2584 Cover more potentially problemtic file names. Use the new
2587 Properly handle funny file names for headers in config.status.
2588 The test suite did not cover this bug because the code was not
2589 quoting properly the arguments of `rm -f' (which "fails" silently)
2590 as well as the arguments of `diff' (whose output was redirected to
2591 /dev/null so we couldn't see its error message).

2706 Add 'testsuite -C dir'.
2707 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
2709 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
2711 <DEFAULTS>: Delay computation of variables based on $at_dir...
2712 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
2713 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
2714 <PARSE_ARGS>: Parse new option.
2715 <HELP_TUNING>: Document it.

2731 * doc/autoconf.texi (Particular Programs): Do not mention the
2732 Autoconf version in which the AC_PROG_INSTALL change was done.

2737 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
2738 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
2739 mode, we change to the source directory, also set $ac_pwd so we
2740 do not go back to the build tree for the next config subdir.
2741 * tests/torture.at (Deep Package): Extend test to contain two
2742 config subdirs on the top level.
2744 Fix parallel `maintainer-check'.

2773 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2775 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
2776 check_SCRIPTS. Building the wrappers for `all' allows help2man

2796 (m4_require): Use m4_do, not m4_join.
2798 Fix some whitespace tests on cygwin.
2799 * tests/tools.at (autom4te and whitespace in file names): Restore
2800 font-lock. Create $TMPDIR before it might be used.

2803 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
2805 Optimize AC_REQUIRE.

2818 * tests/base.at (Input/Output): Likewise.
2819 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
2820 config.guess, and config.sub to test source tree.

2824 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
2825 (Substitute a newline, datarootdir workaround): Likewise.
2826 (Define a newline): Adjust for linenumber changes in configure.ac.

2836 * tests/m4sh.at (LINENO): Quote $0.
2838 Fix testsuite program wrapper for whitespace in `pwd`.
2839 The problem here is that the usual mantra is that command
2840 variables can contain arguments, thus we cannot just escape
2841 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
2842 $top_builddir/tests directory early in $PATH, so that the
2843 wrappers are found by their plain name.
2844 * tests/wrapper.as: Put $testdir early in $PATH.

2857 <at_func_create_debugging_script, Driver Loop>:
2858 Quote $at_group_dir.
2859 * tests/autotest.at (whitespace in absolute testdir): New test.
2861 * lib/autom4te.in: Quote @datadir@.
2863 Proper file name escaping in Autoconf programs and Perl modules.
2864 This includes escaping of characters special to the shell
2865 as well as special to Perl, e.g., leading `<' or `>'.
2866 For example, when $file starts with `>', `open ">$file"'
2867 wrongly tries to append to a different file.
2868 * bin/autoconf.as: Fix quoting for autom4te options.
2869 * lib/Autom4te/General.pm (shell_quote): New function, taken
2870 from coreutils, written by Jim Meyering.

2878 * bin/ifnames.in: Likewise, XFile usage fixes.
2879 * tests/tools.at (autom4te and whitespace in file names): Extend
2880 test. Test twice, with special characters allowed on w32, and the
2881 rest. Test leading and trailing whitespace, for `open_quote'.
2882 (autotools and whitespace in file names): New, analogous test.
2883 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
2884 by Russ Allbery and Eric Blake.

2888 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
2889 * lib/Autom4te/FileUtils.pm (open_quote): New function.
2890 (update_file, contents): Use it.
2892 * Makefile.am (autom4te-update): Rewrite for git.
2894 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2896 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
2898 Fix copyright years.
2899 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
2900 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.

2910 * doc/Makefile.am (TEXINFO_TEX): Add.
2912 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
2914 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
2915 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
2916 #undef as this runs afoul of our new way of creating config.h.
2917 Problem reported by Jim Meyering in
2918 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

2923 * bin/autom4te.in (files_to_options): Quote active characters

2934 `#AT_STOP_...' line at the end of each test.
2936 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2938 * lib/autotest/general.m4 (AT_INIT): For awk line number
2939 extraction script, ensure `$at_group' has a defined value
2940 even for the empty set, and properly quote its usage inside
2943 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2945 * doc/autoconf.texi (Shell Functions): New chapter. Document
2946 IRIX sh $0 issue in functions, move content from ...
2947 (Portable Shell): ... here.
2948 (Shell Script Compiler): Note that shell functions are not
2949 totally unportable any more.
2951 2007-11-22 Stepan Kasal <kasal@ucw.cz>
2952 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2954 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
2955 extracting the line numbers of the last needed test.
2957 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2959 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2962 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2964 Fix IRIX testsuite debugging failures: $0 in functions.
2965 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2966 Do not use $0 inside a function, as IRIX sh will set that to the
2967 function name rather than the script invocation name.
2969 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
2970 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2972 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
2973 to extract test scripts.
2974 (AT_INIT): Extract and cache test script line numbers.
2976 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2978 * lib/autotest/general.m4: Revert 2007-11-15 patch and
2979 subsequent fixups; the awk -> here-document conversion trashes
2980 performance too much with AIX sh.
2982 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2984 * tests/local.at: Do not test m4, perl with AT_TESTED.
2986 Diagnose and guard against write errors dealing with config.status.
2987 The general idea is this: all write failures from `configure'
2988 writing `config.status' are indicated by $ac_write_error, which
2989 is only checked at the end. This is safe because config.status
2990 code is not executed before the file is complete. Other write
2991 failures, be they inside config.status, or in sub shell/awk
2992 scripts spawned from configure or config.status, typically need
2993 earlier checking, as their results are used right afterwards.
2994 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
2995 before writing config.status, check afterwards.
2996 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
2997 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
2998 Set `ac_write_error' for write failures to config.status. Barf
2999 upon write failures to temporary files.
3000 Adjust note about closing and reopening the here-document.
3001 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
3002 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
3003 reopening the here-document.
3004 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3005 Ensure `ac_write_error' does not escape into config.status.
3006 Also, add a couple of code paths not yet exercised in the test
3007 suite: a config file with input from stdin, and a config header
3009 Suggestion for catching write errors by Bruno Haible.
3011 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3013 Avoid error with Tru64 awk and testsuite lines with many words.
3014 * lib/autotest/general.m4 (AT_INIT): In the awk script that
3015 reads the testsuite, set the field separator to an unusual value,
3016 in order to not run over the limit of 199 fields. Tru64 4.0D awk
3017 even splits the input if $i, i>0, was never accessed in the script.
3019 Revert 2007-10-17 change.
3020 * TODO: Multiline args in config files and headers mean something
3021 different and are not fixed, see
3022 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
3023 Report by Stepan Kasal.
3025 * doc/autoconf.texi (Generic Programs): Fix typo.
3027 2007-11-16 Stepan Kasal <kasal@ucw.cz>
3029 AC_*_TOOL does not canonicalize the prefix
3030 * doc/autoconf.texi (Generic Programs): Do not say that
3031 the *_TOOL macros canonicalize, they simply use the `host_alias'.
3033 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3035 Diagnose write errors in config.status instantiations.
3036 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
3037 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
3039 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3040 Extend test to also check for some write error failures, using...
3041 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
3042 Report by Bruno Haible.
3045 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
3047 (_AT_CHECK): Use less indentation, to save space.
3049 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3051 Add witness macro for @top_build_prefix@ substitution.
3052 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
3053 (_AC_OUTPUT_FILE): Mention it here.
3055 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
3056 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3058 * lib/autotest/general.m4 (at_func_test): Remove.
3059 (AT_INIT): Pre-extract test groups into separate files.
3060 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
3061 Remove at-test-source files together with the $at_group_dir.
3062 * tests/autotest.at (Long test source lines): New test.
3064 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3066 Shell functions and variables may share a namespace.
3067 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
3070 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
3072 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
3075 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3077 * lib/autoconf/status.m4: Fix a couple of comment typos.
3079 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
3081 2007-11-13 Jim Meyering <meyering@redhat.com>
3083 Clean up the rule to create "expr".
3084 * tests/Makefile.am (expr): Don't redirect directly to target.
3085 Redirect just once, not for each echo statement.
3086 Use $@, not literal "expr".
3088 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
3090 Don't worry about preprocessor when testing long long.
3091 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
3092 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
3093 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
3094 These no longer check for preprocessor flaws.
3095 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
3096 Do not check for preprocessor flaws.
3098 2007-11-13 Jim Meyering <meyering@redhat.com>
3100 Adapt dependencies, now that a version change doesn't modify configure.ac
3101 * GNUmakefile: Remove "make clean" kludge.
3102 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
3104 Don't redirect directly to target.
3105 Use $@, not literal "version.m4".
3107 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3109 * doc/autoconf.texi (Making testsuite Scripts): Document
3110 ":;{" shorthand as in previous patch.
3112 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
3114 * doc/autoconf.texi (Limitations of Builtins): Document problem
3115 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
3117 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
3118 Use ":;{" shorthand.
3119 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
3121 2007-11-12 Jim Meyering <meyering@redhat.com>
3123 Add more non-srcdir build support.
3124 * GNUmakefile (dummy): Split a long line.
3125 Add -v option to autoreconf invocation.
3127 Remove the autoreconf-provided INSTALL, so that we regenerate it.
3128 * GNUmakefile (dummy): Remove INSTALL.
3130 Remove racy commands to build scripts in bin/ and tests/.
3131 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
3132 are guaranteed to be built, remove the rules that tried to build
3133 them. Before, with a parallel build, these rules could lead to
3134 two processes writing tests/wrapper.in concurrently.
3136 Build in man/ only *after* building in bin/ and tests/.
3137 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
3138 in both bin/ and tests/.
3140 Accommodate non-srcdir build-from-checkout.
3141 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
3142 Use git's --git-dir=$srcdir/.git option.
3143 Add quotes, in case tarball_version_file contains shell meta-characters.
3144 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
3145 * configure.ac: Pass "." to git-version-gen.
3147 Avoid spurious test failures due to version skew.
3148 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
3150 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3152 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
3153 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
3154 Remove conftest.dSYM directory.
3155 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
3156 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
3157 Remove `conftest.*' recursively.
3158 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
3159 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3161 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
3163 Report and analysis by Jeff Squyres and Peter O'Gorman.
3165 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
3167 Fix typos in variable names.
3168 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
3170 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
3172 Document that $((expression)) is not portable.
3173 * doc/autoconf.texi (Shell Substitutions): Here.
3175 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3177 Ignore configure --help* errors due to LINENO-impaired shells.
3178 * tests/torture.at (Configuring subdirectories, Deep Package):
3179 In the --help* tests in read-only trees, make `.' temporarily
3180 writable again for the `stderr' file, and ignore errors due to
3181 the attempt to write configure.lineno.
3182 Report by Patrick Welche.
3184 2007-11-10 Jim Meyering <meyering@redhat.com>
3186 Generate package.m4 in build-dir, not srcdir.
3187 * tests/Makefile.am (package.m4): Adjust target.
3188 Don't redirect directly to $@.
3189 (CLEANFILES): Add package.m4.
3190 ($(TESTSUITE)): Depend on just-built package.m4, not the one
3192 When running $(AUTOTEST), search "." before searching $(srcdir).
3194 Avoid a race condition that would make parallel "distclean" fail.
3195 * tests/Makefile.am (distclean-generic): Replace the default,
3196 automake-provided rule with an identical one, but with an additional
3197 dependency on distclean-local. Simply adding the dependency would
3198 cause automake not to emit the rule at all.
3199 * BUGS: Building with -jN works, now.
3201 Distribute git-version-gen.
3202 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
3203 since GNUmakefile is distributed, and requires it for dist* rules.
3205 Remove two more generated files from version control.
3206 * INSTALL: Remove generated file.
3207 * lib/autoscan/autoscan.list: Remove generated file.
3209 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
3211 * GNUmakefile (PATH): Remove stray apostrophes; they become
3212 part of PATH, which isn't wanted here.
3214 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3216 New config files output variable `top_build_prefix'.
3217 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
3219 * doc/autoconf.texi (Preset Output Variables): Document it.
3221 Report by Bob Friesenhahn.
3223 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
3224 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
3225 function, to parametrize arithmetic with expr vs. the shell.
3226 Use it where possible.
3227 Suggestion by Benoit Sigoure.
3229 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
3231 Adjust the documentation of autotest WRT atlocal.
3232 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
3233 when using Automake, to write a rule to produce atlocal, since it's
3234 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
3235 distributed, not atconfig.in.
3237 2007-11-04 Eric Blake <ebb9@byu.net>
3239 Update list information.
3240 * README: Mention new autoconf-commit list.
3241 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
3243 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3245 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
3247 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
3249 * build-aux/.gitignore: Ignore mkinstalldirs.
3251 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
3253 2007-11-03 Jim Meyering <meyering@redhat.com>
3255 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
3256 * build-aux/git-version-gen: This syncs from coreutils.
3258 Adjust the build procedure so "make check" works reliably.
3259 * README-hacking: Include an extra step between "make" and
3260 "make check" to ensure that the latter passes.
3262 Use just-built tools, when possible.
3263 * GNUmakefile (PATH): Set and export here, ...
3264 (dummy): ... rather than here.
3266 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3267 and Andreas Schwab <schwab@suse.de>
3269 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
3272 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3274 * configure.ac (AC_PREREQ): Require version 2.60, for
3275 AC_PROG_SED, AC_PROG_GREP.
3277 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
3278 and Jim Meyering <meyering@redhat.com>
3279 and Andreas Schwab <schwab@suse.de>
3280 and Eric Blake <ebb9@byu.net>
3282 Document a bug in GNU Bash with compound commands and redirections.
3283 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
3284 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
3287 2007-11-03 Eric Blake <ebb9@byu.net>
3289 Support m4 1.4.5 in testsuite.
3290 * tests/torture.at (Define a newline): Exclude line numbers in
3292 Reported by Ralf Wildenhues.
3294 2007-11-03 Jim Meyering <meyering@redhat.com>
3296 Remove automake-provided files from version control.
3297 * build-aux/elisp-comp: Remove file.
3298 * build-aux/install-sh: Remove file.
3299 * build-aux/missing: Remove file.
3300 * build-aux/mdate-sh: Remove file.
3301 * build-aux/.gitignore: New file.
3302 Suggestion from Ralf Wildenhues.
3304 2007-11-03 Eric Blake <ebb9@byu.net>
3306 Adjust version comparison to account for git snapshot numbers.
3307 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
3308 component separator.
3309 * doc/autoconf.texi (Number processing Macros)
3310 <m4_version_compare>: Document this change.
3311 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
3313 2007-10-30 Bruno Haible <bruno@clisp.org>
3315 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
3316 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
3317 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
3318 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
3319 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
3320 Suggested by Paul Eggert.
3322 2007-10-28 Jim Meyering <meyering@redhat.com>
3324 * README-hacking: Autoconf, Automake, and Perl are required to build.
3325 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
3327 2007-10-28 Jim Meyering <meyering@redhat.com>
3329 README-hacking: Recommend running autoreconf -vi.
3330 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
3331 so that we use just-built tools when they're available.
3332 Suggestions from Ralf Wildenhues.
3334 2007-10-28 Jim Meyering <meyering@redhat.com>
3336 Make inter-release --version output more useful.
3338 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
3339 which indicates that it is built using the 19th change set
3340 (in _some_ repository) following the "v2.61a" tag, and that 58dd
3341 is a prefix of the commit SHA1.
3342 * build-aux/git-version-gen: New file.
3343 * configure.ac: Run it to set the version.
3344 (AM_INIT_AUTOMAKE): Don't check NEWS here.
3345 * Makefile.am (dist-hook): Arrange so that .version appears only
3346 in distribution tarballs, never in a checked-out repository.
3347 * .gitignore: Add .version here, too. Just in case.
3348 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
3349 not configure.ac, now that the version number changes automatically.
3351 Ensure that $(VERSION) is up to date for dist-related targets.
3352 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
3353 git-version-gen doesn't match $(VERSION), but only for dist targets.
3355 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3357 Fix `Deep Package' failure with a configure script early in PATH

3359 Report by Jim Meyering.
3361 2007-10-27 Jim Meyering <meyering@redhat.com>
3363 Remove all generated files from version control.
3364 * aclocal.m4: Remove.
3365 * configure: Remove.
3366 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
3367 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
3368 * README-hacking: New file: how to build from just-checked-out sources.
3370 2007-10-23 Eric Blake <ebb9@byu.net>
3372 Improve corner case of m4_expand.
3373 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more
3375 * tests/m4sh.at (AS@&t@_HELP_STRING): Test overquoted comma.
3376 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
3379 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>

3387 problem reported by Bruno Haible in
3388 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
3390 2007-10-22 Eric Blake <ebb9@byu.net>
3392 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
3395 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
3397 Don't check for bug in HP-UX 11.00 cpp.
3398 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
3399 Use -1ull rather than -1u, since that causes problems with gnulib; see
3400 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

3410 2007-10-21 Eric Blake <ebb9@byu.net>
3412 * configure: Regenerate.
3414 2007-10-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3416 Fix config status generation with Tru64 ksh.
3417 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix
3418 escaping of backslash in here-documents.
3420 Fix `Deep Package' test failure on FreeBSD.
3421 * tests/torture.at (Deep Package): Do not add `.' to $PATH
3422 unnecessarily. Do not try running `/bin/sh configure' with a
3423 configure script to be found in $PATH, if the shell does not do
3424 this resolution. Fixes test failure on FreeBSD.
3426 Fix config header generation with AIX awk.
3427 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
3428 script, use helper array D_is_set, as `" 0"' does not evaluate

4504 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp

4609 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
4610 for a.* when searching for executables, as this prevents users

4624 AC_CHECK_TYPE, AC_CHECK_TYPES.
4625 * doc/autoconf.texi (Generic types): C types must be type-names
4626 (the C terminology), not type-ids (the C++ term). C++ types
4627 must not be anonymous.
4628 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
4629 for C++; this drops support for anonymous struct and union types,
4630 which were problematic anyway.
4631 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
4634 2007-04-12 Jim Meyering <jim@meyering.net>

4649 with objects too. Document the restrictions on its use.
4650 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
4651 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
4652 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
4653 works but the latter doesn't, then it's a valid type.
4654 This lets people use function types and so forth.
4655 For C++ there doesn't seem to be a simple solution, so leave it alone.
4656 (AC_CHECK_SIZEOF): Allow argument to be a variable.
4657 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
4658 AC_CHECK_TYPE; that wasn't documented or necessary.

4706 checks for unsigned long long int.

4710 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
4711 nonstandard grep R.E. escape sequences.
4713 2007-03-17 Jim Meyering <jim@meyering.net>
4715 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
4716 (Limitations of Usual Tools): Also list \< and \>, and mention that
4717 HP-UX's grep, like the one from Solaris, does not support that syntax.
4719 2007-03-09 Stepan Kasal <kasal@ucw.cz>
4721 * doc/autoconf.texi (Specifying Names): `--host' does not
4722 change the build type.

4828 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
4829 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
4830 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
4831 substitution will still be done by the special code.
4832 Report by Jim Meyering.
4834 * doc/autoconf.texi (File System Conventions): Mention that
4835 $PATH_SEPARATOR is for the build system only.

4913 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
4915 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
4916 preprocessor macro arguments in traced name.
4917 * doc/autoconf.texi (Defining symbols): Document longstanding
4918 support for AC_DEFINE-ing macros with arguments, and document
4919 behavior when the same variable has multiple AC_DEFINEs.
4920 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
4921 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
4922 macros directly, giving much shorter and simpler code.
4924 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
4926 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
4927 space before "$ac_configure_args" to prevent a 'config.status
4928 --recheck' failure if ac_configure_args doesn't contain a leading
4929 space. This works around a problem with the XEmacs configure.ac,
4930 which uses the (undocumented) ac_configure_args variable
4931 inconsistently with Autoconf.
4933 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
4935 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
4936 Include <limits.h>, and use its INT_MAX to rewrite the
4937 j loop so that it does not overflow 'int'. Problem reported by
4939 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
4940 Play it safe by shifting left by 1 rather than multiplying by 2,
4941 as GCC is less likely to optimize this away when the value
4942 is signed (when it assumes overflow leads to undefined behavior).
4943 Also, don't assume time_t uses two's complement.
4945 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4947 * tests/torture.at (Substitute a 2000-byte string): Avoid using
4948 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
4949 dumps core on it. Report by Tim Rice.
4951 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4953 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
4954 --disable-option-checking to --help output even when
4955 AC_PRESERVE_HELP_ORDER is not used.
4956 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
4957 --with argument, rather than argument with [-.] replaced by
4959 * NEWS: Fix typo in previous change; the news was in the
4962 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4964 * NEWS: Warnings are now generated by default for unknown
4965 --enable-* and --with-* options.
4966 * doc/autoconf.texi (Option Checking): Renamed from
4967 (Configure Option Checking). Tighten up the wording a bit.
4968 (External Software, Package Options): Cross-reference to Option
4969 Checking, and use this to shorten our section.
4970 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
4971 "$x" to test "x$foo" != x.
4972 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
4973 Don't warn if $enable_option_checking is "no".
4974 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
4975 ac_unrecognized_opts to the empty string.
4976 Don't echo the unrecognized opts, as this might mishandle
4977 backslashes or leading -.
4978 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
4979 usage next to the other --disable-FEATURE options in the
4982 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4984 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
4985 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
4986 Print warning for unrecognized --with and --enable options
4987 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
4988 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
4989 Disable option checking when subdirs are configured.
4990 (AC_OUTPUT): If warnings are enabled, print warning about
4991 unrecognized --with and --enable options at the end of
4992 the configure output (as well as at the beginning).
4993 * doc/autoconf.texi (Option Checking): New node.
4994 Document new option warning functionality.
4996 2006-12-16 Eric Blake <ebb9@byu.net>
4998 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
4999 * NEWS: Start news for current version.
5001 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
5003 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5004 Define HAVE_GETMNTENT to 1, not to the empty string.
5005 Problem originally reported by Jochen Friedrich in
5006 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
5008 This change prompted by a problem report by Andrey Simonenko in
5009 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
5010 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
5011 object-like macros only, in the traditional portable character
5013 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
5014 Warn about attempts to define things that are not identifiers.
5015 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
5016 awful hack that AC_DEFINEd macro names containing parentheses.
5018 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
5020 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
5021 too drastic, even if Texinfo in theory requires it for info mode.
5023 (config.status Invocation): Renamed back from Recreating a
5025 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
5026 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
5028 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
5030 * NEWS: Version 2.61a.
5032 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
5033 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5035 * NEWS: Document changes with echo and printf, and the lack
5036 of limits on the total size of multi-line values of substituted
5037 variables, and the AC_FUNC_FSEEKO fix.
5039 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
5041 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
5042 Writing configure.ac.
5043 (Autoconf Input Layout): Renamed from configure.ac Layout.
5044 (Recreating a Configuration): Renamed from config.status Invocation.
5045 (Obsolete Recreation): Renamed from Obsolete config.status Use.
5046 (acconfig Header): Renamed from acconfig.h.
5047 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
5048 (Writing Testsuites): Renamed from Writing testsuite.at.
5049 (Autom4te Cache): Renamed from autom4te.cache.
5051 * BUGS: Remove mention of VPATH problem, since it's now documented
5052 not to be a bug in the Autoconf build procedure itself, but rather
5053 a problem with the proprietary `make' programs.
5055 * doc/autoconf.texi (Build Directories): Add a cross reference
5058 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
5059 * doc/standards.texi: Sync from gnulib.
5061 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
5062 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
5063 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
5064 generated automatically.
5066 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
5068 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
5069 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
5070 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
5072 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5074 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
5075 `CEOF$ac_eof' special marker, the awk script cannot contain a
5076 line matching `^CEOF', so this is not needed any more.
5077 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
5078 special marker in the test.
5080 2006-12-06 Stepan Kasal <kasal@ucw.cz>
5082 * tests/tools.at (autom4te preselections): Use `find -newer';
5083 remove one of the sleeps.
5085 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
5086 more readable, using ...
5087 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
5089 * doc/autoconf.texi (autoheader Invocation): Do not double-
5090 quote the parameter of `AH_BOTTOM' in the example.
5092 2006-12-05 Stepan Kasal <kasal@ucw.cz>
5094 * doc/autoconf.texi (Configuration Headers): Remove the
5095 example with multiple input files.
5096 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
5097 multiple input files.
5099 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5101 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
5102 creating the awk substitution script, handle one input line at a
5103 time, so that the maximum length of a substituted (multi-line)
5104 value is not limited by the size of the sed pattern space.
5105 The trade-off is a slightly repetitive sed script.
5106 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
5107 can only have up to 7 characters, due to Solaris 10 /bin/sed.
5108 * tests/torture.at (Substitute a 2000-byte string): Increase the
5109 test with several long lines, they should not be caught by sed
5112 * tests/tools.at (autom4te preselections): New test, to flag
5113 entries missing from autom4te.cfg.
5114 Report by David Byron <dbyron@hheld.com>.
5116 * tests/torture.at (Substitute a 2000-byte string): Actually use
5117 AC_PROG_AWK, so the last change works as intended.
5118 (Substitute and define special characters): Likewise.
5119 (Substitute a newline): Likewise.
5121 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
5122 instead of `awk' consistently.
5123 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
5124 * tests/torture.at (Torturing config.status): Test both the
5125 result of AC_PROG_AWK and plain awk.
5126 (Substitute a 2000-byte string): Likewise.
5127 (Substitute and define special characters): Likewise.
5128 (Substitute a newline): Likewise.
5130 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
5132 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
5133 can be assigned to a function pointer. Problem reported by
5134 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
5135 part of a patch by Ralf Wildenhues in that same bug report.
5137 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
5139 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
5140 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
5142 2006-12-01 Eric Blake <ebb9@byu.net>
5144 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
5145 cross-compiling from cygwin to mingw.
5146 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
5147 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
5148 to lib/autoconf/c.m4.
5150 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5152 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
5153 string for more reliable failure. Wrap the entire test that
5154 causes the broken Solaris printf to dump core, in a subshell,
5155 so the segmentation fault message is reliably suppressed.
5156 Fix shell expansion errors by using /usr/ucb/echo always;
5157 avoid an error on systems without it by another subshell.
5158 Avoid m4 expansion of `$1'. Set the zeroth argument of the
5159 subshell-$as_echo to `as_echo', for better error message.
5161 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5163 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
5164 `BASH_SOURCE' contain a newline, set them to empty, as they may
5167 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
5169 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
5170 years and is too hard to maintain now. The last straw was
5171 reported by Jerker Baeck in
5172 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
5173 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
5174 * doc/autoconf.texi (Particular Functions): Move
5175 AC_FUNC_SETVBUF_REVERSED from here...
5176 (Obsolete Macros): ... to here. Say that it does nothing now.
5177 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
5178 Turn into (almost) a no-op.
5180 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
5182 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
5183 These macros are obsolescent and new applications shouldn't need them.
5184 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
5185 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
5186 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
5187 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
5188 (AC_FUNC_VPRINTF): Likewise.
5189 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
5190 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
5191 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
5193 * doc/autoconf.texi (Setting Output Variables): Mention that
5194 @VAR1@VAR2 has unspecified behavior. Problem reported by
5196 * NEWS: Mention this.
5198 * Makefile.am: Put only a single '#' into the copyright notice,
5199 so that it's also present in the output file. Standardize wording
5200 in makefile copyright notices to match GNU coding standards.
5201 * bin/Makefile.am: Likewise.
5202 * doc/Makefile.am: Likewise.
5203 * lib/Makefile.am: Likewise.
5204 * lib/freeze.mk: Likewise.

5209 * man/Makefile.am: Likewise.
5210 * tests/Makefile.am: Likewise.
5211 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
5214 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5216 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
5217 in the sed script that mangles the awk script: delete up to the
5218 first exclamation mark only.
5219 * tests/torture.at (Substitute and define special characters):
5222 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5224 Rewrite config files generation: avoid quadratic growth in
5225 the number of substituted variables by using awk instead of sed
5226 for the bulk of the substitutions.
5227 * NEWS: Mention this.
5228 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
5229 forbidden in the output (and thus input) file.
5230 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
5231 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
5232 generate just one large awk script for substitutions,
5233 eliminating much of the earlier complexity, while adding some
5234 new complexity. Only expand the substitution templates at
5235 configure time, for smaller configure script size. If
5236 _AC_SUBST_FILES are used, test 'awk' for working getline support
5237 at config.status time. If absent, interpolate through the
5238 shell. The awk script was written with much help
5239 from Paolo Bonzini and Paul Eggert.
5240 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
5241 (_AC_SED_FRAG_NUM): Likewise.
5242 (_AC_SUBST_CMDS): Renamed from...
5243 (_AC_SED_CMDS): ...this.
5244 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
5245 * tests/torture.at (Substitute a 2000-byte string): Also
5246 substitute a line with 1000 words, and a variable with several
5248 (Substitute and define special characters): Test awk special
5249 characters, and put substitution input strings `@foo@' in the
5250 output, to test that no recursion happens; test several other
5251 combinations from Paolo Bonzini.
5253 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
5255 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
5256 that replaced echo with AS_ECHO where this wasn't necessary.
5257 Problem reportd by Ralf Wildenhues.
5258 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
5259 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
5260 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
5262 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5264 * lib/freeze.mk (GREP): Removed, no need to initialize this.
5266 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
5268 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
5269 that traditional Awk lacks 3-arg "split". It has it.
5270 Mention that FS must be a single character, and a few other
5271 99-byte limits of traditional Awk.
5272 Mention that if (i in a) doesn't work with traditional Awk.
5274 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
5276 * tests/autotest.at (BSx641-newline in command):
5277 (BS-BS-newline in command, BSx640-newline in command):
5278 (Newline-CODE-BS-newline in command):
5279 (Single-quote-BS-newline in command):
5280 (Single-quote-newline-BS-newline in command):
5281 Use printf '%s\n' instead of echo, for portability to hosts
5282 where echo interprets backslashes. This will break on hosts
5283 that lack printf, but for now let's assume all such hosts
5284 are dead (if not, we should get reports of test failures).
5286 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
5288 'echo' has some portability problems, when given a first argument
5289 with a leading '-', or when given any argument containing '\'.
5290 Avoid using 'echo' in these cases.
5291 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
5292 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
5293 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5294 * lib/autotest/general.m4 (AT_INIT): Likewise.
5295 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
5296 argument might be unportable.
5297 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
5298 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

5302 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
5303 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
5304 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.

5314 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
5315 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
5316 * bin/autoconf.as: Redo verbose flag implementation, as the old
5317 scheme wouldn't work with AS_ECHO.
5318 * lib/autotest/general.m4 (AT_INIT): Likewise.
5319 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
5320 Don't use ECHO_T, since ECHO_N is now reliable.
5321 * lib/autotest/general.m4 (AT_INIT): Likewise.
5322 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
5323 rather than using a here-document to put the script into a file.
5324 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
5326 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
5327 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
5328 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
5329 bug, but we might as well stop using ECHO_N and ECHO_C internally.
5330 * lib/autotest/general.m4 (AT_SETUP): Likewise.
5331 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
5332 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5333 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
5334 operand, as AS_ECHO requires. Avoid double file name expansion.
5335 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
5336 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
5337 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
5338 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.

5442 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
5445 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
5447 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
5448 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.

5475 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.

5480 Single-quote in a test title,
5481 Double-quote in a test title): Don't expect failure anymore.
5482 (Backslash in a test title): Put a non-whitespace character after the
5483 backslash so that Bourne shells might actually see it as an escape
5485 (Brackets in a test title,
5486 Pound in a test title,
5487 Comma in a test title,
5488 Quoted Macro in a test title,

5492 Macro with double-quote in a test title,
5493 Macro with backslash in a test title): New tests expected to fail.
5494 * tests/torture.at (#define header templates): M4-quote this title in
5495 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
5496 The visible effect was a stray [] in the testsuite output.
5498 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5500 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
5501 `trap ... 0' inside a function, for AIX sh.
5503 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
5505 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
5506 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
5507 5363) simply issues a warning when dividing by zero at compile
5508 time. Problem reported by Elias Pipping.
5510 2006-10-26 Eric Blake <ebb9@byu.net>
5513 * doc/autoconf.texi (Evaluation Macros): Improve the example to
5514 show effect on macros that expand with commas.

5539 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
5541 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
5542 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
5543 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
5544 reported by Nelson H. F. Beebe for Coreutils 6.4.
5546 * tests/tools.at (autoconf --trace: user macros): Remove test
5547 for tracing multiline macros, since m4 1.4.7a uses a different
5548 way to number lines. Problem reported by Ralf Wildenhues.
5550 2006-10-24 Stepan Kasal <kasal@ucw.cz>

5575 * doc/autoconf.texi (Caching Results): Likewise.
5576 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
5577 AC_CACHE_CHECK_INT, since it's no longer public.
5578 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
5579 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

5610 looking for special shell characters.
5611 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
5612 macro defined by AS_VAR_PUSHDEF before passing it as a

5624 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
5626 (Imported from Automake.)
5627 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
5628 which incorrectly sets the mode of an existing destination
5629 directory. In some cases the unpatched install-sh could do the
5630 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
5631 system. We hope this is rare in practice, but it's clearly worth
5632 fixing. Problem reported by Alex Unleashed in
5633 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
5634 Also, don't bother to check for -m bugs unless we're using -m;
5635 suggested by Stepan Kasal.

5643 is enabled by default with gnu and gnits strictness.
5644 Report from Bruno Haible.
5646 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

5655 Import this change from Gnulib:
5657 2006-09-16 Karl Berry <karl@gnu.org>
5658 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
5659 to avoid sectioning errors.
5661 Import these changes from Texinfo:
5663 2006-10-04 Karl Berry <karl@gnu.org>
5664 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

5672 * build-aux/texinfo.tex (\textdegree): New command.
5674 2006-08-12 Karl Berry <karl@gnu.org>

5679 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
5681 2006-10-13 Stepan Kasal <kasal@ucw.cz>
5683 * doc/autoconf.texi (Autoheader Macros): Warn that the text
5684 added to the template can get mangled.
5686 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5688 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
5689 include the default headers, and redefine obstack_chunk_alloc
5690 and obstack_chunk_free. Fixes false failure with glibc.
5692 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
5694 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

5707 the NonStop platform.
5708 * doc/autoconf.texi (Posix Variants): Likewise.
5709 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
5711 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
5712 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
5713 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
5714 Use a better substitute, by inspecting the output of "ls"
5715 rather than just using ":".
5716 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
5717 rather than AS_EXECUTABLE_P, since we needn't worry about
5718 non-regular files here.
5720 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
5721 due to configuration hassles with this. See Tonya Underwood's report
5722 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

5733 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
5734 initialization which is not inherited through the environment
5735 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
5736 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

5741 problems with mkdir -p -m.

5745 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
5746 comment about ac_cpp_err; it was incorrect, and anyway
5747 ac_cpp_err is being removed below.
5748 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
5749 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
5750 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
5752 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
5753 with werror_flag and conftest.err and so forth. This is more
5754 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
5755 and anyway the user shouldn't normally want to see this gorp logged.
5756 Problem reported by Ralf Wildenhues.
5757 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
5758 empty, not 'no', since the rest of the code uses 'test -z'.
5760 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
5762 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5763 Use a single call to AC_DO_TOKENS rather than multiple, for
5765 (_AC_LINK_IFELSE): Test that resulting file is executable.
5766 Problem reported by mwoehlke in
5767 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
5769 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
5770 than creating a file to use with test -x; this is much faster.
5772 2006-10-02 Bruno Haible <bruno@clisp.org>
5774 * lib/autom4te.in (Automake-preselections): Add
5775 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
5777 2006-09-27 Stepan Kasal <kasal@ucw.cz>
5779 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
5780 standard error, `experr' should be used, not `expout'.
5782 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
5784 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
5785 fseeko testing program twice; just use the earlier result.
5786 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
5787 Set cache var to 'unknown' (not 'no') if leaving the macro unset
5788 still doesn't let the program compile.
5789 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
5792 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
5793 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
5794 include it, without including anything else.
5795 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
5797 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
5799 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5801 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
5802 `error.h', and include it, for a `error_at_line' prototype.
5803 Use a nonempty format string in the link test.
5804 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
5805 for a declaration of wait3.

5811 can apply to constants too, and that it checks for macro defns.
5812 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
5813 and simply cast the identifier to void. This handles structure
5814 values. Problem reported by Ralf Wildenhues.

6289 Require that long long int be at least 64 bits wide. C99 requires
6290 this and enough programs depend on it so we should check for it.
6291 Bruno Haible reports in
6292 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
6293 that long long int is 32 bits wide with some nonstandard compilers.
6294 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
6296 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
6298 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
6299 to a nonexistent file, so that we don't have to worry about
6300 a local site configuration that doesn't use /usr/local.
6301 Problem reported by Keith Marshall in
6302 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
6304 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
6306 * doc/autoconf.texi: Be more consistent about using @acronym with
6307 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
6308 quite right (it talked about "OSF/Tru64", even though the
6309 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
6310 and it even mentioned "OSF 4"!) and at this point there's little
6311 reason to talk about OSF any more, since it died in 1994.
6312 (Specific Compiler Characteristics): Simplify example of
6313 negative-size array.
6314 (File Descriptors): Reorder to make the text flow better.
6315 Remove joke about "appreciate the various levels"; I didn't get it.
6316 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
6317 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
6318 (File Descriptors, Limitations of Usual Tools):
6319 Tone down the advice against renaming or removing open files.
6320 (Limitations of Usual Tools): Add a new section, on 'rm'.
6322 2006-06-26 Stepan Kasal <kasal@ucw.cz>
6324 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
6325 -lXt in LIBS, idea from Karsten Hopp; this was due since
6328 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
6329 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
6330 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
6331 (which belong to Xt, not X itself). See Debian bug 327655.
6333 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6335 * configure.ac (AC_INIT): Bump to 2.60a.
6338 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6342 * configure.ac, NEWS: Update.
6344 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6346 * config/texinfo.tex: Sync from upstream.
6348 * bin/autom4te.in (handle_traces): Transform the `@S|@'
6349 quadrigraph correctly in traces.
6351 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
6354 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
6355 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
6357 * doc/autoconf.texi (Changed Directory Variables): New node,
6358 to document the whole `datarootdir' business a bit better.
6360 * tests/torture.at (datarootdir workaround): Extend test.
6361 Prompted by report by Alexandre Julliard.
6363 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
6365 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
6366 when using default mode of IBM C 6 for AIX. Problem and two-line
6367 fix reported by Larry Jones.
6369 2006-06-22 Alexandre Julliard <julliard@winehq.org>
6371 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
6372 about literal '${datarootdir}' if a definition is found in the
6375 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
6377 * NEWS: Use "M4" rather than "m4" when appropriate.
6378 Problem reported by Eric Blake.
6379 * doc/autoconf.texi: Likewise.
6380 Use @acronym around BSD, GCC, and GNU when appropriate.
6381 (Why GNU M4): Renamed from "Why GNU m4".
6382 (Redefined M4 Macros): Mention that Posix
6383 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
6384 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
6387 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6389 * bin/autom4te.in (handle_output): Do not forbid the empty
6391 * tests/tools.at (autoconf: the empty token): New test.
6393 2006-06-20 Stepan Kasal <kasal@ucw.cz>
6395 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
6396 calls, so that we do not care whether they are LIFO or FIFO;
6397 in the m4_wrap, do not check which diversion is the topmost
6398 one, just check that the stack is balanced at the end.
6399 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
6400 base diversion forever--pop the previous diversion before
6401 opening the new one; consequently, remove the m4_wrap call.
6402 * lib/autotest/general.m4 (AT_INIT): Likewise.
6403 * tests/m4sugar.at: Do not use
6404 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
6406 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
6407 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6409 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
6410 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
6411 Rework example of m4wrap token-pasting trouble so that it doesn't
6412 care whether it's LIFO or FIFO.
6413 Fix some "contrary to"s that are awkward in English.
6415 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6417 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
6418 to `yes' instead of `int$1_t' if the type is found, for more
6419 consistent configure output (where $1 is the number of bits).
6420 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
6421 Suggested by Bruno Haible.
6423 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
6424 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
6425 with system headers. Report by Bruno Haible.
6427 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6429 * config/config.guess, config/config.sub: Sync from upstream.
6431 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
6432 in order to avoid picking up an older installed frozen m4sh.m4f.
6433 Besides an outdated shell startup, this could have been created
6434 by an earlier M4 version with incompatible frozen file format.
6436 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
6438 * README: Recommend m4 1.4.4 instead of 1.4.3..
6439 * doc/autoconf.texi: Likewise.
6440 (Special Chars in Names): Say that $(.FOO) is portable, as
6441 suggested by Stepan Kasal.
6442 (Installation Directory Variables, Build Directories):
6443 (Automatic Remaking, Subdirectories, Fortran Compiler):
6444 (Making testsuite Scripts, Defining Directories):
6445 Quote variable usages better.
6446 (Making testsuite Scripts): Add clean-local rule to makefile
6447 snippet, by Eric Blake.
6448 (Installation Directory Variables): Fix table item font.
6449 Reword slightly to clarify. Generalize advice about
6450 not using special characters to include all file-related
6451 vars, not just VPATH.
6452 (Special Chars in Variables): Warn about special characters in
6454 (Assignments): Clarify default-value example as suggested by
6456 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
6457 (Special Shell Variables): Note leading ./ or ../, as suggested
6459 (Limitations of Builtins): Under cd, warn about CDPATH.
6460 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
6463 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6465 * doc/autoconf.texi (Configuration Actions): Remove duplicate
6466 `@var', for texi2html.
6467 (Systemology): Some more word wrapping, for DVI output.
6468 (autom4te Invocation): The short option for `--melt' is `-M',
6471 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
6473 * doc/autoconf.texi: More formatting and English tweaks,
6474 many suggested by Ralf Wildenhues.
6475 Reword to avoid "@code{...}'s" and the like, since it's ugly
6476 with Emacs info mode. discontents -> woes.
6477 Put a few "will"s back. time stamp -> timestamp.
6478 side-effect -> side effect.
6480 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
6482 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
6483 Warn about $@ not persisting. Problem reported by Julien Danjou in
6484 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
6485 (Special Chars in Names): Renamed from Leading _ in Macro Names.
6486 Mention other special chars, too.
6488 2006-06-14 Eric Blake <ebb9@byu.net>
6490 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
6492 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
6494 * doc/autoconf.texi: Some systematic minor improvements, as
6495 follows. Use "makefile" when talking about makefiles
6496 generally (which might be named "makefile" or "Makefile" or even
6497 "foo.mk"), "Makefile" when talking about a specific makefile
6498 called "Makefile". This unclutters the text from weird quotes
6499 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
6500 values" rather than "@var{foo}s" and similar constructs containing
6501 "}s". Use "Make rules" rather than "Makefile rules". Minor
6502 English-language improvements. Change the prefix "sub-" to "sub"
6504 Put blank lines around examples more consistently.
6505 Avoid "rather" and "very" as intensifiers.
6506 Avoid "will" as an auxiliary.
6507 (Limitations of Make): Split this node into....
6508 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
6509 (Leading _ in Macro Names, Backslash-Newline-Newline):
6510 (Backslash-Newline Comments, Long Lines in Makefiles):
6511 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
6512 (obj/ and Make, make -k Status, VPATH and Make):
6513 (VPATH and Double-colon, $< in Explicit Rules):
6514 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
6515 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
6516 New nodes, resulting from splitup of Limitations of Make.
6517 All cross-references changed. Raise the top node from
6518 a section to a chapter, and all subnodes accordingly.
6519 Redo the introductory wording to match the new organization.
6520 (Installation Directory Variables): Use an example that is
6521 closer to what Autoconf actually does. Mention that VPATH's
6522 value should not contain metacharacters or white space.
6523 (Fortran Compiler): Fix a VPATH bug in an example.
6524 (Leading _ in Macro Names): Mention that this problem is no longer
6525 of practical concern.
6526 (VPATH and Make): Reword the advice to make it clearer
6527 that Autoconf and Automake support VPATH in non-GNU make, but
6528 many packages have bugs in this area.
6529 ($< in Explicit Rules): Refer to Build Directories rather
6530 than using a (non-VPATH-safe) example.
6531 (Automatic Rule Rewriting): Mention the sort of disaster that
6532 can ensue with Solaris-style rule rewriting with VPATH.
6534 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6536 * doc/install.texi (Compilers and Options): Weaken the
6537 suggestion to use GNU make for VPATH builds.
6539 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
6540 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
6542 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
6543 in regular expression.
6545 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6547 * doc/autoconf.texi (Installation Directory Variables):
6548 Drop extra @samp from `@table @samp' item.
6549 (Limitations of Usual Tools): Comment fix.
6550 Do not nest @samp just to point to other table items.
6551 (Writing testsuite.at) <AT_CHECK>: The second argument to
6552 `@dvar' is already @samp'ed.
6553 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
6554 do not use @var in the second argument.
6556 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
6558 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
6559 $as_shell.exe too. Problem reported by Andreas Buening in
6560 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
6562 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6564 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
6565 `unused variable' compiler warning, for `-Wall -Werror'.
6566 Reported by Jaap Haitsma in
6567 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
6569 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
6571 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
6572 case the compiler dumps core. Problem reported for
6573 OpenServer 5.0.7 by Tim Rice in
6574 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

6578 2006-06-06 Tim Rice <tim@multitalents.net>.
6580 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
6581 "ERROR" only shows up in "make check" output if there is an

6590 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
6592 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
6593 typically overflows on x86 CPUs, even though the C standard

6605 * config/texinfo.tex: Sync from upstream.
6607 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
6608 seen, invoke libtoolize with `--ltdl' argument.
6609 * lib/autom4te.in (Autoreconf-preselections): Adjust.
6611 Suggested by Eric Blake.
6613 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
6615 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem

6630 message issued by AC_REQUIRE.
6631 * tests/m4sugar.at: Check m4_require's error message.
6632 * tests/base.at: Check AC_REQUIRE's error message.
6633 * tests/local.at (AT_CHECK_M4): New macro, almost identical
6635 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
6637 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
6638 `expout' as the last parameter.
6639 * tests/tools.at: Adapt to the above change.
6641 2006-06-04 Stepan Kasal <kasal@ucw.cz>
6643 * doc/autoconf.texi (Limitations of Usual Tools): Correct
6644 information about race-free implementations of mkdir.

6653 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
6655 * NEWS: GNU make now recommended for VPATH builds.
6656 Mention that some macros are now documented to be obsolescent.
6657 * doc/autoconf.texi:
6658 Prefer "current" to "modern" to describe
6659 currently-used (albeit perhaps old-fashioned) hosts.
6660 Mention which ancient features no longer need to be worried about.
6661 setgid -> set-group-ID
6662 setuid -> set-user-ID (these are the Posix terms)
6663 Fix some misuses of "only".

6678 Omit longwinded and obsolescent discussion of cp -f.
6679 Modernize discussion of expr, ls.
6680 (Limitations of Make): Modernize discussion of VPATH builds.
6681 Mention $? as a workaround in some cases.
6682 * doc/install.texi (Basic Installation):
6683 Mention "./configure; make; make install" first. Be more
6684 specific about why this file is generic. Remove unnecessary
6685 parens. Remove misleading "only". Remove obsolete advice
6686 about csh. Don't say "configure" takes awhile; say it
6687 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
6688 and CC=c99 rather than CC=c89, as these are blessed by current
6689 Posix. Recommend GNU make if doing a VPATH build.
6691 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
6693 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for

6712 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
6714 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
6715 about quoting the case statement, just in case.

6733 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
6735 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
6736 about quoting ac_try: quote all of it, if any of it seems suspicious.
6737 This means we don't have to worry about ${ or sed any more.
6738 Also, double-quote the case statement, to work around misuses via
6739 underquoting as reported by Ralf Wildenhues in
6740 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.

6756 Problem reported by Ralf Wildenhues in
6757 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
6758 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
6759 pre-2006-05-26 definitions, but leave in the comments that
6760 these macros are dangerous and should not be used.
6761 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
6762 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
6763 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
6764 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
6765 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
6767 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
6769 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
6770 the use of 'tr', since this is our only use of 'tr'.
6772 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6773 and Paul Eggert <eggert@cs.ucla.edu>
6775 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
6776 Don't assume 'grep' works on long lines, since AIX grep doesn't.
6778 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6780 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
6781 the output file in the `${datarootdir}' test.
6783 2005-05-28 Stepan Kasal <kasal@ucw.cz>
6784 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6786 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
6787 mention of `datarootdir' in the input file(s), but literal
6788 `${datarootdir}' in the output file, and we haven't warned yet,
6789 then warn as well: the user may have (erroneously) used
6790 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
6791 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
6792 * tests/torture.at (datarootdir workaround): Extend this test.
6795 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6796 and Paul Eggert <eggert@cs.ucla.edu>
6798 * doc/autoconf.texi (autoheader Invocation): The first argument to
6799 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
6800 alternatives and clear up the language a bit.
6802 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
6804 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
6805 ac_config_guess, ac_config_sub, ac_configure.
6806 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
6807 Fix typo that prevented an unnecessary space from being removed.
6808 Problems reported by Ralf Wildenhues in:
6809 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
6811 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
6813 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
6814 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
6815 Don't use the term "thread-safe" to talk about mkdir race
6816 conditions, since the problem is more a process than a thread
6817 issue. Problem reported by Stepan Kasal in:
6818 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
6819 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
6820 the test for 'install' more closely. Look at MKDIR_P first.
6821 Look in the PATH, and at /opt/sfw/bin.
6822 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
6823 Don't bother to try mkdir -p, since we already check mkdir --version;
6824 just look at the version number. (There's no easy way to check
6825 for race-free implementations.)
6826 * tests/tools.at (autoconf: subdirectories): Adjust to above
6827 changes, since MKDIR_P now might end in "/mkdir -p".
6829 * doc/autoconf.texi (autoheader Invocation): Mention that the
6830 first arg of AC_DEFINE_UNQUOTED must be a literal.
6831 Problem reported by Ben Pfaff in
6832 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
6834 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
6835 * doc/autoconf.texi (Special Chars in Variables): New section.
6836 (Preset Output Variables): Warn about special chars in CPPFLAGS.
6837 (Installation Directory Variables): Quote $(datadir) better.
6838 (Limitations of Builtins): Describe some of eval's trickiness.
6840 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
6841 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
6842 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
6843 in front of every arg, not just trailing args. Quote apostrophes.
6844 (_AC_EVAL_ECHO): New macro.
6845 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
6846 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
6848 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
6849 exposed by quoting of eval argument. Put the command on line line
6851 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
6852 (_AC_PATH_X, AC_PATH_X): Quote more safely.
6853 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
6854 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
6855 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
6856 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
6857 Use eval more safely.
6858 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
6859 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
6861 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
6862 lines, exposed by quoting of eval argument.
6864 2006-05-26 Stepan Kasal <kasal@ucw.cz>
6865 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6867 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
6868 initialization of `ac_cv_exeext', do not override it if it was
6869 already set, unless it was set to `no', for compatibility with
6870 Autoconf-2.13, and comment this.
6871 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
6872 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
6873 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
6874 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
6875 Document that this test may be overridden by setting
6878 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6880 Revert these two patches:
6882 2006-04-06 Eric Blake <ebb9@byu.net>
6883 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6884 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6887 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6888 Clean up _AC_COMPILER_EXEEXT* macros.
6889 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6890 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6891 ac_file to the name of the default output file and call
6892 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6893 initial `rm' of the candidate files...
6894 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6895 the same list in subsequent `rm' calls, and for the temporary
6896 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6897 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6898 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6899 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6900 no longer needed) by libtool. Make it a cache check.
6901 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6902 copied here by mistake.
6903 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6904 _AC_COMPILER_EXEEXT.
6905 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6906 _AC_COMPILER_OBJEXT directly.
6907 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6909 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6911 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
6912 Fix description of how the buggy `sed' works.
6914 2006-05-25 Noah Misch <noah@cs.caltech.edu>
6918 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
6919 ENOLCK. Only mention `make -j' when applicable. Only raise
6920 fatal errors when `make -j' is involved. Improve error message.
6922 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6924 * doc/autoconf.texi (Here-Documents): We now know more about
6925 the variable expansion in here documents bug.
6926 Thanks to Tim Rice and Stepan Kasal.
6928 * doc/autoconf.texi (Making testsuite Scripts): Add an example
6929 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
6931 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6933 * tests/autotest.at (Multiline command from M4 expansion):
6934 No failure to be expected if the shell quotes newlines in
6935 commands in the `set -x' output. Report by Tim Rice.
6938 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6940 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
6941 expansion in the here-documents used by config.status, as that
6942 runs afoul of the Korn shell version M-12/28/93d bug described in
6943 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
6944 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
6945 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
6947 2006-05-23 Jim Meyering <jim@meyering.net>
6949 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
6950 Fix typo introduced with 2006-04-02 change. It reversed the sense
6953 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6955 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
6956 ac_dB slightly, to save bytes in the script.
6957 Max out at 50 lines, rather than 96; this is more likely
6958 (though not guaranteed) to avoid obscure 'sed' failures.
6960 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6962 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
6963 `tr -d -' as bad option argument. Work around this by deleting
6964 an unrelated character.
6965 Report by Tim Rice <tim@multitalents.net>.
6967 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
6968 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6969 Stepan Kasal <kasal@ucw.cz>
6971 * doc/autoconf.texi (Particular Programs): Do not promise that
6972 we always prefer the GNU version of the program, and that we
6973 search according to PATH; both rules can have exceptions.
6974 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
6975 AC_PROG_SED. Move descriptions of limitations
6976 to the Limitations of Usual Tools section.
6977 (Limitations of Usual Tools) <sed>: Mention script length
6978 limitations with Solaris /usr/ucb/sed.
6979 <grep>: Fix wording for empty alternative. Mention that -c and
6980 -l should not be combined, and that -E and -F should not be
6983 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6984 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6986 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
6987 limits in Solaris 8 /usr/ucb/sed by testing a long script.
6989 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6991 * doc/autoconf.texi (Defining Symbols): Literal parameter of
6992 AC_DEFINE is now passed to m4_pattern_allow.
6993 * NEWS: Mention that; likewise for AC_SUBST.
6994 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
6995 the parameter to m4_pattern_allow.
6996 * tests/tools.at: Add a check for that.
6998 2006-05-22 Stepan Kasal <kasal@ucw.cz>
7000 * lib/autoconf/status.m4: Fix typos.
7002 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7004 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
7005 only the files that this macro generates.
7007 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
7009 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
7010 the HP-UX sed limitation of 99 commands, labels do not count.
7011 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
7013 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
7015 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
7017 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
7018 Import the following fix from coreutils:
7020 2006-01-13 Jim Meyering <jim@meyering.net>
7022 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
7023 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
7024 not double-quote uses of that variable, to accommodate the rare
7025 case in which getmntent is available in none of the libraries
7026 checked. This happens at least on FreeBSD 5.0.
7028 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
7030 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
7031 ac_config_guess, ac_config_sub, and ac_configure, since evidently
7032 some other programs unwisely rely on these undocumented vars.
7033 But put in warning comments about them.
7034 Problem reported by Ralf Wildenhues in
7035 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
7036 * NEWS: Document that these variables are intended to go away.
7038 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7040 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
7041 and set the language to C++ (analogous to the equivalent Fortran
7044 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
7045 * doc/autoconf.texi (C++ Compiler): Document it.
7046 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
7049 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
7051 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
7052 that caused config.status to generate 100-command sed scripts; the
7053 portable limit is 99.
7055 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7057 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
7058 variable `ac_d' instead of `d' to avoid infringing namespace.
7059 Report by Ralf Menzel.
7061 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
7063 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
7064 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
7065 * tests/tools.at (autoconf: subdirectories): New test, taken from
7066 the corresponding problem report by Ralf Wildenhues in:
7067 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
7069 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
7070 Quote some uses of shell variables if they might suffer unexpected
7071 globbing. This doesn't fix all instances of quoting problems that
7072 I found, just the easy ones that look safe.
7073 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
7074 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
7075 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
7076 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
7077 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
7078 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
7079 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
7081 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
7082 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
7084 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7086 * bin/autoreconf.in ($help): Reword according to the manual.
7087 Suggested by Olly Betts.
7089 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
7090 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7092 * bin/autoreconf.in: Pass the directory argument to
7093 `require_configure_ac'. Fix comment.
7094 * tests/torture.at (Configuring subdirectories): Expose this.
7095 Reported by Olly Betts.
7097 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7099 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
7100 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
7101 Automake as follows:
7103 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
7104 `$configure_in' instead of `configure.in', to preserve
7105 directory component.
7107 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7109 * config/config.guess, config/config.sub, config/texinfo.tex,
7110 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
7112 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
7114 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
7115 test for C99 conformance; (bool) 0.5 is an integer constant
7116 expression, but (bool) -0.5 is not. Problem reported by Fedor
7117 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
7119 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
7121 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
7122 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
7123 Warn about obsolete install-sh files. Remove stray sentence
7124 fragment and fix cross reference.
7125 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
7126 install -d; this undoes the 2006-05-10 change.
7127 (MKDIR_P): Mark with AN_MAKEVAR.
7128 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
7129 that we don't require $INSTALL to be thread-safe. Move comments
7130 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
7131 of AC_PROG_INSTALL. Output a message saying that we're checking
7132 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
7133 MKDIR_P instead of AC_SUBST.
7134 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
7135 Special magic for MKDIR_P, too.
7136 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
7138 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
7140 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
7142 Sync from Automake, as follows:
7144 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7145 * config/install-sh: Initialize IFS, so field splitting isn't
7147 * config/mkinstalldirs: Likewise.
7148 * config/missing: Remove superfluous quotes. Replace all uses of
7149 `[' by `test', for consistency, and for..
7150 * config/missing (sed_minuso, sed_output): New variables.
7151 (autom4te, help2man, makeinfo): Use them. Unifies detection of
7152 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
7153 Fixes `missing' to detect `--output' for help2man. Fixes
7154 PR automake/483. Report by Dennis J. Linse.
7155 (autom4te): Document in `missing --help'.
7157 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
7159 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
7160 * config/install-sh: Don't use 'path' to talk about file names,
7161 as per GNU coding standards. Close a race condition reported by Ralf
7162 Wildenhues and Stepan Kasal. There is still a race condition
7163 on hosts that predate Posix 1003.1-1992, but we can't help this.
7164 Don't mishandle weird characters like space on pre-Posix hosts.
7165 Invoke mkdir at most once per dir arg on pre-Posix hosts.
7166 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
7167 AC_PROG_MKDIR_P from AS_MKDIR_P.
7168 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
7169 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
7170 earlier editions are not (including Automake 1.8.3).
7171 Do not suggest mkinstalldirs for thread-safety.
7172 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
7173 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
7174 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
7175 presence of special characters and race conditions.
7176 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
7177 in Autoconf's name space.

7180 and Paul Eggert <eggert@cs.ucla.edu>
7182 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
7183 from Automake with minor changes.

7186 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
7188 * config/install-sh: Update to Automake CVS version, as follows:
7189 2006-04-25 Stepan Kasal <kasal@ucw.cz>
7190 * lib/install-sh: Simplify the expr implementation of dirname.
7191 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
7192 * lib/install-sh: Handle --, and diagnose unknown options.
7194 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7196 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
7197 `./autom4te' to create `./testsuite', since the `all' target
7198 will ensure its presence, but `installcheck' should not create
7199 the uninstalled wrappers.
7201 * tests/torture.at (Unusual Automake input files): Skip if we
7202 detect automake < 1.8.
7204 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7206 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
7207 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
7208 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
7211 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7213 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
7214 munge (multiple) white space and other oddities.
7215 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
7216 single quotes in variable assignment.
7217 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
7218 and similar failures by adding multiple spaces, tabs, and other
7220 Report and different test suggested by Francesco Romani
7221 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
7223 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
7224 single quotes, we only need to search for single quotes; this
7225 both simplifies the search pattern, and makes us less
7226 susceptible to `echo' variations for arguments not containing
7228 (_AC_ARG_VAR_VALIDATE): Likewise.
7230 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7232 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document

7243 * doc/autoconf.texi: Use @option systematically.
7245 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
7246 and Bruno Haible <bruno@clisp.org>
7248 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
7250 (Integer Overflow): Mention the special case of integer division
7253 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7255 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
7256 traditional shells like the Solaris one that do not use the
7257 first IFS character for assembling `$*'.
7258 Prompted by a related report from autoconf_bug@nro.ca.
7260 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
7261 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7282 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
7283 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
7284 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
7286 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7288 * doc/autoconf.texi (Limitations of Make): Clean up markup.

7294 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7296 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
7297 /bin/sh set unsorted output.

7306 (Writing Test Programs): Fix some langauge. Recommend exiting
7307 with status 1, not merely nonzero. Clarify exit declaration.
7308 (Run Time): Move C exit status stuff to new Exiting Portably section.
7309 (Systemology): Mention Posix and levenez. Update v7 reference.
7310 (Portable Shell): Mention the Posix shell.
7312 2006-04-25 Stepan Kasal <kasal@ucw.cz>
7314 * bin/autoconf.as (me): Replace by as_me.
7316 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
7318 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
7319 since as_me isn't set yet.
7321 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
7323 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
7324 a few minor bugs in this area.
7326 * doc/autoconf.texi (Programming in M4sh): Comment out the
7327 documentation of AS_BASENAME, for now.
7328 (Shell Substitutions): Do not use AS_DIRNAME in an example.
7329 (Limitations of Builtins) <basename>: Do not refer to
7331 * bin/autoconf.as (me): Don't use AS_BASENAME.
7332 (dir): Remove the unused variable.
7333 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
7334 AS_DETECT_REQUIRED. All uses changed.

7342 (_AS_DIRNAME_PREPARE): Likewise.
7343 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
7344 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
7345 (AS_DIRNAME): Use "dirname --".
7347 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
7349 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
7350 of "run time" and "run-time" changed to "runtime", for consistency.
7351 * lib/autoconf/fortran.m4: Likewise (in comment).
7352 * lib/autoconf/functions.m4: Likewise.
7353 * lib/autoconf/general.m4: Likewise.
7354 * lib/autoconf/headers.m4: Likewise.
7356 * doc/autoconf.texi (Run Time): Document the exit status situation
7357 with more accuracy and detail.
7359 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7361 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
7362 Archive is not officially `GNU' any more. Update URL.
7363 (Defining Directories): Likewise
7364 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
7366 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7368 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
7369 newline from the `trap' code to finish `config.log'; the NetBSD
7370 /bin/sh resets the exit status after an empty command, as
7371 documented in doc/autoconf.texi.
7372 Reported by Dalibor Topic <robilad@kaffe.org>.
7374 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
7376 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
7377 Suggested by Bruno Haible.
7379 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
7381 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
7382 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
7383 Instead, just list the shells that we know work.
7384 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
7385 changed. Be more cautious about the _cv_ variable.
7386 * tests/tools.at (Syntax of the shell scripts): Check the
7387 _cv_ variable once, at first, to avoid an internal autoconf error
7388 when sh -n does not work.
7390 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7392 * lib/Autom4te/FileUtils.pm: Sync from Automake.
7394 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
7396 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
7397 use ">&-" since we're only 99.999% sure that this is portable,
7398 and since the MinGW bug is fixed in a different way.
7399 * lib/autotest/general.m4 (AT_INIT): Likewise.
7401 2006-04-16 Stepan Kasal <kasal@ucw.cz>
7403 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
7404 before opening config.log, to avoid hitting a bug on MinGW.
7406 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
7408 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
7409 AS_MESSAGE_LOG_FD before reopening it onto the log file.
7410 This works around a MinGW bug reported by Eric Paire.
7411 Make sure that all writes to the log file append to it,
7412 rather than possibly losing data.
7413 * lib/autotest/general.m4 (AT_INIT): Likewise.
7415 2006-04-14 Stepan Kasal <kasal@ucw.cz>
7417 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
7420 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7424 * configure.ac (AC_INIT): Bump to 2.59d.
7426 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7430 * Makefile.maint (news-date-check): Do not require a leading `*'
7431 before the release date in NEWS.
7433 2006-04-12 Stepan Kasal <kasal@ucw.cz>
7434 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7436 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
7437 the instantiated file do not contain the string 'datarootdir'
7438 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
7439 @mandir@, replace the reference '${datarootdir}' by the value.
7440 * tests/torture.at (datarootdir workaround): New test.
7441 * NEWS: Advertise this temporary fixup.
7442 Based on a patch by Bruno Haible, reported and analyzed by
7443 Paul Eggert and Noah Misch.
7445 2006-04-12 Eric Blake <ebb9@byu.net>
7447 * tests/autotest.at (Debugging a failed test): Fix comment.
7449 2006-04-12 Stepan Kasal <kasal@ucw.cz>
7451 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
7452 all the changes since 2006-04-07.
7454 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7456 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
7457 succeeded, but `ln -s file dir' failed, take care to remove the
7458 leftover target before the next test, to prevent its spurious
7459 failure; also make sure `ln file dir' works before selecting it.
7460 Thanks to Keith Marshall for pointing this out.
7463 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
7464 assignments in `at_debug_args', so that we put them correctly
7465 in the `run' script.
7466 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
7467 Reported by Eric Blake.
7469 2006-04-11 Eric Blake <ebb9@byu.net>
7471 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
7472 top-level tests after micro-suite has been run. Used in...
7473 (Debugging a successful test, Debugging script and environment),
7474 (Debugging a failed test): ...these new tests. The first of these
7476 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
7477 macro, split out from...
7478 (AT_INIT): ...here, so that using -d also generates a run script.
7479 Document that -d inhibits top-level logging.
7480 * doc/autoconf.texi (testsuite Invocation): Document that -d only
7481 inhibits top-level logging; debug scripts are created.
7483 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
7485 * tests/autotest.at (Empty test, Empty check): New test to check it.
7487 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
7490 2006-04-10 Stepan Kasal <kasal@ucw.cz>
7492 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
7493 the files if a problem appears. Make the empty *.at files
7494 read-only, too. Proposed by Ralf Wildenhues.
7496 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7498 * config/Makefile.am: Add comment to force updated Makefile.in.
7500 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
7501 space only patch to this file, this patch causes the Makefile.in
7502 files that include freeze.mk to be updated, and thus have a
7503 newer time stamp again, which in turn makes a pristine CVS
7504 checkout have correct time stamps.
7506 * Makefile.maint (cvs-sv): New macro, to be used..
7507 (config.guess-url_prefix, config.sub-url_prefix)
7508 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
7509 point to CVS text checkout of Gnulib files.
7510 (copyright-check): Bump current year.
7511 (announcement): Do not hard-wire `./announce-gen'.
7512 (cvs-update): Propagate failures of `cvs' and `move-if-change'
7514 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
7516 (wget_files): Update config.guess, config.sub, texinfo.tex by
7517 `wget-update', now that their URLs work again.
7519 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
7521 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
7522 Problem noted by Paul D. Smith.
7524 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7526 * doc/autoconf.texi: Remove unused words from word list.
7527 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
7528 .x-sc_trailing_space: New files.
7530 * doc/standards.texi: Sync from gnulib.
7532 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
7533 `LIBOBJDIR' as experimental.
7535 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
7536 with a target directory; it's internally implemented as `cp'
7537 anyway, but since Autoconf advertises the possibility to use
7538 a target directory when LN_S is `ln -s', we need to find out.
7539 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
7540 analyzed by Keith Marshall <keith.marshall@total.com>.
7544 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
7546 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
7547 confdefs.h as-is. In general, if it has backslash-newline or the
7548 like, then it doesn't work either to sort or to remove empty
7551 2006-04-09 Stepan Kasal <kasal@ucw.cz>
7553 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
7555 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
7557 * lib/autom4te.in (Automake-preselections): Preselect
7560 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
7562 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
7563 apostrophe within a single-quoted string, as this is the usual
7564 tradition and is easier to read than '"'"'. Don't rely on the
7565 shell treating "$/" like '$/'. Use a more-consistent indenting
7568 2006-04-09 Eric Blake <ebb9@byu.net>
7570 * tests/autotest.at (Backquote command substitution),
7571 (Multiline backquote command substitution): Remove mistaken
7572 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
7574 (Parenthetical command substitution, Multiline parenthetical
7575 command substitution): here.
7577 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
7579 Import macros from gnulib (often changing their name).

7610 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
7611 (C Compiler): Move AC_C_LONG_DOUBLE to ...
7612 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention

7654 Revert the patch from 2006-04-01 and only improve
7655 _AS_DETECT_BETTER_SHELL:
7657 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
7658 skip nonexistent directories.
7659 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
7660 only shell candidates which exist.
7661 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
7662 * lib/autotest/general.m4 (AT_INIT): No need to give three
7663 parameters to _AS_PATH_WALK.
7665 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
7666 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7668 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
7669 distinguish m4sugar macros.
7670 * tests/tools.at (autoupdating with aclocal and m4_include):
7671 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
7672 test case by Noah Misch <noah@cs.caltech.edu>.
7674 2006-04-07 Stepan Kasal <kasal@ucw.cz>
7676 Revert my change from 2006-03-17, in other words:
7677 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
7679 (AS_SHELL_SANITIZE): Remove DUALCASE=1.

7683 2006-04-07 Eric Blake <ebb9@byu.net>
7685 * doc/autoconf.texi (Programming in M4sh): Document that
7686 AS_MKDIR_P exits the script on failure.
7687 * lib/autotest/general.m4: Remove redundant AS_ERROR.
7689 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7708 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7710 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
7711 whether `set' quotes correctly: redirect stderr of the tested
7712 `set', and use a subshell, for Ultrix; use `sed' instead of
7713 `grep' for zsh `set' which may write binary output; match only
7714 at the beginning of a line, to avoid false positives.
7715 In order to avoid false positives by unrelated variables with
7716 multiline content, put the dump algorithm in a subshell and
7717 unset all variables containing newlines (except some which are
7718 special to the shell). Warn about cache variables that are

7764 ac_config_<foo>s again, sometimes normalized, sometimes not.
7765 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
7766 (AC_CONFIG_COMMANDS): Do not do so here.
7767 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
7768 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
7769 2005-07-25 rewrite. Noticed by Noah Misch.
7771 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
7772 _AC_PRESERVE_HELP_ORDER, ...
7773 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
7775 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once

7778 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
7779 for --help from Cygnus `configure.'
7781 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

7823 normalizing it, consistent it with previous releases.
7824 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.

7828 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
7829 Use simplified args that Eric Blake originally suggested.
7831 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
7833 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
7834 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
7835 Use 'comm' rather than N instances of grep; this also fixes a bug
7836 whereby substrings were incorrectly matched, causing us to not
7837 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
7838 (exclude_list): Exclude empty macros.
7839 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

7922 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
7923 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
7924 ac_file to the name of the default output file and call
7925 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
7926 initial `rm' of the candidate files...
7927 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
7928 the same list in subsequent `rm' calls, and for the temporary

7931 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
7932 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
7933 no longer needed) by libtool. Make it a cache check.

7935 copied here by mistake.

8010 2006-04-01 Stepan Kasal <kasal@ucw.cz>
8012 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
8013 switch all of them on and of when necessary. Fixes the bug when

8630 CONFIG_SHELL in the environment of the configure rerun.
8631 * doc/autoconf.texi (Here-Documents, config.status Invocation):
8632 Suggest passing CONFIG_SHELL absolute, and in the environment
8633 rather than as option.

8654 Factor functionality to..
8655 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
8656 `AC_SUBST($1)' in the public version.
8657 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
8658 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

8683 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
8684 conftest.o, to see whether the compiler really obeys; rm the object
8685 file before and after the test and register it with ac_clean_files.

8708 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
8709 AC_LANG_PROGRAM, fixing a typo. Don't give details about
8710 the inner workings of AC_LANG_FUNC_LINK_TRY.
8711 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
8712 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
8713 by the function rather than ignoring it.
8714 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
8715 comparing its address. Intel's interprocedural optimization was
8716 outsmarting the old heuristic. Problem reported by
8719 2005-10-19 Stepan Kasal <kasal@ucw.cz>
8721 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
8723 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
8725 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
8726 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
8728 2005-10-04 Stepan Kasal <kasal@ucw.cz>
8730 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
8731 before removing it (chmod -R u+rwx); there are three instances of this.
8733 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8734 Stepan Kasal <kasal@ucw.cz>
8736 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
8737 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
8738 make its content writable before removing it. Remove an errorneous
8739 comment from the end, where the logs of the failed tests are copied
8740 to the main log file.
8742 2005-09-27 Stepan Kasal <kasal@ucw.cz>
8744 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
8745 in case the computer is too quick. Double quote the configure.ac
8748 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
8749 problems if the testsuite were running too fast.
8751 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
8753 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
8754 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
8755 (which belong to Xt, not X itself). See Debian bug 327655.
8756 * NEWS: Mention this.
8758 2005-09-07 Stepan Kasal <kasal@ucw.cz>
8760 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
8762 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
8764 * config/move-if-change: Don't output "$2 is unchanged";
8765 suggested by Ben Elliston. Handle weird characters correctly.
8767 2005-09-06 Stepan Kasal <kasal@ucw.cz>
8769 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
8770 calls, so that the final expansion of this macro is shorter.
8771 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
8772 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
8773 the cleanup there. Use AS_VAR_* macros, to be more general.
8774 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
8776 * lib/autoconf/general.m4: Use AS_IF where appropriate.
8778 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
8780 2005-09-01 Stepan Kasal <kasal@ucw.cz>
8782 * doc/autoconf.texi (Configuration Headers): Add an index entry
8785 2005-08-26 Pavel Roskin <proski@gnu.org>
8787 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
8788 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
8791 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
8793 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
8794 The previous patch didn't work, so try a better one.
8796 2005-08-26 Stepan Kasal <kasal@ucw.cz>
8798 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
8799 in the example. Reported by Bruno Haible.
8800 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
8801 "if $undefined_var;" succeeds with my shell.
8803 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
8804 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
8805 but change the m4_divert_text to m4_divert_once.
8807 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
8809 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
8810 Work around bug in Solaris /usr/xpg4/bin/awk.
8811 The bug is present in at least Solaris 8 through 10.
8813 2005-08-24 Stepan Kasal <kasal@ucw.cz>
8815 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
8816 some evil values and relying on the fact that $* concatenates the
8817 parameters by the first character from IFS.
8819 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
8820 Stepan Kasal <kasal@ucw.cz>
8822 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
8823 first header appears, define AH_HEADER.
8824 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
8825 Update limitations about when to call AC_CONFIG_HEADERS.
8826 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
8827 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
8828 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
8829 ``Configuration Actions''; fix their index entries.
8831 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
8832 options correctly. Process N-M as M-N if M is smaller than N.
8833 Process ranges correctly so that N-N will run only N.
8834 Sort and uniquify the tests that will be run. If there is more
8835 than one test, reinsert the banners for the tests.
8836 * tests/autotest.at (Keywords): Unmark XFAIL.
8838 2005-08-23 Stepan Kasal <kasal@ucw.cz>
8840 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
8841 before passing the macro name to AH_TEMPLATE.
8843 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
8844 now opens log after option processing; in particular, --version
8845 and --help do not touch config.log.
8847 * Makefile.maint: Revert the change from 2005-08-12.
8849 2005-08-22 Stepan Kasal <kasal@ucw.cz>

8857 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
8858 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
8861 * doc/autoconf.texi (Defining Symbols, Changed Results):
8862 Prepend to LIBS, not append, in examples.
8864 2005-08-16 Stepan Kasal <kasal@ucw.cz>
8866 When building in place, set srcdir="."; suggested by Tim Van Holder.
8868 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
8869 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
8870 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
8871 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
8872 does not mean "no --srcdir option".
8874 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8876 * tests/autoscan.at (autoscan): New file.
8877 * tests/suite.at: Use it.
8878 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
8879 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
8881 * tests/autotest.at (Keywords): Test keywords combinations.
8883 2005-08-12 Stepan Kasal <kasal@ucw.cz>
8885 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
8886 add "2>&1"; gzip 1.2.4 prints help on stderr.
8888 2005-07-27 Stepan Kasal <kasal@ucw.cz>
8890 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
8891 was pushdef'ed twice while popped only once. Push it only once.
8892 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
8894 2005-07-26 Stepan Kasal <kasal@ucw.cz>
8896 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
8897 prefixed by mere "===", not "configure: === ".
8899 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
8901 * Makefile.maint: Update from Bison.
8903 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
8904 "<tab>" in comment, so that the point is understandable.
8906 2005-07-25 Stepan Kasal <kasal@ucw.cz>
8908 Rewrite substantial part of lib/autoconf/status.m4.
8909 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
8910 and CONFIG_COMMANDS are not processed in four separate loops.
8911 Instead, there is one main loop. This alows that the common code
8912 is expanded only once, thus config.status (and configure) is smaller.
8914 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
8915 the AC_LIST_FILES and cousins macros are no longer used.
8917 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
8918 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
8919 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
8920 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
8921 contain the initialization, nor the for loop, nor the associated
8922 commands; all these go to ...
8923 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
8924 _AC_OUTPUT_CONFIG_STATUS.
8925 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
8926 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
8927 (_AC_OUTPUT_FILE): The creation of the sed script ...
8928 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
8929 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
8930 _AC_OUTPUT_MAIN_LOOP.
8931 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
8932 _AC_CONFIG_COMMANDS): Use ...
8933 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
8934 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
8935 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
8936 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
8937 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
8938 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
8940 (_AC_CONFIG_UNIQUE): Update.
8941 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
8942 Replaced by this ...
8943 (_AC_LIST_TAGS): ... new common macro.
8944 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
8945 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
8946 (_AC_LIST_TAG_COMMANDS): ... new common macro.
8947 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
8948 this didn't belong to the `config commands' section.
8949 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
8950 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
8951 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
8952 to the `config commands' section either.
8953 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
8954 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
8956 ... and many changes to the comments nearby.
8958 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
8959 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
8960 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
8961 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
8962 (#define header templates): The comment at the top of the generated
8963 header now includes the name(s) of the source file(s).
8965 Several unrelated small changes:
8967 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
8968 parameter to AC_DIAGNOSE.
8969 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
8970 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
8971 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
8972 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
8974 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
8975 in AC_OUTPUT doesn't double-quote it either.
8976 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
8979 2005-07-10 Stepan Kasal <kasal@ucw.cz>
8981 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
8982 versions of Portland Group compiler produce single- and double-quoted
8983 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
8984 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
8986 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8988 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8989 This is a corrected version of yesterday's patch.
8991 2005-07-07 Stepan Kasal <kasal@ucw.cz>
8993 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
8994 path, too; insert a "===" to emphasize the line.
8996 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
8997 ac_cv_build_alias to ac_build_alias.
8998 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
9000 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
9001 change eliminates it. Problem reported by Alexandre Duret-Lutz.
9002 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
9003 (AC_ARG_VAR): ... here.
9004 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
9007 Keep a list of all precious variables and process them with one simple
9008 for loop, instead of expanding all commands, or, OTOH, complicated
9009 processing of output of "set".
9010 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
9011 variable names in new macro...
9012 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
9013 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
9014 a loop to assign all ac_env_* and ac_cv_env_* variables.
9015 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
9017 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
9018 its value to shell variable ac_precious_vars and call
9019 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
9020 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
9021 _AC_ARG_VAR_VALIDATE.
9023 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
9024 and the AC_SUBSTs ...

9028 the ac_subst_files section in config.log.

9046 Fix my changes from 2005-07-01; reported by Noah Misch.
9047 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
9048 description, the macro now accepts only a single tag.

9056 is not set, use at_top_builddir, for compatibility with older
9057 versions of autoconf.
9059 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
9061 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
9062 Problem reported by Patrick Welche.
9064 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
9066 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
9067 sed substitution command, so that we allow | in program prefixes
9068 and program suffixes. (& is a problem anyway; we're not fixing
9070 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
9071 configure_input, top_builddir, srcdir, etc.
9072 * lib/autotest/general.m4 (AT_INIT): Likewise, for
9073 PATH_SEPARATOR in AUTOTEST_PATH.

9106 document to output the default config_* lists to config.status.
9107 Don't recognize option --file, if the functionality is not there.
9108 Likewise for --header; moreover, recognize --he and --h as shortcuts
9109 for --help in that case.
9111 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
9112 matches the order of execution. No code changed.

9131 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
9133 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
9134 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
9135 (AC_SUBST): Call it.
9136 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
9137 the directory specific variables; but don't call it for configure_input.
9139 2005-06-28 Derek Price <derek@ximbiot.com>
9141 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
9144 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
9146 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

9163 from Justace Clutter.
9164 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
9165 variable into diagnostic. Make the diagnostic an error, not a warning,
9166 because we really don't support spaces and suchlike in dir names.
9167 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
9168 Don't worry about backslashes in srcdir; it can't happen now.
9169 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
9170 Simplify ac_optarg handling.

9179 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
9181 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
9182 that '\|' is not allowed in BREs; recommend using newline separated
9183 list of patterns instead of multiple -e options.
9185 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
9187 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

9195 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
9196 b, t, r, w commands require single space, while : cannot have any.
9197 (Special Shell Variables): Fix sed code this in the example.
9198 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
9199 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
9201 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

9207 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
9209 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
9211 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
9212 * doc/autoconf.texi:
9213 Don't mention Solaris versions so much, if a
9214 problem is common to all extant versions of Solaris. Say "SunOS
9215 4" instead of "SunOS" for SunOS 4.
9216 (awk): Mention more of the limitations of traditional Awk.
9217 (cat): Don't talk about cat -v.

9233 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
9235 * doc/autoconf.texi: "filesystem" -> "file system".
9236 "behaviour" -> "behavior".
9237 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
9238 * lib/autoconf/general.m4: Omit blank after ":" sed command,
9240 * lib/m4sugar/m4sh.m4: Likewise.
9241 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
9242 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
9244 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
9245 (.x.1): Ignore the time stamp in the .TH line when deciding whether
9246 to update the man page. That way, we don't have to check in new

9257 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
9259 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
9260 -u, since it outputs chatter if the input files are the same.
9261 Problem reported by Ralf Menzel.
9263 2005-06-08 Derek Price <derek@ximbiot.com>
9265 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
9266 renaming them since they are about to be redefined anyhow.
9268 2005-06-08 Derek Price <derek@ximbiot.com>
9270 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
9271 redefined M4 macros to this node. Document m4_include & m4_sinclude.
9272 Move m4_undefine to alphabetical order.
9274 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
9276 * README: Recommend GNU M4 1.4.3 or later.
9277 * doc/autoconf.texi (Introduction): Likewise.
9278 Reword to avoid some formatting glitches.
9279 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
9280 Clarify explanation of HP compiler bug.
9281 Redo example output tp match current CVS snapshot.
9282 Use @example.org in email addresses when the examples
9283 might get inadvertently cut-and-pasted into user code.
9284 Remove example of autom4te usage that doesn't seem to work now.
9285 Use modern AC_INIT (except when the example is meant to be
9286 shown with Autoconf 2.13).
9287 Update ksh info for Solaris 9 and later.
9289 Modernize description of Automake versions a bit.
9290 Don't claim a future version of Autoconf is near.

9296 follows its own advice about quoting better.
9297 Reword to avoid some formatting glitches.
9298 * doc/installt.exi: Reword to avoid some formatting glitches.
9300 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
9301 Tru64 ksh pattern matching bug. Reported against Libtool by
9302 Albert Chin <libtool@mlists.thewrittenword.com> and
9303 Nicolas Joly <njoly@pasteur.fr>.
9305 2005-06-06 Stepan Kasal <kasal@ucw.cz>
9307 m4_cdr of one-member list was [[]] (one-member list containing an
9308 empty string) instead of [] (an empty list. Callers were skewed to
9309 match this misbehaviour. As a consequence of this:
9310 - m4_foreach([x], [], [foo]) expanded to `foo', while
9311 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
9312 This bug has been fixed:
9314 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
9315 expand to an empty string; print error msg if called without
9317 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
9318 misbehaviour; handle [] and [[]] correctly.
9320 2005-06-06 Stepan Kasal <kasal@ucw.cz>

9326 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
9328 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
9329 swallow records with more than 99 fields.
9330 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
9331 parse the long line.
9333 2005-06-04 Stepan Kasal <kasal@ucw.cz>
9335 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
9336 swallow literals longer than 399. Reported by Ralf Wildenhues.
9337 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
9338 to workaround this limitation.
9340 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
9342 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
9343 to gfortran, and make these the first two compiler names
9344 checked (following the general autoconf preference for gcc).

9348 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
9349 (DISTCLEANFILES): Remove $(check_SCRIPTS).

9354 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
9355 expression of unbounded size when processing the --list
9356 option. This runs afoul of a limit of 399 bytes per regular
9357 expression on AIX. Problem reported by Ralf Wildenhues.
9359 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

9362 * doc/autoconf.texi (Particular Headers): Reword example
9363 for multiline stdbool replacement.
9364 (Setting Output Variables): Reword text a bit. Don't
9365 give all the details about |#_!!_#|.
9366 Reword description of line replacement.
9368 2005-05-31 Dan Manthey <dan_manthey@partech.com>
9370 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
9371 now contain newlines, and substituted files must be referenced on
9372 a line alone; the sed scripts to substitute them are now very
9374 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
9375 commands can be put in a sed script portably.
9376 * doc/autoconf.texi (Setting Output Variables): Document above
9377 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
9378 use of multiline substitution.

9388 * tests/local.at: Don't attempt to check for negated character
9389 classes in shell scripts. The test was too brittle.
9391 2005-05-25 Stepan Kasal <kasal@ucw.cz>
9393 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
9394 * doc/autoconf.texi (Limitations of Builtins): Document this
9397 2005-05-24 Stepan Kasal <kasal@ucw.cz>
9399 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
9400 common code; used in many places in the tree.
9401 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.

9407 messages when ac_unique_file is not found.
9408 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
9409 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
9410 commands, for consistency with AC_MSG_ERROR and such.

9425 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
9426 (ac_top_builddir): ... this ...
9427 (ac_top_build_prefix): ... to this; the old name is also kept, for
9428 backward compatibility.
9429 (ac_top_builddir_sub): New variable, without the trailing slash,
9431 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

9445 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
9446 argument to m4_foreach. I guess it was necessary in the past,
9447 but I think it's a no-op now.

9451 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
9452 ``cat <<_ACEOF'' commands to one.

9458 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
9460 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
9461 the wrong patterns between ``case'' and ``esac.'' The previous

9530 * doc/autoconf.texi (Autoconf Language): Be more precise about
9531 quoting rules. Problems noted by Stepan Kasal.
9532 Also, throughout this document, be more careful about white space.
9533 "blank", "white space", and "space" all have different meanings
9534 and we should be careful to say what we mean.

9554 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
9555 set by latest automake.
9557 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
9559 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
9560 outputs 0 on GNU/Linux these days.

9570 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
9573 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
9574 by AC_DEFINE; it was a mistake.
9575 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
9577 2005-04-25 Stepan Kasal <kasal@ucw.cz>
9579 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
9581 2005-04-22 Stepan Kasal <kasal@ucw.cz>
9583 * doc/autoconf.texi (External Software): Quadrigraphs are not
9584 processed correctly in AS_HELP_STRING; avoid this in the examples.
9585 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
9586 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
9587 comment and reduce m4_default([foo], []) to [foo].
9588 (m4_strip): Update the explanation.
9590 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
9592 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):

9594 Problem reported by Jennis Pruett.
9595 * lib/autoconf/functions.m4
9596 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

9644 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
9645 Merge `-z option' as well for the benefit of Solaris link flags. Pass
9646 whole-archive (-zallextract, -zdefaultextract) options in the hope of
9647 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
9648 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
9650 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
9652 * NEWS: The configure command now warns you if you attempt to use
9653 a directory whose name contains a special character like space,
9655 * doc/autoconf.texi (Installation Directory Variables): Allow
9656 "," in file names. Do not use \@; it's not a portable regexp.

9665 unportable file names.
9666 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
9668 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
9669 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
9670 ac_pwd, and quote srcdir.
9671 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
9673 * doc/autoconf.texi: Fix some systematic formatting problems.
9674 ".)" needs a following @: if not at the end of a sentence, and
9675 similarly for "!)". "etc." should be preceded by a comma.
9676 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
9678 2005-03-22 Bruno Haible <bruno@clisp.org>
9680 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
9681 argument is often called 'build-aux'.
9683 2005-03-07 Stepan Kasal <kasal@ucw.cz>
9685 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
9686 macro AC_TRY_LINK is obsolete.
9687 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
9690 2005-02-24 Stepan Kasal <kasal@ucw.cz>
9692 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
9693 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
9694 from a Common Lisp's `cl'.
9695 (AC_PROG_CXX): Behave according to the documentation: don't
9696 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
9697 make the variable CCC precious; use `cl.exe', not `cl'.
9699 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
9700 Alexandre Duret-Lutz <adl@gnu.org>
9702 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
9703 /dev/null, as "configure" shouldn't read stdin, and this insulates
9704 us from problems (e.g., when testing for "cl"). Also, do this
9705 redirection before invoking "hostname" or "uname", and keep the
9706 original input stream available via...
9707 (AS_ORIGINAL_STDIN_FD): ... this new macro.
9708 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

9720 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
9721 newline if neither \c nor -n work, as that would output two
9722 newlines. Prefer -n to \c. Reported by Stepan Kasal.
9724 2005-02-12 Stepan Kasal <kasal@ucw.cz>
9726 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
9727 This causes that any required macros inside will get before the if.
9728 * doc/autoconf.texi (autom4te.cache): A typo.
9730 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
9732 Undo previous change, except keep the change to
9733 lib/autoconf/programs.m4 that replaced grep with shell
9734 pattern-matching. This is because net-snmp configure reads stdin.
9735 Reported by Noah Misch.
9737 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
9739 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
9740 from /dev/null, as "configure" shouldn't read stdin, and this
9741 insulates us from problems (e.g., when testing for "cl").
9742 Suggested by Alexandre Duret-Lutz. Also, do this redirection
9743 before invoking "hostname" or "uname".
9744 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
9745 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
9746 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
9747 "</dev/null" since it's now done at the top of 'configure'.
9748 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
9749 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
9750 Also, replace grep with shell pattern-matching, to save a process.
9752 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
9754 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
9755 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
9756 avoid thinking that Allegro Common Lisp's "cl" command is a C++
9759 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
9761 * doc/autoconf.texi (Limitations of Usual Tools): Document that
9762 grep -q isn't portable. Improve grep -s explanation.
9763 Problem reported by Dan Manthey.
9765 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
9767 * doc/autoconf.texi (Special Shell Variables): Clarify
9768 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
9770 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
9772 * doc/autoconf.texi: Use @acronym for DJGPP.
9773 Fix some @code's that should have been @env's, and vice versa.
9774 Sort environment variable names.
9775 Mention that shells no longer inherit IFS.
9776 Don't recommend PATH_SEPARATOR=';' so strongly.
9777 Mention that $RANDOM might expand to the empty string.
9778 "symlink" and "soft link" -> "symbolic link".
9779 Improve mktemp description (reported by Bruno Haible).
9781 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
9783 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.

9812 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
9813 (Standard regular expressions): New test.
9814 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
9815 excess test name quoting.
9816 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass

9819 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
9820 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

9855 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
9857 Try not to generated lines of unlimited length, as POSIX places a
9858 2047-byte limit on line length of portable text files.
9859 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):

9873 * doc/autoconf.texi (Special Shell Variables): Mention _,
9874 BIN_SH, DUALCASE. Say that variables other than "status" are safe
9875 if they contain a lower-case letter. The DUALCASE problem was
9876 reported by Ralf Wildenhues.

9918 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
9919 Update the long comment explaining it.
9921 m4_require no longer writes an ``is required by'' line to the
9922 execution stack. It contains only one bit of non-redundant
9923 information: that the macro was required, not called. And even
9924 this bit is useless in most situations: have you ever met a macro
9925 which both calls and requires the same macro?
9927 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
9928 (_m4_defun_pro_outer): ... only via this macro, for the outermost
9930 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
9931 (m4_expansion_stack_pop): Remove the misplaced comment.
9932 (m4_require): Don't put the ``is required by'' line to the
9933 execution stack; slightly improve the out-of-a-defun error message.
9934 (_m4_divert_grow): New macro, counter for the temporary diversions.
9935 (_m4_require_call): Use it.
9936 * tests/m4sugar.at (m4_require): Expect output without the
9937 ``is required by'' messages.
9939 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

10347 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
10348 "char c = '\200';" rather than "char c = 0x80;" as the

10416 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
10417 the former ``test -f''.
10418 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
10420 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

10425 2004-11-10 Derek R. Price <derek@ximbiot.com>
10427 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
10428 limitations. Reorder paragraphs for clarity.
10430 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
10432 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
10433 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
10434 variants", "Unix", and some related minor wording fixups.
10436 (Shellology, Special Shell Variables): Document that the Zsh
10437 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
10438 to Alexandre Duret-Lutz for this info.

10449 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
10451 * doc/autoconf.texi (auindex): New macro.
10452 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
10453 Problem reported by Stepan Kasal.
10455 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
10457 Fix problems reported by Andreas Buening in:

10459 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
10461 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
10462 readable; it's not true in OS/2-emx.
10464 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
10466 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
10467 "/usr/include", clear ac_x_includes instead of leaving it as "no"
10468 (trivial change). Problem and patch reported by Andrew Church in:
10469 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
10471 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

10498 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
10499 texinfo.tex for now (done by hand now).
10500 * Makefile.maint (wget_files, cvs_files):
10501 Remove ansi2knr.c; nobody uses it.
10502 (ansi2knr.c-url_prefix): Remove.
10503 (cvs-update): Fix test for failure. I don't know why it ever
10506 * doc/autoconf.texi: Update URLs, some of which went stale.
10507 Use @uref rather than @href.
10509 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
10510 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
10512 * config/config.guess, config/config.sub, config/elisp-comp,
10513 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
10514 doc/fdl.texi, doc/standards.texi: Sync with master copy.
10516 * NEWS, TODO, configure.ac, bin/autoscan.in,
10517 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
10518 doc/install.texi, lib/Autom4te/Configure_ac.pm,

10522 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
10523 tests/tools.at, tests/torture.at:
10524 Use "file name" rather than "filename" or "path",
10525 to be consistent with the terminology of the GNU coding standards.
10527 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
10529 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
10530 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
10531 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
10532 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
10534 More fixes to support spaces in the name of the build directory.
10535 This isn't a complete fix but it's an improvement.
10537 * bin/autoconf.as (autom4te_options): New var.
10538 Use it instead of appending to AUTOM4TE, so that we can allow
10539 spaces in the build directory's absolute name.
10540 * bin/autoheader.in ($autoconf): Allow spaces in file names.
10541 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
10542 AT_CHECK_NOESCAPE): Likewise.
10543 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
10544 main program): Likewise.
10546 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
10548 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

10552 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
10554 * doc/autoconf.texi (Function Portability): Document isinf and
10555 and isnan. From a suggestion by Kevin Ryde.
10557 * lib/Autom4te/General.pm (END): Return correct exit status even
10558 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
10560 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
10562 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
10563 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
10564 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
10566 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
10568 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
10569 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
10570 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
10571 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
10572 * lib/autom4te.in (Automake-preselections): Preselect
10573 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
10575 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
10577 * lib/autom4te.in (Automake-preselections): Preselect
10578 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
10581 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
10583 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
10585 * doc/autoconf.texi (Shellology): Mention BIN_SH.
10586 Document problem with "`""`" in pdksh POSIX mode.
10588 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
10590 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
10591 with pdksh, too. Problem reported by Patrick Welche via
10593 * doc/autoconf.texi (Shellology): Note that set -o posix is
10594 useful for pkdsh, too.
10596 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
10598 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
10599 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
10600 Don't fail if ENV or BASH_ENV is readonly.
10601 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
10602 etc. are read only. Problem reported by Ludovic Courtes.
10604 2004-06-23 Noah Misch <noah@cs.caltech.edu>
10606 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
10607 zsh, disable GLOB_SUBST to avoid backslash handling problems.
10610 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
10612 * doc/autoconf.texi (File System Conventions): Warn about
10613 names like "aux". Problem reported by Eric Blake.
10615 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
10616 by zero instead of array size, so that we can use any arithmetic
10617 constant expression (instead of requiring an integer constant
10618 expression). This allows us to test expressions like DBL_MAX <
10619 LDBL_MAX, which didn't conform to the C standard using the old
10621 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
10622 now that we can do floating-point tests at compile time.
10624 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
10626 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
10627 and LDBL_EPSILON, as the resulting expression isn't an
10628 integer constant expression and violates the C standard.
10629 Problem reported by Nelson H. F. Beebe. Also, check
10630 for "L" suffix, and check that long double doesn't have
10631 worse range or precision than double, that mixed-mode
10632 arithmetic doesn't generate a diagnostic, that double
10633 constants fit in long double.
10635 2004-06-03 Kevin Ryde <user42@zip.com.au>
10637 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
10638 malloc(0) and realloc(NULL,size).
10640 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
10643 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
10645 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
10646 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
10649 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
10651 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
10652 can be rewritten using if-then-else. Suggested by Bruno Haible.
10654 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
10656 * doc/autoconf.texi (testsuite Scripts): Fix typo.
10657 Problem reported by Stepan Kasal.
10659 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
10661 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
10662 change). Patch reported by Ralf Wildenhues in
10663 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
10665 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
10666 function F exists if the compiler and linker let you compile an
10667 expression like (F != 0). Recent versions of GCC optimize away
10668 the reference to F in that case, since every function address must
10669 be nonzero, so the link succeeds even if F does not exist.
10670 Problem reported by Manu in
10671 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
10673 * doc/autoconf.texi (Systemology): Standardize on the spelling of
10674 "Unix". Many uses changed.
10675 (Limitations of Builtins): Explain better why the ! command isn't
10678 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
10680 * lib/autom4te.in (Automake-preselections): Preselect
10681 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
10683 2004-05-19 Kevin Ryde <user42@zip.com.au>
10685 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
10686 referencing AC_FUNC_STRERROR_R.
10688 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
10689 note pessimistic assumption when cross compiling.
10691 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
10693 * doc/autoconf.texi (Limitations of Make): Note that BSD make
10694 (until 2004) invoked subcommands with sh -e, contra POSIX.
10695 Reported by Kevin Ryde.
10697 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
10699 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
10700 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
10701 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
10702 `test -f " /usr/bin/grep"', which _always_ failed.
10703 (AC_PROG_SED): Ditto bogus PATH fix.
10704 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
10705 requires that grep correctly supports _multiple_ `-e' options, rather
10706 than stating only that grep should accept `-e'.
10708 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
10710 Port to C99, which requires that 'exit' be declared.
10712 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
10713 to ensure that stdlib.h is included.
10714 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
10715 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
10716 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
10717 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
10718 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
10719 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
10720 when using 'exit' in a test; C99 requires that 'exit' be declared.
10722 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
10724 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
10725 now prefers 'grep' implementations that accept -e.
10726 (Limitations of Usual Tools): Describe problems of traditional
10727 egrep and fgrep with long input lines, and of traditional grep
10729 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
10730 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
10731 All callers changed. Append /usr/xpg4/bin to the PATH, for
10733 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
10734 the user with complaints about multiple -e options.
10735 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
10736 Define it with AC_PROG_GREP.
10737 * configure.ac (AC_PROG_GREP): Add.
10738 * lib/freeze.mk (GREP): New macro.
10740 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
10742 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
10743 a possible candidate only after all others fail, rather than
10744 consulting it first. This improves backward compatibility by
10745 better reflecting the way shell selection occurred in previous
10746 versions of Autoconf, and should help to avoid triggering latent
10747 problems in other packages, such as the one in Automake where zsh
10748 is not handled robustly:
10749 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
10750 Although it is not Autoconf's responsibility to work around
10751 problems in Automake, it nevertheless makes sense to avoid
10752 introducing unnecessary incompatibilites.
10754 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
10755 Gary V. Vaughan <gary@gnu.org>
10757 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
10758 how deeply nested we are when a suitable tool is found, set the
10759 ac_path_TOOL_found flag.
10760 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
10761 nested we are in this macro. Break out of all 3 nested loops if
10762 ac_path_TOOL_found is set.
10764 2004-04-21 Gary V. Vaughan <gary@gnu.org>
10766 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
10767 of the _AS_PATH_WALK loop too if GNU flavor is found.
10769 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
10771 * doc/autoconf.texi (Limitations of Make): Update documentation
10772 for `$<'. New entry `Long lines', based on a report from Simon
10773 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
10774 paragraph about DJGPP, based on a mail from Richard Dawe.
10776 2004-04-20 Paul Eggert <eggert@twinsun.com>
10778 * tests/c.at (C keywords): Don't assume that GCC supports
10779 "restrict" and "inline", as sufficiently-old GCC versions do not
10780 (also, GCC configured to be in pedantic C89 mode does not).
10781 Problem reported by Sumit Pandya in:
10782 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
10784 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
10785 consider -g to work if it generates warnings when plain compiles
10786 don't. Problem reported by Braden McDaniel in:
10787 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
10789 * doc/autoconf.texi (Slashes): New section, to document a problem
10790 reported by Jim Meyering in:
10791 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
10793 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
10794 linker output files before linking, to work around IRIX 6 linker bug.
10795 Problem reported by Rainer Orth in:
10796 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
10798 2004-04-20 Gary V. Vaughan <gary@gnu.org>
10800 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
10801 best tool so far counter rely on the tool path variable name to
10802 avoid checks for one tool being affected by the results of running
10803 the length check on a previous tool.
10805 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
10806 match expression argument, as different greps have different
10807 regular expression flavours.
10808 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
10810 (AC_PROG_EGREP): Pass 'EGREP$'.
10811 (AC_PROG_GREP): Pass 'GREP$'.
10813 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
10815 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
10816 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
10818 2004-03-29 Paul Eggert <eggert@twinsun.com>
10820 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
10821 Types, Specific Compiler Characteristics, System Services,
10822 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
10823 etc. consistently instead of 'long', 'short', 'unsigned' etc.
10824 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
10825 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
10827 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

10836 2004-03-28 Paul Eggert <eggert@twinsun.com>
10838 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
10839 now defines HAVE_DECL_TZNAME if it is declared, when
10840 HAVE_STRUCT_TM_TM_ZONE is not defined.
10841 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
10842 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
10845 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
10847 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
10848 superfluous backslashing of quotes (") in sed expressions;
10849 thanks to Paul Eggert.
10851 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
10853 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel

10930 Fix a dependencies problem, stemming from a Autoconf 2.59 build
10931 problem on QNX reported by Stephen Rasku in

10934 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on

10943 AC_SUBST provides no portable way to escape literal newlines.
10945 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
10946 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
10947 Darwin uses -lcrt2.o and there's little point to cataloging all
10948 the system variants. Partial fix reported by Andreas Waechter in:

10974 Paul Eggert <eggert@twinsun.com>
10976 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
10977 (AS_INIT): Output shell initialization there. Removed optional
10978 parameter. Expand _AS_SHELL_FN_SPY.

10993 use AS_INIT_WITH_SHELL_FN.

11024 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

11026 the 2003-05-22 change, which removed the older years from the list.
11027 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

11040 _AC_PROG_GREP, and AC_PROG_SED.
11041 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
11042 longest input length accepted by a command.

11071 2004-01-26 Paul Eggert <eggert@twinsun.com>
11073 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
11074 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
11075 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
11076 not <inttypes.h>. Problem reported by Tim Mooney in
11077 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
11078 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
11081 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
11082 otherwise "make check" fails because it forbids cmp (I guess
11083 because cmp treats files as binary on DOS-like systems).
11085 * tests/mktests.sh: Update copyright date to 2004, since some tests
11086 have changed in 2004.
11088 2004-01-23 Gary V. Vaughan <gary@gnu.org>

11091 non-truncating sed or gsed program in PATH.
11092 * tests/acprograms.at: Add it.

11096 2004-01-15 Paul Eggert <eggert@twinsun.com>
11098 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
11099 -std1 disables some useful extensions on Tru64. Problem reported
11100 by N. Lichtmaier in
11101 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
11103 2004-01-14 Paul Eggert <eggert@twinsun.com>
11105 * doc/autoconf.texi (Programming in M4sh): Document that
11106 AS_MKDIR_P succeeds if the destination is a symbolic link
11107 to an existing directory.
11108 (Limitations of Usual Tools): Note that mkdir -p might not
11109 succeed on symlinks to directories.
11111 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
11113 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
11114 * bin/autoheader.in: Grammar fix in message.
11115 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
11116 Test for dir before calling mkdir -p. (trivial changes)

11123 2004-01-10 Jim Meyering <jim@meyering.net>
11125 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
11127 2004-01-09 Paul Eggert <eggert@twinsun.com>
11129 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
11130 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
11131 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
11132 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
11133 AC_COMPILE_IFELSE, since we now assume our caller invokes
11134 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
11135 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
11136 of AC_RUN_IFELSE; this avoids the warning mentioned above.
11137 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
11139 2004-01-07 Paul Eggert <eggert@twinsun.com>
11141 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
11142 `"'...'"`, as it's confusing (and I suspect it may not work on
11143 some platforms). The code was incorrect anyway, as it assumed
11144 that \$ evaluated to itself in that context. Reported by
11145 Alexandre Duret-Lutz.
11147 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
11149 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
11150 and _LT_AC_TAGCONFIG.

11177 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
11178 Use "rm -f" to remove conftest.sed, not plain "rm".
11179 Bug reported by David Relson in
11180 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
11182 * Makefile.am (autom4te-update):
11183 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

11200 -c -o might not work. From a suggestion by Kevin Ryde.
11201 (C Compiler, Generating Sources, Limitations
11202 of Usual Tools, Limitations of Make, Making testsuite Scripts):
11203 Don't put '-o' after non-options, as POSIX doesn't allow this.
11204 Mention that cc's name might be gcc or c89 or whatever.
11206 2004-01-04 Kevin Ryde <user42@zip.com.au>

11231 * tests/atlocal.in: Store the result here.

11236 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
11237 * tests/tools.at (Syntax of the shell scripts): Simplify

11322 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
11323 than $target since the latter is not usual, add guidelines on when to
11324 use or not use the system type.

11486 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
11488 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official

11501 Problems reported by Eric Sunshine.
11503 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
11505 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
11506 -mGLOB_options_string stuff for Intel ifc, which can cause
11507 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
11508 pattern-matching instead of grep.

11512 * doc/autoconf.texi: Document new FC Fortran macros.
11514 2003-10-08 Gary V. Vaughan <gary@gnu.org>
11516 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro

11530 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
11531 cache variable instead of $G77 to decide whether to include -O2,
11532 since $G77 is specific to Fortran 77.

11536 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
11537 free" flag. Re-order flags tested into rough order of popularity.
11539 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
11541 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
11542 arguments so that it can be used with syntax identical to
11543 AC_PROG_F77, and so that we can more easily decide to
11544 remove/deprecate the DIALECT optional argument in the future if it
11545 proves troublesome.
11546 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
11547 non-freeform-supporting compilers. Document freeform flags.
11549 2003-10-03 Akim Demaille <akim@epita.fr>

11611 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
11612 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
11613 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
11614 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
11616 2003-09-26 Akim Demaille <akim@epita.fr>
11618 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
11619 directory for AC_CONFIG_COMMANDS' first argument exists.
11620 This makes valid the invocation of _AC_SRCPATH that follows.
11621 Reported by Eric Sunshine.
11622 * doc/autoconf.texi (Configuration Commands): Adjust.
11624 2003-09-26 Akim Demaille <akim@epita.fr>

11645 The test suite are sometimes assigning timings incorrectly.
11646 Reported by Henk Krus.
11647 Diagnosed by Nicolas Joly.
11649 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
11651 Instead of making AT_help a sequence of assignments to grow
11652 $at_help_all, just make AT_help_all be the growing contents of
11653 $at_help_all, and make a single assignment in...
11655 (at_times_skip): Flip the meaning and rename as...
11656 (at_times_p): this.
11657 (AT_INIT): When summarizing the test that ran, remove
11658 $at_times_file after use, and check it is present before trying to

11667 (ifnames): chmod -w.
11668 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
11669 executables, not bin/ executables! Otherwise all the magic needed
11670 to find non installed files is turned off. This caused a failure
11671 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
11672 as found in its environment (sent by tests/autoreconf): pointing
11673 to bin/autom4te that could not find its files.
11674 * tests/mktests.sh: Force the replacement of generated files, for
11675 the sake of "mv" program that are interactive when overwriting a
11677 * config/install-sh: Upgrade from CVS Automake.

11682 versus test -L issues.
11684 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
11685 Paul Eggert <eggert@twinsun.com>
11687 Trivial change to support GCC's configuration procedure.

11723 willing to edit the output files.
11725 2003-09-10 Akim Demaille <akim@epita.fr>
11727 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
11728 and AC_FC_FREEFORM.
11729 * tests/mktests.sh: Skip AC_FC_SRCEXT.
11730 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

11750 2003-09-05 Paul Eggert <eggert@twinsun.com>
11752 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,

11770 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
11772 Add support for newer Fortran dialects. The F77 interface is
11773 unchanged, and continues to support Fortran 77. New FC macros
11774 correspond to all the old F77 macros, with output variables FC,
11775 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
11776 available dialect, but older dialects can be specified. There are
11777 new macros AC_FC_SRCEXT to set the source extension, and
11778 AC_FC_FREEFORM to accept free-form source files.
11780 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
11782 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

11904 2003-08-21 Akim Demaille <akim@epita.fr>
11906 First stab at preserving warnings between calls to autom4te,
11907 including when the cache is used.
11909 There are still several issues: (i) there are too many runs of m4
11910 (one for include, one for warnings, and some more), (ii) warnings
11911 spreading on several lines are not handled gracefully, (iii) the
11912 code meant to have the call stack display for errors does not work
11913 (its handling should move from m4 to autom4te).
11915 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
11917 (@preselect): Add m4_warn.
11918 ($exit_status): Remove, use $exit_code.
11919 ($help): Use Autom4te::ChannelDefs::usage.
11920 (&handle_m4): No longer define the m4_warnings.
11921 At each run, extract and report the warnings.
11922 Always cache the result, including if the exit status is on
11923 failure, since if nothing changes, we should result in the same
11924 failure, hence we can use the cache.
11925 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
11926 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
11928 (m4_warn): Redefine as a do-nothing: it is its invocation that
11929 matters, as warnings are now reported via traces.
11930 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
11931 the contents of m4_warn: make it _call_ m4_warn, so that tracing
11932 the latter reveals calls to the former.
11936 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

11969 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
11970 * bin/autom4te: Adjust.
11971 In particular, be Autoconf tools are really silent when properly
11972 working, bind the verbosity of the 'note' channel to $verbose.
11973 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)

12097 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
12098 not all of them. This fixes 1. the fact that when testing
12099 Autoconf there are many many config.log, 2. the incorrect use of
12100 top_srcdir to find config.log.
12101 Don't mix the detailed output of failed test with the summary of
12102 failures. Rather, append detailed log afterwards.
12104 2003-06-23 Akim Demaille <akim@epita.fr>
12106 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

12221 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
12222 Remove `#include <stdlib.h>' from the list; we should never
12223 make confdefs.h include <stdlib.h> or <cstdlib>, because the
12224 resulting namespace pollution would cause other tests to fail.
12225 Configure scripts run with some older versions of g++ and HP's
12226 aCC would fail due to such an #include. Problems reported by
12227 Matthew Mueller in <http://bugs.debian.org/120704> and by
12229 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
12230 In the test, use the test declaration before including <stdlib.h>,
12231 as that's closer to how it'll be used.

12238 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
12240 Overhaul Autotest's logging: generate separate log files
12241 in testsuite.dir/NNN/testsuite.log, and append them to
12242 testsuite.log instead of re-running the test verbosely.
12244 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
12245 file descriptor, write 0 to at_status_file instead of setting
12246 at_status=0, initialize some new variables (at_status_file,
12247 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
12248 to rerun the tests, instead append the at_group_log to the
12249 at_suite_log when a test fails.
12250 (AT_SETUP): pipe the test case's output into at_tee_pipe,
12251 with the AS_MESSAGE_LOG_FD redirected to stdout.
12252 (AT_CLEANUP): save the output status in $at_status_file
12253 and restore it, redirect the AS_MESSAGE_LOG_FD back to
12254 its original place.
12255 (AT_CHECK): since tests are run with a redirected stdout,
12256 and used to be re-run in verbose mode, turn some $at_verbose
12257 into echo, and don't redirect the output of testing stdout
12260 * lib/autotest/autoconf.texi (testsuite Scripts): Update
12261 the name of the debugging directory and information about

12664 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

12700 * Makefile.maint: Sync with Bison, i.e.:
12701 (po-check): Scan .l and .y files instead of the

12762 2002-11-05 Akim Demaille <akim@epita.fr>
12764 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
12766 We _have_ to stop using the old compatibility scheme that tried to
12767 avoid useless backslashes because Libtool 1.4.3 contains a
12768 AC_DEFINE([error_t], [int],
12769 [Define to a type to use for \`error_t' if it is not
12770 otherwise available.])
12771 We _have_ to quote the single quote and backslashes with \. The
12772 old compatibility scheme saw that ` was backslashed, and therefore
12773 did not quote the single quote. Hence before this patch, Autoconf
12774 was not compatible with Libtool.

13228 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
13229 aclocal invocation, as Gettext macros might not be visible to

13260 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13261 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
13263 2002-09-28 Akim Demaille <akim@epita.fr>
13265 * tests/torture.at (Configuring subdirectories): Be robust to
13266 users who use config.site to require for a cache: in this case,
13267 the two last configure runs, using two different sets of
13268 arguments, trigger a legitimate error.
13270 2002-09-28 Akim Demaille <akim@epita.fr>
13272 * tests/m4sh.at (Functions Support, Functions and return Support):
13275 2002-09-28 Akim Demaille <akim@epita.fr>
13277 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
13278 autoheader are Perl programs.
13279 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
13280 (autom4te): Specify that the sources are in the $srcdir.

13288 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
13289 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
13290 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

13303 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
13304 (.m4.m4f): Don't pass --prepend-include, since that's done by
13305 tests/autom4te itself.
13306 * lib/autoscan/Makefile.am: Include freeze.mk.
13307 (autoscan.list): New target --this file is no longer a source.
13308 (autoscan.pre): New file.
13310 2002-09-28 Akim Demaille <akim@epita.fr>
13312 * bin/autoscan.in (@kinds): Make them singular.
13314 (&init_tables): When --debug, report the list of rules to ease
13315 tracking changes in autoscan.list.
13316 * lib/autoscan/autoscan.list (function): Strip comments, sort.
13318 2002-09-28 Akim Demaille <akim@epita.fr>
13320 * lib/autoscan/functions, lib/autoscan/headers,
13321 * lib/autoscan/identifiers, lib/autoscan/makevars,
13322 * lib/autoscan/programs: Merge into...
13323 * lib/autoscan/autoscan.list: this.
13324 * bin/autoscan.in (&init_tables): Adjust.
13326 2002-09-28 Akim Demaille <akim@epita.fr>
13328 * lib/autoscan/functions, lib/autoscan/headers,
13329 * lib/autoscan/identifiers, lib/autoscan/makevars,
13330 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
13331 `functions' line is now prefixed with `function:'.
13332 * bin/autoscan.in (&init_tables): Adjust.
13334 2002-09-28 Akim Demaille <akim@epita.fr>
13336 From now on, autoscan files must always map a macro name to a
13337 word: there is no `default' macro for autoscan.
13339 * bin/autoscan.in (&init_tables): Reject entries with no macro at
13341 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
13344 2002-09-28 Akim Demaille <akim@epita.fr>
13346 * bin/autoscan.in (%c_keywords): Remove.
13347 (&used): Keep only track of the words we might be interested in.
13348 (&output_kind): It is no longer needed to look for non active
13351 2002-09-27 Akim Demaille <akim@epita.fr>
13353 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

13355 * lib/autoscan/functions: Adjust.
13356 * doc/autoconf.texi (Particular Functions): Adjust.
13358 2002-09-27 Akim Demaille <akim@epita.fr>
13360 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
13362 Thanks to Bill Moseley and Paul Eggert.
13363 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
13364 the tmpdir must be created.
13365 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
13366 dir be in the build tree, instead of $TMPDIR.
13368 2002-09-27 Akim Demaille <akim@epita.fr>
13370 * bin/autoscan.in: Improve the comments.
13371 (&parse_args): Drop obsolete undocumented options.
13372 (&output_kind): Output warnings.
13373 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

13378 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
13379 Reported by Ralf Corsepius.
13380 * doc/autoconf.texi (autoreconf Invocation): Likewise.
13382 2002-09-26 Akim Demaille <akim@epita.fr>
13384 Single suffix rules and seperated dependencies are not portable.
13386 * doc/autoconf.texi (Installation Directory Variables): Update.
13387 (Limitations of Make): Some about `Single Suffix Rules and
13388 Separated Dependencies'.
13389 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
13390 (ifnames, autoscan, autom4te): Un-factor into several rules.
13392 2002-09-25 Paul Eggert <eggert@twinsun.com>
13394 * BUGS (Interoperability bugs): New section. Mention libtool
13395 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
13397 2002-09-24 Paul Eggert <eggert@twinsun.com>
13399 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
13400 make handles suffix-rules differently from GNU make.
13402 * bin/Makefile.am (SUFFIXES, .in): Remove.
13403 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
13404 Move the body of the old .in rule here.
13406 2002-09-16 Akim Demaille <akim@epita.fr>
13408 i960 compilers create `b.out' files by default.
13409 Reported by Ralf Corsepius.
13411 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
13412 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
13414 2002-09-13 Paul Eggert <eggert@twinsun.com>
13416 * doc/autoconf.texi (Particular Headers): Remove obsolete
13417 reference to `struct timezone' in the description of
13420 2002-09-13 Akim Demaille <akim@epita.fr>
13424 * config/config.sub, config/config.guess: Update.
13425 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
13426 * Makefile.am: Adjust.
13428 2002-09-13 Akim Demaille <akim@epita.fr>
13430 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
13431 reading config.log when the compiler is rejected.
13432 Suggested by Guido Draheim.
13434 2002-09-13 Akim Demaille <akim@epita.fr>
13436 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
13437 (chdir_init) might hang when stat'ing mounted directories.
13438 Reported by Vance Shipley.
13440 2002-09-12 Akim Demaille <akim@epita.fr>
13442 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
13445 2002-09-12 Akim Demaille <akim@epita.fr>
13447 * doc/autoconf.texi (Defining Symbols): Present two different
13448 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
13449 difference between 1 argument calls, and 2-3 argument calls.
13451 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
13453 * doc/autoconf.texi: Review grammar and punctuation.
13455 2002-09-11 Paul Eggert <eggert@twinsun.com>
13457 * doc/autoconf.texi: Fix minor formatting, spelling, and
13459 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
13460 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
13463 2002-09-11 Akim Demaille <akim@epita.fr>
13465 * doc/autoconf.texi (Questions): Rename as...
13467 (Defining Directories): New.
13469 2002-09-09 Akim Demaille <akim@epita.fr>
13471 * doc/autoconf.texi (Making testsuite Scripts): Update.
13472 Suggested by Nishio Futoshi.
13474 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
13476 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
13477 plain `@' is wanted.
13479 2002-09-09 Akim Demaille <akim@epita.fr>
13481 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
13482 `duplicates', since the algorithm was too naive and could keep
13483 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
13484 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
13485 Reported by Ralf Corsepius.
13486 * tests/torture.at (Configuring subdirectories): Exercise these
13489 2002-09-09 Akim Demaille <akim@epita.fr>
13491 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
13492 looking for a replacement file.
13493 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
13494 directory is relative.
13495 * doc/autoconf.texi (Generic Functions): Clarify the replacement
13496 directory definition.
13497 Reported by Andreas Schwab and Jim Meyering.
13499 2002-09-06 Akim Demaille <akim@epita.fr>
13501 * doc/autoconf.texi (Setting Output Variables): Clarify what
13502 precious variables are.
13503 Suggested by Pontus Skoeld.
13505 2002-09-05 Akim Demaille <akim@epita.fr>
13507 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
13508 (ifnames, autoscan, autom4te): Since we don't only depend on
13509 configure.ac variables (such as VERSION etc.), but also on prefix
13510 and so forth, depend on Makefile, not configure.ac.
13511 Reported by Alexandre Duret-Lutz.
13512 * doc/autoconf.texi (Installation Directory Variables): Adjust.
13514 2002-09-05 Kevin Ryde <user42@zip.com.au>
13516 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
13517 doesn't seem to be confined to ia64, just say "some versions".
13519 2002-09-04 Akim Demaille <akim@epita.fr>
13521 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
13523 * Makefile.am (maintainer-clean-local): Remove.
13524 (MAINTAINERCLEANFILES): Remove COPYING.
13526 2002-09-03 Paul Eggert <eggert@twinsun.com>
13528 * doc/autoconf.texi (Configuration Commands): Remove obsolete
13529 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
13532 2002-09-03 Akim Demaille <akim@epita.fr>
13534 * configure.ac: Bump to 2.53d.
13535 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
13536 as of today, on Automake's team suggestion.
13538 2002-09-03 Akim Demaille <akim@epita.fr>
13542 2002-09-02 Akim Demaille <akim@epita.fr>
13544 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
13546 * configure.ac: Disable SITE_MACRO_DIR.
13548 2002-09-02 Jim Meyering <meyering@lucent.com>
13550 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
13551 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
13552 Also, tweak grammar: s/make sure to/be sure to/.
13554 2002-09-02 Paul Eggert <eggert@twinsun.com>
13556 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
13557 directory names are generally preferable to physical names.
13559 2002-09-02 Akim Demaille <akim@epita.fr>
13561 * lib/Autom4te/General.pm (&update_file): s/die/error/.
13562 Reported by Raja R. Harinath.
13563 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
13564 * bin/autoupdate.in: Use error instead of die.
13566 2002-09-01 Paul Eggert <eggert@twinsun.com>
13568 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
13569 ordinary shell concatenation rather than echo+tr+sed command that
13570 runs afoul of a long-line-related sed bug in Solaris 8.
13572 * bin/autoheader.in (parse_args): --warning -> --warnings.
13574 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
13575 stdout, as traditional "ls" does.
13576 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
13577 _AC_COMPILER_EXEEXT_O): Likewise.
13578 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
13580 * bin/autoconf.as: Add --prepend-include option. This patch was
13581 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
13582 but bin/autoconf.in is generated automatically from bin/autoconf.as.
13584 * bin/autoconf.in, configure: Regenerate.
13586 * doc/autoconf.texi (Special Shell Variables): Mention
13587 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
13589 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
13590 MAILPATH and set PS1, PS2, PS4 to default values, to work
13591 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
13592 For LC_ALL etc, first try to set to "C" as POSIX requires and as
13593 the Autoconf documentation specifies; fall back to "unset" only if
13594 this fails. Use a shell for-loop for this rather than an m4 loop,
13595 to shorten the output script.
13597 2002-08-30 Paul Eggert <eggert@twinsun.com>
13599 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
13600 1003.1-2001's requirements for CDPATH. Give a simpler workaround
13601 for the CDPATH problem. Document PWD.
13602 (Limitations of Builtins): Document the problem that "cd $foo" and
13603 "ls $foo" may refer to different directories in shells conforming
13604 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
13605 example, since the old example is now out of date.
13607 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
13608 FOO" and "ls FOO" talk about different directories; this catches
13609 problems when POSIX 1003.1-2001 "cd" fails due to symlink
13612 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
13613 of rolling our own unset.
13614 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
13615 in practice we needn't worry about CDPATH if unset doesn't work.
13617 * Makefile.in, aclocal.m4, bin/Makefile.in,
13618 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
13619 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
13620 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
13621 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
13622 tests/Makefile.in: Regenerate with Automake 1.6.3.
13624 * config/config.guess, config/config.sub, config/mkinstalldirs:
13627 * configure: Regenerate with self.
13629 2002-08-30 Kevin Ryde <user42@zip.com.au>
13631 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
13634 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
13636 * bin/autom4te.in (Request::load): Correctly test for "do" read
13639 2002-08-29 Akim Demaille <akim@epita.fr>
13641 * lib/Autom4te/General.pm (&xqx): New.
13642 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
13643 hand, which is not portable.
13645 * bin/autom4te.in: Use them.
13646 Use &error instead of die.
13647 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
13650 2002-08-17 Paul Eggert <eggert@twinsun.com>
13652 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
13653 default list of compilers to try, since it was long ago superseded
13654 by the ksh fc builtin. Suggested by Steven G. Johnson.
13656 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
13658 * doc/autoconf.texi (Invoking autom4te): End the option table,
13659 fixing a bug introduced by the previous patch.
13660 (Limitations of Make): Add a 'target lookup' subentry in the
13661 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
13663 2002-07-29 Mark D. Roth <roth@feep.net>
13665 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
13666 options and use $AUTOM4TE_PATH.
13667 * doc/autoconf.texi: Remove documentation of autom4te
13668 --include-envvar and --site-macro-subdir options and document
13669 use of $AUTOM4TE_PATH.
13670 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
13671 arguments from each language section.
13673 2002-07-29 Paul Eggert <eggert@twinsun.com>
13675 * doc/install.texi: Include copyright symbol in copyright notice.
13677 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
13679 (AM_MAKEINFOFLAGS): New macro.
13680 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
13681 * Makefile.am (INSTALL): Use the new macros.
13682 Use -o rather than --output, since "missing" does not grok --output.
13684 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
13686 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
13687 comments do not always work. Never trust the exit status of
13690 2002-07-24 Kevin Ryde <user42@zip.com.au>
13692 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
13693 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
13695 2002-07-23 Paul Eggert <eggert@twinsun.com>
13697 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
13698 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
13699 apparently treats PATH="nonexistent" as if it contained ".".
13700 Bug reported by Stefan `Sec' Zehl.
13702 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13704 * doc/autoconf.texi (Limitations of Make): Mention the special
13705 handling of the obj/ directory by BSD make.
13707 2002-07-20 Kevin Ryde <user42@zip.com.au>
13709 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
13712 2002-07-19 Akim Demaille <akim@epita.fr>
13714 * doc/autoconf.texi (Function Portability): `exit'.

13725 2002-07-18 Akim Demaille <akim@epita.fr>
13727 * config/config.guess, config/config.sub: Update.
13729 2002-07-18 Akim Demaille <akim@epita.fr>
13731 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
13734 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
13735 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
13736 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
13738 2002-07-18 Akim Demaille <akim@epita.fr>,
13739 Alexandre Duret-Lutz <duret_g@epita.fr>
13741 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
13742 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
13744 2002-07-17 Russ Allbery <rra@stanford.edu>

13826 2002-06-27 Paul Eggert <eggert@twinsun.com>
13828 * config/install-sh: Quote $src. Prefer || to test's -o option,
13829 as per "Limitations of Builtins".

13970 This improves on an earlier suggestion by H. Peter Anvin.
13972 2002-05-16 Paul Eggert <eggert@twinsun.com>
13974 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
13975 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
13976 Both macros now accept an optional source-dir arg.
13977 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
13979 * NEWS: Document this.
13980 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
13982 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
13983 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
13984 not for GNU extensions; this undoes part of the 2000-11-03 change,
13985 reverting to 2.13-compatible behavior.
13986 Add new optional argument DIR.
13987 (AC_FUNC_FNMATCH_GNU): New macro.

13991 2002-05-08 Paul Eggert <eggert@twinsun.com>
13993 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
13994 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
13995 and it causes a 'test' syntax error if it fails.
13996 Bug reported by Stephen Gildea.
13998 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
13999 If prototypes are supported, use them to check this at compile-time,
14000 instead of trying to check it at run-time. If we must do a run-time
14001 check, assume that setvbuf is standard when cross-compiling, as
14002 nonstandard setvbuf occurs only on ancient and unlikely hosts.
14003 Bug reported by Paul D. Smith.
14005 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
14006 argument specifying location of getloadavg.c. This removes a
14007 FIXME. This idea was taken from Jim Meyering's implementation in
14009 * doc/autoconf.texi (Particular Functions): Document this.
14010 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
14011 that's what the code does; this fixes a bug reported by
14014 2002-05-03 Akim Demaille <akim@epita.fr>
14016 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
14017 autopoint instead of gettextize.
14018 ($uses_alocal): Rename as...
14019 ($uses_aclocal): this.
14020 * doc/autoconf.texi (autoreconf Invocation): Adjust.
14021 Suggested by Bruno Haible.
14023 2002-05-03 Akim Demaille <akim@epita.fr>
14025 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
14027 2002-04-29 Paul Eggert <eggert@twinsun.com>
14029 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
14030 files to be 1 second older; just set them to be the same time.
14031 Also, sleep 1 second after the first aclocal, to work around
14032 problems with sub-second time stamps on the input files.
14034 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
14036 * doc/autoconf.texi: Mention "set -e -x" lossage
14037 under node "Limitations of Builtins".
14039 2002-04-29 Akim Demaille <akim@epita.fr>
14041 * doc/install.texi: Better wording for setting variables when
14043 From Christian Cornelssen.
14045 2002-04-29 Akim Demaille <akim@epita.fr>
14047 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
14048 of lack of $LINENO support, then the test will compare the $LINENO
14049 in testsuite vs. the lineno in the test file. This is wrong, of
14051 Be sure to protect it.
14052 Reported by Patrick Welche.
14054 2002-04-25 Akim Demaille <akim@epita.fr>
14056 * doc/autoconf.texi (Obsolete Macros): Typo.
14057 Reported by Vladimir Volovich.
14059 2002-04-25 Akim Demaille <akim@epita.fr>
14061 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
14062 than some of the input files, hence, on the second run of aclocal,
14063 if some of its input are younger, make them older.
14064 Suggested by Paul Eggert.
14066 2002-04-25 Akim Demaille <akim@epita.fr>
14068 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

14073 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
14074 and ac_subst_vars be sh variables containing the list of
14075 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
14077 (_AC_INIT_PREPARE): Use them to log them.
14078 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
14079 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
14080 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
14081 _AC_SUBST_FILES and _AC_SUBST_VARS.
14082 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
14084 2002-04-24 Akim Demaille <akim@epita.fr>
14086 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
14087 autoheader, so that automake does not complain about a missing
14088 config.h.in that was to be created.
14090 2002-04-23 Akim Demaille <akim@epita.fr>

14236 directories when descending in a SUBDIRS.
14237 Reported by Ezra Peisach.
14239 2002-04-04 Andreas Schwab <schwab@suse.de>
14241 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
14242 contains no literal separators.
14244 2002-04-03 Akim Demaille <akim@epita.fr>
14246 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
14247 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
14248 Use dnl, not the KILL diversion.
14250 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
14251 (AC_CONFIG_LINKS): here.
14253 Don't use the KILL diversion, as it kills spurious output, which
14254 results in failures being hidden.
14255 Use m4_defn where appropriate.
14256 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
14257 after the second argument.
14259 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
14260 syntax, as it is provided by M4sugar.

14266 expanded if $# <= 2.

14277 (_AC_COMPILER_OBJEXT): Use them.
14278 Fixes Debian #138666.
14280 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
14282 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
14284 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
14285 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
14286 (AC_PROG_CC): Call _AC_PROG_CC_STDC.

14288 (AC_C_CONST): Same.

14302 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
14303 to avoid versions of HP C which don't allow that.
14305 2002-03-27 Paul Eggert <eggert@twinsun.com>
14307 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
14308 (AS_SHELL_SANITIZE): Invoke it.

14319 2002-03-25 Paul Eggert <eggert@twinsun.com>
14321 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
14322 as POSIX requires, as it doesn't work with Zsh.
14323 * doc/autoconf.texi (Assignments): Document the problem.
14325 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

14333 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
14334 problem with here-document buffer boundaries.
14336 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
14337 when reinvoking the shell, to work around problems with installers
14338 who put strange things like "cd" commands in their environments.
14340 2002-03-19 Akim Demaille <akim@epita.fr>

14358 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

14362 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
14363 (Limitations of Usual Tools): Add mkdir section.
14365 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
14366 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
14367 back on AS_DIRNAME to compute prefixes otherwise; this is
14368 roughly what mkinstalldirs does. That way, we need not have
14369 our own filename disassembler. The old disassembler did not
14370 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
14372 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
14373 Create at_test_all by a series of assignments,
14374 not by a single assignment of a long string. The latter causes ksh
14375 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
14376 presumably because of a buffer overrun.
14378 2002-03-14 Paul Eggert <eggert@twinsun.com>
14380 * lib/autotest/general.m4 (at_times_skip):
14381 Renamed from at_times. Now a boolean.
14382 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
14383 says 'times: not found'.
14385 2002-03-14 Akim Demaille <akim@epita.fr>
14387 * bin/autoreconf.in (&study_gettextize): New.
14388 (&autoreconf): Handle newest gettextize.

14399 Add information about stdint.h and inttypes.h from Paul Eggert.
14401 2002-03-13 Akim Demaille <akim@epita.fr>

14412 2002-03-11 Andreas Schwab <schwab@suse.de>

14415 does not do it if --with-lispdir is given.

14424 subdirectory should exist.
14426 2002-03-08 Akim Demaille <akim@epita.fr>
14428 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
14430 2002-03-08 Akim Demaille <akim@epita.fr>
14432 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
14433 aliases the actual variables, and modifications of the former
14436 2002-03-08 Akim Demaille <akim@epita.fr>
14438 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
14439 because of C-c: have m4 output in tmp files, then mv them.
14441 2002-03-08 Akim Demaille <akim@epita.fr>

14462 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
14463 * lib/autoconf/general.m4 (AC_INIT): More informative error
14464 message for LIBOBJ.
14466 2002-03-04 Akim Demaille <akim@epita.fr>

14471 2002-03-04 Akim Demaille <akim@epita.fr>
14473 * doc/autoconf.texi (Transforming Names): Equality between target
14474 and host is irrelevant.
14475 (Specifying Names, Canonicalizing): Remove all references to the
14476 backward compatibility hooks. Rather, collect them all into...
14477 (Hosts and Cross-Compilation): this new section.
14478 * doc/install.texi (System Type): Ditto.
14479 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
14480 that `--host' implies cross-compilation.
14482 2002-03-04 Akim Demaille <akim@epita.fr>
14484 * doc/autoconf.texi (Evaluation Macros): New.
14485 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
14487 (_m4_foreach): Define the variant with immediate evaluation so
14488 that it contains exactly the items, not an expression which
14489 evaluation is the current item.
14490 (m4_re_string, m4_re_word): Don't over quote them.
14492 2002-03-04 Akim Demaille <akim@epita.fr>
14494 Instead of having stacking `shift's evaluated at the end, let
14495 `foreach' loops immediately evaluate them.
14497 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
14498 $*. This is the n-th time I change my mind, but hopefully this is
14501 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
14503 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
14504 it was only a hack for m4_text_wrap.
14505 (m4_car2): Remove, replaced by...
14507 (_m4_foreach): Adjust.
14508 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
14509 m4_bpatsubst for clarification.

14560 Fix Autoconf PR/207:
14561 AC_PREFIX_PROGRAM fails with dashed program names
14563 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

14626 Also, pass `--reload-state=' on them, so...
14627 (handle_m4): don't.
14628 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
14629 (M4sh): Rely on M4sugar.
14630 (Autotest, M4sh, M4sugar): Use frozen files.

14662 2002-01-28 Akim Demaille <akim@epita.fr>
14664 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
14667 2002-01-28 Akim Demaille <akim@epita.fr>
14669 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
14670 AUTOTEST_PATH *after* it was set.
14671 Don't put `.' in the PATH: the user should be precise and `./' if
14672 needed. In addition, given that the test suite does some `cd', if
14673 `.' is in the path, the `tested programs' sections will report
14674 programs found in the test suite's directory, while during the
14675 tests (performed in their own directory), these programs are no
14676 longer visible. In other words, the results is confusing and

14741 2002-01-06 Akim Demaille <akim@epita.fr>
14743 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
14744 package.m4, since is really depends upon configure.ac, not
14746 * doc/autoconf.texi (testsuite Scripts): Adjust.
14747 * tests/Makefile.am (package.m4): New.
14748 EXTRA_DIST it since its a source.
14750 2002-01-06 Akim Demaille <akim@epita.fr>
14752 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
14753 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
14754 and PACKAGE_BUGREPORT from here...
14755 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
14757 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
14758 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
14759 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
14760 * tests/tools.at (autoheader): Adjust.
14761 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
14763 2002-01-06 Akim Demaille <akim@epita.fr>

14767 2002-01-03 Akim Demaille <akim@epita.fr>
14769 * doc/autoconf.texi (Output): Improved wording regarding use of
14773 2001-12-18 Kevin Ryde <user42@zip.com.au>
14775 * doc/autoconf.texi (Function Portability): Add notes on sscanf
14776 sometimes needing writable input.
14778 2001-12-17 Jim Meyering <meyering@lucent.com>
14780 * doc/autoconf.texi (New Macros): Tweak wording.
14782 2001-12-14 Akim Demaille <akim@epita.fr>
14784 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
14785 trailing files, don't apply `-rf' to files which might not be
14786 created by configure (core, core.*, and *.core), but just `rm -f'.
14787 Suggested by Jonathan Kamens.
14789 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
14791 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
14793 2001-12-14 Akim Demaille <akim@epita.fr>
14795 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
14797 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
14799 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
14800 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
14801 abs_srcdir, top_srcpath to abs_top_srcdir.
14802 (_AC_OUTPUT_FILES): Adjust.
14803 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
14804 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
14805 * tests/wrappl.in, tests/wrapsh.in: Adjust.
14807 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
14809 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
14810 C/Fortran linking on HP/UX, by extracting the Fortran library
14811 search path from the LPATH line in the $F77 -v output.
14813 2001-12-12 Kevin Ryde <user42@zip.com.au>
14815 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
14816 forbidden file descriptors table.
14818 2001-11-26 Akim Demaille <akim@epita.fr>
14820 * bin/autoscan.in (%c_keywords): Build it at top level.
14821 Map to 1 in order to simplify its uses.
14823 2001-11-26 Akim Demaille <akim@epita.fr>
14825 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
14826 Remove $filepath, useless.
14827 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
14828 variables, they are really part of the tokens.
14829 Split the input line on spaces and then look for tokens.
14830 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
14831 because of `lex$U.$(OBJEXT)'.
14832 (&scan_files): Use "@list" instead of join.
14833 * doc/Makefile.am (CLEANFILES): Add *.fns.
14835 2001-11-26 Akim Demaille <akim@epita.fr>
14837 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
14838 Remove, replaced by...
14839 * tests/wrappl.in: Be common for all the Perl executables.
14840 In particular autoscan and autoheader want -I.
14841 * configure.ac: Adjust.
14842 * lib/autoscan/headers: errno.h is portable.
14844 2001-11-26 Akim Demaille <akim@epita.fr>
14846 * bin/autoscan.in (used): New.
14849 2001-11-26 Akim Demaille <akim@epita.fr>
14851 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
14853 (&scan_sh_file): Remove a duplicate pattern.
14854 (&check_configure_ac): Use long options.
14855 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
14857 2001-11-26 Akim Demaille <akim@epita.fr>
14859 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
14860 Before, having a line containing the opening of a multi line
14861 comment made the whole line be ignored.
14863 2001-11-26 Akim Demaille <akim@epita.fr>
14865 * doc/autoconf.texi (Using an Autotest Test Suite): New.
14866 (testsuite Scripts): Be one of its subsection.
14867 (Autotest Logs): New.
14869 2001-11-26 Akim Demaille <akim@epita.fr>
14871 Test groups are now run two directories deeper.
14873 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
14874 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
14876 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
14877 top_srcdir, builddir and top_builddir.
14878 Use `at_*dir' relatively to the directory containing the
14879 suite, use `*dir' when relatively to the current group dir.
14881 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
14883 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
14884 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
14885 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
14888 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
14890 * doc/autoconf.texi (Using System Type): Add an example of `case
14891 $host' usage so people quit using `case $target' everywhere.
14893 2001-11-22 Akim Demaille <akim@epita.fr>
14895 * doc/autoconf.texi (Installation Directory Variables): Englishoes
14896 spotted by Jim Meyering.
14898 2001-11-16 Paul Eggert <eggert@twinsun.com>
14900 This patch implements a `long double' suggestion by Oliver Kiddle.
14902 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
14903 static, to catch errors if the value isn't known at compile-time
14904 and the compiler supports dynamic arrays. Change its name from
14905 `_array_' to `test_array' to avoid potential name clashes.
14906 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
14907 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
14908 better than double. Catch a bug in GCC 2.95.2 x86.
14909 * doc/autoconf.texi (C Compiler): Document the above.
14912 2001-11-13 Akim Demaille <akim@epita.fr>
14914 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
14916 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
14918 2001-11-13 Akim Demaille <akim@epita.fr>
14920 * lib/autotest/general.m4 (AT_INIT): After having run the test
14921 group, go back to the initial directory, not to at_suite_dir.
14923 2001-11-13 Akim Demaille <akim@epita.fr>
14925 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
14926 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
14927 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
14929 (AT_CHECK_CONFIGURE): Use absolute paths.
14930 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
14931 The problem is still the old one: there is no means in M4 (that I
14932 know about) to create a defining macro, because there is no means
14933 to create `$1' etc., therefore, the defining macro ``swallows''
14934 all the arguments meant to the defined macro.
14936 2001-11-13 Akim Demaille <akim@epita.fr>
14938 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
14939 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
14941 * tests/aclocal.m4: Remove, as it is no longer used.
14943 2001-11-13 Akim Demaille <akim@epita.fr>
14945 * lib/autotest/general.m4: Change `tests?' into `groups?' in
14946 variable names when referring to a single test group, or to
14947 `suite' when referring to the whole test suite.
14948 `at_last_test' is removed: m4 compute at_format itself.
14949 (at_stdout, at_stder1, at_stderr): New variables.
14950 (AT_CHECK): Use them.
14952 2001-11-13 Akim Demaille <akim@epita.fr>
14954 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
14956 Create `testsuite.dir/003/run' instead of `testsuite.003'.
14957 Do it as soon as a test fails, don't wait till the end of the test
14959 Don't remove $as_me.[0-9]*, since these files no longer exist.
14961 2001-11-13 Akim Demaille <akim@epita.fr>
14963 * tests/tools.at: Use absolute paths, since we are no longer run
14966 2001-11-13 Akim Demaille <akim@epita.fr>
14968 Now that tests are running in their own private dir, there is no
14969 need to list the files to remove at the end of tests groups.
14971 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
14972 (AT_data_files, at_data_files): Remove.
14973 (AT_CLEANUP, AT_DATA): Simplify.
14975 Remove the group dir if !debug && !failed.
14976 * tests/atspecific.m4: Adjust.
14978 2001-11-13 Akim Demaille <akim@epita.fr>
14980 Start a new layout for Autotest: `testsuite' creates
14981 `testsuite.dir' in which the at-check-line etc. files are to be
14982 found, and `testsuite.dir/003' where the test group 3 is run.
14984 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
14985 at_check_line_file, at_format, at_test_normalized, at_group_dir
14987 Create the directories.
14988 Use absolute paths for at- files.
14989 (AT_CHECK): Adjust.
14991 2001-11-11 Michael Matz <matz@kde.org>
14993 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
14995 (m4_car): Properly quote arguments.
14997 2001-11-13 Akim Demaille <akim@epita.fr>
14999 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
15000 with stricter rules on LIBOBJS.
15002 2001-11-12 Paul Eggert <eggert@twinsun.com>
15004 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
15005 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
15008 2001-11-12 Akim Demaille <akim@epita.fr>
15010 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
15012 2001-11-12 Akim Demaille <akim@epita.fr>
15014 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
15015 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
15016 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
15017 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
15018 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
15019 specify to what the macro should be defined (typically to 1).
15021 2001-11-12 Akim Demaille <akim@epita.fr>
15023 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
15026 2001-11-12 Akim Demaille <akim@epita.fr>
15028 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
15029 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
15030 definition used by Automake where LEX is +/- "${missing} lex" and
15031 `missing' itself contains variables.
15033 2001-11-12 Akim Demaille <akim@epita.fr>
15035 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
15036 Now that M4sh pushes BODY, the comments were output at the end of
15039 2001-11-08 Akim Demaille <akim@epita.fr>
15041 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
15042 that we can trace macros from aclocal.m4.
15043 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
15044 obsoleted, and redirect to the former anyway.
15045 Reported by Ralf Corsepius.
15047 2001-11-08 Akim Demaille <akim@epita.fr>
15049 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
15050 processed only if present.
15051 * tests/torture.at (Configuring subdirectories): Use autoreconf
15052 instead of successive calls to autoconf.
15053 Add a nonexistent subdirectory to exercise the patch above.
15054 Reported by Ralf Corsepius.
15056 2001-11-08 Kevin Ryde <user42@zip.com.au>
15058 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
15059 doesn't accept .S files.
15061 2001-11-07 Akim Demaille <akim@epita.fr>
15063 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
15064 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
15065 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
15066 * bin/autom4te.in (warn_forbidden): New.
15067 (handle_output): Use it.
15068 Read m4_pattern_forbid with messages.
15070 2001-11-05 Akim Demaille <akim@epita.fr>
15072 * bin/autom4te.in (--normalize): Remove.
15073 * lib/autom4te.in: Adjust.
15075 2001-11-05 Akim Demaille <akim@epita.fr>
15077 * tests/Makefile.am (testsuite): Rename this target as...
15078 ($(TESTSUITE)): this.
15081 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
15083 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
15084 the --prefix option, also remove it's argument.
15086 2001-11-05 Akim Demaille <akim@epita.fr>
15088 * doc/autoconf.texi (testsuite Invocation): Update.
15089 (Writing testsuite.at): Update.
15091 2001-11-03 Akim Demaille <akim@epita.fr>
15093 * doc/autoconf.texi: s/@code/@command/ where appropriate.
15095 2001-11-03 Akim Demaille <akim@epita.fr>
15097 * lib/Autom4te/General.pm: (&catfile, &canonfile)
15098 (&file_name_is_absolute): New, wrappers around routines from
15100 Use and export them.
15101 (&find_configure_ac): Optionally take a directory where to look at.
15102 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
15104 Default @ARGV to `.', not find_configure_ac.
15105 (&autoreconf): Argument is a directory.
15106 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
15107 * doc/autoconf.texi (autoreconf Invocation): Update.
15109 2001-11-03 Akim Demaille <akim@epita.fr>
15111 * lib/Autom4te/General.pm (@export_vars, @export_subs)
15112 (@export_forward_subs): New.
15113 Add basename, dirname, and fileparse.
15115 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
15116 Don't look for aclocal flags if we already know aclocal is not
15118 Move aclocal.m4t only if it exists.
15119 Reported by Ezra Peisach.
15121 2001-11-03 Akim Demaille <akim@epita.fr>
15123 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
15124 passed on command line, defaulting to ./configure.ac if present.
15125 (&maybe_autoreconf, File::Find): Remove, unused.
15126 (&autoreconf): If autoconf is not used, don't try to trace.
15128 2001-11-02 Akim Demaille <akim@epita.fr>
15130 * configure.ac: Bump to 2.52g.
15132 2001-11-02 Akim Demaille <akim@epita.fr>
15136 2001-11-02 Akim Demaille <akim@epita.fr>
15138 * config/config.guess, config/config.sub, doc/standards.texi:
15139 * config/lispdir.m4: Update from masters.
15140 * configure.ac: Bump to 2.52f.
15142 2001-11-02 Akim Demaille <akim@epita.fr>
15144 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
15145 Don't run aclocal when aclocal.m4 is not from aclocal.
15147 Don't run libtoolize and gettextize if --install is not given.
15149 2001-11-01 Paul Eggert <eggert@twinsun.com>
15151 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
15152 be invoked before _AS_LINENO_PREPARE.
15153 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
15154 than character ranges.
15156 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
15157 invoking AS_BASENAME. Set the locale variables to 'C' if
15158 possible, as POSIX requires this to get the traditional
15160 * doc/autoconf.texi (Special Shell Variables): Describe the above.
15162 2001-10-31 Paul Eggert <eggert@twinsun.com>
15164 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
15165 with {}, as that triggers a bug in Bash 2.05.
15167 (_AS_LINENO_PREPARE): Use Sed rather than
15168 Awk. Fix the sed prepass to work even if there are multiple
15169 instances of $LINENO on the same line. Do not substitute for
15170 other variables like $LINENOT. Do not check file dates; such a
15171 check is unreliable on sufficiently fast machines, and removing
15172 the check makes the code simpler and more reliable. Check for
15173 output and chmod failures.
15175 * doc/autoconf.texi (Special Shell Variables): Document
15178 2001-10-31 Akim Demaille <akim@epita.fr>
15180 * tests/Makefile.am (atconfig): Remove this target, Automake
15183 2001-10-31 Akim Demaille <akim@epita.fr>
15185 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
15186 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
15187 provided, while it is optional.
15188 * configure.ac: Adjust.
15190 2001-10-26 Paul Eggert <eggert@twinsun.com>
15192 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
15193 lib/Autom4te/Struct.pm:
15194 Require Perl 5.005_03 instead of just 5.005, as some tests fail
15197 * doc/autoconf.texi (Special Shell Variables): Document some
15198 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
15200 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
15201 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
15202 eval $LINENO is not portable in practice.
15204 2001-10-24 Akim Demaille <akim@epita.fr>
15206 * lib/Autom4te/General.pm (backname): New.
15208 2001-10-24 Akim Demaille <akim@epita.fr>
15210 * m4/: Remove, merged into...
15213 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
15215 * doc/autoconf.texi (Shellology): Mention the problems with bash
15216 2.05's use of ANSI quoting in its `set' builtin.
15218 2001-10-22 Paul Eggert <eggert@twinsun.com>
15220 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
15221 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
15222 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
15223 POSIX decided to standardize on the int flavor of strerror_r.
15224 Always do char* test, as there's no reason not to.
15225 Assign to a char* var, to catch strerror_r that returns int*.
15227 * doc/autoconf.texi (Particular Functions):

15722 be used instead of ':'.
15723 * lib/autotest/general.m4: Replace occurrences of ':' in
15724 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
15726 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

15729 arguments. Fixed a typo.
15731 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
15733 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
15734 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
15736 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
15738 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

15751 2001-09-19 Akim Demaille <akim@epita.fr>
15753 * lib/autotest/general.m4: Englishoes.
15754 From Tim Van Holder and Alexey Mahotkin.
15756 2001-09-18 Paul Eggert <eggert@twinsun.com>
15758 * doc/autoconf.texi (Common Shell Constructs): New node,
15759 documenting AS_DIRNAME.
15760 (Limitations of Usual Tools): Refer to it when discussing dirname.
15761 Also, update discussion of POSIX standard to reflect latest draft.
15763 * lib/autoconf/c.m4:
15764 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
15766 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
15767 Do not pass a first argument with leading '-'
15768 to expr, by parenthesizing initial integers that might be negative.
15770 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
15771 now merely checks whether it is an error to pass an argument
15774 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
15775 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
15776 whether it is a (compile-time) error to pass an argument to
15777 getpgrp. This simpler test supports the revised documentation,
15778 and is all that AC_FUNC_GETPGRP's users really need.
15780 2001-09-18 Akim Demaille <akim@epita.fr>
15782 * doc/autoconf.texi (Limitations of Make) <$<>: New.

15792 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
15794 Add test for AS_BASENAME.
15795 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
15796 added test. It now correctly handles /1/2/3/, returning '3' not ''.
15797 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
15798 * tests/base.at: Fixed the expected responses. The old ones were
15800 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
15801 the documentation claims it should (and how it behaved in 2.13).
15803 2001-09-18 Akim Demaille <akim@epita.fr>
15805 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
15806 the AC_CONFIG_COMMANDS invocation.
15807 This also solves the name clash problems.
15808 Don't set the package's ID.
15809 * lib/m4sugar/Makefile.am (version.m4): Revamp.
15810 No longer to be shipped.
15811 (version.in): Remove.
15812 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
15813 * lib/autoconf/status.m4: Adjust.
15814 Use `m4_PACKAGE_STRING'.
15815 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
15816 the only optional argument is the name of the test suite.
15817 Expect `package.m4' to define the package signature.
15818 * lib/autom4te.in (Autotest): Add `package.m4?'.
15819 * tests/Makefile.am (package.m4): New.
15820 * tests/suite.at: ifnames is a victim.
15822 2001-09-18 Akim Demaille <akim@epita.fr>
15824 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
15825 AC_LIBSOURCE, AC_CONFIG_FILES.
15826 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
15827 program version string doesn't match the package's.
15828 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

15833 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
15834 Allow expression to return any value that can fit into unsigned long
15835 (not int, as before). Check for output errors.

15839 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
15840 Always include <stdio.h> and <stdlib.h>. Evaluate
15841 the expression in an extra function before these includes. Call
15842 fprintf "%d" only after ensuring the argument is of type 'int'.
15843 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
15845 2001-09-17 Paul Eggert <eggert@twinsun.com>
15847 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
15848 or CFLAGS=-O5. In that case, the linker has a relaxed view of
15849 fatal errors, and AC_CHECK_LIB causes it to include libraries even
15850 when they don't exist.
15852 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
15853 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
15856 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
15857 version with the version used by fileutils 4.1, except use
15858 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
15861 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
15863 2001-09-13 Akim Demaille <akim@epita.fr>

15903 * lib/autotest/general.m4 (AT_INIT): Create and remove
15904 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
15905 test suites can cohabit.
15907 2001-09-13 Akim Demaille <akim@epita.fr>
15909 * tests/mktests.sh: Don't output banners for empty test files.

16018 the maintainer is dumb enough to do that...
16020 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
16021 excellence in M4 quotation: consider `__file__' is active.
16023 And BTW, when invoking m4, pass the --include in the right order:

16171 * bin/autoconf.in (--include, -I): New option.
16172 Map --localdir, --autoconf-dir onto it.
16173 Forward autom4te's options instead of interpreting them.
16174 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
16175 There is no such envvar since the inception of autom4te.cfg.
16176 * bin/autom4te.in (&parse_args): Uniquify `@include'.
16177 * bin/autoupdate.in: Adjust, and perform more control.
16178 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
16179 * tests/autoconf: Dittowise.
16181 2001-08-31 Akim Demaille <akim@epita.fr>
16183 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
16184 * bin/autom4te.in (&find_file): Support `FILE?' standing for
16186 Use -e, not -f, since /dev/null for instance is OK.
16187 (&parse_args): Adjust.
16188 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
16190 2001-08-31 Akim Demaille <akim@epita.fr>

16195 installed peer executables, only PATH is allowed to resolve it.

16197 * lib/Autom4te/General.pm (&find_peer): Remove.
16198 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
16199 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
16200 * man/Makefile.am: Let help2man rely on PATH instead of trying to
16201 find the executables for it.
16202 * tests/Makefile.am: Major cleanup. Too lazy to document...
16203 * tests/atlocal.in: Remove all the obscure envvar manipulations.
16205 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
16206 indeed related to running the test suite, while passing
16207 --autoconf-dir and others is related to running non installed
16208 Autoconf executables. So don't do that, leave it to...
16209 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
16210 * tests/autoscan: New.
16211 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

16228 Suggested by Paul Eggert.
16230 2001-08-29 Akim Demaille <akim@epita.fr>

16233 download in a tmp dir.
16235 2001-08-29 Akim Demaille <akim@epita.fr>

16499 `Autoconf', not `autoconf' (the executable).

16619 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
16620 `$0.log' as for projects where testsuite is in src, we'd have

16637 * doc/autoconf.texi: Work around Texinfo buglets.
16638 (Transformation Rules): One example is enough, users are expected

16687 2001-08-15 Akim Demaille <akim@epita.fr>
16689 * Makefile.maint (CVS): New.
16690 (local-check): Run changelog-check. last.

16692 (cvs-dist): depends upon it.
16694 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
16696 * tests/Makefile.am: Use a clean-local rule to remove
16697 autom4te.cache (it's a directory, not a file.
16698 * Makefile.am: Ditto (but maintainer-clean-local).
16700 2001-08-15 Akim Demaille <akim@epita.fr>
16702 * bin/autom4te.in (@m4_warning): New.
16703 (&handle_m4): Use it.
16704 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
16705 warnings are issued at each run.
16706 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
16707 is in the src tree.
16709 2001-08-15 Akim Demaille <akim@epita.fr>
16711 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
16712 don't waste time running `autoupdate --version' works.
16713 * tests/tools.at (autoupdating AC_PREREQ): Likewise.

16783 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
16784 magic values from an object file when cross-compiling.
16785 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
16787 2001-08-10 Akim Demaille <akim@epita.fr>
16789 * bin/autom4te.in (&handle_output): Don't use `grep' with side
16791 Suggested by Russ Allbery.
16793 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
16795 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
16796 current $prefix to the sub-configures.
16798 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
16800 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
16801 extension (needed on BeOS). Reported by Guido van Rossum.
16803 2001-08-09 Akim Demaille <akim@epita.fr>
16805 * bin/autom4te.in ($icache): Load it only if older than autom4te.
16807 2001-08-07 Akim Demaille <akim@epita.fr>
16809 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
16811 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
16812 No need to remove the files before and after the each test, before
16813 each test and at the end of the suite is enough.
16814 Display only the children `times', not the shell's.
16815 If the test failed or was skipped, at-times is not available.
16817 2001-08-07 Akim Demaille <akim@epita.fr>
16819 Always produce testsuite.log, including when there are no
16820 failures. This helps getting information on skipped tests, and
16821 duration of the tests. Err, implement the latter btw.
16823 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
16824 Dump information on the first run of each test.
16825 (AT_CLEANUP): Create `at-times' containing the duration of the
16828 2001-08-07 Akim Demaille <akim@epita.fr>
16830 The use of `dumpstat' revealed that `len' was used although it
16831 should not. m4_text_wrap was using it, but in the Autoconf world
16832 where it is legal. Hence (i) test M4sh in its own world, not
16833 Autoconf's, and (ii), ahem, fix the bug :)
16835 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
16836 does not like `' instead of [].
16837 (AT_INIT): Forbid `^_?AT_'.
16838 And don't output such tokens.
16839 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
16840 `script.as', and `autom4te.cache'.
16841 Remove `empty' and `macro' which are no longer used.
16842 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
16843 * tests/m4sugar.at: Use it.
16844 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
16846 2001-08-07 Akim Demaille <akim@epita.fr>
16848 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
16850 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
16852 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
16854 2001-08-04 Akim Demaille <akim@epita.fr>
16856 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
16857 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
16859 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
16860 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
16861 (AC_F77_MAIN): Likewise.
16863 2001-08-04 Akim Demaille <akim@epita.fr>
16865 Don't rely on M4sugar outputting the patterns in files, since we
16866 might process the output _without_ running m4, hence without these
16869 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
16870 * bin/autom4te.in (@Request::includes): Remove, unused.
16871 (@Request::source): Rename as...
16872 (@Request::input): this.
16873 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
16874 (&handle_output): Fetch the patterns from the traces.
16875 `$forbidden' and `$allowed' are constant: use m//o.
16876 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
16877 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
16879 2001-08-04 Akim Demaille <akim@epita.fr>
16881 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
16882 autoconf', i.e., in addition to caching traces, cache the output.
16884 * bin/autom4te.in (Request::cache): Rename as...
16885 (Request::id): this.
16886 ($cache, $icache, $tcache, $ocache): New.
16887 (&handle_m4): Save M4 output in the cache instead of $tmp.
16888 (&handle_output): Adjust.
16889 (&up_to_date_p): Check that the output cache is up to date too.
16890 (top level): Run `&handle_m4' iff force or the cache is invalid.
16891 Run `&handle_output' if the output cache is more recent.
16893 2001-08-04 Akim Demaille <akim@epita.fr>
16895 * bin/autom4te.in ($force): New.
16896 (&parse_args, &print_usage): -f, --force is a new option.
16897 (&handle_output): CPP directives might have spaces after `#'.
16898 (&parse_args): The first file only can be frozen.
16900 2001-08-04 Akim Demaille <akim@epita.fr>
16902 Don't let autom4te compute the `include' traces several times:
16903 first check that the trace cache file is up to date, and then
16904 compare its timestamp with that of the output.
16906 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
16907 the preamble. Don't require 5.005 as Autom4te::General does it,
16908 and better yet (use `use', not `require'!).
16909 * lib/Autom4te/Struct.pm: Rename the last occurrences of
16910 Class::Struct as Autom4te::Struct.
16911 * lib/Autom4te/General.pm (File::stat): Use it.
16912 (&mtime): New, export it.
16913 * bin/autom4te.in: Use it.
16914 Declare `$req' is invalid if it is outdated.
16915 Don't declare it valid before saving it if something went wrong.
16917 2001-08-04 Akim Demaille <akim@epita.fr>
16919 Autom4te shall not encode Autoconf data, and preselecting traces
16920 must be proposed to the users.
16922 * bin/autom4te.in (@required_trace): Remove.
16924 (&parse_args, &print_usage): -p, --preselect is a new option.
16925 (&up_to_date_p): Adjust.
16926 * bin/autoconf.in: Preselect some Autoconf macros.
16928 2001-08-04 Akim Demaille <akim@epita.fr>
16930 * tests/tools.at (autoconf --trace: user macros): Check traces on
16931 macros invoked without arguments, and macros invoked with multiple

16936 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
16939 2001-08-03 Akim Demaille <akim@epita.fr>
16941 * bin/autoconf.in ($@): Work around the usual sh bug.
16944 2001-08-03 Akim Demaille <akim@epita.fr>
16946 Clean up the handling of the M4 builtins tracing exception.
16948 * bin/autom4te.in (Request::request): Don't complete M4 builtins
16950 (@m4_builtins): Rename as...
16951 (@m4_builtin): this.
16952 (%m4_builtin_alternate_name): New.
16953 (&parse_args): Complete the trace requests with alternate names.
16954 (&handle_traces): Hence no longer do it here.
16955 (&trace_requests): Remove, unused.

16959 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
16960 m4_if, and m4_wrap.
16962 2001-08-03 Akim Demaille <akim@epita.fr>
16964 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
16965 (m4_divert_pop): Dump the whole diversion stack when a diversion
16967 * bin/autom4te.in (&handle_output): Remember of the first
16968 occurrence of a possibly undefined macro, not the last.
16969 Complain about the possibly undefined macros in the same order as
16970 the appear in the output.
16971 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
16972 * tests/tools.at (autoconf: forbidden tokens, basic)
16973 (autoconf: forbidden tokens, exceptions): No longer sort
16974 autoconf's stderr, as it is now deterministic.
16975 Check that `dnl' is caught.
16977 2001-08-01 Akim Demaille <akim@epita.fr>
16979 * configure.ac: Bump to 2.52c.
16981 2001-08-01 Akim Demaille <akim@epita.fr>

16991 2001-08-01 Akim Demaille <akim@epita.fr>

16996 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
16997 `END', as `Autom4te::General::END' will be triggered.
16998 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
16999 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
17000 system to run `mv', `rm', and `cmp'.

17004 * lib/Autom4te/General.pm (&unique): New.
