763 Properly handle funny file names for headers in config.status.
764 The test suite did not cover this bug because the code was not
765 quoting properly the arguments of `rm -f' (which "fails" silently)
766 as well as the arguments of `diff' (whose output was redirected to
767 /dev/null so we couldn't see its error message).

875 BSD behavior on binary input.
877 Minor testsuite improvements.
878 * lib/autotest/general.m4 (AT_INIT) <PREPARE_TESTS>: Use fewer
879 forks when sanitizing PATH. Always output machine information,
880 not just when atconfig was located.
882 Add 'testsuite -C dir'.
883 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
885 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
887 <DEFAULTS>: Delay computation of variables based on $at_dir...
888 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
889 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
890 <PARSE_ARGS>: Parse new option.

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

911 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
913 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
914 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
915 mode, we change to the source directory, also set $ac_pwd so we
916 do not go back to the build tree for the next config subdir.
917 * tests/torture.at (Deep Package): Extend test to contain two
918 config subdirs on the top level.
920 Fix parallel `maintainer-check'.

952 check_SCRIPTS. Building the wrappers for `all' allows help2man
953 to use them for the manpages.
954 Report by Benoit Sigoure.
956 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
958 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

994 * tests/base.at (Input/Output): Likewise.
995 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
996 config.guess, and config.sub to test source tree.
997 Drop AC_CONFIG_AUX_DIR setting.
998 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
999 * tests/torture.at (Substitute a 2000-byte string): Drop
1000 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1001 (Substitute a newline, datarootdir workaround): Likewise.
1002 (Define a newline): Adjust for linenumber changes in configure.ac.
1003 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
1005 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
1006 if `pwd` contains whitespace.
1008 Quote $abs_top_srcdir in tests.
1009 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1010 * tests/tools.at (Syntax of the shell scripts): Likewise.
1012 * tests/m4sh.at (LINENO): Quote $0.
1014 Fix testsuite program wrapper for whitespace in `pwd`.
1015 The problem here is that the usual mantra is that command
1016 variables can contain arguments, thus we cannot just escape
1017 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1018 $top_builddir/tests directory early in $PATH, so that the
1019 wrappers are found by their plain name.
1020 * tests/wrapper.as: Put $testdir early in $PATH.
1021 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.

1033 <at_func_create_debugging_script, Driver Loop>:
1034 Quote $at_group_dir.
1035 * tests/autotest.at (whitespace in absolute testdir): New test.
1037 * lib/autom4te.in: Quote @datadir@.
1039 Proper file name escaping in Autoconf programs and Perl modules.
1040 This includes escaping of characters special to the shell
1041 as well as special to Perl, e.g., leading `<' or `>'.
1042 For example, when $file starts with `>', `open ">$file"'
1043 wrongly tries to append to a different file.
1044 * bin/autoconf.as: Fix quoting for autom4te options.
1045 * lib/Autom4te/General.pm (shell_quote): New function, taken
1046 from coreutils, written by Jim Meyering.
1048 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1050 * bin/autoreconf.in (parse_args): Likewise.
1051 * bin/autoscan.in (main): Likewise.
1052 * bin/autoupdate.in (main): Likewise.
1053 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1054 * bin/ifnames.in: Likewise, XFile usage fixes.
1055 * tests/tools.at (autom4te and whitespace in file names): Extend
1056 test. Test twice, with special characters allowed on w32, and the
1057 rest. Test leading and trailing whitespace, for `open_quote'.
1058 (autotools and whitespace in file names): New, analogous test.
1059 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1060 by Russ Allbery and Eric Blake.
1063 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1064 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1065 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1066 (update_file, contents): Use it.
1068 * Makefile.am (autom4te-update): Rewrite for git.

1072 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1074 Fix copyright years.
1075 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1076 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1078 2007-12-04 Eric Blake <ebb9@byu.net>
1080 Manually resync with gnulib, since 'make cvs-update' no longer works.
1081 * build-aux/config.guess: New upstream version.
1082 * build-aux/config.sub: Likewise.
1084 When using older automake, don't downgrade build-aux/texinfo.tex.
1085 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1086 * doc/Makefile.am (TEXINFO_TEX): Add.
1088 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1090 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1091 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1092 #undef as this runs afoul of our new way of creating config.h.
1093 Problem reported by Jim Meyering in
1094 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
1096 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1098 Fix autom4te for unusual characters in input file names.
1099 * bin/autom4te.in (files_to_options): Quote active characters
1101 * tests/tools.at (autom4te and white space in file names):
1104 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1105 Document that Tru64 awk always splits $0.
1107 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1109 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1110 `#AT_STOP_...' line at the end of each test.
1112 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1114 * lib/autotest/general.m4 (AT_INIT): For awk line number
1115 extraction script, ensure `$at_group' has a defined value
1116 even for the empty set, and properly quote its usage inside
1119 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1121 * doc/autoconf.texi (Shell Functions): New chapter. Document
1122 IRIX sh $0 issue in functions, move content from ...
1123 (Portable Shell): ... here.
1124 (Shell Script Compiler): Note that shell functions are not
1125 totally unportable any more.
1127 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1128 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1130 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1131 extracting the line numbers of the last needed test.
1133 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1135 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1138 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1140 Fix IRIX testsuite debugging failures: $0 in functions.
1141 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1142 Do not use $0 inside a function, as IRIX sh will set that to the
1143 function name rather than the script invocation name.
1145 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1146 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1148 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1149 to extract test scripts.
1150 (AT_INIT): Extract and cache test script line numbers.
1152 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1154 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1155 subsequent fixups; the awk -> here-document conversion trashes
1156 performance too much with AIX sh.
1158 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1160 * tests/local.at: Do not test m4, perl with AT_TESTED.
1162 Diagnose and guard against write errors dealing with config.status.
1163 The general idea is this: all write failures from `configure'
1164 writing `config.status' are indicated by $ac_write_error, which
1165 is only checked at the end. This is safe because config.status
1166 code is not executed before the file is complete. Other write
1167 failures, be they inside config.status, or in sub shell/awk
1168 scripts spawned from configure or config.status, typically need
1169 earlier checking, as their results are used right afterwards.
1170 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1171 before writing config.status, check afterwards.
1172 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1173 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1174 Set `ac_write_error' for write failures to config.status. Barf
1175 upon write failures to temporary files.
1176 Adjust note about closing and reopening the here-document.
1177 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1178 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1179 reopening the here-document.
1180 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1181 Ensure `ac_write_error' does not escape into config.status.
1182 Also, add a couple of code paths not yet exercised in the test
1183 suite: a config file with input from stdin, and a config header
1185 Suggestion for catching write errors by Bruno Haible.
1187 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1189 Avoid error with Tru64 awk and testsuite lines with many words.
1190 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1191 reads the testsuite, set the field separator to an unusual value,
1192 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1193 even splits the input if $i, i>0, was never accessed in the script.
1195 Revert 2007-10-17 change.
1196 * TODO: Multiline args in config files and headers mean something
1197 different and are not fixed, see
1198 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
1199 Report by Stepan Kasal.
1201 * doc/autoconf.texi (Generic Programs): Fix typo.
1203 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1205 AC_*_TOOL does not canonicalize the prefix
1206 * doc/autoconf.texi (Generic Programs): Do not say that
1207 the *_TOOL macros canonicalize, they simply use the `host_alias'.
1209 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1211 Diagnose write errors in config.status instantiations.
1212 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
1213 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
1215 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1216 Extend test to also check for some write error failures, using...
1217 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
1218 Report by Bruno Haible.
1221 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
1223 (_AT_CHECK): Use less indentation, to save space.
1225 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1227 Add witness macro for @top_build_prefix@ substitution.
1228 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
1229 (_AC_OUTPUT_FILE): Mention it here.
1231 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
1232 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1234 * lib/autotest/general.m4 (at_func_test): Remove.
1235 (AT_INIT): Pre-extract test groups into separate files.
1236 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
1237 Remove at-test-source files together with the $at_group_dir.
1238 * tests/autotest.at (Long test source lines): New test.
1240 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1242 Shell functions and variables may share a namespace.
1243 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
1246 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
1248 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
1251 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1253 * lib/autoconf/status.m4: Fix a couple of comment typos.
1255 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1257 2007-11-13 Jim Meyering <meyering@redhat.com>
1259 Clean up the rule to create "expr".
1260 * tests/Makefile.am (expr): Don't redirect directly to target.
1261 Redirect just once, not for each echo statement.
1262 Use $@, not literal "expr".
1264 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1266 Don't worry about preprocessor when testing long long.
1267 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1268 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1269 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1270 These no longer check for preprocessor flaws.
1271 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1272 Do not check for preprocessor flaws.
1274 2007-11-13 Jim Meyering <meyering@redhat.com>
1276 Adapt dependencies, now that a version change doesn't modify configure.ac
1277 * GNUmakefile: Remove "make clean" kludge.
1278 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1280 Don't redirect directly to target.
1281 Use $@, not literal "version.m4".
1283 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1285 * doc/autoconf.texi (Making testsuite Scripts): Document
1286 ":;{" shorthand as in previous patch.
1288 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1290 * doc/autoconf.texi (Limitations of Builtins): Document problem
1291 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1293 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1294 Use ":;{" shorthand.
1295 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1297 2007-11-12 Jim Meyering <meyering@redhat.com>
1299 Add more non-srcdir build support.
1300 * GNUmakefile (dummy): Split a long line.
1301 Add -v option to autoreconf invocation.
1303 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1304 * GNUmakefile (dummy): Remove INSTALL.
1306 Remove racy commands to build scripts in bin/ and tests/.
1307 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1308 are guaranteed to be built, remove the rules that tried to build
1309 them. Before, with a parallel build, these rules could lead to
1310 two processes writing tests/wrapper.in concurrently.
1312 Build in man/ only *after* building in bin/ and tests/.
1313 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1314 in both bin/ and tests/.
1316 Accommodate non-srcdir build-from-checkout.
1317 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1318 Use git's --git-dir=$srcdir/.git option.
1319 Add quotes, in case tarball_version_file contains shell meta-characters.
1320 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1321 * configure.ac: Pass "." to git-version-gen.
1323 Avoid spurious test failures due to version skew.
1324 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1326 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1328 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1329 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1330 Remove conftest.dSYM directory.
1331 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1332 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1333 Remove `conftest.*' recursively.
1334 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
1335 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1337 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
1339 Report and analysis by Jeff Squyres and Peter O'Gorman.
1341 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
1343 Fix typos in variable names.
1344 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
1346 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
1348 Document that $((expression)) is not portable.
1349 * doc/autoconf.texi (Shell Substitutions): Here.
1351 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1353 Ignore configure --help* errors due to LINENO-impaired shells.
1354 * tests/torture.at (Configuring subdirectories, Deep Package):
1355 In the --help* tests in read-only trees, make `.' temporarily
1356 writable again for the `stderr' file, and ignore errors due to
1357 the attempt to write configure.lineno.
1358 Report by Patrick Welche.
1360 2007-11-10 Jim Meyering <meyering@redhat.com>
1362 Generate package.m4 in build-dir, not srcdir.
1363 * tests/Makefile.am (package.m4): Adjust target.
1364 Don't redirect directly to $@.
1365 (CLEANFILES): Add package.m4.
1366 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1368 When running $(AUTOTEST), search "." before searching $(srcdir).
1370 Avoid a race condition that would make parallel "distclean" fail.
1371 * tests/Makefile.am (distclean-generic): Replace the default,
1372 automake-provided rule with an identical one, but with an additional
1373 dependency on distclean-local. Simply adding the dependency would
1374 cause automake not to emit the rule at all.
1375 * BUGS: Building with -jN works, now.
1377 Distribute git-version-gen.
1378 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1379 since GNUmakefile is distributed, and requires it for dist* rules.
1381 Remove two more generated files from version control.
1382 * INSTALL: Remove generated file.
1383 * lib/autoscan/autoscan.list: Remove generated file.
1385 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1387 * GNUmakefile (PATH): Remove stray apostrophes; they become
1388 part of PATH, which isn't wanted here.
1390 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1392 New config files output variable `top_build_prefix'.
1393 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1395 * doc/autoconf.texi (Preset Output Variables): Document it.
1397 Report by Bob Friesenhahn.
1399 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1400 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1401 function, to parametrize arithmetic with expr vs. the shell.
1402 Use it where possible.
1403 Suggestion by Benoit Sigoure.
1405 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1407 Adjust the documentation of autotest WRT atlocal.
1408 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1409 when using Automake, to write a rule to produce atlocal, since it's
1410 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1411 distributed, not atconfig.in.
1413 2007-11-04 Eric Blake <ebb9@byu.net>
1415 Update list information.
1416 * README: Mention new autoconf-commit list.
1417 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
1419 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1421 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
1423 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1425 * build-aux/.gitignore: Ignore mkinstalldirs.
1427 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1429 2007-11-03 Jim Meyering <meyering@redhat.com>
1431 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1432 * build-aux/git-version-gen: This syncs from coreutils.
1434 Adjust the build procedure so "make check" works reliably.
1435 * README-hacking: Include an extra step between "make" and
1436 "make check" to ensure that the latter passes.
1438 Use just-built tools, when possible.
1439 * GNUmakefile (PATH): Set and export here, ...
1440 (dummy): ... rather than here.
1442 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1443 and Andreas Schwab <schwab@suse.de>
1445 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
1448 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1450 * configure.ac (AC_PREREQ): Require version 2.60, for
1451 AC_PROG_SED, AC_PROG_GREP.
1453 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
1454 and Jim Meyering <meyering@redhat.com>
1455 and Andreas Schwab <schwab@suse.de>
1456 and Eric Blake <ebb9@byu.net>
1458 Document a bug in GNU Bash with compound commands and redirections.
1459 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
1460 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
1463 2007-11-03 Eric Blake <ebb9@byu.net>
1465 Support m4 1.4.5 in testsuite.
1466 * tests/torture.at (Define a newline): Exclude line numbers in
1468 Reported by Ralf Wildenhues.
1470 2007-11-03 Jim Meyering <meyering@redhat.com>
1472 Remove automake-provided files from version control.
1473 * build-aux/elisp-comp: Remove file.
1474 * build-aux/install-sh: Remove file.
1475 * build-aux/missing: Remove file.
1476 * build-aux/mdate-sh: Remove file.
1477 * build-aux/.gitignore: New file.
1478 Suggestion from Ralf Wildenhues.
1480 2007-11-03 Eric Blake <ebb9@byu.net>
1482 Adjust version comparison to account for git snapshot numbers.
1483 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
1484 component separator.
1485 * doc/autoconf.texi (Number processing Macros)
1486 <m4_version_compare>: Document this change.
1487 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
1489 2007-10-30 Bruno Haible <bruno@clisp.org>
1491 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1492 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1493 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1494 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1495 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1496 Suggested by Paul Eggert.
1498 2007-10-28 Jim Meyering <meyering@redhat.com>
1500 * README-hacking: Autoconf, Automake, and Perl are required to build.
1501 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1503 2007-10-28 Jim Meyering <meyering@redhat.com>
1505 README-hacking: Recommend running autoreconf -vi.
1506 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1507 so that we use just-built tools when they're available.
1508 Suggestions from Ralf Wildenhues.
1510 2007-10-28 Jim Meyering <meyering@redhat.com>
1512 Make inter-release --version output more useful.
1514 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1515 which indicates that it is built using the 19th change set
1516 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1517 is a prefix of the commit SHA1.
1518 * build-aux/git-version-gen: New file.
1519 * configure.ac: Run it to set the version.
1520 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1521 * Makefile.am (dist-hook): Arrange so that .version appears only
1522 in distribution tarballs, never in a checked-out repository.
1523 * .gitignore: Add .version here, too. Just in case.
1524 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1525 not configure.ac, now that the version number changes automatically.
1527 Ensure that $(VERSION) is up to date for dist-related targets.
1528 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1529 git-version-gen doesn't match $(VERSION), but only for dist targets.
1531 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1539 Remove all generated files from version control.
1540 * aclocal.m4: Remove.
1541 * configure: Remove.
1542 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
1543 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
1544 * README-hacking: New file: how to build from just-checked-out sources.
1546 2007-10-23 Eric Blake <ebb9@byu.net>
1548 Improve corner case of m4_expand.
1549 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more

1552 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
1555 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>

2805 for C++; this drops support for anonymous struct and union types,
2806 which were problematic anyway.

2826 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
2827 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
2828 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
2829 works but the latter doesn't, then it's a valid type.
2830 This lets people use function types and so forth.
2831 For C++ there doesn't seem to be a simple solution, so leave it alone.
2832 (AC_CHECK_SIZEOF): Allow argument to be a variable.
2833 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
2834 AC_CHECK_TYPE; that wasn't documented or necessary.

3043 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3045 * doc/autoconf.texi: Fix some typos.
3047 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
3049 Fix some wording problems noted by Paolo Bonzini in:
3050 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3051 * doc/autoconf.texi (Signed Overflow Examples): Give more
3052 discussion about the allow_superuser_privileges example,
3053 and change it a bit to make things clearer.
3054 (Optimization and Wraparound): Clarify whether the compiler
3055 will generate an infinite loop for the example derived from
3056 Autoconf's mktime test.
3057 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3058 Also, clarify unsigned multiplication overflow.
3060 2007-01-04 Eric Blake <ebb9@byu.net>
3062 * bin/Makefile.am (RELEASE_YEAR): New macro.
3063 (edit): Use it to supply correct copyright year to scripts.
3064 * bin/autoconf.as (version): Use it.
3065 * bin/autoheader.in ($version): Likewise.
3066 * bin/autom4te.in ($version): Likewise.
3067 * bin/autoreconf.in ($version): Likewise.
3068 * bin/autoscan.in ($version): Likewise.
3069 * bin/autoupdate.in ($version): Likewise.
3070 * bin/ifnames.in ($version): Likewise.
3072 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3074 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3075 feedback. The most important changes document what happens when
3076 you convert an out-of-range value to a signed integer type, and
3077 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3080 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3081 rewrite, taking notions from the recent discussion on the gcc and
3082 autoconf mailing lists; please see
3083 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3084 and follow the many links.
3085 (Integer Overflow Basics, Signed Overflow Examples):
3086 (Optimization and Wraparound, Signed Overflow Advice):
3087 (Signed Integer Division): New sections.
3089 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3091 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3092 preprocessor macro arguments in traced name.
3093 * doc/autoconf.texi (Defining symbols): Document longstanding
3094 support for AC_DEFINE-ing macros with arguments, and document
3095 behavior when the same variable has multiple AC_DEFINEs.
3096 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3097 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3098 macros directly, giving much shorter and simpler code.
3100 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3102 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3103 space before "$ac_configure_args" to prevent a 'config.status
3104 --recheck' failure if ac_configure_args doesn't contain a leading
3105 space. This works around a problem with the XEmacs configure.ac,
3106 which uses the (undocumented) ac_configure_args variable
3107 inconsistently with Autoconf.
3109 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3111 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3112 Include <limits.h>, and use its INT_MAX to rewrite the
3113 j loop so that it does not overflow 'int'. Problem reported by
3115 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3116 Play it safe by shifting left by 1 rather than multiplying by 2,
3117 as GCC is less likely to optimize this away when the value
3118 is signed (when it assumes overflow leads to undefined behavior).
3119 Also, don't assume time_t uses two's complement.
3121 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3123 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3124 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3125 dumps core on it. Report by Tim Rice.
3127 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3129 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3130 --disable-option-checking to --help output even when
3131 AC_PRESERVE_HELP_ORDER is not used.
3132 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3133 --with argument, rather than argument with [-.] replaced by
3135 * NEWS: Fix typo in previous change; the news was in the
3138 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3140 * NEWS: Warnings are now generated by default for unknown
3141 --enable-* and --with-* options.
3142 * doc/autoconf.texi (Option Checking): Renamed from
3143 (Configure Option Checking). Tighten up the wording a bit.
3144 (External Software, Package Options): Cross-reference to Option
3145 Checking, and use this to shorten our section.
3146 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3147 "$x" to test "x$foo" != x.
3148 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3149 Don't warn if $enable_option_checking is "no".
3150 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3151 ac_unrecognized_opts to the empty string.
3152 Don't echo the unrecognized opts, as this might mishandle
3153 backslashes or leading -.
3154 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3155 usage next to the other --disable-FEATURE options in the
3158 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3160 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3161 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3162 Print warning for unrecognized --with and --enable options
3163 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3164 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3165 Disable option checking when subdirs are configured.
3166 (AC_OUTPUT): If warnings are enabled, print warning about
3167 unrecognized --with and --enable options at the end of
3168 the configure output (as well as at the beginning).
3169 * doc/autoconf.texi (Option Checking): New node.
3170 Document new option warning functionality.
3172 2006-12-16 Eric Blake <ebb9@byu.net>
3174 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3175 * NEWS: Start news for current version.
3177 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3179 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3180 Define HAVE_GETMNTENT to 1, not to the empty string.
3181 Problem originally reported by Jochen Friedrich in
3182 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3184 This change prompted by a problem report by Andrey Simonenko in
3185 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3186 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3187 object-like macros only, in the traditional portable character
3189 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3190 Warn about attempts to define things that are not identifiers.
3191 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3192 awful hack that AC_DEFINEd macro names containing parentheses.
3194 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3196 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3197 too drastic, even if Texinfo in theory requires it for info mode.
3199 (config.status Invocation): Renamed back from Recreating a
3201 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3202 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3204 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3206 * NEWS: Version 2.61a.
3208 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3209 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3211 * NEWS: Document changes with echo and printf, and the lack
3212 of limits on the total size of multi-line values of substituted
3213 variables, and the AC_FUNC_FSEEKO fix.
3215 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3217 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3218 Writing configure.ac.
3219 (Autoconf Input Layout): Renamed from configure.ac Layout.
3220 (Recreating a Configuration): Renamed from config.status Invocation.
3221 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3222 (acconfig Header): Renamed from acconfig.h.
3223 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3224 (Writing Testsuites): Renamed from Writing testsuite.at.
3225 (Autom4te Cache): Renamed from autom4te.cache.
3227 * BUGS: Remove mention of VPATH problem, since it's now documented
3228 not to be a bug in the Autoconf build procedure itself, but rather
3229 a problem with the proprietary `make' programs.
3231 * doc/autoconf.texi (Build Directories): Add a cross reference
3234 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3235 * doc/standards.texi: Sync from gnulib.
3237 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3238 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3239 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3240 generated automatically.
3242 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3244 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3245 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3246 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3248 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3250 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3251 `CEOF$ac_eof' special marker, the awk script cannot contain a
3252 line matching `^CEOF', so this is not needed any more.
3253 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3254 special marker in the test.
3256 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3258 * tests/tools.at (autom4te preselections): Use `find -newer';
3259 remove one of the sleeps.
3261 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3262 more readable, using ...
3263 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3265 * doc/autoconf.texi (autoheader Invocation): Do not double-
3266 quote the parameter of `AH_BOTTOM' in the example.
3268 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3270 * doc/autoconf.texi (Configuration Headers): Remove the
3271 example with multiple input files.
3272 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3273 multiple input files.
3275 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3277 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3278 creating the awk substitution script, handle one input line at a
3279 time, so that the maximum length of a substituted (multi-line)
3280 value is not limited by the size of the sed pattern space.
3281 The trade-off is a slightly repetitive sed script.
3282 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3283 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3284 * tests/torture.at (Substitute a 2000-byte string): Increase the
3285 test with several long lines, they should not be caught by sed
3288 * tests/tools.at (autom4te preselections): New test, to flag
3289 entries missing from autom4te.cfg.
3290 Report by David Byron <dbyron@hheld.com>.
3292 * tests/torture.at (Substitute a 2000-byte string): Actually use
3293 AC_PROG_AWK, so the last change works as intended.
3294 (Substitute and define special characters): Likewise.
3295 (Substitute a newline): Likewise.
3297 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3298 instead of `awk' consistently.
3299 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3300 * tests/torture.at (Torturing config.status): Test both the
3301 result of AC_PROG_AWK and plain awk.
3302 (Substitute a 2000-byte string): Likewise.
3303 (Substitute and define special characters): Likewise.
3304 (Substitute a newline): Likewise.
3306 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3308 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3309 can be assigned to a function pointer. Problem reported by
3310 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3311 part of a patch by Ralf Wildenhues in that same bug report.
3313 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3315 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3316 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3318 2006-12-01 Eric Blake <ebb9@byu.net>
3320 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3321 cross-compiling from cygwin to mingw.
3322 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3323 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3324 to lib/autoconf/c.m4.
3326 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3328 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3329 string for more reliable failure. Wrap the entire test that
3330 causes the broken Solaris printf to dump core, in a subshell,
3331 so the segmentation fault message is reliably suppressed.
3332 Fix shell expansion errors by using /usr/ucb/echo always;
3333 avoid an error on systems without it by another subshell.
3334 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3335 subshell-$as_echo to `as_echo', for better error message.
3337 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3339 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3340 `BASH_SOURCE' contain a newline, set them to empty, as they may
3343 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3345 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3346 years and is too hard to maintain now. The last straw was
3347 reported by Jerker Baeck in
3348 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3349 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3350 * doc/autoconf.texi (Particular Functions): Move
3351 AC_FUNC_SETVBUF_REVERSED from here...
3352 (Obsolete Macros): ... to here. Say that it does nothing now.
3353 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3354 Turn into (almost) a no-op.
3356 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3358 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3359 These macros are obsolescent and new applications shouldn't need them.
3360 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3361 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3362 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3363 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3364 (AC_FUNC_VPRINTF): Likewise.
3365 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3366 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3367 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3369 * doc/autoconf.texi (Setting Output Variables): Mention that
3370 @VAR1@VAR2 has unspecified behavior. Problem reported by
3372 * NEWS: Mention this.
3374 * Makefile.am: Put only a single '#' into the copyright notice,
3375 so that it's also present in the output file. Standardize wording
3376 in makefile copyright notices to match GNU coding standards.
3377 * bin/Makefile.am: Likewise.

3387 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
3390 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3392 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3393 in the sed script that mangles the awk script: delete up to the
3394 first exclamation mark only.
3395 * tests/torture.at (Substitute and define special characters):
3398 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3400 Rewrite config files generation: avoid quadratic growth in
3401 the number of substituted variables by using awk instead of sed
3402 for the bulk of the substitutions.
3403 * NEWS: Mention this.
3404 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3405 forbidden in the output (and thus input) file.
3406 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3407 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3408 generate just one large awk script for substitutions,
3409 eliminating much of the earlier complexity, while adding some
3410 new complexity. Only expand the substitution templates at
3411 configure time, for smaller configure script size. If
3412 _AC_SUBST_FILES are used, test 'awk' for working getline support
3413 at config.status time. If absent, interpolate through the
3414 shell. The awk script was written with much help
3415 from Paolo Bonzini and Paul Eggert.
3416 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3417 (_AC_SED_FRAG_NUM): Likewise.
3418 (_AC_SUBST_CMDS): Renamed from...
3419 (_AC_SED_CMDS): ...this.
3420 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3421 * tests/torture.at (Substitute a 2000-byte string): Also
3422 substitute a line with 1000 words, and a variable with several
3424 (Substitute and define special characters): Test awk special
3425 characters, and put substitution input strings `@foo@' in the
3426 output, to test that no recursion happens; test several other
3427 combinations from Paolo Bonzini.
3429 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3431 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3432 that replaced echo with AS_ECHO where this wasn't necessary.
3433 Problem reportd by Ralf Wildenhues.
3434 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3435 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3436 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3438 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3440 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3442 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3444 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3445 that traditional Awk lacks 3-arg "split". It has it.
3446 Mention that FS must be a single character, and a few other
3447 99-byte limits of traditional Awk.
3448 Mention that if (i in a) doesn't work with traditional Awk.
3450 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3452 * tests/autotest.at (BSx641-newline in command):
3453 (BS-BS-newline in command, BSx640-newline in command):
3454 (Newline-CODE-BS-newline in command):
3455 (Single-quote-BS-newline in command):
3456 (Single-quote-newline-BS-newline in command):
3457 Use printf '%s\n' instead of echo, for portability to hosts
3458 where echo interprets backslashes. This will break on hosts
3459 that lack printf, but for now let's assume all such hosts
3460 are dead (if not, we should get reports of test failures).
3462 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3464 'echo' has some portability problems, when given a first argument
3465 with a leading '-', or when given any argument containing '\'.
3466 Avoid using 'echo' in these cases.
3467 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

3470 * lib/autotest/general.m4 (AT_INIT): Likewise.
3471 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
3472 argument might be unportable.

3487 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
3488 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
3489 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
3490 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
3491 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3492 * bin/autoconf.as: Redo verbose flag implementation, as the old
3493 scheme wouldn't work with AS_ECHO.
3494 * lib/autotest/general.m4 (AT_INIT): Likewise.
3495 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3496 Don't use ECHO_T, since ECHO_N is now reliable.
3497 * lib/autotest/general.m4 (AT_INIT): Likewise.
3498 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3499 rather than using a here-document to put the script into a file.

3503 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3504 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any

3508 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

3510 operand, as AS_ECHO requires. Avoid double file name expansion.
3511 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3512 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3513 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3514 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.

3516 Double-quote strings that would otherwise contain M4 comments.
3517 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3519 * configure.ac (AC_INIT): Bump to 2.61a.
3522 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3526 * configure.ac (AC_INIT): Bump to 2.61.
3529 * tests/autotest.at (Macro with backslash in a test title):
3530 Comment out for now, as this tests neither fails nor passes
3531 reliably. Problem reported by Ralf Wildenhues.
3533 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3535 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

3614 and Joel E. Denny <jdenny@ces.clemson.edu>
3615 and Paul Eggert <eggert@cs.ucla.edu>
3617 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
3618 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
3621 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3623 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
3624 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
3625 Imported from a similar patch to gnulib by Bruno Haible.
3627 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3629 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

3646 and Stepan Kasal <kasal@ucw.cz>
3648 Handle special characters in test case titles correctly.

3651 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.

3656 Single-quote in a test title,
3657 Double-quote in a test title): Don't expect failure anymore.
3658 (Backslash in a test title): Put a non-whitespace character after the
3659 backslash so that Bourne shells might actually see it as an escape
3661 (Brackets in a test title,
3662 Pound in a test title,
3663 Comma in a test title,
3664 Quoted Macro in a test title,
3665 Macro in a test title,

3667 (Macro with backquote in a test title,
3668 Macro with double-quote in a test title,
3669 Macro with backslash in a test title): New tests expected to fail.
3670 * tests/torture.at (#define header templates): M4-quote this title in
3671 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3672 The visible effect was a stray [] in the testsuite output.
3674 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3676 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3677 `trap ... 0' inside a function, for AIX sh.
3679 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3681 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3682 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3683 5363) simply issues a warning when dividing by zero at compile
3684 time. Problem reported by Elias Pipping.
3686 2006-10-26 Eric Blake <ebb9@byu.net>
3689 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3690 show effect on macros that expand with commas.

3713 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
3715 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
3717 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3718 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3719 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3720 reported by Nelson H. F. Beebe for Coreutils 6.4.
3722 * tests/tools.at (autoconf --trace: user macros): Remove test
3723 for tracing multiline macros, since m4 1.4.7a uses a different
3724 way to number lines. Problem reported by Ralf Wildenhues.
3726 2006-10-24 Stepan Kasal <kasal@ucw.cz>
3728 * bin/autom4te.in (handle_m4): Do not redirect stdin to
3729 /dev/null since the heuristics for interactive behaviour was

3750 * NEWS: Remove AC_CACHE_CHECK_INT.
3751 * doc/autoconf.texi (Caching Results): Likewise.
3752 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
3753 AC_CACHE_CHECK_INT, since it's no longer public.
3754 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
3755 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

3783 2006-10-14 Stepan Kasal <kasal@ucw.cz>
3785 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
3786 looking for special shell characters.
3787 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
3788 macro defined by AS_VAR_PUSHDEF before passing it as a

3800 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
3802 (Imported from Automake.)
3803 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3804 which incorrectly sets the mode of an existing destination
3805 directory. In some cases the unpatched install-sh could do the
3806 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3807 system. We hope this is rare in practice, but it's clearly worth
3808 fixing. Problem reported by Alex Unleashed in
3809 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3810 Also, don't bother to check for -m bugs unless we're using -m;
3811 suggested by Stepan Kasal.
3813 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
3815 Import this change from Automake:
3817 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
3818 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
3819 is enabled by default with gnu and gnits strictness.
3820 Report from Bruno Haible.
3822 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
3823 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
3824 gnu and gnits modes.
3826 Import this change from Config:
3828 2006-09-20 Ben Elliston <bje@gnu.org>

3831 Import this change from Gnulib:
3833 2006-09-16 Karl Berry <karl@gnu.org>
3834 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
3835 to avoid sectioning errors.
3837 Import these changes from Texinfo:
3839 2006-10-04 Karl Berry <karl@gnu.org>
3840 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
3841 (\quoteexpand): rename to \rquoteexpand.
3842 (\codequoteleft): new def, to look for @set codequotebacktick.
3843 (\lquoteexpand, \quoteexpand): new defs.
3844 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
3845 (\code): must use new \...Char values, since now ` is active.
3847 2006-08-26 Karl Berry <karl@gnu.org>
3848 * build-aux/texinfo.tex (\textdegree): New command.
3850 2006-08-12 Karl Berry <karl@gnu.org>

3855 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
3857 2006-10-13 Stepan Kasal <kasal@ucw.cz>
3859 * doc/autoconf.texi (Autoheader Macros): Warn that the text
3860 added to the template can get mangled.
3862 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3864 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
3865 include the default headers, and redefine obstack_chunk_alloc
3866 and obstack_chunk_free. Fixes false failure with glibc.
3868 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
3870 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
3871 for backward compatibility with Libtool 1.5.22. Problem reported
3874 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3876 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require

3882 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
3883 the NonStop platform.
3884 * doc/autoconf.texi (Posix Variants): Likewise.
3885 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
3887 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
3888 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
3889 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
3890 Use a better substitute, by inspecting the output of "ls"
3891 rather than just using ":".
3892 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
3893 rather than AS_EXECUTABLE_P, since we needn't worry about
3894 non-regular files here.
3896 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
3897 due to configuration hassles with this. See Tonya Underwood's report
3898 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
3899 * doc/autoconf.texi (Special Shell Variables): Likewise.
3901 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
3902 Stepan Kasal <kasal@ucw.cz>
3904 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
3905 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
3907 2006-10-11 Stepan Kasal <kasal@ucw.cz>
3909 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
3910 initialization which is not inherited through the environment
3911 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
3912 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
3914 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>

3917 problems with mkdir -p -m.
3919 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
3921 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
3922 comment about ac_cpp_err; it was incorrect, and anyway
3923 ac_cpp_err is being removed below.
3924 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
3925 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
3926 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
3928 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
3929 with werror_flag and conftest.err and so forth. This is more
3930 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
3931 and anyway the user shouldn't normally want to see this gorp logged.
3932 Problem reported by Ralf Wildenhues.
3933 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
3934 empty, not 'no', since the rest of the code uses 'test -z'.
3936 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
3938 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3939 Use a single call to AC_DO_TOKENS rather than multiple, for
3941 (_AC_LINK_IFELSE): Test that resulting file is executable.
3942 Problem reported by mwoehlke in
3943 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
3945 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
3946 than creating a file to use with test -x; this is much faster.
3948 2006-10-02 Bruno Haible <bruno@clisp.org>
3950 * lib/autom4te.in (Automake-preselections): Add
3951 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
3953 2006-09-27 Stepan Kasal <kasal@ucw.cz>
3955 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
3956 standard error, `experr' should be used, not `expout'.
3958 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>

4412 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
4414 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
4415 after -R regardless of host. Patrick Welche reports that this
4416 fixes things on NetBSD 3.99.
4418 * NEWS: Recommend M4 1.4.5.
4420 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
4421 * tests/tools.at (autom4te cache): Update wording of diagnostic
4424 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4426 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
4427 under AC_C_VOLATILE.
4428 (Volatile Objects): Be a little less skeptical about what
4429 "volatile" means. Derived from thoughts by Ben Pfaff in
4430 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
4432 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4434 * doc/autoconf.texi: Fix some typos.
4436 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4438 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4439 more globally, since the 2006-06-30 patch didn't suffice. Problem
4440 reported by Keith Marshall. Also, don't bother with builddir2,
4441 since it shouldn't be needed any more.
4443 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
4445 * doc/autoconf.texi (Generic compiler characteristics):
4446 Document AC_COMPUTE_INT. Fix wrong statements on Default
4447 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
4449 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
4450 (_AC_COMPUTE_INT): Add obsoletion warnings.
4451 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
4454 * NEWS: Document change.
4456 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
4458 * doc/autoconf.texi (Volatile Objects): New section.
4460 * NEWS: Document previous change.
4462 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4464 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4465 Require that long long int be at least 64 bits wide. C99 requires
4466 this and enough programs depend on it so we should check for it.
4467 Bruno Haible reports in
4468 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4469 that long long int is 32 bits wide with some nonstandard compilers.
4470 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
4472 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4474 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4475 to a nonexistent file, so that we don't have to worry about
4476 a local site configuration that doesn't use /usr/local.
4477 Problem reported by Keith Marshall in
4478 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4480 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4482 * doc/autoconf.texi: Be more consistent about using @acronym with
4483 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4484 quite right (it talked about "OSF/Tru64", even though the
4485 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4486 and it even mentioned "OSF 4"!) and at this point there's little
4487 reason to talk about OSF any more, since it died in 1994.
4488 (Specific Compiler Characteristics): Simplify example of
4489 negative-size array.
4490 (File Descriptors): Reorder to make the text flow better.
4491 Remove joke about "appreciate the various levels"; I didn't get it.
4492 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4493 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4494 (File Descriptors, Limitations of Usual Tools):
4495 Tone down the advice against renaming or removing open files.
4496 (Limitations of Usual Tools): Add a new section, on 'rm'.
4498 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4500 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4501 -lXt in LIBS, idea from Karsten Hopp; this was due since
4504 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4505 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4506 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4507 (which belong to Xt, not X itself). See Debian bug 327655.
4509 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4511 * configure.ac (AC_INIT): Bump to 2.60a.
4514 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4518 * configure.ac, NEWS: Update.
4520 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4522 * config/texinfo.tex: Sync from upstream.
4524 * bin/autom4te.in (handle_traces): Transform the `@S|@'
4525 quadrigraph correctly in traces.
4527 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
4530 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
4531 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4533 * doc/autoconf.texi (Changed Directory Variables): New node,
4534 to document the whole `datarootdir' business a bit better.
4536 * tests/torture.at (datarootdir workaround): Extend test.
4537 Prompted by report by Alexandre Julliard.
4539 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4541 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4542 when using default mode of IBM C 6 for AIX. Problem and two-line
4543 fix reported by Larry Jones.
4545 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4547 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4548 about literal '${datarootdir}' if a definition is found in the
4551 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4553 * NEWS: Use "M4" rather than "m4" when appropriate.
4554 Problem reported by Eric Blake.
4555 * doc/autoconf.texi: Likewise.
4556 Use @acronym around BSD, GCC, and GNU when appropriate.
4557 (Why GNU M4): Renamed from "Why GNU m4".
4558 (Redefined M4 Macros): Mention that Posix
4559 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4560 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4563 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4565 * bin/autom4te.in (handle_output): Do not forbid the empty
4567 * tests/tools.at (autoconf: the empty token): New test.
4569 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4571 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4572 calls, so that we do not care whether they are LIFO or FIFO;
4573 in the m4_wrap, do not check which diversion is the topmost
4574 one, just check that the stack is balanced at the end.
4575 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4576 base diversion forever--pop the previous diversion before
4577 opening the new one; consequently, remove the m4_wrap call.
4578 * lib/autotest/general.m4 (AT_INIT): Likewise.
4579 * tests/m4sugar.at: Do not use
4580 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
4582 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4583 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4585 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4586 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4587 Rework example of m4wrap token-pasting trouble so that it doesn't
4588 care whether it's LIFO or FIFO.
4589 Fix some "contrary to"s that are awkward in English.
4591 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4593 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4594 to `yes' instead of `int$1_t' if the type is found, for more
4595 consistent configure output (where $1 is the number of bits).
4596 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4597 Suggested by Bruno Haible.
4599 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4600 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4601 with system headers. Report by Bruno Haible.
4603 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4605 * config/config.guess, config/config.sub: Sync from upstream.
4607 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4608 in order to avoid picking up an older installed frozen m4sh.m4f.
4609 Besides an outdated shell startup, this could have been created
4610 by an earlier M4 version with incompatible frozen file format.
4612 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4614 * README: Recommend m4 1.4.4 instead of 1.4.3..
4615 * doc/autoconf.texi: Likewise.
4616 (Special Chars in Names): Say that $(.FOO) is portable, as
4617 suggested by Stepan Kasal.
4618 (Installation Directory Variables, Build Directories):
4619 (Automatic Remaking, Subdirectories, Fortran Compiler):
4620 (Making testsuite Scripts, Defining Directories):
4621 Quote variable usages better.
4622 (Making testsuite Scripts): Add clean-local rule to makefile
4623 snippet, by Eric Blake.
4624 (Installation Directory Variables): Fix table item font.
4625 Reword slightly to clarify. Generalize advice about
4626 not using special characters to include all file-related
4627 vars, not just VPATH.
4628 (Special Chars in Variables): Warn about special characters in
4630 (Assignments): Clarify default-value example as suggested by
4632 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4633 (Special Shell Variables): Note leading ./ or ../, as suggested
4635 (Limitations of Builtins): Under cd, warn about CDPATH.
4636 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4639 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4641 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4642 `@var', for texi2html.
4643 (Systemology): Some more word wrapping, for DVI output.
4644 (autom4te Invocation): The short option for `--melt' is `-M',
4647 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4649 * doc/autoconf.texi: More formatting and English tweaks,
4650 many suggested by Ralf Wildenhues.
4651 Reword to avoid "@code{...}'s" and the like, since it's ugly
4652 with Emacs info mode. discontents -> woes.
4653 Put a few "will"s back. time stamp -> timestamp.
4654 side-effect -> side effect.
4656 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4658 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4659 Warn about $@ not persisting. Problem reported by Julien Danjou in
4660 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4661 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4662 Mention other special chars, too.
4664 2006-06-14 Eric Blake <ebb9@byu.net>
4666 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4668 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4670 * doc/autoconf.texi: Some systematic minor improvements, as
4671 follows. Use "makefile" when talking about makefiles
4672 generally (which might be named "makefile" or "Makefile" or even
4673 "foo.mk"), "Makefile" when talking about a specific makefile
4674 called "Makefile". This unclutters the text from weird quotes
4675 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4676 values" rather than "@var{foo}s" and similar constructs containing
4677 "}s". Use "Make rules" rather than "Makefile rules". Minor
4678 English-language improvements. Change the prefix "sub-" to "sub"
4680 Put blank lines around examples more consistently.
4681 Avoid "rather" and "very" as intensifiers.
4682 Avoid "will" as an auxiliary.
4683 (Limitations of Make): Split this node into....
4684 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4685 (Leading _ in Macro Names, Backslash-Newline-Newline):
4686 (Backslash-Newline Comments, Long Lines in Makefiles):
4687 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4688 (obj/ and Make, make -k Status, VPATH and Make):
4689 (VPATH and Double-colon, $< in Explicit Rules):
4690 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4691 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4692 New nodes, resulting from splitup of Limitations of Make.
4693 All cross-references changed. Raise the top node from
4694 a section to a chapter, and all subnodes accordingly.
4695 Redo the introductory wording to match the new organization.
4696 (Installation Directory Variables): Use an example that is
4697 closer to what Autoconf actually does. Mention that VPATH's
4698 value should not contain metacharacters or white space.
4699 (Fortran Compiler): Fix a VPATH bug in an example.
4700 (Leading _ in Macro Names): Mention that this problem is no longer
4701 of practical concern.
4702 (VPATH and Make): Reword the advice to make it clearer
4703 that Autoconf and Automake support VPATH in non-GNU make, but
4704 many packages have bugs in this area.
4705 ($< in Explicit Rules): Refer to Build Directories rather
4706 than using a (non-VPATH-safe) example.
4707 (Automatic Rule Rewriting): Mention the sort of disaster that
4708 can ensue with Solaris-style rule rewriting with VPATH.
4710 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4712 * doc/install.texi (Compilers and Options): Weaken the
4713 suggestion to use GNU make for VPATH builds.
4715 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4716 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4718 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4719 in regular expression.
4721 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4723 * doc/autoconf.texi (Installation Directory Variables):
4724 Drop extra @samp from `@table @samp' item.
4725 (Limitations of Usual Tools): Comment fix.
4726 Do not nest @samp just to point to other table items.
4727 (Writing testsuite.at) <AT_CHECK>: The second argument to
4728 `@dvar' is already @samp'ed.
4729 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4730 do not use @var in the second argument.
4732 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4734 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4735 $as_shell.exe too. Problem reported by Andreas Buening in
4736 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4738 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4740 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4741 `unused variable' compiler warning, for `-Wall -Werror'.
4742 Reported by Jaap Haitsma in
4743 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4745 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4747 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4748 case the compiler dumps core. Problem reported for
4749 OpenServer 5.0.7 by Tim Rice in
4750 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
4751 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4754 2006-06-06 Tim Rice <tim@multitalents.net>.
4756 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4757 "ERROR" only shows up in "make check" output if there is an
4760 2006-06-06 Eric Blake <ebb9@byu.net>
4762 * tests/tools.at (automatically allowed tokens): Fix typo.
4764 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4766 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
4768 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
4769 typically overflows on x86 CPUs, even though the C standard
4772 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4774 * configure.ac (AC_INIT): Bump to 2.59e.
4777 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4781 * config/texinfo.tex: Sync from upstream.
4783 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4784 seen, invoke libtoolize with `--ltdl' argument.
4785 * lib/autom4te.in (Autoreconf-preselections): Adjust.
4787 Suggested by Eric Blake.
4789 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4791 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
4792 reported by Ralf Wildenhues.

4806 message issued by AC_REQUIRE.
4807 * tests/m4sugar.at: Check m4_require's error message.
4808 * tests/base.at: Check AC_REQUIRE's error message.
4809 * tests/local.at (AT_CHECK_M4): New macro, almost identical
4811 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
4813 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
4814 `expout' as the last parameter.
4815 * tests/tools.at: Adapt to the above change.
4817 2006-06-04 Stepan Kasal <kasal@ucw.cz>
4819 * doc/autoconf.texi (Limitations of Usual Tools): Correct
4820 information about race-free implementations of mkdir.
4822 2006-06-04 Eric Blake <ebb9@byu.net>
4824 * bin/autoreconf.in (help): Document M4 environment variable.

4829 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
4831 * NEWS: GNU make now recommended for VPATH builds.
4832 Mention that some macros are now documented to be obsolescent.
4833 * doc/autoconf.texi:
4834 Prefer "current" to "modern" to describe
4835 currently-used (albeit perhaps old-fashioned) hosts.
4836 Mention which ancient features no longer need to be worried about.
4837 setgid -> set-group-ID
4838 setuid -> set-user-ID (these are the Posix terms)
4839 Fix some misuses of "only".
4840 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
4841 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):

4849 Mention that these macros are obsolescent.
4850 (Installation Directory Variables): shall -> should
4851 (File Descriptors): Mention that 0, 1, 2 might get reopened.
4852 Mention that it's now safe to use 3 and 4.
4853 (Limitations of Usual Tools): cp -r is now specified by Posix.
4854 Omit longwinded and obsolescent discussion of cp -f.
4855 Modernize discussion of expr, ls.
4856 (Limitations of Make): Modernize discussion of VPATH builds.
4857 Mention $? as a workaround in some cases.
4858 * doc/install.texi (Basic Installation):
4859 Mention "./configure; make; make install" first. Be more
4860 specific about why this file is generic. Remove unnecessary
4861 parens. Remove misleading "only". Remove obsolete advice
4862 about csh. Don't say "configure" takes awhile; say it
4863 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
4864 and CC=c99 rather than CC=c89, as these are blessed by current
4865 Posix. Recommend GNU make if doing a VPATH build.
4867 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
4869 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
4870 examples involving shell prompts.

4888 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
4890 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
4891 about quoting the case statement, just in case.
4892 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
4893 was fixed in ksh93g; reported by Ralf Wildenhues.
4895 2006-05-31 Stepan Kasal <kasal@ucw.cz>
4897 * doc/autoconf.texi (System Services): Do not document
4898 overriding EXEEXT via ac_cv_exeext=ext.
4899 (Particular Programs) <AC_PROG_MKDIR_P>:
4900 Document that ${MKDIR_P} understands --.
4901 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
4904 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4906 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
4907 argument with leading hyphen. Problem reported by Paul Eggert.
4909 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4911 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
4912 about quoting ac_try: quote all of it, if any of it seems suspicious.
4913 This means we don't have to worry about ${ or sed any more.
4914 Also, double-quote the case statement, to work around misuses via
4915 underquoting as reported by Ralf Wildenhues in
4916 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
4917 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
4918 undocumented and dangerous macro.
4919 Problem reported by Ralf Wildenhues in
4920 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
4922 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4924 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
4925 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
4926 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
4928 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4930 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
4931 since evidently some packages rely on the old, broken behavior.
4932 Problem reported by Ralf Wildenhues in
4933 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
4934 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
4935 pre-2006-05-26 definitions, but leave in the comments that
4936 these macros are dangerous and should not be used.
4937 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
4938 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
4939 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
4940 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
4941 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
4943 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4945 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
4946 the use of 'tr', since this is our only use of 'tr'.
4948 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4949 and Paul Eggert <eggert@cs.ucla.edu>
4951 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
4952 Don't assume 'grep' works on long lines, since AIX grep doesn't.
4954 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4956 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
4957 the output file in the `${datarootdir}' test.
4959 2005-05-28 Stepan Kasal <kasal@ucw.cz>
4960 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4962 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
4963 mention of `datarootdir' in the input file(s), but literal
4964 `${datarootdir}' in the output file, and we haven't warned yet,
4965 then warn as well: the user may have (erroneously) used
4966 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
4967 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
4968 * tests/torture.at (datarootdir workaround): Extend this test.
4971 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4972 and Paul Eggert <eggert@cs.ucla.edu>
4974 * doc/autoconf.texi (autoheader Invocation): The first argument to
4975 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
4976 alternatives and clear up the language a bit.
4978 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
4980 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
4981 ac_config_guess, ac_config_sub, ac_configure.
4982 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4983 Fix typo that prevented an unnecessary space from being removed.
4984 Problems reported by Ralf Wildenhues in:
4985 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
4987 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4989 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
4990 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
4991 Don't use the term "thread-safe" to talk about mkdir race
4992 conditions, since the problem is more a process than a thread
4993 issue. Problem reported by Stepan Kasal in:
4994 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
4995 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
4996 the test for 'install' more closely. Look at MKDIR_P first.
4997 Look in the PATH, and at /opt/sfw/bin.
4998 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
4999 Don't bother to try mkdir -p, since we already check mkdir --version;
5000 just look at the version number. (There's no easy way to check
5001 for race-free implementations.)
5002 * tests/tools.at (autoconf: subdirectories): Adjust to above
5003 changes, since MKDIR_P now might end in "/mkdir -p".
5005 * doc/autoconf.texi (autoheader Invocation): Mention that the
5006 first arg of AC_DEFINE_UNQUOTED must be a literal.
5007 Problem reported by Ben Pfaff in
5008 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5010 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5011 * doc/autoconf.texi (Special Chars in Variables): New section.
5012 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5013 (Installation Directory Variables): Quote $(datadir) better.
5014 (Limitations of Builtins): Describe some of eval's trickiness.
5016 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5017 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5018 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5019 in front of every arg, not just trailing args. Quote apostrophes.
5020 (_AC_EVAL_ECHO): New macro.
5021 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5022 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5024 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5025 exposed by quoting of eval argument. Put the command on line line
5027 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5028 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5029 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5030 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5031 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5032 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5033 Use eval more safely.
5034 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5035 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5037 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5038 lines, exposed by quoting of eval argument.
5040 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5041 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5043 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5044 initialization of `ac_cv_exeext', do not override it if it was
5045 already set, unless it was set to `no', for compatibility with
5046 Autoconf-2.13, and comment this.
5047 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5048 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5049 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5050 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5051 Document that this test may be overridden by setting
5054 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5056 Revert these two patches:
5058 2006-04-06 Eric Blake <ebb9@byu.net>
5059 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5060 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5063 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5064 Clean up _AC_COMPILER_EXEEXT* macros.
5065 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5066 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5067 ac_file to the name of the default output file and call
5068 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5069 initial `rm' of the candidate files...
5070 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5071 the same list in subsequent `rm' calls, and for the temporary
5072 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5073 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5074 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5075 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5076 no longer needed) by libtool. Make it a cache check.
5077 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5078 copied here by mistake.
5079 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5080 _AC_COMPILER_EXEEXT.
5081 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5082 _AC_COMPILER_OBJEXT directly.
5083 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5085 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5087 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5088 Fix description of how the buggy `sed' works.
5090 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5094 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5095 ENOLCK. Only mention `make -j' when applicable. Only raise
5096 fatal errors when `make -j' is involved. Improve error message.
5098 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5100 * doc/autoconf.texi (Here-Documents): We now know more about
5101 the variable expansion in here documents bug.
5102 Thanks to Tim Rice and Stepan Kasal.
5104 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5105 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5107 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5109 * tests/autotest.at (Multiline command from M4 expansion):
5110 No failure to be expected if the shell quotes newlines in
5111 commands in the `set -x' output. Report by Tim Rice.
5114 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5116 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5117 expansion in the here-documents used by config.status, as that
5118 runs afoul of the Korn shell version M-12/28/93d bug described in
5119 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5120 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5121 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5123 2006-05-23 Jim Meyering <jim@meyering.net>
5125 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5126 Fix typo introduced with 2006-04-02 change. It reversed the sense
5129 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5131 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5132 ac_dB slightly, to save bytes in the script.
5133 Max out at 50 lines, rather than 96; this is more likely
5134 (though not guaranteed) to avoid obscure 'sed' failures.
5136 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5138 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5139 `tr -d -' as bad option argument. Work around this by deleting
5140 an unrelated character.
5141 Report by Tim Rice <tim@multitalents.net>.
5143 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5144 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5145 Stepan Kasal <kasal@ucw.cz>
5147 * doc/autoconf.texi (Particular Programs): Do not promise that
5148 we always prefer the GNU version of the program, and that we
5149 search according to PATH; both rules can have exceptions.
5150 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5151 AC_PROG_SED. Move descriptions of limitations
5152 to the Limitations of Usual Tools section.
5153 (Limitations of Usual Tools) <sed>: Mention script length
5154 limitations with Solaris /usr/ucb/sed.
5155 <grep>: Fix wording for empty alternative. Mention that -c and
5156 -l should not be combined, and that -E and -F should not be
5159 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5160 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5162 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5163 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5165 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5167 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5168 AC_DEFINE is now passed to m4_pattern_allow.
5169 * NEWS: Mention that; likewise for AC_SUBST.
5170 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5171 the parameter to m4_pattern_allow.
5172 * tests/tools.at: Add a check for that.
5174 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5176 * lib/autoconf/status.m4: Fix typos.
5178 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5180 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5181 only the files that this macro generates.
5183 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5185 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5186 the HP-UX sed limitation of 99 commands, labels do not count.
5187 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5189 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5191 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5193 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5194 Import the following fix from coreutils:
5196 2006-01-13 Jim Meyering <jim@meyering.net>
5198 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5199 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5200 not double-quote uses of that variable, to accommodate the rare
5201 case in which getmntent is available in none of the libraries
5202 checked. This happens at least on FreeBSD 5.0.
5204 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5206 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5207 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5208 some other programs unwisely rely on these undocumented vars.
5209 But put in warning comments about them.
5210 Problem reported by Ralf Wildenhues in
5211 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5212 * NEWS: Document that these variables are intended to go away.
5214 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5216 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5217 and set the language to C++ (analogous to the equivalent Fortran
5220 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5221 * doc/autoconf.texi (C++ Compiler): Document it.
5222 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5225 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5227 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5228 that caused config.status to generate 100-command sed scripts; the
5229 portable limit is 99.
5231 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5233 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5234 variable `ac_d' instead of `d' to avoid infringing namespace.
5235 Report by Ralf Menzel.
5237 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5239 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5240 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5241 * tests/tools.at (autoconf: subdirectories): New test, taken from
5242 the corresponding problem report by Ralf Wildenhues in:
5243 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5245 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5246 Quote some uses of shell variables if they might suffer unexpected
5247 globbing. This doesn't fix all instances of quoting problems that
5248 I found, just the easy ones that look safe.
5249 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5250 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5251 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5252 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5253 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5254 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5255 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5257 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5258 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5260 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5262 * bin/autoreconf.in ($help): Reword according to the manual.
5263 Suggested by Olly Betts.
5265 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5266 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5268 * bin/autoreconf.in: Pass the directory argument to
5269 `require_configure_ac'. Fix comment.
5270 * tests/torture.at (Configuring subdirectories): Expose this.
5271 Reported by Olly Betts.
5273 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5275 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5276 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5277 Automake as follows:
5279 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5280 `$configure_in' instead of `configure.in', to preserve
5281 directory component.
5283 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5285 * config/config.guess, config/config.sub, config/texinfo.tex,
5286 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5288 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5290 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5291 test for C99 conformance; (bool) 0.5 is an integer constant
5292 expression, but (bool) -0.5 is not. Problem reported by Fedor
5293 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5295 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5297 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5298 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5299 Warn about obsolete install-sh files. Remove stray sentence
5300 fragment and fix cross reference.
5301 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5302 install -d; this undoes the 2006-05-10 change.
5303 (MKDIR_P): Mark with AN_MAKEVAR.
5304 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5305 that we don't require $INSTALL to be thread-safe. Move comments
5306 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5307 of AC_PROG_INSTALL. Output a message saying that we're checking
5308 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5309 MKDIR_P instead of AC_SUBST.
5310 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5311 Special magic for MKDIR_P, too.
5312 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5314 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5316 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5318 Sync from Automake, as follows:
5320 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5321 * config/install-sh: Initialize IFS, so field splitting isn't
5323 * config/mkinstalldirs: Likewise.
5324 * config/missing: Remove superfluous quotes. Replace all uses of
5325 `[' by `test', for consistency, and for..
5326 * config/missing (sed_minuso, sed_output): New variables.
5327 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5328 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5329 Fixes `missing' to detect `--output' for help2man. Fixes
5330 PR automake/483. Report by Dennis J. Linse.
5331 (autom4te): Document in `missing --help'.
5333 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5335 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5336 * config/install-sh: Don't use 'path' to talk about file names,
5337 as per GNU coding standards. Close a race condition reported by Ralf
5338 Wildenhues and Stepan Kasal. There is still a race condition
5339 on hosts that predate Posix 1003.1-1992, but we can't help this.
5340 Don't mishandle weird characters like space on pre-Posix hosts.
5341 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5342 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5343 AC_PROG_MKDIR_P from AS_MKDIR_P.
5344 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5345 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5346 earlier editions are not (including Automake 1.8.3).
5347 Do not suggest mkinstalldirs for thread-safety.
5348 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5349 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5350 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5351 presence of special characters and race conditions.
5352 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5353 in Autoconf's name space.
5355 2006-05-10 Bruno Haible <bruno@clisp.org>
5356 and Paul Eggert <eggert@cs.ucla.edu>
5358 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5359 from Automake with minor changes.
5360 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5362 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5364 * config/install-sh: Update to Automake CVS version, as follows:
5365 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5366 * lib/install-sh: Simplify the expr implementation of dirname.
5367 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5368 * lib/install-sh: Handle --, and diagnose unknown options.
5370 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5372 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5373 `./autom4te' to create `./testsuite', since the `all' target
5374 will ensure its presence, but `installcheck' should not create
5375 the uninstalled wrappers.
5377 * tests/torture.at (Unusual Automake input files): Skip if we
5378 detect automake < 1.8.
5380 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5382 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5383 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5384 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5387 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5389 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5390 munge (multiple) white space and other oddities.
5391 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5392 single quotes in variable assignment.
5393 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5394 and similar failures by adding multiple spaces, tabs, and other
5396 Report and different test suggested by Francesco Romani
5397 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5399 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5400 single quotes, we only need to search for single quotes; this
5401 both simplifies the search pattern, and makes us less
5402 susceptible to `echo' variations for arguments not containing
5404 (_AC_ARG_VAR_VALIDATE): Likewise.
5406 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5408 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5409 `$*' and IFS concatenation issue with traditional shells and
5410 bash-2.04. Report by Seanster@Seanster.com.
5412 2006-05-03 Bruno Haible <bruno@clisp.org>
5414 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5415 precisely which Mac OS X versions have the od problem.
5417 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5419 * doc/autoconf.texi: Use @option systematically.
5421 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5422 and Bruno Haible <bruno@clisp.org>
5424 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5426 (Integer Overflow): Mention the special case of integer division
5429 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5431 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5432 traditional shells like the Solaris one that do not use the
5433 first IFS character for assembling `$*'.
5434 Prompted by a related report from autoconf_bug@nro.ca.
5436 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5437 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5439 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5440 Mention more problems with the -e option.
5442 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5445 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5447 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5448 in URLs to improve DVI formatted output (requires texinfo 4.6).
5449 (System Services, Systemology, Shellology): Likewise.
5450 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5453 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5455 (Runtime): Fix macro argument names to match description:
5456 `action-if-found' -> `action-if-true' and similarly.
5457 (Obsolete Macros): Likewise.
5458 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5459 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5460 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5462 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5464 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5467 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5470 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5472 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
5473 /bin/sh set unsorted output.

5479 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
5480 (Integer Overflow, Null Pointers, Buffer Overruns):
5481 (Floating Point Portability, Exiting Portably): New sections.
5482 (Writing Test Programs): Fix some langauge. Recommend exiting
5483 with status 1, not merely nonzero. Clarify exit declaration.
5484 (Run Time): Move C exit status stuff to new Exiting Portably section.
5485 (Systemology): Mention Posix and levenez. Update v7 reference.
5486 (Portable Shell): Mention the Posix shell.
5488 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5490 * bin/autoconf.as (me): Replace by as_me.
5492 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5494 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5495 since as_me isn't set yet.
5497 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5499 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5500 a few minor bugs in this area.
5502 * doc/autoconf.texi (Programming in M4sh): Comment out the
5503 documentation of AS_BASENAME, for now.
5504 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5505 (Limitations of Builtins) <basename>: Do not refer to
5507 * bin/autoconf.as (me): Don't use AS_BASENAME.
5508 (dir): Remove the unused variable.
5509 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5510 AS_DETECT_REQUIRED. All uses changed.
5511 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
5513 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
5514 (AS_BASENAME): Use "basename --" to protect against leading "-".
5515 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
5516 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
5517 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
5518 (_AS_DIRNAME_PREPARE): Likewise.
5519 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
5520 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5521 (AS_DIRNAME): Use "dirname --".
5523 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5525 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5526 of "run time" and "run-time" changed to "runtime", for consistency.
5527 * lib/autoconf/fortran.m4: Likewise (in comment).
5528 * lib/autoconf/functions.m4: Likewise.
5529 * lib/autoconf/general.m4: Likewise.
5530 * lib/autoconf/headers.m4: Likewise.
5532 * doc/autoconf.texi (Run Time): Document the exit status situation
5533 with more accuracy and detail.
5535 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5537 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5538 Archive is not officially `GNU' any more. Update URL.
5539 (Defining Directories): Likewise
5540 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5542 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5544 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5545 newline from the `trap' code to finish `config.log'; the NetBSD
5546 /bin/sh resets the exit status after an empty command, as
5547 documented in doc/autoconf.texi.
5548 Reported by Dalibor Topic <robilad@kaffe.org>.
5550 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5552 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5553 Suggested by Bruno Haible.
5555 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5557 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5558 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5559 Instead, just list the shells that we know work.
5560 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5561 changed. Be more cautious about the _cv_ variable.
5562 * tests/tools.at (Syntax of the shell scripts): Check the
5563 _cv_ variable once, at first, to avoid an internal autoconf error
5564 when sh -n does not work.
5566 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5568 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5570 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5572 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5573 use ">&-" since we're only 99.999% sure that this is portable,
5574 and since the MinGW bug is fixed in a different way.
5575 * lib/autotest/general.m4 (AT_INIT): Likewise.
5577 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5579 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5580 before opening config.log, to avoid hitting a bug on MinGW.
5582 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5584 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5585 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5586 This works around a MinGW bug reported by Eric Paire.
5587 Make sure that all writes to the log file append to it,
5588 rather than possibly losing data.
5589 * lib/autotest/general.m4 (AT_INIT): Likewise.
5591 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5593 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5596 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5600 * configure.ac (AC_INIT): Bump to 2.59d.
5602 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5606 * Makefile.maint (news-date-check): Do not require a leading `*'
5607 before the release date in NEWS.
5609 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5610 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5612 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5613 the instantiated file do not contain the string 'datarootdir'
5614 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5615 @mandir@, replace the reference '${datarootdir}' by the value.
5616 * tests/torture.at (datarootdir workaround): New test.
5617 * NEWS: Advertise this temporary fixup.
5618 Based on a patch by Bruno Haible, reported and analyzed by
5619 Paul Eggert and Noah Misch.
5621 2006-04-12 Eric Blake <ebb9@byu.net>
5623 * tests/autotest.at (Debugging a failed test): Fix comment.
5625 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5627 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5628 all the changes since 2006-04-07.
5630 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5632 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5633 succeeded, but `ln -s file dir' failed, take care to remove the
5634 leftover target before the next test, to prevent its spurious
5635 failure; also make sure `ln file dir' works before selecting it.
5636 Thanks to Keith Marshall for pointing this out.
5639 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5640 assignments in `at_debug_args', so that we put them correctly
5641 in the `run' script.
5642 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5643 Reported by Eric Blake.
5645 2006-04-11 Eric Blake <ebb9@byu.net>
5647 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5648 top-level tests after micro-suite has been run. Used in...
5649 (Debugging a successful test, Debugging script and environment),
5650 (Debugging a failed test): ...these new tests. The first of these
5652 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5653 macro, split out from...
5654 (AT_INIT): ...here, so that using -d also generates a run script.
5655 Document that -d inhibits top-level logging.
5656 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5657 inhibits top-level logging; debug scripts are created.
5659 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5661 * tests/autotest.at (Empty test, Empty check): New test to check it.
5663 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5666 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5668 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5669 the files if a problem appears. Make the empty *.at files
5670 read-only, too. Proposed by Ralf Wildenhues.
5672 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5674 * config/Makefile.am: Add comment to force updated Makefile.in.
5676 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5677 space only patch to this file, this patch causes the Makefile.in
5678 files that include freeze.mk to be updated, and thus have a
5679 newer time stamp again, which in turn makes a pristine CVS
5680 checkout have correct time stamps.
5682 * Makefile.maint (cvs-sv): New macro, to be used..
5683 (config.guess-url_prefix, config.sub-url_prefix)
5684 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5685 point to CVS text checkout of Gnulib files.
5686 (copyright-check): Bump current year.
5687 (announcement): Do not hard-wire `./announce-gen'.
5688 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5690 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5692 (wget_files): Update config.guess, config.sub, texinfo.tex by
5693 `wget-update', now that their URLs work again.
5695 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5697 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5698 Problem noted by Paul D. Smith.
5700 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5702 * doc/autoconf.texi: Remove unused words from word list.
5703 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5704 .x-sc_trailing_space: New files.
5706 * doc/standards.texi: Sync from gnulib.
5708 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5709 `LIBOBJDIR' as experimental.
5711 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5712 with a target directory; it's internally implemented as `cp'
5713 anyway, but since Autoconf advertises the possibility to use
5714 a target directory when LN_S is `ln -s', we need to find out.
5715 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5716 analyzed by Keith Marshall <keith.marshall@total.com>.
5720 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5722 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5723 confdefs.h as-is. In general, if it has backslash-newline or the
5724 like, then it doesn't work either to sort or to remove empty
5727 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5729 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5731 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5733 * lib/autom4te.in (Automake-preselections): Preselect
5736 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5738 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5739 apostrophe within a single-quoted string, as this is the usual
5740 tradition and is easier to read than '"'"'. Don't rely on the
5741 shell treating "$/" like '$/'. Use a more-consistent indenting
5744 2006-04-09 Eric Blake <ebb9@byu.net>
5746 * tests/autotest.at (Backquote command substitution),
5747 (Multiline backquote command substitution): Remove mistaken
5748 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5750 (Parenthetical command substitution, Multiline parenthetical
5751 command substitution): here.
5753 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5755 Import macros from gnulib (often changing their name).
5757 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
5758 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
5759 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

5765 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
5766 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
5767 The manual mentions Gnulib more prominently.
5768 * doc/autoconf.texi (Gnulib): New node.
5769 (Pointers): Add Gnulib URL.
5770 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
5771 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
5773 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
5774 suggest a #define rather than a typedef for _Bool, and mention
5775 Gnulib rather than trying to substitute stdbool code.
5776 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
5777 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
5778 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

5884 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5886 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
5887 whether `set' quotes correctly: redirect stderr of the tested
5888 `set', and use a subshell, for Ultrix; use `sed' instead of
5889 `grep' for zsh `set' which may write binary output; match only
5890 at the beginning of a line, to avoid false positives.
5891 In order to avoid false positives by unrelated variables with
5892 multiline content, put the dump algorithm in a subshell and
5893 unset all variables containing newlines (except some which are
5894 special to the shell). Warn about cache variables that are

5943 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
5944 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the

6739 (Particular Programs): Likewise.
6740 (Coding Style): y is like s with respect to / and ,.
6741 (Limitations of Usual Tools): Document the weird restrictions
6742 that Posix has about { }. Use better quoting.

6831 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
6832 `AC_SUBST($1)' in the public version.
6833 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)

6859 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
6860 conftest.o, to see whether the compiler really obeys; rm the object
6861 file before and after the test and register it with ac_clean_files.

6887 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
6888 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
6889 by the function rather than ignoring it.
6890 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
6891 comparing its address. Intel's interprocedural optimization was
6892 outsmarting the old heuristic. Problem reported by
6895 2005-10-19 Stepan Kasal <kasal@ucw.cz>
6897 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
6899 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
6901 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

6904 2005-10-04 Stepan Kasal <kasal@ucw.cz>
6906 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
6907 before removing it (chmod -R u+rwx); there are three instances of this.
6909 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6910 Stepan Kasal <kasal@ucw.cz>
6912 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
6913 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
6914 make its content writable before removing it. Remove an errorneous
6915 comment from the end, where the logs of the failed tests are copied
6916 to the main log file.
6918 2005-09-27 Stepan Kasal <kasal@ucw.cz>
6920 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
6921 in case the computer is too quick. Double quote the configure.ac
6924 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
6925 problems if the testsuite were running too fast.
6927 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
6929 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
6930 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
6931 (which belong to Xt, not X itself). See Debian bug 327655.
6932 * NEWS: Mention this.
6934 2005-09-07 Stepan Kasal <kasal@ucw.cz>
6936 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
6938 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
6940 * config/move-if-change: Don't output "$2 is unchanged";
6941 suggested by Ben Elliston. Handle weird characters correctly.
6943 2005-09-06 Stepan Kasal <kasal@ucw.cz>
6945 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
6946 calls, so that the final expansion of this macro is shorter.
6947 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
6948 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
6949 the cleanup there. Use AS_VAR_* macros, to be more general.
6950 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
6952 * lib/autoconf/general.m4: Use AS_IF where appropriate.
6954 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
6956 2005-09-01 Stepan Kasal <kasal@ucw.cz>
6958 * doc/autoconf.texi (Configuration Headers): Add an index entry
6961 2005-08-26 Pavel Roskin <proski@gnu.org>

6964 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
6967 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
6969 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
6970 The previous patch didn't work, so try a better one.
6972 2005-08-26 Stepan Kasal <kasal@ucw.cz>
6974 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
6975 in the example. Reported by Bruno Haible.
6976 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
6977 "if $undefined_var;" succeeds with my shell.
6979 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
6980 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
6981 but change the m4_divert_text to m4_divert_once.
6983 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
6985 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
6986 Work around bug in Solaris /usr/xpg4/bin/awk.
6987 The bug is present in at least Solaris 8 through 10.
6989 2005-08-24 Stepan Kasal <kasal@ucw.cz>
6991 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
6992 some evil values and relying on the fact that $* concatenates the
6993 parameters by the first character from IFS.
6995 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6996 Stepan Kasal <kasal@ucw.cz>
6998 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
6999 first header appears, define AH_HEADER.
7000 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7001 Update limitations about when to call AC_CONFIG_HEADERS.
7002 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7003 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7004 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7005 ``Configuration Actions''; fix their index entries.
7007 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7008 options correctly. Process N-M as M-N if M is smaller than N.
7009 Process ranges correctly so that N-N will run only N.
7010 Sort and uniquify the tests that will be run. If there is more
7011 than one test, reinsert the banners for the tests.
7012 * tests/autotest.at (Keywords): Unmark XFAIL.
7014 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7016 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7017 before passing the macro name to AH_TEMPLATE.
7019 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7020 now opens log after option processing; in particular, --version
7021 and --help do not touch config.log.
7023 * Makefile.maint: Revert the change from 2005-08-12.
7025 2005-08-22 Stepan Kasal <kasal@ucw.cz>
7027 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out

7031 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7033 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7034 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7037 * doc/autoconf.texi (Defining Symbols, Changed Results):
7038 Prepend to LIBS, not append, in examples.
7040 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7042 When building in place, set srcdir="."; suggested by Tim Van Holder.
7044 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7045 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7046 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7047 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7048 does not mean "no --srcdir option".
7050 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7052 * tests/autoscan.at (autoscan): New file.
7053 * tests/suite.at: Use it.
7054 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7055 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7057 * tests/autotest.at (Keywords): Test keywords combinations.
7059 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7061 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7062 add "2>&1"; gzip 1.2.4 prints help on stderr.
7064 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7066 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7067 was pushdef'ed twice while popped only once. Push it only once.
7068 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7070 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7072 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
7073 prefixed by mere "===", not "configure: === ".
7075 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
7077 * Makefile.maint: Update from Bison.
7079 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7080 "<tab>" in comment, so that the point is understandable.
7082 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7084 Rewrite substantial part of lib/autoconf/status.m4.
7085 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7086 and CONFIG_COMMANDS are not processed in four separate loops.
7087 Instead, there is one main loop. This alows that the common code
7088 is expanded only once, thus config.status (and configure) is smaller.
7090 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7091 the AC_LIST_FILES and cousins macros are no longer used.
7093 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7094 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7095 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7096 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7097 contain the initialization, nor the for loop, nor the associated
7098 commands; all these go to ...
7099 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7100 _AC_OUTPUT_CONFIG_STATUS.
7101 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7102 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7103 (_AC_OUTPUT_FILE): The creation of the sed script ...
7104 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7105 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7106 _AC_OUTPUT_MAIN_LOOP.
7107 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7108 _AC_CONFIG_COMMANDS): Use ...
7109 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7110 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7111 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7112 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7113 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7114 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7116 (_AC_CONFIG_UNIQUE): Update.
7117 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7118 Replaced by this ...
7119 (_AC_LIST_TAGS): ... new common macro.
7120 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7121 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7122 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7123 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7124 this didn't belong to the `config commands' section.
7125 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7126 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7127 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7128 to the `config commands' section either.
7129 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7130 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7132 ... and many changes to the comments nearby.
7134 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7135 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7136 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7137 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7138 (#define header templates): The comment at the top of the generated
7139 header now includes the name(s) of the source file(s).
7141 Several unrelated small changes:
7143 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7144 parameter to AC_DIAGNOSE.
7145 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7146 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7147 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7148 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7150 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7151 in AC_OUTPUT doesn't double-quote it either.
7152 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7155 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7157 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7158 versions of Portland Group compiler produce single- and double-quoted
7159 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7160 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7162 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7164 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7165 This is a corrected version of yesterday's patch.
7167 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7169 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
7170 path, too; insert a "===" to emphasize the line.
7172 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
7173 ac_cv_build_alias to ac_build_alias.
7174 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7176 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7177 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7178 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7179 (AC_ARG_VAR): ... here.
7180 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7183 Keep a list of all precious variables and process them with one simple
7184 for loop, instead of expanding all commands, or, OTOH, complicated

7247 configure_input, top_builddir, srcdir, etc.
7248 * lib/autotest/general.m4 (AT_INIT): Likewise, for

7320 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

7341 variable into diagnostic. Make the diagnostic an error, not a warning,
7342 because we really don't support spaces and suchlike in dir names.
7343 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7344 Don't worry about backslashes in srcdir; it can't happen now.

7388 * doc/autoconf.texi:
7389 Don't mention Solaris versions so much, if a
7390 problem is common to all extant versions of Solaris. Say "SunOS
7391 4" instead of "SunOS" for SunOS 4.
7392 (awk): Mention more of the limitations of traditional Awk.

7435 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7436 -u, since it outputs chatter if the input files are the same.
7437 Problem reported by Ralf Menzel.
7439 2005-06-08 Derek Price <derek@ximbiot.com>
7441 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7442 renaming them since they are about to be redefined anyhow.
7444 2005-06-08 Derek Price <derek@ximbiot.com>
7446 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7447 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7448 Move m4_undefine to alphabetical order.

7453 * doc/autoconf.texi (Introduction): Likewise.
7454 Reword to avoid some formatting glitches.
7455 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7456 Clarify explanation of HP compiler bug.
7457 Redo example output tp match current CVS snapshot.
7458 Use @example.org in email addresses when the examples
7459 might get inadvertently cut-and-pasted into user code.
7460 Remove example of autom4te usage that doesn't seem to work now.
7461 Use modern AC_INIT (except when the example is meant to be
7462 shown with Autoconf 2.13).
7463 Update ksh info for Solaris 9 and later.
7465 Modernize description of Automake versions a bit.
7466 Don't claim a future version of Autoconf is near.

7476 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7477 Tru64 ksh pattern matching bug. Reported against Libtool by
7478 Albert Chin <libtool@mlists.thewrittenword.com> and
7479 Nicolas Joly <njoly@pasteur.fr>.
7481 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7483 m4_cdr of one-member list was [[]] (one-member list containing an
7484 empty string) instead of [] (an empty list. Callers were skewed to
7485 match this misbehaviour. As a consequence of this:
7486 - m4_foreach([x], [], [foo]) expanded to `foo', while
7487 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7488 This bug has been fixed:
7490 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7491 expand to an empty string; print error msg if called without
7493 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7494 misbehaviour; handle [] and [[]] correctly.

7504 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7505 swallow records with more than 99 fields.
7506 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7507 parse the long line.
7509 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7511 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7512 swallow literals longer than 399. Reported by Ralf Wildenhues.

7518 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7519 to gfortran, and make these the first two compiler names

7524 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).

7546 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7547 now contain newlines, and substituted files must be referenced on
7548 a line alone; the sed scripts to substitute them are now very

7551 commands can be put in a sed script portably.

7621 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7622 argument to m4_foreach. I guess it was necessary in the past,

7706 * doc/autoconf.texi (Autoconf Language): Be more precise about
7707 quoting rules. Problems noted by Stepan Kasal.
7708 Also, throughout this document, be more careful about white space.
7709 "blank", "white space", and "space" all have different meanings
7710 and we should be careful to say what we mean.

7730 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
7731 set by latest automake.
7733 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7735 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
7736 outputs 0 on GNU/Linux these days.
7738 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
7740 * doc/autoconf.texi (Autoconf Language): Add more description

7746 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
7749 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
7750 by AC_DEFINE; it was a mistake.
7751 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
7753 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7755 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7757 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7759 * doc/autoconf.texi (External Software): Quadrigraphs are not
7760 processed correctly in AS_HELP_STRING; avoid this in the examples.
7761 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7762 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7763 comment and reduce m4_default([foo], []) to [foo].
7764 (m4_strip): Update the explanation.
7766 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7768 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7769 Remove core.conftest.* too; it's generated by Tru64 5.1.
7770 Problem reported by Jennis Pruett.
7771 * lib/autoconf/functions.m4
7772 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

7820 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
7821 Merge `-z option' as well for the benefit of Solaris link flags. Pass
7822 whole-archive (-zallextract, -zdefaultextract) options in the hope of
7823 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
7824 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
7826 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
7828 * NEWS: The configure command now warns you if you attempt to use
7829 a directory whose name contains a special character like space,
7831 * doc/autoconf.texi (Installation Directory Variables): Allow
7832 "," in file names. Do not use \@; it's not a portable regexp.
7833 * bin/Makefile.am (edit): Likewise.
7834 * lib/Makefile.am (edit): Likewise.
7835 * tests/Makefile.am (edit): Likewise.
7836 * tests/semantics.at: Likewise.

7841 unportable file names.
7842 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
7844 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
7845 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
7846 ac_pwd, and quote srcdir.
7847 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
7849 * doc/autoconf.texi: Fix some systematic formatting problems.
7850 ".)" needs a following @: if not at the end of a sentence, and
7851 similarly for "!)". "etc." should be preceded by a comma.
7852 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
7854 2005-03-22 Bruno Haible <bruno@clisp.org>
7856 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
7857 argument is often called 'build-aux'.
7859 2005-03-07 Stepan Kasal <kasal@ucw.cz>
7861 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
7862 macro AC_TRY_LINK is obsolete.
7863 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
7866 2005-02-24 Stepan Kasal <kasal@ucw.cz>
7868 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
7869 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
7870 from a Common Lisp's `cl'.
7871 (AC_PROG_CXX): Behave according to the documentation: don't
7872 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
7873 make the variable CCC precious; use `cl.exe', not `cl'.
7875 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7876 Alexandre Duret-Lutz <adl@gnu.org>
7878 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
7879 /dev/null, as "configure" shouldn't read stdin, and this insulates
7880 us from problems (e.g., when testing for "cl"). Also, do this
7881 redirection before invoking "hostname" or "uname", and keep the
7882 original input stream available via...
7883 (AS_ORIGINAL_STDIN_FD): ... this new macro.
7884 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

7896 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
7897 newline if neither \c nor -n work, as that would output two
7898 newlines. Prefer -n to \c. Reported by Stepan Kasal.
7900 2005-02-12 Stepan Kasal <kasal@ucw.cz>
7902 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
7903 This causes that any required macros inside will get before the if.
7904 * doc/autoconf.texi (autom4te.cache): A typo.
7906 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
7908 Undo previous change, except keep the change to
7909 lib/autoconf/programs.m4 that replaced grep with shell
7910 pattern-matching. This is because net-snmp configure reads stdin.
7911 Reported by Noah Misch.
7913 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
7915 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
7916 from /dev/null, as "configure" shouldn't read stdin, and this
7917 insulates us from problems (e.g., when testing for "cl").
7918 Suggested by Alexandre Duret-Lutz. Also, do this redirection
7919 before invoking "hostname" or "uname".
7920 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7921 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
7922 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
7923 "</dev/null" since it's now done at the top of 'configure'.
7924 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7925 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7926 Also, replace grep with shell pattern-matching, to save a process.
7928 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
7930 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7931 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
7932 avoid thinking that Allegro Common Lisp's "cl" command is a C++
7935 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
7937 * doc/autoconf.texi (Limitations of Usual Tools): Document that
7938 grep -q isn't portable. Improve grep -s explanation.
7939 Problem reported by Dan Manthey.
7941 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
7943 * doc/autoconf.texi (Special Shell Variables): Clarify
7944 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
7946 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
7948 * doc/autoconf.texi: Use @acronym for DJGPP.
7949 Fix some @code's that should have been @env's, and vice versa.
7950 Sort environment variable names.
7951 Mention that shells no longer inherit IFS.
7952 Don't recommend PATH_SEPARATOR=';' so strongly.
7953 Mention that $RANDOM might expand to the empty string.
7954 "symlink" and "soft link" -> "symbolic link".
7955 Improve mktemp description (reported by Bruno Haible).
7957 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
7959 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
7960 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
7962 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
7965 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
7967 * NEWS: Mention AT_COPYRIGHT.
7969 * tests/local.at (AT_CMP): Use diff directly on input files rather
7972 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
7973 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
7975 2005-02-04 Noah Misch <noah@cs.caltech.edu>
7976 and Paul Eggert <eggert@cs.ucla.edu>
7978 * tests/autotest.at (Empty test suite): New test.

7987 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
7988 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
7989 (Standard regular expressions): New test.
7990 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
7991 excess test name quoting.
7992 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
7993 CPPFLAGS to `configure' instead of setting it in `configure'.
7995 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
7996 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

8030 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8031 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8033 Try not to generated lines of unlimited length, as POSIX places a
8034 2047-byte limit on line length of portable text files.
8035 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8036 Use newline as a separator, not space.

8045 are restored after function return.
8047 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
8049 * doc/autoconf.texi (Special Shell Variables): Mention _,
8050 BIN_SH, DUALCASE. Say that variables other than "status" are safe
8051 if they contain a lower-case letter. The DUALCASE problem was
8052 reported by Ralf Wildenhues.
8054 * bin/autoconf.as: Don't exit with status 0 after write failure
8055 with --help or --version.

8069 * man/Makefile.am (.x.1): Go back to the simple solution, but take
8070 care to echo the commands, so the user knows what's going on.
8071 Modified from a suggestion by Stepan Kasal.
8073 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

8094 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8095 Update the long comment explaining it.
8097 m4_require no longer writes an ``is required by'' line to the
8098 execution stack. It contains only one bit of non-redundant
8099 information: that the macro was required, not called. And even

8523 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8524 "char c = '\200';" rather than "char c = 0x80;" as the

8585 simplify the examples and improve their quoting.
8587 2004-11-13 Stepan Kasal <kasal@ucw.cz>
8589 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
8590 the $1_found variable, don't test whether the file is executable;
8591 Both things are checked ...
8592 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
8593 the former ``test -f''.
8594 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
8596 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

8608 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
8609 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
8610 variants", "Unix", and some related minor wording fixups.
8612 (Shellology, Special Shell Variables): Document that the Zsh
8613 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
8614 to Alexandre Duret-Lutz for this info.

8623 of putenv. Problem reported by Michael Wardle.
8625 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
8627 * doc/autoconf.texi (auindex): New macro.
8628 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
8629 Problem reported by Stepan Kasal.

8635 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
8637 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
8638 readable; it's not true in OS/2-emx.
8640 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
8642 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
8643 "/usr/include", clear ac_x_includes instead of leaving it as "no"
8644 (trivial change). Problem and patch reported by Andrew Church in:
8645 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
8647 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

8674 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
8675 texinfo.tex for now (done by hand now).
8676 * Makefile.maint (wget_files, cvs_files):
8677 Remove ansi2knr.c; nobody uses it.
8678 (ansi2knr.c-url_prefix): Remove.
8679 (cvs-update): Fix test for failure. I don't know why it ever
8682 * doc/autoconf.texi: Update URLs, some of which went stale.
8683 Use @uref rather than @href.
8685 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
8686 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
8688 * config/config.guess, config/config.sub, config/elisp-comp,
8689 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
8690 doc/fdl.texi, doc/standards.texi: Sync with master copy.

8700 Use "file name" rather than "filename" or "path",
8701 to be consistent with the terminology of the GNU coding standards.
8703 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
8705 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
8706 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
8707 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
8708 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
8710 More fixes to support spaces in the name of the build directory.
8711 This isn't a complete fix but it's an improvement.
8713 * bin/autoconf.as (autom4te_options): New var.
8714 Use it instead of appending to AUTOM4TE, so that we can allow
8715 spaces in the build directory's absolute name.
8716 * bin/autoheader.in ($autoconf): Allow spaces in file names.
8717 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
8718 AT_CHECK_NOESCAPE): Likewise.
8719 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
8720 main program): Likewise.
8722 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
8724 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

8730 * doc/autoconf.texi (Function Portability): Document isinf and
8731 and isnan. From a suggestion by Kevin Ryde.
8733 * lib/Autom4te/General.pm (END): Return correct exit status even
8734 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
8736 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
8738 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
8739 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
8740 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
8742 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
8744 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
8745 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
8746 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
8747 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
8748 * lib/autom4te.in (Automake-preselections): Preselect
8749 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8751 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8753 * lib/autom4te.in (Automake-preselections): Preselect
8754 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
8757 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
8759 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
8761 * doc/autoconf.texi (Shellology): Mention BIN_SH.
8762 Document problem with "`""`" in pdksh POSIX mode.
8764 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
8766 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
8767 with pdksh, too. Problem reported by Patrick Welche via
8769 * doc/autoconf.texi (Shellology): Note that set -o posix is
8770 useful for pkdsh, too.
8772 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
8774 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8775 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8776 Don't fail if ENV or BASH_ENV is readonly.
8777 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
8778 etc. are read only. Problem reported by Ludovic Courtes.
8780 2004-06-23 Noah Misch <noah@cs.caltech.edu>
8782 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
8783 zsh, disable GLOB_SUBST to avoid backslash handling problems.
8786 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
8788 * doc/autoconf.texi (File System Conventions): Warn about
8789 names like "aux". Problem reported by Eric Blake.
8791 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
8792 by zero instead of array size, so that we can use any arithmetic
8793 constant expression (instead of requiring an integer constant
8794 expression). This allows us to test expressions like DBL_MAX <
8795 LDBL_MAX, which didn't conform to the C standard using the old
8797 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
8798 now that we can do floating-point tests at compile time.
8800 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8802 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8803 and LDBL_EPSILON, as the resulting expression isn't an
8804 integer constant expression and violates the C standard.
8805 Problem reported by Nelson H. F. Beebe. Also, check
8806 for "L" suffix, and check that long double doesn't have
8807 worse range or precision than double, that mixed-mode
8808 arithmetic doesn't generate a diagnostic, that double
8809 constants fit in long double.
8811 2004-06-03 Kevin Ryde <user42@zip.com.au>
8813 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
8814 malloc(0) and realloc(NULL,size).
8816 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
8819 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
8821 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
8822 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
8825 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8827 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
8828 can be rewritten using if-then-else. Suggested by Bruno Haible.
8830 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
8832 * doc/autoconf.texi (testsuite Scripts): Fix typo.
8833 Problem reported by Stepan Kasal.
8835 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8837 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
8838 change). Patch reported by Ralf Wildenhues in
8839 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
8841 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8842 function F exists if the compiler and linker let you compile an
8843 expression like (F != 0). Recent versions of GCC optimize away
8844 the reference to F in that case, since every function address must
8845 be nonzero, so the link succeeds even if F does not exist.
8846 Problem reported by Manu in
8847 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
8849 * doc/autoconf.texi (Systemology): Standardize on the spelling of
8850 "Unix". Many uses changed.
8851 (Limitations of Builtins): Explain better why the ! command isn't
8854 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>

8857 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
8859 2004-05-19 Kevin Ryde <user42@zip.com.au>
8861 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
8862 referencing AC_FUNC_STRERROR_R.
8864 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
8865 note pessimistic assumption when cross compiling.
8867 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
8869 * doc/autoconf.texi (Limitations of Make): Note that BSD make
8870 (until 2004) invoked subcommands with sh -e, contra POSIX.
8871 Reported by Kevin Ryde.
8873 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
8875 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
8876 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
8877 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
8878 `test -f " /usr/bin/grep"', which _always_ failed.
8879 (AC_PROG_SED): Ditto bogus PATH fix.
8880 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
8881 requires that grep correctly supports _multiple_ `-e' options, rather
8882 than stating only that grep should accept `-e'.
8884 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
8886 Port to C99, which requires that 'exit' be declared.
8888 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
8889 to ensure that stdlib.h is included.
8890 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
8891 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
8892 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
8893 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
8894 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
8895 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
8896 when using 'exit' in a test; C99 requires that 'exit' be declared.
8898 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
8900 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
8901 now prefers 'grep' implementations that accept -e.
8902 (Limitations of Usual Tools): Describe problems of traditional
8903 egrep and fgrep with long input lines, and of traditional grep
8905 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
8906 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
8907 All callers changed. Append /usr/xpg4/bin to the PATH, for
8909 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
8910 the user with complaints about multiple -e options.
8911 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
8912 Define it with AC_PROG_GREP.
8913 * configure.ac (AC_PROG_GREP): Add.
8914 * lib/freeze.mk (GREP): New macro.
8916 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
8918 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
8919 a possible candidate only after all others fail, rather than
8920 consulting it first. This improves backward compatibility by
8921 better reflecting the way shell selection occurred in previous
8922 versions of Autoconf, and should help to avoid triggering latent
8923 problems in other packages, such as the one in Automake where zsh
8924 is not handled robustly:
8925 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
8926 Although it is not Autoconf's responsibility to work around
8927 problems in Automake, it nevertheless makes sense to avoid
8928 introducing unnecessary incompatibilites.
8930 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
8931 Gary V. Vaughan <gary@gnu.org>
8933 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
8934 how deeply nested we are when a suitable tool is found, set the
8935 ac_path_TOOL_found flag.
8936 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
8937 nested we are in this macro. Break out of all 3 nested loops if
8938 ac_path_TOOL_found is set.
8940 2004-04-21 Gary V. Vaughan <gary@gnu.org>
8942 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
8943 of the _AS_PATH_WALK loop too if GNU flavor is found.
8945 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
8947 * doc/autoconf.texi (Limitations of Make): Update documentation
8948 for `$<'. New entry `Long lines', based on a report from Simon
8949 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
8950 paragraph about DJGPP, based on a mail from Richard Dawe.
8952 2004-04-20 Paul Eggert <eggert@twinsun.com>
8954 * tests/c.at (C keywords): Don't assume that GCC supports
8955 "restrict" and "inline", as sufficiently-old GCC versions do not
8956 (also, GCC configured to be in pedantic C89 mode does not).
8957 Problem reported by Sumit Pandya in:
8958 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
8960 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
8961 consider -g to work if it generates warnings when plain compiles
8962 don't. Problem reported by Braden McDaniel in:
8963 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
8965 * doc/autoconf.texi (Slashes): New section, to document a problem
8966 reported by Jim Meyering in:
8967 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
8969 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
8970 linker output files before linking, to work around IRIX 6 linker bug.
8971 Problem reported by Rainer Orth in:
8972 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
8974 2004-04-20 Gary V. Vaughan <gary@gnu.org>
8976 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
8977 best tool so far counter rely on the tool path variable name to
8978 avoid checks for one tool being affected by the results of running
8979 the length check on a previous tool.
8981 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
8982 match expression argument, as different greps have different
8983 regular expression flavours.
8984 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
8986 (AC_PROG_EGREP): Pass 'EGREP$'.
8987 (AC_PROG_GREP): Pass 'GREP$'.
8989 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
8991 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
8992 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
8994 2004-03-29 Paul Eggert <eggert@twinsun.com>
8996 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
8997 Types, Specific Compiler Characteristics, System Services,
8998 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
8999 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9000 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9001 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9003 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
9004 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
9005 AC_TYPE_OFF_T): Likewise.
9006 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
9009 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
9010 pacify libtool 1.5.2. Fix quoting problems in sed command.
9012 2004-03-28 Paul Eggert <eggert@twinsun.com>
9014 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9015 now defines HAVE_DECL_TZNAME if it is declared, when
9016 HAVE_STRUCT_TM_TM_ZONE is not defined.
9017 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9018 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9021 2004-03-28 Steven G. Johnson <stevenj@fftw.org>

9089 Problem reported by Anthony N. Frasso in
9090 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

9119 AC_SUBST provides no portable way to escape literal newlines.
9121 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9122 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9123 Darwin uses -lcrt2.o and there's little point to cataloging all
9124 the system variants. Partial fix reported by Andreas Waechter in:

9149 Eric Sunshine <sunshine@sunshineco.com>

9200 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9201 2003 (except 1997) to the list of copyright years. This undoes
9202 the 2003-05-22 change, which removed the older years from the list.
9203 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

9216 _AC_PROG_GREP, and AC_PROG_SED.

9249 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9250 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9251 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9252 not <inttypes.h>. Problem reported by Tim Mooney in
9253 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9254 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9257 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9258 otherwise "make check" fails because it forbids cmp (I guess
9259 because cmp treats files as binary on DOS-like systems).

9262 have changed in 2004.

9272 2004-01-15 Paul Eggert <eggert@twinsun.com>
9274 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9275 -std1 disables some useful extensions on Tru64. Problem reported

9279 2004-01-14 Paul Eggert <eggert@twinsun.com>
9281 * doc/autoconf.texi (Programming in M4sh): Document that
9282 AS_MKDIR_P succeeds if the destination is a symbolic link
9283 to an existing directory.
9284 (Limitations of Usual Tools): Note that mkdir -p might not
9285 succeed on symlinks to directories.
9287 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9289 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

9303 2004-01-09 Paul Eggert <eggert@twinsun.com>
9305 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9306 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9307 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9308 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9309 AC_COMPILE_IFELSE, since we now assume our caller invokes
9310 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9311 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9312 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9313 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9315 2004-01-07 Paul Eggert <eggert@twinsun.com>
9317 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9318 `"'...'"`, as it's confusing (and I suspect it may not work on
9319 some platforms). The code was incorrect anyway, as it assumed
9320 that \$ evaluated to itself in that context. Reported by
9321 Alexandre Duret-Lutz.
9323 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9325 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

9355 Bug reported by David Relson in
9356 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9358 * Makefile.am (autom4te-update):
9359 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

9375 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9376 -c -o might not work. From a suggestion by Kevin Ryde.
9377 (C Compiler, Generating Sources, Limitations
9378 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9379 Don't put '-o' after non-options, as POSIX doesn't allow this.
9380 Mention that cc's name might be gcc or c89 or whatever.
9382 2004-01-04 Kevin Ryde <user42@zip.com.au>

9391 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9393 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9394 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
9395 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
9396 explanation clearer.

9407 * tests/atlocal.in: Store the result here.

9677 Problems reported by Eric Sunshine.
9679 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
9681 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
9682 -mGLOB_options_string stuff for Intel ifc, which can cause
9683 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

9704 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
9706 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
9707 cache variable instead of $G77 to decide whether to include -O2,
9708 since $G77 is specific to Fortran 77.
9710 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9712 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
9713 free" flag. Re-order flags tested into rough order of popularity.
9715 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9717 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
9718 arguments so that it can be used with syntax identical to

9786 Problem reported by Lars J. Aas in
9787 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
9788 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
9789 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

9792 2003-09-26 Akim Demaille <akim@epita.fr>
9794 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
9795 directory for AC_CONFIG_COMMANDS' first argument exists.
9796 This makes valid the invocation of _AC_SRCPATH that follows.
9797 Reported by Eric Sunshine.
9798 * doc/autoconf.texi (Configuration Commands): Adjust.
9800 2003-09-26 Akim Demaille <akim@epita.fr>

9821 The test suite are sometimes assigning timings incorrectly.
9822 Reported by Henk Krus.
9823 Diagnosed by Nicolas Joly.
9825 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
9827 Instead of making AT_help a sequence of assignments to grow
9828 $at_help_all, just make AT_help_all be the growing contents of
9829 $at_help_all, and make a single assignment in...
9831 (at_times_skip): Flip the meaning and rename as...
9833 (AT_INIT): When summarizing the test that ran, remove
9834 $at_times_file after use, and check it is present before trying to

9841 * bin/Makefile.am (edit): Handle '@configure_input@'.
9842 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
9843 (ifnames): chmod -w.
9844 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
9845 executables, not bin/ executables! Otherwise all the magic needed
9846 to find non installed files is turned off. This caused a failure
9847 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
9848 as found in its environment (sent by tests/autoreconf): pointing
9849 to bin/autom4te that could not find its files.
9850 * tests/mktests.sh: Force the replacement of generated files, for
9851 the sake of "mv" program that are interactive when overwriting a
9853 * config/install-sh: Upgrade from CVS Automake.
9855 2003-09-23 Paul Eggert <eggert@twinsun.com>

9950 correspond to all the old F77 macros, with output variables FC,
9951 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
9952 available dialect, but older dialects can be specified. There are
9953 new macros AC_FC_SRCEXT to set the source extension, and
9954 AC_FC_FREEFORM to accept free-form source files.

9989 * tests/m4sugar.at (cross_warning): Make sure to enable the
9990 output, so that we can track spurious m4sugar output.
9991 * tests/local.at: Require 2.57.
9992 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
9993 are defaulted by AT_CHECK anyway.
9994 Use AT_CHECK_AUTOM4TE.

10042 (local-check): New.
10044 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
10045 * configure.ac: Require Automake 1.7.6.

10049 Output stack traces in warnings.
10051 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
10052 Replace the former...
10053 (m4_warn): Pass the call stack to _m4_warn.
10054 * bin/autom4te.in: Adjust to output the call stack.
10055 * tests/m4sugar.at (m4@&t@_warn): Adjust.
10057 2003-08-22 Akim Demaille <akim@epita.fr>
10059 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.

10062 2003-08-21 Akim Demaille <akim@epita.fr>
10064 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
10065 (&verbose): Remove.
10066 (&getopt): Adjust the note and verb channels, depending upon
10068 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
10069 * bin/autoupdate.in: Adjust.
10070 Use &verb, not &verbose.
10072 2003-08-21 Akim Demaille <akim@epita.fr>
10074 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10076 ($help): Use Autom4te::ChannelDefs::usage.
10077 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10078 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10080 2003-08-21 Akim Demaille <akim@epita.fr>
10082 First stab at preserving warnings between calls to autom4te,
10083 including when the cache is used.
10085 There are still several issues: (i) there are too many runs of m4
10086 (one for include, one for warnings, and some more), (ii) warnings
10087 spreading on several lines are not handled gracefully, (iii) the
10088 code meant to have the call stack display for errors does not work
10089 (its handling should move from m4 to autom4te).
10091 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10093 (@preselect): Add m4_warn.
10094 ($exit_status): Remove, use $exit_code.
10095 ($help): Use Autom4te::ChannelDefs::usage.
10096 (&handle_m4): No longer define the m4_warnings.
10097 At each run, extract and report the warnings.
10098 Always cache the result, including if the exit status is on
10099 failure, since if nothing changes, we should result in the same
10100 failure, hence we can use the cache.
10101 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10102 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10104 (m4_warn): Redefine as a do-nothing: it is its invocation that
10105 matters, as warnings are now reported via traces.
10106 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10107 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10108 the latter reveals calls to the former.
10112 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10114 2003-08-21 Akim Demaille <akim@epita.fr>

10125 (&usage): Return a string, not a side effect.
10126 (cross): New warning category.

10132 ($configure_ac): Remove.
10133 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10134 (&catfile): Remove.
10135 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10136 * bin/autoscan.in: Adjust.
10138 2003-08-20 Akim Demaille <akim@epita.fr>
10140 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
10141 Reported by Alexandre Duret-Lutz.
10143 2003-08-20 Akim Demaille <akim@epita.fr>
10145 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10146 * bin/autom4te: Adjust.
10147 In particular, be Autoconf tools are really silent when properly
10148 working, bind the verbosity of the 'note' channel to $verbose.
10149 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10150 (&xsystem, &contents): Remove, since they are exported by...
10151 * lib/Autom4te/FileUtils.pm: this.
10153 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10154 * lib/Autom4te/FileUtils.pm: here.
10156 2003-08-20 Akim Demaille <akim@epita.fr>
10158 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm

10212 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
10213 shorter column three. Add DESCRIPTION to log file content.
10215 2003-08-13 Derek Price <derek@ximbiot.com>
10217 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

10250 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to

10271 2003-06-23 Akim Demaille <akim@epita.fr>
10273 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10274 not all of them. This fixes 1. the fact that when testing
10275 Autoconf there are many many config.log, 2. the incorrect use of
10276 top_srcdir to find config.log.
10277 Don't mix the detailed output of failed test with the summary of
10278 failures. Rather, append detailed log afterwards.
10280 2003-06-23 Akim Demaille <akim@epita.fr>
10282 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
10283 always run: output config.log on $at_group_log.
10285 2003-06-23 Akim Demaille <akim@epita.fr>
10287 * tests/torture.at (#define header templates): Don't use quotes in

10361 (handle_exec_errors): New function. Work around $! being
10362 altered by WEXITSTATUS.
10363 (xqx, xsystem): Use handle_exec_errors.
10365 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10367 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10368 Do not call `_exit()', simply modify `$?'.
10369 (xsystem): Reset $! before running system, and check it afterward.
10370 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10371 63 for version mismatches.
10373 2003-05-23 Akim Demaille <akim@epita.fr>
10375 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10376 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in

10397 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10398 Remove `#include <stdlib.h>' from the list; we should never
10399 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10400 resulting namespace pollution would cause other tests to fail.
10401 Configure scripts run with some older versions of g++ and HP's
10402 aCC would fail due to such an #include. Problems reported by
10403 Matthew Mueller in <http://bugs.debian.org/120704> and by
10405 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10406 In the test, use the test declaration before including <stdlib.h>,
10407 as that's closer to how it'll be used.
10409 2003-05-23 Akim Demaille <akim@epita.fr>
10411 * doc/autoconf.texi (Header Portability): ucred.h.
10414 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10416 Overhaul Autotest's logging: generate separate log files
10417 in testsuite.dir/NNN/testsuite.log, and append them to
10418 testsuite.log instead of re-running the test verbosely.
10420 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10421 file descriptor, write 0 to at_status_file instead of setting
10422 at_status=0, initialize some new variables (at_status_file,
10423 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10424 to rerun the tests, instead append the at_group_log to the
10425 at_suite_log when a test fails.
10426 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10427 with the AS_MESSAGE_LOG_FD redirected to stdout.
10428 (AT_CLEANUP): save the output status in $at_status_file
10429 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10430 its original place.
10431 (AT_CHECK): since tests are run with a redirected stdout,
10432 and used to be re-run in verbose mode, turn some $at_verbose
10433 into echo, and don't redirect the output of testing stdout
10436 * lib/autotest/autoconf.texi (testsuite Scripts): Update

10557 2003-05-06 Akim Demaille <akim@epita.fr>
10559 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10560 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10561 by aclocal.m4 is changed it might require the importing of another
10562 m4 extension file, i.e., aclocal must be run.

10565 (&parse_args): Use --force with aclocal if required and supported.

10581 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10582 seperator with m4_append_uniq(). It doesn't work.
10583 (AT_CLEANUP): Add `;' to end of at_help_all.

10665 * tests/torture.at (Configuring subdirectories): Require aclocal
10666 1.4, otherwise the test fails, as it does support configure.ac.

10755 * bin/ifnames.in: Add final newline to help and version messages.
10757 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
10758 to cope with DOS-style absolute paths, when constructing
10761 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
10762 When constructing paths with IFS=:, quote the path. If we're
10763 constructing a DOS-style absolute path, we don't want to split it
10766 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
10769 2003-02-25 Pavel Roskin <proski@gnu.org>

10786 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
10787 format starting with "-".
10789 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
10791 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
10792 is not portable inside Makefile.
10794 2003-02-20 Akim Demaille <akim@epita.fr>
10796 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
10797 compiler says yeah, but preproc says nope, compiler is right.
10798 Conversely, prompt the reader to send a bug report to the
10799 maintainers of the package, not of Autoconf.

10803 * bin/autoreconf.in (autoreconf_current_directory): Properly
10804 handle an empty aclocal.m4.

10809 $ac_prefix_program.
10812 2002-12-23 Paul Eggert <eggert@twinsun.com>
10814 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10815 innocuous variant befor including <limits.h> or <assert.h>. This
10816 works around a bug reported by Albert Chin: HP-UX 11i
10817 (and earlier versions) have a <limits.h> that declares
10818 gettimeofday and many other functions.
10820 2002-12-03 Paul Eggert <eggert@twinsun.com>
10824 * NEWS, configure.ac: Update version.
10826 * doc/fdl.texi: Upgrade to FDL version 1.2.
10828 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
10829 nontrivially in main's body, so that f's external declaration is
10830 not optimized away in AIX. This should fix the bug reported by
10832 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
10834 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10835 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10836 defined, to support freestanding compilers. This should fix the
10837 bug reported by Momchil Velkov in
10838 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10840 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10841 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

10852 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
10853 \(.*\) match is too long and there is something more to be checked.
10854 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

10872 Update from masters.
10874 2002-11-14 Akim Demaille <akim@epita.fr>
10876 * Makefile.maint: Sync with Bison, i.e.:
10877 (po-check): Scan .l and .y files instead of the
10878 .c and the .h files that they generate. This fixes the bug
10879 reported by Tim Van Holder in:
10880 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
10881 Look for N_ as well as for _. Try to avoid matching #define for
10885 2002-11-14 Akim Demaille <akim@epita.fr>
10887 * doc/autoconf.texi (C Compiler): Compiling several files at once.

10890 2002-11-14 Akim Demaille <akim@epita.fr>
10892 * doc/autoconf.texi (C Compiler): Solitary backslashes.
10893 From Paul Eggert and Albert Chin-A-Young.
10895 2002-11-14 Kevin Ryde <user42@zip.com.au>
10897 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
10898 than assigning in main, to avoid HP cc +O3 optimizing it away.
10900 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
10902 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
10903 option. Process --recheck after parsing all options. Pass -q
10904 option to configure on --recheck.
10905 (AC_OUTPUT): Pass -q from configure to config.status.
10906 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
10907 arguments to record.
10908 * doc/autoconf.texi (config.status Invocation): Document
10909 config.status -q option.
10911 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
10913 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
10914 Makefile.in if Makefile.am exists.
10915 (output): Strip `.am' from Makefiles. Don't
10916 output AC_CONFIG_FILES if no Makefiles were found.
10918 2002-11-07 Akim Demaille <akim@epita.fr>
10920 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
10921 (local_updates): New.
10922 * Makefile.maint: Update, from CVS Bison.
10923 (local_updates): New.
10925 2002-11-06 Akim Demaille <akim@epita.fr>
10927 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
10928 declaration in extern "C" too.
10929 Reported by Roberto Bagnara.
10931 2002-11-06 Akim Demaille <akim@epita.fr>
10933 * tests/torture.at (Configuring subdirectories): Don't use grep
10935 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
10936 Reported by Ezra Peisach.
10938 2002-11-05 Akim Demaille <akim@epita.fr>
10940 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
10942 We _have_ to stop using the old compatibility scheme that tried to
10943 avoid useless backslashes because Libtool 1.4.3 contains a
10944 AC_DEFINE([error_t], [int],
10945 [Define to a type to use for \`error_t' if it is not
10946 otherwise available.])
10947 We _have_ to quote the single quote and backslashes with \. The
10948 old compatibility scheme saw that ` was backslashed, and therefore
10949 did not quote the single quote. Hence before this patch, Autoconf
10950 was not compatible with Libtool.
10952 2002-11-04 Paul Eggert <eggert@twinsun.com>
10954 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

10963 * Makefile.maint (update, cvs-update, po-update, do-po-update):
10965 * config/texinfo.tex: Update.
10967 2002-11-03 Akim Demaille <akim@epita.fr>
10969 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
10971 (&autoreconf): here.

11341 Reported by Alexandre Duret-Lutz.
11343 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

11348 (&up_to_date): If a file that was included according to the cache

11363 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11364 if some file was changed instead of `print'.
11365 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

11399 file name to enable parallel executions.
11400 From Sam Varshavchik.
11402 2002-10-08 Akim Demaille <akim@epita.fr>
11404 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11405 aclocal invocation, as Gettext macros might not be visible to
11407 Instead of blindly running autopoint, scan configure.ac (not the
11408 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11409 Reported by Paul D. Smith.
11411 2002-10-08 Paul Eggert <eggert@twinsun.com>
11413 Work around problems found when POSIXLY_CORRECT=1 is set.
11414 None of this seems to have anything to do with POSIX, really,
11415 but it's how Perl getopt works.
11416 * bin/autom4te.in (parse_args): Configure GetOpt with
11418 * doc/autoconf.texi (Invoking autom4te):
11419 --warning -> --warnings.

11441 * tests/torture.at (Configuring subdirectories): Be robust to
11442 users who use config.site to require for a cache: in this case,
11443 the two last configure runs, using two different sets of
11444 arguments, trigger a legitimate error.
11446 2002-09-28 Akim Demaille <akim@epita.fr>

11479 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11480 (.m4.m4f): Don't pass --prepend-include, since that's done by
11481 tests/autom4te itself.
11482 * lib/autoscan/Makefile.am: Include freeze.mk.
11483 (autoscan.list): New target --this file is no longer a source.
11484 (autoscan.pre): New file.
11486 2002-09-28 Akim Demaille <akim@epita.fr>
11488 * bin/autoscan.in (@kinds): Make them singular.
11490 (&init_tables): When --debug, report the list of rules to ease
11491 tracking changes in autoscan.list.
11492 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11494 2002-09-28 Akim Demaille <akim@epita.fr>

11500 * bin/autoscan.in (&init_tables): Adjust.
11502 2002-09-28 Akim Demaille <akim@epita.fr>
11504 * lib/autoscan/functions, lib/autoscan/headers,
11505 * lib/autoscan/identifiers, lib/autoscan/makevars,
11506 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11507 `functions' line is now prefixed with `function:'.
11508 * bin/autoscan.in (&init_tables): Adjust.
11510 2002-09-28 Akim Demaille <akim@epita.fr>
11512 From now on, autoscan files must always map a macro name to a
11513 word: there is no `default' macro for autoscan.
11515 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11517 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11520 2002-09-28 Akim Demaille <akim@epita.fr>
11522 * bin/autoscan.in (%c_keywords): Remove.
11523 (&used): Keep only track of the words we might be interested in.
11524 (&output_kind): It is no longer needed to look for non active

11538 Thanks to Bill Moseley and Paul Eggert.
11539 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
11540 the tmpdir must be created.
11541 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
11542 dir be in the build tree, instead of $TMPDIR.

11546 * bin/autoscan.in: Improve the comments.
11547 (&parse_args): Drop obsolete undocumented options.

11555 Reported by Ralf Corsepius.
11556 * doc/autoconf.texi (autoreconf Invocation): Likewise.
11558 2002-09-26 Akim Demaille <akim@epita.fr>
11560 Single suffix rules and seperated dependencies are not portable.
11562 * doc/autoconf.texi (Installation Directory Variables): Update.
11563 (Limitations of Make): Some about `Single Suffix Rules and
11564 Separated Dependencies'.
11565 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11566 (ifnames, autoscan, autom4te): Un-factor into several rules.
11568 2002-09-25 Paul Eggert <eggert@twinsun.com>
11570 * BUGS (Interoperability bugs): New section. Mention libtool
11571 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
11573 2002-09-24 Paul Eggert <eggert@twinsun.com>
11575 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
11576 make handles suffix-rules differently from GNU make.
11578 * bin/Makefile.am (SUFFIXES, .in): Remove.
11579 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
11580 Move the body of the old .in rule here.
11582 2002-09-16 Akim Demaille <akim@epita.fr>
11584 i960 compilers create `b.out' files by default.
11585 Reported by Ralf Corsepius.
11587 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
11588 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
11590 2002-09-13 Paul Eggert <eggert@twinsun.com>
11592 * doc/autoconf.texi (Particular Headers): Remove obsolete
11593 reference to `struct timezone' in the description of

11601 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
11602 * Makefile.am: Adjust.
11604 2002-09-13 Akim Demaille <akim@epita.fr>
11606 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
11607 reading config.log when the compiler is rejected.
11608 Suggested by Guido Draheim.
11610 2002-09-13 Akim Demaille <akim@epita.fr>
11612 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11613 (chdir_init) might hang when stat'ing mounted directories.
11614 Reported by Vance Shipley.
11616 2002-09-12 Akim Demaille <akim@epita.fr>
11618 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
11621 2002-09-12 Akim Demaille <akim@epita.fr>
11623 * doc/autoconf.texi (Defining Symbols): Present two different
11624 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
11625 difference between 1 argument calls, and 2-3 argument calls.
11627 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
11629 * doc/autoconf.texi: Review grammar and punctuation.
11631 2002-09-11 Paul Eggert <eggert@twinsun.com>
11633 * doc/autoconf.texi: Fix minor formatting, spelling, and
11635 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
11636 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
11639 2002-09-11 Akim Demaille <akim@epita.fr>
11641 * doc/autoconf.texi (Questions): Rename as...
11643 (Defining Directories): New.
11645 2002-09-09 Akim Demaille <akim@epita.fr>
11647 * doc/autoconf.texi (Making testsuite Scripts): Update.
11648 Suggested by Nishio Futoshi.
11650 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
11652 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
11653 plain `@' is wanted.
11655 2002-09-09 Akim Demaille <akim@epita.fr>
11657 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11658 `duplicates', since the algorithm was too naive and could keep
11659 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11660 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11661 Reported by Ralf Corsepius.
11662 * tests/torture.at (Configuring subdirectories): Exercise these
11665 2002-09-09 Akim Demaille <akim@epita.fr>
11667 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
11668 looking for a replacement file.
11669 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11670 directory is relative.
11671 * doc/autoconf.texi (Generic Functions): Clarify the replacement
11672 directory definition.
11673 Reported by Andreas Schwab and Jim Meyering.
11675 2002-09-06 Akim Demaille <akim@epita.fr>
11677 * doc/autoconf.texi (Setting Output Variables): Clarify what
11678 precious variables are.
11679 Suggested by Pontus Skoeld.
11681 2002-09-05 Akim Demaille <akim@epita.fr>
11683 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11684 (ifnames, autoscan, autom4te): Since we don't only depend on
11685 configure.ac variables (such as VERSION etc.), but also on prefix
11686 and so forth, depend on Makefile, not configure.ac.
11687 Reported by Alexandre Duret-Lutz.
11688 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11690 2002-09-05 Kevin Ryde <user42@zip.com.au>
11692 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11693 doesn't seem to be confined to ia64, just say "some versions".
11695 2002-09-04 Akim Demaille <akim@epita.fr>
11697 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11699 * Makefile.am (maintainer-clean-local): Remove.
11700 (MAINTAINERCLEANFILES): Remove COPYING.
11702 2002-09-03 Paul Eggert <eggert@twinsun.com>
11704 * doc/autoconf.texi (Configuration Commands): Remove obsolete
11705 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
11708 2002-09-03 Akim Demaille <akim@epita.fr>
11710 * configure.ac: Bump to 2.53d.
11711 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11712 as of today, on Automake's team suggestion.
11714 2002-09-03 Akim Demaille <akim@epita.fr>
11718 2002-09-02 Akim Demaille <akim@epita.fr>
11720 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
11722 * configure.ac: Disable SITE_MACRO_DIR.
11724 2002-09-02 Jim Meyering <meyering@lucent.com>
11726 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11727 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11728 Also, tweak grammar: s/make sure to/be sure to/.
11730 2002-09-02 Paul Eggert <eggert@twinsun.com>
11732 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11733 directory names are generally preferable to physical names.
11735 2002-09-02 Akim Demaille <akim@epita.fr>
11737 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11738 Reported by Raja R. Harinath.
11739 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11740 * bin/autoupdate.in: Use error instead of die.
11742 2002-09-01 Paul Eggert <eggert@twinsun.com>
11744 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11745 ordinary shell concatenation rather than echo+tr+sed command that
11746 runs afoul of a long-line-related sed bug in Solaris 8.
11748 * bin/autoheader.in (parse_args): --warning -> --warnings.
11750 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11751 stdout, as traditional "ls" does.
11752 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11753 _AC_COMPILER_EXEEXT_O): Likewise.
11754 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11756 * bin/autoconf.as: Add --prepend-include option. This patch was
11757 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11758 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11760 * bin/autoconf.in, configure: Regenerate.
11762 * doc/autoconf.texi (Special Shell Variables): Mention
11763 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11765 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11766 MAILPATH and set PS1, PS2, PS4 to default values, to work
11767 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11768 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11769 the Autoconf documentation specifies; fall back to "unset" only if
11770 this fails. Use a shell for-loop for this rather than an m4 loop,
11771 to shorten the output script.
11773 2002-08-30 Paul Eggert <eggert@twinsun.com>
11775 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11776 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11777 for the CDPATH problem. Document PWD.
11778 (Limitations of Builtins): Document the problem that "cd $foo" and
11779 "ls $foo" may refer to different directories in shells conforming
11780 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11781 example, since the old example is now out of date.
11783 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11784 FOO" and "ls FOO" talk about different directories; this catches
11785 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11788 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11789 of rolling our own unset.
11790 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
11791 in practice we needn't worry about CDPATH if unset doesn't work.
11793 * Makefile.in, aclocal.m4, bin/Makefile.in,
11794 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
11795 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
11796 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
11797 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
11798 tests/Makefile.in: Regenerate with Automake 1.6.3.
11800 * config/config.guess, config/config.sub, config/mkinstalldirs:
11803 * configure: Regenerate with self.
11805 2002-08-30 Kevin Ryde <user42@zip.com.au>
11807 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
11810 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
11812 * bin/autom4te.in (Request::load): Correctly test for "do" read
11815 2002-08-29 Akim Demaille <akim@epita.fr>
11817 * lib/Autom4te/General.pm (&xqx): New.
11818 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11819 hand, which is not portable.
11821 * bin/autom4te.in: Use them.
11822 Use &error instead of die.
11823 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11826 2002-08-17 Paul Eggert <eggert@twinsun.com>
11828 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
11829 default list of compilers to try, since it was long ago superseded
11830 by the ksh fc builtin. Suggested by Steven G. Johnson.
11832 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
11834 * doc/autoconf.texi (Invoking autom4te): End the option table,
11835 fixing a bug introduced by the previous patch.
11836 (Limitations of Make): Add a 'target lookup' subentry in the
11837 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
11839 2002-07-29 Mark D. Roth <roth@feep.net>
11841 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
11842 options and use $AUTOM4TE_PATH.
11843 * doc/autoconf.texi: Remove documentation of autom4te
11844 --include-envvar and --site-macro-subdir options and document
11845 use of $AUTOM4TE_PATH.
11846 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
11847 arguments from each language section.
11849 2002-07-29 Paul Eggert <eggert@twinsun.com>
11851 * doc/install.texi: Include copyright symbol in copyright notice.
11853 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
11855 (AM_MAKEINFOFLAGS): New macro.
11856 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
11857 * Makefile.am (INSTALL): Use the new macros.
11858 Use -o rather than --output, since "missing" does not grok --output.
11860 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11862 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
11863 comments do not always work. Never trust the exit status of
11866 2002-07-24 Kevin Ryde <user42@zip.com.au>
11868 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
11869 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
11871 2002-07-23 Paul Eggert <eggert@twinsun.com>
11873 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
11874 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
11875 apparently treats PATH="nonexistent" as if it contained ".".
11876 Bug reported by Stefan `Sec' Zehl.
11878 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11880 * doc/autoconf.texi (Limitations of Make): Mention the special
11881 handling of the obj/ directory by BSD make.
11883 2002-07-20 Kevin Ryde <user42@zip.com.au>

11915 Alexandre Duret-Lutz <duret_g@epita.fr>
11917 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install

11923 description of the tarname default.
11925 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
11927 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
11928 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
11929 latter was not run.
11931 2002-07-17 Akim Demaille <akim@epita.fr>
11933 * lib/Autom4te/General.pm (find_file): Browse the directories in
11934 the order they are given.

11940 * tests/Makefile.am, configure.ac: Adjust.
11942 2002-07-17 Mark D. Roth <roth@feep.net>
11944 * configure.ac: Add --enable-site-macro-dir option.
11945 * bin/Makefile.am: Expand @SITE_MACRO_DIR@.
11946 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
11947 --site-macro-subdir options.
11948 * bin/autoconf.in: Add --prepend-include option.
11949 * bin/autoheader.in: Add --prepend-include option.

11954 macro directory, remove note that include path directories are

12146 This improves on an earlier suggestion by H. Peter Anvin.
12148 2002-05-16 Paul Eggert <eggert@twinsun.com>
12150 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12151 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12152 Both macros now accept an optional source-dir arg.
12153 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12155 * NEWS: Document this.
12156 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12158 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12159 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12160 not for GNU extensions; this undoes part of the 2000-11-03 change,
12161 reverting to 2.13-compatible behavior.

12169 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12170 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12171 and it causes a 'test' syntax error if it fails.
12172 Bug reported by Stephen Gildea.
12174 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12175 If prototypes are supported, use them to check this at compile-time,
12176 instead of trying to check it at run-time. If we must do a run-time
12177 check, assume that setvbuf is standard when cross-compiling, as
12178 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12179 Bug reported by Paul D. Smith.
12181 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12182 argument specifying location of getloadavg.c. This removes a
12183 FIXME. This idea was taken from Jim Meyering's implementation in
12185 * doc/autoconf.texi (Particular Functions): Document this.
12186 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12187 that's what the code does; this fixes a bug reported by

12192 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12193 autopoint instead of gettextize.
12194 ($uses_alocal): Rename as...
12195 ($uses_aclocal): this.
12196 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12197 Suggested by Bruno Haible.
12199 2002-05-03 Akim Demaille <akim@epita.fr>
12201 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12203 2002-04-29 Paul Eggert <eggert@twinsun.com>
12205 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12206 files to be 1 second older; just set them to be the same time.
12207 Also, sleep 1 second after the first aclocal, to work around
12208 problems with sub-second time stamps on the input files.
12210 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12212 * doc/autoconf.texi: Mention "set -e -x" lossage

12219 From Christian Cornelssen.
12221 2002-04-29 Akim Demaille <akim@epita.fr>
12223 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12224 of lack of $LINENO support, then the test will compare the $LINENO
12225 in testsuite vs. the lineno in the test file. This is wrong, of
12227 Be sure to protect it.
12228 Reported by Patrick Welche.
12230 2002-04-25 Akim Demaille <akim@epita.fr>
12232 * doc/autoconf.texi (Obsolete Macros): Typo.
12233 Reported by Vladimir Volovich.
12235 2002-04-25 Akim Demaille <akim@epita.fr>
12237 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12238 than some of the input files, hence, on the second run of aclocal,
12239 if some of its input are younger, make them older.
12240 Suggested by Paul Eggert.
12242 2002-04-25 Akim Demaille <akim@epita.fr>
12244 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

12250 and ac_subst_vars be sh variables containing the list of
12251 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12253 (_AC_INIT_PREPARE): Use them to log them.
12254 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12255 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12256 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12257 _AC_SUBST_FILES and _AC_SUBST_VARS.
12258 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12260 2002-04-24 Akim Demaille <akim@epita.fr>
12262 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12263 autoheader, so that automake does not complain about a missing
12264 config.h.in that was to be created.
12266 2002-04-23 Akim Demaille <akim@epita.fr>

12452 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
12453 (_AC_COMPILER_OBJEXT): Use them.
12454 Fixes Debian #138666.
12456 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
12458 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12460 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12461 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12462 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
12463 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
12464 (AC_C_CONST): Same.

12476 2002-03-28 Kevin Ryde <user42@zip.com.au>
12478 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12479 to avoid versions of HP C which don't allow that.
12481 2002-03-27 Paul Eggert <eggert@twinsun.com>
12483 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

12495 2002-03-25 Paul Eggert <eggert@twinsun.com>
12497 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12498 as POSIX requires, as it doesn't work with Zsh.
12499 * doc/autoconf.texi (Assignments): Document the problem.
12501 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12503 * doc/autoconf.texi (Limitations of Make): Mention more issue
12504 about VPATH, overriding of macros in sub-makes, and handling of

12509 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12510 problem with here-document buffer boundaries.
12512 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12513 when reinvoking the shell, to work around problems with installers
12514 who put strange things like "cd" commands in their environments.

12539 (Limitations of Usual Tools): Add mkdir section.
12541 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12542 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12543 back on AS_DIRNAME to compute prefixes otherwise; this is
12544 roughly what mkinstalldirs does. That way, we need not have
12545 our own filename disassembler. The old disassembler did not
12546 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12548 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12549 Create at_test_all by a series of assignments,
12550 not by a single assignment of a long string. The latter causes ksh
12551 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12552 presumably because of a buffer overrun.
12554 2002-03-14 Paul Eggert <eggert@twinsun.com>
12556 * lib/autotest/general.m4 (at_times_skip):
12557 Renamed from at_times. Now a boolean.
12558 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12559 says 'times: not found'.
12561 2002-03-14 Akim Demaille <akim@epita.fr>
12563 * bin/autoreconf.in (&study_gettextize): New.
12564 (&autoreconf): Handle newest gettextize.

12588 2002-03-11 Andreas Schwab <schwab@suse.de>

12591 does not do it if --with-lispdir is given.

12602 2002-03-08 Akim Demaille <akim@epita.fr>
12604 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12606 2002-03-08 Akim Demaille <akim@epita.fr>
12608 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12609 aliases the actual variables, and modifications of the former
12612 2002-03-08 Akim Demaille <akim@epita.fr>
12614 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12615 because of C-c: have m4 output in tmp files, then mv them.
12617 2002-03-08 Akim Demaille <akim@epita.fr>

12638 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
12639 * lib/autoconf/general.m4 (AC_INIT): More informative error
12640 message for LIBOBJ.
12642 2002-03-04 Akim Demaille <akim@epita.fr>

12647 2002-03-04 Akim Demaille <akim@epita.fr>
12649 * doc/autoconf.texi (Transforming Names): Equality between target
12650 and host is irrelevant.
12651 (Specifying Names, Canonicalizing): Remove all references to the
12652 backward compatibility hooks. Rather, collect them all into...
12653 (Hosts and Cross-Compilation): this new section.
12654 * doc/install.texi (System Type): Ditto.
12655 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12656 that `--host' implies cross-compilation.
12658 2002-03-04 Akim Demaille <akim@epita.fr>
12660 * doc/autoconf.texi (Evaluation Macros): New.
12661 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12663 (_m4_foreach): Define the variant with immediate evaluation so
12664 that it contains exactly the items, not an expression which
12665 evaluation is the current item.
12666 (m4_re_string, m4_re_word): Don't over quote them.
12668 2002-03-04 Akim Demaille <akim@epita.fr>
12670 Instead of having stacking `shift's evaluated at the end, let
12671 `foreach' loops immediately evaluate them.
12673 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12674 $*. This is the n-th time I change my mind, but hopefully this is
12677 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12679 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12680 it was only a hack for m4_text_wrap.
12681 (m4_car2): Remove, replaced by...
12683 (_m4_foreach): Adjust.
12684 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12685 m4_bpatsubst for clarification.

12776 2002-02-05 Akim Demaille <akim@epita.fr>
12778 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

12801 optional are the sum of the previous files on the command line'.
12802 Also, pass `--reload-state=' on them, so...
12803 (handle_m4): don't.

12805 (M4sh): Rely on M4sugar.

12843 2002-01-28 Akim Demaille <akim@epita.fr>
12845 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12846 AUTOTEST_PATH *after* it was set.
12847 Don't put `.' in the PATH: the user should be precise and `./' if
12848 needed. In addition, given that the test suite does some `cd', if
12849 `.' is in the path, the `tested programs' sections will report
12850 programs found in the test suite's directory, while during the
12851 tests (performed in their own directory), these programs are no
12852 longer visible. In other words, the results is confusing and

12929 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
12930 and PACKAGE_BUGREPORT from here...
12931 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
12933 (_AC_INIT_PREPARE): AC_DEFINE these symbols.

12956 * doc/autoconf.texi (New Macros): Tweak wording.
12958 2001-12-14 Akim Demaille <akim@epita.fr>
12960 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
12961 trailing files, don't apply `-rf' to files which might not be
12962 created by configure (core, core.*, and *.core), but just `rm -f'.
12963 Suggested by Jonathan Kamens.
12965 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
12967 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
12969 2001-12-14 Akim Demaille <akim@epita.fr>
12971 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
12973 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
12975 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
12976 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
12977 abs_srcdir, top_srcpath to abs_top_srcdir.
12978 (_AC_OUTPUT_FILES): Adjust.
12979 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
12980 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
12981 * tests/wrappl.in, tests/wrapsh.in: Adjust.
12983 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
12985 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
12986 C/Fortran linking on HP/UX, by extracting the Fortran library
12987 search path from the LPATH line in the $F77 -v output.
12989 2001-12-12 Kevin Ryde <user42@zip.com.au>
12991 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
12992 forbidden file descriptors table.
12994 2001-11-26 Akim Demaille <akim@epita.fr>
12996 * bin/autoscan.in (%c_keywords): Build it at top level.
12997 Map to 1 in order to simplify its uses.
12999 2001-11-26 Akim Demaille <akim@epita.fr>
13001 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13002 Remove $filepath, useless.
13003 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13004 variables, they are really part of the tokens.
13005 Split the input line on spaces and then look for tokens.
13006 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13007 because of `lex$U.$(OBJEXT)'.
13008 (&scan_files): Use "@list" instead of join.
13009 * doc/Makefile.am (CLEANFILES): Add *.fns.
13011 2001-11-26 Akim Demaille <akim@epita.fr>
13013 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13014 Remove, replaced by...
13015 * tests/wrappl.in: Be common for all the Perl executables.
13016 In particular autoscan and autoheader want -I.
13017 * configure.ac: Adjust.
13018 * lib/autoscan/headers: errno.h is portable.
13020 2001-11-26 Akim Demaille <akim@epita.fr>
13022 * bin/autoscan.in (used): New.
13025 2001-11-26 Akim Demaille <akim@epita.fr>
13027 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13029 (&scan_sh_file): Remove a duplicate pattern.
13030 (&check_configure_ac): Use long options.
13031 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13033 2001-11-26 Akim Demaille <akim@epita.fr>
13035 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13036 Before, having a line containing the opening of a multi line
13037 comment made the whole line be ignored.
13039 2001-11-26 Akim Demaille <akim@epita.fr>
13041 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13042 (testsuite Scripts): Be one of its subsection.
13043 (Autotest Logs): New.
13045 2001-11-26 Akim Demaille <akim@epita.fr>
13047 Test groups are now run two directories deeper.
13049 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13050 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13052 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13053 top_srcdir, builddir and top_builddir.
13054 Use `at_*dir' relatively to the directory containing the
13055 suite, use `*dir' when relatively to the current group dir.
13057 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13059 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13060 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13061 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13064 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13066 * doc/autoconf.texi (Using System Type): Add an example of `case
13067 $host' usage so people quit using `case $target' everywhere.
13069 2001-11-22 Akim Demaille <akim@epita.fr>
13071 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13072 spotted by Jim Meyering.
13074 2001-11-16 Paul Eggert <eggert@twinsun.com>
13076 This patch implements a `long double' suggestion by Oliver Kiddle.
13078 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13079 static, to catch errors if the value isn't known at compile-time
13080 and the compiler supports dynamic arrays. Change its name from
13081 `_array_' to `test_array' to avoid potential name clashes.
13082 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13083 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13084 better than double. Catch a bug in GCC 2.95.2 x86.
13085 * doc/autoconf.texi (C Compiler): Document the above.
13088 2001-11-13 Akim Demaille <akim@epita.fr>
13090 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13092 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13094 2001-11-13 Akim Demaille <akim@epita.fr>
13096 * lib/autotest/general.m4 (AT_INIT): After having run the test
13097 group, go back to the initial directory, not to at_suite_dir.
13099 2001-11-13 Akim Demaille <akim@epita.fr>
13101 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13102 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13103 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13105 (AT_CHECK_CONFIGURE): Use absolute paths.
13106 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13107 The problem is still the old one: there is no means in M4 (that I
13108 know about) to create a defining macro, because there is no means
13109 to create `$1' etc., therefore, the defining macro ``swallows''
13110 all the arguments meant to the defined macro.
13112 2001-11-13 Akim Demaille <akim@epita.fr>
13114 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13115 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13117 * tests/aclocal.m4: Remove, as it is no longer used.
13119 2001-11-13 Akim Demaille <akim@epita.fr>
13121 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13122 variable names when referring to a single test group, or to
13123 `suite' when referring to the whole test suite.
13124 `at_last_test' is removed: m4 compute at_format itself.
13125 (at_stdout, at_stder1, at_stderr): New variables.
13126 (AT_CHECK): Use them.
13128 2001-11-13 Akim Demaille <akim@epita.fr>
13130 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13132 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13133 Do it as soon as a test fails, don't wait till the end of the test
13135 Don't remove $as_me.[0-9]*, since these files no longer exist.
13137 2001-11-13 Akim Demaille <akim@epita.fr>
13139 * tests/tools.at: Use absolute paths, since we are no longer run
13142 2001-11-13 Akim Demaille <akim@epita.fr>
13144 Now that tests are running in their own private dir, there is no
13145 need to list the files to remove at the end of tests groups.
13147 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13148 (AT_data_files, at_data_files): Remove.
13149 (AT_CLEANUP, AT_DATA): Simplify.
13151 Remove the group dir if !debug && !failed.
13152 * tests/atspecific.m4: Adjust.
13154 2001-11-13 Akim Demaille <akim@epita.fr>
13156 Start a new layout for Autotest: `testsuite' creates
13157 `testsuite.dir' in which the at-check-line etc. files are to be
13158 found, and `testsuite.dir/003' where the test group 3 is run.
13160 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13161 at_check_line_file, at_format, at_test_normalized, at_group_dir
13163 Create the directories.
13164 Use absolute paths for at- files.
13165 (AT_CHECK): Adjust.
13167 2001-11-11 Michael Matz <matz@kde.org>
13169 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13171 (m4_car): Properly quote arguments.
13173 2001-11-13 Akim Demaille <akim@epita.fr>
13175 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13176 with stricter rules on LIBOBJS.
13178 2001-11-12 Paul Eggert <eggert@twinsun.com>
13180 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13181 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13184 2001-11-12 Akim Demaille <akim@epita.fr>
13186 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13188 2001-11-12 Akim Demaille <akim@epita.fr>
13190 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13191 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13192 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13193 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13194 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13195 specify to what the macro should be defined (typically to 1).
13197 2001-11-12 Akim Demaille <akim@epita.fr>
13199 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13202 2001-11-12 Akim Demaille <akim@epita.fr>
13204 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13205 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13206 definition used by Automake where LEX is +/- "${missing} lex" and
13207 `missing' itself contains variables.
13209 2001-11-12 Akim Demaille <akim@epita.fr>
13211 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13212 Now that M4sh pushes BODY, the comments were output at the end of
13215 2001-11-08 Akim Demaille <akim@epita.fr>
13217 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13218 that we can trace macros from aclocal.m4.
13219 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13220 obsoleted, and redirect to the former anyway.
13221 Reported by Ralf Corsepius.
13223 2001-11-08 Akim Demaille <akim@epita.fr>
13225 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13226 processed only if present.
13227 * tests/torture.at (Configuring subdirectories): Use autoreconf
13228 instead of successive calls to autoconf.
13229 Add a nonexistent subdirectory to exercise the patch above.
13230 Reported by Ralf Corsepius.
13232 2001-11-08 Kevin Ryde <user42@zip.com.au>
13234 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13235 doesn't accept .S files.
13237 2001-11-07 Akim Demaille <akim@epita.fr>
13239 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
13240 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
13241 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13242 * bin/autom4te.in (warn_forbidden): New.
13243 (handle_output): Use it.
13244 Read m4_pattern_forbid with messages.
13246 2001-11-05 Akim Demaille <akim@epita.fr>
13248 * bin/autom4te.in (--normalize): Remove.
13249 * lib/autom4te.in: Adjust.
13251 2001-11-05 Akim Demaille <akim@epita.fr>
13253 * tests/Makefile.am (testsuite): Rename this target as...
13254 ($(TESTSUITE)): this.
13257 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13259 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13260 the --prefix option, also remove it's argument.
13262 2001-11-05 Akim Demaille <akim@epita.fr>
13264 * doc/autoconf.texi (testsuite Invocation): Update.
13265 (Writing testsuite.at): Update.
13267 2001-11-03 Akim Demaille <akim@epita.fr>
13269 * doc/autoconf.texi: s/@code/@command/ where appropriate.
13271 2001-11-03 Akim Demaille <akim@epita.fr>
13273 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13274 (&file_name_is_absolute): New, wrappers around routines from
13276 Use and export them.
13277 (&find_configure_ac): Optionally take a directory where to look at.
13278 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13280 Default @ARGV to `.', not find_configure_ac.
13281 (&autoreconf): Argument is a directory.
13282 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13283 * doc/autoconf.texi (autoreconf Invocation): Update.
13285 2001-11-03 Akim Demaille <akim@epita.fr>
13287 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13288 (@export_forward_subs): New.
13289 Add basename, dirname, and fileparse.
13291 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13292 Don't look for aclocal flags if we already know aclocal is not
13294 Move aclocal.m4t only if it exists.
13295 Reported by Ezra Peisach.
13297 2001-11-03 Akim Demaille <akim@epita.fr>
13299 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13300 passed on command line, defaulting to ./configure.ac if present.
13301 (&maybe_autoreconf, File::Find): Remove, unused.
13302 (&autoreconf): If autoconf is not used, don't try to trace.
13304 2001-11-02 Akim Demaille <akim@epita.fr>
13306 * configure.ac: Bump to 2.52g.
13308 2001-11-02 Akim Demaille <akim@epita.fr>
13312 2001-11-02 Akim Demaille <akim@epita.fr>
13314 * config/config.guess, config/config.sub, doc/standards.texi:
13315 * config/lispdir.m4: Update from masters.
13316 * configure.ac: Bump to 2.52f.
13318 2001-11-02 Akim Demaille <akim@epita.fr>
13320 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13321 Don't run aclocal when aclocal.m4 is not from aclocal.
13323 Don't run libtoolize and gettextize if --install is not given.
13325 2001-11-01 Paul Eggert <eggert@twinsun.com>
13327 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13328 be invoked before _AS_LINENO_PREPARE.
13329 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13330 than character ranges.
13332 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13333 invoking AS_BASENAME. Set the locale variables to 'C' if
13334 possible, as POSIX requires this to get the traditional
13336 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13338 2001-10-31 Paul Eggert <eggert@twinsun.com>
13340 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13341 with {}, as that triggers a bug in Bash 2.05.
13343 (_AS_LINENO_PREPARE): Use Sed rather than
13344 Awk. Fix the sed prepass to work even if there are multiple
13345 instances of $LINENO on the same line. Do not substitute for
13346 other variables like $LINENOT. Do not check file dates; such a
13347 check is unreliable on sufficiently fast machines, and removing
13348 the check makes the code simpler and more reliable. Check for
13349 output and chmod failures.
13351 * doc/autoconf.texi (Special Shell Variables): Document
13354 2001-10-31 Akim Demaille <akim@epita.fr>
13356 * tests/Makefile.am (atconfig): Remove this target, Automake
13359 2001-10-31 Akim Demaille <akim@epita.fr>
13361 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13362 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13363 provided, while it is optional.
13364 * configure.ac: Adjust.
13366 2001-10-26 Paul Eggert <eggert@twinsun.com>
13368 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13369 lib/Autom4te/Struct.pm:
13370 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13373 * doc/autoconf.texi (Special Shell Variables): Document some
13374 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13376 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13377 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13378 eval $LINENO is not portable in practice.
13380 2001-10-24 Akim Demaille <akim@epita.fr>
13382 * lib/Autom4te/General.pm (backname): New.
13384 2001-10-24 Akim Demaille <akim@epita.fr>
13386 * m4/: Remove, merged into...
13389 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
13391 * doc/autoconf.texi (Shellology): Mention the problems with bash
13392 2.05's use of ANSI quoting in its `set' builtin.
13394 2001-10-22 Paul Eggert <eggert@twinsun.com>
13396 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13397 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13398 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13399 POSIX decided to standardize on the int flavor of strerror_r.
13400 Always do char* test, as there's no reason not to.
13401 Assign to a char* var, to catch strerror_r that returns int*.
13403 * doc/autoconf.texi (Particular Functions):
13404 Document the above changes. Also, document the fact that
13405 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13407 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13409 2001-10-20 Akim Demaille <akim@epita.fr>
13411 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
13412 the executable was missing from the log.
13414 2001-10-20 Akim Demaille <akim@epita.fr>
13416 * lib/Autom4te/General.pm (&update_file): If destination is
13417 unchanged, remove the source.
13418 (&up_to_date_p): Don't be verbose, be debug.
13419 * bin/autoreconf.in: No longer support --m4dir.
13420 (&autoreconf): Display the full path of the configure.ac we are
13422 Trace it only once.
13423 Be sure to honor --force with gettextize.
13424 Always run aclocal.
13425 * doc/autoconf.texi: Adjust.
13427 2001-10-20 Akim Demaille <akim@epita.fr>
13429 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13431 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13432 `intl' is already present, as it refuses unless --force.
13433 (&parse_args): Use -I, --include instead of the old Autoconf
13435 ($localdir, $autoconf_dir): Remove.
13437 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13439 2001-10-19 Jens Petersen <petersen@redhat.com>
13441 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
13442 * doc/autoconf.texi (Particular Programs): Likewise.
13444 2001-10-19 Akim Demaille <akim@epita.fr>

13909 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
13910 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
13912 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13914 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
13915 * bin/autoupdate.in: Ditto.
13916 * bin/autoheader.in: Reworded a few comments.
13917 * bin/autoconf.in: Reworded help text for a few options.
13918 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,

13921 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13923 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
13924 already have $file). Set output files to binary mode (helps avoid
13925 CR issues on DOSish systems).
13927 2001-09-19 Akim Demaille <akim@epita.fr>
13929 * lib/autotest/general.m4: Englishoes.
13930 From Tim Van Holder and Alexey Mahotkin.
13932 2001-09-18 Paul Eggert <eggert@twinsun.com>
13934 * doc/autoconf.texi (Common Shell Constructs): New node,
13935 documenting AS_DIRNAME.
13936 (Limitations of Usual Tools): Refer to it when discussing dirname.
13937 Also, update discussion of POSIX standard to reflect latest draft.
13939 * lib/autoconf/c.m4:
13940 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
13942 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13943 Do not pass a first argument with leading '-'
13944 to expr, by parenthesizing initial integers that might be negative.
13946 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
13947 now merely checks whether it is an error to pass an argument
13950 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
13951 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
13952 whether it is a (compile-time) error to pass an argument to
13953 getpgrp. This simpler test supports the revised documentation,
13954 and is all that AC_FUNC_GETPGRP's users really need.
13956 2001-09-18 Akim Demaille <akim@epita.fr>
13958 * doc/autoconf.texi (Limitations of Make) <$<>: New.

13966 2001-09-18 Paul Wagland <paul@wagland.net>
13968 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
13970 Add test for AS_BASENAME.
13971 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
13972 added test. It now correctly handles /1/2/3/, returning '3' not ''.
13973 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
13974 * tests/base.at: Fixed the expected responses. The old ones were
13976 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
13977 the documentation claims it should (and how it behaved in 2.13).
13979 2001-09-18 Akim Demaille <akim@epita.fr>
13981 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
13982 the AC_CONFIG_COMMANDS invocation.
13983 This also solves the name clash problems.
13984 Don't set the package's ID.
13985 * lib/m4sugar/Makefile.am (version.m4): Revamp.
13986 No longer to be shipped.
13987 (version.in): Remove.

13989 * lib/autoconf/status.m4: Adjust.
13990 Use `m4_PACKAGE_STRING'.
13991 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
13992 the only optional argument is the name of the test suite.
13993 Expect `package.m4' to define the package signature.
13994 * lib/autom4te.in (Autotest): Add `package.m4?'.
13995 * tests/Makefile.am (package.m4): New.
13996 * tests/suite.at: ifnames is a victim.

14001 AC_LIBSOURCE, AC_CONFIG_FILES.
14002 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14003 program version string doesn't match the package's.
14004 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

14009 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14010 Allow expression to return any value that can fit into unsigned long
14011 (not int, as before). Check for output errors.

14015 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14016 Always include <stdio.h> and <stdlib.h>. Evaluate
14017 the expression in an extra function before these includes. Call
14018 fprintf "%d" only after ensuring the argument is of type 'int'.
14019 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14021 2001-09-17 Paul Eggert <eggert@twinsun.com>
14023 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14024 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14025 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14026 when they don't exist.
14028 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14029 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14032 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14033 version with the version used by fileutils 4.1, except use
14034 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14037 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14039 2001-09-13 Akim Demaille <akim@epita.fr>

14079 * lib/autotest/general.m4 (AT_INIT): Create and remove
14080 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14081 test suites can cohabit.

14085 * tests/mktests.sh: Don't output banners for empty test files.

14191 2001-09-05 Akim Demaille <akim@epita.fr>
14193 Be ready to handle filenames as stupid as `dnl.at', for if even
14194 the maintainer is dumb enough to do that...
14196 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14197 excellence in M4 quotation: consider `__file__' is active.

14374 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

14876 2001-08-15 Akim Demaille <akim@epita.fr>

14960 magic values from an object file when cross-compiling.
14961 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
14963 2001-08-10 Akim Demaille <akim@epita.fr>
14965 * bin/autom4te.in (&handle_output): Don't use `grep' with side
14967 Suggested by Russ Allbery.
14969 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
14971 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
14972 current $prefix to the sub-configures.
14974 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
14976 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
14977 extension (needed on BeOS). Reported by Guido van Rossum.
14979 2001-08-09 Akim Demaille <akim@epita.fr>
14981 * bin/autom4te.in ($icache): Load it only if older than autom4te.
14983 2001-08-07 Akim Demaille <akim@epita.fr>
14985 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
14987 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
14988 No need to remove the files before and after the each test, before
14989 each test and at the end of the suite is enough.
14990 Display only the children `times', not the shell's.
14991 If the test failed or was skipped, at-times is not available.
14993 2001-08-07 Akim Demaille <akim@epita.fr>
14995 Always produce testsuite.log, including when there are no
14996 failures. This helps getting information on skipped tests, and
14997 duration of the tests. Err, implement the latter btw.
14999 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15000 Dump information on the first run of each test.
15001 (AT_CLEANUP): Create `at-times' containing the duration of the
15004 2001-08-07 Akim Demaille <akim@epita.fr>
15006 The use of `dumpstat' revealed that `len' was used although it
15007 should not. m4_text_wrap was using it, but in the Autoconf world
15008 where it is legal. Hence (i) test M4sh in its own world, not
15009 Autoconf's, and (ii), ahem, fix the bug :)
15011 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15012 does not like `' instead of [].
15013 (AT_INIT): Forbid `^_?AT_'.
15014 And don't output such tokens.
15015 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15016 `script.as', and `autom4te.cache'.
15017 Remove `empty' and `macro' which are no longer used.
15018 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15019 * tests/m4sugar.at: Use it.
15020 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15022 2001-08-07 Akim Demaille <akim@epita.fr>
15024 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15026 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15028 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15030 2001-08-04 Akim Demaille <akim@epita.fr>
15032 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15033 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15035 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15036 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15037 (AC_F77_MAIN): Likewise.
15039 2001-08-04 Akim Demaille <akim@epita.fr>
15041 Don't rely on M4sugar outputting the patterns in files, since we
15042 might process the output _without_ running m4, hence without these
15045 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15046 * bin/autom4te.in (@Request::includes): Remove, unused.
15047 (@Request::source): Rename as...
15048 (@Request::input): this.
15049 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15050 (&handle_output): Fetch the patterns from the traces.
15051 `$forbidden' and `$allowed' are constant: use m//o.
15052 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15053 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15055 2001-08-04 Akim Demaille <akim@epita.fr>
15057 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15058 autoconf', i.e., in addition to caching traces, cache the output.
15060 * bin/autom4te.in (Request::cache): Rename as...
15061 (Request::id): this.
15062 ($cache, $icache, $tcache, $ocache): New.
15063 (&handle_m4): Save M4 output in the cache instead of $tmp.
15064 (&handle_output): Adjust.
15065 (&up_to_date_p): Check that the output cache is up to date too.
15066 (top level): Run `&handle_m4' iff force or the cache is invalid.
15067 Run `&handle_output' if the output cache is more recent.
15069 2001-08-04 Akim Demaille <akim@epita.fr>
15071 * bin/autom4te.in ($force): New.
15072 (&parse_args, &print_usage): -f, --force is a new option.
15073 (&handle_output): CPP directives might have spaces after `#'.
15074 (&parse_args): The first file only can be frozen.
15076 2001-08-04 Akim Demaille <akim@epita.fr>
15078 Don't let autom4te compute the `include' traces several times:
15079 first check that the trace cache file is up to date, and then
15080 compare its timestamp with that of the output.
15082 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15083 the preamble. Don't require 5.005 as Autom4te::General does it,
15084 and better yet (use `use', not `require'!).
15085 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15086 Class::Struct as Autom4te::Struct.
15087 * lib/Autom4te/General.pm (File::stat): Use it.
15088 (&mtime): New, export it.
15089 * bin/autom4te.in: Use it.
15090 Declare `$req' is invalid if it is outdated.
15091 Don't declare it valid before saving it if something went wrong.
15093 2001-08-04 Akim Demaille <akim@epita.fr>

15096 must be proposed to the users.
15098 * bin/autom4te.in (@required_trace): Remove.
15100 (&parse_args, &print_usage): -p, --preselect is a new option.
15101 (&up_to_date_p): Adjust.

15106 * tests/tools.at (autoconf --trace: user macros): Check traces on
15107 macros invoked without arguments, and macros invoked with multiple

15115 2001-08-03 Akim Demaille <akim@epita.fr>
15117 * bin/autoconf.in ($@): Work around the usual sh bug.
15120 2001-08-03 Akim Demaille <akim@epita.fr>
15122 Clean up the handling of the M4 builtins tracing exception.
15124 * bin/autom4te.in (Request::request): Don't complete M4 builtins
15126 (@m4_builtins): Rename as...
15127 (@m4_builtin): this.
15128 (%m4_builtin_alternate_name): New.
15129 (&parse_args): Complete the trace requests with alternate names.

15135 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
15136 m4_if, and m4_wrap.
15138 2001-08-03 Akim Demaille <akim@epita.fr>
15140 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
15141 (m4_divert_pop): Dump the whole diversion stack when a diversion
15143 * bin/autom4te.in (&handle_output): Remember of the first
15144 occurrence of a possibly undefined macro, not the last.
15145 Complain about the possibly undefined macros in the same order as
15146 the appear in the output.
15147 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
15148 * tests/tools.at (autoconf: forbidden tokens, basic)
15149 (autoconf: forbidden tokens, exceptions): No longer sort
15150 autoconf's stderr, as it is now deterministic.
15151 Check that `dnl' is caught.
15153 2001-08-01 Akim Demaille <akim@epita.fr>
15155 * configure.ac: Bump to 2.52c.

15172 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
15173 `END', as `Autom4te::General::END' will be triggered.
15174 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
15175 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
15176 system to run `mv', `rm', and `cmp'.

15180 * lib/Autom4te/General.pm (&unique): New.
