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

608 * build-aux/config.guess, build-aux/config.sub,
609 build-aux/texinfo.tex: Sync from gnulib.
610 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
613 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
615 * doc/autoconf.texi (Particular Programs): Do not mention the
616 Autoconf version in which the AC_PROG_INSTALL change was done.
617 Suggested by Paul Eggert.
619 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
621 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
622 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
623 mode, we change to the source directory, also set $ac_pwd so we
624 do not go back to the build tree for the next config subdir.
625 * tests/torture.at (Deep Package): Extend test to contain two
626 config subdirs on the top level.
628 Fix parallel `maintainer-check'.
629 * Makefile.am (maintainer-check-tests): Depend on `all'.

631 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
633 (maintainer-check): Serialize the testsuite runs.
635 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'

657 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
659 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
660 check_SCRIPTS. Building the wrappers for `all' allows help2man
661 to use them for the manpages.
662 Report by Benoit Sigoure.
664 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
666 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

678 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
679 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
680 (m4_require): Use m4_do, not m4_join.
682 Fix some whitespace tests on cygwin.

684 font-lock. Create $TMPDIR before it might be used.
686 Fix spurious testsuite failure with M4 1.4.11.
687 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
690 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
691 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
692 (m4_require): Avoid extra macro calls.
694 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
696 * tests/torture.at (srcdir): Fix quoting.
698 Do not pass top_srcdir to configure scripts in testsuite.
699 * tests/autotest.at (srcdir propagation): Copy install-sh to
701 (my only test): Drop setting of `top_srcdir'.
702 * tests/base.at (Input/Output): Likewise.
703 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
704 config.guess, and config.sub to test source tree.
705 Drop AC_CONFIG_AUX_DIR setting.
706 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
707 * tests/torture.at (Substitute a 2000-byte string): Drop
708 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
709 (Substitute a newline, datarootdir workaround): Likewise.
710 (Define a newline): Adjust for linenumber changes in configure.ac.
711 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
713 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
714 if `pwd` contains whitespace.
716 Quote $abs_top_srcdir in tests.
717 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
718 * tests/tools.at (Syntax of the shell scripts): Likewise.
720 * tests/m4sh.at (LINENO): Quote $0.
722 Fix testsuite program wrapper for whitespace in `pwd`.
723 The problem here is that the usual mantra is that command
724 variables can contain arguments, thus we cannot just escape
725 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
726 $top_builddir/tests directory early in $PATH, so that the
727 wrappers are found by their plain name.
728 * tests/wrapper.as: Put $testdir early in $PATH.
729 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
731 Proper config.status --file/--header and $srcdir escaping.

737 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
739 Fix Autotest for whitespace in `pwd`.
740 * lib/autotest/general.m4 (AT_INIT)
741 <at_func_create_debugging_script, Driver Loop>:
743 * tests/autotest.at (whitespace in absolute testdir): New test.
745 * lib/autom4te.in: Quote @datadir@.
747 Proper file name escaping in Autoconf programs and Perl modules.
748 This includes escaping of characters special to the shell
749 as well as special to Perl, e.g., leading `<' or `>'.
750 For example, when $file starts with `>', `open ">$file"'
751 wrongly tries to append to a different file.
752 * bin/autoconf.as: Fix quoting for autom4te options.
753 * lib/Autom4te/General.pm (shell_quote): New function, taken
754 from coreutils, written by Jim Meyering.
756 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
758 * bin/autoreconf.in (parse_args): Likewise.
759 * bin/autoscan.in (main): Likewise.
760 * bin/autoupdate.in (main): Likewise.
761 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
762 * bin/ifnames.in: Likewise, XFile usage fixes.
763 * tests/tools.at (autom4te and whitespace in file names): Extend
764 test. Test twice, with special characters allowed on w32, and the
765 rest. Test leading and trailing whitespace, for `open_quote'.
766 (autotools and whitespace in file names): New, analogous test.
767 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
768 by Russ Allbery and Eric Blake.
771 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
772 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
773 * lib/Autom4te/FileUtils.pm (open_quote): New function.
774 (update_file, contents): Use it.
776 * Makefile.am (autom4te-update): Rewrite for git.
778 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
780 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
783 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
784 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
786 2007-12-04 Eric Blake <ebb9@byu.net>
788 Manually resync with gnulib, since 'make cvs-update' no longer works.
789 * build-aux/config.guess: New upstream version.
790 * build-aux/config.sub: Likewise.
792 When using older automake, don't downgrade build-aux/texinfo.tex.
793 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
794 * doc/Makefile.am (TEXINFO_TEX): Add.
796 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
798 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
799 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
800 #undef as this runs afoul of our new way of creating config.h.
801 Problem reported by Jim Meyering in
802 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
804 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
806 Fix autom4te for unusual characters in input file names.
807 * bin/autom4te.in (files_to_options): Quote active characters
809 * tests/tools.at (autom4te and white space in file names):
812 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
813 Document that Tru64 awk always splits $0.
815 2007-11-24 Stepan Kasal <kasal@ucw.cz>
817 * lib/autotest/general.m4 (AT_INIT): Do not extract the
818 `#AT_STOP_...' line at the end of each test.
820 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
822 * lib/autotest/general.m4 (AT_INIT): For awk line number
823 extraction script, ensure `$at_group' has a defined value
824 even for the empty set, and properly quote its usage inside
827 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
829 * doc/autoconf.texi (Shell Functions): New chapter. Document
830 IRIX sh $0 issue in functions, move content from ...
831 (Portable Shell): ... here.
832 (Shell Script Compiler): Note that shell functions are not
833 totally unportable any more.
835 2007-11-22 Stepan Kasal <kasal@ucw.cz>
836 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
838 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
839 extracting the line numbers of the last needed test.
841 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
843 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
846 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
848 Fix IRIX testsuite debugging failures: $0 in functions.
849 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
850 Do not use $0 inside a function, as IRIX sh will set that to the
851 function name rather than the script invocation name.
853 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
854 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
856 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
857 to extract test scripts.
858 (AT_INIT): Extract and cache test script line numbers.
860 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
862 * lib/autotest/general.m4: Revert 2007-11-15 patch and
863 subsequent fixups; the awk -> here-document conversion trashes
864 performance too much with AIX sh.
866 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
868 * tests/local.at: Do not test m4, perl with AT_TESTED.
870 Diagnose and guard against write errors dealing with config.status.
871 The general idea is this: all write failures from `configure'
872 writing `config.status' are indicated by $ac_write_error, which
873 is only checked at the end. This is safe because config.status
874 code is not executed before the file is complete. Other write
875 failures, be they inside config.status, or in sub shell/awk
876 scripts spawned from configure or config.status, typically need
877 earlier checking, as their results are used right afterwards.
878 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
879 before writing config.status, check afterwards.
880 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
881 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
882 Set `ac_write_error' for write failures to config.status. Barf
883 upon write failures to temporary files.
884 Adjust note about closing and reopening the here-document.
885 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
886 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
887 reopening the here-document.
888 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
889 Ensure `ac_write_error' does not escape into config.status.
890 Also, add a couple of code paths not yet exercised in the test
891 suite: a config file with input from stdin, and a config header
893 Suggestion for catching write errors by Bruno Haible.
895 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
897 Avoid error with Tru64 awk and testsuite lines with many words.
898 * lib/autotest/general.m4 (AT_INIT): In the awk script that
899 reads the testsuite, set the field separator to an unusual value,
900 in order to not run over the limit of 199 fields. Tru64 4.0D awk
901 even splits the input if $i, i>0, was never accessed in the script.
903 Revert 2007-10-17 change.
904 * TODO: Multiline args in config files and headers mean something
905 different and are not fixed, see
906 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
907 Report by Stepan Kasal.
909 * doc/autoconf.texi (Generic Programs): Fix typo.
911 2007-11-16 Stepan Kasal <kasal@ucw.cz>
913 AC_*_TOOL does not canonicalize the prefix
914 * doc/autoconf.texi (Generic Programs): Do not say that
915 the *_TOOL macros canonicalize, they simply use the `host_alias'.
917 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
919 Diagnose write errors in config.status instantiations.
920 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
921 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
923 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
924 Extend test to also check for some write error failures, using...
925 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
926 Report by Bruno Haible.
929 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix

945 Remove at-test-source files together with the $at_group_dir.
946 * tests/autotest.at (Long test source lines): New test.
948 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
950 Shell functions and variables may share a namespace.

956 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
959 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
961 * lib/autoconf/status.m4: Fix a couple of comment typos.
963 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
965 2007-11-13 Jim Meyering <meyering@redhat.com>
967 Clean up the rule to create "expr".
968 * tests/Makefile.am (expr): Don't redirect directly to target.
969 Redirect just once, not for each echo statement.
970 Use $@, not literal "expr".
972 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
974 Don't worry about preprocessor when testing long long.
975 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
976 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
977 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
978 These no longer check for preprocessor flaws.
979 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
980 Do not check for preprocessor flaws.
982 2007-11-13 Jim Meyering <meyering@redhat.com>
984 Adapt dependencies, now that a version change doesn't modify configure.ac
985 * GNUmakefile: Remove "make clean" kludge.
986 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
988 Don't redirect directly to target.
989 Use $@, not literal "version.m4".
991 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
993 * doc/autoconf.texi (Making testsuite Scripts): Document
994 ":;{" shorthand as in previous patch.
996 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
998 * doc/autoconf.texi (Limitations of Builtins): Document problem
999 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1001 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1002 Use ":;{" shorthand.
1003 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1005 2007-11-12 Jim Meyering <meyering@redhat.com>
1007 Add more non-srcdir build support.
1008 * GNUmakefile (dummy): Split a long line.
1009 Add -v option to autoreconf invocation.
1011 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1012 * GNUmakefile (dummy): Remove INSTALL.
1014 Remove racy commands to build scripts in bin/ and tests/.
1015 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1016 are guaranteed to be built, remove the rules that tried to build
1017 them. Before, with a parallel build, these rules could lead to
1018 two processes writing tests/wrapper.in concurrently.
1020 Build in man/ only *after* building in bin/ and tests/.
1021 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1022 in both bin/ and tests/.
1024 Accommodate non-srcdir build-from-checkout.
1025 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1026 Use git's --git-dir=$srcdir/.git option.
1027 Add quotes, in case tarball_version_file contains shell meta-characters.
1028 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1029 * configure.ac: Pass "." to git-version-gen.
1031 Avoid spurious test failures due to version skew.
1032 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

1059 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1061 Ignore configure --help* errors due to LINENO-impaired shells.
1062 * tests/torture.at (Configuring subdirectories, Deep Package):
1063 In the --help* tests in read-only trees, make `.' temporarily
1064 writable again for the `stderr' file, and ignore errors due to
1065 the attempt to write configure.lineno.
1066 Report by Patrick Welche.
1068 2007-11-10 Jim Meyering <meyering@redhat.com>
1070 Generate package.m4 in build-dir, not srcdir.
1071 * tests/Makefile.am (package.m4): Adjust target.
1072 Don't redirect directly to $@.
1073 (CLEANFILES): Add package.m4.
1074 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1076 When running $(AUTOTEST), search "." before searching $(srcdir).
1078 Avoid a race condition that would make parallel "distclean" fail.
1079 * tests/Makefile.am (distclean-generic): Replace the default,
1080 automake-provided rule with an identical one, but with an additional
1081 dependency on distclean-local. Simply adding the dependency would
1082 cause automake not to emit the rule at all.
1083 * BUGS: Building with -jN works, now.
1085 Distribute git-version-gen.
1086 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1087 since GNUmakefile is distributed, and requires it for dist* rules.
1089 Remove two more generated files from version control.
1090 * INSTALL: Remove generated file.
1091 * lib/autoscan/autoscan.list: Remove generated file.
1093 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1095 * GNUmakefile (PATH): Remove stray apostrophes; they become
1096 part of PATH, which isn't wanted here.
1098 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1100 New config files output variable `top_build_prefix'.
1101 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1103 * doc/autoconf.texi (Preset Output Variables): Document it.
1105 Report by Bob Friesenhahn.
1107 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1108 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1109 function, to parametrize arithmetic with expr vs. the shell.
1110 Use it where possible.
1111 Suggestion by Benoit Sigoure.
1113 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1115 Adjust the documentation of autotest WRT atlocal.
1116 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1117 when using Automake, to write a rule to produce atlocal, since it's
1118 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1119 distributed, not atconfig.in.
1121 2007-11-04 Eric Blake <ebb9@byu.net>
1123 Update list information.
1124 * README: Mention new autoconf-commit list.

1131 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1133 * build-aux/.gitignore: Ignore mkinstalldirs.
1135 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1137 2007-11-03 Jim Meyering <meyering@redhat.com>
1139 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1140 * build-aux/git-version-gen: This syncs from coreutils.
1142 Adjust the build procedure so "make check" works reliably.
1143 * README-hacking: Include an extra step between "make" and
1144 "make check" to ensure that the latter passes.
1146 Use just-built tools, when possible.
1147 * GNUmakefile (PATH): Set and export here, ...
1148 (dummy): ... rather than here.
1150 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1151 and Andreas Schwab <schwab@suse.de>
1153 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
1156 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1158 * configure.ac (AC_PREREQ): Require version 2.60, for
1159 AC_PROG_SED, AC_PROG_GREP.
1161 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>

1176 Reported by Ralf Wildenhues.
1178 2007-11-03 Jim Meyering <meyering@redhat.com>
1180 Remove automake-provided files from version control.

1182 * build-aux/install-sh: Remove file.
1183 * build-aux/missing: Remove file.
1184 * build-aux/mdate-sh: Remove file.
1185 * build-aux/.gitignore: New file.
1186 Suggestion from Ralf Wildenhues.
1188 2007-11-03 Eric Blake <ebb9@byu.net>
1190 Adjust version comparison to account for git snapshot numbers.
1191 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a

1197 2007-10-30 Bruno Haible <bruno@clisp.org>
1199 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1200 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1201 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1202 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1203 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1204 Suggested by Paul Eggert.
1206 2007-10-28 Jim Meyering <meyering@redhat.com>
1208 * README-hacking: Autoconf, Automake, and Perl are required to build.
1209 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1211 2007-10-28 Jim Meyering <meyering@redhat.com>
1213 README-hacking: Recommend running autoreconf -vi.
1214 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1215 so that we use just-built tools when they're available.
1216 Suggestions from Ralf Wildenhues.
1218 2007-10-28 Jim Meyering <meyering@redhat.com>
1220 Make inter-release --version output more useful.
1222 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1223 which indicates that it is built using the 19th change set
1224 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1225 is a prefix of the commit SHA1.
1226 * build-aux/git-version-gen: New file.
1227 * configure.ac: Run it to set the version.
1228 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1229 * Makefile.am (dist-hook): Arrange so that .version appears only
1230 in distribution tarballs, never in a checked-out repository.
1231 * .gitignore: Add .version here, too. Just in case.
1232 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1233 not configure.ac, now that the version number changes automatically.
1235 Ensure that $(VERSION) is up to date for dist-related targets.
1236 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1237 git-version-gen doesn't match $(VERSION), but only for dist targets.
1239 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1279 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1281 Don't check for bug in HP-UX 11.00 cpp.
1282 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
1283 Use -1ull rather than -1u, since that causes problems with gnulib; see
1284 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

1302 escaping of backslash in here-documents.
1304 Fix `Deep Package' test failure on FreeBSD.

1306 unnecessarily. Do not try running `/bin/sh configure' with a
1307 configure script to be found in $PATH, if the shell does not do
1308 this resolution. Fixes test failure on FreeBSD.
1310 Fix config header generation with AIX awk.
1311 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
1312 script, use helper array D_is_set, as `" 0"' does not evaluate
1313 to true for AIX awk.

1354 array of banner text from a special diversion.
1355 <PARSE_ARGS_END>: No longer need awk to find banners.
1356 <TESTS>: Banners are no longer processed by main driver loop, so
1357 we no longer need case statement.

2534 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
2535 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
2536 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
2537 works but the latter doesn't, then it's a valid type.
2538 This lets people use function types and so forth.
2539 For C++ there doesn't seem to be a simple solution, so leave it alone.
2540 (AC_CHECK_SIZEOF): Allow argument to be a variable.
2541 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
2542 AC_CHECK_TYPE; that wasn't documented or necessary.
2544 2007-04-11 Stepan Kasal <kasal@ucw.cz>
2546 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

2630 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
2631 Reindent for sanity's sake.
2633 2007-02-24 Eric Blake <ebb9@byu.net>

2713 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
2714 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
2715 substitution will still be done by the special code.

2737 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2739 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
2740 early on the reader side, drop stderr of the input to avoid
2741 `broken pipe' error output; this may happen even with shell
2742 builtin `echo' of some bash versions. Reports by Ian Macdonald
2743 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
2745 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2747 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

2758 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
2759 * doc/autoconf.texi (Signed Overflow Examples): Give more
2760 discussion about the allow_superuser_privileges example,
2761 and change it a bit to make things clearer.
2762 (Optimization and Wraparound): Clarify whether the compiler
2763 will generate an infinite loop for the example derived from
2764 Autoconf's mktime test.
2765 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
2766 Also, clarify unsigned multiplication overflow.
2768 2007-01-04 Eric Blake <ebb9@byu.net>
2770 * bin/Makefile.am (RELEASE_YEAR): New macro.
2771 (edit): Use it to supply correct copyright year to scripts.
2772 * bin/autoconf.as (version): Use it.
2773 * bin/autoheader.in ($version): Likewise.
2774 * bin/autom4te.in ($version): Likewise.
2775 * bin/autoreconf.in ($version): Likewise.
2776 * bin/autoscan.in ($version): Likewise.

2780 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
2782 * doc/autoconf.texi (Integer Overflow): Revised based on today's
2783 feedback. The most important changes document what happens when
2784 you convert an out-of-range value to a signed integer type, and
2785 say that (sum < a) != (b < 0) reliably detects overflow when sum =
2788 * doc/autoconf.texi (Integer Overflow): Greatly expand and
2789 rewrite, taking notions from the recent discussion on the gcc and
2790 autoconf mailing lists; please see
2791 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
2792 and follow the many links.
2793 (Integer Overflow Basics, Signed Overflow Examples):
2794 (Optimization and Wraparound, Signed Overflow Advice):
2795 (Signed Integer Division): New sections.
2797 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
2799 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
2800 preprocessor macro arguments in traced name.
2801 * doc/autoconf.texi (Defining symbols): Document longstanding
2802 support for AC_DEFINE-ing macros with arguments, and document
2803 behavior when the same variable has multiple AC_DEFINEs.
2804 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
2805 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
2806 macros directly, giving much shorter and simpler code.
2808 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
2810 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
2811 space before "$ac_configure_args" to prevent a 'config.status
2812 --recheck' failure if ac_configure_args doesn't contain a leading
2813 space. This works around a problem with the XEmacs configure.ac,
2814 which uses the (undocumented) ac_configure_args variable
2815 inconsistently with Autoconf.
2817 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
2819 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
2820 Include <limits.h>, and use its INT_MAX to rewrite the
2821 j loop so that it does not overflow 'int'. Problem reported by
2823 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
2824 Play it safe by shifting left by 1 rather than multiplying by 2,
2825 as GCC is less likely to optimize this away when the value
2826 is signed (when it assumes overflow leads to undefined behavior).
2827 Also, don't assume time_t uses two's complement.
2829 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2831 * tests/torture.at (Substitute a 2000-byte string): Avoid using
2832 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
2833 dumps core on it. Report by Tim Rice.
2835 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2837 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
2838 --disable-option-checking to --help output even when
2839 AC_PRESERVE_HELP_ORDER is not used.
2840 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
2841 --with argument, rather than argument with [-.] replaced by
2843 * NEWS: Fix typo in previous change; the news was in the
2846 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2848 * NEWS: Warnings are now generated by default for unknown
2849 --enable-* and --with-* options.
2850 * doc/autoconf.texi (Option Checking): Renamed from
2851 (Configure Option Checking). Tighten up the wording a bit.
2852 (External Software, Package Options): Cross-reference to Option
2853 Checking, and use this to shorten our section.
2854 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
2855 "$x" to test "x$foo" != x.
2856 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
2857 Don't warn if $enable_option_checking is "no".
2858 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
2859 ac_unrecognized_opts to the empty string.
2860 Don't echo the unrecognized opts, as this might mishandle
2861 backslashes or leading -.
2862 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
2863 usage next to the other --disable-FEATURE options in the
2866 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2868 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
2869 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
2870 Print warning for unrecognized --with and --enable options
2871 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
2872 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
2873 Disable option checking when subdirs are configured.
2874 (AC_OUTPUT): If warnings are enabled, print warning about
2875 unrecognized --with and --enable options at the end of
2876 the configure output (as well as at the beginning).
2877 * doc/autoconf.texi (Option Checking): New node.
2878 Document new option warning functionality.
2880 2006-12-16 Eric Blake <ebb9@byu.net>
2882 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
2883 * NEWS: Start news for current version.
2885 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
2887 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2888 Define HAVE_GETMNTENT to 1, not to the empty string.
2889 Problem originally reported by Jochen Friedrich in
2890 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
2892 This change prompted by a problem report by Andrey Simonenko in
2893 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
2894 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
2895 object-like macros only, in the traditional portable character
2897 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
2898 Warn about attempts to define things that are not identifiers.
2899 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
2900 awful hack that AC_DEFINEd macro names containing parentheses.
2902 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
2904 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
2905 too drastic, even if Texinfo in theory requires it for info mode.
2907 (config.status Invocation): Renamed back from Recreating a
2909 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
2910 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
2912 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2914 * NEWS: Version 2.61a.
2916 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2917 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2919 * NEWS: Document changes with echo and printf, and the lack
2920 of limits on the total size of multi-line values of substituted
2921 variables, and the AC_FUNC_FSEEKO fix.
2923 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
2925 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
2926 Writing configure.ac.
2927 (Autoconf Input Layout): Renamed from configure.ac Layout.
2928 (Recreating a Configuration): Renamed from config.status Invocation.
2929 (Obsolete Recreation): Renamed from Obsolete config.status Use.
2930 (acconfig Header): Renamed from acconfig.h.
2931 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
2932 (Writing Testsuites): Renamed from Writing testsuite.at.
2933 (Autom4te Cache): Renamed from autom4te.cache.
2935 * BUGS: Remove mention of VPATH problem, since it's now documented
2936 not to be a bug in the Autoconf build procedure itself, but rather
2937 a problem with the proprietary `make' programs.
2939 * doc/autoconf.texi (Build Directories): Add a cross reference
2942 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
2943 * doc/standards.texi: Sync from gnulib.
2945 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
2946 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
2947 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
2948 generated automatically.
2950 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
2952 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
2953 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
2954 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
2956 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2958 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
2959 `CEOF$ac_eof' special marker, the awk script cannot contain a
2960 line matching `^CEOF', so this is not needed any more.
2961 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
2962 special marker in the test.
2964 2006-12-06 Stepan Kasal <kasal@ucw.cz>
2966 * tests/tools.at (autom4te preselections): Use `find -newer';
2967 remove one of the sleeps.
2969 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
2970 more readable, using ...
2971 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
2973 * doc/autoconf.texi (autoheader Invocation): Do not double-
2974 quote the parameter of `AH_BOTTOM' in the example.
2976 2006-12-05 Stepan Kasal <kasal@ucw.cz>
2978 * doc/autoconf.texi (Configuration Headers): Remove the
2979 example with multiple input files.
2980 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
2981 multiple input files.
2983 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2985 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
2986 creating the awk substitution script, handle one input line at a
2987 time, so that the maximum length of a substituted (multi-line)
2988 value is not limited by the size of the sed pattern space.
2989 The trade-off is a slightly repetitive sed script.
2990 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
2991 can only have up to 7 characters, due to Solaris 10 /bin/sed.
2992 * tests/torture.at (Substitute a 2000-byte string): Increase the
2993 test with several long lines, they should not be caught by sed
2996 * tests/tools.at (autom4te preselections): New test, to flag
2997 entries missing from autom4te.cfg.
2998 Report by David Byron <dbyron@hheld.com>.
3000 * tests/torture.at (Substitute a 2000-byte string): Actually use
3001 AC_PROG_AWK, so the last change works as intended.
3002 (Substitute and define special characters): Likewise.
3003 (Substitute a newline): Likewise.
3005 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3006 instead of `awk' consistently.
3007 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3008 * tests/torture.at (Torturing config.status): Test both the
3009 result of AC_PROG_AWK and plain awk.
3010 (Substitute a 2000-byte string): Likewise.
3011 (Substitute and define special characters): Likewise.
3012 (Substitute a newline): Likewise.
3014 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3016 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3017 can be assigned to a function pointer. Problem reported by
3018 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3019 part of a patch by Ralf Wildenhues in that same bug report.
3021 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3023 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3024 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3026 2006-12-01 Eric Blake <ebb9@byu.net>
3028 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3029 cross-compiling from cygwin to mingw.
3030 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3031 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3032 to lib/autoconf/c.m4.
3034 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3036 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3037 string for more reliable failure. Wrap the entire test that
3038 causes the broken Solaris printf to dump core, in a subshell,
3039 so the segmentation fault message is reliably suppressed.
3040 Fix shell expansion errors by using /usr/ucb/echo always;
3041 avoid an error on systems without it by another subshell.
3042 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3043 subshell-$as_echo to `as_echo', for better error message.
3045 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3047 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3048 `BASH_SOURCE' contain a newline, set them to empty, as they may
3051 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3053 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3054 years and is too hard to maintain now. The last straw was
3055 reported by Jerker Baeck in
3056 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3057 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3058 * doc/autoconf.texi (Particular Functions): Move
3059 AC_FUNC_SETVBUF_REVERSED from here...
3060 (Obsolete Macros): ... to here. Say that it does nothing now.
3061 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3062 Turn into (almost) a no-op.
3064 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3066 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3067 These macros are obsolescent and new applications shouldn't need them.
3068 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3069 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3070 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3071 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3072 (AC_FUNC_VPRINTF): Likewise.
3073 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3074 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3075 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3077 * doc/autoconf.texi (Setting Output Variables): Mention that
3078 @VAR1@VAR2 has unspecified behavior. Problem reported by
3080 * NEWS: Mention this.
3082 * Makefile.am: Put only a single '#' into the copyright notice,
3083 so that it's also present in the output file. Standardize wording
3084 in makefile copyright notices to match GNU coding standards.
3085 * bin/Makefile.am: Likewise.
3086 * doc/Makefile.am: Likewise.
3087 * lib/Makefile.am: Likewise.
3088 * lib/freeze.mk: Likewise.
3089 * lib/autoconf/Makefile.am: Likewise.
3090 * lib/autoscan/Makefile.am: Likewise.
3091 * lib/autotest/Makefile.am: Likewise.
3092 * lib/m4sugar/Makefile.am: Likewise.
3093 * man/Makefile.am: Likewise.
3094 * tests/Makefile.am: Likewise.
3095 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
3098 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3100 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3101 in the sed script that mangles the awk script: delete up to the
3102 first exclamation mark only.
3103 * tests/torture.at (Substitute and define special characters):
3106 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3108 Rewrite config files generation: avoid quadratic growth in
3109 the number of substituted variables by using awk instead of sed
3110 for the bulk of the substitutions.
3111 * NEWS: Mention this.
3112 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3113 forbidden in the output (and thus input) file.
3114 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3115 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3116 generate just one large awk script for substitutions,
3117 eliminating much of the earlier complexity, while adding some
3118 new complexity. Only expand the substitution templates at
3119 configure time, for smaller configure script size. If
3120 _AC_SUBST_FILES are used, test 'awk' for working getline support
3121 at config.status time. If absent, interpolate through the
3122 shell. The awk script was written with much help
3123 from Paolo Bonzini and Paul Eggert.
3124 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3125 (_AC_SED_FRAG_NUM): Likewise.
3126 (_AC_SUBST_CMDS): Renamed from...
3127 (_AC_SED_CMDS): ...this.
3128 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3129 * tests/torture.at (Substitute a 2000-byte string): Also
3130 substitute a line with 1000 words, and a variable with several
3132 (Substitute and define special characters): Test awk special
3133 characters, and put substitution input strings `@foo@' in the
3134 output, to test that no recursion happens; test several other
3135 combinations from Paolo Bonzini.
3137 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3139 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3140 that replaced echo with AS_ECHO where this wasn't necessary.
3141 Problem reportd by Ralf Wildenhues.
3142 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3143 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3144 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3146 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3148 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3150 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3152 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3153 that traditional Awk lacks 3-arg "split". It has it.
3154 Mention that FS must be a single character, and a few other
3155 99-byte limits of traditional Awk.
3156 Mention that if (i in a) doesn't work with traditional Awk.
3158 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3160 * tests/autotest.at (BSx641-newline in command):
3161 (BS-BS-newline in command, BSx640-newline in command):
3162 (Newline-CODE-BS-newline in command):
3163 (Single-quote-BS-newline in command):
3164 (Single-quote-newline-BS-newline in command):
3165 Use printf '%s\n' instead of echo, for portability to hosts
3166 where echo interprets backslashes. This will break on hosts
3167 that lack printf, but for now let's assume all such hosts
3168 are dead (if not, we should get reports of test failures).
3170 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3172 'echo' has some portability problems, when given a first argument
3173 with a leading '-', or when given any argument containing '\'.
3174 Avoid using 'echo' in these cases.
3175 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
3176 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
3177 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3178 * lib/autotest/general.m4 (AT_INIT): Likewise.
3179 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
3180 argument might be unportable.
3181 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
3182 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
3183 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
3184 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
3185 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
3186 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
3187 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
3188 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
3189 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
3190 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
3191 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
3192 (AC_PROG_MAKE_SET): Likewise.
3193 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
3194 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
3195 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
3196 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
3197 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
3198 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
3199 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3200 * bin/autoconf.as: Redo verbose flag implementation, as the old
3201 scheme wouldn't work with AS_ECHO.
3202 * lib/autotest/general.m4 (AT_INIT): Likewise.
3203 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3204 Don't use ECHO_T, since ECHO_N is now reliable.
3205 * lib/autotest/general.m4 (AT_INIT): Likewise.
3206 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3207 rather than using a here-document to put the script into a file.
3208 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3210 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3211 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3212 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3213 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3214 * lib/autotest/general.m4 (AT_SETUP): Likewise.
3215 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
3216 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3217 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3218 operand, as AS_ECHO requires. Avoid double file name expansion.
3219 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3220 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3221 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3222 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3223 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3224 Double-quote strings that would otherwise contain M4 comments.
3225 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3227 * configure.ac (AC_INIT): Bump to 2.61a.
3230 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3234 * configure.ac (AC_INIT): Bump to 2.61.
3237 * tests/autotest.at (Macro with backslash in a test title):
3238 Comment out for now, as this tests neither fails nor passes
3239 reliably. Problem reported by Ralf Wildenhues.
3241 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3243 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
3244 in previous change, which caused test failures.
3246 2006-11-16 Stepan Kasal <kasal@ucw.cz>
3248 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
3249 code for --enable, --disable, --with, and --without to...
3250 (_AC_INIT_PARSE_ENABLE): ... a new macro.
3251 * doc/autoconf.texi (Package Options):
3252 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
3254 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3256 Import these changes from config via gnulib:
3258 2006-11-15 Ben Elliston <bje@gnu.org>
3260 From Josselin Mouette <joss@debian.org>:

3313 first argument may also contain dots.
3315 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
3317 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
3318 benefit of platforms like Solaris+GCC where it is common to have a
3319 non-working g++ installation.
3321 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3322 and Joel E. Denny <jdenny@ces.clemson.edu>

3326 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
3329 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3331 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
3332 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
3333 Imported from a similar patch to gnulib by Bruno Haible.
3335 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3337 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
3338 * doc/autoconf.texi (C Compiler): Document them.
3339 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
3340 New macros, taken from gnulib.

3348 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3350 * tests/torture.at (Configuring subdirectories): Do not skip
3351 Automake 1.10 nor future Automake 11.1 (sic).
3353 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
3354 and Stepan Kasal <kasal@ucw.cz>
3356 Handle special characters in test case titles correctly.
3357 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
3359 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
3360 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
3361 argument. Extend to check titles printed by ./micro-suite and
3362 ./micro-suite -l and the title in micro-suite.log.
3363 (Backquote in a test title,
3364 Single-quote in a test title,
3365 Double-quote in a test title): Don't expect failure anymore.
3366 (Backslash in a test title): Put a non-whitespace character after the
3367 backslash so that Bourne shells might actually see it as an escape
3369 (Brackets in a test title,
3370 Pound in a test title,
3371 Comma in a test title,
3372 Quoted Macro in a test title,
3373 Macro in a test title,
3374 Macro with single-quote in a test title): New tests.
3375 (Macro with backquote in a test title,
3376 Macro with double-quote in a test title,
3377 Macro with backslash in a test title): New tests expected to fail.
3378 * tests/torture.at (#define header templates): M4-quote this title in
3379 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3380 The visible effect was a stray [] in the testsuite output.
3382 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3384 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3385 `trap ... 0' inside a function, for AIX sh.
3387 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3389 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3390 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3391 5363) simply issues a warning when dividing by zero at compile
3392 time. Problem reported by Elias Pipping.
3394 2006-10-26 Eric Blake <ebb9@byu.net>
3397 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3398 show effect on macros that expand with commas.
3399 Reported by Joel E. Denny.
3401 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
3402 Also work with M4 1.4.8.

3412 `--force' always rewrites the output file.
3414 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
3416 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm
3417 needs operands on NetBSD 2.0.2. Problem reported by Bruno Haible.
3419 2006-10-24 Stepan Kasal <kasal@ucw.cz>
3421 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
3423 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
3425 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3426 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3427 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3428 reported by Nelson H. F. Beebe for Coreutils 6.4.
3430 * tests/tools.at (autoconf --trace: user macros): Remove test
3431 for tracing multiline macros, since m4 1.4.7a uses a different
3432 way to number lines. Problem reported by Ralf Wildenhues.
3434 2006-10-24 Stepan Kasal <kasal@ucw.cz>
3436 * bin/autom4te.in (handle_m4): Do not redirect stdin to
3437 /dev/null since the heuristics for interactive behaviour was
3440 * bin/autom4te.in: With --force, always refresh the output
3441 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
3443 * bin/autoconf.as: Fix the verbose message at the end.
3445 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

3455 2006-10-15 Karl Berry <karl@gnu.org>
3456 * build-aux/texinfo.tex: automake 1.10
3458 * NEWS: Remove AC_CACHE_CHECK_INT.
3459 * doc/autoconf.texi (Caching Results): Likewise.

3510 (Imported from Automake.)
3511 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3512 which incorrectly sets the mode of an existing destination
3513 directory. In some cases the unpatched install-sh could do the
3514 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3515 system. We hope this is rare in practice, but it's clearly worth
3516 fixing. Problem reported by Alex Unleashed in
3517 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3518 Also, don't bother to check for -m bugs unless we're using -m;
3519 suggested by Stepan Kasal.

3573 include the default headers, and redefine obstack_chunk_alloc
3574 and obstack_chunk_free. Fixes false failure with glibc.

3596 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
3597 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
3598 Use a better substitute, by inspecting the output of "ls"
3599 rather than just using ":".
3600 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
3601 rather than AS_EXECUTABLE_P, since we needn't worry about
3602 non-regular files here.
3604 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
3605 due to configuration hassles with this. See Tonya Underwood's report

3618 initialization which is not inherited through the environment
3619 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
3620 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

3629 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
3630 comment about ac_cpp_err; it was incorrect, and anyway
3631 ac_cpp_err is being removed below.
3632 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
3633 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
3634 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
3636 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
3637 with werror_flag and conftest.err and so forth. This is more
3638 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
3639 and anyway the user shouldn't normally want to see this gorp logged.
3640 Problem reported by Ralf Wildenhues.
3641 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
3642 empty, not 'no', since the rest of the code uses 'test -z'.

3646 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):

3650 Problem reported by mwoehlke in
3651 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
3653 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
3654 than creating a file to use with test -x; this is much faster.
3656 2006-10-02 Bruno Haible <bruno@clisp.org>
3658 * lib/autom4te.in (Automake-preselections): Add
3659 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.

3668 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
3669 fseeko testing program twice; just use the earlier result.
3670 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3671 Set cache var to 'unknown' (not 'no') if leaving the macro unset
3672 still doesn't let the program compile.
3673 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
3676 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
3677 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
3678 include it, without including anything else.
3679 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
3681 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

3686 `error.h', and include it, for a `error_at_line' prototype.
3687 Use a nonempty format string in the link test.
3688 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
3689 for a declaration of wait3.

3695 can apply to constants too, and that it checks for macro defns.
3696 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

3698 values. Problem reported by Ralf Wildenhues.

3913 broken lex libraries like native ia64-hp-hpux11.22; see
3914 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

4042 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
4043 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
4044 -Wundef -Werror". Problem reported by David Fang in
4045 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

4068 problems with arg script text that doesn't end in newline, and

4071 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
4073 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

4092 the compiler created a file "b.out" when it didn't create anything
4094 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):

4105 less skeptical about "volatile", after discussion with
4106 Bruno Haible on bug-gnulib.
4107 (Limitations of Usual Tools): Warn about sed stripping
4108 leading white space from text. From Bruno Haible.
4110 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4112 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
4113 compiler complains about it, even if things works after the
4114 complaint. Problem reported by Peter O'Gorman.
4116 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
4117 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
4118 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
4120 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
4122 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
4123 after -R regardless of host. Patrick Welche reports that this
4124 fixes things on NetBSD 3.99.

4134 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
4135 under AC_C_VOLATILE.
4136 (Volatile Objects): Be a little less skeptical about what
4137 "volatile" means. Derived from thoughts by Ben Pfaff in
4138 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
4140 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4142 * doc/autoconf.texi: Fix some typos.
4144 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4146 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4147 more globally, since the 2006-06-30 patch didn't suffice. Problem
4148 reported by Keith Marshall. Also, don't bother with builddir2,
4149 since it shouldn't be needed any more.
4151 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
4153 * doc/autoconf.texi (Generic compiler characteristics):
4154 Document AC_COMPUTE_INT. Fix wrong statements on Default

4168 * NEWS: Document previous change.
4170 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4172 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4173 Require that long long int be at least 64 bits wide. C99 requires
4174 this and enough programs depend on it so we should check for it.
4175 Bruno Haible reports in
4176 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4177 that long long int is 32 bits wide with some nonstandard compilers.
4178 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
4180 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4182 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4183 to a nonexistent file, so that we don't have to worry about
4184 a local site configuration that doesn't use /usr/local.
4185 Problem reported by Keith Marshall in
4186 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4188 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4190 * doc/autoconf.texi: Be more consistent about using @acronym with
4191 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4192 quite right (it talked about "OSF/Tru64", even though the
4193 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4194 and it even mentioned "OSF 4"!) and at this point there's little
4195 reason to talk about OSF any more, since it died in 1994.
4196 (Specific Compiler Characteristics): Simplify example of
4197 negative-size array.
4198 (File Descriptors): Reorder to make the text flow better.
4199 Remove joke about "appreciate the various levels"; I didn't get it.
4200 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4201 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4202 (File Descriptors, Limitations of Usual Tools):
4203 Tone down the advice against renaming or removing open files.
4204 (Limitations of Usual Tools): Add a new section, on 'rm'.
4206 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4208 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4209 -lXt in LIBS, idea from Karsten Hopp; this was due since
4212 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4213 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4214 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4215 (which belong to Xt, not X itself). See Debian bug 327655.
4217 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4219 * configure.ac (AC_INIT): Bump to 2.60a.
4222 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4226 * configure.ac, NEWS: Update.
4228 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4230 * config/texinfo.tex: Sync from upstream.
4232 * bin/autom4te.in (handle_traces): Transform the `@S|@'
4233 quadrigraph correctly in traces.
4235 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
4238 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
4239 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4241 * doc/autoconf.texi (Changed Directory Variables): New node,
4242 to document the whole `datarootdir' business a bit better.
4244 * tests/torture.at (datarootdir workaround): Extend test.
4245 Prompted by report by Alexandre Julliard.
4247 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4249 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4250 when using default mode of IBM C 6 for AIX. Problem and two-line
4251 fix reported by Larry Jones.
4253 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4255 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4256 about literal '${datarootdir}' if a definition is found in the
4259 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4261 * NEWS: Use "M4" rather than "m4" when appropriate.
4262 Problem reported by Eric Blake.
4263 * doc/autoconf.texi: Likewise.
4264 Use @acronym around BSD, GCC, and GNU when appropriate.
4265 (Why GNU M4): Renamed from "Why GNU m4".
4266 (Redefined M4 Macros): Mention that Posix
4267 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4268 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4271 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4273 * bin/autom4te.in (handle_output): Do not forbid the empty
4275 * tests/tools.at (autoconf: the empty token): New test.
4277 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4279 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4280 calls, so that we do not care whether they are LIFO or FIFO;
4281 in the m4_wrap, do not check which diversion is the topmost
4282 one, just check that the stack is balanced at the end.
4283 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4284 base diversion forever--pop the previous diversion before
4285 opening the new one; consequently, remove the m4_wrap call.
4286 * lib/autotest/general.m4 (AT_INIT): Likewise.
4287 * tests/m4sugar.at: Do not use
4288 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

4291 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4293 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4294 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4295 Rework example of m4wrap token-pasting trouble so that it doesn't
4296 care whether it's LIFO or FIFO.
4297 Fix some "contrary to"s that are awkward in English.
4299 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4301 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4302 to `yes' instead of `int$1_t' if the type is found, for more
4303 consistent configure output (where $1 is the number of bits).
4304 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4305 Suggested by Bruno Haible.
4307 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4308 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4309 with system headers. Report by Bruno Haible.
4311 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4313 * config/config.guess, config/config.sub: Sync from upstream.
4315 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4316 in order to avoid picking up an older installed frozen m4sh.m4f.
4317 Besides an outdated shell startup, this could have been created
4318 by an earlier M4 version with incompatible frozen file format.
4320 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4322 * README: Recommend m4 1.4.4 instead of 1.4.3..
4323 * doc/autoconf.texi: Likewise.
4324 (Special Chars in Names): Say that $(.FOO) is portable, as
4325 suggested by Stepan Kasal.
4326 (Installation Directory Variables, Build Directories):
4327 (Automatic Remaking, Subdirectories, Fortran Compiler):
4328 (Making testsuite Scripts, Defining Directories):
4329 Quote variable usages better.
4330 (Making testsuite Scripts): Add clean-local rule to makefile
4331 snippet, by Eric Blake.
4332 (Installation Directory Variables): Fix table item font.
4333 Reword slightly to clarify. Generalize advice about
4334 not using special characters to include all file-related
4335 vars, not just VPATH.
4336 (Special Chars in Variables): Warn about special characters in
4338 (Assignments): Clarify default-value example as suggested by
4340 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4341 (Special Shell Variables): Note leading ./ or ../, as suggested
4343 (Limitations of Builtins): Under cd, warn about CDPATH.
4344 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4347 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4349 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4350 `@var', for texi2html.
4351 (Systemology): Some more word wrapping, for DVI output.
4352 (autom4te Invocation): The short option for `--melt' is `-M',
4355 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4357 * doc/autoconf.texi: More formatting and English tweaks,
4358 many suggested by Ralf Wildenhues.
4359 Reword to avoid "@code{...}'s" and the like, since it's ugly
4360 with Emacs info mode. discontents -> woes.
4361 Put a few "will"s back. time stamp -> timestamp.
4362 side-effect -> side effect.
4364 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4366 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4367 Warn about $@ not persisting. Problem reported by Julien Danjou in
4368 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4369 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4370 Mention other special chars, too.
4372 2006-06-14 Eric Blake <ebb9@byu.net>
4374 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4376 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4378 * doc/autoconf.texi: Some systematic minor improvements, as
4379 follows. Use "makefile" when talking about makefiles
4380 generally (which might be named "makefile" or "Makefile" or even
4381 "foo.mk"), "Makefile" when talking about a specific makefile
4382 called "Makefile". This unclutters the text from weird quotes
4383 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4384 values" rather than "@var{foo}s" and similar constructs containing
4385 "}s". Use "Make rules" rather than "Makefile rules". Minor
4386 English-language improvements. Change the prefix "sub-" to "sub"
4388 Put blank lines around examples more consistently.
4389 Avoid "rather" and "very" as intensifiers.
4390 Avoid "will" as an auxiliary.
4391 (Limitations of Make): Split this node into....
4392 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4393 (Leading _ in Macro Names, Backslash-Newline-Newline):
4394 (Backslash-Newline Comments, Long Lines in Makefiles):
4395 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4396 (obj/ and Make, make -k Status, VPATH and Make):
4397 (VPATH and Double-colon, $< in Explicit Rules):
4398 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4399 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4400 New nodes, resulting from splitup of Limitations of Make.
4401 All cross-references changed. Raise the top node from
4402 a section to a chapter, and all subnodes accordingly.
4403 Redo the introductory wording to match the new organization.
4404 (Installation Directory Variables): Use an example that is
4405 closer to what Autoconf actually does. Mention that VPATH's
4406 value should not contain metacharacters or white space.
4407 (Fortran Compiler): Fix a VPATH bug in an example.
4408 (Leading _ in Macro Names): Mention that this problem is no longer
4409 of practical concern.
4410 (VPATH and Make): Reword the advice to make it clearer
4411 that Autoconf and Automake support VPATH in non-GNU make, but
4412 many packages have bugs in this area.
4413 ($< in Explicit Rules): Refer to Build Directories rather
4414 than using a (non-VPATH-safe) example.
4415 (Automatic Rule Rewriting): Mention the sort of disaster that
4416 can ensue with Solaris-style rule rewriting with VPATH.
4418 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4420 * doc/install.texi (Compilers and Options): Weaken the
4421 suggestion to use GNU make for VPATH builds.
4423 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4424 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4426 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4427 in regular expression.

4431 * doc/autoconf.texi (Installation Directory Variables):
4432 Drop extra @samp from `@table @samp' item.
4433 (Limitations of Usual Tools): Comment fix.
4434 Do not nest @samp just to point to other table items.
4435 (Writing testsuite.at) <AT_CHECK>: The second argument to
4436 `@dvar' is already @samp'ed.
4437 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4438 do not use @var in the second argument.
4440 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4442 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4443 $as_shell.exe too. Problem reported by Andreas Buening in
4444 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4446 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4448 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4449 `unused variable' compiler warning, for `-Wall -Werror'.
4450 Reported by Jaap Haitsma in
4451 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4453 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4455 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4456 case the compiler dumps core. Problem reported for
4457 OpenServer 5.0.7 by Tim Rice in
4458 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

4462 2006-06-06 Tim Rice <tim@multitalents.net>.
4464 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4465 "ERROR" only shows up in "make check" output if there is an

4489 * config/texinfo.tex: Sync from upstream.
4491 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4492 seen, invoke libtoolize with `--ltdl' argument.
4493 * lib/autom4te.in (Autoreconf-preselections): Adjust.
4495 Suggested by Eric Blake.
4497 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

4516 * tests/base.at: Check AC_REQUIRE's error message.
4517 * tests/local.at (AT_CHECK_M4): New macro, almost identical
4519 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
4521 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
4522 `expout' as the last parameter.
4523 * tests/tools.at: Adapt to the above change.
4525 2006-06-04 Stepan Kasal <kasal@ucw.cz>
4527 * doc/autoconf.texi (Limitations of Usual Tools): Correct
4528 information about race-free implementations of mkdir.

4537 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
4539 * NEWS: GNU make now recommended for VPATH builds.
4540 Mention that some macros are now documented to be obsolescent.
4541 * doc/autoconf.texi:
4542 Prefer "current" to "modern" to describe
4543 currently-used (albeit perhaps old-fashioned) hosts.
4544 Mention which ancient features no longer need to be worried about.
4545 setgid -> set-group-ID
4546 setuid -> set-user-ID (these are the Posix terms)
4547 Fix some misuses of "only".

4562 Omit longwinded and obsolescent discussion of cp -f.
4563 Modernize discussion of expr, ls.
4564 (Limitations of Make): Modernize discussion of VPATH builds.
4565 Mention $? as a workaround in some cases.
4566 * doc/install.texi (Basic Installation):
4567 Mention "./configure; make; make install" first. Be more
4568 specific about why this file is generic. Remove unnecessary
4569 parens. Remove misleading "only". Remove obsolete advice
4570 about csh. Don't say "configure" takes awhile; say it
4571 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
4572 and CC=c99 rather than CC=c89, as these are blessed by current
4573 Posix. Recommend GNU make if doing a VPATH build.
4575 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
4577 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
4578 examples involving shell prompts.

4581 and Paul Eggert <eggert@cs.ucla.edu>
4583 * doc/autoconf.texi (Here-Documents): Add details about the
4584 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
4585 use "here-documents" instead of "here documents".
4587 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4596 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
4598 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
4599 about quoting the case statement, just in case.
4600 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
4601 was fixed in ksh93g; reported by Ralf Wildenhues.

4615 argument with leading hyphen. Problem reported by Paul Eggert.
4617 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4619 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
4620 about quoting ac_try: quote all of it, if any of it seems suspicious.
4621 This means we don't have to worry about ${ or sed any more.
4622 Also, double-quote the case statement, to work around misuses via
4623 underquoting as reported by Ralf Wildenhues in
4624 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
4625 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
4626 undocumented and dangerous macro.

4640 Problem reported by Ralf Wildenhues in
4641 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
4642 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
4643 pre-2006-05-26 definitions, but leave in the comments that
4644 these macros are dangerous and should not be used.
4645 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
4646 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
4647 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
4648 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.

4651 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4653 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
4654 the use of 'tr', since this is our only use of 'tr'.
4656 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4657 and Paul Eggert <eggert@cs.ucla.edu>
4659 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

4662 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4664 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
4665 the output file in the `${datarootdir}' test.
4667 2005-05-28 Stepan Kasal <kasal@ucw.cz>
4668 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4670 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
4671 mention of `datarootdir' in the input file(s), but literal
4672 `${datarootdir}' in the output file, and we haven't warned yet,
4673 then warn as well: the user may have (erroneously) used
4674 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
4675 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
4676 * tests/torture.at (datarootdir workaround): Extend this test.

4680 and Paul Eggert <eggert@cs.ucla.edu>
4682 * doc/autoconf.texi (autoheader Invocation): The first argument to
4683 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
4684 alternatives and clear up the language a bit.
4686 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
4688 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
4689 ac_config_guess, ac_config_sub, ac_configure.
4690 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4691 Fix typo that prevented an unnecessary space from being removed.
4692 Problems reported by Ralf Wildenhues in:
4693 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
4695 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4697 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
4698 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
4699 Don't use the term "thread-safe" to talk about mkdir race
4700 conditions, since the problem is more a process than a thread
4701 issue. Problem reported by Stepan Kasal in:
4702 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
4703 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
4704 the test for 'install' more closely. Look at MKDIR_P first.
4705 Look in the PATH, and at /opt/sfw/bin.
4706 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
4707 Don't bother to try mkdir -p, since we already check mkdir --version;
4708 just look at the version number. (There's no easy way to check
4709 for race-free implementations.)
4710 * tests/tools.at (autoconf: subdirectories): Adjust to above
4711 changes, since MKDIR_P now might end in "/mkdir -p".
4713 * doc/autoconf.texi (autoheader Invocation): Mention that the
4714 first arg of AC_DEFINE_UNQUOTED must be a literal.
4715 Problem reported by Ben Pfaff in
4716 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
4718 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
4719 * doc/autoconf.texi (Special Chars in Variables): New section.
4720 (Preset Output Variables): Warn about special chars in CPPFLAGS.
4721 (Installation Directory Variables): Quote $(datadir) better.
4722 (Limitations of Builtins): Describe some of eval's trickiness.
4724 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
4725 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
4726 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
4727 in front of every arg, not just trailing args. Quote apostrophes.
4728 (_AC_EVAL_ECHO): New macro.
4729 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
4730 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
4732 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
4733 exposed by quoting of eval argument. Put the command on line line
4735 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
4736 (_AC_PATH_X, AC_PATH_X): Quote more safely.
4737 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
4738 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
4739 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
4740 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
4741 Use eval more safely.
4742 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
4743 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
4745 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
4746 lines, exposed by quoting of eval argument.
4748 2006-05-26 Stepan Kasal <kasal@ucw.cz>
4749 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4751 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
4752 initialization of `ac_cv_exeext', do not override it if it was
4753 already set, unless it was set to `no', for compatibility with
4754 Autoconf-2.13, and comment this.
4755 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
4756 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
4757 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
4758 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
4759 Document that this test may be overridden by setting
4762 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4764 Revert these two patches:
4766 2006-04-06 Eric Blake <ebb9@byu.net>
4767 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4768 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4771 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4772 Clean up _AC_COMPILER_EXEEXT* macros.
4773 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4774 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4775 ac_file to the name of the default output file and call
4776 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4777 initial `rm' of the candidate files...
4778 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4779 the same list in subsequent `rm' calls, and for the temporary
4780 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4781 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4782 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4783 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4784 no longer needed) by libtool. Make it a cache check.
4785 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4786 copied here by mistake.
4787 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4788 _AC_COMPILER_EXEEXT.
4789 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
4790 _AC_COMPILER_OBJEXT directly.
4791 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4793 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4795 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
4796 Fix description of how the buggy `sed' works.
4798 2006-05-25 Noah Misch <noah@cs.caltech.edu>
4802 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
4803 ENOLCK. Only mention `make -j' when applicable. Only raise
4804 fatal errors when `make -j' is involved. Improve error message.
4806 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4808 * doc/autoconf.texi (Here-Documents): We now know more about
4809 the variable expansion in here documents bug.
4810 Thanks to Tim Rice and Stepan Kasal.
4812 * doc/autoconf.texi (Making testsuite Scripts): Add an example
4813 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
4815 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4817 * tests/autotest.at (Multiline command from M4 expansion):
4818 No failure to be expected if the shell quotes newlines in
4819 commands in the `set -x' output. Report by Tim Rice.
4822 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4824 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
4825 expansion in the here-documents used by config.status, as that
4826 runs afoul of the Korn shell version M-12/28/93d bug described in
4827 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
4828 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
4829 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
4831 2006-05-23 Jim Meyering <jim@meyering.net>
4833 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
4834 Fix typo introduced with 2006-04-02 change. It reversed the sense
4837 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4839 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
4840 ac_dB slightly, to save bytes in the script.
4841 Max out at 50 lines, rather than 96; this is more likely
4842 (though not guaranteed) to avoid obscure 'sed' failures.
4844 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4846 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
4847 `tr -d -' as bad option argument. Work around this by deleting
4848 an unrelated character.
4849 Report by Tim Rice <tim@multitalents.net>.
4851 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
4852 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4853 Stepan Kasal <kasal@ucw.cz>
4855 * doc/autoconf.texi (Particular Programs): Do not promise that
4856 we always prefer the GNU version of the program, and that we
4857 search according to PATH; both rules can have exceptions.
4858 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
4859 AC_PROG_SED. Move descriptions of limitations
4860 to the Limitations of Usual Tools section.
4861 (Limitations of Usual Tools) <sed>: Mention script length
4862 limitations with Solaris /usr/ucb/sed.
4863 <grep>: Fix wording for empty alternative. Mention that -c and
4864 -l should not be combined, and that -E and -F should not be
4867 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4868 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4870 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
4871 limits in Solaris 8 /usr/ucb/sed by testing a long script.
4873 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4875 * doc/autoconf.texi (Defining Symbols): Literal parameter of
4876 AC_DEFINE is now passed to m4_pattern_allow.
4877 * NEWS: Mention that; likewise for AC_SUBST.
4878 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
4879 the parameter to m4_pattern_allow.
4880 * tests/tools.at: Add a check for that.
4882 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4884 * lib/autoconf/status.m4: Fix typos.
4886 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4888 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
4889 only the files that this macro generates.
4891 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4893 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
4894 the HP-UX sed limitation of 99 commands, labels do not count.
4895 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
4897 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
4899 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4901 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4902 Import the following fix from coreutils:
4904 2006-01-13 Jim Meyering <jim@meyering.net>
4906 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
4907 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
4908 not double-quote uses of that variable, to accommodate the rare
4909 case in which getmntent is available in none of the libraries
4910 checked. This happens at least on FreeBSD 5.0.
4912 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
4914 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
4915 ac_config_guess, ac_config_sub, and ac_configure, since evidently
4916 some other programs unwisely rely on these undocumented vars.
4917 But put in warning comments about them.
4918 Problem reported by Ralf Wildenhues in
4919 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
4920 * NEWS: Document that these variables are intended to go away.
4922 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4924 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
4925 and set the language to C++ (analogous to the equivalent Fortran
4928 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
4929 * doc/autoconf.texi (C++ Compiler): Document it.
4930 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
4933 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
4935 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
4936 that caused config.status to generate 100-command sed scripts; the
4937 portable limit is 99.
4939 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4941 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
4942 variable `ac_d' instead of `d' to avoid infringing namespace.
4943 Report by Ralf Menzel.
4945 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
4947 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
4948 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
4949 * tests/tools.at (autoconf: subdirectories): New test, taken from
4950 the corresponding problem report by Ralf Wildenhues in:
4951 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
4953 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
4954 Quote some uses of shell variables if they might suffer unexpected
4955 globbing. This doesn't fix all instances of quoting problems that
4956 I found, just the easy ones that look safe.
4957 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
4958 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
4959 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
4960 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
4961 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
4962 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
4963 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
4965 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
4966 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
4968 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4970 * bin/autoreconf.in ($help): Reword according to the manual.
4971 Suggested by Olly Betts.
4973 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
4974 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4976 * bin/autoreconf.in: Pass the directory argument to
4977 `require_configure_ac'. Fix comment.
4978 * tests/torture.at (Configuring subdirectories): Expose this.
4979 Reported by Olly Betts.
4981 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4983 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
4984 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
4985 Automake as follows:
4987 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
4988 `$configure_in' instead of `configure.in', to preserve
4989 directory component.
4991 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4993 * config/config.guess, config/config.sub, config/texinfo.tex,
4994 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
4996 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
4998 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
4999 test for C99 conformance; (bool) 0.5 is an integer constant
5000 expression, but (bool) -0.5 is not. Problem reported by Fedor
5001 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5003 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5005 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5006 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5007 Warn about obsolete install-sh files. Remove stray sentence
5008 fragment and fix cross reference.
5009 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5010 install -d; this undoes the 2006-05-10 change.
5011 (MKDIR_P): Mark with AN_MAKEVAR.
5012 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5013 that we don't require $INSTALL to be thread-safe. Move comments
5014 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5015 of AC_PROG_INSTALL. Output a message saying that we're checking
5016 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5017 MKDIR_P instead of AC_SUBST.
5018 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5019 Special magic for MKDIR_P, too.
5020 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5022 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5024 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5026 Sync from Automake, as follows:
5028 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5029 * config/install-sh: Initialize IFS, so field splitting isn't
5031 * config/mkinstalldirs: Likewise.
5032 * config/missing: Remove superfluous quotes. Replace all uses of
5033 `[' by `test', for consistency, and for..
5034 * config/missing (sed_minuso, sed_output): New variables.
5035 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5036 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5037 Fixes `missing' to detect `--output' for help2man. Fixes
5038 PR automake/483. Report by Dennis J. Linse.
5039 (autom4te): Document in `missing --help'.
5041 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5043 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5044 * config/install-sh: Don't use 'path' to talk about file names,
5045 as per GNU coding standards. Close a race condition reported by Ralf
5046 Wildenhues and Stepan Kasal. There is still a race condition
5047 on hosts that predate Posix 1003.1-1992, but we can't help this.
5048 Don't mishandle weird characters like space on pre-Posix hosts.
5049 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5050 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5051 AC_PROG_MKDIR_P from AS_MKDIR_P.
5052 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5053 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5054 earlier editions are not (including Automake 1.8.3).
5055 Do not suggest mkinstalldirs for thread-safety.
5056 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5057 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5058 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5059 presence of special characters and race conditions.
5060 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5061 in Autoconf's name space.
5063 2006-05-10 Bruno Haible <bruno@clisp.org>
5064 and Paul Eggert <eggert@cs.ucla.edu>
5066 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5067 from Automake with minor changes.
5068 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5070 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5072 * config/install-sh: Update to Automake CVS version, as follows:
5073 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5074 * lib/install-sh: Simplify the expr implementation of dirname.
5075 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5076 * lib/install-sh: Handle --, and diagnose unknown options.
5078 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5080 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5081 `./autom4te' to create `./testsuite', since the `all' target
5082 will ensure its presence, but `installcheck' should not create
5083 the uninstalled wrappers.
5085 * tests/torture.at (Unusual Automake input files): Skip if we
5086 detect automake < 1.8.
5088 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5090 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5091 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5092 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5095 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5097 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5098 munge (multiple) white space and other oddities.
5099 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5100 single quotes in variable assignment.
5101 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5102 and similar failures by adding multiple spaces, tabs, and other
5104 Report and different test suggested by Francesco Romani
5105 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5107 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5108 single quotes, we only need to search for single quotes; this
5109 both simplifies the search pattern, and makes us less
5110 susceptible to `echo' variations for arguments not containing
5112 (_AC_ARG_VAR_VALIDATE): Likewise.
5114 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5116 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5117 `$*' and IFS concatenation issue with traditional shells and
5118 bash-2.04. Report by Seanster@Seanster.com.
5120 2006-05-03 Bruno Haible <bruno@clisp.org>
5122 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5123 precisely which Mac OS X versions have the od problem.
5125 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5127 * doc/autoconf.texi: Use @option systematically.
5129 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5130 and Bruno Haible <bruno@clisp.org>
5132 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5134 (Integer Overflow): Mention the special case of integer division
5137 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5139 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5140 traditional shells like the Solaris one that do not use the
5141 first IFS character for assembling `$*'.
5142 Prompted by a related report from autoconf_bug@nro.ca.
5144 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5145 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5147 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5148 Mention more problems with the -e option.
5150 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5153 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5155 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5156 in URLs to improve DVI formatted output (requires texinfo 4.6).
5157 (System Services, Systemology, Shellology): Likewise.
5158 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5161 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5163 (Runtime): Fix macro argument names to match description:
5164 `action-if-found' -> `action-if-true' and similarly.
5165 (Obsolete Macros): Likewise.
5166 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5167 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5168 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5170 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5172 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5175 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5178 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5180 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
5181 /bin/sh set unsorted output.
5182 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
5183 * tests/local.at: Likewise.

5187 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
5188 (Integer Overflow, Null Pointers, Buffer Overruns):
5189 (Floating Point Portability, Exiting Portably): New sections.
5190 (Writing Test Programs): Fix some langauge. Recommend exiting
5191 with status 1, not merely nonzero. Clarify exit declaration.
5192 (Run Time): Move C exit status stuff to new Exiting Portably section.

5194 (Portable Shell): Mention the Posix shell.
5196 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5198 * bin/autoconf.as (me): Replace by as_me.
5200 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5202 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5203 since as_me isn't set yet.
5205 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5207 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5208 a few minor bugs in this area.
5210 * doc/autoconf.texi (Programming in M4sh): Comment out the
5211 documentation of AS_BASENAME, for now.
5212 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5213 (Limitations of Builtins) <basename>: Do not refer to
5215 * bin/autoconf.as (me): Don't use AS_BASENAME.
5216 (dir): Remove the unused variable.
5217 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5218 AS_DETECT_REQUIRED. All uses changed.
5219 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
5221 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

5224 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
5225 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
5226 (_AS_DIRNAME_PREPARE): Likewise.
5227 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
5228 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5229 (AS_DIRNAME): Use "dirname --".
5231 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5233 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5234 of "run time" and "run-time" changed to "runtime", for consistency.
5235 * lib/autoconf/fortran.m4: Likewise (in comment).
5236 * lib/autoconf/functions.m4: Likewise.
5237 * lib/autoconf/general.m4: Likewise.
5238 * lib/autoconf/headers.m4: Likewise.
5240 * doc/autoconf.texi (Run Time): Document the exit status situation
5241 with more accuracy and detail.
5243 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5245 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5246 Archive is not officially `GNU' any more. Update URL.
5247 (Defining Directories): Likewise
5248 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5250 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5252 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5253 newline from the `trap' code to finish `config.log'; the NetBSD
5254 /bin/sh resets the exit status after an empty command, as
5255 documented in doc/autoconf.texi.
5256 Reported by Dalibor Topic <robilad@kaffe.org>.
5258 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5260 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5261 Suggested by Bruno Haible.
5263 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5265 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5266 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5267 Instead, just list the shells that we know work.
5268 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5269 changed. Be more cautious about the _cv_ variable.
5270 * tests/tools.at (Syntax of the shell scripts): Check the
5271 _cv_ variable once, at first, to avoid an internal autoconf error
5272 when sh -n does not work.
5274 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5276 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5278 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5280 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5281 use ">&-" since we're only 99.999% sure that this is portable,
5282 and since the MinGW bug is fixed in a different way.
5283 * lib/autotest/general.m4 (AT_INIT): Likewise.
5285 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5287 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5288 before opening config.log, to avoid hitting a bug on MinGW.
5290 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5292 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5293 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5294 This works around a MinGW bug reported by Eric Paire.
5295 Make sure that all writes to the log file append to it,
5296 rather than possibly losing data.
5297 * lib/autotest/general.m4 (AT_INIT): Likewise.
5299 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5301 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5304 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5308 * configure.ac (AC_INIT): Bump to 2.59d.
5310 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5314 * Makefile.maint (news-date-check): Do not require a leading `*'
5315 before the release date in NEWS.
5317 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5318 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5320 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5321 the instantiated file do not contain the string 'datarootdir'
5322 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5323 @mandir@, replace the reference '${datarootdir}' by the value.
5324 * tests/torture.at (datarootdir workaround): New test.
5325 * NEWS: Advertise this temporary fixup.
5326 Based on a patch by Bruno Haible, reported and analyzed by
5327 Paul Eggert and Noah Misch.
5329 2006-04-12 Eric Blake <ebb9@byu.net>
5331 * tests/autotest.at (Debugging a failed test): Fix comment.
5333 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5335 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5336 all the changes since 2006-04-07.
5338 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5340 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5341 succeeded, but `ln -s file dir' failed, take care to remove the
5342 leftover target before the next test, to prevent its spurious
5343 failure; also make sure `ln file dir' works before selecting it.
5344 Thanks to Keith Marshall for pointing this out.
5347 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5348 assignments in `at_debug_args', so that we put them correctly
5349 in the `run' script.
5350 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5351 Reported by Eric Blake.
5353 2006-04-11 Eric Blake <ebb9@byu.net>
5355 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5356 top-level tests after micro-suite has been run. Used in...
5357 (Debugging a successful test, Debugging script and environment),
5358 (Debugging a failed test): ...these new tests. The first of these
5360 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5361 macro, split out from...
5362 (AT_INIT): ...here, so that using -d also generates a run script.
5363 Document that -d inhibits top-level logging.
5364 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5365 inhibits top-level logging; debug scripts are created.
5367 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5369 * tests/autotest.at (Empty test, Empty check): New test to check it.
5371 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5374 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5376 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5377 the files if a problem appears. Make the empty *.at files
5378 read-only, too. Proposed by Ralf Wildenhues.
5380 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5382 * config/Makefile.am: Add comment to force updated Makefile.in.
5384 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5385 space only patch to this file, this patch causes the Makefile.in
5386 files that include freeze.mk to be updated, and thus have a
5387 newer time stamp again, which in turn makes a pristine CVS
5388 checkout have correct time stamps.
5390 * Makefile.maint (cvs-sv): New macro, to be used..
5391 (config.guess-url_prefix, config.sub-url_prefix)
5392 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5393 point to CVS text checkout of Gnulib files.
5394 (copyright-check): Bump current year.
5395 (announcement): Do not hard-wire `./announce-gen'.
5396 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5398 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5400 (wget_files): Update config.guess, config.sub, texinfo.tex by
5401 `wget-update', now that their URLs work again.
5403 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5405 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5406 Problem noted by Paul D. Smith.
5408 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5410 * doc/autoconf.texi: Remove unused words from word list.
5411 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5412 .x-sc_trailing_space: New files.
5414 * doc/standards.texi: Sync from gnulib.
5416 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5417 `LIBOBJDIR' as experimental.
5419 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5420 with a target directory; it's internally implemented as `cp'
5421 anyway, but since Autoconf advertises the possibility to use
5422 a target directory when LN_S is `ln -s', we need to find out.
5423 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5424 analyzed by Keith Marshall <keith.marshall@total.com>.
5428 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5430 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5431 confdefs.h as-is. In general, if it has backslash-newline or the
5432 like, then it doesn't work either to sort or to remove empty
5435 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5437 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5439 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5441 * lib/autom4te.in (Automake-preselections): Preselect
5444 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5446 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5447 apostrophe within a single-quoted string, as this is the usual
5448 tradition and is easier to read than '"'"'. Don't rely on the
5449 shell treating "$/" like '$/'. Use a more-consistent indenting
5452 2006-04-09 Eric Blake <ebb9@byu.net>
5454 * tests/autotest.at (Backquote command substitution),
5455 (Multiline backquote command substitution): Remove mistaken
5456 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5458 (Parenthetical command substitution, Multiline parenthetical
5459 command substitution): here.
5461 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

5493 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
5494 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
5495 (C Compiler): Move AC_C_LONG_DOUBLE to ...
5496 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention

5525 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
5526 of the warning introduced by the 2001-08-28 change.

5534 that contains braces.
5536 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5538 Revert the patch from 2006-04-01 and only improve
5539 _AS_DETECT_BETTER_SHELL:
5541 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
5542 skip nonexistent directories.
5543 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
5544 only shell candidates which exist.
5545 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
5546 * lib/autotest/general.m4 (AT_INIT): No need to give three
5547 parameters to _AS_PATH_WALK.
5549 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
5550 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5552 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
5553 distinguish m4sugar macros.
5554 * tests/tools.at (autoupdating with aclocal and m4_include):
5555 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
5556 test case by Noah Misch <noah@cs.caltech.edu>.
5558 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5560 Revert my change from 2006-03-17, in other words:
5561 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
5563 (AS_SHELL_SANITIZE): Remove DUALCASE=1.

5567 2006-04-07 Eric Blake <ebb9@byu.net>
5569 * doc/autoconf.texi (Programming in M4sh): Document that
5570 AS_MKDIR_P exits the script on failure.
5571 * lib/autotest/general.m4: Remove redundant AS_ERROR.
5573 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5575 * config/elisp-comp, config/install-sh, config/mdate-sh,
5576 config/missing, config/mkinstalldirs: Sync from Automake.

5590 Eric Blake <ebb9@byu.net>,
5591 Paul Eggert <eggert@cs.ucla.edu>,
5592 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5594 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
5595 whether `set' quotes correctly: redirect stderr of the tested
5596 `set', and use a subshell, for Ultrix; use `sed' instead of
5597 `grep' for zsh `set' which may write binary output; match only
5598 at the beginning of a line, to avoid false positives.
5599 In order to avoid false positives by unrelated variables with
5600 multiline content, put the dump algorithm in a subshell and
5601 unset all variables containing newlines (except some which are
5602 special to the shell). Warn about cache variables that are
5605 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5607 * config/config.guess, config/config.sub, config/texinfo.tex:
5610 * tests/mktests.sh: Reword comments.

5647 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
5648 ac_config_<foo>s again, sometimes normalized, sometimes not.
5649 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
5650 (AC_CONFIG_COMMANDS): Do not do so here.
5651 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
5652 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
5653 2005-07-25 rewrite. Noticed by Noah Misch.
5655 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
5656 _AC_PRESERVE_HELP_ORDER, ...
5657 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
5659 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
5660 inside m4_expand_once; it is redundant.
5662 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
5663 for --help from Cygnus `configure.'
5665 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

5678 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
5679 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
5680 * doc/autoconf.texi (Help Formatting): New node.
5681 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
5683 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5685 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
5686 lib/autoconf/specific.m4, lib/autoconf/status.m4,
5687 lib/autoconf/types.m4, lib/autotest/general.m4,
5688 tests/mktests.sh, tests/torture.at: White space cleanup:
5689 remove some SPACE before TAB, or add quoting ('' or @&t@).
5691 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
5693 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
5695 2006-04-05 Eric Blake <ebb9@byu.net>
5697 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
5698 empty test suite works.
5699 * tests/autotest.at (Empty test suite): Remove xfail.
5701 2006-04-05 Noah Misch <noah@cs.caltech.edu>

5704 TAGS to ac_config_<foo>s.
5705 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
5706 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
5707 normalizing it, consistent it with previous releases.
5708 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
5710 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
5712 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
5713 Use simplified args that Eric Blake originally suggested.
5715 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
5717 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
5718 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
5719 Use 'comm' rather than N instances of grep; this also fixes a bug
5720 whereby substrings were incorrectly matched, causing us to not
5721 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
5722 (exclude_list): Exclude empty macros.
5723 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
5725 Use awk rather than grep -E or egrep, to avoid
5726 portability problems with regular expressions containing newlines.

5734 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
5735 a subdirectory subject to Cygnus `configure'.
5736 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
5738 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
5739 report request when we have no AC_PACKAGE_BUGREPORT.
5741 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5745 * tests/mktests.sh: Update copyright year in the header of the
5748 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
5749 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
5750 typedef'ed restricted pointer, to catch a compiler bug on
5751 HP-UX 11.x, and fix warnings so it passes with -Werror.
5752 (_AC_PROG_CC_C99): Likewise.
5753 Reported by Albert Chin <china@thewrittenword.com>.

5894 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5896 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
5897 switch all of them on and of when necessary. Fixes the bug when

6599 comparing its address. Intel's interprocedural optimization was

6618 Stepan Kasal <kasal@ucw.cz>
6620 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
6621 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
6622 make its content writable before removing it. Remove an errorneous

6651 2005-09-06 Stepan Kasal <kasal@ucw.cz>
6653 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
6654 calls, so that the final expansion of this macro is shorter.
6655 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
6656 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
6657 the cleanup there. Use AS_VAR_* macros, to be more general.
6658 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
6660 * lib/autoconf/general.m4: Use AS_IF where appropriate.

6685 "if $undefined_var;" succeeds with my shell.
6687 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
6688 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

6708 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
6709 Update limitations about when to call AC_CONFIG_HEADERS.
6710 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
6711 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
6712 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
6713 ``Configuration Actions''; fix their index entries.
6715 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
6716 options correctly. Process N-M as M-N if M is smaller than N.
6717 Process ranges correctly so that N-N will run only N.
6718 Sort and uniquify the tests that will be run. If there is more
6719 than one test, reinsert the banners for the tests.
6720 * tests/autotest.at (Keywords): Unmark XFAIL.
6722 2005-08-23 Stepan Kasal <kasal@ucw.cz>
6724 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
6725 before passing the macro name to AH_TEMPLATE.
6727 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
6728 now opens log after option processing; in particular, --version
6729 and --help do not touch config.log.

6746 Prepend to LIBS, not append, in examples.
6748 2005-08-16 Stepan Kasal <kasal@ucw.cz>
6750 When building in place, set srcdir="."; suggested by Tim Van Holder.
6752 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
6753 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
6754 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
6755 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
6756 does not mean "no --srcdir option".
6758 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6760 * tests/autoscan.at (autoscan): New file.

6772 2005-07-27 Stepan Kasal <kasal@ucw.cz>
6774 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
6775 was pushdef'ed twice while popped only once. Push it only once.

6787 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
6788 "<tab>" in comment, so that the point is understandable.
6790 2005-07-25 Stepan Kasal <kasal@ucw.cz>
6792 Rewrite substantial part of lib/autoconf/status.m4.
6793 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
6794 and CONFIG_COMMANDS are not processed in four separate loops.
6795 Instead, there is one main loop. This alows that the common code
6796 is expanded only once, thus config.status (and configure) is smaller.
6798 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
6799 the AC_LIST_FILES and cousins macros are no longer used.
6801 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
6802 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
6803 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
6804 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
6805 contain the initialization, nor the for loop, nor the associated
6806 commands; all these go to ...
6807 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
6808 _AC_OUTPUT_CONFIG_STATUS.
6809 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
6810 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
6811 (_AC_OUTPUT_FILE): The creation of the sed script ...
6812 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
6813 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
6814 _AC_OUTPUT_MAIN_LOOP.
6815 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
6816 _AC_CONFIG_COMMANDS): Use ...
6817 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
6818 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
6819 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
6820 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
6821 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
6822 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
6824 (_AC_CONFIG_UNIQUE): Update.
6825 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
6826 Replaced by this ...
6827 (_AC_LIST_TAGS): ... new common macro.
6828 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
6829 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
6830 (_AC_LIST_TAG_COMMANDS): ... new common macro.
6831 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
6832 this didn't belong to the `config commands' section.
6833 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
6834 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
6835 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
6836 to the `config commands' section either.
6837 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
6838 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
6840 ... and many changes to the comments nearby.
6842 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
6843 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
6844 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6845 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
6846 (#define header templates): The comment at the top of the generated
6847 header now includes the name(s) of the source file(s).
6849 Several unrelated small changes:
6851 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
6852 parameter to AC_DIAGNOSE.
6853 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
6854 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
6855 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
6856 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
6858 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
6859 in AC_OUTPUT doesn't double-quote it either.
6860 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
6863 2005-07-10 Stepan Kasal <kasal@ucw.cz>
6865 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
6866 versions of Portland Group compiler produce single- and double-quoted
6867 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
6868 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
6870 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
6872 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
6873 This is a corrected version of yesterday's patch.
6875 2005-07-07 Stepan Kasal <kasal@ucw.cz>
6877 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
6878 path, too; insert a "===" to emphasize the line.
6880 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
6881 ac_cv_build_alias to ac_build_alias.
6882 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
6884 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
6885 change eliminates it. Problem reported by Alexandre Duret-Lutz.
6886 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
6887 (AC_ARG_VAR): ... here.
6888 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
6891 Keep a list of all precious variables and process them with one simple
6892 for loop, instead of expanding all commands, or, OTOH, complicated
6893 processing of output of "set".
6894 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
6895 variable names in new macro...
6896 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
6897 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
6898 a loop to assign all ac_env_* and ac_cv_env_* variables.
6899 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
6901 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
6902 its value to shell variable ac_precious_vars and call
6903 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
6904 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
6905 _AC_ARG_VAR_VALIDATE.
6907 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

6925 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
6926 They are generated by the Tru64 v5.1B shell.

6935 Fix cases when the varsions of Autoconf and Autotest don't match.
6936 Reported by Noah Misch.
6937 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
6938 at_top_builddir, for compatibility with older autotest.
6939 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
6940 is not set, use at_top_builddir, for compatibility with older
6941 versions of autoconf.
6943 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
6945 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
6946 Problem reported by Patrick Welche.
6948 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
6950 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
6951 sed substitution command, so that we allow | in program prefixes
6952 and program suffixes. (& is a problem anyway; we're not fixing
6954 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
6955 configure_input, top_builddir, srcdir, etc.
6956 * lib/autotest/general.m4 (AT_INIT): Likewise, for
6957 PATH_SEPARATOR in AUTOTEST_PATH.
6959 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

6967 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
6968 directories with weird names. Apparently some people like living
6969 on the edge. However, improve the test that "pwd" actually does
6970 report a name for the working directory.

6990 document to output the default config_* lists to config.status.
6991 Don't recognize option --file, if the functionality is not there.
6992 Likewise for --header; moreover, recognize --he and --h as shortcuts
6993 for --help in that case.
6995 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
6996 matches the order of execution. No code changed.

7020 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7021 the directory specific variables; but don't call it for configure_input.
7023 2005-06-28 Derek Price <derek@ximbiot.com>
7025 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7028 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7030 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

7032 due to limitations in Make syntax. Problem reported by Alexandre
7034 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

7048 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7049 variable into diagnostic. Make the diagnostic an error, not a warning,
7050 because we really don't support spaces and suchlike in dir names.
7051 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7052 Don't worry about backslashes in srcdir; it can't happen now.

7096 * doc/autoconf.texi:
7097 Don't mention Solaris versions so much, if a
7098 problem is common to all extant versions of Solaris. Say "SunOS
7099 4" instead of "SunOS" for SunOS 4.
7100 (awk): Mention more of the limitations of traditional Awk.
7101 (cat): Don't talk about cat -v.
7103 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
7105 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
7106 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

7126 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
7128 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
7129 (.x.1): Ignore the time stamp in the .TH line when deciding whether
7130 to update the man page. That way, we don't have to check in new

7145 Problem reported by Ralf Menzel.
7147 2005-06-08 Derek Price <derek@ximbiot.com>
7149 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7150 renaming them since they are about to be redefined anyhow.
7152 2005-06-08 Derek Price <derek@ximbiot.com>
7154 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7155 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7156 Move m4_undefine to alphabetical order.
7158 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
7160 * README: Recommend GNU M4 1.4.3 or later.
7161 * doc/autoconf.texi (Introduction): Likewise.
7162 Reword to avoid some formatting glitches.
7163 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7164 Clarify explanation of HP compiler bug.
7165 Redo example output tp match current CVS snapshot.
7166 Use @example.org in email addresses when the examples
7167 might get inadvertently cut-and-pasted into user code.
7168 Remove example of autom4te usage that doesn't seem to work now.
7169 Use modern AC_INIT (except when the example is meant to be
7170 shown with Autoconf 2.13).
7171 Update ksh info for Solaris 9 and later.
7173 Modernize description of Automake versions a bit.
7174 Don't claim a future version of Autoconf is near.
7175 * doc/install.texi: Reword to avoid some formatting glitches.
7177 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7179 * doc/autoconf.texi: Add [] to examples, so that the manual
7180 follows its own advice about quoting better.
7181 Reword to avoid some formatting glitches.
7182 * doc/installt.exi: Reword to avoid some formatting glitches.
7184 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7185 Tru64 ksh pattern matching bug. Reported against Libtool by
7186 Albert Chin <libtool@mlists.thewrittenword.com> and
7187 Nicolas Joly <njoly@pasteur.fr>.
7189 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7191 m4_cdr of one-member list was [[]] (one-member list containing an
7192 empty string) instead of [] (an empty list. Callers were skewed to
7193 match this misbehaviour. As a consequence of this:
7194 - m4_foreach([x], [], [foo]) expanded to `foo', while
7195 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7196 This bug has been fixed:
7198 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7199 expand to an empty string; print error msg if called without
7201 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7202 misbehaviour; handle [] and [[]] correctly.
7204 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7206 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
7207 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
7208 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
7210 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7212 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7213 swallow records with more than 99 fields.
7214 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7215 parse the long line.
7217 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7219 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7220 swallow literals longer than 399. Reported by Ralf Wildenhues.
7221 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
7222 to workaround this limitation.
7224 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
7226 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7227 to gfortran, and make these the first two compiler names
7228 checked (following the general autoconf preference for gcc).
7230 2005-06-03 Stepan Kasal <kasal@ucw.cz>
7232 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7233 (DISTCLEANFILES): Remove $(check_SCRIPTS).
7234 (testsuite): Make sure autotest.m4f is up-to-date before using it.
7236 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
7238 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7239 expression of unbounded size when processing the --list
7240 option. This runs afoul of a limit of 399 bytes per regular
7241 expression on AIX. Problem reported by Ralf Wildenhues.
7243 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
7245 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
7246 * doc/autoconf.texi (Particular Headers): Reword example
7247 for multiline stdbool replacement.
7248 (Setting Output Variables): Reword text a bit. Don't
7249 give all the details about |#_!!_#|.
7250 Reword description of line replacement.
7252 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7254 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7255 now contain newlines, and substituted files must be referenced on
7256 a line alone; the sed scripts to substitute them are now very
7258 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
7259 commands can be put in a sed script portably.
7260 * doc/autoconf.texi (Setting Output Variables): Document above
7261 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
7262 use of multiline substitution.
7263 * tests/torture.at: No longer expect substitution of newline to fail.
7265 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
7267 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
7268 From Ralf Menzel (trivial change).
7270 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
7272 * tests/local.at: Don't attempt to check for negated character
7273 classes in shell scripts. The test was too brittle.
7275 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7277 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
7278 * doc/autoconf.texi (Limitations of Builtins): Document this
7281 2005-05-24 Stepan Kasal <kasal@ucw.cz>
7283 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
7284 common code; used in many places in the tree.
7285 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
7286 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
7288 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
7290 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
7291 messages when ac_unique_file is not found.
7292 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7293 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
7294 commands, for consistency with AC_MSG_ERROR and such.
7296 * bin/autoconf.as: Make more use of "shift 2" in option processing.
7298 * bin/Makefile.am: Merge the two rules for creating scripts.
7300 2005-05-23 Stepan Kasal <kasal@ucw.cz>
7302 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
7303 obsolete; it was never documented.
7304 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
7306 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7308 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
7309 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7310 (ac_top_builddir): ... this ...
7311 (ac_top_build_prefix): ... to this; the old name is also kept, for
7312 backward compatibility.
7313 (ac_top_builddir_sub): New variable, without the trailing slash,
7315 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
7316 * doc/autoconf.texi (Configuration Actions): Rename
7317 ac_top_builddir to ac_top_build_prefix.
7318 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
7319 at_top_builddir to at_top_build_prefix.
7320 * lib/autotest/general.m4 (AT_INIT): Likewise.
7322 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7324 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
7327 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7329 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7330 argument to m4_foreach. I guess it was necessary in the past,
7331 but I think it's a no-op now.
7333 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7335 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7336 ``cat <<_ACEOF'' commands to one.
7337 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
7338 * lib/autoconf/status.m4: On various places, use expr instead of
7340 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
7341 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
7342 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7344 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
7345 the wrong patterns between ``case'' and ``esac.'' The previous
7346 code had false positives.
7348 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
7350 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

7393 2005-05-13 Stepan Kasal <kasal@ucw.cz>
7395 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
7397 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
7398 enough arguments, similarly as in m4_bpatsubsts.
7400 2005-05-12 Stepan Kasal <kasal@ucw.cz>
7402 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
7405 2005-05-11 Stepan Kasal <kasal@ucw.cz>
7407 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
7408 for absolute directory names in one loop.
7409 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
7410 abbreviations of --version and --debug.
7412 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
7414 * doc/autoconf.texi (Autoconf Language): Be more precise about
7415 quoting rules. Problems noted by Stepan Kasal.
7416 Also, throughout this document, be more careful about white space.
7417 "blank", "white space", and "space" all have different meanings
7418 and we should be careful to say what we mean.
7420 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
7422 Fix C++ related problems reported by Werner Lemberg.
7423 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
7424 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
7425 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
7426 avoid problems with C++ and throw.
7427 * tests/compile.at: .cpp, not .cc.
7429 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
7431 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7433 * doc/autoconf.texi (Generic Functions): Typos.
7435 2005-05-02 Gary V. Vaughan <gary@gnu.org>
7437 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
7438 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
7439 set by latest automake.
7441 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7443 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
7444 outputs 0 on GNU/Linux these days.
7446 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
7448 * doc/autoconf.texi (Autoconf Language): Add more description
7449 about quoting heuristics.
7450 (Limitations of Builtins): Describe "set -" problems.
7452 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7454 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
7457 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
7458 by AC_DEFINE; it was a mistake.
7459 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
7461 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7463 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7465 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7467 * doc/autoconf.texi (External Software): Quadrigraphs are not
7468 processed correctly in AS_HELP_STRING; avoid this in the examples.
7469 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7470 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7471 comment and reduce m4_default([foo], []) to [foo].
7472 (m4_strip): Update the explanation.
7474 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7476 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7477 Remove core.conftest.* too; it's generated by Tru64 5.1.
7478 Problem reported by Jennis Pruett.
7479 * lib/autoconf/functions.m4
7480 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7481 Don't bother to remove core files; AC_RUN_IFELSE should do that
7484 2005-04-19 Stepan Kasal <kasal@ucw.cz>
7486 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
7488 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
7490 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.

7493 2005-04-15 Stepan Kasal <kasal@ucw.cz>
7495 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
7498 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
7500 * doc/autoconf.texi (External Software, Package Options): Add
7501 examples showing how to implement --with-* and --enable-* options.
7503 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
7505 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
7506 as well as configure.in. Problem reported by Gregorio Guidi.
7508 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
7510 * doc/autoconf.texi (Particular Functions): Use gnulib's current
7511 pattern for alloca snippet.

7524 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
7526 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7528 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
7529 Merge `-z option' as well for the benefit of Solaris link flags. Pass
7530 whole-archive (-zallextract, -zdefaultextract) options in the hope of
7531 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
7532 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
7534 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
7536 * NEWS: The configure command now warns you if you attempt to use
7537 a directory whose name contains a special character like space,
7539 * doc/autoconf.texi (Installation Directory Variables): Allow
7540 "," in file names. Do not use \@; it's not a portable regexp.
7541 * bin/Makefile.am (edit): Likewise.
7542 * lib/Makefile.am (edit): Likewise.
7543 * tests/Makefile.am (edit): Likewise.
7544 * tests/semantics.at: Likewise.
7545 * tests/torture.at: Likewise.
7546 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
7547 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
7548 * doc/autoconf.texi (File System Conventions): Warn about
7549 unportable file names.
7550 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
7552 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
7553 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
7554 ac_pwd, and quote srcdir.
7555 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
7557 * doc/autoconf.texi: Fix some systematic formatting problems.
7558 ".)" needs a following @: if not at the end of a sentence, and
7559 similarly for "!)". "etc." should be preceded by a comma.
7560 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
7562 2005-03-22 Bruno Haible <bruno@clisp.org>
7564 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
7565 argument is often called 'build-aux'.
7567 2005-03-07 Stepan Kasal <kasal@ucw.cz>
7569 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
7570 macro AC_TRY_LINK is obsolete.
7571 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
7574 2005-02-24 Stepan Kasal <kasal@ucw.cz>
7576 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
7577 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
7578 from a Common Lisp's `cl'.
7579 (AC_PROG_CXX): Behave according to the documentation: don't
7580 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
7581 make the variable CCC precious; use `cl.exe', not `cl'.
7583 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7584 Alexandre Duret-Lutz <adl@gnu.org>
7586 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
7587 /dev/null, as "configure" shouldn't read stdin, and this insulates
7588 us from problems (e.g., when testing for "cl"). Also, do this
7589 redirection before invoking "hostname" or "uname", and keep the
7590 original input stream available via...
7591 (AS_ORIGINAL_STDIN_FD): ... this new macro.
7592 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
7593 bother with "</dev/null" since it's now done at the top of
7595 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
7596 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7597 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7598 * doc/autoconf.texi (File Descriptor Macros): New section.
7599 (Printing Messages): Mention it.
7600 * tests/base.at (Input/Output): New test.
7602 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7604 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
7605 newline if neither \c nor -n work, as that would output two
7606 newlines. Prefer -n to \c. Reported by Stepan Kasal.
7608 2005-02-12 Stepan Kasal <kasal@ucw.cz>
7610 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
7611 This causes that any required macros inside will get before the if.
7612 * doc/autoconf.texi (autom4te.cache): A typo.
7614 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
7616 Undo previous change, except keep the change to
7617 lib/autoconf/programs.m4 that replaced grep with shell
7618 pattern-matching. This is because net-snmp configure reads stdin.
7619 Reported by Noah Misch.
7621 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
7623 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
7624 from /dev/null, as "configure" shouldn't read stdin, and this
7625 insulates us from problems (e.g., when testing for "cl").
7626 Suggested by Alexandre Duret-Lutz. Also, do this redirection
7627 before invoking "hostname" or "uname".
7628 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7629 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
7630 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
7631 "</dev/null" since it's now done at the top of 'configure'.
7632 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7633 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7634 Also, replace grep with shell pattern-matching, to save a process.
7636 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
7638 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7639 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
7640 avoid thinking that Allegro Common Lisp's "cl" command is a C++

7645 * doc/autoconf.texi (Limitations of Usual Tools): Document that

7659 Mention that shells no longer inherit IFS.
7660 Don't recommend PATH_SEPARATOR=';' so strongly.
7661 Mention that $RANDOM might expand to the empty string.
7662 "symlink" and "soft link" -> "symbolic link".
7663 Improve mktemp description (reported by Bruno Haible).

7739 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
7741 Try not to generated lines of unlimited length, as POSIX places a
7742 2047-byte limit on line length of portable text files.
7743 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
7744 Use newline as a separator, not space.

7779 Modified from a suggestion by Stepan Kasal.
7781 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

7802 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
7803 Update the long comment explaining it.
7805 m4_require no longer writes an ``is required by'' line to the
7806 execution stack. It contains only one bit of non-redundant
7807 information: that the macro was required, not called. And even
7808 this bit is useless in most situations: have you ever met a macro
7809 which both calls and requires the same macro?
7811 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
7812 (_m4_defun_pro_outer): ... only via this macro, for the outermost

7819 (_m4_require_call): Use it.
7820 * tests/m4sugar.at (m4_require): Expect output without the
7821 ``is required by'' messages.
7823 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

7857 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
7859 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
7860 Warn about newline stripping in `` and $(). Update Solaris
7862 (Limitations of Builtins): Use expr "X...", not expr "x...", as
7863 X insulates us from future changes to Posix.
7864 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
7867 2005-01-19 Stepan Kasal <kasal@ucw.cz>
7869 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

7889 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
7891 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

7913 (_m4_divert_n_stack): New macro; the expansion is
7914 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
7916 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
7917 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
7918 stored in _m4_divert_diversion or _m4_divert_dump.
7919 (m4_divert_pop): When the parameter is given, compare the symbolic
7920 name with the last diversion pushed on the stack. Previously, the
7921 current diversion was compared with the numeric value of the
7922 diversion given as the parameter.
7923 (m4_require): If the macro hasn't been expanded yet, call ...
7924 (_m4_require_call): this new macro.
7926 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7957 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

8229 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
8231 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8232 "char c = '\200';" rather than "char c = 0x80;" as the

8234 overflow on signed char hosts.
8236 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
8237 to -qlanglvl=ansi. We don't want to disable extensions.

8350 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
8351 "/usr/include", clear ac_x_includes instead of leaving it as "no"

8419 This isn't a complete fix but it's an improvement.
8421 * bin/autoconf.as (autom4te_options): New var.
8422 Use it instead of appending to AUTOM4TE, so that we can allow
8423 spaces in the build directory's absolute name.
8424 * bin/autoheader.in ($autoconf): Allow spaces in file names.

8456 * lib/autom4te.in (Automake-preselections): Preselect
8457 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8459 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8461 * lib/autom4te.in (Automake-preselections): Preselect
8462 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will

8478 useful for pkdsh, too.
8480 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
8482 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8483 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8484 Don't fail if ENV or BASH_ENV is readonly.

8497 names like "aux". Problem reported by Eric Blake.
8499 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
8500 by zero instead of array size, so that we can use any arithmetic
8501 constant expression (instead of requiring an integer constant
8502 expression). This allows us to test expressions like DBL_MAX <
8503 LDBL_MAX, which didn't conform to the C standard using the old
8505 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
8506 now that we can do floating-point tests at compile time.
8508 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8510 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8511 and LDBL_EPSILON, as the resulting expression isn't an
8512 integer constant expression and violates the C standard.
8513 Problem reported by Nelson H. F. Beebe. Also, check
8514 for "L" suffix, and check that long double doesn't have
8515 worse range or precision than double, that mixed-mode
8516 arithmetic doesn't generate a diagnostic, that double
8517 constants fit in long double.

8546 change). Patch reported by Ralf Wildenhues in
8547 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
8549 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8550 function F exists if the compiler and linker let you compile an
8551 expression like (F != 0). Recent versions of GCC optimize away
8552 the reference to F in that case, since every function address must
8553 be nonzero, so the link succeeds even if F does not exist.
8554 Problem reported by Manu in
8555 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
8557 * doc/autoconf.texi (Systemology): Standardize on the spelling of
8558 "Unix". Many uses changed.
8559 (Limitations of Builtins): Explain better why the ! command isn't
8562 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
8564 * lib/autom4te.in (Automake-preselections): Preselect
8565 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
8567 2004-05-19 Kevin Ryde <user42@zip.com.au>
8569 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
8570 referencing AC_FUNC_STRERROR_R.
8572 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
8573 note pessimistic assumption when cross compiling.
8575 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
8577 * doc/autoconf.texi (Limitations of Make): Note that BSD make
8578 (until 2004) invoked subcommands with sh -e, contra POSIX.
8579 Reported by Kevin Ryde.
8581 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
8583 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
8584 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
8585 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
8586 `test -f " /usr/bin/grep"', which _always_ failed.
8587 (AC_PROG_SED): Ditto bogus PATH fix.
8588 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
8589 requires that grep correctly supports _multiple_ `-e' options, rather
8590 than stating only that grep should accept `-e'.
8592 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
8594 Port to C99, which requires that 'exit' be declared.
8596 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
8597 to ensure that stdlib.h is included.
8598 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
8599 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
8600 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
8601 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
8602 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
8603 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
8604 when using 'exit' in a test; C99 requires that 'exit' be declared.
8606 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
8608 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
8609 now prefers 'grep' implementations that accept -e.
8610 (Limitations of Usual Tools): Describe problems of traditional
8611 egrep and fgrep with long input lines, and of traditional grep
8613 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
8614 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
8615 All callers changed. Append /usr/xpg4/bin to the PATH, for
8617 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
8618 the user with complaints about multiple -e options.
8619 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
8620 Define it with AC_PROG_GREP.
8621 * configure.ac (AC_PROG_GREP): Add.
8622 * lib/freeze.mk (GREP): New macro.
8624 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
8626 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
8627 a possible candidate only after all others fail, rather than
8628 consulting it first. This improves backward compatibility by
8629 better reflecting the way shell selection occurred in previous
8630 versions of Autoconf, and should help to avoid triggering latent
8631 problems in other packages, such as the one in Automake where zsh
8632 is not handled robustly:
8633 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
8634 Although it is not Autoconf's responsibility to work around
8635 problems in Automake, it nevertheless makes sense to avoid
8636 introducing unnecessary incompatibilites.
8638 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
8639 Gary V. Vaughan <gary@gnu.org>
8641 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
8642 how deeply nested we are when a suitable tool is found, set the
8643 ac_path_TOOL_found flag.
8644 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
8645 nested we are in this macro. Break out of all 3 nested loops if
8646 ac_path_TOOL_found is set.
8648 2004-04-21 Gary V. Vaughan <gary@gnu.org>
8650 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
8651 of the _AS_PATH_WALK loop too if GNU flavor is found.
8653 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
8655 * doc/autoconf.texi (Limitations of Make): Update documentation
8656 for `$<'. New entry `Long lines', based on a report from Simon
8657 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
8658 paragraph about DJGPP, based on a mail from Richard Dawe.
8660 2004-04-20 Paul Eggert <eggert@twinsun.com>
8662 * tests/c.at (C keywords): Don't assume that GCC supports
8663 "restrict" and "inline", as sufficiently-old GCC versions do not
8664 (also, GCC configured to be in pedantic C89 mode does not).
8665 Problem reported by Sumit Pandya in:
8666 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
8668 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
8669 consider -g to work if it generates warnings when plain compiles
8670 don't. Problem reported by Braden McDaniel in:
8671 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
8673 * doc/autoconf.texi (Slashes): New section, to document a problem
8674 reported by Jim Meyering in:
8675 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
8677 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
8678 linker output files before linking, to work around IRIX 6 linker bug.
8679 Problem reported by Rainer Orth in:
8680 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
8682 2004-04-20 Gary V. Vaughan <gary@gnu.org>
8684 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
8685 best tool so far counter rely on the tool path variable name to
8686 avoid checks for one tool being affected by the results of running
8687 the length check on a previous tool.
8689 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
8690 match expression argument, as different greps have different
8691 regular expression flavours.
8692 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
8694 (AC_PROG_EGREP): Pass 'EGREP$'.
8695 (AC_PROG_GREP): Pass 'GREP$'.
8697 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
8699 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
8700 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
8702 2004-03-29 Paul Eggert <eggert@twinsun.com>
8704 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
8705 Types, Specific Compiler Characteristics, System Services,
8706 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
8707 etc. consistently instead of 'long', 'short', 'unsigned' etc.
8708 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
8709 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
8711 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

8713 AC_TYPE_OFF_T): Likewise.
8714 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):

8720 2004-03-28 Paul Eggert <eggert@twinsun.com>
8722 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
8723 now defines HAVE_DECL_TZNAME if it is declared, when
8724 HAVE_STRUCT_TM_TM_ZONE is not defined.
8725 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
8726 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

8731 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
8732 superfluous backslashing of quotes (") in sed expressions;
8733 thanks to Paul Eggert.
8735 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
8737 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
8738 Fortran compiler is ifort, also added pghpf; thanks to Nelson
8739 H. F. Beebe for the bug report.
8741 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
8743 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
8744 quoted -cmdline argument in Portland Group compiler (bug
8745 reported by Jeffrey J. Barteet).
8747 2004-03-25 Kevin Ryde <user42@zip.com.au>
8749 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
8750 (Run Time): ... here, where it's now mentioned.

8774 * tests/mktests.sh: Do not generate tests for the
8776 * NEWS: Document these changes.
8778 * doc/autoconf.texi: Avoid macros with unbraced arguments,
8779 they make TeX hang up.

8789 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
8790 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
8793 2004-03-03 Paul Eggert <eggert@twinsun.com>
8795 * bin/Makefile.am (edit): Don't use $< in a context where
8796 POSIX doesn't require support for it. Use $@.in instead.
8797 Problem reported by Anthony N. Frasso in
8798 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
8799 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
8801 2004-02-23 Gary V. Vaughan <gary@gnu.org>
8803 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
8804 from the next generation of Libtool.
8805 * lib/autom4te.in (Autoreconf-preselections): Ditto.
8807 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8809 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
8810 is not always thread-safe. Report from Nathanael Nerode.
8812 2004-02-18 Paul Eggert <eggert@twinsun.com>
8814 Fix a dependencies problem, stemming from a Autoconf 2.59 build
8815 problem on QNX reported by Stephen Rasku in
8816 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
8818 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
8819 $(m4sh_m4f_dependencies); this removes a FIXME.
8820 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
8821 (MAINTAINERCLEANFILES): Split into pieces,
8822 one per related section. Add $(srcdir)/wrapper.in.
8824 2004-02-09 Paul Eggert <eggert@twinsun.com>
8826 * doc/autoconf.texi (Setting Output Variables): Emphasize that
8827 AC_SUBST provides no portable way to escape literal newlines.
8829 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
8830 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
8831 Darwin uses -lcrt2.o and there's little point to cataloging all
8832 the system variants. Partial fix reported by Andreas Waechter in:
8833 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
8834 for bug reported by Nelson H. F. Beebe in:

8847 refer to the correct file.
8848 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
8849 the behavior of the third argument.
8850 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
8851 correctly the behavior of the third argument. Document
8852 what the three macros that AU_DEFUN defines do. Fix
8853 warning message when the third argument includes $0
8854 (reported by Alexandre Duret-Lutz).

8857 Eric Sunshine <sunshine@sunshineco.com>
8858 Paul Eggert <eggert@twinsun.com>
8860 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

8877 use AS_INIT_WITH_SHELL_FN.
8878 * bin/autoconf.in, tests/wrapper.in: Regenerated.
8880 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

8906 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
8908 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
8909 2003 (except 1997) to the list of copyright years. This undoes
8910 the 2003-05-22 change, which removed the older years from the list.
8911 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

8917 grep or ggrep program in PATH that accepts as long lines as
8919 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
8921 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
8922 egrep and fgrep respectively if $GREP -E/-F don't work.
8923 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
8924 _AC_PROG_GREP, and AC_PROG_SED.

8955 2004-01-26 Paul Eggert <eggert@twinsun.com>
8957 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
8958 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
8959 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
8960 not <inttypes.h>. Problem reported by Tim Mooney in
8961 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
8962 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
8965 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
8966 otherwise "make check" fails because it forbids cmp (I guess
8967 because cmp treats files as binary on DOS-like systems).
8969 * tests/mktests.sh: Update copyright date to 2004, since some tests
8970 have changed in 2004.
8972 2004-01-23 Gary V. Vaughan <gary@gnu.org>
8974 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
8975 non-truncating sed or gsed program in PATH.
8976 * tests/acprograms.at: Add it.
8977 * doc/autoconf.texi (Particular Programs): Document it.
8980 2004-01-15 Paul Eggert <eggert@twinsun.com>
8982 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
8983 -std1 disables some useful extensions on Tru64. Problem reported
8985 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
8987 2004-01-14 Paul Eggert <eggert@twinsun.com>
8989 * doc/autoconf.texi (Programming in M4sh): Document that
8990 AS_MKDIR_P succeeds if the destination is a symbolic link
8991 to an existing directory.

9014 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9015 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9016 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9017 AC_COMPILE_IFELSE, since we now assume our caller invokes
9018 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9019 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9020 of AC_RUN_IFELSE; this avoids the warning mentioned above.

9502 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
9503 directory for AC_CONFIG_COMMANDS' first argument exists.
9504 This makes valid the invocation of _AC_SRCPATH that follows.
9505 Reported by Eric Sunshine.
9506 * doc/autoconf.texi (Configuration Commands): Adjust.
9508 2003-09-26 Akim Demaille <akim@epita.fr>
9510 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
9511 Reported by Ralf Corsepius.
9513 2003-09-26 Akim Demaille <akim@epita.fr>
9515 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
9517 Actually, use AU_ALIAS.
9520 2003-09-26 Paul Eggert <eggert@twinsun.com>
9522 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,

9529 The test suite are sometimes assigning timings incorrectly.
9530 Reported by Henk Krus.
9531 Diagnosed by Nicolas Joly.
9533 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
9535 Instead of making AT_help a sequence of assignments to grow
9536 $at_help_all, just make AT_help_all be the growing contents of
9537 $at_help_all, and make a single assignment in...

9549 * bin/Makefile.am (edit): Handle '@configure_input@'.
9550 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
9551 (ifnames): chmod -w.
9552 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
9553 executables, not bin/ executables! Otherwise all the magic needed
9554 to find non installed files is turned off. This caused a failure
9555 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
9556 as found in its environment (sent by tests/autoreconf): pointing
9557 to bin/autom4te that could not find its files.
9558 * tests/mktests.sh: Force the replacement of generated files, for
9559 the sake of "mv" program that are interactive when overwriting a

9571 Trivial change to support GCC's configuration procedure.

9654 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
9656 Add support for newer Fortran dialects. The F77 interface is
9657 unchanged, and continues to support Fortran 77. New FC macros
9658 correspond to all the old F77 macros, with output variables FC,
9659 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
9660 available dialect, but older dialects can be specified. There are
9661 new macros AC_FC_SRCEXT to set the source extension, and
9662 AC_FC_FREEFORM to accept free-form source files.

9699 * tests/local.at: Require 2.57.
9700 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
9701 are defaulted by AT_CHECK anyway.
9702 Use AT_CHECK_AUTOM4TE.

9780 2003-08-21 Akim Demaille <akim@epita.fr>
9782 * bin/autoheader.in (&parse_args): Use &parse_warnings and
9784 ($help): Use Autom4te::ChannelDefs::usage.
9785 * bin/autoscan.in: Use Autom4te::ChannelDefs.
9786 * lib/Autom4te/General.pm: Don't export error: you don't own it.
9788 2003-08-21 Akim Demaille <akim@epita.fr>
9790 First stab at preserving warnings between calls to autom4te,
9791 including when the cache is used.
9793 There are still several issues: (i) there are too many runs of m4
9794 (one for include, one for warnings, and some more), (ii) warnings
9795 spreading on several lines are not handled gracefully, (iii) the
9796 code meant to have the call stack display for errors does not work
9797 (its handling should move from m4 to autom4te).
9799 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
9801 (@preselect): Add m4_warn.
9802 ($exit_status): Remove, use $exit_code.
9803 ($help): Use Autom4te::ChannelDefs::usage.
9804 (&handle_m4): No longer define the m4_warnings.
9805 At each run, extract and report the warnings.
9806 Always cache the result, including if the exit status is on
9807 failure, since if nothing changes, we should result in the same
9808 failure, hence we can use the cache.
9809 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
9810 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
9812 (m4_warn): Redefine as a do-nothing: it is its invocation that
9813 matters, as warnings are now reported via traces.
9814 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
9815 the contents of m4_warn: make it _call_ m4_warn, so that tracing
9816 the latter reveals calls to the former.
9820 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
9822 2003-08-21 Akim Demaille <akim@epita.fr>
9824 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

9846 2003-08-20 Akim Demaille <akim@epita.fr>
9848 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
9849 Reported by Alexandre Duret-Lutz.

9853 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
9854 * bin/autom4te: Adjust.
9855 In particular, be Autoconf tools are really silent when properly
9856 working, bind the verbosity of the 'note' channel to $verbose.
9857 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
9858 (&xsystem, &contents): Remove, since they are exported by...

9920 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
9921 shorter column three. Add DESCRIPTION to log file content.
9923 2003-08-13 Derek Price <derek@ximbiot.com>
9925 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

9981 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
9982 not all of them. This fixes 1. the fact that when testing
9983 Autoconf there are many many config.log, 2. the incorrect use of
9984 top_srcdir to find config.log.
9985 Don't mix the detailed output of failed test with the summary of
9986 failures. Rather, append detailed log afterwards.

10081 2003-05-23 Akim Demaille <akim@epita.fr>
10083 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10084 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10085 the middle of a line).
10086 * lib/m4sugar/m4sugar.m4: Likewise.
10087 Remove useless spaces in comments.
10089 2003-05-23 Akim Demaille <akim@epita.fr>
10091 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an

10105 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10106 Remove `#include <stdlib.h>' from the list; we should never
10107 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10108 resulting namespace pollution would cause other tests to fail.
10109 Configure scripts run with some older versions of g++ and HP's
10110 aCC would fail due to such an #include. Problems reported by
10111 Matthew Mueller in <http://bugs.debian.org/120704> and by
10113 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10114 In the test, use the test declaration before including <stdlib.h>,
10115 as that's closer to how it'll be used.
10117 2003-05-23 Akim Demaille <akim@epita.fr>
10119 * doc/autoconf.texi (Header Portability): ucred.h.
10122 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10124 Overhaul Autotest's logging: generate separate log files
10125 in testsuite.dir/NNN/testsuite.log, and append them to
10126 testsuite.log instead of re-running the test verbosely.
10128 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10129 file descriptor, write 0 to at_status_file instead of setting
10130 at_status=0, initialize some new variables (at_status_file,
10131 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10132 to rerun the tests, instead append the at_group_log to the
10133 at_suite_log when a test fails.
10134 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10135 with the AS_MESSAGE_LOG_FD redirected to stdout.
10136 (AT_CLEANUP): save the output status in $at_status_file
10137 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10138 its original place.
10139 (AT_CHECK): since tests are run with a redirected stdout,
10140 and used to be re-run in verbose mode, turn some $at_verbose
10141 into echo, and don't redirect the output of testing stdout
10144 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10145 the name of the debugging directory and information about

10265 2003-05-06 Akim Demaille <akim@epita.fr>
10267 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10268 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10269 by aclocal.m4 is changed it might require the importing of another
10270 m4 extension file, i.e., aclocal must be run.

10273 (&parse_args): Use --force with aclocal if required and supported.

10287 2003-04-29 Derek Price <derek@ximbiot.com>
10289 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the

10291 (AT_CLEANUP): Add `;' to end of at_help_all.
10292 (AT_INIT): Allow --keywords to be specified more than once. When

10489 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
10490 to fix a mismatch between example and discussion.
10492 2003-02-24 Kevin Ryde <user42@zip.com.au>
10494 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
10495 format starting with "-".
10497 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
10499 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
10500 is not portable inside Makefile.
10502 2003-02-20 Akim Demaille <akim@epita.fr>
10504 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
10505 compiler says yeah, but preproc says nope, compiler is right.
10506 Conversely, prompt the reader to send a bug report to the
10507 maintainers of the package, not of Autoconf.
10509 2003-02-20 Klee Dienes <kdienes@apple.com>
10511 * bin/autoreconf.in (autoreconf_current_directory): Properly
10512 handle an empty aclocal.m4.
10514 2003-02-20 Akim Demaille <akim@epita.fr>
10516 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
10517 $ac_prefix_program.
10520 2002-12-23 Paul Eggert <eggert@twinsun.com>
10522 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10523 innocuous variant befor including <limits.h> or <assert.h>. This
10524 works around a bug reported by Albert Chin: HP-UX 11i
10525 (and earlier versions) have a <limits.h> that declares
10526 gettimeofday and many other functions.
10528 2002-12-03 Paul Eggert <eggert@twinsun.com>
10532 * NEWS, configure.ac: Update version.
10534 * doc/fdl.texi: Upgrade to FDL version 1.2.
10536 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
10537 nontrivially in main's body, so that f's external declaration is
10538 not optimized away in AIX. This should fix the bug reported by
10540 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
10542 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10543 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10544 defined, to support freestanding compilers. This should fix the
10545 bug reported by Momchil Velkov in
10546 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10548 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10549 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
10550 obsolete AC_CHECK_TYPE. The missing empty arg was reported
10551 by Simon Josefsson in
10552 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
10554 * Makefile.maint (www-gnu): New macro.
10555 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
10556 the location has moved.
10558 2002-12-02 Martin Frydl <martin@systinet.com>
10560 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
10561 \(.*\) match is too long and there is something more to be checked.

10580 Update from masters.
10582 2002-11-14 Akim Demaille <akim@epita.fr>
10584 * Makefile.maint: Sync with Bison, i.e.:
10585 (po-check): Scan .l and .y files instead of the
10586 .c and the .h files that they generate. This fixes the bug
10587 reported by Tim Van Holder in:
10588 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
10589 Look for N_ as well as for _. Try to avoid matching #define for
10593 2002-11-14 Akim Demaille <akim@epita.fr>
10595 * doc/autoconf.texi (C Compiler): Compiling several files at once.
10596 From Paul Eggert and Albert Chin-A-Young.
10598 2002-11-14 Akim Demaille <akim@epita.fr>
10600 * doc/autoconf.texi (C Compiler): Solitary backslashes.
10601 From Paul Eggert and Albert Chin-A-Young.
10603 2002-11-14 Kevin Ryde <user42@zip.com.au>
10605 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
10606 than assigning in main, to avoid HP cc +O3 optimizing it away.
10608 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
10610 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
10611 option. Process --recheck after parsing all options. Pass -q
10612 option to configure on --recheck.
10613 (AC_OUTPUT): Pass -q from configure to config.status.
10614 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
10615 arguments to record.
10616 * doc/autoconf.texi (config.status Invocation): Document
10617 config.status -q option.
10619 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
10621 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
10622 Makefile.in if Makefile.am exists.
10623 (output): Strip `.am' from Makefiles. Don't
10624 output AC_CONFIG_FILES if no Makefiles were found.
10626 2002-11-07 Akim Demaille <akim@epita.fr>
10628 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.

10644 Reported by Ezra Peisach.
10646 2002-11-05 Akim Demaille <akim@epita.fr>
10648 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
10650 We _have_ to stop using the old compatibility scheme that tried to
10651 avoid useless backslashes because Libtool 1.4.3 contains a
10652 AC_DEFINE([error_t], [int],
10653 [Define to a type to use for \`error_t' if it is not
10654 otherwise available.])
10655 We _have_ to quote the single quote and backslashes with \. The
10656 old compatibility scheme saw that ` was backslashed, and therefore
10657 did not quote the single quote. Hence before this patch, Autoconf
10658 was not compatible with Libtool.
10660 2002-11-04 Paul Eggert <eggert@twinsun.com>
10662 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

10703 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
10704 Make variable, not a shell variable.
10705 Suggested by Bruno Haible.
10707 2002-10-31 Akim Demaille <akim@epita.fr>
10709 * bin/autom4te.in (load_configuration): Reject #args out of any

10999 2002-10-22 Akim Demaille <akim@epita.fr>
11001 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
11002 characters is a syntax warning now.
11003 (_AS_QUOTE): Accept $2 as list of characters to quote.
11004 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
11005 Quote for Perl, not sh.
11006 * bin/autoheader.in: When $debug, report the file which is
11008 * tests/tools.at (autom4te, autoheader): Exercise @bar, not merely
11009 `@', to tickle Perl's lists.
11010 Reported by Carlos Velasco.
11012 2002-10-18 Akim Demaille <akim@epita.fr>
11014 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that
11015 missing included files _are_ errors.
11016 Thanks to Alexandre Duret-Lutz.
11017 * tests/tools.at (autom4te cache): Adjust.
11018 * tests/atspecific.m4 (AT_CHECK_AUTOM4TE): New.

11024 2002-10-17 Akim Demaille <akim@epita.fr>
11026 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
11027 Fixes the `AC_ARG_VAR' test failures.
11028 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
11029 * lib/freeze.mk (check-forbidden-patterns): New.

11045 2002-10-16 Akim Demaille <akim@epita.fr>
11047 Because of caching, some files that no longer exist and are no
11048 longer required can still cause errors.
11049 Reported by Alexandre Duret-Lutz.
11051 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
11052 to frozen files in @ARGV, as @ARGV must remain being a list of
11053 files. Rather, at M4 call sites, use this...
11054 (&files_to_options): New function.
11055 (&freeze): Use &error.
11056 (&up_to_date): If a file that was included according to the cache
11057 is no longer there, then the output is out dated.

11060 * tests/tools.at (autom4te cache): New.
11062 2002-10-16 Akim Demaille <akim@epita.fr>

11065 * bin/autoupdate.in (&parse_args): Kill old options.
11066 * bin/autoreconf.in (&parse_args): Remove dead options.
11068 (&autoreconf): Report the directories we enter *and leave*, so
11069 that error messages can be easily located, and use GNU Make
11070 format, so that Emacs' compile mode understands us.
11071 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11072 if some file was changed instead of `print'.
11073 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
11074 (&parse_args): Remove the dead options.

11104 2002-10-11 Akim Demaille <akim@epita.fr>
11106 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
11107 file name to enable parallel executions.
11108 From Sam Varshavchik.
11110 2002-10-08 Akim Demaille <akim@epita.fr>
11112 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11113 aclocal invocation, as Gettext macros might not be visible to
11115 Instead of blindly running autopoint, scan configure.ac (not the
11116 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11117 Reported by Paul D. Smith.
11119 2002-10-08 Paul Eggert <eggert@twinsun.com>
11121 Work around problems found when POSIXLY_CORRECT=1 is set.
11122 None of this seems to have anything to do with POSIX, really,
11123 but it's how Perl getopt works.
11124 * bin/autom4te.in (parse_args): Configure GetOpt with
11126 * doc/autoconf.texi (Invoking autom4te):
11127 --warning -> --warnings.

11149 * tests/torture.at (Configuring subdirectories): Be robust to
11150 users who use config.site to require for a cache: in this case,
11151 the two last configure runs, using two different sets of
11152 arguments, trigger a legitimate error.
11154 2002-09-28 Akim Demaille <akim@epita.fr>

11189 tests/autom4te itself.
11190 * lib/autoscan/Makefile.am: Include freeze.mk.
11191 (autoscan.list): New target --this file is no longer a source.
11192 (autoscan.pre): New file.
11194 2002-09-28 Akim Demaille <akim@epita.fr>
11196 * bin/autoscan.in (@kinds): Make them singular.

11199 tracking changes in autoscan.list.
11200 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11202 2002-09-28 Akim Demaille <akim@epita.fr>

11214 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11215 `functions' line is now prefixed with `function:'.
11216 * bin/autoscan.in (&init_tables): Adjust.
11218 2002-09-28 Akim Demaille <akim@epita.fr>
11220 From now on, autoscan files must always map a macro name to a
11221 word: there is no `default' macro for autoscan.
11223 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11225 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11228 2002-09-28 Akim Demaille <akim@epita.fr>
11230 * bin/autoscan.in (%c_keywords): Remove.
11231 (&used): Keep only track of the words we might be interested in.

11264 * doc/autoconf.texi (autoreconf Invocation): Likewise.
11266 2002-09-26 Akim Demaille <akim@epita.fr>
11268 Single suffix rules and seperated dependencies are not portable.
11270 * doc/autoconf.texi (Installation Directory Variables): Update.
11271 (Limitations of Make): Some about `Single Suffix Rules and
11272 Separated Dependencies'.
11273 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11274 (ifnames, autoscan, autom4te): Un-factor into several rules.
11276 2002-09-25 Paul Eggert <eggert@twinsun.com>
11278 * BUGS (Interoperability bugs): New section. Mention libtool
11279 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
11281 2002-09-24 Paul Eggert <eggert@twinsun.com>
11283 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
11284 make handles suffix-rules differently from GNU make.
11286 * bin/Makefile.am (SUFFIXES, .in): Remove.
11287 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
11288 Move the body of the old .in rule here.
11290 2002-09-16 Akim Demaille <akim@epita.fr>
11292 i960 compilers create `b.out' files by default.
11293 Reported by Ralf Corsepius.
11295 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
11296 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
11298 2002-09-13 Paul Eggert <eggert@twinsun.com>

11301 reference to `struct timezone' in the description of

11312 2002-09-13 Akim Demaille <akim@epita.fr>
11314 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
11315 reading config.log when the compiler is rejected.
11316 Suggested by Guido Draheim.
11318 2002-09-13 Akim Demaille <akim@epita.fr>
11320 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11321 (chdir_init) might hang when stat'ing mounted directories.
11322 Reported by Vance Shipley.
11324 2002-09-12 Akim Demaille <akim@epita.fr>
11326 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
11329 2002-09-12 Akim Demaille <akim@epita.fr>
11331 * doc/autoconf.texi (Defining Symbols): Present two different
11332 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the

11337 * doc/autoconf.texi: Review grammar and punctuation.
11339 2002-09-11 Paul Eggert <eggert@twinsun.com>
11341 * doc/autoconf.texi: Fix minor formatting, spelling, and
11343 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
11344 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
11347 2002-09-11 Akim Demaille <akim@epita.fr>
11349 * doc/autoconf.texi (Questions): Rename as...
11351 (Defining Directories): New.
11353 2002-09-09 Akim Demaille <akim@epita.fr>
11355 * doc/autoconf.texi (Making testsuite Scripts): Update.
11356 Suggested by Nishio Futoshi.
11358 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
11360 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
11361 plain `@' is wanted.
11363 2002-09-09 Akim Demaille <akim@epita.fr>
11365 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11366 `duplicates', since the algorithm was too naive and could keep
11367 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11368 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11369 Reported by Ralf Corsepius.

11376 looking for a replacement file.
11377 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11378 directory is relative.
11379 * doc/autoconf.texi (Generic Functions): Clarify the replacement
11380 directory definition.

11386 precious variables are.
11387 Suggested by Pontus Skoeld.
11389 2002-09-05 Akim Demaille <akim@epita.fr>
11391 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11392 (ifnames, autoscan, autom4te): Since we don't only depend on
11393 configure.ac variables (such as VERSION etc.), but also on prefix
11394 and so forth, depend on Makefile, not configure.ac.
11395 Reported by Alexandre Duret-Lutz.
11396 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11398 2002-09-05 Kevin Ryde <user42@zip.com.au>
11400 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes

11403 2002-09-04 Akim Demaille <akim@epita.fr>
11405 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11407 * Makefile.am (maintainer-clean-local): Remove.

11416 2002-09-03 Akim Demaille <akim@epita.fr>
11418 * configure.ac: Bump to 2.53d.
11419 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11420 as of today, on Automake's team suggestion.
11422 2002-09-03 Akim Demaille <akim@epita.fr>
11426 2002-09-02 Akim Demaille <akim@epita.fr>
11428 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
11430 * configure.ac: Disable SITE_MACRO_DIR.
11432 2002-09-02 Jim Meyering <meyering@lucent.com>
11434 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11435 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11436 Also, tweak grammar: s/make sure to/be sure to/.
11438 2002-09-02 Paul Eggert <eggert@twinsun.com>
11440 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11441 directory names are generally preferable to physical names.
11443 2002-09-02 Akim Demaille <akim@epita.fr>
11445 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11446 Reported by Raja R. Harinath.
11447 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11448 * bin/autoupdate.in: Use error instead of die.
11450 2002-09-01 Paul Eggert <eggert@twinsun.com>
11452 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11453 ordinary shell concatenation rather than echo+tr+sed command that
11454 runs afoul of a long-line-related sed bug in Solaris 8.
11456 * bin/autoheader.in (parse_args): --warning -> --warnings.
11458 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11459 stdout, as traditional "ls" does.
11460 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11461 _AC_COMPILER_EXEEXT_O): Likewise.
11462 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11464 * bin/autoconf.as: Add --prepend-include option. This patch was
11465 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11466 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11468 * bin/autoconf.in, configure: Regenerate.
11470 * doc/autoconf.texi (Special Shell Variables): Mention
11471 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11473 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11474 MAILPATH and set PS1, PS2, PS4 to default values, to work
11475 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11476 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11477 the Autoconf documentation specifies; fall back to "unset" only if
11478 this fails. Use a shell for-loop for this rather than an m4 loop,
11479 to shorten the output script.

11483 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11484 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11485 for the CDPATH problem. Document PWD.
11486 (Limitations of Builtins): Document the problem that "cd $foo" and
11487 "ls $foo" may refer to different directories in shells conforming
11488 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11489 example, since the old example is now out of date.
11491 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11492 FOO" and "ls FOO" talk about different directories; this catches
11493 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11496 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11497 of rolling our own unset.
11498 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
11499 in practice we needn't worry about CDPATH if unset doesn't work.
11501 * Makefile.in, aclocal.m4, bin/Makefile.in,
11502 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
11503 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,

11505 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
11506 tests/Makefile.in: Regenerate with Automake 1.6.3.
11508 * config/config.guess, config/config.sub, config/mkinstalldirs:
11511 * configure: Regenerate with self.

11523 2002-08-29 Akim Demaille <akim@epita.fr>
11525 * lib/Autom4te/General.pm (&xqx): New.
11526 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11527 hand, which is not portable.
11529 * bin/autom4te.in: Use them.
11530 Use &error instead of die.
11531 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11534 2002-08-17 Paul Eggert <eggert@twinsun.com>
11536 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
11537 default list of compilers to try, since it was long ago superseded
11538 by the ksh fc builtin. Suggested by Steven G. Johnson.
11540 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
11542 * doc/autoconf.texi (Invoking autom4te): End the option table,
11543 fixing a bug introduced by the previous patch.
11544 (Limitations of Make): Add a 'target lookup' subentry in the
11545 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
11547 2002-07-29 Mark D. Roth <roth@feep.net>
11549 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
11550 options and use $AUTOM4TE_PATH.
11551 * doc/autoconf.texi: Remove documentation of autom4te
11552 --include-envvar and --site-macro-subdir options and document
11553 use of $AUTOM4TE_PATH.
11554 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
11555 arguments from each language section.
11557 2002-07-29 Paul Eggert <eggert@twinsun.com>
11559 * doc/install.texi: Include copyright symbol in copyright notice.
11561 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
11563 (AM_MAKEINFOFLAGS): New macro.
11564 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
11565 * Makefile.am (INSTALL): Use the new macros.
11566 Use -o rather than --output, since "missing" does not grok --output.
11568 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11570 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
11571 comments do not always work. Never trust the exit status of
11574 2002-07-24 Kevin Ryde <user42@zip.com.au>
11576 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
11577 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
11579 2002-07-23 Paul Eggert <eggert@twinsun.com>
11581 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
11582 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
11583 apparently treats PATH="nonexistent" as if it contained ".".
11584 Bug reported by Stefan `Sec' Zehl.
11586 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11588 * doc/autoconf.texi (Limitations of Make): Mention the special

11710 2002-06-27 Paul Eggert <eggert@twinsun.com>
11712 * config/install-sh: Quote $src. Prefer || to test's -o option,
11713 as per "Limitations of Builtins".
11714 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
11715 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
11717 * tests/mktests.sh: Use grep instead of fgrep, as per
11718 "Limitations of Builtins".

11722 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
11723 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
11724 so that we consistently test the just-built programs.

11727 2002-06-12 Paul Eggert <eggert@twinsun.com>
11729 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

11741 2002-06-11 Andreas Schwab <schwab@suse.de>
11743 * doc/autoconf.texi: Add more dir entries.
11745 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
11747 * bin/autom4te.in ($cache): Don't define using `$me', the name
11748 of the cache should not depend on the name under which autom4te

11778 suggest m4_pattern_allow.
11779 Suggested by Adam J. Richter.
11781 2002-06-07 Akim Demaille <akim@epita.fr>
11783 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize

11786 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
11787 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
11788 Use ac_config_libobj_dir to find the replacement files.

11799 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp

11842 2002-05-22 Paul Eggert <eggert@twinsun.com>
11844 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
11845 from the default list of compilers to try. Suggested by
11847 * NEWS: Document the above.
11848 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
11850 2002-05-17 Paul Eggert <eggert@twinsun.com>
11852 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
11853 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
11854 This improves on an earlier suggestion by H. Peter Anvin.
11856 2002-05-16 Paul Eggert <eggert@twinsun.com>
11858 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
11859 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
11860 Both macros now accept an optional source-dir arg.
11861 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
11863 * NEWS: Document this.
11864 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
11866 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
11867 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
11868 not for GNU extensions; this undoes part of the 2000-11-03 change,
11869 reverting to 2.13-compatible behavior.
11870 Add new optional argument DIR.
11871 (AC_FUNC_FNMATCH_GNU): New macro.
11873 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
11875 2002-05-08 Paul Eggert <eggert@twinsun.com>
11877 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
11878 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
11879 and it causes a 'test' syntax error if it fails.
11880 Bug reported by Stephen Gildea.
11882 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
11883 If prototypes are supported, use them to check this at compile-time,
11884 instead of trying to check it at run-time. If we must do a run-time
11885 check, assume that setvbuf is standard when cross-compiling, as
11886 nonstandard setvbuf occurs only on ancient and unlikely hosts.
11887 Bug reported by Paul D. Smith.
11889 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
11890 argument specifying location of getloadavg.c. This removes a
11891 FIXME. This idea was taken from Jim Meyering's implementation in
11893 * doc/autoconf.texi (Particular Functions): Document this.
11894 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
11895 that's what the code does; this fixes a bug reported by
11898 2002-05-03 Akim Demaille <akim@epita.fr>
11900 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
11901 autopoint instead of gettextize.
11902 ($uses_alocal): Rename as...
11903 ($uses_aclocal): this.
11904 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11905 Suggested by Bruno Haible.
11907 2002-05-03 Akim Demaille <akim@epita.fr>
11909 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
11911 2002-04-29 Paul Eggert <eggert@twinsun.com>
11913 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
11914 files to be 1 second older; just set them to be the same time.
11915 Also, sleep 1 second after the first aclocal, to work around
11916 problems with sub-second time stamps on the input files.
11918 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
11920 * doc/autoconf.texi: Mention "set -e -x" lossage
11921 under node "Limitations of Builtins".
11923 2002-04-29 Akim Demaille <akim@epita.fr>
11925 * doc/install.texi: Better wording for setting variables when
11927 From Christian Cornelssen.
11929 2002-04-29 Akim Demaille <akim@epita.fr>
11931 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
11932 of lack of $LINENO support, then the test will compare the $LINENO
11933 in testsuite vs. the lineno in the test file. This is wrong, of
11935 Be sure to protect it.
11936 Reported by Patrick Welche.
11938 2002-04-25 Akim Demaille <akim@epita.fr>
11940 * doc/autoconf.texi (Obsolete Macros): Typo.
11941 Reported by Vladimir Volovich.
11943 2002-04-25 Akim Demaille <akim@epita.fr>
11945 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
11946 than some of the input files, hence, on the second run of aclocal,
11947 if some of its input are younger, make them older.
11948 Suggested by Paul Eggert.
11950 2002-04-25 Akim Demaille <akim@epita.fr>
11952 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

11955 2002-04-25 Akim Demaille <akim@epita.fr>
11957 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files

11962 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
11963 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the

12026 Minor spelling and grammar fixes.
12028 * doc/autoconf.texi: Follow the outline suggested in the GNU
12029 Sample Texts sections of the Texinfo 4.2 manual. Most
12030 importantly, this makes sure that the copyright notices appear in
12031 all output formats. You probably need Texinfo 4.2 to generate

12070 workaround for ${1+"$@"}.
12071 * doc/autoconf.texi (Shell Substitutions): Explain it.
12072 From Oliver Kiddle and Peter Stephenson.
12074 Have M4sh perform minimal shell sanitizing.
12076 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12078 (_AS_PREPARE): this new macro.
12080 (AS_INIT): Invoke AS_SHELL_SANITIZE.
12081 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
12083 Adjust Autoconf and Autotest.
12085 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12086 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.

12092 Use this M4sh to generate Autoconf's shell scripts.
12094 * tests/wrapsh.as: New, precursor of wrapsh.in.
12095 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12096 on Autotest and M4sh.
12097 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12098 (wrapsh.in): New target.

12132 Use dnl, not the KILL diversion.
12134 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12135 (AC_CONFIG_LINKS): here.
12137 Don't use the KILL diversion, as it kills spurious output, which
12138 results in failures being hidden.
12139 Use m4_defn where appropriate.
12140 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12141 after the second argument.
12143 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12144 syntax, as it is provided by M4sugar.

12186 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12187 to avoid versions of HP C which don't allow that.
12189 2002-03-27 Paul Eggert <eggert@twinsun.com>
12191 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

12205 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12206 as POSIX requires, as it doesn't work with Zsh.
12207 * doc/autoconf.texi (Assignments): Document the problem.
12209 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12211 * doc/autoconf.texi (Limitations of Make): Mention more issue
12212 about VPATH, overriding of macros in sub-makes, and handling of
12215 2002-03-21 Paul Eggert <eggert@twinsun.com>
12217 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12218 problem with here-document buffer boundaries.
12220 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12221 when reinvoking the shell, to work around problems with installers
12222 who put strange things like "cd" commands in their environments.

12247 (Limitations of Usual Tools): Add mkdir section.
12249 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12250 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12251 back on AS_DIRNAME to compute prefixes otherwise; this is
12252 roughly what mkinstalldirs does. That way, we need not have
12253 our own filename disassembler. The old disassembler did not
12254 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12256 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12257 Create at_test_all by a series of assignments,
12258 not by a single assignment of a long string. The latter causes ksh
12259 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12260 presumably because of a buffer overrun.
12262 2002-03-14 Paul Eggert <eggert@twinsun.com>
12264 * lib/autotest/general.m4 (at_times_skip):
12265 Renamed from at_times. Now a boolean.
12266 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12267 says 'times: not found'.

12308 subdirectory should exist.
12310 2002-03-08 Akim Demaille <akim@epita.fr>
12312 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12314 2002-03-08 Akim Demaille <akim@epita.fr>
12316 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12317 aliases the actual variables, and modifications of the former
12320 2002-03-08 Akim Demaille <akim@epita.fr>
12322 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12323 because of C-c: have m4 output in tmp files, then mv them.

12357 * doc/autoconf.texi (Transforming Names): Equality between target
12358 and host is irrelevant.
12359 (Specifying Names, Canonicalizing): Remove all references to the
12360 backward compatibility hooks. Rather, collect them all into...
12361 (Hosts and Cross-Compilation): this new section.
12362 * doc/install.texi (System Type): Ditto.
12363 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12364 that `--host' implies cross-compilation.

12368 * doc/autoconf.texi (Evaluation Macros): New.
12369 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally

12372 that it contains exactly the items, not an expression which
12373 evaluation is the current item.
12374 (m4_re_string, m4_re_word): Don't over quote them.
12376 2002-03-04 Akim Demaille <akim@epita.fr>
12378 Instead of having stacking `shift's evaluated at the end, let
12379 `foreach' loops immediately evaluate them.
12381 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12382 $*. This is the n-th time I change my mind, but hopefully this is
12385 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12387 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12388 it was only a hack for m4_text_wrap.
12389 (m4_car2): Remove, replaced by...
12391 (_m4_foreach): Adjust.
12392 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12393 m4_bpatsubst for clarification.

12469 2002-02-06 Akim Demaille <akim@epita.fr>
12471 * tests/torture.at (Configuring subdirectories): Skip if aclocal
12474 2002-02-05 Paul Eggert <eggert@twinsun.com>
12476 * doc/autoconf.texi (Specific Compiler Characteristics):
12477 Describe HP-UX cc bug workaround more accurately.
12478 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
12480 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
12481 cross-compilers, too. This undoes some of the most recent change
12484 2002-02-05 Akim Demaille <akim@epita.fr>
12486 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
12487 to make sure they are up to date when `check' is run.
12489 2002-02-05 Akim Demaille <akim@epita.fr>
12491 * doc/autoconf.texi (Making testsuite Scripts): Document
12494 2002-02-05 Akim Demaille <akim@epita.fr>
12496 * lib/freeze.mk: New.
12498 2002-02-05 Akim Demaille <akim@epita.fr>
12500 Implement `autom4te --freeze'.
12502 * bin/autom4te.in (&freeze): New.
12503 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
12504 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
12506 2002-02-05 Akim Demaille <akim@epita.fr>
12508 * bin/autom4te.in (&parse_args): Implement `frozen files are
12509 optional are the sum of the previous files on the command line'.
12510 Also, pass `--reload-state=' on them, so...
12511 (handle_m4): don't.
12512 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
12513 (M4sh): Rely on M4sugar.
12514 (Autotest, M4sh, M4sugar): Use frozen files.
12516 2002-01-31 Akim Demaille <akim@epita.fr>
12518 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
12519 * doc/autoconf.texi (Initializing configure): Adjust.
12521 2002-01-30 Akim Demaille <akim@epita.fr>
12523 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
12524 alphanumeric to `-' instead of `_'.
12526 2002-01-30 Akim Demaille <akim@epita.fr>
12528 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
12529 for plain code, the other for cross-compilation code. The latter
12530 is now run with GCC only.
12531 * doc/autoconf.texi (Compilers and Preprocessors): New.
12533 2002-01-30 Akim Demaille <akim@epita.fr>
12535 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined

12538 change AC_INIT default values.
12540 2002-01-29 Akim Demaille <akim@epita.fr>
12542 * tests/torture.at (Configuring subdirectories): Use configure.in,
12543 so that aclocal 1.4 works.
12544 Reported by Alexandre Duret-Lutz and Larry Schmitt.
12546 2002-01-28 Akim Demaille <akim@epita.fr>
12548 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
12551 2002-01-28 Akim Demaille <akim@epita.fr>
12553 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12554 AUTOTEST_PATH *after* it was set.
12555 Don't put `.' in the PATH: the user should be precise and `./' if
12556 needed. In addition, given that the test suite does some `cd', if
12557 `.' is in the path, the `tested programs' sections will report
12558 programs found in the test suite's directory, while during the
12559 tests (performed in their own directory), these programs are no
12560 longer visible. In other words, the results is confusing and
12562 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

12573 2002-01-24 Akim Demaille <akim@epita.fr>
12575 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
12576 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
12577 Bourne. Use /bin/sh.
12578 From Andreas Buening.
12580 2002-01-24 Akim Demaille <akim@epita.fr>
12582 * config/config.guess, config/config.sub, config/texinfo.tex:
12583 Update from masters.
12585 2002-01-24 Akim Demaille <akim@epita.fr>

12597 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
12598 Reported by Geir Ove Myhr.
12600 2002-01-21 Akim Demaille <akim@epita.fr>

12604 2002-01-21 Akim Demaille <akim@epita.fr>
12606 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
12607 message on invalid options.
12608 * bin/autom4te.in (parse_args): Don't use
12609 Autoconf::General::getopt with non valid options.
12611 2002-01-17 Jim Meyering <meyering@lucent.com>
12613 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
12614 $ac_cv_exeext so we don't use an old, invalid, cached value.
12616 2002-01-11 Akim Demaille <akim@epita.fr>

12628 package.m4, since is really depends upon configure.ac, not
12630 * doc/autoconf.texi (testsuite Scripts): Adjust.
12631 * tests/Makefile.am (package.m4): New.
12632 EXTRA_DIST it since its a source.
12634 2002-01-06 Akim Demaille <akim@epita.fr>
12636 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
12637 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
12638 and PACKAGE_BUGREPORT from here...
12639 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
12641 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
12642 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
12643 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
12644 * tests/tools.at (autoheader): Adjust.
12645 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
12647 2002-01-06 Akim Demaille <akim@epita.fr>

12664 * doc/autoconf.texi (New Macros): Tweak wording.
12666 2001-12-14 Akim Demaille <akim@epita.fr>
12668 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
12669 trailing files, don't apply `-rf' to files which might not be
12670 created by configure (core, core.*, and *.core), but just `rm -f'.
12671 Suggested by Jonathan Kamens.
12673 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
12675 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
12677 2001-12-14 Akim Demaille <akim@epita.fr>
12679 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
12681 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

12684 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
12685 abs_srcdir, top_srcpath to abs_top_srcdir.
12686 (_AC_OUTPUT_FILES): Adjust.
12687 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,

12697 2001-12-12 Kevin Ryde <user42@zip.com.au>
12699 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
12700 forbidden file descriptors table.
12702 2001-11-26 Akim Demaille <akim@epita.fr>
12704 * bin/autoscan.in (%c_keywords): Build it at top level.
12705 Map to 1 in order to simplify its uses.
12707 2001-11-26 Akim Demaille <akim@epita.fr>
12709 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
12710 Remove $filepath, useless.
12711 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
12712 variables, they are really part of the tokens.
12713 Split the input line on spaces and then look for tokens.
12714 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
12715 because of `lex$U.$(OBJEXT)'.
12716 (&scan_files): Use "@list" instead of join.
12717 * doc/Makefile.am (CLEANFILES): Add *.fns.
12719 2001-11-26 Akim Demaille <akim@epita.fr>

12722 Remove, replaced by...
12723 * tests/wrappl.in: Be common for all the Perl executables.
12724 In particular autoscan and autoheader want -I.
12725 * configure.ac: Adjust.
12726 * lib/autoscan/headers: errno.h is portable.
12728 2001-11-26 Akim Demaille <akim@epita.fr>
12730 * bin/autoscan.in (used): New.
12733 2001-11-26 Akim Demaille <akim@epita.fr>
12735 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
12737 (&scan_sh_file): Remove a duplicate pattern.
12738 (&check_configure_ac): Use long options.

12744 Before, having a line containing the opening of a multi line
12745 comment made the whole line be ignored.
12747 2001-11-26 Akim Demaille <akim@epita.fr>
12749 * doc/autoconf.texi (Using an Autotest Test Suite): New.

12755 Test groups are now run two directories deeper.
12757 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
12758 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
12760 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
12761 top_srcdir, builddir and top_builddir.
12762 Use `at_*dir' relatively to the directory containing the
12763 suite, use `*dir' when relatively to the current group dir.
12765 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
12767 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
12768 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
12769 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
12772 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12774 * doc/autoconf.texi (Using System Type): Add an example of `case
12775 $host' usage so people quit using `case $target' everywhere.
12777 2001-11-22 Akim Demaille <akim@epita.fr>
12779 * doc/autoconf.texi (Installation Directory Variables): Englishoes
12780 spotted by Jim Meyering.
12782 2001-11-16 Paul Eggert <eggert@twinsun.com>
12784 This patch implements a `long double' suggestion by Oliver Kiddle.
12786 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
12787 static, to catch errors if the value isn't known at compile-time
12788 and the compiler supports dynamic arrays. Change its name from
12789 `_array_' to `test_array' to avoid potential name clashes.
12790 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
12791 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
12792 better than double. Catch a bug in GCC 2.95.2 x86.
12793 * doc/autoconf.texi (C Compiler): Document the above.
12796 2001-11-13 Akim Demaille <akim@epita.fr>
12798 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
12800 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
12802 2001-11-13 Akim Demaille <akim@epita.fr>
12804 * lib/autotest/general.m4 (AT_INIT): After having run the test
12805 group, go back to the initial directory, not to at_suite_dir.
12807 2001-11-13 Akim Demaille <akim@epita.fr>
12809 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
12810 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
12811 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
12813 (AT_CHECK_CONFIGURE): Use absolute paths.
12814 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
12815 The problem is still the old one: there is no means in M4 (that I
12816 know about) to create a defining macro, because there is no means
12817 to create `$1' etc., therefore, the defining macro ``swallows''
12818 all the arguments meant to the defined macro.
12820 2001-11-13 Akim Demaille <akim@epita.fr>
12822 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
12823 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
12825 * tests/aclocal.m4: Remove, as it is no longer used.
12827 2001-11-13 Akim Demaille <akim@epita.fr>
12829 * lib/autotest/general.m4: Change `tests?' into `groups?' in
12830 variable names when referring to a single test group, or to
12831 `suite' when referring to the whole test suite.
12832 `at_last_test' is removed: m4 compute at_format itself.
12833 (at_stdout, at_stder1, at_stderr): New variables.
12834 (AT_CHECK): Use them.
12836 2001-11-13 Akim Demaille <akim@epita.fr>
12838 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
12840 Create `testsuite.dir/003/run' instead of `testsuite.003'.
12841 Do it as soon as a test fails, don't wait till the end of the test
12843 Don't remove $as_me.[0-9]*, since these files no longer exist.
12845 2001-11-13 Akim Demaille <akim@epita.fr>
12847 * tests/tools.at: Use absolute paths, since we are no longer run
12850 2001-11-13 Akim Demaille <akim@epita.fr>
12852 Now that tests are running in their own private dir, there is no
12853 need to list the files to remove at the end of tests groups.
12855 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
12856 (AT_data_files, at_data_files): Remove.
12857 (AT_CLEANUP, AT_DATA): Simplify.
12859 Remove the group dir if !debug && !failed.
12860 * tests/atspecific.m4: Adjust.
12862 2001-11-13 Akim Demaille <akim@epita.fr>
12864 Start a new layout for Autotest: `testsuite' creates
12865 `testsuite.dir' in which the at-check-line etc. files are to be
12866 found, and `testsuite.dir/003' where the test group 3 is run.
12868 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
12869 at_check_line_file, at_format, at_test_normalized, at_group_dir
12871 Create the directories.
12872 Use absolute paths for at- files.
12873 (AT_CHECK): Adjust.
12875 2001-11-11 Michael Matz <matz@kde.org>
12877 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
12879 (m4_car): Properly quote arguments.
12881 2001-11-13 Akim Demaille <akim@epita.fr>
12883 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
12884 with stricter rules on LIBOBJS.
12886 2001-11-12 Paul Eggert <eggert@twinsun.com>
12888 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
12889 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
12892 2001-11-12 Akim Demaille <akim@epita.fr>
12894 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
12896 2001-11-12 Akim Demaille <akim@epita.fr>
12898 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
12899 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
12900 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12901 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
12902 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
12903 specify to what the macro should be defined (typically to 1).
12905 2001-11-12 Akim Demaille <akim@epita.fr>
12907 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
12910 2001-11-12 Akim Demaille <akim@epita.fr>
12912 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
12913 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
12914 definition used by Automake where LEX is +/- "${missing} lex" and
12915 `missing' itself contains variables.
12917 2001-11-12 Akim Demaille <akim@epita.fr>
12919 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
12920 Now that M4sh pushes BODY, the comments were output at the end of
12923 2001-11-08 Akim Demaille <akim@epita.fr>
12925 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
12926 that we can trace macros from aclocal.m4.
12927 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
12928 obsoleted, and redirect to the former anyway.
12929 Reported by Ralf Corsepius.
12931 2001-11-08 Akim Demaille <akim@epita.fr>
12933 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
12934 processed only if present.
12935 * tests/torture.at (Configuring subdirectories): Use autoreconf
12936 instead of successive calls to autoconf.
12937 Add a nonexistent subdirectory to exercise the patch above.
12938 Reported by Ralf Corsepius.
12940 2001-11-08 Kevin Ryde <user42@zip.com.au>
12942 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
12943 doesn't accept .S files.
12945 2001-11-07 Akim Demaille <akim@epita.fr>
12947 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

12950 * bin/autom4te.in (warn_forbidden): New.
12951 (handle_output): Use it.
12952 Read m4_pattern_forbid with messages.
12954 2001-11-05 Akim Demaille <akim@epita.fr>
12956 * bin/autom4te.in (--normalize): Remove.

12993 2001-11-03 Akim Demaille <akim@epita.fr>
12995 * lib/Autom4te/General.pm (@export_vars, @export_subs)
12996 (@export_forward_subs): New.

13003 Reported by Ezra Peisach.
13005 2001-11-03 Akim Demaille <akim@epita.fr>
13007 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13008 passed on command line, defaulting to ./configure.ac if present.
13009 (&maybe_autoreconf, File::Find): Remove, unused.
13010 (&autoreconf): If autoconf is not used, don't try to trace.
13012 2001-11-02 Akim Demaille <akim@epita.fr>
13014 * configure.ac: Bump to 2.52g.
13016 2001-11-02 Akim Demaille <akim@epita.fr>
13020 2001-11-02 Akim Demaille <akim@epita.fr>
13022 * config/config.guess, config/config.sub, doc/standards.texi:
13023 * config/lispdir.m4: Update from masters.
13024 * configure.ac: Bump to 2.52f.
13026 2001-11-02 Akim Demaille <akim@epita.fr>

13029 Don't run aclocal when aclocal.m4 is not from aclocal.
13031 Don't run libtoolize and gettextize if --install is not given.
13033 2001-11-01 Paul Eggert <eggert@twinsun.com>
13035 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13036 be invoked before _AS_LINENO_PREPARE.
13037 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13038 than character ranges.
13040 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13041 invoking AS_BASENAME. Set the locale variables to 'C' if
13042 possible, as POSIX requires this to get the traditional
13044 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13046 2001-10-31 Paul Eggert <eggert@twinsun.com>
13048 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13049 with {}, as that triggers a bug in Bash 2.05.
13051 (_AS_LINENO_PREPARE): Use Sed rather than
13052 Awk. Fix the sed prepass to work even if there are multiple
13053 instances of $LINENO on the same line. Do not substitute for
13054 other variables like $LINENOT. Do not check file dates; such a
13055 check is unreliable on sufficiently fast machines, and removing
13056 the check makes the code simpler and more reliable. Check for
13057 output and chmod failures.
13059 * doc/autoconf.texi (Special Shell Variables): Document
13062 2001-10-31 Akim Demaille <akim@epita.fr>

13069 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13070 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13071 provided, while it is optional.
13072 * configure.ac: Adjust.
13074 2001-10-26 Paul Eggert <eggert@twinsun.com>
13076 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13077 lib/Autom4te/Struct.pm:
13078 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13081 * doc/autoconf.texi (Special Shell Variables): Document some
13082 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13084 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13085 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13086 eval $LINENO is not portable in practice.
13088 2001-10-24 Akim Demaille <akim@epita.fr>
13090 * lib/Autom4te/General.pm (backname): New.
13092 2001-10-24 Akim Demaille <akim@epita.fr>

13102 2001-10-22 Paul Eggert <eggert@twinsun.com>
13104 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13105 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13106 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13107 POSIX decided to standardize on the int flavor of strerror_r.
13108 Always do char* test, as there's no reason not to.
13109 Assign to a char* var, to catch strerror_r that returns int*.
13111 * doc/autoconf.texi (Particular Functions):
13112 Document the above changes. Also, document the fact that
13113 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13115 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13117 2001-10-20 Akim Demaille <akim@epita.fr>

13125 unchanged, remove the source.

13127 * bin/autoreconf.in: No longer support --m4dir.
13128 (&autoreconf): Display the full path of the configure.ac we are
13130 Trace it only once.
13131 Be sure to honor --force with gettextize.
13132 Always run aclocal.
13133 * doc/autoconf.texi: Adjust.
13135 2001-10-20 Akim Demaille <akim@epita.fr>
13137 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13139 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13140 `intl' is already present, as it refuses unless --force.
13141 (&parse_args): Use -I, --include instead of the old Autoconf
13143 ($localdir, $autoconf_dir): Remove.
13145 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13147 2001-10-19 Jens Petersen <petersen@redhat.com>
13149 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

13168 configure.ac being studied.
13170 2001-10-18 Paul Eggert <eggert@twinsun.com>
13172 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13173 long, to work around a bug in the HP C compiler version HP92453-01
13176 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13177 (AS_BASENAME_EXPR): New macro.
13178 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13179 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13180 and fall back on 'sed' only if the other two fail. This makes
13181 AS_BASENAME act more like AS_DIRNAME.
13182 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13183 contains white space.
13184 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13185 Use AS_DIRNAME, since I think it's now DOS-friendly.
13186 * tests/m4sh.at (DIRNAME_TEST): New arg $3.

13190 2001-10-10 Akim Demaille <akim@epita.fr>
13192 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

13198 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

13238 bother with $force since...
13239 * lib/Autom4te/General.pm: does.
13241 2001-10-08 Akim Demaille <akim@epita.fr>
13243 * bin/autoreconf.in: Rewrite in Perl.
13244 * configure.ac: Adjust.

13328 empty, and if we can find a shell that does support LINENO,
13329 then set CONFIG_SHELL to that shell and then re-execute
13330 ourselves with CONFIG_SHELL.
13332 2001-10-05 Paul Eggert <eggert@twinsun.com>
13334 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
13335 doesn't exist. Remove *.tmp, as a .tmp file is created during the

13405 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
13406 Don't use nested parenthesization. This patch was originally

13408 but somehow it didn't get incorporated then.
13409 * doc/autoconf.texi (Limitations of Usual Tools):

13415 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13416 Check for `expr' arithmetic overflow, and for compilation failure,
13417 and invoke a new argument $4 if either is discovered.
13418 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13419 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
13421 2001-09-28 Akim Demaille <akim@epita.fr>
13423 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

13650 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13651 Do not pass a first argument with leading '-'
13652 to expr, by parenthesizing initial integers that might be negative.
13654 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP

13658 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
13659 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check

13678 Add test for AS_BASENAME.
13679 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
13680 added test. It now correctly handles /1/2/3/, returning '3' not ''.
13681 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
13682 * tests/base.at: Fixed the expected responses. The old ones were
13684 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
13685 the documentation claims it should (and how it behaved in 2.13).
13687 2001-09-18 Akim Demaille <akim@epita.fr>
13689 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in

13700 the only optional argument is the name of the test suite.
13701 Expect `package.m4' to define the package signature.
13702 * lib/autom4te.in (Autotest): Add `package.m4?'.
13703 * tests/Makefile.am (package.m4): New.

13726 fprintf "%d" only after ensuring the argument is of type 'int'.
13727 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
13729 2001-09-17 Paul Eggert <eggert@twinsun.com>
13731 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
13732 or CFLAGS=-O5. In that case, the linker has a relaxed view of
13733 fatal errors, and AC_CHECK_LIB causes it to include libraries even
13734 when they don't exist.
13736 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
13737 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
13740 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
13741 version with the version used by fileutils 4.1, except use

13901 Be ready to handle filenames as stupid as `dnl.at', for if even
13902 the maintainer is dumb enough to do that...
13904 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
13905 excellence in M4 quotation: consider `__file__' is active.
13907 And BTW, when invoking m4, pass the --include in the right order:
13910 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

13931 * doc/autoconf.texi (autoscan Invocation): Adjust.
13933 2001-09-05 Akim Demaille <akim@epita.fr>
13935 CVS GNU M4 doesn't like `undefine(undefined)'.
13937 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
13938 New, extracted from main.
13939 Use IO::File wherever possible.
13940 (input.m4): Be constant, use -I instead of hard coding $tmp.
13941 Therefore be a quoted heredoc.
13942 Don't invoke `_au_disable', since ac was not loaded, but just

13968 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
13970 2001-08-31 Akim Demaille <akim@epita.fr>
13972 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
13973 (testsuite Scripts): There is no such thing as `atconfig.in'.
13974 And actually one diagram is missing: test suite runtime.
13976 2001-08-31 Akim Demaille <akim@epita.fr>
13978 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
13981 2001-08-31 Akim Demaille <akim@epita.fr>
13983 * bin/autoupdate.in (@include): `installcheck' revealed the path
13984 to m4sugar was lacking!
13986 2001-08-31 Akim Demaille <akim@epita.fr>
13988 * man/Makefile.am (.x.1): We really have to pass
13989 autom4te_perllibdir.

13999 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
14000 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
14001 Use directly autom4te, not autoconf.

14004 2001-08-31 Akim Demaille <akim@epita.fr>

14026 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
14027 (autoheader): Pass --force since the test suite goes too fast for
14029 Adjust to the new autoheader messages.
14031 2001-08-31 Akim Demaille <akim@epita.fr>

14043 Drop AC_MACRODIR dead for real.
14044 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14045 `autoheader: `config.hin' is created'.
14046 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14048 2001-08-31 Akim Demaille <akim@epita.fr>
14050 * bin/autoheader.in: Rewrite in Perl.

14056 Map --localdir, --autoconf-dir onto it.
14057 Forward autom4te's options instead of interpreting them.
14058 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14059 There is no such envvar since the inception of autom4te.cfg.
14060 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14061 * bin/autoupdate.in: Adjust, and perform more control.

14063 * tests/autoconf: Dittowise.
14065 2001-08-31 Akim Demaille <akim@epita.fr>

14068 * bin/autom4te.in (&find_file): Support `FILE?' standing for
14070 Use -e, not -f, since /dev/null for instance is OK.
14071 (&parse_args): Adjust.
14072 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
14074 2001-08-31 Akim Demaille <akim@epita.fr>

14081 * lib/Autom4te/General.pm (&find_peer): Remove.
14082 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14083 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14084 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14085 find the executables for it.
14086 * tests/Makefile.am: Major cleanup. Too lazy to document...
14087 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14089 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14090 indeed related to running the test suite, while passing
14091 --autoconf-dir and others is related to running non installed
14092 Autoconf executables. So don't do that, leave it to...
14093 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14094 * tests/autoscan: New.
14095 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

14100 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

14112 Suggested by Paul Eggert.
14114 2001-08-29 Akim Demaille <akim@epita.fr>
14116 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
14117 download in a tmp dir.
14119 2001-08-29 Akim Demaille <akim@epita.fr>
14121 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

14141 foo=`(command) 2>/dev/null`

14291 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
14292 the name of the directory they're in, instead of the filename,

14381 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
14382 * NEWS, README, README-alpha, TODO, tests/README: This package is
14383 `Autoconf', not `autoconf' (the executable).
14385 2001-08-20 Akim Demaille <akim@epita.fr>
14387 Info readers seem to need `Index' in the index node title :(
14389 * doc/autoconf.texi: Reverse the 2001-08-15 change which
14390 simplified index node names.

14439 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
14440 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

14503 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
14504 `$0.log' as for projects where testsuite is in src, we'd have

14521 * doc/autoconf.texi: Work around Texinfo buglets.
14522 (Transformation Rules): One example is enough, users are expected
14523 to have their brains on. And BTW, use DESTDIR.
14524 (dvar): New macro. Use it.
14526 2001-08-17 Akim Demaille <akim@epita.fr>
14528 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.
14529 * lib/autotest/general.m4 (AT_INIT): Use the relative dir when
14530 looking for ChangeLogs.
14532 2001-08-17 Akim Demaille <akim@epita.fr>
14534 * bin/autom4te.in: --normalize is a new option.

14581 autom4te.cache (it's a directory, not a file.
14582 * Makefile.am: Ditto (but maintainer-clean-local).
14584 2001-08-15 Akim Demaille <akim@epita.fr>
14586 * bin/autom4te.in (@m4_warning): New.
14587 (&handle_m4): Use it.
14588 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
14589 warnings are issued at each run.
14590 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
14591 is in the src tree.
14593 2001-08-15 Akim Demaille <akim@epita.fr>
14595 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
14596 don't waste time running `autoupdate --version' works.
14597 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
14599 2001-08-13 Akim Demaille <akim@epita.fr>

14619 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
14620 endianness for comparison instead of relying on AT_CHECK_ENV.

14658 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
14660 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
14661 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
14662 * doc/autoconf.texi (C Compiler Characteristics): Update
14663 documentation for AC_C_BIGENDIAN.
14665 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
14667 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
14668 magic values from an object file when cross-compiling.
14669 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
14671 2001-08-10 Akim Demaille <akim@epita.fr>
14673 * bin/autom4te.in (&handle_output): Don't use `grep' with side
14675 Suggested by Russ Allbery.
14677 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
14679 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
14680 current $prefix to the sub-configures.
14682 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
14684 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
14685 extension (needed on BeOS). Reported by Guido van Rossum.
14687 2001-08-09 Akim Demaille <akim@epita.fr>
14689 * bin/autom4te.in ($icache): Load it only if older than autom4te.
14691 2001-08-07 Akim Demaille <akim@epita.fr>
14693 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
14695 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
14696 No need to remove the files before and after the each test, before
14697 each test and at the end of the suite is enough.
14698 Display only the children `times', not the shell's.
14699 If the test failed or was skipped, at-times is not available.
14701 2001-08-07 Akim Demaille <akim@epita.fr>
14703 Always produce testsuite.log, including when there are no
14704 failures. This helps getting information on skipped tests, and
14705 duration of the tests. Err, implement the latter btw.
14707 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
14708 Dump information on the first run of each test.
14709 (AT_CLEANUP): Create `at-times' containing the duration of the
14712 2001-08-07 Akim Demaille <akim@epita.fr>
14714 The use of `dumpstat' revealed that `len' was used although it
14715 should not. m4_text_wrap was using it, but in the Autoconf world
14716 where it is legal. Hence (i) test M4sh in its own world, not
14717 Autoconf's, and (ii), ahem, fix the bug :)
14719 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
14720 does not like `' instead of [].
14721 (AT_INIT): Forbid `^_?AT_'.
14722 And don't output such tokens.
14723 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
14724 `script.as', and `autom4te.cache'.
14725 Remove `empty' and `macro' which are no longer used.
14726 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
14727 * tests/m4sugar.at: Use it.
14728 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
14730 2001-08-07 Akim Demaille <akim@epita.fr>
14732 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
14734 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
14736 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
14738 2001-08-04 Akim Demaille <akim@epita.fr>
14740 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
14741 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
14743 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
14744 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
14745 (AC_F77_MAIN): Likewise.
14747 2001-08-04 Akim Demaille <akim@epita.fr>
14749 Don't rely on M4sugar outputting the patterns in files, since we
14750 might process the output _without_ running m4, hence without these
14753 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
14754 * bin/autom4te.in (@Request::includes): Remove, unused.
14755 (@Request::source): Rename as...
14756 (@Request::input): this.
14757 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
14758 (&handle_output): Fetch the patterns from the traces.
14759 `$forbidden' and `$allowed' are constant: use m//o.
14760 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
14761 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
14763 2001-08-04 Akim Demaille <akim@epita.fr>
14765 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
14766 autoconf', i.e., in addition to caching traces, cache the output.
14768 * bin/autom4te.in (Request::cache): Rename as...
14769 (Request::id): this.
14770 ($cache, $icache, $tcache, $ocache): New.
14771 (&handle_m4): Save M4 output in the cache instead of $tmp.
14772 (&handle_output): Adjust.
14773 (&up_to_date_p): Check that the output cache is up to date too.
14774 (top level): Run `&handle_m4' iff force or the cache is invalid.
14775 Run `&handle_output' if the output cache is more recent.
14777 2001-08-04 Akim Demaille <akim@epita.fr>
14779 * bin/autom4te.in ($force): New.
14780 (&parse_args, &print_usage): -f, --force is a new option.
14781 (&handle_output): CPP directives might have spaces after `#'.
14782 (&parse_args): The first file only can be frozen.
14784 2001-08-04 Akim Demaille <akim@epita.fr>
14786 Don't let autom4te compute the `include' traces several times:
14787 first check that the trace cache file is up to date, and then
14788 compare its timestamp with that of the output.
14790 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
14791 the preamble. Don't require 5.005 as Autom4te::General does it,
14792 and better yet (use `use', not `require'!).
14793 * lib/Autom4te/Struct.pm: Rename the last occurrences of
14794 Class::Struct as Autom4te::Struct.
14795 * lib/Autom4te/General.pm (File::stat): Use it.
14796 (&mtime): New, export it.
14797 * bin/autom4te.in: Use it.
14798 Declare `$req' is invalid if it is outdated.
14799 Don't declare it valid before saving it if something went wrong.
14801 2001-08-04 Akim Demaille <akim@epita.fr>
14803 Autom4te shall not encode Autoconf data, and preselecting traces
14804 must be proposed to the users.
14806 * bin/autom4te.in (@required_trace): Remove.
14808 (&parse_args, &print_usage): -p, --preselect is a new option.
14809 (&up_to_date_p): Adjust.

14812 2001-08-04 Akim Demaille <akim@epita.fr>
14814 * tests/tools.at (autoconf --trace: user macros): Check traces on
14815 macros invoked without arguments, and macros invoked with multiple

14820 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
14823 2001-08-03 Akim Demaille <akim@epita.fr>
