3606 Cover more potentially problemtic file names. Use the new
3609 Properly handle funny file names for headers in config.status.
3610 The test suite did not cover this bug because the code was not
3611 quoting properly the arguments of `rm -f' (which "fails" silently)
3612 as well as the arguments of `diff' (whose output was redirected to
3613 /dev/null so we couldn't see its error message).

3731 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
3733 <DEFAULTS>: Delay computation of variables based on $at_dir...
3734 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
3735 <TESTS>: Re-invoke via absolute name, since -C may be in effect.

3753 * doc/autoconf.texi (Particular Programs): Do not mention the
3754 Autoconf version in which the AC_PROG_INSTALL change was done.
3755 Suggested by Paul Eggert.

3759 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
3760 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
3761 mode, we change to the source directory, also set $ac_pwd so we
3762 do not go back to the build tree for the next config subdir.
3763 * tests/torture.at (Deep Package): Extend test to contain two
3764 config subdirs on the top level.
3766 Fix parallel `maintainer-check'.
3767 * Makefile.am (maintainer-check-tests): Depend on `all'.
3768 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.

3818 (m4_require): Use m4_do, not m4_join.
3820 Fix some whitespace tests on cygwin.

3825 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
3827 Optimize AC_REQUIRE.

3846 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
3847 (Substitute a newline, datarootdir workaround): Likewise.
3848 (Define a newline): Adjust for linenumber changes in configure.ac.

3858 * tests/m4sh.at (LINENO): Quote $0.
3860 Fix testsuite program wrapper for whitespace in `pwd`.
3861 The problem here is that the usual mantra is that command
3862 variables can contain arguments, thus we cannot just escape
3863 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
3864 $top_builddir/tests directory early in $PATH, so that the
3865 wrappers are found by their plain name.
3866 * tests/wrapper.as: Put $testdir early in $PATH.
3867 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.

3879 <at_func_create_debugging_script, Driver Loop>:
3880 Quote $at_group_dir.
3881 * tests/autotest.at (whitespace in absolute testdir): New test.
3883 * lib/autom4te.in: Quote @datadir@.
3885 Proper file name escaping in Autoconf programs and Perl modules.
3886 This includes escaping of characters special to the shell
3887 as well as special to Perl, e.g., leading `<' or `>'.
3888 For example, when $file starts with `>', `open ">$file"'
3889 wrongly tries to append to a different file.
3890 * bin/autoconf.as: Fix quoting for autom4te options.
3891 * lib/Autom4te/General.pm (shell_quote): New function, taken
3892 from coreutils, written by Jim Meyering.

3902 test. Test twice, with special characters allowed on w32, and the
3903 rest. Test leading and trailing whitespace, for `open_quote'.
3904 (autotools and whitespace in file names): New, analogous test.

3912 (update_file, contents): Use it.
3914 * Makefile.am (autom4te-update): Rewrite for git.
3916 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3918 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
3920 Fix copyright years.

3934 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
3936 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
3937 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
3938 #undef as this runs afoul of our new way of creating config.h.

3942 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3944 Fix autom4te for unusual characters in input file names.
3945 * bin/autom4te.in (files_to_options): Quote active characters
3947 * tests/tools.at (autom4te and white space in file names):
3950 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
3951 Document that Tru64 awk always splits $0.
3953 2007-11-24 Stepan Kasal <kasal@ucw.cz>
3955 * lib/autotest/general.m4 (AT_INIT): Do not extract the
3956 `#AT_STOP_...' line at the end of each test.
3958 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3960 * lib/autotest/general.m4 (AT_INIT): For awk line number
3961 extraction script, ensure `$at_group' has a defined value
3962 even for the empty set, and properly quote its usage inside
3965 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3967 * doc/autoconf.texi (Shell Functions): New chapter. Document
3968 IRIX sh $0 issue in functions, move content from ...
3969 (Portable Shell): ... here.
3970 (Shell Script Compiler): Note that shell functions are not
3971 totally unportable any more.
3973 2007-11-22 Stepan Kasal <kasal@ucw.cz>
3974 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3976 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
3977 extracting the line numbers of the last needed test.
3979 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3981 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
3984 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3986 Fix IRIX testsuite debugging failures: $0 in functions.
3987 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
3988 Do not use $0 inside a function, as IRIX sh will set that to the
3989 function name rather than the script invocation name.
3991 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
3992 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3994 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
3995 to extract test scripts.
3996 (AT_INIT): Extract and cache test script line numbers.
3998 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4000 * lib/autotest/general.m4: Revert 2007-11-15 patch and
4001 subsequent fixups; the awk -> here-document conversion trashes
4002 performance too much with AIX sh.
4004 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4006 * tests/local.at: Do not test m4, perl with AT_TESTED.
4008 Diagnose and guard against write errors dealing with config.status.
4009 The general idea is this: all write failures from `configure'
4010 writing `config.status' are indicated by $ac_write_error, which
4011 is only checked at the end. This is safe because config.status
4012 code is not executed before the file is complete. Other write
4013 failures, be they inside config.status, or in sub shell/awk
4014 scripts spawned from configure or config.status, typically need
4015 earlier checking, as their results are used right afterwards.
4016 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
4017 before writing config.status, check afterwards.
4018 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
4019 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
4020 Set `ac_write_error' for write failures to config.status. Barf
4021 upon write failures to temporary files.
4022 Adjust note about closing and reopening the here-document.
4023 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
4024 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
4025 reopening the here-document.
4026 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4027 Ensure `ac_write_error' does not escape into config.status.
4028 Also, add a couple of code paths not yet exercised in the test
4029 suite: a config file with input from stdin, and a config header
4031 Suggestion for catching write errors by Bruno Haible.
4033 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4035 Avoid error with Tru64 awk and testsuite lines with many words.
4036 * lib/autotest/general.m4 (AT_INIT): In the awk script that
4037 reads the testsuite, set the field separator to an unusual value,
4038 in order to not run over the limit of 199 fields. Tru64 4.0D awk
4039 even splits the input if $i, i>0, was never accessed in the script.
4041 Revert 2007-10-17 change.
4042 * TODO: Multiline args in config files and headers mean something
4043 different and are not fixed, see
4044 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
4045 Report by Stepan Kasal.
4047 * doc/autoconf.texi (Generic Programs): Fix typo.
4049 2007-11-16 Stepan Kasal <kasal@ucw.cz>
4051 AC_*_TOOL does not canonicalize the prefix
4052 * doc/autoconf.texi (Generic Programs): Do not say that
4053 the *_TOOL macros canonicalize, they simply use the `host_alias'.
4055 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4057 Diagnose write errors in config.status instantiations.
4058 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
4059 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
4061 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4062 Extend test to also check for some write error failures, using...
4063 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
4064 Report by Bruno Haible.
4067 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
4069 (_AT_CHECK): Use less indentation, to save space.
4071 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4073 Add witness macro for @top_build_prefix@ substitution.
4074 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
4075 (_AC_OUTPUT_FILE): Mention it here.
4077 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
4078 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4080 * lib/autotest/general.m4 (at_func_test): Remove.
4081 (AT_INIT): Pre-extract test groups into separate files.
4082 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
4083 Remove at-test-source files together with the $at_group_dir.
4084 * tests/autotest.at (Long test source lines): New test.
4086 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4088 Shell functions and variables may share a namespace.
4089 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
4092 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
4094 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
4097 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4099 * lib/autoconf/status.m4: Fix a couple of comment typos.
4101 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
4103 2007-11-13 Jim Meyering <meyering@redhat.com>
4105 Clean up the rule to create "expr".
4106 * tests/Makefile.am (expr): Don't redirect directly to target.
4107 Redirect just once, not for each echo statement.
4108 Use $@, not literal "expr".
4110 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
4112 Don't worry about preprocessor when testing long long.
4113 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
4114 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
4115 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
4116 These no longer check for preprocessor flaws.
4117 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
4118 Do not check for preprocessor flaws.
4120 2007-11-13 Jim Meyering <meyering@redhat.com>
4122 Adapt dependencies, now that a version change doesn't modify configure.ac
4123 * GNUmakefile: Remove "make clean" kludge.
4124 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
4126 Don't redirect directly to target.
4127 Use $@, not literal "version.m4".
4129 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4131 * doc/autoconf.texi (Making testsuite Scripts): Document
4132 ":;{" shorthand as in previous patch.
4134 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
4136 * doc/autoconf.texi (Limitations of Builtins): Document problem
4137 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
4139 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
4140 Use ":;{" shorthand.
4141 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
4143 2007-11-12 Jim Meyering <meyering@redhat.com>
4145 Add more non-srcdir build support.
4146 * GNUmakefile (dummy): Split a long line.
4147 Add -v option to autoreconf invocation.
4149 Remove the autoreconf-provided INSTALL, so that we regenerate it.
4150 * GNUmakefile (dummy): Remove INSTALL.
4152 Remove racy commands to build scripts in bin/ and tests/.
4153 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
4154 are guaranteed to be built, remove the rules that tried to build
4155 them. Before, with a parallel build, these rules could lead to
4156 two processes writing tests/wrapper.in concurrently.
4158 Build in man/ only *after* building in bin/ and tests/.
4159 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
4160 in both bin/ and tests/.
4162 Accommodate non-srcdir build-from-checkout.
4163 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
4164 Use git's --git-dir=$srcdir/.git option.
4165 Add quotes, in case tarball_version_file contains shell meta-characters.
4166 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
4167 * configure.ac: Pass "." to git-version-gen.
4169 Avoid spurious test failures due to version skew.
4170 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
4172 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4174 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
4175 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
4176 Remove conftest.dSYM directory.
4177 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
4178 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
4179 Remove `conftest.*' recursively.
4180 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
4181 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4183 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
4185 Report and analysis by Jeff Squyres and Peter O'Gorman.
4187 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
4189 Fix typos in variable names.
4190 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
4192 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
4194 Document that $((expression)) is not portable.
4195 * doc/autoconf.texi (Shell Substitutions): Here.
4197 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4199 Ignore configure --help* errors due to LINENO-impaired shells.
4200 * tests/torture.at (Configuring subdirectories, Deep Package):
4201 In the --help* tests in read-only trees, make `.' temporarily
4202 writable again for the `stderr' file, and ignore errors due to
4203 the attempt to write configure.lineno.
4204 Report by Patrick Welche.
4206 2007-11-10 Jim Meyering <meyering@redhat.com>
4208 Generate package.m4 in build-dir, not srcdir.
4209 * tests/Makefile.am (package.m4): Adjust target.
4210 Don't redirect directly to $@.
4211 (CLEANFILES): Add package.m4.
4212 ($(TESTSUITE)): Depend on just-built package.m4, not the one
4214 When running $(AUTOTEST), search "." before searching $(srcdir).
4216 Avoid a race condition that would make parallel "distclean" fail.
4217 * tests/Makefile.am (distclean-generic): Replace the default,
4218 automake-provided rule with an identical one, but with an additional
4219 dependency on distclean-local. Simply adding the dependency would
4220 cause automake not to emit the rule at all.
4221 * BUGS: Building with -jN works, now.
4223 Distribute git-version-gen.
4224 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
4225 since GNUmakefile is distributed, and requires it for dist* rules.
4227 Remove two more generated files from version control.
4228 * INSTALL: Remove generated file.
4229 * lib/autoscan/autoscan.list: Remove generated file.
4231 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
4233 * GNUmakefile (PATH): Remove stray apostrophes; they become
4234 part of PATH, which isn't wanted here.
4236 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4238 New config files output variable `top_build_prefix'.
4239 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
4241 * doc/autoconf.texi (Preset Output Variables): Document it.
4243 Report by Bob Friesenhahn.
4245 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
4246 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
4247 function, to parametrize arithmetic with expr vs. the shell.
4248 Use it where possible.
4249 Suggestion by Benoit Sigoure.
4251 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
4253 Adjust the documentation of autotest WRT atlocal.
4254 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
4255 when using Automake, to write a rule to produce atlocal, since it's
4256 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
4257 distributed, not atconfig.in.
4259 2007-11-04 Eric Blake <ebb9@byu.net>
4261 Update list information.
4262 * README: Mention new autoconf-commit list.
4263 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
4265 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4267 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
4269 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
4271 * build-aux/.gitignore: Ignore mkinstalldirs.
4273 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
4275 2007-11-03 Jim Meyering <meyering@redhat.com>
4277 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
4278 * build-aux/git-version-gen: This syncs from coreutils.
4280 Adjust the build procedure so "make check" works reliably.
4281 * README-hacking: Include an extra step between "make" and
4282 "make check" to ensure that the latter passes.
4284 Use just-built tools, when possible.
4285 * GNUmakefile (PATH): Set and export here, ...
4286 (dummy): ... rather than here.
4288 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4289 and Andreas Schwab <schwab@suse.de>
4291 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
4294 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4296 * configure.ac (AC_PREREQ): Require version 2.60, for
4297 AC_PROG_SED, AC_PROG_GREP.
4299 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
4300 and Jim Meyering <meyering@redhat.com>
4301 and Andreas Schwab <schwab@suse.de>
4302 and Eric Blake <ebb9@byu.net>
4304 Document a bug in GNU Bash with compound commands and redirections.
4305 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
4306 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
4309 2007-11-03 Eric Blake <ebb9@byu.net>
4311 Support m4 1.4.5 in testsuite.
4312 * tests/torture.at (Define a newline): Exclude line numbers in
4314 Reported by Ralf Wildenhues.
4316 2007-11-03 Jim Meyering <meyering@redhat.com>
4318 Remove automake-provided files from version control.
4319 * build-aux/elisp-comp: Remove file.
4320 * build-aux/install-sh: Remove file.
4321 * build-aux/missing: Remove file.
4322 * build-aux/mdate-sh: Remove file.
4323 * build-aux/.gitignore: New file.
4324 Suggestion from Ralf Wildenhues.
4326 2007-11-03 Eric Blake <ebb9@byu.net>
4328 Adjust version comparison to account for git snapshot numbers.
4329 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
4330 component separator.
4331 * doc/autoconf.texi (Number processing Macros)
4332 <m4_version_compare>: Document this change.
4333 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
4335 2007-10-30 Bruno Haible <bruno@clisp.org>
4337 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
4338 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
4339 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
4340 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
4341 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
4342 Suggested by Paul Eggert.
4344 2007-10-28 Jim Meyering <meyering@redhat.com>
4346 * README-hacking: Autoconf, Automake, and Perl are required to build.
4347 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
4349 2007-10-28 Jim Meyering <meyering@redhat.com>
4351 README-hacking: Recommend running autoreconf -vi.
4352 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
4353 so that we use just-built tools when they're available.
4354 Suggestions from Ralf Wildenhues.
4356 2007-10-28 Jim Meyering <meyering@redhat.com>
4358 Make inter-release --version output more useful.
4360 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
4361 which indicates that it is built using the 19th change set
4362 (in _some_ repository) following the "v2.61a" tag, and that 58dd
4363 is a prefix of the commit SHA1.
4364 * build-aux/git-version-gen: New file.
4365 * configure.ac: Run it to set the version.
4366 (AM_INIT_AUTOMAKE): Don't check NEWS here.
4367 * Makefile.am (dist-hook): Arrange so that .version appears only
4368 in distribution tarballs, never in a checked-out repository.
4369 * .gitignore: Add .version here, too. Just in case.
4370 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
4371 not configure.ac, now that the version number changes automatically.
4373 Ensure that $(VERSION) is up to date for dist-related targets.
4374 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
4375 git-version-gen doesn't match $(VERSION), but only for dist targets.
4377 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4389 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
4390 * README-hacking: New file: how to build from just-checked-out sources.
4392 2007-10-23 Eric Blake <ebb9@byu.net>
4394 Improve corner case of m4_expand.
4395 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more
4397 * tests/m4sh.at (AS@&t@_HELP_STRING): Test overquoted comma.
4398 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
4401 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>

4412 2007-10-22 Eric Blake <ebb9@byu.net>
4414 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
4417 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
4419 Don't check for bug in HP-UX 11.00 cpp.
4420 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
4421 Use -1ull rather than -1u, since that causes problems with gnulib; see
4422 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

5646 AC_CHECK_TYPE, AC_CHECK_TYPES.

5649 must not be anonymous.

5651 for C++; this drops support for anonymous struct and union types,
5652 which were problematic anyway.

5672 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
5673 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
5674 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
5675 works but the latter doesn't, then it's a valid type.
5676 This lets people use function types and so forth.
5677 For C++ there doesn't seem to be a simple solution, so leave it alone.
5678 (AC_CHECK_SIZEOF): Allow argument to be a variable.
5679 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
5680 AC_CHECK_TYPE; that wasn't documented or necessary.

5737 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
5738 (Limitations of Usual Tools): Also list \< and \>, and mention that

5918 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
5920 * doc/autoconf.texi (Integer Overflow): Revised based on today's
5921 feedback. The most important changes document what happens when
5922 you convert an out-of-range value to a signed integer type, and
5923 say that (sum < a) != (b < 0) reliably detects overflow when sum =
5926 * doc/autoconf.texi (Integer Overflow): Greatly expand and
5927 rewrite, taking notions from the recent discussion on the gcc and
5928 autoconf mailing lists; please see
5929 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
5930 and follow the many links.
5931 (Integer Overflow Basics, Signed Overflow Examples):
5932 (Optimization and Wraparound, Signed Overflow Advice):
5933 (Signed Integer Division): New sections.
5935 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
5937 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
5938 preprocessor macro arguments in traced name.
5939 * doc/autoconf.texi (Defining symbols): Document longstanding
5940 support for AC_DEFINE-ing macros with arguments, and document
5941 behavior when the same variable has multiple AC_DEFINEs.
5942 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
5943 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
5944 macros directly, giving much shorter and simpler code.
5946 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
5948 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
5949 space before "$ac_configure_args" to prevent a 'config.status
5950 --recheck' failure if ac_configure_args doesn't contain a leading
5951 space. This works around a problem with the XEmacs configure.ac,
5952 which uses the (undocumented) ac_configure_args variable
5953 inconsistently with Autoconf.
5955 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
5957 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
5958 Include <limits.h>, and use its INT_MAX to rewrite the
5959 j loop so that it does not overflow 'int'. Problem reported by
5961 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
5962 Play it safe by shifting left by 1 rather than multiplying by 2,
5963 as GCC is less likely to optimize this away when the value
5964 is signed (when it assumes overflow leads to undefined behavior).
5965 Also, don't assume time_t uses two's complement.
5967 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5969 * tests/torture.at (Substitute a 2000-byte string): Avoid using
5970 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
5971 dumps core on it. Report by Tim Rice.
5973 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
5975 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
5976 --disable-option-checking to --help output even when
5977 AC_PRESERVE_HELP_ORDER is not used.
5978 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
5979 --with argument, rather than argument with [-.] replaced by
5981 * NEWS: Fix typo in previous change; the news was in the
5984 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5986 * NEWS: Warnings are now generated by default for unknown
5987 --enable-* and --with-* options.
5988 * doc/autoconf.texi (Option Checking): Renamed from
5989 (Configure Option Checking). Tighten up the wording a bit.
5990 (External Software, Package Options): Cross-reference to Option
5991 Checking, and use this to shorten our section.
5992 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
5993 "$x" to test "x$foo" != x.
5994 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
5995 Don't warn if $enable_option_checking is "no".
5996 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
5997 ac_unrecognized_opts to the empty string.
5998 Don't echo the unrecognized opts, as this might mishandle
5999 backslashes or leading -.
6000 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
6001 usage next to the other --disable-FEATURE options in the
6004 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
6006 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
6007 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
6008 Print warning for unrecognized --with and --enable options
6009 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
6010 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
6011 Disable option checking when subdirs are configured.
6012 (AC_OUTPUT): If warnings are enabled, print warning about
6013 unrecognized --with and --enable options at the end of
6014 the configure output (as well as at the beginning).
6015 * doc/autoconf.texi (Option Checking): New node.
6016 Document new option warning functionality.
6018 2006-12-16 Eric Blake <ebb9@byu.net>
6020 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
6021 * NEWS: Start news for current version.
6023 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
6025 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6026 Define HAVE_GETMNTENT to 1, not to the empty string.
6027 Problem originally reported by Jochen Friedrich in
6028 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
6030 This change prompted by a problem report by Andrey Simonenko in
6031 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
6032 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
6033 object-like macros only, in the traditional portable character
6035 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
6036 Warn about attempts to define things that are not identifiers.
6037 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
6038 awful hack that AC_DEFINEd macro names containing parentheses.
6040 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
6042 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
6043 too drastic, even if Texinfo in theory requires it for info mode.
6045 (config.status Invocation): Renamed back from Recreating a
6047 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
6048 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
6050 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6052 * NEWS: Version 2.61a.
6054 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6055 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6057 * NEWS: Document changes with echo and printf, and the lack
6058 of limits on the total size of multi-line values of substituted
6059 variables, and the AC_FUNC_FSEEKO fix.
6061 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
6063 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
6064 Writing configure.ac.
6065 (Autoconf Input Layout): Renamed from configure.ac Layout.
6066 (Recreating a Configuration): Renamed from config.status Invocation.
6067 (Obsolete Recreation): Renamed from Obsolete config.status Use.
6068 (acconfig Header): Renamed from acconfig.h.
6069 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
6070 (Writing Testsuites): Renamed from Writing testsuite.at.
6071 (Autom4te Cache): Renamed from autom4te.cache.
6073 * BUGS: Remove mention of VPATH problem, since it's now documented
6074 not to be a bug in the Autoconf build procedure itself, but rather
6075 a problem with the proprietary `make' programs.
6077 * doc/autoconf.texi (Build Directories): Add a cross reference
6080 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
6081 * doc/standards.texi: Sync from gnulib.
6083 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
6084 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
6085 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
6086 generated automatically.
6088 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
6090 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
6091 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
6092 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
6094 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6096 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
6097 `CEOF$ac_eof' special marker, the awk script cannot contain a
6098 line matching `^CEOF', so this is not needed any more.
6099 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
6100 special marker in the test.
6102 2006-12-06 Stepan Kasal <kasal@ucw.cz>
6104 * tests/tools.at (autom4te preselections): Use `find -newer';
6105 remove one of the sleeps.
6107 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
6108 more readable, using ...
6109 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
6111 * doc/autoconf.texi (autoheader Invocation): Do not double-
6112 quote the parameter of `AH_BOTTOM' in the example.
6114 2006-12-05 Stepan Kasal <kasal@ucw.cz>
6116 * doc/autoconf.texi (Configuration Headers): Remove the
6117 example with multiple input files.
6118 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
6119 multiple input files.
6121 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6123 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
6124 creating the awk substitution script, handle one input line at a
6125 time, so that the maximum length of a substituted (multi-line)
6126 value is not limited by the size of the sed pattern space.
6127 The trade-off is a slightly repetitive sed script.
6128 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
6129 can only have up to 7 characters, due to Solaris 10 /bin/sed.
6130 * tests/torture.at (Substitute a 2000-byte string): Increase the
6131 test with several long lines, they should not be caught by sed
6134 * tests/tools.at (autom4te preselections): New test, to flag
6135 entries missing from autom4te.cfg.
6136 Report by David Byron <dbyron@hheld.com>.
6138 * tests/torture.at (Substitute a 2000-byte string): Actually use
6139 AC_PROG_AWK, so the last change works as intended.
6140 (Substitute and define special characters): Likewise.
6141 (Substitute a newline): Likewise.
6143 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
6144 instead of `awk' consistently.
6145 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
6146 * tests/torture.at (Torturing config.status): Test both the
6147 result of AC_PROG_AWK and plain awk.
6148 (Substitute a 2000-byte string): Likewise.
6149 (Substitute and define special characters): Likewise.
6150 (Substitute a newline): Likewise.
6152 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
6154 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
6155 can be assigned to a function pointer. Problem reported by
6156 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
6157 part of a patch by Ralf Wildenhues in that same bug report.
6159 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
6161 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
6162 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
6164 2006-12-01 Eric Blake <ebb9@byu.net>
6166 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
6167 cross-compiling from cygwin to mingw.
6168 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
6169 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
6170 to lib/autoconf/c.m4.
6172 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6174 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
6175 string for more reliable failure. Wrap the entire test that
6176 causes the broken Solaris printf to dump core, in a subshell,
6177 so the segmentation fault message is reliably suppressed.
6178 Fix shell expansion errors by using /usr/ucb/echo always;
6179 avoid an error on systems without it by another subshell.
6180 Avoid m4 expansion of `$1'. Set the zeroth argument of the
6181 subshell-$as_echo to `as_echo', for better error message.
6183 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6185 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
6186 `BASH_SOURCE' contain a newline, set them to empty, as they may
6189 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
6191 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
6192 years and is too hard to maintain now. The last straw was
6193 reported by Jerker Baeck in
6194 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
6195 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
6196 * doc/autoconf.texi (Particular Functions): Move
6197 AC_FUNC_SETVBUF_REVERSED from here...
6198 (Obsolete Macros): ... to here. Say that it does nothing now.
6199 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
6200 Turn into (almost) a no-op.
6202 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
6204 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
6205 These macros are obsolescent and new applications shouldn't need them.
6206 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):

6213 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
6215 * doc/autoconf.texi (Setting Output Variables): Mention that
6216 @VAR1@VAR2 has unspecified behavior. Problem reported by
6218 * NEWS: Mention this.
6220 * Makefile.am: Put only a single '#' into the copyright notice,
6221 so that it's also present in the output file. Standardize wording
6222 in makefile copyright notices to match GNU coding standards.

6236 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6238 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
6239 in the sed script that mangles the awk script: delete up to the
6240 first exclamation mark only.
6241 * tests/torture.at (Substitute and define special characters):
6244 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6246 Rewrite config files generation: avoid quadratic growth in
6247 the number of substituted variables by using awk instead of sed
6248 for the bulk of the substitutions.
6249 * NEWS: Mention this.
6250 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
6251 forbidden in the output (and thus input) file.
6252 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
6253 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
6254 generate just one large awk script for substitutions,
6255 eliminating much of the earlier complexity, while adding some
6256 new complexity. Only expand the substitution templates at
6257 configure time, for smaller configure script size. If
6258 _AC_SUBST_FILES are used, test 'awk' for working getline support
6259 at config.status time. If absent, interpolate through the
6260 shell. The awk script was written with much help
6261 from Paolo Bonzini and Paul Eggert.
6262 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
6263 (_AC_SED_FRAG_NUM): Likewise.
6264 (_AC_SUBST_CMDS): Renamed from...
6265 (_AC_SED_CMDS): ...this.
6266 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
6267 * tests/torture.at (Substitute a 2000-byte string): Also
6268 substitute a line with 1000 words, and a variable with several
6270 (Substitute and define special characters): Test awk special
6271 characters, and put substitution input strings `@foo@' in the
6272 output, to test that no recursion happens; test several other
6273 combinations from Paolo Bonzini.
6275 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
6277 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
6278 that replaced echo with AS_ECHO where this wasn't necessary.
6279 Problem reportd by Ralf Wildenhues.
6280 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
6281 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
6282 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
6284 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6286 * lib/freeze.mk (GREP): Removed, no need to initialize this.
6288 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
6290 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
6291 that traditional Awk lacks 3-arg "split". It has it.
6292 Mention that FS must be a single character, and a few other
6293 99-byte limits of traditional Awk.
6294 Mention that if (i in a) doesn't work with traditional Awk.
6296 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
6298 * tests/autotest.at (BSx641-newline in command):

6300 (Newline-CODE-BS-newline in command):
6301 (Single-quote-BS-newline in command):
6302 (Single-quote-newline-BS-newline in command):
6303 Use printf '%s\n' instead of echo, for portability to hosts
6304 where echo interprets backslashes. This will break on hosts
6305 that lack printf, but for now let's assume all such hosts
6306 are dead (if not, we should get reports of test failures).
6308 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
6310 'echo' has some portability problems, when given a first argument
6311 with a leading '-', or when given any argument containing '\'.
6312 Avoid using 'echo' in these cases.

6344 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
6345 rather than using a here-document to put the script into a file.

6349 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
6350 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
6351 bug, but we might as well stop using ECHO_N and ECHO_C internally.

6356 operand, as AS_ECHO requires. Avoid double file name expansion.
6357 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
6358 Don't set as_nl, since _AS_ECHO_PREPARE does that now.

6360 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.

6362 Double-quote strings that would otherwise contain M4 comments.
6363 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
6365 * configure.ac (AC_INIT): Bump to 2.61a.
6368 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
6372 * configure.ac (AC_INIT): Bump to 2.61.
6375 * tests/autotest.at (Macro with backslash in a test title):
6376 Comment out for now, as this tests neither fails nor passes
6377 reliably. Problem reported by Ralf Wildenhues.
6379 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
6381 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

6456 benefit of platforms like Solaris+GCC where it is common to have a
6457 non-working g++ installation.

6461 and Paul Eggert <eggert@cs.ucla.edu>
6463 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
6464 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
6467 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
6469 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
6470 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
6471 Imported from a similar patch to gnulib by Bruno Haible.
6473 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
6475 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

6492 and Stepan Kasal <kasal@ucw.cz>
6494 Handle special characters in test case titles correctly.

6497 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
6498 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
6499 argument. Extend to check titles printed by ./micro-suite and

6502 Single-quote in a test title,
6503 Double-quote in a test title): Don't expect failure anymore.
6504 (Backslash in a test title): Put a non-whitespace character after the
6505 backslash so that Bourne shells might actually see it as an escape
6507 (Brackets in a test title,
6508 Pound in a test title,
6509 Comma in a test title,
6510 Quoted Macro in a test title,
6511 Macro in a test title,

6513 (Macro with backquote in a test title,
6514 Macro with double-quote in a test title,
6515 Macro with backslash in a test title): New tests expected to fail.
6516 * tests/torture.at (#define header templates): M4-quote this title in
6517 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
6518 The visible effect was a stray [] in the testsuite output.
6520 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6522 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
6523 `trap ... 0' inside a function, for AIX sh.
6525 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
6527 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
6528 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
6529 5363) simply issues a warning when dividing by zero at compile
6530 time. Problem reported by Elias Pipping.
6532 2006-10-26 Eric Blake <ebb9@byu.net>
6535 * doc/autoconf.texi (Evaluation Macros): Improve the example to
6536 show effect on macros that expand with commas.

6561 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
6563 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
6564 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
6565 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
6566 reported by Nelson H. F. Beebe for Coreutils 6.4.
6568 * tests/tools.at (autoconf --trace: user macros): Remove test
6569 for tracing multiline macros, since m4 1.4.7a uses a different
6570 way to number lines. Problem reported by Ralf Wildenhues.

6596 * NEWS: Remove AC_CACHE_CHECK_INT.
6597 * doc/autoconf.texi (Caching Results): Likewise.
6598 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
6599 AC_CACHE_CHECK_INT, since it's no longer public.
6600 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
6601 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

6631 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
6632 looking for special shell characters.
6633 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
6634 macro defined by AS_VAR_PUSHDEF before passing it as a

6646 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
6648 (Imported from Automake.)
6649 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
6650 which incorrectly sets the mode of an existing destination
6651 directory. In some cases the unpatched install-sh could do the
6652 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
6653 system. We hope this is rare in practice, but it's clearly worth
6654 fixing. Problem reported by Alex Unleashed in
6655 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
6656 Also, don't bother to check for -m bugs unless we're using -m;
6657 suggested by Stepan Kasal.
6659 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
6661 Import this change from Automake:
6663 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
6664 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
6665 is enabled by default with gnu and gnits strictness.
6666 Report from Bruno Haible.
6668 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

6670 gnu and gnits modes.
6672 Import this change from Config:

6677 Import this change from Gnulib:
6679 2006-09-16 Karl Berry <karl@gnu.org>

6690 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
6691 (\code): must use new \...Char values, since now ` is active.
6693 2006-08-26 Karl Berry <karl@gnu.org>
6694 * build-aux/texinfo.tex (\textdegree): New command.
6696 2006-08-12 Karl Berry <karl@gnu.org>

6701 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
6703 2006-10-13 Stepan Kasal <kasal@ucw.cz>
6705 * doc/autoconf.texi (Autoheader Macros): Warn that the text
6706 added to the template can get mangled.
6708 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6710 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
6711 include the default headers, and redefine obstack_chunk_alloc
6712 and obstack_chunk_free. Fixes false failure with glibc.
6714 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
6716 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

6731 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
6733 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
6734 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
6735 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
6736 Use a better substitute, by inspecting the output of "ls"
6737 rather than just using ":".
6738 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
6739 rather than AS_EXECUTABLE_P, since we needn't worry about
6740 non-regular files here.
6742 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
6743 due to configuration hassles with this. See Tonya Underwood's report
6744 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

6751 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
6753 2006-10-11 Stepan Kasal <kasal@ucw.cz>
6755 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
6756 initialization which is not inherited through the environment
6757 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
6758 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

6763 problems with mkdir -p -m.
6765 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
6767 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
6768 comment about ac_cpp_err; it was incorrect, and anyway
6769 ac_cpp_err is being removed below.
6770 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
6771 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
6772 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
6774 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
6775 with werror_flag and conftest.err and so forth. This is more
6776 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
6777 and anyway the user shouldn't normally want to see this gorp logged.
6778 Problem reported by Ralf Wildenhues.
6779 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
6780 empty, not 'no', since the rest of the code uses 'test -z'.
6782 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
6784 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
6785 Use a single call to AC_DO_TOKENS rather than multiple, for
6787 (_AC_LINK_IFELSE): Test that resulting file is executable.
6788 Problem reported by mwoehlke in
6789 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
6791 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
6792 than creating a file to use with test -x; this is much faster.
6794 2006-10-02 Bruno Haible <bruno@clisp.org>
6796 * lib/autom4te.in (Automake-preselections): Add
6797 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
6799 2006-09-27 Stepan Kasal <kasal@ucw.cz>
6801 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
6802 standard error, `experr' should be used, not `expout'.
6804 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
6806 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
6807 fseeko testing program twice; just use the earlier result.
6808 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
6809 Set cache var to 'unknown' (not 'no') if leaving the macro unset
6810 still doesn't let the program compile.
6811 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
6814 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
6815 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
6816 include it, without including anything else.
6817 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
6819 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
6821 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6823 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
6824 `error.h', and include it, for a `error_at_line' prototype.
6825 Use a nonempty format string in the link test.
6826 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
6827 for a declaration of wait3.

7285 more globally, since the 2006-06-30 patch didn't suffice. Problem
7286 reported by Keith Marshall. Also, don't bother with builddir2,
7287 since it shouldn't be needed any more.
7289 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
7291 * doc/autoconf.texi (Generic compiler characteristics):
7292 Document AC_COMPUTE_INT. Fix wrong statements on Default
7293 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
7295 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
7296 (_AC_COMPUTE_INT): Add obsoletion warnings.
7297 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
7300 * NEWS: Document change.
7302 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
7304 * doc/autoconf.texi (Volatile Objects): New section.
7306 * NEWS: Document previous change.
7308 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
7310 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
7311 Require that long long int be at least 64 bits wide. C99 requires
7312 this and enough programs depend on it so we should check for it.
7313 Bruno Haible reports in
7314 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
7315 that long long int is 32 bits wide with some nonstandard compilers.
7316 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
7318 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
7320 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
7321 to a nonexistent file, so that we don't have to worry about
7322 a local site configuration that doesn't use /usr/local.
7323 Problem reported by Keith Marshall in
7324 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
7326 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
7328 * doc/autoconf.texi: Be more consistent about using @acronym with
7329 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
7330 quite right (it talked about "OSF/Tru64", even though the
7331 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
7332 and it even mentioned "OSF 4"!) and at this point there's little
7333 reason to talk about OSF any more, since it died in 1994.
7334 (Specific Compiler Characteristics): Simplify example of
7335 negative-size array.
7336 (File Descriptors): Reorder to make the text flow better.
7337 Remove joke about "appreciate the various levels"; I didn't get it.
7338 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
7339 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
7340 (File Descriptors, Limitations of Usual Tools):
7341 Tone down the advice against renaming or removing open files.
7342 (Limitations of Usual Tools): Add a new section, on 'rm'.
7344 2006-06-26 Stepan Kasal <kasal@ucw.cz>
7346 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
7347 -lXt in LIBS, idea from Karsten Hopp; this was due since
7350 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7351 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7352 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7353 (which belong to Xt, not X itself). See Debian bug 327655.
7355 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7357 * configure.ac (AC_INIT): Bump to 2.60a.
7360 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7364 * configure.ac, NEWS: Update.
7366 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7368 * config/texinfo.tex: Sync from upstream.
7370 * bin/autom4te.in (handle_traces): Transform the `@S|@'
7371 quadrigraph correctly in traces.
7373 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
7376 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
7377 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
7379 * doc/autoconf.texi (Changed Directory Variables): New node,
7380 to document the whole `datarootdir' business a bit better.
7382 * tests/torture.at (datarootdir workaround): Extend test.
7383 Prompted by report by Alexandre Julliard.
7385 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
7387 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
7388 when using default mode of IBM C 6 for AIX. Problem and two-line
7389 fix reported by Larry Jones.
7391 2006-06-22 Alexandre Julliard <julliard@winehq.org>
7393 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
7394 about literal '${datarootdir}' if a definition is found in the
7397 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
7399 * NEWS: Use "M4" rather than "m4" when appropriate.
7400 Problem reported by Eric Blake.
7401 * doc/autoconf.texi: Likewise.
7402 Use @acronym around BSD, GCC, and GNU when appropriate.
7403 (Why GNU M4): Renamed from "Why GNU m4".
7404 (Redefined M4 Macros): Mention that Posix
7405 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
7406 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
7409 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7411 * bin/autom4te.in (handle_output): Do not forbid the empty
7413 * tests/tools.at (autoconf: the empty token): New test.
7415 2006-06-20 Stepan Kasal <kasal@ucw.cz>
7417 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
7418 calls, so that we do not care whether they are LIFO or FIFO;
7419 in the m4_wrap, do not check which diversion is the topmost
7420 one, just check that the stack is balanced at the end.
7421 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
7422 base diversion forever--pop the previous diversion before
7423 opening the new one; consequently, remove the m4_wrap call.
7424 * lib/autotest/general.m4 (AT_INIT): Likewise.
7425 * tests/m4sugar.at: Do not use
7426 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
7428 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
7429 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7431 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
7432 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
7433 Rework example of m4wrap token-pasting trouble so that it doesn't
7434 care whether it's LIFO or FIFO.
7435 Fix some "contrary to"s that are awkward in English.
7437 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7439 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
7440 to `yes' instead of `int$1_t' if the type is found, for more
7441 consistent configure output (where $1 is the number of bits).
7442 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
7443 Suggested by Bruno Haible.
7445 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
7446 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
7447 with system headers. Report by Bruno Haible.
7449 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7451 * config/config.guess, config/config.sub: Sync from upstream.
7453 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
7454 in order to avoid picking up an older installed frozen m4sh.m4f.
7455 Besides an outdated shell startup, this could have been created
7456 by an earlier M4 version with incompatible frozen file format.
7458 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
7460 * README: Recommend m4 1.4.4 instead of 1.4.3..
7461 * doc/autoconf.texi: Likewise.
7462 (Special Chars in Names): Say that $(.FOO) is portable, as
7463 suggested by Stepan Kasal.
7464 (Installation Directory Variables, Build Directories):
7465 (Automatic Remaking, Subdirectories, Fortran Compiler):
7466 (Making testsuite Scripts, Defining Directories):
7467 Quote variable usages better.
7468 (Making testsuite Scripts): Add clean-local rule to makefile
7469 snippet, by Eric Blake.
7470 (Installation Directory Variables): Fix table item font.
7471 Reword slightly to clarify. Generalize advice about
7472 not using special characters to include all file-related
7473 vars, not just VPATH.
7474 (Special Chars in Variables): Warn about special characters in
7476 (Assignments): Clarify default-value example as suggested by
7478 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
7479 (Special Shell Variables): Note leading ./ or ../, as suggested
7481 (Limitations of Builtins): Under cd, warn about CDPATH.
7482 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
7485 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7487 * doc/autoconf.texi (Configuration Actions): Remove duplicate
7488 `@var', for texi2html.
7489 (Systemology): Some more word wrapping, for DVI output.
7490 (autom4te Invocation): The short option for `--melt' is `-M',
7493 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
7495 * doc/autoconf.texi: More formatting and English tweaks,
7496 many suggested by Ralf Wildenhues.
7497 Reword to avoid "@code{...}'s" and the like, since it's ugly
7498 with Emacs info mode. discontents -> woes.
7499 Put a few "will"s back. time stamp -> timestamp.
7500 side-effect -> side effect.
7502 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
7504 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
7505 Warn about $@ not persisting. Problem reported by Julien Danjou in
7506 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
7507 (Special Chars in Names): Renamed from Leading _ in Macro Names.
7508 Mention other special chars, too.
7510 2006-06-14 Eric Blake <ebb9@byu.net>
7512 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
7514 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
7516 * doc/autoconf.texi: Some systematic minor improvements, as
7517 follows. Use "makefile" when talking about makefiles
7518 generally (which might be named "makefile" or "Makefile" or even
7519 "foo.mk"), "Makefile" when talking about a specific makefile
7520 called "Makefile". This unclutters the text from weird quotes
7521 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
7522 values" rather than "@var{foo}s" and similar constructs containing
7523 "}s". Use "Make rules" rather than "Makefile rules". Minor
7524 English-language improvements. Change the prefix "sub-" to "sub"
7526 Put blank lines around examples more consistently.
7527 Avoid "rather" and "very" as intensifiers.
7528 Avoid "will" as an auxiliary.
7529 (Limitations of Make): Split this node into....
7530 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
7531 (Leading _ in Macro Names, Backslash-Newline-Newline):
7532 (Backslash-Newline Comments, Long Lines in Makefiles):
7533 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
7534 (obj/ and Make, make -k Status, VPATH and Make):
7535 (VPATH and Double-colon, $< in Explicit Rules):
7536 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
7537 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
7538 New nodes, resulting from splitup of Limitations of Make.
7539 All cross-references changed. Raise the top node from
7540 a section to a chapter, and all subnodes accordingly.
7541 Redo the introductory wording to match the new organization.
7542 (Installation Directory Variables): Use an example that is
7543 closer to what Autoconf actually does. Mention that VPATH's
7544 value should not contain metacharacters or white space.
7545 (Fortran Compiler): Fix a VPATH bug in an example.
7546 (Leading _ in Macro Names): Mention that this problem is no longer
7547 of practical concern.
7548 (VPATH and Make): Reword the advice to make it clearer
7549 that Autoconf and Automake support VPATH in non-GNU make, but
7550 many packages have bugs in this area.
7551 ($< in Explicit Rules): Refer to Build Directories rather
7552 than using a (non-VPATH-safe) example.
7553 (Automatic Rule Rewriting): Mention the sort of disaster that
7554 can ensue with Solaris-style rule rewriting with VPATH.
7556 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7558 * doc/install.texi (Compilers and Options): Weaken the
7559 suggestion to use GNU make for VPATH builds.
7561 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
7562 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
7564 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
7565 in regular expression.
7567 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7569 * doc/autoconf.texi (Installation Directory Variables):
7570 Drop extra @samp from `@table @samp' item.
7571 (Limitations of Usual Tools): Comment fix.
7572 Do not nest @samp just to point to other table items.
7573 (Writing testsuite.at) <AT_CHECK>: The second argument to
7574 `@dvar' is already @samp'ed.
7575 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
7576 do not use @var in the second argument.
7578 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
7580 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
7581 $as_shell.exe too. Problem reported by Andreas Buening in
7582 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
7584 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7586 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
7587 `unused variable' compiler warning, for `-Wall -Werror'.
7588 Reported by Jaap Haitsma in
7589 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
7591 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
7593 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
7594 case the compiler dumps core. Problem reported for
7595 OpenServer 5.0.7 by Tim Rice in
7596 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
7597 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
7600 2006-06-06 Tim Rice <tim@multitalents.net>.
7602 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
7603 "ERROR" only shows up in "make check" output if there is an
7606 2006-06-06 Eric Blake <ebb9@byu.net>
7608 * tests/tools.at (automatically allowed tokens): Fix typo.
7610 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7612 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
7614 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
7615 typically overflows on x86 CPUs, even though the C standard
7618 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7620 * configure.ac (AC_INIT): Bump to 2.59e.
7623 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7627 * config/texinfo.tex: Sync from upstream.
7629 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
7630 seen, invoke libtoolize with `--ltdl' argument.
7631 * lib/autom4te.in (Autoreconf-preselections): Adjust.
7633 Suggested by Eric Blake.
7635 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7637 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
7638 reported by Ralf Wildenhues.

7651 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
7652 message issued by AC_REQUIRE.
7653 * tests/m4sugar.at: Check m4_require's error message.
7654 * tests/base.at: Check AC_REQUIRE's error message.
7655 * tests/local.at (AT_CHECK_M4): New macro, almost identical
7657 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
7659 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
7660 `expout' as the last parameter.
7661 * tests/tools.at: Adapt to the above change.
7663 2006-06-04 Stepan Kasal <kasal@ucw.cz>
7665 * doc/autoconf.texi (Limitations of Usual Tools): Correct
7666 information about race-free implementations of mkdir.

7675 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
7677 * NEWS: GNU make now recommended for VPATH builds.
7678 Mention that some macros are now documented to be obsolescent.
7679 * doc/autoconf.texi:
7680 Prefer "current" to "modern" to describe
7681 currently-used (albeit perhaps old-fashioned) hosts.
7682 Mention which ancient features no longer need to be worried about.
7683 setgid -> set-group-ID
7684 setuid -> set-user-ID (these are the Posix terms)
7685 Fix some misuses of "only".
7686 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):

7697 (File Descriptors): Mention that 0, 1, 2 might get reopened.
7698 Mention that it's now safe to use 3 and 4.
7699 (Limitations of Usual Tools): cp -r is now specified by Posix.
7700 Omit longwinded and obsolescent discussion of cp -f.
7701 Modernize discussion of expr, ls.
7702 (Limitations of Make): Modernize discussion of VPATH builds.
7703 Mention $? as a workaround in some cases.
7704 * doc/install.texi (Basic Installation):
7705 Mention "./configure; make; make install" first. Be more
7706 specific about why this file is generic. Remove unnecessary
7707 parens. Remove misleading "only". Remove obsolete advice
7708 about csh. Don't say "configure" takes awhile; say it
7709 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
7710 and CC=c99 rather than CC=c89, as these are blessed by current
7711 Posix. Recommend GNU make if doing a VPATH build.
7713 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
7715 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
7716 examples involving shell prompts.

7732 anywhere in directory names.
7734 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
7736 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
7737 about quoting the case statement, just in case.

7753 argument with leading hyphen. Problem reported by Paul Eggert.
7755 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7757 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
7758 about quoting ac_try: quote all of it, if any of it seems suspicious.
7759 This means we don't have to worry about ${ or sed any more.
7760 Also, double-quote the case statement, to work around misuses via
7761 underquoting as reported by Ralf Wildenhues in
7762 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
7763 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
7764 undocumented and dangerous macro.
7765 Problem reported by Ralf Wildenhues in
7766 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
7768 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7770 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
7771 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
7772 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
7774 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7776 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
7777 since evidently some packages rely on the old, broken behavior.
7778 Problem reported by Ralf Wildenhues in
7779 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
7780 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
7781 pre-2006-05-26 definitions, but leave in the comments that
7782 these macros are dangerous and should not be used.
7783 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
7784 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
7785 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
7786 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
7787 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
7789 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
7791 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
7792 the use of 'tr', since this is our only use of 'tr'.
7794 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7795 and Paul Eggert <eggert@cs.ucla.edu>
7797 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
7798 Don't assume 'grep' works on long lines, since AIX grep doesn't.
7800 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7802 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
7803 the output file in the `${datarootdir}' test.
7805 2005-05-28 Stepan Kasal <kasal@ucw.cz>
7806 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7808 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
7809 mention of `datarootdir' in the input file(s), but literal
7810 `${datarootdir}' in the output file, and we haven't warned yet,
7811 then warn as well: the user may have (erroneously) used
7812 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
7813 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
7814 * tests/torture.at (datarootdir workaround): Extend this test.
7817 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7818 and Paul Eggert <eggert@cs.ucla.edu>
7820 * doc/autoconf.texi (autoheader Invocation): The first argument to
7821 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
7822 alternatives and clear up the language a bit.
7824 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
7826 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
7827 ac_config_guess, ac_config_sub, ac_configure.
7828 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7829 Fix typo that prevented an unnecessary space from being removed.
7830 Problems reported by Ralf Wildenhues in:
7831 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
7833 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
7835 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
7836 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
7837 Don't use the term "thread-safe" to talk about mkdir race
7838 conditions, since the problem is more a process than a thread
7839 issue. Problem reported by Stepan Kasal in:
7840 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
7841 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
7842 the test for 'install' more closely. Look at MKDIR_P first.
7843 Look in the PATH, and at /opt/sfw/bin.
7844 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
7845 Don't bother to try mkdir -p, since we already check mkdir --version;
7846 just look at the version number. (There's no easy way to check
7847 for race-free implementations.)
7848 * tests/tools.at (autoconf: subdirectories): Adjust to above
7849 changes, since MKDIR_P now might end in "/mkdir -p".
7851 * doc/autoconf.texi (autoheader Invocation): Mention that the
7852 first arg of AC_DEFINE_UNQUOTED must be a literal.
7853 Problem reported by Ben Pfaff in
7854 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
7856 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
7857 * doc/autoconf.texi (Special Chars in Variables): New section.
7858 (Preset Output Variables): Warn about special chars in CPPFLAGS.
7859 (Installation Directory Variables): Quote $(datadir) better.
7860 (Limitations of Builtins): Describe some of eval's trickiness.
7862 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
7863 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
7864 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
7865 in front of every arg, not just trailing args. Quote apostrophes.
7866 (_AC_EVAL_ECHO): New macro.
7867 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
7868 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
7870 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
7871 exposed by quoting of eval argument. Put the command on line line
7873 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
7874 (_AC_PATH_X, AC_PATH_X): Quote more safely.
7875 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
7876 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
7877 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
7878 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
7879 Use eval more safely.
7880 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
7881 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
7883 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
7884 lines, exposed by quoting of eval argument.
7886 2006-05-26 Stepan Kasal <kasal@ucw.cz>
7887 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7889 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
7890 initialization of `ac_cv_exeext', do not override it if it was
7891 already set, unless it was set to `no', for compatibility with
7892 Autoconf-2.13, and comment this.
7893 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
7894 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
7895 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
7896 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
7897 Document that this test may be overridden by setting
7900 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7902 Revert these two patches:
7904 2006-04-06 Eric Blake <ebb9@byu.net>
7905 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
7906 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
7909 2006-04-01 Stepan Kasal <kasal@ucw.cz>
7910 Clean up _AC_COMPILER_EXEEXT* macros.
7911 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
7912 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
7913 ac_file to the name of the default output file and call
7914 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
7915 initial `rm' of the candidate files...
7916 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
7917 the same list in subsequent `rm' calls, and for the temporary
7918 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
7919 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
7920 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
7921 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
7922 no longer needed) by libtool. Make it a cache check.
7923 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
7924 copied here by mistake.
7925 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
7926 _AC_COMPILER_EXEEXT.
7927 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
7928 _AC_COMPILER_OBJEXT directly.
7929 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7931 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7933 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
7934 Fix description of how the buggy `sed' works.
7936 2006-05-25 Noah Misch <noah@cs.caltech.edu>
7940 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
7941 ENOLCK. Only mention `make -j' when applicable. Only raise
7942 fatal errors when `make -j' is involved. Improve error message.
7944 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7946 * doc/autoconf.texi (Here-Documents): We now know more about
7947 the variable expansion in here documents bug.
7948 Thanks to Tim Rice and Stepan Kasal.
7950 * doc/autoconf.texi (Making testsuite Scripts): Add an example
7951 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
7953 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7955 * tests/autotest.at (Multiline command from M4 expansion):
7956 No failure to be expected if the shell quotes newlines in
7957 commands in the `set -x' output. Report by Tim Rice.
7960 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
7962 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
7963 expansion in the here-documents used by config.status, as that
7964 runs afoul of the Korn shell version M-12/28/93d bug described in
7965 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
7966 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
7967 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
7969 2006-05-23 Jim Meyering <jim@meyering.net>
7971 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
7972 Fix typo introduced with 2006-04-02 change. It reversed the sense
7975 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
7977 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
7978 ac_dB slightly, to save bytes in the script.
7979 Max out at 50 lines, rather than 96; this is more likely
7980 (though not guaranteed) to avoid obscure 'sed' failures.
7982 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7984 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
7985 `tr -d -' as bad option argument. Work around this by deleting
7986 an unrelated character.
7987 Report by Tim Rice <tim@multitalents.net>.
7989 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
7990 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7991 Stepan Kasal <kasal@ucw.cz>
7993 * doc/autoconf.texi (Particular Programs): Do not promise that
7994 we always prefer the GNU version of the program, and that we
7995 search according to PATH; both rules can have exceptions.
7996 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
7997 AC_PROG_SED. Move descriptions of limitations
7998 to the Limitations of Usual Tools section.
7999 (Limitations of Usual Tools) <sed>: Mention script length
8000 limitations with Solaris /usr/ucb/sed.
8001 <grep>: Fix wording for empty alternative. Mention that -c and
8002 -l should not be combined, and that -E and -F should not be
8005 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8006 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8008 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
8009 limits in Solaris 8 /usr/ucb/sed by testing a long script.
8011 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8013 * doc/autoconf.texi (Defining Symbols): Literal parameter of
8014 AC_DEFINE is now passed to m4_pattern_allow.
8015 * NEWS: Mention that; likewise for AC_SUBST.
8016 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
8017 the parameter to m4_pattern_allow.
8018 * tests/tools.at: Add a check for that.
8020 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8022 * lib/autoconf/status.m4: Fix typos.
8024 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8026 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
8027 only the files that this macro generates.
8029 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8031 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
8032 the HP-UX sed limitation of 99 commands, labels do not count.
8033 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
8035 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
8037 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8039 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8040 Import the following fix from coreutils:
8042 2006-01-13 Jim Meyering <jim@meyering.net>
8044 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
8045 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
8046 not double-quote uses of that variable, to accommodate the rare
8047 case in which getmntent is available in none of the libraries
8048 checked. This happens at least on FreeBSD 5.0.
8050 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
8052 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
8053 ac_config_guess, ac_config_sub, and ac_configure, since evidently
8054 some other programs unwisely rely on these undocumented vars.
8055 But put in warning comments about them.
8056 Problem reported by Ralf Wildenhues in
8057 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
8058 * NEWS: Document that these variables are intended to go away.
8060 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8062 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
8063 and set the language to C++ (analogous to the equivalent Fortran
8066 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
8067 * doc/autoconf.texi (C++ Compiler): Document it.
8068 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
8071 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
8073 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
8074 that caused config.status to generate 100-command sed scripts; the
8075 portable limit is 99.
8077 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8079 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
8080 variable `ac_d' instead of `d' to avoid infringing namespace.
8081 Report by Ralf Menzel.
8083 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
8085 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
8086 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
8087 * tests/tools.at (autoconf: subdirectories): New test, taken from
8088 the corresponding problem report by Ralf Wildenhues in:
8089 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
8091 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
8092 Quote some uses of shell variables if they might suffer unexpected
8093 globbing. This doesn't fix all instances of quoting problems that
8094 I found, just the easy ones that look safe.
8095 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
8096 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
8097 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
8098 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
8099 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
8100 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
8101 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
8103 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
8104 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
8106 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8108 * bin/autoreconf.in ($help): Reword according to the manual.
8109 Suggested by Olly Betts.
8111 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
8112 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8114 * bin/autoreconf.in: Pass the directory argument to
8115 `require_configure_ac'. Fix comment.
8116 * tests/torture.at (Configuring subdirectories): Expose this.
8117 Reported by Olly Betts.
8119 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8121 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
8122 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
8123 Automake as follows:
8125 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
8126 `$configure_in' instead of `configure.in', to preserve
8127 directory component.
8129 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8131 * config/config.guess, config/config.sub, config/texinfo.tex,
8132 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
8134 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
8136 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
8137 test for C99 conformance; (bool) 0.5 is an integer constant
8138 expression, but (bool) -0.5 is not. Problem reported by Fedor
8139 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
8141 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
8143 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
8144 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
8145 Warn about obsolete install-sh files. Remove stray sentence
8146 fragment and fix cross reference.
8147 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
8148 install -d; this undoes the 2006-05-10 change.
8149 (MKDIR_P): Mark with AN_MAKEVAR.
8150 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
8151 that we don't require $INSTALL to be thread-safe. Move comments
8152 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
8153 of AC_PROG_INSTALL. Output a message saying that we're checking
8154 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
8155 MKDIR_P instead of AC_SUBST.
8156 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
8157 Special magic for MKDIR_P, too.
8158 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
8160 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
8162 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
8164 Sync from Automake, as follows:
8166 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8167 * config/install-sh: Initialize IFS, so field splitting isn't
8169 * config/mkinstalldirs: Likewise.
8170 * config/missing: Remove superfluous quotes. Replace all uses of
8171 `[' by `test', for consistency, and for..
8172 * config/missing (sed_minuso, sed_output): New variables.
8173 (autom4te, help2man, makeinfo): Use them. Unifies detection of
8174 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
8175 Fixes `missing' to detect `--output' for help2man. Fixes
8176 PR automake/483. Report by Dennis J. Linse.
8177 (autom4te): Document in `missing --help'.
8179 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8181 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
8182 * config/install-sh: Don't use 'path' to talk about file names,
8183 as per GNU coding standards. Close a race condition reported by Ralf
8184 Wildenhues and Stepan Kasal. There is still a race condition
8185 on hosts that predate Posix 1003.1-1992, but we can't help this.
8186 Don't mishandle weird characters like space on pre-Posix hosts.
8187 Invoke mkdir at most once per dir arg on pre-Posix hosts.
8188 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
8189 AC_PROG_MKDIR_P from AS_MKDIR_P.
8190 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
8191 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
8192 earlier editions are not (including Automake 1.8.3).
8193 Do not suggest mkinstalldirs for thread-safety.
8194 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
8195 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
8196 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
8197 presence of special characters and race conditions.
8198 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
8199 in Autoconf's name space.
8201 2006-05-10 Bruno Haible <bruno@clisp.org>
8202 and Paul Eggert <eggert@cs.ucla.edu>
8204 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
8205 from Automake with minor changes.
8206 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
8208 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8210 * config/install-sh: Update to Automake CVS version, as follows:
8211 2006-04-25 Stepan Kasal <kasal@ucw.cz>
8212 * lib/install-sh: Simplify the expr implementation of dirname.
8213 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
8214 * lib/install-sh: Handle --, and diagnose unknown options.
8216 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8218 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
8219 `./autom4te' to create `./testsuite', since the `all' target
8220 will ensure its presence, but `installcheck' should not create
8221 the uninstalled wrappers.
8223 * tests/torture.at (Unusual Automake input files): Skip if we
8224 detect automake < 1.8.
8226 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8228 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
8229 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
8230 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
8233 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8235 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
8236 munge (multiple) white space and other oddities.
8237 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
8238 single quotes in variable assignment.
8239 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
8240 and similar failures by adding multiple spaces, tabs, and other
8242 Report and different test suggested by Francesco Romani
8243 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
8245 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
8246 single quotes, we only need to search for single quotes; this
8247 both simplifies the search pattern, and makes us less
8248 susceptible to `echo' variations for arguments not containing
8250 (_AC_ARG_VAR_VALIDATE): Likewise.
8252 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8254 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
8255 `$*' and IFS concatenation issue with traditional shells and
8256 bash-2.04. Report by Seanster@Seanster.com.
8258 2006-05-03 Bruno Haible <bruno@clisp.org>
8260 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
8261 precisely which Mac OS X versions have the od problem.
8263 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
8265 * doc/autoconf.texi: Use @option systematically.
8267 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
8268 and Bruno Haible <bruno@clisp.org>
8270 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
8272 (Integer Overflow): Mention the special case of integer division
8275 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8277 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
8278 traditional shells like the Solaris one that do not use the
8279 first IFS character for assembling `$*'.
8280 Prompted by a related report from autoconf_bug@nro.ca.
8282 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
8283 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8285 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
8286 Mention more problems with the -e option.

8291 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
8293 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
8294 in URLs to improve DVI formatted output (requires texinfo 4.6).

8302 `action-if-found' -> `action-if-true' and similarly.
8303 (Obsolete Macros): Likewise.
8304 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
8305 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
8306 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
8308 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8310 * doc/autoconf.texi (Limitations of Make): Clean up markup.
8313 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
8316 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8318 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
8319 /bin/sh set unsorted output.

8326 (Integer Overflow, Null Pointers, Buffer Overruns):
8327 (Floating Point Portability, Exiting Portably): New sections.
8328 (Writing Test Programs): Fix some langauge. Recommend exiting
8329 with status 1, not merely nonzero. Clarify exit declaration.
8330 (Run Time): Move C exit status stuff to new Exiting Portably section.
8331 (Systemology): Mention Posix and levenez. Update v7 reference.
8332 (Portable Shell): Mention the Posix shell.
8334 2006-04-25 Stepan Kasal <kasal@ucw.cz>
8336 * bin/autoconf.as (me): Replace by as_me.
8338 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
8340 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
8341 since as_me isn't set yet.
8343 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
8345 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
8346 a few minor bugs in this area.
8348 * doc/autoconf.texi (Programming in M4sh): Comment out the
8349 documentation of AS_BASENAME, for now.
8350 (Shell Substitutions): Do not use AS_DIRNAME in an example.
8351 (Limitations of Builtins) <basename>: Do not refer to
8353 * bin/autoconf.as (me): Don't use AS_BASENAME.
8354 (dir): Remove the unused variable.
8355 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
8356 AS_DETECT_REQUIRED. All uses changed.
8357 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.

8362 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
8363 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
8364 (_AS_DIRNAME_PREPARE): Likewise.
8365 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
8366 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
8367 (AS_DIRNAME): Use "dirname --".
8369 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
8371 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
8372 of "run time" and "run-time" changed to "runtime", for consistency.
8373 * lib/autoconf/fortran.m4: Likewise (in comment).
8374 * lib/autoconf/functions.m4: Likewise.
8375 * lib/autoconf/general.m4: Likewise.
8376 * lib/autoconf/headers.m4: Likewise.
8378 * doc/autoconf.texi (Run Time): Document the exit status situation
8379 with more accuracy and detail.
8381 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8383 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
8384 Archive is not officially `GNU' any more. Update URL.
8385 (Defining Directories): Likewise
8386 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
8388 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8390 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
8391 newline from the `trap' code to finish `config.log'; the NetBSD
8392 /bin/sh resets the exit status after an empty command, as
8393 documented in doc/autoconf.texi.
8394 Reported by Dalibor Topic <robilad@kaffe.org>.
8396 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
8398 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
8399 Suggested by Bruno Haible.
8401 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
8403 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
8404 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
8405 Instead, just list the shells that we know work.
8406 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
8407 changed. Be more cautious about the _cv_ variable.
8408 * tests/tools.at (Syntax of the shell scripts): Check the
8409 _cv_ variable once, at first, to avoid an internal autoconf error
8410 when sh -n does not work.
8412 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8414 * lib/Autom4te/FileUtils.pm: Sync from Automake.
8416 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
8418 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
8419 use ">&-" since we're only 99.999% sure that this is portable,
8420 and since the MinGW bug is fixed in a different way.
8421 * lib/autotest/general.m4 (AT_INIT): Likewise.
8423 2006-04-16 Stepan Kasal <kasal@ucw.cz>
8425 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
8426 before opening config.log, to avoid hitting a bug on MinGW.
8428 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
8430 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
8431 AS_MESSAGE_LOG_FD before reopening it onto the log file.
8432 This works around a MinGW bug reported by Eric Paire.
8433 Make sure that all writes to the log file append to it,
8434 rather than possibly losing data.
8435 * lib/autotest/general.m4 (AT_INIT): Likewise.
8437 2006-04-14 Stepan Kasal <kasal@ucw.cz>
8439 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
8442 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8446 * configure.ac (AC_INIT): Bump to 2.59d.
8448 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8452 * Makefile.maint (news-date-check): Do not require a leading `*'
8453 before the release date in NEWS.
8455 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8456 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8458 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
8459 the instantiated file do not contain the string 'datarootdir'
8460 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
8461 @mandir@, replace the reference '${datarootdir}' by the value.
8462 * tests/torture.at (datarootdir workaround): New test.
8463 * NEWS: Advertise this temporary fixup.
8464 Based on a patch by Bruno Haible, reported and analyzed by
8465 Paul Eggert and Noah Misch.
8467 2006-04-12 Eric Blake <ebb9@byu.net>
8469 * tests/autotest.at (Debugging a failed test): Fix comment.
8471 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8473 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
8474 all the changes since 2006-04-07.
8476 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8478 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
8479 succeeded, but `ln -s file dir' failed, take care to remove the
8480 leftover target before the next test, to prevent its spurious
8481 failure; also make sure `ln file dir' works before selecting it.
8482 Thanks to Keith Marshall for pointing this out.
8485 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
8486 assignments in `at_debug_args', so that we put them correctly
8487 in the `run' script.
8488 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
8489 Reported by Eric Blake.
8491 2006-04-11 Eric Blake <ebb9@byu.net>
8493 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
8494 top-level tests after micro-suite has been run. Used in...
8495 (Debugging a successful test, Debugging script and environment),
8496 (Debugging a failed test): ...these new tests. The first of these
8498 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
8499 macro, split out from...
8500 (AT_INIT): ...here, so that using -d also generates a run script.
8501 Document that -d inhibits top-level logging.
8502 * doc/autoconf.texi (testsuite Invocation): Document that -d only
8503 inhibits top-level logging; debug scripts are created.
8505 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
8507 * tests/autotest.at (Empty test, Empty check): New test to check it.
8509 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
8512 2006-04-10 Stepan Kasal <kasal@ucw.cz>
8514 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
8515 the files if a problem appears. Make the empty *.at files
8516 read-only, too. Proposed by Ralf Wildenhues.
8518 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8520 * config/Makefile.am: Add comment to force updated Makefile.in.
8522 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
8523 space only patch to this file, this patch causes the Makefile.in
8524 files that include freeze.mk to be updated, and thus have a
8525 newer time stamp again, which in turn makes a pristine CVS
8526 checkout have correct time stamps.
8528 * Makefile.maint (cvs-sv): New macro, to be used..
8529 (config.guess-url_prefix, config.sub-url_prefix)
8530 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
8531 point to CVS text checkout of Gnulib files.
8532 (copyright-check): Bump current year.
8533 (announcement): Do not hard-wire `./announce-gen'.
8534 (cvs-update): Propagate failures of `cvs' and `move-if-change'
8536 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
8538 (wget_files): Update config.guess, config.sub, texinfo.tex by
8539 `wget-update', now that their URLs work again.
8541 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
8543 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
8544 Problem noted by Paul D. Smith.
8546 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8548 * doc/autoconf.texi: Remove unused words from word list.
8549 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
8550 .x-sc_trailing_space: New files.
8552 * doc/standards.texi: Sync from gnulib.
8554 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
8555 `LIBOBJDIR' as experimental.
8557 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
8558 with a target directory; it's internally implemented as `cp'
8559 anyway, but since Autoconf advertises the possibility to use
8560 a target directory when LN_S is `ln -s', we need to find out.
8561 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
8562 analyzed by Keith Marshall <keith.marshall@total.com>.
8566 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
8568 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
8569 confdefs.h as-is. In general, if it has backslash-newline or the
8570 like, then it doesn't work either to sort or to remove empty
8573 2006-04-09 Stepan Kasal <kasal@ucw.cz>
8575 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
8577 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
8579 * lib/autom4te.in (Automake-preselections): Preselect
8582 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
8584 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
8585 apostrophe within a single-quoted string, as this is the usual
8586 tradition and is easier to read than '"'"'. Don't rely on the
8587 shell treating "$/" like '$/'. Use a more-consistent indenting
8590 2006-04-09 Eric Blake <ebb9@byu.net>
8592 * tests/autotest.at (Backquote command substitution),
8593 (Multiline backquote command substitution): Remove mistaken
8594 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
8596 (Parenthetical command substitution, Multiline parenthetical
8597 command substitution): here.
8599 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
8601 Import macros from gnulib (often changing their name).

8632 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
8633 (C Compiler): Move AC_C_LONG_DOUBLE to ...
8634 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
8635 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
8636 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
8637 (Coding Style). Don't mention m4_expand_once.
8638 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

8677 _AS_DETECT_BETTER_SHELL:
8679 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not

8690 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
8691 distinguish m4sugar macros.
8692 * tests/tools.at (autoupdating with aclocal and m4_include):
8693 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
8694 test case by Noah Misch <noah@cs.caltech.edu>.
8696 2006-04-07 Stepan Kasal <kasal@ucw.cz>

8707 * doc/autoconf.texi (Programming in M4sh): Document that
8708 AS_MKDIR_P exits the script on failure.
8709 * lib/autotest/general.m4: Remove redundant AS_ERROR.
8711 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8730 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8732 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
8733 whether `set' quotes correctly: redirect stderr of the tested
8734 `set', and use a subshell, for Ultrix; use `sed' instead of
8735 `grep' for zsh `set' which may write binary output; match only
8736 at the beginning of a line, to avoid false positives.
8737 In order to avoid false positives by unrelated variables with
8738 multiline content, put the dump algorithm in a subshell and
8739 unset all variables containing newlines (except some which are
8740 special to the shell). Warn about cache variables that are

8786 ac_config_<foo>s again, sometimes normalized, sometimes not.
8787 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
8788 (AC_CONFIG_COMMANDS): Do not do so here.
8789 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
8790 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
8791 2005-07-25 rewrite. Noticed by Noah Misch.
8793 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
8794 _AC_PRESERVE_HELP_ORDER, ...

8801 for --help from Cygnus `configure.'
8803 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

8851 Use simplified args that Eric Blake originally suggested.
8853 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
8855 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
8856 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.

8860 (exclude_list): Exclude empty macros.
8861 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

8947 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
8948 initial `rm' of the candidate files...
8949 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
8950 the same list in subsequent `rm' calls, and for the temporary

8955 no longer needed) by libtool. Make it a cache check.

8957 copied here by mistake.

9676 Factor functionality to..
9677 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
9678 `AC_SUBST($1)' in the public version.
9679 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
9680 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

9705 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
9706 conftest.o, to see whether the compiler really obeys; rm the object
9707 file before and after the test and register it with ac_clean_files.

9710 2005-10-21 Stepan Kasal <kasal@ucw.cz>

9730 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
9731 AC_LANG_PROGRAM, fixing a typo. Don't give details about
9732 the inner workings of AC_LANG_FUNC_LINK_TRY.
9733 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
9734 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
9735 by the function rather than ignoring it.
9736 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
9737 comparing its address. Intel's interprocedural optimization was
9738 outsmarting the old heuristic. Problem reported by
9741 2005-10-19 Stepan Kasal <kasal@ucw.cz>
9743 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
9745 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
9747 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
9748 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
9750 2005-10-04 Stepan Kasal <kasal@ucw.cz>
9752 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
9753 before removing it (chmod -R u+rwx); there are three instances of this.
9755 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9756 Stepan Kasal <kasal@ucw.cz>
9758 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
9759 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
9760 make its content writable before removing it. Remove an errorneous
9761 comment from the end, where the logs of the failed tests are copied
9762 to the main log file.
9764 2005-09-27 Stepan Kasal <kasal@ucw.cz>
9766 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
9767 in case the computer is too quick. Double quote the configure.ac
9770 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
9771 problems if the testsuite were running too fast.
9773 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
9775 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
9776 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
9777 (which belong to Xt, not X itself). See Debian bug 327655.
9778 * NEWS: Mention this.
9780 2005-09-07 Stepan Kasal <kasal@ucw.cz>
9782 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
9784 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
9786 * config/move-if-change: Don't output "$2 is unchanged";
9787 suggested by Ben Elliston. Handle weird characters correctly.
9789 2005-09-06 Stepan Kasal <kasal@ucw.cz>
9791 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
9792 calls, so that the final expansion of this macro is shorter.
9793 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
9794 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
9795 the cleanup there. Use AS_VAR_* macros, to be more general.
9796 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
9798 * lib/autoconf/general.m4: Use AS_IF where appropriate.
9800 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
9802 2005-09-01 Stepan Kasal <kasal@ucw.cz>
9804 * doc/autoconf.texi (Configuration Headers): Add an index entry
9807 2005-08-26 Pavel Roskin <proski@gnu.org>

9810 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
9813 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
9815 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
9816 The previous patch didn't work, so try a better one.
9818 2005-08-26 Stepan Kasal <kasal@ucw.cz>
9820 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
9821 in the example. Reported by Bruno Haible.
9822 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
9823 "if $undefined_var;" succeeds with my shell.
9825 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
9826 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
9827 but change the m4_divert_text to m4_divert_once.
9829 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
9831 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
9832 Work around bug in Solaris /usr/xpg4/bin/awk.
9833 The bug is present in at least Solaris 8 through 10.
9835 2005-08-24 Stepan Kasal <kasal@ucw.cz>
9837 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
9838 some evil values and relying on the fact that $* concatenates the
9839 parameters by the first character from IFS.
9841 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
9842 Stepan Kasal <kasal@ucw.cz>
9844 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
9845 first header appears, define AH_HEADER.
9846 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
9847 Update limitations about when to call AC_CONFIG_HEADERS.
9848 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
9849 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
9850 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
9851 ``Configuration Actions''; fix their index entries.
9853 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
9854 options correctly. Process N-M as M-N if M is smaller than N.
9855 Process ranges correctly so that N-N will run only N.
9856 Sort and uniquify the tests that will be run. If there is more
9857 than one test, reinsert the banners for the tests.
9858 * tests/autotest.at (Keywords): Unmark XFAIL.
9860 2005-08-23 Stepan Kasal <kasal@ucw.cz>
9862 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
9863 before passing the macro name to AH_TEMPLATE.
9865 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
9866 now opens log after option processing; in particular, --version
9867 and --help do not touch config.log.
9869 * Makefile.maint: Revert the change from 2005-08-12.
9871 2005-08-22 Stepan Kasal <kasal@ucw.cz>

9879 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
9880 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
9883 * doc/autoconf.texi (Defining Symbols, Changed Results):
9884 Prepend to LIBS, not append, in examples.
9886 2005-08-16 Stepan Kasal <kasal@ucw.cz>
9888 When building in place, set srcdir="."; suggested by Tim Van Holder.
9890 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
9891 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
9892 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
9893 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
9894 does not mean "no --srcdir option".
9896 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9898 * tests/autoscan.at (autoscan): New file.
9899 * tests/suite.at: Use it.
9900 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
9901 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
9903 * tests/autotest.at (Keywords): Test keywords combinations.
9905 2005-08-12 Stepan Kasal <kasal@ucw.cz>
9907 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
9908 add "2>&1"; gzip 1.2.4 prints help on stderr.
9910 2005-07-27 Stepan Kasal <kasal@ucw.cz>
9912 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
9913 was pushdef'ed twice while popped only once. Push it only once.
9914 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
9916 2005-07-26 Stepan Kasal <kasal@ucw.cz>
9918 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
9919 prefixed by mere "===", not "configure: === ".
9921 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
9923 * Makefile.maint: Update from Bison.
9925 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
9926 "<tab>" in comment, so that the point is understandable.
9928 2005-07-25 Stepan Kasal <kasal@ucw.cz>
9930 Rewrite substantial part of lib/autoconf/status.m4.
9931 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
9932 and CONFIG_COMMANDS are not processed in four separate loops.
9933 Instead, there is one main loop. This alows that the common code
9934 is expanded only once, thus config.status (and configure) is smaller.
9936 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
9937 the AC_LIST_FILES and cousins macros are no longer used.
9939 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
9940 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
9941 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
9942 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
9943 contain the initialization, nor the for loop, nor the associated
9944 commands; all these go to ...
9945 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
9946 _AC_OUTPUT_CONFIG_STATUS.
9947 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
9948 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
9949 (_AC_OUTPUT_FILE): The creation of the sed script ...
9950 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
9951 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
9952 _AC_OUTPUT_MAIN_LOOP.
9953 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
9954 _AC_CONFIG_COMMANDS): Use ...
9955 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
9956 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
9957 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
9958 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
9959 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
9960 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
9962 (_AC_CONFIG_UNIQUE): Update.
9963 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
9964 Replaced by this ...
9965 (_AC_LIST_TAGS): ... new common macro.
9966 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
9967 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
9968 (_AC_LIST_TAG_COMMANDS): ... new common macro.
9969 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
9970 this didn't belong to the `config commands' section.
9971 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
9972 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
9973 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
9974 to the `config commands' section either.
9975 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
9976 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
9978 ... and many changes to the comments nearby.
9980 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
9981 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
9982 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
9983 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
9984 (#define header templates): The comment at the top of the generated
9985 header now includes the name(s) of the source file(s).
9987 Several unrelated small changes:
9989 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
9990 parameter to AC_DIAGNOSE.
9991 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
9992 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
9993 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
9994 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
9996 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
9997 in AC_OUTPUT doesn't double-quote it either.
9998 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
10001 2005-07-10 Stepan Kasal <kasal@ucw.cz>
10003 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
10004 versions of Portland Group compiler produce single- and double-quoted
10005 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
10006 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
10008 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
10010 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
10011 This is a corrected version of yesterday's patch.
10013 2005-07-07 Stepan Kasal <kasal@ucw.cz>
10015 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
10016 path, too; insert a "===" to emphasize the line.
10018 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
10019 ac_cv_build_alias to ac_build_alias.
10020 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
10022 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
10023 change eliminates it. Problem reported by Alexandre Duret-Lutz.
10024 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
10025 (AC_ARG_VAR): ... here.
10026 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
10029 Keep a list of all precious variables and process them with one simple
10030 for loop, instead of expanding all commands, or, OTOH, complicated
10031 processing of output of "set".
10032 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
10033 variable names in new macro...
10034 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
10035 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
10036 a loop to assign all ac_env_* and ac_cv_env_* variables.
10037 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
10039 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
10040 its value to shell variable ac_precious_vars and call
10041 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
10042 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
10043 _AC_ARG_VAR_VALIDATE.
10045 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
10046 and the AC_SUBSTs ...
10047 (AC_INIT): ... here.
10049 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of

10066 2005-07-05 Stepan Kasal <kasal@ucw.cz>
10068 Fix my changes from 2005-07-01; reported by Noah Misch.
10069 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
10070 description, the macro now accepts only a single tag.
10071 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
10073 Fix cases when the varsions of Autoconf and Autotest don't match.
10074 Reported by Noah Misch.

10083 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
10084 Problem reported by Patrick Welche.
10086 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
10088 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
10089 sed substitution command, so that we allow | in program prefixes

10100 for loop over config.site files using `set', to allow
10101 directory names containing IFS characters.
10103 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
10105 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
10106 directories with weird names. Apparently some people like living

10127 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
10128 document to output the default config_* lists to config.status.
10129 Don't recognize option --file, if the functionality is not there.
10130 Likewise for --header; moreover, recognize --he and --h as shortcuts
10131 for --help in that case.
10133 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
10134 matches the order of execution. No code changed.

10153 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
10155 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
10156 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
10157 (AC_SUBST): Call it.
10158 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
10159 the directory specific variables; but don't call it for configure_input.
10161 2005-06-28 Derek Price <derek@ximbiot.com>
10163 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
10166 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
10168 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
10169 directory have inherent problems with special characters like spaces,
10170 due to limitations in Make syntax. Problem reported by Alexandre
10172 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
10173 Also, fix Tru64 porting problem with shell patterns,

10185 from Justace Clutter.
10186 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
10187 variable into diagnostic. Make the diagnostic an error, not a warning,
10188 because we really don't support spaces and suchlike in dir names.
10189 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
10190 Don't worry about backslashes in srcdir; it can't happen now.

10201 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
10203 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
10204 that '\|' is not allowed in BREs; recommend using newline separated
10205 list of patterns instead of multiple -e options.
10207 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
10209 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

10217 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
10218 b, t, r, w commands require single space, while : cannot have any.
10219 (Special Shell Variables): Fix sed code this in the example.
10220 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
10221 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
10223 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
10224 expand to the empty list. Don't use two pairs of m4_changequote,
10225 it's not necessary.
10227 2005-06-20 Derek Price <derek@ximbiot.com>
10229 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
10231 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
10233 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
10234 * doc/autoconf.texi:
10235 Don't mention Solaris versions so much, if a
10236 problem is common to all extant versions of Solaris. Say "SunOS
10237 4" instead of "SunOS" for SunOS 4.
10238 (awk): Mention more of the limitations of traditional Awk.
10239 (cat): Don't talk about cat -v.
10241 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
10243 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
10244 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

10246 to be compatible with glibc strverscmp.
10247 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
10249 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

10252 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
10253 Use shell builtins rather than 'expr', to work around expr bug.
10255 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
10257 * doc/autoconf.texi: "filesystem" -> "file system".
10258 "behaviour" -> "behavior".

10260 * lib/autoconf/general.m4: Omit blank after ":" sed command,
10262 * lib/m4sugar/m4sh.m4: Likewise.
10263 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
10264 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.

10267 (.x.1): Ignore the time stamp in the .TH line when deciding whether
10268 to update the man page. That way, we don't have to check in new
10269 man pages every month.
10271 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
10272 quotes and backslashes. Patch from Derek Price.

10282 -u, since it outputs chatter if the input files are the same.
10283 Problem reported by Ralf Menzel.
10285 2005-06-08 Derek Price <derek@ximbiot.com>
10287 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
10288 renaming them since they are about to be redefined anyhow.
10290 2005-06-08 Derek Price <derek@ximbiot.com>
10292 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
10293 redefined M4 macros to this node. Document m4_include & m4_sinclude.
10294 Move m4_undefine to alphabetical order.
10296 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
10298 * README: Recommend GNU M4 1.4.3 or later.
10299 * doc/autoconf.texi (Introduction): Likewise.
10300 Reword to avoid some formatting glitches.
10301 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
10302 Clarify explanation of HP compiler bug.
10303 Redo example output tp match current CVS snapshot.
10304 Use @example.org in email addresses when the examples
10305 might get inadvertently cut-and-pasted into user code.
10306 Remove example of autom4te usage that doesn't seem to work now.
10307 Use modern AC_INIT (except when the example is meant to be
10308 shown with Autoconf 2.13).
10309 Update ksh info for Solaris 9 and later.
10311 Modernize description of Automake versions a bit.
10312 Don't claim a future version of Autoconf is near.
10313 * doc/install.texi: Reword to avoid some formatting glitches.
10315 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10317 * doc/autoconf.texi: Add [] to examples, so that the manual
10318 follows its own advice about quoting better.
10319 Reword to avoid some formatting glitches.
10320 * doc/installt.exi: Reword to avoid some formatting glitches.
10322 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
10323 Tru64 ksh pattern matching bug. Reported against Libtool by
10324 Albert Chin <libtool@mlists.thewrittenword.com> and
10325 Nicolas Joly <njoly@pasteur.fr>.
10327 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10329 m4_cdr of one-member list was [[]] (one-member list containing an
10330 empty string) instead of [] (an empty list. Callers were skewed to
10331 match this misbehaviour. As a consequence of this:
10332 - m4_foreach([x], [], [foo]) expanded to `foo', while
10333 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
10334 This bug has been fixed:
10336 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
10337 expand to an empty string; print error msg if called without
10339 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
10340 misbehaviour; handle [] and [[]] correctly.
10342 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10344 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
10345 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
10346 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
10348 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
10350 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
10351 swallow records with more than 99 fields.
10352 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
10353 parse the long line.
10355 2005-06-04 Stepan Kasal <kasal@ucw.cz>
10357 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
10358 swallow literals longer than 399. Reported by Ralf Wildenhues.
10359 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
10360 to workaround this limitation.

10364 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
10365 to gfortran, and make these the first two compiler names

10370 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
10371 (DISTCLEANFILES): Remove $(check_SCRIPTS).

10376 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
10377 expression of unbounded size when processing the --list
10378 option. This runs afoul of a limit of 399 bytes per regular
10379 expression on AIX. Problem reported by Ralf Wildenhues.

10388 Reword description of line replacement.
10390 2005-05-31 Dan Manthey <dan_manthey@partech.com>
10392 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
10393 now contain newlines, and substituted files must be referenced on
10394 a line alone; the sed scripts to substitute them are now very
10396 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
10397 commands can be put in a sed script portably.
10398 * doc/autoconf.texi (Setting Output Variables): Document above
10399 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple

10410 * tests/local.at: Don't attempt to check for negated character
10411 classes in shell scripts. The test was too brittle.
10413 2005-05-25 Stepan Kasal <kasal@ucw.cz>
10415 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

10429 messages when ac_unique_file is not found.
10430 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
10431 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
10432 commands, for consistency with AC_MSG_ERROR and such.

10448 (ac_top_builddir): ... this ...
10449 (ac_top_build_prefix): ... to this; the old name is also kept, for
10450 backward compatibility.
10451 (ac_top_builddir_sub): New variable, without the trailing slash,

10467 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
10468 argument to m4_foreach. I guess it was necessary in the past,
10469 but I think it's a no-op now.
10471 2005-05-17 Stepan Kasal <kasal@ucw.cz>
10473 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
10474 ``cat <<_ACEOF'' commands to one.

10548 abbreviations of --version and --debug.
10550 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
10552 * doc/autoconf.texi (Autoconf Language): Be more precise about
10553 quoting rules. Problems noted by Stepan Kasal.
10554 Also, throughout this document, be more careful about white space.
10555 "blank", "white space", and "space" all have different meanings
10556 and we should be careful to say what we mean.
10558 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>

10573 2005-05-02 Gary V. Vaughan <gary@gnu.org>
10575 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
10576 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
10577 set by latest automake.
10579 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
10581 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
10582 outputs 0 on GNU/Linux these days.
10584 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
10586 * doc/autoconf.texi (Autoconf Language): Add more description
10587 about quoting heuristics.
10588 (Limitations of Builtins): Describe "set -" problems.
10590 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10592 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
10595 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
10596 by AC_DEFINE; it was a mistake.
10597 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
10599 2005-04-25 Stepan Kasal <kasal@ucw.cz>
10601 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
10603 2005-04-22 Stepan Kasal <kasal@ucw.cz>
10605 * doc/autoconf.texi (External Software): Quadrigraphs are not
10606 processed correctly in AS_HELP_STRING; avoid this in the examples.
10607 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
10608 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
10609 comment and reduce m4_default([foo], []) to [foo].
10610 (m4_strip): Update the explanation.
10612 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
10614 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
10615 Remove core.conftest.* too; it's generated by Tru64 5.1.
10616 Problem reported by Jennis Pruett.
10617 * lib/autoconf/functions.m4
10618 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
10619 Don't bother to remove core files; AC_RUN_IFELSE should do that
10622 2005-04-19 Stepan Kasal <kasal@ucw.cz>
10624 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

10638 * doc/autoconf.texi (External Software, Package Options): Add
10639 examples showing how to implement --with-* and --enable-* options.
10641 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
10643 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
10644 as well as configure.in. Problem reported by Gregorio Guidi.
10646 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
10648 * doc/autoconf.texi (Particular Functions): Use gnulib's current
10649 pattern for alloca snippet.

10662 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
10664 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10666 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
10667 Merge `-z option' as well for the benefit of Solaris link flags. Pass
10668 whole-archive (-zallextract, -zdefaultextract) options in the hope of
10669 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
10670 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
10672 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
10674 * NEWS: The configure command now warns you if you attempt to use
10675 a directory whose name contains a special character like space,
10677 * doc/autoconf.texi (Installation Directory Variables): Allow
10678 "," in file names. Do not use \@; it's not a portable regexp.
10679 * bin/Makefile.am (edit): Likewise.
10680 * lib/Makefile.am (edit): Likewise.
10681 * tests/Makefile.am (edit): Likewise.
10682 * tests/semantics.at: Likewise.

10685 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
10686 * doc/autoconf.texi (File System Conventions): Warn about
10687 unportable file names.
10688 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
10690 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
10691 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
10692 ac_pwd, and quote srcdir.
10693 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
10695 * doc/autoconf.texi: Fix some systematic formatting problems.
10696 ".)" needs a following @: if not at the end of a sentence, and
10697 similarly for "!)". "etc." should be preceded by a comma.
10698 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
10700 2005-03-22 Bruno Haible <bruno@clisp.org>
10702 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
10703 argument is often called 'build-aux'.
10705 2005-03-07 Stepan Kasal <kasal@ucw.cz>
10707 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
10708 macro AC_TRY_LINK is obsolete.
10709 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
10712 2005-02-24 Stepan Kasal <kasal@ucw.cz>
10714 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
10715 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
10716 from a Common Lisp's `cl'.
10717 (AC_PROG_CXX): Behave according to the documentation: don't
10718 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
10719 make the variable CCC precious; use `cl.exe', not `cl'.
10721 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10722 Alexandre Duret-Lutz <adl@gnu.org>
10724 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
10725 /dev/null, as "configure" shouldn't read stdin, and this insulates
10726 us from problems (e.g., when testing for "cl"). Also, do this
10727 redirection before invoking "hostname" or "uname", and keep the
10728 original input stream available via...
10729 (AS_ORIGINAL_STDIN_FD): ... this new macro.
10730 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
10731 bother with "</dev/null" since it's now done at the top of
10733 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
10734 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

10740 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10742 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
10743 newline if neither \c nor -n work, as that would output two
10744 newlines. Prefer -n to \c. Reported by Stepan Kasal.
10746 2005-02-12 Stepan Kasal <kasal@ucw.cz>
10748 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
10749 This causes that any required macros inside will get before the if.
10750 * doc/autoconf.texi (autom4te.cache): A typo.
10752 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
10754 Undo previous change, except keep the change to
10755 lib/autoconf/programs.m4 that replaced grep with shell
10756 pattern-matching. This is because net-snmp configure reads stdin.
10757 Reported by Noah Misch.
10759 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
10761 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
10762 from /dev/null, as "configure" shouldn't read stdin, and this
10763 insulates us from problems (e.g., when testing for "cl").
10764 Suggested by Alexandre Duret-Lutz. Also, do this redirection
10765 before invoking "hostname" or "uname".
10766 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
10767 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
10768 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
10769 "</dev/null" since it's now done at the top of 'configure'.
10770 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10771 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
10772 Also, replace grep with shell pattern-matching, to save a process.
10774 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
10776 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
10777 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
10778 avoid thinking that Allegro Common Lisp's "cl" command is a C++
10781 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
10783 * doc/autoconf.texi (Limitations of Usual Tools): Document that
10784 grep -q isn't portable. Improve grep -s explanation.
10785 Problem reported by Dan Manthey.
10787 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
10789 * doc/autoconf.texi (Special Shell Variables): Clarify
10790 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
10792 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
10794 * doc/autoconf.texi: Use @acronym for DJGPP.
10795 Fix some @code's that should have been @env's, and vice versa.
10796 Sort environment variable names.
10797 Mention that shells no longer inherit IFS.
10798 Don't recommend PATH_SEPARATOR=';' so strongly.
10799 Mention that $RANDOM might expand to the empty string.
10800 "symlink" and "soft link" -> "symbolic link".
10801 Improve mktemp description (reported by Bruno Haible).
10803 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
10805 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
10806 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
10808 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
10811 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
10813 * NEWS: Mention AT_COPYRIGHT.
10815 * tests/local.at (AT_CMP): Use diff directly on input files rather
10818 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
10819 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
10821 2005-02-04 Noah Misch <noah@cs.caltech.edu>
10822 and Paul Eggert <eggert@cs.ucla.edu>
10824 * tests/autotest.at (Empty test suite): New test.
10825 * tests/torture.at (Substitute and define special characters)
10826 (Substitute a 2000-byte string, Define to a 2000-byte string)
10827 (Substitute a newline, Define a newline): New tests.
10829 2005-02-04 Noah Misch <noah@cs.caltech.edu>
10831 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
10832 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
10833 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
10834 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.

10836 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
10837 excess test name quoting.
10838 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
10839 CPPFLAGS to `configure' instead of setting it in `configure'.
10841 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
10842 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
10845 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
10846 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
10848 * tests/local.at (AT_CMP): New macro.
10849 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
10850 (AC_SAVE_STATE): Move environment grep...
10851 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
10852 (AT_CONFIG_CMP): New macro.
10853 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
10854 * tests/c.at (Extensions): Do not exit early.

10857 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
10858 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
10860 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
10861 (AC_COPYRIGHT): Factor header comment portion out and move into...

10874 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
10876 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
10877 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
10879 Try not to generated lines of unlimited length, as POSIX places a
10880 2047-byte limit on line length of portable text files.
10881 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
10882 Use newline as a separator, not space.

10889 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
10890 as_func_*. Add test to check whether positional parameters
10891 are restored after function return.
10893 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
10895 * doc/autoconf.texi (Special Shell Variables): Mention _,
10896 BIN_SH, DUALCASE. Say that variables other than "status" are safe
10897 if they contain a lower-case letter. The DUALCASE problem was
10898 reported by Ralf Wildenhues.
10900 * bin/autoconf.as: Don't exit with status 0 after write failure
10901 with --help or --version.
10902 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

10907 * doc/autoconf.texi (Limitations of Usual Tools):
10908 Unicos 9 sed limitations.
10909 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
10910 to get the option-enhanced interface on older Crays. Try ftn for
10911 Fortran 95 (newer Crays).
10913 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
10915 * man/Makefile.am (.x.1): Go back to the simple solution, but take
10916 care to echo the commands, so the user knows what's going on.
10917 Modified from a suggestion by Stepan Kasal.
10919 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
10920 with a cross reference. Derived from a suggestion by Bruce Korb.

10924 * doc/autoconf.texi (config.status Invocation): Warn about
10925 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.

10927 Based on a proposed patch by Ralf Wildenhues.
10929 * man/Makefile.am (.x.1): Make sure the required generated files
10930 are up to date. Problem and original solution proposed by Stepan Kasal.

10940 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
10941 Update the long comment explaining it.
10943 m4_require no longer writes an ``is required by'' line to the
10944 execution stack. It contains only one bit of non-redundant
10945 information: that the macro was required, not called. And even
10946 this bit is useless in most situations: have you ever met a macro
10947 which both calls and requires the same macro?
10949 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
10950 (_m4_defun_pro_outer): ... only via this macro, for the outermost

10953 (m4_expansion_stack_pop): Remove the misplaced comment.
10954 (m4_require): Don't put the ``is required by'' line to the

10957 (_m4_require_call): Use it.
10958 * tests/m4sugar.at (m4_require): Expect output without the
10959 ``is required by'' messages.

10995 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
10997 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.

11055 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
11056 stored in _m4_divert_diversion or _m4_divert_dump.
11057 (m4_divert_pop): When the parameter is given, compare the symbolic
11058 name with the last diversion pushed on the stack. Previously, the
11059 current diversion was compared with the numeric value of the
11060 diversion given as the parameter.
11061 (m4_require): If the macro hasn't been expanded yet, call ...

11095 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

11345 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
11346 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
11348 2004-12-07 Stepan Kasal <kasal@ucw.cz>
11350 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

11365 with exactly one parameter.
11367 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
11369 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
11370 "char c = '\200';" rather than "char c = 0x80;" as the
11371 latter doesn't conform to the strict C standard due to

11374 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89

11481 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
11483 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is

11486 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
11488 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
11489 "/usr/include", clear ac_x_includes instead of leaving it as "no"
11490 (trivial change). Problem and patch reported by Andrew Church in:
11491 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
11493 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

11523 Remove ansi2knr.c; nobody uses it.
11524 (ansi2knr.c-url_prefix): Remove.
11525 (cvs-update): Fix test for failure. I don't know why it ever
11528 * doc/autoconf.texi: Update URLs, some of which went stale.
11529 Use @uref rather than @href.
11531 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
11532 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
11534 * config/config.guess, config/config.sub, config/elisp-comp,
11535 config/install-sh, config/mkinstalldirs, config/texinfo.tex,

11545 tests/tools.at, tests/torture.at:
11546 Use "file name" rather than "filename" or "path",
11547 to be consistent with the terminology of the GNU coding standards.
11549 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
11551 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
11552 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
11553 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
11554 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
11556 More fixes to support spaces in the name of the build directory.
11557 This isn't a complete fix but it's an improvement.
11559 * bin/autoconf.as (autom4te_options): New var.
11560 Use it instead of appending to AUTOM4TE, so that we can allow
11561 spaces in the build directory's absolute name.
11562 * bin/autoheader.in ($autoconf): Allow spaces in file names.
11563 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
11564 AT_CHECK_NOESCAPE): Likewise.
11565 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
11566 main program): Likewise.
11568 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
11570 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

11576 * doc/autoconf.texi (Function Portability): Document isinf and
11577 and isnan. From a suggestion by Kevin Ryde.
11579 * lib/Autom4te/General.pm (END): Return correct exit status even
11580 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
11582 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
11584 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
11585 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
11586 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
11588 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
11590 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
11591 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
11592 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
11593 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
11594 * lib/autom4te.in (Automake-preselections): Preselect
11595 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
11597 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
11599 * lib/autom4te.in (Automake-preselections): Preselect
11600 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
11603 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
11605 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for

11608 Document problem with "`""`" in pdksh POSIX mode.
11610 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
11612 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
11613 with pdksh, too. Problem reported by Patrick Welche via
11615 * doc/autoconf.texi (Shellology): Note that set -o posix is
11616 useful for pkdsh, too.
11618 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
11620 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
11621 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
11622 Don't fail if ENV or BASH_ENV is readonly.
11623 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
11624 etc. are read only. Problem reported by Ludovic Courtes.
11626 2004-06-23 Noah Misch <noah@cs.caltech.edu>
11628 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
11629 zsh, disable GLOB_SUBST to avoid backslash handling problems.
11632 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
11634 * doc/autoconf.texi (File System Conventions): Warn about
11635 names like "aux". Problem reported by Eric Blake.
11637 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
11638 by zero instead of array size, so that we can use any arithmetic
11639 constant expression (instead of requiring an integer constant
11640 expression). This allows us to test expressions like DBL_MAX <
11641 LDBL_MAX, which didn't conform to the C standard using the old
11643 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
11644 now that we can do floating-point tests at compile time.
11646 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
11648 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
11649 and LDBL_EPSILON, as the resulting expression isn't an
11650 integer constant expression and violates the C standard.
11651 Problem reported by Nelson H. F. Beebe. Also, check
11652 for "L" suffix, and check that long double doesn't have
11653 worse range or precision than double, that mixed-mode
11654 arithmetic doesn't generate a diagnostic, that double
11655 constants fit in long double.
11657 2004-06-03 Kevin Ryde <user42@zip.com.au>
11659 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
11660 malloc(0) and realloc(NULL,size).
11662 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
11665 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
11667 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
11668 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
11671 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
11673 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
11674 can be rewritten using if-then-else. Suggested by Bruno Haible.
11676 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
11678 * doc/autoconf.texi (testsuite Scripts): Fix typo.
11679 Problem reported by Stepan Kasal.
11681 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
11683 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
11684 change). Patch reported by Ralf Wildenhues in
11685 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
11687 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
11688 function F exists if the compiler and linker let you compile an
11689 expression like (F != 0). Recent versions of GCC optimize away
11690 the reference to F in that case, since every function address must
11691 be nonzero, so the link succeeds even if F does not exist.
11692 Problem reported by Manu in
11693 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
11695 * doc/autoconf.texi (Systemology): Standardize on the spelling of
11696 "Unix". Many uses changed.
11697 (Limitations of Builtins): Explain better why the ! command isn't
11700 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
11702 * lib/autom4te.in (Automake-preselections): Preselect
11703 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
11705 2004-05-19 Kevin Ryde <user42@zip.com.au>
11707 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
11708 referencing AC_FUNC_STRERROR_R.
11710 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
11711 note pessimistic assumption when cross compiling.
11713 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
11715 * doc/autoconf.texi (Limitations of Make): Note that BSD make
11716 (until 2004) invoked subcommands with sh -e, contra POSIX.
11717 Reported by Kevin Ryde.
11719 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
11721 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
11722 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
11723 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
11724 `test -f " /usr/bin/grep"', which _always_ failed.
11725 (AC_PROG_SED): Ditto bogus PATH fix.
11726 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
11727 requires that grep correctly supports _multiple_ `-e' options, rather
11728 than stating only that grep should accept `-e'.
11730 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
11732 Port to C99, which requires that 'exit' be declared.
11734 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
11735 to ensure that stdlib.h is included.
11736 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
11737 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
11738 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
11739 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
11740 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
11741 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
11742 when using 'exit' in a test; C99 requires that 'exit' be declared.
11744 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
11746 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
11747 now prefers 'grep' implementations that accept -e.
11748 (Limitations of Usual Tools): Describe problems of traditional
11749 egrep and fgrep with long input lines, and of traditional grep
11751 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
11752 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
11753 All callers changed. Append /usr/xpg4/bin to the PATH, for
11755 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
11756 the user with complaints about multiple -e options.
11757 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
11758 Define it with AC_PROG_GREP.
11759 * configure.ac (AC_PROG_GREP): Add.
11760 * lib/freeze.mk (GREP): New macro.
11762 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
11764 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
11765 a possible candidate only after all others fail, rather than
11766 consulting it first. This improves backward compatibility by
11767 better reflecting the way shell selection occurred in previous
11768 versions of Autoconf, and should help to avoid triggering latent
11769 problems in other packages, such as the one in Automake where zsh
11770 is not handled robustly:
11771 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
11772 Although it is not Autoconf's responsibility to work around
11773 problems in Automake, it nevertheless makes sense to avoid
11774 introducing unnecessary incompatibilites.
11776 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
11777 Gary V. Vaughan <gary@gnu.org>
11779 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
11780 how deeply nested we are when a suitable tool is found, set the
11781 ac_path_TOOL_found flag.
11782 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
11783 nested we are in this macro. Break out of all 3 nested loops if
11784 ac_path_TOOL_found is set.
11786 2004-04-21 Gary V. Vaughan <gary@gnu.org>
11788 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
11789 of the _AS_PATH_WALK loop too if GNU flavor is found.
11791 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
11793 * doc/autoconf.texi (Limitations of Make): Update documentation
11794 for `$<'. New entry `Long lines', based on a report from Simon
11795 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
11796 paragraph about DJGPP, based on a mail from Richard Dawe.
11798 2004-04-20 Paul Eggert <eggert@twinsun.com>
11800 * tests/c.at (C keywords): Don't assume that GCC supports
11801 "restrict" and "inline", as sufficiently-old GCC versions do not
11802 (also, GCC configured to be in pedantic C89 mode does not).
11803 Problem reported by Sumit Pandya in:
11804 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
11806 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
11807 consider -g to work if it generates warnings when plain compiles
11808 don't. Problem reported by Braden McDaniel in:
11809 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
11811 * doc/autoconf.texi (Slashes): New section, to document a problem
11812 reported by Jim Meyering in:
11813 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
11815 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential

11822 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
11823 best tool so far counter rely on the tool path variable name to
11824 avoid checks for one tool being affected by the results of running
11825 the length check on a previous tool.
11827 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
11828 match expression argument, as different greps have different
11829 regular expression flavours.

11860 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
11861 now defines HAVE_DECL_TZNAME if it is declared, when
11862 HAVE_STRUCT_TM_TM_ZONE is not defined.
11863 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
11864 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

11911 behavioral changes.
11912 * tests/mktests.sh: Do not generate tests for the
11914 * NEWS: Document these changes.
11916 * doc/autoconf.texi: Avoid macros with unbraced arguments,

11933 * bin/Makefile.am (edit): Don't use $< in a context where
11934 POSIX doesn't require support for it. Use $@.in instead.
11935 Problem reported by Anthony N. Frasso in
11936 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

11942 from the next generation of Libtool.
11943 * lib/autom4te.in (Autoreconf-preselections): Ditto.
11945 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
11947 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
11948 is not always thread-safe. Report from Nathanael Nerode.

11952 Fix a dependencies problem, stemming from a Autoconf 2.59 build
11953 problem on QNX reported by Stephen Rasku in
11954 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
11956 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
11957 $(m4sh_m4f_dependencies); this removes a FIXME.
11958 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
11959 (MAINTAINERCLEANFILES): Split into pieces,
11960 one per related section. Add $(srcdir)/wrapper.in.
11962 2004-02-09 Paul Eggert <eggert@twinsun.com>
11964 * doc/autoconf.texi (Setting Output Variables): Emphasize that
11965 AC_SUBST provides no portable way to escape literal newlines.
11967 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
11968 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
11969 Darwin uses -lcrt2.o and there's little point to cataloging all
11970 the system variants. Partial fix reported by Andreas Waechter in:
11971 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

11987 the behavior of the third argument.
11988 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
11989 correctly the behavior of the third argument. Document
11990 what the three macros that AU_DEFUN defines do. Fix
11991 warning message when the third argument includes $0

11995 Eric Sunshine <sunshine@sunshineco.com>
11996 Paul Eggert <eggert@twinsun.com>
11998 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
11999 (AS_INIT): Output shell initialization there. Removed optional
12000 parameter. Expand _AS_SHELL_FN_SPY.

12009 (_AS_RUN): Move it here, support testing with eval.
12010 (AS_REQUIRE_SHELL_FN): Require shell functions when
12012 (_AS_LINENO_WORKS): Put around braces, we do not
12013 trigger the bash bug anymore.
12014 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
12015 use AS_INIT_WITH_SHELL_FN.
12016 * bin/autoconf.in, tests/wrapper.in: Regenerated.
12018 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

12024 (AU_DEFUN): Honor the third parameter, create autoupdate
12025 macros with AU_DEFINE.
12026 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
12027 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

12046 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

12048 the 2003-05-22 change, which removed the older years from the list.
12049 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
12051 2004-01-27 Gary V. Vaughan <gary@gnu.org>
12052 Albert Chin-A-Young <china@thewrittenword.com>

12060 egrep and fgrep respectively if $GREP -E/-F don't work.
12061 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
12062 _AC_PROG_GREP, and AC_PROG_SED.
12063 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
12064 longest input length accepted by a command.

12093 2004-01-26 Paul Eggert <eggert@twinsun.com>
12095 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
12096 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
12097 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
12098 not <inttypes.h>. Problem reported by Tim Mooney in
12099 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
12100 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
12103 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
12104 otherwise "make check" fails because it forbids cmp (I guess
12105 because cmp treats files as binary on DOS-like systems).
12107 * tests/mktests.sh: Update copyright date to 2004, since some tests
12108 have changed in 2004.
12110 2004-01-23 Gary V. Vaughan <gary@gnu.org>
12112 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
12113 non-truncating sed or gsed program in PATH.
12114 * tests/acprograms.at: Add it.
12115 * doc/autoconf.texi (Particular Programs): Document it.
12118 2004-01-15 Paul Eggert <eggert@twinsun.com>
12120 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
12121 -std1 disables some useful extensions on Tru64. Problem reported
12122 by N. Lichtmaier in
12123 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
12125 2004-01-14 Paul Eggert <eggert@twinsun.com>
12127 * doc/autoconf.texi (Programming in M4sh): Document that
12128 AS_MKDIR_P succeeds if the destination is a symbolic link
12129 to an existing directory.
12130 (Limitations of Usual Tools): Note that mkdir -p might not
12131 succeed on symlinks to directories.
12133 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
12135 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
12136 * bin/autoheader.in: Grammar fix in message.
12137 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
12138 Test for dir before calling mkdir -p. (trivial changes)
12140 2004-01-13 Eric Blake <ebb9@byu.net>

12145 2004-01-10 Jim Meyering <jim@meyering.net>
12147 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
12149 2004-01-09 Paul Eggert <eggert@twinsun.com>
12151 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
12152 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
12153 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
12154 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
12155 AC_COMPILE_IFELSE, since we now assume our caller invokes
12156 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
12157 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
12158 of AC_RUN_IFELSE; this avoids the warning mentioned above.
12159 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
12161 2004-01-07 Paul Eggert <eggert@twinsun.com>
12163 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
12164 `"'...'"`, as it's confusing (and I suspect it may not work on
12165 some platforms). The code was incorrect anyway, as it assumed
12166 that \$ evaluated to itself in that context. Reported by
12167 Alexandre Duret-Lutz.
12169 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
12171 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
12172 and _LT_AC_TAGCONFIG.
12174 2004-01-06 Paul Eggert <eggert@twinsun.com>
12176 * doc/autoconf.texi (One Macro Call): Fix an incorrect
12177 example, and add more examples. Reported by Eric Sunshine.

12195 by doing lineno substitution only on lines containing "$LINENO".
12197 2004-01-04 Paul Eggert <eggert@twinsun.com>
12199 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
12200 Use "rm -f" to remove conftest.sed, not plain "rm".
12201 Bug reported by David Relson in
12202 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
12204 * Makefile.am (autom4te-update):
12205 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

12221 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
12222 -c -o might not work. From a suggestion by Kevin Ryde.
12223 (C Compiler, Generating Sources, Limitations
12224 of Usual Tools, Limitations of Make, Making testsuite Scripts):
12225 Don't put '-o' after non-options, as POSIX doesn't allow this.
12226 Mention that cc's name might be gcc or c89 or whatever.
12228 2004-01-04 Kevin Ryde <user42@zip.com.au>
12230 * doc/autoconf.texi: Add various further index entries.
12232 2003-12-29 Paul Eggert <eggert@twinsun.com>
12234 * bin/autoreconf.in (autoreconf_current_directory):
12235 Fix typo: mkdir without umask arg.
12237 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
12239 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
12240 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

12242 explanation clearer.
12244 2003-12-24 Andreas Schwab <schwab@suse.de>

12527 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

12553 cache variable instead of $G77 to decide whether to include -O2,

12564 arguments so that it can be used with syntax identical to

12566 remove/deprecate the DIALECT optional argument in the future if it
12567 proves troublesome.
12568 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
12569 non-freeform-supporting compilers. Document freeform flags.
12571 2003-10-03 Akim Demaille <akim@epita.fr>

12640 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
12641 directory for AC_CONFIG_COMMANDS' first argument exists.
12642 This makes valid the invocation of _AC_SRCPATH that follows.
12643 Reported by Eric Sunshine.

12667 The test suite are sometimes assigning timings incorrectly.
12668 Reported by Henk Krus.
12669 Diagnosed by Nicolas Joly.
12671 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
12673 Instead of making AT_help a sequence of assignments to grow

12675 $at_help_all, and make a single assignment in...
12677 (at_times_skip): Flip the meaning and rename as...
12678 (at_times_p): this.

12689 (ifnames): chmod -w.
12690 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
12691 executables, not bin/ executables! Otherwise all the magic needed
12692 to find non installed files is turned off. This caused a failure
12693 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
12694 as found in its environment (sent by tests/autoreconf): pointing
12695 to bin/autom4te that could not find its files.
12696 * tests/mktests.sh: Force the replacement of generated files, for
12697 the sake of "mv" program that are interactive when overwriting a

12926 2003-08-21 Akim Demaille <akim@epita.fr>
12928 First stab at preserving warnings between calls to autom4te,
12929 including when the cache is used.
12931 There are still several issues: (i) there are too many runs of m4
12932 (one for include, one for warnings, and some more), (ii) warnings
12933 spreading on several lines are not handled gracefully, (iii) the
12934 code meant to have the call stack display for errors does not work
12935 (its handling should move from m4 to autom4te).
12937 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
12939 (@preselect): Add m4_warn.
12940 ($exit_status): Remove, use $exit_code.
12941 ($help): Use Autom4te::ChannelDefs::usage.
12942 (&handle_m4): No longer define the m4_warnings.
12943 At each run, extract and report the warnings.
12944 Always cache the result, including if the exit status is on
12945 failure, since if nothing changes, we should result in the same
12946 failure, hence we can use the cache.
12947 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
12948 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
12950 (m4_warn): Redefine as a do-nothing: it is its invocation that
12951 matters, as warnings are now reported via traces.
12952 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
12953 the contents of m4_warn: make it _call_ m4_warn, so that tracing
12954 the latter reveals calls to the former.
12958 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
12960 2003-08-21 Akim Demaille <akim@epita.fr>

12980 (&catfile): Remove.
12981 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
12982 * bin/autoscan.in: Adjust.
12984 2003-08-20 Akim Demaille <akim@epita.fr>
12986 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
12987 Reported by Alexandre Duret-Lutz.
12989 2003-08-20 Akim Demaille <akim@epita.fr>
12991 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
12992 * bin/autom4te: Adjust.
12993 In particular, be Autoconf tools are really silent when properly
12994 working, bind the verbosity of the 'note' channel to $verbose.
12995 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
12996 (&xsystem, &contents): Remove, since they are exported by...
12997 * lib/Autom4te/FileUtils.pm: this.

13000 * lib/Autom4te/FileUtils.pm: here.

13119 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
13120 not all of them. This fixes 1. the fact that when testing

13123 Don't mix the detailed output of failed test with the summary of

13230 exit 63, so that we (or Automake's "missing") can tell the
13231 difference with a plain failure.
13232 * doc/autoconf.texi (Notices): Adjust.
13234 2003-05-23 Akim Demaille <akim@epita.fr>
13236 * Makefile.am, bin/Makefile.am, config/Makefile.am,
13237 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:

13241 Paul Eggert <eggert@twinsun.com>
13243 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
13244 Remove `#include <stdlib.h>' from the list; we should never
13245 make confdefs.h include <stdlib.h> or <cstdlib>, because the
13246 resulting namespace pollution would cause other tests to fail.
13247 Configure scripts run with some older versions of g++ and HP's
13248 aCC would fail due to such an #include. Problems reported by
13249 Matthew Mueller in <http://bugs.debian.org/120704> and by
13251 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
13252 In the test, use the test declaration before including <stdlib.h>,
13253 as that's closer to how it'll be used.
13255 2003-05-23 Akim Demaille <akim@epita.fr>
13257 * doc/autoconf.texi (Header Portability): ucred.h.
13260 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
13262 Overhaul Autotest's logging: generate separate log files
13263 in testsuite.dir/NNN/testsuite.log, and append them to
13264 testsuite.log instead of re-running the test verbosely.
13266 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
13267 file descriptor, write 0 to at_status_file instead of setting
13268 at_status=0, initialize some new variables (at_status_file,
13269 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
13270 to rerun the tests, instead append the at_group_log to the
13271 at_suite_log when a test fails.
13272 (AT_SETUP): pipe the test case's output into at_tee_pipe,
13273 with the AS_MESSAGE_LOG_FD redirected to stdout.
13274 (AT_CLEANUP): save the output status in $at_status_file
13275 and restore it, redirect the AS_MESSAGE_LOG_FD back to
13276 its original place.
13277 (AT_CHECK): since tests are run with a redirected stdout,
13278 and used to be re-run in verbose mode, turn some $at_verbose
13279 into echo, and don't redirect the output of testing stdout
13282 * lib/autotest/autoconf.texi (testsuite Scripts): Update
13283 the name of the debugging directory and information about

13403 2003-05-06 Akim Demaille <akim@epita.fr>
13405 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
13406 longer updates aclocal.m4 if useless, (ii) if a file m4_included
13407 by aclocal.m4 is changed it might require the importing of another
13408 m4 extension file, i.e., aclocal must be run.
13410 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
13411 (&parse_args): Use --force with aclocal if required and supported.

13425 2003-04-29 Derek Price <derek@ximbiot.com>
13427 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
13428 seperator with m4_append_uniq(). It doesn't work.
13429 (AT_CLEANUP): Add `;' to end of at_help_all.
13430 (AT_INIT): Allow --keywords to be specified more than once. When
13431 grepping $at_help_all for keywords, use the field and keyword
13432 seperators to ensure a complete keyword match. Alter at_prev handling
13433 to support the new --keywords behavior.
13435 2003-04-27 Karl Berry <karl@freefriends.org>
13437 * doc/autoconf.texi: Make the dir entries in the autoconf manual
13438 align better with others. I also made some of the individual
13439 entries on one line, for brevity and to make it easier for me to
13440 sort my dir-example file in the Texinfo distribution :).

13507 header causes problems.
13509 2003-03-28 Akim Demaille <akim@epita.fr>
13511 * tests/torture.at (Configuring subdirectories): Require aclocal
13512 1.4, otherwise the test fails, as it does support configure.ac.

13586 (Automake): Automake 1.5+ no longer requires special tools to be
13587 present on the developer's host.

13633 format starting with "-".
13635 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>

13638 is not portable inside Makefile.
13640 2003-02-20 Akim Demaille <akim@epita.fr>
13642 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When

13644 Conversely, prompt the reader to send a bug report to the
13645 maintainers of the package, not of Autoconf.
13647 2003-02-20 Klee Dienes <kdienes@apple.com>

13660 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
13661 innocuous variant befor including <limits.h> or <assert.h>. This
13662 works around a bug reported by Albert Chin: HP-UX 11i
13663 (and earlier versions) have a <limits.h> that declares
13664 gettimeofday and many other functions.
13666 2002-12-03 Paul Eggert <eggert@twinsun.com>
13670 * NEWS, configure.ac: Update version.

13674 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
13675 nontrivially in main's body, so that f's external declaration is
13676 not optimized away in AIX. This should fix the bug reported by
13678 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
13680 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
13681 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
13682 defined, to support freestanding compilers. This should fix the
13683 bug reported by Momchil Velkov in
13684 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
13686 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
13687 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
13688 obsolete AC_CHECK_TYPE. The missing empty arg was reported

13690 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
13692 * Makefile.maint (www-gnu): New macro.
13693 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
13694 the location has moved.
13696 2002-12-02 Martin Frydl <martin@systinet.com>
13698 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
13699 \(.*\) match is too long and there is something more to be checked.
13700 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

13718 Update from masters.
13720 2002-11-14 Akim Demaille <akim@epita.fr>
13722 * Makefile.maint: Sync with Bison, i.e.:
13723 (po-check): Scan .l and .y files instead of the
13724 .c and the .h files that they generate. This fixes the bug
13725 reported by Tim Van Holder in:
13726 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
13727 Look for N_ as well as for _. Try to avoid matching #define for

13748 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
13749 option. Process --recheck after parsing all options. Pass -q
13750 option to configure on --recheck.

13782 Reported by Ezra Peisach.
13784 2002-11-05 Akim Demaille <akim@epita.fr>
13786 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
13788 We _have_ to stop using the old compatibility scheme that tried to
13789 avoid useless backslashes because Libtool 1.4.3 contains a
13790 AC_DEFINE([error_t], [int],
13791 [Define to a type to use for \`error_t' if it is not
13792 otherwise available.])
13793 We _have_ to quote the single quote and backslashes with \. The
13794 old compatibility scheme saw that ` was backslashed, and therefore
13795 did not quote the single quote. Hence before this patch, Autoconf
13796 was not compatible with Libtool.

13841 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
13842 Make variable, not a shell variable.
13843 Suggested by Bruno Haible.

13870 Problem reported by Bruno Haible.

14187 Reported by Alexandre Duret-Lutz.
14189 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

14210 if some file was changed instead of `print'.
14211 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
14212 (&parse_args): Remove the dead options.
14213 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
14214 autoheader's quiet mode.
14215 (AT_CHECK_AUTOUPDATE): Likewise.
14216 * tests/tools.at (autoupdate): Adjust.
14217 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
14219 2002-10-11 Akim Demaille <akim@epita.fr>
14221 No longer use CPP to check for the existing of headers: use CC to
14222 check for compilability.
14224 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
14225 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
14226 (_AC_CHECK_HEADER_NEW): Rename as...
14227 (AC_CHECK_HEADER): this.
14229 * lib/autotest/general.m4 (AT_INIT): Include the failed test
14230 numbers in the Subject suggestion.
14232 2002-10-11 Akim Demaille <akim@epita.fr>
14234 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
14235 Suggest using AC_CHECK_DECLS instead.
14237 2002-10-11 Akim Demaille <akim@epita.fr>
14239 * tests/torture.at (AC_ARG_VAR): Have configure report the value
14242 2002-10-11 Akim Demaille <akim@epita.fr>
14244 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
14245 file name to enable parallel executions.
14246 From Sam Varshavchik.
14248 2002-10-08 Akim Demaille <akim@epita.fr>
14250 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
14251 aclocal invocation, as Gettext macros might not be visible to
14253 Instead of blindly running autopoint, scan configure.ac (not the
14254 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
14255 Reported by Paul D. Smith.
14257 2002-10-08 Paul Eggert <eggert@twinsun.com>
14259 Work around problems found when POSIXLY_CORRECT=1 is set.
14260 None of this seems to have anything to do with POSIX, really,
14261 but it's how Perl getopt works.
14262 * bin/autom4te.in (parse_args): Configure GetOpt with
14264 * doc/autoconf.texi (Invoking autom4te):
14265 --warning -> --warnings.
14266 * lib/autom4te.in: --warning -> --warnings.
14268 2002-09-28 Akim Demaille <akim@epita.fr>
14270 * doc/autoconf.texi (autom4te.cache): New section.
14272 2002-09-28 Akim Demaille <akim@epita.fr>
14274 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
14275 (Automake-preselections): Update.
14276 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
14278 2002-09-28 Akim Demaille <akim@epita.fr>
14280 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
14281 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
14282 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
14283 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
14285 2002-09-28 Akim Demaille <akim@epita.fr>
14287 * tests/torture.at (Configuring subdirectories): Be robust to
14288 users who use config.site to require for a cache: in this case,
14289 the two last configure runs, using two different sets of
14290 arguments, trigger a legitimate error.
14292 2002-09-28 Akim Demaille <akim@epita.fr>
14294 * tests/m4sh.at (Functions Support, Functions and return Support):
14297 2002-09-28 Akim Demaille <akim@epita.fr>
14299 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
14300 autoheader are Perl programs.
14301 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
14302 (autom4te): Specify that the sources are in the $srcdir.
14303 * doc/autoconf.texi (Installation Directory Variables): Adjust.
14305 2002-09-28 Akim Demaille <akim@epita.fr>

14310 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
14311 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
14312 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
14313 * lib/autoconf/programs.m4: here.

14323 that were listed in the original autoscan.list.
14324 * lib/autoconf/headers.m4: Similarly with headers.
14325 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
14326 (.m4.m4f): Don't pass --prepend-include, since that's done by
14327 tests/autom4te itself.
14328 * lib/autoscan/Makefile.am: Include freeze.mk.
14329 (autoscan.list): New target --this file is no longer a source.
14330 (autoscan.pre): New file.
14332 2002-09-28 Akim Demaille <akim@epita.fr>
14334 * bin/autoscan.in (@kinds): Make them singular.
14336 (&init_tables): When --debug, report the list of rules to ease
14337 tracking changes in autoscan.list.
14338 * lib/autoscan/autoscan.list (function): Strip comments, sort.
14340 2002-09-28 Akim Demaille <akim@epita.fr>
14342 * lib/autoscan/functions, lib/autoscan/headers,
14343 * lib/autoscan/identifiers, lib/autoscan/makevars,
14344 * lib/autoscan/programs: Merge into...
14345 * lib/autoscan/autoscan.list: this.
14346 * bin/autoscan.in (&init_tables): Adjust.
14348 2002-09-28 Akim Demaille <akim@epita.fr>
14350 * lib/autoscan/functions, lib/autoscan/headers,
14351 * lib/autoscan/identifiers, lib/autoscan/makevars,
14352 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
14353 `functions' line is now prefixed with `function:'.
14354 * bin/autoscan.in (&init_tables): Adjust.
14356 2002-09-28 Akim Demaille <akim@epita.fr>
14358 From now on, autoscan files must always map a macro name to a
14359 word: there is no `default' macro for autoscan.
14361 * bin/autoscan.in (&init_tables): Reject entries with no macro at
14363 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
14366 2002-09-28 Akim Demaille <akim@epita.fr>
14368 * bin/autoscan.in (%c_keywords): Remove.
14369 (&used): Keep only track of the words we might be interested in.
14370 (&output_kind): It is no longer needed to look for non active
14373 2002-09-27 Akim Demaille <akim@epita.fr>
14375 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
14376 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
14377 * lib/autoscan/functions: Adjust.
14378 * doc/autoconf.texi (Particular Functions): Adjust.
14380 2002-09-27 Akim Demaille <akim@epita.fr>
14382 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
14384 Thanks to Bill Moseley and Paul Eggert.
14385 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
14386 the tmpdir must be created.
14387 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
14388 dir be in the build tree, instead of $TMPDIR.
14390 2002-09-27 Akim Demaille <akim@epita.fr>
14392 * bin/autoscan.in: Improve the comments.
14393 (&parse_args): Drop obsolete undocumented options.
14394 (&output_kind): Output warnings.
14395 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
14396 (getwd): Trigger a warning.
14398 2002-09-26 Akim Demaille <akim@epita.fr>
14400 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
14401 Reported by Ralf Corsepius.
14402 * doc/autoconf.texi (autoreconf Invocation): Likewise.
14404 2002-09-26 Akim Demaille <akim@epita.fr>
14406 Single suffix rules and seperated dependencies are not portable.
14408 * doc/autoconf.texi (Installation Directory Variables): Update.
14409 (Limitations of Make): Some about `Single Suffix Rules and
14410 Separated Dependencies'.
14411 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
14412 (ifnames, autoscan, autom4te): Un-factor into several rules.
14414 2002-09-25 Paul Eggert <eggert@twinsun.com>
14416 * BUGS (Interoperability bugs): New section. Mention libtool
14417 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
14419 2002-09-24 Paul Eggert <eggert@twinsun.com>
14421 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
14422 make handles suffix-rules differently from GNU make.
14424 * bin/Makefile.am (SUFFIXES, .in): Remove.
14425 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
14426 Move the body of the old .in rule here.
14428 2002-09-16 Akim Demaille <akim@epita.fr>
14430 i960 compilers create `b.out' files by default.
14431 Reported by Ralf Corsepius.
14433 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
14434 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
14436 2002-09-13 Paul Eggert <eggert@twinsun.com>
14438 * doc/autoconf.texi (Particular Headers): Remove obsolete
14439 reference to `struct timezone' in the description of
14442 2002-09-13 Akim Demaille <akim@epita.fr>
14446 * config/config.sub, config/config.guess: Update.
14447 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
14448 * Makefile.am: Adjust.
14450 2002-09-13 Akim Demaille <akim@epita.fr>
14452 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
14453 reading config.log when the compiler is rejected.
14454 Suggested by Guido Draheim.
14456 2002-09-13 Akim Demaille <akim@epita.fr>
14458 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
14459 (chdir_init) might hang when stat'ing mounted directories.
14460 Reported by Vance Shipley.
14462 2002-09-12 Akim Demaille <akim@epita.fr>
14464 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
14467 2002-09-12 Akim Demaille <akim@epita.fr>
14469 * doc/autoconf.texi (Defining Symbols): Present two different
14470 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
14471 difference between 1 argument calls, and 2-3 argument calls.
14473 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
14475 * doc/autoconf.texi: Review grammar and punctuation.
14477 2002-09-11 Paul Eggert <eggert@twinsun.com>
14479 * doc/autoconf.texi: Fix minor formatting, spelling, and
14481 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
14482 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
14485 2002-09-11 Akim Demaille <akim@epita.fr>
14487 * doc/autoconf.texi (Questions): Rename as...
14489 (Defining Directories): New.
14491 2002-09-09 Akim Demaille <akim@epita.fr>
14493 * doc/autoconf.texi (Making testsuite Scripts): Update.
14494 Suggested by Nishio Futoshi.
14496 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
14498 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
14499 plain `@' is wanted.
14501 2002-09-09 Akim Demaille <akim@epita.fr>
14503 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
14504 `duplicates', since the algorithm was too naive and could keep
14505 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
14506 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
14507 Reported by Ralf Corsepius.
14508 * tests/torture.at (Configuring subdirectories): Exercise these
14511 2002-09-09 Akim Demaille <akim@epita.fr>
14513 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
14514 looking for a replacement file.
14515 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
14516 directory is relative.
14517 * doc/autoconf.texi (Generic Functions): Clarify the replacement
14518 directory definition.
14519 Reported by Andreas Schwab and Jim Meyering.
14521 2002-09-06 Akim Demaille <akim@epita.fr>
14523 * doc/autoconf.texi (Setting Output Variables): Clarify what
14524 precious variables are.
14525 Suggested by Pontus Skoeld.
14527 2002-09-05 Akim Demaille <akim@epita.fr>
14529 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
14530 (ifnames, autoscan, autom4te): Since we don't only depend on
14531 configure.ac variables (such as VERSION etc.), but also on prefix
14532 and so forth, depend on Makefile, not configure.ac.
14533 Reported by Alexandre Duret-Lutz.
14534 * doc/autoconf.texi (Installation Directory Variables): Adjust.
14536 2002-09-05 Kevin Ryde <user42@zip.com.au>
14538 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
14539 doesn't seem to be confined to ia64, just say "some versions".
14541 2002-09-04 Akim Demaille <akim@epita.fr>
14543 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
14545 * Makefile.am (maintainer-clean-local): Remove.
14546 (MAINTAINERCLEANFILES): Remove COPYING.
14548 2002-09-03 Paul Eggert <eggert@twinsun.com>
14550 * doc/autoconf.texi (Configuration Commands): Remove obsolete
14551 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
14554 2002-09-03 Akim Demaille <akim@epita.fr>
14556 * configure.ac: Bump to 2.53d.
14557 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
14558 as of today, on Automake's team suggestion.
14560 2002-09-03 Akim Demaille <akim@epita.fr>
14564 2002-09-02 Akim Demaille <akim@epita.fr>
14566 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
14568 * configure.ac: Disable SITE_MACRO_DIR.
14570 2002-09-02 Jim Meyering <meyering@lucent.com>
14572 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
14573 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
14574 Also, tweak grammar: s/make sure to/be sure to/.
14576 2002-09-02 Paul Eggert <eggert@twinsun.com>
14578 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
14579 directory names are generally preferable to physical names.
14581 2002-09-02 Akim Demaille <akim@epita.fr>
14583 * lib/Autom4te/General.pm (&update_file): s/die/error/.
14584 Reported by Raja R. Harinath.
14585 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
14586 * bin/autoupdate.in: Use error instead of die.
14588 2002-09-01 Paul Eggert <eggert@twinsun.com>
14590 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
14591 ordinary shell concatenation rather than echo+tr+sed command that
14592 runs afoul of a long-line-related sed bug in Solaris 8.
14594 * bin/autoheader.in (parse_args): --warning -> --warnings.
14596 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
14597 stdout, as traditional "ls" does.
14598 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
14599 _AC_COMPILER_EXEEXT_O): Likewise.
14600 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
14602 * bin/autoconf.as: Add --prepend-include option. This patch was
14603 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
14604 but bin/autoconf.in is generated automatically from bin/autoconf.as.
14606 * bin/autoconf.in, configure: Regenerate.
14608 * doc/autoconf.texi (Special Shell Variables): Mention
14609 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
14611 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
14612 MAILPATH and set PS1, PS2, PS4 to default values, to work
14613 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
14614 For LC_ALL etc, first try to set to "C" as POSIX requires and as
14615 the Autoconf documentation specifies; fall back to "unset" only if
14616 this fails. Use a shell for-loop for this rather than an m4 loop,
14617 to shorten the output script.
14619 2002-08-30 Paul Eggert <eggert@twinsun.com>
14621 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
14622 1003.1-2001's requirements for CDPATH. Give a simpler workaround
14623 for the CDPATH problem. Document PWD.
14624 (Limitations of Builtins): Document the problem that "cd $foo" and
14625 "ls $foo" may refer to different directories in shells conforming
14626 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
14627 example, since the old example is now out of date.
14629 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
14630 FOO" and "ls FOO" talk about different directories; this catches
14631 problems when POSIX 1003.1-2001 "cd" fails due to symlink
14634 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
14635 of rolling our own unset.
14636 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
14637 in practice we needn't worry about CDPATH if unset doesn't work.
14639 * Makefile.in, aclocal.m4, bin/Makefile.in,
14640 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
14641 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
14642 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
14643 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
14644 tests/Makefile.in: Regenerate with Automake 1.6.3.
14646 * config/config.guess, config/config.sub, config/mkinstalldirs:
14649 * configure: Regenerate with self.
14651 2002-08-30 Kevin Ryde <user42@zip.com.au>
14653 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
14656 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
14658 * bin/autom4te.in (Request::load): Correctly test for "do" read
14661 2002-08-29 Akim Demaille <akim@epita.fr>
14663 * lib/Autom4te/General.pm (&xqx): New.
14664 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
14665 hand, which is not portable.
14667 * bin/autom4te.in: Use them.
14668 Use &error instead of die.
14669 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
14672 2002-08-17 Paul Eggert <eggert@twinsun.com>
14674 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
14675 default list of compilers to try, since it was long ago superseded
14676 by the ksh fc builtin. Suggested by Steven G. Johnson.
14678 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
14680 * doc/autoconf.texi (Invoking autom4te): End the option table,
14681 fixing a bug introduced by the previous patch.
14682 (Limitations of Make): Add a 'target lookup' subentry in the
14683 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
14685 2002-07-29 Mark D. Roth <roth@feep.net>
14687 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
14688 options and use $AUTOM4TE_PATH.
14689 * doc/autoconf.texi: Remove documentation of autom4te
14690 --include-envvar and --site-macro-subdir options and document
14691 use of $AUTOM4TE_PATH.
14692 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
14693 arguments from each language section.
14695 2002-07-29 Paul Eggert <eggert@twinsun.com>
14697 * doc/install.texi: Include copyright symbol in copyright notice.
14699 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.

14992 This improves on an earlier suggestion by H. Peter Anvin.
14994 2002-05-16 Paul Eggert <eggert@twinsun.com>
14996 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
14997 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
14998 Both macros now accept an optional source-dir arg.
14999 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
15001 * NEWS: Document this.
15002 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
15004 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
15005 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
15006 not for GNU extensions; this undoes part of the 2000-11-03 change,
15007 reverting to 2.13-compatible behavior.

15009 (AC_FUNC_FNMATCH_GNU): New macro.

15015 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
15016 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
15017 and it causes a 'test' syntax error if it fails.
15018 Bug reported by Stephen Gildea.
15020 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
15021 If prototypes are supported, use them to check this at compile-time,
15022 instead of trying to check it at run-time. If we must do a run-time
15023 check, assume that setvbuf is standard when cross-compiling, as
15024 nonstandard setvbuf occurs only on ancient and unlikely hosts.
15025 Bug reported by Paul D. Smith.
15027 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
15028 argument specifying location of getloadavg.c. This removes a
15029 FIXME. This idea was taken from Jim Meyering's implementation in
15031 * doc/autoconf.texi (Particular Functions): Document this.
15032 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
15033 that's what the code does; this fixes a bug reported by

15039 autopoint instead of gettextize.
15040 ($uses_alocal): Rename as...
15041 ($uses_aclocal): this.
15042 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15043 Suggested by Bruno Haible.

15051 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
15052 files to be 1 second older; just set them to be the same time.
15053 Also, sleep 1 second after the first aclocal, to work around
15054 problems with sub-second time stamps on the input files.
15056 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
15058 * doc/autoconf.texi: Mention "set -e -x" lossage

15067 2002-04-29 Akim Demaille <akim@epita.fr>
15069 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
15070 of lack of $LINENO support, then the test will compare the $LINENO
15071 in testsuite vs. the lineno in the test file. This is wrong, of
15073 Be sure to protect it.
15074 Reported by Patrick Welche.
15076 2002-04-25 Akim Demaille <akim@epita.fr>
15078 * doc/autoconf.texi (Obsolete Macros): Typo.
15079 Reported by Vladimir Volovich.
15081 2002-04-25 Akim Demaille <akim@epita.fr>
15083 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
15084 than some of the input files, hence, on the second run of aclocal,
15085 if some of its input are younger, make them older.
15086 Suggested by Paul Eggert.
15088 2002-04-25 Akim Demaille <akim@epita.fr>
15090 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

15099 (_AC_INIT_PREPARE): Use them to log them.
15100 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
15101 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
15102 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
15103 _AC_SUBST_FILES and _AC_SUBST_VARS.
15104 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
15106 2002-04-24 Akim Demaille <akim@epita.fr>
15108 * bin/autoreconf.in (autoreconf): Run automake after autoconf and

15196 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
15198 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
15199 from aclocal.m4 too.
15201 2002-04-12 Akim Demaille <akim@epita.fr>
15203 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
15205 2002-04-10 Akim Demaille <akim@epita.fr>
15207 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
15208 workaround for ${1+"$@"}.
15209 * doc/autoconf.texi (Shell Substitutions): Explain it.
15210 From Oliver Kiddle and Peter Stephenson.
15212 Have M4sh perform minimal shell sanitizing.
15214 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
15216 (_AS_PREPARE): this new macro.
15218 (AS_INIT): Invoke AS_SHELL_SANITIZE.
15219 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
15221 Adjust Autoconf and Autotest.
15223 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
15224 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
15225 * lib/autotest/general.m4 (AT_INIT): Likewise.
15226 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
15227 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
15230 Use this M4sh to generate Autoconf's shell scripts.
15232 * tests/wrapsh.as: New, precursor of wrapsh.in.
15233 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
15234 on Autotest and M4sh.
15235 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
15236 (wrapsh.in): New target.
15237 * bin/autoconf.as: New, precursor of autoconf.in.
15238 (autoconf.in): New target.
15240 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

15243 with indented comments in rules.

15258 directories when descending in a SUBDIRS.
15259 Reported by Ezra Peisach.
15261 2002-04-04 Andreas Schwab <schwab@suse.de>
15263 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
15264 contains no literal separators.
15266 2002-04-03 Akim Demaille <akim@epita.fr>
15268 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
15269 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
15270 Use dnl, not the KILL diversion.
15272 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
15273 (AC_CONFIG_LINKS): here.
15275 Don't use the KILL diversion, as it kills spurious output, which
15276 results in failures being hidden.
15277 Use m4_defn where appropriate.
15278 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
15279 after the second argument.
15281 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
15282 syntax, as it is provided by M4sugar.
15283 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
15285 2002-04-03 Andreas Schwab <schwab@suse.de>

15304 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
15306 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.

15310 (AC_C_CONST): Same.
15311 (AC_C_INLINE): Same.

15320 _AS_MKDIR_P_PREPARE.
15322 2002-03-28 Kevin Ryde <user42@zip.com.au>
15324 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
15325 to avoid versions of HP C which don't allow that.
15327 2002-03-27 Paul Eggert <eggert@twinsun.com>
15329 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
15330 (AS_SHELL_SANITIZE): Invoke it.
15331 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

15337 2002-03-26 Akim Demaille <akim@epita.fr>
15339 * doc/autoconf.texi (Introduction): The GNATS base moved.
15341 2002-03-25 Paul Eggert <eggert@twinsun.com>
15343 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
15344 as POSIX requires, as it doesn't work with Zsh.
15345 * doc/autoconf.texi (Assignments): Document the problem.
15347 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
15349 * doc/autoconf.texi (Limitations of Make): Mention more issue
15350 about VPATH, overriding of macros in sub-makes, and handling of
15353 2002-03-21 Paul Eggert <eggert@twinsun.com>
15355 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
15356 problem with here-document buffer boundaries.
15358 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
15359 when reinvoking the shell, to work around problems with installers
15360 who put strange things like "cd" commands in their environments.
15362 2002-03-19 Akim Demaille <akim@epita.fr>
15364 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

15376 From Nishio Futoshi.
15378 2002-03-19 Akim Demaille <akim@epita.fr>
15380 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

15384 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
15385 (Limitations of Usual Tools): Add mkdir section.
15387 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
15388 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
15389 back on AS_DIRNAME to compute prefixes otherwise; this is
15390 roughly what mkinstalldirs does. That way, we need not have
15391 our own filename disassembler. The old disassembler did not
15392 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
15394 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
15395 Create at_test_all by a series of assignments,
15396 not by a single assignment of a long string. The latter causes ksh
15397 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
15398 presumably because of a buffer overrun.
15400 2002-03-14 Paul Eggert <eggert@twinsun.com>
15402 * lib/autotest/general.m4 (at_times_skip):
15403 Renamed from at_times. Now a boolean.
15404 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
15405 says 'times: not found'.
15407 2002-03-14 Akim Demaille <akim@epita.fr>
15409 * bin/autoreconf.in (&study_gettextize): New.
15410 (&autoreconf): Handle newest gettextize.

15434 2002-03-11 Andreas Schwab <schwab@suse.de>
15436 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
15437 does not do it if --with-lispdir is given.

15446 subdirectory should exist.
15448 2002-03-08 Akim Demaille <akim@epita.fr>
15450 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
15452 2002-03-08 Akim Demaille <akim@epita.fr>
15454 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
15455 aliases the actual variables, and modifications of the former
15458 2002-03-08 Akim Demaille <akim@epita.fr>
15460 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
15461 because of C-c: have m4 output in tmp files, then mv them.

15484 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
15485 * lib/autoconf/general.m4 (AC_INIT): More informative error
15486 message for LIBOBJ.
15488 2002-03-04 Akim Demaille <akim@epita.fr>

15493 2002-03-04 Akim Demaille <akim@epita.fr>
15495 * doc/autoconf.texi (Transforming Names): Equality between target
15496 and host is irrelevant.
15497 (Specifying Names, Canonicalizing): Remove all references to the
15498 backward compatibility hooks. Rather, collect them all into...
15499 (Hosts and Cross-Compilation): this new section.
15500 * doc/install.texi (System Type): Ditto.
15501 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
15502 that `--host' implies cross-compilation.
15504 2002-03-04 Akim Demaille <akim@epita.fr>
15506 * doc/autoconf.texi (Evaluation Macros): New.
15507 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
15509 (_m4_foreach): Define the variant with immediate evaluation so
15510 that it contains exactly the items, not an expression which
15511 evaluation is the current item.
15512 (m4_re_string, m4_re_word): Don't over quote them.
15514 2002-03-04 Akim Demaille <akim@epita.fr>
15516 Instead of having stacking `shift's evaluated at the end, let
15517 `foreach' loops immediately evaluate them.
15519 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
15520 $*. This is the n-th time I change my mind, but hopefully this is
15523 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
15525 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
15526 it was only a hack for m4_text_wrap.
15527 (m4_car2): Remove, replaced by...
15529 (_m4_foreach): Adjust.
15530 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
15531 m4_bpatsubst for clarification.

15582 Fix Autoconf PR/207:
15583 AC_PREFIX_PROGRAM fails with dashed program names
15585 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
15586 variable when looking for the prefix program.
15587 Now it also works for shell variables.

15622 2002-02-05 Akim Demaille <akim@epita.fr>
15624 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

15646 * bin/autom4te.in (&parse_args): Implement `frozen files are
15647 optional are the sum of the previous files on the command line'.
15648 Also, pass `--reload-state=' on them, so...
15649 (handle_m4): don't.
15650 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
15651 (M4sh): Rely on M4sugar.
15652 (Autotest, M4sh, M4sugar): Use frozen files.

15668 is now run with GCC only.

15678 2002-01-29 Akim Demaille <akim@epita.fr>
15680 * tests/torture.at (Configuring subdirectories): Use configure.in,
15681 so that aclocal 1.4 works.
15682 Reported by Alexandre Duret-Lutz and Larry Schmitt.
15684 2002-01-28 Akim Demaille <akim@epita.fr>
15686 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
15689 2002-01-28 Akim Demaille <akim@epita.fr>
15691 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
15692 AUTOTEST_PATH *after* it was set.
15693 Don't put `.' in the PATH: the user should be precise and `./' if
15694 needed. In addition, given that the test suite does some `cd', if
15695 `.' is in the path, the `tested programs' sections will report
15696 programs found in the test suite's directory, while during the
15697 tests (performed in their own directory), these programs are no
15698 longer visible. In other words, the results is confusing and
15700 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

15765 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
15766 package.m4, since is really depends upon configure.ac, not
15768 * doc/autoconf.texi (testsuite Scripts): Adjust.
15769 * tests/Makefile.am (package.m4): New.
15770 EXTRA_DIST it since its a source.
15772 2002-01-06 Akim Demaille <akim@epita.fr>
15774 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
15775 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
15776 and PACKAGE_BUGREPORT from here...
15777 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
15779 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
15780 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

15804 2001-12-14 Akim Demaille <akim@epita.fr>
15806 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
15807 trailing files, don't apply `-rf' to files which might not be
15808 created by configure (core, core.*, and *.core), but just `rm -f'.
15809 Suggested by Jonathan Kamens.
15811 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
15813 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

15817 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
15819 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

15822 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
15823 abs_srcdir, top_srcpath to abs_top_srcdir.
15824 (_AC_OUTPUT_FILES): Adjust.
15825 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,

15835 2001-12-12 Kevin Ryde <user42@zip.com.au>
15837 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
15838 forbidden file descriptors table.
15840 2001-11-26 Akim Demaille <akim@epita.fr>
15842 * bin/autoscan.in (%c_keywords): Build it at top level.

15848 Remove $filepath, useless.
15849 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
15850 variables, they are really part of the tokens.
15851 Split the input line on spaces and then look for tokens.
15852 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
15853 because of `lex$U.$(OBJEXT)'.
15854 (&scan_files): Use "@list" instead of join.
15855 * doc/Makefile.am (CLEANFILES): Add *.fns.

15860 Remove, replaced by...
15861 * tests/wrappl.in: Be common for all the Perl executables.
15862 In particular autoscan and autoheader want -I.
15863 * configure.ac: Adjust.
15864 * lib/autoscan/headers: errno.h is portable.
15866 2001-11-26 Akim Demaille <akim@epita.fr>
15868 * bin/autoscan.in (used): New.
15871 2001-11-26 Akim Demaille <akim@epita.fr>

15875 (&scan_sh_file): Remove a duplicate pattern.
15876 (&check_configure_ac): Use long options.

15881 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
15882 Before, having a line containing the opening of a multi line
15883 comment made the whole line be ignored.
15885 2001-11-26 Akim Demaille <akim@epita.fr>
15887 * doc/autoconf.texi (Using an Autotest Test Suite): New.

15893 Test groups are now run two directories deeper.
15895 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
15896 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
15898 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
15899 top_srcdir, builddir and top_builddir.
15900 Use `at_*dir' relatively to the directory containing the
15901 suite, use `*dir' when relatively to the current group dir.
15903 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
15905 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
15906 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
15907 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
15910 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
15912 * doc/autoconf.texi (Using System Type): Add an example of `case
15913 $host' usage so people quit using `case $target' everywhere.
15915 2001-11-22 Akim Demaille <akim@epita.fr>
15917 * doc/autoconf.texi (Installation Directory Variables): Englishoes
15918 spotted by Jim Meyering.
15920 2001-11-16 Paul Eggert <eggert@twinsun.com>
15922 This patch implements a `long double' suggestion by Oliver Kiddle.
15924 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
15925 static, to catch errors if the value isn't known at compile-time
15926 and the compiler supports dynamic arrays. Change its name from
15927 `_array_' to `test_array' to avoid potential name clashes.
15928 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
15929 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
15930 better than double. Catch a bug in GCC 2.95.2 x86.
15931 * doc/autoconf.texi (C Compiler): Document the above.
15934 2001-11-13 Akim Demaille <akim@epita.fr>
15936 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
15938 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
15940 2001-11-13 Akim Demaille <akim@epita.fr>
15942 * lib/autotest/general.m4 (AT_INIT): After having run the test
15943 group, go back to the initial directory, not to at_suite_dir.
15945 2001-11-13 Akim Demaille <akim@epita.fr>
15947 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
15948 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
15949 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
15951 (AT_CHECK_CONFIGURE): Use absolute paths.
15952 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
15953 The problem is still the old one: there is no means in M4 (that I
15954 know about) to create a defining macro, because there is no means
15955 to create `$1' etc., therefore, the defining macro ``swallows''
15956 all the arguments meant to the defined macro.
15958 2001-11-13 Akim Demaille <akim@epita.fr>
15960 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
15961 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
15963 * tests/aclocal.m4: Remove, as it is no longer used.
15965 2001-11-13 Akim Demaille <akim@epita.fr>
15967 * lib/autotest/general.m4: Change `tests?' into `groups?' in
15968 variable names when referring to a single test group, or to
15969 `suite' when referring to the whole test suite.
15970 `at_last_test' is removed: m4 compute at_format itself.
15971 (at_stdout, at_stder1, at_stderr): New variables.
15972 (AT_CHECK): Use them.
15974 2001-11-13 Akim Demaille <akim@epita.fr>
15976 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
15978 Create `testsuite.dir/003/run' instead of `testsuite.003'.
15979 Do it as soon as a test fails, don't wait till the end of the test
15981 Don't remove $as_me.[0-9]*, since these files no longer exist.
15983 2001-11-13 Akim Demaille <akim@epita.fr>
15985 * tests/tools.at: Use absolute paths, since we are no longer run
15988 2001-11-13 Akim Demaille <akim@epita.fr>
15990 Now that tests are running in their own private dir, there is no
15991 need to list the files to remove at the end of tests groups.
15993 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
15994 (AT_data_files, at_data_files): Remove.
15995 (AT_CLEANUP, AT_DATA): Simplify.
15997 Remove the group dir if !debug && !failed.
15998 * tests/atspecific.m4: Adjust.
16000 2001-11-13 Akim Demaille <akim@epita.fr>
16002 Start a new layout for Autotest: `testsuite' creates
16003 `testsuite.dir' in which the at-check-line etc. files are to be
16004 found, and `testsuite.dir/003' where the test group 3 is run.
16006 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
16007 at_check_line_file, at_format, at_test_normalized, at_group_dir
16009 Create the directories.
16010 Use absolute paths for at- files.
16011 (AT_CHECK): Adjust.
16013 2001-11-11 Michael Matz <matz@kde.org>
16015 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
16017 (m4_car): Properly quote arguments.
16019 2001-11-13 Akim Demaille <akim@epita.fr>
16021 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
16022 with stricter rules on LIBOBJS.
16024 2001-11-12 Paul Eggert <eggert@twinsun.com>
16026 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
16027 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
16030 2001-11-12 Akim Demaille <akim@epita.fr>
16032 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
16034 2001-11-12 Akim Demaille <akim@epita.fr>

16037 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
16038 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
16039 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
16040 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
16041 specify to what the macro should be defined (typically to 1).
16043 2001-11-12 Akim Demaille <akim@epita.fr>
16045 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
16048 2001-11-12 Akim Demaille <akim@epita.fr>
16050 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
16051 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
16052 definition used by Automake where LEX is +/- "${missing} lex" and
16053 `missing' itself contains variables.
16055 2001-11-12 Akim Demaille <akim@epita.fr>
16057 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
16058 Now that M4sh pushes BODY, the comments were output at the end of
16061 2001-11-08 Akim Demaille <akim@epita.fr>
16063 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
16064 that we can trace macros from aclocal.m4.
16065 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
16066 obsoleted, and redirect to the former anyway.
16067 Reported by Ralf Corsepius.
16069 2001-11-08 Akim Demaille <akim@epita.fr>
16071 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
16072 processed only if present.
16073 * tests/torture.at (Configuring subdirectories): Use autoreconf
16074 instead of successive calls to autoconf.
16075 Add a nonexistent subdirectory to exercise the patch above.
16076 Reported by Ralf Corsepius.
16078 2001-11-08 Kevin Ryde <user42@zip.com.au>
16080 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc

16088 * bin/autom4te.in (warn_forbidden): New.
16089 (handle_output): Use it.
16090 Read m4_pattern_forbid with messages.

16094 * bin/autom4te.in (--normalize): Remove.
16095 * lib/autom4te.in: Adjust.
16097 2001-11-05 Akim Demaille <akim@epita.fr>
16099 * tests/Makefile.am (testsuite): Rename this target as...
16100 ($(TESTSUITE)): this.
16103 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
16105 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
16106 the --prefix option, also remove it's argument.
16108 2001-11-05 Akim Demaille <akim@epita.fr>
16110 * doc/autoconf.texi (testsuite Invocation): Update.
16111 (Writing testsuite.at): Update.

16120 (&file_name_is_absolute): New, wrappers around routines from
16122 Use and export them.
16123 (&find_configure_ac): Optionally take a directory where to look at.
16124 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
16126 Default @ARGV to `.', not find_configure_ac.
16127 (&autoreconf): Argument is a directory.
16128 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
16129 * doc/autoconf.texi (autoreconf Invocation): Update.

16138 Don't look for aclocal flags if we already know aclocal is not
16140 Move aclocal.m4t only if it exists.
16141 Reported by Ezra Peisach.
16143 2001-11-03 Akim Demaille <akim@epita.fr>
16145 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
16146 passed on command line, defaulting to ./configure.ac if present.
16147 (&maybe_autoreconf, File::Find): Remove, unused.
16148 (&autoreconf): If autoconf is not used, don't try to trace.
16150 2001-11-02 Akim Demaille <akim@epita.fr>

16167 Don't run aclocal when aclocal.m4 is not from aclocal.
16169 Don't run libtoolize and gettextize if --install is not given.
16171 2001-11-01 Paul Eggert <eggert@twinsun.com>
16173 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
16174 be invoked before _AS_LINENO_PREPARE.
16175 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
16176 than character ranges.
16178 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
16179 invoking AS_BASENAME. Set the locale variables to 'C' if
16180 possible, as POSIX requires this to get the traditional

16187 with {}, as that triggers a bug in Bash 2.05.
16189 (_AS_LINENO_PREPARE): Use Sed rather than
16190 Awk. Fix the sed prepass to work even if there are multiple
16191 instances of $LINENO on the same line. Do not substitute for
16192 other variables like $LINENOT. Do not check file dates; such a
16193 check is unreliable on sufficiently fast machines, and removing
16194 the check makes the code simpler and more reliable. Check for
16195 output and chmod failures.
16197 * doc/autoconf.texi (Special Shell Variables): Document
16200 2001-10-31 Akim Demaille <akim@epita.fr>
16202 * tests/Makefile.am (atconfig): Remove this target, Automake
16205 2001-10-31 Akim Demaille <akim@epita.fr>
16207 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
16208 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
16209 provided, while it is optional.
16210 * configure.ac: Adjust.
16212 2001-10-26 Paul Eggert <eggert@twinsun.com>
16214 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
16215 lib/Autom4te/Struct.pm:
16216 Require Perl 5.005_03 instead of just 5.005, as some tests fail
16219 * doc/autoconf.texi (Special Shell Variables): Document some
16220 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
16222 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
16223 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
16224 eval $LINENO is not portable in practice.
16226 2001-10-24 Akim Demaille <akim@epita.fr>
16228 * lib/Autom4te/General.pm (backname): New.
16230 2001-10-24 Akim Demaille <akim@epita.fr>

16240 2001-10-22 Paul Eggert <eggert@twinsun.com>
16242 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
16243 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
16244 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
16245 POSIX decided to standardize on the int flavor of strerror_r.
16246 Always do char* test, as there's no reason not to.
16247 Assign to a char* var, to catch strerror_r that returns int*.
16249 * doc/autoconf.texi (Particular Functions):
16250 Document the above changes. Also, document the fact that
16251 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
16253 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
16255 2001-10-20 Akim Demaille <akim@epita.fr>

16265 * bin/autoreconf.in: No longer support --m4dir.
16266 (&autoreconf): Display the full path of the configure.ac we are
16268 Trace it only once.
16269 Be sure to honor --force with gettextize.
16270 Always run aclocal.
16271 * doc/autoconf.texi: Adjust.
16273 2001-10-20 Akim Demaille <akim@epita.fr>
16275 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
16277 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
16278 `intl' is already present, as it refuses unless --force.
16279 (&parse_args): Use -I, --include instead of the old Autoconf
16281 ($localdir, $autoconf_dir): Remove.
16283 (&maybe_autoreconf): New, to preserve $_ for File::Find.
16285 2001-10-19 Jens Petersen <petersen@redhat.com>
16287 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

16300 comment, explain how to install automatic mode selection.
16303 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
16305 * bin/autoreconf.in (autoreconf): Display the path to the
16306 configure.ac being studied.
16308 2001-10-18 Paul Eggert <eggert@twinsun.com>
16310 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
16311 long, to work around a bug in the HP C compiler version HP92453-01
16314 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
16315 (AS_BASENAME_EXPR): New macro.
16316 (AS_BASENAME_SED): Do not assume GNU sed semantics.
16317 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
16318 and fall back on 'sed' only if the other two fail. This makes
16319 AS_BASENAME act more like AS_DIRNAME.
16320 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
16321 contains white space.
16322 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
16323 Use AS_DIRNAME, since I think it's now DOS-friendly.
16324 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
16325 Allow "dirname //FOO" to return either / or //, as POSIX allows
16328 2001-10-10 Akim Demaille <akim@epita.fr>
16330 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

16336 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

16374 (Syntax of the shell scripts): Don't.
16375 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
16376 bother with $force since...
16377 * lib/Autom4te/General.pm: does.
16379 2001-10-08 Akim Demaille <akim@epita.fr>
16381 * bin/autoreconf.in: Rewrite in Perl.
16382 * configure.ac: Adjust.

16466 empty, and if we can find a shell that does support LINENO,
16467 then set CONFIG_SHELL to that shell and then re-execute
16468 ourselves with CONFIG_SHELL.

16472 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
16473 doesn't exist. Remove *.tmp, as a .tmp file is created during the

16554 Check for `expr' arithmetic overflow, and for compilation failure,
16555 and invoke a new argument $4 if either is discovered.
16556 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
16557 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
16559 2001-09-28 Akim Demaille <akim@epita.fr>

16591 * tests/fortran.at (GNU Fortran 77): there.
16592 * doc/autoconf.texi (autoconf Invocation): Fix the example:
16593 AC_TRY_RUN is about compilation, not shell commands.

16607 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

16700 2001-09-22 Akim Demaille <akim@epita.fr>

16705 `$LINENO' support replacement when not supported.
16706 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

16751 arguments. Fixed a typo.
16753 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
16755 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
16756 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.

16773 2001-09-19 Akim Demaille <akim@epita.fr>
16775 * lib/autotest/general.m4: Englishoes.
16776 From Tim Van Holder and Alexey Mahotkin.
16778 2001-09-18 Paul Eggert <eggert@twinsun.com>
16780 * doc/autoconf.texi (Common Shell Constructs): New node,
16781 documenting AS_DIRNAME.
16782 (Limitations of Usual Tools): Refer to it when discussing dirname.
16783 Also, update discussion of POSIX standard to reflect latest draft.
16785 * lib/autoconf/c.m4:
16786 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
16788 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
16789 Do not pass a first argument with leading '-'
16790 to expr, by parenthesizing initial integers that might be negative.
16792 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
16793 now merely checks whether it is an error to pass an argument
16796 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
16797 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
16798 whether it is a (compile-time) error to pass an argument to
16799 getpgrp. This simpler test supports the revised documentation,
16800 and is all that AC_FUNC_GETPGRP's users really need.
16802 2001-09-18 Akim Demaille <akim@epita.fr>
16804 * doc/autoconf.texi (Limitations of Make) <$<>: New.

16814 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
16816 Add test for AS_BASENAME.
16817 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
16818 added test. It now correctly handles /1/2/3/, returning '3' not ''.
16819 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
16820 * tests/base.at: Fixed the expected responses. The old ones were
16822 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
16823 the documentation claims it should (and how it behaved in 2.13).
16825 2001-09-18 Akim Demaille <akim@epita.fr>
16827 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
16828 the AC_CONFIG_COMMANDS invocation.
16829 This also solves the name clash problems.
16830 Don't set the package's ID.
16831 * lib/m4sugar/Makefile.am (version.m4): Revamp.
16832 No longer to be shipped.
16833 (version.in): Remove.
16834 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
16835 * lib/autoconf/status.m4: Adjust.
16836 Use `m4_PACKAGE_STRING'.
16837 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
16838 the only optional argument is the name of the test suite.
16839 Expect `package.m4' to define the package signature.
16840 * lib/autom4te.in (Autotest): Add `package.m4?'.
16841 * tests/Makefile.am (package.m4): New.
16842 * tests/suite.at: ifnames is a victim.
16844 2001-09-18 Akim Demaille <akim@epita.fr>
16846 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
16847 AC_LIBSOURCE, AC_CONFIG_FILES.
16848 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
16849 program version string doesn't match the package's.
16850 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

16855 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
16856 Allow expression to return any value that can fit into unsigned long

16861 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
16862 Always include <stdio.h> and <stdlib.h>. Evaluate
16863 the expression in an extra function before these includes. Call
16864 fprintf "%d" only after ensuring the argument is of type 'int'.
16865 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
16867 2001-09-17 Paul Eggert <eggert@twinsun.com>
16869 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
16870 or CFLAGS=-O5. In that case, the linker has a relaxed view of
16871 fatal errors, and AC_CHECK_LIB causes it to include libraries even
16872 when they don't exist.
16874 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
16875 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
16878 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
16879 version with the version used by fileutils 4.1, except use
16880 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
16883 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
16885 2001-09-13 Akim Demaille <akim@epita.fr>

16925 * lib/autotest/general.m4 (AT_INIT): Create and remove
16926 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
16927 test suites can cohabit.

16931 * tests/mktests.sh: Don't output banners for empty test files.

16983 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

16986 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

17037 2001-09-05 Akim Demaille <akim@epita.fr>
17039 Be ready to handle filenames as stupid as `dnl.at', for if even
17040 the maintainer is dumb enough to do that...
17042 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
17043 excellence in M4 quotation: consider `__file__' is active.
17045 And BTW, when invoking m4, pass the --include in the right order:
17048 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

17124 2001-08-31 Akim Demaille <akim@epita.fr>
17126 * man/Makefile.am (.x.1): We really have to pass
17127 autom4te_perllibdir.

17137 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
17138 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
17139 Use directly autom4te, not autoconf.
17140 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
17142 2001-08-31 Akim Demaille <akim@epita.fr>

17164 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.

17181 Drop AC_MACRODIR dead for real.
17182 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
17183 `autoheader: `config.hin' is created'.
17184 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
17186 2001-08-31 Akim Demaille <akim@epita.fr>
17188 * bin/autoheader.in: Rewrite in Perl.

17194 Map --localdir, --autoconf-dir onto it.
17195 Forward autom4te's options instead of interpreting them.
17196 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
17197 There is no such envvar since the inception of autom4te.cfg.

17219 * lib/Autom4te/General.pm (&find_peer): Remove.
17220 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

17222 * man/Makefile.am: Let help2man rely on PATH instead of trying to
17223 find the executables for it.

17225 * tests/atlocal.in: Remove all the obscure envvar manipulations.
17227 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
17228 indeed related to running the test suite, while passing
17229 --autoconf-dir and others is related to running non installed
17230 Autoconf executables. So don't do that, leave it to...

17232 * tests/autoscan: New.
17233 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

17250 Suggested by Paul Eggert.
17252 2001-08-29 Akim Demaille <akim@epita.fr>
17254 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
17255 download in a tmp dir.
17257 2001-08-29 Akim Demaille <akim@epita.fr>
17259 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

17279 foo=`(command) 2>/dev/null`

17430 the name of the directory they're in, instead of the filename,

17574 Huh!?!?! There are still some user EOF tags used, which prevents
17575 their use in AC_CONFIG_COMMANDS for instance...

17578 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

17722 2001-08-15 Akim Demaille <akim@epita.fr>
17724 * bin/autom4te.in (@m4_warning): New.
17725 (&handle_m4): Use it.
17726 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
17727 warnings are issued at each run.

17729 is in the src tree.
17731 2001-08-15 Akim Demaille <akim@epita.fr>

17796 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
17798 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
17799 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
17800 * doc/autoconf.texi (C Compiler Characteristics): Update
17801 documentation for AC_C_BIGENDIAN.

17806 magic values from an object file when cross-compiling.
17807 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
17809 2001-08-10 Akim Demaille <akim@epita.fr>
17811 * bin/autom4te.in (&handle_output): Don't use `grep' with side
17813 Suggested by Russ Allbery.
17815 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
17817 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
17818 current $prefix to the sub-configures.
17820 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
17822 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
17823 extension (needed on BeOS). Reported by Guido van Rossum.
17825 2001-08-09 Akim Demaille <akim@epita.fr>
17827 * bin/autom4te.in ($icache): Load it only if older than autom4te.
17829 2001-08-07 Akim Demaille <akim@epita.fr>
17831 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
17833 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
17834 No need to remove the files before and after the each test, before
17835 each test and at the end of the suite is enough.
17836 Display only the children `times', not the shell's.
17837 If the test failed or was skipped, at-times is not available.
17839 2001-08-07 Akim Demaille <akim@epita.fr>
17841 Always produce testsuite.log, including when there are no
17842 failures. This helps getting information on skipped tests, and
17843 duration of the tests. Err, implement the latter btw.
17845 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
17846 Dump information on the first run of each test.
17847 (AT_CLEANUP): Create `at-times' containing the duration of the
17850 2001-08-07 Akim Demaille <akim@epita.fr>
17852 The use of `dumpstat' revealed that `len' was used although it
17853 should not. m4_text_wrap was using it, but in the Autoconf world
17854 where it is legal. Hence (i) test M4sh in its own world, not
17855 Autoconf's, and (ii), ahem, fix the bug :)
17857 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
17858 does not like `' instead of [].
17859 (AT_INIT): Forbid `^_?AT_'.
17860 And don't output such tokens.
17861 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
17862 `script.as', and `autom4te.cache'.
17863 Remove `empty' and `macro' which are no longer used.
17864 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
17865 * tests/m4sugar.at: Use it.
17866 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
17868 2001-08-07 Akim Demaille <akim@epita.fr>

17874 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
17876 2001-08-04 Akim Demaille <akim@epita.fr>
17878 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
17879 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
17881 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
17882 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
17883 (AC_F77_MAIN): Likewise.
17885 2001-08-04 Akim Demaille <akim@epita.fr>
17887 Don't rely on M4sugar outputting the patterns in files, since we
17888 might process the output _without_ running m4, hence without these
17891 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
17892 * bin/autom4te.in (@Request::includes): Remove, unused.
17893 (@Request::source): Rename as...
17894 (@Request::input): this.

17898 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
17899 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
17901 2001-08-04 Akim Demaille <akim@epita.fr>
17903 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
17904 autoconf', i.e., in addition to caching traces, cache the output.
17906 * bin/autom4te.in (Request::cache): Rename as...
17907 (Request::id): this.
17908 ($cache, $icache, $tcache, $ocache): New.
17909 (&handle_m4): Save M4 output in the cache instead of $tmp.

17911 (&up_to_date_p): Check that the output cache is up to date too.
17912 (top level): Run `&handle_m4' iff force or the cache is invalid.

17915 2001-08-04 Akim Demaille <akim@epita.fr>
17917 * bin/autom4te.in ($force): New.
17918 (&parse_args, &print_usage): -f, --force is a new option.
17919 (&handle_output): CPP directives might have spaces after `#'.
17920 (&parse_args): The first file only can be frozen.
17922 2001-08-04 Akim Demaille <akim@epita.fr>
17924 Don't let autom4te compute the `include' traces several times:
17925 first check that the trace cache file is up to date, and then
17926 compare its timestamp with that of the output.
17928 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
17929 the preamble. Don't require 5.005 as Autom4te::General does it,
17930 and better yet (use `use', not `require'!).
17931 * lib/Autom4te/Struct.pm: Rename the last occurrences of
17932 Class::Struct as Autom4te::Struct.
17933 * lib/Autom4te/General.pm (File::stat): Use it.
17934 (&mtime): New, export it.
17935 * bin/autom4te.in: Use it.
17936 Declare `$req' is invalid if it is outdated.
17937 Don't declare it valid before saving it if something went wrong.

17942 must be proposed to the users.
17944 * bin/autom4te.in (@required_trace): Remove.
17946 (&parse_args, &print_usage): -p, --preselect is a new option.

17987 (m4_divert_pop): Dump the whole diversion stack when a diversion
17989 * bin/autom4te.in (&handle_output): Remember of the first
17990 occurrence of a possibly undefined macro, not the last.
17991 Complain about the possibly undefined macros in the same order as
17992 the appear in the output.
17993 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
17994 * tests/tools.at (autoconf: forbidden tokens, basic)
17995 (autoconf: forbidden tokens, exceptions): No longer sort
17996 autoconf's stderr, as it is now deterministic.
17997 Check that `dnl' is caught.

18019 `END', as `Autom4te::General::END' will be triggered.
18020 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
18021 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
