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

190 DJGPP fix: remove both conftest and conftest.exe.
191 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
192 and both `conftest' and `conftest.exe' with `-o conftest', but not
193 with `-o conftest.exe'.
194 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Also remove
195 `conftest' without $ac_exeext suffix.

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

5055 (autotools and whitespace in file names): Use them.
5056 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5057 Cover more potentially problemtic file names. Use the new
5060 Properly handle funny file names for headers in config.status.
5061 The test suite did not cover this bug because the code was not
5062 quoting properly the arguments of `rm -f' (which "fails" silently)
5063 as well as the arguments of `diff' (whose output was redirected to
5064 /dev/null so we couldn't see its error message).
5065 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
5066 file names passed to `rm' and `diff'.
5067 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

5179 Add 'testsuite -C dir'.
5180 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
5182 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
5184 <DEFAULTS>: Delay computation of variables based on $at_dir...
5185 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
5186 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
5187 <PARSE_ARGS>: Parse new option.
5188 <HELP_TUNING>: Document it.
5189 * tests/autotest.at (Choosing where testsuite is run): New test

5198 build-aux/texinfo.tex: Sync from gnulib.

5204 * doc/autoconf.texi (Particular Programs): Do not mention the
5205 Autoconf version in which the AC_PROG_INSTALL change was done.
5206 Suggested by Paul Eggert.
5208 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5210 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
5211 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
5212 mode, we change to the source directory, also set $ac_pwd so we
5213 do not go back to the build tree for the next config subdir.
5214 * tests/torture.at (Deep Package): Extend test to contain two
5215 config subdirs on the top level.
5217 Fix parallel `maintainer-check'.
5218 * Makefile.am (maintainer-check-tests): Depend on `all'.
5219 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.

5248 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
5249 check_SCRIPTS. Building the wrappers for `all' allows help2man
5250 to use them for the manpages.
5251 Report by Benoit Sigoure.
5253 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
5255 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5269 (m4_require): Use m4_do, not m4_join.
5271 Fix some whitespace tests on cygwin.
5272 * tests/tools.at (autom4te and whitespace in file names): Restore
5273 font-lock. Create $TMPDIR before it might be used.
5275 Fix spurious testsuite failure with M4 1.4.11.
5276 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
5278 Optimize AC_REQUIRE.
5279 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)

5281 (m4_require): Avoid extra macro calls.
5283 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5285 * tests/torture.at (srcdir): Fix quoting.
5287 Do not pass top_srcdir to configure scripts in testsuite.
5288 * tests/autotest.at (srcdir propagation): Copy install-sh to
5290 (my only test): Drop setting of `top_srcdir'.
5291 * tests/base.at (Input/Output): Likewise.
5292 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
5293 config.guess, and config.sub to test source tree.
5294 Drop AC_CONFIG_AUX_DIR setting.
5295 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
5296 * tests/torture.at (Substitute a 2000-byte string): Drop
5297 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
5298 (Substitute a newline, datarootdir workaround): Likewise.
5299 (Define a newline): Adjust for linenumber changes in configure.ac.
5300 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
5302 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
5303 if `pwd` contains whitespace.

5307 * tests/tools.at (Syntax of the shell scripts): Likewise.
5309 * tests/m4sh.at (LINENO): Quote $0.
5311 Fix testsuite program wrapper for whitespace in `pwd`.
5312 The problem here is that the usual mantra is that command
5313 variables can contain arguments, thus we cannot just escape
5314 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
5315 $top_builddir/tests directory early in $PATH, so that the
5316 wrappers are found by their plain name.
5317 * tests/wrapper.as: Put $testdir early in $PATH.
5318 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
5320 Proper config.status --file/--header and $srcdir escaping.

5330 <at_func_create_debugging_script, Driver Loop>:
5331 Quote $at_group_dir.
5332 * tests/autotest.at (whitespace in absolute testdir): New test.
5334 * lib/autom4te.in: Quote @datadir@.
5336 Proper file name escaping in Autoconf programs and Perl modules.
5337 This includes escaping of characters special to the shell
5338 as well as special to Perl, e.g., leading `<' or `>'.
5339 For example, when $file starts with `>', `open ">$file"'
5340 wrongly tries to append to a different file.
5341 * bin/autoconf.as: Fix quoting for autom4te options.
5342 * lib/Autom4te/General.pm (shell_quote): New function, taken
5343 from coreutils, written by Jim Meyering.
5345 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
5347 * bin/autoreconf.in (parse_args): Likewise.
5348 * bin/autoscan.in (main): Likewise.

5351 * bin/ifnames.in: Likewise, XFile usage fixes.
5352 * tests/tools.at (autom4te and whitespace in file names): Extend
5353 test. Test twice, with special characters allowed on w32, and the
5354 rest. Test leading and trailing whitespace, for `open_quote'.
5355 (autotools and whitespace in file names): New, analogous test.
5356 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
5357 by Russ Allbery and Eric Blake.
5360 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
5361 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
5362 * lib/Autom4te/FileUtils.pm (open_quote): New function.
5363 (update_file, contents): Use it.
5365 * Makefile.am (autom4te-update): Rewrite for git.
5367 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5369 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
5371 Fix copyright years.
5372 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
5373 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
5375 2007-12-04 Eric Blake <ebb9@byu.net>
5377 Manually resync with gnulib, since 'make cvs-update' no longer works.

5383 * doc/Makefile.am (TEXINFO_TEX): Add.
5385 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
5387 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
5388 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
5389 #undef as this runs afoul of our new way of creating config.h.
5390 Problem reported by Jim Meyering in
5391 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

5395 Fix autom4te for unusual characters in input file names.
5396 * bin/autom4te.in (files_to_options): Quote active characters
5398 * tests/tools.at (autom4te and white space in file names):
5401 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
5402 Document that Tru64 awk always splits $0.
5404 2007-11-24 Stepan Kasal <kasal@ucw.cz>
5406 * lib/autotest/general.m4 (AT_INIT): Do not extract the
5407 `#AT_STOP_...' line at the end of each test.
5409 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5411 * lib/autotest/general.m4 (AT_INIT): For awk line number
5412 extraction script, ensure `$at_group' has a defined value
5413 even for the empty set, and properly quote its usage inside
5416 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5418 * doc/autoconf.texi (Shell Functions): New chapter. Document
5419 IRIX sh $0 issue in functions, move content from ...
5420 (Portable Shell): ... here.
5421 (Shell Script Compiler): Note that shell functions are not
5422 totally unportable any more.
5424 2007-11-22 Stepan Kasal <kasal@ucw.cz>
5425 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5427 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
5428 extracting the line numbers of the last needed test.
5430 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5435 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5437 Fix IRIX testsuite debugging failures: $0 in functions.
5438 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
5439 Do not use $0 inside a function, as IRIX sh will set that to the
5440 function name rather than the script invocation name.
5442 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
5443 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5445 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
5446 to extract test scripts.
5447 (AT_INIT): Extract and cache test script line numbers.
5449 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5451 * lib/autotest/general.m4: Revert 2007-11-15 patch and
5452 subsequent fixups; the awk -> here-document conversion trashes
5453 performance too much with AIX sh.
5455 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5457 * tests/local.at: Do not test m4, perl with AT_TESTED.
5459 Diagnose and guard against write errors dealing with config.status.
5460 The general idea is this: all write failures from `configure'
5461 writing `config.status' are indicated by $ac_write_error, which
5462 is only checked at the end. This is safe because config.status
5463 code is not executed before the file is complete. Other write
5464 failures, be they inside config.status, or in sub shell/awk
5465 scripts spawned from configure or config.status, typically need
5466 earlier checking, as their results are used right afterwards.
5467 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
5468 before writing config.status, check afterwards.
5469 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
5470 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
5471 Set `ac_write_error' for write failures to config.status. Barf
5472 upon write failures to temporary files.
5473 Adjust note about closing and reopening the here-document.
5474 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
5475 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
5476 reopening the here-document.
5477 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5478 Ensure `ac_write_error' does not escape into config.status.
5479 Also, add a couple of code paths not yet exercised in the test
5480 suite: a config file with input from stdin, and a config header
5482 Suggestion for catching write errors by Bruno Haible.
5484 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5486 Avoid error with Tru64 awk and testsuite lines with many words.
5487 * lib/autotest/general.m4 (AT_INIT): In the awk script that
5488 reads the testsuite, set the field separator to an unusual value,
5489 in order to not run over the limit of 199 fields. Tru64 4.0D awk
5490 even splits the input if $i, i>0, was never accessed in the script.
5492 Revert 2007-10-17 change.
5493 * TODO: Multiline args in config files and headers mean something
5494 different and are not fixed, see
5495 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
5496 Report by Stepan Kasal.

5500 2007-11-16 Stepan Kasal <kasal@ucw.cz>
5502 AC_*_TOOL does not canonicalize the prefix
5503 * doc/autoconf.texi (Generic Programs): Do not say that
5504 the *_TOOL macros canonicalize, they simply use the `host_alias'.
5506 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5508 Diagnose write errors in config.status instantiations.
5509 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
5510 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
5512 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5513 Extend test to also check for some write error failures, using...
5514 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
5515 Report by Bruno Haible.
5518 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
5520 (_AT_CHECK): Use less indentation, to save space.
5522 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5524 Add witness macro for @top_build_prefix@ substitution.
5525 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
5526 (_AC_OUTPUT_FILE): Mention it here.
5528 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
5529 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5531 * lib/autotest/general.m4 (at_func_test): Remove.
5532 (AT_INIT): Pre-extract test groups into separate files.
5533 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
5534 Remove at-test-source files together with the $at_group_dir.
5535 * tests/autotest.at (Long test source lines): New test.
5537 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5539 Shell functions and variables may share a namespace.
5540 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
5543 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
5545 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
5548 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5550 * lib/autoconf/status.m4: Fix a couple of comment typos.
5552 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
5554 2007-11-13 Jim Meyering <meyering@redhat.com>
5556 Clean up the rule to create "expr".
5557 * tests/Makefile.am (expr): Don't redirect directly to target.
5558 Redirect just once, not for each echo statement.
5559 Use $@, not literal "expr".
5561 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
5563 Don't worry about preprocessor when testing long long.
5564 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
5565 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
5566 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
5567 These no longer check for preprocessor flaws.
5568 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
5569 Do not check for preprocessor flaws.
5571 2007-11-13 Jim Meyering <meyering@redhat.com>
5573 Adapt dependencies, now that a version change doesn't modify configure.ac
5574 * GNUmakefile: Remove "make clean" kludge.
5575 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
5577 Don't redirect directly to target.
5578 Use $@, not literal "version.m4".

5583 ":;{" shorthand as in previous patch.
5585 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
5587 * doc/autoconf.texi (Limitations of Builtins): Document problem
5588 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
5590 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
5591 Use ":;{" shorthand.
5592 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
5594 2007-11-12 Jim Meyering <meyering@redhat.com>
5596 Add more non-srcdir build support.
5597 * GNUmakefile (dummy): Split a long line.
5598 Add -v option to autoreconf invocation.
5600 Remove the autoreconf-provided INSTALL, so that we regenerate it.
5601 * GNUmakefile (dummy): Remove INSTALL.
5603 Remove racy commands to build scripts in bin/ and tests/.
5604 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
5605 are guaranteed to be built, remove the rules that tried to build
5606 them. Before, with a parallel build, these rules could lead to
5607 two processes writing tests/wrapper.in concurrently.
5609 Build in man/ only *after* building in bin/ and tests/.
5610 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
5611 in both bin/ and tests/.
5613 Accommodate non-srcdir build-from-checkout.
5614 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
5615 Use git's --git-dir=$srcdir/.git option.
5616 Add quotes, in case tarball_version_file contains shell meta-characters.
5617 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
5618 * configure.ac: Pass "." to git-version-gen.
5620 Avoid spurious test failures due to version skew.
5621 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
5623 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5625 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
5626 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
5627 Remove conftest.dSYM directory.
5628 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
5629 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
5630 Remove `conftest.*' recursively.

5632 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
5634 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
5636 Report and analysis by Jeff Squyres and Peter O'Gorman.

5640 Fix typos in variable names.
5641 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
5643 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
5645 Document that $((expression)) is not portable.
5646 * doc/autoconf.texi (Shell Substitutions): Here.
5648 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5650 Ignore configure --help* errors due to LINENO-impaired shells.
5651 * tests/torture.at (Configuring subdirectories, Deep Package):
5652 In the --help* tests in read-only trees, make `.' temporarily
5653 writable again for the `stderr' file, and ignore errors due to
5654 the attempt to write configure.lineno.
5655 Report by Patrick Welche.
5657 2007-11-10 Jim Meyering <meyering@redhat.com>
5659 Generate package.m4 in build-dir, not srcdir.
5660 * tests/Makefile.am (package.m4): Adjust target.
5661 Don't redirect directly to $@.
5662 (CLEANFILES): Add package.m4.
5663 ($(TESTSUITE)): Depend on just-built package.m4, not the one
5665 When running $(AUTOTEST), search "." before searching $(srcdir).
5667 Avoid a race condition that would make parallel "distclean" fail.
5668 * tests/Makefile.am (distclean-generic): Replace the default,
5669 automake-provided rule with an identical one, but with an additional
5670 dependency on distclean-local. Simply adding the dependency would
5671 cause automake not to emit the rule at all.
5672 * BUGS: Building with -jN works, now.
5674 Distribute git-version-gen.
5675 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
5676 since GNUmakefile is distributed, and requires it for dist* rules.
5678 Remove two more generated files from version control.
5679 * INSTALL: Remove generated file.
5680 * lib/autoscan/autoscan.list: Remove generated file.
5682 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
5684 * GNUmakefile (PATH): Remove stray apostrophes; they become
5685 part of PATH, which isn't wanted here.
5687 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5689 New config files output variable `top_build_prefix'.
5690 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
5692 * doc/autoconf.texi (Preset Output Variables): Document it.
5694 Report by Bob Friesenhahn.
5696 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
5697 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
5698 function, to parametrize arithmetic with expr vs. the shell.
5699 Use it where possible.
5700 Suggestion by Benoit Sigoure.
5702 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
5704 Adjust the documentation of autotest WRT atlocal.
5705 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
5706 when using Automake, to write a rule to produce atlocal, since it's
5707 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
5708 distributed, not atconfig.in.
5710 2007-11-04 Eric Blake <ebb9@byu.net>
5712 Update list information.
5713 * README: Mention new autoconf-commit list.

5720 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
5722 * build-aux/.gitignore: Ignore mkinstalldirs.
5724 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
5726 2007-11-03 Jim Meyering <meyering@redhat.com>
5728 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
5729 * build-aux/git-version-gen: This syncs from coreutils.
5731 Adjust the build procedure so "make check" works reliably.
5732 * README-hacking: Include an extra step between "make" and
5733 "make check" to ensure that the latter passes.
5735 Use just-built tools, when possible.
5736 * GNUmakefile (PATH): Set and export here, ...
5737 (dummy): ... rather than here.

5777 2007-11-03 Eric Blake <ebb9@byu.net>
5779 Adjust version comparison to account for git snapshot numbers.

5783 <m4_version_compare>: Document this change.
5784 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
5786 2007-10-30 Bruno Haible <bruno@clisp.org>
5788 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
5789 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
5790 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
5791 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
5792 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
5793 Suggested by Paul Eggert.
5795 2007-10-28 Jim Meyering <meyering@redhat.com>
5797 * README-hacking: Autoconf, Automake, and Perl are required to build.
5798 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
5800 2007-10-28 Jim Meyering <meyering@redhat.com>
5802 README-hacking: Recommend running autoreconf -vi.
5803 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
5804 so that we use just-built tools when they're available.
5805 Suggestions from Ralf Wildenhues.
5807 2007-10-28 Jim Meyering <meyering@redhat.com>
5809 Make inter-release --version output more useful.
5811 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
5812 which indicates that it is built using the 19th change set
5813 (in _some_ repository) following the "v2.61a" tag, and that 58dd
5814 is a prefix of the commit SHA1.
5815 * build-aux/git-version-gen: New file.
5816 * configure.ac: Run it to set the version.
5817 (AM_INIT_AUTOMAKE): Don't check NEWS here.
5818 * Makefile.am (dist-hook): Arrange so that .version appears only
5819 in distribution tarballs, never in a checked-out repository.
5820 * .gitignore: Add .version here, too. Just in case.
5821 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
5822 not configure.ac, now that the version number changes automatically.
5824 Ensure that $(VERSION) is up to date for dist-related targets.
5825 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
5826 git-version-gen doesn't match $(VERSION), but only for dist targets.

6936 2007-06-12 Noah Misch <noah@cs.caltech.edu>
6938 * lib/autoconf/general.m4 (AC_SUBST): Raise a fatal error if VARIABLE is
6939 not a valid shell variable name.

6977 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp
6978 choice, since that's what we do with --enable-largefile etc.

7082 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
7083 for a.* when searching for executables, as this prevents users

7096 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
7097 AC_CHECK_TYPE, AC_CHECK_TYPES.
7098 * doc/autoconf.texi (Generic types): C types must be type-names
7099 (the C terminology), not type-ids (the C++ term). C++ types
7100 must not be anonymous.
7101 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
7102 for C++; this drops support for anonymous struct and union types,
7103 which were problematic anyway.

7120 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
7121 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
7122 with objects too. Document the restrictions on its use.
7123 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
7124 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
7125 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
7126 works but the latter doesn't, then it's a valid type.
7127 This lets people use function types and so forth.
7128 For C++ there doesn't seem to be a simple solution, so leave it alone.
7129 (AC_CHECK_SIZEOF): Allow argument to be a variable.
7130 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
7131 AC_CHECK_TYPE; that wasn't documented or necessary.
7133 2007-04-11 Stepan Kasal <kasal@ucw.cz>
7135 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

7186 2007-03-17 Jim Meyering <jim@meyering.net>
7188 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
7189 (Limitations of Usual Tools): Also list \< and \>, and mention that

7301 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
7302 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
7303 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
7304 substitution will still be done by the special code.

7328 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
7329 early on the reader side, drop stderr of the input to avoid
7330 `broken pipe' error output; this may happen even with shell
7331 builtin `echo' of some bash versions. Reports by Ian Macdonald

7348 * doc/autoconf.texi (Signed Overflow Examples): Give more
7349 discussion about the allow_superuser_privileges example,
7350 and change it a bit to make things clearer.
7351 (Optimization and Wraparound): Clarify whether the compiler
7352 will generate an infinite loop for the example derived from
7353 Autoconf's mktime test.
7354 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
7355 Also, clarify unsigned multiplication overflow.
7357 2007-01-04 Eric Blake <ebb9@byu.net>
7359 * bin/Makefile.am (RELEASE_YEAR): New macro.
7360 (edit): Use it to supply correct copyright year to scripts.

7362 * bin/autoheader.in ($version): Likewise.
7363 * bin/autom4te.in ($version): Likewise.

7369 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
7371 * doc/autoconf.texi (Integer Overflow): Revised based on today's
7372 feedback. The most important changes document what happens when
7373 you convert an out-of-range value to a signed integer type, and
7374 say that (sum < a) != (b < 0) reliably detects overflow when sum =
7377 * doc/autoconf.texi (Integer Overflow): Greatly expand and
7378 rewrite, taking notions from the recent discussion on the gcc and
7379 autoconf mailing lists; please see
7380 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
7381 and follow the many links.
7382 (Integer Overflow Basics, Signed Overflow Examples):

7384 (Signed Integer Division): New sections.
7386 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
7388 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
7389 preprocessor macro arguments in traced name.
7390 * doc/autoconf.texi (Defining symbols): Document longstanding
7391 support for AC_DEFINE-ing macros with arguments, and document
7392 behavior when the same variable has multiple AC_DEFINEs.
7393 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
7394 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
7395 macros directly, giving much shorter and simpler code.
7397 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
7399 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
7400 space before "$ac_configure_args" to prevent a 'config.status
7401 --recheck' failure if ac_configure_args doesn't contain a leading
7402 space. This works around a problem with the XEmacs configure.ac,
7403 which uses the (undocumented) ac_configure_args variable
7404 inconsistently with Autoconf.
7406 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
7408 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
7409 Include <limits.h>, and use its INT_MAX to rewrite the
7410 j loop so that it does not overflow 'int'. Problem reported by
7412 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
7413 Play it safe by shifting left by 1 rather than multiplying by 2,
7414 as GCC is less likely to optimize this away when the value
7415 is signed (when it assumes overflow leads to undefined behavior).
7416 Also, don't assume time_t uses two's complement.
7418 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7420 * tests/torture.at (Substitute a 2000-byte string): Avoid using
7421 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
7422 dumps core on it. Report by Tim Rice.
7424 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7426 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
7427 --disable-option-checking to --help output even when
7428 AC_PRESERVE_HELP_ORDER is not used.
7429 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
7430 --with argument, rather than argument with [-.] replaced by
7432 * NEWS: Fix typo in previous change; the news was in the
7435 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
7437 * NEWS: Warnings are now generated by default for unknown
7438 --enable-* and --with-* options.
7439 * doc/autoconf.texi (Option Checking): Renamed from
7440 (Configure Option Checking). Tighten up the wording a bit.
7441 (External Software, Package Options): Cross-reference to Option
7442 Checking, and use this to shorten our section.
7443 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
7444 "$x" to test "x$foo" != x.
7445 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
7446 Don't warn if $enable_option_checking is "no".
7447 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
7448 ac_unrecognized_opts to the empty string.
7449 Don't echo the unrecognized opts, as this might mishandle
7450 backslashes or leading -.
7451 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
7452 usage next to the other --disable-FEATURE options in the
7455 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7457 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
7458 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
7459 Print warning for unrecognized --with and --enable options
7460 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
7461 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
7462 Disable option checking when subdirs are configured.
7463 (AC_OUTPUT): If warnings are enabled, print warning about
7464 unrecognized --with and --enable options at the end of
7465 the configure output (as well as at the beginning).
7466 * doc/autoconf.texi (Option Checking): New node.
7467 Document new option warning functionality.
7469 2006-12-16 Eric Blake <ebb9@byu.net>
7471 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
7472 * NEWS: Start news for current version.
7474 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
7476 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
7477 Define HAVE_GETMNTENT to 1, not to the empty string.
7478 Problem originally reported by Jochen Friedrich in
7479 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
7481 This change prompted by a problem report by Andrey Simonenko in
7482 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
7483 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
7484 object-like macros only, in the traditional portable character
7486 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
7487 Warn about attempts to define things that are not identifiers.
7488 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
7489 awful hack that AC_DEFINEd macro names containing parentheses.
7491 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
7493 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
7494 too drastic, even if Texinfo in theory requires it for info mode.
7496 (config.status Invocation): Renamed back from Recreating a
7498 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
7499 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
7501 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7503 * NEWS: Version 2.61a.
7505 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7506 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7508 * NEWS: Document changes with echo and printf, and the lack
7509 of limits on the total size of multi-line values of substituted
7510 variables, and the AC_FUNC_FSEEKO fix.
7512 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
7514 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
7515 Writing configure.ac.
7516 (Autoconf Input Layout): Renamed from configure.ac Layout.
7517 (Recreating a Configuration): Renamed from config.status Invocation.
7518 (Obsolete Recreation): Renamed from Obsolete config.status Use.
7519 (acconfig Header): Renamed from acconfig.h.
7520 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
7521 (Writing Testsuites): Renamed from Writing testsuite.at.
7522 (Autom4te Cache): Renamed from autom4te.cache.
7524 * BUGS: Remove mention of VPATH problem, since it's now documented
7525 not to be a bug in the Autoconf build procedure itself, but rather
7526 a problem with the proprietary `make' programs.
7528 * doc/autoconf.texi (Build Directories): Add a cross reference
7531 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
7532 * doc/standards.texi: Sync from gnulib.
7534 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
7535 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
7536 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
7537 generated automatically.
7539 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
7541 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
7542 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
7543 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
7545 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7547 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
7548 `CEOF$ac_eof' special marker, the awk script cannot contain a
7549 line matching `^CEOF', so this is not needed any more.
7550 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
7551 special marker in the test.
7553 2006-12-06 Stepan Kasal <kasal@ucw.cz>
7555 * tests/tools.at (autom4te preselections): Use `find -newer';
7556 remove one of the sleeps.
7558 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
7559 more readable, using ...
7560 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
7562 * doc/autoconf.texi (autoheader Invocation): Do not double-
7563 quote the parameter of `AH_BOTTOM' in the example.
7565 2006-12-05 Stepan Kasal <kasal@ucw.cz>
7567 * doc/autoconf.texi (Configuration Headers): Remove the
7568 example with multiple input files.
7569 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
7570 multiple input files.
7572 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7574 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
7575 creating the awk substitution script, handle one input line at a
7576 time, so that the maximum length of a substituted (multi-line)
7577 value is not limited by the size of the sed pattern space.
7578 The trade-off is a slightly repetitive sed script.
7579 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
7580 can only have up to 7 characters, due to Solaris 10 /bin/sed.
7581 * tests/torture.at (Substitute a 2000-byte string): Increase the
7582 test with several long lines, they should not be caught by sed
7585 * tests/tools.at (autom4te preselections): New test, to flag
7586 entries missing from autom4te.cfg.
7587 Report by David Byron <dbyron@hheld.com>.
7589 * tests/torture.at (Substitute a 2000-byte string): Actually use
7590 AC_PROG_AWK, so the last change works as intended.
7591 (Substitute and define special characters): Likewise.
7592 (Substitute a newline): Likewise.
7594 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
7595 instead of `awk' consistently.
7596 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
7597 * tests/torture.at (Torturing config.status): Test both the
7598 result of AC_PROG_AWK and plain awk.
7599 (Substitute a 2000-byte string): Likewise.
7600 (Substitute and define special characters): Likewise.
7601 (Substitute a newline): Likewise.
7603 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
7605 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
7606 can be assigned to a function pointer. Problem reported by
7607 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
7608 part of a patch by Ralf Wildenhues in that same bug report.
7610 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
7612 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
7613 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
7615 2006-12-01 Eric Blake <ebb9@byu.net>
7617 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
7618 cross-compiling from cygwin to mingw.
7619 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
7620 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
7621 to lib/autoconf/c.m4.
7623 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7625 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
7626 string for more reliable failure. Wrap the entire test that
7627 causes the broken Solaris printf to dump core, in a subshell,
7628 so the segmentation fault message is reliably suppressed.
7629 Fix shell expansion errors by using /usr/ucb/echo always;
7630 avoid an error on systems without it by another subshell.
7631 Avoid m4 expansion of `$1'. Set the zeroth argument of the
7632 subshell-$as_echo to `as_echo', for better error message.
7634 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7636 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
7637 `BASH_SOURCE' contain a newline, set them to empty, as they may
7640 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
7642 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
7643 years and is too hard to maintain now. The last straw was
7644 reported by Jerker Baeck in
7645 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
7646 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
7647 * doc/autoconf.texi (Particular Functions): Move
7648 AC_FUNC_SETVBUF_REVERSED from here...
7649 (Obsolete Macros): ... to here. Say that it does nothing now.
7650 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7651 Turn into (almost) a no-op.
7653 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
7655 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
7656 These macros are obsolescent and new applications shouldn't need them.
7657 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
7658 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

7663 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
7664 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
7666 * doc/autoconf.texi (Setting Output Variables): Mention that
7667 @VAR1@VAR2 has unspecified behavior. Problem reported by
7669 * NEWS: Mention this.
7671 * Makefile.am: Put only a single '#' into the copyright notice,
7672 so that it's also present in the output file. Standardize wording
7673 in makefile copyright notices to match GNU coding standards.
7674 * bin/Makefile.am: Likewise.

7687 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7689 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
7690 in the sed script that mangles the awk script: delete up to the
7691 first exclamation mark only.
7692 * tests/torture.at (Substitute and define special characters):
7695 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7697 Rewrite config files generation: avoid quadratic growth in
7698 the number of substituted variables by using awk instead of sed
7699 for the bulk of the substitutions.
7700 * NEWS: Mention this.
7701 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
7702 forbidden in the output (and thus input) file.
7703 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
7704 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
7705 generate just one large awk script for substitutions,
7706 eliminating much of the earlier complexity, while adding some
7707 new complexity. Only expand the substitution templates at
7708 configure time, for smaller configure script size. If
7709 _AC_SUBST_FILES are used, test 'awk' for working getline support
7710 at config.status time. If absent, interpolate through the
7711 shell. The awk script was written with much help
7712 from Paolo Bonzini and Paul Eggert.
7713 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
7714 (_AC_SED_FRAG_NUM): Likewise.
7715 (_AC_SUBST_CMDS): Renamed from...
7716 (_AC_SED_CMDS): ...this.
7717 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
7718 * tests/torture.at (Substitute a 2000-byte string): Also
7719 substitute a line with 1000 words, and a variable with several
7721 (Substitute and define special characters): Test awk special
7722 characters, and put substitution input strings `@foo@' in the
7723 output, to test that no recursion happens; test several other
7724 combinations from Paolo Bonzini.
7726 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
7728 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
7729 that replaced echo with AS_ECHO where this wasn't necessary.
7730 Problem reportd by Ralf Wildenhues.
7731 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
7732 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
7733 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
7735 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7737 * lib/freeze.mk (GREP): Removed, no need to initialize this.
7739 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
7741 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
7742 that traditional Awk lacks 3-arg "split". It has it.
7743 Mention that FS must be a single character, and a few other
7744 99-byte limits of traditional Awk.
7745 Mention that if (i in a) doesn't work with traditional Awk.
7747 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
7749 * tests/autotest.at (BSx641-newline in command):
7750 (BS-BS-newline in command, BSx640-newline in command):
7751 (Newline-CODE-BS-newline in command):
7752 (Single-quote-BS-newline in command):
7753 (Single-quote-newline-BS-newline in command):
7754 Use printf '%s\n' instead of echo, for portability to hosts
7755 where echo interprets backslashes. This will break on hosts
7756 that lack printf, but for now let's assume all such hosts
7757 are dead (if not, we should get reports of test failures).
7759 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
7761 'echo' has some portability problems, when given a first argument
7762 with a leading '-', or when given any argument containing '\'.
7763 Avoid using 'echo' in these cases.
7764 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

7767 * lib/autotest/general.m4 (AT_INIT): Likewise.
7768 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
7769 argument might be unportable.

7788 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
7789 * bin/autoconf.as: Redo verbose flag implementation, as the old
7790 scheme wouldn't work with AS_ECHO.
7791 * lib/autotest/general.m4 (AT_INIT): Likewise.
7792 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
7793 Don't use ECHO_T, since ECHO_N is now reliable.
7794 * lib/autotest/general.m4 (AT_INIT): Likewise.
7795 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
7796 rather than using a here-document to put the script into a file.
7797 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
7799 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
7800 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
7801 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
7802 bug, but we might as well stop using ECHO_N and ECHO_C internally.
7803 * lib/autotest/general.m4 (AT_SETUP): Likewise.

7805 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7806 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
7807 operand, as AS_ECHO requires. Avoid double file name expansion.
7808 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
7809 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
7810 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
7811 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
7812 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
7813 Double-quote strings that would otherwise contain M4 comments.
7814 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
7816 * configure.ac (AC_INIT): Bump to 2.61a.
7819 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
7823 * configure.ac (AC_INIT): Bump to 2.61.
7826 * tests/autotest.at (Macro with backslash in a test title):
7827 Comment out for now, as this tests neither fails nor passes
7828 reliably. Problem reported by Ralf Wildenhues.
7830 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
7832 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
7833 in previous change, which caused test failures.
7835 2006-11-16 Stepan Kasal <kasal@ucw.cz>
7837 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
7838 code for --enable, --disable, --with, and --without to...
7839 (_AC_INIT_PARSE_ENABLE): ... a new macro.

7845 Import these changes from config via gnulib:
7847 2006-11-15 Ben Elliston <bje@gnu.org>
7849 From Josselin Mouette <joss@debian.org>:

7915 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
7918 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
7920 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
7921 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.

7953 Single-quote in a test title,
7954 Double-quote in a test title): Don't expect failure anymore.
7955 (Backslash in a test title): Put a non-whitespace character after the
7956 backslash so that Bourne shells might actually see it as an escape

7965 Macro with double-quote in a test title,
7966 Macro with backslash in a test title): New tests expected to fail.
7967 * tests/torture.at (#define header templates): M4-quote this title in
7968 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
7969 The visible effect was a stray [] in the testsuite output.
7971 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7973 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
7974 `trap ... 0' inside a function, for AIX sh.
7976 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
7978 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
7979 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
7980 5363) simply issues a warning when dividing by zero at compile
7981 time. Problem reported by Elias Pipping.
7983 2006-10-26 Eric Blake <ebb9@byu.net>
7986 * doc/autoconf.texi (Evaluation Macros): Improve the example to
7987 show effect on macros that expand with commas.

8015 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
8016 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
8017 reported by Nelson H. F. Beebe for Coreutils 6.4.
8019 * tests/tools.at (autoconf --trace: user macros): Remove test
8020 for tracing multiline macros, since m4 1.4.7a uses a different

8049 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
8050 AC_CACHE_CHECK_INT, since it's no longer public.
8051 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
8052 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

8097 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
8099 (Imported from Automake.)
8100 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
8101 which incorrectly sets the mode of an existing destination
8102 directory. In some cases the unpatched install-sh could do the
8103 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
8104 system. We hope this is rare in practice, but it's clearly worth
8105 fixing. Problem reported by Alex Unleashed in
8106 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
8107 Also, don't bother to check for -m bugs unless we're using -m;
8108 suggested by Stepan Kasal.

8154 2006-10-13 Stepan Kasal <kasal@ucw.cz>
8156 * doc/autoconf.texi (Autoheader Macros): Warn that the text
8157 added to the template can get mangled.
8159 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8161 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
8162 include the default headers, and redefine obstack_chunk_alloc
8163 and obstack_chunk_free. Fixes false failure with glibc.

8182 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
8184 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
8185 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
8186 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
8187 Use a better substitute, by inspecting the output of "ls"
8188 rather than just using ":".
8189 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
8190 rather than AS_EXECUTABLE_P, since we needn't worry about
8191 non-regular files here.
8193 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
8194 due to configuration hassles with this. See Tonya Underwood's report
8195 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

8206 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
8207 initialization which is not inherited through the environment
8208 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
8209 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

8218 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
8219 comment about ac_cpp_err; it was incorrect, and anyway
8220 ac_cpp_err is being removed below.
8221 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
8222 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
8223 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
8225 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
8226 with werror_flag and conftest.err and so forth. This is more
8227 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
8228 and anyway the user shouldn't normally want to see this gorp logged.
8229 Problem reported by Ralf Wildenhues.
8230 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
8231 empty, not 'no', since the rest of the code uses 'test -z'.

8235 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
8236 Use a single call to AC_DO_TOKENS rather than multiple, for
8238 (_AC_LINK_IFELSE): Test that resulting file is executable.
8239 Problem reported by mwoehlke in
8240 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
8242 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
8243 than creating a file to use with test -x; this is much faster.
8245 2006-10-02 Bruno Haible <bruno@clisp.org>
8247 * lib/autom4te.in (Automake-preselections): Add
8248 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
8250 2006-09-27 Stepan Kasal <kasal@ucw.cz>
8252 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
8253 standard error, `experr' should be used, not `expout'.

8257 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

8259 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8260 Set cache var to 'unknown' (not 'no') if leaving the macro unset
8261 still doesn't let the program compile.
8262 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
8265 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
8266 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
8267 include it, without including anything else.
8268 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
8270 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

8276 Use a nonempty format string in the link test.
8277 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,

8449 except the first two arguments are reversed.
8450 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.

8498 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
8500 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
8501 didn't work if some values were cached but not others. Test for
8502 broken lex libraries like native ia64-hp-hpux11.22; see
8503 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
8504 work around the problem by preferring an empty LEXLIB to -lfl or
8505 -ll. Let the user set LEXLIB='' to indicate no library needed.

8657 problems with arg script text that doesn't end in newline, and

8735 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
8736 more globally, since the 2006-06-30 patch didn't suffice. Problem
8737 reported by Keith Marshall. Also, don't bother with builddir2,
8738 since it shouldn't be needed any more.
8740 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

8759 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
8761 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
8762 Require that long long int be at least 64 bits wide. C99 requires
8763 this and enough programs depend on it so we should check for it.
8764 Bruno Haible reports in

8777 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
8779 * doc/autoconf.texi: Be more consistent about using @acronym with
8780 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
8781 quite right (it talked about "OSF/Tru64", even though the
8782 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
8783 and it even mentioned "OSF 4"!) and at this point there's little
8784 reason to talk about OSF any more, since it died in 1994.
8785 (Specific Compiler Characteristics): Simplify example of
8786 negative-size array.
8787 (File Descriptors): Reorder to make the text flow better.
8788 Remove joke about "appreciate the various levels"; I didn't get it.

8790 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
8791 (File Descriptors, Limitations of Usual Tools):
8792 Tone down the advice against renaming or removing open files.
8793 (Limitations of Usual Tools): Add a new section, on 'rm'.
8795 2006-06-26 Stepan Kasal <kasal@ucw.cz>
8797 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
8798 -lXt in LIBS, idea from Karsten Hopp; this was due since
8801 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
8802 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
8803 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
8804 (which belong to Xt, not X itself). See Debian bug 327655.
8806 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8808 * configure.ac (AC_INIT): Bump to 2.60a.
8811 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8815 * configure.ac, NEWS: Update.
8817 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8819 * config/texinfo.tex: Sync from upstream.
8821 * bin/autom4te.in (handle_traces): Transform the `@S|@'
8822 quadrigraph correctly in traces.
8824 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
8827 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
8828 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
8830 * doc/autoconf.texi (Changed Directory Variables): New node,
8831 to document the whole `datarootdir' business a bit better.
8833 * tests/torture.at (datarootdir workaround): Extend test.
8834 Prompted by report by Alexandre Julliard.
8836 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
8838 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
8839 when using default mode of IBM C 6 for AIX. Problem and two-line
8840 fix reported by Larry Jones.
8842 2006-06-22 Alexandre Julliard <julliard@winehq.org>
8844 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
8845 about literal '${datarootdir}' if a definition is found in the
8848 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
8850 * NEWS: Use "M4" rather than "m4" when appropriate.
8851 Problem reported by Eric Blake.
8852 * doc/autoconf.texi: Likewise.
8853 Use @acronym around BSD, GCC, and GNU when appropriate.
8854 (Why GNU M4): Renamed from "Why GNU m4".
8855 (Redefined M4 Macros): Mention that Posix
8856 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
8857 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
8860 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8862 * bin/autom4te.in (handle_output): Do not forbid the empty
8864 * tests/tools.at (autoconf: the empty token): New test.
8866 2006-06-20 Stepan Kasal <kasal@ucw.cz>
8868 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
8869 calls, so that we do not care whether they are LIFO or FIFO;
8870 in the m4_wrap, do not check which diversion is the topmost
8871 one, just check that the stack is balanced at the end.
8872 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
8873 base diversion forever--pop the previous diversion before
8874 opening the new one; consequently, remove the m4_wrap call.
8875 * lib/autotest/general.m4 (AT_INIT): Likewise.
8876 * tests/m4sugar.at: Do not use
8877 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
8879 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
8880 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8882 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
8883 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
8884 Rework example of m4wrap token-pasting trouble so that it doesn't
8885 care whether it's LIFO or FIFO.
8886 Fix some "contrary to"s that are awkward in English.
8888 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8890 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
8891 to `yes' instead of `int$1_t' if the type is found, for more
8892 consistent configure output (where $1 is the number of bits).
8893 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
8894 Suggested by Bruno Haible.
8896 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
8897 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
8898 with system headers. Report by Bruno Haible.
8900 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8902 * config/config.guess, config/config.sub: Sync from upstream.
8904 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
8905 in order to avoid picking up an older installed frozen m4sh.m4f.
8906 Besides an outdated shell startup, this could have been created
8907 by an earlier M4 version with incompatible frozen file format.
8909 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
8911 * README: Recommend m4 1.4.4 instead of 1.4.3..
8912 * doc/autoconf.texi: Likewise.
8913 (Special Chars in Names): Say that $(.FOO) is portable, as
8914 suggested by Stepan Kasal.
8915 (Installation Directory Variables, Build Directories):
8916 (Automatic Remaking, Subdirectories, Fortran Compiler):
8917 (Making testsuite Scripts, Defining Directories):
8918 Quote variable usages better.
8919 (Making testsuite Scripts): Add clean-local rule to makefile
8920 snippet, by Eric Blake.
8921 (Installation Directory Variables): Fix table item font.
8922 Reword slightly to clarify. Generalize advice about
8923 not using special characters to include all file-related
8924 vars, not just VPATH.
8925 (Special Chars in Variables): Warn about special characters in
8927 (Assignments): Clarify default-value example as suggested by
8929 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
8930 (Special Shell Variables): Note leading ./ or ../, as suggested
8932 (Limitations of Builtins): Under cd, warn about CDPATH.
8933 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
8936 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8938 * doc/autoconf.texi (Configuration Actions): Remove duplicate
8939 `@var', for texi2html.
8940 (Systemology): Some more word wrapping, for DVI output.
8941 (autom4te Invocation): The short option for `--melt' is `-M',
8944 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
8946 * doc/autoconf.texi: More formatting and English tweaks,
8947 many suggested by Ralf Wildenhues.
8948 Reword to avoid "@code{...}'s" and the like, since it's ugly
8949 with Emacs info mode. discontents -> woes.
8950 Put a few "will"s back. time stamp -> timestamp.
8951 side-effect -> side effect.
8953 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
8955 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
8956 Warn about $@ not persisting. Problem reported by Julien Danjou in
8957 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
8958 (Special Chars in Names): Renamed from Leading _ in Macro Names.
8959 Mention other special chars, too.
8961 2006-06-14 Eric Blake <ebb9@byu.net>
8963 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
8965 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
8967 * doc/autoconf.texi: Some systematic minor improvements, as
8968 follows. Use "makefile" when talking about makefiles
8969 generally (which might be named "makefile" or "Makefile" or even
8970 "foo.mk"), "Makefile" when talking about a specific makefile
8971 called "Makefile". This unclutters the text from weird quotes
8972 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
8973 values" rather than "@var{foo}s" and similar constructs containing
8974 "}s". Use "Make rules" rather than "Makefile rules". Minor
8975 English-language improvements. Change the prefix "sub-" to "sub"
8977 Put blank lines around examples more consistently.
8978 Avoid "rather" and "very" as intensifiers.
8979 Avoid "will" as an auxiliary.
8980 (Limitations of Make): Split this node into....
8981 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
8982 (Leading _ in Macro Names, Backslash-Newline-Newline):
8983 (Backslash-Newline Comments, Long Lines in Makefiles):
8984 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
8985 (obj/ and Make, make -k Status, VPATH and Make):
8986 (VPATH and Double-colon, $< in Explicit Rules):
8987 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
8988 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
8989 New nodes, resulting from splitup of Limitations of Make.
8990 All cross-references changed. Raise the top node from
8991 a section to a chapter, and all subnodes accordingly.
8992 Redo the introductory wording to match the new organization.
8993 (Installation Directory Variables): Use an example that is
8994 closer to what Autoconf actually does. Mention that VPATH's
8995 value should not contain metacharacters or white space.
8996 (Fortran Compiler): Fix a VPATH bug in an example.
8997 (Leading _ in Macro Names): Mention that this problem is no longer
8998 of practical concern.
8999 (VPATH and Make): Reword the advice to make it clearer
9000 that Autoconf and Automake support VPATH in non-GNU make, but
9001 many packages have bugs in this area.
9002 ($< in Explicit Rules): Refer to Build Directories rather
9003 than using a (non-VPATH-safe) example.
9004 (Automatic Rule Rewriting): Mention the sort of disaster that
9005 can ensue with Solaris-style rule rewriting with VPATH.
9007 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9009 * doc/install.texi (Compilers and Options): Weaken the
9010 suggestion to use GNU make for VPATH builds.
9012 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
9013 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
9015 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
9016 in regular expression.
9018 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9020 * doc/autoconf.texi (Installation Directory Variables):
9021 Drop extra @samp from `@table @samp' item.
9022 (Limitations of Usual Tools): Comment fix.
9023 Do not nest @samp just to point to other table items.
9024 (Writing testsuite.at) <AT_CHECK>: The second argument to
9025 `@dvar' is already @samp'ed.
9026 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
9027 do not use @var in the second argument.
9029 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
9031 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
9032 $as_shell.exe too. Problem reported by Andreas Buening in
9033 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
9035 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9037 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
9038 `unused variable' compiler warning, for `-Wall -Werror'.
9039 Reported by Jaap Haitsma in
9040 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
9042 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
9044 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
9045 case the compiler dumps core. Problem reported for
9046 OpenServer 5.0.7 by Tim Rice in
9047 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
9048 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9051 2006-06-06 Tim Rice <tim@multitalents.net>.
9053 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
9054 "ERROR" only shows up in "make check" output if there is an
9057 2006-06-06 Eric Blake <ebb9@byu.net>
9059 * tests/tools.at (automatically allowed tokens): Fix typo.
9061 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9063 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
9065 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
9066 typically overflows on x86 CPUs, even though the C standard
9069 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9071 * configure.ac (AC_INIT): Bump to 2.59e.

9078 * config/texinfo.tex: Sync from upstream.
9080 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
9081 seen, invoke libtoolize with `--ltdl' argument.
9082 * lib/autom4te.in (Autoreconf-preselections): Adjust.
9084 Suggested by Eric Blake.
9086 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9088 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
9089 reported by Ralf Wildenhues.

9103 message issued by AC_REQUIRE.
9104 * tests/m4sugar.at: Check m4_require's error message.
9105 * tests/base.at: Check AC_REQUIRE's error message.
9106 * tests/local.at (AT_CHECK_M4): New macro, almost identical
9108 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
9110 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
9111 `expout' as the last parameter.
9112 * tests/tools.at: Adapt to the above change.
9114 2006-06-04 Stepan Kasal <kasal@ucw.cz>
9116 * doc/autoconf.texi (Limitations of Usual Tools): Correct
9117 information about race-free implementations of mkdir.

9126 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
9128 * NEWS: GNU make now recommended for VPATH builds.
9129 Mention that some macros are now documented to be obsolescent.
9130 * doc/autoconf.texi:
9131 Prefer "current" to "modern" to describe
9132 currently-used (albeit perhaps old-fashioned) hosts.
9133 Mention which ancient features no longer need to be worried about.
9134 setgid -> set-group-ID
9135 setuid -> set-user-ID (these are the Posix terms)
9136 Fix some misuses of "only".
9137 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
9138 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):

9151 Omit longwinded and obsolescent discussion of cp -f.
9152 Modernize discussion of expr, ls.
9153 (Limitations of Make): Modernize discussion of VPATH builds.
9154 Mention $? as a workaround in some cases.
9155 * doc/install.texi (Basic Installation):
9156 Mention "./configure; make; make install" first. Be more
9157 specific about why this file is generic. Remove unnecessary
9158 parens. Remove misleading "only". Remove obsolete advice
9159 about csh. Don't say "configure" takes awhile; say it
9160 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
9161 and CC=c99 rather than CC=c89, as these are blessed by current
9162 Posix. Recommend GNU make if doing a VPATH build.
9164 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
9166 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
9167 examples involving shell prompts.

9170 and Paul Eggert <eggert@cs.ucla.edu>
9172 * doc/autoconf.texi (Here-Documents): Add details about the
9173 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
9174 use "here-documents" instead of "here documents".

9183 anywhere in directory names.
9185 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
9187 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
9188 about quoting the case statement, just in case.

9206 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9208 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
9209 about quoting ac_try: quote all of it, if any of it seems suspicious.
9210 This means we don't have to worry about ${ or sed any more.
9211 Also, double-quote the case statement, to work around misuses via
9212 underquoting as reported by Ralf Wildenhues in
9213 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
9214 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
9215 undocumented and dangerous macro.
9216 Problem reported by Ralf Wildenhues in

9225 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9227 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
9228 since evidently some packages rely on the old, broken behavior.
9229 Problem reported by Ralf Wildenhues in
9230 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
9231 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
9232 pre-2006-05-26 definitions, but leave in the comments that
9233 these macros are dangerous and should not be used.
9234 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
9235 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
9236 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
9237 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
9238 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
9240 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
9242 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
9243 the use of 'tr', since this is our only use of 'tr'.
9245 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9246 and Paul Eggert <eggert@cs.ucla.edu>
9248 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
9249 Don't assume 'grep' works on long lines, since AIX grep doesn't.
9251 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9253 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
9254 the output file in the `${datarootdir}' test.
9256 2005-05-28 Stepan Kasal <kasal@ucw.cz>
9257 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9259 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
9260 mention of `datarootdir' in the input file(s), but literal
9261 `${datarootdir}' in the output file, and we haven't warned yet,
9262 then warn as well: the user may have (erroneously) used
9263 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
9264 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
9265 * tests/torture.at (datarootdir workaround): Extend this test.
9268 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9269 and Paul Eggert <eggert@cs.ucla.edu>
9271 * doc/autoconf.texi (autoheader Invocation): The first argument to
9272 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
9273 alternatives and clear up the language a bit.
9275 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
9277 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
9278 ac_config_guess, ac_config_sub, ac_configure.
9279 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9280 Fix typo that prevented an unnecessary space from being removed.
9281 Problems reported by Ralf Wildenhues in:
9282 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
9284 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
9286 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
9287 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
9288 Don't use the term "thread-safe" to talk about mkdir race
9289 conditions, since the problem is more a process than a thread
9290 issue. Problem reported by Stepan Kasal in:
9291 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
9292 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
9293 the test for 'install' more closely. Look at MKDIR_P first.
9294 Look in the PATH, and at /opt/sfw/bin.
9295 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
9296 Don't bother to try mkdir -p, since we already check mkdir --version;
9297 just look at the version number. (There's no easy way to check
9298 for race-free implementations.)
9299 * tests/tools.at (autoconf: subdirectories): Adjust to above
9300 changes, since MKDIR_P now might end in "/mkdir -p".
9302 * doc/autoconf.texi (autoheader Invocation): Mention that the
9303 first arg of AC_DEFINE_UNQUOTED must be a literal.
9304 Problem reported by Ben Pfaff in
9305 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
9307 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
9308 * doc/autoconf.texi (Special Chars in Variables): New section.
9309 (Preset Output Variables): Warn about special chars in CPPFLAGS.
9310 (Installation Directory Variables): Quote $(datadir) better.
9311 (Limitations of Builtins): Describe some of eval's trickiness.
9313 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
9314 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
9315 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
9316 in front of every arg, not just trailing args. Quote apostrophes.
9317 (_AC_EVAL_ECHO): New macro.
9318 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
9319 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
9321 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
9322 exposed by quoting of eval argument. Put the command on line line
9324 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
9325 (_AC_PATH_X, AC_PATH_X): Quote more safely.
9326 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
9327 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
9328 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
9329 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
9330 Use eval more safely.
9331 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
9332 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
9334 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
9335 lines, exposed by quoting of eval argument.
9337 2006-05-26 Stepan Kasal <kasal@ucw.cz>
9338 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9340 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
9341 initialization of `ac_cv_exeext', do not override it if it was
9342 already set, unless it was set to `no', for compatibility with
9343 Autoconf-2.13, and comment this.
9344 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
9345 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
9346 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
9347 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
9348 Document that this test may be overridden by setting
9351 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9353 Revert these two patches:
9355 2006-04-06 Eric Blake <ebb9@byu.net>
9356 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
9357 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
9360 2006-04-01 Stepan Kasal <kasal@ucw.cz>
9361 Clean up _AC_COMPILER_EXEEXT* macros.
9362 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
9363 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
9364 ac_file to the name of the default output file and call
9365 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
9366 initial `rm' of the candidate files...
9367 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
9368 the same list in subsequent `rm' calls, and for the temporary
9369 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
9370 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
9371 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
9372 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
9373 no longer needed) by libtool. Make it a cache check.
9374 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
9375 copied here by mistake.
9376 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
9377 _AC_COMPILER_EXEEXT.
9378 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
9379 _AC_COMPILER_OBJEXT directly.
9380 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
9382 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9384 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
9385 Fix description of how the buggy `sed' works.
9387 2006-05-25 Noah Misch <noah@cs.caltech.edu>
9391 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
9392 ENOLCK. Only mention `make -j' when applicable. Only raise
9393 fatal errors when `make -j' is involved. Improve error message.
9395 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9397 * doc/autoconf.texi (Here-Documents): We now know more about
9398 the variable expansion in here documents bug.
9399 Thanks to Tim Rice and Stepan Kasal.
9401 * doc/autoconf.texi (Making testsuite Scripts): Add an example
9402 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
9404 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9406 * tests/autotest.at (Multiline command from M4 expansion):
9407 No failure to be expected if the shell quotes newlines in
9408 commands in the `set -x' output. Report by Tim Rice.
9411 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9413 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
9414 expansion in the here-documents used by config.status, as that
9415 runs afoul of the Korn shell version M-12/28/93d bug described in
9416 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
9417 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
9418 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
9420 2006-05-23 Jim Meyering <jim@meyering.net>
9422 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
9423 Fix typo introduced with 2006-04-02 change. It reversed the sense
9426 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9428 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
9429 ac_dB slightly, to save bytes in the script.
9430 Max out at 50 lines, rather than 96; this is more likely
9431 (though not guaranteed) to avoid obscure 'sed' failures.
9433 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9435 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
9436 `tr -d -' as bad option argument. Work around this by deleting
9437 an unrelated character.
9438 Report by Tim Rice <tim@multitalents.net>.
9440 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
9441 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
9442 Stepan Kasal <kasal@ucw.cz>
9444 * doc/autoconf.texi (Particular Programs): Do not promise that
9445 we always prefer the GNU version of the program, and that we
9446 search according to PATH; both rules can have exceptions.
9447 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
9448 AC_PROG_SED. Move descriptions of limitations
9449 to the Limitations of Usual Tools section.
9450 (Limitations of Usual Tools) <sed>: Mention script length
9451 limitations with Solaris /usr/ucb/sed.
9452 <grep>: Fix wording for empty alternative. Mention that -c and
9453 -l should not be combined, and that -E and -F should not be
9456 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9457 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9459 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
9460 limits in Solaris 8 /usr/ucb/sed by testing a long script.
9462 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9464 * doc/autoconf.texi (Defining Symbols): Literal parameter of
9465 AC_DEFINE is now passed to m4_pattern_allow.
9466 * NEWS: Mention that; likewise for AC_SUBST.
9467 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
9468 the parameter to m4_pattern_allow.
9469 * tests/tools.at: Add a check for that.
9471 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9473 * lib/autoconf/status.m4: Fix typos.
9475 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9477 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
9478 only the files that this macro generates.
9480 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9482 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
9483 the HP-UX sed limitation of 99 commands, labels do not count.
9484 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
9486 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
9488 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9490 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9491 Import the following fix from coreutils:
9493 2006-01-13 Jim Meyering <jim@meyering.net>
9495 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
9496 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
9497 not double-quote uses of that variable, to accommodate the rare
9498 case in which getmntent is available in none of the libraries
9499 checked. This happens at least on FreeBSD 5.0.
9501 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
9503 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
9504 ac_config_guess, ac_config_sub, and ac_configure, since evidently
9505 some other programs unwisely rely on these undocumented vars.
9506 But put in warning comments about them.
9507 Problem reported by Ralf Wildenhues in
9508 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
9509 * NEWS: Document that these variables are intended to go away.
9511 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9513 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
9514 and set the language to C++ (analogous to the equivalent Fortran
9517 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
9518 * doc/autoconf.texi (C++ Compiler): Document it.
9519 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
9522 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
9524 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
9525 that caused config.status to generate 100-command sed scripts; the
9526 portable limit is 99.
9528 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9530 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
9531 variable `ac_d' instead of `d' to avoid infringing namespace.
9532 Report by Ralf Menzel.
9534 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
9536 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
9537 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
9538 * tests/tools.at (autoconf: subdirectories): New test, taken from
9539 the corresponding problem report by Ralf Wildenhues in:
9540 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
9542 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
9543 Quote some uses of shell variables if they might suffer unexpected
9544 globbing. This doesn't fix all instances of quoting problems that
9545 I found, just the easy ones that look safe.
9546 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
9547 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
9548 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
9549 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
9550 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
9551 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
9552 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
9554 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
9555 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
9557 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9559 * bin/autoreconf.in ($help): Reword according to the manual.
9560 Suggested by Olly Betts.
9562 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
9563 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9565 * bin/autoreconf.in: Pass the directory argument to
9566 `require_configure_ac'. Fix comment.
9567 * tests/torture.at (Configuring subdirectories): Expose this.
9568 Reported by Olly Betts.
9570 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9572 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
9573 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
9574 Automake as follows:
9576 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
9577 `$configure_in' instead of `configure.in', to preserve
9578 directory component.
9580 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9582 * config/config.guess, config/config.sub, config/texinfo.tex,
9583 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
9585 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
9587 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
9588 test for C99 conformance; (bool) 0.5 is an integer constant
9589 expression, but (bool) -0.5 is not. Problem reported by Fedor
9590 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
9592 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
9594 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
9595 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
9596 Warn about obsolete install-sh files. Remove stray sentence
9597 fragment and fix cross reference.
9598 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
9599 install -d; this undoes the 2006-05-10 change.
9600 (MKDIR_P): Mark with AN_MAKEVAR.
9601 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
9602 that we don't require $INSTALL to be thread-safe. Move comments
9603 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
9604 of AC_PROG_INSTALL. Output a message saying that we're checking
9605 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
9606 MKDIR_P instead of AC_SUBST.
9607 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
9608 Special magic for MKDIR_P, too.
9609 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
9611 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
9613 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
9615 Sync from Automake, as follows:
9617 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9618 * config/install-sh: Initialize IFS, so field splitting isn't
9620 * config/mkinstalldirs: Likewise.
9621 * config/missing: Remove superfluous quotes. Replace all uses of
9622 `[' by `test', for consistency, and for..
9623 * config/missing (sed_minuso, sed_output): New variables.
9624 (autom4te, help2man, makeinfo): Use them. Unifies detection of
9625 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
9626 Fixes `missing' to detect `--output' for help2man. Fixes
9627 PR automake/483. Report by Dennis J. Linse.
9628 (autom4te): Document in `missing --help'.
9630 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9632 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
9633 * config/install-sh: Don't use 'path' to talk about file names,
9634 as per GNU coding standards. Close a race condition reported by Ralf
9635 Wildenhues and Stepan Kasal. There is still a race condition
9636 on hosts that predate Posix 1003.1-1992, but we can't help this.
9637 Don't mishandle weird characters like space on pre-Posix hosts.
9638 Invoke mkdir at most once per dir arg on pre-Posix hosts.
9639 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
9640 AC_PROG_MKDIR_P from AS_MKDIR_P.
9641 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
9642 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
9643 earlier editions are not (including Automake 1.8.3).
9644 Do not suggest mkinstalldirs for thread-safety.
9645 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
9646 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
9647 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
9648 presence of special characters and race conditions.
9649 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
9650 in Autoconf's name space.
9652 2006-05-10 Bruno Haible <bruno@clisp.org>
9653 and Paul Eggert <eggert@cs.ucla.edu>
9655 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
9656 from Automake with minor changes.
9657 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
9659 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9661 * config/install-sh: Update to Automake CVS version, as follows:
9662 2006-04-25 Stepan Kasal <kasal@ucw.cz>
9663 * lib/install-sh: Simplify the expr implementation of dirname.
9664 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
9665 * lib/install-sh: Handle --, and diagnose unknown options.
9667 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9669 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
9670 `./autom4te' to create `./testsuite', since the `all' target
9671 will ensure its presence, but `installcheck' should not create
9672 the uninstalled wrappers.
9674 * tests/torture.at (Unusual Automake input files): Skip if we
9675 detect automake < 1.8.
9677 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9679 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
9680 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
9681 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
9684 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9686 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
9687 munge (multiple) white space and other oddities.
9688 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
9689 single quotes in variable assignment.
9690 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
9691 and similar failures by adding multiple spaces, tabs, and other
9693 Report and different test suggested by Francesco Romani
9694 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
9696 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
9697 single quotes, we only need to search for single quotes; this
9698 both simplifies the search pattern, and makes us less
9699 susceptible to `echo' variations for arguments not containing
9701 (_AC_ARG_VAR_VALIDATE): Likewise.
9703 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9729 traditional shells like the Solaris one that do not use the
9730 first IFS character for assembling `$*'.
9731 Prompted by a related report from autoconf_bug@nro.ca.
9733 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>

9783 (Portable Shell): Mention the Posix shell.
9785 2006-04-25 Stepan Kasal <kasal@ucw.cz>
9787 * bin/autoconf.as (me): Replace by as_me.
9789 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
9791 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
9792 since as_me isn't set yet.
9794 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
9796 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
9797 a few minor bugs in this area.
9799 * doc/autoconf.texi (Programming in M4sh): Comment out the
9800 documentation of AS_BASENAME, for now.
9801 (Shell Substitutions): Do not use AS_DIRNAME in an example.
9802 (Limitations of Builtins) <basename>: Do not refer to
9804 * bin/autoconf.as (me): Don't use AS_BASENAME.
9805 (dir): Remove the unused variable.
9806 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from

9815 (_AS_DIRNAME_PREPARE): Likewise.
9816 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
9817 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.

9820 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
9822 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
9823 of "run time" and "run-time" changed to "runtime", for consistency.

9827 * lib/autoconf/headers.m4: Likewise.
9829 * doc/autoconf.texi (Run Time): Document the exit status situation
9830 with more accuracy and detail.
9832 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9834 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
9835 Archive is not officially `GNU' any more. Update URL.
9836 (Defining Directories): Likewise
9837 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
9839 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9841 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
9842 newline from the `trap' code to finish `config.log'; the NetBSD
9843 /bin/sh resets the exit status after an empty command, as
9844 documented in doc/autoconf.texi.
9845 Reported by Dalibor Topic <robilad@kaffe.org>.
9847 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
9849 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
9850 Suggested by Bruno Haible.
9852 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
9854 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
9855 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
9856 Instead, just list the shells that we know work.
9857 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
9858 changed. Be more cautious about the _cv_ variable.
9859 * tests/tools.at (Syntax of the shell scripts): Check the
9860 _cv_ variable once, at first, to avoid an internal autoconf error
9861 when sh -n does not work.
9863 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9865 * lib/Autom4te/FileUtils.pm: Sync from Automake.
9867 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
9869 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
9870 use ">&-" since we're only 99.999% sure that this is portable,
9871 and since the MinGW bug is fixed in a different way.
9872 * lib/autotest/general.m4 (AT_INIT): Likewise.
9874 2006-04-16 Stepan Kasal <kasal@ucw.cz>
9876 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
9877 before opening config.log, to avoid hitting a bug on MinGW.
9879 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
9881 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
9882 AS_MESSAGE_LOG_FD before reopening it onto the log file.
9883 This works around a MinGW bug reported by Eric Paire.
9884 Make sure that all writes to the log file append to it,
9885 rather than possibly losing data.
9886 * lib/autotest/general.m4 (AT_INIT): Likewise.
9888 2006-04-14 Stepan Kasal <kasal@ucw.cz>
9890 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
9893 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9897 * configure.ac (AC_INIT): Bump to 2.59d.
9899 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9903 * Makefile.maint (news-date-check): Do not require a leading `*'
9904 before the release date in NEWS.
9906 2006-04-12 Stepan Kasal <kasal@ucw.cz>
9907 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9909 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
9910 the instantiated file do not contain the string 'datarootdir'
9911 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
9912 @mandir@, replace the reference '${datarootdir}' by the value.
9913 * tests/torture.at (datarootdir workaround): New test.
9914 * NEWS: Advertise this temporary fixup.
9915 Based on a patch by Bruno Haible, reported and analyzed by
9916 Paul Eggert and Noah Misch.
9918 2006-04-12 Eric Blake <ebb9@byu.net>
9920 * tests/autotest.at (Debugging a failed test): Fix comment.
9922 2006-04-12 Stepan Kasal <kasal@ucw.cz>
9924 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
9925 all the changes since 2006-04-07.
9927 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9929 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
9930 succeeded, but `ln -s file dir' failed, take care to remove the
9931 leftover target before the next test, to prevent its spurious
9932 failure; also make sure `ln file dir' works before selecting it.
9933 Thanks to Keith Marshall for pointing this out.
9936 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
9937 assignments in `at_debug_args', so that we put them correctly
9938 in the `run' script.
9939 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
9940 Reported by Eric Blake.
9942 2006-04-11 Eric Blake <ebb9@byu.net>
9944 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
9945 top-level tests after micro-suite has been run. Used in...
9946 (Debugging a successful test, Debugging script and environment),
9947 (Debugging a failed test): ...these new tests. The first of these
9949 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
9950 macro, split out from...
9951 (AT_INIT): ...here, so that using -d also generates a run script.
9952 Document that -d inhibits top-level logging.
9953 * doc/autoconf.texi (testsuite Invocation): Document that -d only
9954 inhibits top-level logging; debug scripts are created.
9956 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
9958 * tests/autotest.at (Empty test, Empty check): New test to check it.
9960 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
9963 2006-04-10 Stepan Kasal <kasal@ucw.cz>
9965 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
9966 the files if a problem appears. Make the empty *.at files
9967 read-only, too. Proposed by Ralf Wildenhues.
9969 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9971 * config/Makefile.am: Add comment to force updated Makefile.in.
9973 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
9974 space only patch to this file, this patch causes the Makefile.in
9975 files that include freeze.mk to be updated, and thus have a
9976 newer time stamp again, which in turn makes a pristine CVS
9977 checkout have correct time stamps.
9979 * Makefile.maint (cvs-sv): New macro, to be used..
9980 (config.guess-url_prefix, config.sub-url_prefix)
9981 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
9982 point to CVS text checkout of Gnulib files.
9983 (copyright-check): Bump current year.
9984 (announcement): Do not hard-wire `./announce-gen'.
9985 (cvs-update): Propagate failures of `cvs' and `move-if-change'
9987 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
9989 (wget_files): Update config.guess, config.sub, texinfo.tex by
9990 `wget-update', now that their URLs work again.
9992 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
9994 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
9995 Problem noted by Paul D. Smith.
9997 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9999 * doc/autoconf.texi: Remove unused words from word list.
10000 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
10001 .x-sc_trailing_space: New files.
10003 * doc/standards.texi: Sync from gnulib.
10005 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
10006 `LIBOBJDIR' as experimental.
10008 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
10009 with a target directory; it's internally implemented as `cp'
10010 anyway, but since Autoconf advertises the possibility to use
10011 a target directory when LN_S is `ln -s', we need to find out.
10012 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
10013 analyzed by Keith Marshall <keith.marshall@total.com>.
10017 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10019 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
10020 confdefs.h as-is. In general, if it has backslash-newline or the
10021 like, then it doesn't work either to sort or to remove empty
10024 2006-04-09 Stepan Kasal <kasal@ucw.cz>
10026 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
10028 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
10030 * lib/autom4te.in (Automake-preselections): Preselect
10033 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10035 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
10036 apostrophe within a single-quoted string, as this is the usual
10037 tradition and is easier to read than '"'"'. Don't rely on the
10038 shell treating "$/" like '$/'. Use a more-consistent indenting
10039 style for the trap.
10041 2006-04-09 Eric Blake <ebb9@byu.net>
10043 * tests/autotest.at (Backquote command substitution),
10044 (Multiline backquote command substitution): Remove mistaken
10045 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
10047 (Parenthetical command substitution, Multiline parenthetical
10048 command substitution): here.
10050 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

10075 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

10080 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
10081 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
10082 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
10083 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
10084 (C Compiler): Move AC_C_LONG_DOUBLE to ...
10085 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
10086 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
10087 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
10088 (Coding Style). Don't mention m4_expand_once.

10097 (AC_HEADER_ASSERT): New macro.
10098 (AC_HEADER_STDBOOL): Don't assume "#error" works.
10099 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.

10114 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
10115 of the warning introduced by the 2001-08-28 change.
10117 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
10118 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10120 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
10121 variables shall be overriden by the cache.
10122 * tests/torture.at (AC_ARG_VAR): Test also with a first value
10123 that contains braces.
10125 2006-04-07 Stepan Kasal <kasal@ucw.cz>
10127 Revert the patch from 2006-04-01 and only improve
10128 _AS_DETECT_BETTER_SHELL:
10130 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
10131 skip nonexistent directories.
10132 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
10133 only shell candidates which exist.
10134 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
10135 * lib/autotest/general.m4 (AT_INIT): No need to give three
10136 parameters to _AS_PATH_WALK.

10183 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
10184 whether `set' quotes correctly: redirect stderr of the tested
10185 `set', and use a subshell, for Ultrix; use `sed' instead of
10186 `grep' for zsh `set' which may write binary output; match only
10187 at the beginning of a line, to avoid false positives.
10188 In order to avoid false positives by unrelated variables with
10189 multiline content, put the dump algorithm in a subshell and
10190 unset all variables containing newlines (except some which are
10191 special to the shell). Warn about cache variables that are

10199 * tests/mktests.sh: Reword comments.
10201 * tests/mktests.sh: Only skip internal macros starting with
10202 `_AC_' or `__AC_'. Noted by Stepan Kasal.
10203 Update exclusion lists for the test suite to this end:
10204 (AC_ARG_VAR): Do test this now.

10238 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
10239 (AC_CONFIG_COMMANDS): Do not do so here.
10240 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
10241 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
10242 2005-07-25 rewrite. Noticed by Noah Misch.

10248 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once

10296 normalizing it, consistent it with previous releases.
10297 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.

10307 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
10308 Use 'comm' rather than N instances of grep; this also fixes a bug
10309 whereby substrings were incorrectly matched, causing us to not
10310 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
10311 (exclude_list): Exclude empty macros.

10399 initial `rm' of the candidate files...
10400 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10401 the same list in subsequent `rm' calls, and for the temporary
10402 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,

10404 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10405 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10406 no longer needed) by libtool. Make it a cache check.
10407 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10408 copied here by mistake.

10538 checked for existence, so we don't barf over a nonexisting
10539 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
10541 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

11103 CONFIG_SHELL in the environment of the configure rerun.
11104 * doc/autoconf.texi (Here-Documents, config.status Invocation):
11105 Suggest passing CONFIG_SHELL absolute, and in the environment
11106 rather than as option.

11126 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
11127 Factor functionality to..
11128 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
11129 `AC_SUBST($1)' in the public version.
11130 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
11131 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

11151 conftst2.$ac_objext.
11152 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
11154 2005-10-24 Stepan Kasal <kasal@ucw.cz>
11156 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
11157 conftest.o, to see whether the compiler really obeys; rm the object
11158 file before and after the test and register it with ac_clean_files.

11181 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
11182 AC_LANG_PROGRAM, fixing a typo. Don't give details about
11183 the inner workings of AC_LANG_FUNC_LINK_TRY.
11184 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
11185 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
11186 by the function rather than ignoring it.
11187 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
11188 comparing its address. Intel's interprocedural optimization was
11189 outsmarting the old heuristic. Problem reported by
11192 2005-10-19 Stepan Kasal <kasal@ucw.cz>
11194 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

11201 2005-10-04 Stepan Kasal <kasal@ucw.cz>
11203 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
11204 before removing it (chmod -R u+rwx); there are three instances of this.
11206 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11207 Stepan Kasal <kasal@ucw.cz>
11209 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
11210 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
11211 make its content writable before removing it. Remove an errorneous
11212 comment from the end, where the logs of the failed tests are copied
11213 to the main log file.
11215 2005-09-27 Stepan Kasal <kasal@ucw.cz>
11217 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
11218 in case the computer is too quick. Double quote the configure.ac
11221 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
11222 problems if the testsuite were running too fast.
11224 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
11226 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
11227 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
11228 (which belong to Xt, not X itself). See Debian bug 327655.
11229 * NEWS: Mention this.
11231 2005-09-07 Stepan Kasal <kasal@ucw.cz>
11233 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
11235 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
11237 * config/move-if-change: Don't output "$2 is unchanged";
11238 suggested by Ben Elliston. Handle weird characters correctly.
11240 2005-09-06 Stepan Kasal <kasal@ucw.cz>
11242 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
11243 calls, so that the final expansion of this macro is shorter.
11244 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
11245 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
11246 the cleanup there. Use AS_VAR_* macros, to be more general.
11247 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
11249 * lib/autoconf/general.m4: Use AS_IF where appropriate.
11251 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
11253 2005-09-01 Stepan Kasal <kasal@ucw.cz>
11255 * doc/autoconf.texi (Configuration Headers): Add an index entry
11258 2005-08-26 Pavel Roskin <proski@gnu.org>
11260 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable

11264 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
11266 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
11267 The previous patch didn't work, so try a better one.
11269 2005-08-26 Stepan Kasal <kasal@ucw.cz>
11271 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
11272 in the example. Reported by Bruno Haible.
11273 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
11274 "if $undefined_var;" succeeds with my shell.
11276 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
11277 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
11278 but change the m4_divert_text to m4_divert_once.
11280 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
11282 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
11283 Work around bug in Solaris /usr/xpg4/bin/awk.
11284 The bug is present in at least Solaris 8 through 10.
11286 2005-08-24 Stepan Kasal <kasal@ucw.cz>
11288 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
11289 some evil values and relying on the fact that $* concatenates the
11290 parameters by the first character from IFS.
11292 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
11293 Stepan Kasal <kasal@ucw.cz>
11295 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
11296 first header appears, define AH_HEADER.
11297 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
11298 Update limitations about when to call AC_CONFIG_HEADERS.
11299 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
11300 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
11301 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
11302 ``Configuration Actions''; fix their index entries.
11304 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
11305 options correctly. Process N-M as M-N if M is smaller than N.
11306 Process ranges correctly so that N-N will run only N.
11307 Sort and uniquify the tests that will be run. If there is more
11308 than one test, reinsert the banners for the tests.
11309 * tests/autotest.at (Keywords): Unmark XFAIL.
11311 2005-08-23 Stepan Kasal <kasal@ucw.cz>
11313 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
11314 before passing the macro name to AH_TEMPLATE.
11316 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
11317 now opens log after option processing; in particular, --version
11318 and --help do not touch config.log.
11320 * Makefile.maint: Revert the change from 2005-08-12.
11322 2005-08-22 Stepan Kasal <kasal@ucw.cz>
11324 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out

11330 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
11331 (Autotest Logs, Writing testsuite.at, testsuite Invocation):

11335 Prepend to LIBS, not append, in examples.
11337 2005-08-16 Stepan Kasal <kasal@ucw.cz>
11339 When building in place, set srcdir="."; suggested by Tim Van Holder.
11341 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
11342 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
11343 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
11344 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
11345 does not mean "no --srcdir option".
11347 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11349 * tests/autoscan.at (autoscan): New file.
11350 * tests/suite.at: Use it.
11351 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
11352 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
11354 * tests/autotest.at (Keywords): Test keywords combinations.
11356 2005-08-12 Stepan Kasal <kasal@ucw.cz>
11358 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
11359 add "2>&1"; gzip 1.2.4 prints help on stderr.
11361 2005-07-27 Stepan Kasal <kasal@ucw.cz>
11363 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
11364 was pushdef'ed twice while popped only once. Push it only once.
11365 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
11367 2005-07-26 Stepan Kasal <kasal@ucw.cz>
11369 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
11370 prefixed by mere "===", not "configure: === ".
11372 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
11374 * Makefile.maint: Update from Bison.
11376 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
11377 "<tab>" in comment, so that the point is understandable.
11379 2005-07-25 Stepan Kasal <kasal@ucw.cz>
11381 Rewrite substantial part of lib/autoconf/status.m4.
11382 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
11383 and CONFIG_COMMANDS are not processed in four separate loops.
11384 Instead, there is one main loop. This alows that the common code
11385 is expanded only once, thus config.status (and configure) is smaller.
11387 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
11388 the AC_LIST_FILES and cousins macros are no longer used.
11390 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
11391 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
11392 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
11393 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
11394 contain the initialization, nor the for loop, nor the associated
11395 commands; all these go to ...
11396 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
11397 _AC_OUTPUT_CONFIG_STATUS.
11398 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
11399 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
11400 (_AC_OUTPUT_FILE): The creation of the sed script ...
11401 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
11402 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
11403 _AC_OUTPUT_MAIN_LOOP.
11404 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
11405 _AC_CONFIG_COMMANDS): Use ...
11406 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
11407 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
11408 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
11409 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
11410 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
11411 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
11413 (_AC_CONFIG_UNIQUE): Update.
11414 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
11415 Replaced by this ...
11416 (_AC_LIST_TAGS): ... new common macro.
11417 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
11418 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
11419 (_AC_LIST_TAG_COMMANDS): ... new common macro.
11420 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
11421 this didn't belong to the `config commands' section.
11422 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
11423 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
11424 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
11425 to the `config commands' section either.
11426 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
11427 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
11429 ... and many changes to the comments nearby.
11431 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
11432 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
11433 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
11434 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
11435 (#define header templates): The comment at the top of the generated
11436 header now includes the name(s) of the source file(s).
11438 Several unrelated small changes:
11440 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
11441 parameter to AC_DIAGNOSE.
11442 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
11443 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
11444 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
11445 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
11446 with AU::AC_OUTPUT.
11447 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
11448 in AC_OUTPUT doesn't double-quote it either.
11449 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
11452 2005-07-10 Stepan Kasal <kasal@ucw.cz>
11454 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
11455 versions of Portland Group compiler produce single- and double-quoted
11456 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
11457 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
11459 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
11461 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
11462 This is a corrected version of yesterday's patch.
11464 2005-07-07 Stepan Kasal <kasal@ucw.cz>
11466 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
11467 path, too; insert a "===" to emphasize the line.
11469 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
11470 ac_cv_build_alias to ac_build_alias.
11471 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
11473 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
11474 change eliminates it. Problem reported by Alexandre Duret-Lutz.
11475 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
11476 (AC_ARG_VAR): ... here.
11477 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
11480 Keep a list of all precious variables and process them with one simple
11481 for loop, instead of expanding all commands, or, OTOH, complicated
11482 processing of output of "set".
11483 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
11484 variable names in new macro...
11485 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
11486 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
11487 a loop to assign all ac_env_* and ac_cv_env_* variables.
11488 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
11490 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
11491 its value to shell variable ac_precious_vars and call
11492 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
11493 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
11494 _AC_ARG_VAR_VALIDATE.
11496 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
11497 and the AC_SUBSTs ...
11498 (AC_INIT): ... here.
11500 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
11501 the ac_subst_files section in config.log.

11517 2005-07-05 Stepan Kasal <kasal@ucw.cz>
11519 Fix my changes from 2005-07-01; reported by Noah Misch.
11520 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
11521 description, the macro now accepts only a single tag.
11522 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
11524 Fix cases when the varsions of Autoconf and Autotest don't match.
11525 Reported by Noah Misch.

11527 at_top_builddir, for compatibility with older autotest.
11528 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
11529 is not set, use at_top_builddir, for compatibility with older
11530 versions of autoconf.

11534 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
11535 Problem reported by Patrick Welche.
11537 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
11539 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
11540 sed substitution command, so that we allow | in program prefixes

11544 configure_input, top_builddir, srcdir, etc.
11545 * lib/autotest/general.m4 (AT_INIT): Likewise, for

11548 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
11550 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
11551 for loop over config.site files using `set', to allow
11552 directory names containing IFS characters.
11554 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
11556 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
11557 directories with weird names. Apparently some people like living

11578 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
11579 document to output the default config_* lists to config.status.
11580 Don't recognize option --file, if the functionality is not there.
11581 Likewise for --header; moreover, recognize --he and --h as shortcuts
11582 for --help in that case.
11584 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
11585 matches the order of execution. No code changed.

11604 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
11606 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
11607 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
11608 (AC_SUBST): Call it.
11609 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
11610 the directory specific variables; but don't call it for configure_input.
11612 2005-06-28 Derek Price <derek@ximbiot.com>
11614 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
11617 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
11619 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
11620 directory have inherent problems with special characters like spaces,
11621 due to limitations in Make syntax. Problem reported by Alexandre
11623 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
11624 Also, fix Tru64 porting problem with shell patterns,

11635 Fix some more shell quoting problems. Prompted by a bug report
11636 from Justace Clutter.
11637 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
11638 variable into diagnostic. Make the diagnostic an error, not a warning,
11639 because we really don't support spaces and suchlike in dir names.
11640 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
11641 Don't worry about backslashes in srcdir; it can't happen now.

11652 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
11654 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
11655 that '\|' is not allowed in BREs; recommend using newline separated
11656 list of patterns instead of multiple -e options.
11658 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
11660 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

11666 2005-06-21 Stepan Kasal <kasal@ucw.cz>
11668 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
11669 b, t, r, w commands require single space, while : cannot have any.
11670 (Special Shell Variables): Fix sed code this in the example.
11671 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
11672 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
11674 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
11675 expand to the empty list. Don't use two pairs of m4_changequote,
11676 it's not necessary.
11678 2005-06-20 Derek Price <derek@ximbiot.com>
11680 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
11682 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
11684 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
11685 * doc/autoconf.texi:
11686 Don't mention Solaris versions so much, if a
11687 problem is common to all extant versions of Solaris. Say "SunOS
11688 4" instead of "SunOS" for SunOS 4.
11689 (awk): Mention more of the limitations of traditional Awk.
11690 (cat): Don't talk about cat -v.
11692 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
11694 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.

11697 to be compatible with glibc strverscmp.
11698 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
11700 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

11703 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
11704 Use shell builtins rather than 'expr', to work around expr bug.
11706 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
11708 * doc/autoconf.texi: "filesystem" -> "file system".
11709 "behaviour" -> "behavior".
11710 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
11711 * lib/autoconf/general.m4: Omit blank after ":" sed command,
11713 * lib/m4sugar/m4sh.m4: Likewise.
11714 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
11715 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.

11718 (.x.1): Ignore the time stamp in the .TH line when deciding whether
11719 to update the man page. That way, we don't have to check in new
11720 man pages every month.
11722 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
11723 quotes and backslashes. Patch from Derek Price.

11732 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
11733 -u, since it outputs chatter if the input files are the same.
11734 Problem reported by Ralf Menzel.
11736 2005-06-08 Derek Price <derek@ximbiot.com>
11738 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
11739 renaming them since they are about to be redefined anyhow.
11741 2005-06-08 Derek Price <derek@ximbiot.com>
11743 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
11744 redefined M4 macros to this node. Document m4_include & m4_sinclude.
11745 Move m4_undefine to alphabetical order.
11747 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
11749 * README: Recommend GNU M4 1.4.3 or later.
11750 * doc/autoconf.texi (Introduction): Likewise.
11751 Reword to avoid some formatting glitches.
11752 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
11753 Clarify explanation of HP compiler bug.
11754 Redo example output tp match current CVS snapshot.
11755 Use @example.org in email addresses when the examples
11756 might get inadvertently cut-and-pasted into user code.
11757 Remove example of autom4te usage that doesn't seem to work now.
11758 Use modern AC_INIT (except when the example is meant to be
11759 shown with Autoconf 2.13).
11760 Update ksh info for Solaris 9 and later.
11762 Modernize description of Automake versions a bit.
11763 Don't claim a future version of Autoconf is near.
11764 * doc/install.texi: Reword to avoid some formatting glitches.
11766 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11768 * doc/autoconf.texi: Add [] to examples, so that the manual
11769 follows its own advice about quoting better.
11770 Reword to avoid some formatting glitches.
11771 * doc/installt.exi: Reword to avoid some formatting glitches.
11773 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
11774 Tru64 ksh pattern matching bug. Reported against Libtool by
11775 Albert Chin <libtool@mlists.thewrittenword.com> and
11776 Nicolas Joly <njoly@pasteur.fr>.
11778 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11780 m4_cdr of one-member list was [[]] (one-member list containing an
11781 empty string) instead of [] (an empty list. Callers were skewed to
11782 match this misbehaviour. As a consequence of this:
11783 - m4_foreach([x], [], [foo]) expanded to `foo', while
11784 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
11785 This bug has been fixed:
11787 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
11788 expand to an empty string; print error msg if called without
11790 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
11791 misbehaviour; handle [] and [[]] correctly.
11793 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11795 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
11796 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
11797 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
11799 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
11801 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
11802 swallow records with more than 99 fields.
11803 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
11804 parse the long line.
11806 2005-06-04 Stepan Kasal <kasal@ucw.cz>
11808 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
11809 swallow literals longer than 399. Reported by Ralf Wildenhues.
11810 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
11811 to workaround this limitation.
11813 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
11815 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
11816 to gfortran, and make these the first two compiler names

11821 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
11822 (DISTCLEANFILES): Remove $(check_SCRIPTS).

11827 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
11828 expression of unbounded size when processing the --list
11829 option. This runs afoul of a limit of 399 bytes per regular
11830 expression on AIX. Problem reported by Ralf Wildenhues.
11832 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

11839 Reword description of line replacement.
11841 2005-05-31 Dan Manthey <dan_manthey@partech.com>
11843 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
11844 now contain newlines, and substituted files must be referenced on
11845 a line alone; the sed scripts to substitute them are now very
11847 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
11848 commands can be put in a sed script portably.
11849 * doc/autoconf.texi (Setting Output Variables): Document above
11850 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple

11857 From Ralf Menzel (trivial change).
11859 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
11861 * tests/local.at: Don't attempt to check for negated character
11862 classes in shell scripts. The test was too brittle.
11864 2005-05-25 Stepan Kasal <kasal@ucw.cz>
11866 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

11880 messages when ac_unique_file is not found.
11881 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
11882 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
11883 commands, for consistency with AC_MSG_ERROR and such.
11885 * bin/autoconf.as: Make more use of "shift 2" in option processing.

11899 (ac_top_builddir): ... this ...
11900 (ac_top_build_prefix): ... to this; the old name is also kept, for
11901 backward compatibility.
11902 (ac_top_builddir_sub): New variable, without the trailing slash,

11918 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
11919 argument to m4_foreach. I guess it was necessary in the past,
11920 but I think it's a no-op now.
11922 2005-05-17 Stepan Kasal <kasal@ucw.cz>
11924 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
11925 ``cat <<_ACEOF'' commands to one.
11926 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
11927 * lib/autoconf/status.m4: On various places, use expr instead of

11933 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
11934 the wrong patterns between ``case'' and ``esac.'' The previous
11935 code had false positives.

11999 abbreviations of --version and --debug.
12001 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
12003 * doc/autoconf.texi (Autoconf Language): Be more precise about
12004 quoting rules. Problems noted by Stepan Kasal.
12005 Also, throughout this document, be more careful about white space.
12006 "blank", "white space", and "space" all have different meanings
12007 and we should be careful to say what we mean.
12009 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>

12026 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
12027 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
12028 set by latest automake.
12030 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
12032 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
12033 outputs 0 on GNU/Linux these days.
12035 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
12037 * doc/autoconf.texi (Autoconf Language): Add more description
12038 about quoting heuristics.
12039 (Limitations of Builtins): Describe "set -" problems.
12041 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12043 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
12046 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
12047 by AC_DEFINE; it was a mistake.
12048 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
12050 2005-04-25 Stepan Kasal <kasal@ucw.cz>
12052 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
12054 2005-04-22 Stepan Kasal <kasal@ucw.cz>
12056 * doc/autoconf.texi (External Software): Quadrigraphs are not
12057 processed correctly in AS_HELP_STRING; avoid this in the examples.
12058 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
12059 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
12060 comment and reduce m4_default([foo], []) to [foo].
12061 (m4_strip): Update the explanation.
12063 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
12065 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
12066 Remove core.conftest.* too; it's generated by Tru64 5.1.
12067 Problem reported by Jennis Pruett.
12068 * lib/autoconf/functions.m4
12069 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
12070 Don't bother to remove core files; AC_RUN_IFELSE should do that
12073 2005-04-19 Stepan Kasal <kasal@ucw.cz>
12075 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

12089 * doc/autoconf.texi (External Software, Package Options): Add
12090 examples showing how to implement --with-* and --enable-* options.
12092 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
12094 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
12095 as well as configure.in. Problem reported by Gregorio Guidi.
12097 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
12099 * doc/autoconf.texi (Particular Functions): Use gnulib's current

12113 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
12115 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12117 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
12118 Merge `-z option' as well for the benefit of Solaris link flags. Pass
12119 whole-archive (-zallextract, -zdefaultextract) options in the hope of
12120 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
12121 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
12123 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
12125 * NEWS: The configure command now warns you if you attempt to use
12126 a directory whose name contains a special character like space,
12128 * doc/autoconf.texi (Installation Directory Variables): Allow
12129 "," in file names. Do not use \@; it's not a portable regexp.
12130 * bin/Makefile.am (edit): Likewise.
12131 * lib/Makefile.am (edit): Likewise.
12132 * tests/Makefile.am (edit): Likewise.
12133 * tests/semantics.at: Likewise.

12136 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
12137 * doc/autoconf.texi (File System Conventions): Warn about
12138 unportable file names.
12139 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
12141 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
12142 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
12143 ac_pwd, and quote srcdir.
12144 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
12146 * doc/autoconf.texi: Fix some systematic formatting problems.
12147 ".)" needs a following @: if not at the end of a sentence, and
12148 similarly for "!)". "etc." should be preceded by a comma.
12149 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
12151 2005-03-22 Bruno Haible <bruno@clisp.org>
12153 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
12154 argument is often called 'build-aux'.
12156 2005-03-07 Stepan Kasal <kasal@ucw.cz>
12158 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
12159 macro AC_TRY_LINK is obsolete.
12160 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
12163 2005-02-24 Stepan Kasal <kasal@ucw.cz>
12165 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
12166 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
12167 from a Common Lisp's `cl'.
12168 (AC_PROG_CXX): Behave according to the documentation: don't
12169 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
12170 make the variable CCC precious; use `cl.exe', not `cl'.
12172 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12173 Alexandre Duret-Lutz <adl@gnu.org>
12175 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
12176 /dev/null, as "configure" shouldn't read stdin, and this insulates
12177 us from problems (e.g., when testing for "cl"). Also, do this
12178 redirection before invoking "hostname" or "uname", and keep the
12179 original input stream available via...
12180 (AS_ORIGINAL_STDIN_FD): ... this new macro.
12181 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
12182 bother with "</dev/null" since it's now done at the top of
12184 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
12185 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

12191 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12193 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
12194 newline if neither \c nor -n work, as that would output two
12195 newlines. Prefer -n to \c. Reported by Stepan Kasal.
12197 2005-02-12 Stepan Kasal <kasal@ucw.cz>
12199 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
12200 This causes that any required macros inside will get before the if.
12201 * doc/autoconf.texi (autom4te.cache): A typo.
12203 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
12205 Undo previous change, except keep the change to
12206 lib/autoconf/programs.m4 that replaced grep with shell
12207 pattern-matching. This is because net-snmp configure reads stdin.
12208 Reported by Noah Misch.
12210 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
12212 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
12213 from /dev/null, as "configure" shouldn't read stdin, and this
12214 insulates us from problems (e.g., when testing for "cl").
12215 Suggested by Alexandre Duret-Lutz. Also, do this redirection
12216 before invoking "hostname" or "uname".
12217 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12218 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
12219 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
12220 "</dev/null" since it's now done at the top of 'configure'.
12221 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
12222 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
12223 Also, replace grep with shell pattern-matching, to save a process.
12225 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
12227 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12228 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
12229 avoid thinking that Allegro Common Lisp's "cl" command is a C++
12232 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
12234 * doc/autoconf.texi (Limitations of Usual Tools): Document that
12235 grep -q isn't portable. Improve grep -s explanation.
12236 Problem reported by Dan Manthey.
12238 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
12240 * doc/autoconf.texi (Special Shell Variables): Clarify
12241 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
12243 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
12245 * doc/autoconf.texi: Use @acronym for DJGPP.
12246 Fix some @code's that should have been @env's, and vice versa.
12247 Sort environment variable names.
12248 Mention that shells no longer inherit IFS.
12249 Don't recommend PATH_SEPARATOR=';' so strongly.
12250 Mention that $RANDOM might expand to the empty string.
12251 "symlink" and "soft link" -> "symbolic link".
12252 Improve mktemp description (reported by Bruno Haible).
12254 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
12256 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
12257 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
12259 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
12262 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
12264 * NEWS: Mention AT_COPYRIGHT.
12266 * tests/local.at (AT_CMP): Use diff directly on input files rather
12269 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
12270 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
12272 2005-02-04 Noah Misch <noah@cs.caltech.edu>
12273 and Paul Eggert <eggert@cs.ucla.edu>
12275 * tests/autotest.at (Empty test suite): New test.
12276 * tests/torture.at (Substitute and define special characters)
12277 (Substitute a 2000-byte string, Define to a 2000-byte string)
12278 (Substitute a newline, Define a newline): New tests.
12280 2005-02-04 Noah Misch <noah@cs.caltech.edu>
12282 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
12283 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
12284 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
12285 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.

12287 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
12288 excess test name quoting.
12289 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
12290 CPPFLAGS to `configure' instead of setting it in `configure'.
12292 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
12293 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
12296 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
12297 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
12299 * tests/local.at (AT_CMP): New macro.
12300 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
12301 (AC_SAVE_STATE): Move environment grep...
12302 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
12303 (AT_CONFIG_CMP): New macro.
12304 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
12305 * tests/c.at (Extensions): Do not exit early.

12325 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
12327 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
12328 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
12330 Try not to generated lines of unlimited length, as POSIX places a
12331 2047-byte limit on line length of portable text files.
12332 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
12333 Use newline as a separator, not space.

12340 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
12341 as_func_*. Add test to check whether positional parameters
12342 are restored after function return.
12344 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
12346 * doc/autoconf.texi (Special Shell Variables): Mention _,
12347 BIN_SH, DUALCASE. Say that variables other than "status" are safe
12348 if they contain a lower-case letter. The DUALCASE problem was
12349 reported by Ralf Wildenhues.
12351 * bin/autoconf.as: Don't exit with status 0 after write failure
12352 with --help or --version.
12353 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

12358 * doc/autoconf.texi (Limitations of Usual Tools):
12359 Unicos 9 sed limitations.
12360 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
12361 to get the option-enhanced interface on older Crays. Try ftn for
12362 Fortran 95 (newer Crays).
12364 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
12366 * man/Makefile.am (.x.1): Go back to the simple solution, but take
12367 care to echo the commands, so the user knows what's going on.
12368 Modified from a suggestion by Stepan Kasal.
12370 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
12371 with a cross reference. Derived from a suggestion by Bruce Korb.

12391 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
12392 Update the long comment explaining it.
12394 m4_require no longer writes an ``is required by'' line to the
12395 execution stack. It contains only one bit of non-redundant
12396 information: that the macro was required, not called. And even
12397 this bit is useless in most situations: have you ever met a macro
12398 which both calls and requires the same macro?
12400 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
12401 (_m4_defun_pro_outer): ... only via this macro, for the outermost

12404 (m4_expansion_stack_pop): Remove the misplaced comment.
12405 (m4_require): Don't put the ``is required by'' line to the
12406 execution stack; slightly improve the out-of-a-defun error message.

12408 (_m4_require_call): Use it.
12409 * tests/m4sugar.at (m4_require): Expect output without the
12410 ``is required by'' messages.

12446 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
12448 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
12449 Warn about newline stripping in `` and $(). Update Solaris

12505 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
12506 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
12507 stored in _m4_divert_diversion or _m4_divert_dump.
12508 (m4_divert_pop): When the parameter is given, compare the symbolic
12509 name with the last diversion pushed on the stack. Previously, the
12510 current diversion was compared with the numeric value of the
12511 diversion given as the parameter.
12512 (m4_require): If the macro hasn't been expanded yet, call ...

12797 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
12799 2004-12-07 Stepan Kasal <kasal@ucw.cz>
12801 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

12816 with exactly one parameter.
12818 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
12820 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
12821 "char c = '\200';" rather than "char c = 0x80;" as the
12822 latter doesn't conform to the strict C standard due to

12825 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89

12932 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
12934 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is

12939 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
12940 "/usr/include", clear ac_x_includes instead of leaving it as "no"
12941 (trivial change). Problem and patch reported by Andrew Church in:

12974 Remove ansi2knr.c; nobody uses it.
12975 (ansi2knr.c-url_prefix): Remove.
12976 (cvs-update): Fix test for failure. I don't know why it ever
12979 * doc/autoconf.texi: Update URLs, some of which went stale.
12980 Use @uref rather than @href.
12982 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
12983 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
12985 * config/config.guess, config/config.sub, config/elisp-comp,
12986 config/install-sh, config/mkinstalldirs, config/texinfo.tex,

12996 tests/tools.at, tests/torture.at:
12997 Use "file name" rather than "filename" or "path",
12998 to be consistent with the terminology of the GNU coding standards.
13000 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
13002 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
13003 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
13004 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
13005 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
13007 More fixes to support spaces in the name of the build directory.
13008 This isn't a complete fix but it's an improvement.
13010 * bin/autoconf.as (autom4te_options): New var.
13011 Use it instead of appending to AUTOM4TE, so that we can allow
13012 spaces in the build directory's absolute name.
13013 * bin/autoheader.in ($autoconf): Allow spaces in file names.
13014 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
13015 AT_CHECK_NOESCAPE): Likewise.
13016 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
13017 main program): Likewise.
13019 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
13021 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

13027 * doc/autoconf.texi (Function Portability): Document isinf and
13028 and isnan. From a suggestion by Kevin Ryde.
13030 * lib/Autom4te/General.pm (END): Return correct exit status even
13031 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
13033 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
13035 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
13036 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
13037 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
13039 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
13041 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
13042 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
13043 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
13044 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
13045 * lib/autom4te.in (Automake-preselections): Preselect
13046 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
13048 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
13050 * lib/autom4te.in (Automake-preselections): Preselect
13051 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
13054 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
13056 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
13058 * doc/autoconf.texi (Shellology): Mention BIN_SH.
13059 Document problem with "`""`" in pdksh POSIX mode.
13061 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
13063 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
13064 with pdksh, too. Problem reported by Patrick Welche via
13066 * doc/autoconf.texi (Shellology): Note that set -o posix is
13067 useful for pkdsh, too.
13069 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
13071 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
13072 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
13073 Don't fail if ENV or BASH_ENV is readonly.
13074 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
13075 etc. are read only. Problem reported by Ludovic Courtes.
13077 2004-06-23 Noah Misch <noah@cs.caltech.edu>
13079 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
13080 zsh, disable GLOB_SUBST to avoid backslash handling problems.
13083 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
13085 * doc/autoconf.texi (File System Conventions): Warn about
13086 names like "aux". Problem reported by Eric Blake.
13088 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
13089 by zero instead of array size, so that we can use any arithmetic
13090 constant expression (instead of requiring an integer constant
13091 expression). This allows us to test expressions like DBL_MAX <
13092 LDBL_MAX, which didn't conform to the C standard using the old
13094 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
13095 now that we can do floating-point tests at compile time.
13097 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
13099 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
13100 and LDBL_EPSILON, as the resulting expression isn't an
13101 integer constant expression and violates the C standard.
13102 Problem reported by Nelson H. F. Beebe. Also, check
13103 for "L" suffix, and check that long double doesn't have
13104 worse range or precision than double, that mixed-mode
13105 arithmetic doesn't generate a diagnostic, that double
13106 constants fit in long double.
13108 2004-06-03 Kevin Ryde <user42@zip.com.au>
13110 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
13111 malloc(0) and realloc(NULL,size).
13113 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
13116 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
13118 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
13119 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
13122 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
13124 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
13125 can be rewritten using if-then-else. Suggested by Bruno Haible.
13127 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
13129 * doc/autoconf.texi (testsuite Scripts): Fix typo.
13130 Problem reported by Stepan Kasal.
13132 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
13134 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
13135 change). Patch reported by Ralf Wildenhues in
13136 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
13138 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
13139 function F exists if the compiler and linker let you compile an
13140 expression like (F != 0). Recent versions of GCC optimize away
13141 the reference to F in that case, since every function address must
13142 be nonzero, so the link succeeds even if F does not exist.
13143 Problem reported by Manu in
13144 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
13146 * doc/autoconf.texi (Systemology): Standardize on the spelling of
13147 "Unix". Many uses changed.
13148 (Limitations of Builtins): Explain better why the ! command isn't
13151 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
13153 * lib/autom4te.in (Automake-preselections): Preselect
13154 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
13156 2004-05-19 Kevin Ryde <user42@zip.com.au>
13158 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
13159 referencing AC_FUNC_STRERROR_R.
13161 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
13162 note pessimistic assumption when cross compiling.
13164 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
13166 * doc/autoconf.texi (Limitations of Make): Note that BSD make
13167 (until 2004) invoked subcommands with sh -e, contra POSIX.
13168 Reported by Kevin Ryde.
13170 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
13172 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
13173 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
13174 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
13175 `test -f " /usr/bin/grep"', which _always_ failed.
13176 (AC_PROG_SED): Ditto bogus PATH fix.
13177 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
13178 requires that grep correctly supports _multiple_ `-e' options, rather
13179 than stating only that grep should accept `-e'.
13181 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
13183 Port to C99, which requires that 'exit' be declared.
13185 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
13186 to ensure that stdlib.h is included.
13187 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
13188 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
13189 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
13190 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
13191 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
13192 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
13193 when using 'exit' in a test; C99 requires that 'exit' be declared.
13195 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
13197 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
13198 now prefers 'grep' implementations that accept -e.
13199 (Limitations of Usual Tools): Describe problems of traditional
13200 egrep and fgrep with long input lines, and of traditional grep
13202 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
13203 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
13204 All callers changed. Append /usr/xpg4/bin to the PATH, for
13206 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
13207 the user with complaints about multiple -e options.
13208 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
13209 Define it with AC_PROG_GREP.
13210 * configure.ac (AC_PROG_GREP): Add.
13211 * lib/freeze.mk (GREP): New macro.
13213 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
13215 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
13216 a possible candidate only after all others fail, rather than
13217 consulting it first. This improves backward compatibility by
13218 better reflecting the way shell selection occurred in previous
13219 versions of Autoconf, and should help to avoid triggering latent
13220 problems in other packages, such as the one in Automake where zsh
13221 is not handled robustly:
13222 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
13223 Although it is not Autoconf's responsibility to work around
13224 problems in Automake, it nevertheless makes sense to avoid
13225 introducing unnecessary incompatibilites.
13227 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
13228 Gary V. Vaughan <gary@gnu.org>
13230 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
13231 how deeply nested we are when a suitable tool is found, set the
13232 ac_path_TOOL_found flag.
13233 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
13234 nested we are in this macro. Break out of all 3 nested loops if
13235 ac_path_TOOL_found is set.
13237 2004-04-21 Gary V. Vaughan <gary@gnu.org>
13239 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
13240 of the _AS_PATH_WALK loop too if GNU flavor is found.
13242 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
13244 * doc/autoconf.texi (Limitations of Make): Update documentation
13245 for `$<'. New entry `Long lines', based on a report from Simon
13246 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
13247 paragraph about DJGPP, based on a mail from Richard Dawe.
13249 2004-04-20 Paul Eggert <eggert@twinsun.com>
13251 * tests/c.at (C keywords): Don't assume that GCC supports
13252 "restrict" and "inline", as sufficiently-old GCC versions do not
13253 (also, GCC configured to be in pedantic C89 mode does not).
13254 Problem reported by Sumit Pandya in:
13255 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
13257 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
13258 consider -g to work if it generates warnings when plain compiles
13259 don't. Problem reported by Braden McDaniel in:
13260 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
13262 * doc/autoconf.texi (Slashes): New section, to document a problem
13263 reported by Jim Meyering in:
13264 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
13266 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential

13271 2004-04-20 Gary V. Vaughan <gary@gnu.org>
13273 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
13274 best tool so far counter rely on the tool path variable name to
13275 avoid checks for one tool being affected by the results of running
13276 the length check on a previous tool.
13278 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
13279 match expression argument, as different greps have different
13280 regular expression flavours.

13311 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
13312 now defines HAVE_DECL_TZNAME if it is declared, when
13313 HAVE_STRUCT_TM_TM_ZONE is not defined.
13314 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
13315 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

13362 behavioral changes.
13363 * tests/mktests.sh: Do not generate tests for the
13365 * NEWS: Document these changes.
13367 * doc/autoconf.texi: Avoid macros with unbraced arguments,
13368 they make TeX hang up.

13384 * bin/Makefile.am (edit): Don't use $< in a context where
13385 POSIX doesn't require support for it. Use $@.in instead.
13386 Problem reported by Anthony N. Frasso in
13387 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
13388 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

13393 from the next generation of Libtool.
13394 * lib/autom4te.in (Autoreconf-preselections): Ditto.
13396 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
13398 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
13399 is not always thread-safe. Report from Nathanael Nerode.
13401 2004-02-18 Paul Eggert <eggert@twinsun.com>
13403 Fix a dependencies problem, stemming from a Autoconf 2.59 build
13404 problem on QNX reported by Stephen Rasku in
13405 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
13407 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
13408 $(m4sh_m4f_dependencies); this removes a FIXME.
13409 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
13410 (MAINTAINERCLEANFILES): Split into pieces,
13411 one per related section. Add $(srcdir)/wrapper.in.
13413 2004-02-09 Paul Eggert <eggert@twinsun.com>
13415 * doc/autoconf.texi (Setting Output Variables): Emphasize that
13416 AC_SUBST provides no portable way to escape literal newlines.
13418 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
13419 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
13420 Darwin uses -lcrt2.o and there's little point to cataloging all
13421 the system variants. Partial fix reported by Andreas Waechter in:
13422 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

13438 the behavior of the third argument.
13439 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
13440 correctly the behavior of the third argument. Document
13441 what the three macros that AU_DEFUN defines do. Fix
13442 warning message when the third argument includes $0

13446 Eric Sunshine <sunshine@sunshineco.com>
13447 Paul Eggert <eggert@twinsun.com>
13449 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
13450 (AS_INIT): Output shell initialization there. Removed optional
13451 parameter. Expand _AS_SHELL_FN_SPY.

13460 (_AS_RUN): Move it here, support testing with eval.
13461 (AS_REQUIRE_SHELL_FN): Require shell functions when
13463 (_AS_LINENO_WORKS): Put around braces, we do not
13464 trigger the bash bug anymore.
13465 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
13466 use AS_INIT_WITH_SHELL_FN.
13467 * bin/autoconf.in, tests/wrapper.in: Regenerated.
13469 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

13475 (AU_DEFUN): Honor the third parameter, create autoupdate
13476 macros with AU_DEFINE.
13477 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
13478 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

13497 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
13498 2003 (except 1997) to the list of copyright years. This undoes
13499 the 2003-05-22 change, which removed the older years from the list.
13500 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

13511 egrep and fgrep respectively if $GREP -E/-F don't work.
13512 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
13513 _AC_PROG_GREP, and AC_PROG_SED.
13514 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
13515 longest input length accepted by a command.

13544 2004-01-26 Paul Eggert <eggert@twinsun.com>
13546 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
13547 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
13548 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
13549 not <inttypes.h>. Problem reported by Tim Mooney in
13550 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
13551 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
13554 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
13555 otherwise "make check" fails because it forbids cmp (I guess
13556 because cmp treats files as binary on DOS-like systems).
13558 * tests/mktests.sh: Update copyright date to 2004, since some tests
13559 have changed in 2004.
13561 2004-01-23 Gary V. Vaughan <gary@gnu.org>
13563 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
13564 non-truncating sed or gsed program in PATH.
13565 * tests/acprograms.at: Add it.
13566 * doc/autoconf.texi (Particular Programs): Document it.
13569 2004-01-15 Paul Eggert <eggert@twinsun.com>
13571 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
13572 -std1 disables some useful extensions on Tru64. Problem reported
13573 by N. Lichtmaier in
13574 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
13576 2004-01-14 Paul Eggert <eggert@twinsun.com>
13578 * doc/autoconf.texi (Programming in M4sh): Document that
13579 AS_MKDIR_P succeeds if the destination is a symbolic link
13580 to an existing directory.
13581 (Limitations of Usual Tools): Note that mkdir -p might not
13582 succeed on symlinks to directories.
13584 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
13586 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
13587 * bin/autoheader.in: Grammar fix in message.
13588 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
13589 Test for dir before calling mkdir -p. (trivial changes)
13591 2004-01-13 Eric Blake <ebb9@byu.net>
13593 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
13594 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
13596 2004-01-10 Jim Meyering <jim@meyering.net>
13598 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
13600 2004-01-09 Paul Eggert <eggert@twinsun.com>
13602 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
13603 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
13604 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
13605 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
13606 AC_COMPILE_IFELSE, since we now assume our caller invokes
13607 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
13608 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
13609 of AC_RUN_IFELSE; this avoids the warning mentioned above.
13610 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
13612 2004-01-07 Paul Eggert <eggert@twinsun.com>
13614 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
13615 `"'...'"`, as it's confusing (and I suspect it may not work on
13616 some platforms). The code was incorrect anyway, as it assumed
13617 that \$ evaluated to itself in that context. Reported by
13618 Alexandre Duret-Lutz.
13620 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
13622 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
13623 and _LT_AC_TAGCONFIG.
13625 2004-01-06 Paul Eggert <eggert@twinsun.com>
13627 * doc/autoconf.texi (One Macro Call): Fix an incorrect

13646 by doing lineno substitution only on lines containing "$LINENO".
13648 2004-01-04 Paul Eggert <eggert@twinsun.com>
13650 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
13651 Use "rm -f" to remove conftest.sed, not plain "rm".
13652 Bug reported by David Relson in
13653 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
13655 * Makefile.am (autom4te-update):
13656 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

13672 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
13673 -c -o might not work. From a suggestion by Kevin Ryde.
13674 (C Compiler, Generating Sources, Limitations
13675 of Usual Tools, Limitations of Make, Making testsuite Scripts):
13676 Don't put '-o' after non-options, as POSIX doesn't allow this.
13677 Mention that cc's name might be gcc or c89 or whatever.
13679 2004-01-04 Kevin Ryde <user42@zip.com.au>
13681 * doc/autoconf.texi: Add various further index entries.
13683 2003-12-29 Paul Eggert <eggert@twinsun.com>
13685 * bin/autoreconf.in (autoreconf_current_directory):
13686 Fix typo: mkdir without umask arg.
13688 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
13690 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
13691 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
13692 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
13693 explanation clearer.
13695 2003-12-24 Andreas Schwab <schwab@suse.de>

13795 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
13796 than $target since the latter is not usual, add guidelines on when to

13978 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

14003 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
14004 cache variable instead of $G77 to decide whether to include -O2,

14015 arguments so that it can be used with syntax identical to

14017 remove/deprecate the DIALECT optional argument in the future if it
14018 proves troublesome.
14019 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
14020 non-freeform-supporting compilers. Document freeform flags.
14022 2003-10-03 Akim Demaille <akim@epita.fr>

14091 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
14092 directory for AC_CONFIG_COMMANDS' first argument exists.
14093 This makes valid the invocation of _AC_SRCPATH that follows.
14094 Reported by Eric Sunshine.

14118 The test suite are sometimes assigning timings incorrectly.
14119 Reported by Henk Krus.
14120 Diagnosed by Nicolas Joly.
14122 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
14124 Instead of making AT_help a sequence of assignments to grow
14125 $at_help_all, just make AT_help_all be the growing contents of
14126 $at_help_all, and make a single assignment in...
14128 (at_times_skip): Flip the meaning and rename as...
14129 (at_times_p): this.

14140 (ifnames): chmod -w.
14141 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
14142 executables, not bin/ executables! Otherwise all the magic needed
14143 to find non installed files is turned off. This caused a failure
14144 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
14145 as found in its environment (sent by tests/autoreconf): pointing
14146 to bin/autom4te that could not find its files.
14147 * tests/mktests.sh: Force the replacement of generated files, for
14148 the sake of "mv" program that are interactive when overwriting a

14247 correspond to all the old F77 macros, with output variables FC,

14377 2003-08-21 Akim Demaille <akim@epita.fr>
14379 First stab at preserving warnings between calls to autom4te,
14380 including when the cache is used.
14382 There are still several issues: (i) there are too many runs of m4
14383 (one for include, one for warnings, and some more), (ii) warnings
14384 spreading on several lines are not handled gracefully, (iii) the
14385 code meant to have the call stack display for errors does not work
14386 (its handling should move from m4 to autom4te).
14388 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
14390 (@preselect): Add m4_warn.
14391 ($exit_status): Remove, use $exit_code.
14392 ($help): Use Autom4te::ChannelDefs::usage.
14393 (&handle_m4): No longer define the m4_warnings.
14394 At each run, extract and report the warnings.
14395 Always cache the result, including if the exit status is on
14396 failure, since if nothing changes, we should result in the same
14397 failure, hence we can use the cache.
14398 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
14399 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
14401 (m4_warn): Redefine as a do-nothing: it is its invocation that
14402 matters, as warnings are now reported via traces.
14403 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
14404 the contents of m4_warn: make it _call_ m4_warn, so that tracing
14405 the latter reveals calls to the former.
14409 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
14411 2003-08-21 Akim Demaille <akim@epita.fr>

14431 (&catfile): Remove.
14432 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
14433 * bin/autoscan.in: Adjust.
14435 2003-08-20 Akim Demaille <akim@epita.fr>
14437 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
14438 Reported by Alexandre Duret-Lutz.
14440 2003-08-20 Akim Demaille <akim@epita.fr>
14442 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
14443 * bin/autom4te: Adjust.
14444 In particular, be Autoconf tools are really silent when properly
14445 working, bind the verbosity of the 'note' channel to $verbose.
14446 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
14447 (&xsystem, &contents): Remove, since they are exported by...
14448 * lib/Autom4te/FileUtils.pm: this.

14451 * lib/Autom4te/FileUtils.pm: here.

14570 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
14571 not all of them. This fixes 1. the fact that when testing
14572 Autoconf there are many many config.log, 2. the incorrect use of

14574 Don't mix the detailed output of failed test with the summary of

14681 exit 63, so that we (or Automake's "missing") can tell the
14682 difference with a plain failure.
14683 * doc/autoconf.texi (Notices): Adjust.

14687 * Makefile.am, bin/Makefile.am, config/Makefile.am,
14688 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:

14692 Paul Eggert <eggert@twinsun.com>
14694 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
14695 Remove `#include <stdlib.h>' from the list; we should never
14696 make confdefs.h include <stdlib.h> or <cstdlib>, because the
14697 resulting namespace pollution would cause other tests to fail.
14698 Configure scripts run with some older versions of g++ and HP's
14699 aCC would fail due to such an #include. Problems reported by
14700 Matthew Mueller in <http://bugs.debian.org/120704> and by
14702 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
14703 In the test, use the test declaration before including <stdlib.h>,
14704 as that's closer to how it'll be used.
14706 2003-05-23 Akim Demaille <akim@epita.fr>

14711 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
14713 Overhaul Autotest's logging: generate separate log files
14714 in testsuite.dir/NNN/testsuite.log, and append them to
14715 testsuite.log instead of re-running the test verbosely.
14717 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
14718 file descriptor, write 0 to at_status_file instead of setting
14719 at_status=0, initialize some new variables (at_status_file,
14720 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
14721 to rerun the tests, instead append the at_group_log to the
14722 at_suite_log when a test fails.
14723 (AT_SETUP): pipe the test case's output into at_tee_pipe,
14724 with the AS_MESSAGE_LOG_FD redirected to stdout.
14725 (AT_CLEANUP): save the output status in $at_status_file
14726 and restore it, redirect the AS_MESSAGE_LOG_FD back to
14727 its original place.
14728 (AT_CHECK): since tests are run with a redirected stdout,
14729 and used to be re-run in verbose mode, turn some $at_verbose
14730 into echo, and don't redirect the output of testing stdout
14733 * lib/autotest/autoconf.texi (testsuite Scripts): Update
14734 the name of the debugging directory and information about

14854 2003-05-06 Akim Demaille <akim@epita.fr>
14856 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
14857 longer updates aclocal.m4 if useless, (ii) if a file m4_included
14858 by aclocal.m4 is changed it might require the importing of another
14859 m4 extension file, i.e., aclocal must be run.
14861 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
14862 (&parse_args): Use --force with aclocal if required and supported.

14876 2003-04-29 Derek Price <derek@ximbiot.com>
14878 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
14879 seperator with m4_append_uniq(). It doesn't work.
14880 (AT_CLEANUP): Add `;' to end of at_help_all.
14881 (AT_INIT): Allow --keywords to be specified more than once. When
14882 grepping $at_help_all for keywords, use the field and keyword
14883 seperators to ensure a complete keyword match. Alter at_prev handling
14884 to support the new --keywords behavior.

14888 * doc/autoconf.texi: Make the dir entries in the autoconf manual
14889 align better with others. I also made some of the individual
14890 entries on one line, for brevity and to make it easier for me to
14891 sort my dir-example file in the Texinfo distribution :).

14962 * tests/torture.at (Configuring subdirectories): Require aclocal
14963 1.4, otherwise the test fails, as it does support configure.ac.

15111 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
15112 innocuous variant befor including <limits.h> or <assert.h>. This
15113 works around a bug reported by Albert Chin: HP-UX 11i
15114 (and earlier versions) have a <limits.h> that declares
15115 gettimeofday and many other functions.
15117 2002-12-03 Paul Eggert <eggert@twinsun.com>

15125 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
15126 nontrivially in main's body, so that f's external declaration is
15127 not optimized away in AIX. This should fix the bug reported by
15129 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
15131 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
15132 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
15133 defined, to support freestanding compilers. This should fix the
15134 bug reported by Momchil Velkov in
15135 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
15137 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
15138 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

15145 the location has moved.
15147 2002-12-02 Martin Frydl <martin@systinet.com>
15149 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
15150 \(.*\) match is too long and there is something more to be checked.

15169 Update from masters.
15171 2002-11-14 Akim Demaille <akim@epita.fr>
15173 * Makefile.maint: Sync with Bison, i.e.:
15174 (po-check): Scan .l and .y files instead of the
15175 .c and the .h files that they generate. This fixes the bug
15176 reported by Tim Van Holder in:
15177 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
15178 Look for N_ as well as for _. Try to avoid matching #define for

15199 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
15200 option. Process --recheck after parsing all options. Pass -q
15201 option to configure on --recheck.

15237 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
15239 We _have_ to stop using the old compatibility scheme that tried to
15240 avoid useless backslashes because Libtool 1.4.3 contains a
15241 AC_DEFINE([error_t], [int],
15242 [Define to a type to use for \`error_t' if it is not
15243 otherwise available.])
15244 We _have_ to quote the single quote and backslashes with \. The
15245 old compatibility scheme saw that ` was backslashed, and therefore
15246 did not quote the single quote. Hence before this patch, Autoconf
15247 was not compatible with Libtool.

15292 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
15293 Make variable, not a shell variable.
15294 Suggested by Bruno Haible.

15321 Problem reported by Bruno Haible.

15638 Reported by Alexandre Duret-Lutz.
15640 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

15661 if some file was changed instead of `print'.
15662 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
15663 (&parse_args): Remove the dead options.
15664 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
15665 autoheader's quiet mode.
15666 (AT_CHECK_AUTOUPDATE): Likewise.
15667 * tests/tools.at (autoupdate): Adjust.
15668 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
15670 2002-10-11 Akim Demaille <akim@epita.fr>
15672 No longer use CPP to check for the existing of headers: use CC to
15673 check for compilability.
15675 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
15676 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
15677 (_AC_CHECK_HEADER_NEW): Rename as...
15678 (AC_CHECK_HEADER): this.
15680 * lib/autotest/general.m4 (AT_INIT): Include the failed test
15681 numbers in the Subject suggestion.
15683 2002-10-11 Akim Demaille <akim@epita.fr>
15685 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
15686 Suggest using AC_CHECK_DECLS instead.
15688 2002-10-11 Akim Demaille <akim@epita.fr>
15690 * tests/torture.at (AC_ARG_VAR): Have configure report the value
15693 2002-10-11 Akim Demaille <akim@epita.fr>
15695 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
15696 file name to enable parallel executions.
15697 From Sam Varshavchik.
15699 2002-10-08 Akim Demaille <akim@epita.fr>
15701 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
15702 aclocal invocation, as Gettext macros might not be visible to
15704 Instead of blindly running autopoint, scan configure.ac (not the
15705 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
15706 Reported by Paul D. Smith.
15708 2002-10-08 Paul Eggert <eggert@twinsun.com>
15710 Work around problems found when POSIXLY_CORRECT=1 is set.
15711 None of this seems to have anything to do with POSIX, really,
15712 but it's how Perl getopt works.
15713 * bin/autom4te.in (parse_args): Configure GetOpt with
15715 * doc/autoconf.texi (Invoking autom4te):
15716 --warning -> --warnings.
15717 * lib/autom4te.in: --warning -> --warnings.
15719 2002-09-28 Akim Demaille <akim@epita.fr>
15721 * doc/autoconf.texi (autom4te.cache): New section.
15723 2002-09-28 Akim Demaille <akim@epita.fr>
15725 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
15726 (Automake-preselections): Update.
15727 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
15729 2002-09-28 Akim Demaille <akim@epita.fr>
15731 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
15732 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
15733 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
15734 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
15736 2002-09-28 Akim Demaille <akim@epita.fr>
15738 * tests/torture.at (Configuring subdirectories): Be robust to
15739 users who use config.site to require for a cache: in this case,
15740 the two last configure runs, using two different sets of
15741 arguments, trigger a legitimate error.
15743 2002-09-28 Akim Demaille <akim@epita.fr>
15745 * tests/m4sh.at (Functions Support, Functions and return Support):
15748 2002-09-28 Akim Demaille <akim@epita.fr>
15750 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
15751 autoheader are Perl programs.
15752 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
15753 (autom4te): Specify that the sources are in the $srcdir.

15761 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
15762 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
15763 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
15764 * lib/autoconf/programs.m4: here.

15776 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
15777 (.m4.m4f): Don't pass --prepend-include, since that's done by
15778 tests/autom4te itself.
15779 * lib/autoscan/Makefile.am: Include freeze.mk.
15780 (autoscan.list): New target --this file is no longer a source.
15781 (autoscan.pre): New file.
15783 2002-09-28 Akim Demaille <akim@epita.fr>
15785 * bin/autoscan.in (@kinds): Make them singular.
15787 (&init_tables): When --debug, report the list of rules to ease
15788 tracking changes in autoscan.list.
15789 * lib/autoscan/autoscan.list (function): Strip comments, sort.
15791 2002-09-28 Akim Demaille <akim@epita.fr>
15793 * lib/autoscan/functions, lib/autoscan/headers,
15794 * lib/autoscan/identifiers, lib/autoscan/makevars,
15795 * lib/autoscan/programs: Merge into...
15796 * lib/autoscan/autoscan.list: this.
15797 * bin/autoscan.in (&init_tables): Adjust.
15799 2002-09-28 Akim Demaille <akim@epita.fr>
15801 * lib/autoscan/functions, lib/autoscan/headers,
15802 * lib/autoscan/identifiers, lib/autoscan/makevars,
15803 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
15804 `functions' line is now prefixed with `function:'.
15805 * bin/autoscan.in (&init_tables): Adjust.
15807 2002-09-28 Akim Demaille <akim@epita.fr>
15809 From now on, autoscan files must always map a macro name to a
15810 word: there is no `default' macro for autoscan.
15812 * bin/autoscan.in (&init_tables): Reject entries with no macro at
15814 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
15817 2002-09-28 Akim Demaille <akim@epita.fr>
15819 * bin/autoscan.in (%c_keywords): Remove.
15820 (&used): Keep only track of the words we might be interested in.
15821 (&output_kind): It is no longer needed to look for non active
15824 2002-09-27 Akim Demaille <akim@epita.fr>
15826 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
15827 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
15828 * lib/autoscan/functions: Adjust.
15829 * doc/autoconf.texi (Particular Functions): Adjust.
15831 2002-09-27 Akim Demaille <akim@epita.fr>

15835 Thanks to Bill Moseley and Paul Eggert.
15836 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
15837 the tmpdir must be created.
15838 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
15839 dir be in the build tree, instead of $TMPDIR.
15841 2002-09-27 Akim Demaille <akim@epita.fr>
15843 * bin/autoscan.in: Improve the comments.
15844 (&parse_args): Drop obsolete undocumented options.
15845 (&output_kind): Output warnings.
15846 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
15847 (getwd): Trigger a warning.
15849 2002-09-26 Akim Demaille <akim@epita.fr>
15851 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
15852 Reported by Ralf Corsepius.
15853 * doc/autoconf.texi (autoreconf Invocation): Likewise.
15855 2002-09-26 Akim Demaille <akim@epita.fr>
15857 Single suffix rules and seperated dependencies are not portable.
15859 * doc/autoconf.texi (Installation Directory Variables): Update.
15860 (Limitations of Make): Some about `Single Suffix Rules and
15861 Separated Dependencies'.
15862 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
15863 (ifnames, autoscan, autom4te): Un-factor into several rules.
15865 2002-09-25 Paul Eggert <eggert@twinsun.com>
15867 * BUGS (Interoperability bugs): New section. Mention libtool
15868 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
15870 2002-09-24 Paul Eggert <eggert@twinsun.com>
15872 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
15873 make handles suffix-rules differently from GNU make.
15875 * bin/Makefile.am (SUFFIXES, .in): Remove.
15876 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
15877 Move the body of the old .in rule here.
15879 2002-09-16 Akim Demaille <akim@epita.fr>
15881 i960 compilers create `b.out' files by default.
15882 Reported by Ralf Corsepius.
15884 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
15885 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
15887 2002-09-13 Paul Eggert <eggert@twinsun.com>
15889 * doc/autoconf.texi (Particular Headers): Remove obsolete
15890 reference to `struct timezone' in the description of
15893 2002-09-13 Akim Demaille <akim@epita.fr>
15897 * config/config.sub, config/config.guess: Update.
15898 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
15899 * Makefile.am: Adjust.
15901 2002-09-13 Akim Demaille <akim@epita.fr>
15903 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
15904 reading config.log when the compiler is rejected.
15905 Suggested by Guido Draheim.
15907 2002-09-13 Akim Demaille <akim@epita.fr>
15909 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
15910 (chdir_init) might hang when stat'ing mounted directories.
15911 Reported by Vance Shipley.
15913 2002-09-12 Akim Demaille <akim@epita.fr>
15915 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
15918 2002-09-12 Akim Demaille <akim@epita.fr>
15920 * doc/autoconf.texi (Defining Symbols): Present two different
15921 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
15922 difference between 1 argument calls, and 2-3 argument calls.
15924 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
15926 * doc/autoconf.texi: Review grammar and punctuation.
15928 2002-09-11 Paul Eggert <eggert@twinsun.com>
15930 * doc/autoconf.texi: Fix minor formatting, spelling, and
15932 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
15933 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
15936 2002-09-11 Akim Demaille <akim@epita.fr>
15938 * doc/autoconf.texi (Questions): Rename as...
15940 (Defining Directories): New.
15942 2002-09-09 Akim Demaille <akim@epita.fr>
15944 * doc/autoconf.texi (Making testsuite Scripts): Update.
15945 Suggested by Nishio Futoshi.
15947 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
15949 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
15950 plain `@' is wanted.
15952 2002-09-09 Akim Demaille <akim@epita.fr>
15954 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
15955 `duplicates', since the algorithm was too naive and could keep
15956 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
15957 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
15958 Reported by Ralf Corsepius.
15959 * tests/torture.at (Configuring subdirectories): Exercise these
15962 2002-09-09 Akim Demaille <akim@epita.fr>
15964 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
15965 looking for a replacement file.
15966 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
15967 directory is relative.
15968 * doc/autoconf.texi (Generic Functions): Clarify the replacement
15969 directory definition.
15970 Reported by Andreas Schwab and Jim Meyering.
15972 2002-09-06 Akim Demaille <akim@epita.fr>
15974 * doc/autoconf.texi (Setting Output Variables): Clarify what
15975 precious variables are.
15976 Suggested by Pontus Skoeld.
15978 2002-09-05 Akim Demaille <akim@epita.fr>
15980 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
15981 (ifnames, autoscan, autom4te): Since we don't only depend on
15982 configure.ac variables (such as VERSION etc.), but also on prefix
15983 and so forth, depend on Makefile, not configure.ac.
15984 Reported by Alexandre Duret-Lutz.
15985 * doc/autoconf.texi (Installation Directory Variables): Adjust.
15987 2002-09-05 Kevin Ryde <user42@zip.com.au>
15989 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
15990 doesn't seem to be confined to ia64, just say "some versions".
15992 2002-09-04 Akim Demaille <akim@epita.fr>
15994 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
15996 * Makefile.am (maintainer-clean-local): Remove.
15997 (MAINTAINERCLEANFILES): Remove COPYING.
15999 2002-09-03 Paul Eggert <eggert@twinsun.com>
16001 * doc/autoconf.texi (Configuration Commands): Remove obsolete
16002 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
16005 2002-09-03 Akim Demaille <akim@epita.fr>
16007 * configure.ac: Bump to 2.53d.
16008 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
16009 as of today, on Automake's team suggestion.
16011 2002-09-03 Akim Demaille <akim@epita.fr>
16015 2002-09-02 Akim Demaille <akim@epita.fr>
16017 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
16019 * configure.ac: Disable SITE_MACRO_DIR.
16021 2002-09-02 Jim Meyering <meyering@lucent.com>
16023 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
16024 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
16025 Also, tweak grammar: s/make sure to/be sure to/.
16027 2002-09-02 Paul Eggert <eggert@twinsun.com>
16029 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
16030 directory names are generally preferable to physical names.
16032 2002-09-02 Akim Demaille <akim@epita.fr>
16034 * lib/Autom4te/General.pm (&update_file): s/die/error/.
16035 Reported by Raja R. Harinath.
16036 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
16037 * bin/autoupdate.in: Use error instead of die.
16039 2002-09-01 Paul Eggert <eggert@twinsun.com>
16041 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
16042 ordinary shell concatenation rather than echo+tr+sed command that
16043 runs afoul of a long-line-related sed bug in Solaris 8.
16045 * bin/autoheader.in (parse_args): --warning -> --warnings.
16047 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
16048 stdout, as traditional "ls" does.
16049 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
16050 _AC_COMPILER_EXEEXT_O): Likewise.
16051 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
16053 * bin/autoconf.as: Add --prepend-include option. This patch was
16054 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
16055 but bin/autoconf.in is generated automatically from bin/autoconf.as.
16057 * bin/autoconf.in, configure: Regenerate.
16059 * doc/autoconf.texi (Special Shell Variables): Mention
16060 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
16062 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
16063 MAILPATH and set PS1, PS2, PS4 to default values, to work
16064 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
16065 For LC_ALL etc, first try to set to "C" as POSIX requires and as
16066 the Autoconf documentation specifies; fall back to "unset" only if
16067 this fails. Use a shell for-loop for this rather than an m4 loop,
16068 to shorten the output script.
16070 2002-08-30 Paul Eggert <eggert@twinsun.com>
16072 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
16073 1003.1-2001's requirements for CDPATH. Give a simpler workaround
16074 for the CDPATH problem. Document PWD.
16075 (Limitations of Builtins): Document the problem that "cd $foo" and
16076 "ls $foo" may refer to different directories in shells conforming
16077 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
16078 example, since the old example is now out of date.
16080 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
16081 FOO" and "ls FOO" talk about different directories; this catches
16082 problems when POSIX 1003.1-2001 "cd" fails due to symlink
16085 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
16086 of rolling our own unset.
16087 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
16088 in practice we needn't worry about CDPATH if unset doesn't work.
16090 * Makefile.in, aclocal.m4, bin/Makefile.in,
16091 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
16092 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
16093 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
16094 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
16095 tests/Makefile.in: Regenerate with Automake 1.6.3.
16097 * config/config.guess, config/config.sub, config/mkinstalldirs:
16100 * configure: Regenerate with self.
16102 2002-08-30 Kevin Ryde <user42@zip.com.au>
16104 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
16107 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
16109 * bin/autom4te.in (Request::load): Correctly test for "do" read
16112 2002-08-29 Akim Demaille <akim@epita.fr>
16114 * lib/Autom4te/General.pm (&xqx): New.
16115 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
16116 hand, which is not portable.
16118 * bin/autom4te.in: Use them.
16119 Use &error instead of die.
16120 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
16123 2002-08-17 Paul Eggert <eggert@twinsun.com>
16125 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
16126 default list of compilers to try, since it was long ago superseded
16127 by the ksh fc builtin. Suggested by Steven G. Johnson.
16129 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
16131 * doc/autoconf.texi (Invoking autom4te): End the option table,
16132 fixing a bug introduced by the previous patch.
16133 (Limitations of Make): Add a 'target lookup' subentry in the
16134 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
16136 2002-07-29 Mark D. Roth <roth@feep.net>
16138 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
16139 options and use $AUTOM4TE_PATH.
16140 * doc/autoconf.texi: Remove documentation of autom4te
16141 --include-envvar and --site-macro-subdir options and document
16142 use of $AUTOM4TE_PATH.
16143 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
16144 arguments from each language section.
16146 2002-07-29 Paul Eggert <eggert@twinsun.com>
16148 * doc/install.texi: Include copyright symbol in copyright notice.
16150 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
16152 (AM_MAKEINFOFLAGS): New macro.
16153 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.

16443 This improves on an earlier suggestion by H. Peter Anvin.
16445 2002-05-16 Paul Eggert <eggert@twinsun.com>
16447 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
16448 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
16449 Both macros now accept an optional source-dir arg.
16450 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
16452 * NEWS: Document this.
16453 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
16455 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
16456 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
16457 not for GNU extensions; this undoes part of the 2000-11-03 change,
16458 reverting to 2.13-compatible behavior.
16459 Add new optional argument DIR.
16460 (AC_FUNC_FNMATCH_GNU): New macro.
16462 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.

16466 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
16467 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
16468 and it causes a 'test' syntax error if it fails.
16469 Bug reported by Stephen Gildea.
16471 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
16472 If prototypes are supported, use them to check this at compile-time,
16473 instead of trying to check it at run-time. If we must do a run-time
16474 check, assume that setvbuf is standard when cross-compiling, as
16475 nonstandard setvbuf occurs only on ancient and unlikely hosts.
16476 Bug reported by Paul D. Smith.
16478 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
16479 argument specifying location of getloadavg.c. This removes a
16480 FIXME. This idea was taken from Jim Meyering's implementation in
16482 * doc/autoconf.texi (Particular Functions): Document this.
16483 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
16484 that's what the code does; this fixes a bug reported by

16489 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
16490 autopoint instead of gettextize.
16491 ($uses_alocal): Rename as...
16492 ($uses_aclocal): this.
16493 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16494 Suggested by Bruno Haible.
16496 2002-05-03 Akim Demaille <akim@epita.fr>
16498 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
16500 2002-04-29 Paul Eggert <eggert@twinsun.com>
16502 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
16503 files to be 1 second older; just set them to be the same time.
16504 Also, sleep 1 second after the first aclocal, to work around
16505 problems with sub-second time stamps on the input files.
16507 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
16509 * doc/autoconf.texi: Mention "set -e -x" lossage
16510 under node "Limitations of Builtins".

16516 From Christian Cornelssen.
16518 2002-04-29 Akim Demaille <akim@epita.fr>
16520 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
16521 of lack of $LINENO support, then the test will compare the $LINENO
16522 in testsuite vs. the lineno in the test file. This is wrong, of
16524 Be sure to protect it.
16525 Reported by Patrick Welche.
16527 2002-04-25 Akim Demaille <akim@epita.fr>
16529 * doc/autoconf.texi (Obsolete Macros): Typo.
16530 Reported by Vladimir Volovich.
16532 2002-04-25 Akim Demaille <akim@epita.fr>
16534 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
16535 than some of the input files, hence, on the second run of aclocal,
16536 if some of its input are younger, make them older.
16537 Suggested by Paul Eggert.
16539 2002-04-25 Akim Demaille <akim@epita.fr>
16541 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

16547 and ac_subst_vars be sh variables containing the list of
16548 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
16550 (_AC_INIT_PREPARE): Use them to log them.
16551 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
16552 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
16553 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
16554 _AC_SUBST_FILES and _AC_SUBST_VARS.
16555 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
16557 2002-04-24 Akim Demaille <akim@epita.fr>
16559 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
16560 autoheader, so that automake does not complain about a missing
16561 config.h.in that was to be created.
16563 2002-04-23 Akim Demaille <akim@epita.fr>

16647 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
16649 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
16650 from aclocal.m4 too.
16652 2002-04-12 Akim Demaille <akim@epita.fr>
16654 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
16656 2002-04-10 Akim Demaille <akim@epita.fr>
16658 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
16659 workaround for ${1+"$@"}.
16660 * doc/autoconf.texi (Shell Substitutions): Explain it.
16661 From Oliver Kiddle and Peter Stephenson.
16663 Have M4sh perform minimal shell sanitizing.
16665 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
16667 (_AS_PREPARE): this new macro.
16669 (AS_INIT): Invoke AS_SHELL_SANITIZE.
16670 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
16672 Adjust Autoconf and Autotest.
16674 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
16675 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
16676 * lib/autotest/general.m4 (AT_INIT): Likewise.
16677 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
16678 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
16681 Use this M4sh to generate Autoconf's shell scripts.
16683 * tests/wrapsh.as: New, precursor of wrapsh.in.
16684 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
16685 on Autotest and M4sh.
16686 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
16687 (wrapsh.in): New target.
16688 * bin/autoconf.as: New, precursor of autoconf.in.
16689 (autoconf.in): New target.
16691 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

16694 with indented comments in rules.

16709 directories when descending in a SUBDIRS.
16710 Reported by Ezra Peisach.
16712 2002-04-04 Andreas Schwab <schwab@suse.de>
16714 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
16715 contains no literal separators.
16717 2002-04-03 Akim Demaille <akim@epita.fr>
16719 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
16720 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
16721 Use dnl, not the KILL diversion.
16723 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
16724 (AC_CONFIG_LINKS): here.
16726 Don't use the KILL diversion, as it kills spurious output, which
16727 results in failures being hidden.
16728 Use m4_defn where appropriate.
16729 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
16730 after the second argument.
16732 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
16733 syntax, as it is provided by M4sugar.
16734 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
16736 2002-04-03 Andreas Schwab <schwab@suse.de>

16755 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
16757 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.

16761 (AC_C_CONST): Same.

16771 _AS_MKDIR_P_PREPARE.
16773 2002-03-28 Kevin Ryde <user42@zip.com.au>
16775 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
16776 to avoid versions of HP C which don't allow that.
16778 2002-03-27 Paul Eggert <eggert@twinsun.com>
16780 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
16781 (AS_SHELL_SANITIZE): Invoke it.
16782 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

16786 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
16788 2002-03-26 Akim Demaille <akim@epita.fr>
16790 * doc/autoconf.texi (Introduction): The GNATS base moved.
16792 2002-03-25 Paul Eggert <eggert@twinsun.com>
16794 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
16795 as POSIX requires, as it doesn't work with Zsh.
16796 * doc/autoconf.texi (Assignments): Document the problem.
16798 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
16800 * doc/autoconf.texi (Limitations of Make): Mention more issue
16801 about VPATH, overriding of macros in sub-makes, and handling of
16804 2002-03-21 Paul Eggert <eggert@twinsun.com>
16806 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
16807 problem with here-document buffer boundaries.
16809 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
16810 when reinvoking the shell, to work around problems with installers
16811 who put strange things like "cd" commands in their environments.
16813 2002-03-19 Akim Demaille <akim@epita.fr>
16815 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

16827 From Nishio Futoshi.
16829 2002-03-19 Akim Demaille <akim@epita.fr>
16831 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

16835 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
16836 (Limitations of Usual Tools): Add mkdir section.
16838 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
16839 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
16840 back on AS_DIRNAME to compute prefixes otherwise; this is
16841 roughly what mkinstalldirs does. That way, we need not have
16842 our own filename disassembler. The old disassembler did not
16843 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
16845 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
16846 Create at_test_all by a series of assignments,
16847 not by a single assignment of a long string. The latter causes ksh
16848 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
16849 presumably because of a buffer overrun.
16851 2002-03-14 Paul Eggert <eggert@twinsun.com>
16853 * lib/autotest/general.m4 (at_times_skip):
16854 Renamed from at_times. Now a boolean.
16855 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
16856 says 'times: not found'.
16858 2002-03-14 Akim Demaille <akim@epita.fr>
16860 * bin/autoreconf.in (&study_gettextize): New.
16861 (&autoreconf): Handle newest gettextize.

16885 2002-03-11 Andreas Schwab <schwab@suse.de>

16888 does not do it if --with-lispdir is given.

16897 subdirectory should exist.
16899 2002-03-08 Akim Demaille <akim@epita.fr>
16901 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
16903 2002-03-08 Akim Demaille <akim@epita.fr>
16905 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
16906 aliases the actual variables, and modifications of the former
16909 2002-03-08 Akim Demaille <akim@epita.fr>
16911 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
16912 because of C-c: have m4 output in tmp files, then mv them.
16914 2002-03-08 Akim Demaille <akim@epita.fr>

16935 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
16936 * lib/autoconf/general.m4 (AC_INIT): More informative error
16937 message for LIBOBJ.
16939 2002-03-04 Akim Demaille <akim@epita.fr>

16944 2002-03-04 Akim Demaille <akim@epita.fr>
16946 * doc/autoconf.texi (Transforming Names): Equality between target
16947 and host is irrelevant.
16948 (Specifying Names, Canonicalizing): Remove all references to the
16949 backward compatibility hooks. Rather, collect them all into...
16950 (Hosts and Cross-Compilation): this new section.
16951 * doc/install.texi (System Type): Ditto.
16952 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
16953 that `--host' implies cross-compilation.
16955 2002-03-04 Akim Demaille <akim@epita.fr>
16957 * doc/autoconf.texi (Evaluation Macros): New.
16958 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
16960 (_m4_foreach): Define the variant with immediate evaluation so
16961 that it contains exactly the items, not an expression which
16962 evaluation is the current item.
16963 (m4_re_string, m4_re_word): Don't over quote them.
16965 2002-03-04 Akim Demaille <akim@epita.fr>
16967 Instead of having stacking `shift's evaluated at the end, let
16968 `foreach' loops immediately evaluate them.
16970 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
16971 $*. This is the n-th time I change my mind, but hopefully this is
16974 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
16976 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
16977 it was only a hack for m4_text_wrap.
16978 (m4_car2): Remove, replaced by...
16980 (_m4_foreach): Adjust.
16981 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
16982 m4_bpatsubst for clarification.

17033 Fix Autoconf PR/207:
17034 AC_PREFIX_PROGRAM fails with dashed program names
17036 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
17037 variable when looking for the prefix program.
17038 Now it also works for shell variables.

17073 2002-02-05 Akim Demaille <akim@epita.fr>
17075 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

17095 2002-02-05 Akim Demaille <akim@epita.fr>
17097 * bin/autom4te.in (&parse_args): Implement `frozen files are
17098 optional are the sum of the previous files on the command line'.
17099 Also, pass `--reload-state=' on them, so...
17100 (handle_m4): don't.
17101 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
17102 (M4sh): Rely on M4sugar.
17103 (Autotest, M4sh, M4sugar): Use frozen files.

17117 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one

17119 is now run with GCC only.

17127 change AC_INIT default values.
17129 2002-01-29 Akim Demaille <akim@epita.fr>
17131 * tests/torture.at (Configuring subdirectories): Use configure.in,
17132 so that aclocal 1.4 works.
17133 Reported by Alexandre Duret-Lutz and Larry Schmitt.
17135 2002-01-28 Akim Demaille <akim@epita.fr>
17137 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
17140 2002-01-28 Akim Demaille <akim@epita.fr>
17142 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
17143 AUTOTEST_PATH *after* it was set.
17144 Don't put `.' in the PATH: the user should be precise and `./' if
17145 needed. In addition, given that the test suite does some `cd', if
17146 `.' is in the path, the `tested programs' sections will report
17147 programs found in the test suite's directory, while during the
17148 tests (performed in their own directory), these programs are no
17149 longer visible. In other words, the results is confusing and
17151 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

17217 package.m4, since is really depends upon configure.ac, not
17219 * doc/autoconf.texi (testsuite Scripts): Adjust.
17220 * tests/Makefile.am (package.m4): New.
17221 EXTRA_DIST it since its a source.
17223 2002-01-06 Akim Demaille <akim@epita.fr>
17225 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
17226 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
17227 and PACKAGE_BUGREPORT from here...
17228 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
17230 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
17231 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
17232 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.

17255 2001-12-14 Akim Demaille <akim@epita.fr>
17257 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
17258 trailing files, don't apply `-rf' to files which might not be
17259 created by configure (core, core.*, and *.core), but just `rm -f'.
17260 Suggested by Jonathan Kamens.
17262 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
17264 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

17268 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
17270 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

17273 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
17274 abs_srcdir, top_srcpath to abs_top_srcdir.
17275 (_AC_OUTPUT_FILES): Adjust.
17276 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
17277 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
17278 * tests/wrappl.in, tests/wrapsh.in: Adjust.
17280 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>

17286 2001-12-12 Kevin Ryde <user42@zip.com.au>
17288 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
17289 forbidden file descriptors table.
17291 2001-11-26 Akim Demaille <akim@epita.fr>
17293 * bin/autoscan.in (%c_keywords): Build it at top level.
17294 Map to 1 in order to simplify its uses.
17296 2001-11-26 Akim Demaille <akim@epita.fr>
17298 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
17299 Remove $filepath, useless.
17300 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
17301 variables, they are really part of the tokens.
17302 Split the input line on spaces and then look for tokens.
17303 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
17304 because of `lex$U.$(OBJEXT)'.
17305 (&scan_files): Use "@list" instead of join.
17306 * doc/Makefile.am (CLEANFILES): Add *.fns.
17308 2001-11-26 Akim Demaille <akim@epita.fr>

17311 Remove, replaced by...
17312 * tests/wrappl.in: Be common for all the Perl executables.
17313 In particular autoscan and autoheader want -I.
17314 * configure.ac: Adjust.
17315 * lib/autoscan/headers: errno.h is portable.
17317 2001-11-26 Akim Demaille <akim@epita.fr>
17319 * bin/autoscan.in (used): New.
17322 2001-11-26 Akim Demaille <akim@epita.fr>
17324 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
17326 (&scan_sh_file): Remove a duplicate pattern.
17327 (&check_configure_ac): Use long options.

17332 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
17333 Before, having a line containing the opening of a multi line
17334 comment made the whole line be ignored.
17336 2001-11-26 Akim Demaille <akim@epita.fr>
17338 * doc/autoconf.texi (Using an Autotest Test Suite): New.

17344 Test groups are now run two directories deeper.
17346 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
17347 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
17349 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
17350 top_srcdir, builddir and top_builddir.
17351 Use `at_*dir' relatively to the directory containing the
17352 suite, use `*dir' when relatively to the current group dir.
17354 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
17356 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
17357 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
17358 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
17361 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17363 * doc/autoconf.texi (Using System Type): Add an example of `case
17364 $host' usage so people quit using `case $target' everywhere.
17366 2001-11-22 Akim Demaille <akim@epita.fr>
17368 * doc/autoconf.texi (Installation Directory Variables): Englishoes
17369 spotted by Jim Meyering.
17371 2001-11-16 Paul Eggert <eggert@twinsun.com>
17373 This patch implements a `long double' suggestion by Oliver Kiddle.
17375 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
17376 static, to catch errors if the value isn't known at compile-time
17377 and the compiler supports dynamic arrays. Change its name from
17378 `_array_' to `test_array' to avoid potential name clashes.
17379 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
17380 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
17381 better than double. Catch a bug in GCC 2.95.2 x86.
17382 * doc/autoconf.texi (C Compiler): Document the above.
17385 2001-11-13 Akim Demaille <akim@epita.fr>
17387 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
17389 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
17391 2001-11-13 Akim Demaille <akim@epita.fr>
17393 * lib/autotest/general.m4 (AT_INIT): After having run the test
17394 group, go back to the initial directory, not to at_suite_dir.
17396 2001-11-13 Akim Demaille <akim@epita.fr>
17398 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
17399 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
17400 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
17402 (AT_CHECK_CONFIGURE): Use absolute paths.
17403 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
17404 The problem is still the old one: there is no means in M4 (that I
17405 know about) to create a defining macro, because there is no means
17406 to create `$1' etc., therefore, the defining macro ``swallows''
17407 all the arguments meant to the defined macro.
17409 2001-11-13 Akim Demaille <akim@epita.fr>
17411 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
17412 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
17414 * tests/aclocal.m4: Remove, as it is no longer used.
17416 2001-11-13 Akim Demaille <akim@epita.fr>
17418 * lib/autotest/general.m4: Change `tests?' into `groups?' in
17419 variable names when referring to a single test group, or to
17420 `suite' when referring to the whole test suite.
17421 `at_last_test' is removed: m4 compute at_format itself.
17422 (at_stdout, at_stder1, at_stderr): New variables.
17423 (AT_CHECK): Use them.
17425 2001-11-13 Akim Demaille <akim@epita.fr>
17427 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
17429 Create `testsuite.dir/003/run' instead of `testsuite.003'.
17430 Do it as soon as a test fails, don't wait till the end of the test
17432 Don't remove $as_me.[0-9]*, since these files no longer exist.
17434 2001-11-13 Akim Demaille <akim@epita.fr>
17436 * tests/tools.at: Use absolute paths, since we are no longer run
17439 2001-11-13 Akim Demaille <akim@epita.fr>
17441 Now that tests are running in their own private dir, there is no
17442 need to list the files to remove at the end of tests groups.
17444 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
17445 (AT_data_files, at_data_files): Remove.
17446 (AT_CLEANUP, AT_DATA): Simplify.
17448 Remove the group dir if !debug && !failed.
17449 * tests/atspecific.m4: Adjust.
17451 2001-11-13 Akim Demaille <akim@epita.fr>
17453 Start a new layout for Autotest: `testsuite' creates
17454 `testsuite.dir' in which the at-check-line etc. files are to be
17455 found, and `testsuite.dir/003' where the test group 3 is run.
17457 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
17458 at_check_line_file, at_format, at_test_normalized, at_group_dir
17460 Create the directories.
17461 Use absolute paths for at- files.
17462 (AT_CHECK): Adjust.
17464 2001-11-11 Michael Matz <matz@kde.org>
17466 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
17468 (m4_car): Properly quote arguments.
17470 2001-11-13 Akim Demaille <akim@epita.fr>
17472 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
17473 with stricter rules on LIBOBJS.
17475 2001-11-12 Paul Eggert <eggert@twinsun.com>
17477 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
17478 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
17481 2001-11-12 Akim Demaille <akim@epita.fr>
17483 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
17485 2001-11-12 Akim Demaille <akim@epita.fr>
17487 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
17488 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
17489 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
17490 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
17491 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
17492 specify to what the macro should be defined (typically to 1).
17494 2001-11-12 Akim Demaille <akim@epita.fr>
17496 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
17499 2001-11-12 Akim Demaille <akim@epita.fr>
17501 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
17502 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
17503 definition used by Automake where LEX is +/- "${missing} lex" and
17504 `missing' itself contains variables.
17506 2001-11-12 Akim Demaille <akim@epita.fr>
17508 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
17509 Now that M4sh pushes BODY, the comments were output at the end of
17512 2001-11-08 Akim Demaille <akim@epita.fr>
17514 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
17515 that we can trace macros from aclocal.m4.
17516 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
17517 obsoleted, and redirect to the former anyway.
17518 Reported by Ralf Corsepius.
17520 2001-11-08 Akim Demaille <akim@epita.fr>
17522 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
17523 processed only if present.
17524 * tests/torture.at (Configuring subdirectories): Use autoreconf
17525 instead of successive calls to autoconf.
17526 Add a nonexistent subdirectory to exercise the patch above.
17527 Reported by Ralf Corsepius.
17529 2001-11-08 Kevin Ryde <user42@zip.com.au>
17531 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc

17539 * bin/autom4te.in (warn_forbidden): New.
17540 (handle_output): Use it.
17541 Read m4_pattern_forbid with messages.
17543 2001-11-05 Akim Demaille <akim@epita.fr>
17545 * bin/autom4te.in (--normalize): Remove.
17546 * lib/autom4te.in: Adjust.
17548 2001-11-05 Akim Demaille <akim@epita.fr>
17550 * tests/Makefile.am (testsuite): Rename this target as...
17551 ($(TESTSUITE)): this.
17554 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
17556 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
17557 the --prefix option, also remove it's argument.
17559 2001-11-05 Akim Demaille <akim@epita.fr>
17561 * doc/autoconf.texi (testsuite Invocation): Update.
17562 (Writing testsuite.at): Update.

17571 (&file_name_is_absolute): New, wrappers around routines from
17573 Use and export them.
17574 (&find_configure_ac): Optionally take a directory where to look at.
17575 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
17577 Default @ARGV to `.', not find_configure_ac.
17578 (&autoreconf): Argument is a directory.
17579 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
17580 * doc/autoconf.texi (autoreconf Invocation): Update.
17582 2001-11-03 Akim Demaille <akim@epita.fr>

17589 Don't look for aclocal flags if we already know aclocal is not
17591 Move aclocal.m4t only if it exists.
17592 Reported by Ezra Peisach.
17594 2001-11-03 Akim Demaille <akim@epita.fr>
17596 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
17597 passed on command line, defaulting to ./configure.ac if present.
17598 (&maybe_autoreconf, File::Find): Remove, unused.
17599 (&autoreconf): If autoconf is not used, don't try to trace.
17601 2001-11-02 Akim Demaille <akim@epita.fr>

17618 Don't run aclocal when aclocal.m4 is not from aclocal.
17620 Don't run libtoolize and gettextize if --install is not given.
17622 2001-11-01 Paul Eggert <eggert@twinsun.com>
17624 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
17625 be invoked before _AS_LINENO_PREPARE.
17626 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
17627 than character ranges.
17629 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
17630 invoking AS_BASENAME. Set the locale variables to 'C' if
17631 possible, as POSIX requires this to get the traditional

17638 with {}, as that triggers a bug in Bash 2.05.
17640 (_AS_LINENO_PREPARE): Use Sed rather than
17641 Awk. Fix the sed prepass to work even if there are multiple
17642 instances of $LINENO on the same line. Do not substitute for
17643 other variables like $LINENOT. Do not check file dates; such a
17644 check is unreliable on sufficiently fast machines, and removing
17645 the check makes the code simpler and more reliable. Check for
17646 output and chmod failures.
17648 * doc/autoconf.texi (Special Shell Variables): Document
17651 2001-10-31 Akim Demaille <akim@epita.fr>

17656 2001-10-31 Akim Demaille <akim@epita.fr>
17658 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
17659 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
17660 provided, while it is optional.
17661 * configure.ac: Adjust.
17663 2001-10-26 Paul Eggert <eggert@twinsun.com>
17665 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
17666 lib/Autom4te/Struct.pm:
17667 Require Perl 5.005_03 instead of just 5.005, as some tests fail
17670 * doc/autoconf.texi (Special Shell Variables): Document some
17671 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
17673 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
17674 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
17675 eval $LINENO is not portable in practice.
17677 2001-10-24 Akim Demaille <akim@epita.fr>
17679 * lib/Autom4te/General.pm (backname): New.
17681 2001-10-24 Akim Demaille <akim@epita.fr>

17691 2001-10-22 Paul Eggert <eggert@twinsun.com>
17693 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
17694 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
17695 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
17696 POSIX decided to standardize on the int flavor of strerror_r.
17697 Always do char* test, as there's no reason not to.
17698 Assign to a char* var, to catch strerror_r that returns int*.
17700 * doc/autoconf.texi (Particular Functions):
17701 Document the above changes. Also, document the fact that
17702 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
17704 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
17706 2001-10-20 Akim Demaille <akim@epita.fr>

17717 (&autoreconf): Display the full path of the configure.ac we are
17719 Trace it only once.
17720 Be sure to honor --force with gettextize.
17721 Always run aclocal.
17722 * doc/autoconf.texi: Adjust.
17724 2001-10-20 Akim Demaille <akim@epita.fr>
17726 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
17728 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
17729 `intl' is already present, as it refuses unless --force.
17730 (&parse_args): Use -I, --include instead of the old Autoconf
17732 ($localdir, $autoconf_dir): Remove.
17734 (&maybe_autoreconf): New, to preserve $_ for File::Find.
17736 2001-10-19 Jens Petersen <petersen@redhat.com>
17738 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

17757 configure.ac being studied.
17759 2001-10-18 Paul Eggert <eggert@twinsun.com>
17761 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
17762 long, to work around a bug in the HP C compiler version HP92453-01
17765 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
17766 (AS_BASENAME_EXPR): New macro.
17767 (AS_BASENAME_SED): Do not assume GNU sed semantics.
17768 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
17769 and fall back on 'sed' only if the other two fail. This makes
17770 AS_BASENAME act more like AS_DIRNAME.
17771 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
17772 contains white space.
17773 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
17774 Use AS_DIRNAME, since I think it's now DOS-friendly.
17775 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
17776 Allow "dirname //FOO" to return either / or //, as POSIX allows
17779 2001-10-10 Akim Demaille <akim@epita.fr>
17781 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

17787 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

17825 (Syntax of the shell scripts): Don't.
17826 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
17827 bother with $force since...
17828 * lib/Autom4te/General.pm: does.
17830 2001-10-08 Akim Demaille <akim@epita.fr>
17832 * bin/autoreconf.in: Rewrite in Perl.
17833 * configure.ac: Adjust.

17917 empty, and if we can find a shell that does support LINENO,
17918 then set CONFIG_SHELL to that shell and then re-execute
17919 ourselves with CONFIG_SHELL.

17923 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

18005 Check for `expr' arithmetic overflow, and for compilation failure,
18006 and invoke a new argument $4 if either is discovered.
18007 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
18008 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
18010 2001-09-28 Akim Demaille <akim@epita.fr>

18042 * tests/fortran.at (GNU Fortran 77): there.
18043 * doc/autoconf.texi (autoconf Invocation): Fix the example:
18044 AC_TRY_RUN is about compilation, not shell commands.

18058 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

18151 2001-09-22 Akim Demaille <akim@epita.fr>

18156 `$LINENO' support replacement when not supported.
18157 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

18202 arguments. Fixed a typo.
18204 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
18206 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

18224 2001-09-19 Akim Demaille <akim@epita.fr>
18226 * lib/autotest/general.m4: Englishoes.
18227 From Tim Van Holder and Alexey Mahotkin.
18229 2001-09-18 Paul Eggert <eggert@twinsun.com>
18231 * doc/autoconf.texi (Common Shell Constructs): New node,
18232 documenting AS_DIRNAME.
18233 (Limitations of Usual Tools): Refer to it when discussing dirname.
18234 Also, update discussion of POSIX standard to reflect latest draft.
18236 * lib/autoconf/c.m4:
18237 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
18239 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
18240 Do not pass a first argument with leading '-'
18241 to expr, by parenthesizing initial integers that might be negative.
18243 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
18244 now merely checks whether it is an error to pass an argument
18247 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
18248 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
18249 whether it is a (compile-time) error to pass an argument to
18250 getpgrp. This simpler test supports the revised documentation,
18251 and is all that AC_FUNC_GETPGRP's users really need.
18253 2001-09-18 Akim Demaille <akim@epita.fr>
18255 * doc/autoconf.texi (Limitations of Make) <$<>: New.

18265 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
18267 Add test for AS_BASENAME.
18268 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
18269 added test. It now correctly handles /1/2/3/, returning '3' not ''.
18270 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
18271 * tests/base.at: Fixed the expected responses. The old ones were
18273 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
18274 the documentation claims it should (and how it behaved in 2.13).
18276 2001-09-18 Akim Demaille <akim@epita.fr>
18278 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
18279 the AC_CONFIG_COMMANDS invocation.
18280 This also solves the name clash problems.
18281 Don't set the package's ID.
18282 * lib/m4sugar/Makefile.am (version.m4): Revamp.
18283 No longer to be shipped.
18284 (version.in): Remove.

18286 * lib/autoconf/status.m4: Adjust.
18287 Use `m4_PACKAGE_STRING'.
18288 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
18289 the only optional argument is the name of the test suite.
18290 Expect `package.m4' to define the package signature.
18291 * lib/autom4te.in (Autotest): Add `package.m4?'.
18292 * tests/Makefile.am (package.m4): New.
18293 * tests/suite.at: ifnames is a victim.

18297 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
18298 AC_LIBSOURCE, AC_CONFIG_FILES.
18299 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
18300 program version string doesn't match the package's.
18301 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

18312 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18313 Always include <stdio.h> and <stdlib.h>. Evaluate
18314 the expression in an extra function before these includes. Call
18315 fprintf "%d" only after ensuring the argument is of type 'int'.
18316 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
18318 2001-09-17 Paul Eggert <eggert@twinsun.com>
18320 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
18321 or CFLAGS=-O5. In that case, the linker has a relaxed view of
18322 fatal errors, and AC_CHECK_LIB causes it to include libraries even
18323 when they don't exist.
18325 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
18326 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
18329 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
18330 version with the version used by fileutils 4.1, except use
18331 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
18334 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
18336 2001-09-13 Akim Demaille <akim@epita.fr>

18376 * lib/autotest/general.m4 (AT_INIT): Create and remove
18377 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
18378 test suites can cohabit.

18382 * tests/mktests.sh: Don't output banners for empty test files.

18434 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

18437 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

18488 2001-09-05 Akim Demaille <akim@epita.fr>
18490 Be ready to handle filenames as stupid as `dnl.at', for if even
18491 the maintainer is dumb enough to do that...
18493 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
18494 excellence in M4 quotation: consider `__file__' is active.
18496 And BTW, when invoking m4, pass the --include in the right order:
18499 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

18575 2001-08-31 Akim Demaille <akim@epita.fr>
18577 * man/Makefile.am (.x.1): We really have to pass
18578 autom4te_perllibdir.

18588 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
18589 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
18590 Use directly autom4te, not autoconf.

18593 2001-08-31 Akim Demaille <akim@epita.fr>

18633 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
18634 `autoheader: `config.hin' is created'.
18635 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
18637 2001-08-31 Akim Demaille <akim@epita.fr>
18639 * bin/autoheader.in: Rewrite in Perl.

18645 Map --localdir, --autoconf-dir onto it.
18646 Forward autom4te's options instead of interpreting them.
18647 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
18648 There is no such envvar since the inception of autom4te.cfg.

18670 * lib/Autom4te/General.pm (&find_peer): Remove.
18671 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

18673 * man/Makefile.am: Let help2man rely on PATH instead of trying to
18674 find the executables for it.

18676 * tests/atlocal.in: Remove all the obscure envvar manipulations.
18678 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
18679 indeed related to running the test suite, while passing
18680 --autoconf-dir and others is related to running non installed
18681 Autoconf executables. So don't do that, leave it to...

18683 * tests/autoscan: New.
18684 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

18701 Suggested by Paul Eggert.
18703 2001-08-29 Akim Demaille <akim@epita.fr>
18705 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
18706 download in a tmp dir.
18708 2001-08-29 Akim Demaille <akim@epita.fr>

18730 foo=`(command) 2>/dev/null`

18881 the name of the directory they're in, instead of the filename,

19025 Huh!?!?! There are still some user EOF tags used, which prevents
19026 their use in AC_CONFIG_COMMANDS for instance...

19029 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

19171 * Makefile.am: Ditto (but maintainer-clean-local).
19173 2001-08-15 Akim Demaille <akim@epita.fr>
19175 * bin/autom4te.in (@m4_warning): New.
19176 (&handle_m4): Use it.
19177 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
19178 warnings are issued at each run.
19179 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
19180 is in the src tree.
19182 2001-08-15 Akim Demaille <akim@epita.fr>

19247 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
19249 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
19250 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
19251 * doc/autoconf.texi (C Compiler Characteristics): Update
19252 documentation for AC_C_BIGENDIAN.

19257 magic values from an object file when cross-compiling.
19258 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
19260 2001-08-10 Akim Demaille <akim@epita.fr>
19262 * bin/autom4te.in (&handle_output): Don't use `grep' with side
19264 Suggested by Russ Allbery.
19266 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
19268 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
19269 current $prefix to the sub-configures.
19271 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
19273 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
19274 extension (needed on BeOS). Reported by Guido van Rossum.
19276 2001-08-09 Akim Demaille <akim@epita.fr>
19278 * bin/autom4te.in ($icache): Load it only if older than autom4te.
19280 2001-08-07 Akim Demaille <akim@epita.fr>
19282 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
19284 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
19285 No need to remove the files before and after the each test, before
19286 each test and at the end of the suite is enough.
19287 Display only the children `times', not the shell's.
19288 If the test failed or was skipped, at-times is not available.
19290 2001-08-07 Akim Demaille <akim@epita.fr>
19292 Always produce testsuite.log, including when there are no
19293 failures. This helps getting information on skipped tests, and
19294 duration of the tests. Err, implement the latter btw.
19296 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
19297 Dump information on the first run of each test.
19298 (AT_CLEANUP): Create `at-times' containing the duration of the
19301 2001-08-07 Akim Demaille <akim@epita.fr>
19303 The use of `dumpstat' revealed that `len' was used although it
19304 should not. m4_text_wrap was using it, but in the Autoconf world
19305 where it is legal. Hence (i) test M4sh in its own world, not
19306 Autoconf's, and (ii), ahem, fix the bug :)
19308 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
19309 does not like `' instead of [].
19310 (AT_INIT): Forbid `^_?AT_'.
19311 And don't output such tokens.
19312 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
19313 `script.as', and `autom4te.cache'.
19314 Remove `empty' and `macro' which are no longer used.
19315 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
19316 * tests/m4sugar.at: Use it.
19317 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
19319 2001-08-07 Akim Demaille <akim@epita.fr>

19325 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
19327 2001-08-04 Akim Demaille <akim@epita.fr>
19329 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
19330 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
19332 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
19333 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
19334 (AC_F77_MAIN): Likewise.
19336 2001-08-04 Akim Demaille <akim@epita.fr>
19338 Don't rely on M4sugar outputting the patterns in files, since we
19339 might process the output _without_ running m4, hence without these
19342 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
19343 * bin/autom4te.in (@Request::includes): Remove, unused.
19344 (@Request::source): Rename as...
19345 (@Request::input): this.
19346 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
19347 (&handle_output): Fetch the patterns from the traces.

19349 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
19350 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
19352 2001-08-04 Akim Demaille <akim@epita.fr>
19354 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
19355 autoconf', i.e., in addition to caching traces, cache the output.
19357 * bin/autom4te.in (Request::cache): Rename as...
19358 (Request::id): this.
19359 ($cache, $icache, $tcache, $ocache): New.
19360 (&handle_m4): Save M4 output in the cache instead of $tmp.
19361 (&handle_output): Adjust.
19362 (&up_to_date_p): Check that the output cache is up to date too.
19363 (top level): Run `&handle_m4' iff force or the cache is invalid.
19364 Run `&handle_output' if the output cache is more recent.
19366 2001-08-04 Akim Demaille <akim@epita.fr>
19368 * bin/autom4te.in ($force): New.
19369 (&parse_args, &print_usage): -f, --force is a new option.
19370 (&handle_output): CPP directives might have spaces after `#'.
19371 (&parse_args): The first file only can be frozen.
19373 2001-08-04 Akim Demaille <akim@epita.fr>
19375 Don't let autom4te compute the `include' traces several times:
19376 first check that the trace cache file is up to date, and then
19377 compare its timestamp with that of the output.
19379 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
19380 the preamble. Don't require 5.005 as Autom4te::General does it,
19381 and better yet (use `use', not `require'!).
19382 * lib/Autom4te/Struct.pm: Rename the last occurrences of
19383 Class::Struct as Autom4te::Struct.
19384 * lib/Autom4te/General.pm (File::stat): Use it.
19385 (&mtime): New, export it.
19386 * bin/autom4te.in: Use it.
19387 Declare `$req' is invalid if it is outdated.
19388 Don't declare it valid before saving it if something went wrong.
19390 2001-08-04 Akim Demaille <akim@epita.fr>

19393 must be proposed to the users.
19395 * bin/autom4te.in (@required_trace): Remove.
19397 (&parse_args, &print_usage): -p, --preselect is a new option.
19398 (&up_to_date_p): Adjust.

19438 (m4_divert_pop): Dump the whole diversion stack when a diversion
19440 * bin/autom4te.in (&handle_output): Remember of the first
19441 occurrence of a possibly undefined macro, not the last.
19442 Complain about the possibly undefined macros in the same order as
19443 the appear in the output.
19444 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
19445 * tests/tools.at (autoconf: forbidden tokens, basic)
19446 (autoconf: forbidden tokens, exceptions): No longer sort
19447 autoconf's stderr, as it is now deterministic.
19448 Check that `dnl' is caught.
19450 2001-08-01 Akim Demaille <akim@epita.fr>
19452 * configure.ac: Bump to 2.52c.

19470 `END', as `Autom4te::General::END' will be triggered.
19471 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
19472 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
19473 system to run `mv', `rm', and `cmp'.
