554 that preceeds @dots. Improve wording.
555 (Text processing Macros): Drop `1' suffix from metasyntax variable
556 name that preceeds @dots.

591 Cover more potentially problemtic file names. Use the new
594 Properly handle funny file names for headers in config.status.
595 The test suite did not cover this bug because the code was not
596 quoting properly the arguments of `rm -f' (which "fails" silently)
597 as well as the arguments of `diff' (whose output was redirected to
598 /dev/null so we couldn't see its error message).
599 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
600 file names passed to `rm' and `diff'.
601 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

706 BSD behavior on binary input.
708 Minor testsuite improvements.
709 * lib/autotest/general.m4 (AT_INIT) <PREPARE_TESTS>: Use fewer
710 forks when sanitizing PATH. Always output machine information,
711 not just when atconfig was located.
713 Add 'testsuite -C dir'.
714 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
716 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
718 <DEFAULTS>: Delay computation of variables based on $at_dir...
719 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
720 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
721 <PARSE_ARGS>: Parse new option.
722 <HELP_TUNING>: Document it.
723 * tests/autotest.at (Choosing where testsuite is run): New test

732 build-aux/texinfo.tex: Sync from gnulib.
733 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
736 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
738 * doc/autoconf.texi (Particular Programs): Do not mention the
739 Autoconf version in which the AC_PROG_INSTALL change was done.
740 Suggested by Paul Eggert.
742 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
744 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
745 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
746 mode, we change to the source directory, also set $ac_pwd so we
747 do not go back to the build tree for the next config subdir.

782 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
783 check_SCRIPTS. Building the wrappers for `all' allows help2man
784 to use them for the manpages.
785 Report by Benoit Sigoure.

803 (m4_require): Use m4_do, not m4_join.
805 Fix some whitespace tests on cygwin.
806 * tests/tools.at (autom4te and whitespace in file names): Restore
807 font-lock. Create $TMPDIR before it might be used.
809 Fix spurious testsuite failure with M4 1.4.11.
810 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
813 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
814 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
815 (m4_require): Avoid extra macro calls.
817 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
819 * tests/torture.at (srcdir): Fix quoting.
821 Do not pass top_srcdir to configure scripts in testsuite.
822 * tests/autotest.at (srcdir propagation): Copy install-sh to
824 (my only test): Drop setting of `top_srcdir'.
825 * tests/base.at (Input/Output): Likewise.
826 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
827 config.guess, and config.sub to test source tree.
828 Drop AC_CONFIG_AUX_DIR setting.
829 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
830 * tests/torture.at (Substitute a 2000-byte string): Drop
831 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
832 (Substitute a newline, datarootdir workaround): Likewise.
833 (Define a newline): Adjust for linenumber changes in configure.ac.
834 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
836 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
837 if `pwd` contains whitespace.
839 Quote $abs_top_srcdir in tests.
840 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
841 * tests/tools.at (Syntax of the shell scripts): Likewise.
843 * tests/m4sh.at (LINENO): Quote $0.
845 Fix testsuite program wrapper for whitespace in `pwd`.
846 The problem here is that the usual mantra is that command
847 variables can contain arguments, thus we cannot just escape
848 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
849 $top_builddir/tests directory early in $PATH, so that the
850 wrappers are found by their plain name.
851 * tests/wrapper.as: Put $testdir early in $PATH.
852 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
854 Proper config.status --file/--header and $srcdir escaping.
855 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
856 characters in $ac_file_inputs.
857 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs

860 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
862 Fix Autotest for whitespace in `pwd`.
863 * lib/autotest/general.m4 (AT_INIT)
864 <at_func_create_debugging_script, Driver Loop>:
866 * tests/autotest.at (whitespace in absolute testdir): New test.
868 * lib/autom4te.in: Quote @datadir@.
870 Proper file name escaping in Autoconf programs and Perl modules.
871 This includes escaping of characters special to the shell
872 as well as special to Perl, e.g., leading `<' or `>'.
873 For example, when $file starts with `>', `open ">$file"'
874 wrongly tries to append to a different file.
875 * bin/autoconf.as: Fix quoting for autom4te options.
876 * lib/Autom4te/General.pm (shell_quote): New function, taken
877 from coreutils, written by Jim Meyering.
879 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
881 * bin/autoreconf.in (parse_args): Likewise.
882 * bin/autoscan.in (main): Likewise.
883 * bin/autoupdate.in (main): Likewise.
884 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
885 * bin/ifnames.in: Likewise, XFile usage fixes.
886 * tests/tools.at (autom4te and whitespace in file names): Extend
887 test. Test twice, with special characters allowed on w32, and the
888 rest. Test leading and trailing whitespace, for `open_quote'.
889 (autotools and whitespace in file names): New, analogous test.
890 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
891 by Russ Allbery and Eric Blake.
894 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
895 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
896 * lib/Autom4te/FileUtils.pm (open_quote): New function.
897 (update_file, contents): Use it.
899 * Makefile.am (autom4te-update): Rewrite for git.
901 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
903 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
906 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
907 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
909 2007-12-04 Eric Blake <ebb9@byu.net>
911 Manually resync with gnulib, since 'make cvs-update' no longer works.
912 * build-aux/config.guess: New upstream version.
913 * build-aux/config.sub: Likewise.
915 When using older automake, don't downgrade build-aux/texinfo.tex.
916 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
917 * doc/Makefile.am (TEXINFO_TEX): Add.
919 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
921 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
922 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
923 #undef as this runs afoul of our new way of creating config.h.
924 Problem reported by Jim Meyering in
925 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
927 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
929 Fix autom4te for unusual characters in input file names.
930 * bin/autom4te.in (files_to_options): Quote active characters
932 * tests/tools.at (autom4te and white space in file names):
935 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
936 Document that Tru64 awk always splits $0.
938 2007-11-24 Stepan Kasal <kasal@ucw.cz>
940 * lib/autotest/general.m4 (AT_INIT): Do not extract the
941 `#AT_STOP_...' line at the end of each test.
943 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
945 * lib/autotest/general.m4 (AT_INIT): For awk line number
946 extraction script, ensure `$at_group' has a defined value
947 even for the empty set, and properly quote its usage inside
950 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
952 * doc/autoconf.texi (Shell Functions): New chapter. Document
953 IRIX sh $0 issue in functions, move content from ...
954 (Portable Shell): ... here.
955 (Shell Script Compiler): Note that shell functions are not
956 totally unportable any more.
958 2007-11-22 Stepan Kasal <kasal@ucw.cz>
959 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
961 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
962 extracting the line numbers of the last needed test.
964 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
966 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
969 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
971 Fix IRIX testsuite debugging failures: $0 in functions.
972 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
973 Do not use $0 inside a function, as IRIX sh will set that to the
974 function name rather than the script invocation name.
976 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
977 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
979 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
980 to extract test scripts.
981 (AT_INIT): Extract and cache test script line numbers.
983 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
985 * lib/autotest/general.m4: Revert 2007-11-15 patch and
986 subsequent fixups; the awk -> here-document conversion trashes
987 performance too much with AIX sh.
989 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
991 * tests/local.at: Do not test m4, perl with AT_TESTED.
993 Diagnose and guard against write errors dealing with config.status.
994 The general idea is this: all write failures from `configure'
995 writing `config.status' are indicated by $ac_write_error, which
996 is only checked at the end. This is safe because config.status
997 code is not executed before the file is complete. Other write
998 failures, be they inside config.status, or in sub shell/awk
999 scripts spawned from configure or config.status, typically need
1000 earlier checking, as their results are used right afterwards.
1001 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1002 before writing config.status, check afterwards.
1003 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1004 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1005 Set `ac_write_error' for write failures to config.status. Barf
1006 upon write failures to temporary files.
1007 Adjust note about closing and reopening the here-document.
1008 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1009 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1010 reopening the here-document.
1011 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1012 Ensure `ac_write_error' does not escape into config.status.
1013 Also, add a couple of code paths not yet exercised in the test
1014 suite: a config file with input from stdin, and a config header
1016 Suggestion for catching write errors by Bruno Haible.
1018 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1020 Avoid error with Tru64 awk and testsuite lines with many words.
1021 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1022 reads the testsuite, set the field separator to an unusual value,
1023 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1024 even splits the input if $i, i>0, was never accessed in the script.
1026 Revert 2007-10-17 change.
1027 * TODO: Multiline args in config files and headers mean something
1028 different and are not fixed, see

1042 Diagnose write errors in config.status instantiations.
1043 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)

1046 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

1065 * lib/autotest/general.m4 (at_func_test): Remove.
1066 (AT_INIT): Pre-extract test groups into separate files.
1067 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
1068 Remove at-test-source files together with the $at_group_dir.
1069 * tests/autotest.at (Long test source lines): New test.
1071 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1073 Shell functions and variables may share a namespace.
1074 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
1077 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
1079 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
1082 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1084 * lib/autoconf/status.m4: Fix a couple of comment typos.
1086 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1088 2007-11-13 Jim Meyering <meyering@redhat.com>
1090 Clean up the rule to create "expr".
1091 * tests/Makefile.am (expr): Don't redirect directly to target.
1092 Redirect just once, not for each echo statement.
1093 Use $@, not literal "expr".
1095 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1097 Don't worry about preprocessor when testing long long.
1098 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1099 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1100 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1101 These no longer check for preprocessor flaws.
1102 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1103 Do not check for preprocessor flaws.
1105 2007-11-13 Jim Meyering <meyering@redhat.com>
1107 Adapt dependencies, now that a version change doesn't modify configure.ac
1108 * GNUmakefile: Remove "make clean" kludge.
1109 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1111 Don't redirect directly to target.
1112 Use $@, not literal "version.m4".
1114 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1116 * doc/autoconf.texi (Making testsuite Scripts): Document
1117 ":;{" shorthand as in previous patch.
1119 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1121 * doc/autoconf.texi (Limitations of Builtins): Document problem
1122 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1124 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1125 Use ":;{" shorthand.
1126 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1128 2007-11-12 Jim Meyering <meyering@redhat.com>
1130 Add more non-srcdir build support.
1131 * GNUmakefile (dummy): Split a long line.
1132 Add -v option to autoreconf invocation.
1134 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1135 * GNUmakefile (dummy): Remove INSTALL.
1137 Remove racy commands to build scripts in bin/ and tests/.
1138 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1139 are guaranteed to be built, remove the rules that tried to build
1140 them. Before, with a parallel build, these rules could lead to
1141 two processes writing tests/wrapper.in concurrently.
1143 Build in man/ only *after* building in bin/ and tests/.
1144 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1145 in both bin/ and tests/.
1147 Accommodate non-srcdir build-from-checkout.
1148 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1149 Use git's --git-dir=$srcdir/.git option.
1150 Add quotes, in case tarball_version_file contains shell meta-characters.
1151 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1152 * configure.ac: Pass "." to git-version-gen.
1154 Avoid spurious test failures due to version skew.
1155 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1157 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1159 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1160 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1161 Remove conftest.dSYM directory.
1162 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1163 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1164 Remove `conftest.*' recursively.
1165 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
1166 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1168 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
1170 Report and analysis by Jeff Squyres and Peter O'Gorman.
1172 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
1174 Fix typos in variable names.
1175 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
1177 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
1179 Document that $((expression)) is not portable.
1180 * doc/autoconf.texi (Shell Substitutions): Here.
1182 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1184 Ignore configure --help* errors due to LINENO-impaired shells.
1185 * tests/torture.at (Configuring subdirectories, Deep Package):
1186 In the --help* tests in read-only trees, make `.' temporarily
1187 writable again for the `stderr' file, and ignore errors due to
1188 the attempt to write configure.lineno.
1189 Report by Patrick Welche.
1191 2007-11-10 Jim Meyering <meyering@redhat.com>
1193 Generate package.m4 in build-dir, not srcdir.
1194 * tests/Makefile.am (package.m4): Adjust target.
1195 Don't redirect directly to $@.
1196 (CLEANFILES): Add package.m4.
1197 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1199 When running $(AUTOTEST), search "." before searching $(srcdir).
1201 Avoid a race condition that would make parallel "distclean" fail.
1202 * tests/Makefile.am (distclean-generic): Replace the default,
1203 automake-provided rule with an identical one, but with an additional
1204 dependency on distclean-local. Simply adding the dependency would
1205 cause automake not to emit the rule at all.
1206 * BUGS: Building with -jN works, now.
1208 Distribute git-version-gen.
1209 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1210 since GNUmakefile is distributed, and requires it for dist* rules.
1212 Remove two more generated files from version control.
1213 * INSTALL: Remove generated file.
1214 * lib/autoscan/autoscan.list: Remove generated file.
1216 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1218 * GNUmakefile (PATH): Remove stray apostrophes; they become
1219 part of PATH, which isn't wanted here.
1221 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1223 New config files output variable `top_build_prefix'.
1224 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1226 * doc/autoconf.texi (Preset Output Variables): Document it.
1228 Report by Bob Friesenhahn.
1230 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1231 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1232 function, to parametrize arithmetic with expr vs. the shell.
1233 Use it where possible.
1234 Suggestion by Benoit Sigoure.
1236 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1238 Adjust the documentation of autotest WRT atlocal.
1239 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1240 when using Automake, to write a rule to produce atlocal, since it's
1241 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1242 distributed, not atconfig.in.
1244 2007-11-04 Eric Blake <ebb9@byu.net>
1246 Update list information.
1247 * README: Mention new autoconf-commit list.
1248 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
1250 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1252 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
1254 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1256 * build-aux/.gitignore: Ignore mkinstalldirs.
1258 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1260 2007-11-03 Jim Meyering <meyering@redhat.com>
1262 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1263 * build-aux/git-version-gen: This syncs from coreutils.
1265 Adjust the build procedure so "make check" works reliably.
1266 * README-hacking: Include an extra step between "make" and
1267 "make check" to ensure that the latter passes.
1269 Use just-built tools, when possible.
1270 * GNUmakefile (PATH): Set and export here, ...
1271 (dummy): ... rather than here.
1273 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1274 and Andreas Schwab <schwab@suse.de>
1276 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
1279 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1281 * configure.ac (AC_PREREQ): Require version 2.60, for
1282 AC_PROG_SED, AC_PROG_GREP.
1284 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
1285 and Jim Meyering <meyering@redhat.com>
1286 and Andreas Schwab <schwab@suse.de>
1287 and Eric Blake <ebb9@byu.net>
1289 Document a bug in GNU Bash with compound commands and redirections.
1290 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
1291 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
1294 2007-11-03 Eric Blake <ebb9@byu.net>
1296 Support m4 1.4.5 in testsuite.
1297 * tests/torture.at (Define a newline): Exclude line numbers in
1299 Reported by Ralf Wildenhues.
1301 2007-11-03 Jim Meyering <meyering@redhat.com>
1303 Remove automake-provided files from version control.
1304 * build-aux/elisp-comp: Remove file.
1305 * build-aux/install-sh: Remove file.
1306 * build-aux/missing: Remove file.
1307 * build-aux/mdate-sh: Remove file.
1308 * build-aux/.gitignore: New file.
1309 Suggestion from Ralf Wildenhues.
1311 2007-11-03 Eric Blake <ebb9@byu.net>
1313 Adjust version comparison to account for git snapshot numbers.
1314 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
1315 component separator.
1316 * doc/autoconf.texi (Number processing Macros)
1317 <m4_version_compare>: Document this change.
1318 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
1320 2007-10-30 Bruno Haible <bruno@clisp.org>
1322 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1323 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1324 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1325 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1326 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1327 Suggested by Paul Eggert.
1329 2007-10-28 Jim Meyering <meyering@redhat.com>
1331 * README-hacking: Autoconf, Automake, and Perl are required to build.
1332 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1334 2007-10-28 Jim Meyering <meyering@redhat.com>
1336 README-hacking: Recommend running autoreconf -vi.
1337 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1338 so that we use just-built tools when they're available.
1339 Suggestions from Ralf Wildenhues.
1341 2007-10-28 Jim Meyering <meyering@redhat.com>
1343 Make inter-release --version output more useful.
1345 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1346 which indicates that it is built using the 19th change set
1347 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1348 is a prefix of the commit SHA1.
1349 * build-aux/git-version-gen: New file.
1350 * configure.ac: Run it to set the version.
1351 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1352 * Makefile.am (dist-hook): Arrange so that .version appears only
1353 in distribution tarballs, never in a checked-out repository.
1354 * .gitignore: Add .version here, too. Just in case.
1355 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1356 not configure.ac, now that the version number changes automatically.
1358 Ensure that $(VERSION) is up to date for dist-related targets.
1359 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1360 git-version-gen doesn't match $(VERSION), but only for dist targets.
1362 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1364 Fix `Deep Package' failure with a configure script early in PATH
1365 * tests/torture.at (Deep Package): Add `.' early in PATH.
1366 Report by Jim Meyering.

1379 Improve corner case of m4_expand.
1380 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more

1383 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
1386 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>
1388 * doc/make-stds.texi: Update from gnulib.
1390 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1391 and Eric Blake <ebb9@byu.net>
1393 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
1394 problem reported by Bruno Haible in
1395 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
1397 2007-10-22 Eric Blake <ebb9@byu.net>
1399 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
1402 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1404 Don't check for bug in HP-UX 11.00 cpp.
1405 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
1406 Use -1ull rather than -1u, since that causes problems with gnulib; see
1407 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
1409 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1425 escaping of backslash in here-documents.
1427 Fix `Deep Package' test failure on FreeBSD.

1429 unnecessarily. Do not try running `/bin/sh configure' with a
1430 configure script to be found in $PATH, if the shell does not do
1431 this resolution. Fixes test failure on FreeBSD.
1433 Fix config header generation with AIX awk.
1434 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
1435 script, use helper array D_is_set, as `" 0"' does not evaluate
1436 to true for AIX awk.
1438 2007-10-21 Eric Blake <ebb9@byu.net>

1473 * lib/autotest/general.m4 (BANNERS): New named diversion.
1474 (TESTS_END): Diversion no longer used.
1475 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
1476 shell function, which prints only as needed, using an associative
1477 array of banner text from a special diversion.
1478 <PARSE_ARGS_END>: No longer need awk to find banners.
1479 <TESTS>: Banners are no longer processed by main driver loop, so
1480 we no longer need case statement.
1481 (AT_BANNER): Rewrite to populate new diversion.
1482 (AT_SETUP): Each test invokes its own banner. No output is needed
1483 to the TESTS diversion.

1510 duplication bug by using new macro.
1511 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
1512 programs with stdin redirected, so programs that don't
1513 understand --version won't try to behave interactively.
1514 * tests/autotest.at (Tested programs): Catch this bug.
1515 * tests/m4sugar.at (m4@&t@_append): Test new macro.

2576 renamed to "autoconf-invocation"
2578 * doc/autoconf.texi (Caching Results): The CACHE-ID variable
2579 in the examples should not use the internal "ac_" prefix.

2597 2007-05-01 Kevin Ryde <user42@zip.com.au>
2599 * doc/autoconf.texi (Particular Programs): Typo
2600 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
2602 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
2604 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
2605 'configure' will fail if the shell lacks proper support for shell
2606 functions. Suggested by RMS.
2608 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
2610 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
2611 about Solaris /bin/printf '%010000x' 123. Problem reported by
2614 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
2616 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
2617 for a.* when searching for executables, as this prevents users
2618 from having files like a.c. Problem reported by Ralf Wildenhues in:

2630 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
2631 AC_CHECK_TYPE, AC_CHECK_TYPES.
2632 * doc/autoconf.texi (Generic types): C types must be type-names
2633 (the C terminology), not type-ids (the C++ term). C++ types
2634 must not be anonymous.
2635 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
2636 for C++; this drops support for anonymous struct and union types,
2637 which were problematic anyway.
2638 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
2641 2007-04-12 Jim Meyering <jim@meyering.net>

2653 * doc/autoconf.texi (Generic Types): Document the restrictions
2654 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
2655 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
2656 with objects too. Document the restrictions on its use.
2657 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
2658 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
2659 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
2660 works but the latter doesn't, then it's a valid type.
2661 This lets people use function types and so forth.
2662 For C++ there doesn't seem to be a simple solution, so leave it alone.
2663 (AC_CHECK_SIZEOF): Allow argument to be a variable.
2664 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
2665 AC_CHECK_TYPE; that wasn't documented or necessary.
2667 2007-04-11 Stepan Kasal <kasal@ucw.cz>
2669 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
2670 when cross-compiling.

2690 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
2691 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
2692 default still has the problem. Problem reported by Bruce Korb.

2713 checks for unsigned long long int.
2715 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
2717 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
2718 nonstandard grep R.E. escape sequences.
2720 2007-03-17 Jim Meyering <jim@meyering.net>
2722 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
2723 (Limitations of Usual Tools): Also list \< and \>, and mention that
2724 HP-UX's grep, like the one from Solaris, does not support that syntax.
2726 2007-03-09 Stepan Kasal <kasal@ucw.cz>
2728 * doc/autoconf.texi (Specifying Names): `--host' does not
2729 change the build type.

2766 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
2767 status of rm so we know when it failed.
2768 If cleaning of test dir failed before running the test, warn.
2769 Output the line separator in verbose mode before the warning
2770 to make clear the warning belongs to the following test.

2835 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
2836 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
2837 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
2838 substitution will still be done by the special code.

2862 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
2863 early on the reader side, drop stderr of the input to avoid
2864 `broken pipe' error output; this may happen even with shell
2865 builtin `echo' of some bash versions. Reports by Ian Macdonald
2866 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
2868 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2883 discussion about the allow_superuser_privileges example,
2884 and change it a bit to make things clearer.
2885 (Optimization and Wraparound): Clarify whether the compiler
2886 will generate an infinite loop for the example derived from
2887 Autoconf's mktime test.
2888 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
2889 Also, clarify unsigned multiplication overflow.
2891 2007-01-04 Eric Blake <ebb9@byu.net>
2893 * bin/Makefile.am (RELEASE_YEAR): New macro.

2905 * doc/autoconf.texi (Integer Overflow): Revised based on today's
2906 feedback. The most important changes document what happens when
2907 you convert an out-of-range value to a signed integer type, and
2908 say that (sum < a) != (b < 0) reliably detects overflow when sum =
2911 * doc/autoconf.texi (Integer Overflow): Greatly expand and
2912 rewrite, taking notions from the recent discussion on the gcc and
2913 autoconf mailing lists; please see
2914 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
2915 and follow the many links.

2918 (Signed Integer Division): New sections.
2920 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
2922 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
2923 preprocessor macro arguments in traced name.
2924 * doc/autoconf.texi (Defining symbols): Document longstanding
2925 support for AC_DEFINE-ing macros with arguments, and document
2926 behavior when the same variable has multiple AC_DEFINEs.
2927 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
2928 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
2929 macros directly, giving much shorter and simpler code.
2931 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
2933 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
2934 space before "$ac_configure_args" to prevent a 'config.status
2935 --recheck' failure if ac_configure_args doesn't contain a leading
2936 space. This works around a problem with the XEmacs configure.ac,
2937 which uses the (undocumented) ac_configure_args variable
2938 inconsistently with Autoconf.
2940 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
2942 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
2943 Include <limits.h>, and use its INT_MAX to rewrite the
2944 j loop so that it does not overflow 'int'. Problem reported by
2946 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
2947 Play it safe by shifting left by 1 rather than multiplying by 2,
2948 as GCC is less likely to optimize this away when the value
2949 is signed (when it assumes overflow leads to undefined behavior).
2950 Also, don't assume time_t uses two's complement.
2952 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2954 * tests/torture.at (Substitute a 2000-byte string): Avoid using
2955 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
2956 dumps core on it. Report by Tim Rice.

2975 (External Software, Package Options): Cross-reference to Option
2976 Checking, and use this to shorten our section.
2977 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
2978 "$x" to test "x$foo" != x.

2980 Don't warn if $enable_option_checking is "no".
2981 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
2982 ac_unrecognized_opts to the empty string.
2983 Don't echo the unrecognized opts, as this might mishandle
2984 backslashes or leading -.

2986 usage next to the other --disable-FEATURE options in the

2991 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):

2994 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
2995 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
2996 Disable option checking when subdirs are configured.

2998 unrecognized --with and --enable options at the end of
2999 the configure output (as well as at the beginning).
3000 * doc/autoconf.texi (Option Checking): New node.
3001 Document new option warning functionality.

3010 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3011 Define HAVE_GETMNTENT to 1, not to the empty string.
3012 Problem originally reported by Jochen Friedrich in
3013 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3015 This change prompted by a problem report by Andrey Simonenko in
3016 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3017 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3018 object-like macros only, in the traditional portable character
3020 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3021 Warn about attempts to define things that are not identifiers.
3022 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3023 awful hack that AC_DEFINEd macro names containing parentheses.

3027 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3028 too drastic, even if Texinfo in theory requires it for info mode.
3030 (config.status Invocation): Renamed back from Recreating a
3032 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3033 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3035 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3037 * NEWS: Version 2.61a.
3039 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3040 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3042 * NEWS: Document changes with echo and printf, and the lack
3043 of limits on the total size of multi-line values of substituted
3044 variables, and the AC_FUNC_FSEEKO fix.
3046 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3048 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3049 Writing configure.ac.
3050 (Autoconf Input Layout): Renamed from configure.ac Layout.
3051 (Recreating a Configuration): Renamed from config.status Invocation.
3052 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3053 (acconfig Header): Renamed from acconfig.h.
3054 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3055 (Writing Testsuites): Renamed from Writing testsuite.at.
3056 (Autom4te Cache): Renamed from autom4te.cache.
3058 * BUGS: Remove mention of VPATH problem, since it's now documented
3059 not to be a bug in the Autoconf build procedure itself, but rather
3060 a problem with the proprietary `make' programs.
3062 * doc/autoconf.texi (Build Directories): Add a cross reference
3065 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3066 * doc/standards.texi: Sync from gnulib.
3068 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3069 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3070 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3071 generated automatically.
3073 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3075 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3076 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3077 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3079 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3081 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3082 `CEOF$ac_eof' special marker, the awk script cannot contain a
3083 line matching `^CEOF', so this is not needed any more.
3084 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3085 special marker in the test.
3087 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3089 * tests/tools.at (autom4te preselections): Use `find -newer';
3090 remove one of the sleeps.
3092 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3093 more readable, using ...
3094 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3096 * doc/autoconf.texi (autoheader Invocation): Do not double-
3097 quote the parameter of `AH_BOTTOM' in the example.
3099 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3101 * doc/autoconf.texi (Configuration Headers): Remove the
3102 example with multiple input files.
3103 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3104 multiple input files.
3106 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3108 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3109 creating the awk substitution script, handle one input line at a
3110 time, so that the maximum length of a substituted (multi-line)
3111 value is not limited by the size of the sed pattern space.
3112 The trade-off is a slightly repetitive sed script.
3113 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3114 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3115 * tests/torture.at (Substitute a 2000-byte string): Increase the
3116 test with several long lines, they should not be caught by sed
3119 * tests/tools.at (autom4te preselections): New test, to flag
3120 entries missing from autom4te.cfg.
3121 Report by David Byron <dbyron@hheld.com>.
3123 * tests/torture.at (Substitute a 2000-byte string): Actually use
3124 AC_PROG_AWK, so the last change works as intended.
3125 (Substitute and define special characters): Likewise.
3126 (Substitute a newline): Likewise.
3128 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3129 instead of `awk' consistently.
3130 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3131 * tests/torture.at (Torturing config.status): Test both the
3132 result of AC_PROG_AWK and plain awk.
3133 (Substitute a 2000-byte string): Likewise.
3134 (Substitute and define special characters): Likewise.
3135 (Substitute a newline): Likewise.
3137 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3139 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3140 can be assigned to a function pointer. Problem reported by
3141 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3142 part of a patch by Ralf Wildenhues in that same bug report.
3144 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3146 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3147 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3149 2006-12-01 Eric Blake <ebb9@byu.net>
3151 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3152 cross-compiling from cygwin to mingw.
3153 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3154 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3155 to lib/autoconf/c.m4.
3157 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3159 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3160 string for more reliable failure. Wrap the entire test that
3161 causes the broken Solaris printf to dump core, in a subshell,
3162 so the segmentation fault message is reliably suppressed.
3163 Fix shell expansion errors by using /usr/ucb/echo always;
3164 avoid an error on systems without it by another subshell.
3165 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3166 subshell-$as_echo to `as_echo', for better error message.
3168 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3170 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3171 `BASH_SOURCE' contain a newline, set them to empty, as they may
3174 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3176 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3177 years and is too hard to maintain now. The last straw was
3178 reported by Jerker Baeck in
3179 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3180 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3181 * doc/autoconf.texi (Particular Functions): Move
3182 AC_FUNC_SETVBUF_REVERSED from here...
3183 (Obsolete Macros): ... to here. Say that it does nothing now.
3184 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3185 Turn into (almost) a no-op.
3187 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3189 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3190 These macros are obsolescent and new applications shouldn't need them.
3191 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3192 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

3194 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3195 (AC_FUNC_VPRINTF): Likewise.
3196 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3197 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3198 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3200 * doc/autoconf.texi (Setting Output Variables): Mention that
3201 @VAR1@VAR2 has unspecified behavior. Problem reported by
3203 * NEWS: Mention this.
3205 * Makefile.am: Put only a single '#' into the copyright notice,
3206 so that it's also present in the output file. Standardize wording
3207 in makefile copyright notices to match GNU coding standards.
3208 * bin/Makefile.am: Likewise.

3221 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3223 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3224 in the sed script that mangles the awk script: delete up to the
3225 first exclamation mark only.
3226 * tests/torture.at (Substitute and define special characters):
3229 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3231 Rewrite config files generation: avoid quadratic growth in
3232 the number of substituted variables by using awk instead of sed
3233 for the bulk of the substitutions.
3234 * NEWS: Mention this.
3235 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3236 forbidden in the output (and thus input) file.
3237 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3238 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3239 generate just one large awk script for substitutions,
3240 eliminating much of the earlier complexity, while adding some
3241 new complexity. Only expand the substitution templates at
3242 configure time, for smaller configure script size. If
3243 _AC_SUBST_FILES are used, test 'awk' for working getline support
3244 at config.status time. If absent, interpolate through the
3245 shell. The awk script was written with much help
3246 from Paolo Bonzini and Paul Eggert.
3247 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3248 (_AC_SED_FRAG_NUM): Likewise.
3249 (_AC_SUBST_CMDS): Renamed from...
3250 (_AC_SED_CMDS): ...this.
3251 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3252 * tests/torture.at (Substitute a 2000-byte string): Also
3253 substitute a line with 1000 words, and a variable with several
3255 (Substitute and define special characters): Test awk special
3256 characters, and put substitution input strings `@foo@' in the
3257 output, to test that no recursion happens; test several other
3258 combinations from Paolo Bonzini.
3260 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3262 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3263 that replaced echo with AS_ECHO where this wasn't necessary.
3264 Problem reportd by Ralf Wildenhues.
3265 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3266 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3267 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3269 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3271 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3273 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3275 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3276 that traditional Awk lacks 3-arg "split". It has it.
3277 Mention that FS must be a single character, and a few other
3278 99-byte limits of traditional Awk.
3279 Mention that if (i in a) doesn't work with traditional Awk.
3281 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3283 * tests/autotest.at (BSx641-newline in command):
3284 (BS-BS-newline in command, BSx640-newline in command):
3285 (Newline-CODE-BS-newline in command):
3286 (Single-quote-BS-newline in command):
3287 (Single-quote-newline-BS-newline in command):
3288 Use printf '%s\n' instead of echo, for portability to hosts
3289 where echo interprets backslashes. This will break on hosts
3290 that lack printf, but for now let's assume all such hosts
3291 are dead (if not, we should get reports of test failures).
3293 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3295 'echo' has some portability problems, when given a first argument
3296 with a leading '-', or when given any argument containing '\'.
3297 Avoid using 'echo' in these cases.
3298 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

3301 * lib/autotest/general.m4 (AT_INIT): Likewise.
3302 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
3303 argument might be unportable.

3322 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3323 * bin/autoconf.as: Redo verbose flag implementation, as the old
3324 scheme wouldn't work with AS_ECHO.
3325 * lib/autotest/general.m4 (AT_INIT): Likewise.
3326 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3327 Don't use ECHO_T, since ECHO_N is now reliable.
3328 * lib/autotest/general.m4 (AT_INIT): Likewise.
3329 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3330 rather than using a here-document to put the script into a file.
3331 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3333 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3334 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3335 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3336 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3337 * lib/autotest/general.m4 (AT_SETUP): Likewise.
3338 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
3339 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3340 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3341 operand, as AS_ECHO requires. Avoid double file name expansion.
3342 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3343 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3344 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3345 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3346 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3347 Double-quote strings that would otherwise contain M4 comments.
3348 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3350 * configure.ac (AC_INIT): Bump to 2.61a.
3353 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3357 * configure.ac (AC_INIT): Bump to 2.61.
3360 * tests/autotest.at (Macro with backslash in a test title):
3361 Comment out for now, as this tests neither fails nor passes
3362 reliably. Problem reported by Ralf Wildenhues.
3364 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3366 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
3367 in previous change, which caused test failures.
3369 2006-11-16 Stepan Kasal <kasal@ucw.cz>
3371 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
3372 code for --enable, --disable, --with, and --without to...
3373 (_AC_INIT_PARSE_ENABLE): ... a new macro.
3374 * doc/autoconf.texi (Package Options):

3436 first argument may also contain dots.
3438 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
3440 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
3441 benefit of platforms like Solaris+GCC where it is common to have a
3442 non-working g++ installation.

3449 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
3452 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3454 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
3455 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
3456 Imported from a similar patch to gnulib by Bruno Haible.
3458 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3460 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

3479 Handle special characters in test case titles correctly.
3480 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
3482 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
3483 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
3484 argument. Extend to check titles printed by ./micro-suite and
3485 ./micro-suite -l and the title in micro-suite.log.
3486 (Backquote in a test title,
3487 Single-quote in a test title,
3488 Double-quote in a test title): Don't expect failure anymore.
3489 (Backslash in a test title): Put a non-whitespace character after the
3490 backslash so that Bourne shells might actually see it as an escape
3492 (Brackets in a test title,
3493 Pound in a test title,
3494 Comma in a test title,
3495 Quoted Macro in a test title,
3496 Macro in a test title,
3497 Macro with single-quote in a test title): New tests.
3498 (Macro with backquote in a test title,
3499 Macro with double-quote in a test title,
3500 Macro with backslash in a test title): New tests expected to fail.
3501 * tests/torture.at (#define header templates): M4-quote this title in
3502 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3503 The visible effect was a stray [] in the testsuite output.
3505 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3507 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3508 `trap ... 0' inside a function, for AIX sh.
3510 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3512 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3513 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3514 5363) simply issues a warning when dividing by zero at compile
3515 time. Problem reported by Elias Pipping.
3517 2006-10-26 Eric Blake <ebb9@byu.net>
3520 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3521 show effect on macros that expand with commas.
3522 Reported by Joel E. Denny.

3544 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
3546 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
3548 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3549 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3550 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3551 reported by Nelson H. F. Beebe for Coreutils 6.4.
3553 * tests/tools.at (autoconf --trace: user macros): Remove test
3554 for tracing multiline macros, since m4 1.4.7a uses a different
3555 way to number lines. Problem reported by Ralf Wildenhues.
3557 2006-10-24 Stepan Kasal <kasal@ucw.cz>
3559 * bin/autom4te.in (handle_m4): Do not redirect stdin to
3560 /dev/null since the heuristics for interactive behaviour was
3563 * bin/autom4te.in: With --force, always refresh the output
3564 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
3566 * bin/autoconf.as: Fix the verbose message at the end.
3568 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

3582 * doc/autoconf.texi (Caching Results): Likewise.
3583 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
3584 AC_CACHE_CHECK_INT, since it's no longer public.
3585 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
3586 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

3617 looking for special shell characters.
3618 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
3619 macro defined by AS_VAR_PUSHDEF before passing it as a

3631 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
3633 (Imported from Automake.)
3634 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3635 which incorrectly sets the mode of an existing destination
3636 directory. In some cases the unpatched install-sh could do the
3637 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3638 system. We hope this is rare in practice, but it's clearly worth
3639 fixing. Problem reported by Alex Unleashed in
3640 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3641 Also, don't bother to check for -m bugs unless we're using -m;
3642 suggested by Stepan Kasal.

3650 is enabled by default with gnu and gnits strictness.
3651 Report from Bruno Haible.
3653 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

3655 gnu and gnits modes.
3657 Import this change from Config:

3662 Import this change from Gnulib:
3664 2006-09-16 Karl Berry <karl@gnu.org>
3665 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
3666 to avoid sectioning errors.
3668 Import these changes from Texinfo:
3670 2006-10-04 Karl Berry <karl@gnu.org>
3671 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
3672 (\quoteexpand): rename to \rquoteexpand.
3673 (\codequoteleft): new def, to look for @set codequotebacktick.

3675 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
3676 (\code): must use new \...Char values, since now ` is active.
3678 2006-08-26 Karl Berry <karl@gnu.org>
3679 * build-aux/texinfo.tex (\textdegree): New command.
3681 2006-08-12 Karl Berry <karl@gnu.org>

3686 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
3688 2006-10-13 Stepan Kasal <kasal@ucw.cz>
3690 * doc/autoconf.texi (Autoheader Macros): Warn that the text
3691 added to the template can get mangled.
3693 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3695 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
3696 include the default headers, and redefine obstack_chunk_alloc
3697 and obstack_chunk_free. Fixes false failure with glibc.
3699 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
3701 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

3713 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
3714 the NonStop platform.
3715 * doc/autoconf.texi (Posix Variants): Likewise.
3716 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
3718 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
3719 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
3720 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
3721 Use a better substitute, by inspecting the output of "ls"
3722 rather than just using ":".
3723 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
3724 rather than AS_EXECUTABLE_P, since we needn't worry about
3725 non-regular files here.
3727 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
3728 due to configuration hassles with this. See Tonya Underwood's report
3729 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

3738 2006-10-11 Stepan Kasal <kasal@ucw.cz>
3740 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
3741 initialization which is not inherited through the environment
3742 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
3743 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
3745 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
3747 * doc/autoconf.texi (Limitations of Usual Tools): Describe
3748 problems with mkdir -p -m.
3750 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
3752 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
3753 comment about ac_cpp_err; it was incorrect, and anyway
3754 ac_cpp_err is being removed below.
3755 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
3756 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
3757 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
3759 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
3760 with werror_flag and conftest.err and so forth. This is more
3761 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
3762 and anyway the user shouldn't normally want to see this gorp logged.
3763 Problem reported by Ralf Wildenhues.
3764 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
3765 empty, not 'no', since the rest of the code uses 'test -z'.
3767 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
3769 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3770 Use a single call to AC_DO_TOKENS rather than multiple, for
3772 (_AC_LINK_IFELSE): Test that resulting file is executable.
3773 Problem reported by mwoehlke in
3774 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
3776 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
3777 than creating a file to use with test -x; this is much faster.
3779 2006-10-02 Bruno Haible <bruno@clisp.org>
3781 * lib/autom4te.in (Automake-preselections): Add
3782 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
3784 2006-09-27 Stepan Kasal <kasal@ucw.cz>
3786 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
3787 standard error, `experr' should be used, not `expout'.
3789 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
3791 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
3792 fseeko testing program twice; just use the earlier result.
3793 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3794 Set cache var to 'unknown' (not 'no') if leaving the macro unset
3795 still doesn't let the program compile.
3796 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
3799 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
3800 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
3801 include it, without including anything else.
3802 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
3804 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
3806 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3808 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
3809 `error.h', and include it, for a `error_at_line' prototype.
3810 Use a nonempty format string in the link test.
3811 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
3812 for a declaration of wait3.

3817 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
3818 can apply to constants too, and that it checks for macro defns.
3819 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
3820 and simply cast the identifier to void. This handles structure
3821 values. Problem reported by Ralf Wildenhues.
3822 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
3824 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3911 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check

3916 7.1.4 /usr/bin/posix/sh described by Tim Rice in

3921 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
3922 works with GNU M4 1.4.3 again; make the normalized form
3923 match the current m4 message; fix the description.

3932 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of

3982 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
3983 except the first two arguments are reversed.
3984 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
3985 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
3986 caches nor outputs a diagnostic. Suggested by Bruno Haible.

4035 didn't work if some values were cached but not others. Test for
4036 broken lex libraries like native ia64-hp-hpux11.22; see
4037 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4038 work around the problem by preferring an empty LEXLIB to -lfl or
4039 -ll. Let the user set LEXLIB='' to indicate no library needed.

4228 less skeptical about "volatile", after discussion with
4229 Bruno Haible on bug-gnulib.

4269 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4270 more globally, since the 2006-06-30 patch didn't suffice. Problem
4271 reported by Keith Marshall. Also, don't bother with builddir2,
4272 since it shouldn't be needed any more.
4274 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

4293 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4295 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4296 Require that long long int be at least 64 bits wide. C99 requires
4297 this and enough programs depend on it so we should check for it.
4298 Bruno Haible reports in
4299 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>

4311 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4313 * doc/autoconf.texi: Be more consistent about using @acronym with
4314 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4315 quite right (it talked about "OSF/Tru64", even though the
4316 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4317 and it even mentioned "OSF 4"!) and at this point there's little
4318 reason to talk about OSF any more, since it died in 1994.
4319 (Specific Compiler Characteristics): Simplify example of
4320 negative-size array.
4321 (File Descriptors): Reorder to make the text flow better.
4322 Remove joke about "appreciate the various levels"; I didn't get it.
4323 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4324 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4325 (File Descriptors, Limitations of Usual Tools):
4326 Tone down the advice against renaming or removing open files.
4327 (Limitations of Usual Tools): Add a new section, on 'rm'.
4329 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4331 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4332 -lXt in LIBS, idea from Karsten Hopp; this was due since
4335 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4336 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4337 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4338 (which belong to Xt, not X itself). See Debian bug 327655.
4340 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4342 * configure.ac (AC_INIT): Bump to 2.60a.

4362 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4364 * doc/autoconf.texi (Changed Directory Variables): New node,
4365 to document the whole `datarootdir' business a bit better.
4367 * tests/torture.at (datarootdir workaround): Extend test.
4368 Prompted by report by Alexandre Julliard.
4370 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4372 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4373 when using default mode of IBM C 6 for AIX. Problem and two-line
4374 fix reported by Larry Jones.
4376 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4378 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4379 about literal '${datarootdir}' if a definition is found in the
4382 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4384 * NEWS: Use "M4" rather than "m4" when appropriate.
4385 Problem reported by Eric Blake.
4386 * doc/autoconf.texi: Likewise.
4387 Use @acronym around BSD, GCC, and GNU when appropriate.
4388 (Why GNU M4): Renamed from "Why GNU m4".
4389 (Redefined M4 Macros): Mention that Posix
4390 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4391 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4394 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4396 * bin/autom4te.in (handle_output): Do not forbid the empty
4398 * tests/tools.at (autoconf: the empty token): New test.
4400 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4402 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4403 calls, so that we do not care whether they are LIFO or FIFO;
4404 in the m4_wrap, do not check which diversion is the topmost
4405 one, just check that the stack is balanced at the end.
4406 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4407 base diversion forever--pop the previous diversion before
4408 opening the new one; consequently, remove the m4_wrap call.
4409 * lib/autotest/general.m4 (AT_INIT): Likewise.
4410 * tests/m4sugar.at: Do not use
4411 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
4413 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4414 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4416 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4417 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4418 Rework example of m4wrap token-pasting trouble so that it doesn't
4419 care whether it's LIFO or FIFO.
4420 Fix some "contrary to"s that are awkward in English.
4422 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4424 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4425 to `yes' instead of `int$1_t' if the type is found, for more
4426 consistent configure output (where $1 is the number of bits).
4427 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4428 Suggested by Bruno Haible.
4430 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4431 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4432 with system headers. Report by Bruno Haible.
4434 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4436 * config/config.guess, config/config.sub: Sync from upstream.
4438 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4439 in order to avoid picking up an older installed frozen m4sh.m4f.
4440 Besides an outdated shell startup, this could have been created
4441 by an earlier M4 version with incompatible frozen file format.
4443 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4445 * README: Recommend m4 1.4.4 instead of 1.4.3..
4446 * doc/autoconf.texi: Likewise.
4447 (Special Chars in Names): Say that $(.FOO) is portable, as
4448 suggested by Stepan Kasal.
4449 (Installation Directory Variables, Build Directories):
4450 (Automatic Remaking, Subdirectories, Fortran Compiler):
4451 (Making testsuite Scripts, Defining Directories):
4452 Quote variable usages better.
4453 (Making testsuite Scripts): Add clean-local rule to makefile
4454 snippet, by Eric Blake.
4455 (Installation Directory Variables): Fix table item font.
4456 Reword slightly to clarify. Generalize advice about
4457 not using special characters to include all file-related
4458 vars, not just VPATH.
4459 (Special Chars in Variables): Warn about special characters in
4461 (Assignments): Clarify default-value example as suggested by
4463 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4464 (Special Shell Variables): Note leading ./ or ../, as suggested
4466 (Limitations of Builtins): Under cd, warn about CDPATH.
4467 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4470 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4472 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4473 `@var', for texi2html.
4474 (Systemology): Some more word wrapping, for DVI output.
4475 (autom4te Invocation): The short option for `--melt' is `-M',
4478 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4480 * doc/autoconf.texi: More formatting and English tweaks,
4481 many suggested by Ralf Wildenhues.
4482 Reword to avoid "@code{...}'s" and the like, since it's ugly
4483 with Emacs info mode. discontents -> woes.
4484 Put a few "will"s back. time stamp -> timestamp.
4485 side-effect -> side effect.
4487 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4489 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4490 Warn about $@ not persisting. Problem reported by Julien Danjou in
4491 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4492 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4493 Mention other special chars, too.
4495 2006-06-14 Eric Blake <ebb9@byu.net>
4497 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4499 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4501 * doc/autoconf.texi: Some systematic minor improvements, as
4502 follows. Use "makefile" when talking about makefiles
4503 generally (which might be named "makefile" or "Makefile" or even
4504 "foo.mk"), "Makefile" when talking about a specific makefile
4505 called "Makefile". This unclutters the text from weird quotes
4506 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4507 values" rather than "@var{foo}s" and similar constructs containing
4508 "}s". Use "Make rules" rather than "Makefile rules". Minor
4509 English-language improvements. Change the prefix "sub-" to "sub"
4511 Put blank lines around examples more consistently.
4512 Avoid "rather" and "very" as intensifiers.
4513 Avoid "will" as an auxiliary.
4514 (Limitations of Make): Split this node into....
4515 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4516 (Leading _ in Macro Names, Backslash-Newline-Newline):
4517 (Backslash-Newline Comments, Long Lines in Makefiles):
4518 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4519 (obj/ and Make, make -k Status, VPATH and Make):
4520 (VPATH and Double-colon, $< in Explicit Rules):
4521 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4522 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4523 New nodes, resulting from splitup of Limitations of Make.
4524 All cross-references changed. Raise the top node from
4525 a section to a chapter, and all subnodes accordingly.
4526 Redo the introductory wording to match the new organization.
4527 (Installation Directory Variables): Use an example that is
4528 closer to what Autoconf actually does. Mention that VPATH's
4529 value should not contain metacharacters or white space.
4530 (Fortran Compiler): Fix a VPATH bug in an example.
4531 (Leading _ in Macro Names): Mention that this problem is no longer
4532 of practical concern.
4533 (VPATH and Make): Reword the advice to make it clearer
4534 that Autoconf and Automake support VPATH in non-GNU make, but
4535 many packages have bugs in this area.
4536 ($< in Explicit Rules): Refer to Build Directories rather
4537 than using a (non-VPATH-safe) example.
4538 (Automatic Rule Rewriting): Mention the sort of disaster that
4539 can ensue with Solaris-style rule rewriting with VPATH.
4541 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4543 * doc/install.texi (Compilers and Options): Weaken the
4544 suggestion to use GNU make for VPATH builds.
4546 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4547 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4549 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4550 in regular expression.
4552 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4554 * doc/autoconf.texi (Installation Directory Variables):
4555 Drop extra @samp from `@table @samp' item.
4556 (Limitations of Usual Tools): Comment fix.
4557 Do not nest @samp just to point to other table items.
4558 (Writing testsuite.at) <AT_CHECK>: The second argument to
4559 `@dvar' is already @samp'ed.
4560 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4561 do not use @var in the second argument.
4563 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4565 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4566 $as_shell.exe too. Problem reported by Andreas Buening in
4567 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4569 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4571 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4572 `unused variable' compiler warning, for `-Wall -Werror'.
4573 Reported by Jaap Haitsma in
4574 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4576 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4578 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4579 case the compiler dumps core. Problem reported for
4580 OpenServer 5.0.7 by Tim Rice in
4581 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
4582 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4585 2006-06-06 Tim Rice <tim@multitalents.net>.
4587 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4588 "ERROR" only shows up in "make check" output if there is an
4591 2006-06-06 Eric Blake <ebb9@byu.net>
4593 * tests/tools.at (automatically allowed tokens): Fix typo.
4595 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4597 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
4599 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
4600 typically overflows on x86 CPUs, even though the C standard
4603 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4605 * configure.ac (AC_INIT): Bump to 2.59e.
4608 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4612 * config/texinfo.tex: Sync from upstream.
4614 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4615 seen, invoke libtoolize with `--ltdl' argument.
4616 * lib/autom4te.in (Autoreconf-preselections): Adjust.
4618 Suggested by Eric Blake.
4620 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4622 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
4623 reported by Ralf Wildenhues.

4630 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4632 * doc/autoconf.texi: Modernize some of the references to Solaris.
4634 2006-06-05 Stepan Kasal <kasal@ucw.cz>
4636 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
4637 message issued by AC_REQUIRE.
4638 * tests/m4sugar.at: Check m4_require's error message.
4639 * tests/base.at: Check AC_REQUIRE's error message.
4640 * tests/local.at (AT_CHECK_M4): New macro, almost identical
4642 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
4644 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
4645 `expout' as the last parameter.
4646 * tests/tools.at: Adapt to the above change.
4648 2006-06-04 Stepan Kasal <kasal@ucw.cz>
4650 * doc/autoconf.texi (Limitations of Usual Tools): Correct
4651 information about race-free implementations of mkdir.
4653 2006-06-04 Eric Blake <ebb9@byu.net>

4658 * doc/autoconf.texi (autom4te Invocation): Likewise.
4660 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
4662 * NEWS: GNU make now recommended for VPATH builds.
4663 Mention that some macros are now documented to be obsolescent.
4664 * doc/autoconf.texi:
4665 Prefer "current" to "modern" to describe
4666 currently-used (albeit perhaps old-fashioned) hosts.
4667 Mention which ancient features no longer need to be worried about.
4668 setgid -> set-group-ID
4669 setuid -> set-user-ID (these are the Posix terms)
4670 Fix some misuses of "only".
4671 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
4672 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
4673 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

4680 Mention that these macros are obsolescent.
4681 (Installation Directory Variables): shall -> should
4682 (File Descriptors): Mention that 0, 1, 2 might get reopened.
4683 Mention that it's now safe to use 3 and 4.
4684 (Limitations of Usual Tools): cp -r is now specified by Posix.
4685 Omit longwinded and obsolescent discussion of cp -f.
4686 Modernize discussion of expr, ls.
4687 (Limitations of Make): Modernize discussion of VPATH builds.
4688 Mention $? as a workaround in some cases.
4689 * doc/install.texi (Basic Installation):
4690 Mention "./configure; make; make install" first. Be more
4691 specific about why this file is generic. Remove unnecessary
4692 parens. Remove misleading "only". Remove obsolete advice
4693 about csh. Don't say "configure" takes awhile; say it
4694 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
4695 and CC=c99 rather than CC=c89, as these are blessed by current
4696 Posix. Recommend GNU make if doing a VPATH build.
4698 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
4700 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
4701 examples involving shell prompts.
4703 2006-06-02 Stepan Kasal <kasal@ucw.cz>
4704 and Paul Eggert <eggert@cs.ucla.edu>
4706 * doc/autoconf.texi (Here-Documents): Add details about the
4707 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
4708 use "here-documents" instead of "here documents".
4710 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4716 * doc/autoconf.texi (File System Conventions): Warn about ":"
4717 anywhere in directory names.
4719 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
4721 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
4722 about quoting the case statement, just in case.
4723 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
4724 was fixed in ksh93g; reported by Ralf Wildenhues.
4726 2006-05-31 Stepan Kasal <kasal@ucw.cz>
4728 * doc/autoconf.texi (System Services): Do not document
4729 overriding EXEEXT via ac_cv_exeext=ext.
4730 (Particular Programs) <AC_PROG_MKDIR_P>:
4731 Document that ${MKDIR_P} understands --.

4738 argument with leading hyphen. Problem reported by Paul Eggert.
4740 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4742 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
4743 about quoting ac_try: quote all of it, if any of it seems suspicious.
4744 This means we don't have to worry about ${ or sed any more.
4745 Also, double-quote the case statement, to work around misuses via
4746 underquoting as reported by Ralf Wildenhues in
4747 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
4748 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
4749 undocumented and dangerous macro.

4761 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
4762 since evidently some packages rely on the old, broken behavior.
4763 Problem reported by Ralf Wildenhues in
4764 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
4765 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
4766 pre-2006-05-26 definitions, but leave in the comments that
4767 these macros are dangerous and should not be used.
4768 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
4769 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
4770 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
4771 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
4772 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
4774 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4776 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
4777 the use of 'tr', since this is our only use of 'tr'.
4779 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4780 and Paul Eggert <eggert@cs.ucla.edu>
4782 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
4783 Don't assume 'grep' works on long lines, since AIX grep doesn't.
4785 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4787 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
4788 the output file in the `${datarootdir}' test.
4790 2005-05-28 Stepan Kasal <kasal@ucw.cz>
4791 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4793 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
4794 mention of `datarootdir' in the input file(s), but literal
4795 `${datarootdir}' in the output file, and we haven't warned yet,
4796 then warn as well: the user may have (erroneously) used
4797 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
4798 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
4799 * tests/torture.at (datarootdir workaround): Extend this test.
4802 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4803 and Paul Eggert <eggert@cs.ucla.edu>
4805 * doc/autoconf.texi (autoheader Invocation): The first argument to
4806 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
4807 alternatives and clear up the language a bit.
4809 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
4811 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
4812 ac_config_guess, ac_config_sub, ac_configure.
4813 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4814 Fix typo that prevented an unnecessary space from being removed.
4815 Problems reported by Ralf Wildenhues in:
4816 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
4818 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4820 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
4821 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
4822 Don't use the term "thread-safe" to talk about mkdir race
4823 conditions, since the problem is more a process than a thread
4824 issue. Problem reported by Stepan Kasal in:
4825 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
4826 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
4827 the test for 'install' more closely. Look at MKDIR_P first.
4828 Look in the PATH, and at /opt/sfw/bin.
4829 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
4830 Don't bother to try mkdir -p, since we already check mkdir --version;
4831 just look at the version number. (There's no easy way to check
4832 for race-free implementations.)
4833 * tests/tools.at (autoconf: subdirectories): Adjust to above
4834 changes, since MKDIR_P now might end in "/mkdir -p".
4836 * doc/autoconf.texi (autoheader Invocation): Mention that the
4837 first arg of AC_DEFINE_UNQUOTED must be a literal.
4838 Problem reported by Ben Pfaff in
4839 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
4841 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
4842 * doc/autoconf.texi (Special Chars in Variables): New section.
4843 (Preset Output Variables): Warn about special chars in CPPFLAGS.
4844 (Installation Directory Variables): Quote $(datadir) better.
4845 (Limitations of Builtins): Describe some of eval's trickiness.
4847 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
4848 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
4849 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
4850 in front of every arg, not just trailing args. Quote apostrophes.
4851 (_AC_EVAL_ECHO): New macro.
4852 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
4853 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
4855 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
4856 exposed by quoting of eval argument. Put the command on line line
4858 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
4859 (_AC_PATH_X, AC_PATH_X): Quote more safely.
4860 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
4861 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
4862 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
4863 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
4864 Use eval more safely.
4865 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
4866 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
4868 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
4869 lines, exposed by quoting of eval argument.
4871 2006-05-26 Stepan Kasal <kasal@ucw.cz>
4872 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4874 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
4875 initialization of `ac_cv_exeext', do not override it if it was
4876 already set, unless it was set to `no', for compatibility with
4877 Autoconf-2.13, and comment this.
4878 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
4879 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
4880 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
4881 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
4882 Document that this test may be overridden by setting
4885 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4887 Revert these two patches:
4889 2006-04-06 Eric Blake <ebb9@byu.net>
4890 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4891 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4894 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4895 Clean up _AC_COMPILER_EXEEXT* macros.
4896 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4897 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4898 ac_file to the name of the default output file and call
4899 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4900 initial `rm' of the candidate files...
4901 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4902 the same list in subsequent `rm' calls, and for the temporary
4903 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4904 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4905 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4906 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4907 no longer needed) by libtool. Make it a cache check.
4908 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4909 copied here by mistake.
4910 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4911 _AC_COMPILER_EXEEXT.
4912 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
4913 _AC_COMPILER_OBJEXT directly.
4914 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4916 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4918 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
4919 Fix description of how the buggy `sed' works.
4921 2006-05-25 Noah Misch <noah@cs.caltech.edu>
4925 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
4926 ENOLCK. Only mention `make -j' when applicable. Only raise
4927 fatal errors when `make -j' is involved. Improve error message.
4929 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4931 * doc/autoconf.texi (Here-Documents): We now know more about
4932 the variable expansion in here documents bug.
4933 Thanks to Tim Rice and Stepan Kasal.
4935 * doc/autoconf.texi (Making testsuite Scripts): Add an example
4936 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
4938 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4940 * tests/autotest.at (Multiline command from M4 expansion):
4941 No failure to be expected if the shell quotes newlines in
4942 commands in the `set -x' output. Report by Tim Rice.
4945 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4947 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
4948 expansion in the here-documents used by config.status, as that
4949 runs afoul of the Korn shell version M-12/28/93d bug described in
4950 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
4951 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
4952 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
4954 2006-05-23 Jim Meyering <jim@meyering.net>
4956 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
4957 Fix typo introduced with 2006-04-02 change. It reversed the sense
4960 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4962 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
4963 ac_dB slightly, to save bytes in the script.
4964 Max out at 50 lines, rather than 96; this is more likely
4965 (though not guaranteed) to avoid obscure 'sed' failures.
4967 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4969 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
4970 `tr -d -' as bad option argument. Work around this by deleting
4971 an unrelated character.
4972 Report by Tim Rice <tim@multitalents.net>.
4974 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
4975 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4976 Stepan Kasal <kasal@ucw.cz>
4978 * doc/autoconf.texi (Particular Programs): Do not promise that
4979 we always prefer the GNU version of the program, and that we
4980 search according to PATH; both rules can have exceptions.
4981 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
4982 AC_PROG_SED. Move descriptions of limitations
4983 to the Limitations of Usual Tools section.
4984 (Limitations of Usual Tools) <sed>: Mention script length
4985 limitations with Solaris /usr/ucb/sed.
4986 <grep>: Fix wording for empty alternative. Mention that -c and
4987 -l should not be combined, and that -E and -F should not be
4990 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4991 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4993 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
4994 limits in Solaris 8 /usr/ucb/sed by testing a long script.
4996 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4998 * doc/autoconf.texi (Defining Symbols): Literal parameter of
4999 AC_DEFINE is now passed to m4_pattern_allow.
5000 * NEWS: Mention that; likewise for AC_SUBST.
5001 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5002 the parameter to m4_pattern_allow.
5003 * tests/tools.at: Add a check for that.
5005 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5007 * lib/autoconf/status.m4: Fix typos.
5009 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5011 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5012 only the files that this macro generates.
5014 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5016 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5017 the HP-UX sed limitation of 99 commands, labels do not count.
5018 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5020 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5022 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5024 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5025 Import the following fix from coreutils:
5027 2006-01-13 Jim Meyering <jim@meyering.net>
5029 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5030 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5031 not double-quote uses of that variable, to accommodate the rare
5032 case in which getmntent is available in none of the libraries
5033 checked. This happens at least on FreeBSD 5.0.
5035 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5037 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5038 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5039 some other programs unwisely rely on these undocumented vars.
5040 But put in warning comments about them.
5041 Problem reported by Ralf Wildenhues in
5042 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5043 * NEWS: Document that these variables are intended to go away.
5045 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5047 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5048 and set the language to C++ (analogous to the equivalent Fortran
5051 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5052 * doc/autoconf.texi (C++ Compiler): Document it.
5053 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5056 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5058 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5059 that caused config.status to generate 100-command sed scripts; the
5060 portable limit is 99.
5062 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5064 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5065 variable `ac_d' instead of `d' to avoid infringing namespace.
5066 Report by Ralf Menzel.
5068 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5070 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5071 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5072 * tests/tools.at (autoconf: subdirectories): New test, taken from
5073 the corresponding problem report by Ralf Wildenhues in:
5074 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5076 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5077 Quote some uses of shell variables if they might suffer unexpected
5078 globbing. This doesn't fix all instances of quoting problems that
5079 I found, just the easy ones that look safe.
5080 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5081 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5082 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5083 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5084 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5085 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5086 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5088 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5089 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5091 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5093 * bin/autoreconf.in ($help): Reword according to the manual.
5094 Suggested by Olly Betts.
5096 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5097 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5099 * bin/autoreconf.in: Pass the directory argument to
5100 `require_configure_ac'. Fix comment.
5101 * tests/torture.at (Configuring subdirectories): Expose this.
5102 Reported by Olly Betts.
5104 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5106 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5107 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5108 Automake as follows:
5110 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5111 `$configure_in' instead of `configure.in', to preserve
5112 directory component.
5114 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5116 * config/config.guess, config/config.sub, config/texinfo.tex,
5117 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5119 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5121 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5122 test for C99 conformance; (bool) 0.5 is an integer constant
5123 expression, but (bool) -0.5 is not. Problem reported by Fedor
5124 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5126 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5128 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5129 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5130 Warn about obsolete install-sh files. Remove stray sentence
5131 fragment and fix cross reference.
5132 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5133 install -d; this undoes the 2006-05-10 change.
5134 (MKDIR_P): Mark with AN_MAKEVAR.
5135 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5136 that we don't require $INSTALL to be thread-safe. Move comments
5137 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5138 of AC_PROG_INSTALL. Output a message saying that we're checking
5139 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5140 MKDIR_P instead of AC_SUBST.
5141 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5142 Special magic for MKDIR_P, too.
5143 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5145 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5147 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5149 Sync from Automake, as follows:
5151 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5152 * config/install-sh: Initialize IFS, so field splitting isn't
5154 * config/mkinstalldirs: Likewise.
5155 * config/missing: Remove superfluous quotes. Replace all uses of
5156 `[' by `test', for consistency, and for..
5157 * config/missing (sed_minuso, sed_output): New variables.
5158 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5159 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5160 Fixes `missing' to detect `--output' for help2man. Fixes
5161 PR automake/483. Report by Dennis J. Linse.
5162 (autom4te): Document in `missing --help'.
5164 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5166 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5167 * config/install-sh: Don't use 'path' to talk about file names,
5168 as per GNU coding standards. Close a race condition reported by Ralf
5169 Wildenhues and Stepan Kasal. There is still a race condition
5170 on hosts that predate Posix 1003.1-1992, but we can't help this.
5171 Don't mishandle weird characters like space on pre-Posix hosts.
5172 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5173 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5174 AC_PROG_MKDIR_P from AS_MKDIR_P.
5175 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5176 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5177 earlier editions are not (including Automake 1.8.3).
5178 Do not suggest mkinstalldirs for thread-safety.
5179 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5180 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5181 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5182 presence of special characters and race conditions.
5183 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5184 in Autoconf's name space.
5186 2006-05-10 Bruno Haible <bruno@clisp.org>
5187 and Paul Eggert <eggert@cs.ucla.edu>
5189 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5190 from Automake with minor changes.
5191 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5193 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5195 * config/install-sh: Update to Automake CVS version, as follows:
5196 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5197 * lib/install-sh: Simplify the expr implementation of dirname.
5198 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5199 * lib/install-sh: Handle --, and diagnose unknown options.
5201 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5203 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5204 `./autom4te' to create `./testsuite', since the `all' target
5205 will ensure its presence, but `installcheck' should not create
5206 the uninstalled wrappers.
5208 * tests/torture.at (Unusual Automake input files): Skip if we
5209 detect automake < 1.8.
5211 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5213 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5214 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5215 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5218 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5220 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5221 munge (multiple) white space and other oddities.
5222 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5223 single quotes in variable assignment.
5224 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5225 and similar failures by adding multiple spaces, tabs, and other
5227 Report and different test suggested by Francesco Romani
5228 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5230 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5231 single quotes, we only need to search for single quotes; this
5232 both simplifies the search pattern, and makes us less
5233 susceptible to `echo' variations for arguments not containing
5235 (_AC_ARG_VAR_VALIDATE): Likewise.
5237 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5239 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5240 `$*' and IFS concatenation issue with traditional shells and
5241 bash-2.04. Report by Seanster@Seanster.com.
5243 2006-05-03 Bruno Haible <bruno@clisp.org>
5245 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5246 precisely which Mac OS X versions have the od problem.
5248 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5250 * doc/autoconf.texi: Use @option systematically.
5252 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5253 and Bruno Haible <bruno@clisp.org>
5255 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5257 (Integer Overflow): Mention the special case of integer division
5260 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5262 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5263 traditional shells like the Solaris one that do not use the
5264 first IFS character for assembling `$*'.
5265 Prompted by a related report from autoconf_bug@nro.ca.
5267 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5268 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5270 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5271 Mention more problems with the -e option.
5273 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5276 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5278 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5279 in URLs to improve DVI formatted output (requires texinfo 4.6).
5280 (System Services, Systemology, Shellology): Likewise.
5281 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5284 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5286 (Runtime): Fix macro argument names to match description:
5287 `action-if-found' -> `action-if-true' and similarly.
5288 (Obsolete Macros): Likewise.
5289 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5290 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5291 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5293 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5295 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5298 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5301 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5303 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
5304 /bin/sh set unsorted output.
5305 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.

5310 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
5311 (Integer Overflow, Null Pointers, Buffer Overruns):
5312 (Floating Point Portability, Exiting Portably): New sections.
5313 (Writing Test Programs): Fix some langauge. Recommend exiting
5314 with status 1, not merely nonzero. Clarify exit declaration.
5315 (Run Time): Move C exit status stuff to new Exiting Portably section.
5316 (Systemology): Mention Posix and levenez. Update v7 reference.
5317 (Portable Shell): Mention the Posix shell.
5319 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5321 * bin/autoconf.as (me): Replace by as_me.
5323 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5325 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5326 since as_me isn't set yet.
5328 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5330 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5331 a few minor bugs in this area.
5333 * doc/autoconf.texi (Programming in M4sh): Comment out the
5334 documentation of AS_BASENAME, for now.
5335 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5336 (Limitations of Builtins) <basename>: Do not refer to
5338 * bin/autoconf.as (me): Don't use AS_BASENAME.
5339 (dir): Remove the unused variable.
5340 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5341 AS_DETECT_REQUIRED. All uses changed.
5342 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
5344 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
5345 (AS_BASENAME): Use "basename --" to protect against leading "-".

5347 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
5348 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
5349 (_AS_DIRNAME_PREPARE): Likewise.
5350 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
5351 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5352 (AS_DIRNAME): Use "dirname --".
5354 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5356 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5357 of "run time" and "run-time" changed to "runtime", for consistency.
5358 * lib/autoconf/fortran.m4: Likewise (in comment).
5359 * lib/autoconf/functions.m4: Likewise.
5360 * lib/autoconf/general.m4: Likewise.
5361 * lib/autoconf/headers.m4: Likewise.
5363 * doc/autoconf.texi (Run Time): Document the exit status situation
5364 with more accuracy and detail.
5366 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5368 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5369 Archive is not officially `GNU' any more. Update URL.
5370 (Defining Directories): Likewise
5371 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5373 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5375 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5376 newline from the `trap' code to finish `config.log'; the NetBSD
5377 /bin/sh resets the exit status after an empty command, as
5378 documented in doc/autoconf.texi.
5379 Reported by Dalibor Topic <robilad@kaffe.org>.
5381 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5383 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5384 Suggested by Bruno Haible.
5386 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5388 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5389 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5390 Instead, just list the shells that we know work.
5391 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5392 changed. Be more cautious about the _cv_ variable.
5393 * tests/tools.at (Syntax of the shell scripts): Check the
5394 _cv_ variable once, at first, to avoid an internal autoconf error
5395 when sh -n does not work.
5397 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5399 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5401 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5403 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5404 use ">&-" since we're only 99.999% sure that this is portable,
5405 and since the MinGW bug is fixed in a different way.
5406 * lib/autotest/general.m4 (AT_INIT): Likewise.
5408 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5410 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5411 before opening config.log, to avoid hitting a bug on MinGW.
5413 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5415 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5416 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5417 This works around a MinGW bug reported by Eric Paire.
5418 Make sure that all writes to the log file append to it,
5419 rather than possibly losing data.
5420 * lib/autotest/general.m4 (AT_INIT): Likewise.
5422 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5424 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5427 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5431 * configure.ac (AC_INIT): Bump to 2.59d.
5433 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5437 * Makefile.maint (news-date-check): Do not require a leading `*'
5438 before the release date in NEWS.
5440 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5441 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5443 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5444 the instantiated file do not contain the string 'datarootdir'
5445 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5446 @mandir@, replace the reference '${datarootdir}' by the value.
5447 * tests/torture.at (datarootdir workaround): New test.
5448 * NEWS: Advertise this temporary fixup.
5449 Based on a patch by Bruno Haible, reported and analyzed by
5450 Paul Eggert and Noah Misch.
5452 2006-04-12 Eric Blake <ebb9@byu.net>
5454 * tests/autotest.at (Debugging a failed test): Fix comment.
5456 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5458 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5459 all the changes since 2006-04-07.
5461 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5463 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5464 succeeded, but `ln -s file dir' failed, take care to remove the
5465 leftover target before the next test, to prevent its spurious
5466 failure; also make sure `ln file dir' works before selecting it.
5467 Thanks to Keith Marshall for pointing this out.
5470 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5471 assignments in `at_debug_args', so that we put them correctly
5472 in the `run' script.
5473 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5474 Reported by Eric Blake.
5476 2006-04-11 Eric Blake <ebb9@byu.net>
5478 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5479 top-level tests after micro-suite has been run. Used in...
5480 (Debugging a successful test, Debugging script and environment),
5481 (Debugging a failed test): ...these new tests. The first of these
5483 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5484 macro, split out from...
5485 (AT_INIT): ...here, so that using -d also generates a run script.
5486 Document that -d inhibits top-level logging.
5487 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5488 inhibits top-level logging; debug scripts are created.
5490 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5492 * tests/autotest.at (Empty test, Empty check): New test to check it.
5494 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5497 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5499 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5500 the files if a problem appears. Make the empty *.at files
5501 read-only, too. Proposed by Ralf Wildenhues.
5503 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5505 * config/Makefile.am: Add comment to force updated Makefile.in.
5507 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5508 space only patch to this file, this patch causes the Makefile.in
5509 files that include freeze.mk to be updated, and thus have a
5510 newer time stamp again, which in turn makes a pristine CVS
5511 checkout have correct time stamps.
5513 * Makefile.maint (cvs-sv): New macro, to be used..
5514 (config.guess-url_prefix, config.sub-url_prefix)
5515 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5516 point to CVS text checkout of Gnulib files.
5517 (copyright-check): Bump current year.
5518 (announcement): Do not hard-wire `./announce-gen'.
5519 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5521 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5523 (wget_files): Update config.guess, config.sub, texinfo.tex by
5524 `wget-update', now that their URLs work again.
5526 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5528 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5529 Problem noted by Paul D. Smith.
5531 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5533 * doc/autoconf.texi: Remove unused words from word list.
5534 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5535 .x-sc_trailing_space: New files.
5537 * doc/standards.texi: Sync from gnulib.
5539 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5540 `LIBOBJDIR' as experimental.
5542 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5543 with a target directory; it's internally implemented as `cp'
5544 anyway, but since Autoconf advertises the possibility to use
5545 a target directory when LN_S is `ln -s', we need to find out.
5546 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5547 analyzed by Keith Marshall <keith.marshall@total.com>.
5551 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5553 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5554 confdefs.h as-is. In general, if it has backslash-newline or the
5555 like, then it doesn't work either to sort or to remove empty
5558 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5560 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5562 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5564 * lib/autom4te.in (Automake-preselections): Preselect
5567 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5569 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5570 apostrophe within a single-quoted string, as this is the usual
5571 tradition and is easier to read than '"'"'. Don't rely on the
5572 shell treating "$/" like '$/'. Use a more-consistent indenting
5575 2006-04-09 Eric Blake <ebb9@byu.net>
5577 * tests/autotest.at (Backquote command substitution),
5578 (Multiline backquote command substitution): Remove mistaken
5579 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5581 (Parenthetical command substitution, Multiline parenthetical
5582 command substitution): here.
5584 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5586 Import macros from gnulib (often changing their name).

5615 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
5616 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
5617 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
5618 (C Compiler): Move AC_C_LONG_DOUBLE to ...
5619 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
5620 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
5621 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
5622 (Coding Style). Don't mention m4_expand_once.
5623 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

5643 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
5644 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
5646 2006-04-08 Stepan Kasal <kasal@ucw.cz>
5648 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
5649 of the warning introduced by the 2001-08-28 change.
5651 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
5652 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5654 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
5655 variables shall be overriden by the cache.

5659 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5661 Revert the patch from 2006-04-01 and only improve
5662 _AS_DETECT_BETTER_SHELL:
5664 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
5665 skip nonexistent directories.
5666 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
5667 only shell candidates which exist.
5668 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
5669 * lib/autotest/general.m4 (AT_INIT): No need to give three
5670 parameters to _AS_PATH_WALK.
5672 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
5673 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5675 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
5676 distinguish m4sugar macros.
5677 * tests/tools.at (autoupdating with aclocal and m4_include):
5678 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
5679 test case by Noah Misch <noah@cs.caltech.edu>.
5681 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5683 Revert my change from 2006-03-17, in other words:

5692 * doc/autoconf.texi (Programming in M4sh): Document that
5693 AS_MKDIR_P exits the script on failure.
5694 * lib/autotest/general.m4: Remove redundant AS_ERROR.
5696 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5698 * config/elisp-comp, config/install-sh, config/mdate-sh,

5714 Paul Eggert <eggert@cs.ucla.edu>,
5715 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5717 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
5718 whether `set' quotes correctly: redirect stderr of the tested
5719 `set', and use a subshell, for Ultrix; use `sed' instead of
5720 `grep' for zsh `set' which may write binary output; match only
5721 at the beginning of a line, to avoid false positives.
5722 In order to avoid false positives by unrelated variables with
5723 multiline content, put the dump algorithm in a subshell and
5724 unset all variables containing newlines (except some which are
5725 special to the shell). Warn about cache variables that are
5728 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5730 * config/config.guess, config/config.sub, config/texinfo.tex:
5733 * tests/mktests.sh: Reword comments.
5735 * tests/mktests.sh: Only skip internal macros starting with

5739 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
5740 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
5741 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
5742 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
5744 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
5745 shell issue with double-quoted command substitutions of native
5747 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
5750 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

6715 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
6716 AC_LANG_PROGRAM, fixing a typo. Don't give details about
6717 the inner workings of AC_LANG_FUNC_LINK_TRY.
6718 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
6719 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
6720 by the function rather than ignoring it.
6721 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
6722 comparing its address. Intel's interprocedural optimization was
6723 outsmarting the old heuristic. Problem reported by
6726 2005-10-19 Stepan Kasal <kasal@ucw.cz>
6728 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
6730 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
6732 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
6733 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
6735 2005-10-04 Stepan Kasal <kasal@ucw.cz>
6737 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
6738 before removing it (chmod -R u+rwx); there are three instances of this.
6740 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6741 Stepan Kasal <kasal@ucw.cz>
6743 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
6744 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
6745 make its content writable before removing it. Remove an errorneous
6746 comment from the end, where the logs of the failed tests are copied
6747 to the main log file.
6749 2005-09-27 Stepan Kasal <kasal@ucw.cz>
6751 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
6752 in case the computer is too quick. Double quote the configure.ac
6755 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
6756 problems if the testsuite were running too fast.
6758 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
6760 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
6761 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
6762 (which belong to Xt, not X itself). See Debian bug 327655.
6763 * NEWS: Mention this.
6765 2005-09-07 Stepan Kasal <kasal@ucw.cz>
6767 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
6769 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
6771 * config/move-if-change: Don't output "$2 is unchanged";
6772 suggested by Ben Elliston. Handle weird characters correctly.
6774 2005-09-06 Stepan Kasal <kasal@ucw.cz>
6776 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
6777 calls, so that the final expansion of this macro is shorter.
6778 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
6779 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
6780 the cleanup there. Use AS_VAR_* macros, to be more general.
6781 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
6783 * lib/autoconf/general.m4: Use AS_IF where appropriate.
6785 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
6787 2005-09-01 Stepan Kasal <kasal@ucw.cz>
6789 * doc/autoconf.texi (Configuration Headers): Add an index entry
6792 2005-08-26 Pavel Roskin <proski@gnu.org>
6794 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
6795 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
6798 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
6800 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
6801 The previous patch didn't work, so try a better one.
6803 2005-08-26 Stepan Kasal <kasal@ucw.cz>
6805 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
6806 in the example. Reported by Bruno Haible.
6807 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
6808 "if $undefined_var;" succeeds with my shell.
6810 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
6811 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
6812 but change the m4_divert_text to m4_divert_once.
6814 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
6816 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
6817 Work around bug in Solaris /usr/xpg4/bin/awk.
6818 The bug is present in at least Solaris 8 through 10.
6820 2005-08-24 Stepan Kasal <kasal@ucw.cz>
6822 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
6823 some evil values and relying on the fact that $* concatenates the
6824 parameters by the first character from IFS.
6826 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6827 Stepan Kasal <kasal@ucw.cz>
6829 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
6830 first header appears, define AH_HEADER.
6831 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
6832 Update limitations about when to call AC_CONFIG_HEADERS.
6833 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
6834 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
6835 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
6836 ``Configuration Actions''; fix their index entries.
6838 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
6839 options correctly. Process N-M as M-N if M is smaller than N.
6840 Process ranges correctly so that N-N will run only N.
6841 Sort and uniquify the tests that will be run. If there is more
6842 than one test, reinsert the banners for the tests.
6843 * tests/autotest.at (Keywords): Unmark XFAIL.
6845 2005-08-23 Stepan Kasal <kasal@ucw.cz>
6847 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
6848 before passing the macro name to AH_TEMPLATE.
6850 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
6851 now opens log after option processing; in particular, --version
6852 and --help do not touch config.log.
6854 * Makefile.maint: Revert the change from 2005-08-12.
6856 2005-08-22 Stepan Kasal <kasal@ucw.cz>

6864 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
6865 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
6868 * doc/autoconf.texi (Defining Symbols, Changed Results):
6869 Prepend to LIBS, not append, in examples.
6871 2005-08-16 Stepan Kasal <kasal@ucw.cz>
6873 When building in place, set srcdir="."; suggested by Tim Van Holder.
6875 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
6876 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
6877 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
6878 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
6879 does not mean "no --srcdir option".
6881 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6883 * tests/autoscan.at (autoscan): New file.
6884 * tests/suite.at: Use it.

6886 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
6888 * tests/autotest.at (Keywords): Test keywords combinations.
6890 2005-08-12 Stepan Kasal <kasal@ucw.cz>
6892 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
6893 add "2>&1"; gzip 1.2.4 prints help on stderr.
6895 2005-07-27 Stepan Kasal <kasal@ucw.cz>
6897 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
6898 was pushdef'ed twice while popped only once. Push it only once.
6899 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
6901 2005-07-26 Stepan Kasal <kasal@ucw.cz>
6903 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
6904 prefixed by mere "===", not "configure: === ".
6906 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
6908 * Makefile.maint: Update from Bison.
6910 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
6911 "<tab>" in comment, so that the point is understandable.
6913 2005-07-25 Stepan Kasal <kasal@ucw.cz>
6915 Rewrite substantial part of lib/autoconf/status.m4.
6916 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
6917 and CONFIG_COMMANDS are not processed in four separate loops.
6918 Instead, there is one main loop. This alows that the common code
6919 is expanded only once, thus config.status (and configure) is smaller.
6921 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
6922 the AC_LIST_FILES and cousins macros are no longer used.
6924 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
6925 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
6926 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
6927 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
6928 contain the initialization, nor the for loop, nor the associated
6929 commands; all these go to ...
6930 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
6931 _AC_OUTPUT_CONFIG_STATUS.
6932 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
6933 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
6934 (_AC_OUTPUT_FILE): The creation of the sed script ...
6935 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
6936 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
6937 _AC_OUTPUT_MAIN_LOOP.
6938 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
6939 _AC_CONFIG_COMMANDS): Use ...
6940 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
6941 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
6942 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
6943 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
6944 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
6945 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
6947 (_AC_CONFIG_UNIQUE): Update.
6948 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
6949 Replaced by this ...
6950 (_AC_LIST_TAGS): ... new common macro.
6951 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
6952 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
6953 (_AC_LIST_TAG_COMMANDS): ... new common macro.
6954 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
6955 this didn't belong to the `config commands' section.
6956 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
6957 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
6958 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
6959 to the `config commands' section either.
6960 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
6961 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
6963 ... and many changes to the comments nearby.
6965 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
6966 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
6967 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6968 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
6969 (#define header templates): The comment at the top of the generated
6970 header now includes the name(s) of the source file(s).
6972 Several unrelated small changes:
6974 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
6975 parameter to AC_DIAGNOSE.
6976 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
6977 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
6978 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
6979 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
6981 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
6982 in AC_OUTPUT doesn't double-quote it either.
6983 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
6986 2005-07-10 Stepan Kasal <kasal@ucw.cz>
6988 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
6989 versions of Portland Group compiler produce single- and double-quoted
6990 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
6991 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
6993 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
6995 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
6996 This is a corrected version of yesterday's patch.
6998 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7000 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
7001 path, too; insert a "===" to emphasize the line.
7003 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
7004 ac_cv_build_alias to ac_build_alias.
7005 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7007 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7008 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7009 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7010 (AC_ARG_VAR): ... here.
7011 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7014 Keep a list of all precious variables and process them with one simple
7015 for loop, instead of expanding all commands, or, OTOH, complicated
7016 processing of output of "set".
7017 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
7018 variable names in new macro...
7019 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
7020 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
7021 a loop to assign all ac_env_* and ac_cv_env_* variables.
7022 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7024 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7025 its value to shell variable ac_precious_vars and call
7026 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
7027 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
7028 _AC_ARG_VAR_VALIDATE.
7030 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
7031 and the AC_SUBSTs ...

7035 the ac_subst_files section in config.log.

7053 Fix my changes from 2005-07-01; reported by Noah Misch.
7054 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
7055 description, the macro now accepts only a single tag.

7058 Fix cases when the varsions of Autoconf and Autotest don't match.
7059 Reported by Noah Misch.
7060 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
7061 at_top_builddir, for compatibility with older autotest.
7062 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
7063 is not set, use at_top_builddir, for compatibility with older
7064 versions of autoconf.
7066 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7068 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
7069 Problem reported by Patrick Welche.
7071 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
7073 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7074 sed substitution command, so that we allow | in program prefixes
7075 and program suffixes. (& is a problem anyway; we're not fixing
7077 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
7078 configure_input, top_builddir, srcdir, etc.
7079 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7080 PATH_SEPARATOR in AUTOTEST_PATH.
7082 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
7084 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
7085 for loop over config.site files using `set', to allow
7086 directory names containing IFS characters.
7088 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
7090 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
7091 directories with weird names. Apparently some people like living
7092 on the edge. However, improve the test that "pwd" actually does
7093 report a name for the working directory.
7094 * NEWS: Remove the claim that we test for funny chars in dir names.
7096 2005-07-01 Stepan Kasal <kasal@ucw.cz>

7112 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
7113 document to output the default config_* lists to config.status.
7114 Don't recognize option --file, if the functionality is not there.
7115 Likewise for --header; moreover, recognize --he and --h as shortcuts
7116 for --help in that case.
7118 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7119 matches the order of execution. No code changed.

7140 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
7141 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7142 (AC_SUBST): Call it.
7143 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7144 the directory specific variables; but don't call it for configure_input.
7146 2005-06-28 Derek Price <derek@ximbiot.com>
7148 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7151 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7153 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
7154 directory have inherent problems with special characters like spaces,
7155 due to limitations in Make syntax. Problem reported by Alexandre
7157 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
7158 Also, fix Tru64 porting problem with shell patterns,
7159 reported by Ralf Wildenhues.

7167 * tests/local.at (AT_CHECK_ENV): Simplify regexp slightly.
7169 Fix some more shell quoting problems. Prompted by a bug report
7170 from Justace Clutter.
7171 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7172 variable into diagnostic. Make the diagnostic an error, not a warning,
7173 because we really don't support spaces and suchlike in dir names.
7174 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7175 Don't worry about backslashes in srcdir; it can't happen now.

7186 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
7188 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
7189 that '\|' is not allowed in BREs; recommend using newline separated

7200 2005-06-21 Stepan Kasal <kasal@ucw.cz>
7202 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
7203 b, t, r, w commands require single space, while : cannot have any.
7204 (Special Shell Variables): Fix sed code this in the example.
7205 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7206 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
7208 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

7214 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
7216 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
7218 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
7219 * doc/autoconf.texi:
7220 Don't mention Solaris versions so much, if a
7221 problem is common to all extant versions of Solaris. Say "SunOS
7222 4" instead of "SunOS" for SunOS 4.
7223 (awk): Mention more of the limitations of traditional Awk.

7240 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
7242 * doc/autoconf.texi: "filesystem" -> "file system".
7243 "behaviour" -> "behavior".
7244 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
7245 * lib/autoconf/general.m4: Omit blank after ":" sed command,
7247 * lib/m4sugar/m4sh.m4: Likewise.

7249 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
7251 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.

7266 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7267 -u, since it outputs chatter if the input files are the same.
7268 Problem reported by Ralf Menzel.
7270 2005-06-08 Derek Price <derek@ximbiot.com>
7272 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7273 renaming them since they are about to be redefined anyhow.
7275 2005-06-08 Derek Price <derek@ximbiot.com>
7277 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7278 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7279 Move m4_undefine to alphabetical order.
7281 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
7283 * README: Recommend GNU M4 1.4.3 or later.
7284 * doc/autoconf.texi (Introduction): Likewise.
7285 Reword to avoid some formatting glitches.
7286 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7287 Clarify explanation of HP compiler bug.
7288 Redo example output tp match current CVS snapshot.
7289 Use @example.org in email addresses when the examples
7290 might get inadvertently cut-and-pasted into user code.
7291 Remove example of autom4te usage that doesn't seem to work now.
7292 Use modern AC_INIT (except when the example is meant to be
7293 shown with Autoconf 2.13).
7294 Update ksh info for Solaris 9 and later.
7296 Modernize description of Automake versions a bit.
7297 Don't claim a future version of Autoconf is near.
7298 * doc/install.texi: Reword to avoid some formatting glitches.
7300 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7303 follows its own advice about quoting better.
7304 Reword to avoid some formatting glitches.
7305 * doc/installt.exi: Reword to avoid some formatting glitches.
7307 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7308 Tru64 ksh pattern matching bug. Reported against Libtool by
7309 Albert Chin <libtool@mlists.thewrittenword.com> and
7310 Nicolas Joly <njoly@pasteur.fr>.
7312 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7314 m4_cdr of one-member list was [[]] (one-member list containing an
7315 empty string) instead of [] (an empty list. Callers were skewed to
7316 match this misbehaviour. As a consequence of this:
7317 - m4_foreach([x], [], [foo]) expanded to `foo', while
7318 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7319 This bug has been fixed:
7321 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7322 expand to an empty string; print error msg if called without
7324 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7325 misbehaviour; handle [] and [[]] correctly.
7327 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7329 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
7330 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
7331 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
7333 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7335 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7336 swallow records with more than 99 fields.
7337 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7338 parse the long line.
7340 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7342 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7343 swallow literals longer than 399. Reported by Ralf Wildenhues.
7344 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
7345 to workaround this limitation.
7347 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
7349 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7350 to gfortran, and make these the first two compiler names
7351 checked (following the general autoconf preference for gcc).
7353 2005-06-03 Stepan Kasal <kasal@ucw.cz>
7355 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7356 (DISTCLEANFILES): Remove $(check_SCRIPTS).
7357 (testsuite): Make sure autotest.m4f is up-to-date before using it.

7361 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7362 expression of unbounded size when processing the --list
7363 option. This runs afoul of a limit of 399 bytes per regular
7364 expression on AIX. Problem reported by Ralf Wildenhues.
7366 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

7369 * doc/autoconf.texi (Particular Headers): Reword example
7370 for multiline stdbool replacement.
7371 (Setting Output Variables): Reword text a bit. Don't
7372 give all the details about |#_!!_#|.
7373 Reword description of line replacement.
7375 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7377 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7378 now contain newlines, and substituted files must be referenced on
7379 a line alone; the sed scripts to substitute them are now very
7381 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
7382 commands can be put in a sed script portably.
7383 * doc/autoconf.texi (Setting Output Variables): Document above
7384 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
7385 use of multiline substitution.
7386 * tests/torture.at: No longer expect substitution of newline to fail.

7395 * tests/local.at: Don't attempt to check for negated character
7396 classes in shell scripts. The test was too brittle.
7398 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7400 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
7401 * doc/autoconf.texi (Limitations of Builtins): Document this
7404 2005-05-24 Stepan Kasal <kasal@ucw.cz>
7406 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
7407 common code; used in many places in the tree.
7408 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
7409 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
7411 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
7413 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
7414 messages when ac_unique_file is not found.
7415 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7416 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
7417 commands, for consistency with AC_MSG_ERROR and such.
7419 * bin/autoconf.as: Make more use of "shift 2" in option processing.

7429 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7431 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
7432 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7433 (ac_top_builddir): ... this ...
7434 (ac_top_build_prefix): ... to this; the old name is also kept, for
7435 backward compatibility.
7436 (ac_top_builddir_sub): New variable, without the trailing slash,
7438 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
7439 * doc/autoconf.texi (Configuration Actions): Rename
7440 ac_top_builddir to ac_top_build_prefix.

7452 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7453 argument to m4_foreach. I guess it was necessary in the past,
7454 but I think it's a no-op now.

7458 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7459 ``cat <<_ACEOF'' commands to one.

7465 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7467 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
7468 the wrong patterns between ``case'' and ``esac.'' The previous

7539 Also, throughout this document, be more careful about white space.
7540 "blank", "white space", and "space" all have different meanings
7541 and we should be careful to say what we mean.

7592 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7593 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7594 comment and reduce m4_default([foo], []) to [foo].
7595 (m4_strip): Update the explanation.
7597 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7599 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7600 Remove core.conftest.* too; it's generated by Tru64 5.1.
7601 Problem reported by Jennis Pruett.
7602 * lib/autoconf/functions.m4
7603 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7604 Don't bother to remove core files; AC_RUN_IFELSE should do that

7677 ac_pwd, and quote srcdir.
7678 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
7680 * doc/autoconf.texi: Fix some systematic formatting problems.
7681 ".)" needs a following @: if not at the end of a sentence, and
7682 similarly for "!)". "etc." should be preceded by a comma.
7683 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.

7699 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
7700 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
7701 from a Common Lisp's `cl'.
7702 (AC_PROG_CXX): Behave according to the documentation: don't
7703 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
7704 make the variable CCC precious; use `cl.exe', not `cl'.

7709 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
7710 /dev/null, as "configure" shouldn't read stdin, and this insulates
7711 us from problems (e.g., when testing for "cl"). Also, do this
7712 redirection before invoking "hostname" or "uname", and keep the
7713 original input stream available via...

7727 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
7728 newline if neither \c nor -n work, as that would output two

7733 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.

7739 Undo previous change, except keep the change to
7740 lib/autoconf/programs.m4 that replaced grep with shell

7749 Suggested by Alexandre Duret-Lutz. Also, do this redirection
7750 before invoking "hostname" or "uname".
7751 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7752 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.

7925 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
7926 Update the long comment explaining it.
7928 m4_require no longer writes an ``is required by'' line to the
7929 execution stack. It contains only one bit of non-redundant
7930 information: that the macro was required, not called. And even
7931 this bit is useless in most situations: have you ever met a macro
7932 which both calls and requires the same macro?
7934 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
7935 (_m4_defun_pro_outer): ... only via this macro, for the outermost

7982 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
7983 Warn about newline stripping in `` and $(). Update Solaris
7985 (Limitations of Builtins): Use expr "X...", not expr "x...", as
7986 X insulates us from future changes to Posix.

8035 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
8036 (_m4_divert_n_stack): New macro; the expansion is
8037 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
8039 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
8040 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8041 stored in _m4_divert_diversion or _m4_divert_dump.
8042 (m4_divert_pop): When the parameter is given, compare the symbolic
8043 name with the last diversion pushed on the stack. Previously, the
8044 current diversion was compared with the numeric value of the
8045 diversion given as the parameter.
8046 (m4_require): If the macro hasn't been expanded yet, call ...
8047 (_m4_require_call): this new macro.

8080 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
8081 signals that the package uses Automake; a `Makefile.am' is typical but
8082 not essential. Reported by Magnus Therning.

8559 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
8561 * doc/autoconf.texi (Function Portability): Document isinf and
8562 and isnan. From a suggestion by Kevin Ryde.
8564 * lib/Autom4te/General.pm (END): Return correct exit status even
8565 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
8567 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
8569 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
8570 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
8571 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
8573 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
8575 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
8576 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
8577 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
8578 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
8579 * lib/autom4te.in (Automake-preselections): Preselect
8580 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8582 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8584 * lib/autom4te.in (Automake-preselections): Preselect
8585 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
8588 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
8590 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
8592 * doc/autoconf.texi (Shellology): Mention BIN_SH.
8593 Document problem with "`""`" in pdksh POSIX mode.
8595 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
8597 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
8598 with pdksh, too. Problem reported by Patrick Welche via
8600 * doc/autoconf.texi (Shellology): Note that set -o posix is
8601 useful for pkdsh, too.
8603 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
8605 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8606 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8607 Don't fail if ENV or BASH_ENV is readonly.
8608 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
8609 etc. are read only. Problem reported by Ludovic Courtes.
8611 2004-06-23 Noah Misch <noah@cs.caltech.edu>
8613 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
8614 zsh, disable GLOB_SUBST to avoid backslash handling problems.
8617 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
8619 * doc/autoconf.texi (File System Conventions): Warn about
8620 names like "aux". Problem reported by Eric Blake.
8622 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
8623 by zero instead of array size, so that we can use any arithmetic
8624 constant expression (instead of requiring an integer constant
8625 expression). This allows us to test expressions like DBL_MAX <
8626 LDBL_MAX, which didn't conform to the C standard using the old
8628 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
8629 now that we can do floating-point tests at compile time.
8631 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8633 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8634 and LDBL_EPSILON, as the resulting expression isn't an
8635 integer constant expression and violates the C standard.
8636 Problem reported by Nelson H. F. Beebe. Also, check
8637 for "L" suffix, and check that long double doesn't have
8638 worse range or precision than double, that mixed-mode
8639 arithmetic doesn't generate a diagnostic, that double
8640 constants fit in long double.
8642 2004-06-03 Kevin Ryde <user42@zip.com.au>
8644 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
8645 malloc(0) and realloc(NULL,size).
8647 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
8650 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
8652 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
8653 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
8656 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8658 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
8659 can be rewritten using if-then-else. Suggested by Bruno Haible.
8661 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
8663 * doc/autoconf.texi (testsuite Scripts): Fix typo.
8664 Problem reported by Stepan Kasal.
8666 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8668 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
8669 change). Patch reported by Ralf Wildenhues in
8670 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
8672 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8673 function F exists if the compiler and linker let you compile an
8674 expression like (F != 0). Recent versions of GCC optimize away
8675 the reference to F in that case, since every function address must
8676 be nonzero, so the link succeeds even if F does not exist.
8677 Problem reported by Manu in
8678 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
8680 * doc/autoconf.texi (Systemology): Standardize on the spelling of
8681 "Unix". Many uses changed.
8682 (Limitations of Builtins): Explain better why the ! command isn't
8685 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
8687 * lib/autom4te.in (Automake-preselections): Preselect
8688 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
8690 2004-05-19 Kevin Ryde <user42@zip.com.au>
8692 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
8693 referencing AC_FUNC_STRERROR_R.
8695 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
8696 note pessimistic assumption when cross compiling.
8698 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
8700 * doc/autoconf.texi (Limitations of Make): Note that BSD make
8701 (until 2004) invoked subcommands with sh -e, contra POSIX.
8702 Reported by Kevin Ryde.
8704 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
8706 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
8707 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
8708 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
8709 `test -f " /usr/bin/grep"', which _always_ failed.
8710 (AC_PROG_SED): Ditto bogus PATH fix.
8711 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
8712 requires that grep correctly supports _multiple_ `-e' options, rather
8713 than stating only that grep should accept `-e'.
8715 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
8717 Port to C99, which requires that 'exit' be declared.
8719 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
8720 to ensure that stdlib.h is included.
8721 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
8722 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
8723 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
8724 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
8725 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
8726 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
8727 when using 'exit' in a test; C99 requires that 'exit' be declared.
8729 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
8731 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
8732 now prefers 'grep' implementations that accept -e.
8733 (Limitations of Usual Tools): Describe problems of traditional
8734 egrep and fgrep with long input lines, and of traditional grep
8736 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
8737 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
8738 All callers changed. Append /usr/xpg4/bin to the PATH, for
8740 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
8741 the user with complaints about multiple -e options.
8742 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
8743 Define it with AC_PROG_GREP.
8744 * configure.ac (AC_PROG_GREP): Add.
8745 * lib/freeze.mk (GREP): New macro.
8747 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
8749 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
8750 a possible candidate only after all others fail, rather than
8751 consulting it first. This improves backward compatibility by
8752 better reflecting the way shell selection occurred in previous
8753 versions of Autoconf, and should help to avoid triggering latent
8754 problems in other packages, such as the one in Automake where zsh
8755 is not handled robustly:
8756 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
8757 Although it is not Autoconf's responsibility to work around
8758 problems in Automake, it nevertheless makes sense to avoid
8759 introducing unnecessary incompatibilites.
8761 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
8762 Gary V. Vaughan <gary@gnu.org>
8764 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
8765 how deeply nested we are when a suitable tool is found, set the
8766 ac_path_TOOL_found flag.
8767 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
8768 nested we are in this macro. Break out of all 3 nested loops if
8769 ac_path_TOOL_found is set.
8771 2004-04-21 Gary V. Vaughan <gary@gnu.org>
8773 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
8774 of the _AS_PATH_WALK loop too if GNU flavor is found.
8776 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
8778 * doc/autoconf.texi (Limitations of Make): Update documentation
8779 for `$<'. New entry `Long lines', based on a report from Simon
8780 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
8781 paragraph about DJGPP, based on a mail from Richard Dawe.
8783 2004-04-20 Paul Eggert <eggert@twinsun.com>
8785 * tests/c.at (C keywords): Don't assume that GCC supports
8786 "restrict" and "inline", as sufficiently-old GCC versions do not
8787 (also, GCC configured to be in pedantic C89 mode does not).
8788 Problem reported by Sumit Pandya in:
8789 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
8791 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
8792 consider -g to work if it generates warnings when plain compiles
8793 don't. Problem reported by Braden McDaniel in:
8794 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
8796 * doc/autoconf.texi (Slashes): New section, to document a problem
8797 reported by Jim Meyering in:
8798 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
8800 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
8801 linker output files before linking, to work around IRIX 6 linker bug.
8802 Problem reported by Rainer Orth in:
8803 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
8805 2004-04-20 Gary V. Vaughan <gary@gnu.org>
8807 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
8808 best tool so far counter rely on the tool path variable name to
8809 avoid checks for one tool being affected by the results of running
8810 the length check on a previous tool.
8812 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
8813 match expression argument, as different greps have different
8814 regular expression flavours.
8815 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
8817 (AC_PROG_EGREP): Pass 'EGREP$'.
8818 (AC_PROG_GREP): Pass 'GREP$'.
8820 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
8822 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
8823 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
8825 2004-03-29 Paul Eggert <eggert@twinsun.com>
8827 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
8828 Types, Specific Compiler Characteristics, System Services,
8829 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
8830 etc. consistently instead of 'long', 'short', 'unsigned' etc.
8831 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
8832 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
8834 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

8836 AC_TYPE_OFF_T): Likewise.
8837 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
8840 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to

8843 2004-03-28 Paul Eggert <eggert@twinsun.com>
8845 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
8846 now defines HAVE_DECL_TZNAME if it is declared, when
8847 HAVE_STRUCT_TM_TM_ZONE is not defined.
8848 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
8849 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

8854 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
8855 superfluous backslashing of quotes (") in sed expressions;
8856 thanks to Paul Eggert.
8858 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
8860 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
8861 Fortran compiler is ifort, also added pghpf; thanks to Nelson
8862 H. F. Beebe for the bug report.
8864 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
8866 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
8867 quoted -cmdline argument in Portland Group compiler (bug
8868 reported by Jeffrey J. Barteet).
8870 2004-03-25 Kevin Ryde <user42@zip.com.au>
8872 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
8873 (Run Time): ... here, where it's now mentioned.

8907 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
8908 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
8909 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a

8912 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
8913 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
8916 2004-03-03 Paul Eggert <eggert@twinsun.com>
8918 * bin/Makefile.am (edit): Don't use $< in a context where
8919 POSIX doesn't require support for it. Use $@.in instead.
8920 Problem reported by Anthony N. Frasso in
8921 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
8922 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

8932 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
8933 is not always thread-safe. Report from Nathanael Nerode.
8935 2004-02-18 Paul Eggert <eggert@twinsun.com>
8937 Fix a dependencies problem, stemming from a Autoconf 2.59 build
8938 problem on QNX reported by Stephen Rasku in

8950 AC_SUBST provides no portable way to escape literal newlines.
8952 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
8953 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
8954 Darwin uses -lcrt2.o and there's little point to cataloging all
8955 the system variants. Partial fix reported by Andreas Waechter in:

8972 the behavior of the third argument.
8973 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
8974 correctly the behavior of the third argument. Document
8975 what the three macros that AU_DEFUN defines do. Fix
8976 warning message when the third argument includes $0
8977 (reported by Alexandre Duret-Lutz).
8979 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
8980 Eric Sunshine <sunshine@sunshineco.com>
8981 Paul Eggert <eggert@twinsun.com>
8983 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

8994 (_AS_RUN): Move it here, support testing with eval.
8995 (AS_REQUIRE_SHELL_FN): Require shell functions when
8997 (_AS_LINENO_WORKS): Put around braces, we do not
8998 trigger the bash bug anymore.
8999 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
9000 use AS_INIT_WITH_SHELL_FN.
9001 * bin/autoconf.in, tests/wrapper.in: Regenerated.
9003 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

9045 egrep and fgrep respectively if $GREP -E/-F don't work.
9046 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
9047 _AC_PROG_GREP, and AC_PROG_SED.

9080 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9081 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9082 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9083 not <inttypes.h>. Problem reported by Tim Mooney in
9084 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9085 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9088 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9089 otherwise "make check" fails because it forbids cmp (I guess
9090 because cmp treats files as binary on DOS-like systems).

9105 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9106 -std1 disables some useful extensions on Tru64. Problem reported

9110 2004-01-14 Paul Eggert <eggert@twinsun.com>
9112 * doc/autoconf.texi (Programming in M4sh): Document that
9113 AS_MKDIR_P succeeds if the destination is a symbolic link
9114 to an existing directory.
9115 (Limitations of Usual Tools): Note that mkdir -p might not
9116 succeed on symlinks to directories.
9118 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9120 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

9134 2004-01-09 Paul Eggert <eggert@twinsun.com>
9136 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9137 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9138 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9139 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9140 AC_COMPILE_IFELSE, since we now assume our caller invokes
9141 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9142 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9143 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9144 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9146 2004-01-07 Paul Eggert <eggert@twinsun.com>
9148 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9149 `"'...'"`, as it's confusing (and I suspect it may not work on
9150 some platforms). The code was incorrect anyway, as it assumed
9151 that \$ evaluated to itself in that context. Reported by
9152 Alexandre Duret-Lutz.
9154 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9156 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

9189 * Makefile.am (autom4te-update):
9190 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

9206 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9207 -c -o might not work. From a suggestion by Kevin Ryde.
9208 (C Compiler, Generating Sources, Limitations
9209 of Usual Tools, Limitations of Make, Making testsuite Scripts):

9222 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9224 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9225 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

9227 explanation clearer.

9238 * tests/atlocal.in: Store the result here.

9496 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
9498 2003-10-10 Andreas Schwab <schwab@suse.de>
9500 * bin/autoheader.in: Avoid empty first line in --version and
9502 * bin/ifnames.in: Likewise.
9504 2003-10-09 Paul Eggert <eggert@twinsun.com>
9506 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
9507 Issue a more-informative diagnostic.
9508 Problems reported by Eric Sunshine.
9510 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
9512 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
9513 -mGLOB_options_string stuff for Intel ifc, which can cause
9514 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
9515 pattern-matching instead of grep.
9517 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
9519 * doc/autoconf.texi: Document new FC Fortran macros.
9521 2003-10-08 Gary V. Vaughan <gary@gnu.org>
9523 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
9524 that future autopoint/aclocal/automake/autoreconf will be able
9525 to trace to find where to install local m4 macros.
9526 * doc/autoconf.texi (Input): Document it.
9529 2003-10-06 Gary V. Vaughan <gary@gnu.org>
9531 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
9532 -lcrtbegin.o to list of ignored flags and fix underquoting of
9535 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
9537 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
9538 cache variable instead of $G77 to decide whether to include -O2,
9539 since $G77 is specific to Fortran 77.
9541 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9543 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
9544 free" flag. Re-order flags tested into rough order of popularity.
9546 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9548 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
9549 arguments so that it can be used with syntax identical to
9550 AC_PROG_F77, and so that we can more easily decide to
9551 remove/deprecate the DIALECT optional argument in the future if it
9553 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
9554 non-freeform-supporting compilers. Document freeform flags.
9556 2003-10-03 Akim Demaille <akim@epita.fr>
9558 * configure.ac: Look for emacs, not macs.
9559 Reported by Eric Sunshine.
9561 2003-10-03 Akim Demaille <akim@epita.fr>
9563 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
9564 * bin/autoreconf.in (autoreconf_current_directory): Create the
9565 AUX_DIR if needed, for sake of automake --add-missing etc.
9566 Suggested by Alexandre Duret-Lutz.
9568 2003-10-03 Akim Demaille <akim@epita.fr>
9570 * configure.ac: Quotation and formatting changes.
9571 (EMACS): Don't set it if it is not recent enough to support
9575 2003-10-02 Akim Demaille <akim@epita.fr>
9577 * bin/ifnames.in (&scan_file): Skip C++ comments.

9599 (&news_file): Rename as...
9602 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
9604 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
9605 have been created when invoking the compiler.
9606 * tests/fortran.at (GNU Fortran 77): Quote $G77.
9608 2003-09-29 Akim Demaille <akim@epita.fr>
9612 * config/mkinstalldirs: Upgrade.

9616 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
9617 Problem reported by Lars J. Aas in
9618 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
9619 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
9620 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
9621 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
9623 2003-09-26 Akim Demaille <akim@epita.fr>
9625 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
9626 directory for AC_CONFIG_COMMANDS' first argument exists.
9627 This makes valid the invocation of _AC_SRCPATH that follows.
9628 Reported by Eric Sunshine.
9629 * doc/autoconf.texi (Configuration Commands): Adjust.
9631 2003-09-26 Akim Demaille <akim@epita.fr>
9633 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
9634 Reported by Ralf Corsepius.
9636 2003-09-26 Akim Demaille <akim@epita.fr>
9638 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
9640 Actually, use AU_ALIAS.
9643 2003-09-26 Paul Eggert <eggert@twinsun.com>
9645 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
9646 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
9647 Problem reported by Eric Sunshine in:

9650 2003-09-26 Akim Demaille <akim@epita.fr>
9652 The test suite are sometimes assigning timings incorrectly.
9653 Reported by Henk Krus.
9654 Diagnosed by Nicolas Joly.
9656 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
9658 Instead of making AT_help a sequence of assignments to grow
9659 $at_help_all, just make AT_help_all be the growing contents of
9660 $at_help_all, and make a single assignment in...
9662 (at_times_skip): Flip the meaning and rename as...
9664 (AT_INIT): When summarizing the test that ran, remove
9665 $at_times_file after use, and check it is present before trying to
9668 2003-09-25 Akim Demaille <akim@epita.fr>
9672 * bin/Makefile.am (edit): Handle '@configure_input@'.
9673 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
9674 (ifnames): chmod -w.
9675 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
9676 executables, not bin/ executables! Otherwise all the magic needed
9677 to find non installed files is turned off. This caused a failure
9678 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
9679 as found in its environment (sent by tests/autoreconf): pointing
9680 to bin/autom4te that could not find its files.
9681 * tests/mktests.sh: Force the replacement of generated files, for
9682 the sake of "mv" program that are interactive when overwriting a
9684 * config/install-sh: Upgrade from CVS Automake.
9686 2003-09-23 Paul Eggert <eggert@twinsun.com>
9688 * doc/autoconf.texi (Limitations of Builtins): Document test -h
9689 versus test -L issues.
9691 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
9692 Paul Eggert <eggert@twinsun.com>
9694 Trivial change to support GCC's configuration procedure.
9695 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
9696 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
9697 about inconsistency if the preprocessor is set to give errors for

9730 willing to edit the output files.
9732 2003-09-10 Akim Demaille <akim@epita.fr>
9734 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
9736 * tests/mktests.sh: Skip AC_FC_SRCEXT.
9737 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

9759 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
9760 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
9762 2003-09-04 Akim Demaille <akim@epita.fr>

9773 2003-09-04 Akim Demaille <akim@epita.fr>
9775 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
9777 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
9779 Add support for newer Fortran dialects. The F77 interface is
9780 unchanged, and continues to support Fortran 77. New FC macros
9781 correspond to all the old F77 macros, with output variables FC,
9782 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
9783 available dialect, but older dialects can be specified. There are
9784 new macros AC_FC_SRCEXT to set the source extension, and
9785 AC_FC_FREEFORM to accept free-form source files.
9787 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

9820 * tests/m4sugar.at (cross_warning): Make sure to enable the
9821 output, so that we can track spurious m4sugar output.
9822 * tests/local.at: Require 2.57.
9823 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
9824 are defaulted by AT_CHECK anyway.
9825 Use AT_CHECK_AUTOM4TE.
9826 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a

9901 Use &verb, not &verbose.
9903 2003-08-21 Akim Demaille <akim@epita.fr>
9905 * bin/autoheader.in (&parse_args): Use &parse_warnings and
9907 ($help): Use Autom4te::ChannelDefs::usage.
9908 * bin/autoscan.in: Use Autom4te::ChannelDefs.

9911 2003-08-21 Akim Demaille <akim@epita.fr>
9913 First stab at preserving warnings between calls to autom4te,
9914 including when the cache is used.
9916 There are still several issues: (i) there are too many runs of m4
9917 (one for include, one for warnings, and some more), (ii) warnings
9918 spreading on several lines are not handled gracefully, (iii) the
9919 code meant to have the call stack display for errors does not work
9920 (its handling should move from m4 to autom4te).
9922 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
9924 (@preselect): Add m4_warn.
9925 ($exit_status): Remove, use $exit_code.
9926 ($help): Use Autom4te::ChannelDefs::usage.
9927 (&handle_m4): No longer define the m4_warnings.
9928 At each run, extract and report the warnings.
9929 Always cache the result, including if the exit status is on
9930 failure, since if nothing changes, we should result in the same
9931 failure, hence we can use the cache.
9932 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
9933 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
9935 (m4_warn): Redefine as a do-nothing: it is its invocation that
9936 matters, as warnings are now reported via traces.
9937 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
9938 the contents of m4_warn: make it _call_ m4_warn, so that tracing
9939 the latter reveals calls to the former.
9943 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
9945 2003-08-21 Akim Demaille <akim@epita.fr>
9947 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

9969 2003-08-20 Akim Demaille <akim@epita.fr>
9971 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
9972 Reported by Alexandre Duret-Lutz.

9976 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
9977 * bin/autom4te: Adjust.
9978 In particular, be Autoconf tools are really silent when properly
9979 working, bind the verbosity of the 'note' channel to $verbose.
9980 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
9981 (&xsystem, &contents): Remove, since they are exported by...

10054 (AT_CHECK_NOESCAPE): Move core functionality to...
10055 (_AT_CHECK): ...this new macro.
10057 2003-08-07 Derek Price <derek@ximbiot.com>

10071 -lcrt1.o, for OS X. (trivial change)

10075 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
10076 inside '#ifndef __cplusplus'. Problem reported by
10079 2003-07-06 Bill Clarke <llib@computer.org>
10081 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10082 'long', not 'int', for benefit of Sun's recent C++ compilers
10083 (trivial change). See:
10084 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

10100 From Gareth McCaughan.
10102 2003-06-23 Akim Demaille <akim@epita.fr>
10104 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10105 not all of them. This fixes 1. the fact that when testing
10106 Autoconf there are many many config.log, 2. the incorrect use of
10107 top_srcdir to find config.log.
10108 Don't mix the detailed output of failed test with the summary of
10109 failures. Rather, append detailed log afterwards.
10111 2003-06-23 Akim Demaille <akim@epita.fr>
10113 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
10114 always run: output config.log on $at_group_log.
10116 2003-06-23 Akim Demaille <akim@epita.fr>
10118 * tests/torture.at (#define header templates): Don't use quotes in
10119 C++ comments as it puzzles Emacs' sh font-lock-mode.

10123 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.

10168 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.

10171 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
10172 (AT_INIT): Support for expected failures.
10174 2003-06-02 Akim Demaille <akim@epita.fr>
10176 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space

10183 2003-05-28 Paul Eggert <eggert@twinsun.com>
10185 * NEWS, doc/autoconf.texi (Particular Functions),

10191 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10192 (handle_exec_errors): New function. Work around $! being
10193 altered by WEXITSTATUS.
10194 (xqx, xsystem): Use handle_exec_errors.
10196 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10198 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10199 Do not call `_exit()', simply modify `$?'.
10200 (xsystem): Reset $! before running system, and check it afterward.
10201 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10202 63 for version mismatches.
10204 2003-05-23 Akim Demaille <akim@epita.fr>
10206 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10207 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10208 the middle of a line).
10209 * lib/m4sugar/m4sugar.m4: Likewise.
10210 Remove useless spaces in comments.
10212 2003-05-23 Akim Demaille <akim@epita.fr>
10214 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10215 exit 63, so that we (or Automake's "missing") can tell the
10216 difference with a plain failure.
10217 * doc/autoconf.texi (Notices): Adjust.
10219 2003-05-23 Akim Demaille <akim@epita.fr>
10221 * Makefile.am, bin/Makefile.am, config/Makefile.am,
10222 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
10223 White spaces cleanup.
10225 2003-05-22 Jim Meyering <jim@meyering.net>
10226 Paul Eggert <eggert@twinsun.com>
10228 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10229 Remove `#include <stdlib.h>' from the list; we should never
10230 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10231 resulting namespace pollution would cause other tests to fail.
10232 Configure scripts run with some older versions of g++ and HP's
10233 aCC would fail due to such an #include. Problems reported by
10234 Matthew Mueller in <http://bugs.debian.org/120704> and by
10236 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10237 In the test, use the test declaration before including <stdlib.h>,
10238 as that's closer to how it'll be used.
10240 2003-05-23 Akim Demaille <akim@epita.fr>
10242 * doc/autoconf.texi (Header Portability): ucred.h.
10245 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10247 Overhaul Autotest's logging: generate separate log files
10248 in testsuite.dir/NNN/testsuite.log, and append them to
10249 testsuite.log instead of re-running the test verbosely.
10251 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10252 file descriptor, write 0 to at_status_file instead of setting
10253 at_status=0, initialize some new variables (at_status_file,
10254 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10255 to rerun the tests, instead append the at_group_log to the
10256 at_suite_log when a test fails.
10257 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10258 with the AS_MESSAGE_LOG_FD redirected to stdout.
10259 (AT_CLEANUP): save the output status in $at_status_file
10260 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10261 its original place.
10262 (AT_CHECK): since tests are run with a redirected stdout,
10263 and used to be re-run in verbose mode, turn some $at_verbose
10264 into echo, and don't redirect the output of testing stdout
10267 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10268 the name of the debugging directory and information about
10271 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

10388 2003-05-06 Akim Demaille <akim@epita.fr>
10390 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10391 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10392 by aclocal.m4 is changed it might require the importing of another
10393 m4 extension file, i.e., aclocal must be run.
10395 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10396 (&parse_args): Use --force with aclocal if required and supported.

10410 2003-04-29 Derek Price <derek@ximbiot.com>
10412 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10413 seperator with m4_append_uniq(). It doesn't work.
10414 (AT_CLEANUP): Add `;' to end of at_help_all.
10415 (AT_INIT): Allow --keywords to be specified more than once. When
10416 grepping $at_help_all for keywords, use the field and keyword
10417 seperators to ensure a complete keyword match. Alter at_prev handling
10418 to support the new --keywords behavior.
10420 2003-04-27 Karl Berry <karl@freefriends.org>
10422 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10423 align better with others. I also made some of the individual
10424 entries on one line, for brevity and to make it easier for me to
10425 sort my dir-example file in the Texinfo distribution :).

10496 * tests/torture.at (Configuring subdirectories): Require aclocal
10497 1.4, otherwise the test fails, as it does support configure.ac.

10520 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
10521 obsolete AC_HELP_STRING.
10522 (AC_HELP_STRING): AU_DEFUN to...

10586 * bin/ifnames.in: Add final newline to help and version messages.
10588 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
10589 to cope with DOS-style absolute paths, when constructing
10592 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
10593 When constructing paths with IFS=:, quote the path. If we're
10594 constructing a DOS-style absolute path, we don't want to split it
10597 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
10600 2003-02-25 Pavel Roskin <proski@gnu.org>

10608 2002-09-01 patch by replacing "test -n" with "test -z".
10609 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
10610 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
10612 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,

10617 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
10618 format starting with "-".
10620 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
10622 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
10623 is not portable inside Makefile.
10625 2003-02-20 Akim Demaille <akim@epita.fr>
10627 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
10628 compiler says yeah, but preproc says nope, compiler is right.
10629 Conversely, prompt the reader to send a bug report to the
10630 maintainers of the package, not of Autoconf.
10632 2003-02-20 Klee Dienes <kdienes@apple.com>
10634 * bin/autoreconf.in (autoreconf_current_directory): Properly

10645 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10646 innocuous variant befor including <limits.h> or <assert.h>. This
10647 works around a bug reported by Albert Chin: HP-UX 11i
10648 (and earlier versions) have a <limits.h> that declares
10649 gettimeofday and many other functions.
10651 2002-12-03 Paul Eggert <eggert@twinsun.com>
10655 * NEWS, configure.ac: Update version.
10657 * doc/fdl.texi: Upgrade to FDL version 1.2.
10659 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
10660 nontrivially in main's body, so that f's external declaration is
10661 not optimized away in AIX. This should fix the bug reported by
10663 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
10665 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10666 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10667 defined, to support freestanding compilers. This should fix the
10668 bug reported by Momchil Velkov in
10669 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10671 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10672 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

10684 \(.*\) match is too long and there is something more to be checked.
10685 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

10703 Update from masters.
10705 2002-11-14 Akim Demaille <akim@epita.fr>
10707 * Makefile.maint: Sync with Bison, i.e.:
10708 (po-check): Scan .l and .y files instead of the
10709 .c and the .h files that they generate. This fixes the bug
10710 reported by Tim Van Holder in:
10711 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
10712 Look for N_ as well as for _. Try to avoid matching #define for
10716 2002-11-14 Akim Demaille <akim@epita.fr>
10718 * doc/autoconf.texi (C Compiler): Compiling several files at once.
10719 From Paul Eggert and Albert Chin-A-Young.
10721 2002-11-14 Akim Demaille <akim@epita.fr>
10723 * doc/autoconf.texi (C Compiler): Solitary backslashes.
10724 From Paul Eggert and Albert Chin-A-Young.
10726 2002-11-14 Kevin Ryde <user42@zip.com.au>
10728 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
10729 than assigning in main, to avoid HP cc +O3 optimizing it away.
10731 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
10733 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
10734 option. Process --recheck after parsing all options. Pass -q
10735 option to configure on --recheck.
10736 (AC_OUTPUT): Pass -q from configure to config.status.
10737 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
10738 arguments to record.
10739 * doc/autoconf.texi (config.status Invocation): Document
10740 config.status -q option.
10742 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
10744 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
10745 Makefile.in if Makefile.am exists.
10746 (output): Strip `.am' from Makefiles. Don't
10747 output AC_CONFIG_FILES if no Makefiles were found.

10767 Reported by Ezra Peisach.
10769 2002-11-05 Akim Demaille <akim@epita.fr>
10771 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
10773 We _have_ to stop using the old compatibility scheme that tried to
10774 avoid useless backslashes because Libtool 1.4.3 contains a
10775 AC_DEFINE([error_t], [int],
10776 [Define to a type to use for \`error_t' if it is not
10777 otherwise available.])
10778 We _have_ to quote the single quote and backslashes with \. The
10779 old compatibility scheme saw that ` was backslashed, and therefore
10780 did not quote the single quote. Hence before this patch, Autoconf
10781 was not compatible with Libtool.
10783 2002-11-04 Paul Eggert <eggert@twinsun.com>
10785 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

10802 (&autoreconf): here.
10803 ($help, $make, &parse_args, &autoreconf_current_directory):
10805 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10807 2002-10-31 Bruno Haible <bruno@clisp.org>

10823 2002-10-31 Akim Demaille <akim@epita.fr>
10825 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
10826 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
10827 Make variable, not a shell variable.
10828 Suggested by Bruno Haible.
10830 2002-10-31 Akim Demaille <akim@epita.fr>
10832 * bin/autom4te.in (load_configuration): Reject #args out of any
10835 2002-10-31 Akim Demaille <akim@epita.fr>
10837 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
10838 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)

10851 2002-10-29 Paul Eggert <eggert@twinsun.com>
10853 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
10854 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
10855 Problem reported by Bruno Haible.
10857 2002-10-29 Akim Demaille <akim@epita.fr>
10859 * doc/autoconf.texi (Header Templates): Put also in words what the
10860 pictures says to assist free style readers.
10861 (Customizing autom4te): s/--cache=/--cache /.
10863 2002-10-29 Akim Demaille <akim@epita.fr>
10865 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
10867 sparc_address_test returns void.
10868 Use it with an argument, as prototyped.
10871 2002-10-29 Akim Demaille <akim@epita.fr>

11172 Reported by Alexandre Duret-Lutz.
11174 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

11235 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11236 aclocal invocation, as Gettext macros might not be visible to
11238 Instead of blindly running autopoint, scan configure.ac (not the
11239 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11240 Reported by Paul D. Smith.
11242 2002-10-08 Paul Eggert <eggert@twinsun.com>

11249 * doc/autoconf.texi (Invoking autom4te):

11272 * tests/torture.at (Configuring subdirectories): Be robust to

11488 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11489 `duplicates', since the algorithm was too naive and could keep
11490 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11491 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11492 Reported by Ralf Corsepius.
11493 * tests/torture.at (Configuring subdirectories): Exercise these
11496 2002-09-09 Akim Demaille <akim@epita.fr>
11498 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
11499 looking for a replacement file.
11500 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11501 directory is relative.
11502 * doc/autoconf.texi (Generic Functions): Clarify the replacement
11503 directory definition.
11504 Reported by Andreas Schwab and Jim Meyering.
11506 2002-09-06 Akim Demaille <akim@epita.fr>
11508 * doc/autoconf.texi (Setting Output Variables): Clarify what
11509 precious variables are.
11510 Suggested by Pontus Skoeld.
11512 2002-09-05 Akim Demaille <akim@epita.fr>
11514 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11515 (ifnames, autoscan, autom4te): Since we don't only depend on
11516 configure.ac variables (such as VERSION etc.), but also on prefix
11517 and so forth, depend on Makefile, not configure.ac.
11518 Reported by Alexandre Duret-Lutz.
11519 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11521 2002-09-05 Kevin Ryde <user42@zip.com.au>
11523 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11524 doesn't seem to be confined to ia64, just say "some versions".
11526 2002-09-04 Akim Demaille <akim@epita.fr>
11528 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11530 * Makefile.am (maintainer-clean-local): Remove.
11531 (MAINTAINERCLEANFILES): Remove COPYING.
11533 2002-09-03 Paul Eggert <eggert@twinsun.com>
11535 * doc/autoconf.texi (Configuration Commands): Remove obsolete
11536 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
11539 2002-09-03 Akim Demaille <akim@epita.fr>
11541 * configure.ac: Bump to 2.53d.
11542 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11543 as of today, on Automake's team suggestion.
11545 2002-09-03 Akim Demaille <akim@epita.fr>
11549 2002-09-02 Akim Demaille <akim@epita.fr>
11551 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
11553 * configure.ac: Disable SITE_MACRO_DIR.
11555 2002-09-02 Jim Meyering <meyering@lucent.com>
11557 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11558 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11559 Also, tweak grammar: s/make sure to/be sure to/.
11561 2002-09-02 Paul Eggert <eggert@twinsun.com>
11563 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11564 directory names are generally preferable to physical names.
11566 2002-09-02 Akim Demaille <akim@epita.fr>
11568 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11569 Reported by Raja R. Harinath.
11570 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11571 * bin/autoupdate.in: Use error instead of die.
11573 2002-09-01 Paul Eggert <eggert@twinsun.com>
11575 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11576 ordinary shell concatenation rather than echo+tr+sed command that
11577 runs afoul of a long-line-related sed bug in Solaris 8.
11579 * bin/autoheader.in (parse_args): --warning -> --warnings.
11581 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11582 stdout, as traditional "ls" does.
11583 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11584 _AC_COMPILER_EXEEXT_O): Likewise.
11585 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11587 * bin/autoconf.as: Add --prepend-include option. This patch was
11588 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11589 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11591 * bin/autoconf.in, configure: Regenerate.
11593 * doc/autoconf.texi (Special Shell Variables): Mention
11594 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11596 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11597 MAILPATH and set PS1, PS2, PS4 to default values, to work
11598 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11599 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11600 the Autoconf documentation specifies; fall back to "unset" only if
11601 this fails. Use a shell for-loop for this rather than an m4 loop,
11602 to shorten the output script.
11604 2002-08-30 Paul Eggert <eggert@twinsun.com>
11606 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11607 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11608 for the CDPATH problem. Document PWD.
11609 (Limitations of Builtins): Document the problem that "cd $foo" and
11610 "ls $foo" may refer to different directories in shells conforming
11611 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11612 example, since the old example is now out of date.
11614 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11615 FOO" and "ls FOO" talk about different directories; this catches
11616 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11619 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11620 of rolling our own unset.
11621 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
11622 in practice we needn't worry about CDPATH if unset doesn't work.
11624 * Makefile.in, aclocal.m4, bin/Makefile.in,
11625 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
11626 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
11627 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
11628 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
11629 tests/Makefile.in: Regenerate with Automake 1.6.3.
11631 * config/config.guess, config/config.sub, config/mkinstalldirs:
11634 * configure: Regenerate with self.
11636 2002-08-30 Kevin Ryde <user42@zip.com.au>
11638 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
11641 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
11643 * bin/autom4te.in (Request::load): Correctly test for "do" read
11646 2002-08-29 Akim Demaille <akim@epita.fr>
11648 * lib/Autom4te/General.pm (&xqx): New.
11649 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11650 hand, which is not portable.
11652 * bin/autom4te.in: Use them.
11653 Use &error instead of die.
11654 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11657 2002-08-17 Paul Eggert <eggert@twinsun.com>
11659 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
11660 default list of compilers to try, since it was long ago superseded
11661 by the ksh fc builtin. Suggested by Steven G. Johnson.
11663 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
11665 * doc/autoconf.texi (Invoking autom4te): End the option table,
11666 fixing a bug introduced by the previous patch.
11667 (Limitations of Make): Add a 'target lookup' subentry in the
11668 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
11670 2002-07-29 Mark D. Roth <roth@feep.net>
11672 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
11673 options and use $AUTOM4TE_PATH.
11674 * doc/autoconf.texi: Remove documentation of autom4te
11675 --include-envvar and --site-macro-subdir options and document
11676 use of $AUTOM4TE_PATH.
11677 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
11678 arguments from each language section.
11680 2002-07-29 Paul Eggert <eggert@twinsun.com>
11682 * doc/install.texi: Include copyright symbol in copyright notice.
11684 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
11686 (AM_MAKEINFOFLAGS): New macro.
11687 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
11688 * Makefile.am (INSTALL): Use the new macros.
11689 Use -o rather than --output, since "missing" does not grok --output.
11691 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11693 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
11694 comments do not always work. Never trust the exit status of
11697 2002-07-24 Kevin Ryde <user42@zip.com.au>
11699 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
11700 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
11702 2002-07-23 Paul Eggert <eggert@twinsun.com>
11704 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
11705 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
11706 apparently treats PATH="nonexistent" as if it contained ".".
11707 Bug reported by Stefan `Sec' Zehl.
11709 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11711 * doc/autoconf.texi (Limitations of Make): Mention the special

11962 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
11963 version of Autoconf that is discussed.
11965 2002-05-22 Paul Eggert <eggert@twinsun.com>
11967 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
11968 from the default list of compilers to try. Suggested by
11970 * NEWS: Document the above.
11971 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
11973 2002-05-17 Paul Eggert <eggert@twinsun.com>
11975 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
11976 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
11977 This improves on an earlier suggestion by H. Peter Anvin.
11979 2002-05-16 Paul Eggert <eggert@twinsun.com>
11981 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
11982 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
11983 Both macros now accept an optional source-dir arg.
11984 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
11986 * NEWS: Document this.
11987 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
11989 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
11990 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
11991 not for GNU extensions; this undoes part of the 2000-11-03 change,
11992 reverting to 2.13-compatible behavior.
11993 Add new optional argument DIR.
11994 (AC_FUNC_FNMATCH_GNU): New macro.
11996 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
11998 2002-05-08 Paul Eggert <eggert@twinsun.com>
12000 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12001 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12002 and it causes a 'test' syntax error if it fails.
12003 Bug reported by Stephen Gildea.
12005 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12006 If prototypes are supported, use them to check this at compile-time,
12007 instead of trying to check it at run-time. If we must do a run-time
12008 check, assume that setvbuf is standard when cross-compiling, as
12009 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12010 Bug reported by Paul D. Smith.
12012 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12013 argument specifying location of getloadavg.c. This removes a
12014 FIXME. This idea was taken from Jim Meyering's implementation in
12016 * doc/autoconf.texi (Particular Functions): Document this.
12017 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12018 that's what the code does; this fixes a bug reported by
12021 2002-05-03 Akim Demaille <akim@epita.fr>
12023 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12024 autopoint instead of gettextize.
12025 ($uses_alocal): Rename as...
12026 ($uses_aclocal): this.
12027 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12028 Suggested by Bruno Haible.
12030 2002-05-03 Akim Demaille <akim@epita.fr>
12032 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12034 2002-04-29 Paul Eggert <eggert@twinsun.com>
12036 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12037 files to be 1 second older; just set them to be the same time.
12038 Also, sleep 1 second after the first aclocal, to work around
12039 problems with sub-second time stamps on the input files.
12041 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12043 * doc/autoconf.texi: Mention "set -e -x" lossage
12044 under node "Limitations of Builtins".
12046 2002-04-29 Akim Demaille <akim@epita.fr>
12048 * doc/install.texi: Better wording for setting variables when
12050 From Christian Cornelssen.
12052 2002-04-29 Akim Demaille <akim@epita.fr>
12054 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12055 of lack of $LINENO support, then the test will compare the $LINENO
12056 in testsuite vs. the lineno in the test file. This is wrong, of
12058 Be sure to protect it.
12059 Reported by Patrick Welche.
12061 2002-04-25 Akim Demaille <akim@epita.fr>
12063 * doc/autoconf.texi (Obsolete Macros): Typo.
12064 Reported by Vladimir Volovich.
12066 2002-04-25 Akim Demaille <akim@epita.fr>
12068 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12069 than some of the input files, hence, on the second run of aclocal,
12070 if some of its input are younger, make them older.
12071 Suggested by Paul Eggert.
12073 2002-04-25 Akim Demaille <akim@epita.fr>
12075 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
12076 Thanks to Paul Eggert.

12080 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12081 and ac_subst_vars be sh variables containing the list of
12082 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12084 (_AC_INIT_PREPARE): Use them to log them.
12085 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12086 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12087 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12088 _AC_SUBST_FILES and _AC_SUBST_VARS.
12089 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12091 2002-04-24 Akim Demaille <akim@epita.fr>
12093 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12094 autoheader, so that automake does not complain about a missing
12095 config.h.in that was to be created.
12097 2002-04-23 Akim Demaille <akim@epita.fr>
12099 * bin/autoheader.in (parse_args): --warning takes an argument.
12102 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
12104 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

12149 Minor spelling and grammar fixes.
12151 * doc/autoconf.texi: Follow the outline suggested in the GNU
12152 Sample Texts sections of the Texinfo 4.2 manual. Most
12153 importantly, this makes sure that the copyright notices appear in
12154 all output formats. You probably need Texinfo 4.2 to generate

12194 * doc/autoconf.texi (Shell Substitutions): Explain it.
12195 From Oliver Kiddle and Peter Stephenson.
12197 Have M4sh perform minimal shell sanitizing.
12199 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12201 (_AS_PREPARE): this new macro.
12203 (AS_INIT): Invoke AS_SHELL_SANITIZE.
12204 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
12206 Adjust Autoconf and Autotest.
12208 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12209 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12210 * lib/autotest/general.m4 (AT_INIT): Likewise.
12211 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
12212 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
12215 Use this M4sh to generate Autoconf's shell scripts.
12217 * tests/wrapsh.as: New, precursor of wrapsh.in.
12218 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12219 on Autotest and M4sh.
12220 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12221 (wrapsh.in): New target.

12237 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
12238 (Portable Shell): Cross reference to Systemology.
12240 2002-04-05 Akim Demaille <akim@epita.fr>
12242 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
12243 directories when descending in a SUBDIRS.

12246 2002-04-04 Andreas Schwab <schwab@suse.de>

12255 Use dnl, not the KILL diversion.
12257 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12258 (AC_CONFIG_LINKS): here.
12260 Don't use the KILL diversion, as it kills spurious output, which
12261 results in failures being hidden.
12262 Use m4_defn where appropriate.
12263 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12264 after the second argument.
12266 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12267 syntax, as it is provided by M4sugar.

12289 Integrate AC_PROG_CC_STDC into AC_PROG_CC.

12309 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12310 to avoid versions of HP C which don't allow that.
12312 2002-03-27 Paul Eggert <eggert@twinsun.com>
12314 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

12328 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12329 as POSIX requires, as it doesn't work with Zsh.
12330 * doc/autoconf.texi (Assignments): Document the problem.
12332 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12334 * doc/autoconf.texi (Limitations of Make): Mention more issue
12335 about VPATH, overriding of macros in sub-makes, and handling of
12338 2002-03-21 Paul Eggert <eggert@twinsun.com>
12340 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12341 problem with here-document buffer boundaries.
12343 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12344 when reinvoking the shell, to work around problems with installers
12345 who put strange things like "cd" commands in their environments.

12369 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12370 (Limitations of Usual Tools): Add mkdir section.
12372 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12373 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12374 back on AS_DIRNAME to compute prefixes otherwise; this is
12375 roughly what mkinstalldirs does. That way, we need not have
12376 our own filename disassembler. The old disassembler did not
12377 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12379 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12380 Create at_test_all by a series of assignments,
12381 not by a single assignment of a long string. The latter causes ksh
12382 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12383 presumably because of a buffer overrun.
12385 2002-03-14 Paul Eggert <eggert@twinsun.com>
12387 * lib/autotest/general.m4 (at_times_skip):
12388 Renamed from at_times. Now a boolean.
12389 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12390 says 'times: not found'.

12435 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12437 2002-03-08 Akim Demaille <akim@epita.fr>
12439 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12440 aliases the actual variables, and modifications of the former

12445 * bin/autom4te.in (&handle_m4): Protect us from corrupted file

12478 2002-03-04 Akim Demaille <akim@epita.fr>
12480 * doc/autoconf.texi (Transforming Names): Equality between target
12481 and host is irrelevant.
12482 (Specifying Names, Canonicalizing): Remove all references to the
12483 backward compatibility hooks. Rather, collect them all into...
12484 (Hosts and Cross-Compilation): this new section.
12485 * doc/install.texi (System Type): Ditto.
12486 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12487 that `--host' implies cross-compilation.
12489 2002-03-04 Akim Demaille <akim@epita.fr>
12491 * doc/autoconf.texi (Evaluation Macros): New.
12492 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12494 (_m4_foreach): Define the variant with immediate evaluation so
12495 that it contains exactly the items, not an expression which
12496 evaluation is the current item.
12497 (m4_re_string, m4_re_word): Don't over quote them.
12499 2002-03-04 Akim Demaille <akim@epita.fr>
12501 Instead of having stacking `shift's evaluated at the end, let
12502 `foreach' loops immediately evaluate them.
12504 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12505 $*. This is the n-th time I change my mind, but hopefully this is
12508 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12510 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12511 it was only a hack for m4_text_wrap.
12512 (m4_car2): Remove, replaced by...
12514 (_m4_foreach): Adjust.
12515 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12516 m4_bpatsubst for clarification.

12570 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

12607 2002-02-05 Akim Demaille <akim@epita.fr>
12609 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
12610 to make sure they are up to date when `check' is run.
12612 2002-02-05 Akim Demaille <akim@epita.fr>

12632 optional are the sum of the previous files on the command line'.
12633 Also, pass `--reload-state=' on them, so...
12634 (handle_m4): don't.

12636 (M4sh): Rely on M4sugar.

12674 2002-01-28 Akim Demaille <akim@epita.fr>
12676 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12677 AUTOTEST_PATH *after* it was set.
12678 Don't put `.' in the PATH: the user should be precise and `./' if
12679 needed. In addition, given that the test suite does some `cd', if
12680 `.' is in the path, the `tested programs' sections will report
12681 programs found in the test suite's directory, while during the
12682 tests (performed in their own directory), these programs are no
12683 longer visible. In other words, the results is confusing and
12685 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

12732 Autoconf::General::getopt with non valid options.

12736 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

12754 * tests/Makefile.am (package.m4): New.
12755 EXTRA_DIST it since its a source.
12757 2002-01-06 Akim Demaille <akim@epita.fr>
12759 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
12760 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
12761 and PACKAGE_BUGREPORT from here...
12762 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
12764 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
12765 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
12766 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
12767 * tests/tools.at (autoheader): Adjust.

12789 2001-12-14 Akim Demaille <akim@epita.fr>
12791 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
12792 trailing files, don't apply `-rf' to files which might not be
12793 created by configure (core, core.*, and *.core), but just `rm -f'.
12794 Suggested by Jonathan Kamens.
12796 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

12820 2001-12-12 Kevin Ryde <user42@zip.com.au>

12823 forbidden file descriptors table.
12825 2001-11-26 Akim Demaille <akim@epita.fr>
12827 * bin/autoscan.in (%c_keywords): Build it at top level.
12828 Map to 1 in order to simplify its uses.
12830 2001-11-26 Akim Demaille <akim@epita.fr>
12832 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
12833 Remove $filepath, useless.
12834 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
12835 variables, they are really part of the tokens.
12836 Split the input line on spaces and then look for tokens.
12837 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
12838 because of `lex$U.$(OBJEXT)'.
12839 (&scan_files): Use "@list" instead of join.

12845 Remove, replaced by...
12846 * tests/wrappl.in: Be common for all the Perl executables.
12847 In particular autoscan and autoheader want -I.
12848 * configure.ac: Adjust.
12849 * lib/autoscan/headers: errno.h is portable.
12851 2001-11-26 Akim Demaille <akim@epita.fr>
12853 * bin/autoscan.in (used): New.
12856 2001-11-26 Akim Demaille <akim@epita.fr>

12883 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
12884 top_srcdir, builddir and top_builddir.
12885 Use `at_*dir' relatively to the directory containing the
12886 suite, use `*dir' when relatively to the current group dir.

12895 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12897 * doc/autoconf.texi (Using System Type): Add an example of `case
12898 $host' usage so people quit using `case $target' everywhere.
12900 2001-11-22 Akim Demaille <akim@epita.fr>
12902 * doc/autoconf.texi (Installation Directory Variables): Englishoes
12903 spotted by Jim Meyering.
12905 2001-11-16 Paul Eggert <eggert@twinsun.com>
12907 This patch implements a `long double' suggestion by Oliver Kiddle.
12909 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
12910 static, to catch errors if the value isn't known at compile-time
12911 and the compiler supports dynamic arrays. Change its name from
12912 `_array_' to `test_array' to avoid potential name clashes.
12913 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
12914 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
12915 better than double. Catch a bug in GCC 2.95.2 x86.
12916 * doc/autoconf.texi (C Compiler): Document the above.
12919 2001-11-13 Akim Demaille <akim@epita.fr>
12921 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by

12925 2001-11-13 Akim Demaille <akim@epita.fr>
12927 * lib/autotest/general.m4 (AT_INIT): After having run the test
12928 group, go back to the initial directory, not to at_suite_dir.
12930 2001-11-13 Akim Demaille <akim@epita.fr>
12932 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
12933 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
12934 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
12936 (AT_CHECK_CONFIGURE): Use absolute paths.
12937 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
12938 The problem is still the old one: there is no means in M4 (that I
12939 know about) to create a defining macro, because there is no means
12940 to create `$1' etc., therefore, the defining macro ``swallows''
12941 all the arguments meant to the defined macro.
12943 2001-11-13 Akim Demaille <akim@epita.fr>
12945 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
12946 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in

12952 * lib/autotest/general.m4: Change `tests?' into `groups?' in
12953 variable names when referring to a single test group, or to
12954 `suite' when referring to the whole test suite.
12955 `at_last_test' is removed: m4 compute at_format itself.
12956 (at_stdout, at_stder1, at_stderr): New variables.
12957 (AT_CHECK): Use them.
12959 2001-11-13 Akim Demaille <akim@epita.fr>
12961 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
12963 Create `testsuite.dir/003/run' instead of `testsuite.003'.
12964 Do it as soon as a test fails, don't wait till the end of the test
12966 Don't remove $as_me.[0-9]*, since these files no longer exist.
12968 2001-11-13 Akim Demaille <akim@epita.fr>
12970 * tests/tools.at: Use absolute paths, since we are no longer run
12973 2001-11-13 Akim Demaille <akim@epita.fr>
12975 Now that tests are running in their own private dir, there is no
12976 need to list the files to remove at the end of tests groups.
12978 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
12979 (AT_data_files, at_data_files): Remove.
12980 (AT_CLEANUP, AT_DATA): Simplify.
12982 Remove the group dir if !debug && !failed.
12983 * tests/atspecific.m4: Adjust.
12985 2001-11-13 Akim Demaille <akim@epita.fr>
12987 Start a new layout for Autotest: `testsuite' creates
12988 `testsuite.dir' in which the at-check-line etc. files are to be
12989 found, and `testsuite.dir/003' where the test group 3 is run.
12991 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
12992 at_check_line_file, at_format, at_test_normalized, at_group_dir
12994 Create the directories.
12995 Use absolute paths for at- files.
12996 (AT_CHECK): Adjust.
12998 2001-11-11 Michael Matz <matz@kde.org>
13000 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13002 (m4_car): Properly quote arguments.
13004 2001-11-13 Akim Demaille <akim@epita.fr>
13006 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13007 with stricter rules on LIBOBJS.
13009 2001-11-12 Paul Eggert <eggert@twinsun.com>
13011 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13012 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13015 2001-11-12 Akim Demaille <akim@epita.fr>
13017 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13019 2001-11-12 Akim Demaille <akim@epita.fr>

13024 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13025 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13026 specify to what the macro should be defined (typically to 1).
13028 2001-11-12 Akim Demaille <akim@epita.fr>
13030 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13033 2001-11-12 Akim Demaille <akim@epita.fr>
13035 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13036 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13037 definition used by Automake where LEX is +/- "${missing} lex" and
13038 `missing' itself contains variables.
13040 2001-11-12 Akim Demaille <akim@epita.fr>
13042 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13043 Now that M4sh pushes BODY, the comments were output at the end of
13046 2001-11-08 Akim Demaille <akim@epita.fr>
13048 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13049 that we can trace macros from aclocal.m4.
13050 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13051 obsoleted, and redirect to the former anyway.
13052 Reported by Ralf Corsepius.
13054 2001-11-08 Akim Demaille <akim@epita.fr>
13056 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13057 processed only if present.
13058 * tests/torture.at (Configuring subdirectories): Use autoreconf
13059 instead of successive calls to autoconf.
13060 Add a nonexistent subdirectory to exercise the patch above.
13061 Reported by Ralf Corsepius.
13063 2001-11-08 Kevin Ryde <user42@zip.com.au>
13065 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13066 doesn't accept .S files.
13068 2001-11-07 Akim Demaille <akim@epita.fr>
13070 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

13072 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13073 * bin/autom4te.in (warn_forbidden): New.
13074 (handle_output): Use it.
13075 Read m4_pattern_forbid with messages.
13077 2001-11-05 Akim Demaille <akim@epita.fr>
13079 * bin/autom4te.in (--normalize): Remove.
13080 * lib/autom4te.in: Adjust.
13082 2001-11-05 Akim Demaille <akim@epita.fr>
13084 * tests/Makefile.am (testsuite): Rename this target as...
13085 ($(TESTSUITE)): this.
13088 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13090 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13091 the --prefix option, also remove it's argument.
13093 2001-11-05 Akim Demaille <akim@epita.fr>
13095 * doc/autoconf.texi (testsuite Invocation): Update.
13096 (Writing testsuite.at): Update.
13098 2001-11-03 Akim Demaille <akim@epita.fr>
13100 * doc/autoconf.texi: s/@code/@command/ where appropriate.
13102 2001-11-03 Akim Demaille <akim@epita.fr>
13104 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13105 (&file_name_is_absolute): New, wrappers around routines from
13107 Use and export them.
13108 (&find_configure_ac): Optionally take a directory where to look at.
13109 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13111 Default @ARGV to `.', not find_configure_ac.
13112 (&autoreconf): Argument is a directory.
13113 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13114 * doc/autoconf.texi (autoreconf Invocation): Update.
13116 2001-11-03 Akim Demaille <akim@epita.fr>
13118 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13119 (@export_forward_subs): New.
13120 Add basename, dirname, and fileparse.
13122 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13123 Don't look for aclocal flags if we already know aclocal is not
13125 Move aclocal.m4t only if it exists.
13126 Reported by Ezra Peisach.
13128 2001-11-03 Akim Demaille <akim@epita.fr>
13130 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13131 passed on command line, defaulting to ./configure.ac if present.
13132 (&maybe_autoreconf, File::Find): Remove, unused.
13133 (&autoreconf): If autoconf is not used, don't try to trace.
13135 2001-11-02 Akim Demaille <akim@epita.fr>
13137 * configure.ac: Bump to 2.52g.
13139 2001-11-02 Akim Demaille <akim@epita.fr>
13143 2001-11-02 Akim Demaille <akim@epita.fr>
13145 * config/config.guess, config/config.sub, doc/standards.texi:
13146 * config/lispdir.m4: Update from masters.
13147 * configure.ac: Bump to 2.52f.
13149 2001-11-02 Akim Demaille <akim@epita.fr>
13151 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13152 Don't run aclocal when aclocal.m4 is not from aclocal.
13154 Don't run libtoolize and gettextize if --install is not given.
13156 2001-11-01 Paul Eggert <eggert@twinsun.com>
13158 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13159 be invoked before _AS_LINENO_PREPARE.
13160 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13161 than character ranges.
13163 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13164 invoking AS_BASENAME. Set the locale variables to 'C' if
13165 possible, as POSIX requires this to get the traditional
13167 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13169 2001-10-31 Paul Eggert <eggert@twinsun.com>
13171 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13172 with {}, as that triggers a bug in Bash 2.05.
13174 (_AS_LINENO_PREPARE): Use Sed rather than
13175 Awk. Fix the sed prepass to work even if there are multiple
13176 instances of $LINENO on the same line. Do not substitute for
13177 other variables like $LINENOT. Do not check file dates; such a
13178 check is unreliable on sufficiently fast machines, and removing
13179 the check makes the code simpler and more reliable. Check for
13180 output and chmod failures.
13182 * doc/autoconf.texi (Special Shell Variables): Document
13185 2001-10-31 Akim Demaille <akim@epita.fr>
13187 * tests/Makefile.am (atconfig): Remove this target, Automake
13190 2001-10-31 Akim Demaille <akim@epita.fr>
13192 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13193 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13194 provided, while it is optional.
13195 * configure.ac: Adjust.
13197 2001-10-26 Paul Eggert <eggert@twinsun.com>
13199 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13200 lib/Autom4te/Struct.pm:
13201 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13204 * doc/autoconf.texi (Special Shell Variables): Document some
13205 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13207 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13208 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13209 eval $LINENO is not portable in practice.
13211 2001-10-24 Akim Demaille <akim@epita.fr>
13213 * lib/Autom4te/General.pm (backname): New.
13215 2001-10-24 Akim Demaille <akim@epita.fr>
13217 * m4/: Remove, merged into...
13220 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
13222 * doc/autoconf.texi (Shellology): Mention the problems with bash
13223 2.05's use of ANSI quoting in its `set' builtin.
13225 2001-10-22 Paul Eggert <eggert@twinsun.com>
13227 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13228 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13229 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13230 POSIX decided to standardize on the int flavor of strerror_r.
13231 Always do char* test, as there's no reason not to.
13232 Assign to a char* var, to catch strerror_r that returns int*.
13234 * doc/autoconf.texi (Particular Functions):
13235 Document the above changes. Also, document the fact that
13236 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13238 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13240 2001-10-20 Akim Demaille <akim@epita.fr>
13242 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

13245 2001-10-20 Akim Demaille <akim@epita.fr>
13247 * lib/Autom4te/General.pm (&update_file): If destination is
13248 unchanged, remove the source.
13249 (&up_to_date_p): Don't be verbose, be debug.
13250 * bin/autoreconf.in: No longer support --m4dir.
13251 (&autoreconf): Display the full path of the configure.ac we are
13253 Trace it only once.
13254 Be sure to honor --force with gettextize.
13255 Always run aclocal.
13256 * doc/autoconf.texi: Adjust.
13258 2001-10-20 Akim Demaille <akim@epita.fr>
13260 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13262 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13263 `intl' is already present, as it refuses unless --force.
13264 (&parse_args): Use -I, --include instead of the old Autoconf
13266 ($localdir, $autoconf_dir): Remove.
13268 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13270 2001-10-19 Jens Petersen <petersen@redhat.com>
13272 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

13282 2001-10-19 Akim Demaille <akim@epita.fr>
13284 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a

13288 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
13290 * bin/autoreconf.in (autoreconf): Display the path to the
13291 configure.ac being studied.
13293 2001-10-18 Paul Eggert <eggert@twinsun.com>
13295 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13296 long, to work around a bug in the HP C compiler version HP92453-01
13299 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13300 (AS_BASENAME_EXPR): New macro.
13301 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13302 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13303 and fall back on 'sed' only if the other two fail. This makes
13304 AS_BASENAME act more like AS_DIRNAME.
13305 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13306 contains white space.
13307 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13308 Use AS_DIRNAME, since I think it's now DOS-friendly.
13309 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
13310 Allow "dirname //FOO" to return either / or //, as POSIX allows
13313 2001-10-10 Akim Demaille <akim@epita.fr>
13315 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

13321 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

13450 shell does not support LINENO, and if CONFIG_SHELL is unset or
13451 empty, and if we can find a shell that does support LINENO,
13452 then set CONFIG_SHELL to that shell and then re-execute
13453 ourselves with CONFIG_SHELL.

13457 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

13500 compatibility with POSIX shells.

13577 * doc/autoconf.texi (autoconf Invocation): Fix the example:
13578 AC_TRY_RUN is about compilation, not shell commands.

13621 Don't compute at_srcdir nor at_top_srcdir.

13683 * tests/Makefile.am (package.m4): Remove.
13685 2001-09-22 Akim Demaille <akim@epita.fr>

13758 2001-09-19 Akim Demaille <akim@epita.fr>
13760 * lib/autotest/general.m4: Englishoes.
13761 From Tim Van Holder and Alexey Mahotkin.

13765 * doc/autoconf.texi (Common Shell Constructs): New node,
13766 documenting AS_DIRNAME.
13767 (Limitations of Usual Tools): Refer to it when discussing dirname.
13768 Also, update discussion of POSIX standard to reflect latest draft.
13770 * lib/autoconf/c.m4:
13771 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
13773 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13774 Do not pass a first argument with leading '-'
13775 to expr, by parenthesizing initial integers that might be negative.
13777 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
13778 now merely checks whether it is an error to pass an argument
13781 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
13782 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
13783 whether it is a (compile-time) error to pass an argument to
13784 getpgrp. This simpler test supports the revised documentation,
13785 and is all that AC_FUNC_GETPGRP's users really need.
13787 2001-09-18 Akim Demaille <akim@epita.fr>

13799 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
13801 Add test for AS_BASENAME.
13802 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
13803 added test. It now correctly handles /1/2/3/, returning '3' not ''.
13804 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
13805 * tests/base.at: Fixed the expected responses. The old ones were
13807 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
13808 the documentation claims it should (and how it behaved in 2.13).
13810 2001-09-18 Akim Demaille <akim@epita.fr>
13812 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
13813 the AC_CONFIG_COMMANDS invocation.
13814 This also solves the name clash problems.
13815 Don't set the package's ID.
13816 * lib/m4sugar/Makefile.am (version.m4): Revamp.
13817 No longer to be shipped.
13818 (version.in): Remove.
13819 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
13820 * lib/autoconf/status.m4: Adjust.
13821 Use `m4_PACKAGE_STRING'.
13822 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
13823 the only optional argument is the name of the test suite.
13824 Expect `package.m4' to define the package signature.
13825 * lib/autom4te.in (Autotest): Add `package.m4?'.
13826 * tests/Makefile.am (package.m4): New.
13827 * tests/suite.at: ifnames is a victim.
13829 2001-09-18 Akim Demaille <akim@epita.fr>
13831 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
13832 AC_LIBSOURCE, AC_CONFIG_FILES.
13833 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
13834 program version string doesn't match the package's.
13835 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
13838 2001-09-17 Paul Eggert <eggert@twinsun.com>
13840 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13841 Allow expression to return any value that can fit into unsigned long
13842 (not int, as before). Check for output errors.

13846 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13847 Always include <stdio.h> and <stdlib.h>. Evaluate
13848 the expression in an extra function before these includes. Call
13849 fprintf "%d" only after ensuring the argument is of type 'int'.
13850 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
13852 2001-09-17 Paul Eggert <eggert@twinsun.com>
13854 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
13855 or CFLAGS=-O5. In that case, the linker has a relaxed view of
13856 fatal errors, and AC_CHECK_LIB causes it to include libraries even
13857 when they don't exist.
13859 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
13860 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
13863 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
13864 version with the version used by fileutils 4.1, except use
13865 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
13868 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
13870 2001-09-13 Akim Demaille <akim@epita.fr>

14022 2001-09-05 Akim Demaille <akim@epita.fr>

14025 the maintainer is dumb enough to do that...
14027 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14028 excellence in M4 quotation: consider `__file__' is active.

14101 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

14208 find the executables for it.

14210 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14212 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14213 indeed related to running the test suite, while passing
14214 --autoconf-dir and others is related to running non installed

14217 * tests/autoscan: New.
14218 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

14237 2001-08-29 Akim Demaille <akim@epita.fr>

14800 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
14802 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the

14819 No need to remove the files before and after the each test, before
14820 each test and at the end of the suite is enough.
14821 Display only the children `times', not the shell's.
14822 If the test failed or was skipped, at-times is not available.
14824 2001-08-07 Akim Demaille <akim@epita.fr>
14826 Always produce testsuite.log, including when there are no

14837 The use of `dumpstat' revealed that `len' was used although it
14838 should not. m4_text_wrap was using it, but in the Autoconf world
14839 where it is legal. Hence (i) test M4sh in its own world, not
14840 Autoconf's, and (ii), ahem, fix the bug :)
14842 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
14843 does not like `' instead of [].
14844 (AT_INIT): Forbid `^_?AT_'.
14845 And don't output such tokens.
14846 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',

14877 * bin/autom4te.in (@Request::includes): Remove, unused.

14886 2001-08-04 Akim Demaille <akim@epita.fr>
14888 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&

14910 first check that the trace cache file is up to date, and then
14911 compare its timestamp with that of the output.
14913 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
14914 the preamble. Don't require 5.005 as Autom4te::General does it,
14915 and better yet (use `use', not `require'!).
14916 * lib/Autom4te/Struct.pm: Rename the last occurrences of
14917 Class::Struct as Autom4te::Struct.
14918 * lib/Autom4te/General.pm (File::stat): Use it.
