986 The test suite did not cover this bug because the code was not
987 quoting properly the arguments of `rm -f' (which "fails" silently)
988 as well as the arguments of `diff' (whose output was redirected to
989 /dev/null so we couldn't see its error message).

1089 regression in sourcing files.
1090 * tests/autotest.at (Using atlocal): New test to catch this.

1112 <PARSE_ARGS>: Parse new option.
1113 <HELP_TUNING>: Document it.
1114 * tests/autotest.at (Choosing where testsuite is run): New test
1115 for this feature.
1116 (Keywords and ranges): Add test for missing -k argument.
1117 * NEWS: Document this.
1118 * doc/autoconf.texi (testsuite Invocation): Likewise.
1120 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1122 * build-aux/config.guess, build-aux/config.sub,
1123 build-aux/texinfo.tex: Sync from gnulib.

1133 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1135 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1136 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1137 mode, we change to the source directory, also set $ac_pwd so we
1138 do not go back to the build tree for the next config subdir.

1140 config subdirs on the top level.
1142 Fix parallel `maintainer-check'.

1203 Optimize AC_REQUIRE.
1204 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1205 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1206 (m4_require): Avoid extra macro calls.
1208 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1210 * tests/torture.at (srcdir): Fix quoting.
1212 Do not pass top_srcdir to configure scripts in testsuite.
1213 * tests/autotest.at (srcdir propagation): Copy install-sh to
1214 source tree.
1215 (my only test): Drop setting of `top_srcdir'.
1216 * tests/base.at (Input/Output): Likewise.
1217 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1218 config.guess, and config.sub to test source tree.

1230 Quote $abs_top_srcdir in tests.
1231 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1232 * tests/tools.at (Syntax of the shell scripts): Likewise.
1234 * tests/m4sh.at (LINENO): Quote $0.
1236 Fix testsuite program wrapper for whitespace in `pwd`.
1237 The problem here is that the usual mantra is that command
1238 variables can contain arguments, thus we cannot just escape
1239 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1240 $top_builddir/tests directory early in $PATH, so that the
1241 wrappers are found by their plain name.
1242 * tests/wrapper.as: Put $testdir early in $PATH.
1243 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1245 Proper config.status --file/--header and $srcdir escaping.

1256 Quote $at_group_dir.
1257 * tests/autotest.at (whitespace in absolute testdir): New test.
1259 * lib/autom4te.in: Quote @datadir@.
1261 Proper file name escaping in Autoconf programs and Perl modules.
1262 This includes escaping of characters special to the shell
1263 as well as special to Perl, e.g., leading `<' or `>'.
1264 For example, when $file starts with `>', `open ">$file"'
1265 wrongly tries to append to a different file.
1266 * bin/autoconf.as: Fix quoting for autom4te options.
1267 * lib/Autom4te/General.pm (shell_quote): New function, taken
1268 from coreutils, written by Jim Meyering.
1269 (mktmpdir): Use it.

1273 * bin/autoscan.in (main): Likewise.
1274 * bin/autoupdate.in (main): Likewise.
1275 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1276 * bin/ifnames.in: Likewise, XFile usage fixes.
1277 * tests/tools.at (autom4te and whitespace in file names): Extend
1278 test. Test twice, with special characters allowed on w32, and the
1279 rest. Test leading and trailing whitespace, for `open_quote'.
1280 (autotools and whitespace in file names): New, analogous test.
1281 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1282 by Russ Allbery and Eric Blake.
1284 Sync from Automake.
1285 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1286 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1287 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1288 (update_file, contents): Use it.
1290 * Makefile.am (autom4te-update): Rewrite for git.
1292 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1294 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1296 Fix copyright years.

1304 * build-aux/config.sub: Likewise.
1306 When using older automake, don't downgrade build-aux/texinfo.tex.
1307 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1308 * doc/Makefile.am (TEXINFO_TEX): Add.
1310 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1312 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1313 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1314 #undef as this runs afoul of our new way of creating config.h.
1315 Problem reported by Jim Meyering in
1316 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
1318 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1320 Fix autom4te for unusual characters in input file names.
1321 * bin/autom4te.in (files_to_options): Quote active characters
1322 for the shell.
1323 * tests/tools.at (autom4te and white space in file names):
1324 New test.
1326 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1327 Document that Tru64 awk always splits $0.
1329 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1331 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1332 `#AT_STOP_...' line at the end of each test.
1334 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1336 * lib/autotest/general.m4 (AT_INIT): For awk line number
1337 extraction script, ensure `$at_group' has a defined value
1338 even for the empty set, and properly quote its usage inside
1339 the awk script.
1341 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1343 * doc/autoconf.texi (Shell Functions): New chapter. Document
1344 IRIX sh $0 issue in functions, move content from ...
1345 (Portable Shell): ... here.
1346 (Shell Script Compiler): Note that shell functions are not
1347 totally unportable any more.
1349 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1350 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1352 * lib/autotest/general.m4 (AT_INIT): Exit awk script after

1358 Fix quoting.
1360 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1362 Fix IRIX testsuite debugging failures: $0 in functions.
1363 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1364 Do not use $0 inside a function, as IRIX sh will set that to the
1365 function name rather than the script invocation name.
1367 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1368 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1370 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1371 to extract test scripts.
1372 (AT_INIT): Extract and cache test script line numbers.
1374 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1376 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1377 subsequent fixups; the awk -> here-document conversion trashes
1378 performance too much with AIX sh.
1380 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1382 * tests/local.at: Do not test m4, perl with AT_TESTED.
1384 Diagnose and guard against write errors dealing with config.status.
1385 The general idea is this: all write failures from `configure'
1386 writing `config.status' are indicated by $ac_write_error, which
1387 is only checked at the end. This is safe because config.status
1388 code is not executed before the file is complete. Other write
1389 failures, be they inside config.status, or in sub shell/awk
1390 scripts spawned from configure or config.status, typically need
1391 earlier checking, as their results are used right afterwards.
1392 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1393 before writing config.status, check afterwards.
1394 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1395 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1396 Set `ac_write_error' for write failures to config.status. Barf
1397 upon write failures to temporary files.
1398 Adjust note about closing and reopening the here-document.
1399 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1400 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1401 reopening the here-document.
1402 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1403 Ensure `ac_write_error' does not escape into config.status.
1404 Also, add a couple of code paths not yet exercised in the test
1405 suite: a config file with input from stdin, and a config header
1406 output to stdout.
1407 Suggestion for catching write errors by Bruno Haible.
1409 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1411 Avoid error with Tru64 awk and testsuite lines with many words.
1412 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1413 reads the testsuite, set the field separator to an unusual value,
1414 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1415 even splits the input if $i, i>0, was never accessed in the script.
1417 Revert 2007-10-17 change.
1418 * TODO: Multiline args in config files and headers mean something
1419 different and are not fixed, see
1420 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
1421 Report by Stepan Kasal.

1425 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1427 AC_*_TOOL does not canonicalize the prefix
1428 * doc/autoconf.texi (Generic Programs): Do not say that

1433 Diagnose write errors in config.status instantiations.
1434 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)

1436 on write errors.
1437 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

1470 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
1471 gnulib.
1473 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1475 * lib/autoconf/status.m4: Fix a couple of comment typos.
1477 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1479 2007-11-13 Jim Meyering <meyering@redhat.com>
1481 Clean up the rule to create "expr".
1482 * tests/Makefile.am (expr): Don't redirect directly to target.
1483 Redirect just once, not for each echo statement.
1484 Use $@, not literal "expr".
1486 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1488 Don't worry about preprocessor when testing long long.
1489 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1490 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1491 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1492 These no longer check for preprocessor flaws.
1493 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1494 Do not check for preprocessor flaws.
1496 2007-11-13 Jim Meyering <meyering@redhat.com>
1498 Adapt dependencies, now that a version change doesn't modify configure.ac
1499 * GNUmakefile: Remove "make clean" kludge.
1500 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1501 configure.ac.
1502 Don't redirect directly to target.
1503 Use $@, not literal "version.m4".
1505 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1507 * doc/autoconf.texi (Making testsuite Scripts): Document
1508 ":;{" shorthand as in previous patch.
1510 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1512 * doc/autoconf.texi (Limitations of Builtins): Document problem
1513 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1514 for the workaround.
1515 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1516 Use ":;{" shorthand.
1517 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1519 2007-11-12 Jim Meyering <meyering@redhat.com>
1521 Add more non-srcdir build support.
1522 * GNUmakefile (dummy): Split a long line.
1523 Add -v option to autoreconf invocation.
1525 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1526 * GNUmakefile (dummy): Remove INSTALL.
1528 Remove racy commands to build scripts in bin/ and tests/.
1529 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1530 are guaranteed to be built, remove the rules that tried to build
1531 them. Before, with a parallel build, these rules could lead to
1532 two processes writing tests/wrapper.in concurrently.
1534 Build in man/ only *after* building in bin/ and tests/.
1535 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1536 in both bin/ and tests/.
1538 Accommodate non-srcdir build-from-checkout.
1539 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1540 Use git's --git-dir=$srcdir/.git option.
1541 Add quotes, in case tarball_version_file contains shell meta-characters.
1542 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1543 * configure.ac: Pass "." to git-version-gen.
1545 Avoid spurious test failures due to version skew.
1546 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1548 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1550 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1551 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1552 Remove conftest.dSYM directory.
1553 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1554 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1555 Remove `conftest.*' recursively.
1556 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
1557 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1558 Likewise.
1559 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
1560 * THANKS: Update.
1561 Report and analysis by Jeff Squyres and Peter O'Gorman.
1563 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
1565 Fix typos in variable names.
1566 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
1568 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
1570 Document that $((expression)) is not portable.
1571 * doc/autoconf.texi (Shell Substitutions): Here.
1573 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1575 Ignore configure --help* errors due to LINENO-impaired shells.
1576 * tests/torture.at (Configuring subdirectories, Deep Package):
1577 In the --help* tests in read-only trees, make `.' temporarily
1578 writable again for the `stderr' file, and ignore errors due to
1579 the attempt to write configure.lineno.
1580 Report by Patrick Welche.
1582 2007-11-10 Jim Meyering <meyering@redhat.com>
1584 Generate package.m4 in build-dir, not srcdir.
1585 * tests/Makefile.am (package.m4): Adjust target.
1586 Don't redirect directly to $@.
1587 (CLEANFILES): Add package.m4.
1588 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1589 in $(srcdir).
1590 When running $(AUTOTEST), search "." before searching $(srcdir).
1592 Avoid a race condition that would make parallel "distclean" fail.
1593 * tests/Makefile.am (distclean-generic): Replace the default,
1594 automake-provided rule with an identical one, but with an additional
1595 dependency on distclean-local. Simply adding the dependency would
1596 cause automake not to emit the rule at all.
1597 * BUGS: Building with -jN works, now.
1599 Distribute git-version-gen.
1600 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1601 since GNUmakefile is distributed, and requires it for dist* rules.
1603 Remove two more generated files from version control.
1604 * INSTALL: Remove generated file.
1605 * lib/autoscan/autoscan.list: Remove generated file.
1607 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1609 * GNUmakefile (PATH): Remove stray apostrophes; they become
1610 part of PATH, which isn't wanted here.
1612 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1614 New config files output variable `top_build_prefix'.
1615 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1616 `top_build_prefix'.
1617 * doc/autoconf.texi (Preset Output Variables): Document it.
1618 * NEWS: Update.
1619 Report by Bob Friesenhahn.
1621 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1622 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1623 function, to parametrize arithmetic with expr vs. the shell.
1624 Use it where possible.
1625 Suggestion by Benoit Sigoure.
1627 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1629 Adjust the documentation of autotest WRT atlocal.
1630 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1631 when using Automake, to write a rule to produce atlocal, since it's
1632 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1633 distributed, not atconfig.in.
1635 2007-11-04 Eric Blake <ebb9@byu.net>
1637 Update list information.
1638 * README: Mention new autoconf-commit list.
1639 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
1641 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1643 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
1645 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1647 * build-aux/.gitignore: Ignore mkinstalldirs.
1649 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1651 2007-11-03 Jim Meyering <meyering@redhat.com>
1653 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1654 * build-aux/git-version-gen: This syncs from coreutils.
1656 Adjust the build procedure so "make check" works reliably.
1657 * README-hacking: Include an extra step between "make" and
1658 "make check" to ensure that the latter passes.
1660 Use just-built tools, when possible.
1661 * GNUmakefile (PATH): Set and export here, ...
1662 (dummy): ... rather than here.
1664 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1665 and Andreas Schwab <schwab@suse.de>
1667 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
1668 exit status bug.
1670 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1672 * configure.ac (AC_PREREQ): Require version 2.60, for
1673 AC_PROG_SED, AC_PROG_GREP.
1675 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
1676 and Jim Meyering <meyering@redhat.com>
1677 and Andreas Schwab <schwab@suse.de>
1678 and Eric Blake <ebb9@byu.net>
1680 Document a bug in GNU Bash with compound commands and redirections.
1681 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
1682 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
1683 workaround.
1685 2007-11-03 Eric Blake <ebb9@byu.net>
1687 Support m4 1.4.5 in testsuite.
1688 * tests/torture.at (Define a newline): Exclude line numbers in
1689 error message.
1690 Reported by Ralf Wildenhues.
1692 2007-11-03 Jim Meyering <meyering@redhat.com>
1694 Remove automake-provided files from version control.
1695 * build-aux/elisp-comp: Remove file.
1696 * build-aux/install-sh: Remove file.
1697 * build-aux/missing: Remove file.
1698 * build-aux/mdate-sh: Remove file.
1699 * build-aux/.gitignore: New file.
1700 Suggestion from Ralf Wildenhues.
1702 2007-11-03 Eric Blake <ebb9@byu.net>
1704 Adjust version comparison to account for git snapshot numbers.
1705 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
1706 component separator.
1707 * doc/autoconf.texi (Number processing Macros)
1708 <m4_version_compare>: Document this change.
1709 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
1711 2007-10-30 Bruno Haible <bruno@clisp.org>
1713 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1714 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1715 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1716 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1717 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1718 Suggested by Paul Eggert.
1720 2007-10-28 Jim Meyering <meyering@redhat.com>
1722 * README-hacking: Autoconf, Automake, and Perl are required to build.
1723 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1725 2007-10-28 Jim Meyering <meyering@redhat.com>
1727 README-hacking: Recommend running autoreconf -vi.
1728 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1729 so that we use just-built tools when they're available.
1730 Suggestions from Ralf Wildenhues.
1732 2007-10-28 Jim Meyering <meyering@redhat.com>
1734 Make inter-release --version output more useful.
1736 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1737 which indicates that it is built using the 19th change set
1738 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1739 is a prefix of the commit SHA1.
1740 * build-aux/git-version-gen: New file.
1741 * configure.ac: Run it to set the version.
1742 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1743 * Makefile.am (dist-hook): Arrange so that .version appears only
1744 in distribution tarballs, never in a checked-out repository.
1745 * .gitignore: Add .version here, too. Just in case.
1746 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1747 not configure.ac, now that the version number changes automatically.
1749 Ensure that $(VERSION) is up to date for dist-related targets.
1750 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1751 git-version-gen doesn't match $(VERSION), but only for dist targets.
1753 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1755 Fix `Deep Package' failure with a configure script early in PATH
1756 * tests/torture.at (Deep Package): Add `.' early in PATH.

1775 documentation.
1777 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>
1779 * doc/make-stds.texi: Update from gnulib.
1781 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1782 and Eric Blake <ebb9@byu.net>
1784 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
1785 problem reported by Bruno Haible in
1786 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
1788 2007-10-22 Eric Blake <ebb9@byu.net>
1790 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
1791 preprocessor.
1793 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1795 Don't check for bug in HP-UX 11.00 cpp.
1796 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
1797 Use -1ull rather than -1u, since that causes problems with gnulib; see
1798 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
1800 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1816 escaping of backslash in here-documents.
1818 Fix `Deep Package' test failure on FreeBSD.
1819 * tests/torture.at (Deep Package): Do not add `.' to $PATH
1820 unnecessarily. Do not try running `/bin/sh configure' with a
1821 configure script to be found in $PATH, if the shell does not do
1822 this resolution. Fixes test failure on FreeBSD.
1824 Fix config header generation with AIX awk.
1825 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
1826 script, use helper array D_is_set, as `" 0"' does not evaluate

1829 2007-10-21 Eric Blake <ebb9@byu.net>
1831 * tests/autotest.at (Banners): Reinstate test, with typo

1864 * lib/autotest/general.m4 (BANNERS): New named diversion.
1865 (TESTS_END): Diversion no longer used.
1866 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
1867 shell function, which prints only as needed, using an associative
1868 array of banner text from a special diversion.
1869 <PARSE_ARGS_END>: No longer need awk to find banners.
1870 <TESTS>: Banners are no longer processed by main driver loop, so
1871 we no longer need case statement.
1872 (AT_BANNER): Rewrite to populate new diversion.
1873 (AT_SETUP): Each test invokes its own banner. No output is needed
1874 to the TESTS diversion.
1875 * doc/autoconf.texi (Writing Testsuites): Document slight
1876 semantics change.
1877 * tests/autotest.at (AT_BANNERS): Enhance test.

1904 understand --version won't try to behave interactively.

1923 (TEST_GROUPS): ...to this.
1925 Reject FreeBSD m4.

2900 2007-05-21 Paul Eggert <eggert@cs.ucla.edu>
2902 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp
2903 choice, since that's what we do with --enable-largefile etc.
2904 Redo indenting and assignments to simplify things a bit, and make
2905 the parens work with Emacs.
2907 * doc/autoconf.texi (Generic Compiler Characteristics): Fix typo
2908 in my previous change: AC_C_OPENMP -> AC_OPENMP. Reported by Bruno
2909 Haible.

2986 section titles and other comments; no code change.
2988 2007-05-01 Kevin Ryde <user42@zip.com.au>
2990 * doc/autoconf.texi (Particular Programs): Typo
2991 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
2993 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
2995 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
2996 'configure' will fail if the shell lacks proper support for shell
2997 functions. Suggested by RMS.
2999 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
3001 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
3002 about Solaris /bin/printf '%010000x' 123. Problem reported by
3003 Bruno Haible.
3005 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
3007 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
3008 for a.* when searching for executables, as this prevents users
3009 from having files like a.c. Problem reported by Ralf Wildenhues in:
3010 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
3011 This fixes a problem introduced on 2000-12-19.

3021 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
3022 AC_CHECK_TYPE, AC_CHECK_TYPES.
3023 * doc/autoconf.texi (Generic types): C types must be type-names
3024 (the C terminology), not type-ids (the C++ term). C++ types
3025 must not be anonymous.
3026 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
3027 for C++; this drops support for anonymous struct and union types,
3028 which were problematic anyway.
3029 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
3030 for C++.
3032 2007-04-12 Jim Meyering <jim@meyering.net>

3045 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
3046 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
3047 with objects too. Document the restrictions on its use.
3048 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3049 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3050 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3051 works but the latter doesn't, then it's a valid type.
3052 This lets people use function types and so forth.
3053 For C++ there doesn't seem to be a simple solution, so leave it alone.
3054 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3055 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3056 AC_CHECK_TYPE; that wasn't documented or necessary.
3058 2007-04-11 Stepan Kasal <kasal@ucw.cz>
3060 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

3103 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
3104 checks for unsigned long long int.
3106 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
3108 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
3109 nonstandard grep R.E. escape sequences.
3111 2007-03-17 Jim Meyering <jim@meyering.net>
3113 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3114 (Limitations of Usual Tools): Also list \< and \>, and mention that
3115 HP-UX's grep, like the one from Solaris, does not support that syntax.
3117 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3119 * doc/autoconf.texi (Specifying Names): `--host' does not
3120 change the build type.
3122 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3124 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN

3135 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
3136 universal binaries. Problem reported by Elias Pipping.
3138 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
3140 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.

3158 status of rm so we know when it failed.
3159 If cleaning of test dir failed before running the test, warn.
3160 Output the line separator in verbose mode before the warning
3161 to make clear the warning belongs to the following test.
3163 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>

3178 carriage return.
3179 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
3180 with traditional Awk and begin.
3181 * tests/torture.at (Limitations of Builtins): Document the problem

3186 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
3188 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
3189 input from /dev/null in awk test, so even Solaris /usr/bin/awk
3190 will not wait for input with a script containing only a BEGIN
3191 rule.
3193 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
3195 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version

3215 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
3217 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
3218 latest version.
3219 (Shell Substitutions): Note problems with @{var:=value} etc.
3220 Add a new section for problems with @{#var} etc. Problem noted

3224 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3226 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3227 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3228 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3229 substitution will still be done by the special code.
3230 Report by Jim Meyering.

3251 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3253 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3254 early on the reader side, drop stderr of the input to avoid
3255 `broken pipe' error output; this may happen even with shell
3256 builtin `echo' of some bash versions. Reports by Ian Macdonald
3257 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3259 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3261 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

3271 Fix some wording problems noted by Paolo Bonzini in:
3272 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3273 * doc/autoconf.texi (Signed Overflow Examples): Give more
3274 discussion about the allow_superuser_privileges example,
3275 and change it a bit to make things clearer.
3276 (Optimization and Wraparound): Clarify whether the compiler
3277 will generate an infinite loop for the example derived from
3278 Autoconf's mktime test.
3279 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3280 Also, clarify unsigned multiplication overflow.
3282 2007-01-04 Eric Blake <ebb9@byu.net>
3284 * bin/Makefile.am (RELEASE_YEAR): New macro.
3285 (edit): Use it to supply correct copyright year to scripts.
3286 * bin/autoconf.as (version): Use it.
3287 * bin/autoheader.in ($version): Likewise.
3288 * bin/autom4te.in ($version): Likewise.
3289 * bin/autoreconf.in ($version): Likewise.
3290 * bin/autoscan.in ($version): Likewise.
3291 * bin/autoupdate.in ($version): Likewise.
3292 * bin/ifnames.in ($version): Likewise.
3294 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3296 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3297 feedback. The most important changes document what happens when
3298 you convert an out-of-range value to a signed integer type, and
3299 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3300 a + b.
3302 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3303 rewrite, taking notions from the recent discussion on the gcc and
3304 autoconf mailing lists; please see
3305 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3306 and follow the many links.
3307 (Integer Overflow Basics, Signed Overflow Examples):
3308 (Optimization and Wraparound, Signed Overflow Advice):
3309 (Signed Integer Division): New sections.
3311 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3313 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3314 preprocessor macro arguments in traced name.
3315 * doc/autoconf.texi (Defining symbols): Document longstanding
3316 support for AC_DEFINE-ing macros with arguments, and document
3317 behavior when the same variable has multiple AC_DEFINEs.
3318 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3319 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3320 macros directly, giving much shorter and simpler code.
3322 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3324 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3325 space before "$ac_configure_args" to prevent a 'config.status
3326 --recheck' failure if ac_configure_args doesn't contain a leading
3327 space. This works around a problem with the XEmacs configure.ac,
3328 which uses the (undocumented) ac_configure_args variable
3329 inconsistently with Autoconf.
3331 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3333 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3334 Include <limits.h>, and use its INT_MAX to rewrite the
3335 j loop so that it does not overflow 'int'. Problem reported by
3336 Ralf Wildenhues in
3337 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3338 Play it safe by shifting left by 1 rather than multiplying by 2,
3339 as GCC is less likely to optimize this away when the value
3340 is signed (when it assumes overflow leads to undefined behavior).
3341 Also, don't assume time_t uses two's complement.
3343 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3345 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3346 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3347 dumps core on it. Report by Tim Rice.
3349 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3351 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3352 --disable-option-checking to --help output even when
3353 AC_PRESERVE_HELP_ORDER is not used.
3354 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3355 --with argument, rather than argument with [-.] replaced by
3356 underscores.
3357 * NEWS: Fix typo in previous change; the news was in the
3358 wrong section.
3360 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3362 * NEWS: Warnings are now generated by default for unknown
3363 --enable-* and --with-* options.
3364 * doc/autoconf.texi (Option Checking): Renamed from
3365 (Configure Option Checking). Tighten up the wording a bit.
3366 (External Software, Package Options): Cross-reference to Option
3367 Checking, and use this to shorten our section.
3368 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3369 "$x" to test "x$foo" != x.
3370 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3371 Don't warn if $enable_option_checking is "no".
3372 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3373 ac_unrecognized_opts to the empty string.
3374 Don't echo the unrecognized opts, as this might mishandle
3375 backslashes or leading -.
3376 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3377 usage next to the other --disable-FEATURE options in the
3378 help string.
3380 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3382 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3383 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3384 Print warning for unrecognized --with and --enable options
3385 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3386 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3387 Disable option checking when subdirs are configured.
3388 (AC_OUTPUT): If warnings are enabled, print warning about
3389 unrecognized --with and --enable options at the end of
3390 the configure output (as well as at the beginning).
3391 * doc/autoconf.texi (Option Checking): New node.
3392 Document new option warning functionality.
3394 2006-12-16 Eric Blake <ebb9@byu.net>
3396 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3397 * NEWS: Start news for current version.
3399 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3401 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3402 Define HAVE_GETMNTENT to 1, not to the empty string.
3403 Problem originally reported by Jochen Friedrich in
3404 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3406 This change prompted by a problem report by Andrey Simonenko in
3407 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3408 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3409 object-like macros only, in the traditional portable character
3410 set.
3411 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3412 Warn about attempts to define things that are not identifiers.
3413 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3414 awful hack that AC_DEFINEd macro names containing parentheses.
3416 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3418 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3419 too drastic, even if Texinfo in theory requires it for info mode.
3421 (config.status Invocation): Renamed back from Recreating a
3422 Configuration).
3423 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3424 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3426 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3428 * NEWS: Version 2.61a.
3430 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3431 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3433 * NEWS: Document changes with echo and printf, and the lack
3434 of limits on the total size of multi-line values of substituted
3435 variables, and the AC_FUNC_FSEEKO fix.
3437 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3439 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3440 Writing configure.ac.
3441 (Autoconf Input Layout): Renamed from configure.ac Layout.
3442 (Recreating a Configuration): Renamed from config.status Invocation.
3443 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3444 (acconfig Header): Renamed from acconfig.h.
3445 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3446 (Writing Testsuites): Renamed from Writing testsuite.at.
3447 (Autom4te Cache): Renamed from autom4te.cache.
3449 * BUGS: Remove mention of VPATH problem, since it's now documented
3450 not to be a bug in the Autoconf build procedure itself, but rather
3451 a problem with the proprietary `make' programs.
3453 * doc/autoconf.texi (Build Directories): Add a cross reference
3454 to VPATH and Make.
3456 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3457 * doc/standards.texi: Sync from gnulib.
3459 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3460 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3461 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3462 generated automatically.
3464 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3466 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3467 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3468 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3470 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3472 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3473 `CEOF$ac_eof' special marker, the awk script cannot contain a
3474 line matching `^CEOF', so this is not needed any more.
3475 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3476 special marker in the test.
3478 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3480 * tests/tools.at (autom4te preselections): Use `find -newer';
3481 remove one of the sleeps.
3483 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3484 more readable, using ...
3485 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3487 * doc/autoconf.texi (autoheader Invocation): Do not double-
3488 quote the parameter of `AH_BOTTOM' in the example.
3490 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3492 * doc/autoconf.texi (Configuration Headers): Remove the
3493 example with multiple input files.
3494 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3495 multiple input files.
3497 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3499 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3500 creating the awk substitution script, handle one input line at a
3501 time, so that the maximum length of a substituted (multi-line)
3502 value is not limited by the size of the sed pattern space.
3503 The trade-off is a slightly repetitive sed script.
3504 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3505 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3506 * tests/torture.at (Substitute a 2000-byte string): Increase the
3507 test with several long lines, they should not be caught by sed
3508 limits any more.
3510 * tests/tools.at (autom4te preselections): New test, to flag
3511 entries missing from autom4te.cfg.
3512 Report by David Byron <dbyron@hheld.com>.
3514 * tests/torture.at (Substitute a 2000-byte string): Actually use
3515 AC_PROG_AWK, so the last change works as intended.
3516 (Substitute and define special characters): Likewise.
3517 (Substitute a newline): Likewise.
3519 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3520 instead of `awk' consistently.
3521 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3522 * tests/torture.at (Torturing config.status): Test both the
3523 result of AC_PROG_AWK and plain awk.
3524 (Substitute a 2000-byte string): Likewise.
3525 (Substitute and define special characters): Likewise.
3526 (Substitute a newline): Likewise.
3528 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3530 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3531 can be assigned to a function pointer. Problem reported by
3532 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3533 part of a patch by Ralf Wildenhues in that same bug report.
3535 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3537 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3538 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3540 2006-12-01 Eric Blake <ebb9@byu.net>
3542 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3543 cross-compiling from cygwin to mingw.
3544 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3545 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3546 to lib/autoconf/c.m4.
3548 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3550 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3551 string for more reliable failure. Wrap the entire test that
3552 causes the broken Solaris printf to dump core, in a subshell,
3553 so the segmentation fault message is reliably suppressed.
3554 Fix shell expansion errors by using /usr/ucb/echo always;
3555 avoid an error on systems without it by another subshell.
3556 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3557 subshell-$as_echo to `as_echo', for better error message.
3559 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3561 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3562 `BASH_SOURCE' contain a newline, set them to empty, as they may
3563 not be unset.
3565 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3567 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3568 years and is too hard to maintain now. The last straw was
3569 reported by Jerker Baeck in
3570 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3571 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3572 * doc/autoconf.texi (Particular Functions): Move
3573 AC_FUNC_SETVBUF_REVERSED from here...
3574 (Obsolete Macros): ... to here. Say that it does nothing now.
3575 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3576 Turn into (almost) a no-op.
3578 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3579 (AC_C_VOLATILE):
3580 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3581 These macros are obsolescent and new applications shouldn't need them.
3582 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3583 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3584 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3585 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3586 (AC_FUNC_VPRINTF): Likewise.
3587 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3588 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3589 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3591 * doc/autoconf.texi (Setting Output Variables): Mention that
3592 @VAR1@VAR2 has unspecified behavior. Problem reported by
3593 Ralf Wildenhues.
3594 * NEWS: Mention this.
3596 * Makefile.am: Put only a single '#' into the copyright notice,
3597 so that it's also present in the output file. Standardize wording
3598 in makefile copyright notices to match GNU coding standards.
3599 * bin/Makefile.am: Likewise.
3600 * doc/Makefile.am: Likewise.
3601 * lib/Makefile.am: Likewise.
3602 * lib/freeze.mk: Likewise.
3603 * lib/autoconf/Makefile.am: Likewise.
3604 * lib/autoscan/Makefile.am: Likewise.
3605 * lib/autotest/Makefile.am: Likewise.
3606 * lib/m4sugar/Makefile.am: Likewise.
3607 * man/Makefile.am: Likewise.
3608 * tests/Makefile.am: Likewise.
3609 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
3610 one-line file.
3612 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3614 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3615 in the sed script that mangles the awk script: delete up to the
3616 first exclamation mark only.
3617 * tests/torture.at (Substitute and define special characters):
3618 Test '!' too.
3620 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3622 Rewrite config files generation: avoid quadratic growth in
3623 the number of substituted variables by using awk instead of sed
3624 for the bulk of the substitutions.
3625 * NEWS: Mention this.
3626 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3627 forbidden in the output (and thus input) file.
3628 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3629 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3630 generate just one large awk script for substitutions,
3631 eliminating much of the earlier complexity, while adding some
3632 new complexity. Only expand the substitution templates at
3633 configure time, for smaller configure script size. If
3634 _AC_SUBST_FILES are used, test 'awk' for working getline support
3635 at config.status time. If absent, interpolate through the
3636 shell. The awk script was written with much help
3637 from Paolo Bonzini and Paul Eggert.
3638 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3639 (_AC_SED_FRAG_NUM): Likewise.
3640 (_AC_SUBST_CMDS): Renamed from...
3641 (_AC_SED_CMDS): ...this.
3642 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3643 * tests/torture.at (Substitute a 2000-byte string): Also
3644 substitute a line with 1000 words, and a variable with several
3645 long lines.
3646 (Substitute and define special characters): Test awk special
3647 characters, and put substitution input strings `@foo@' in the
3648 output, to test that no recursion happens; test several other
3649 combinations from Paolo Bonzini.
3651 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3653 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3654 that replaced echo with AS_ECHO where this wasn't necessary.
3655 Problem reportd by Ralf Wildenhues.
3656 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3657 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3658 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3660 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3662 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3664 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3666 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3667 that traditional Awk lacks 3-arg "split". It has it.
3668 Mention that FS must be a single character, and a few other
3669 99-byte limits of traditional Awk.
3670 Mention that if (i in a) doesn't work with traditional Awk.
3672 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3674 * tests/autotest.at (BSx641-newline in command):
3675 (BS-BS-newline in command, BSx640-newline in command):
3676 (Newline-CODE-BS-newline in command):
3677 (Single-quote-BS-newline in command):
3678 (Single-quote-newline-BS-newline in command):
3679 Use printf '%s\n' instead of echo, for portability to hosts
3680 where echo interprets backslashes. This will break on hosts
3681 that lack printf, but for now let's assume all such hosts
3682 are dead (if not, we should get reports of test failures).
3684 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3686 'echo' has some portability problems, when given a first argument
3687 with a leading '-', or when given any argument containing '\'.
3688 Avoid using 'echo' in these cases.
3689 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
3690 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
3691 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3692 * lib/autotest/general.m4 (AT_INIT): Likewise.
3693 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
3694 argument might be unportable.
3695 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
3696 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
3697 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
3698 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
3699 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
3700 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
3701 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
3702 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
3703 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.

3709 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
3710 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
3711 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
3712 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
3713 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3714 * bin/autoconf.as: Redo verbose flag implementation, as the old
3715 scheme wouldn't work with AS_ECHO.
3716 * lib/autotest/general.m4 (AT_INIT): Likewise.
3717 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3718 Don't use ECHO_T, since ECHO_N is now reliable.
3719 * lib/autotest/general.m4 (AT_INIT): Likewise.
3720 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3721 rather than using a here-document to put the script into a file.
3722 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3723 use AS_ECHO.
3724 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3725 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3726 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3727 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3728 * lib/autotest/general.m4 (AT_SETUP): Likewise.
3729 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
3730 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3731 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3732 operand, as AS_ECHO requires. Avoid double file name expansion.
3733 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3734 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3735 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3736 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3737 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3738 Double-quote strings that would otherwise contain M4 comments.
3739 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3741 * configure.ac (AC_INIT): Bump to 2.61a.
3742 * NEWS: Likewise.
3744 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3746 Version 2.61.
3748 * configure.ac (AC_INIT): Bump to 2.61.
3749 * NEWS: Likewise.
3751 * tests/autotest.at (Macro with backslash in a test title):
3752 Comment out for now, as this tests neither fails nor passes
3753 reliably. Problem reported by Ralf Wildenhues.
3755 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3757 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
3758 in previous change, which caused test failures.
3760 2006-11-16 Stepan Kasal <kasal@ucw.cz>
3762 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
3763 code for --enable, --disable, --with, and --without to...
3764 (_AC_INIT_PARSE_ENABLE): ... a new macro.
3765 * doc/autoconf.texi (Package Options):
3766 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
3768 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3770 Import these changes from config via gnulib:
3772 2006-11-15 Ben Elliston <bje@gnu.org>
3774 From Josselin Mouette <joss@debian.org>:
3775 * build-aux/config.guess (SX-8:SUPER-UX:*:*): New.
3777 2006-11-08 Ben Elliston <bje@gnu.org>
3779 * build-aux/config.guess (authenticamd:Interix*:[3456]*): Another AMD64.

3845 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set

3847 Imported from a similar patch to gnulib by Bruno Haible.
3849 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3851 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

3875 argument. Extend to check titles printed by ./micro-suite and
3876 ./micro-suite -l and the title in micro-suite.log.
3877 (Backquote in a test title,
3878 Single-quote in a test title,
3879 Double-quote in a test title): Don't expect failure anymore.
3880 (Backslash in a test title): Put a non-whitespace character after the
3881 backslash so that Bourne shells might actually see it as an escape
3882 sequence.
3883 (Brackets in a test title,
3884 Pound in a test title,
3885 Comma in a test title,
3886 Quoted Macro in a test title,

3892 * tests/torture.at (#define header templates): M4-quote this title in
3893 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3894 The visible effect was a stray [] in the testsuite output.
3896 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3898 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3899 `trap ... 0' inside a function, for AIX sh.
3901 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3903 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3904 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3905 5363) simply issues a warning when dividing by zero at compile
3906 time. Problem reported by Elias Pipping.
3908 2006-10-26 Eric Blake <ebb9@byu.net>
3910 * THANKS: Update.
3911 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3912 show effect on macros that expand with commas.
3913 Reported by Joel E. Denny.
3915 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
3916 Also work with M4 1.4.8.

3939 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3940 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3941 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3942 reported by Nelson H. F. Beebe for Coreutils 6.4.
3944 * tests/tools.at (autoconf --trace: user macros): Remove test
3945 for tracing multiline macros, since m4 1.4.7a uses a different
3946 way to number lines. Problem reported by Ralf Wildenhues.
3948 2006-10-24 Stepan Kasal <kasal@ucw.cz>
3950 * bin/autom4te.in (handle_m4): Do not redirect stdin to
3951 /dev/null since the heuristics for interactive behaviour was
3952 fixed in CVS m4.
3954 * bin/autom4te.in: With --force, always refresh the output
3955 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

3976 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
3977 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
3979 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3981 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.

4008 looking for special shell characters.
4009 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4010 macro defined by AS_VAR_PUSHDEF before passing it as a
4011 parameter.
4012 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):

4022 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4024 (Imported from Automake.)
4025 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4026 which incorrectly sets the mode of an existing destination
4027 directory. In some cases the unpatched install-sh could do the
4028 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4029 system. We hope this is rare in practice, but it's clearly worth
4030 fixing. Problem reported by Alex Unleashed in
4031 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4032 Also, don't bother to check for -m bugs unless we're using -m;
4033 suggested by Stepan Kasal.
4035 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>

4041 is enabled by default with gnu and gnits strictness.
4042 Report from Bruno Haible.
4044 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
4045 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
4046 gnu and gnits modes.
4048 Import this change from Config:
4050 2006-09-20 Ben Elliston <bje@gnu.org>

4053 Import this change from Gnulib:
4055 2006-09-16 Karl Berry <karl@gnu.org>
4056 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4057 to avoid sectioning errors.

4061 2006-10-04 Karl Berry <karl@gnu.org>
4062 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

4066 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
4067 (\code): must use new \...Char values, since now ` is active.
4069 2006-08-26 Karl Berry <karl@gnu.org>
4070 * build-aux/texinfo.tex (\textdegree): New command.
4072 2006-08-12 Karl Berry <karl@gnu.org>

4077 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4079 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4081 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4082 added to the template can get mangled.
4084 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4086 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4087 include the default headers, and redefine obstack_chunk_alloc
4088 and obstack_chunk_free. Fixes false failure with glibc.
4090 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4092 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
4093 for backward compatibility with Libtool 1.5.22. Problem reported
4094 by Ralf Wildenhues.
4096 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4098 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
4099 AC_PROG_CC.

4102 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>

4107 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4109 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4110 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4111 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4112 Use a better substitute, by inspecting the output of "ls"
4113 rather than just using ":".
4114 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4115 rather than AS_EXECUTABLE_P, since we needn't worry about
4116 non-regular files here.
4118 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4119 due to configuration hassles with this. See Tonya Underwood's report
4120 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4121 * doc/autoconf.texi (Special Shell Variables): Likewise.

4131 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4132 initialization which is not inherited through the environment
4133 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4134 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4136 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4138 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4139 problems with mkdir -p -m.
4141 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4143 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4144 comment about ac_cpp_err; it was incorrect, and anyway
4145 ac_cpp_err is being removed below.
4146 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4147 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4148 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4149 nobody uses it.
4150 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4151 with werror_flag and conftest.err and so forth. This is more
4152 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4153 and anyway the user shouldn't normally want to see this gorp logged.
4154 Problem reported by Ralf Wildenhues.
4155 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4156 empty, not 'no', since the rest of the code uses 'test -z'.
4158 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4160 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4161 Use a single call to AC_DO_TOKENS rather than multiple, for
4162 efficiency.
4163 (_AC_LINK_IFELSE): Test that resulting file is executable.
4164 Problem reported by mwoehlke in
4165 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4167 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4168 than creating a file to use with test -x; this is much faster.
4170 2006-10-02 Bruno Haible <bruno@clisp.org>
4172 * lib/autom4te.in (Automake-preselections): Add
4173 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4175 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4177 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4178 standard error, `experr' should be used, not `expout'.
4180 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4182 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4183 fseeko testing program twice; just use the earlier result.
4184 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4185 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4186 still doesn't let the program compile.
4187 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4188 failed.
4190 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4191 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4192 include it, without including anything else.
4193 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4194 expressions.
4195 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4197 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4199 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4200 `error.h', and include it, for a `error_at_line' prototype.
4201 Use a nonempty format string in the link test.
4202 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4203 for a declaration of wait3.

4208 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4209 can apply to constants too, and that it checks for macro defns.

4211 and simply cast the identifier to void. This handles structure
4212 values. Problem reported by Ralf Wildenhues.

4302 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check

4312 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
4313 works with GNU M4 1.4.3 again; make the normalized form
4314 match the current m4 message; fix the description.

4323 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
4324 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
4325 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
4326 assume C89.

4348 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
4349 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
4350 accept files with extension `.f'. For consistency, also prefer
4351 xlf over f77.
4352 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug

4424 deal with LEXLIB.
4425 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
4426 didn't work if some values were cached but not others. Test for
4427 broken lex libraries like native ia64-hp-hpux11.22; see
4428 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4429 work around the problem by preferring an empty LEXLIB to -lfl or
4430 -ll. Let the user set LEXLIB='' to indicate no library needed.
4432 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
4433 * README: Likewise.
4434 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

4662 reported by Keith Marshall. Also, don't bother with builddir2,
4663 since it shouldn't be needed any more.
4665 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

4691 that long long int is 32 bits wide with some nonstandard compilers.
4692 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
4694 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4696 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4697 to a nonexistent file, so that we don't have to worry about
4698 a local site configuration that doesn't use /usr/local.
4699 Problem reported by Keith Marshall in
4700 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4702 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4704 * doc/autoconf.texi: Be more consistent about using @acronym with
4705 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4706 quite right (it talked about "OSF/Tru64", even though the
4707 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4708 and it even mentioned "OSF 4"!) and at this point there's little
4709 reason to talk about OSF any more, since it died in 1994.
4710 (Specific Compiler Characteristics): Simplify example of
4711 negative-size array.
4712 (File Descriptors): Reorder to make the text flow better.
4713 Remove joke about "appreciate the various levels"; I didn't get it.
4714 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4715 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4716 (File Descriptors, Limitations of Usual Tools):
4717 Tone down the advice against renaming or removing open files.
4718 (Limitations of Usual Tools): Add a new section, on 'rm'.
4720 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4722 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4723 -lXt in LIBS, idea from Karsten Hopp; this was due since
4724 this change:
4726 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4727 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4728 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4729 (which belong to Xt, not X itself). See Debian bug 327655.
4731 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4733 * configure.ac (AC_INIT): Bump to 2.60a.
4734 * NEWS: Update.
4736 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4738 Version 2.60.
4740 * configure.ac, NEWS: Update.
4742 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4744 * config/texinfo.tex: Sync from upstream.
4746 * bin/autom4te.in (handle_traces): Transform the `@S|@'
4747 quadrigraph correctly in traces.
4749 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
4750 Fix typos.
4752 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
4753 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4754 not defined.
4755 * doc/autoconf.texi (Changed Directory Variables): New node,
4756 to document the whole `datarootdir' business a bit better.
4757 * NEWS: Update.
4758 * tests/torture.at (datarootdir workaround): Extend test.
4759 Prompted by report by Alexandre Julliard.
4761 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4763 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4764 when using default mode of IBM C 6 for AIX. Problem and two-line
4765 fix reported by Larry Jones.
4767 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4769 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4770 about literal '${datarootdir}' if a definition is found in the
4771 output file.
4773 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4775 * NEWS: Use "M4" rather than "m4" when appropriate.
4776 Problem reported by Eric Blake.
4777 * doc/autoconf.texi: Likewise.
4778 Use @acronym around BSD, GCC, and GNU when appropriate.
4779 (Why GNU M4): Renamed from "Why GNU m4".
4780 (Redefined M4 Macros): Mention that Posix
4781 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4782 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4783 to int.
4785 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4787 * bin/autom4te.in (handle_output): Do not forbid the empty
4788 pattern.
4789 * tests/tools.at (autoconf: the empty token): New test.
4791 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4793 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4794 calls, so that we do not care whether they are LIFO or FIFO;
4795 in the m4_wrap, do not check which diversion is the topmost
4796 one, just check that the stack is balanced at the end.
4797 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4798 base diversion forever--pop the previous diversion before
4799 opening the new one; consequently, remove the m4_wrap call.
4800 * lib/autotest/general.m4 (AT_INIT): Likewise.
4801 * tests/m4sugar.at: Do not use
4802 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
4804 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4805 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4807 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4808 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4809 Rework example of m4wrap token-pasting trouble so that it doesn't
4810 care whether it's LIFO or FIFO.
4811 Fix some "contrary to"s that are awkward in English.
4813 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4815 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4816 to `yes' instead of `int$1_t' if the type is found, for more
4817 consistent configure output (where $1 is the number of bits).
4818 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4819 Suggested by Bruno Haible.
4821 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4822 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4823 with system headers. Report by Bruno Haible.
4825 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4827 * config/config.guess, config/config.sub: Sync from upstream.
4829 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4830 in order to avoid picking up an older installed frozen m4sh.m4f.
4831 Besides an outdated shell startup, this could have been created
4832 by an earlier M4 version with incompatible frozen file format.
4834 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4836 * README: Recommend m4 1.4.4 instead of 1.4.3..
4837 * doc/autoconf.texi: Likewise.
4838 (Special Chars in Names): Say that $(.FOO) is portable, as
4839 suggested by Stepan Kasal.
4840 (Installation Directory Variables, Build Directories):
4841 (Automatic Remaking, Subdirectories, Fortran Compiler):
4842 (Making testsuite Scripts, Defining Directories):
4843 Quote variable usages better.
4844 (Making testsuite Scripts): Add clean-local rule to makefile
4845 snippet, by Eric Blake.
4846 (Installation Directory Variables): Fix table item font.
4847 Reword slightly to clarify. Generalize advice about
4848 not using special characters to include all file-related
4849 vars, not just VPATH.
4850 (Special Chars in Variables): Warn about special characters in
4851 $(srcdir) too.
4852 (Assignments): Clarify default-value example as suggested by
4853 Ralf Wildenhues in
4854 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4855 (Special Shell Variables): Note leading ./ or ../, as suggested
4856 by Eric Blake.
4857 (Limitations of Builtins): Under cd, warn about CDPATH.
4858 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4859 Ralf Wildenhues.
4861 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4863 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4864 `@var', for texi2html.
4865 (Systemology): Some more word wrapping, for DVI output.
4866 (autom4te Invocation): The short option for `--melt' is `-M',
4867 not `-m'.
4869 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4871 * doc/autoconf.texi: More formatting and English tweaks,
4872 many suggested by Ralf Wildenhues.
4873 Reword to avoid "@code{...}'s" and the like, since it's ugly
4874 with Emacs info mode. discontents -> woes.
4875 Put a few "will"s back. time stamp -> timestamp.
4876 side-effect -> side effect.
4878 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4880 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4881 Warn about $@ not persisting. Problem reported by Julien Danjou in
4882 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4883 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4884 Mention other special chars, too.
4886 2006-06-14 Eric Blake <ebb9@byu.net>
4888 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4890 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4892 * doc/autoconf.texi: Some systematic minor improvements, as
4893 follows. Use "makefile" when talking about makefiles
4894 generally (which might be named "makefile" or "Makefile" or even
4895 "foo.mk"), "Makefile" when talking about a specific makefile
4896 called "Makefile". This unclutters the text from weird quotes
4897 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4898 values" rather than "@var{foo}s" and similar constructs containing
4899 "}s". Use "Make rules" rather than "Makefile rules". Minor
4900 English-language improvements. Change the prefix "sub-" to "sub"
4901 and "re-" to "re".
4902 Put blank lines around examples more consistently.
4903 Avoid "rather" and "very" as intensifiers.
4904 Avoid "will" as an auxiliary.
4905 (Limitations of Make): Split this node into....
4906 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4907 (Leading _ in Macro Names, Backslash-Newline-Newline):
4908 (Backslash-Newline Comments, Long Lines in Makefiles):
4909 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4910 (obj/ and Make, make -k Status, VPATH and Make):
4911 (VPATH and Double-colon, $< in Explicit Rules):
4912 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4913 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4914 New nodes, resulting from splitup of Limitations of Make.
4915 All cross-references changed. Raise the top node from
4916 a section to a chapter, and all subnodes accordingly.
4917 Redo the introductory wording to match the new organization.
4918 (Installation Directory Variables): Use an example that is
4919 closer to what Autoconf actually does. Mention that VPATH's
4920 value should not contain metacharacters or white space.
4921 (Fortran Compiler): Fix a VPATH bug in an example.
4922 (Leading _ in Macro Names): Mention that this problem is no longer
4923 of practical concern.
4924 (VPATH and Make): Reword the advice to make it clearer
4925 that Autoconf and Automake support VPATH in non-GNU make, but
4926 many packages have bugs in this area.
4927 ($< in Explicit Rules): Refer to Build Directories rather
4928 than using a (non-VPATH-safe) example.
4929 (Automatic Rule Rewriting): Mention the sort of disaster that
4930 can ensue with Solaris-style rule rewriting with VPATH.
4932 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4934 * doc/install.texi (Compilers and Options): Weaken the
4935 suggestion to use GNU make for VPATH builds.
4937 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4938 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4940 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4941 in regular expression.
4943 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4945 * doc/autoconf.texi (Installation Directory Variables):
4946 Drop extra @samp from `@table @samp' item.
4947 (Limitations of Usual Tools): Comment fix.
4948 Do not nest @samp just to point to other table items.
4949 (Writing testsuite.at) <AT_CHECK>: The second argument to
4950 `@dvar' is already @samp'ed.
4951 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4952 do not use @var in the second argument.
4954 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4956 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4957 $as_shell.exe too. Problem reported by Andreas Buening in
4958 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4960 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4962 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4963 `unused variable' compiler warning, for `-Wall -Werror'.
4964 Reported by Jaap Haitsma in
4965 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4967 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4969 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4970 case the compiler dumps core. Problem reported for
4971 OpenServer 5.0.7 by Tim Rice in
4972 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
4973 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4974 Likewise.
4976 2006-06-06 Tim Rice <tim@multitalents.net>.
4978 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4979 "ERROR" only shows up in "make check" output if there is an
4980 error.
4982 2006-06-06 Eric Blake <ebb9@byu.net>
4984 * tests/tools.at (automatically allowed tokens): Fix typo.
4986 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4988 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
4990 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
4991 typically overflows on x86 CPUs, even though the C standard
4992 requires otherwise.
4994 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4996 * configure.ac (AC_INIT): Bump to 2.59e.
4997 * NEWS: Update.
4999 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5001 Version 2.59d.
5003 * config/texinfo.tex: Sync from upstream.
5005 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5006 seen, invoke libtoolize with `--ltdl' argument.
5007 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5008 * NEWS: Update.
5009 Suggested by Eric Blake.
5011 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5013 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5014 reported by Ralf Wildenhues.
5015 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
5017 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5019 * THANKS: Update.
5021 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5023 * doc/autoconf.texi: Modernize some of the references to Solaris.
5025 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5027 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5028 message issued by AC_REQUIRE.
5029 * tests/m4sugar.at: Check m4_require's error message.
5030 * tests/base.at: Check AC_REQUIRE's error message.
5031 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5032 to...
5033 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5034 AT_CHECK_M4.
5035 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5036 `expout' as the last parameter.
5037 * tests/tools.at: Adapt to the above change.
5039 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5041 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5042 information about race-free implementations of mkdir.
5044 2006-06-04 Eric Blake <ebb9@byu.net>
5046 * bin/autoreconf.in (help): Document M4 environment variable.
5047 * bin/autoconf.as (Usage): Likewise.
5048 * bin/autom4te.in (help): Likewise.
5049 * doc/autoconf.texi (autom4te Invocation): Likewise.
5051 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5053 * NEWS: GNU make now recommended for VPATH builds.
5054 Mention that some macros are now documented to be obsolescent.
5055 * doc/autoconf.texi:
5056 Prefer "current" to "modern" to describe
5057 currently-used (albeit perhaps old-fashioned) hosts.
5058 Mention which ancient features no longer need to be worried about.
5059 setgid -> set-group-ID
5060 setuid -> set-user-ID (these are the Posix terms)
5061 Fix some misuses of "only".
5062 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5063 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5064 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5065 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
5066 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
5067 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
5068 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
5069 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
5070 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
5071 Mention that these macros are obsolescent.
5072 (Installation Directory Variables): shall -> should
5073 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5074 Mention that it's now safe to use 3 and 4.
5075 (Limitations of Usual Tools): cp -r is now specified by Posix.
5076 Omit longwinded and obsolescent discussion of cp -f.
5077 Modernize discussion of expr, ls.
5078 (Limitations of Make): Modernize discussion of VPATH builds.
5079 Mention $? as a workaround in some cases.
5080 * doc/install.texi (Basic Installation):
5081 Mention "./configure; make; make install" first. Be more
5082 specific about why this file is generic. Remove unnecessary
5083 parens. Remove misleading "only". Remove obsolete advice
5084 about csh. Don't say "configure" takes awhile; say it
5085 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5086 and CC=c99 rather than CC=c89, as these are blessed by current
5087 Posix. Recommend GNU make if doing a VPATH build.
5089 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5091 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5092 examples involving shell prompts.
5094 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5095 and Paul Eggert <eggert@cs.ucla.edu>
5097 * doc/autoconf.texi (Here-Documents): Add details about the
5098 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5099 use "here-documents" instead of "here documents".
5101 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5103 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5105 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5107 * doc/autoconf.texi (File System Conventions): Warn about ":"
5108 anywhere in directory names.
5110 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5112 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5113 about quoting the case statement, just in case.
5114 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5115 was fixed in ksh93g; reported by Ralf Wildenhues.
5117 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5119 * doc/autoconf.texi (System Services): Do not document
5120 overriding EXEEXT via ac_cv_exeext=ext.
5121 (Particular Programs) <AC_PROG_MKDIR_P>:
5122 Document that ${MKDIR_P} understands --.
5123 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5124 comment.
5126 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5128 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5129 argument with leading hyphen. Problem reported by Paul Eggert.
5131 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5133 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5134 about quoting ac_try: quote all of it, if any of it seems suspicious.
5135 This means we don't have to worry about ${ or sed any more.
5136 Also, double-quote the case statement, to work around misuses via
5137 underquoting as reported by Ralf Wildenhues in
5138 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5139 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5140 undocumented and dangerous macro.
5141 Problem reported by Ralf Wildenhues in
5142 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5144 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5146 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5147 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.

5150 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5152 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5153 since evidently some packages rely on the old, broken behavior.
5154 Problem reported by Ralf Wildenhues in
5155 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5156 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5157 pre-2006-05-26 definitions, but leave in the comments that
5158 these macros are dangerous and should not be used.
5159 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5160 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5161 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5162 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5163 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5165 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5167 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5168 the use of 'tr', since this is our only use of 'tr'.
5170 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5171 and Paul Eggert <eggert@cs.ucla.edu>
5173 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5174 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5176 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5178 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5179 the output file in the `${datarootdir}' test.
5181 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5182 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5184 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5185 mention of `datarootdir' in the input file(s), but literal
5186 `${datarootdir}' in the output file, and we haven't warned yet,
5187 then warn as well: the user may have (erroneously) used
5188 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5189 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5190 * tests/torture.at (datarootdir workaround): Extend this test.
5191 * NEWS: Update.
5193 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5194 and Paul Eggert <eggert@cs.ucla.edu>
5196 * doc/autoconf.texi (autoheader Invocation): The first argument to
5197 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5198 alternatives and clear up the language a bit.
5200 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5202 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5203 ac_config_guess, ac_config_sub, ac_configure.
5204 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5205 Fix typo that prevented an unnecessary space from being removed.
5206 Problems reported by Ralf Wildenhues in:
5207 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5209 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5211 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5212 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5213 Don't use the term "thread-safe" to talk about mkdir race
5214 conditions, since the problem is more a process than a thread
5215 issue. Problem reported by Stepan Kasal in:
5216 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5217 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5218 the test for 'install' more closely. Look at MKDIR_P first.
5219 Look in the PATH, and at /opt/sfw/bin.
5220 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5221 Don't bother to try mkdir -p, since we already check mkdir --version;
5222 just look at the version number. (There's no easy way to check
5223 for race-free implementations.)
5224 * tests/tools.at (autoconf: subdirectories): Adjust to above
5225 changes, since MKDIR_P now might end in "/mkdir -p".
5227 * doc/autoconf.texi (autoheader Invocation): Mention that the
5228 first arg of AC_DEFINE_UNQUOTED must be a literal.
5229 Problem reported by Ben Pfaff in
5230 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5232 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5233 * doc/autoconf.texi (Special Chars in Variables): New section.
5234 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5235 (Installation Directory Variables): Quote $(datadir) better.
5236 (Limitations of Builtins): Describe some of eval's trickiness.
5238 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5239 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5240 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5241 in front of every arg, not just trailing args. Quote apostrophes.
5242 (_AC_EVAL_ECHO): New macro.
5243 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5244 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5245 removed.
5246 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5247 exposed by quoting of eval argument. Put the command on line line
5248 so it logs better.
5249 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5250 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5251 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5252 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5253 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5254 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5255 Use eval more safely.
5256 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5257 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5258 to be replaced.
5259 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5260 lines, exposed by quoting of eval argument.
5262 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5263 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5265 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5266 initialization of `ac_cv_exeext', do not override it if it was
5267 already set, unless it was set to `no', for compatibility with
5268 Autoconf-2.13, and comment this.
5269 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5270 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5271 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5272 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5273 Document that this test may be overridden by setting
5274 `ac_cv_exeext'.
5276 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5278 Revert these two patches:
5280 2006-04-06 Eric Blake <ebb9@byu.net>
5281 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5282 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5283 2006-04-01.
5285 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5286 Clean up _AC_COMPILER_EXEEXT* macros.
5287 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5288 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5289 ac_file to the name of the default output file and call
5290 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5291 initial `rm' of the candidate files...
5292 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5293 the same list in subsequent `rm' calls, and for the temporary
5294 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5295 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5296 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5297 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5298 no longer needed) by libtool. Make it a cache check.
5299 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5300 copied here by mistake.
5301 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5302 _AC_COMPILER_EXEEXT.
5303 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5304 _AC_COMPILER_OBJEXT directly.
5305 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5307 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5309 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5310 Fix description of how the buggy `sed' works.
5312 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5314 Sync from Automake:
5316 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5317 ENOLCK. Only mention `make -j' when applicable. Only raise
5318 fatal errors when `make -j' is involved. Improve error message.
5320 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5322 * doc/autoconf.texi (Here-Documents): We now know more about
5323 the variable expansion in here documents bug.
5324 Thanks to Tim Rice and Stepan Kasal.
5326 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5327 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5329 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5331 * tests/autotest.at (Multiline command from M4 expansion):
5332 No failure to be expected if the shell quotes newlines in
5333 commands in the `set -x' output. Report by Tim Rice.
5334 * THANKS: Update.
5336 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5338 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5339 expansion in the here-documents used by config.status, as that
5340 runs afoul of the Korn shell version M-12/28/93d bug described in
5341 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5342 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5343 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5345 2006-05-23 Jim Meyering <jim@meyering.net>
5347 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5348 Fix typo introduced with 2006-04-02 change. It reversed the sense
5349 of the test.
5351 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5353 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5354 ac_dB slightly, to save bytes in the script.
5355 Max out at 50 lines, rather than 96; this is more likely
5356 (though not guaranteed) to avoid obscure 'sed' failures.
5358 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5360 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5361 `tr -d -' as bad option argument. Work around this by deleting
5362 an unrelated character.
5363 Report by Tim Rice <tim@multitalents.net>.
5365 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5366 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5367 Stepan Kasal <kasal@ucw.cz>
5369 * doc/autoconf.texi (Particular Programs): Do not promise that
5370 we always prefer the GNU version of the program, and that we
5371 search according to PATH; both rules can have exceptions.
5372 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5373 AC_PROG_SED. Move descriptions of limitations
5374 to the Limitations of Usual Tools section.
5375 (Limitations of Usual Tools) <sed>: Mention script length
5376 limitations with Solaris /usr/ucb/sed.
5377 <grep>: Fix wording for empty alternative. Mention that -c and
5378 -l should not be combined, and that -E and -F should not be
5379 combined.
5381 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5382 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5384 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5385 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5387 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5389 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5390 AC_DEFINE is now passed to m4_pattern_allow.
5391 * NEWS: Mention that; likewise for AC_SUBST.
5392 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5393 the parameter to m4_pattern_allow.
5394 * tests/tools.at: Add a check for that.
5396 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5398 * lib/autoconf/status.m4: Fix typos.
5400 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5402 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5403 only the files that this macro generates.
5405 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5407 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5408 the HP-UX sed limitation of 99 commands, labels do not count.
5409 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5410 in the comment.
5411 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5413 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5415 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5416 Import the following fix from coreutils:
5418 2006-01-13 Jim Meyering <jim@meyering.net>
5420 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5421 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5422 not double-quote uses of that variable, to accommodate the rare
5423 case in which getmntent is available in none of the libraries
5424 checked. This happens at least on FreeBSD 5.0.
5426 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5428 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5429 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5430 some other programs unwisely rely on these undocumented vars.
5431 But put in warning comments about them.
5432 Problem reported by Ralf Wildenhues in
5433 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5434 * NEWS: Document that these variables are intended to go away.
5436 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5438 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5439 and set the language to C++ (analogous to the equivalent Fortran
5440 tests).
5442 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5443 * doc/autoconf.texi (C++ Compiler): Document it.
5444 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5445 * NEWS: Update.
5447 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5449 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5450 that caused config.status to generate 100-command sed scripts; the
5451 portable limit is 99.
5453 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5455 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5456 variable `ac_d' instead of `d' to avoid infringing namespace.
5457 Report by Ralf Menzel.
5459 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5461 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5462 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5463 * tests/tools.at (autoconf: subdirectories): New test, taken from
5464 the corresponding problem report by Ralf Wildenhues in:
5465 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5467 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5468 Quote some uses of shell variables if they might suffer unexpected
5469 globbing. This doesn't fix all instances of quoting problems that
5470 I found, just the easy ones that look safe.
5471 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5472 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5473 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5474 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5475 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5476 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5477 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5478 Likewise.
5479 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5480 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5482 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5484 * bin/autoreconf.in ($help): Reword according to the manual.
5485 Suggested by Olly Betts.
5487 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5488 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5490 * bin/autoreconf.in: Pass the directory argument to
5491 `require_configure_ac'. Fix comment.
5492 * tests/torture.at (Configuring subdirectories): Expose this.
5493 Reported by Olly Betts.
5495 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5497 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5498 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5499 Automake as follows:
5501 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5502 `$configure_in' instead of `configure.in', to preserve
5503 directory component.
5505 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5507 * config/config.guess, config/config.sub, config/texinfo.tex,
5508 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5510 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5512 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5513 test for C99 conformance; (bool) 0.5 is an integer constant
5514 expression, but (bool) -0.5 is not. Problem reported by Fedor
5515 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5517 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5519 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5520 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5521 Warn about obsolete install-sh files. Remove stray sentence
5522 fragment and fix cross reference.
5523 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5524 install -d; this undoes the 2006-05-10 change.
5525 (MKDIR_P): Mark with AN_MAKEVAR.
5526 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5527 that we don't require $INSTALL to be thread-safe. Move comments
5528 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5529 of AC_PROG_INSTALL. Output a message saying that we're checking
5530 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5531 MKDIR_P instead of AC_SUBST.
5532 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5533 Special magic for MKDIR_P, too.
5534 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5535 a dnl.
5536 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5538 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5540 Sync from Automake, as follows:
5542 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5543 * config/install-sh: Initialize IFS, so field splitting isn't
5544 turned off later.
5545 * config/mkinstalldirs: Likewise.
5546 * config/missing: Remove superfluous quotes. Replace all uses of
5547 `[' by `test', for consistency, and for..
5548 * config/missing (sed_minuso, sed_output): New variables.
5549 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5550 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5551 Fixes `missing' to detect `--output' for help2man. Fixes
5552 PR automake/483. Report by Dennis J. Linse.
5553 (autom4te): Document in `missing --help'.
5555 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5557 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5558 * config/install-sh: Don't use 'path' to talk about file names,
5559 as per GNU coding standards. Close a race condition reported by Ralf
5560 Wildenhues and Stepan Kasal. There is still a race condition
5561 on hosts that predate Posix 1003.1-1992, but we can't help this.
5562 Don't mishandle weird characters like space on pre-Posix hosts.
5563 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5564 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5565 AC_PROG_MKDIR_P from AS_MKDIR_P.
5566 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5567 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5568 earlier editions are not (including Automake 1.8.3).
5569 Do not suggest mkinstalldirs for thread-safety.
5570 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5571 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5572 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5573 presence of special characters and race conditions.
5574 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5575 in Autoconf's name space.
5577 2006-05-10 Bruno Haible <bruno@clisp.org>
5578 and Paul Eggert <eggert@cs.ucla.edu>
5580 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5581 from Automake with minor changes.
5582 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5584 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5586 * config/install-sh: Update to Automake CVS version, as follows:
5587 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5588 * lib/install-sh: Simplify the expr implementation of dirname.
5589 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5590 * lib/install-sh: Handle --, and diagnose unknown options.
5592 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5594 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5595 `./autom4te' to create `./testsuite', since the `all' target
5596 will ensure its presence, but `installcheck' should not create
5597 the uninstalled wrappers.
5599 * tests/torture.at (Unusual Automake input files): Skip if we
5600 detect automake < 1.8.
5602 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5604 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5605 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5606 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5607 * NEWS: Update.
5609 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5611 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5612 munge (multiple) white space and other oddities.
5613 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5614 single quotes in variable assignment.
5615 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5616 and similar failures by adding multiple spaces, tabs, and other
5617 special characters.
5618 Report and different test suggested by Francesco Romani
5619 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5621 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5622 single quotes, we only need to search for single quotes; this
5623 both simplifies the search pattern, and makes us less
5624 susceptible to `echo' variations for arguments not containing
5625 single quotes.
5626 (_AC_ARG_VAR_VALIDATE): Likewise.
5628 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5630 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5631 `$*' and IFS concatenation issue with traditional shells and
5632 bash-2.04. Report by Seanster@Seanster.com.
5634 2006-05-03 Bruno Haible <bruno@clisp.org>
5636 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5637 precisely which Mac OS X versions have the od problem.
5639 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5641 * doc/autoconf.texi: Use @option systematically.
5643 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5644 and Bruno Haible <bruno@clisp.org>
5646 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5647 about 'od'.
5648 (Integer Overflow): Mention the special case of integer division
5649 overflow.
5651 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5653 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5654 traditional shells like the Solaris one that do not use the
5655 first IFS character for assembling `$*'.
5656 Prompted by a related report from autoconf_bug@nro.ca.
5658 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5659 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5661 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5662 Mention more problems with the -e option.
5664 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5666 * NEWS: Typo.
5667 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5669 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5670 in URLs to improve DVI formatted output (requires texinfo 4.6).
5671 (System Services, Systemology, Shellology): Likewise.
5672 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5673 output.
5675 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5676 continuous text.
5677 (Runtime): Fix macro argument names to match description:
5678 `action-if-found' -> `action-if-true' and similarly.
5679 (Obsolete Macros): Likewise.
5680 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5681 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5682 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5684 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5686 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5688 * ChangeLog: Typo.
5689 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5690 DVI output.

5695 /bin/sh set unsorted output.
5696 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
5697 * tests/local.at: Likewise.
5699 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
5701 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
5702 (Integer Overflow, Null Pointers, Buffer Overruns):
5703 (Floating Point Portability, Exiting Portably): New sections.
5704 (Writing Test Programs): Fix some langauge. Recommend exiting
5705 with status 1, not merely nonzero. Clarify exit declaration.
5706 (Run Time): Move C exit status stuff to new Exiting Portably section.
5707 (Systemology): Mention Posix and levenez. Update v7 reference.
5708 (Portable Shell): Mention the Posix shell.
5710 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5712 * bin/autoconf.as (me): Replace by as_me.
5714 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5716 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5717 since as_me isn't set yet.
5719 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5721 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5722 a few minor bugs in this area.
5724 * doc/autoconf.texi (Programming in M4sh): Comment out the
5725 documentation of AS_BASENAME, for now.
5726 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5727 (Limitations of Builtins) <basename>: Do not refer to
5728 AS_BASENAME.
5729 * bin/autoconf.as (me): Don't use AS_BASENAME.
5730 (dir): Remove the unused variable.
5731 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5732 AS_DETECT_REQUIRED. All uses changed.
5733 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
5734 All uses changed.
5735 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
5736 (AS_BASENAME): Use "basename --" to protect against leading "-".
5737 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
5738 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
5739 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
5740 (_AS_DIRNAME_PREPARE): Likewise.
5741 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
5742 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5743 (AS_DIRNAME): Use "dirname --".
5745 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5747 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5748 of "run time" and "run-time" changed to "runtime", for consistency.
5749 * lib/autoconf/fortran.m4: Likewise (in comment).
5750 * lib/autoconf/functions.m4: Likewise.
5751 * lib/autoconf/general.m4: Likewise.
5752 * lib/autoconf/headers.m4: Likewise.
5754 * doc/autoconf.texi (Run Time): Document the exit status situation
5755 with more accuracy and detail.
5757 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5759 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5760 Archive is not officially `GNU' any more. Update URL.
5761 (Defining Directories): Likewise
5762 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5764 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5766 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5767 newline from the `trap' code to finish `config.log'; the NetBSD
5768 /bin/sh resets the exit status after an empty command, as
5769 documented in doc/autoconf.texi.
5770 Reported by Dalibor Topic <robilad@kaffe.org>.
5772 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5774 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5775 Suggested by Bruno Haible.
5777 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5779 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5780 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5781 Instead, just list the shells that we know work.
5782 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5783 changed. Be more cautious about the _cv_ variable.
5784 * tests/tools.at (Syntax of the shell scripts): Check the
5785 _cv_ variable once, at first, to avoid an internal autoconf error
5786 when sh -n does not work.
5788 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5790 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5792 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5794 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5795 use ">&-" since we're only 99.999% sure that this is portable,
5796 and since the MinGW bug is fixed in a different way.
5797 * lib/autotest/general.m4 (AT_INIT): Likewise.
5799 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5801 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5802 before opening config.log, to avoid hitting a bug on MinGW.
5804 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5806 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5807 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5808 This works around a MinGW bug reported by Eric Paire.
5809 Make sure that all writes to the log file append to it,
5810 rather than possibly losing data.
5811 * lib/autotest/general.m4 (AT_INIT): Likewise.
5813 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5815 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5816 description.
5818 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5820 * NEWS: Update.
5822 * configure.ac (AC_INIT): Bump to 2.59d.
5824 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5826 Version 2.59c.
5828 * Makefile.maint (news-date-check): Do not require a leading `*'
5829 before the release date in NEWS.
5831 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5832 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5834 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5835 the instantiated file do not contain the string 'datarootdir'
5836 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5837 @mandir@, replace the reference '${datarootdir}' by the value.
5838 * tests/torture.at (datarootdir workaround): New test.
5839 * NEWS: Advertise this temporary fixup.
5840 Based on a patch by Bruno Haible, reported and analyzed by
5841 Paul Eggert and Noah Misch.
5843 2006-04-12 Eric Blake <ebb9@byu.net>
5845 * tests/autotest.at (Debugging a failed test): Fix comment.
5847 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5849 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5850 all the changes since 2006-04-07.
5852 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5854 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5855 succeeded, but `ln -s file dir' failed, take care to remove the
5856 leftover target before the next test, to prevent its spurious
5857 failure; also make sure `ln file dir' works before selecting it.
5858 Thanks to Keith Marshall for pointing this out.
5859 * THANKS: Update.
5861 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5862 assignments in `at_debug_args', so that we put them correctly
5863 in the `run' script.
5864 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5865 Reported by Eric Blake.
5867 2006-04-11 Eric Blake <ebb9@byu.net>
5869 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5870 top-level tests after micro-suite has been run. Used in...
5871 (Debugging a successful test, Debugging script and environment),
5872 (Debugging a failed test): ...these new tests. The first of these
5873 is fixed by...
5874 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5875 macro, split out from...
5876 (AT_INIT): ...here, so that using -d also generates a run script.
5877 Document that -d inhibits top-level logging.
5878 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5879 inhibits top-level logging; debug scripts are created.
5881 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5882 check.
5883 * tests/autotest.at (Empty test, Empty check): New test to check it.
5885 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5886 from gcc.
5888 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5890 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5891 the files if a problem appears. Make the empty *.at files
5892 read-only, too. Proposed by Ralf Wildenhues.
5894 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5896 * config/Makefile.am: Add comment to force updated Makefile.in.
5898 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5899 space only patch to this file, this patch causes the Makefile.in
5900 files that include freeze.mk to be updated, and thus have a
5901 newer time stamp again, which in turn makes a pristine CVS
5902 checkout have correct time stamps.
5904 * Makefile.maint (cvs-sv): New macro, to be used..
5905 (config.guess-url_prefix, config.sub-url_prefix)
5906 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5907 point to CVS text checkout of Gnulib files.
5908 (copyright-check): Bump current year.
5909 (announcement): Do not hard-wire `./announce-gen'.
5910 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5911 correctly.
5912 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5913 `chmod +x'.
5914 (wget_files): Update config.guess, config.sub, texinfo.tex by
5915 `wget-update', now that their URLs work again.
5917 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5919 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5920 Problem noted by Paul D. Smith.
5922 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5924 * doc/autoconf.texi: Remove unused words from word list.
5925 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5926 .x-sc_trailing_space: New files.
5928 * doc/standards.texi: Sync from gnulib.
5930 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5931 `LIBOBJDIR' as experimental.
5933 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5934 with a target directory; it's internally implemented as `cp'
5935 anyway, but since Autoconf advertises the possibility to use
5936 a target directory when LN_S is `ln -s', we need to find out.
5937 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5938 analyzed by Keith Marshall <keith.marshall@total.com>.
5940 * THANKS: Update.
5942 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5944 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5945 confdefs.h as-is. In general, if it has backslash-newline or the
5946 like, then it doesn't work either to sort or to remove empty
5947 lines.
5949 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5951 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5953 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5955 * lib/autom4te.in (Automake-preselections): Preselect
5956 _AM_SUBST_NOTMAKE.
5958 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5960 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5961 apostrophe within a single-quoted string, as this is the usual
5962 tradition and is easier to read than '"'"'. Don't rely on the
5963 shell treating "$/" like '$/'. Use a more-consistent indenting
5964 style for the trap.
5966 2006-04-09 Eric Blake <ebb9@byu.net>
5968 * tests/autotest.at (Backquote command substitution),
5969 (Multiline backquote command substitution): Remove mistaken
5970 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5971 applied...
5972 (Parenthetical command substitution, Multiline parenthetical
5973 command substitution): here.
5975 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5977 Import macros from gnulib (often changing their name).
5979 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
5980 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
5981 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
5982 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
5983 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
5984 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
5985 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
5986 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
5987 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
5988 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
5989 The manual mentions Gnulib more prominently.
5990 * doc/autoconf.texi (Gnulib): New node.
5991 (Pointers): Add Gnulib URL.
5992 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
5993 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
5994 Gnulib section.
5995 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
5996 suggest a #define rather than a typedef for _Bool, and mention
5997 Gnulib rather than trying to substitute stdbool code.
5998 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
5999 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
6000 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
6001 AC_STRUCT_DIRENT_D_TYPE.
6002 (Particular Types): Mention stdint.h and inttypes.h as standard
6003 headers too.
6004 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
6005 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
6006 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
6007 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
6008 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6009 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6010 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6011 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6012 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6013 (Coding Style). Don't mention m4_expand_once.
6014 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
6015 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.

6052 Revert the patch from 2006-04-01 and only improve
6053 _AS_DETECT_BETTER_SHELL:
6055 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6056 skip nonexistent directories.
6057 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6058 only shell candidates which exist.
6059 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6060 * lib/autotest/general.m4 (AT_INIT): No need to give three
6061 parameters to _AS_PATH_WALK.
6063 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6064 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6066 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6067 distinguish m4sugar macros.
6068 * tests/tools.at (autoupdating with aclocal and m4_include):
6069 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6070 test case by Noah Misch <noah@cs.caltech.edu>.
6072 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6074 Revert my change from 2006-03-17, in other words:
6075 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6076 and DUALCASE=1.
6077 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
6078 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
6079 it is set.
6081 2006-04-07 Eric Blake <ebb9@byu.net>
6083 * doc/autoconf.texi (Programming in M4sh): Document that
6084 AS_MKDIR_P exits the script on failure.
6085 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6087 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6089 * config/elisp-comp, config/install-sh, config/mdate-sh,
6090 config/missing, config/mkinstalldirs: Sync from Automake.
6092 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
6093 from Automake.
6095 * doc/make-stds.texi: Sync from gnulib.
6097 2006-04-06 Eric Blake <ebb9@byu.net>
6099 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6100 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

6106 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6108 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6109 whether `set' quotes correctly: redirect stderr of the tested
6110 `set', and use a subshell, for Ultrix; use `sed' instead of
6111 `grep' for zsh `set' which may write binary output; match only
6112 at the beginning of a line, to avoid false positives.
6113 In order to avoid false positives by unrelated variables with
6114 multiline content, put the dump algorithm in a subshell and
6115 unset all variables containing newlines (except some which are
6116 special to the shell). Warn about cache variables that are
6117 unset.
6119 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6121 * config/config.guess, config/config.sub, config/texinfo.tex:

6129 (AC_ARG_VAR): Do test this now.
6130 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6131 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6132 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6133 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6135 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6136 shell issue with double-quoted command substitutions of native
6137 commands.

6139 Marshall.
6141 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

6158 * tests/Makefile.am (maintainer-check-posix):
6159 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6161 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6162 ac_config_<foo>s again, sometimes normalized, sometimes not.
6163 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6164 (AC_CONFIG_COMMANDS): Do not do so here.
6165 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6166 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6167 2005-07-25 rewrite. Noticed by Noah Misch.
6169 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6170 _AC_PRESERVE_HELP_ORDER, ...
6171 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6173 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
6174 inside m4_expand_once; it is redundant.
6176 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6177 for --help from Cygnus `configure.'
6179 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6189 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
6190 Noah Misch <noah@cs.caltech.edu>
6192 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
6193 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
6194 * doc/autoconf.texi (Help Formatting): New node.
6195 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
6197 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6199 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
6200 lib/autoconf/specific.m4, lib/autoconf/status.m4,
6201 lib/autoconf/types.m4, lib/autotest/general.m4,
6202 tests/mktests.sh, tests/torture.at: White space cleanup:
6203 remove some SPACE before TAB, or add quoting ('' or @&t@).
6205 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
6207 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
6209 2006-04-05 Eric Blake <ebb9@byu.net>
6211 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
6212 empty test suite works.
6213 * tests/autotest.at (Empty test suite): Remove xfail.
6215 2006-04-05 Noah Misch <noah@cs.caltech.edu>

6218 TAGS to ac_config_<foo>s.
6219 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
6220 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
6221 normalizing it, consistent it with previous releases.
6222 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
6224 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6226 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
6227 Use simplified args that Eric Blake originally suggested.
6229 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6231 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6232 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6233 Use 'comm' rather than N instances of grep; this also fixes a bug
6234 whereby substrings were incorrectly matched, causing us to not
6235 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6236 (exclude_list): Exclude empty macros.
6237 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
6239 Use awk rather than grep -E or egrep, to avoid
6240 portability problems with regular expressions containing newlines.

6242 Switch from grep to awk syntax.
6243 (ac_exclude_script): Renamed from ac_exclude_egrep.
6244 (au_exclude_script): Renamed from au_exclude_egrep.
6246 2006-04-04 Noah Misch <noah@cs.caltech.edu>
6248 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
6249 a subdirectory subject to Cygnus `configure'.
6250 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
6252 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
6253 report request when we have no AC_PACKAGE_BUGREPORT.
6255 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6257 * THANKS: Update.

6260 generated files.
6262 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
6263 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
6264 typedef'ed restricted pointer, to catch a compiler bug on
6265 HP-UX 11.x, and fix warnings so it passes with -Werror.
6266 (_AC_PROG_CC_C99): Likewise.
6267 Reported by Albert Chin <china@thewrittenword.com>.
6268 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

6283 * THANKS: Add myself.
6285 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6287 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
6288 to log, point to testsuite output tree.
6290 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>

6297 Remove; all uses removed.
6298 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

6318 Clean up _AC_COMPILER_EXEEXT* macros.
6320 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6321 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6322 ac_file to the name of the default output file and call
6323 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6324 initial `rm' of the candidate files...
6325 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6326 the same list in subsequent `rm' calls, and for the temporary
6327 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6328 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6329 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6330 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6331 no longer needed) by libtool. Make it a cache check.
6332 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6333 copied here by mistake.
6334 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6335 _AC_COMPILER_EXEEXT.
6336 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6337 _AC_COMPILER_OBJEXT directly.

6368 * lib/autoconf/general.m4 (_AC_INIT_VERSION): Emit script name and
6369 Autoconf version number despite a zero- or one-argument AC_INIT.
6371 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
6372 subordinate tools.
6373 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
6374 * doc/autoconf.texi (autoreconf Invocation): Document it.
6376 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
6377 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

6385 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6387 * bin/autoupdate.in: Redefine m4_location so that warnings print
6388 the correct lines of the input file by subtracting..
6389 (_au__first_line): ..this new definition.
6391 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
6392 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
6393 Remove stray newline in output.
6394 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
6395 AC_DEFUN this for autoconf, including the obsoletion diagnose.
6396 Fixes autoupdating of code where the replacement output contains
6397 m4sugar macros.
6398 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
6399 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

6401 * tests/tools.at: Several new tests for all of this.
6402 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
6403 hairy details.
6404 The AC_LANG_SAVE issue was reported against Libtool by
6405 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
6406 Kristian Kvilekval <kris@cs.ucsb.edu>.
6408 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6410 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
6411 switch all of them on and of when necessary. Fixes the bug when
6412 m4sugar macros (e.g., m4_define) were expanded after the first
6413 automatic update (e.g., after AC_PREREQ or AC_INIT).
6415 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

6440 aclocal cannot be given on the command line.
6442 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
6444 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
6445 Give an example for AS_DIRNAME instead of referring to Posix..
6446 (File System Conventions): Put discussion of // versus / here, and
6447 modernize it a bit.
6448 (Limitations of Usual Tools): Add basename. Remove verbiage
6449 after dirname, since it got moved to the above sections.
6450 All this was inspired by a patch proposed earlier by Eric Blake.
6452 2006-03-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7109 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7110 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7111 by the function rather than ignoring it.
7112 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7113 comparing its address. Intel's interprocedural optimization was
7114 outsmarting the old heuristic. Problem reported by
7115 Mikulas Patocka.

7119 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

7126 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7128 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7129 before removing it (chmod -R u+rwx); there are three instances of this.
7131 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7132 Stepan Kasal <kasal@ucw.cz>
7134 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7135 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7136 make its content writable before removing it. Remove an errorneous
7137 comment from the end, where the logs of the failed tests are copied
7138 to the main log file.
7140 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7142 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7143 in case the computer is too quick. Double quote the configure.ac
7144 snippets.
7146 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7147 problems if the testsuite were running too fast.
7149 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7151 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7152 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7153 (which belong to Xt, not X itself). See Debian bug 327655.
7154 * NEWS: Mention this.
7156 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7158 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7160 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7162 * config/move-if-change: Don't output "$2 is unchanged";
7163 suggested by Ben Elliston. Handle weird characters correctly.
7165 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7167 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7168 calls, so that the final expansion of this macro is shorter.
7169 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7170 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7171 the cleanup there. Use AS_VAR_* macros, to be more general.
7172 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7174 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7176 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7178 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7180 * doc/autoconf.texi (Configuration Headers): Add an index entry
7181 for AH_HEADER.
7183 2005-08-26 Pavel Roskin <proski@gnu.org>
7185 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
7186 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7187 running xmkmf.
7189 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7191 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7192 The previous patch didn't work, so try a better one.
7194 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7196 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7197 in the example. Reported by Bruno Haible.
7198 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7199 "if $undefined_var;" succeeds with my shell.
7201 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7202 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7203 but change the m4_divert_text to m4_divert_once.
7205 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7207 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7208 Work around bug in Solaris /usr/xpg4/bin/awk.
7209 The bug is present in at least Solaris 8 through 10.
7211 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7213 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7214 some evil values and relying on the fact that $* concatenates the
7215 parameters by the first character from IFS.
7217 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7218 Stepan Kasal <kasal@ucw.cz>
7220 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7221 first header appears, define AH_HEADER.
7222 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7223 Update limitations about when to call AC_CONFIG_HEADERS.
7224 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7225 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7226 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7227 ``Configuration Actions''; fix their index entries.
7229 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7230 options correctly. Process N-M as M-N if M is smaller than N.
7231 Process ranges correctly so that N-N will run only N.
7232 Sort and uniquify the tests that will be run. If there is more
7233 than one test, reinsert the banners for the tests.
7234 * tests/autotest.at (Keywords): Unmark XFAIL.
7236 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7238 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7239 before passing the macro name to AH_TEMPLATE.
7241 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7242 now opens log after option processing; in particular, --version
7243 and --help do not touch config.log.
7245 * Makefile.maint: Revert the change from 2005-08-12.
7247 2005-08-22 Stepan Kasal <kasal@ucw.cz>
7249 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
7250 common code to...
7251 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
7253 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7255 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7256 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7257 Language cleanup.
7259 * doc/autoconf.texi (Defining Symbols, Changed Results):
7260 Prepend to LIBS, not append, in examples.
7262 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7264 When building in place, set srcdir="."; suggested by Tim Van Holder.
7266 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7267 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7268 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7269 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7270 does not mean "no --srcdir option".
7272 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7274 * tests/autoscan.at (autoscan): New file.
7275 * tests/suite.at: Use it.
7276 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7277 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7279 * tests/autotest.at (Keywords): Test keywords combinations.
7281 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7283 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7284 add "2>&1"; gzip 1.2.4 prints help on stderr.
7286 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7288 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7289 was pushdef'ed twice while popped only once. Push it only once.
7290 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7292 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7294 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
7295 prefixed by mere "===", not "configure: === ".
7297 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
7299 * Makefile.maint: Update from Bison.
7301 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7302 "<tab>" in comment, so that the point is understandable.
7304 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7306 Rewrite substantial part of lib/autoconf/status.m4.
7307 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7308 and CONFIG_COMMANDS are not processed in four separate loops.
7309 Instead, there is one main loop. This alows that the common code
7310 is expanded only once, thus config.status (and configure) is smaller.
7312 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7313 the AC_LIST_FILES and cousins macros are no longer used.
7315 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7316 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7317 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7318 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7319 contain the initialization, nor the for loop, nor the associated
7320 commands; all these go to ...
7321 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7322 _AC_OUTPUT_CONFIG_STATUS.
7323 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7324 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7325 (_AC_OUTPUT_FILE): The creation of the sed script ...
7326 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7327 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7328 _AC_OUTPUT_MAIN_LOOP.
7329 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7330 _AC_CONFIG_COMMANDS): Use ...
7331 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7332 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7333 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7334 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7335 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7336 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7337 ... new macros.
7338 (_AC_CONFIG_UNIQUE): Update.
7339 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7340 Replaced by this ...
7341 (_AC_LIST_TAGS): ... new common macro.
7342 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7343 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7344 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7345 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7346 this didn't belong to the `config commands' section.
7347 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7348 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7349 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7350 to the `config commands' section either.
7351 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7352 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7354 ... and many changes to the comments nearby.
7356 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7357 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7358 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7359 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7360 (#define header templates): The comment at the top of the generated
7361 header now includes the name(s) of the source file(s).
7363 Several unrelated small changes:
7365 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7366 parameter to AC_DIAGNOSE.
7367 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7368 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7369 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7370 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7371 with AU::AC_OUTPUT.
7372 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7373 in AC_OUTPUT doesn't double-quote it either.
7374 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7375 parameters.
7377 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7379 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which

7414 to INIT_PREPARE.
7415 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign

7469 configure_input, top_builddir, srcdir, etc.
7470 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7471 PATH_SEPARATOR in AUTOTEST_PATH.
7473 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

7507 for --help in that case.
7509 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7510 matches the order of execution. No code changed.

7532 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7533 (AC_SUBST): Call it.
7534 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7535 the directory specific variables; but don't call it for configure_input.
7537 2005-06-28 Derek Price <derek@ximbiot.com>
7539 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7540 addition.
7542 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

7563 variable into diagnostic. Make the diagnostic an error, not a warning,
7564 because we really don't support spaces and suchlike in dir names.
7565 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7566 Don't worry about backslashes in srcdir; it can't happen now.

7594 b, t, r, w commands require single space, while : cannot have any.
7595 (Special Shell Variables): Fix sed code this in the example.
7596 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7597 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
7599 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

7609 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
7610 * doc/autoconf.texi:
7611 Don't mention Solaris versions so much, if a
7612 problem is common to all extant versions of Solaris. Say "SunOS
7613 4" instead of "SunOS" for SunOS 4.
7614 (awk): Mention more of the limitations of traditional Awk.
7615 (cat): Don't talk about cat -v.

7622 to be compatible with glibc strverscmp.
7623 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
7625 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

7655 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
7657 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff

7659 Problem reported by Ralf Menzel.
7661 2005-06-08 Derek Price <derek@ximbiot.com>
7663 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7664 renaming them since they are about to be redefined anyhow.
7666 2005-06-08 Derek Price <derek@ximbiot.com>

7669 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7670 Move m4_undefine to alphabetical order.
7672 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>

7675 * doc/autoconf.texi (Introduction): Likewise.
7676 Reword to avoid some formatting glitches.

7679 Redo example output tp match current CVS snapshot.
7680 Use @example.org in email addresses when the examples
7681 might get inadvertently cut-and-pasted into user code.
7682 Remove example of autom4te usage that doesn't seem to work now.
7683 Use modern AC_INIT (except when the example is meant to be
7684 shown with Autoconf 2.13).
7685 Update ksh info for Solaris 9 and later.
7686 KB -> kB.

7698 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7699 Tru64 ksh pattern matching bug. Reported against Libtool by
7700 Albert Chin <libtool@mlists.thewrittenword.com> and
7701 Nicolas Joly <njoly@pasteur.fr>.
7703 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7705 m4_cdr of one-member list was [[]] (one-member list containing an
7706 empty string) instead of [] (an empty list. Callers were skewed to
7707 match this misbehaviour. As a consequence of this:
7708 - m4_foreach([x], [], [foo]) expanded to `foo', while
7709 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7710 This bug has been fixed:
7712 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7713 expand to an empty string; print error msg if called without
7714 an argument list.
7715 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7716 misbehaviour; handle [] and [[]] correctly.

7724 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7726 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7727 swallow records with more than 99 fields.
7728 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7729 parse the long line.
7731 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7733 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7734 swallow literals longer than 399. Reported by Ralf Wildenhues.

7746 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7747 (DISTCLEANFILES): Remove $(check_SCRIPTS).

7766 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7768 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7769 now contain newlines, and substituted files must be referenced on
7770 a line alone; the sed scripts to substitute them are now very
7771 different.

7773 commands can be put in a sed script portably.
7774 * doc/autoconf.texi (Setting Output Variables): Document above

7787 classes in shell scripts. The test was too brittle.
7789 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7791 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

7825 (ac_top_build_prefix): ... to this; the old name is also kept, for
7826 backward compatibility.

7843 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7844 argument to m4_foreach. I guess it was necessary in the past,
7845 but I think it's a no-op now.
7847 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7849 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7850 ``cat <<_ACEOF'' commands to one.
7851 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
7852 * lib/autoconf/status.m4: On various places, use expr instead of
7853 ``echo|sed.''
7854 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
7855 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
7856 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7857 a range.
7858 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
7859 the wrong patterns between ``case'' and ``esac.'' The previous
7860 code had false positives.
7862 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
7864 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
7865 as on 2005-05-02.
7866 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
7867 Mention LIBOBJDIR.

7907 2005-05-13 Stepan Kasal <kasal@ucw.cz>
7909 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
7910 check.
7911 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
7912 enough arguments, similarly as in m4_bpatsubsts.
7914 2005-05-12 Stepan Kasal <kasal@ucw.cz>
7916 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
7917 of absolute paths.
7919 2005-05-11 Stepan Kasal <kasal@ucw.cz>
7921 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
7922 for absolute directory names in one loop.
7923 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
7924 abbreviations of --version and --debug.
7926 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
7928 * doc/autoconf.texi (Autoconf Language): Be more precise about
7929 quoting rules. Problems noted by Stepan Kasal.
7930 Also, throughout this document, be more careful about white space.
7931 "blank", "white space", and "space" all have different meanings
7932 and we should be careful to say what we mean.
7934 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
7936 Fix C++ related problems reported by Werner Lemberg.
7937 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
7938 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
7939 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
7940 avoid problems with C++ and throw.
7941 * tests/compile.at: .cpp, not .cc.
7943 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
7945 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7947 * doc/autoconf.texi (Generic Functions): Typos.
7949 2005-05-02 Gary V. Vaughan <gary@gnu.org>
7951 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
7952 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
7953 set by latest automake.
7955 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7957 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
7958 outputs 0 on GNU/Linux these days.
7960 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
7962 * doc/autoconf.texi (Autoconf Language): Add more description
7963 about quoting heuristics.
7964 (Limitations of Builtins): Describe "set -" problems.
7966 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7968 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
7969 not newline.
7971 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
7972 by AC_DEFINE; it was a mistake.
7973 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
7975 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7977 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7979 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7981 * doc/autoconf.texi (External Software): Quadrigraphs are not
7982 processed correctly in AS_HELP_STRING; avoid this in the examples.
7983 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7984 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7985 comment and reduce m4_default([foo], []) to [foo].
7986 (m4_strip): Update the explanation.
7988 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7990 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7991 Remove core.conftest.* too; it's generated by Tru64 5.1.
7992 Problem reported by Jennis Pruett.
7993 * lib/autoconf/functions.m4
7994 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7995 Don't bother to remove core files; AC_RUN_IFELSE should do that
7996 for you.
7998 2005-04-19 Stepan Kasal <kasal@ucw.cz>
8000 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
8002 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
8004 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
8005 Report from Horst Wente.
8007 2005-04-15 Stepan Kasal <kasal@ucw.cz>
8009 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
8010 the comment.
8012 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
8014 * doc/autoconf.texi (External Software, Package Options): Add
8015 examples showing how to implement --with-* and --enable-* options.
8017 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8019 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8020 as well as configure.in. Problem reported by Gregorio Guidi.
8022 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8024 * doc/autoconf.texi (Particular Functions): Use gnulib's current
8025 pattern for alloca snippet.
8027 2005-04-04 Stepan Kasal <kasal@ucw.cz>
8029 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
8031 2005-04-01 Stepan Kasal <kasal@ucw.cz>
8033 * doc/autoconf.texi (Generic Programs): Fix a typo.
8035 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
8037 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
8038 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
8040 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8042 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8043 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8044 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8045 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8046 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8048 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8050 * NEWS: The configure command now warns you if you attempt to use
8051 a directory whose name contains a special character like space,
8052 newline, or "\".
8053 * doc/autoconf.texi (Installation Directory Variables): Allow
8054 "," in file names. Do not use \@; it's not a portable regexp.
8055 * bin/Makefile.am (edit): Likewise.
8056 * lib/Makefile.am (edit): Likewise.
8057 * tests/Makefile.am (edit): Likewise.
8058 * tests/semantics.at: Likewise.
8059 * tests/torture.at: Likewise.
8060 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
8061 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
8062 * doc/autoconf.texi (File System Conventions): Warn about
8063 unportable file names.
8064 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8065 (AC_INIT): Use it.
8066 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8067 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8068 ac_pwd, and quote srcdir.
8069 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8071 * doc/autoconf.texi: Fix some systematic formatting problems.
8072 ".)" needs a following @: if not at the end of a sentence, and
8073 similarly for "!)". "etc." should be preceded by a comma.
8074 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8076 2005-03-22 Bruno Haible <bruno@clisp.org>
8078 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8079 argument is often called 'build-aux'.
8081 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8083 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8084 macro AC_TRY_LINK is obsolete.
8085 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8086 `AC_CONFIG_FILES'.
8088 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8090 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8091 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8092 from a Common Lisp's `cl'.
8093 (AC_PROG_CXX): Behave according to the documentation: don't
8094 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8095 make the variable CCC precious; use `cl.exe', not `cl'.
8097 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8098 Alexandre Duret-Lutz <adl@gnu.org>
8100 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8101 /dev/null, as "configure" shouldn't read stdin, and this insulates
8102 us from problems (e.g., when testing for "cl"). Also, do this
8103 redirection before invoking "hostname" or "uname", and keep the
8104 original input stream available via...
8105 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8106 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8107 bother with "</dev/null" since it's now done at the top of
8108 'configure'.
8109 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8110 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8111 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8112 * doc/autoconf.texi (File Descriptor Macros): New section.
8113 (Printing Messages): Mention it.
8114 * tests/base.at (Input/Output): New test.
8116 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8118 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8119 newline if neither \c nor -n work, as that would output two
8120 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8122 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8124 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8125 This causes that any required macros inside will get before the if.
8126 * doc/autoconf.texi (autom4te.cache): A typo.
8128 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8130 Undo previous change, except keep the change to
8131 lib/autoconf/programs.m4 that replaced grep with shell
8132 pattern-matching. This is because net-snmp configure reads stdin.
8133 Reported by Noah Misch.
8135 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8137 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8138 from /dev/null, as "configure" shouldn't read stdin, and this
8139 insulates us from problems (e.g., when testing for "cl").
8140 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8141 before invoking "hostname" or "uname".
8142 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8143 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8144 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8145 "</dev/null" since it's now done at the top of 'configure'.
8146 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8147 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8148 Also, replace grep with shell pattern-matching, to save a process.
8150 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8152 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8153 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8154 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8155 compiler.
8157 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8159 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8160 grep -q isn't portable. Improve grep -s explanation.
8161 Problem reported by Dan Manthey.
8163 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8165 * doc/autoconf.texi (Special Shell Variables): Clarify
8166 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8168 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8170 * doc/autoconf.texi: Use @acronym for DJGPP.
8171 Fix some @code's that should have been @env's, and vice versa.
8172 Sort environment variable names.
8173 Mention that shells no longer inherit IFS.
8174 Don't recommend PATH_SEPARATOR=';' so strongly.
8175 Mention that $RANDOM might expand to the empty string.
8176 "symlink" and "soft link" -> "symbolic link".
8177 Improve mktemp description (reported by Bruno Haible).
8179 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8181 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8182 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8183 Likewise.
8184 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8185 Likewise.
8187 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8189 * NEWS: Mention AT_COPYRIGHT.
8191 * tests/local.at (AT_CMP): Use diff directly on input files rather
8192 than copying them.
8194 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8195 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8197 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8198 and Paul Eggert <eggert@cs.ucla.edu>
8200 * tests/autotest.at (Empty test suite): New test.
8201 * tests/torture.at (Substitute and define special characters)
8202 (Substitute a 2000-byte string, Define to a 2000-byte string)
8203 (Substitute a newline, Define a newline): New tests.
8205 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8207 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8208 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8209 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8210 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8211 (Standard regular expressions): New test.
8212 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8213 excess test name quoting.
8214 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8215 CPPFLAGS to `configure' instead of setting it in `configure'.
8217 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8218 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8219 on some platforms.
8221 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8222 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
8224 * tests/local.at (AT_CMP): New macro.
8225 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
8226 (AC_SAVE_STATE): Move environment grep...
8227 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
8228 (AT_CONFIG_CMP): New macro.
8229 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
8230 * tests/c.at (Extensions): Do not exit early.
8231 * tests/atlocal.in: Inherit $GREP.
8233 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
8234 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
8236 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
8237 (AC_COPYRIGHT): Factor header comment portion out and move into...
8238 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
8239 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
8240 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
8241 --version output.
8242 * tests/local.at: Add Autoconf test suite copyright notice.
8243 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
8245 2005-02-04 Bruno Haible <bruno@clisp.org>
8246 and Paul Eggert <eggert@cs.ucla.edu>
8248 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
8250 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8252 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8253 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8255 Try not to generated lines of unlimited length, as POSIX places a
8256 2047-byte limit on line length of portable text files.
8257 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8258 Use newline as a separator, not space.
8259 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
8260 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
8261 space.
8263 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8265 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
8266 as_func_*. Add test to check whether positional parameters
8267 are restored after function return.
8269 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
8271 * doc/autoconf.texi (Special Shell Variables): Mention _,

8316 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8317 Update the long comment explaining it.
8319 m4_require no longer writes an ``is required by'' line to the
8320 execution stack. It contains only one bit of non-redundant
8321 information: that the macro was required, not called. And even
8322 this bit is useless in most situations: have you ever met a macro
8323 which both calls and requires the same macro?
8325 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8326 (_m4_defun_pro_outer): ... only via this macro, for the outermost

8334 * tests/m4sugar.at (m4_require): Expect output without the
8335 ``is required by'' messages.
8337 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8339 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
8340 rather than x for expr.
8342 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
8343 this is safe.
8344 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
8345 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

8358 support.
8359 * bin/autoheader.in: Pass $force to update_file so that
8360 config.h.in is always recreated when --force.

8366 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
8368 * doc/autoconf.texi (Limitations of Builtins): Clarify that

8371 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
8373 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
8374 Warn about newline stripping in `` and $(). Update Solaris
8375 version to 9.

8379 stripping.
8381 2005-01-19 Stepan Kasal <kasal@ucw.cz>

8401 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
8403 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
8405 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

8428 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
8429 otherwise.
8430 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
8431 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8432 stored in _m4_divert_diversion or _m4_divert_dump.
8433 (m4_divert_pop): When the parameter is given, compare the symbolic
8434 name with the last diversion pushed on the stack. Previously, the
8435 current diversion was compared with the numeric value of the
8436 diversion given as the parameter.
8437 (m4_require): If the macro hasn't been expanded yet, call ...
8438 (_m4_require_call): this new macro.

8471 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

8473 not essential. Reported by Magnus Therning.
8474 * tests/torture.at (autoreconf.): New banner.
8475 (autoreconf and non-AC configure): Rename to `Non-Autoconf
8476 AC_CONFIG_SUBDIRS'.

8524 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
8525 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

8652 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

8720 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
8721 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.

8731 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Check libc before
8732 looking elsewhere for getmntent. Problem reported by Mark D. Baushke.
8733 * doc/autoconf.texi (Particular Functions): Mention new behavior.
8735 2004-12-03 Stepan Kasal <kasal@ucw.cz>
8737 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
8738 out the common code to ...
8739 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
8740 value of the #define--default to 1, iff the macro was called
8741 with exactly one parameter.
8743 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
8745 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8746 "char c = '\200';" rather than "char c = 0x80;" as the
8747 latter doesn't conform to the strict C standard due to
8748 overflow on signed char hosts.
8750 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
8751 to -qlanglvl=ansi. We don't want to disable extensions.
8753 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
8755 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

8803 * doc/autoconf.texi (Autoconf Language): Explain that
8804 ``descriptions'' may not be double quotes.
8805 (Quotation Rule Of Thumb): Likewise.
8806 (Pretty Help Strings): Likewise; remove the wrong comment;
8807 simplify the examples and improve their quoting.
8809 2004-11-13 Stepan Kasal <kasal@ucw.cz>
8811 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
8812 the $1_found variable, don't test whether the file is executable;
8813 Both things are checked ...
8814 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
8815 the former ``test -f''.
8816 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
8818 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

8821 use cp -R instead.
8823 2004-11-10 Derek R. Price <derek@ximbiot.com>
8825 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
8826 limitations. Reorder paragraphs for clarity.
8828 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
8830 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
8831 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
8832 variants", "Unix", and some related minor wording fixups.
8834 (Shellology, Special Shell Variables): Document that the Zsh
8835 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

8847 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
8849 * doc/autoconf.texi (auindex): New macro.
8850 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
8851 Problem reported by Stepan Kasal.
8853 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
8855 Fix problems reported by Andreas Buening in:
8856 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
8857 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
8858 in test makefile.
8859 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
8860 readable; it's not true in OS/2-emx.
8862 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
8864 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
8865 "/usr/include", clear ac_x_includes instead of leaving it as "no"
8866 (trivial change). Problem and patch reported by Andrew Church in:
8867 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
8869 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
8871 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

8874 Also, fix some minor spacing and punctuation bugs.
8876 2004-09-02 Akim Demaille <akim@epita.fr>
8878 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
8879 "case" to restore ordering.
8880 Reported by Stepan Kasal.

8892 Version 2.59b.
8894 * README: Add advice about m4 1.4.2.
8896 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
8897 texinfo.tex for now (done by hand now).
8898 * Makefile.maint (wget_files, cvs_files):
8899 Remove ansi2knr.c; nobody uses it.
8900 (ansi2knr.c-url_prefix): Remove.
8901 (cvs-update): Fix test for failure. I don't know why it ever
8902 worked...
8904 * doc/autoconf.texi: Update URLs, some of which went stale.
8905 Use @uref rather than @href.
8907 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
8908 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
8910 * config/config.guess, config/config.sub, config/elisp-comp,
8911 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
8912 doc/fdl.texi, doc/standards.texi: Sync with master copy.
8914 * NEWS, TODO, configure.ac, bin/autoscan.in,
8915 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
8916 doc/install.texi, lib/Autom4te/Configure_ac.pm,

8920 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
8921 tests/tools.at, tests/torture.at:
8922 Use "file name" rather than "filename" or "path",
8923 to be consistent with the terminology of the GNU coding standards.
8925 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
8927 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
8928 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
8929 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
8930 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
8932 More fixes to support spaces in the name of the build directory.
8933 This isn't a complete fix but it's an improvement.
8935 * bin/autoconf.as (autom4te_options): New var.
8936 Use it instead of appending to AUTOM4TE, so that we can allow
8937 spaces in the build directory's absolute name.
8938 * bin/autoheader.in ($autoconf): Allow spaces in file names.
8939 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
8940 AT_CHECK_NOESCAPE): Likewise.
8941 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
8942 main program): Likewise.
8944 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
8946 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
8947 From Ralf Corsepius in:
8948 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
8950 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
8952 * doc/autoconf.texi (Function Portability): Document isinf and
8953 and isnan. From a suggestion by Kevin Ryde.
8955 * lib/Autom4te/General.pm (END): Return correct exit status even
8956 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
8958 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
8960 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
8961 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
8962 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
8964 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
8966 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
8967 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
8968 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
8969 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
8970 * lib/autom4te.in (Automake-preselections): Preselect
8971 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8973 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8975 * lib/autom4te.in (Automake-preselections): Preselect
8976 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
8977 trace them.
8979 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
8981 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
8982 Tru64.
8983 * doc/autoconf.texi (Shellology): Mention BIN_SH.
8984 Document problem with "`""`" in pdksh POSIX mode.
8986 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
8988 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
8989 with pdksh, too. Problem reported by Patrick Welche via
8990 Gary V. Vaughan.
8991 * doc/autoconf.texi (Shellology): Note that set -o posix is
8992 useful for pkdsh, too.
8994 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
8996 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8997 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8998 Don't fail if ENV or BASH_ENV is readonly.
8999 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9000 etc. are read only. Problem reported by Ludovic Courtes.
9002 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9004 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9005 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9006 (trivial change)
9008 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9010 * doc/autoconf.texi (File System Conventions): Warn about
9011 names like "aux". Problem reported by Eric Blake.
9013 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9014 by zero instead of array size, so that we can use any arithmetic
9015 constant expression (instead of requiring an integer constant
9016 expression). This allows us to test expressions like DBL_MAX <
9017 LDBL_MAX, which didn't conform to the C standard using the old
9018 method.
9019 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9020 now that we can do floating-point tests at compile time.
9022 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9024 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9025 and LDBL_EPSILON, as the resulting expression isn't an
9026 integer constant expression and violates the C standard.
9027 Problem reported by Nelson H. F. Beebe. Also, check
9028 for "L" suffix, and check that long double doesn't have
9029 worse range or precision than double, that mixed-mode
9030 arithmetic doesn't generate a diagnostic, that double
9031 constants fit in long double.
9033 2004-06-03 Kevin Ryde <user42@zip.com.au>
9035 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9036 malloc(0) and realloc(NULL,size).
9038 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9039 Bob Proulx.
9041 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9043 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9044 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9045 by Jim Meyering.
9047 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9049 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9050 can be rewritten using if-then-else. Suggested by Bruno Haible.
9052 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9054 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9055 Problem reported by Stepan Kasal.
9057 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9059 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9060 change). Patch reported by Ralf Wildenhues in
9061 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9063 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9064 function F exists if the compiler and linker let you compile an
9065 expression like (F != 0). Recent versions of GCC optimize away
9066 the reference to F in that case, since every function address must
9067 be nonzero, so the link succeeds even if F does not exist.
9068 Problem reported by Manu in
9069 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9071 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9072 "Unix". Many uses changed.
9073 (Limitations of Builtins): Explain better why the ! command isn't
9074 portable.
9076 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9078 * lib/autom4te.in (Automake-preselections): Preselect
9079 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9081 2004-05-19 Kevin Ryde <user42@zip.com.au>
9083 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9084 referencing AC_FUNC_STRERROR_R.
9086 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9087 note pessimistic assumption when cross compiling.
9089 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9091 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9092 (until 2004) invoked subcommands with sh -e, contra POSIX.
9093 Reported by Kevin Ryde.
9095 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9097 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9098 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9099 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9100 `test -f " /usr/bin/grep"', which _always_ failed.
9101 (AC_PROG_SED): Ditto bogus PATH fix.
9102 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9103 requires that grep correctly supports _multiple_ `-e' options, rather
9104 than stating only that grep should accept `-e'.
9106 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9108 Port to C99, which requires that 'exit' be declared.
9110 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9111 to ensure that stdlib.h is included.
9112 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9113 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9114 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9115 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9116 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9117 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9118 when using 'exit' in a test; C99 requires that 'exit' be declared.
9120 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9122 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9123 now prefers 'grep' implementations that accept -e.
9124 (Limitations of Usual Tools): Describe problems of traditional
9125 egrep and fgrep with long input lines, and of traditional grep
9126 with -e.
9127 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9128 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9129 All callers changed. Append /usr/xpg4/bin to the PATH, for
9130 Solaris.
9131 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9132 the user with complaints about multiple -e options.
9133 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9134 Define it with AC_PROG_GREP.
9135 * configure.ac (AC_PROG_GREP): Add.
9136 * lib/freeze.mk (GREP): New macro.
9138 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9140 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9141 a possible candidate only after all others fail, rather than
9142 consulting it first. This improves backward compatibility by
9143 better reflecting the way shell selection occurred in previous
9144 versions of Autoconf, and should help to avoid triggering latent
9145 problems in other packages, such as the one in Automake where zsh
9146 is not handled robustly:
9147 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9148 Although it is not Autoconf's responsibility to work around
9149 problems in Automake, it nevertheless makes sense to avoid
9150 introducing unnecessary incompatibilites.
9152 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9153 Gary V. Vaughan <gary@gnu.org>
9155 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9156 how deeply nested we are when a suitable tool is found, set the
9157 ac_path_TOOL_found flag.
9158 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9159 nested we are in this macro. Break out of all 3 nested loops if
9160 ac_path_TOOL_found is set.
9162 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9164 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9165 of the _AS_PATH_WALK loop too if GNU flavor is found.
9167 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9169 * doc/autoconf.texi (Limitations of Make): Update documentation
9170 for `$<'. New entry `Long lines', based on a report from Simon
9171 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9172 paragraph about DJGPP, based on a mail from Richard Dawe.
9174 2004-04-20 Paul Eggert <eggert@twinsun.com>
9176 * tests/c.at (C keywords): Don't assume that GCC supports
9177 "restrict" and "inline", as sufficiently-old GCC versions do not
9178 (also, GCC configured to be in pedantic C89 mode does not).
9179 Problem reported by Sumit Pandya in:
9180 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9182 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9183 consider -g to work if it generates warnings when plain compiles
9184 don't. Problem reported by Braden McDaniel in:
9185 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9187 * doc/autoconf.texi (Slashes): New section, to document a problem
9188 reported by Jim Meyering in:

9196 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9198 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9199 best tool so far counter rely on the tool path variable name to
9200 avoid checks for one tool being affected by the results of running
9201 the length check on a previous tool.
9203 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9204 match expression argument, as different greps have different
9205 regular expression flavours.
9206 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9207 literals.
9208 (AC_PROG_EGREP): Pass 'EGREP$'.
9209 (AC_PROG_GREP): Pass 'GREP$'.
9211 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>

9219 Types, Specific Compiler Characteristics, System Services,
9220 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9221 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9222 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9223 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

9236 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9237 now defines HAVE_DECL_TZNAME if it is declared, when
9238 HAVE_STRUCT_TM_TM_ZONE is not defined.
9239 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9240 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9241 for HAVE_TZNAME.
9243 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
9245 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected

9253 H. F. Beebe for the bug report.
9255 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9257 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9258 quoted -cmdline argument in Portland Group compiler (bug
9259 reported by Jeffrey J. Barteet).

9285 AC_CHECK_TOOLS.
9286 (Specifying Names): Document the reason for these future
9287 behavioral changes.
9288 * tests/mktests.sh: Do not generate tests for the
9289 new macros.
9290 * NEWS: Document these changes.
9292 * doc/autoconf.texi: Avoid macros with unbraced arguments,
9293 they make TeX hang up.

9298 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
9299 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
9300 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
9301 vowel.

9311 Problem reported by Anthony N. Frasso in
9312 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
9313 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
9315 2004-02-23 Gary V. Vaughan <gary@gnu.org>

9318 from the next generation of Libtool.
9319 * lib/autom4te.in (Autoreconf-preselections): Ditto.
9321 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9323 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
9324 is not always thread-safe. Report from Nathanael Nerode.
9326 2004-02-18 Paul Eggert <eggert@twinsun.com>
9328 Fix a dependencies problem, stemming from a Autoconf 2.59 build
9329 problem on QNX reported by Stephen Rasku in
9330 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
9332 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
9333 $(m4sh_m4f_dependencies); this removes a FIXME.
9334 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
9335 (MAINTAINERCLEANFILES): Split into pieces,
9336 one per related section. Add $(srcdir)/wrapper.in.
9338 2004-02-09 Paul Eggert <eggert@twinsun.com>
9340 * doc/autoconf.texi (Setting Output Variables): Emphasize that
9341 AC_SUBST provides no portable way to escape literal newlines.
9343 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9344 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9345 Darwin uses -lcrt2.o and there's little point to cataloging all
9346 the system variants. Partial fix reported by Andreas Waechter in:
9347 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
9348 for bug reported by Nelson H. F. Beebe in:

9363 the behavior of the third argument.
9364 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
9365 correctly the behavior of the third argument. Document
9366 what the three macros that AU_DEFUN defines do. Fix
9367 warning message when the third argument includes $0

9370 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9371 Eric Sunshine <sunshine@sunshineco.com>
9372 Paul Eggert <eggert@twinsun.com>
9374 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
9375 (AS_INIT): Output shell initialization there. Removed optional
9376 parameter. Expand _AS_SHELL_FN_SPY.
9377 (AS_INIT_WITH_SHELL_FN): Removed.
9378 (_AS_SHELL_FN_SPY): New macro.
9379 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
9380 macros.
9381 (AS_SHELL_SANITIZE): Remove loop to find better shell
9382 and documentation for the parameter.
9383 (_AS_DETECT_BETTER_SHELL): Move it here.

9386 (AS_REQUIRE_SHELL_FN): Require shell functions when
9387 it is used.
9388 (_AS_LINENO_WORKS): Put around braces, we do not
9389 trigger the bash bug anymore.
9390 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
9391 use AS_INIT_WITH_SHELL_FN.
9392 * bin/autoconf.in, tests/wrapper.in: Regenerated.
9394 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9396 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

9400 (AU_DEFUN): Honor the third parameter, create autoupdate
9401 macros with AU_DEFINE.
9402 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
9403 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

9405 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
9406 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

9422 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9423 2003 (except 1997) to the list of copyright years. This undoes
9424 the 2003-05-22 change, which removed the older years from the list.
9425 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
9427 2004-01-27 Gary V. Vaughan <gary@gnu.org>
9428 Albert Chin-A-Young <china@thewrittenword.com>

9438 _AC_PROG_GREP, and AC_PROG_SED.
9439 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
9440 longest input length accepted by a command.
9441 (AC_PROG_SED): Use it.
9442 * doc/autoconf.texi (Particular Programs): Document the changes.
9443 * NEWS: Updated.
9445 2004-01-27 Paul Eggert <eggert@twinsun.com>

9467 sources.
9469 2004-01-26 Paul Eggert <eggert@twinsun.com>
9471 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9472 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9473 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9474 not <inttypes.h>. Problem reported by Tim Mooney in
9475 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9476 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9477 Likewise.
9479 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9480 otherwise "make check" fails because it forbids cmp (I guess
9481 because cmp treats files as binary on DOS-like systems).
9483 * tests/mktests.sh: Update copyright date to 2004, since some tests
9484 have changed in 2004.
9486 2004-01-23 Gary V. Vaughan <gary@gnu.org>
9488 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
9489 non-truncating sed or gsed program in PATH.
9490 * tests/acprograms.at: Add it.
9491 * doc/autoconf.texi (Particular Programs): Document it.
9492 * NEWS: Updated.
9494 2004-01-15 Paul Eggert <eggert@twinsun.com>
9496 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9497 -std1 disables some useful extensions on Tru64. Problem reported
9498 by N. Lichtmaier in
9499 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
9501 2004-01-14 Paul Eggert <eggert@twinsun.com>
9503 * doc/autoconf.texi (Programming in M4sh): Document that
9504 AS_MKDIR_P succeeds if the destination is a symbolic link
9505 to an existing directory.
9506 (Limitations of Usual Tools): Note that mkdir -p might not
9507 succeed on symlinks to directories.
9509 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9511 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
9512 * bin/autoheader.in: Grammar fix in message.
9513 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
9514 Test for dir before calling mkdir -p. (trivial changes)
9516 2004-01-13 Eric Blake <ebb9@byu.net>
9518 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
9519 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
9521 2004-01-10 Jim Meyering <jim@meyering.net>
9523 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
9525 2004-01-09 Paul Eggert <eggert@twinsun.com>
9527 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9528 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9529 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9530 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9531 AC_COMPILE_IFELSE, since we now assume our caller invokes
9532 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9533 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9534 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9535 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9537 2004-01-07 Paul Eggert <eggert@twinsun.com>
9539 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9540 `"'...'"`, as it's confusing (and I suspect it may not work on
9541 some platforms). The code was incorrect anyway, as it assumed
9542 that \$ evaluated to itself in that context. Reported by
9543 Alexandre Duret-Lutz.
9545 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9547 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
9548 and _LT_AC_TAGCONFIG.
9550 2004-01-06 Paul Eggert <eggert@twinsun.com>
9552 * doc/autoconf.texi (One Macro Call): Fix an incorrect
9553 example, and add more examples. Reported by Eric Sunshine.
9555 2004-01-05 Paul Eggert <eggert@twinsun.com>
9557 * doc/autoconf.texi (Limitations of Usual Tools):
9558 Remove warning against "rm -fr" introduced yesterday; it
9559 was a false alarm.
9561 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
9562 autoscan, autoupdate, ifnames): Don't use chmod -w.
9563 * lib/Makefile.am (autom4te.cfg): Likewise.
9564 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
9565 "chmod -w".

9568 Paolo Bonzini <bonzini@gnu.org>
9570 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
9571 by doing lineno substitution only on lines containing "$LINENO".
9573 2004-01-04 Paul Eggert <eggert@twinsun.com>
9575 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
9576 Use "rm -f" to remove conftest.sed, not plain "rm".
9577 Bug reported by David Relson in
9578 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9580 * Makefile.am (autom4te-update):
9581 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
9582 * Makefile.maint (my-distcheck, do-po-update): Likewise.
9583 * doc/autoconf.texi (Guidelines): Likewise.

9591 srcdir): Likewise.
9592 * doc/autoconf.texi (Limitations of Usual Tools):
9593 Warn against "rm -fr".
9595 2004-01-03 Paul Eggert <eggert@twinsun.com>
9597 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9598 -c -o might not work. From a suggestion by Kevin Ryde.
9599 (C Compiler, Generating Sources, Limitations
9600 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9601 Don't put '-o' after non-options, as POSIX doesn't allow this.
9602 Mention that cc's name might be gcc or c89 or whatever.
9604 2004-01-04 Kevin Ryde <user42@zip.com.au>
9606 * doc/autoconf.texi: Add various further index entries.
9608 2003-12-29 Paul Eggert <eggert@twinsun.com>
9610 * bin/autoreconf.in (autoreconf_current_directory):
9611 Fix typo: mkdir without umask arg.
9613 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9615 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9616 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

9670 (&sizes): New.
9671 Use them.
9672 No longer rely on Gnus to inline the list of signatures: compute
9673 them on the fly.
9675 2003-11-24 Akim Demaille <akim@epita.fr>
9677 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
9678 override some files.
9679 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
9680 From Debian Autoconf 2.58.

9746 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

9882 cross test.
9884 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
9886 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
9887 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

9899 Problems reported by Eric Sunshine.
9901 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
9903 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
9904 -mGLOB_options_string stuff for Intel ifc, which can cause
9905 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
9906 pattern-matching instead of grep.

9928 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
9929 cache variable instead of $G77 to decide whether to include -O2,
9930 since $G77 is specific to Fortran 77.

9934 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

9937 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9939 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
9940 arguments so that it can be used with syntax identical to
9941 AC_PROG_F77, and so that we can more easily decide to
9942 remove/deprecate the DIALECT optional argument in the future if it
9943 proves troublesome.
9944 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
9945 non-freeform-supporting compilers. Document freeform flags.

9949 * configure.ac: Look for emacs, not macs.
9950 Reported by Eric Sunshine.
9952 2003-10-03 Akim Demaille <akim@epita.fr>
9954 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
9955 * bin/autoreconf.in (autoreconf_current_directory): Create the

9959 2003-10-03 Akim Demaille <akim@epita.fr>
9961 * configure.ac: Quotation and formatting changes.

9984 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.

10010 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10011 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10012 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10014 2003-09-26 Akim Demaille <akim@epita.fr>
10016 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10017 directory for AC_CONFIG_COMMANDS' first argument exists.
10018 This makes valid the invocation of _AC_SRCPATH that follows.
10019 Reported by Eric Sunshine.
10020 * doc/autoconf.texi (Configuration Commands): Adjust.
10022 2003-09-26 Akim Demaille <akim@epita.fr>
10024 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
10025 Reported by Ralf Corsepius.
10027 2003-09-26 Akim Demaille <akim@epita.fr>
10029 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
10030 arguments.

10043 The test suite are sometimes assigning timings incorrectly.
10044 Reported by Henk Krus.
10045 Diagnosed by Nicolas Joly.
10047 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10048 AT_help_all.
10049 Instead of making AT_help a sequence of assignments to grow
10050 $at_help_all, just make AT_help_all be the growing contents of
10051 $at_help_all, and make a single assignment in...
10052 (AT_INIT): here.
10053 (at_times_skip): Flip the meaning and rename as...
10054 (at_times_p): this.
10055 (AT_INIT): When summarizing the test that ran, remove
10056 $at_times_file after use, and check it is present before trying to
10057 use it.

10065 (ifnames): chmod -w.
10066 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10067 executables, not bin/ executables! Otherwise all the magic needed
10068 to find non installed files is turned off. This caused a failure
10069 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10070 as found in its environment (sent by tests/autoreconf): pointing
10071 to bin/autom4te that could not find its files.
10072 * tests/mktests.sh: Force the replacement of generated files, for
10073 the sake of "mv" program that are interactive when overwriting a
10074 -w file.
10075 * config/install-sh: Upgrade from CVS Automake.
10077 2003-09-23 Paul Eggert <eggert@twinsun.com>

10085 Trivial change to support GCC's configuration procedure.
10086 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
10087 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
10088 about inconsistency if the preprocessor is set to give errors for
10089 any warning.

10144 Improve the accuracy of the wording about obsolescence.
10145 From a suggestion by Ian Lance Taylor in
10146 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
10148 2003-09-05 Paul Eggert <eggert@twinsun.com>
10150 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,

10166 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10168 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10170 Add support for newer Fortran dialects. The F77 interface is
10171 unchanged, and continues to support Fortran 77. New FC macros
10172 correspond to all the old F77 macros, with output variables FC,
10173 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10174 available dialect, but older dialects can be specified. There are
10175 new macros AC_FC_SRCEXT to set the source extension, and
10176 AC_FC_FREEFORM to accept free-form source files.

10206 Document problems with timestamp resolution that 'make', 'cp -p', and
10207 'touch -r' have.
10209 2003-08-27 Akim Demaille <akim@epita.fr>
10211 * tests/m4sugar.at (cross_warning): Make sure to enable the
10212 output, so that we can track spurious m4sugar output.
10213 * tests/local.at: Require 2.57.
10214 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10215 are defaulted by AT_CHECK anyway.

10217 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
10218 missing dnl.

10269 2003-08-22 Akim Demaille <akim@epita.fr>
10271 Output stack traces in warnings.
10273 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
10274 Replace the former...
10275 (m4_warn): Pass the call stack to _m4_warn.
10276 * bin/autom4te.in: Adjust to output the call stack.
10277 * tests/m4sugar.at (m4@&t@_warn): Adjust.
10279 2003-08-22 Akim Demaille <akim@epita.fr>

10286 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
10287 (&verbose): Remove.
10288 (&getopt): Adjust the note and verb channels, depending upon

10292 Use &verb, not &verbose.
10294 2003-08-21 Akim Demaille <akim@epita.fr>
10296 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10297 &parse_WARNINGS.
10298 ($help): Use Autom4te::ChannelDefs::usage.
10299 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10300 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10302 2003-08-21 Akim Demaille <akim@epita.fr>
10304 First stab at preserving warnings between calls to autom4te,
10305 including when the cache is used.
10307 There are still several issues: (i) there are too many runs of m4
10308 (one for include, one for warnings, and some more), (ii) warnings
10309 spreading on several lines are not handled gracefully, (iii) the
10310 code meant to have the call stack display for errors does not work
10311 (its handling should move from m4 to autom4te).
10313 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10314 Use them.
10315 (@preselect): Add m4_warn.
10316 ($exit_status): Remove, use $exit_code.
10317 ($help): Use Autom4te::ChannelDefs::usage.
10318 (&handle_m4): No longer define the m4_warnings.
10319 At each run, extract and report the warnings.
10320 Always cache the result, including if the exit status is on
10321 failure, since if nothing changes, we should result in the same
10322 failure, hence we can use the cache.
10323 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10324 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10325 Remove.
10326 (m4_warn): Redefine as a do-nothing: it is its invocation that
10327 matters, as warnings are now reported via traces.
10328 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10329 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10330 the latter reveals calls to the former.
10332 Adjust the tests.
10334 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10336 2003-08-21 Akim Demaille <akim@epita.fr>
10338 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
10339 Use them.
10341 2003-08-21 Akim Demaille <akim@epita.fr>
10343 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
10344 forward order.
10345 * lib/Autom4te/ChannelDefs.pm: Doc typos.
10346 (&parse_warnings): Accept a list of warning requests.
10347 (&usage): Return a string, not a side effect.
10348 (cross): New warning category.
10350 2003-08-21 Akim Demaille <akim@epita.fr>
10352 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
10353 (&require_configure_ac): Accept an optional directory argument.
10354 ($configure_ac): Remove.
10355 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10356 (&catfile): Remove.
10357 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10358 * bin/autoscan.in: Adjust.
10360 2003-08-20 Akim Demaille <akim@epita.fr>
10362 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
10363 Reported by Alexandre Duret-Lutz.
10365 2003-08-20 Akim Demaille <akim@epita.fr>
10367 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10368 * bin/autom4te: Adjust.
10369 In particular, be Autoconf tools are really silent when properly
10370 working, bind the verbosity of the 'note' channel to $verbose.
10371 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10372 (&xsystem, &contents): Remove, since they are exported by...
10373 * lib/Autom4te/FileUtils.pm: this.
10374 More perldoc.
10375 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10376 * lib/Autom4te/FileUtils.pm: here.
10378 2003-08-20 Akim Demaille <akim@epita.fr>
10380 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
10381 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
10382 from CVS Automake.
10384 2003-08-20 Akim Demaille <akim@epita.fr>
10386 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
10387 (autom4te-update): New.
10388 * Makefile.cfg (update): Bind autom4te-update.
10390 2003-08-19 Derek Price <derek@ximbiot.com>
10392 * lib/autotest/general.m4: Comment various HELP_* diversions.

10396 package specific options and associated help.
10398 2003-08-19 Akim Demaille <akim@epita.fr>

10404 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>

10408 and m4_sinclude.
10410 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
10412 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...

10414 * doc/autoconf.texi (autom4te Invocation): Mention
10415 Autoconf-without-aclocal-m4.
10417 2003-08-18 Derek Price <derek@ximbiot.com>
10419 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
10420 RUN-IF-PASS optional arguments.

10429 STDOUT & STDERR arguments.
10431 2003-08-14 Derek Price <derek@ximbiot.com>
10433 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
10434 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
10435 shorter column three. Add DESCRIPTION to log file content.
10437 2003-08-13 Derek Price <derek@ximbiot.com>
10439 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
10440 output.

10444 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
10445 (AT_CHECK_NOESCAPE): Move core functionality to...
10446 (_AT_CHECK): ...this new macro.
10448 2003-08-07 Derek Price <derek@ximbiot.com>
10450 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
10451 (AT_CHECK_NOESCAPE): ...to this new macro.
10453 2003-07-31 Paul Eggert <eggert@twinsun.com>
10455 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
10456 in Bash 2.01. Problem reported by Brian Gough in
10457 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
10459 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
10461 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
10462 -lcrt1.o, for OS X. (trivial change)
10464 2003-07-07 Paul Eggert <eggert@twinsun.com>
10466 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
10467 inside '#ifndef __cplusplus'. Problem reported by
10468 Bob Friesenhahn.
10470 2003-07-06 Bill Clarke <llib@computer.org>
10472 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10473 'long', not 'int', for benefit of Sun's recent C++ compilers
10474 (trivial change). See:
10475 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
10476 (This really should be 'intptr_t', not 'long', but that would
10477 take more work.)
10479 2003-06-25 Akim Demaille <akim@epita.fr>
10481 * lib/Makefile.am (autom4te.cfg): Make it read only.
10482 Depend on Makefile since it contains substitutions.
10483 From Paolo Bonzini.
10484 * lib/autom4te.in (args): Add local.at? for Autotest args.
10485 This change was made on autom4te.cfg which is generated.

10491 From Gareth McCaughan.
10493 2003-06-23 Akim Demaille <akim@epita.fr>
10495 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10496 not all of them. This fixes 1. the fact that when testing
10497 Autoconf there are many many config.log, 2. the incorrect use of
10498 top_srcdir to find config.log.
10499 Don't mix the detailed output of failed test with the summary of
10500 failures. Rather, append detailed log afterwards.
10502 2003-06-23 Akim Demaille <akim@epita.fr>
10504 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

10509 * tests/torture.at (#define header templates): Don't use quotes in
10510 C++ comments as it puzzles Emacs' sh font-lock-mode.

10525 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
10526 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
10527 ensuring we add -std1 for full-ANSI.
10529 * doc/autoconf.texi (hdrindex): New macro.
10530 Add index entries for portability of various standard header files.
10532 2003-06-20 Akim Demaille <akim@epita.fr>

10558 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
10559 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.

10567 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
10568 changes.
10569 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
10570 Autoconf nor Automake.
10571 (&contents): New, from Automake.
10572 PODify.
10574 2003-05-28 Paul Eggert <eggert@twinsun.com>
10576 * NEWS, doc/autoconf.texi (Particular Functions),
10577 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
10578 is the inverse of localtime.
10580 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
10582 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10583 (handle_exec_errors): New function. Work around $! being
10584 altered by WEXITSTATUS.
10585 (xqx, xsystem): Use handle_exec_errors.
10587 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10589 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10590 Do not call `_exit()', simply modify `$?'.
10591 (xsystem): Reset $! before running system, and check it afterward.
10592 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10593 63 for version mismatches.
10595 2003-05-23 Akim Demaille <akim@epita.fr>
10597 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10598 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10599 the middle of a line).
10600 * lib/m4sugar/m4sugar.m4: Likewise.
10601 Remove useless spaces in comments.
10603 2003-05-23 Akim Demaille <akim@epita.fr>
10605 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10606 exit 63, so that we (or Automake's "missing") can tell the
10607 difference with a plain failure.
10608 * doc/autoconf.texi (Notices): Adjust.
10610 2003-05-23 Akim Demaille <akim@epita.fr>
10612 * Makefile.am, bin/Makefile.am, config/Makefile.am,
10613 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
10614 White spaces cleanup.
10616 2003-05-22 Jim Meyering <jim@meyering.net>
10617 Paul Eggert <eggert@twinsun.com>
10619 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10620 Remove `#include <stdlib.h>' from the list; we should never
10621 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10622 resulting namespace pollution would cause other tests to fail.
10623 Configure scripts run with some older versions of g++ and HP's
10624 aCC would fail due to such an #include. Problems reported by
10625 Matthew Mueller in <http://bugs.debian.org/120704> and by
10626 Keith Bostic in
10627 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10628 In the test, use the test declaration before including <stdlib.h>,
10629 as that's closer to how it'll be used.
10631 2003-05-23 Akim Demaille <akim@epita.fr>
10633 * doc/autoconf.texi (Header Portability): ucred.h.
10634 From Ian Redfern.
10636 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10638 Overhaul Autotest's logging: generate separate log files
10639 in testsuite.dir/NNN/testsuite.log, and append them to
10640 testsuite.log instead of re-running the test verbosely.
10642 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10643 file descriptor, write 0 to at_status_file instead of setting
10644 at_status=0, initialize some new variables (at_status_file,
10645 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10646 to rerun the tests, instead append the at_group_log to the
10647 at_suite_log when a test fails.
10648 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10649 with the AS_MESSAGE_LOG_FD redirected to stdout.
10650 (AT_CLEANUP): save the output status in $at_status_file
10651 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10652 its original place.
10653 (AT_CHECK): since tests are run with a redirected stdout,
10654 and used to be re-run in verbose mode, turn some $at_verbose
10655 into echo, and don't redirect the output of testing stdout
10656 and stderr.
10658 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10659 the name of the debugging directory and information about
10660 its contents.
10662 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10664 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
10665 parameter.

10687 Whitespace clean up.
10688 Suggested by Jim Meyering.
10690 2003-05-22 Akim Demaille <akim@epita.fr>
10692 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
10693 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
10694 Reported by Jim Meyering.
10696 2003-05-22 Akim Demaille <akim@epita.fr>
10698 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

10729 AC_CHECK_HEADERS_NEW): New tests.
10731 2003-05-17 Akim Demaille <akim@epita.fr>
10733 * lib/autoconf/functions.m4: Use the default includes so that
10734 memcmp be declared before being tested.
10735 Reported by Sander Niemeijer.
10736 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

10754 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10755 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
10756 them uniform, and more robust to Perl special characters.
10757 Reported by Martin Mokrejs.
10759 2003-05-14 Akim Demaille <akim@epita.fr>

10779 2003-05-06 Akim Demaille <akim@epita.fr>
10781 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10782 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10783 by aclocal.m4 is changed it might require the importing of another
10784 m4 extension file, i.e., aclocal must be run.
10786 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10787 (&parse_args): Use --force with aclocal if required and supported.
10788 (&autoreconf_current_directory): Use &run_aclocal.

10795 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
10796 argument instead of a file name, so that the request file remains
10797 open during the whole autom4te run.
10798 ($icache_file): New.
10799 (&freeze): Lock the $icache_file.
10801 2003-04-29 Derek Price <derek@ximbiot.com>
10803 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10804 seperator with m4_append_uniq(). It doesn't work.
10805 (AT_CLEANUP): Add `;' to end of at_help_all.
10806 (AT_INIT): Allow --keywords to be specified more than once. When
10807 grepping $at_help_all for keywords, use the field and keyword
10808 seperators to ensure a complete keyword match. Alter at_prev handling
10809 to support the new --keywords behavior.
10811 2003-04-27 Karl Berry <karl@freefriends.org>
10813 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10814 align better with others. I also made some of the individual
10815 entries on one line, for brevity and to make it easier for me to
10816 sort my dir-example file in the Texinfo distribution :).

10857 Use them.
10858 * doc/Makefile.am (CLEANFILES): Adjust.
10859 (TEXI2DVI): Make it --batch.
10861 2003-03-31 Derek Price <derek@ximbiot.com>
10863 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
10864 which removed the main loop.
10865 Thanks to Akim Demaille.
10867 2003-03-29 Akim Demaille <akim@epita.fr>

10883 header causes problems.
10885 2003-03-28 Akim Demaille <akim@epita.fr>
10887 * tests/torture.at (Configuring subdirectories): Require aclocal
10888 1.4, otherwise the test fails, as it does support configure.ac.

10891 2003-03-28 Akim Demaille <akim@epita.fr>
10893 * doc/autoconf.texi (C Compiler): `#line' portability.

10959 about `$<' in inference rules, it was a bogus interpretation of
10960 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
10961 Tru64 make in the "target lookup" section.
10962 (Automake): Automake 1.5+ no longer requires special tools to be
10963 present on the developer's host.
10965 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>

11004 to fix a mismatch between example and discussion.
11006 2003-02-24 Kevin Ryde <user42@zip.com.au>
11008 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf

11016 2003-02-20 Akim Demaille <akim@epita.fr>
11018 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
11019 compiler says yeah, but preproc says nope, compiler is right.
11020 Conversely, prompt the reader to send a bug report to the
11021 maintainers of the package, not of Autoconf.
11023 2003-02-20 Klee Dienes <kdienes@apple.com>
11025 * bin/autoreconf.in (autoreconf_current_directory): Properly

11034 2002-12-23 Paul Eggert <eggert@twinsun.com>
11036 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11037 innocuous variant befor including <limits.h> or <assert.h>. This
11038 works around a bug reported by Albert Chin: HP-UX 11i
11039 (and earlier versions) have a <limits.h> that declares
11040 gettimeofday and many other functions.
11042 2002-12-03 Paul Eggert <eggert@twinsun.com>
11044 Version 2.57.
11046 * NEWS, configure.ac: Update version.
11048 * doc/fdl.texi: Upgrade to FDL version 1.2.
11050 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11051 nontrivially in main's body, so that f's external declaration is
11052 not optimized away in AIX. This should fix the bug reported by
11053 Martin Frydl in
11054 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11056 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11057 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11058 defined, to support freestanding compilers. This should fix the
11059 bug reported by Momchil Velkov in
11060 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11062 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11063 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
11064 obsolete AC_CHECK_TYPE. The missing empty arg was reported
11065 by Simon Josefsson in
11066 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
11068 * Makefile.maint (www-gnu): New macro.
11069 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
11070 the location has moved.
11072 2002-12-02 Martin Frydl <martin@systinet.com>
11074 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
11075 \(.*\) match is too long and there is something more to be checked.
11076 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
11078 2002-11-15 Akim Demaille <akim@epita.fr>
11080 Version 2.56.
11082 * config/install-sh: chmod +x.
11083 From Paul Eggert.
11084 * config/move-if-change: Indenting changes.
11085 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
11086 * configure.ac (AM_INIT_AUTOMAKE): here.
11087 Require 1.7.1.
11089 2002-11-14 Akim Demaille <akim@epita.fr>
11091 Version 2.55.
11093 * config/config.guess, config/config.sub, config/install-sh:
11094 Update from masters.
11096 2002-11-14 Akim Demaille <akim@epita.fr>
11098 * Makefile.maint: Sync with Bison, i.e.:
11099 (po-check): Scan .l and .y files instead of the
11100 .c and the .h files that they generate. This fixes the bug
11101 reported by Tim Van Holder in:
11102 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11103 Look for N_ as well as for _. Try to avoid matching #define for
11104 N_ and _.
11105 From Paul Eggert.
11107 2002-11-14 Akim Demaille <akim@epita.fr>
11109 * doc/autoconf.texi (C Compiler): Compiling several files at once.
11110 From Paul Eggert and Albert Chin-A-Young.
11112 2002-11-14 Akim Demaille <akim@epita.fr>
11114 * doc/autoconf.texi (C Compiler): Solitary backslashes.
11115 From Paul Eggert and Albert Chin-A-Young.
11117 2002-11-14 Kevin Ryde <user42@zip.com.au>
11119 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11120 than assigning in main, to avoid HP cc +O3 optimizing it away.
11122 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11124 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11125 option. Process --recheck after parsing all options. Pass -q
11126 option to configure on --recheck.
11127 (AC_OUTPUT): Pass -q from configure to config.status.
11128 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11129 arguments to record.
11130 * doc/autoconf.texi (config.status Invocation): Document
11131 config.status -q option.
11133 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11135 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11136 Makefile.in if Makefile.am exists.
11137 (output): Strip `.am' from Makefiles. Don't
11138 output AC_CONFIG_FILES if no Makefiles were found.

11149 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
11150 declaration in extern "C" too.
11151 Reported by Roberto Bagnara.
11153 2002-11-06 Akim Demaille <akim@epita.fr>
11155 * tests/torture.at (Configuring subdirectories): Don't use grep
11156 -w.

11158 Reported by Ezra Peisach.
11160 2002-11-05 Akim Demaille <akim@epita.fr>
11162 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11163 Remove.
11164 We _have_ to stop using the old compatibility scheme that tried to
11165 avoid useless backslashes because Libtool 1.4.3 contains a
11166 AC_DEFINE([error_t], [int],
11167 [Define to a type to use for \`error_t' if it is not
11168 otherwise available.])
11169 We _have_ to quote the single quote and backslashes with \. The
11170 old compatibility scheme saw that ` was backslashed, and therefore
11171 did not quote the single quote. Hence before this patch, Autoconf
11172 was not compatible with Libtool.
11174 2002-11-04 Paul Eggert <eggert@twinsun.com>
11176 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
11177 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
11178 LC_NAME, LC_PAPER, LC_TELEPHONE.

11181 2002-11-04 Akim Demaille <akim@epita.fr>
11183 Version 2.54c.
11185 * Makefile.maint (update, cvs-update, po-update, do-po-update):
11186 New.
11187 * config/texinfo.tex: Update.
11189 2002-11-03 Akim Demaille <akim@epita.fr>
11191 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
11192 from...
11193 (&autoreconf): here.
11194 ($help, $make, &parse_args, &autoreconf_current_directory):
11195 Support -m/--make.
11196 * doc/autoconf.texi (autoreconf Invocation): Adjust.

11211 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
11212 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
11214 2002-10-31 Akim Demaille <akim@epita.fr>
11216 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
11217 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
11218 Make variable, not a shell variable.
11219 Suggested by Bruno Haible.
11221 2002-10-31 Akim Demaille <akim@epita.fr>
11223 * bin/autom4te.in (load_configuration): Reject #args out of any
11224 language.
11226 2002-10-31 Akim Demaille <akim@epita.fr>

11242 2002-10-29 Paul Eggert <eggert@twinsun.com>
11244 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
11245 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
11246 Problem reported by Bruno Haible.
11248 2002-10-29 Akim Demaille <akim@epita.fr>
11250 * doc/autoconf.texi (Header Templates): Put also in words what the
11251 pictures says to assist free style readers.

11511 strings.
11513 2002-10-22 Akim Demaille <akim@epita.fr>
11515 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
11516 characters is a syntax warning now.
11517 (_AS_QUOTE): Accept $2 as list of characters to quote.
11518 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
11519 Quote for Perl, not sh.
11520 * bin/autoheader.in: When $debug, report the file which is
11521 `do'ne.
11522 * tests/tools.at (autom4te, autoheader): Exercise @bar, not merely
11523 `@', to tickle Perl's lists.
11524 Reported by Carlos Velasco.
11526 2002-10-18 Akim Demaille <akim@epita.fr>
11528 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that
11529 missing included files _are_ errors.
11530 Thanks to Alexandre Duret-Lutz.
11531 * tests/tools.at (autom4te cache): Adjust.
11532 * tests/atspecific.m4 (AT_CHECK_AUTOM4TE): New.

11538 2002-10-17 Akim Demaille <akim@epita.fr>
11540 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
11541 Fixes the `AC_ARG_VAR' test failures.
11542 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
11543 * lib/freeze.mk (check-forbidden-patterns): New.
11544 * lib/autoconf/Makefile.am, lib/autotest/Makefile.am
11545 * lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
11546 * doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
11547 /dev/null.
11548 Reported months ago by H. Merijn Brand.
11550 2002-10-17 Akim Demaille <akim@epita.fr>
11552 * tests/tools.at (autoheader): Put randoms `@' to stress Perl.
11554 2002-10-16 Paul Eggert <eggert@twinsun.com>
11556 * Makefile.maint (wget_files): Remove ansi2knr.c.
11557 (ansi2knr.c-url_prefix): Remove.
11559 2002-10-16 Akim Demaille <akim@epita.fr>
11561 Because of caching, some files that no longer exist and are no
11562 longer required can still cause errors.
11563 Reported by Alexandre Duret-Lutz.
11565 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
11566 to frozen files in @ARGV, as @ARGV must remain being a list of
11567 files. Rather, at M4 call sites, use this...
11568 (&files_to_options): New function.
11569 (&freeze): Use &error.
11570 (&up_to_date): If a file that was included according to the cache
11571 is no longer there, then the output is out dated.
11572 (&main): Don't even check whether a file is up to date is anyway
11573 --force is given.
11574 * tests/tools.at (autom4te cache): New.
11576 2002-10-16 Akim Demaille <akim@epita.fr>
11578 * bin/autoconf.as: Kill dead options.
11579 * bin/autoupdate.in (&parse_args): Kill old options.
11580 * bin/autoreconf.in (&parse_args): Remove dead options.
11581 Factor some code.
11582 (&autoreconf): Report the directories we enter *and leave*, so
11583 that error messages can be easily located, and use GNU Make
11584 format, so that Emacs' compile mode understands us.
11585 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11586 if some file was changed instead of `print'.
11587 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
11588 (&parse_args): Remove the dead options.
11589 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
11590 autoheader's quiet mode.
11591 (AT_CHECK_AUTOUPDATE): Likewise.
11592 * tests/tools.at (autoupdate): Adjust.

11595 2002-10-11 Akim Demaille <akim@epita.fr>
11597 No longer use CPP to check for the existing of headers: use CC to
11598 check for compilability.
11600 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
11601 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
11602 (_AC_CHECK_HEADER_NEW): Rename as...
11603 (AC_CHECK_HEADER): this.
11605 * lib/autotest/general.m4 (AT_INIT): Include the failed test
11606 numbers in the Subject suggestion.
11608 2002-10-11 Akim Demaille <akim@epita.fr>
11610 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
11611 Suggest using AC_CHECK_DECLS instead.
11613 2002-10-11 Akim Demaille <akim@epita.fr>
11615 * tests/torture.at (AC_ARG_VAR): Have configure report the value
11616 of `precious'.
11618 2002-10-11 Akim Demaille <akim@epita.fr>
11620 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
11621 file name to enable parallel executions.
11622 From Sam Varshavchik.
11624 2002-10-08 Akim Demaille <akim@epita.fr>
11626 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11627 aclocal invocation, as Gettext macros might not be visible to
11628 aclocal.
11629 Instead of blindly running autopoint, scan configure.ac (not the
11630 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11631 Reported by Paul D. Smith.
11633 2002-10-08 Paul Eggert <eggert@twinsun.com>
11635 Work around problems found when POSIXLY_CORRECT=1 is set.
11636 None of this seems to have anything to do with POSIX, really,
11637 but it's how Perl getopt works.
11638 * bin/autom4te.in (parse_args): Configure GetOpt with
11639 "permute", too.
11640 * doc/autoconf.texi (Invoking autom4te):
11641 --warning -> --warnings.
11642 * lib/autom4te.in: --warning -> --warnings.
11644 2002-09-28 Akim Demaille <akim@epita.fr>
11646 * doc/autoconf.texi (autom4te.cache): New section.

11659 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
11661 2002-09-28 Akim Demaille <akim@epita.fr>
11663 * tests/torture.at (Configuring subdirectories): Be robust to
11664 users who use config.site to require for a cache: in this case,
11665 the two last configure runs, using two different sets of
11666 arguments, trigger a legitimate error.
11668 2002-09-28 Akim Demaille <akim@epita.fr>
11670 * tests/m4sh.at (Functions Support, Functions and return Support):
11671 New.

11678 (autom4te): Specify that the sources are in the $srcdir.
11679 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11681 2002-09-28 Akim Demaille <akim@epita.fr>
11683 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
11684 (tm_zone): Move their rules to...
11685 * lib/autoconf/types.m4: here, using AN_ macros.
11686 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11687 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11688 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
11689 * lib/autoconf/programs.m4: here.

11692 Use it.

11696 * lib/autoconf/autoscan.m4: New file.
11697 * lib/autoconf/autoconf.m4: Include it.
11698 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
11699 that were listed in the original autoscan.list.
11700 * lib/autoconf/headers.m4: Similarly with headers.
11701 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11702 (.m4.m4f): Don't pass --prepend-include, since that's done by
11703 tests/autom4te itself.
11704 * lib/autoscan/Makefile.am: Include freeze.mk.
11705 (autoscan.list): New target --this file is no longer a source.
11706 (autoscan.pre): New file.
11708 2002-09-28 Akim Demaille <akim@epita.fr>
11710 * bin/autoscan.in (@kinds): Make them singular.
11711 Adjust all uses.
11712 (&init_tables): When --debug, report the list of rules to ease
11713 tracking changes in autoscan.list.
11714 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11716 2002-09-28 Akim Demaille <akim@epita.fr>
11718 * lib/autoscan/functions, lib/autoscan/headers,
11719 * lib/autoscan/identifiers, lib/autoscan/makevars,
11720 * lib/autoscan/programs: Merge into...
11721 * lib/autoscan/autoscan.list: this.
11722 * bin/autoscan.in (&init_tables): Adjust.
11724 2002-09-28 Akim Demaille <akim@epita.fr>
11726 * lib/autoscan/functions, lib/autoscan/headers,
11727 * lib/autoscan/identifiers, lib/autoscan/makevars,
11728 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11729 `functions' line is now prefixed with `function:'.
11730 * bin/autoscan.in (&init_tables): Adjust.
11732 2002-09-28 Akim Demaille <akim@epita.fr>
11734 From now on, autoscan files must always map a macro name to a
11735 word: there is no `default' macro for autoscan.
11737 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11738 all.
11739 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11740 explicit.
11742 2002-09-28 Akim Demaille <akim@epita.fr>
11744 * bin/autoscan.in (%c_keywords): Remove.
11745 (&used): Keep only track of the words we might be interested in.
11746 (&output_kind): It is no longer needed to look for non active
11747 checks.
11749 2002-09-27 Akim Demaille <akim@epita.fr>

11769 (&parse_args): Drop obsolete undocumented options.
11770 (&output_kind): Output warnings.
11771 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
11772 (getwd): Trigger a warning.
11774 2002-09-26 Akim Demaille <akim@epita.fr>
11776 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
11777 Reported by Ralf Corsepius.

11786 Separated Dependencies'.
11787 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11788 (ifnames, autoscan, autom4te): Un-factor into several rules.
11790 2002-09-25 Paul Eggert <eggert@twinsun.com>
11792 * BUGS (Interoperability bugs): New section. Mention libtool
11793 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
11795 2002-09-24 Paul Eggert <eggert@twinsun.com>
11797 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
11798 make handles suffix-rules differently from GNU make.
11800 * bin/Makefile.am (SUFFIXES, .in): Remove.
11801 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):

11810 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
11812 2002-09-13 Paul Eggert <eggert@twinsun.com>
11814 * doc/autoconf.texi (Particular Headers): Remove obsolete
11815 reference to `struct timezone' in the description of
11816 AC_HEADER_TIME.
11818 2002-09-13 Akim Demaille <akim@epita.fr>
11820 Version 2.54.

11823 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
11824 * Makefile.am: Adjust.
11826 2002-09-13 Akim Demaille <akim@epita.fr>
11828 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
11829 reading config.log when the compiler is rejected.
11830 Suggested by Guido Draheim.
11832 2002-09-13 Akim Demaille <akim@epita.fr>
11834 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11835 (chdir_init) might hang when stat'ing mounted directories.
11836 Reported by Vance Shipley.
11838 2002-09-12 Akim Demaille <akim@epita.fr>
11840 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
11841 the lists.
11843 2002-09-12 Akim Demaille <akim@epita.fr>
11845 * doc/autoconf.texi (Defining Symbols): Present two different
11846 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
11847 difference between 1 argument calls, and 2-3 argument calls.

11851 * doc/autoconf.texi: Review grammar and punctuation.

11856 grammatical typos.
11857 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
11858 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
11859 is obsolescent.
11861 2002-09-11 Akim Demaille <akim@epita.fr>
11863 * doc/autoconf.texi (Questions): Rename as...
11864 (FAQ): this.

11879 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11880 `duplicates', since the algorithm was too naive and could keep
11881 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11882 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11883 Reported by Ralf Corsepius.
11884 * tests/torture.at (Configuring subdirectories): Exercise these
11885 cases.
11887 2002-09-09 Akim Demaille <akim@epita.fr>
11889 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
11890 looking for a replacement file.
11891 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11892 directory is relative.
11893 * doc/autoconf.texi (Generic Functions): Clarify the replacement
11894 directory definition.

11901 Suggested by Pontus Skoeld.
11903 2002-09-05 Akim Demaille <akim@epita.fr>
11905 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11906 (ifnames, autoscan, autom4te): Since we don't only depend on
11907 configure.ac variables (such as VERSION etc.), but also on prefix
11908 and so forth, depend on Makefile, not configure.ac.
11909 Reported by Alexandre Duret-Lutz.
11910 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11912 2002-09-05 Kevin Ryde <user42@zip.com.au>
11914 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11915 doesn't seem to be confined to ia64, just say "some versions".
11917 2002-09-04 Akim Demaille <akim@epita.fr>
11919 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11920 Automake 1.6c.
11921 * Makefile.am (maintainer-clean-local): Remove.
11922 (MAINTAINERCLEANFILES): Remove COPYING.
11924 2002-09-03 Paul Eggert <eggert@twinsun.com>

11928 Brinkmann.
11930 2002-09-03 Akim Demaille <akim@epita.fr>
11932 * configure.ac: Bump to 2.53d.
11933 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11934 as of today, on Automake's team suggestion.
11936 2002-09-03 Akim Demaille <akim@epita.fr>
11938 Version 2.53c.
11940 2002-09-02 Akim Demaille <akim@epita.fr>

11946 2002-09-02 Jim Meyering <meyering@lucent.com>
11948 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11949 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11950 Also, tweak grammar: s/make sure to/be sure to/.
11952 2002-09-02 Paul Eggert <eggert@twinsun.com>
11954 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11955 directory names are generally preferable to physical names.
11957 2002-09-02 Akim Demaille <akim@epita.fr>
11959 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11960 Reported by Raja R. Harinath.
11961 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11962 * bin/autoupdate.in: Use error instead of die.
11964 2002-09-01 Paul Eggert <eggert@twinsun.com>
11966 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11967 ordinary shell concatenation rather than echo+tr+sed command that
11968 runs afoul of a long-line-related sed bug in Solaris 8.
11970 * bin/autoheader.in (parse_args): --warning -> --warnings.
11972 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11973 stdout, as traditional "ls" does.
11974 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11975 _AC_COMPILER_EXEEXT_O): Likewise.
11976 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11978 * bin/autoconf.as: Add --prepend-include option. This patch was
11979 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11980 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11982 * bin/autoconf.in, configure: Regenerate.
11984 * doc/autoconf.texi (Special Shell Variables): Mention
11985 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11987 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11988 MAILPATH and set PS1, PS2, PS4 to default values, to work
11989 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11990 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11991 the Autoconf documentation specifies; fall back to "unset" only if
11992 this fails. Use a shell for-loop for this rather than an m4 loop,
11993 to shorten the output script.
11995 2002-08-30 Paul Eggert <eggert@twinsun.com>
11997 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11998 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11999 for the CDPATH problem. Document PWD.
12000 (Limitations of Builtins): Document the problem that "cd $foo" and
12001 "ls $foo" may refer to different directories in shells conforming
12002 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12003 example, since the old example is now out of date.
12005 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12006 FOO" and "ls FOO" talk about different directories; this catches
12007 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12008 spaghetti.
12010 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12011 of rolling our own unset.
12012 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12013 in practice we needn't worry about CDPATH if unset doesn't work.
12015 * Makefile.in, aclocal.m4, bin/Makefile.in,
12016 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12017 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12018 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12019 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12020 tests/Makefile.in: Regenerate with Automake 1.6.3.
12022 * config/config.guess, config/config.sub, config/mkinstalldirs:
12023 Update.
12025 * configure: Regenerate with self.
12027 2002-08-30 Kevin Ryde <user42@zip.com.au>
12029 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12030 default output.
12032 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12034 * bin/autom4te.in (Request::load): Correctly test for "do" read
12035 failure.
12037 2002-08-29 Akim Demaille <akim@epita.fr>
12039 * lib/Autom4te/General.pm (&xqx): New.
12040 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12041 hand, which is not portable.
12042 (&error): New.
12043 * bin/autom4te.in: Use them.
12044 Use &error instead of die.
12045 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12046 Adjust.
12048 2002-08-17 Paul Eggert <eggert@twinsun.com>
12050 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12051 default list of compilers to try, since it was long ago superseded
12052 by the ksh fc builtin. Suggested by Steven G. Johnson.
12054 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12056 * doc/autoconf.texi (Invoking autom4te): End the option table,
12057 fixing a bug introduced by the previous patch.
12058 (Limitations of Make): Add a 'target lookup' subentry in the
12059 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12061 2002-07-29 Mark D. Roth <roth@feep.net>
12063 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12064 options and use $AUTOM4TE_PATH.
12065 * doc/autoconf.texi: Remove documentation of autom4te
12066 --include-envvar and --site-macro-subdir options and document
12067 use of $AUTOM4TE_PATH.
12068 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12069 arguments from each language section.
12071 2002-07-29 Paul Eggert <eggert@twinsun.com>
12073 * doc/install.texi: Include copyright symbol in copyright notice.
12075 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12076 Replace with:
12077 (AM_MAKEINFOFLAGS): New macro.
12078 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12079 * Makefile.am (INSTALL): Use the new macros.
12080 Use -o rather than --output, since "missing" does not grok --output.
12082 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12084 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12085 comments do not always work. Never trust the exit status of
12086 `make -k'.
12088 2002-07-24 Kevin Ryde <user42@zip.com.au>
12090 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12091 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12093 2002-07-23 Paul Eggert <eggert@twinsun.com>
12095 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12096 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12097 apparently treats PATH="nonexistent" as if it contained ".".
12098 Bug reported by Stefan `Sec' Zehl.
12100 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12102 * doc/autoconf.texi (Limitations of Make): Mention the special

12119 2002-07-18 Akim Demaille <akim@epita.fr>
12121 Version 2.53b.
12123 2002-07-18 Akim Demaille <akim@epita.fr>
12125 * config/config.guess, config/config.sub: Update.
12127 2002-07-18 Akim Demaille <akim@epita.fr>
12129 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
12130 Automake's parts.

12155 * lib/Autom4te/General.pm (find_file): Browse the directories in

12178 * lib/autom4te.in: Use --prepend-include instead of --include.
12179 * tests/wrapsh.in: Use --prepend-include instead of --include.
12181 2002-07-17 Akim Demaille <akim@epita.fr>

12217 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
12219 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
12220 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,

12222 so that Emacs setups GNU style for perl-mode and cperl-mode.
12224 2002-06-27 Paul Eggert <eggert@twinsun.com>
12226 * config/install-sh: Quote $src. Prefer || to test's -o option,
12227 as per "Limitations of Builtins".
12228 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
12229 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
12231 * tests/mktests.sh: Use grep instead of fgrep, as per
12232 "Limitations of Builtins".
12234 2002-06-15 Paul Eggert <eggert@twinsun.com>
12236 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
12237 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
12238 so that we consistently test the just-built programs.
12239 * tests/wrappl.as: Likewise.
12241 2002-06-12 Paul Eggert <eggert@twinsun.com>
12243 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
12244 name, so that symlinks to 'autoconf' work properly. Bug reported
12245 by Bruno Haible.
12246 * bin/autoheader.in (AUTOM4TE): Likewise.
12247 * bin/autoreconf.in (autoconf, autoheader): Likewise.
12248 * bin/autoscan.in (autom4te): Likewise.
12249 * bin/autoupdate.in (autom4te): Likewise.
12251 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
12252 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
12253 on Solaris 2.5.1.
12255 2002-06-11 Andreas Schwab <schwab@suse.de>
12257 * doc/autoconf.texi: Add more dir entries.
12259 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
12261 * bin/autom4te.in ($cache): Don't define using `$me', the name
12262 of the cache should not depend on the name under which autom4te
12263 was installed.
12265 2002-06-07 Akim Demaille <akim@epita.fr>
12267 * tests/tools.at (autoconf: forbidden tokens, basic)
12268 (autoconf: forbidden tokens, exceptions): Adjust to the change of
12269 words in autom4te.in.
12271 2002-06-07 Peter Eisentraut <peter_e@gmx.net>

12276 2002-06-07 Akim Demaille <akim@epita.fr>
12278 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
12279 rename as...
12280 (AC_REPLACE_FNMATCH): this.
12281 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
12282 AC_FUNC_FNMATCH_GNU.
12284 2002-06-07 Akim Demaille <akim@epita.fr>

12287 Rosetta Stone for Unix.
12289 2002-06-07 Akim Demaille <akim@epita.fr>
12291 * bin/autom4te.in (warn_forbidden): When rejecting a token,
12292 suggest m4_pattern_allow.
12293 Suggested by Adam J. Richter.
12295 2002-06-07 Akim Demaille <akim@epita.fr>
12297 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
12298 ac_config_libobj_dir.
12299 (AC_CONFIG_LIBOBJ_DIR): New.
12300 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
12301 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
12302 Use ac_config_libobj_dir to find the replacement files.
12303 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
12304 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)

12308 * tests/mktests.sh (ac_exclude_list): Don't check
12309 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
12311 2002-06-06 Paul Eggert <eggert@twinsun.com>
12313 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
12314 if ln doesn't work.
12315 * NEWS: Likewise.
12316 * doc/autoconf.texi (Configuration Links): Likewise.
12317 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
12319 2002-06-05 Paul Eggert <eggert@twinsun.com>
12321 * config/config.guess, config/config.sub, config/texinfo.tex:
12322 Update from masters.
12324 2002-05-29 Paul Eggert <eggert@twinsun.com>
12326 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.

12339 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
12340 * doc/autoconf.texi (Particular Programs): Document them.
12341 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
12342 * NEWS: Likewise.
12344 2002-05-27 Paul Eggert <eggert@twinsun.com>
12346 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
12347 * NEWS, doc/autoconf.texi (Particular Types): Document it.
12348 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
12349 instead of AC_MBSTATE_T, which never existed.
12351 2002-05-23 Akim Demaille <akim@epita.fr>
12353 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
12354 version of Autoconf that is discussed.
12356 2002-05-22 Paul Eggert <eggert@twinsun.com>
12358 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
12359 from the default list of compilers to try. Suggested by
12360 Kate Hedstrom.
12361 * NEWS: Document the above.
12362 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
12364 2002-05-17 Paul Eggert <eggert@twinsun.com>
12366 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12367 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12368 This improves on an earlier suggestion by H. Peter Anvin.
12370 2002-05-16 Paul Eggert <eggert@twinsun.com>
12372 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12373 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12374 Both macros now accept an optional source-dir arg.
12375 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12377 * NEWS: Document this.
12378 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12380 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12381 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12382 not for GNU extensions; this undoes part of the 2000-11-03 change,
12383 reverting to 2.13-compatible behavior.
12384 Add new optional argument DIR.
12385 (AC_FUNC_FNMATCH_GNU): New macro.
12387 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12389 2002-05-08 Paul Eggert <eggert@twinsun.com>
12391 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12392 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12393 and it causes a 'test' syntax error if it fails.
12394 Bug reported by Stephen Gildea.
12396 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12397 If prototypes are supported, use them to check this at compile-time,
12398 instead of trying to check it at run-time. If we must do a run-time
12399 check, assume that setvbuf is standard when cross-compiling, as
12400 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12401 Bug reported by Paul D. Smith.
12403 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12404 argument specifying location of getloadavg.c. This removes a
12405 FIXME. This idea was taken from Jim Meyering's implementation in
12406 textutils.
12407 * doc/autoconf.texi (Particular Functions): Document this.
12408 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12409 that's what the code does; this fixes a bug reported by
12410 Paul D. Smith.
12412 2002-05-03 Akim Demaille <akim@epita.fr>
12414 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12415 autopoint instead of gettextize.
12416 ($uses_alocal): Rename as...
12417 ($uses_aclocal): this.
12418 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12419 Suggested by Bruno Haible.
12421 2002-05-03 Akim Demaille <akim@epita.fr>
12423 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12425 2002-04-29 Paul Eggert <eggert@twinsun.com>
12427 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12428 files to be 1 second older; just set them to be the same time.
12429 Also, sleep 1 second after the first aclocal, to work around
12430 problems with sub-second time stamps on the input files.
12432 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12434 * doc/autoconf.texi: Mention "set -e -x" lossage
12435 under node "Limitations of Builtins".
12437 2002-04-29 Akim Demaille <akim@epita.fr>
12439 * doc/install.texi: Better wording for setting variables when
12440 running configure.
12441 From Christian Cornelssen.
12443 2002-04-29 Akim Demaille <akim@epita.fr>
12445 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12446 of lack of $LINENO support, then the test will compare the $LINENO
12447 in testsuite vs. the lineno in the test file. This is wrong, of
12448 course.
12449 Be sure to protect it.
12450 Reported by Patrick Welche.
12452 2002-04-25 Akim Demaille <akim@epita.fr>
12454 * doc/autoconf.texi (Obsolete Macros): Typo.
12455 Reported by Vladimir Volovich.
12457 2002-04-25 Akim Demaille <akim@epita.fr>
12459 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12460 than some of the input files, hence, on the second run of aclocal,
12461 if some of its input are younger, make them older.
12462 Suggested by Paul Eggert.
12464 2002-04-25 Akim Demaille <akim@epita.fr>
12466 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
12467 Thanks to Paul Eggert.
12469 2002-04-25 Akim Demaille <akim@epita.fr>
12471 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12472 and ac_subst_vars be sh variables containing the list of
12473 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12474 DEFAULT diversion.
12475 (_AC_INIT_PREPARE): Use them to log them.
12476 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12477 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12478 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12479 _AC_SUBST_FILES and _AC_SUBST_VARS.
12480 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12482 2002-04-24 Akim Demaille <akim@epita.fr>
12484 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12485 autoheader, so that automake does not complain about a missing
12486 config.h.in that was to be created.
12488 2002-04-23 Akim Demaille <akim@epita.fr>
12490 * bin/autoheader.in (parse_args): --warning takes an argument.

12506 2002-04-22 Akim Demaille <akim@epita.fr>
12508 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
12509 comma.
12510 Reported by Gregory Giannoni.
12512 2002-04-22 Akim Demaille <akim@epita.fr>
12514 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
12515 Fixes false failures on Darwin.

12524 2002-04-20 Paul Eggert <eggert@twinsun.com>

12540 Minor spelling and grammar fixes.
12542 * doc/autoconf.texi: Follow the outline suggested in the GNU
12543 Sample Texts sections of the Texinfo 4.2 manual. Most
12544 importantly, this makes sure that the copyright notices appear in
12545 all output formats. You probably need Texinfo 4.2 to generate
12546 the manual now.
12548 Fix some bugs when using "$@" when there might be zero positional
12549 arguments in cases where this matters.

12570 that is not portable to Zsh.
12572 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
12574 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

12581 2002-04-10 Akim Demaille <akim@epita.fr>
12583 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
12584 workaround for ${1+"$@"}.
12585 * doc/autoconf.texi (Shell Substitutions): Explain it.
12586 From Oliver Kiddle and Peter Stephenson.
12588 Have M4sh perform minimal shell sanitizing.
12590 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12591 part into...
12592 (_AS_PREPARE): this new macro.
12593 (AS_PREPARE): New.
12594 (AS_INIT): Invoke AS_SHELL_SANITIZE.
12595 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
12597 Adjust Autoconf and Autotest.
12599 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12600 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12601 * lib/autotest/general.m4 (AT_INIT): Likewise.
12602 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
12603 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
12604 AS_SHELL_SANITIZE.
12606 Use this M4sh to generate Autoconf's shell scripts.
12608 * tests/wrapsh.as: New, precursor of wrapsh.in.
12609 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12610 on Autotest and M4sh.
12611 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12612 (wrapsh.in): New target.
12613 * bin/autoconf.as: New, precursor of autoconf.in.
12614 (autoconf.in): New target.
12616 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
12618 * doc/autoconf.texi (Limitations of Make): Mention the issue
12619 with indented comments in rules.
12621 2002-04-09 Andreas Schwab <schwab@suse.de>
12623 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
12624 ac_top_builddir when setting ac_abs_top_builddir.
12626 2002-04-06 Kevin Ryde <user42@zip.com.au>
12628 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
12629 (Portable Shell): Cross reference to Systemology.
12631 2002-04-05 Akim Demaille <akim@epita.fr>
12633 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
12634 directories when descending in a SUBDIRS.
12635 Reported by Ezra Peisach.
12637 2002-04-04 Andreas Schwab <schwab@suse.de>
12639 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
12640 contains no literal separators.
12642 2002-04-03 Akim Demaille <akim@epita.fr>
12644 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
12645 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
12646 Use dnl, not the KILL diversion.
12647 Extracted from...
12648 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12649 (AC_CONFIG_LINKS): here.
12650 Adjust.
12651 Don't use the KILL diversion, as it kills spurious output, which
12652 results in failures being hidden.
12653 Use m4_defn where appropriate.
12654 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12655 after the second argument.
12656 Use m4_defn.
12657 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12658 syntax, as it is provided by M4sugar.
12659 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
12661 2002-04-03 Andreas Schwab <schwab@suse.de>
12663 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
12664 expanded if $# <= 2.
12666 * bin/autoreconf.in (autoreconf): Run automake after rerunning
12667 aclocal.
12669 2002-04-03 Akim Demaille <akim@epita.fr>

12674 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
12675 (_AC_COMPILER_OBJEXT): Use them.
12676 Fixes Debian #138666.
12678 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
12680 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12682 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12683 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12684 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
12685 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
12686 (AC_C_CONST): Same.
12687 (AC_C_INLINE): Same.
12688 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
12689 * doc/autoconf.texi, NEWS: Document.
12690 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
12691 AC_C_CROSS.
12693 2002-04-02 Akim Demaille <akim@epita.fr>

12696 _AS_MKDIR_P_PREPARE.
12698 2002-03-28 Kevin Ryde <user42@zip.com.au>
12700 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12701 to avoid versions of HP C which don't allow that.
12703 2002-03-27 Paul Eggert <eggert@twinsun.com>
12705 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12706 (AS_SHELL_SANITIZE): Invoke it.
12707 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
12709 2002-03-26 Akim Demaille <akim@epita.fr>
12711 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
12713 2002-03-26 Akim Demaille <akim@epita.fr>
12715 * doc/autoconf.texi (Introduction): The GNATS base moved.
12717 2002-03-25 Paul Eggert <eggert@twinsun.com>
12719 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12720 as POSIX requires, as it doesn't work with Zsh.
12721 * doc/autoconf.texi (Assignments): Document the problem.
12723 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12725 * doc/autoconf.texi (Limitations of Make): Mention more issue
12726 about VPATH, overriding of macros in sub-makes, and handling of
12727 SHELL.
12729 2002-03-21 Paul Eggert <eggert@twinsun.com>
12731 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12732 problem with here-document buffer boundaries.
12734 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12735 when reinvoking the shell, to work around problems with installers
12736 who put strange things like "cd" commands in their environments.
12738 2002-03-19 Akim Demaille <akim@epita.fr>
12740 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
12741 From Aaron Ucko.
12743 2002-03-19 Akim Demaille <akim@epita.fr>
12745 * bin/autoscan.in (scan_file): Specify the location in `&used'
12746 invocations.
12747 From Nicolas Joly.
12749 2002-03-19 Akim Demaille <akim@epita.fr>
12751 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
12752 From Nishio Futoshi.
12754 2002-03-19 Akim Demaille <akim@epita.fr>
12756 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
12758 2002-03-18 Paul Eggert <eggert@twinsun.com>
12760 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12761 (Limitations of Usual Tools): Add mkdir section.
12763 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12764 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12765 back on AS_DIRNAME to compute prefixes otherwise; this is
12766 roughly what mkinstalldirs does. That way, we need not have
12767 our own filename disassembler. The old disassembler did not
12768 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12770 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12771 Create at_test_all by a series of assignments,
12772 not by a single assignment of a long string. The latter causes ksh
12773 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12774 presumably because of a buffer overrun.
12776 2002-03-14 Paul Eggert <eggert@twinsun.com>
12778 * lib/autotest/general.m4 (at_times_skip):
12779 Renamed from at_times. Now a boolean.
12780 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12781 says 'times: not found'.
12783 2002-03-14 Akim Demaille <akim@epita.fr>
12785 * bin/autoreconf.in (&study_gettextize): New.
12786 (&autoreconf): Handle newest gettextize.
12787 Rerun aclocal if needed.
12788 Suggested by Andreas Schwab.
12790 2002-03-13 Akim Demaille <akim@epita.fr>
12792 * doc/autoconf.texi (Special Shell Variables): More about IFS.

12796 * doc/autoconf.texi (Header Portability): New.
12797 Add information about stdint.h and inttypes.h from Paul Eggert.
12799 2002-03-13 Akim Demaille <akim@epita.fr>
12801 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
12802 -p'.
12803 From Bob Proulx.
12805 2002-03-12 Akim Demaille <akim@epita.fr>
12807 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
12808 m4_require.
12810 2002-03-11 Andreas Schwab <schwab@suse.de>
12812 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
12813 does not do it if --with-lispdir is given.
12815 2002-03-08 Akim Demaille <akim@epita.fr>
12817 Version 2.53.
12819 2002-03-08 Akim Demaille <akim@epita.fr>
12821 * doc/autoconf.texi (Subdirectories): Clarify that the
12822 subdirectory should exist.
12824 2002-03-08 Akim Demaille <akim@epita.fr>
12826 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12828 2002-03-08 Akim Demaille <akim@epita.fr>
12830 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12831 aliases the actual variables, and modifications of the former
12832 affect the latter.
12834 2002-03-08 Akim Demaille <akim@epita.fr>
12836 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12837 because of C-c: have m4 output in tmp files, then mv them.
12839 2002-03-08 Akim Demaille <akim@epita.fr>
12841 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
12842 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
12843 * bin/ifnames.in: Copyright update.

12849 2002-03-05 Akim Demaille <akim@epita.fr>
12851 * doc/autoconf.texi (Specifying Names): Clarification suggested by
12852 Kevin Ryde.
12854 2002-03-05 Akim Demaille <akim@epita.fr>
12856 Version 2.52i.
12858 2002-03-04 Akim Demaille <akim@epita.fr>
12860 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
12861 * lib/autoconf/general.m4 (AC_INIT): More informative error
12862 message for LIBOBJ.
12864 2002-03-04 Akim Demaille <akim@epita.fr>
12866 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
12867 parallel builds.
12869 2002-03-04 Akim Demaille <akim@epita.fr>
12871 * doc/autoconf.texi (Transforming Names): Equality between target
12872 and host is irrelevant.
12873 (Specifying Names, Canonicalizing): Remove all references to the
12874 backward compatibility hooks. Rather, collect them all into...
12875 (Hosts and Cross-Compilation): this new section.
12876 * doc/install.texi (System Type): Ditto.
12877 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12878 that `--host' implies cross-compilation.
12880 2002-03-04 Akim Demaille <akim@epita.fr>
12882 * doc/autoconf.texi (Evaluation Macros): New.
12883 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12884 useless.
12885 (_m4_foreach): Define the variant with immediate evaluation so
12886 that it contains exactly the items, not an expression which
12887 evaluation is the current item.
12888 (m4_re_string, m4_re_word): Don't over quote them.
12890 2002-03-04 Akim Demaille <akim@epita.fr>
12892 Instead of having stacking `shift's evaluated at the end, let
12893 `foreach' loops immediately evaluate them.
12895 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12896 $*. This is the n-th time I change my mind, but hopefully this is
12897 the last...
12898 (m4_lquote): New.
12899 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12900 efficient.
12901 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12902 it was only a hack for m4_text_wrap.
12903 (m4_car2): Remove, replaced by...
12904 (m4_cdr): New.
12905 (_m4_foreach): Adjust.
12906 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12907 m4_bpatsubst for clarification.
12909 2002-03-04 Akim Demaille <akim@epita.fr>
12911 * doc/autoconf.texi (Changequote is Evil): New.
12913 2002-03-03 Kevin Ryde <user42@zip.com.au>
12915 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
12916 on old systems like SunOS.

12958 Fix Autoconf PR/207:
12959 AC_PREFIX_PROGRAM fails with dashed program names
12961 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
12962 variable when looking for the prefix program.
12963 Now it also works for shell variables.
12965 2002-02-07 Akim Demaille <akim@epita.fr>

12972 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
12973 case/esac, some shells don't support it.
12974 Reported by Zack Weinberg.
12975 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
12977 2002-02-06 Akim Demaille <akim@epita.fr>
12979 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
12980 sure not to introduce newlines in at_groups.

12983 2002-02-06 Akim Demaille <akim@epita.fr>
12985 * tests/torture.at (Configuring subdirectories): Skip if aclocal
12986 is not available.
12988 2002-02-05 Paul Eggert <eggert@twinsun.com>
12990 * doc/autoconf.texi (Specific Compiler Characteristics):
12991 Describe HP-UX cc bug workaround more accurately.
12992 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
12993 not unsigned long.
12994 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
12995 cross-compilers, too. This undoes some of the most recent change
12996 to this file.
12998 2002-02-05 Akim Demaille <akim@epita.fr>
13000 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
13001 to make sure they are up to date when `check' is run.
13003 2002-02-05 Akim Demaille <akim@epita.fr>
13005 * doc/autoconf.texi (Making testsuite Scripts): Document

13012 2002-02-05 Akim Demaille <akim@epita.fr>
13014 Implement `autom4te --freeze'.
13016 * bin/autom4te.in (&freeze): New.
13017 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
13018 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
13020 2002-02-05 Akim Demaille <akim@epita.fr>
13022 * bin/autom4te.in (&parse_args): Implement `frozen files are
13023 optional are the sum of the previous files on the command line'.
13024 Also, pass `--reload-state=' on them, so...
13025 (handle_m4): don't.
13026 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13027 (M4sh): Rely on M4sugar.
13028 (Autotest, M4sh, M4sugar): Use frozen files.

13032 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.

13062 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13063 needs an argument.
13065 2002-01-28 Akim Demaille <akim@epita.fr>
13067 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13068 AUTOTEST_PATH *after* it was set.
13069 Don't put `.' in the PATH: the user should be precise and `./' if
13070 needed. In addition, given that the test suite does some `cd', if
13071 `.' is in the path, the `tested programs' sections will report
13072 programs found in the test suite's directory, while during the
13073 tests (performed in their own directory), these programs are no
13074 longer visible. In other words, the results is confusing and
13075 useless.
13076 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

13106 Automake.
13108 2002-01-24 Akim Demaille <akim@epita.fr>
13110 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13111 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13112 Reported by Geir Ove Myhr.
13114 2002-01-21 Akim Demaille <akim@epita.fr>
13116 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
13118 2002-01-21 Akim Demaille <akim@epita.fr>
13120 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13121 message on invalid options.
13122 * bin/autom4te.in (parse_args): Don't use
13123 Autoconf::General::getopt with non valid options.
13125 2002-01-17 Jim Meyering <meyering@lucent.com>
13127 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13128 $ac_cv_exeext so we don't use an old, invalid, cached value.
13130 2002-01-11 Akim Demaille <akim@epita.fr>
13132 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
13133 Meyering.

13135 limitation.

13139 2002-01-06 Akim Demaille <akim@epita.fr>
13141 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13142 package.m4, since is really depends upon configure.ac, not
13143 configure.
13144 * doc/autoconf.texi (testsuite Scripts): Adjust.
13145 * tests/Makefile.am (package.m4): New.
13146 EXTRA_DIST it since its a source.
13148 2002-01-06 Akim Demaille <akim@epita.fr>
13150 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13151 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13152 and PACKAGE_BUGREPORT from here...
13153 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13154 arguments.
13155 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13156 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13157 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13158 * tests/tools.at (autoheader): Adjust.
13159 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13161 2002-01-06 Akim Demaille <akim@epita.fr>

13169 From Olly Betts.
13171 2001-12-18 Kevin Ryde <user42@zip.com.au>
13173 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13174 sometimes needing writable input.
13176 2001-12-17 Jim Meyering <meyering@lucent.com>
13178 * doc/autoconf.texi (New Macros): Tweak wording.
13180 2001-12-14 Akim Demaille <akim@epita.fr>
13182 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13183 trailing files, don't apply `-rf' to files which might not be
13184 created by configure (core, core.*, and *.core), but just `rm -f'.
13185 Suggested by Jonathan Kamens.
13187 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13189 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13191 2001-12-14 Akim Demaille <akim@epita.fr>
13193 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13195 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13197 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13198 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13199 abs_srcdir, top_srcpath to abs_top_srcdir.
13200 (_AC_OUTPUT_FILES): Adjust.
13201 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13202 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13203 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13205 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13207 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13208 C/Fortran linking on HP/UX, by extracting the Fortran library
13209 search path from the LPATH line in the $F77 -v output.
13211 2001-12-12 Kevin Ryde <user42@zip.com.au>
13213 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13214 forbidden file descriptors table.
13216 2001-11-26 Akim Demaille <akim@epita.fr>
13218 * bin/autoscan.in (%c_keywords): Build it at top level.
13219 Map to 1 in order to simplify its uses.
13221 2001-11-26 Akim Demaille <akim@epita.fr>
13223 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13224 Remove $filepath, useless.
13225 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13226 variables, they are really part of the tokens.
13227 Split the input line on spaces and then look for tokens.
13228 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13229 because of `lex$U.$(OBJEXT)'.
13230 (&scan_files): Use "@list" instead of join.
13231 * doc/Makefile.am (CLEANFILES): Add *.fns.
13233 2001-11-26 Akim Demaille <akim@epita.fr>
13235 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13236 Remove, replaced by...
13237 * tests/wrappl.in: Be common for all the Perl executables.
13238 In particular autoscan and autoheader want -I.
13239 * configure.ac: Adjust.
13240 * lib/autoscan/headers: errno.h is portable.
13242 2001-11-26 Akim Demaille <akim@epita.fr>
13244 * bin/autoscan.in (used): New.
13245 Use it.
13247 2001-11-26 Akim Demaille <akim@epita.fr>
13249 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13250 directives.
13251 (&scan_sh_file): Remove a duplicate pattern.
13252 (&check_configure_ac): Use long options.
13253 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13255 2001-11-26 Akim Demaille <akim@epita.fr>
13257 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13258 Before, having a line containing the opening of a multi line
13259 comment made the whole line be ignored.
13261 2001-11-26 Akim Demaille <akim@epita.fr>
13263 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13264 (testsuite Scripts): Be one of its subsection.
13265 (Autotest Logs): New.
13267 2001-11-26 Akim Demaille <akim@epita.fr>
13269 Test groups are now run two directories deeper.
13271 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13272 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13273 at_top_builddir.
13274 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13275 top_srcdir, builddir and top_builddir.
13276 Use `at_*dir' relatively to the directory containing the
13277 suite, use `*dir' when relatively to the current group dir.
13279 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13281 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13282 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13283 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13284 spelling errors.
13286 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13288 * doc/autoconf.texi (Using System Type): Add an example of `case
13289 $host' usage so people quit using `case $target' everywhere.
13291 2001-11-22 Akim Demaille <akim@epita.fr>
13293 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13294 spotted by Jim Meyering.
13296 2001-11-16 Paul Eggert <eggert@twinsun.com>
13298 This patch implements a `long double' suggestion by Oliver Kiddle.
13300 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13301 static, to catch errors if the value isn't known at compile-time
13302 and the compiler supports dynamic arrays. Change its name from
13303 `_array_' to `test_array' to avoid potential name clashes.
13304 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13305 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13306 better than double. Catch a bug in GCC 2.95.2 x86.
13307 * doc/autoconf.texi (C Compiler): Document the above.
13308 * NEWS: Likewise.
13310 2001-11-13 Akim Demaille <akim@epita.fr>
13312 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13313 hand.
13314 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13316 2001-11-13 Akim Demaille <akim@epita.fr>
13318 * lib/autotest/general.m4 (AT_INIT): After having run the test
13319 group, go back to the initial directory, not to at_suite_dir.
13321 2001-11-13 Akim Demaille <akim@epita.fr>
13323 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13324 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13325 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13326 option.
13327 (AT_CHECK_CONFIGURE): Use absolute paths.
13328 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13329 The problem is still the old one: there is no means in M4 (that I
13330 know about) to create a defining macro, because there is no means
13331 to create `$1' etc., therefore, the defining macro ``swallows''
13332 all the arguments meant to the defined macro.
13334 2001-11-13 Akim Demaille <akim@epita.fr>
13336 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13337 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13338 configure.ac.
13339 * tests/aclocal.m4: Remove, as it is no longer used.
13341 2001-11-13 Akim Demaille <akim@epita.fr>
13343 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13344 variable names when referring to a single test group, or to
13345 `suite' when referring to the whole test suite.
13346 `at_last_test' is removed: m4 compute at_format itself.
13347 (at_stdout, at_stder1, at_stderr): New variables.
13348 (AT_CHECK): Use them.
13350 2001-11-13 Akim Demaille <akim@epita.fr>
13352 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13353 in PATH.
13354 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13355 Do it as soon as a test fails, don't wait till the end of the test
13356 suite.
13357 Don't remove $as_me.[0-9]*, since these files no longer exist.
13359 2001-11-13 Akim Demaille <akim@epita.fr>
13361 * tests/tools.at: Use absolute paths, since we are no longer run
13362 in place.
13364 2001-11-13 Akim Demaille <akim@epita.fr>
13366 Now that tests are running in their own private dir, there is no
13367 need to list the files to remove at the end of tests groups.
13369 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13370 (AT_data_files, at_data_files): Remove.
13371 (AT_CLEANUP, AT_DATA): Simplify.
13372 (AT_INIT): Adjust.
13373 Remove the group dir if !debug && !failed.
13374 * tests/atspecific.m4: Adjust.
13376 2001-11-13 Akim Demaille <akim@epita.fr>
13378 Start a new layout for Autotest: `testsuite' creates
13379 `testsuite.dir' in which the at-check-line etc. files are to be
13380 found, and `testsuite.dir/003' where the test group 3 is run.
13382 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13383 at_check_line_file, at_format, at_test_normalized, at_group_dir
13384 are new variables.
13385 Create the directories.
13386 Use absolute paths for at- files.
13387 (AT_CHECK): Adjust.
13389 2001-11-11 Michael Matz <matz@kde.org>
13391 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13392 (m4_car2): New.
13393 (m4_car): Properly quote arguments.
13395 2001-11-13 Akim Demaille <akim@epita.fr>
13397 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13398 with stricter rules on LIBOBJS.
13400 2001-11-12 Paul Eggert <eggert@twinsun.com>
13402 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13403 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13404 __PROTOTYPES too.
13406 2001-11-12 Akim Demaille <akim@epita.fr>
13408 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13410 2001-11-12 Akim Demaille <akim@epita.fr>
13412 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13413 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13414 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13415 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13416 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13417 specify to what the macro should be defined (typically to 1).
13419 2001-11-12 Akim Demaille <akim@epita.fr>
13421 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13422 From Jim Meyering.
13424 2001-11-12 Akim Demaille <akim@epita.fr>
13426 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13427 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13428 definition used by Automake where LEX is +/- "${missing} lex" and
13429 `missing' itself contains variables.
13431 2001-11-12 Akim Demaille <akim@epita.fr>
13433 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13434 Now that M4sh pushes BODY, the comments were output at the end of
13435 the test suites.
13437 2001-11-08 Akim Demaille <akim@epita.fr>
13439 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13440 that we can trace macros from aclocal.m4.
13441 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13442 obsoleted, and redirect to the former anyway.
13443 Reported by Ralf Corsepius.
13445 2001-11-08 Akim Demaille <akim@epita.fr>
13447 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13448 processed only if present.
13449 * tests/torture.at (Configuring subdirectories): Use autoreconf
13450 instead of successive calls to autoconf.
13451 Add a nonexistent subdirectory to exercise the patch above.
13452 Reported by Ralf Corsepius.
13454 2001-11-08 Kevin Ryde <user42@zip.com.au>
13456 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13457 doesn't accept .S files.

13464 * bin/autom4te.in (warn_forbidden): New.
13465 (handle_output): Use it.
13466 Read m4_pattern_forbid with messages.
13468 2001-11-05 Akim Demaille <akim@epita.fr>
13470 * bin/autom4te.in (--normalize): Remove.
13471 * lib/autom4te.in: Adjust.
13473 2001-11-05 Akim Demaille <akim@epita.fr>
13475 * tests/Makefile.am (testsuite): Rename this target as...
13476 ($(TESTSUITE)): this.
13477 From Nicolas Joly.
13479 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13481 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13482 the --prefix option, also remove it's argument.
13484 2001-11-05 Akim Demaille <akim@epita.fr>
13486 * doc/autoconf.texi (testsuite Invocation): Update.
13487 (Writing testsuite.at): Update.

13495 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13496 (&file_name_is_absolute): New, wrappers around routines from
13497 File::Spec.
13498 Use and export them.
13499 (&find_configure_ac): Optionally take a directory where to look at.
13500 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13501 the arguments.
13502 Default @ARGV to `.', not find_configure_ac.
13503 (&autoreconf): Argument is a directory.
13504 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13505 * doc/autoconf.texi (autoreconf Invocation): Update.
13507 2001-11-03 Akim Demaille <akim@epita.fr>
13509 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13510 (@export_forward_subs): New.
13511 Add basename, dirname, and fileparse.
13512 (@EXPORT): Adjust.
13513 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13514 Don't look for aclocal flags if we already know aclocal is not
13515 used.
13516 Move aclocal.m4t only if it exists.
13517 Reported by Ezra Peisach.
13519 2001-11-03 Akim Demaille <akim@epita.fr>
13521 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13522 passed on command line, defaulting to ./configure.ac if present.
13523 (&maybe_autoreconf, File::Find): Remove, unused.
13524 (&autoreconf): If autoconf is not used, don't try to trace.
13526 2001-11-02 Akim Demaille <akim@epita.fr>
13528 * configure.ac: Bump to 2.52g.
13530 2001-11-02 Akim Demaille <akim@epita.fr>
13532 Version 2.52f.
13534 2001-11-02 Akim Demaille <akim@epita.fr>
13536 * config/config.guess, config/config.sub, doc/standards.texi:
13537 * config/lispdir.m4: Update from masters.
13538 * configure.ac: Bump to 2.52f.
13540 2001-11-02 Akim Demaille <akim@epita.fr>
13542 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13543 Don't run aclocal when aclocal.m4 is not from aclocal.
13544 From Ezra Peisach.
13545 Don't run libtoolize and gettextize if --install is not given.
13547 2001-11-01 Paul Eggert <eggert@twinsun.com>
13549 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13550 be invoked before _AS_LINENO_PREPARE.
13551 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13552 than character ranges.
13554 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13555 invoking AS_BASENAME. Set the locale variables to 'C' if
13556 possible, as POSIX requires this to get the traditional
13557 behavior.
13558 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13560 2001-10-31 Paul Eggert <eggert@twinsun.com>
13562 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13563 with {}, as that triggers a bug in Bash 2.05.
13565 (_AS_LINENO_PREPARE): Use Sed rather than
13566 Awk. Fix the sed prepass to work even if there are multiple
13567 instances of $LINENO on the same line. Do not substitute for
13568 other variables like $LINENOT. Do not check file dates; such a
13569 check is unreliable on sufficiently fast machines, and removing
13570 the check makes the code simpler and more reliable. Check for
13571 output and chmod failures.
13573 * doc/autoconf.texi (Special Shell Variables): Document
13574 the above.
13576 2001-10-31 Akim Demaille <akim@epita.fr>
13578 * tests/Makefile.am (atconfig): Remove this target, Automake
13579 handles it now.
13581 2001-10-31 Akim Demaille <akim@epita.fr>
13583 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13584 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13585 provided, while it is optional.
13586 * configure.ac: Adjust.
13588 2001-10-26 Paul Eggert <eggert@twinsun.com>
13590 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13591 lib/Autom4te/Struct.pm:
13592 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13593 with 5.005_02.
13595 * doc/autoconf.texi (Special Shell Variables): Document some
13596 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13598 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13599 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13600 eval $LINENO is not portable in practice.
13602 2001-10-24 Akim Demaille <akim@epita.fr>
13604 * lib/Autom4te/General.pm (backname): New.
13606 2001-10-24 Akim Demaille <akim@epita.fr>
13608 * m4/: Remove, merged into...
13609 * config/: here.
13611 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
13613 * doc/autoconf.texi (Shellology): Mention the problems with bash
13614 2.05's use of ANSI quoting in its `set' builtin.
13616 2001-10-22 Paul Eggert <eggert@twinsun.com>
13618 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13619 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13620 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13621 POSIX decided to standardize on the int flavor of strerror_r.
13622 Always do char* test, as there's no reason not to.
13623 Assign to a char* var, to catch strerror_r that returns int*.
13625 * doc/autoconf.texi (Particular Functions):
13626 Document the above changes. Also, document the fact that
13627 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13629 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13631 2001-10-20 Akim Demaille <akim@epita.fr>
13633 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
13634 the executable was missing from the log.

13638 * lib/Autom4te/General.pm (&update_file): If destination is
13639 unchanged, remove the source.
13640 (&up_to_date_p): Don't be verbose, be debug.
13641 * bin/autoreconf.in: No longer support --m4dir.
13642 (&autoreconf): Display the full path of the configure.ac we are
13643 studying.
13644 Trace it only once.
13645 Be sure to honor --force with gettextize.
13646 Always run aclocal.
13647 * doc/autoconf.texi: Adjust.
13649 2001-10-20 Akim Demaille <akim@epita.fr>
13651 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13652 Remove, dead.
13653 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13654 `intl' is already present, as it refuses unless --force.
13655 (&parse_args): Use -I, --include instead of the old Autoconf
13656 options.
13657 ($localdir, $autoconf_dir): Remove.
13658 (@include): New.
13659 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13661 2001-10-19 Jens Petersen <petersen@redhat.com>

13669 file in @configure_input@.
13670 Don't mention `automatically' in addition to `generated'.
13671 * tests/torture.at (#define header templates): Adjust.
13673 2001-10-19 Akim Demaille <akim@epita.fr>
13675 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
13676 comment, explain how to install automatic mode selection.
13677 From Russ Allbery.
13679 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
13681 * bin/autoreconf.in (autoreconf): Display the path to the
13682 configure.ac being studied.
13684 2001-10-18 Paul Eggert <eggert@twinsun.com>
13686 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13687 long, to work around a bug in the HP C compiler version HP92453-01
13688 B.11.11.23709.GP.
13690 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13691 (AS_BASENAME_EXPR): New macro.
13692 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13693 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13694 and fall back on 'sed' only if the other two fail. This makes
13695 AS_BASENAME act more like AS_DIRNAME.
13696 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13697 contains white space.
13698 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13699 Use AS_DIRNAME, since I think it's now DOS-friendly.
13700 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
13701 Allow "dirname //FOO" to return either / or //, as POSIX allows
13702 either behavior.
13704 2001-10-10 Akim Demaille <akim@epita.fr>
13706 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

13708 From Eric Sharkey.

13712 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

13807 2001-10-08 Akim Demaille <akim@epita.fr>
13809 Use `add-log-current-defun-function' for ChangeLog creation.

13831 * tests/tools.at (AT_DATA_FORBIDDEN): New.

13842 empty, and if we can find a shell that does support LINENO,
13843 then set CONFIG_SHELL to that shell and then re-execute
13844 ourselves with CONFIG_SHELL.
13846 2001-10-05 Paul Eggert <eggert@twinsun.com>
13848 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
13849 doesn't exist. Remove *.tmp, as a .tmp file is created during the
13850 build of $(TESTSUITE).
13852 2001-10-05 Akim Demaille <akim@epita.fr>
13854 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

13863 Fix the absolute path case/esac pattern.
13864 Provide $0 as fallback for as_myself.

13874 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): New, extracted from...
13875 (AS_SHELL_SANITIZE): here. Use it.
13876 (_AS_LINENO_PREPARE): Preserve the exit status of $0.lineno.
13877 From Paul Eggert.
13879 2001-10-04 Akim Demaille <akim@epita.fr>
13881 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
13882 combination of Awk and sed to replace $LINENO.
13884 2001-10-02 Paul Eggert <eggert@twinsun.com>
13886 * doc/autoconf.texi (Limitations of Builtins): You can't use
13887 "source"; it's not portable. Remove confusing and
13888 somewhat-incorrect example involving "." and "/".
13890 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
13891 compatibility with POSIX shells.
13893 2001-10-02 Akim Demaille <akim@epita.fr>
13895 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
13896 instead of exec'ing to preserve $0 and $@.
13898 2001-10-01 Akim Demaille <akim@epita.fr>
13900 * tests/testsuite (AT_INIT) <at_pass_list>: New.
13901 Don't run twice the same test.

13919 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
13920 Don't use nested parenthesization. This patch was originally
13921 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
13922 but somehow it didn't get incorporated then.
13923 * doc/autoconf.texi (Limitations of Usual Tools):
13924 Clarify remark about sed and nested parenthesization.
13926 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
13927 Report an error if the size cannot be determined even though
13928 the type exists.
13929 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13930 Check for `expr' arithmetic overflow, and for compilation failure,
13931 and invoke a new argument $4 if either is discovered.
13932 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13933 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
13935 2001-09-28 Akim Demaille <akim@epita.fr>

13943 * lib/autotest/general.m4 (AT_VICTIMS): Rename as...
13944 (AT_TESTED): this.
13945 (AT_INIT): More the wrapped section to where it will be expanded.
13946 Output `AT_tested' only when existing.
13947 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
13949 2001-09-27 Akim Demaille <akim@epita.fr>
13951 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
13952 generates too many bug reports.
13954 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
13955 status when executing the ACTION-IF-FALSE.
13956 * tests/base.at (AC_TRY_*): Rename as...

13963 * tests/c.at (Extensions, C keywords)
13964 (Broken/missing compilers, AC_PROG_CPP with warnings)
13965 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
13966 (AC_PROG_CPP requires AC_PROG_CC): here and...
13967 * tests/fortran.at (GNU Fortran 77): there.
13968 * doc/autoconf.texi (autoconf Invocation): Fix the example:
13969 AC_TRY_RUN is about compilation, not shell commands.
13970 (Test Programs): AC_TRY_RUN works as used to be advertised.
13972 2001-09-27 Akim Demaille <akim@epita.fr>
13974 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
13975 Raja R Harinath:
13976 Be sure to detect when $LINENO always returns the same value.
13977 Look for the original script, basename($0) is certainly not
13978 enough.
13979 Pass the CLI arguments to `$as_me.lineno'.
13981 2001-09-25 Akim Demaille <akim@epita.fr>
13983 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

13995 * doc/autoconf.texi (Top): Wrap in @ifnottex.
13997 2001-09-23 Akim Demaille <akim@epita.fr>
13999 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
14000 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
14001 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
14002 builddir, buildpath, top_builddir, and top_buildpath.
14003 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
14004 the current directory.
14005 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
14006 variables *before* changing the current directory.

14009 variables.
14011 * lib/autotest/general.m4: Do not reset AT_victims.
14012 Don't compute at_srcdir nor at_top_srcdir.
14014 * tests/tools.at: Hence use top_srcdir.
14016 * tests/Makefile.am, tests/autoconf, tests/autoheader,
14017 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
14018 Remove.
14019 * tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,
14020 * tests/wrapsh.in, tests/autoupdate.in: New.
14021 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
14022 * configure.ac: Build the position independent wrappers.
14024 * man/Makefile.am: Now that test wrappers are position
14025 independent, use them and drop dark envvar magic.
14027 2001-09-23 Akim Demaille <akim@epita.fr>
14029 * doc/autoconf.texi (Common Shell Constructs): Rename as...
14030 (Programming in M4sh): this.
14031 Promote to @section.

14060 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
14062 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,

14074 * tests/Makefile.am (package.m4): Remove.
14076 2001-09-22 Akim Demaille <akim@epita.fr>
14078 Rely on `$LINENO' when possible instead of `__oline__'.
14080 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
14081 `$LINENO' support replacement when not supported.
14082 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
14083 them explicitly to be sure they are not output before this section
14084 (via m4_require). Cosmetic only.
14085 * lib/autoconf/c.m4, lib/autoconf/general.m4,
14086 * lib/autoconf/programs.m4: Replace all the occurrences of
14087 `__oline__' with `$LINENO'.
14088 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
14090 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
14092 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
14093 character (u: -> ue) in a code comment.
14094 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
14095 it works.
14097 2001-09-21 Akim Demaille <akim@epita.fr>
14099 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
14100 Suggested by Jim Meyering.
14102 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14104 * lib/autoconf/programs.m4: Use extensions listed in
14105 $ac_executable_extensions when looking for programs.
14107 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14109 * lib/autoconf/general.m4: Fix a small Englisho.
14110 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
14111 setting up ac_dir_suffix and ac_top_builddir.
14112 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
14114 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14116 * doc/autoconf.texi (File System Conventions): Clarify the use of
14117 PATH_SEPARATOR.
14118 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
14119 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
14120 be used instead of ':'.
14121 * lib/autotest/general.m4: Replace occurrences of ':' in
14122 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14124 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14126 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14127 arguments. Fixed a typo.
14129 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14131 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14132 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14134 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14136 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
14137 * bin/autoupdate.in: Ditto.
14138 * bin/autoheader.in: Reworded a few comments.
14139 * bin/autoconf.in: Reworded help text for a few options.
14140 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
14141 * bin/autoscan.in, bin/autoupdate.in: Ditto.
14143 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14145 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14146 already have $file). Set output files to binary mode (helps avoid
14147 CR issues on DOSish systems).
14149 2001-09-19 Akim Demaille <akim@epita.fr>
14151 * lib/autotest/general.m4: Englishoes.
14152 From Tim Van Holder and Alexey Mahotkin.
14154 2001-09-18 Paul Eggert <eggert@twinsun.com>
14156 * doc/autoconf.texi (Common Shell Constructs): New node,
14157 documenting AS_DIRNAME.
14158 (Limitations of Usual Tools): Refer to it when discussing dirname.
14159 Also, update discussion of POSIX standard to reflect latest draft.
14161 * lib/autoconf/c.m4:
14162 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14164 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14165 Do not pass a first argument with leading '-'
14166 to expr, by parenthesizing initial integers that might be negative.
14168 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14169 now merely checks whether it is an error to pass an argument
14170 to getpgrp.
14172 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14173 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14174 whether it is a (compile-time) error to pass an argument to
14175 getpgrp. This simpler test supports the revised documentation,
14176 and is all that AC_FUNC_GETPGRP's users really need.
14178 2001-09-18 Akim Demaille <akim@epita.fr>
14180 * doc/autoconf.texi (Limitations of Make) <$<>: New.
14182 2001-09-18 Akim Demaille <akim@epita.fr>
14184 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
14185 `{}'.

14188 2001-09-18 Paul Wagland <paul@wagland.net>
14190 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14191 correctly.
14192 Add test for AS_BASENAME.
14193 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14194 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14195 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14196 * tests/base.at: Fixed the expected responses. The old ones were
14197 one line out...
14198 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14199 the documentation claims it should (and how it behaved in 2.13).
14201 2001-09-18 Akim Demaille <akim@epita.fr>
14203 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14204 the AC_CONFIG_COMMANDS invocation.
14205 This also solves the name clash problems.
14206 Don't set the package's ID.
14207 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14208 No longer to be shipped.
14209 (version.in): Remove.
14210 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14211 * lib/autoconf/status.m4: Adjust.
14212 Use `m4_PACKAGE_STRING'.
14213 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14214 the only optional argument is the name of the test suite.
14215 Expect `package.m4' to define the package signature.
14216 * lib/autom4te.in (Autotest): Add `package.m4?'.
14217 * tests/Makefile.am (package.m4): New.
14218 * tests/suite.at: ifnames is a victim.
14220 2001-09-18 Akim Demaille <akim@epita.fr>
14222 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14223 AC_LIBSOURCE, AC_CONFIG_FILES.
14224 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14225 program version string doesn't match the package's.
14226 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14227 after `(cached)'.
14229 2001-09-17 Paul Eggert <eggert@twinsun.com>
14231 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14232 Allow expression to return any value that can fit into unsigned long
14233 (not int, as before). Check for output errors.
14235 2001-09-17 Bruno Haible <haible@ilog.fr>
14237 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14238 Always include <stdio.h> and <stdlib.h>. Evaluate
14239 the expression in an extra function before these includes. Call
14240 fprintf "%d" only after ensuring the argument is of type 'int'.
14241 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14243 2001-09-17 Paul Eggert <eggert@twinsun.com>
14245 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14246 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14247 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14248 when they don't exist.
14250 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14251 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14252 need it.
14254 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14255 version with the version used by fileutils 4.1, except use
14256 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14257 we don't need it.
14259 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14261 2001-09-13 Akim Demaille <akim@epita.fr>
14263 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
14264 _first_.
14265 Reported by Gerrit P. Haase.
14267 2001-09-13 Akim Demaille <akim@epita.fr>
14269 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
14270 m4_defn'ing is valid.
14272 2001-09-13 Akim Demaille <akim@epita.fr>
14274 * lib/m4sugar/m4sugar.m4 (m4_append_uniq): New.
14275 * lib/autotest/general.m4 (AT_VICTIMS, AT_KEYWORDS, _AT_CLEANUP_FILE):
14276 Use it.
14278 2001-09-13 Akim Demaille <akim@epita.fr>
14280 * lib/m4sugar/m4sugar.m4 (_AS_QUOTE_IFELSE, _AS_BOX_INDIR): Use
14281 m4_match.
14282 (m4_re_escape): New.
14283 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER): Use it.
14284 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
14285 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
14286 Likewise.
14287 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
14288 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
14289 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
14290 AT_tests_all for consistency.
14291 Set at_victims.
14292 (AT_VICTIMS): Similar to AT_KEYWORDS.
14293 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
14295 2001-09-13 Akim Demaille <akim@epita.fr>
14297 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.

14301 * lib/autotest/general.m4 (AT_INIT): Create and remove
14302 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

14413 2001-09-05 Akim Demaille <akim@epita.fr>
14415 Be ready to handle filenames as stupid as `dnl.at', for if even
14416 the maintainer is dumb enough to do that...
14418 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14419 excellence in M4 quotation: consider `__file__' is active.
14421 And BTW, when invoking m4, pass the --include in the right order:
14422 the wrong one.
14424 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
14425 4m.

14449 CVS GNU M4 doesn't like `undefine(undefined)'.
14451 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
14452 New, extracted from main.
14453 Use IO::File wherever possible.
14454 (input.m4): Be constant, use -I instead of hard coding $tmp.
14455 Therefore be a quoted heredoc.
14456 Don't invoke `_au_disable', since ac was not loaded, but just
14457 `unm4.m4'.
14459 2001-08-31 Akim Demaille <akim@epita.fr>
14461 Version 2.52d.

14484 2001-08-31 Akim Demaille <akim@epita.fr>
14486 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
14487 (testsuite Scripts): There is no such thing as `atconfig.in'.
14488 And actually one diagram is missing: test suite runtime.
14490 2001-08-31 Akim Demaille <akim@epita.fr>
14492 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
14493 inverse order.
14495 2001-08-31 Akim Demaille <akim@epita.fr>
14497 * bin/autoupdate.in (@include): `installcheck' revealed the path
14498 to m4sugar was lacking!
14500 2001-08-31 Akim Demaille <akim@epita.fr>
14502 * man/Makefile.am (.x.1): We really have to pass
14503 autom4te_perllibdir.
14505 2001-08-31 Akim Demaille <akim@epita.fr>
14507 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

14509 run is stupid.
14511 2001-08-31 Akim Demaille <akim@epita.fr>
14513 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
14514 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
14515 Use directly autom4te, not autoconf.

14518 2001-08-31 Akim Demaille <akim@epita.fr>
14520 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

14530 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
14531 need for autoconf.
14532 Promote --include over --macrodir and other obsolete options.
14534 2001-08-31 Akim Demaille <akim@epita.fr>
14536 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

14538 * bin/autom4te.in ($autoconf): Pass --force.
14539 `print $out' doesn't print `$_' but `$out'.
14540 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
14541 (autoheader): Pass --force since the test suite goes too fast for
14542 the time stamps.
14543 Adjust to the new autoheader messages.
14545 2001-08-31 Akim Demaille <akim@epita.fr>
14547 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
14548 Check the completeness of the #template.

14557 Drop AC_MACRODIR dead for real.
14558 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14559 `autoheader: `config.hin' is created'.
14560 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14562 2001-08-31 Akim Demaille <akim@epita.fr>
14564 * bin/autoheader.in: Rewrite in Perl.
14565 * tests/autoheader: Adjust.
14567 2001-08-31 Akim Demaille <akim@epita.fr>
14569 * bin/autoconf.in (--include, -I): New option.
14570 Map --localdir, --autoconf-dir onto it.
14571 Forward autom4te's options instead of interpreting them.
14572 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14573 There is no such envvar since the inception of autom4te.cfg.
14574 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14575 * bin/autoupdate.in: Adjust, and perform more control.

14579 2001-08-31 Akim Demaille <akim@epita.fr>
14581 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
14582 * bin/autom4te.in (&find_file): Support `FILE?' standing for
14583 optionally `FILE'.
14584 Use -e, not -f, since /dev/null for instance is OK.
14585 (&parse_args): Adjust.
14586 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
14588 2001-08-31 Akim Demaille <akim@epita.fr>
14590 * configure.ac: Also find tested executables in bin.
14591 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
14592 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
14593 installed peer executables, only PATH is allowed to resolve it.
14594 Pass `autoconf_dir' via options, not via invisible envvars.
14595 * lib/Autom4te/General.pm (&find_peer): Remove.
14596 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14597 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14598 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14599 find the executables for it.
14600 * tests/Makefile.am: Major cleanup. Too lazy to document...
14601 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14602 We only need PERL.
14603 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14604 indeed related to running the test suite, while passing
14605 --autoconf-dir and others is related to running non installed
14606 Autoconf executables. So don't do that, leave it to...
14607 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14608 * tests/autoscan: New.
14609 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
14610 refer to library files: rely on --language.
14612 2001-08-29 Akim Demaille <akim@epita.fr>
14614 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

14617 2001-08-29 Akim Demaille <akim@epita.fr>

14623 2001-08-29 Akim Demaille <akim@epita.fr>
14625 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
14626 Suggested by Paul Eggert.
14628 2001-08-29 Akim Demaille <akim@epita.fr>
14630 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
14631 download in a tmp dir.
14633 2001-08-29 Akim Demaille <akim@epita.fr>
14635 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

14647 * bin/autoconf.in: Simplify and adjust.
14648 * tests/Makefile.am (AUTOMAKE): Use --set.
14649 * tests/atlocal.in: Adjust.
14650 * BUGS: distcheck and check are weak.
14652 2001-08-29 Akim Demaille <akim@epita.fr>
14654 * lib/autotest/general.m4: Use
14655 foo=`(command) 2>/dev/null`
14656 not
14657 foo=`command` 2>/dev/null
14658 (at-devnull): Rename as...
14659 (AT-devnull): this.
14660 (--clean): Remove AT-* files too.
14661 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
14662 Reported by Nicolas Joly.

14696 * lib/autotest/general.m4 (AT_INIT): Log the command line.
14697 Support `VAR=VAL' as arguments.

14717 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
14718 `ac_top_builddir' to mimic Automake's vocabulary, which much more
14719 readable.
14720 Adjust callers.
14721 * doc/autoconf.texi (Configuration Actions): Document the vars
14722 available in commands.
14723 Emphasize the risks of collisions in init-cmds.

15199 extension (needed on BeOS). Reported by Guido van Rossum.
15201 2001-08-09 Akim Demaille <akim@epita.fr>
15203 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15205 2001-08-07 Akim Demaille <akim@epita.fr>
15207 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15208 removed.
15209 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15210 No need to remove the files before and after the each test, before
15211 each test and at the end of the suite is enough.
15212 Display only the children `times', not the shell's.
15213 If the test failed or was skipped, at-times is not available.
15215 2001-08-07 Akim Demaille <akim@epita.fr>
15217 Always produce testsuite.log, including when there are no
15218 failures. This helps getting information on skipped tests, and
15219 duration of the tests. Err, implement the latter btw.
15221 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15222 Dump information on the first run of each test.
15223 (AT_CLEANUP): Create `at-times' containing the duration of the
15224 test group.
15226 2001-08-07 Akim Demaille <akim@epita.fr>
15228 The use of `dumpstat' revealed that `len' was used although it
15229 should not. m4_text_wrap was using it, but in the Autoconf world
15230 where it is legal. Hence (i) test M4sh in its own world, not
15231 Autoconf's, and (ii), ahem, fix the bug :)
15233 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15234 does not like `' instead of [].
15235 (AT_INIT): Forbid `^_?AT_'.
15236 And don't output such tokens.
15237 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15238 `script.as', and `autom4te.cache'.
15239 Remove `empty' and `macro' which are no longer used.
15240 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15241 * tests/m4sugar.at: Use it.
15242 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15244 2001-08-07 Akim Demaille <akim@epita.fr>
15246 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.

15250 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15252 2001-08-04 Akim Demaille <akim@epita.fr>
15254 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15255 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15256 AC_TRY_LINK.
15257 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15258 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15259 (AC_F77_MAIN): Likewise.
15261 2001-08-04 Akim Demaille <akim@epita.fr>
15263 Don't rely on M4sugar outputting the patterns in files, since we
15264 might process the output _without_ running m4, hence without these
15265 files.
15267 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15268 * bin/autom4te.in (@Request::includes): Remove, unused.
15269 (@Request::source): Rename as...
15270 (@Request::input): this.
15271 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15272 (&handle_output): Fetch the patterns from the traces.
15273 `$forbidden' and `$allowed' are constant: use m//o.
15274 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15275 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15277 2001-08-04 Akim Demaille <akim@epita.fr>
15279 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15280 autoconf', i.e., in addition to caching traces, cache the output.
15282 * bin/autom4te.in (Request::cache): Rename as...
15283 (Request::id): this.
15284 ($cache, $icache, $tcache, $ocache): New.
15285 (&handle_m4): Save M4 output in the cache instead of $tmp.

15288 (top level): Run `&handle_m4' iff force or the cache is invalid.
15289 Run `&handle_output' if the output cache is more recent.
15291 2001-08-04 Akim Demaille <akim@epita.fr>
15293 * bin/autom4te.in ($force): New.
15294 (&parse_args, &print_usage): -f, --force is a new option.
15295 (&handle_output): CPP directives might have spaces after `#'.
15296 (&parse_args): The first file only can be frozen.
15298 2001-08-04 Akim Demaille <akim@epita.fr>
15300 Don't let autom4te compute the `include' traces several times:
15301 first check that the trace cache file is up to date, and then
15302 compare its timestamp with that of the output.
15304 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15305 the preamble. Don't require 5.005 as Autom4te::General does it,
15306 and better yet (use `use', not `require'!).
15307 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15308 Class::Struct as Autom4te::Struct.
15309 * lib/Autom4te/General.pm (File::stat): Use it.
15310 (&mtime): New, export it.
15311 * bin/autom4te.in: Use it.
15312 Declare `$req' is invalid if it is outdated.
15313 Don't declare it valid before saving it if something went wrong.
15315 2001-08-04 Akim Demaille <akim@epita.fr>
15317 Autom4te shall not encode Autoconf data, and preselecting traces
15318 must be proposed to the users.
15320 * bin/autom4te.in (@required_trace): Remove.
15321 (@preselect): New.
15322 (&parse_args, &print_usage): -p, --preselect is a new option.

15324 * bin/autoconf.in: Preselect some Autoconf macros.
15326 2001-08-04 Akim Demaille <akim@epita.fr>
15328 * tests/tools.at (autoconf --trace: user macros): Check traces on
15329 macros invoked without arguments, and macros invoked with multiple
15330 lines arguments.
15332 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
15334 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
15335 arguments.
15337 2001-08-03 Akim Demaille <akim@epita.fr>
15339 * bin/autoconf.in ($@): Work around the usual sh bug.
15340 From Nicolas Joly.
15342 2001-08-03 Akim Demaille <akim@epita.fr>
15344 Clean up the handling of the M4 builtins tracing exception.
15346 * bin/autom4te.in (Request::request): Don't complete M4 builtins
15347 trace requests.
15348 (@m4_builtins): Rename as...
15349 (@m4_builtin): this.
15350 (%m4_builtin_alternate_name): New.

15352 (&handle_traces): Hence no longer do it here.
15353 (&trace_requests): Remove, unused.

15357 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,

15362 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
15363 (m4_divert_pop): Dump the whole diversion stack when a diversion
15364 mismatch happens.
15365 * bin/autom4te.in (&handle_output): Remember of the first
15366 occurrence of a possibly undefined macro, not the last.
15367 Complain about the possibly undefined macros in the same order as
15368 the appear in the output.
15369 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
15370 * tests/tools.at (autoconf: forbidden tokens, basic)

15372 autoconf's stderr, as it is now deterministic.
15373 Check that `dnl' is caught.
15375 2001-08-01 Akim Demaille <akim@epita.fr>
15377 * configure.ac: Bump to 2.52c.

15829 provide an alternate 'main' function name, using the 'main' from
15830 the Fortran libraries.
15831 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
15832 cross-language link tests can be performed successfully.
15833 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
15834 after $LIBS, for consistency; this should be the general rule since
