1006 * lib/autotest/general.m4 (AT_INIT) <PREPARE_TESTS>: Use fewer
1007 forks when sanitizing PATH. Always output machine information,
1008 not just when atconfig was located.
1010 Add 'testsuite -C dir'.
1011 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
1012 detection...
1013 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1014 argument.
1015 <DEFAULTS>: Delay computation of variables based on $at_dir...
1016 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
1017 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
1018 <PARSE_ARGS>: Parse new option.
1019 <HELP_TUNING>: Document it.
1020 * tests/autotest.at (Choosing where testsuite is run): New test
1021 for this feature.
1022 (Keywords and ranges): Add test for missing -k argument.
1023 * NEWS: Document this.
1024 * doc/autoconf.texi (testsuite Invocation): Likewise.
1026 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1028 * build-aux/config.guess, build-aux/config.sub,
1029 build-aux/texinfo.tex: Sync from gnulib.
1030 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
1031 Likewise.
1033 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1035 * doc/autoconf.texi (Particular Programs): Do not mention the
1036 Autoconf version in which the AC_PROG_INSTALL change was done.
1037 Suggested by Paul Eggert.
1039 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1041 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1042 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1043 mode, we change to the source directory, also set $ac_pwd so we
1044 do not go back to the build tree for the next config subdir.
1045 * tests/torture.at (Deep Package): Extend test to contain two
1046 config subdirs on the top level.
1048 Fix parallel `maintainer-check'.
1049 * Makefile.am (maintainer-check-tests): Depend on `all'.
1050 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
1051 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
1052 Likewise.
1053 (maintainer-check): Serialize the testsuite runs.
1055 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'
1056 in feature string for --enable/--with. Convert to underscore
1057 for variable name.
1059 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Require that
1060 `install -c file1 file2 dir' works.
1061 * doc/autoconf.texi (Particular Programs): Document this.
1062 * NEWS: Update.
1064 2008-01-21 Eric Blake <ebb9@byu.net>
1066 Improve documentation about default include directives.
1067 * doc/autoconf.texi (Generic Headers, Generic Declarations)
1068 (Generic Structures, Generic Types)
1069 (Generic Compiler Characteristics): Add links to
1070 AC_INCLUDES_DEFAULT.
1071 Reported by Reuben Thomas.
1073 2008-01-15 Eric Blake <ebb9@byu.net>
1075 * lib/m4sugar/m4sugar.m4 (m4_qlen): Use fewer macros.
1077 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1079 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
1080 check_SCRIPTS. Building the wrappers for `all' allows help2man
1081 to use them for the manpages.
1082 Report by Benoit Sigoure.
1084 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
1086 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1088 Fix some write failure cases in Autotest.
1089 * lib/autotest/general.m4 (AT_INIT): Do not exit successfully
1090 upon write failures for --help, --version, --list.
1091 Guard against write failures for intermediate created scripts.
1092 <at_func_create_debugging_script>: Do not make the debugging
1093 script executable if it is not complete.
1095 2007-12-12 Eric Blake <ebb9@byu.net>
1097 Fix thinko in earlier patch - m4_join isn't defined yet.
1098 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1099 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1100 (m4_require): Use m4_do, not m4_join.
1102 Fix some whitespace tests on cygwin.
1103 * tests/tools.at (autom4te and whitespace in file names): Restore
1104 font-lock. Create $TMPDIR before it might be used.
1106 Fix spurious testsuite failure with M4 1.4.11.
1107 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1109 Optimize AC_REQUIRE.
1110 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1111 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1112 (m4_require): Avoid extra macro calls.
1114 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1116 * tests/torture.at (srcdir): Fix quoting.
1118 Do not pass top_srcdir to configure scripts in testsuite.
1119 * tests/autotest.at (srcdir propagation): Copy install-sh to
1120 source tree.
1121 (my only test): Drop setting of `top_srcdir'.
1122 * tests/base.at (Input/Output): Likewise.
1123 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1124 config.guess, and config.sub to test source tree.
1125 Drop AC_CONFIG_AUX_DIR setting.
1126 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1127 * tests/torture.at (Substitute a 2000-byte string): Drop
1128 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1129 (Substitute a newline, datarootdir workaround): Likewise.
1130 (Define a newline): Adjust for linenumber changes in configure.ac.
1131 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
1133 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
1134 if `pwd` contains whitespace.
1136 Quote $abs_top_srcdir in tests.
1137 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1138 * tests/tools.at (Syntax of the shell scripts): Likewise.
1140 * tests/m4sh.at (LINENO): Quote $0.
1142 Fix testsuite program wrapper for whitespace in `pwd`.
1143 The problem here is that the usual mantra is that command
1144 variables can contain arguments, thus we cannot just escape
1145 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1146 $top_builddir/tests directory early in $PATH, so that the
1147 wrappers are found by their plain name.
1148 * tests/wrapper.as: Put $testdir early in $PATH.
1149 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1151 Proper config.status --file/--header and $srcdir escaping.
1152 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
1153 characters in $ac_file_inputs.
1154 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
1155 accordingly.
1156 * tests/torture.at (datarootdir workaround): Adjust.
1157 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
1159 Fix Autotest for whitespace in `pwd`.
1160 * lib/autotest/general.m4 (AT_INIT)
1161 <at_func_create_debugging_script, Driver Loop>:
1162 Quote $at_group_dir.
1163 * tests/autotest.at (whitespace in absolute testdir): New test.
1165 * lib/autom4te.in: Quote @datadir@.
1167 Proper file name escaping in Autoconf programs and Perl modules.
1168 This includes escaping of characters special to the shell
1169 as well as special to Perl, e.g., leading `<' or `>'.
1170 For example, when $file starts with `>', `open ">$file"'
1171 wrongly tries to append to a different file.
1172 * bin/autoconf.as: Fix quoting for autom4te options.
1173 * lib/Autom4te/General.pm (shell_quote): New function, taken
1174 from coreutils, written by Jim Meyering.
1175 (mktmpdir): Use it.
1176 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1177 and open_quote.
1178 * bin/autoreconf.in (parse_args): Likewise.
1179 * bin/autoscan.in (main): Likewise.
1180 * bin/autoupdate.in (main): Likewise.
1181 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1182 * bin/ifnames.in: Likewise, XFile usage fixes.
1183 * tests/tools.at (autom4te and whitespace in file names): Extend
1184 test. Test twice, with special characters allowed on w32, and the
1185 rest. Test leading and trailing whitespace, for `open_quote'.
1186 (autotools and whitespace in file names): New, analogous test.
1187 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1188 by Russ Allbery and Eric Blake.
1190 Sync from Automake.
1191 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1192 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1193 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1194 (update_file, contents): Use it.
1196 * Makefile.am (autom4te-update): Rewrite for git.
1198 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1200 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1202 Fix copyright years.
1203 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1204 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1206 2007-12-04 Eric Blake <ebb9@byu.net>
1208 Manually resync with gnulib, since 'make cvs-update' no longer works.
1209 * build-aux/config.guess: New upstream version.
1210 * build-aux/config.sub: Likewise.
1212 When using older automake, don't downgrade build-aux/texinfo.tex.
1213 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1214 * doc/Makefile.am (TEXINFO_TEX): Add.
1216 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1218 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1219 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1220 #undef as this runs afoul of our new way of creating config.h.
1221 Problem reported by Jim Meyering in
1222 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
1224 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1226 Fix autom4te for unusual characters in input file names.
1227 * bin/autom4te.in (files_to_options): Quote active characters
1228 for the shell.
1229 * tests/tools.at (autom4te and white space in file names):
1230 New test.
1232 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1233 Document that Tru64 awk always splits $0.
1235 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1237 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1238 `#AT_STOP_...' line at the end of each test.
1240 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1242 * lib/autotest/general.m4 (AT_INIT): For awk line number
1243 extraction script, ensure `$at_group' has a defined value
1244 even for the empty set, and properly quote its usage inside
1245 the awk script.
1247 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1249 * doc/autoconf.texi (Shell Functions): New chapter. Document
1250 IRIX sh $0 issue in functions, move content from ...
1251 (Portable Shell): ... here.
1252 (Shell Script Compiler): Note that shell functions are not
1253 totally unportable any more.
1255 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1256 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1258 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1259 extracting the line numbers of the last needed test.
1261 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1263 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1264 Fix quoting.
1266 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1268 Fix IRIX testsuite debugging failures: $0 in functions.
1269 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1270 Do not use $0 inside a function, as IRIX sh will set that to the
1271 function name rather than the script invocation name.
1273 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1274 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1276 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1277 to extract test scripts.
1278 (AT_INIT): Extract and cache test script line numbers.
1280 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1282 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1283 subsequent fixups; the awk -> here-document conversion trashes
1284 performance too much with AIX sh.
1286 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1288 * tests/local.at: Do not test m4, perl with AT_TESTED.
1290 Diagnose and guard against write errors dealing with config.status.
1291 The general idea is this: all write failures from `configure'
1292 writing `config.status' are indicated by $ac_write_error, which
1293 is only checked at the end. This is safe because config.status
1294 code is not executed before the file is complete. Other write
1295 failures, be they inside config.status, or in sub shell/awk
1296 scripts spawned from configure or config.status, typically need
1297 earlier checking, as their results are used right afterwards.
1298 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1299 before writing config.status, check afterwards.
1300 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1301 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1302 Set `ac_write_error' for write failures to config.status. Barf
1303 upon write failures to temporary files.
1304 Adjust note about closing and reopening the here-document.
1305 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1306 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1307 reopening the here-document.
1308 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1309 Ensure `ac_write_error' does not escape into config.status.
1310 Also, add a couple of code paths not yet exercised in the test
1311 suite: a config file with input from stdin, and a config header
1312 output to stdout.
1313 Suggestion for catching write errors by Bruno Haible.
1315 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1317 Avoid error with Tru64 awk and testsuite lines with many words.
1318 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1319 reads the testsuite, set the field separator to an unusual value,
1320 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1321 even splits the input if $i, i>0, was never accessed in the script.
1323 Revert 2007-10-17 change.
1324 * TODO: Multiline args in config files and headers mean something
1325 different and are not fixed, see
1326 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
1327 Report by Stepan Kasal.
1329 * doc/autoconf.texi (Generic Programs): Fix typo.
1331 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1333 AC_*_TOOL does not canonicalize the prefix
1334 * doc/autoconf.texi (Generic Programs): Do not say that
1335 the *_TOOL macros canonicalize, they simply use the `host_alias'.
1337 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1339 Diagnose write errors in config.status instantiations.
1340 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
1341 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
1342 on write errors.
1343 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1344 Extend test to also check for some write error failures, using...
1345 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
1346 Report by Bruno Haible.
1348 Indentation fixups.
1349 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix

1359 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
1360 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1376 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
1377 gnulib.

1381 * lib/autoconf/status.m4: Fix a couple of comment typos.
1383 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1385 2007-11-13 Jim Meyering <meyering@redhat.com>
1387 Clean up the rule to create "expr".
1388 * tests/Makefile.am (expr): Don't redirect directly to target.
1389 Redirect just once, not for each echo statement.
1390 Use $@, not literal "expr".
1392 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1394 Don't worry about preprocessor when testing long long.
1395 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1396 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1397 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1398 These no longer check for preprocessor flaws.
1399 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1400 Do not check for preprocessor flaws.
1402 2007-11-13 Jim Meyering <meyering@redhat.com>
1404 Adapt dependencies, now that a version change doesn't modify configure.ac
1405 * GNUmakefile: Remove "make clean" kludge.
1406 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1407 configure.ac.
1408 Don't redirect directly to target.
1409 Use $@, not literal "version.m4".
1411 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1413 * doc/autoconf.texi (Making testsuite Scripts): Document
1414 ":;{" shorthand as in previous patch.
1416 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1418 * doc/autoconf.texi (Limitations of Builtins): Document problem
1419 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1420 for the workaround.
1421 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1422 Use ":;{" shorthand.
1423 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1425 2007-11-12 Jim Meyering <meyering@redhat.com>
1427 Add more non-srcdir build support.

1429 Add -v option to autoreconf invocation.
1431 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1432 * GNUmakefile (dummy): Remove INSTALL.
1434 Remove racy commands to build scripts in bin/ and tests/.
1435 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1436 are guaranteed to be built, remove the rules that tried to build
1437 them. Before, with a parallel build, these rules could lead to
1438 two processes writing tests/wrapper.in concurrently.
1440 Build in man/ only *after* building in bin/ and tests/.
1441 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1442 in both bin/ and tests/.
1444 Accommodate non-srcdir build-from-checkout.
1445 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1446 Use git's --git-dir=$srcdir/.git option.
1447 Add quotes, in case tarball_version_file contains shell meta-characters.
1448 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1449 * configure.ac: Pass "." to git-version-gen.
1451 Avoid spurious test failures due to version skew.
1452 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

1479 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1481 Ignore configure --help* errors due to LINENO-impaired shells.
1482 * tests/torture.at (Configuring subdirectories, Deep Package):
1483 In the --help* tests in read-only trees, make `.' temporarily
1484 writable again for the `stderr' file, and ignore errors due to
1485 the attempt to write configure.lineno.
1486 Report by Patrick Welche.
1488 2007-11-10 Jim Meyering <meyering@redhat.com>
1490 Generate package.m4 in build-dir, not srcdir.
1491 * tests/Makefile.am (package.m4): Adjust target.
1492 Don't redirect directly to $@.
1493 (CLEANFILES): Add package.m4.
1494 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1495 in $(srcdir).
1496 When running $(AUTOTEST), search "." before searching $(srcdir).
1498 Avoid a race condition that would make parallel "distclean" fail.
1499 * tests/Makefile.am (distclean-generic): Replace the default,
1500 automake-provided rule with an identical one, but with an additional
1501 dependency on distclean-local. Simply adding the dependency would
1502 cause automake not to emit the rule at all.
1503 * BUGS: Building with -jN works, now.
1505 Distribute git-version-gen.
1506 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1507 since GNUmakefile is distributed, and requires it for dist* rules.
1509 Remove two more generated files from version control.
1510 * INSTALL: Remove generated file.
1511 * lib/autoscan/autoscan.list: Remove generated file.
1513 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1515 * GNUmakefile (PATH): Remove stray apostrophes; they become
1516 part of PATH, which isn't wanted here.
1518 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1520 New config files output variable `top_build_prefix'.
1521 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1522 `top_build_prefix'.
1523 * doc/autoconf.texi (Preset Output Variables): Document it.
1524 * NEWS: Update.
1525 Report by Bob Friesenhahn.
1527 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1528 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1529 function, to parametrize arithmetic with expr vs. the shell.
1530 Use it where possible.
1531 Suggestion by Benoit Sigoure.
1533 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1535 Adjust the documentation of autotest WRT atlocal.
1536 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1537 when using Automake, to write a rule to produce atlocal, since it's
1538 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1539 distributed, not atconfig.in.
1541 2007-11-04 Eric Blake <ebb9@byu.net>
1543 Update list information.
1544 * README: Mention new autoconf-commit list.

1551 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1553 * build-aux/.gitignore: Ignore mkinstalldirs.
1555 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1557 2007-11-03 Jim Meyering <meyering@redhat.com>
1559 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1560 * build-aux/git-version-gen: This syncs from coreutils.
1562 Adjust the build procedure so "make check" works reliably.
1563 * README-hacking: Include an extra step between "make" and
1564 "make check" to ensure that the latter passes.
1566 Use just-built tools, when possible.
1567 * GNUmakefile (PATH): Set and export here, ...
1568 (dummy): ... rather than here.
1570 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1571 and Andreas Schwab <schwab@suse.de>
1573 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
1574 exit status bug.
1576 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1578 * configure.ac (AC_PREREQ): Require version 2.60, for
1579 AC_PROG_SED, AC_PROG_GREP.
1581 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>

1588 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
1589 workaround.
1591 2007-11-03 Eric Blake <ebb9@byu.net>
1593 Support m4 1.4.5 in testsuite.
1594 * tests/torture.at (Define a newline): Exclude line numbers in
1595 error message.
1596 Reported by Ralf Wildenhues.
1598 2007-11-03 Jim Meyering <meyering@redhat.com>

1606 Suggestion from Ralf Wildenhues.
1608 2007-11-03 Eric Blake <ebb9@byu.net>
1610 Adjust version comparison to account for git snapshot numbers.
1611 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
1612 component separator.

1614 <m4_version_compare>: Document this change.
1615 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
1617 2007-10-30 Bruno Haible <bruno@clisp.org>
1619 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1620 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1621 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1622 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1623 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1624 Suggested by Paul Eggert.
1626 2007-10-28 Jim Meyering <meyering@redhat.com>
1628 * README-hacking: Autoconf, Automake, and Perl are required to build.
1629 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1631 2007-10-28 Jim Meyering <meyering@redhat.com>
1633 README-hacking: Recommend running autoreconf -vi.
1634 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1635 so that we use just-built tools when they're available.
1636 Suggestions from Ralf Wildenhues.
1638 2007-10-28 Jim Meyering <meyering@redhat.com>
1640 Make inter-release --version output more useful.
1642 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1643 which indicates that it is built using the 19th change set
1644 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1645 is a prefix of the commit SHA1.
1646 * build-aux/git-version-gen: New file.
1647 * configure.ac: Run it to set the version.
1648 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1649 * Makefile.am (dist-hook): Arrange so that .version appears only
1650 in distribution tarballs, never in a checked-out repository.
1651 * .gitignore: Add .version here, too. Just in case.
1652 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1653 not configure.ac, now that the version number changes automatically.
1655 Ensure that $(VERSION) is up to date for dist-related targets.
1656 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1657 git-version-gen doesn't match $(VERSION), but only for dist targets.
1659 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1691 problem reported by Bruno Haible in
1692 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.

1696 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
1697 preprocessor.
1699 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1701 Don't check for bug in HP-UX 11.00 cpp.
1702 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
1703 Use -1ull rather than -1u, since that causes problems with gnulib; see
1704 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
1706 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1722 escaping of backslash in here-documents.
1724 Fix `Deep Package' test failure on FreeBSD.
1725 * tests/torture.at (Deep Package): Do not add `.' to $PATH
1726 unnecessarily. Do not try running `/bin/sh configure' with a
1727 configure script to be found in $PATH, if the shell does not do
1728 this resolution. Fixes test failure on FreeBSD.
1730 Fix config header generation with AIX awk.
1731 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
1732 script, use helper array D_is_set, as `" 0"' does not evaluate

1774 array of banner text from a special diversion.
1775 <PARSE_ARGS_END>: No longer need awk to find banners.
1776 <TESTS>: Banners are no longer processed by main driver loop, so
1777 we no longer need case statement.
1778 (AT_BANNER): Rewrite to populate new diversion.
1779 (AT_SETUP): Each test invokes its own banner. No output is needed
1780 to the TESTS diversion.

1827 columns.
1828 (TEST_FUNCTIONS): Based on recent changes, rename...
1829 (TEST_GROUPS): ...to this.
1831 Reject FreeBSD m4.

1874 of other write errors.
1875 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): For ac_confdir,
1876 use $as_myself, not $0.
1877 (_AC_INIT_HELP): For --help=recursive, if the subdir does not

2899 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
2901 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
2902 'configure' will fail if the shell lacks proper support for shell
2903 functions. Suggested by RMS.
2905 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
2907 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
2908 about Solaris /bin/printf '%010000x' 123. Problem reported by
2909 Bruno Haible.
2911 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
2913 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
2914 for a.* when searching for executables, as this prevents users
2915 from having files like a.c. Problem reported by Ralf Wildenhues in:
2916 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
2917 This fixes a problem introduced on 2000-12-19.
2919 2007-04-26 Paul Eggert <eggert@cs.ucla.edu>
2921 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
2922 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
2923 via Bruno Haible.
2925 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
2927 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
2928 AC_CHECK_TYPE, AC_CHECK_TYPES.
2929 * doc/autoconf.texi (Generic types): C types must be type-names
2930 (the C terminology), not type-ids (the C++ term). C++ types
2931 must not be anonymous.
2932 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
2933 for C++; this drops support for anonymous struct and union types,
2934 which were problematic anyway.
2935 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
2936 for C++.
2938 2007-04-12 Jim Meyering <jim@meyering.net>
2940 * doc/autoconf.texi (Libraries): Typo fix: insert missing "in".

2950 * doc/autoconf.texi (Generic Types): Document the restrictions
2951 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
2952 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
2953 with objects too. Document the restrictions on its use.
2954 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
2955 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
2956 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
2957 works but the latter doesn't, then it's a valid type.
2958 This lets people use function types and so forth.
2959 For C++ there doesn't seem to be a simple solution, so leave it alone.
2960 (AC_CHECK_SIZEOF): Allow argument to be a variable.
2961 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
2962 AC_CHECK_TYPE; that wasn't documented or necessary.
2964 2007-04-11 Stepan Kasal <kasal@ucw.cz>
2966 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
2967 when cross-compiling.

2979 2007-04-06 Paul Eggert <eggert@cs.ucla.edu>
2981 * doc/autoconf.texi (Particular Types): AC_C_LONG_DOUBLE is now
2982 obsolescent. Suggested by Bruno Haible.
2983 * NEWS: Document this.
2985 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
2987 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
2988 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
2989 default still has the problem. Problem reported by Bruce Korb.
2991 2007-03-28 Stepan Kasal <kasal@ucw.cz>
2992 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2994 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix a

3005 more pitfalls.
3007 2007-03-23 Paul Eggert <eggert@cs.ucla.edu>
3009 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
3010 checks for unsigned long long int.
3012 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
3014 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
3015 nonstandard grep R.E. escape sequences.
3017 2007-03-17 Jim Meyering <jim@meyering.net>
3019 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3020 (Limitations of Usual Tools): Also list \< and \>, and mention that
3021 HP-UX's grep, like the one from Solaris, does not support that syntax.
3023 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3025 * doc/autoconf.texi (Specifying Names): `--host' does not
3026 change the build type.
3028 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3030 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
3031 suggests AC_CONFIG_HEADERS.
3032 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using
3033 AC_CONFIG_HEADERS. Problem reported by
3034 Peter O'Gorman.

3038 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Fix typo "__LITLE_ENDIAN__".
3039 Problem reported by Paolo Bonzini in:
3040 http://lists.gnu.org/archive/html/autoconf-patches/2007-02/msg00024.html
3041 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
3042 universal binaries. Problem reported by Elias Pipping.
3044 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
3046 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
3047 * doc/autoconf.texi (C Compiler): Document this. There is a new
3048 extra argument ACTION-IF-UNIVERSAL.
3049 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
3050 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
3051 Reindent for sanity's sake.
3053 2007-02-24 Eric Blake <ebb9@byu.net>
3055 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
3056 copyright.
3057 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
3058 * lib/autotest/general.m4 (AT_INIT): Likewise.
3059 (_AT_DECIDE_TRACEABLE): Fix syntax highlighting.
3061 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3063 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
3064 status of rm so we know when it failed.
3065 If cleaning of test dir failed before running the test, warn.
3066 Output the line separator in verbose mode before the warning
3067 to make clear the warning belongs to the following test.
3069 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
3071 * doc/autoconf.texi (Parentheses): Mention problem with (( in
3072 shells.

3075 and Paul Eggert <eggert@cs.ucla.edu>
3077 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix quoting
3078 errors introduced in last change.
3080 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
3082 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
3083 an actual carriage return. Use "ac_cr" to contain the actual
3084 carriage return.
3085 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
3086 with traditional Awk and begin.
3087 * tests/torture.at (Limitations of Builtins): Document the problem
3088 with Bash 2.03 printf.

3092 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
3094 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
3095 input from /dev/null in awk test, so even Solaris /usr/bin/awk
3096 will not wait for input with a script containing only a BEGIN
3097 rule.
3099 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
3101 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version

3121 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
3123 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
3124 latest version.
3125 (Shell Substitutions): Note problems with @{var:=value} etc.
3126 Add a new section for problems with @{#var} etc. Problem noted
3127 by Ralf Wildenhues. See:

3130 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3132 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3133 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3134 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3135 substitution will still be done by the special code.
3136 Report by Jim Meyering.
3138 * doc/autoconf.texi (File System Conventions): Mention that
3139 $PATH_SEPARATOR is for the build system only.

3151 Report against Automake by Patrick Welche.
3153 2007-01-15 Stepan Kasal <kasal@ucw.cz>
3155 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
3157 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3159 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3160 early on the reader side, drop stderr of the input to avoid
3161 `broken pipe' error output; this may happen even with shell
3162 builtin `echo' of some bash versions. Reports by Ian Macdonald
3163 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3165 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3167 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

3177 Fix some wording problems noted by Paolo Bonzini in:
3178 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3179 * doc/autoconf.texi (Signed Overflow Examples): Give more
3180 discussion about the allow_superuser_privileges example,
3181 and change it a bit to make things clearer.
3182 (Optimization and Wraparound): Clarify whether the compiler
3183 will generate an infinite loop for the example derived from
3184 Autoconf's mktime test.
3185 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3186 Also, clarify unsigned multiplication overflow.
3188 2007-01-04 Eric Blake <ebb9@byu.net>
3190 * bin/Makefile.am (RELEASE_YEAR): New macro.
3191 (edit): Use it to supply correct copyright year to scripts.
3192 * bin/autoconf.as (version): Use it.
3193 * bin/autoheader.in ($version): Likewise.
3194 * bin/autom4te.in ($version): Likewise.
3195 * bin/autoreconf.in ($version): Likewise.
3196 * bin/autoscan.in ($version): Likewise.
3197 * bin/autoupdate.in ($version): Likewise.
3198 * bin/ifnames.in ($version): Likewise.
3200 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3202 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3203 feedback. The most important changes document what happens when
3204 you convert an out-of-range value to a signed integer type, and
3205 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3206 a + b.
3208 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3209 rewrite, taking notions from the recent discussion on the gcc and
3210 autoconf mailing lists; please see
3211 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3212 and follow the many links.
3213 (Integer Overflow Basics, Signed Overflow Examples):
3214 (Optimization and Wraparound, Signed Overflow Advice):
3215 (Signed Integer Division): New sections.
3217 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3219 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3220 preprocessor macro arguments in traced name.
3221 * doc/autoconf.texi (Defining symbols): Document longstanding
3222 support for AC_DEFINE-ing macros with arguments, and document
3223 behavior when the same variable has multiple AC_DEFINEs.
3224 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3225 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3226 macros directly, giving much shorter and simpler code.
3228 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3230 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3231 space before "$ac_configure_args" to prevent a 'config.status
3232 --recheck' failure if ac_configure_args doesn't contain a leading
3233 space. This works around a problem with the XEmacs configure.ac,
3234 which uses the (undocumented) ac_configure_args variable
3235 inconsistently with Autoconf.
3237 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3239 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3240 Include <limits.h>, and use its INT_MAX to rewrite the
3241 j loop so that it does not overflow 'int'. Problem reported by
3242 Ralf Wildenhues in
3243 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3244 Play it safe by shifting left by 1 rather than multiplying by 2,
3245 as GCC is less likely to optimize this away when the value
3246 is signed (when it assumes overflow leads to undefined behavior).
3247 Also, don't assume time_t uses two's complement.
3249 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3251 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3252 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3253 dumps core on it. Report by Tim Rice.
3255 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3257 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3258 --disable-option-checking to --help output even when
3259 AC_PRESERVE_HELP_ORDER is not used.
3260 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3261 --with argument, rather than argument with [-.] replaced by
3262 underscores.
3263 * NEWS: Fix typo in previous change; the news was in the
3264 wrong section.
3266 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3268 * NEWS: Warnings are now generated by default for unknown
3269 --enable-* and --with-* options.
3270 * doc/autoconf.texi (Option Checking): Renamed from
3271 (Configure Option Checking). Tighten up the wording a bit.
3272 (External Software, Package Options): Cross-reference to Option
3273 Checking, and use this to shorten our section.
3274 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3275 "$x" to test "x$foo" != x.
3276 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3277 Don't warn if $enable_option_checking is "no".
3278 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3279 ac_unrecognized_opts to the empty string.
3280 Don't echo the unrecognized opts, as this might mishandle
3281 backslashes or leading -.
3282 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3283 usage next to the other --disable-FEATURE options in the
3284 help string.
3286 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3288 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3289 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3290 Print warning for unrecognized --with and --enable options
3291 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3292 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3293 Disable option checking when subdirs are configured.
3294 (AC_OUTPUT): If warnings are enabled, print warning about
3295 unrecognized --with and --enable options at the end of
3296 the configure output (as well as at the beginning).
3297 * doc/autoconf.texi (Option Checking): New node.
3298 Document new option warning functionality.
3300 2006-12-16 Eric Blake <ebb9@byu.net>
3302 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3303 * NEWS: Start news for current version.
3305 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3307 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3308 Define HAVE_GETMNTENT to 1, not to the empty string.
3309 Problem originally reported by Jochen Friedrich in
3310 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3312 This change prompted by a problem report by Andrey Simonenko in
3313 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3314 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3315 object-like macros only, in the traditional portable character
3316 set.
3317 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3318 Warn about attempts to define things that are not identifiers.
3319 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3320 awful hack that AC_DEFINEd macro names containing parentheses.
3322 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3324 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3325 too drastic, even if Texinfo in theory requires it for info mode.
3327 (config.status Invocation): Renamed back from Recreating a
3328 Configuration).
3329 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3330 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3332 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3334 * NEWS: Version 2.61a.
3336 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3337 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3339 * NEWS: Document changes with echo and printf, and the lack
3340 of limits on the total size of multi-line values of substituted
3341 variables, and the AC_FUNC_FSEEKO fix.
3343 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3345 * doc/autoconf.texi (Writing Autoconf Input): Renamed from

3352 (Writing Testsuites): Renamed from Writing testsuite.at.
3353 (Autom4te Cache): Renamed from autom4te.cache.
3355 * BUGS: Remove mention of VPATH problem, since it's now documented
3356 not to be a bug in the Autoconf build procedure itself, but rather
3357 a problem with the proprietary `make' programs.
3359 * doc/autoconf.texi (Build Directories): Add a cross reference
3360 to VPATH and Make.
3362 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3363 * doc/standards.texi: Sync from gnulib.
3365 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3366 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3367 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3368 generated automatically.
3370 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3372 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3373 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3374 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3376 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3378 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3379 `CEOF$ac_eof' special marker, the awk script cannot contain a
3380 line matching `^CEOF', so this is not needed any more.
3381 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3382 special marker in the test.
3384 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3386 * tests/tools.at (autom4te preselections): Use `find -newer';
3387 remove one of the sleeps.
3389 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3390 more readable, using ...
3391 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3393 * doc/autoconf.texi (autoheader Invocation): Do not double-
3394 quote the parameter of `AH_BOTTOM' in the example.
3396 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3398 * doc/autoconf.texi (Configuration Headers): Remove the
3399 example with multiple input files.
3400 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3401 multiple input files.
3403 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3405 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3406 creating the awk substitution script, handle one input line at a
3407 time, so that the maximum length of a substituted (multi-line)
3408 value is not limited by the size of the sed pattern space.
3409 The trade-off is a slightly repetitive sed script.
3410 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3411 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3412 * tests/torture.at (Substitute a 2000-byte string): Increase the
3413 test with several long lines, they should not be caught by sed
3414 limits any more.
3416 * tests/tools.at (autom4te preselections): New test, to flag
3417 entries missing from autom4te.cfg.
3418 Report by David Byron <dbyron@hheld.com>.
3420 * tests/torture.at (Substitute a 2000-byte string): Actually use
3421 AC_PROG_AWK, so the last change works as intended.
3422 (Substitute and define special characters): Likewise.
3423 (Substitute a newline): Likewise.
3425 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3426 instead of `awk' consistently.
3427 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3428 * tests/torture.at (Torturing config.status): Test both the
3429 result of AC_PROG_AWK and plain awk.
3430 (Substitute a 2000-byte string): Likewise.
3431 (Substitute and define special characters): Likewise.
3432 (Substitute a newline): Likewise.
3434 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3436 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3437 can be assigned to a function pointer. Problem reported by
3438 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3439 part of a patch by Ralf Wildenhues in that same bug report.
3441 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3443 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3444 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3446 2006-12-01 Eric Blake <ebb9@byu.net>
3448 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3449 cross-compiling from cygwin to mingw.
3450 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3451 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3452 to lib/autoconf/c.m4.
3454 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3456 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3457 string for more reliable failure. Wrap the entire test that
3458 causes the broken Solaris printf to dump core, in a subshell,
3459 so the segmentation fault message is reliably suppressed.
3460 Fix shell expansion errors by using /usr/ucb/echo always;
3461 avoid an error on systems without it by another subshell.
3462 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3463 subshell-$as_echo to `as_echo', for better error message.
3465 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3467 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3468 `BASH_SOURCE' contain a newline, set them to empty, as they may
3469 not be unset.
3471 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3473 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3474 years and is too hard to maintain now. The last straw was
3475 reported by Jerker Baeck in
3476 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3477 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3478 * doc/autoconf.texi (Particular Functions): Move
3479 AC_FUNC_SETVBUF_REVERSED from here...
3480 (Obsolete Macros): ... to here. Say that it does nothing now.
3481 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3482 Turn into (almost) a no-op.
3484 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3485 (AC_C_VOLATILE):
3486 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3487 These macros are obsolescent and new applications shouldn't need them.
3488 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3489 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3490 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3491 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3492 (AC_FUNC_VPRINTF): Likewise.
3493 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3494 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3495 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3497 * doc/autoconf.texi (Setting Output Variables): Mention that
3498 @VAR1@VAR2 has unspecified behavior. Problem reported by
3499 Ralf Wildenhues.
3500 * NEWS: Mention this.
3502 * Makefile.am: Put only a single '#' into the copyright notice,
3503 so that it's also present in the output file. Standardize wording
3504 in makefile copyright notices to match GNU coding standards.
3505 * bin/Makefile.am: Likewise.
3506 * doc/Makefile.am: Likewise.
3507 * lib/Makefile.am: Likewise.
3508 * lib/freeze.mk: Likewise.
3509 * lib/autoconf/Makefile.am: Likewise.
3510 * lib/autoscan/Makefile.am: Likewise.
3511 * lib/autotest/Makefile.am: Likewise.
3512 * lib/m4sugar/Makefile.am: Likewise.
3513 * man/Makefile.am: Likewise.
3514 * tests/Makefile.am: Likewise.
3515 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
3516 one-line file.
3518 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3520 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3521 in the sed script that mangles the awk script: delete up to the
3522 first exclamation mark only.
3523 * tests/torture.at (Substitute and define special characters):
3524 Test '!' too.
3526 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3528 Rewrite config files generation: avoid quadratic growth in
3529 the number of substituted variables by using awk instead of sed
3530 for the bulk of the substitutions.
3531 * NEWS: Mention this.
3532 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3533 forbidden in the output (and thus input) file.
3534 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3535 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3536 generate just one large awk script for substitutions,
3537 eliminating much of the earlier complexity, while adding some
3538 new complexity. Only expand the substitution templates at
3539 configure time, for smaller configure script size. If
3540 _AC_SUBST_FILES are used, test 'awk' for working getline support
3541 at config.status time. If absent, interpolate through the
3542 shell. The awk script was written with much help
3543 from Paolo Bonzini and Paul Eggert.
3544 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3545 (_AC_SED_FRAG_NUM): Likewise.
3546 (_AC_SUBST_CMDS): Renamed from...
3547 (_AC_SED_CMDS): ...this.
3548 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3549 * tests/torture.at (Substitute a 2000-byte string): Also
3550 substitute a line with 1000 words, and a variable with several
3551 long lines.
3552 (Substitute and define special characters): Test awk special
3553 characters, and put substitution input strings `@foo@' in the
3554 output, to test that no recursion happens; test several other
3555 combinations from Paolo Bonzini.
3557 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3559 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3560 that replaced echo with AS_ECHO where this wasn't necessary.
3561 Problem reportd by Ralf Wildenhues.
3562 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3563 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3564 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3566 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3568 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3570 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3572 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3573 that traditional Awk lacks 3-arg "split". It has it.
3574 Mention that FS must be a single character, and a few other
3575 99-byte limits of traditional Awk.
3576 Mention that if (i in a) doesn't work with traditional Awk.
3578 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3580 * tests/autotest.at (BSx641-newline in command):
3581 (BS-BS-newline in command, BSx640-newline in command):
3582 (Newline-CODE-BS-newline in command):
3583 (Single-quote-BS-newline in command):
3584 (Single-quote-newline-BS-newline in command):
3585 Use printf '%s\n' instead of echo, for portability to hosts
3586 where echo interprets backslashes. This will break on hosts
3587 that lack printf, but for now let's assume all such hosts
3588 are dead (if not, we should get reports of test failures).
3590 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3592 'echo' has some portability problems, when given a first argument
3593 with a leading '-', or when given any argument containing '\'.
3594 Avoid using 'echo' in these cases.
3595 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
3596 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
3597 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3598 * lib/autotest/general.m4 (AT_INIT): Likewise.
3599 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
3600 argument might be unportable.

3619 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3620 * bin/autoconf.as: Redo verbose flag implementation, as the old
3621 scheme wouldn't work with AS_ECHO.
3622 * lib/autotest/general.m4 (AT_INIT): Likewise.
3623 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3624 Don't use ECHO_T, since ECHO_N is now reliable.
3625 * lib/autotest/general.m4 (AT_INIT): Likewise.
3626 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3627 rather than using a here-document to put the script into a file.
3628 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3629 use AS_ECHO.
3630 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3631 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3632 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3633 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3634 * lib/autotest/general.m4 (AT_SETUP): Likewise.
3635 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
3636 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3637 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3638 operand, as AS_ECHO requires. Avoid double file name expansion.
3639 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3640 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3641 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3642 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3643 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3644 Double-quote strings that would otherwise contain M4 comments.
3645 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3647 * configure.ac (AC_INIT): Bump to 2.61a.
3648 * NEWS: Likewise.
3650 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3652 Version 2.61.
3654 * configure.ac (AC_INIT): Bump to 2.61.
3655 * NEWS: Likewise.
3657 * tests/autotest.at (Macro with backslash in a test title):
3658 Comment out for now, as this tests neither fails nor passes
3659 reliably. Problem reported by Ralf Wildenhues.
3661 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3663 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
3664 in previous change, which caused test failures.
3666 2006-11-16 Stepan Kasal <kasal@ucw.cz>
3668 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
3669 code for --enable, --disable, --with, and --without to...
3670 (_AC_INIT_PARSE_ENABLE): ... a new macro.
3671 * doc/autoconf.texi (Package Options):

3674 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3676 Import these changes from config via gnulib:
3678 2006-11-15 Ben Elliston <bje@gnu.org>
3680 From Josselin Mouette <joss@debian.org>:

3717 no further ado.
3719 2006-11-05 Karl Berry <karl@gnu.org>
3721 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.

3735 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
3737 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
3738 benefit of platforms like Solaris+GCC where it is common to have a
3739 non-working g++ installation.
3741 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3742 and Joel E. Denny <jdenny@ces.clemson.edu>
3743 and Paul Eggert <eggert@cs.ucla.edu>
3745 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
3746 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
3747 ./micro-suite.
3749 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3751 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
3752 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
3753 Imported from a similar patch to gnulib by Bruno Haible.
3755 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3757 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

3766 Matthew Woehlke.
3768 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3770 * tests/torture.at (Configuring subdirectories): Do not skip
3771 Automake 1.10 nor future Automake 11.1 (sic).
3773 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
3774 and Stepan Kasal <kasal@ucw.cz>
3776 Handle special characters in test case titles correctly.
3777 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
3778 properly.
3779 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
3780 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
3781 argument. Extend to check titles printed by ./micro-suite and
3782 ./micro-suite -l and the title in micro-suite.log.
3783 (Backquote in a test title,
3784 Single-quote in a test title,
3785 Double-quote in a test title): Don't expect failure anymore.
3786 (Backslash in a test title): Put a non-whitespace character after the
3787 backslash so that Bourne shells might actually see it as an escape
3788 sequence.
3789 (Brackets in a test title,
3790 Pound in a test title,
3791 Comma in a test title,
3792 Quoted Macro in a test title,

3795 (Macro with backquote in a test title,
3796 Macro with double-quote in a test title,
3797 Macro with backslash in a test title): New tests expected to fail.
3798 * tests/torture.at (#define header templates): M4-quote this title in
3799 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3800 The visible effect was a stray [] in the testsuite output.
3802 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3804 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3805 `trap ... 0' inside a function, for AIX sh.
3807 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3809 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3810 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3811 5363) simply issues a warning when dividing by zero at compile
3812 time. Problem reported by Elias Pipping.
3814 2006-10-26 Eric Blake <ebb9@byu.net>
3816 * THANKS: Update.
3817 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3818 show effect on macros that expand with commas.
3819 Reported by Joel E. Denny.
3821 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
3822 Also work with M4 1.4.8.
3824 2006-10-25 Paul Eggert <eggert@cs.ucla.edu>
3826 * doc/autoconf.texi (Slashes): Document Tru64 4.0 bug reported by
3827 Jim Meyering.
3829 2006-10-25 Stepan Kasal <kasal@ucw.cz>
3831 * tests/tools.at (autom4te --force): New test, verifies that
3832 `--force' always rewrites the output file.
3834 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
3836 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm

3843 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
3845 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3846 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3847 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3848 reported by Nelson H. F. Beebe for Coreutils 6.4.
3850 * tests/tools.at (autoconf --trace: user macros): Remove test
3851 for tracing multiline macros, since m4 1.4.7a uses a different
3852 way to number lines. Problem reported by Ralf Wildenhues.
3854 2006-10-24 Stepan Kasal <kasal@ucw.cz>
3856 * bin/autom4te.in (handle_m4): Do not redirect stdin to
3857 /dev/null since the heuristics for interactive behaviour was
3858 fixed in CVS m4.
3860 * bin/autom4te.in: With --force, always refresh the output
3861 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
3863 * bin/autoconf.as: Fix the verbose message at the end.
3865 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

3880 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
3881 AC_CACHE_CHECK_INT, since it's no longer public.
3882 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
3883 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
3885 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3887 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
3889 2006-10-19 Eric Blake <ebb9@byu.net>

3903 Standards.

3911 2006-10-14 Stepan Kasal <kasal@ucw.cz>
3913 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
3914 looking for special shell characters.
3915 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
3916 macro defined by AS_VAR_PUSHDEF before passing it as a
3917 parameter.
3918 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
3919 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

3928 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
3930 (Imported from Automake.)
3931 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3932 which incorrectly sets the mode of an existing destination
3933 directory. In some cases the unpatched install-sh could do the
3934 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3935 system. We hope this is rare in practice, but it's clearly worth
3936 fixing. Problem reported by Alex Unleashed in
3937 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3938 Also, don't bother to check for -m bugs unless we're using -m;
3939 suggested by Stepan Kasal.
3941 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
3943 Import this change from Automake:
3945 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

3947 is enabled by default with gnu and gnits strictness.
3948 Report from Bruno Haible.
3950 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
3951 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
3952 gnu and gnits modes.
3954 Import this change from Config:
3956 2006-09-20 Ben Elliston <bje@gnu.org>
3957 * build-aux/config.sub (score, score-*): New.
3959 Import this change from Gnulib:
3961 2006-09-16 Karl Berry <karl@gnu.org>
3962 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
3963 to avoid sectioning errors.
3965 Import these changes from Texinfo:
3967 2006-10-04 Karl Berry <karl@gnu.org>
3968 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
3969 (\quoteexpand): rename to \rquoteexpand.
3970 (\codequoteleft): new def, to look for @set codequotebacktick.
3971 (\lquoteexpand, \quoteexpand): new defs.
3972 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
3973 (\code): must use new \...Char values, since now ` is active.
3975 2006-08-26 Karl Berry <karl@gnu.org>
3976 * build-aux/texinfo.tex (\textdegree): New command.
3978 2006-08-12 Karl Berry <karl@gnu.org>
3979 * build-aux/texinfo.tex (error \box0): smaller font.
3981 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3983 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
3985 2006-10-13 Stepan Kasal <kasal@ucw.cz>
3987 * doc/autoconf.texi (Autoheader Macros): Warn that the text
3988 added to the template can get mangled.
3990 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3992 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
3993 include the default headers, and redefine obstack_chunk_alloc
3994 and obstack_chunk_free. Fixes false failure with glibc.
3996 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
3998 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
3999 for backward compatibility with Libtool 1.5.22. Problem reported
4000 by Ralf Wildenhues.
4002 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4004 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
4005 AC_PROG_CC.
4006 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
4008 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4010 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
4011 the NonStop platform.
4012 * doc/autoconf.texi (Posix Variants): Likewise.
4013 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4015 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4016 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4017 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4018 Use a better substitute, by inspecting the output of "ls"
4019 rather than just using ":".
4020 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4021 rather than AS_EXECUTABLE_P, since we needn't worry about
4022 non-regular files here.
4024 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4025 due to configuration hassles with this. See Tonya Underwood's report
4026 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4027 * doc/autoconf.texi (Special Shell Variables): Likewise.

4030 Stepan Kasal <kasal@ucw.cz>
4032 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
4033 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
4035 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4037 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4038 initialization which is not inherited through the environment
4039 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4040 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4042 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4044 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4045 problems with mkdir -p -m.
4047 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4049 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4050 comment about ac_cpp_err; it was incorrect, and anyway
4051 ac_cpp_err is being removed below.
4052 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4053 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4054 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4055 nobody uses it.
4056 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4057 with werror_flag and conftest.err and so forth. This is more
4058 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4059 and anyway the user shouldn't normally want to see this gorp logged.
4060 Problem reported by Ralf Wildenhues.
4061 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4062 empty, not 'no', since the rest of the code uses 'test -z'.
4064 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4066 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4067 Use a single call to AC_DO_TOKENS rather than multiple, for
4068 efficiency.
4069 (_AC_LINK_IFELSE): Test that resulting file is executable.
4070 Problem reported by mwoehlke in
4071 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4073 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4074 than creating a file to use with test -x; this is much faster.
4076 2006-10-02 Bruno Haible <bruno@clisp.org>
4078 * lib/autom4te.in (Automake-preselections): Add
4079 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4081 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4083 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4084 standard error, `experr' should be used, not `expout'.
4086 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4088 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4089 fseeko testing program twice; just use the earlier result.
4090 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4091 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4092 still doesn't let the program compile.
4093 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4094 failed.
4096 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4097 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4098 include it, without including anything else.
4099 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4100 expressions.
4101 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4103 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4105 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4106 `error.h', and include it, for a `error_at_line' prototype.
4107 Use a nonempty format string in the link test.
4108 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4109 for a declaration of wait3.
4111 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4113 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
4114 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4115 can apply to constants too, and that it checks for macro defns.
4116 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4117 and simply cast the identifier to void. This handles structure
4118 values. Problem reported by Ralf Wildenhues.
4119 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
4121 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4123 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
4124 structure, and function symbols.
4126 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4128 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
4129 member.

4143 present.
4144 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add
4145 parentheses.

4175 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
4176 --error-output, to avoid warnings with M4 2.0.
4178 2006-09-19 Stepan Kasal <kasal@ucw.cz>
4180 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

4189 2006-09-14 Stepan Kasal <kasal@ucw.cz>
4191 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
4192 mistaken comment: the path has to be relative; do not use
4193 the path at runtime.
4195 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4197 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the
4198 argument to `--prefix' for sub-configure scripts.

4201 for both changes.
4202 * doc/autoconf.texi (Setting Output Variables): Fix example to
4203 not show `--silent' being passed to a `configure' re-run.
4205 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
4207 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
4208 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
4209 for the existence of the directory at configure-time. That's
4210 too late, anyway. Problem reported by Stefan Seefeld.
4212 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
4213 7.1.4 /usr/bin/posix/sh described by Tim Rice in
4214 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
4216 2006-09-11 Stepan Kasal <kasal@ucw.cz>
4218 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
4219 works with GNU M4 1.4.3 again; make the normalized form
4220 match the current m4 message; fix the description.
4221 * test/tools.at (autom4te cache): Adapt to the change.
4223 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
4225 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
4226 to catch glibc bug 2821
4227 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
4229 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
4230 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
4231 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
4232 assume C89.
4234 2006-09-08 Stepan Kasal <kasal@ucw.cz>
4236 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

4252 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4254 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
4255 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
4256 accept files with extension `.f'. For consistency, also prefer
4257 xlf over f77.

4276 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
4278 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
4279 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
4280 except the first two arguments are reversed.
4281 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
4282 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
4283 caches nor outputs a diagnostic. Suggested by Bruno Haible.

4293 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
4294 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
4295 programs should use their Gnulib counterparts.
4296 * doc/autoconf.texi (Particular Functions): Likewise.
4297 (Macro Names, testsuite Invocation): Replace uses of these
4298 obsolete macros with uses of non-obsolete macros.

4327 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
4328 for the default, which the user can override.
4329 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
4330 deal with LEXLIB.
4331 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
4332 didn't work if some values were cached but not others. Test for
4333 broken lex libraries like native ia64-hp-hpux11.22; see
4334 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4335 work around the problem by preferring an empty LEXLIB to -lfl or
4336 -ll. Let the user set LEXLIB='' to indicate no library needed.
4338 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
4339 * README: Likewise.
4340 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

4465 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
4466 * doc/autoconf.texi (Header Templates, Default Includes):
4467 (Particular Functions, Generic Functions, Header Portability):
4468 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
4469 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):

4481 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
4482 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee

4487 * doc/autoconf.texi (Limitations of Usual Tools): Document sed

4503 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
4504 --help' should mention that `--version' outputs configuration
4505 settings. Report by Bruno Haible.
4507 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
4509 Fix test suite failures reported by Pierre in

4525 less skeptical about "volatile", after discussion with
4526 Bruno Haible on bug-gnulib.
4527 (Limitations of Usual Tools): Warn about sed stripping
4528 leading white space from text. From Bruno Haible.
4530 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4532 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
4533 compiler complains about it, even if things works after the
4534 complaint. Problem reported by Peter O'Gorman.
4536 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
4537 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
4538 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
4540 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
4542 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

4554 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
4555 under AC_C_VOLATILE.

4566 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4567 more globally, since the 2006-06-30 patch didn't suffice. Problem
4568 reported by Keith Marshall. Also, don't bother with builddir2,
4569 since it shouldn't be needed any more.
4571 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
4573 * doc/autoconf.texi (Generic compiler characteristics):
4574 Document AC_COMPUTE_INT. Fix wrong statements on Default

4590 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4592 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4593 Require that long long int be at least 64 bits wide. C99 requires
4594 this and enough programs depend on it so we should check for it.
4595 Bruno Haible reports in
4596 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4597 that long long int is 32 bits wide with some nonstandard compilers.
4598 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
4600 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4602 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4603 to a nonexistent file, so that we don't have to worry about
4604 a local site configuration that doesn't use /usr/local.
4605 Problem reported by Keith Marshall in
4606 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4608 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4610 * doc/autoconf.texi: Be more consistent about using @acronym with
4611 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4612 quite right (it talked about "OSF/Tru64", even though the
4613 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4614 and it even mentioned "OSF 4"!) and at this point there's little
4615 reason to talk about OSF any more, since it died in 1994.
4616 (Specific Compiler Characteristics): Simplify example of
4617 negative-size array.
4618 (File Descriptors): Reorder to make the text flow better.
4619 Remove joke about "appreciate the various levels"; I didn't get it.

4621 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4622 (File Descriptors, Limitations of Usual Tools):
4623 Tone down the advice against renaming or removing open files.
4624 (Limitations of Usual Tools): Add a new section, on 'rm'.
4626 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4628 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4629 -lXt in LIBS, idea from Karsten Hopp; this was due since
4630 this change:
4632 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4633 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4634 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4635 (which belong to Xt, not X itself). See Debian bug 327655.
4637 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4639 * configure.ac (AC_INIT): Bump to 2.60a.

4659 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4660 not defined.
4661 * doc/autoconf.texi (Changed Directory Variables): New node,
4662 to document the whole `datarootdir' business a bit better.
4663 * NEWS: Update.
4664 * tests/torture.at (datarootdir workaround): Extend test.
4665 Prompted by report by Alexandre Julliard.
4667 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4669 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility

4671 fix reported by Larry Jones.
4673 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4675 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4676 about literal '${datarootdir}' if a definition is found in the
4677 output file.
4679 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4681 * NEWS: Use "M4" rather than "m4" when appropriate.
4682 Problem reported by Eric Blake.
4683 * doc/autoconf.texi: Likewise.
4684 Use @acronym around BSD, GCC, and GNU when appropriate.
4685 (Why GNU M4): Renamed from "Why GNU m4".
4686 (Redefined M4 Macros): Mention that Posix
4687 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4688 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4689 to int.
4691 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4693 * bin/autom4te.in (handle_output): Do not forbid the empty
4694 pattern.
4695 * tests/tools.at (autoconf: the empty token): New test.
4697 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4699 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4700 calls, so that we do not care whether they are LIFO or FIFO;
4701 in the m4_wrap, do not check which diversion is the topmost
4702 one, just check that the stack is balanced at the end.
4703 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4704 base diversion forever--pop the previous diversion before
4705 opening the new one; consequently, remove the m4_wrap call.
4706 * lib/autotest/general.m4 (AT_INIT): Likewise.
4707 * tests/m4sugar.at: Do not use
4708 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
4710 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4711 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4713 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4714 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4715 Rework example of m4wrap token-pasting trouble so that it doesn't
4716 care whether it's LIFO or FIFO.
4717 Fix some "contrary to"s that are awkward in English.
4719 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4721 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4722 to `yes' instead of `int$1_t' if the type is found, for more
4723 consistent configure output (where $1 is the number of bits).
4724 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4725 Suggested by Bruno Haible.
4727 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4728 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4729 with system headers. Report by Bruno Haible.
4731 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4733 * config/config.guess, config/config.sub: Sync from upstream.
4735 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4736 in order to avoid picking up an older installed frozen m4sh.m4f.
4737 Besides an outdated shell startup, this could have been created
4738 by an earlier M4 version with incompatible frozen file format.
4740 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4742 * README: Recommend m4 1.4.4 instead of 1.4.3..
4743 * doc/autoconf.texi: Likewise.
4744 (Special Chars in Names): Say that $(.FOO) is portable, as
4745 suggested by Stepan Kasal.
4746 (Installation Directory Variables, Build Directories):
4747 (Automatic Remaking, Subdirectories, Fortran Compiler):
4748 (Making testsuite Scripts, Defining Directories):
4749 Quote variable usages better.
4750 (Making testsuite Scripts): Add clean-local rule to makefile
4751 snippet, by Eric Blake.
4752 (Installation Directory Variables): Fix table item font.
4753 Reword slightly to clarify. Generalize advice about
4754 not using special characters to include all file-related
4755 vars, not just VPATH.
4756 (Special Chars in Variables): Warn about special characters in
4757 $(srcdir) too.
4758 (Assignments): Clarify default-value example as suggested by
4759 Ralf Wildenhues in
4760 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4761 (Special Shell Variables): Note leading ./ or ../, as suggested
4762 by Eric Blake.
4763 (Limitations of Builtins): Under cd, warn about CDPATH.
4764 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4765 Ralf Wildenhues.
4767 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4769 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4770 `@var', for texi2html.
4771 (Systemology): Some more word wrapping, for DVI output.
4772 (autom4te Invocation): The short option for `--melt' is `-M',
4773 not `-m'.
4775 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4777 * doc/autoconf.texi: More formatting and English tweaks,
4778 many suggested by Ralf Wildenhues.
4779 Reword to avoid "@code{...}'s" and the like, since it's ugly
4780 with Emacs info mode. discontents -> woes.
4781 Put a few "will"s back. time stamp -> timestamp.
4782 side-effect -> side effect.
4784 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4786 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4787 Warn about $@ not persisting. Problem reported by Julien Danjou in
4788 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4789 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4790 Mention other special chars, too.
4792 2006-06-14 Eric Blake <ebb9@byu.net>
4794 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4796 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4798 * doc/autoconf.texi: Some systematic minor improvements, as
4799 follows. Use "makefile" when talking about makefiles
4800 generally (which might be named "makefile" or "Makefile" or even
4801 "foo.mk"), "Makefile" when talking about a specific makefile
4802 called "Makefile". This unclutters the text from weird quotes
4803 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4804 values" rather than "@var{foo}s" and similar constructs containing
4805 "}s". Use "Make rules" rather than "Makefile rules". Minor
4806 English-language improvements. Change the prefix "sub-" to "sub"
4807 and "re-" to "re".
4808 Put blank lines around examples more consistently.
4809 Avoid "rather" and "very" as intensifiers.
4810 Avoid "will" as an auxiliary.
4811 (Limitations of Make): Split this node into....
4812 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4813 (Leading _ in Macro Names, Backslash-Newline-Newline):
4814 (Backslash-Newline Comments, Long Lines in Makefiles):
4815 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4816 (obj/ and Make, make -k Status, VPATH and Make):
4817 (VPATH and Double-colon, $< in Explicit Rules):
4818 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4819 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4820 New nodes, resulting from splitup of Limitations of Make.
4821 All cross-references changed. Raise the top node from
4822 a section to a chapter, and all subnodes accordingly.
4823 Redo the introductory wording to match the new organization.
4824 (Installation Directory Variables): Use an example that is
4825 closer to what Autoconf actually does. Mention that VPATH's
4826 value should not contain metacharacters or white space.
4827 (Fortran Compiler): Fix a VPATH bug in an example.
4828 (Leading _ in Macro Names): Mention that this problem is no longer
4829 of practical concern.
4830 (VPATH and Make): Reword the advice to make it clearer
4831 that Autoconf and Automake support VPATH in non-GNU make, but
4832 many packages have bugs in this area.
4833 ($< in Explicit Rules): Refer to Build Directories rather
4834 than using a (non-VPATH-safe) example.
4835 (Automatic Rule Rewriting): Mention the sort of disaster that
4836 can ensue with Solaris-style rule rewriting with VPATH.
4838 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4840 * doc/install.texi (Compilers and Options): Weaken the
4841 suggestion to use GNU make for VPATH builds.
4843 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4844 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4846 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4847 in regular expression.
4849 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4851 * doc/autoconf.texi (Installation Directory Variables):
4852 Drop extra @samp from `@table @samp' item.
4853 (Limitations of Usual Tools): Comment fix.
4854 Do not nest @samp just to point to other table items.
4855 (Writing testsuite.at) <AT_CHECK>: The second argument to
4856 `@dvar' is already @samp'ed.
4857 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4858 do not use @var in the second argument.
4860 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4862 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4863 $as_shell.exe too. Problem reported by Andreas Buening in
4864 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4866 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4868 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4869 `unused variable' compiler warning, for `-Wall -Werror'.
4870 Reported by Jaap Haitsma in
4871 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4873 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4875 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4876 case the compiler dumps core. Problem reported for
4877 OpenServer 5.0.7 by Tim Rice in
4878 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
4879 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4880 Likewise.
4882 2006-06-06 Tim Rice <tim@multitalents.net>.
4884 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4885 "ERROR" only shows up in "make check" output if there is an
4886 error.
4888 2006-06-06 Eric Blake <ebb9@byu.net>
4890 * tests/tools.at (automatically allowed tokens): Fix typo.
4892 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4894 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
4896 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
4897 typically overflows on x86 CPUs, even though the C standard
4898 requires otherwise.
4900 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4902 * configure.ac (AC_INIT): Bump to 2.59e.
4903 * NEWS: Update.
4905 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4907 Version 2.59d.
4909 * config/texinfo.tex: Sync from upstream.
4911 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4912 seen, invoke libtoolize with `--ltdl' argument.
4913 * lib/autom4te.in (Autoreconf-preselections): Adjust.
4914 * NEWS: Update.
4915 Suggested by Eric Blake.
4917 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4919 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
4920 reported by Ralf Wildenhues.
4921 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
4923 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4925 * THANKS: Update.
4927 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4929 * doc/autoconf.texi: Modernize some of the references to Solaris.
4931 2006-06-05 Stepan Kasal <kasal@ucw.cz>
4933 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
4934 message issued by AC_REQUIRE.
4935 * tests/m4sugar.at: Check m4_require's error message.
4936 * tests/base.at: Check AC_REQUIRE's error message.
4937 * tests/local.at (AT_CHECK_M4): New macro, almost identical
4938 to...
4939 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
4940 AT_CHECK_M4.
4941 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
4942 `expout' as the last parameter.
4943 * tests/tools.at: Adapt to the above change.
4945 2006-06-04 Stepan Kasal <kasal@ucw.cz>
4947 * doc/autoconf.texi (Limitations of Usual Tools): Correct
4948 information about race-free implementations of mkdir.
4950 2006-06-04 Eric Blake <ebb9@byu.net>
4952 * bin/autoreconf.in (help): Document M4 environment variable.
4953 * bin/autoconf.as (Usage): Likewise.
4954 * bin/autom4te.in (help): Likewise.
4955 * doc/autoconf.texi (autom4te Invocation): Likewise.
4957 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
4959 * NEWS: GNU make now recommended for VPATH builds.
4960 Mention that some macros are now documented to be obsolescent.
4961 * doc/autoconf.texi:
4962 Prefer "current" to "modern" to describe
4963 currently-used (albeit perhaps old-fashioned) hosts.
4964 Mention which ancient features no longer need to be worried about.
4965 setgid -> set-group-ID
4966 setuid -> set-user-ID (these are the Posix terms)
4967 Fix some misuses of "only".
4968 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
4969 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
4970 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
4971 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
4972 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
4973 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
4974 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
4975 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
4976 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
4977 Mention that these macros are obsolescent.
4978 (Installation Directory Variables): shall -> should
4979 (File Descriptors): Mention that 0, 1, 2 might get reopened.
4980 Mention that it's now safe to use 3 and 4.
4981 (Limitations of Usual Tools): cp -r is now specified by Posix.
4982 Omit longwinded and obsolescent discussion of cp -f.
4983 Modernize discussion of expr, ls.
4984 (Limitations of Make): Modernize discussion of VPATH builds.
4985 Mention $? as a workaround in some cases.
4986 * doc/install.texi (Basic Installation):
4987 Mention "./configure; make; make install" first. Be more
4988 specific about why this file is generic. Remove unnecessary
4989 parens. Remove misleading "only". Remove obsolete advice
4990 about csh. Don't say "configure" takes awhile; say it
4991 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
4992 and CC=c99 rather than CC=c89, as these are blessed by current
4993 Posix. Recommend GNU make if doing a VPATH build.
4995 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
4997 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
4998 examples involving shell prompts.
5000 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5001 and Paul Eggert <eggert@cs.ucla.edu>
5003 * doc/autoconf.texi (Here-Documents): Add details about the
5004 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5005 use "here-documents" instead of "here documents".
5007 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5009 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5011 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5013 * doc/autoconf.texi (File System Conventions): Warn about ":"
5014 anywhere in directory names.
5016 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5018 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5019 about quoting the case statement, just in case.
5020 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5021 was fixed in ksh93g; reported by Ralf Wildenhues.
5023 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5025 * doc/autoconf.texi (System Services): Do not document
5026 overriding EXEEXT via ac_cv_exeext=ext.
5027 (Particular Programs) <AC_PROG_MKDIR_P>:
5028 Document that ${MKDIR_P} understands --.
5029 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5030 comment.
5032 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5034 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5035 argument with leading hyphen. Problem reported by Paul Eggert.
5037 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5039 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5040 about quoting ac_try: quote all of it, if any of it seems suspicious.
5041 This means we don't have to worry about ${ or sed any more.
5042 Also, double-quote the case statement, to work around misuses via
5043 underquoting as reported by Ralf Wildenhues in
5044 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5045 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5046 undocumented and dangerous macro.
5047 Problem reported by Ralf Wildenhues in
5048 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5050 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5052 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5053 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5054 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5056 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5058 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5059 since evidently some packages rely on the old, broken behavior.
5060 Problem reported by Ralf Wildenhues in
5061 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5062 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5063 pre-2006-05-26 definitions, but leave in the comments that
5064 these macros are dangerous and should not be used.
5065 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5066 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5067 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5068 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5069 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5071 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5073 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5074 the use of 'tr', since this is our only use of 'tr'.
5076 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5077 and Paul Eggert <eggert@cs.ucla.edu>
5079 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5080 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5082 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5084 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5085 the output file in the `${datarootdir}' test.
5087 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5088 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5090 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5091 mention of `datarootdir' in the input file(s), but literal
5092 `${datarootdir}' in the output file, and we haven't warned yet,
5093 then warn as well: the user may have (erroneously) used
5094 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5095 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5096 * tests/torture.at (datarootdir workaround): Extend this test.
5097 * NEWS: Update.
5099 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5100 and Paul Eggert <eggert@cs.ucla.edu>
5102 * doc/autoconf.texi (autoheader Invocation): The first argument to
5103 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5104 alternatives and clear up the language a bit.
5106 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5108 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5109 ac_config_guess, ac_config_sub, ac_configure.
5110 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5111 Fix typo that prevented an unnecessary space from being removed.
5112 Problems reported by Ralf Wildenhues in:
5113 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5115 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5117 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5118 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5119 Don't use the term "thread-safe" to talk about mkdir race
5120 conditions, since the problem is more a process than a thread
5121 issue. Problem reported by Stepan Kasal in:
5122 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5123 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5124 the test for 'install' more closely. Look at MKDIR_P first.
5125 Look in the PATH, and at /opt/sfw/bin.
5126 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5127 Don't bother to try mkdir -p, since we already check mkdir --version;
5128 just look at the version number. (There's no easy way to check
5129 for race-free implementations.)
5130 * tests/tools.at (autoconf: subdirectories): Adjust to above
5131 changes, since MKDIR_P now might end in "/mkdir -p".
5133 * doc/autoconf.texi (autoheader Invocation): Mention that the
5134 first arg of AC_DEFINE_UNQUOTED must be a literal.
5135 Problem reported by Ben Pfaff in
5136 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5138 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5139 * doc/autoconf.texi (Special Chars in Variables): New section.
5140 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5141 (Installation Directory Variables): Quote $(datadir) better.
5142 (Limitations of Builtins): Describe some of eval's trickiness.
5144 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5145 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5146 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5147 in front of every arg, not just trailing args. Quote apostrophes.
5148 (_AC_EVAL_ECHO): New macro.
5149 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5150 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5151 removed.
5152 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5153 exposed by quoting of eval argument. Put the command on line line
5154 so it logs better.
5155 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5156 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5157 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5158 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5159 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5160 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5161 Use eval more safely.
5162 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5163 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5164 to be replaced.
5165 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5166 lines, exposed by quoting of eval argument.
5168 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5169 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5171 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5172 initialization of `ac_cv_exeext', do not override it if it was
5173 already set, unless it was set to `no', for compatibility with
5174 Autoconf-2.13, and comment this.
5175 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5176 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5177 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5178 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5179 Document that this test may be overridden by setting
5180 `ac_cv_exeext'.
5182 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5184 Revert these two patches:
5186 2006-04-06 Eric Blake <ebb9@byu.net>
5187 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5188 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5189 2006-04-01.
5191 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5192 Clean up _AC_COMPILER_EXEEXT* macros.
5193 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5194 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5195 ac_file to the name of the default output file and call
5196 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5197 initial `rm' of the candidate files...
5198 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5199 the same list in subsequent `rm' calls, and for the temporary
5200 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5201 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5202 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5203 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5204 no longer needed) by libtool. Make it a cache check.
5205 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5206 copied here by mistake.
5207 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5208 _AC_COMPILER_EXEEXT.
5209 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5210 _AC_COMPILER_OBJEXT directly.
5211 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5213 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5215 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5216 Fix description of how the buggy `sed' works.
5218 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5220 Sync from Automake:
5222 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5223 ENOLCK. Only mention `make -j' when applicable. Only raise
5224 fatal errors when `make -j' is involved. Improve error message.
5226 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5228 * doc/autoconf.texi (Here-Documents): We now know more about
5229 the variable expansion in here documents bug.
5230 Thanks to Tim Rice and Stepan Kasal.
5232 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5233 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5235 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5237 * tests/autotest.at (Multiline command from M4 expansion):
5238 No failure to be expected if the shell quotes newlines in
5239 commands in the `set -x' output. Report by Tim Rice.
5240 * THANKS: Update.
5242 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5244 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5245 expansion in the here-documents used by config.status, as that
5246 runs afoul of the Korn shell version M-12/28/93d bug described in
5247 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5248 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5249 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5251 2006-05-23 Jim Meyering <jim@meyering.net>
5253 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5254 Fix typo introduced with 2006-04-02 change. It reversed the sense
5255 of the test.
5257 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5259 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5260 ac_dB slightly, to save bytes in the script.
5261 Max out at 50 lines, rather than 96; this is more likely
5262 (though not guaranteed) to avoid obscure 'sed' failures.
5264 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5266 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5267 `tr -d -' as bad option argument. Work around this by deleting
5268 an unrelated character.
5269 Report by Tim Rice <tim@multitalents.net>.
5271 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5272 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5273 Stepan Kasal <kasal@ucw.cz>
5275 * doc/autoconf.texi (Particular Programs): Do not promise that
5276 we always prefer the GNU version of the program, and that we
5277 search according to PATH; both rules can have exceptions.
5278 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5279 AC_PROG_SED. Move descriptions of limitations
5280 to the Limitations of Usual Tools section.
5281 (Limitations of Usual Tools) <sed>: Mention script length
5282 limitations with Solaris /usr/ucb/sed.
5283 <grep>: Fix wording for empty alternative. Mention that -c and
5284 -l should not be combined, and that -E and -F should not be
5285 combined.
5287 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5288 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5290 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5291 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5293 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5295 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5296 AC_DEFINE is now passed to m4_pattern_allow.
5297 * NEWS: Mention that; likewise for AC_SUBST.
5298 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5299 the parameter to m4_pattern_allow.
5300 * tests/tools.at: Add a check for that.
5302 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5304 * lib/autoconf/status.m4: Fix typos.
5306 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5308 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5309 only the files that this macro generates.
5311 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5313 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5314 the HP-UX sed limitation of 99 commands, labels do not count.
5315 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5316 in the comment.
5317 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5319 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5321 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5322 Import the following fix from coreutils:
5324 2006-01-13 Jim Meyering <jim@meyering.net>
5326 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5327 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5328 not double-quote uses of that variable, to accommodate the rare
5329 case in which getmntent is available in none of the libraries
5330 checked. This happens at least on FreeBSD 5.0.
5332 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5334 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5335 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5336 some other programs unwisely rely on these undocumented vars.
5337 But put in warning comments about them.
5338 Problem reported by Ralf Wildenhues in
5339 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5340 * NEWS: Document that these variables are intended to go away.
5342 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5344 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5345 and set the language to C++ (analogous to the equivalent Fortran
5346 tests).
5348 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5349 * doc/autoconf.texi (C++ Compiler): Document it.
5350 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5351 * NEWS: Update.
5353 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5355 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5356 that caused config.status to generate 100-command sed scripts; the
5357 portable limit is 99.
5359 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5361 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5362 variable `ac_d' instead of `d' to avoid infringing namespace.
5363 Report by Ralf Menzel.
5365 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5367 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5368 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5369 * tests/tools.at (autoconf: subdirectories): New test, taken from
5370 the corresponding problem report by Ralf Wildenhues in:
5371 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5373 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5374 Quote some uses of shell variables if they might suffer unexpected
5375 globbing. This doesn't fix all instances of quoting problems that
5376 I found, just the easy ones that look safe.
5377 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5378 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5379 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5380 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5381 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5382 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5383 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5384 Likewise.
5385 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5386 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5388 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5390 * bin/autoreconf.in ($help): Reword according to the manual.
5391 Suggested by Olly Betts.
5393 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5394 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5396 * bin/autoreconf.in: Pass the directory argument to
5397 `require_configure_ac'. Fix comment.
5398 * tests/torture.at (Configuring subdirectories): Expose this.
5399 Reported by Olly Betts.
5401 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5403 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5404 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5405 Automake as follows:
5407 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5408 `$configure_in' instead of `configure.in', to preserve
5409 directory component.
5411 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5413 * config/config.guess, config/config.sub, config/texinfo.tex,
5414 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5416 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5418 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5419 test for C99 conformance; (bool) 0.5 is an integer constant
5420 expression, but (bool) -0.5 is not. Problem reported by Fedor
5421 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5423 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5425 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5426 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5427 Warn about obsolete install-sh files. Remove stray sentence
5428 fragment and fix cross reference.
5429 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5430 install -d; this undoes the 2006-05-10 change.
5431 (MKDIR_P): Mark with AN_MAKEVAR.
5432 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5433 that we don't require $INSTALL to be thread-safe. Move comments
5434 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5435 of AC_PROG_INSTALL. Output a message saying that we're checking
5436 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5437 MKDIR_P instead of AC_SUBST.
5438 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5439 Special magic for MKDIR_P, too.
5440 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5441 a dnl.
5442 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5444 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5446 Sync from Automake, as follows:
5448 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5449 * config/install-sh: Initialize IFS, so field splitting isn't
5450 turned off later.
5451 * config/mkinstalldirs: Likewise.
5452 * config/missing: Remove superfluous quotes. Replace all uses of
5453 `[' by `test', for consistency, and for..
5454 * config/missing (sed_minuso, sed_output): New variables.
5455 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5456 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5457 Fixes `missing' to detect `--output' for help2man. Fixes
5458 PR automake/483. Report by Dennis J. Linse.
5459 (autom4te): Document in `missing --help'.
5461 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5463 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5464 * config/install-sh: Don't use 'path' to talk about file names,
5465 as per GNU coding standards. Close a race condition reported by Ralf
5466 Wildenhues and Stepan Kasal. There is still a race condition
5467 on hosts that predate Posix 1003.1-1992, but we can't help this.
5468 Don't mishandle weird characters like space on pre-Posix hosts.
5469 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5470 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5471 AC_PROG_MKDIR_P from AS_MKDIR_P.
5472 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5473 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5474 earlier editions are not (including Automake 1.8.3).
5475 Do not suggest mkinstalldirs for thread-safety.
5476 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5477 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5478 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5479 presence of special characters and race conditions.
5480 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5481 in Autoconf's name space.
5483 2006-05-10 Bruno Haible <bruno@clisp.org>
5484 and Paul Eggert <eggert@cs.ucla.edu>
5486 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5487 from Automake with minor changes.
5488 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5490 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5492 * config/install-sh: Update to Automake CVS version, as follows:
5493 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5494 * lib/install-sh: Simplify the expr implementation of dirname.
5495 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5496 * lib/install-sh: Handle --, and diagnose unknown options.
5498 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5500 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5501 `./autom4te' to create `./testsuite', since the `all' target
5502 will ensure its presence, but `installcheck' should not create
5503 the uninstalled wrappers.
5505 * tests/torture.at (Unusual Automake input files): Skip if we
5506 detect automake < 1.8.
5508 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5510 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5511 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5512 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5513 * NEWS: Update.
5515 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5517 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5518 munge (multiple) white space and other oddities.
5519 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5520 single quotes in variable assignment.
5521 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5522 and similar failures by adding multiple spaces, tabs, and other
5523 special characters.
5524 Report and different test suggested by Francesco Romani
5525 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5527 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5528 single quotes, we only need to search for single quotes; this
5529 both simplifies the search pattern, and makes us less
5530 susceptible to `echo' variations for arguments not containing
5531 single quotes.
5532 (_AC_ARG_VAR_VALIDATE): Likewise.
5534 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5536 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5537 `$*' and IFS concatenation issue with traditional shells and
5538 bash-2.04. Report by Seanster@Seanster.com.
5540 2006-05-03 Bruno Haible <bruno@clisp.org>
5542 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5543 precisely which Mac OS X versions have the od problem.
5545 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5547 * doc/autoconf.texi: Use @option systematically.
5549 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5550 and Bruno Haible <bruno@clisp.org>
5552 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5553 about 'od'.
5554 (Integer Overflow): Mention the special case of integer division
5555 overflow.
5557 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5559 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5560 traditional shells like the Solaris one that do not use the
5561 first IFS character for assembling `$*'.

5620 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5622 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5623 since as_me isn't set yet.
5625 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5627 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5628 a few minor bugs in this area.
5630 * doc/autoconf.texi (Programming in M4sh): Comment out the
5631 documentation of AS_BASENAME, for now.
5632 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5633 (Limitations of Builtins) <basename>: Do not refer to

5635 * bin/autoconf.as (me): Don't use AS_BASENAME.
5636 (dir): Remove the unused variable.
5637 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from

5657 * lib/autoconf/general.m4: Likewise.
5658 * lib/autoconf/headers.m4: Likewise.
5660 * doc/autoconf.texi (Run Time): Document the exit status situation

5663 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5665 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5666 Archive is not officially `GNU' any more. Update URL.
5667 (Defining Directories): Likewise
5668 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5670 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5672 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5673 newline from the `trap' code to finish `config.log'; the NetBSD
5674 /bin/sh resets the exit status after an empty command, as
5675 documented in doc/autoconf.texi.
5676 Reported by Dalibor Topic <robilad@kaffe.org>.
5678 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5680 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5681 Suggested by Bruno Haible.
5683 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5685 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5686 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5687 Instead, just list the shells that we know work.
5688 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5689 changed. Be more cautious about the _cv_ variable.
5690 * tests/tools.at (Syntax of the shell scripts): Check the
5691 _cv_ variable once, at first, to avoid an internal autoconf error
5692 when sh -n does not work.
5694 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5696 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5698 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5700 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5701 use ">&-" since we're only 99.999% sure that this is portable,
5702 and since the MinGW bug is fixed in a different way.
5703 * lib/autotest/general.m4 (AT_INIT): Likewise.
5705 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5707 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5708 before opening config.log, to avoid hitting a bug on MinGW.
5710 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5712 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5713 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5714 This works around a MinGW bug reported by Eric Paire.
5715 Make sure that all writes to the log file append to it,
5716 rather than possibly losing data.
5717 * lib/autotest/general.m4 (AT_INIT): Likewise.
5719 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5721 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5722 description.
5724 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5726 * NEWS: Update.
5728 * configure.ac (AC_INIT): Bump to 2.59d.
5730 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5732 Version 2.59c.
5734 * Makefile.maint (news-date-check): Do not require a leading `*'
5735 before the release date in NEWS.
5737 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5738 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5740 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5741 the instantiated file do not contain the string 'datarootdir'
5742 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5743 @mandir@, replace the reference '${datarootdir}' by the value.
5744 * tests/torture.at (datarootdir workaround): New test.
5745 * NEWS: Advertise this temporary fixup.
5746 Based on a patch by Bruno Haible, reported and analyzed by
5747 Paul Eggert and Noah Misch.
5749 2006-04-12 Eric Blake <ebb9@byu.net>
5751 * tests/autotest.at (Debugging a failed test): Fix comment.
5753 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5755 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5756 all the changes since 2006-04-07.
5758 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5760 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5761 succeeded, but `ln -s file dir' failed, take care to remove the
5762 leftover target before the next test, to prevent its spurious
5763 failure; also make sure `ln file dir' works before selecting it.
5764 Thanks to Keith Marshall for pointing this out.
5765 * THANKS: Update.
5767 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5768 assignments in `at_debug_args', so that we put them correctly
5769 in the `run' script.
5770 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5771 Reported by Eric Blake.
5773 2006-04-11 Eric Blake <ebb9@byu.net>
5775 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5776 top-level tests after micro-suite has been run. Used in...
5777 (Debugging a successful test, Debugging script and environment),
5778 (Debugging a failed test): ...these new tests. The first of these
5779 is fixed by...
5780 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5781 macro, split out from...
5782 (AT_INIT): ...here, so that using -d also generates a run script.
5783 Document that -d inhibits top-level logging.
5784 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5785 inhibits top-level logging; debug scripts are created.
5787 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5788 check.
5789 * tests/autotest.at (Empty test, Empty check): New test to check it.
5791 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5792 from gcc.
5794 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5796 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5797 the files if a problem appears. Make the empty *.at files
5798 read-only, too. Proposed by Ralf Wildenhues.
5800 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5802 * config/Makefile.am: Add comment to force updated Makefile.in.
5804 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5805 space only patch to this file, this patch causes the Makefile.in
5806 files that include freeze.mk to be updated, and thus have a
5807 newer time stamp again, which in turn makes a pristine CVS
5808 checkout have correct time stamps.
5810 * Makefile.maint (cvs-sv): New macro, to be used..
5811 (config.guess-url_prefix, config.sub-url_prefix)
5812 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5813 point to CVS text checkout of Gnulib files.
5814 (copyright-check): Bump current year.
5815 (announcement): Do not hard-wire `./announce-gen'.
5816 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5817 correctly.
5818 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5819 `chmod +x'.
5820 (wget_files): Update config.guess, config.sub, texinfo.tex by
5821 `wget-update', now that their URLs work again.
5823 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5825 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5826 Problem noted by Paul D. Smith.
5828 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5830 * doc/autoconf.texi: Remove unused words from word list.
5831 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5832 .x-sc_trailing_space: New files.
5834 * doc/standards.texi: Sync from gnulib.
5836 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5837 `LIBOBJDIR' as experimental.
5839 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5840 with a target directory; it's internally implemented as `cp'
5841 anyway, but since Autoconf advertises the possibility to use
5842 a target directory when LN_S is `ln -s', we need to find out.
5843 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5844 analyzed by Keith Marshall <keith.marshall@total.com>.
5846 * THANKS: Update.
5848 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5850 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5851 confdefs.h as-is. In general, if it has backslash-newline or the
5852 like, then it doesn't work either to sort or to remove empty
5853 lines.
5855 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5857 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5859 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5861 * lib/autom4te.in (Automake-preselections): Preselect
5862 _AM_SUBST_NOTMAKE.
5864 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5866 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5867 apostrophe within a single-quoted string, as this is the usual
5868 tradition and is easier to read than '"'"'. Don't rely on the
5869 shell treating "$/" like '$/'. Use a more-consistent indenting
5870 style for the trap.
5872 2006-04-09 Eric Blake <ebb9@byu.net>
5874 * tests/autotest.at (Backquote command substitution),
5875 (Multiline backquote command substitution): Remove mistaken
5876 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5877 applied...
5878 (Parenthetical command substitution, Multiline parenthetical
5879 command substitution): here.
5881 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5883 Import macros from gnulib (often changing their name).

5899 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
5900 Gnulib section.
5901 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,

5905 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
5906 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

5911 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
5912 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
5913 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
5914 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
5915 (C Compiler): Move AC_C_LONG_DOUBLE to ...
5916 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
5917 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
5918 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
5919 (Coding Style). Don't mention m4_expand_once.
5920 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

5928 (AC_HEADER_ASSERT): New macro.
5929 (AC_HEADER_STDBOOL): Don't assume "#error" works.
5930 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
5931 Catch a bug in an HP-UX C compiler.
5932 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
5933 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

5937 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
5938 New macros.
5940 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
5941 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
5943 2006-04-08 Stepan Kasal <kasal@ucw.cz>
5945 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
5946 of the warning introduced by the 2001-08-28 change.
5948 2006-04-08 Stepan Kasal <kasal@ucw.cz>,

5951 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
5952 variables shall be overriden by the cache.
5953 * tests/torture.at (AC_ARG_VAR): Test also with a first value
5954 that contains braces.
5956 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5958 Revert the patch from 2006-04-01 and only improve
5959 _AS_DETECT_BETTER_SHELL:
5961 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
5962 skip nonexistent directories.
5963 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
5964 only shell candidates which exist.
5965 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
5966 * lib/autotest/general.m4 (AT_INIT): No need to give three

6012 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6014 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6015 whether `set' quotes correctly: redirect stderr of the tested
6016 `set', and use a subshell, for Ultrix; use `sed' instead of
6017 `grep' for zsh `set' which may write binary output; match only
6018 at the beginning of a line, to avoid false positives.
6019 In order to avoid false positives by unrelated variables with
6020 multiline content, put the dump algorithm in a subshell and
6021 unset all variables containing newlines (except some which are
6022 special to the shell). Warn about cache variables that are
6023 unset.
6025 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6027 * config/config.guess, config/config.sub, config/texinfo.tex:
6028 Sync from upstream.
6030 * tests/mktests.sh: Reword comments.
6032 * tests/mktests.sh: Only skip internal macros starting with
6033 `_AC_' or `__AC_'. Noted by Stepan Kasal.
6034 Update exclusion lists for the test suite to this end:
6035 (AC_ARG_VAR): Do test this now.
6036 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6037 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6038 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6039 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6041 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6042 shell issue with double-quoted command substitutions of native
6043 commands.
6044 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
6045 Marshall.
6047 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

6059 * lib/autoconf/status.m4: More replacements to
6060 <tab><space> where this makes sense.
6062 2006-04-06 Stepan Kasal <kasal@ucw.cz>

6065 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6067 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6068 ac_config_<foo>s again, sometimes normalized, sometimes not.
6069 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6070 (AC_CONFIG_COMMANDS): Do not do so here.
6071 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6072 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6073 2005-07-25 rewrite. Noticed by Noah Misch.
6075 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6076 _AC_PRESERVE_HELP_ORDER, ...
6077 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6079 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
6080 inside m4_expand_once; it is redundant.
6082 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6083 for --help from Cygnus `configure.'
6085 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
6087 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
6088 on a patch proposed by Ralf Wildenhues.

6100 * doc/autoconf.texi (Help Formatting): New node.
6101 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
6103 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6105 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
6106 lib/autoconf/specific.m4, lib/autoconf/status.m4,
6107 lib/autoconf/types.m4, lib/autotest/general.m4,
6108 tests/mktests.sh, tests/torture.at: White space cleanup:
6109 remove some SPACE before TAB, or add quoting ('' or @&t@).
6111 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
6113 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
6115 2006-04-05 Eric Blake <ebb9@byu.net>
6117 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
6118 empty test suite works.
6119 * tests/autotest.at (Empty test suite): Remove xfail.
6121 2006-04-05 Noah Misch <noah@cs.caltech.edu>

6124 TAGS to ac_config_<foo>s.
6125 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
6126 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
6127 normalizing it, consistent it with previous releases.
6128 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
6130 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6132 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
6133 Use simplified args that Eric Blake originally suggested.
6135 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6137 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6138 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6139 Use 'comm' rather than N instances of grep; this also fixes a bug
6140 whereby substrings were incorrectly matched, causing us to not
6141 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6142 (exclude_list): Exclude empty macros.
6143 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
6145 Use awk rather than grep -E or egrep, to avoid
6146 portability problems with regular expressions containing newlines.

6148 Switch from grep to awk syntax.
6149 (ac_exclude_script): Renamed from ac_exclude_egrep.
6150 (au_exclude_script): Renamed from au_exclude_egrep.
6152 2006-04-04 Noah Misch <noah@cs.caltech.edu>
6154 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
6155 a subdirectory subject to Cygnus `configure'.
6156 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
6158 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
6159 report request when we have no AC_PACKAGE_BUGREPORT.
6161 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6163 * THANKS: Update.

6166 generated files.
6168 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
6169 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
6170 typedef'ed restricted pointer, to catch a compiler bug on
6171 HP-UX 11.x, and fix warnings so it passes with -Werror.
6172 (_AC_PROG_CC_C99): Likewise.
6173 Reported by Albert Chin <china@thewrittenword.com>.
6174 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

6189 * THANKS: Add myself.
6191 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6193 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
6194 to log, point to testsuite output tree.
6196 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>

6224 Clean up _AC_COMPILER_EXEEXT* macros.
6226 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6227 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6228 ac_file to the name of the default output file and call
6229 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6230 initial `rm' of the candidate files...
6231 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6232 the same list in subsequent `rm' calls, and for the temporary
6233 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6234 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6235 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6236 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6237 no longer needed) by libtool. Make it a cache check.
6238 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6239 copied here by mistake.
6240 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6241 _AC_COMPILER_EXEEXT.
6242 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6243 _AC_COMPILER_OBJEXT directly.

6274 * lib/autoconf/general.m4 (_AC_INIT_VERSION): Emit script name and
6275 Autoconf version number despite a zero- or one-argument AC_INIT.
6277 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
6278 subordinate tools.
6279 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
6280 * doc/autoconf.texi (autoreconf Invocation): Document it.
6282 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
6283 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

6289 rm failed to remove it.
6291 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6293 * bin/autoupdate.in: Redefine m4_location so that warnings print
6294 the correct lines of the input file by subtracting..
6295 (_au__first_line): ..this new definition.
6297 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
6298 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
6299 Remove stray newline in output.
6300 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
6301 AC_DEFUN this for autoconf, including the obsoletion diagnose.

6303 m4sugar macros.
6304 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.

6308 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
6309 hairy details.
6310 The AC_LANG_SAVE issue was reported against Libtool by
6311 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
6312 Kristian Kvilekval <kris@cs.ucsb.edu>.
6314 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6316 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
6317 switch all of them on and of when necessary. Fixes the bug when
6318 m4sugar macros (e.g., m4_define) were expanded after the first
6319 automatic update (e.g., after AC_PREREQ or AC_INIT).

6352 (File System Conventions): Put discussion of // versus / here, and
6353 modernize it a bit.

6366 2006-03-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6368 * bin/autoscan.in: The value of find_configure_ac should be
6369 checked for existence, so we don't barf over a nonexisting
6370 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
6372 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6374 * bin/autoupdate.in: Fix some typos.
6376 2006-03-21 Stepan Kasal <kasal@ucw.cz>
6378 * doc/autoconf.texi (Installation Directory Variables): Fix typo.

6435 that the same works when cross-compiling.
6436 * tests/semantics.at (AC_CHECK_ALIGNOF, AC_CHECK_ALIGNOF struct):
6437 (AC_CHECK_SIZEOF, AC_CHECK_SIZEOF struct): Use it.

6923 posix' unconditionally, for pdksh in `native sh' emulation.
6925 2005-12-01 Paul Eggert <eggert@cs.ucla.edu>
6927 * doc/autoconf.texi (Shellology): Document eval $? problem
6928 with ash.
6929 (Limitations of Builtins): Likewise.
6931 2005-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6933 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Pass
6934 CONFIG_SHELL in the environment of the configure rerun.
6935 * doc/autoconf.texi (Here-Documents, config.status Invocation):
6936 Suggest passing CONFIG_SHELL absolute, and in the environment
6937 rather than as option.
6939 2005-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6941 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
6942 Fix quoting of output line (triggered for many AC_SUBST_FILEs).
6943 Fix macro quoting. Fix output for n * 98 substituted variables.
6945 2005-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6947 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Initialize
6948 `tmp' to avoid file removal race.
6950 2005-11-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6952 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
6953 ac_clean_files and LIBOBJS.
6955 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6957 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
6958 Factor functionality to..
6959 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
6960 `AC_SUBST($1)' in the public version.
6961 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
6962 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
6963 ac_pt_* variables.
6965 2005-11-01 Stepan Kasal <kasal@ucw.cz>
6967 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
6968 filesystems.
6970 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6972 * NEWS: Move AH_HEADER mention to right place.
6974 2005-10-27 Stepan Kasal <kasal@ucw.cz>
6976 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
6977 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
6979 2005-10-25 Stepan Kasal <kasal@ucw.cz>
6981 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
6982 conftst2.$ac_objext.
6983 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
6985 2005-10-24 Stepan Kasal <kasal@ucw.cz>
6987 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
6988 conftest.o, to see whether the compiler really obeys; rm the object
6989 file before and after the test and register it with ac_clean_files.
6990 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
6992 2005-10-21 Stepan Kasal <kasal@ucw.cz>
6994 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
6995 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
6996 code so that the most common case requires less forks.
6998 2005-10-20 Stepan Kasal <kasal@ucw.cz>
7000 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
7001 not portable; thanks to Paul Eggert and Alexandre.
7003 * NEWS: Fix an old typo.
7005 2005-10-20 Jim Meyering <jim@meyering.net>
7007 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
7008 the latter'', in two places.
7010 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
7012 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
7013 AC_LANG_PROGRAM, fixing a typo. Don't give details about
7014 the inner workings of AC_LANG_FUNC_LINK_TRY.
7015 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7016 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7017 by the function rather than ignoring it.
7018 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7019 comparing its address. Intel's interprocedural optimization was
7020 outsmarting the old heuristic. Problem reported by
7021 Mikulas Patocka.
7023 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7025 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
7027 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
7029 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

7032 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7034 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7035 before removing it (chmod -R u+rwx); there are three instances of this.
7037 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7038 Stepan Kasal <kasal@ucw.cz>
7040 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7041 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7042 make its content writable before removing it. Remove an errorneous
7043 comment from the end, where the logs of the failed tests are copied
7044 to the main log file.
7046 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7048 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7049 in case the computer is too quick. Double quote the configure.ac
7050 snippets.
7052 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7053 problems if the testsuite were running too fast.
7055 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7057 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7058 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7059 (which belong to Xt, not X itself). See Debian bug 327655.
7060 * NEWS: Mention this.
7062 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7064 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7066 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7068 * config/move-if-change: Don't output "$2 is unchanged";
7069 suggested by Ben Elliston. Handle weird characters correctly.
7071 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7073 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7074 calls, so that the final expansion of this macro is shorter.
7075 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7076 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7077 the cleanup there. Use AS_VAR_* macros, to be more general.
7078 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7080 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7082 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7084 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7086 * doc/autoconf.texi (Configuration Headers): Add an index entry
7087 for AH_HEADER.
7089 2005-08-26 Pavel Roskin <proski@gnu.org>
7091 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
7092 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7093 running xmkmf.
7095 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7097 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7098 The previous patch didn't work, so try a better one.
7100 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7102 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7103 in the example. Reported by Bruno Haible.
7104 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7105 "if $undefined_var;" succeeds with my shell.
7107 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7108 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7109 but change the m4_divert_text to m4_divert_once.
7111 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7113 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7114 Work around bug in Solaris /usr/xpg4/bin/awk.
7115 The bug is present in at least Solaris 8 through 10.
7117 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7119 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7120 some evil values and relying on the fact that $* concatenates the
7121 parameters by the first character from IFS.
7123 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7124 Stepan Kasal <kasal@ucw.cz>
7126 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7127 first header appears, define AH_HEADER.
7128 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7129 Update limitations about when to call AC_CONFIG_HEADERS.
7130 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7131 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7132 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7133 ``Configuration Actions''; fix their index entries.
7135 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7136 options correctly. Process N-M as M-N if M is smaller than N.
7137 Process ranges correctly so that N-N will run only N.
7138 Sort and uniquify the tests that will be run. If there is more
7139 than one test, reinsert the banners for the tests.
7140 * tests/autotest.at (Keywords): Unmark XFAIL.
7142 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7144 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7145 before passing the macro name to AH_TEMPLATE.
7147 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7148 now opens log after option processing; in particular, --version
7149 and --help do not touch config.log.
7151 * Makefile.maint: Revert the change from 2005-08-12.
7153 2005-08-22 Stepan Kasal <kasal@ucw.cz>
7155 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
7156 common code to...
7157 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
7159 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7161 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7162 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7163 Language cleanup.
7165 * doc/autoconf.texi (Defining Symbols, Changed Results):
7166 Prepend to LIBS, not append, in examples.
7168 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7170 When building in place, set srcdir="."; suggested by Tim Van Holder.
7172 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7173 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7174 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7175 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7176 does not mean "no --srcdir option".
7178 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7180 * tests/autoscan.at (autoscan): New file.
7181 * tests/suite.at: Use it.
7182 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7183 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7185 * tests/autotest.at (Keywords): Test keywords combinations.
7187 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7189 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7190 add "2>&1"; gzip 1.2.4 prints help on stderr.
7192 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7194 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7195 was pushdef'ed twice while popped only once. Push it only once.
7196 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7198 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7200 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
7201 prefixed by mere "===", not "configure: === ".
7203 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
7205 * Makefile.maint: Update from Bison.
7207 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7208 "<tab>" in comment, so that the point is understandable.
7210 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7212 Rewrite substantial part of lib/autoconf/status.m4.
7213 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7214 and CONFIG_COMMANDS are not processed in four separate loops.
7215 Instead, there is one main loop. This alows that the common code
7216 is expanded only once, thus config.status (and configure) is smaller.
7218 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7219 the AC_LIST_FILES and cousins macros are no longer used.
7221 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7222 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7223 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7224 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7225 contain the initialization, nor the for loop, nor the associated
7226 commands; all these go to ...
7227 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7228 _AC_OUTPUT_CONFIG_STATUS.
7229 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7230 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7231 (_AC_OUTPUT_FILE): The creation of the sed script ...
7232 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7233 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7234 _AC_OUTPUT_MAIN_LOOP.
7235 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7236 _AC_CONFIG_COMMANDS): Use ...
7237 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7238 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7239 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7240 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7241 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7242 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7243 ... new macros.
7244 (_AC_CONFIG_UNIQUE): Update.
7245 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7246 Replaced by this ...
7247 (_AC_LIST_TAGS): ... new common macro.
7248 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7249 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7250 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7251 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7252 this didn't belong to the `config commands' section.
7253 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7254 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7255 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7256 to the `config commands' section either.
7257 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7258 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7260 ... and many changes to the comments nearby.
7262 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7263 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7264 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7265 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7266 (#define header templates): The comment at the top of the generated
7267 header now includes the name(s) of the source file(s).
7269 Several unrelated small changes:
7271 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7272 parameter to AC_DIAGNOSE.
7273 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7274 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7275 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7276 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7277 with AU::AC_OUTPUT.
7278 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7279 in AC_OUTPUT doesn't double-quote it either.
7280 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7281 parameters.
7283 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7285 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7286 versions of Portland Group compiler produce single- and double-quoted
7287 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7288 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7290 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7292 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7293 This is a corrected version of yesterday's patch.
7295 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7297 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
7298 path, too; insert a "===" to emphasize the line.
7300 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
7301 ac_cv_build_alias to ac_build_alias.
7302 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7304 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7305 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7306 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7307 (AC_ARG_VAR): ... here.
7308 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7309 target_alias.
7311 Keep a list of all precious variables and process them with one simple
7312 for loop, instead of expanding all commands, or, OTOH, complicated
7313 processing of output of "set".
7314 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
7315 variable names in new macro...
7316 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
7317 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
7318 a loop to assign all ac_env_* and ac_cv_env_* variables.
7319 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7320 to INIT_PREPARE.
7321 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7322 its value to shell variable ac_precious_vars and call
7323 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
7324 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
7325 _AC_ARG_VAR_VALIDATE.
7327 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
7328 and the AC_SUBSTs ...
7329 (AC_INIT): ... here.
7331 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
7332 the ac_subst_files section in config.log.
7334 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
7336 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

7340 * lib/autoconf/c.m4 (AC_C_TYPEOF): New macro.
7341 * tests/c.at (C keywords): Test AC_C_TYPEOF.
7343 Fix problems reported by Nicolas Joly.
7344 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
7345 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7346 They are generated by the Tru64 v5.1B shell.
7348 2005-07-05 Stepan Kasal <kasal@ucw.cz>
7350 Fix my changes from 2005-07-01; reported by Noah Misch.
7351 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
7352 description, the macro now accepts only a single tag.
7353 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
7355 Fix cases when the varsions of Autoconf and Autotest don't match.
7356 Reported by Noah Misch.
7357 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
7358 at_top_builddir, for compatibility with older autotest.
7359 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
7360 is not set, use at_top_builddir, for compatibility with older
7361 versions of autoconf.
7363 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7365 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
7366 Problem reported by Patrick Welche.
7368 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
7370 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7371 sed substitution command, so that we allow | in program prefixes
7372 and program suffixes. (& is a problem anyway; we're not fixing
7373 that here.)
7374 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
7375 configure_input, top_builddir, srcdir, etc.
7376 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7377 PATH_SEPARATOR in AUTOTEST_PATH.

7387 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

7405 about #include <config.h>.
7406 (Generic Functions): Mention the Gnulib project.
7407 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
7409 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
7410 document to output the default config_* lists to config.status.
7411 Don't recognize option --file, if the functionality is not there.
7412 Likewise for --header; moreover, recognize --he and --h as shortcuts
7413 for --help in that case.
7415 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7416 matches the order of execution. No code changed.

7438 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7439 (AC_SUBST): Call it.
7440 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7441 the directory specific variables; but don't call it for configure_input.
7443 2005-06-28 Derek Price <derek@ximbiot.com>
7445 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7446 addition.
7448 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7450 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
7451 directory have inherent problems with special characters like spaces,
7452 due to limitations in Make syntax. Problem reported by Alexandre
7453 Duret-Lutz.
7454 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
7455 Also, fix Tru64 porting problem with shell patterns,

7467 from Justace Clutter.
7468 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7469 variable into diagnostic. Make the diagnostic an error, not a warning,
7470 because we really don't support spaces and suchlike in dir names.
7471 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7472 Don't worry about backslashes in srcdir; it can't happen now.
7473 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
7474 Simplify ac_optarg handling.
7475 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

7485 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
7486 that '\|' is not allowed in BREs; recommend using newline separated
7487 list of patterns instead of multiple -e options.
7489 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
7491 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

7495 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
7497 2005-06-21 Stepan Kasal <kasal@ucw.cz>
7499 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
7500 b, t, r, w commands require single space, while : cannot have any.
7501 (Special Shell Variables): Fix sed code this in the example.
7502 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7503 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
7505 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
7506 expand to the empty list. Don't use two pairs of m4_changequote,
7507 it's not necessary.
7509 2005-06-20 Derek Price <derek@ximbiot.com>
7511 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
7513 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
7515 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
7516 * doc/autoconf.texi:
7517 Don't mention Solaris versions so much, if a
7518 problem is common to all extant versions of Solaris. Say "SunOS
7519 4" instead of "SunOS" for SunOS 4.
7520 (awk): Mention more of the limitations of traditional Awk.
7521 (cat): Don't talk about cat -v.
7523 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
7525 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
7526 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

7528 to be compatible with glibc strverscmp.
7529 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
7531 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
7532 on Mac OS X 10.4 reported by Peter O'Gorman in:
7533 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
7534 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
7535 Use shell builtins rather than 'expr', to work around expr bug.
7537 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
7539 * doc/autoconf.texi: "filesystem" -> "file system".
7540 "behaviour" -> "behavior".

7542 * lib/autoconf/general.m4: Omit blank after ":" sed command,
7543 as per POSIX.
7544 * lib/m4sugar/m4sh.m4: Likewise.
7545 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
7546 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
7548 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
7549 (.x.1): Ignore the time stamp in the .TH line when deciding whether
7550 to update the man page. That way, we don't have to check in new
7551 man pages every month.
7553 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
7554 quotes and backslashes. Patch from Derek Price.

7559 AS_TR_SH.
7561 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
7563 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7564 -u, since it outputs chatter if the input files are the same.
7565 Problem reported by Ralf Menzel.
7567 2005-06-08 Derek Price <derek@ximbiot.com>
7569 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7570 renaming them since they are about to be redefined anyhow.
7572 2005-06-08 Derek Price <derek@ximbiot.com>
7574 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7575 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7576 Move m4_undefine to alphabetical order.
7578 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
7580 * README: Recommend GNU M4 1.4.3 or later.
7581 * doc/autoconf.texi (Introduction): Likewise.
7582 Reword to avoid some formatting glitches.
7583 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7584 Clarify explanation of HP compiler bug.
7585 Redo example output tp match current CVS snapshot.
7586 Use @example.org in email addresses when the examples
7587 might get inadvertently cut-and-pasted into user code.
7588 Remove example of autom4te usage that doesn't seem to work now.
7589 Use modern AC_INIT (except when the example is meant to be
7590 shown with Autoconf 2.13).
7591 Update ksh info for Solaris 9 and later.
7592 KB -> kB.
7593 Modernize description of Automake versions a bit.
7594 Don't claim a future version of Autoconf is near.
7595 * doc/install.texi: Reword to avoid some formatting glitches.
7597 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7599 * doc/autoconf.texi: Add [] to examples, so that the manual
7600 follows its own advice about quoting better.
7601 Reword to avoid some formatting glitches.
7602 * doc/installt.exi: Reword to avoid some formatting glitches.
7604 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7605 Tru64 ksh pattern matching bug. Reported against Libtool by
7606 Albert Chin <libtool@mlists.thewrittenword.com> and
7607 Nicolas Joly <njoly@pasteur.fr>.
7609 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7611 m4_cdr of one-member list was [[]] (one-member list containing an
7612 empty string) instead of [] (an empty list. Callers were skewed to
7613 match this misbehaviour. As a consequence of this:
7614 - m4_foreach([x], [], [foo]) expanded to `foo', while
7615 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7616 This bug has been fixed:
7618 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7619 expand to an empty string; print error msg if called without
7620 an argument list.
7621 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7622 misbehaviour; handle [] and [[]] correctly.
7624 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7626 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

7628 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
7630 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7632 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7633 swallow records with more than 99 fields.
7634 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7635 parse the long line.
7637 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7639 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7640 swallow literals longer than 399. Reported by Ralf Wildenhues.
7641 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

7644 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
7646 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7647 to gfortran, and make these the first two compiler names
7648 checked (following the general autoconf preference for gcc).
7650 2005-06-03 Stepan Kasal <kasal@ucw.cz>
7652 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7653 (DISTCLEANFILES): Remove $(check_SCRIPTS).
7654 (testsuite): Make sure autotest.m4f is up-to-date before using it.
7656 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
7658 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7659 expression of unbounded size when processing the --list
7660 option. This runs afoul of a limit of 399 bytes per regular
7661 expression on AIX. Problem reported by Ralf Wildenhues.
7663 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

7666 * doc/autoconf.texi (Particular Headers): Reword example
7667 for multiline stdbool replacement.
7668 (Setting Output Variables): Reword text a bit. Don't
7669 give all the details about |#_!!_#|.
7670 Reword description of line replacement.
7672 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7674 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7675 now contain newlines, and substituted files must be referenced on
7676 a line alone; the sed scripts to substitute them are now very
7677 different.
7678 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
7679 commands can be put in a sed script portably.
7680 * doc/autoconf.texi (Setting Output Variables): Document above
7681 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
7682 use of multiline substitution.

7692 * tests/local.at: Don't attempt to check for negated character
7693 classes in shell scripts. The test was too brittle.
7695 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7697 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
7698 * doc/autoconf.texi (Limitations of Builtins): Document this
7699 limitation.
7701 2005-05-24 Stepan Kasal <kasal@ucw.cz>
7703 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
7704 common code; used in many places in the tree.

7711 messages when ac_unique_file is not found.
7712 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7713 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
7714 commands, for consistency with AC_MSG_ERROR and such.
7716 * bin/autoconf.as: Make more use of "shift 2" in option processing.
7718 * bin/Makefile.am: Merge the two rules for creating scripts.

7726 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7728 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
7729 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7730 (ac_top_builddir): ... this ...
7731 (ac_top_build_prefix): ... to this; the old name is also kept, for
7732 backward compatibility.
7733 (ac_top_builddir_sub): New variable, without the trailing slash,
7734 always nonempty.
7735 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
7736 * doc/autoconf.texi (Configuration Actions): Rename
7737 ac_top_builddir to ac_top_build_prefix.
7738 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
7739 at_top_builddir to at_top_build_prefix.

7747 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7749 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7750 argument to m4_foreach. I guess it was necessary in the past,
7751 but I think it's a no-op now.
7753 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7755 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7756 ``cat <<_ACEOF'' commands to one.
7757 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
7758 * lib/autoconf/status.m4: On various places, use expr instead of
7759 ``echo|sed.''
7760 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
7761 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
7762 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7763 a range.
7764 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
7765 the wrong patterns between ``case'' and ``esac.'' The previous
7766 code had false positives.
7768 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
7770 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
7771 as on 2005-05-02.
7772 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
7773 Mention LIBOBJDIR.

7828 for absolute directory names in one loop.
7829 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
7830 abbreviations of --version and --debug.
7832 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
7834 * doc/autoconf.texi (Autoconf Language): Be more precise about
7835 quoting rules. Problems noted by Stepan Kasal.
7836 Also, throughout this document, be more careful about white space.
7837 "blank", "white space", and "space" all have different meanings
7838 and we should be careful to say what we mean.
7840 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
7842 Fix C++ related problems reported by Werner Lemberg.

7858 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
7859 set by latest automake.
7861 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7863 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
7864 outputs 0 on GNU/Linux these days.
7866 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
7868 * doc/autoconf.texi (Autoconf Language): Add more description
7869 about quoting heuristics.
7870 (Limitations of Builtins): Describe "set -" problems.
7872 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7874 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
7875 not newline.
7877 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
7878 by AC_DEFINE; it was a mistake.
7879 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
7881 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7883 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7885 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7887 * doc/autoconf.texi (External Software): Quadrigraphs are not
7888 processed correctly in AS_HELP_STRING; avoid this in the examples.
7889 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7890 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7891 comment and reduce m4_default([foo], []) to [foo].
7892 (m4_strip): Update the explanation.
7894 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7896 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7897 Remove core.conftest.* too; it's generated by Tru64 5.1.
7898 Problem reported by Jennis Pruett.
7899 * lib/autoconf/functions.m4
7900 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7901 Don't bother to remove core files; AC_RUN_IFELSE should do that
7902 for you.
7904 2005-04-19 Stepan Kasal <kasal@ucw.cz>
7906 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

7946 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7948 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
7949 Merge `-z option' as well for the benefit of Solaris link flags. Pass
7950 whole-archive (-zallextract, -zdefaultextract) options in the hope of
7951 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
7952 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
7954 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
7956 * NEWS: The configure command now warns you if you attempt to use
7957 a directory whose name contains a special character like space,
7958 newline, or "\".
7959 * doc/autoconf.texi (Installation Directory Variables): Allow
7960 "," in file names. Do not use \@; it's not a portable regexp.
7961 * bin/Makefile.am (edit): Likewise.
7962 * lib/Makefile.am (edit): Likewise.
7963 * tests/Makefile.am (edit): Likewise.
7964 * tests/semantics.at: Likewise.

7969 unportable file names.
7970 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
7971 (AC_INIT): Use it.
7972 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
7973 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
7974 ac_pwd, and quote srcdir.
7975 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
7977 * doc/autoconf.texi: Fix some systematic formatting problems.
7978 ".)" needs a following @: if not at the end of a sentence, and
7979 similarly for "!)". "etc." should be preceded by a comma.
7980 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
7982 2005-03-22 Bruno Haible <bruno@clisp.org>
7984 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
7985 argument is often called 'build-aux'.
7987 2005-03-07 Stepan Kasal <kasal@ucw.cz>
7989 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
7990 macro AC_TRY_LINK is obsolete.
7991 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
7992 `AC_CONFIG_FILES'.
7994 2005-02-24 Stepan Kasal <kasal@ucw.cz>
7996 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
7997 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
7998 from a Common Lisp's `cl'.
7999 (AC_PROG_CXX): Behave according to the documentation: don't
8000 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8001 make the variable CCC precious; use `cl.exe', not `cl'.
8003 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8004 Alexandre Duret-Lutz <adl@gnu.org>
8006 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8007 /dev/null, as "configure" shouldn't read stdin, and this insulates
8008 us from problems (e.g., when testing for "cl"). Also, do this
8009 redirection before invoking "hostname" or "uname", and keep the
8010 original input stream available via...
8011 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8012 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8013 bother with "</dev/null" since it's now done at the top of
8014 'configure'.
8015 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8016 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

8022 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8024 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8025 newline if neither \c nor -n work, as that would output two
8026 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8028 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8030 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8031 This causes that any required macros inside will get before the if.
8032 * doc/autoconf.texi (autom4te.cache): A typo.
8034 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8036 Undo previous change, except keep the change to
8037 lib/autoconf/programs.m4 that replaced grep with shell
8038 pattern-matching. This is because net-snmp configure reads stdin.
8039 Reported by Noah Misch.
8041 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8043 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8044 from /dev/null, as "configure" shouldn't read stdin, and this
8045 insulates us from problems (e.g., when testing for "cl").
8046 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8047 before invoking "hostname" or "uname".
8048 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8049 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8050 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8051 "</dev/null" since it's now done at the top of 'configure'.
8052 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8053 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8054 Also, replace grep with shell pattern-matching, to save a process.
8056 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8058 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8059 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8060 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8061 compiler.
8063 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8065 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8066 grep -q isn't portable. Improve grep -s explanation.
8067 Problem reported by Dan Manthey.
8069 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8071 * doc/autoconf.texi (Special Shell Variables): Clarify
8072 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8074 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8076 * doc/autoconf.texi: Use @acronym for DJGPP.
8077 Fix some @code's that should have been @env's, and vice versa.
8078 Sort environment variable names.
8079 Mention that shells no longer inherit IFS.
8080 Don't recommend PATH_SEPARATOR=';' so strongly.
8081 Mention that $RANDOM might expand to the empty string.
8082 "symlink" and "soft link" -> "symbolic link".
8083 Improve mktemp description (reported by Bruno Haible).
8085 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8087 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8088 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8089 Likewise.
8090 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8091 Likewise.
8093 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8095 * NEWS: Mention AT_COPYRIGHT.
8097 * tests/local.at (AT_CMP): Use diff directly on input files rather
8098 than copying them.
8100 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8101 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8103 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8104 and Paul Eggert <eggert@cs.ucla.edu>
8106 * tests/autotest.at (Empty test suite): New test.

8108 (Substitute a 2000-byte string, Define to a 2000-byte string)
8109 (Substitute a newline, Define a newline): New tests.
8111 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8113 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8114 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8115 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8116 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8117 (Standard regular expressions): New test.
8118 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8119 excess test name quoting.
8120 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8121 CPPFLAGS to `configure' instead of setting it in `configure'.
8123 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8124 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8125 on some platforms.
8127 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8128 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
8130 * tests/local.at (AT_CMP): New macro.
8131 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

8135 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
8136 * tests/c.at (Extensions): Do not exit early.

8156 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8158 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8159 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8161 Try not to generated lines of unlimited length, as POSIX places a
8162 2047-byte limit on line length of portable text files.
8163 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8164 Use newline as a separator, not space.

8166 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
8167 space.

8171 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
8172 as_func_*. Add test to check whether positional parameters
8173 are restored after function return.
8175 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
8177 * doc/autoconf.texi (Special Shell Variables): Mention _,
8178 BIN_SH, DUALCASE. Say that variables other than "status" are safe
8179 if they contain a lower-case letter. The DUALCASE problem was
8180 reported by Ralf Wildenhues.
8182 * bin/autoconf.as: Don't exit with status 0 after write failure
8183 with --help or --version.
8184 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

8189 * doc/autoconf.texi (Limitations of Usual Tools):
8190 Unicos 9 sed limitations.
8191 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
8192 to get the option-enhanced interface on older Crays. Try ftn for
8193 Fortran 95 (newer Crays).
8195 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
8197 * man/Makefile.am (.x.1): Go back to the simple solution, but take
8198 care to echo the commands, so the user knows what's going on.
8199 Modified from a suggestion by Stepan Kasal.
8201 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

8208 * doc/install.texi (Defining Variables): Likewise.
8209 Based on a proposed patch by Ralf Wildenhues.
8211 * man/Makefile.am (.x.1): Make sure the required generated files
8212 are up to date. Problem and original solution proposed by Stepan Kasal.
8213 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
8214 implicit-man-prerequisites): New rules, used by the above.

8220 2005-01-29 Stepan Kasal <kasal@ucw.cz>
8222 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8223 Update the long comment explaining it.
8225 m4_require no longer writes an ``is required by'' line to the
8226 execution stack. It contains only one bit of non-redundant
8227 information: that the macro was required, not called. And even
8228 this bit is useless in most situations: have you ever met a macro
8229 which both calls and requires the same macro?
8231 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8232 (_m4_defun_pro_outer): ... only via this macro, for the outermost
8233 macro.
8234 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
8235 (m4_expansion_stack_pop): Remove the misplaced comment.
8236 (m4_require): Don't put the ``is required by'' line to the
8237 execution stack; slightly improve the out-of-a-defun error message.
8238 (_m4_divert_grow): New macro, counter for the temporary diversions.
8239 (_m4_require_call): Use it.
8240 * tests/m4sugar.at (m4_require): Expect output without the
8241 ``is required by'' messages.
8243 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8245 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
8246 rather than x for expr.
8248 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
8249 this is safe.
8250 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
8251 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

8258 Have autoheader honor --force.
8260 * doc/make-stds.texi, doc/standards.texi: Update from masters.
8261 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
8262 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
8263 from masters, so that FileUtils.pm's update_file provide --force
8264 support.
8265 * bin/autoheader.in: Pass $force to update_file so that

8651 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8652 "char c = '\200';" rather than "char c = 0x80;" as the

8734 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
8736 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
8737 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
8738 variants", "Unix", and some related minor wording fixups.
8740 (Shellology, Special Shell Variables): Document that the Zsh
8741 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
8742 to Alexandre Duret-Lutz for this info.
8744 2004-10-10 Alexandre Duret-Lutz <adl@gnu.org>

8753 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
8755 * doc/autoconf.texi (auindex): New macro.
8756 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
8757 Problem reported by Stepan Kasal.
8759 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
8761 Fix problems reported by Andreas Buening in:
8762 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
8763 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
8764 in test makefile.
8765 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
8766 readable; it's not true in OS/2-emx.
8768 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
8770 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
8771 "/usr/include", clear ac_x_includes instead of leaving it as "no"
8772 (trivial change). Problem and patch reported by Andrew Church in:
8773 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
8775 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
8777 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
8778 three args in examples. Problem reported by Frederik Fouvry in:
8779 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
8780 Also, fix some minor spacing and punctuation bugs.
8782 2004-09-02 Akim Demaille <akim@epita.fr>
8784 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
8785 "case" to restore ordering.
8786 Reported by Stepan Kasal.
8788 2004-08-26 Akim Demaille <akim@epita.fr>
8790 * doc/autoconf.texi: Minor typos and stylos.

8802 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
8803 texinfo.tex for now (done by hand now).
8804 * Makefile.maint (wget_files, cvs_files):
8805 Remove ansi2knr.c; nobody uses it.
8806 (ansi2knr.c-url_prefix): Remove.
8807 (cvs-update): Fix test for failure. I don't know why it ever
8808 worked...
8810 * doc/autoconf.texi: Update URLs, some of which went stale.
8811 Use @uref rather than @href.
8813 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
8814 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
8816 * config/config.guess, config/config.sub, config/elisp-comp,
8817 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
8818 doc/fdl.texi, doc/standards.texi: Sync with master copy.
8820 * NEWS, TODO, configure.ac, bin/autoscan.in,
8821 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
8822 doc/install.texi, lib/Autom4te/Configure_ac.pm,

8826 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
8827 tests/tools.at, tests/torture.at:
8828 Use "file name" rather than "filename" or "path",
8829 to be consistent with the terminology of the GNU coding standards.
8831 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
8833 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
8834 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
8835 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
8836 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
8838 More fixes to support spaces in the name of the build directory.
8839 This isn't a complete fix but it's an improvement.
8841 * bin/autoconf.as (autom4te_options): New var.
8842 Use it instead of appending to AUTOM4TE, so that we can allow
8843 spaces in the build directory's absolute name.
8844 * bin/autoheader.in ($autoconf): Allow spaces in file names.
8845 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
8846 AT_CHECK_NOESCAPE): Likewise.
8847 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
8848 main program): Likewise.
8850 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
8852 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
8853 From Ralf Corsepius in:
8854 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
8856 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
8858 * doc/autoconf.texi (Function Portability): Document isinf and
8859 and isnan. From a suggestion by Kevin Ryde.
8861 * lib/Autom4te/General.pm (END): Return correct exit status even
8862 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
8864 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
8866 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
8867 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
8868 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
8870 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
8872 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
8873 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
8874 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
8875 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
8876 * lib/autom4te.in (Automake-preselections): Preselect
8877 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8879 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8881 * lib/autom4te.in (Automake-preselections): Preselect
8882 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
8883 trace them.
8885 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
8887 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
8888 Tru64.
8889 * doc/autoconf.texi (Shellology): Mention BIN_SH.
8890 Document problem with "`""`" in pdksh POSIX mode.
8892 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
8894 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
8895 with pdksh, too. Problem reported by Patrick Welche via
8896 Gary V. Vaughan.
8897 * doc/autoconf.texi (Shellology): Note that set -o posix is
8898 useful for pkdsh, too.
8900 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
8902 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8903 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8904 Don't fail if ENV or BASH_ENV is readonly.
8905 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
8906 etc. are read only. Problem reported by Ludovic Courtes.
8908 2004-06-23 Noah Misch <noah@cs.caltech.edu>
8910 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
8911 zsh, disable GLOB_SUBST to avoid backslash handling problems.
8912 (trivial change)
8914 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
8916 * doc/autoconf.texi (File System Conventions): Warn about
8917 names like "aux". Problem reported by Eric Blake.
8919 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
8920 by zero instead of array size, so that we can use any arithmetic
8921 constant expression (instead of requiring an integer constant
8922 expression). This allows us to test expressions like DBL_MAX <
8923 LDBL_MAX, which didn't conform to the C standard using the old
8924 method.
8925 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
8926 now that we can do floating-point tests at compile time.
8928 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8930 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8931 and LDBL_EPSILON, as the resulting expression isn't an
8932 integer constant expression and violates the C standard.
8933 Problem reported by Nelson H. F. Beebe. Also, check
8934 for "L" suffix, and check that long double doesn't have
8935 worse range or precision than double, that mixed-mode
8936 arithmetic doesn't generate a diagnostic, that double
8937 constants fit in long double.
8939 2004-06-03 Kevin Ryde <user42@zip.com.au>
8941 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
8942 malloc(0) and realloc(NULL,size).
8944 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
8945 Bob Proulx.
8947 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
8949 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
8950 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
8951 by Jim Meyering.
8953 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8955 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
8956 can be rewritten using if-then-else. Suggested by Bruno Haible.
8958 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
8960 * doc/autoconf.texi (testsuite Scripts): Fix typo.
8961 Problem reported by Stepan Kasal.
8963 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8965 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
8966 change). Patch reported by Ralf Wildenhues in
8967 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
8969 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8970 function F exists if the compiler and linker let you compile an
8971 expression like (F != 0). Recent versions of GCC optimize away
8972 the reference to F in that case, since every function address must
8973 be nonzero, so the link succeeds even if F does not exist.
8974 Problem reported by Manu in
8975 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
8977 * doc/autoconf.texi (Systemology): Standardize on the spelling of
8978 "Unix". Many uses changed.
8979 (Limitations of Builtins): Explain better why the ! command isn't
8980 portable.
8982 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
8984 * lib/autom4te.in (Automake-preselections): Preselect
8985 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
8987 2004-05-19 Kevin Ryde <user42@zip.com.au>
8989 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
8990 referencing AC_FUNC_STRERROR_R.
8992 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
8993 note pessimistic assumption when cross compiling.
8995 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
8997 * doc/autoconf.texi (Limitations of Make): Note that BSD make
8998 (until 2004) invoked subcommands with sh -e, contra POSIX.
8999 Reported by Kevin Ryde.
9001 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9003 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9004 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9005 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9006 `test -f " /usr/bin/grep"', which _always_ failed.
9007 (AC_PROG_SED): Ditto bogus PATH fix.
9008 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9009 requires that grep correctly supports _multiple_ `-e' options, rather
9010 than stating only that grep should accept `-e'.
9012 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9014 Port to C99, which requires that 'exit' be declared.
9016 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9017 to ensure that stdlib.h is included.
9018 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9019 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9020 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9021 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9022 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9023 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9024 when using 'exit' in a test; C99 requires that 'exit' be declared.
9026 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9028 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9029 now prefers 'grep' implementations that accept -e.
9030 (Limitations of Usual Tools): Describe problems of traditional
9031 egrep and fgrep with long input lines, and of traditional grep
9032 with -e.
9033 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9034 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9035 All callers changed. Append /usr/xpg4/bin to the PATH, for
9036 Solaris.
9037 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9038 the user with complaints about multiple -e options.
9039 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9040 Define it with AC_PROG_GREP.
9041 * configure.ac (AC_PROG_GREP): Add.
9042 * lib/freeze.mk (GREP): New macro.
9044 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9046 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9047 a possible candidate only after all others fail, rather than
9048 consulting it first. This improves backward compatibility by
9049 better reflecting the way shell selection occurred in previous
9050 versions of Autoconf, and should help to avoid triggering latent
9051 problems in other packages, such as the one in Automake where zsh
9052 is not handled robustly:
9053 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9054 Although it is not Autoconf's responsibility to work around
9055 problems in Automake, it nevertheless makes sense to avoid
9056 introducing unnecessary incompatibilites.
9058 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9059 Gary V. Vaughan <gary@gnu.org>
9061 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9062 how deeply nested we are when a suitable tool is found, set the
9063 ac_path_TOOL_found flag.
9064 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9065 nested we are in this macro. Break out of all 3 nested loops if
9066 ac_path_TOOL_found is set.
9068 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9070 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9071 of the _AS_PATH_WALK loop too if GNU flavor is found.
9073 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9075 * doc/autoconf.texi (Limitations of Make): Update documentation
9076 for `$<'. New entry `Long lines', based on a report from Simon
9077 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9078 paragraph about DJGPP, based on a mail from Richard Dawe.
9080 2004-04-20 Paul Eggert <eggert@twinsun.com>
9082 * tests/c.at (C keywords): Don't assume that GCC supports
9083 "restrict" and "inline", as sufficiently-old GCC versions do not
9084 (also, GCC configured to be in pedantic C89 mode does not).
9085 Problem reported by Sumit Pandya in:
9086 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9088 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9089 consider -g to work if it generates warnings when plain compiles
9090 don't. Problem reported by Braden McDaniel in:
9091 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9093 * doc/autoconf.texi (Slashes): New section, to document a problem
9094 reported by Jim Meyering in:
9095 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9097 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9098 linker output files before linking, to work around IRIX 6 linker bug.
9099 Problem reported by Rainer Orth in:
9100 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9102 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9104 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9105 best tool so far counter rely on the tool path variable name to
9106 avoid checks for one tool being affected by the results of running
9107 the length check on a previous tool.
9109 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9110 match expression argument, as different greps have different
9111 regular expression flavours.
9112 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9113 literals.
9114 (AC_PROG_EGREP): Pass 'EGREP$'.
9115 (AC_PROG_GREP): Pass 'GREP$'.
9117 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9119 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9120 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9122 2004-03-29 Paul Eggert <eggert@twinsun.com>
9124 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9125 Types, Specific Compiler Characteristics, System Services,
9126 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9127 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9128 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9129 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9130 Likewise.
9131 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
9132 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
9133 AC_TYPE_OFF_T): Likewise.
9134 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
9135 Likewise.
9137 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
9138 pacify libtool 1.5.2. Fix quoting problems in sed command.
9140 2004-03-28 Paul Eggert <eggert@twinsun.com>
9142 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9143 now defines HAVE_DECL_TZNAME if it is declared, when
9144 HAVE_STRUCT_TM_TM_ZONE is not defined.
9145 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9146 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9147 for HAVE_TZNAME.
9149 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
9151 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
9152 superfluous backslashing of quotes (") in sed expressions;
9153 thanks to Paul Eggert.
9155 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
9157 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9158 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9159 H. F. Beebe for the bug report.
9161 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9163 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9164 quoted -cmdline argument in Portland Group compiler (bug
9165 reported by Jeffrey J. Barteet).
9167 2004-03-25 Kevin Ryde <user42@zip.com.au>
9169 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
9170 (Run Time): ... here, where it's now mentioned.
9172 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
9174 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
9175 inherits from language Autoconf-without-aclocal-m4.
9176 (Customizing autom4te): Adjust example; the cache must now be
9177 disabled for language Autoconf-without-aclocal-m4.

9190 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
9191 AC_CHECK_TOOLS.
9192 (Specifying Names): Document the reason for these future
9193 behavioral changes.
9194 * tests/mktests.sh: Do not generate tests for the
9195 new macros.
9196 * NEWS: Document these changes.
9198 * doc/autoconf.texi: Avoid macros with unbraced arguments,
9199 they make TeX hang up.
9201 2004-03-15 Paul Eggert <eggert@bogus.example.com>
9203 * NEWS: New macro AC_CHECK_ALIGNOF.
9204 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
9205 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
9206 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
9207 vowel.
9208 (AC_CHECK_ALIGNOF): New macro.
9209 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
9210 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
9211 those for sizeof.
9213 2004-03-03 Paul Eggert <eggert@twinsun.com>
9215 * bin/Makefile.am (edit): Don't use $< in a context where
9216 POSIX doesn't require support for it. Use $@.in instead.
9217 Problem reported by Anthony N. Frasso in
9218 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
9219 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
9221 2004-02-23 Gary V. Vaughan <gary@gnu.org>
9223 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
9224 from the next generation of Libtool.
9225 * lib/autom4te.in (Autoreconf-preselections): Ditto.
9227 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9229 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
9230 is not always thread-safe. Report from Nathanael Nerode.
9232 2004-02-18 Paul Eggert <eggert@twinsun.com>
9234 Fix a dependencies problem, stemming from a Autoconf 2.59 build
9235 problem on QNX reported by Stephen Rasku in
9236 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
9238 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
9239 $(m4sh_m4f_dependencies); this removes a FIXME.
9240 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
9241 (MAINTAINERCLEANFILES): Split into pieces,
9242 one per related section. Add $(srcdir)/wrapper.in.
9244 2004-02-09 Paul Eggert <eggert@twinsun.com>
9246 * doc/autoconf.texi (Setting Output Variables): Emphasize that
9247 AC_SUBST provides no portable way to escape literal newlines.
9249 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9250 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9251 Darwin uses -lcrt2.o and there's little point to cataloging all
9252 the system variants. Partial fix reported by Andreas Waechter in:
9253 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
9254 for bug reported by Nelson H. F. Beebe in:

9259 * doc/autoconf.texi (AU_DEFUN): Fix English,
9260 suggested by Paul Eggert.
9261 * lib/autoconf/autoupdate.m4: Correct reference to
9262 acobsolete.m4, suggested by Alexandre Duret-Lutz.
9264 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
9266 * bin/autoupdate.in: Define __file__ so that warnings
9267 refer to the correct file.
9268 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
9269 the behavior of the third argument.
9270 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
9271 correctly the behavior of the third argument. Document
9272 what the three macros that AU_DEFUN defines do. Fix
9273 warning message when the third argument includes $0
9274 (reported by Alexandre Duret-Lutz).
9276 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9277 Eric Sunshine <sunshine@sunshineco.com>
9278 Paul Eggert <eggert@twinsun.com>
9280 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
9281 (AS_INIT): Output shell initialization there. Removed optional
9282 parameter. Expand _AS_SHELL_FN_SPY.
9283 (AS_INIT_WITH_SHELL_FN): Removed.
9284 (_AS_SHELL_FN_SPY): New macro.
9285 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
9286 macros.
9287 (AS_SHELL_SANITIZE): Remove loop to find better shell
9288 and documentation for the parameter.
9289 (_AS_DETECT_BETTER_SHELL): Move it here.
9290 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
9291 (_AS_RUN): Move it here, support testing with eval.
9292 (AS_REQUIRE_SHELL_FN): Require shell functions when
9293 it is used.
9294 (_AS_LINENO_WORKS): Put around braces, we do not
9295 trigger the bash bug anymore.
9296 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
9297 use AS_INIT_WITH_SHELL_FN.
9298 * bin/autoconf.in, tests/wrapper.in: Regenerated.
9300 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9302 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
9303 * doc/autoconf.texi: Don't say that the third parameter
9304 is broken.
9305 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
9306 (AU_DEFUN): Honor the third parameter, create autoupdate
9307 macros with AU_DEFINE.
9308 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
9309 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
9310 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
9311 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
9312 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

9317 * lib/autoconf/status.m4: Remove FIXME.
9318 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
9319 that the macro is not present anymore in the updated
9320 configure.ac.
9321 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
9322 of autoupdate.
9324 2004-01-28 Paul Eggert <eggert@twinsun.com>
9326 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
9327 copyright years.
9328 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9329 2003 (except 1997) to the list of copyright years. This undoes
9330 the 2003-05-22 change, which removed the older years from the list.
9331 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
9333 2004-01-27 Gary V. Vaughan <gary@gnu.org>
9334 Albert Chin-A-Young <china@thewrittenword.com>

9337 grep or ggrep program in PATH that accepts as long lines as
9338 possible.
9339 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
9340 AC_PROG_GREP.

9342 egrep and fgrep respectively if $GREP -E/-F don't work.
9343 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
9344 _AC_PROG_GREP, and AC_PROG_SED.
9345 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
9346 longest input length accepted by a command.
9347 (AC_PROG_SED): Use it.
9348 * doc/autoconf.texi (Particular Programs): Document the changes.
9349 * NEWS: Updated.
9351 2004-01-27 Paul Eggert <eggert@twinsun.com>
9353 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
9354 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
9355 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
9356 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
9358 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
9359 bin/autoconf.in, config/Makefile.in, config/config.guess,
9360 config/config.sub, config/install-sh, config/mdate-sh,

9371 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
9372 tests/actypes.at: Regenerate and/or sync with original
9373 sources.
9375 2004-01-26 Paul Eggert <eggert@twinsun.com>
9377 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9378 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9379 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9380 not <inttypes.h>. Problem reported by Tim Mooney in
9381 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9382 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9383 Likewise.
9385 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9386 otherwise "make check" fails because it forbids cmp (I guess
9387 because cmp treats files as binary on DOS-like systems).
9389 * tests/mktests.sh: Update copyright date to 2004, since some tests
9390 have changed in 2004.
9392 2004-01-23 Gary V. Vaughan <gary@gnu.org>
9394 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
9395 non-truncating sed or gsed program in PATH.
9396 * tests/acprograms.at: Add it.
9397 * doc/autoconf.texi (Particular Programs): Document it.
9398 * NEWS: Updated.
9400 2004-01-15 Paul Eggert <eggert@twinsun.com>
9402 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9403 -std1 disables some useful extensions on Tru64. Problem reported
9404 by N. Lichtmaier in
9405 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
9407 2004-01-14 Paul Eggert <eggert@twinsun.com>
9409 * doc/autoconf.texi (Programming in M4sh): Document that
9410 AS_MKDIR_P succeeds if the destination is a symbolic link
9411 to an existing directory.
9412 (Limitations of Usual Tools): Note that mkdir -p might not
9413 succeed on symlinks to directories.
9415 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9417 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
9418 * bin/autoheader.in: Grammar fix in message.
9419 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
9420 Test for dir before calling mkdir -p. (trivial changes)
9422 2004-01-13 Eric Blake <ebb9@byu.net>
9424 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
9425 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
9427 2004-01-10 Jim Meyering <jim@meyering.net>
9429 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
9431 2004-01-09 Paul Eggert <eggert@twinsun.com>
9433 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9434 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9435 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9436 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9437 AC_COMPILE_IFELSE, since we now assume our caller invokes
9438 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9439 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9440 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9441 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9443 2004-01-07 Paul Eggert <eggert@twinsun.com>
9445 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9446 `"'...'"`, as it's confusing (and I suspect it may not work on
9447 some platforms). The code was incorrect anyway, as it assumed
9448 that \$ evaluated to itself in that context. Reported by
9449 Alexandre Duret-Lutz.
9451 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9453 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
9454 and _LT_AC_TAGCONFIG.
9456 2004-01-06 Paul Eggert <eggert@twinsun.com>
9458 * doc/autoconf.texi (One Macro Call): Fix an incorrect
9459 example, and add more examples. Reported by Eric Sunshine.
9461 2004-01-05 Paul Eggert <eggert@twinsun.com>
9463 * doc/autoconf.texi (Limitations of Usual Tools):
9464 Remove warning against "rm -fr" introduced yesterday; it
9465 was a false alarm.
9467 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
9468 autoscan, autoupdate, ifnames): Don't use chmod -w.
9469 * lib/Makefile.am (autom4te.cfg): Likewise.
9470 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
9471 "chmod -w".
9473 2004-01-04 Paul Eggert <eggert@twinsun.com>
9474 Paolo Bonzini <bonzini@gnu.org>
9476 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
9477 by doing lineno substitution only on lines containing "$LINENO".
9479 2004-01-04 Paul Eggert <eggert@twinsun.com>
9481 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
9482 Use "rm -f" to remove conftest.sed, not plain "rm".
9483 Bug reported by David Relson in
9484 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9486 * Makefile.am (autom4te-update):
9487 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
9488 * Makefile.maint (my-distcheck, do-po-update): Likewise.
9489 * doc/autoconf.texi (Guidelines): Likewise.
9490 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

9494 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
9495 * tests/Makefile.am (clean-local): Likewise.
9496 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
9497 srcdir): Likewise.
9498 * doc/autoconf.texi (Limitations of Usual Tools):
9499 Warn against "rm -fr".
9501 2004-01-03 Paul Eggert <eggert@twinsun.com>
9503 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9504 -c -o might not work. From a suggestion by Kevin Ryde.
9505 (C Compiler, Generating Sources, Limitations
9506 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9507 Don't put '-o' after non-options, as POSIX doesn't allow this.
9508 Mention that cc's name might be gcc or c89 or whatever.
9510 2004-01-04 Kevin Ryde <user42@zip.com.au>
9512 * doc/autoconf.texi: Add various further index entries.
9514 2003-12-29 Paul Eggert <eggert@twinsun.com>
9516 * bin/autoreconf.in (autoreconf_current_directory):
9517 Fix typo: mkdir without umask arg.
9519 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9521 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9522 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
9523 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
9524 explanation clearer.
9526 2003-12-24 Andreas Schwab <schwab@suse.de>
9528 * doc/autoconf.texi (Default Includes): Fix misspelling of
9529 AC_INCLUDES_DEFAULT.
9531 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
9533 * configure.ac: Test if sh -n works.
9534 * configure: Regenerate.
9535 * tests/atlocal.in: Store the result here.
9536 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
9537 tools.at, looking in atlocal's ac_cv_sh_n_works instead
9538 of explicitly testing.
9539 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
9540 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
9541 * tests/tools.at (Syntax of the shell scripts): Simplify
9542 using AT_CHECK_SHELL_SYNTAX.
9543 (Syntax of the Perl scripts): Remove definition of
9544 AT_CHECK_PERL_SYNTAX.
9546 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
9548 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
9549 stderr to /dev/null.
9550 * bin/autoconf.in: Regenerate.
9551 * bin/wrapper.in: Regenerate.
9553 2003-11-26 Paolo Bonzini <bonzini@gnu.org>
9555 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
9556 Extracted from AS_SHELL_SANITIZE.
9557 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
9558 macros.
9559 (AS_SHELL_SANITIZE): Move reinvocation code from
9560 _AS_LINENO_WORKS, use it to find out if shell
9561 functions work.
9562 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
9563 does not work.
9564 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
9565 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
9566 was called.

9576 (&sizes): New.
9577 Use them.

9579 them on the fly.
9581 2003-11-24 Akim Demaille <akim@epita.fr>
9583 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
9584 override some files.

9611 parameter of AU_DEFUN.
9612 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.
9613 (AU_DEFUN): Remove the third parameter, it was not used.
9614 Use AC_DEFUN directly, not AU_DEFINE.
9615 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
9616 the expanded body, consistently with other macros such as AC_USG.
9618 2003-11-17 Paul Eggert <eggert@twinsun.com>
9620 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes

9787 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
9788 cross test.
9790 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
9792 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
9793 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

9804 Issue a more-informative diagnostic.
9805 Problems reported by Eric Sunshine.
9807 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
9809 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
9810 -mGLOB_options_string stuff for Intel ifc, which can cause
9811 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

9820 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
9821 that future autopoint/aclocal/automake/autoreconf will be able

9828 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
9829 -lcrtbegin.o to list of ignored flags and fix underquoting of
9830 -lcrt[01].o.
9832 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
9834 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
9835 cache variable instead of $G77 to decide whether to include -O2,
9836 since $G77 is specific to Fortran 77.

9840 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
9841 free" flag. Re-order flags tested into rough order of popularity.
9843 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9845 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
9846 arguments so that it can be used with syntax identical to
9847 AC_PROG_F77, and so that we can more easily decide to
9848 remove/deprecate the DIALECT optional argument in the future if it
9849 proves troublesome.
9850 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
9851 non-freeform-supporting compilers. Document freeform flags.
9853 2003-10-03 Akim Demaille <akim@epita.fr>
9855 * configure.ac: Look for emacs, not macs.
9856 Reported by Eric Sunshine.
9858 2003-10-03 Akim Demaille <akim@epita.fr>
9860 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
9861 * bin/autoreconf.in (autoreconf_current_directory): Create the

9865 2003-10-03 Akim Demaille <akim@epita.fr>
9867 * configure.ac: Quotation and formatting changes.

9889 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
9890 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
9892 2003-09-30 Akim Demaille <akim@epita.fr>
9894 * config/announce-gen (&print_news_deltas): Extracted from...
9895 (&print_changelog_deltas): here.
9896 (&news_file): Rename as...
9897 (@news_file): this.
9899 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
9901 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
9902 have been created when invoking the compiler.
9903 * tests/fortran.at (GNU Fortran 77): Quote $G77.

9914 Problem reported by Lars J. Aas in
9915 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
9916 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
9917 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
9918 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
9920 2003-09-26 Akim Demaille <akim@epita.fr>
9922 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
9923 directory for AC_CONFIG_COMMANDS' first argument exists.
9924 This makes valid the invocation of _AC_SRCPATH that follows.
9925 Reported by Eric Sunshine.
9926 * doc/autoconf.texi (Configuration Commands): Adjust.
9928 2003-09-26 Akim Demaille <akim@epita.fr>
9930 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
9931 Reported by Ralf Corsepius.
9933 2003-09-26 Akim Demaille <akim@epita.fr>
9935 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
9936 arguments.
9937 Actually, use AU_ALIAS.
9938 From Bruno Haible.
9940 2003-09-26 Paul Eggert <eggert@twinsun.com>
9942 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
9943 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
9944 Problem reported by Eric Sunshine in:
9945 http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html
9947 2003-09-26 Akim Demaille <akim@epita.fr>
9949 The test suite are sometimes assigning timings incorrectly.
9950 Reported by Henk Krus.
9951 Diagnosed by Nicolas Joly.
9953 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
9954 AT_help_all.
9955 Instead of making AT_help a sequence of assignments to grow
9956 $at_help_all, just make AT_help_all be the growing contents of
9957 $at_help_all, and make a single assignment in...
9958 (AT_INIT): here.
9959 (at_times_skip): Flip the meaning and rename as...
9960 (at_times_p): this.
9961 (AT_INIT): When summarizing the test that ran, remove
9962 $at_times_file after use, and check it is present before trying to
9963 use it.
9965 2003-09-25 Akim Demaille <akim@epita.fr>
9967 Version 2.57d.
9969 * bin/Makefile.am (edit): Handle '@configure_input@'.
9970 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
9971 (ifnames): chmod -w.
9972 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
9973 executables, not bin/ executables! Otherwise all the magic needed
9974 to find non installed files is turned off. This caused a failure
9975 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
9976 as found in its environment (sent by tests/autoreconf): pointing
9977 to bin/autom4te that could not find its files.
9978 * tests/mktests.sh: Force the replacement of generated files, for
9979 the sake of "mv" program that are interactive when overwriting a
9980 -w file.
9981 * config/install-sh: Upgrade from CVS Automake.
9983 2003-09-23 Paul Eggert <eggert@twinsun.com>

9986 versus test -L issues.
9988 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
9989 Paul Eggert <eggert@twinsun.com>
9991 Trivial change to support GCC's configuration procedure.
9992 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
9993 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
9994 about inconsistency if the preprocessor is set to give errors for
9995 any warning.
9996 * doc/autoconf.texi (C Compiler Characteristics): Document this.
9998 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
10000 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm

10012 from masters.
10014 2003-09-12 Akim Demaille <akim@epita.fr>
10016 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
10017 not asm/types.h.
10019 2003-09-11 Akim Demaille <akim@epita.fr>
10021 * doc/autoconf.texi (Header Portability): linux/random.h.
10022 From Peter Hendrickson.
10024 2003-09-10 Akim Demaille <akim@epita.fr>
10026 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
10027 willing to edit the output files.
10029 2003-09-10 Akim Demaille <akim@epita.fr>
10031 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10032 and AC_FC_FREEFORM.
10033 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10034 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
10036 2003-09-09 Akim Demaille <akim@epita.fr>

10049 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
10050 Improve the accuracy of the wording about obsolescence.
10051 From a suggestion by Ian Lance Taylor in
10052 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
10054 2003-09-05 Paul Eggert <eggert@twinsun.com>
10056 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
10057 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
10059 2003-09-04 Akim Demaille <akim@epita.fr>
10061 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
10062 AC_FUNC_WAIT3.
10064 2003-09-04 Akim Demaille <akim@epita.fr>
10066 * bin/autom4te.in: Use &fatal where more appropriate than &error.
10067 (freeze): When exiting, use $exit_code.

10070 2003-09-04 Akim Demaille <akim@epita.fr>
10072 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10074 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10076 Add support for newer Fortran dialects. The F77 interface is
10077 unchanged, and continues to support Fortran 77. New FC macros
10078 correspond to all the old F77 macros, with output variables FC,
10079 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10080 available dialect, but older dialects can be specified. There are
10081 new macros AC_FC_SRCEXT to set the source extension, and
10082 AC_FC_FREEFORM to accept free-form source files.
10084 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
10085 New macros.
10086 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
10087 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
10088 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
10089 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

10098 AC_FC_SRCEXT, AC_FC_FREEFORM):
10099 New macros.
10100 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
10101 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
10102 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
10103 Rewrite in terms of the above.
10104 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
10105 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

10113 'touch -r' have.
10115 2003-08-27 Akim Demaille <akim@epita.fr>
10117 * tests/m4sugar.at (cross_warning): Make sure to enable the
10118 output, so that we can track spurious m4sugar output.
10119 * tests/local.at: Require 2.57.
10120 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10121 are defaulted by AT_CHECK anyway.
10122 Use AT_CHECK_AUTOM4TE.
10123 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
10124 missing dnl.
10126 2003-08-27 Akim Demaille <akim@epita.fr>
10128 * bin/autoheader.in: Issue the "Using auxiliary..." message only
10129 when -Wobsolete is set.
10130 Set it on by default.
10131 Suggested by Klee Dienes.
10133 2003-08-27 Akim Demaille <akim@epita.fr>

10142 after AC_OUTPUT.
10144 2003-08-25 Akim Demaille <akim@epita.fr>
10146 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
10147 CVS Bison.
10149 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
10151 * bin/autoreconf.in (parse_args): Do not pass --no-force to
10152 Automake versions prior to 1.8.
10154 2003-08-25 Akim Demaille <akim@epita.fr>
10156 * doc/autoconf.texi (Header Portability): netinet/if_ether.h.

10170 (local-check): New.
10172 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
10173 * configure.ac: Require Automake 1.7.6.
10175 2003-08-22 Akim Demaille <akim@epita.fr>
10177 Output stack traces in warnings.
10179 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
10180 Replace the former...
10181 (m4_warn): Pass the call stack to _m4_warn.
10182 * bin/autom4te.in: Adjust to output the call stack.
10183 * tests/m4sugar.at (m4@&t@_warn): Adjust.
10185 2003-08-22 Akim Demaille <akim@epita.fr>
10187 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
10188 * bin/autom4te.in: Adjust.
10190 2003-08-21 Akim Demaille <akim@epita.fr>
10192 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
10193 (&verbose): Remove.
10194 (&getopt): Adjust the note and verb channels, depending upon
10195 --verbose.
10196 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
10197 * bin/autoupdate.in: Adjust.
10198 Use &verb, not &verbose.
10200 2003-08-21 Akim Demaille <akim@epita.fr>
10202 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10203 &parse_WARNINGS.
10204 ($help): Use Autom4te::ChannelDefs::usage.
10205 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10206 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10208 2003-08-21 Akim Demaille <akim@epita.fr>
10210 First stab at preserving warnings between calls to autom4te,
10211 including when the cache is used.
10213 There are still several issues: (i) there are too many runs of m4
10214 (one for include, one for warnings, and some more), (ii) warnings
10215 spreading on several lines are not handled gracefully, (iii) the
10216 code meant to have the call stack display for errors does not work
10217 (its handling should move from m4 to autom4te).
10219 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10220 Use them.
10221 (@preselect): Add m4_warn.
10222 ($exit_status): Remove, use $exit_code.
10223 ($help): Use Autom4te::ChannelDefs::usage.
10224 (&handle_m4): No longer define the m4_warnings.
10225 At each run, extract and report the warnings.
10226 Always cache the result, including if the exit status is on
10227 failure, since if nothing changes, we should result in the same
10228 failure, hence we can use the cache.
10229 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10230 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10231 Remove.
10232 (m4_warn): Redefine as a do-nothing: it is its invocation that
10233 matters, as warnings are now reported via traces.
10234 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10235 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10236 the latter reveals calls to the former.
10238 Adjust the tests.
10240 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10242 2003-08-21 Akim Demaille <akim@epita.fr>
10244 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
10245 Use them.
10247 2003-08-21 Akim Demaille <akim@epita.fr>
10249 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
10250 forward order.
10251 * lib/Autom4te/ChannelDefs.pm: Doc typos.
10252 (&parse_warnings): Accept a list of warning requests.
10253 (&usage): Return a string, not a side effect.
10254 (cross): New warning category.
10256 2003-08-21 Akim Demaille <akim@epita.fr>
10258 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
10259 (&require_configure_ac): Accept an optional directory argument.
10260 ($configure_ac): Remove.
10261 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10262 (&catfile): Remove.
10263 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10264 * bin/autoscan.in: Adjust.
10266 2003-08-20 Akim Demaille <akim@epita.fr>
10268 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
10269 Reported by Alexandre Duret-Lutz.
10271 2003-08-20 Akim Demaille <akim@epita.fr>
10273 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10274 * bin/autom4te: Adjust.
10275 In particular, be Autoconf tools are really silent when properly
10276 working, bind the verbosity of the 'note' channel to $verbose.
10277 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10278 (&xsystem, &contents): Remove, since they are exported by...
10279 * lib/Autom4te/FileUtils.pm: this.
10280 More perldoc.
10281 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10282 * lib/Autom4te/FileUtils.pm: here.
10284 2003-08-20 Akim Demaille <akim@epita.fr>
10286 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
10287 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
10288 from CVS Automake.
10290 2003-08-20 Akim Demaille <akim@epita.fr>
10292 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
10293 (autom4te-update): New.
10294 * Makefile.cfg (update): Bind autom4te-update.
10296 2003-08-19 Derek Price <derek@ximbiot.com>
10298 * lib/autotest/general.m4: Comment various HELP_* diversions.
10299 (PARSE_ARGS_BEGIN): New section for option parsing related
10300 initialization.
10301 (AT_ARG_OPTION,AT_ARG_OPTION_ARG,_AT_ARG_OPTION): New macros to define
10302 package specific options and associated help.
10304 2003-08-19 Akim Demaille <akim@epita.fr>
10306 * config/announce-gen, Makefile.cfg: New.

10308 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
10310 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
10312 * lib/autom4te.in (Automake-preselections): Preselect
10313 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
10314 and m4_sinclude.
10316 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
10318 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
10319 (Autoconf-without-aclocal-m4): ... this new language.
10320 * doc/autoconf.texi (autom4te Invocation): Mention
10321 Autoconf-without-aclocal-m4.
10323 2003-08-18 Derek Price <derek@ximbiot.com>
10325 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
10326 RUN-IF-PASS optional arguments.
10328 2003-08-18 Derek Price <derek@ximbiot.com>

10335 STDOUT & STDERR arguments.
10337 2003-08-14 Derek Price <derek@ximbiot.com>
10339 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
10340 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
10341 shorter column three. Add DESCRIPTION to log file content.
10343 2003-08-13 Derek Price <derek@ximbiot.com>
10345 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
10346 output.
10348 2003-08-12 Derek Price <derek@ximbiot.com>
10350 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
10351 (AT_CHECK_NOESCAPE): Move core functionality to...
10352 (_AT_CHECK): ...this new macro.
10354 2003-08-07 Derek Price <derek@ximbiot.com>
10356 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
10357 (AT_CHECK_NOESCAPE): ...to this new macro.
10359 2003-07-31 Paul Eggert <eggert@twinsun.com>
10361 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
10362 in Bash 2.01. Problem reported by Brian Gough in
10363 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
10365 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
10367 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
10368 -lcrt1.o, for OS X. (trivial change)
10370 2003-07-07 Paul Eggert <eggert@twinsun.com>
10372 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
10373 inside '#ifndef __cplusplus'. Problem reported by
10374 Bob Friesenhahn.
10376 2003-07-06 Bill Clarke <llib@computer.org>
10378 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10379 'long', not 'int', for benefit of Sun's recent C++ compilers
10380 (trivial change). See:
10381 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
10382 (This really should be 'intptr_t', not 'long', but that would
10383 take more work.)
10385 2003-06-25 Akim Demaille <akim@epita.fr>
10387 * lib/Makefile.am (autom4te.cfg): Make it read only.
10388 Depend on Makefile since it contains substitutions.
10389 From Paolo Bonzini.
10390 * lib/autom4te.in (args): Add local.at? for Autotest args.
10391 This change was made on autom4te.cfg which is generated.
10392 Reported by Raja R. Harinath.
10394 2003-06-25 Akim Demaille <akim@epita.fr>
10396 * doc/autoconf.texi (Header Portability): sys/mount.h.
10397 From Gareth McCaughan.
10399 2003-06-23 Akim Demaille <akim@epita.fr>
10401 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10402 not all of them. This fixes 1. the fact that when testing
10403 Autoconf there are many many config.log, 2. the incorrect use of
10404 top_srcdir to find config.log.
10405 Don't mix the detailed output of failed test with the summary of
10406 failures. Rather, append detailed log afterwards.
10408 2003-06-23 Akim Demaille <akim@epita.fr>
10410 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
10411 always run: output config.log on $at_group_log.
10413 2003-06-23 Akim Demaille <akim@epita.fr>
10415 * tests/torture.at (#define header templates): Don't use quotes in
10416 C++ comments as it puzzles Emacs' sh font-lock-mode.
10418 2003-06-23 Akim Demaille <akim@epita.fr>
10420 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
10421 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
10422 * tests/atspecific.m4: Rename as...
10423 * tests/local.at: This.
10424 * tests/suite.at: Move the globals into...
10425 * tests/local.at: here.
10426 * tests/Makefile.am: Adjust.
10427 * doc/autoconf.texi (testsuite Scripts): Adjust.
10429 2003-06-21 Kevin Ryde <user42@zip.com.au>
10431 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
10432 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
10433 ensuring we add -std1 for full-ANSI.
10435 * doc/autoconf.texi (hdrindex): New macro.
10436 Add index entries for portability of various standard header files.
10438 2003-06-20 Akim Demaille <akim@epita.fr>
10440 * configure.ac: Bump to 2.57b.
10442 2003-06-20 Akim Demaille <akim@epita.fr>
10444 Version 2.57a.
10446 2003-06-20 Akim Demaille <akim@epita.fr>
10448 * bin/autom4te.in: Don't rely on $HOME being defined.
10449 Reported by Marc Espie as PR/233.
10451 2003-06-20 Akim Demaille <akim@epita.fr>
10453 * lib/autotest/general.m4: Use at_times_file only if used.
10454 From Nicolas Joly.
10456 2003-06-20 Akim Demaille <akim@epita.fr>
10458 * config/config.guess, config/config.sub, config/elisp-comp,
10459 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
10460 Update from masters.
10462 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
10464 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
10465 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
10466 (TEST_SCRIPT): New diversion.
10467 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
10468 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
10469 (AT_INIT): Support for expected failures.
10471 2003-06-02 Akim Demaille <akim@epita.fr>
10473 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
10474 changes.
10475 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
10476 Autoconf nor Automake.
10477 (&contents): New, from Automake.
10478 PODify.
10480 2003-05-28 Paul Eggert <eggert@twinsun.com>
10482 * NEWS, doc/autoconf.texi (Particular Functions),
10483 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
10484 is the inverse of localtime.
10486 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
10488 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10489 (handle_exec_errors): New function. Work around $! being
10490 altered by WEXITSTATUS.
10491 (xqx, xsystem): Use handle_exec_errors.
10493 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10495 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10496 Do not call `_exit()', simply modify `$?'.
10497 (xsystem): Reset $! before running system, and check it afterward.
10498 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10499 63 for version mismatches.
10501 2003-05-23 Akim Demaille <akim@epita.fr>
10503 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10504 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10505 the middle of a line).
10506 * lib/m4sugar/m4sugar.m4: Likewise.
10507 Remove useless spaces in comments.
10509 2003-05-23 Akim Demaille <akim@epita.fr>
10511 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10512 exit 63, so that we (or Automake's "missing") can tell the
10513 difference with a plain failure.
10514 * doc/autoconf.texi (Notices): Adjust.
10516 2003-05-23 Akim Demaille <akim@epita.fr>
10518 * Makefile.am, bin/Makefile.am, config/Makefile.am,
10519 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
10520 White spaces cleanup.
10522 2003-05-22 Jim Meyering <jim@meyering.net>
10523 Paul Eggert <eggert@twinsun.com>
10525 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10526 Remove `#include <stdlib.h>' from the list; we should never
10527 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10528 resulting namespace pollution would cause other tests to fail.
10529 Configure scripts run with some older versions of g++ and HP's
10530 aCC would fail due to such an #include. Problems reported by
10531 Matthew Mueller in <http://bugs.debian.org/120704> and by
10532 Keith Bostic in
10533 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10534 In the test, use the test declaration before including <stdlib.h>,
10535 as that's closer to how it'll be used.
10537 2003-05-23 Akim Demaille <akim@epita.fr>
10539 * doc/autoconf.texi (Header Portability): ucred.h.
10540 From Ian Redfern.
10542 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10544 Overhaul Autotest's logging: generate separate log files
10545 in testsuite.dir/NNN/testsuite.log, and append them to
10546 testsuite.log instead of re-running the test verbosely.
10548 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10549 file descriptor, write 0 to at_status_file instead of setting
10550 at_status=0, initialize some new variables (at_status_file,
10551 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10552 to rerun the tests, instead append the at_group_log to the
10553 at_suite_log when a test fails.
10554 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10555 with the AS_MESSAGE_LOG_FD redirected to stdout.
10556 (AT_CLEANUP): save the output status in $at_status_file
10557 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10558 its original place.
10559 (AT_CHECK): since tests are run with a redirected stdout,
10560 and used to be re-run in verbose mode, turn some $at_verbose
10561 into echo, and don't redirect the output of testing stdout
10562 and stderr.
10564 * lib/autotest/autoconf.texi (testsuite Scripts): Update

10689 by aclocal.m4 is changed it might require the importing of another
10690 m4 extension file, i.e., aclocal must be run.
10692 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10693 (&parse_args): Use --force with aclocal if required and supported.

10712 (AT_INIT): Allow --keywords to be specified more than once. When
10713 grepping $at_help_all for keywords, use the field and keyword
10714 seperators to ensure a complete keyword match. Alter at_prev handling

10793 * tests/torture.at (Configuring subdirectories): Require aclocal

10942 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10943 innocuous variant befor including <limits.h> or <assert.h>. This
10944 works around a bug reported by Albert Chin: HP-UX 11i
10945 (and earlier versions) have a <limits.h> that declares
10946 gettimeofday and many other functions.
10948 2002-12-03 Paul Eggert <eggert@twinsun.com>

10959 Martin Frydl in
10960 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
10962 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10963 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10964 defined, to support freestanding compilers. This should fix the
10965 bug reported by Momchil Velkov in
10966 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10968 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10969 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

11004 * Makefile.maint: Sync with Bison, i.e.:
11005 (po-check): Scan .l and .y files instead of the
11006 .c and the .h files that they generate. This fixes the bug
11007 reported by Tim Van Holder in:
11008 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11009 Look for N_ as well as for _. Try to avoid matching #define for

11030 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q

11039 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11041 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore

11068 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11069 Remove.
11070 We _have_ to stop using the old compatibility scheme that tried to
11071 avoid useless backslashes because Libtool 1.4.3 contains a
11072 AC_DEFINE([error_t], [int],
11073 [Define to a type to use for \`error_t' if it is not
11074 otherwise available.])
11075 We _have_ to quote the single quote and backslashes with \. The
11076 old compatibility scheme saw that ` was backslashed, and therefore
11077 did not quote the single quote. Hence before this patch, Autoconf
11078 was not compatible with Libtool.

11469 Reported by Alexandre Duret-Lutz.
11471 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

11492 if some file was changed instead of `print'.
11493 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

11511 * lib/autotest/general.m4 (AT_INIT): Include the failed test
11512 numbers in the Subject suggestion.
11514 2002-10-11 Akim Demaille <akim@epita.fr>
11516 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
11517 Suggest using AC_CHECK_DECLS instead.
11519 2002-10-11 Akim Demaille <akim@epita.fr>
11521 * tests/torture.at (AC_ARG_VAR): Have configure report the value
11522 of `precious'.
11524 2002-10-11 Akim Demaille <akim@epita.fr>
11526 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
11527 file name to enable parallel executions.
11528 From Sam Varshavchik.
11530 2002-10-08 Akim Demaille <akim@epita.fr>
11532 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11533 aclocal invocation, as Gettext macros might not be visible to
11534 aclocal.
11535 Instead of blindly running autopoint, scan configure.ac (not the
11536 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11537 Reported by Paul D. Smith.
11539 2002-10-08 Paul Eggert <eggert@twinsun.com>
11541 Work around problems found when POSIXLY_CORRECT=1 is set.
11542 None of this seems to have anything to do with POSIX, really,
11543 but it's how Perl getopt works.
11544 * bin/autom4te.in (parse_args): Configure GetOpt with
11545 "permute", too.
11546 * doc/autoconf.texi (Invoking autom4te):
11547 --warning -> --warnings.
11548 * lib/autom4te.in: --warning -> --warnings.
11550 2002-09-28 Akim Demaille <akim@epita.fr>
11552 * doc/autoconf.texi (autom4te.cache): New section.
11554 2002-09-28 Akim Demaille <akim@epita.fr>
11556 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
11557 (Automake-preselections): Update.
11558 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
11560 2002-09-28 Akim Demaille <akim@epita.fr>
11562 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
11563 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
11564 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11565 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
11567 2002-09-28 Akim Demaille <akim@epita.fr>
11569 * tests/torture.at (Configuring subdirectories): Be robust to
11570 users who use config.site to require for a cache: in this case,
11571 the two last configure runs, using two different sets of
11572 arguments, trigger a legitimate error.
11574 2002-09-28 Akim Demaille <akim@epita.fr>
11576 * tests/m4sh.at (Functions Support, Functions and return Support):
11577 New.
11579 2002-09-28 Akim Demaille <akim@epita.fr>
11581 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
11582 autoheader are Perl programs.
11583 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
11584 (autom4te): Specify that the sources are in the $srcdir.
11585 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11587 2002-09-28 Akim Demaille <akim@epita.fr>
11589 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
11590 (tm_zone): Move their rules to...
11591 * lib/autoconf/types.m4: here, using AN_ macros.
11592 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11593 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11594 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
11595 * lib/autoconf/programs.m4: here.
11596 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
11597 (ETAGS_FOR_AUTOCONF): New.
11598 Use it.
11600 2002-09-28 Akim Demaille <akim@epita.fr>
11602 * lib/autoconf/autoscan.m4: New file.
11603 * lib/autoconf/autoconf.m4: Include it.
11604 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
11605 that were listed in the original autoscan.list.
11606 * lib/autoconf/headers.m4: Similarly with headers.
11607 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11608 (.m4.m4f): Don't pass --prepend-include, since that's done by
11609 tests/autom4te itself.
11610 * lib/autoscan/Makefile.am: Include freeze.mk.
11611 (autoscan.list): New target --this file is no longer a source.
11612 (autoscan.pre): New file.
11614 2002-09-28 Akim Demaille <akim@epita.fr>
11616 * bin/autoscan.in (@kinds): Make them singular.
11617 Adjust all uses.
11618 (&init_tables): When --debug, report the list of rules to ease
11619 tracking changes in autoscan.list.
11620 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11622 2002-09-28 Akim Demaille <akim@epita.fr>
11624 * lib/autoscan/functions, lib/autoscan/headers,
11625 * lib/autoscan/identifiers, lib/autoscan/makevars,
11626 * lib/autoscan/programs: Merge into...
11627 * lib/autoscan/autoscan.list: this.
11628 * bin/autoscan.in (&init_tables): Adjust.
11630 2002-09-28 Akim Demaille <akim@epita.fr>
11632 * lib/autoscan/functions, lib/autoscan/headers,
11633 * lib/autoscan/identifiers, lib/autoscan/makevars,
11634 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11635 `functions' line is now prefixed with `function:'.
11636 * bin/autoscan.in (&init_tables): Adjust.
11638 2002-09-28 Akim Demaille <akim@epita.fr>
11640 From now on, autoscan files must always map a macro name to a
11641 word: there is no `default' macro for autoscan.
11643 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11644 all.
11645 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11646 explicit.
11648 2002-09-28 Akim Demaille <akim@epita.fr>
11650 * bin/autoscan.in (%c_keywords): Remove.
11651 (&used): Keep only track of the words we might be interested in.
11652 (&output_kind): It is no longer needed to look for non active
11653 checks.
11655 2002-09-27 Akim Demaille <akim@epita.fr>
11657 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
11658 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
11659 * lib/autoscan/functions: Adjust.
11660 * doc/autoconf.texi (Particular Functions): Adjust.
11662 2002-09-27 Akim Demaille <akim@epita.fr>
11664 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
11665 from /tmp.
11666 Thanks to Bill Moseley and Paul Eggert.
11667 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
11668 the tmpdir must be created.
11669 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
11670 dir be in the build tree, instead of $TMPDIR.
11672 2002-09-27 Akim Demaille <akim@epita.fr>
11674 * bin/autoscan.in: Improve the comments.
11675 (&parse_args): Drop obsolete undocumented options.
11676 (&output_kind): Output warnings.
11677 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
11678 (getwd): Trigger a warning.
11680 2002-09-26 Akim Demaille <akim@epita.fr>
11682 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
11683 Reported by Ralf Corsepius.
11684 * doc/autoconf.texi (autoreconf Invocation): Likewise.
11686 2002-09-26 Akim Demaille <akim@epita.fr>
11688 Single suffix rules and seperated dependencies are not portable.
11690 * doc/autoconf.texi (Installation Directory Variables): Update.
11691 (Limitations of Make): Some about `Single Suffix Rules and
11692 Separated Dependencies'.
11693 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11694 (ifnames, autoscan, autom4te): Un-factor into several rules.
11696 2002-09-25 Paul Eggert <eggert@twinsun.com>
11698 * BUGS (Interoperability bugs): New section. Mention libtool
11699 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
11701 2002-09-24 Paul Eggert <eggert@twinsun.com>
11703 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
11704 make handles suffix-rules differently from GNU make.
11706 * bin/Makefile.am (SUFFIXES, .in): Remove.
11707 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
11708 Move the body of the old .in rule here.
11710 2002-09-16 Akim Demaille <akim@epita.fr>
11712 i960 compilers create `b.out' files by default.
11713 Reported by Ralf Corsepius.
11715 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
11716 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
11718 2002-09-13 Paul Eggert <eggert@twinsun.com>
11720 * doc/autoconf.texi (Particular Headers): Remove obsolete
11721 reference to `struct timezone' in the description of
11722 AC_HEADER_TIME.
11724 2002-09-13 Akim Demaille <akim@epita.fr>
11726 Version 2.54.
11728 * config/config.sub, config/config.guess: Update.
11729 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
11730 * Makefile.am: Adjust.
11732 2002-09-13 Akim Demaille <akim@epita.fr>
11734 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
11735 reading config.log when the compiler is rejected.
11736 Suggested by Guido Draheim.
11738 2002-09-13 Akim Demaille <akim@epita.fr>
11740 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11741 (chdir_init) might hang when stat'ing mounted directories.
11742 Reported by Vance Shipley.
11744 2002-09-12 Akim Demaille <akim@epita.fr>
11746 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
11747 the lists.
11749 2002-09-12 Akim Demaille <akim@epita.fr>
11751 * doc/autoconf.texi (Defining Symbols): Present two different
11752 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
11753 difference between 1 argument calls, and 2-3 argument calls.
11755 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
11757 * doc/autoconf.texi: Review grammar and punctuation.
11759 2002-09-11 Paul Eggert <eggert@twinsun.com>
11761 * doc/autoconf.texi: Fix minor formatting, spelling, and
11762 grammatical typos.
11763 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
11764 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
11765 is obsolescent.
11767 2002-09-11 Akim Demaille <akim@epita.fr>
11769 * doc/autoconf.texi (Questions): Rename as...
11770 (FAQ): this.
11771 (Defining Directories): New.
11773 2002-09-09 Akim Demaille <akim@epita.fr>
11775 * doc/autoconf.texi (Making testsuite Scripts): Update.
11776 Suggested by Nishio Futoshi.
11778 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
11780 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
11781 plain `@' is wanted.
11783 2002-09-09 Akim Demaille <akim@epita.fr>
11785 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11786 `duplicates', since the algorithm was too naive and could keep
11787 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11788 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11789 Reported by Ralf Corsepius.
11790 * tests/torture.at (Configuring subdirectories): Exercise these
11791 cases.
11793 2002-09-09 Akim Demaille <akim@epita.fr>
11795 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
11796 looking for a replacement file.
11797 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11798 directory is relative.
11799 * doc/autoconf.texi (Generic Functions): Clarify the replacement
11800 directory definition.
11801 Reported by Andreas Schwab and Jim Meyering.
11803 2002-09-06 Akim Demaille <akim@epita.fr>
11805 * doc/autoconf.texi (Setting Output Variables): Clarify what
11806 precious variables are.
11807 Suggested by Pontus Skoeld.
11809 2002-09-05 Akim Demaille <akim@epita.fr>
11811 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11812 (ifnames, autoscan, autom4te): Since we don't only depend on
11813 configure.ac variables (such as VERSION etc.), but also on prefix
11814 and so forth, depend on Makefile, not configure.ac.
11815 Reported by Alexandre Duret-Lutz.
11816 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11818 2002-09-05 Kevin Ryde <user42@zip.com.au>
11820 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11821 doesn't seem to be confined to ia64, just say "some versions".
11823 2002-09-04 Akim Demaille <akim@epita.fr>
11825 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11826 Automake 1.6c.
11827 * Makefile.am (maintainer-clean-local): Remove.
11828 (MAINTAINERCLEANFILES): Remove COPYING.
11830 2002-09-03 Paul Eggert <eggert@twinsun.com>
11832 * doc/autoconf.texi (Configuration Commands): Remove obsolete
11833 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
11834 Brinkmann.
11836 2002-09-03 Akim Demaille <akim@epita.fr>
11838 * configure.ac: Bump to 2.53d.
11839 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11840 as of today, on Automake's team suggestion.
11842 2002-09-03 Akim Demaille <akim@epita.fr>
11844 Version 2.53c.
11846 2002-09-02 Akim Demaille <akim@epita.fr>
11848 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
11849 SITE_MACRO_DIR.
11850 * configure.ac: Disable SITE_MACRO_DIR.
11852 2002-09-02 Jim Meyering <meyering@lucent.com>
11854 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11855 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11856 Also, tweak grammar: s/make sure to/be sure to/.
11858 2002-09-02 Paul Eggert <eggert@twinsun.com>
11860 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11861 directory names are generally preferable to physical names.
11863 2002-09-02 Akim Demaille <akim@epita.fr>
11865 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11866 Reported by Raja R. Harinath.
11867 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11868 * bin/autoupdate.in: Use error instead of die.
11870 2002-09-01 Paul Eggert <eggert@twinsun.com>
11872 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11873 ordinary shell concatenation rather than echo+tr+sed command that
11874 runs afoul of a long-line-related sed bug in Solaris 8.
11876 * bin/autoheader.in (parse_args): --warning -> --warnings.
11878 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11879 stdout, as traditional "ls" does.
11880 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11881 _AC_COMPILER_EXEEXT_O): Likewise.
11882 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11884 * bin/autoconf.as: Add --prepend-include option. This patch was
11885 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11886 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11888 * bin/autoconf.in, configure: Regenerate.
11890 * doc/autoconf.texi (Special Shell Variables): Mention
11891 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11893 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11894 MAILPATH and set PS1, PS2, PS4 to default values, to work
11895 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11896 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11897 the Autoconf documentation specifies; fall back to "unset" only if
11898 this fails. Use a shell for-loop for this rather than an m4 loop,
11899 to shorten the output script.
11901 2002-08-30 Paul Eggert <eggert@twinsun.com>
11903 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11904 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11905 for the CDPATH problem. Document PWD.
11906 (Limitations of Builtins): Document the problem that "cd $foo" and
11907 "ls $foo" may refer to different directories in shells conforming
11908 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11909 example, since the old example is now out of date.
11911 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11912 FOO" and "ls FOO" talk about different directories; this catches
11913 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11914 spaghetti.
11916 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11917 of rolling our own unset.
11918 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
11919 in practice we needn't worry about CDPATH if unset doesn't work.
11921 * Makefile.in, aclocal.m4, bin/Makefile.in,
11922 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
11923 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
11924 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
11925 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
11926 tests/Makefile.in: Regenerate with Automake 1.6.3.
11928 * config/config.guess, config/config.sub, config/mkinstalldirs:
11929 Update.
11931 * configure: Regenerate with self.
11933 2002-08-30 Kevin Ryde <user42@zip.com.au>
11935 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
11936 default output.
11938 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
11940 * bin/autom4te.in (Request::load): Correctly test for "do" read
11941 failure.
11943 2002-08-29 Akim Demaille <akim@epita.fr>
11945 * lib/Autom4te/General.pm (&xqx): New.
11946 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11947 hand, which is not portable.
11948 (&error): New.
11949 * bin/autom4te.in: Use them.
11950 Use &error instead of die.
11951 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11952 Adjust.
11954 2002-08-17 Paul Eggert <eggert@twinsun.com>
11956 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
11957 default list of compilers to try, since it was long ago superseded
11958 by the ksh fc builtin. Suggested by Steven G. Johnson.
11960 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
11962 * doc/autoconf.texi (Invoking autom4te): End the option table,
11963 fixing a bug introduced by the previous patch.
11964 (Limitations of Make): Add a 'target lookup' subentry in the
11965 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
11967 2002-07-29 Mark D. Roth <roth@feep.net>
11969 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
11970 options and use $AUTOM4TE_PATH.
11971 * doc/autoconf.texi: Remove documentation of autom4te
11972 --include-envvar and --site-macro-subdir options and document
11973 use of $AUTOM4TE_PATH.
11974 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
11975 arguments from each language section.
11977 2002-07-29 Paul Eggert <eggert@twinsun.com>
11979 * doc/install.texi: Include copyright symbol in copyright notice.
11981 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
11982 Replace with:
11983 (AM_MAKEINFOFLAGS): New macro.
11984 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
11985 * Makefile.am (INSTALL): Use the new macros.

11988 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11990 * doc/autoconf.texi (Limitations of Make): Escaped newlines in

11996 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):

12001 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):

12135 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
12137 * tests/mktests.sh: Use grep instead of fgrep, as per
12138 "Limitations of Builtins".
12140 2002-06-15 Paul Eggert <eggert@twinsun.com>
12142 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
12143 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
12144 so that we consistently test the just-built programs.
12145 * tests/wrappl.as: Likewise.
12147 2002-06-12 Paul Eggert <eggert@twinsun.com>
12149 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

12163 * doc/autoconf.texi: Add more dir entries.
12165 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
12167 * bin/autom4te.in ($cache): Don't define using `$me', the name
12168 of the cache should not depend on the name under which autom4te
12169 was installed.
12171 2002-06-07 Akim Demaille <akim@epita.fr>

12187 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
12188 AC_FUNC_FNMATCH_GNU.
12190 2002-06-07 Akim Demaille <akim@epita.fr>

12197 * bin/autom4te.in (warn_forbidden): When rejecting a token,

12199 Suggested by Adam J. Richter.
12201 2002-06-07 Akim Demaille <akim@epita.fr>
12203 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
12204 ac_config_libobj_dir.
12205 (AC_CONFIG_LIBOBJ_DIR): New.
12206 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
12207 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
12208 Use ac_config_libobj_dir to find the replacement files.
12209 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
12210 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)

12213 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
12214 * tests/mktests.sh (ac_exclude_list): Don't check

12228 Update from masters.
12230 2002-05-29 Paul Eggert <eggert@twinsun.com>

12253 * NEWS, doc/autoconf.texi (Particular Types): Document it.
12254 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it

12262 2002-05-22 Paul Eggert <eggert@twinsun.com>
12264 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
12265 from the default list of compilers to try. Suggested by
12266 Kate Hedstrom.
12267 * NEWS: Document the above.
12268 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
12270 2002-05-17 Paul Eggert <eggert@twinsun.com>
12272 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12273 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12274 This improves on an earlier suggestion by H. Peter Anvin.
12276 2002-05-16 Paul Eggert <eggert@twinsun.com>
12278 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12279 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12280 Both macros now accept an optional source-dir arg.
12281 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12283 * NEWS: Document this.
12284 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12286 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12287 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12288 not for GNU extensions; this undoes part of the 2000-11-03 change,
12289 reverting to 2.13-compatible behavior.
12290 Add new optional argument DIR.
12291 (AC_FUNC_FNMATCH_GNU): New macro.
12293 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12295 2002-05-08 Paul Eggert <eggert@twinsun.com>
12297 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12298 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12299 and it causes a 'test' syntax error if it fails.
12300 Bug reported by Stephen Gildea.
12302 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12303 If prototypes are supported, use them to check this at compile-time,
12304 instead of trying to check it at run-time. If we must do a run-time
12305 check, assume that setvbuf is standard when cross-compiling, as
12306 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12307 Bug reported by Paul D. Smith.
12309 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12310 argument specifying location of getloadavg.c. This removes a
12311 FIXME. This idea was taken from Jim Meyering's implementation in
12312 textutils.
12313 * doc/autoconf.texi (Particular Functions): Document this.
12314 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12315 that's what the code does; this fixes a bug reported by
12316 Paul D. Smith.
12318 2002-05-03 Akim Demaille <akim@epita.fr>
12320 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12321 autopoint instead of gettextize.
12322 ($uses_alocal): Rename as...
12323 ($uses_aclocal): this.
12324 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12325 Suggested by Bruno Haible.
12327 2002-05-03 Akim Demaille <akim@epita.fr>
12329 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12331 2002-04-29 Paul Eggert <eggert@twinsun.com>
12333 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12334 files to be 1 second older; just set them to be the same time.
12335 Also, sleep 1 second after the first aclocal, to work around
12336 problems with sub-second time stamps on the input files.
12338 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12340 * doc/autoconf.texi: Mention "set -e -x" lossage
12341 under node "Limitations of Builtins".
12343 2002-04-29 Akim Demaille <akim@epita.fr>
12345 * doc/install.texi: Better wording for setting variables when
12346 running configure.
12347 From Christian Cornelssen.
12349 2002-04-29 Akim Demaille <akim@epita.fr>
12351 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12352 of lack of $LINENO support, then the test will compare the $LINENO
12353 in testsuite vs. the lineno in the test file. This is wrong, of
12354 course.
12355 Be sure to protect it.
12356 Reported by Patrick Welche.
12358 2002-04-25 Akim Demaille <akim@epita.fr>
12360 * doc/autoconf.texi (Obsolete Macros): Typo.
12361 Reported by Vladimir Volovich.
12363 2002-04-25 Akim Demaille <akim@epita.fr>
12365 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12366 than some of the input files, hence, on the second run of aclocal,
12367 if some of its input are younger, make them older.
12368 Suggested by Paul Eggert.
12370 2002-04-25 Akim Demaille <akim@epita.fr>
12372 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
12373 Thanks to Paul Eggert.
12375 2002-04-25 Akim Demaille <akim@epita.fr>
12377 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12378 and ac_subst_vars be sh variables containing the list of
12379 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12380 DEFAULT diversion.
12381 (_AC_INIT_PREPARE): Use them to log them.
12382 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12383 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12384 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12385 _AC_SUBST_FILES and _AC_SUBST_VARS.
12386 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12388 2002-04-24 Akim Demaille <akim@epita.fr>
12390 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12391 autoheader, so that automake does not complain about a missing
12392 config.h.in that was to be created.
12394 2002-04-23 Akim Demaille <akim@epita.fr>
12396 * bin/autoheader.in (parse_args): --warning takes an argument.

12445 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
12446 Minor spelling and grammar fixes.
12448 * doc/autoconf.texi: Follow the outline suggested in the GNU
12449 Sample Texts sections of the Texinfo 4.2 manual. Most
12450 importantly, this makes sure that the copyright notices appear in
12451 all output formats. You probably need Texinfo 4.2 to generate
12452 the manual now.
12454 Fix some bugs when using "$@" when there might be zero positional
12455 arguments in cases where this matters.
12457 * bin/autoconf.as: Rewrite so that the problem does not come up.
12458 * lib/autoconf/programs.m4 (AC_CHECK_PROG): Likewise.

12469 * doc/autoconf.texi (Shell Substitutions): Document the problem.
12471 * lib/autotest/general.m4 (AT_INIT):
12472 Use Zsh alias to work around problem.
12473 * tests/atgeneral.m4 (AT_INIT): Likewise.
12475 * tests/c.at: We can't have zero arguments, so remove workaround
12476 that is not portable to Zsh.
12478 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
12480 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

12490 workaround for ${1+"$@"}.
12491 * doc/autoconf.texi (Shell Substitutions): Explain it.
12492 From Oliver Kiddle and Peter Stephenson.
12494 Have M4sh perform minimal shell sanitizing.
12496 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12497 part into...
12498 (_AS_PREPARE): this new macro.
12499 (AS_PREPARE): New.
12500 (AS_INIT): Invoke AS_SHELL_SANITIZE.
12501 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
12503 Adjust Autoconf and Autotest.
12505 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12506 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12507 * lib/autotest/general.m4 (AT_INIT): Likewise.
12508 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
12509 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
12510 AS_SHELL_SANITIZE.
12512 Use this M4sh to generate Autoconf's shell scripts.
12514 * tests/wrapsh.as: New, precursor of wrapsh.in.
12515 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12516 on Autotest and M4sh.
12517 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12518 (wrapsh.in): New target.
12519 * bin/autoconf.as: New, precursor of autoconf.in.
12520 (autoconf.in): New target.
12522 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
12524 * doc/autoconf.texi (Limitations of Make): Mention the issue
12525 with indented comments in rules.
12527 2002-04-09 Andreas Schwab <schwab@suse.de>
12529 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
12530 ac_top_builddir when setting ac_abs_top_builddir.
12532 2002-04-06 Kevin Ryde <user42@zip.com.au>
12534 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
12535 (Portable Shell): Cross reference to Systemology.
12537 2002-04-05 Akim Demaille <akim@epita.fr>
12539 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
12540 directories when descending in a SUBDIRS.
12541 Reported by Ezra Peisach.
12543 2002-04-04 Andreas Schwab <schwab@suse.de>
12545 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
12546 contains no literal separators.
12548 2002-04-03 Akim Demaille <akim@epita.fr>
12550 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
12551 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
12552 Use dnl, not the KILL diversion.
12553 Extracted from...
12554 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12555 (AC_CONFIG_LINKS): here.
12556 Adjust.
12557 Don't use the KILL diversion, as it kills spurious output, which
12558 results in failures being hidden.
12559 Use m4_defn where appropriate.
12560 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12561 after the second argument.
12562 Use m4_defn.
12563 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12564 syntax, as it is provided by M4sugar.
12565 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
12567 2002-04-03 Andreas Schwab <schwab@suse.de>
12569 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
12570 expanded if $# <= 2.
12572 * bin/autoreconf.in (autoreconf): Run automake after rerunning
12573 aclocal.
12575 2002-04-03 Akim Demaille <akim@epita.fr>

12578 (_AC_COMPILER_EXEEXT_REJECT): New.
12579 Also recognize *.bb and *.bbg as compilation byproducts.
12580 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
12581 (_AC_COMPILER_OBJEXT): Use them.
12582 Fixes Debian #138666.
12584 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
12586 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12588 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12589 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12590 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
12591 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
12592 (AC_C_CONST): Same.
12593 (AC_C_INLINE): Same.
12594 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
12595 * doc/autoconf.texi, NEWS: Document.
12596 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
12597 AC_C_CROSS.

12604 2002-03-28 Kevin Ryde <user42@zip.com.au>
12606 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12607 to avoid versions of HP C which don't allow that.
12609 2002-03-27 Paul Eggert <eggert@twinsun.com>
12611 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12612 (AS_SHELL_SANITIZE): Invoke it.
12613 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
12615 2002-03-26 Akim Demaille <akim@epita.fr>
12617 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
12619 2002-03-26 Akim Demaille <akim@epita.fr>
12621 * doc/autoconf.texi (Introduction): The GNATS base moved.
12623 2002-03-25 Paul Eggert <eggert@twinsun.com>
12625 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12626 as POSIX requires, as it doesn't work with Zsh.
12627 * doc/autoconf.texi (Assignments): Document the problem.
12629 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12631 * doc/autoconf.texi (Limitations of Make): Mention more issue
12632 about VPATH, overriding of macros in sub-makes, and handling of
12633 SHELL.
12635 2002-03-21 Paul Eggert <eggert@twinsun.com>
12637 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12638 problem with here-document buffer boundaries.
12640 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12641 when reinvoking the shell, to work around problems with installers
12642 who put strange things like "cd" commands in their environments.
12644 2002-03-19 Akim Demaille <akim@epita.fr>
12646 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
12647 From Aaron Ucko.
12649 2002-03-19 Akim Demaille <akim@epita.fr>
12651 * bin/autoscan.in (scan_file): Specify the location in `&used'
12652 invocations.
12653 From Nicolas Joly.
12655 2002-03-19 Akim Demaille <akim@epita.fr>
12657 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
12658 From Nishio Futoshi.
12660 2002-03-19 Akim Demaille <akim@epita.fr>
12662 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
12664 2002-03-18 Paul Eggert <eggert@twinsun.com>
12666 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12667 (Limitations of Usual Tools): Add mkdir section.
12669 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12670 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12671 back on AS_DIRNAME to compute prefixes otherwise; this is
12672 roughly what mkinstalldirs does. That way, we need not have
12673 our own filename disassembler. The old disassembler did not
12674 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12676 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12677 Create at_test_all by a series of assignments,
12678 not by a single assignment of a long string. The latter causes ksh
12679 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12680 presumably because of a buffer overrun.
12682 2002-03-14 Paul Eggert <eggert@twinsun.com>
12684 * lib/autotest/general.m4 (at_times_skip):
12685 Renamed from at_times. Now a boolean.
12686 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12687 says 'times: not found'.
12689 2002-03-14 Akim Demaille <akim@epita.fr>
12691 * bin/autoreconf.in (&study_gettextize): New.
12692 (&autoreconf): Handle newest gettextize.
12693 Rerun aclocal if needed.
12694 Suggested by Andreas Schwab.
12696 2002-03-13 Akim Demaille <akim@epita.fr>
12698 * doc/autoconf.texi (Special Shell Variables): More about IFS.
12700 2002-03-13 Akim Demaille <akim@epita.fr>
12702 * doc/autoconf.texi (Header Portability): New.
12703 Add information about stdint.h and inttypes.h from Paul Eggert.
12705 2002-03-13 Akim Demaille <akim@epita.fr>
12707 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
12708 -p'.
12709 From Bob Proulx.
12711 2002-03-12 Akim Demaille <akim@epita.fr>
12713 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
12714 m4_require.
12716 2002-03-11 Andreas Schwab <schwab@suse.de>
12718 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
12719 does not do it if --with-lispdir is given.
12721 2002-03-08 Akim Demaille <akim@epita.fr>
12723 Version 2.53.
12725 2002-03-08 Akim Demaille <akim@epita.fr>
12727 * doc/autoconf.texi (Subdirectories): Clarify that the
12728 subdirectory should exist.
12730 2002-03-08 Akim Demaille <akim@epita.fr>
12732 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12734 2002-03-08 Akim Demaille <akim@epita.fr>
12736 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12737 aliases the actual variables, and modifications of the former
12738 affect the latter.
12740 2002-03-08 Akim Demaille <akim@epita.fr>
12742 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12743 because of C-c: have m4 output in tmp files, then mv them.
12745 2002-03-08 Akim Demaille <akim@epita.fr>
12747 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
12748 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
12749 * bin/ifnames.in: Copyright update.
12751 2002-03-08 Akim Demaille <akim@epita.fr>
12753 * doc/autoconf.texi (Invoking autom4te): New.
12755 2002-03-05 Akim Demaille <akim@epita.fr>
12757 * doc/autoconf.texi (Specifying Names): Clarification suggested by
12758 Kevin Ryde.
12760 2002-03-05 Akim Demaille <akim@epita.fr>
12762 Version 2.52i.
12764 2002-03-04 Akim Demaille <akim@epita.fr>
12766 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
12767 * lib/autoconf/general.m4 (AC_INIT): More informative error
12768 message for LIBOBJ.
12770 2002-03-04 Akim Demaille <akim@epita.fr>
12772 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
12773 parallel builds.
12775 2002-03-04 Akim Demaille <akim@epita.fr>
12777 * doc/autoconf.texi (Transforming Names): Equality between target
12778 and host is irrelevant.
12779 (Specifying Names, Canonicalizing): Remove all references to the
12780 backward compatibility hooks. Rather, collect them all into...
12781 (Hosts and Cross-Compilation): this new section.
12782 * doc/install.texi (System Type): Ditto.
12783 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12784 that `--host' implies cross-compilation.
12786 2002-03-04 Akim Demaille <akim@epita.fr>
12788 * doc/autoconf.texi (Evaluation Macros): New.
12789 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12790 useless.
12791 (_m4_foreach): Define the variant with immediate evaluation so
12792 that it contains exactly the items, not an expression which
12793 evaluation is the current item.
12794 (m4_re_string, m4_re_word): Don't over quote them.
12796 2002-03-04 Akim Demaille <akim@epita.fr>
12798 Instead of having stacking `shift's evaluated at the end, let
12799 `foreach' loops immediately evaluate them.
12801 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12802 $*. This is the n-th time I change my mind, but hopefully this is
12803 the last...
12804 (m4_lquote): New.
12805 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12806 efficient.
12807 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12808 it was only a hack for m4_text_wrap.
12809 (m4_car2): Remove, replaced by...
12810 (m4_cdr): New.
12811 (_m4_foreach): Adjust.
12812 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12813 m4_bpatsubst for clarification.

12853 Version 2.52h.
12855 2002-02-07 Akim Demaille <akim@epita.fr>
12857 Fix Autoconf PR/209.
12858 Also reported by Frank Denis.
12860 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
12862 2002-02-07 Akim Demaille <akim@epita.fr>
12864 Fix Autoconf PR/207:
12865 AC_PREFIX_PROGRAM fails with dashed program names
12867 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
12868 variable when looking for the prefix program.

12899 not unsigned long.
12900 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
12901 cross-compilers, too. This undoes some of the most recent change
12902 to this file.
12904 2002-02-05 Akim Demaille <akim@epita.fr>
12906 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

12926 2002-02-05 Akim Demaille <akim@epita.fr>
12928 * bin/autom4te.in (&parse_args): Implement `frozen files are
12929 optional are the sum of the previous files on the command line'.
12930 Also, pass `--reload-state=' on them, so...
12931 (handle_m4): don't.
12932 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
12933 (M4sh): Rely on M4sugar.
12934 (Autotest, M4sh, M4sugar): Use frozen files.
12936 2002-01-31 Akim Demaille <akim@epita.fr>
12938 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
12939 * doc/autoconf.texi (Initializing configure): Adjust.
12941 2002-01-30 Akim Demaille <akim@epita.fr>
12943 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
12944 alphanumeric to `-' instead of `_'.
12946 2002-01-30 Akim Demaille <akim@epita.fr>
12948 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
12949 for plain code, the other for cross-compilation code. The latter
12950 is now run with GCC only.
12951 * doc/autoconf.texi (Compilers and Preprocessors): New.
12953 2002-01-30 Akim Demaille <akim@epita.fr>
12955 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
12956 values.
12957 * doc/autoconf.texi (Initializing configure): Explain how to
12958 change AC_INIT default values.
12960 2002-01-29 Akim Demaille <akim@epita.fr>
12962 * tests/torture.at (Configuring subdirectories): Use configure.in,
12963 so that aclocal 1.4 works.
12964 Reported by Alexandre Duret-Lutz and Larry Schmitt.
12966 2002-01-28 Akim Demaille <akim@epita.fr>
12968 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
12969 needs an argument.
12971 2002-01-28 Akim Demaille <akim@epita.fr>
12973 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12974 AUTOTEST_PATH *after* it was set.
12975 Don't put `.' in the PATH: the user should be precise and `./' if
12976 needed. In addition, given that the test suite does some `cd', if
12977 `.' is in the path, the `tested programs' sections will report
12978 programs found in the test suite's directory, while during the
12979 tests (performed in their own directory), these programs are no
12980 longer visible. In other words, the results is confusing and
12981 useless.
12982 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
12984 2002-01-24 Akim Demaille <akim@epita.fr>
12986 Version 2.52g.
12988 2002-01-24 Akim Demaille <akim@epita.fr>
12990 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
12991 * doc/autoconf.texi: Finally add Akim as an author.
12993 2002-01-24 Akim Demaille <akim@epita.fr>
12995 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
12996 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
12997 Bourne. Use /bin/sh.
12998 From Andreas Buening.
13000 2002-01-24 Akim Demaille <akim@epita.fr>
13002 * config/config.guess, config/config.sub, config/texinfo.tex:
13003 Update from masters.
13005 2002-01-24 Akim Demaille <akim@epita.fr>

13009 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
13010 * config/missing.m4, config/sanity.m4, config/select.m4,
13011 * config/strip.m4: Remove, to ease sync'ing with any version of
13012 Automake.
13014 2002-01-24 Akim Demaille <akim@epita.fr>
13016 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13017 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13018 Reported by Geir Ove Myhr.
13020 2002-01-21 Akim Demaille <akim@epita.fr>
13022 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
13024 2002-01-21 Akim Demaille <akim@epita.fr>
13026 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13027 message on invalid options.
13028 * bin/autom4te.in (parse_args): Don't use
13029 Autoconf::General::getopt with non valid options.
13031 2002-01-17 Jim Meyering <meyering@lucent.com>
13033 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13034 $ac_cv_exeext so we don't use an old, invalid, cached value.
13036 2002-01-11 Akim Demaille <akim@epita.fr>
13038 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
13039 Meyering.

13041 limitation.

13045 2002-01-06 Akim Demaille <akim@epita.fr>
13047 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13048 package.m4, since is really depends upon configure.ac, not
13049 configure.
13050 * doc/autoconf.texi (testsuite Scripts): Adjust.
13051 * tests/Makefile.am (package.m4): New.
13052 EXTRA_DIST it since its a source.
13054 2002-01-06 Akim Demaille <akim@epita.fr>
13056 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13057 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13058 and PACKAGE_BUGREPORT from here...
13059 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13060 arguments.
13061 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13062 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13063 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13064 * tests/tools.at (autoheader): Adjust.
13065 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13067 2002-01-06 Akim Demaille <akim@epita.fr>

13071 2002-01-03 Akim Demaille <akim@epita.fr>
13073 * doc/autoconf.texi (Output): Improved wording regarding use of
13074 AC_OUTPUT.
13075 From Olly Betts.
13077 2001-12-18 Kevin Ryde <user42@zip.com.au>
13079 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13080 sometimes needing writable input.
13082 2001-12-17 Jim Meyering <meyering@lucent.com>
13084 * doc/autoconf.texi (New Macros): Tweak wording.
13086 2001-12-14 Akim Demaille <akim@epita.fr>
13088 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13089 trailing files, don't apply `-rf' to files which might not be
13090 created by configure (core, core.*, and *.core), but just `rm -f'.
13091 Suggested by Jonathan Kamens.
13093 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13095 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13097 2001-12-14 Akim Demaille <akim@epita.fr>
13099 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13101 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13103 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13104 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13105 abs_srcdir, top_srcpath to abs_top_srcdir.
13106 (_AC_OUTPUT_FILES): Adjust.
13107 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13108 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13109 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13111 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13113 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13114 C/Fortran linking on HP/UX, by extracting the Fortran library
13115 search path from the LPATH line in the $F77 -v output.
13117 2001-12-12 Kevin Ryde <user42@zip.com.au>
13119 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13120 forbidden file descriptors table.
13122 2001-11-26 Akim Demaille <akim@epita.fr>
13124 * bin/autoscan.in (%c_keywords): Build it at top level.
13125 Map to 1 in order to simplify its uses.
13127 2001-11-26 Akim Demaille <akim@epita.fr>
13129 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13130 Remove $filepath, useless.
13131 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13132 variables, they are really part of the tokens.
13133 Split the input line on spaces and then look for tokens.
13134 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13135 because of `lex$U.$(OBJEXT)'.
13136 (&scan_files): Use "@list" instead of join.
13137 * doc/Makefile.am (CLEANFILES): Add *.fns.
13139 2001-11-26 Akim Demaille <akim@epita.fr>
13141 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13142 Remove, replaced by...
13143 * tests/wrappl.in: Be common for all the Perl executables.
13144 In particular autoscan and autoheader want -I.
13145 * configure.ac: Adjust.
13146 * lib/autoscan/headers: errno.h is portable.
13148 2001-11-26 Akim Demaille <akim@epita.fr>
13150 * bin/autoscan.in (used): New.
13151 Use it.
13153 2001-11-26 Akim Demaille <akim@epita.fr>
13155 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13156 directives.
13157 (&scan_sh_file): Remove a duplicate pattern.
13158 (&check_configure_ac): Use long options.
13159 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13161 2001-11-26 Akim Demaille <akim@epita.fr>
13163 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13164 Before, having a line containing the opening of a multi line
13165 comment made the whole line be ignored.
13167 2001-11-26 Akim Demaille <akim@epita.fr>
13169 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13170 (testsuite Scripts): Be one of its subsection.
13171 (Autotest Logs): New.
13173 2001-11-26 Akim Demaille <akim@epita.fr>
13175 Test groups are now run two directories deeper.
13177 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13178 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13179 at_top_builddir.
13180 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13181 top_srcdir, builddir and top_builddir.
13182 Use `at_*dir' relatively to the directory containing the
13183 suite, use `*dir' when relatively to the current group dir.
13185 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13187 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13188 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13189 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13190 spelling errors.
13192 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13194 * doc/autoconf.texi (Using System Type): Add an example of `case
13195 $host' usage so people quit using `case $target' everywhere.
13197 2001-11-22 Akim Demaille <akim@epita.fr>
13199 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13200 spotted by Jim Meyering.
13202 2001-11-16 Paul Eggert <eggert@twinsun.com>
13204 This patch implements a `long double' suggestion by Oliver Kiddle.
13206 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13207 static, to catch errors if the value isn't known at compile-time
13208 and the compiler supports dynamic arrays. Change its name from
13209 `_array_' to `test_array' to avoid potential name clashes.
13210 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13211 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13212 better than double. Catch a bug in GCC 2.95.2 x86.
13213 * doc/autoconf.texi (C Compiler): Document the above.
13214 * NEWS: Likewise.
13216 2001-11-13 Akim Demaille <akim@epita.fr>
13218 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13219 hand.
13220 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13222 2001-11-13 Akim Demaille <akim@epita.fr>
13224 * lib/autotest/general.m4 (AT_INIT): After having run the test
13225 group, go back to the initial directory, not to at_suite_dir.
13227 2001-11-13 Akim Demaille <akim@epita.fr>
13229 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13230 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13231 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13232 option.
13233 (AT_CHECK_CONFIGURE): Use absolute paths.
13234 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13235 The problem is still the old one: there is no means in M4 (that I
13236 know about) to create a defining macro, because there is no means
13237 to create `$1' etc., therefore, the defining macro ``swallows''
13238 all the arguments meant to the defined macro.
13240 2001-11-13 Akim Demaille <akim@epita.fr>
13242 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13243 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13244 configure.ac.
13245 * tests/aclocal.m4: Remove, as it is no longer used.
13247 2001-11-13 Akim Demaille <akim@epita.fr>
13249 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13250 variable names when referring to a single test group, or to
13251 `suite' when referring to the whole test suite.
13252 `at_last_test' is removed: m4 compute at_format itself.
13253 (at_stdout, at_stder1, at_stderr): New variables.
13254 (AT_CHECK): Use them.
13256 2001-11-13 Akim Demaille <akim@epita.fr>
13258 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13259 in PATH.
13260 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13261 Do it as soon as a test fails, don't wait till the end of the test
13262 suite.
13263 Don't remove $as_me.[0-9]*, since these files no longer exist.
13265 2001-11-13 Akim Demaille <akim@epita.fr>
13267 * tests/tools.at: Use absolute paths, since we are no longer run
13268 in place.
13270 2001-11-13 Akim Demaille <akim@epita.fr>
13272 Now that tests are running in their own private dir, there is no
13273 need to list the files to remove at the end of tests groups.
13275 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13276 (AT_data_files, at_data_files): Remove.
13277 (AT_CLEANUP, AT_DATA): Simplify.
13278 (AT_INIT): Adjust.
13279 Remove the group dir if !debug && !failed.
13280 * tests/atspecific.m4: Adjust.
13282 2001-11-13 Akim Demaille <akim@epita.fr>
13284 Start a new layout for Autotest: `testsuite' creates
13285 `testsuite.dir' in which the at-check-line etc. files are to be
13286 found, and `testsuite.dir/003' where the test group 3 is run.
13288 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13289 at_check_line_file, at_format, at_test_normalized, at_group_dir
13290 are new variables.
13291 Create the directories.
13292 Use absolute paths for at- files.
13293 (AT_CHECK): Adjust.
13295 2001-11-11 Michael Matz <matz@kde.org>
13297 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13298 (m4_car2): New.
13299 (m4_car): Properly quote arguments.
13301 2001-11-13 Akim Demaille <akim@epita.fr>
13303 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13304 with stricter rules on LIBOBJS.
13306 2001-11-12 Paul Eggert <eggert@twinsun.com>
13308 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13309 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13310 __PROTOTYPES too.
13312 2001-11-12 Akim Demaille <akim@epita.fr>
13314 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13316 2001-11-12 Akim Demaille <akim@epita.fr>
13318 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13319 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13320 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13321 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13322 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13323 specify to what the macro should be defined (typically to 1).
13325 2001-11-12 Akim Demaille <akim@epita.fr>
13327 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13328 From Jim Meyering.
13330 2001-11-12 Akim Demaille <akim@epita.fr>
13332 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13333 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13334 definition used by Automake where LEX is +/- "${missing} lex" and
13335 `missing' itself contains variables.
13337 2001-11-12 Akim Demaille <akim@epita.fr>
13339 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13340 Now that M4sh pushes BODY, the comments were output at the end of
13341 the test suites.
13343 2001-11-08 Akim Demaille <akim@epita.fr>
13345 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13346 that we can trace macros from aclocal.m4.
13347 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13348 obsoleted, and redirect to the former anyway.
13349 Reported by Ralf Corsepius.
13351 2001-11-08 Akim Demaille <akim@epita.fr>
13353 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13354 processed only if present.
13355 * tests/torture.at (Configuring subdirectories): Use autoreconf
13356 instead of successive calls to autoconf.
13357 Add a nonexistent subdirectory to exercise the patch above.
13358 Reported by Ralf Corsepius.
13360 2001-11-08 Kevin Ryde <user42@zip.com.au>
13362 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13363 doesn't accept .S files.
13365 2001-11-07 Akim Demaille <akim@epita.fr>
13367 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
13368 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
13369 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13370 * bin/autom4te.in (warn_forbidden): New.
13371 (handle_output): Use it.
13372 Read m4_pattern_forbid with messages.
13374 2001-11-05 Akim Demaille <akim@epita.fr>
13376 * bin/autom4te.in (--normalize): Remove.
13377 * lib/autom4te.in: Adjust.
13379 2001-11-05 Akim Demaille <akim@epita.fr>
13381 * tests/Makefile.am (testsuite): Rename this target as...
13382 ($(TESTSUITE)): this.
13383 From Nicolas Joly.
13385 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13387 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13388 the --prefix option, also remove it's argument.
13390 2001-11-05 Akim Demaille <akim@epita.fr>
13392 * doc/autoconf.texi (testsuite Invocation): Update.
13393 (Writing testsuite.at): Update.
13395 2001-11-03 Akim Demaille <akim@epita.fr>
13397 * doc/autoconf.texi: s/@code/@command/ where appropriate.
13399 2001-11-03 Akim Demaille <akim@epita.fr>
13401 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13402 (&file_name_is_absolute): New, wrappers around routines from
13403 File::Spec.
13404 Use and export them.
13405 (&find_configure_ac): Optionally take a directory where to look at.
13406 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13407 the arguments.
13408 Default @ARGV to `.', not find_configure_ac.
13409 (&autoreconf): Argument is a directory.

13416 (@export_forward_subs): New.
13417 Add basename, dirname, and fileparse.
13418 (@EXPORT): Adjust.
13419 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13420 Don't look for aclocal flags if we already know aclocal is not
13421 used.
13422 Move aclocal.m4t only if it exists.
13423 Reported by Ezra Peisach.
13425 2001-11-03 Akim Demaille <akim@epita.fr>
13427 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13428 passed on command line, defaulting to ./configure.ac if present.
13429 (&maybe_autoreconf, File::Find): Remove, unused.
13430 (&autoreconf): If autoconf is not used, don't try to trace.
13432 2001-11-02 Akim Demaille <akim@epita.fr>
13434 * configure.ac: Bump to 2.52g.
13436 2001-11-02 Akim Demaille <akim@epita.fr>
13438 Version 2.52f.
13440 2001-11-02 Akim Demaille <akim@epita.fr>
13442 * config/config.guess, config/config.sub, doc/standards.texi:
13443 * config/lispdir.m4: Update from masters.
13444 * configure.ac: Bump to 2.52f.
13446 2001-11-02 Akim Demaille <akim@epita.fr>
13448 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13449 Don't run aclocal when aclocal.m4 is not from aclocal.
13450 From Ezra Peisach.
13451 Don't run libtoolize and gettextize if --install is not given.
13453 2001-11-01 Paul Eggert <eggert@twinsun.com>
13455 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13456 be invoked before _AS_LINENO_PREPARE.
13457 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13458 than character ranges.
13460 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13461 invoking AS_BASENAME. Set the locale variables to 'C' if
13462 possible, as POSIX requires this to get the traditional
13463 behavior.
13464 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13466 2001-10-31 Paul Eggert <eggert@twinsun.com>
13468 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13469 with {}, as that triggers a bug in Bash 2.05.
13471 (_AS_LINENO_PREPARE): Use Sed rather than
13472 Awk. Fix the sed prepass to work even if there are multiple
13473 instances of $LINENO on the same line. Do not substitute for
13474 other variables like $LINENOT. Do not check file dates; such a
13475 check is unreliable on sufficiently fast machines, and removing
13476 the check makes the code simpler and more reliable. Check for
13477 output and chmod failures.
13479 * doc/autoconf.texi (Special Shell Variables): Document
13480 the above.
13482 2001-10-31 Akim Demaille <akim@epita.fr>
13484 * tests/Makefile.am (atconfig): Remove this target, Automake
13485 handles it now.
13487 2001-10-31 Akim Demaille <akim@epita.fr>
13489 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13490 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13491 provided, while it is optional.
13492 * configure.ac: Adjust.
13494 2001-10-26 Paul Eggert <eggert@twinsun.com>
13496 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13497 lib/Autom4te/Struct.pm:
13498 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13499 with 5.005_02.
13501 * doc/autoconf.texi (Special Shell Variables): Document some
13502 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13504 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13505 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13506 eval $LINENO is not portable in practice.
13508 2001-10-24 Akim Demaille <akim@epita.fr>
13510 * lib/Autom4te/General.pm (backname): New.
13512 2001-10-24 Akim Demaille <akim@epita.fr>
13514 * m4/: Remove, merged into...
13515 * config/: here.
13517 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
13519 * doc/autoconf.texi (Shellology): Mention the problems with bash
13520 2.05's use of ANSI quoting in its `set' builtin.
13522 2001-10-22 Paul Eggert <eggert@twinsun.com>
13524 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13525 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13526 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13527 POSIX decided to standardize on the int flavor of strerror_r.
13528 Always do char* test, as there's no reason not to.
13529 Assign to a char* var, to catch strerror_r that returns int*.
13531 * doc/autoconf.texi (Particular Functions):
13532 Document the above changes. Also, document the fact that
13533 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13535 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13537 2001-10-20 Akim Demaille <akim@epita.fr>
13539 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
13540 the executable was missing from the log.

13544 * lib/Autom4te/General.pm (&update_file): If destination is
13545 unchanged, remove the source.
13546 (&up_to_date_p): Don't be verbose, be debug.
13547 * bin/autoreconf.in: No longer support --m4dir.
13548 (&autoreconf): Display the full path of the configure.ac we are
13549 studying.
13550 Trace it only once.
13551 Be sure to honor --force with gettextize.
13552 Always run aclocal.
13553 * doc/autoconf.texi: Adjust.
13555 2001-10-20 Akim Demaille <akim@epita.fr>
13557 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13558 Remove, dead.
13559 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13560 `intl' is already present, as it refuses unless --force.
13561 (&parse_args): Use -I, --include instead of the old Autoconf
13562 options.
13563 ($localdir, $autoconf_dir): Remove.
13564 (@include): New.
13565 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13567 2001-10-19 Jens Petersen <petersen@redhat.com>

13575 file in @configure_input@.
13576 Don't mention `automatically' in addition to `generated'.
13577 * tests/torture.at (#define header templates): Adjust.
13579 2001-10-19 Akim Demaille <akim@epita.fr>
13581 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
13582 comment, explain how to install automatic mode selection.
13583 From Russ Allbery.
13585 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
13587 * bin/autoreconf.in (autoreconf): Display the path to the
13588 configure.ac being studied.
13590 2001-10-18 Paul Eggert <eggert@twinsun.com>
13592 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13593 long, to work around a bug in the HP C compiler version HP92453-01
13594 B.11.11.23709.GP.
13596 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13597 (AS_BASENAME_EXPR): New macro.
13598 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13599 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13600 and fall back on 'sed' only if the other two fail. This makes
13601 AS_BASENAME act more like AS_DIRNAME.
13602 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13603 contains white space.
13604 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13605 Use AS_DIRNAME, since I think it's now DOS-friendly.
13606 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
13607 Allow "dirname //FOO" to return either / or //, as POSIX allows
13608 either behavior.
13610 2001-10-10 Akim Demaille <akim@epita.fr>
13612 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
13613 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
13614 From Eric Sharkey.
13616 2001-10-10 Akim Demaille <akim@epita.fr>
13618 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
13619 m4_define, since...
13620 (_AS_ECHO_N): AS_REQUIREs it.
13622 2001-10-10 Akim Demaille <akim@epita.fr>

13658 bother with $force since...
13659 * lib/Autom4te/General.pm: does.
13661 2001-10-08 Akim Demaille <akim@epita.fr>
13663 * bin/autoreconf.in: Rewrite in Perl.
13664 * configure.ac: Adjust.

13713 2001-10-08 Akim Demaille <akim@epita.fr>
13715 Use `add-log-current-defun-function' for ChangeLog creation.

13736 * tests/base.at: Adjust the tests to use AS_INIT.
13737 * tests/tools.at (AT_DATA_FORBIDDEN): New.

13748 empty, and if we can find a shell that does support LINENO,
13749 then set CONFIG_SHELL to that shell and then re-execute
13750 ourselves with CONFIG_SHELL.
13752 2001-10-05 Paul Eggert <eggert@twinsun.com>
13754 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
13755 doesn't exist. Remove *.tmp, as a .tmp file is created during the
13756 build of $(TESTSUITE).
13758 2001-10-05 Akim Demaille <akim@epita.fr>
13760 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

13802 instead of exec'ing to preserve $0 and $@.
13804 2001-10-01 Akim Demaille <akim@epita.fr>
13806 * tests/testsuite (AT_INIT) <at_pass_list>: New.

13825 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
13826 Don't use nested parenthesization. This patch was originally
13827 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
13828 but somehow it didn't get incorporated then.
13829 * doc/autoconf.texi (Limitations of Usual Tools):
13830 Clarify remark about sed and nested parenthesization.
13832 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
13833 Report an error if the size cannot be determined even though
13834 the type exists.
13835 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13836 Check for `expr' arithmetic overflow, and for compilation failure,
13837 and invoke a new argument $4 if either is discovered.
13838 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13839 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
13841 2001-09-28 Akim Demaille <akim@epita.fr>

13861 status when executing the ACTION-IF-FALSE.

13881 Raja R Harinath:

13935 * doc/autoconf.texi (Common Shell Constructs): Rename as...

13982 2001-09-22 Akim Demaille <akim@epita.fr>
13984 Rely on `$LINENO' when possible instead of `__oline__'.
13986 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
13987 `$LINENO' support replacement when not supported.
13988 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
13989 them explicitly to be sure they are not output before this section

13999 character (u: -> ue) in a code comment.
14000 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
14001 it works.
14003 2001-09-21 Akim Demaille <akim@epita.fr>

14006 Suggested by Jim Meyering.
14008 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14010 * lib/autoconf/programs.m4: Use extensions listed in
14011 $ac_executable_extensions when looking for programs.

14015 * lib/autoconf/general.m4: Fix a small Englisho.

14023 PATH_SEPARATOR.
14024 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

14027 * lib/autotest/general.m4: Replace occurrences of ':' in

14030 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14032 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14033 arguments. Fixed a typo.
14035 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14037 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

14040 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14042 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
14043 * bin/autoupdate.in: Ditto.
14044 * bin/autoheader.in: Reworded a few comments.
14045 * bin/autoconf.in: Reworded help text for a few options.

14049 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14051 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14052 already have $file). Set output files to binary mode (helps avoid
14053 CR issues on DOSish systems).
14055 2001-09-19 Akim Demaille <akim@epita.fr>
14057 * lib/autotest/general.m4: Englishoes.
14058 From Tim Van Holder and Alexey Mahotkin.
14060 2001-09-18 Paul Eggert <eggert@twinsun.com>
14062 * doc/autoconf.texi (Common Shell Constructs): New node,
14063 documenting AS_DIRNAME.
14064 (Limitations of Usual Tools): Refer to it when discussing dirname.
14065 Also, update discussion of POSIX standard to reflect latest draft.
14067 * lib/autoconf/c.m4:
14068 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14070 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14071 Do not pass a first argument with leading '-'
14072 to expr, by parenthesizing initial integers that might be negative.
14074 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14075 now merely checks whether it is an error to pass an argument
14076 to getpgrp.
14078 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14079 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14080 whether it is a (compile-time) error to pass an argument to
14081 getpgrp. This simpler test supports the revised documentation,
14082 and is all that AC_FUNC_GETPGRP's users really need.
14084 2001-09-18 Akim Demaille <akim@epita.fr>
14086 * doc/autoconf.texi (Limitations of Make) <$<>: New.
14088 2001-09-18 Akim Demaille <akim@epita.fr>

14096 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14097 correctly.
14098 Add test for AS_BASENAME.
14099 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14100 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14101 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14102 * tests/base.at: Fixed the expected responses. The old ones were
14103 one line out...
14104 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14105 the documentation claims it should (and how it behaved in 2.13).
14107 2001-09-18 Akim Demaille <akim@epita.fr>
14109 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14110 the AC_CONFIG_COMMANDS invocation.
14111 This also solves the name clash problems.
14112 Don't set the package's ID.
14113 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14114 No longer to be shipped.
14115 (version.in): Remove.
14116 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14117 * lib/autoconf/status.m4: Adjust.
14118 Use `m4_PACKAGE_STRING'.
14119 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14120 the only optional argument is the name of the test suite.
14121 Expect `package.m4' to define the package signature.
14122 * lib/autom4te.in (Autotest): Add `package.m4?'.
14123 * tests/Makefile.am (package.m4): New.
14124 * tests/suite.at: ifnames is a victim.
14126 2001-09-18 Akim Demaille <akim@epita.fr>
14128 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14129 AC_LIBSOURCE, AC_CONFIG_FILES.
14130 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14131 program version string doesn't match the package's.
14132 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14133 after `(cached)'.

14137 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14138 Allow expression to return any value that can fit into unsigned long
14139 (not int, as before). Check for output errors.
14141 2001-09-17 Bruno Haible <haible@ilog.fr>
14143 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14144 Always include <stdio.h> and <stdlib.h>. Evaluate
14145 the expression in an extra function before these includes. Call
14146 fprintf "%d" only after ensuring the argument is of type 'int'.
14147 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14149 2001-09-17 Paul Eggert <eggert@twinsun.com>
14151 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14152 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14153 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14154 when they don't exist.
14156 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14157 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14158 need it.
14160 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14161 version with the version used by fileutils 4.1, except use
14162 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14163 we don't need it.
14165 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14167 2001-09-13 Akim Demaille <akim@epita.fr>
14169 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
14170 _first_.
14171 Reported by Gerrit P. Haase.
14173 2001-09-13 Akim Demaille <akim@epita.fr>
14175 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
14176 m4_defn'ing is valid.

14182 Use it.

14190 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
14191 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
14192 Likewise.

14194 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
14195 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
14196 AT_tests_all for consistency.
14197 Set at_victims.
14198 (AT_VICTIMS): Similar to AT_KEYWORDS.
14199 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.

14203 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
14205 2001-09-13 Akim Demaille <akim@epita.fr>
14207 * lib/autotest/general.m4 (AT_INIT): Create and remove
14208 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14209 test suites can cohabit.
14211 2001-09-13 Akim Demaille <akim@epita.fr>
14213 * tests/mktests.sh: Don't output banners for empty test files.
14215 2001-09-13 Akim Demaille <akim@epita.fr>
14217 Test suites can be run independently of configure.

14232 (Syntax of the shell scripts): Don't check ifnames.
14233 (AT_CHECK_PERL_SYNTAX): New.
14234 (Syntax of the Perl scripts): Check ifnames.

14259 (m4_list_append): Remove.
14261 Spread a few keywords in the Autoconf test suite.
14263 2001-09-10 Akim Demaille <akim@epita.fr>
14265 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

14285 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package

14298 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
14299 in addition, it introduces useless differences in logs.
14300 (AT_INIT): Let atconfig and atlocal be both optional.
14301 Adjust PATH computation.
14302 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.
14304 2001-09-07 Akim Demaille <akim@epita.fr>
14306 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon
14307 m4sugar/version.m4.
14309 2001-09-05 Akim Demaille <akim@epita.fr>
14311 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'

14313 From Uwe Seimet.
14315 2001-09-05 Akim Demaille <akim@epita.fr>
14317 * bin/autom4te.in: --language is -l, not -s.
14319 2001-09-05 Akim Demaille <akim@epita.fr>
14321 Be ready to handle filenames as stupid as `dnl.at', for if even
14322 the maintainer is dumb enough to do that...
14324 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14325 excellence in M4 quotation: consider `__file__' is active.
14327 And BTW, when invoking m4, pass the --include in the right order:
14328 the wrong one.
14330 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
14331 4m.
14333 2001-09-05 Akim Demaille <akim@epita.fr>
14335 * lib/Autom4te/XFile.pm: New lib file.
14336 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
14337 * bin/autoheader.in: Use it.
14339 2001-09-05 Akim Demaille <akim@epita.fr>
14341 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff
14342 defined.

14349 * bin/autoscan.in: Use `getopt' and `find_files' etc.
14350 Add -I, --include support.
14351 * doc/autoconf.texi (autoscan Invocation): Adjust.
14353 2001-09-05 Akim Demaille <akim@epita.fr>
14355 CVS GNU M4 doesn't like `undefine(undefined)'.
14357 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
14358 New, extracted from main.
14359 Use IO::File wherever possible.
14360 (input.m4): Be constant, use -I instead of hard coding $tmp.
14361 Therefore be a quoted heredoc.
14362 Don't invoke `_au_disable', since ac was not loaded, but just
14363 `unm4.m4'.
14365 2001-08-31 Akim Demaille <akim@epita.fr>
14367 Version 2.52d.
14369 2001-08-31 Akim Demaille <akim@epita.fr>
14371 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
14372 previous patch.
14373 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
14375 2001-08-31 Akim Demaille <akim@epita.fr>
14377 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
14378 serious problems handling heredocs in heredocs.
14379 Reported by Nicolas Joly.
14381 2001-08-31 Akim Demaille <akim@epita.fr>
14383 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
14384 (Making testsuite Scripts): Update.
14386 2001-08-31 Akim Demaille <akim@epita.fr>
14388 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
14390 2001-08-31 Akim Demaille <akim@epita.fr>
14392 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
14393 (testsuite Scripts): There is no such thing as `atconfig.in'.
14394 And actually one diagram is missing: test suite runtime.
14396 2001-08-31 Akim Demaille <akim@epita.fr>
14398 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
14399 inverse order.
14401 2001-08-31 Akim Demaille <akim@epita.fr>
14403 * bin/autoupdate.in (@include): `installcheck' revealed the path
14404 to m4sugar was lacking!
14406 2001-08-31 Akim Demaille <akim@epita.fr>
14408 * man/Makefile.am (.x.1): We really have to pass
14409 autom4te_perllibdir.
14411 2001-08-31 Akim Demaille <akim@epita.fr>
14413 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
14414 debug scripts, in particular passing explicitly listed tests to
14415 run is stupid.
14417 2001-08-31 Akim Demaille <akim@epita.fr>
14419 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
14420 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
14421 Use directly autom4te, not autoconf.
14422 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
14424 2001-08-31 Akim Demaille <akim@epita.fr>
14426 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
14427 * bin/autoheader.in (%symbol): Strip arguments of macros.

14433 2001-08-31 Akim Demaille <akim@epita.fr>
14435 * bin/autom4te.in (&parse_args): Die on unknown languages.
14436 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
14437 need for autoconf.
14438 Promote --include over --macrodir and other obsolete options.
14440 2001-08-31 Akim Demaille <akim@epita.fr>
14442 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
14443 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
14444 * bin/autom4te.in ($autoconf): Pass --force.
14445 `print $out' doesn't print `$_' but `$out'.
14446 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
14447 (autoheader): Pass --force since the test suite goes too fast for
14448 the time stamps.
14449 Adjust to the new autoheader messages.
14451 2001-08-31 Akim Demaille <akim@epita.fr>
14453 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
14454 Check the completeness of the #template.
14455 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
14456 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
14457 invocation.
14459 2001-08-31 Akim Demaille <akim@epita.fr>
14461 * lib/Autom4te/General.pm (&find_file, &update_file): New.
14462 * bin/autoupdate.in, bin/autoheader.in: Adjust.
14463 Drop AC_MACRODIR dead for real.
14464 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14465 `autoheader: `config.hin' is created'.
14466 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14468 2001-08-31 Akim Demaille <akim@epita.fr>
14470 * bin/autoheader.in: Rewrite in Perl.
14471 * tests/autoheader: Adjust.
14473 2001-08-31 Akim Demaille <akim@epita.fr>
14475 * bin/autoconf.in (--include, -I): New option.
14476 Map --localdir, --autoconf-dir onto it.
14477 Forward autom4te's options instead of interpreting them.
14478 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14479 There is no such envvar since the inception of autom4te.cfg.
14480 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14481 * bin/autoupdate.in: Adjust, and perform more control.
14482 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
14483 * tests/autoconf: Dittowise.
14485 2001-08-31 Akim Demaille <akim@epita.fr>
14487 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
14488 * bin/autom4te.in (&find_file): Support `FILE?' standing for
14489 optionally `FILE'.
14490 Use -e, not -f, since /dev/null for instance is OK.
14491 (&parse_args): Adjust.
14492 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
14494 2001-08-31 Akim Demaille <akim@epita.fr>
14496 * configure.ac: Also find tested executables in bin.
14497 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
14498 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
14499 installed peer executables, only PATH is allowed to resolve it.
14500 Pass `autoconf_dir' via options, not via invisible envvars.
14501 * lib/Autom4te/General.pm (&find_peer): Remove.
14502 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14503 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14504 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14505 find the executables for it.
14506 * tests/Makefile.am: Major cleanup. Too lazy to document...
14507 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14508 We only need PERL.
14509 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14510 indeed related to running the test suite, while passing
14511 --autoconf-dir and others is related to running non installed
14512 Autoconf executables. So don't do that, leave it to...
14513 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14514 * tests/autoscan: New.
14515 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
14516 refer to library files: rely on --language.
14518 2001-08-29 Akim Demaille <akim@epita.fr>
14520 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
14521 s/--set/--language/.
14523 2001-08-29 Akim Demaille <akim@epita.fr>
14525 * doc/autoconf.texi: Strip the @nodes.
14526 Suggested by Paul Eggert.
14527 (Initializing configure): Typo.
14529 2001-08-29 Akim Demaille <akim@epita.fr>
14531 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
14532 Suggested by Paul Eggert.
14534 2001-08-29 Akim Demaille <akim@epita.fr>
14536 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
14537 download in a tmp dir.
14539 2001-08-29 Akim Demaille <akim@epita.fr>
14541 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
14542 case insensitive OSes out there :(
14543 From Tim Van Holder.
14545 2001-08-29 Akim Demaille <akim@epita.fr>
14547 * lib/autom4te.in: New.
14548 * lib/Makefile.am (edit, autom4te.cfg): New.
14549 * bin/autom4te.in (BEGIN): Simplify.
14550 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
14551 (&load_configuration): New. Use it.
14552 (&parse_args): Support --mode, --set, and --melt.
14553 * bin/autoconf.in: Simplify and adjust.
14554 * tests/Makefile.am (AUTOMAKE): Use --set.
14555 * tests/atlocal.in: Adjust.
14556 * BUGS: distcheck and check are weak.
14558 2001-08-29 Akim Demaille <akim@epita.fr>
14560 * lib/autotest/general.m4: Use
14561 foo=`(command) 2>/dev/null`
14562 not
14563 foo=`command` 2>/dev/null
14564 (at-devnull): Rename as...
14565 (AT-devnull): this.
14566 (--clean): Remove AT-* files too.
14567 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
14568 Reported by Nicolas Joly.
14570 2001-08-28 Akim Demaille <akim@epita.fr>
14572 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
14573 quotes inside single quotes.
14574 Reported by Nicolas Joly.
14576 2001-08-28 Kevin Ryde <user42@zip.com.au>
14578 * doc/autoconf.texi (Function Portability): Mention C right shifts.
14580 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
14582 * lib/autotest/general.m4: Reword some messages.
14583 (AT_INIT): Check for the `times' builtin before using it.
14584 Support test ranges as arguments to the testsuite.
14585 Have -e imply -d as the help text suggested.
14587 2001-08-27 Akim Demaille <akim@epita.fr>
14589 * Makefile.maint: Formatting changes.
14590 (do-po-update, po-update, cvs-update, update): New targets.
14591 (AMTAR): Remove.
14593 2001-08-27 Akim Demaille <akim@epita.fr>
14595 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

14598 <AUTOTEST_PATH>: May contain absolute dir names.
14600 2001-08-27 Akim Demaille <akim@epita.fr>
14602 * lib/autotest/general.m4 (AT_INIT): Log the command line.
14603 Support `VAR=VAL' as arguments.
14604 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
14605 may be set via the command line.
14607 2001-08-27 Akim Demaille <akim@epita.fr>
14609 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
14610 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
14611 first the build dirs, then the src dirs.
14612 * configure.ac (AC_CONFIG_TESTDIR): Adjust.
14614 2001-08-27 Akim Demaille <akim@epita.fr>
14616 * lib/autotest/general.m4 (AT_INIT): Output the definition of

14621 2001-08-27 Akim Demaille <akim@epita.fr>
14623 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
14624 `ac_top_builddir' to mimic Automake's vocabulary, which much more
14625 readable.
14626 Adjust callers.
14627 * doc/autoconf.texi (Configuration Actions): Document the vars
14628 available in commands.
14629 Emphasize the risks of collisions in init-cmds.

14633 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
14634 (Initializing configure): this new node.
14636 2001-08-27 Akim Demaille <akim@epita.fr>

14649 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move
14650 to...
14651 * lib/autoconf/autoheader.m4: this new file.
14652 * lib/autoconf/general.m4 (AH_OUTPUT, AH_VERBATIM)

14659 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
14660 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
14661 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
14662 -> ac_dir).
14663 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
14664 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
14666 2001-08-27 Akim Demaille <akim@epita.fr>

14691 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
14692 (AMTAR): Help automake define it.
14693 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
14694 needed, 1.5 can have a macro and a target with the same name.
14695 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
14696 * m4/strip.m4: New.

14709 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
14710 Adjust callers.
14711 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
14712 the name of the directory they're in, instead of the filename,
14713 since version.m4 is now in m4sugar, but m4_acversion must not be
14714 classified as an Autoconf macro.
14715 ($input_m4): Don't qualify the path to m4sugar.
14716 Rather, pass autoconf_dir to m4.
14717 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
14718 * tests/suite.at: Require 2.52c.
14720 2001-08-27 Akim Demaille <akim@epita.fr>

14732 of config.log on traps.
14733 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
14734 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
14735 for config.status'.
14736 Open the log as soon as possible.
14737 Use the same log introduction as configure's.
14739 2001-08-22 Paul Eggert <eggert@twinsun.com>
14741 * doc/autoconf.texi (Indices): New node.
14742 Move indices out of the top level menu and into this submenu.
14744 2001-08-22 Akim Demaille <akim@epita.fr>
14746 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
14747 AC_TRY_COMMAND.

14801 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
14802 * NEWS, README, README-alpha, TODO, tests/README: This package is
14803 `Autoconf', not `autoconf' (the executable).
14805 2001-08-20 Akim Demaille <akim@epita.fr>
14807 Info readers seem to need `Index' in the index node title :(
14809 * doc/autoconf.texi: Reverse the 2001-08-15 change which
14810 simplified index node names.
14812 2001-08-20 Akim Demaille <akim@epita.fr>

14854 2001-08-20 Akim Demaille <akim@epita.fr>
14856 Huh!?!?! There are still some user EOF tags used, which prevents
14857 their use in AC_CONFIG_COMMANDS for instance...
14859 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
14860 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

14923 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
14924 `$0.log' as for projects where testsuite is in src, we'd have
14925 testsuite.log created in src.

14939 2001-08-17 Akim Demaille <akim@epita.fr>
14941 * doc/autoconf.texi: Work around Texinfo buglets.
14942 (Transformation Rules): One example is enough, users are expected
14943 to have their brains on. And BTW, use DESTDIR.
14944 (dvar): New macro. Use it.
14946 2001-08-17 Akim Demaille <akim@epita.fr>
14948 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

14954 * bin/autom4te.in: --normalize is a new option.
14955 * bin/autoconf.in: Use it.

14981 * doc/install.texi: Use @command.

14988 value.
14989 From Kevin Ryde.
14991 2001-08-15 Akim Demaille <akim@epita.fr>
14993 * Makefile.maint (CVS): New.
14994 (local-check): Run changelog-check. last.
14995 (alpha): Don't depend upon local-check, since...
14996 (cvs-dist): depends upon it.
14998 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
15000 * tests/Makefile.am: Use a clean-local rule to remove
15001 autom4te.cache (it's a directory, not a file.
15002 * Makefile.am: Ditto (but maintainer-clean-local).
15004 2001-08-15 Akim Demaille <akim@epita.fr>
15006 * bin/autom4te.in (@m4_warning): New.
15007 (&handle_m4): Use it.
15008 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15009 warnings are issued at each run.
15010 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15011 is in the src tree.
15013 2001-08-15 Akim Demaille <akim@epita.fr>
15015 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
15016 don't waste time running `autoupdate --version' works.
15017 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
15019 2001-08-13 Akim Demaille <akim@epita.fr>
15021 * doc/autoconf.texi (ma): Rename this index as...

15035 duration of the test suite.
15037 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
15039 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
15040 endianness for comparison instead of relying on AT_CHECK_ENV.
15042 2001-08-11 Paul Eggert <eggert@twinsun.com>
15044 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
15045 to the INSTALL file.
15047 2001-08-11 Paul Eggert <eggert@twinsun.com>

15072 * tests/mktests.sh: Update year in copyright notice.
15074 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
15076 * tests/semantics.at (AC_C_BIGENDIAN): New test.
15078 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15080 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15081 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15082 * doc/autoconf.texi (C Compiler Characteristics): Update
15083 documentation for AC_C_BIGENDIAN.
15085 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15087 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15088 magic values from an object file when cross-compiling.
15089 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15091 2001-08-10 Akim Demaille <akim@epita.fr>
15093 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15094 effects.
15095 Suggested by Russ Allbery.
15097 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15099 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15100 current $prefix to the sub-configures.
15102 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15104 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15105 extension (needed on BeOS). Reported by Guido van Rossum.
15107 2001-08-09 Akim Demaille <akim@epita.fr>
15109 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15111 2001-08-07 Akim Demaille <akim@epita.fr>
15113 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15114 removed.
15115 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15116 No need to remove the files before and after the each test, before
15117 each test and at the end of the suite is enough.
15118 Display only the children `times', not the shell's.
15119 If the test failed or was skipped, at-times is not available.
15121 2001-08-07 Akim Demaille <akim@epita.fr>
15123 Always produce testsuite.log, including when there are no
15124 failures. This helps getting information on skipped tests, and
15125 duration of the tests. Err, implement the latter btw.
15127 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15128 Dump information on the first run of each test.
15129 (AT_CLEANUP): Create `at-times' containing the duration of the
15130 test group.
15132 2001-08-07 Akim Demaille <akim@epita.fr>
15134 The use of `dumpstat' revealed that `len' was used although it
15135 should not. m4_text_wrap was using it, but in the Autoconf world
15136 where it is legal. Hence (i) test M4sh in its own world, not
15137 Autoconf's, and (ii), ahem, fix the bug :)
15139 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15140 does not like `' instead of [].
15141 (AT_INIT): Forbid `^_?AT_'.
15142 And don't output such tokens.
15143 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15144 `script.as', and `autom4te.cache'.
15145 Remove `empty' and `macro' which are no longer used.
15146 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15147 * tests/m4sugar.at: Use it.
15148 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15150 2001-08-07 Akim Demaille <akim@epita.fr>
15152 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15154 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15156 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15158 2001-08-04 Akim Demaille <akim@epita.fr>
15160 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15161 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15162 AC_TRY_LINK.
15163 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15164 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15165 (AC_F77_MAIN): Likewise.
15167 2001-08-04 Akim Demaille <akim@epita.fr>
15169 Don't rely on M4sugar outputting the patterns in files, since we
15170 might process the output _without_ running m4, hence without these
15171 files.
15173 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15174 * bin/autom4te.in (@Request::includes): Remove, unused.
15175 (@Request::source): Rename as...
15176 (@Request::input): this.
15177 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15178 (&handle_output): Fetch the patterns from the traces.
15179 `$forbidden' and `$allowed' are constant: use m//o.
15180 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15181 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15183 2001-08-04 Akim Demaille <akim@epita.fr>
15185 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15186 autoconf', i.e., in addition to caching traces, cache the output.
15188 * bin/autom4te.in (Request::cache): Rename as...
15189 (Request::id): this.
15190 ($cache, $icache, $tcache, $ocache): New.
15191 (&handle_m4): Save M4 output in the cache instead of $tmp.
15192 (&handle_output): Adjust.
15193 (&up_to_date_p): Check that the output cache is up to date too.
15194 (top level): Run `&handle_m4' iff force or the cache is invalid.
15195 Run `&handle_output' if the output cache is more recent.
