550 Pull in recent maintainer improvements from coreutils.
551 * GNUmakefile (_is-dist-target): 'make distclean' should not

593 that preceeds @dots. Improve wording.
594 (Text processing Macros): Drop `1' suffix from metasyntax variable
595 name that preceeds @dots.
596 (Number processing Macros): Drop `1' suffix from metasyntax

599 Suggested by Ralf Wildenhues.
601 2008-03-02 Jim Meyering <meyering@redhat.com>
603 Don't infloop upon "make dist".
604 * GNUmakefile: Merge from coreutils.
605 * Makefile.am (dist-hook): Inject .tarball-version into tarball,
607 * configure.ac (AC_INIT): Use .tarball-version, not .version.

617 Actually test that @configure_input@ is expanded correctly.
618 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
619 Actually check generated file contents for the name of the
620 generated file, using AC_PROG_FGREP and $FGREP.
622 2008-03-01 Benoit Sigoure <tsuna@lrde.epita.fr>

628 (autotools and whitespace in file names): Use them.
629 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
630 Cover more potentially problemtic file names. Use the new
633 Properly handle funny file names for headers in config.status.
634 The test suite did not cover this bug because the code was not
635 quoting properly the arguments of `rm -f' (which "fails" silently)
636 as well as the arguments of `diff' (whose output was redirected to
637 /dev/null so we couldn't see its error message).
638 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
639 file names passed to `rm' and `diff'.
640 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

743 Document grep peculiarity.
744 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Document
745 BSD behavior on binary input.
747 Minor testsuite improvements.
748 * lib/autotest/general.m4 (AT_INIT) <PREPARE_TESTS>: Use fewer
749 forks when sanitizing PATH. Always output machine information,
750 not just when atconfig was located.
752 Add 'testsuite -C dir'.
753 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
755 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
757 <DEFAULTS>: Delay computation of variables based on $at_dir...
758 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
759 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
760 <PARSE_ARGS>: Parse new option.

777 * doc/autoconf.texi (Particular Programs): Do not mention the
778 Autoconf version in which the AC_PROG_INSTALL change was done.
779 Suggested by Paul Eggert.
781 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
783 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
784 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
785 mode, we change to the source directory, also set $ac_pwd so we
786 do not go back to the build tree for the next config subdir.

788 config subdirs on the top level.

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

869 * tests/torture.at (Substitute a 2000-byte string): Drop
870 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
871 (Substitute a newline, datarootdir workaround): Likewise.
872 (Define a newline): Adjust for linenumber changes in configure.ac.
873 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
875 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
876 if `pwd` contains whitespace.
878 Quote $abs_top_srcdir in tests.
879 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
880 * tests/tools.at (Syntax of the shell scripts): Likewise.
882 * tests/m4sh.at (LINENO): Quote $0.
884 Fix testsuite program wrapper for whitespace in `pwd`.
885 The problem here is that the usual mantra is that command
886 variables can contain arguments, thus we cannot just escape
887 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
888 $top_builddir/tests directory early in $PATH, so that the
889 wrappers are found by their plain name.
890 * tests/wrapper.as: Put $testdir early in $PATH.
891 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
893 Proper config.status --file/--header and $srcdir escaping.
894 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
895 characters in $ac_file_inputs.
896 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs

901 Fix Autotest for whitespace in `pwd`.
902 * lib/autotest/general.m4 (AT_INIT)
903 <at_func_create_debugging_script, Driver Loop>:
905 * tests/autotest.at (whitespace in absolute testdir): New test.
907 * lib/autom4te.in: Quote @datadir@.
909 Proper file name escaping in Autoconf programs and Perl modules.
910 This includes escaping of characters special to the shell
911 as well as special to Perl, e.g., leading `<' or `>'.
912 For example, when $file starts with `>', `open ">$file"'
913 wrongly tries to append to a different file.
914 * bin/autoconf.as: Fix quoting for autom4te options.
915 * lib/Autom4te/General.pm (shell_quote): New function, taken
916 from coreutils, written by Jim Meyering.
918 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote

922 * bin/autoupdate.in (main): Likewise.
923 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
924 * bin/ifnames.in: Likewise, XFile usage fixes.
925 * tests/tools.at (autom4te and whitespace in file names): Extend
926 test. Test twice, with special characters allowed on w32, and the
927 rest. Test leading and trailing whitespace, for `open_quote'.
928 (autotools and whitespace in file names): New, analogous test.
929 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
930 by Russ Allbery and Eric Blake.
933 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
934 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
935 * lib/Autom4te/FileUtils.pm (open_quote): New function.
936 (update_file, contents): Use it.
938 * Makefile.am (autom4te-update): Rewrite for git.
940 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

945 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
946 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
948 2007-12-04 Eric Blake <ebb9@byu.net>
950 Manually resync with gnulib, since 'make cvs-update' no longer works.
951 * build-aux/config.guess: New upstream version.
952 * build-aux/config.sub: Likewise.
954 When using older automake, don't downgrade build-aux/texinfo.tex.

960 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
961 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
962 #undef as this runs afoul of our new way of creating config.h.
963 Problem reported by Jim Meyering in
964 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

968 Fix autom4te for unusual characters in input file names.
969 * bin/autom4te.in (files_to_options): Quote active characters
971 * tests/tools.at (autom4te and white space in file names):
974 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
975 Document that Tru64 awk always splits $0.
977 2007-11-24 Stepan Kasal <kasal@ucw.cz>
979 * lib/autotest/general.m4 (AT_INIT): Do not extract the
980 `#AT_STOP_...' line at the end of each test.
982 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
984 * lib/autotest/general.m4 (AT_INIT): For awk line number
985 extraction script, ensure `$at_group' has a defined value
986 even for the empty set, and properly quote its usage inside
989 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
991 * doc/autoconf.texi (Shell Functions): New chapter. Document
992 IRIX sh $0 issue in functions, move content from ...
993 (Portable Shell): ... here.
994 (Shell Script Compiler): Note that shell functions are not
995 totally unportable any more.
997 2007-11-22 Stepan Kasal <kasal@ucw.cz>
998 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1000 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1001 extracting the line numbers of the last needed test.
1003 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1005 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1008 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1010 Fix IRIX testsuite debugging failures: $0 in functions.
1011 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1012 Do not use $0 inside a function, as IRIX sh will set that to the
1013 function name rather than the script invocation name.
1015 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1016 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1018 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1019 to extract test scripts.
1020 (AT_INIT): Extract and cache test script line numbers.
1022 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1024 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1025 subsequent fixups; the awk -> here-document conversion trashes
1026 performance too much with AIX sh.
1028 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1030 * tests/local.at: Do not test m4, perl with AT_TESTED.
1032 Diagnose and guard against write errors dealing with config.status.
1033 The general idea is this: all write failures from `configure'
1034 writing `config.status' are indicated by $ac_write_error, which
1035 is only checked at the end. This is safe because config.status
1036 code is not executed before the file is complete. Other write
1037 failures, be they inside config.status, or in sub shell/awk
1038 scripts spawned from configure or config.status, typically need
1039 earlier checking, as their results are used right afterwards.
1040 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1041 before writing config.status, check afterwards.
1042 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1043 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1044 Set `ac_write_error' for write failures to config.status. Barf
1045 upon write failures to temporary files.
1046 Adjust note about closing and reopening the here-document.
1047 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1048 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1049 reopening the here-document.
1050 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1051 Ensure `ac_write_error' does not escape into config.status.
1052 Also, add a couple of code paths not yet exercised in the test
1053 suite: a config file with input from stdin, and a config header
1055 Suggestion for catching write errors by Bruno Haible.
1057 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1059 Avoid error with Tru64 awk and testsuite lines with many words.
1060 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1061 reads the testsuite, set the field separator to an unusual value,

1073 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1075 AC_*_TOOL does not canonicalize the prefix
1076 * doc/autoconf.texi (Generic Programs): Do not say that
1077 the *_TOOL macros canonicalize, they simply use the `host_alias'.

1081 Diagnose write errors in config.status instantiations.
1082 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
1083 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
1085 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1086 Extend test to also check for some write error failures, using...
1087 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
1088 Report by Bruno Haible.
1091 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix

1097 Add witness macro for @top_build_prefix@ substitution.
1098 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
1099 (_AC_OUTPUT_FILE): Mention it here.
1101 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
1102 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1104 * lib/autotest/general.m4 (at_func_test): Remove.
1105 (AT_INIT): Pre-extract test groups into separate files.
1106 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
1107 Remove at-test-source files together with the $at_group_dir.
1108 * tests/autotest.at (Long test source lines): New test.
1110 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1112 Shell functions and variables may share a namespace.
1113 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
1116 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
1118 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
1121 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1123 * lib/autoconf/status.m4: Fix a couple of comment typos.
1125 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1127 2007-11-13 Jim Meyering <meyering@redhat.com>
1129 Clean up the rule to create "expr".
1130 * tests/Makefile.am (expr): Don't redirect directly to target.
1131 Redirect just once, not for each echo statement.
1132 Use $@, not literal "expr".
1134 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1136 Don't worry about preprocessor when testing long long.
1137 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1138 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1139 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1140 These no longer check for preprocessor flaws.
1141 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1142 Do not check for preprocessor flaws.
1144 2007-11-13 Jim Meyering <meyering@redhat.com>
1146 Adapt dependencies, now that a version change doesn't modify configure.ac
1147 * GNUmakefile: Remove "make clean" kludge.
1148 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1150 Don't redirect directly to target.
1151 Use $@, not literal "version.m4".
1153 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1155 * doc/autoconf.texi (Making testsuite Scripts): Document
1156 ":;{" shorthand as in previous patch.
1158 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1160 * doc/autoconf.texi (Limitations of Builtins): Document problem
1161 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1163 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1164 Use ":;{" shorthand.
1165 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1167 2007-11-12 Jim Meyering <meyering@redhat.com>
1169 Add more non-srcdir build support.
1170 * GNUmakefile (dummy): Split a long line.
1171 Add -v option to autoreconf invocation.
1173 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1174 * GNUmakefile (dummy): Remove INSTALL.
1176 Remove racy commands to build scripts in bin/ and tests/.
1177 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1178 are guaranteed to be built, remove the rules that tried to build
1179 them. Before, with a parallel build, these rules could lead to
1180 two processes writing tests/wrapper.in concurrently.
1182 Build in man/ only *after* building in bin/ and tests/.
1183 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1184 in both bin/ and tests/.
1186 Accommodate non-srcdir build-from-checkout.
1187 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1188 Use git's --git-dir=$srcdir/.git option.
1189 Add quotes, in case tarball_version_file contains shell meta-characters.
1190 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1191 * configure.ac: Pass "." to git-version-gen.
1193 Avoid spurious test failures due to version skew.
1194 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1196 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1198 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1199 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1200 Remove conftest.dSYM directory.
1201 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1202 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1203 Remove `conftest.*' recursively.
1204 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
1205 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1207 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
1209 Report and analysis by Jeff Squyres and Peter O'Gorman.
1211 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
1213 Fix typos in variable names.
1214 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
1216 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
1218 Document that $((expression)) is not portable.
1219 * doc/autoconf.texi (Shell Substitutions): Here.
1221 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1223 Ignore configure --help* errors due to LINENO-impaired shells.
1224 * tests/torture.at (Configuring subdirectories, Deep Package):
1225 In the --help* tests in read-only trees, make `.' temporarily
1226 writable again for the `stderr' file, and ignore errors due to
1227 the attempt to write configure.lineno.
1228 Report by Patrick Welche.
1230 2007-11-10 Jim Meyering <meyering@redhat.com>
1232 Generate package.m4 in build-dir, not srcdir.
1233 * tests/Makefile.am (package.m4): Adjust target.
1234 Don't redirect directly to $@.
1235 (CLEANFILES): Add package.m4.
1236 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1238 When running $(AUTOTEST), search "." before searching $(srcdir).
1240 Avoid a race condition that would make parallel "distclean" fail.
1241 * tests/Makefile.am (distclean-generic): Replace the default,
1242 automake-provided rule with an identical one, but with an additional
1243 dependency on distclean-local. Simply adding the dependency would
1244 cause automake not to emit the rule at all.
1245 * BUGS: Building with -jN works, now.
1247 Distribute git-version-gen.
1248 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1249 since GNUmakefile is distributed, and requires it for dist* rules.
1251 Remove two more generated files from version control.
1252 * INSTALL: Remove generated file.
1253 * lib/autoscan/autoscan.list: Remove generated file.
1255 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1257 * GNUmakefile (PATH): Remove stray apostrophes; they become
1258 part of PATH, which isn't wanted here.
1260 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1262 New config files output variable `top_build_prefix'.
1263 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1265 * doc/autoconf.texi (Preset Output Variables): Document it.
1267 Report by Bob Friesenhahn.
1269 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1270 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1271 function, to parametrize arithmetic with expr vs. the shell.
1272 Use it where possible.
1273 Suggestion by Benoit Sigoure.
1275 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1277 Adjust the documentation of autotest WRT atlocal.
1278 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1279 when using Automake, to write a rule to produce atlocal, since it's
1280 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1281 distributed, not atconfig.in.
1283 2007-11-04 Eric Blake <ebb9@byu.net>
1285 Update list information.
1286 * README: Mention new autoconf-commit list.
1287 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
1289 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1291 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
1293 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1295 * build-aux/.gitignore: Ignore mkinstalldirs.
1297 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1299 2007-11-03 Jim Meyering <meyering@redhat.com>
1301 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1302 * build-aux/git-version-gen: This syncs from coreutils.
1304 Adjust the build procedure so "make check" works reliably.
1305 * README-hacking: Include an extra step between "make" and
1306 "make check" to ensure that the latter passes.
1308 Use just-built tools, when possible.
1309 * GNUmakefile (PATH): Set and export here, ...
1310 (dummy): ... rather than here.
1312 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1313 and Andreas Schwab <schwab@suse.de>
1315 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
1318 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1320 * configure.ac (AC_PREREQ): Require version 2.60, for
1321 AC_PROG_SED, AC_PROG_GREP.
1323 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
1324 and Jim Meyering <meyering@redhat.com>
1325 and Andreas Schwab <schwab@suse.de>
1326 and Eric Blake <ebb9@byu.net>
1328 Document a bug in GNU Bash with compound commands and redirections.
1329 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
1330 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
1333 2007-11-03 Eric Blake <ebb9@byu.net>
1335 Support m4 1.4.5 in testsuite.
1336 * tests/torture.at (Define a newline): Exclude line numbers in
1338 Reported by Ralf Wildenhues.
1340 2007-11-03 Jim Meyering <meyering@redhat.com>
1342 Remove automake-provided files from version control.
1343 * build-aux/elisp-comp: Remove file.
1344 * build-aux/install-sh: Remove file.
1345 * build-aux/missing: Remove file.
1346 * build-aux/mdate-sh: Remove file.
1347 * build-aux/.gitignore: New file.
1348 Suggestion from Ralf Wildenhues.
1350 2007-11-03 Eric Blake <ebb9@byu.net>
1352 Adjust version comparison to account for git snapshot numbers.
1353 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
1354 component separator.
1355 * doc/autoconf.texi (Number processing Macros)
1356 <m4_version_compare>: Document this change.
1357 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
1359 2007-10-30 Bruno Haible <bruno@clisp.org>
1361 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1362 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1363 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1364 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1365 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1366 Suggested by Paul Eggert.
1368 2007-10-28 Jim Meyering <meyering@redhat.com>
1370 * README-hacking: Autoconf, Automake, and Perl are required to build.
1371 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1373 2007-10-28 Jim Meyering <meyering@redhat.com>
1375 README-hacking: Recommend running autoreconf -vi.
1376 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1377 so that we use just-built tools when they're available.
1378 Suggestions from Ralf Wildenhues.
1380 2007-10-28 Jim Meyering <meyering@redhat.com>
1382 Make inter-release --version output more useful.
1384 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1385 which indicates that it is built using the 19th change set
1386 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1387 is a prefix of the commit SHA1.
1388 * build-aux/git-version-gen: New file.
1389 * configure.ac: Run it to set the version.
1390 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1391 * Makefile.am (dist-hook): Arrange so that .version appears only
1392 in distribution tarballs, never in a checked-out repository.
1393 * .gitignore: Add .version here, too. Just in case.
1394 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1395 not configure.ac, now that the version number changes automatically.
1397 Ensure that $(VERSION) is up to date for dist-related targets.
1398 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1399 git-version-gen doesn't match $(VERSION), but only for dist targets.
1401 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1403 Fix `Deep Package' failure with a configure script early in PATH
1404 * tests/torture.at (Deep Package): Add `.' early in PATH.

1433 problem reported by Bruno Haible in
1434 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
1436 2007-10-22 Eric Blake <ebb9@byu.net>
1438 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
1441 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1443 Don't check for bug in HP-UX 11.00 cpp.
1444 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
1445 Use -1ull rather than -1u, since that causes problems with gnulib; see
1446 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
1448 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1464 escaping of backslash in here-documents.
1466 Fix `Deep Package' test failure on FreeBSD.

1468 unnecessarily. Do not try running `/bin/sh configure' with a
1469 configure script to be found in $PATH, if the shell does not do
1470 this resolution. Fixes test failure on FreeBSD.
1472 Fix config header generation with AIX awk.
1473 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
1474 script, use helper array D_is_set, as `" 0"' does not evaluate
1475 to true for AIX awk.
1477 2007-10-21 Eric Blake <ebb9@byu.net>

1512 * lib/autotest/general.m4 (BANNERS): New named diversion.
1513 (TESTS_END): Diversion no longer used.
1514 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
1515 shell function, which prints only as needed, using an associative
1516 array of banner text from a special diversion.
1517 <PARSE_ARGS_END>: No longer need awk to find banners.
1518 <TESTS>: Banners are no longer processed by main driver loop, so
1519 we no longer need case statement.
1520 (AT_BANNER): Rewrite to populate new diversion.
1521 (AT_SETUP): Each test invokes its own banner. No output is needed
1522 to the TESTS diversion.

2550 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp
2551 choice, since that's what we do with --enable-largefile etc.

2553 the parens work with Emacs.
2555 * doc/autoconf.texi (Generic Compiler Characteristics): Fix typo

2639 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
2641 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
2643 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that

2655 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
2656 for a.* when searching for executables, as this prevents users
2657 from having files like a.c. Problem reported by Ralf Wildenhues in:

2670 AC_CHECK_TYPE, AC_CHECK_TYPES.
2671 * doc/autoconf.texi (Generic types): C types must be type-names
2672 (the C terminology), not type-ids (the C++ term). C++ types
2673 must not be anonymous.
2674 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
2675 for C++; this drops support for anonymous struct and union types,
2676 which were problematic anyway.

2695 with objects too. Document the restrictions on its use.
2696 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
2697 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
2698 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
2699 works but the latter doesn't, then it's a valid type.
2700 This lets people use function types and so forth.
2701 For C++ there doesn't seem to be a simple solution, so leave it alone.
2702 (AC_CHECK_SIZEOF): Allow argument to be a variable.
2703 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
2704 AC_CHECK_TYPE; that wasn't documented or necessary.
2706 2007-04-11 Stepan Kasal <kasal@ucw.cz>
2708 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

2727 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
2729 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
2730 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
2731 default still has the problem. Problem reported by Bruce Korb.

2756 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
2757 nonstandard grep R.E. escape sequences.
2759 2007-03-17 Jim Meyering <jim@meyering.net>
2761 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
2762 (Limitations of Usual Tools): Also list \< and \>, and mention that
2763 HP-UX's grep, like the one from Solaris, does not support that syntax.
2765 2007-03-09 Stepan Kasal <kasal@ucw.cz>
2767 * doc/autoconf.texi (Specifying Names): `--host' does not
2768 change the build type.

2806 status of rm so we know when it failed.
2807 If cleaning of test dir failed before running the test, warn.
2808 Output the line separator in verbose mode before the warning
2809 to make clear the warning belongs to the following test.

2874 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
2875 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
2876 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
2877 substitution will still be done by the special code.

2901 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
2902 early on the reader side, drop stderr of the input to avoid
2903 `broken pipe' error output; this may happen even with shell
2904 builtin `echo' of some bash versions. Reports by Ian Macdonald
2905 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
2907 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2921 * doc/autoconf.texi (Signed Overflow Examples): Give more
2922 discussion about the allow_superuser_privileges example,
2923 and change it a bit to make things clearer.
2924 (Optimization and Wraparound): Clarify whether the compiler
2925 will generate an infinite loop for the example derived from
2926 Autoconf's mktime test.
2927 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
2928 Also, clarify unsigned multiplication overflow.
2930 2007-01-04 Eric Blake <ebb9@byu.net>
2932 * bin/Makefile.am (RELEASE_YEAR): New macro.
2933 (edit): Use it to supply correct copyright year to scripts.

2935 * bin/autoheader.in ($version): Likewise.
2936 * bin/autom4te.in ($version): Likewise.

2942 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
2944 * doc/autoconf.texi (Integer Overflow): Revised based on today's
2945 feedback. The most important changes document what happens when
2946 you convert an out-of-range value to a signed integer type, and
2947 say that (sum < a) != (b < 0) reliably detects overflow when sum =
2950 * doc/autoconf.texi (Integer Overflow): Greatly expand and
2951 rewrite, taking notions from the recent discussion on the gcc and
2952 autoconf mailing lists; please see
2953 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
2954 and follow the many links.
2955 (Integer Overflow Basics, Signed Overflow Examples):

2957 (Signed Integer Division): New sections.
2959 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
2961 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
2962 preprocessor macro arguments in traced name.
2963 * doc/autoconf.texi (Defining symbols): Document longstanding
2964 support for AC_DEFINE-ing macros with arguments, and document
2965 behavior when the same variable has multiple AC_DEFINEs.
2966 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
2967 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
2968 macros directly, giving much shorter and simpler code.
2970 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
2972 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
2973 space before "$ac_configure_args" to prevent a 'config.status
2974 --recheck' failure if ac_configure_args doesn't contain a leading
2975 space. This works around a problem with the XEmacs configure.ac,
2976 which uses the (undocumented) ac_configure_args variable
2977 inconsistently with Autoconf.
2979 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
2981 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
2982 Include <limits.h>, and use its INT_MAX to rewrite the
2983 j loop so that it does not overflow 'int'. Problem reported by
2985 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
2986 Play it safe by shifting left by 1 rather than multiplying by 2,
2987 as GCC is less likely to optimize this away when the value
2988 is signed (when it assumes overflow leads to undefined behavior).
2989 Also, don't assume time_t uses two's complement.
2991 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2993 * tests/torture.at (Substitute a 2000-byte string): Avoid using
2994 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
2995 dumps core on it. Report by Tim Rice.

3012 * doc/autoconf.texi (Option Checking): Renamed from
3013 (Configure Option Checking). Tighten up the wording a bit.
3014 (External Software, Package Options): Cross-reference to Option
3015 Checking, and use this to shorten our section.
3016 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3017 "$x" to test "x$foo" != x.
3018 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3019 Don't warn if $enable_option_checking is "no".
3020 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3021 ac_unrecognized_opts to the empty string.
3022 Don't echo the unrecognized opts, as this might mishandle
3023 backslashes or leading -.
3024 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3025 usage next to the other --disable-FEATURE options in the

3030 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):

3032 Print warning for unrecognized --with and --enable options
3033 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3034 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3035 Disable option checking when subdirs are configured.
3036 (AC_OUTPUT): If warnings are enabled, print warning about
3037 unrecognized --with and --enable options at the end of
3038 the configure output (as well as at the beginning).
3039 * doc/autoconf.texi (Option Checking): New node.
3040 Document new option warning functionality.
3042 2006-12-16 Eric Blake <ebb9@byu.net>
3044 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3045 * NEWS: Start news for current version.
3047 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3049 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3050 Define HAVE_GETMNTENT to 1, not to the empty string.
3051 Problem originally reported by Jochen Friedrich in
3052 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3054 This change prompted by a problem report by Andrey Simonenko in
3055 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3056 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3057 object-like macros only, in the traditional portable character
3059 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3060 Warn about attempts to define things that are not identifiers.
3061 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3062 awful hack that AC_DEFINEd macro names containing parentheses.
3064 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3066 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3067 too drastic, even if Texinfo in theory requires it for info mode.
3069 (config.status Invocation): Renamed back from Recreating a
3071 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3072 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3074 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3076 * NEWS: Version 2.61a.
3078 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3079 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3081 * NEWS: Document changes with echo and printf, and the lack
3082 of limits on the total size of multi-line values of substituted
3083 variables, and the AC_FUNC_FSEEKO fix.
3085 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3087 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3088 Writing configure.ac.
3089 (Autoconf Input Layout): Renamed from configure.ac Layout.
3090 (Recreating a Configuration): Renamed from config.status Invocation.
3091 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3092 (acconfig Header): Renamed from acconfig.h.
3093 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3094 (Writing Testsuites): Renamed from Writing testsuite.at.
3095 (Autom4te Cache): Renamed from autom4te.cache.
3097 * BUGS: Remove mention of VPATH problem, since it's now documented
3098 not to be a bug in the Autoconf build procedure itself, but rather
3099 a problem with the proprietary `make' programs.
3101 * doc/autoconf.texi (Build Directories): Add a cross reference
3104 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3105 * doc/standards.texi: Sync from gnulib.
3107 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3108 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3109 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3110 generated automatically.
3112 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3114 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3115 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3116 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3118 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3120 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3121 `CEOF$ac_eof' special marker, the awk script cannot contain a
3122 line matching `^CEOF', so this is not needed any more.
3123 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3124 special marker in the test.
3126 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3128 * tests/tools.at (autom4te preselections): Use `find -newer';
3129 remove one of the sleeps.
3131 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3132 more readable, using ...
3133 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3135 * doc/autoconf.texi (autoheader Invocation): Do not double-
3136 quote the parameter of `AH_BOTTOM' in the example.
3138 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3140 * doc/autoconf.texi (Configuration Headers): Remove the
3141 example with multiple input files.
3142 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3143 multiple input files.
3145 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3147 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3148 creating the awk substitution script, handle one input line at a
3149 time, so that the maximum length of a substituted (multi-line)
3150 value is not limited by the size of the sed pattern space.
3151 The trade-off is a slightly repetitive sed script.
3152 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3153 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3154 * tests/torture.at (Substitute a 2000-byte string): Increase the
3155 test with several long lines, they should not be caught by sed
3158 * tests/tools.at (autom4te preselections): New test, to flag
3159 entries missing from autom4te.cfg.
3160 Report by David Byron <dbyron@hheld.com>.
3162 * tests/torture.at (Substitute a 2000-byte string): Actually use
3163 AC_PROG_AWK, so the last change works as intended.
3164 (Substitute and define special characters): Likewise.
3165 (Substitute a newline): Likewise.
3167 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3168 instead of `awk' consistently.
3169 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3170 * tests/torture.at (Torturing config.status): Test both the
3171 result of AC_PROG_AWK and plain awk.
3172 (Substitute a 2000-byte string): Likewise.
3173 (Substitute and define special characters): Likewise.
3174 (Substitute a newline): Likewise.
3176 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3178 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3179 can be assigned to a function pointer. Problem reported by
3180 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3181 part of a patch by Ralf Wildenhues in that same bug report.
3183 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3185 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3186 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3188 2006-12-01 Eric Blake <ebb9@byu.net>
3190 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3191 cross-compiling from cygwin to mingw.
3192 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3193 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3194 to lib/autoconf/c.m4.
3196 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3198 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3199 string for more reliable failure. Wrap the entire test that
3200 causes the broken Solaris printf to dump core, in a subshell,
3201 so the segmentation fault message is reliably suppressed.
3202 Fix shell expansion errors by using /usr/ucb/echo always;
3203 avoid an error on systems without it by another subshell.
3204 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3205 subshell-$as_echo to `as_echo', for better error message.
3207 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3209 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3210 `BASH_SOURCE' contain a newline, set them to empty, as they may
3213 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3215 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3216 years and is too hard to maintain now. The last straw was
3217 reported by Jerker Baeck in
3218 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3219 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3220 * doc/autoconf.texi (Particular Functions): Move
3221 AC_FUNC_SETVBUF_REVERSED from here...
3222 (Obsolete Macros): ... to here. Say that it does nothing now.
3223 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3224 Turn into (almost) a no-op.
3226 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3228 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3229 These macros are obsolescent and new applications shouldn't need them.
3230 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3231 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3232 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3233 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3234 (AC_FUNC_VPRINTF): Likewise.
3235 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3236 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3237 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3239 * doc/autoconf.texi (Setting Output Variables): Mention that
3240 @VAR1@VAR2 has unspecified behavior. Problem reported by
3242 * NEWS: Mention this.
3244 * Makefile.am: Put only a single '#' into the copyright notice,
3245 so that it's also present in the output file. Standardize wording
3246 in makefile copyright notices to match GNU coding standards.
3247 * bin/Makefile.am: Likewise.
3248 * doc/Makefile.am: Likewise.
3249 * lib/Makefile.am: Likewise.

3255 * man/Makefile.am: Likewise.
3256 * tests/Makefile.am: Likewise.
3257 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
3260 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3262 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3263 in the sed script that mangles the awk script: delete up to the
3264 first exclamation mark only.
3265 * tests/torture.at (Substitute and define special characters):
3268 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3270 Rewrite config files generation: avoid quadratic growth in
3271 the number of substituted variables by using awk instead of sed
3272 for the bulk of the substitutions.
3273 * NEWS: Mention this.
3274 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3275 forbidden in the output (and thus input) file.
3276 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3277 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3278 generate just one large awk script for substitutions,
3279 eliminating much of the earlier complexity, while adding some
3280 new complexity. Only expand the substitution templates at
3281 configure time, for smaller configure script size. If
3282 _AC_SUBST_FILES are used, test 'awk' for working getline support
3283 at config.status time. If absent, interpolate through the
3284 shell. The awk script was written with much help
3285 from Paolo Bonzini and Paul Eggert.
3286 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3287 (_AC_SED_FRAG_NUM): Likewise.
3288 (_AC_SUBST_CMDS): Renamed from...
3289 (_AC_SED_CMDS): ...this.
3290 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3291 * tests/torture.at (Substitute a 2000-byte string): Also
3292 substitute a line with 1000 words, and a variable with several
3294 (Substitute and define special characters): Test awk special
3295 characters, and put substitution input strings `@foo@' in the
3296 output, to test that no recursion happens; test several other
3297 combinations from Paolo Bonzini.
3299 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3301 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3302 that replaced echo with AS_ECHO where this wasn't necessary.
3303 Problem reportd by Ralf Wildenhues.
3304 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3305 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3306 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3308 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3310 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3312 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3314 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3315 that traditional Awk lacks 3-arg "split". It has it.
3316 Mention that FS must be a single character, and a few other
3317 99-byte limits of traditional Awk.
3318 Mention that if (i in a) doesn't work with traditional Awk.
3320 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3322 * tests/autotest.at (BSx641-newline in command):
3323 (BS-BS-newline in command, BSx640-newline in command):
3324 (Newline-CODE-BS-newline in command):
3325 (Single-quote-BS-newline in command):
3326 (Single-quote-newline-BS-newline in command):
3327 Use printf '%s\n' instead of echo, for portability to hosts
3328 where echo interprets backslashes. This will break on hosts
3329 that lack printf, but for now let's assume all such hosts
3330 are dead (if not, we should get reports of test failures).
3332 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3334 'echo' has some portability problems, when given a first argument
3335 with a leading '-', or when given any argument containing '\'.
3336 Avoid using 'echo' in these cases.
3337 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
3338 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
3339 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3340 * lib/autotest/general.m4 (AT_INIT): Likewise.
3341 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
3342 argument might be unportable.
3343 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
3344 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
3345 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
3346 (_AC_FC_LIBRARY_LDFLAGS): Likewise.

3348 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
3349 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
3350 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
3351 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
3352 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
3353 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):

3360 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
3361 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3362 * bin/autoconf.as: Redo verbose flag implementation, as the old
3363 scheme wouldn't work with AS_ECHO.
3364 * lib/autotest/general.m4 (AT_INIT): Likewise.
3365 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3366 Don't use ECHO_T, since ECHO_N is now reliable.
3367 * lib/autotest/general.m4 (AT_INIT): Likewise.
3368 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3369 rather than using a here-document to put the script into a file.
3370 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3372 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3373 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3374 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3375 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3376 * lib/autotest/general.m4 (AT_SETUP): Likewise.
3377 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
3378 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3379 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3380 operand, as AS_ECHO requires. Avoid double file name expansion.
3381 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3382 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3383 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3384 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3385 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3386 Double-quote strings that would otherwise contain M4 comments.
3387 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3389 * configure.ac (AC_INIT): Bump to 2.61a.
3392 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3396 * configure.ac (AC_INIT): Bump to 2.61.
3399 * tests/autotest.at (Macro with backslash in a test title):
3400 Comment out for now, as this tests neither fails nor passes
3401 reliably. Problem reported by Ralf Wildenhues.
3403 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3405 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
3406 in previous change, which caused test failures.
3408 2006-11-16 Stepan Kasal <kasal@ucw.cz>
3410 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
3411 code for --enable, --disable, --with, and --without to...
3412 (_AC_INIT_PARSE_ENABLE): ... a new macro.
3413 * doc/autoconf.texi (Package Options):
3414 * NEWS: Document that AC_ARG_ENABLE allows dots, too.

3418 Import these changes from config via gnulib:
3420 2006-11-15 Ben Elliston <bje@gnu.org>
3422 From Josselin Mouette <joss@debian.org>:

3469 2006-11-13 Bruno Haible <bruno@clisp.org>
3471 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): For --with, --without
3472 options, transliterate also dots to underscores.

3484 and Joel E. Denny <jdenny@ces.clemson.edu>
3485 and Paul Eggert <eggert@cs.ucla.edu>
3487 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
3488 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
3491 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3493 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
3494 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
3495 Imported from a similar patch to gnulib by Bruno Haible.
3497 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

3526 Single-quote in a test title,
3527 Double-quote in a test title): Don't expect failure anymore.
3528 (Backslash in a test title): Put a non-whitespace character after the
3529 backslash so that Bourne shells might actually see it as an escape
3531 (Brackets in a test title,
3532 Pound in a test title,
3533 Comma in a test title,
3534 Quoted Macro in a test title,

3538 Macro with double-quote in a test title,
3539 Macro with backslash in a test title): New tests expected to fail.
3540 * tests/torture.at (#define header templates): M4-quote this title in
3541 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3542 The visible effect was a stray [] in the testsuite output.
3544 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3546 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3547 `trap ... 0' inside a function, for AIX sh.
3549 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3551 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3552 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3553 5363) simply issues a warning when dividing by zero at compile
3554 time. Problem reported by Elias Pipping.
3556 2006-10-26 Eric Blake <ebb9@byu.net>
3559 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3560 show effect on macros that expand with commas.

3588 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3589 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3590 reported by Nelson H. F. Beebe for Coreutils 6.4.
3592 * tests/tools.at (autoconf --trace: user macros): Remove test
3593 for tracing multiline macros, since m4 1.4.7a uses a different
3594 way to number lines. Problem reported by Ralf Wildenhues.

3624 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
3625 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

3670 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
3672 (Imported from Automake.)
3673 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3674 which incorrectly sets the mode of an existing destination
3675 directory. In some cases the unpatched install-sh could do the
3676 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3677 system. We hope this is rare in practice, but it's clearly worth
3678 fixing. Problem reported by Alex Unleashed in
3679 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3680 Also, don't bother to check for -m bugs unless we're using -m;
3681 suggested by Stepan Kasal.

3729 * doc/autoconf.texi (Autoheader Macros): Warn that the text
3730 added to the template can get mangled.
3732 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3734 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
3735 include the default headers, and redefine obstack_chunk_alloc
3736 and obstack_chunk_free. Fixes false failure with glibc.
3738 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
3740 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

3755 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
3757 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
3758 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
3759 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
3760 Use a better substitute, by inspecting the output of "ls"
3761 rather than just using ":".
3762 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
3763 rather than AS_EXECUTABLE_P, since we needn't worry about
3764 non-regular files here.
3766 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
3767 due to configuration hassles with this. See Tonya Underwood's report

3780 initialization which is not inherited through the environment
3781 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
3782 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

3791 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
3792 comment about ac_cpp_err; it was incorrect, and anyway
3793 ac_cpp_err is being removed below.
3794 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
3795 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
3796 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
3798 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
3799 with werror_flag and conftest.err and so forth. This is more
3800 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
3801 and anyway the user shouldn't normally want to see this gorp logged.
3802 Problem reported by Ralf Wildenhues.
3803 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
3804 empty, not 'no', since the rest of the code uses 'test -z'.

3808 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3809 Use a single call to AC_DO_TOKENS rather than multiple, for
3811 (_AC_LINK_IFELSE): Test that resulting file is executable.
3812 Problem reported by mwoehlke in
3813 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
3815 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
3816 than creating a file to use with test -x; this is much faster.
3818 2006-10-02 Bruno Haible <bruno@clisp.org>
3820 * lib/autom4te.in (Automake-preselections): Add
3821 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
3823 2006-09-27 Stepan Kasal <kasal@ucw.cz>
3825 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
3826 standard error, `experr' should be used, not `expout'.

3830 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

3832 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3833 Set cache var to 'unknown' (not 'no') if leaving the macro unset
3834 still doesn't let the program compile.
3835 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
3838 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
3839 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
3840 include it, without including anything else.
3841 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
3843 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

3860 values. Problem reported by Ralf Wildenhues.

4022 except the first two arguments are reversed.
4023 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.

4071 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
4073 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
4074 didn't work if some values were cached but not others. Test for
4075 broken lex libraries like native ia64-hp-hpux11.22; see
4076 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4077 work around the problem by preferring an empty LEXLIB to -lfl or
4078 -ll. Let the user set LEXLIB='' to indicate no library needed.
4080 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.

4205 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
4206 -Wundef -Werror". Problem reported by David Fang in

4230 problems with arg script text that doesn't end in newline, and

4233 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
4235 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

4267 less skeptical about "volatile", after discussion with
4268 Bruno Haible on bug-gnulib.
4269 (Limitations of Usual Tools): Warn about sed stripping
4270 leading white space from text. From Bruno Haible.

4279 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.

4282 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
4284 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

4308 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4309 more globally, since the 2006-06-30 patch didn't suffice. Problem
4310 reported by Keith Marshall. Also, don't bother with builddir2,
4311 since it shouldn't be needed any more.
4313 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
4315 * doc/autoconf.texi (Generic compiler characteristics):
4316 Document AC_COMPUTE_INT. Fix wrong statements on Default

4332 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4334 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4335 Require that long long int be at least 64 bits wide. C99 requires
4336 this and enough programs depend on it so we should check for it.
4337 Bruno Haible reports in
4338 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4339 that long long int is 32 bits wide with some nonstandard compilers.

4346 a local site configuration that doesn't use /usr/local.
4347 Problem reported by Keith Marshall in
4348 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4350 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4352 * doc/autoconf.texi: Be more consistent about using @acronym with
4353 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4354 quite right (it talked about "OSF/Tru64", even though the
4355 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4356 and it even mentioned "OSF 4"!) and at this point there's little
4357 reason to talk about OSF any more, since it died in 1994.
4358 (Specific Compiler Characteristics): Simplify example of
4359 negative-size array.
4360 (File Descriptors): Reorder to make the text flow better.
4361 Remove joke about "appreciate the various levels"; I didn't get it.
4362 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4363 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4364 (File Descriptors, Limitations of Usual Tools):
4365 Tone down the advice against renaming or removing open files.
4366 (Limitations of Usual Tools): Add a new section, on 'rm'.
4368 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4370 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4371 -lXt in LIBS, idea from Karsten Hopp; this was due since
4374 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4375 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4376 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4377 (which belong to Xt, not X itself). See Debian bug 327655.
4379 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4381 * configure.ac (AC_INIT): Bump to 2.60a.

4401 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4403 * doc/autoconf.texi (Changed Directory Variables): New node,
4404 to document the whole `datarootdir' business a bit better.
4406 * tests/torture.at (datarootdir workaround): Extend test.
4407 Prompted by report by Alexandre Julliard.
4409 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4411 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4412 when using default mode of IBM C 6 for AIX. Problem and two-line
4413 fix reported by Larry Jones.
4415 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4417 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4418 about literal '${datarootdir}' if a definition is found in the
4421 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4423 * NEWS: Use "M4" rather than "m4" when appropriate.
4424 Problem reported by Eric Blake.
4425 * doc/autoconf.texi: Likewise.
4426 Use @acronym around BSD, GCC, and GNU when appropriate.
4427 (Why GNU M4): Renamed from "Why GNU m4".
4428 (Redefined M4 Macros): Mention that Posix
4429 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4430 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4433 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4435 * bin/autom4te.in (handle_output): Do not forbid the empty
4437 * tests/tools.at (autoconf: the empty token): New test.
4439 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4441 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4442 calls, so that we do not care whether they are LIFO or FIFO;
4443 in the m4_wrap, do not check which diversion is the topmost
4444 one, just check that the stack is balanced at the end.
4445 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4446 base diversion forever--pop the previous diversion before
4447 opening the new one; consequently, remove the m4_wrap call.
4448 * lib/autotest/general.m4 (AT_INIT): Likewise.
4449 * tests/m4sugar.at: Do not use
4450 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
4452 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4453 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4455 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4456 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4457 Rework example of m4wrap token-pasting trouble so that it doesn't
4458 care whether it's LIFO or FIFO.
4459 Fix some "contrary to"s that are awkward in English.
4461 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4463 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4464 to `yes' instead of `int$1_t' if the type is found, for more
4465 consistent configure output (where $1 is the number of bits).
4466 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4467 Suggested by Bruno Haible.
4469 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4470 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4471 with system headers. Report by Bruno Haible.
4473 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4475 * config/config.guess, config/config.sub: Sync from upstream.
4477 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4478 in order to avoid picking up an older installed frozen m4sh.m4f.
4479 Besides an outdated shell startup, this could have been created
4480 by an earlier M4 version with incompatible frozen file format.
4482 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4484 * README: Recommend m4 1.4.4 instead of 1.4.3..
4485 * doc/autoconf.texi: Likewise.
4486 (Special Chars in Names): Say that $(.FOO) is portable, as
4487 suggested by Stepan Kasal.
4488 (Installation Directory Variables, Build Directories):
4489 (Automatic Remaking, Subdirectories, Fortran Compiler):
4490 (Making testsuite Scripts, Defining Directories):
4491 Quote variable usages better.
4492 (Making testsuite Scripts): Add clean-local rule to makefile
4493 snippet, by Eric Blake.
4494 (Installation Directory Variables): Fix table item font.
4495 Reword slightly to clarify. Generalize advice about
4496 not using special characters to include all file-related
4497 vars, not just VPATH.
4498 (Special Chars in Variables): Warn about special characters in
4500 (Assignments): Clarify default-value example as suggested by
4502 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4503 (Special Shell Variables): Note leading ./ or ../, as suggested
4505 (Limitations of Builtins): Under cd, warn about CDPATH.
4506 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4509 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4511 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4512 `@var', for texi2html.
4513 (Systemology): Some more word wrapping, for DVI output.
4514 (autom4te Invocation): The short option for `--melt' is `-M',
4517 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4519 * doc/autoconf.texi: More formatting and English tweaks,
4520 many suggested by Ralf Wildenhues.
4521 Reword to avoid "@code{...}'s" and the like, since it's ugly
4522 with Emacs info mode. discontents -> woes.
4523 Put a few "will"s back. time stamp -> timestamp.
4524 side-effect -> side effect.
4526 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4528 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4529 Warn about $@ not persisting. Problem reported by Julien Danjou in
4530 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4531 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4532 Mention other special chars, too.
4534 2006-06-14 Eric Blake <ebb9@byu.net>
4536 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4538 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4540 * doc/autoconf.texi: Some systematic minor improvements, as
4541 follows. Use "makefile" when talking about makefiles
4542 generally (which might be named "makefile" or "Makefile" or even
4543 "foo.mk"), "Makefile" when talking about a specific makefile
4544 called "Makefile". This unclutters the text from weird quotes
4545 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4546 values" rather than "@var{foo}s" and similar constructs containing
4547 "}s". Use "Make rules" rather than "Makefile rules". Minor
4548 English-language improvements. Change the prefix "sub-" to "sub"
4550 Put blank lines around examples more consistently.
4551 Avoid "rather" and "very" as intensifiers.
4552 Avoid "will" as an auxiliary.
4553 (Limitations of Make): Split this node into....
4554 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4555 (Leading _ in Macro Names, Backslash-Newline-Newline):
4556 (Backslash-Newline Comments, Long Lines in Makefiles):
4557 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4558 (obj/ and Make, make -k Status, VPATH and Make):
4559 (VPATH and Double-colon, $< in Explicit Rules):
4560 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4561 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4562 New nodes, resulting from splitup of Limitations of Make.
4563 All cross-references changed. Raise the top node from
4564 a section to a chapter, and all subnodes accordingly.
4565 Redo the introductory wording to match the new organization.
4566 (Installation Directory Variables): Use an example that is
4567 closer to what Autoconf actually does. Mention that VPATH's
4568 value should not contain metacharacters or white space.
4569 (Fortran Compiler): Fix a VPATH bug in an example.
4570 (Leading _ in Macro Names): Mention that this problem is no longer
4571 of practical concern.
4572 (VPATH and Make): Reword the advice to make it clearer
4573 that Autoconf and Automake support VPATH in non-GNU make, but
4574 many packages have bugs in this area.
4575 ($< in Explicit Rules): Refer to Build Directories rather
4576 than using a (non-VPATH-safe) example.
4577 (Automatic Rule Rewriting): Mention the sort of disaster that
4578 can ensue with Solaris-style rule rewriting with VPATH.
4580 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4582 * doc/install.texi (Compilers and Options): Weaken the
4583 suggestion to use GNU make for VPATH builds.
4585 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4586 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4588 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4589 in regular expression.
4591 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4593 * doc/autoconf.texi (Installation Directory Variables):
4594 Drop extra @samp from `@table @samp' item.
4595 (Limitations of Usual Tools): Comment fix.
4596 Do not nest @samp just to point to other table items.
4597 (Writing testsuite.at) <AT_CHECK>: The second argument to
4598 `@dvar' is already @samp'ed.
4599 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4600 do not use @var in the second argument.
4602 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4604 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4605 $as_shell.exe too. Problem reported by Andreas Buening in
4606 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4608 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4610 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4611 `unused variable' compiler warning, for `-Wall -Werror'.
4612 Reported by Jaap Haitsma in
4613 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4615 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4617 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4618 case the compiler dumps core. Problem reported for
4619 OpenServer 5.0.7 by Tim Rice in
4620 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
4621 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4624 2006-06-06 Tim Rice <tim@multitalents.net>.
4626 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4627 "ERROR" only shows up in "make check" output if there is an
4630 2006-06-06 Eric Blake <ebb9@byu.net>
4632 * tests/tools.at (automatically allowed tokens): Fix typo.
4634 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4636 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
4638 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
4639 typically overflows on x86 CPUs, even though the C standard
4642 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4644 * configure.ac (AC_INIT): Bump to 2.59e.
4647 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4651 * config/texinfo.tex: Sync from upstream.
4653 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4654 seen, invoke libtoolize with `--ltdl' argument.
4655 * lib/autom4te.in (Autoreconf-preselections): Adjust.
4657 Suggested by Eric Blake.
4659 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4661 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
4662 reported by Ralf Wildenhues.

4665 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4669 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4671 * doc/autoconf.texi: Modernize some of the references to Solaris.
4673 2006-06-05 Stepan Kasal <kasal@ucw.cz>
4675 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
4676 message issued by AC_REQUIRE.
4677 * tests/m4sugar.at: Check m4_require's error message.
4678 * tests/base.at: Check AC_REQUIRE's error message.
4679 * tests/local.at (AT_CHECK_M4): New macro, almost identical
4681 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
4683 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
4684 `expout' as the last parameter.
4685 * tests/tools.at: Adapt to the above change.
4687 2006-06-04 Stepan Kasal <kasal@ucw.cz>
4689 * doc/autoconf.texi (Limitations of Usual Tools): Correct
4690 information about race-free implementations of mkdir.
4692 2006-06-04 Eric Blake <ebb9@byu.net>

4697 * doc/autoconf.texi (autom4te Invocation): Likewise.
4699 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
4701 * NEWS: GNU make now recommended for VPATH builds.
4702 Mention that some macros are now documented to be obsolescent.
4703 * doc/autoconf.texi:
4704 Prefer "current" to "modern" to describe
4705 currently-used (albeit perhaps old-fashioned) hosts.
4706 Mention which ancient features no longer need to be worried about.
4707 setgid -> set-group-ID
4708 setuid -> set-user-ID (these are the Posix terms)
4709 Fix some misuses of "only".
4710 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
4711 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
4712 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

4719 Mention that these macros are obsolescent.
4720 (Installation Directory Variables): shall -> should
4721 (File Descriptors): Mention that 0, 1, 2 might get reopened.
4722 Mention that it's now safe to use 3 and 4.
4723 (Limitations of Usual Tools): cp -r is now specified by Posix.
4724 Omit longwinded and obsolescent discussion of cp -f.
4725 Modernize discussion of expr, ls.
4726 (Limitations of Make): Modernize discussion of VPATH builds.
4727 Mention $? as a workaround in some cases.
4728 * doc/install.texi (Basic Installation):
4729 Mention "./configure; make; make install" first. Be more
4730 specific about why this file is generic. Remove unnecessary
4731 parens. Remove misleading "only". Remove obsolete advice
4732 about csh. Don't say "configure" takes awhile; say it
4733 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
4734 and CC=c99 rather than CC=c89, as these are blessed by current
4735 Posix. Recommend GNU make if doing a VPATH build.
4737 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
4739 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
4740 examples involving shell prompts.
4742 2006-06-02 Stepan Kasal <kasal@ucw.cz>
4743 and Paul Eggert <eggert@cs.ucla.edu>
4745 * doc/autoconf.texi (Here-Documents): Add details about the
4746 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
4747 use "here-documents" instead of "here documents".
4749 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4755 * doc/autoconf.texi (File System Conventions): Warn about ":"
4756 anywhere in directory names.
4758 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
4760 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
4761 about quoting the case statement, just in case.
4762 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
4763 was fixed in ksh93g; reported by Ralf Wildenhues.

4777 argument with leading hyphen. Problem reported by Paul Eggert.
4779 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4781 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
4782 about quoting ac_try: quote all of it, if any of it seems suspicious.
4783 This means we don't have to worry about ${ or sed any more.
4784 Also, double-quote the case statement, to work around misuses via
4785 underquoting as reported by Ralf Wildenhues in
4786 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
4787 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
4788 undocumented and dangerous macro.
4789 Problem reported by Ralf Wildenhues in
4790 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.

4798 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4800 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
4801 since evidently some packages rely on the old, broken behavior.
4802 Problem reported by Ralf Wildenhues in
4803 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
4804 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
4805 pre-2006-05-26 definitions, but leave in the comments that
4806 these macros are dangerous and should not be used.
4807 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
4808 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
4809 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
4810 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
4811 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
4813 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4815 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
4816 the use of 'tr', since this is our only use of 'tr'.
4818 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4819 and Paul Eggert <eggert@cs.ucla.edu>
4821 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
4822 Don't assume 'grep' works on long lines, since AIX grep doesn't.
4824 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4826 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
4827 the output file in the `${datarootdir}' test.
4829 2005-05-28 Stepan Kasal <kasal@ucw.cz>
4830 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4832 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
4833 mention of `datarootdir' in the input file(s), but literal
4834 `${datarootdir}' in the output file, and we haven't warned yet,
4835 then warn as well: the user may have (erroneously) used
4836 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
4837 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
4838 * tests/torture.at (datarootdir workaround): Extend this test.
4841 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4842 and Paul Eggert <eggert@cs.ucla.edu>
4844 * doc/autoconf.texi (autoheader Invocation): The first argument to
4845 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
4846 alternatives and clear up the language a bit.
4848 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
4850 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
4851 ac_config_guess, ac_config_sub, ac_configure.
4852 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4853 Fix typo that prevented an unnecessary space from being removed.
4854 Problems reported by Ralf Wildenhues in:
4855 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
4857 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4859 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
4860 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
4861 Don't use the term "thread-safe" to talk about mkdir race
4862 conditions, since the problem is more a process than a thread
4863 issue. Problem reported by Stepan Kasal in:
4864 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
4865 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
4866 the test for 'install' more closely. Look at MKDIR_P first.
4867 Look in the PATH, and at /opt/sfw/bin.
4868 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
4869 Don't bother to try mkdir -p, since we already check mkdir --version;
4870 just look at the version number. (There's no easy way to check
4871 for race-free implementations.)
4872 * tests/tools.at (autoconf: subdirectories): Adjust to above
4873 changes, since MKDIR_P now might end in "/mkdir -p".
4875 * doc/autoconf.texi (autoheader Invocation): Mention that the
4876 first arg of AC_DEFINE_UNQUOTED must be a literal.
4877 Problem reported by Ben Pfaff in
4878 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
4880 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
4881 * doc/autoconf.texi (Special Chars in Variables): New section.
4882 (Preset Output Variables): Warn about special chars in CPPFLAGS.
4883 (Installation Directory Variables): Quote $(datadir) better.
4884 (Limitations of Builtins): Describe some of eval's trickiness.
4886 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
4887 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
4888 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
4889 in front of every arg, not just trailing args. Quote apostrophes.
4890 (_AC_EVAL_ECHO): New macro.
4891 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
4892 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
4894 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
4895 exposed by quoting of eval argument. Put the command on line line
4897 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
4898 (_AC_PATH_X, AC_PATH_X): Quote more safely.
4899 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
4900 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
4901 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
4902 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
4903 Use eval more safely.
4904 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
4905 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
4907 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
4908 lines, exposed by quoting of eval argument.
4910 2006-05-26 Stepan Kasal <kasal@ucw.cz>
4911 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4913 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
4914 initialization of `ac_cv_exeext', do not override it if it was
4915 already set, unless it was set to `no', for compatibility with
4916 Autoconf-2.13, and comment this.
4917 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
4918 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
4919 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
4920 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
4921 Document that this test may be overridden by setting
4924 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4926 Revert these two patches:
4928 2006-04-06 Eric Blake <ebb9@byu.net>
4929 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4930 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4933 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4934 Clean up _AC_COMPILER_EXEEXT* macros.
4935 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4936 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4937 ac_file to the name of the default output file and call
4938 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4939 initial `rm' of the candidate files...
4940 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4941 the same list in subsequent `rm' calls, and for the temporary
4942 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4943 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4944 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4945 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4946 no longer needed) by libtool. Make it a cache check.
4947 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4948 copied here by mistake.
4949 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4950 _AC_COMPILER_EXEEXT.
4951 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
4952 _AC_COMPILER_OBJEXT directly.
4953 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4955 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4957 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
4958 Fix description of how the buggy `sed' works.
4960 2006-05-25 Noah Misch <noah@cs.caltech.edu>
4964 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
4965 ENOLCK. Only mention `make -j' when applicable. Only raise
4966 fatal errors when `make -j' is involved. Improve error message.
4968 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4970 * doc/autoconf.texi (Here-Documents): We now know more about
4971 the variable expansion in here documents bug.
4972 Thanks to Tim Rice and Stepan Kasal.
4974 * doc/autoconf.texi (Making testsuite Scripts): Add an example
4975 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
4977 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4979 * tests/autotest.at (Multiline command from M4 expansion):
4980 No failure to be expected if the shell quotes newlines in
4981 commands in the `set -x' output. Report by Tim Rice.
4984 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4986 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
4987 expansion in the here-documents used by config.status, as that
4988 runs afoul of the Korn shell version M-12/28/93d bug described in
4989 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
4990 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
4991 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
4993 2006-05-23 Jim Meyering <jim@meyering.net>
4995 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
4996 Fix typo introduced with 2006-04-02 change. It reversed the sense
4999 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5001 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5002 ac_dB slightly, to save bytes in the script.
5003 Max out at 50 lines, rather than 96; this is more likely
5004 (though not guaranteed) to avoid obscure 'sed' failures.
5006 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5008 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5009 `tr -d -' as bad option argument. Work around this by deleting
5010 an unrelated character.
5011 Report by Tim Rice <tim@multitalents.net>.
5013 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5014 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5015 Stepan Kasal <kasal@ucw.cz>
5017 * doc/autoconf.texi (Particular Programs): Do not promise that
5018 we always prefer the GNU version of the program, and that we
5019 search according to PATH; both rules can have exceptions.
5020 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5021 AC_PROG_SED. Move descriptions of limitations
5022 to the Limitations of Usual Tools section.
5023 (Limitations of Usual Tools) <sed>: Mention script length
5024 limitations with Solaris /usr/ucb/sed.
5025 <grep>: Fix wording for empty alternative. Mention that -c and
5026 -l should not be combined, and that -E and -F should not be
5029 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5030 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5032 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5033 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5035 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5037 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5038 AC_DEFINE is now passed to m4_pattern_allow.
5039 * NEWS: Mention that; likewise for AC_SUBST.
5040 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5041 the parameter to m4_pattern_allow.
5042 * tests/tools.at: Add a check for that.
5044 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5046 * lib/autoconf/status.m4: Fix typos.
5048 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5050 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5051 only the files that this macro generates.
5053 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5055 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5056 the HP-UX sed limitation of 99 commands, labels do not count.
5057 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5059 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5061 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5063 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5064 Import the following fix from coreutils:
5066 2006-01-13 Jim Meyering <jim@meyering.net>
5068 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5069 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5070 not double-quote uses of that variable, to accommodate the rare
5071 case in which getmntent is available in none of the libraries
5072 checked. This happens at least on FreeBSD 5.0.
5074 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5076 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5077 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5078 some other programs unwisely rely on these undocumented vars.
5079 But put in warning comments about them.
5080 Problem reported by Ralf Wildenhues in
5081 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5082 * NEWS: Document that these variables are intended to go away.
5084 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5086 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5087 and set the language to C++ (analogous to the equivalent Fortran
5090 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5091 * doc/autoconf.texi (C++ Compiler): Document it.
5092 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5095 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5097 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5098 that caused config.status to generate 100-command sed scripts; the
5099 portable limit is 99.
5101 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5103 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5104 variable `ac_d' instead of `d' to avoid infringing namespace.
5105 Report by Ralf Menzel.
5107 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5109 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5110 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5111 * tests/tools.at (autoconf: subdirectories): New test, taken from
5112 the corresponding problem report by Ralf Wildenhues in:
5113 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5115 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5116 Quote some uses of shell variables if they might suffer unexpected
5117 globbing. This doesn't fix all instances of quoting problems that
5118 I found, just the easy ones that look safe.
5119 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5120 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5121 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5122 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5123 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5124 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5125 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5127 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5128 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5130 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5132 * bin/autoreconf.in ($help): Reword according to the manual.
5133 Suggested by Olly Betts.
5135 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5136 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5138 * bin/autoreconf.in: Pass the directory argument to
5139 `require_configure_ac'. Fix comment.
5140 * tests/torture.at (Configuring subdirectories): Expose this.
5141 Reported by Olly Betts.
5143 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5145 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5146 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5147 Automake as follows:
5149 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5150 `$configure_in' instead of `configure.in', to preserve
5151 directory component.
5153 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5155 * config/config.guess, config/config.sub, config/texinfo.tex,
5156 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5158 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5160 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5161 test for C99 conformance; (bool) 0.5 is an integer constant
5162 expression, but (bool) -0.5 is not. Problem reported by Fedor
5163 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5165 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5167 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5168 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5169 Warn about obsolete install-sh files. Remove stray sentence
5170 fragment and fix cross reference.
5171 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5172 install -d; this undoes the 2006-05-10 change.
5173 (MKDIR_P): Mark with AN_MAKEVAR.
5174 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5175 that we don't require $INSTALL to be thread-safe. Move comments
5176 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5177 of AC_PROG_INSTALL. Output a message saying that we're checking
5178 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5179 MKDIR_P instead of AC_SUBST.
5180 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5181 Special magic for MKDIR_P, too.
5182 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5184 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5186 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5188 Sync from Automake, as follows:
5190 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5191 * config/install-sh: Initialize IFS, so field splitting isn't
5193 * config/mkinstalldirs: Likewise.
5194 * config/missing: Remove superfluous quotes. Replace all uses of
5195 `[' by `test', for consistency, and for..
5196 * config/missing (sed_minuso, sed_output): New variables.
5197 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5198 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5199 Fixes `missing' to detect `--output' for help2man. Fixes
5200 PR automake/483. Report by Dennis J. Linse.
5201 (autom4te): Document in `missing --help'.
5203 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5205 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5206 * config/install-sh: Don't use 'path' to talk about file names,
5207 as per GNU coding standards. Close a race condition reported by Ralf
5208 Wildenhues and Stepan Kasal. There is still a race condition
5209 on hosts that predate Posix 1003.1-1992, but we can't help this.
5210 Don't mishandle weird characters like space on pre-Posix hosts.
5211 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5212 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5213 AC_PROG_MKDIR_P from AS_MKDIR_P.
5214 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5215 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5216 earlier editions are not (including Automake 1.8.3).
5217 Do not suggest mkinstalldirs for thread-safety.
5218 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5219 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5220 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5221 presence of special characters and race conditions.
5222 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5223 in Autoconf's name space.
5225 2006-05-10 Bruno Haible <bruno@clisp.org>
5226 and Paul Eggert <eggert@cs.ucla.edu>
5228 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5229 from Automake with minor changes.
5230 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5232 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5234 * config/install-sh: Update to Automake CVS version, as follows:
5235 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5236 * lib/install-sh: Simplify the expr implementation of dirname.
5237 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5238 * lib/install-sh: Handle --, and diagnose unknown options.
5240 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5242 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5243 `./autom4te' to create `./testsuite', since the `all' target
5244 will ensure its presence, but `installcheck' should not create
5245 the uninstalled wrappers.
5247 * tests/torture.at (Unusual Automake input files): Skip if we
5248 detect automake < 1.8.
5250 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5252 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5253 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5254 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5257 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5259 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5260 munge (multiple) white space and other oddities.
5261 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5262 single quotes in variable assignment.
5263 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5264 and similar failures by adding multiple spaces, tabs, and other
5266 Report and different test suggested by Francesco Romani
5267 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5269 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5270 single quotes, we only need to search for single quotes; this
5271 both simplifies the search pattern, and makes us less
5272 susceptible to `echo' variations for arguments not containing
5274 (_AC_ARG_VAR_VALIDATE): Likewise.
5276 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5278 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5279 `$*' and IFS concatenation issue with traditional shells and
5280 bash-2.04. Report by Seanster@Seanster.com.
5282 2006-05-03 Bruno Haible <bruno@clisp.org>
5284 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5285 precisely which Mac OS X versions have the od problem.
5287 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5289 * doc/autoconf.texi: Use @option systematically.
5291 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5292 and Bruno Haible <bruno@clisp.org>
5294 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5296 (Integer Overflow): Mention the special case of integer division
5299 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5301 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5302 traditional shells like the Solaris one that do not use the

5358 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5360 * bin/autoconf.as (me): Replace by as_me.
5362 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5364 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5365 since as_me isn't set yet.
5367 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5369 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5370 a few minor bugs in this area.
5372 * doc/autoconf.texi (Programming in M4sh): Comment out the
5373 documentation of AS_BASENAME, for now.
5374 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5375 (Limitations of Builtins) <basename>: Do not refer to
5377 * bin/autoconf.as (me): Don't use AS_BASENAME.
5378 (dir): Remove the unused variable.

5393 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5395 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5396 of "run time" and "run-time" changed to "runtime", for consistency.

5403 with more accuracy and detail.
5405 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5407 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5408 Archive is not officially `GNU' any more. Update URL.
5409 (Defining Directories): Likewise
5410 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5412 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5414 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5415 newline from the `trap' code to finish `config.log'; the NetBSD
5416 /bin/sh resets the exit status after an empty command, as
5417 documented in doc/autoconf.texi.
5418 Reported by Dalibor Topic <robilad@kaffe.org>.
5420 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5422 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5423 Suggested by Bruno Haible.
5425 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5427 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5428 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5429 Instead, just list the shells that we know work.
5430 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5431 changed. Be more cautious about the _cv_ variable.
5432 * tests/tools.at (Syntax of the shell scripts): Check the
5433 _cv_ variable once, at first, to avoid an internal autoconf error
5434 when sh -n does not work.
5436 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5438 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5440 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5442 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5443 use ">&-" since we're only 99.999% sure that this is portable,
5444 and since the MinGW bug is fixed in a different way.
5445 * lib/autotest/general.m4 (AT_INIT): Likewise.
5447 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5449 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5450 before opening config.log, to avoid hitting a bug on MinGW.
5452 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5454 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5455 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5456 This works around a MinGW bug reported by Eric Paire.
5457 Make sure that all writes to the log file append to it,
5458 rather than possibly losing data.
5459 * lib/autotest/general.m4 (AT_INIT): Likewise.
5461 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5463 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5466 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5470 * configure.ac (AC_INIT): Bump to 2.59d.
5472 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5476 * Makefile.maint (news-date-check): Do not require a leading `*'
5477 before the release date in NEWS.
5479 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5480 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5482 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5483 the instantiated file do not contain the string 'datarootdir'
5484 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5485 @mandir@, replace the reference '${datarootdir}' by the value.
5486 * tests/torture.at (datarootdir workaround): New test.
5487 * NEWS: Advertise this temporary fixup.
5488 Based on a patch by Bruno Haible, reported and analyzed by
5489 Paul Eggert and Noah Misch.
5491 2006-04-12 Eric Blake <ebb9@byu.net>
5493 * tests/autotest.at (Debugging a failed test): Fix comment.
5495 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5497 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5498 all the changes since 2006-04-07.
5500 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5502 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5503 succeeded, but `ln -s file dir' failed, take care to remove the
5504 leftover target before the next test, to prevent its spurious
5505 failure; also make sure `ln file dir' works before selecting it.
5506 Thanks to Keith Marshall for pointing this out.
5509 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5510 assignments in `at_debug_args', so that we put them correctly
5511 in the `run' script.
5512 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5513 Reported by Eric Blake.
5515 2006-04-11 Eric Blake <ebb9@byu.net>
5517 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5518 top-level tests after micro-suite has been run. Used in...
5519 (Debugging a successful test, Debugging script and environment),
5520 (Debugging a failed test): ...these new tests. The first of these
5522 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5523 macro, split out from...
5524 (AT_INIT): ...here, so that using -d also generates a run script.
5525 Document that -d inhibits top-level logging.
5526 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5527 inhibits top-level logging; debug scripts are created.
5529 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5531 * tests/autotest.at (Empty test, Empty check): New test to check it.
5533 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5536 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5538 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5539 the files if a problem appears. Make the empty *.at files
5540 read-only, too. Proposed by Ralf Wildenhues.
5542 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5544 * config/Makefile.am: Add comment to force updated Makefile.in.
5546 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5547 space only patch to this file, this patch causes the Makefile.in
5548 files that include freeze.mk to be updated, and thus have a
5549 newer time stamp again, which in turn makes a pristine CVS
5550 checkout have correct time stamps.
5552 * Makefile.maint (cvs-sv): New macro, to be used..
5553 (config.guess-url_prefix, config.sub-url_prefix)
5554 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5555 point to CVS text checkout of Gnulib files.
5556 (copyright-check): Bump current year.
5557 (announcement): Do not hard-wire `./announce-gen'.
5558 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5560 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5562 (wget_files): Update config.guess, config.sub, texinfo.tex by
5563 `wget-update', now that their URLs work again.
5565 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5567 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5568 Problem noted by Paul D. Smith.
5570 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5572 * doc/autoconf.texi: Remove unused words from word list.
5573 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5574 .x-sc_trailing_space: New files.
5576 * doc/standards.texi: Sync from gnulib.
5578 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5579 `LIBOBJDIR' as experimental.
5581 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5582 with a target directory; it's internally implemented as `cp'
5583 anyway, but since Autoconf advertises the possibility to use
5584 a target directory when LN_S is `ln -s', we need to find out.
5585 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5586 analyzed by Keith Marshall <keith.marshall@total.com>.
5590 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5592 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5593 confdefs.h as-is. In general, if it has backslash-newline or the
5594 like, then it doesn't work either to sort or to remove empty
5597 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5599 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5601 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5603 * lib/autom4te.in (Automake-preselections): Preselect
5606 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5608 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5609 apostrophe within a single-quoted string, as this is the usual
5610 tradition and is easier to read than '"'"'. Don't rely on the
5611 shell treating "$/" like '$/'. Use a more-consistent indenting
5614 2006-04-09 Eric Blake <ebb9@byu.net>
5616 * tests/autotest.at (Backquote command substitution),
5617 (Multiline backquote command substitution): Remove mistaken
5618 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5620 (Parenthetical command substitution, Multiline parenthetical
5621 command substitution): here.
5623 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5625 Import macros from gnulib (often changing their name).

5655 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
5656 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
5657 (C Compiler): Move AC_C_LONG_DOUBLE to ...
5658 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
5659 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
5660 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
5661 (Coding Style). Don't mention m4_expand_once.

5683 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
5685 2006-04-08 Stepan Kasal <kasal@ucw.cz>
5687 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
5688 of the warning introduced by the 2001-08-28 change.
5690 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
5691 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5693 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
5694 variables shall be overriden by the cache.

5696 that contains braces.
5698 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5700 Revert the patch from 2006-04-01 and only improve
5701 _AS_DETECT_BETTER_SHELL:
5703 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
5704 skip nonexistent directories.
5705 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
5706 only shell candidates which exist.
5707 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
5708 * lib/autotest/general.m4 (AT_INIT): No need to give three
5709 parameters to _AS_PATH_WALK.
5711 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
5712 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5714 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
5715 distinguish m4sugar macros.
5716 * tests/tools.at (autoupdating with aclocal and m4_include):
5717 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
5718 test case by Noah Misch <noah@cs.caltech.edu>.
5720 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5722 Revert my change from 2006-03-17, in other words:
5723 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
5725 (AS_SHELL_SANITIZE): Remove DUALCASE=1.

5729 2006-04-07 Eric Blake <ebb9@byu.net>
5731 * doc/autoconf.texi (Programming in M4sh): Document that
5732 AS_MKDIR_P exits the script on failure.
5733 * lib/autotest/general.m4: Remove redundant AS_ERROR.
5735 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5737 * config/elisp-comp, config/install-sh, config/mdate-sh,
5738 config/missing, config/mkinstalldirs: Sync from Automake.

5754 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5756 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
5757 whether `set' quotes correctly: redirect stderr of the tested
5758 `set', and use a subshell, for Ultrix; use `sed' instead of
5759 `grep' for zsh `set' which may write binary output; match only
5760 at the beginning of a line, to avoid false positives.
5761 In order to avoid false positives by unrelated variables with
5762 multiline content, put the dump algorithm in a subshell and
5763 unset all variables containing newlines (except some which are
5764 special to the shell). Warn about cache variables that are

6716 2005-10-27 Stepan Kasal <kasal@ucw.cz>
6718 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
6719 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
6721 2005-10-25 Stepan Kasal <kasal@ucw.cz>
6723 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
6724 conftst2.$ac_objext.
6725 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
6727 2005-10-24 Stepan Kasal <kasal@ucw.cz>
6729 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
6730 conftest.o, to see whether the compiler really obeys; rm the object
6731 file before and after the test and register it with ac_clean_files.
6732 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
6734 2005-10-21 Stepan Kasal <kasal@ucw.cz>
6736 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
6737 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
6738 code so that the most common case requires less forks.
6740 2005-10-20 Stepan Kasal <kasal@ucw.cz>
6742 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
6743 not portable; thanks to Paul Eggert and Alexandre.
6745 * NEWS: Fix an old typo.
6747 2005-10-20 Jim Meyering <jim@meyering.net>
6749 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
6750 the latter'', in two places.
6752 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
6754 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
6755 AC_LANG_PROGRAM, fixing a typo. Don't give details about
6756 the inner workings of AC_LANG_FUNC_LINK_TRY.
6757 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
6758 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
6759 by the function rather than ignoring it.
6760 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
6761 comparing its address. Intel's interprocedural optimization was
6762 outsmarting the old heuristic. Problem reported by
6765 2005-10-19 Stepan Kasal <kasal@ucw.cz>
6767 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
6769 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
6771 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
6772 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
6774 2005-10-04 Stepan Kasal <kasal@ucw.cz>
6776 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
6777 before removing it (chmod -R u+rwx); there are three instances of this.
6779 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6780 Stepan Kasal <kasal@ucw.cz>
6782 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
6783 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
6784 make its content writable before removing it. Remove an errorneous
6785 comment from the end, where the logs of the failed tests are copied
6786 to the main log file.
6788 2005-09-27 Stepan Kasal <kasal@ucw.cz>
6790 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
6791 in case the computer is too quick. Double quote the configure.ac
6794 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
6795 problems if the testsuite were running too fast.
6797 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
6799 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
6800 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
6801 (which belong to Xt, not X itself). See Debian bug 327655.
6802 * NEWS: Mention this.
6804 2005-09-07 Stepan Kasal <kasal@ucw.cz>
6806 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
6808 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
6810 * config/move-if-change: Don't output "$2 is unchanged";
6811 suggested by Ben Elliston. Handle weird characters correctly.
6813 2005-09-06 Stepan Kasal <kasal@ucw.cz>
6815 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
6816 calls, so that the final expansion of this macro is shorter.
6817 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
6818 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
6819 the cleanup there. Use AS_VAR_* macros, to be more general.
6820 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
6822 * lib/autoconf/general.m4: Use AS_IF where appropriate.
6824 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
6826 2005-09-01 Stepan Kasal <kasal@ucw.cz>
6828 * doc/autoconf.texi (Configuration Headers): Add an index entry
6831 2005-08-26 Pavel Roskin <proski@gnu.org>
6833 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
6834 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
6837 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
6839 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
6840 The previous patch didn't work, so try a better one.
6842 2005-08-26 Stepan Kasal <kasal@ucw.cz>
6844 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
6845 in the example. Reported by Bruno Haible.
6846 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
6847 "if $undefined_var;" succeeds with my shell.
6849 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
6850 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
6851 but change the m4_divert_text to m4_divert_once.
6853 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
6855 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
6856 Work around bug in Solaris /usr/xpg4/bin/awk.
6857 The bug is present in at least Solaris 8 through 10.
6859 2005-08-24 Stepan Kasal <kasal@ucw.cz>
6861 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
6862 some evil values and relying on the fact that $* concatenates the
6863 parameters by the first character from IFS.
6865 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6866 Stepan Kasal <kasal@ucw.cz>
6868 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
6869 first header appears, define AH_HEADER.
6870 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
6871 Update limitations about when to call AC_CONFIG_HEADERS.
6872 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
6873 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
6874 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
6875 ``Configuration Actions''; fix their index entries.
6877 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
6878 options correctly. Process N-M as M-N if M is smaller than N.
6879 Process ranges correctly so that N-N will run only N.
6880 Sort and uniquify the tests that will be run. If there is more
6881 than one test, reinsert the banners for the tests.
6882 * tests/autotest.at (Keywords): Unmark XFAIL.
6884 2005-08-23 Stepan Kasal <kasal@ucw.cz>
6886 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
6887 before passing the macro name to AH_TEMPLATE.
6889 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
6890 now opens log after option processing; in particular, --version
6891 and --help do not touch config.log.
6893 * Makefile.maint: Revert the change from 2005-08-12.
6895 2005-08-22 Stepan Kasal <kasal@ucw.cz>
6897 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
6899 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
6901 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6903 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
6904 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
6907 * doc/autoconf.texi (Defining Symbols, Changed Results):
6908 Prepend to LIBS, not append, in examples.
6910 2005-08-16 Stepan Kasal <kasal@ucw.cz>
6912 When building in place, set srcdir="."; suggested by Tim Van Holder.
6914 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
6915 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
6916 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
6917 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
6918 does not mean "no --srcdir option".
6920 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6922 * tests/autoscan.at (autoscan): New file.
6923 * tests/suite.at: Use it.
6924 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
6925 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
6927 * tests/autotest.at (Keywords): Test keywords combinations.
6929 2005-08-12 Stepan Kasal <kasal@ucw.cz>
6931 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
6932 add "2>&1"; gzip 1.2.4 prints help on stderr.
6934 2005-07-27 Stepan Kasal <kasal@ucw.cz>
6936 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
6937 was pushdef'ed twice while popped only once. Push it only once.
6938 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
6940 2005-07-26 Stepan Kasal <kasal@ucw.cz>
6942 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
6943 prefixed by mere "===", not "configure: === ".
6945 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
6947 * Makefile.maint: Update from Bison.
6949 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
6950 "<tab>" in comment, so that the point is understandable.
6952 2005-07-25 Stepan Kasal <kasal@ucw.cz>
6954 Rewrite substantial part of lib/autoconf/status.m4.
6955 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
6956 and CONFIG_COMMANDS are not processed in four separate loops.
6957 Instead, there is one main loop. This alows that the common code
6958 is expanded only once, thus config.status (and configure) is smaller.
6960 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
6961 the AC_LIST_FILES and cousins macros are no longer used.
6963 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
6964 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
6965 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
6966 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
6967 contain the initialization, nor the for loop, nor the associated
6968 commands; all these go to ...
6969 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
6970 _AC_OUTPUT_CONFIG_STATUS.
6971 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
6972 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
6973 (_AC_OUTPUT_FILE): The creation of the sed script ...
6974 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
6975 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
6976 _AC_OUTPUT_MAIN_LOOP.
6977 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
6978 _AC_CONFIG_COMMANDS): Use ...
6979 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
6980 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
6981 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
6982 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
6983 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
6984 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
6986 (_AC_CONFIG_UNIQUE): Update.
6987 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
6988 Replaced by this ...
6989 (_AC_LIST_TAGS): ... new common macro.
6990 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
6991 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
6992 (_AC_LIST_TAG_COMMANDS): ... new common macro.
6993 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
6994 this didn't belong to the `config commands' section.
6995 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
6996 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
6997 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
6998 to the `config commands' section either.
6999 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7000 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7002 ... and many changes to the comments nearby.
7004 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7005 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7006 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7007 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7008 (#define header templates): The comment at the top of the generated
7009 header now includes the name(s) of the source file(s).
7011 Several unrelated small changes:
7013 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7014 parameter to AC_DIAGNOSE.
7015 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7016 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7017 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7018 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7020 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7021 in AC_OUTPUT doesn't double-quote it either.
7022 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7025 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7027 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7028 versions of Portland Group compiler produce single- and double-quoted
7029 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7030 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7032 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7034 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7035 This is a corrected version of yesterday's patch.
7037 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7039 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
7040 path, too; insert a "===" to emphasize the line.
7042 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
7043 ac_cv_build_alias to ac_build_alias.
7044 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7046 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7047 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7048 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7049 (AC_ARG_VAR): ... here.
7050 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7053 Keep a list of all precious variables and process them with one simple
7054 for loop, instead of expanding all commands, or, OTOH, complicated
7055 processing of output of "set".
7056 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
7057 variable names in new macro...
7058 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
7059 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
7060 a loop to assign all ac_env_* and ac_cv_env_* variables.
7061 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7063 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7064 its value to shell variable ac_precious_vars and call
7065 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
7066 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
7067 _AC_ARG_VAR_VALIDATE.
7069 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
7070 and the AC_SUBSTs ...

7087 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7088 They are generated by the Tru64 v5.1B shell.
7090 2005-07-05 Stepan Kasal <kasal@ucw.cz>
7092 Fix my changes from 2005-07-01; reported by Noah Misch.
7093 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
7094 description, the macro now accepts only a single tag.
7095 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
7097 Fix cases when the varsions of Autoconf and Autotest don't match.
7098 Reported by Noah Misch.
7099 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
7100 at_top_builddir, for compatibility with older autotest.
7101 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
7102 is not set, use at_top_builddir, for compatibility with older
7103 versions of autoconf.
7105 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7107 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
7108 Problem reported by Patrick Welche.
7110 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
7112 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7113 sed substitution command, so that we allow | in program prefixes
7114 and program suffixes. (& is a problem anyway; we're not fixing
7116 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
7117 configure_input, top_builddir, srcdir, etc.
7118 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7119 PATH_SEPARATOR in AUTOTEST_PATH.
7121 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
7123 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
7124 for loop over config.site files using `set', to allow
7125 directory names containing IFS characters.
7127 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
7129 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
7130 directories with weird names. Apparently some people like living
7131 on the edge. However, improve the test that "pwd" actually does
7132 report a name for the working directory.
7133 * NEWS: Remove the claim that we test for funny chars in dir names.
7135 2005-07-01 Stepan Kasal <kasal@ucw.cz>
7137 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's

7148 (Generic Functions): Mention the Gnulib project.
7149 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
7151 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
7152 document to output the default config_* lists to config.status.
7153 Don't recognize option --file, if the functionality is not there.
7154 Likewise for --header; moreover, recognize --he and --h as shortcuts
7155 for --help in that case.
7157 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7158 matches the order of execution. No code changed.
7160 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7162 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for

7179 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
7180 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7181 (AC_SUBST): Call it.
7182 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7183 the directory specific variables; but don't call it for configure_input.
7185 2005-06-28 Derek Price <derek@ximbiot.com>
7187 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7190 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7192 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
7193 directory have inherent problems with special characters like spaces,
7194 due to limitations in Make syntax. Problem reported by Alexandre
7196 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
7197 Also, fix Tru64 porting problem with shell patterns,

7209 from Justace Clutter.
7210 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7211 variable into diagnostic. Make the diagnostic an error, not a warning,
7212 because we really don't support spaces and suchlike in dir names.
7213 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7214 Don't worry about backslashes in srcdir; it can't happen now.
7215 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
7216 Simplify ac_optarg handling.

7225 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
7227 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
7228 that '\|' is not allowed in BREs; recommend using newline separated
7229 list of patterns instead of multiple -e options.
7231 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
7233 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

7243 (Special Shell Variables): Fix sed code this in the example.
7244 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7245 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
7247 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

7253 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
7255 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
7257 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
7258 * doc/autoconf.texi:
7259 Don't mention Solaris versions so much, if a
7260 problem is common to all extant versions of Solaris. Say "SunOS
7261 4" instead of "SunOS" for SunOS 4.
7262 (awk): Mention more of the limitations of traditional Awk.
7263 (cat): Don't talk about cat -v.

7273 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
7274 on Mac OS X 10.4 reported by Peter O'Gorman in:

7279 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
7281 * doc/autoconf.texi: "filesystem" -> "file system".
7282 "behaviour" -> "behavior".
7283 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
7284 * lib/autoconf/general.m4: Omit blank after ":" sed command,
7286 * lib/m4sugar/m4sh.m4: Likewise.
7287 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
7288 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
7290 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
7291 (.x.1): Ignore the time stamp in the .TH line when deciding whether
7292 to update the man page. That way, we don't have to check in new
7293 man pages every month.
7295 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
7296 quotes and backslashes. Patch from Derek Price.

7303 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
7305 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7306 -u, since it outputs chatter if the input files are the same.
7307 Problem reported by Ralf Menzel.
7309 2005-06-08 Derek Price <derek@ximbiot.com>
7311 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7312 renaming them since they are about to be redefined anyhow.
7314 2005-06-08 Derek Price <derek@ximbiot.com>
7316 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7317 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7318 Move m4_undefine to alphabetical order.
7320 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
7322 * README: Recommend GNU M4 1.4.3 or later.
7323 * doc/autoconf.texi (Introduction): Likewise.
7324 Reword to avoid some formatting glitches.
7325 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7326 Clarify explanation of HP compiler bug.
7327 Redo example output tp match current CVS snapshot.
7328 Use @example.org in email addresses when the examples
7329 might get inadvertently cut-and-pasted into user code.
7330 Remove example of autom4te usage that doesn't seem to work now.
7331 Use modern AC_INIT (except when the example is meant to be
7332 shown with Autoconf 2.13).
7333 Update ksh info for Solaris 9 and later.
7335 Modernize description of Automake versions a bit.
7336 Don't claim a future version of Autoconf is near.
7337 * doc/install.texi: Reword to avoid some formatting glitches.
7339 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7342 follows its own advice about quoting better.
7343 Reword to avoid some formatting glitches.
7344 * doc/installt.exi: Reword to avoid some formatting glitches.
7346 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7347 Tru64 ksh pattern matching bug. Reported against Libtool by
7348 Albert Chin <libtool@mlists.thewrittenword.com> and
7349 Nicolas Joly <njoly@pasteur.fr>.
7351 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7353 m4_cdr of one-member list was [[]] (one-member list containing an
7354 empty string) instead of [] (an empty list. Callers were skewed to
7355 match this misbehaviour. As a consequence of this:
7356 - m4_foreach([x], [], [foo]) expanded to `foo', while
7357 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7358 This bug has been fixed:
7360 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7361 expand to an empty string; print error msg if called without
7363 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7364 misbehaviour; handle [] and [[]] correctly.
7366 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7368 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

7370 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
7372 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7374 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7375 swallow records with more than 99 fields.
7376 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7377 parse the long line.
7379 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7381 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7382 swallow literals longer than 399. Reported by Ralf Wildenhues.
7383 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
7384 to workaround this limitation.
7386 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
7388 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7389 to gfortran, and make these the first two compiler names
7390 checked (following the general autoconf preference for gcc).

7394 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7395 (DISTCLEANFILES): Remove $(check_SCRIPTS).

7400 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7401 expression of unbounded size when processing the --list
7402 option. This runs afoul of a limit of 399 bytes per regular
7403 expression on AIX. Problem reported by Ralf Wildenhues.
7405 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

7408 * doc/autoconf.texi (Particular Headers): Reword example
7409 for multiline stdbool replacement.
7410 (Setting Output Variables): Reword text a bit. Don't
7411 give all the details about |#_!!_#|.
7412 Reword description of line replacement.
7414 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7416 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7417 now contain newlines, and substituted files must be referenced on
7418 a line alone; the sed scripts to substitute them are now very
7420 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
7421 commands can be put in a sed script portably.
7422 * doc/autoconf.texi (Setting Output Variables): Document above
7423 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
7424 use of multiline substitution.

7434 * tests/local.at: Don't attempt to check for negated character
7435 classes in shell scripts. The test was too brittle.
7437 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7439 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
7440 * doc/autoconf.texi (Limitations of Builtins): Document this
7443 2005-05-24 Stepan Kasal <kasal@ucw.cz>
7445 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
7446 common code; used in many places in the tree.
7447 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
7448 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
7450 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.

7453 messages when ac_unique_file is not found.
7454 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7455 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
7456 commands, for consistency with AC_MSG_ERROR and such.
7458 * bin/autoconf.as: Make more use of "shift 2" in option processing.

7471 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7472 (ac_top_builddir): ... this ...
7473 (ac_top_build_prefix): ... to this; the old name is also kept, for
7474 backward compatibility.
7475 (ac_top_builddir_sub): New variable, without the trailing slash,
7477 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

7491 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7492 argument to m4_foreach. I guess it was necessary in the past,
7493 but I think it's a no-op now.

7497 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7498 ``cat <<_ACEOF'' commands to one.

7716 ac_pwd, and quote srcdir.
7717 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
7719 * doc/autoconf.texi: Fix some systematic formatting problems.
7720 ".)" needs a following @: if not at the end of a sentence, and

7738 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
7739 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
7740 from a Common Lisp's `cl'.
7741 (AC_PROG_CXX): Behave according to the documentation: don't
7742 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
7743 make the variable CCC precious; use `cl.exe', not `cl'.

7748 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
7749 /dev/null, as "configure" shouldn't read stdin, and this insulates

7751 redirection before invoking "hostname" or "uname", and keep the
7752 original input stream available via...

7789 before invoking "hostname" or "uname".

7964 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
7965 Update the long comment explaining it.
7967 m4_require no longer writes an ``is required by'' line to the
7968 execution stack. It contains only one bit of non-redundant
7969 information: that the macro was required, not called. And even
7970 this bit is useless in most situations: have you ever met a macro
7971 which both calls and requires the same macro?
7973 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
7974 (_m4_defun_pro_outer): ... only via this macro, for the outermost

8022 Warn about newline stripping in `` and $(). Update Solaris
8024 (Limitations of Builtins): Use expr "X...", not expr "x...", as
8025 X insulates us from future changes to Posix.

8079 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8080 stored in _m4_divert_diversion or _m4_divert_dump.
8081 (m4_divert_pop): When the parameter is given, compare the symbolic
8082 name with the last diversion pushed on the stack. Previously, the
8083 current diversion was compared with the numeric value of the
8084 diversion given as the parameter.
8085 (m4_require): If the macro hasn't been expanded yet, call ...

8577 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in

8580 More fixes to support spaces in the name of the build directory.
8581 This isn't a complete fix but it's an improvement.
8583 * bin/autoconf.as (autom4te_options): New var.
8584 Use it instead of appending to AUTOM4TE, so that we can allow
8585 spaces in the build directory's absolute name.
8586 * bin/autoheader.in ($autoconf): Allow spaces in file names.

8659 names like "aux". Problem reported by Eric Blake.
8661 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
8662 by zero instead of array size, so that we can use any arithmetic
8663 constant expression (instead of requiring an integer constant
8664 expression). This allows us to test expressions like DBL_MAX <
8665 LDBL_MAX, which didn't conform to the C standard using the old
8667 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
8668 now that we can do floating-point tests at compile time.
8670 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8672 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8673 and LDBL_EPSILON, as the resulting expression isn't an
8674 integer constant expression and violates the C standard.
8675 Problem reported by Nelson H. F. Beebe. Also, check
8676 for "L" suffix, and check that long double doesn't have
8677 worse range or precision than double, that mixed-mode
8678 arithmetic doesn't generate a diagnostic, that double
8679 constants fit in long double.

8711 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8712 function F exists if the compiler and linker let you compile an
8713 expression like (F != 0). Recent versions of GCC optimize away
8714 the reference to F in that case, since every function address must
8715 be nonzero, so the link succeeds even if F does not exist.

8735 note pessimistic assumption when cross compiling.
8737 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
8739 * doc/autoconf.texi (Limitations of Make): Note that BSD make
8740 (until 2004) invoked subcommands with sh -e, contra POSIX.
8741 Reported by Kevin Ryde.
8743 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
8745 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
8746 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
8747 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
8748 `test -f " /usr/bin/grep"', which _always_ failed.
8749 (AC_PROG_SED): Ditto bogus PATH fix.
8750 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
8751 requires that grep correctly supports _multiple_ `-e' options, rather
8752 than stating only that grep should accept `-e'.
8754 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
8756 Port to C99, which requires that 'exit' be declared.
8758 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
8759 to ensure that stdlib.h is included.
8760 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
8761 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,

8764 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
8765 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
8766 when using 'exit' in a test; C99 requires that 'exit' be declared.
8768 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
8770 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
8771 now prefers 'grep' implementations that accept -e.
8772 (Limitations of Usual Tools): Describe problems of traditional
8773 egrep and fgrep with long input lines, and of traditional grep
8775 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
8776 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
8777 All callers changed. Append /usr/xpg4/bin to the PATH, for
8779 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
8780 the user with complaints about multiple -e options.
8781 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
8782 Define it with AC_PROG_GREP.
8783 * configure.ac (AC_PROG_GREP): Add.
8784 * lib/freeze.mk (GREP): New macro.
8786 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
8788 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
8789 a possible candidate only after all others fail, rather than
8790 consulting it first. This improves backward compatibility by
8791 better reflecting the way shell selection occurred in previous
8792 versions of Autoconf, and should help to avoid triggering latent
8793 problems in other packages, such as the one in Automake where zsh
8794 is not handled robustly:
8795 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
8796 Although it is not Autoconf's responsibility to work around
8797 problems in Automake, it nevertheless makes sense to avoid
8798 introducing unnecessary incompatibilites.

8801 Gary V. Vaughan <gary@gnu.org>
8803 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
8804 how deeply nested we are when a suitable tool is found, set the
8805 ac_path_TOOL_found flag.
8806 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
8807 nested we are in this macro. Break out of all 3 nested loops if
8808 ac_path_TOOL_found is set.
8810 2004-04-21 Gary V. Vaughan <gary@gnu.org>
8812 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
8813 of the _AS_PATH_WALK loop too if GNU flavor is found.
8815 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
8817 * doc/autoconf.texi (Limitations of Make): Update documentation
8818 for `$<'. New entry `Long lines', based on a report from Simon
8819 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
8820 paragraph about DJGPP, based on a mail from Richard Dawe.
8822 2004-04-20 Paul Eggert <eggert@twinsun.com>
8824 * tests/c.at (C keywords): Don't assume that GCC supports
8825 "restrict" and "inline", as sufficiently-old GCC versions do not
8826 (also, GCC configured to be in pedantic C89 mode does not).
8827 Problem reported by Sumit Pandya in:
8828 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
8830 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
8831 consider -g to work if it generates warnings when plain compiles
8832 don't. Problem reported by Braden McDaniel in:
8833 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html

8840 linker output files before linking, to work around IRIX 6 linker bug.
8841 Problem reported by Rainer Orth in:
8842 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
8844 2004-04-20 Gary V. Vaughan <gary@gnu.org>
8846 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
8847 best tool so far counter rely on the tool path variable name to
8848 avoid checks for one tool being affected by the results of running
8849 the length check on a previous tool.
8851 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
8852 match expression argument, as different greps have different
8853 regular expression flavours.
8854 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
8856 (AC_PROG_EGREP): Pass 'EGREP$'.
8857 (AC_PROG_GREP): Pass 'GREP$'.
8859 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
8861 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
8862 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.

8866 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
8867 Types, Specific Compiler Characteristics, System Services,
8868 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
8869 etc. consistently instead of 'long', 'short', 'unsigned' etc.
8870 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
8871 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

8884 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
8885 now defines HAVE_DECL_TZNAME if it is declared, when
8886 HAVE_STRUCT_TM_TM_ZONE is not defined.
8887 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
8888 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

8899 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
8900 Fortran compiler is ifort, also added pghpf; thanks to Nelson
8901 H. F. Beebe for the bug report.
8903 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
8905 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
8906 quoted -cmdline argument in Portland Group compiler (bug
8907 reported by Jeffrey J. Barteet).
8909 2004-03-25 Kevin Ryde <user42@zip.com.au>

8955 2004-03-03 Paul Eggert <eggert@twinsun.com>
8957 * bin/Makefile.am (edit): Don't use $< in a context where
8958 POSIX doesn't require support for it. Use $@.in instead.
8959 Problem reported by Anthony N. Frasso in
8960 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

8971 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
8972 is not always thread-safe. Report from Nathanael Nerode.
8974 2004-02-18 Paul Eggert <eggert@twinsun.com>
8976 Fix a dependencies problem, stemming from a Autoconf 2.59 build
8977 problem on QNX reported by Stephen Rasku in

8992 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
8993 Darwin uses -lcrt2.o and there's little point to cataloging all
8994 the system variants. Partial fix reported by Andreas Waechter in:

9119 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9120 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9121 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9122 not <inttypes.h>. Problem reported by Tim Mooney in
9123 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9124 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9127 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9128 otherwise "make check" fails because it forbids cmp (I guess

9144 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9145 -std1 disables some useful extensions on Tru64. Problem reported

9149 2004-01-14 Paul Eggert <eggert@twinsun.com>
9151 * doc/autoconf.texi (Programming in M4sh): Document that
9152 AS_MKDIR_P succeeds if the destination is a symbolic link
9153 to an existing directory.
9154 (Limitations of Usual Tools): Note that mkdir -p might not
9155 succeed on symlinks to directories.
9157 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9159 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

9173 2004-01-09 Paul Eggert <eggert@twinsun.com>
9175 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9176 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9177 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9178 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9179 AC_COMPILE_IFELSE, since we now assume our caller invokes
9180 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9181 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9182 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9183 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9185 2004-01-07 Paul Eggert <eggert@twinsun.com>
9187 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9188 `"'...'"`, as it's confusing (and I suspect it may not work on
9189 some platforms). The code was incorrect anyway, as it assumed
9190 that \$ evaluated to itself in that context. Reported by
9191 Alexandre Duret-Lutz.
9193 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9195 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

9245 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9246 -c -o might not work. From a suggestion by Kevin Ryde.
9247 (C Compiler, Generating Sources, Limitations
9248 of Usual Tools, Limitations of Make, Making testsuite Scripts):

9261 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9263 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9264 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

9277 * tests/atlocal.in: Store the result here.

9546 Issue a more-informative diagnostic.
9547 Problems reported by Eric Sunshine.
9549 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
9551 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
9552 -mGLOB_options_string stuff for Intel ifc, which can cause
9553 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
9554 pattern-matching instead of grep.
9556 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
9558 * doc/autoconf.texi: Document new FC Fortran macros.

9571 -lcrtbegin.o to list of ignored flags and fix underquoting of
9574 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
9576 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
9577 cache variable instead of $G77 to decide whether to include -O2,
9578 since $G77 is specific to Fortran 77.
9580 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9582 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
9583 free" flag. Re-order flags tested into rough order of popularity.
9585 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9587 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
9588 arguments so that it can be used with syntax identical to
9589 AC_PROG_F77, and so that we can more easily decide to
9590 remove/deprecate the DIALECT optional argument in the future if it

9657 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
9658 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
9659 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

9664 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
9665 directory for AC_CONFIG_COMMANDS' first argument exists.
9666 This makes valid the invocation of _AC_SRCPATH that follows.
9667 Reported by Eric Sunshine.
9668 * doc/autoconf.texi (Configuration Commands): Adjust.
9670 2003-09-26 Akim Demaille <akim@epita.fr>

9691 The test suite are sometimes assigning timings incorrectly.
9692 Reported by Henk Krus.
9693 Diagnosed by Nicolas Joly.
9695 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
9697 Instead of making AT_help a sequence of assignments to grow
9698 $at_help_all, just make AT_help_all be the growing contents of
9699 $at_help_all, and make a single assignment in...
9701 (at_times_skip): Flip the meaning and rename as...

9704 $at_times_file after use, and check it is present before trying to

9711 * bin/Makefile.am (edit): Handle '@configure_input@'.
9712 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
9713 (ifnames): chmod -w.
9714 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
9715 executables, not bin/ executables! Otherwise all the magic needed
9716 to find non installed files is turned off. This caused a failure
9717 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
9718 as found in its environment (sent by tests/autoreconf): pointing
9719 to bin/autom4te that could not find its files.
9720 * tests/mktests.sh: Force the replacement of generated files, for
9721 the sake of "mv" program that are interactive when overwriting a

9733 Trivial change to support GCC's configuration procedure.

9816 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
9818 Add support for newer Fortran dialects. The F77 interface is
9819 unchanged, and continues to support Fortran 77. New FC macros
9820 correspond to all the old F77 macros, with output variables FC,
9821 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
9822 available dialect, but older dialects can be specified. There are
9823 new macros AC_FC_SRCEXT to set the source extension, and
9824 AC_FC_FREEFORM to accept free-form source files.

9861 * tests/local.at: Require 2.57.
9862 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
9863 are defaulted by AT_CHECK anyway.
9864 Use AT_CHECK_AUTOM4TE.

9940 Use &verb, not &verbose.
9942 2003-08-21 Akim Demaille <akim@epita.fr>
9944 * bin/autoheader.in (&parse_args): Use &parse_warnings and
9946 ($help): Use Autom4te::ChannelDefs::usage.
9947 * bin/autoscan.in: Use Autom4te::ChannelDefs.

9950 2003-08-21 Akim Demaille <akim@epita.fr>
9952 First stab at preserving warnings between calls to autom4te,
9953 including when the cache is used.
9955 There are still several issues: (i) there are too many runs of m4
9956 (one for include, one for warnings, and some more), (ii) warnings
9957 spreading on several lines are not handled gracefully, (iii) the
9958 code meant to have the call stack display for errors does not work
9959 (its handling should move from m4 to autom4te).
9961 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
9963 (@preselect): Add m4_warn.
9964 ($exit_status): Remove, use $exit_code.
9965 ($help): Use Autom4te::ChannelDefs::usage.
9966 (&handle_m4): No longer define the m4_warnings.
9967 At each run, extract and report the warnings.
9968 Always cache the result, including if the exit status is on
9969 failure, since if nothing changes, we should result in the same
9970 failure, hence we can use the cache.
9971 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
9972 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
9974 (m4_warn): Redefine as a do-nothing: it is its invocation that
9975 matters, as warnings are now reported via traces.
9976 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
9977 the contents of m4_warn: make it _call_ m4_warn, so that tracing
9978 the latter reveals calls to the former.
9982 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
9984 2003-08-21 Akim Demaille <akim@epita.fr>

10110 -lcrt1.o, for OS X. (trivial change)

10121 'long', not 'int', for benefit of Sun's recent C++ compilers
10122 (trivial change). See:
10123 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

10139 From Gareth McCaughan.
10141 2003-06-23 Akim Demaille <akim@epita.fr>
10143 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10144 not all of them. This fixes 1. the fact that when testing
10145 Autoconf there are many many config.log, 2. the incorrect use of
10146 top_srcdir to find config.log.
10147 Don't mix the detailed output of failed test with the summary of
10148 failures. Rather, append detailed log afterwards.
10150 2003-06-23 Akim Demaille <akim@epita.fr>
10152 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
10153 always run: output config.log on $at_group_log.

10157 * tests/torture.at (#define header templates): Don't use quotes in

10211 (AT_INIT): Support for expected failures.
10213 2003-06-02 Akim Demaille <akim@epita.fr>

10222 2003-05-28 Paul Eggert <eggert@twinsun.com>
10224 * NEWS, doc/autoconf.texi (Particular Functions),

10230 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10231 (handle_exec_errors): New function. Work around $! being
10232 altered by WEXITSTATUS.
10233 (xqx, xsystem): Use handle_exec_errors.
10235 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10237 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10238 Do not call `_exit()', simply modify `$?'.
10239 (xsystem): Reset $! before running system, and check it afterward.
10240 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10241 63 for version mismatches.
10243 2003-05-23 Akim Demaille <akim@epita.fr>
10245 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10246 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10247 the middle of a line).
10248 * lib/m4sugar/m4sugar.m4: Likewise.
10249 Remove useless spaces in comments.
10251 2003-05-23 Akim Demaille <akim@epita.fr>
10253 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10254 exit 63, so that we (or Automake's "missing") can tell the
10255 difference with a plain failure.
10256 * doc/autoconf.texi (Notices): Adjust.
10258 2003-05-23 Akim Demaille <akim@epita.fr>

10262 White spaces cleanup.

10265 Paul Eggert <eggert@twinsun.com>
10267 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10268 Remove `#include <stdlib.h>' from the list; we should never
10269 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10270 resulting namespace pollution would cause other tests to fail.
10271 Configure scripts run with some older versions of g++ and HP's
10272 aCC would fail due to such an #include. Problems reported by
10273 Matthew Mueller in <http://bugs.debian.org/120704> and by
10275 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10276 In the test, use the test declaration before including <stdlib.h>,
10277 as that's closer to how it'll be used.
10279 2003-05-23 Akim Demaille <akim@epita.fr>
10281 * doc/autoconf.texi (Header Portability): ucred.h.
10284 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10286 Overhaul Autotest's logging: generate separate log files
10287 in testsuite.dir/NNN/testsuite.log, and append them to
10288 testsuite.log instead of re-running the test verbosely.
10290 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10291 file descriptor, write 0 to at_status_file instead of setting
10292 at_status=0, initialize some new variables (at_status_file,
10293 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10294 to rerun the tests, instead append the at_group_log to the
10295 at_suite_log when a test fails.
10296 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10297 with the AS_MESSAGE_LOG_FD redirected to stdout.
10298 (AT_CLEANUP): save the output status in $at_status_file
10299 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10300 its original place.
10301 (AT_CHECK): since tests are run with a redirected stdout,
10302 and used to be re-run in verbose mode, turn some $at_verbose
10303 into echo, and don't redirect the output of testing stdout
10306 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10307 the name of the debugging directory and information about

10424 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
10427 2003-05-06 Akim Demaille <akim@epita.fr>
10429 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10430 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10431 by aclocal.m4 is changed it might require the importing of another
10432 m4 extension file, i.e., aclocal must be run.
10434 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10435 (&parse_args): Use --force with aclocal if required and supported.
10436 (&autoreconf_current_directory): Use &run_aclocal.
10438 2003-05-06 Akim Demaille <akim@epita.fr>

10445 open during the whole autom4te run.
10446 ($icache_file): New.

10449 2003-04-29 Derek Price <derek@ximbiot.com>
10451 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10452 seperator with m4_append_uniq(). It doesn't work.
10453 (AT_CLEANUP): Add `;' to end of at_help_all.
10454 (AT_INIT): Allow --keywords to be specified more than once. When
10455 grepping $at_help_all for keywords, use the field and keyword
10456 seperators to ensure a complete keyword match. Alter at_prev handling
10457 to support the new --keywords behavior.
10459 2003-04-27 Karl Berry <karl@freefriends.org>
10461 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10462 align better with others. I also made some of the individual
10463 entries on one line, for brevity and to make it easier for me to
10464 sort my dir-example file in the Texinfo distribution :).

10531 header causes problems.
10533 2003-03-28 Akim Demaille <akim@epita.fr>
10535 * tests/torture.at (Configuring subdirectories): Require aclocal
10536 1.4, otherwise the test fails, as it does support configure.ac.
10537 This fixes the "test 40 failed" bug reports.

10559 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
10560 obsolete AC_HELP_STRING.
10561 (AC_HELP_STRING): AU_DEFUN to...
10562 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
10563 * tests/m4sh.at (AS_HELP_STRING): New test.
10565 * tests/acgeneral.at: Regenerated.
10567 2003-03-26 Derek Price <derek@ximbiot.com>
10569 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
10570 sense. Verbosify the diversion definitions comment.

10608 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
10609 Tru64 make in the "target lookup" section.
10610 (Automake): Automake 1.5+ no longer requires special tools to be
10611 present on the developer's host.
10613 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
10615 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
10616 to a shell that can handle redirection or quoting correctly.

10621 * bin/autoscan.in (BEGIN): Likewise.
10622 * bin/autoupdate.in (BEGIN): Likewise.
10623 * bin/ifnames.in (BEGIN): Likewise.
10625 * bin/ifnames.in: Add final newline to help and version messages.
10627 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
10628 to cope with DOS-style absolute paths, when constructing
10631 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
10632 When constructing paths with IFS=:, quote the path. If we're
10633 constructing a DOS-style absolute path, we don't want to split it
10636 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
10639 2003-02-25 Pavel Roskin <proski@gnu.org>

10647 2002-09-01 patch by replacing "test -n" with "test -z".
10648 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
10649 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
10651 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
10652 to fix a mismatch between example and discussion.
10654 2003-02-24 Kevin Ryde <user42@zip.com.au>
10656 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
10657 format starting with "-".
10659 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
10661 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
10662 is not portable inside Makefile.
10664 2003-02-20 Akim Demaille <akim@epita.fr>
10666 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
10667 compiler says yeah, but preproc says nope, compiler is right.
10668 Conversely, prompt the reader to send a bug report to the
10669 maintainers of the package, not of Autoconf.
10671 2003-02-20 Klee Dienes <kdienes@apple.com>
10673 * bin/autoreconf.in (autoreconf_current_directory): Properly
10674 handle an empty aclocal.m4.

10679 $ac_prefix_program.
10682 2002-12-23 Paul Eggert <eggert@twinsun.com>
10684 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10685 innocuous variant befor including <limits.h> or <assert.h>. This
10686 works around a bug reported by Albert Chin: HP-UX 11i
10687 (and earlier versions) have a <limits.h> that declares
10688 gettimeofday and many other functions.
10690 2002-12-03 Paul Eggert <eggert@twinsun.com>
10694 * NEWS, configure.ac: Update version.
10696 * doc/fdl.texi: Upgrade to FDL version 1.2.
10698 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
10699 nontrivially in main's body, so that f's external declaration is
10700 not optimized away in AIX. This should fix the bug reported by
10702 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
10704 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10705 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10706 defined, to support freestanding compilers. This should fix the
10707 bug reported by Momchil Velkov in
10708 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10710 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10711 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
10712 obsolete AC_CHECK_TYPE. The missing empty arg was reported

10714 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
10716 * Makefile.maint (www-gnu): New macro.
10717 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
10718 the location has moved.

10722 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
10723 \(.*\) match is too long and there is something more to be checked.
10724 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
10726 2002-11-15 Akim Demaille <akim@epita.fr>

10742 Update from masters.
10744 2002-11-14 Akim Demaille <akim@epita.fr>
10746 * Makefile.maint: Sync with Bison, i.e.:
10747 (po-check): Scan .l and .y files instead of the
10748 .c and the .h files that they generate. This fixes the bug
10749 reported by Tim Van Holder in:
10750 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
10751 Look for N_ as well as for _. Try to avoid matching #define for
10755 2002-11-14 Akim Demaille <akim@epita.fr>
10757 * doc/autoconf.texi (C Compiler): Compiling several files at once.
10758 From Paul Eggert and Albert Chin-A-Young.
10760 2002-11-14 Akim Demaille <akim@epita.fr>
10762 * doc/autoconf.texi (C Compiler): Solitary backslashes.
10763 From Paul Eggert and Albert Chin-A-Young.
10765 2002-11-14 Kevin Ryde <user42@zip.com.au>
10767 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
10768 than assigning in main, to avoid HP cc +O3 optimizing it away.
10770 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
10772 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
10773 option. Process --recheck after parsing all options. Pass -q
10774 option to configure on --recheck.
10775 (AC_OUTPUT): Pass -q from configure to config.status.
10776 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
10777 arguments to record.
10778 * doc/autoconf.texi (config.status Invocation): Document
10779 config.status -q option.
10781 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
10783 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
10784 Makefile.in if Makefile.am exists.
10785 (output): Strip `.am' from Makefiles. Don't
10786 output AC_CONFIG_FILES if no Makefiles were found.

10806 Reported by Ezra Peisach.
10808 2002-11-05 Akim Demaille <akim@epita.fr>
10810 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
10812 We _have_ to stop using the old compatibility scheme that tried to
10813 avoid useless backslashes because Libtool 1.4.3 contains a
10814 AC_DEFINE([error_t], [int],
10815 [Define to a type to use for \`error_t' if it is not
10816 otherwise available.])
10817 We _have_ to quote the single quote and backslashes with \. The
10818 old compatibility scheme saw that ` was backslashed, and therefore
10819 did not quote the single quote. Hence before this patch, Autoconf
10820 was not compatible with Libtool.
10822 2002-11-04 Paul Eggert <eggert@twinsun.com>
10824 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

10841 (&autoreconf): here.
10842 ($help, $make, &parse_args, &autoreconf_current_directory):
10844 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10846 2002-10-31 Bruno Haible <bruno@clisp.org>

10862 2002-10-31 Akim Demaille <akim@epita.fr>
10864 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
10865 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
10866 Make variable, not a shell variable.
10867 Suggested by Bruno Haible.
10869 2002-10-31 Akim Demaille <akim@epita.fr>
10871 * bin/autom4te.in (load_configuration): Reject #args out of any
10874 2002-10-31 Akim Demaille <akim@epita.fr>
10876 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
10877 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
10878 (_AC_RUN_IFELSE): Use it.
10879 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):

10888 Suggested by Tim van Holder.
10890 2002-10-29 Paul Eggert <eggert@twinsun.com>
10892 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
10893 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
10894 Problem reported by Bruno Haible.
10896 2002-10-29 Akim Demaille <akim@epita.fr>
10898 * doc/autoconf.texi (Header Templates): Put also in words what the
10899 pictures says to assist free style readers.
10900 (Customizing autom4te): s/--cache=/--cache /.
10902 2002-10-29 Akim Demaille <akim@epita.fr>
10904 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
10906 sparc_address_test returns void.
10907 Use it with an argument, as prototyped.
10910 2002-10-29 Akim Demaille <akim@epita.fr>
10912 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

11211 Reported by Alexandre Duret-Lutz.
11213 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

11274 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11275 aclocal invocation, as Gettext macros might not be visible to

11278 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11279 Reported by Paul D. Smith.
11281 2002-10-08 Paul Eggert <eggert@twinsun.com>

11311 * tests/torture.at (Configuring subdirectories): Be robust to

11476 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
11477 reading config.log when the compiler is rejected.
11478 Suggested by Guido Draheim.
11480 2002-09-13 Akim Demaille <akim@epita.fr>
11482 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11483 (chdir_init) might hang when stat'ing mounted directories.
11484 Reported by Vance Shipley.
11486 2002-09-12 Akim Demaille <akim@epita.fr>
11488 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
11491 2002-09-12 Akim Demaille <akim@epita.fr>
11493 * doc/autoconf.texi (Defining Symbols): Present two different
11494 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
11495 difference between 1 argument calls, and 2-3 argument calls.
11497 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
11499 * doc/autoconf.texi: Review grammar and punctuation.
11501 2002-09-11 Paul Eggert <eggert@twinsun.com>
11503 * doc/autoconf.texi: Fix minor formatting, spelling, and
11505 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
11506 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
11509 2002-09-11 Akim Demaille <akim@epita.fr>
11511 * doc/autoconf.texi (Questions): Rename as...
11513 (Defining Directories): New.
11515 2002-09-09 Akim Demaille <akim@epita.fr>
11517 * doc/autoconf.texi (Making testsuite Scripts): Update.
11518 Suggested by Nishio Futoshi.
11520 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
11522 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
11523 plain `@' is wanted.
11525 2002-09-09 Akim Demaille <akim@epita.fr>
11527 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11528 `duplicates', since the algorithm was too naive and could keep
11529 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11530 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11531 Reported by Ralf Corsepius.
11532 * tests/torture.at (Configuring subdirectories): Exercise these
11535 2002-09-09 Akim Demaille <akim@epita.fr>
11537 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
11538 looking for a replacement file.
11539 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11540 directory is relative.
11541 * doc/autoconf.texi (Generic Functions): Clarify the replacement
11542 directory definition.
11543 Reported by Andreas Schwab and Jim Meyering.
11545 2002-09-06 Akim Demaille <akim@epita.fr>
11547 * doc/autoconf.texi (Setting Output Variables): Clarify what
11548 precious variables are.
11549 Suggested by Pontus Skoeld.
11551 2002-09-05 Akim Demaille <akim@epita.fr>
11553 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11554 (ifnames, autoscan, autom4te): Since we don't only depend on
11555 configure.ac variables (such as VERSION etc.), but also on prefix
11556 and so forth, depend on Makefile, not configure.ac.
11557 Reported by Alexandre Duret-Lutz.
11558 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11560 2002-09-05 Kevin Ryde <user42@zip.com.au>
11562 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11563 doesn't seem to be confined to ia64, just say "some versions".
11565 2002-09-04 Akim Demaille <akim@epita.fr>
11567 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11569 * Makefile.am (maintainer-clean-local): Remove.
11570 (MAINTAINERCLEANFILES): Remove COPYING.
11572 2002-09-03 Paul Eggert <eggert@twinsun.com>
11574 * doc/autoconf.texi (Configuration Commands): Remove obsolete
11575 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
11578 2002-09-03 Akim Demaille <akim@epita.fr>
11580 * configure.ac: Bump to 2.53d.
11581 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11582 as of today, on Automake's team suggestion.
11584 2002-09-03 Akim Demaille <akim@epita.fr>
11588 2002-09-02 Akim Demaille <akim@epita.fr>
11590 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
11592 * configure.ac: Disable SITE_MACRO_DIR.
11594 2002-09-02 Jim Meyering <meyering@lucent.com>
11596 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11597 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11598 Also, tweak grammar: s/make sure to/be sure to/.
11600 2002-09-02 Paul Eggert <eggert@twinsun.com>
11602 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11603 directory names are generally preferable to physical names.
11605 2002-09-02 Akim Demaille <akim@epita.fr>
11607 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11608 Reported by Raja R. Harinath.
11609 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11610 * bin/autoupdate.in: Use error instead of die.
11612 2002-09-01 Paul Eggert <eggert@twinsun.com>
11614 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11615 ordinary shell concatenation rather than echo+tr+sed command that
11616 runs afoul of a long-line-related sed bug in Solaris 8.
11618 * bin/autoheader.in (parse_args): --warning -> --warnings.
11620 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11621 stdout, as traditional "ls" does.
11622 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11623 _AC_COMPILER_EXEEXT_O): Likewise.
11624 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11626 * bin/autoconf.as: Add --prepend-include option. This patch was
11627 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11628 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11630 * bin/autoconf.in, configure: Regenerate.
11632 * doc/autoconf.texi (Special Shell Variables): Mention
11633 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11635 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11636 MAILPATH and set PS1, PS2, PS4 to default values, to work
11637 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11638 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11639 the Autoconf documentation specifies; fall back to "unset" only if
11640 this fails. Use a shell for-loop for this rather than an m4 loop,
11641 to shorten the output script.
11643 2002-08-30 Paul Eggert <eggert@twinsun.com>
11645 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11646 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11647 for the CDPATH problem. Document PWD.
11648 (Limitations of Builtins): Document the problem that "cd $foo" and
11649 "ls $foo" may refer to different directories in shells conforming
11650 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11651 example, since the old example is now out of date.
11653 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11654 FOO" and "ls FOO" talk about different directories; this catches
11655 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11658 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11659 of rolling our own unset.
11660 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
11661 in practice we needn't worry about CDPATH if unset doesn't work.
11663 * Makefile.in, aclocal.m4, bin/Makefile.in,
11664 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
11665 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
11666 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
11667 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
11668 tests/Makefile.in: Regenerate with Automake 1.6.3.
11670 * config/config.guess, config/config.sub, config/mkinstalldirs:
11673 * configure: Regenerate with self.
11675 2002-08-30 Kevin Ryde <user42@zip.com.au>

11685 2002-08-29 Akim Demaille <akim@epita.fr>
11687 * lib/Autom4te/General.pm (&xqx): New.
11688 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11689 hand, which is not portable.
11691 * bin/autom4te.in: Use them.
11692 Use &error instead of die.
11693 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11696 2002-08-17 Paul Eggert <eggert@twinsun.com>
11698 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
11699 default list of compilers to try, since it was long ago superseded
11700 by the ksh fc builtin. Suggested by Steven G. Johnson.
11702 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
11704 * doc/autoconf.texi (Invoking autom4te): End the option table,
11705 fixing a bug introduced by the previous patch.
11706 (Limitations of Make): Add a 'target lookup' subentry in the
11707 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
11709 2002-07-29 Mark D. Roth <roth@feep.net>
11711 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
11712 options and use $AUTOM4TE_PATH.
11713 * doc/autoconf.texi: Remove documentation of autom4te
11714 --include-envvar and --site-macro-subdir options and document
11715 use of $AUTOM4TE_PATH.
11716 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
11717 arguments from each language section.
11719 2002-07-29 Paul Eggert <eggert@twinsun.com>
11721 * doc/install.texi: Include copyright symbol in copyright notice.
11723 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
11725 (AM_MAKEINFOFLAGS): New macro.
11726 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
11727 * Makefile.am (INSTALL): Use the new macros.
11728 Use -o rather than --output, since "missing" does not grok --output.
11730 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11732 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
11733 comments do not always work. Never trust the exit status of
11736 2002-07-24 Kevin Ryde <user42@zip.com.au>
11738 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
11739 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
11741 2002-07-23 Paul Eggert <eggert@twinsun.com>
11743 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
11744 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
11745 apparently treats PATH="nonexistent" as if it contained ".".
11746 Bug reported by Stefan `Sec' Zehl.
11748 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11750 * doc/autoconf.texi (Limitations of Make): Mention the special

11798 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
11799 latter was not run.

11962 if ln doesn't work.
11964 * doc/autoconf.texi (Configuration Links): Likewise.
11965 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
11967 2002-06-05 Paul Eggert <eggert@twinsun.com>
11969 * config/config.guess, config/config.sub, config/texinfo.tex:
11970 Update from masters.
11972 2002-05-29 Paul Eggert <eggert@twinsun.com>

11995 * NEWS, doc/autoconf.texi (Particular Types): Document it.
11996 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
11997 instead of AC_MBSTATE_T, which never existed.

12001 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
12002 version of Autoconf that is discussed.
12004 2002-05-22 Paul Eggert <eggert@twinsun.com>
12006 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
12007 from the default list of compilers to try. Suggested by
12009 * NEWS: Document the above.
12010 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
12012 2002-05-17 Paul Eggert <eggert@twinsun.com>
12014 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12015 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12016 This improves on an earlier suggestion by H. Peter Anvin.
12018 2002-05-16 Paul Eggert <eggert@twinsun.com>
12020 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12021 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12022 Both macros now accept an optional source-dir arg.
12023 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12025 * NEWS: Document this.
12026 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12028 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12029 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12030 not for GNU extensions; this undoes part of the 2000-11-03 change,
12031 reverting to 2.13-compatible behavior.
12032 Add new optional argument DIR.
12033 (AC_FUNC_FNMATCH_GNU): New macro.
12035 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12037 2002-05-08 Paul Eggert <eggert@twinsun.com>
12039 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12040 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12041 and it causes a 'test' syntax error if it fails.
12042 Bug reported by Stephen Gildea.
12044 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12045 If prototypes are supported, use them to check this at compile-time,
12046 instead of trying to check it at run-time. If we must do a run-time
12047 check, assume that setvbuf is standard when cross-compiling, as
12048 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12049 Bug reported by Paul D. Smith.
12051 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12052 argument specifying location of getloadavg.c. This removes a
12053 FIXME. This idea was taken from Jim Meyering's implementation in
12055 * doc/autoconf.texi (Particular Functions): Document this.
12056 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12057 that's what the code does; this fixes a bug reported by
12060 2002-05-03 Akim Demaille <akim@epita.fr>
12062 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12063 autopoint instead of gettextize.
12064 ($uses_alocal): Rename as...
12065 ($uses_aclocal): this.
12066 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12067 Suggested by Bruno Haible.
12069 2002-05-03 Akim Demaille <akim@epita.fr>
12071 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12073 2002-04-29 Paul Eggert <eggert@twinsun.com>
12075 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12076 files to be 1 second older; just set them to be the same time.
12077 Also, sleep 1 second after the first aclocal, to work around
12078 problems with sub-second time stamps on the input files.
12080 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12082 * doc/autoconf.texi: Mention "set -e -x" lossage
12083 under node "Limitations of Builtins".
12085 2002-04-29 Akim Demaille <akim@epita.fr>
12087 * doc/install.texi: Better wording for setting variables when
12089 From Christian Cornelssen.
12091 2002-04-29 Akim Demaille <akim@epita.fr>
12093 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12094 of lack of $LINENO support, then the test will compare the $LINENO
12095 in testsuite vs. the lineno in the test file. This is wrong, of
12097 Be sure to protect it.
12098 Reported by Patrick Welche.
12100 2002-04-25 Akim Demaille <akim@epita.fr>
12102 * doc/autoconf.texi (Obsolete Macros): Typo.
12103 Reported by Vladimir Volovich.
12105 2002-04-25 Akim Demaille <akim@epita.fr>
12107 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12108 than some of the input files, hence, on the second run of aclocal,
12109 if some of its input are younger, make them older.
12110 Suggested by Paul Eggert.
12112 2002-04-25 Akim Demaille <akim@epita.fr>
12114 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

12119 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12120 and ac_subst_vars be sh variables containing the list of
12121 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12123 (_AC_INIT_PREPARE): Use them to log them.
12124 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12125 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12126 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12127 _AC_SUBST_FILES and _AC_SUBST_VARS.
12128 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12130 2002-04-24 Akim Demaille <akim@epita.fr>
12132 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12133 autoheader, so that automake does not complain about a missing
12134 config.h.in that was to be created.
12136 2002-04-23 Akim Demaille <akim@epita.fr>
12138 * bin/autoheader.in (parse_args): --warning takes an argument.
12141 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
12143 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

12188 Minor spelling and grammar fixes.
12190 * doc/autoconf.texi: Follow the outline suggested in the GNU
12191 Sample Texts sections of the Texinfo 4.2 manual. Most
12192 importantly, this makes sure that the copyright notices appear in
12193 all output formats. You probably need Texinfo 4.2 to generate

12233 * doc/autoconf.texi (Shell Substitutions): Explain it.
12234 From Oliver Kiddle and Peter Stephenson.
12236 Have M4sh perform minimal shell sanitizing.
12238 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12240 (_AS_PREPARE): this new macro.

12245 Adjust Autoconf and Autotest.
12247 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12248 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12249 * lib/autotest/general.m4 (AT_INIT): Likewise.
12250 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
12251 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
12254 Use this M4sh to generate Autoconf's shell scripts.
12256 * tests/wrapsh.as: New, precursor of wrapsh.in.
12257 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12258 on Autotest and M4sh.
12259 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12260 (wrapsh.in): New target.

12276 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
12277 (Portable Shell): Cross reference to Systemology.
12279 2002-04-05 Akim Demaille <akim@epita.fr>
12281 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
12282 directories when descending in a SUBDIRS.
12283 Reported by Ezra Peisach.
12285 2002-04-04 Andreas Schwab <schwab@suse.de>
12287 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
12288 contains no literal separators.

12294 Use dnl, not the KILL diversion.
12296 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12297 (AC_CONFIG_LINKS): here.
12299 Don't use the KILL diversion, as it kills spurious output, which
12300 results in failures being hidden.
12301 Use m4_defn where appropriate.
12302 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12303 after the second argument.
12305 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12306 syntax, as it is provided by M4sugar.

12328 Integrate AC_PROG_CC_STDC into AC_PROG_CC.

12346 2002-03-28 Kevin Ryde <user42@zip.com.au>
12348 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12349 to avoid versions of HP C which don't allow that.
12351 2002-03-27 Paul Eggert <eggert@twinsun.com>
12353 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

12367 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12368 as POSIX requires, as it doesn't work with Zsh.
12369 * doc/autoconf.texi (Assignments): Document the problem.
12371 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12373 * doc/autoconf.texi (Limitations of Make): Mention more issue
12374 about VPATH, overriding of macros in sub-makes, and handling of
12377 2002-03-21 Paul Eggert <eggert@twinsun.com>
12379 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12380 problem with here-document buffer boundaries.
12382 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12383 when reinvoking the shell, to work around problems with installers
12384 who put strange things like "cd" commands in their environments.

12408 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12409 (Limitations of Usual Tools): Add mkdir section.
12411 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12412 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12413 back on AS_DIRNAME to compute prefixes otherwise; this is
12414 roughly what mkinstalldirs does. That way, we need not have
12415 our own filename disassembler. The old disassembler did not
12416 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12418 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12419 Create at_test_all by a series of assignments,
12420 not by a single assignment of a long string. The latter causes ksh
12421 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12422 presumably because of a buffer overrun.
12424 2002-03-14 Paul Eggert <eggert@twinsun.com>
12426 * lib/autotest/general.m4 (at_times_skip):
12427 Renamed from at_times. Now a boolean.
12428 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12429 says 'times: not found'.

12520 and host is irrelevant.

12522 backward compatibility hooks. Rather, collect them all into...
12523 (Hosts and Cross-Compilation): this new section.
12524 * doc/install.texi (System Type): Ditto.
12525 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state

12538 2002-03-04 Akim Demaille <akim@epita.fr>

12541 `foreach' loops immediately evaluate them.
12543 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12544 $*. This is the n-th time I change my mind, but hopefully this is
12547 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12549 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12550 it was only a hack for m4_text_wrap.
12551 (m4_car2): Remove, replaced by...
12553 (_m4_foreach): Adjust.
12554 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use

12715 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12716 AUTOTEST_PATH *after* it was set.
12717 Don't put `.' in the PATH: the user should be precise and `./' if
12718 needed. In addition, given that the test suite does some `cd', if
12719 `.' is in the path, the `tested programs' sections will report
12720 programs found in the test suite's directory, while during the
12721 tests (performed in their own directory), these programs are no
12722 longer visible. In other words, the results is confusing and

12799 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
12800 and PACKAGE_BUGREPORT from here...
12801 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
12803 (_AC_INIT_PREPARE): AC_DEFINE these symbols.

12946 This patch implements a `long double' suggestion by Oliver Kiddle.
12948 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
12949 static, to catch errors if the value isn't known at compile-time
12950 and the compiler supports dynamic arrays. Change its name from
12951 `_array_' to `test_array' to avoid potential name clashes.
12952 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
12953 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
12954 better than double. Catch a bug in GCC 2.95.2 x86.
12955 * doc/autoconf.texi (C Compiler): Document the above.
12958 2001-11-13 Akim Demaille <akim@epita.fr>
12960 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
12962 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
12964 2001-11-13 Akim Demaille <akim@epita.fr>
12966 * lib/autotest/general.m4 (AT_INIT): After having run the test
12967 group, go back to the initial directory, not to at_suite_dir.
12969 2001-11-13 Akim Demaille <akim@epita.fr>
12971 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
12972 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
12973 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
12975 (AT_CHECK_CONFIGURE): Use absolute paths.
12976 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
12977 The problem is still the old one: there is no means in M4 (that I
12978 know about) to create a defining macro, because there is no means
12979 to create `$1' etc., therefore, the defining macro ``swallows''
12980 all the arguments meant to the defined macro.
12982 2001-11-13 Akim Demaille <akim@epita.fr>
12984 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
12985 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
12987 * tests/aclocal.m4: Remove, as it is no longer used.
12989 2001-11-13 Akim Demaille <akim@epita.fr>
12991 * lib/autotest/general.m4: Change `tests?' into `groups?' in
12992 variable names when referring to a single test group, or to
12993 `suite' when referring to the whole test suite.
12994 `at_last_test' is removed: m4 compute at_format itself.
12995 (at_stdout, at_stder1, at_stderr): New variables.
12996 (AT_CHECK): Use them.
12998 2001-11-13 Akim Demaille <akim@epita.fr>
13000 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13002 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13003 Do it as soon as a test fails, don't wait till the end of the test
13005 Don't remove $as_me.[0-9]*, since these files no longer exist.
13007 2001-11-13 Akim Demaille <akim@epita.fr>
13009 * tests/tools.at: Use absolute paths, since we are no longer run
13012 2001-11-13 Akim Demaille <akim@epita.fr>
13014 Now that tests are running in their own private dir, there is no
13015 need to list the files to remove at the end of tests groups.
13017 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13018 (AT_data_files, at_data_files): Remove.
13019 (AT_CLEANUP, AT_DATA): Simplify.
13021 Remove the group dir if !debug && !failed.
13022 * tests/atspecific.m4: Adjust.
13024 2001-11-13 Akim Demaille <akim@epita.fr>
13026 Start a new layout for Autotest: `testsuite' creates
13027 `testsuite.dir' in which the at-check-line etc. files are to be
13028 found, and `testsuite.dir/003' where the test group 3 is run.
13030 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13031 at_check_line_file, at_format, at_test_normalized, at_group_dir
13033 Create the directories.
13034 Use absolute paths for at- files.
13035 (AT_CHECK): Adjust.
13037 2001-11-11 Michael Matz <matz@kde.org>
13039 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13041 (m4_car): Properly quote arguments.
13043 2001-11-13 Akim Demaille <akim@epita.fr>
13045 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13046 with stricter rules on LIBOBJS.
13048 2001-11-12 Paul Eggert <eggert@twinsun.com>
13050 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13051 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13054 2001-11-12 Akim Demaille <akim@epita.fr>
13056 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13058 2001-11-12 Akim Demaille <akim@epita.fr>
13060 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13061 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13062 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13063 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13064 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13065 specify to what the macro should be defined (typically to 1).
13067 2001-11-12 Akim Demaille <akim@epita.fr>
13069 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13072 2001-11-12 Akim Demaille <akim@epita.fr>
13074 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13075 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13076 definition used by Automake where LEX is +/- "${missing} lex" and
13077 `missing' itself contains variables.
13079 2001-11-12 Akim Demaille <akim@epita.fr>
13081 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13082 Now that M4sh pushes BODY, the comments were output at the end of
13085 2001-11-08 Akim Demaille <akim@epita.fr>
13087 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13088 that we can trace macros from aclocal.m4.
13089 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13090 obsoleted, and redirect to the former anyway.
13091 Reported by Ralf Corsepius.
13093 2001-11-08 Akim Demaille <akim@epita.fr>
13095 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13096 processed only if present.
13097 * tests/torture.at (Configuring subdirectories): Use autoreconf
13098 instead of successive calls to autoconf.
13099 Add a nonexistent subdirectory to exercise the patch above.
13100 Reported by Ralf Corsepius.
13102 2001-11-08 Kevin Ryde <user42@zip.com.au>
13104 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13105 doesn't accept .S files.
13107 2001-11-07 Akim Demaille <akim@epita.fr>
13109 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
13110 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
13111 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13112 * bin/autom4te.in (warn_forbidden): New.
13113 (handle_output): Use it.
13114 Read m4_pattern_forbid with messages.
13116 2001-11-05 Akim Demaille <akim@epita.fr>
13118 * bin/autom4te.in (--normalize): Remove.
13119 * lib/autom4te.in: Adjust.
13121 2001-11-05 Akim Demaille <akim@epita.fr>
13123 * tests/Makefile.am (testsuite): Rename this target as...
13124 ($(TESTSUITE)): this.
13127 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13129 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13130 the --prefix option, also remove it's argument.
13132 2001-11-05 Akim Demaille <akim@epita.fr>
13134 * doc/autoconf.texi (testsuite Invocation): Update.
13135 (Writing testsuite.at): Update.
13137 2001-11-03 Akim Demaille <akim@epita.fr>
13139 * doc/autoconf.texi: s/@code/@command/ where appropriate.
13141 2001-11-03 Akim Demaille <akim@epita.fr>
13143 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13144 (&file_name_is_absolute): New, wrappers around routines from
13146 Use and export them.
13147 (&find_configure_ac): Optionally take a directory where to look at.
13148 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13150 Default @ARGV to `.', not find_configure_ac.
13151 (&autoreconf): Argument is a directory.
13152 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13153 * doc/autoconf.texi (autoreconf Invocation): Update.
13155 2001-11-03 Akim Demaille <akim@epita.fr>
13157 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13158 (@export_forward_subs): New.
13159 Add basename, dirname, and fileparse.
13161 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13162 Don't look for aclocal flags if we already know aclocal is not
13164 Move aclocal.m4t only if it exists.
13165 Reported by Ezra Peisach.
13167 2001-11-03 Akim Demaille <akim@epita.fr>
13169 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13170 passed on command line, defaulting to ./configure.ac if present.
13171 (&maybe_autoreconf, File::Find): Remove, unused.
13172 (&autoreconf): If autoconf is not used, don't try to trace.
13174 2001-11-02 Akim Demaille <akim@epita.fr>
13176 * configure.ac: Bump to 2.52g.
13178 2001-11-02 Akim Demaille <akim@epita.fr>
13182 2001-11-02 Akim Demaille <akim@epita.fr>
13184 * config/config.guess, config/config.sub, doc/standards.texi:
13185 * config/lispdir.m4: Update from masters.
13186 * configure.ac: Bump to 2.52f.
13188 2001-11-02 Akim Demaille <akim@epita.fr>
13190 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13191 Don't run aclocal when aclocal.m4 is not from aclocal.
13193 Don't run libtoolize and gettextize if --install is not given.
13195 2001-11-01 Paul Eggert <eggert@twinsun.com>
13197 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13198 be invoked before _AS_LINENO_PREPARE.
13199 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13200 than character ranges.
13202 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13203 invoking AS_BASENAME. Set the locale variables to 'C' if
13204 possible, as POSIX requires this to get the traditional
13206 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13208 2001-10-31 Paul Eggert <eggert@twinsun.com>
13210 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13211 with {}, as that triggers a bug in Bash 2.05.
13213 (_AS_LINENO_PREPARE): Use Sed rather than
13214 Awk. Fix the sed prepass to work even if there are multiple
13215 instances of $LINENO on the same line. Do not substitute for
13216 other variables like $LINENOT. Do not check file dates; such a
13217 check is unreliable on sufficiently fast machines, and removing
13218 the check makes the code simpler and more reliable. Check for
13219 output and chmod failures.
13221 * doc/autoconf.texi (Special Shell Variables): Document
13224 2001-10-31 Akim Demaille <akim@epita.fr>
13226 * tests/Makefile.am (atconfig): Remove this target, Automake
13229 2001-10-31 Akim Demaille <akim@epita.fr>
13231 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13232 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13233 provided, while it is optional.
13234 * configure.ac: Adjust.
13236 2001-10-26 Paul Eggert <eggert@twinsun.com>
13238 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13239 lib/Autom4te/Struct.pm:
13240 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13243 * doc/autoconf.texi (Special Shell Variables): Document some
13244 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13246 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13247 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13248 eval $LINENO is not portable in practice.
13250 2001-10-24 Akim Demaille <akim@epita.fr>
13252 * lib/Autom4te/General.pm (backname): New.
13254 2001-10-24 Akim Demaille <akim@epita.fr>
13256 * m4/: Remove, merged into...
13259 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
13261 * doc/autoconf.texi (Shellology): Mention the problems with bash
13262 2.05's use of ANSI quoting in its `set' builtin.
13264 2001-10-22 Paul Eggert <eggert@twinsun.com>
13266 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13267 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13268 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13269 POSIX decided to standardize on the int flavor of strerror_r.
13270 Always do char* test, as there's no reason not to.
13271 Assign to a char* var, to catch strerror_r that returns int*.
13273 * doc/autoconf.texi (Particular Functions):
13274 Document the above changes. Also, document the fact that
13275 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13277 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13279 2001-10-20 Akim Demaille <akim@epita.fr>
13281 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

13284 2001-10-20 Akim Demaille <akim@epita.fr>
13286 * lib/Autom4te/General.pm (&update_file): If destination is
13287 unchanged, remove the source.
13288 (&up_to_date_p): Don't be verbose, be debug.
13289 * bin/autoreconf.in: No longer support --m4dir.
13290 (&autoreconf): Display the full path of the configure.ac we are
13292 Trace it only once.
13293 Be sure to honor --force with gettextize.
13294 Always run aclocal.
13295 * doc/autoconf.texi: Adjust.
13297 2001-10-20 Akim Demaille <akim@epita.fr>
13299 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13301 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13302 `intl' is already present, as it refuses unless --force.
13303 (&parse_args): Use -I, --include instead of the old Autoconf
13305 ($localdir, $autoconf_dir): Remove.
13307 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13309 2001-10-19 Jens Petersen <petersen@redhat.com>
13311 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

13321 2001-10-19 Akim Demaille <akim@epita.fr>
13323 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
13324 comment, explain how to install automatic mode selection.
13327 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
13329 * bin/autoreconf.in (autoreconf): Display the path to the
13330 configure.ac being studied.
13332 2001-10-18 Paul Eggert <eggert@twinsun.com>
13334 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13335 long, to work around a bug in the HP C compiler version HP92453-01
13338 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13339 (AS_BASENAME_EXPR): New macro.
13340 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13341 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13342 and fall back on 'sed' only if the other two fail. This makes
13343 AS_BASENAME act more like AS_DIRNAME.
13344 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13345 contains white space.
13346 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13347 Use AS_DIRNAME, since I think it's now DOS-friendly.
13348 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
13349 Allow "dirname //FOO" to return either / or //, as POSIX allows
13352 2001-10-10 Akim Demaille <akim@epita.fr>
13354 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

13360 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
13361 m4_define, since...

13453 M4sugar peer, i.e., drop the `AC_PROVIDE_$1' broken marker.
13455 2001-10-08 Akim Demaille <akim@epita.fr>
13457 Use `add-log-current-defun-function' for ChangeLog creation.
13458 Suggested by Tom Tromey.
13460 * lib/emacs/autotest-mode.el (autotest-mode-map): New.
13461 (autotest-mode): Adjust.
13462 * lib/emacs/autoconf-mode.el (autoconf-mode-map): Modernize, map

13489 shell does not support LINENO, and if CONFIG_SHELL is unset or
13490 empty, and if we can find a shell that does support LINENO,
13491 then set CONFIG_SHELL to that shell and then re-execute
13492 ourselves with CONFIG_SHELL.
13494 2001-10-05 Paul Eggert <eggert@twinsun.com>
13496 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
13497 doesn't exist. Remove *.tmp, as a .tmp file is created during the
13498 build of $(TESTSUITE).
13500 2001-10-05 Akim Demaille <akim@epita.fr>

13539 compatibility with POSIX shells.
13541 2001-10-02 Akim Demaille <akim@epita.fr>
13543 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
13544 instead of exec'ing to preserve $0 and $@.
13546 2001-10-01 Akim Demaille <akim@epita.fr>

13567 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
13568 Don't use nested parenthesization. This patch was originally

13570 but somehow it didn't get incorporated then.
13571 * doc/autoconf.texi (Limitations of Usual Tools):

13577 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13578 Check for `expr' arithmetic overflow, and for compilation failure,
13579 and invoke a new argument $4 if either is discovered.
13580 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13581 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
13583 2001-09-28 Akim Demaille <akim@epita.fr>
13585 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

13615 * tests/fortran.at (GNU Fortran 77): there.
13616 * doc/autoconf.texi (autoconf Invocation): Fix the example:
13617 AC_TRY_RUN is about compilation, not shell commands.
13618 (Test Programs): AC_TRY_RUN works as used to be advertised.

13631 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

13645 2001-09-23 Akim Demaille <akim@epita.fr>
13647 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
13648 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
13649 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
13650 builddir, buildpath, top_builddir, and top_buildpath.

13652 the current directory.
13653 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir

13655 Skip nonexistent dirs.
13656 * doc/autoconf.texi (Preset Output Variables): Document these
13659 * lib/autotest/general.m4: Do not reset AT_victims.
13660 Don't compute at_srcdir nor at_top_srcdir.
13662 * tests/tools.at: Hence use top_srcdir.
13664 * tests/Makefile.am, tests/autoconf, tests/autoheader,
13665 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
13667 * tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,

13677 * doc/autoconf.texi (Common Shell Constructs): Rename as...
13678 (Programming in M4sh): this.

13719 2001-09-22 Akim Demaille <akim@epita.fr>
13721 * lib/autoconf/autotest.m4: Create `package.m4'.
13722 * tests/Makefile.am (package.m4): Remove.
13724 2001-09-22 Akim Demaille <akim@epita.fr>
13726 Rely on `$LINENO' when possible instead of `__oline__'.
13728 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
13729 `$LINENO' support replacement when not supported.
13730 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

13734 * lib/autoconf/programs.m4: Replace all the occurrences of
13735 `__oline__' with `$LINENO'.
13736 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
13738 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
13740 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
13741 character (u: -> ue) in a code comment.
13742 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
13745 2001-09-21 Akim Demaille <akim@epita.fr>
13747 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
13748 Suggested by Jim Meyering.
13750 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13752 * lib/autoconf/programs.m4: Use extensions listed in
13753 $ac_executable_extensions when looking for programs.
13755 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13757 * lib/autoconf/general.m4: Fix a small Englisho.

13766 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
13767 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
13768 be used instead of ':'.
13769 * lib/autotest/general.m4: Replace occurrences of ':' in
13770 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
13772 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13774 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
13775 arguments. Fixed a typo.
13777 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13779 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
13780 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
13782 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13784 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
13785 * bin/autoupdate.in: Ditto.
13786 * bin/autoheader.in: Reworded a few comments.

13791 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13793 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
13794 already have $file). Set output files to binary mode (helps avoid
13795 CR issues on DOSish systems).
13797 2001-09-19 Akim Demaille <akim@epita.fr>
13799 * lib/autotest/general.m4: Englishoes.
13800 From Tim Van Holder and Alexey Mahotkin.
13802 2001-09-18 Paul Eggert <eggert@twinsun.com>
13804 * doc/autoconf.texi (Common Shell Constructs): New node,
13805 documenting AS_DIRNAME.
13806 (Limitations of Usual Tools): Refer to it when discussing dirname.
13807 Also, update discussion of POSIX standard to reflect latest draft.
13809 * lib/autoconf/c.m4:
13810 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
13812 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13813 Do not pass a first argument with leading '-'
13814 to expr, by parenthesizing initial integers that might be negative.
13816 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
13817 now merely checks whether it is an error to pass an argument
13820 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
13821 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
13822 whether it is a (compile-time) error to pass an argument to
13823 getpgrp. This simpler test supports the revised documentation,
13824 and is all that AC_FUNC_GETPGRP's users really need.
13826 2001-09-18 Akim Demaille <akim@epita.fr>
13828 * doc/autoconf.texi (Limitations of Make) <$<>: New.
13830 2001-09-18 Akim Demaille <akim@epita.fr>

13834 * lib/autotest/general.m4 (AT_INIT): Adjust.
13836 2001-09-18 Paul Wagland <paul@wagland.net>
13838 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
13840 Add test for AS_BASENAME.
13841 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
13842 added test. It now correctly handles /1/2/3/, returning '3' not ''.
13843 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
13844 * tests/base.at: Fixed the expected responses. The old ones were
13846 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
13847 the documentation claims it should (and how it behaved in 2.13).
13849 2001-09-18 Akim Demaille <akim@epita.fr>
13851 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
13852 the AC_CONFIG_COMMANDS invocation.
13853 This also solves the name clash problems.
13854 Don't set the package's ID.
13855 * lib/m4sugar/Makefile.am (version.m4): Revamp.
13856 No longer to be shipped.
13857 (version.in): Remove.
13858 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
13859 * lib/autoconf/status.m4: Adjust.
13860 Use `m4_PACKAGE_STRING'.
13861 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
13862 the only optional argument is the name of the test suite.
13863 Expect `package.m4' to define the package signature.
13864 * lib/autom4te.in (Autotest): Add `package.m4?'.
13865 * tests/Makefile.am (package.m4): New.
13866 * tests/suite.at: ifnames is a victim.
13868 2001-09-18 Akim Demaille <akim@epita.fr>
13870 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
13871 AC_LIBSOURCE, AC_CONFIG_FILES.
13872 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
13873 program version string doesn't match the package's.
13874 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
13877 2001-09-17 Paul Eggert <eggert@twinsun.com>
13879 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13880 Allow expression to return any value that can fit into unsigned long
13881 (not int, as before). Check for output errors.
13883 2001-09-17 Bruno Haible <haible@ilog.fr>
13885 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13886 Always include <stdio.h> and <stdlib.h>. Evaluate
13887 the expression in an extra function before these includes. Call
13888 fprintf "%d" only after ensuring the argument is of type 'int'.
13889 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
13891 2001-09-17 Paul Eggert <eggert@twinsun.com>
13893 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
13894 or CFLAGS=-O5. In that case, the linker has a relaxed view of
13895 fatal errors, and AC_CHECK_LIB causes it to include libraries even
13896 when they don't exist.
13898 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
13899 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't

14251 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14252 indeed related to running the test suite, while passing

14830 magic values from an object file when cross-compiling.
14831 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
14833 2001-08-10 Akim Demaille <akim@epita.fr>
14835 * bin/autom4te.in (&handle_output): Don't use `grep' with side
14837 Suggested by Russ Allbery.
14839 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
14841 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
14842 current $prefix to the sub-configures.
14844 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
14846 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
14847 extension (needed on BeOS). Reported by Guido van Rossum.
14849 2001-08-09 Akim Demaille <akim@epita.fr>
14851 * bin/autom4te.in ($icache): Load it only if older than autom4te.
14853 2001-08-07 Akim Demaille <akim@epita.fr>
14855 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
14857 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
14858 No need to remove the files before and after the each test, before
14859 each test and at the end of the suite is enough.
14860 Display only the children `times', not the shell's.
14861 If the test failed or was skipped, at-times is not available.
14863 2001-08-07 Akim Demaille <akim@epita.fr>
14865 Always produce testsuite.log, including when there are no
14866 failures. This helps getting information on skipped tests, and
14867 duration of the tests. Err, implement the latter btw.
14869 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
14870 Dump information on the first run of each test.
14871 (AT_CLEANUP): Create `at-times' containing the duration of the
14874 2001-08-07 Akim Demaille <akim@epita.fr>
14876 The use of `dumpstat' revealed that `len' was used although it
14877 should not. m4_text_wrap was using it, but in the Autoconf world
14878 where it is legal. Hence (i) test M4sh in its own world, not
14879 Autoconf's, and (ii), ahem, fix the bug :)
14881 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
14882 does not like `' instead of [].
14883 (AT_INIT): Forbid `^_?AT_'.
14884 And don't output such tokens.
14885 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
14886 `script.as', and `autom4te.cache'.
14887 Remove `empty' and `macro' which are no longer used.
14888 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
14889 * tests/m4sugar.at: Use it.
14890 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
14892 2001-08-07 Akim Demaille <akim@epita.fr>

14898 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.

14903 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
14905 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
14906 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
14907 (AC_F77_MAIN): Likewise.
14909 2001-08-04 Akim Demaille <akim@epita.fr>
14911 Don't rely on M4sugar outputting the patterns in files, since we
14912 might process the output _without_ running m4, hence without these
14915 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
14916 * bin/autom4te.in (@Request::includes): Remove, unused.
14917 (@Request::source): Rename as...
14918 (@Request::input): this.

14923 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
14925 2001-08-04 Akim Demaille <akim@epita.fr>
14927 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
14928 autoconf', i.e., in addition to caching traces, cache the output.
14930 * bin/autom4te.in (Request::cache): Rename as...
14931 (Request::id): this.
14932 ($cache, $icache, $tcache, $ocache): New.

14941 * bin/autom4te.in ($force): New.
14942 (&parse_args, &print_usage): -f, --force is a new option.
14943 (&handle_output): CPP directives might have spaces after `#'.
14944 (&parse_args): The first file only can be frozen.
14946 2001-08-04 Akim Demaille <akim@epita.fr>
14948 Don't let autom4te compute the `include' traces several times:
14949 first check that the trace cache file is up to date, and then
14950 compare its timestamp with that of the output.
14952 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
14953 the preamble. Don't require 5.005 as Autom4te::General does it,
14954 and better yet (use `use', not `require'!).
14955 * lib/Autom4te/Struct.pm: Rename the last occurrences of
14956 Class::Struct as Autom4te::Struct.
14957 * lib/Autom4te/General.pm (File::stat): Use it.
14958 (&mtime): New, export it.
14959 * bin/autom4te.in: Use it.
14960 Declare `$req' is invalid if it is outdated.
14961 Don't declare it valid before saving it if something went wrong.
14963 2001-08-04 Akim Demaille <akim@epita.fr>

14966 must be proposed to the users.

15011 (m4_divert_pop): Dump the whole diversion stack when a diversion
15013 * bin/autom4te.in (&handle_output): Remember of the first
15014 occurrence of a possibly undefined macro, not the last.

15016 the appear in the output.

15018 * tests/tools.at (autoconf: forbidden tokens, basic)
15019 (autoconf: forbidden tokens, exceptions): No longer sort
15020 autoconf's stderr, as it is now deterministic.
15021 Check that `dnl' is caught.

15044 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
15045 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
