548 Document grep peculiarity.
549 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Document
550 BSD behavior on binary input.
552 Minor testsuite improvements.
553 * lib/autotest/general.m4 (AT_INIT) <PREPARE_TESTS>: Use fewer
554 forks when sanitizing PATH. Always output machine information,
555 not just when atconfig was located.
557 Add 'testsuite -C dir'.
558 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
560 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
562 <DEFAULTS>: Delay computation of variables based on $at_dir...
563 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
564 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
565 <PARSE_ARGS>: Parse new option.
566 <HELP_TUNING>: Document it.
567 * tests/autotest.at (Choosing where testsuite is run): New test
569 (Keywords and ranges): Add test for missing -k argument.

575 * build-aux/config.guess, build-aux/config.sub,
576 build-aux/texinfo.tex: Sync from gnulib.
577 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
580 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
582 * doc/autoconf.texi (Particular Programs): Do not mention the
583 Autoconf version in which the AC_PROG_INSTALL change was done.
584 Suggested by Paul Eggert.
586 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
588 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
589 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
590 mode, we change to the source directory, also set $ac_pwd so we
591 do not go back to the build tree for the next config subdir.
592 * tests/torture.at (Deep Package): Extend test to contain two
593 config subdirs on the top level.
595 Fix parallel `maintainer-check'.
596 * Makefile.am (maintainer-check-tests): Depend on `all'.
597 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
598 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
600 (maintainer-check): Serialize the testsuite runs.
602 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'
603 in feature string for --enable/--with. Convert to underscore

624 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
626 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
627 check_SCRIPTS. Building the wrappers for `all' allows help2man
628 to use them for the manpages.
629 Report by Benoit Sigoure.
631 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
633 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
635 Fix some write failure cases in Autotest.
636 * lib/autotest/general.m4 (AT_INIT): Do not exit successfully
637 upon write failures for --help, --version, --list.
638 Guard against write failures for intermediate created scripts.
639 <at_func_create_debugging_script>: Do not make the debugging
640 script executable if it is not complete.
642 2007-12-12 Eric Blake <ebb9@byu.net>
644 Fix thinko in earlier patch - m4_join isn't defined yet.
645 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
646 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
647 (m4_require): Use m4_do, not m4_join.
649 Fix some whitespace tests on cygwin.
650 * tests/tools.at (autom4te and whitespace in file names): Restore
651 font-lock. Create $TMPDIR before it might be used.
653 Fix spurious testsuite failure with M4 1.4.11.
654 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
657 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
658 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
659 (m4_require): Avoid extra macro calls.
661 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
663 * tests/torture.at (srcdir): Fix quoting.
665 Do not pass top_srcdir to configure scripts in testsuite.
666 * tests/autotest.at (srcdir propagation): Copy install-sh to
668 (my only test): Drop setting of `top_srcdir'.
669 * tests/base.at (Input/Output): Likewise.
670 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
671 config.guess, and config.sub to test source tree.
672 Drop AC_CONFIG_AUX_DIR setting.
673 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
674 * tests/torture.at (Substitute a 2000-byte string): Drop
675 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
676 (Substitute a newline, datarootdir workaround): Likewise.
677 (Define a newline): Adjust for linenumber changes in configure.ac.
678 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
680 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
681 if `pwd` contains whitespace.
683 Quote $abs_top_srcdir in tests.
684 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
685 * tests/tools.at (Syntax of the shell scripts): Likewise.
687 * tests/m4sh.at (LINENO): Quote $0.
689 Fix testsuite program wrapper for whitespace in `pwd`.
690 The problem here is that the usual mantra is that command
691 variables can contain arguments, thus we cannot just escape
692 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
693 $top_builddir/tests directory early in $PATH, so that the
694 wrappers are found by their plain name.
695 * tests/wrapper.as: Put $testdir early in $PATH.
696 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
698 Proper config.status --file/--header and $srcdir escaping.
699 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
700 characters in $ac_file_inputs.
701 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
703 * tests/torture.at (datarootdir workaround): Adjust.
704 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
706 Fix Autotest for whitespace in `pwd`.
707 * lib/autotest/general.m4 (AT_INIT)
708 <at_func_create_debugging_script, Driver Loop>:
710 * tests/autotest.at (whitespace in absolute testdir): New test.
712 * lib/autom4te.in: Quote @datadir@.
714 Proper file name escaping in Autoconf programs and Perl modules.
715 This includes escaping of characters special to the shell
716 as well as special to Perl, e.g., leading `<' or `>'.
717 For example, when $file starts with `>', `open ">$file"'
718 wrongly tries to append to a different file.
719 * bin/autoconf.as: Fix quoting for autom4te options.
720 * lib/Autom4te/General.pm (shell_quote): New function, taken
721 from coreutils, written by Jim Meyering.
723 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
725 * bin/autoreconf.in (parse_args): Likewise.
726 * bin/autoscan.in (main): Likewise.
727 * bin/autoupdate.in (main): Likewise.
728 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
729 * bin/ifnames.in: Likewise, XFile usage fixes.
730 * tests/tools.at (autom4te and whitespace in file names): Extend
731 test. Test twice, with special characters allowed on w32, and the
732 rest. Test leading and trailing whitespace, for `open_quote'.
733 (autotools and whitespace in file names): New, analogous test.
734 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
735 by Russ Allbery and Eric Blake.
738 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
739 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
740 * lib/Autom4te/FileUtils.pm (open_quote): New function.
741 (update_file, contents): Use it.
743 * Makefile.am (autom4te-update): Rewrite for git.
745 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
747 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
750 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
751 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
753 2007-12-04 Eric Blake <ebb9@byu.net>
755 Manually resync with gnulib, since 'make cvs-update' no longer works.
756 * build-aux/config.guess: New upstream version.
757 * build-aux/config.sub: Likewise.
759 When using older automake, don't downgrade build-aux/texinfo.tex.
760 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
761 * doc/Makefile.am (TEXINFO_TEX): Add.
763 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
765 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
766 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
767 #undef as this runs afoul of our new way of creating config.h.
768 Problem reported by Jim Meyering in
769 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
771 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
773 Fix autom4te for unusual characters in input file names.
774 * bin/autom4te.in (files_to_options): Quote active characters
776 * tests/tools.at (autom4te and white space in file names):
779 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
780 Document that Tru64 awk always splits $0.
782 2007-11-24 Stepan Kasal <kasal@ucw.cz>
784 * lib/autotest/general.m4 (AT_INIT): Do not extract the
785 `#AT_STOP_...' line at the end of each test.
787 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
789 * lib/autotest/general.m4 (AT_INIT): For awk line number
790 extraction script, ensure `$at_group' has a defined value
791 even for the empty set, and properly quote its usage inside
794 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
796 * doc/autoconf.texi (Shell Functions): New chapter. Document
797 IRIX sh $0 issue in functions, move content from ...
798 (Portable Shell): ... here.
799 (Shell Script Compiler): Note that shell functions are not
800 totally unportable any more.
802 2007-11-22 Stepan Kasal <kasal@ucw.cz>
803 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
805 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
806 extracting the line numbers of the last needed test.
808 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
810 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
813 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
815 Fix IRIX testsuite debugging failures: $0 in functions.
816 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
817 Do not use $0 inside a function, as IRIX sh will set that to the
818 function name rather than the script invocation name.
820 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
821 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
823 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
824 to extract test scripts.
825 (AT_INIT): Extract and cache test script line numbers.
827 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
829 * lib/autotest/general.m4: Revert 2007-11-15 patch and
830 subsequent fixups; the awk -> here-document conversion trashes
831 performance too much with AIX sh.
833 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
835 * tests/local.at: Do not test m4, perl with AT_TESTED.
837 Diagnose and guard against write errors dealing with config.status.
838 The general idea is this: all write failures from `configure'
839 writing `config.status' are indicated by $ac_write_error, which
840 is only checked at the end. This is safe because config.status
841 code is not executed before the file is complete. Other write
842 failures, be they inside config.status, or in sub shell/awk
843 scripts spawned from configure or config.status, typically need
844 earlier checking, as their results are used right afterwards.
845 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
846 before writing config.status, check afterwards.
847 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
848 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
849 Set `ac_write_error' for write failures to config.status. Barf
850 upon write failures to temporary files.
851 Adjust note about closing and reopening the here-document.
852 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
853 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
854 reopening the here-document.
855 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
856 Ensure `ac_write_error' does not escape into config.status.
857 Also, add a couple of code paths not yet exercised in the test
858 suite: a config file with input from stdin, and a config header
860 Suggestion for catching write errors by Bruno Haible.
862 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
864 Avoid error with Tru64 awk and testsuite lines with many words.
865 * lib/autotest/general.m4 (AT_INIT): In the awk script that
866 reads the testsuite, set the field separator to an unusual value,
867 in order to not run over the limit of 199 fields. Tru64 4.0D awk
868 even splits the input if $i, i>0, was never accessed in the script.
870 Revert 2007-10-17 change.
871 * TODO: Multiline args in config files and headers mean something
872 different and are not fixed, see
873 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
874 Report by Stepan Kasal.

878 2007-11-16 Stepan Kasal <kasal@ucw.cz>
880 AC_*_TOOL does not canonicalize the prefix
881 * doc/autoconf.texi (Generic Programs): Do not say that
882 the *_TOOL macros canonicalize, they simply use the `host_alias'.
884 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
886 Diagnose write errors in config.status instantiations.
887 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
888 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
890 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
891 Extend test to also check for some write error failures, using...
892 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
893 Report by Bruno Haible.
896 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
898 (_AT_CHECK): Use less indentation, to save space.
900 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
902 Add witness macro for @top_build_prefix@ substitution.
903 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
904 (_AC_OUTPUT_FILE): Mention it here.
906 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
907 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
909 * lib/autotest/general.m4 (at_func_test): Remove.
910 (AT_INIT): Pre-extract test groups into separate files.
911 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
912 Remove at-test-source files together with the $at_group_dir.
913 * tests/autotest.at (Long test source lines): New test.
915 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
917 Shell functions and variables may share a namespace.
918 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
921 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
923 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
926 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
928 * lib/autoconf/status.m4: Fix a couple of comment typos.
930 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
932 2007-11-13 Jim Meyering <meyering@redhat.com>
934 Clean up the rule to create "expr".
935 * tests/Makefile.am (expr): Don't redirect directly to target.
936 Redirect just once, not for each echo statement.
937 Use $@, not literal "expr".
939 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
941 Don't worry about preprocessor when testing long long.
942 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
943 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
944 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
945 These no longer check for preprocessor flaws.
946 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
947 Do not check for preprocessor flaws.
949 2007-11-13 Jim Meyering <meyering@redhat.com>
951 Adapt dependencies, now that a version change doesn't modify configure.ac
952 * GNUmakefile: Remove "make clean" kludge.
953 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
955 Don't redirect directly to target.
956 Use $@, not literal "version.m4".
958 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

961 ":;{" shorthand as in previous patch.
963 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
965 * doc/autoconf.texi (Limitations of Builtins): Document problem
966 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
968 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
970 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
972 2007-11-12 Jim Meyering <meyering@redhat.com>
974 Add more non-srcdir build support.
975 * GNUmakefile (dummy): Split a long line.
976 Add -v option to autoreconf invocation.
978 Remove the autoreconf-provided INSTALL, so that we regenerate it.
979 * GNUmakefile (dummy): Remove INSTALL.
981 Remove racy commands to build scripts in bin/ and tests/.
982 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
983 are guaranteed to be built, remove the rules that tried to build
984 them. Before, with a parallel build, these rules could lead to
985 two processes writing tests/wrapper.in concurrently.
987 Build in man/ only *after* building in bin/ and tests/.
988 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
989 in both bin/ and tests/.
991 Accommodate non-srcdir build-from-checkout.
992 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
993 Use git's --git-dir=$srcdir/.git option.
994 Add quotes, in case tarball_version_file contains shell meta-characters.
995 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
996 * configure.ac: Pass "." to git-version-gen.
998 Avoid spurious test failures due to version skew.
999 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

1006 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1007 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1008 Remove `conftest.*' recursively.

1026 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1028 Ignore configure --help* errors due to LINENO-impaired shells.
1029 * tests/torture.at (Configuring subdirectories, Deep Package):
1030 In the --help* tests in read-only trees, make `.' temporarily
1031 writable again for the `stderr' file, and ignore errors due to
1032 the attempt to write configure.lineno.
1033 Report by Patrick Welche.
1035 2007-11-10 Jim Meyering <meyering@redhat.com>
1037 Generate package.m4 in build-dir, not srcdir.
1038 * tests/Makefile.am (package.m4): Adjust target.
1039 Don't redirect directly to $@.
1040 (CLEANFILES): Add package.m4.
1041 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1043 When running $(AUTOTEST), search "." before searching $(srcdir).
1045 Avoid a race condition that would make parallel "distclean" fail.
1046 * tests/Makefile.am (distclean-generic): Replace the default,
1047 automake-provided rule with an identical one, but with an additional
1048 dependency on distclean-local. Simply adding the dependency would
1049 cause automake not to emit the rule at all.
1050 * BUGS: Building with -jN works, now.
1052 Distribute git-version-gen.
1053 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1054 since GNUmakefile is distributed, and requires it for dist* rules.
1056 Remove two more generated files from version control.
1057 * INSTALL: Remove generated file.
1058 * lib/autoscan/autoscan.list: Remove generated file.
1060 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>

1082 Adjust the documentation of autotest WRT atlocal.
1083 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1084 when using Automake, to write a rule to produce atlocal, since it's
1085 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1086 distributed, not atconfig.in.

1111 "make check" to ensure that the latter passes.
1113 Use just-built tools, when possible.

1185 2007-10-28 Jim Meyering <meyering@redhat.com>
1187 Make inter-release --version output more useful.
1189 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1190 which indicates that it is built using the 19th change set
1191 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1192 is a prefix of the commit SHA1.
1193 * build-aux/git-version-gen: New file.
1194 * configure.ac: Run it to set the version.
1195 (AM_INIT_AUTOMAKE): Don't check NEWS here.

1198 * .gitignore: Add .version here, too. Just in case.
1199 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1200 not configure.ac, now that the version number changes automatically.
1202 Ensure that $(VERSION) is up to date for dist-related targets.
1203 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1204 git-version-gen doesn't match $(VERSION), but only for dist targets.

1246 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1248 Don't check for bug in HP-UX 11.00 cpp.
1249 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
1250 Use -1ull rather than -1u, since that causes problems with gnulib; see

1275 this resolution. Fixes test failure on FreeBSD.
1277 Fix config header generation with AIX awk.
1278 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
1279 script, use helper array D_is_set, as `" 0"' does not evaluate

2501 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
2502 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
2503 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
2504 works but the latter doesn't, then it's a valid type.
2505 This lets people use function types and so forth.
2506 For C++ there doesn't seem to be a simple solution, so leave it alone.
2507 (AC_CHECK_SIZEOF): Allow argument to be a variable.
2508 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

2570 2007-03-09 Stepan Kasal <kasal@ucw.cz>
2572 * doc/autoconf.texi (Specifying Names): `--host' does not
2573 change the build type.
2575 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>

2595 extra argument ACTION-IF-UNIVERSAL.
2596 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
2597 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
2598 Reindent for sanity's sake.
2600 2007-02-24 Eric Blake <ebb9@byu.net>
2602 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update

2608 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2610 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
2611 status of rm so we know when it failed.
2612 If cleaning of test dir failed before running the test, warn.
2613 Output the line separator in verbose mode before the warning
2614 to make clear the warning belongs to the following test.

2641 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
2642 input from /dev/null in awk test, so even Solaris /usr/bin/awk

2679 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
2680 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
2681 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
2682 substitution will still be done by the special code.
2683 Report by Jim Meyering.

2698 Report against Automake by Patrick Welche.
2700 2007-01-15 Stepan Kasal <kasal@ucw.cz>
2702 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
2704 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2706 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
2707 early on the reader side, drop stderr of the input to avoid
2708 `broken pipe' error output; this may happen even with shell
2709 builtin `echo' of some bash versions. Reports by Ian Macdonald
2710 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
2712 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2714 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

2725 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
2726 * doc/autoconf.texi (Signed Overflow Examples): Give more
2727 discussion about the allow_superuser_privileges example,
2728 and change it a bit to make things clearer.
2729 (Optimization and Wraparound): Clarify whether the compiler
2730 will generate an infinite loop for the example derived from
2731 Autoconf's mktime test.
2732 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
2733 Also, clarify unsigned multiplication overflow.
2735 2007-01-04 Eric Blake <ebb9@byu.net>
2737 * bin/Makefile.am (RELEASE_YEAR): New macro.
2738 (edit): Use it to supply correct copyright year to scripts.
2739 * bin/autoconf.as (version): Use it.
2740 * bin/autoheader.in ($version): Likewise.
2741 * bin/autom4te.in ($version): Likewise.
2742 * bin/autoreconf.in ($version): Likewise.
2743 * bin/autoscan.in ($version): Likewise.

2745 * bin/ifnames.in ($version): Likewise.
2747 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
2749 * doc/autoconf.texi (Integer Overflow): Revised based on today's
2750 feedback. The most important changes document what happens when
2751 you convert an out-of-range value to a signed integer type, and
2752 say that (sum < a) != (b < 0) reliably detects overflow when sum =
2755 * doc/autoconf.texi (Integer Overflow): Greatly expand and
2756 rewrite, taking notions from the recent discussion on the gcc and
2757 autoconf mailing lists; please see
2758 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
2759 and follow the many links.
2760 (Integer Overflow Basics, Signed Overflow Examples):
2761 (Optimization and Wraparound, Signed Overflow Advice):
2762 (Signed Integer Division): New sections.
2764 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
2766 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
2767 preprocessor macro arguments in traced name.
2768 * doc/autoconf.texi (Defining symbols): Document longstanding
2769 support for AC_DEFINE-ing macros with arguments, and document
2770 behavior when the same variable has multiple AC_DEFINEs.
2771 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
2772 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
2773 macros directly, giving much shorter and simpler code.
2775 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
2777 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
2778 space before "$ac_configure_args" to prevent a 'config.status
2779 --recheck' failure if ac_configure_args doesn't contain a leading
2780 space. This works around a problem with the XEmacs configure.ac,
2781 which uses the (undocumented) ac_configure_args variable
2782 inconsistently with Autoconf.
2784 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
2786 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
2787 Include <limits.h>, and use its INT_MAX to rewrite the
2788 j loop so that it does not overflow 'int'. Problem reported by
2790 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
2791 Play it safe by shifting left by 1 rather than multiplying by 2,
2792 as GCC is less likely to optimize this away when the value
2793 is signed (when it assumes overflow leads to undefined behavior).
2794 Also, don't assume time_t uses two's complement.
2796 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2798 * tests/torture.at (Substitute a 2000-byte string): Avoid using
2799 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
2800 dumps core on it. Report by Tim Rice.
2802 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2804 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
2805 --disable-option-checking to --help output even when
2806 AC_PRESERVE_HELP_ORDER is not used.
2807 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
2808 --with argument, rather than argument with [-.] replaced by
2810 * NEWS: Fix typo in previous change; the news was in the
2813 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2815 * NEWS: Warnings are now generated by default for unknown
2816 --enable-* and --with-* options.
2817 * doc/autoconf.texi (Option Checking): Renamed from
2818 (Configure Option Checking). Tighten up the wording a bit.
2819 (External Software, Package Options): Cross-reference to Option
2820 Checking, and use this to shorten our section.
2821 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
2822 "$x" to test "x$foo" != x.
2823 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
2824 Don't warn if $enable_option_checking is "no".
2825 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
2826 ac_unrecognized_opts to the empty string.
2827 Don't echo the unrecognized opts, as this might mishandle
2828 backslashes or leading -.
2829 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
2830 usage next to the other --disable-FEATURE options in the
2833 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2835 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
2836 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
2837 Print warning for unrecognized --with and --enable options
2838 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
2839 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
2840 Disable option checking when subdirs are configured.
2841 (AC_OUTPUT): If warnings are enabled, print warning about
2842 unrecognized --with and --enable options at the end of
2843 the configure output (as well as at the beginning).
2844 * doc/autoconf.texi (Option Checking): New node.
2845 Document new option warning functionality.
2847 2006-12-16 Eric Blake <ebb9@byu.net>
2849 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
2850 * NEWS: Start news for current version.
2852 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
2854 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2855 Define HAVE_GETMNTENT to 1, not to the empty string.
2856 Problem originally reported by Jochen Friedrich in
2857 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
2859 This change prompted by a problem report by Andrey Simonenko in
2860 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
2861 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
2862 object-like macros only, in the traditional portable character
2864 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
2865 Warn about attempts to define things that are not identifiers.
2866 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
2867 awful hack that AC_DEFINEd macro names containing parentheses.
2869 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
2871 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
2872 too drastic, even if Texinfo in theory requires it for info mode.
2874 (config.status Invocation): Renamed back from Recreating a
2876 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
2877 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
2879 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2881 * NEWS: Version 2.61a.
2883 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2884 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2886 * NEWS: Document changes with echo and printf, and the lack
2887 of limits on the total size of multi-line values of substituted
2888 variables, and the AC_FUNC_FSEEKO fix.
2890 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
2892 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
2893 Writing configure.ac.
2894 (Autoconf Input Layout): Renamed from configure.ac Layout.
2895 (Recreating a Configuration): Renamed from config.status Invocation.
2896 (Obsolete Recreation): Renamed from Obsolete config.status Use.
2897 (acconfig Header): Renamed from acconfig.h.
2898 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
2899 (Writing Testsuites): Renamed from Writing testsuite.at.
2900 (Autom4te Cache): Renamed from autom4te.cache.
2902 * BUGS: Remove mention of VPATH problem, since it's now documented
2903 not to be a bug in the Autoconf build procedure itself, but rather
2904 a problem with the proprietary `make' programs.
2906 * doc/autoconf.texi (Build Directories): Add a cross reference
2909 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
2910 * doc/standards.texi: Sync from gnulib.
2912 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
2913 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
2914 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
2915 generated automatically.
2917 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
2919 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
2920 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
2921 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
2923 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2925 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
2926 `CEOF$ac_eof' special marker, the awk script cannot contain a
2927 line matching `^CEOF', so this is not needed any more.
2928 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
2929 special marker in the test.
2931 2006-12-06 Stepan Kasal <kasal@ucw.cz>
2933 * tests/tools.at (autom4te preselections): Use `find -newer';
2934 remove one of the sleeps.
2936 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
2937 more readable, using ...
2938 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
2940 * doc/autoconf.texi (autoheader Invocation): Do not double-
2941 quote the parameter of `AH_BOTTOM' in the example.
2943 2006-12-05 Stepan Kasal <kasal@ucw.cz>
2945 * doc/autoconf.texi (Configuration Headers): Remove the
2946 example with multiple input files.
2947 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
2948 multiple input files.
2950 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2952 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
2953 creating the awk substitution script, handle one input line at a
2954 time, so that the maximum length of a substituted (multi-line)
2955 value is not limited by the size of the sed pattern space.
2956 The trade-off is a slightly repetitive sed script.
2957 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
2958 can only have up to 7 characters, due to Solaris 10 /bin/sed.
2959 * tests/torture.at (Substitute a 2000-byte string): Increase the
2960 test with several long lines, they should not be caught by sed
2963 * tests/tools.at (autom4te preselections): New test, to flag
2964 entries missing from autom4te.cfg.
2965 Report by David Byron <dbyron@hheld.com>.
2967 * tests/torture.at (Substitute a 2000-byte string): Actually use
2968 AC_PROG_AWK, so the last change works as intended.
2969 (Substitute and define special characters): Likewise.
2970 (Substitute a newline): Likewise.
2972 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
2973 instead of `awk' consistently.
2974 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
2975 * tests/torture.at (Torturing config.status): Test both the
2976 result of AC_PROG_AWK and plain awk.
2977 (Substitute a 2000-byte string): Likewise.
2978 (Substitute and define special characters): Likewise.
2979 (Substitute a newline): Likewise.
2981 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
2983 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
2984 can be assigned to a function pointer. Problem reported by
2985 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
2986 part of a patch by Ralf Wildenhues in that same bug report.
2988 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
2990 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
2991 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
2993 2006-12-01 Eric Blake <ebb9@byu.net>
2995 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
2996 cross-compiling from cygwin to mingw.
2997 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
2998 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
2999 to lib/autoconf/c.m4.
3001 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3003 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3004 string for more reliable failure. Wrap the entire test that
3005 causes the broken Solaris printf to dump core, in a subshell,
3006 so the segmentation fault message is reliably suppressed.
3007 Fix shell expansion errors by using /usr/ucb/echo always;
3008 avoid an error on systems without it by another subshell.
3009 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3010 subshell-$as_echo to `as_echo', for better error message.

3014 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3015 `BASH_SOURCE' contain a newline, set them to empty, as they may
3018 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3020 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3021 years and is too hard to maintain now. The last straw was
3022 reported by Jerker Baeck in
3023 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3024 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3025 * doc/autoconf.texi (Particular Functions): Move
3026 AC_FUNC_SETVBUF_REVERSED from here...
3027 (Obsolete Macros): ... to here. Say that it does nothing now.
3028 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3029 Turn into (almost) a no-op.
3031 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3033 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3034 These macros are obsolescent and new applications shouldn't need them.
3035 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3036 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3037 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3038 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3039 (AC_FUNC_VPRINTF): Likewise.
3040 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3041 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3042 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3044 * doc/autoconf.texi (Setting Output Variables): Mention that
3045 @VAR1@VAR2 has unspecified behavior. Problem reported by
3047 * NEWS: Mention this.
3049 * Makefile.am: Put only a single '#' into the copyright notice,
3050 so that it's also present in the output file. Standardize wording
3051 in makefile copyright notices to match GNU coding standards.
3052 * bin/Makefile.am: Likewise.

3065 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3067 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3068 in the sed script that mangles the awk script: delete up to the
3069 first exclamation mark only.
3070 * tests/torture.at (Substitute and define special characters):
3073 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3075 Rewrite config files generation: avoid quadratic growth in
3076 the number of substituted variables by using awk instead of sed
3077 for the bulk of the substitutions.
3078 * NEWS: Mention this.
3079 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3080 forbidden in the output (and thus input) file.
3081 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3082 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3083 generate just one large awk script for substitutions,
3084 eliminating much of the earlier complexity, while adding some
3085 new complexity. Only expand the substitution templates at
3086 configure time, for smaller configure script size. If
3087 _AC_SUBST_FILES are used, test 'awk' for working getline support
3088 at config.status time. If absent, interpolate through the
3089 shell. The awk script was written with much help
3090 from Paolo Bonzini and Paul Eggert.
3091 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3092 (_AC_SED_FRAG_NUM): Likewise.
3093 (_AC_SUBST_CMDS): Renamed from...
3094 (_AC_SED_CMDS): ...this.
3095 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3096 * tests/torture.at (Substitute a 2000-byte string): Also
3097 substitute a line with 1000 words, and a variable with several
3099 (Substitute and define special characters): Test awk special
3100 characters, and put substitution input strings `@foo@' in the
3101 output, to test that no recursion happens; test several other
3102 combinations from Paolo Bonzini.
3104 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3106 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3107 that replaced echo with AS_ECHO where this wasn't necessary.
3108 Problem reportd by Ralf Wildenhues.
3109 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3110 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3111 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3113 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3115 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3117 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3119 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3120 that traditional Awk lacks 3-arg "split". It has it.
3121 Mention that FS must be a single character, and a few other
3122 99-byte limits of traditional Awk.
3123 Mention that if (i in a) doesn't work with traditional Awk.
3125 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3127 * tests/autotest.at (BSx641-newline in command):

3129 (Newline-CODE-BS-newline in command):
3130 (Single-quote-BS-newline in command):
3131 (Single-quote-newline-BS-newline in command):
3132 Use printf '%s\n' instead of echo, for portability to hosts
3133 where echo interprets backslashes. This will break on hosts
3134 that lack printf, but for now let's assume all such hosts
3135 are dead (if not, we should get reports of test failures).
3137 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3139 'echo' has some portability problems, when given a first argument
3140 with a leading '-', or when given any argument containing '\'.
3141 Avoid using 'echo' in these cases.
3142 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

3145 * lib/autotest/general.m4 (AT_INIT): Likewise.
3146 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the

3166 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3167 * bin/autoconf.as: Redo verbose flag implementation, as the old
3168 scheme wouldn't work with AS_ECHO.
3169 * lib/autotest/general.m4 (AT_INIT): Likewise.
3170 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3171 Don't use ECHO_T, since ECHO_N is now reliable.
3172 * lib/autotest/general.m4 (AT_INIT): Likewise.
3173 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3174 rather than using a here-document to put the script into a file.
3175 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3177 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3178 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3179 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3180 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3181 * lib/autotest/general.m4 (AT_SETUP): Likewise.

3183 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3184 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3185 operand, as AS_ECHO requires. Avoid double file name expansion.
3186 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3187 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3188 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3189 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3190 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3191 Double-quote strings that would otherwise contain M4 comments.
3192 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3194 * configure.ac (AC_INIT): Bump to 2.61a.
3197 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3201 * configure.ac (AC_INIT): Bump to 2.61.
3204 * tests/autotest.at (Macro with backslash in a test title):
3205 Comment out for now, as this tests neither fails nor passes
3206 reliably. Problem reported by Ralf Wildenhues.
3208 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3210 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
3211 in previous change, which caused test failures.

3215 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
3216 code for --enable, --disable, --with, and --without to...

3321 and Stepan Kasal <kasal@ucw.cz>
3323 Handle special characters in test case titles correctly.
3324 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
3326 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
3327 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
3328 argument. Extend to check titles printed by ./micro-suite and
3329 ./micro-suite -l and the title in micro-suite.log.
3330 (Backquote in a test title,
3331 Single-quote in a test title,
3332 Double-quote in a test title): Don't expect failure anymore.
3333 (Backslash in a test title): Put a non-whitespace character after the
3334 backslash so that Bourne shells might actually see it as an escape
3336 (Brackets in a test title,
3337 Pound in a test title,
3338 Comma in a test title,
3339 Quoted Macro in a test title,

3354 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3356 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3357 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3358 5363) simply issues a warning when dividing by zero at compile
3359 time. Problem reported by Elias Pipping.
3361 2006-10-26 Eric Blake <ebb9@byu.net>
3364 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3365 show effect on macros that expand with commas.

3390 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
3392 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3393 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3394 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3395 reported by Nelson H. F. Beebe for Coreutils 6.4.
3397 * tests/tools.at (autoconf --trace: user macros): Remove test
3398 for tracing multiline macros, since m4 1.4.7a uses a different
3399 way to number lines. Problem reported by Ralf Wildenhues.

3475 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
3477 (Imported from Automake.)
3478 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3479 which incorrectly sets the mode of an existing destination
3480 directory. In some cases the unpatched install-sh could do the
3481 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3482 system. We hope this is rare in practice, but it's clearly worth
3483 fixing. Problem reported by Alex Unleashed in
3484 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3485 Also, don't bother to check for -m bugs unless we're using -m;
3486 suggested by Stepan Kasal.

3495 Report from Bruno Haible.
3497 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

3563 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
3564 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
3565 Use a better substitute, by inspecting the output of "ls"
3566 rather than just using ":".
3567 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
3568 rather than AS_EXECUTABLE_P, since we needn't worry about
3569 non-regular files here.
3571 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
3572 due to configuration hassles with this. See Tonya Underwood's report

3584 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
3585 initialization which is not inherited through the environment
3586 (_AS_BOURNE_COMPATIBLE): ... to this new macro.

3594 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
3596 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
3597 comment about ac_cpp_err; it was incorrect, and anyway
3598 ac_cpp_err is being removed below.
3599 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
3600 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
3601 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
3603 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
3604 with werror_flag and conftest.err and so forth. This is more
3605 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
3606 and anyway the user shouldn't normally want to see this gorp logged.
3607 Problem reported by Ralf Wildenhues.
3608 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
3609 empty, not 'no', since the rest of the code uses 'test -z'.
3611 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
3613 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3614 Use a single call to AC_DO_TOKENS rather than multiple, for
3616 (_AC_LINK_IFELSE): Test that resulting file is executable.
3617 Problem reported by mwoehlke in
3618 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
3620 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
3621 than creating a file to use with test -x; this is much faster.
3623 2006-10-02 Bruno Haible <bruno@clisp.org>
3625 * lib/autom4te.in (Automake-preselections): Add
3626 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.

3635 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
3636 fseeko testing program twice; just use the earlier result.
3637 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3638 Set cache var to 'unknown' (not 'no') if leaving the macro unset
3639 still doesn't let the program compile.
3640 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
3643 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
3644 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
3645 include it, without including anything else.
3646 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
3648 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

3653 `error.h', and include it, for a `error_at_line' prototype.
3654 Use a nonempty format string in the link test.
3655 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
3656 for a declaration of wait3.

3662 can apply to constants too, and that it checks for macro defns.
3663 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

3665 values. Problem reported by Ralf Wildenhues.

3880 broken lex libraries like native ia64-hp-hpux11.22; see
3881 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

4009 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
4010 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
4011 -Wundef -Werror". Problem reported by David Fang in
4012 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

4035 problems with arg script text that doesn't end in newline, and

4038 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
4040 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

4059 the compiler created a file "b.out" when it didn't create anything
4061 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):

4072 less skeptical about "volatile", after discussion with
4073 Bruno Haible on bug-gnulib.
4074 (Limitations of Usual Tools): Warn about sed stripping
4075 leading white space from text. From Bruno Haible.
4077 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4079 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
4080 compiler complains about it, even if things works after the
4081 complaint. Problem reported by Peter O'Gorman.

4102 under AC_C_VOLATILE.
4103 (Volatile Objects): Be a little less skeptical about what
4104 "volatile" means. Derived from thoughts by Ben Pfaff in
4105 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
4107 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4111 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4113 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4114 more globally, since the 2006-06-30 patch didn't suffice. Problem
4115 reported by Keith Marshall. Also, don't bother with builddir2,
4116 since it shouldn't be needed any more.
4118 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
4120 * doc/autoconf.texi (Generic compiler characteristics):
4121 Document AC_COMPUTE_INT. Fix wrong statements on Default

4135 * NEWS: Document previous change.
4137 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4139 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4140 Require that long long int be at least 64 bits wide. C99 requires
4141 this and enough programs depend on it so we should check for it.
4142 Bruno Haible reports in
4143 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4144 that long long int is 32 bits wide with some nonstandard compilers.
4145 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
4147 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4149 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4150 to a nonexistent file, so that we don't have to worry about
4151 a local site configuration that doesn't use /usr/local.
4152 Problem reported by Keith Marshall in
4153 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4155 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4157 * doc/autoconf.texi: Be more consistent about using @acronym with
4158 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4159 quite right (it talked about "OSF/Tru64", even though the
4160 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4161 and it even mentioned "OSF 4"!) and at this point there's little
4162 reason to talk about OSF any more, since it died in 1994.
4163 (Specific Compiler Characteristics): Simplify example of
4164 negative-size array.
4165 (File Descriptors): Reorder to make the text flow better.
4166 Remove joke about "appreciate the various levels"; I didn't get it.
4167 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4168 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4169 (File Descriptors, Limitations of Usual Tools):
4170 Tone down the advice against renaming or removing open files.
4171 (Limitations of Usual Tools): Add a new section, on 'rm'.
4173 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4175 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4176 -lXt in LIBS, idea from Karsten Hopp; this was due since
4179 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4180 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4181 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4182 (which belong to Xt, not X itself). See Debian bug 327655.
4184 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4186 * configure.ac (AC_INIT): Bump to 2.60a.

4193 * configure.ac, NEWS: Update.
4195 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4197 * config/texinfo.tex: Sync from upstream.
4199 * bin/autom4te.in (handle_traces): Transform the `@S|@'
4200 quadrigraph correctly in traces.
4202 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:

4206 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4208 * doc/autoconf.texi (Changed Directory Variables): New node,
4209 to document the whole `datarootdir' business a bit better.
4211 * tests/torture.at (datarootdir workaround): Extend test.
4212 Prompted by report by Alexandre Julliard.
4214 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4216 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4217 when using default mode of IBM C 6 for AIX. Problem and two-line
4218 fix reported by Larry Jones.
4220 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4222 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4223 about literal '${datarootdir}' if a definition is found in the
4226 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4228 * NEWS: Use "M4" rather than "m4" when appropriate.
4229 Problem reported by Eric Blake.
4230 * doc/autoconf.texi: Likewise.
4231 Use @acronym around BSD, GCC, and GNU when appropriate.
4232 (Why GNU M4): Renamed from "Why GNU m4".
4233 (Redefined M4 Macros): Mention that Posix
4234 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4235 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4238 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4240 * bin/autom4te.in (handle_output): Do not forbid the empty
4242 * tests/tools.at (autoconf: the empty token): New test.
4244 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4246 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4247 calls, so that we do not care whether they are LIFO or FIFO;
4248 in the m4_wrap, do not check which diversion is the topmost
4249 one, just check that the stack is balanced at the end.
4250 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4251 base diversion forever--pop the previous diversion before
4252 opening the new one; consequently, remove the m4_wrap call.
4253 * lib/autotest/general.m4 (AT_INIT): Likewise.
4254 * tests/m4sugar.at: Do not use
4255 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
4257 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4258 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4260 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4261 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4262 Rework example of m4wrap token-pasting trouble so that it doesn't
4263 care whether it's LIFO or FIFO.
4264 Fix some "contrary to"s that are awkward in English.
4266 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4268 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4269 to `yes' instead of `int$1_t' if the type is found, for more
4270 consistent configure output (where $1 is the number of bits).
4271 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4272 Suggested by Bruno Haible.
4274 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4275 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4276 with system headers. Report by Bruno Haible.
4278 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4280 * config/config.guess, config/config.sub: Sync from upstream.
4282 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4283 in order to avoid picking up an older installed frozen m4sh.m4f.
4284 Besides an outdated shell startup, this could have been created
4285 by an earlier M4 version with incompatible frozen file format.
4287 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4289 * README: Recommend m4 1.4.4 instead of 1.4.3..
4290 * doc/autoconf.texi: Likewise.
4291 (Special Chars in Names): Say that $(.FOO) is portable, as
4292 suggested by Stepan Kasal.
4293 (Installation Directory Variables, Build Directories):
4294 (Automatic Remaking, Subdirectories, Fortran Compiler):
4295 (Making testsuite Scripts, Defining Directories):
4296 Quote variable usages better.
4297 (Making testsuite Scripts): Add clean-local rule to makefile
4298 snippet, by Eric Blake.
4299 (Installation Directory Variables): Fix table item font.
4300 Reword slightly to clarify. Generalize advice about
4301 not using special characters to include all file-related
4302 vars, not just VPATH.
4303 (Special Chars in Variables): Warn about special characters in
4305 (Assignments): Clarify default-value example as suggested by
4307 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4308 (Special Shell Variables): Note leading ./ or ../, as suggested
4310 (Limitations of Builtins): Under cd, warn about CDPATH.
4311 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4314 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4316 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4317 `@var', for texi2html.
4318 (Systemology): Some more word wrapping, for DVI output.
4319 (autom4te Invocation): The short option for `--melt' is `-M',
4322 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4324 * doc/autoconf.texi: More formatting and English tweaks,
4325 many suggested by Ralf Wildenhues.
4326 Reword to avoid "@code{...}'s" and the like, since it's ugly
4327 with Emacs info mode. discontents -> woes.
4328 Put a few "will"s back. time stamp -> timestamp.
4329 side-effect -> side effect.
4331 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4333 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4334 Warn about $@ not persisting. Problem reported by Julien Danjou in
4335 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4336 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4337 Mention other special chars, too.
4339 2006-06-14 Eric Blake <ebb9@byu.net>
4341 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4343 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4345 * doc/autoconf.texi: Some systematic minor improvements, as
4346 follows. Use "makefile" when talking about makefiles
4347 generally (which might be named "makefile" or "Makefile" or even
4348 "foo.mk"), "Makefile" when talking about a specific makefile
4349 called "Makefile". This unclutters the text from weird quotes
4350 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4351 values" rather than "@var{foo}s" and similar constructs containing
4352 "}s". Use "Make rules" rather than "Makefile rules". Minor
4353 English-language improvements. Change the prefix "sub-" to "sub"
4355 Put blank lines around examples more consistently.
4356 Avoid "rather" and "very" as intensifiers.
4357 Avoid "will" as an auxiliary.
4358 (Limitations of Make): Split this node into....
4359 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4360 (Leading _ in Macro Names, Backslash-Newline-Newline):
4361 (Backslash-Newline Comments, Long Lines in Makefiles):
4362 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4363 (obj/ and Make, make -k Status, VPATH and Make):
4364 (VPATH and Double-colon, $< in Explicit Rules):
4365 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4366 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4367 New nodes, resulting from splitup of Limitations of Make.
4368 All cross-references changed. Raise the top node from
4369 a section to a chapter, and all subnodes accordingly.
4370 Redo the introductory wording to match the new organization.
4371 (Installation Directory Variables): Use an example that is
4372 closer to what Autoconf actually does. Mention that VPATH's
4373 value should not contain metacharacters or white space.
4374 (Fortran Compiler): Fix a VPATH bug in an example.
4375 (Leading _ in Macro Names): Mention that this problem is no longer
4376 of practical concern.
4377 (VPATH and Make): Reword the advice to make it clearer
4378 that Autoconf and Automake support VPATH in non-GNU make, but
4379 many packages have bugs in this area.
4380 ($< in Explicit Rules): Refer to Build Directories rather
4381 than using a (non-VPATH-safe) example.
4382 (Automatic Rule Rewriting): Mention the sort of disaster that
4383 can ensue with Solaris-style rule rewriting with VPATH.
4385 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4387 * doc/install.texi (Compilers and Options): Weaken the
4388 suggestion to use GNU make for VPATH builds.
4390 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4391 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4393 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4394 in regular expression.
4396 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4398 * doc/autoconf.texi (Installation Directory Variables):
4399 Drop extra @samp from `@table @samp' item.
4400 (Limitations of Usual Tools): Comment fix.
4401 Do not nest @samp just to point to other table items.
4402 (Writing testsuite.at) <AT_CHECK>: The second argument to
4403 `@dvar' is already @samp'ed.
4404 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4405 do not use @var in the second argument.
4407 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4409 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4410 $as_shell.exe too. Problem reported by Andreas Buening in
4411 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4413 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4415 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4416 `unused variable' compiler warning, for `-Wall -Werror'.
4417 Reported by Jaap Haitsma in
4418 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4420 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4422 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4423 case the compiler dumps core. Problem reported for
4424 OpenServer 5.0.7 by Tim Rice in
4425 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

4429 2006-06-06 Tim Rice <tim@multitalents.net>.
4431 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4432 "ERROR" only shows up in "make check" output if there is an
4435 2006-06-06 Eric Blake <ebb9@byu.net>
4437 * tests/tools.at (automatically allowed tokens): Fix typo.

4456 * config/texinfo.tex: Sync from upstream.
4458 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4459 seen, invoke libtoolize with `--ltdl' argument.
4460 * lib/autom4te.in (Autoreconf-preselections): Adjust.
4462 Suggested by Eric Blake.
4464 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

4474 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4476 * doc/autoconf.texi: Modernize some of the references to Solaris.
4478 2006-06-05 Stepan Kasal <kasal@ucw.cz>
4480 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
4481 message issued by AC_REQUIRE.
4482 * tests/m4sugar.at: Check m4_require's error message.
4483 * tests/base.at: Check AC_REQUIRE's error message.
4484 * tests/local.at (AT_CHECK_M4): New macro, almost identical
4486 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
4488 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
4489 `expout' as the last parameter.
4490 * tests/tools.at: Adapt to the above change.
4492 2006-06-04 Stepan Kasal <kasal@ucw.cz>
4494 * doc/autoconf.texi (Limitations of Usual Tools): Correct
4495 information about race-free implementations of mkdir.

4504 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
4506 * NEWS: GNU make now recommended for VPATH builds.
4507 Mention that some macros are now documented to be obsolescent.
4508 * doc/autoconf.texi:
4509 Prefer "current" to "modern" to describe
4510 currently-used (albeit perhaps old-fashioned) hosts.
4511 Mention which ancient features no longer need to be worried about.
4512 setgid -> set-group-ID
4513 setuid -> set-user-ID (these are the Posix terms)
4514 Fix some misuses of "only".
4515 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
4516 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
4517 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

4524 Mention that these macros are obsolescent.
4525 (Installation Directory Variables): shall -> should
4526 (File Descriptors): Mention that 0, 1, 2 might get reopened.
4527 Mention that it's now safe to use 3 and 4.
4528 (Limitations of Usual Tools): cp -r is now specified by Posix.
4529 Omit longwinded and obsolescent discussion of cp -f.
4530 Modernize discussion of expr, ls.
4531 (Limitations of Make): Modernize discussion of VPATH builds.
4532 Mention $? as a workaround in some cases.
4533 * doc/install.texi (Basic Installation):
4534 Mention "./configure; make; make install" first. Be more
4535 specific about why this file is generic. Remove unnecessary
4536 parens. Remove misleading "only". Remove obsolete advice
4537 about csh. Don't say "configure" takes awhile; say it
4538 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
4539 and CC=c99 rather than CC=c89, as these are blessed by current
4540 Posix. Recommend GNU make if doing a VPATH build.
4542 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
4544 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
4545 examples involving shell prompts.

4548 and Paul Eggert <eggert@cs.ucla.edu>
4550 * doc/autoconf.texi (Here-Documents): Add details about the
4551 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
4552 use "here-documents" instead of "here documents".
4554 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4556 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

4560 * doc/autoconf.texi (File System Conventions): Warn about ":"
4561 anywhere in directory names.
4563 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
4565 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
4566 about quoting the case statement, just in case.
4567 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
4568 was fixed in ksh93g; reported by Ralf Wildenhues.
4570 2006-05-31 Stepan Kasal <kasal@ucw.cz>
4572 * doc/autoconf.texi (System Services): Do not document

4579 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4581 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
4582 argument with leading hyphen. Problem reported by Paul Eggert.
4584 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4586 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
4587 about quoting ac_try: quote all of it, if any of it seems suspicious.
4588 This means we don't have to worry about ${ or sed any more.
4589 Also, double-quote the case statement, to work around misuses via
4590 underquoting as reported by Ralf Wildenhues in
4591 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
4592 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
4593 undocumented and dangerous macro.

4605 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
4606 since evidently some packages rely on the old, broken behavior.
4607 Problem reported by Ralf Wildenhues in
4608 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
4609 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
4610 pre-2006-05-26 definitions, but leave in the comments that
4611 these macros are dangerous and should not be used.
4612 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
4613 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
4614 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
4615 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
4616 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
4618 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4620 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
4621 the use of 'tr', since this is our only use of 'tr'.
4623 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4624 and Paul Eggert <eggert@cs.ucla.edu>
4626 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
4627 Don't assume 'grep' works on long lines, since AIX grep doesn't.
4629 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4631 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
4632 the output file in the `${datarootdir}' test.
4634 2005-05-28 Stepan Kasal <kasal@ucw.cz>
4635 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4637 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
4638 mention of `datarootdir' in the input file(s), but literal
4639 `${datarootdir}' in the output file, and we haven't warned yet,
4640 then warn as well: the user may have (erroneously) used
4641 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
4642 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
4643 * tests/torture.at (datarootdir workaround): Extend this test.
4646 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4647 and Paul Eggert <eggert@cs.ucla.edu>
4649 * doc/autoconf.texi (autoheader Invocation): The first argument to
4650 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
4651 alternatives and clear up the language a bit.
4653 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
4655 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
4656 ac_config_guess, ac_config_sub, ac_configure.
4657 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4658 Fix typo that prevented an unnecessary space from being removed.
4659 Problems reported by Ralf Wildenhues in:
4660 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
4662 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4664 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
4665 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
4666 Don't use the term "thread-safe" to talk about mkdir race
4667 conditions, since the problem is more a process than a thread
4668 issue. Problem reported by Stepan Kasal in:
4669 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
4670 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
4671 the test for 'install' more closely. Look at MKDIR_P first.
4672 Look in the PATH, and at /opt/sfw/bin.
4673 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
4674 Don't bother to try mkdir -p, since we already check mkdir --version;
4675 just look at the version number. (There's no easy way to check
4676 for race-free implementations.)
4677 * tests/tools.at (autoconf: subdirectories): Adjust to above
4678 changes, since MKDIR_P now might end in "/mkdir -p".
4680 * doc/autoconf.texi (autoheader Invocation): Mention that the
4681 first arg of AC_DEFINE_UNQUOTED must be a literal.
4682 Problem reported by Ben Pfaff in
4683 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
4685 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
4686 * doc/autoconf.texi (Special Chars in Variables): New section.
4687 (Preset Output Variables): Warn about special chars in CPPFLAGS.
4688 (Installation Directory Variables): Quote $(datadir) better.
4689 (Limitations of Builtins): Describe some of eval's trickiness.
4691 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
4692 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
4693 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
4694 in front of every arg, not just trailing args. Quote apostrophes.
4695 (_AC_EVAL_ECHO): New macro.
4696 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
4697 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
4699 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
4700 exposed by quoting of eval argument. Put the command on line line
4702 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
4703 (_AC_PATH_X, AC_PATH_X): Quote more safely.
4704 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
4705 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
4706 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
4707 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
4708 Use eval more safely.
4709 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
4710 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
4712 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
4713 lines, exposed by quoting of eval argument.
4715 2006-05-26 Stepan Kasal <kasal@ucw.cz>
4716 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4718 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
4719 initialization of `ac_cv_exeext', do not override it if it was
4720 already set, unless it was set to `no', for compatibility with
4721 Autoconf-2.13, and comment this.
4722 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
4723 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
4724 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
4725 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
4726 Document that this test may be overridden by setting
4729 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4731 Revert these two patches:
4733 2006-04-06 Eric Blake <ebb9@byu.net>
4734 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4735 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4738 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4739 Clean up _AC_COMPILER_EXEEXT* macros.
4740 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4741 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4742 ac_file to the name of the default output file and call
4743 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4744 initial `rm' of the candidate files...
4745 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4746 the same list in subsequent `rm' calls, and for the temporary
4747 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4748 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4749 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4750 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4751 no longer needed) by libtool. Make it a cache check.
4752 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4753 copied here by mistake.
4754 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4755 _AC_COMPILER_EXEEXT.
4756 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
4757 _AC_COMPILER_OBJEXT directly.
4758 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4760 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4762 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
4763 Fix description of how the buggy `sed' works.
4765 2006-05-25 Noah Misch <noah@cs.caltech.edu>
4769 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
4770 ENOLCK. Only mention `make -j' when applicable. Only raise
4771 fatal errors when `make -j' is involved. Improve error message.
4773 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4775 * doc/autoconf.texi (Here-Documents): We now know more about
4776 the variable expansion in here documents bug.
4777 Thanks to Tim Rice and Stepan Kasal.
4779 * doc/autoconf.texi (Making testsuite Scripts): Add an example
4780 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
4782 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4784 * tests/autotest.at (Multiline command from M4 expansion):
4785 No failure to be expected if the shell quotes newlines in
4786 commands in the `set -x' output. Report by Tim Rice.
4789 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4791 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
4792 expansion in the here-documents used by config.status, as that
4793 runs afoul of the Korn shell version M-12/28/93d bug described in
4794 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
4795 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
4796 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
4798 2006-05-23 Jim Meyering <jim@meyering.net>
4800 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
4801 Fix typo introduced with 2006-04-02 change. It reversed the sense
4804 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4806 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
4807 ac_dB slightly, to save bytes in the script.
4808 Max out at 50 lines, rather than 96; this is more likely
4809 (though not guaranteed) to avoid obscure 'sed' failures.
4811 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4813 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
4814 `tr -d -' as bad option argument. Work around this by deleting
4815 an unrelated character.
4816 Report by Tim Rice <tim@multitalents.net>.
4818 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
4819 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4820 Stepan Kasal <kasal@ucw.cz>
4822 * doc/autoconf.texi (Particular Programs): Do not promise that
4823 we always prefer the GNU version of the program, and that we
4824 search according to PATH; both rules can have exceptions.
4825 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
4826 AC_PROG_SED. Move descriptions of limitations
4827 to the Limitations of Usual Tools section.
4828 (Limitations of Usual Tools) <sed>: Mention script length
4829 limitations with Solaris /usr/ucb/sed.
4830 <grep>: Fix wording for empty alternative. Mention that -c and
4831 -l should not be combined, and that -E and -F should not be
4834 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4835 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4837 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
4838 limits in Solaris 8 /usr/ucb/sed by testing a long script.
4840 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4842 * doc/autoconf.texi (Defining Symbols): Literal parameter of
4843 AC_DEFINE is now passed to m4_pattern_allow.
4844 * NEWS: Mention that; likewise for AC_SUBST.
4845 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
4846 the parameter to m4_pattern_allow.
4847 * tests/tools.at: Add a check for that.
4849 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4851 * lib/autoconf/status.m4: Fix typos.
4853 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4855 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
4856 only the files that this macro generates.
4858 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4860 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
4861 the HP-UX sed limitation of 99 commands, labels do not count.
4862 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
4864 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
4866 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4868 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4869 Import the following fix from coreutils:
4871 2006-01-13 Jim Meyering <jim@meyering.net>
4873 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
4874 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
4875 not double-quote uses of that variable, to accommodate the rare
4876 case in which getmntent is available in none of the libraries
4877 checked. This happens at least on FreeBSD 5.0.
4879 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
4881 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
4882 ac_config_guess, ac_config_sub, and ac_configure, since evidently
4883 some other programs unwisely rely on these undocumented vars.
4884 But put in warning comments about them.
4885 Problem reported by Ralf Wildenhues in
4886 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
4887 * NEWS: Document that these variables are intended to go away.
4889 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4891 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,

4895 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
4896 * doc/autoconf.texi (C++ Compiler): Document it.
4897 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
4900 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
4902 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
4903 that caused config.status to generate 100-command sed scripts; the
4904 portable limit is 99.
4906 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4908 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
4909 variable `ac_d' instead of `d' to avoid infringing namespace.
4910 Report by Ralf Menzel.
4912 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
4914 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
4915 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
4916 * tests/tools.at (autoconf: subdirectories): New test, taken from
4917 the corresponding problem report by Ralf Wildenhues in:
4918 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
4920 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
4921 Quote some uses of shell variables if they might suffer unexpected
4922 globbing. This doesn't fix all instances of quoting problems that
4923 I found, just the easy ones that look safe.
4924 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
4925 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
4926 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
4927 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
4928 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

4935 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4937 * bin/autoreconf.in ($help): Reword according to the manual.
4938 Suggested by Olly Betts.
4940 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
4941 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4943 * bin/autoreconf.in: Pass the directory argument to
4944 `require_configure_ac'. Fix comment.
4945 * tests/torture.at (Configuring subdirectories): Expose this.
4946 Reported by Olly Betts.
4948 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4950 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
4951 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
4952 Automake as follows:
4954 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
4955 `$configure_in' instead of `configure.in', to preserve
4956 directory component.
4958 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4960 * config/config.guess, config/config.sub, config/texinfo.tex,
4961 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
4963 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
4965 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
4966 test for C99 conformance; (bool) 0.5 is an integer constant
4967 expression, but (bool) -0.5 is not. Problem reported by Fedor
4968 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
4970 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
4972 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
4973 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
4974 Warn about obsolete install-sh files. Remove stray sentence
4975 fragment and fix cross reference.
4976 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
4977 install -d; this undoes the 2006-05-10 change.
4978 (MKDIR_P): Mark with AN_MAKEVAR.
4979 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
4980 that we don't require $INSTALL to be thread-safe. Move comments
4981 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
4982 of AC_PROG_INSTALL. Output a message saying that we're checking
4983 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
4984 MKDIR_P instead of AC_SUBST.
4985 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
4986 Special magic for MKDIR_P, too.
4987 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
4989 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
4991 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
4993 Sync from Automake, as follows:
4995 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4996 * config/install-sh: Initialize IFS, so field splitting isn't
4998 * config/mkinstalldirs: Likewise.
4999 * config/missing: Remove superfluous quotes. Replace all uses of
5000 `[' by `test', for consistency, and for..
5001 * config/missing (sed_minuso, sed_output): New variables.
5002 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5003 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5004 Fixes `missing' to detect `--output' for help2man. Fixes
5005 PR automake/483. Report by Dennis J. Linse.
5006 (autom4te): Document in `missing --help'.
5008 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5010 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5011 * config/install-sh: Don't use 'path' to talk about file names,
5012 as per GNU coding standards. Close a race condition reported by Ralf
5013 Wildenhues and Stepan Kasal. There is still a race condition
5014 on hosts that predate Posix 1003.1-1992, but we can't help this.
5015 Don't mishandle weird characters like space on pre-Posix hosts.
5016 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5017 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5018 AC_PROG_MKDIR_P from AS_MKDIR_P.
5019 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5020 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5021 earlier editions are not (including Automake 1.8.3).
5022 Do not suggest mkinstalldirs for thread-safety.
5023 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5024 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5025 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5026 presence of special characters and race conditions.
5027 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5028 in Autoconf's name space.
5030 2006-05-10 Bruno Haible <bruno@clisp.org>
5031 and Paul Eggert <eggert@cs.ucla.edu>
5033 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5034 from Automake with minor changes.
5035 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5037 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5039 * config/install-sh: Update to Automake CVS version, as follows:
5040 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5041 * lib/install-sh: Simplify the expr implementation of dirname.
5042 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5043 * lib/install-sh: Handle --, and diagnose unknown options.
5045 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5047 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5048 `./autom4te' to create `./testsuite', since the `all' target
5049 will ensure its presence, but `installcheck' should not create
5050 the uninstalled wrappers.
5052 * tests/torture.at (Unusual Automake input files): Skip if we
5053 detect automake < 1.8.
5055 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5057 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5058 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5059 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5062 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5064 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5065 munge (multiple) white space and other oddities.
5066 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5067 single quotes in variable assignment.
5068 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5069 and similar failures by adding multiple spaces, tabs, and other
5071 Report and different test suggested by Francesco Romani
5072 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5074 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5075 single quotes, we only need to search for single quotes; this
5076 both simplifies the search pattern, and makes us less
5077 susceptible to `echo' variations for arguments not containing
5079 (_AC_ARG_VAR_VALIDATE): Likewise.
5081 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5083 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5084 `$*' and IFS concatenation issue with traditional shells and
5085 bash-2.04. Report by Seanster@Seanster.com.
5087 2006-05-03 Bruno Haible <bruno@clisp.org>
5089 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5090 precisely which Mac OS X versions have the od problem.
5092 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5094 * doc/autoconf.texi: Use @option systematically.

5097 and Bruno Haible <bruno@clisp.org>
5099 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5101 (Integer Overflow): Mention the special case of integer division
5104 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5106 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5107 traditional shells like the Solaris one that do not use the
5108 first IFS character for assembling `$*'.
5109 Prompted by a related report from autoconf_bug@nro.ca.
5111 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5112 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5114 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5115 Mention more problems with the -e option.
5117 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5120 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5122 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5123 in URLs to improve DVI formatted output (requires texinfo 4.6).
5124 (System Services, Systemology, Shellology): Likewise.
5125 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5128 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5130 (Runtime): Fix macro argument names to match description:
5131 `action-if-found' -> `action-if-true' and similarly.
5132 (Obsolete Macros): Likewise.
5133 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5134 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5135 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5137 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5139 * doc/autoconf.texi (Limitations of Make): Clean up markup.

5169 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5170 since as_me isn't set yet.
5172 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5174 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5175 a few minor bugs in this area.
5177 * doc/autoconf.texi (Programming in M4sh): Comment out the
5178 documentation of AS_BASENAME, for now.
5179 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5180 (Limitations of Builtins) <basename>: Do not refer to
5182 * bin/autoconf.as (me): Don't use AS_BASENAME.
5183 (dir): Remove the unused variable.
5184 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5185 AS_DETECT_REQUIRED. All uses changed.

5208 with more accuracy and detail.
5210 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5212 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5213 Archive is not officially `GNU' any more. Update URL.
5214 (Defining Directories): Likewise
5215 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5217 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5219 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5220 newline from the `trap' code to finish `config.log'; the NetBSD
5221 /bin/sh resets the exit status after an empty command, as
5222 documented in doc/autoconf.texi.
5223 Reported by Dalibor Topic <robilad@kaffe.org>.
5225 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5227 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5228 Suggested by Bruno Haible.
5230 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5232 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5233 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5234 Instead, just list the shells that we know work.
5235 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5236 changed. Be more cautious about the _cv_ variable.
5237 * tests/tools.at (Syntax of the shell scripts): Check the
5238 _cv_ variable once, at first, to avoid an internal autoconf error
5239 when sh -n does not work.
5241 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5243 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5245 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5247 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5248 use ">&-" since we're only 99.999% sure that this is portable,
5249 and since the MinGW bug is fixed in a different way.
5250 * lib/autotest/general.m4 (AT_INIT): Likewise.
5252 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5254 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5255 before opening config.log, to avoid hitting a bug on MinGW.
5257 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5259 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5260 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5261 This works around a MinGW bug reported by Eric Paire.
5262 Make sure that all writes to the log file append to it,
5263 rather than possibly losing data.
5264 * lib/autotest/general.m4 (AT_INIT): Likewise.
5266 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5268 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the

5277 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5281 * Makefile.maint (news-date-check): Do not require a leading `*'
5282 before the release date in NEWS.
5284 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5285 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5287 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5288 the instantiated file do not contain the string 'datarootdir'
5289 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5290 @mandir@, replace the reference '${datarootdir}' by the value.
5291 * tests/torture.at (datarootdir workaround): New test.
5292 * NEWS: Advertise this temporary fixup.
5293 Based on a patch by Bruno Haible, reported and analyzed by
5294 Paul Eggert and Noah Misch.
5296 2006-04-12 Eric Blake <ebb9@byu.net>
5298 * tests/autotest.at (Debugging a failed test): Fix comment.
5300 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5302 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5303 all the changes since 2006-04-07.
5305 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5307 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5308 succeeded, but `ln -s file dir' failed, take care to remove the
5309 leftover target before the next test, to prevent its spurious
5310 failure; also make sure `ln file dir' works before selecting it.
5311 Thanks to Keith Marshall for pointing this out.
5314 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5315 assignments in `at_debug_args', so that we put them correctly
5316 in the `run' script.
5317 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5318 Reported by Eric Blake.
5320 2006-04-11 Eric Blake <ebb9@byu.net>
5322 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5323 top-level tests after micro-suite has been run. Used in...
5324 (Debugging a successful test, Debugging script and environment),
5325 (Debugging a failed test): ...these new tests. The first of these
5327 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5328 macro, split out from...
5329 (AT_INIT): ...here, so that using -d also generates a run script.
5330 Document that -d inhibits top-level logging.
5331 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5332 inhibits top-level logging; debug scripts are created.
5334 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5336 * tests/autotest.at (Empty test, Empty check): New test to check it.
5338 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5341 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5343 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5344 the files if a problem appears. Make the empty *.at files
5345 read-only, too. Proposed by Ralf Wildenhues.
5347 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5349 * config/Makefile.am: Add comment to force updated Makefile.in.
5351 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5352 space only patch to this file, this patch causes the Makefile.in
5353 files that include freeze.mk to be updated, and thus have a
5354 newer time stamp again, which in turn makes a pristine CVS
5355 checkout have correct time stamps.
5357 * Makefile.maint (cvs-sv): New macro, to be used..
5358 (config.guess-url_prefix, config.sub-url_prefix)
5359 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5360 point to CVS text checkout of Gnulib files.
5361 (copyright-check): Bump current year.
5362 (announcement): Do not hard-wire `./announce-gen'.
5363 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5365 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5367 (wget_files): Update config.guess, config.sub, texinfo.tex by
5368 `wget-update', now that their URLs work again.
5370 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5372 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5373 Problem noted by Paul D. Smith.
5375 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5377 * doc/autoconf.texi: Remove unused words from word list.
5378 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5379 .x-sc_trailing_space: New files.
5381 * doc/standards.texi: Sync from gnulib.
5383 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5384 `LIBOBJDIR' as experimental.
5386 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5387 with a target directory; it's internally implemented as `cp'
5388 anyway, but since Autoconf advertises the possibility to use
5389 a target directory when LN_S is `ln -s', we need to find out.
5390 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5391 analyzed by Keith Marshall <keith.marshall@total.com>.
5395 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5397 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5398 confdefs.h as-is. In general, if it has backslash-newline or the
5399 like, then it doesn't work either to sort or to remove empty
5402 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5404 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5406 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5408 * lib/autom4te.in (Automake-preselections): Preselect
5411 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5413 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5414 apostrophe within a single-quoted string, as this is the usual
5415 tradition and is easier to read than '"'"'. Don't rely on the
5416 shell treating "$/" like '$/'. Use a more-consistent indenting
5419 2006-04-09 Eric Blake <ebb9@byu.net>
5421 * tests/autotest.at (Backquote command substitution),
5422 (Multiline backquote command substitution): Remove mistaken
5423 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5425 (Parenthetical command substitution, Multiline parenthetical
5426 command substitution): here.
5428 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

5461 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
5462 (C Compiler): Move AC_C_LONG_DOUBLE to ...
5463 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
5464 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.

5492 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
5493 of the warning introduced by the 2001-08-28 change.

5503 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5505 Revert the patch from 2006-04-01 and only improve
5506 _AS_DETECT_BETTER_SHELL:
5508 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
5509 skip nonexistent directories.
5510 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
5511 only shell candidates which exist.
5512 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
5513 * lib/autotest/general.m4 (AT_INIT): No need to give three
5514 parameters to _AS_PATH_WALK.
5516 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
5517 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5519 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
5520 distinguish m4sugar macros.
5521 * tests/tools.at (autoupdating with aclocal and m4_include):
5522 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
5523 test case by Noah Misch <noah@cs.caltech.edu>.
5525 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5527 Revert my change from 2006-03-17, in other words:
5528 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
5530 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
5531 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
5534 2006-04-07 Eric Blake <ebb9@byu.net>
5536 * doc/autoconf.texi (Programming in M4sh): Document that
5537 AS_MKDIR_P exits the script on failure.
5538 * lib/autotest/general.m4: Remove redundant AS_ERROR.
5540 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5542 * config/elisp-comp, config/install-sh, config/mdate-sh,
5543 config/missing, config/mkinstalldirs: Sync from Automake.

5557 Eric Blake <ebb9@byu.net>,
5558 Paul Eggert <eggert@cs.ucla.edu>,
5559 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5561 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
5562 whether `set' quotes correctly: redirect stderr of the tested
5563 `set', and use a subshell, for Ultrix; use `sed' instead of
5564 `grep' for zsh `set' which may write binary output; match only
5565 at the beginning of a line, to avoid false positives.
5566 In order to avoid false positives by unrelated variables with
5567 multiline content, put the dump algorithm in a subshell and
5568 unset all variables containing newlines (except some which are
5569 special to the shell). Warn about cache variables that are
5572 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5574 * config/config.guess, config/config.sub, config/texinfo.tex:
5577 * tests/mktests.sh: Reword comments.

5615 ac_config_<foo>s again, sometimes normalized, sometimes not.
5616 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
5617 (AC_CONFIG_COMMANDS): Do not do so here.
5618 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
5619 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
5620 2005-07-25 rewrite. Noticed by Noah Misch.
5622 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
5623 _AC_PRESERVE_HELP_ORDER, ...
5624 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
5626 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
5627 inside m4_expand_once; it is redundant.
5629 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
5630 for --help from Cygnus `configure.'
5632 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

5645 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
5646 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
5647 * doc/autoconf.texi (Help Formatting): New node.
5648 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
5650 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5652 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
5653 lib/autoconf/specific.m4, lib/autoconf/status.m4,
5654 lib/autoconf/types.m4, lib/autotest/general.m4,
5655 tests/mktests.sh, tests/torture.at: White space cleanup:
5656 remove some SPACE before TAB, or add quoting ('' or @&t@).
5658 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
5660 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
5662 2006-04-05 Eric Blake <ebb9@byu.net>
5664 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
5665 empty test suite works.
5666 * tests/autotest.at (Empty test suite): Remove xfail.

5674 normalizing it, consistent it with previous releases.
5675 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
5677 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
5679 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
5680 Use simplified args that Eric Blake originally suggested.
5682 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
5684 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
5685 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
5686 Use 'comm' rather than N instances of grep; this also fixes a bug
5687 whereby substrings were incorrectly matched, causing us to not
5688 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
5689 (exclude_list): Exclude empty macros.
5690 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

5702 a subdirectory subject to Cygnus `configure'.
5703 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
5705 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
5706 report request when we have no AC_PACKAGE_BUGREPORT.
5708 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5712 * tests/mktests.sh: Update copyright year in the header of the
5715 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
5716 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
5717 typedef'ed restricted pointer, to catch a compiler bug on
5718 HP-UX 11.x, and fix warnings so it passes with -Werror.

5730 2006-04-03 Noah Misch <noah@cs.caltech.edu>
5732 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.
5734 2006-04-03 Eric Blake <ebb9@byu.net>
5736 * THANKS: Add myself.
5738 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5740 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
5741 to log, point to testsuite output tree.
5743 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
5745 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.

6562 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
6563 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
6564 by the function rather than ignoring it.
6565 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
6566 comparing its address. Intel's interprocedural optimization was
6567 outsmarting the old heuristic. Problem reported by

6585 Stepan Kasal <kasal@ucw.cz>
6587 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
6588 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
6589 make its content writable before removing it. Remove an errorneous
6590 comment from the end, where the logs of the failed tests are copied

6616 suggested by Ben Elliston. Handle weird characters correctly.
6618 2005-09-06 Stepan Kasal <kasal@ucw.cz>
6620 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
6621 calls, so that the final expansion of this macro is shorter.
6622 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
6623 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
6624 the cleanup there. Use AS_VAR_* macros, to be more general.
6625 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
6627 * lib/autoconf/general.m4: Use AS_IF where appropriate.
6629 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

6649 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
6650 in the example. Reported by Bruno Haible.
6651 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
6652 "if $undefined_var;" succeeds with my shell.
6654 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
6655 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
6656 but change the m4_divert_text to m4_divert_once.
6658 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
6660 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):

6666 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
6667 some evil values and relying on the fact that $* concatenates the
6668 parameters by the first character from IFS.

6674 first header appears, define AH_HEADER.
6675 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
6676 Update limitations about when to call AC_CONFIG_HEADERS.
6677 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
6678 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
6679 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
6680 ``Configuration Actions''; fix their index entries.
6682 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
6683 options correctly. Process N-M as M-N if M is smaller than N.
6684 Process ranges correctly so that N-N will run only N.
6685 Sort and uniquify the tests that will be run. If there is more
6686 than one test, reinsert the banners for the tests.
6687 * tests/autotest.at (Keywords): Unmark XFAIL.
6689 2005-08-23 Stepan Kasal <kasal@ucw.cz>

6692 before passing the macro name to AH_TEMPLATE.
6694 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
6695 now opens log after option processing; in particular, --version
6696 and --help do not touch config.log.

6713 Prepend to LIBS, not append, in examples.
6715 2005-08-16 Stepan Kasal <kasal@ucw.cz>
6717 When building in place, set srcdir="."; suggested by Tim Van Holder.
6719 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
6720 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
6721 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
6722 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
6723 does not mean "no --srcdir option".
6725 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6727 * tests/autoscan.at (autoscan): New file.
6728 * tests/suite.at: Use it.

6736 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,

6752 * Makefile.maint: Update from Bison.
6754 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
6755 "<tab>" in comment, so that the point is understandable.
6757 2005-07-25 Stepan Kasal <kasal@ucw.cz>
6759 Rewrite substantial part of lib/autoconf/status.m4.
6760 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
6761 and CONFIG_COMMANDS are not processed in four separate loops.
6762 Instead, there is one main loop. This alows that the common code
6763 is expanded only once, thus config.status (and configure) is smaller.
6765 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
6766 the AC_LIST_FILES and cousins macros are no longer used.
6768 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
6769 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
6770 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
6771 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
6772 contain the initialization, nor the for loop, nor the associated
6773 commands; all these go to ...
6774 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
6775 _AC_OUTPUT_CONFIG_STATUS.
6776 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
6777 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
6778 (_AC_OUTPUT_FILE): The creation of the sed script ...
6779 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
6780 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
6781 _AC_OUTPUT_MAIN_LOOP.
6782 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
6783 _AC_CONFIG_COMMANDS): Use ...
6784 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
6785 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
6786 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
6787 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
6788 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
6789 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
6791 (_AC_CONFIG_UNIQUE): Update.
6792 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
6793 Replaced by this ...
6794 (_AC_LIST_TAGS): ... new common macro.
6795 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
6796 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
6797 (_AC_LIST_TAG_COMMANDS): ... new common macro.
6798 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
6799 this didn't belong to the `config commands' section.
6800 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
6801 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
6802 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
6803 to the `config commands' section either.
6804 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
6805 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
6807 ... and many changes to the comments nearby.
6809 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
6810 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
6811 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6812 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
6813 (#define header templates): The comment at the top of the generated
6814 header now includes the name(s) of the source file(s).
6816 Several unrelated small changes:
6818 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
6819 parameter to AC_DIAGNOSE.
6820 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
6821 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
6822 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
6823 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
6825 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
6826 in AC_OUTPUT doesn't double-quote it either.
6827 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
6830 2005-07-10 Stepan Kasal <kasal@ucw.cz>
6832 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
6833 versions of Portland Group compiler produce single- and double-quoted
6834 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
6835 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
6837 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
6839 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
6840 This is a corrected version of yesterday's patch.
6842 2005-07-07 Stepan Kasal <kasal@ucw.cz>
6844 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full

6848 ac_cv_build_alias to ac_build_alias.
6849 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
6851 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
6852 change eliminates it. Problem reported by Alexandre Duret-Lutz.
6853 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
6854 (AC_ARG_VAR): ... here.
6855 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
6858 Keep a list of all precious variables and process them with one simple
6859 for loop, instead of expanding all commands, or, OTOH, complicated
6860 processing of output of "set".
6861 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
6862 variable names in new macro...
6863 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
6864 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
6865 a loop to assign all ac_env_* and ac_cv_env_* variables.
6866 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
6868 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
6869 its value to shell variable ac_precious_vars and call
6870 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
6871 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
6872 _AC_ARG_VAR_VALIDATE.
6874 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

6905 at_top_builddir, for compatibility with older autotest.
6906 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
6907 is not set, use at_top_builddir, for compatibility with older
6908 versions of autoconf.
6910 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
6912 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
6913 Problem reported by Patrick Welche.
6915 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
6917 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
6918 sed substitution command, so that we allow | in program prefixes
6919 and program suffixes. (& is a problem anyway; we're not fixing
6921 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
6922 configure_input, top_builddir, srcdir, etc.
6923 * lib/autotest/general.m4 (AT_INIT): Likewise, for
6924 PATH_SEPARATOR in AUTOTEST_PATH.
6926 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

6934 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
6935 directories with weird names. Apparently some people like living
6936 on the edge. However, improve the test that "pwd" actually does
6937 report a name for the working directory.

6957 document to output the default config_* lists to config.status.
6958 Don't recognize option --file, if the functionality is not there.
6959 Likewise for --header; moreover, recognize --he and --h as shortcuts
6960 for --help in that case.
6962 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
6963 matches the order of execution. No code changed.

6987 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
6988 the directory specific variables; but don't call it for configure_input.
6990 2005-06-28 Derek Price <derek@ximbiot.com>
6992 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
6995 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
6997 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

6999 due to limitations in Make syntax. Problem reported by Alexandre
7001 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

7016 variable into diagnostic. Make the diagnostic an error, not a warning,
7017 because we really don't support spaces and suchlike in dir names.
7018 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7019 Don't worry about backslashes in srcdir; it can't happen now.

7063 * doc/autoconf.texi:
7064 Don't mention Solaris versions so much, if a
7065 problem is common to all extant versions of Solaris. Say "SunOS
7066 4" instead of "SunOS" for SunOS 4.
7067 (awk): Mention more of the limitations of traditional Awk.
7068 (cat): Don't talk about cat -v.

7112 Problem reported by Ralf Menzel.
7114 2005-06-08 Derek Price <derek@ximbiot.com>
7116 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7117 renaming them since they are about to be redefined anyhow.
7119 2005-06-08 Derek Price <derek@ximbiot.com>
7121 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7122 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7123 Move m4_undefine to alphabetical order.

7131 Clarify explanation of HP compiler bug.
7132 Redo example output tp match current CVS snapshot.
7133 Use @example.org in email addresses when the examples
7134 might get inadvertently cut-and-pasted into user code.
7135 Remove example of autom4te usage that doesn't seem to work now.
7136 Use modern AC_INIT (except when the example is meant to be

7151 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7152 Tru64 ksh pattern matching bug. Reported against Libtool by
7153 Albert Chin <libtool@mlists.thewrittenword.com> and
7154 Nicolas Joly <njoly@pasteur.fr>.

7158 m4_cdr of one-member list was [[]] (one-member list containing an
7159 empty string) instead of [] (an empty list. Callers were skewed to
7160 match this misbehaviour. As a consequence of this:
7161 - m4_foreach([x], [], [foo]) expanded to `foo', while
7162 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7163 This bug has been fixed:
7165 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7166 expand to an empty string; print error msg if called without
7168 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7169 misbehaviour; handle [] and [[]] correctly.
7171 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7173 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
7174 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
7175 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
7177 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7179 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7180 swallow records with more than 99 fields.
7181 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7182 parse the long line.
7184 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7186 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7187 swallow literals longer than 399. Reported by Ralf Wildenhues.
7188 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
7189 to workaround this limitation.
7191 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
7193 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7194 to gfortran, and make these the first two compiler names
7195 checked (following the general autoconf preference for gcc).
7197 2005-06-03 Stepan Kasal <kasal@ucw.cz>
7199 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7200 (DISTCLEANFILES): Remove $(check_SCRIPTS).
7201 (testsuite): Make sure autotest.m4f is up-to-date before using it.
7203 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
7205 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7206 expression of unbounded size when processing the --list
7207 option. This runs afoul of a limit of 399 bytes per regular
7208 expression on AIX. Problem reported by Ralf Wildenhues.
7210 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
7212 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
7213 * doc/autoconf.texi (Particular Headers): Reword example
7214 for multiline stdbool replacement.
7215 (Setting Output Variables): Reword text a bit. Don't
7216 give all the details about |#_!!_#|.
7217 Reword description of line replacement.
7219 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7221 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7222 now contain newlines, and substituted files must be referenced on
7223 a line alone; the sed scripts to substitute them are now very
7225 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
7226 commands can be put in a sed script portably.
7227 * doc/autoconf.texi (Setting Output Variables): Document above
7228 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
7229 use of multiline substitution.
7230 * tests/torture.at: No longer expect substitution of newline to fail.
7232 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
7234 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
7235 From Ralf Menzel (trivial change).
7237 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
7239 * tests/local.at: Don't attempt to check for negated character
7240 classes in shell scripts. The test was too brittle.
7242 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7244 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
7245 * doc/autoconf.texi (Limitations of Builtins): Document this
7248 2005-05-24 Stepan Kasal <kasal@ucw.cz>
7250 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
7251 common code; used in many places in the tree.
7252 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
7253 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
7255 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
7257 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
7258 messages when ac_unique_file is not found.
7259 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7260 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
7261 commands, for consistency with AC_MSG_ERROR and such.
7263 * bin/autoconf.as: Make more use of "shift 2" in option processing.
7265 * bin/Makefile.am: Merge the two rules for creating scripts.
7267 2005-05-23 Stepan Kasal <kasal@ucw.cz>
7269 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
7270 obsolete; it was never documented.
7271 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
7273 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7275 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
7276 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7277 (ac_top_builddir): ... this ...
7278 (ac_top_build_prefix): ... to this; the old name is also kept, for
7279 backward compatibility.
7280 (ac_top_builddir_sub): New variable, without the trailing slash,
7282 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
7283 * doc/autoconf.texi (Configuration Actions): Rename
7284 ac_top_builddir to ac_top_build_prefix.
7285 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
7286 at_top_builddir to at_top_build_prefix.
7287 * lib/autotest/general.m4 (AT_INIT): Likewise.
7289 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7291 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
7294 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7296 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7297 argument to m4_foreach. I guess it was necessary in the past,
7298 but I think it's a no-op now.
7300 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7302 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7303 ``cat <<_ACEOF'' commands to one.
7304 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
7305 * lib/autoconf/status.m4: On various places, use expr instead of
7307 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
7308 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
7309 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7311 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
7312 the wrong patterns between ``case'' and ``esac.'' The previous
7313 code had false positives.
7315 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
7317 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

7360 2005-05-13 Stepan Kasal <kasal@ucw.cz>
7362 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
7364 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
7365 enough arguments, similarly as in m4_bpatsubsts.
7367 2005-05-12 Stepan Kasal <kasal@ucw.cz>
7369 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
7372 2005-05-11 Stepan Kasal <kasal@ucw.cz>
7374 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
7375 for absolute directory names in one loop.
7376 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
7377 abbreviations of --version and --debug.
7379 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
7381 * doc/autoconf.texi (Autoconf Language): Be more precise about
7382 quoting rules. Problems noted by Stepan Kasal.
7383 Also, throughout this document, be more careful about white space.
7384 "blank", "white space", and "space" all have different meanings
7385 and we should be careful to say what we mean.
7387 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
7389 Fix C++ related problems reported by Werner Lemberg.
7390 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
7391 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
7392 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
7393 avoid problems with C++ and throw.
7394 * tests/compile.at: .cpp, not .cc.
7396 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
7398 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7400 * doc/autoconf.texi (Generic Functions): Typos.
7402 2005-05-02 Gary V. Vaughan <gary@gnu.org>
7404 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
7405 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
7406 set by latest automake.
7408 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7410 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
7411 outputs 0 on GNU/Linux these days.
7413 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
7415 * doc/autoconf.texi (Autoconf Language): Add more description
7416 about quoting heuristics.
7417 (Limitations of Builtins): Describe "set -" problems.
7419 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7421 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
7424 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
7425 by AC_DEFINE; it was a mistake.
7426 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
7428 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7430 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7432 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7434 * doc/autoconf.texi (External Software): Quadrigraphs are not
7435 processed correctly in AS_HELP_STRING; avoid this in the examples.
7436 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7437 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7438 comment and reduce m4_default([foo], []) to [foo].
7439 (m4_strip): Update the explanation.
7441 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7443 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7444 Remove core.conftest.* too; it's generated by Tru64 5.1.
7445 Problem reported by Jennis Pruett.
7446 * lib/autoconf/functions.m4
7447 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7448 Don't bother to remove core files; AC_RUN_IFELSE should do that
7451 2005-04-19 Stepan Kasal <kasal@ucw.cz>
7453 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
7455 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
7457 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
7458 Report from Horst Wente.
7460 2005-04-15 Stepan Kasal <kasal@ucw.cz>
7462 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
7465 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
7467 * doc/autoconf.texi (External Software, Package Options): Add
7468 examples showing how to implement --with-* and --enable-* options.
7470 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
7472 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
7473 as well as configure.in. Problem reported by Gregorio Guidi.
7475 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
7477 * doc/autoconf.texi (Particular Functions): Use gnulib's current
7478 pattern for alloca snippet.
7480 2005-04-04 Stepan Kasal <kasal@ucw.cz>
7482 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

7488 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
7490 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
7491 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
7493 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7495 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
7496 Merge `-z option' as well for the benefit of Solaris link flags. Pass
7497 whole-archive (-zallextract, -zdefaultextract) options in the hope of
7498 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
7499 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
7501 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
7503 * NEWS: The configure command now warns you if you attempt to use
7504 a directory whose name contains a special character like space,
7506 * doc/autoconf.texi (Installation Directory Variables): Allow
7507 "," in file names. Do not use \@; it's not a portable regexp.
7508 * bin/Makefile.am (edit): Likewise.
7509 * lib/Makefile.am (edit): Likewise.
7510 * tests/Makefile.am (edit): Likewise.
7511 * tests/semantics.at: Likewise.
7512 * tests/torture.at: Likewise.
7513 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
7514 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
7515 * doc/autoconf.texi (File System Conventions): Warn about
7516 unportable file names.
7517 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
7519 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
7520 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
7521 ac_pwd, and quote srcdir.
7522 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
7524 * doc/autoconf.texi: Fix some systematic formatting problems.
7525 ".)" needs a following @: if not at the end of a sentence, and
7526 similarly for "!)". "etc." should be preceded by a comma.
7527 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
7529 2005-03-22 Bruno Haible <bruno@clisp.org>
7531 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
7532 argument is often called 'build-aux'.
7534 2005-03-07 Stepan Kasal <kasal@ucw.cz>
7536 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
7537 macro AC_TRY_LINK is obsolete.
7538 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
7541 2005-02-24 Stepan Kasal <kasal@ucw.cz>
7543 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
7544 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
7545 from a Common Lisp's `cl'.
7546 (AC_PROG_CXX): Behave according to the documentation: don't
7547 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
7548 make the variable CCC precious; use `cl.exe', not `cl'.
7550 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7551 Alexandre Duret-Lutz <adl@gnu.org>
7553 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
7554 /dev/null, as "configure" shouldn't read stdin, and this insulates
7555 us from problems (e.g., when testing for "cl"). Also, do this
7556 redirection before invoking "hostname" or "uname", and keep the
7557 original input stream available via...
7558 (AS_ORIGINAL_STDIN_FD): ... this new macro.
7559 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
7560 bother with "</dev/null" since it's now done at the top of
7562 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
7563 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7564 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7565 * doc/autoconf.texi (File Descriptor Macros): New section.
7566 (Printing Messages): Mention it.
7567 * tests/base.at (Input/Output): New test.
7569 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7571 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
7572 newline if neither \c nor -n work, as that would output two
7573 newlines. Prefer -n to \c. Reported by Stepan Kasal.
7575 2005-02-12 Stepan Kasal <kasal@ucw.cz>
7577 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
7578 This causes that any required macros inside will get before the if.
7579 * doc/autoconf.texi (autom4te.cache): A typo.
7581 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
7583 Undo previous change, except keep the change to
7584 lib/autoconf/programs.m4 that replaced grep with shell
7585 pattern-matching. This is because net-snmp configure reads stdin.
7586 Reported by Noah Misch.
7588 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
7590 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
7591 from /dev/null, as "configure" shouldn't read stdin, and this
7592 insulates us from problems (e.g., when testing for "cl").
7593 Suggested by Alexandre Duret-Lutz. Also, do this redirection
7594 before invoking "hostname" or "uname".
7595 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7596 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
7597 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
7598 "</dev/null" since it's now done at the top of 'configure'.
7599 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7600 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7601 Also, replace grep with shell pattern-matching, to save a process.
7603 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
7605 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,

7706 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

7709 2047-byte limit on line length of portable text files.
7710 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
7711 Use newline as a separator, not space.

7769 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
7770 Update the long comment explaining it.
7772 m4_require no longer writes an ``is required by'' line to the
7773 execution stack. It contains only one bit of non-redundant
7774 information: that the macro was required, not called. And even
7775 this bit is useless in most situations: have you ever met a macro
7776 which both calls and requires the same macro?
7778 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
7779 (_m4_defun_pro_outer): ... only via this macro, for the outermost

7826 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
7827 Warn about newline stripping in `` and $(). Update Solaris
7829 (Limitations of Builtins): Use expr "X...", not expr "x...", as
7830 X insulates us from future changes to Posix.
7831 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline

7858 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

7884 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
7885 stored in _m4_divert_diversion or _m4_divert_dump.
7886 (m4_divert_pop): When the parameter is given, compare the symbolic
7887 name with the last diversion pushed on the stack. Previously, the
7888 current diversion was compared with the numeric value of the
7889 diversion given as the parameter.
7890 (m4_require): If the macro hasn't been expanded yet, call ...
7891 (_m4_require_call): this new macro.

8170 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
8172 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
8173 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
8174 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
8175 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.

8196 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
8198 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8199 "char c = '\200';" rather than "char c = 0x80;" as the
8200 latter doesn't conform to the strict C standard due to
8201 overflow on signed char hosts.
8203 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
8204 to -qlanglvl=ansi. We don't want to disable extensions.
8206 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
8208 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

8260 simplify the examples and improve their quoting.
8262 2004-11-13 Stepan Kasal <kasal@ucw.cz>
8264 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
8265 the $1_found variable, don't test whether the file is executable;

8317 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
8318 "/usr/include", clear ac_x_includes instead of leaving it as "no"
8319 (trivial change). Problem and patch reported by Andrew Church in:

8349 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
8350 texinfo.tex for now (done by hand now).
8351 * Makefile.maint (wget_files, cvs_files):
8352 Remove ansi2knr.c; nobody uses it.
8353 (ansi2knr.c-url_prefix): Remove.
8354 (cvs-update): Fix test for failure. I don't know why it ever
8357 * doc/autoconf.texi: Update URLs, some of which went stale.
8358 Use @uref rather than @href.
8360 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
8361 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
8363 * config/config.guess, config/config.sub, config/elisp-comp,
8364 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
8365 doc/fdl.texi, doc/standards.texi: Sync with master copy.

8373 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
8374 tests/tools.at, tests/torture.at:
8375 Use "file name" rather than "filename" or "path",
8376 to be consistent with the terminology of the GNU coding standards.
8378 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
8380 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),

8385 More fixes to support spaces in the name of the build directory.
8386 This isn't a complete fix but it's an improvement.
8388 * bin/autoconf.as (autom4te_options): New var.
8389 Use it instead of appending to AUTOM4TE, so that we can allow
8390 spaces in the build directory's absolute name.
8391 * bin/autoheader.in ($autoconf): Allow spaces in file names.
8392 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

8405 * doc/autoconf.texi (Function Portability): Document isinf and
8406 and isnan. From a suggestion by Kevin Ryde.
8408 * lib/Autom4te/General.pm (END): Return correct exit status even
8409 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
8411 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
8413 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
8414 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
8415 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.

8422 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
8423 * lib/autom4te.in (Automake-preselections): Preselect
8424 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8426 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8428 * lib/autom4te.in (Automake-preselections): Preselect
8429 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
8432 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
8434 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for

8441 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
8442 with pdksh, too. Problem reported by Patrick Welche via
8444 * doc/autoconf.texi (Shellology): Note that set -o posix is
8445 useful for pkdsh, too.
8447 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
8449 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8450 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8451 Don't fail if ENV or BASH_ENV is readonly.
8452 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
8453 etc. are read only. Problem reported by Ludovic Courtes.
8455 2004-06-23 Noah Misch <noah@cs.caltech.edu>
8457 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is

8461 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
8463 * doc/autoconf.texi (File System Conventions): Warn about
8464 names like "aux". Problem reported by Eric Blake.
8466 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
8467 by zero instead of array size, so that we can use any arithmetic
8468 constant expression (instead of requiring an integer constant
8469 expression). This allows us to test expressions like DBL_MAX <
8470 LDBL_MAX, which didn't conform to the C standard using the old
8472 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
8473 now that we can do floating-point tests at compile time.
8475 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8477 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8478 and LDBL_EPSILON, as the resulting expression isn't an
8479 integer constant expression and violates the C standard.
8480 Problem reported by Nelson H. F. Beebe. Also, check
8481 for "L" suffix, and check that long double doesn't have
8482 worse range or precision than double, that mixed-mode
8483 arithmetic doesn't generate a diagnostic, that double
8484 constants fit in long double.
8486 2004-06-03 Kevin Ryde <user42@zip.com.au>
8488 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
8489 malloc(0) and realloc(NULL,size).
8491 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
8494 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
8496 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
8497 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
8500 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8502 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND

8513 change). Patch reported by Ralf Wildenhues in
8514 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
8516 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8517 function F exists if the compiler and linker let you compile an
8518 expression like (F != 0). Recent versions of GCC optimize away
8519 the reference to F in that case, since every function address must
8520 be nonzero, so the link succeeds even if F does not exist.
8521 Problem reported by Manu in
8522 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
8524 * doc/autoconf.texi (Systemology): Standardize on the spelling of
8525 "Unix". Many uses changed.

8537 referencing AC_FUNC_STRERROR_R.
8539 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
8540 note pessimistic assumption when cross compiling.
8542 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
8544 * doc/autoconf.texi (Limitations of Make): Note that BSD make
8545 (until 2004) invoked subcommands with sh -e, contra POSIX.
8546 Reported by Kevin Ryde.
8548 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
8550 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
8551 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
8552 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
8553 `test -f " /usr/bin/grep"', which _always_ failed.
8554 (AC_PROG_SED): Ditto bogus PATH fix.
8555 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
8556 requires that grep correctly supports _multiple_ `-e' options, rather
8557 than stating only that grep should accept `-e'.
8559 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
8561 Port to C99, which requires that 'exit' be declared.
8563 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
8564 to ensure that stdlib.h is included.
8565 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
8566 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
8567 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
8568 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
8569 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
8570 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
8571 when using 'exit' in a test; C99 requires that 'exit' be declared.
8573 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
8575 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
8576 now prefers 'grep' implementations that accept -e.
8577 (Limitations of Usual Tools): Describe problems of traditional
8578 egrep and fgrep with long input lines, and of traditional grep
8580 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
8581 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
8582 All callers changed. Append /usr/xpg4/bin to the PATH, for
8584 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
8585 the user with complaints about multiple -e options.
8586 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
8587 Define it with AC_PROG_GREP.
8588 * configure.ac (AC_PROG_GREP): Add.
8589 * lib/freeze.mk (GREP): New macro.
8591 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
8593 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
8594 a possible candidate only after all others fail, rather than
8595 consulting it first. This improves backward compatibility by
8596 better reflecting the way shell selection occurred in previous
8597 versions of Autoconf, and should help to avoid triggering latent
8598 problems in other packages, such as the one in Automake where zsh
8599 is not handled robustly:
8600 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
8601 Although it is not Autoconf's responsibility to work around
8602 problems in Automake, it nevertheless makes sense to avoid
8603 introducing unnecessary incompatibilites.
8605 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
8606 Gary V. Vaughan <gary@gnu.org>
8608 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess

8610 ac_path_TOOL_found flag.
8611 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
8612 nested we are in this macro. Break out of all 3 nested loops if
8613 ac_path_TOOL_found is set.
8615 2004-04-21 Gary V. Vaughan <gary@gnu.org>
8617 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
8618 of the _AS_PATH_WALK loop too if GNU flavor is found.
8620 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
8622 * doc/autoconf.texi (Limitations of Make): Update documentation
8623 for `$<'. New entry `Long lines', based on a report from Simon
8624 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
8625 paragraph about DJGPP, based on a mail from Richard Dawe.
8627 2004-04-20 Paul Eggert <eggert@twinsun.com>
8629 * tests/c.at (C keywords): Don't assume that GCC supports
8630 "restrict" and "inline", as sufficiently-old GCC versions do not
8631 (also, GCC configured to be in pedantic C89 mode does not).
8632 Problem reported by Sumit Pandya in:
8633 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
8635 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
8636 consider -g to work if it generates warnings when plain compiles
8637 don't. Problem reported by Braden McDaniel in:
8638 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html

8644 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
8645 linker output files before linking, to work around IRIX 6 linker bug.
8646 Problem reported by Rainer Orth in:
8647 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
8649 2004-04-20 Gary V. Vaughan <gary@gnu.org>
8651 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
8652 best tool so far counter rely on the tool path variable name to
8653 avoid checks for one tool being affected by the results of running
8654 the length check on a previous tool.
8656 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
8657 match expression argument, as different greps have different
8658 regular expression flavours.
8659 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
8661 (AC_PROG_EGREP): Pass 'EGREP$'.
8662 (AC_PROG_GREP): Pass 'GREP$'.
8664 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
8666 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
8667 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.

8671 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
8672 Types, Specific Compiler Characteristics, System Services,
8673 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
8674 etc. consistently instead of 'long', 'short', 'unsigned' etc.
8675 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.

8687 2004-03-28 Paul Eggert <eggert@twinsun.com>
8689 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
8690 now defines HAVE_DECL_TZNAME if it is declared, when
8691 HAVE_STRUCT_TM_TM_ZONE is not defined.
8692 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
8693 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

8704 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
8705 Fortran compiler is ifort, also added pghpf; thanks to Nelson
8706 H. F. Beebe for the bug report.

8762 * bin/Makefile.am (edit): Don't use $< in a context where
8763 POSIX doesn't require support for it. Use $@.in instead.
8764 Problem reported by Anthony N. Frasso in
8765 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

8788 (MAINTAINERCLEANFILES): Split into pieces,
8789 one per related section. Add $(srcdir)/wrapper.in.
8791 2004-02-09 Paul Eggert <eggert@twinsun.com>

8794 AC_SUBST provides no portable way to escape literal newlines.
8796 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
8797 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
8798 Darwin uses -lcrt2.o and there's little point to cataloging all
8799 the system variants. Partial fix reported by Andreas Waechter in:

8924 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
8925 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
8926 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
8927 not <inttypes.h>. Problem reported by Tim Mooney in

8929 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
8932 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
8933 otherwise "make check" fails because it forbids cmp (I guess
8934 because cmp treats files as binary on DOS-like systems).

8937 have changed in 2004.
8939 2004-01-23 Gary V. Vaughan <gary@gnu.org>

8947 2004-01-15 Paul Eggert <eggert@twinsun.com>
8949 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
8950 -std1 disables some useful extensions on Tru64. Problem reported

8957 AS_MKDIR_P succeeds if the destination is a symbolic link
8958 to an existing directory.
8959 (Limitations of Usual Tools): Note that mkdir -p might not
8960 succeed on symlinks to directories.

9496 The test suite are sometimes assigning timings incorrectly.
9497 Reported by Henk Krus.
9498 Diagnosed by Nicolas Joly.
9500 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
9502 Instead of making AT_help a sequence of assignments to grow
9503 $at_help_all, just make AT_help_all be the growing contents of
9504 $at_help_all, and make a single assignment in...
9506 (at_times_skip): Flip the meaning and rename as...
9508 (AT_INIT): When summarizing the test that ran, remove
9509 $at_times_file after use, and check it is present before trying to

9516 * bin/Makefile.am (edit): Handle '@configure_input@'.
9517 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
9518 (ifnames): chmod -w.
9519 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
9520 executables, not bin/ executables! Otherwise all the magic needed
9521 to find non installed files is turned off. This caused a failure
9522 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
9523 as found in its environment (sent by tests/autoreconf): pointing
9524 to bin/autom4te that could not find its files.
9525 * tests/mktests.sh: Force the replacement of generated files, for
9526 the sake of "mv" program that are interactive when overwriting a
9528 * config/install-sh: Upgrade from CVS Automake.

9535 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
9536 Paul Eggert <eggert@twinsun.com>
9538 Trivial change to support GCC's configuration procedure.
9539 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
9540 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
9541 about inconsistency if the preprocessor is set to give errors for

9569 From Peter Hendrickson.
9571 2003-09-10 Akim Demaille <akim@epita.fr>
9573 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
9574 willing to edit the output files.
9576 2003-09-10 Akim Demaille <akim@epita.fr>
9578 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
9580 * tests/mktests.sh: Skip AC_FC_SRCEXT.
9581 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
9583 2003-09-09 Akim Demaille <akim@epita.fr>
9585 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
9586 Reported by Gary Vaughan.
9587 * bin/autom4te.in (handle_m4): Likewise.
9589 2003-09-09 Akim Demaille <akim@epita.fr>

9601 2003-09-05 Paul Eggert <eggert@twinsun.com>
9603 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
9604 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
9606 2003-09-04 Akim Demaille <akim@epita.fr>
9608 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
9611 2003-09-04 Akim Demaille <akim@epita.fr>
9613 * bin/autom4te.in: Use &fatal where more appropriate than &error.
9614 (freeze): When exiting, use $exit_code.
9615 * lib/autoconf/fortran.m4: Comment changes.
9617 2003-09-04 Akim Demaille <akim@epita.fr>
9619 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
9621 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
9623 Add support for newer Fortran dialects. The F77 interface is
9624 unchanged, and continues to support Fortran 77. New FC macros
9625 correspond to all the old F77 macros, with output variables FC,
9626 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
9627 available dialect, but older dialects can be specified. There are
9628 new macros AC_FC_SRCEXT to set the source extension, and
9629 AC_FC_FREEFORM to accept free-form source files.
9631 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
9633 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

9662 2003-08-27 Akim Demaille <akim@epita.fr>
9664 * tests/m4sugar.at (cross_warning): Make sure to enable the
9665 output, so that we can track spurious m4sugar output.
9666 * tests/local.at: Require 2.57.
9667 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
9668 are defaulted by AT_CHECK anyway.
9669 Use AT_CHECK_AUTOM4TE.
9670 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a

9729 * bin/autom4te.in: Adjust to output the call stack.

9732 2003-08-22 Akim Demaille <akim@epita.fr>
9734 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.

9745 Use &verb, not &verbose.
9747 2003-08-21 Akim Demaille <akim@epita.fr>
9749 * bin/autoheader.in (&parse_args): Use &parse_warnings and
9751 ($help): Use Autom4te::ChannelDefs::usage.
9752 * bin/autoscan.in: Use Autom4te::ChannelDefs.
9753 * lib/Autom4te/General.pm: Don't export error: you don't own it.
9755 2003-08-21 Akim Demaille <akim@epita.fr>
9757 First stab at preserving warnings between calls to autom4te,
9758 including when the cache is used.
9760 There are still several issues: (i) there are too many runs of m4
9761 (one for include, one for warnings, and some more), (ii) warnings
9762 spreading on several lines are not handled gracefully, (iii) the
9763 code meant to have the call stack display for errors does not work
9764 (its handling should move from m4 to autom4te).
9766 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
9768 (@preselect): Add m4_warn.
9769 ($exit_status): Remove, use $exit_code.
9770 ($help): Use Autom4te::ChannelDefs::usage.
9771 (&handle_m4): No longer define the m4_warnings.
9772 At each run, extract and report the warnings.
9773 Always cache the result, including if the exit status is on
9774 failure, since if nothing changes, we should result in the same
9775 failure, hence we can use the cache.
9776 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
9777 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
9779 (m4_warn): Redefine as a do-nothing: it is its invocation that
9780 matters, as warnings are now reported via traces.
9781 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
9782 the contents of m4_warn: make it _call_ m4_warn, so that tracing
9783 the latter reveals calls to the former.
9787 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
9789 2003-08-21 Akim Demaille <akim@epita.fr>
9791 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
9794 2003-08-21 Akim Demaille <akim@epita.fr>
9796 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
9798 * lib/Autom4te/ChannelDefs.pm: Doc typos.
9799 (&parse_warnings): Accept a list of warning requests.
9800 (&usage): Return a string, not a side effect.
9801 (cross): New warning category.

9806 (&require_configure_ac): Accept an optional directory argument.

9810 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
9811 * bin/autoscan.in: Adjust.
9813 2003-08-20 Akim Demaille <akim@epita.fr>
9815 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
9816 Reported by Alexandre Duret-Lutz.
9818 2003-08-20 Akim Demaille <akim@epita.fr>
9820 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
9821 * bin/autom4te: Adjust.
9822 In particular, be Autoconf tools are really silent when properly
9823 working, bind the verbosity of the 'note' channel to $verbose.
9824 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
9825 (&xsystem, &contents): Remove, since they are exported by...
9826 * lib/Autom4te/FileUtils.pm: this.
9828 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
9829 * lib/Autom4te/FileUtils.pm: here.

9887 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
9888 shorter column three. Add DESCRIPTION to log file content.
9890 2003-08-13 Derek Price <derek@ximbiot.com>
9892 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

9948 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
9949 not all of them. This fixes 1. the fact that when testing
9950 Autoconf there are many many config.log, 2. the incorrect use of
9951 top_srcdir to find config.log.
9952 Don't mix the detailed output of failed test with the summary of
9953 failures. Rather, append detailed log afterwards.

10015 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
10016 (AT_INIT): Support for expected failures.
10018 2003-06-02 Akim Demaille <akim@epita.fr>

10027 2003-05-28 Paul Eggert <eggert@twinsun.com>
10029 * NEWS, doc/autoconf.texi (Particular Functions),
10030 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
10031 is the inverse of localtime.
10033 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
10035 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10036 (handle_exec_errors): New function. Work around $! being
10037 altered by WEXITSTATUS.
10038 (xqx, xsystem): Use handle_exec_errors.
10040 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10042 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10043 Do not call `_exit()', simply modify `$?'.
10044 (xsystem): Reset $! before running system, and check it afterward.
10045 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10046 63 for version mismatches.
10048 2003-05-23 Akim Demaille <akim@epita.fr>
10050 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10051 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10052 the middle of a line).
10053 * lib/m4sugar/m4sugar.m4: Likewise.
10054 Remove useless spaces in comments.
10056 2003-05-23 Akim Demaille <akim@epita.fr>
10058 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10059 exit 63, so that we (or Automake's "missing") can tell the
10060 difference with a plain failure.
10061 * doc/autoconf.texi (Notices): Adjust.

10070 Paul Eggert <eggert@twinsun.com>
10072 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10073 Remove `#include <stdlib.h>' from the list; we should never
10074 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10075 resulting namespace pollution would cause other tests to fail.
10076 Configure scripts run with some older versions of g++ and HP's
10077 aCC would fail due to such an #include. Problems reported by
10078 Matthew Mueller in <http://bugs.debian.org/120704> and by
10080 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10081 In the test, use the test declaration before including <stdlib.h>,
10082 as that's closer to how it'll be used.
10084 2003-05-23 Akim Demaille <akim@epita.fr>
10086 * doc/autoconf.texi (Header Portability): ucred.h.
10089 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10091 Overhaul Autotest's logging: generate separate log files
10092 in testsuite.dir/NNN/testsuite.log, and append them to
10093 testsuite.log instead of re-running the test verbosely.
10095 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10096 file descriptor, write 0 to at_status_file instead of setting
10097 at_status=0, initialize some new variables (at_status_file,
10098 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10099 to rerun the tests, instead append the at_group_log to the
10100 at_suite_log when a test fails.
10101 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10102 with the AS_MESSAGE_LOG_FD redirected to stdout.
10103 (AT_CLEANUP): save the output status in $at_status_file
10104 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10105 its original place.
10106 (AT_CHECK): since tests are run with a redirected stdout,
10107 and used to be re-run in verbose mode, turn some $at_verbose
10108 into echo, and don't redirect the output of testing stdout
10111 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10112 the name of the debugging directory and information about
10115 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

10232 2003-05-06 Akim Demaille <akim@epita.fr>
10234 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10235 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10236 by aclocal.m4 is changed it might require the importing of another
10237 m4 extension file, i.e., aclocal must be run.
10239 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10240 (&parse_args): Use --force with aclocal if required and supported.

10254 2003-04-29 Derek Price <derek@ximbiot.com>
10256 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10257 seperator with m4_append_uniq(). It doesn't work.
10258 (AT_CLEANUP): Add `;' to end of at_help_all.
10259 (AT_INIT): Allow --keywords to be specified more than once. When
10260 grepping $at_help_all for keywords, use the field and keyword
10261 seperators to ensure a complete keyword match. Alter at_prev handling
10262 to support the new --keywords behavior.
10264 2003-04-27 Karl Berry <karl@freefriends.org>
10266 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10267 align better with others. I also made some of the individual
10268 entries on one line, for brevity and to make it easier for me to
10269 sort my dir-example file in the Texinfo distribution :).

10340 * tests/torture.at (Configuring subdirectories): Require aclocal

10484 $ac_prefix_program.
10487 2002-12-23 Paul Eggert <eggert@twinsun.com>
10489 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10490 innocuous variant befor including <limits.h> or <assert.h>. This
10491 works around a bug reported by Albert Chin: HP-UX 11i
10492 (and earlier versions) have a <limits.h> that declares
10493 gettimeofday and many other functions.
10495 2002-12-03 Paul Eggert <eggert@twinsun.com>
10499 * NEWS, configure.ac: Update version.
10501 * doc/fdl.texi: Upgrade to FDL version 1.2.
10503 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
10504 nontrivially in main's body, so that f's external declaration is
10505 not optimized away in AIX. This should fix the bug reported by
10507 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
10509 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10510 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10511 defined, to support freestanding compilers. This should fix the
10512 bug reported by Momchil Velkov in
10513 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10515 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10516 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

10547 Update from masters.
10549 2002-11-14 Akim Demaille <akim@epita.fr>
10551 * Makefile.maint: Sync with Bison, i.e.:
10552 (po-check): Scan .l and .y files instead of the
10553 .c and the .h files that they generate. This fixes the bug
10554 reported by Tim Van Holder in:
10555 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
10556 Look for N_ as well as for _. Try to avoid matching #define for

10572 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
10573 than assigning in main, to avoid HP cc +O3 optimizing it away.

10577 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
10578 option. Process --recheck after parsing all options. Pass -q
10579 option to configure on --recheck.
10580 (AC_OUTPUT): Pass -q from configure to config.status.
10581 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
10582 arguments to record.
10583 * doc/autoconf.texi (config.status Invocation): Document
10584 config.status -q option.
10586 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
10588 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
10589 Makefile.in if Makefile.am exists.

10611 Reported by Ezra Peisach.
10613 2002-11-05 Akim Demaille <akim@epita.fr>
10615 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
10617 We _have_ to stop using the old compatibility scheme that tried to
10618 avoid useless backslashes because Libtool 1.4.3 contains a
10619 AC_DEFINE([error_t], [int],
10620 [Define to a type to use for \`error_t' if it is not
10621 otherwise available.])
10622 We _have_ to quote the single quote and backslashes with \. The
10623 old compatibility scheme saw that ` was backslashed, and therefore
10624 did not quote the single quote. Hence before this patch, Autoconf
10625 was not compatible with Libtool.
10627 2002-11-04 Paul Eggert <eggert@twinsun.com>
10629 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

10670 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
10671 Make variable, not a shell variable.
10672 Suggested by Bruno Haible.
10674 2002-10-31 Akim Demaille <akim@epita.fr>
10676 * bin/autom4te.in (load_configuration): Reject #args out of any

10699 Problem reported by Bruno Haible.

10987 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
10989 * tests/tools.at (autom4te): Now it does exit 1.
10991 2002-10-17 Akim Demaille <akim@epita.fr>
10993 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
10994 Fixes the `AC_ARG_VAR' test failures.
10995 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
10996 * lib/freeze.mk (check-forbidden-patterns): New.
10997 * lib/autoconf/Makefile.am, lib/autotest/Makefile.am
10998 * lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
10999 * doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
11001 Reported months ago by H. Merijn Brand.
11003 2002-10-17 Akim Demaille <akim@epita.fr>
11005 * tests/tools.at (autoheader): Put randoms `@' to stress Perl.
11007 2002-10-16 Paul Eggert <eggert@twinsun.com>
11009 * Makefile.maint (wget_files): Remove ansi2knr.c.
11010 (ansi2knr.c-url_prefix): Remove.
11012 2002-10-16 Akim Demaille <akim@epita.fr>
11014 Because of caching, some files that no longer exist and are no
11015 longer required can still cause errors.
11016 Reported by Alexandre Duret-Lutz.
11018 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
11019 to frozen files in @ARGV, as @ARGV must remain being a list of
11020 files. Rather, at M4 call sites, use this...
11021 (&files_to_options): New function.
11022 (&freeze): Use &error.
11023 (&up_to_date): If a file that was included according to the cache
11024 is no longer there, then the output is out dated.
11025 (&main): Don't even check whether a file is up to date is anyway
11027 * tests/tools.at (autom4te cache): New.
11029 2002-10-16 Akim Demaille <akim@epita.fr>
11031 * bin/autoconf.as: Kill dead options.
11032 * bin/autoupdate.in (&parse_args): Kill old options.
11033 * bin/autoreconf.in (&parse_args): Remove dead options.
11035 (&autoreconf): Report the directories we enter *and leave*, so
11036 that error messages can be easily located, and use GNU Make
11037 format, so that Emacs' compile mode understands us.
11038 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11039 if some file was changed instead of `print'.
11040 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
11041 (&parse_args): Remove the dead options.
11042 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
11043 autoheader's quiet mode.
11044 (AT_CHECK_AUTOUPDATE): Likewise.
11045 * tests/tools.at (autoupdate): Adjust.
11046 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
11048 2002-10-11 Akim Demaille <akim@epita.fr>
11050 No longer use CPP to check for the existing of headers: use CC to
11051 check for compilability.
11053 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
11054 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
11055 (_AC_CHECK_HEADER_NEW): Rename as...
11056 (AC_CHECK_HEADER): this.
11058 * lib/autotest/general.m4 (AT_INIT): Include the failed test
11059 numbers in the Subject suggestion.
11061 2002-10-11 Akim Demaille <akim@epita.fr>
11063 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
11064 Suggest using AC_CHECK_DECLS instead.
11066 2002-10-11 Akim Demaille <akim@epita.fr>
11068 * tests/torture.at (AC_ARG_VAR): Have configure report the value
11071 2002-10-11 Akim Demaille <akim@epita.fr>
11073 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
11074 file name to enable parallel executions.
11075 From Sam Varshavchik.
11077 2002-10-08 Akim Demaille <akim@epita.fr>
11079 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11080 aclocal invocation, as Gettext macros might not be visible to
11082 Instead of blindly running autopoint, scan configure.ac (not the
11083 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11084 Reported by Paul D. Smith.
11086 2002-10-08 Paul Eggert <eggert@twinsun.com>
11088 Work around problems found when POSIXLY_CORRECT=1 is set.
11089 None of this seems to have anything to do with POSIX, really,
11090 but it's how Perl getopt works.
11091 * bin/autom4te.in (parse_args): Configure GetOpt with
11093 * doc/autoconf.texi (Invoking autom4te):
11094 --warning -> --warnings.
11095 * lib/autom4te.in: --warning -> --warnings.
11097 2002-09-28 Akim Demaille <akim@epita.fr>
11099 * doc/autoconf.texi (autom4te.cache): New section.
11101 2002-09-28 Akim Demaille <akim@epita.fr>
11103 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
11104 (Automake-preselections): Update.
11105 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
11107 2002-09-28 Akim Demaille <akim@epita.fr>
11109 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
11110 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
11111 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11112 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
11114 2002-09-28 Akim Demaille <akim@epita.fr>
11116 * tests/torture.at (Configuring subdirectories): Be robust to
11117 users who use config.site to require for a cache: in this case,
11118 the two last configure runs, using two different sets of
11119 arguments, trigger a legitimate error.
11121 2002-09-28 Akim Demaille <akim@epita.fr>
11123 * tests/m4sh.at (Functions Support, Functions and return Support):
11126 2002-09-28 Akim Demaille <akim@epita.fr>
11128 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
11129 autoheader are Perl programs.
11130 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
11131 (autom4te): Specify that the sources are in the $srcdir.
11132 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11134 2002-09-28 Akim Demaille <akim@epita.fr>
11136 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
11137 (tm_zone): Move their rules to...
11138 * lib/autoconf/types.m4: here, using AN_ macros.
11139 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11140 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11141 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
11142 * lib/autoconf/programs.m4: here.
11143 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
11144 (ETAGS_FOR_AUTOCONF): New.
11147 2002-09-28 Akim Demaille <akim@epita.fr>

11151 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
11152 that were listed in the original autoscan.list.
11153 * lib/autoconf/headers.m4: Similarly with headers.
11154 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11155 (.m4.m4f): Don't pass --prepend-include, since that's done by
11156 tests/autom4te itself.
11157 * lib/autoscan/Makefile.am: Include freeze.mk.
11158 (autoscan.list): New target --this file is no longer a source.
11159 (autoscan.pre): New file.
11161 2002-09-28 Akim Demaille <akim@epita.fr>
11163 * bin/autoscan.in (@kinds): Make them singular.
11165 (&init_tables): When --debug, report the list of rules to ease
11166 tracking changes in autoscan.list.
11167 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11169 2002-09-28 Akim Demaille <akim@epita.fr>
11171 * lib/autoscan/functions, lib/autoscan/headers,
11172 * lib/autoscan/identifiers, lib/autoscan/makevars,
11173 * lib/autoscan/programs: Merge into...
11174 * lib/autoscan/autoscan.list: this.
11175 * bin/autoscan.in (&init_tables): Adjust.
11177 2002-09-28 Akim Demaille <akim@epita.fr>
11179 * lib/autoscan/functions, lib/autoscan/headers,
11180 * lib/autoscan/identifiers, lib/autoscan/makevars,
11181 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11182 `functions' line is now prefixed with `function:'.
11183 * bin/autoscan.in (&init_tables): Adjust.
11185 2002-09-28 Akim Demaille <akim@epita.fr>
11187 From now on, autoscan files must always map a macro name to a
11188 word: there is no `default' macro for autoscan.
11190 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11192 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11195 2002-09-28 Akim Demaille <akim@epita.fr>
11197 * bin/autoscan.in (%c_keywords): Remove.
11198 (&used): Keep only track of the words we might be interested in.
11199 (&output_kind): It is no longer needed to look for non active
11202 2002-09-27 Akim Demaille <akim@epita.fr>
11204 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
11205 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
11206 * lib/autoscan/functions: Adjust.
11207 * doc/autoconf.texi (Particular Functions): Adjust.
11209 2002-09-27 Akim Demaille <akim@epita.fr>
11211 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
11213 Thanks to Bill Moseley and Paul Eggert.
11214 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
11215 the tmpdir must be created.
11216 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
11217 dir be in the build tree, instead of $TMPDIR.
11219 2002-09-27 Akim Demaille <akim@epita.fr>
11221 * bin/autoscan.in: Improve the comments.
11222 (&parse_args): Drop obsolete undocumented options.
11223 (&output_kind): Output warnings.
11224 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
11225 (getwd): Trigger a warning.
11227 2002-09-26 Akim Demaille <akim@epita.fr>
11229 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
11230 Reported by Ralf Corsepius.
11231 * doc/autoconf.texi (autoreconf Invocation): Likewise.
11233 2002-09-26 Akim Demaille <akim@epita.fr>
11235 Single suffix rules and seperated dependencies are not portable.
11237 * doc/autoconf.texi (Installation Directory Variables): Update.
11238 (Limitations of Make): Some about `Single Suffix Rules and
11239 Separated Dependencies'.
11240 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11241 (ifnames, autoscan, autom4te): Un-factor into several rules.
11243 2002-09-25 Paul Eggert <eggert@twinsun.com>
11245 * BUGS (Interoperability bugs): New section. Mention libtool
11246 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
11248 2002-09-24 Paul Eggert <eggert@twinsun.com>
11250 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
11251 make handles suffix-rules differently from GNU make.
11253 * bin/Makefile.am (SUFFIXES, .in): Remove.
11254 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
11255 Move the body of the old .in rule here.
11257 2002-09-16 Akim Demaille <akim@epita.fr>
11259 i960 compilers create `b.out' files by default.
11260 Reported by Ralf Corsepius.
11262 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
11263 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
11265 2002-09-13 Paul Eggert <eggert@twinsun.com>
11267 * doc/autoconf.texi (Particular Headers): Remove obsolete
11268 reference to `struct timezone' in the description of
11271 2002-09-13 Akim Demaille <akim@epita.fr>
11275 * config/config.sub, config/config.guess: Update.
11276 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
11277 * Makefile.am: Adjust.
11279 2002-09-13 Akim Demaille <akim@epita.fr>
11281 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
11282 reading config.log when the compiler is rejected.
11283 Suggested by Guido Draheim.
11285 2002-09-13 Akim Demaille <akim@epita.fr>
11287 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11288 (chdir_init) might hang when stat'ing mounted directories.
11289 Reported by Vance Shipley.
11291 2002-09-12 Akim Demaille <akim@epita.fr>
11293 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
11296 2002-09-12 Akim Demaille <akim@epita.fr>
11298 * doc/autoconf.texi (Defining Symbols): Present two different
11299 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
11300 difference between 1 argument calls, and 2-3 argument calls.
11302 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
11304 * doc/autoconf.texi: Review grammar and punctuation.
11306 2002-09-11 Paul Eggert <eggert@twinsun.com>
11308 * doc/autoconf.texi: Fix minor formatting, spelling, and
11310 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
11311 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
11314 2002-09-11 Akim Demaille <akim@epita.fr>
11316 * doc/autoconf.texi (Questions): Rename as...
11318 (Defining Directories): New.
11320 2002-09-09 Akim Demaille <akim@epita.fr>
11322 * doc/autoconf.texi (Making testsuite Scripts): Update.
11323 Suggested by Nishio Futoshi.
11325 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
11327 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
11328 plain `@' is wanted.
11330 2002-09-09 Akim Demaille <akim@epita.fr>
11332 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11333 `duplicates', since the algorithm was too naive and could keep
11334 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11335 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11336 Reported by Ralf Corsepius.
11337 * tests/torture.at (Configuring subdirectories): Exercise these
11340 2002-09-09 Akim Demaille <akim@epita.fr>
11342 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
11343 looking for a replacement file.
11344 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11345 directory is relative.
11346 * doc/autoconf.texi (Generic Functions): Clarify the replacement
11347 directory definition.
11348 Reported by Andreas Schwab and Jim Meyering.
11350 2002-09-06 Akim Demaille <akim@epita.fr>
11352 * doc/autoconf.texi (Setting Output Variables): Clarify what
11353 precious variables are.
11354 Suggested by Pontus Skoeld.
11356 2002-09-05 Akim Demaille <akim@epita.fr>
11358 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11359 (ifnames, autoscan, autom4te): Since we don't only depend on
11360 configure.ac variables (such as VERSION etc.), but also on prefix
11361 and so forth, depend on Makefile, not configure.ac.
11362 Reported by Alexandre Duret-Lutz.
11363 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11365 2002-09-05 Kevin Ryde <user42@zip.com.au>
11367 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11368 doesn't seem to be confined to ia64, just say "some versions".
11370 2002-09-04 Akim Demaille <akim@epita.fr>
11372 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11374 * Makefile.am (maintainer-clean-local): Remove.
11375 (MAINTAINERCLEANFILES): Remove COPYING.
11377 2002-09-03 Paul Eggert <eggert@twinsun.com>
11379 * doc/autoconf.texi (Configuration Commands): Remove obsolete
11380 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
11383 2002-09-03 Akim Demaille <akim@epita.fr>
11385 * configure.ac: Bump to 2.53d.
11386 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11387 as of today, on Automake's team suggestion.
11389 2002-09-03 Akim Demaille <akim@epita.fr>
11393 2002-09-02 Akim Demaille <akim@epita.fr>
11395 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
11397 * configure.ac: Disable SITE_MACRO_DIR.
11399 2002-09-02 Jim Meyering <meyering@lucent.com>
11401 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11402 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11403 Also, tweak grammar: s/make sure to/be sure to/.
11405 2002-09-02 Paul Eggert <eggert@twinsun.com>
11407 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11408 directory names are generally preferable to physical names.
11410 2002-09-02 Akim Demaille <akim@epita.fr>
11412 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11413 Reported by Raja R. Harinath.
11414 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11415 * bin/autoupdate.in: Use error instead of die.
11417 2002-09-01 Paul Eggert <eggert@twinsun.com>
11419 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11420 ordinary shell concatenation rather than echo+tr+sed command that
11421 runs afoul of a long-line-related sed bug in Solaris 8.
11423 * bin/autoheader.in (parse_args): --warning -> --warnings.
11425 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11426 stdout, as traditional "ls" does.
11427 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11428 _AC_COMPILER_EXEEXT_O): Likewise.
11429 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11431 * bin/autoconf.as: Add --prepend-include option. This patch was
11432 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11433 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11435 * bin/autoconf.in, configure: Regenerate.
11437 * doc/autoconf.texi (Special Shell Variables): Mention
11438 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11440 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11441 MAILPATH and set PS1, PS2, PS4 to default values, to work
11442 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11443 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11444 the Autoconf documentation specifies; fall back to "unset" only if
11445 this fails. Use a shell for-loop for this rather than an m4 loop,
11446 to shorten the output script.
11448 2002-08-30 Paul Eggert <eggert@twinsun.com>
11450 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11451 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11452 for the CDPATH problem. Document PWD.
11453 (Limitations of Builtins): Document the problem that "cd $foo" and
11454 "ls $foo" may refer to different directories in shells conforming
11455 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11456 example, since the old example is now out of date.
11458 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11459 FOO" and "ls FOO" talk about different directories; this catches
11460 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11463 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11464 of rolling our own unset.
11465 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
11466 in practice we needn't worry about CDPATH if unset doesn't work.
11468 * Makefile.in, aclocal.m4, bin/Makefile.in,

11492 * lib/Autom4te/General.pm (&xqx): New.
11493 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11494 hand, which is not portable.
11496 * bin/autom4te.in: Use them.
11497 Use &error instead of die.

11503 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the

11509 * doc/autoconf.texi (Invoking autom4te): End the option table,

11531 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
11532 * Makefile.am (INSTALL): Use the new macros.

11677 2002-06-27 Paul Eggert <eggert@twinsun.com>

11821 This improves on an earlier suggestion by H. Peter Anvin.
11823 2002-05-16 Paul Eggert <eggert@twinsun.com>
11825 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
11826 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
11827 Both macros now accept an optional source-dir arg.
11828 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
11830 * NEWS: Document this.
11831 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
11833 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
11834 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
11835 not for GNU extensions; this undoes part of the 2000-11-03 change,
11836 reverting to 2.13-compatible behavior.
11837 Add new optional argument DIR.
11838 (AC_FUNC_FNMATCH_GNU): New macro.
11840 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.

11844 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
11845 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
11846 and it causes a 'test' syntax error if it fails.
11847 Bug reported by Stephen Gildea.
11849 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
11850 If prototypes are supported, use them to check this at compile-time,
11851 instead of trying to check it at run-time. If we must do a run-time
11852 check, assume that setvbuf is standard when cross-compiling, as
11853 nonstandard setvbuf occurs only on ancient and unlikely hosts.
11854 Bug reported by Paul D. Smith.
11856 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
11857 argument specifying location of getloadavg.c. This removes a
11858 FIXME. This idea was taken from Jim Meyering's implementation in
11860 * doc/autoconf.texi (Particular Functions): Document this.
11861 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
11862 that's what the code does; this fixes a bug reported by
11865 2002-05-03 Akim Demaille <akim@epita.fr>
11867 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
11868 autopoint instead of gettextize.
11869 ($uses_alocal): Rename as...
11870 ($uses_aclocal): this.
11871 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11872 Suggested by Bruno Haible.
11874 2002-05-03 Akim Demaille <akim@epita.fr>
11876 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
11878 2002-04-29 Paul Eggert <eggert@twinsun.com>
11880 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
11881 files to be 1 second older; just set them to be the same time.
11882 Also, sleep 1 second after the first aclocal, to work around
11883 problems with sub-second time stamps on the input files.
11885 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
11887 * doc/autoconf.texi: Mention "set -e -x" lossage
11888 under node "Limitations of Builtins".
11890 2002-04-29 Akim Demaille <akim@epita.fr>
11892 * doc/install.texi: Better wording for setting variables when
11894 From Christian Cornelssen.
11896 2002-04-29 Akim Demaille <akim@epita.fr>
11898 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
11899 of lack of $LINENO support, then the test will compare the $LINENO
11900 in testsuite vs. the lineno in the test file. This is wrong, of
11902 Be sure to protect it.
11903 Reported by Patrick Welche.
11905 2002-04-25 Akim Demaille <akim@epita.fr>
11907 * doc/autoconf.texi (Obsolete Macros): Typo.
11908 Reported by Vladimir Volovich.
11910 2002-04-25 Akim Demaille <akim@epita.fr>
11912 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
11913 than some of the input files, hence, on the second run of aclocal,
11914 if some of its input are younger, make them older.
11915 Suggested by Paul Eggert.
11917 2002-04-25 Akim Demaille <akim@epita.fr>
11919 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

11925 and ac_subst_vars be sh variables containing the list of
11926 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
11928 (_AC_INIT_PREPARE): Use them to log them.
11929 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
11930 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
11931 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
11932 _AC_SUBST_FILES and _AC_SUBST_VARS.
11933 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
11935 2002-04-24 Akim Demaille <akim@epita.fr>
11937 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
11938 autoheader, so that automake does not complain about a missing
11939 config.h.in that was to be created.
11941 2002-04-23 Akim Demaille <akim@epita.fr>
11943 * bin/autoheader.in (parse_args): --warning takes an argument.
11946 2002-04-22 Peter Eisentraut <peter_e@gmx.net>

11993 Minor spelling and grammar fixes.
11995 * doc/autoconf.texi: Follow the outline suggested in the GNU
11996 Sample Texts sections of the Texinfo 4.2 manual. Most
11997 importantly, this makes sure that the copyright notices appear in
11998 all output formats. You probably need Texinfo 4.2 to generate

12038 * doc/autoconf.texi (Shell Substitutions): Explain it.
12039 From Oliver Kiddle and Peter Stephenson.
12041 Have M4sh perform minimal shell sanitizing.
12043 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12045 (_AS_PREPARE): this new macro.
12047 (AS_INIT): Invoke AS_SHELL_SANITIZE.

12050 Adjust Autoconf and Autotest.
12052 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12053 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.

12061 * tests/wrapsh.as: New, precursor of wrapsh.in.
12062 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12063 on Autotest and M4sh.
12064 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12065 (wrapsh.in): New target.

12099 Use dnl, not the KILL diversion.
12101 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12102 (AC_CONFIG_LINKS): here.
12104 Don't use the KILL diversion, as it kills spurious output, which
12105 results in failures being hidden.
12106 Use m4_defn where appropriate.
12107 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12108 after the second argument.
12110 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12111 syntax, as it is provided by M4sugar.

12154 to avoid versions of HP C which don't allow that.
12156 2002-03-27 Paul Eggert <eggert@twinsun.com>
12158 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

12172 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12173 as POSIX requires, as it doesn't work with Zsh.
12174 * doc/autoconf.texi (Assignments): Document the problem.
12176 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

12184 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12185 problem with here-document buffer boundaries.
12187 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12188 when reinvoking the shell, to work around problems with installers
12189 who put strange things like "cd" commands in their environments.

12214 (Limitations of Usual Tools): Add mkdir section.
12216 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12217 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12218 back on AS_DIRNAME to compute prefixes otherwise; this is
12219 roughly what mkinstalldirs does. That way, we need not have
12220 our own filename disassembler. The old disassembler did not
12221 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12223 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12224 Create at_test_all by a series of assignments,
12225 not by a single assignment of a long string. The latter causes ksh
12226 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12227 presumably because of a buffer overrun.
12229 2002-03-14 Paul Eggert <eggert@twinsun.com>
12231 * lib/autotest/general.m4 (at_times_skip):
12232 Renamed from at_times. Now a boolean.
12233 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12234 says 'times: not found'.

12277 2002-03-08 Akim Demaille <akim@epita.fr>
12279 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12281 2002-03-08 Akim Demaille <akim@epita.fr>
12283 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12284 aliases the actual variables, and modifications of the former
12287 2002-03-08 Akim Demaille <akim@epita.fr>
12289 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12290 because of C-c: have m4 output in tmp files, then mv them.

12324 * doc/autoconf.texi (Transforming Names): Equality between target
12325 and host is irrelevant.
12326 (Specifying Names, Canonicalizing): Remove all references to the
12327 backward compatibility hooks. Rather, collect them all into...
12328 (Hosts and Cross-Compilation): this new section.
12329 * doc/install.texi (System Type): Ditto.
12330 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12331 that `--host' implies cross-compilation.

12335 * doc/autoconf.texi (Evaluation Macros): New.
12336 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12338 (_m4_foreach): Define the variant with immediate evaluation so
12339 that it contains exactly the items, not an expression which
12340 evaluation is the current item.
12341 (m4_re_string, m4_re_word): Don't over quote them.
12343 2002-03-04 Akim Demaille <akim@epita.fr>
12345 Instead of having stacking `shift's evaluated at the end, let
12346 `foreach' loops immediately evaluate them.
12348 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12349 $*. This is the n-th time I change my mind, but hopefully this is
12352 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12354 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12355 it was only a hack for m4_text_wrap.
12356 (m4_car2): Remove, replaced by...
12358 (_m4_foreach): Adjust.
12359 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12360 m4_bpatsubst for clarification.

12467 Implement `autom4te --freeze'.
12469 * bin/autom4te.in (&freeze): New.
12470 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
12471 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
12473 2002-02-05 Akim Demaille <akim@epita.fr>
12475 * bin/autom4te.in (&parse_args): Implement `frozen files are
12476 optional are the sum of the previous files on the command line'.
12477 Also, pass `--reload-state=' on them, so...
12478 (handle_m4): don't.
12479 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
12480 (M4sh): Rely on M4sugar.
12481 (Autotest, M4sh, M4sugar): Use frozen files.
12483 2002-01-31 Akim Demaille <akim@epita.fr>
12485 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
12486 * doc/autoconf.texi (Initializing configure): Adjust.
12488 2002-01-30 Akim Demaille <akim@epita.fr>
12490 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
12491 alphanumeric to `-' instead of `_'.
12493 2002-01-30 Akim Demaille <akim@epita.fr>
12495 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
12496 for plain code, the other for cross-compilation code. The latter
12497 is now run with GCC only.
12498 * doc/autoconf.texi (Compilers and Preprocessors): New.
12500 2002-01-30 Akim Demaille <akim@epita.fr>
12502 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined

12505 change AC_INIT default values.
12507 2002-01-29 Akim Demaille <akim@epita.fr>
12509 * tests/torture.at (Configuring subdirectories): Use configure.in,
12510 so that aclocal 1.4 works.
12511 Reported by Alexandre Duret-Lutz and Larry Schmitt.
12513 2002-01-28 Akim Demaille <akim@epita.fr>
12515 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
12518 2002-01-28 Akim Demaille <akim@epita.fr>
12520 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12521 AUTOTEST_PATH *after* it was set.
12522 Don't put `.' in the PATH: the user should be precise and `./' if
12523 needed. In addition, given that the test suite does some `cd', if
12524 `.' is in the path, the `tested programs' sections will report
12525 programs found in the test suite's directory, while during the
12526 tests (performed in their own directory), these programs are no
12527 longer visible. In other words, the results is confusing and
12529 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
12531 2002-01-24 Akim Demaille <akim@epita.fr>
12535 2002-01-24 Akim Demaille <akim@epita.fr>

12538 * doc/autoconf.texi: Finally add Akim as an author.
12540 2002-01-24 Akim Demaille <akim@epita.fr>
12542 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
12543 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
12544 Bourne. Use /bin/sh.
12545 From Andreas Buening.
12547 2002-01-24 Akim Demaille <akim@epita.fr>
12549 * config/config.guess, config/config.sub, config/texinfo.tex:
12550 Update from masters.
12552 2002-01-24 Akim Demaille <akim@epita.fr>

12571 2002-01-21 Akim Demaille <akim@epita.fr>
12573 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
12574 message on invalid options.
12575 * bin/autom4te.in (parse_args): Don't use
12576 Autoconf::General::getopt with non valid options.
12578 2002-01-17 Jim Meyering <meyering@lucent.com>
12580 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
12581 $ac_cv_exeext so we don't use an old, invalid, cached value.
12583 2002-01-11 Akim Demaille <akim@epita.fr>

12594 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
12595 package.m4, since is really depends upon configure.ac, not
12597 * doc/autoconf.texi (testsuite Scripts): Adjust.
12598 * tests/Makefile.am (package.m4): New.
12599 EXTRA_DIST it since its a source.
12601 2002-01-06 Akim Demaille <akim@epita.fr>
12603 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
12604 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
12605 and PACKAGE_BUGREPORT from here...
12606 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
12608 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
12609 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
12610 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
12611 * tests/tools.at (autoheader): Adjust.
12612 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
12614 2002-01-06 Akim Demaille <akim@epita.fr>

12629 2001-12-17 Jim Meyering <meyering@lucent.com>
12631 * doc/autoconf.texi (New Macros): Tweak wording.
12633 2001-12-14 Akim Demaille <akim@epita.fr>
12635 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
12636 trailing files, don't apply `-rf' to files which might not be
12637 created by configure (core, core.*, and *.core), but just `rm -f'.
12638 Suggested by Jonathan Kamens.
12640 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
12642 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
12644 2001-12-14 Akim Demaille <akim@epita.fr>
12646 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
12648 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
12650 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
12651 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
12652 abs_srcdir, top_srcpath to abs_top_srcdir.
12653 (_AC_OUTPUT_FILES): Adjust.
12654 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
12655 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
12656 * tests/wrappl.in, tests/wrapsh.in: Adjust.
12658 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>

12664 2001-12-12 Kevin Ryde <user42@zip.com.au>
12666 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
12667 forbidden file descriptors table.
12669 2001-11-26 Akim Demaille <akim@epita.fr>
12671 * bin/autoscan.in (%c_keywords): Build it at top level.
12672 Map to 1 in order to simplify its uses.
12674 2001-11-26 Akim Demaille <akim@epita.fr>
12676 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
12677 Remove $filepath, useless.
12678 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
12679 variables, they are really part of the tokens.
12680 Split the input line on spaces and then look for tokens.
12681 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
12682 because of `lex$U.$(OBJEXT)'.
12683 (&scan_files): Use "@list" instead of join.
12684 * doc/Makefile.am (CLEANFILES): Add *.fns.
12686 2001-11-26 Akim Demaille <akim@epita.fr>

12689 Remove, replaced by...
12690 * tests/wrappl.in: Be common for all the Perl executables.
12691 In particular autoscan and autoheader want -I.
12692 * configure.ac: Adjust.
12693 * lib/autoscan/headers: errno.h is portable.
12695 2001-11-26 Akim Demaille <akim@epita.fr>
12697 * bin/autoscan.in (used): New.
12700 2001-11-26 Akim Demaille <akim@epita.fr>
12702 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
12704 (&scan_sh_file): Remove a duplicate pattern.
12705 (&check_configure_ac): Use long options.
12706 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.

12711 Before, having a line containing the opening of a multi line
12712 comment made the whole line be ignored.
12714 2001-11-26 Akim Demaille <akim@epita.fr>
12716 * doc/autoconf.texi (Using an Autotest Test Suite): New.

12722 Test groups are now run two directories deeper.
12724 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
12725 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
12727 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
12728 top_srcdir, builddir and top_builddir.
12729 Use `at_*dir' relatively to the directory containing the
12730 suite, use `*dir' when relatively to the current group dir.
12732 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
12734 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
12735 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
12736 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
12739 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12741 * doc/autoconf.texi (Using System Type): Add an example of `case
12742 $host' usage so people quit using `case $target' everywhere.
12744 2001-11-22 Akim Demaille <akim@epita.fr>
12746 * doc/autoconf.texi (Installation Directory Variables): Englishoes
12747 spotted by Jim Meyering.
12749 2001-11-16 Paul Eggert <eggert@twinsun.com>
12751 This patch implements a `long double' suggestion by Oliver Kiddle.
12753 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
12754 static, to catch errors if the value isn't known at compile-time
12755 and the compiler supports dynamic arrays. Change its name from
12756 `_array_' to `test_array' to avoid potential name clashes.
12757 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
12758 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
12759 better than double. Catch a bug in GCC 2.95.2 x86.
12760 * doc/autoconf.texi (C Compiler): Document the above.
12763 2001-11-13 Akim Demaille <akim@epita.fr>
12765 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
12767 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
12769 2001-11-13 Akim Demaille <akim@epita.fr>
12771 * lib/autotest/general.m4 (AT_INIT): After having run the test
12772 group, go back to the initial directory, not to at_suite_dir.
12774 2001-11-13 Akim Demaille <akim@epita.fr>
12776 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
12777 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
12778 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
12780 (AT_CHECK_CONFIGURE): Use absolute paths.
12781 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
12782 The problem is still the old one: there is no means in M4 (that I
12783 know about) to create a defining macro, because there is no means
12784 to create `$1' etc., therefore, the defining macro ``swallows''
12785 all the arguments meant to the defined macro.
12787 2001-11-13 Akim Demaille <akim@epita.fr>
12789 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
12790 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
12792 * tests/aclocal.m4: Remove, as it is no longer used.
12794 2001-11-13 Akim Demaille <akim@epita.fr>
12796 * lib/autotest/general.m4: Change `tests?' into `groups?' in
12797 variable names when referring to a single test group, or to
12798 `suite' when referring to the whole test suite.
12799 `at_last_test' is removed: m4 compute at_format itself.
12800 (at_stdout, at_stder1, at_stderr): New variables.
12801 (AT_CHECK): Use them.
12803 2001-11-13 Akim Demaille <akim@epita.fr>
12805 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
12807 Create `testsuite.dir/003/run' instead of `testsuite.003'.
12808 Do it as soon as a test fails, don't wait till the end of the test
12810 Don't remove $as_me.[0-9]*, since these files no longer exist.
12812 2001-11-13 Akim Demaille <akim@epita.fr>
12814 * tests/tools.at: Use absolute paths, since we are no longer run
12817 2001-11-13 Akim Demaille <akim@epita.fr>
12819 Now that tests are running in their own private dir, there is no
12820 need to list the files to remove at the end of tests groups.
12822 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
12823 (AT_data_files, at_data_files): Remove.
12824 (AT_CLEANUP, AT_DATA): Simplify.
12826 Remove the group dir if !debug && !failed.
12827 * tests/atspecific.m4: Adjust.
12829 2001-11-13 Akim Demaille <akim@epita.fr>
12831 Start a new layout for Autotest: `testsuite' creates
12832 `testsuite.dir' in which the at-check-line etc. files are to be
12833 found, and `testsuite.dir/003' where the test group 3 is run.
12835 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
12836 at_check_line_file, at_format, at_test_normalized, at_group_dir
12838 Create the directories.
12839 Use absolute paths for at- files.
12840 (AT_CHECK): Adjust.
12842 2001-11-11 Michael Matz <matz@kde.org>
12844 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
12846 (m4_car): Properly quote arguments.
12848 2001-11-13 Akim Demaille <akim@epita.fr>
12850 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
12851 with stricter rules on LIBOBJS.
12853 2001-11-12 Paul Eggert <eggert@twinsun.com>
12855 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
12856 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
12859 2001-11-12 Akim Demaille <akim@epita.fr>
12861 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
12863 2001-11-12 Akim Demaille <akim@epita.fr>
12865 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
12866 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
12867 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12868 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
12869 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
12870 specify to what the macro should be defined (typically to 1).
12872 2001-11-12 Akim Demaille <akim@epita.fr>
12874 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
12877 2001-11-12 Akim Demaille <akim@epita.fr>
12879 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
12880 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
12881 definition used by Automake where LEX is +/- "${missing} lex" and
12882 `missing' itself contains variables.
12884 2001-11-12 Akim Demaille <akim@epita.fr>
12886 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
12887 Now that M4sh pushes BODY, the comments were output at the end of
12890 2001-11-08 Akim Demaille <akim@epita.fr>
12892 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
12893 that we can trace macros from aclocal.m4.
12894 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
12895 obsoleted, and redirect to the former anyway.
12896 Reported by Ralf Corsepius.
12898 2001-11-08 Akim Demaille <akim@epita.fr>
12900 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
12901 processed only if present.
12902 * tests/torture.at (Configuring subdirectories): Use autoreconf
12903 instead of successive calls to autoconf.
12904 Add a nonexistent subdirectory to exercise the patch above.
12905 Reported by Ralf Corsepius.
12907 2001-11-08 Kevin Ryde <user42@zip.com.au>
12909 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
12910 doesn't accept .S files.
12912 2001-11-07 Akim Demaille <akim@epita.fr>
12914 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

12918 (handle_output): Use it.
12919 Read m4_pattern_forbid with messages.
12921 2001-11-05 Akim Demaille <akim@epita.fr>
12923 * bin/autom4te.in (--normalize): Remove.
12924 * lib/autom4te.in: Adjust.
12926 2001-11-05 Akim Demaille <akim@epita.fr>
12928 * tests/Makefile.am (testsuite): Rename this target as...
12929 ($(TESTSUITE)): this.
12932 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
12934 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
12935 the --prefix option, also remove it's argument.
12937 2001-11-05 Akim Demaille <akim@epita.fr>
12939 * doc/autoconf.texi (testsuite Invocation): Update.
12940 (Writing testsuite.at): Update.
12942 2001-11-03 Akim Demaille <akim@epita.fr>

12946 2001-11-03 Akim Demaille <akim@epita.fr>
12948 * lib/Autom4te/General.pm: (&catfile, &canonfile)
12949 (&file_name_is_absolute): New, wrappers around routines from
12951 Use and export them.
12952 (&find_configure_ac): Optionally take a directory where to look at.
12953 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
12955 Default @ARGV to `.', not find_configure_ac.
12956 (&autoreconf): Argument is a directory.
12957 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
12958 * doc/autoconf.texi (autoreconf Invocation): Update.
12960 2001-11-03 Akim Demaille <akim@epita.fr>
12962 * lib/Autom4te/General.pm (@export_vars, @export_subs)
12963 (@export_forward_subs): New.
12964 Add basename, dirname, and fileparse.
12966 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
12967 Don't look for aclocal flags if we already know aclocal is not
12969 Move aclocal.m4t only if it exists.
12970 Reported by Ezra Peisach.
12972 2001-11-03 Akim Demaille <akim@epita.fr>
12974 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
12975 passed on command line, defaulting to ./configure.ac if present.
12976 (&maybe_autoreconf, File::Find): Remove, unused.
12977 (&autoreconf): If autoconf is not used, don't try to trace.
12979 2001-11-02 Akim Demaille <akim@epita.fr>
12981 * configure.ac: Bump to 2.52g.
12983 2001-11-02 Akim Demaille <akim@epita.fr>
12987 2001-11-02 Akim Demaille <akim@epita.fr>
12989 * config/config.guess, config/config.sub, doc/standards.texi:
12990 * config/lispdir.m4: Update from masters.
12991 * configure.ac: Bump to 2.52f.
12993 2001-11-02 Akim Demaille <akim@epita.fr>

12996 Don't run aclocal when aclocal.m4 is not from aclocal.
12998 Don't run libtoolize and gettextize if --install is not given.
13000 2001-11-01 Paul Eggert <eggert@twinsun.com>
13002 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13003 be invoked before _AS_LINENO_PREPARE.
13004 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13005 than character ranges.
13007 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13008 invoking AS_BASENAME. Set the locale variables to 'C' if
13009 possible, as POSIX requires this to get the traditional
13011 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13013 2001-10-31 Paul Eggert <eggert@twinsun.com>
13015 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13016 with {}, as that triggers a bug in Bash 2.05.
13018 (_AS_LINENO_PREPARE): Use Sed rather than
13019 Awk. Fix the sed prepass to work even if there are multiple
13020 instances of $LINENO on the same line. Do not substitute for
13021 other variables like $LINENOT. Do not check file dates; such a
13022 check is unreliable on sufficiently fast machines, and removing
13023 the check makes the code simpler and more reliable. Check for
13024 output and chmod failures.
13026 * doc/autoconf.texi (Special Shell Variables): Document
13029 2001-10-31 Akim Demaille <akim@epita.fr>
13031 * tests/Makefile.am (atconfig): Remove this target, Automake
13034 2001-10-31 Akim Demaille <akim@epita.fr>
13036 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13037 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13038 provided, while it is optional.
13039 * configure.ac: Adjust.
13041 2001-10-26 Paul Eggert <eggert@twinsun.com>
13043 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13044 lib/Autom4te/Struct.pm:
13045 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13048 * doc/autoconf.texi (Special Shell Variables): Document some
13049 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13051 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13052 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13053 eval $LINENO is not portable in practice.
13055 2001-10-24 Akim Demaille <akim@epita.fr>
13057 * lib/Autom4te/General.pm (backname): New.
13059 2001-10-24 Akim Demaille <akim@epita.fr>

13067 2.05's use of ANSI quoting in its `set' builtin.
13069 2001-10-22 Paul Eggert <eggert@twinsun.com>
13071 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13072 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13073 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13074 POSIX decided to standardize on the int flavor of strerror_r.
13075 Always do char* test, as there's no reason not to.
13076 Assign to a char* var, to catch strerror_r that returns int*.
13078 * doc/autoconf.texi (Particular Functions):
13079 Document the above changes. Also, document the fact that
13080 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13082 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13084 2001-10-20 Akim Demaille <akim@epita.fr>
13086 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

13091 * lib/Autom4te/General.pm (&update_file): If destination is
13092 unchanged, remove the source.

13094 * bin/autoreconf.in: No longer support --m4dir.
13095 (&autoreconf): Display the full path of the configure.ac we are
13097 Trace it only once.
13098 Be sure to honor --force with gettextize.
13099 Always run aclocal.
13100 * doc/autoconf.texi: Adjust.
13102 2001-10-20 Akim Demaille <akim@epita.fr>
13104 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13106 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13107 `intl' is already present, as it refuses unless --force.
13108 (&parse_args): Use -I, --include instead of the old Autoconf
13110 ($localdir, $autoconf_dir): Remove.
13112 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13114 2001-10-19 Jens Petersen <petersen@redhat.com>
13116 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

13132 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
13134 * bin/autoreconf.in (autoreconf): Display the path to the
13135 configure.ac being studied.
13137 2001-10-18 Paul Eggert <eggert@twinsun.com>
13139 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13140 long, to work around a bug in the HP C compiler version HP92453-01
13143 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13144 (AS_BASENAME_EXPR): New macro.
13145 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13146 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13147 and fall back on 'sed' only if the other two fail. This makes
13148 AS_BASENAME act more like AS_DIRNAME.
13149 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13150 contains white space.
13151 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13152 Use AS_DIRNAME, since I think it's now DOS-friendly.
13153 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
13154 Allow "dirname //FOO" to return either / or //, as POSIX allows

13159 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

13205 bother with $force since...
13206 * lib/Autom4te/General.pm: does.
13208 2001-10-08 Akim Demaille <akim@epita.fr>
13210 * bin/autoreconf.in: Rewrite in Perl.
13211 * configure.ac: Adjust.

13295 empty, and if we can find a shell that does support LINENO,
13296 then set CONFIG_SHELL to that shell and then re-execute
13297 ourselves with CONFIG_SHELL.
13299 2001-10-05 Paul Eggert <eggert@twinsun.com>
13301 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
13302 doesn't exist. Remove *.tmp, as a .tmp file is created during the

13372 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
13373 Don't use nested parenthesization. This patch was originally
13374 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
13375 but somehow it didn't get incorporated then.
13376 * doc/autoconf.texi (Limitations of Usual Tools):

13382 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13383 Check for `expr' arithmetic overflow, and for compilation failure,
13384 and invoke a new argument $4 if either is discovered.
13385 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13386 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
13388 2001-09-28 Akim Demaille <akim@epita.fr>
13390 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

13420 * tests/fortran.at (GNU Fortran 77): there.

13609 * doc/autoconf.texi (Common Shell Constructs): New node,
13610 documenting AS_DIRNAME.
13611 (Limitations of Usual Tools): Refer to it when discussing dirname.
13612 Also, update discussion of POSIX standard to reflect latest draft.
13614 * lib/autoconf/c.m4:
13615 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
13617 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13618 Do not pass a first argument with leading '-'
13619 to expr, by parenthesizing initial integers that might be negative.
13621 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
13622 now merely checks whether it is an error to pass an argument
13625 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
13626 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
13627 whether it is a (compile-time) error to pass an argument to

13645 Add test for AS_BASENAME.
13646 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
13647 added test. It now correctly handles /1/2/3/, returning '3' not ''.
13648 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
13649 * tests/base.at: Fixed the expected responses. The old ones were
13651 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
13652 the documentation claims it should (and how it behaved in 2.13).
13654 2001-09-18 Akim Demaille <akim@epita.fr>
13656 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
13657 the AC_CONFIG_COMMANDS invocation.
13658 This also solves the name clash problems.

13660 * lib/m4sugar/Makefile.am (version.m4): Revamp.
13661 No longer to be shipped.

13665 Use `m4_PACKAGE_STRING'.
13666 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
13667 the only optional argument is the name of the test suite.
13668 Expect `package.m4' to define the package signature.
13669 * lib/autom4te.in (Autotest): Add `package.m4?'.
13670 * tests/Makefile.am (package.m4): New.
13671 * tests/suite.at: ifnames is a victim.

13676 AC_LIBSOURCE, AC_CONFIG_FILES.

13690 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13691 Always include <stdio.h> and <stdlib.h>. Evaluate
13692 the expression in an extra function before these includes. Call
13693 fprintf "%d" only after ensuring the argument is of type 'int'.
13694 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
13696 2001-09-17 Paul Eggert <eggert@twinsun.com>
13698 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
13699 or CFLAGS=-O5. In that case, the linker has a relaxed view of
13700 fatal errors, and AC_CHECK_LIB causes it to include libraries even
13701 when they don't exist.
13703 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
13704 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
13707 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
13708 version with the version used by fileutils 4.1, except use

13754 * lib/autotest/general.m4 (AT_INIT): Create and remove
13755 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

13760 * tests/mktests.sh: Don't output banners for empty test files.

13866 2001-09-05 Akim Demaille <akim@epita.fr>
13868 Be ready to handle filenames as stupid as `dnl.at', for if even
13869 the maintainer is dumb enough to do that...
13871 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
13872 excellence in M4 quotation: consider `__file__' is active.
13874 And BTW, when invoking m4, pass the --include in the right order:

13900 2001-09-05 Akim Demaille <akim@epita.fr>
13902 CVS GNU M4 doesn't like `undefine(undefined)'.
13904 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
13905 New, extracted from main.
13906 Use IO::File wherever possible.
13907 (input.m4): Be constant, use -I instead of hard coding $tmp.
13908 Therefore be a quoted heredoc.
13909 Don't invoke `_au_disable', since ac was not loaded, but just

13935 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
13937 2001-08-31 Akim Demaille <akim@epita.fr>
13939 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
13940 (testsuite Scripts): There is no such thing as `atconfig.in'.
13941 And actually one diagram is missing: test suite runtime.
13943 2001-08-31 Akim Demaille <akim@epita.fr>
13945 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
13948 2001-08-31 Akim Demaille <akim@epita.fr>
13950 * bin/autoupdate.in (@include): `installcheck' revealed the path
13951 to m4sugar was lacking!
13953 2001-08-31 Akim Demaille <akim@epita.fr>
13955 * man/Makefile.am (.x.1): We really have to pass
13956 autom4te_perllibdir.

13966 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
13967 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
13968 Use directly autom4te, not autoconf.
13969 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
13971 2001-08-31 Akim Demaille <akim@epita.fr>

13993 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
13994 (autoheader): Pass --force since the test suite goes too fast for
13996 Adjust to the new autoheader messages.
13998 2001-08-31 Akim Demaille <akim@epita.fr>

14010 Drop AC_MACRODIR dead for real.
14011 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14012 `autoheader: `config.hin' is created'.
14013 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14015 2001-08-31 Akim Demaille <akim@epita.fr>
14017 * bin/autoheader.in: Rewrite in Perl.
14018 * tests/autoheader: Adjust.
14020 2001-08-31 Akim Demaille <akim@epita.fr>
14022 * bin/autoconf.in (--include, -I): New option.
14023 Map --localdir, --autoconf-dir onto it.
14024 Forward autom4te's options instead of interpreting them.
14025 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14026 There is no such envvar since the inception of autom4te.cfg.
14027 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14028 * bin/autoupdate.in: Adjust, and perform more control.

14030 * tests/autoconf: Dittowise.
14032 2001-08-31 Akim Demaille <akim@epita.fr>
14034 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
14035 * bin/autom4te.in (&find_file): Support `FILE?' standing for
14037 Use -e, not -f, since /dev/null for instance is OK.
14038 (&parse_args): Adjust.
14039 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
14041 2001-08-31 Akim Demaille <akim@epita.fr>

14048 * lib/Autom4te/General.pm (&find_peer): Remove.
14049 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14050 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14051 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14052 find the executables for it.
14053 * tests/Makefile.am: Major cleanup. Too lazy to document...
14054 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14056 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14057 indeed related to running the test suite, while passing
14058 --autoconf-dir and others is related to running non installed
14059 Autoconf executables. So don't do that, leave it to...
14060 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14061 * tests/autoscan: New.
14062 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

14067 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

14078 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
14079 Suggested by Paul Eggert.
14081 2001-08-29 Akim Demaille <akim@epita.fr>
14083 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
14084 download in a tmp dir.
14086 2001-08-29 Akim Demaille <akim@epita.fr>
14088 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

14108 foo=`(command) 2>/dev/null`

14259 the name of the directory they're in, instead of the filename,

14348 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
14349 * NEWS, README, README-alpha, TODO, tests/README: This package is
14350 `Autoconf', not `autoconf' (the executable).
14352 2001-08-20 Akim Demaille <akim@epita.fr>
14354 Info readers seem to need `Index' in the index node title :(
14356 * doc/autoconf.texi: Reverse the 2001-08-15 change which

14406 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
14407 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

14470 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
14471 `$0.log' as for projects where testsuite is in src, we'd have

14476 * bin/autom4te.in (&parse_args): Recognize --normalize.

14488 * doc/autoconf.texi: Work around Texinfo buglets.
14489 (Transformation Rules): One example is enough, users are expected
14490 to have their brains on. And BTW, use DESTDIR.
14491 (dvar): New macro. Use it.
14493 2001-08-17 Akim Demaille <akim@epita.fr>
14495 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

14538 2001-08-15 Akim Demaille <akim@epita.fr>
14540 * Makefile.maint (CVS): New.
14541 (local-check): Run changelog-check. last.

14548 autom4te.cache (it's a directory, not a file.
14549 * Makefile.am: Ditto (but maintainer-clean-local).
14551 2001-08-15 Akim Demaille <akim@epita.fr>
14553 * bin/autom4te.in (@m4_warning): New.
14554 (&handle_m4): Use it.
14555 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
14556 warnings are issued at each run.
14557 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
14558 is in the src tree.
14560 2001-08-15 Akim Demaille <akim@epita.fr>
14562 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
14563 don't waste time running `autoupdate --version' works.
14564 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
14566 2001-08-13 Akim Demaille <akim@epita.fr>

14625 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
14627 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
14628 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
14629 * doc/autoconf.texi (C Compiler Characteristics): Update
14630 documentation for AC_C_BIGENDIAN.
14632 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>

14635 magic values from an object file when cross-compiling.
14636 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
14638 2001-08-10 Akim Demaille <akim@epita.fr>
14640 * bin/autom4te.in (&handle_output): Don't use `grep' with side
14642 Suggested by Russ Allbery.
14644 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
14646 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
14647 current $prefix to the sub-configures.
14649 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
14651 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
14652 extension (needed on BeOS). Reported by Guido van Rossum.
14654 2001-08-09 Akim Demaille <akim@epita.fr>
14656 * bin/autom4te.in ($icache): Load it only if older than autom4te.
14658 2001-08-07 Akim Demaille <akim@epita.fr>
14660 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
14662 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
14663 No need to remove the files before and after the each test, before
14664 each test and at the end of the suite is enough.
14665 Display only the children `times', not the shell's.
14666 If the test failed or was skipped, at-times is not available.
14668 2001-08-07 Akim Demaille <akim@epita.fr>
14670 Always produce testsuite.log, including when there are no
14671 failures. This helps getting information on skipped tests, and
14672 duration of the tests. Err, implement the latter btw.
14674 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
14675 Dump information on the first run of each test.
14676 (AT_CLEANUP): Create `at-times' containing the duration of the
14679 2001-08-07 Akim Demaille <akim@epita.fr>
14681 The use of `dumpstat' revealed that `len' was used although it
14682 should not. m4_text_wrap was using it, but in the Autoconf world
14683 where it is legal. Hence (i) test M4sh in its own world, not
14684 Autoconf's, and (ii), ahem, fix the bug :)
14686 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
14687 does not like `' instead of [].
14688 (AT_INIT): Forbid `^_?AT_'.
14689 And don't output such tokens.
14690 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
14691 `script.as', and `autom4te.cache'.
14692 Remove `empty' and `macro' which are no longer used.
14693 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
14694 * tests/m4sugar.at: Use it.
14695 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
14697 2001-08-07 Akim Demaille <akim@epita.fr>
14699 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
14701 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
14703 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
14705 2001-08-04 Akim Demaille <akim@epita.fr>
14707 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
14708 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
14710 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
14711 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
14712 (AC_F77_MAIN): Likewise.
14714 2001-08-04 Akim Demaille <akim@epita.fr>
14716 Don't rely on M4sugar outputting the patterns in files, since we
14717 might process the output _without_ running m4, hence without these
14720 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
14721 * bin/autom4te.in (@Request::includes): Remove, unused.
14722 (@Request::source): Rename as...
14723 (@Request::input): this.
14724 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
14725 (&handle_output): Fetch the patterns from the traces.
14726 `$forbidden' and `$allowed' are constant: use m//o.
14727 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
14728 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
14730 2001-08-04 Akim Demaille <akim@epita.fr>
14732 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
14733 autoconf', i.e., in addition to caching traces, cache the output.
14735 * bin/autom4te.in (Request::cache): Rename as...
14736 (Request::id): this.
14737 ($cache, $icache, $tcache, $ocache): New.
14738 (&handle_m4): Save M4 output in the cache instead of $tmp.
14739 (&handle_output): Adjust.
14740 (&up_to_date_p): Check that the output cache is up to date too.
14741 (top level): Run `&handle_m4' iff force or the cache is invalid.
14742 Run `&handle_output' if the output cache is more recent.
14744 2001-08-04 Akim Demaille <akim@epita.fr>
14746 * bin/autom4te.in ($force): New.
14747 (&parse_args, &print_usage): -f, --force is a new option.
14748 (&handle_output): CPP directives might have spaces after `#'.
14749 (&parse_args): The first file only can be frozen.
14751 2001-08-04 Akim Demaille <akim@epita.fr>
14753 Don't let autom4te compute the `include' traces several times:
14754 first check that the trace cache file is up to date, and then
14755 compare its timestamp with that of the output.
14757 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
14758 the preamble. Don't require 5.005 as Autom4te::General does it,
14759 and better yet (use `use', not `require'!).
14760 * lib/Autom4te/Struct.pm: Rename the last occurrences of
14761 Class::Struct as Autom4te::Struct.
14762 * lib/Autom4te/General.pm (File::stat): Use it.
14763 (&mtime): New, export it.
14764 * bin/autom4te.in: Use it.
14765 Declare `$req' is invalid if it is outdated.
14766 Don't declare it valid before saving it if something went wrong.
14768 2001-08-04 Akim Demaille <akim@epita.fr>
14770 Autom4te shall not encode Autoconf data, and preselecting traces
14771 must be proposed to the users.
14773 * bin/autom4te.in (@required_trace): Remove.
14775 (&parse_args, &print_usage): -p, --preselect is a new option.
14776 (&up_to_date_p): Adjust.

14781 * tests/tools.at (autoconf --trace: user macros): Check traces on
14782 macros invoked without arguments, and macros invoked with multiple

14792 * bin/autoconf.in ($@): Work around the usual sh bug.
14795 2001-08-03 Akim Demaille <akim@epita.fr>
14797 Clean up the handling of the M4 builtins tracing exception.

14802 (@m4_builtin): this.
14803 (%m4_builtin_alternate_name): New.
14804 (&parse_args): Complete the trace requests with alternate names.

14810 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
14811 m4_if, and m4_wrap.
14813 2001-08-03 Akim Demaille <akim@epita.fr>
14815 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
14816 (m4_divert_pop): Dump the whole diversion stack when a diversion
14818 * bin/autom4te.in (&handle_output): Remember of the first
14819 occurrence of a possibly undefined macro, not the last.
