4560 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
4561 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
4562 mode, we change to the source directory, also set $ac_pwd so we
4563 do not go back to the build tree for the next config subdir.

4631 (m4_require): Avoid extra macro calls.
4633 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4635 * tests/torture.at (srcdir): Fix quoting.
4637 Do not pass top_srcdir to configure scripts in testsuite.

4657 * tests/tools.at (Syntax of the shell scripts): Likewise.
4659 * tests/m4sh.at (LINENO): Quote $0.
4661 Fix testsuite program wrapper for whitespace in `pwd`.
4662 The problem here is that the usual mantra is that command
4663 variables can contain arguments, thus we cannot just escape
4664 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
4665 $top_builddir/tests directory early in $PATH, so that the
4666 wrappers are found by their plain name.
4667 * tests/wrapper.as: Put $testdir early in $PATH.
4668 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
4670 Proper config.status --file/--header and $srcdir escaping.

4681 Quote $at_group_dir.
4682 * tests/autotest.at (whitespace in absolute testdir): New test.
4684 * lib/autom4te.in: Quote @datadir@.
4686 Proper file name escaping in Autoconf programs and Perl modules.
4687 This includes escaping of characters special to the shell
4688 as well as special to Perl, e.g., leading `<' or `>'.
4689 For example, when $file starts with `>', `open ">$file"'
4690 wrongly tries to append to a different file.
4691 * bin/autoconf.as: Fix quoting for autom4te options.
4692 * lib/Autom4te/General.pm (shell_quote): New function, taken
4693 from coreutils, written by Jim Meyering.
4695 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote

4702 * tests/tools.at (autom4te and whitespace in file names): Extend
4703 test. Test twice, with special characters allowed on w32, and the
4704 rest. Test leading and trailing whitespace, for `open_quote'.
4705 (autotools and whitespace in file names): New, analogous test.
4706 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
4707 by Russ Allbery and Eric Blake.

4711 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
4712 * lib/Autom4te/FileUtils.pm (open_quote): New function.
4713 (update_file, contents): Use it.
4715 * Makefile.am (autom4te-update): Rewrite for git.
4717 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4719 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
4721 Fix copyright years.
4722 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
4723 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
4725 2007-12-04 Eric Blake <ebb9@byu.net>

4735 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
4737 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
4738 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
4739 #undef as this runs afoul of our new way of creating config.h.
4740 Problem reported by Jim Meyering in
4741 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

4745 Fix autom4te for unusual characters in input file names.
4746 * bin/autom4te.in (files_to_options): Quote active characters
4748 * tests/tools.at (autom4te and white space in file names):

4754 2007-11-24 Stepan Kasal <kasal@ucw.cz>
4756 * lib/autotest/general.m4 (AT_INIT): Do not extract the
4757 `#AT_STOP_...' line at the end of each test.
4759 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4761 * lib/autotest/general.m4 (AT_INIT): For awk line number
4762 extraction script, ensure `$at_group' has a defined value
4763 even for the empty set, and properly quote its usage inside
4766 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4768 * doc/autoconf.texi (Shell Functions): New chapter. Document
4769 IRIX sh $0 issue in functions, move content from ...
4770 (Portable Shell): ... here.
4771 (Shell Script Compiler): Note that shell functions are not
4772 totally unportable any more.

4785 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4787 Fix IRIX testsuite debugging failures: $0 in functions.
4788 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
4789 Do not use $0 inside a function, as IRIX sh will set that to the
4790 function name rather than the script invocation name.
4792 2007-11-19 Paolo Bonzini <bonzini@gnu.org>

4797 (AT_INIT): Extract and cache test script line numbers.
4799 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4801 * lib/autotest/general.m4: Revert 2007-11-15 patch and
4802 subsequent fixups; the awk -> here-document conversion trashes
4803 performance too much with AIX sh.
4805 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4807 * tests/local.at: Do not test m4, perl with AT_TESTED.
4809 Diagnose and guard against write errors dealing with config.status.
4810 The general idea is this: all write failures from `configure'
4811 writing `config.status' are indicated by $ac_write_error, which
4812 is only checked at the end. This is safe because config.status
4813 code is not executed before the file is complete. Other write
4814 failures, be they inside config.status, or in sub shell/awk
4815 scripts spawned from configure or config.status, typically need
4816 earlier checking, as their results are used right afterwards.
4817 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
4818 before writing config.status, check afterwards.
4819 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
4820 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
4821 Set `ac_write_error' for write failures to config.status. Barf
4822 upon write failures to temporary files.
4823 Adjust note about closing and reopening the here-document.
4824 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
4825 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
4826 reopening the here-document.
4827 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4828 Ensure `ac_write_error' does not escape into config.status.
4829 Also, add a couple of code paths not yet exercised in the test
4830 suite: a config file with input from stdin, and a config header
4832 Suggestion for catching write errors by Bruno Haible.
4834 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4836 Avoid error with Tru64 awk and testsuite lines with many words.
4837 * lib/autotest/general.m4 (AT_INIT): In the awk script that
4838 reads the testsuite, set the field separator to an unusual value,
4839 in order to not run over the limit of 199 fields. Tru64 4.0D awk
4840 even splits the input if $i, i>0, was never accessed in the script.
4842 Revert 2007-10-17 change.
4843 * TODO: Multiline args in config files and headers mean something
4844 different and are not fixed, see

4956 them. Before, with a parallel build, these rules could lead to
4957 two processes writing tests/wrapper.in concurrently.
4959 Build in man/ only *after* building in bin/ and tests/.
4960 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
4961 in both bin/ and tests/.
4963 Accommodate non-srcdir build-from-checkout.
4964 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
4965 Use git's --git-dir=$srcdir/.git option.
4966 Add quotes, in case tarball_version_file contains shell meta-characters.
4967 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
4968 * configure.ac: Pass "." to git-version-gen.
4970 Avoid spurious test failures due to version skew.
4971 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
4973 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4975 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
4976 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
4977 Remove conftest.dSYM directory.
4978 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
4979 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
4980 Remove `conftest.*' recursively.
4981 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
4982 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4984 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
4986 Report and analysis by Jeff Squyres and Peter O'Gorman.

4990 Fix typos in variable names.
4991 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
4993 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
4995 Document that $((expression)) is not portable.

4998 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5000 Ignore configure --help* errors due to LINENO-impaired shells.
5001 * tests/torture.at (Configuring subdirectories, Deep Package):
5002 In the --help* tests in read-only trees, make `.' temporarily
5003 writable again for the `stderr' file, and ignore errors due to
5004 the attempt to write configure.lineno.
5005 Report by Patrick Welche.
5007 2007-11-10 Jim Meyering <meyering@redhat.com>
5009 Generate package.m4 in build-dir, not srcdir.
5010 * tests/Makefile.am (package.m4): Adjust target.
5011 Don't redirect directly to $@.
5012 (CLEANFILES): Add package.m4.
5013 ($(TESTSUITE)): Depend on just-built package.m4, not the one
5015 When running $(AUTOTEST), search "." before searching $(srcdir).
5017 Avoid a race condition that would make parallel "distclean" fail.
5018 * tests/Makefile.am (distclean-generic): Replace the default,
5019 automake-provided rule with an identical one, but with an additional
5020 dependency on distclean-local. Simply adding the dependency would
5021 cause automake not to emit the rule at all.
5022 * BUGS: Building with -jN works, now.
5024 Distribute git-version-gen.
5025 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
5026 since GNUmakefile is distributed, and requires it for dist* rules.
5028 Remove two more generated files from version control.
5029 * INSTALL: Remove generated file.
5030 * lib/autoscan/autoscan.list: Remove generated file.
5032 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
5034 * GNUmakefile (PATH): Remove stray apostrophes; they become
5035 part of PATH, which isn't wanted here.
5037 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5039 New config files output variable `top_build_prefix'.
5040 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
5042 * doc/autoconf.texi (Preset Output Variables): Document it.
5044 Report by Bob Friesenhahn.
5046 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
5047 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
5048 function, to parametrize arithmetic with expr vs. the shell.
5049 Use it where possible.
5050 Suggestion by Benoit Sigoure.
5052 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
5054 Adjust the documentation of autotest WRT atlocal.
5055 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
5056 when using Automake, to write a rule to produce atlocal, since it's
5057 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
5058 distributed, not atconfig.in.
5060 2007-11-04 Eric Blake <ebb9@byu.net>
5062 Update list information.
5063 * README: Mention new autoconf-commit list.

5070 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
5072 * build-aux/.gitignore: Ignore mkinstalldirs.
5074 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
5076 2007-11-03 Jim Meyering <meyering@redhat.com>
5078 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
5079 * build-aux/git-version-gen: This syncs from coreutils.
5081 Adjust the build procedure so "make check" works reliably.
5082 * README-hacking: Include an extra step between "make" and
5083 "make check" to ensure that the latter passes.
5085 Use just-built tools, when possible.
5086 * GNUmakefile (PATH): Set and export here, ...
5087 (dummy): ... rather than here.
5089 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5090 and Andreas Schwab <schwab@suse.de>
5092 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
5095 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5097 * configure.ac (AC_PREREQ): Require version 2.60, for
5098 AC_PROG_SED, AC_PROG_GREP.

5110 2007-11-03 Eric Blake <ebb9@byu.net>
5112 Support m4 1.4.5 in testsuite.
5113 * tests/torture.at (Define a newline): Exclude line numbers in
5115 Reported by Ralf Wildenhues.
5117 2007-11-03 Jim Meyering <meyering@redhat.com>
5119 Remove automake-provided files from version control.
5120 * build-aux/elisp-comp: Remove file.
5121 * build-aux/install-sh: Remove file.
5122 * build-aux/missing: Remove file.
5123 * build-aux/mdate-sh: Remove file.
5124 * build-aux/.gitignore: New file.
5125 Suggestion from Ralf Wildenhues.
5127 2007-11-03 Eric Blake <ebb9@byu.net>
5129 Adjust version comparison to account for git snapshot numbers.
5130 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a

5133 <m4_version_compare>: Document this change.
5134 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
5136 2007-10-30 Bruno Haible <bruno@clisp.org>
5138 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
5139 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
5140 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
5141 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
5142 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
5143 Suggested by Paul Eggert.
5145 2007-10-28 Jim Meyering <meyering@redhat.com>
5147 * README-hacking: Autoconf, Automake, and Perl are required to build.
5148 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
5150 2007-10-28 Jim Meyering <meyering@redhat.com>
5152 README-hacking: Recommend running autoreconf -vi.
5153 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
5154 so that we use just-built tools when they're available.
5155 Suggestions from Ralf Wildenhues.
5157 2007-10-28 Jim Meyering <meyering@redhat.com>
5159 Make inter-release --version output more useful.
5161 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
5162 which indicates that it is built using the 19th change set
5163 (in _some_ repository) following the "v2.61a" tag, and that 58dd
5164 is a prefix of the commit SHA1.
5165 * build-aux/git-version-gen: New file.
5166 * configure.ac: Run it to set the version.
5167 (AM_INIT_AUTOMAKE): Don't check NEWS here.
5168 * Makefile.am (dist-hook): Arrange so that .version appears only
5169 in distribution tarballs, never in a checked-out repository.
5170 * .gitignore: Add .version here, too. Just in case.
5171 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
5172 not configure.ac, now that the version number changes automatically.
5174 Ensure that $(VERSION) is up to date for dist-related targets.
5175 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
5176 git-version-gen doesn't match $(VERSION), but only for dist targets.
5178 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5207 and Eric Blake <ebb9@byu.net>
5209 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
5210 problem reported by Bruno Haible in
5211 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.

5215 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
5218 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
5220 Don't check for bug in HP-UX 11.00 cpp.
5221 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
5222 Use -1ull rather than -1u, since that causes problems with gnulib; see
5223 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

5241 escaping of backslash in here-documents.
5243 Fix `Deep Package' test failure on FreeBSD.
5244 * tests/torture.at (Deep Package): Do not add `.' to $PATH
5245 unnecessarily. Do not try running `/bin/sh configure' with a
5246 configure script to be found in $PATH, if the shell does not do
5247 this resolution. Fixes test failure on FreeBSD.
5249 Fix config header generation with AIX awk.
5250 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
5251 script, use helper array D_is_set, as `" 0"' does not evaluate
5252 to true for AIX awk.

5290 (TESTS_END): Diversion no longer used.
5291 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
5292 shell function, which prints only as needed, using an associative
5293 array of banner text from a special diversion.
5294 <PARSE_ARGS_END>: No longer need awk to find banners.
5295 <TESTS>: Banners are no longer processed by main driver loop, so
5296 we no longer need case statement.
5297 (AT_BANNER): Rewrite to populate new diversion.
5298 (AT_SETUP): Each test invokes its own banner. No output is needed
5299 to the TESTS diversion.

5328 programs with stdin redirected, so programs that don't
5329 understand --version won't try to behave interactively.
5330 * tests/autotest.at (Tested programs): Catch this bug.
5331 * tests/m4sugar.at (m4@&t@_append): Test new macro.

5391 is not writable, use 'cp -p' in this case, in the hope that it
5392 will not actually be needed. Still try removing files, in case
5393 of other write errors.
5394 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): For ac_confdir,
5395 use $as_myself, not $0.
5396 (_AC_INIT_HELP): For --help=recursive, if the subdir does not
5397 exist, try again in the the source tree. This change assumes
5398 that the subpackage configure script is capable of running
5399 --help=recursive in the source tree.

6438 2007-04-26 Paul Eggert <eggert@cs.ucla.edu>
6440 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
6441 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
6444 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
6446 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
6447 AC_CHECK_TYPE, AC_CHECK_TYPES.
6448 * doc/autoconf.texi (Generic types): C types must be type-names
6449 (the C terminology), not type-ids (the C++ term). C++ types
6450 must not be anonymous.
6451 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
6452 for C++; this drops support for anonymous struct and union types,
6453 which were problematic anyway.
6454 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
6457 2007-04-12 Jim Meyering <jim@meyering.net>
6459 * doc/autoconf.texi (Libraries): Typo fix: insert missing "in".
6461 2007-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6463 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK): Fix AC_CONFIG_LINKS
6464 to prefer a link source from the build tree, if it exists.
6465 Report by Pallav Gupta <pallavgupta@gmail.com>.
6467 2007-04-11 Paul Eggert <eggert@cs.ucla.edu>
6469 * doc/autoconf.texi (Generic Types): Document the restrictions
6470 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
6471 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
6472 with objects too. Document the restrictions on its use.
6473 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
6474 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
6475 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
6476 works but the latter doesn't, then it's a valid type.
6477 This lets people use function types and so forth.
6478 For C++ there doesn't seem to be a simple solution, so leave it alone.
6479 (AC_CHECK_SIZEOF): Allow argument to be a variable.
6480 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
6481 AC_CHECK_TYPE; that wasn't documented or necessary.
6483 2007-04-11 Stepan Kasal <kasal@ucw.cz>
6485 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
6486 when cross-compiling.
6488 2007-04-11 Stepan Kasal <kasal@ucw.cz>
6490 * doc/autoconf.texi (External Software): Fix a typo in the

6498 2007-04-06 Paul Eggert <eggert@cs.ucla.edu>
6500 * doc/autoconf.texi (Particular Types): AC_C_LONG_DOUBLE is now
6501 obsolescent. Suggested by Bruno Haible.
6502 * NEWS: Document this.
6504 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
6506 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
6507 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
6508 default still has the problem. Problem reported by Bruce Korb.
6510 2007-03-28 Stepan Kasal <kasal@ucw.cz>
6511 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6513 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix a

6523 command and case statements to make it a bit clearer and describe
6526 2007-03-23 Paul Eggert <eggert@cs.ucla.edu>
6528 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
6529 checks for unsigned long long int.
6531 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
6533 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
6534 nonstandard grep R.E. escape sequences.
6536 2007-03-17 Jim Meyering <jim@meyering.net>
6538 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
6539 (Limitations of Usual Tools): Also list \< and \>, and mention that
6540 HP-UX's grep, like the one from Solaris, does not support that syntax.
6542 2007-03-09 Stepan Kasal <kasal@ucw.cz>
6544 * doc/autoconf.texi (Specifying Names): `--host' does not
6545 change the build type.
6547 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
6549 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
6550 suggests AC_CONFIG_HEADERS.
6551 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using
6552 AC_CONFIG_HEADERS. Problem reported by

6559 http://lists.gnu.org/archive/html/autoconf-patches/2007-02/msg00024.html
6560 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
6561 universal binaries. Problem reported by Elias Pipping.
6563 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
6565 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
6566 * doc/autoconf.texi (C Compiler): Document this. There is a new
6567 extra argument ACTION-IF-UNIVERSAL.
6568 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
6569 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
6570 Reindent for sanity's sake.
6572 2007-02-24 Eric Blake <ebb9@byu.net>
6574 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
6576 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.

6580 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6582 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
6583 status of rm so we know when it failed.
6584 If cleaning of test dir failed before running the test, warn.
6585 Output the line separator in verbose mode before the warning
6586 to make clear the warning belongs to the following test.
6588 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
6590 * doc/autoconf.texi (Parentheses): Mention problem with (( in

6597 errors introduced in last change.
6599 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
6601 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
6602 an actual carriage return. Use "ac_cr" to contain the actual

6613 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
6614 input from /dev/null in awk test, so even Solaris /usr/bin/awk
6615 will not wait for input with a script containing only a BEGIN

6642 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
6644 (Shell Substitutions): Note problems with @{var:=value} etc.
6645 Add a new section for problems with @{#var} etc. Problem noted

6649 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6651 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
6652 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
6653 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
6654 substitution will still be done by the special code.
6655 Report by Jim Meyering.
6657 * doc/autoconf.texi (File System Conventions): Mention that
6658 $PATH_SEPARATOR is for the build system only.
6659 Report by Keith Marshall.

6669 Test all 8 bit non-NUL characters.
6670 Report against Automake by Patrick Welche.
6672 2007-01-15 Stepan Kasal <kasal@ucw.cz>
6674 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
6676 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6678 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
6679 early on the reader side, drop stderr of the input to avoid
6680 `broken pipe' error output; this may happen even with shell
6681 builtin `echo' of some bash versions. Reports by Ian Macdonald
6682 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
6684 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6686 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

6697 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
6698 * doc/autoconf.texi (Signed Overflow Examples): Give more
6699 discussion about the allow_superuser_privileges example,
6700 and change it a bit to make things clearer.
6701 (Optimization and Wraparound): Clarify whether the compiler
6702 will generate an infinite loop for the example derived from
6703 Autoconf's mktime test.
6704 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
6705 Also, clarify unsigned multiplication overflow.
6707 2007-01-04 Eric Blake <ebb9@byu.net>
6709 * bin/Makefile.am (RELEASE_YEAR): New macro.
6710 (edit): Use it to supply correct copyright year to scripts.
6711 * bin/autoconf.as (version): Use it.
6712 * bin/autoheader.in ($version): Likewise.
6713 * bin/autom4te.in ($version): Likewise.
6714 * bin/autoreconf.in ($version): Likewise.
6715 * bin/autoscan.in ($version): Likewise.
6716 * bin/autoupdate.in ($version): Likewise.
6717 * bin/ifnames.in ($version): Likewise.
6719 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
6721 * doc/autoconf.texi (Integer Overflow): Revised based on today's
6722 feedback. The most important changes document what happens when
6723 you convert an out-of-range value to a signed integer type, and
6724 say that (sum < a) != (b < 0) reliably detects overflow when sum =
6727 * doc/autoconf.texi (Integer Overflow): Greatly expand and
6728 rewrite, taking notions from the recent discussion on the gcc and
6729 autoconf mailing lists; please see
6730 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
6731 and follow the many links.
6732 (Integer Overflow Basics, Signed Overflow Examples):
6733 (Optimization and Wraparound, Signed Overflow Advice):
6734 (Signed Integer Division): New sections.
6736 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
6738 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
6739 preprocessor macro arguments in traced name.
6740 * doc/autoconf.texi (Defining symbols): Document longstanding
6741 support for AC_DEFINE-ing macros with arguments, and document
6742 behavior when the same variable has multiple AC_DEFINEs.
6743 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
6744 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
6745 macros directly, giving much shorter and simpler code.
6747 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
6749 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
6750 space before "$ac_configure_args" to prevent a 'config.status
6751 --recheck' failure if ac_configure_args doesn't contain a leading
6752 space. This works around a problem with the XEmacs configure.ac,
6753 which uses the (undocumented) ac_configure_args variable
6754 inconsistently with Autoconf.
6756 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
6758 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
6759 Include <limits.h>, and use its INT_MAX to rewrite the
6760 j loop so that it does not overflow 'int'. Problem reported by
6762 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
6763 Play it safe by shifting left by 1 rather than multiplying by 2,
6764 as GCC is less likely to optimize this away when the value
6765 is signed (when it assumes overflow leads to undefined behavior).
6766 Also, don't assume time_t uses two's complement.
6768 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6770 * tests/torture.at (Substitute a 2000-byte string): Avoid using
6771 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
6772 dumps core on it. Report by Tim Rice.
6774 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
6776 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
6777 --disable-option-checking to --help output even when
6778 AC_PRESERVE_HELP_ORDER is not used.
6779 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
6780 --with argument, rather than argument with [-.] replaced by
6782 * NEWS: Fix typo in previous change; the news was in the
6785 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
6787 * NEWS: Warnings are now generated by default for unknown
6788 --enable-* and --with-* options.
6789 * doc/autoconf.texi (Option Checking): Renamed from
6790 (Configure Option Checking). Tighten up the wording a bit.
6791 (External Software, Package Options): Cross-reference to Option
6792 Checking, and use this to shorten our section.
6793 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
6794 "$x" to test "x$foo" != x.
6795 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
6796 Don't warn if $enable_option_checking is "no".
6797 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
6798 ac_unrecognized_opts to the empty string.
6799 Don't echo the unrecognized opts, as this might mishandle
6800 backslashes or leading -.
6801 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
6802 usage next to the other --disable-FEATURE options in the
6805 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
6807 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
6808 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
6809 Print warning for unrecognized --with and --enable options
6810 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
6811 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
6812 Disable option checking when subdirs are configured.
6813 (AC_OUTPUT): If warnings are enabled, print warning about
6814 unrecognized --with and --enable options at the end of
6815 the configure output (as well as at the beginning).
6816 * doc/autoconf.texi (Option Checking): New node.
6817 Document new option warning functionality.
6819 2006-12-16 Eric Blake <ebb9@byu.net>
6821 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
6822 * NEWS: Start news for current version.
6824 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
6826 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6827 Define HAVE_GETMNTENT to 1, not to the empty string.
6828 Problem originally reported by Jochen Friedrich in
6829 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
6831 This change prompted by a problem report by Andrey Simonenko in
6832 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
6833 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
6834 object-like macros only, in the traditional portable character
6836 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
6837 Warn about attempts to define things that are not identifiers.
6838 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
6839 awful hack that AC_DEFINEd macro names containing parentheses.
6841 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
6843 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
6844 too drastic, even if Texinfo in theory requires it for info mode.
6846 (config.status Invocation): Renamed back from Recreating a
6848 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
6849 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
6851 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6853 * NEWS: Version 2.61a.
6855 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6856 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6858 * NEWS: Document changes with echo and printf, and the lack
6859 of limits on the total size of multi-line values of substituted
6860 variables, and the AC_FUNC_FSEEKO fix.
6862 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
6864 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
6865 Writing configure.ac.
6866 (Autoconf Input Layout): Renamed from configure.ac Layout.
6867 (Recreating a Configuration): Renamed from config.status Invocation.
6868 (Obsolete Recreation): Renamed from Obsolete config.status Use.
6869 (acconfig Header): Renamed from acconfig.h.
6870 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
6871 (Writing Testsuites): Renamed from Writing testsuite.at.
6872 (Autom4te Cache): Renamed from autom4te.cache.
6874 * BUGS: Remove mention of VPATH problem, since it's now documented
6875 not to be a bug in the Autoconf build procedure itself, but rather
6876 a problem with the proprietary `make' programs.
6878 * doc/autoconf.texi (Build Directories): Add a cross reference
6881 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
6882 * doc/standards.texi: Sync from gnulib.
6884 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
6885 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:

6887 generated automatically.
6889 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
6891 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
6892 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
6893 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
6895 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6897 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
6898 `CEOF$ac_eof' special marker, the awk script cannot contain a
6899 line matching `^CEOF', so this is not needed any more.
6900 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
6901 special marker in the test.
6903 2006-12-06 Stepan Kasal <kasal@ucw.cz>
6905 * tests/tools.at (autom4te preselections): Use `find -newer';
6906 remove one of the sleeps.
6908 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
6909 more readable, using ...
6910 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
6912 * doc/autoconf.texi (autoheader Invocation): Do not double-
6913 quote the parameter of `AH_BOTTOM' in the example.
6915 2006-12-05 Stepan Kasal <kasal@ucw.cz>
6917 * doc/autoconf.texi (Configuration Headers): Remove the
6918 example with multiple input files.
6919 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
6920 multiple input files.
6922 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6924 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
6925 creating the awk substitution script, handle one input line at a
6926 time, so that the maximum length of a substituted (multi-line)
6927 value is not limited by the size of the sed pattern space.
6928 The trade-off is a slightly repetitive sed script.
6929 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
6930 can only have up to 7 characters, due to Solaris 10 /bin/sed.
6931 * tests/torture.at (Substitute a 2000-byte string): Increase the
6932 test with several long lines, they should not be caught by sed
6935 * tests/tools.at (autom4te preselections): New test, to flag
6936 entries missing from autom4te.cfg.
6937 Report by David Byron <dbyron@hheld.com>.
6939 * tests/torture.at (Substitute a 2000-byte string): Actually use
6940 AC_PROG_AWK, so the last change works as intended.
6941 (Substitute and define special characters): Likewise.
6942 (Substitute a newline): Likewise.
6944 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
6945 instead of `awk' consistently.
6946 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
6947 * tests/torture.at (Torturing config.status): Test both the
6948 result of AC_PROG_AWK and plain awk.
6949 (Substitute a 2000-byte string): Likewise.
6950 (Substitute and define special characters): Likewise.
6951 (Substitute a newline): Likewise.
6953 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
6955 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
6956 can be assigned to a function pointer. Problem reported by
6957 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
6958 part of a patch by Ralf Wildenhues in that same bug report.
6960 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
6962 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
6963 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
6965 2006-12-01 Eric Blake <ebb9@byu.net>
6967 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
6968 cross-compiling from cygwin to mingw.
6969 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
6970 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
6971 to lib/autoconf/c.m4.
6973 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6975 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
6976 string for more reliable failure. Wrap the entire test that
6977 causes the broken Solaris printf to dump core, in a subshell,
6978 so the segmentation fault message is reliably suppressed.
6979 Fix shell expansion errors by using /usr/ucb/echo always;
6980 avoid an error on systems without it by another subshell.
6981 Avoid m4 expansion of `$1'. Set the zeroth argument of the
6982 subshell-$as_echo to `as_echo', for better error message.
6984 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6986 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
6987 `BASH_SOURCE' contain a newline, set them to empty, as they may
6990 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
6992 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
6993 years and is too hard to maintain now. The last straw was
6994 reported by Jerker Baeck in
6995 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
6996 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
6997 * doc/autoconf.texi (Particular Functions): Move
6998 AC_FUNC_SETVBUF_REVERSED from here...
6999 (Obsolete Macros): ... to here. Say that it does nothing now.
7000 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7001 Turn into (almost) a no-op.
7003 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
7005 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
7006 These macros are obsolescent and new applications shouldn't need them.

7014 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
7016 * doc/autoconf.texi (Setting Output Variables): Mention that
7017 @VAR1@VAR2 has unspecified behavior. Problem reported by
7019 * NEWS: Mention this.
7021 * Makefile.am: Put only a single '#' into the copyright notice,
7022 so that it's also present in the output file. Standardize wording
7023 in makefile copyright notices to match GNU coding standards.
7024 * bin/Makefile.am: Likewise.

7037 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7039 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
7040 in the sed script that mangles the awk script: delete up to the
7041 first exclamation mark only.
7042 * tests/torture.at (Substitute and define special characters):
7045 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7047 Rewrite config files generation: avoid quadratic growth in
7048 the number of substituted variables by using awk instead of sed
7049 for the bulk of the substitutions.
7050 * NEWS: Mention this.
7051 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
7052 forbidden in the output (and thus input) file.
7053 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
7054 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
7055 generate just one large awk script for substitutions,
7056 eliminating much of the earlier complexity, while adding some
7057 new complexity. Only expand the substitution templates at
7058 configure time, for smaller configure script size. If
7059 _AC_SUBST_FILES are used, test 'awk' for working getline support
7060 at config.status time. If absent, interpolate through the
7061 shell. The awk script was written with much help
7062 from Paolo Bonzini and Paul Eggert.
7063 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
7064 (_AC_SED_FRAG_NUM): Likewise.
7065 (_AC_SUBST_CMDS): Renamed from...
7066 (_AC_SED_CMDS): ...this.
7067 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
7068 * tests/torture.at (Substitute a 2000-byte string): Also
7069 substitute a line with 1000 words, and a variable with several
7071 (Substitute and define special characters): Test awk special
7072 characters, and put substitution input strings `@foo@' in the
7073 output, to test that no recursion happens; test several other
7074 combinations from Paolo Bonzini.
7076 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
7078 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
7079 that replaced echo with AS_ECHO where this wasn't necessary.
7080 Problem reportd by Ralf Wildenhues.
7081 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
7082 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
7083 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
7085 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7087 * lib/freeze.mk (GREP): Removed, no need to initialize this.
7089 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
7091 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
7092 that traditional Awk lacks 3-arg "split". It has it.
7093 Mention that FS must be a single character, and a few other
7094 99-byte limits of traditional Awk.
7095 Mention that if (i in a) doesn't work with traditional Awk.
7097 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
7099 * tests/autotest.at (BSx641-newline in command):
7100 (BS-BS-newline in command, BSx640-newline in command):
7101 (Newline-CODE-BS-newline in command):
7102 (Single-quote-BS-newline in command):
7103 (Single-quote-newline-BS-newline in command):
7104 Use printf '%s\n' instead of echo, for portability to hosts
7105 where echo interprets backslashes. This will break on hosts
7106 that lack printf, but for now let's assume all such hosts
7107 are dead (if not, we should get reports of test failures).
7109 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
7111 'echo' has some portability problems, when given a first argument
7112 with a leading '-', or when given any argument containing '\'.
7113 Avoid using 'echo' in these cases.
7114 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

7142 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
7143 Don't use ECHO_T, since ECHO_N is now reliable.
7144 * lib/autotest/general.m4 (AT_INIT): Likewise.
7145 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
7146 rather than using a here-document to put the script into a file.
7147 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
7149 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
7150 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
7151 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
7152 bug, but we might as well stop using ECHO_N and ECHO_C internally.
7153 * lib/autotest/general.m4 (AT_SETUP): Likewise.

7155 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

7157 operand, as AS_ECHO requires. Avoid double file name expansion.
7158 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
7159 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
7160 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
7161 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
7162 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
7163 Double-quote strings that would otherwise contain M4 comments.
7164 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
7166 * configure.ac (AC_INIT): Bump to 2.61a.
7169 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
7173 * configure.ac (AC_INIT): Bump to 2.61.
7176 * tests/autotest.at (Macro with backslash in a test title):
7177 Comment out for now, as this tests neither fails nor passes
7178 reliably. Problem reported by Ralf Wildenhues.

7195 Import these changes from config via gnulib:
7197 2006-11-15 Ben Elliston <bje@gnu.org>
7199 From Josselin Mouette <joss@debian.org>:

7270 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
7271 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
7272 Imported from a similar patch to gnulib by Bruno Haible.
7274 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
7276 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

7293 and Stepan Kasal <kasal@ucw.cz>
7295 Handle special characters in test case titles correctly.
7296 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
7298 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
7299 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
7300 argument. Extend to check titles printed by ./micro-suite and
7301 ./micro-suite -l and the title in micro-suite.log.
7302 (Backquote in a test title,
7303 Single-quote in a test title,
7304 Double-quote in a test title): Don't expect failure anymore.
7305 (Backslash in a test title): Put a non-whitespace character after the
7306 backslash so that Bourne shells might actually see it as an escape
7308 (Brackets in a test title,
7309 Pound in a test title,
7310 Comma in a test title,

7318 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
7319 The visible effect was a stray [] in the testsuite output.
7321 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7323 * doc/autoconf.texi (Limitations of Builtins): Do not invoke

7326 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
7328 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
7329 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
7330 5363) simply issues a warning when dividing by zero at compile
7331 time. Problem reported by Elias Pipping.
7333 2006-10-26 Eric Blake <ebb9@byu.net>
7336 * doc/autoconf.texi (Evaluation Macros): Improve the example to
7337 show effect on macros that expand with commas.

7365 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
7366 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
7367 reported by Nelson H. F. Beebe for Coreutils 6.4.
7369 * tests/tools.at (autoconf --trace: user macros): Remove test
7370 for tracing multiline macros, since m4 1.4.7a uses a different
7371 way to number lines. Problem reported by Ralf Wildenhues.
7373 2006-10-24 Stepan Kasal <kasal@ucw.cz>
7375 * bin/autom4te.in (handle_m4): Do not redirect stdin to

7401 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
7402 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

7449 (Imported from Automake.)
7450 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
7451 which incorrectly sets the mode of an existing destination
7452 directory. In some cases the unpatched install-sh could do the
7453 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
7454 system. We hope this is rare in practice, but it's clearly worth
7455 fixing. Problem reported by Alex Unleashed in
7456 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
7457 Also, don't bother to check for -m bugs unless we're using -m;
7458 suggested by Stepan Kasal.

7507 added to the template can get mangled.
7509 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7511 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
7512 include the default headers, and redefine obstack_chunk_alloc
7513 and obstack_chunk_free. Fixes false failure with glibc.

7530 the NonStop platform.
7531 * doc/autoconf.texi (Posix Variants): Likewise.
7532 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
7534 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
7535 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
7536 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
7537 Use a better substitute, by inspecting the output of "ls"
7538 rather than just using ":".
7539 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
7540 rather than AS_EXECUTABLE_P, since we needn't worry about
7541 non-regular files here.
7543 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
7544 due to configuration hassles with this. See Tonya Underwood's report
7545 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

7557 initialization which is not inherited through the environment
7558 (_AS_BOURNE_COMPATIBLE): ... to this new macro.

7564 problems with mkdir -p -m.
7566 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
7568 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
7569 comment about ac_cpp_err; it was incorrect, and anyway
7570 ac_cpp_err is being removed below.
7571 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
7572 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
7573 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
7575 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
7576 with werror_flag and conftest.err and so forth. This is more
7577 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
7578 and anyway the user shouldn't normally want to see this gorp logged.
7579 Problem reported by Ralf Wildenhues.
7580 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
7581 empty, not 'no', since the rest of the code uses 'test -z'.

7585 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
7586 Use a single call to AC_DO_TOKENS rather than multiple, for
7588 (_AC_LINK_IFELSE): Test that resulting file is executable.
7589 Problem reported by mwoehlke in
7590 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
7592 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
7593 than creating a file to use with test -x; this is much faster.
7595 2006-10-02 Bruno Haible <bruno@clisp.org>
7597 * lib/autom4te.in (Automake-preselections): Add
7598 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
7600 2006-09-27 Stepan Kasal <kasal@ucw.cz>
7602 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
7603 standard error, `experr' should be used, not `expout'.
7605 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
7607 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
7608 fseeko testing program twice; just use the earlier result.
7609 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7610 Set cache var to 'unknown' (not 'no') if leaving the macro unset
7611 still doesn't let the program compile.
7612 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
7615 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
7616 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
7617 include it, without including anything else.
7618 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
7620 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

7624 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
7625 `error.h', and include it, for a `error_at_line' prototype.
7626 Use a nonempty format string in the link test.
7627 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
7628 for a declaration of wait3.

7633 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
7634 can apply to constants too, and that it checks for macro defns.
7635 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
7636 and simply cast the identifier to void. This handles structure
7637 values. Problem reported by Ralf Wildenhues.

7799 except the first two arguments are reversed.

7850 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
7851 didn't work if some values were cached but not others. Test for
7852 broken lex libraries like native ia64-hp-hpux11.22; see
7853 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
7854 work around the problem by preferring an empty LEXLIB to -lfl or
7855 -ll. Let the user set LEXLIB='' to indicate no library needed.

7982 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
7983 -Wundef -Werror". Problem reported by David Fang in
7984 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

8004 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
8006 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
8007 problems with arg script text that doesn't end in newline, and

8026 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
8028 Fix test suite failures reported by Pierre in
8029 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
8030 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
8031 the compiler created a file "b.out" when it didn't create anything
8033 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):

8044 less skeptical about "volatile", after discussion with
8045 Bruno Haible on bug-gnulib.
8046 (Limitations of Usual Tools): Warn about sed stripping
8047 leading white space from text. From Bruno Haible.

8056 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
8057 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
8059 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
8061 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
8062 after -R regardless of host. Patrick Welche reports that this
8063 fixes things on NetBSD 3.99.

8073 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
8074 under AC_C_VOLATILE.
8075 (Volatile Objects): Be a little less skeptical about what
8076 "volatile" means. Derived from thoughts by Ben Pfaff in
8077 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
8079 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8083 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
8085 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
8086 more globally, since the 2006-06-30 patch didn't suffice. Problem
8087 reported by Keith Marshall. Also, don't bother with builddir2,
8088 since it shouldn't be needed any more.
8090 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
8092 * doc/autoconf.texi (Generic compiler characteristics):
8093 Document AC_COMPUTE_INT. Fix wrong statements on Default
8094 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.

8107 * NEWS: Document previous change.
8109 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
8111 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
8112 Require that long long int be at least 64 bits wide. C99 requires
8113 this and enough programs depend on it so we should check for it.
8114 Bruno Haible reports in
8115 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
8116 that long long int is 32 bits wide with some nonstandard compilers.
8117 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.

8121 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
8122 to a nonexistent file, so that we don't have to worry about
8123 a local site configuration that doesn't use /usr/local.
8124 Problem reported by Keith Marshall in
8125 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
8127 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
8129 * doc/autoconf.texi: Be more consistent about using @acronym with
8130 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
8131 quite right (it talked about "OSF/Tru64", even though the
8132 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
8133 and it even mentioned "OSF 4"!) and at this point there's little
8134 reason to talk about OSF any more, since it died in 1994.
8135 (Specific Compiler Characteristics): Simplify example of
8136 negative-size array.
8137 (File Descriptors): Reorder to make the text flow better.
8138 Remove joke about "appreciate the various levels"; I didn't get it.
8139 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
8140 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
8141 (File Descriptors, Limitations of Usual Tools):
8142 Tone down the advice against renaming or removing open files.
8143 (Limitations of Usual Tools): Add a new section, on 'rm'.
8145 2006-06-26 Stepan Kasal <kasal@ucw.cz>
8147 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
8148 -lXt in LIBS, idea from Karsten Hopp; this was due since
8151 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
8152 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
8153 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
8154 (which belong to Xt, not X itself). See Debian bug 327655.
8156 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8158 * configure.ac (AC_INIT): Bump to 2.60a.
8161 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8165 * configure.ac, NEWS: Update.

8172 quadrigraph correctly in traces.
8174 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
8177 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
8178 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
8180 * doc/autoconf.texi (Changed Directory Variables): New node,
8181 to document the whole `datarootdir' business a bit better.
8183 * tests/torture.at (datarootdir workaround): Extend test.
8184 Prompted by report by Alexandre Julliard.
8186 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
8188 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
8189 when using default mode of IBM C 6 for AIX. Problem and two-line
8190 fix reported by Larry Jones.
8192 2006-06-22 Alexandre Julliard <julliard@winehq.org>
8194 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
8195 about literal '${datarootdir}' if a definition is found in the
8198 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
8200 * NEWS: Use "M4" rather than "m4" when appropriate.
8201 Problem reported by Eric Blake.
8202 * doc/autoconf.texi: Likewise.
8203 Use @acronym around BSD, GCC, and GNU when appropriate.
8204 (Why GNU M4): Renamed from "Why GNU m4".
8205 (Redefined M4 Macros): Mention that Posix
8206 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
8207 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
8210 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8212 * bin/autom4te.in (handle_output): Do not forbid the empty
8214 * tests/tools.at (autoconf: the empty token): New test.
8216 2006-06-20 Stepan Kasal <kasal@ucw.cz>
8218 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
8219 calls, so that we do not care whether they are LIFO or FIFO;
8220 in the m4_wrap, do not check which diversion is the topmost
8221 one, just check that the stack is balanced at the end.
8222 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
8223 base diversion forever--pop the previous diversion before
8224 opening the new one; consequently, remove the m4_wrap call.
8225 * lib/autotest/general.m4 (AT_INIT): Likewise.
8226 * tests/m4sugar.at: Do not use
8227 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
8229 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
8230 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8232 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
8233 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
8234 Rework example of m4wrap token-pasting trouble so that it doesn't
8235 care whether it's LIFO or FIFO.
8236 Fix some "contrary to"s that are awkward in English.
8238 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8240 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
8241 to `yes' instead of `int$1_t' if the type is found, for more
8242 consistent configure output (where $1 is the number of bits).
8243 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
8244 Suggested by Bruno Haible.
8246 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
8247 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
8248 with system headers. Report by Bruno Haible.
8250 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8252 * config/config.guess, config/config.sub: Sync from upstream.
8254 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
8255 in order to avoid picking up an older installed frozen m4sh.m4f.
8256 Besides an outdated shell startup, this could have been created
8257 by an earlier M4 version with incompatible frozen file format.
8259 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
8261 * README: Recommend m4 1.4.4 instead of 1.4.3..
8262 * doc/autoconf.texi: Likewise.

8264 suggested by Stepan Kasal.
8265 (Installation Directory Variables, Build Directories):
8266 (Automatic Remaking, Subdirectories, Fortran Compiler):
8267 (Making testsuite Scripts, Defining Directories):
8268 Quote variable usages better.
8269 (Making testsuite Scripts): Add clean-local rule to makefile
8270 snippet, by Eric Blake.
8271 (Installation Directory Variables): Fix table item font.
8272 Reword slightly to clarify. Generalize advice about
8273 not using special characters to include all file-related
8274 vars, not just VPATH.
8275 (Special Chars in Variables): Warn about special characters in
8277 (Assignments): Clarify default-value example as suggested by
8279 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
8280 (Special Shell Variables): Note leading ./ or ../, as suggested
8282 (Limitations of Builtins): Under cd, warn about CDPATH.
8283 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
8286 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8288 * doc/autoconf.texi (Configuration Actions): Remove duplicate
8289 `@var', for texi2html.
8290 (Systemology): Some more word wrapping, for DVI output.
8291 (autom4te Invocation): The short option for `--melt' is `-M',
8294 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
8296 * doc/autoconf.texi: More formatting and English tweaks,
8297 many suggested by Ralf Wildenhues.
8298 Reword to avoid "@code{...}'s" and the like, since it's ugly
8299 with Emacs info mode. discontents -> woes.
8300 Put a few "will"s back. time stamp -> timestamp.
8301 side-effect -> side effect.
8303 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
8305 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
8306 Warn about $@ not persisting. Problem reported by Julien Danjou in
8307 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
8308 (Special Chars in Names): Renamed from Leading _ in Macro Names.
8309 Mention other special chars, too.
8311 2006-06-14 Eric Blake <ebb9@byu.net>
8313 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
8315 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
8317 * doc/autoconf.texi: Some systematic minor improvements, as
8318 follows. Use "makefile" when talking about makefiles
8319 generally (which might be named "makefile" or "Makefile" or even
8320 "foo.mk"), "Makefile" when talking about a specific makefile
8321 called "Makefile". This unclutters the text from weird quotes
8322 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
8323 values" rather than "@var{foo}s" and similar constructs containing
8324 "}s". Use "Make rules" rather than "Makefile rules". Minor
8325 English-language improvements. Change the prefix "sub-" to "sub"
8327 Put blank lines around examples more consistently.
8328 Avoid "rather" and "very" as intensifiers.
8329 Avoid "will" as an auxiliary.
8330 (Limitations of Make): Split this node into....
8331 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
8332 (Leading _ in Macro Names, Backslash-Newline-Newline):
8333 (Backslash-Newline Comments, Long Lines in Makefiles):
8334 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
8335 (obj/ and Make, make -k Status, VPATH and Make):
8336 (VPATH and Double-colon, $< in Explicit Rules):
8337 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
8338 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
8339 New nodes, resulting from splitup of Limitations of Make.
8340 All cross-references changed. Raise the top node from
8341 a section to a chapter, and all subnodes accordingly.
8342 Redo the introductory wording to match the new organization.
8343 (Installation Directory Variables): Use an example that is
8344 closer to what Autoconf actually does. Mention that VPATH's
8345 value should not contain metacharacters or white space.
8346 (Fortran Compiler): Fix a VPATH bug in an example.
8347 (Leading _ in Macro Names): Mention that this problem is no longer
8348 of practical concern.
8349 (VPATH and Make): Reword the advice to make it clearer
8350 that Autoconf and Automake support VPATH in non-GNU make, but
8351 many packages have bugs in this area.
8352 ($< in Explicit Rules): Refer to Build Directories rather
8353 than using a (non-VPATH-safe) example.
8354 (Automatic Rule Rewriting): Mention the sort of disaster that
8355 can ensue with Solaris-style rule rewriting with VPATH.
8357 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8359 * doc/install.texi (Compilers and Options): Weaken the
8360 suggestion to use GNU make for VPATH builds.
8362 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
8363 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
8365 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
8366 in regular expression.
8368 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8370 * doc/autoconf.texi (Installation Directory Variables):
8371 Drop extra @samp from `@table @samp' item.
8372 (Limitations of Usual Tools): Comment fix.
8373 Do not nest @samp just to point to other table items.
8374 (Writing testsuite.at) <AT_CHECK>: The second argument to
8375 `@dvar' is already @samp'ed.
8376 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
8377 do not use @var in the second argument.
8379 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
8381 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
8382 $as_shell.exe too. Problem reported by Andreas Buening in
8383 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
8385 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8387 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
8388 `unused variable' compiler warning, for `-Wall -Werror'.
8389 Reported by Jaap Haitsma in
8390 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
8392 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
8394 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
8395 case the compiler dumps core. Problem reported for
8396 OpenServer 5.0.7 by Tim Rice in
8397 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
8398 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
8401 2006-06-06 Tim Rice <tim@multitalents.net>.
8403 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
8404 "ERROR" only shows up in "make check" output if there is an
8407 2006-06-06 Eric Blake <ebb9@byu.net>
8409 * tests/tools.at (automatically allowed tokens): Fix typo.
8411 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8413 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
8415 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
8416 typically overflows on x86 CPUs, even though the C standard
8419 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8421 * configure.ac (AC_INIT): Bump to 2.59e.
8424 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8428 * config/texinfo.tex: Sync from upstream.
8430 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
8431 seen, invoke libtoolize with `--ltdl' argument.
8432 * lib/autom4te.in (Autoreconf-preselections): Adjust.
8434 Suggested by Eric Blake.
8436 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8438 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
8439 reported by Ralf Wildenhues.
8440 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
8442 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8446 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8448 * doc/autoconf.texi: Modernize some of the references to Solaris.
8450 2006-06-05 Stepan Kasal <kasal@ucw.cz>
8452 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
8453 message issued by AC_REQUIRE.
8454 * tests/m4sugar.at: Check m4_require's error message.
8455 * tests/base.at: Check AC_REQUIRE's error message.
8456 * tests/local.at (AT_CHECK_M4): New macro, almost identical
8458 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
8460 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
8461 `expout' as the last parameter.
8462 * tests/tools.at: Adapt to the above change.
8464 2006-06-04 Stepan Kasal <kasal@ucw.cz>
8466 * doc/autoconf.texi (Limitations of Usual Tools): Correct
8467 information about race-free implementations of mkdir.
8469 2006-06-04 Eric Blake <ebb9@byu.net>
8471 * bin/autoreconf.in (help): Document M4 environment variable.
8472 * bin/autoconf.as (Usage): Likewise.
8473 * bin/autom4te.in (help): Likewise.
8474 * doc/autoconf.texi (autom4te Invocation): Likewise.
8476 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
8478 * NEWS: GNU make now recommended for VPATH builds.
8479 Mention that some macros are now documented to be obsolescent.
8480 * doc/autoconf.texi:
8481 Prefer "current" to "modern" to describe
8482 currently-used (albeit perhaps old-fashioned) hosts.
8483 Mention which ancient features no longer need to be worried about.
8484 setgid -> set-group-ID
8485 setuid -> set-user-ID (these are the Posix terms)
8486 Fix some misuses of "only".
8487 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
8488 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
8489 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
8490 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

8495 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
8496 Mention that these macros are obsolescent.
8497 (Installation Directory Variables): shall -> should
8498 (File Descriptors): Mention that 0, 1, 2 might get reopened.
8499 Mention that it's now safe to use 3 and 4.
8500 (Limitations of Usual Tools): cp -r is now specified by Posix.
8501 Omit longwinded and obsolescent discussion of cp -f.
8502 Modernize discussion of expr, ls.
8503 (Limitations of Make): Modernize discussion of VPATH builds.
8504 Mention $? as a workaround in some cases.
8505 * doc/install.texi (Basic Installation):
8506 Mention "./configure; make; make install" first. Be more
8507 specific about why this file is generic. Remove unnecessary
8508 parens. Remove misleading "only". Remove obsolete advice
8509 about csh. Don't say "configure" takes awhile; say it
8510 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
8511 and CC=c99 rather than CC=c89, as these are blessed by current
8512 Posix. Recommend GNU make if doing a VPATH build.
8514 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
8516 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
8517 examples involving shell prompts.
8519 2006-06-02 Stepan Kasal <kasal@ucw.cz>
8520 and Paul Eggert <eggert@cs.ucla.edu>
8522 * doc/autoconf.texi (Here-Documents): Add details about the
8523 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
8524 use "here-documents" instead of "here documents".
8526 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8528 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
8530 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
8532 * doc/autoconf.texi (File System Conventions): Warn about ":"
8533 anywhere in directory names.
8535 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
8537 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
8538 about quoting the case statement, just in case.
8539 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
8540 was fixed in ksh93g; reported by Ralf Wildenhues.
8542 2006-05-31 Stepan Kasal <kasal@ucw.cz>
8544 * doc/autoconf.texi (System Services): Do not document
8545 overriding EXEEXT via ac_cv_exeext=ext.
8546 (Particular Programs) <AC_PROG_MKDIR_P>:
8547 Document that ${MKDIR_P} understands --.

8551 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8553 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
8554 argument with leading hyphen. Problem reported by Paul Eggert.
8556 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
8558 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
8559 about quoting ac_try: quote all of it, if any of it seems suspicious.
8560 This means we don't have to worry about ${ or sed any more.
8561 Also, double-quote the case statement, to work around misuses via
8562 underquoting as reported by Ralf Wildenhues in
8563 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
8564 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
8565 undocumented and dangerous macro.
8566 Problem reported by Ralf Wildenhues in
8567 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
8569 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8577 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
8578 since evidently some packages rely on the old, broken behavior.
8579 Problem reported by Ralf Wildenhues in
8580 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
8581 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
8582 pre-2006-05-26 definitions, but leave in the comments that
8583 these macros are dangerous and should not be used.
8584 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
8585 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
8586 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
8587 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
8588 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
8590 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
8592 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
8593 the use of 'tr', since this is our only use of 'tr'.
8595 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8596 and Paul Eggert <eggert@cs.ucla.edu>
8598 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
8599 Don't assume 'grep' works on long lines, since AIX grep doesn't.
8601 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8603 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
8604 the output file in the `${datarootdir}' test.
8606 2005-05-28 Stepan Kasal <kasal@ucw.cz>
8607 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8609 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
8610 mention of `datarootdir' in the input file(s), but literal
8611 `${datarootdir}' in the output file, and we haven't warned yet,
8612 then warn as well: the user may have (erroneously) used
8613 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
8614 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
8615 * tests/torture.at (datarootdir workaround): Extend this test.
8618 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8619 and Paul Eggert <eggert@cs.ucla.edu>
8621 * doc/autoconf.texi (autoheader Invocation): The first argument to
8622 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
8623 alternatives and clear up the language a bit.
8625 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
8627 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
8628 ac_config_guess, ac_config_sub, ac_configure.
8629 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8630 Fix typo that prevented an unnecessary space from being removed.
8631 Problems reported by Ralf Wildenhues in:
8632 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
8634 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
8636 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
8637 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
8638 Don't use the term "thread-safe" to talk about mkdir race
8639 conditions, since the problem is more a process than a thread
8640 issue. Problem reported by Stepan Kasal in:
8641 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
8642 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
8643 the test for 'install' more closely. Look at MKDIR_P first.
8644 Look in the PATH, and at /opt/sfw/bin.
8645 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
8646 Don't bother to try mkdir -p, since we already check mkdir --version;
8647 just look at the version number. (There's no easy way to check
8648 for race-free implementations.)
8649 * tests/tools.at (autoconf: subdirectories): Adjust to above
8650 changes, since MKDIR_P now might end in "/mkdir -p".
8652 * doc/autoconf.texi (autoheader Invocation): Mention that the
8653 first arg of AC_DEFINE_UNQUOTED must be a literal.
8654 Problem reported by Ben Pfaff in
8655 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
8657 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
8658 * doc/autoconf.texi (Special Chars in Variables): New section.
8659 (Preset Output Variables): Warn about special chars in CPPFLAGS.
8660 (Installation Directory Variables): Quote $(datadir) better.
8661 (Limitations of Builtins): Describe some of eval's trickiness.
8663 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
8664 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
8665 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
8666 in front of every arg, not just trailing args. Quote apostrophes.
8667 (_AC_EVAL_ECHO): New macro.
8668 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
8669 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
8671 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
8672 exposed by quoting of eval argument. Put the command on line line
8674 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
8675 (_AC_PATH_X, AC_PATH_X): Quote more safely.
8676 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
8677 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
8678 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
8679 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
8680 Use eval more safely.
8681 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
8682 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
8684 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
8685 lines, exposed by quoting of eval argument.
8687 2006-05-26 Stepan Kasal <kasal@ucw.cz>
8688 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8690 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
8691 initialization of `ac_cv_exeext', do not override it if it was
8692 already set, unless it was set to `no', for compatibility with
8693 Autoconf-2.13, and comment this.
8694 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
8695 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
8696 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
8697 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
8698 Document that this test may be overridden by setting
8701 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8703 Revert these two patches:
8705 2006-04-06 Eric Blake <ebb9@byu.net>
8706 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
8707 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
8710 2006-04-01 Stepan Kasal <kasal@ucw.cz>
8711 Clean up _AC_COMPILER_EXEEXT* macros.
8712 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
8713 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
8714 ac_file to the name of the default output file and call
8715 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
8716 initial `rm' of the candidate files...
8717 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
8718 the same list in subsequent `rm' calls, and for the temporary
8719 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
8720 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
8721 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
8722 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
8723 no longer needed) by libtool. Make it a cache check.
8724 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
8725 copied here by mistake.
8726 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
8727 _AC_COMPILER_EXEEXT.
8728 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
8729 _AC_COMPILER_OBJEXT directly.
8730 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8732 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8734 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
8735 Fix description of how the buggy `sed' works.
8737 2006-05-25 Noah Misch <noah@cs.caltech.edu>
8741 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
8742 ENOLCK. Only mention `make -j' when applicable. Only raise
8743 fatal errors when `make -j' is involved. Improve error message.
8745 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8747 * doc/autoconf.texi (Here-Documents): We now know more about
8748 the variable expansion in here documents bug.
8749 Thanks to Tim Rice and Stepan Kasal.
8751 * doc/autoconf.texi (Making testsuite Scripts): Add an example
8752 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
8754 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8756 * tests/autotest.at (Multiline command from M4 expansion):
8757 No failure to be expected if the shell quotes newlines in
8758 commands in the `set -x' output. Report by Tim Rice.
8761 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8763 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
8764 expansion in the here-documents used by config.status, as that
8765 runs afoul of the Korn shell version M-12/28/93d bug described in
8766 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
8767 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
8768 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
8770 2006-05-23 Jim Meyering <jim@meyering.net>
8772 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
8773 Fix typo introduced with 2006-04-02 change. It reversed the sense
8776 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8778 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
8779 ac_dB slightly, to save bytes in the script.
8780 Max out at 50 lines, rather than 96; this is more likely
8781 (though not guaranteed) to avoid obscure 'sed' failures.
8783 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8785 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
8786 `tr -d -' as bad option argument. Work around this by deleting
8787 an unrelated character.
8788 Report by Tim Rice <tim@multitalents.net>.
8790 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
8791 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
8792 Stepan Kasal <kasal@ucw.cz>
8794 * doc/autoconf.texi (Particular Programs): Do not promise that
8795 we always prefer the GNU version of the program, and that we
8796 search according to PATH; both rules can have exceptions.
8797 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
8798 AC_PROG_SED. Move descriptions of limitations
8799 to the Limitations of Usual Tools section.
8800 (Limitations of Usual Tools) <sed>: Mention script length
8801 limitations with Solaris /usr/ucb/sed.
8802 <grep>: Fix wording for empty alternative. Mention that -c and
8803 -l should not be combined, and that -E and -F should not be
8806 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8807 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8809 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
8810 limits in Solaris 8 /usr/ucb/sed by testing a long script.
8812 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8814 * doc/autoconf.texi (Defining Symbols): Literal parameter of
8815 AC_DEFINE is now passed to m4_pattern_allow.
8816 * NEWS: Mention that; likewise for AC_SUBST.
8817 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
8818 the parameter to m4_pattern_allow.
8819 * tests/tools.at: Add a check for that.
8821 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8823 * lib/autoconf/status.m4: Fix typos.
8825 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8827 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
8828 only the files that this macro generates.
8830 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8832 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
8833 the HP-UX sed limitation of 99 commands, labels do not count.
8834 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
8836 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
8838 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8840 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8841 Import the following fix from coreutils:
8843 2006-01-13 Jim Meyering <jim@meyering.net>
8845 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
8846 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
8847 not double-quote uses of that variable, to accommodate the rare
8848 case in which getmntent is available in none of the libraries
8849 checked. This happens at least on FreeBSD 5.0.
8851 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
8853 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
8854 ac_config_guess, ac_config_sub, and ac_configure, since evidently
8855 some other programs unwisely rely on these undocumented vars.
8856 But put in warning comments about them.
8857 Problem reported by Ralf Wildenhues in
8858 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
8859 * NEWS: Document that these variables are intended to go away.
8861 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8863 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
8864 and set the language to C++ (analogous to the equivalent Fortran
8867 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
8868 * doc/autoconf.texi (C++ Compiler): Document it.
8869 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
8872 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
8874 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
8875 that caused config.status to generate 100-command sed scripts; the
8876 portable limit is 99.
8878 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8880 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
8881 variable `ac_d' instead of `d' to avoid infringing namespace.
8882 Report by Ralf Menzel.
8884 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
8886 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
8887 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
8888 * tests/tools.at (autoconf: subdirectories): New test, taken from
8889 the corresponding problem report by Ralf Wildenhues in:
8890 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
8892 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
8893 Quote some uses of shell variables if they might suffer unexpected
8894 globbing. This doesn't fix all instances of quoting problems that
8895 I found, just the easy ones that look safe.
8896 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
8897 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
8898 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
8899 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
8900 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
8901 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
8902 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
8904 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
8905 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
8907 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8909 * bin/autoreconf.in ($help): Reword according to the manual.
8910 Suggested by Olly Betts.
8912 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
8913 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8915 * bin/autoreconf.in: Pass the directory argument to
8916 `require_configure_ac'. Fix comment.
8917 * tests/torture.at (Configuring subdirectories): Expose this.
8918 Reported by Olly Betts.
8920 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8922 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
8923 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
8924 Automake as follows:
8926 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
8927 `$configure_in' instead of `configure.in', to preserve
8928 directory component.
8930 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8932 * config/config.guess, config/config.sub, config/texinfo.tex,
8933 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
8935 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
8937 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
8938 test for C99 conformance; (bool) 0.5 is an integer constant
8939 expression, but (bool) -0.5 is not. Problem reported by Fedor
8940 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
8942 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
8944 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
8945 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
8946 Warn about obsolete install-sh files. Remove stray sentence
8947 fragment and fix cross reference.
8948 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
8949 install -d; this undoes the 2006-05-10 change.
8950 (MKDIR_P): Mark with AN_MAKEVAR.
8951 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
8952 that we don't require $INSTALL to be thread-safe. Move comments
8953 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
8954 of AC_PROG_INSTALL. Output a message saying that we're checking
8955 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
8956 MKDIR_P instead of AC_SUBST.
8957 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
8958 Special magic for MKDIR_P, too.
8959 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
8961 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
8963 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
8965 Sync from Automake, as follows:
8967 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8968 * config/install-sh: Initialize IFS, so field splitting isn't
8970 * config/mkinstalldirs: Likewise.
8971 * config/missing: Remove superfluous quotes. Replace all uses of
8972 `[' by `test', for consistency, and for..
8973 * config/missing (sed_minuso, sed_output): New variables.
8974 (autom4te, help2man, makeinfo): Use them. Unifies detection of
8975 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
8976 Fixes `missing' to detect `--output' for help2man. Fixes
8977 PR automake/483. Report by Dennis J. Linse.
8978 (autom4te): Document in `missing --help'.
8980 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8982 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
8983 * config/install-sh: Don't use 'path' to talk about file names,
8984 as per GNU coding standards. Close a race condition reported by Ralf
8985 Wildenhues and Stepan Kasal. There is still a race condition
8986 on hosts that predate Posix 1003.1-1992, but we can't help this.
8987 Don't mishandle weird characters like space on pre-Posix hosts.
8988 Invoke mkdir at most once per dir arg on pre-Posix hosts.
8989 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
8990 AC_PROG_MKDIR_P from AS_MKDIR_P.
8991 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
8992 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
8993 earlier editions are not (including Automake 1.8.3).
8994 Do not suggest mkinstalldirs for thread-safety.
8995 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
8996 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
8997 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
8998 presence of special characters and race conditions.
8999 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
9000 in Autoconf's name space.
9002 2006-05-10 Bruno Haible <bruno@clisp.org>
9003 and Paul Eggert <eggert@cs.ucla.edu>

9009 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9011 * config/install-sh: Update to Automake CVS version, as follows:
9012 2006-04-25 Stepan Kasal <kasal@ucw.cz>
9013 * lib/install-sh: Simplify the expr implementation of dirname.
9014 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
9015 * lib/install-sh: Handle --, and diagnose unknown options.
9017 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9019 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
9020 `./autom4te' to create `./testsuite', since the `all' target
9021 will ensure its presence, but `installcheck' should not create
9022 the uninstalled wrappers.
9024 * tests/torture.at (Unusual Automake input files): Skip if we
9025 detect automake < 1.8.
9027 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9029 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
9030 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
9031 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
9034 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9036 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
9037 munge (multiple) white space and other oddities.
9038 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
9039 single quotes in variable assignment.
9040 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
9041 and similar failures by adding multiple spaces, tabs, and other
9043 Report and different test suggested by Francesco Romani
9044 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
9046 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
9047 single quotes, we only need to search for single quotes; this
9048 both simplifies the search pattern, and makes us less
9049 susceptible to `echo' variations for arguments not containing
9051 (_AC_ARG_VAR_VALIDATE): Likewise.
9053 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9055 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
9056 `$*' and IFS concatenation issue with traditional shells and
9057 bash-2.04. Report by Seanster@Seanster.com.
9059 2006-05-03 Bruno Haible <bruno@clisp.org>
9061 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
9062 precisely which Mac OS X versions have the od problem.
9064 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
9066 * doc/autoconf.texi: Use @option systematically.
9068 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
9069 and Bruno Haible <bruno@clisp.org>
9071 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
9073 (Integer Overflow): Mention the special case of integer division
9076 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9078 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
9079 traditional shells like the Solaris one that do not use the
9080 first IFS character for assembling `$*'.
9081 Prompted by a related report from autoconf_bug@nro.ca.
9083 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
9084 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9087 Mention more problems with the -e option.
9089 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9092 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
9094 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
9095 in URLs to improve DVI formatted output (requires texinfo 4.6).
9096 (System Services, Systemology, Shellology): Likewise.
9097 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
9100 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
9102 (Runtime): Fix macro argument names to match description:
9103 `action-if-found' -> `action-if-true' and similarly.
9104 (Obsolete Macros): Likewise.
9105 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.

9107 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
9109 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9111 * doc/autoconf.texi (Limitations of Make): Clean up markup.

9141 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
9142 since as_me isn't set yet.
9144 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
9146 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
9147 a few minor bugs in this area.
9149 * doc/autoconf.texi (Programming in M4sh): Comment out the
9150 documentation of AS_BASENAME, for now.

9191 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
9192 newline from the `trap' code to finish `config.log'; the NetBSD
9193 /bin/sh resets the exit status after an empty command, as
9194 documented in doc/autoconf.texi.
9195 Reported by Dalibor Topic <robilad@kaffe.org>.
9197 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
9199 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
9200 Suggested by Bruno Haible.
9202 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
9204 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
9205 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
9206 Instead, just list the shells that we know work.
9207 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
9208 changed. Be more cautious about the _cv_ variable.
9209 * tests/tools.at (Syntax of the shell scripts): Check the
9210 _cv_ variable once, at first, to avoid an internal autoconf error
9211 when sh -n does not work.
9213 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9215 * lib/Autom4te/FileUtils.pm: Sync from Automake.
9217 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
9219 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
9220 use ">&-" since we're only 99.999% sure that this is portable,
9221 and since the MinGW bug is fixed in a different way.
9222 * lib/autotest/general.m4 (AT_INIT): Likewise.
9224 2006-04-16 Stepan Kasal <kasal@ucw.cz>
9226 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
9227 before opening config.log, to avoid hitting a bug on MinGW.
9229 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
9231 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
9232 AS_MESSAGE_LOG_FD before reopening it onto the log file.
9233 This works around a MinGW bug reported by Eric Paire.
9234 Make sure that all writes to the log file append to it,
9235 rather than possibly losing data.
9236 * lib/autotest/general.m4 (AT_INIT): Likewise.
9238 2006-04-14 Stepan Kasal <kasal@ucw.cz>
9240 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
9243 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9247 * configure.ac (AC_INIT): Bump to 2.59d.
9249 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9253 * Makefile.maint (news-date-check): Do not require a leading `*'
9254 before the release date in NEWS.
9256 2006-04-12 Stepan Kasal <kasal@ucw.cz>
9257 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9259 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
9260 the instantiated file do not contain the string 'datarootdir'
9261 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
9262 @mandir@, replace the reference '${datarootdir}' by the value.
9263 * tests/torture.at (datarootdir workaround): New test.
9264 * NEWS: Advertise this temporary fixup.
9265 Based on a patch by Bruno Haible, reported and analyzed by
9266 Paul Eggert and Noah Misch.
9268 2006-04-12 Eric Blake <ebb9@byu.net>
9270 * tests/autotest.at (Debugging a failed test): Fix comment.
9272 2006-04-12 Stepan Kasal <kasal@ucw.cz>
9274 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
9275 all the changes since 2006-04-07.
9277 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9279 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
9280 succeeded, but `ln -s file dir' failed, take care to remove the
9281 leftover target before the next test, to prevent its spurious
9282 failure; also make sure `ln file dir' works before selecting it.
9283 Thanks to Keith Marshall for pointing this out.
9286 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
9287 assignments in `at_debug_args', so that we put them correctly
9288 in the `run' script.
9289 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
9290 Reported by Eric Blake.
9292 2006-04-11 Eric Blake <ebb9@byu.net>
9294 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
9295 top-level tests after micro-suite has been run. Used in...
9296 (Debugging a successful test, Debugging script and environment),
9297 (Debugging a failed test): ...these new tests. The first of these
9299 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
9300 macro, split out from...
9301 (AT_INIT): ...here, so that using -d also generates a run script.
9302 Document that -d inhibits top-level logging.
9303 * doc/autoconf.texi (testsuite Invocation): Document that -d only
9304 inhibits top-level logging; debug scripts are created.
9306 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
9308 * tests/autotest.at (Empty test, Empty check): New test to check it.
9310 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
9313 2006-04-10 Stepan Kasal <kasal@ucw.cz>
9315 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
9316 the files if a problem appears. Make the empty *.at files
9317 read-only, too. Proposed by Ralf Wildenhues.
9319 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9321 * config/Makefile.am: Add comment to force updated Makefile.in.
9323 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
9324 space only patch to this file, this patch causes the Makefile.in
9325 files that include freeze.mk to be updated, and thus have a
9326 newer time stamp again, which in turn makes a pristine CVS
9327 checkout have correct time stamps.
9329 * Makefile.maint (cvs-sv): New macro, to be used..
9330 (config.guess-url_prefix, config.sub-url_prefix)
9331 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
9332 point to CVS text checkout of Gnulib files.
9333 (copyright-check): Bump current year.
9334 (announcement): Do not hard-wire `./announce-gen'.
9335 (cvs-update): Propagate failures of `cvs' and `move-if-change'
9337 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
9339 (wget_files): Update config.guess, config.sub, texinfo.tex by
9340 `wget-update', now that their URLs work again.
9342 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
9344 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
9345 Problem noted by Paul D. Smith.
9347 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9349 * doc/autoconf.texi: Remove unused words from word list.
9350 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
9351 .x-sc_trailing_space: New files.
9353 * doc/standards.texi: Sync from gnulib.
9355 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
9356 `LIBOBJDIR' as experimental.
9358 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
9359 with a target directory; it's internally implemented as `cp'
9360 anyway, but since Autoconf advertises the possibility to use
9361 a target directory when LN_S is `ln -s', we need to find out.
9362 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
9363 analyzed by Keith Marshall <keith.marshall@total.com>.
9367 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
9369 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
9370 confdefs.h as-is. In general, if it has backslash-newline or the
9371 like, then it doesn't work either to sort or to remove empty
9374 2006-04-09 Stepan Kasal <kasal@ucw.cz>
9376 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
9378 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
9380 * lib/autom4te.in (Automake-preselections): Preselect
9383 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
9385 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
9386 apostrophe within a single-quoted string, as this is the usual
9387 tradition and is easier to read than '"'"'. Don't rely on the
9388 shell treating "$/" like '$/'. Use a more-consistent indenting
9391 2006-04-09 Eric Blake <ebb9@byu.net>
9393 * tests/autotest.at (Backquote command substitution),
9394 (Multiline backquote command substitution): Remove mistaken
9395 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
9397 (Parenthetical command substitution, Multiline parenthetical
9398 command substitution): here.
9400 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

9433 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
9434 (C Compiler): Move AC_C_LONG_DOUBLE to ...
9435 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention

9460 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
9462 2006-04-08 Stepan Kasal <kasal@ucw.cz>
9464 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
9465 of the warning introduced by the 2001-08-28 change.

9475 2006-04-07 Stepan Kasal <kasal@ucw.cz>
9477 Revert the patch from 2006-04-01 and only improve
9478 _AS_DETECT_BETTER_SHELL:
9480 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
9481 skip nonexistent directories.
9482 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
9483 only shell candidates which exist.
9484 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
9485 * lib/autotest/general.m4 (AT_INIT): No need to give three
9486 parameters to _AS_PATH_WALK.
9488 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
9489 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9491 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
9492 distinguish m4sugar macros.
9493 * tests/tools.at (autoupdating with aclocal and m4_include):
9494 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
9495 test case by Noah Misch <noah@cs.caltech.edu>.
9497 2006-04-07 Stepan Kasal <kasal@ucw.cz>
9499 Revert my change from 2006-03-17, in other words:

9508 * doc/autoconf.texi (Programming in M4sh): Document that
9509 AS_MKDIR_P exits the script on failure.
9510 * lib/autotest/general.m4: Remove redundant AS_ERROR.
9512 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9514 * config/elisp-comp, config/install-sh, config/mdate-sh,

9531 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9533 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
9534 whether `set' quotes correctly: redirect stderr of the tested
9535 `set', and use a subshell, for Ultrix; use `sed' instead of
9536 `grep' for zsh `set' which may write binary output; match only
9537 at the beginning of a line, to avoid false positives.
9538 In order to avoid false positives by unrelated variables with
9539 multiline content, put the dump algorithm in a subshell and
9540 unset all variables containing newlines (except some which are
9541 special to the shell). Warn about cache variables that are
9544 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9546 * config/config.guess, config/config.sub, config/texinfo.tex:
9549 * tests/mktests.sh: Reword comments.

9555 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
9556 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
9557 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
9558 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
9560 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
9561 shell issue with double-quoted command substitutions of native
9563 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith

9581 2006-04-06 Stepan Kasal <kasal@ucw.cz>
9583 * tests/Makefile.am (maintainer-check-posix):
9584 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
9586 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
9587 ac_config_<foo>s again, sometimes normalized, sometimes not.
9588 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
9589 (AC_CONFIG_COMMANDS): Do not do so here.
9590 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
9591 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
9592 2005-07-25 rewrite. Noticed by Noah Misch.
9594 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
9595 _AC_PRESERVE_HELP_ORDER, ...
9596 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
9598 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
9599 inside m4_expand_once; it is redundant.

9602 for --help from Cygnus `configure.'
9604 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

9615 Noah Misch <noah@cs.caltech.edu>
9617 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
9618 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
9619 * doc/autoconf.texi (Help Formatting): New node.
9620 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
9622 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9624 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,

9643 TAGS to ac_config_<foo>s.
9644 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.

9646 normalizing it, consistent it with previous releases.

9659 whereby substrings were incorrectly matched, causing us to not
9660 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
9661 (exclude_list): Exclude empty macros.
9662 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

10574 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10576 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10577 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10578 (which belong to Xt, not X itself). See Debian bug 327655.
10579 * NEWS: Mention this.
10581 2005-09-07 Stepan Kasal <kasal@ucw.cz>
10583 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
10585 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
10587 * config/move-if-change: Don't output "$2 is unchanged";
10588 suggested by Ben Elliston. Handle weird characters correctly.
10590 2005-09-06 Stepan Kasal <kasal@ucw.cz>
10592 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
10593 calls, so that the final expansion of this macro is shorter.
10594 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
10595 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
10596 the cleanup there. Use AS_VAR_* macros, to be more general.
10597 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
10599 * lib/autoconf/general.m4: Use AS_IF where appropriate.
10601 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
10603 2005-09-01 Stepan Kasal <kasal@ucw.cz>
10605 * doc/autoconf.texi (Configuration Headers): Add an index entry
10608 2005-08-26 Pavel Roskin <proski@gnu.org>
10610 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
10611 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
10614 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
10616 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
10617 The previous patch didn't work, so try a better one.
10619 2005-08-26 Stepan Kasal <kasal@ucw.cz>
10621 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
10622 in the example. Reported by Bruno Haible.
10623 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
10624 "if $undefined_var;" succeeds with my shell.
10626 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
10627 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
10628 but change the m4_divert_text to m4_divert_once.
10630 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
10632 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
10633 Work around bug in Solaris /usr/xpg4/bin/awk.
10634 The bug is present in at least Solaris 8 through 10.
10636 2005-08-24 Stepan Kasal <kasal@ucw.cz>
10638 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
10639 some evil values and relying on the fact that $* concatenates the
10640 parameters by the first character from IFS.
10642 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10643 Stepan Kasal <kasal@ucw.cz>
10645 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
10646 first header appears, define AH_HEADER.
10647 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
10648 Update limitations about when to call AC_CONFIG_HEADERS.
10649 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
10650 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
10651 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
10652 ``Configuration Actions''; fix their index entries.
10654 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
10655 options correctly. Process N-M as M-N if M is smaller than N.
10656 Process ranges correctly so that N-N will run only N.
10657 Sort and uniquify the tests that will be run. If there is more
10658 than one test, reinsert the banners for the tests.
10659 * tests/autotest.at (Keywords): Unmark XFAIL.
10661 2005-08-23 Stepan Kasal <kasal@ucw.cz>
10663 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
10664 before passing the macro name to AH_TEMPLATE.
10666 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
10667 now opens log after option processing; in particular, --version
10668 and --help do not touch config.log.
10670 * Makefile.maint: Revert the change from 2005-08-12.
10672 2005-08-22 Stepan Kasal <kasal@ucw.cz>
10674 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
10676 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.

10680 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
10681 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
10684 * doc/autoconf.texi (Defining Symbols, Changed Results):
10685 Prepend to LIBS, not append, in examples.
10687 2005-08-16 Stepan Kasal <kasal@ucw.cz>
10689 When building in place, set srcdir="."; suggested by Tim Van Holder.
10691 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
10692 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
10693 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
10694 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
10695 does not mean "no --srcdir option".
10697 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10699 * tests/autoscan.at (autoscan): New file.
10700 * tests/suite.at: Use it.
10701 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
10702 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
10704 * tests/autotest.at (Keywords): Test keywords combinations.
10706 2005-08-12 Stepan Kasal <kasal@ucw.cz>
10708 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
10709 add "2>&1"; gzip 1.2.4 prints help on stderr.
10711 2005-07-27 Stepan Kasal <kasal@ucw.cz>
10713 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
10714 was pushdef'ed twice while popped only once. Push it only once.
10715 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
10717 2005-07-26 Stepan Kasal <kasal@ucw.cz>
10719 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

10724 * Makefile.maint: Update from Bison.
10726 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
10727 "<tab>" in comment, so that the point is understandable.
10729 2005-07-25 Stepan Kasal <kasal@ucw.cz>
10731 Rewrite substantial part of lib/autoconf/status.m4.
10732 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
10733 and CONFIG_COMMANDS are not processed in four separate loops.
10734 Instead, there is one main loop. This alows that the common code
10735 is expanded only once, thus config.status (and configure) is smaller.
10737 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
10738 the AC_LIST_FILES and cousins macros are no longer used.
10740 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
10741 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
10742 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
10743 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
10744 contain the initialization, nor the for loop, nor the associated
10745 commands; all these go to ...
10746 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
10747 _AC_OUTPUT_CONFIG_STATUS.
10748 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
10749 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
10750 (_AC_OUTPUT_FILE): The creation of the sed script ...
10751 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
10752 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
10753 _AC_OUTPUT_MAIN_LOOP.
10754 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
10755 _AC_CONFIG_COMMANDS): Use ...
10756 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
10757 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
10758 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
10759 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
10760 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
10761 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
10763 (_AC_CONFIG_UNIQUE): Update.
10764 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
10765 Replaced by this ...
10766 (_AC_LIST_TAGS): ... new common macro.
10767 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
10768 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
10769 (_AC_LIST_TAG_COMMANDS): ... new common macro.
10770 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
10771 this didn't belong to the `config commands' section.
10772 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
10773 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
10774 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
10775 to the `config commands' section either.
10776 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
10777 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
10779 ... and many changes to the comments nearby.
10781 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
10782 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
10783 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
10784 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
10785 (#define header templates): The comment at the top of the generated
10786 header now includes the name(s) of the source file(s).
10788 Several unrelated small changes:
10790 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
10791 parameter to AC_DIAGNOSE.
10792 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
10793 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
10794 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
10795 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
10796 with AU::AC_OUTPUT.
10797 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
10798 in AC_OUTPUT doesn't double-quote it either.
10799 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
10802 2005-07-10 Stepan Kasal <kasal@ucw.cz>
10804 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
10805 versions of Portland Group compiler produce single- and double-quoted
10806 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
10807 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
10809 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
10811 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
10812 This is a corrected version of yesterday's patch.
10814 2005-07-07 Stepan Kasal <kasal@ucw.cz>
10816 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
10817 path, too; insert a "===" to emphasize the line.
10819 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
10820 ac_cv_build_alias to ac_build_alias.
10821 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
10823 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
10824 change eliminates it. Problem reported by Alexandre Duret-Lutz.
10825 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
10826 (AC_ARG_VAR): ... here.
10827 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
10830 Keep a list of all precious variables and process them with one simple
10831 for loop, instead of expanding all commands, or, OTOH, complicated
10832 processing of output of "set".
10833 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
10834 variable names in new macro...
10835 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
10836 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
10837 a loop to assign all ac_env_* and ac_cv_env_* variables.
10838 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
10840 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
10841 its value to shell variable ac_precious_vars and call
10842 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
10843 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
10844 _AC_ARG_VAR_VALIDATE.
10846 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
10847 and the AC_SUBSTs ...

10851 the ac_subst_files section in config.log.

10859 * lib/autoconf/c.m4 (AC_C_TYPEOF): New macro.
10860 * tests/c.at (C keywords): Test AC_C_TYPEOF.
10862 Fix problems reported by Nicolas Joly.

10865 They are generated by the Tru64 v5.1B shell.
10867 2005-07-05 Stepan Kasal <kasal@ucw.cz>
10869 Fix my changes from 2005-07-01; reported by Noah Misch.
10870 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
10871 description, the macro now accepts only a single tag.
10872 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
10874 Fix cases when the varsions of Autoconf and Autotest don't match.
10875 Reported by Noah Misch.
10876 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
10877 at_top_builddir, for compatibility with older autotest.
10878 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
10879 is not set, use at_top_builddir, for compatibility with older
10880 versions of autoconf.
10882 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
10884 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
10885 Problem reported by Patrick Welche.
10887 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
10889 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
10890 sed substitution command, so that we allow | in program prefixes
10891 and program suffixes. (& is a problem anyway; we're not fixing
10893 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
10894 configure_input, top_builddir, srcdir, etc.
10895 * lib/autotest/general.m4 (AT_INIT): Likewise, for
10896 PATH_SEPARATOR in AUTOTEST_PATH.
10898 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
10900 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
10901 for loop over config.site files using `set', to allow
10902 directory names containing IFS characters.
10904 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
10906 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
10907 directories with weird names. Apparently some people like living
10908 on the edge. However, improve the test that "pwd" actually does
10909 report a name for the working directory.
10910 * NEWS: Remove the claim that we test for funny chars in dir names.
10912 2005-07-01 Stepan Kasal <kasal@ucw.cz>
10914 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
10916 * lib/m4sugar/m4sugar.m4 (m4_foreach_w): ... by this new macro.
10917 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES, _AC_CONFIG_UNIQUE):

10924 about #include <config.h>.
10925 (Generic Functions): Mention the Gnulib project.
10926 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
10928 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
10929 document to output the default config_* lists to config.status.
10930 Don't recognize option --file, if the functionality is not there.
10931 Likewise for --header; moreover, recognize --he and --h as shortcuts
10932 for --help in that case.
10934 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
10935 matches the order of execution. No code changed.
10937 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10939 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
10940 single-quoted -cmdline argument in Portland Group compiler.

10947 2005-06-29 Stepan Kasal <kasal@ucw.cz>
10949 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
10950 descriptors to child processes; reported by Norman Gray.
10952 2005-06-29 Stepan Kasal <kasal@ucw.cz>
10954 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
10956 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
10957 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
10958 (AC_SUBST): Call it.
10959 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
10960 the directory specific variables; but don't call it for configure_input.
10962 2005-06-28 Derek Price <derek@ximbiot.com>
10964 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
10967 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
10969 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
10970 directory have inherent problems with special characters like spaces,
10971 due to limitations in Make syntax. Problem reported by Alexandre
10973 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
10974 Also, fix Tru64 porting problem with shell patterns,
10975 reported by Ralf Wildenhues.

10985 Fix some more shell quoting problems. Prompted by a bug report
10986 from Justace Clutter.
10987 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
10988 variable into diagnostic. Make the diagnostic an error, not a warning,
10989 because we really don't support spaces and suchlike in dir names.
10990 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
10991 Don't worry about backslashes in srcdir; it can't happen now.
10992 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
10993 Simplify ac_optarg handling.
10994 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

11002 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
11004 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
11005 that '\|' is not allowed in BREs; recommend using newline separated
11006 list of patterns instead of multiple -e options.
11008 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
11010 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

11014 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
11016 2005-06-21 Stepan Kasal <kasal@ucw.cz>
11018 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
11019 b, t, r, w commands require single space, while : cannot have any.
11020 (Special Shell Variables): Fix sed code this in the example.
11021 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
11022 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
11024 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
11025 expand to the empty list. Don't use two pairs of m4_changequote,
11026 it's not necessary.
11028 2005-06-20 Derek Price <derek@ximbiot.com>
11030 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
11032 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
11034 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
11035 * doc/autoconf.texi:
11036 Don't mention Solaris versions so much, if a
11037 problem is common to all extant versions of Solaris. Say "SunOS
11038 4" instead of "SunOS" for SunOS 4.
11039 (awk): Mention more of the limitations of traditional Awk.
11040 (cat): Don't talk about cat -v.
11042 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
11044 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
11045 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
11046 but the implementation is entirely different and is designed
11047 to be compatible with glibc strverscmp.
11048 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
11050 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
11051 on Mac OS X 10.4 reported by Peter O'Gorman in:
11052 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
11053 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
11054 Use shell builtins rather than 'expr', to work around expr bug.
11056 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
11058 * doc/autoconf.texi: "filesystem" -> "file system".
11059 "behaviour" -> "behavior".
11060 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
11061 * lib/autoconf/general.m4: Omit blank after ":" sed command,
11063 * lib/m4sugar/m4sh.m4: Likewise.
11064 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
11065 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
11067 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
11068 (.x.1): Ignore the time stamp in the .TH line when deciding whether
11069 to update the man page. That way, we don't have to check in new
11070 man pages every month.
11072 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
11073 quotes and backslashes. Patch from Derek Price.

11082 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
11083 -u, since it outputs chatter if the input files are the same.
11084 Problem reported by Ralf Menzel.
11086 2005-06-08 Derek Price <derek@ximbiot.com>
11088 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
11089 renaming them since they are about to be redefined anyhow.
11091 2005-06-08 Derek Price <derek@ximbiot.com>
11093 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
11094 redefined M4 macros to this node. Document m4_include & m4_sinclude.
11095 Move m4_undefine to alphabetical order.
11097 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
11099 * README: Recommend GNU M4 1.4.3 or later.
11100 * doc/autoconf.texi (Introduction): Likewise.
11101 Reword to avoid some formatting glitches.
11102 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
11103 Clarify explanation of HP compiler bug.
11104 Redo example output tp match current CVS snapshot.
11105 Use @example.org in email addresses when the examples
11106 might get inadvertently cut-and-pasted into user code.
11107 Remove example of autom4te usage that doesn't seem to work now.
11108 Use modern AC_INIT (except when the example is meant to be
11109 shown with Autoconf 2.13).
11110 Update ksh info for Solaris 9 and later.
11112 Modernize description of Automake versions a bit.
11113 Don't claim a future version of Autoconf is near.
11114 * doc/install.texi: Reword to avoid some formatting glitches.
11116 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11118 * doc/autoconf.texi: Add [] to examples, so that the manual
11119 follows its own advice about quoting better.
11120 Reword to avoid some formatting glitches.
11121 * doc/installt.exi: Reword to avoid some formatting glitches.
11123 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
11124 Tru64 ksh pattern matching bug. Reported against Libtool by
11125 Albert Chin <libtool@mlists.thewrittenword.com> and
11126 Nicolas Joly <njoly@pasteur.fr>.
11128 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11130 m4_cdr of one-member list was [[]] (one-member list containing an
11131 empty string) instead of [] (an empty list. Callers were skewed to
11132 match this misbehaviour. As a consequence of this:
11133 - m4_foreach([x], [], [foo]) expanded to `foo', while
11134 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
11135 This bug has been fixed:
11137 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
11138 expand to an empty string; print error msg if called without
11140 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
11141 misbehaviour; handle [] and [[]] correctly.
11143 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11145 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
11146 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
11147 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
11149 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
11151 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
11152 swallow records with more than 99 fields.
11153 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
11154 parse the long line.
11156 2005-06-04 Stepan Kasal <kasal@ucw.cz>
11158 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
11159 swallow literals longer than 399. Reported by Ralf Wildenhues.
11160 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
11161 to workaround this limitation.
11163 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
11165 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
11166 to gfortran, and make these the first two compiler names
11167 checked (following the general autoconf preference for gcc).
11169 2005-06-03 Stepan Kasal <kasal@ucw.cz>
11171 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
11172 (DISTCLEANFILES): Remove $(check_SCRIPTS).
11173 (testsuite): Make sure autotest.m4f is up-to-date before using it.
11175 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
11177 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
11178 expression of unbounded size when processing the --list
11179 option. This runs afoul of a limit of 399 bytes per regular
11180 expression on AIX. Problem reported by Ralf Wildenhues.
11182 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
11184 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
11185 * doc/autoconf.texi (Particular Headers): Reword example
11186 for multiline stdbool replacement.
11187 (Setting Output Variables): Reword text a bit. Don't
11188 give all the details about |#_!!_#|.
11189 Reword description of line replacement.
11191 2005-05-31 Dan Manthey <dan_manthey@partech.com>
11193 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
11194 now contain newlines, and substituted files must be referenced on
11195 a line alone; the sed scripts to substitute them are now very
11197 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
11198 commands can be put in a sed script portably.
11199 * doc/autoconf.texi (Setting Output Variables): Document above
11200 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
11201 use of multiline substitution.
11202 * tests/torture.at: No longer expect substitution of newline to fail.

11211 * tests/local.at: Don't attempt to check for negated character
11212 classes in shell scripts. The test was too brittle.
11214 2005-05-25 Stepan Kasal <kasal@ucw.cz>
11216 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
11217 * doc/autoconf.texi (Limitations of Builtins): Document this
11220 2005-05-24 Stepan Kasal <kasal@ucw.cz>
11222 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
11223 common code; used in many places in the tree.
11224 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
11225 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
11227 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
11229 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
11230 messages when ac_unique_file is not found.
11231 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
11232 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
11233 commands, for consistency with AC_MSG_ERROR and such.
11235 * bin/autoconf.as: Make more use of "shift 2" in option processing.
11237 * bin/Makefile.am: Merge the two rules for creating scripts.
11239 2005-05-23 Stepan Kasal <kasal@ucw.cz>
11241 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
11242 obsolete; it was never documented.
11243 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
11245 2005-05-20 Stepan Kasal <kasal@ucw.cz>
11247 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
11248 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
11249 (ac_top_builddir): ... this ...
11250 (ac_top_build_prefix): ... to this; the old name is also kept, for
11251 backward compatibility.
11252 (ac_top_builddir_sub): New variable, without the trailing slash,
11254 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
11255 * doc/autoconf.texi (Configuration Actions): Rename
11256 ac_top_builddir to ac_top_build_prefix.
11257 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
11258 at_top_builddir to at_top_build_prefix.

11266 2005-05-17 Stepan Kasal <kasal@ucw.cz>
11268 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
11269 argument to m4_foreach. I guess it was necessary in the past,
11270 but I think it's a no-op now.
11272 2005-05-17 Stepan Kasal <kasal@ucw.cz>
11274 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
11275 ``cat <<_ACEOF'' commands to one.
11276 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
11277 * lib/autoconf/status.m4: On various places, use expr instead of
11279 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
11280 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
11281 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
11283 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
11284 the wrong patterns between ``case'' and ``esac.'' The previous
11285 code had false positives.
11287 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
11289 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

11354 quoting rules. Problems noted by Stepan Kasal.
11355 Also, throughout this document, be more careful about white space.
11356 "blank", "white space", and "space" all have different meanings
11357 and we should be careful to say what we mean.
11359 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
11361 Fix C++ related problems reported by Werner Lemberg.

11396 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
11397 by AC_DEFINE; it was a mistake.

11400 2005-04-25 Stepan Kasal <kasal@ucw.cz>
11402 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
11404 2005-04-22 Stepan Kasal <kasal@ucw.cz>
11406 * doc/autoconf.texi (External Software): Quadrigraphs are not
11407 processed correctly in AS_HELP_STRING; avoid this in the examples.
11408 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
11409 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
11410 comment and reduce m4_default([foo], []) to [foo].
11411 (m4_strip): Update the explanation.
11413 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
11415 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
11416 Remove core.conftest.* too; it's generated by Tru64 5.1.
11417 Problem reported by Jennis Pruett.
11418 * lib/autoconf/functions.m4
11419 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
11420 Don't bother to remove core files; AC_RUN_IFELSE should do that

11425 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

11494 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
11496 * doc/autoconf.texi: Fix some systematic formatting problems.
11497 ".)" needs a following @: if not at the end of a sentence, and
11498 similarly for "!)". "etc." should be preceded by a comma.
11499 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.

11515 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
11516 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
11517 from a Common Lisp's `cl'.
11518 (AC_PROG_CXX): Behave according to the documentation: don't
11519 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
11520 make the variable CCC precious; use `cl.exe', not `cl'.

11525 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
11526 /dev/null, as "configure" shouldn't read stdin, and this insulates
11527 us from problems (e.g., when testing for "cl"). Also, do this
11528 redirection before invoking "hostname" or "uname", and keep the
11529 original input stream available via...

11549 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.

11555 Undo previous change, except keep the change to
11556 lib/autoconf/programs.m4 that replaced grep with shell

11566 before invoking "hostname" or "uname".

11741 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
11742 Update the long comment explaining it.
11744 m4_require no longer writes an ``is required by'' line to the
11745 execution stack. It contains only one bit of non-redundant
11746 information: that the macro was required, not called. And even
11747 this bit is useless in most situations: have you ever met a macro
11748 which both calls and requires the same macro?
11750 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
11751 (_m4_defun_pro_outer): ... only via this macro, for the outermost

11799 Warn about newline stripping in `` and $(). Update Solaris

11855 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
11856 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
11857 stored in _m4_divert_diversion or _m4_divert_dump.
11858 (m4_divert_pop): When the parameter is given, compare the symbolic
11859 name with the last diversion pushed on the stack. Previously, the
11860 current diversion was compared with the numeric value of the
11861 diversion given as the parameter.
11862 (m4_require): If the macro hasn't been expanded yet, call ...

12170 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
12171 "char c = '\200';" rather than "char c = 0x80;" as the

12350 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
12352 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
12353 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
12354 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
12355 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
12357 More fixes to support spaces in the name of the build directory.
12358 This isn't a complete fix but it's an improvement.
12360 * bin/autoconf.as (autom4te_options): New var.
12361 Use it instead of appending to AUTOM4TE, so that we can allow
12362 spaces in the build directory's absolute name.
12363 * bin/autoheader.in ($autoconf): Allow spaces in file names.
12364 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
12365 AT_CHECK_NOESCAPE): Likewise.
12366 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
12367 main program): Likewise.
12369 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
12371 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

12377 * doc/autoconf.texi (Function Portability): Document isinf and
12378 and isnan. From a suggestion by Kevin Ryde.
12380 * lib/Autom4te/General.pm (END): Return correct exit status even
12381 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
12383 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
12385 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
12386 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
12387 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
12389 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
12391 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
12392 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
12393 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
12394 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
12395 * lib/autom4te.in (Automake-preselections): Preselect
12396 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
12398 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
12400 * lib/autom4te.in (Automake-preselections): Preselect
12401 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
12404 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
12406 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
12408 * doc/autoconf.texi (Shellology): Mention BIN_SH.
12409 Document problem with "`""`" in pdksh POSIX mode.
12411 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
12413 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
12414 with pdksh, too. Problem reported by Patrick Welche via
12416 * doc/autoconf.texi (Shellology): Note that set -o posix is
12417 useful for pkdsh, too.
12419 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
12421 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
12422 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
12423 Don't fail if ENV or BASH_ENV is readonly.
12424 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
12425 etc. are read only. Problem reported by Ludovic Courtes.
12427 2004-06-23 Noah Misch <noah@cs.caltech.edu>
12429 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
12430 zsh, disable GLOB_SUBST to avoid backslash handling problems.
12433 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
12435 * doc/autoconf.texi (File System Conventions): Warn about
12436 names like "aux". Problem reported by Eric Blake.
12438 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
12439 by zero instead of array size, so that we can use any arithmetic
12440 constant expression (instead of requiring an integer constant
12441 expression). This allows us to test expressions like DBL_MAX <
12442 LDBL_MAX, which didn't conform to the C standard using the old
12444 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
12445 now that we can do floating-point tests at compile time.
12447 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
12449 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
12450 and LDBL_EPSILON, as the resulting expression isn't an
12451 integer constant expression and violates the C standard.
12452 Problem reported by Nelson H. F. Beebe. Also, check
12453 for "L" suffix, and check that long double doesn't have
12454 worse range or precision than double, that mixed-mode
12455 arithmetic doesn't generate a diagnostic, that double
12456 constants fit in long double.
12458 2004-06-03 Kevin Ryde <user42@zip.com.au>
12460 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
12461 malloc(0) and realloc(NULL,size).
12463 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
12466 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
12468 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
12469 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
12472 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
12474 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
12475 can be rewritten using if-then-else. Suggested by Bruno Haible.
12477 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
12479 * doc/autoconf.texi (testsuite Scripts): Fix typo.
12480 Problem reported by Stepan Kasal.
12482 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
12484 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
12485 change). Patch reported by Ralf Wildenhues in
12486 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
12488 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
12489 function F exists if the compiler and linker let you compile an
12490 expression like (F != 0). Recent versions of GCC optimize away
12491 the reference to F in that case, since every function address must
12492 be nonzero, so the link succeeds even if F does not exist.
12493 Problem reported by Manu in
12494 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
12496 * doc/autoconf.texi (Systemology): Standardize on the spelling of
12497 "Unix". Many uses changed.
12498 (Limitations of Builtins): Explain better why the ! command isn't
12501 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
12503 * lib/autom4te.in (Automake-preselections): Preselect
12504 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
12506 2004-05-19 Kevin Ryde <user42@zip.com.au>
12508 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
12509 referencing AC_FUNC_STRERROR_R.
12511 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
12512 note pessimistic assumption when cross compiling.
12514 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
12516 * doc/autoconf.texi (Limitations of Make): Note that BSD make
12517 (until 2004) invoked subcommands with sh -e, contra POSIX.
12518 Reported by Kevin Ryde.
12520 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
12522 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
12523 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
12524 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
12525 `test -f " /usr/bin/grep"', which _always_ failed.
12526 (AC_PROG_SED): Ditto bogus PATH fix.
12527 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
12528 requires that grep correctly supports _multiple_ `-e' options, rather
12529 than stating only that grep should accept `-e'.
12531 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
12533 Port to C99, which requires that 'exit' be declared.
12535 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
12536 to ensure that stdlib.h is included.
12537 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
12538 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
12539 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
12540 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
12541 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
12542 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
12543 when using 'exit' in a test; C99 requires that 'exit' be declared.
12545 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
12547 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
12548 now prefers 'grep' implementations that accept -e.
12549 (Limitations of Usual Tools): Describe problems of traditional
12550 egrep and fgrep with long input lines, and of traditional grep
12552 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
12553 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
12554 All callers changed. Append /usr/xpg4/bin to the PATH, for
12556 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
12557 the user with complaints about multiple -e options.
12558 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
12559 Define it with AC_PROG_GREP.
12560 * configure.ac (AC_PROG_GREP): Add.
12561 * lib/freeze.mk (GREP): New macro.
12563 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
12565 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
12566 a possible candidate only after all others fail, rather than
12567 consulting it first. This improves backward compatibility by
12568 better reflecting the way shell selection occurred in previous
12569 versions of Autoconf, and should help to avoid triggering latent
12570 problems in other packages, such as the one in Automake where zsh
12571 is not handled robustly:
12572 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
12573 Although it is not Autoconf's responsibility to work around
12574 problems in Automake, it nevertheless makes sense to avoid
12575 introducing unnecessary incompatibilites.
12577 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
12578 Gary V. Vaughan <gary@gnu.org>
12580 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
12581 how deeply nested we are when a suitable tool is found, set the
12582 ac_path_TOOL_found flag.
12583 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
12584 nested we are in this macro. Break out of all 3 nested loops if
12585 ac_path_TOOL_found is set.
12587 2004-04-21 Gary V. Vaughan <gary@gnu.org>
12589 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
12590 of the _AS_PATH_WALK loop too if GNU flavor is found.
12592 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
12594 * doc/autoconf.texi (Limitations of Make): Update documentation
12595 for `$<'. New entry `Long lines', based on a report from Simon
12596 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
12597 paragraph about DJGPP, based on a mail from Richard Dawe.
12599 2004-04-20 Paul Eggert <eggert@twinsun.com>
12601 * tests/c.at (C keywords): Don't assume that GCC supports
12602 "restrict" and "inline", as sufficiently-old GCC versions do not
12603 (also, GCC configured to be in pedantic C89 mode does not).
12604 Problem reported by Sumit Pandya in:
12605 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
12607 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
12608 consider -g to work if it generates warnings when plain compiles
12609 don't. Problem reported by Braden McDaniel in:
12610 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
12612 * doc/autoconf.texi (Slashes): New section, to document a problem
12613 reported by Jim Meyering in:
12614 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
12616 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
12617 linker output files before linking, to work around IRIX 6 linker bug.
12618 Problem reported by Rainer Orth in:
12619 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
12621 2004-04-20 Gary V. Vaughan <gary@gnu.org>
12623 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
12624 best tool so far counter rely on the tool path variable name to
12625 avoid checks for one tool being affected by the results of running
12626 the length check on a previous tool.
12628 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
12629 match expression argument, as different greps have different
12630 regular expression flavours.
12631 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
12633 (AC_PROG_EGREP): Pass 'EGREP$'.
12634 (AC_PROG_GREP): Pass 'GREP$'.
12636 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
12638 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
12639 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
12641 2004-03-29 Paul Eggert <eggert@twinsun.com>
12643 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
12644 Types, Specific Compiler Characteristics, System Services,
12645 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
12646 etc. consistently instead of 'long', 'short', 'unsigned' etc.
12647 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
12648 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

12659 2004-03-28 Paul Eggert <eggert@twinsun.com>
12661 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
12662 now defines HAVE_DECL_TZNAME if it is declared, when
12663 HAVE_STRUCT_TM_TM_ZONE is not defined.
12664 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
12665 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
12668 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
12670 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
12671 superfluous backslashing of quotes (") in sed expressions;
12672 thanks to Paul Eggert.
12674 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
12676 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
12677 Fortran compiler is ifort, also added pghpf; thanks to Nelson
12678 H. F. Beebe for the bug report.
12680 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
12682 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
12683 quoted -cmdline argument in Portland Group compiler (bug
12684 reported by Jeffrey J. Barteet).

12723 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
12724 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
12725 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a

12728 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.

12732 2004-03-03 Paul Eggert <eggert@twinsun.com>
12734 * bin/Makefile.am (edit): Don't use $< in a context where
12735 POSIX doesn't require support for it. Use $@.in instead.
12736 Problem reported by Anthony N. Frasso in
12737 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

12759 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
12760 (MAINTAINERCLEANFILES): Split into pieces,
12761 one per related section. Add $(srcdir)/wrapper.in.
12763 2004-02-09 Paul Eggert <eggert@twinsun.com>

12766 AC_SUBST provides no portable way to escape literal newlines.
12768 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
12769 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
12770 Darwin uses -lcrt2.o and there's little point to cataloging all
12771 the system variants. Partial fix reported by Andreas Waechter in:

12796 Eric Sunshine <sunshine@sunshineco.com>
12797 Paul Eggert <eggert@twinsun.com>
12799 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
12800 (AS_INIT): Output shell initialization there. Removed optional
12801 parameter. Expand _AS_SHELL_FN_SPY.
12802 (AS_INIT_WITH_SHELL_FN): Removed.
12803 (_AS_SHELL_FN_SPY): New macro.
12804 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
12806 (AS_SHELL_SANITIZE): Remove loop to find better shell
12807 and documentation for the parameter.
12808 (_AS_DETECT_BETTER_SHELL): Move it here.
12809 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
12810 (_AS_RUN): Move it here, support testing with eval.
12811 (AS_REQUIRE_SHELL_FN): Require shell functions when
12813 (_AS_LINENO_WORKS): Put around braces, we do not
12814 trigger the bash bug anymore.
12815 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
12816 use AS_INIT_WITH_SHELL_FN.
12817 * bin/autoconf.in, tests/wrapper.in: Regenerated.
12819 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

12824 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
12825 (AU_DEFUN): Honor the third parameter, create autoupdate
12826 macros with AU_DEFINE.
12827 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
12828 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
12829 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
12830 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
12831 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,
12832 AC_ARG_ARRAY, AC_CYGWIN, AC_EMXOS2, AC_MINGW32,

12834 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS,
12835 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
12836 * lib/autoconf/status.m4: Remove FIXME.

12847 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
12848 2003 (except 1997) to the list of copyright years. This undoes
12849 the 2003-05-22 change, which removed the older years from the list.
12850 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
12852 2004-01-27 Gary V. Vaughan <gary@gnu.org>
12853 Albert Chin-A-Young <china@thewrittenword.com>
12855 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
12856 grep or ggrep program in PATH that accepts as long lines as
12858 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
12860 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
12861 egrep and fgrep respectively if $GREP -E/-F don't work.
12862 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
12863 _AC_PROG_GREP, and AC_PROG_SED.
12864 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
12865 longest input length accepted by a command.
12866 (AC_PROG_SED): Use it.
12867 * doc/autoconf.texi (Particular Programs): Document the changes.
12870 2004-01-27 Paul Eggert <eggert@twinsun.com>
12872 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
12873 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
12874 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
12875 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
12877 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
12878 bin/autoconf.in, config/Makefile.in, config/config.guess,
12879 config/config.sub, config/install-sh, config/mdate-sh,
12880 config/mkinstalldirs, config/texinfo.tex, doc/Makefile.in,
12881 lib/Makefile.in, lib/Autom4te/Makefile.in,
12882 lib/autoconf/Makefile.in, lib/autoscan/Makefile.in,

12890 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
12891 tests/actypes.at: Regenerate and/or sync with original
12894 2004-01-26 Paul Eggert <eggert@twinsun.com>
12896 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
12897 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
12898 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
12899 not <inttypes.h>. Problem reported by Tim Mooney in
12900 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
12901 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
12904 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
12905 otherwise "make check" fails because it forbids cmp (I guess
12906 because cmp treats files as binary on DOS-like systems).
12908 * tests/mktests.sh: Update copyright date to 2004, since some tests
12909 have changed in 2004.
12911 2004-01-23 Gary V. Vaughan <gary@gnu.org>
12913 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
12914 non-truncating sed or gsed program in PATH.
12915 * tests/acprograms.at: Add it.
12916 * doc/autoconf.texi (Particular Programs): Document it.
12919 2004-01-15 Paul Eggert <eggert@twinsun.com>
12921 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
12922 -std1 disables some useful extensions on Tru64. Problem reported
12923 by N. Lichtmaier in
12924 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
12926 2004-01-14 Paul Eggert <eggert@twinsun.com>
12928 * doc/autoconf.texi (Programming in M4sh): Document that
12929 AS_MKDIR_P succeeds if the destination is a symbolic link
12930 to an existing directory.
12931 (Limitations of Usual Tools): Note that mkdir -p might not
12932 succeed on symlinks to directories.
12934 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
12936 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
12937 * bin/autoheader.in: Grammar fix in message.
12938 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
12939 Test for dir before calling mkdir -p. (trivial changes)
12941 2004-01-13 Eric Blake <ebb9@byu.net>
12943 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
12944 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
12946 2004-01-10 Jim Meyering <jim@meyering.net>
12948 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
12950 2004-01-09 Paul Eggert <eggert@twinsun.com>
12952 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
12953 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
12954 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
12955 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
12956 AC_COMPILE_IFELSE, since we now assume our caller invokes
12957 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
12958 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
12959 of AC_RUN_IFELSE; this avoids the warning mentioned above.
12960 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
12962 2004-01-07 Paul Eggert <eggert@twinsun.com>
12964 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
12965 `"'...'"`, as it's confusing (and I suspect it may not work on
12966 some platforms). The code was incorrect anyway, as it assumed
12967 that \$ evaluated to itself in that context. Reported by
12968 Alexandre Duret-Lutz.
12970 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
12972 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
12973 and _LT_AC_TAGCONFIG.
12975 2004-01-06 Paul Eggert <eggert@twinsun.com>
12977 * doc/autoconf.texi (One Macro Call): Fix an incorrect
12978 example, and add more examples. Reported by Eric Sunshine.
12980 2004-01-05 Paul Eggert <eggert@twinsun.com>
12982 * doc/autoconf.texi (Limitations of Usual Tools):
12983 Remove warning against "rm -fr" introduced yesterday; it
12986 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
12987 autoscan, autoupdate, ifnames): Don't use chmod -w.
12988 * lib/Makefile.am (autom4te.cfg): Likewise.
12989 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
12992 2004-01-04 Paul Eggert <eggert@twinsun.com>
12993 Paolo Bonzini <bonzini@gnu.org>
12995 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
12996 by doing lineno substitution only on lines containing "$LINENO".
12998 2004-01-04 Paul Eggert <eggert@twinsun.com>
13000 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
13001 Use "rm -f" to remove conftest.sed, not plain "rm".
13002 Bug reported by David Relson in
13003 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
13005 * Makefile.am (autom4te-update):
13006 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
13007 * Makefile.maint (my-distcheck, do-po-update): Likewise.
13008 * doc/autoconf.texi (Guidelines): Likewise.
13009 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

13013 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
13014 * tests/Makefile.am (clean-local): Likewise.
13015 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
13017 * doc/autoconf.texi (Limitations of Usual Tools):
13018 Warn against "rm -fr".
13020 2004-01-03 Paul Eggert <eggert@twinsun.com>
13022 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
13023 -c -o might not work. From a suggestion by Kevin Ryde.
13024 (C Compiler, Generating Sources, Limitations
13025 of Usual Tools, Limitations of Make, Making testsuite Scripts):
13026 Don't put '-o' after non-options, as POSIX doesn't allow this.
13027 Mention that cc's name might be gcc or c89 or whatever.
13029 2004-01-04 Kevin Ryde <user42@zip.com.au>
13031 * doc/autoconf.texi: Add various further index entries.
13033 2003-12-29 Paul Eggert <eggert@twinsun.com>
13035 * bin/autoreconf.in (autoreconf_current_directory):
13036 Fix typo: mkdir without umask arg.
13038 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
13040 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
13041 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
13042 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
13043 explanation clearer.
13045 2003-12-24 Andreas Schwab <schwab@suse.de>
13047 * doc/autoconf.texi (Default Includes): Fix misspelling of
13048 AC_INCLUDES_DEFAULT.

13053 * configure: Regenerate.
13054 * tests/atlocal.in: Store the result here.
13055 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
13056 tools.at, looking in atlocal's ac_cv_sh_n_works instead
13057 of explicitly testing.
13058 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
13059 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
13060 * tests/tools.at (Syntax of the shell scripts): Simplify
13061 using AT_CHECK_SHELL_SYNTAX.

13063 AT_CHECK_PERL_SYNTAX.

13067 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
13068 stderr to /dev/null.

13075 Extracted from AS_SHELL_SANITIZE.
13076 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
13078 (AS_SHELL_SANITIZE): Move reinvocation code from
13079 _AS_LINENO_WORKS, use it to find out if shell
13081 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
13083 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
13084 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

13130 parameter of AU_DEFUN.
13131 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.

13133 Use AC_DEFUN directly, not AU_DEFINE.
13134 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
13135 the expanded body, consistently with other macros such as AC_USG.
13137 2003-11-17 Paul Eggert <eggert@twinsun.com>
13139 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
13140 into the initial confdefs.h, to work around a bug in NextStep 3.3
13141 patch 3 reported by Eric Sunshine.
13143 2003-11-15 Kevin Ryde <user42@zip.com.au>
13145 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
13146 than $target since the latter is not usual, add guidelines on when to
13147 use or not use the system type.
13149 2003-11-12 Derek Price <derek@ximbiot.com>
13151 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
13152 typo misrepaired by an auto-spellcheck.
13154 2003-11-12 Akim Demaille <akim@epita.fr>
13156 * bin/autoreconf.in (&parse_args): Don't call automake with
13157 --force-missing unless it actually supports it.

13171 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE
13172 so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,
13173 and ac_abs_top_srcdir are absolute paths.
13174 * lib/m4sugar/m4sh.m4 (AS_SET_CATFILE): Remove misleading comment.

13180 2003-11-05 Kevin Ryde <user42@zip.com.au>

13199 computing the absolute path to d1 in the source hierarchy: it may
13200 not exist at all. So don't cd into it.
13201 From Alexandre Duret-Lutz.
13202 http://mail.gnu.org/archive/html/bug-autoconf/2003-10/msg00205.html

13207 * lib/autoconf/status.m4 (_AC_SRCPATHS): Use it.
13209 2003-11-03 Pavel Roskin <proski@gnu.org>
13211 * doc/autoconf.texi (Generic Structure Checks): Describe

13224 * bin/autom4te.in (&freeze): Use a less likely warning separator
13225 than `\n\n', so that `\n\n\n' is valid in warnings.

13324 Problems reported by Eric Sunshine.
13326 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
13328 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
13329 -mGLOB_options_string stuff for Intel ifc, which can cause

13353 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
13354 cache variable instead of $G77 to decide whether to include -O2,
13355 since $G77 is specific to Fortran 77.

13359 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
13360 free" flag. Re-order flags tested into rough order of popularity.
13362 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
13364 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
13365 arguments so that it can be used with syntax identical to
13366 AC_PROG_F77, and so that we can more easily decide to
13367 remove/deprecate the DIALECT optional argument in the future if it
13368 proves troublesome.
13369 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
13370 non-freeform-supporting compilers. Document freeform flags.
13372 2003-10-03 Akim Demaille <akim@epita.fr>

13434 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
13435 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
13436 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
13437 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
13439 2003-09-26 Akim Demaille <akim@epita.fr>
13441 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
13442 directory for AC_CONFIG_COMMANDS' first argument exists.
13443 This makes valid the invocation of _AC_SRCPATH that follows.
13444 Reported by Eric Sunshine.

13468 The test suite are sometimes assigning timings incorrectly.
13469 Reported by Henk Krus.
13470 Diagnosed by Nicolas Joly.
13472 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
13474 Instead of making AT_help a sequence of assignments to grow
13475 $at_help_all, just make AT_help_all be the growing contents of
13476 $at_help_all, and make a single assignment in...
13478 (at_times_skip): Flip the meaning and rename as...
13479 (at_times_p): this.
13480 (AT_INIT): When summarizing the test that ran, remove

13490 (ifnames): chmod -w.
13491 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
13492 executables, not bin/ executables! Otherwise all the magic needed
13493 to find non installed files is turned off. This caused a failure
13494 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
13495 as found in its environment (sent by tests/autoreconf): pointing
13496 to bin/autom4te that could not find its files.
13497 * tests/mktests.sh: Force the replacement of generated files, for
13498 the sake of "mv" program that are interactive when overwriting a

13507 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
13508 Paul Eggert <eggert@twinsun.com>
13510 Trivial change to support GCC's configuration procedure.

13546 willing to edit the output files.
13548 2003-09-10 Akim Demaille <akim@epita.fr>
13550 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
13551 and AC_FC_FREEFORM.
13552 * tests/mktests.sh: Skip AC_FC_SRCEXT.
13553 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

13593 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
13595 Add support for newer Fortran dialects. The F77 interface is
13596 unchanged, and continues to support Fortran 77. New FC macros
13597 correspond to all the old F77 macros, with output variables FC,
13598 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
13599 available dialect, but older dialects can be specified. There are
13600 new macros AC_FC_SRCEXT to set the source extension, and
13601 AC_FC_FREEFORM to accept free-form source files.
13603 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

13639 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
13640 are defaulted by AT_CHECK anyway.
13641 Use AT_CHECK_AUTOM4TE.

13711 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
13712 (&verbose): Remove.
13713 (&getopt): Adjust the note and verb channels, depending upon
13715 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
13716 * bin/autoupdate.in: Adjust.
13717 Use &verb, not &verbose.
13719 2003-08-21 Akim Demaille <akim@epita.fr>
13721 * bin/autoheader.in (&parse_args): Use &parse_warnings and
13723 ($help): Use Autom4te::ChannelDefs::usage.
13724 * bin/autoscan.in: Use Autom4te::ChannelDefs.
13725 * lib/Autom4te/General.pm: Don't export error: you don't own it.
13727 2003-08-21 Akim Demaille <akim@epita.fr>
13729 First stab at preserving warnings between calls to autom4te,
13730 including when the cache is used.
13732 There are still several issues: (i) there are too many runs of m4
13733 (one for include, one for warnings, and some more), (ii) warnings
13734 spreading on several lines are not handled gracefully, (iii) the
13735 code meant to have the call stack display for errors does not work
13736 (its handling should move from m4 to autom4te).
13738 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
13740 (@preselect): Add m4_warn.
13741 ($exit_status): Remove, use $exit_code.
13742 ($help): Use Autom4te::ChannelDefs::usage.
13743 (&handle_m4): No longer define the m4_warnings.
13744 At each run, extract and report the warnings.
13745 Always cache the result, including if the exit status is on
13746 failure, since if nothing changes, we should result in the same
13747 failure, hence we can use the cache.
13748 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
13749 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
13751 (m4_warn): Redefine as a do-nothing: it is its invocation that
13752 matters, as warnings are now reported via traces.
13753 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
13754 the contents of m4_warn: make it _call_ m4_warn, so that tracing
13755 the latter reveals calls to the former.
13759 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
13761 2003-08-21 Akim Demaille <akim@epita.fr>
13763 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

13768 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
13770 * lib/Autom4te/ChannelDefs.pm: Doc typos.
13771 (&parse_warnings): Accept a list of warning requests.
13772 (&usage): Return a string, not a side effect.
13773 (cross): New warning category.
13775 2003-08-21 Akim Demaille <akim@epita.fr>
13777 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
13778 (&require_configure_ac): Accept an optional directory argument.
13779 ($configure_ac): Remove.
13780 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
13781 (&catfile): Remove.
13782 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
13783 * bin/autoscan.in: Adjust.
13785 2003-08-20 Akim Demaille <akim@epita.fr>

13788 Reported by Alexandre Duret-Lutz.
13790 2003-08-20 Akim Demaille <akim@epita.fr>
13792 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
13793 * bin/autom4te: Adjust.
13794 In particular, be Autoconf tools are really silent when properly
13795 working, bind the verbosity of the 'note' channel to $verbose.
13796 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
13797 (&xsystem, &contents): Remove, since they are exported by...
13798 * lib/Autom4te/FileUtils.pm: this.
13800 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
13801 * lib/Autom4te/FileUtils.pm: here.
13803 2003-08-20 Akim Demaille <akim@epita.fr>
13805 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
13806 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

13862 2003-08-13 Derek Price <derek@ximbiot.com>
13864 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
13867 2003-08-12 Derek Price <derek@ximbiot.com>
13869 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.

13871 (_AT_CHECK): ...this new macro.
13873 2003-08-07 Derek Price <derek@ximbiot.com>

13887 -lcrt1.o, for OS X. (trivial change)
13889 2003-07-07 Paul Eggert <eggert@twinsun.com>
13891 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
13892 inside '#ifndef __cplusplus'. Problem reported by
13895 2003-07-06 Bill Clarke <llib@computer.org>
13897 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
13898 'long', not 'int', for benefit of Sun's recent C++ compilers
13899 (trivial change). See:

13916 From Gareth McCaughan.
13918 2003-06-23 Akim Demaille <akim@epita.fr>
13920 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
13921 not all of them. This fixes 1. the fact that when testing
13922 Autoconf there are many many config.log, 2. the incorrect use of
13923 top_srcdir to find config.log.
13924 Don't mix the detailed output of failed test with the summary of
13925 failures. Rather, append detailed log afterwards.
13927 2003-06-23 Akim Demaille <akim@epita.fr>
13929 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
13930 always run: output config.log on $at_group_log.
13932 2003-06-23 Akim Demaille <akim@epita.fr>
13934 * tests/torture.at (#define header templates): Don't use quotes in

13987 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
13988 (AT_INIT): Support for expected failures.

14007 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
14008 (handle_exec_errors): New function. Work around $! being
14009 altered by WEXITSTATUS.
14010 (xqx, xsystem): Use handle_exec_errors.
14012 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
14014 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
14015 Do not call `_exit()', simply modify `$?'.
14016 (xsystem): Reset $! before running system, and check it afterward.
14017 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
14018 63 for version mismatches.
14020 2003-05-23 Akim Demaille <akim@epita.fr>
14022 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
14023 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
14024 the middle of a line).
14025 * lib/m4sugar/m4sugar.m4: Likewise.
14026 Remove useless spaces in comments.
14028 2003-05-23 Akim Demaille <akim@epita.fr>
14030 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
14031 exit 63, so that we (or Automake's "missing") can tell the
14032 difference with a plain failure.
14033 * doc/autoconf.texi (Notices): Adjust.

14042 Paul Eggert <eggert@twinsun.com>
14044 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
14045 Remove `#include <stdlib.h>' from the list; we should never
14046 make confdefs.h include <stdlib.h> or <cstdlib>, because the
14047 resulting namespace pollution would cause other tests to fail.
14048 Configure scripts run with some older versions of g++ and HP's
14049 aCC would fail due to such an #include. Problems reported by
14050 Matthew Mueller in <http://bugs.debian.org/120704> and by
14052 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
14053 In the test, use the test declaration before including <stdlib.h>,
14054 as that's closer to how it'll be used.
14056 2003-05-23 Akim Demaille <akim@epita.fr>
14058 * doc/autoconf.texi (Header Portability): ucred.h.
14061 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
14063 Overhaul Autotest's logging: generate separate log files
14064 in testsuite.dir/NNN/testsuite.log, and append them to
14065 testsuite.log instead of re-running the test verbosely.
14067 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
14068 file descriptor, write 0 to at_status_file instead of setting
14069 at_status=0, initialize some new variables (at_status_file,
14070 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
14071 to rerun the tests, instead append the at_group_log to the
14072 at_suite_log when a test fails.
14073 (AT_SETUP): pipe the test case's output into at_tee_pipe,
14074 with the AS_MESSAGE_LOG_FD redirected to stdout.
14075 (AT_CLEANUP): save the output status in $at_status_file
14076 and restore it, redirect the AS_MESSAGE_LOG_FD back to
14077 its original place.
14078 (AT_CHECK): since tests are run with a redirected stdout,
14079 and used to be re-run in verbose mode, turn some $at_verbose
14080 into echo, and don't redirect the output of testing stdout
14083 * lib/autotest/autoconf.texi (testsuite Scripts): Update
14084 the name of the debugging directory and information about

14204 2003-05-06 Akim Demaille <akim@epita.fr>
14206 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
14207 longer updates aclocal.m4 if useless, (ii) if a file m4_included
14208 by aclocal.m4 is changed it might require the importing of another
14209 m4 extension file, i.e., aclocal must be run.
14211 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
14212 (&parse_args): Use --force with aclocal if required and supported.
14213 (&autoreconf_current_directory): Use &run_aclocal.

14222 open during the whole autom4te run.
14223 ($icache_file): New.
14224 (&freeze): Lock the $icache_file.
14226 2003-04-29 Derek Price <derek@ximbiot.com>
14228 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
14229 seperator with m4_append_uniq(). It doesn't work.
14230 (AT_CLEANUP): Add `;' to end of at_help_all.
14231 (AT_INIT): Allow --keywords to be specified more than once. When
14232 grepping $at_help_all for keywords, use the field and keyword
14233 seperators to ensure a complete keyword match. Alter at_prev handling
14234 to support the new --keywords behavior.
14236 2003-04-27 Karl Berry <karl@freefriends.org>
14238 * doc/autoconf.texi: Make the dir entries in the autoconf manual
14239 align better with others. I also made some of the individual
14240 entries on one line, for brevity and to make it easier for me to
14241 sort my dir-example file in the Texinfo distribution :).

14308 header causes problems.
14310 2003-03-28 Akim Demaille <akim@epita.fr>
14312 * tests/torture.at (Configuring subdirectories): Require aclocal
14313 1.4, otherwise the test fails, as it does support configure.ac.
14314 This fixes the "test 40 failed" bug reports.
14316 2003-03-28 Akim Demaille <akim@epita.fr>
14318 * doc/autoconf.texi (C Compiler): `#line' portability.

14336 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
14337 obsolete AC_HELP_STRING.
14338 (AC_HELP_STRING): AU_DEFUN to...
14339 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
14340 * tests/m4sh.at (AS_HELP_STRING): New test.

14344 2003-03-26 Derek Price <derek@ximbiot.com>
14346 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
14347 sense. Verbosify the diversion definitions comment.

14385 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
14386 Tru64 make in the "target lookup" section.
14387 (Automake): Automake 1.5+ no longer requires special tools to be
14388 present on the developer's host.
14390 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
14392 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
14393 to a shell that can handle redirection or quoting correctly.

14399 * bin/autoupdate.in (BEGIN): Likewise.
14400 * bin/ifnames.in (BEGIN): Likewise.
14402 * bin/ifnames.in: Add final newline to help and version messages.
14404 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
14405 to cope with DOS-style absolute paths, when constructing
14408 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
14409 When constructing paths with IFS=:, quote the path. If we're
14410 constructing a DOS-style absolute path, we don't want to split it
14413 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
14416 2003-02-25 Pavel Roskin <proski@gnu.org>
14418 * bin/autoheader.in: Add missing newline when printing

14424 2002-09-01 patch by replacing "test -n" with "test -z".
14425 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
14426 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
14428 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
14429 to fix a mismatch between example and discussion.
14431 2003-02-24 Kevin Ryde <user42@zip.com.au>
14433 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
14434 format starting with "-".
14436 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
14438 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
14439 is not portable inside Makefile.
14441 2003-02-20 Akim Demaille <akim@epita.fr>
14443 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
14444 compiler says yeah, but preproc says nope, compiler is right.
14445 Conversely, prompt the reader to send a bug report to the
14446 maintainers of the package, not of Autoconf.
14448 2003-02-20 Klee Dienes <kdienes@apple.com>
14450 * bin/autoreconf.in (autoreconf_current_directory): Properly
14451 handle an empty aclocal.m4.

14456 $ac_prefix_program.
14459 2002-12-23 Paul Eggert <eggert@twinsun.com>
14461 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
14462 innocuous variant befor including <limits.h> or <assert.h>. This
14463 works around a bug reported by Albert Chin: HP-UX 11i
14464 (and earlier versions) have a <limits.h> that declares
14465 gettimeofday and many other functions.
14467 2002-12-03 Paul Eggert <eggert@twinsun.com>
14471 * NEWS, configure.ac: Update version.
14473 * doc/fdl.texi: Upgrade to FDL version 1.2.
14475 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
14476 nontrivially in main's body, so that f's external declaration is
14477 not optimized away in AIX. This should fix the bug reported by
14479 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
14481 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
14482 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
14483 defined, to support freestanding compilers. This should fix the
14484 bug reported by Momchil Velkov in
14485 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
14487 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
14488 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
14489 obsolete AC_CHECK_TYPE. The missing empty arg was reported

14491 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
14493 * Makefile.maint (www-gnu): New macro.
14494 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
14495 the location has moved.
14497 2002-12-02 Martin Frydl <martin@systinet.com>
14499 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
14500 \(.*\) match is too long and there is something more to be checked.
14501 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
14503 2002-11-15 Akim Demaille <akim@epita.fr>

14519 Update from masters.
14521 2002-11-14 Akim Demaille <akim@epita.fr>
14523 * Makefile.maint: Sync with Bison, i.e.:
14524 (po-check): Scan .l and .y files instead of the
14525 .c and the .h files that they generate. This fixes the bug
14526 reported by Tim Van Holder in:
14527 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
14528 Look for N_ as well as for _. Try to avoid matching #define for
14532 2002-11-14 Akim Demaille <akim@epita.fr>
14534 * doc/autoconf.texi (C Compiler): Compiling several files at once.
14535 From Paul Eggert and Albert Chin-A-Young.
14537 2002-11-14 Akim Demaille <akim@epita.fr>
14539 * doc/autoconf.texi (C Compiler): Solitary backslashes.
14540 From Paul Eggert and Albert Chin-A-Young.
14542 2002-11-14 Kevin Ryde <user42@zip.com.au>
14544 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
14545 than assigning in main, to avoid HP cc +O3 optimizing it away.
14547 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
14549 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
14550 option. Process --recheck after parsing all options. Pass -q
14551 option to configure on --recheck.
14552 (AC_OUTPUT): Pass -q from configure to config.status.
14553 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
14554 arguments to record.
14555 * doc/autoconf.texi (config.status Invocation): Document
14556 config.status -q option.
14558 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
14560 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
14561 Makefile.in if Makefile.am exists.
14562 (output): Strip `.am' from Makefiles. Don't
14563 output AC_CONFIG_FILES if no Makefiles were found.
14565 2002-11-07 Akim Demaille <akim@epita.fr>
14567 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
14568 (local_updates): New.

14570 (local_updates): New.
14572 2002-11-06 Akim Demaille <akim@epita.fr>
14574 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
14575 declaration in extern "C" too.
14576 Reported by Roberto Bagnara.

14583 Reported by Ezra Peisach.
14585 2002-11-05 Akim Demaille <akim@epita.fr>
14587 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
14589 We _have_ to stop using the old compatibility scheme that tried to
14590 avoid useless backslashes because Libtool 1.4.3 contains a
14591 AC_DEFINE([error_t], [int],
14592 [Define to a type to use for \`error_t' if it is not
14593 otherwise available.])
14594 We _have_ to quote the single quote and backslashes with \. The
14595 old compatibility scheme saw that ` was backslashed, and therefore
14596 did not quote the single quote. Hence before this patch, Autoconf
14597 was not compatible with Libtool.
14599 2002-11-04 Paul Eggert <eggert@twinsun.com>
14601 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

14618 (&autoreconf): here.
14619 ($help, $make, &parse_args, &autoreconf_current_directory):
14621 * doc/autoconf.texi (autoreconf Invocation): Adjust.
14623 2002-10-31 Bruno Haible <bruno@clisp.org>

14637 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
14639 2002-10-31 Akim Demaille <akim@epita.fr>
14641 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
14642 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
14643 Make variable, not a shell variable.
14644 Suggested by Bruno Haible.
14646 2002-10-31 Akim Demaille <akim@epita.fr>
14648 * bin/autom4te.in (load_configuration): Reject #args out of any
14651 2002-10-31 Akim Demaille <akim@epita.fr>
14653 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
14654 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
14655 (_AC_RUN_IFELSE): Use it.
14656 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):

14663 * bin/autom4te.in (&parse_args, $help): Support --no-cache.
14664 * doc/autoconf.texi (autom4te Invocation): Adjust.
14665 Suggested by Tim van Holder.
14667 2002-10-29 Paul Eggert <eggert@twinsun.com>
14669 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
14670 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
14671 Problem reported by Bruno Haible.
14673 2002-10-29 Akim Demaille <akim@epita.fr>
14675 * doc/autoconf.texi (Header Templates): Put also in words what the
14676 pictures says to assist free style readers.
14677 (Customizing autom4te): s/--cache=/--cache /.
14679 2002-10-29 Akim Demaille <akim@epita.fr>
14681 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and

14988 Reported by Alexandre Duret-Lutz.
14990 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

15010 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
15011 if some file was changed instead of `print'.
15012 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

15047 From Sam Varshavchik.
15049 2002-10-08 Akim Demaille <akim@epita.fr>
15051 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
15052 aclocal invocation, as Gettext macros might not be visible to
15054 Instead of blindly running autopoint, scan configure.ac (not the
15055 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
15056 Reported by Paul D. Smith.
15058 2002-10-08 Paul Eggert <eggert@twinsun.com>

15088 * tests/torture.at (Configuring subdirectories): Be robust to

15138 tracking changes in autoscan.list.
15139 * lib/autoscan/autoscan.list (function): Strip comments, sort.

15187 the tmpdir must be created.
15188 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
15189 dir be in the build tree, instead of $TMPDIR.
15191 2002-09-27 Akim Demaille <akim@epita.fr>
15193 * bin/autoscan.in: Improve the comments.
15194 (&parse_args): Drop obsolete undocumented options.

15203 * doc/autoconf.texi (autoreconf Invocation): Likewise.
15205 2002-09-26 Akim Demaille <akim@epita.fr>
15207 Single suffix rules and seperated dependencies are not portable.
15209 * doc/autoconf.texi (Installation Directory Variables): Update.
15210 (Limitations of Make): Some about `Single Suffix Rules and
15211 Separated Dependencies'.
15212 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
15213 (ifnames, autoscan, autom4te): Un-factor into several rules.
15215 2002-09-25 Paul Eggert <eggert@twinsun.com>
15217 * BUGS (Interoperability bugs): New section. Mention libtool
15218 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
15220 2002-09-24 Paul Eggert <eggert@twinsun.com>
15222 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
15223 make handles suffix-rules differently from GNU make.
15225 * bin/Makefile.am (SUFFIXES, .in): Remove.
15226 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
15227 Move the body of the old .in rule here.
15229 2002-09-16 Akim Demaille <akim@epita.fr>
15231 i960 compilers create `b.out' files by default.
15232 Reported by Ralf Corsepius.
15234 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
15235 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
15237 2002-09-13 Paul Eggert <eggert@twinsun.com>
15239 * doc/autoconf.texi (Particular Headers): Remove obsolete
15240 reference to `struct timezone' in the description of

15247 * config/config.sub, config/config.guess: Update.
15248 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
15249 * Makefile.am: Adjust.
15251 2002-09-13 Akim Demaille <akim@epita.fr>
15253 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
15254 reading config.log when the compiler is rejected.
15255 Suggested by Guido Draheim.
15257 2002-09-13 Akim Demaille <akim@epita.fr>
15259 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
15260 (chdir_init) might hang when stat'ing mounted directories.
15261 Reported by Vance Shipley.
15263 2002-09-12 Akim Demaille <akim@epita.fr>
15265 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
15268 2002-09-12 Akim Demaille <akim@epita.fr>
15270 * doc/autoconf.texi (Defining Symbols): Present two different
15271 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
15272 difference between 1 argument calls, and 2-3 argument calls.
15274 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
15276 * doc/autoconf.texi: Review grammar and punctuation.
15278 2002-09-11 Paul Eggert <eggert@twinsun.com>
15280 * doc/autoconf.texi: Fix minor formatting, spelling, and
15282 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
15283 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
15286 2002-09-11 Akim Demaille <akim@epita.fr>
15288 * doc/autoconf.texi (Questions): Rename as...
15290 (Defining Directories): New.
15292 2002-09-09 Akim Demaille <akim@epita.fr>
15294 * doc/autoconf.texi (Making testsuite Scripts): Update.
15295 Suggested by Nishio Futoshi.
15297 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
15299 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
15300 plain `@' is wanted.
15302 2002-09-09 Akim Demaille <akim@epita.fr>
15304 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
15305 `duplicates', since the algorithm was too naive and could keep
15306 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
15307 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
15308 Reported by Ralf Corsepius.
15309 * tests/torture.at (Configuring subdirectories): Exercise these
15312 2002-09-09 Akim Demaille <akim@epita.fr>
15314 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
15315 looking for a replacement file.
15316 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
15317 directory is relative.
15318 * doc/autoconf.texi (Generic Functions): Clarify the replacement
15319 directory definition.
15320 Reported by Andreas Schwab and Jim Meyering.
15322 2002-09-06 Akim Demaille <akim@epita.fr>
15324 * doc/autoconf.texi (Setting Output Variables): Clarify what
15325 precious variables are.
15326 Suggested by Pontus Skoeld.
15328 2002-09-05 Akim Demaille <akim@epita.fr>
15330 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
15331 (ifnames, autoscan, autom4te): Since we don't only depend on
15332 configure.ac variables (such as VERSION etc.), but also on prefix
15333 and so forth, depend on Makefile, not configure.ac.
15334 Reported by Alexandre Duret-Lutz.
15335 * doc/autoconf.texi (Installation Directory Variables): Adjust.
15337 2002-09-05 Kevin Ryde <user42@zip.com.au>
15339 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
15340 doesn't seem to be confined to ia64, just say "some versions".
15342 2002-09-04 Akim Demaille <akim@epita.fr>
15344 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
15346 * Makefile.am (maintainer-clean-local): Remove.
15347 (MAINTAINERCLEANFILES): Remove COPYING.
15349 2002-09-03 Paul Eggert <eggert@twinsun.com>
15351 * doc/autoconf.texi (Configuration Commands): Remove obsolete
15352 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
15355 2002-09-03 Akim Demaille <akim@epita.fr>
15357 * configure.ac: Bump to 2.53d.
15358 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
15359 as of today, on Automake's team suggestion.
15361 2002-09-03 Akim Demaille <akim@epita.fr>
15365 2002-09-02 Akim Demaille <akim@epita.fr>
15367 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
15369 * configure.ac: Disable SITE_MACRO_DIR.
15371 2002-09-02 Jim Meyering <meyering@lucent.com>
15373 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
15374 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
15375 Also, tweak grammar: s/make sure to/be sure to/.
15377 2002-09-02 Paul Eggert <eggert@twinsun.com>
15379 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
15380 directory names are generally preferable to physical names.
15382 2002-09-02 Akim Demaille <akim@epita.fr>
15384 * lib/Autom4te/General.pm (&update_file): s/die/error/.
15385 Reported by Raja R. Harinath.
15386 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
15387 * bin/autoupdate.in: Use error instead of die.
15389 2002-09-01 Paul Eggert <eggert@twinsun.com>
15391 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
15392 ordinary shell concatenation rather than echo+tr+sed command that
15393 runs afoul of a long-line-related sed bug in Solaris 8.
15395 * bin/autoheader.in (parse_args): --warning -> --warnings.
15397 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
15398 stdout, as traditional "ls" does.
15399 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
15400 _AC_COMPILER_EXEEXT_O): Likewise.
15401 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
15403 * bin/autoconf.as: Add --prepend-include option. This patch was
15404 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
15405 but bin/autoconf.in is generated automatically from bin/autoconf.as.
15407 * bin/autoconf.in, configure: Regenerate.
15409 * doc/autoconf.texi (Special Shell Variables): Mention
15410 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
15412 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
15413 MAILPATH and set PS1, PS2, PS4 to default values, to work
15414 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
15415 For LC_ALL etc, first try to set to "C" as POSIX requires and as
15416 the Autoconf documentation specifies; fall back to "unset" only if
15417 this fails. Use a shell for-loop for this rather than an m4 loop,
15418 to shorten the output script.
15420 2002-08-30 Paul Eggert <eggert@twinsun.com>
15422 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
15423 1003.1-2001's requirements for CDPATH. Give a simpler workaround
15424 for the CDPATH problem. Document PWD.
15425 (Limitations of Builtins): Document the problem that "cd $foo" and
15426 "ls $foo" may refer to different directories in shells conforming
15427 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
15428 example, since the old example is now out of date.
15430 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
15431 FOO" and "ls FOO" talk about different directories; this catches
15432 problems when POSIX 1003.1-2001 "cd" fails due to symlink
15435 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
15436 of rolling our own unset.
15437 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
15438 in practice we needn't worry about CDPATH if unset doesn't work.
15440 * Makefile.in, aclocal.m4, bin/Makefile.in,
15441 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
15442 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
15443 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
15444 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
15445 tests/Makefile.in: Regenerate with Automake 1.6.3.
15447 * config/config.guess, config/config.sub, config/mkinstalldirs:
15450 * configure: Regenerate with self.
15452 2002-08-30 Kevin Ryde <user42@zip.com.au>

15462 2002-08-29 Akim Demaille <akim@epita.fr>
15464 * lib/Autom4te/General.pm (&xqx): New.
15465 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
15466 hand, which is not portable.
15468 * bin/autom4te.in: Use them.
15469 Use &error instead of die.
15470 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
15473 2002-08-17 Paul Eggert <eggert@twinsun.com>
15475 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
15476 default list of compilers to try, since it was long ago superseded
15477 by the ksh fc builtin. Suggested by Steven G. Johnson.
15479 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
15481 * doc/autoconf.texi (Invoking autom4te): End the option table,
15482 fixing a bug introduced by the previous patch.
15483 (Limitations of Make): Add a 'target lookup' subentry in the
15484 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
15486 2002-07-29 Mark D. Roth <roth@feep.net>
15488 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
15489 options and use $AUTOM4TE_PATH.
15490 * doc/autoconf.texi: Remove documentation of autom4te
15491 --include-envvar and --site-macro-subdir options and document
15492 use of $AUTOM4TE_PATH.
15493 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
15494 arguments from each language section.
15496 2002-07-29 Paul Eggert <eggert@twinsun.com>
15498 * doc/install.texi: Include copyright symbol in copyright notice.
15500 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
15502 (AM_MAKEINFOFLAGS): New macro.
15503 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
15504 * Makefile.am (INSTALL): Use the new macros.
15505 Use -o rather than --output, since "missing" does not grok --output.
15507 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
15509 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
15510 comments do not always work. Never trust the exit status of
15513 2002-07-24 Kevin Ryde <user42@zip.com.au>
15515 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
15516 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
15518 2002-07-23 Paul Eggert <eggert@twinsun.com>
15520 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
15521 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
15522 apparently treats PATH="nonexistent" as if it contained ".".
15523 Bug reported by Stefan `Sec' Zehl.
15525 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
15527 * doc/autoconf.texi (Limitations of Make): Mention the special
15528 handling of the obj/ directory by BSD make.

15574 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
15575 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
15576 latter was not run.
15578 2002-07-17 Akim Demaille <akim@epita.fr>
15580 * lib/Autom4te/General.pm (find_file): Browse the directories in
15581 the order they are given.

15797 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
15798 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
15799 Both macros now accept an optional source-dir arg.
15800 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
15802 * NEWS: Document this.
15803 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
15805 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
15806 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
15807 not for GNU extensions; this undoes part of the 2000-11-03 change,
15808 reverting to 2.13-compatible behavior.

15816 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
15817 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,

15819 Bug reported by Stephen Gildea.
15821 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
15822 If prototypes are supported, use them to check this at compile-time,
15823 instead of trying to check it at run-time. If we must do a run-time
15824 check, assume that setvbuf is standard when cross-compiling, as
15825 nonstandard setvbuf occurs only on ancient and unlikely hosts.
15826 Bug reported by Paul D. Smith.
15828 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
15829 argument specifying location of getloadavg.c. This removes a
15830 FIXME. This idea was taken from Jim Meyering's implementation in
15832 * doc/autoconf.texi (Particular Functions): Document this.
15833 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
15834 that's what the code does; this fixes a bug reported by

15840 autopoint instead of gettextize.
15841 ($uses_alocal): Rename as...
15842 ($uses_aclocal): this.
15843 * doc/autoconf.texi (autoreconf Invocation): Adjust.

15850 2002-04-29 Paul Eggert <eggert@twinsun.com>
15852 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
15853 files to be 1 second older; just set them to be the same time.
15854 Also, sleep 1 second after the first aclocal, to work around
15855 problems with sub-second time stamps on the input files.
15857 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
15859 * doc/autoconf.texi: Mention "set -e -x" lossage

15868 2002-04-29 Akim Demaille <akim@epita.fr>
15870 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
15871 of lack of $LINENO support, then the test will compare the $LINENO
15872 in testsuite vs. the lineno in the test file. This is wrong, of
15874 Be sure to protect it.
15875 Reported by Patrick Welche.
15877 2002-04-25 Akim Demaille <akim@epita.fr>
15879 * doc/autoconf.texi (Obsolete Macros): Typo.
15880 Reported by Vladimir Volovich.
15882 2002-04-25 Akim Demaille <akim@epita.fr>
15884 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
15885 than some of the input files, hence, on the second run of aclocal,
15886 if some of its input are younger, make them older.
15887 Suggested by Paul Eggert.
15889 2002-04-25 Akim Demaille <akim@epita.fr>
15891 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

15900 (_AC_INIT_PREPARE): Use them to log them.
15901 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
15902 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
15903 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
15904 _AC_SUBST_FILES and _AC_SUBST_VARS.
15905 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
15907 2002-04-24 Akim Demaille <akim@epita.fr>
15909 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
15910 autoheader, so that automake does not complain about a missing

16151 about VPATH, overriding of macros in sub-makes, and handling of
16154 2002-03-21 Paul Eggert <eggert@twinsun.com>
16156 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
16157 problem with here-document buffer boundaries.
16159 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
16160 when reinvoking the shell, to work around problems with installers
16161 who put strange things like "cd" commands in their environments.
16163 2002-03-19 Akim Demaille <akim@epita.fr>
16165 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
16168 2002-03-19 Akim Demaille <akim@epita.fr>
16170 * bin/autoscan.in (scan_file): Specify the location in `&used'
16174 2002-03-19 Akim Demaille <akim@epita.fr>
16176 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
16177 From Nishio Futoshi.
16179 2002-03-19 Akim Demaille <akim@epita.fr>
16181 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
16183 2002-03-18 Paul Eggert <eggert@twinsun.com>
16185 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
16186 (Limitations of Usual Tools): Add mkdir section.
16188 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
16189 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
16190 back on AS_DIRNAME to compute prefixes otherwise; this is
16191 roughly what mkinstalldirs does. That way, we need not have
16192 our own filename disassembler. The old disassembler did not
16193 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
16195 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
16196 Create at_test_all by a series of assignments,
16197 not by a single assignment of a long string. The latter causes ksh
16198 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
16199 presumably because of a buffer overrun.
16201 2002-03-14 Paul Eggert <eggert@twinsun.com>
16203 * lib/autotest/general.m4 (at_times_skip):
16204 Renamed from at_times. Now a boolean.
16205 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
16206 says 'times: not found'.

16210 * bin/autoreconf.in (&study_gettextize): New.
16211 (&autoreconf): Handle newest gettextize.

16253 2002-03-08 Akim Demaille <akim@epita.fr>
16255 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
16256 aliases the actual variables, and modifications of the former
16259 2002-03-08 Akim Demaille <akim@epita.fr>
16261 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
16262 because of C-c: have m4 output in tmp files, then mv them.

16296 * doc/autoconf.texi (Transforming Names): Equality between target
16297 and host is irrelevant.
16298 (Specifying Names, Canonicalizing): Remove all references to the
16299 backward compatibility hooks. Rather, collect them all into...
16300 (Hosts and Cross-Compilation): this new section.
16301 * doc/install.texi (System Type): Ditto.
16302 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
16303 that `--host' implies cross-compilation.
16305 2002-03-04 Akim Demaille <akim@epita.fr>
16307 * doc/autoconf.texi (Evaluation Macros): New.
16308 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
16310 (_m4_foreach): Define the variant with immediate evaluation so
16311 that it contains exactly the items, not an expression which
16312 evaluation is the current item.
16313 (m4_re_string, m4_re_word): Don't over quote them.
16315 2002-03-04 Akim Demaille <akim@epita.fr>
16317 Instead of having stacking `shift's evaluated at the end, let
16318 `foreach' loops immediately evaluate them.
16320 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
16321 $*. This is the n-th time I change my mind, but hopefully this is
16324 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
16326 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
16327 it was only a hack for m4_text_wrap.
16328 (m4_car2): Remove, replaced by...
16330 (_m4_foreach): Adjust.
16331 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
16332 m4_bpatsubst for clarification.

16384 AC_PREFIX_PROGRAM fails with dashed program names
16386 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

16423 2002-02-05 Akim Demaille <akim@epita.fr>
16425 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

16448 optional are the sum of the previous files on the command line'.
16449 Also, pass `--reload-state=' on them, so...
16450 (handle_m4): don't.

16452 (M4sh): Rely on M4sugar.

16490 2002-01-28 Akim Demaille <akim@epita.fr>
16492 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
16493 AUTOTEST_PATH *after* it was set.
16494 Don't put `.' in the PATH: the user should be precise and `./' if
16495 needed. In addition, given that the test suite does some `cd', if
16496 `.' is in the path, the `tested programs' sections will report
16497 programs found in the test suite's directory, while during the
16498 tests (performed in their own directory), these programs are no
16499 longer visible. In other words, the results is confusing and

16548 Autoconf::General::getopt with non valid options.

16552 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

16570 * tests/Makefile.am (package.m4): New.
16571 EXTRA_DIST it since its a source.
16573 2002-01-06 Akim Demaille <akim@epita.fr>

16576 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
16577 and PACKAGE_BUGREPORT from here...
16578 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
16580 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
16581 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
16582 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
16583 * tests/tools.at (autoheader): Adjust.

16607 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
16608 trailing files, don't apply `-rf' to files which might not be
16609 created by configure (core, core.*, and *.core), but just `rm -f'.
16610 Suggested by Jonathan Kamens.
16612 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

16652 Split the input line on spaces and then look for tokens.
16653 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison

16663 In particular autoscan and autoheader want -I.
16664 * configure.ac: Adjust.
16665 * lib/autoscan/headers: errno.h is portable.
16667 2001-11-26 Akim Demaille <akim@epita.fr>
16669 * bin/autoscan.in (used): New.
16672 2001-11-26 Akim Demaille <akim@epita.fr>
16674 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
16676 (&scan_sh_file): Remove a duplicate pattern.
16677 (&check_configure_ac): Use long options.
16678 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
16680 2001-11-26 Akim Demaille <akim@epita.fr>
16682 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
16683 Before, having a line containing the opening of a multi line
16684 comment made the whole line be ignored.
16686 2001-11-26 Akim Demaille <akim@epita.fr>
16688 * doc/autoconf.texi (Using an Autotest Test Suite): New.
16689 (testsuite Scripts): Be one of its subsection.
16690 (Autotest Logs): New.
16692 2001-11-26 Akim Demaille <akim@epita.fr>
16694 Test groups are now run two directories deeper.
16696 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
16697 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
16699 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
16700 top_srcdir, builddir and top_builddir.
16701 Use `at_*dir' relatively to the directory containing the
16702 suite, use `*dir' when relatively to the current group dir.
16704 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
16706 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
16707 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
16708 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
16711 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
16713 * doc/autoconf.texi (Using System Type): Add an example of `case
16714 $host' usage so people quit using `case $target' everywhere.
16716 2001-11-22 Akim Demaille <akim@epita.fr>
16718 * doc/autoconf.texi (Installation Directory Variables): Englishoes
16719 spotted by Jim Meyering.
16721 2001-11-16 Paul Eggert <eggert@twinsun.com>
16723 This patch implements a `long double' suggestion by Oliver Kiddle.
16725 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
16726 static, to catch errors if the value isn't known at compile-time
16727 and the compiler supports dynamic arrays. Change its name from
16728 `_array_' to `test_array' to avoid potential name clashes.
16729 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
16730 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
16731 better than double. Catch a bug in GCC 2.95.2 x86.
16732 * doc/autoconf.texi (C Compiler): Document the above.
16735 2001-11-13 Akim Demaille <akim@epita.fr>
16737 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
16739 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
16741 2001-11-13 Akim Demaille <akim@epita.fr>
16743 * lib/autotest/general.m4 (AT_INIT): After having run the test
16744 group, go back to the initial directory, not to at_suite_dir.
16746 2001-11-13 Akim Demaille <akim@epita.fr>
16748 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
16749 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
16750 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
16752 (AT_CHECK_CONFIGURE): Use absolute paths.
16753 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
16754 The problem is still the old one: there is no means in M4 (that I
16755 know about) to create a defining macro, because there is no means
16756 to create `$1' etc., therefore, the defining macro ``swallows''
16757 all the arguments meant to the defined macro.
16759 2001-11-13 Akim Demaille <akim@epita.fr>
16761 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
16762 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
16764 * tests/aclocal.m4: Remove, as it is no longer used.
16766 2001-11-13 Akim Demaille <akim@epita.fr>
16768 * lib/autotest/general.m4: Change `tests?' into `groups?' in
16769 variable names when referring to a single test group, or to
16770 `suite' when referring to the whole test suite.
16771 `at_last_test' is removed: m4 compute at_format itself.
16772 (at_stdout, at_stder1, at_stderr): New variables.
16773 (AT_CHECK): Use them.
16775 2001-11-13 Akim Demaille <akim@epita.fr>
16777 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
16779 Create `testsuite.dir/003/run' instead of `testsuite.003'.
16780 Do it as soon as a test fails, don't wait till the end of the test
16782 Don't remove $as_me.[0-9]*, since these files no longer exist.
16784 2001-11-13 Akim Demaille <akim@epita.fr>
16786 * tests/tools.at: Use absolute paths, since we are no longer run
16789 2001-11-13 Akim Demaille <akim@epita.fr>
16791 Now that tests are running in their own private dir, there is no
16792 need to list the files to remove at the end of tests groups.
16794 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
16795 (AT_data_files, at_data_files): Remove.
16796 (AT_CLEANUP, AT_DATA): Simplify.
16798 Remove the group dir if !debug && !failed.
16799 * tests/atspecific.m4: Adjust.
16801 2001-11-13 Akim Demaille <akim@epita.fr>
16803 Start a new layout for Autotest: `testsuite' creates
16804 `testsuite.dir' in which the at-check-line etc. files are to be
16805 found, and `testsuite.dir/003' where the test group 3 is run.
16807 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
16808 at_check_line_file, at_format, at_test_normalized, at_group_dir
16810 Create the directories.
16811 Use absolute paths for at- files.
16812 (AT_CHECK): Adjust.
16814 2001-11-11 Michael Matz <matz@kde.org>
16816 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
16818 (m4_car): Properly quote arguments.
16820 2001-11-13 Akim Demaille <akim@epita.fr>
16822 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
16823 with stricter rules on LIBOBJS.
16825 2001-11-12 Paul Eggert <eggert@twinsun.com>
16827 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
16828 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
16831 2001-11-12 Akim Demaille <akim@epita.fr>
16833 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
16835 2001-11-12 Akim Demaille <akim@epita.fr>
16837 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
16838 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
16839 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
16840 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
16841 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
16842 specify to what the macro should be defined (typically to 1).
16844 2001-11-12 Akim Demaille <akim@epita.fr>
16846 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
16849 2001-11-12 Akim Demaille <akim@epita.fr>
16851 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
16852 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
16853 definition used by Automake where LEX is +/- "${missing} lex" and
16854 `missing' itself contains variables.
16856 2001-11-12 Akim Demaille <akim@epita.fr>
16858 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
16859 Now that M4sh pushes BODY, the comments were output at the end of
16862 2001-11-08 Akim Demaille <akim@epita.fr>
16864 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
16865 that we can trace macros from aclocal.m4.
16866 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
16867 obsoleted, and redirect to the former anyway.
16868 Reported by Ralf Corsepius.
16870 2001-11-08 Akim Demaille <akim@epita.fr>
16872 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
16873 processed only if present.
16874 * tests/torture.at (Configuring subdirectories): Use autoreconf
16875 instead of successive calls to autoconf.
16876 Add a nonexistent subdirectory to exercise the patch above.
16877 Reported by Ralf Corsepius.
16879 2001-11-08 Kevin Ryde <user42@zip.com.au>
16881 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
16882 doesn't accept .S files.
16884 2001-11-07 Akim Demaille <akim@epita.fr>
16886 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
16887 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
16888 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
16889 * bin/autom4te.in (warn_forbidden): New.
16890 (handle_output): Use it.
16891 Read m4_pattern_forbid with messages.
16893 2001-11-05 Akim Demaille <akim@epita.fr>
16895 * bin/autom4te.in (--normalize): Remove.
16896 * lib/autom4te.in: Adjust.
16898 2001-11-05 Akim Demaille <akim@epita.fr>
16900 * tests/Makefile.am (testsuite): Rename this target as...
16901 ($(TESTSUITE)): this.
16904 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
16906 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
16907 the --prefix option, also remove it's argument.
16909 2001-11-05 Akim Demaille <akim@epita.fr>
16911 * doc/autoconf.texi (testsuite Invocation): Update.
16912 (Writing testsuite.at): Update.
16914 2001-11-03 Akim Demaille <akim@epita.fr>
16916 * doc/autoconf.texi: s/@code/@command/ where appropriate.
16918 2001-11-03 Akim Demaille <akim@epita.fr>
16920 * lib/Autom4te/General.pm: (&catfile, &canonfile)
16921 (&file_name_is_absolute): New, wrappers around routines from
16923 Use and export them.
16924 (&find_configure_ac): Optionally take a directory where to look at.
16925 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
16927 Default @ARGV to `.', not find_configure_ac.
16928 (&autoreconf): Argument is a directory.
16929 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
16930 * doc/autoconf.texi (autoreconf Invocation): Update.
16932 2001-11-03 Akim Demaille <akim@epita.fr>
16934 * lib/Autom4te/General.pm (@export_vars, @export_subs)
16935 (@export_forward_subs): New.
16936 Add basename, dirname, and fileparse.
16938 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
16939 Don't look for aclocal flags if we already know aclocal is not
16941 Move aclocal.m4t only if it exists.
16942 Reported by Ezra Peisach.
16944 2001-11-03 Akim Demaille <akim@epita.fr>
16946 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
16947 passed on command line, defaulting to ./configure.ac if present.
16948 (&maybe_autoreconf, File::Find): Remove, unused.
16949 (&autoreconf): If autoconf is not used, don't try to trace.
16951 2001-11-02 Akim Demaille <akim@epita.fr>
16953 * configure.ac: Bump to 2.52g.
16955 2001-11-02 Akim Demaille <akim@epita.fr>
16959 2001-11-02 Akim Demaille <akim@epita.fr>
16961 * config/config.guess, config/config.sub, doc/standards.texi:
16962 * config/lispdir.m4: Update from masters.
16963 * configure.ac: Bump to 2.52f.
16965 2001-11-02 Akim Demaille <akim@epita.fr>
16967 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
16968 Don't run aclocal when aclocal.m4 is not from aclocal.
16970 Don't run libtoolize and gettextize if --install is not given.
16972 2001-11-01 Paul Eggert <eggert@twinsun.com>
16974 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
16975 be invoked before _AS_LINENO_PREPARE.
16976 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
16977 than character ranges.
16979 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
16980 invoking AS_BASENAME. Set the locale variables to 'C' if
16981 possible, as POSIX requires this to get the traditional
16983 * doc/autoconf.texi (Special Shell Variables): Describe the above.
16985 2001-10-31 Paul Eggert <eggert@twinsun.com>
16987 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
16988 with {}, as that triggers a bug in Bash 2.05.
16990 (_AS_LINENO_PREPARE): Use Sed rather than
16991 Awk. Fix the sed prepass to work even if there are multiple
16992 instances of $LINENO on the same line. Do not substitute for
16993 other variables like $LINENOT. Do not check file dates; such a
16994 check is unreliable on sufficiently fast machines, and removing
16995 the check makes the code simpler and more reliable. Check for
16996 output and chmod failures.
16998 * doc/autoconf.texi (Special Shell Variables): Document
17001 2001-10-31 Akim Demaille <akim@epita.fr>
17003 * tests/Makefile.am (atconfig): Remove this target, Automake
17006 2001-10-31 Akim Demaille <akim@epita.fr>
17008 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
17009 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
17010 provided, while it is optional.
17011 * configure.ac: Adjust.
17013 2001-10-26 Paul Eggert <eggert@twinsun.com>
17015 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
17016 lib/Autom4te/Struct.pm:
17017 Require Perl 5.005_03 instead of just 5.005, as some tests fail
17020 * doc/autoconf.texi (Special Shell Variables): Document some
17021 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
17023 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
17024 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
17025 eval $LINENO is not portable in practice.
17027 2001-10-24 Akim Demaille <akim@epita.fr>
17029 * lib/Autom4te/General.pm (backname): New.
17031 2001-10-24 Akim Demaille <akim@epita.fr>
17033 * m4/: Remove, merged into...
17036 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
17038 * doc/autoconf.texi (Shellology): Mention the problems with bash
17039 2.05's use of ANSI quoting in its `set' builtin.
17041 2001-10-22 Paul Eggert <eggert@twinsun.com>
17043 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
17044 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
17045 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
17046 POSIX decided to standardize on the int flavor of strerror_r.
17047 Always do char* test, as there's no reason not to.
17048 Assign to a char* var, to catch strerror_r that returns int*.
17050 * doc/autoconf.texi (Particular Functions):
17051 Document the above changes. Also, document the fact that
17052 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
17054 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
17056 2001-10-20 Akim Demaille <akim@epita.fr>
17058 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
17059 the executable was missing from the log.
17061 2001-10-20 Akim Demaille <akim@epita.fr>
17063 * lib/Autom4te/General.pm (&update_file): If destination is
17064 unchanged, remove the source.
17065 (&up_to_date_p): Don't be verbose, be debug.
17066 * bin/autoreconf.in: No longer support --m4dir.
17067 (&autoreconf): Display the full path of the configure.ac we are
17069 Trace it only once.
17070 Be sure to honor --force with gettextize.
17071 Always run aclocal.
17072 * doc/autoconf.texi: Adjust.
17074 2001-10-20 Akim Demaille <akim@epita.fr>
17076 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
17078 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
17079 `intl' is already present, as it refuses unless --force.
17080 (&parse_args): Use -I, --include instead of the old Autoconf
17082 ($localdir, $autoconf_dir): Remove.
17084 (&maybe_autoreconf): New, to preserve $_ for File::Find.
17086 2001-10-19 Jens Petersen <petersen@redhat.com>
17088 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
17089 * doc/autoconf.texi (Particular Programs): Likewise.
17091 2001-10-19 Akim Demaille <akim@epita.fr>
17093 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
17094 file in @configure_input@.
17095 Don't mention `automatically' in addition to `generated'.
17096 * tests/torture.at (#define header templates): Adjust.
17098 2001-10-19 Akim Demaille <akim@epita.fr>
17100 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
17101 comment, explain how to install automatic mode selection.
17104 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
17106 * bin/autoreconf.in (autoreconf): Display the path to the
17107 configure.ac being studied.
17109 2001-10-18 Paul Eggert <eggert@twinsun.com>
17111 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
17112 long, to work around a bug in the HP C compiler version HP92453-01
17115 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
17116 (AS_BASENAME_EXPR): New macro.
17117 (AS_BASENAME_SED): Do not assume GNU sed semantics.
17118 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
17119 and fall back on 'sed' only if the other two fail. This makes
17120 AS_BASENAME act more like AS_DIRNAME.
17121 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
17122 contains white space.
17123 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
17124 Use AS_DIRNAME, since I think it's now DOS-friendly.
17125 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
17126 Allow "dirname //FOO" to return either / or //, as POSIX allows
17129 2001-10-10 Akim Demaille <akim@epita.fr>
17131 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
17132 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
17135 2001-10-10 Akim Demaille <akim@epita.fr>
17137 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
17138 m4_define, since...
17139 (_AS_ECHO_N): AS_REQUIREs it.
17141 2001-10-10 Akim Demaille <akim@epita.fr>
17143 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)
17144 (AC_INCLUDES_DEFAULT): Move to...
17145 * lib/autoconf/headers.m4: here.
17146 * lib/autoconf/types.m4: Comment changes.
17147 * doc/autoconf.texi: Specify where the default includes are used
17148 in the macro prototypes.

17590 Do not pass a first argument with leading '-'
17591 to expr, by parenthesizing initial integers that might be negative.
17593 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
17594 now merely checks whether it is an error to pass an argument
17597 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
17598 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
17599 whether it is a (compile-time) error to pass an argument to
17600 getpgrp. This simpler test supports the revised documentation,

17617 Add test for AS_BASENAME.
17618 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
17619 added test. It now correctly handles /1/2/3/, returning '3' not ''.
17620 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
17621 * tests/base.at: Fixed the expected responses. The old ones were
17623 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
17624 the documentation claims it should (and how it behaved in 2.13).
17626 2001-09-18 Akim Demaille <akim@epita.fr>
17628 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
17629 the AC_CONFIG_COMMANDS invocation.
17630 This also solves the name clash problems.
17631 Don't set the package's ID.
17632 * lib/m4sugar/Makefile.am (version.m4): Revamp.
17633 No longer to be shipped.
17634 (version.in): Remove.
17635 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
17636 * lib/autoconf/status.m4: Adjust.
17637 Use `m4_PACKAGE_STRING'.
17638 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
17639 the only optional argument is the name of the test suite.
17640 Expect `package.m4' to define the package signature.
17641 * lib/autom4te.in (Autotest): Add `package.m4?'.
17642 * tests/Makefile.am (package.m4): New.
17643 * tests/suite.at: ifnames is a victim.
17645 2001-09-18 Akim Demaille <akim@epita.fr>

17648 AC_LIBSOURCE, AC_CONFIG_FILES.

17656 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
17657 Allow expression to return any value that can fit into unsigned long
17658 (not int, as before). Check for output errors.
17660 2001-09-17 Bruno Haible <haible@ilog.fr>
17662 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
17663 Always include <stdio.h> and <stdlib.h>. Evaluate
17664 the expression in an extra function before these includes. Call
17665 fprintf "%d" only after ensuring the argument is of type 'int'.
17666 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
17668 2001-09-17 Paul Eggert <eggert@twinsun.com>
17670 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
17671 or CFLAGS=-O5. In that case, the linker has a relaxed view of
17672 fatal errors, and AC_CHECK_LIB causes it to include libraries even
17673 when they don't exist.
17675 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
17676 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
17679 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
17680 version with the version used by fileutils 4.1, except use
17681 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if

17726 * lib/autotest/general.m4 (AT_INIT): Create and remove
17727 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
17728 test suites can cohabit.

17732 * tests/mktests.sh: Don't output banners for empty test files.

17784 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

17787 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

17831 to avoid GCC warnings.
17834 2001-09-05 Akim Demaille <akim@epita.fr>

17838 2001-09-05 Akim Demaille <akim@epita.fr>
17840 Be ready to handle filenames as stupid as `dnl.at', for if even
17841 the maintainer is dumb enough to do that...
17843 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
17844 excellence in M4 quotation: consider `__file__' is active.
17846 And BTW, when invoking m4, pass the --include in the right order:
17849 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

17877 New, extracted from main.
17878 Use IO::File wherever possible.

17911 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
17912 (testsuite Scripts): There is no such thing as `atconfig.in'.

17917 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
17920 2001-08-31 Akim Demaille <akim@epita.fr>

17923 to m4sugar was lacking!
17925 2001-08-31 Akim Demaille <akim@epita.fr>
17927 * man/Makefile.am (.x.1): We really have to pass
17928 autom4te_perllibdir.

17995 Map --localdir, --autoconf-dir onto it.
17996 Forward autom4te's options instead of interpreting them.
17997 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
17998 There is no such envvar since the inception of autom4te.cfg.
17999 * bin/autom4te.in (&parse_args): Uniquify `@include'.

18020 * lib/Autom4te/General.pm (&find_peer): Remove.
18021 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
18022 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
18023 * man/Makefile.am: Let help2man rely on PATH instead of trying to
18024 find the executables for it.
18025 * tests/Makefile.am: Major cleanup. Too lazy to document...
18026 * tests/atlocal.in: Remove all the obscure envvar manipulations.
18028 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
18029 indeed related to running the test suite, while passing
18030 --autoconf-dir and others is related to running non installed
18031 Autoconf executables. So don't do that, leave it to...

18033 * tests/autoscan: New.
18034 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

18050 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
18051 Suggested by Paul Eggert.
18053 2001-08-29 Akim Demaille <akim@epita.fr>
18055 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
18056 download in a tmp dir.
18058 2001-08-29 Akim Demaille <akim@epita.fr>
18060 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

18072 * bin/autoconf.in: Simplify and adjust.
18073 * tests/Makefile.am (AUTOMAKE): Use --set.
18074 * tests/atlocal.in: Adjust.

18077 2001-08-29 Akim Demaille <akim@epita.fr>
18079 * lib/autotest/general.m4: Use
18080 foo=`(command) 2>/dev/null`
18082 foo=`command` 2>/dev/null
18083 (at-devnull): Rename as...
18084 (AT-devnull): this.
18085 (--clean): Remove AT-* files too.

18597 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
18599 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
18600 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
18601 * doc/autoconf.texi (C Compiler Characteristics): Update
18602 documentation for AC_C_BIGENDIAN.
18604 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
18606 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
18607 magic values from an object file when cross-compiling.
18608 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
18610 2001-08-10 Akim Demaille <akim@epita.fr>
18612 * bin/autom4te.in (&handle_output): Don't use `grep' with side
18614 Suggested by Russ Allbery.
18616 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
18618 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
18619 current $prefix to the sub-configures.
18621 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
18623 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
18624 extension (needed on BeOS). Reported by Guido van Rossum.
18626 2001-08-09 Akim Demaille <akim@epita.fr>
18628 * bin/autom4te.in ($icache): Load it only if older than autom4te.
18630 2001-08-07 Akim Demaille <akim@epita.fr>
18632 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
18634 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
18635 No need to remove the files before and after the each test, before
18636 each test and at the end of the suite is enough.
18637 Display only the children `times', not the shell's.
18638 If the test failed or was skipped, at-times is not available.
18640 2001-08-07 Akim Demaille <akim@epita.fr>
18642 Always produce testsuite.log, including when there are no
18643 failures. This helps getting information on skipped tests, and
18644 duration of the tests. Err, implement the latter btw.
18646 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
18647 Dump information on the first run of each test.
18648 (AT_CLEANUP): Create `at-times' containing the duration of the
18651 2001-08-07 Akim Demaille <akim@epita.fr>
18653 The use of `dumpstat' revealed that `len' was used although it
18654 should not. m4_text_wrap was using it, but in the Autoconf world
18655 where it is legal. Hence (i) test M4sh in its own world, not
18656 Autoconf's, and (ii), ahem, fix the bug :)
18658 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
18659 does not like `' instead of [].
18660 (AT_INIT): Forbid `^_?AT_'.
18661 And don't output such tokens.
18662 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
18663 `script.as', and `autom4te.cache'.
18664 Remove `empty' and `macro' which are no longer used.
18665 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
18666 * tests/m4sugar.at: Use it.
18667 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
18669 2001-08-07 Akim Demaille <akim@epita.fr>
18671 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
18673 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
18675 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
18677 2001-08-04 Akim Demaille <akim@epita.fr>
18679 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
18680 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
18682 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
18683 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
18684 (AC_F77_MAIN): Likewise.
18686 2001-08-04 Akim Demaille <akim@epita.fr>
18688 Don't rely on M4sugar outputting the patterns in files, since we
18689 might process the output _without_ running m4, hence without these
18692 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
18693 * bin/autom4te.in (@Request::includes): Remove, unused.
18694 (@Request::source): Rename as...
18695 (@Request::input): this.
18696 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
18697 (&handle_output): Fetch the patterns from the traces.
18698 `$forbidden' and `$allowed' are constant: use m//o.
18699 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
18700 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
18702 2001-08-04 Akim Demaille <akim@epita.fr>
18704 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
18705 autoconf', i.e., in addition to caching traces, cache the output.
18707 * bin/autom4te.in (Request::cache): Rename as...
18708 (Request::id): this.
18709 ($cache, $icache, $tcache, $ocache): New.
18710 (&handle_m4): Save M4 output in the cache instead of $tmp.
18711 (&handle_output): Adjust.
18712 (&up_to_date_p): Check that the output cache is up to date too.
18713 (top level): Run `&handle_m4' iff force or the cache is invalid.
18714 Run `&handle_output' if the output cache is more recent.
18716 2001-08-04 Akim Demaille <akim@epita.fr>
18718 * bin/autom4te.in ($force): New.
18719 (&parse_args, &print_usage): -f, --force is a new option.
18720 (&handle_output): CPP directives might have spaces after `#'.
18721 (&parse_args): The first file only can be frozen.
18723 2001-08-04 Akim Demaille <akim@epita.fr>
18725 Don't let autom4te compute the `include' traces several times:
18726 first check that the trace cache file is up to date, and then
18727 compare its timestamp with that of the output.
18729 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
18730 the preamble. Don't require 5.005 as Autom4te::General does it,
18731 and better yet (use `use', not `require'!).
18732 * lib/Autom4te/Struct.pm: Rename the last occurrences of
18733 Class::Struct as Autom4te::Struct.
18734 * lib/Autom4te/General.pm (File::stat): Use it.
18735 (&mtime): New, export it.
18736 * bin/autom4te.in: Use it.
18737 Declare `$req' is invalid if it is outdated.
18738 Don't declare it valid before saving it if something went wrong.
18740 2001-08-04 Akim Demaille <akim@epita.fr>
18742 Autom4te shall not encode Autoconf data, and preselecting traces
18743 must be proposed to the users.
18745 * bin/autom4te.in (@required_trace): Remove.
18747 (&parse_args, &print_usage): -p, --preselect is a new option.
18748 (&up_to_date_p): Adjust.
18749 * bin/autoconf.in: Preselect some Autoconf macros.
18751 2001-08-04 Akim Demaille <akim@epita.fr>
18753 * tests/tools.at (autoconf --trace: user macros): Check traces on
18754 macros invoked without arguments, and macros invoked with multiple
18757 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
18759 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
18762 2001-08-03 Akim Demaille <akim@epita.fr>
18764 * bin/autoconf.in ($@): Work around the usual sh bug.
18767 2001-08-03 Akim Demaille <akim@epita.fr>
18769 Clean up the handling of the M4 builtins tracing exception.
18771 * bin/autom4te.in (Request::request): Don't complete M4 builtins

18774 (@m4_builtin): this.
18775 (%m4_builtin_alternate_name): New.
18776 (&parse_args): Complete the trace requests with alternate names.

18788 (m4_divert_pop): Dump the whole diversion stack when a diversion
18790 * bin/autom4te.in (&handle_output): Remember of the first
18791 occurrence of a possibly undefined macro, not the last.
18792 Complain about the possibly undefined macros in the same order as
18793 the appear in the output.
18794 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
18795 * tests/tools.at (autoconf: forbidden tokens, basic)
18796 (autoconf: forbidden tokens, exceptions): No longer sort
18797 autoconf's stderr, as it is now deterministic.
18798 Check that `dnl' is caught.

18821 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
18822 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
18823 system to run `mv', `rm', and `cmp'.

18827 * lib/Autom4te/General.pm (&unique): New.
