588 BSD behavior on binary input.
590 Minor testsuite improvements.
591 * lib/autotest/general.m4 (AT_INIT) <PREPARE_TESTS>: Use fewer
592 forks when sanitizing PATH. Always output machine information,
593 not just when atconfig was located.
595 Add 'testsuite -C dir'.
596 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
598 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
600 <DEFAULTS>: Delay computation of variables based on $at_dir...
601 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
602 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
603 <PARSE_ARGS>: Parse new option.

611 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
613 * build-aux/config.guess, build-aux/config.sub,
614 build-aux/texinfo.tex: Sync from gnulib.
615 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
618 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
620 * doc/autoconf.texi (Particular Programs): Do not mention the
621 Autoconf version in which the AC_PROG_INSTALL change was done.
622 Suggested by Paul Eggert.
624 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
626 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
627 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
628 mode, we change to the source directory, also set $ac_pwd so we
629 do not go back to the build tree for the next config subdir.
630 * tests/torture.at (Deep Package): Extend test to contain two
631 config subdirs on the top level.
633 Fix parallel `maintainer-check'.
634 * Makefile.am (maintainer-check-tests): Depend on `all'.

638 (maintainer-check): Serialize the testsuite runs.
640 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'

662 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
664 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
665 check_SCRIPTS. Building the wrappers for `all' allows help2man
666 to use them for the manpages.
667 Report by Benoit Sigoure.
669 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
671 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

683 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
684 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
685 (m4_require): Use m4_do, not m4_join.
687 Fix some whitespace tests on cygwin.
688 * tests/tools.at (autom4te and whitespace in file names): Restore
689 font-lock. Create $TMPDIR before it might be used.
691 Fix spurious testsuite failure with M4 1.4.11.
692 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
695 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
696 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
697 (m4_require): Avoid extra macro calls.
699 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
701 * tests/torture.at (srcdir): Fix quoting.
703 Do not pass top_srcdir to configure scripts in testsuite.
704 * tests/autotest.at (srcdir propagation): Copy install-sh to
706 (my only test): Drop setting of `top_srcdir'.
707 * tests/base.at (Input/Output): Likewise.
708 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
709 config.guess, and config.sub to test source tree.
710 Drop AC_CONFIG_AUX_DIR setting.
711 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
712 * tests/torture.at (Substitute a 2000-byte string): Drop
713 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
714 (Substitute a newline, datarootdir workaround): Likewise.
715 (Define a newline): Adjust for linenumber changes in configure.ac.
716 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
718 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
719 if `pwd` contains whitespace.
721 Quote $abs_top_srcdir in tests.
722 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
723 * tests/tools.at (Syntax of the shell scripts): Likewise.
725 * tests/m4sh.at (LINENO): Quote $0.
727 Fix testsuite program wrapper for whitespace in `pwd`.
728 The problem here is that the usual mantra is that command
729 variables can contain arguments, thus we cannot just escape
730 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
731 $top_builddir/tests directory early in $PATH, so that the
732 wrappers are found by their plain name.
733 * tests/wrapper.as: Put $testdir early in $PATH.
734 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
736 Proper config.status --file/--header and $srcdir escaping.

742 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
744 Fix Autotest for whitespace in `pwd`.
745 * lib/autotest/general.m4 (AT_INIT)
746 <at_func_create_debugging_script, Driver Loop>:
748 * tests/autotest.at (whitespace in absolute testdir): New test.
750 * lib/autom4te.in: Quote @datadir@.
752 Proper file name escaping in Autoconf programs and Perl modules.
753 This includes escaping of characters special to the shell
754 as well as special to Perl, e.g., leading `<' or `>'.
755 For example, when $file starts with `>', `open ">$file"'
756 wrongly tries to append to a different file.
757 * bin/autoconf.as: Fix quoting for autom4te options.
758 * lib/Autom4te/General.pm (shell_quote): New function, taken
759 from coreutils, written by Jim Meyering.
761 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
763 * bin/autoreconf.in (parse_args): Likewise.
764 * bin/autoscan.in (main): Likewise.
765 * bin/autoupdate.in (main): Likewise.
766 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
767 * bin/ifnames.in: Likewise, XFile usage fixes.
768 * tests/tools.at (autom4te and whitespace in file names): Extend
769 test. Test twice, with special characters allowed on w32, and the
770 rest. Test leading and trailing whitespace, for `open_quote'.
771 (autotools and whitespace in file names): New, analogous test.
772 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
773 by Russ Allbery and Eric Blake.
776 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
777 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
778 * lib/Autom4te/FileUtils.pm (open_quote): New function.
779 (update_file, contents): Use it.
781 * Makefile.am (autom4te-update): Rewrite for git.
783 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
785 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
788 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
789 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
791 2007-12-04 Eric Blake <ebb9@byu.net>
793 Manually resync with gnulib, since 'make cvs-update' no longer works.
794 * build-aux/config.guess: New upstream version.
795 * build-aux/config.sub: Likewise.
797 When using older automake, don't downgrade build-aux/texinfo.tex.
798 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
799 * doc/Makefile.am (TEXINFO_TEX): Add.
801 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
803 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
804 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
805 #undef as this runs afoul of our new way of creating config.h.
806 Problem reported by Jim Meyering in
807 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
809 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
811 Fix autom4te for unusual characters in input file names.
812 * bin/autom4te.in (files_to_options): Quote active characters
814 * tests/tools.at (autom4te and white space in file names):
817 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
818 Document that Tru64 awk always splits $0.
820 2007-11-24 Stepan Kasal <kasal@ucw.cz>
822 * lib/autotest/general.m4 (AT_INIT): Do not extract the
823 `#AT_STOP_...' line at the end of each test.
825 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
827 * lib/autotest/general.m4 (AT_INIT): For awk line number
828 extraction script, ensure `$at_group' has a defined value
829 even for the empty set, and properly quote its usage inside
832 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
834 * doc/autoconf.texi (Shell Functions): New chapter. Document
835 IRIX sh $0 issue in functions, move content from ...
836 (Portable Shell): ... here.
837 (Shell Script Compiler): Note that shell functions are not
838 totally unportable any more.
840 2007-11-22 Stepan Kasal <kasal@ucw.cz>
841 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
843 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
844 extracting the line numbers of the last needed test.
846 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
848 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
851 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
853 Fix IRIX testsuite debugging failures: $0 in functions.
854 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
855 Do not use $0 inside a function, as IRIX sh will set that to the
856 function name rather than the script invocation name.
858 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
859 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
861 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
862 to extract test scripts.
863 (AT_INIT): Extract and cache test script line numbers.
865 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
867 * lib/autotest/general.m4: Revert 2007-11-15 patch and
868 subsequent fixups; the awk -> here-document conversion trashes
869 performance too much with AIX sh.
871 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
873 * tests/local.at: Do not test m4, perl with AT_TESTED.
875 Diagnose and guard against write errors dealing with config.status.
876 The general idea is this: all write failures from `configure'
877 writing `config.status' are indicated by $ac_write_error, which
878 is only checked at the end. This is safe because config.status
879 code is not executed before the file is complete. Other write
880 failures, be they inside config.status, or in sub shell/awk
881 scripts spawned from configure or config.status, typically need
882 earlier checking, as their results are used right afterwards.
883 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
884 before writing config.status, check afterwards.
885 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
886 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
887 Set `ac_write_error' for write failures to config.status. Barf
888 upon write failures to temporary files.
889 Adjust note about closing and reopening the here-document.
890 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
891 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
892 reopening the here-document.
893 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
894 Ensure `ac_write_error' does not escape into config.status.
895 Also, add a couple of code paths not yet exercised in the test
896 suite: a config file with input from stdin, and a config header
898 Suggestion for catching write errors by Bruno Haible.
900 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
902 Avoid error with Tru64 awk and testsuite lines with many words.
903 * lib/autotest/general.m4 (AT_INIT): In the awk script that
904 reads the testsuite, set the field separator to an unusual value,
905 in order to not run over the limit of 199 fields. Tru64 4.0D awk
906 even splits the input if $i, i>0, was never accessed in the script.
908 Revert 2007-10-17 change.
909 * TODO: Multiline args in config files and headers mean something
910 different and are not fixed, see
911 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
912 Report by Stepan Kasal.
914 * doc/autoconf.texi (Generic Programs): Fix typo.
916 2007-11-16 Stepan Kasal <kasal@ucw.cz>
918 AC_*_TOOL does not canonicalize the prefix
919 * doc/autoconf.texi (Generic Programs): Do not say that
920 the *_TOOL macros canonicalize, they simply use the `host_alias'.
922 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
924 Diagnose write errors in config.status instantiations.
925 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
926 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
928 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
929 Extend test to also check for some write error failures, using...
930 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
931 Report by Bruno Haible.
934 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
936 (_AT_CHECK): Use less indentation, to save space.
938 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
940 Add witness macro for @top_build_prefix@ substitution.
941 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
942 (_AC_OUTPUT_FILE): Mention it here.
944 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
945 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
947 * lib/autotest/general.m4 (at_func_test): Remove.
948 (AT_INIT): Pre-extract test groups into separate files.

950 Remove at-test-source files together with the $at_group_dir.
951 * tests/autotest.at (Long test source lines): New test.
953 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
955 Shell functions and variables may share a namespace.

959 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
961 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
964 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
966 * lib/autoconf/status.m4: Fix a couple of comment typos.
968 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
970 2007-11-13 Jim Meyering <meyering@redhat.com>
972 Clean up the rule to create "expr".
973 * tests/Makefile.am (expr): Don't redirect directly to target.
974 Redirect just once, not for each echo statement.
975 Use $@, not literal "expr".
977 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
979 Don't worry about preprocessor when testing long long.
980 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
981 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
982 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
983 These no longer check for preprocessor flaws.
984 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
985 Do not check for preprocessor flaws.
987 2007-11-13 Jim Meyering <meyering@redhat.com>
989 Adapt dependencies, now that a version change doesn't modify configure.ac
990 * GNUmakefile: Remove "make clean" kludge.
991 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
993 Don't redirect directly to target.
994 Use $@, not literal "version.m4".
996 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
998 * doc/autoconf.texi (Making testsuite Scripts): Document
999 ":;{" shorthand as in previous patch.
1001 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1003 * doc/autoconf.texi (Limitations of Builtins): Document problem
1004 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1006 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1007 Use ":;{" shorthand.
1008 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1010 2007-11-12 Jim Meyering <meyering@redhat.com>
1012 Add more non-srcdir build support.
1013 * GNUmakefile (dummy): Split a long line.
1014 Add -v option to autoreconf invocation.
1016 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1017 * GNUmakefile (dummy): Remove INSTALL.
1019 Remove racy commands to build scripts in bin/ and tests/.
1020 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1021 are guaranteed to be built, remove the rules that tried to build
1022 them. Before, with a parallel build, these rules could lead to
1023 two processes writing tests/wrapper.in concurrently.
1025 Build in man/ only *after* building in bin/ and tests/.
1026 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1027 in both bin/ and tests/.
1029 Accommodate non-srcdir build-from-checkout.
1030 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1031 Use git's --git-dir=$srcdir/.git option.
1032 Add quotes, in case tarball_version_file contains shell meta-characters.
1033 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1034 * configure.ac: Pass "." to git-version-gen.
1036 Avoid spurious test failures due to version skew.
1037 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

1061 Document that $((expression)) is not portable.
1062 * doc/autoconf.texi (Shell Substitutions): Here.
1064 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1066 Ignore configure --help* errors due to LINENO-impaired shells.
1067 * tests/torture.at (Configuring subdirectories, Deep Package):
1068 In the --help* tests in read-only trees, make `.' temporarily
1069 writable again for the `stderr' file, and ignore errors due to
1070 the attempt to write configure.lineno.
1071 Report by Patrick Welche.
1073 2007-11-10 Jim Meyering <meyering@redhat.com>
1075 Generate package.m4 in build-dir, not srcdir.
1076 * tests/Makefile.am (package.m4): Adjust target.
1077 Don't redirect directly to $@.
1078 (CLEANFILES): Add package.m4.
1079 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1081 When running $(AUTOTEST), search "." before searching $(srcdir).
1083 Avoid a race condition that would make parallel "distclean" fail.
1084 * tests/Makefile.am (distclean-generic): Replace the default,
1085 automake-provided rule with an identical one, but with an additional
1086 dependency on distclean-local. Simply adding the dependency would
1087 cause automake not to emit the rule at all.
1088 * BUGS: Building with -jN works, now.
1090 Distribute git-version-gen.
1091 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1092 since GNUmakefile is distributed, and requires it for dist* rules.
1094 Remove two more generated files from version control.
1095 * INSTALL: Remove generated file.
1096 * lib/autoscan/autoscan.list: Remove generated file.
1098 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1100 * GNUmakefile (PATH): Remove stray apostrophes; they become
1101 part of PATH, which isn't wanted here.
1103 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1105 New config files output variable `top_build_prefix'.
1106 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1108 * doc/autoconf.texi (Preset Output Variables): Document it.
1110 Report by Bob Friesenhahn.
1112 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1113 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1114 function, to parametrize arithmetic with expr vs. the shell.
1115 Use it where possible.
1116 Suggestion by Benoit Sigoure.
1118 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1120 Adjust the documentation of autotest WRT atlocal.
1121 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1122 when using Automake, to write a rule to produce atlocal, since it's
1123 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1124 distributed, not atconfig.in.
1126 2007-11-04 Eric Blake <ebb9@byu.net>
1128 Update list information.
1129 * README: Mention new autoconf-commit list.

1136 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1138 * build-aux/.gitignore: Ignore mkinstalldirs.
1140 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1142 2007-11-03 Jim Meyering <meyering@redhat.com>
1144 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1145 * build-aux/git-version-gen: This syncs from coreutils.
1147 Adjust the build procedure so "make check" works reliably.
1148 * README-hacking: Include an extra step between "make" and
1149 "make check" to ensure that the latter passes.
1151 Use just-built tools, when possible.
1152 * GNUmakefile (PATH): Set and export here, ...
1153 (dummy): ... rather than here.
1155 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1156 and Andreas Schwab <schwab@suse.de>

1161 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1163 * configure.ac (AC_PREREQ): Require version 2.60, for
1164 AC_PROG_SED, AC_PROG_GREP.

1188 * build-aux/missing: Remove file.
1189 * build-aux/mdate-sh: Remove file.
1190 * build-aux/.gitignore: New file.
1191 Suggestion from Ralf Wildenhues.
1193 2007-11-03 Eric Blake <ebb9@byu.net>
1195 Adjust version comparison to account for git snapshot numbers.
1196 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a

1205 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1206 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1207 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1208 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1209 Suggested by Paul Eggert.
1211 2007-10-28 Jim Meyering <meyering@redhat.com>
1213 * README-hacking: Autoconf, Automake, and Perl are required to build.
1214 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1216 2007-10-28 Jim Meyering <meyering@redhat.com>
1218 README-hacking: Recommend running autoreconf -vi.
1219 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1220 so that we use just-built tools when they're available.
1221 Suggestions from Ralf Wildenhues.
1223 2007-10-28 Jim Meyering <meyering@redhat.com>
1225 Make inter-release --version output more useful.
1227 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1228 which indicates that it is built using the 19th change set
1229 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1230 is a prefix of the commit SHA1.
1231 * build-aux/git-version-gen: New file.
1232 * configure.ac: Run it to set the version.
1233 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1234 * Makefile.am (dist-hook): Arrange so that .version appears only
1235 in distribution tarballs, never in a checked-out repository.
1236 * .gitignore: Add .version here, too. Just in case.
1237 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1238 not configure.ac, now that the version number changes automatically.
1240 Ensure that $(VERSION) is up to date for dist-related targets.
1241 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1242 git-version-gen doesn't match $(VERSION), but only for dist targets.
1244 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1284 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1286 Don't check for bug in HP-UX 11.00 cpp.
1287 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
1288 Use -1ull rather than -1u, since that causes problems with gnulib; see
1289 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

1307 escaping of backslash in here-documents.
1309 Fix `Deep Package' test failure on FreeBSD.

1311 unnecessarily. Do not try running `/bin/sh configure' with a
1312 configure script to be found in $PATH, if the shell does not do
1313 this resolution. Fixes test failure on FreeBSD.
1315 Fix config header generation with AIX awk.
1316 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
1317 script, use helper array D_is_set, as `" 0"' does not evaluate

2540 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
2541 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
2542 works but the latter doesn't, then it's a valid type.
2543 This lets people use function types and so forth.
2544 For C++ there doesn't seem to be a simple solution, so leave it alone.
2545 (AC_CHECK_SIZEOF): Allow argument to be a variable.
2546 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
2547 AC_CHECK_TYPE; that wasn't documented or necessary.
2549 2007-04-11 Stepan Kasal <kasal@ucw.cz>
2551 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
2552 when cross-compiling.

2608 2007-03-09 Stepan Kasal <kasal@ucw.cz>
2610 * doc/autoconf.texi (Specifying Names): `--host' does not
2611 change the build type.
2613 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>

2631 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
2632 * doc/autoconf.texi (C Compiler): Document this. There is a new
2633 extra argument ACTION-IF-UNIVERSAL.
2634 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
2635 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
2636 Reindent for sanity's sake.
2638 2007-02-24 Eric Blake <ebb9@byu.net>
2640 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update

2649 status of rm so we know when it failed.
2650 If cleaning of test dir failed before running the test, warn.
2651 Output the line separator in verbose mode before the warning
2652 to make clear the warning belongs to the following test.

2717 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
2718 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
2719 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
2720 substitution will still be done by the special code.

2740 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
2742 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2744 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
2745 early on the reader side, drop stderr of the input to avoid
2746 `broken pipe' error output; this may happen even with shell
2747 builtin `echo' of some bash versions. Reports by Ian Macdonald
2748 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
2750 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2752 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

2762 Fix some wording problems noted by Paolo Bonzini in:
2763 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
2764 * doc/autoconf.texi (Signed Overflow Examples): Give more
2765 discussion about the allow_superuser_privileges example,
2766 and change it a bit to make things clearer.
2767 (Optimization and Wraparound): Clarify whether the compiler
2768 will generate an infinite loop for the example derived from
2769 Autoconf's mktime test.
2770 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
2771 Also, clarify unsigned multiplication overflow.
2773 2007-01-04 Eric Blake <ebb9@byu.net>
2775 * bin/Makefile.am (RELEASE_YEAR): New macro.
2776 (edit): Use it to supply correct copyright year to scripts.
2777 * bin/autoconf.as (version): Use it.
2778 * bin/autoheader.in ($version): Likewise.
2779 * bin/autom4te.in ($version): Likewise.
2780 * bin/autoreconf.in ($version): Likewise.
2781 * bin/autoscan.in ($version): Likewise.

2785 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
2787 * doc/autoconf.texi (Integer Overflow): Revised based on today's
2788 feedback. The most important changes document what happens when
2789 you convert an out-of-range value to a signed integer type, and
2790 say that (sum < a) != (b < 0) reliably detects overflow when sum =
2793 * doc/autoconf.texi (Integer Overflow): Greatly expand and
2794 rewrite, taking notions from the recent discussion on the gcc and
2795 autoconf mailing lists; please see
2796 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
2797 and follow the many links.
2798 (Integer Overflow Basics, Signed Overflow Examples):
2799 (Optimization and Wraparound, Signed Overflow Advice):
2800 (Signed Integer Division): New sections.
2802 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
2804 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
2805 preprocessor macro arguments in traced name.
2806 * doc/autoconf.texi (Defining symbols): Document longstanding
2807 support for AC_DEFINE-ing macros with arguments, and document
2808 behavior when the same variable has multiple AC_DEFINEs.
2809 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
2810 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
2811 macros directly, giving much shorter and simpler code.
2813 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
2815 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
2816 space before "$ac_configure_args" to prevent a 'config.status
2817 --recheck' failure if ac_configure_args doesn't contain a leading
2818 space. This works around a problem with the XEmacs configure.ac,
2819 which uses the (undocumented) ac_configure_args variable
2820 inconsistently with Autoconf.
2822 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
2824 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
2825 Include <limits.h>, and use its INT_MAX to rewrite the
2826 j loop so that it does not overflow 'int'. Problem reported by
2828 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
2829 Play it safe by shifting left by 1 rather than multiplying by 2,
2830 as GCC is less likely to optimize this away when the value
2831 is signed (when it assumes overflow leads to undefined behavior).
2832 Also, don't assume time_t uses two's complement.
2834 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2836 * tests/torture.at (Substitute a 2000-byte string): Avoid using
2837 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
2838 dumps core on it. Report by Tim Rice.
2840 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2842 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
2843 --disable-option-checking to --help output even when
2844 AC_PRESERVE_HELP_ORDER is not used.
2845 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
2846 --with argument, rather than argument with [-.] replaced by
2848 * NEWS: Fix typo in previous change; the news was in the
2851 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2853 * NEWS: Warnings are now generated by default for unknown
2854 --enable-* and --with-* options.
2855 * doc/autoconf.texi (Option Checking): Renamed from
2856 (Configure Option Checking). Tighten up the wording a bit.
2857 (External Software, Package Options): Cross-reference to Option
2858 Checking, and use this to shorten our section.
2859 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
2860 "$x" to test "x$foo" != x.
2861 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
2862 Don't warn if $enable_option_checking is "no".
2863 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
2864 ac_unrecognized_opts to the empty string.
2865 Don't echo the unrecognized opts, as this might mishandle
2866 backslashes or leading -.
2867 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
2868 usage next to the other --disable-FEATURE options in the
2871 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2873 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
2874 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
2875 Print warning for unrecognized --with and --enable options
2876 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
2877 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
2878 Disable option checking when subdirs are configured.
2879 (AC_OUTPUT): If warnings are enabled, print warning about
2880 unrecognized --with and --enable options at the end of
2881 the configure output (as well as at the beginning).
2882 * doc/autoconf.texi (Option Checking): New node.
2883 Document new option warning functionality.
2885 2006-12-16 Eric Blake <ebb9@byu.net>
2887 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
2888 * NEWS: Start news for current version.
2890 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
2892 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2893 Define HAVE_GETMNTENT to 1, not to the empty string.
2894 Problem originally reported by Jochen Friedrich in
2895 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
2897 This change prompted by a problem report by Andrey Simonenko in
2898 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
2899 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
2900 object-like macros only, in the traditional portable character
2902 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
2903 Warn about attempts to define things that are not identifiers.
2904 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
2905 awful hack that AC_DEFINEd macro names containing parentheses.
2907 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
2909 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
2910 too drastic, even if Texinfo in theory requires it for info mode.
2912 (config.status Invocation): Renamed back from Recreating a
2914 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
2915 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
2917 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2919 * NEWS: Version 2.61a.
2921 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2922 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2924 * NEWS: Document changes with echo and printf, and the lack
2925 of limits on the total size of multi-line values of substituted
2926 variables, and the AC_FUNC_FSEEKO fix.
2928 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
2930 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
2931 Writing configure.ac.
2932 (Autoconf Input Layout): Renamed from configure.ac Layout.
2933 (Recreating a Configuration): Renamed from config.status Invocation.
2934 (Obsolete Recreation): Renamed from Obsolete config.status Use.
2935 (acconfig Header): Renamed from acconfig.h.
2936 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
2937 (Writing Testsuites): Renamed from Writing testsuite.at.
2938 (Autom4te Cache): Renamed from autom4te.cache.
2940 * BUGS: Remove mention of VPATH problem, since it's now documented
2941 not to be a bug in the Autoconf build procedure itself, but rather
2942 a problem with the proprietary `make' programs.
2944 * doc/autoconf.texi (Build Directories): Add a cross reference
2947 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
2948 * doc/standards.texi: Sync from gnulib.
2950 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
2951 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
2952 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
2953 generated automatically.
2955 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
2957 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
2958 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
2959 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
2961 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2963 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
2964 `CEOF$ac_eof' special marker, the awk script cannot contain a
2965 line matching `^CEOF', so this is not needed any more.
2966 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
2967 special marker in the test.
2969 2006-12-06 Stepan Kasal <kasal@ucw.cz>
2971 * tests/tools.at (autom4te preselections): Use `find -newer';
2972 remove one of the sleeps.
2974 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
2975 more readable, using ...
2976 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
2978 * doc/autoconf.texi (autoheader Invocation): Do not double-
2979 quote the parameter of `AH_BOTTOM' in the example.
2981 2006-12-05 Stepan Kasal <kasal@ucw.cz>
2983 * doc/autoconf.texi (Configuration Headers): Remove the
2984 example with multiple input files.
2985 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
2986 multiple input files.
2988 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2990 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
2991 creating the awk substitution script, handle one input line at a
2992 time, so that the maximum length of a substituted (multi-line)
2993 value is not limited by the size of the sed pattern space.
2994 The trade-off is a slightly repetitive sed script.
2995 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
2996 can only have up to 7 characters, due to Solaris 10 /bin/sed.
2997 * tests/torture.at (Substitute a 2000-byte string): Increase the
2998 test with several long lines, they should not be caught by sed
3001 * tests/tools.at (autom4te preselections): New test, to flag
3002 entries missing from autom4te.cfg.
3003 Report by David Byron <dbyron@hheld.com>.
3005 * tests/torture.at (Substitute a 2000-byte string): Actually use
3006 AC_PROG_AWK, so the last change works as intended.
3007 (Substitute and define special characters): Likewise.
3008 (Substitute a newline): Likewise.
3010 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3011 instead of `awk' consistently.
3012 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3013 * tests/torture.at (Torturing config.status): Test both the
3014 result of AC_PROG_AWK and plain awk.
3015 (Substitute a 2000-byte string): Likewise.

3021 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3022 can be assigned to a function pointer. Problem reported by
3023 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3024 part of a patch by Ralf Wildenhues in that same bug report.
3026 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3028 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3029 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3031 2006-12-01 Eric Blake <ebb9@byu.net>
3033 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3034 cross-compiling from cygwin to mingw.
3035 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3036 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3037 to lib/autoconf/c.m4.
3039 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3041 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3042 string for more reliable failure. Wrap the entire test that
3043 causes the broken Solaris printf to dump core, in a subshell,
3044 so the segmentation fault message is reliably suppressed.
3045 Fix shell expansion errors by using /usr/ucb/echo always;
3046 avoid an error on systems without it by another subshell.
3047 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3048 subshell-$as_echo to `as_echo', for better error message.
3050 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3052 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3053 `BASH_SOURCE' contain a newline, set them to empty, as they may
3056 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3058 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3059 years and is too hard to maintain now. The last straw was
3060 reported by Jerker Baeck in
3061 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3062 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3063 * doc/autoconf.texi (Particular Functions): Move
3064 AC_FUNC_SETVBUF_REVERSED from here...
3065 (Obsolete Macros): ... to here. Say that it does nothing now.
3066 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3067 Turn into (almost) a no-op.
3069 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3071 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3072 These macros are obsolescent and new applications shouldn't need them.

3083 @VAR1@VAR2 has unspecified behavior. Problem reported by
3085 * NEWS: Mention this.
3087 * Makefile.am: Put only a single '#' into the copyright notice,
3088 so that it's also present in the output file. Standardize wording
3089 in makefile copyright notices to match GNU coding standards.

3103 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3105 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3106 in the sed script that mangles the awk script: delete up to the
3107 first exclamation mark only.
3108 * tests/torture.at (Substitute and define special characters):
3111 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3113 Rewrite config files generation: avoid quadratic growth in
3114 the number of substituted variables by using awk instead of sed
3115 for the bulk of the substitutions.
3116 * NEWS: Mention this.
3117 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3118 forbidden in the output (and thus input) file.
3119 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3120 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3121 generate just one large awk script for substitutions,
3122 eliminating much of the earlier complexity, while adding some
3123 new complexity. Only expand the substitution templates at
3124 configure time, for smaller configure script size. If
3125 _AC_SUBST_FILES are used, test 'awk' for working getline support
3126 at config.status time. If absent, interpolate through the
3127 shell. The awk script was written with much help
3128 from Paolo Bonzini and Paul Eggert.
3129 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3130 (_AC_SED_FRAG_NUM): Likewise.

3134 * tests/torture.at (Substitute a 2000-byte string): Also
3135 substitute a line with 1000 words, and a variable with several
3137 (Substitute and define special characters): Test awk special
3138 characters, and put substitution input strings `@foo@' in the
3139 output, to test that no recursion happens; test several other
3140 combinations from Paolo Bonzini.
3142 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3144 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3145 that replaced echo with AS_ECHO where this wasn't necessary.
3146 Problem reportd by Ralf Wildenhues.
3147 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3148 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3149 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3151 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3153 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3155 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3157 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3158 that traditional Awk lacks 3-arg "split". It has it.
3159 Mention that FS must be a single character, and a few other
3160 99-byte limits of traditional Awk.
3161 Mention that if (i in a) doesn't work with traditional Awk.

3167 (Newline-CODE-BS-newline in command):
3168 (Single-quote-BS-newline in command):
3169 (Single-quote-newline-BS-newline in command):
3170 Use printf '%s\n' instead of echo, for portability to hosts
3171 where echo interprets backslashes. This will break on hosts
3172 that lack printf, but for now let's assume all such hosts
3173 are dead (if not, we should get reports of test failures).
3175 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3177 'echo' has some portability problems, when given a first argument
3178 with a leading '-', or when given any argument containing '\'.
3179 Avoid using 'echo' in these cases.
3180 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

3208 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3209 Don't use ECHO_T, since ECHO_N is now reliable.
3210 * lib/autotest/general.m4 (AT_INIT): Likewise.
3211 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3212 rather than using a here-document to put the script into a file.

3215 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3216 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3217 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any

3224 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3225 Don't set as_nl, since _AS_ECHO_PREPARE does that now.

3227 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3228 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3229 Double-quote strings that would otherwise contain M4 comments.

3235 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3239 * configure.ac (AC_INIT): Bump to 2.61.

3243 Comment out for now, as this tests neither fails nor passes
3244 reliably. Problem reported by Ralf Wildenhues.

3359 and Stepan Kasal <kasal@ucw.cz>
3361 Handle special characters in test case titles correctly.
3362 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
3364 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
3365 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
3366 argument. Extend to check titles printed by ./micro-suite and
3367 ./micro-suite -l and the title in micro-suite.log.
3368 (Backquote in a test title,
3369 Single-quote in a test title,
3370 Double-quote in a test title): Don't expect failure anymore.
3371 (Backslash in a test title): Put a non-whitespace character after the
3372 backslash so that Bourne shells might actually see it as an escape
3374 (Brackets in a test title,
3375 Pound in a test title,
3376 Comma in a test title,

3392 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3394 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3395 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3396 5363) simply issues a warning when dividing by zero at compile
3397 time. Problem reported by Elias Pipping.
3399 2006-10-26 Eric Blake <ebb9@byu.net>
3402 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3403 show effect on macros that expand with commas.

3430 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3431 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3432 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3433 reported by Nelson H. F. Beebe for Coreutils 6.4.
3435 * tests/tools.at (autoconf --trace: user macros): Remove test
3436 for tracing multiline macros, since m4 1.4.7a uses a different
3437 way to number lines. Problem reported by Ralf Wildenhues.

3499 looking for special shell characters.

3515 (Imported from Automake.)
3516 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3517 which incorrectly sets the mode of an existing destination
3518 directory. In some cases the unpatched install-sh could do the
3519 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3520 system. We hope this is rare in practice, but it's clearly worth
3521 fixing. Problem reported by Alex Unleashed in
3522 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3523 Also, don't bother to check for -m bugs unless we're using -m;
3524 suggested by Stepan Kasal.

3575 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3577 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
3578 include the default headers, and redefine obstack_chunk_alloc
3579 and obstack_chunk_free. Fixes false failure with glibc.

3598 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
3600 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
3601 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
3602 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
3603 Use a better substitute, by inspecting the output of "ls"
3604 rather than just using ":".
3605 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
3606 rather than AS_EXECUTABLE_P, since we needn't worry about
3607 non-regular files here.
3609 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
3610 due to configuration hassles with this. See Tonya Underwood's report

3622 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
3623 initialization which is not inherited through the environment
3624 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
3625 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

3630 problems with mkdir -p -m.
3632 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
3634 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
3635 comment about ac_cpp_err; it was incorrect, and anyway
3636 ac_cpp_err is being removed below.
3637 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
3638 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
3639 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
3641 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
3642 with werror_flag and conftest.err and so forth. This is more
3643 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
3644 and anyway the user shouldn't normally want to see this gorp logged.
3645 Problem reported by Ralf Wildenhues.
3646 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
3647 empty, not 'no', since the rest of the code uses 'test -z'.
3649 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
3651 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3652 Use a single call to AC_DO_TOKENS rather than multiple, for
3654 (_AC_LINK_IFELSE): Test that resulting file is executable.
3655 Problem reported by mwoehlke in
3656 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
3658 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
3659 than creating a file to use with test -x; this is much faster.
3661 2006-10-02 Bruno Haible <bruno@clisp.org>
3663 * lib/autom4te.in (Automake-preselections): Add
3664 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
3666 2006-09-27 Stepan Kasal <kasal@ucw.cz>
3668 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
3669 standard error, `experr' should be used, not `expout'.

3673 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
3674 fseeko testing program twice; just use the earlier result.
3675 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3676 Set cache var to 'unknown' (not 'no') if leaving the macro unset
3677 still doesn't let the program compile.
3678 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
3681 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
3682 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
3683 include it, without including anything else.
3684 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
3686 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

3690 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
3691 `error.h', and include it, for a `error_at_line' prototype.
3692 Use a nonempty format string in the link test.
3693 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
3694 for a declaration of wait3.

3699 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
3700 can apply to constants too, and that it checks for macro defns.
3701 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
3702 and simply cast the identifier to void. This handles structure
3703 values. Problem reported by Ralf Wildenhues.

3918 broken lex libraries like native ia64-hp-hpux11.22; see
3919 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

4048 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
4049 -Wundef -Werror". Problem reported by David Fang in

4110 less skeptical about "volatile", after discussion with
4111 Bruno Haible on bug-gnulib.

4117 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
4118 compiler complains about it, even if things works after the
4119 complaint. Problem reported by Peter O'Gorman.

4122 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.

4125 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
4127 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

4140 under AC_C_VOLATILE.
4141 (Volatile Objects): Be a little less skeptical about what
4142 "volatile" means. Derived from thoughts by Ben Pfaff in
4143 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
4145 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4149 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4151 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4152 more globally, since the 2006-06-30 patch didn't suffice. Problem
4153 reported by Keith Marshall. Also, don't bother with builddir2,
4154 since it shouldn't be needed any more.
4156 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

4175 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4177 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4178 Require that long long int be at least 64 bits wide. C99 requires
4179 this and enough programs depend on it so we should check for it.
4180 Bruno Haible reports in
4181 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4182 that long long int is 32 bits wide with some nonstandard compilers.

4185 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4187 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4188 to a nonexistent file, so that we don't have to worry about
4189 a local site configuration that doesn't use /usr/local.
4190 Problem reported by Keith Marshall in
4191 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4193 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4195 * doc/autoconf.texi: Be more consistent about using @acronym with
4196 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4197 quite right (it talked about "OSF/Tru64", even though the
4198 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4199 and it even mentioned "OSF 4"!) and at this point there's little
4200 reason to talk about OSF any more, since it died in 1994.
4201 (Specific Compiler Characteristics): Simplify example of
4202 negative-size array.
4203 (File Descriptors): Reorder to make the text flow better.
4204 Remove joke about "appreciate the various levels"; I didn't get it.
4205 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4206 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4207 (File Descriptors, Limitations of Usual Tools):
4208 Tone down the advice against renaming or removing open files.
4209 (Limitations of Usual Tools): Add a new section, on 'rm'.
4211 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4213 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4214 -lXt in LIBS, idea from Karsten Hopp; this was due since
4217 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4218 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4219 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4220 (which belong to Xt, not X itself). See Debian bug 327655.
4222 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4244 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4246 * doc/autoconf.texi (Changed Directory Variables): New node,
4247 to document the whole `datarootdir' business a bit better.
4249 * tests/torture.at (datarootdir workaround): Extend test.
4250 Prompted by report by Alexandre Julliard.
4252 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4254 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4255 when using default mode of IBM C 6 for AIX. Problem and two-line
4256 fix reported by Larry Jones.
4258 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4260 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4261 about literal '${datarootdir}' if a definition is found in the
4264 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4266 * NEWS: Use "M4" rather than "m4" when appropriate.
4267 Problem reported by Eric Blake.
4268 * doc/autoconf.texi: Likewise.
4269 Use @acronym around BSD, GCC, and GNU when appropriate.
4270 (Why GNU M4): Renamed from "Why GNU m4".
4271 (Redefined M4 Macros): Mention that Posix
4272 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4273 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4276 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4278 * bin/autom4te.in (handle_output): Do not forbid the empty
4280 * tests/tools.at (autoconf: the empty token): New test.
4282 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4284 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4285 calls, so that we do not care whether they are LIFO or FIFO;
4286 in the m4_wrap, do not check which diversion is the topmost
4287 one, just check that the stack is balanced at the end.
4288 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4289 base diversion forever--pop the previous diversion before
4290 opening the new one; consequently, remove the m4_wrap call.
4291 * lib/autotest/general.m4 (AT_INIT): Likewise.
4292 * tests/m4sugar.at: Do not use
4293 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

4296 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4298 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4299 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4300 Rework example of m4wrap token-pasting trouble so that it doesn't
4301 care whether it's LIFO or FIFO.
4302 Fix some "contrary to"s that are awkward in English.
4304 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4306 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4307 to `yes' instead of `int$1_t' if the type is found, for more
4308 consistent configure output (where $1 is the number of bits).
4309 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4310 Suggested by Bruno Haible.
4312 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4313 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4314 with system headers. Report by Bruno Haible.
4316 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4318 * config/config.guess, config/config.sub: Sync from upstream.
4320 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4321 in order to avoid picking up an older installed frozen m4sh.m4f.
4322 Besides an outdated shell startup, this could have been created
4323 by an earlier M4 version with incompatible frozen file format.
4325 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4327 * README: Recommend m4 1.4.4 instead of 1.4.3..
4328 * doc/autoconf.texi: Likewise.
4329 (Special Chars in Names): Say that $(.FOO) is portable, as
4330 suggested by Stepan Kasal.
4331 (Installation Directory Variables, Build Directories):
4332 (Automatic Remaking, Subdirectories, Fortran Compiler):
4333 (Making testsuite Scripts, Defining Directories):
4334 Quote variable usages better.
4335 (Making testsuite Scripts): Add clean-local rule to makefile
4336 snippet, by Eric Blake.
4337 (Installation Directory Variables): Fix table item font.
4338 Reword slightly to clarify. Generalize advice about
4339 not using special characters to include all file-related
4340 vars, not just VPATH.
4341 (Special Chars in Variables): Warn about special characters in
4343 (Assignments): Clarify default-value example as suggested by
4345 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4346 (Special Shell Variables): Note leading ./ or ../, as suggested
4348 (Limitations of Builtins): Under cd, warn about CDPATH.
4349 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4352 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4354 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4355 `@var', for texi2html.
4356 (Systemology): Some more word wrapping, for DVI output.
4357 (autom4te Invocation): The short option for `--melt' is `-M',
4360 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4362 * doc/autoconf.texi: More formatting and English tweaks,
4363 many suggested by Ralf Wildenhues.
4364 Reword to avoid "@code{...}'s" and the like, since it's ugly
4365 with Emacs info mode. discontents -> woes.
4366 Put a few "will"s back. time stamp -> timestamp.
4367 side-effect -> side effect.
4369 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4371 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4372 Warn about $@ not persisting. Problem reported by Julien Danjou in
4373 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4374 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4375 Mention other special chars, too.
4377 2006-06-14 Eric Blake <ebb9@byu.net>
4379 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4381 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4383 * doc/autoconf.texi: Some systematic minor improvements, as
4384 follows. Use "makefile" when talking about makefiles
4385 generally (which might be named "makefile" or "Makefile" or even
4386 "foo.mk"), "Makefile" when talking about a specific makefile
4387 called "Makefile". This unclutters the text from weird quotes
4388 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4389 values" rather than "@var{foo}s" and similar constructs containing
4390 "}s". Use "Make rules" rather than "Makefile rules". Minor
4391 English-language improvements. Change the prefix "sub-" to "sub"
4393 Put blank lines around examples more consistently.
4394 Avoid "rather" and "very" as intensifiers.
4395 Avoid "will" as an auxiliary.
4396 (Limitations of Make): Split this node into....
4397 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):

4403 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4404 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4405 New nodes, resulting from splitup of Limitations of Make.
4406 All cross-references changed. Raise the top node from
4407 a section to a chapter, and all subnodes accordingly.
4408 Redo the introductory wording to match the new organization.
4409 (Installation Directory Variables): Use an example that is
4410 closer to what Autoconf actually does. Mention that VPATH's
4411 value should not contain metacharacters or white space.
4412 (Fortran Compiler): Fix a VPATH bug in an example.
4413 (Leading _ in Macro Names): Mention that this problem is no longer
4414 of practical concern.
4415 (VPATH and Make): Reword the advice to make it clearer
4416 that Autoconf and Automake support VPATH in non-GNU make, but
4417 many packages have bugs in this area.
4418 ($< in Explicit Rules): Refer to Build Directories rather
4419 than using a (non-VPATH-safe) example.
4420 (Automatic Rule Rewriting): Mention the sort of disaster that
4421 can ensue with Solaris-style rule rewriting with VPATH.
4423 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4438 (Limitations of Usual Tools): Comment fix.
4439 Do not nest @samp just to point to other table items.
4440 (Writing testsuite.at) <AT_CHECK>: The second argument to
4441 `@dvar' is already @samp'ed.
4442 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4443 do not use @var in the second argument.

4522 * tests/local.at (AT_CHECK_M4): New macro, almost identical
4524 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
4526 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
4527 `expout' as the last parameter.
4528 * tests/tools.at: Adapt to the above change.
4530 2006-06-04 Stepan Kasal <kasal@ucw.cz>

4544 * NEWS: GNU make now recommended for VPATH builds.
4545 Mention that some macros are now documented to be obsolescent.
4546 * doc/autoconf.texi:
4547 Prefer "current" to "modern" to describe
4548 currently-used (albeit perhaps old-fashioned) hosts.
4549 Mention which ancient features no longer need to be worried about.
4550 setgid -> set-group-ID
4551 setuid -> set-user-ID (these are the Posix terms)
4552 Fix some misuses of "only".

4567 Omit longwinded and obsolescent discussion of cp -f.
4568 Modernize discussion of expr, ls.
4569 (Limitations of Make): Modernize discussion of VPATH builds.
4570 Mention $? as a workaround in some cases.
4571 * doc/install.texi (Basic Installation):
4572 Mention "./configure; make; make install" first. Be more
4573 specific about why this file is generic. Remove unnecessary
4574 parens. Remove misleading "only". Remove obsolete advice
4575 about csh. Don't say "configure" takes awhile; say it
4576 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
4577 and CC=c99 rather than CC=c89, as these are blessed by current
4578 Posix. Recommend GNU make if doing a VPATH build.
4580 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
4582 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for

4601 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
4603 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
4604 about quoting the case statement, just in case.

4606 was fixed in ksh93g; reported by Ralf Wildenhues.

4620 argument with leading hyphen. Problem reported by Paul Eggert.
4622 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4624 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
4625 about quoting ac_try: quote all of it, if any of it seems suspicious.
4626 This means we don't have to worry about ${ or sed any more.
4627 Also, double-quote the case statement, to work around misuses via
4628 underquoting as reported by Ralf Wildenhues in
4629 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.

4645 Problem reported by Ralf Wildenhues in
4646 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
4647 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
4648 pre-2006-05-26 definitions, but leave in the comments that
4649 these macros are dangerous and should not be used.
4650 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
4651 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
4652 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.

4656 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4658 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
4659 the use of 'tr', since this is our only use of 'tr'.
4661 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4662 and Paul Eggert <eggert@cs.ucla.edu>
4664 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

4667 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4669 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
4670 the output file in the `${datarootdir}' test.
4672 2005-05-28 Stepan Kasal <kasal@ucw.cz>
4673 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4675 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
4676 mention of `datarootdir' in the input file(s), but literal
4677 `${datarootdir}' in the output file, and we haven't warned yet,
4678 then warn as well: the user may have (erroneously) used
4679 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
4680 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
4681 * tests/torture.at (datarootdir workaround): Extend this test.

4687 * doc/autoconf.texi (autoheader Invocation): The first argument to
4688 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
4689 alternatives and clear up the language a bit.
4691 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
4693 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
4694 ac_config_guess, ac_config_sub, ac_configure.
4695 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4696 Fix typo that prevented an unnecessary space from being removed.
4697 Problems reported by Ralf Wildenhues in:
4698 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
4700 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4702 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
4703 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
4704 Don't use the term "thread-safe" to talk about mkdir race
4705 conditions, since the problem is more a process than a thread
4706 issue. Problem reported by Stepan Kasal in:
4707 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
4708 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
4709 the test for 'install' more closely. Look at MKDIR_P first.
4710 Look in the PATH, and at /opt/sfw/bin.
4711 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
4712 Don't bother to try mkdir -p, since we already check mkdir --version;
4713 just look at the version number. (There's no easy way to check
4714 for race-free implementations.)
4715 * tests/tools.at (autoconf: subdirectories): Adjust to above
4716 changes, since MKDIR_P now might end in "/mkdir -p".
4718 * doc/autoconf.texi (autoheader Invocation): Mention that the
4719 first arg of AC_DEFINE_UNQUOTED must be a literal.
4720 Problem reported by Ben Pfaff in
4721 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
4723 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
4724 * doc/autoconf.texi (Special Chars in Variables): New section.
4725 (Preset Output Variables): Warn about special chars in CPPFLAGS.
4726 (Installation Directory Variables): Quote $(datadir) better.
4727 (Limitations of Builtins): Describe some of eval's trickiness.
4729 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
4730 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
4731 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
4732 in front of every arg, not just trailing args. Quote apostrophes.
4733 (_AC_EVAL_ECHO): New macro.
4734 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
4735 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
4737 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
4738 exposed by quoting of eval argument. Put the command on line line
4740 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
4741 (_AC_PATH_X, AC_PATH_X): Quote more safely.
4742 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
4743 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
4744 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
4745 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
4746 Use eval more safely.
4747 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
4748 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
4750 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
4751 lines, exposed by quoting of eval argument.
4753 2006-05-26 Stepan Kasal <kasal@ucw.cz>
4754 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4756 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
4757 initialization of `ac_cv_exeext', do not override it if it was
4758 already set, unless it was set to `no', for compatibility with
4759 Autoconf-2.13, and comment this.
4760 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
4761 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
4762 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
4763 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
4764 Document that this test may be overridden by setting
4767 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4769 Revert these two patches:
4771 2006-04-06 Eric Blake <ebb9@byu.net>
4772 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4773 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4776 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4777 Clean up _AC_COMPILER_EXEEXT* macros.
4778 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4779 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4780 ac_file to the name of the default output file and call
4781 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4782 initial `rm' of the candidate files...
4783 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4784 the same list in subsequent `rm' calls, and for the temporary
4785 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4786 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4787 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4788 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4789 no longer needed) by libtool. Make it a cache check.
4790 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4791 copied here by mistake.
4792 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4793 _AC_COMPILER_EXEEXT.
4794 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
4795 _AC_COMPILER_OBJEXT directly.
4796 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

4803 2006-05-25 Noah Misch <noah@cs.caltech.edu>
4807 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
4808 ENOLCK. Only mention `make -j' when applicable. Only raise
4809 fatal errors when `make -j' is involved. Improve error message.
4811 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4813 * doc/autoconf.texi (Here-Documents): We now know more about
4814 the variable expansion in here documents bug.
4815 Thanks to Tim Rice and Stepan Kasal.
4817 * doc/autoconf.texi (Making testsuite Scripts): Add an example
4818 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
4820 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4822 * tests/autotest.at (Multiline command from M4 expansion):
4823 No failure to be expected if the shell quotes newlines in
4824 commands in the `set -x' output. Report by Tim Rice.
4827 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4829 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
4830 expansion in the here-documents used by config.status, as that
4831 runs afoul of the Korn shell version M-12/28/93d bug described in
4832 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
4833 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
4834 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
4836 2006-05-23 Jim Meyering <jim@meyering.net>

4844 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
4845 ac_dB slightly, to save bytes in the script.
4846 Max out at 50 lines, rather than 96; this is more likely
4847 (though not guaranteed) to avoid obscure 'sed' failures.
4849 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4851 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
4852 `tr -d -' as bad option argument. Work around this by deleting
4853 an unrelated character.
4854 Report by Tim Rice <tim@multitalents.net>.
4856 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
4857 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4858 Stepan Kasal <kasal@ucw.cz>
4860 * doc/autoconf.texi (Particular Programs): Do not promise that
4861 we always prefer the GNU version of the program, and that we
4862 search according to PATH; both rules can have exceptions.
4863 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
4864 AC_PROG_SED. Move descriptions of limitations
4865 to the Limitations of Usual Tools section.
4866 (Limitations of Usual Tools) <sed>: Mention script length
4867 limitations with Solaris /usr/ucb/sed.
4868 <grep>: Fix wording for empty alternative. Mention that -c and
4869 -l should not be combined, and that -E and -F should not be
4872 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4873 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4875 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
4876 limits in Solaris 8 /usr/ucb/sed by testing a long script.
4878 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4880 * doc/autoconf.texi (Defining Symbols): Literal parameter of
4881 AC_DEFINE is now passed to m4_pattern_allow.
4882 * NEWS: Mention that; likewise for AC_SUBST.
4883 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
4884 the parameter to m4_pattern_allow.
4885 * tests/tools.at: Add a check for that.
4887 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4889 * lib/autoconf/status.m4: Fix typos.
4891 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4893 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
4894 only the files that this macro generates.
4896 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4898 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
4899 the HP-UX sed limitation of 99 commands, labels do not count.
4900 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
4902 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
4904 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4906 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4907 Import the following fix from coreutils:
4909 2006-01-13 Jim Meyering <jim@meyering.net>
4911 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
4912 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
4913 not double-quote uses of that variable, to accommodate the rare
4914 case in which getmntent is available in none of the libraries
4915 checked. This happens at least on FreeBSD 5.0.
4917 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
4919 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
4920 ac_config_guess, ac_config_sub, and ac_configure, since evidently
4921 some other programs unwisely rely on these undocumented vars.
4922 But put in warning comments about them.
4923 Problem reported by Ralf Wildenhues in
4924 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
4925 * NEWS: Document that these variables are intended to go away.
4927 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4929 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
4930 and set the language to C++ (analogous to the equivalent Fortran
4933 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
4934 * doc/autoconf.texi (C++ Compiler): Document it.
4935 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
4938 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
4940 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
4941 that caused config.status to generate 100-command sed scripts; the
4942 portable limit is 99.
4944 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4946 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
4947 variable `ac_d' instead of `d' to avoid infringing namespace.
4948 Report by Ralf Menzel.
4950 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
4952 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
4953 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
4954 * tests/tools.at (autoconf: subdirectories): New test, taken from
4955 the corresponding problem report by Ralf Wildenhues in:
4956 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
4958 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
4959 Quote some uses of shell variables if they might suffer unexpected
4960 globbing. This doesn't fix all instances of quoting problems that
4961 I found, just the easy ones that look safe.
4962 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
4963 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
4964 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
4965 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
4966 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
4967 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
4968 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
4970 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
4971 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
4973 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4975 * bin/autoreconf.in ($help): Reword according to the manual.
4976 Suggested by Olly Betts.
4978 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
4979 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4981 * bin/autoreconf.in: Pass the directory argument to
4982 `require_configure_ac'. Fix comment.
4983 * tests/torture.at (Configuring subdirectories): Expose this.
4984 Reported by Olly Betts.
4986 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4988 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
4989 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
4990 Automake as follows:
4992 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
4993 `$configure_in' instead of `configure.in', to preserve
4994 directory component.
4996 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4998 * config/config.guess, config/config.sub, config/texinfo.tex,
4999 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5001 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5003 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5004 test for C99 conformance; (bool) 0.5 is an integer constant
5005 expression, but (bool) -0.5 is not. Problem reported by Fedor
5006 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5008 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5010 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5011 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5012 Warn about obsolete install-sh files. Remove stray sentence
5013 fragment and fix cross reference.
5014 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5015 install -d; this undoes the 2006-05-10 change.
5016 (MKDIR_P): Mark with AN_MAKEVAR.
5017 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5018 that we don't require $INSTALL to be thread-safe. Move comments
5019 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5020 of AC_PROG_INSTALL. Output a message saying that we're checking
5021 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5022 MKDIR_P instead of AC_SUBST.
5023 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5024 Special magic for MKDIR_P, too.
5025 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5027 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5029 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5031 Sync from Automake, as follows:
5033 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5034 * config/install-sh: Initialize IFS, so field splitting isn't
5036 * config/mkinstalldirs: Likewise.
5037 * config/missing: Remove superfluous quotes. Replace all uses of
5038 `[' by `test', for consistency, and for..
5039 * config/missing (sed_minuso, sed_output): New variables.
5040 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5041 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5042 Fixes `missing' to detect `--output' for help2man. Fixes
5043 PR automake/483. Report by Dennis J. Linse.
5044 (autom4te): Document in `missing --help'.
5046 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5048 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5049 * config/install-sh: Don't use 'path' to talk about file names,
5050 as per GNU coding standards. Close a race condition reported by Ralf
5051 Wildenhues and Stepan Kasal. There is still a race condition
5052 on hosts that predate Posix 1003.1-1992, but we can't help this.
5053 Don't mishandle weird characters like space on pre-Posix hosts.
5054 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5055 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5056 AC_PROG_MKDIR_P from AS_MKDIR_P.
5057 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5058 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5059 earlier editions are not (including Automake 1.8.3).
5060 Do not suggest mkinstalldirs for thread-safety.
5061 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5062 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5063 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5064 presence of special characters and race conditions.
5065 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5066 in Autoconf's name space.
5068 2006-05-10 Bruno Haible <bruno@clisp.org>
5069 and Paul Eggert <eggert@cs.ucla.edu>
5071 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5072 from Automake with minor changes.
5073 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5075 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5077 * config/install-sh: Update to Automake CVS version, as follows:
5078 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5079 * lib/install-sh: Simplify the expr implementation of dirname.
5080 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5081 * lib/install-sh: Handle --, and diagnose unknown options.
5083 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5085 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5086 `./autom4te' to create `./testsuite', since the `all' target
5087 will ensure its presence, but `installcheck' should not create
5088 the uninstalled wrappers.
5090 * tests/torture.at (Unusual Automake input files): Skip if we
5091 detect automake < 1.8.
5093 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5095 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5096 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5097 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5100 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5102 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5103 munge (multiple) white space and other oddities.
5104 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5105 single quotes in variable assignment.
5106 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5107 and similar failures by adding multiple spaces, tabs, and other
5109 Report and different test suggested by Francesco Romani
5110 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5112 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5113 single quotes, we only need to search for single quotes; this
5114 both simplifies the search pattern, and makes us less
5115 susceptible to `echo' variations for arguments not containing
5117 (_AC_ARG_VAR_VALIDATE): Likewise.
5119 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5121 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5122 `$*' and IFS concatenation issue with traditional shells and
5123 bash-2.04. Report by Seanster@Seanster.com.
5125 2006-05-03 Bruno Haible <bruno@clisp.org>
5127 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5128 precisely which Mac OS X versions have the od problem.
5130 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5132 * doc/autoconf.texi: Use @option systematically.
5134 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5135 and Bruno Haible <bruno@clisp.org>
5137 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5139 (Integer Overflow): Mention the special case of integer division
5142 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5144 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5145 traditional shells like the Solaris one that do not use the
5146 first IFS character for assembling `$*'.
5147 Prompted by a related report from autoconf_bug@nro.ca.
5149 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5150 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5152 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5153 Mention more problems with the -e option.
5155 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5158 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5160 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5161 in URLs to improve DVI formatted output (requires texinfo 4.6).
5162 (System Services, Systemology, Shellology): Likewise.
5163 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5166 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5168 (Runtime): Fix macro argument names to match description:
5169 `action-if-found' -> `action-if-true' and similarly.
5170 (Obsolete Macros): Likewise.
5171 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5172 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5173 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5175 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5177 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5180 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5183 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5185 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
5186 /bin/sh set unsorted output.

5195 (Writing Test Programs): Fix some langauge. Recommend exiting
5196 with status 1, not merely nonzero. Clarify exit declaration.
5197 (Run Time): Move C exit status stuff to new Exiting Portably section.

5205 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5207 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5208 since as_me isn't set yet.
5210 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5212 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5213 a few minor bugs in this area.
5215 * doc/autoconf.texi (Programming in M4sh): Comment out the
5216 documentation of AS_BASENAME, for now.
5217 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5218 (Limitations of Builtins) <basename>: Do not refer to
5220 * bin/autoconf.as (me): Don't use AS_BASENAME.
5221 (dir): Remove the unused variable.
5222 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5223 AS_DETECT_REQUIRED. All uses changed.

5236 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5238 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5239 of "run time" and "run-time" changed to "runtime", for consistency.

5243 * lib/autoconf/headers.m4: Likewise.
5245 * doc/autoconf.texi (Run Time): Document the exit status situation
5246 with more accuracy and detail.
5248 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5250 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5251 Archive is not officially `GNU' any more. Update URL.
5252 (Defining Directories): Likewise
5253 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5255 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5257 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5258 newline from the `trap' code to finish `config.log'; the NetBSD
5259 /bin/sh resets the exit status after an empty command, as
5260 documented in doc/autoconf.texi.
5261 Reported by Dalibor Topic <robilad@kaffe.org>.
5263 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5265 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5266 Suggested by Bruno Haible.
5268 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5270 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5271 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5272 Instead, just list the shells that we know work.
5273 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5274 changed. Be more cautious about the _cv_ variable.
5275 * tests/tools.at (Syntax of the shell scripts): Check the
5276 _cv_ variable once, at first, to avoid an internal autoconf error
5277 when sh -n does not work.
5279 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5281 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5283 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5285 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5286 use ">&-" since we're only 99.999% sure that this is portable,
5287 and since the MinGW bug is fixed in a different way.
5288 * lib/autotest/general.m4 (AT_INIT): Likewise.
5290 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5292 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5293 before opening config.log, to avoid hitting a bug on MinGW.
5295 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5297 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5298 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5299 This works around a MinGW bug reported by Eric Paire.
5300 Make sure that all writes to the log file append to it,
5301 rather than possibly losing data.
5302 * lib/autotest/general.m4 (AT_INIT): Likewise.
5304 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5306 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5309 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5313 * configure.ac (AC_INIT): Bump to 2.59d.
5315 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5319 * Makefile.maint (news-date-check): Do not require a leading `*'
5320 before the release date in NEWS.
5322 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5323 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5325 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5326 the instantiated file do not contain the string 'datarootdir'
5327 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5328 @mandir@, replace the reference '${datarootdir}' by the value.
5329 * tests/torture.at (datarootdir workaround): New test.
5330 * NEWS: Advertise this temporary fixup.
5331 Based on a patch by Bruno Haible, reported and analyzed by
5332 Paul Eggert and Noah Misch.
5334 2006-04-12 Eric Blake <ebb9@byu.net>
5336 * tests/autotest.at (Debugging a failed test): Fix comment.
5338 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5340 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5341 all the changes since 2006-04-07.
5343 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5345 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5346 succeeded, but `ln -s file dir' failed, take care to remove the
5347 leftover target before the next test, to prevent its spurious
5348 failure; also make sure `ln file dir' works before selecting it.
5349 Thanks to Keith Marshall for pointing this out.
5352 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5353 assignments in `at_debug_args', so that we put them correctly
5354 in the `run' script.
5355 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5356 Reported by Eric Blake.
5358 2006-04-11 Eric Blake <ebb9@byu.net>
5360 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5361 top-level tests after micro-suite has been run. Used in...
5362 (Debugging a successful test, Debugging script and environment),
5363 (Debugging a failed test): ...these new tests. The first of these
5365 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5366 macro, split out from...
5367 (AT_INIT): ...here, so that using -d also generates a run script.
5368 Document that -d inhibits top-level logging.
5369 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5370 inhibits top-level logging; debug scripts are created.
5372 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5374 * tests/autotest.at (Empty test, Empty check): New test to check it.
5376 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5379 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5381 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5382 the files if a problem appears. Make the empty *.at files
5383 read-only, too. Proposed by Ralf Wildenhues.
5385 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5387 * config/Makefile.am: Add comment to force updated Makefile.in.
5389 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5390 space only patch to this file, this patch causes the Makefile.in
5391 files that include freeze.mk to be updated, and thus have a
5392 newer time stamp again, which in turn makes a pristine CVS
5393 checkout have correct time stamps.
5395 * Makefile.maint (cvs-sv): New macro, to be used..
5396 (config.guess-url_prefix, config.sub-url_prefix)
5397 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5398 point to CVS text checkout of Gnulib files.
5399 (copyright-check): Bump current year.
5400 (announcement): Do not hard-wire `./announce-gen'.
5401 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5403 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5405 (wget_files): Update config.guess, config.sub, texinfo.tex by
5406 `wget-update', now that their URLs work again.
5408 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5410 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5411 Problem noted by Paul D. Smith.
5413 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5415 * doc/autoconf.texi: Remove unused words from word list.
5416 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5417 .x-sc_trailing_space: New files.
5419 * doc/standards.texi: Sync from gnulib.
5421 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5422 `LIBOBJDIR' as experimental.
5424 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5425 with a target directory; it's internally implemented as `cp'
5426 anyway, but since Autoconf advertises the possibility to use
5427 a target directory when LN_S is `ln -s', we need to find out.
5428 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5429 analyzed by Keith Marshall <keith.marshall@total.com>.
5433 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5435 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5436 confdefs.h as-is. In general, if it has backslash-newline or the
5437 like, then it doesn't work either to sort or to remove empty
5440 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5442 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5444 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5446 * lib/autom4te.in (Automake-preselections): Preselect
5449 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5451 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5452 apostrophe within a single-quoted string, as this is the usual
5453 tradition and is easier to read than '"'"'. Don't rely on the
5454 shell treating "$/" like '$/'. Use a more-consistent indenting
5457 2006-04-09 Eric Blake <ebb9@byu.net>
5459 * tests/autotest.at (Backquote command substitution),
5460 (Multiline backquote command substitution): Remove mistaken
5461 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5463 (Parenthetical command substitution, Multiline parenthetical
5464 command substitution): here.
5466 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

5499 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
5500 (C Compiler): Move AC_C_LONG_DOUBLE to ...
5501 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
5502 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.

5526 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
5528 2006-04-08 Stepan Kasal <kasal@ucw.cz>
5530 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
5531 of the warning introduced by the 2001-08-28 change.

5536 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
5537 variables shall be overriden by the cache.

5539 that contains braces.
5541 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5543 Revert the patch from 2006-04-01 and only improve
5544 _AS_DETECT_BETTER_SHELL:
5546 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
5547 skip nonexistent directories.
5548 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
5549 only shell candidates which exist.
5550 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
5551 * lib/autotest/general.m4 (AT_INIT): No need to give three
5552 parameters to _AS_PATH_WALK.
5554 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
5555 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5557 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
5558 distinguish m4sugar macros.
5559 * tests/tools.at (autoupdating with aclocal and m4_include):
5560 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
5561 test case by Noah Misch <noah@cs.caltech.edu>.
5563 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5565 Revert my change from 2006-03-17, in other words:
5566 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
5568 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
5569 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
5572 2006-04-07 Eric Blake <ebb9@byu.net>
5574 * doc/autoconf.texi (Programming in M4sh): Document that
5575 AS_MKDIR_P exits the script on failure.
5576 * lib/autotest/general.m4: Remove redundant AS_ERROR.
5578 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5580 * config/elisp-comp, config/install-sh, config/mdate-sh,
5581 config/missing, config/mkinstalldirs: Sync from Automake.

5595 Eric Blake <ebb9@byu.net>,
5596 Paul Eggert <eggert@cs.ucla.edu>,
5597 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5599 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
5600 whether `set' quotes correctly: redirect stderr of the tested
5601 `set', and use a subshell, for Ultrix; use `sed' instead of
5602 `grep' for zsh `set' which may write binary output; match only
5603 at the beginning of a line, to avoid false positives.
5604 In order to avoid false positives by unrelated variables with
5605 multiline content, put the dump algorithm in a subshell and
5606 unset all variables containing newlines (except some which are
5607 special to the shell). Warn about cache variables that are
5610 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5612 * config/config.guess, config/config.sub, config/texinfo.tex:
5615 * tests/mktests.sh: Reword comments.
5617 * tests/mktests.sh: Only skip internal macros starting with

5621 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
5622 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
5623 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
5624 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
5626 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
5627 shell issue with double-quoted command substitutions of native
5629 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith

5639 (sc_system_h_headers): Do not print rule on execution.
5640 (sc_tight_scope): Do not fail for non-existing `src' directory.
5641 (sc_changelog): Skip the Copyright footer.
5642 * lib/autoconf/lang.m4: Remove trailing space.
5644 * lib/autoconf/status.m4: More replacements to
5645 <tab><space> where this makes sense.

5650 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
5652 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
5653 ac_config_<foo>s again, sometimes normalized, sometimes not.
5654 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
5655 (AC_CONFIG_COMMANDS): Do not do so here.
5656 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
5657 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
5658 2005-07-25 rewrite. Noticed by Noah Misch.
5660 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
5661 _AC_PRESERVE_HELP_ORDER, ...
5662 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
5664 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
5665 inside m4_expand_once; it is redundant.
5667 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
5668 for --help from Cygnus `configure.'
5670 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
5672 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
5673 on a patch proposed by Ralf Wildenhues.

5680 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
5681 Noah Misch <noah@cs.caltech.edu>
5683 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
5684 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
5685 * doc/autoconf.texi (Help Formatting): New node.
5686 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
5688 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5690 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
5691 lib/autoconf/specific.m4, lib/autoconf/status.m4,
5692 lib/autoconf/types.m4, lib/autotest/general.m4,
5693 tests/mktests.sh, tests/torture.at: White space cleanup:
5694 remove some SPACE before TAB, or add quoting ('' or @&t@).
5696 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
5698 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
5700 2006-04-05 Eric Blake <ebb9@byu.net>
5702 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
5703 empty test suite works.
5704 * tests/autotest.at (Empty test suite): Remove xfail.
5706 2006-04-05 Noah Misch <noah@cs.caltech.edu>

5709 TAGS to ac_config_<foo>s.
5710 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
5711 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
5712 normalizing it, consistent it with previous releases.
5713 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
5715 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
5717 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
5718 Use simplified args that Eric Blake originally suggested.
5720 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
5722 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
5723 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
5724 Use 'comm' rather than N instances of grep; this also fixes a bug
5725 whereby substrings were incorrectly matched, causing us to not
5726 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
5727 (exclude_list): Exclude empty macros.
5728 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
5730 Use awk rather than grep -E or egrep, to avoid
5731 portability problems with regular expressions containing newlines.

5739 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
5740 a subdirectory subject to Cygnus `configure'.
5741 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
5743 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
5744 report request when we have no AC_PACKAGE_BUGREPORT.
5746 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5750 * tests/mktests.sh: Update copyright year in the header of the
5753 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
5754 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
5755 typedef'ed restricted pointer, to catch a compiler bug on
5756 HP-UX 11.x, and fix warnings so it passes with -Werror.

6600 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
6601 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned

6603 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
6604 comparing its address. Intel's interprocedural optimization was

6623 Stepan Kasal <kasal@ucw.cz>
6625 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
6626 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
6627 make its content writable before removing it. Remove an errorneous

6654 suggested by Ben Elliston. Handle weird characters correctly.
6656 2005-09-06 Stepan Kasal <kasal@ucw.cz>
6658 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
6659 calls, so that the final expansion of this macro is shorter.
6660 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
6661 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
6662 the cleanup there. Use AS_VAR_* macros, to be more general.
6663 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
6665 * lib/autoconf/general.m4: Use AS_IF where appropriate.
6667 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

6690 "if $undefined_var;" succeeds with my shell.
6692 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
6693 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

6704 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting

6713 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
6714 Update limitations about when to call AC_CONFIG_HEADERS.
6715 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
6716 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
6717 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
6718 ``Configuration Actions''; fix their index entries.
6720 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
6721 options correctly. Process N-M as M-N if M is smaller than N.
6722 Process ranges correctly so that N-N will run only N.
6723 Sort and uniquify the tests that will be run. If there is more
6724 than one test, reinsert the banners for the tests.
6725 * tests/autotest.at (Keywords): Unmark XFAIL.
6727 2005-08-23 Stepan Kasal <kasal@ucw.cz>
6729 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
6730 before passing the macro name to AH_TEMPLATE.
6732 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
6733 now opens log after option processing; in particular, --version
6734 and --help do not touch config.log.

6751 Prepend to LIBS, not append, in examples.
6753 2005-08-16 Stepan Kasal <kasal@ucw.cz>
6755 When building in place, set srcdir="."; suggested by Tim Van Holder.
6757 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
6758 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
6759 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
6760 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

6763 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6765 * tests/autoscan.at (autoscan): New file.
6766 * tests/suite.at: Use it.

6774 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
6775 add "2>&1"; gzip 1.2.4 prints help on stderr.
6777 2005-07-27 Stepan Kasal <kasal@ucw.cz>
6779 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
6780 was pushdef'ed twice while popped only once. Push it only once.

6795 2005-07-25 Stepan Kasal <kasal@ucw.cz>
6797 Rewrite substantial part of lib/autoconf/status.m4.
6798 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
6799 and CONFIG_COMMANDS are not processed in four separate loops.
6800 Instead, there is one main loop. This alows that the common code
6801 is expanded only once, thus config.status (and configure) is smaller.
6803 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
6804 the AC_LIST_FILES and cousins macros are no longer used.
6806 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
6807 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
6808 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
6809 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
6810 contain the initialization, nor the for loop, nor the associated
6811 commands; all these go to ...
6812 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
6813 _AC_OUTPUT_CONFIG_STATUS.
6814 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
6815 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
6816 (_AC_OUTPUT_FILE): The creation of the sed script ...
6817 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
6818 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
6819 _AC_OUTPUT_MAIN_LOOP.
6820 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
6821 _AC_CONFIG_COMMANDS): Use ...
6822 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
6823 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
6824 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
6825 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
6826 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
6827 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
6829 (_AC_CONFIG_UNIQUE): Update.
6830 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
6831 Replaced by this ...
6832 (_AC_LIST_TAGS): ... new common macro.
6833 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
6834 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
6835 (_AC_LIST_TAG_COMMANDS): ... new common macro.
6836 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
6837 this didn't belong to the `config commands' section.
6838 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
6839 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
6840 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
6841 to the `config commands' section either.
6842 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
6843 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
6845 ... and many changes to the comments nearby.
6847 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
6848 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
6849 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6850 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
6851 (#define header templates): The comment at the top of the generated
6852 header now includes the name(s) of the source file(s).
6854 Several unrelated small changes:
6856 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
6857 parameter to AC_DIAGNOSE.
6858 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
6859 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
6860 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
6861 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
6863 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
6864 in AC_OUTPUT doesn't double-quote it either.
6865 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
6868 2005-07-10 Stepan Kasal <kasal@ucw.cz>
6870 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
6871 versions of Portland Group compiler produce single- and double-quoted
6872 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
6873 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
6875 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
6877 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
6878 This is a corrected version of yesterday's patch.
6880 2005-07-07 Stepan Kasal <kasal@ucw.cz>
6882 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
6883 path, too; insert a "===" to emphasize the line.
6885 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
6886 ac_cv_build_alias to ac_build_alias.
6887 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
6889 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
6890 change eliminates it. Problem reported by Alexandre Duret-Lutz.
6891 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
6892 (AC_ARG_VAR): ... here.
6893 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
6896 Keep a list of all precious variables and process them with one simple
6897 for loop, instead of expanding all commands, or, OTOH, complicated
6898 processing of output of "set".
6899 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
6900 variable names in new macro...
6901 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
6902 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
6903 a loop to assign all ac_env_* and ac_cv_env_* variables.
6904 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
6906 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
6907 its value to shell variable ac_precious_vars and call
6908 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
6909 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
6910 _AC_ARG_VAR_VALIDATE.
6912 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

6930 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
6931 They are generated by the Tru64 v5.1B shell.
6933 2005-07-05 Stepan Kasal <kasal@ucw.cz>
6935 Fix my changes from 2005-07-01; reported by Noah Misch.

6940 Fix cases when the varsions of Autoconf and Autotest don't match.
6941 Reported by Noah Misch.
6942 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
6943 at_top_builddir, for compatibility with older autotest.
6944 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
6945 is not set, use at_top_builddir, for compatibility with older
6946 versions of autoconf.
6948 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
6950 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
6951 Problem reported by Patrick Welche.
6953 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
6955 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
6956 sed substitution command, so that we allow | in program prefixes
6957 and program suffixes. (& is a problem anyway; we're not fixing
6959 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
6960 configure_input, top_builddir, srcdir, etc.
6961 * lib/autotest/general.m4 (AT_INIT): Likewise, for
6962 PATH_SEPARATOR in AUTOTEST_PATH.
6964 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

6970 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
6972 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
6973 directories with weird names. Apparently some people like living
6974 on the edge. However, improve the test that "pwd" actually does
6975 report a name for the working directory.

6978 2005-07-01 Stepan Kasal <kasal@ucw.cz>

6995 document to output the default config_* lists to config.status.
6996 Don't recognize option --file, if the functionality is not there.
6997 Likewise for --header; moreover, recognize --he and --h as shortcuts
6998 for --help in that case.
7000 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7001 matches the order of execution. No code changed.

7023 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7024 (AC_SUBST): Call it.
7025 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7026 the directory specific variables; but don't call it for configure_input.
7028 2005-06-28 Derek Price <derek@ximbiot.com>
7030 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7033 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7035 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
7036 directory have inherent problems with special characters like spaces,
7037 due to limitations in Make syntax. Problem reported by Alexandre
7039 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
7040 Also, fix Tru64 porting problem with shell patterns,

7052 from Justace Clutter.
7053 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7054 variable into diagnostic. Make the diagnostic an error, not a warning,
7055 because we really don't support spaces and suchlike in dir names.
7056 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7057 Don't worry about backslashes in srcdir; it can't happen now.

7101 * doc/autoconf.texi:
7102 Don't mention Solaris versions so much, if a
7103 problem is common to all extant versions of Solaris. Say "SunOS
7104 4" instead of "SunOS" for SunOS 4.
7105 (awk): Mention more of the limitations of traditional Awk.
7106 (cat): Don't talk about cat -v.
7108 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

7122 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
7124 * doc/autoconf.texi: "filesystem" -> "file system".
7125 "behaviour" -> "behavior".
7126 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
7127 * lib/autoconf/general.m4: Omit blank after ":" sed command,
7129 * lib/m4sugar/m4sh.m4: Likewise.
7130 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
7131 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
7133 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
7134 (.x.1): Ignore the time stamp in the .TH line when deciding whether
7135 to update the man page. That way, we don't have to check in new

7146 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
7148 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7149 -u, since it outputs chatter if the input files are the same.
7150 Problem reported by Ralf Menzel.
7152 2005-06-08 Derek Price <derek@ximbiot.com>
7154 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7155 renaming them since they are about to be redefined anyhow.
7157 2005-06-08 Derek Price <derek@ximbiot.com>
7159 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7160 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7161 Move m4_undefine to alphabetical order.

7165 * README: Recommend GNU M4 1.4.3 or later.
7166 * doc/autoconf.texi (Introduction): Likewise.
7167 Reword to avoid some formatting glitches.
7168 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7169 Clarify explanation of HP compiler bug.
7170 Redo example output tp match current CVS snapshot.
7171 Use @example.org in email addresses when the examples
7172 might get inadvertently cut-and-pasted into user code.
7173 Remove example of autom4te usage that doesn't seem to work now.
7174 Use modern AC_INIT (except when the example is meant to be
7175 shown with Autoconf 2.13).
7176 Update ksh info for Solaris 9 and later.
7178 Modernize description of Automake versions a bit.
7179 Don't claim a future version of Autoconf is near.
7180 * doc/install.texi: Reword to avoid some formatting glitches.
7182 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7184 * doc/autoconf.texi: Add [] to examples, so that the manual
7185 follows its own advice about quoting better.
7186 Reword to avoid some formatting glitches.
7187 * doc/installt.exi: Reword to avoid some formatting glitches.
7189 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7190 Tru64 ksh pattern matching bug. Reported against Libtool by
7191 Albert Chin <libtool@mlists.thewrittenword.com> and
7192 Nicolas Joly <njoly@pasteur.fr>.
7194 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7196 m4_cdr of one-member list was [[]] (one-member list containing an
7197 empty string) instead of [] (an empty list. Callers were skewed to
7198 match this misbehaviour. As a consequence of this:
7199 - m4_foreach([x], [], [foo]) expanded to `foo', while
7200 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7201 This bug has been fixed:
7203 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7204 expand to an empty string; print error msg if called without
7206 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7207 misbehaviour; handle [] and [[]] correctly.
7209 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7211 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
7212 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
7213 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
7215 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7217 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7218 swallow records with more than 99 fields.
7219 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7220 parse the long line.
7222 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7224 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7225 swallow literals longer than 399. Reported by Ralf Wildenhues.
7226 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
7227 to workaround this limitation.
7229 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
7231 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7232 to gfortran, and make these the first two compiler names
7233 checked (following the general autoconf preference for gcc).
7235 2005-06-03 Stepan Kasal <kasal@ucw.cz>
7237 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7238 (DISTCLEANFILES): Remove $(check_SCRIPTS).
7239 (testsuite): Make sure autotest.m4f is up-to-date before using it.
7241 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
7243 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7244 expression of unbounded size when processing the --list
7245 option. This runs afoul of a limit of 399 bytes per regular
7246 expression on AIX. Problem reported by Ralf Wildenhues.
7248 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
7250 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
7251 * doc/autoconf.texi (Particular Headers): Reword example
7252 for multiline stdbool replacement.
7253 (Setting Output Variables): Reword text a bit. Don't
7254 give all the details about |#_!!_#|.
7255 Reword description of line replacement.
7257 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7259 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7260 now contain newlines, and substituted files must be referenced on
7261 a line alone; the sed scripts to substitute them are now very
7263 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
7264 commands can be put in a sed script portably.
7265 * doc/autoconf.texi (Setting Output Variables): Document above
7266 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
7267 use of multiline substitution.
7268 * tests/torture.at: No longer expect substitution of newline to fail.
7270 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
7272 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
7273 From Ralf Menzel (trivial change).
7275 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
7277 * tests/local.at: Don't attempt to check for negated character
7278 classes in shell scripts. The test was too brittle.
7280 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7282 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
7283 * doc/autoconf.texi (Limitations of Builtins): Document this
7286 2005-05-24 Stepan Kasal <kasal@ucw.cz>
7288 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
7289 common code; used in many places in the tree.
7290 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
7291 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
7293 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
7295 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
7296 messages when ac_unique_file is not found.
7297 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7298 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
7299 commands, for consistency with AC_MSG_ERROR and such.
7301 * bin/autoconf.as: Make more use of "shift 2" in option processing.
7303 * bin/Makefile.am: Merge the two rules for creating scripts.
7305 2005-05-23 Stepan Kasal <kasal@ucw.cz>
7307 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
7308 obsolete; it was never documented.
7309 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
7311 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7313 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
7314 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7315 (ac_top_builddir): ... this ...
7316 (ac_top_build_prefix): ... to this; the old name is also kept, for
7317 backward compatibility.
7318 (ac_top_builddir_sub): New variable, without the trailing slash,
7320 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
7321 * doc/autoconf.texi (Configuration Actions): Rename
7322 ac_top_builddir to ac_top_build_prefix.
7323 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
7324 at_top_builddir to at_top_build_prefix.

7327 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7329 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
7332 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7334 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7335 argument to m4_foreach. I guess it was necessary in the past,
7336 but I think it's a no-op now.
7338 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7340 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7341 ``cat <<_ACEOF'' commands to one.
7342 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
7343 * lib/autoconf/status.m4: On various places, use expr instead of
7345 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
7346 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
7347 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7349 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
7350 the wrong patterns between ``case'' and ``esac.'' The previous
7351 code had false positives.
7353 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
7355 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

7398 2005-05-13 Stepan Kasal <kasal@ucw.cz>
7400 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
7402 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
7403 enough arguments, similarly as in m4_bpatsubsts.
7405 2005-05-12 Stepan Kasal <kasal@ucw.cz>
7407 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
7410 2005-05-11 Stepan Kasal <kasal@ucw.cz>
7412 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
7413 for absolute directory names in one loop.
7414 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
7415 abbreviations of --version and --debug.
7417 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
7419 * doc/autoconf.texi (Autoconf Language): Be more precise about
7420 quoting rules. Problems noted by Stepan Kasal.
7421 Also, throughout this document, be more careful about white space.
7422 "blank", "white space", and "space" all have different meanings
7423 and we should be careful to say what we mean.
7425 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
7427 Fix C++ related problems reported by Werner Lemberg.
7428 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
7429 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
7430 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
7431 avoid problems with C++ and throw.
7432 * tests/compile.at: .cpp, not .cc.
7434 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
7436 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7438 * doc/autoconf.texi (Generic Functions): Typos.
7440 2005-05-02 Gary V. Vaughan <gary@gnu.org>
7442 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
7443 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
7444 set by latest automake.
7446 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7448 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
7449 outputs 0 on GNU/Linux these days.
7451 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
7453 * doc/autoconf.texi (Autoconf Language): Add more description
7454 about quoting heuristics.
7455 (Limitations of Builtins): Describe "set -" problems.
7457 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7459 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
7462 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
7463 by AC_DEFINE; it was a mistake.
7464 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
7466 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7468 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7470 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7472 * doc/autoconf.texi (External Software): Quadrigraphs are not
7473 processed correctly in AS_HELP_STRING; avoid this in the examples.
7474 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7475 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7476 comment and reduce m4_default([foo], []) to [foo].
7477 (m4_strip): Update the explanation.
7479 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7481 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7482 Remove core.conftest.* too; it's generated by Tru64 5.1.
7483 Problem reported by Jennis Pruett.
7484 * lib/autoconf/functions.m4
7485 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7486 Don't bother to remove core files; AC_RUN_IFELSE should do that
7489 2005-04-19 Stepan Kasal <kasal@ucw.cz>
7491 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
7493 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
7495 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.

7505 * doc/autoconf.texi (External Software, Package Options): Add
7506 examples showing how to implement --with-* and --enable-* options.
7508 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
7510 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
7511 as well as configure.in. Problem reported by Gregorio Guidi.
7513 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
7515 * doc/autoconf.texi (Particular Functions): Use gnulib's current

7529 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
7531 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7533 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
7534 Merge `-z option' as well for the benefit of Solaris link flags. Pass
7535 whole-archive (-zallextract, -zdefaultextract) options in the hope of
7536 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
7537 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
7539 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
7541 * NEWS: The configure command now warns you if you attempt to use
7542 a directory whose name contains a special character like space,
7544 * doc/autoconf.texi (Installation Directory Variables): Allow
7545 "," in file names. Do not use \@; it's not a portable regexp.
7546 * bin/Makefile.am (edit): Likewise.
7547 * lib/Makefile.am (edit): Likewise.
7548 * tests/Makefile.am (edit): Likewise.
7549 * tests/semantics.at: Likewise.

7551 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
7552 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
7553 * doc/autoconf.texi (File System Conventions): Warn about
7554 unportable file names.
7555 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
7557 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
7558 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
7559 ac_pwd, and quote srcdir.
7560 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
7562 * doc/autoconf.texi: Fix some systematic formatting problems.
7563 ".)" needs a following @: if not at the end of a sentence, and
7564 similarly for "!)". "etc." should be preceded by a comma.
7565 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
7567 2005-03-22 Bruno Haible <bruno@clisp.org>
7569 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
7570 argument is often called 'build-aux'.
7572 2005-03-07 Stepan Kasal <kasal@ucw.cz>
7574 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
7575 macro AC_TRY_LINK is obsolete.
7576 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
7579 2005-02-24 Stepan Kasal <kasal@ucw.cz>
7581 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
7582 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
7583 from a Common Lisp's `cl'.
7584 (AC_PROG_CXX): Behave according to the documentation: don't
7585 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
7586 make the variable CCC precious; use `cl.exe', not `cl'.
7588 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7589 Alexandre Duret-Lutz <adl@gnu.org>
7591 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
7592 /dev/null, as "configure" shouldn't read stdin, and this insulates
7593 us from problems (e.g., when testing for "cl"). Also, do this
7594 redirection before invoking "hostname" or "uname", and keep the
7595 original input stream available via...
7596 (AS_ORIGINAL_STDIN_FD): ... this new macro.
7597 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
7598 bother with "</dev/null" since it's now done at the top of
7600 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
7601 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7602 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7603 * doc/autoconf.texi (File Descriptor Macros): New section.
7604 (Printing Messages): Mention it.
7605 * tests/base.at (Input/Output): New test.
7607 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7609 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
7610 newline if neither \c nor -n work, as that would output two
7611 newlines. Prefer -n to \c. Reported by Stepan Kasal.
7613 2005-02-12 Stepan Kasal <kasal@ucw.cz>
7615 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
7616 This causes that any required macros inside will get before the if.

7619 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
7621 Undo previous change, except keep the change to
7622 lib/autoconf/programs.m4 that replaced grep with shell
7623 pattern-matching. This is because net-snmp configure reads stdin.
7624 Reported by Noah Misch.
7626 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
7628 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
7629 from /dev/null, as "configure" shouldn't read stdin, and this
7630 insulates us from problems (e.g., when testing for "cl").
7631 Suggested by Alexandre Duret-Lutz. Also, do this redirection
7632 before invoking "hostname" or "uname".
7633 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7634 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
7635 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
7636 "</dev/null" since it's now done at the top of 'configure'.
7637 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7638 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7639 Also, replace grep with shell pattern-matching, to save a process.
7641 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
7643 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7644 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
7645 avoid thinking that Allegro Common Lisp's "cl" command is a C++
7648 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
7650 * doc/autoconf.texi (Limitations of Usual Tools): Document that

7663 Sort environment variable names.
7664 Mention that shells no longer inherit IFS.
7665 Don't recommend PATH_SEPARATOR=';' so strongly.
7666 Mention that $RANDOM might expand to the empty string.
7667 "symlink" and "soft link" -> "symbolic link".
7668 Improve mktemp description (reported by Bruno Haible).

7744 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
7746 Try not to generated lines of unlimited length, as POSIX places a
7747 2047-byte limit on line length of portable text files.
7748 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
7749 Use newline as a separator, not space.

7784 Modified from a suggestion by Stepan Kasal.
7786 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

7807 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
7808 Update the long comment explaining it.
7810 m4_require no longer writes an ``is required by'' line to the
7811 execution stack. It contains only one bit of non-redundant
7812 information: that the macro was required, not called. And even
7813 this bit is useless in most situations: have you ever met a macro
7814 which both calls and requires the same macro?
7816 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
7817 (_m4_defun_pro_outer): ... only via this macro, for the outermost

7822 execution stack; slightly improve the out-of-a-defun error message.
7823 (_m4_divert_grow): New macro, counter for the temporary diversions.
7824 (_m4_require_call): Use it.
7825 * tests/m4sugar.at (m4_require): Expect output without the
7826 ``is required by'' messages.
7828 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

7864 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
7865 Warn about newline stripping in `` and $(). Update Solaris
7867 (Limitations of Builtins): Use expr "X...", not expr "x...", as
7868 X insulates us from future changes to Posix.
7869 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
7872 2005-01-19 Stepan Kasal <kasal@ucw.cz>
7874 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

7894 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
7896 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

7918 (_m4_divert_n_stack): New macro; the expansion is
7919 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
7921 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
7922 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
7923 stored in _m4_divert_diversion or _m4_divert_dump.
7924 (m4_divert_pop): When the parameter is given, compare the symbolic
7925 name with the last diversion pushed on the stack. Previously, the
7926 current diversion was compared with the numeric value of the
7927 diversion given as the parameter.
7928 (m4_require): If the macro hasn't been expanded yet, call ...
7929 (_m4_require_call): this new macro.
7931 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7962 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

8143 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

8211 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
8212 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.

8234 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
8236 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8237 "char c = '\200';" rather than "char c = 0x80;" as the

8239 overflow on signed char hosts.
8241 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
8242 to -qlanglvl=ansi. We don't want to disable extensions.

8355 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
8356 "/usr/include", clear ac_x_includes instead of leaving it as "no"
8357 (trivial change). Problem and patch reported by Andrew Church in:

8424 This isn't a complete fix but it's an improvement.
8426 * bin/autoconf.as (autom4te_options): New var.
8427 Use it instead of appending to AUTOM4TE, so that we can allow
8428 spaces in the build directory's absolute name.
8429 * bin/autoheader.in ($autoconf): Allow spaces in file names.

8461 * lib/autom4te.in (Automake-preselections): Preselect
8462 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8464 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8466 * lib/autom4te.in (Automake-preselections): Preselect
8467 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will

8483 useful for pkdsh, too.
8485 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
8487 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8488 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8489 Don't fail if ENV or BASH_ENV is readonly.

8502 names like "aux". Problem reported by Eric Blake.
8504 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
8505 by zero instead of array size, so that we can use any arithmetic
8506 constant expression (instead of requiring an integer constant
8507 expression). This allows us to test expressions like DBL_MAX <
8508 LDBL_MAX, which didn't conform to the C standard using the old
8510 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
8511 now that we can do floating-point tests at compile time.
8513 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8515 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8516 and LDBL_EPSILON, as the resulting expression isn't an
8517 integer constant expression and violates the C standard.
8518 Problem reported by Nelson H. F. Beebe. Also, check
8519 for "L" suffix, and check that long double doesn't have
8520 worse range or precision than double, that mixed-mode
8521 arithmetic doesn't generate a diagnostic, that double
8522 constants fit in long double.

8546 Problem reported by Stepan Kasal.
8548 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8550 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
8551 change). Patch reported by Ralf Wildenhues in
8552 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
8554 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8555 function F exists if the compiler and linker let you compile an
8556 expression like (F != 0). Recent versions of GCC optimize away
8557 the reference to F in that case, since every function address must
8558 be nonzero, so the link succeeds even if F does not exist.
8559 Problem reported by Manu in
8560 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
8562 * doc/autoconf.texi (Systemology): Standardize on the spelling of
8563 "Unix". Many uses changed.
8564 (Limitations of Builtins): Explain better why the ! command isn't
8567 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
8569 * lib/autom4te.in (Automake-preselections): Preselect
8570 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
8572 2004-05-19 Kevin Ryde <user42@zip.com.au>
8574 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
8575 referencing AC_FUNC_STRERROR_R.
8577 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
8578 note pessimistic assumption when cross compiling.
8580 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
8582 * doc/autoconf.texi (Limitations of Make): Note that BSD make
8583 (until 2004) invoked subcommands with sh -e, contra POSIX.
8584 Reported by Kevin Ryde.
8586 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
8588 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
8589 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
8590 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
8591 `test -f " /usr/bin/grep"', which _always_ failed.
8592 (AC_PROG_SED): Ditto bogus PATH fix.
8593 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
8594 requires that grep correctly supports _multiple_ `-e' options, rather
8595 than stating only that grep should accept `-e'.
8597 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
8599 Port to C99, which requires that 'exit' be declared.
8601 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
8602 to ensure that stdlib.h is included.
8603 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
8604 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
8605 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
8606 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
8607 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
8608 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
8609 when using 'exit' in a test; C99 requires that 'exit' be declared.
8611 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
8613 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
8614 now prefers 'grep' implementations that accept -e.
8615 (Limitations of Usual Tools): Describe problems of traditional
8616 egrep and fgrep with long input lines, and of traditional grep
8618 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
8619 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
8620 All callers changed. Append /usr/xpg4/bin to the PATH, for
8622 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
8623 the user with complaints about multiple -e options.
8624 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
8625 Define it with AC_PROG_GREP.
8626 * configure.ac (AC_PROG_GREP): Add.
8627 * lib/freeze.mk (GREP): New macro.
8629 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
8631 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
8632 a possible candidate only after all others fail, rather than
8633 consulting it first. This improves backward compatibility by
8634 better reflecting the way shell selection occurred in previous
8635 versions of Autoconf, and should help to avoid triggering latent
8636 problems in other packages, such as the one in Automake where zsh
8637 is not handled robustly:
8638 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
8639 Although it is not Autoconf's responsibility to work around
8640 problems in Automake, it nevertheless makes sense to avoid
8641 introducing unnecessary incompatibilites.
8643 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
8644 Gary V. Vaughan <gary@gnu.org>
8646 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
8647 how deeply nested we are when a suitable tool is found, set the
8648 ac_path_TOOL_found flag.
8649 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
8650 nested we are in this macro. Break out of all 3 nested loops if
8651 ac_path_TOOL_found is set.
8653 2004-04-21 Gary V. Vaughan <gary@gnu.org>
8655 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
8656 of the _AS_PATH_WALK loop too if GNU flavor is found.
8658 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
8660 * doc/autoconf.texi (Limitations of Make): Update documentation
8661 for `$<'. New entry `Long lines', based on a report from Simon
8662 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
8663 paragraph about DJGPP, based on a mail from Richard Dawe.
8665 2004-04-20 Paul Eggert <eggert@twinsun.com>
8667 * tests/c.at (C keywords): Don't assume that GCC supports
8668 "restrict" and "inline", as sufficiently-old GCC versions do not
8669 (also, GCC configured to be in pedantic C89 mode does not).
8670 Problem reported by Sumit Pandya in:
8671 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
8673 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
8674 consider -g to work if it generates warnings when plain compiles
8675 don't. Problem reported by Braden McDaniel in:
8676 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
8678 * doc/autoconf.texi (Slashes): New section, to document a problem
8679 reported by Jim Meyering in:
8680 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
8682 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
8683 linker output files before linking, to work around IRIX 6 linker bug.
8684 Problem reported by Rainer Orth in:
8685 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
8687 2004-04-20 Gary V. Vaughan <gary@gnu.org>
8689 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
8690 best tool so far counter rely on the tool path variable name to
8691 avoid checks for one tool being affected by the results of running
8692 the length check on a previous tool.
8694 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
8695 match expression argument, as different greps have different
8696 regular expression flavours.
8697 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
8699 (AC_PROG_EGREP): Pass 'EGREP$'.
8700 (AC_PROG_GREP): Pass 'GREP$'.
8702 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
8704 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
8705 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
8707 2004-03-29 Paul Eggert <eggert@twinsun.com>
8709 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
8710 Types, Specific Compiler Characteristics, System Services,
8711 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
8712 etc. consistently instead of 'long', 'short', 'unsigned' etc.
8713 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
8714 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
8716 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

8725 2004-03-28 Paul Eggert <eggert@twinsun.com>
8727 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
8728 now defines HAVE_DECL_TZNAME if it is declared, when
8729 HAVE_STRUCT_TM_TM_ZONE is not defined.
8730 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
8731 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
8734 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
8736 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
8737 superfluous backslashing of quotes (") in sed expressions;
8738 thanks to Paul Eggert.
8740 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
8742 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
8743 Fortran compiler is ifort, also added pghpf; thanks to Nelson
8744 H. F. Beebe for the bug report.
8746 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
8748 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
8749 quoted -cmdline argument in Portland Group compiler (bug
8750 reported by Jeffrey J. Barteet).
8752 2004-03-25 Kevin Ryde <user42@zip.com.au>
8754 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to

8779 * tests/mktests.sh: Do not generate tests for the
8781 * NEWS: Document these changes.
8783 * doc/autoconf.texi: Avoid macros with unbraced arguments,

8794 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
8795 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
8798 2004-03-03 Paul Eggert <eggert@twinsun.com>
8800 * bin/Makefile.am (edit): Don't use $< in a context where
8801 POSIX doesn't require support for it. Use $@.in instead.
8802 Problem reported by Anthony N. Frasso in
8803 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
8804 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

8808 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
8809 from the next generation of Libtool.
8810 * lib/autom4te.in (Autoreconf-preselections): Ditto.
8812 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8814 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
8815 is not always thread-safe. Report from Nathanael Nerode.
8817 2004-02-18 Paul Eggert <eggert@twinsun.com>
8819 Fix a dependencies problem, stemming from a Autoconf 2.59 build
8820 problem on QNX reported by Stephen Rasku in
8821 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
8823 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
8824 $(m4sh_m4f_dependencies); this removes a FIXME.
8825 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
8826 (MAINTAINERCLEANFILES): Split into pieces,
8827 one per related section. Add $(srcdir)/wrapper.in.
8829 2004-02-09 Paul Eggert <eggert@twinsun.com>
8831 * doc/autoconf.texi (Setting Output Variables): Emphasize that
8832 AC_SUBST provides no portable way to escape literal newlines.
8834 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
8835 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
8836 Darwin uses -lcrt2.o and there's little point to cataloging all
8837 the system variants. Partial fix reported by Andreas Waechter in:
8838 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

8852 refer to the correct file.
8853 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
8854 the behavior of the third argument.
8855 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
8856 correctly the behavior of the third argument. Document
8857 what the three macros that AU_DEFUN defines do. Fix
8858 warning message when the third argument includes $0
8859 (reported by Alexandre Duret-Lutz).

8862 Eric Sunshine <sunshine@sunshineco.com>
8863 Paul Eggert <eggert@twinsun.com>
8865 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

8882 use AS_INIT_WITH_SHELL_FN.
8883 * bin/autoconf.in, tests/wrapper.in: Regenerated.

8913 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
8914 2003 (except 1997) to the list of copyright years. This undoes
8915 the 2003-05-22 change, which removed the older years from the list.
8916 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

8922 grep or ggrep program in PATH that accepts as long lines as
8924 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
8926 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
8927 egrep and fgrep respectively if $GREP -E/-F don't work.
8928 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
8929 _AC_PROG_GREP, and AC_PROG_SED.

8960 2004-01-26 Paul Eggert <eggert@twinsun.com>
8962 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
8963 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
8964 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
8965 not <inttypes.h>. Problem reported by Tim Mooney in
8966 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
8967 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
8970 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
8971 otherwise "make check" fails because it forbids cmp (I guess
8972 because cmp treats files as binary on DOS-like systems).
8974 * tests/mktests.sh: Update copyright date to 2004, since some tests
8975 have changed in 2004.
8977 2004-01-23 Gary V. Vaughan <gary@gnu.org>
8979 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
8980 non-truncating sed or gsed program in PATH.

8982 * doc/autoconf.texi (Particular Programs): Document it.
8985 2004-01-15 Paul Eggert <eggert@twinsun.com>
8987 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since

8994 * doc/autoconf.texi (Programming in M4sh): Document that
8995 AS_MKDIR_P succeeds if the destination is a symbolic link
8996 to an existing directory.
8997 (Limitations of Usual Tools): Note that mkdir -p might not
8998 succeed on symlinks to directories.

9018 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9019 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9020 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9021 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9022 AC_COMPILE_IFELSE, since we now assume our caller invokes
9023 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9024 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9025 of AC_RUN_IFELSE; this avoids the warning mentioned above.

9031 `"'...'"`, as it's confusing (and I suspect it may not work on

9107 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

9500 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
9501 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
9502 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

9507 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
9508 directory for AC_CONFIG_COMMANDS' first argument exists.
9509 This makes valid the invocation of _AC_SRCPATH that follows.
9510 Reported by Eric Sunshine.
9511 * doc/autoconf.texi (Configuration Commands): Adjust.
9513 2003-09-26 Akim Demaille <akim@epita.fr>
9515 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
9516 Reported by Ralf Corsepius.
9518 2003-09-26 Akim Demaille <akim@epita.fr>
9520 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
9522 Actually, use AU_ALIAS.
9525 2003-09-26 Paul Eggert <eggert@twinsun.com>
9527 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
9528 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.

9534 The test suite are sometimes assigning timings incorrectly.
9535 Reported by Henk Krus.
9536 Diagnosed by Nicolas Joly.
9538 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
9540 Instead of making AT_help a sequence of assignments to grow
9541 $at_help_all, just make AT_help_all be the growing contents of
9542 $at_help_all, and make a single assignment in...
9544 (at_times_skip): Flip the meaning and rename as...

9554 * bin/Makefile.am (edit): Handle '@configure_input@'.
9555 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
9556 (ifnames): chmod -w.
9557 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
9558 executables, not bin/ executables! Otherwise all the magic needed
9559 to find non installed files is turned off. This caused a failure
9560 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
9561 as found in its environment (sent by tests/autoreconf): pointing
9562 to bin/autom4te that could not find its files.
9563 * tests/mktests.sh: Force the replacement of generated files, for
9564 the sake of "mv" program that are interactive when overwriting a

9659 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
9661 Add support for newer Fortran dialects. The F77 interface is
9662 unchanged, and continues to support Fortran 77. New FC macros
9663 correspond to all the old F77 macros, with output variables FC,
9664 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
9665 available dialect, but older dialects can be specified. There are
9666 new macros AC_FC_SRCEXT to set the source extension, and
9667 AC_FC_FREEFORM to accept free-form source files.

9793 2003-08-21 Akim Demaille <akim@epita.fr>
9795 First stab at preserving warnings between calls to autom4te,
9796 including when the cache is used.
9798 There are still several issues: (i) there are too many runs of m4
9799 (one for include, one for warnings, and some more), (ii) warnings
9800 spreading on several lines are not handled gracefully, (iii) the
9801 code meant to have the call stack display for errors does not work
9802 (its handling should move from m4 to autom4te).
9804 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
9806 (@preselect): Add m4_warn.
9807 ($exit_status): Remove, use $exit_code.
9808 ($help): Use Autom4te::ChannelDefs::usage.
9809 (&handle_m4): No longer define the m4_warnings.
9810 At each run, extract and report the warnings.
9811 Always cache the result, including if the exit status is on
9812 failure, since if nothing changes, we should result in the same
9813 failure, hence we can use the cache.
9814 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
9815 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
9817 (m4_warn): Redefine as a do-nothing: it is its invocation that
9818 matters, as warnings are now reported via traces.
9819 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
9820 the contents of m4_warn: make it _call_ m4_warn, so that tracing
9821 the latter reveals calls to the former.
9825 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
9827 2003-08-21 Akim Demaille <akim@epita.fr>
9829 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

9854 Reported by Alexandre Duret-Lutz.

9858 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
9859 * bin/autom4te: Adjust.
9860 In particular, be Autoconf tools are really silent when properly
9861 working, bind the verbosity of the 'note' channel to $verbose.
9862 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
9863 (&xsystem, &contents): Remove, since they are exported by...

9925 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
9926 shorter column three. Add DESCRIPTION to log file content.

9986 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
9987 not all of them. This fixes 1. the fact that when testing
9988 Autoconf there are many many config.log, 2. the incorrect use of
9989 top_srcdir to find config.log.
9990 Don't mix the detailed output of failed test with the summary of
9991 failures. Rather, append detailed log afterwards.

10084 63 for version mismatches.
10086 2003-05-23 Akim Demaille <akim@epita.fr>
10088 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10089 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10090 the middle of a line).
10091 * lib/m4sugar/m4sugar.m4: Likewise.
10092 Remove useless spaces in comments.
10094 2003-05-23 Akim Demaille <akim@epita.fr>
10096 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an

10110 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10111 Remove `#include <stdlib.h>' from the list; we should never
10112 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10113 resulting namespace pollution would cause other tests to fail.
10114 Configure scripts run with some older versions of g++ and HP's
10115 aCC would fail due to such an #include. Problems reported by
10116 Matthew Mueller in <http://bugs.debian.org/120704> and by
10118 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10119 In the test, use the test declaration before including <stdlib.h>,
10120 as that's closer to how it'll be used.
10122 2003-05-23 Akim Demaille <akim@epita.fr>
10124 * doc/autoconf.texi (Header Portability): ucred.h.
10127 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10129 Overhaul Autotest's logging: generate separate log files
10130 in testsuite.dir/NNN/testsuite.log, and append them to
10131 testsuite.log instead of re-running the test verbosely.
10133 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10134 file descriptor, write 0 to at_status_file instead of setting
10135 at_status=0, initialize some new variables (at_status_file,
10136 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10137 to rerun the tests, instead append the at_group_log to the
10138 at_suite_log when a test fails.
10139 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10140 with the AS_MESSAGE_LOG_FD redirected to stdout.
10141 (AT_CLEANUP): save the output status in $at_status_file
10142 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10143 its original place.
10144 (AT_CHECK): since tests are run with a redirected stdout,
10145 and used to be re-run in verbose mode, turn some $at_verbose
10146 into echo, and don't redirect the output of testing stdout
10149 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10150 the name of the debugging directory and information about

10270 2003-05-06 Akim Demaille <akim@epita.fr>
10272 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10273 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10274 by aclocal.m4 is changed it might require the importing of another
10275 m4 extension file, i.e., aclocal must be run.

10292 2003-04-29 Derek Price <derek@ximbiot.com>
10294 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the

10296 (AT_CLEANUP): Add `;' to end of at_help_all.
10297 (AT_INIT): Allow --keywords to be specified more than once. When

10305 align better with others. I also made some of the individual
10306 entries on one line, for brevity and to make it easier for me to

10494 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
10495 to fix a mismatch between example and discussion.

10499 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
10500 format starting with "-".
10502 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
10504 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
10505 is not portable inside Makefile.
10507 2003-02-20 Akim Demaille <akim@epita.fr>
10509 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When

10511 Conversely, prompt the reader to send a bug report to the
10512 maintainers of the package, not of Autoconf.
10514 2003-02-20 Klee Dienes <kdienes@apple.com>
10516 * bin/autoreconf.in (autoreconf_current_directory): Properly
10517 handle an empty aclocal.m4.

10522 $ac_prefix_program.
10525 2002-12-23 Paul Eggert <eggert@twinsun.com>
10527 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10528 innocuous variant befor including <limits.h> or <assert.h>. This
10529 works around a bug reported by Albert Chin: HP-UX 11i
10530 (and earlier versions) have a <limits.h> that declares
10531 gettimeofday and many other functions.
10533 2002-12-03 Paul Eggert <eggert@twinsun.com>
10537 * NEWS, configure.ac: Update version.
10539 * doc/fdl.texi: Upgrade to FDL version 1.2.
10541 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
10542 nontrivially in main's body, so that f's external declaration is
10543 not optimized away in AIX. This should fix the bug reported by
10545 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
10547 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10548 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10549 defined, to support freestanding compilers. This should fix the
10550 bug reported by Momchil Velkov in
10551 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10553 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10554 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

10585 Update from masters.
10587 2002-11-14 Akim Demaille <akim@epita.fr>
10589 * Makefile.maint: Sync with Bison, i.e.:
10590 (po-check): Scan .l and .y files instead of the
10591 .c and the .h files that they generate. This fixes the bug
10592 reported by Tim Van Holder in:
10593 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
10594 Look for N_ as well as for _. Try to avoid matching #define for
10598 2002-11-14 Akim Demaille <akim@epita.fr>
10600 * doc/autoconf.texi (C Compiler): Compiling several files at once.

10610 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
10611 than assigning in main, to avoid HP cc +O3 optimizing it away.

10615 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
10616 option. Process --recheck after parsing all options. Pass -q
10617 option to configure on --recheck.
10618 (AC_OUTPUT): Pass -q from configure to config.status.
10619 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
10620 arguments to record.
10621 * doc/autoconf.texi (config.status Invocation): Document
10622 config.status -q option.
10624 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
10626 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
10627 Makefile.in if Makefile.am exists.
10628 (output): Strip `.am' from Makefiles. Don't
10629 output AC_CONFIG_FILES if no Makefiles were found.

10649 Reported by Ezra Peisach.
10651 2002-11-05 Akim Demaille <akim@epita.fr>
10653 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
10655 We _have_ to stop using the old compatibility scheme that tried to
10656 avoid useless backslashes because Libtool 1.4.3 contains a
10657 AC_DEFINE([error_t], [int],
10658 [Define to a type to use for \`error_t' if it is not
10659 otherwise available.])
10660 We _have_ to quote the single quote and backslashes with \. The
10661 old compatibility scheme saw that ` was backslashed, and therefore
10662 did not quote the single quote. Hence before this patch, Autoconf
10663 was not compatible with Libtool.
10665 2002-11-04 Paul Eggert <eggert@twinsun.com>
10667 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

10708 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
10709 Make variable, not a shell variable.
10710 Suggested by Bruno Haible.
10712 2002-10-31 Akim Demaille <akim@epita.fr>
10714 * bin/autom4te.in (load_configuration): Reject #args out of any

10993 words about HP-UX cmp: it was actually a user-written cmp.
10995 2002-10-22 Akim Demaille <akim@epita.fr>
10997 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
10998 are a few warnings.
10999 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
11000 Quote for Perl '' strings, not "".

11004 2002-10-22 Akim Demaille <akim@epita.fr>
11006 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
11007 characters is a syntax warning now.
11008 (_AS_QUOTE): Accept $2 as list of characters to quote.
11009 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
11010 Quote for Perl, not sh.

11014 `@', to tickle Perl's lists.
11015 Reported by Carlos Velasco.
11017 2002-10-18 Akim Demaille <akim@epita.fr>

11021 Thanks to Alexandre Duret-Lutz.

11031 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.

11050 2002-10-16 Akim Demaille <akim@epita.fr>
11052 Because of caching, some files that no longer exist and are no
11053 longer required can still cause errors.
11054 Reported by Alexandre Duret-Lutz.
11056 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
11057 to frozen files in @ARGV, as @ARGV must remain being a list of
11058 files. Rather, at M4 call sites, use this...
11059 (&files_to_options): New function.
11060 (&freeze): Use &error.
11061 (&up_to_date): If a file that was included according to the cache
11062 is no longer there, then the output is out dated.

11065 * tests/tools.at (autom4te cache): New.
11067 2002-10-16 Akim Demaille <akim@epita.fr>

11070 * bin/autoupdate.in (&parse_args): Kill old options.
11071 * bin/autoreconf.in (&parse_args): Remove dead options.
11073 (&autoreconf): Report the directories we enter *and leave*, so
11074 that error messages can be easily located, and use GNU Make
11075 format, so that Emacs' compile mode understands us.
11076 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11077 if some file was changed instead of `print'.
11078 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

11086 2002-10-11 Akim Demaille <akim@epita.fr>

11112 file name to enable parallel executions.
11113 From Sam Varshavchik.
11115 2002-10-08 Akim Demaille <akim@epita.fr>
11117 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11118 aclocal invocation, as Gettext macros might not be visible to
11120 Instead of blindly running autopoint, scan configure.ac (not the
11121 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11122 Reported by Paul D. Smith.
11124 2002-10-08 Paul Eggert <eggert@twinsun.com>
11126 Work around problems found when POSIXLY_CORRECT=1 is set.
11127 None of this seems to have anything to do with POSIX, really,
11128 but it's how Perl getopt works.
11129 * bin/autom4te.in (parse_args): Configure GetOpt with
11131 * doc/autoconf.texi (Invoking autom4te):
11132 --warning -> --warnings.

11152 2002-09-28 Akim Demaille <akim@epita.fr>
11154 * tests/torture.at (Configuring subdirectories): Be robust to
11155 users who use config.site to require for a cache: in this case,
11156 the two last configure runs, using two different sets of
11157 arguments, trigger a legitimate error.
11159 2002-09-28 Akim Demaille <akim@epita.fr>

11178 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11179 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

11193 (.m4.m4f): Don't pass --prepend-include, since that's done by
11194 tests/autom4te itself.
11195 * lib/autoscan/Makefile.am: Include freeze.mk.
11196 (autoscan.list): New target --this file is no longer a source.

11204 tracking changes in autoscan.list.
11205 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11207 2002-09-28 Akim Demaille <akim@epita.fr>

11221 * bin/autoscan.in (&init_tables): Adjust.
11223 2002-09-28 Akim Demaille <akim@epita.fr>
11225 From now on, autoscan files must always map a macro name to a

11228 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11230 * lib/autoscan/functions, lib/autoscan/headers: Make the macro

11321 Suggested by Guido Draheim.
11323 2002-09-13 Akim Demaille <akim@epita.fr>
11325 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11326 (chdir_init) might hang when stat'ing mounted directories.

11391 precious variables are.
11392 Suggested by Pontus Skoeld.

11396 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11397 (ifnames, autoscan, autom4te): Since we don't only depend on
11398 configure.ac variables (such as VERSION etc.), but also on prefix

11400 Reported by Alexandre Duret-Lutz.
11401 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11403 2002-09-05 Kevin Ryde <user42@zip.com.au>

11453 * bin/autoupdate.in: Use error instead of die.
11455 2002-09-01 Paul Eggert <eggert@twinsun.com>
11457 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11458 ordinary shell concatenation rather than echo+tr+sed command that
11459 runs afoul of a long-line-related sed bug in Solaris 8.
11461 * bin/autoheader.in (parse_args): --warning -> --warnings.
11463 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to

11470 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,

11475 * doc/autoconf.texi (Special Shell Variables): Mention
11476 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.

11479 MAILPATH and set PS1, PS2, PS4 to default values, to work
11480 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11481 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11482 the Autoconf documentation specifies; fall back to "unset" only if
11483 this fails. Use a shell for-loop for this rather than an m4 loop,
11484 to shorten the output script.
11486 2002-08-30 Paul Eggert <eggert@twinsun.com>
11488 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11489 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11490 for the CDPATH problem. Document PWD.
11491 (Limitations of Builtins): Document the problem that "cd $foo" and
11492 "ls $foo" may refer to different directories in shells conforming
11493 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11494 example, since the old example is now out of date.
11496 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11497 FOO" and "ls FOO" talk about different directories; this catches
11498 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11501 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11502 of rolling our own unset.
11503 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
11504 in practice we needn't worry about CDPATH if unset doesn't work.
11506 * Makefile.in, aclocal.m4, bin/Makefile.in,
11507 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
11508 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,

11528 2002-08-29 Akim Demaille <akim@epita.fr>
11530 * lib/Autom4te/General.pm (&xqx): New.
11531 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11532 hand, which is not portable.
11534 * bin/autom4te.in: Use them.
11535 Use &error instead of die.
11536 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11539 2002-08-17 Paul Eggert <eggert@twinsun.com>
11541 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
11542 default list of compilers to try, since it was long ago superseded
11543 by the ksh fc builtin. Suggested by Steven G. Johnson.
11545 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
11547 * doc/autoconf.texi (Invoking autom4te): End the option table,
11548 fixing a bug introduced by the previous patch.
11549 (Limitations of Make): Add a 'target lookup' subentry in the
11550 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
11552 2002-07-29 Mark D. Roth <roth@feep.net>
11554 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
11555 options and use $AUTOM4TE_PATH.
11556 * doc/autoconf.texi: Remove documentation of autom4te
11557 --include-envvar and --site-macro-subdir options and document
11558 use of $AUTOM4TE_PATH.
11559 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
11560 arguments from each language section.

11564 * doc/install.texi: Include copyright symbol in copyright notice.
11566 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
11568 (AM_MAKEINFOFLAGS): New macro.
11569 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
11570 * Makefile.am (INSTALL): Use the new macros.
11571 Use -o rather than --output, since "missing" does not grok --output.
11573 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11575 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
11576 comments do not always work. Never trust the exit status of

11581 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):

11584 2002-07-23 Paul Eggert <eggert@twinsun.com>
11586 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
11587 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
11588 apparently treats PATH="nonexistent" as if it contained ".".
11589 Bug reported by Stefan `Sec' Zehl.

11750 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
11752 * bin/autom4te.in ($cache): Don't define using `$me', the name

11859 This improves on an earlier suggestion by H. Peter Anvin.
11861 2002-05-16 Paul Eggert <eggert@twinsun.com>
11863 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
11864 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
11865 Both macros now accept an optional source-dir arg.
11866 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
11868 * NEWS: Document this.
11869 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
11871 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
11872 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
11873 not for GNU extensions; this undoes part of the 2000-11-03 change,
11874 reverting to 2.13-compatible behavior.
11875 Add new optional argument DIR.
11876 (AC_FUNC_FNMATCH_GNU): New macro.
11878 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
11880 2002-05-08 Paul Eggert <eggert@twinsun.com>
11882 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
11883 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
11884 and it causes a 'test' syntax error if it fails.
11885 Bug reported by Stephen Gildea.
11887 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
11888 If prototypes are supported, use them to check this at compile-time,
11889 instead of trying to check it at run-time. If we must do a run-time
11890 check, assume that setvbuf is standard when cross-compiling, as
11891 nonstandard setvbuf occurs only on ancient and unlikely hosts.
11892 Bug reported by Paul D. Smith.
11894 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
11895 argument specifying location of getloadavg.c. This removes a
11896 FIXME. This idea was taken from Jim Meyering's implementation in
11898 * doc/autoconf.texi (Particular Functions): Document this.
11899 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
11900 that's what the code does; this fixes a bug reported by
11903 2002-05-03 Akim Demaille <akim@epita.fr>
11905 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
11906 autopoint instead of gettextize.
11907 ($uses_alocal): Rename as...
11908 ($uses_aclocal): this.
11909 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11910 Suggested by Bruno Haible.

11916 2002-04-29 Paul Eggert <eggert@twinsun.com>
11918 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
11919 files to be 1 second older; just set them to be the same time.
11920 Also, sleep 1 second after the first aclocal, to work around
11921 problems with sub-second time stamps on the input files.
11923 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
11925 * doc/autoconf.texi: Mention "set -e -x" lossage

11932 From Christian Cornelssen.
11934 2002-04-29 Akim Demaille <akim@epita.fr>
11936 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
11937 of lack of $LINENO support, then the test will compare the $LINENO
11938 in testsuite vs. the lineno in the test file. This is wrong, of
11940 Be sure to protect it.
11941 Reported by Patrick Welche.
11943 2002-04-25 Akim Demaille <akim@epita.fr>
11945 * doc/autoconf.texi (Obsolete Macros): Typo.
11946 Reported by Vladimir Volovich.
11948 2002-04-25 Akim Demaille <akim@epita.fr>
11950 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
11951 than some of the input files, hence, on the second run of aclocal,
11952 if some of its input are younger, make them older.
11953 Suggested by Paul Eggert.

11963 and ac_subst_vars be sh variables containing the list of
11964 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the

11967 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
11968 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the

11975 * bin/autoreconf.in (autoreconf): Run automake after autoconf and

11979 2002-04-23 Akim Demaille <akim@epita.fr>
11981 * bin/autoheader.in (parse_args): --warning takes an argument.

12030 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
12031 Minor spelling and grammar fixes.
12033 * doc/autoconf.texi: Follow the outline suggested in the GNU
12034 Sample Texts sections of the Texinfo 4.2 manual. Most
12035 importantly, this makes sure that the copyright notices appear in
12036 all output formats. You probably need Texinfo 4.2 to generate
12039 Fix some bugs when using "$@" when there might be zero positional
12040 arguments in cases where this matters.

12063 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
12065 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
12066 from aclocal.m4 too.
12068 2002-04-12 Akim Demaille <akim@epita.fr>
12070 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
12072 2002-04-10 Akim Demaille <akim@epita.fr>
12074 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
12075 workaround for ${1+"$@"}.
12076 * doc/autoconf.texi (Shell Substitutions): Explain it.
12077 From Oliver Kiddle and Peter Stephenson.
12079 Have M4sh perform minimal shell sanitizing.
12081 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12083 (_AS_PREPARE): this new macro.
12085 (AS_INIT): Invoke AS_SHELL_SANITIZE.
12086 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
12088 Adjust Autoconf and Autotest.
12090 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12091 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12092 * lib/autotest/general.m4 (AT_INIT): Likewise.
12093 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
12094 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
12097 Use this M4sh to generate Autoconf's shell scripts.
12099 * tests/wrapsh.as: New, precursor of wrapsh.in.
12100 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12101 on Autotest and M4sh.
12102 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12103 (wrapsh.in): New target.
12104 * bin/autoconf.as: New, precursor of autoconf.in.
12105 (autoconf.in): New target.
12107 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

12110 with indented comments in rules.
12112 2002-04-09 Andreas Schwab <schwab@suse.de>
12114 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
12115 ac_top_builddir when setting ac_abs_top_builddir.

12119 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
12120 (Portable Shell): Cross reference to Systemology.
12122 2002-04-05 Akim Demaille <akim@epita.fr>
12124 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
12125 directories when descending in a SUBDIRS.
12126 Reported by Ezra Peisach.
12128 2002-04-04 Andreas Schwab <schwab@suse.de>
12130 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
12131 contains no literal separators.
12133 2002-04-03 Akim Demaille <akim@epita.fr>
12135 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
12136 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
12137 Use dnl, not the KILL diversion.
12139 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12140 (AC_CONFIG_LINKS): here.
12142 Don't use the KILL diversion, as it kills spurious output, which
12143 results in failures being hidden.
12144 Use m4_defn where appropriate.
12145 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12146 after the second argument.
12148 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12149 syntax, as it is provided by M4sugar.
12150 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
12152 2002-04-03 Andreas Schwab <schwab@suse.de>
12154 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
12155 expanded if $# <= 2.

12171 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12173 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12174 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12175 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
12176 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
12177 (AC_C_CONST): Same.
12178 (AC_C_INLINE): Same.

12187 _AS_MKDIR_P_PREPARE.
12189 2002-03-28 Kevin Ryde <user42@zip.com.au>
12191 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12192 to avoid versions of HP C which don't allow that.
12194 2002-03-27 Paul Eggert <eggert@twinsun.com>
12196 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12197 (AS_SHELL_SANITIZE): Invoke it.
12198 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

12208 2002-03-25 Paul Eggert <eggert@twinsun.com>
12210 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12211 as POSIX requires, as it doesn't work with Zsh.
12212 * doc/autoconf.texi (Assignments): Document the problem.
12214 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12216 * doc/autoconf.texi (Limitations of Make): Mention more issue
12217 about VPATH, overriding of macros in sub-makes, and handling of
12220 2002-03-21 Paul Eggert <eggert@twinsun.com>
12222 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12223 problem with here-document buffer boundaries.
12225 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12226 when reinvoking the shell, to work around problems with installers
12227 who put strange things like "cd" commands in their environments.
12229 2002-03-19 Akim Demaille <akim@epita.fr>

12243 From Nishio Futoshi.
12245 2002-03-19 Akim Demaille <akim@epita.fr>
12247 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

12251 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12252 (Limitations of Usual Tools): Add mkdir section.
12254 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12255 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12256 back on AS_DIRNAME to compute prefixes otherwise; this is
12257 roughly what mkinstalldirs does. That way, we need not have
12258 our own filename disassembler. The old disassembler did not
12259 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12261 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12262 Create at_test_all by a series of assignments,
12263 not by a single assignment of a long string. The latter causes ksh
12264 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12265 presumably because of a buffer overrun.
12267 2002-03-14 Paul Eggert <eggert@twinsun.com>
12269 * lib/autotest/general.m4 (at_times_skip):
12270 Renamed from at_times. Now a boolean.
12271 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12272 says 'times: not found'.
12274 2002-03-14 Akim Demaille <akim@epita.fr>
12276 * bin/autoreconf.in (&study_gettextize): New.
12277 (&autoreconf): Handle newest gettextize.

12301 2002-03-11 Andreas Schwab <schwab@suse.de>

12304 does not do it if --with-lispdir is given.

12313 subdirectory should exist.
12315 2002-03-08 Akim Demaille <akim@epita.fr>
12317 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12319 2002-03-08 Akim Demaille <akim@epita.fr>
12321 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12322 aliases the actual variables, and modifications of the former
12325 2002-03-08 Akim Demaille <akim@epita.fr>
12327 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12328 because of C-c: have m4 output in tmp files, then mv them.
12330 2002-03-08 Akim Demaille <akim@epita.fr>

12353 message for LIBOBJ.

12360 2002-03-04 Akim Demaille <akim@epita.fr>
12362 * doc/autoconf.texi (Transforming Names): Equality between target
12363 and host is irrelevant.
12364 (Specifying Names, Canonicalizing): Remove all references to the
12365 backward compatibility hooks. Rather, collect them all into...
12366 (Hosts and Cross-Compilation): this new section.
12367 * doc/install.texi (System Type): Ditto.
12368 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12369 that `--host' implies cross-compilation.
12371 2002-03-04 Akim Demaille <akim@epita.fr>
12373 * doc/autoconf.texi (Evaluation Macros): New.
12374 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12376 (_m4_foreach): Define the variant with immediate evaluation so
12377 that it contains exactly the items, not an expression which
12378 evaluation is the current item.
12379 (m4_re_string, m4_re_word): Don't over quote them.
12381 2002-03-04 Akim Demaille <akim@epita.fr>
12383 Instead of having stacking `shift's evaluated at the end, let
12384 `foreach' loops immediately evaluate them.
12386 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12387 $*. This is the n-th time I change my mind, but hopefully this is
12390 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12392 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12393 it was only a hack for m4_text_wrap.
12394 (m4_car2): Remove, replaced by...
12396 (_m4_foreach): Adjust.
12397 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12398 m4_bpatsubst for clarification.

12466 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
12468 2002-02-06 Akim Demaille <akim@epita.fr>
12470 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
12471 sure not to introduce newlines in at_groups.
12472 * lib/autotest/Makefile.am (autotest.m4f): Typo.
12474 2002-02-06 Akim Demaille <akim@epita.fr>
12476 * tests/torture.at (Configuring subdirectories): Skip if aclocal
12479 2002-02-05 Paul Eggert <eggert@twinsun.com>
12481 * doc/autoconf.texi (Specific Compiler Characteristics):
12482 Describe HP-UX cc bug workaround more accurately.
12483 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
12485 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
12486 cross-compilers, too. This undoes some of the most recent change
12489 2002-02-05 Akim Demaille <akim@epita.fr>
12491 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
12492 to make sure they are up to date when `check' is run.
12494 2002-02-05 Akim Demaille <akim@epita.fr>
12496 * doc/autoconf.texi (Making testsuite Scripts): Document
12499 2002-02-05 Akim Demaille <akim@epita.fr>
12501 * lib/freeze.mk: New.
12503 2002-02-05 Akim Demaille <akim@epita.fr>
12505 Implement `autom4te --freeze'.
12507 * bin/autom4te.in (&freeze): New.
12508 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
12509 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
12511 2002-02-05 Akim Demaille <akim@epita.fr>
12513 * bin/autom4te.in (&parse_args): Implement `frozen files are
12514 optional are the sum of the previous files on the command line'.
12515 Also, pass `--reload-state=' on them, so...
12516 (handle_m4): don't.
12517 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
12518 (M4sh): Rely on M4sugar.
12519 (Autotest, M4sh, M4sugar): Use frozen files.
12521 2002-01-31 Akim Demaille <akim@epita.fr>
12523 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
12524 * doc/autoconf.texi (Initializing configure): Adjust.
12526 2002-01-30 Akim Demaille <akim@epita.fr>
12528 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
12529 alphanumeric to `-' instead of `_'.
12531 2002-01-30 Akim Demaille <akim@epita.fr>
12533 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
12534 for plain code, the other for cross-compilation code. The latter
12535 is now run with GCC only.

12543 change AC_INIT default values.
12545 2002-01-29 Akim Demaille <akim@epita.fr>
12547 * tests/torture.at (Configuring subdirectories): Use configure.in,
12548 so that aclocal 1.4 works.
12549 Reported by Alexandre Duret-Lutz and Larry Schmitt.
12551 2002-01-28 Akim Demaille <akim@epita.fr>
12553 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
12556 2002-01-28 Akim Demaille <akim@epita.fr>
12558 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12559 AUTOTEST_PATH *after* it was set.
12560 Don't put `.' in the PATH: the user should be precise and `./' if
12561 needed. In addition, given that the test suite does some `cd', if
12562 `.' is in the path, the `tested programs' sections will report
12563 programs found in the test suite's directory, while during the
12564 tests (performed in their own directory), these programs are no
12565 longer visible. In other words, the results is confusing and
12567 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

12578 2002-01-24 Akim Demaille <akim@epita.fr>
12580 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
12581 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
12582 Bourne. Use /bin/sh.
12583 From Andreas Buening.
12585 2002-01-24 Akim Demaille <akim@epita.fr>
12587 * config/config.guess, config/config.sub, config/texinfo.tex:
12588 Update from masters.

12609 2002-01-21 Akim Demaille <akim@epita.fr>
12611 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
12612 message on invalid options.
12613 * bin/autom4te.in (parse_args): Don't use
12614 Autoconf::General::getopt with non valid options.
12616 2002-01-17 Jim Meyering <meyering@lucent.com>
12618 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
12619 $ac_cv_exeext so we don't use an old, invalid, cached value.
12621 2002-01-11 Akim Demaille <akim@epita.fr>

12633 package.m4, since is really depends upon configure.ac, not
12635 * doc/autoconf.texi (testsuite Scripts): Adjust.
12636 * tests/Makefile.am (package.m4): New.
12637 EXTRA_DIST it since its a source.
12639 2002-01-06 Akim Demaille <akim@epita.fr>
12641 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
12642 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
12643 and PACKAGE_BUGREPORT from here...
12644 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
12646 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
12647 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
12648 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
12649 * tests/tools.at (autoheader): Adjust.
12650 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
12652 2002-01-06 Akim Demaille <akim@epita.fr>

12669 * doc/autoconf.texi (New Macros): Tweak wording.
12671 2001-12-14 Akim Demaille <akim@epita.fr>
12673 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
12674 trailing files, don't apply `-rf' to files which might not be
12675 created by configure (core, core.*, and *.core), but just `rm -f'.
12676 Suggested by Jonathan Kamens.
12678 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
12680 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
12682 2001-12-14 Akim Demaille <akim@epita.fr>
12684 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
12686 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

12690 abs_srcdir, top_srcpath to abs_top_srcdir.
12691 (_AC_OUTPUT_FILES): Adjust.

12702 2001-12-12 Kevin Ryde <user42@zip.com.au>
12704 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
12705 forbidden file descriptors table.
12707 2001-11-26 Akim Demaille <akim@epita.fr>
12709 * bin/autoscan.in (%c_keywords): Build it at top level.
12710 Map to 1 in order to simplify its uses.

12714 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
12715 Remove $filepath, useless.
12716 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
12717 variables, they are really part of the tokens.
12718 Split the input line on spaces and then look for tokens.
12719 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
12720 because of `lex$U.$(OBJEXT)'.
12721 (&scan_files): Use "@list" instead of join.
12722 * doc/Makefile.am (CLEANFILES): Add *.fns.
12724 2001-11-26 Akim Demaille <akim@epita.fr>

12727 Remove, replaced by...
12728 * tests/wrappl.in: Be common for all the Perl executables.
12729 In particular autoscan and autoheader want -I.
12730 * configure.ac: Adjust.
12731 * lib/autoscan/headers: errno.h is portable.
12733 2001-11-26 Akim Demaille <akim@epita.fr>
12735 * bin/autoscan.in (used): New.
12738 2001-11-26 Akim Demaille <akim@epita.fr>
12740 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
12742 (&scan_sh_file): Remove a duplicate pattern.
12743 (&check_configure_ac): Use long options.

12760 Test groups are now run two directories deeper.
12762 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
12763 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
12765 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
12766 top_srcdir, builddir and top_builddir.
12767 Use `at_*dir' relatively to the directory containing the
12768 suite, use `*dir' when relatively to the current group dir.
12770 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
12772 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
12773 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
12774 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
12777 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12779 * doc/autoconf.texi (Using System Type): Add an example of `case
12780 $host' usage so people quit using `case $target' everywhere.
12782 2001-11-22 Akim Demaille <akim@epita.fr>
12784 * doc/autoconf.texi (Installation Directory Variables): Englishoes
12785 spotted by Jim Meyering.
12787 2001-11-16 Paul Eggert <eggert@twinsun.com>
12789 This patch implements a `long double' suggestion by Oliver Kiddle.
12791 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
12792 static, to catch errors if the value isn't known at compile-time
12793 and the compiler supports dynamic arrays. Change its name from
12794 `_array_' to `test_array' to avoid potential name clashes.
12795 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
12796 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
12797 better than double. Catch a bug in GCC 2.95.2 x86.
12798 * doc/autoconf.texi (C Compiler): Document the above.
12801 2001-11-13 Akim Demaille <akim@epita.fr>
12803 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
12805 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
12807 2001-11-13 Akim Demaille <akim@epita.fr>
12809 * lib/autotest/general.m4 (AT_INIT): After having run the test
12810 group, go back to the initial directory, not to at_suite_dir.
12812 2001-11-13 Akim Demaille <akim@epita.fr>
12814 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
12815 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
12816 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
12818 (AT_CHECK_CONFIGURE): Use absolute paths.
12819 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
12820 The problem is still the old one: there is no means in M4 (that I
12821 know about) to create a defining macro, because there is no means
12822 to create `$1' etc., therefore, the defining macro ``swallows''
12823 all the arguments meant to the defined macro.
12825 2001-11-13 Akim Demaille <akim@epita.fr>
12827 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
12828 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
12830 * tests/aclocal.m4: Remove, as it is no longer used.
12832 2001-11-13 Akim Demaille <akim@epita.fr>
12834 * lib/autotest/general.m4: Change `tests?' into `groups?' in
12835 variable names when referring to a single test group, or to
12836 `suite' when referring to the whole test suite.
12837 `at_last_test' is removed: m4 compute at_format itself.
12838 (at_stdout, at_stder1, at_stderr): New variables.
12839 (AT_CHECK): Use them.
12841 2001-11-13 Akim Demaille <akim@epita.fr>
12843 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
12845 Create `testsuite.dir/003/run' instead of `testsuite.003'.
12846 Do it as soon as a test fails, don't wait till the end of the test
12848 Don't remove $as_me.[0-9]*, since these files no longer exist.
12850 2001-11-13 Akim Demaille <akim@epita.fr>
12852 * tests/tools.at: Use absolute paths, since we are no longer run
12855 2001-11-13 Akim Demaille <akim@epita.fr>
12857 Now that tests are running in their own private dir, there is no
12858 need to list the files to remove at the end of tests groups.
12860 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
12861 (AT_data_files, at_data_files): Remove.
12862 (AT_CLEANUP, AT_DATA): Simplify.
12864 Remove the group dir if !debug && !failed.
12865 * tests/atspecific.m4: Adjust.
12867 2001-11-13 Akim Demaille <akim@epita.fr>
12869 Start a new layout for Autotest: `testsuite' creates
12870 `testsuite.dir' in which the at-check-line etc. files are to be
12871 found, and `testsuite.dir/003' where the test group 3 is run.
12873 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
12874 at_check_line_file, at_format, at_test_normalized, at_group_dir
12876 Create the directories.
12877 Use absolute paths for at- files.
12878 (AT_CHECK): Adjust.
12880 2001-11-11 Michael Matz <matz@kde.org>
12882 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
12884 (m4_car): Properly quote arguments.
12886 2001-11-13 Akim Demaille <akim@epita.fr>
12888 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
12889 with stricter rules on LIBOBJS.
12891 2001-11-12 Paul Eggert <eggert@twinsun.com>
12893 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
12894 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
12897 2001-11-12 Akim Demaille <akim@epita.fr>
12899 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
12901 2001-11-12 Akim Demaille <akim@epita.fr>
12903 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
12904 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
12905 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12906 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
12907 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
12908 specify to what the macro should be defined (typically to 1).
12910 2001-11-12 Akim Demaille <akim@epita.fr>
12912 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
12915 2001-11-12 Akim Demaille <akim@epita.fr>
12917 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
12918 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
12919 definition used by Automake where LEX is +/- "${missing} lex" and
12920 `missing' itself contains variables.
12922 2001-11-12 Akim Demaille <akim@epita.fr>
12924 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
12925 Now that M4sh pushes BODY, the comments were output at the end of
12928 2001-11-08 Akim Demaille <akim@epita.fr>
12930 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
12931 that we can trace macros from aclocal.m4.
12932 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
12933 obsoleted, and redirect to the former anyway.
12934 Reported by Ralf Corsepius.
12936 2001-11-08 Akim Demaille <akim@epita.fr>
12938 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
12939 processed only if present.
12940 * tests/torture.at (Configuring subdirectories): Use autoreconf
12941 instead of successive calls to autoconf.
12942 Add a nonexistent subdirectory to exercise the patch above.
12943 Reported by Ralf Corsepius.
12945 2001-11-08 Kevin Ryde <user42@zip.com.au>
12947 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
12948 doesn't accept .S files.
12950 2001-11-07 Akim Demaille <akim@epita.fr>
12952 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
12953 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
12954 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.

12970 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
12972 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing

12998 2001-11-03 Akim Demaille <akim@epita.fr>

13008 Reported by Ezra Peisach.
13010 2001-11-03 Akim Demaille <akim@epita.fr>
13012 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13013 passed on command line, defaulting to ./configure.ac if present.
13014 (&maybe_autoreconf, File::Find): Remove, unused.
13015 (&autoreconf): If autoconf is not used, don't try to trace.
13017 2001-11-02 Akim Demaille <akim@epita.fr>

13021 2001-11-02 Akim Demaille <akim@epita.fr>
13025 2001-11-02 Akim Demaille <akim@epita.fr>

13028 * config/lispdir.m4: Update from masters.
13029 * configure.ac: Bump to 2.52f.
13031 2001-11-02 Akim Demaille <akim@epita.fr>

13038 2001-11-01 Paul Eggert <eggert@twinsun.com>
13040 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13041 be invoked before _AS_LINENO_PREPARE.
13042 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13043 than character ranges.
13045 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13046 invoking AS_BASENAME. Set the locale variables to 'C' if
13047 possible, as POSIX requires this to get the traditional
13049 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13051 2001-10-31 Paul Eggert <eggert@twinsun.com>
13053 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13054 with {}, as that triggers a bug in Bash 2.05.
13056 (_AS_LINENO_PREPARE): Use Sed rather than
13057 Awk. Fix the sed prepass to work even if there are multiple
13058 instances of $LINENO on the same line. Do not substitute for
13059 other variables like $LINENOT. Do not check file dates; such a
13060 check is unreliable on sufficiently fast machines, and removing
13061 the check makes the code simpler and more reliable. Check for
13062 output and chmod failures.
13064 * doc/autoconf.texi (Special Shell Variables): Document
13067 2001-10-31 Akim Demaille <akim@epita.fr>

13074 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13075 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13076 provided, while it is optional.
13077 * configure.ac: Adjust.
13079 2001-10-26 Paul Eggert <eggert@twinsun.com>
13081 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13082 lib/Autom4te/Struct.pm:
13083 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13086 * doc/autoconf.texi (Special Shell Variables): Document some
13087 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13089 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13090 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13091 eval $LINENO is not portable in practice.
13093 2001-10-24 Akim Demaille <akim@epita.fr>
13095 * lib/Autom4te/General.pm (backname): New.
13097 2001-10-24 Akim Demaille <akim@epita.fr>

13107 2001-10-22 Paul Eggert <eggert@twinsun.com>
13109 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13110 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13111 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13112 POSIX decided to standardize on the int flavor of strerror_r.
13113 Always do char* test, as there's no reason not to.
13114 Assign to a char* var, to catch strerror_r that returns int*.
13116 * doc/autoconf.texi (Particular Functions):
13117 Document the above changes. Also, document the fact that
13118 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13120 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13122 2001-10-20 Akim Demaille <akim@epita.fr>

13125 the executable was missing from the log.
13127 2001-10-20 Akim Demaille <akim@epita.fr>
13129 * lib/Autom4te/General.pm (&update_file): If destination is
13130 unchanged, remove the source.

13132 * bin/autoreconf.in: No longer support --m4dir.
13133 (&autoreconf): Display the full path of the configure.ac we are
13135 Trace it only once.
13136 Be sure to honor --force with gettextize.
13137 Always run aclocal.
13138 * doc/autoconf.texi: Adjust.
13140 2001-10-20 Akim Demaille <akim@epita.fr>
13142 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13144 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13145 `intl' is already present, as it refuses unless --force.
13146 (&parse_args): Use -I, --include instead of the old Autoconf
13148 ($localdir, $autoconf_dir): Remove.
13150 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13152 2001-10-19 Jens Petersen <petersen@redhat.com>
13154 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

13173 configure.ac being studied.
13175 2001-10-18 Paul Eggert <eggert@twinsun.com>
13177 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13178 long, to work around a bug in the HP C compiler version HP92453-01
13181 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13182 (AS_BASENAME_EXPR): New macro.
13183 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13184 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13185 and fall back on 'sed' only if the other two fail. This makes
13186 AS_BASENAME act more like AS_DIRNAME.
13187 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13188 contains white space.
13189 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13190 Use AS_DIRNAME, since I think it's now DOS-friendly.

13203 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

13243 bother with $force since...
13244 * lib/Autom4te/General.pm: does.
13246 2001-10-08 Akim Demaille <akim@epita.fr>
13248 * bin/autoreconf.in: Rewrite in Perl.
13249 * configure.ac: Adjust.

13318 include handle the m4_pattern_*, no longer push the

13332 shell does not support LINENO, and if CONFIG_SHELL is unset or
13333 empty, and if we can find a shell that does support LINENO,
13334 then set CONFIG_SHELL to that shell and then re-execute
13335 ourselves with CONFIG_SHELL.
13337 2001-10-05 Paul Eggert <eggert@twinsun.com>
13339 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
13340 doesn't exist. Remove *.tmp, as a .tmp file is created during the

13410 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
13411 Don't use nested parenthesization. This patch was originally
13412 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
13413 but somehow it didn't get incorporated then.
13414 * doc/autoconf.texi (Limitations of Usual Tools):

13420 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13421 Check for `expr' arithmetic overflow, and for compilation failure,
13422 and invoke a new argument $4 if either is discovered.
13423 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13424 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
13426 2001-09-28 Akim Demaille <akim@epita.fr>
13428 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

13653 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
13655 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13656 Do not pass a first argument with leading '-'
13657 to expr, by parenthesizing initial integers that might be negative.
13659 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
13660 now merely checks whether it is an error to pass an argument
13663 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
13664 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
13665 whether it is a (compile-time) error to pass an argument to

13683 Add test for AS_BASENAME.
13684 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
13685 added test. It now correctly handles /1/2/3/, returning '3' not ''.
13686 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
13687 * tests/base.at: Fixed the expected responses. The old ones were
13689 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
13690 the documentation claims it should (and how it behaved in 2.13).
13692 2001-09-18 Akim Demaille <akim@epita.fr>
13694 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
13695 the AC_CONFIG_COMMANDS invocation.

13699 No longer to be shipped.

13705 the only optional argument is the name of the test suite.
13706 Expect `package.m4' to define the package signature.
13707 * lib/autom4te.in (Autotest): Add `package.m4?'.
13708 * tests/Makefile.am (package.m4): New.

13728 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13729 Always include <stdio.h> and <stdlib.h>. Evaluate
13730 the expression in an extra function before these includes. Call
13731 fprintf "%d" only after ensuring the argument is of type 'int'.
13732 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
13734 2001-09-17 Paul Eggert <eggert@twinsun.com>
13736 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
13737 or CFLAGS=-O5. In that case, the linker has a relaxed view of
13738 fatal errors, and AC_CHECK_LIB causes it to include libraries even
13739 when they don't exist.
13741 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
13742 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
13745 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
13746 version with the version used by fileutils 4.1, except use

13792 * lib/autotest/general.m4 (AT_INIT): Create and remove
13793 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

13798 * tests/mktests.sh: Don't output banners for empty test files.

13897 to avoid GCC warnings.
13900 2001-09-05 Akim Demaille <akim@epita.fr>
13902 * bin/autom4te.in: --language is -l, not -s.
13904 2001-09-05 Akim Demaille <akim@epita.fr>
13906 Be ready to handle filenames as stupid as `dnl.at', for if even
13907 the maintainer is dumb enough to do that...
13909 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
13910 excellence in M4 quotation: consider `__file__' is active.
13912 And BTW, when invoking m4, pass the --include in the right order:
13915 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

13938 2001-09-05 Akim Demaille <akim@epita.fr>
13940 CVS GNU M4 doesn't like `undefine(undefined)'.
13942 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
13943 New, extracted from main.
13944 Use IO::File wherever possible.
13945 (input.m4): Be constant, use -I instead of hard coding $tmp.
13946 Therefore be a quoted heredoc.
13947 Don't invoke `_au_disable', since ac was not loaded, but just

13973 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
13975 2001-08-31 Akim Demaille <akim@epita.fr>
13977 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
13978 (testsuite Scripts): There is no such thing as `atconfig.in'.
13979 And actually one diagram is missing: test suite runtime.
13981 2001-08-31 Akim Demaille <akim@epita.fr>
13983 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
13986 2001-08-31 Akim Demaille <akim@epita.fr>
13988 * bin/autoupdate.in (@include): `installcheck' revealed the path
13989 to m4sugar was lacking!
13991 2001-08-31 Akim Demaille <akim@epita.fr>
13993 * man/Makefile.am (.x.1): We really have to pass

14004 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
14005 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
14006 Use directly autom4te, not autoconf.

14031 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
14032 (autoheader): Pass --force since the test suite goes too fast for
14034 Adjust to the new autoheader messages.

14050 `autoheader: `config.hin' is created'.
14051 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14053 2001-08-31 Akim Demaille <akim@epita.fr>

14061 Map --localdir, --autoconf-dir onto it.
14062 Forward autom4te's options instead of interpreting them.

14064 There is no such envvar since the inception of autom4te.cfg.
14065 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14066 * bin/autoupdate.in: Adjust, and perform more control.

14068 * tests/autoconf: Dittowise.
14070 2001-08-31 Akim Demaille <akim@epita.fr>

14086 * lib/Autom4te/General.pm (&find_peer): Remove.
14087 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14088 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14089 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14090 find the executables for it.
14091 * tests/Makefile.am: Major cleanup. Too lazy to document...
14092 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14094 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14095 indeed related to running the test suite, while passing
14096 --autoconf-dir and others is related to running non installed
14097 Autoconf executables. So don't do that, leave it to...
14098 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14099 * tests/autoscan: New.
14100 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

14117 Suggested by Paul Eggert.
14119 2001-08-29 Akim Demaille <akim@epita.fr>
14121 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
14122 download in a tmp dir.
14124 2001-08-29 Akim Demaille <akim@epita.fr>
14126 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

14146 foo=`(command) 2>/dev/null`

14297 the name of the directory they're in, instead of the filename,

14386 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
14387 * NEWS, README, README-alpha, TODO, tests/README: This package is
14388 `Autoconf', not `autoconf' (the executable).
14390 2001-08-20 Akim Demaille <akim@epita.fr>
14392 Info readers seem to need `Index' in the index node title :(
14394 * doc/autoconf.texi: Reverse the 2001-08-15 change which
14395 simplified index node names.

14444 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
14445 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

14508 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
14509 `$0.log' as for projects where testsuite is in src, we'd have

14526 * doc/autoconf.texi: Work around Texinfo buglets.
14527 (Transformation Rules): One example is enough, users are expected
14528 to have their brains on. And BTW, use DESTDIR.
14529 (dvar): New macro. Use it.
14531 2001-08-17 Akim Demaille <akim@epita.fr>
14533 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

14585 * tests/Makefile.am: Use a clean-local rule to remove
14586 autom4te.cache (it's a directory, not a file.
14587 * Makefile.am: Ditto (but maintainer-clean-local).
14589 2001-08-15 Akim Demaille <akim@epita.fr>
14591 * bin/autom4te.in (@m4_warning): New.
14592 (&handle_m4): Use it.
14593 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
14594 warnings are issued at each run.
14595 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
14596 is in the src tree.
14598 2001-08-15 Akim Demaille <akim@epita.fr>
14600 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
14601 don't waste time running `autoupdate --version' works.
14602 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
14604 2001-08-13 Akim Demaille <akim@epita.fr>

14661 * tests/semantics.at (AC_C_BIGENDIAN): New test.
14663 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
14665 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
14666 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
14667 * doc/autoconf.texi (C Compiler Characteristics): Update
14668 documentation for AC_C_BIGENDIAN.
14670 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>

14673 magic values from an object file when cross-compiling.
14674 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
14676 2001-08-10 Akim Demaille <akim@epita.fr>
14678 * bin/autom4te.in (&handle_output): Don't use `grep' with side
14680 Suggested by Russ Allbery.
14682 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
14684 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
14685 current $prefix to the sub-configures.
14687 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
14689 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
14690 extension (needed on BeOS). Reported by Guido van Rossum.
14692 2001-08-09 Akim Demaille <akim@epita.fr>
14694 * bin/autom4te.in ($icache): Load it only if older than autom4te.
14696 2001-08-07 Akim Demaille <akim@epita.fr>
14698 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
14700 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
14701 No need to remove the files before and after the each test, before
14702 each test and at the end of the suite is enough.
14703 Display only the children `times', not the shell's.
14704 If the test failed or was skipped, at-times is not available.
14706 2001-08-07 Akim Demaille <akim@epita.fr>
14708 Always produce testsuite.log, including when there are no
14709 failures. This helps getting information on skipped tests, and
14710 duration of the tests. Err, implement the latter btw.
14712 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
14713 Dump information on the first run of each test.
14714 (AT_CLEANUP): Create `at-times' containing the duration of the
14717 2001-08-07 Akim Demaille <akim@epita.fr>
14719 The use of `dumpstat' revealed that `len' was used although it
14720 should not. m4_text_wrap was using it, but in the Autoconf world
14721 where it is legal. Hence (i) test M4sh in its own world, not
14722 Autoconf's, and (ii), ahem, fix the bug :)
14724 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
14725 does not like `' instead of [].
14726 (AT_INIT): Forbid `^_?AT_'.
14727 And don't output such tokens.
14728 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
14729 `script.as', and `autom4te.cache'.
14730 Remove `empty' and `macro' which are no longer used.
14731 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
14732 * tests/m4sugar.at: Use it.
14733 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
14735 2001-08-07 Akim Demaille <akim@epita.fr>
14737 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
14739 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
14741 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
14743 2001-08-04 Akim Demaille <akim@epita.fr>
14745 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
14746 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
14748 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
14749 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
14750 (AC_F77_MAIN): Likewise.
14752 2001-08-04 Akim Demaille <akim@epita.fr>
14754 Don't rely on M4sugar outputting the patterns in files, since we
14755 might process the output _without_ running m4, hence without these
14758 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
14759 * bin/autom4te.in (@Request::includes): Remove, unused.
14760 (@Request::source): Rename as...
14761 (@Request::input): this.
14762 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
14763 (&handle_output): Fetch the patterns from the traces.
14764 `$forbidden' and `$allowed' are constant: use m//o.
14765 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
14766 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
14768 2001-08-04 Akim Demaille <akim@epita.fr>
14770 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
14771 autoconf', i.e., in addition to caching traces, cache the output.
14773 * bin/autom4te.in (Request::cache): Rename as...
14774 (Request::id): this.
14775 ($cache, $icache, $tcache, $ocache): New.
14776 (&handle_m4): Save M4 output in the cache instead of $tmp.
14777 (&handle_output): Adjust.
14778 (&up_to_date_p): Check that the output cache is up to date too.
14779 (top level): Run `&handle_m4' iff force or the cache is invalid.
14780 Run `&handle_output' if the output cache is more recent.
14782 2001-08-04 Akim Demaille <akim@epita.fr>
14784 * bin/autom4te.in ($force): New.
14785 (&parse_args, &print_usage): -f, --force is a new option.
14786 (&handle_output): CPP directives might have spaces after `#'.
14787 (&parse_args): The first file only can be frozen.
14789 2001-08-04 Akim Demaille <akim@epita.fr>
14791 Don't let autom4te compute the `include' traces several times:
14792 first check that the trace cache file is up to date, and then
14793 compare its timestamp with that of the output.
14795 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
14796 the preamble. Don't require 5.005 as Autom4te::General does it,
14797 and better yet (use `use', not `require'!).
14798 * lib/Autom4te/Struct.pm: Rename the last occurrences of
14799 Class::Struct as Autom4te::Struct.
14800 * lib/Autom4te/General.pm (File::stat): Use it.
14801 (&mtime): New, export it.
14802 * bin/autom4te.in: Use it.
14803 Declare `$req' is invalid if it is outdated.
14804 Don't declare it valid before saving it if something went wrong.
14806 2001-08-04 Akim Demaille <akim@epita.fr>
14808 Autom4te shall not encode Autoconf data, and preselecting traces
14809 must be proposed to the users.
14811 * bin/autom4te.in (@required_trace): Remove.
14813 (&parse_args, &print_usage): -p, --preselect is a new option.
14814 (&up_to_date_p): Adjust.
14815 * bin/autoconf.in: Preselect some Autoconf macros.
14817 2001-08-04 Akim Demaille <akim@epita.fr>

15317 dummy alternate main is required even if the user provides her own
