644 BSD behavior on binary input.
646 Minor testsuite improvements.
647 * lib/autotest/general.m4 (AT_INIT) <PREPARE_TESTS>: Use fewer
648 forks when sanitizing PATH. Always output machine information,
649 not just when atconfig was located.
651 Add 'testsuite -C dir'.
652 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
654 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
656 <DEFAULTS>: Delay computation of variables based on $at_dir...
657 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
658 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
659 <PARSE_ARGS>: Parse new option.

670 build-aux/texinfo.tex: Sync from gnulib.
671 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
674 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
676 * doc/autoconf.texi (Particular Programs): Do not mention the
677 Autoconf version in which the AC_PROG_INSTALL change was done.
678 Suggested by Paul Eggert.
680 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
682 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
683 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
684 mode, we change to the source directory, also set $ac_pwd so we
685 do not go back to the build tree for the next config subdir.
686 * tests/torture.at (Deep Package): Extend test to contain two
687 config subdirs on the top level.

720 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
721 check_SCRIPTS. Building the wrappers for `all' allows help2man
722 to use them for the manpages.
723 Report by Benoit Sigoure.
725 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.

740 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
741 (m4_require): Use m4_do, not m4_join.
743 Fix some whitespace tests on cygwin.

745 font-lock. Create $TMPDIR before it might be used.
747 Fix spurious testsuite failure with M4 1.4.11.
748 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
751 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)

753 (m4_require): Avoid extra macro calls.
755 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

759 Do not pass top_srcdir to configure scripts in testsuite.
760 * tests/autotest.at (srcdir propagation): Copy install-sh to
762 (my only test): Drop setting of `top_srcdir'.
763 * tests/base.at (Input/Output): Likewise.
764 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
765 config.guess, and config.sub to test source tree.
766 Drop AC_CONFIG_AUX_DIR setting.
767 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
768 * tests/torture.at (Substitute a 2000-byte string): Drop
769 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
770 (Substitute a newline, datarootdir workaround): Likewise.
771 (Define a newline): Adjust for linenumber changes in configure.ac.
772 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
774 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
775 if `pwd` contains whitespace.
777 Quote $abs_top_srcdir in tests.
778 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
779 * tests/tools.at (Syntax of the shell scripts): Likewise.
781 * tests/m4sh.at (LINENO): Quote $0.
783 Fix testsuite program wrapper for whitespace in `pwd`.
784 The problem here is that the usual mantra is that command
785 variables can contain arguments, thus we cannot just escape
786 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
787 $top_builddir/tests directory early in $PATH, so that the
788 wrappers are found by their plain name.
789 * tests/wrapper.as: Put $testdir early in $PATH.
790 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
792 Proper config.status --file/--header and $srcdir escaping.

798 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
800 Fix Autotest for whitespace in `pwd`.
801 * lib/autotest/general.m4 (AT_INIT)
802 <at_func_create_debugging_script, Driver Loop>:
804 * tests/autotest.at (whitespace in absolute testdir): New test.
806 * lib/autom4te.in: Quote @datadir@.
808 Proper file name escaping in Autoconf programs and Perl modules.
809 This includes escaping of characters special to the shell
810 as well as special to Perl, e.g., leading `<' or `>'.
811 For example, when $file starts with `>', `open ">$file"'
812 wrongly tries to append to a different file.
813 * bin/autoconf.as: Fix quoting for autom4te options.
814 * lib/Autom4te/General.pm (shell_quote): New function, taken
815 from coreutils, written by Jim Meyering.
817 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
819 * bin/autoreconf.in (parse_args): Likewise.
820 * bin/autoscan.in (main): Likewise.
821 * bin/autoupdate.in (main): Likewise.
822 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
823 * bin/ifnames.in: Likewise, XFile usage fixes.
824 * tests/tools.at (autom4te and whitespace in file names): Extend
825 test. Test twice, with special characters allowed on w32, and the
826 rest. Test leading and trailing whitespace, for `open_quote'.
827 (autotools and whitespace in file names): New, analogous test.
828 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
829 by Russ Allbery and Eric Blake.
832 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
833 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
834 * lib/Autom4te/FileUtils.pm (open_quote): New function.
835 (update_file, contents): Use it.
837 * Makefile.am (autom4te-update): Rewrite for git.
839 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
841 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
844 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
845 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
847 2007-12-04 Eric Blake <ebb9@byu.net>
849 Manually resync with gnulib, since 'make cvs-update' no longer works.
850 * build-aux/config.guess: New upstream version.
851 * build-aux/config.sub: Likewise.
853 When using older automake, don't downgrade build-aux/texinfo.tex.
854 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
855 * doc/Makefile.am (TEXINFO_TEX): Add.
857 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
859 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
860 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
861 #undef as this runs afoul of our new way of creating config.h.
862 Problem reported by Jim Meyering in
863 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
865 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
867 Fix autom4te for unusual characters in input file names.
868 * bin/autom4te.in (files_to_options): Quote active characters
870 * tests/tools.at (autom4te and white space in file names):
873 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
874 Document that Tru64 awk always splits $0.
876 2007-11-24 Stepan Kasal <kasal@ucw.cz>
878 * lib/autotest/general.m4 (AT_INIT): Do not extract the
879 `#AT_STOP_...' line at the end of each test.
881 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
883 * lib/autotest/general.m4 (AT_INIT): For awk line number
884 extraction script, ensure `$at_group' has a defined value
885 even for the empty set, and properly quote its usage inside
888 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
890 * doc/autoconf.texi (Shell Functions): New chapter. Document
891 IRIX sh $0 issue in functions, move content from ...
892 (Portable Shell): ... here.
893 (Shell Script Compiler): Note that shell functions are not
894 totally unportable any more.
896 2007-11-22 Stepan Kasal <kasal@ucw.cz>
897 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
899 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
900 extracting the line numbers of the last needed test.
902 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
904 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
907 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
909 Fix IRIX testsuite debugging failures: $0 in functions.
910 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
911 Do not use $0 inside a function, as IRIX sh will set that to the
912 function name rather than the script invocation name.
914 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
915 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
917 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
918 to extract test scripts.
919 (AT_INIT): Extract and cache test script line numbers.
921 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
923 * lib/autotest/general.m4: Revert 2007-11-15 patch and
924 subsequent fixups; the awk -> here-document conversion trashes
925 performance too much with AIX sh.
927 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
929 * tests/local.at: Do not test m4, perl with AT_TESTED.
931 Diagnose and guard against write errors dealing with config.status.
932 The general idea is this: all write failures from `configure'
933 writing `config.status' are indicated by $ac_write_error, which
934 is only checked at the end. This is safe because config.status
935 code is not executed before the file is complete. Other write
936 failures, be they inside config.status, or in sub shell/awk
937 scripts spawned from configure or config.status, typically need
938 earlier checking, as their results are used right afterwards.
939 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
940 before writing config.status, check afterwards.
941 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
942 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
943 Set `ac_write_error' for write failures to config.status. Barf
944 upon write failures to temporary files.
945 Adjust note about closing and reopening the here-document.
946 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
947 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
948 reopening the here-document.
949 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
950 Ensure `ac_write_error' does not escape into config.status.
951 Also, add a couple of code paths not yet exercised in the test
952 suite: a config file with input from stdin, and a config header
954 Suggestion for catching write errors by Bruno Haible.
956 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
958 Avoid error with Tru64 awk and testsuite lines with many words.
959 * lib/autotest/general.m4 (AT_INIT): In the awk script that
960 reads the testsuite, set the field separator to an unusual value,
961 in order to not run over the limit of 199 fields. Tru64 4.0D awk
962 even splits the input if $i, i>0, was never accessed in the script.
964 Revert 2007-10-17 change.
965 * TODO: Multiline args in config files and headers mean something
966 different and are not fixed, see
967 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>

972 2007-11-16 Stepan Kasal <kasal@ucw.cz>
974 AC_*_TOOL does not canonicalize the prefix
975 * doc/autoconf.texi (Generic Programs): Do not say that
976 the *_TOOL macros canonicalize, they simply use the `host_alias'.

1063 Use ":;{" shorthand.
1064 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1066 2007-11-12 Jim Meyering <meyering@redhat.com>
1068 Add more non-srcdir build support.
1069 * GNUmakefile (dummy): Split a long line.
1070 Add -v option to autoreconf invocation.
1072 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1073 * GNUmakefile (dummy): Remove INSTALL.
1075 Remove racy commands to build scripts in bin/ and tests/.
1076 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1077 are guaranteed to be built, remove the rules that tried to build
1078 them. Before, with a parallel build, these rules could lead to
1079 two processes writing tests/wrapper.in concurrently.
1081 Build in man/ only *after* building in bin/ and tests/.
1082 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1083 in both bin/ and tests/.
1085 Accommodate non-srcdir build-from-checkout.
1086 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1087 Use git's --git-dir=$srcdir/.git option.
1088 Add quotes, in case tarball_version_file contains shell meta-characters.
1089 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1090 * configure.ac: Pass "." to git-version-gen.
1092 Avoid spurious test failures due to version skew.
1093 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1095 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1097 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1098 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1099 Remove conftest.dSYM directory.
1100 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1101 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1102 Remove `conftest.*' recursively.
1103 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
1104 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1106 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
1108 Report and analysis by Jeff Squyres and Peter O'Gorman.
1110 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
1112 Fix typos in variable names.
1113 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
1115 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
1117 Document that $((expression)) is not portable.
1118 * doc/autoconf.texi (Shell Substitutions): Here.
1120 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1122 Ignore configure --help* errors due to LINENO-impaired shells.
1123 * tests/torture.at (Configuring subdirectories, Deep Package):
1124 In the --help* tests in read-only trees, make `.' temporarily
1125 writable again for the `stderr' file, and ignore errors due to
1126 the attempt to write configure.lineno.
1127 Report by Patrick Welche.
1129 2007-11-10 Jim Meyering <meyering@redhat.com>
1131 Generate package.m4 in build-dir, not srcdir.
1132 * tests/Makefile.am (package.m4): Adjust target.
1133 Don't redirect directly to $@.
1134 (CLEANFILES): Add package.m4.
1135 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1137 When running $(AUTOTEST), search "." before searching $(srcdir).
1139 Avoid a race condition that would make parallel "distclean" fail.
1140 * tests/Makefile.am (distclean-generic): Replace the default,
1141 automake-provided rule with an identical one, but with an additional
1142 dependency on distclean-local. Simply adding the dependency would
1143 cause automake not to emit the rule at all.
1144 * BUGS: Building with -jN works, now.
1146 Distribute git-version-gen.
1147 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1148 since GNUmakefile is distributed, and requires it for dist* rules.
1150 Remove two more generated files from version control.
1151 * INSTALL: Remove generated file.
1152 * lib/autoscan/autoscan.list: Remove generated file.
1154 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1156 * GNUmakefile (PATH): Remove stray apostrophes; they become
1157 part of PATH, which isn't wanted here.
1159 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1161 New config files output variable `top_build_prefix'.
1162 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1164 * doc/autoconf.texi (Preset Output Variables): Document it.
1166 Report by Bob Friesenhahn.
1168 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1169 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1170 function, to parametrize arithmetic with expr vs. the shell.
1171 Use it where possible.
1172 Suggestion by Benoit Sigoure.
1174 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1176 Adjust the documentation of autotest WRT atlocal.
1177 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1178 when using Automake, to write a rule to produce atlocal, since it's
1179 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1180 distributed, not atconfig.in.
1182 2007-11-04 Eric Blake <ebb9@byu.net>
1184 Update list information.
1185 * README: Mention new autoconf-commit list.
1186 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
1188 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1190 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
1192 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1194 * build-aux/.gitignore: Ignore mkinstalldirs.
1196 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1198 2007-11-03 Jim Meyering <meyering@redhat.com>
1200 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1201 * build-aux/git-version-gen: This syncs from coreutils.
1203 Adjust the build procedure so "make check" works reliably.
1204 * README-hacking: Include an extra step between "make" and
1205 "make check" to ensure that the latter passes.
1207 Use just-built tools, when possible.
1208 * GNUmakefile (PATH): Set and export here, ...
1209 (dummy): ... rather than here.
1211 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1212 and Andreas Schwab <schwab@suse.de>
1214 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
1217 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1219 * configure.ac (AC_PREREQ): Require version 2.60, for
1220 AC_PROG_SED, AC_PROG_GREP.
1222 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
1223 and Jim Meyering <meyering@redhat.com>
1224 and Andreas Schwab <schwab@suse.de>
1225 and Eric Blake <ebb9@byu.net>
1227 Document a bug in GNU Bash with compound commands and redirections.
1228 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
1229 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
1232 2007-11-03 Eric Blake <ebb9@byu.net>
1234 Support m4 1.4.5 in testsuite.
1235 * tests/torture.at (Define a newline): Exclude line numbers in
1237 Reported by Ralf Wildenhues.
1239 2007-11-03 Jim Meyering <meyering@redhat.com>
1241 Remove automake-provided files from version control.
1242 * build-aux/elisp-comp: Remove file.
1243 * build-aux/install-sh: Remove file.
1244 * build-aux/missing: Remove file.
1245 * build-aux/mdate-sh: Remove file.
1246 * build-aux/.gitignore: New file.
1247 Suggestion from Ralf Wildenhues.
1249 2007-11-03 Eric Blake <ebb9@byu.net>
1251 Adjust version comparison to account for git snapshot numbers.
1252 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
1253 component separator.

1255 <m4_version_compare>: Document this change.
1256 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
1258 2007-10-30 Bruno Haible <bruno@clisp.org>
1260 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1261 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1262 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1263 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1264 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1265 Suggested by Paul Eggert.
1267 2007-10-28 Jim Meyering <meyering@redhat.com>
1269 * README-hacking: Autoconf, Automake, and Perl are required to build.
1270 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1272 2007-10-28 Jim Meyering <meyering@redhat.com>
1274 README-hacking: Recommend running autoreconf -vi.
1275 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1276 so that we use just-built tools when they're available.
1277 Suggestions from Ralf Wildenhues.
1279 2007-10-28 Jim Meyering <meyering@redhat.com>
1281 Make inter-release --version output more useful.
1283 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1284 which indicates that it is built using the 19th change set
1285 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1286 is a prefix of the commit SHA1.
1287 * build-aux/git-version-gen: New file.
1288 * configure.ac: Run it to set the version.
1289 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1290 * Makefile.am (dist-hook): Arrange so that .version appears only
1291 in distribution tarballs, never in a checked-out repository.
1292 * .gitignore: Add .version here, too. Just in case.
1293 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1294 not configure.ac, now that the version number changes automatically.
1296 Ensure that $(VERSION) is up to date for dist-related targets.
1297 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1298 git-version-gen doesn't match $(VERSION), but only for dist targets.
1300 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1302 Fix `Deep Package' failure with a configure script early in PATH
1303 * tests/torture.at (Deep Package): Add `.' early in PATH.

1311 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
1312 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
1313 * README-hacking: New file: how to build from just-checked-out sources.
1315 2007-10-23 Eric Blake <ebb9@byu.net>
1317 Improve corner case of m4_expand.
1318 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more

1321 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
1324 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>
1326 * doc/make-stds.texi: Update from gnulib.
1328 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1329 and Eric Blake <ebb9@byu.net>
1331 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
1332 problem reported by Bruno Haible in
1333 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
1335 2007-10-22 Eric Blake <ebb9@byu.net>
1337 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
1340 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1342 Don't check for bug in HP-UX 11.00 cpp.
1343 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
1344 Use -1ull rather than -1u, since that causes problems with gnulib; see
1345 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
1347 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1352 (Multiline parenthetical command substitution): Fix typos in
1355 2007-10-21 Eric Blake <ebb9@byu.net>
1357 * configure: Regenerate.
1359 2007-10-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1361 Fix config status generation with Tru64 ksh.

1363 escaping of backslash in here-documents.
1365 Fix `Deep Package' test failure on FreeBSD.
1366 * tests/torture.at (Deep Package): Do not add `.' to $PATH
1367 unnecessarily. Do not try running `/bin/sh configure' with a
1368 configure script to be found in $PATH, if the shell does not do
1369 this resolution. Fixes test failure on FreeBSD.
1371 Fix config header generation with AIX awk.
1372 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
1373 script, use helper array D_is_set, as `" 0"' does not evaluate
1374 to true for AIX awk.
1376 2007-10-21 Eric Blake <ebb9@byu.net>

1411 * lib/autotest/general.m4 (BANNERS): New named diversion.
1412 (TESTS_END): Diversion no longer used.
1413 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
1414 shell function, which prints only as needed, using an associative
1415 array of banner text from a special diversion.
1416 <PARSE_ARGS_END>: No longer need awk to find banners.
1417 <TESTS>: Banners are no longer processed by main driver loop, so
1418 we no longer need case statement.
1419 (AT_BANNER): Rewrite to populate new diversion.
1420 (AT_SETUP): Each test invokes its own banner. No output is needed
1421 to the TESTS diversion.

1447 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Fix
1448 duplication bug by using new macro.
1449 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
1450 programs with stdin redirected, so programs that don't
1451 understand --version won't try to behave interactively.
1452 * tests/autotest.at (Tested programs): Catch this bug.
1453 * tests/m4sugar.at (m4@&t@_append): Test new macro.

1511 Fix `configure --help=recursive' in unconfigured/read-only trees.
1512 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Avoid errors when `.'
1513 is not writable, use 'cp -p' in this case, in the hope that it
1514 will not actually be needed. Still try removing files, in case
1515 of other write errors.
1516 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): For ac_confdir,
1517 use $as_myself, not $0.
1518 (_AC_INIT_HELP): For --help=recursive, if the subdir does not
1519 exist, try again in the the source tree. This change assumes
1520 that the subpackage configure script is capable of running
1521 --help=recursive in the source tree.
1522 * tests/torture.at (Configuring subdirectories, Deep Package):
1523 Adjust tests to expose both issues, also try invocation as
1524 `sh configure ...' and plain `configure ...' with PATH adjusted.

1543 * lib/m4sugar/m4sugar.m4 (m4_apply, m4_count, m4_dquote_elt)
1544 (m4_echo, m4_make_list): New documented macros.
1545 (_m4_quote, _m4_shift2): New helper macros.

2548 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
2549 about Solaris /bin/printf '%010000x' 123. Problem reported by
2552 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
2554 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
2555 for a.* when searching for executables, as this prevents users
2556 from having files like a.c. Problem reported by Ralf Wildenhues in:
2557 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
2558 This fixes a problem introduced on 2000-12-19.
2560 2007-04-26 Paul Eggert <eggert@cs.ucla.edu>
2562 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
2563 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
2566 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
2568 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
2569 AC_CHECK_TYPE, AC_CHECK_TYPES.
2570 * doc/autoconf.texi (Generic types): C types must be type-names
2571 (the C terminology), not type-ids (the C++ term). C++ types
2572 must not be anonymous.
2573 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
2574 for C++; this drops support for anonymous struct and union types,
2575 which were problematic anyway.
2576 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
2579 2007-04-12 Jim Meyering <jim@meyering.net>
2581 * doc/autoconf.texi (Libraries): Typo fix: insert missing "in".

2591 * doc/autoconf.texi (Generic Types): Document the restrictions
2592 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
2593 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
2594 with objects too. Document the restrictions on its use.
2595 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
2596 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
2597 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
2598 works but the latter doesn't, then it's a valid type.
2599 This lets people use function types and so forth.
2600 For C++ there doesn't seem to be a simple solution, so leave it alone.
2601 (AC_CHECK_SIZEOF): Allow argument to be a variable.
2602 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
2603 AC_CHECK_TYPE; that wasn't documented or necessary.
2605 2007-04-11 Stepan Kasal <kasal@ucw.cz>
2607 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
2608 when cross-compiling.

2628 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
2629 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
2630 default still has the problem. Problem reported by Bruce Korb.

2645 command and case statements to make it a bit clearer and describe
2648 2007-03-23 Paul Eggert <eggert@cs.ucla.edu>
2650 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
2651 checks for unsigned long long int.
2653 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
2655 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
2656 nonstandard grep R.E. escape sequences.
2658 2007-03-17 Jim Meyering <jim@meyering.net>
2660 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
2661 (Limitations of Usual Tools): Also list \< and \>, and mention that
2662 HP-UX's grep, like the one from Solaris, does not support that syntax.
2664 2007-03-09 Stepan Kasal <kasal@ucw.cz>
2666 * doc/autoconf.texi (Specifying Names): `--host' does not
2667 change the build type.
2669 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
2671 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
2672 suggests AC_CONFIG_HEADERS.

2682 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
2683 universal binaries. Problem reported by Elias Pipping.
2685 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
2687 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
2688 * doc/autoconf.texi (C Compiler): Document this. There is a new
2689 extra argument ACTION-IF-UNIVERSAL.
2690 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
2691 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
2692 Reindent for sanity's sake.

2702 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2704 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
2705 status of rm so we know when it failed.
2706 If cleaning of test dir failed before running the test, warn.
2707 Output the line separator in verbose mode before the warning
2708 to make clear the warning belongs to the following test.
2710 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>

2735 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
2736 input from /dev/null in awk test, so even Solaris /usr/bin/awk

2773 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
2774 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
2775 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
2776 substitution will still be done by the special code.
2777 Report by Jim Meyering.

2798 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2800 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
2801 early on the reader side, drop stderr of the input to avoid
2802 `broken pipe' error output; this may happen even with shell
2803 builtin `echo' of some bash versions. Reports by Ian Macdonald
2804 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
2806 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2819 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
2820 * doc/autoconf.texi (Signed Overflow Examples): Give more
2821 discussion about the allow_superuser_privileges example,
2822 and change it a bit to make things clearer.
2823 (Optimization and Wraparound): Clarify whether the compiler
2824 will generate an infinite loop for the example derived from
2825 Autoconf's mktime test.
2826 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
2827 Also, clarify unsigned multiplication overflow.
2829 2007-01-04 Eric Blake <ebb9@byu.net>
2831 * bin/Makefile.am (RELEASE_YEAR): New macro.
2832 (edit): Use it to supply correct copyright year to scripts.
2833 * bin/autoconf.as (version): Use it.
2834 * bin/autoheader.in ($version): Likewise.
2835 * bin/autom4te.in ($version): Likewise.
2836 * bin/autoreconf.in ($version): Likewise.
2837 * bin/autoscan.in ($version): Likewise.

2839 * bin/ifnames.in ($version): Likewise.
2841 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
2843 * doc/autoconf.texi (Integer Overflow): Revised based on today's
2844 feedback. The most important changes document what happens when
2845 you convert an out-of-range value to a signed integer type, and
2846 say that (sum < a) != (b < 0) reliably detects overflow when sum =
2849 * doc/autoconf.texi (Integer Overflow): Greatly expand and
2850 rewrite, taking notions from the recent discussion on the gcc and
2851 autoconf mailing lists; please see
2852 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
2853 and follow the many links.
2854 (Integer Overflow Basics, Signed Overflow Examples):
2855 (Optimization and Wraparound, Signed Overflow Advice):
2856 (Signed Integer Division): New sections.
2858 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
2860 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
2861 preprocessor macro arguments in traced name.
2862 * doc/autoconf.texi (Defining symbols): Document longstanding
2863 support for AC_DEFINE-ing macros with arguments, and document
2864 behavior when the same variable has multiple AC_DEFINEs.
2865 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
2866 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
2867 macros directly, giving much shorter and simpler code.
2869 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
2871 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
2872 space before "$ac_configure_args" to prevent a 'config.status
2873 --recheck' failure if ac_configure_args doesn't contain a leading
2874 space. This works around a problem with the XEmacs configure.ac,
2875 which uses the (undocumented) ac_configure_args variable
2876 inconsistently with Autoconf.
2878 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
2880 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
2881 Include <limits.h>, and use its INT_MAX to rewrite the
2882 j loop so that it does not overflow 'int'. Problem reported by
2884 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
2885 Play it safe by shifting left by 1 rather than multiplying by 2,
2886 as GCC is less likely to optimize this away when the value
2887 is signed (when it assumes overflow leads to undefined behavior).
2888 Also, don't assume time_t uses two's complement.
2890 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2892 * tests/torture.at (Substitute a 2000-byte string): Avoid using
2893 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
2894 dumps core on it. Report by Tim Rice.
2896 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2898 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
2899 --disable-option-checking to --help output even when
2900 AC_PRESERVE_HELP_ORDER is not used.
2901 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
2902 --with argument, rather than argument with [-.] replaced by
2904 * NEWS: Fix typo in previous change; the news was in the
2907 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2909 * NEWS: Warnings are now generated by default for unknown
2910 --enable-* and --with-* options.
2911 * doc/autoconf.texi (Option Checking): Renamed from
2912 (Configure Option Checking). Tighten up the wording a bit.
2913 (External Software, Package Options): Cross-reference to Option
2914 Checking, and use this to shorten our section.
2915 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
2916 "$x" to test "x$foo" != x.
2917 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
2918 Don't warn if $enable_option_checking is "no".
2919 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
2920 ac_unrecognized_opts to the empty string.
2921 Don't echo the unrecognized opts, as this might mishandle
2922 backslashes or leading -.
2923 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
2924 usage next to the other --disable-FEATURE options in the
2927 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2929 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
2930 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
2931 Print warning for unrecognized --with and --enable options
2932 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
2933 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
2934 Disable option checking when subdirs are configured.
2935 (AC_OUTPUT): If warnings are enabled, print warning about
2936 unrecognized --with and --enable options at the end of
2937 the configure output (as well as at the beginning).
2938 * doc/autoconf.texi (Option Checking): New node.
2939 Document new option warning functionality.
2941 2006-12-16 Eric Blake <ebb9@byu.net>
2943 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
2944 * NEWS: Start news for current version.
2946 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
2948 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2949 Define HAVE_GETMNTENT to 1, not to the empty string.
2950 Problem originally reported by Jochen Friedrich in
2951 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
2953 This change prompted by a problem report by Andrey Simonenko in
2954 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
2955 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
2956 object-like macros only, in the traditional portable character
2958 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
2959 Warn about attempts to define things that are not identifiers.
2960 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
2961 awful hack that AC_DEFINEd macro names containing parentheses.
2963 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
2965 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
2966 too drastic, even if Texinfo in theory requires it for info mode.
2968 (config.status Invocation): Renamed back from Recreating a
2970 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
2971 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
2973 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2975 * NEWS: Version 2.61a.
2977 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2978 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2980 * NEWS: Document changes with echo and printf, and the lack
2981 of limits on the total size of multi-line values of substituted
2982 variables, and the AC_FUNC_FSEEKO fix.
2984 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
2986 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
2987 Writing configure.ac.
2988 (Autoconf Input Layout): Renamed from configure.ac Layout.
2989 (Recreating a Configuration): Renamed from config.status Invocation.
2990 (Obsolete Recreation): Renamed from Obsolete config.status Use.
2991 (acconfig Header): Renamed from acconfig.h.
2992 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
2993 (Writing Testsuites): Renamed from Writing testsuite.at.
2994 (Autom4te Cache): Renamed from autom4te.cache.
2996 * BUGS: Remove mention of VPATH problem, since it's now documented
2997 not to be a bug in the Autoconf build procedure itself, but rather
2998 a problem with the proprietary `make' programs.
3000 * doc/autoconf.texi (Build Directories): Add a cross reference
3003 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3004 * doc/standards.texi: Sync from gnulib.
3006 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:

3009 generated automatically.
3011 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3013 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3014 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3015 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3017 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3019 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3020 `CEOF$ac_eof' special marker, the awk script cannot contain a
3021 line matching `^CEOF', so this is not needed any more.
3022 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3023 special marker in the test.
3025 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3027 * tests/tools.at (autom4te preselections): Use `find -newer';
3028 remove one of the sleeps.
3030 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3031 more readable, using ...
3032 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3034 * doc/autoconf.texi (autoheader Invocation): Do not double-
3035 quote the parameter of `AH_BOTTOM' in the example.
3037 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3039 * doc/autoconf.texi (Configuration Headers): Remove the
3040 example with multiple input files.
3041 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3042 multiple input files.
3044 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3046 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3047 creating the awk substitution script, handle one input line at a
3048 time, so that the maximum length of a substituted (multi-line)
3049 value is not limited by the size of the sed pattern space.
3050 The trade-off is a slightly repetitive sed script.
3051 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3052 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3053 * tests/torture.at (Substitute a 2000-byte string): Increase the
3054 test with several long lines, they should not be caught by sed
3057 * tests/tools.at (autom4te preselections): New test, to flag
3058 entries missing from autom4te.cfg.
3059 Report by David Byron <dbyron@hheld.com>.
3061 * tests/torture.at (Substitute a 2000-byte string): Actually use
3062 AC_PROG_AWK, so the last change works as intended.
3063 (Substitute and define special characters): Likewise.
3064 (Substitute a newline): Likewise.
3066 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3067 instead of `awk' consistently.
3068 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3069 * tests/torture.at (Torturing config.status): Test both the
3070 result of AC_PROG_AWK and plain awk.
3071 (Substitute a 2000-byte string): Likewise.
3072 (Substitute and define special characters): Likewise.
3073 (Substitute a newline): Likewise.
3075 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3077 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3078 can be assigned to a function pointer. Problem reported by
3079 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3080 part of a patch by Ralf Wildenhues in that same bug report.
3082 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3084 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3085 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3087 2006-12-01 Eric Blake <ebb9@byu.net>
3089 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3090 cross-compiling from cygwin to mingw.
3091 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3092 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3093 to lib/autoconf/c.m4.
3095 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3097 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3098 string for more reliable failure. Wrap the entire test that
3099 causes the broken Solaris printf to dump core, in a subshell,
3100 so the segmentation fault message is reliably suppressed.
3101 Fix shell expansion errors by using /usr/ucb/echo always;
3102 avoid an error on systems without it by another subshell.
3103 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3104 subshell-$as_echo to `as_echo', for better error message.
3106 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3108 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3109 `BASH_SOURCE' contain a newline, set them to empty, as they may
3112 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3114 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3115 years and is too hard to maintain now. The last straw was
3116 reported by Jerker Baeck in
3117 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3118 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3119 * doc/autoconf.texi (Particular Functions): Move
3120 AC_FUNC_SETVBUF_REVERSED from here...
3121 (Obsolete Macros): ... to here. Say that it does nothing now.
3122 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3123 Turn into (almost) a no-op.
3125 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3127 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3128 These macros are obsolescent and new applications shouldn't need them.
3129 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):

3136 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3138 * doc/autoconf.texi (Setting Output Variables): Mention that
3139 @VAR1@VAR2 has unspecified behavior. Problem reported by
3141 * NEWS: Mention this.
3143 * Makefile.am: Put only a single '#' into the copyright notice,
3144 so that it's also present in the output file. Standardize wording
3145 in makefile copyright notices to match GNU coding standards.
3146 * bin/Makefile.am: Likewise.

3159 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3161 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3162 in the sed script that mangles the awk script: delete up to the
3163 first exclamation mark only.
3164 * tests/torture.at (Substitute and define special characters):
3167 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3169 Rewrite config files generation: avoid quadratic growth in
3170 the number of substituted variables by using awk instead of sed
3171 for the bulk of the substitutions.
3172 * NEWS: Mention this.
3173 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3174 forbidden in the output (and thus input) file.
3175 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3176 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3177 generate just one large awk script for substitutions,
3178 eliminating much of the earlier complexity, while adding some
3179 new complexity. Only expand the substitution templates at
3180 configure time, for smaller configure script size. If
3181 _AC_SUBST_FILES are used, test 'awk' for working getline support
3182 at config.status time. If absent, interpolate through the
3183 shell. The awk script was written with much help
3184 from Paolo Bonzini and Paul Eggert.
3185 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3186 (_AC_SED_FRAG_NUM): Likewise.
3187 (_AC_SUBST_CMDS): Renamed from...
3188 (_AC_SED_CMDS): ...this.
3189 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3190 * tests/torture.at (Substitute a 2000-byte string): Also
3191 substitute a line with 1000 words, and a variable with several
3193 (Substitute and define special characters): Test awk special
3194 characters, and put substitution input strings `@foo@' in the
3195 output, to test that no recursion happens; test several other
3196 combinations from Paolo Bonzini.
3198 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3200 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3201 that replaced echo with AS_ECHO where this wasn't necessary.
3202 Problem reportd by Ralf Wildenhues.
3203 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3204 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3205 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3207 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3209 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3211 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3213 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3214 that traditional Awk lacks 3-arg "split". It has it.
3215 Mention that FS must be a single character, and a few other
3216 99-byte limits of traditional Awk.
3217 Mention that if (i in a) doesn't work with traditional Awk.
3219 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3221 * tests/autotest.at (BSx641-newline in command):

3223 (Newline-CODE-BS-newline in command):
3224 (Single-quote-BS-newline in command):
3225 (Single-quote-newline-BS-newline in command):
3226 Use printf '%s\n' instead of echo, for portability to hosts
3227 where echo interprets backslashes. This will break on hosts
3228 that lack printf, but for now let's assume all such hosts
3229 are dead (if not, we should get reports of test failures).
3231 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3233 'echo' has some portability problems, when given a first argument
3234 with a leading '-', or when given any argument containing '\'.
3235 Avoid using 'echo' in these cases.
3236 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

3264 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3265 Don't use ECHO_T, since ECHO_N is now reliable.
3266 * lib/autotest/general.m4 (AT_INIT): Likewise.
3267 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3268 rather than using a here-document to put the script into a file.
3269 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3271 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3272 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3273 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3274 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3275 * lib/autotest/general.m4 (AT_SETUP): Likewise.

3277 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

3279 operand, as AS_ECHO requires. Avoid double file name expansion.
3280 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3281 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3282 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3283 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3284 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3285 Double-quote strings that would otherwise contain M4 comments.
3286 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3288 * configure.ac (AC_INIT): Bump to 2.61a.
3291 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3295 * configure.ac (AC_INIT): Bump to 2.61.
3298 * tests/autotest.at (Macro with backslash in a test title):
3299 Comment out for now, as this tests neither fails nor passes
3300 reliably. Problem reported by Ralf Wildenhues.
3302 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>

3317 Import these changes from config via gnulib:
3319 2006-11-15 Ben Elliston <bje@gnu.org>
3321 From Josselin Mouette <joss@debian.org>:

3378 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
3379 benefit of platforms like Solaris+GCC where it is common to have a
3380 non-working g++ installation.

3392 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
3393 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
3394 Imported from a similar patch to gnulib by Bruno Haible.
3396 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3398 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

3415 and Stepan Kasal <kasal@ucw.cz>
3417 Handle special characters in test case titles correctly.
3418 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
3420 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
3421 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
3422 argument. Extend to check titles printed by ./micro-suite and
3423 ./micro-suite -l and the title in micro-suite.log.
3424 (Backquote in a test title,
3425 Single-quote in a test title,
3426 Double-quote in a test title): Don't expect failure anymore.
3427 (Backslash in a test title): Put a non-whitespace character after the
3428 backslash so that Bourne shells might actually see it as an escape
3430 (Brackets in a test title,
3431 Pound in a test title,
3432 Comma in a test title,

3439 * tests/torture.at (#define header templates): M4-quote this title in
3440 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3441 The visible effect was a stray [] in the testsuite output.
3443 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3445 * doc/autoconf.texi (Limitations of Builtins): Do not invoke

3448 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3450 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3451 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3452 5363) simply issues a warning when dividing by zero at compile
3453 time. Problem reported by Elias Pipping.
3455 2006-10-26 Eric Blake <ebb9@byu.net>
3458 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3459 show effect on macros that expand with commas.

3484 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
3486 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3487 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3488 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3489 reported by Nelson H. F. Beebe for Coreutils 6.4.
3491 * tests/tools.at (autoconf --trace: user macros): Remove test
3492 for tracing multiline macros, since m4 1.4.7a uses a different
3493 way to number lines. Problem reported by Ralf Wildenhues.
3495 2006-10-24 Stepan Kasal <kasal@ucw.cz>
3497 * bin/autom4te.in (handle_m4): Do not redirect stdin to
3498 /dev/null since the heuristics for interactive behaviour was

3520 * doc/autoconf.texi (Caching Results): Likewise.
3521 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from

3523 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
3524 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

3571 (Imported from Automake.)
3572 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3573 which incorrectly sets the mode of an existing destination
3574 directory. In some cases the unpatched install-sh could do the
3575 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3576 system. We hope this is rare in practice, but it's clearly worth
3577 fixing. Problem reported by Alex Unleashed in
3578 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3579 Also, don't bother to check for -m bugs unless we're using -m;
3580 suggested by Stepan Kasal.

3629 added to the template can get mangled.
3631 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3633 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
3634 include the default headers, and redefine obstack_chunk_alloc
3635 and obstack_chunk_free. Fixes false failure with glibc.
3637 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
3639 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

3652 the NonStop platform.
3653 * doc/autoconf.texi (Posix Variants): Likewise.
3654 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
3656 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
3657 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
3658 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
3659 Use a better substitute, by inspecting the output of "ls"
3660 rather than just using ":".
3661 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
3662 rather than AS_EXECUTABLE_P, since we needn't worry about
3663 non-regular files here.
3665 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
3666 due to configuration hassles with this. See Tonya Underwood's report
3667 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

3678 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
3679 initialization which is not inherited through the environment
3680 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
3681 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

3686 problems with mkdir -p -m.
3688 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
3690 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
3691 comment about ac_cpp_err; it was incorrect, and anyway
3692 ac_cpp_err is being removed below.
3693 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
3694 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
3695 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
3697 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
3698 with werror_flag and conftest.err and so forth. This is more
3699 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
3700 and anyway the user shouldn't normally want to see this gorp logged.
3701 Problem reported by Ralf Wildenhues.
3702 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
3703 empty, not 'no', since the rest of the code uses 'test -z'.
3705 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
3707 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3708 Use a single call to AC_DO_TOKENS rather than multiple, for
3710 (_AC_LINK_IFELSE): Test that resulting file is executable.
3711 Problem reported by mwoehlke in
3712 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
3714 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
3715 than creating a file to use with test -x; this is much faster.
3717 2006-10-02 Bruno Haible <bruno@clisp.org>
3719 * lib/autom4te.in (Automake-preselections): Add
3720 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
3722 2006-09-27 Stepan Kasal <kasal@ucw.cz>
3724 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
3725 standard error, `experr' should be used, not `expout'.
3727 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
3729 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
3730 fseeko testing program twice; just use the earlier result.
3731 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3732 Set cache var to 'unknown' (not 'no') if leaving the macro unset
3733 still doesn't let the program compile.
3734 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
3737 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
3738 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
3739 include it, without including anything else.
3740 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
3742 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
3744 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3746 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
3747 `error.h', and include it, for a `error_at_line' prototype.
3748 Use a nonempty format string in the link test.
3749 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
3750 for a declaration of wait3.

3755 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
3756 can apply to constants too, and that it checks for macro defns.
3757 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
3758 and simply cast the identifier to void. This handles structure
3759 values. Problem reported by Ralf Wildenhues.

3921 except the first two arguments are reversed.

3935 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
3936 programs should use their Gnulib counterparts.

3939 obsolete macros with uses of non-obsolete macros.

3972 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
3973 didn't work if some values were cached but not others. Test for
3974 broken lex libraries like native ia64-hp-hpux11.22; see
3975 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
3976 work around the problem by preferring an empty LEXLIB to -lfl or
3977 -ll. Let the user set LEXLIB='' to indicate no library needed.

4104 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
4105 -Wundef -Werror". Problem reported by David Fang in
4106 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

4126 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
4128 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
4129 problems with arg script text that doesn't end in newline, and

4166 less skeptical about "volatile", after discussion with
4167 Bruno Haible on bug-gnulib.

4178 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
4179 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
4181 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
4183 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
4184 after -R regardless of host. Patrick Welche reports that this
4185 fixes things on NetBSD 3.99.

4195 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
4196 under AC_C_VOLATILE.
4197 (Volatile Objects): Be a little less skeptical about what
4198 "volatile" means. Derived from thoughts by Ben Pfaff in
4199 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
4201 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4205 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4207 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4208 more globally, since the 2006-06-30 patch didn't suffice. Problem
4209 reported by Keith Marshall. Also, don't bother with builddir2,
4210 since it shouldn't be needed any more.
4212 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
4214 * doc/autoconf.texi (Generic compiler characteristics):
4215 Document AC_COMPUTE_INT. Fix wrong statements on Default
4216 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.

4229 * NEWS: Document previous change.
4231 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4233 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4234 Require that long long int be at least 64 bits wide. C99 requires
4235 this and enough programs depend on it so we should check for it.
4236 Bruno Haible reports in
4237 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4238 that long long int is 32 bits wide with some nonstandard compilers.
4239 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.

4243 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4244 to a nonexistent file, so that we don't have to worry about
4245 a local site configuration that doesn't use /usr/local.
4246 Problem reported by Keith Marshall in
4247 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4249 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4251 * doc/autoconf.texi: Be more consistent about using @acronym with
4252 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4253 quite right (it talked about "OSF/Tru64", even though the
4254 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4255 and it even mentioned "OSF 4"!) and at this point there's little
4256 reason to talk about OSF any more, since it died in 1994.
4257 (Specific Compiler Characteristics): Simplify example of
4258 negative-size array.
4259 (File Descriptors): Reorder to make the text flow better.
4260 Remove joke about "appreciate the various levels"; I didn't get it.
4261 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4262 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4263 (File Descriptors, Limitations of Usual Tools):
4264 Tone down the advice against renaming or removing open files.
4265 (Limitations of Usual Tools): Add a new section, on 'rm'.
4267 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4269 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4270 -lXt in LIBS, idea from Karsten Hopp; this was due since
4273 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4274 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4275 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4276 (which belong to Xt, not X itself). See Debian bug 327655.
4278 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4280 * configure.ac (AC_INIT): Bump to 2.60a.
4283 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4287 * configure.ac, NEWS: Update.

4294 quadrigraph correctly in traces.
4296 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
4299 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
4300 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4302 * doc/autoconf.texi (Changed Directory Variables): New node,
4303 to document the whole `datarootdir' business a bit better.
4305 * tests/torture.at (datarootdir workaround): Extend test.
4306 Prompted by report by Alexandre Julliard.
4308 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4310 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4311 when using default mode of IBM C 6 for AIX. Problem and two-line
4312 fix reported by Larry Jones.
4314 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4316 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4317 about literal '${datarootdir}' if a definition is found in the
4320 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4322 * NEWS: Use "M4" rather than "m4" when appropriate.
4323 Problem reported by Eric Blake.
4324 * doc/autoconf.texi: Likewise.
4325 Use @acronym around BSD, GCC, and GNU when appropriate.
4326 (Why GNU M4): Renamed from "Why GNU m4".
4327 (Redefined M4 Macros): Mention that Posix
4328 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4329 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4332 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4334 * bin/autom4te.in (handle_output): Do not forbid the empty
4336 * tests/tools.at (autoconf: the empty token): New test.
4338 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4340 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4341 calls, so that we do not care whether they are LIFO or FIFO;
4342 in the m4_wrap, do not check which diversion is the topmost
4343 one, just check that the stack is balanced at the end.
4344 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4345 base diversion forever--pop the previous diversion before
4346 opening the new one; consequently, remove the m4_wrap call.
4347 * lib/autotest/general.m4 (AT_INIT): Likewise.
4348 * tests/m4sugar.at: Do not use
4349 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
4351 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4352 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4354 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4355 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4356 Rework example of m4wrap token-pasting trouble so that it doesn't
4357 care whether it's LIFO or FIFO.
4358 Fix some "contrary to"s that are awkward in English.
4360 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4362 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4363 to `yes' instead of `int$1_t' if the type is found, for more
4364 consistent configure output (where $1 is the number of bits).
4365 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4366 Suggested by Bruno Haible.
4368 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4369 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4370 with system headers. Report by Bruno Haible.
4372 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4374 * config/config.guess, config/config.sub: Sync from upstream.
4376 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4377 in order to avoid picking up an older installed frozen m4sh.m4f.
4378 Besides an outdated shell startup, this could have been created
4379 by an earlier M4 version with incompatible frozen file format.
4381 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4383 * README: Recommend m4 1.4.4 instead of 1.4.3..
4384 * doc/autoconf.texi: Likewise.
4385 (Special Chars in Names): Say that $(.FOO) is portable, as
4386 suggested by Stepan Kasal.
4387 (Installation Directory Variables, Build Directories):
4388 (Automatic Remaking, Subdirectories, Fortran Compiler):
4389 (Making testsuite Scripts, Defining Directories):
4390 Quote variable usages better.
4391 (Making testsuite Scripts): Add clean-local rule to makefile
4392 snippet, by Eric Blake.
4393 (Installation Directory Variables): Fix table item font.
4394 Reword slightly to clarify. Generalize advice about
4395 not using special characters to include all file-related
4396 vars, not just VPATH.
4397 (Special Chars in Variables): Warn about special characters in
4399 (Assignments): Clarify default-value example as suggested by
4401 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4402 (Special Shell Variables): Note leading ./ or ../, as suggested
4404 (Limitations of Builtins): Under cd, warn about CDPATH.
4405 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4408 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4410 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4411 `@var', for texi2html.
4412 (Systemology): Some more word wrapping, for DVI output.
4413 (autom4te Invocation): The short option for `--melt' is `-M',
4416 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4418 * doc/autoconf.texi: More formatting and English tweaks,
4419 many suggested by Ralf Wildenhues.
4420 Reword to avoid "@code{...}'s" and the like, since it's ugly
4421 with Emacs info mode. discontents -> woes.
4422 Put a few "will"s back. time stamp -> timestamp.
4423 side-effect -> side effect.
4425 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4427 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4428 Warn about $@ not persisting. Problem reported by Julien Danjou in
4429 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4430 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4431 Mention other special chars, too.
4433 2006-06-14 Eric Blake <ebb9@byu.net>
4435 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4437 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4439 * doc/autoconf.texi: Some systematic minor improvements, as
4440 follows. Use "makefile" when talking about makefiles
4441 generally (which might be named "makefile" or "Makefile" or even
4442 "foo.mk"), "Makefile" when talking about a specific makefile
4443 called "Makefile". This unclutters the text from weird quotes
4444 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4445 values" rather than "@var{foo}s" and similar constructs containing
4446 "}s". Use "Make rules" rather than "Makefile rules". Minor
4447 English-language improvements. Change the prefix "sub-" to "sub"
4449 Put blank lines around examples more consistently.
4450 Avoid "rather" and "very" as intensifiers.
4451 Avoid "will" as an auxiliary.
4452 (Limitations of Make): Split this node into....
4453 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4454 (Leading _ in Macro Names, Backslash-Newline-Newline):
4455 (Backslash-Newline Comments, Long Lines in Makefiles):
4456 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4457 (obj/ and Make, make -k Status, VPATH and Make):
4458 (VPATH and Double-colon, $< in Explicit Rules):
4459 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4460 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4461 New nodes, resulting from splitup of Limitations of Make.
4462 All cross-references changed. Raise the top node from
4463 a section to a chapter, and all subnodes accordingly.
4464 Redo the introductory wording to match the new organization.
4465 (Installation Directory Variables): Use an example that is
4466 closer to what Autoconf actually does. Mention that VPATH's
4467 value should not contain metacharacters or white space.
4468 (Fortran Compiler): Fix a VPATH bug in an example.
4469 (Leading _ in Macro Names): Mention that this problem is no longer
4470 of practical concern.
4471 (VPATH and Make): Reword the advice to make it clearer
4472 that Autoconf and Automake support VPATH in non-GNU make, but
4473 many packages have bugs in this area.
4474 ($< in Explicit Rules): Refer to Build Directories rather
4475 than using a (non-VPATH-safe) example.
4476 (Automatic Rule Rewriting): Mention the sort of disaster that
4477 can ensue with Solaris-style rule rewriting with VPATH.
4479 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4481 * doc/install.texi (Compilers and Options): Weaken the
4482 suggestion to use GNU make for VPATH builds.
4484 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4485 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4487 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4488 in regular expression.
4490 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4492 * doc/autoconf.texi (Installation Directory Variables):
4493 Drop extra @samp from `@table @samp' item.
4494 (Limitations of Usual Tools): Comment fix.
4495 Do not nest @samp just to point to other table items.
4496 (Writing testsuite.at) <AT_CHECK>: The second argument to
4497 `@dvar' is already @samp'ed.
4498 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4499 do not use @var in the second argument.
4501 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4503 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4504 $as_shell.exe too. Problem reported by Andreas Buening in
4505 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4507 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4509 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4510 `unused variable' compiler warning, for `-Wall -Werror'.
4511 Reported by Jaap Haitsma in
4512 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4514 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4516 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4517 case the compiler dumps core. Problem reported for
4518 OpenServer 5.0.7 by Tim Rice in
4519 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
4520 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4523 2006-06-06 Tim Rice <tim@multitalents.net>.
4525 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4526 "ERROR" only shows up in "make check" output if there is an
4529 2006-06-06 Eric Blake <ebb9@byu.net>
4531 * tests/tools.at (automatically allowed tokens): Fix typo.
4533 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4535 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
4537 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
4538 typically overflows on x86 CPUs, even though the C standard
4541 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4543 * configure.ac (AC_INIT): Bump to 2.59e.
4546 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4550 * config/texinfo.tex: Sync from upstream.
4552 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4553 seen, invoke libtoolize with `--ltdl' argument.
4554 * lib/autom4te.in (Autoreconf-preselections): Adjust.
4556 Suggested by Eric Blake.
4558 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4560 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
4561 reported by Ralf Wildenhues.
4562 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
4564 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4568 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4570 * doc/autoconf.texi: Modernize some of the references to Solaris.
4572 2006-06-05 Stepan Kasal <kasal@ucw.cz>
4574 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
4575 message issued by AC_REQUIRE.
4576 * tests/m4sugar.at: Check m4_require's error message.
4577 * tests/base.at: Check AC_REQUIRE's error message.
4578 * tests/local.at (AT_CHECK_M4): New macro, almost identical
4580 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
4582 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
4583 `expout' as the last parameter.
4584 * tests/tools.at: Adapt to the above change.
4586 2006-06-04 Stepan Kasal <kasal@ucw.cz>
4588 * doc/autoconf.texi (Limitations of Usual Tools): Correct
4589 information about race-free implementations of mkdir.
4591 2006-06-04 Eric Blake <ebb9@byu.net>
4593 * bin/autoreconf.in (help): Document M4 environment variable.
4594 * bin/autoconf.as (Usage): Likewise.
4595 * bin/autom4te.in (help): Likewise.
4596 * doc/autoconf.texi (autom4te Invocation): Likewise.
4598 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
4600 * NEWS: GNU make now recommended for VPATH builds.
4601 Mention that some macros are now documented to be obsolescent.
4602 * doc/autoconf.texi:
4603 Prefer "current" to "modern" to describe
4604 currently-used (albeit perhaps old-fashioned) hosts.
4605 Mention which ancient features no longer need to be worried about.
4606 setgid -> set-group-ID
4607 setuid -> set-user-ID (these are the Posix terms)
4608 Fix some misuses of "only".
4609 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
4610 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
4611 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
4612 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

4617 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
4618 Mention that these macros are obsolescent.
4619 (Installation Directory Variables): shall -> should
4620 (File Descriptors): Mention that 0, 1, 2 might get reopened.
4621 Mention that it's now safe to use 3 and 4.
4622 (Limitations of Usual Tools): cp -r is now specified by Posix.
4623 Omit longwinded and obsolescent discussion of cp -f.
4624 Modernize discussion of expr, ls.
4625 (Limitations of Make): Modernize discussion of VPATH builds.
4626 Mention $? as a workaround in some cases.
4627 * doc/install.texi (Basic Installation):
4628 Mention "./configure; make; make install" first. Be more
4629 specific about why this file is generic. Remove unnecessary
4630 parens. Remove misleading "only". Remove obsolete advice
4631 about csh. Don't say "configure" takes awhile; say it
4632 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
4633 and CC=c99 rather than CC=c89, as these are blessed by current
4634 Posix. Recommend GNU make if doing a VPATH build.
4636 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
4638 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
4639 examples involving shell prompts.
4641 2006-06-02 Stepan Kasal <kasal@ucw.cz>
4642 and Paul Eggert <eggert@cs.ucla.edu>
4644 * doc/autoconf.texi (Here-Documents): Add details about the
4645 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
4646 use "here-documents" instead of "here documents".
4648 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4650 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
4652 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
4654 * doc/autoconf.texi (File System Conventions): Warn about ":"
4655 anywhere in directory names.
4657 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
4659 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
4660 about quoting the case statement, just in case.
4661 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
4662 was fixed in ksh93g; reported by Ralf Wildenhues.
4664 2006-05-31 Stepan Kasal <kasal@ucw.cz>
4666 * doc/autoconf.texi (System Services): Do not document
4667 overriding EXEEXT via ac_cv_exeext=ext.
4668 (Particular Programs) <AC_PROG_MKDIR_P>:
4669 Document that ${MKDIR_P} understands --.

4673 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4675 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
4676 argument with leading hyphen. Problem reported by Paul Eggert.
4678 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4680 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
4681 about quoting ac_try: quote all of it, if any of it seems suspicious.
4682 This means we don't have to worry about ${ or sed any more.
4683 Also, double-quote the case statement, to work around misuses via
4684 underquoting as reported by Ralf Wildenhues in
4685 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
4686 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
4687 undocumented and dangerous macro.
4688 Problem reported by Ralf Wildenhues in
4689 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
4691 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4693 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
4694 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.

4699 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
4700 since evidently some packages rely on the old, broken behavior.
4701 Problem reported by Ralf Wildenhues in
4702 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
4703 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
4704 pre-2006-05-26 definitions, but leave in the comments that
4705 these macros are dangerous and should not be used.
4706 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
4707 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
4708 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
4709 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
4710 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
4712 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4714 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
4715 the use of 'tr', since this is our only use of 'tr'.
4717 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4718 and Paul Eggert <eggert@cs.ucla.edu>
4720 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
4721 Don't assume 'grep' works on long lines, since AIX grep doesn't.
4723 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4725 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
4726 the output file in the `${datarootdir}' test.
4728 2005-05-28 Stepan Kasal <kasal@ucw.cz>
4729 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4731 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
4732 mention of `datarootdir' in the input file(s), but literal
4733 `${datarootdir}' in the output file, and we haven't warned yet,
4734 then warn as well: the user may have (erroneously) used
4735 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
4736 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
4737 * tests/torture.at (datarootdir workaround): Extend this test.
4740 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4741 and Paul Eggert <eggert@cs.ucla.edu>
4743 * doc/autoconf.texi (autoheader Invocation): The first argument to
4744 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
4745 alternatives and clear up the language a bit.
4747 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
4749 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
4750 ac_config_guess, ac_config_sub, ac_configure.
4751 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4752 Fix typo that prevented an unnecessary space from being removed.
4753 Problems reported by Ralf Wildenhues in:
4754 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
4756 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4758 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
4759 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
4760 Don't use the term "thread-safe" to talk about mkdir race
4761 conditions, since the problem is more a process than a thread
4762 issue. Problem reported by Stepan Kasal in:
4763 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
4764 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
4765 the test for 'install' more closely. Look at MKDIR_P first.
4766 Look in the PATH, and at /opt/sfw/bin.
4767 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
4768 Don't bother to try mkdir -p, since we already check mkdir --version;
4769 just look at the version number. (There's no easy way to check
4770 for race-free implementations.)
4771 * tests/tools.at (autoconf: subdirectories): Adjust to above
4772 changes, since MKDIR_P now might end in "/mkdir -p".
4774 * doc/autoconf.texi (autoheader Invocation): Mention that the
4775 first arg of AC_DEFINE_UNQUOTED must be a literal.
4776 Problem reported by Ben Pfaff in
4777 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
4779 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
4780 * doc/autoconf.texi (Special Chars in Variables): New section.
4781 (Preset Output Variables): Warn about special chars in CPPFLAGS.
4782 (Installation Directory Variables): Quote $(datadir) better.
4783 (Limitations of Builtins): Describe some of eval's trickiness.
4785 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
4786 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
4787 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
4788 in front of every arg, not just trailing args. Quote apostrophes.
4789 (_AC_EVAL_ECHO): New macro.
4790 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
4791 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
4793 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
4794 exposed by quoting of eval argument. Put the command on line line
4796 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
4797 (_AC_PATH_X, AC_PATH_X): Quote more safely.
4798 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
4799 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
4800 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
4801 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
4802 Use eval more safely.
4803 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
4804 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
4806 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
4807 lines, exposed by quoting of eval argument.
4809 2006-05-26 Stepan Kasal <kasal@ucw.cz>
4810 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4812 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
4813 initialization of `ac_cv_exeext', do not override it if it was
4814 already set, unless it was set to `no', for compatibility with
4815 Autoconf-2.13, and comment this.
4816 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
4817 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
4818 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
4819 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
4820 Document that this test may be overridden by setting
4823 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4825 Revert these two patches:
4827 2006-04-06 Eric Blake <ebb9@byu.net>
4828 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4829 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4832 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4833 Clean up _AC_COMPILER_EXEEXT* macros.
4834 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4835 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4836 ac_file to the name of the default output file and call
4837 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4838 initial `rm' of the candidate files...
4839 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4840 the same list in subsequent `rm' calls, and for the temporary
4841 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4842 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4843 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4844 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4845 no longer needed) by libtool. Make it a cache check.
4846 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4847 copied here by mistake.
4848 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4849 _AC_COMPILER_EXEEXT.
4850 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
4851 _AC_COMPILER_OBJEXT directly.
4852 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4854 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4856 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
4857 Fix description of how the buggy `sed' works.
4859 2006-05-25 Noah Misch <noah@cs.caltech.edu>
4863 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
4864 ENOLCK. Only mention `make -j' when applicable. Only raise
4865 fatal errors when `make -j' is involved. Improve error message.
4867 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4869 * doc/autoconf.texi (Here-Documents): We now know more about
4870 the variable expansion in here documents bug.
4871 Thanks to Tim Rice and Stepan Kasal.
4873 * doc/autoconf.texi (Making testsuite Scripts): Add an example
4874 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
4876 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4878 * tests/autotest.at (Multiline command from M4 expansion):
4879 No failure to be expected if the shell quotes newlines in
4880 commands in the `set -x' output. Report by Tim Rice.
4883 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4885 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
4886 expansion in the here-documents used by config.status, as that
4887 runs afoul of the Korn shell version M-12/28/93d bug described in
4888 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
4889 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
4890 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
4892 2006-05-23 Jim Meyering <jim@meyering.net>
4894 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
4895 Fix typo introduced with 2006-04-02 change. It reversed the sense
4898 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4900 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
4901 ac_dB slightly, to save bytes in the script.
4902 Max out at 50 lines, rather than 96; this is more likely
4903 (though not guaranteed) to avoid obscure 'sed' failures.
4905 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4907 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
4908 `tr -d -' as bad option argument. Work around this by deleting
4909 an unrelated character.
4910 Report by Tim Rice <tim@multitalents.net>.
4912 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
4913 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4914 Stepan Kasal <kasal@ucw.cz>
4916 * doc/autoconf.texi (Particular Programs): Do not promise that
4917 we always prefer the GNU version of the program, and that we
4918 search according to PATH; both rules can have exceptions.
4919 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
4920 AC_PROG_SED. Move descriptions of limitations
4921 to the Limitations of Usual Tools section.
4922 (Limitations of Usual Tools) <sed>: Mention script length
4923 limitations with Solaris /usr/ucb/sed.
4924 <grep>: Fix wording for empty alternative. Mention that -c and
4925 -l should not be combined, and that -E and -F should not be
4928 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4929 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4931 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
4932 limits in Solaris 8 /usr/ucb/sed by testing a long script.
4934 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4936 * doc/autoconf.texi (Defining Symbols): Literal parameter of
4937 AC_DEFINE is now passed to m4_pattern_allow.
4938 * NEWS: Mention that; likewise for AC_SUBST.
4939 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
4940 the parameter to m4_pattern_allow.
4941 * tests/tools.at: Add a check for that.
4943 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4945 * lib/autoconf/status.m4: Fix typos.
4947 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4949 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
4950 only the files that this macro generates.
4952 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4954 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
4955 the HP-UX sed limitation of 99 commands, labels do not count.
4956 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
4958 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
4960 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4962 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4963 Import the following fix from coreutils:
4965 2006-01-13 Jim Meyering <jim@meyering.net>
4967 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
4968 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
4969 not double-quote uses of that variable, to accommodate the rare
4970 case in which getmntent is available in none of the libraries
4971 checked. This happens at least on FreeBSD 5.0.
4973 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
4975 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
4976 ac_config_guess, ac_config_sub, and ac_configure, since evidently
4977 some other programs unwisely rely on these undocumented vars.
4978 But put in warning comments about them.
4979 Problem reported by Ralf Wildenhues in
4980 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
4981 * NEWS: Document that these variables are intended to go away.
4983 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4985 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
4986 and set the language to C++ (analogous to the equivalent Fortran
4989 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
4990 * doc/autoconf.texi (C++ Compiler): Document it.
4991 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
4994 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
4996 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
4997 that caused config.status to generate 100-command sed scripts; the
4998 portable limit is 99.
5000 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5002 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5003 variable `ac_d' instead of `d' to avoid infringing namespace.
5004 Report by Ralf Menzel.
5006 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5008 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5009 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5010 * tests/tools.at (autoconf: subdirectories): New test, taken from
5011 the corresponding problem report by Ralf Wildenhues in:
5012 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5014 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5015 Quote some uses of shell variables if they might suffer unexpected
5016 globbing. This doesn't fix all instances of quoting problems that
5017 I found, just the easy ones that look safe.
5018 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5019 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5020 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5021 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5022 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5023 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5024 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5026 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5027 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5029 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5031 * bin/autoreconf.in ($help): Reword according to the manual.
5032 Suggested by Olly Betts.
5034 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5035 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5037 * bin/autoreconf.in: Pass the directory argument to
5038 `require_configure_ac'. Fix comment.
5039 * tests/torture.at (Configuring subdirectories): Expose this.
5040 Reported by Olly Betts.
5042 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5044 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5045 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5046 Automake as follows:
5048 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5049 `$configure_in' instead of `configure.in', to preserve
5050 directory component.
5052 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5054 * config/config.guess, config/config.sub, config/texinfo.tex,
5055 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5057 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5059 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5060 test for C99 conformance; (bool) 0.5 is an integer constant
5061 expression, but (bool) -0.5 is not. Problem reported by Fedor
5062 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5064 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5066 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5067 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5068 Warn about obsolete install-sh files. Remove stray sentence
5069 fragment and fix cross reference.
5070 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5071 install -d; this undoes the 2006-05-10 change.
5072 (MKDIR_P): Mark with AN_MAKEVAR.
5073 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5074 that we don't require $INSTALL to be thread-safe. Move comments
5075 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5076 of AC_PROG_INSTALL. Output a message saying that we're checking
5077 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5078 MKDIR_P instead of AC_SUBST.
5079 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5080 Special magic for MKDIR_P, too.
5081 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5083 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5085 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5087 Sync from Automake, as follows:
5089 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5090 * config/install-sh: Initialize IFS, so field splitting isn't
5092 * config/mkinstalldirs: Likewise.
5093 * config/missing: Remove superfluous quotes. Replace all uses of
5094 `[' by `test', for consistency, and for..
5095 * config/missing (sed_minuso, sed_output): New variables.
5096 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5097 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5098 Fixes `missing' to detect `--output' for help2man. Fixes
5099 PR automake/483. Report by Dennis J. Linse.
5100 (autom4te): Document in `missing --help'.
5102 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5104 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5105 * config/install-sh: Don't use 'path' to talk about file names,
5106 as per GNU coding standards. Close a race condition reported by Ralf
5107 Wildenhues and Stepan Kasal. There is still a race condition
5108 on hosts that predate Posix 1003.1-1992, but we can't help this.
5109 Don't mishandle weird characters like space on pre-Posix hosts.
5110 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5111 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5112 AC_PROG_MKDIR_P from AS_MKDIR_P.
5113 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5114 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5115 earlier editions are not (including Automake 1.8.3).
5116 Do not suggest mkinstalldirs for thread-safety.
5117 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5118 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5119 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5120 presence of special characters and race conditions.
5121 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5122 in Autoconf's name space.
5124 2006-05-10 Bruno Haible <bruno@clisp.org>
5125 and Paul Eggert <eggert@cs.ucla.edu>
5127 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5128 from Automake with minor changes.

5131 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5133 * config/install-sh: Update to Automake CVS version, as follows:
5134 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5135 * lib/install-sh: Simplify the expr implementation of dirname.
5136 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5137 * lib/install-sh: Handle --, and diagnose unknown options.
5139 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5141 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5142 `./autom4te' to create `./testsuite', since the `all' target
5143 will ensure its presence, but `installcheck' should not create
5144 the uninstalled wrappers.
5146 * tests/torture.at (Unusual Automake input files): Skip if we
5147 detect automake < 1.8.
5149 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5151 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5152 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5153 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5156 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5158 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5159 munge (multiple) white space and other oddities.
5160 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5161 single quotes in variable assignment.
5162 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5163 and similar failures by adding multiple spaces, tabs, and other
5165 Report and different test suggested by Francesco Romani
5166 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5168 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5169 single quotes, we only need to search for single quotes; this
5170 both simplifies the search pattern, and makes us less
5171 susceptible to `echo' variations for arguments not containing
5173 (_AC_ARG_VAR_VALIDATE): Likewise.
5175 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5177 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5178 `$*' and IFS concatenation issue with traditional shells and
5179 bash-2.04. Report by Seanster@Seanster.com.
5181 2006-05-03 Bruno Haible <bruno@clisp.org>
5183 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5184 precisely which Mac OS X versions have the od problem.
5186 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5188 * doc/autoconf.texi: Use @option systematically.
5190 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5191 and Bruno Haible <bruno@clisp.org>
5193 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5195 (Integer Overflow): Mention the special case of integer division
5198 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5200 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5201 traditional shells like the Solaris one that do not use the
5202 first IFS character for assembling `$*'.
5203 Prompted by a related report from autoconf_bug@nro.ca.
5205 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5206 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5208 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5209 Mention more problems with the -e option.
5211 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5214 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5216 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5217 in URLs to improve DVI formatted output (requires texinfo 4.6).
5218 (System Services, Systemology, Shellology): Likewise.
5219 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5222 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5224 (Runtime): Fix macro argument names to match description:
5225 `action-if-found' -> `action-if-true' and similarly.
5226 (Obsolete Macros): Likewise.
5227 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5228 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5229 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5231 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5233 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5236 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

5263 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5264 since as_me isn't set yet.
5266 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5268 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5269 a few minor bugs in this area.
5271 * doc/autoconf.texi (Programming in M4sh): Comment out the
5272 documentation of AS_BASENAME, for now.

5299 * lib/autoconf/headers.m4: Likewise.
5301 * doc/autoconf.texi (Run Time): Document the exit status situation
5302 with more accuracy and detail.
5304 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5306 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5307 Archive is not officially `GNU' any more. Update URL.
5308 (Defining Directories): Likewise
5309 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5311 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5313 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5314 newline from the `trap' code to finish `config.log'; the NetBSD
5315 /bin/sh resets the exit status after an empty command, as
5316 documented in doc/autoconf.texi.
5317 Reported by Dalibor Topic <robilad@kaffe.org>.
5319 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5321 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5322 Suggested by Bruno Haible.
5324 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5326 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5327 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5328 Instead, just list the shells that we know work.
5329 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5330 changed. Be more cautious about the _cv_ variable.
5331 * tests/tools.at (Syntax of the shell scripts): Check the
5332 _cv_ variable once, at first, to avoid an internal autoconf error
5333 when sh -n does not work.
5335 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5337 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5339 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5341 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5342 use ">&-" since we're only 99.999% sure that this is portable,
5343 and since the MinGW bug is fixed in a different way.
5344 * lib/autotest/general.m4 (AT_INIT): Likewise.
5346 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5348 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5349 before opening config.log, to avoid hitting a bug on MinGW.
5351 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5353 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5354 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5355 This works around a MinGW bug reported by Eric Paire.
5356 Make sure that all writes to the log file append to it,
5357 rather than possibly losing data.
5358 * lib/autotest/general.m4 (AT_INIT): Likewise.
5360 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5362 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5365 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5369 * configure.ac (AC_INIT): Bump to 2.59d.
5371 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5375 * Makefile.maint (news-date-check): Do not require a leading `*'
5376 before the release date in NEWS.
5378 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5379 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5381 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5382 the instantiated file do not contain the string 'datarootdir'
5383 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5384 @mandir@, replace the reference '${datarootdir}' by the value.
5385 * tests/torture.at (datarootdir workaround): New test.
5386 * NEWS: Advertise this temporary fixup.
5387 Based on a patch by Bruno Haible, reported and analyzed by
5388 Paul Eggert and Noah Misch.
5390 2006-04-12 Eric Blake <ebb9@byu.net>
5392 * tests/autotest.at (Debugging a failed test): Fix comment.
5394 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5396 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5397 all the changes since 2006-04-07.
5399 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5401 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5402 succeeded, but `ln -s file dir' failed, take care to remove the
5403 leftover target before the next test, to prevent its spurious
5404 failure; also make sure `ln file dir' works before selecting it.
5405 Thanks to Keith Marshall for pointing this out.
5408 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5409 assignments in `at_debug_args', so that we put them correctly
5410 in the `run' script.
5411 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5412 Reported by Eric Blake.
5414 2006-04-11 Eric Blake <ebb9@byu.net>
5416 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5417 top-level tests after micro-suite has been run. Used in...
5418 (Debugging a successful test, Debugging script and environment),
5419 (Debugging a failed test): ...these new tests. The first of these
5421 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5422 macro, split out from...
5423 (AT_INIT): ...here, so that using -d also generates a run script.
5424 Document that -d inhibits top-level logging.
5425 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5426 inhibits top-level logging; debug scripts are created.
5428 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5430 * tests/autotest.at (Empty test, Empty check): New test to check it.
5432 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5435 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5437 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5438 the files if a problem appears. Make the empty *.at files
5439 read-only, too. Proposed by Ralf Wildenhues.
5441 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5443 * config/Makefile.am: Add comment to force updated Makefile.in.
5445 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5446 space only patch to this file, this patch causes the Makefile.in
5447 files that include freeze.mk to be updated, and thus have a
5448 newer time stamp again, which in turn makes a pristine CVS
5449 checkout have correct time stamps.
5451 * Makefile.maint (cvs-sv): New macro, to be used..
5452 (config.guess-url_prefix, config.sub-url_prefix)
5453 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5454 point to CVS text checkout of Gnulib files.
5455 (copyright-check): Bump current year.
5456 (announcement): Do not hard-wire `./announce-gen'.
5457 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5459 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5461 (wget_files): Update config.guess, config.sub, texinfo.tex by
5462 `wget-update', now that their URLs work again.
5464 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5466 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5467 Problem noted by Paul D. Smith.
5469 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5471 * doc/autoconf.texi: Remove unused words from word list.
5472 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5473 .x-sc_trailing_space: New files.
5475 * doc/standards.texi: Sync from gnulib.
5477 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5478 `LIBOBJDIR' as experimental.
5480 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5481 with a target directory; it's internally implemented as `cp'
5482 anyway, but since Autoconf advertises the possibility to use
5483 a target directory when LN_S is `ln -s', we need to find out.
5484 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5485 analyzed by Keith Marshall <keith.marshall@total.com>.
5489 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5491 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5492 confdefs.h as-is. In general, if it has backslash-newline or the
5493 like, then it doesn't work either to sort or to remove empty
5496 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5498 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5500 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5502 * lib/autom4te.in (Automake-preselections): Preselect
5505 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5507 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5508 apostrophe within a single-quoted string, as this is the usual
5509 tradition and is easier to read than '"'"'. Don't rely on the
5510 shell treating "$/" like '$/'. Use a more-consistent indenting
5513 2006-04-09 Eric Blake <ebb9@byu.net>
5515 * tests/autotest.at (Backquote command substitution),
5516 (Multiline backquote command substitution): Remove mistaken
5517 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5519 (Parenthetical command substitution, Multiline parenthetical
5520 command substitution): here.
5522 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5524 Import macros from gnulib (often changing their name).

5555 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
5556 (C Compiler): Move AC_C_LONG_DOUBLE to ...
5557 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
5558 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
5559 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
5560 (Coding Style). Don't mention m4_expand_once.

5582 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
5584 2006-04-08 Stepan Kasal <kasal@ucw.cz>
5586 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
5587 of the warning introduced by the 2001-08-28 change.
5589 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
5590 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5592 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
5593 variables shall be overriden by the cache.

5597 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5599 Revert the patch from 2006-04-01 and only improve
5600 _AS_DETECT_BETTER_SHELL:
5602 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
5603 skip nonexistent directories.
5604 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
5605 only shell candidates which exist.
5606 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
5607 * lib/autotest/general.m4 (AT_INIT): No need to give three
5608 parameters to _AS_PATH_WALK.
5610 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
5611 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5613 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
5614 distinguish m4sugar macros.
5615 * tests/tools.at (autoupdating with aclocal and m4_include):
5616 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
5617 test case by Noah Misch <noah@cs.caltech.edu>.
5619 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5621 Revert my change from 2006-03-17, in other words:
5622 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
5624 (AS_SHELL_SANITIZE): Remove DUALCASE=1.

5630 * doc/autoconf.texi (Programming in M4sh): Document that
5631 AS_MKDIR_P exits the script on failure.
5632 * lib/autotest/general.m4: Remove redundant AS_ERROR.
5634 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5636 * config/elisp-comp, config/install-sh, config/mdate-sh,

5653 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5655 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
5656 whether `set' quotes correctly: redirect stderr of the tested
5657 `set', and use a subshell, for Ultrix; use `sed' instead of
5658 `grep' for zsh `set' which may write binary output; match only
5659 at the beginning of a line, to avoid false positives.
5660 In order to avoid false positives by unrelated variables with
5661 multiline content, put the dump algorithm in a subshell and
5662 unset all variables containing newlines (except some which are
5663 special to the shell). Warn about cache variables that are

5668 * config/config.guess, config/config.sub, config/texinfo.tex:
5671 * tests/mktests.sh: Reword comments.

5677 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
5678 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
5679 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
5680 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
5682 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
5683 shell issue with double-quoted command substitutions of native
5685 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
5688 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

5703 2006-04-06 Stepan Kasal <kasal@ucw.cz>
5705 * tests/Makefile.am (maintainer-check-posix):
5706 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
5708 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
5709 ac_config_<foo>s again, sometimes normalized, sometimes not.
5710 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
5711 (AC_CONFIG_COMMANDS): Do not do so here.
5712 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
5713 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
5714 2005-07-25 rewrite. Noticed by Noah Misch.
5716 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
5717 _AC_PRESERVE_HELP_ORDER, ...
5718 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
5720 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
5721 inside m4_expand_once; it is redundant.

5724 for --help from Cygnus `configure.'
5726 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

5739 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
5740 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
5741 * doc/autoconf.texi (Help Formatting): New node.
5742 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
5744 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5783 (exclude_list): Exclude empty macros.
5784 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

5789 Switch from grep to awk syntax.
5790 (ac_exclude_script): Renamed from ac_exclude_egrep.

5870 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5871 initial `rm' of the candidate files...

5873 the same list in subsequent `rm' calls, and for the temporary
5874 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,

5878 no longer needed) by libtool. Make it a cache check.

5880 copied here by mistake.

5955 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5957 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
5958 switch all of them on and of when necessary. Fixes the bug when

6217 newline for portability.
6218 * tests/torture.at (Torturing config.status): Also test 100

6710 suggested by Ben Elliston. Handle weird characters correctly.
6712 2005-09-06 Stepan Kasal <kasal@ucw.cz>
6714 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
6715 calls, so that the final expansion of this macro is shorter.
6716 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
6717 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
6718 the cleanup there. Use AS_VAR_* macros, to be more general.
6719 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
6721 * lib/autoconf/general.m4: Use AS_IF where appropriate.
6723 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
6725 2005-09-01 Stepan Kasal <kasal@ucw.cz>

6741 2005-08-26 Stepan Kasal <kasal@ucw.cz>
6743 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
6744 in the example. Reported by Bruno Haible.
6745 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
6746 "if $undefined_var;" succeeds with my shell.
6748 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
6749 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
6750 but change the m4_divert_text to m4_divert_once.
6752 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
6754 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
6755 Work around bug in Solaris /usr/xpg4/bin/awk.
6756 The bug is present in at least Solaris 8 through 10.
6758 2005-08-24 Stepan Kasal <kasal@ucw.cz>
6760 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
6761 some evil values and relying on the fact that $* concatenates the
6762 parameters by the first character from IFS.
6764 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6765 Stepan Kasal <kasal@ucw.cz>

6768 first header appears, define AH_HEADER.
6769 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
6770 Update limitations about when to call AC_CONFIG_HEADERS.
6771 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
6772 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
6773 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
6774 ``Configuration Actions''; fix their index entries.
6776 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
6777 options correctly. Process N-M as M-N if M is smaller than N.
6778 Process ranges correctly so that N-N will run only N.
6779 Sort and uniquify the tests that will be run. If there is more
6780 than one test, reinsert the banners for the tests.
6781 * tests/autotest.at (Keywords): Unmark XFAIL.
6783 2005-08-23 Stepan Kasal <kasal@ucw.cz>
6785 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
6786 before passing the macro name to AH_TEMPLATE.
6788 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
6789 now opens log after option processing; in particular, --version
6790 and --help do not touch config.log.

6802 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
6803 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
6806 * doc/autoconf.texi (Defining Symbols, Changed Results):
6807 Prepend to LIBS, not append, in examples.
6809 2005-08-16 Stepan Kasal <kasal@ucw.cz>
6811 When building in place, set srcdir="."; suggested by Tim Van Holder.
6813 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
6814 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
6815 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
6816 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
6817 does not mean "no --srcdir option".
6819 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6830 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
6831 add "2>&1"; gzip 1.2.4 prints help on stderr.
6833 2005-07-27 Stepan Kasal <kasal@ucw.cz>
6835 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
6836 was pushdef'ed twice while popped only once. Push it only once.
6837 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
6839 2005-07-26 Stepan Kasal <kasal@ucw.cz>
6841 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

6848 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
6849 "<tab>" in comment, so that the point is understandable.
6851 2005-07-25 Stepan Kasal <kasal@ucw.cz>
6853 Rewrite substantial part of lib/autoconf/status.m4.
6854 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
6855 and CONFIG_COMMANDS are not processed in four separate loops.
6856 Instead, there is one main loop. This alows that the common code
6857 is expanded only once, thus config.status (and configure) is smaller.
6859 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
6860 the AC_LIST_FILES and cousins macros are no longer used.
6862 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
6863 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
6864 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
6865 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
6866 contain the initialization, nor the for loop, nor the associated
6867 commands; all these go to ...
6868 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
6869 _AC_OUTPUT_CONFIG_STATUS.
6870 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
6871 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
6872 (_AC_OUTPUT_FILE): The creation of the sed script ...
6873 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
6874 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
6875 _AC_OUTPUT_MAIN_LOOP.
6876 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
6877 _AC_CONFIG_COMMANDS): Use ...
6878 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
6879 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
6880 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
6881 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
6882 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
6883 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
6885 (_AC_CONFIG_UNIQUE): Update.
6886 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
6887 Replaced by this ...
6888 (_AC_LIST_TAGS): ... new common macro.
6889 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
6890 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
6891 (_AC_LIST_TAG_COMMANDS): ... new common macro.
6892 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
6893 this didn't belong to the `config commands' section.
6894 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
6895 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
6896 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
6897 to the `config commands' section either.
6898 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
6899 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
6901 ... and many changes to the comments nearby.
6903 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
6904 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
6905 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6906 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
6907 (#define header templates): The comment at the top of the generated
6908 header now includes the name(s) of the source file(s).
6910 Several unrelated small changes:
6912 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
6913 parameter to AC_DIAGNOSE.
6914 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
6915 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
6916 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
6917 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
6919 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
6920 in AC_OUTPUT doesn't double-quote it either.
6921 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
6924 2005-07-10 Stepan Kasal <kasal@ucw.cz>
6926 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
6927 versions of Portland Group compiler produce single- and double-quoted
6928 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
6929 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
6931 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
6933 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
6934 This is a corrected version of yesterday's patch.
6936 2005-07-07 Stepan Kasal <kasal@ucw.cz>
6938 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full

6942 ac_cv_build_alias to ac_build_alias.
6943 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
6945 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
6946 change eliminates it. Problem reported by Alexandre Duret-Lutz.
6947 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
6948 (AC_ARG_VAR): ... here.
6949 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
6952 Keep a list of all precious variables and process them with one simple
6953 for loop, instead of expanding all commands, or, OTOH, complicated
6954 processing of output of "set".
6955 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
6956 variable names in new macro...
6957 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
6958 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
6959 a loop to assign all ac_env_* and ac_cv_env_* variables.
6960 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
6962 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
6963 its value to shell variable ac_precious_vars and call
6964 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
6965 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
6966 _AC_ARG_VAR_VALIDATE.
6968 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

6999 at_top_builddir, for compatibility with older autotest.
7000 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
7001 is not set, use at_top_builddir, for compatibility with older
7002 versions of autoconf.
7004 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7006 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
7007 Problem reported by Patrick Welche.
7009 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
7011 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7012 sed substitution command, so that we allow | in program prefixes
7013 and program suffixes. (& is a problem anyway; we're not fixing
7015 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
7016 configure_input, top_builddir, srcdir, etc.
7017 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7018 PATH_SEPARATOR in AUTOTEST_PATH.
7020 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
7022 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
7023 for loop over config.site files using `set', to allow

7028 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
7029 directories with weird names. Apparently some people like living
7030 on the edge. However, improve the test that "pwd" actually does
7031 report a name for the working directory.

7051 document to output the default config_* lists to config.status.
7052 Don't recognize option --file, if the functionality is not there.
7053 Likewise for --header; moreover, recognize --he and --h as shortcuts
7054 for --help in that case.
7056 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7057 matches the order of execution. No code changed.

7079 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7080 (AC_SUBST): Call it.
7081 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7082 the directory specific variables; but don't call it for configure_input.
7084 2005-06-28 Derek Price <derek@ximbiot.com>
7086 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7089 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7091 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

7157 * doc/autoconf.texi:
7158 Don't mention Solaris versions so much, if a
7159 problem is common to all extant versions of Solaris. Say "SunOS
7160 4" instead of "SunOS" for SunOS 4.
7161 (awk): Mention more of the limitations of traditional Awk.
7162 (cat): Don't talk about cat -v.
7164 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

7167 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
7168 but the implementation is entirely different and is designed
7169 to be compatible with glibc strverscmp.
7170 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
7172 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
7173 on Mac OS X 10.4 reported by Peter O'Gorman in:
7174 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
7175 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
7176 Use shell builtins rather than 'expr', to work around expr bug.
7178 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
7180 * doc/autoconf.texi: "filesystem" -> "file system".
7181 "behaviour" -> "behavior".
7182 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
7183 * lib/autoconf/general.m4: Omit blank after ":" sed command,
7185 * lib/m4sugar/m4sh.m4: Likewise.
7186 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
7187 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
7189 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
7190 (.x.1): Ignore the time stamp in the .TH line when deciding whether
7191 to update the man page. That way, we don't have to check in new
7192 man pages every month.
7194 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
7195 quotes and backslashes. Patch from Derek Price.
7197 2005-06-10 Derek Price <derek@ximbiot.com>
7199 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
7202 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
7204 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7205 -u, since it outputs chatter if the input files are the same.
7206 Problem reported by Ralf Menzel.
7208 2005-06-08 Derek Price <derek@ximbiot.com>
7210 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7211 renaming them since they are about to be redefined anyhow.
7213 2005-06-08 Derek Price <derek@ximbiot.com>
7215 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7216 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7217 Move m4_undefine to alphabetical order.
7219 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
7221 * README: Recommend GNU M4 1.4.3 or later.
7222 * doc/autoconf.texi (Introduction): Likewise.
7223 Reword to avoid some formatting glitches.
7224 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7225 Clarify explanation of HP compiler bug.
7226 Redo example output tp match current CVS snapshot.
7227 Use @example.org in email addresses when the examples
7228 might get inadvertently cut-and-pasted into user code.
7229 Remove example of autom4te usage that doesn't seem to work now.
7230 Use modern AC_INIT (except when the example is meant to be
7231 shown with Autoconf 2.13).
7232 Update ksh info for Solaris 9 and later.
7234 Modernize description of Automake versions a bit.
7235 Don't claim a future version of Autoconf is near.
7236 * doc/install.texi: Reword to avoid some formatting glitches.
7238 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7240 * doc/autoconf.texi: Add [] to examples, so that the manual
7241 follows its own advice about quoting better.
7242 Reword to avoid some formatting glitches.
7243 * doc/installt.exi: Reword to avoid some formatting glitches.
7245 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7246 Tru64 ksh pattern matching bug. Reported against Libtool by
7247 Albert Chin <libtool@mlists.thewrittenword.com> and
7248 Nicolas Joly <njoly@pasteur.fr>.
7250 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7252 m4_cdr of one-member list was [[]] (one-member list containing an
7253 empty string) instead of [] (an empty list. Callers were skewed to
7254 match this misbehaviour. As a consequence of this:
7255 - m4_foreach([x], [], [foo]) expanded to `foo', while
7256 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7257 This bug has been fixed:
7259 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7260 expand to an empty string; print error msg if called without
7262 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7263 misbehaviour; handle [] and [[]] correctly.
7265 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7267 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
7268 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
7269 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
7271 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7273 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7274 swallow records with more than 99 fields.
7275 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7276 parse the long line.
7278 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7280 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7281 swallow literals longer than 399. Reported by Ralf Wildenhues.
7282 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
7283 to workaround this limitation.
7285 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
7287 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7288 to gfortran, and make these the first two compiler names
7289 checked (following the general autoconf preference for gcc).
7291 2005-06-03 Stepan Kasal <kasal@ucw.cz>
7293 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7294 (DISTCLEANFILES): Remove $(check_SCRIPTS).
7295 (testsuite): Make sure autotest.m4f is up-to-date before using it.
7297 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
7299 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7300 expression of unbounded size when processing the --list
7301 option. This runs afoul of a limit of 399 bytes per regular
7302 expression on AIX. Problem reported by Ralf Wildenhues.
7304 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
7306 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
7307 * doc/autoconf.texi (Particular Headers): Reword example
7308 for multiline stdbool replacement.
7309 (Setting Output Variables): Reword text a bit. Don't
7310 give all the details about |#_!!_#|.
7311 Reword description of line replacement.
7313 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7315 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7316 now contain newlines, and substituted files must be referenced on
7317 a line alone; the sed scripts to substitute them are now very
7319 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
7320 commands can be put in a sed script portably.
7321 * doc/autoconf.texi (Setting Output Variables): Document above
7322 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
7323 use of multiline substitution.
7324 * tests/torture.at: No longer expect substitution of newline to fail.
7326 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>

7329 From Ralf Menzel (trivial change).
7331 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
7333 * tests/local.at: Don't attempt to check for negated character
7334 classes in shell scripts. The test was too brittle.
7336 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7338 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
7339 * doc/autoconf.texi (Limitations of Builtins): Document this
7342 2005-05-24 Stepan Kasal <kasal@ucw.cz>
7344 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
7345 common code; used in many places in the tree.
7346 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
7347 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
7349 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
7351 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
7352 messages when ac_unique_file is not found.
7353 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7354 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
7355 commands, for consistency with AC_MSG_ERROR and such.
7357 * bin/autoconf.as: Make more use of "shift 2" in option processing.
7359 * bin/Makefile.am: Merge the two rules for creating scripts.

7367 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7369 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
7370 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7371 (ac_top_builddir): ... this ...
7372 (ac_top_build_prefix): ... to this; the old name is also kept, for
7373 backward compatibility.
7374 (ac_top_builddir_sub): New variable, without the trailing slash,
7376 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
7377 * doc/autoconf.texi (Configuration Actions): Rename
7378 ac_top_builddir to ac_top_build_prefix.
7379 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
7380 at_top_builddir to at_top_build_prefix.

7385 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
7388 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7390 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7391 argument to m4_foreach. I guess it was necessary in the past,
7392 but I think it's a no-op now.
7394 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7396 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7397 ``cat <<_ACEOF'' commands to one.
7398 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
7399 * lib/autoconf/status.m4: On various places, use expr instead of
7401 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
7402 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
7403 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7405 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
7406 the wrong patterns between ``case'' and ``esac.'' The previous
7407 code had false positives.

7475 * doc/autoconf.texi (Autoconf Language): Be more precise about
7476 quoting rules. Problems noted by Stepan Kasal.
7477 Also, throughout this document, be more careful about white space.
7478 "blank", "white space", and "space" all have different meanings
7479 and we should be careful to say what we mean.
7481 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>

7500 set by latest automake.
7502 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7504 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"

7522 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7524 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7526 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7528 * doc/autoconf.texi (External Software): Quadrigraphs are not
7529 processed correctly in AS_HELP_STRING; avoid this in the examples.
7530 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7531 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7532 comment and reduce m4_default([foo], []) to [foo].
7533 (m4_strip): Update the explanation.
7535 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7537 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7538 Remove core.conftest.* too; it's generated by Tru64 5.1.
7539 Problem reported by Jennis Pruett.
7540 * lib/autoconf/functions.m4
7541 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7542 Don't bother to remove core files; AC_RUN_IFELSE should do that
7545 2005-04-19 Stepan Kasal <kasal@ucw.cz>
7547 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

7591 whole-archive (-zallextract, -zdefaultextract) options in the hope of
7592 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
7593 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
7595 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
7597 * NEWS: The configure command now warns you if you attempt to use
7598 a directory whose name contains a special character like space,
7600 * doc/autoconf.texi (Installation Directory Variables): Allow
7601 "," in file names. Do not use \@; it's not a portable regexp.

7616 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
7618 * doc/autoconf.texi: Fix some systematic formatting problems.
7619 ".)" needs a following @: if not at the end of a sentence, and
7620 similarly for "!)". "etc." should be preceded by a comma.
7621 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
7623 2005-03-22 Bruno Haible <bruno@clisp.org>
7625 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
7626 argument is often called 'build-aux'.
7628 2005-03-07 Stepan Kasal <kasal@ucw.cz>
7630 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
7631 macro AC_TRY_LINK is obsolete.
7632 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
7635 2005-02-24 Stepan Kasal <kasal@ucw.cz>
7637 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
7638 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
7639 from a Common Lisp's `cl'.
7640 (AC_PROG_CXX): Behave according to the documentation: don't
7641 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
7642 make the variable CCC precious; use `cl.exe', not `cl'.
7644 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7645 Alexandre Duret-Lutz <adl@gnu.org>
7647 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
7648 /dev/null, as "configure" shouldn't read stdin, and this insulates
7649 us from problems (e.g., when testing for "cl"). Also, do this
7650 redirection before invoking "hostname" or "uname", and keep the
7651 original input stream available via...
7652 (AS_ORIGINAL_STDIN_FD): ... this new macro.
7653 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
7654 bother with "</dev/null" since it's now done at the top of

7665 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
7666 newline if neither \c nor -n work, as that would output two
7667 newlines. Prefer -n to \c. Reported by Stepan Kasal.
7669 2005-02-12 Stepan Kasal <kasal@ucw.cz>
7671 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
7672 This causes that any required macros inside will get before the if.
7673 * doc/autoconf.texi (autom4te.cache): A typo.
7675 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
7677 Undo previous change, except keep the change to
7678 lib/autoconf/programs.m4 that replaced grep with shell
7679 pattern-matching. This is because net-snmp configure reads stdin.
7680 Reported by Noah Misch.
7682 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
7684 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
7685 from /dev/null, as "configure" shouldn't read stdin, and this
7686 insulates us from problems (e.g., when testing for "cl").
7687 Suggested by Alexandre Duret-Lutz. Also, do this redirection
7688 before invoking "hostname" or "uname".
7689 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7690 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
7691 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
7692 "</dev/null" since it's now done at the top of 'configure'.
7693 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7694 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7695 Also, replace grep with shell pattern-matching, to save a process.
7697 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
7699 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7700 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
7701 avoid thinking that Allegro Common Lisp's "cl" command is a C++
7704 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
7706 * doc/autoconf.texi (Limitations of Usual Tools): Document that
7707 grep -q isn't portable. Improve grep -s explanation.
7708 Problem reported by Dan Manthey.
7710 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
7712 * doc/autoconf.texi (Special Shell Variables): Clarify

7715 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
7717 * doc/autoconf.texi: Use @acronym for DJGPP.
7718 Fix some @code's that should have been @env's, and vice versa.
7719 Sort environment variable names.
7720 Mention that shells no longer inherit IFS.
7721 Don't recommend PATH_SEPARATOR=';' so strongly.
7722 Mention that $RANDOM might expand to the empty string.
7723 "symlink" and "soft link" -> "symbolic link".
7724 Improve mktemp description (reported by Bruno Haible).

7764 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not

7800 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
7802 Try not to generated lines of unlimited length, as POSIX places a
7803 2047-byte limit on line length of portable text files.
7804 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
7805 Use newline as a separator, not space.

7863 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
7864 Update the long comment explaining it.
7866 m4_require no longer writes an ``is required by'' line to the
7867 execution stack. It contains only one bit of non-redundant
7868 information: that the macro was required, not called. And even
7869 this bit is useless in most situations: have you ever met a macro
7870 which both calls and requires the same macro?
7872 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
7873 (_m4_defun_pro_outer): ... only via this macro, for the outermost

7876 (m4_expansion_stack_pop): Remove the misplaced comment.
7877 (m4_require): Don't put the ``is required by'' line to the
7878 execution stack; slightly improve the out-of-a-defun error message.
7879 (_m4_divert_grow): New macro, counter for the temporary diversions.
7880 (_m4_require_call): Use it.
7881 * tests/m4sugar.at (m4_require): Expect output without the
7882 ``is required by'' messages.
7884 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
7886 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X

7920 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
7921 Warn about newline stripping in `` and $(). Update Solaris
7923 (Limitations of Builtins): Use expr "X...", not expr "x...", as
7924 X insulates us from future changes to Posix.
7925 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
7928 2005-01-19 Stepan Kasal <kasal@ucw.cz>
7930 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

7950 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
7952 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

7973 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
7974 (_m4_divert_n_stack): New macro; the expansion is
7975 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
7977 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
7978 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
7979 stored in _m4_divert_diversion or _m4_divert_dump.
7980 (m4_divert_pop): When the parameter is given, compare the symbolic
7981 name with the last diversion pushed on the stack. Previously, the
7982 current diversion was compared with the numeric value of the
7983 diversion given as the parameter.
7984 (m4_require): If the macro hasn't been expanded yet, call ...
7985 (_m4_require_call): this new macro.

8018 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
8019 signals that the package uses Automake; a `Makefile.am' is typical but
8020 not essential. Reported by Magnus Therning.

8543 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8544 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8545 Don't fail if ENV or BASH_ENV is readonly.
8546 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
8547 etc. are read only. Problem reported by Ludovic Courtes.
8549 2004-06-23 Noah Misch <noah@cs.caltech.edu>
8551 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
8552 zsh, disable GLOB_SUBST to avoid backslash handling problems.
8555 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
8557 * doc/autoconf.texi (File System Conventions): Warn about
8558 names like "aux". Problem reported by Eric Blake.
8560 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
8561 by zero instead of array size, so that we can use any arithmetic
8562 constant expression (instead of requiring an integer constant
8563 expression). This allows us to test expressions like DBL_MAX <
8564 LDBL_MAX, which didn't conform to the C standard using the old
8566 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
8567 now that we can do floating-point tests at compile time.
8569 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8571 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8572 and LDBL_EPSILON, as the resulting expression isn't an
8573 integer constant expression and violates the C standard.
8574 Problem reported by Nelson H. F. Beebe. Also, check
8575 for "L" suffix, and check that long double doesn't have
8576 worse range or precision than double, that mixed-mode
8577 arithmetic doesn't generate a diagnostic, that double
8578 constants fit in long double.
8580 2004-06-03 Kevin Ryde <user42@zip.com.au>
8582 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
8583 malloc(0) and realloc(NULL,size).
8585 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
8588 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
8590 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
8591 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
8594 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8596 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
8597 can be rewritten using if-then-else. Suggested by Bruno Haible.
8599 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
8601 * doc/autoconf.texi (testsuite Scripts): Fix typo.
8602 Problem reported by Stepan Kasal.
8604 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8606 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
8607 change). Patch reported by Ralf Wildenhues in
8608 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
8610 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8611 function F exists if the compiler and linker let you compile an
8612 expression like (F != 0). Recent versions of GCC optimize away
8613 the reference to F in that case, since every function address must
8614 be nonzero, so the link succeeds even if F does not exist.
8615 Problem reported by Manu in
8616 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
8618 * doc/autoconf.texi (Systemology): Standardize on the spelling of
8619 "Unix". Many uses changed.
8620 (Limitations of Builtins): Explain better why the ! command isn't
8623 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
8625 * lib/autom4te.in (Automake-preselections): Preselect
8626 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
8628 2004-05-19 Kevin Ryde <user42@zip.com.au>
8630 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
8631 referencing AC_FUNC_STRERROR_R.
8633 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
8634 note pessimistic assumption when cross compiling.
8636 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
8638 * doc/autoconf.texi (Limitations of Make): Note that BSD make
8639 (until 2004) invoked subcommands with sh -e, contra POSIX.
8640 Reported by Kevin Ryde.
8642 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
8644 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
8645 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
8646 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
8647 `test -f " /usr/bin/grep"', which _always_ failed.
8648 (AC_PROG_SED): Ditto bogus PATH fix.
8649 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
8650 requires that grep correctly supports _multiple_ `-e' options, rather
8651 than stating only that grep should accept `-e'.
8653 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
8655 Port to C99, which requires that 'exit' be declared.
8657 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
8658 to ensure that stdlib.h is included.
8659 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
8660 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
8661 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
8662 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
8663 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
8664 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
8665 when using 'exit' in a test; C99 requires that 'exit' be declared.
8667 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
8669 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
8670 now prefers 'grep' implementations that accept -e.
8671 (Limitations of Usual Tools): Describe problems of traditional
8672 egrep and fgrep with long input lines, and of traditional grep
8674 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
8675 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
8676 All callers changed. Append /usr/xpg4/bin to the PATH, for
8678 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
8679 the user with complaints about multiple -e options.
8680 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
8681 Define it with AC_PROG_GREP.
8682 * configure.ac (AC_PROG_GREP): Add.
8683 * lib/freeze.mk (GREP): New macro.
8685 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
8687 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
8688 a possible candidate only after all others fail, rather than
8689 consulting it first. This improves backward compatibility by
8690 better reflecting the way shell selection occurred in previous
8691 versions of Autoconf, and should help to avoid triggering latent
8692 problems in other packages, such as the one in Automake where zsh
8693 is not handled robustly:
8694 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
8695 Although it is not Autoconf's responsibility to work around
8696 problems in Automake, it nevertheless makes sense to avoid
8697 introducing unnecessary incompatibilites.
8699 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
8700 Gary V. Vaughan <gary@gnu.org>
8702 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
8703 how deeply nested we are when a suitable tool is found, set the
8704 ac_path_TOOL_found flag.
8705 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
8706 nested we are in this macro. Break out of all 3 nested loops if
8707 ac_path_TOOL_found is set.
8709 2004-04-21 Gary V. Vaughan <gary@gnu.org>
8711 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
8712 of the _AS_PATH_WALK loop too if GNU flavor is found.
8714 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
8716 * doc/autoconf.texi (Limitations of Make): Update documentation
8717 for `$<'. New entry `Long lines', based on a report from Simon
8718 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
8719 paragraph about DJGPP, based on a mail from Richard Dawe.
8721 2004-04-20 Paul Eggert <eggert@twinsun.com>
8723 * tests/c.at (C keywords): Don't assume that GCC supports
8724 "restrict" and "inline", as sufficiently-old GCC versions do not
8725 (also, GCC configured to be in pedantic C89 mode does not).
8726 Problem reported by Sumit Pandya in:
8727 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
8729 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
8730 consider -g to work if it generates warnings when plain compiles
8731 don't. Problem reported by Braden McDaniel in:
8732 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
8734 * doc/autoconf.texi (Slashes): New section, to document a problem

8738 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
8739 linker output files before linking, to work around IRIX 6 linker bug.
8740 Problem reported by Rainer Orth in:
8741 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
8743 2004-04-20 Gary V. Vaughan <gary@gnu.org>
8745 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
8746 best tool so far counter rely on the tool path variable name to
8747 avoid checks for one tool being affected by the results of running
8748 the length check on a previous tool.
8750 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
8751 match expression argument, as different greps have different
8752 regular expression flavours.
8753 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
8755 (AC_PROG_EGREP): Pass 'EGREP$'.
8756 (AC_PROG_GREP): Pass 'GREP$'.
8758 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
8760 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
8761 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.

8765 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
8766 Types, Specific Compiler Characteristics, System Services,
8767 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
8768 etc. consistently instead of 'long', 'short', 'unsigned' etc.
8769 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
8770 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
8772 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

8785 HAVE_STRUCT_TM_TM_ZONE is not defined.
8786 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
8787 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

8856 * bin/Makefile.am (edit): Don't use $< in a context where
8857 POSIX doesn't require support for it. Use $@.in instead.
8858 Problem reported by Anthony N. Frasso in
8859 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

8892 Darwin uses -lcrt2.o and there's little point to cataloging all
8893 the system variants. Partial fix reported by Andreas Waechter in:

9016 2004-01-26 Paul Eggert <eggert@twinsun.com>
9018 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9019 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9020 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9021 not <inttypes.h>. Problem reported by Tim Mooney in
9022 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9023 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9026 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9027 otherwise "make check" fails because it forbids cmp (I guess
9028 because cmp treats files as binary on DOS-like systems).
9030 * tests/mktests.sh: Update copyright date to 2004, since some tests
9031 have changed in 2004.
9033 2004-01-23 Gary V. Vaughan <gary@gnu.org>
9035 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
9036 non-truncating sed or gsed program in PATH.
9037 * tests/acprograms.at: Add it.
9038 * doc/autoconf.texi (Particular Programs): Document it.
9041 2004-01-15 Paul Eggert <eggert@twinsun.com>
9043 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9044 -std1 disables some useful extensions on Tru64. Problem reported
9046 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
9048 2004-01-14 Paul Eggert <eggert@twinsun.com>
9050 * doc/autoconf.texi (Programming in M4sh): Document that
9051 AS_MKDIR_P succeeds if the destination is a symbolic link
9052 to an existing directory.
9053 (Limitations of Usual Tools): Note that mkdir -p might not
9054 succeed on symlinks to directories.
9056 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9058 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

9072 2004-01-09 Paul Eggert <eggert@twinsun.com>
9074 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9075 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9076 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9077 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9078 AC_COMPILE_IFELSE, since we now assume our caller invokes
9079 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9080 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9081 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9082 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9084 2004-01-07 Paul Eggert <eggert@twinsun.com>
9086 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9087 `"'...'"`, as it's confusing (and I suspect it may not work on
9088 some platforms). The code was incorrect anyway, as it assumed
9089 that \$ evaluated to itself in that context. Reported by
9090 Alexandre Duret-Lutz.
9092 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9094 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

9124 Bug reported by David Relson in
9125 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9127 * Makefile.am (autom4te-update):
9128 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

9144 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9145 -c -o might not work. From a suggestion by Kevin Ryde.
9146 (C Compiler, Generating Sources, Limitations
9147 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9148 Don't put '-o' after non-options, as POSIX doesn't allow this.
9149 Mention that cc's name might be gcc or c89 or whatever.
9151 2004-01-04 Kevin Ryde <user42@zip.com.au>

9160 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9162 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9163 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
9164 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
9165 explanation clearer.

9176 * tests/atlocal.in: Store the result here.

9257 the expanded body, consistently with other macros such as AC_USG.
9259 2003-11-17 Paul Eggert <eggert@twinsun.com>
9261 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes

9450 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
9451 -mGLOB_options_string stuff for Intel ifc, which can cause
9452 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

9486 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
9487 arguments so that it can be used with syntax identical to
9488 AC_PROG_F77, and so that we can more easily decide to
9489 remove/deprecate the DIALECT optional argument in the future if it
9491 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
9492 non-freeform-supporting compilers. Document freeform flags.
9494 2003-10-03 Akim Demaille <akim@epita.fr>

9506 2003-10-03 Akim Demaille <akim@epita.fr>
9508 * configure.ac: Quotation and formatting changes.

9555 Problem reported by Lars J. Aas in
9556 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
9557 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
9558 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
9559 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
9561 2003-09-26 Akim Demaille <akim@epita.fr>
9563 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
9564 directory for AC_CONFIG_COMMANDS' first argument exists.
9565 This makes valid the invocation of _AC_SRCPATH that follows.
9566 Reported by Eric Sunshine.
9567 * doc/autoconf.texi (Configuration Commands): Adjust.
9569 2003-09-26 Akim Demaille <akim@epita.fr>
9571 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
9572 Reported by Ralf Corsepius.

9583 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
9584 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
9585 Problem reported by Eric Sunshine in:

9588 2003-09-26 Akim Demaille <akim@epita.fr>
9590 The test suite are sometimes assigning timings incorrectly.
9591 Reported by Henk Krus.
9592 Diagnosed by Nicolas Joly.
9594 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
9596 Instead of making AT_help a sequence of assignments to grow
9597 $at_help_all, just make AT_help_all be the growing contents of
9598 $at_help_all, and make a single assignment in...
9600 (at_times_skip): Flip the meaning and rename as...
9602 (AT_INIT): When summarizing the test that ran, remove
9603 $at_times_file after use, and check it is present before trying to
9606 2003-09-25 Akim Demaille <akim@epita.fr>
9610 * bin/Makefile.am (edit): Handle '@configure_input@'.
9611 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
9612 (ifnames): chmod -w.
9613 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
9614 executables, not bin/ executables! Otherwise all the magic needed
9615 to find non installed files is turned off. This caused a failure
9616 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
9617 as found in its environment (sent by tests/autoreconf): pointing
9618 to bin/autom4te that could not find its files.
9619 * tests/mktests.sh: Force the replacement of generated files, for
9620 the sake of "mv" program that are interactive when overwriting a
9622 * config/install-sh: Upgrade from CVS Automake.
9624 2003-09-23 Paul Eggert <eggert@twinsun.com>
9626 * doc/autoconf.texi (Limitations of Builtins): Document test -h
9627 versus test -L issues.
9629 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
9630 Paul Eggert <eggert@twinsun.com>
9632 Trivial change to support GCC's configuration procedure.
9633 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.

9668 willing to edit the output files.
9670 2003-09-10 Akim Demaille <akim@epita.fr>
9672 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
9674 * tests/mktests.sh: Skip AC_FC_SRCEXT.
9675 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
9677 2003-09-09 Akim Demaille <akim@epita.fr>
9679 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
9680 Reported by Gary Vaughan.

9695 2003-09-05 Paul Eggert <eggert@twinsun.com>
9697 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
9698 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
9700 2003-09-04 Akim Demaille <akim@epita.fr>
9702 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
9705 2003-09-04 Akim Demaille <akim@epita.fr>
9707 * bin/autom4te.in: Use &fatal where more appropriate than &error.

9711 2003-09-04 Akim Demaille <akim@epita.fr>
9713 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
9715 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
9717 Add support for newer Fortran dialects. The F77 interface is
9718 unchanged, and continues to support Fortran 77. New FC macros
9719 correspond to all the old F77 macros, with output variables FC,
9720 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
9721 available dialect, but older dialects can be specified. There are
9722 new macros AC_FC_SRCEXT to set the source extension, and
9723 AC_FC_FREEFORM to accept free-form source files.
9725 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

9756 2003-08-27 Akim Demaille <akim@epita.fr>
9758 * tests/m4sugar.at (cross_warning): Make sure to enable the
9759 output, so that we can track spurious m4sugar output.
9760 * tests/local.at: Require 2.57.
9761 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
9762 are defaulted by AT_CHECK anyway.
9763 Use AT_CHECK_AUTOM4TE.
9764 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a

9823 * bin/autom4te.in: Adjust to output the call stack.

9839 Use &verb, not &verbose.
9841 2003-08-21 Akim Demaille <akim@epita.fr>
9843 * bin/autoheader.in (&parse_args): Use &parse_warnings and
9845 ($help): Use Autom4te::ChannelDefs::usage.

9849 2003-08-21 Akim Demaille <akim@epita.fr>
9851 First stab at preserving warnings between calls to autom4te,
9852 including when the cache is used.
9854 There are still several issues: (i) there are too many runs of m4
9855 (one for include, one for warnings, and some more), (ii) warnings
9856 spreading on several lines are not handled gracefully, (iii) the
9857 code meant to have the call stack display for errors does not work
9858 (its handling should move from m4 to autom4te).
9860 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
9862 (@preselect): Add m4_warn.
9863 ($exit_status): Remove, use $exit_code.
9864 ($help): Use Autom4te::ChannelDefs::usage.
9865 (&handle_m4): No longer define the m4_warnings.
9866 At each run, extract and report the warnings.
9867 Always cache the result, including if the exit status is on
9868 failure, since if nothing changes, we should result in the same
9869 failure, hence we can use the cache.
9870 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
9871 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
9873 (m4_warn): Redefine as a do-nothing: it is its invocation that
9874 matters, as warnings are now reported via traces.
9875 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
9876 the contents of m4_warn: make it _call_ m4_warn, so that tracing
9877 the latter reveals calls to the former.
9881 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
9883 2003-08-21 Akim Demaille <akim@epita.fr>
9885 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

9893 (&parse_warnings): Accept a list of warning requests.
9894 (&usage): Return a string, not a side effect.
9895 (cross): New warning category.

9904 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
9905 * bin/autoscan.in: Adjust.
9907 2003-08-20 Akim Demaille <akim@epita.fr>
9909 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
9910 Reported by Alexandre Duret-Lutz.
9912 2003-08-20 Akim Demaille <akim@epita.fr>
9914 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
9915 * bin/autom4te: Adjust.
9916 In particular, be Autoconf tools are really silent when properly
9917 working, bind the verbosity of the 'note' channel to $verbose.
9918 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
9919 (&xsystem, &contents): Remove, since they are exported by...
9920 * lib/Autom4te/FileUtils.pm: this.

9981 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
9982 shorter column three. Add DESCRIPTION to log file content.
9984 2003-08-13 Derek Price <derek@ximbiot.com>
9986 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
9989 2003-08-12 Derek Price <derek@ximbiot.com>
9991 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.

10000 2003-07-31 Paul Eggert <eggert@twinsun.com>
10002 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
10003 in Bash 2.01. Problem reported by Brian Gough in
10004 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
10006 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
10008 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
10009 -lcrt1.o, for OS X. (trivial change)
10011 2003-07-07 Paul Eggert <eggert@twinsun.com>
10013 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
10014 inside '#ifndef __cplusplus'. Problem reported by
10017 2003-07-06 Bill Clarke <llib@computer.org>
10019 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10020 'long', not 'int', for benefit of Sun's recent C++ compilers
10021 (trivial change). See:
10022 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

10028 * lib/Makefile.am (autom4te.cfg): Make it read only.
10029 Depend on Makefile since it contains substitutions.
10030 From Paolo Bonzini.
10031 * lib/autom4te.in (args): Add local.at? for Autotest args.
10032 This change was made on autom4te.cfg which is generated.
10033 Reported by Raja R. Harinath.
10035 2003-06-25 Akim Demaille <akim@epita.fr>
10037 * doc/autoconf.texi (Header Portability): sys/mount.h.
10038 From Gareth McCaughan.
10040 2003-06-23 Akim Demaille <akim@epita.fr>
10042 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10043 not all of them. This fixes 1. the fact that when testing
10044 Autoconf there are many many config.log, 2. the incorrect use of
10045 top_srcdir to find config.log.
10046 Don't mix the detailed output of failed test with the summary of
10047 failures. Rather, append detailed log afterwards.
10049 2003-06-23 Akim Demaille <akim@epita.fr>
10051 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
10052 always run: output config.log on $at_group_log.
10054 2003-06-23 Akim Demaille <akim@epita.fr>
10056 * tests/torture.at (#define header templates): Don't use quotes in
10057 C++ comments as it puzzles Emacs' sh font-lock-mode.
10059 2003-06-23 Akim Demaille <akim@epita.fr>
10061 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
10062 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
10063 * tests/atspecific.m4: Rename as...
10064 * tests/local.at: This.

10070 2003-06-21 Kevin Ryde <user42@zip.com.au>
10072 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
10073 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
10074 ensuring we add -std1 for full-ANSI.
10076 * doc/autoconf.texi (hdrindex): New macro.
10077 Add index entries for portability of various standard header files.
10079 2003-06-20 Akim Demaille <akim@epita.fr>

10087 2003-06-20 Akim Demaille <akim@epita.fr>
10089 * bin/autom4te.in: Don't rely on $HOME being defined.
10090 Reported by Marc Espie as PR/233.

10105 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
10106 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
10107 (TEST_SCRIPT): New diversion.
10108 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
10109 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
10110 (AT_INIT): Support for expected failures.
10112 2003-06-02 Akim Demaille <akim@epita.fr>
10114 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
10116 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
10117 Autoconf nor Automake.
10118 (&contents): New, from Automake.
10121 2003-05-28 Paul Eggert <eggert@twinsun.com>
10123 * NEWS, doc/autoconf.texi (Particular Functions),

10129 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10130 (handle_exec_errors): New function. Work around $! being
10131 altered by WEXITSTATUS.
10132 (xqx, xsystem): Use handle_exec_errors.
10134 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10136 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10137 Do not call `_exit()', simply modify `$?'.
10138 (xsystem): Reset $! before running system, and check it afterward.
10139 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10140 63 for version mismatches.
10142 2003-05-23 Akim Demaille <akim@epita.fr>
10144 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10145 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10146 the middle of a line).
10147 * lib/m4sugar/m4sugar.m4: Likewise.
10148 Remove useless spaces in comments.
10150 2003-05-23 Akim Demaille <akim@epita.fr>
10152 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10153 exit 63, so that we (or Automake's "missing") can tell the
10154 difference with a plain failure.
10155 * doc/autoconf.texi (Notices): Adjust.
10157 2003-05-23 Akim Demaille <akim@epita.fr>
10159 * Makefile.am, bin/Makefile.am, config/Makefile.am,
10160 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
10161 White spaces cleanup.
10163 2003-05-22 Jim Meyering <jim@meyering.net>
10164 Paul Eggert <eggert@twinsun.com>
10166 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10167 Remove `#include <stdlib.h>' from the list; we should never
10168 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10169 resulting namespace pollution would cause other tests to fail.
10170 Configure scripts run with some older versions of g++ and HP's
10171 aCC would fail due to such an #include. Problems reported by
10172 Matthew Mueller in <http://bugs.debian.org/120704> and by
10174 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10175 In the test, use the test declaration before including <stdlib.h>,
10176 as that's closer to how it'll be used.
10178 2003-05-23 Akim Demaille <akim@epita.fr>
10180 * doc/autoconf.texi (Header Portability): ucred.h.
10183 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10185 Overhaul Autotest's logging: generate separate log files
10186 in testsuite.dir/NNN/testsuite.log, and append them to
10187 testsuite.log instead of re-running the test verbosely.
10189 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10190 file descriptor, write 0 to at_status_file instead of setting
10191 at_status=0, initialize some new variables (at_status_file,
10192 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10193 to rerun the tests, instead append the at_group_log to the
10194 at_suite_log when a test fails.
10195 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10196 with the AS_MESSAGE_LOG_FD redirected to stdout.
10197 (AT_CLEANUP): save the output status in $at_status_file
10198 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10199 its original place.
10200 (AT_CHECK): since tests are run with a redirected stdout,
10201 and used to be re-run in verbose mode, turn some $at_verbose
10202 into echo, and don't redirect the output of testing stdout
10205 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10206 the name of the debugging directory and information about
10209 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

10326 2003-05-06 Akim Demaille <akim@epita.fr>
10328 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10329 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10330 by aclocal.m4 is changed it might require the importing of another
10331 m4 extension file, i.e., aclocal must be run.
10333 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10334 (&parse_args): Use --force with aclocal if required and supported.
10335 (&autoreconf_current_directory): Use &run_aclocal.

10348 2003-04-29 Derek Price <derek@ximbiot.com>
10350 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10351 seperator with m4_append_uniq(). It doesn't work.
10352 (AT_CLEANUP): Add `;' to end of at_help_all.
10353 (AT_INIT): Allow --keywords to be specified more than once. When
10354 grepping $at_help_all for keywords, use the field and keyword
10355 seperators to ensure a complete keyword match. Alter at_prev handling
10356 to support the new --keywords behavior.
10358 2003-04-27 Karl Berry <karl@freefriends.org>
10360 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10361 align better with others. I also made some of the individual
10362 entries on one line, for brevity and to make it easier for me to
10363 sort my dir-example file in the Texinfo distribution :).

10424 Suggested by Paul Eggert.
10426 2003-03-28 Akim Demaille <akim@epita.fr>
10428 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
10429 reading the section "Present But Cannot Be Compiled" when the
10430 header causes problems.
10432 2003-03-28 Akim Demaille <akim@epita.fr>
10434 * tests/torture.at (Configuring subdirectories): Require aclocal
10435 1.4, otherwise the test fails, as it does support configure.ac.
10436 This fixes the "test 40 failed" bug reports.
10438 2003-03-28 Akim Demaille <akim@epita.fr>
10440 * doc/autoconf.texi (C Compiler): `#line' portability.

10507 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
10508 Tru64 make in the "target lookup" section.
10509 (Automake): Automake 1.5+ no longer requires special tools to be
10510 present on the developer's host.
10512 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
10514 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
10515 to a shell that can handle redirection or quoting correctly.
10516 Override SHELL with the shell detected by configure.
10517 Use of $^O suggested by Tim van Holder.
10518 * bin/autom4te.in (BEGIN): Likewise.

10522 * bin/ifnames.in (BEGIN): Likewise.
10524 * bin/ifnames.in: Add final newline to help and version messages.
10526 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
10527 to cope with DOS-style absolute paths, when constructing
10530 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
10531 When constructing paths with IFS=:, quote the path. If we're
10532 constructing a DOS-style absolute path, we don't want to split it

10555 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
10556 format starting with "-".
10558 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
10560 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
10561 is not portable inside Makefile.
10563 2003-02-20 Akim Demaille <akim@epita.fr>
10565 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
10566 compiler says yeah, but preproc says nope, compiler is right.
10567 Conversely, prompt the reader to send a bug report to the
10568 maintainers of the package, not of Autoconf.
10570 2003-02-20 Klee Dienes <kdienes@apple.com>
10572 * bin/autoreconf.in (autoreconf_current_directory): Properly
10573 handle an empty aclocal.m4.

10578 $ac_prefix_program.
10581 2002-12-23 Paul Eggert <eggert@twinsun.com>
10583 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10584 innocuous variant befor including <limits.h> or <assert.h>. This
10585 works around a bug reported by Albert Chin: HP-UX 11i
10586 (and earlier versions) have a <limits.h> that declares
10587 gettimeofday and many other functions.
10589 2002-12-03 Paul Eggert <eggert@twinsun.com>
10593 * NEWS, configure.ac: Update version.
10595 * doc/fdl.texi: Upgrade to FDL version 1.2.
10597 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
10598 nontrivially in main's body, so that f's external declaration is
10599 not optimized away in AIX. This should fix the bug reported by
10601 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
10603 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10604 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10605 defined, to support freestanding compilers. This should fix the
10606 bug reported by Momchil Velkov in
10607 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10609 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10610 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
10611 obsolete AC_CHECK_TYPE. The missing empty arg was reported
10612 by Simon Josefsson in
10613 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
10615 * Makefile.maint (www-gnu): New macro.
10616 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
10617 the location has moved.
10619 2002-12-02 Martin Frydl <martin@systinet.com>
10621 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
10622 \(.*\) match is too long and there is something more to be checked.
10623 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
10625 2002-11-15 Akim Demaille <akim@epita.fr>

10641 Update from masters.
10643 2002-11-14 Akim Demaille <akim@epita.fr>
10645 * Makefile.maint: Sync with Bison, i.e.:
10646 (po-check): Scan .l and .y files instead of the
10647 .c and the .h files that they generate. This fixes the bug
10648 reported by Tim Van Holder in:
10649 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
10650 Look for N_ as well as for _. Try to avoid matching #define for
10654 2002-11-14 Akim Demaille <akim@epita.fr>
10656 * doc/autoconf.texi (C Compiler): Compiling several files at once.
10657 From Paul Eggert and Albert Chin-A-Young.
10659 2002-11-14 Akim Demaille <akim@epita.fr>
10661 * doc/autoconf.texi (C Compiler): Solitary backslashes.
10662 From Paul Eggert and Albert Chin-A-Young.
10664 2002-11-14 Kevin Ryde <user42@zip.com.au>
10666 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
10667 than assigning in main, to avoid HP cc +O3 optimizing it away.
10669 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
10671 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
10672 option. Process --recheck after parsing all options. Pass -q
10673 option to configure on --recheck.
10674 (AC_OUTPUT): Pass -q from configure to config.status.
10675 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
10676 arguments to record.
10677 * doc/autoconf.texi (config.status Invocation): Document
10678 config.status -q option.
10680 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
10682 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
10683 Makefile.in if Makefile.am exists.
10684 (output): Strip `.am' from Makefiles. Don't
10685 output AC_CONFIG_FILES if no Makefiles were found.
10687 2002-11-07 Akim Demaille <akim@epita.fr>
10689 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.

10705 Reported by Ezra Peisach.
10707 2002-11-05 Akim Demaille <akim@epita.fr>
10709 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
10711 We _have_ to stop using the old compatibility scheme that tried to
10712 avoid useless backslashes because Libtool 1.4.3 contains a
10713 AC_DEFINE([error_t], [int],
10714 [Define to a type to use for \`error_t' if it is not
10715 otherwise available.])
10716 We _have_ to quote the single quote and backslashes with \. The
10717 old compatibility scheme saw that ` was backslashed, and therefore
10718 did not quote the single quote. Hence before this patch, Autoconf
10719 was not compatible with Libtool.
10721 2002-11-04 Paul Eggert <eggert@twinsun.com>
10723 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

10728 2002-11-04 Akim Demaille <akim@epita.fr>
10732 * Makefile.maint (update, cvs-update, po-update, do-po-update):
10734 * config/texinfo.tex: Update.
10736 2002-11-03 Akim Demaille <akim@epita.fr>
10738 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
10740 (&autoreconf): here.
10741 ($help, $make, &parse_args, &autoreconf_current_directory):
10743 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10745 2002-10-31 Bruno Haible <bruno@clisp.org>

10763 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
10764 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
10765 Make variable, not a shell variable.
10766 Suggested by Bruno Haible.
10768 2002-10-31 Akim Demaille <akim@epita.fr>
10770 * bin/autom4te.in (load_configuration): Reject #args out of any
10773 2002-10-31 Akim Demaille <akim@epita.fr>
10775 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
10776 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)

10789 2002-10-29 Paul Eggert <eggert@twinsun.com>

10792 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
10793 Problem reported by Bruno Haible.
10795 2002-10-29 Akim Demaille <akim@epita.fr>
10797 * doc/autoconf.texi (Header Templates): Put also in words what the

10799 (Customizing autom4te): s/--cache=/--cache /.
10801 2002-10-29 Akim Demaille <akim@epita.fr>
10803 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
10805 sparc_address_test returns void.
10806 Use it with an argument, as prototyped.
10809 2002-10-29 Akim Demaille <akim@epita.fr>

11108 Because of caching, some files that no longer exist and are no
11109 longer required can still cause errors.
11110 Reported by Alexandre Duret-Lutz.
11112 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

11116 (&freeze): Use &error.
11117 (&up_to_date): If a file that was included according to the cache

11132 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11133 if some file was changed instead of `print'.
11134 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

11168 file name to enable parallel executions.
11169 From Sam Varshavchik.
11171 2002-10-08 Akim Demaille <akim@epita.fr>
11173 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11174 aclocal invocation, as Gettext macros might not be visible to
11176 Instead of blindly running autopoint, scan configure.ac (not the
11177 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11178 Reported by Paul D. Smith.
11180 2002-10-08 Paul Eggert <eggert@twinsun.com>
11182 Work around problems found when POSIXLY_CORRECT=1 is set.
11183 None of this seems to have anything to do with POSIX, really,
11184 but it's how Perl getopt works.
11185 * bin/autom4te.in (parse_args): Configure GetOpt with
11187 * doc/autoconf.texi (Invoking autom4te):
11188 --warning -> --warnings.

11210 * tests/torture.at (Configuring subdirectories): Be robust to
11211 users who use config.site to require for a cache: in this case,
11212 the two last configure runs, using two different sets of
11213 arguments, trigger a legitimate error.
11215 2002-09-28 Akim Demaille <akim@epita.fr>

11250 tests/autom4te itself.

11252 (autoscan.list): New target --this file is no longer a source.

11260 tracking changes in autoscan.list.
11261 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11263 2002-09-28 Akim Demaille <akim@epita.fr>

11279 2002-09-28 Akim Demaille <akim@epita.fr>
11281 From now on, autoscan files must always map a macro name to a

11284 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11286 * lib/autoscan/functions, lib/autoscan/headers: Make the macro

11379 2002-09-13 Akim Demaille <akim@epita.fr>
11381 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals

11452 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11453 (ifnames, autoscan, autom4te): Since we don't only depend on
11454 configure.ac variables (such as VERSION etc.), but also on prefix
11455 and so forth, depend on Makefile, not configure.ac.
11456 Reported by Alexandre Duret-Lutz.

11459 2002-09-05 Kevin Ryde <user42@zip.com.au>

11480 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11481 as of today, on Automake's team suggestion.
11483 2002-09-03 Akim Demaille <akim@epita.fr>
11487 2002-09-02 Akim Demaille <akim@epita.fr>
11489 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
11491 * configure.ac: Disable SITE_MACRO_DIR.
11493 2002-09-02 Jim Meyering <meyering@lucent.com>
11495 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11496 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11497 Also, tweak grammar: s/make sure to/be sure to/.
11499 2002-09-02 Paul Eggert <eggert@twinsun.com>
11501 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11502 directory names are generally preferable to physical names.
11504 2002-09-02 Akim Demaille <akim@epita.fr>
11506 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11507 Reported by Raja R. Harinath.
11508 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11509 * bin/autoupdate.in: Use error instead of die.
11511 2002-09-01 Paul Eggert <eggert@twinsun.com>
11513 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11514 ordinary shell concatenation rather than echo+tr+sed command that
11515 runs afoul of a long-line-related sed bug in Solaris 8.
11517 * bin/autoheader.in (parse_args): --warning -> --warnings.
11519 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11520 stdout, as traditional "ls" does.
11521 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11522 _AC_COMPILER_EXEEXT_O): Likewise.
11523 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11525 * bin/autoconf.as: Add --prepend-include option. This patch was
11526 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11527 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11529 * bin/autoconf.in, configure: Regenerate.
11531 * doc/autoconf.texi (Special Shell Variables): Mention
11532 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11534 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11535 MAILPATH and set PS1, PS2, PS4 to default values, to work
11536 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11537 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11538 the Autoconf documentation specifies; fall back to "unset" only if
11539 this fails. Use a shell for-loop for this rather than an m4 loop,
11540 to shorten the output script.
11542 2002-08-30 Paul Eggert <eggert@twinsun.com>
11544 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11545 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11546 for the CDPATH problem. Document PWD.
11547 (Limitations of Builtins): Document the problem that "cd $foo" and
11548 "ls $foo" may refer to different directories in shells conforming
11549 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11550 example, since the old example is now out of date.
11552 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11553 FOO" and "ls FOO" talk about different directories; this catches
11554 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11557 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11558 of rolling our own unset.
11559 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
11560 in practice we needn't worry about CDPATH if unset doesn't work.
11562 * Makefile.in, aclocal.m4, bin/Makefile.in,
11563 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
11564 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
11565 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
11566 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
11567 tests/Makefile.in: Regenerate with Automake 1.6.3.
11569 * config/config.guess, config/config.sub, config/mkinstalldirs:
11572 * configure: Regenerate with self.
11574 2002-08-30 Kevin Ryde <user42@zip.com.au>
11576 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"

11581 * bin/autom4te.in (Request::load): Correctly test for "do" read
11584 2002-08-29 Akim Demaille <akim@epita.fr>
11586 * lib/Autom4te/General.pm (&xqx): New.
11587 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11588 hand, which is not portable.
11590 * bin/autom4te.in: Use them.
11591 Use &error instead of die.
11592 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11595 2002-08-17 Paul Eggert <eggert@twinsun.com>
11597 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
11598 default list of compilers to try, since it was long ago superseded
11599 by the ksh fc builtin. Suggested by Steven G. Johnson.
11601 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
11603 * doc/autoconf.texi (Invoking autom4te): End the option table,
11604 fixing a bug introduced by the previous patch.
11605 (Limitations of Make): Add a 'target lookup' subentry in the
11606 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
11608 2002-07-29 Mark D. Roth <roth@feep.net>
11610 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
11611 options and use $AUTOM4TE_PATH.
11612 * doc/autoconf.texi: Remove documentation of autom4te
11613 --include-envvar and --site-macro-subdir options and document
11614 use of $AUTOM4TE_PATH.
11615 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
11616 arguments from each language section.
11618 2002-07-29 Paul Eggert <eggert@twinsun.com>
11620 * doc/install.texi: Include copyright symbol in copyright notice.
11622 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
11624 (AM_MAKEINFOFLAGS): New macro.
11625 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
11626 * Makefile.am (INSTALL): Use the new macros.
11627 Use -o rather than --output, since "missing" does not grok --output.
11629 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11631 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
11632 comments do not always work. Never trust the exit status of
11635 2002-07-24 Kevin Ryde <user42@zip.com.au>
11637 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
11638 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
11640 2002-07-23 Paul Eggert <eggert@twinsun.com>
11642 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
11643 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
11644 apparently treats PATH="nonexistent" as if it contained ".".
11645 Bug reported by Stefan `Sec' Zehl.
11647 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11649 * doc/autoconf.texi (Limitations of Make): Mention the special

11771 2002-06-27 Paul Eggert <eggert@twinsun.com>
11773 * config/install-sh: Quote $src. Prefer || to test's -o option,
11774 as per "Limitations of Builtins".
11775 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
11776 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
11778 * tests/mktests.sh: Use grep instead of fgrep, as per
11779 "Limitations of Builtins".

11784 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
11785 so that we consistently test the just-built programs.
11786 * tests/wrappl.as: Likewise.
11788 2002-06-12 Paul Eggert <eggert@twinsun.com>
11790 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

11799 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
11802 2002-06-11 Andreas Schwab <schwab@suse.de>
11804 * doc/autoconf.texi: Add more dir entries.
11806 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
11808 * bin/autom4te.in ($cache): Don't define using `$me', the name
11809 of the cache should not depend on the name under which autom4te

11863 * doc/autoconf.texi (Configuration Links): Likewise.

11866 2002-06-05 Paul Eggert <eggert@twinsun.com>

11894 * NEWS, doc/autoconf.texi (Particular Types): Document it.

11901 version of Autoconf that is discussed.
11903 2002-05-22 Paul Eggert <eggert@twinsun.com>
11905 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
11906 from the default list of compilers to try. Suggested by
11908 * NEWS: Document the above.
11909 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
11911 2002-05-17 Paul Eggert <eggert@twinsun.com>
11913 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
11914 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
11915 This improves on an earlier suggestion by H. Peter Anvin.
11917 2002-05-16 Paul Eggert <eggert@twinsun.com>
11919 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
11920 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
11921 Both macros now accept an optional source-dir arg.
11922 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
11924 * NEWS: Document this.
11925 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
11927 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
11928 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
11929 not for GNU extensions; this undoes part of the 2000-11-03 change,
11930 reverting to 2.13-compatible behavior.
11931 Add new optional argument DIR.
11932 (AC_FUNC_FNMATCH_GNU): New macro.
11934 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
11936 2002-05-08 Paul Eggert <eggert@twinsun.com>
11938 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
11939 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
11940 and it causes a 'test' syntax error if it fails.
11941 Bug reported by Stephen Gildea.
11943 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
11944 If prototypes are supported, use them to check this at compile-time,
11945 instead of trying to check it at run-time. If we must do a run-time
11946 check, assume that setvbuf is standard when cross-compiling, as
11947 nonstandard setvbuf occurs only on ancient and unlikely hosts.
11948 Bug reported by Paul D. Smith.
11950 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
11951 argument specifying location of getloadavg.c. This removes a
11952 FIXME. This idea was taken from Jim Meyering's implementation in
11954 * doc/autoconf.texi (Particular Functions): Document this.
11955 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
11956 that's what the code does; this fixes a bug reported by
11959 2002-05-03 Akim Demaille <akim@epita.fr>
11961 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
11962 autopoint instead of gettextize.
11963 ($uses_alocal): Rename as...
11964 ($uses_aclocal): this.
11965 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11966 Suggested by Bruno Haible.
11968 2002-05-03 Akim Demaille <akim@epita.fr>
11970 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
11972 2002-04-29 Paul Eggert <eggert@twinsun.com>
11974 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
11975 files to be 1 second older; just set them to be the same time.
11976 Also, sleep 1 second after the first aclocal, to work around
11977 problems with sub-second time stamps on the input files.
11979 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
11981 * doc/autoconf.texi: Mention "set -e -x" lossage
11982 under node "Limitations of Builtins".
11984 2002-04-29 Akim Demaille <akim@epita.fr>
11986 * doc/install.texi: Better wording for setting variables when
11988 From Christian Cornelssen.
11990 2002-04-29 Akim Demaille <akim@epita.fr>
11992 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
11993 of lack of $LINENO support, then the test will compare the $LINENO
11994 in testsuite vs. the lineno in the test file. This is wrong, of
11996 Be sure to protect it.
11997 Reported by Patrick Welche.
11999 2002-04-25 Akim Demaille <akim@epita.fr>
12001 * doc/autoconf.texi (Obsolete Macros): Typo.
12002 Reported by Vladimir Volovich.
12004 2002-04-25 Akim Demaille <akim@epita.fr>
12006 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12007 than some of the input files, hence, on the second run of aclocal,
12008 if some of its input are younger, make them older.
12009 Suggested by Paul Eggert.
12011 2002-04-25 Akim Demaille <akim@epita.fr>
12013 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

12019 and ac_subst_vars be sh variables containing the list of
12020 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12022 (_AC_INIT_PREPARE): Use them to log them.
12023 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12024 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12025 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12026 _AC_SUBST_FILES and _AC_SUBST_VARS.
12027 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12029 2002-04-24 Akim Demaille <akim@epita.fr>
12031 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12032 autoheader, so that automake does not complain about a missing
12033 config.h.in that was to be created.
12035 2002-04-23 Akim Demaille <akim@epita.fr>
12037 * bin/autoheader.in (parse_args): --warning takes an argument.
12040 2002-04-22 Peter Eisentraut <peter_e@gmx.net>

12087 Minor spelling and grammar fixes.
12089 * doc/autoconf.texi: Follow the outline suggested in the GNU
12090 Sample Texts sections of the Texinfo 4.2 manual. Most
12091 importantly, this makes sure that the copyright notices appear in
12092 all output formats. You probably need Texinfo 4.2 to generate
12095 Fix some bugs when using "$@" when there might be zero positional
12096 arguments in cases where this matters.

12116 * tests/c.at: We can't have zero arguments, so remove workaround
12117 that is not portable to Zsh.
12119 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
12121 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
12122 from aclocal.m4 too.
12124 2002-04-12 Akim Demaille <akim@epita.fr>
12126 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
12128 2002-04-10 Akim Demaille <akim@epita.fr>
12130 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
12131 workaround for ${1+"$@"}.
12132 * doc/autoconf.texi (Shell Substitutions): Explain it.
12133 From Oliver Kiddle and Peter Stephenson.
12135 Have M4sh perform minimal shell sanitizing.
12137 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12139 (_AS_PREPARE): this new macro.
12141 (AS_INIT): Invoke AS_SHELL_SANITIZE.
12142 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
12144 Adjust Autoconf and Autotest.
12146 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12147 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12148 * lib/autotest/general.m4 (AT_INIT): Likewise.
12149 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
12150 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
12153 Use this M4sh to generate Autoconf's shell scripts.
12155 * tests/wrapsh.as: New, precursor of wrapsh.in.
12156 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12157 on Autotest and M4sh.
12158 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12159 (wrapsh.in): New target.
12160 * bin/autoconf.as: New, precursor of autoconf.in.
12161 (autoconf.in): New target.
12163 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

12175 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
12176 (Portable Shell): Cross reference to Systemology.
12178 2002-04-05 Akim Demaille <akim@epita.fr>
12180 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
12181 directories when descending in a SUBDIRS.
12182 Reported by Ezra Peisach.
12184 2002-04-04 Andreas Schwab <schwab@suse.de>
12186 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
12187 contains no literal separators.
12189 2002-04-03 Akim Demaille <akim@epita.fr>
12191 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
12192 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
12193 Use dnl, not the KILL diversion.
12195 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12196 (AC_CONFIG_LINKS): here.
12198 Don't use the KILL diversion, as it kills spurious output, which
12199 results in failures being hidden.
12200 Use m4_defn where appropriate.
12201 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12202 after the second argument.
12204 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12205 syntax, as it is provided by M4sugar.
12206 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
12208 2002-04-03 Andreas Schwab <schwab@suse.de>

12227 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12229 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12230 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12231 (AC_PROG_CC): Call _AC_PROG_CC_STDC.

12233 (AC_C_CONST): Same.
12234 (AC_C_INLINE): Same.

12245 2002-03-28 Kevin Ryde <user42@zip.com.au>
12247 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12248 to avoid versions of HP C which don't allow that.
12250 2002-03-27 Paul Eggert <eggert@twinsun.com>
12252 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12253 (AS_SHELL_SANITIZE): Invoke it.
12254 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

12264 2002-03-25 Paul Eggert <eggert@twinsun.com>
12266 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12267 as POSIX requires, as it doesn't work with Zsh.
12268 * doc/autoconf.texi (Assignments): Document the problem.
12270 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12272 * doc/autoconf.texi (Limitations of Make): Mention more issue
12273 about VPATH, overriding of macros in sub-makes, and handling of
12276 2002-03-21 Paul Eggert <eggert@twinsun.com>
12278 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12279 problem with here-document buffer boundaries.
12281 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12282 when reinvoking the shell, to work around problems with installers
12283 who put strange things like "cd" commands in their environments.

12305 2002-03-18 Paul Eggert <eggert@twinsun.com>
12307 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12308 (Limitations of Usual Tools): Add mkdir section.
12310 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12311 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12312 back on AS_DIRNAME to compute prefixes otherwise; this is
12313 roughly what mkinstalldirs does. That way, we need not have
12314 our own filename disassembler. The old disassembler did not
12315 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12317 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12318 Create at_test_all by a series of assignments,
12319 not by a single assignment of a long string. The latter causes ksh
12320 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12321 presumably because of a buffer overrun.
12323 2002-03-14 Paul Eggert <eggert@twinsun.com>
12325 * lib/autotest/general.m4 (at_times_skip):
12326 Renamed from at_times. Now a boolean.
12327 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12328 says 'times: not found'.

12360 does not do it if --with-lispdir is given.

12369 subdirectory should exist.
12371 2002-03-08 Akim Demaille <akim@epita.fr>
12373 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12375 2002-03-08 Akim Demaille <akim@epita.fr>
12377 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12378 aliases the actual variables, and modifications of the former
12381 2002-03-08 Akim Demaille <akim@epita.fr>
12383 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12384 because of C-c: have m4 output in tmp files, then mv them.
12386 2002-03-08 Akim Demaille <akim@epita.fr>

12405 2002-03-04 Akim Demaille <akim@epita.fr>
12407 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
12408 * lib/autoconf/general.m4 (AC_INIT): More informative error
12409 message for LIBOBJ.

12418 * doc/autoconf.texi (Transforming Names): Equality between target
12419 and host is irrelevant.
12420 (Specifying Names, Canonicalizing): Remove all references to the
12421 backward compatibility hooks. Rather, collect them all into...
12422 (Hosts and Cross-Compilation): this new section.
12423 * doc/install.texi (System Type): Ditto.
12424 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12425 that `--host' implies cross-compilation.
12427 2002-03-04 Akim Demaille <akim@epita.fr>
12429 * doc/autoconf.texi (Evaluation Macros): New.
12430 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12432 (_m4_foreach): Define the variant with immediate evaluation so
12433 that it contains exactly the items, not an expression which
12434 evaluation is the current item.
12435 (m4_re_string, m4_re_word): Don't over quote them.
12437 2002-03-04 Akim Demaille <akim@epita.fr>
12439 Instead of having stacking `shift's evaluated at the end, let
12440 `foreach' loops immediately evaluate them.
12442 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12443 $*. This is the n-th time I change my mind, but hopefully this is
12446 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12448 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12449 it was only a hack for m4_text_wrap.
12450 (m4_car2): Remove, replaced by...
12452 (_m4_foreach): Adjust.

12506 AC_PREFIX_PROGRAM fails with dashed program names
12508 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

12527 sure not to introduce newlines in at_groups.

12542 cross-compilers, too. This undoes some of the most recent change
12545 2002-02-05 Akim Demaille <akim@epita.fr>
12547 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
12548 to make sure they are up to date when `check' is run.
12550 2002-02-05 Akim Demaille <akim@epita.fr>

12564 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
12565 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
12567 2002-02-05 Akim Demaille <akim@epita.fr>

12570 optional are the sum of the previous files on the command line'.
12571 Also, pass `--reload-state=' on them, so...
12572 (handle_m4): don't.
12573 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
12574 (M4sh): Rely on M4sugar.

12612 2002-01-28 Akim Demaille <akim@epita.fr>
12614 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12615 AUTOTEST_PATH *after* it was set.
12616 Don't put `.' in the PATH: the user should be precise and `./' if
12617 needed. In addition, given that the test suite does some `cd', if
12618 `.' is in the path, the `tested programs' sections will report
12619 programs found in the test suite's directory, while during the
12620 tests (performed in their own directory), these programs are no
12621 longer visible. In other words, the results is confusing and
12623 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

12667 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
12668 message on invalid options.
12669 * bin/autom4te.in (parse_args): Don't use
12670 Autoconf::General::getopt with non valid options.
12672 2002-01-17 Jim Meyering <meyering@lucent.com>
12674 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
12675 $ac_cv_exeext so we don't use an old, invalid, cached value.

12691 * doc/autoconf.texi (testsuite Scripts): Adjust.
12692 * tests/Makefile.am (package.m4): New.
12693 EXTRA_DIST it since its a source.
12695 2002-01-06 Akim Demaille <akim@epita.fr>
12697 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
12698 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
12699 and PACKAGE_BUGREPORT from here...
12700 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
12702 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
12703 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
12704 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
12705 * tests/tools.at (autoheader): Adjust.

12727 2001-12-14 Akim Demaille <akim@epita.fr>
12729 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
12730 trailing files, don't apply `-rf' to files which might not be
12731 created by configure (core, core.*, and *.core), but just `rm -f'.
12732 Suggested by Jonathan Kamens.
12734 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
12736 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

12758 2001-12-12 Kevin Ryde <user42@zip.com.au>
12760 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
12761 forbidden file descriptors table.
12763 2001-11-26 Akim Demaille <akim@epita.fr>

12771 Remove $filepath, useless.
12772 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
12773 variables, they are really part of the tokens.
12774 Split the input line on spaces and then look for tokens.
12775 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
12776 because of `lex$U.$(OBJEXT)'.
12777 (&scan_files): Use "@list" instead of join.
12778 * doc/Makefile.am (CLEANFILES): Add *.fns.

12783 Remove, replaced by...
12784 * tests/wrappl.in: Be common for all the Perl executables.
12785 In particular autoscan and autoheader want -I.
12786 * configure.ac: Adjust.
12787 * lib/autoscan/headers: errno.h is portable.
12789 2001-11-26 Akim Demaille <akim@epita.fr>

12816 Test groups are now run two directories deeper.

12821 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
12822 top_srcdir, builddir and top_builddir.
12823 Use `at_*dir' relatively to the directory containing the
12824 suite, use `*dir' when relatively to the current group dir.

12833 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12835 * doc/autoconf.texi (Using System Type): Add an example of `case
12836 $host' usage so people quit using `case $target' everywhere.
12838 2001-11-22 Akim Demaille <akim@epita.fr>
12840 * doc/autoconf.texi (Installation Directory Variables): Englishoes
12841 spotted by Jim Meyering.
12843 2001-11-16 Paul Eggert <eggert@twinsun.com>
12845 This patch implements a `long double' suggestion by Oliver Kiddle.
12847 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
12848 static, to catch errors if the value isn't known at compile-time
12849 and the compiler supports dynamic arrays. Change its name from
12850 `_array_' to `test_array' to avoid potential name clashes.
12851 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
12852 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
12853 better than double. Catch a bug in GCC 2.95.2 x86.
12854 * doc/autoconf.texi (C Compiler): Document the above.
12857 2001-11-13 Akim Demaille <akim@epita.fr>
12859 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
12861 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
12863 2001-11-13 Akim Demaille <akim@epita.fr>
12865 * lib/autotest/general.m4 (AT_INIT): After having run the test
12866 group, go back to the initial directory, not to at_suite_dir.
12868 2001-11-13 Akim Demaille <akim@epita.fr>
12870 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
12871 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
12872 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
12874 (AT_CHECK_CONFIGURE): Use absolute paths.
12875 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
12876 The problem is still the old one: there is no means in M4 (that I
12877 know about) to create a defining macro, because there is no means
12878 to create `$1' etc., therefore, the defining macro ``swallows''
12879 all the arguments meant to the defined macro.
12881 2001-11-13 Akim Demaille <akim@epita.fr>
12883 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.

12890 * lib/autotest/general.m4: Change `tests?' into `groups?' in
12891 variable names when referring to a single test group, or to
12892 `suite' when referring to the whole test suite.
12893 `at_last_test' is removed: m4 compute at_format itself.
12894 (at_stdout, at_stder1, at_stderr): New variables.
12895 (AT_CHECK): Use them.
12897 2001-11-13 Akim Demaille <akim@epita.fr>
12899 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
12901 Create `testsuite.dir/003/run' instead of `testsuite.003'.
12902 Do it as soon as a test fails, don't wait till the end of the test
12904 Don't remove $as_me.[0-9]*, since these files no longer exist.
12906 2001-11-13 Akim Demaille <akim@epita.fr>
12908 * tests/tools.at: Use absolute paths, since we are no longer run
12911 2001-11-13 Akim Demaille <akim@epita.fr>
12913 Now that tests are running in their own private dir, there is no
12914 need to list the files to remove at the end of tests groups.
12916 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
12917 (AT_data_files, at_data_files): Remove.
12918 (AT_CLEANUP, AT_DATA): Simplify.
12920 Remove the group dir if !debug && !failed.
12921 * tests/atspecific.m4: Adjust.
12923 2001-11-13 Akim Demaille <akim@epita.fr>
12925 Start a new layout for Autotest: `testsuite' creates
12926 `testsuite.dir' in which the at-check-line etc. files are to be
12927 found, and `testsuite.dir/003' where the test group 3 is run.
12929 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
12930 at_check_line_file, at_format, at_test_normalized, at_group_dir
12932 Create the directories.
12933 Use absolute paths for at- files.
12934 (AT_CHECK): Adjust.
12936 2001-11-11 Michael Matz <matz@kde.org>
12938 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
12940 (m4_car): Properly quote arguments.
12942 2001-11-13 Akim Demaille <akim@epita.fr>
12944 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
12945 with stricter rules on LIBOBJS.
12947 2001-11-12 Paul Eggert <eggert@twinsun.com>
12949 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
12950 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
12953 2001-11-12 Akim Demaille <akim@epita.fr>
12955 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.

12962 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
12963 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
12964 specify to what the macro should be defined (typically to 1).

12971 2001-11-12 Akim Demaille <akim@epita.fr>
12973 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
12974 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
12975 definition used by Automake where LEX is +/- "${missing} lex" and
12976 `missing' itself contains variables.
12978 2001-11-12 Akim Demaille <akim@epita.fr>
12980 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
12981 Now that M4sh pushes BODY, the comments were output at the end of
12984 2001-11-08 Akim Demaille <akim@epita.fr>
12986 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
12987 that we can trace macros from aclocal.m4.
12988 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
12989 obsoleted, and redirect to the former anyway.
12990 Reported by Ralf Corsepius.
12992 2001-11-08 Akim Demaille <akim@epita.fr>
12994 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
12995 processed only if present.
12996 * tests/torture.at (Configuring subdirectories): Use autoreconf
12997 instead of successive calls to autoconf.
12998 Add a nonexistent subdirectory to exercise the patch above.
12999 Reported by Ralf Corsepius.
13001 2001-11-08 Kevin Ryde <user42@zip.com.au>
13003 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc

13022 * tests/Makefile.am (testsuite): Rename this target as...
13023 ($(TESTSUITE)): this.
13026 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13028 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13029 the --prefix option, also remove it's argument.
13031 2001-11-05 Akim Demaille <akim@epita.fr>
13033 * doc/autoconf.texi (testsuite Invocation): Update.
13034 (Writing testsuite.at): Update.

13043 (&file_name_is_absolute): New, wrappers around routines from
13045 Use and export them.
13046 (&find_configure_ac): Optionally take a directory where to look at.
13047 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13049 Default @ARGV to `.', not find_configure_ac.
13050 (&autoreconf): Argument is a directory.
13051 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13052 * doc/autoconf.texi (autoreconf Invocation): Update.
13054 2001-11-03 Akim Demaille <akim@epita.fr>
13056 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13057 (@export_forward_subs): New.
13058 Add basename, dirname, and fileparse.
13060 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13061 Don't look for aclocal flags if we already know aclocal is not
13063 Move aclocal.m4t only if it exists.
13064 Reported by Ezra Peisach.
13066 2001-11-03 Akim Demaille <akim@epita.fr>
13068 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13069 passed on command line, defaulting to ./configure.ac if present.
13070 (&maybe_autoreconf, File::Find): Remove, unused.
13071 (&autoreconf): If autoconf is not used, don't try to trace.
13073 2001-11-02 Akim Demaille <akim@epita.fr>
13075 * configure.ac: Bump to 2.52g.

13081 2001-11-02 Akim Demaille <akim@epita.fr>
13083 * config/config.guess, config/config.sub, doc/standards.texi:
13084 * config/lispdir.m4: Update from masters.
13085 * configure.ac: Bump to 2.52f.
13087 2001-11-02 Akim Demaille <akim@epita.fr>

13094 2001-11-01 Paul Eggert <eggert@twinsun.com>
13096 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13097 be invoked before _AS_LINENO_PREPARE.
13098 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13099 than character ranges.
13101 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13102 invoking AS_BASENAME. Set the locale variables to 'C' if
13103 possible, as POSIX requires this to get the traditional
13105 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13107 2001-10-31 Paul Eggert <eggert@twinsun.com>
13109 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13110 with {}, as that triggers a bug in Bash 2.05.
13112 (_AS_LINENO_PREPARE): Use Sed rather than
13113 Awk. Fix the sed prepass to work even if there are multiple
13114 instances of $LINENO on the same line. Do not substitute for
13115 other variables like $LINENOT. Do not check file dates; such a
13116 check is unreliable on sufficiently fast machines, and removing
13117 the check makes the code simpler and more reliable. Check for
13118 output and chmod failures.
13120 * doc/autoconf.texi (Special Shell Variables): Document
13123 2001-10-31 Akim Demaille <akim@epita.fr>

13128 2001-10-31 Akim Demaille <akim@epita.fr>
13130 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13131 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13132 provided, while it is optional.
13133 * configure.ac: Adjust.
13135 2001-10-26 Paul Eggert <eggert@twinsun.com>
13137 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13138 lib/Autom4te/Struct.pm:
13139 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13142 * doc/autoconf.texi (Special Shell Variables): Document some
13143 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13145 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13146 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13147 eval $LINENO is not portable in practice.
13149 2001-10-24 Akim Demaille <akim@epita.fr>
13151 * lib/Autom4te/General.pm (backname): New.
13153 2001-10-24 Akim Demaille <akim@epita.fr>
13155 * m4/: Remove, merged into...

13161 2.05's use of ANSI quoting in its `set' builtin.
13163 2001-10-22 Paul Eggert <eggert@twinsun.com>
13165 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13166 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13167 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13168 POSIX decided to standardize on the int flavor of strerror_r.
13169 Always do char* test, as there's no reason not to.
13170 Assign to a char* var, to catch strerror_r that returns int*.
13172 * doc/autoconf.texi (Particular Functions):
13173 Document the above changes. Also, document the fact that
13174 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13176 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13178 2001-10-20 Akim Demaille <akim@epita.fr>
13180 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

13183 2001-10-20 Akim Demaille <akim@epita.fr>
13185 * lib/Autom4te/General.pm (&update_file): If destination is
13186 unchanged, remove the source.
13187 (&up_to_date_p): Don't be verbose, be debug.
13188 * bin/autoreconf.in: No longer support --m4dir.
13189 (&autoreconf): Display the full path of the configure.ac we are
13191 Trace it only once.
13192 Be sure to honor --force with gettextize.
13193 Always run aclocal.
13194 * doc/autoconf.texi: Adjust.
13196 2001-10-20 Akim Demaille <akim@epita.fr>
13198 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13200 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13201 `intl' is already present, as it refuses unless --force.
13202 (&parse_args): Use -I, --include instead of the old Autoconf
13204 ($localdir, $autoconf_dir): Remove.
13206 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13208 2001-10-19 Jens Petersen <petersen@redhat.com>
13210 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

13229 configure.ac being studied.
13231 2001-10-18 Paul Eggert <eggert@twinsun.com>
13233 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13234 long, to work around a bug in the HP C compiler version HP92453-01
13237 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13238 (AS_BASENAME_EXPR): New macro.
13239 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13240 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13241 and fall back on 'sed' only if the other two fail. This makes
13242 AS_BASENAME act more like AS_DIRNAME.
13243 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13244 contains white space.
13245 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13246 Use AS_DIRNAME, since I think it's now DOS-friendly.
13247 * tests/m4sh.at (DIRNAME_TEST): New arg $3.

13259 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

13373 (AT_INIT): Replace AC_PLAIN_SCRIPT with AS_INIT invocation,
13374 include handle the m4_pattern_*, no longer push the

13385 CONFIG_SHELL defaults to a shell that supports LINENO if available.
13387 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
13388 shell does not support LINENO, and if CONFIG_SHELL is unset or
13389 empty, and if we can find a shell that does support LINENO,
13390 then set CONFIG_SHELL to that shell and then re-execute
13391 ourselves with CONFIG_SHELL.
13393 2001-10-05 Paul Eggert <eggert@twinsun.com>
13395 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
13396 doesn't exist. Remove *.tmp, as a .tmp file is created during the

13434 "source"; it's not portable. Remove confusing and
13435 somewhat-incorrect example involving "." and "/".
13437 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
13438 compatibility with POSIX shells.
13440 2001-10-02 Akim Demaille <akim@epita.fr>
13442 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
13443 instead of exec'ing to preserve $0 and $@.
13445 2001-10-01 Akim Demaille <akim@epita.fr>

13467 Don't use nested parenthesization. This patch was originally
13468 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,

13477 Check for `expr' arithmetic overflow, and for compilation failure,
13478 and invoke a new argument $4 if either is discovered.
13479 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13480 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

13514 * tests/fortran.at (GNU Fortran 77): there.
13515 * doc/autoconf.texi (autoconf Invocation): Fix the example:
13516 AC_TRY_RUN is about compilation, not shell commands.

13559 Don't compute at_srcdir nor at_top_srcdir.
13561 * tests/tools.at: Hence use top_srcdir.
13563 * tests/Makefile.am, tests/autoconf, tests/autoheader,

13647 Suggested by Jim Meyering.
13649 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

13698 * lib/autotest/general.m4: Englishoes.
13699 From Tim Van Holder and Alexey Mahotkin.
13701 2001-09-18 Paul Eggert <eggert@twinsun.com>
13703 * doc/autoconf.texi (Common Shell Constructs): New node,
13704 documenting AS_DIRNAME.
13705 (Limitations of Usual Tools): Refer to it when discussing dirname.
13706 Also, update discussion of POSIX standard to reflect latest draft.
13708 * lib/autoconf/c.m4:
13709 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
13711 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13712 Do not pass a first argument with leading '-'
13713 to expr, by parenthesizing initial integers that might be negative.
13715 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
13716 now merely checks whether it is an error to pass an argument
13719 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
13720 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
13721 whether it is a (compile-time) error to pass an argument to
13722 getpgrp. This simpler test supports the revised documentation,
13723 and is all that AC_FUNC_GETPGRP's users really need.
13725 2001-09-18 Akim Demaille <akim@epita.fr>
13727 * doc/autoconf.texi (Limitations of Make) <$<>: New.

13739 Add test for AS_BASENAME.
13740 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
13741 added test. It now correctly handles /1/2/3/, returning '3' not ''.
13742 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
13743 * tests/base.at: Fixed the expected responses. The old ones were
13745 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
13746 the documentation claims it should (and how it behaved in 2.13).
13748 2001-09-18 Akim Demaille <akim@epita.fr>
13750 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
13751 the AC_CONFIG_COMMANDS invocation.
13752 This also solves the name clash problems.

13754 * lib/m4sugar/Makefile.am (version.m4): Revamp.
13755 No longer to be shipped.
13756 (version.in): Remove.

13758 * lib/autoconf/status.m4: Adjust.
13759 Use `m4_PACKAGE_STRING'.
13760 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
13761 the only optional argument is the name of the test suite.
13762 Expect `package.m4' to define the package signature.
13763 * lib/autom4te.in (Autotest): Add `package.m4?'.
13764 * tests/Makefile.am (package.m4): New.
13765 * tests/suite.at: ifnames is a victim.
13767 2001-09-18 Akim Demaille <akim@epita.fr>
13769 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
13770 AC_LIBSOURCE, AC_CONFIG_FILES.
13771 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
13772 program version string doesn't match the package's.
13773 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

13784 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13785 Always include <stdio.h> and <stdlib.h>. Evaluate
13786 the expression in an extra function before these includes. Call
13787 fprintf "%d" only after ensuring the argument is of type 'int'.
13788 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
13790 2001-09-17 Paul Eggert <eggert@twinsun.com>
13792 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
13793 or CFLAGS=-O5. In that case, the linker has a relaxed view of
13794 fatal errors, and AC_CHECK_LIB causes it to include libraries even
13795 when they don't exist.
13797 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
13798 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
13801 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
13802 version with the version used by fileutils 4.1, except use
13803 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
13806 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
13808 2001-09-13 Akim Demaille <akim@epita.fr>

13846 2001-09-13 Akim Demaille <akim@epita.fr>
13848 * lib/autotest/general.m4 (AT_INIT): Create and remove
13849 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
13850 test suites can cohabit.
13852 2001-09-13 Akim Demaille <akim@epita.fr>
13854 * tests/mktests.sh: Don't output banners for empty test files.

13953 to avoid GCC warnings.
13956 2001-09-05 Akim Demaille <akim@epita.fr>

13960 2001-09-05 Akim Demaille <akim@epita.fr>
13962 Be ready to handle filenames as stupid as `dnl.at', for if even
13963 the maintainer is dumb enough to do that...
13965 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
13966 excellence in M4 quotation: consider `__file__' is active.
13968 And BTW, when invoking m4, pass the --include in the right order:
13971 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

13999 New, extracted from main.
14000 Use IO::File wherever possible.
14001 (input.m4): Be constant, use -I instead of hard coding $tmp.
14002 Therefore be a quoted heredoc.
14003 Don't invoke `_au_disable', since ac was not loaded, but just

14031 2001-08-31 Akim Demaille <akim@epita.fr>
14033 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
14034 (testsuite Scripts): There is no such thing as `atconfig.in'.
14035 And actually one diagram is missing: test suite runtime.
14037 2001-08-31 Akim Demaille <akim@epita.fr>
14039 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
14042 2001-08-31 Akim Demaille <akim@epita.fr>
14044 * bin/autoupdate.in (@include): `installcheck' revealed the path
14045 to m4sugar was lacking!
14047 2001-08-31 Akim Demaille <akim@epita.fr>
14049 * man/Makefile.am (.x.1): We really have to pass
14050 autom4te_perllibdir.

14060 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
14061 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.

14105 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14106 `autoheader: `config.hin' is created'.
14107 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14109 2001-08-31 Akim Demaille <akim@epita.fr>
14111 * bin/autoheader.in: Rewrite in Perl.

14117 Map --localdir, --autoconf-dir onto it.
14118 Forward autom4te's options instead of interpreting them.

14120 There is no such envvar since the inception of autom4te.cfg.
14121 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14122 * bin/autoupdate.in: Adjust, and perform more control.

14124 * tests/autoconf: Dittowise.
14126 2001-08-31 Akim Demaille <akim@epita.fr>

14142 * lib/Autom4te/General.pm (&find_peer): Remove.
14143 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14144 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14145 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14146 find the executables for it.
14147 * tests/Makefile.am: Major cleanup. Too lazy to document...
14148 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14150 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14151 indeed related to running the test suite, while passing
14152 --autoconf-dir and others is related to running non installed
14153 Autoconf executables. So don't do that, leave it to...

14155 * tests/autoscan: New.
14156 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

14173 Suggested by Paul Eggert.
14175 2001-08-29 Akim Demaille <akim@epita.fr>
14177 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
14178 download in a tmp dir.
14180 2001-08-29 Akim Demaille <akim@epita.fr>
14182 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

14352 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
14353 the name of the directory they're in, instead of the filename,

14582 * doc/autoconf.texi: Work around Texinfo buglets.
14583 (Transformation Rules): One example is enough, users are expected

14642 autom4te.cache (it's a directory, not a file.
14643 * Makefile.am: Ditto (but maintainer-clean-local).
14645 2001-08-15 Akim Demaille <akim@epita.fr>
14647 * bin/autom4te.in (@m4_warning): New.
14648 (&handle_m4): Use it.
14649 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

14658 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
14660 2001-08-13 Akim Demaille <akim@epita.fr>

14719 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
14721 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
14722 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
14723 * doc/autoconf.texi (C Compiler Characteristics): Update
14724 documentation for AC_C_BIGENDIAN.
14726 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
14728 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
14729 magic values from an object file when cross-compiling.

14732 2001-08-10 Akim Demaille <akim@epita.fr>
14734 * bin/autom4te.in (&handle_output): Don't use `grep' with side
14736 Suggested by Russ Allbery.
14738 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
14740 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
14741 current $prefix to the sub-configures.
14743 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
14745 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable

14750 * bin/autom4te.in ($icache): Load it only if older than autom4te.
14752 2001-08-07 Akim Demaille <akim@epita.fr>
14754 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
14756 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
14757 No need to remove the files before and after the each test, before
14758 each test and at the end of the suite is enough.
14759 Display only the children `times', not the shell's.
14760 If the test failed or was skipped, at-times is not available.
14762 2001-08-07 Akim Demaille <akim@epita.fr>
14764 Always produce testsuite.log, including when there are no
14765 failures. This helps getting information on skipped tests, and
14766 duration of the tests. Err, implement the latter btw.
14768 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
14769 Dump information on the first run of each test.
14770 (AT_CLEANUP): Create `at-times' containing the duration of the
14773 2001-08-07 Akim Demaille <akim@epita.fr>
14775 The use of `dumpstat' revealed that `len' was used although it
14776 should not. m4_text_wrap was using it, but in the Autoconf world
14777 where it is legal. Hence (i) test M4sh in its own world, not
14778 Autoconf's, and (ii), ahem, fix the bug :)
14780 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
14781 does not like `' instead of [].
14782 (AT_INIT): Forbid `^_?AT_'.
14783 And don't output such tokens.
14784 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
14785 `script.as', and `autom4te.cache'.
14786 Remove `empty' and `macro' which are no longer used.
14787 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
14788 * tests/m4sugar.at: Use it.

14791 2001-08-07 Akim Demaille <akim@epita.fr>

14797 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.

14808 2001-08-04 Akim Demaille <akim@epita.fr>
14810 Don't rely on M4sugar outputting the patterns in files, since we
14811 might process the output _without_ running m4, hence without these
14814 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
14815 * bin/autom4te.in (@Request::includes): Remove, unused.
14816 (@Request::source): Rename as...
14817 (@Request::input): this.
14818 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
