearer.
7368 (Optimization and Wraparound): Clarify whether the compiler
7369 will generate an infinite loop for the example derived from
7370 Autoconf's mktime test.
7371 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
7372 Also, clarify unsigned multiplication overflow.
7374 2007-01-04 Eric Blake <ebb9@byu.net>

7388 * doc/autoconf.texi (Integer Overflow): Revised based on today's
7389 feedback. The most important changes document what happens when
7390 you convert an out-of-range value to a signed integer type, and
7391 say that (sum < a) != (b < 0) reliably detects overflow when sum =

7395 rewrite, taking notions from the recent discussion on the gcc and
7396 autoconf mailing lists; please see

7406 preprocessor macro arguments in traced name.
7407 * doc/autoconf.texi (Defining symbols): Document longstanding
7408 support for AC_DEFINE-ing macros with arguments, and document
7409 behavior when the same variable has multiple AC_DEFINEs.
7410 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
7411 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_

7414 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
7416 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
7417 space before "$ac_configure_args" to prevent a 'config.status
7418 --recheck' failure if ac_configure_args doesn't contain a leading
7419 space. This works around a problem with the XEmacs configure.ac,
7420 which uses the (undocumented) ac_configure_args variable
7421 inconsistently with Autoconf.
7423 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
7425 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
7426 Include <limits.h>, and use its INT_MAX to rewrite the
7427 j loop so that it does not overflow 'int'. Problem reported by
7429 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
7430 Play it safe by shifting left by 1 rather than multiplying by 2,
7431 as GCC is less likely to optimize this away when the value
7432 is signed (when it assumes overflow leads to undefined behavior).
7433 Also, don't assume time_t uses two's complement.
7435 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7437 * tests/torture.at (Substitute a 2000-byte string): Avoid using
7438 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
7439 dumps core on it. Report by Tim Rice.
7441 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7443 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
7444 --disable-option-checking to --help output even when
7445 AC_PRESERVE_HELP_ORDER is not used.
7446 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
7447 --with argument, rather than argument with [-.] replaced by
7449 * NEWS: Fix typo in previous change; the news was in the
7452 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
7454 * NEWS: Warnings are now generated by default for unknown
7455 --enable-* and --with-* options.
7456 * doc/autoconf.texi (Option Checking): Renamed from
7457 (Configure Option Checking). Tighten up the wording a bit.
7458 (External Software, Package Options): Cross-reference to Option
7459 Checking, and use this to shorten our section.
7460 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
7461 "$x" to test "x$foo" != x.
7462 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
7463 Don't warn if $enable_option_checking is "no".
7464 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
7465 ac_unrecognized_opts to the empty string.
7466 Don't echo the unrecognized opts, as this might mishandle
7467 backslashes or leading -.
7468 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
7469 usage next to the other --disable-FEATURE options in the
7472 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7474 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
7475 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
7476 Print warning for unrecognized --with and --enable options
7477 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
7478 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
7479 Disable option checking when subdirs are configured.
7480 (AC_OUTPUT): If warnings are enabled, print warning about
7481 unrecognized --with and --enable options at the end of
7482 the configure output (as well as at the beginning).
7483 * doc/autoconf.texi (Option Checking): New node.
7484 Document new option warning functionality.
7486 2006-12-16 Eric Blake <ebb9@byu.net>
7488 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
7489 * NEWS: Start news for current version.
7491 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
7493 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
7494 Define HAVE_GETMNTENT to 1, not to the empty string.
7495 Problem originally reported by Jochen Friedrich in
7496 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
7498 This change prompted by a problem report by Andrey Simonenko in
7499 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
7500 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
7501 object-like macros only, in the traditional portable character
7503 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
7504 Warn about attempts to define things that are not identifiers.
7505 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
7506 awful hack that AC_DEFINEd macro names containing parentheses.
7508 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
7510 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
7511 too drastic, even if Texinfo in theory requires it for info mode.
7513 (config.status Invocation): Renamed back from Recreating a
7515 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
7516 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
7518 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7520 * NEWS: Version 2.61a.
7522 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7523 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7525 * NEWS: Document changes with echo and printf, and the lack
7526 of limits on the total size of multi-line values of substituted
7527 variables, and the AC_FUNC_FSEEKO fix.
7529 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
7531 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
7532 Writing configure.ac.
7533 (Autoconf Input Layout): Renamed from configure.ac Layout.
7534 (Recreating a Configuration): Renamed from config.status Invocation.
7535 (Obsolete Recreation): Renamed from Obsolete config.status Use.
7536 (acconfig Header): Renamed from acconfig.h.
7537 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
7538 (Writing Testsuites): Renamed from Writing testsuite.at.
7539 (Autom4te Cache): Renamed from autom4te.cache.
7541 * BUGS: Remove mention of VPATH problem, since it's now documented
7542 not to be a bug in the Autoconf build procedure itself, but rather
7543 a problem with the proprietary `make' programs.
7545 * doc/autoconf.texi (Build Directories): Add a cross reference
7548 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
7549 * doc/standards.texi: Sync from gnulib.
7551 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
7552 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
7553 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
7554 generated automatically.
7556 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
7558 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
7559 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
7560 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
7562 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7564 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
7565 `CEOF$ac_eof' special marker, the awk script cannot contain a
7566 line matching `^CEOF', so this is not needed any more.
7567 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
7568 special marker in the test.
7570 2006-12-06 Stepan Kasal <kasal@ucw.cz>
7572 * tests/tools.at (autom4te preselections): Use `find -newer';
7573 remove one of the sleeps.
7575 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
7576 more readable, using ...
7577 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
7579 * doc/autoconf.texi (autoheader Invocation): Do not double-
7580 quote the parameter of `AH_BOTTOM' in the example.
7582 2006-12-05 Stepan Kasal <kasal@ucw.cz>
7584 * doc/autoconf.texi (Configuration Headers): Remove the
7585 example with multiple input files.
7586 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
7587 multiple input files.
7589 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7591 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
7592 creating the awk substitution script, handle one input line at a
7593 time, so that the maximum length of a substituted (multi-line)
7594 value is not limited by the size of the sed pattern space.
7595 The trade-off is a slightly repetitive sed script.
7596 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
7597 can only have up to 7 characters, due to Solaris 10 /bin/sed.
7598 * tests/torture.at (Substitute a 2000-byte string): Increase the
7599 test with several long lines, they should not be caught by sed
7602 * tests/tools.at (autom4te preselections): New test, to flag
7603 entries missing from autom4te.cfg.
7604 Report by David Byron <dbyron@hheld.com>.
7606 * tests/torture.at (Substitute a 2000-byte string): Actually use
7607 AC_PROG_AWK, so the last change works as intended.
7608 (Substitute and define special characters): Likewise.
7609 (Substitute a newline): Likewise.
7611 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
7612 instead of `awk' consistently.
7613 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
7614 * tests/torture.at (Torturing config.status): Test both the
7615 result of AC_PROG_AWK and plain awk.
7616 (Substitute a 2000-byte string): Likewise.
7617 (Substitute and define special characters): Likewise.
7618 (Substitute a newline): Likewise.
7620 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
7622 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
7623 can be assigned to a function pointer. Problem reported by
7624 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
7625 part of a patch by Ralf Wildenhues in that same bug report.
7627 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
7629 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
7630 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
7632 2006-12-01 Eric Blake <ebb9@byu.net>
7634 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
7635 cross-compiling from cygwin to mingw.
7636 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
7637 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
7638 to lib/autoconf/c.m4.
7640 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7642 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
7643 string for more reliable failure. Wrap the entire test that
7644 causes the broken Solaris printf to dump core, in a subshell,
7645 so the segmentation fault message is reliably suppressed.
7646 Fix shell expansion errors by using /usr/ucb/echo always;
7647 avoid an error on systems without it by another subshell.
7648 Avoid m4 expansion of `$1'. Set the zeroth argument of the
7649 subshell-$as_echo to `as_echo', for better error message.
7651 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7653 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
7654 `BASH_SOURCE' contain a newline, set them to empty, as they may
7657 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
7659 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
7660 years and is too hard to maintain now. The last straw was
7661 reported by Jerker Baeck in
7662 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
7663 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
7664 * doc/autoconf.texi (Particular Functions): Move
7665 AC_FUNC_SETVBUF_REVERSED from here...
7666 (Obsolete Macros): ... to here. Say that it does nothing now.
7667 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7668 Turn into (almost) a no-op.
7670 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
7672 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
7673 These macros are obsolescent and new applications shouldn't need them.

7681 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
7683 * doc/autoconf.texi (Setting Output Variables): Mention that
7684 @VAR1@VAR2 has unspecified behavior. Problem reported by
7686 * NEWS: Mention this.
7688 * Makefile.am: Put only a single '#' into the copyright notice,
7689 so that it's also present in the output file. Standardize wording
7690 in makefile copyright notices to match GNU coding standards.

7704 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7706 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
7707 in the sed script that mangles the awk script: delete up to the
7708 first exclamation mark only.
7709 * tests/torture.at (Substitute and define special characters):
7712 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7714 Rewrite config files generation: avoid quadratic growth in
7715 the number of substituted variables by using awk instead of sed
7716 for the bulk of the substitutions.
7717 * NEWS: Mention this.
7718 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
7719 forbidden in the output (and thus input) file.
7720 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
7721 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
7722 generate just one large awk script for substitutions,
7723 eliminating much of the earlier complexity, while adding some
7724 new complexity. Only expand the substitution templates at
7725 configure time, for smaller configure script size. If
7726 _AC_SUBST_FILES are used, test 'awk' for working getline support
7727 at config.status time. If absent, interpolate through the
7728 shell. The awk script was written with much help
7729 from Paolo Bonzini and Paul Eggert.
7730 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
7731 (_AC_SED_FRAG_NUM): Likewise.
7732 (_AC_SUBST_CMDS): Renamed from...
7733 (_AC_SED_CMDS): ...this.
7734 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
7735 * tests/torture.at (Substitute a 2000-byte string): Also
7736 substitute a line with 1000 words, and a variable with several
7738 (Substitute and define special characters): Test awk special
7739 characters, and put substitution input strings `@foo@' in the
7740 output, to test that no recursion happens; test several other
7741 combinations from Paolo Bonzini.
7743 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
7745 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
7746 that replaced echo with AS_ECHO where this wasn't necessary.
7747 Problem reportd by Ralf Wildenhues.
7748 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
7749 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
7750 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
7752 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7754 * lib/freeze.mk (GREP): Removed, no need to initialize this.
7756 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
7758 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
7759 that traditional Awk lacks 3-arg "split". It has it.
7760 Mention that FS must be a single character, and a few other
7761 99-byte limits of traditional Awk.
7762 Mention that if (i in a) doesn't work with traditional Awk.
7764 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
7766 * tests/autotest.at (BSx641-newline in command):

7768 (Newline-CODE-BS-newline in command):
7769 (Single-quote-BS-newline in command):
7770 (Single-quote-newline-BS-newline in command):
7771 Use printf '%s\n' instead of echo, for portability to hosts
7772 where echo interprets backslashes. This will break on hosts
7773 that lack printf, but for now let's assume all such hosts
7774 are dead (if not, we should get reports of test failures).
7776 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
7778 'echo' has some portability problems, when given a first argument
7779 with a leading '-', or when given any argument containing '\'.
7780 Avoid using 'echo' in these cases.

7809 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
7810 Don't use ECHO_T, since ECHO_N is now reliable.
7811 * lib/autotest/general.m4 (AT_INIT): Likewise.
7812 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
7813 rather than using a here-document to put the script into a file.
7814 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
7816 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
7817 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
7818 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
7819 bug, but we might as well stop using ECHO_N and ECHO_C internally.
7820 * lib/autotest/general.m4 (AT_SETUP): Likewise.

7822 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7823 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
7824 operand, as AS_ECHO requires. Avoid double file name expansion.
7825 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
7826 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
7827 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
7828 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
7829 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
7830 Double-quote strings that would otherwise contain M4 comments.
7831 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
7833 * configure.ac (AC_INIT): Bump to 2.61a.
7836 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
7840 * configure.ac (AC_INIT): Bump to 2.61.
7843 * tests/autotest.at (Macro with backslash in a test title):
7844 Comment out for now, as this tests neither fails nor passes
7845 reliably. Problem reported by Ralf Wildenhues.
7847 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
7849 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
7850 in previous change, which caused test failures.

7932 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
7935 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
7937 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
7938 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.

7970 Single-quote in a test title,
7971 Double-quote in a test title): Don't expect failure anymore.
7972 (Backslash in a test title): Put a non-whitespace character after the
7973 backslash so that Bourne shells might actually see it as an escape

7976 Pound in a test title,
7977 Comma in a test title,
7978 Quoted Macro in a test title,

7982 Macro with double-quote in a test title,
7983 Macro with backslash in a test title): New tests expected to fail.
7984 * tests/torture.at (#define header templates): M4-quote this title in
7985 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
7986 The visible effect was a stray [] in the testsuite output.
7988 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7990 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
7991 `trap ... 0' inside a function, for AIX sh.
7993 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
7995 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
7996 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
7997 5363) simply issues a warning when dividing by zero at compile
7998 time. Problem reported by Elias Pipping.
8000 2006-10-26 Eric Blake <ebb9@byu.net>
8003 * doc/autoconf.texi (Evaluation Macros): Improve the example to

8029 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
8031 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8032 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
8033 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
8034 reported by Nelson H. F. Beebe for Coreutils 6.4.
8036 * tests/tools.at (autoconf --trace: user macros): Remove test
8037 for tracing multiline macros, since m4 1.4.7a uses a different
8038 way to number lines. Problem reported by Ralf Wildenhues.
8040 2006-10-24 Stepan Kasal <kasal@ucw.cz>

8065 * doc/autoconf.texi (Caching Results): Likewise.
8066 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
8067 AC_CACHE_CHECK_INT, since it's no longer public.
8068 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
8069 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

8099 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
8100 looking for special shell characters.
8101 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
8102 macro defined by AS_VAR_PUSHDEF before passing it as a

8114 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
8116 (Imported from Automake.)
8117 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
8118 which incorrectly sets the mode of an existing destination
8119 directory. In some cases the unpatched install-sh could do the
8120 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
8121 system. We hope this is rare in practice, but it's clearly worth
8122 fixing. Problem reported by Alex Unleashed in
8123 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
8124 Also, don't bother to check for -m bugs unless we're using -m;
8125 suggested by Stepan Kasal.

8129 Import this change from Automake:
8131 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
8132 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
8133 is enabled by default with gnu and gnits strictness.
8134 Report from Bruno Haible.
8136 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

8138 gnu and gnits modes.
8140 Import this change from Config:

8145 Import this change from Gnulib:
8147 2006-09-16 Karl Berry <karl@gnu.org>
8148 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
8149 to avoid sectioning errors.

8162 * build-aux/texinfo.tex (\textdegree): New command.
8164 2006-08-12 Karl Berry <karl@gnu.org>

8169 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
8171 2006-10-13 Stepan Kasal <kasal@ucw.cz>
8173 * doc/autoconf.texi (Autoheader Macros): Warn that the text
8174 added to the template can get mangled.
8176 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8178 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
8179 include the default headers, and redefine obstack_chunk_alloc
8180 and obstack_chunk_free. Fixes false failure with glibc.
8182 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
8184 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

8197 the NonStop platform.
8198 * doc/autoconf.texi (Posix Variants): Likewise.
8199 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
8201 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
8202 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
8203 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
8204 Use a better substitute, by inspecting the output of "ls"
8205 rather than just using ":".
8206 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
8207 rather than AS_EXECUTABLE_P, since we needn't worry about
8208 non-regular files here.
8210 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
8211 due to configuration hassles with this. See Tonya Underwood's report
8212 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

8223 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
8224 initialization which is not inherited through the environment
8225 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
8226 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

8231 problems with mkdir -p -m.
8233 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
8235 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
8236 comment about ac_cpp_err; it was incorrect, and anyway
8237 ac_cpp_err is being removed below.
8238 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
8239 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
8240 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
8242 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
8243 with werror_flag and conftest.err and so forth. This is more
8244 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
8245 and anyway the user shouldn't normally want to see this gorp logged.
8246 Problem reported by Ralf Wildenhues.
8247 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
8248 empty, not 'no', since the rest of the code uses 'test -z'.
8250 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
8252 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
8253 Use a single call to AC_DO_TOKENS rather than multiple, for
8255 (_AC_LINK_IFELSE): Test that resulting file is executable.
8256 Problem reported by mwoehlke in
8257 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
8259 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
8260 than creating a file to use with test -x; this is much faster.
8262 2006-10-02 Bruno Haible <bruno@clisp.org>
8264 * lib/autom4te.in (Automake-preselections): Add
8265 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
8267 2006-09-27 Stepan Kasal <kasal@ucw.cz>
8269 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
8270 standard error, `experr' should be used, not `expout'.
8272 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
8274 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
8275 fseeko testing program twice; just use the earlier result.
8276 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8277 Set cache var to 'unknown' (not 'no') if leaving the macro unset
8278 still doesn't let the program compile.
8279 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
8282 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
8283 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
8284 include it, without including anything else.
8285 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
8287 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
8289 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8291 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
8292 `error.h', and include it, for a `error_at_line' prototype.
8293 Use a nonempty format string in the link test.
8294 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
8295 for a declaration of wait3.

8301 can apply to constants too, and that it checks for macro defns.
8302 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

8304 values. Problem reported by Ralf Wildenhues.

8796 * doc/autoconf.texi: Be more consistent about using @acronym with
8797 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
8798 quite right (it talked about "OSF/Tru64", even though the
8799 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
8800 and it even mentioned "OSF 4"!) and at this point there's little
8801 reason to talk about OSF any more, since it died in 1994.
8802 (Specific Compiler Characteristics): Simplify example of
8803 negative-size array.
8804 (File Descriptors): Reorder to make the text flow better.
8805 Remove joke about "appreciate the various levels"; I didn't get it.
8806 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
8807 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
8808 (File Descriptors, Limitations of Usual Tools):
8809 Tone down the advice against renaming or removing open files.
8810 (Limitations of Usual Tools): Add a new section, on 'rm'.
8812 2006-06-26 Stepan Kasal <kasal@ucw.cz>
8814 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
8815 -lXt in LIBS, idea from Karsten Hopp; this was due since
8818 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
8819 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
8820 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
8821 (which belong to Xt, not X itself). See Debian bug 327655.
8823 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8825 * configure.ac (AC_INIT): Bump to 2.60a.
8828 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8832 * configure.ac, NEWS: Update.
8834 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8836 * config/texinfo.tex: Sync from upstream.
8838 * bin/autom4te.in (handle_traces): Transform the `@S|@'
8839 quadrigraph correctly in traces.
8841 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
8844 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
8845 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
8847 * doc/autoconf.texi (Changed Directory Variables): New node,
8848 to document the whole `datarootdir' business a bit better.
8850 * tests/torture.at (datarootdir workaround): Extend test.
8851 Prompted by report by Alexandre Julliard.
8853 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
8855 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
8856 when using default mode of IBM C 6 for AIX. Problem and two-line
8857 fix reported by Larry Jones.
8859 2006-06-22 Alexandre Julliard <julliard@winehq.org>
8861 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
8862 about literal '${datarootdir}' if a definition is found in the
8865 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
8867 * NEWS: Use "M4" rather than "m4" when appropriate.
8868 Problem reported by Eric Blake.
8869 * doc/autoconf.texi: Likewise.
8870 Use @acronym around BSD, GCC, and GNU when appropriate.
8871 (Why GNU M4): Renamed from "Why GNU m4".
8872 (Redefined M4 Macros): Mention that Posix
8873 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
8874 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
8877 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8879 * bin/autom4te.in (handle_output): Do not forbid the empty
8881 * tests/tools.at (autoconf: the empty token): New test.
8883 2006-06-20 Stepan Kasal <kasal@ucw.cz>
8885 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
8886 calls, so that we do not care whether they are LIFO or FIFO;
8887 in the m4_wrap, do not check which diversion is the topmost
8888 one, just check that the stack is balanced at the end.
8889 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
8890 base diversion forever--pop the previous diversion before
8891 opening the new one; consequently, remove the m4_wrap call.
8892 * lib/autotest/general.m4 (AT_INIT): Likewise.
8893 * tests/m4sugar.at: Do not use
8894 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
8896 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
8897 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8899 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
8900 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
8901 Rework example of m4wrap token-pasting trouble so that it doesn't
8902 care whether it's LIFO or FIFO.
8903 Fix some "contrary to"s that are awkward in English.
8905 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8907 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
8908 to `yes' instead of `int$1_t' if the type is found, for more
8909 consistent configure output (where $1 is the number of bits).
8910 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
8911 Suggested by Bruno Haible.
8913 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
8914 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
8915 with system headers. Report by Bruno Haible.
8917 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8919 * config/config.guess, config/config.sub: Sync from upstream.
8921 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
8922 in order to avoid picking up an older installed frozen m4sh.m4f.
8923 Besides an outdated shell startup, this could have been created
8924 by an earlier M4 version with incompatible frozen file format.
8926 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
8928 * README: Recommend m4 1.4.4 instead of 1.4.3..
8929 * doc/autoconf.texi: Likewise.
8930 (Special Chars in Names): Say that $(.FOO) is portable, as
8931 suggested by Stepan Kasal.
8932 (Installation Directory Variables, Build Directories):
8933 (Automatic Remaking, Subdirectories, Fortran Compiler):
8934 (Making testsuite Scripts, Defining Directories):
8935 Quote variable usages better.
8936 (Making testsuite Scripts): Add clean-local rule to makefile
8937 snippet, by Eric Blake.
8938 (Installation Directory Variables): Fix table item font.
8939 Reword slightly to clarify. Generalize advice about
8940 not using special characters to include all file-related
8941 vars, not just VPATH.
8942 (Special Chars in Variables): Warn about special characters in
8944 (Assignments): Clarify default-value example as suggested by
8946 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
8947 (Special Shell Variables): Note leading ./ or ../, as suggested
8949 (Limitations of Builtins): Under cd, warn about CDPATH.
8950 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
8953 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8955 * doc/autoconf.texi (Configuration Actions): Remove duplicate
8956 `@var', for texi2html.
8957 (Systemology): Some more word wrapping, for DVI output.
8958 (autom4te Invocation): The short option for `--melt' is `-M',
8961 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
8963 * doc/autoconf.texi: More formatting and English tweaks,
8964 many suggested by Ralf Wildenhues.
8965 Reword to avoid "@code{...}'s" and the like, since it's ugly
8966 with Emacs info mode. discontents -> woes.
8967 Put a few "will"s back. time stamp -> timestamp.
8968 side-effect -> side effect.
8970 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
8972 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
8973 Warn about $@ not persisting. Problem reported by Julien Danjou in
8974 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
8975 (Special Chars in Names): Renamed from Leading _ in Macro Names.
8976 Mention other special chars, too.
8978 2006-06-14 Eric Blake <ebb9@byu.net>
8980 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
8982 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
8984 * doc/autoconf.texi: Some systematic minor improvements, as
8985 follows. Use "makefile" when talking about makefiles
8986 generally (which might be named "makefile" or "Makefile" or even
8987 "foo.mk"), "Makefile" when talking about a specific makefile
8988 called "Makefile". This unclutters the text from weird quotes
8989 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
8990 values" rather than "@var{foo}s" and similar constructs containing
8991 "}s". Use "Make rules" rather than "Makefile rules". Minor
8992 English-language improvements. Change the prefix "sub-" to "sub"
8994 Put blank lines around examples more consistently.
8995 Avoid "rather" and "very" as intensifiers.
8996 Avoid "will" as an auxiliary.
8997 (Limitations of Make): Split this node into....
8998 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
8999 (Leading _ in Macro Names, Backslash-Newline-Newline):
9000 (Backslash-Newline Comments, Long Lines in Makefiles):
9001 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
9002 (obj/ and Make, make -k Status, VPATH and Make):
9003 (VPATH and Double-colon, $< in Explicit Rules):
9004 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
9005 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
9006 New nodes, resulting from splitup of Limitations of Make.
9007 All cross-references changed. Raise the top node from
9008 a section to a chapter, and all subnodes accordingly.
9009 Redo the introductory wording to match the new organization.
9010 (Installation Directory Variables): Use an example that is
9011 closer to what Autoconf actually does. Mention that VPATH's
9012 value should not contain metacharacters or white space.
9013 (Fortran Compiler): Fix a VPATH bug in an example.
9014 (Leading _ in Macro Names): Mention that this problem is no longer
9015 of practical concern.
9016 (VPATH and Make): Reword the advice to make it clearer
9017 that Autoconf and Automake support VPATH in non-GNU make, but
9018 many packages have bugs in this area.
9019 ($< in Explicit Rules): Refer to Build Directories rather
9020 than using a (non-VPATH-safe) example.
9021 (Automatic Rule Rewriting): Mention the sort of disaster that
9022 can ensue with Solaris-style rule rewriting with VPATH.
9024 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9026 * doc/install.texi (Compilers and Options): Weaken the
9027 suggestion to use GNU make for VPATH builds.
9029 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
9030 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
9032 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
9033 in regular expression.
9035 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9037 * doc/autoconf.texi (Installation Directory Variables):
9038 Drop extra @samp from `@table @samp' item.
9039 (Limitations of Usual Tools): Comment fix.
9040 Do not nest @samp just to point to other table items.
9041 (Writing testsuite.at) <AT_CHECK>: The second argument to
9042 `@dvar' is already @samp'ed.
9043 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
9044 do not use @var in the second argument.
9046 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
9048 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
9049 $as_shell.exe too. Problem reported by Andreas Buening in
9050 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
9052 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9054 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
9055 `unused variable' compiler warning, for `-Wall -Werror'.
9056 Reported by Jaap Haitsma in
9057 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
9059 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
9061 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
9062 case the compiler dumps core. Problem reported for
9063 OpenServer 5.0.7 by Tim Rice in
9064 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
9065 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9068 2006-06-06 Tim Rice <tim@multitalents.net>.
9070 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
9071 "ERROR" only shows up in "make check" output if there is an
9074 2006-06-06 Eric Blake <ebb9@byu.net>
9076 * tests/tools.at (automatically allowed tokens): Fix typo.
9078 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9080 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
9082 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
9083 typically overflows on x86 CPUs, even though the C standard
9086 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9088 * configure.ac (AC_INIT): Bump to 2.59e.
9091 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9095 * config/texinfo.tex: Sync from upstream.
9097 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
9098 seen, invoke libtoolize with `--ltdl' argument.
9099 * lib/autom4te.in (Autoreconf-preselections): Adjust.
9101 Suggested by Eric Blake.
9103 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9105 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
9106 reported by Ralf Wildenhues.
9107 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
9109 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9113 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9115 * doc/autoconf.texi: Modernize some of the references to Solaris.
9117 2006-06-05 Stepan Kasal <kasal@ucw.cz>
9119 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
9120 message issued by AC_REQUIRE.
9121 * tests/m4sugar.at: Check m4_require's error message.
9122 * tests/base.at: Check AC_REQUIRE's error message.
9123 * tests/local.at (AT_CHECK_M4): New macro, almost identical
9125 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
9127 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
9128 `expout' as the last parameter.
9129 * tests/tools.at: Adapt to the above change.
9131 2006-06-04 Stepan Kasal <kasal@ucw.cz>
9133 * doc/autoconf.texi (Limitations of Usual Tools): Correct
9134 information about race-free implementations of mkdir.
9136 2006-06-04 Eric Blake <ebb9@byu.net>
9138 * bin/autoreconf.in (help): Document M4 environment variable.
9139 * bin/autoconf.as (Usage): Likewise.
9140 * bin/autom4te.in (help): Likewise.
9141 * doc/autoconf.texi (autom4te Invocation): Likewise.
9143 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
9145 * NEWS: GNU make now recommended for VPATH builds.
9146 Mention that some macros are now documented to be obsolescent.
9147 * doc/autoconf.texi:
9148 Prefer "current" to "modern" to describe
9149 currently-used (albeit perhaps old-fashioned) hosts.
9150 Mention which ancient features no longer need to be worried about.
9151 setgid -> set-group-ID
9152 setuid -> set-user-ID (these are the Posix terms)
9153 Fix some misuses of "only".
9154 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
9155 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
9156 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
9157 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
9158 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
9159 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):

9161 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
9162 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
9163 Mention that these macros are obsolescent.
9164 (Installation Directory Variables): shall -> should
9165 (File Descriptors): Mention that 0, 1, 2 might get reopened.
9166 Mention that it's now safe to use 3 and 4.
9167 (Limitations of Usual Tools): cp -r is now specified by Posix.
9168 Omit longwinded and obsolescent discussion of cp -f.
9169 Modernize discussion of expr, ls.
9170 (Limitations of Make): Modernize discussion of VPATH builds.
9171 Mention $? as a workaround in some cases.
9172 * doc/install.texi (Basic Installation):
9173 Mention "./configure; make; make install" first. Be more
9174 specific about why this file is generic. Remove unnecessary
9175 parens. Remove misleading "only". Remove obsolete advice
9176 about csh. Don't say "configure" takes awhile; say it
9177 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
9178 and CC=c99 rather than CC=c89, as these are blessed by current
9179 Posix. Recommend GNU make if doing a VPATH build.
9181 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
9183 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
9184 examples involving shell prompts.
9186 2006-06-02 Stepan Kasal <kasal@ucw.cz>
9187 and Paul Eggert <eggert@cs.ucla.edu>
9189 * doc/autoconf.texi (Here-Documents): Add details about the
9190 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
9191 use "here-documents" instead of "here documents".
9193 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9195 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
9197 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
9199 * doc/autoconf.texi (File System Conventions): Warn about ":"
9200 anywhere in directory names.
9202 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
9204 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
9205 about quoting the case statement, just in case.
9206 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
9207 was fixed in ksh93g; reported by Ralf Wildenhues.
9209 2006-05-31 Stepan Kasal <kasal@ucw.cz>
9211 * doc/autoconf.texi (System Services): Do not document
9212 overriding EXEEXT via ac_cv_exeext=ext.

9221 argument with leading hyphen. Problem reported by Paul Eggert.
9223 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9225 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
9226 about quoting ac_try: quote all of it, if any of it seems suspicious.
9227 This means we don't have to worry about ${ or sed any more.
9228 Also, double-quote the case statement, to work around misuses via
9229 underquoting as reported by Ralf Wildenhues in
9230 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
9231 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
9232 undocumented and dangerous macro.
9233 Problem reported by Ralf Wildenhues in
9234 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
9236 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9238 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
9239 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
9240 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
9242 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9244 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
9245 since evidently some packages rely on the old, broken behavior.
9246 Problem reported by Ralf Wildenhues in
9247 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
9248 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
9249 pre-2006-05-26 definitions, but leave in the comments that
9250 these macros are dangerous and should not be used.
9251 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
9252 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
9253 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
9254 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
9255 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
9257 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
9259 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
9260 the use of 'tr', since this is our only use of 'tr'.
9262 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9263 and Paul Eggert <eggert@cs.ucla.edu>
9265 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
9266 Don't assume 'grep' works on long lines, since AIX grep doesn't.
9268 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9270 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
9271 the output file in the `${datarootdir}' test.
9273 2005-05-28 Stepan Kasal <kasal@ucw.cz>
9274 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9276 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
9277 mention of `datarootdir' in the input file(s), but literal
9278 `${datarootdir}' in the output file, and we haven't warned yet,
9279 then warn as well: the user may have (erroneously) used
9280 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
9281 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
9282 * tests/torture.at (datarootdir workaround): Extend this test.
9285 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9286 and Paul Eggert <eggert@cs.ucla.edu>
9288 * doc/autoconf.texi (autoheader Invocation): The first argument to
9289 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
9290 alternatives and clear up the language a bit.
9292 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
9294 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
9295 ac_config_guess, ac_config_sub, ac_configure.
9296 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9297 Fix typo that prevented an unnecessary space from being removed.
9298 Problems reported by Ralf Wildenhues in:
9299 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
9301 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
9303 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
9304 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
9305 Don't use the term "thread-safe" to talk about mkdir race
9306 conditions, since the problem is more a process than a thread
9307 issue. Problem reported by Stepan Kasal in:
9308 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
9309 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
9310 the test for 'install' more closely. Look at MKDIR_P first.
9311 Look in the PATH, and at /opt/sfw/bin.
9312 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
9313 Don't bother to try mkdir -p, since we already check mkdir --version;
9314 just look at the version number. (There's no easy way to check
9315 for race-free implementations.)
9316 * tests/tools.at (autoconf: subdirectories): Adjust to above
9317 changes, since MKDIR_P now might end in "/mkdir -p".
9319 * doc/autoconf.texi (autoheader Invocation): Mention that the
9320 first arg of AC_DEFINE_UNQUOTED must be a literal.
9321 Problem reported by Ben Pfaff in
9322 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
9324 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
9325 * doc/autoconf.texi (Special Chars in Variables): New section.
9326 (Preset Output Variables): Warn about special chars in CPPFLAGS.
9327 (Installation Directory Variables): Quote $(datadir) better.
9328 (Limitations of Builtins): Describe some of eval's trickiness.
9330 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
9331 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
9332 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
9333 in front of every arg, not just trailing args. Quote apostrophes.
9334 (_AC_EVAL_ECHO): New macro.
9335 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
9336 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
9338 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
9339 exposed by quoting of eval argument. Put the command on line line
9341 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
9342 (_AC_PATH_X, AC_PATH_X): Quote more safely.
9343 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
9344 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
9345 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
9346 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
9347 Use eval more safely.
9348 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
9349 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
9351 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
9352 lines, exposed by quoting of eval argument.
9354 2006-05-26 Stepan Kasal <kasal@ucw.cz>
9355 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9357 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
9358 initialization of `ac_cv_exeext', do not override it if it was
9359 already set, unless it was set to `no', for compatibility with
9360 Autoconf-2.13, and comment this.
9361 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
9362 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
9363 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
9364 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
9365 Document that this test may be overridden by setting
9368 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9370 Revert these two patches:
9372 2006-04-06 Eric Blake <ebb9@byu.net>
9373 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
9374 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
9377 2006-04-01 Stepan Kasal <kasal@ucw.cz>
9378 Clean up _AC_COMPILER_EXEEXT* macros.
9379 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
9380 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
9381 ac_file to the name of the default output file and call
9382 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
9383 initial `rm' of the candidate files...
9384 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
9385 the same list in subsequent `rm' calls, and for the temporary
9386 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
9387 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
9388 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
9389 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
9390 no longer needed) by libtool. Make it a cache check.
9391 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
9392 copied here by mistake.
9393 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
9394 _AC_COMPILER_EXEEXT.
9395 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
9396 _AC_COMPILER_OBJEXT directly.
9397 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
9399 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9401 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
9402 Fix description of how the buggy `sed' works.
9404 2006-05-25 Noah Misch <noah@cs.caltech.edu>
9408 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
9409 ENOLCK. Only mention `make -j' when applicable. Only raise
9410 fatal errors when `make -j' is involved. Improve error message.
9412 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9414 * doc/autoconf.texi (Here-Documents): We now know more about
9415 the variable expansion in here documents bug.
9416 Thanks to Tim Rice and Stepan Kasal.
9418 * doc/autoconf.texi (Making testsuite Scripts): Add an example
9419 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
9421 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9423 * tests/autotest.at (Multiline command from M4 expansion):
9424 No failure to be expected if the shell quotes newlines in
9425 commands in the `set -x' output. Report by Tim Rice.
9428 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9430 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
9431 expansion in the here-documents used by config.status, as that
9432 runs afoul of the Korn shell version M-12/28/93d bug described in
9433 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
9434 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
9435 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
9437 2006-05-23 Jim Meyering <jim@meyering.net>
9439 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
9440 Fix typo introduced with 2006-04-02 change. It reversed the sense
9443 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9445 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
9446 ac_dB slightly, to save bytes in the script.
9447 Max out at 50 lines, rather than 96; this is more likely
9448 (though not guaranteed) to avoid obscure 'sed' failures.
9450 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9452 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
9453 `tr -d -' as bad option argument. Work around this by deleting
9454 an unrelated character.
9455 Report by Tim Rice <tim@multitalents.net>.
9457 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
9458 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
9459 Stepan Kasal <kasal@ucw.cz>
9461 * doc/autoconf.texi (Particular Programs): Do not promise that
9462 we always prefer the GNU version of the program, and that we
9463 search according to PATH; both rules can have exceptions.
9464 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
9465 AC_PROG_SED. Move descriptions of limitations
9466 to the Limitations of Usual Tools section.
9467 (Limitations of Usual Tools) <sed>: Mention script length
9468 limitations with Solaris /usr/ucb/sed.
9469 <grep>: Fix wording for empty alternative. Mention that -c and
9470 -l should not be combined, and that -E and -F should not be
9473 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9474 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9476 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
9477 limits in Solaris 8 /usr/ucb/sed by testing a long script.
9479 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9481 * doc/autoconf.texi (Defining Symbols): Literal parameter of
9482 AC_DEFINE is now passed to m4_pattern_allow.
9483 * NEWS: Mention that; likewise for AC_SUBST.
9484 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
9485 the parameter to m4_pattern_allow.
9486 * tests/tools.at: Add a check for that.
9488 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9490 * lib/autoconf/status.m4: Fix typos.
9492 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9494 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
9495 only the files that this macro generates.
9497 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9499 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
9500 the HP-UX sed limitation of 99 commands, labels do not count.
9501 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
9503 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
9505 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9507 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9508 Import the following fix from coreutils:
9510 2006-01-13 Jim Meyering <jim@meyering.net>
9512 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
9513 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
9514 not double-quote uses of that variable, to accommodate the rare
9515 case in which getmntent is available in none of the libraries
9516 checked. This happens at least on FreeBSD 5.0.
9518 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
9520 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
9521 ac_config_guess, ac_config_sub, and ac_configure, since evidently
9522 some other programs unwisely rely on these undocumented vars.
9523 But put in warning comments about them.
9524 Problem reported by Ralf Wildenhues in
9525 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
9526 * NEWS: Document that these variables are intended to go away.
9528 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9530 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
9531 and set the language to C++ (analogous to the equivalent Fortran
9534 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
9535 * doc/autoconf.texi (C++ Compiler): Document it.
9536 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
9539 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
9541 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
9542 that caused config.status to generate 100-command sed scripts; the
9543 portable limit is 99.
9545 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9547 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
9548 variable `ac_d' instead of `d' to avoid infringing namespace.
9549 Report by Ralf Menzel.
9551 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
9553 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
9554 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
9555 * tests/tools.at (autoconf: subdirectories): New test, taken from
9556 the corresponding problem report by Ralf Wildenhues in:
9557 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
9559 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
9560 Quote some uses of shell variables if they might suffer unexpected
9561 globbing. This doesn't fix all instances of quoting problems that
9562 I found, just the easy ones that look safe.
9563 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
9564 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
9565 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
9566 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
9567 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
9568 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
9569 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
9571 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
9572 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
9574 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9576 * bin/autoreconf.in ($help): Reword according to the manual.
9577 Suggested by Olly Betts.
9579 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
9580 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9582 * bin/autoreconf.in: Pass the directory argument to
9583 `require_configure_ac'. Fix comment.
9584 * tests/torture.at (Configuring subdirectories): Expose this.
9585 Reported by Olly Betts.
9587 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9589 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
9590 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
9591 Automake as follows:
9593 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
9594 `$configure_in' instead of `configure.in', to preserve
9595 directory component.
9597 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9599 * config/config.guess, config/config.sub, config/texinfo.tex,
9600 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
9602 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
9604 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
9605 test for C99 conformance; (bool) 0.5 is an integer constant
9606 expression, but (bool) -0.5 is not. Problem reported by Fedor
9607 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
9609 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
9611 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
9612 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
9613 Warn about obsolete install-sh files. Remove stray sentence
9614 fragment and fix cross reference.
9615 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
9616 install -d; this undoes the 2006-05-10 change.
9617 (MKDIR_P): Mark with AN_MAKEVAR.
9618 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
9619 that we don't require $INSTALL to be thread-safe. Move comments
9620 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
9621 of AC_PROG_INSTALL. Output a message saying that we're checking
9622 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
9623 MKDIR_P instead of AC_SUBST.
9624 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
9625 Special magic for MKDIR_P, too.
9626 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
9628 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
9630 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
9632 Sync from Automake, as follows:
9634 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9635 * config/install-sh: Initialize IFS, so field splitting isn't
9637 * config/mkinstalldirs: Likewise.
9638 * config/missing: Remove superfluous quotes. Replace all uses of
9639 `[' by `test', for consistency, and for..
9640 * config/missing (sed_minuso, sed_output): New variables.
9641 (autom4te, help2man, makeinfo): Use them. Unifies detection of
9642 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
9643 Fixes `missing' to detect `--output' for help2man. Fixes
9644 PR automake/483. Report by Dennis J. Linse.
9645 (autom4te): Document in `missing --help'.
9647 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9649 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
9650 * config/install-sh: Don't use 'path' to talk about file names,
9651 as per GNU coding standards. Close a race condition reported by Ralf
9652 Wildenhues and Stepan Kasal. There is still a race condition
9653 on hosts that predate Posix 1003.1-1992, but we can't help this.
9654 Don't mishandle weird characters like space on pre-Posix hosts.
9655 Invoke mkdir at most once per dir arg on pre-Posix hosts.
9656 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
9657 AC_PROG_MKDIR_P from AS_MKDIR_P.
9658 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
9659 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
9660 earlier editions are not (including Automake 1.8.3).
9661 Do not suggest mkinstalldirs for thread-safety.
9662 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
9663 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
9664 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
9665 presence of special characters and race conditions.
9666 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
9667 in Autoconf's name space.
9669 2006-05-10 Bruno Haible <bruno@clisp.org>
9670 and Paul Eggert <eggert@cs.ucla.edu>
9672 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
9673 from Automake with minor changes.
9674 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
9676 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9678 * config/install-sh: Update to Automake CVS version, as follows:
9679 2006-04-25 Stepan Kasal <kasal@ucw.cz>
9680 * lib/install-sh: Simplify the expr implementation of dirname.
9681 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
9682 * lib/install-sh: Handle --, and diagnose unknown options.
9684 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9686 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
9687 `./autom4te' to create `./testsuite', since the `all' target
9688 will ensure its presence, but `installcheck' should not create
9689 the uninstalled wrappers.
9691 * tests/torture.at (Unusual Automake input files): Skip if we
9692 detect automake < 1.8.
9694 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9696 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
9697 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
9698 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
9701 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9703 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
9704 munge (multiple) white space and other oddities.
9705 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
9706 single quotes in variable assignment.
9707 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
9708 and similar failures by adding multiple spaces, tabs, and other
9710 Report and different test suggested by Francesco Romani
9711 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
9713 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
9714 single quotes, we only need to search for single quotes; this
9715 both simplifies the search pattern, and makes us less
9716 susceptible to `echo' variations for arguments not containing
9718 (_AC_ARG_VAR_VALIDATE): Likewise.
9720 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9722 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
9723 `$*' and IFS concatenation issue with traditional shells and
9724 bash-2.04. Report by Seanster@Seanster.com.
9726 2006-05-03 Bruno Haible <bruno@clisp.org>
9728 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
9729 precisely which Mac OS X versions have the od problem.
9731 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
9733 * doc/autoconf.texi: Use @option systematically.
9735 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
9736 and Bruno Haible <bruno@clisp.org>
9738 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
9740 (Integer Overflow): Mention the special case of integer division
9743 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9745 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
9746 traditional shells like the Solaris one that do not use the
9747 first IFS character for assembling `$*'.
9748 Prompted by a related report from autoconf_bug@nro.ca.
9750 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
9751 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9759 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
9761 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
9762 in URLs to improve DVI formatted output (requires texinfo 4.6).

9770 `action-if-found' -> `action-if-true' and similarly.
9771 (Obsolete Macros): Likewise.
9772 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
9773 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
9774 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
9776 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9778 * doc/autoconf.texi (Limitations of Make): Clean up markup.
9781 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
9784 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9786 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
9787 /bin/sh set unsorted output.
9788 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.

9797 with status 1, not merely nonzero. Clarify exit declaration.
9798 (Run Time): Move C exit status stuff to new Exiting Portably section.
9799 (Systemology): Mention Posix and levenez. Update v7 reference.
9800 (Portable Shell): Mention the Posix shell.
9802 2006-04-25 Stepan Kasal <kasal@ucw.cz>
9804 * bin/autoconf.as (me): Replace by as_me.
9806 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
9808 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
9809 since as_me isn't set yet.
9811 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
9813 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
9814 a few minor bugs in this area.
9816 * doc/autoconf.texi (Programming in M4sh): Comment out the
9817 documentation of AS_BASENAME, for now.
9818 (Shell Substitutions): Do not use AS_DIRNAME in an example.
9819 (Limitations of Builtins) <basename>: Do not refer to
9821 * bin/autoconf.as (me): Don't use AS_BASENAME.
9822 (dir): Remove the unused variable.
9823 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
9824 AS_DETECT_REQUIRED. All uses changed.
9825 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
9827 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
9828 (AS_BASENAME): Use "basename --" to protect against leading "-".
9829 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
9830 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
9831 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
9832 (_AS_DIRNAME_PREPARE): Likewise.
9833 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
9834 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
9835 (AS_DIRNAME): Use "dirname --".
9837 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
9839 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
9840 of "run time" and "run-time" changed to "runtime", for consistency.
9841 * lib/autoconf/fortran.m4: Likewise (in comment).
9842 * lib/autoconf/functions.m4: Likewise.
9843 * lib/autoconf/general.m4: Likewise.
9844 * lib/autoconf/headers.m4: Likewise.
9846 * doc/autoconf.texi (Run Time): Document the exit status situation
9847 with more accuracy and detail.
9849 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9851 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
9852 Archive is not officially `GNU' any more. Update URL.
9853 (Defining Directories): Likewise
9854 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
9856 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9858 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
9859 newline from the `trap' code to finish `config.log'; the NetBSD
9860 /bin/sh resets the exit status after an empty command, as
9861 documented in doc/autoconf.texi.
9862 Reported by Dalibor Topic <robilad@kaffe.org>.
9864 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
9866 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
9867 Suggested by Bruno Haible.
9869 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
9871 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
9872 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
9873 Instead, just list the shells that we know work.
9874 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
9875 changed. Be more cautious about the _cv_ variable.
9876 * tests/tools.at (Syntax of the shell scripts): Check the
9877 _cv_ variable once, at first, to avoid an internal autoconf error
9878 when sh -n does not work.
9880 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9882 * lib/Autom4te/FileUtils.pm: Sync from Automake.
9884 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
9886 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
9887 use ">&-" since we're only 99.999% sure that this is portable,
9888 and since the MinGW bug is fixed in a different way.
9889 * lib/autotest/general.m4 (AT_INIT): Likewise.
9891 2006-04-16 Stepan Kasal <kasal@ucw.cz>
9893 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
9894 before opening config.log, to avoid hitting a bug on MinGW.
9896 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
9898 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
9899 AS_MESSAGE_LOG_FD before reopening it onto the log file.
9900 This works around a MinGW bug reported by Eric Paire.
9901 Make sure that all writes to the log file append to it,
9902 rather than possibly losing data.
9903 * lib/autotest/general.m4 (AT_INIT): Likewise.
9905 2006-04-14 Stepan Kasal <kasal@ucw.cz>
9907 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
9910 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9914 * configure.ac (AC_INIT): Bump to 2.59d.
9916 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9920 * Makefile.maint (news-date-check): Do not require a leading `*'
9921 before the release date in NEWS.
9923 2006-04-12 Stepan Kasal <kasal@ucw.cz>
9924 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9926 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
9927 the instantiated file do not contain the string 'datarootdir'
9928 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
9929 @mandir@, replace the reference '${datarootdir}' by the value.
9930 * tests/torture.at (datarootdir workaround): New test.
9931 * NEWS: Advertise this temporary fixup.
9932 Based on a patch by Bruno Haible, reported and analyzed by
9933 Paul Eggert and Noah Misch.
9935 2006-04-12 Eric Blake <ebb9@byu.net>
9937 * tests/autotest.at (Debugging a failed test): Fix comment.
9939 2006-04-12 Stepan Kasal <kasal@ucw.cz>
9941 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
9942 all the changes since 2006-04-07.
9944 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9946 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
9947 succeeded, but `ln -s file dir' failed, take care to remove the
9948 leftover target before the next test, to prevent its spurious
9949 failure; also make sure `ln file dir' works before selecting it.
9950 Thanks to Keith Marshall for pointing this out.
9953 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
9954 assignments in `at_debug_args', so that we put them correctly
9955 in the `run' script.
9956 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
9957 Reported by Eric Blake.
9959 2006-04-11 Eric Blake <ebb9@byu.net>
9961 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
9962 top-level tests after micro-suite has been run. Used in...
9963 (Debugging a successful test, Debugging script and environment),
9964 (Debugging a failed test): ...these new tests. The first of these
9966 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
9967 macro, split out from...
9968 (AT_INIT): ...here, so that using -d also generates a run script.
9969 Document that -d inhibits top-level logging.
9970 * doc/autoconf.texi (testsuite Invocation): Document that -d only
9971 inhibits top-level logging; debug scripts are created.
9973 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
9975 * tests/autotest.at (Empty test, Empty check): New test to check it.
9977 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
9980 2006-04-10 Stepan Kasal <kasal@ucw.cz>
9982 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
9983 the files if a problem appears. Make the empty *.at files
9984 read-only, too. Proposed by Ralf Wildenhues.
9986 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9988 * config/Makefile.am: Add comment to force updated Makefile.in.
9990 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
9991 space only patch to this file, this patch causes the Makefile.in
9992 files that include freeze.mk to be updated, and thus have a
9993 newer time stamp again, which in turn makes a pristine CVS
9994 checkout have correct time stamps.
9996 * Makefile.maint (cvs-sv): New macro, to be used..
9997 (config.guess-url_prefix, config.sub-url_prefix)
9998 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
9999 point to CVS text checkout of Gnulib files.
10000 (copyright-check): Bump current year.
10001 (announcement): Do not hard-wire `./announce-gen'.
10002 (cvs-update): Propagate failures of `cvs' and `move-if-change'
10004 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
10006 (wget_files): Update config.guess, config.sub, texinfo.tex by
10007 `wget-update', now that their URLs work again.
10009 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10011 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
10012 Problem noted by Paul D. Smith.
10014 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10016 * doc/autoconf.texi: Remove unused words from word list.
10017 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
10018 .x-sc_trailing_space: New files.
10020 * doc/standards.texi: Sync from gnulib.
10022 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
10023 `LIBOBJDIR' as experimental.
10025 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
10026 with a target directory; it's internally implemented as `cp'
10027 anyway, but since Autoconf advertises the possibility to use
10028 a target directory when LN_S is `ln -s', we need to find out.
10029 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
10030 analyzed by Keith Marshall <keith.marshall@total.com>.
10034 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10036 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
10037 confdefs.h as-is. In general, if it has backslash-newline or the
10038 like, then it doesn't work either to sort or to remove empty
10041 2006-04-09 Stepan Kasal <kasal@ucw.cz>
10043 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
10045 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
10047 * lib/autom4te.in (Automake-preselections): Preselect
10050 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10052 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
10053 apostrophe within a single-quoted string, as this is the usual
10054 tradition and is easier to read than '"'"'. Don't rely on the
10055 shell treating "$/" like '$/'. Use a more-consistent indenting
10056 style for the trap.
10058 2006-04-09 Eric Blake <ebb9@byu.net>
10060 * tests/autotest.at (Backquote command substitution),
10061 (Multiline backquote command substitution): Remove mistaken
10062 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
10064 (Parenthetical command substitution, Multiline parenthetical
10065 command substitution): here.
10067 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10069 Import macros from gnulib (often changing their name).
10071 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

10097 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
10098 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
10099 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
10100 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
10101 (C Compiler): Move AC_C_LONG_DOUBLE to ...
10102 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
10103 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
10104 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
10105 (Coding Style). Don't mention m4_expand_once.
10106 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

10113 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
10114 (AC_HEADER_ASSERT): New macro.
10115 (AC_HEADER_STDBOOL): Don't assume "#error" works.
10116 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
10117 Catch a bug in an HP-UX C compiler.
10118 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.

10127 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
10129 2006-04-08 Stepan Kasal <kasal@ucw.cz>
10131 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
10132 of the warning introduced by the 2001-08-28 change.
10134 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
10135 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10137 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
10138 variables shall be overriden by the cache.
10139 * tests/torture.at (AC_ARG_VAR): Test also with a first value
10140 that contains braces.
10142 2006-04-07 Stepan Kasal <kasal@ucw.cz>
10144 Revert the patch from 2006-04-01 and only improve
10145 _AS_DETECT_BETTER_SHELL:
10147 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not

10150 only shell candidates which exist.
10151 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
10152 * lib/autotest/general.m4 (AT_INIT): No need to give three

10161 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
10162 test case by Noah Misch <noah@cs.caltech.edu>.
10164 2006-04-07 Stepan Kasal <kasal@ucw.cz>
10166 Revert my change from 2006-03-17, in other words:
10167 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
10169 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
10170 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
10173 2006-04-07 Eric Blake <ebb9@byu.net>
10175 * doc/autoconf.texi (Programming in M4sh): Document that
10176 AS_MKDIR_P exits the script on failure.
10177 * lib/autotest/general.m4: Remove redundant AS_ERROR.
10179 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10181 * config/elisp-comp, config/install-sh, config/mdate-sh,

10200 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
10201 whether `set' quotes correctly: redirect stderr of the tested
10202 `set', and use a subshell, for Ultrix; use `sed' instead of
10203 `grep' for zsh `set' which may write binary output; match only
10204 at the beginning of a line, to avoid false positives.
10205 In order to avoid false positives by unrelated variables with
10206 multiline content, put the dump algorithm in a subshell and
10207 unset all variables containing newlines (except some which are
10208 special to the shell). Warn about cache variables that are
10211 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

10216 * tests/mktests.sh: Reword comments.
10218 * tests/mktests.sh: Only skip internal macros starting with
10219 `_AC_' or `__AC_'. Noted by Stepan Kasal.
10220 Update exclusion lists for the test suite to this end:
10221 (AC_ARG_VAR): Do test this now.
10222 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
10223 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
10224 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
10225 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
10227 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
10228 shell issue with double-quoted command substitutions of native

10250 * tests/Makefile.am (maintainer-check-posix):
10251 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
10253 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
10254 ac_config_<foo>s again, sometimes normalized, sometimes not.
10255 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
10256 (AC_CONFIG_COMMANDS): Do not do so here.
10257 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
10258 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
10259 2005-07-25 rewrite. Noticed by Noah Misch.
10261 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define

10265 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
10266 inside m4_expand_once; it is redundant.

10269 for --help from Cygnus `configure.'
10271 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

10303 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
10304 empty test suite works.

10310 TAGS to ac_config_<foo>s.
10311 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
10312 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
10313 normalizing it, consistent it with previous releases.
10314 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
10316 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>

10324 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
10325 Use 'comm' rather than N instances of grep; this also fixes a bug
10326 whereby substrings were incorrectly matched, causing us to not
10327 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
10328 (exclude_list): Exclude empty macros.
10329 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

10412 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10413 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set

10416 initial `rm' of the candidate files...
10417 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10418 the same list in subsequent `rm' calls, and for the temporary
10419 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10420 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10421 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10422 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10423 no longer needed) by libtool. Make it a cache check.
10424 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10425 copied here by mistake.

10502 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
10503 switch all of them on and of when necessary. Fixes the bug when

10554 * bin/autoscan.in: The value of find_configure_ac should be
10555 checked for existence, so we don't barf over a nonexisting
10556 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
10558 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

11052 rather than "sed" when talking about Sed in general.
11053 (Particular Programs): Likewise.
11054 (Coding Style): y is like s with respect to / and ,.
11055 (Limitations of Usual Tools): Document the weird restrictions
11056 that Posix has about { }. Use better quoting.
11057 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_HEADER):
11058 Rewrite to conform to Posix rules about { } in sed scripts.
11059 * lib/m4sugar/m4sh.m4 (AS_DIRNAME_SED, AS_BASENAME_SED): Likewise.
11060 * tests/foreign.at (Libtool): Likewise.
11061 * tests/semantics.at (AC_CHECK_PROG & AC_CHECK_PROGS):

11079 2005-12-31 Stepan Kasal <kasal@ucw.cz>
11081 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Use $PATH_SEPARATOR;
11082 ":" caused problems on OS/2-EMX. Suggested by Andrew Belov.
11084 2005-12-29 Paul Eggert <eggert@cs.ucla.edu>
11086 * doc/autoconf.texi (Shell Substitutions): Warn about unbalanced

11120 CONFIG_SHELL in the environment of the configure rerun.
11121 * doc/autoconf.texi (Here-Documents, config.status Invocation):
11122 Suggest passing CONFIG_SHELL absolute, and in the environment
11123 rather than as option.
11125 2005-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11127 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

11143 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
11144 Factor functionality to..
11145 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
11146 `AC_SUBST($1)' in the public version.
11147 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
11148 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
11151 2005-11-01 Stepan Kasal <kasal@ucw.cz>
11153 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3

11168 conftst2.$ac_objext.
11169 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
11171 2005-10-24 Stepan Kasal <kasal@ucw.cz>
11173 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
11174 conftest.o, to see whether the compiler really obeys; rm the object
11175 file before and after the test and register it with ac_clean_files.
11176 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
11178 2005-10-21 Stepan Kasal <kasal@ucw.cz>
11180 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
11181 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
11182 code so that the most common case requires less forks.
11184 2005-10-20 Stepan Kasal <kasal@ucw.cz>

11196 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
11198 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
11199 AC_LANG_PROGRAM, fixing a typo. Don't give details about
11200 the inner workings of AC_LANG_FUNC_LINK_TRY.
11201 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
11202 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
11203 by the function rather than ignoring it.
11204 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
11205 comparing its address. Intel's interprocedural optimization was
11206 outsmarting the old heuristic. Problem reported by
11209 2005-10-19 Stepan Kasal <kasal@ucw.cz>
11211 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

11216 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
11218 2005-10-04 Stepan Kasal <kasal@ucw.cz>
11220 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
11221 before removing it (chmod -R u+rwx); there are three instances of this.
11223 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11224 Stepan Kasal <kasal@ucw.cz>
11226 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
11227 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
11228 make its content writable before removing it. Remove an errorneous
11229 comment from the end, where the logs of the failed tests are copied
11230 to the main log file.
11232 2005-09-27 Stepan Kasal <kasal@ucw.cz>
11234 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
11235 in case the computer is too quick. Double quote the configure.ac
11238 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
11239 problems if the testsuite were running too fast.
11241 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
11243 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
11244 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
11245 (which belong to Xt, not X itself). See Debian bug 327655.
11246 * NEWS: Mention this.
11248 2005-09-07 Stepan Kasal <kasal@ucw.cz>
11250 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
11252 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
11254 * config/move-if-change: Don't output "$2 is unchanged";
11255 suggested by Ben Elliston. Handle weird characters correctly.
11257 2005-09-06 Stepan Kasal <kasal@ucw.cz>
11259 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
11260 calls, so that the final expansion of this macro is shorter.
11261 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
11262 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
11263 the cleanup there. Use AS_VAR_* macros, to be more general.
11264 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
11266 * lib/autoconf/general.m4: Use AS_IF where appropriate.
11268 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
11270 2005-09-01 Stepan Kasal <kasal@ucw.cz>
11272 * doc/autoconf.texi (Configuration Headers): Add an index entry
11275 2005-08-26 Pavel Roskin <proski@gnu.org>
11277 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
11278 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
11281 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
11283 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
11284 The previous patch didn't work, so try a better one.
11286 2005-08-26 Stepan Kasal <kasal@ucw.cz>
11288 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
11289 in the example. Reported by Bruno Haible.
11290 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
11291 "if $undefined_var;" succeeds with my shell.
11293 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
11294 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
11295 but change the m4_divert_text to m4_divert_once.
11297 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
11299 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
11300 Work around bug in Solaris /usr/xpg4/bin/awk.
11301 The bug is present in at least Solaris 8 through 10.
11303 2005-08-24 Stepan Kasal <kasal@ucw.cz>
11305 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
11306 some evil values and relying on the fact that $* concatenates the
11307 parameters by the first character from IFS.
11309 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
11310 Stepan Kasal <kasal@ucw.cz>
11312 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
11313 first header appears, define AH_HEADER.
11314 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
11315 Update limitations about when to call AC_CONFIG_HEADERS.
11316 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
11317 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
11318 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
11319 ``Configuration Actions''; fix their index entries.
11321 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
11322 options correctly. Process N-M as M-N if M is smaller than N.
11323 Process ranges correctly so that N-N will run only N.
11324 Sort and uniquify the tests that will be run. If there is more
11325 than one test, reinsert the banners for the tests.
11326 * tests/autotest.at (Keywords): Unmark XFAIL.
11328 2005-08-23 Stepan Kasal <kasal@ucw.cz>
11330 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
11331 before passing the macro name to AH_TEMPLATE.
11333 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
11334 now opens log after option processing; in particular, --version
11335 and --help do not touch config.log.
11337 * Makefile.maint: Revert the change from 2005-08-12.
11339 2005-08-22 Stepan Kasal <kasal@ucw.cz>
11341 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
11343 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
11345 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11347 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
11348 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
11351 * doc/autoconf.texi (Defining Symbols, Changed Results):
11352 Prepend to LIBS, not append, in examples.
11354 2005-08-16 Stepan Kasal <kasal@ucw.cz>
11356 When building in place, set srcdir="."; suggested by Tim Van Holder.
11358 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
11359 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
11360 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
11361 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
11362 does not mean "no --srcdir option".
11364 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11366 * tests/autoscan.at (autoscan): New file.
11367 * tests/suite.at: Use it.
11368 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
11369 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
11371 * tests/autotest.at (Keywords): Test keywords combinations.
11373 2005-08-12 Stepan Kasal <kasal@ucw.cz>
11375 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
11376 add "2>&1"; gzip 1.2.4 prints help on stderr.
11378 2005-07-27 Stepan Kasal <kasal@ucw.cz>
11380 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
11381 was pushdef'ed twice while popped only once. Push it only once.
11382 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
11384 2005-07-26 Stepan Kasal <kasal@ucw.cz>
11386 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
11387 prefixed by mere "===", not "configure: === ".
11389 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
11391 * Makefile.maint: Update from Bison.
11393 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
11394 "<tab>" in comment, so that the point is understandable.
11396 2005-07-25 Stepan Kasal <kasal@ucw.cz>
11398 Rewrite substantial part of lib/autoconf/status.m4.
11399 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
11400 and CONFIG_COMMANDS are not processed in four separate loops.
11401 Instead, there is one main loop. This alows that the common code
11402 is expanded only once, thus config.status (and configure) is smaller.
11404 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
11405 the AC_LIST_FILES and cousins macros are no longer used.
11407 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
11408 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
11409 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
11410 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
11411 contain the initialization, nor the for loop, nor the associated
11412 commands; all these go to ...
11413 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
11414 _AC_OUTPUT_CONFIG_STATUS.
11415 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
11416 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
11417 (_AC_OUTPUT_FILE): The creation of the sed script ...
11418 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
11419 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
11420 _AC_OUTPUT_MAIN_LOOP.
11421 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
11422 _AC_CONFIG_COMMANDS): Use ...
11423 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
11424 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
11425 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
11426 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
11427 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
11428 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
11430 (_AC_CONFIG_UNIQUE): Update.
11431 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
11432 Replaced by this ...
11433 (_AC_LIST_TAGS): ... new common macro.
11434 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
11435 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
11436 (_AC_LIST_TAG_COMMANDS): ... new common macro.
11437 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
11438 this didn't belong to the `config commands' section.
11439 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
11440 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
11441 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
11442 to the `config commands' section either.
11443 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
11444 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
11446 ... and many changes to the comments nearby.
11448 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
11449 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
11450 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
11451 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
11452 (#define header templates): The comment at the top of the generated
11453 header now includes the name(s) of the source file(s).
11455 Several unrelated small changes:
11457 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
11458 parameter to AC_DIAGNOSE.
11459 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
11460 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
11461 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
11462 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
11463 with AU::AC_OUTPUT.
11464 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
11465 in AC_OUTPUT doesn't double-quote it either.
11466 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
11469 2005-07-10 Stepan Kasal <kasal@ucw.cz>
11471 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
11472 versions of Portland Group compiler produce single- and double-quoted
11473 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
11474 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
11476 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
11478 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
11479 This is a corrected version of yesterday's patch.
11481 2005-07-07 Stepan Kasal <kasal@ucw.cz>
11483 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
11484 path, too; insert a "===" to emphasize the line.
11486 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
11487 ac_cv_build_alias to ac_build_alias.
11488 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
11490 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
11491 change eliminates it. Problem reported by Alexandre Duret-Lutz.
11492 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
11493 (AC_ARG_VAR): ... here.
11494 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
11497 Keep a list of all precious variables and process them with one simple
11498 for loop, instead of expanding all commands, or, OTOH, complicated
11499 processing of output of "set".
11500 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the

11507 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
11508 its value to shell variable ac_precious_vars and call
11509 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
11510 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
11511 _AC_ARG_VAR_VALIDATE.

11536 Fix my changes from 2005-07-01; reported by Noah Misch.
11537 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
11538 description, the macro now accepts only a single tag.

11541 Fix cases when the varsions of Autoconf and Autotest don't match.
11542 Reported by Noah Misch.

11556 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
11557 sed substitution command, so that we allow | in program prefixes

11568 for loop over config.site files using `set', to allow
11569 directory names containing IFS characters.
11571 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
11573 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
11574 directories with weird names. Apparently some people like living

11595 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
11596 document to output the default config_* lists to config.status.
11597 Don't recognize option --file, if the functionality is not there.
11598 Likewise for --header; moreover, recognize --he and --h as shortcuts
11599 for --help in that case.
11601 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
11602 matches the order of execution. No code changed.

11624 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
11625 (AC_SUBST): Call it.
11626 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
11627 the directory specific variables; but don't call it for configure_input.
11629 2005-06-28 Derek Price <derek@ximbiot.com>
11631 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
11634 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
11636 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
11637 directory have inherent problems with special characters like spaces,
11638 due to limitations in Make syntax. Problem reported by Alexandre
11640 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
11641 Also, fix Tru64 porting problem with shell patterns,

11653 from Justace Clutter.
11654 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
11655 variable into diagnostic. Make the diagnostic an error, not a warning,
11656 because we really don't support spaces and suchlike in dir names.
11657 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
11658 Don't worry about backslashes in srcdir; it can't happen now.

11669 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
11671 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
11672 that '\|' is not allowed in BREs; recommend using newline separated

11686 b, t, r, w commands require single space, while : cannot have any.
11687 (Special Shell Variables): Fix sed code this in the example.
11688 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
11689 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
11691 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
11692 expand to the empty list. Don't use two pairs of m4_changequote,
11693 it's not necessary.
11695 2005-06-20 Derek Price <derek@ximbiot.com>
11697 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.

11701 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
11702 * doc/autoconf.texi:
11703 Don't mention Solaris versions so much, if a
11704 problem is common to all extant versions of Solaris. Say "SunOS
11705 4" instead of "SunOS" for SunOS 4.
11706 (awk): Mention more of the limitations of traditional Awk.
11707 (cat): Don't talk about cat -v.
11709 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
11711 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.

11720 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
11721 Use shell builtins rather than 'expr', to work around expr bug.
11723 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
11725 * doc/autoconf.texi: "filesystem" -> "file system".

11735 (.x.1): Ignore the time stamp in the .TH line when deciding whether
11736 to update the man page. That way, we don't have to check in new
11737 man pages every month.
11739 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
11740 quotes and backslashes. Patch from Derek Price.

11749 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
11750 -u, since it outputs chatter if the input files are the same.
11751 Problem reported by Ralf Menzel.
11753 2005-06-08 Derek Price <derek@ximbiot.com>
11755 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
11756 renaming them since they are about to be redefined anyhow.
11758 2005-06-08 Derek Price <derek@ximbiot.com>
11760 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
11761 redefined M4 macros to this node. Document m4_include & m4_sinclude.
11762 Move m4_undefine to alphabetical order.
11764 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
11766 * README: Recommend GNU M4 1.4.3 or later.
11767 * doc/autoconf.texi (Introduction): Likewise.
11768 Reword to avoid some formatting glitches.
11769 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
11770 Clarify explanation of HP compiler bug.
11771 Redo example output tp match current CVS snapshot.
11772 Use @example.org in email addresses when the examples
11773 might get inadvertently cut-and-pasted into user code.
11774 Remove example of autom4te usage that doesn't seem to work now.
11775 Use modern AC_INIT (except when the example is meant to be
11776 shown with Autoconf 2.13).

11786 follows its own advice about quoting better.
11787 Reword to avoid some formatting glitches.
11788 * doc/installt.exi: Reword to avoid some formatting glitches.
11790 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
11791 Tru64 ksh pattern matching bug. Reported against Libtool by
11792 Albert Chin <libtool@mlists.thewrittenword.com> and
11793 Nicolas Joly <njoly@pasteur.fr>.
11795 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11797 m4_cdr of one-member list was [[]] (one-member list containing an
11798 empty string) instead of [] (an empty list. Callers were skewed to
11799 match this misbehaviour. As a consequence of this:
11800 - m4_foreach([x], [], [foo]) expanded to `foo', while
11801 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
11802 This bug has been fixed:
11804 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
11805 expand to an empty string; print error msg if called without
11807 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
11808 misbehaviour; handle [] and [[]] correctly.
11810 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11812 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
11813 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
11814 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
11816 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
11818 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
11819 swallow records with more than 99 fields.
11820 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
11821 parse the long line.
11823 2005-06-04 Stepan Kasal <kasal@ucw.cz>
11825 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
11826 swallow literals longer than 399. Reported by Ralf Wildenhues.
11827 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
11828 to workaround this limitation.

11844 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
11845 expression of unbounded size when processing the --list
11846 option. This runs afoul of a limit of 399 bytes per regular
11847 expression on AIX. Problem reported by Ralf Wildenhues.

11858 2005-05-31 Dan Manthey <dan_manthey@partech.com>
11860 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
11861 now contain newlines, and substituted files must be referenced on
11862 a line alone; the sed scripts to substitute them are now very
11864 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
11865 commands can be put in a sed script portably.
11866 * doc/autoconf.texi (Setting Output Variables): Document above
11867 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple

11878 * tests/local.at: Don't attempt to check for negated character
11879 classes in shell scripts. The test was too brittle.
11881 2005-05-25 Stepan Kasal <kasal@ucw.cz>
11883 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

11897 messages when ac_unique_file is not found.
11898 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
11899 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
11900 commands, for consistency with AC_MSG_ERROR and such.

11916 (ac_top_builddir): ... this ...
11917 (ac_top_build_prefix): ... to this; the old name is also kept, for
11918 backward compatibility.
11919 (ac_top_builddir_sub): New variable, without the trailing slash,

11935 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
11936 argument to m4_foreach. I guess it was necessary in the past,
11937 but I think it's a no-op now.

11941 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
11942 ``cat <<_ACEOF'' commands to one.

11950 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
11951 the wrong patterns between ``case'' and ``esac.'' The previous
11952 code had false positives.

12016 abbreviations of --version and --debug.
12018 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
12020 * doc/autoconf.texi (Autoconf Language): Be more precise about
12021 quoting rules. Problems noted by Stepan Kasal.
12022 Also, throughout this document, be more careful about white space.
12023 "blank", "white space", and "space" all have different meanings
12024 and we should be careful to say what we mean.
12026 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
12028 Fix C++ related problems reported by Werner Lemberg.

12037 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12039 * doc/autoconf.texi (Generic Functions): Typos.
12041 2005-05-02 Gary V. Vaughan <gary@gnu.org>
12043 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
12044 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
12045 set by latest automake.
12047 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
12049 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
12050 outputs 0 on GNU/Linux these days.
12052 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
12054 * doc/autoconf.texi (Autoconf Language): Add more description
12055 about quoting heuristics.
12056 (Limitations of Builtins): Describe "set -" problems.
12058 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12060 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
12063 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
12064 by AC_DEFINE; it was a mistake.
12065 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
12067 2005-04-25 Stepan Kasal <kasal@ucw.cz>
12069 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
12071 2005-04-22 Stepan Kasal <kasal@ucw.cz>
12073 * doc/autoconf.texi (External Software): Quadrigraphs are not
12074 processed correctly in AS_HELP_STRING; avoid this in the examples.
12075 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
12076 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
12077 comment and reduce m4_default([foo], []) to [foo].
12078 (m4_strip): Update the explanation.
12080 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
12082 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
12083 Remove core.conftest.* too; it's generated by Tru64 5.1.
12084 Problem reported by Jennis Pruett.
12085 * lib/autoconf/functions.m4
12086 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
12087 Don't bother to remove core files; AC_RUN_IFELSE should do that
12090 2005-04-19 Stepan Kasal <kasal@ucw.cz>
12092 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

12106 * doc/autoconf.texi (External Software, Package Options): Add
12107 examples showing how to implement --with-* and --enable-* options.
12109 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
12111 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
12112 as well as configure.in. Problem reported by Gregorio Guidi.
12114 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
12116 * doc/autoconf.texi (Particular Functions): Use gnulib's current
12117 pattern for alloca snippet.

12127 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
12129 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
12130 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
12132 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12134 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
12135 Merge `-z option' as well for the benefit of Solaris link flags. Pass
12136 whole-archive (-zallextract, -zdefaultextract) options in the hope of
12137 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
12138 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
12140 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
12142 * NEWS: The configure command now warns you if you attempt to use
12143 a directory whose name contains a special character like space,
12145 * doc/autoconf.texi (Installation Directory Variables): Allow
12146 "," in file names. Do not use \@; it's not a portable regexp.
12147 * bin/Makefile.am (edit): Likewise.
12148 * lib/Makefile.am (edit): Likewise.
12149 * tests/Makefile.am (edit): Likewise.
12150 * tests/semantics.at: Likewise.
12151 * tests/torture.at: Likewise.
12152 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
12153 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
12154 * doc/autoconf.texi (File System Conventions): Warn about
12155 unportable file names.
12156 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
12158 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
12159 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
12160 ac_pwd, and quote srcdir.
12161 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
12163 * doc/autoconf.texi: Fix some systematic formatting problems.
12164 ".)" needs a following @: if not at the end of a sentence, and
12165 similarly for "!)". "etc." should be preceded by a comma.
12166 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
12168 2005-03-22 Bruno Haible <bruno@clisp.org>
12170 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
12171 argument is often called 'build-aux'.
12173 2005-03-07 Stepan Kasal <kasal@ucw.cz>
12175 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
12176 macro AC_TRY_LINK is obsolete.
12177 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
12180 2005-02-24 Stepan Kasal <kasal@ucw.cz>
12182 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
12183 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
12184 from a Common Lisp's `cl'.
12185 (AC_PROG_CXX): Behave according to the documentation: don't
12186 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
12187 make the variable CCC precious; use `cl.exe', not `cl'.
12189 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12190 Alexandre Duret-Lutz <adl@gnu.org>
12192 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
12193 /dev/null, as "configure" shouldn't read stdin, and this insulates
12194 us from problems (e.g., when testing for "cl"). Also, do this
12195 redirection before invoking "hostname" or "uname", and keep the
12196 original input stream available via...
12197 (AS_ORIGINAL_STDIN_FD): ... this new macro.
12198 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
12199 bother with "</dev/null" since it's now done at the top of
12201 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
12202 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
12203 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
12204 * doc/autoconf.texi (File Descriptor Macros): New section.
12205 (Printing Messages): Mention it.
12206 * tests/base.at (Input/Output): New test.
12208 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12210 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
12211 newline if neither \c nor -n work, as that would output two
12212 newlines. Prefer -n to \c. Reported by Stepan Kasal.
12214 2005-02-12 Stepan Kasal <kasal@ucw.cz>
12216 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
12217 This causes that any required macros inside will get before the if.
12218 * doc/autoconf.texi (autom4te.cache): A typo.
12220 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
12222 Undo previous change, except keep the change to
12223 lib/autoconf/programs.m4 that replaced grep with shell
12224 pattern-matching. This is because net-snmp configure reads stdin.
12225 Reported by Noah Misch.
12227 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
12229 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
12230 from /dev/null, as "configure" shouldn't read stdin, and this
12231 insulates us from problems (e.g., when testing for "cl").
12232 Suggested by Alexandre Duret-Lutz. Also, do this redirection
12233 before invoking "hostname" or "uname".
12234 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12235 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
12236 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
12237 "</dev/null" since it's now done at the top of 'configure'.
12238 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
12239 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
12240 Also, replace grep with shell pattern-matching, to save a process.
12242 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
12244 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12245 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
12246 avoid thinking that Allegro Common Lisp's "cl" command is a C++
12249 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
12251 * doc/autoconf.texi (Limitations of Usual Tools): Document that
12252 grep -q isn't portable. Improve grep -s explanation.
12253 Problem reported by Dan Manthey.
12255 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
12257 * doc/autoconf.texi (Special Shell Variables): Clarify
12258 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
12260 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
12262 * doc/autoconf.texi: Use @acronym for DJGPP.
12263 Fix some @code's that should have been @env's, and vice versa.
12264 Sort environment variable names.
12265 Mention that shells no longer inherit IFS.
12266 Don't recommend PATH_SEPARATOR=';' so strongly.
12267 Mention that $RANDOM might expand to the empty string.
12268 "symlink" and "soft link" -> "symbolic link".
12269 Improve mktemp description (reported by Bruno Haible).
12271 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
12273 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
12274 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
12276 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
12279 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
12281 * NEWS: Mention AT_COPYRIGHT.
12283 * tests/local.at (AT_CMP): Use diff directly on input files rather
12286 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
12287 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
12289 2005-02-04 Noah Misch <noah@cs.caltech.edu>
12290 and Paul Eggert <eggert@cs.ucla.edu>
12292 * tests/autotest.at (Empty test suite): New test.
12293 * tests/torture.at (Substitute and define special characters)
12294 (Substitute a 2000-byte string, Define to a 2000-byte string)
12295 (Substitute a newline, Define a newline): New tests.
12297 2005-02-04 Noah Misch <noah@cs.caltech.edu>
12299 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
12300 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
12301 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
12302 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
12303 (Standard regular expressions): New test.
12304 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
12305 excess test name quoting.
12306 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
12307 CPPFLAGS to `configure' instead of setting it in `configure'.
12309 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
12310 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
12313 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
12314 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
12316 * tests/local.at (AT_CMP): New macro.
12317 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
12318 (AC_SAVE_STATE): Move environment grep...
12319 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
12320 (AT_CONFIG_CMP): New macro.
12321 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
12322 * tests/c.at (Extensions): Do not exit early.
12323 * tests/atlocal.in: Inherit $GREP.
12325 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
12326 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
12328 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
12329 (AC_COPYRIGHT): Factor header comment portion out and move into...
12330 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.

12342 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
12344 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
12345 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
12347 Try not to generated lines of unlimited length, as POSIX places a
12348 2047-byte limit on line length of portable text files.
12349 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
12350 Use newline as a separator, not space.

12352 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
12355 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12357 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
12358 as_func_*. Add test to check whether positional parameters
12359 are restored after function return.
12361 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
12363 * doc/autoconf.texi (Special Shell Variables): Mention _,
12364 BIN_SH, DUALCASE. Say that variables other than "status" are safe
12365 if they contain a lower-case letter. The DUALCASE problem was
12366 reported by Ralf Wildenhues.
12368 * bin/autoconf.as: Don't exit with status 0 after write failure
12369 with --help or --version.
12370 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
12371 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
12373 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

12408 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
12409 Update the long comment explaining it.
12411 m4_require no longer writes an ``is required by'' line to the
12412 execution stack. It contains only one bit of non-redundant
12413 information: that the macro was required, not called. And even
12414 this bit is useless in most situations: have you ever met a macro
12415 which both calls and requires the same macro?
12417 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
12418 (_m4_defun_pro_outer): ... only via this macro, for the outermost

12425 (_m4_require_call): Use it.
12426 * tests/m4sugar.at (m4_require): Expect output without the
12427 ``is required by'' messages.
12429 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
12431 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
12432 rather than x for expr.

12463 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
12465 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
12466 Warn about newline stripping in `` and $(). Update Solaris

12493 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
12495 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>

12522 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
12523 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
12524 stored in _m4_divert_diversion or _m4_divert_dump.
12525 (m4_divert_pop): When the parameter is given, compare the symbolic
12526 name with the last diversion pushed on the stack. Previously, the
12527 current diversion was compared with the numeric value of the
12528 diversion given as the parameter.
12529 (m4_require): If the macro hasn't been expanded yet, call ...
12530 (_m4_require_call): this new macro.

12563 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

12823 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Check libc before
12824 looking elsewhere for getmntent. Problem reported by Mark D. Baushke.
12825 * doc/autoconf.texi (Particular Functions): Mention new behavior.
12827 2004-12-03 Stepan Kasal <kasal@ucw.cz>
12829 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
12830 out the common code to ...
12831 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
12832 value of the #define--default to 1, iff the macro was called
12833 with exactly one parameter.
12835 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
12837 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
12838 "char c = '\200';" rather than "char c = 0x80;" as the
12839 latter doesn't conform to the strict C standard due to
12840 overflow on signed char hosts.
12842 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
12843 to -qlanglvl=ansi. We don't want to disable extensions.
12845 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
12847 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
12848 (Using Autotest, testsuite Scripts, Writing testsuite.at):
12849 Reword slightly to avoid some English-language problems noted

12903 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
12904 the $1_found variable, don't test whether the file is executable;
12905 Both things are checked ...

12920 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
12922 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed

12942 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
12943 Problem reported by Stepan Kasal.
12945 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
12947 Fix problems reported by Andreas Buening in:
12948 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
12949 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
12951 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
12952 readable; it's not true in OS/2-emx.
12954 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
12956 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
12957 "/usr/include", clear ac_x_includes instead of leaving it as "no"
12958 (trivial change). Problem and patch reported by Andrew Church in:
12959 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
12961 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

12989 texinfo.tex for now (done by hand now).
12990 * Makefile.maint (wget_files, cvs_files):
12991 Remove ansi2knr.c; nobody uses it.
12992 (ansi2knr.c-url_prefix): Remove.
12993 (cvs-update): Fix test for failure. I don't know why it ever
12996 * doc/autoconf.texi: Update URLs, some of which went stale.
12997 Use @uref rather than @href.
12999 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
13000 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
13002 * config/config.guess, config/config.sub, config/elisp-comp,
13003 config/install-sh, config/mkinstalldirs, config/texinfo.tex,

13013 tests/tools.at, tests/torture.at:
13014 Use "file name" rather than "filename" or "path",
13015 to be consistent with the terminology of the GNU coding standards.
13017 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
13019 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
13020 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
13021 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
13022 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
13024 More fixes to support spaces in the name of the build directory.
13025 This isn't a complete fix but it's an improvement.
13027 * bin/autoconf.as (autom4te_options): New var.
13028 Use it instead of appending to AUTOM4TE, so that we can allow
13029 spaces in the build directory's absolute name.
13030 * bin/autoheader.in ($autoconf): Allow spaces in file names.
13031 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
13032 AT_CHECK_NOESCAPE): Likewise.
13033 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
13034 main program): Likewise.
13036 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
13038 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

13044 * doc/autoconf.texi (Function Portability): Document isinf and
13045 and isnan. From a suggestion by Kevin Ryde.
13047 * lib/Autom4te/General.pm (END): Return correct exit status even
13048 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
13050 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
13052 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
13053 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
13054 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
13056 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
13058 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
13059 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
13060 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
13061 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
13062 * lib/autom4te.in (Automake-preselections): Preselect
13063 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
13065 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
13067 * lib/autom4te.in (Automake-preselections): Preselect
13068 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
13071 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
13073 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for

13076 Document problem with "`""`" in pdksh POSIX mode.
13078 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
13080 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
13081 with pdksh, too. Problem reported by Patrick Welche via
13083 * doc/autoconf.texi (Shellology): Note that set -o posix is
13084 useful for pkdsh, too.
13086 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
13088 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
13089 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
13090 Don't fail if ENV or BASH_ENV is readonly.
13091 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
13092 etc. are read only. Problem reported by Ludovic Courtes.
13094 2004-06-23 Noah Misch <noah@cs.caltech.edu>
13096 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
13097 zsh, disable GLOB_SUBST to avoid backslash handling problems.
13100 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
13102 * doc/autoconf.texi (File System Conventions): Warn about
13103 names like "aux". Problem reported by Eric Blake.
13105 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
13106 by zero instead of array size, so that we can use any arithmetic
13107 constant expression (instead of requiring an integer constant
13108 expression). This allows us to test expressions like DBL_MAX <
13109 LDBL_MAX, which didn't conform to the C standard using the old
13111 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
13112 now that we can do floating-point tests at compile time.
13114 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
13116 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
13117 and LDBL_EPSILON, as the resulting expression isn't an
13118 integer constant expression and violates the C standard.
13119 Problem reported by Nelson H. F. Beebe. Also, check
13120 for "L" suffix, and check that long double doesn't have
13121 worse range or precision than double, that mixed-mode
13122 arithmetic doesn't generate a diagnostic, that double
13123 constants fit in long double.
13125 2004-06-03 Kevin Ryde <user42@zip.com.au>
13127 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
13128 malloc(0) and realloc(NULL,size).
13130 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
13133 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
13135 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
13136 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
13139 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
13141 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
13142 can be rewritten using if-then-else. Suggested by Bruno Haible.
13144 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
13146 * doc/autoconf.texi (testsuite Scripts): Fix typo.
13147 Problem reported by Stepan Kasal.
13149 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
13151 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
13152 change). Patch reported by Ralf Wildenhues in
13153 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
13155 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
13156 function F exists if the compiler and linker let you compile an
13157 expression like (F != 0). Recent versions of GCC optimize away
13158 the reference to F in that case, since every function address must
13159 be nonzero, so the link succeeds even if F does not exist.
13160 Problem reported by Manu in
13161 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
13163 * doc/autoconf.texi (Systemology): Standardize on the spelling of
13164 "Unix". Many uses changed.
13165 (Limitations of Builtins): Explain better why the ! command isn't
13168 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
13170 * lib/autom4te.in (Automake-preselections): Preselect
13171 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
13173 2004-05-19 Kevin Ryde <user42@zip.com.au>
13175 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
13176 referencing AC_FUNC_STRERROR_R.
13178 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
13179 note pessimistic assumption when cross compiling.
13181 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
13183 * doc/autoconf.texi (Limitations of Make): Note that BSD make
13184 (until 2004) invoked subcommands with sh -e, contra POSIX.
13185 Reported by Kevin Ryde.
13187 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
13189 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
13190 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
13191 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
13192 `test -f " /usr/bin/grep"', which _always_ failed.
13193 (AC_PROG_SED): Ditto bogus PATH fix.
13194 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
13195 requires that grep correctly supports _multiple_ `-e' options, rather
13196 than stating only that grep should accept `-e'.
13198 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
13200 Port to C99, which requires that 'exit' be declared.
13202 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
13203 to ensure that stdlib.h is included.
13204 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
13205 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
13206 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
13207 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
13208 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
13209 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
13210 when using 'exit' in a test; C99 requires that 'exit' be declared.
13212 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
13214 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
13215 now prefers 'grep' implementations that accept -e.
13216 (Limitations of Usual Tools): Describe problems of traditional
13217 egrep and fgrep with long input lines, and of traditional grep
13219 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
13220 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
13221 All callers changed. Append /usr/xpg4/bin to the PATH, for
13223 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
13224 the user with complaints about multiple -e options.
13225 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
13226 Define it with AC_PROG_GREP.
13227 * configure.ac (AC_PROG_GREP): Add.
13228 * lib/freeze.mk (GREP): New macro.
13230 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
13232 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
13233 a possible candidate only after all others fail, rather than
13234 consulting it first. This improves backward compatibility by
13235 better reflecting the way shell selection occurred in previous
13236 versions of Autoconf, and should help to avoid triggering latent
13237 problems in other packages, such as the one in Automake where zsh
13238 is not handled robustly:
13239 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
13240 Although it is not Autoconf's responsibility to work around
13241 problems in Automake, it nevertheless makes sense to avoid
13242 introducing unnecessary incompatibilites.
13244 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
13245 Gary V. Vaughan <gary@gnu.org>
13247 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
13248 how deeply nested we are when a suitable tool is found, set the
13249 ac_path_TOOL_found flag.
13250 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
13251 nested we are in this macro. Break out of all 3 nested loops if
13252 ac_path_TOOL_found is set.
13254 2004-04-21 Gary V. Vaughan <gary@gnu.org>
13256 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
13257 of the _AS_PATH_WALK loop too if GNU flavor is found.
13259 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
13261 * doc/autoconf.texi (Limitations of Make): Update documentation
13262 for `$<'. New entry `Long lines', based on a report from Simon
13263 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
13264 paragraph about DJGPP, based on a mail from Richard Dawe.
13266 2004-04-20 Paul Eggert <eggert@twinsun.com>
13268 * tests/c.at (C keywords): Don't assume that GCC supports
13269 "restrict" and "inline", as sufficiently-old GCC versions do not
13270 (also, GCC configured to be in pedantic C89 mode does not).
13271 Problem reported by Sumit Pandya in:
13272 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
13274 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
13275 consider -g to work if it generates warnings when plain compiles
13276 don't. Problem reported by Braden McDaniel in:
13277 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html

13290 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
13291 best tool so far counter rely on the tool path variable name to
13292 avoid checks for one tool being affected by the results of running
13293 the length check on a previous tool.
13295 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
13296 match expression argument, as different greps have different
13297 regular expression flavours.

13328 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
13329 now defines HAVE_DECL_TZNAME if it is declared, when
13330 HAVE_STRUCT_TM_TM_ZONE is not defined.
13331 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
13332 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

13401 * bin/Makefile.am (edit): Don't use $< in a context where
13402 POSIX doesn't require support for it. Use $@.in instead.
13403 Problem reported by Anthony N. Frasso in
13404 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

13420 Fix a dependencies problem, stemming from a Autoconf 2.59 build
13421 problem on QNX reported by Stephen Rasku in
13422 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
13424 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
13425 $(m4sh_m4f_dependencies); this removes a FIXME.
13426 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
13427 (MAINTAINERCLEANFILES): Split into pieces,
13428 one per related section. Add $(srcdir)/wrapper.in.
13430 2004-02-09 Paul Eggert <eggert@twinsun.com>
13432 * doc/autoconf.texi (Setting Output Variables): Emphasize that
13433 AC_SUBST provides no portable way to escape literal newlines.
13435 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
13436 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
13437 Darwin uses -lcrt2.o and there's little point to cataloging all
13438 the system variants. Partial fix reported by Andreas Waechter in:

13464 Paul Eggert <eggert@twinsun.com>
13466 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
13467 (AS_INIT): Output shell initialization there. Removed optional
13468 parameter. Expand _AS_SHELL_FN_SPY.

13477 (_AS_RUN): Move it here, support testing with eval.
13478 (AS_REQUIRE_SHELL_FN): Require shell functions when

13481 trigger the bash bug anymore.
13482 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
13483 use AS_INIT_WITH_SHELL_FN.
13484 * bin/autoconf.in, tests/wrapper.in: Regenerated.
13486 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

13493 macros with AU_DEFINE.

13516 the 2003-05-22 change, which removed the older years from the list.
13517 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

13525 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of

13528 egrep and fgrep respectively if $GREP -E/-F don't work.
13529 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
13530 _AC_PROG_GREP, and AC_PROG_SED.
13531 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
13532 longest input length accepted by a command.

13561 2004-01-26 Paul Eggert <eggert@twinsun.com>
13563 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
13564 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
13565 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
13566 not <inttypes.h>. Problem reported by Tim Mooney in
13567 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
13568 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
13571 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
13572 otherwise "make check" fails because it forbids cmp (I guess
13573 because cmp treats files as binary on DOS-like systems).
13575 * tests/mktests.sh: Update copyright date to 2004, since some tests
13576 have changed in 2004.
13578 2004-01-23 Gary V. Vaughan <gary@gnu.org>
13580 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
13581 non-truncating sed or gsed program in PATH.
13582 * tests/acprograms.at: Add it.

13586 2004-01-15 Paul Eggert <eggert@twinsun.com>
13588 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
13589 -std1 disables some useful extensions on Tru64. Problem reported
13590 by N. Lichtmaier in

13595 * doc/autoconf.texi (Programming in M4sh): Document that
13596 AS_MKDIR_P succeeds if the destination is a symbolic link
13597 to an existing directory.
13598 (Limitations of Usual Tools): Note that mkdir -p might not
13599 succeed on symlinks to directories.
13601 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
13603 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
13604 * bin/autoheader.in: Grammar fix in message.
13605 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
13606 Test for dir before calling mkdir -p. (trivial changes)
13608 2004-01-13 Eric Blake <ebb9@byu.net>

13613 2004-01-10 Jim Meyering <jim@meyering.net>

13617 2004-01-09 Paul Eggert <eggert@twinsun.com>
13619 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
13620 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
13621 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
13622 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
13623 AC_COMPILE_IFELSE, since we now assume our caller invokes
13624 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
13625 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
13626 of AC_RUN_IFELSE; this avoids the warning mentioned above.
13627 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
13629 2004-01-07 Paul Eggert <eggert@twinsun.com>
13631 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
13632 `"'...'"`, as it's confusing (and I suspect it may not work on
13633 some platforms). The code was incorrect anyway, as it assumed
13634 that \$ evaluated to itself in that context. Reported by
13635 Alexandre Duret-Lutz.
13637 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
13639 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
13640 and _LT_AC_TAGCONFIG.
13642 2004-01-06 Paul Eggert <eggert@twinsun.com>
13644 * doc/autoconf.texi (One Macro Call): Fix an incorrect

13665 2004-01-04 Paul Eggert <eggert@twinsun.com>
13667 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
13668 Use "rm -f" to remove conftest.sed, not plain "rm".
13669 Bug reported by David Relson in
13670 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
13672 * Makefile.am (autom4te-update):
13673 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

13687 2004-01-03 Paul Eggert <eggert@twinsun.com>
13689 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
13690 -c -o might not work. From a suggestion by Kevin Ryde.
13691 (C Compiler, Generating Sources, Limitations
13692 of Usual Tools, Limitations of Make, Making testsuite Scripts):

13995 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

14020 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
14021 cache variable instead of $G77 to decide whether to include -O2,

14032 arguments so that it can be used with syntax identical to

14034 remove/deprecate the DIALECT optional argument in the future if it
14035 proves troublesome.
14036 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for

14108 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
14109 directory for AC_CONFIG_COMMANDS' first argument exists.
14110 This makes valid the invocation of _AC_SRCPATH that follows.
14111 Reported by Eric Sunshine.

14135 The test suite are sometimes assigning timings incorrectly.
14136 Reported by Henk Krus.
14137 Diagnosed by Nicolas Joly.
14139 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
14141 Instead of making AT_help a sequence of assignments to grow

14143 $at_help_all, and make a single assignment in...
14145 (at_times_skip): Flip the meaning and rename as...
14146 (at_times_p): this.

14157 (ifnames): chmod -w.

14159 executables, not bin/ executables! Otherwise all the magic needed
14160 to find non installed files is turned off. This caused a failure
14161 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
14162 as found in its environment (sent by tests/autoreconf): pointing
14163 to bin/autom4te that could not find its files.
14164 * tests/mktests.sh: Force the replacement of generated files, for
14165 the sake of "mv" program that are interactive when overwriting a

14267 new macros AC_FC_SRCEXT to set the source extension, and
14268 AC_FC_FREEFORM to accept free-form source files.

14394 2003-08-21 Akim Demaille <akim@epita.fr>
14396 First stab at preserving warnings between calls to autom4te,
14397 including when the cache is used.
14399 There are still several issues: (i) there are too many runs of m4
14400 (one for include, one for warnings, and some more), (ii) warnings
14401 spreading on several lines are not handled gracefully, (iii) the
14402 code meant to have the call stack display for errors does not work
14403 (its handling should move from m4 to autom4te).
14405 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
14407 (@preselect): Add m4_warn.
14408 ($exit_status): Remove, use $exit_code.
14409 ($help): Use Autom4te::ChannelDefs::usage.
14410 (&handle_m4): No longer define the m4_warnings.
14411 At each run, extract and report the warnings.
14412 Always cache the result, including if the exit status is on
14413 failure, since if nothing changes, we should result in the same
14414 failure, hence we can use the cache.
14415 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
14416 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
14418 (m4_warn): Redefine as a do-nothing: it is its invocation that
14419 matters, as warnings are now reported via traces.
14420 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
14421 the contents of m4_warn: make it _call_ m4_warn, so that tracing
14422 the latter reveals calls to the former.
14426 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
14428 2003-08-21 Akim Demaille <akim@epita.fr>

14448 (&catfile): Remove.
14449 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
14450 * bin/autoscan.in: Adjust.
14452 2003-08-20 Akim Demaille <akim@epita.fr>
14454 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
14455 Reported by Alexandre Duret-Lutz.
14457 2003-08-20 Akim Demaille <akim@epita.fr>
14459 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
14460 * bin/autom4te: Adjust.
14461 In particular, be Autoconf tools are really silent when properly
14462 working, bind the verbosity of the 'note' channel to $verbose.
14463 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
14464 (&xsystem, &contents): Remove, since they are exported by...
14465 * lib/Autom4te/FileUtils.pm: this.

14468 * lib/Autom4te/FileUtils.pm: here.

14587 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,

14591 Don't mix the detailed output of failed test with the summary of

14674 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
14675 (handle_exec_errors): New function. Work around $! being
14676 altered by WEXITSTATUS.
14677 (xqx, xsystem): Use handle_exec_errors.
14679 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
14681 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
14682 Do not call `_exit()', simply modify `$?'.
14683 (xsystem): Reset $! before running system, and check it afterward.
14684 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
14685 63 for version mismatches.
14687 2003-05-23 Akim Demaille <akim@epita.fr>
14689 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
14690 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
14691 the middle of a line).
14692 * lib/m4sugar/m4sugar.m4: Likewise.
14693 Remove useless spaces in comments.
14695 2003-05-23 Akim Demaille <akim@epita.fr>
14697 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
14698 exit 63, so that we (or Automake's "missing") can tell the
14699 difference with a plain failure.
14700 * doc/autoconf.texi (Notices): Adjust.
14702 2003-05-23 Akim Demaille <akim@epita.fr>

14709 Paul Eggert <eggert@twinsun.com>
14711 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
14712 Remove `#include <stdlib.h>' from the list; we should never
14713 make confdefs.h include <stdlib.h> or <cstdlib>, because the
14714 resulting namespace pollution would cause other tests to fail.
14715 Configure scripts run with some older versions of g++ and HP's
14716 aCC would fail due to such an #include. Problems reported by
14717 Matthew Mueller in <http://bugs.debian.org/120704> and by
14719 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
14720 In the test, use the test declaration before including <stdlib.h>,
14721 as that's closer to how it'll be used.
14723 2003-05-23 Akim Demaille <akim@epita.fr>
14725 * doc/autoconf.texi (Header Portability): ucred.h.
14728 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
14730 Overhaul Autotest's logging: generate separate log files
14731 in testsuite.dir/NNN/testsuite.log, and append them to
14732 testsuite.log instead of re-running the test verbosely.
14734 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
14735 file descriptor, write 0 to at_status_file instead of setting
14736 at_status=0, initialize some new variables (at_status_file,
14737 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
14738 to rerun the tests, instead append the at_group_log to the
14739 at_suite_log when a test fails.
14740 (AT_SETUP): pipe the test case's output into at_tee_pipe,
14741 with the AS_MESSAGE_LOG_FD redirected to stdout.
14742 (AT_CLEANUP): save the output status in $at_status_file
14743 and restore it, redirect the AS_MESSAGE_LOG_FD back to
14744 its original place.
14745 (AT_CHECK): since tests are run with a redirected stdout,
14746 and used to be re-run in verbose mode, turn some $at_verbose
14747 into echo, and don't redirect the output of testing stdout
14750 * lib/autotest/autoconf.texi (testsuite Scripts): Update
14751 the name of the debugging directory and information about
14754 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

14871 2003-05-06 Akim Demaille <akim@epita.fr>
14873 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
14874 longer updates aclocal.m4 if useless, (ii) if a file m4_included
14875 by aclocal.m4 is changed it might require the importing of another
14876 m4 extension file, i.e., aclocal must be run.
14878 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
14879 (&parse_args): Use --force with aclocal if required and supported.

14889 open during the whole autom4te run.
14890 ($icache_file): New.
14891 (&freeze): Lock the $icache_file.
14893 2003-04-29 Derek Price <derek@ximbiot.com>
14895 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
14896 seperator with m4_append_uniq(). It doesn't work.
14897 (AT_CLEANUP): Add `;' to end of at_help_all.
14898 (AT_INIT): Allow --keywords to be specified more than once. When
14899 grepping $at_help_all for keywords, use the field and keyword
14900 seperators to ensure a complete keyword match. Alter at_prev handling
14901 to support the new --keywords behavior.
14903 2003-04-27 Karl Berry <karl@freefriends.org>
14905 * doc/autoconf.texi: Make the dir entries in the autoconf manual
14906 align better with others. I also made some of the individual
14907 entries on one line, for brevity and to make it easier for me to
14908 sort my dir-example file in the Texinfo distribution :).

14974 reading the section "Present But Cannot Be Compiled" when the
14975 header causes problems.
14977 2003-03-28 Akim Demaille <akim@epita.fr>
14979 * tests/torture.at (Configuring subdirectories): Require aclocal
14980 1.4, otherwise the test fails, as it does support configure.ac.

15106 is not portable inside Makefile.
15108 2003-02-20 Akim Demaille <akim@epita.fr>
15110 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
15111 compiler says yeah, but preproc says nope, compiler is right.
15112 Conversely, prompt the reader to send a bug report to the
15113 maintainers of the package, not of Autoconf.
15115 2003-02-20 Klee Dienes <kdienes@apple.com>

15128 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
15129 innocuous variant befor including <limits.h> or <assert.h>. This
15130 works around a bug reported by Albert Chin: HP-UX 11i
15131 (and earlier versions) have a <limits.h> that declares
15132 gettimeofday and many other functions.
15134 2002-12-03 Paul Eggert <eggert@twinsun.com>

15148 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
15149 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
15150 defined, to support freestanding compilers. This should fix the
15151 bug reported by Momchil Velkov in

15186 Update from masters.
15188 2002-11-14 Akim Demaille <akim@epita.fr>
15190 * Makefile.maint: Sync with Bison, i.e.:
15191 (po-check): Scan .l and .y files instead of the
15192 .c and the .h files that they generate. This fixes the bug
15193 reported by Tim Van Holder in:
15194 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
15195 Look for N_ as well as for _. Try to avoid matching #define for

15211 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
15212 than assigning in main, to avoid HP cc +O3 optimizing it away.

15216 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
15217 option. Process --recheck after parsing all options. Pass -q
15218 option to configure on --recheck.

15254 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
15256 We _have_ to stop using the old compatibility scheme that tried to
15257 avoid useless backslashes because Libtool 1.4.3 contains a
15258 AC_DEFINE([error_t], [int],
15259 [Define to a type to use for \`error_t' if it is not
15260 otherwise available.])
15261 We _have_ to quote the single quote and backslashes with \. The
15262 old compatibility scheme saw that ` was backslashed, and therefore
15263 did not quote the single quote. Hence before this patch, Autoconf
15264 was not compatible with Libtool.

15309 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
15310 Make variable, not a shell variable.
15311 Suggested by Bruno Haible.

15338 Problem reported by Bruno Haible.

15342 * doc/autoconf.texi (Header Templates): Put also in words what the

15658 to frozen files in @ARGV, as @ARGV must remain being a list of
15659 files. Rather, at M4 call sites, use this...
15660 (&files_to_options): New function.
15661 (&freeze): Use &error.
15662 (&up_to_date): If a file that was included according to the cache
15663 is no longer there, then the output is out dated.
15664 (&main): Don't even check whether a file is up to date is anyway
15666 * tests/tools.at (autom4te cache): New.
15668 2002-10-16 Akim Demaille <akim@epita.fr>
15670 * bin/autoconf.as: Kill dead options.
15671 * bin/autoupdate.in (&parse_args): Kill old options.
15672 * bin/autoreconf.in (&parse_args): Remove dead options.
15674 (&autoreconf): Report the directories we enter *and leave*, so
15675 that error messages can be easily located, and use GNU Make
15676 format, so that Emacs' compile mode understands us.
15677 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
15678 if some file was changed instead of `print'.
15679 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
15680 (&parse_args): Remove the dead options.
15681 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
15682 autoheader's quiet mode.
15683 (AT_CHECK_AUTOUPDATE): Likewise.
15684 * tests/tools.at (autoupdate): Adjust.
15685 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
15687 2002-10-11 Akim Demaille <akim@epita.fr>
15689 No longer use CPP to check for the existing of headers: use CC to
15690 check for compilability.
15692 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
15693 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
15694 (_AC_CHECK_HEADER_NEW): Rename as...
15695 (AC_CHECK_HEADER): this.
15697 * lib/autotest/general.m4 (AT_INIT): Include the failed test
15698 numbers in the Subject suggestion.
15700 2002-10-11 Akim Demaille <akim@epita.fr>
15702 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
15703 Suggest using AC_CHECK_DECLS instead.
15705 2002-10-11 Akim Demaille <akim@epita.fr>
15707 * tests/torture.at (AC_ARG_VAR): Have configure report the value
15710 2002-10-11 Akim Demaille <akim@epita.fr>
15712 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
15713 file name to enable parallel executions.
15714 From Sam Varshavchik.
15716 2002-10-08 Akim Demaille <akim@epita.fr>
15718 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
15719 aclocal invocation, as Gettext macros might not be visible to
15721 Instead of blindly running autopoint, scan configure.ac (not the
15722 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
15723 Reported by Paul D. Smith.
15725 2002-10-08 Paul Eggert <eggert@twinsun.com>
15727 Work around problems found when POSIXLY_CORRECT=1 is set.
15728 None of this seems to have anything to do with POSIX, really,
15729 but it's how Perl getopt works.
15730 * bin/autom4te.in (parse_args): Configure GetOpt with
15732 * doc/autoconf.texi (Invoking autom4te):
15733 --warning -> --warnings.
15734 * lib/autom4te.in: --warning -> --warnings.
15736 2002-09-28 Akim Demaille <akim@epita.fr>
15738 * doc/autoconf.texi (autom4te.cache): New section.

15746 2002-09-28 Akim Demaille <akim@epita.fr>

15749 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
15750 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
15751 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
15753 2002-09-28 Akim Demaille <akim@epita.fr>
15755 * tests/torture.at (Configuring subdirectories): Be robust to
15756 users who use config.site to require for a cache: in this case,
15757 the two last configure runs, using two different sets of
15758 arguments, trigger a legitimate error.
15760 2002-09-28 Akim Demaille <akim@epita.fr>
15762 * tests/m4sh.at (Functions Support, Functions and return Support):
15765 2002-09-28 Akim Demaille <akim@epita.fr>
15767 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
15768 autoheader are Perl programs.

15778 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
15779 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
15780 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

15793 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
15794 (.m4.m4f): Don't pass --prepend-include, since that's done by
15795 tests/autom4te itself.
15796 * lib/autoscan/Makefile.am: Include freeze.mk.
15797 (autoscan.list): New target --this file is no longer a source.
15798 (autoscan.pre): New file.
15800 2002-09-28 Akim Demaille <akim@epita.fr>
15802 * bin/autoscan.in (@kinds): Make them singular.
15804 (&init_tables): When --debug, report the list of rules to ease
15805 tracking changes in autoscan.list.
15806 * lib/autoscan/autoscan.list (function): Strip comments, sort.
15808 2002-09-28 Akim Demaille <akim@epita.fr>
15810 * lib/autoscan/functions, lib/autoscan/headers,

15814 * bin/autoscan.in (&init_tables): Adjust.
15816 2002-09-28 Akim Demaille <akim@epita.fr>
15818 * lib/autoscan/functions, lib/autoscan/headers,
15819 * lib/autoscan/identifiers, lib/autoscan/makevars,
15820 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
15821 `functions' line is now prefixed with `function:'.
15822 * bin/autoscan.in (&init_tables): Adjust.
15824 2002-09-28 Akim Demaille <akim@epita.fr>
15826 From now on, autoscan files must always map a macro name to a
15827 word: there is no `default' macro for autoscan.
15829 * bin/autoscan.in (&init_tables): Reject entries with no macro at
15831 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
15834 2002-09-28 Akim Demaille <akim@epita.fr>
15836 * bin/autoscan.in (%c_keywords): Remove.
15837 (&used): Keep only track of the words we might be interested in.
15838 (&output_kind): It is no longer needed to look for non active
15841 2002-09-27 Akim Demaille <akim@epita.fr>
15843 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

15854 the tmpdir must be created.
15855 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
15856 dir be in the build tree, instead of $TMPDIR.
15858 2002-09-27 Akim Demaille <akim@epita.fr>
15860 * bin/autoscan.in: Improve the comments.
15861 (&parse_args): Drop obsolete undocumented options.

15869 Reported by Ralf Corsepius.
15870 * doc/autoconf.texi (autoreconf Invocation): Likewise.
15872 2002-09-26 Akim Demaille <akim@epita.fr>
15874 Single suffix rules and seperated dependencies are not portable.
15876 * doc/autoconf.texi (Installation Directory Variables): Update.
15877 (Limitations of Make): Some about `Single Suffix Rules and
15878 Separated Dependencies'.
15879 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
15880 (ifnames, autoscan, autom4te): Un-factor into several rules.
15882 2002-09-25 Paul Eggert <eggert@twinsun.com>
15884 * BUGS (Interoperability bugs): New section. Mention libtool
15885 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
15887 2002-09-24 Paul Eggert <eggert@twinsun.com>
15889 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
15890 make handles suffix-rules differently from GNU make.
15892 * bin/Makefile.am (SUFFIXES, .in): Remove.
15893 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
15894 Move the body of the old .in rule here.
15896 2002-09-16 Akim Demaille <akim@epita.fr>
15898 i960 compilers create `b.out' files by default.
15899 Reported by Ralf Corsepius.
15901 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
15902 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
15904 2002-09-13 Paul Eggert <eggert@twinsun.com>
15906 * doc/autoconf.texi (Particular Headers): Remove obsolete
15907 reference to `struct timezone' in the description of
15910 2002-09-13 Akim Demaille <akim@epita.fr>
15914 * config/config.sub, config/config.guess: Update.
15915 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
15916 * Makefile.am: Adjust.
15918 2002-09-13 Akim Demaille <akim@epita.fr>
15920 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
15921 reading config.log when the compiler is rejected.
15922 Suggested by Guido Draheim.
15924 2002-09-13 Akim Demaille <akim@epita.fr>
15926 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
15927 (chdir_init) might hang when stat'ing mounted directories.
15928 Reported by Vance Shipley.
15930 2002-09-12 Akim Demaille <akim@epita.fr>
15932 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
15935 2002-09-12 Akim Demaille <akim@epita.fr>
15937 * doc/autoconf.texi (Defining Symbols): Present two different
15938 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
15939 difference between 1 argument calls, and 2-3 argument calls.
15941 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
15943 * doc/autoconf.texi: Review grammar and punctuation.
15945 2002-09-11 Paul Eggert <eggert@twinsun.com>
15947 * doc/autoconf.texi: Fix minor formatting, spelling, and
15949 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
15950 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
15953 2002-09-11 Akim Demaille <akim@epita.fr>
15955 * doc/autoconf.texi (Questions): Rename as...
15957 (Defining Directories): New.
15959 2002-09-09 Akim Demaille <akim@epita.fr>
15961 * doc/autoconf.texi (Making testsuite Scripts): Update.
15962 Suggested by Nishio Futoshi.
15964 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
15966 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
15967 plain `@' is wanted.
15969 2002-09-09 Akim Demaille <akim@epita.fr>
15971 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
15972 `duplicates', since the algorithm was too naive and could keep
15973 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
15974 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
15975 Reported by Ralf Corsepius.
15976 * tests/torture.at (Configuring subdirectories): Exercise these
15979 2002-09-09 Akim Demaille <akim@epita.fr>
15981 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
15982 looking for a replacement file.
15983 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
15984 directory is relative.
15985 * doc/autoconf.texi (Generic Functions): Clarify the replacement
15986 directory definition.
15987 Reported by Andreas Schwab and Jim Meyering.
15989 2002-09-06 Akim Demaille <akim@epita.fr>
15991 * doc/autoconf.texi (Setting Output Variables): Clarify what
15992 precious variables are.
15993 Suggested by Pontus Skoeld.
15995 2002-09-05 Akim Demaille <akim@epita.fr>
15997 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
15998 (ifnames, autoscan, autom4te): Since we don't only depend on
15999 configure.ac variables (such as VERSION etc.), but also on prefix
16000 and so forth, depend on Makefile, not configure.ac.
16001 Reported by Alexandre Duret-Lutz.
16002 * doc/autoconf.texi (Installation Directory Variables): Adjust.
16004 2002-09-05 Kevin Ryde <user42@zip.com.au>
16006 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
16007 doesn't seem to be confined to ia64, just say "some versions".
16009 2002-09-04 Akim Demaille <akim@epita.fr>
16011 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
16013 * Makefile.am (maintainer-clean-local): Remove.
16014 (MAINTAINERCLEANFILES): Remove COPYING.
16016 2002-09-03 Paul Eggert <eggert@twinsun.com>
16018 * doc/autoconf.texi (Configuration Commands): Remove obsolete
16019 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
16022 2002-09-03 Akim Demaille <akim@epita.fr>
16024 * configure.ac: Bump to 2.53d.
16025 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
16026 as of today, on Automake's team suggestion.
16028 2002-09-03 Akim Demaille <akim@epita.fr>
16032 2002-09-02 Akim Demaille <akim@epita.fr>
16034 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
16036 * configure.ac: Disable SITE_MACRO_DIR.
16038 2002-09-02 Jim Meyering <meyering@lucent.com>
16040 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
16041 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
16042 Also, tweak grammar: s/make sure to/be sure to/.
16044 2002-09-02 Paul Eggert <eggert@twinsun.com>
16046 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
16047 directory names are generally preferable to physical names.
16049 2002-09-02 Akim Demaille <akim@epita.fr>
16051 * lib/Autom4te/General.pm (&update_file): s/die/error/.
16052 Reported by Raja R. Harinath.
16053 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
16054 * bin/autoupdate.in: Use error instead of die.
16056 2002-09-01 Paul Eggert <eggert@twinsun.com>
16058 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
16059 ordinary shell concatenation rather than echo+tr+sed command that
16060 runs afoul of a long-line-related sed bug in Solaris 8.
16062 * bin/autoheader.in (parse_args): --warning -> --warnings.
16064 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
16065 stdout, as traditional "ls" does.
16066 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
16067 _AC_COMPILER_EXEEXT_O): Likewise.
16068 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
16070 * bin/autoconf.as: Add --prepend-include option. This patch was
16071 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
16072 but bin/autoconf.in is generated automatically from bin/autoconf.as.
16074 * bin/autoconf.in, configure: Regenerate.
16076 * doc/autoconf.texi (Special Shell Variables): Mention
16077 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
16079 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
16080 MAILPATH and set PS1, PS2, PS4 to default values, to work
16081 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
16082 For LC_ALL etc, first try to set to "C" as POSIX requires and as
16083 the Autoconf documentation specifies; fall back to "unset" only if
16084 this fails. Use a shell for-loop for this rather than an m4 loop,
16085 to shorten the output script.
16087 2002-08-30 Paul Eggert <eggert@twinsun.com>
16089 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
16090 1003.1-2001's requirements for CDPATH. Give a simpler workaround
16091 for the CDPATH problem. Document PWD.
16092 (Limitations of Builtins): Document the problem that "cd $foo" and
16093 "ls $foo" may refer to different directories in shells conforming
16094 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
16095 example, since the old example is now out of date.
16097 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
16098 FOO" and "ls FOO" talk about different directories; this catches
16099 problems when POSIX 1003.1-2001 "cd" fails due to symlink
16102 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
16103 of rolling our own unset.
16104 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
16105 in practice we needn't worry about CDPATH if unset doesn't work.
16107 * Makefile.in, aclocal.m4, bin/Makefile.in,
16108 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
16109 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,

16111 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
16112 tests/Makefile.in: Regenerate with Automake 1.6.3.
16114 * config/config.guess, config/config.sub, config/mkinstalldirs:
16117 * configure: Regenerate with self.
16119 2002-08-30 Kevin Ryde <user42@zip.com.au>
16121 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
16124 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
16126 * bin/autom4te.in (Request::load): Correctly test for "do" read
16129 2002-08-29 Akim Demaille <akim@epita.fr>
16131 * lib/Autom4te/General.pm (&xqx): New.
16132 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
16133 hand, which is not portable.
16135 * bin/autom4te.in: Use them.
16136 Use &error instead of die.
16137 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
16140 2002-08-17 Paul Eggert <eggert@twinsun.com>
16142 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
16143 default list of compilers to try, since it was long ago superseded

16316 2002-06-27 Paul Eggert <eggert@twinsun.com>
16318 * config/install-sh: Quote $src. Prefer || to test's -o option,
16319 as per "Limitations of Builtins".

16460 This improves on an earlier suggestion by H. Peter Anvin.
16462 2002-05-16 Paul Eggert <eggert@twinsun.com>
16464 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
16465 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
16466 Both macros now accept an optional source-dir arg.
16467 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
16469 * NEWS: Document this.
16470 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
16472 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
16473 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
16474 not for GNU extensions; this undoes part of the 2000-11-03 change,
16475 reverting to 2.13-compatible behavior.
16476 Add new optional argument DIR.
16477 (AC_FUNC_FNMATCH_GNU): New macro.

16483 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
16484 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
16485 and it causes a 'test' syntax error if it fails.
16486 Bug reported by Stephen Gildea.
16488 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
16489 If prototypes are supported, use them to check this at compile-time,
16490 instead of trying to check it at run-time. If we must do a run-time
16491 check, assume that setvbuf is standard when cross-compiling, as
16492 nonstandard setvbuf occurs only on ancient and unlikely hosts.
16493 Bug reported by Paul D. Smith.
16495 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
16496 argument specifying location of getloadavg.c. This removes a
16497 FIXME. This idea was taken from Jim Meyering's implementation in
16499 * doc/autoconf.texi (Particular Functions): Document this.
16500 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
16501 that's what the code does; this fixes a bug reported by

16507 autopoint instead of gettextize.
16508 ($uses_alocal): Rename as...
16509 ($uses_aclocal): this.
16510 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16511 Suggested by Bruno Haible.

16517 2002-04-29 Paul Eggert <eggert@twinsun.com>
16519 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
16520 files to be 1 second older; just set them to be the same time.
16521 Also, sleep 1 second after the first aclocal, to work around
16522 problems with sub-second time stamps on the input files.
16524 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
16526 * doc/autoconf.texi: Mention "set -e -x" lossage
16527 under node "Limitations of Builtins".

16533 From Christian Cornelssen.
16535 2002-04-29 Akim Demaille <akim@epita.fr>
16537 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
16538 of lack of $LINENO support, then the test will compare the $LINENO
16539 in testsuite vs. the lineno in the test file. This is wrong, of
16541 Be sure to protect it.
16542 Reported by Patrick Welche.
16544 2002-04-25 Akim Demaille <akim@epita.fr>
16546 * doc/autoconf.texi (Obsolete Macros): Typo.
16547 Reported by Vladimir Volovich.
16549 2002-04-25 Akim Demaille <akim@epita.fr>
16551 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
16552 than some of the input files, hence, on the second run of aclocal,
16553 if some of its input are younger, make them older.
16554 Suggested by Paul Eggert.
16556 2002-04-25 Akim Demaille <akim@epita.fr>
16558 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

16567 (_AC_INIT_PREPARE): Use them to log them.
16568 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
16569 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
16570 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
16571 _AC_SUBST_FILES and _AC_SUBST_VARS.
16572 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
16574 2002-04-24 Akim Demaille <akim@epita.fr>
16576 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
16577 autoheader, so that automake does not complain about a missing

16580 2002-04-23 Akim Demaille <akim@epita.fr>

16631 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
16632 Minor spelling and grammar fixes.
16634 * doc/autoconf.texi: Follow the outline suggested in the GNU
16635 Sample Texts sections of the Texinfo 4.2 manual. Most
16636 importantly, this makes sure that the copyright notices appear in
16637 all output formats. You probably need Texinfo 4.2 to generate

16666 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
16667 from aclocal.m4 too.
16669 2002-04-12 Akim Demaille <akim@epita.fr>
16671 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
16673 2002-04-10 Akim Demaille <akim@epita.fr>
16675 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
16676 workaround for ${1+"$@"}.
16677 * doc/autoconf.texi (Shell Substitutions): Explain it.
16678 From Oliver Kiddle and Peter Stephenson.
16680 Have M4sh perform minimal shell sanitizing.
16682 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
16684 (_AS_PREPARE): this new macro.

16689 Adjust Autoconf and Autotest.
16691 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
16692 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
16693 * lib/autotest/general.m4 (AT_INIT): Likewise.
16694 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
16695 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
16698 Use this M4sh to generate Autoconf's shell scripts.
16700 * tests/wrapsh.as: New, precursor of wrapsh.in.
16701 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
16702 on Autotest and M4sh.
16703 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
16704 (wrapsh.in): New target.
16705 * bin/autoconf.as: New, precursor of autoconf.in.
16706 (autoconf.in): New target.
16708 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

16711 with indented comments in rules.

16726 directories when descending in a SUBDIRS.
16727 Reported by Ezra Peisach.
16729 2002-04-04 Andreas Schwab <schwab@suse.de>
16731 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
16732 contains no literal separators.
16734 2002-04-03 Akim Demaille <akim@epita.fr>
16736 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
16737 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
16738 Use dnl, not the KILL diversion.
16740 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
16741 (AC_CONFIG_LINKS): here.
16743 Don't use the KILL diversion, as it kills spurious output, which
16744 results in failures being hidden.
16745 Use m4_defn where appropriate.
16746 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
16747 after the second argument.
16749 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
16750 syntax, as it is provided by M4sugar.

16792 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
16793 to avoid versions of HP C which don't allow that.
16795 2002-03-27 Paul Eggert <eggert@twinsun.com>
16797 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
16798 (AS_SHELL_SANITIZE): Invoke it.
16799 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

16805 2002-03-26 Akim Demaille <akim@epita.fr>

16809 2002-03-25 Paul Eggert <eggert@twinsun.com>
16811 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
16812 as POSIX requires, as it doesn't work with Zsh.
16813 * doc/autoconf.texi (Assignments): Document the problem.
16815 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
16817 * doc/autoconf.texi (Limitations of Make): Mention more issue
16818 about VPATH, overriding of macros in sub-makes, and handling of
16821 2002-03-21 Paul Eggert <eggert@twinsun.com>
16823 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
16824 problem with here-document buffer boundaries.
16826 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
16827 when reinvoking the shell, to work around problems with installers
16828 who put strange things like "cd" commands in their environments.
16830 2002-03-19 Akim Demaille <akim@epita.fr>
16832 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

16837 * bin/autoscan.in (scan_file): Specify the location in `&used'
16841 2002-03-19 Akim Demaille <akim@epita.fr>

16844 From Nishio Futoshi.
16846 2002-03-19 Akim Demaille <akim@epita.fr>
16848 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

16852 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
16853 (Limitations of Usual Tools): Add mkdir section.
16855 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
16856 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
16857 back on AS_DIRNAME to compute prefixes otherwise; this is
16858 roughly what mkinstalldirs does. That way, we need not have
16859 our own filename disassembler. The old disassembler did not
16860 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
16862 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
16863 Create at_test_all by a series of assignments,
16864 not by a single assignment of a long string. The latter causes ksh
16865 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
16866 presumably because of a buffer overrun.
16868 2002-03-14 Paul Eggert <eggert@twinsun.com>
16870 * lib/autotest/general.m4 (at_times_skip):
16871 Renamed from at_times. Now a boolean.
16872 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
16873 says 'times: not found'.
16875 2002-03-14 Akim Demaille <akim@epita.fr>
16877 * bin/autoreconf.in (&study_gettextize): New.
16878 (&autoreconf): Handle newest gettextize.

16889 Add information about stdint.h and inttypes.h from Paul Eggert.
16891 2002-03-13 Akim Demaille <akim@epita.fr>

16897 2002-03-12 Akim Demaille <akim@epita.fr>

16902 2002-03-11 Andreas Schwab <schwab@suse.de>
16904 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
16905 does not do it if --with-lispdir is given.
16907 2002-03-08 Akim Demaille <akim@epita.fr>
16911 2002-03-08 Akim Demaille <akim@epita.fr>

16914 subdirectory should exist.
16916 2002-03-08 Akim Demaille <akim@epita.fr>
16918 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
16920 2002-03-08 Akim Demaille <akim@epita.fr>
16922 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
16923 aliases the actual variables, and modifications of the former
16926 2002-03-08 Akim Demaille <akim@epita.fr>
16928 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
16929 because of C-c: have m4 output in tmp files, then mv them.
16931 2002-03-08 Akim Demaille <akim@epita.fr>
16933 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

16950 2002-03-04 Akim Demaille <akim@epita.fr>
16952 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
16953 * lib/autoconf/general.m4 (AC_INIT): More informative error
16954 message for LIBOBJ.
16956 2002-03-04 Akim Demaille <akim@epita.fr>

16961 2002-03-04 Akim Demaille <akim@epita.fr>
16963 * doc/autoconf.texi (Transforming Names): Equality between target
16964 and host is irrelevant.
16965 (Specifying Names, Canonicalizing): Remove all references to the
16966 backward compatibility hooks. Rather, collect them all into...
16967 (Hosts and Cross-Compilation): this new section.
16968 * doc/install.texi (System Type): Ditto.
16969 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
16970 that `--host' implies cross-compilation.

16974 * doc/autoconf.texi (Evaluation Macros): New.
16975 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
16977 (_m4_foreach): Define the variant with immediate evaluation so
16978 that it contains exactly the items, not an expression which
16979 evaluation is the current item.
16980 (m4_re_string, m4_re_word): Don't over quote them.
16982 2002-03-04 Akim Demaille <akim@epita.fr>
16984 Instead of having stacking `shift's evaluated at the end, let
16985 `foreach' loops immediately evaluate them.
16987 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
16988 $*. This is the n-th time I change my mind, but hopefully this is
16991 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
16993 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
16994 it was only a hack for m4_text_wrap.
16995 (m4_car2): Remove, replaced by...
16997 (_m4_foreach): Adjust.
16998 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
16999 m4_bpatsubst for clarification.

17051 AC_PREFIX_PROGRAM fails with dashed program names
17053 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
17054 variable when looking for the prefix program.
17055 Now it also works for shell variables.

17132 2002-01-30 Akim Demaille <akim@epita.fr>
17134 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
17135 for plain code, the other for cross-compilation code. The latter
17136 is now run with GCC only.
17137 * doc/autoconf.texi (Compilers and Preprocessors): New.

17144 change AC_INIT default values.
17146 2002-01-29 Akim Demaille <akim@epita.fr>
17148 * tests/torture.at (Configuring subdirectories): Use configure.in,
17149 so that aclocal 1.4 works.
17150 Reported by Alexandre Duret-Lutz and Larry Schmitt.
17152 2002-01-28 Akim Demaille <akim@epita.fr>
17154 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
17157 2002-01-28 Akim Demaille <akim@epita.fr>
17159 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
17160 AUTOTEST_PATH *after* it was set.
17161 Don't put `.' in the PATH: the user should be precise and `./' if
17162 needed. In addition, given that the test suite does some `cd', if
17163 `.' is in the path, the `tested programs' sections will report
17164 programs found in the test suite's directory, while during the
17165 tests (performed in their own directory), these programs are no
17166 longer visible. In other words, the results is confusing and
17168 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

17181 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
17182 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
17183 Bourne. Use /bin/sh.
17184 From Andreas Buening.
17186 2002-01-24 Akim Demaille <akim@epita.fr>
17188 * config/config.guess, config/config.sub, config/texinfo.tex:

17212 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
17213 message on invalid options.
17214 * bin/autom4te.in (parse_args): Don't use
17215 Autoconf::General::getopt with non valid options.
17217 2002-01-17 Jim Meyering <meyering@lucent.com>
17219 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

17234 package.m4, since is really depends upon configure.ac, not
17236 * doc/autoconf.texi (testsuite Scripts): Adjust.
17237 * tests/Makefile.am (package.m4): New.
17238 EXTRA_DIST it since its a source.
17240 2002-01-06 Akim Demaille <akim@epita.fr>
17242 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
17243 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
17244 and PACKAGE_BUGREPORT from here...
17245 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
17247 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
17248 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
17249 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
17250 * tests/tools.at (autoheader): Adjust.
17251 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.

17272 2001-12-14 Akim Demaille <akim@epita.fr>
17274 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
17275 trailing files, don't apply `-rf' to files which might not be
17276 created by configure (core, core.*, and *.core), but just `rm -f'.
17277 Suggested by Jonathan Kamens.
17279 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
17281 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
17283 2001-12-14 Akim Demaille <akim@epita.fr>
17285 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
17287 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

17290 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
17291 abs_srcdir, top_srcpath to abs_top_srcdir.
17292 (_AC_OUTPUT_FILES): Adjust.
17293 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,

17303 2001-12-12 Kevin Ryde <user42@zip.com.au>
17305 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
17306 forbidden file descriptors table.
17308 2001-11-26 Akim Demaille <akim@epita.fr>
17310 * bin/autoscan.in (%c_keywords): Build it at top level.
17311 Map to 1 in order to simplify its uses.

17315 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
17316 Remove $filepath, useless.
17317 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
17318 variables, they are really part of the tokens.
17319 Split the input line on spaces and then look for tokens.
17320 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
17321 because of `lex$U.$(OBJEXT)'.
17322 (&scan_files): Use "@list" instead of join.
17323 * doc/Makefile.am (CLEANFILES): Add *.fns.

17328 Remove, replaced by...
17329 * tests/wrappl.in: Be common for all the Perl executables.
17330 In particular autoscan and autoheader want -I.
17331 * configure.ac: Adjust.
17332 * lib/autoscan/headers: errno.h is portable.
17334 2001-11-26 Akim Demaille <akim@epita.fr>
17336 * bin/autoscan.in (used): New.
17339 2001-11-26 Akim Demaille <akim@epita.fr>
17341 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
17343 (&scan_sh_file): Remove a duplicate pattern.
17344 (&check_configure_ac): Use long options.

17361 Test groups are now run two directories deeper.
17363 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
17364 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
17366 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
17367 top_srcdir, builddir and top_builddir.
17368 Use `at_*dir' relatively to the directory containing the
17369 suite, use `*dir' when relatively to the current group dir.
17371 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
17373 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
17374 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
17375 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
17378 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17380 * doc/autoconf.texi (Using System Type): Add an example of `case
17381 $host' usage so people quit using `case $target' everywhere.
17383 2001-11-22 Akim Demaille <akim@epita.fr>
17385 * doc/autoconf.texi (Installation Directory Variables): Englishoes
17386 spotted by Jim Meyering.
17388 2001-11-16 Paul Eggert <eggert@twinsun.com>
17390 This patch implements a `long double' suggestion by Oliver Kiddle.
17392 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
17393 static, to catch errors if the value isn't known at compile-time
17394 and the compiler supports dynamic arrays. Change its name from
17395 `_array_' to `test_array' to avoid potential name clashes.
17396 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
17397 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
17398 better than double. Catch a bug in GCC 2.95.2 x86.
17399 * doc/autoconf.texi (C Compiler): Document the above.
17402 2001-11-13 Akim Demaille <akim@epita.fr>
17404 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
17406 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
17408 2001-11-13 Akim Demaille <akim@epita.fr>
17410 * lib/autotest/general.m4 (AT_INIT): After having run the test
17411 group, go back to the initial directory, not to at_suite_dir.
17413 2001-11-13 Akim Demaille <akim@epita.fr>
17415 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
17416 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
17417 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
17419 (AT_CHECK_CONFIGURE): Use absolute paths.
17420 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
17421 The problem is still the old one: there is no means in M4 (that I
17422 know about) to create a defining macro, because there is no means
17423 to create `$1' etc., therefore, the defining macro ``swallows''
17424 all the arguments meant to the defined macro.
17426 2001-11-13 Akim Demaille <akim@epita.fr>
17428 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
17429 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
17431 * tests/aclocal.m4: Remove, as it is no longer used.
17433 2001-11-13 Akim Demaille <akim@epita.fr>
17435 * lib/autotest/general.m4: Change `tests?' into `groups?' in
17436 variable names when referring to a single test group, or to
17437 `suite' when referring to the whole test suite.
17438 `at_last_test' is removed: m4 compute at_format itself.
17439 (at_stdout, at_stder1, at_stderr): New variables.
17440 (AT_CHECK): Use them.
17442 2001-11-13 Akim Demaille <akim@epita.fr>
17444 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
17446 Create `testsuite.dir/003/run' instead of `testsuite.003'.
17447 Do it as soon as a test fails, don't wait till the end of the test
17449 Don't remove $as_me.[0-9]*, since these files no longer exist.
17451 2001-11-13 Akim Demaille <akim@epita.fr>
17453 * tests/tools.at: Use absolute paths, since we are no longer run
17456 2001-11-13 Akim Demaille <akim@epita.fr>
17458 Now that tests are running in their own private dir, there is no
17459 need to list the files to remove at the end of tests groups.
17461 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
17462 (AT_data_files, at_data_files): Remove.
17463 (AT_CLEANUP, AT_DATA): Simplify.
17465 Remove the group dir if !debug && !failed.
17466 * tests/atspecific.m4: Adjust.
17468 2001-11-13 Akim Demaille <akim@epita.fr>
17470 Start a new layout for Autotest: `testsuite' creates
17471 `testsuite.dir' in which the at-check-line etc. files are to be
17472 found, and `testsuite.dir/003' where the test group 3 is run.
17474 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
17475 at_check_line_file, at_format, at_test_normalized, at_group_dir
17477 Create the directories.
17478 Use absolute paths for at- files.
17479 (AT_CHECK): Adjust.
17481 2001-11-11 Michael Matz <matz@kde.org>
17483 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
17485 (m4_car): Properly quote arguments.
17487 2001-11-13 Akim Demaille <akim@epita.fr>
17489 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
17490 with stricter rules on LIBOBJS.
17492 2001-11-12 Paul Eggert <eggert@twinsun.com>
17494 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
17495 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
17498 2001-11-12 Akim Demaille <akim@epita.fr>
17500 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
17502 2001-11-12 Akim Demaille <akim@epita.fr>

17507 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
17508 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
17509 specify to what the macro should be defined (typically to 1).
17511 2001-11-12 Akim Demaille <akim@epita.fr>
17513 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
17516 2001-11-12 Akim Demaille <akim@epita.fr>
17518 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
17519 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
17520 definition used by Automake where LEX is +/- "${missing} lex" and
17521 `missing' itself contains variables.
17523 2001-11-12 Akim Demaille <akim@epita.fr>
17525 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
17526 Now that M4sh pushes BODY, the comments were output at the end of
17529 2001-11-08 Akim Demaille <akim@epita.fr>
17531 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
17532 that we can trace macros from aclocal.m4.
17533 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
17534 obsoleted, and redirect to the former anyway.
17535 Reported by Ralf Corsepius.
17537 2001-11-08 Akim Demaille <akim@epita.fr>
17539 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
17540 processed only if present.
17541 * tests/torture.at (Configuring subdirectories): Use autoreconf
17542 instead of successive calls to autoconf.
17543 Add a nonexistent subdirectory to exercise the patch above.
17544 Reported by Ralf Corsepius.
17546 2001-11-08 Kevin Ryde <user42@zip.com.au>
17548 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
17549 doesn't accept .S files.

17563 * lib/autom4te.in: Adjust.
17565 2001-11-05 Akim Demaille <akim@epita.fr>
17567 * tests/Makefile.am (testsuite): Rename this target as...
17568 ($(TESTSUITE)): this.
17571 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
17573 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
17574 the --prefix option, also remove it's argument.
17576 2001-11-05 Akim Demaille <akim@epita.fr>
17578 * doc/autoconf.texi (testsuite Invocation): Update.
17579 (Writing testsuite.at): Update.

17588 (&file_name_is_absolute): New, wrappers around routines from
17590 Use and export them.
17591 (&find_configure_ac): Optionally take a directory where to look at.
17592 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
17594 Default @ARGV to `.', not find_configure_ac.
17595 (&autoreconf): Argument is a directory.
17596 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
17597 * doc/autoconf.texi (autoreconf Invocation): Update.
17599 2001-11-03 Akim Demaille <akim@epita.fr>

17606 Don't look for aclocal flags if we already know aclocal is not
17608 Move aclocal.m4t only if it exists.
17609 Reported by Ezra Peisach.
17611 2001-11-03 Akim Demaille <akim@epita.fr>
17613 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
17614 passed on command line, defaulting to ./configure.ac if present.
17615 (&maybe_autoreconf, File::Find): Remove, unused.
17616 (&autoreconf): If autoconf is not used, don't try to trace.
17618 2001-11-02 Akim Demaille <akim@epita.fr>

17629 * config/lispdir.m4: Update from masters.
17630 * configure.ac: Bump to 2.52f.
17632 2001-11-02 Akim Demaille <akim@epita.fr>
17634 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
17635 Don't run aclocal when aclocal.m4 is not from aclocal.
17637 Don't run libtoolize and gettextize if --install is not given.
17639 2001-11-01 Paul Eggert <eggert@twinsun.com>
17641 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
17642 be invoked before _AS_LINENO_PREPARE.
17643 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
17644 than character ranges.
17646 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
17647 invoking AS_BASENAME. Set the locale variables to 'C' if
17648 possible, as POSIX requires this to get the traditional
17650 * doc/autoconf.texi (Special Shell Variables): Describe the above.
17652 2001-10-31 Paul Eggert <eggert@twinsun.com>
17654 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
17655 with {}, as that triggers a bug in Bash 2.05.
17657 (_AS_LINENO_PREPARE): Use Sed rather than
17658 Awk. Fix the sed prepass to work even if there are multiple
17659 instances of $LINENO on the same line. Do not substitute for
17660 other variables like $LINENOT. Do not check file dates; such a
17661 check is unreliable on sufficiently fast machines, and removing
17662 the check makes the code simpler and more reliable. Check for
17663 output and chmod failures.
17665 * doc/autoconf.texi (Special Shell Variables): Document
17668 2001-10-31 Akim Demaille <akim@epita.fr>

17675 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
17676 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
17677 provided, while it is optional.
17678 * configure.ac: Adjust.
17680 2001-10-26 Paul Eggert <eggert@twinsun.com>
17682 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
17683 lib/Autom4te/Struct.pm:
17684 Require Perl 5.005_03 instead of just 5.005, as some tests fail
17687 * doc/autoconf.texi (Special Shell Variables): Document some
17688 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
17690 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
17691 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
17692 eval $LINENO is not portable in practice.
17694 2001-10-24 Akim Demaille <akim@epita.fr>
17696 * lib/Autom4te/General.pm (backname): New.
17698 2001-10-24 Akim Demaille <akim@epita.fr>

17708 2001-10-22 Paul Eggert <eggert@twinsun.com>
17710 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
17711 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
17712 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
17713 POSIX decided to standardize on the int flavor of strerror_r.
17714 Always do char* test, as there's no reason not to.
17715 Assign to a char* var, to catch strerror_r that returns int*.
17717 * doc/autoconf.texi (Particular Functions):
17718 Document the above changes. Also, document the fact that
17719 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
17721 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
17723 2001-10-20 Akim Demaille <akim@epita.fr>

17733 * bin/autoreconf.in: No longer support --m4dir.
17734 (&autoreconf): Display the full path of the configure.ac we are
17736 Trace it only once.
17737 Be sure to honor --force with gettextize.
17738 Always run aclocal.
17739 * doc/autoconf.texi: Adjust.
17741 2001-10-20 Akim Demaille <akim@epita.fr>
17743 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
17745 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
17746 `intl' is already present, as it refuses unless --force.
17747 (&parse_args): Use -I, --include instead of the old Autoconf
17749 ($localdir, $autoconf_dir): Remove.
17751 (&maybe_autoreconf): New, to preserve $_ for File::Find.
17753 2001-10-19 Jens Petersen <petersen@redhat.com>
17755 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

17771 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
17773 * bin/autoreconf.in (autoreconf): Display the path to the
17774 configure.ac being studied.
17776 2001-10-18 Paul Eggert <eggert@twinsun.com>
17778 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
17779 long, to work around a bug in the HP C compiler version HP92453-01
17782 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
17783 (AS_BASENAME_EXPR): New macro.
17784 (AS_BASENAME_SED): Do not assume GNU sed semantics.
17785 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
17786 and fall back on 'sed' only if the other two fail. This makes
17787 AS_BASENAME act more like AS_DIRNAME.
17788 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
17789 contains white space.
17790 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
17791 Use AS_DIRNAME, since I think it's now DOS-friendly.
17792 * tests/m4sh.at (DIRNAME_TEST): New arg $3.

17844 bother with $force since...
17845 * lib/Autom4te/General.pm: does.
17847 2001-10-08 Akim Demaille <akim@epita.fr>
17849 * bin/autoreconf.in: Rewrite in Perl.
17850 * configure.ac: Adjust.

17934 empty, and if we can find a shell that does support LINENO,
17935 then set CONFIG_SHELL to that shell and then re-execute
17936 ourselves with CONFIG_SHELL.

17940 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

18022 Check for `expr' arithmetic overflow, and for compilation failure,
18023 and invoke a new argument $4 if either is discovered.
18024 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
18025 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
18027 2001-09-28 Akim Demaille <akim@epita.fr>

18059 * tests/fortran.at (GNU Fortran 77): there.
18060 * doc/autoconf.texi (autoconf Invocation): Fix the example:
18061 AC_TRY_RUN is about compilation, not shell commands.

18075 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

18243 * lib/autotest/general.m4: Englishoes.
18244 From Tim Van Holder and Alexey Mahotkin.

18250 (Limitations of Usual Tools): Refer to it when discussing dirname.
18251 Also, update discussion of POSIX standard to reflect latest draft.

18254 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
18256 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
18257 Do not pass a first argument with leading '-'
18258 to expr, by parenthesizing initial integers that might be negative.
18260 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
18261 now merely checks whether it is an error to pass an argument
18264 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
18265 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
18266 whether it is a (compile-time) error to pass an argument to
18267 getpgrp. This simpler test supports the revised documentation,
18268 and is all that AC_FUNC_GETPGRP's users really need.

18284 Add test for AS_BASENAME.
18285 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
18286 added test. It now correctly handles /1/2/3/, returning '3' not ''.
18287 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
18288 * tests/base.at: Fixed the expected responses. The old ones were
18290 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
18291 the documentation claims it should (and how it behaved in 2.13).
18293 2001-09-18 Akim Demaille <akim@epita.fr>
18295 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
18296 the AC_CONFIG_COMMANDS invocation.

18298 Don't set the package's ID.
18299 * lib/m4sugar/Makefile.am (version.m4): Revamp.
18300 No longer to be shipped.

18304 Use `m4_PACKAGE_STRING'.
18305 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
18306 the only optional argument is the name of the test suite.
18307 Expect `package.m4' to define the package signature.
18308 * lib/autom4te.in (Autotest): Add `package.m4?'.
18309 * tests/Makefile.am (package.m4): New.

18315 AC_LIBSOURCE, AC_CONFIG_FILES.

18317 program version string doesn't match the package's.
18318 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

18329 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18330 Always include <stdio.h> and <stdlib.h>. Evaluate
18331 the expression in an extra function before these includes. Call
18332 fprintf "%d" only after ensuring the argument is of type 'int'.
18333 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
18335 2001-09-17 Paul Eggert <eggert@twinsun.com>
18337 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
18338 or CFLAGS=-O5. In that case, the linker has a relaxed view of
18339 fatal errors, and AC_CHECK_LIB causes it to include libraries even
18340 when they don't exist.
18342 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
18343 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
18346 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
18347 version with the version used by fileutils 4.1, except use

18393 * lib/autotest/general.m4 (AT_INIT): Create and remove
18394 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
18395 test suites can cohabit.

18399 * tests/mktests.sh: Don't output banners for empty test files.

18505 2001-09-05 Akim Demaille <akim@epita.fr>
18507 Be ready to handle filenames as stupid as `dnl.at', for if even
18508 the maintainer is dumb enough to do that...
18510 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
18511 excellence in M4 quotation: consider `__file__' is active.
18513 And BTW, when invoking m4, pass the --include in the right order:

18567 2001-08-31 Akim Demaille <akim@epita.fr>
18569 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
18570 (Making testsuite Scripts): Update.
18572 2001-08-31 Akim Demaille <akim@epita.fr>
18574 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
18576 2001-08-31 Akim Demaille <akim@epita.fr>
18578 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
18579 (testsuite Scripts): There is no such thing as `atconfig.in'.
18580 And actually one diagram is missing: test suite runtime.
18582 2001-08-31 Akim Demaille <akim@epita.fr>
18584 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
18587 2001-08-31 Akim Demaille <akim@epita.fr>
18589 * bin/autoupdate.in (@include): `installcheck' revealed the path
18590 to m4sugar was lacking!
18592 2001-08-31 Akim Demaille <akim@epita.fr>
18594 * man/Makefile.am (.x.1): We really have to pass
18595 autom4te_perllibdir.
18597 2001-08-31 Akim Demaille <akim@epita.fr>
18599 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
18600 debug scripts, in particular passing explicitly listed tests to
18603 2001-08-31 Akim Demaille <akim@epita.fr>
18605 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
18606 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
18607 Use directly autom4te, not autoconf.
18608 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
18610 2001-08-31 Akim Demaille <akim@epita.fr>
18612 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
18613 * bin/autoheader.in (%symbol): Strip arguments of macros.
18615 2001-08-31 Akim Demaille <akim@epita.fr>
18617 * doc/autoconf.texi: Catch up -I, --include changes.
18619 2001-08-31 Akim Demaille <akim@epita.fr>
18621 * bin/autom4te.in (&parse_args): Die on unknown languages.
18622 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
18624 Promote --include over --macrodir and other obsolete options.
18626 2001-08-31 Akim Demaille <akim@epita.fr>
18628 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
18629 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
18630 * bin/autom4te.in ($autoconf): Pass --force.
18631 `print $out' doesn't print `$_' but `$out'.
18632 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
18633 (autoheader): Pass --force since the test suite goes too fast for
18635 Adjust to the new autoheader messages.
18637 2001-08-31 Akim Demaille <akim@epita.fr>
18639 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
18640 Check the completeness of the #template.
18641 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
18642 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
18645 2001-08-31 Akim Demaille <akim@epita.fr>
18647 * lib/Autom4te/General.pm (&find_file, &update_file): New.
18648 * bin/autoupdate.in, bin/autoheader.in: Adjust.
18649 Drop AC_MACRODIR dead for real.
18650 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
18651 `autoheader: `config.hin' is created'.
18652 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
18654 2001-08-31 Akim Demaille <akim@epita.fr>
18656 * bin/autoheader.in: Rewrite in Perl.
18657 * tests/autoheader: Adjust.
18659 2001-08-31 Akim Demaille <akim@epita.fr>
18661 * bin/autoconf.in (--include, -I): New option.
18662 Map --localdir, --autoconf-dir onto it.
18663 Forward autom4te's options instead of interpreting them.
18664 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
18665 There is no such envvar since the inception of autom4te.cfg.
18666 * bin/autom4te.in (&parse_args): Uniquify `@include'.
18667 * bin/autoupdate.in: Adjust, and perform more control.
18668 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
18669 * tests/autoconf: Dittowise.
18671 2001-08-31 Akim Demaille <akim@epita.fr>
18673 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
18674 * bin/autom4te.in (&find_file): Support `FILE?' standing for
18676 Use -e, not -f, since /dev/null for instance is OK.
18677 (&parse_args): Adjust.
18678 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
18680 2001-08-31 Akim Demaille <akim@epita.fr>
18682 * configure.ac: Also find tested executables in bin.
18683 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
18684 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
18685 installed peer executables, only PATH is allowed to resolve it.
18686 Pass `autoconf_dir' via options, not via invisible envvars.
18687 * lib/Autom4te/General.pm (&find_peer): Remove.
18688 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
18689 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
18690 * man/Makefile.am: Let help2man rely on PATH instead of trying to
18691 find the executables for it.
18692 * tests/Makefile.am: Major cleanup. Too lazy to document...
18693 * tests/atlocal.in: Remove all the obscure envvar manipulations.
18695 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
18696 indeed related to running the test suite, while passing
18697 --autoconf-dir and others is related to running non installed
18698 Autoconf executables. So don't do that, leave it to...
18699 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
18700 * tests/autoscan: New.
18701 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
18702 refer to library files: rely on --language.
18704 2001-08-29 Akim Demaille <akim@epita.fr>
18706 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
18707 s/--set/--language/.
18709 2001-08-29 Akim Demaille <akim@epita.fr>
18711 * doc/autoconf.texi: Strip the @nodes.
18712 Suggested by Paul Eggert.
18713 (Initializing configure): Typo.
18715 2001-08-29 Akim Demaille <akim@epita.fr>
18717 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
18718 Suggested by Paul Eggert.
18720 2001-08-29 Akim Demaille <akim@epita.fr>
18722 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
18723 download in a tmp dir.
18725 2001-08-29 Akim Demaille <akim@epita.fr>
18727 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
18728 case insensitive OSes out there :(
18729 From Tim Van Holder.
18731 2001-08-29 Akim Demaille <akim@epita.fr>
18733 * lib/autom4te.in: New.
18734 * lib/Makefile.am (edit, autom4te.cfg): New.
18735 * bin/autom4te.in (BEGIN): Simplify.
18736 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
18737 (&load_configuration): New. Use it.
18738 (&parse_args): Support --mode, --set, and --melt.
18739 * bin/autoconf.in: Simplify and adjust.
18740 * tests/Makefile.am (AUTOMAKE): Use --set.
18741 * tests/atlocal.in: Adjust.
18742 * BUGS: distcheck and check are weak.
18744 2001-08-29 Akim Demaille <akim@epita.fr>
18746 * lib/autotest/general.m4: Use
18747 foo=`(command) 2>/dev/null`
18749 foo=`command` 2>/dev/null
18750 (at-devnull): Rename as...
18751 (AT-devnull): this.

18773 2001-08-27 Akim Demaille <akim@epita.fr>
18775 * Makefile.maint: Formatting changes.

18788 * lib/autotest/general.m4 (AT_INIT): Log the command line.
18789 Support `VAR=VAL' as arguments.

18819 * doc/autoconf.texi (Input) <AC_INIT>: Move to..

18897 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
18898 the name of the directory they're in, instead of the filename,
18899 since version.m4 is now in m4sugar, but m4_acversion must not be
18900 classified as an Autoconf macro.

18902 Rather, pass autoconf_dir to m4.

18923 Use the same log introduction as configure's.
18925 2001-08-22 Paul Eggert <eggert@twinsun.com>
18927 * doc/autoconf.texi (Indices): New node.

18987 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
18988 * NEWS, README, README-alpha, TODO, tests/README: This package is
18989 `Autoconf', not `autoconf' (the executable).
18991 2001-08-20 Akim Demaille <akim@epita.fr>
18993 Info readers seem to need `Index' in the index node title :(

19002 * doc/autoconf.texi (Input) <AC_INIT>: Arguments must be literals.
19003 Specify the output variables, and macros defined.
19005 2001-08-20 Akim Demaille <akim@epita.fr>
19007 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
19008 (Examining Syntax) <AC_TRY_COMPILE>

19127 * doc/autoconf.texi: Work around Texinfo buglets.

19188 * Makefile.am: Ditto (but maintainer-clean-local).
19190 2001-08-15 Akim Demaille <akim@epita.fr>
19192 * bin/autom4te.in (@m4_warning): New.
19193 (&handle_m4): Use it.
19194 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
19195 warnings are issued at each run.
19196 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
19197 is in the src tree.
19199 2001-08-15 Akim Demaille <akim@epita.fr>

19264 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
19266 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
19267 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
19268 * doc/autoconf.texi (C Compiler Characteristics): Update

19274 magic values from an object file when cross-compiling.
19275 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
19277 2001-08-10 Akim Demaille <akim@epita.fr>
19279 * bin/autom4te.in (&handle_output): Don't use `grep' with side
19281 Suggested by Russ Allbery.
19283 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
19285 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
19286 current $prefix to the sub-configures.
19288 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
19290 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
19291 extension (needed on BeOS). Reported by Guido van Rossum.
19293 2001-08-09 Akim Demaille <akim@epita.fr>
19295 * bin/autom4te.in ($icache): Load it only if older than autom4te.
19297 2001-08-07 Akim Demaille <akim@epita.fr>
19299 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
19301 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
19302 No need to remove the files before and after the each test, before
19303 each test and at the end of the suite is enough.
19304 Display only the children `times', not the shell's.
19305 If the test failed or was skipped, at-times is not available.
19307 2001-08-07 Akim Demaille <akim@epita.fr>
19309 Always produce testsuite.log, including when there are no
19310 failures. This helps getting information on skipped tests, and
19311 duration of the tests. Err, implement the latter btw.
19313 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
19314 Dump information on the first run of each test.
19315 (AT_CLEANUP): Create `at-times' containing the duration of the
19318 2001-08-07 Akim Demaille <akim@epita.fr>
19320 The use of `dumpstat' revealed that `len' was used although it
19321 should not. m4_text_wrap was using it, but in the Autoconf world
19322 where it is legal. Hence (i) test M4sh in its own world, not
19323 Autoconf's, and (ii), ahem, fix the bug :)
19325 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
19326 does not like `' instead of [].
19327 (AT_INIT): Forbid `^_?AT_'.
19328 And don't output such tokens.
19329 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
19330 `script.as', and `autom4te.cache'.
19331 Remove `empty' and `macro' which are no longer used.
19332 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
19333 * tests/m4sugar.at: Use it.
19334 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
19336 2001-08-07 Akim Demaille <akim@epita.fr>
19338 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
19340 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
19342 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
19344 2001-08-04 Akim Demaille <akim@epita.fr>
19346 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
19347 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
19349 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
19350 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
19351 (AC_F77_MAIN): Likewise.
19353 2001-08-04 Akim Demaille <akim@epita.fr>
19355 Don't rely on M4sugar outputting the patterns in files, since we
19356 might process the output _without_ running m4, hence without these
19359 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
19360 * bin/autom4te.in (@Request::includes): Remove, unused.
19361 (@Request::source): Rename as...
19362 (@Request::input): this.
19363 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
19364 (&handle_output): Fetch the patterns from the traces.
19365 `$forbidden' and `$allowed' are constant: use m//o.
19366 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
19367 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
19369 2001-08-04 Akim Demaille <akim@epita.fr>
19371 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
19372 autoconf', i.e., in addition to caching traces, cache the output.
19374 * bin/autom4te.in (Request::cache): Rename as...
19375 (Request::id): this.
19376 ($cache, $icache, $tcache, $ocache): New.
19377 (&handle_m4): Save M4 output in the cache instead of $tmp.
19378 (&handle_output): Adjust.
19379 (&up_to_date_p): Check that the output cache is up to date too.
19380 (top level): Run `&handle_m4' iff force or the cache is invalid.
19381 Run `&handle_output' if the output cache is more recent.
19383 2001-08-04 Akim Demaille <akim@epita.fr>
19385 * bin/autom4te.in ($force): New.
19386 (&parse_args, &print_usage): -f, --force is a new option.
19387 (&handle_output): CPP directives might have spaces after `#'.
19388 (&parse_args): The first file only can be frozen.
19390 2001-08-04 Akim Demaille <akim@epita.fr>
19392 Don't let autom4te compute the `include' traces several times:
19393 first check that the trace cache file is up to date, and then
19394 compare its timestamp with that of the output.
19396 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
19397 the preamble. Don't require 5.005 as Autom4te::General does it,
19398 and better yet (use `use', not `require'!).
19399 * lib/Autom4te/Struct.pm: Rename the last occurrences of
19400 Class::Struct as Autom4te::Struct.
19401 * lib/Autom4te/General.pm (File::stat): Use it.
19402 (&mtime): New, export it.
19403 * bin/autom4te.in: Use it.
19404 Declare `$req' is invalid if it is outdated.
19405 Don't declare it valid before saving it if something went wrong.
19407 2001-08-04 Akim Demaille <akim@epita.fr>
19409 Autom4te shall not encode Autoconf data, and preselecting traces
19410 must be proposed to the users.
19412 * bin/autom4te.in (@required_trace): Remove.
19414 (&parse_args, &print_usage): -p, --preselect is a new option.

19420 * tests/tools.at (autoconf --trace: user macros): Check traces on
19421 macros invoked without arguments, and macros invoked with multiple

19431 * bin/autoconf.in ($@): Work around the usual sh bug.
19434 2001-08-03 Akim Demaille <akim@epita.fr>
19436 Clean up the handling of the M4 builtins tracing exception.
19438 * bin/autom4te.in (Request::request): Don't complete M4 builtins

19441 (@m4_builtin): this.
19442 (%m4_builtin_alternate_name): New.
19443 (&parse_args): Complete the trace requests with alternate names.
19444 (&handle_traces): Hence no longer do it here.

19455 (m4_divert_pop): Dump the whole diversion stack when a diversion
19457 * bin/autom4te.in (&handle_output): Remember of the first
19458 occurrence of a possibly undefined macro, not the last.
19459 Complain about the possibly undefined macros in the same order as
19460 the appear in the output.
19461 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
19462 * tests/tools.at (autoconf: forbidden tokens, basic)
19463 (autoconf: forbidden tokens, exceptions): No longer sort
19464 autoconf's stderr, as it is now deterministic.
19465 Check that `dnl' is caught.
19467 2001-08-01 Akim Demaille <akim@epita.fr>
19469 * configure.ac: Bump to 2.52c.
19471 2001-08-01 Akim Demaille <akim@epita.fr>
19475 * lib/Autom4te/Makefile.am (perllibdir): s/Autoconf/Autom4te/.

19481 2001-08-01 Akim Demaille <akim@epita.fr>
19483 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
19486 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
19487 `END', as `Autom4te::General::END' will be triggered.
19488 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
19489 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
