1139 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1141 <DEFAULTS>: Delay computation of variables based on $at_dir...
1142 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
1143 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
1144 <PARSE_ARGS>: Parse new option.
1145 <HELP_TUNING>: Document it.
1146 * tests/autotest.at (Choosing where testsuite is run): New test

1161 * doc/autoconf.texi (Particular Programs): Do not mention the
1162 Autoconf version in which the AC_PROG_INSTALL change was done.
1163 Suggested by Paul Eggert.
1165 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1167 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1168 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1169 mode, we change to the source directory, also set $ac_pwd so we
1170 do not go back to the build tree for the next config subdir.
1171 * tests/torture.at (Deep Package): Extend test to contain two
1172 config subdirs on the top level.

1228 Fix some whitespace tests on cygwin.
1229 * tests/tools.at (autom4te and whitespace in file names): Restore
1230 font-lock. Create $TMPDIR before it might be used.

1233 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1235 Optimize AC_REQUIRE.
1236 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1237 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1238 (m4_require): Avoid extra macro calls.
1240 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1242 * tests/torture.at (srcdir): Fix quoting.
1244 Do not pass top_srcdir to configure scripts in testsuite.
1245 * tests/autotest.at (srcdir propagation): Copy install-sh to
1247 (my only test): Drop setting of `top_srcdir'.
1248 * tests/base.at (Input/Output): Likewise.
1249 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1250 config.guess, and config.sub to test source tree.
1251 Drop AC_CONFIG_AUX_DIR setting.
1252 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1253 * tests/torture.at (Substitute a 2000-byte string): Drop
1254 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1255 (Substitute a newline, datarootdir workaround): Likewise.
1256 (Define a newline): Adjust for linenumber changes in configure.ac.
1257 * tests/foreign.at (Libtool): Adjust comment to reflect changes.

1264 * tests/tools.at (Syntax of the shell scripts): Likewise.
1266 * tests/m4sh.at (LINENO): Quote $0.
1268 Fix testsuite program wrapper for whitespace in `pwd`.
1269 The problem here is that the usual mantra is that command
1270 variables can contain arguments, thus we cannot just escape
1271 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1272 $top_builddir/tests directory early in $PATH, so that the
1273 wrappers are found by their plain name.
1274 * tests/wrapper.as: Put $testdir early in $PATH.
1275 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1277 Proper config.status --file/--header and $srcdir escaping.

1288 Quote $at_group_dir.
1289 * tests/autotest.at (whitespace in absolute testdir): New test.
1291 * lib/autom4te.in: Quote @datadir@.
1293 Proper file name escaping in Autoconf programs and Perl modules.
1294 This includes escaping of characters special to the shell
1295 as well as special to Perl, e.g., leading `<' or `>'.
1296 For example, when $file starts with `>', `open ">$file"'
1297 wrongly tries to append to a different file.
1298 * bin/autoconf.as: Fix quoting for autom4te options.
1299 * lib/Autom4te/General.pm (shell_quote): New function, taken
1300 from coreutils, written by Jim Meyering.
1302 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1304 * bin/autoreconf.in (parse_args): Likewise.

1308 * bin/ifnames.in: Likewise, XFile usage fixes.
1309 * tests/tools.at (autom4te and whitespace in file names): Extend
1310 test. Test twice, with special characters allowed on w32, and the
1311 rest. Test leading and trailing whitespace, for `open_quote'.
1312 (autotools and whitespace in file names): New, analogous test.
1313 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1314 by Russ Allbery and Eric Blake.
1317 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1318 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1319 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1320 (update_file, contents): Use it.
1322 * Makefile.am (autom4te-update): Rewrite for git.
1324 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1326 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1328 Fix copyright years.
1329 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1330 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1332 2007-12-04 Eric Blake <ebb9@byu.net>
1334 Manually resync with gnulib, since 'make cvs-update' no longer works.

1340 * doc/Makefile.am (TEXINFO_TEX): Add.
1342 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1344 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1345 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1346 #undef as this runs afoul of our new way of creating config.h.
1347 Problem reported by Jim Meyering in
1348 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
1350 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1352 Fix autom4te for unusual characters in input file names.
1353 * bin/autom4te.in (files_to_options): Quote active characters
1355 * tests/tools.at (autom4te and white space in file names):
1358 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1359 Document that Tru64 awk always splits $0.
1361 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1363 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1364 `#AT_STOP_...' line at the end of each test.
1366 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1368 * lib/autotest/general.m4 (AT_INIT): For awk line number
1369 extraction script, ensure `$at_group' has a defined value
1370 even for the empty set, and properly quote its usage inside
1373 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1375 * doc/autoconf.texi (Shell Functions): New chapter. Document
1376 IRIX sh $0 issue in functions, move content from ...
1377 (Portable Shell): ... here.
1378 (Shell Script Compiler): Note that shell functions are not
1379 totally unportable any more.
1381 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1382 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1384 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1385 extracting the line numbers of the last needed test.
1387 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1389 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1392 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1394 Fix IRIX testsuite debugging failures: $0 in functions.
1395 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1396 Do not use $0 inside a function, as IRIX sh will set that to the
1397 function name rather than the script invocation name.
1399 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1400 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1402 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1403 to extract test scripts.
1404 (AT_INIT): Extract and cache test script line numbers.
1406 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1408 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1409 subsequent fixups; the awk -> here-document conversion trashes
1410 performance too much with AIX sh.
1412 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1414 * tests/local.at: Do not test m4, perl with AT_TESTED.
1416 Diagnose and guard against write errors dealing with config.status.
1417 The general idea is this: all write failures from `configure'
1418 writing `config.status' are indicated by $ac_write_error, which
1419 is only checked at the end. This is safe because config.status
1420 code is not executed before the file is complete. Other write
1421 failures, be they inside config.status, or in sub shell/awk
1422 scripts spawned from configure or config.status, typically need
1423 earlier checking, as their results are used right afterwards.
1424 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1425 before writing config.status, check afterwards.
1426 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1427 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1428 Set `ac_write_error' for write failures to config.status. Barf
1429 upon write failures to temporary files.
1430 Adjust note about closing and reopening the here-document.
1431 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1432 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1433 reopening the here-document.
1434 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1435 Ensure `ac_write_error' does not escape into config.status.
1436 Also, add a couple of code paths not yet exercised in the test
1437 suite: a config file with input from stdin, and a config header
1439 Suggestion for catching write errors by Bruno Haible.
1441 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1443 Avoid error with Tru64 awk and testsuite lines with many words.
1444 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1445 reads the testsuite, set the field separator to an unusual value,
1446 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1447 even splits the input if $i, i>0, was never accessed in the script.
1449 Revert 2007-10-17 change.
1450 * TODO: Multiline args in config files and headers mean something
1451 different and are not fixed, see

1457 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1459 AC_*_TOOL does not canonicalize the prefix
1460 * doc/autoconf.texi (Generic Programs): Do not say that
1461 the *_TOOL macros canonicalize, they simply use the `host_alias'.

1465 Diagnose write errors in config.status instantiations.
1466 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)

1530 Adapt dependencies, now that a version change doesn't modify configure.ac
1531 * GNUmakefile: Remove "make clean" kludge.
1532 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1534 Don't redirect directly to target.
1535 Use $@, not literal "version.m4".
1537 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1539 * doc/autoconf.texi (Making testsuite Scripts): Document
1540 ":;{" shorthand as in previous patch.
1542 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1544 * doc/autoconf.texi (Limitations of Builtins): Document problem
1545 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1547 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1548 Use ":;{" shorthand.
1549 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1551 2007-11-12 Jim Meyering <meyering@redhat.com>
1553 Add more non-srcdir build support.
1554 * GNUmakefile (dummy): Split a long line.
1555 Add -v option to autoreconf invocation.
1557 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1558 * GNUmakefile (dummy): Remove INSTALL.
1560 Remove racy commands to build scripts in bin/ and tests/.
1561 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1562 are guaranteed to be built, remove the rules that tried to build
1563 them. Before, with a parallel build, these rules could lead to
1564 two processes writing tests/wrapper.in concurrently.
1566 Build in man/ only *after* building in bin/ and tests/.
1567 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1568 in both bin/ and tests/.
1570 Accommodate non-srcdir build-from-checkout.
1571 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1572 Use git's --git-dir=$srcdir/.git option.
1573 Add quotes, in case tarball_version_file contains shell meta-characters.
1574 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1575 * configure.ac: Pass "." to git-version-gen.
1577 Avoid spurious test failures due to version skew.
1578 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1580 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1582 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1583 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1584 Remove conftest.dSYM directory.
1585 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1586 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1587 Remove `conftest.*' recursively.
1588 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
1589 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1591 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
1593 Report and analysis by Jeff Squyres and Peter O'Gorman.
1595 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
1597 Fix typos in variable names.
1598 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
1600 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
1602 Document that $((expression)) is not portable.
1603 * doc/autoconf.texi (Shell Substitutions): Here.
1605 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1607 Ignore configure --help* errors due to LINENO-impaired shells.
1608 * tests/torture.at (Configuring subdirectories, Deep Package):
1609 In the --help* tests in read-only trees, make `.' temporarily
1610 writable again for the `stderr' file, and ignore errors due to
1611 the attempt to write configure.lineno.
1612 Report by Patrick Welche.
1614 2007-11-10 Jim Meyering <meyering@redhat.com>
1616 Generate package.m4 in build-dir, not srcdir.
1617 * tests/Makefile.am (package.m4): Adjust target.
1618 Don't redirect directly to $@.
1619 (CLEANFILES): Add package.m4.
1620 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1622 When running $(AUTOTEST), search "." before searching $(srcdir).
1624 Avoid a race condition that would make parallel "distclean" fail.
1625 * tests/Makefile.am (distclean-generic): Replace the default,
1626 automake-provided rule with an identical one, but with an additional
1627 dependency on distclean-local. Simply adding the dependency would
1628 cause automake not to emit the rule at all.
1629 * BUGS: Building with -jN works, now.
1631 Distribute git-version-gen.
1632 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1633 since GNUmakefile is distributed, and requires it for dist* rules.
1635 Remove two more generated files from version control.
1636 * INSTALL: Remove generated file.
1637 * lib/autoscan/autoscan.list: Remove generated file.
1639 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1641 * GNUmakefile (PATH): Remove stray apostrophes; they become
1642 part of PATH, which isn't wanted here.
1644 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1646 New config files output variable `top_build_prefix'.
1647 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1649 * doc/autoconf.texi (Preset Output Variables): Document it.
1651 Report by Bob Friesenhahn.
1653 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1654 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1655 function, to parametrize arithmetic with expr vs. the shell.
1656 Use it where possible.
1657 Suggestion by Benoit Sigoure.
1659 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1661 Adjust the documentation of autotest WRT atlocal.
1662 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1663 when using Automake, to write a rule to produce atlocal, since it's
1664 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1665 distributed, not atconfig.in.
1667 2007-11-04 Eric Blake <ebb9@byu.net>
1669 Update list information.
1670 * README: Mention new autoconf-commit list.
1671 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
1673 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1675 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
1677 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1679 * build-aux/.gitignore: Ignore mkinstalldirs.
1681 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1683 2007-11-03 Jim Meyering <meyering@redhat.com>
1685 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1686 * build-aux/git-version-gen: This syncs from coreutils.
1688 Adjust the build procedure so "make check" works reliably.
1689 * README-hacking: Include an extra step between "make" and
1690 "make check" to ensure that the latter passes.
1692 Use just-built tools, when possible.
1693 * GNUmakefile (PATH): Set and export here, ...
1694 (dummy): ... rather than here.
1696 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1697 and Andreas Schwab <schwab@suse.de>
1699 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
1702 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1704 * configure.ac (AC_PREREQ): Require version 2.60, for
1705 AC_PROG_SED, AC_PROG_GREP.
1707 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
1708 and Jim Meyering <meyering@redhat.com>

1712 Document a bug in GNU Bash with compound commands and redirections.
1713 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
1714 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
1717 2007-11-03 Eric Blake <ebb9@byu.net>
1719 Support m4 1.4.5 in testsuite.
1720 * tests/torture.at (Define a newline): Exclude line numbers in
1722 Reported by Ralf Wildenhues.
1724 2007-11-03 Jim Meyering <meyering@redhat.com>
1726 Remove automake-provided files from version control.
1727 * build-aux/elisp-comp: Remove file.
1728 * build-aux/install-sh: Remove file.
1729 * build-aux/missing: Remove file.
1730 * build-aux/mdate-sh: Remove file.
1731 * build-aux/.gitignore: New file.
1732 Suggestion from Ralf Wildenhues.
1734 2007-11-03 Eric Blake <ebb9@byu.net>
1736 Adjust version comparison to account for git snapshot numbers.
1737 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
1738 component separator.
1739 * doc/autoconf.texi (Number processing Macros)
1740 <m4_version_compare>: Document this change.
1741 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
1743 2007-10-30 Bruno Haible <bruno@clisp.org>
1745 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
1746 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1747 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1748 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1749 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1750 Suggested by Paul Eggert.
1752 2007-10-28 Jim Meyering <meyering@redhat.com>
1754 * README-hacking: Autoconf, Automake, and Perl are required to build.
1755 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1757 2007-10-28 Jim Meyering <meyering@redhat.com>
1759 README-hacking: Recommend running autoreconf -vi.
1760 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1761 so that we use just-built tools when they're available.
1762 Suggestions from Ralf Wildenhues.
1764 2007-10-28 Jim Meyering <meyering@redhat.com>
1766 Make inter-release --version output more useful.
1768 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1769 which indicates that it is built using the 19th change set
1770 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1771 is a prefix of the commit SHA1.
1772 * build-aux/git-version-gen: New file.
1773 * configure.ac: Run it to set the version.
1774 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1775 * Makefile.am (dist-hook): Arrange so that .version appears only
1776 in distribution tarballs, never in a checked-out repository.
1777 * .gitignore: Add .version here, too. Just in case.
1778 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1779 not configure.ac, now that the version number changes automatically.
1781 Ensure that $(VERSION) is up to date for dist-related targets.
1782 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1783 git-version-gen doesn't match $(VERSION), but only for dist targets.
1785 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1787 Fix `Deep Package' failure with a configure script early in PATH
1788 * tests/torture.at (Deep Package): Add `.' early in PATH.
1789 Report by Jim Meyering.
1791 2007-10-27 Jim Meyering <meyering@redhat.com>

1796 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
1797 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
1798 * README-hacking: New file: how to build from just-checked-out sources.
1800 2007-10-23 Eric Blake <ebb9@byu.net>
1802 Improve corner case of m4_expand.
1803 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more

1813 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1814 and Eric Blake <ebb9@byu.net>
1816 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
1817 problem reported by Bruno Haible in
1818 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
1820 2007-10-22 Eric Blake <ebb9@byu.net>
1822 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
1825 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1827 Don't check for bug in HP-UX 11.00 cpp.
1828 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
1829 Use -1ull rather than -1u, since that causes problems with gnulib; see
1830 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
1832 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1837 (Multiline parenthetical command substitution): Fix typos in
1840 2007-10-21 Eric Blake <ebb9@byu.net>
1842 * configure: Regenerate.
1844 2007-10-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1846 Fix config status generation with Tru64 ksh.

1848 escaping of backslash in here-documents.
1850 Fix `Deep Package' test failure on FreeBSD.
1851 * tests/torture.at (Deep Package): Do not add `.' to $PATH
1852 unnecessarily. Do not try running `/bin/sh configure' with a
1853 configure script to be found in $PATH, if the shell does not do
1854 this resolution. Fixes test failure on FreeBSD.
1856 Fix config header generation with AIX awk.
1857 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
1858 script, use helper array D_is_set, as `" 0"' does not evaluate
1859 to true for AIX awk.
1861 2007-10-21 Eric Blake <ebb9@byu.net>

1896 * lib/autotest/general.m4 (BANNERS): New named diversion.
1897 (TESTS_END): Diversion no longer used.
1898 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
1899 shell function, which prints only as needed, using an associative
1900 array of banner text from a special diversion.
1901 <PARSE_ARGS_END>: No longer need awk to find banners.
1902 <TESTS>: Banners are no longer processed by main driver loop, so
1903 we no longer need case statement.
1904 (AT_BANNER): Rewrite to populate new diversion.
1905 (AT_SETUP): Each test invokes its own banner. No output is needed
1906 to the TESTS diversion.

1933 duplication bug by using new macro.
1934 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
1935 programs with stdin redirected, so programs that don't
1936 understand --version won't try to behave interactively.
1937 * tests/autotest.at (Tested programs): Catch this bug.
1938 * tests/m4sugar.at (m4@&t@_append): Test new macro.

1999 will not actually be needed. Still try removing files, in case
2000 of other write errors.
2001 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): For ac_confdir,
2002 use $as_myself, not $0.
2003 (_AC_INIT_HELP): For --help=recursive, if the subdir does not
2004 exist, try again in the the source tree. This change assumes
2005 that the subpackage configure script is capable of running
2006 --help=recursive in the source tree.

3014 2007-05-02 Stepan Kasal <kasal@ucw.cz>
3016 * lib/autoconf/lang.m4, lib/autoconf/c.m4,
3017 lib/autoconf/fortran.m4, lib/autoconf/erlang.m4: Cleanup of
3018 section titles and other comments; no code change.
3020 2007-05-01 Kevin Ryde <user42@zip.com.au>
3022 * doc/autoconf.texi (Particular Programs): Typo
3023 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
3025 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
3027 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
3028 'configure' will fail if the shell lacks proper support for shell
3029 functions. Suggested by RMS.
3031 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
3033 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
3034 about Solaris /bin/printf '%010000x' 123. Problem reported by
3037 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
3039 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
3040 for a.* when searching for executables, as this prevents users
3041 from having files like a.c. Problem reported by Ralf Wildenhues in:
3042 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
3043 This fixes a problem introduced on 2000-12-19.

3047 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
3048 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
3051 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
3053 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
3054 AC_CHECK_TYPE, AC_CHECK_TYPES.
3055 * doc/autoconf.texi (Generic types): C types must be type-names
3056 (the C terminology), not type-ids (the C++ term). C++ types
3057 must not be anonymous.
3058 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
3059 for C++; this drops support for anonymous struct and union types,
3060 which were problematic anyway.
3061 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
3064 2007-04-12 Jim Meyering <jim@meyering.net>

3076 * doc/autoconf.texi (Generic Types): Document the restrictions
3077 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
3078 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
3079 with objects too. Document the restrictions on its use.
3080 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3081 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3082 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3083 works but the latter doesn't, then it's a valid type.
3084 This lets people use function types and so forth.
3085 For C++ there doesn't seem to be a simple solution, so leave it alone.
3086 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3087 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3088 AC_CHECK_TYPE; that wasn't documented or necessary.
3090 2007-04-11 Stepan Kasal <kasal@ucw.cz>
3092 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
3093 when cross-compiling.

3113 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
3114 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
3115 default still has the problem. Problem reported by Bruce Korb.

3130 command and case statements to make it a bit clearer and describe
3133 2007-03-23 Paul Eggert <eggert@cs.ucla.edu>
3135 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
3136 checks for unsigned long long int.
3138 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
3140 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
3141 nonstandard grep R.E. escape sequences.
3143 2007-03-17 Jim Meyering <jim@meyering.net>
3145 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3146 (Limitations of Usual Tools): Also list \< and \>, and mention that
3147 HP-UX's grep, like the one from Solaris, does not support that syntax.
3149 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3151 * doc/autoconf.texi (Specifying Names): `--host' does not
3152 change the build type.
3154 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3156 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
3157 suggests AC_CONFIG_HEADERS.
3158 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using

3168 universal binaries. Problem reported by Elias Pipping.
3170 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
3172 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
3173 * doc/autoconf.texi (C Compiler): Document this. There is a new
3174 extra argument ACTION-IF-UNIVERSAL.
3175 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
3176 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
3177 Reindent for sanity's sake.
3179 2007-02-24 Eric Blake <ebb9@byu.net>

3187 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3189 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
3190 status of rm so we know when it failed.
3191 If cleaning of test dir failed before running the test, warn.
3192 Output the line separator in verbose mode before the warning
3193 to make clear the warning belongs to the following test.
3195 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>

3220 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
3221 input from /dev/null in awk test, so even Solaris /usr/bin/awk

3258 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3259 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3260 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3261 substitution will still be done by the special code.
3262 Report by Jim Meyering.
3264 * doc/autoconf.texi (File System Conventions): Mention that
3265 $PATH_SEPARATOR is for the build system only.

3283 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3285 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3286 early on the reader side, drop stderr of the input to avoid
3287 `broken pipe' error output; this may happen even with shell
3288 builtin `echo' of some bash versions. Reports by Ian Macdonald
3289 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3291 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3304 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3305 * doc/autoconf.texi (Signed Overflow Examples): Give more
3306 discussion about the allow_superuser_privileges example,
3307 and change it a bit to make things clearer.
3308 (Optimization and Wraparound): Clarify whether the compiler
3309 will generate an infinite loop for the example derived from
3310 Autoconf's mktime test.
3311 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3312 Also, clarify unsigned multiplication overflow.
3314 2007-01-04 Eric Blake <ebb9@byu.net>
3316 * bin/Makefile.am (RELEASE_YEAR): New macro.
3317 (edit): Use it to supply correct copyright year to scripts.
3318 * bin/autoconf.as (version): Use it.
3319 * bin/autoheader.in ($version): Likewise.
3320 * bin/autom4te.in ($version): Likewise.
3321 * bin/autoreconf.in ($version): Likewise.
3322 * bin/autoscan.in ($version): Likewise.

3324 * bin/ifnames.in ($version): Likewise.
3326 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3328 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3329 feedback. The most important changes document what happens when
3330 you convert an out-of-range value to a signed integer type, and
3331 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3334 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3335 rewrite, taking notions from the recent discussion on the gcc and
3336 autoconf mailing lists; please see
3337 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3338 and follow the many links.
3339 (Integer Overflow Basics, Signed Overflow Examples):
3340 (Optimization and Wraparound, Signed Overflow Advice):
3341 (Signed Integer Division): New sections.
3343 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3345 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3346 preprocessor macro arguments in traced name.
3347 * doc/autoconf.texi (Defining symbols): Document longstanding
3348 support for AC_DEFINE-ing macros with arguments, and document
3349 behavior when the same variable has multiple AC_DEFINEs.
3350 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3351 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3352 macros directly, giving much shorter and simpler code.
3354 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3356 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3357 space before "$ac_configure_args" to prevent a 'config.status
3358 --recheck' failure if ac_configure_args doesn't contain a leading
3359 space. This works around a problem with the XEmacs configure.ac,
3360 which uses the (undocumented) ac_configure_args variable
3361 inconsistently with Autoconf.
3363 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3365 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3366 Include <limits.h>, and use its INT_MAX to rewrite the
3367 j loop so that it does not overflow 'int'. Problem reported by
3369 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3370 Play it safe by shifting left by 1 rather than multiplying by 2,
3371 as GCC is less likely to optimize this away when the value
3372 is signed (when it assumes overflow leads to undefined behavior).
3373 Also, don't assume time_t uses two's complement.
3375 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3377 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3378 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3379 dumps core on it. Report by Tim Rice.
3381 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3383 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about

3395 --enable-* and --with-* options.
3396 * doc/autoconf.texi (Option Checking): Renamed from
3397 (Configure Option Checking). Tighten up the wording a bit.
3398 (External Software, Package Options): Cross-reference to Option
3399 Checking, and use this to shorten our section.
3400 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3401 "$x" to test "x$foo" != x.
3402 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3403 Don't warn if $enable_option_checking is "no".
3404 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3405 ac_unrecognized_opts to the empty string.
3406 Don't echo the unrecognized opts, as this might mishandle
3407 backslashes or leading -.
3408 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3409 usage next to the other --disable-FEATURE options in the
3412 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3414 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3415 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3416 Print warning for unrecognized --with and --enable options
3417 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3418 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3419 Disable option checking when subdirs are configured.
3420 (AC_OUTPUT): If warnings are enabled, print warning about
3421 unrecognized --with and --enable options at the end of
3422 the configure output (as well as at the beginning).
3423 * doc/autoconf.texi (Option Checking): New node.
3424 Document new option warning functionality.
3426 2006-12-16 Eric Blake <ebb9@byu.net>

3429 * NEWS: Start news for current version.
3431 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3433 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3434 Define HAVE_GETMNTENT to 1, not to the empty string.
3435 Problem originally reported by Jochen Friedrich in
3436 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3438 This change prompted by a problem report by Andrey Simonenko in
3439 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3440 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3441 object-like macros only, in the traditional portable character
3443 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3444 Warn about attempts to define things that are not identifiers.
3445 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3446 awful hack that AC_DEFINEd macro names containing parentheses.
3448 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3450 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3451 too drastic, even if Texinfo in theory requires it for info mode.
3453 (config.status Invocation): Renamed back from Recreating a
3455 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3456 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3458 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>

3466 of limits on the total size of multi-line values of substituted
3467 variables, and the AC_FUNC_FSEEKO fix.
3469 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3471 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3472 Writing configure.ac.
3473 (Autoconf Input Layout): Renamed from configure.ac Layout.
3474 (Recreating a Configuration): Renamed from config.status Invocation.

3482 not to be a bug in the Autoconf build procedure itself, but rather
3483 a problem with the proprietary `make' programs.
3485 * doc/autoconf.texi (Build Directories): Add a cross reference

3492 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3493 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3494 generated automatically.
3496 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3498 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3499 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3500 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3502 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3504 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3505 `CEOF$ac_eof' special marker, the awk script cannot contain a
3506 line matching `^CEOF', so this is not needed any more.
3507 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3508 special marker in the test.
3510 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3512 * tests/tools.at (autom4te preselections): Use `find -newer';
3513 remove one of the sleeps.
3515 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3516 more readable, using ...
3517 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3519 * doc/autoconf.texi (autoheader Invocation): Do not double-
3520 quote the parameter of `AH_BOTTOM' in the example.
3522 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3524 * doc/autoconf.texi (Configuration Headers): Remove the
3525 example with multiple input files.
3526 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3527 multiple input files.
3529 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3531 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3532 creating the awk substitution script, handle one input line at a
3533 time, so that the maximum length of a substituted (multi-line)
3534 value is not limited by the size of the sed pattern space.
3535 The trade-off is a slightly repetitive sed script.
3536 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3537 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3538 * tests/torture.at (Substitute a 2000-byte string): Increase the
3539 test with several long lines, they should not be caught by sed
3542 * tests/tools.at (autom4te preselections): New test, to flag
3543 entries missing from autom4te.cfg.
3544 Report by David Byron <dbyron@hheld.com>.
3546 * tests/torture.at (Substitute a 2000-byte string): Actually use
3547 AC_PROG_AWK, so the last change works as intended.
3548 (Substitute and define special characters): Likewise.
3549 (Substitute a newline): Likewise.
3551 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3552 instead of `awk' consistently.
3553 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3554 * tests/torture.at (Torturing config.status): Test both the
3555 result of AC_PROG_AWK and plain awk.
3556 (Substitute a 2000-byte string): Likewise.
3557 (Substitute and define special characters): Likewise.
3558 (Substitute a newline): Likewise.
3560 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3562 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3563 can be assigned to a function pointer. Problem reported by
3564 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3565 part of a patch by Ralf Wildenhues in that same bug report.
3567 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3569 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3570 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3572 2006-12-01 Eric Blake <ebb9@byu.net>
3574 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3575 cross-compiling from cygwin to mingw.
3576 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3577 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3578 to lib/autoconf/c.m4.
3580 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3582 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3583 string for more reliable failure. Wrap the entire test that
3584 causes the broken Solaris printf to dump core, in a subshell,
3585 so the segmentation fault message is reliably suppressed.
3586 Fix shell expansion errors by using /usr/ucb/echo always;
3587 avoid an error on systems without it by another subshell.
3588 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3589 subshell-$as_echo to `as_echo', for better error message.
3591 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3593 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3594 `BASH_SOURCE' contain a newline, set them to empty, as they may
3597 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3599 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3600 years and is too hard to maintain now. The last straw was
3601 reported by Jerker Baeck in
3602 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3603 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3604 * doc/autoconf.texi (Particular Functions): Move
3605 AC_FUNC_SETVBUF_REVERSED from here...
3606 (Obsolete Macros): ... to here. Say that it does nothing now.
3607 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3608 Turn into (almost) a no-op.
3610 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3612 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3613 These macros are obsolescent and new applications shouldn't need them.
3614 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3615 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

3620 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3621 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3623 * doc/autoconf.texi (Setting Output Variables): Mention that
3624 @VAR1@VAR2 has unspecified behavior. Problem reported by
3626 * NEWS: Mention this.
3628 * Makefile.am: Put only a single '#' into the copyright notice,
3629 so that it's also present in the output file. Standardize wording
3630 in makefile copyright notices to match GNU coding standards.
3631 * bin/Makefile.am: Likewise.

3644 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3646 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3647 in the sed script that mangles the awk script: delete up to the
3648 first exclamation mark only.
3649 * tests/torture.at (Substitute and define special characters):
3652 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3654 Rewrite config files generation: avoid quadratic growth in
3655 the number of substituted variables by using awk instead of sed
3656 for the bulk of the substitutions.
3657 * NEWS: Mention this.
3658 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3659 forbidden in the output (and thus input) file.
3660 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3661 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3662 generate just one large awk script for substitutions,
3663 eliminating much of the earlier complexity, while adding some
3664 new complexity. Only expand the substitution templates at
3665 configure time, for smaller configure script size. If
3666 _AC_SUBST_FILES are used, test 'awk' for working getline support
3667 at config.status time. If absent, interpolate through the
3668 shell. The awk script was written with much help
3669 from Paolo Bonzini and Paul Eggert.
3670 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3671 (_AC_SED_FRAG_NUM): Likewise.
3672 (_AC_SUBST_CMDS): Renamed from...
3673 (_AC_SED_CMDS): ...this.
3674 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3675 * tests/torture.at (Substitute a 2000-byte string): Also
3676 substitute a line with 1000 words, and a variable with several
3678 (Substitute and define special characters): Test awk special
3679 characters, and put substitution input strings `@foo@' in the
3680 output, to test that no recursion happens; test several other
3681 combinations from Paolo Bonzini.
3683 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3685 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3686 that replaced echo with AS_ECHO where this wasn't necessary.
3687 Problem reportd by Ralf Wildenhues.
3688 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3689 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3690 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3692 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3694 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3696 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3698 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3699 that traditional Awk lacks 3-arg "split". It has it.
3700 Mention that FS must be a single character, and a few other
3701 99-byte limits of traditional Awk.
3702 Mention that if (i in a) doesn't work with traditional Awk.
3704 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3706 * tests/autotest.at (BSx641-newline in command):
3707 (BS-BS-newline in command, BSx640-newline in command):
3708 (Newline-CODE-BS-newline in command):
3709 (Single-quote-BS-newline in command):
3710 (Single-quote-newline-BS-newline in command):
3711 Use printf '%s\n' instead of echo, for portability to hosts
3712 where echo interprets backslashes. This will break on hosts
3713 that lack printf, but for now let's assume all such hosts
3714 are dead (if not, we should get reports of test failures).
3716 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3718 'echo' has some portability problems, when given a first argument
3719 with a leading '-', or when given any argument containing '\'.
3720 Avoid using 'echo' in these cases.
3721 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

3724 * lib/autotest/general.m4 (AT_INIT): Likewise.
3725 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the

3745 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3746 * bin/autoconf.as: Redo verbose flag implementation, as the old
3747 scheme wouldn't work with AS_ECHO.
3748 * lib/autotest/general.m4 (AT_INIT): Likewise.
3749 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3750 Don't use ECHO_T, since ECHO_N is now reliable.
3751 * lib/autotest/general.m4 (AT_INIT): Likewise.
3752 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3753 rather than using a here-document to put the script into a file.
3754 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3756 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3757 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3758 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3759 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3760 * lib/autotest/general.m4 (AT_SETUP): Likewise.

3762 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3763 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3764 operand, as AS_ECHO requires. Avoid double file name expansion.
3765 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3766 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3767 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3768 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3769 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3770 Double-quote strings that would otherwise contain M4 comments.
3771 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3773 * configure.ac (AC_INIT): Bump to 2.61a.
3776 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3780 * configure.ac (AC_INIT): Bump to 2.61.
3783 * tests/autotest.at (Macro with backslash in a test title):
3784 Comment out for now, as this tests neither fails nor passes
3785 reliably. Problem reported by Ralf Wildenhues.
3787 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3789 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
3790 in previous change, which caused test failures.

3802 Import these changes from config via gnulib:
3804 2006-11-15 Ben Elliston <bje@gnu.org>
3806 From Josselin Mouette <joss@debian.org>:

3859 first argument may also contain dots.
3861 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
3863 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
3864 benefit of platforms like Solaris+GCC where it is common to have a
3865 non-working g++ installation.

3872 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
3875 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3877 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
3878 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
3879 Imported from a similar patch to gnulib by Bruno Haible.
3881 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3883 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
3884 * doc/autoconf.texi (C Compiler): Document them.
3885 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
3886 New macros, taken from gnulib.

3894 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3896 * tests/torture.at (Configuring subdirectories): Do not skip
3897 Automake 1.10 nor future Automake 11.1 (sic).
3899 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
3900 and Stepan Kasal <kasal@ucw.cz>
3902 Handle special characters in test case titles correctly.
3903 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
3905 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
3906 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
3907 argument. Extend to check titles printed by ./micro-suite and
3908 ./micro-suite -l and the title in micro-suite.log.
3909 (Backquote in a test title,
3910 Single-quote in a test title,
3911 Double-quote in a test title): Don't expect failure anymore.
3912 (Backslash in a test title): Put a non-whitespace character after the
3913 backslash so that Bourne shells might actually see it as an escape
3915 (Brackets in a test title,
3916 Pound in a test title,
3917 Comma in a test title,
3918 Quoted Macro in a test title,

3921 (Macro with backquote in a test title,
3922 Macro with double-quote in a test title,
3923 Macro with backslash in a test title): New tests expected to fail.
3924 * tests/torture.at (#define header templates): M4-quote this title in
3925 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3926 The visible effect was a stray [] in the testsuite output.
3928 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3930 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3931 `trap ... 0' inside a function, for AIX sh.
3933 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3935 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3936 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build

3972 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3973 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3974 reported by Nelson H. F. Beebe for Coreutils 6.4.
3976 * tests/tools.at (autoconf --trace: user macros): Remove test
3977 for tracing multiline macros, since m4 1.4.7a uses a different
3978 way to number lines. Problem reported by Ralf Wildenhues.

4056 (Imported from Automake.)
4057 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4058 which incorrectly sets the mode of an existing destination
4059 directory. In some cases the unpatched install-sh could do the
4060 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4061 system. We hope this is rare in practice, but it's clearly worth
4062 fixing. Problem reported by Alex Unleashed in
4063 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4064 Also, don't bother to check for -m bugs unless we're using -m;

4114 added to the template can get mangled.
4116 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4118 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4119 include the default headers, and redefine obstack_chunk_alloc
4120 and obstack_chunk_free. Fixes false failure with glibc.

4137 the NonStop platform.
4138 * doc/autoconf.texi (Posix Variants): Likewise.
4139 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4141 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4142 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4143 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4144 Use a better substitute, by inspecting the output of "ls"
4145 rather than just using ":".
4146 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4147 rather than AS_EXECUTABLE_P, since we needn't worry about
4148 non-regular files here.
4150 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4151 due to configuration hassles with this. See Tonya Underwood's report

4164 initialization which is not inherited through the environment
4165 (_AS_BOURNE_COMPATIBLE): ... to this new macro.

4175 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4176 comment about ac_cpp_err; it was incorrect, and anyway
4177 ac_cpp_err is being removed below.
4178 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4179 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4180 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4182 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4183 with werror_flag and conftest.err and so forth. This is more
4184 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4185 and anyway the user shouldn't normally want to see this gorp logged.
4186 Problem reported by Ralf Wildenhues.
4187 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4188 empty, not 'no', since the rest of the code uses 'test -z'.

4192 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4193 Use a single call to AC_DO_TOKENS rather than multiple, for

4196 Problem reported by mwoehlke in
4197 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4199 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4200 than creating a file to use with test -x; this is much faster.
4202 2006-10-02 Bruno Haible <bruno@clisp.org>
4204 * lib/autom4te.in (Automake-preselections): Add
4205 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4207 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4209 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4210 standard error, `experr' should be used, not `expout'.

4214 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4215 fseeko testing program twice; just use the earlier result.
4216 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4217 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4218 still doesn't let the program compile.
4219 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4222 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4223 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4224 include it, without including anything else.
4225 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4227 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

4232 `error.h', and include it, for a `error_at_line' prototype.
4233 Use a nonempty format string in the link test.
4234 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,

4244 values. Problem reported by Ralf Wildenhues.

4406 except the first two arguments are reversed.

4419 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
4420 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
4421 programs should use their Gnulib counterparts.

4459 broken lex libraries like native ia64-hp-hpux11.22; see
4460 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4461 work around the problem by preferring an empty LEXLIB to -lfl or
4462 -ll. Let the user set LEXLIB='' to indicate no library needed.

4589 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
4590 -Wundef -Werror". Problem reported by David Fang in
4591 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

4611 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
4613 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
4614 problems with arg script text that doesn't end in newline, and

4617 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
4619 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

4651 less skeptical about "volatile", after discussion with
4652 Bruno Haible on bug-gnulib.

4663 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
4664 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
4666 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
4668 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
4669 after -R regardless of host. Patrick Welche reports that this
4670 fixes things on NetBSD 3.99.

4680 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
4681 under AC_C_VOLATILE.
4682 (Volatile Objects): Be a little less skeptical about what
4683 "volatile" means. Derived from thoughts by Ben Pfaff in
4684 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
4686 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4690 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4692 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4693 more globally, since the 2006-06-30 patch didn't suffice. Problem
4694 reported by Keith Marshall. Also, don't bother with builddir2,
4695 since it shouldn't be needed any more.
4697 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
4699 * doc/autoconf.texi (Generic compiler characteristics):
4700 Document AC_COMPUTE_INT. Fix wrong statements on Default
4701 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
4703 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.

4714 * NEWS: Document previous change.
4716 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4718 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4719 Require that long long int be at least 64 bits wide. C99 requires
4720 this and enough programs depend on it so we should check for it.
4721 Bruno Haible reports in
4722 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4723 that long long int is 32 bits wide with some nonstandard compilers.
4724 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.

4728 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4729 to a nonexistent file, so that we don't have to worry about
4730 a local site configuration that doesn't use /usr/local.
4731 Problem reported by Keith Marshall in
4732 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4734 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4736 * doc/autoconf.texi: Be more consistent about using @acronym with
4737 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4738 quite right (it talked about "OSF/Tru64", even though the
4739 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4740 and it even mentioned "OSF 4"!) and at this point there's little
4741 reason to talk about OSF any more, since it died in 1994.
4742 (Specific Compiler Characteristics): Simplify example of
4743 negative-size array.
4744 (File Descriptors): Reorder to make the text flow better.
4745 Remove joke about "appreciate the various levels"; I didn't get it.
4746 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4747 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4748 (File Descriptors, Limitations of Usual Tools):
4749 Tone down the advice against renaming or removing open files.
4750 (Limitations of Usual Tools): Add a new section, on 'rm'.
4752 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4754 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4755 -lXt in LIBS, idea from Karsten Hopp; this was due since
4758 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4759 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4760 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4761 (which belong to Xt, not X itself). See Debian bug 327655.
4763 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4765 * configure.ac (AC_INIT): Bump to 2.60a.
4768 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4772 * configure.ac, NEWS: Update.

4785 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4787 * doc/autoconf.texi (Changed Directory Variables): New node,
4788 to document the whole `datarootdir' business a bit better.
4790 * tests/torture.at (datarootdir workaround): Extend test.
4791 Prompted by report by Alexandre Julliard.
4793 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4795 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4796 when using default mode of IBM C 6 for AIX. Problem and two-line
4797 fix reported by Larry Jones.
4799 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4801 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4802 about literal '${datarootdir}' if a definition is found in the
4805 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4807 * NEWS: Use "M4" rather than "m4" when appropriate.
4808 Problem reported by Eric Blake.
4809 * doc/autoconf.texi: Likewise.
4810 Use @acronym around BSD, GCC, and GNU when appropriate.
4811 (Why GNU M4): Renamed from "Why GNU m4".
4812 (Redefined M4 Macros): Mention that Posix
4813 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4814 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4817 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4819 * bin/autom4te.in (handle_output): Do not forbid the empty
4821 * tests/tools.at (autoconf: the empty token): New test.
4823 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4825 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4826 calls, so that we do not care whether they are LIFO or FIFO;
4827 in the m4_wrap, do not check which diversion is the topmost
4828 one, just check that the stack is balanced at the end.
4829 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4830 base diversion forever--pop the previous diversion before
4831 opening the new one; consequently, remove the m4_wrap call.
4832 * lib/autotest/general.m4 (AT_INIT): Likewise.
4833 * tests/m4sugar.at: Do not use
4834 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

4837 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4839 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4840 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4841 Rework example of m4wrap token-pasting trouble so that it doesn't
4842 care whether it's LIFO or FIFO.
4843 Fix some "contrary to"s that are awkward in English.
4845 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4847 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4848 to `yes' instead of `int$1_t' if the type is found, for more
4849 consistent configure output (where $1 is the number of bits).
4850 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4851 Suggested by Bruno Haible.
4853 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4854 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4855 with system headers. Report by Bruno Haible.
4857 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4859 * config/config.guess, config/config.sub: Sync from upstream.
4861 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4862 in order to avoid picking up an older installed frozen m4sh.m4f.
4863 Besides an outdated shell startup, this could have been created
4864 by an earlier M4 version with incompatible frozen file format.
4866 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4868 * README: Recommend m4 1.4.4 instead of 1.4.3..
4869 * doc/autoconf.texi: Likewise.
4870 (Special Chars in Names): Say that $(.FOO) is portable, as
4871 suggested by Stepan Kasal.
4872 (Installation Directory Variables, Build Directories):
4873 (Automatic Remaking, Subdirectories, Fortran Compiler):
4874 (Making testsuite Scripts, Defining Directories):
4875 Quote variable usages better.
4876 (Making testsuite Scripts): Add clean-local rule to makefile
4877 snippet, by Eric Blake.
4878 (Installation Directory Variables): Fix table item font.
4879 Reword slightly to clarify. Generalize advice about
4880 not using special characters to include all file-related
4881 vars, not just VPATH.
4882 (Special Chars in Variables): Warn about special characters in
4884 (Assignments): Clarify default-value example as suggested by
4886 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4887 (Special Shell Variables): Note leading ./ or ../, as suggested
4889 (Limitations of Builtins): Under cd, warn about CDPATH.
4890 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4893 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4895 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4896 `@var', for texi2html.
4897 (Systemology): Some more word wrapping, for DVI output.
4898 (autom4te Invocation): The short option for `--melt' is `-M',
4901 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4903 * doc/autoconf.texi: More formatting and English tweaks,
4904 many suggested by Ralf Wildenhues.
4905 Reword to avoid "@code{...}'s" and the like, since it's ugly
4906 with Emacs info mode. discontents -> woes.
4907 Put a few "will"s back. time stamp -> timestamp.
4908 side-effect -> side effect.
4910 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4912 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4913 Warn about $@ not persisting. Problem reported by Julien Danjou in
4914 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4915 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4916 Mention other special chars, too.
4918 2006-06-14 Eric Blake <ebb9@byu.net>
4920 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4922 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4924 * doc/autoconf.texi: Some systematic minor improvements, as
4925 follows. Use "makefile" when talking about makefiles
4926 generally (which might be named "makefile" or "Makefile" or even
4927 "foo.mk"), "Makefile" when talking about a specific makefile
4928 called "Makefile". This unclutters the text from weird quotes
4929 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4930 values" rather than "@var{foo}s" and similar constructs containing
4931 "}s". Use "Make rules" rather than "Makefile rules". Minor
4932 English-language improvements. Change the prefix "sub-" to "sub"
4934 Put blank lines around examples more consistently.
4935 Avoid "rather" and "very" as intensifiers.
4936 Avoid "will" as an auxiliary.
4937 (Limitations of Make): Split this node into....
4938 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4939 (Leading _ in Macro Names, Backslash-Newline-Newline):
4940 (Backslash-Newline Comments, Long Lines in Makefiles):
4941 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4942 (obj/ and Make, make -k Status, VPATH and Make):
4943 (VPATH and Double-colon, $< in Explicit Rules):
4944 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4945 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4946 New nodes, resulting from splitup of Limitations of Make.
4947 All cross-references changed. Raise the top node from
4948 a section to a chapter, and all subnodes accordingly.
4949 Redo the introductory wording to match the new organization.
4950 (Installation Directory Variables): Use an example that is
4951 closer to what Autoconf actually does. Mention that VPATH's
4952 value should not contain metacharacters or white space.
4953 (Fortran Compiler): Fix a VPATH bug in an example.
4954 (Leading _ in Macro Names): Mention that this problem is no longer
4955 of practical concern.
4956 (VPATH and Make): Reword the advice to make it clearer
4957 that Autoconf and Automake support VPATH in non-GNU make, but
4958 many packages have bugs in this area.
4959 ($< in Explicit Rules): Refer to Build Directories rather
4960 than using a (non-VPATH-safe) example.
4961 (Automatic Rule Rewriting): Mention the sort of disaster that
4962 can ensue with Solaris-style rule rewriting with VPATH.
4964 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4966 * doc/install.texi (Compilers and Options): Weaken the
4967 suggestion to use GNU make for VPATH builds.
4969 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4970 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4972 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4973 in regular expression.
4975 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4977 * doc/autoconf.texi (Installation Directory Variables):
4978 Drop extra @samp from `@table @samp' item.
4979 (Limitations of Usual Tools): Comment fix.
4980 Do not nest @samp just to point to other table items.
4981 (Writing testsuite.at) <AT_CHECK>: The second argument to
4982 `@dvar' is already @samp'ed.
4983 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4984 do not use @var in the second argument.
4986 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4988 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4989 $as_shell.exe too. Problem reported by Andreas Buening in
4990 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4992 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4994 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4995 `unused variable' compiler warning, for `-Wall -Werror'.
4996 Reported by Jaap Haitsma in
4997 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4999 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5001 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5002 case the compiler dumps core. Problem reported for
5003 OpenServer 5.0.7 by Tim Rice in
5004 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5005 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5008 2006-06-06 Tim Rice <tim@multitalents.net>.
5010 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5011 "ERROR" only shows up in "make check" output if there is an
5014 2006-06-06 Eric Blake <ebb9@byu.net>
5016 * tests/tools.at (automatically allowed tokens): Fix typo.
5018 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5020 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5022 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5023 typically overflows on x86 CPUs, even though the C standard
5026 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5028 * configure.ac (AC_INIT): Bump to 2.59e.

5035 * config/texinfo.tex: Sync from upstream.
5037 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5038 seen, invoke libtoolize with `--ltdl' argument.
5039 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5041 Suggested by Eric Blake.
5043 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5045 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5046 reported by Ralf Wildenhues.
5047 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
5049 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5053 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5055 * doc/autoconf.texi: Modernize some of the references to Solaris.
5057 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5059 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5060 message issued by AC_REQUIRE.
5061 * tests/m4sugar.at: Check m4_require's error message.
5062 * tests/base.at: Check AC_REQUIRE's error message.
5063 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5065 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5067 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5068 `expout' as the last parameter.
5069 * tests/tools.at: Adapt to the above change.
5071 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5073 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5074 information about race-free implementations of mkdir.
5076 2006-06-04 Eric Blake <ebb9@byu.net>
5078 * bin/autoreconf.in (help): Document M4 environment variable.

5081 * doc/autoconf.texi (autom4te Invocation): Likewise.
5083 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5085 * NEWS: GNU make now recommended for VPATH builds.
5086 Mention that some macros are now documented to be obsolescent.
5087 * doc/autoconf.texi:
5088 Prefer "current" to "modern" to describe
5089 currently-used (albeit perhaps old-fashioned) hosts.
5090 Mention which ancient features no longer need to be worried about.
5091 setgid -> set-group-ID
5092 setuid -> set-user-ID (these are the Posix terms)
5093 Fix some misuses of "only".
5094 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5095 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5096 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5097 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

5103 Mention that these macros are obsolescent.
5104 (Installation Directory Variables): shall -> should
5105 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5106 Mention that it's now safe to use 3 and 4.
5107 (Limitations of Usual Tools): cp -r is now specified by Posix.
5108 Omit longwinded and obsolescent discussion of cp -f.
5109 Modernize discussion of expr, ls.
5110 (Limitations of Make): Modernize discussion of VPATH builds.
5111 Mention $? as a workaround in some cases.
5112 * doc/install.texi (Basic Installation):
5113 Mention "./configure; make; make install" first. Be more
5114 specific about why this file is generic. Remove unnecessary
5115 parens. Remove misleading "only". Remove obsolete advice
5116 about csh. Don't say "configure" takes awhile; say it
5117 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5118 and CC=c99 rather than CC=c89, as these are blessed by current
5119 Posix. Recommend GNU make if doing a VPATH build.
5121 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5123 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5124 examples involving shell prompts.
5126 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5127 and Paul Eggert <eggert@cs.ucla.edu>
5129 * doc/autoconf.texi (Here-Documents): Add details about the
5130 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5131 use "here-documents" instead of "here documents".
5133 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5135 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5137 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5139 * doc/autoconf.texi (File System Conventions): Warn about ":"
5140 anywhere in directory names.
5142 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5144 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5145 about quoting the case statement, just in case.
5146 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5147 was fixed in ksh93g; reported by Ralf Wildenhues.
5149 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5151 * doc/autoconf.texi (System Services): Do not document
5152 overriding EXEEXT via ac_cv_exeext=ext.
5153 (Particular Programs) <AC_PROG_MKDIR_P>:
5154 Document that ${MKDIR_P} understands --.

5158 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5160 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5161 argument with leading hyphen. Problem reported by Paul Eggert.
5163 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5165 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5166 about quoting ac_try: quote all of it, if any of it seems suspicious.
5167 This means we don't have to worry about ${ or sed any more.
5168 Also, double-quote the case statement, to work around misuses via
5169 underquoting as reported by Ralf Wildenhues in
5170 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5171 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5172 undocumented and dangerous macro.
5173 Problem reported by Ralf Wildenhues in
5174 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5176 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5179 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5180 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5182 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5184 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5185 since evidently some packages rely on the old, broken behavior.
5186 Problem reported by Ralf Wildenhues in
5187 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5188 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5189 pre-2006-05-26 definitions, but leave in the comments that
5190 these macros are dangerous and should not be used.
5191 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5192 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5193 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5194 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5195 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5197 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5199 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5200 the use of 'tr', since this is our only use of 'tr'.
5202 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5203 and Paul Eggert <eggert@cs.ucla.edu>
5205 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5206 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5208 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5210 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5211 the output file in the `${datarootdir}' test.
5213 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5214 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5216 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5217 mention of `datarootdir' in the input file(s), but literal
5218 `${datarootdir}' in the output file, and we haven't warned yet,
5219 then warn as well: the user may have (erroneously) used
5220 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5221 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5222 * tests/torture.at (datarootdir workaround): Extend this test.
5225 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5226 and Paul Eggert <eggert@cs.ucla.edu>
5228 * doc/autoconf.texi (autoheader Invocation): The first argument to
5229 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5230 alternatives and clear up the language a bit.
5232 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5234 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5235 ac_config_guess, ac_config_sub, ac_configure.
5236 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5237 Fix typo that prevented an unnecessary space from being removed.
5238 Problems reported by Ralf Wildenhues in:
5239 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5241 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5243 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5244 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5245 Don't use the term "thread-safe" to talk about mkdir race
5246 conditions, since the problem is more a process than a thread
5247 issue. Problem reported by Stepan Kasal in:
5248 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5249 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5250 the test for 'install' more closely. Look at MKDIR_P first.
5251 Look in the PATH, and at /opt/sfw/bin.
5252 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5253 Don't bother to try mkdir -p, since we already check mkdir --version;
5254 just look at the version number. (There's no easy way to check
5255 for race-free implementations.)
5256 * tests/tools.at (autoconf: subdirectories): Adjust to above
5257 changes, since MKDIR_P now might end in "/mkdir -p".
5259 * doc/autoconf.texi (autoheader Invocation): Mention that the
5260 first arg of AC_DEFINE_UNQUOTED must be a literal.
5261 Problem reported by Ben Pfaff in
5262 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5264 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5265 * doc/autoconf.texi (Special Chars in Variables): New section.
5266 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5267 (Installation Directory Variables): Quote $(datadir) better.
5268 (Limitations of Builtins): Describe some of eval's trickiness.
5270 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5271 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5272 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5273 in front of every arg, not just trailing args. Quote apostrophes.
5274 (_AC_EVAL_ECHO): New macro.
5275 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5276 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5278 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5279 exposed by quoting of eval argument. Put the command on line line
5281 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5282 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5283 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5284 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5285 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5286 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5287 Use eval more safely.
5288 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5289 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5291 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5292 lines, exposed by quoting of eval argument.

5295 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5297 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5298 initialization of `ac_cv_exeext', do not override it if it was
5299 already set, unless it was set to `no', for compatibility with
5300 Autoconf-2.13, and comment this.
5301 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5302 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5303 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.

5319 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5320 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5321 ac_file to the name of the default output file and call
5322 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5323 initial `rm' of the candidate files...
5324 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5325 the same list in subsequent `rm' calls, and for the temporary
5326 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5327 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5328 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5329 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5330 no longer needed) by libtool. Make it a cache check.
5331 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5332 copied here by mistake.
5333 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5334 _AC_COMPILER_EXEEXT.
5335 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5336 _AC_COMPILER_OBJEXT directly.
5337 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5339 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5341 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5342 Fix description of how the buggy `sed' works.
5344 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5348 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5349 ENOLCK. Only mention `make -j' when applicable. Only raise
5350 fatal errors when `make -j' is involved. Improve error message.
5352 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5354 * doc/autoconf.texi (Here-Documents): We now know more about
5355 the variable expansion in here documents bug.
5356 Thanks to Tim Rice and Stepan Kasal.
5358 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5359 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5361 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5363 * tests/autotest.at (Multiline command from M4 expansion):
5364 No failure to be expected if the shell quotes newlines in
5365 commands in the `set -x' output. Report by Tim Rice.
5368 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5370 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5371 expansion in the here-documents used by config.status, as that
5372 runs afoul of the Korn shell version M-12/28/93d bug described in
5373 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5374 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5375 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5377 2006-05-23 Jim Meyering <jim@meyering.net>
5379 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5380 Fix typo introduced with 2006-04-02 change. It reversed the sense
5383 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5385 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5386 ac_dB slightly, to save bytes in the script.
5387 Max out at 50 lines, rather than 96; this is more likely
5388 (though not guaranteed) to avoid obscure 'sed' failures.
5390 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5392 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5393 `tr -d -' as bad option argument. Work around this by deleting
5394 an unrelated character.
5395 Report by Tim Rice <tim@multitalents.net>.
5397 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5398 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5399 Stepan Kasal <kasal@ucw.cz>
5401 * doc/autoconf.texi (Particular Programs): Do not promise that
5402 we always prefer the GNU version of the program, and that we
5403 search according to PATH; both rules can have exceptions.
5404 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5405 AC_PROG_SED. Move descriptions of limitations
5406 to the Limitations of Usual Tools section.
5407 (Limitations of Usual Tools) <sed>: Mention script length
5408 limitations with Solaris /usr/ucb/sed.
5409 <grep>: Fix wording for empty alternative. Mention that -c and
5410 -l should not be combined, and that -E and -F should not be
5413 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5414 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5416 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5417 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5419 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5421 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5422 AC_DEFINE is now passed to m4_pattern_allow.
5423 * NEWS: Mention that; likewise for AC_SUBST.
5424 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5425 the parameter to m4_pattern_allow.
5426 * tests/tools.at: Add a check for that.
5428 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5430 * lib/autoconf/status.m4: Fix typos.
5432 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5434 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5435 only the files that this macro generates.
5437 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5439 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5440 the HP-UX sed limitation of 99 commands, labels do not count.
5441 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5443 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5445 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5447 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5448 Import the following fix from coreutils:
5450 2006-01-13 Jim Meyering <jim@meyering.net>
5452 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5453 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5454 not double-quote uses of that variable, to accommodate the rare
5455 case in which getmntent is available in none of the libraries
5456 checked. This happens at least on FreeBSD 5.0.
5458 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5460 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5461 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5462 some other programs unwisely rely on these undocumented vars.
5463 But put in warning comments about them.
5464 Problem reported by Ralf Wildenhues in
5465 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5466 * NEWS: Document that these variables are intended to go away.
5468 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5470 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5471 and set the language to C++ (analogous to the equivalent Fortran
5474 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5475 * doc/autoconf.texi (C++ Compiler): Document it.
5476 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5479 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5481 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5482 that caused config.status to generate 100-command sed scripts; the
5483 portable limit is 99.
5485 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5487 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5488 variable `ac_d' instead of `d' to avoid infringing namespace.
5489 Report by Ralf Menzel.
5491 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5493 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5494 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5495 * tests/tools.at (autoconf: subdirectories): New test, taken from
5496 the corresponding problem report by Ralf Wildenhues in:
5497 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5499 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5500 Quote some uses of shell variables if they might suffer unexpected
5501 globbing. This doesn't fix all instances of quoting problems that
5502 I found, just the easy ones that look safe.
5503 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5504 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5505 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5506 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5507 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5508 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5509 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5511 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5512 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5514 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5516 * bin/autoreconf.in ($help): Reword according to the manual.
5517 Suggested by Olly Betts.
5519 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5520 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5522 * bin/autoreconf.in: Pass the directory argument to
5523 `require_configure_ac'. Fix comment.
5524 * tests/torture.at (Configuring subdirectories): Expose this.
5525 Reported by Olly Betts.
5527 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5529 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5530 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5531 Automake as follows:
5533 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5534 `$configure_in' instead of `configure.in', to preserve
5535 directory component.
5537 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5539 * config/config.guess, config/config.sub, config/texinfo.tex,
5540 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5542 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5544 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5545 test for C99 conformance; (bool) 0.5 is an integer constant
5546 expression, but (bool) -0.5 is not. Problem reported by Fedor
5547 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5549 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5551 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5552 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5553 Warn about obsolete install-sh files. Remove stray sentence
5554 fragment and fix cross reference.
5555 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5556 install -d; this undoes the 2006-05-10 change.
5557 (MKDIR_P): Mark with AN_MAKEVAR.
5558 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5559 that we don't require $INSTALL to be thread-safe. Move comments
5560 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5561 of AC_PROG_INSTALL. Output a message saying that we're checking
5562 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5563 MKDIR_P instead of AC_SUBST.
5564 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5565 Special magic for MKDIR_P, too.
5566 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5568 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5570 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5572 Sync from Automake, as follows:
5574 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5575 * config/install-sh: Initialize IFS, so field splitting isn't
5577 * config/mkinstalldirs: Likewise.
5578 * config/missing: Remove superfluous quotes. Replace all uses of
5579 `[' by `test', for consistency, and for..
5580 * config/missing (sed_minuso, sed_output): New variables.
5581 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5582 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5583 Fixes `missing' to detect `--output' for help2man. Fixes
5584 PR automake/483. Report by Dennis J. Linse.
5585 (autom4te): Document in `missing --help'.
5587 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5589 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5590 * config/install-sh: Don't use 'path' to talk about file names,
5591 as per GNU coding standards. Close a race condition reported by Ralf
5592 Wildenhues and Stepan Kasal. There is still a race condition
5593 on hosts that predate Posix 1003.1-1992, but we can't help this.
5594 Don't mishandle weird characters like space on pre-Posix hosts.
5595 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5596 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5597 AC_PROG_MKDIR_P from AS_MKDIR_P.
5598 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5599 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5600 earlier editions are not (including Automake 1.8.3).
5601 Do not suggest mkinstalldirs for thread-safety.
5602 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5603 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5604 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5605 presence of special characters and race conditions.
5606 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5607 in Autoconf's name space.
5609 2006-05-10 Bruno Haible <bruno@clisp.org>
5610 and Paul Eggert <eggert@cs.ucla.edu>
5612 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5613 from Automake with minor changes.
5614 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5616 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5618 * config/install-sh: Update to Automake CVS version, as follows:
5619 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5620 * lib/install-sh: Simplify the expr implementation of dirname.
5621 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5622 * lib/install-sh: Handle --, and diagnose unknown options.
5624 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5626 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5627 `./autom4te' to create `./testsuite', since the `all' target
5628 will ensure its presence, but `installcheck' should not create
5629 the uninstalled wrappers.
5631 * tests/torture.at (Unusual Automake input files): Skip if we
5632 detect automake < 1.8.
5634 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5636 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5637 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5638 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5641 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5643 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5644 munge (multiple) white space and other oddities.
5645 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5646 single quotes in variable assignment.
5647 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5648 and similar failures by adding multiple spaces, tabs, and other
5650 Report and different test suggested by Francesco Romani
5651 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5653 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5654 single quotes, we only need to search for single quotes; this
5655 both simplifies the search pattern, and makes us less
5656 susceptible to `echo' variations for arguments not containing
5658 (_AC_ARG_VAR_VALIDATE): Likewise.
5660 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5662 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5663 `$*' and IFS concatenation issue with traditional shells and
5664 bash-2.04. Report by Seanster@Seanster.com.
5666 2006-05-03 Bruno Haible <bruno@clisp.org>
5668 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5669 precisely which Mac OS X versions have the od problem.
5671 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5673 * doc/autoconf.texi: Use @option systematically.
5675 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5676 and Bruno Haible <bruno@clisp.org>
5678 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5680 (Integer Overflow): Mention the special case of integer division
5683 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5685 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5686 traditional shells like the Solaris one that do not use the
5687 first IFS character for assembling `$*'.
5688 Prompted by a related report from autoconf_bug@nro.ca.
5690 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5691 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5693 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5694 Mention more problems with the -e option.
5696 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5699 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5701 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5702 in URLs to improve DVI formatted output (requires texinfo 4.6).
5703 (System Services, Systemology, Shellology): Likewise.
5704 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5707 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5709 (Runtime): Fix macro argument names to match description:
5710 `action-if-found' -> `action-if-true' and similarly.
5711 (Obsolete Macros): Likewise.
5712 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5713 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5714 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5716 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5718 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5721 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

5726 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
5727 /bin/sh set unsorted output.

5736 (Writing Test Programs): Fix some langauge. Recommend exiting
5737 with status 1, not merely nonzero. Clarify exit declaration.

5744 * bin/autoconf.as (me): Replace by as_me.
5746 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5748 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5749 since as_me isn't set yet.
5751 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5753 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5754 a few minor bugs in this area.
5756 * doc/autoconf.texi (Programming in M4sh): Comment out the
5757 documentation of AS_BASENAME, for now.
5758 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5759 (Limitations of Builtins) <basename>: Do not refer to

5771 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
5772 (_AS_DIRNAME_PREPARE): Likewise.
5773 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
5774 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5775 (AS_DIRNAME): Use "dirname --".
5777 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5779 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5780 of "run time" and "run-time" changed to "runtime", for consistency.
5781 * lib/autoconf/fortran.m4: Likewise (in comment).
5782 * lib/autoconf/functions.m4: Likewise.
5783 * lib/autoconf/general.m4: Likewise.
5784 * lib/autoconf/headers.m4: Likewise.
5786 * doc/autoconf.texi (Run Time): Document the exit status situation
5787 with more accuracy and detail.
5789 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5791 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5792 Archive is not officially `GNU' any more. Update URL.
5793 (Defining Directories): Likewise
5794 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5796 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5798 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5799 newline from the `trap' code to finish `config.log'; the NetBSD
5800 /bin/sh resets the exit status after an empty command, as
5801 documented in doc/autoconf.texi.
5802 Reported by Dalibor Topic <robilad@kaffe.org>.
5804 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5806 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5807 Suggested by Bruno Haible.
5809 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5811 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5812 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5813 Instead, just list the shells that we know work.
5814 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5815 changed. Be more cautious about the _cv_ variable.
5816 * tests/tools.at (Syntax of the shell scripts): Check the
5817 _cv_ variable once, at first, to avoid an internal autoconf error
5818 when sh -n does not work.
5820 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5822 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5824 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5826 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5827 use ">&-" since we're only 99.999% sure that this is portable,
5828 and since the MinGW bug is fixed in a different way.
5829 * lib/autotest/general.m4 (AT_INIT): Likewise.
5831 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5833 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5834 before opening config.log, to avoid hitting a bug on MinGW.
5836 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5838 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5839 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5840 This works around a MinGW bug reported by Eric Paire.
5841 Make sure that all writes to the log file append to it,
5842 rather than possibly losing data.
5843 * lib/autotest/general.m4 (AT_INIT): Likewise.
5845 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5847 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5850 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5854 * configure.ac (AC_INIT): Bump to 2.59d.
5856 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5860 * Makefile.maint (news-date-check): Do not require a leading `*'
5861 before the release date in NEWS.
5863 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5864 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5866 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5867 the instantiated file do not contain the string 'datarootdir'
5868 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5869 @mandir@, replace the reference '${datarootdir}' by the value.
5870 * tests/torture.at (datarootdir workaround): New test.
5871 * NEWS: Advertise this temporary fixup.
5872 Based on a patch by Bruno Haible, reported and analyzed by
5873 Paul Eggert and Noah Misch.
5875 2006-04-12 Eric Blake <ebb9@byu.net>
5877 * tests/autotest.at (Debugging a failed test): Fix comment.
5879 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5881 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5882 all the changes since 2006-04-07.
5884 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5886 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5887 succeeded, but `ln -s file dir' failed, take care to remove the
5888 leftover target before the next test, to prevent its spurious
5889 failure; also make sure `ln file dir' works before selecting it.
5890 Thanks to Keith Marshall for pointing this out.
5893 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5894 assignments in `at_debug_args', so that we put them correctly
5895 in the `run' script.
5896 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5897 Reported by Eric Blake.
5899 2006-04-11 Eric Blake <ebb9@byu.net>
5901 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5902 top-level tests after micro-suite has been run. Used in...
5903 (Debugging a successful test, Debugging script and environment),
5904 (Debugging a failed test): ...these new tests. The first of these
5906 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5907 macro, split out from...
5908 (AT_INIT): ...here, so that using -d also generates a run script.
5909 Document that -d inhibits top-level logging.
5910 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5911 inhibits top-level logging; debug scripts are created.
5913 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5915 * tests/autotest.at (Empty test, Empty check): New test to check it.
5917 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5920 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5922 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5923 the files if a problem appears. Make the empty *.at files
5924 read-only, too. Proposed by Ralf Wildenhues.
5926 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5928 * config/Makefile.am: Add comment to force updated Makefile.in.
5930 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5931 space only patch to this file, this patch causes the Makefile.in
5932 files that include freeze.mk to be updated, and thus have a
5933 newer time stamp again, which in turn makes a pristine CVS
5934 checkout have correct time stamps.
5936 * Makefile.maint (cvs-sv): New macro, to be used..
5937 (config.guess-url_prefix, config.sub-url_prefix)
5938 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5939 point to CVS text checkout of Gnulib files.
5940 (copyright-check): Bump current year.
5941 (announcement): Do not hard-wire `./announce-gen'.
5942 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5944 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5946 (wget_files): Update config.guess, config.sub, texinfo.tex by
5947 `wget-update', now that their URLs work again.
5949 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5951 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5952 Problem noted by Paul D. Smith.
5954 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5956 * doc/autoconf.texi: Remove unused words from word list.
5957 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5958 .x-sc_trailing_space: New files.
5960 * doc/standards.texi: Sync from gnulib.
5962 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5963 `LIBOBJDIR' as experimental.
5965 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5966 with a target directory; it's internally implemented as `cp'
5967 anyway, but since Autoconf advertises the possibility to use
5968 a target directory when LN_S is `ln -s', we need to find out.
5969 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5970 analyzed by Keith Marshall <keith.marshall@total.com>.
5974 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5976 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5977 confdefs.h as-is. In general, if it has backslash-newline or the
5978 like, then it doesn't work either to sort or to remove empty
5981 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5983 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5985 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5987 * lib/autom4te.in (Automake-preselections): Preselect
5990 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5992 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5993 apostrophe within a single-quoted string, as this is the usual
5994 tradition and is easier to read than '"'"'. Don't rely on the
5995 shell treating "$/" like '$/'. Use a more-consistent indenting
5998 2006-04-09 Eric Blake <ebb9@byu.net>
6000 * tests/autotest.at (Backquote command substitution),
6001 (Multiline backquote command substitution): Remove mistaken
6002 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6004 (Parenthetical command substitution, Multiline parenthetical
6005 command substitution): here.
6007 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6009 Import macros from gnulib (often changing their name).

6040 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6041 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6042 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6043 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6044 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6045 (Coding Style). Don't mention m4_expand_once.

6066 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
6067 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
6069 2006-04-08 Stepan Kasal <kasal@ucw.cz>
6071 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
6072 of the warning introduced by the 2001-08-28 change.
6074 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
6075 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6077 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
6078 variables shall be overriden by the cache.

6082 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6084 Revert the patch from 2006-04-01 and only improve
6085 _AS_DETECT_BETTER_SHELL:
6087 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6088 skip nonexistent directories.
6089 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6090 only shell candidates which exist.
6091 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6092 * lib/autotest/general.m4 (AT_INIT): No need to give three
6093 parameters to _AS_PATH_WALK.
6095 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6096 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6098 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6099 distinguish m4sugar macros.
6100 * tests/tools.at (autoupdating with aclocal and m4_include):
6101 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6102 test case by Noah Misch <noah@cs.caltech.edu>.
6104 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6106 Revert my change from 2006-03-17, in other words:
6107 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6109 (AS_SHELL_SANITIZE): Remove DUALCASE=1.

6115 * doc/autoconf.texi (Programming in M4sh): Document that
6116 AS_MKDIR_P exits the script on failure.
6117 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6119 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6121 * config/elisp-comp, config/install-sh, config/mdate-sh,

6138 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6140 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6141 whether `set' quotes correctly: redirect stderr of the tested
6142 `set', and use a subshell, for Ultrix; use `sed' instead of
6143 `grep' for zsh `set' which may write binary output; match only
6144 at the beginning of a line, to avoid false positives.
6145 In order to avoid false positives by unrelated variables with
6146 multiline content, put the dump algorithm in a subshell and
6147 unset all variables containing newlines (except some which are
6148 special to the shell). Warn about cache variables that are

6153 * config/config.guess, config/config.sub, config/texinfo.tex:
6156 * tests/mktests.sh: Reword comments.

6162 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6163 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6164 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6165 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6167 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6168 shell issue with double-quoted command substitutions of native
6170 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
6173 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

6188 2006-04-06 Stepan Kasal <kasal@ucw.cz>
6190 * tests/Makefile.am (maintainer-check-posix):
6191 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6193 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6194 ac_config_<foo>s again, sometimes normalized, sometimes not.
6195 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6196 (AC_CONFIG_COMMANDS): Do not do so here.
6197 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6198 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6199 2005-07-25 rewrite. Noticed by Noah Misch.
6201 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6202 _AC_PRESERVE_HELP_ORDER, ...
6203 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6205 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
6206 inside m4_expand_once; it is redundant.
6208 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6209 for --help from Cygnus `configure.'
6211 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6222 Noah Misch <noah@cs.caltech.edu>
6224 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
6225 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
6226 * doc/autoconf.texi (Help Formatting): New node.
6227 * NEWS: Announce AC_PRESERVE_HELP_ORDER.

6232 lib/autoconf/specific.m4, lib/autoconf/status.m4,
6233 lib/autoconf/types.m4, lib/autotest/general.m4,
6234 tests/mktests.sh, tests/torture.at: White space cleanup:
6235 remove some SPACE before TAB, or add quoting ('' or @&t@).
6237 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
6239 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
6241 2006-04-05 Eric Blake <ebb9@byu.net>
6243 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
6244 empty test suite works.
6245 * tests/autotest.at (Empty test suite): Remove xfail.
6247 2006-04-05 Noah Misch <noah@cs.caltech.edu>

6264 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6265 Use 'comm' rather than N instances of grep; this also fixes a bug
6266 whereby substrings were incorrectly matched, causing us to not
6267 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6268 (exclude_list): Exclude empty macros.

6274 Switch from grep to awk syntax.
6275 (ac_exclude_script): Renamed from ac_exclude_egrep.

6352 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6353 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6354 ac_file to the name of the default output file and call
6355 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6356 initial `rm' of the candidate files...
6357 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6358 the same list in subsequent `rm' calls, and for the temporary
6359 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6360 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6361 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6362 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6363 no longer needed) by libtool. Make it a cache check.
6364 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6365 copied here by mistake.
6366 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6367 _AC_COMPILER_EXEEXT.

6440 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6442 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
6443 switch all of them on and of when necessary. Fixes the bug when
6444 m4sugar macros (e.g., m4_define) were expanded after the first
6445 automatic update (e.g., after AC_PREREQ or AC_INIT).

7174 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7175 in case the computer is too quick. Double quote the configure.ac
7178 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7179 problems if the testsuite were running too fast.
7181 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7183 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7184 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7185 (which belong to Xt, not X itself). See Debian bug 327655.
7186 * NEWS: Mention this.
7188 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7190 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7192 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7194 * config/move-if-change: Don't output "$2 is unchanged";
7195 suggested by Ben Elliston. Handle weird characters correctly.
7197 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7199 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7200 calls, so that the final expansion of this macro is shorter.
7201 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7202 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7203 the cleanup there. Use AS_VAR_* macros, to be more general.
7204 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7206 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7208 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7210 2005-09-01 Stepan Kasal <kasal@ucw.cz>

7221 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7223 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7224 The previous patch didn't work, so try a better one.
7226 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7228 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7229 in the example. Reported by Bruno Haible.
7230 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7231 "if $undefined_var;" succeeds with my shell.
7233 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7234 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7235 but change the m4_divert_text to m4_divert_once.
7237 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7239 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7240 Work around bug in Solaris /usr/xpg4/bin/awk.
7241 The bug is present in at least Solaris 8 through 10.
7243 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7245 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7246 some evil values and relying on the fact that $* concatenates the
7247 parameters by the first character from IFS.
7249 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7250 Stepan Kasal <kasal@ucw.cz>
7252 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7253 first header appears, define AH_HEADER.
7254 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7255 Update limitations about when to call AC_CONFIG_HEADERS.
7256 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7257 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7258 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7259 ``Configuration Actions''; fix their index entries.
7261 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7262 options correctly. Process N-M as M-N if M is smaller than N.
7263 Process ranges correctly so that N-N will run only N.
7264 Sort and uniquify the tests that will be run. If there is more
7265 than one test, reinsert the banners for the tests.
7266 * tests/autotest.at (Keywords): Unmark XFAIL.
7268 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7270 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7271 before passing the macro name to AH_TEMPLATE.
7273 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7274 now opens log after option processing; in particular, --version
7275 and --help do not touch config.log.

7287 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7288 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7291 * doc/autoconf.texi (Defining Symbols, Changed Results):
7292 Prepend to LIBS, not append, in examples.
7294 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7296 When building in place, set srcdir="."; suggested by Tim Van Holder.
7298 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7299 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7300 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7301 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7302 does not mean "no --srcdir option".
7304 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7306 * tests/autoscan.at (autoscan): New file.
7307 * tests/suite.at: Use it.

7313 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7315 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7316 add "2>&1"; gzip 1.2.4 prints help on stderr.
7318 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7320 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7321 was pushdef'ed twice while popped only once. Push it only once.
7322 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7324 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7326 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

7331 * Makefile.maint: Update from Bison.
7333 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7334 "<tab>" in comment, so that the point is understandable.
7336 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7338 Rewrite substantial part of lib/autoconf/status.m4.
7339 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7340 and CONFIG_COMMANDS are not processed in four separate loops.
7341 Instead, there is one main loop. This alows that the common code
7342 is expanded only once, thus config.status (and configure) is smaller.
7344 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7345 the AC_LIST_FILES and cousins macros are no longer used.
7347 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7348 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7349 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7350 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7351 contain the initialization, nor the for loop, nor the associated
7352 commands; all these go to ...
7353 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7354 _AC_OUTPUT_CONFIG_STATUS.
7355 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7356 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7357 (_AC_OUTPUT_FILE): The creation of the sed script ...
7358 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7359 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7360 _AC_OUTPUT_MAIN_LOOP.
7361 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7362 _AC_CONFIG_COMMANDS): Use ...
7363 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7364 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7365 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7366 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7367 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7368 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7370 (_AC_CONFIG_UNIQUE): Update.
7371 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7372 Replaced by this ...
7373 (_AC_LIST_TAGS): ... new common macro.
7374 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7375 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7376 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7377 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7378 this didn't belong to the `config commands' section.
7379 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7380 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7381 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7382 to the `config commands' section either.
7383 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7384 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7386 ... and many changes to the comments nearby.
7388 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7389 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7390 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7391 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7392 (#define header templates): The comment at the top of the generated
7393 header now includes the name(s) of the source file(s).
7395 Several unrelated small changes:
7397 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7398 parameter to AC_DIAGNOSE.
7399 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7400 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7401 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7402 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7404 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7405 in AC_OUTPUT doesn't double-quote it either.
7406 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7409 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7411 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7412 versions of Portland Group compiler produce single- and double-quoted
7413 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7414 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7416 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7418 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7419 This is a corrected version of yesterday's patch.
7421 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7423 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
7424 path, too; insert a "===" to emphasize the line.
7426 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
7427 ac_cv_build_alias to ac_build_alias.
7428 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7430 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7431 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7432 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7433 (AC_ARG_VAR): ... here.
7434 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7437 Keep a list of all precious variables and process them with one simple
7438 for loop, instead of expanding all commands, or, OTOH, complicated
7439 processing of output of "set".
7440 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
7441 variable names in new macro...
7442 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
7443 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
7444 a loop to assign all ac_env_* and ac_cv_env_* variables.
7445 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7447 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7448 its value to shell variable ac_precious_vars and call
7449 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
7450 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
7451 _AC_ARG_VAR_VALIDATE.
7453 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
7454 and the AC_SUBSTs ...

7471 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7472 They are generated by the Tru64 v5.1B shell.

7476 Fix my changes from 2005-07-01; reported by Noah Misch.
7477 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
7478 description, the macro now accepts only a single tag.

7481 Fix cases when the varsions of Autoconf and Autotest don't match.
7482 Reported by Noah Misch.
7483 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
7484 at_top_builddir, for compatibility with older autotest.
7485 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
7486 is not set, use at_top_builddir, for compatibility with older
7487 versions of autoconf.
7489 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7491 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
7492 Problem reported by Patrick Welche.
7494 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
7496 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7497 sed substitution command, so that we allow | in program prefixes
7498 and program suffixes. (& is a problem anyway; we're not fixing
7500 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
7501 configure_input, top_builddir, srcdir, etc.
7502 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7503 PATH_SEPARATOR in AUTOTEST_PATH.
7505 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
7507 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
7508 for loop over config.site files using `set', to allow
7509 directory names containing IFS characters.
7511 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
7513 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
7514 directories with weird names. Apparently some people like living
7515 on the edge. However, improve the test that "pwd" actually does
7516 report a name for the working directory.
7517 * NEWS: Remove the claim that we test for funny chars in dir names.
7519 2005-07-01 Stepan Kasal <kasal@ucw.cz>

7535 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
7536 document to output the default config_* lists to config.status.
7537 Don't recognize option --file, if the functionality is not there.
7538 Likewise for --header; moreover, recognize --he and --h as shortcuts
7539 for --help in that case.
7541 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7542 matches the order of execution. No code changed.

7564 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7565 (AC_SUBST): Call it.
7566 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7567 the directory specific variables; but don't call it for configure_input.
7569 2005-06-28 Derek Price <derek@ximbiot.com>
7571 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7574 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7576 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
7577 directory have inherent problems with special characters like spaces,
7578 due to limitations in Make syntax. Problem reported by Alexandre
7580 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
7581 Also, fix Tru64 porting problem with shell patterns,

7593 from Justace Clutter.
7594 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7595 variable into diagnostic. Make the diagnostic an error, not a warning,
7596 because we really don't support spaces and suchlike in dir names.
7597 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7598 Don't worry about backslashes in srcdir; it can't happen now.

7615 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
7617 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

7625 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
7626 b, t, r, w commands require single space, while : cannot have any.
7627 (Special Shell Variables): Fix sed code this in the example.
7628 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7629 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.

7639 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
7641 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
7642 * doc/autoconf.texi:
7643 Don't mention Solaris versions so much, if a
7644 problem is common to all extant versions of Solaris. Say "SunOS
7645 4" instead of "SunOS" for SunOS 4.
7646 (awk): Mention more of the limitations of traditional Awk.

7652 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
7653 but the implementation is entirely different and is designed
7654 to be compatible with glibc strverscmp.
7655 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
7657 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
7658 on Mac OS X 10.4 reported by Peter O'Gorman in:
7659 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
7660 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):

7672 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
7674 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.

7676 to update the man page. That way, we don't have to check in new
7677 man pages every month.
7679 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
7680 quotes and backslashes. Patch from Derek Price.

7689 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7690 -u, since it outputs chatter if the input files are the same.
7691 Problem reported by Ralf Menzel.
7693 2005-06-08 Derek Price <derek@ximbiot.com>
7695 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7696 renaming them since they are about to be redefined anyhow.
7698 2005-06-08 Derek Price <derek@ximbiot.com>
7700 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7701 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7702 Move m4_undefine to alphabetical order.
7704 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
7706 * README: Recommend GNU M4 1.4.3 or later.
7707 * doc/autoconf.texi (Introduction): Likewise.
7708 Reword to avoid some formatting glitches.
7709 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7710 Clarify explanation of HP compiler bug.
7711 Redo example output tp match current CVS snapshot.
7712 Use @example.org in email addresses when the examples
7713 might get inadvertently cut-and-pasted into user code.
7714 Remove example of autom4te usage that doesn't seem to work now.
7715 Use modern AC_INIT (except when the example is meant to be
7716 shown with Autoconf 2.13).
7717 Update ksh info for Solaris 9 and later.
7719 Modernize description of Automake versions a bit.
7720 Don't claim a future version of Autoconf is near.

7726 follows its own advice about quoting better.
7727 Reword to avoid some formatting glitches.
7728 * doc/installt.exi: Reword to avoid some formatting glitches.
7730 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7731 Tru64 ksh pattern matching bug. Reported against Libtool by
7732 Albert Chin <libtool@mlists.thewrittenword.com> and
7733 Nicolas Joly <njoly@pasteur.fr>.
7735 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7737 m4_cdr of one-member list was [[]] (one-member list containing an
7738 empty string) instead of [] (an empty list. Callers were skewed to
7739 match this misbehaviour. As a consequence of this:
7740 - m4_foreach([x], [], [foo]) expanded to `foo', while
7741 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7742 This bug has been fixed:
7744 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7745 expand to an empty string; print error msg if called without
7747 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7748 misbehaviour; handle [] and [[]] correctly.
7750 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7752 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
7753 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
7754 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
7756 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7758 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7759 swallow records with more than 99 fields.
7760 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7761 parse the long line.
7763 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7765 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7766 swallow literals longer than 399. Reported by Ralf Wildenhues.
7767 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
7768 to workaround this limitation.
7770 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
7772 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7773 to gfortran, and make these the first two compiler names
7774 checked (following the general autoconf preference for gcc).
7776 2005-06-03 Stepan Kasal <kasal@ucw.cz>
7778 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7779 (DISTCLEANFILES): Remove $(check_SCRIPTS).

7784 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7785 expression of unbounded size when processing the --list
7786 option. This runs afoul of a limit of 399 bytes per regular
7787 expression on AIX. Problem reported by Ralf Wildenhues.
7789 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

7792 * doc/autoconf.texi (Particular Headers): Reword example
7793 for multiline stdbool replacement.
7794 (Setting Output Variables): Reword text a bit. Don't
7795 give all the details about |#_!!_#|.
7796 Reword description of line replacement.
7798 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7800 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7801 now contain newlines, and substituted files must be referenced on
7802 a line alone; the sed scripts to substitute them are now very
7804 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
7805 commands can be put in a sed script portably.
7806 * doc/autoconf.texi (Setting Output Variables): Document above
7807 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
7808 use of multiline substitution.

7818 * tests/local.at: Don't attempt to check for negated character
7819 classes in shell scripts. The test was too brittle.
7821 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7823 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
7824 * doc/autoconf.texi (Limitations of Builtins): Document this
7827 2005-05-24 Stepan Kasal <kasal@ucw.cz>
7829 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
7830 common code; used in many places in the tree.
7831 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
7832 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
7834 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.

7837 messages when ac_unique_file is not found.
7838 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7839 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
7840 commands, for consistency with AC_MSG_ERROR and such.
7842 * bin/autoconf.as: Make more use of "shift 2" in option processing.

7854 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
7855 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7856 (ac_top_builddir): ... this ...
7857 (ac_top_build_prefix): ... to this; the old name is also kept, for
7858 backward compatibility.
7859 (ac_top_builddir_sub): New variable, without the trailing slash,
7861 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

7875 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7876 argument to m4_foreach. I guess it was necessary in the past,
7877 but I think it's a no-op now.

7881 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7882 ``cat <<_ACEOF'' commands to one.

7888 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7890 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for

7961 quoting rules. Problems noted by Stepan Kasal.
7962 Also, throughout this document, be more careful about white space.
7963 "blank", "white space", and "space" all have different meanings
7964 and we should be careful to say what we mean.

8015 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8016 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8017 comment and reduce m4_default([foo], []) to [foo].
8018 (m4_strip): Update the explanation.
8020 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8022 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8023 Remove core.conftest.* too; it's generated by Tru64 5.1.
8024 Problem reported by Jennis Pruett.
8025 * lib/autoconf/functions.m4
8026 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8027 Don't bother to remove core files; AC_RUN_IFELSE should do that

8032 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

8077 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8078 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8080 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>

8083 a directory whose name contains a special character like space,
8085 * doc/autoconf.texi (Installation Directory Variables): Allow

8095 unportable file names.
8096 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8098 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8099 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8100 ac_pwd, and quote srcdir.
8101 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8103 * doc/autoconf.texi: Fix some systematic formatting problems.
8104 ".)" needs a following @: if not at the end of a sentence, and
8105 similarly for "!)". "etc." should be preceded by a comma.
8106 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8108 2005-03-22 Bruno Haible <bruno@clisp.org>
8110 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8111 argument is often called 'build-aux'.
8113 2005-03-07 Stepan Kasal <kasal@ucw.cz>

8120 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8122 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8123 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8124 from a Common Lisp's `cl'.
8125 (AC_PROG_CXX): Behave according to the documentation: don't
8126 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8127 make the variable CCC precious; use `cl.exe', not `cl'.
8129 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8130 Alexandre Duret-Lutz <adl@gnu.org>
8132 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8133 /dev/null, as "configure" shouldn't read stdin, and this insulates
8134 us from problems (e.g., when testing for "cl"). Also, do this
8135 redirection before invoking "hostname" or "uname", and keep the
8136 original input stream available via...
8137 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8138 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8139 bother with "</dev/null" since it's now done at the top of

8150 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8151 newline if neither \c nor -n work, as that would output two
8152 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8154 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8156 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8157 This causes that any required macros inside will get before the if.
8158 * doc/autoconf.texi (autom4te.cache): A typo.
8160 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8162 Undo previous change, except keep the change to
8163 lib/autoconf/programs.m4 that replaced grep with shell
8164 pattern-matching. This is because net-snmp configure reads stdin.
8165 Reported by Noah Misch.
8167 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8169 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8170 from /dev/null, as "configure" shouldn't read stdin, and this
8171 insulates us from problems (e.g., when testing for "cl").
8172 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8173 before invoking "hostname" or "uname".
8174 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8175 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8176 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8177 "</dev/null" since it's now done at the top of 'configure'.
8178 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8179 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8180 Also, replace grep with shell pattern-matching, to save a process.
8182 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8184 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8185 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8186 avoid thinking that Allegro Common Lisp's "cl" command is a C++

8191 * doc/autoconf.texi (Limitations of Usual Tools): Document that

8200 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8202 * doc/autoconf.texi: Use @acronym for DJGPP.
8203 Fix some @code's that should have been @env's, and vice versa.
8204 Sort environment variable names.
8205 Mention that shells no longer inherit IFS.
8206 Don't recommend PATH_SEPARATOR=';' so strongly.
8207 Mention that $RANDOM might expand to the empty string.
8208 "symlink" and "soft link" -> "symbolic link".
8209 Improve mktemp description (reported by Bruno Haible).

8285 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8287 Try not to generated lines of unlimited length, as POSIX places a
8288 2047-byte limit on line length of portable text files.
8289 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8290 Use newline as a separator, not space.

8348 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8349 Update the long comment explaining it.
8351 m4_require no longer writes an ``is required by'' line to the
8352 execution stack. It contains only one bit of non-redundant
8353 information: that the macro was required, not called. And even
8354 this bit is useless in most situations: have you ever met a macro
8355 which both calls and requires the same macro?
8357 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8358 (_m4_defun_pro_outer): ... only via this macro, for the outermost

8361 (m4_expansion_stack_pop): Remove the misplaced comment.

8363 execution stack; slightly improve the out-of-a-defun error message.
8364 (_m4_divert_grow): New macro, counter for the temporary diversions.
8365 (_m4_require_call): Use it.
8366 * tests/m4sugar.at (m4_require): Expect output without the
8367 ``is required by'' messages.
8369 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8371 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X

8405 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
8406 Warn about newline stripping in `` and $(). Update Solaris
8408 (Limitations of Builtins): Use expr "X...", not expr "x...", as
8409 X insulates us from future changes to Posix.
8410 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
8413 2005-01-19 Stepan Kasal <kasal@ucw.cz>
8415 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

8435 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
8437 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

8458 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
8459 (_m4_divert_n_stack): New macro; the expansion is
8460 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
8462 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
8463 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8464 stored in _m4_divert_diversion or _m4_divert_dump.
8465 (m4_divert_pop): When the parameter is given, compare the symbolic
8466 name with the last diversion pushed on the stack. Previously, the
8467 current diversion was compared with the numeric value of the
8468 diversion given as the parameter.
8469 (m4_require): If the macro hasn't been expanded yet, call ...
8470 (_m4_require_call): this new macro.

8503 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
8504 signals that the package uses Automake; a `Makefile.am' is typical but
8505 not essential. Reported by Magnus Therning.

9013 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
9015 * doc/autoconf.texi (Shellology): Mention BIN_SH.
9016 Document problem with "`""`" in pdksh POSIX mode.
9018 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9020 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9021 with pdksh, too. Problem reported by Patrick Welche via
9023 * doc/autoconf.texi (Shellology): Note that set -o posix is
9024 useful for pkdsh, too.
9026 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9028 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9029 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9030 Don't fail if ENV or BASH_ENV is readonly.
9031 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9032 etc. are read only. Problem reported by Ludovic Courtes.
9034 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9036 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9037 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9040 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9042 * doc/autoconf.texi (File System Conventions): Warn about
9043 names like "aux". Problem reported by Eric Blake.
9045 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9046 by zero instead of array size, so that we can use any arithmetic
9047 constant expression (instead of requiring an integer constant
9048 expression). This allows us to test expressions like DBL_MAX <
9049 LDBL_MAX, which didn't conform to the C standard using the old
9051 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9052 now that we can do floating-point tests at compile time.
9054 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9056 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9057 and LDBL_EPSILON, as the resulting expression isn't an
9058 integer constant expression and violates the C standard.
9059 Problem reported by Nelson H. F. Beebe. Also, check
9060 for "L" suffix, and check that long double doesn't have
9061 worse range or precision than double, that mixed-mode
9062 arithmetic doesn't generate a diagnostic, that double
9063 constants fit in long double.
9065 2004-06-03 Kevin Ryde <user42@zip.com.au>
9067 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9068 malloc(0) and realloc(NULL,size).
9070 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9073 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9075 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9076 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9079 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9081 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9082 can be rewritten using if-then-else. Suggested by Bruno Haible.
9084 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9086 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9087 Problem reported by Stepan Kasal.
9089 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9091 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9092 change). Patch reported by Ralf Wildenhues in
9093 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9095 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9096 function F exists if the compiler and linker let you compile an
9097 expression like (F != 0). Recent versions of GCC optimize away
9098 the reference to F in that case, since every function address must
9099 be nonzero, so the link succeeds even if F does not exist.
9100 Problem reported by Manu in
9101 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9103 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9104 "Unix". Many uses changed.
9105 (Limitations of Builtins): Explain better why the ! command isn't
9108 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9110 * lib/autom4te.in (Automake-preselections): Preselect
9111 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9113 2004-05-19 Kevin Ryde <user42@zip.com.au>
9115 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9116 referencing AC_FUNC_STRERROR_R.
9118 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9119 note pessimistic assumption when cross compiling.
9121 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9123 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9124 (until 2004) invoked subcommands with sh -e, contra POSIX.
9125 Reported by Kevin Ryde.
9127 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9129 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9130 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9131 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9132 `test -f " /usr/bin/grep"', which _always_ failed.
9133 (AC_PROG_SED): Ditto bogus PATH fix.
9134 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9135 requires that grep correctly supports _multiple_ `-e' options, rather
9136 than stating only that grep should accept `-e'.
9138 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9140 Port to C99, which requires that 'exit' be declared.
9142 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9143 to ensure that stdlib.h is included.
9144 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9145 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9146 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9147 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9148 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9149 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9150 when using 'exit' in a test; C99 requires that 'exit' be declared.
9152 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9154 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9155 now prefers 'grep' implementations that accept -e.
9156 (Limitations of Usual Tools): Describe problems of traditional
9157 egrep and fgrep with long input lines, and of traditional grep
9159 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9160 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9161 All callers changed. Append /usr/xpg4/bin to the PATH, for
9163 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9164 the user with complaints about multiple -e options.
9165 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9166 Define it with AC_PROG_GREP.
9167 * configure.ac (AC_PROG_GREP): Add.
9168 * lib/freeze.mk (GREP): New macro.
9170 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9172 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9173 a possible candidate only after all others fail, rather than
9174 consulting it first. This improves backward compatibility by
9175 better reflecting the way shell selection occurred in previous
9176 versions of Autoconf, and should help to avoid triggering latent
9177 problems in other packages, such as the one in Automake where zsh
9178 is not handled robustly:
9179 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9180 Although it is not Autoconf's responsibility to work around
9181 problems in Automake, it nevertheless makes sense to avoid
9182 introducing unnecessary incompatibilites.
9184 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9185 Gary V. Vaughan <gary@gnu.org>
9187 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9188 how deeply nested we are when a suitable tool is found, set the
9189 ac_path_TOOL_found flag.
9190 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9191 nested we are in this macro. Break out of all 3 nested loops if
9192 ac_path_TOOL_found is set.
9194 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9196 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9197 of the _AS_PATH_WALK loop too if GNU flavor is found.
9199 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9201 * doc/autoconf.texi (Limitations of Make): Update documentation
9202 for `$<'. New entry `Long lines', based on a report from Simon
9203 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9204 paragraph about DJGPP, based on a mail from Richard Dawe.
9206 2004-04-20 Paul Eggert <eggert@twinsun.com>
9208 * tests/c.at (C keywords): Don't assume that GCC supports
9209 "restrict" and "inline", as sufficiently-old GCC versions do not
9210 (also, GCC configured to be in pedantic C89 mode does not).
9211 Problem reported by Sumit Pandya in:
9212 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9214 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9215 consider -g to work if it generates warnings when plain compiles
9216 don't. Problem reported by Braden McDaniel in:
9217 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9219 * doc/autoconf.texi (Slashes): New section, to document a problem
9220 reported by Jim Meyering in:
9221 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9223 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9224 linker output files before linking, to work around IRIX 6 linker bug.
9225 Problem reported by Rainer Orth in:
9226 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9228 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9230 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9231 best tool so far counter rely on the tool path variable name to
9232 avoid checks for one tool being affected by the results of running
9233 the length check on a previous tool.
9235 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9236 match expression argument, as different greps have different
9237 regular expression flavours.
9238 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9240 (AC_PROG_EGREP): Pass 'EGREP$'.
9241 (AC_PROG_GREP): Pass 'GREP$'.
9243 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9245 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9246 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9248 2004-03-29 Paul Eggert <eggert@twinsun.com>
9250 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9251 Types, Specific Compiler Characteristics, System Services,
9252 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9253 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9254 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9255 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9257 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

9270 HAVE_STRUCT_TM_TM_ZONE is not defined.
9271 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9272 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

9283 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9284 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9285 H. F. Beebe for the bug report.

9339 2004-03-03 Paul Eggert <eggert@twinsun.com>
9341 * bin/Makefile.am (edit): Don't use $< in a context where
9342 POSIX doesn't require support for it. Use $@.in instead.
9343 Problem reported by Anthony N. Frasso in
9344 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

9376 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9377 Darwin uses -lcrt2.o and there's little point to cataloging all
9378 the system variants. Partial fix reported by Andreas Waechter in:

9469 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
9470 _AC_PROG_GREP, and AC_PROG_SED.
9471 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
9472 longest input length accepted by a command.
9473 (AC_PROG_SED): Use it.
9474 * doc/autoconf.texi (Particular Programs): Document the changes.
9477 2004-01-27 Paul Eggert <eggert@twinsun.com>
9479 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
9480 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
9481 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
9482 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
9484 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
9485 bin/autoconf.in, config/Makefile.in, config/config.guess,
9486 config/config.sub, config/install-sh, config/mdate-sh,

9501 2004-01-26 Paul Eggert <eggert@twinsun.com>
9503 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9504 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9505 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9506 not <inttypes.h>. Problem reported by Tim Mooney in
9507 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9508 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9511 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9512 otherwise "make check" fails because it forbids cmp (I guess
9513 because cmp treats files as binary on DOS-like systems).
9515 * tests/mktests.sh: Update copyright date to 2004, since some tests
9516 have changed in 2004.
9518 2004-01-23 Gary V. Vaughan <gary@gnu.org>
9520 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
9521 non-truncating sed or gsed program in PATH.
9522 * tests/acprograms.at: Add it.
9523 * doc/autoconf.texi (Particular Programs): Document it.
9526 2004-01-15 Paul Eggert <eggert@twinsun.com>
9528 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9529 -std1 disables some useful extensions on Tru64. Problem reported
9531 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
9533 2004-01-14 Paul Eggert <eggert@twinsun.com>
9535 * doc/autoconf.texi (Programming in M4sh): Document that
9536 AS_MKDIR_P succeeds if the destination is a symbolic link
9537 to an existing directory.
9538 (Limitations of Usual Tools): Note that mkdir -p might not
9539 succeed on symlinks to directories.
9541 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9543 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
9544 * bin/autoheader.in: Grammar fix in message.
9545 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):

9548 2004-01-13 Eric Blake <ebb9@byu.net>
9550 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
9551 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
9553 2004-01-10 Jim Meyering <jim@meyering.net>
9555 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
9557 2004-01-09 Paul Eggert <eggert@twinsun.com>
9559 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9560 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9561 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9562 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9563 AC_COMPILE_IFELSE, since we now assume our caller invokes
9564 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9565 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9566 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9567 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9569 2004-01-07 Paul Eggert <eggert@twinsun.com>
9571 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9572 `"'...'"`, as it's confusing (and I suspect it may not work on
9573 some platforms). The code was incorrect anyway, as it assumed
9574 that \$ evaluated to itself in that context. Reported by
9575 Alexandre Duret-Lutz.
9577 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9579 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
9580 and _LT_AC_TAGCONFIG.
9582 2004-01-06 Paul Eggert <eggert@twinsun.com>
9584 * doc/autoconf.texi (One Macro Call): Fix an incorrect
9585 example, and add more examples. Reported by Eric Sunshine.
9587 2004-01-05 Paul Eggert <eggert@twinsun.com>
9589 * doc/autoconf.texi (Limitations of Usual Tools):
9590 Remove warning against "rm -fr" introduced yesterday; it
9593 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
9594 autoscan, autoupdate, ifnames): Don't use chmod -w.

9603 by doing lineno substitution only on lines containing "$LINENO".
9605 2004-01-04 Paul Eggert <eggert@twinsun.com>
9607 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
9608 Use "rm -f" to remove conftest.sed, not plain "rm".
9609 Bug reported by David Relson in
9610 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9612 * Makefile.am (autom4te-update):
9613 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
9614 * Makefile.maint (my-distcheck, do-po-update): Likewise.
9615 * doc/autoconf.texi (Guidelines): Likewise.

9622 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
9624 * doc/autoconf.texi (Limitations of Usual Tools):
9625 Warn against "rm -fr".
9627 2004-01-03 Paul Eggert <eggert@twinsun.com>
9629 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9630 -c -o might not work. From a suggestion by Kevin Ryde.
9631 (C Compiler, Generating Sources, Limitations
9632 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9633 Don't put '-o' after non-options, as POSIX doesn't allow this.
9634 Mention that cc's name might be gcc or c89 or whatever.
9636 2004-01-04 Kevin Ryde <user42@zip.com.au>
9638 * doc/autoconf.texi: Add various further index entries.
9640 2003-12-29 Paul Eggert <eggert@twinsun.com>
9642 * bin/autoreconf.in (autoreconf_current_directory):
9643 Fix typo: mkdir without umask arg.
9645 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9647 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9648 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
9649 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
9650 explanation clearer.
9652 2003-12-24 Andreas Schwab <schwab@suse.de>

9660 * configure: Regenerate.
9661 * tests/atlocal.in: Store the result here.
9662 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
9663 tools.at, looking in atlocal's ac_cv_sh_n_works instead
9664 of explicitly testing.
9665 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
9666 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
9667 * tests/tools.at (Syntax of the shell scripts): Simplify

9685 (AS_SHELL_SANITIZE): Move reinvocation code from
9686 _AS_LINENO_WORKS, use it to find out if shell
9688 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
9690 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
9691 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
9693 * lib/autotest/general.m4: Use AS_INIT_WITH_SHELL_FN.

9742 the expanded body, consistently with other macros such as AC_USG.
9744 2003-11-17 Paul Eggert <eggert@twinsun.com>
9746 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes

9778 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

9958 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
9960 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
9961 cache variable instead of $G77 to decide whether to include -O2,
9962 since $G77 is specific to Fortran 77.
9964 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9966 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
9967 free" flag. Re-order flags tested into rough order of popularity.
9969 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9971 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
9972 arguments so that it can be used with syntax identical to
9973 AC_PROG_F77, and so that we can more easily decide to
9974 remove/deprecate the DIALECT optional argument in the future if it
9976 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
9977 non-freeform-supporting compilers. Document freeform flags.
9979 2003-10-03 Akim Demaille <akim@epita.fr>

9984 2003-10-03 Akim Demaille <akim@epita.fr>
9986 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
9987 * bin/autoreconf.in (autoreconf_current_directory): Create the
9988 AUX_DIR if needed, for sake of automake --add-missing etc.
9989 Suggested by Alexandre Duret-Lutz.
9991 2003-10-03 Akim Demaille <akim@epita.fr>
9993 * configure.ac: Quotation and formatting changes.

10040 Problem reported by Lars J. Aas in
10041 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10042 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10043 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10044 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10046 2003-09-26 Akim Demaille <akim@epita.fr>
10048 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10049 directory for AC_CONFIG_COMMANDS' first argument exists.
10050 This makes valid the invocation of _AC_SRCPATH that follows.
10051 Reported by Eric Sunshine.
10052 * doc/autoconf.texi (Configuration Commands): Adjust.
10054 2003-09-26 Akim Demaille <akim@epita.fr>

10069 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
10070 Problem reported by Eric Sunshine in:

10075 The test suite are sometimes assigning timings incorrectly.
10076 Reported by Henk Krus.
10077 Diagnosed by Nicolas Joly.
10079 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10081 Instead of making AT_help a sequence of assignments to grow
10082 $at_help_all, just make AT_help_all be the growing contents of
10083 $at_help_all, and make a single assignment in...
10085 (at_times_skip): Flip the meaning and rename as...
10086 (at_times_p): this.
10087 (AT_INIT): When summarizing the test that ran, remove
10088 $at_times_file after use, and check it is present before trying to

10095 * bin/Makefile.am (edit): Handle '@configure_input@'.
10096 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
10097 (ifnames): chmod -w.
10098 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10099 executables, not bin/ executables! Otherwise all the magic needed
10100 to find non installed files is turned off. This caused a failure
10101 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10102 as found in its environment (sent by tests/autoreconf): pointing
10103 to bin/autom4te that could not find its files.
10104 * tests/mktests.sh: Force the replacement of generated files, for
10105 the sake of "mv" program that are interactive when overwriting a

10114 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10115 Paul Eggert <eggert@twinsun.com>
10117 Trivial change to support GCC's configuration procedure.

10200 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10202 Add support for newer Fortran dialects. The F77 interface is
10203 unchanged, and continues to support Fortran 77. New FC macros
10204 correspond to all the old F77 macros, with output variables FC,
10205 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10206 available dialect, but older dialects can be specified. There are
10207 new macros AC_FC_SRCEXT to set the source extension, and
10208 AC_FC_FREEFORM to accept free-form source files.
10210 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

10331 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10332 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10334 2003-08-21 Akim Demaille <akim@epita.fr>
10336 First stab at preserving warnings between calls to autom4te,
10337 including when the cache is used.
10339 There are still several issues: (i) there are too many runs of m4
10340 (one for include, one for warnings, and some more), (ii) warnings
10341 spreading on several lines are not handled gracefully, (iii) the
10342 code meant to have the call stack display for errors does not work
10343 (its handling should move from m4 to autom4te).
10345 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10347 (@preselect): Add m4_warn.
10348 ($exit_status): Remove, use $exit_code.
10349 ($help): Use Autom4te::ChannelDefs::usage.
10350 (&handle_m4): No longer define the m4_warnings.
10351 At each run, extract and report the warnings.
10352 Always cache the result, including if the exit status is on
10353 failure, since if nothing changes, we should result in the same
10354 failure, hence we can use the cache.
10355 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10356 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10358 (m4_warn): Redefine as a do-nothing: it is its invocation that
10359 matters, as warnings are now reported via traces.
10360 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10361 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10362 the latter reveals calls to the former.
10366 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

10399 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10400 * bin/autom4te: Adjust.
10401 In particular, be Autoconf tools are really silent when properly
10402 working, bind the verbosity of the 'note' channel to $verbose.
10403 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)

10476 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
10477 (AT_CHECK_NOESCAPE): Move core functionality to...
10478 (_AT_CHECK): ...this new macro.
10480 2003-08-07 Derek Price <derek@ximbiot.com>
10482 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
10483 (AT_CHECK_NOESCAPE): ...to this new macro.
10485 2003-07-31 Paul Eggert <eggert@twinsun.com>
10487 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
10488 in Bash 2.01. Problem reported by Brian Gough in
10489 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
10491 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
10493 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
10494 -lcrt1.o, for OS X. (trivial change)
10496 2003-07-07 Paul Eggert <eggert@twinsun.com>
10498 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
10499 inside '#ifndef __cplusplus'. Problem reported by
10502 2003-07-06 Bill Clarke <llib@computer.org>
10504 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10505 'long', not 'int', for benefit of Sun's recent C++ compilers
10506 (trivial change). See:
10507 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

10513 * lib/Makefile.am (autom4te.cfg): Make it read only.
10514 Depend on Makefile since it contains substitutions.
10515 From Paolo Bonzini.

10523 From Gareth McCaughan.
10525 2003-06-23 Akim Demaille <akim@epita.fr>
10527 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10528 not all of them. This fixes 1. the fact that when testing
10529 Autoconf there are many many config.log, 2. the incorrect use of
10530 top_srcdir to find config.log.
10531 Don't mix the detailed output of failed test with the summary of
10532 failures. Rather, append detailed log afterwards.
10534 2003-06-23 Akim Demaille <akim@epita.fr>
10536 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
10537 always run: output config.log on $at_group_log.
10539 2003-06-23 Akim Demaille <akim@epita.fr>
10541 * tests/torture.at (#define header templates): Don't use quotes in
10542 C++ comments as it puzzles Emacs' sh font-lock-mode.
10544 2003-06-23 Akim Demaille <akim@epita.fr>
10546 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
10547 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
10548 * tests/atspecific.m4: Rename as...

10557 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
10558 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
10559 ensuring we add -std1 for full-ANSI.
10561 * doc/autoconf.texi (hdrindex): New macro.
10562 Add index entries for portability of various standard header files.
10564 2003-06-20 Akim Demaille <akim@epita.fr>

10572 2003-06-20 Akim Demaille <akim@epita.fr>

10591 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.

10594 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
10595 (AT_INIT): Support for expected failures.
10597 2003-06-02 Akim Demaille <akim@epita.fr>
10599 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space

10602 Autoconf nor Automake.
10603 (&contents): New, from Automake.
10606 2003-05-28 Paul Eggert <eggert@twinsun.com>
10608 * NEWS, doc/autoconf.texi (Particular Functions),

10610 is the inverse of localtime.
10612 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
10614 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10615 (handle_exec_errors): New function. Work around $! being
10616 altered by WEXITSTATUS.
10617 (xqx, xsystem): Use handle_exec_errors.
10619 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10621 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10622 Do not call `_exit()', simply modify `$?'.
10623 (xsystem): Reset $! before running system, and check it afterward.
10624 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10625 63 for version mismatches.
10627 2003-05-23 Akim Demaille <akim@epita.fr>
10629 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10630 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10631 the middle of a line).
10632 * lib/m4sugar/m4sugar.m4: Likewise.
10633 Remove useless spaces in comments.
10635 2003-05-23 Akim Demaille <akim@epita.fr>
10637 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10638 exit 63, so that we (or Automake's "missing") can tell the
10639 difference with a plain failure.
10640 * doc/autoconf.texi (Notices): Adjust.
10642 2003-05-23 Akim Demaille <akim@epita.fr>
10644 * Makefile.am, bin/Makefile.am, config/Makefile.am,
10645 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
10646 White spaces cleanup.
10648 2003-05-22 Jim Meyering <jim@meyering.net>
10649 Paul Eggert <eggert@twinsun.com>
10651 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10652 Remove `#include <stdlib.h>' from the list; we should never
10653 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10654 resulting namespace pollution would cause other tests to fail.
10655 Configure scripts run with some older versions of g++ and HP's
10656 aCC would fail due to such an #include. Problems reported by
10657 Matthew Mueller in <http://bugs.debian.org/120704> and by
10659 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10660 In the test, use the test declaration before including <stdlib.h>,
10661 as that's closer to how it'll be used.
10663 2003-05-23 Akim Demaille <akim@epita.fr>
10665 * doc/autoconf.texi (Header Portability): ucred.h.
10668 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10670 Overhaul Autotest's logging: generate separate log files
10671 in testsuite.dir/NNN/testsuite.log, and append them to
10672 testsuite.log instead of re-running the test verbosely.
10674 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10675 file descriptor, write 0 to at_status_file instead of setting
10676 at_status=0, initialize some new variables (at_status_file,
10677 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10678 to rerun the tests, instead append the at_group_log to the
10679 at_suite_log when a test fails.
10680 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10681 with the AS_MESSAGE_LOG_FD redirected to stdout.
10682 (AT_CLEANUP): save the output status in $at_status_file
10683 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10684 its original place.
10685 (AT_CHECK): since tests are run with a redirected stdout,
10686 and used to be re-run in verbose mode, turn some $at_verbose
10687 into echo, and don't redirect the output of testing stdout
10690 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10691 the name of the debugging directory and information about

10811 2003-05-06 Akim Demaille <akim@epita.fr>
10813 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10814 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10815 by aclocal.m4 is changed it might require the importing of another
10816 m4 extension file, i.e., aclocal must be run.
10818 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10819 (&parse_args): Use --force with aclocal if required and supported.

10833 2003-04-29 Derek Price <derek@ximbiot.com>
10835 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10836 seperator with m4_append_uniq(). It doesn't work.
10837 (AT_CLEANUP): Add `;' to end of at_help_all.
10838 (AT_INIT): Allow --keywords to be specified more than once. When
10839 grepping $at_help_all for keywords, use the field and keyword
10840 seperators to ensure a complete keyword match. Alter at_prev handling
10841 to support the new --keywords behavior.
10843 2003-04-27 Karl Berry <karl@freefriends.org>
10845 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10846 align better with others. I also made some of the individual
10847 entries on one line, for brevity and to make it easier for me to
10848 sort my dir-example file in the Texinfo distribution :).

10914 reading the section "Present But Cannot Be Compiled" when the
10915 header causes problems.
10917 2003-03-28 Akim Demaille <akim@epita.fr>
10919 * tests/torture.at (Configuring subdirectories): Require aclocal
10920 1.4, otherwise the test fails, as it does support configure.ac.

10943 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
10944 obsolete AC_HELP_STRING.

11011 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
11012 to cope with DOS-style absolute paths, when constructing
11015 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
11016 When constructing paths with IFS=:, quote the path. If we're
11017 constructing a DOS-style absolute path, we don't want to split it

11040 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
11041 format starting with "-".
11043 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
11045 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
11046 is not portable inside Makefile.
11048 2003-02-20 Akim Demaille <akim@epita.fr>
11050 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
11051 compiler says yeah, but preproc says nope, compiler is right.

11063 $ac_prefix_program.
11066 2002-12-23 Paul Eggert <eggert@twinsun.com>
11068 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11069 innocuous variant befor including <limits.h> or <assert.h>. This
11070 works around a bug reported by Albert Chin: HP-UX 11i
11071 (and earlier versions) have a <limits.h> that declares
11072 gettimeofday and many other functions.
11074 2002-12-03 Paul Eggert <eggert@twinsun.com>
11078 * NEWS, configure.ac: Update version.
11080 * doc/fdl.texi: Upgrade to FDL version 1.2.
11082 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11083 nontrivially in main's body, so that f's external declaration is
11084 not optimized away in AIX. This should fix the bug reported by
11086 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11088 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11089 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11090 defined, to support freestanding compilers. This should fix the
11091 bug reported by Momchil Velkov in
11092 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11094 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11095 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

11126 Update from masters.
11128 2002-11-14 Akim Demaille <akim@epita.fr>
11130 * Makefile.maint: Sync with Bison, i.e.:
11131 (po-check): Scan .l and .y files instead of the
11132 .c and the .h files that they generate. This fixes the bug
11133 reported by Tim Van Holder in:
11134 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11135 Look for N_ as well as for _. Try to avoid matching #define for
11139 2002-11-14 Akim Demaille <akim@epita.fr>
11141 * doc/autoconf.texi (C Compiler): Compiling several files at once.
11142 From Paul Eggert and Albert Chin-A-Young.
11144 2002-11-14 Akim Demaille <akim@epita.fr>
11146 * doc/autoconf.texi (C Compiler): Solitary backslashes.
11147 From Paul Eggert and Albert Chin-A-Young.

11151 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11152 than assigning in main, to avoid HP cc +O3 optimizing it away.
11154 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11156 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11157 option. Process --recheck after parsing all options. Pass -q
11158 option to configure on --recheck.
11159 (AC_OUTPUT): Pass -q from configure to config.status.
11160 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11161 arguments to record.
11162 * doc/autoconf.texi (config.status Invocation): Document
11163 config.status -q option.
11165 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11167 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11168 Makefile.in if Makefile.am exists.
11169 (output): Strip `.am' from Makefiles. Don't
11170 output AC_CONFIG_FILES if no Makefiles were found.

11190 Reported by Ezra Peisach.
11192 2002-11-05 Akim Demaille <akim@epita.fr>
11194 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11196 We _have_ to stop using the old compatibility scheme that tried to
11197 avoid useless backslashes because Libtool 1.4.3 contains a
11198 AC_DEFINE([error_t], [int],
11199 [Define to a type to use for \`error_t' if it is not
11200 otherwise available.])
11201 We _have_ to quote the single quote and backslashes with \. The
11202 old compatibility scheme saw that ` was backslashed, and therefore
11203 did not quote the single quote. Hence before this patch, Autoconf
11204 was not compatible with Libtool.
11206 2002-11-04 Paul Eggert <eggert@twinsun.com>
11208 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

11226 ($help, $make, &parse_args, &autoreconf_current_directory):
11228 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11230 2002-10-31 Bruno Haible <bruno@clisp.org>

11248 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
11249 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
11250 Make variable, not a shell variable.
11251 Suggested by Bruno Haible.
11253 2002-10-31 Akim Demaille <akim@epita.fr>
11255 * bin/autom4te.in (load_configuration): Reject #args out of any
11258 2002-10-31 Akim Demaille <akim@epita.fr>
11260 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
11261 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)

11274 2002-10-29 Paul Eggert <eggert@twinsun.com>

11277 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
11278 Problem reported by Bruno Haible.
11280 2002-10-29 Akim Demaille <akim@epita.fr>
11282 * doc/autoconf.texi (Header Templates): Put also in words what the
11283 pictures says to assist free style readers.
11284 (Customizing autom4te): s/--cache=/--cache /.
11286 2002-10-29 Akim Demaille <akim@epita.fr>
11288 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
11290 sparc_address_test returns void.
11291 Use it with an argument, as prototyped.
11294 2002-10-29 Akim Demaille <akim@epita.fr>

11595 Reported by Alexandre Duret-Lutz.
11597 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

11658 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11659 aclocal invocation, as Gettext macros might not be visible to
11661 Instead of blindly running autopoint, scan configure.ac (not the
11662 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11663 Reported by Paul D. Smith.
11665 2002-10-08 Paul Eggert <eggert@twinsun.com>

11695 * tests/torture.at (Configuring subdirectories): Be robust to

11921 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
11922 looking for a replacement file.
11923 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11924 directory is relative.
11925 * doc/autoconf.texi (Generic Functions): Clarify the replacement
11926 directory definition.
11927 Reported by Andreas Schwab and Jim Meyering.

11931 * doc/autoconf.texi (Setting Output Variables): Clarify what
11932 precious variables are.
11933 Suggested by Pontus Skoeld.
11935 2002-09-05 Akim Demaille <akim@epita.fr>
11937 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11938 (ifnames, autoscan, autom4te): Since we don't only depend on
11939 configure.ac variables (such as VERSION etc.), but also on prefix
11940 and so forth, depend on Makefile, not configure.ac.
11941 Reported by Alexandre Duret-Lutz.
11942 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11944 2002-09-05 Kevin Ryde <user42@zip.com.au>
11946 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11947 doesn't seem to be confined to ia64, just say "some versions".
11949 2002-09-04 Akim Demaille <akim@epita.fr>
11951 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11953 * Makefile.am (maintainer-clean-local): Remove.
11954 (MAINTAINERCLEANFILES): Remove COPYING.
11956 2002-09-03 Paul Eggert <eggert@twinsun.com>
11958 * doc/autoconf.texi (Configuration Commands): Remove obsolete
11959 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
11962 2002-09-03 Akim Demaille <akim@epita.fr>
11964 * configure.ac: Bump to 2.53d.
11965 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11966 as of today, on Automake's team suggestion.
11968 2002-09-03 Akim Demaille <akim@epita.fr>
11972 2002-09-02 Akim Demaille <akim@epita.fr>
11974 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
11976 * configure.ac: Disable SITE_MACRO_DIR.
11978 2002-09-02 Jim Meyering <meyering@lucent.com>
11980 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11981 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11982 Also, tweak grammar: s/make sure to/be sure to/.
11984 2002-09-02 Paul Eggert <eggert@twinsun.com>
11986 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11987 directory names are generally preferable to physical names.
11989 2002-09-02 Akim Demaille <akim@epita.fr>
11991 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11992 Reported by Raja R. Harinath.
11993 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11994 * bin/autoupdate.in: Use error instead of die.
11996 2002-09-01 Paul Eggert <eggert@twinsun.com>
11998 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11999 ordinary shell concatenation rather than echo+tr+sed command that
12000 runs afoul of a long-line-related sed bug in Solaris 8.
12002 * bin/autoheader.in (parse_args): --warning -> --warnings.
12004 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12005 stdout, as traditional "ls" does.
12006 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12007 _AC_COMPILER_EXEEXT_O): Likewise.
12008 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12010 * bin/autoconf.as: Add --prepend-include option. This patch was
12011 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12012 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12014 * bin/autoconf.in, configure: Regenerate.
12016 * doc/autoconf.texi (Special Shell Variables): Mention
12017 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12019 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12020 MAILPATH and set PS1, PS2, PS4 to default values, to work
12021 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12022 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12023 the Autoconf documentation specifies; fall back to "unset" only if
12024 this fails. Use a shell for-loop for this rather than an m4 loop,
12025 to shorten the output script.
12027 2002-08-30 Paul Eggert <eggert@twinsun.com>
12029 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12030 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12031 for the CDPATH problem. Document PWD.
12032 (Limitations of Builtins): Document the problem that "cd $foo" and
12033 "ls $foo" may refer to different directories in shells conforming
12034 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12035 example, since the old example is now out of date.
12037 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12038 FOO" and "ls FOO" talk about different directories; this catches
12039 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12042 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12043 of rolling our own unset.
12044 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12045 in practice we needn't worry about CDPATH if unset doesn't work.
12047 * Makefile.in, aclocal.m4, bin/Makefile.in,
12048 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12049 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12050 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12051 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12052 tests/Makefile.in: Regenerate with Automake 1.6.3.
12054 * config/config.guess, config/config.sub, config/mkinstalldirs:
12057 * configure: Regenerate with self.
12059 2002-08-30 Kevin Ryde <user42@zip.com.au>

12069 2002-08-29 Akim Demaille <akim@epita.fr>
12071 * lib/Autom4te/General.pm (&xqx): New.
12072 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12073 hand, which is not portable.
12075 * bin/autom4te.in: Use them.
12076 Use &error instead of die.
12077 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12080 2002-08-17 Paul Eggert <eggert@twinsun.com>
12082 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12083 default list of compilers to try, since it was long ago superseded
12084 by the ksh fc builtin. Suggested by Steven G. Johnson.
12086 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12088 * doc/autoconf.texi (Invoking autom4te): End the option table,
12089 fixing a bug introduced by the previous patch.
12090 (Limitations of Make): Add a 'target lookup' subentry in the
12091 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12093 2002-07-29 Mark D. Roth <roth@feep.net>
12095 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12096 options and use $AUTOM4TE_PATH.
12097 * doc/autoconf.texi: Remove documentation of autom4te
12098 --include-envvar and --site-macro-subdir options and document
12099 use of $AUTOM4TE_PATH.
12100 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12101 arguments from each language section.
12103 2002-07-29 Paul Eggert <eggert@twinsun.com>
12105 * doc/install.texi: Include copyright symbol in copyright notice.
12107 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12109 (AM_MAKEINFOFLAGS): New macro.
12110 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12111 * Makefile.am (INSTALL): Use the new macros.
12112 Use -o rather than --output, since "missing" does not grok --output.
12114 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12116 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12117 comments do not always work. Never trust the exit status of
12120 2002-07-24 Kevin Ryde <user42@zip.com.au>
12122 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12123 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12125 2002-07-23 Paul Eggert <eggert@twinsun.com>
12127 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12128 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12129 apparently treats PATH="nonexistent" as if it contained ".".
12130 Bug reported by Stefan `Sec' Zehl.
12132 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12134 * doc/autoconf.texi (Limitations of Make): Mention the special

12394 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
12396 2002-05-17 Paul Eggert <eggert@twinsun.com>
12398 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12399 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12400 This improves on an earlier suggestion by H. Peter Anvin.
12402 2002-05-16 Paul Eggert <eggert@twinsun.com>
12404 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12405 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12406 Both macros now accept an optional source-dir arg.
12407 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12409 * NEWS: Document this.
12410 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12412 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12413 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12414 not for GNU extensions; this undoes part of the 2000-11-03 change,
12415 reverting to 2.13-compatible behavior.
12416 Add new optional argument DIR.
12417 (AC_FUNC_FNMATCH_GNU): New macro.
12419 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12421 2002-05-08 Paul Eggert <eggert@twinsun.com>
12423 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12424 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12425 and it causes a 'test' syntax error if it fails.
12426 Bug reported by Stephen Gildea.
12428 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12429 If prototypes are supported, use them to check this at compile-time,
12430 instead of trying to check it at run-time. If we must do a run-time
12431 check, assume that setvbuf is standard when cross-compiling, as
12432 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12433 Bug reported by Paul D. Smith.
12435 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12436 argument specifying location of getloadavg.c. This removes a
12437 FIXME. This idea was taken from Jim Meyering's implementation in
12439 * doc/autoconf.texi (Particular Functions): Document this.
12440 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12441 that's what the code does; this fixes a bug reported by
12444 2002-05-03 Akim Demaille <akim@epita.fr>
12446 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12447 autopoint instead of gettextize.
12448 ($uses_alocal): Rename as...
12449 ($uses_aclocal): this.
12450 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12451 Suggested by Bruno Haible.
12453 2002-05-03 Akim Demaille <akim@epita.fr>
12455 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12457 2002-04-29 Paul Eggert <eggert@twinsun.com>
12459 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12460 files to be 1 second older; just set them to be the same time.
12461 Also, sleep 1 second after the first aclocal, to work around
12462 problems with sub-second time stamps on the input files.
12464 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12466 * doc/autoconf.texi: Mention "set -e -x" lossage
12467 under node "Limitations of Builtins".
12469 2002-04-29 Akim Demaille <akim@epita.fr>
12471 * doc/install.texi: Better wording for setting variables when
12473 From Christian Cornelssen.
12475 2002-04-29 Akim Demaille <akim@epita.fr>
12477 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12478 of lack of $LINENO support, then the test will compare the $LINENO
12479 in testsuite vs. the lineno in the test file. This is wrong, of
12481 Be sure to protect it.
12482 Reported by Patrick Welche.
12484 2002-04-25 Akim Demaille <akim@epita.fr>
12486 * doc/autoconf.texi (Obsolete Macros): Typo.
12487 Reported by Vladimir Volovich.
12489 2002-04-25 Akim Demaille <akim@epita.fr>
12491 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12492 than some of the input files, hence, on the second run of aclocal,
12493 if some of its input are younger, make them older.
12494 Suggested by Paul Eggert.
12496 2002-04-25 Akim Demaille <akim@epita.fr>
12498 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
12499 Thanks to Paul Eggert.
12501 2002-04-25 Akim Demaille <akim@epita.fr>
12503 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12504 and ac_subst_vars be sh variables containing the list of
12505 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12507 (_AC_INIT_PREPARE): Use them to log them.
12508 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12509 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12510 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12511 _AC_SUBST_FILES and _AC_SUBST_VARS.
12512 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12514 2002-04-24 Akim Demaille <akim@epita.fr>
12516 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12517 autoheader, so that automake does not complain about a missing
12518 config.h.in that was to be created.
12520 2002-04-23 Akim Demaille <akim@epita.fr>
12522 * bin/autoheader.in (parse_args): --warning takes an argument.
12525 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
12527 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

12572 Minor spelling and grammar fixes.
12574 * doc/autoconf.texi: Follow the outline suggested in the GNU
12575 Sample Texts sections of the Texinfo 4.2 manual. Most
12576 importantly, this makes sure that the copyright notices appear in
12577 all output formats. You probably need Texinfo 4.2 to generate

12618 From Oliver Kiddle and Peter Stephenson.
12620 Have M4sh perform minimal shell sanitizing.
12622 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12624 (_AS_PREPARE): this new macro.
12626 (AS_INIT): Invoke AS_SHELL_SANITIZE.

12629 Adjust Autoconf and Autotest.

12640 * tests/wrapsh.as: New, precursor of wrapsh.in.

12642 on Autotest and M4sh.

12678 Use dnl, not the KILL diversion.
12680 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12681 (AC_CONFIG_LINKS): here.
12683 Don't use the KILL diversion, as it kills spurious output, which
12684 results in failures being hidden.
12685 Use m4_defn where appropriate.
12686 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12687 after the second argument.
12689 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12690 syntax, as it is provided by M4sugar.

12735 2002-03-27 Paul Eggert <eggert@twinsun.com>
12737 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

12755 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

12758 about VPATH, overriding of macros in sub-makes, and handling of

12763 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12764 problem with here-document buffer boundaries.
12766 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12767 when reinvoking the shell, to work around problems with installers
12768 who put strange things like "cd" commands in their environments.

12793 (Limitations of Usual Tools): Add mkdir section.
12795 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12796 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12797 back on AS_DIRNAME to compute prefixes otherwise; this is
12798 roughly what mkinstalldirs does. That way, we need not have
12799 our own filename disassembler. The old disassembler did not
12800 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12802 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12803 Create at_test_all by a series of assignments,
12804 not by a single assignment of a long string. The latter causes ksh
12805 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12806 presumably because of a buffer overrun.
12808 2002-03-14 Paul Eggert <eggert@twinsun.com>

12811 Renamed from at_times. Now a boolean.

12813 says 'times: not found'.

12896 2002-03-04 Akim Demaille <akim@epita.fr>
12898 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
12901 2002-03-04 Akim Demaille <akim@epita.fr>
12903 * doc/autoconf.texi (Transforming Names): Equality between target
12904 and host is irrelevant.
12905 (Specifying Names, Canonicalizing): Remove all references to the
12906 backward compatibility hooks. Rather, collect them all into...
12907 (Hosts and Cross-Compilation): this new section.
12908 * doc/install.texi (System Type): Ditto.
12909 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12910 that `--host' implies cross-compilation.
12912 2002-03-04 Akim Demaille <akim@epita.fr>
12914 * doc/autoconf.texi (Evaluation Macros): New.
12915 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12917 (_m4_foreach): Define the variant with immediate evaluation so
12918 that it contains exactly the items, not an expression which
12919 evaluation is the current item.
12920 (m4_re_string, m4_re_word): Don't over quote them.
12922 2002-03-04 Akim Demaille <akim@epita.fr>
12924 Instead of having stacking `shift's evaluated at the end, let
12925 `foreach' loops immediately evaluate them.
12927 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12928 $*. This is the n-th time I change my mind, but hopefully this is
12931 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12933 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12934 it was only a hack for m4_text_wrap.
12935 (m4_car2): Remove, replaced by...
12937 (_m4_foreach): Adjust.
12938 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12939 m4_bpatsubst for clarification.

12991 AC_PREFIX_PROGRAM fails with dashed program names
12993 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

13012 sure not to introduce newlines in at_groups.

13027 cross-compilers, too. This undoes some of the most recent change
13030 2002-02-05 Akim Demaille <akim@epita.fr>
13032 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
13033 to make sure they are up to date when `check' is run.
13035 2002-02-05 Akim Demaille <akim@epita.fr>

13054 * bin/autom4te.in (&parse_args): Implement `frozen files are
13055 optional are the sum of the previous files on the command line'.
13056 Also, pass `--reload-state=' on them, so...
13057 (handle_m4): don't.
13058 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13059 (M4sh): Rely on M4sugar.

13097 2002-01-28 Akim Demaille <akim@epita.fr>
13099 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13100 AUTOTEST_PATH *after* it was set.
13101 Don't put `.' in the PATH: the user should be precise and `./' if
13102 needed. In addition, given that the test suite does some `cd', if
13103 `.' is in the path, the `tested programs' sections will report
13104 programs found in the test suite's directory, while during the
13105 tests (performed in their own directory), these programs are no
13106 longer visible. In other words, the results is confusing and
13108 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

13152 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13153 message on invalid options.
13154 * bin/autom4te.in (parse_args): Don't use
13155 Autoconf::General::getopt with non valid options.
13157 2002-01-17 Jim Meyering <meyering@lucent.com>
13159 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13160 $ac_cv_exeext so we don't use an old, invalid, cached value.

13174 package.m4, since is really depends upon configure.ac, not
13176 * doc/autoconf.texi (testsuite Scripts): Adjust.
13177 * tests/Makefile.am (package.m4): New.
13178 EXTRA_DIST it since its a source.
13180 2002-01-06 Akim Demaille <akim@epita.fr>
13182 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13183 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13184 and PACKAGE_BUGREPORT from here...
13185 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13187 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13188 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13189 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13190 * tests/tools.at (autoheader): Adjust.

13210 * doc/autoconf.texi (New Macros): Tweak wording.
13212 2001-12-14 Akim Demaille <akim@epita.fr>
13214 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13215 trailing files, don't apply `-rf' to files which might not be
13216 created by configure (core, core.*, and *.core), but just `rm -f'.
13217 Suggested by Jonathan Kamens.
13219 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13221 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

13243 2001-12-12 Kevin Ryde <user42@zip.com.au>

13246 forbidden file descriptors table.
13248 2001-11-26 Akim Demaille <akim@epita.fr>
13250 * bin/autoscan.in (%c_keywords): Build it at top level.
13251 Map to 1 in order to simplify its uses.

13255 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13256 Remove $filepath, useless.
13257 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13258 variables, they are really part of the tokens.
13259 Split the input line on spaces and then look for tokens.
13260 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13261 because of `lex$U.$(OBJEXT)'.
13262 (&scan_files): Use "@list" instead of join.

13268 Remove, replaced by...
13269 * tests/wrappl.in: Be common for all the Perl executables.
13270 In particular autoscan and autoheader want -I.
13271 * configure.ac: Adjust.
13272 * lib/autoscan/headers: errno.h is portable.
13274 2001-11-26 Akim Demaille <akim@epita.fr>
13276 * bin/autoscan.in (used): New.

13301 Test groups are now run two directories deeper.

13306 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13307 top_srcdir, builddir and top_builddir.
13308 Use `at_*dir' relatively to the directory containing the
13309 suite, use `*dir' when relatively to the current group dir.

13318 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13320 * doc/autoconf.texi (Using System Type): Add an example of `case
13321 $host' usage so people quit using `case $target' everywhere.
13323 2001-11-22 Akim Demaille <akim@epita.fr>
13325 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13326 spotted by Jim Meyering.
13328 2001-11-16 Paul Eggert <eggert@twinsun.com>
13330 This patch implements a `long double' suggestion by Oliver Kiddle.
13332 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13333 static, to catch errors if the value isn't known at compile-time
13334 and the compiler supports dynamic arrays. Change its name from
13335 `_array_' to `test_array' to avoid potential name clashes.
13336 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13337 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13338 better than double. Catch a bug in GCC 2.95.2 x86.
13339 * doc/autoconf.texi (C Compiler): Document the above.
13342 2001-11-13 Akim Demaille <akim@epita.fr>
13344 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by

13348 2001-11-13 Akim Demaille <akim@epita.fr>
13350 * lib/autotest/general.m4 (AT_INIT): After having run the test
13351 group, go back to the initial directory, not to at_suite_dir.
13353 2001-11-13 Akim Demaille <akim@epita.fr>
13355 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13356 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13357 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13359 (AT_CHECK_CONFIGURE): Use absolute paths.
13360 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13361 The problem is still the old one: there is no means in M4 (that I
13362 know about) to create a defining macro, because there is no means
13363 to create `$1' etc., therefore, the defining macro ``swallows''
13364 all the arguments meant to the defined macro.
13366 2001-11-13 Akim Demaille <akim@epita.fr>
13368 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.

13375 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13376 variable names when referring to a single test group, or to
13377 `suite' when referring to the whole test suite.
13378 `at_last_test' is removed: m4 compute at_format itself.
13379 (at_stdout, at_stder1, at_stderr): New variables.
13380 (AT_CHECK): Use them.
13382 2001-11-13 Akim Demaille <akim@epita.fr>
13384 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13386 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13387 Do it as soon as a test fails, don't wait till the end of the test
13389 Don't remove $as_me.[0-9]*, since these files no longer exist.
13391 2001-11-13 Akim Demaille <akim@epita.fr>
13393 * tests/tools.at: Use absolute paths, since we are no longer run
13396 2001-11-13 Akim Demaille <akim@epita.fr>
13398 Now that tests are running in their own private dir, there is no
13399 need to list the files to remove at the end of tests groups.
13401 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13402 (AT_data_files, at_data_files): Remove.
13403 (AT_CLEANUP, AT_DATA): Simplify.
13405 Remove the group dir if !debug && !failed.
13406 * tests/atspecific.m4: Adjust.
13408 2001-11-13 Akim Demaille <akim@epita.fr>
13410 Start a new layout for Autotest: `testsuite' creates
13411 `testsuite.dir' in which the at-check-line etc. files are to be
13412 found, and `testsuite.dir/003' where the test group 3 is run.
13414 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13415 at_check_line_file, at_format, at_test_normalized, at_group_dir
13417 Create the directories.
13418 Use absolute paths for at- files.
13419 (AT_CHECK): Adjust.
13421 2001-11-11 Michael Matz <matz@kde.org>
13423 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13425 (m4_car): Properly quote arguments.
13427 2001-11-13 Akim Demaille <akim@epita.fr>
13429 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13430 with stricter rules on LIBOBJS.
13432 2001-11-12 Paul Eggert <eggert@twinsun.com>
13434 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13435 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13438 2001-11-12 Akim Demaille <akim@epita.fr>
13440 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13442 2001-11-12 Akim Demaille <akim@epita.fr>

13447 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13448 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13449 specify to what the macro should be defined (typically to 1).
13451 2001-11-12 Akim Demaille <akim@epita.fr>
13453 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13456 2001-11-12 Akim Demaille <akim@epita.fr>
13458 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13459 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13460 definition used by Automake where LEX is +/- "${missing} lex" and
13461 `missing' itself contains variables.
13463 2001-11-12 Akim Demaille <akim@epita.fr>
13465 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13466 Now that M4sh pushes BODY, the comments were output at the end of
13469 2001-11-08 Akim Demaille <akim@epita.fr>
13471 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13472 that we can trace macros from aclocal.m4.
13473 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13474 obsoleted, and redirect to the former anyway.
13475 Reported by Ralf Corsepius.
13477 2001-11-08 Akim Demaille <akim@epita.fr>
13479 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13480 processed only if present.
13481 * tests/torture.at (Configuring subdirectories): Use autoreconf
13482 instead of successive calls to autoconf.
13483 Add a nonexistent subdirectory to exercise the patch above.
13484 Reported by Ralf Corsepius.
13486 2001-11-08 Kevin Ryde <user42@zip.com.au>
13488 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13489 doesn't accept .S files.

13495 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13496 * bin/autom4te.in (warn_forbidden): New.
13497 (handle_output): Use it.
13498 Read m4_pattern_forbid with messages.
13500 2001-11-05 Akim Demaille <akim@epita.fr>
13502 * bin/autom4te.in (--normalize): Remove.
13503 * lib/autom4te.in: Adjust.
13505 2001-11-05 Akim Demaille <akim@epita.fr>
13507 * tests/Makefile.am (testsuite): Rename this target as...
13508 ($(TESTSUITE)): this.
13511 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13513 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13514 the --prefix option, also remove it's argument.
13516 2001-11-05 Akim Demaille <akim@epita.fr>
13518 * doc/autoconf.texi (testsuite Invocation): Update.
13519 (Writing testsuite.at): Update.
13521 2001-11-03 Akim Demaille <akim@epita.fr>
13523 * doc/autoconf.texi: s/@code/@command/ where appropriate.
13525 2001-11-03 Akim Demaille <akim@epita.fr>
13527 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13528 (&file_name_is_absolute): New, wrappers around routines from
13530 Use and export them.
13531 (&find_configure_ac): Optionally take a directory where to look at.
13532 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13534 Default @ARGV to `.', not find_configure_ac.
13535 (&autoreconf): Argument is a directory.
13536 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13537 * doc/autoconf.texi (autoreconf Invocation): Update.
13539 2001-11-03 Akim Demaille <akim@epita.fr>
13541 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13542 (@export_forward_subs): New.
13543 Add basename, dirname, and fileparse.
13545 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13546 Don't look for aclocal flags if we already know aclocal is not
13548 Move aclocal.m4t only if it exists.
13549 Reported by Ezra Peisach.
13551 2001-11-03 Akim Demaille <akim@epita.fr>
13553 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13554 passed on command line, defaulting to ./configure.ac if present.
13555 (&maybe_autoreconf, File::Find): Remove, unused.
13556 (&autoreconf): If autoconf is not used, don't try to trace.
13558 2001-11-02 Akim Demaille <akim@epita.fr>
13560 * configure.ac: Bump to 2.52g.
13562 2001-11-02 Akim Demaille <akim@epita.fr>
13566 2001-11-02 Akim Demaille <akim@epita.fr>
13568 * config/config.guess, config/config.sub, doc/standards.texi:
13569 * config/lispdir.m4: Update from masters.
13570 * configure.ac: Bump to 2.52f.
13572 2001-11-02 Akim Demaille <akim@epita.fr>
13574 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13575 Don't run aclocal when aclocal.m4 is not from aclocal.
13577 Don't run libtoolize and gettextize if --install is not given.
13579 2001-11-01 Paul Eggert <eggert@twinsun.com>
13581 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13582 be invoked before _AS_LINENO_PREPARE.
13583 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13584 than character ranges.
13586 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13587 invoking AS_BASENAME. Set the locale variables to 'C' if
13588 possible, as POSIX requires this to get the traditional
13590 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13592 2001-10-31 Paul Eggert <eggert@twinsun.com>
13594 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13595 with {}, as that triggers a bug in Bash 2.05.
13597 (_AS_LINENO_PREPARE): Use Sed rather than
13598 Awk. Fix the sed prepass to work even if there are multiple
13599 instances of $LINENO on the same line. Do not substitute for
13600 other variables like $LINENOT. Do not check file dates; such a
13601 check is unreliable on sufficiently fast machines, and removing
13602 the check makes the code simpler and more reliable. Check for
13603 output and chmod failures.
13605 * doc/autoconf.texi (Special Shell Variables): Document
13608 2001-10-31 Akim Demaille <akim@epita.fr>
13610 * tests/Makefile.am (atconfig): Remove this target, Automake
13613 2001-10-31 Akim Demaille <akim@epita.fr>
13615 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13616 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13617 provided, while it is optional.
13618 * configure.ac: Adjust.
13620 2001-10-26 Paul Eggert <eggert@twinsun.com>
13622 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13623 lib/Autom4te/Struct.pm:
13624 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13627 * doc/autoconf.texi (Special Shell Variables): Document some
13628 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13630 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13631 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13632 eval $LINENO is not portable in practice.
13634 2001-10-24 Akim Demaille <akim@epita.fr>
13636 * lib/Autom4te/General.pm (backname): New.
13638 2001-10-24 Akim Demaille <akim@epita.fr>
13640 * m4/: Remove, merged into...
13643 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
13645 * doc/autoconf.texi (Shellology): Mention the problems with bash
13646 2.05's use of ANSI quoting in its `set' builtin.
13648 2001-10-22 Paul Eggert <eggert@twinsun.com>
13650 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13651 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13652 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13653 POSIX decided to standardize on the int flavor of strerror_r.
13654 Always do char* test, as there's no reason not to.
13655 Assign to a char* var, to catch strerror_r that returns int*.
13657 * doc/autoconf.texi (Particular Functions):
13658 Document the above changes. Also, document the fact that
13659 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13661 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13663 2001-10-20 Akim Demaille <akim@epita.fr>
13665 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

13668 2001-10-20 Akim Demaille <akim@epita.fr>
13670 * lib/Autom4te/General.pm (&update_file): If destination is
13671 unchanged, remove the source.
13672 (&up_to_date_p): Don't be verbose, be debug.
13673 * bin/autoreconf.in: No longer support --m4dir.
13674 (&autoreconf): Display the full path of the configure.ac we are
13676 Trace it only once.
13677 Be sure to honor --force with gettextize.
13678 Always run aclocal.
13679 * doc/autoconf.texi: Adjust.
13681 2001-10-20 Akim Demaille <akim@epita.fr>
13683 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13685 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13686 `intl' is already present, as it refuses unless --force.
13687 (&parse_args): Use -I, --include instead of the old Autoconf
13689 ($localdir, $autoconf_dir): Remove.
13691 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13693 2001-10-19 Jens Petersen <petersen@redhat.com>
13695 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

13705 2001-10-19 Akim Demaille <akim@epita.fr>

13711 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
13713 * bin/autoreconf.in (autoreconf): Display the path to the
13714 configure.ac being studied.
13716 2001-10-18 Paul Eggert <eggert@twinsun.com>
13718 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13719 long, to work around a bug in the HP C compiler version HP92453-01
13722 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13723 (AS_BASENAME_EXPR): New macro.
13724 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13725 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13726 and fall back on 'sed' only if the other two fail. This makes
13727 AS_BASENAME act more like AS_DIRNAME.
13728 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13729 contains white space.
13730 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13731 Use AS_DIRNAME, since I think it's now DOS-friendly.
13732 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
13733 Allow "dirname //FOO" to return either / or //, as POSIX allows
13736 2001-10-10 Akim Demaille <akim@epita.fr>
13738 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

13744 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
13745 m4_define, since...

13782 (Syntax of the shell scripts): Don't.

13873 shell does not support LINENO, and if CONFIG_SHELL is unset or
13874 empty, and if we can find a shell that does support LINENO,
13875 then set CONFIG_SHELL to that shell and then re-execute
13876 ourselves with CONFIG_SHELL.
13878 2001-10-05 Paul Eggert <eggert@twinsun.com>
13880 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
13881 doesn't exist. Remove *.tmp, as a .tmp file is created during the

13923 compatibility with POSIX shells.

13952 Don't use nested parenthesization. This patch was originally
13953 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
13954 but somehow it didn't get incorporated then.

13962 Check for `expr' arithmetic overflow, and for compilation failure,
13963 and invoke a new argument $4 if either is discovered.
13964 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13965 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
13967 2001-09-28 Akim Demaille <akim@epita.fr>

14000 * doc/autoconf.texi (autoconf Invocation): Fix the example:
14001 AC_TRY_RUN is about compilation, not shell commands.

14044 Don't compute at_srcdir nor at_top_srcdir.
14046 * tests/tools.at: Hence use top_srcdir.
14048 * tests/Makefile.am, tests/autoconf, tests/autoheader,

14106 * tests/Makefile.am (package.m4): Remove.
14108 2001-09-22 Akim Demaille <akim@epita.fr>
14110 Rely on `$LINENO' when possible instead of `__oline__'.

14118 * lib/autoconf/programs.m4: Replace all the occurrences of

14129 2001-09-21 Akim Demaille <akim@epita.fr>
14131 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
14132 Suggested by Jim Meyering.
14134 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14136 * lib/autoconf/programs.m4: Use extensions listed in
14137 $ac_executable_extensions when looking for programs.

14166 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14168 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

14175 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14177 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14178 already have $file). Set output files to binary mode (helps avoid
14179 CR issues on DOSish systems).
14181 2001-09-19 Akim Demaille <akim@epita.fr>
14183 * lib/autotest/general.m4: Englishoes.
14184 From Tim Van Holder and Alexey Mahotkin.
14186 2001-09-18 Paul Eggert <eggert@twinsun.com>
14188 * doc/autoconf.texi (Common Shell Constructs): New node,
14189 documenting AS_DIRNAME.
14190 (Limitations of Usual Tools): Refer to it when discussing dirname.
14191 Also, update discussion of POSIX standard to reflect latest draft.
14193 * lib/autoconf/c.m4:
14194 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14196 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14197 Do not pass a first argument with leading '-'
14198 to expr, by parenthesizing initial integers that might be negative.
14200 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14201 now merely checks whether it is an error to pass an argument
14204 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14205 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14206 whether it is a (compile-time) error to pass an argument to
14207 getpgrp. This simpler test supports the revised documentation,
14208 and is all that AC_FUNC_GETPGRP's users really need.
14210 2001-09-18 Akim Demaille <akim@epita.fr>
14212 * doc/autoconf.texi (Limitations of Make) <$<>: New.

14222 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14224 Add test for AS_BASENAME.
14225 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14226 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14227 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14228 * tests/base.at: Fixed the expected responses. The old ones were
14230 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14231 the documentation claims it should (and how it behaved in 2.13).
14233 2001-09-18 Akim Demaille <akim@epita.fr>
14235 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14236 the AC_CONFIG_COMMANDS invocation.
14237 This also solves the name clash problems.
14238 Don't set the package's ID.
14239 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14240 No longer to be shipped.
14241 (version.in): Remove.
14242 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14243 * lib/autoconf/status.m4: Adjust.
14244 Use `m4_PACKAGE_STRING'.
14245 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14246 the only optional argument is the name of the test suite.
14247 Expect `package.m4' to define the package signature.
14248 * lib/autom4te.in (Autotest): Add `package.m4?'.
14249 * tests/Makefile.am (package.m4): New.
14250 * tests/suite.at: ifnames is a victim.
14252 2001-09-18 Akim Demaille <akim@epita.fr>
14254 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14255 AC_LIBSOURCE, AC_CONFIG_FILES.
14256 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14257 program version string doesn't match the package's.
14258 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14261 2001-09-17 Paul Eggert <eggert@twinsun.com>
14263 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14264 Allow expression to return any value that can fit into unsigned long
14265 (not int, as before). Check for output errors.
14267 2001-09-17 Bruno Haible <haible@ilog.fr>
14269 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14270 Always include <stdio.h> and <stdlib.h>. Evaluate
14271 the expression in an extra function before these includes. Call
14272 fprintf "%d" only after ensuring the argument is of type 'int'.
14273 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14275 2001-09-17 Paul Eggert <eggert@twinsun.com>
14277 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14278 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14279 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14280 when they don't exist.
14282 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14283 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14286 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14287 version with the version used by fileutils 4.1, except use
14288 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14291 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14293 2001-09-13 Akim Demaille <akim@epita.fr>

14301 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
14302 m4_defn'ing is valid.

14317 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
14319 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
14320 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
14321 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
14322 AT_tests_all for consistency.
14324 (AT_VICTIMS): Similar to AT_KEYWORDS.

14329 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
14331 2001-09-13 Akim Demaille <akim@epita.fr>
14333 * lib/autotest/general.m4 (AT_INIT): Create and remove
14334 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14335 test suites can cohabit.
14337 2001-09-13 Akim Demaille <akim@epita.fr>

14448 the maintainer is dumb enough to do that...
14450 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14451 excellence in M4 quotation: consider `__file__' is active.

14524 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

14631 find the executables for it.

14633 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14635 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14636 indeed related to running the test suite, while passing
14637 --autoconf-dir and others is related to running non installed
14638 Autoconf executables. So don't do that, leave it to...

14640 * tests/autoscan: New.
14641 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

14660 2001-08-29 Akim Demaille <akim@epita.fr>

14818 (AMTAR): Help automake define it.
14819 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
14820 needed, 1.5 can have a macro and a target with the same name.

15049 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

15067 * doc/autoconf.texi: Work around Texinfo buglets.
15068 (Transformation Rules): One example is enough, users are expected

15074 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

15130 2001-08-15 Akim Demaille <akim@epita.fr>
15132 * bin/autom4te.in (@m4_warning): New.
15133 (&handle_m4): Use it.
15134 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

15204 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15206 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15207 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15208 * doc/autoconf.texi (C Compiler Characteristics): Update
15209 documentation for AC_C_BIGENDIAN.
15211 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15213 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15214 magic values from an object file when cross-compiling.
15215 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15217 2001-08-10 Akim Demaille <akim@epita.fr>
15219 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15221 Suggested by Russ Allbery.
15223 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15225 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15226 current $prefix to the sub-configures.
15228 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15230 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15231 extension (needed on BeOS). Reported by Guido van Rossum.
15233 2001-08-09 Akim Demaille <akim@epita.fr>
15235 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15237 2001-08-07 Akim Demaille <akim@epita.fr>
15239 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15241 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15242 No need to remove the files before and after the each test, before
15243 each test and at the end of the suite is enough.
15244 Display only the children `times', not the shell's.
15245 If the test failed or was skipped, at-times is not available.
15247 2001-08-07 Akim Demaille <akim@epita.fr>
15249 Always produce testsuite.log, including when there are no
15250 failures. This helps getting information on skipped tests, and
15251 duration of the tests. Err, implement the latter btw.
15253 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15254 Dump information on the first run of each test.
15255 (AT_CLEANUP): Create `at-times' containing the duration of the
15258 2001-08-07 Akim Demaille <akim@epita.fr>
15260 The use of `dumpstat' revealed that `len' was used although it
15261 should not. m4_text_wrap was using it, but in the Autoconf world
15262 where it is legal. Hence (i) test M4sh in its own world, not
15263 Autoconf's, and (ii), ahem, fix the bug :)
15265 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15266 does not like `' instead of [].
