547 Don't infloop upon "make dist".
548 * GNUmakefile: Merge from coreutils.
549 * Makefile.am (dist-hook): Inject .tarball-version into tarball,

554 2008-03-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
556 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
557 Before using /dev/full, check that it is a writable character
559 Report by Benoit Sigoure and Eric Blake.
561 Actually test that @configure_input@ is expanded correctly.
562 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
563 Actually check generated file contents for the name of the
564 generated file, using AC_PROG_FGREP and $FGREP.

572 (autotools and whitespace in file names): Use them.
573 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
574 Cover more potentially problemtic file names. Use the new
577 Properly handle funny file names for headers in config.status.
578 The test suite did not cover this bug because the code was not
579 quoting properly the arguments of `rm -f' (which "fails" silently)
580 as well as the arguments of `diff' (whose output was redirected to
581 /dev/null so we couldn't see its error message).
582 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
583 file names passed to `rm' and `diff'.
584 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

687 Document grep peculiarity.
688 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Document
689 BSD behavior on binary input.
691 Minor testsuite improvements.
692 * lib/autotest/general.m4 (AT_INIT) <PREPARE_TESTS>: Use fewer
693 forks when sanitizing PATH. Always output machine information,
694 not just when atconfig was located.
696 Add 'testsuite -C dir'.
697 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
699 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
701 <DEFAULTS>: Delay computation of variables based on $at_dir...
702 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
703 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
704 <PARSE_ARGS>: Parse new option.
705 <HELP_TUNING>: Document it.
706 * tests/autotest.at (Choosing where testsuite is run): New test

715 build-aux/texinfo.tex: Sync from gnulib.
716 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:

721 * doc/autoconf.texi (Particular Programs): Do not mention the
722 Autoconf version in which the AC_PROG_INSTALL change was done.
723 Suggested by Paul Eggert.
725 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
727 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
728 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
729 mode, we change to the source directory, also set $ac_pwd so we
730 do not go back to the build tree for the next config subdir.

766 check_SCRIPTS. Building the wrappers for `all' allows help2man
767 to use them for the manpages.
768 Report by Benoit Sigoure.
770 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.

790 font-lock. Create $TMPDIR before it might be used.
792 Fix spurious testsuite failure with M4 1.4.11.
793 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.

798 (m4_require): Avoid extra macro calls.
800 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
802 * tests/torture.at (srcdir): Fix quoting.
804 Do not pass top_srcdir to configure scripts in testsuite.
805 * tests/autotest.at (srcdir propagation): Copy install-sh to
807 (my only test): Drop setting of `top_srcdir'.
808 * tests/base.at (Input/Output): Likewise.
809 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
810 config.guess, and config.sub to test source tree.
811 Drop AC_CONFIG_AUX_DIR setting.
812 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
813 * tests/torture.at (Substitute a 2000-byte string): Drop
814 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
815 (Substitute a newline, datarootdir workaround): Likewise.
816 (Define a newline): Adjust for linenumber changes in configure.ac.
817 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
819 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
820 if `pwd` contains whitespace.
822 Quote $abs_top_srcdir in tests.
823 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
824 * tests/tools.at (Syntax of the shell scripts): Likewise.
826 * tests/m4sh.at (LINENO): Quote $0.
828 Fix testsuite program wrapper for whitespace in `pwd`.
829 The problem here is that the usual mantra is that command
830 variables can contain arguments, thus we cannot just escape
831 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
832 $top_builddir/tests directory early in $PATH, so that the
833 wrappers are found by their plain name.
834 * tests/wrapper.as: Put $testdir early in $PATH.
835 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
837 Proper config.status --file/--header and $srcdir escaping.

845 Fix Autotest for whitespace in `pwd`.
846 * lib/autotest/general.m4 (AT_INIT)
847 <at_func_create_debugging_script, Driver Loop>:
849 * tests/autotest.at (whitespace in absolute testdir): New test.
851 * lib/autom4te.in: Quote @datadir@.
853 Proper file name escaping in Autoconf programs and Perl modules.
854 This includes escaping of characters special to the shell
855 as well as special to Perl, e.g., leading `<' or `>'.
856 For example, when $file starts with `>', `open ">$file"'
857 wrongly tries to append to a different file.
858 * bin/autoconf.as: Fix quoting for autom4te options.
859 * lib/Autom4te/General.pm (shell_quote): New function, taken
860 from coreutils, written by Jim Meyering.
862 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
864 * bin/autoreconf.in (parse_args): Likewise.
865 * bin/autoscan.in (main): Likewise.
866 * bin/autoupdate.in (main): Likewise.
867 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
868 * bin/ifnames.in: Likewise, XFile usage fixes.
869 * tests/tools.at (autom4te and whitespace in file names): Extend
870 test. Test twice, with special characters allowed on w32, and the
871 rest. Test leading and trailing whitespace, for `open_quote'.
872 (autotools and whitespace in file names): New, analogous test.
873 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
874 by Russ Allbery and Eric Blake.
877 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
878 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
879 * lib/Autom4te/FileUtils.pm (open_quote): New function.
880 (update_file, contents): Use it.
882 * Makefile.am (autom4te-update): Rewrite for git.
884 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
886 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
889 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
890 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
892 2007-12-04 Eric Blake <ebb9@byu.net>
894 Manually resync with gnulib, since 'make cvs-update' no longer works.
895 * build-aux/config.guess: New upstream version.
896 * build-aux/config.sub: Likewise.
898 When using older automake, don't downgrade build-aux/texinfo.tex.
899 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
900 * doc/Makefile.am (TEXINFO_TEX): Add.
902 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
904 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
905 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
906 #undef as this runs afoul of our new way of creating config.h.
907 Problem reported by Jim Meyering in
908 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
910 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
912 Fix autom4te for unusual characters in input file names.
913 * bin/autom4te.in (files_to_options): Quote active characters
915 * tests/tools.at (autom4te and white space in file names):
918 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
919 Document that Tru64 awk always splits $0.
921 2007-11-24 Stepan Kasal <kasal@ucw.cz>
923 * lib/autotest/general.m4 (AT_INIT): Do not extract the
924 `#AT_STOP_...' line at the end of each test.
926 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
928 * lib/autotest/general.m4 (AT_INIT): For awk line number
929 extraction script, ensure `$at_group' has a defined value
930 even for the empty set, and properly quote its usage inside
933 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
935 * doc/autoconf.texi (Shell Functions): New chapter. Document
936 IRIX sh $0 issue in functions, move content from ...
937 (Portable Shell): ... here.
938 (Shell Script Compiler): Note that shell functions are not
939 totally unportable any more.
941 2007-11-22 Stepan Kasal <kasal@ucw.cz>
942 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
944 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
945 extracting the line numbers of the last needed test.
947 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
949 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
952 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
954 Fix IRIX testsuite debugging failures: $0 in functions.
955 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
956 Do not use $0 inside a function, as IRIX sh will set that to the
957 function name rather than the script invocation name.
959 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
960 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
962 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
963 to extract test scripts.
964 (AT_INIT): Extract and cache test script line numbers.
966 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
968 * lib/autotest/general.m4: Revert 2007-11-15 patch and
969 subsequent fixups; the awk -> here-document conversion trashes
970 performance too much with AIX sh.
972 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
974 * tests/local.at: Do not test m4, perl with AT_TESTED.
976 Diagnose and guard against write errors dealing with config.status.
977 The general idea is this: all write failures from `configure'
978 writing `config.status' are indicated by $ac_write_error, which
979 is only checked at the end. This is safe because config.status
980 code is not executed before the file is complete. Other write
981 failures, be they inside config.status, or in sub shell/awk
982 scripts spawned from configure or config.status, typically need
983 earlier checking, as their results are used right afterwards.
984 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
985 before writing config.status, check afterwards.
986 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
987 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
988 Set `ac_write_error' for write failures to config.status. Barf
989 upon write failures to temporary files.
990 Adjust note about closing and reopening the here-document.
991 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
992 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
993 reopening the here-document.
994 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
995 Ensure `ac_write_error' does not escape into config.status.
996 Also, add a couple of code paths not yet exercised in the test
997 suite: a config file with input from stdin, and a config header
999 Suggestion for catching write errors by Bruno Haible.
1001 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1003 Avoid error with Tru64 awk and testsuite lines with many words.
1004 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1005 reads the testsuite, set the field separator to an unusual value,
1006 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1007 even splits the input if $i, i>0, was never accessed in the script.
1009 Revert 2007-10-17 change.
1010 * TODO: Multiline args in config files and headers mean something
1011 different and are not fixed, see
1012 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>

1019 AC_*_TOOL does not canonicalize the prefix
1020 * doc/autoconf.texi (Generic Programs): Do not say that

1025 Diagnose write errors in config.status instantiations.
1026 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
1027 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
1029 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

1060 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
1062 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
1065 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1067 * lib/autoconf/status.m4: Fix a couple of comment typos.
1069 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1071 2007-11-13 Jim Meyering <meyering@redhat.com>
1073 Clean up the rule to create "expr".
1074 * tests/Makefile.am (expr): Don't redirect directly to target.
1075 Redirect just once, not for each echo statement.
1076 Use $@, not literal "expr".
1078 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1080 Don't worry about preprocessor when testing long long.
1081 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1082 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1083 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1084 These no longer check for preprocessor flaws.
1085 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1086 Do not check for preprocessor flaws.
1088 2007-11-13 Jim Meyering <meyering@redhat.com>
1090 Adapt dependencies, now that a version change doesn't modify configure.ac
1091 * GNUmakefile: Remove "make clean" kludge.
1092 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1094 Don't redirect directly to target.
1095 Use $@, not literal "version.m4".
1097 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1099 * doc/autoconf.texi (Making testsuite Scripts): Document
1100 ":;{" shorthand as in previous patch.
1102 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1104 * doc/autoconf.texi (Limitations of Builtins): Document problem
1105 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1107 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1108 Use ":;{" shorthand.
1109 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1111 2007-11-12 Jim Meyering <meyering@redhat.com>
1113 Add more non-srcdir build support.
1114 * GNUmakefile (dummy): Split a long line.
1115 Add -v option to autoreconf invocation.
1117 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1118 * GNUmakefile (dummy): Remove INSTALL.
1120 Remove racy commands to build scripts in bin/ and tests/.
1121 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1122 are guaranteed to be built, remove the rules that tried to build
1123 them. Before, with a parallel build, these rules could lead to
1124 two processes writing tests/wrapper.in concurrently.
1126 Build in man/ only *after* building in bin/ and tests/.
1127 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1128 in both bin/ and tests/.
1130 Accommodate non-srcdir build-from-checkout.
1131 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1132 Use git's --git-dir=$srcdir/.git option.
1133 Add quotes, in case tarball_version_file contains shell meta-characters.
1134 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1135 * configure.ac: Pass "." to git-version-gen.
1137 Avoid spurious test failures due to version skew.
1138 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1140 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1142 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1143 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1144 Remove conftest.dSYM directory.
1145 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1146 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1147 Remove `conftest.*' recursively.
1148 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
1149 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1151 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
1153 Report and analysis by Jeff Squyres and Peter O'Gorman.
1155 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
1157 Fix typos in variable names.
1158 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
1160 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
1162 Document that $((expression)) is not portable.
1163 * doc/autoconf.texi (Shell Substitutions): Here.
1165 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1167 Ignore configure --help* errors due to LINENO-impaired shells.
1168 * tests/torture.at (Configuring subdirectories, Deep Package):
1169 In the --help* tests in read-only trees, make `.' temporarily
1170 writable again for the `stderr' file, and ignore errors due to
1171 the attempt to write configure.lineno.
1172 Report by Patrick Welche.
1174 2007-11-10 Jim Meyering <meyering@redhat.com>
1176 Generate package.m4 in build-dir, not srcdir.
1177 * tests/Makefile.am (package.m4): Adjust target.
1178 Don't redirect directly to $@.
1179 (CLEANFILES): Add package.m4.
1180 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1182 When running $(AUTOTEST), search "." before searching $(srcdir).
1184 Avoid a race condition that would make parallel "distclean" fail.
1185 * tests/Makefile.am (distclean-generic): Replace the default,
1186 automake-provided rule with an identical one, but with an additional
1187 dependency on distclean-local. Simply adding the dependency would
1188 cause automake not to emit the rule at all.
1189 * BUGS: Building with -jN works, now.
1191 Distribute git-version-gen.
1192 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1193 since GNUmakefile is distributed, and requires it for dist* rules.
1195 Remove two more generated files from version control.
1196 * INSTALL: Remove generated file.
1197 * lib/autoscan/autoscan.list: Remove generated file.
1199 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1201 * GNUmakefile (PATH): Remove stray apostrophes; they become
1202 part of PATH, which isn't wanted here.
1204 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1206 New config files output variable `top_build_prefix'.
1207 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1209 * doc/autoconf.texi (Preset Output Variables): Document it.
1211 Report by Bob Friesenhahn.
1213 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1214 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1215 function, to parametrize arithmetic with expr vs. the shell.
1216 Use it where possible.
1217 Suggestion by Benoit Sigoure.
1219 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1221 Adjust the documentation of autotest WRT atlocal.
1222 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1223 when using Automake, to write a rule to produce atlocal, since it's
1224 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1225 distributed, not atconfig.in.
1227 2007-11-04 Eric Blake <ebb9@byu.net>
1229 Update list information.
1230 * README: Mention new autoconf-commit list.
1231 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
1233 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1235 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
1237 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1239 * build-aux/.gitignore: Ignore mkinstalldirs.
1241 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1243 2007-11-03 Jim Meyering <meyering@redhat.com>
1245 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1246 * build-aux/git-version-gen: This syncs from coreutils.
1248 Adjust the build procedure so "make check" works reliably.
1249 * README-hacking: Include an extra step between "make" and
1250 "make check" to ensure that the latter passes.
1252 Use just-built tools, when possible.
1253 * GNUmakefile (PATH): Set and export here, ...
1254 (dummy): ... rather than here.
1256 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1257 and Andreas Schwab <schwab@suse.de>
1259 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
1262 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1264 * configure.ac (AC_PREREQ): Require version 2.60, for
1265 AC_PROG_SED, AC_PROG_GREP.
1267 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
1268 and Jim Meyering <meyering@redhat.com>

1270 and Eric Blake <ebb9@byu.net>
1272 Document a bug in GNU Bash with compound commands and redirections.
1273 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
1274 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
1277 2007-11-03 Eric Blake <ebb9@byu.net>
1279 Support m4 1.4.5 in testsuite.
1280 * tests/torture.at (Define a newline): Exclude line numbers in
1282 Reported by Ralf Wildenhues.
1284 2007-11-03 Jim Meyering <meyering@redhat.com>
1286 Remove automake-provided files from version control.
1287 * build-aux/elisp-comp: Remove file.
1288 * build-aux/install-sh: Remove file.
1289 * build-aux/missing: Remove file.
1290 * build-aux/mdate-sh: Remove file.
1291 * build-aux/.gitignore: New file.
1292 Suggestion from Ralf Wildenhues.
1294 2007-11-03 Eric Blake <ebb9@byu.net>
1296 Adjust version comparison to account for git snapshot numbers.
1297 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
1298 component separator.
1299 * doc/autoconf.texi (Number processing Macros)
1300 <m4_version_compare>: Document this change.
1301 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
1303 2007-10-30 Bruno Haible <bruno@clisp.org>
1305 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1306 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1307 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1308 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1309 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1310 Suggested by Paul Eggert.
1312 2007-10-28 Jim Meyering <meyering@redhat.com>
1314 * README-hacking: Autoconf, Automake, and Perl are required to build.
1315 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1317 2007-10-28 Jim Meyering <meyering@redhat.com>
1319 README-hacking: Recommend running autoreconf -vi.
1320 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1321 so that we use just-built tools when they're available.
1322 Suggestions from Ralf Wildenhues.
1324 2007-10-28 Jim Meyering <meyering@redhat.com>
1326 Make inter-release --version output more useful.
1328 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1329 which indicates that it is built using the 19th change set
1330 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1331 is a prefix of the commit SHA1.
1332 * build-aux/git-version-gen: New file.
1333 * configure.ac: Run it to set the version.
1334 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1335 * Makefile.am (dist-hook): Arrange so that .version appears only
1336 in distribution tarballs, never in a checked-out repository.
1337 * .gitignore: Add .version here, too. Just in case.
1338 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1339 not configure.ac, now that the version number changes automatically.
1341 Ensure that $(VERSION) is up to date for dist-related targets.
1342 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1343 git-version-gen doesn't match $(VERSION), but only for dist targets.
1345 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1347 Fix `Deep Package' failure with a configure script early in PATH

1377 problem reported by Bruno Haible in
1378 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
1380 2007-10-22 Eric Blake <ebb9@byu.net>
1382 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
1385 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1387 Don't check for bug in HP-UX 11.00 cpp.
1388 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
1389 Use -1ull rather than -1u, since that causes problems with gnulib; see
1390 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

1408 escaping of backslash in here-documents.
1410 Fix `Deep Package' test failure on FreeBSD.

1412 unnecessarily. Do not try running `/bin/sh configure' with a
1413 configure script to be found in $PATH, if the shell does not do
1414 this resolution. Fixes test failure on FreeBSD.
1416 Fix config header generation with AIX awk.
1417 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
1418 script, use helper array D_is_set, as `" 0"' does not evaluate
1419 to true for AIX awk.

1456 * lib/autotest/general.m4 (BANNERS): New named diversion.
1457 (TESTS_END): Diversion no longer used.
1458 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
1459 shell function, which prints only as needed, using an associative
1460 array of banner text from a special diversion.
1461 <PARSE_ARGS_END>: No longer need awk to find banners.
1462 <TESTS>: Banners are no longer processed by main driver loop, so
1463 we no longer need case statement.
1464 (AT_BANNER): Rewrite to populate new diversion.
1465 (AT_SETUP): Each test invokes its own banner. No output is needed
1466 to the TESTS diversion.

1493 duplication bug by using new macro.
1494 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
1495 programs with stdin redirected, so programs that don't
1496 understand --version won't try to behave interactively.
1497 * tests/autotest.at (Tested programs): Catch this bug.
1498 * tests/m4sugar.at (m4@&t@_append): Test new macro.

2582 * doc/autoconf.texi (Particular Programs): Typo
2583 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.

2587 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
2588 'configure' will fail if the shell lacks proper support for shell
2589 functions. Suggested by RMS.
2591 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
2593 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
2594 about Solaris /bin/printf '%010000x' 123. Problem reported by
2597 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
2599 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
2600 for a.* when searching for executables, as this prevents users
2601 from having files like a.c. Problem reported by Ralf Wildenhues in:

2613 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
2614 AC_CHECK_TYPE, AC_CHECK_TYPES.
2615 * doc/autoconf.texi (Generic types): C types must be type-names
2616 (the C terminology), not type-ids (the C++ term). C++ types
2617 must not be anonymous.
2618 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
2619 for C++; this drops support for anonymous struct and union types,
2620 which were problematic anyway.

2639 with objects too. Document the restrictions on its use.
2640 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
2641 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
2642 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
2643 works but the latter doesn't, then it's a valid type.
2644 This lets people use function types and so forth.
2645 For C++ there doesn't seem to be a simple solution, so leave it alone.
2646 (AC_CHECK_SIZEOF): Allow argument to be a variable.
2647 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
2648 AC_CHECK_TYPE; that wasn't documented or necessary.
2650 2007-04-11 Stepan Kasal <kasal@ucw.cz>

2705 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
2706 (Limitations of Usual Tools): Also list \< and \>, and mention that

2818 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
2819 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
2820 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
2821 substitution will still be done by the special code.

2845 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
2846 early on the reader side, drop stderr of the input to avoid
2847 `broken pipe' error output; this may happen even with shell
2848 builtin `echo' of some bash versions. Reports by Ian Macdonald

2866 discussion about the allow_superuser_privileges example,
2867 and change it a bit to make things clearer.
2868 (Optimization and Wraparound): Clarify whether the compiler
2869 will generate an infinite loop for the example derived from
2870 Autoconf's mktime test.
2871 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
2872 Also, clarify unsigned multiplication overflow.
2874 2007-01-04 Eric Blake <ebb9@byu.net>
2876 * bin/Makefile.am (RELEASE_YEAR): New macro.

2888 * doc/autoconf.texi (Integer Overflow): Revised based on today's
2889 feedback. The most important changes document what happens when
2890 you convert an out-of-range value to a signed integer type, and
2891 say that (sum < a) != (b < 0) reliably detects overflow when sum =
2894 * doc/autoconf.texi (Integer Overflow): Greatly expand and
2895 rewrite, taking notions from the recent discussion on the gcc and
2896 autoconf mailing lists; please see
2897 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
2898 and follow the many links.
2899 (Integer Overflow Basics, Signed Overflow Examples):

2901 (Signed Integer Division): New sections.
2903 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
2905 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
2906 preprocessor macro arguments in traced name.
2907 * doc/autoconf.texi (Defining symbols): Document longstanding
2908 support for AC_DEFINE-ing macros with arguments, and document
2909 behavior when the same variable has multiple AC_DEFINEs.
2910 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
2911 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
2912 macros directly, giving much shorter and simpler code.
2914 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
2916 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
2917 space before "$ac_configure_args" to prevent a 'config.status
2918 --recheck' failure if ac_configure_args doesn't contain a leading
2919 space. This works around a problem with the XEmacs configure.ac,
2920 which uses the (undocumented) ac_configure_args variable
2921 inconsistently with Autoconf.
2923 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
2925 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
2926 Include <limits.h>, and use its INT_MAX to rewrite the
2927 j loop so that it does not overflow 'int'. Problem reported by
2929 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
2930 Play it safe by shifting left by 1 rather than multiplying by 2,
2931 as GCC is less likely to optimize this away when the value
2932 is signed (when it assumes overflow leads to undefined behavior).
2933 Also, don't assume time_t uses two's complement.
2935 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2937 * tests/torture.at (Substitute a 2000-byte string): Avoid using
2938 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
2939 dumps core on it. Report by Tim Rice.

2957 (Configure Option Checking). Tighten up the wording a bit.
2958 (External Software, Package Options): Cross-reference to Option
2959 Checking, and use this to shorten our section.
2960 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
2961 "$x" to test "x$foo" != x.
2962 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
2963 Don't warn if $enable_option_checking is "no".
2964 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
2965 ac_unrecognized_opts to the empty string.
2966 Don't echo the unrecognized opts, as this might mishandle
2967 backslashes or leading -.

2969 usage next to the other --disable-FEATURE options in the

2974 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):

2976 Print warning for unrecognized --with and --enable options
2977 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
2978 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
2979 Disable option checking when subdirs are configured.
2980 (AC_OUTPUT): If warnings are enabled, print warning about
2981 unrecognized --with and --enable options at the end of
2982 the configure output (as well as at the beginning).
2983 * doc/autoconf.texi (Option Checking): New node.
2984 Document new option warning functionality.
2986 2006-12-16 Eric Blake <ebb9@byu.net>

2993 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2994 Define HAVE_GETMNTENT to 1, not to the empty string.
2995 Problem originally reported by Jochen Friedrich in
2996 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
2998 This change prompted by a problem report by Andrey Simonenko in
2999 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3000 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3001 object-like macros only, in the traditional portable character
3003 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3004 Warn about attempts to define things that are not identifiers.
3005 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3006 awful hack that AC_DEFINEd macro names containing parentheses.
3008 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3010 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3011 too drastic, even if Texinfo in theory requires it for info mode.
3013 (config.status Invocation): Renamed back from Recreating a
3015 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3016 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.

3025 * NEWS: Document changes with echo and printf, and the lack
3026 of limits on the total size of multi-line values of substituted
3027 variables, and the AC_FUNC_FSEEKO fix.
3029 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3031 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3032 Writing configure.ac.
3033 (Autoconf Input Layout): Renamed from configure.ac Layout.
3034 (Recreating a Configuration): Renamed from config.status Invocation.
3035 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3036 (acconfig Header): Renamed from acconfig.h.
3037 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3038 (Writing Testsuites): Renamed from Writing testsuite.at.
3039 (Autom4te Cache): Renamed from autom4te.cache.
3041 * BUGS: Remove mention of VPATH problem, since it's now documented
3042 not to be a bug in the Autoconf build procedure itself, but rather
3043 a problem with the proprietary `make' programs.
3045 * doc/autoconf.texi (Build Directories): Add a cross reference
3048 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3049 * doc/standards.texi: Sync from gnulib.
3051 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3052 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3053 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3054 generated automatically.
3056 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3058 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3059 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3060 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3062 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3064 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3065 `CEOF$ac_eof' special marker, the awk script cannot contain a
3066 line matching `^CEOF', so this is not needed any more.
3067 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3068 special marker in the test.
3070 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3072 * tests/tools.at (autom4te preselections): Use `find -newer';
3073 remove one of the sleeps.
3075 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3076 more readable, using ...
3077 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3079 * doc/autoconf.texi (autoheader Invocation): Do not double-
3080 quote the parameter of `AH_BOTTOM' in the example.
3082 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3084 * doc/autoconf.texi (Configuration Headers): Remove the
3085 example with multiple input files.
3086 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3087 multiple input files.
3089 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3091 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3092 creating the awk substitution script, handle one input line at a
3093 time, so that the maximum length of a substituted (multi-line)
3094 value is not limited by the size of the sed pattern space.
3095 The trade-off is a slightly repetitive sed script.
3096 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3097 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3098 * tests/torture.at (Substitute a 2000-byte string): Increase the
3099 test with several long lines, they should not be caught by sed
3102 * tests/tools.at (autom4te preselections): New test, to flag
3103 entries missing from autom4te.cfg.
3104 Report by David Byron <dbyron@hheld.com>.
3106 * tests/torture.at (Substitute a 2000-byte string): Actually use
3107 AC_PROG_AWK, so the last change works as intended.
3108 (Substitute and define special characters): Likewise.
3109 (Substitute a newline): Likewise.
3111 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3112 instead of `awk' consistently.
3113 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3114 * tests/torture.at (Torturing config.status): Test both the
3115 result of AC_PROG_AWK and plain awk.
3116 (Substitute a 2000-byte string): Likewise.
3117 (Substitute and define special characters): Likewise.
3118 (Substitute a newline): Likewise.
3120 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3122 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3123 can be assigned to a function pointer. Problem reported by
3124 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3125 part of a patch by Ralf Wildenhues in that same bug report.
3127 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3129 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3130 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3132 2006-12-01 Eric Blake <ebb9@byu.net>
3134 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3135 cross-compiling from cygwin to mingw.
3136 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3137 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3138 to lib/autoconf/c.m4.
3140 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3142 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3143 string for more reliable failure. Wrap the entire test that
3144 causes the broken Solaris printf to dump core, in a subshell,
3145 so the segmentation fault message is reliably suppressed.
3146 Fix shell expansion errors by using /usr/ucb/echo always;
3147 avoid an error on systems without it by another subshell.
3148 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3149 subshell-$as_echo to `as_echo', for better error message.
3151 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3153 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3154 `BASH_SOURCE' contain a newline, set them to empty, as they may
3157 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3159 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3160 years and is too hard to maintain now. The last straw was
3161 reported by Jerker Baeck in
3162 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3163 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3164 * doc/autoconf.texi (Particular Functions): Move
3165 AC_FUNC_SETVBUF_REVERSED from here...
3166 (Obsolete Macros): ... to here. Say that it does nothing now.
3167 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3168 Turn into (almost) a no-op.
3170 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3172 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3173 These macros are obsolescent and new applications shouldn't need them.
3174 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3175 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3176 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3177 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3178 (AC_FUNC_VPRINTF): Likewise.
3179 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3180 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3181 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3183 * doc/autoconf.texi (Setting Output Variables): Mention that
3184 @VAR1@VAR2 has unspecified behavior. Problem reported by
3186 * NEWS: Mention this.
3188 * Makefile.am: Put only a single '#' into the copyright notice,
3189 so that it's also present in the output file. Standardize wording
3190 in makefile copyright notices to match GNU coding standards.
3191 * bin/Makefile.am: Likewise.
3192 * doc/Makefile.am: Likewise.
3193 * lib/Makefile.am: Likewise.
3194 * lib/freeze.mk: Likewise.
3195 * lib/autoconf/Makefile.am: Likewise.
3196 * lib/autoscan/Makefile.am: Likewise.
3197 * lib/autotest/Makefile.am: Likewise.
3198 * lib/m4sugar/Makefile.am: Likewise.
3199 * man/Makefile.am: Likewise.
3200 * tests/Makefile.am: Likewise.
3201 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
3204 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3206 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3207 in the sed script that mangles the awk script: delete up to the
3208 first exclamation mark only.
3209 * tests/torture.at (Substitute and define special characters):
3212 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3214 Rewrite config files generation: avoid quadratic growth in
3215 the number of substituted variables by using awk instead of sed
3216 for the bulk of the substitutions.
3217 * NEWS: Mention this.
3218 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3219 forbidden in the output (and thus input) file.
3220 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3221 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3222 generate just one large awk script for substitutions,
3223 eliminating much of the earlier complexity, while adding some
3224 new complexity. Only expand the substitution templates at
3225 configure time, for smaller configure script size. If
3226 _AC_SUBST_FILES are used, test 'awk' for working getline support
3227 at config.status time. If absent, interpolate through the
3228 shell. The awk script was written with much help
3229 from Paolo Bonzini and Paul Eggert.
3230 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3231 (_AC_SED_FRAG_NUM): Likewise.
3232 (_AC_SUBST_CMDS): Renamed from...
3233 (_AC_SED_CMDS): ...this.
3234 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3235 * tests/torture.at (Substitute a 2000-byte string): Also
3236 substitute a line with 1000 words, and a variable with several
3238 (Substitute and define special characters): Test awk special
3239 characters, and put substitution input strings `@foo@' in the
3240 output, to test that no recursion happens; test several other
3241 combinations from Paolo Bonzini.
3243 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3245 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3246 that replaced echo with AS_ECHO where this wasn't necessary.
3247 Problem reportd by Ralf Wildenhues.
3248 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3249 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3250 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3252 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3254 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3256 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3258 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3259 that traditional Awk lacks 3-arg "split". It has it.
3260 Mention that FS must be a single character, and a few other
3261 99-byte limits of traditional Awk.
3262 Mention that if (i in a) doesn't work with traditional Awk.
3264 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3266 * tests/autotest.at (BSx641-newline in command):
3267 (BS-BS-newline in command, BSx640-newline in command):
3268 (Newline-CODE-BS-newline in command):
3269 (Single-quote-BS-newline in command):
3270 (Single-quote-newline-BS-newline in command):
3271 Use printf '%s\n' instead of echo, for portability to hosts
3272 where echo interprets backslashes. This will break on hosts
3273 that lack printf, but for now let's assume all such hosts
3274 are dead (if not, we should get reports of test failures).
3276 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3278 'echo' has some portability problems, when given a first argument
3279 with a leading '-', or when given any argument containing '\'.
3280 Avoid using 'echo' in these cases.
3281 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
3282 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
3283 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3284 * lib/autotest/general.m4 (AT_INIT): Likewise.
3285 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
3286 argument might be unportable.
3287 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
3288 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
3289 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
3290 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
3291 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
3292 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
3293 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
3294 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
3295 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
3296 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
3297 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
3298 (AC_PROG_MAKE_SET): Likewise.
3299 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
3300 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
3301 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
3302 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
3303 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
3304 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
3305 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3306 * bin/autoconf.as: Redo verbose flag implementation, as the old
3307 scheme wouldn't work with AS_ECHO.
3308 * lib/autotest/general.m4 (AT_INIT): Likewise.
3309 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3310 Don't use ECHO_T, since ECHO_N is now reliable.
3311 * lib/autotest/general.m4 (AT_INIT): Likewise.
3312 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3313 rather than using a here-document to put the script into a file.
3314 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3316 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3317 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3318 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3319 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3320 * lib/autotest/general.m4 (AT_SETUP): Likewise.
3321 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
3322 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3323 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3324 operand, as AS_ECHO requires. Avoid double file name expansion.
3325 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3326 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3327 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3328 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3329 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3330 Double-quote strings that would otherwise contain M4 comments.
3331 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3333 * configure.ac (AC_INIT): Bump to 2.61a.
3336 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3340 * configure.ac (AC_INIT): Bump to 2.61.
3343 * tests/autotest.at (Macro with backslash in a test title):
3344 Comment out for now, as this tests neither fails nor passes
3345 reliably. Problem reported by Ralf Wildenhues.
3347 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3349 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
3350 in previous change, which caused test failures.
3352 2006-11-16 Stepan Kasal <kasal@ucw.cz>
3354 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
3355 code for --enable, --disable, --with, and --without to...
3356 (_AC_INIT_PARSE_ENABLE): ... a new macro.
3357 * doc/autoconf.texi (Package Options):
3358 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
3360 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3362 Import these changes from config via gnulib:

3419 first argument may also contain dots.
3421 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
3423 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
3424 benefit of platforms like Solaris+GCC where it is common to have a
3425 non-working g++ installation.
3427 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3428 and Joel E. Denny <jdenny@ces.clemson.edu>
3429 and Paul Eggert <eggert@cs.ucla.edu>

3432 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
3435 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3437 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
3438 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
3439 Imported from a similar patch to gnulib by Bruno Haible.
3441 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3443 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
3444 * doc/autoconf.texi (C Compiler): Document them.
3445 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
3446 New macros, taken from gnulib.
3448 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>
3450 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Detect bug in

3454 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3456 * tests/torture.at (Configuring subdirectories): Do not skip
3457 Automake 1.10 nor future Automake 11.1 (sic).
3459 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
3460 and Stepan Kasal <kasal@ucw.cz>
3462 Handle special characters in test case titles correctly.
3463 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
3465 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
3466 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
3467 argument. Extend to check titles printed by ./micro-suite and
3468 ./micro-suite -l and the title in micro-suite.log.
3469 (Backquote in a test title,
3470 Single-quote in a test title,
3471 Double-quote in a test title): Don't expect failure anymore.
3472 (Backslash in a test title): Put a non-whitespace character after the
3473 backslash so that Bourne shells might actually see it as an escape
3475 (Brackets in a test title,
3476 Pound in a test title,
3477 Comma in a test title,
3478 Quoted Macro in a test title,

3481 (Macro with backquote in a test title,
3482 Macro with double-quote in a test title,
3483 Macro with backslash in a test title): New tests expected to fail.
3484 * tests/torture.at (#define header templates): M4-quote this title in
3485 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3486 The visible effect was a stray [] in the testsuite output.
3488 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3490 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3491 `trap ... 0' inside a function, for AIX sh.
3493 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3495 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3496 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3497 5363) simply issues a warning when dividing by zero at compile
3498 time. Problem reported by Elias Pipping.
3500 2006-10-26 Eric Blake <ebb9@byu.net>
3503 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3504 show effect on macros that expand with commas.

3529 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
3531 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3532 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3533 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3534 reported by Nelson H. F. Beebe for Coreutils 6.4.
3536 * tests/tools.at (autoconf --trace: user macros): Remove test
3537 for tracing multiline macros, since m4 1.4.7a uses a different
3538 way to number lines. Problem reported by Ralf Wildenhues.
3540 2006-10-24 Stepan Kasal <kasal@ucw.cz>

3565 * doc/autoconf.texi (Caching Results): Likewise.
3566 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
3567 AC_CACHE_CHECK_INT, since it's no longer public.
3568 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
3569 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

3614 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
3616 (Imported from Automake.)
3617 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3618 which incorrectly sets the mode of an existing destination
3619 directory. In some cases the unpatched install-sh could do the
3620 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3621 system. We hope this is rare in practice, but it's clearly worth
3622 fixing. Problem reported by Alex Unleashed in
3623 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3624 Also, don't bother to check for -m bugs unless we're using -m;
3625 suggested by Stepan Kasal.

3647 2006-09-16 Karl Berry <karl@gnu.org>
3648 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
3649 to avoid sectioning errors.

3653 2006-10-04 Karl Berry <karl@gnu.org>
3654 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

3671 2006-10-13 Stepan Kasal <kasal@ucw.cz>
3673 * doc/autoconf.texi (Autoheader Macros): Warn that the text
3674 added to the template can get mangled.
3676 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3678 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
3679 include the default headers, and redefine obstack_chunk_alloc
3680 and obstack_chunk_free. Fixes false failure with glibc.
3682 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
3684 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

3697 the NonStop platform.
3698 * doc/autoconf.texi (Posix Variants): Likewise.
3699 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
3701 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
3702 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
3703 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
3704 Use a better substitute, by inspecting the output of "ls"
3705 rather than just using ":".
3706 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
3707 rather than AS_EXECUTABLE_P, since we needn't worry about
3708 non-regular files here.
3710 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
3711 due to configuration hassles with this. See Tonya Underwood's report
3712 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

3723 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
3724 initialization which is not inherited through the environment
3725 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
3726 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

3731 problems with mkdir -p -m.
3733 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
3735 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
3736 comment about ac_cpp_err; it was incorrect, and anyway
3737 ac_cpp_err is being removed below.
3738 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
3739 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
3740 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
3742 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
3743 with werror_flag and conftest.err and so forth. This is more
3744 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
3745 and anyway the user shouldn't normally want to see this gorp logged.
3746 Problem reported by Ralf Wildenhues.
3747 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
3748 empty, not 'no', since the rest of the code uses 'test -z'.
3750 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
3752 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3753 Use a single call to AC_DO_TOKENS rather than multiple, for
3755 (_AC_LINK_IFELSE): Test that resulting file is executable.
3756 Problem reported by mwoehlke in
3757 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
3759 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
3760 than creating a file to use with test -x; this is much faster.
3762 2006-10-02 Bruno Haible <bruno@clisp.org>
3764 * lib/autom4te.in (Automake-preselections): Add
3765 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
3767 2006-09-27 Stepan Kasal <kasal@ucw.cz>
3769 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
3770 standard error, `experr' should be used, not `expout'.
3772 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
3774 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
3775 fseeko testing program twice; just use the earlier result.
3776 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3777 Set cache var to 'unknown' (not 'no') if leaving the macro unset
3778 still doesn't let the program compile.
3779 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
3782 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
3783 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
3784 include it, without including anything else.
3785 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
3787 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

3791 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
3792 `error.h', and include it, for a `error_at_line' prototype.
3793 Use a nonempty format string in the link test.
3794 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
3795 for a declaration of wait3.

3801 can apply to constants too, and that it checks for macro defns.
3802 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

3804 values. Problem reported by Ralf Wildenhues.

3965 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
3966 except the first two arguments are reversed.
3967 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.

4018 didn't work if some values were cached but not others. Test for
4019 broken lex libraries like native ia64-hp-hpux11.22; see
4020 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4021 work around the problem by preferring an empty LEXLIB to -lfl or
4022 -ll. Let the user set LEXLIB='' to indicate no library needed.

4174 problems with arg script text that doesn't end in newline, and

4252 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4253 more globally, since the 2006-06-30 patch didn't suffice. Problem
4254 reported by Keith Marshall. Also, don't bother with builddir2,
4255 since it shouldn't be needed any more.
4257 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

4278 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4279 Require that long long int be at least 64 bits wide. C99 requires
4280 this and enough programs depend on it so we should check for it.

4294 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4296 * doc/autoconf.texi: Be more consistent about using @acronym with
4297 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4298 quite right (it talked about "OSF/Tru64", even though the
4299 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4300 and it even mentioned "OSF 4"!) and at this point there's little
4301 reason to talk about OSF any more, since it died in 1994.
4302 (Specific Compiler Characteristics): Simplify example of
4303 negative-size array.
4304 (File Descriptors): Reorder to make the text flow better.
4305 Remove joke about "appreciate the various levels"; I didn't get it.

4312 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4314 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4315 -lXt in LIBS, idea from Karsten Hopp; this was due since
4318 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4319 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4320 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4321 (which belong to Xt, not X itself). See Debian bug 327655.
4323 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4325 * configure.ac (AC_INIT): Bump to 2.60a.

4381 * tests/tools.at (autoconf: the empty token): New test.
4383 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4385 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4386 calls, so that we do not care whether they are LIFO or FIFO;
4387 in the m4_wrap, do not check which diversion is the topmost
4388 one, just check that the stack is balanced at the end.
4389 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4390 base diversion forever--pop the previous diversion before
4391 opening the new one; consequently, remove the m4_wrap call.
4392 * lib/autotest/general.m4 (AT_INIT): Likewise.
4393 * tests/m4sugar.at: Do not use
4394 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

4402 care whether it's LIFO or FIFO.
4403 Fix some "contrary to"s that are awkward in English.
4405 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4407 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4408 to `yes' instead of `int$1_t' if the type is found, for more
4409 consistent configure output (where $1 is the number of bits).
4410 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4411 Suggested by Bruno Haible.
4413 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4414 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4415 with system headers. Report by Bruno Haible.
4417 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4419 * config/config.guess, config/config.sub: Sync from upstream.
4421 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4422 in order to avoid picking up an older installed frozen m4sh.m4f.
4423 Besides an outdated shell startup, this could have been created
4424 by an earlier M4 version with incompatible frozen file format.
4426 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4428 * README: Recommend m4 1.4.4 instead of 1.4.3..
4429 * doc/autoconf.texi: Likewise.
4430 (Special Chars in Names): Say that $(.FOO) is portable, as
4431 suggested by Stepan Kasal.
4432 (Installation Directory Variables, Build Directories):
4433 (Automatic Remaking, Subdirectories, Fortran Compiler):
4434 (Making testsuite Scripts, Defining Directories):
4435 Quote variable usages better.
4436 (Making testsuite Scripts): Add clean-local rule to makefile
4437 snippet, by Eric Blake.
4438 (Installation Directory Variables): Fix table item font.
4439 Reword slightly to clarify. Generalize advice about
4440 not using special characters to include all file-related
4441 vars, not just VPATH.
4442 (Special Chars in Variables): Warn about special characters in
4444 (Assignments): Clarify default-value example as suggested by
4446 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4447 (Special Shell Variables): Note leading ./ or ../, as suggested
4449 (Limitations of Builtins): Under cd, warn about CDPATH.
4450 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4453 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4455 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4456 `@var', for texi2html.
4457 (Systemology): Some more word wrapping, for DVI output.
4458 (autom4te Invocation): The short option for `--melt' is `-M',
4461 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4463 * doc/autoconf.texi: More formatting and English tweaks,
4464 many suggested by Ralf Wildenhues.
4465 Reword to avoid "@code{...}'s" and the like, since it's ugly
4466 with Emacs info mode. discontents -> woes.
4467 Put a few "will"s back. time stamp -> timestamp.
4468 side-effect -> side effect.
4470 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4472 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4473 Warn about $@ not persisting. Problem reported by Julien Danjou in
4474 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4475 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4476 Mention other special chars, too.
4478 2006-06-14 Eric Blake <ebb9@byu.net>
4480 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4482 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4484 * doc/autoconf.texi: Some systematic minor improvements, as
4485 follows. Use "makefile" when talking about makefiles
4486 generally (which might be named "makefile" or "Makefile" or even
4487 "foo.mk"), "Makefile" when talking about a specific makefile
4488 called "Makefile". This unclutters the text from weird quotes
4489 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4490 values" rather than "@var{foo}s" and similar constructs containing
4491 "}s". Use "Make rules" rather than "Makefile rules". Minor
4492 English-language improvements. Change the prefix "sub-" to "sub"
4494 Put blank lines around examples more consistently.
4495 Avoid "rather" and "very" as intensifiers.
4496 Avoid "will" as an auxiliary.
4497 (Limitations of Make): Split this node into....
4498 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4499 (Leading _ in Macro Names, Backslash-Newline-Newline):
4500 (Backslash-Newline Comments, Long Lines in Makefiles):
4501 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4502 (obj/ and Make, make -k Status, VPATH and Make):
4503 (VPATH and Double-colon, $< in Explicit Rules):
4504 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4505 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4506 New nodes, resulting from splitup of Limitations of Make.
4507 All cross-references changed. Raise the top node from
4508 a section to a chapter, and all subnodes accordingly.
4509 Redo the introductory wording to match the new organization.
4510 (Installation Directory Variables): Use an example that is
4511 closer to what Autoconf actually does. Mention that VPATH's
4512 value should not contain metacharacters or white space.
4513 (Fortran Compiler): Fix a VPATH bug in an example.
4514 (Leading _ in Macro Names): Mention that this problem is no longer
4515 of practical concern.
4516 (VPATH and Make): Reword the advice to make it clearer
4517 that Autoconf and Automake support VPATH in non-GNU make, but
4518 many packages have bugs in this area.
4519 ($< in Explicit Rules): Refer to Build Directories rather
4520 than using a (non-VPATH-safe) example.
4521 (Automatic Rule Rewriting): Mention the sort of disaster that
4522 can ensue with Solaris-style rule rewriting with VPATH.
4524 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4526 * doc/install.texi (Compilers and Options): Weaken the
4527 suggestion to use GNU make for VPATH builds.
4529 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4530 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4532 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4533 in regular expression.
4535 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4537 * doc/autoconf.texi (Installation Directory Variables):
4538 Drop extra @samp from `@table @samp' item.
4539 (Limitations of Usual Tools): Comment fix.
4540 Do not nest @samp just to point to other table items.
4541 (Writing testsuite.at) <AT_CHECK>: The second argument to
4542 `@dvar' is already @samp'ed.
4543 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4544 do not use @var in the second argument.
4546 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4548 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4549 $as_shell.exe too. Problem reported by Andreas Buening in
4550 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4552 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4554 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4555 `unused variable' compiler warning, for `-Wall -Werror'.
4556 Reported by Jaap Haitsma in
4557 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4559 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4561 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4562 case the compiler dumps core. Problem reported for
4563 OpenServer 5.0.7 by Tim Rice in
4564 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
4565 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4568 2006-06-06 Tim Rice <tim@multitalents.net>.
4570 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4571 "ERROR" only shows up in "make check" output if there is an
4574 2006-06-06 Eric Blake <ebb9@byu.net>
4576 * tests/tools.at (automatically allowed tokens): Fix typo.
4578 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4580 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
4582 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
4583 typically overflows on x86 CPUs, even though the C standard
4586 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4588 * configure.ac (AC_INIT): Bump to 2.59e.
4591 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4595 * config/texinfo.tex: Sync from upstream.
4597 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4598 seen, invoke libtoolize with `--ltdl' argument.
4599 * lib/autom4te.in (Autoreconf-preselections): Adjust.
4601 Suggested by Eric Blake.
4603 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4605 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
4606 reported by Ralf Wildenhues.
4607 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
4609 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4613 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4615 * doc/autoconf.texi: Modernize some of the references to Solaris.
4617 2006-06-05 Stepan Kasal <kasal@ucw.cz>
4619 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
4620 message issued by AC_REQUIRE.
4621 * tests/m4sugar.at: Check m4_require's error message.
4622 * tests/base.at: Check AC_REQUIRE's error message.
4623 * tests/local.at (AT_CHECK_M4): New macro, almost identical
4625 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
4627 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
4628 `expout' as the last parameter.
4629 * tests/tools.at: Adapt to the above change.
4631 2006-06-04 Stepan Kasal <kasal@ucw.cz>
4633 * doc/autoconf.texi (Limitations of Usual Tools): Correct
4634 information about race-free implementations of mkdir.
4636 2006-06-04 Eric Blake <ebb9@byu.net>
4638 * bin/autoreconf.in (help): Document M4 environment variable.
4639 * bin/autoconf.as (Usage): Likewise.
4640 * bin/autom4te.in (help): Likewise.
4641 * doc/autoconf.texi (autom4te Invocation): Likewise.
4643 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
4645 * NEWS: GNU make now recommended for VPATH builds.
4646 Mention that some macros are now documented to be obsolescent.
4647 * doc/autoconf.texi:
4648 Prefer "current" to "modern" to describe
4649 currently-used (albeit perhaps old-fashioned) hosts.
4650 Mention which ancient features no longer need to be worried about.
4651 setgid -> set-group-ID
4652 setuid -> set-user-ID (these are the Posix terms)
4653 Fix some misuses of "only".
4654 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
4655 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
4656 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
4657 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

4661 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
4662 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
4663 Mention that these macros are obsolescent.
4664 (Installation Directory Variables): shall -> should
4665 (File Descriptors): Mention that 0, 1, 2 might get reopened.
4666 Mention that it's now safe to use 3 and 4.
4667 (Limitations of Usual Tools): cp -r is now specified by Posix.
4668 Omit longwinded and obsolescent discussion of cp -f.
4669 Modernize discussion of expr, ls.
4670 (Limitations of Make): Modernize discussion of VPATH builds.
4671 Mention $? as a workaround in some cases.
4672 * doc/install.texi (Basic Installation):
4673 Mention "./configure; make; make install" first. Be more
4674 specific about why this file is generic. Remove unnecessary
4675 parens. Remove misleading "only". Remove obsolete advice
4676 about csh. Don't say "configure" takes awhile; say it
4677 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
4678 and CC=c99 rather than CC=c89, as these are blessed by current
4679 Posix. Recommend GNU make if doing a VPATH build.
4681 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
4683 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
4684 examples involving shell prompts.
4686 2006-06-02 Stepan Kasal <kasal@ucw.cz>
4687 and Paul Eggert <eggert@cs.ucla.edu>
4689 * doc/autoconf.texi (Here-Documents): Add details about the
4690 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
4691 use "here-documents" instead of "here documents".
4693 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4695 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
4697 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
4699 * doc/autoconf.texi (File System Conventions): Warn about ":"
4700 anywhere in directory names.
4702 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
4704 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
4705 about quoting the case statement, just in case.
4706 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
4707 was fixed in ksh93g; reported by Ralf Wildenhues.
4709 2006-05-31 Stepan Kasal <kasal@ucw.cz>
4711 * doc/autoconf.texi (System Services): Do not document
4712 overriding EXEEXT via ac_cv_exeext=ext.
4713 (Particular Programs) <AC_PROG_MKDIR_P>:
4714 Document that ${MKDIR_P} understands --.
4715 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
4718 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4720 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
4721 argument with leading hyphen. Problem reported by Paul Eggert.
4723 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4725 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
4726 about quoting ac_try: quote all of it, if any of it seems suspicious.
4727 This means we don't have to worry about ${ or sed any more.
4728 Also, double-quote the case statement, to work around misuses via
4729 underquoting as reported by Ralf Wildenhues in
4730 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
4731 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
4732 undocumented and dangerous macro.
4733 Problem reported by Ralf Wildenhues in
4734 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
4736 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4738 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
4739 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
4740 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
4742 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4744 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
4745 since evidently some packages rely on the old, broken behavior.
4746 Problem reported by Ralf Wildenhues in
4747 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
4748 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
4749 pre-2006-05-26 definitions, but leave in the comments that
4750 these macros are dangerous and should not be used.
4751 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
4752 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
4753 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
4754 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
4755 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
4757 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4759 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
4760 the use of 'tr', since this is our only use of 'tr'.
4762 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4763 and Paul Eggert <eggert@cs.ucla.edu>
4765 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
4766 Don't assume 'grep' works on long lines, since AIX grep doesn't.
4768 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4770 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
4771 the output file in the `${datarootdir}' test.
4773 2005-05-28 Stepan Kasal <kasal@ucw.cz>
4774 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4776 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
4777 mention of `datarootdir' in the input file(s), but literal
4778 `${datarootdir}' in the output file, and we haven't warned yet,
4779 then warn as well: the user may have (erroneously) used
4780 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
4781 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
4782 * tests/torture.at (datarootdir workaround): Extend this test.
4785 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4786 and Paul Eggert <eggert@cs.ucla.edu>
4788 * doc/autoconf.texi (autoheader Invocation): The first argument to
4789 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
4790 alternatives and clear up the language a bit.
4792 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
4794 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
4795 ac_config_guess, ac_config_sub, ac_configure.
4796 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4797 Fix typo that prevented an unnecessary space from being removed.
4798 Problems reported by Ralf Wildenhues in:
4799 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
4801 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4803 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
4804 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
4805 Don't use the term "thread-safe" to talk about mkdir race
4806 conditions, since the problem is more a process than a thread
4807 issue. Problem reported by Stepan Kasal in:
4808 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
4809 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
4810 the test for 'install' more closely. Look at MKDIR_P first.
4811 Look in the PATH, and at /opt/sfw/bin.
4812 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
4813 Don't bother to try mkdir -p, since we already check mkdir --version;
4814 just look at the version number. (There's no easy way to check
4815 for race-free implementations.)
4816 * tests/tools.at (autoconf: subdirectories): Adjust to above
4817 changes, since MKDIR_P now might end in "/mkdir -p".
4819 * doc/autoconf.texi (autoheader Invocation): Mention that the
4820 first arg of AC_DEFINE_UNQUOTED must be a literal.
4821 Problem reported by Ben Pfaff in
4822 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
4824 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
4825 * doc/autoconf.texi (Special Chars in Variables): New section.
4826 (Preset Output Variables): Warn about special chars in CPPFLAGS.
4827 (Installation Directory Variables): Quote $(datadir) better.
4828 (Limitations of Builtins): Describe some of eval's trickiness.
4830 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
4831 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
4832 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
4833 in front of every arg, not just trailing args. Quote apostrophes.
4834 (_AC_EVAL_ECHO): New macro.
4835 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
4836 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
4838 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
4839 exposed by quoting of eval argument. Put the command on line line
4841 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
4842 (_AC_PATH_X, AC_PATH_X): Quote more safely.
4843 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
4844 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
4845 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
4846 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
4847 Use eval more safely.
4848 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
4849 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
4851 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
4852 lines, exposed by quoting of eval argument.
4854 2006-05-26 Stepan Kasal <kasal@ucw.cz>
4855 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4857 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
4858 initialization of `ac_cv_exeext', do not override it if it was
4859 already set, unless it was set to `no', for compatibility with
4860 Autoconf-2.13, and comment this.
4861 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
4862 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
4863 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
4864 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
4865 Document that this test may be overridden by setting
4868 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4870 Revert these two patches:
4872 2006-04-06 Eric Blake <ebb9@byu.net>
4873 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4874 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4877 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4878 Clean up _AC_COMPILER_EXEEXT* macros.
4879 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4880 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4881 ac_file to the name of the default output file and call
4882 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4883 initial `rm' of the candidate files...
4884 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4885 the same list in subsequent `rm' calls, and for the temporary
4886 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4887 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4888 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4889 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4890 no longer needed) by libtool. Make it a cache check.
4891 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4892 copied here by mistake.
4893 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4894 _AC_COMPILER_EXEEXT.
4895 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
4896 _AC_COMPILER_OBJEXT directly.
4897 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4899 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4901 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
4902 Fix description of how the buggy `sed' works.
4904 2006-05-25 Noah Misch <noah@cs.caltech.edu>
4908 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
4909 ENOLCK. Only mention `make -j' when applicable. Only raise
4910 fatal errors when `make -j' is involved. Improve error message.
4912 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4914 * doc/autoconf.texi (Here-Documents): We now know more about
4915 the variable expansion in here documents bug.
4916 Thanks to Tim Rice and Stepan Kasal.
4918 * doc/autoconf.texi (Making testsuite Scripts): Add an example
4919 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
4921 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4923 * tests/autotest.at (Multiline command from M4 expansion):
4924 No failure to be expected if the shell quotes newlines in
4925 commands in the `set -x' output. Report by Tim Rice.
4928 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4930 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
4931 expansion in the here-documents used by config.status, as that
4932 runs afoul of the Korn shell version M-12/28/93d bug described in
4933 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
4934 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
4935 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
4937 2006-05-23 Jim Meyering <jim@meyering.net>
4939 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
4940 Fix typo introduced with 2006-04-02 change. It reversed the sense
4943 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4945 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
4946 ac_dB slightly, to save bytes in the script.
4947 Max out at 50 lines, rather than 96; this is more likely
4948 (though not guaranteed) to avoid obscure 'sed' failures.
4950 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4952 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
4953 `tr -d -' as bad option argument. Work around this by deleting
4954 an unrelated character.
4955 Report by Tim Rice <tim@multitalents.net>.
4957 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
4958 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4959 Stepan Kasal <kasal@ucw.cz>
4961 * doc/autoconf.texi (Particular Programs): Do not promise that
4962 we always prefer the GNU version of the program, and that we
4963 search according to PATH; both rules can have exceptions.
4964 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
4965 AC_PROG_SED. Move descriptions of limitations
4966 to the Limitations of Usual Tools section.
4967 (Limitations of Usual Tools) <sed>: Mention script length
4968 limitations with Solaris /usr/ucb/sed.
4969 <grep>: Fix wording for empty alternative. Mention that -c and
4970 -l should not be combined, and that -E and -F should not be
4973 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4974 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4976 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
4977 limits in Solaris 8 /usr/ucb/sed by testing a long script.
4979 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4981 * doc/autoconf.texi (Defining Symbols): Literal parameter of
4982 AC_DEFINE is now passed to m4_pattern_allow.
4983 * NEWS: Mention that; likewise for AC_SUBST.
4984 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
4985 the parameter to m4_pattern_allow.
4986 * tests/tools.at: Add a check for that.
4988 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4990 * lib/autoconf/status.m4: Fix typos.
4992 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4994 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
4995 only the files that this macro generates.
4997 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4999 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5000 the HP-UX sed limitation of 99 commands, labels do not count.
5001 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5003 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5005 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5007 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5008 Import the following fix from coreutils:
5010 2006-01-13 Jim Meyering <jim@meyering.net>
5012 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5013 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5014 not double-quote uses of that variable, to accommodate the rare
5015 case in which getmntent is available in none of the libraries
5016 checked. This happens at least on FreeBSD 5.0.
5018 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5020 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5021 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5022 some other programs unwisely rely on these undocumented vars.
5023 But put in warning comments about them.
5024 Problem reported by Ralf Wildenhues in
5025 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5026 * NEWS: Document that these variables are intended to go away.
5028 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5030 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5031 and set the language to C++ (analogous to the equivalent Fortran
5034 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5035 * doc/autoconf.texi (C++ Compiler): Document it.
5036 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5039 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5041 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5042 that caused config.status to generate 100-command sed scripts; the
5043 portable limit is 99.
5045 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5047 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5048 variable `ac_d' instead of `d' to avoid infringing namespace.
5049 Report by Ralf Menzel.
5051 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5053 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5054 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5055 * tests/tools.at (autoconf: subdirectories): New test, taken from
5056 the corresponding problem report by Ralf Wildenhues in:
5057 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5059 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5060 Quote some uses of shell variables if they might suffer unexpected
5061 globbing. This doesn't fix all instances of quoting problems that
5062 I found, just the easy ones that look safe.
5063 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5064 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5065 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5066 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5067 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5068 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5069 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5071 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5072 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5074 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5076 * bin/autoreconf.in ($help): Reword according to the manual.
5077 Suggested by Olly Betts.
5079 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5080 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5082 * bin/autoreconf.in: Pass the directory argument to
5083 `require_configure_ac'. Fix comment.
5084 * tests/torture.at (Configuring subdirectories): Expose this.
5085 Reported by Olly Betts.
5087 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5089 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5090 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5091 Automake as follows:
5093 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5094 `$configure_in' instead of `configure.in', to preserve
5095 directory component.
5097 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5099 * config/config.guess, config/config.sub, config/texinfo.tex,
5100 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5102 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5104 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5105 test for C99 conformance; (bool) 0.5 is an integer constant
5106 expression, but (bool) -0.5 is not. Problem reported by Fedor
5107 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5109 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5111 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5112 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5113 Warn about obsolete install-sh files. Remove stray sentence
5114 fragment and fix cross reference.
5115 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5116 install -d; this undoes the 2006-05-10 change.
5117 (MKDIR_P): Mark with AN_MAKEVAR.
5118 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5119 that we don't require $INSTALL to be thread-safe. Move comments
5120 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5121 of AC_PROG_INSTALL. Output a message saying that we're checking
5122 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5123 MKDIR_P instead of AC_SUBST.
5124 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5125 Special magic for MKDIR_P, too.
5126 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5128 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5130 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5132 Sync from Automake, as follows:
5134 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5135 * config/install-sh: Initialize IFS, so field splitting isn't
5137 * config/mkinstalldirs: Likewise.
5138 * config/missing: Remove superfluous quotes. Replace all uses of
5139 `[' by `test', for consistency, and for..
5140 * config/missing (sed_minuso, sed_output): New variables.
5141 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5142 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5143 Fixes `missing' to detect `--output' for help2man. Fixes
5144 PR automake/483. Report by Dennis J. Linse.
5145 (autom4te): Document in `missing --help'.
5147 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5149 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5150 * config/install-sh: Don't use 'path' to talk about file names,
5151 as per GNU coding standards. Close a race condition reported by Ralf
5152 Wildenhues and Stepan Kasal. There is still a race condition
5153 on hosts that predate Posix 1003.1-1992, but we can't help this.
5154 Don't mishandle weird characters like space on pre-Posix hosts.
5155 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5156 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5157 AC_PROG_MKDIR_P from AS_MKDIR_P.
5158 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5159 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5160 earlier editions are not (including Automake 1.8.3).
5161 Do not suggest mkinstalldirs for thread-safety.
5162 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5163 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5164 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5165 presence of special characters and race conditions.
5166 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5167 in Autoconf's name space.
5169 2006-05-10 Bruno Haible <bruno@clisp.org>
5170 and Paul Eggert <eggert@cs.ucla.edu>
5172 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5173 from Automake with minor changes.
5174 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5176 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5178 * config/install-sh: Update to Automake CVS version, as follows:
5179 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5180 * lib/install-sh: Simplify the expr implementation of dirname.
5181 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5182 * lib/install-sh: Handle --, and diagnose unknown options.
5184 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5186 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5187 `./autom4te' to create `./testsuite', since the `all' target
5188 will ensure its presence, but `installcheck' should not create
5189 the uninstalled wrappers.
5191 * tests/torture.at (Unusual Automake input files): Skip if we
5192 detect automake < 1.8.
5194 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5196 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5197 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5198 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5201 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5203 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5204 munge (multiple) white space and other oddities.
5205 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5206 single quotes in variable assignment.
5207 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5208 and similar failures by adding multiple spaces, tabs, and other
5210 Report and different test suggested by Francesco Romani
5211 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5213 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5214 single quotes, we only need to search for single quotes; this
5215 both simplifies the search pattern, and makes us less
5216 susceptible to `echo' variations for arguments not containing
5218 (_AC_ARG_VAR_VALIDATE): Likewise.
5220 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5222 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5223 `$*' and IFS concatenation issue with traditional shells and
5224 bash-2.04. Report by Seanster@Seanster.com.
5226 2006-05-03 Bruno Haible <bruno@clisp.org>
5228 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5229 precisely which Mac OS X versions have the od problem.
5231 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5233 * doc/autoconf.texi: Use @option systematically.
5235 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5236 and Bruno Haible <bruno@clisp.org>
5238 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5240 (Integer Overflow): Mention the special case of integer division
5243 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5245 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5246 traditional shells like the Solaris one that do not use the
5247 first IFS character for assembling `$*'.
5248 Prompted by a related report from autoconf_bug@nro.ca.
5250 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5251 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5253 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5254 Mention more problems with the -e option.
5256 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5259 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5261 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5262 in URLs to improve DVI formatted output (requires texinfo 4.6).
5263 (System Services, Systemology, Shellology): Likewise.
5264 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5267 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5269 (Runtime): Fix macro argument names to match description:
5270 `action-if-found' -> `action-if-true' and similarly.
5271 (Obsolete Macros): Likewise.
5272 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5273 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5274 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5276 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5278 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5281 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5284 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5286 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
5287 /bin/sh set unsorted output.
5288 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.

5293 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
5294 (Integer Overflow, Null Pointers, Buffer Overruns):
5295 (Floating Point Portability, Exiting Portably): New sections.
5296 (Writing Test Programs): Fix some langauge. Recommend exiting
5297 with status 1, not merely nonzero. Clarify exit declaration.
5298 (Run Time): Move C exit status stuff to new Exiting Portably section.

5306 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5308 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5309 since as_me isn't set yet.
5311 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5313 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5314 a few minor bugs in this area.
5316 * doc/autoconf.texi (Programming in M4sh): Comment out the
5317 documentation of AS_BASENAME, for now.
5318 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5319 (Limitations of Builtins) <basename>: Do not refer to
5321 * bin/autoconf.as (me): Don't use AS_BASENAME.
5322 (dir): Remove the unused variable.
5323 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5324 AS_DETECT_REQUIRED. All uses changed.
5325 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
5327 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
5328 (AS_BASENAME): Use "basename --" to protect against leading "-".
5329 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
5330 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
5331 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
5332 (_AS_DIRNAME_PREPARE): Likewise.
5333 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
5334 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5335 (AS_DIRNAME): Use "dirname --".
5337 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5339 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5340 of "run time" and "run-time" changed to "runtime", for consistency.
5341 * lib/autoconf/fortran.m4: Likewise (in comment).
5342 * lib/autoconf/functions.m4: Likewise.
5343 * lib/autoconf/general.m4: Likewise.
5344 * lib/autoconf/headers.m4: Likewise.
5346 * doc/autoconf.texi (Run Time): Document the exit status situation
5347 with more accuracy and detail.
5349 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5351 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5352 Archive is not officially `GNU' any more. Update URL.
5353 (Defining Directories): Likewise
5354 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5356 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5358 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5359 newline from the `trap' code to finish `config.log'; the NetBSD
5360 /bin/sh resets the exit status after an empty command, as
5361 documented in doc/autoconf.texi.
5362 Reported by Dalibor Topic <robilad@kaffe.org>.
5364 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5366 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5367 Suggested by Bruno Haible.
5369 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5371 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5372 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5373 Instead, just list the shells that we know work.
5374 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5375 changed. Be more cautious about the _cv_ variable.
5376 * tests/tools.at (Syntax of the shell scripts): Check the
5377 _cv_ variable once, at first, to avoid an internal autoconf error
5378 when sh -n does not work.
5380 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5382 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5384 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5386 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5387 use ">&-" since we're only 99.999% sure that this is portable,
5388 and since the MinGW bug is fixed in a different way.
5389 * lib/autotest/general.m4 (AT_INIT): Likewise.
5391 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5393 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5394 before opening config.log, to avoid hitting a bug on MinGW.
5396 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5398 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5399 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5400 This works around a MinGW bug reported by Eric Paire.
5401 Make sure that all writes to the log file append to it,
5402 rather than possibly losing data.
5403 * lib/autotest/general.m4 (AT_INIT): Likewise.
5405 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5407 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5410 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5414 * configure.ac (AC_INIT): Bump to 2.59d.
5416 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5420 * Makefile.maint (news-date-check): Do not require a leading `*'
5421 before the release date in NEWS.
5423 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5424 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5426 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5427 the instantiated file do not contain the string 'datarootdir'
5428 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5429 @mandir@, replace the reference '${datarootdir}' by the value.
5430 * tests/torture.at (datarootdir workaround): New test.
5431 * NEWS: Advertise this temporary fixup.
5432 Based on a patch by Bruno Haible, reported and analyzed by
5433 Paul Eggert and Noah Misch.
5435 2006-04-12 Eric Blake <ebb9@byu.net>
5437 * tests/autotest.at (Debugging a failed test): Fix comment.
5439 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5441 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5442 all the changes since 2006-04-07.
5444 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5446 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5447 succeeded, but `ln -s file dir' failed, take care to remove the
5448 leftover target before the next test, to prevent its spurious
5449 failure; also make sure `ln file dir' works before selecting it.
5450 Thanks to Keith Marshall for pointing this out.
5453 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5454 assignments in `at_debug_args', so that we put them correctly
5455 in the `run' script.
5456 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5457 Reported by Eric Blake.
5459 2006-04-11 Eric Blake <ebb9@byu.net>
5461 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5462 top-level tests after micro-suite has been run. Used in...
5463 (Debugging a successful test, Debugging script and environment),
5464 (Debugging a failed test): ...these new tests. The first of these
5466 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5467 macro, split out from...
5468 (AT_INIT): ...here, so that using -d also generates a run script.
5469 Document that -d inhibits top-level logging.
5470 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5471 inhibits top-level logging; debug scripts are created.
5473 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5475 * tests/autotest.at (Empty test, Empty check): New test to check it.
5477 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5480 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5482 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5483 the files if a problem appears. Make the empty *.at files
5484 read-only, too. Proposed by Ralf Wildenhues.
5486 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5488 * config/Makefile.am: Add comment to force updated Makefile.in.
5490 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5491 space only patch to this file, this patch causes the Makefile.in
5492 files that include freeze.mk to be updated, and thus have a
5493 newer time stamp again, which in turn makes a pristine CVS
5494 checkout have correct time stamps.
5496 * Makefile.maint (cvs-sv): New macro, to be used..
5497 (config.guess-url_prefix, config.sub-url_prefix)
5498 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5499 point to CVS text checkout of Gnulib files.
5500 (copyright-check): Bump current year.
5501 (announcement): Do not hard-wire `./announce-gen'.
5502 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5504 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5506 (wget_files): Update config.guess, config.sub, texinfo.tex by
5507 `wget-update', now that their URLs work again.
5509 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5511 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5512 Problem noted by Paul D. Smith.
5514 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5516 * doc/autoconf.texi: Remove unused words from word list.
5517 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5518 .x-sc_trailing_space: New files.
5520 * doc/standards.texi: Sync from gnulib.
5522 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5523 `LIBOBJDIR' as experimental.
5525 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5526 with a target directory; it's internally implemented as `cp'
5527 anyway, but since Autoconf advertises the possibility to use
5528 a target directory when LN_S is `ln -s', we need to find out.
5529 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5530 analyzed by Keith Marshall <keith.marshall@total.com>.
5534 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5536 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5537 confdefs.h as-is. In general, if it has backslash-newline or the
5538 like, then it doesn't work either to sort or to remove empty
5541 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5543 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5545 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5547 * lib/autom4te.in (Automake-preselections): Preselect
5550 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5552 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5553 apostrophe within a single-quoted string, as this is the usual
5554 tradition and is easier to read than '"'"'. Don't rely on the
5555 shell treating "$/" like '$/'. Use a more-consistent indenting
5558 2006-04-09 Eric Blake <ebb9@byu.net>
5560 * tests/autotest.at (Backquote command substitution),
5561 (Multiline backquote command substitution): Remove mistaken
5562 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5564 (Parenthetical command substitution, Multiline parenthetical
5565 command substitution): here.
5567 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5569 Import macros from gnulib (often changing their name).

5599 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
5600 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
5601 (C Compiler): Move AC_C_LONG_DOUBLE to ...
5602 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
5603 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
5604 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
5605 (Coding Style). Don't mention m4_expand_once.

5627 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
5629 2006-04-08 Stepan Kasal <kasal@ucw.cz>
5631 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
5632 of the warning introduced by the 2001-08-28 change.
5634 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
5635 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5637 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
5638 variables shall be overriden by the cache.

5642 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5644 Revert the patch from 2006-04-01 and only improve
5645 _AS_DETECT_BETTER_SHELL:
5647 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
5648 skip nonexistent directories.
5649 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
5650 only shell candidates which exist.
5651 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
5652 * lib/autotest/general.m4 (AT_INIT): No need to give three
5653 parameters to _AS_PATH_WALK.
5655 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
5656 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5658 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
5659 distinguish m4sugar macros.
5660 * tests/tools.at (autoupdating with aclocal and m4_include):
5661 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
5662 test case by Noah Misch <noah@cs.caltech.edu>.
5664 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5666 Revert my change from 2006-03-17, in other words:
5667 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
5669 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
5670 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
5673 2006-04-07 Eric Blake <ebb9@byu.net>
5675 * doc/autoconf.texi (Programming in M4sh): Document that
5676 AS_MKDIR_P exits the script on failure.
5677 * lib/autotest/general.m4: Remove redundant AS_ERROR.
5679 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5681 * config/elisp-comp, config/install-sh, config/mdate-sh,
5682 config/missing, config/mkinstalldirs: Sync from Automake.

5697 Paul Eggert <eggert@cs.ucla.edu>,
5698 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5700 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
5701 whether `set' quotes correctly: redirect stderr of the tested
5702 `set', and use a subshell, for Ultrix; use `sed' instead of
5703 `grep' for zsh `set' which may write binary output; match only
5704 at the beginning of a line, to avoid false positives.
5705 In order to avoid false positives by unrelated variables with
5706 multiline content, put the dump algorithm in a subshell and
5707 unset all variables containing newlines (except some which are
5708 special to the shell). Warn about cache variables that are
5711 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5713 * config/config.guess, config/config.sub, config/texinfo.tex:
5716 * tests/mktests.sh: Reword comments.
5718 * tests/mktests.sh: Only skip internal macros starting with

5722 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
5723 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
5724 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
5725 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
5727 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
5728 shell issue with double-quoted command substitutions of native
5730 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
5733 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

5748 2006-04-06 Stepan Kasal <kasal@ucw.cz>
5750 * tests/Makefile.am (maintainer-check-posix):
5751 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
5753 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
5754 ac_config_<foo>s again, sometimes normalized, sometimes not.
5755 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
5756 (AC_CONFIG_COMMANDS): Do not do so here.
5757 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
5758 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
5759 2005-07-25 rewrite. Noticed by Noah Misch.
5761 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define

6709 2005-10-19 Stepan Kasal <kasal@ucw.cz>
6711 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
6713 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>

6716 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
6718 2005-10-04 Stepan Kasal <kasal@ucw.cz>
6720 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
6721 before removing it (chmod -R u+rwx); there are three instances of this.
6723 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6724 Stepan Kasal <kasal@ucw.cz>
6726 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
6727 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
6728 make its content writable before removing it. Remove an errorneous
6729 comment from the end, where the logs of the failed tests are copied
6730 to the main log file.
6732 2005-09-27 Stepan Kasal <kasal@ucw.cz>
6734 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
6735 in case the computer is too quick. Double quote the configure.ac
6738 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
6739 problems if the testsuite were running too fast.
6741 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
6743 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
6744 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
6745 (which belong to Xt, not X itself). See Debian bug 327655.
6746 * NEWS: Mention this.
6748 2005-09-07 Stepan Kasal <kasal@ucw.cz>
6750 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
6752 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
6754 * config/move-if-change: Don't output "$2 is unchanged";
6755 suggested by Ben Elliston. Handle weird characters correctly.
6757 2005-09-06 Stepan Kasal <kasal@ucw.cz>
6759 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
6760 calls, so that the final expansion of this macro is shorter.
6761 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
6762 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
6763 the cleanup there. Use AS_VAR_* macros, to be more general.
6764 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
6766 * lib/autoconf/general.m4: Use AS_IF where appropriate.
6768 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
6770 2005-09-01 Stepan Kasal <kasal@ucw.cz>
6772 * doc/autoconf.texi (Configuration Headers): Add an index entry
6775 2005-08-26 Pavel Roskin <proski@gnu.org>

6778 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
6781 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
6783 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
6784 The previous patch didn't work, so try a better one.
6786 2005-08-26 Stepan Kasal <kasal@ucw.cz>
6788 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
6789 in the example. Reported by Bruno Haible.
6790 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
6791 "if $undefined_var;" succeeds with my shell.
6793 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
6794 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
6795 but change the m4_divert_text to m4_divert_once.
6797 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
6799 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
6800 Work around bug in Solaris /usr/xpg4/bin/awk.
6801 The bug is present in at least Solaris 8 through 10.
6803 2005-08-24 Stepan Kasal <kasal@ucw.cz>
6805 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
6806 some evil values and relying on the fact that $* concatenates the
6807 parameters by the first character from IFS.
6809 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6810 Stepan Kasal <kasal@ucw.cz>
6812 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
6813 first header appears, define AH_HEADER.
6814 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
6815 Update limitations about when to call AC_CONFIG_HEADERS.
6816 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
6817 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
6818 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
6819 ``Configuration Actions''; fix their index entries.
6821 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
6822 options correctly. Process N-M as M-N if M is smaller than N.
6823 Process ranges correctly so that N-N will run only N.
6824 Sort and uniquify the tests that will be run. If there is more
6825 than one test, reinsert the banners for the tests.
6826 * tests/autotest.at (Keywords): Unmark XFAIL.
6828 2005-08-23 Stepan Kasal <kasal@ucw.cz>
6830 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
6831 before passing the macro name to AH_TEMPLATE.
6833 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
6834 now opens log after option processing; in particular, --version
6835 and --help do not touch config.log.
6837 * Makefile.maint: Revert the change from 2005-08-12.
6839 2005-08-22 Stepan Kasal <kasal@ucw.cz>

6843 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
6845 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6847 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
6848 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
6851 * doc/autoconf.texi (Defining Symbols, Changed Results):
6852 Prepend to LIBS, not append, in examples.
6854 2005-08-16 Stepan Kasal <kasal@ucw.cz>
6856 When building in place, set srcdir="."; suggested by Tim Van Holder.
6858 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
6859 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
6860 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
6861 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
6862 does not mean "no --srcdir option".
6864 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6866 * tests/autoscan.at (autoscan): New file.
6867 * tests/suite.at: Use it.
6868 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
6869 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
6871 * tests/autotest.at (Keywords): Test keywords combinations.
6873 2005-08-12 Stepan Kasal <kasal@ucw.cz>
6875 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
6876 add "2>&1"; gzip 1.2.4 prints help on stderr.
6878 2005-07-27 Stepan Kasal <kasal@ucw.cz>
6880 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
6881 was pushdef'ed twice while popped only once. Push it only once.
6882 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
6884 2005-07-26 Stepan Kasal <kasal@ucw.cz>
6886 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
6887 prefixed by mere "===", not "configure: === ".
6889 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
6891 * Makefile.maint: Update from Bison.
6893 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
6894 "<tab>" in comment, so that the point is understandable.
6896 2005-07-25 Stepan Kasal <kasal@ucw.cz>
6898 Rewrite substantial part of lib/autoconf/status.m4.
6899 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
6900 and CONFIG_COMMANDS are not processed in four separate loops.
6901 Instead, there is one main loop. This alows that the common code
6902 is expanded only once, thus config.status (and configure) is smaller.
6904 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
6905 the AC_LIST_FILES and cousins macros are no longer used.
6907 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
6908 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
6909 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
6910 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
6911 contain the initialization, nor the for loop, nor the associated
6912 commands; all these go to ...
6913 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
6914 _AC_OUTPUT_CONFIG_STATUS.
6915 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
6916 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
6917 (_AC_OUTPUT_FILE): The creation of the sed script ...
6918 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
6919 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
6920 _AC_OUTPUT_MAIN_LOOP.
6921 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
6922 _AC_CONFIG_COMMANDS): Use ...
6923 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
6924 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
6925 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
6926 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
6927 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
6928 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
6930 (_AC_CONFIG_UNIQUE): Update.
6931 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
6932 Replaced by this ...
6933 (_AC_LIST_TAGS): ... new common macro.
6934 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
6935 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
6936 (_AC_LIST_TAG_COMMANDS): ... new common macro.
6937 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
6938 this didn't belong to the `config commands' section.
6939 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
6940 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
6941 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
6942 to the `config commands' section either.
6943 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
6944 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
6946 ... and many changes to the comments nearby.
6948 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
6949 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
6950 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6951 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
6952 (#define header templates): The comment at the top of the generated
6953 header now includes the name(s) of the source file(s).
6955 Several unrelated small changes:
6957 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
6958 parameter to AC_DIAGNOSE.
6959 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
6960 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
6961 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
6962 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
6964 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
6965 in AC_OUTPUT doesn't double-quote it either.
6966 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
6969 2005-07-10 Stepan Kasal <kasal@ucw.cz>
6971 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
6972 versions of Portland Group compiler produce single- and double-quoted
6973 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
6974 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
6976 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
6978 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
6979 This is a corrected version of yesterday's patch.
6981 2005-07-07 Stepan Kasal <kasal@ucw.cz>
6983 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
6984 path, too; insert a "===" to emphasize the line.
6986 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
6987 ac_cv_build_alias to ac_build_alias.
6988 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
6990 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
6991 change eliminates it. Problem reported by Alexandre Duret-Lutz.
6992 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
6993 (AC_ARG_VAR): ... here.
6994 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
6997 Keep a list of all precious variables and process them with one simple
6998 for loop, instead of expanding all commands, or, OTOH, complicated
6999 processing of output of "set".
7000 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
7001 variable names in new macro...
7002 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
7003 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
7004 a loop to assign all ac_env_* and ac_cv_env_* variables.
7005 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7007 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7008 its value to shell variable ac_precious_vars and call
7009 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
7010 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
7011 _AC_ARG_VAR_VALIDATE.
7013 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
7014 and the AC_SUBSTs ...

7018 the ac_subst_files section in config.log.

7036 Fix my changes from 2005-07-01; reported by Noah Misch.
7037 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
7038 description, the macro now accepts only a single tag.

7041 Fix cases when the varsions of Autoconf and Autotest don't match.
7042 Reported by Noah Misch.
7043 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
7044 at_top_builddir, for compatibility with older autotest.
7045 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
7046 is not set, use at_top_builddir, for compatibility with older
7047 versions of autoconf.
7049 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7051 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
7052 Problem reported by Patrick Welche.
7054 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
7056 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7057 sed substitution command, so that we allow | in program prefixes
7058 and program suffixes. (& is a problem anyway; we're not fixing
7060 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
7061 configure_input, top_builddir, srcdir, etc.
7062 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7063 PATH_SEPARATOR in AUTOTEST_PATH.
7065 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
7067 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
7068 for loop over config.site files using `set', to allow
7069 directory names containing IFS characters.
7071 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
7073 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
7074 directories with weird names. Apparently some people like living
7075 on the edge. However, improve the test that "pwd" actually does
7076 report a name for the working directory.
7077 * NEWS: Remove the claim that we test for funny chars in dir names.
7079 2005-07-01 Stepan Kasal <kasal@ucw.cz>

7095 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
7096 document to output the default config_* lists to config.status.
7097 Don't recognize option --file, if the functionality is not there.
7098 Likewise for --header; moreover, recognize --he and --h as shortcuts
7099 for --help in that case.
7101 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7102 matches the order of execution. No code changed.

7123 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
7124 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7125 (AC_SUBST): Call it.
7126 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7127 the directory specific variables; but don't call it for configure_input.
7129 2005-06-28 Derek Price <derek@ximbiot.com>
7131 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7134 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7136 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
7137 directory have inherent problems with special characters like spaces,
7138 due to limitations in Make syntax. Problem reported by Alexandre
7140 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
7141 Also, fix Tru64 porting problem with shell patterns,

7153 from Justace Clutter.
7154 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7155 variable into diagnostic. Make the diagnostic an error, not a warning,
7156 because we really don't support spaces and suchlike in dir names.
7157 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7158 Don't worry about backslashes in srcdir; it can't happen now.
7159 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
7160 Simplify ac_optarg handling.

7185 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
7186 b, t, r, w commands require single space, while : cannot have any.
7187 (Special Shell Variables): Fix sed code this in the example.
7188 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7189 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
7191 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

7197 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
7199 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
7201 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
7202 * doc/autoconf.texi:
7203 Don't mention Solaris versions so much, if a
7204 problem is common to all extant versions of Solaris. Say "SunOS
7205 4" instead of "SunOS" for SunOS 4.
7206 (awk): Mention more of the limitations of traditional Awk.

7217 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
7218 on Mac OS X 10.4 reported by Peter O'Gorman in:

7249 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7250 -u, since it outputs chatter if the input files are the same.
7251 Problem reported by Ralf Menzel.
7253 2005-06-08 Derek Price <derek@ximbiot.com>
7255 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7256 renaming them since they are about to be redefined anyhow.
7258 2005-06-08 Derek Price <derek@ximbiot.com>
7260 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7261 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7262 Move m4_undefine to alphabetical order.
7264 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
7266 * README: Recommend GNU M4 1.4.3 or later.
7267 * doc/autoconf.texi (Introduction): Likewise.
7268 Reword to avoid some formatting glitches.
7269 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7270 Clarify explanation of HP compiler bug.
7271 Redo example output tp match current CVS snapshot.
7272 Use @example.org in email addresses when the examples
7273 might get inadvertently cut-and-pasted into user code.
7274 Remove example of autom4te usage that doesn't seem to work now.
7275 Use modern AC_INIT (except when the example is meant to be
7276 shown with Autoconf 2.13).
7277 Update ksh info for Solaris 9 and later.
7279 Modernize description of Automake versions a bit.
7280 Don't claim a future version of Autoconf is near.

7286 follows its own advice about quoting better.
7287 Reword to avoid some formatting glitches.
7288 * doc/installt.exi: Reword to avoid some formatting glitches.
7290 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7291 Tru64 ksh pattern matching bug. Reported against Libtool by
7292 Albert Chin <libtool@mlists.thewrittenword.com> and
7293 Nicolas Joly <njoly@pasteur.fr>.
7295 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7297 m4_cdr of one-member list was [[]] (one-member list containing an
7298 empty string) instead of [] (an empty list. Callers were skewed to
7299 match this misbehaviour. As a consequence of this:
7300 - m4_foreach([x], [], [foo]) expanded to `foo', while
7301 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7302 This bug has been fixed:
7304 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7305 expand to an empty string; print error msg if called without
7307 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7308 misbehaviour; handle [] and [[]] correctly.
7310 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7312 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

7314 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
7316 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7318 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7319 swallow records with more than 99 fields.
7320 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7321 parse the long line.
7323 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7325 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7326 swallow literals longer than 399. Reported by Ralf Wildenhues.
7327 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
7328 to workaround this limitation.
7330 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
7332 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7333 to gfortran, and make these the first two compiler names
7334 checked (following the general autoconf preference for gcc).

7338 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7339 (DISTCLEANFILES): Remove $(check_SCRIPTS).

7344 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7345 expression of unbounded size when processing the --list
7346 option. This runs afoul of a limit of 399 bytes per regular
7347 expression on AIX. Problem reported by Ralf Wildenhues.
7349 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

7352 * doc/autoconf.texi (Particular Headers): Reword example
7353 for multiline stdbool replacement.

7355 give all the details about |#_!!_#|.
7356 Reword description of line replacement.
7358 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7360 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7361 now contain newlines, and substituted files must be referenced on
7362 a line alone; the sed scripts to substitute them are now very
7364 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
7365 commands can be put in a sed script portably.
7366 * doc/autoconf.texi (Setting Output Variables): Document above
7367 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
7368 use of multiline substitution.

7379 classes in shell scripts. The test was too brittle.
7381 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7383 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
7384 * doc/autoconf.texi (Limitations of Builtins): Document this
7387 2005-05-24 Stepan Kasal <kasal@ucw.cz>
7389 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
7390 common code; used in many places in the tree.
7391 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
7392 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
7394 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
7396 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
7397 messages when ac_unique_file is not found.
7398 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7399 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
7400 commands, for consistency with AC_MSG_ERROR and such.
7402 * bin/autoconf.as: Make more use of "shift 2" in option processing.

7412 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7414 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
7415 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7416 (ac_top_builddir): ... this ...
7417 (ac_top_build_prefix): ... to this; the old name is also kept, for
7418 backward compatibility.
7419 (ac_top_builddir_sub): New variable, without the trailing slash,
7421 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
7422 * doc/autoconf.texi (Configuration Actions): Rename

7435 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7436 argument to m4_foreach. I guess it was necessary in the past,
7437 but I think it's a no-op now.

7441 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7442 ``cat <<_ACEOF'' commands to one.

7448 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7450 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for

7522 Also, throughout this document, be more careful about white space.
7523 "blank", "white space", and "space" all have different meanings

7575 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7576 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7577 comment and reduce m4_default([foo], []) to [foo].
7578 (m4_strip): Update the explanation.
7580 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7582 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7583 Remove core.conftest.* too; it's generated by Tru64 5.1.
7584 Problem reported by Jennis Pruett.
7585 * lib/autoconf/functions.m4
7586 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7587 Don't bother to remove core files; AC_RUN_IFELSE should do that

7592 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

7632 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7634 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
7635 Merge `-z option' as well for the benefit of Solaris link flags. Pass
7636 whole-archive (-zallextract, -zdefaultextract) options in the hope of
7637 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
7638 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.

7642 * NEWS: The configure command now warns you if you attempt to use
7643 a directory whose name contains a special character like space,

7658 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
7659 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
7660 ac_pwd, and quote srcdir.
7661 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
7663 * doc/autoconf.texi: Fix some systematic formatting problems.
7664 ".)" needs a following @: if not at the end of a sentence, and
7665 similarly for "!)". "etc." should be preceded by a comma.
7666 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
7668 2005-03-22 Bruno Haible <bruno@clisp.org>
7670 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
7671 argument is often called 'build-aux'.
7673 2005-03-07 Stepan Kasal <kasal@ucw.cz>

7682 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
7683 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
7684 from a Common Lisp's `cl'.
7685 (AC_PROG_CXX): Behave according to the documentation: don't
7686 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
7687 make the variable CCC precious; use `cl.exe', not `cl'.
7689 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7690 Alexandre Duret-Lutz <adl@gnu.org>
7692 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
7693 /dev/null, as "configure" shouldn't read stdin, and this insulates
7694 us from problems (e.g., when testing for "cl"). Also, do this
7695 redirection before invoking "hostname" or "uname", and keep the
7696 original input stream available via...
7697 (AS_ORIGINAL_STDIN_FD): ... this new macro.
7698 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

7710 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
7711 newline if neither \c nor -n work, as that would output two
7712 newlines. Prefer -n to \c. Reported by Stepan Kasal.
7714 2005-02-12 Stepan Kasal <kasal@ucw.cz>
7716 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
7717 This causes that any required macros inside will get before the if.

7720 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
7722 Undo previous change, except keep the change to
7723 lib/autoconf/programs.m4 that replaced grep with shell
7724 pattern-matching. This is because net-snmp configure reads stdin.
7725 Reported by Noah Misch.
7727 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
7729 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
7730 from /dev/null, as "configure" shouldn't read stdin, and this
7731 insulates us from problems (e.g., when testing for "cl").
7732 Suggested by Alexandre Duret-Lutz. Also, do this redirection
7733 before invoking "hostname" or "uname".
7734 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7735 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
7736 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
7737 "</dev/null" since it's now done at the top of 'configure'.
7738 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7739 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7740 Also, replace grep with shell pattern-matching, to save a process.

7744 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,

7763 Fix some @code's that should have been @env's, and vice versa.
7764 Sort environment variable names.
7765 Mention that shells no longer inherit IFS.
7766 Don't recommend PATH_SEPARATOR=';' so strongly.
7767 Mention that $RANDOM might expand to the empty string.
7768 "symlink" and "soft link" -> "symbolic link".

7845 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

7848 2047-byte limit on line length of portable text files.

7908 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
7909 Update the long comment explaining it.
7911 m4_require no longer writes an ``is required by'' line to the
7912 execution stack. It contains only one bit of non-redundant
7913 information: that the macro was required, not called. And even
7914 this bit is useless in most situations: have you ever met a macro
7915 which both calls and requires the same macro?
7917 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
7918 (_m4_defun_pro_outer): ... only via this macro, for the outermost

7921 (m4_expansion_stack_pop): Remove the misplaced comment.

7923 execution stack; slightly improve the out-of-a-defun error message.
7924 (_m4_divert_grow): New macro, counter for the temporary diversions.
7925 (_m4_require_call): Use it.
7926 * tests/m4sugar.at (m4_require): Expect output without the
7927 ``is required by'' messages.
7929 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

7965 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
7966 Warn about newline stripping in `` and $(). Update Solaris
7968 (Limitations of Builtins): Use expr "X...", not expr "x...", as
7969 X insulates us from future changes to Posix.
7970 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
7973 2005-01-19 Stepan Kasal <kasal@ucw.cz>

7997 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

8018 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
8019 (_m4_divert_n_stack): New macro; the expansion is
8020 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
8022 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
8023 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8024 stored in _m4_divert_diversion or _m4_divert_dump.
8025 (m4_divert_pop): When the parameter is given, compare the symbolic
8026 name with the last diversion pushed on the stack. Previously, the
8027 current diversion was compared with the numeric value of the
8028 diversion given as the parameter.
8029 (m4_require): If the macro hasn't been expanded yet, call ...
8030 (_m4_require_call): this new macro.

8063 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
8064 signals that the package uses Automake; a `Makefile.am' is typical but
8065 not essential. Reported by Magnus Therning.

8550 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
8552 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
8553 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
8554 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
8556 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
8558 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
8559 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
8560 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
8561 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
8562 * lib/autom4te.in (Automake-preselections): Preselect
8563 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8565 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8567 * lib/autom4te.in (Automake-preselections): Preselect
8568 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
8571 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
8573 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
8575 * doc/autoconf.texi (Shellology): Mention BIN_SH.
8576 Document problem with "`""`" in pdksh POSIX mode.
8578 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
8580 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
8581 with pdksh, too. Problem reported by Patrick Welche via
8583 * doc/autoconf.texi (Shellology): Note that set -o posix is
8584 useful for pkdsh, too.
8586 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
8588 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8589 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8590 Don't fail if ENV or BASH_ENV is readonly.
8591 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
8592 etc. are read only. Problem reported by Ludovic Courtes.
8594 2004-06-23 Noah Misch <noah@cs.caltech.edu>
8596 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
8597 zsh, disable GLOB_SUBST to avoid backslash handling problems.
8600 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
8602 * doc/autoconf.texi (File System Conventions): Warn about
8603 names like "aux". Problem reported by Eric Blake.
8605 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
8606 by zero instead of array size, so that we can use any arithmetic
8607 constant expression (instead of requiring an integer constant
8608 expression). This allows us to test expressions like DBL_MAX <
8609 LDBL_MAX, which didn't conform to the C standard using the old
8611 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
8612 now that we can do floating-point tests at compile time.
8614 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8616 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8617 and LDBL_EPSILON, as the resulting expression isn't an
8618 integer constant expression and violates the C standard.
8619 Problem reported by Nelson H. F. Beebe. Also, check
8620 for "L" suffix, and check that long double doesn't have
8621 worse range or precision than double, that mixed-mode
8622 arithmetic doesn't generate a diagnostic, that double
8623 constants fit in long double.
8625 2004-06-03 Kevin Ryde <user42@zip.com.au>
8627 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
8628 malloc(0) and realloc(NULL,size).
8630 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
8633 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
8635 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
8636 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
8639 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8641 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
8642 can be rewritten using if-then-else. Suggested by Bruno Haible.
8644 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
8646 * doc/autoconf.texi (testsuite Scripts): Fix typo.
8647 Problem reported by Stepan Kasal.
8649 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8651 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
8652 change). Patch reported by Ralf Wildenhues in
8653 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
8655 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8656 function F exists if the compiler and linker let you compile an
8657 expression like (F != 0). Recent versions of GCC optimize away
8658 the reference to F in that case, since every function address must
8659 be nonzero, so the link succeeds even if F does not exist.
8660 Problem reported by Manu in
8661 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
8663 * doc/autoconf.texi (Systemology): Standardize on the spelling of
8664 "Unix". Many uses changed.
8665 (Limitations of Builtins): Explain better why the ! command isn't
8668 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
8670 * lib/autom4te.in (Automake-preselections): Preselect
8671 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
8673 2004-05-19 Kevin Ryde <user42@zip.com.au>
8675 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
8676 referencing AC_FUNC_STRERROR_R.
8678 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
8679 note pessimistic assumption when cross compiling.
8681 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
8683 * doc/autoconf.texi (Limitations of Make): Note that BSD make
8684 (until 2004) invoked subcommands with sh -e, contra POSIX.
8685 Reported by Kevin Ryde.
8687 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
8689 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
8690 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
8691 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
8692 `test -f " /usr/bin/grep"', which _always_ failed.
8693 (AC_PROG_SED): Ditto bogus PATH fix.
8694 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
8695 requires that grep correctly supports _multiple_ `-e' options, rather
8696 than stating only that grep should accept `-e'.
8698 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
8700 Port to C99, which requires that 'exit' be declared.
8702 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
8703 to ensure that stdlib.h is included.
8704 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
8705 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
8706 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
8707 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
8708 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
8709 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
8710 when using 'exit' in a test; C99 requires that 'exit' be declared.
8712 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
8714 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
8715 now prefers 'grep' implementations that accept -e.
8716 (Limitations of Usual Tools): Describe problems of traditional
8717 egrep and fgrep with long input lines, and of traditional grep
8719 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
8720 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
8721 All callers changed. Append /usr/xpg4/bin to the PATH, for
8723 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
8724 the user with complaints about multiple -e options.
8725 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
8726 Define it with AC_PROG_GREP.
8727 * configure.ac (AC_PROG_GREP): Add.
8728 * lib/freeze.mk (GREP): New macro.
8730 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
8732 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
8733 a possible candidate only after all others fail, rather than
8734 consulting it first. This improves backward compatibility by
8735 better reflecting the way shell selection occurred in previous
8736 versions of Autoconf, and should help to avoid triggering latent
8737 problems in other packages, such as the one in Automake where zsh
8738 is not handled robustly:
8739 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
8740 Although it is not Autoconf's responsibility to work around
8741 problems in Automake, it nevertheless makes sense to avoid
8742 introducing unnecessary incompatibilites.
8744 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
8745 Gary V. Vaughan <gary@gnu.org>
8747 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
8748 how deeply nested we are when a suitable tool is found, set the
8749 ac_path_TOOL_found flag.
8750 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
8751 nested we are in this macro. Break out of all 3 nested loops if
8752 ac_path_TOOL_found is set.
8754 2004-04-21 Gary V. Vaughan <gary@gnu.org>
8756 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
8757 of the _AS_PATH_WALK loop too if GNU flavor is found.
8759 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
8761 * doc/autoconf.texi (Limitations of Make): Update documentation
8762 for `$<'. New entry `Long lines', based on a report from Simon
8763 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
8764 paragraph about DJGPP, based on a mail from Richard Dawe.
8766 2004-04-20 Paul Eggert <eggert@twinsun.com>
8768 * tests/c.at (C keywords): Don't assume that GCC supports
8769 "restrict" and "inline", as sufficiently-old GCC versions do not
8770 (also, GCC configured to be in pedantic C89 mode does not).
8771 Problem reported by Sumit Pandya in:
8772 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
8774 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
8775 consider -g to work if it generates warnings when plain compiles
8776 don't. Problem reported by Braden McDaniel in:
8777 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
8779 * doc/autoconf.texi (Slashes): New section, to document a problem
8780 reported by Jim Meyering in:
8781 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
8783 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
8784 linker output files before linking, to work around IRIX 6 linker bug.
8785 Problem reported by Rainer Orth in:
8786 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
8788 2004-04-20 Gary V. Vaughan <gary@gnu.org>
8790 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
8791 best tool so far counter rely on the tool path variable name to
8792 avoid checks for one tool being affected by the results of running
8793 the length check on a previous tool.
8795 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
8796 match expression argument, as different greps have different
8797 regular expression flavours.
8798 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
8800 (AC_PROG_EGREP): Pass 'EGREP$'.
8801 (AC_PROG_GREP): Pass 'GREP$'.
8803 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
8805 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
8806 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
8808 2004-03-29 Paul Eggert <eggert@twinsun.com>
8810 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
8811 Types, Specific Compiler Characteristics, System Services,
8812 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
8813 etc. consistently instead of 'long', 'short', 'unsigned' etc.
8814 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
8815 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
8817 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

8826 2004-03-28 Paul Eggert <eggert@twinsun.com>
8828 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
8829 now defines HAVE_DECL_TZNAME if it is declared, when
8830 HAVE_STRUCT_TM_TM_ZONE is not defined.
8831 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
8832 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

8841 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
8843 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
8844 Fortran compiler is ifort, also added pghpf; thanks to Nelson
8845 H. F. Beebe for the bug report.
8847 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
8849 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
8850 quoted -cmdline argument in Portland Group compiler (bug
8851 reported by Jeffrey J. Barteet).

8899 2004-03-03 Paul Eggert <eggert@twinsun.com>
8901 * bin/Makefile.am (edit): Don't use $< in a context where
8902 POSIX doesn't require support for it. Use $@.in instead.
8903 Problem reported by Anthony N. Frasso in
8904 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

8933 AC_SUBST provides no portable way to escape literal newlines.
8935 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
8936 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
8937 Darwin uses -lcrt2.o and there's little point to cataloging all
8938 the system variants. Partial fix reported by Andreas Waechter in:

9014 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9015 2003 (except 1997) to the list of copyright years. This undoes
9016 the 2003-05-22 change, which removed the older years from the list.
9017 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

9028 egrep and fgrep respectively if $GREP -E/-F don't work.
9029 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
9030 _AC_PROG_GREP, and AC_PROG_SED.
9031 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the

9063 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9064 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9065 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9066 not <inttypes.h>. Problem reported by Tim Mooney in
9067 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9068 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9071 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9072 otherwise "make check" fails because it forbids cmp (I guess
9073 because cmp treats files as binary on DOS-like systems).

9088 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9089 -std1 disables some useful extensions on Tru64. Problem reported

9093 2004-01-14 Paul Eggert <eggert@twinsun.com>
9095 * doc/autoconf.texi (Programming in M4sh): Document that
9096 AS_MKDIR_P succeeds if the destination is a symbolic link
9097 to an existing directory.
9098 (Limitations of Usual Tools): Note that mkdir -p might not
9099 succeed on symlinks to directories.
9101 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9103 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

9117 2004-01-09 Paul Eggert <eggert@twinsun.com>
9119 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9120 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9121 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9122 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9123 AC_COMPILE_IFELSE, since we now assume our caller invokes
9124 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9125 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9126 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9127 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9129 2004-01-07 Paul Eggert <eggert@twinsun.com>
9131 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9132 `"'...'"`, as it's confusing (and I suspect it may not work on
9133 some platforms). The code was incorrect anyway, as it assumed
9134 that \$ evaluated to itself in that context. Reported by
9135 Alexandre Duret-Lutz.
9137 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9139 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

9172 * Makefile.am (autom4te-update):
9173 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

9189 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9190 -c -o might not work. From a suggestion by Kevin Ryde.
9191 (C Compiler, Generating Sources, Limitations
9192 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9193 Don't put '-o' after non-options, as POSIX doesn't allow this.
9194 Mention that cc's name might be gcc or c89 or whatever.
9196 2004-01-04 Kevin Ryde <user42@zip.com.au>

9205 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9207 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9208 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
9209 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
9210 explanation clearer.

9221 * tests/atlocal.in: Store the result here.
9222 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

9489 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
9490 Issue a more-informative diagnostic.
9491 Problems reported by Eric Sunshine.
9493 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
9495 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
9496 -mGLOB_options_string stuff for Intel ifc, which can cause
9497 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
9498 pattern-matching instead of grep.
9500 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
9502 * doc/autoconf.texi: Document new FC Fortran macros.
9504 2003-10-08 Gary V. Vaughan <gary@gnu.org>
9506 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
9507 that future autopoint/aclocal/automake/autoreconf will be able
9508 to trace to find where to install local m4 macros.
9509 * doc/autoconf.texi (Input): Document it.
9512 2003-10-06 Gary V. Vaughan <gary@gnu.org>
9514 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
9515 -lcrtbegin.o to list of ignored flags and fix underquoting of
9518 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
9520 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
9521 cache variable instead of $G77 to decide whether to include -O2,
9522 since $G77 is specific to Fortran 77.
9524 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9526 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
9527 free" flag. Re-order flags tested into rough order of popularity.
9529 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9531 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
9532 arguments so that it can be used with syntax identical to
9533 AC_PROG_F77, and so that we can more easily decide to
9534 remove/deprecate the DIALECT optional argument in the future if it
9536 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
9537 non-freeform-supporting compilers. Document freeform flags.
9539 2003-10-03 Akim Demaille <akim@epita.fr>
9541 * configure.ac: Look for emacs, not macs.
9542 Reported by Eric Sunshine.
9544 2003-10-03 Akim Demaille <akim@epita.fr>
9546 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
9547 * bin/autoreconf.in (autoreconf_current_directory): Create the
9548 AUX_DIR if needed, for sake of automake --add-missing etc.
9549 Suggested by Alexandre Duret-Lutz.
9551 2003-10-03 Akim Demaille <akim@epita.fr>
9553 * configure.ac: Quotation and formatting changes.
9554 (EMACS): Don't set it if it is not recent enough to support

9587 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
9588 have been created when invoking the compiler.

9599 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
9600 Problem reported by Lars J. Aas in
9601 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
9602 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
9603 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
9604 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
9606 2003-09-26 Akim Demaille <akim@epita.fr>
9608 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
9609 directory for AC_CONFIG_COMMANDS' first argument exists.
9610 This makes valid the invocation of _AC_SRCPATH that follows.
9611 Reported by Eric Sunshine.
9612 * doc/autoconf.texi (Configuration Commands): Adjust.
9614 2003-09-26 Akim Demaille <akim@epita.fr>
9616 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
9617 Reported by Ralf Corsepius.
9619 2003-09-26 Akim Demaille <akim@epita.fr>
9621 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
9623 Actually, use AU_ALIAS.
9626 2003-09-26 Paul Eggert <eggert@twinsun.com>
9628 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
9629 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
9630 Problem reported by Eric Sunshine in:

9635 The test suite are sometimes assigning timings incorrectly.
9636 Reported by Henk Krus.
9637 Diagnosed by Nicolas Joly.
9639 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
9641 Instead of making AT_help a sequence of assignments to grow
9642 $at_help_all, just make AT_help_all be the growing contents of
9643 $at_help_all, and make a single assignment in...
9645 (at_times_skip): Flip the meaning and rename as...
9647 (AT_INIT): When summarizing the test that ran, remove
9648 $at_times_file after use, and check it is present before trying to
9651 2003-09-25 Akim Demaille <akim@epita.fr>
9655 * bin/Makefile.am (edit): Handle '@configure_input@'.
9656 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
9657 (ifnames): chmod -w.
9658 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
9659 executables, not bin/ executables! Otherwise all the magic needed
9660 to find non installed files is turned off. This caused a failure
9661 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
9662 as found in its environment (sent by tests/autoreconf): pointing
9663 to bin/autom4te that could not find its files.
9664 * tests/mktests.sh: Force the replacement of generated files, for
9665 the sake of "mv" program that are interactive when overwriting a
9667 * config/install-sh: Upgrade from CVS Automake.
9669 2003-09-23 Paul Eggert <eggert@twinsun.com>
9671 * doc/autoconf.texi (Limitations of Builtins): Document test -h
9672 versus test -L issues.
9674 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
9675 Paul Eggert <eggert@twinsun.com>
9677 Trivial change to support GCC's configuration procedure.
9678 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.

9713 willing to edit the output files.
9715 2003-09-10 Akim Demaille <akim@epita.fr>
9717 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT

9743 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
9745 2003-09-04 Akim Demaille <akim@epita.fr>

9756 2003-09-04 Akim Demaille <akim@epita.fr>
9758 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
9760 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
9762 Add support for newer Fortran dialects. The F77 interface is
9763 unchanged, and continues to support Fortran 77. New FC macros
9764 correspond to all the old F77 macros, with output variables FC,
9765 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
9766 available dialect, but older dialects can be specified. There are
9767 new macros AC_FC_SRCEXT to set the source extension, and
9768 AC_FC_FREEFORM to accept free-form source files.
9770 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

9803 * tests/m4sugar.at (cross_warning): Make sure to enable the
9804 output, so that we can track spurious m4sugar output.
9805 * tests/local.at: Require 2.57.
9806 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
9807 are defaulted by AT_CHECK anyway.
9808 Use AT_CHECK_AUTOM4TE.
9809 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a

9884 Use &verb, not &verbose.
9886 2003-08-21 Akim Demaille <akim@epita.fr>
9888 * bin/autoheader.in (&parse_args): Use &parse_warnings and
9890 ($help): Use Autom4te::ChannelDefs::usage.
9891 * bin/autoscan.in: Use Autom4te::ChannelDefs.
9892 * lib/Autom4te/General.pm: Don't export error: you don't own it.
9894 2003-08-21 Akim Demaille <akim@epita.fr>
9896 First stab at preserving warnings between calls to autom4te,
9897 including when the cache is used.
9899 There are still several issues: (i) there are too many runs of m4
9900 (one for include, one for warnings, and some more), (ii) warnings
9901 spreading on several lines are not handled gracefully, (iii) the
9902 code meant to have the call stack display for errors does not work
9903 (its handling should move from m4 to autom4te).
9905 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
9907 (@preselect): Add m4_warn.
9908 ($exit_status): Remove, use $exit_code.
9909 ($help): Use Autom4te::ChannelDefs::usage.
9910 (&handle_m4): No longer define the m4_warnings.
9911 At each run, extract and report the warnings.
9912 Always cache the result, including if the exit status is on
9913 failure, since if nothing changes, we should result in the same
9914 failure, hence we can use the cache.
9915 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
9916 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
9918 (m4_warn): Redefine as a do-nothing: it is its invocation that
9919 matters, as warnings are now reported via traces.
9920 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
9921 the contents of m4_warn: make it _call_ m4_warn, so that tracing
9922 the latter reveals calls to the former.
9926 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
9928 2003-08-21 Akim Demaille <akim@epita.fr>
9930 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

9955 Reported by Alexandre Duret-Lutz.

9959 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
9960 * bin/autom4te: Adjust.
9961 In particular, be Autoconf tools are really silent when properly
9962 working, bind the verbosity of the 'note' channel to $verbose.
9963 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
9964 (&xsystem, &contents): Remove, since they are exported by...

10036 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
10037 (AT_CHECK_NOESCAPE): Move core functionality to...
10038 (_AT_CHECK): ...this new macro.
10040 2003-08-07 Derek Price <derek@ximbiot.com>
10042 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
10043 (AT_CHECK_NOESCAPE): ...to this new macro.
10045 2003-07-31 Paul Eggert <eggert@twinsun.com>
10047 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
10048 in Bash 2.01. Problem reported by Brian Gough in
10049 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

10053 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
10054 -lcrt1.o, for OS X. (trivial change)
10056 2003-07-07 Paul Eggert <eggert@twinsun.com>
10058 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
10059 inside '#ifndef __cplusplus'. Problem reported by
10062 2003-07-06 Bill Clarke <llib@computer.org>
10064 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10065 'long', not 'int', for benefit of Sun's recent C++ compilers
10066 (trivial change). See:
10067 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

10073 * lib/Makefile.am (autom4te.cfg): Make it read only.
10074 Depend on Makefile since it contains substitutions.
10075 From Paolo Bonzini.
10076 * lib/autom4te.in (args): Add local.at? for Autotest args.
10077 This change was made on autom4te.cfg which is generated.

10080 2003-06-25 Akim Demaille <akim@epita.fr>
10082 * doc/autoconf.texi (Header Portability): sys/mount.h.
10083 From Gareth McCaughan.
10085 2003-06-23 Akim Demaille <akim@epita.fr>
10087 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10088 not all of them. This fixes 1. the fact that when testing
10089 Autoconf there are many many config.log, 2. the incorrect use of
10090 top_srcdir to find config.log.
10091 Don't mix the detailed output of failed test with the summary of
10092 failures. Rather, append detailed log afterwards.
10094 2003-06-23 Akim Demaille <akim@epita.fr>
10096 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
10097 always run: output config.log on $at_group_log.
10099 2003-06-23 Akim Demaille <akim@epita.fr>
10101 * tests/torture.at (#define header templates): Don't use quotes in
10102 C++ comments as it puzzles Emacs' sh font-lock-mode.
10104 2003-06-23 Akim Demaille <akim@epita.fr>
10106 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
10107 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
10108 * tests/atspecific.m4: Rename as...
10109 * tests/local.at: This.

10115 2003-06-21 Kevin Ryde <user42@zip.com.au>
10117 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
10118 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
10119 ensuring we add -std1 for full-ANSI.
10121 * doc/autoconf.texi (hdrindex): New macro.
10122 Add index entries for portability of various standard header files.
10124 2003-06-20 Akim Demaille <akim@epita.fr>

10132 2003-06-20 Akim Demaille <akim@epita.fr>

10151 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
10152 (TEST_SCRIPT): New diversion.

10154 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
10155 (AT_INIT): Support for expected failures.
10157 2003-06-02 Akim Demaille <akim@epita.fr>
10159 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space

10162 Autoconf nor Automake.
10163 (&contents): New, from Automake.
10166 2003-05-28 Paul Eggert <eggert@twinsun.com>
10168 * NEWS, doc/autoconf.texi (Particular Functions),

10170 is the inverse of localtime.
10172 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
10174 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10175 (handle_exec_errors): New function. Work around $! being
10176 altered by WEXITSTATUS.
10177 (xqx, xsystem): Use handle_exec_errors.
10179 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10181 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10182 Do not call `_exit()', simply modify `$?'.
10183 (xsystem): Reset $! before running system, and check it afterward.
10184 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10185 63 for version mismatches.
10187 2003-05-23 Akim Demaille <akim@epita.fr>
10189 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10190 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10191 the middle of a line).
10192 * lib/m4sugar/m4sugar.m4: Likewise.
10193 Remove useless spaces in comments.
10195 2003-05-23 Akim Demaille <akim@epita.fr>
10197 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10198 exit 63, so that we (or Automake's "missing") can tell the
10199 difference with a plain failure.
10200 * doc/autoconf.texi (Notices): Adjust.
10202 2003-05-23 Akim Demaille <akim@epita.fr>
10204 * Makefile.am, bin/Makefile.am, config/Makefile.am,
10205 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
10206 White spaces cleanup.
10208 2003-05-22 Jim Meyering <jim@meyering.net>
10209 Paul Eggert <eggert@twinsun.com>
10211 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10212 Remove `#include <stdlib.h>' from the list; we should never
10213 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10214 resulting namespace pollution would cause other tests to fail.
10215 Configure scripts run with some older versions of g++ and HP's
10216 aCC would fail due to such an #include. Problems reported by
10217 Matthew Mueller in <http://bugs.debian.org/120704> and by
10219 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10220 In the test, use the test declaration before including <stdlib.h>,
10221 as that's closer to how it'll be used.
10223 2003-05-23 Akim Demaille <akim@epita.fr>
10225 * doc/autoconf.texi (Header Portability): ucred.h.
10228 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10230 Overhaul Autotest's logging: generate separate log files
10231 in testsuite.dir/NNN/testsuite.log, and append them to
10232 testsuite.log instead of re-running the test verbosely.
10234 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10235 file descriptor, write 0 to at_status_file instead of setting
10236 at_status=0, initialize some new variables (at_status_file,
10237 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10238 to rerun the tests, instead append the at_group_log to the
10239 at_suite_log when a test fails.
10240 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10241 with the AS_MESSAGE_LOG_FD redirected to stdout.
10242 (AT_CLEANUP): save the output status in $at_status_file
10243 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10244 its original place.
10245 (AT_CHECK): since tests are run with a redirected stdout,
10246 and used to be re-run in verbose mode, turn some $at_verbose
10247 into echo, and don't redirect the output of testing stdout
10250 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10251 the name of the debugging directory and information about

10368 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
10371 2003-05-06 Akim Demaille <akim@epita.fr>
10373 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10374 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10375 by aclocal.m4 is changed it might require the importing of another
10376 m4 extension file, i.e., aclocal must be run.
10378 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10379 (&parse_args): Use --force with aclocal if required and supported.
10380 (&autoreconf_current_directory): Use &run_aclocal.

10393 2003-04-29 Derek Price <derek@ximbiot.com>
10395 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10396 seperator with m4_append_uniq(). It doesn't work.
10397 (AT_CLEANUP): Add `;' to end of at_help_all.
10398 (AT_INIT): Allow --keywords to be specified more than once. When
10399 grepping $at_help_all for keywords, use the field and keyword
10400 seperators to ensure a complete keyword match. Alter at_prev handling
10401 to support the new --keywords behavior.
10403 2003-04-27 Karl Berry <karl@freefriends.org>
10405 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10406 align better with others. I also made some of the individual
10407 entries on one line, for brevity and to make it easier for me to
10408 sort my dir-example file in the Texinfo distribution :).

10468 documentation to read is Autoconf's.
10469 Suggested by Paul Eggert.
10471 2003-03-28 Akim Demaille <akim@epita.fr>
10473 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
10474 reading the section "Present But Cannot Be Compiled" when the
10475 header causes problems.
10477 2003-03-28 Akim Demaille <akim@epita.fr>
10479 * tests/torture.at (Configuring subdirectories): Require aclocal

10503 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
10504 obsolete AC_HELP_STRING.
10505 (AC_HELP_STRING): AU_DEFUN to...

10569 * bin/ifnames.in: Add final newline to help and version messages.
10571 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
10572 to cope with DOS-style absolute paths, when constructing
10575 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
10576 When constructing paths with IFS=:, quote the path. If we're
10577 constructing a DOS-style absolute path, we don't want to split it
10580 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
10583 2003-02-25 Pavel Roskin <proski@gnu.org>

10600 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
10601 format starting with "-".
10603 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
10605 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
10606 is not portable inside Makefile.
10608 2003-02-20 Akim Demaille <akim@epita.fr>
10610 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
10611 compiler says yeah, but preproc says nope, compiler is right.
10612 Conversely, prompt the reader to send a bug report to the
10613 maintainers of the package, not of Autoconf.
10615 2003-02-20 Klee Dienes <kdienes@apple.com>
10617 * bin/autoreconf.in (autoreconf_current_directory): Properly

10623 $ac_prefix_program.
10626 2002-12-23 Paul Eggert <eggert@twinsun.com>
10628 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10629 innocuous variant befor including <limits.h> or <assert.h>. This
10630 works around a bug reported by Albert Chin: HP-UX 11i
10631 (and earlier versions) have a <limits.h> that declares
10632 gettimeofday and many other functions.
10634 2002-12-03 Paul Eggert <eggert@twinsun.com>
10638 * NEWS, configure.ac: Update version.
10640 * doc/fdl.texi: Upgrade to FDL version 1.2.
10642 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
10643 nontrivially in main's body, so that f's external declaration is
10644 not optimized away in AIX. This should fix the bug reported by
10646 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
10648 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10649 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10650 defined, to support freestanding compilers. This should fix the
10651 bug reported by Momchil Velkov in
10652 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10654 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10655 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

10686 Update from masters.
10688 2002-11-14 Akim Demaille <akim@epita.fr>
10690 * Makefile.maint: Sync with Bison, i.e.:
10691 (po-check): Scan .l and .y files instead of the
10692 .c and the .h files that they generate. This fixes the bug
10693 reported by Tim Van Holder in:
10694 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
10695 Look for N_ as well as for _. Try to avoid matching #define for
10699 2002-11-14 Akim Demaille <akim@epita.fr>
10701 * doc/autoconf.texi (C Compiler): Compiling several files at once.
10702 From Paul Eggert and Albert Chin-A-Young.
10704 2002-11-14 Akim Demaille <akim@epita.fr>
10706 * doc/autoconf.texi (C Compiler): Solitary backslashes.
10707 From Paul Eggert and Albert Chin-A-Young.

10711 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
10712 than assigning in main, to avoid HP cc +O3 optimizing it away.
10714 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
10716 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
10717 option. Process --recheck after parsing all options. Pass -q
10718 option to configure on --recheck.
10719 (AC_OUTPUT): Pass -q from configure to config.status.
10720 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
10721 arguments to record.
10722 * doc/autoconf.texi (config.status Invocation): Document
10723 config.status -q option.
10725 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
10727 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
10728 Makefile.in if Makefile.am exists.
10729 (output): Strip `.am' from Makefiles. Don't
10730 output AC_CONFIG_FILES if no Makefiles were found.

10750 Reported by Ezra Peisach.
10752 2002-11-05 Akim Demaille <akim@epita.fr>
10754 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
10756 We _have_ to stop using the old compatibility scheme that tried to
10757 avoid useless backslashes because Libtool 1.4.3 contains a
10758 AC_DEFINE([error_t], [int],
10759 [Define to a type to use for \`error_t' if it is not
10760 otherwise available.])
10761 We _have_ to quote the single quote and backslashes with \. The
10762 old compatibility scheme saw that ` was backslashed, and therefore
10763 did not quote the single quote. Hence before this patch, Autoconf
10764 was not compatible with Libtool.
10766 2002-11-04 Paul Eggert <eggert@twinsun.com>
10768 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

10786 ($help, $make, &parse_args, &autoreconf_current_directory):
10788 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10790 2002-10-31 Bruno Haible <bruno@clisp.org>

10808 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
10809 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
10810 Make variable, not a shell variable.
10811 Suggested by Bruno Haible.
10813 2002-10-31 Akim Demaille <akim@epita.fr>
10815 * bin/autom4te.in (load_configuration): Reject #args out of any
10818 2002-10-31 Akim Demaille <akim@epita.fr>
10820 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.

10834 2002-10-29 Paul Eggert <eggert@twinsun.com>

10837 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
10838 Problem reported by Bruno Haible.
10840 2002-10-29 Akim Demaille <akim@epita.fr>
10842 * doc/autoconf.texi (Header Templates): Put also in words what the
10843 pictures says to assist free style readers.
10844 (Customizing autom4te): s/--cache=/--cache /.
10846 2002-10-29 Akim Demaille <akim@epita.fr>
10848 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
10850 sparc_address_test returns void.
10851 Use it with an argument, as prototyped.
10854 2002-10-29 Akim Demaille <akim@epita.fr>

11155 Reported by Alexandre Duret-Lutz.
11157 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

11177 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11178 if some file was changed instead of `print'.
11179 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

11214 From Sam Varshavchik.
11216 2002-10-08 Akim Demaille <akim@epita.fr>
11218 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11219 aclocal invocation, as Gettext macros might not be visible to
11221 Instead of blindly running autopoint, scan configure.ac (not the
11222 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11223 Reported by Paul D. Smith.
11225 2002-10-08 Paul Eggert <eggert@twinsun.com>
11227 Work around problems found when POSIXLY_CORRECT=1 is set.
11228 None of this seems to have anything to do with POSIX, really,
11229 but it's how Perl getopt works.
11230 * bin/autom4te.in (parse_args): Configure GetOpt with
11232 * doc/autoconf.texi (Invoking autom4te):
11233 --warning -> --warnings.

11255 * tests/torture.at (Configuring subdirectories): Be robust to
11256 users who use config.site to require for a cache: in this case,
11257 the two last configure runs, using two different sets of
11258 arguments, trigger a legitimate error.

11424 2002-09-13 Akim Demaille <akim@epita.fr>

11479 2002-09-09 Akim Demaille <akim@epita.fr>
11481 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
11482 looking for a replacement file.
11483 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11484 directory is relative.
11485 * doc/autoconf.texi (Generic Functions): Clarify the replacement
11486 directory definition.
11487 Reported by Andreas Schwab and Jim Meyering.

11491 * doc/autoconf.texi (Setting Output Variables): Clarify what
11492 precious variables are.
11493 Suggested by Pontus Skoeld.
11495 2002-09-05 Akim Demaille <akim@epita.fr>
11497 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11498 (ifnames, autoscan, autom4te): Since we don't only depend on
11499 configure.ac variables (such as VERSION etc.), but also on prefix
11500 and so forth, depend on Makefile, not configure.ac.
11501 Reported by Alexandre Duret-Lutz.
11502 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11504 2002-09-05 Kevin Ryde <user42@zip.com.au>
11506 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11507 doesn't seem to be confined to ia64, just say "some versions".
11509 2002-09-04 Akim Demaille <akim@epita.fr>
11511 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11513 * Makefile.am (maintainer-clean-local): Remove.

11516 2002-09-03 Paul Eggert <eggert@twinsun.com>
11518 * doc/autoconf.texi (Configuration Commands): Remove obsolete
11519 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
11522 2002-09-03 Akim Demaille <akim@epita.fr>
11524 * configure.ac: Bump to 2.53d.
11525 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11526 as of today, on Automake's team suggestion.
11528 2002-09-03 Akim Demaille <akim@epita.fr>
11532 2002-09-02 Akim Demaille <akim@epita.fr>
11534 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
11536 * configure.ac: Disable SITE_MACRO_DIR.
11538 2002-09-02 Jim Meyering <meyering@lucent.com>
11540 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11541 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11542 Also, tweak grammar: s/make sure to/be sure to/.
11544 2002-09-02 Paul Eggert <eggert@twinsun.com>
11546 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11547 directory names are generally preferable to physical names.
11549 2002-09-02 Akim Demaille <akim@epita.fr>
11551 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11552 Reported by Raja R. Harinath.
11553 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11554 * bin/autoupdate.in: Use error instead of die.
11556 2002-09-01 Paul Eggert <eggert@twinsun.com>
11558 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11559 ordinary shell concatenation rather than echo+tr+sed command that
11560 runs afoul of a long-line-related sed bug in Solaris 8.
11562 * bin/autoheader.in (parse_args): --warning -> --warnings.
11564 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11565 stdout, as traditional "ls" does.
11566 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11567 _AC_COMPILER_EXEEXT_O): Likewise.
11568 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11570 * bin/autoconf.as: Add --prepend-include option. This patch was
11571 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11572 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11574 * bin/autoconf.in, configure: Regenerate.
11576 * doc/autoconf.texi (Special Shell Variables): Mention
11577 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11579 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11580 MAILPATH and set PS1, PS2, PS4 to default values, to work
11581 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11582 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11583 the Autoconf documentation specifies; fall back to "unset" only if
11584 this fails. Use a shell for-loop for this rather than an m4 loop,
11585 to shorten the output script.
11587 2002-08-30 Paul Eggert <eggert@twinsun.com>
11589 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11590 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11591 for the CDPATH problem. Document PWD.
11592 (Limitations of Builtins): Document the problem that "cd $foo" and
11593 "ls $foo" may refer to different directories in shells conforming
11594 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11595 example, since the old example is now out of date.
11597 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11598 FOO" and "ls FOO" talk about different directories; this catches
11599 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11602 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11603 of rolling our own unset.
11604 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
11605 in practice we needn't worry about CDPATH if unset doesn't work.
11607 * Makefile.in, aclocal.m4, bin/Makefile.in,
11608 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
11609 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
11610 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
11611 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
11612 tests/Makefile.in: Regenerate with Automake 1.6.3.
11614 * config/config.guess, config/config.sub, config/mkinstalldirs:
11617 * configure: Regenerate with self.
11619 2002-08-30 Kevin Ryde <user42@zip.com.au>

11629 2002-08-29 Akim Demaille <akim@epita.fr>
11631 * lib/Autom4te/General.pm (&xqx): New.
11632 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11633 hand, which is not portable.
11635 * bin/autom4te.in: Use them.
11636 Use &error instead of die.
11637 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11640 2002-08-17 Paul Eggert <eggert@twinsun.com>
11642 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
11643 default list of compilers to try, since it was long ago superseded
11644 by the ksh fc builtin. Suggested by Steven G. Johnson.
11646 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
11648 * doc/autoconf.texi (Invoking autom4te): End the option table,
11649 fixing a bug introduced by the previous patch.
11650 (Limitations of Make): Add a 'target lookup' subentry in the
11651 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
11653 2002-07-29 Mark D. Roth <roth@feep.net>
11655 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
11656 options and use $AUTOM4TE_PATH.
11657 * doc/autoconf.texi: Remove documentation of autom4te
11658 --include-envvar and --site-macro-subdir options and document
11659 use of $AUTOM4TE_PATH.
11660 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
11661 arguments from each language section.
11663 2002-07-29 Paul Eggert <eggert@twinsun.com>
11665 * doc/install.texi: Include copyright symbol in copyright notice.
11667 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
11669 (AM_MAKEINFOFLAGS): New macro.
11670 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
11671 * Makefile.am (INSTALL): Use the new macros.
11672 Use -o rather than --output, since "missing" does not grok --output.
11674 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11676 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
11677 comments do not always work. Never trust the exit status of
11680 2002-07-24 Kevin Ryde <user42@zip.com.au>
11682 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
11683 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
11685 2002-07-23 Paul Eggert <eggert@twinsun.com>
11687 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
11688 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
11689 apparently treats PATH="nonexistent" as if it contained ".".
11690 Bug reported by Stefan `Sec' Zehl.
11692 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11694 * doc/autoconf.texi (Limitations of Make): Mention the special

11954 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
11956 2002-05-17 Paul Eggert <eggert@twinsun.com>
11958 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
11959 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
11960 This improves on an earlier suggestion by H. Peter Anvin.
11962 2002-05-16 Paul Eggert <eggert@twinsun.com>
11964 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
11965 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
11966 Both macros now accept an optional source-dir arg.
11967 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
11969 * NEWS: Document this.
11970 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
11972 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
11973 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
11974 not for GNU extensions; this undoes part of the 2000-11-03 change,
11975 reverting to 2.13-compatible behavior.
11976 Add new optional argument DIR.
11977 (AC_FUNC_FNMATCH_GNU): New macro.
11979 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
11981 2002-05-08 Paul Eggert <eggert@twinsun.com>
11983 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
11984 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
11985 and it causes a 'test' syntax error if it fails.
11986 Bug reported by Stephen Gildea.
11988 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
11989 If prototypes are supported, use them to check this at compile-time,
11990 instead of trying to check it at run-time. If we must do a run-time
11991 check, assume that setvbuf is standard when cross-compiling, as
11992 nonstandard setvbuf occurs only on ancient and unlikely hosts.
11993 Bug reported by Paul D. Smith.
11995 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
11996 argument specifying location of getloadavg.c. This removes a
11997 FIXME. This idea was taken from Jim Meyering's implementation in
11999 * doc/autoconf.texi (Particular Functions): Document this.
12000 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12001 that's what the code does; this fixes a bug reported by
12004 2002-05-03 Akim Demaille <akim@epita.fr>
12006 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12007 autopoint instead of gettextize.
12008 ($uses_alocal): Rename as...
12009 ($uses_aclocal): this.
12010 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12011 Suggested by Bruno Haible.
12013 2002-05-03 Akim Demaille <akim@epita.fr>
12015 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12017 2002-04-29 Paul Eggert <eggert@twinsun.com>
12019 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12020 files to be 1 second older; just set them to be the same time.
12021 Also, sleep 1 second after the first aclocal, to work around
12022 problems with sub-second time stamps on the input files.
12024 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12026 * doc/autoconf.texi: Mention "set -e -x" lossage
12027 under node "Limitations of Builtins".
12029 2002-04-29 Akim Demaille <akim@epita.fr>
12031 * doc/install.texi: Better wording for setting variables when
12033 From Christian Cornelssen.
12035 2002-04-29 Akim Demaille <akim@epita.fr>
12037 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12038 of lack of $LINENO support, then the test will compare the $LINENO
12039 in testsuite vs. the lineno in the test file. This is wrong, of
12041 Be sure to protect it.
12042 Reported by Patrick Welche.
12044 2002-04-25 Akim Demaille <akim@epita.fr>
12046 * doc/autoconf.texi (Obsolete Macros): Typo.
12047 Reported by Vladimir Volovich.
12049 2002-04-25 Akim Demaille <akim@epita.fr>
12051 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12052 than some of the input files, hence, on the second run of aclocal,
12053 if some of its input are younger, make them older.
12054 Suggested by Paul Eggert.
12056 2002-04-25 Akim Demaille <akim@epita.fr>
12058 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
12059 Thanks to Paul Eggert.
12061 2002-04-25 Akim Demaille <akim@epita.fr>
12063 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12064 and ac_subst_vars be sh variables containing the list of
12065 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12067 (_AC_INIT_PREPARE): Use them to log them.
12068 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12069 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12070 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12071 _AC_SUBST_FILES and _AC_SUBST_VARS.
12072 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12074 2002-04-24 Akim Demaille <akim@epita.fr>
12076 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12077 autoheader, so that automake does not complain about a missing
12078 config.h.in that was to be created.
12080 2002-04-23 Akim Demaille <akim@epita.fr>
12082 * bin/autoheader.in (parse_args): --warning takes an argument.
12085 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
12087 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

12132 Minor spelling and grammar fixes.
12134 * doc/autoconf.texi: Follow the outline suggested in the GNU
12135 Sample Texts sections of the Texinfo 4.2 manual. Most
12136 importantly, this makes sure that the copyright notices appear in
12137 all output formats. You probably need Texinfo 4.2 to generate

12178 From Oliver Kiddle and Peter Stephenson.
12180 Have M4sh perform minimal shell sanitizing.
12182 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12184 (_AS_PREPARE): this new macro.
12186 (AS_INIT): Invoke AS_SHELL_SANITIZE.

12189 Adjust Autoconf and Autotest.

12200 * tests/wrapsh.as: New, precursor of wrapsh.in.

12202 on Autotest and M4sh.

12223 2002-04-05 Akim Demaille <akim@epita.fr>
12225 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
12226 directories when descending in a SUBDIRS.

12238 Use dnl, not the KILL diversion.
12240 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12241 (AC_CONFIG_LINKS): here.
12243 Don't use the KILL diversion, as it kills spurious output, which
12244 results in failures being hidden.
12245 Use m4_defn where appropriate.
12246 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12247 after the second argument.
12249 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12250 syntax, as it is provided by M4sugar.

12295 2002-03-27 Paul Eggert <eggert@twinsun.com>
12297 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

12315 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12317 * doc/autoconf.texi (Limitations of Make): Mention more issue
12318 about VPATH, overriding of macros in sub-makes, and handling of
12321 2002-03-21 Paul Eggert <eggert@twinsun.com>
12323 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12324 problem with here-document buffer boundaries.
12326 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12327 when reinvoking the shell, to work around problems with installers
12328 who put strange things like "cd" commands in their environments.

12353 (Limitations of Usual Tools): Add mkdir section.
12355 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12356 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12357 back on AS_DIRNAME to compute prefixes otherwise; this is
12358 roughly what mkinstalldirs does. That way, we need not have
12359 our own filename disassembler. The old disassembler did not
12360 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12362 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12363 Create at_test_all by a series of assignments,
12364 not by a single assignment of a long string. The latter causes ksh
12365 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12366 presumably because of a buffer overrun.
12368 2002-03-14 Paul Eggert <eggert@twinsun.com>
12370 * lib/autotest/general.m4 (at_times_skip):
12371 Renamed from at_times. Now a boolean.
12372 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12373 says 'times: not found'.

12428 * bin/autom4te.in (&handle_m4): Protect us from corrupted file

12456 2002-03-04 Akim Demaille <akim@epita.fr>
12458 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
12461 2002-03-04 Akim Demaille <akim@epita.fr>
12463 * doc/autoconf.texi (Transforming Names): Equality between target
12464 and host is irrelevant.
12465 (Specifying Names, Canonicalizing): Remove all references to the
12466 backward compatibility hooks. Rather, collect them all into...
12467 (Hosts and Cross-Compilation): this new section.
12468 * doc/install.texi (System Type): Ditto.
12469 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12470 that `--host' implies cross-compilation.
12472 2002-03-04 Akim Demaille <akim@epita.fr>
12474 * doc/autoconf.texi (Evaluation Macros): New.
12475 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12477 (_m4_foreach): Define the variant with immediate evaluation so
12478 that it contains exactly the items, not an expression which
12479 evaluation is the current item.
12480 (m4_re_string, m4_re_word): Don't over quote them.
12482 2002-03-04 Akim Demaille <akim@epita.fr>
12484 Instead of having stacking `shift's evaluated at the end, let
12485 `foreach' loops immediately evaluate them.
12487 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12488 $*. This is the n-th time I change my mind, but hopefully this is
12491 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12493 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12494 it was only a hack for m4_text_wrap.
12495 (m4_car2): Remove, replaced by...
12497 (_m4_foreach): Adjust.
12498 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12499 m4_bpatsubst for clarification.

12551 AC_PREFIX_PROGRAM fails with dashed program names
12553 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
12554 variable when looking for the prefix program.

12572 sure not to introduce newlines in at_groups.

12586 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
12587 cross-compilers, too. This undoes some of the most recent change
12590 2002-02-05 Akim Demaille <akim@epita.fr>
12592 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
12593 to make sure they are up to date when `check' is run.
12595 2002-02-05 Akim Demaille <akim@epita.fr>
12597 * doc/autoconf.texi (Making testsuite Scripts): Document
12600 2002-02-05 Akim Demaille <akim@epita.fr>

12609 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
12610 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
12612 2002-02-05 Akim Demaille <akim@epita.fr>
12614 * bin/autom4te.in (&parse_args): Implement `frozen files are
12615 optional are the sum of the previous files on the command line'.
12616 Also, pass `--reload-state=' on them, so...
12617 (handle_m4): don't.
12618 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
12619 (M4sh): Rely on M4sugar.
12620 (Autotest, M4sh, M4sugar): Use frozen files.

12657 2002-01-28 Akim Demaille <akim@epita.fr>
12659 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12660 AUTOTEST_PATH *after* it was set.
12661 Don't put `.' in the PATH: the user should be precise and `./' if
12662 needed. In addition, given that the test suite does some `cd', if
12663 `.' is in the path, the `tested programs' sections will report
12664 programs found in the test suite's directory, while during the
12665 tests (performed in their own directory), these programs are no
12666 longer visible. In other words, the results is confusing and
12668 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

12712 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
12713 message on invalid options.
12714 * bin/autom4te.in (parse_args): Don't use
12715 Autoconf::General::getopt with non valid options.
12717 2002-01-17 Jim Meyering <meyering@lucent.com>
12719 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
12720 $ac_cv_exeext so we don't use an old, invalid, cached value.

12734 package.m4, since is really depends upon configure.ac, not
12736 * doc/autoconf.texi (testsuite Scripts): Adjust.
12737 * tests/Makefile.am (package.m4): New.
12738 EXTRA_DIST it since its a source.
12740 2002-01-06 Akim Demaille <akim@epita.fr>
12742 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
12743 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
12744 and PACKAGE_BUGREPORT from here...
12745 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
12747 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
12748 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
12749 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
12750 * tests/tools.at (autoheader): Adjust.

12770 * doc/autoconf.texi (New Macros): Tweak wording.
12772 2001-12-14 Akim Demaille <akim@epita.fr>
12774 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
12775 trailing files, don't apply `-rf' to files which might not be
12776 created by configure (core, core.*, and *.core), but just `rm -f'.
12777 Suggested by Jonathan Kamens.
12779 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
12781 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

12803 2001-12-12 Kevin Ryde <user42@zip.com.au>

12806 forbidden file descriptors table.
12808 2001-11-26 Akim Demaille <akim@epita.fr>
12810 * bin/autoscan.in (%c_keywords): Build it at top level.
12811 Map to 1 in order to simplify its uses.
12813 2001-11-26 Akim Demaille <akim@epita.fr>
12815 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
12816 Remove $filepath, useless.
12817 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
12818 variables, they are really part of the tokens.
12819 Split the input line on spaces and then look for tokens.
12820 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
12821 because of `lex$U.$(OBJEXT)'.
12822 (&scan_files): Use "@list" instead of join.

12828 Remove, replaced by...
12829 * tests/wrappl.in: Be common for all the Perl executables.
12830 In particular autoscan and autoheader want -I.
12831 * configure.ac: Adjust.
12832 * lib/autoscan/headers: errno.h is portable.
12834 2001-11-26 Akim Demaille <akim@epita.fr>

12861 Test groups are now run two directories deeper.
12863 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,

12866 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
12867 top_srcdir, builddir and top_builddir.
12868 Use `at_*dir' relatively to the directory containing the
12869 suite, use `*dir' when relatively to the current group dir.

12878 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12880 * doc/autoconf.texi (Using System Type): Add an example of `case
12881 $host' usage so people quit using `case $target' everywhere.
12883 2001-11-22 Akim Demaille <akim@epita.fr>
12885 * doc/autoconf.texi (Installation Directory Variables): Englishoes
12886 spotted by Jim Meyering.
12888 2001-11-16 Paul Eggert <eggert@twinsun.com>
12890 This patch implements a `long double' suggestion by Oliver Kiddle.
12892 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
12893 static, to catch errors if the value isn't known at compile-time
12894 and the compiler supports dynamic arrays. Change its name from
12895 `_array_' to `test_array' to avoid potential name clashes.
12896 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
12897 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
12898 better than double. Catch a bug in GCC 2.95.2 x86.
12899 * doc/autoconf.texi (C Compiler): Document the above.
12902 2001-11-13 Akim Demaille <akim@epita.fr>
12904 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by

12908 2001-11-13 Akim Demaille <akim@epita.fr>
12910 * lib/autotest/general.m4 (AT_INIT): After having run the test
12911 group, go back to the initial directory, not to at_suite_dir.
12913 2001-11-13 Akim Demaille <akim@epita.fr>
12915 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
12916 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
12917 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
12919 (AT_CHECK_CONFIGURE): Use absolute paths.
12920 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
12921 The problem is still the old one: there is no means in M4 (that I
12922 know about) to create a defining macro, because there is no means
12923 to create `$1' etc., therefore, the defining macro ``swallows''
12924 all the arguments meant to the defined macro.
12926 2001-11-13 Akim Demaille <akim@epita.fr>
12928 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.

12935 * lib/autotest/general.m4: Change `tests?' into `groups?' in
12936 variable names when referring to a single test group, or to
12937 `suite' when referring to the whole test suite.
12938 `at_last_test' is removed: m4 compute at_format itself.
12939 (at_stdout, at_stder1, at_stderr): New variables.
12940 (AT_CHECK): Use them.
12942 2001-11-13 Akim Demaille <akim@epita.fr>
12944 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
12946 Create `testsuite.dir/003/run' instead of `testsuite.003'.
12947 Do it as soon as a test fails, don't wait till the end of the test
12949 Don't remove $as_me.[0-9]*, since these files no longer exist.
12951 2001-11-13 Akim Demaille <akim@epita.fr>
12953 * tests/tools.at: Use absolute paths, since we are no longer run
12956 2001-11-13 Akim Demaille <akim@epita.fr>
12958 Now that tests are running in their own private dir, there is no
12959 need to list the files to remove at the end of tests groups.
12961 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
12962 (AT_data_files, at_data_files): Remove.
12963 (AT_CLEANUP, AT_DATA): Simplify.
12965 Remove the group dir if !debug && !failed.
12966 * tests/atspecific.m4: Adjust.
12968 2001-11-13 Akim Demaille <akim@epita.fr>
12970 Start a new layout for Autotest: `testsuite' creates
12971 `testsuite.dir' in which the at-check-line etc. files are to be
12972 found, and `testsuite.dir/003' where the test group 3 is run.
12974 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
12975 at_check_line_file, at_format, at_test_normalized, at_group_dir
12977 Create the directories.
12978 Use absolute paths for at- files.
12979 (AT_CHECK): Adjust.
12981 2001-11-11 Michael Matz <matz@kde.org>
12983 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
12985 (m4_car): Properly quote arguments.
12987 2001-11-13 Akim Demaille <akim@epita.fr>
12989 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
12990 with stricter rules on LIBOBJS.
12992 2001-11-12 Paul Eggert <eggert@twinsun.com>
12994 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
12995 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
12998 2001-11-12 Akim Demaille <akim@epita.fr>
13000 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13002 2001-11-12 Akim Demaille <akim@epita.fr>

13007 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13008 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13009 specify to what the macro should be defined (typically to 1).
13011 2001-11-12 Akim Demaille <akim@epita.fr>
13013 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13016 2001-11-12 Akim Demaille <akim@epita.fr>
13018 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13019 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13020 definition used by Automake where LEX is +/- "${missing} lex" and
13021 `missing' itself contains variables.
13023 2001-11-12 Akim Demaille <akim@epita.fr>
13025 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13026 Now that M4sh pushes BODY, the comments were output at the end of
13029 2001-11-08 Akim Demaille <akim@epita.fr>
13031 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13032 that we can trace macros from aclocal.m4.
13033 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13034 obsoleted, and redirect to the former anyway.
13035 Reported by Ralf Corsepius.
13037 2001-11-08 Akim Demaille <akim@epita.fr>
13039 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13040 processed only if present.
13041 * tests/torture.at (Configuring subdirectories): Use autoreconf
13042 instead of successive calls to autoconf.
13043 Add a nonexistent subdirectory to exercise the patch above.
13044 Reported by Ralf Corsepius.
13046 2001-11-08 Kevin Ryde <user42@zip.com.au>
13048 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13049 doesn't accept .S files.

13055 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13056 * bin/autom4te.in (warn_forbidden): New.
13057 (handle_output): Use it.
13058 Read m4_pattern_forbid with messages.
13060 2001-11-05 Akim Demaille <akim@epita.fr>
13062 * bin/autom4te.in (--normalize): Remove.
13063 * lib/autom4te.in: Adjust.
13065 2001-11-05 Akim Demaille <akim@epita.fr>
13067 * tests/Makefile.am (testsuite): Rename this target as...
13068 ($(TESTSUITE)): this.
13071 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13073 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13074 the --prefix option, also remove it's argument.
13076 2001-11-05 Akim Demaille <akim@epita.fr>
13078 * doc/autoconf.texi (testsuite Invocation): Update.
13079 (Writing testsuite.at): Update.
13081 2001-11-03 Akim Demaille <akim@epita.fr>
13083 * doc/autoconf.texi: s/@code/@command/ where appropriate.
13085 2001-11-03 Akim Demaille <akim@epita.fr>
13087 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13088 (&file_name_is_absolute): New, wrappers around routines from
13090 Use and export them.
13091 (&find_configure_ac): Optionally take a directory where to look at.
13092 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13094 Default @ARGV to `.', not find_configure_ac.
13095 (&autoreconf): Argument is a directory.
13096 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13097 * doc/autoconf.texi (autoreconf Invocation): Update.
13099 2001-11-03 Akim Demaille <akim@epita.fr>
13101 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13102 (@export_forward_subs): New.
13103 Add basename, dirname, and fileparse.
13105 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13106 Don't look for aclocal flags if we already know aclocal is not
13108 Move aclocal.m4t only if it exists.
13109 Reported by Ezra Peisach.
13111 2001-11-03 Akim Demaille <akim@epita.fr>
13113 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13114 passed on command line, defaulting to ./configure.ac if present.
13115 (&maybe_autoreconf, File::Find): Remove, unused.
13116 (&autoreconf): If autoconf is not used, don't try to trace.
13118 2001-11-02 Akim Demaille <akim@epita.fr>
13120 * configure.ac: Bump to 2.52g.
13122 2001-11-02 Akim Demaille <akim@epita.fr>
13126 2001-11-02 Akim Demaille <akim@epita.fr>
13128 * config/config.guess, config/config.sub, doc/standards.texi:
13129 * config/lispdir.m4: Update from masters.
13130 * configure.ac: Bump to 2.52f.
13132 2001-11-02 Akim Demaille <akim@epita.fr>
13134 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13135 Don't run aclocal when aclocal.m4 is not from aclocal.
13137 Don't run libtoolize and gettextize if --install is not given.
13139 2001-11-01 Paul Eggert <eggert@twinsun.com>
13141 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13142 be invoked before _AS_LINENO_PREPARE.
13143 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13144 than character ranges.
13146 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13147 invoking AS_BASENAME. Set the locale variables to 'C' if
13148 possible, as POSIX requires this to get the traditional
13150 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13152 2001-10-31 Paul Eggert <eggert@twinsun.com>
13154 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13155 with {}, as that triggers a bug in Bash 2.05.
13157 (_AS_LINENO_PREPARE): Use Sed rather than
13158 Awk. Fix the sed prepass to work even if there are multiple
13159 instances of $LINENO on the same line. Do not substitute for
13160 other variables like $LINENOT. Do not check file dates; such a
13161 check is unreliable on sufficiently fast machines, and removing
13162 the check makes the code simpler and more reliable. Check for
13163 output and chmod failures.
13165 * doc/autoconf.texi (Special Shell Variables): Document
13168 2001-10-31 Akim Demaille <akim@epita.fr>
13170 * tests/Makefile.am (atconfig): Remove this target, Automake
13173 2001-10-31 Akim Demaille <akim@epita.fr>
13175 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13176 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13177 provided, while it is optional.
13178 * configure.ac: Adjust.
13180 2001-10-26 Paul Eggert <eggert@twinsun.com>
13182 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13183 lib/Autom4te/Struct.pm:
13184 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13187 * doc/autoconf.texi (Special Shell Variables): Document some
13188 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13190 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13191 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13192 eval $LINENO is not portable in practice.
13194 2001-10-24 Akim Demaille <akim@epita.fr>
13196 * lib/Autom4te/General.pm (backname): New.
13198 2001-10-24 Akim Demaille <akim@epita.fr>
13200 * m4/: Remove, merged into...
13203 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
13205 * doc/autoconf.texi (Shellology): Mention the problems with bash
13206 2.05's use of ANSI quoting in its `set' builtin.
13208 2001-10-22 Paul Eggert <eggert@twinsun.com>
13210 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13211 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13212 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13213 POSIX decided to standardize on the int flavor of strerror_r.
13214 Always do char* test, as there's no reason not to.
13215 Assign to a char* var, to catch strerror_r that returns int*.
13217 * doc/autoconf.texi (Particular Functions):
13218 Document the above changes. Also, document the fact that
13219 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13221 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13223 2001-10-20 Akim Demaille <akim@epita.fr>
13225 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
13226 the executable was missing from the log.
13228 2001-10-20 Akim Demaille <akim@epita.fr>
13230 * lib/Autom4te/General.pm (&update_file): If destination is
13231 unchanged, remove the source.
13232 (&up_to_date_p): Don't be verbose, be debug.
13233 * bin/autoreconf.in: No longer support --m4dir.
13234 (&autoreconf): Display the full path of the configure.ac we are
13236 Trace it only once.
13237 Be sure to honor --force with gettextize.
13238 Always run aclocal.
13239 * doc/autoconf.texi: Adjust.
13241 2001-10-20 Akim Demaille <akim@epita.fr>
13243 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13245 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13246 `intl' is already present, as it refuses unless --force.
13247 (&parse_args): Use -I, --include instead of the old Autoconf
13249 ($localdir, $autoconf_dir): Remove.
13251 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13253 2001-10-19 Jens Petersen <petersen@redhat.com>
13255 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

13271 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
13273 * bin/autoreconf.in (autoreconf): Display the path to the
13274 configure.ac being studied.
13276 2001-10-18 Paul Eggert <eggert@twinsun.com>
13278 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13279 long, to work around a bug in the HP C compiler version HP92453-01
13282 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13283 (AS_BASENAME_EXPR): New macro.
13284 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13285 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13286 and fall back on 'sed' only if the other two fail. This makes
13287 AS_BASENAME act more like AS_DIRNAME.
13288 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13289 contains white space.
13290 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13291 Use AS_DIRNAME, since I think it's now DOS-friendly.
13292 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
13293 Allow "dirname //FOO" to return either / or //, as POSIX allows
13296 2001-10-10 Akim Demaille <akim@epita.fr>
13298 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

13304 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
13305 m4_define, since...

13342 (Syntax of the shell scripts): Don't.

13433 shell does not support LINENO, and if CONFIG_SHELL is unset or
13434 empty, and if we can find a shell that does support LINENO,
13435 then set CONFIG_SHELL to that shell and then re-execute
13436 ourselves with CONFIG_SHELL.

13440 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
13441 doesn't exist. Remove *.tmp, as a .tmp file is created during the

13483 compatibility with POSIX shells.

13512 Don't use nested parenthesization. This patch was originally
13513 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
13514 but somehow it didn't get incorporated then.

13522 Check for `expr' arithmetic overflow, and for compilation failure,
13523 and invoke a new argument $4 if either is discovered.
13524 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13525 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
13527 2001-09-28 Akim Demaille <akim@epita.fr>

13559 * tests/fortran.at (GNU Fortran 77): there.
13560 * doc/autoconf.texi (autoconf Invocation): Fix the example:
13561 AC_TRY_RUN is about compilation, not shell commands.

13604 Don't compute at_srcdir nor at_top_srcdir.
13606 * tests/tools.at: Hence use top_srcdir.
13608 * tests/Makefile.am, tests/autoconf, tests/autoheader,

13666 * tests/Makefile.am (package.m4): Remove.
13668 2001-09-22 Akim Demaille <akim@epita.fr>
13670 Rely on `$LINENO' when possible instead of `__oline__'.

13689 2001-09-21 Akim Demaille <akim@epita.fr>
13691 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
13692 Suggested by Jim Meyering.
13694 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13696 * lib/autoconf/programs.m4: Use extensions listed in
13697 $ac_executable_extensions when looking for programs.

13726 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13728 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

13735 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13737 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
13738 already have $file). Set output files to binary mode (helps avoid
13739 CR issues on DOSish systems).
13741 2001-09-19 Akim Demaille <akim@epita.fr>
13743 * lib/autotest/general.m4: Englishoes.
13744 From Tim Van Holder and Alexey Mahotkin.
13746 2001-09-18 Paul Eggert <eggert@twinsun.com>
13748 * doc/autoconf.texi (Common Shell Constructs): New node,
13749 documenting AS_DIRNAME.
13750 (Limitations of Usual Tools): Refer to it when discussing dirname.
13751 Also, update discussion of POSIX standard to reflect latest draft.
13753 * lib/autoconf/c.m4:
13754 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
13756 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13757 Do not pass a first argument with leading '-'
13758 to expr, by parenthesizing initial integers that might be negative.
13760 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
13761 now merely checks whether it is an error to pass an argument
13764 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
13765 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
13766 whether it is a (compile-time) error to pass an argument to
13767 getpgrp. This simpler test supports the revised documentation,
13768 and is all that AC_FUNC_GETPGRP's users really need.
13770 2001-09-18 Akim Demaille <akim@epita.fr>
13772 * doc/autoconf.texi (Limitations of Make) <$<>: New.

13782 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
13784 Add test for AS_BASENAME.
13785 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
13786 added test. It now correctly handles /1/2/3/, returning '3' not ''.
13787 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
13788 * tests/base.at: Fixed the expected responses. The old ones were
13790 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
13791 the documentation claims it should (and how it behaved in 2.13).
13793 2001-09-18 Akim Demaille <akim@epita.fr>
13795 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
13796 the AC_CONFIG_COMMANDS invocation.
13797 This also solves the name clash problems.
13798 Don't set the package's ID.
13799 * lib/m4sugar/Makefile.am (version.m4): Revamp.
13800 No longer to be shipped.
13801 (version.in): Remove.
13802 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
13803 * lib/autoconf/status.m4: Adjust.
13804 Use `m4_PACKAGE_STRING'.
13805 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
13806 the only optional argument is the name of the test suite.
13807 Expect `package.m4' to define the package signature.
13808 * lib/autom4te.in (Autotest): Add `package.m4?'.
13809 * tests/Makefile.am (package.m4): New.
13810 * tests/suite.at: ifnames is a victim.
13812 2001-09-18 Akim Demaille <akim@epita.fr>
13814 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
13815 AC_LIBSOURCE, AC_CONFIG_FILES.
13816 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
13817 program version string doesn't match the package's.
13818 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
13821 2001-09-17 Paul Eggert <eggert@twinsun.com>
13823 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13824 Allow expression to return any value that can fit into unsigned long
13825 (not int, as before). Check for output errors.
13827 2001-09-17 Bruno Haible <haible@ilog.fr>
13829 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13830 Always include <stdio.h> and <stdlib.h>. Evaluate
13831 the expression in an extra function before these includes. Call
13832 fprintf "%d" only after ensuring the argument is of type 'int'.
13833 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
13835 2001-09-17 Paul Eggert <eggert@twinsun.com>
13837 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
13838 or CFLAGS=-O5. In that case, the linker has a relaxed view of
13839 fatal errors, and AC_CHECK_LIB causes it to include libraries even
13840 when they don't exist.
13842 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
13843 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
13846 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
13847 version with the version used by fileutils 4.1, except use
13848 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
13851 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
13853 2001-09-13 Akim Demaille <akim@epita.fr>

13859 2001-09-13 Akim Demaille <akim@epita.fr>
13861 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
13862 m4_defn'ing is valid.

13877 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
13879 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
13880 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
13881 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
13882 AT_tests_all for consistency.
13884 (AT_VICTIMS): Similar to AT_KEYWORDS.

13887 2001-09-13 Akim Demaille <akim@epita.fr>
13889 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
13891 2001-09-13 Akim Demaille <akim@epita.fr>
13893 * lib/autotest/general.m4 (AT_INIT): Create and remove
13894 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
13895 test suites can cohabit.
13897 2001-09-13 Akim Demaille <akim@epita.fr>

14008 the maintainer is dumb enough to do that...
14010 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14011 excellence in M4 quotation: consider `__file__' is active.

14084 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

14191 find the executables for it.

14193 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14195 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14196 indeed related to running the test suite, while passing
14197 --autoconf-dir and others is related to running non installed

14200 * tests/autoscan: New.
14201 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

14220 2001-08-29 Akim Demaille <akim@epita.fr>

14378 (AMTAR): Help automake define it.
14379 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
14380 needed, 1.5 can have a macro and a target with the same name.

14609 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

14627 * doc/autoconf.texi: Work around Texinfo buglets.
14628 (Transformation Rules): One example is enough, users are expected

14634 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

14687 autom4te.cache (it's a directory, not a file.
14688 * Makefile.am: Ditto (but maintainer-clean-local).
14690 2001-08-15 Akim Demaille <akim@epita.fr>
14692 * bin/autom4te.in (@m4_warning): New.
14693 (&handle_m4): Use it.
14694 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

14764 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
14766 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
14767 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
14768 * doc/autoconf.texi (C Compiler Characteristics): Update
14769 documentation for AC_C_BIGENDIAN.
14771 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
14773 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
14774 magic values from an object file when cross-compiling.
14775 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
14777 2001-08-10 Akim Demaille <akim@epita.fr>
14779 * bin/autom4te.in (&handle_output): Don't use `grep' with side
14781 Suggested by Russ Allbery.
14783 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
14785 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
14786 current $prefix to the sub-configures.
14788 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
14790 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
14791 extension (needed on BeOS). Reported by Guido van Rossum.
14793 2001-08-09 Akim Demaille <akim@epita.fr>
14795 * bin/autom4te.in ($icache): Load it only if older than autom4te.
14797 2001-08-07 Akim Demaille <akim@epita.fr>
14799 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
14801 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
14802 No need to remove the files before and after the each test, before
14803 each test and at the end of the suite is enough.
14804 Display only the children `times', not the shell's.
14805 If the test failed or was skipped, at-times is not available.
14807 2001-08-07 Akim Demaille <akim@epita.fr>
14809 Always produce testsuite.log, including when there are no
14810 failures. This helps getting information on skipped tests, and
14811 duration of the tests. Err, implement the latter btw.
14813 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
14814 Dump information on the first run of each test.
14815 (AT_CLEANUP): Create `at-times' containing the duration of the
14818 2001-08-07 Akim Demaille <akim@epita.fr>
14820 The use of `dumpstat' revealed that `len' was used although it
14821 should not. m4_text_wrap was using it, but in the Autoconf world
14822 where it is legal. Hence (i) test M4sh in its own world, not
14823 Autoconf's, and (ii), ahem, fix the bug :)
14825 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
14826 does not like `' instead of [].
