1259 Cover more potentially problemtic file names. Use the new
1260 functions.
1262 Properly handle funny file names for headers in config.status.
1263 The test suite did not cover this bug because the code was not
1264 quoting properly the arguments of `rm -f' (which "fails" silently)
1265 as well as the arguments of `diff' (whose output was redirected to
1266 /dev/null so we couldn't see its error message).

1474 * tests/tools.at (autom4te and whitespace in file names): Restore
1475 font-lock. Create $TMPDIR before it might be used.
1477 Fix spurious testsuite failure with M4 1.4.11.
1478 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1480 Optimize AC_REQUIRE.
1481 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1482 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1483 (m4_require): Avoid extra macro calls.
1485 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1487 * tests/torture.at (srcdir): Fix quoting.
1489 Do not pass top_srcdir to configure scripts in testsuite.
1490 * tests/autotest.at (srcdir propagation): Copy install-sh to
1491 source tree.
1492 (my only test): Drop setting of `top_srcdir'.
1493 * tests/base.at (Input/Output): Likewise.
1494 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1495 config.guess, and config.sub to test source tree.
1496 Drop AC_CONFIG_AUX_DIR setting.
1497 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1498 * tests/torture.at (Substitute a 2000-byte string): Drop
1499 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1500 (Substitute a newline, datarootdir workaround): Likewise.
1501 (Define a newline): Adjust for linenumber changes in configure.ac.
1502 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
1504 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
1505 if `pwd` contains whitespace.
1507 Quote $abs_top_srcdir in tests.
1508 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1509 * tests/tools.at (Syntax of the shell scripts): Likewise.
1511 * tests/m4sh.at (LINENO): Quote $0.
1513 Fix testsuite program wrapper for whitespace in `pwd`.
1514 The problem here is that the usual mantra is that command
1515 variables can contain arguments, thus we cannot just escape
1516 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1517 $top_builddir/tests directory early in $PATH, so that the
1518 wrappers are found by their plain name.
1519 * tests/wrapper.as: Put $testdir early in $PATH.
1520 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1522 Proper config.status --file/--header and $srcdir escaping.
1523 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
1524 characters in $ac_file_inputs.
1525 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
1526 accordingly.
1527 * tests/torture.at (datarootdir workaround): Adjust.
1528 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
1530 Fix Autotest for whitespace in `pwd`.
1531 * lib/autotest/general.m4 (AT_INIT)
1532 <at_func_create_debugging_script, Driver Loop>:
1533 Quote $at_group_dir.
1534 * tests/autotest.at (whitespace in absolute testdir): New test.
1536 * lib/autom4te.in: Quote @datadir@.
1538 Proper file name escaping in Autoconf programs and Perl modules.
1539 This includes escaping of characters special to the shell
1540 as well as special to Perl, e.g., leading `<' or `>'.
1541 For example, when $file starts with `>', `open ">$file"'
1542 wrongly tries to append to a different file.
1543 * bin/autoconf.as: Fix quoting for autom4te options.
1544 * lib/Autom4te/General.pm (shell_quote): New function, taken
1545 from coreutils, written by Jim Meyering.
1546 (mktmpdir): Use it.
1547 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1548 and open_quote.
1549 * bin/autoreconf.in (parse_args): Likewise.
1550 * bin/autoscan.in (main): Likewise.
1551 * bin/autoupdate.in (main): Likewise.
1552 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1553 * bin/ifnames.in: Likewise, XFile usage fixes.
1554 * tests/tools.at (autom4te and whitespace in file names): Extend
1555 test. Test twice, with special characters allowed on w32, and the
1556 rest. Test leading and trailing whitespace, for `open_quote'.
1557 (autotools and whitespace in file names): New, analogous test.
1558 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1559 by Russ Allbery and Eric Blake.
1561 Sync from Automake.
1562 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1563 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1564 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1565 (update_file, contents): Use it.
1567 * Makefile.am (autom4te-update): Rewrite for git.
1569 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1571 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1573 Fix copyright years.
1574 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1575 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1577 2007-12-04 Eric Blake <ebb9@byu.net>
1579 Manually resync with gnulib, since 'make cvs-update' no longer works.
1580 * build-aux/config.guess: New upstream version.
1581 * build-aux/config.sub: Likewise.
1583 When using older automake, don't downgrade build-aux/texinfo.tex.
1584 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1585 * doc/Makefile.am (TEXINFO_TEX): Add.
1587 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1589 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1590 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1591 #undef as this runs afoul of our new way of creating config.h.
1592 Problem reported by Jim Meyering in
1593 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

1597 Fix autom4te for unusual characters in input file names.
1598 * bin/autom4te.in (files_to_options): Quote active characters
1599 for the shell.
1600 * tests/tools.at (autom4te and white space in file names):
1601 New test.
1603 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1604 Document that Tru64 awk always splits $0.
1606 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1608 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1609 `#AT_STOP_...' line at the end of each test.
1611 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1613 * lib/autotest/general.m4 (AT_INIT): For awk line number
1614 extraction script, ensure `$at_group' has a defined value
1615 even for the empty set, and properly quote its usage inside
1616 the awk script.
1618 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1620 * doc/autoconf.texi (Shell Functions): New chapter. Document
1621 IRIX sh $0 issue in functions, move content from ...
1622 (Portable Shell): ... here.
1623 (Shell Script Compiler): Note that shell functions are not
1624 totally unportable any more.
1626 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1627 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1629 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1630 extracting the line numbers of the last needed test.
1632 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1634 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1635 Fix quoting.
1637 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1639 Fix IRIX testsuite debugging failures: $0 in functions.
1640 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1641 Do not use $0 inside a function, as IRIX sh will set that to the
1642 function name rather than the script invocation name.
1644 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1645 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1647 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1648 to extract test scripts.
1649 (AT_INIT): Extract and cache test script line numbers.
1651 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1653 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1654 subsequent fixups; the awk -> here-document conversion trashes
1655 performance too much with AIX sh.
1657 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1659 * tests/local.at: Do not test m4, perl with AT_TESTED.
1661 Diagnose and guard against write errors dealing with config.status.
1662 The general idea is this: all write failures from `configure'
1663 writing `config.status' are indicated by $ac_write_error, which
1664 is only checked at the end. This is safe because config.status
1665 code is not executed before the file is complete. Other write
1666 failures, be they inside config.status, or in sub shell/awk
1667 scripts spawned from configure or config.status, typically need
1668 earlier checking, as their results are used right afterwards.
1669 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1670 before writing config.status, check afterwards.
1671 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1672 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1673 Set `ac_write_error' for write failures to config.status. Barf
1674 upon write failures to temporary files.
1675 Adjust note about closing and reopening the here-document.
1676 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1677 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1678 reopening the here-document.
1679 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1680 Ensure `ac_write_error' does not escape into config.status.
1681 Also, add a couple of code paths not yet exercised in the test
1682 suite: a config file with input from stdin, and a config header
1683 output to stdout.
1684 Suggestion for catching write errors by Bruno Haible.
1686 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1688 Avoid error with Tru64 awk and testsuite lines with many words.
1689 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1690 reads the testsuite, set the field separator to an unusual value,
1691 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1692 even splits the input if $i, i>0, was never accessed in the script.
1694 Revert 2007-10-17 change.
1695 * TODO: Multiline args in config files and headers mean something
1696 different and are not fixed, see
1697 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
1698 Report by Stepan Kasal.
1700 * doc/autoconf.texi (Generic Programs): Fix typo.
1702 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1704 AC_*_TOOL does not canonicalize the prefix
1705 * doc/autoconf.texi (Generic Programs): Do not say that
1706 the *_TOOL macros canonicalize, they simply use the `host_alias'.
1708 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1710 Diagnose write errors in config.status instantiations.
1711 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
1712 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
1713 on write errors.
1714 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1715 Extend test to also check for some write error failures, using...
1716 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
1717 Report by Bruno Haible.
1719 Indentation fixups.
1720 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
1721 indentation.
1722 (_AT_CHECK): Use less indentation, to save space.
1724 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1726 Add witness macro for @top_build_prefix@ substitution.
1727 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
1728 (_AC_OUTPUT_FILE): Mention it here.
1730 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
1731 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1733 * lib/autotest/general.m4 (at_func_test): Remove.
1734 (AT_INIT): Pre-extract test groups into separate files.
1735 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
1736 Remove at-test-source files together with the $at_group_dir.
1737 * tests/autotest.at (Long test source lines): New test.
1739 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1741 Shell functions and variables may share a namespace.

1745 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
1747 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
1748 gnulib.
1750 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1752 * lib/autoconf/status.m4: Fix a couple of comment typos.
1754 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1756 2007-11-13 Jim Meyering <meyering@redhat.com>
1758 Clean up the rule to create "expr".
1759 * tests/Makefile.am (expr): Don't redirect directly to target.
1760 Redirect just once, not for each echo statement.
1761 Use $@, not literal "expr".
1763 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1765 Don't worry about preprocessor when testing long long.
1766 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1767 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1768 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1769 These no longer check for preprocessor flaws.
1770 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1771 Do not check for preprocessor flaws.
1773 2007-11-13 Jim Meyering <meyering@redhat.com>
1775 Adapt dependencies, now that a version change doesn't modify configure.ac
1776 * GNUmakefile: Remove "make clean" kludge.
1777 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1778 configure.ac.
1779 Don't redirect directly to target.
1780 Use $@, not literal "version.m4".
1782 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1784 * doc/autoconf.texi (Making testsuite Scripts): Document
1785 ":;{" shorthand as in previous patch.
1787 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1789 * doc/autoconf.texi (Limitations of Builtins): Document problem
1790 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1791 for the workaround.
1792 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1793 Use ":;{" shorthand.
1794 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1796 2007-11-12 Jim Meyering <meyering@redhat.com>
1798 Add more non-srcdir build support.
1799 * GNUmakefile (dummy): Split a long line.
1800 Add -v option to autoreconf invocation.
1802 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1803 * GNUmakefile (dummy): Remove INSTALL.
1805 Remove racy commands to build scripts in bin/ and tests/.
1806 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1807 are guaranteed to be built, remove the rules that tried to build
1808 them. Before, with a parallel build, these rules could lead to
1809 two processes writing tests/wrapper.in concurrently.
1811 Build in man/ only *after* building in bin/ and tests/.
1812 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1813 in both bin/ and tests/.
1815 Accommodate non-srcdir build-from-checkout.
1816 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1817 Use git's --git-dir=$srcdir/.git option.
1818 Add quotes, in case tarball_version_file contains shell meta-characters.
1819 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1820 * configure.ac: Pass "." to git-version-gen.
1822 Avoid spurious test failures due to version skew.
1823 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1825 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1827 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.

1850 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1852 Ignore configure --help* errors due to LINENO-impaired shells.
1853 * tests/torture.at (Configuring subdirectories, Deep Package):
1854 In the --help* tests in read-only trees, make `.' temporarily
1855 writable again for the `stderr' file, and ignore errors due to
1856 the attempt to write configure.lineno.
1857 Report by Patrick Welche.
1859 2007-11-10 Jim Meyering <meyering@redhat.com>
1861 Generate package.m4 in build-dir, not srcdir.
1862 * tests/Makefile.am (package.m4): Adjust target.
1863 Don't redirect directly to $@.
1864 (CLEANFILES): Add package.m4.
1865 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1866 in $(srcdir).
1867 When running $(AUTOTEST), search "." before searching $(srcdir).
1869 Avoid a race condition that would make parallel "distclean" fail.
1870 * tests/Makefile.am (distclean-generic): Replace the default,
1871 automake-provided rule with an identical one, but with an additional
1872 dependency on distclean-local. Simply adding the dependency would
1873 cause automake not to emit the rule at all.
1874 * BUGS: Building with -jN works, now.
1876 Distribute git-version-gen.
1877 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1878 since GNUmakefile is distributed, and requires it for dist* rules.
1880 Remove two more generated files from version control.
1881 * INSTALL: Remove generated file.
1882 * lib/autoscan/autoscan.list: Remove generated file.
1884 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1886 * GNUmakefile (PATH): Remove stray apostrophes; they become
1887 part of PATH, which isn't wanted here.
1889 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1891 New config files output variable `top_build_prefix'.
1892 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1893 `top_build_prefix'.
1894 * doc/autoconf.texi (Preset Output Variables): Document it.
1895 * NEWS: Update.
1896 Report by Bob Friesenhahn.
1898 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1899 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1900 function, to parametrize arithmetic with expr vs. the shell.
1901 Use it where possible.
1902 Suggestion by Benoit Sigoure.
1904 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1906 Adjust the documentation of autotest WRT atlocal.
1907 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1908 when using Automake, to write a rule to produce atlocal, since it's
1909 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1910 distributed, not atconfig.in.
1912 2007-11-04 Eric Blake <ebb9@byu.net>

1933 Adjust the build procedure so "make check" works reliably.
1934 * README-hacking: Include an extra step between "make" and
1935 "make check" to ensure that the latter passes.
1937 Use just-built tools, when possible.
1938 * GNUmakefile (PATH): Set and export here, ...
1939 (dummy): ... rather than here.

2011 Make inter-release --version output more useful.
2013 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2014 which indicates that it is built using the 19th change set
2015 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2016 is a prefix of the commit SHA1.
2017 * build-aux/git-version-gen: New file.
2018 * configure.ac: Run it to set the version.
2019 (AM_INIT_AUTOMAKE): Don't check NEWS here.

2027 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
2028 git-version-gen doesn't match $(VERSION), but only for dist targets.

3284 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look

3304 for C++; this drops support for anonymous struct and union types,
3305 which were problematic anyway.
3306 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even

3324 with objects too. Document the restrictions on its use.
3325 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3326 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3327 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3328 works but the latter doesn't, then it's a valid type.
3329 This lets people use function types and so forth.
3330 For C++ there doesn't seem to be a simple solution, so leave it alone.
3331 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3332 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3333 AC_CHECK_TYPE; that wasn't documented or necessary.

3391 (Limitations of Usual Tools): Also list \< and \>, and mention that
3392 HP-UX's grep, like the one from Solaris, does not support that syntax.
3394 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3396 * doc/autoconf.texi (Specifying Names): `--host' does not
3397 change the build type.
3399 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3401 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
3402 suggests AC_CONFIG_HEADERS.

3421 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
3422 Reindent for sanity's sake.
3424 2007-02-24 Eric Blake <ebb9@byu.net>
3426 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
3427 copyright.

3435 status of rm so we know when it failed.
3436 If cleaning of test dir failed before running the test, warn.
3437 Output the line separator in verbose mode before the warning
3438 to make clear the warning belongs to the following test.
3440 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>

3455 carriage return.
3456 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
3457 with traditional Awk and begin.
3458 * tests/torture.at (Limitations of Builtins): Document the problem

3463 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
3465 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
3466 input from /dev/null in awk test, so even Solaris /usr/bin/awk

3501 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3503 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3504 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3505 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3506 substitution will still be done by the special code.
3507 Report by Jim Meyering.
3509 * doc/autoconf.texi (File System Conventions): Mention that
3510 $PATH_SEPARATOR is for the build system only.

3522 Report against Automake by Patrick Welche.
3524 2007-01-15 Stepan Kasal <kasal@ucw.cz>
3526 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
3528 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3530 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3531 early on the reader side, drop stderr of the input to avoid
3532 `broken pipe' error output; this may happen even with shell
3533 builtin `echo' of some bash versions. Reports by Ian Macdonald
3534 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3536 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3538 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
3539 separate items of `ac_user_opts', to avoid long lines.
3540 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
3542 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3546 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
3548 Fix some wording problems noted by Paolo Bonzini in:
3549 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3550 * doc/autoconf.texi (Signed Overflow Examples): Give more
3551 discussion about the allow_superuser_privileges example,
3552 and change it a bit to make things clearer.
3553 (Optimization and Wraparound): Clarify whether the compiler
3554 will generate an infinite loop for the example derived from
3555 Autoconf's mktime test.
3556 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3557 Also, clarify unsigned multiplication overflow.
3559 2007-01-04 Eric Blake <ebb9@byu.net>
3561 * bin/Makefile.am (RELEASE_YEAR): New macro.
3562 (edit): Use it to supply correct copyright year to scripts.
3563 * bin/autoconf.as (version): Use it.
3564 * bin/autoheader.in ($version): Likewise.
3565 * bin/autom4te.in ($version): Likewise.
3566 * bin/autoreconf.in ($version): Likewise.
3567 * bin/autoscan.in ($version): Likewise.
3568 * bin/autoupdate.in ($version): Likewise.
3569 * bin/ifnames.in ($version): Likewise.
3571 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3573 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3574 feedback. The most important changes document what happens when
3575 you convert an out-of-range value to a signed integer type, and
3576 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3577 a + b.
3579 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3580 rewrite, taking notions from the recent discussion on the gcc and
3581 autoconf mailing lists; please see
3582 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3583 and follow the many links.
3584 (Integer Overflow Basics, Signed Overflow Examples):
3585 (Optimization and Wraparound, Signed Overflow Advice):
3586 (Signed Integer Division): New sections.
3588 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3590 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3591 preprocessor macro arguments in traced name.
3592 * doc/autoconf.texi (Defining symbols): Document longstanding
3593 support for AC_DEFINE-ing macros with arguments, and document
3594 behavior when the same variable has multiple AC_DEFINEs.
3595 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3596 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3597 macros directly, giving much shorter and simpler code.
3599 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3601 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3602 space before "$ac_configure_args" to prevent a 'config.status
3603 --recheck' failure if ac_configure_args doesn't contain a leading
3604 space. This works around a problem with the XEmacs configure.ac,
3605 which uses the (undocumented) ac_configure_args variable
3606 inconsistently with Autoconf.
3608 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3610 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3611 Include <limits.h>, and use its INT_MAX to rewrite the
3612 j loop so that it does not overflow 'int'. Problem reported by
3613 Ralf Wildenhues in
3614 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3615 Play it safe by shifting left by 1 rather than multiplying by 2,
3616 as GCC is less likely to optimize this away when the value
3617 is signed (when it assumes overflow leads to undefined behavior).
3618 Also, don't assume time_t uses two's complement.
3620 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3622 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3623 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3624 dumps core on it. Report by Tim Rice.
3626 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3628 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3629 --disable-option-checking to --help output even when
3630 AC_PRESERVE_HELP_ORDER is not used.
3631 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3632 --with argument, rather than argument with [-.] replaced by
3633 underscores.
3634 * NEWS: Fix typo in previous change; the news was in the
3635 wrong section.
3637 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3639 * NEWS: Warnings are now generated by default for unknown
3640 --enable-* and --with-* options.
3641 * doc/autoconf.texi (Option Checking): Renamed from
3642 (Configure Option Checking). Tighten up the wording a bit.
3643 (External Software, Package Options): Cross-reference to Option
3644 Checking, and use this to shorten our section.
3645 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3646 "$x" to test "x$foo" != x.
3647 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3648 Don't warn if $enable_option_checking is "no".
3649 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3650 ac_unrecognized_opts to the empty string.
3651 Don't echo the unrecognized opts, as this might mishandle
3652 backslashes or leading -.
3653 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3654 usage next to the other --disable-FEATURE options in the
3655 help string.
3657 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3659 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3660 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3661 Print warning for unrecognized --with and --enable options
3662 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3663 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3664 Disable option checking when subdirs are configured.
3665 (AC_OUTPUT): If warnings are enabled, print warning about
3666 unrecognized --with and --enable options at the end of
3667 the configure output (as well as at the beginning).
3668 * doc/autoconf.texi (Option Checking): New node.
3669 Document new option warning functionality.
3671 2006-12-16 Eric Blake <ebb9@byu.net>
3673 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3674 * NEWS: Start news for current version.
3676 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3678 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3679 Define HAVE_GETMNTENT to 1, not to the empty string.
3680 Problem originally reported by Jochen Friedrich in
3681 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3683 This change prompted by a problem report by Andrey Simonenko in
3684 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3685 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3686 object-like macros only, in the traditional portable character
3687 set.
3688 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3689 Warn about attempts to define things that are not identifiers.
3690 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3691 awful hack that AC_DEFINEd macro names containing parentheses.
3693 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3695 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3696 too drastic, even if Texinfo in theory requires it for info mode.
3698 (config.status Invocation): Renamed back from Recreating a
3699 Configuration).
3700 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3701 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3703 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3705 * NEWS: Version 2.61a.
3707 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3708 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3710 * NEWS: Document changes with echo and printf, and the lack
3711 of limits on the total size of multi-line values of substituted
3712 variables, and the AC_FUNC_FSEEKO fix.
3714 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3716 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3717 Writing configure.ac.
3718 (Autoconf Input Layout): Renamed from configure.ac Layout.
3719 (Recreating a Configuration): Renamed from config.status Invocation.
3720 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3721 (acconfig Header): Renamed from acconfig.h.
3722 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3723 (Writing Testsuites): Renamed from Writing testsuite.at.
3724 (Autom4te Cache): Renamed from autom4te.cache.
3726 * BUGS: Remove mention of VPATH problem, since it's now documented
3727 not to be a bug in the Autoconf build procedure itself, but rather
3728 a problem with the proprietary `make' programs.
3730 * doc/autoconf.texi (Build Directories): Add a cross reference
3731 to VPATH and Make.
3733 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3734 * doc/standards.texi: Sync from gnulib.
3736 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3737 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3738 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3739 generated automatically.
3741 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3743 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3744 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3745 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3747 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3749 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3750 `CEOF$ac_eof' special marker, the awk script cannot contain a
3751 line matching `^CEOF', so this is not needed any more.
3752 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3753 special marker in the test.
3755 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3757 * tests/tools.at (autom4te preselections): Use `find -newer';
3758 remove one of the sleeps.
3760 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3761 more readable, using ...
3762 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3764 * doc/autoconf.texi (autoheader Invocation): Do not double-
3765 quote the parameter of `AH_BOTTOM' in the example.
3767 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3769 * doc/autoconf.texi (Configuration Headers): Remove the
3770 example with multiple input files.
3771 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3772 multiple input files.
3774 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3776 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3777 creating the awk substitution script, handle one input line at a
3778 time, so that the maximum length of a substituted (multi-line)
3779 value is not limited by the size of the sed pattern space.
3780 The trade-off is a slightly repetitive sed script.
3781 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3782 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3783 * tests/torture.at (Substitute a 2000-byte string): Increase the
3784 test with several long lines, they should not be caught by sed
3785 limits any more.
3787 * tests/tools.at (autom4te preselections): New test, to flag
3788 entries missing from autom4te.cfg.
3789 Report by David Byron <dbyron@hheld.com>.
3791 * tests/torture.at (Substitute a 2000-byte string): Actually use
3792 AC_PROG_AWK, so the last change works as intended.
3793 (Substitute and define special characters): Likewise.
3794 (Substitute a newline): Likewise.
3796 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3797 instead of `awk' consistently.
3798 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3799 * tests/torture.at (Torturing config.status): Test both the
3800 result of AC_PROG_AWK and plain awk.
3801 (Substitute a 2000-byte string): Likewise.
3802 (Substitute and define special characters): Likewise.
3803 (Substitute a newline): Likewise.
3805 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3807 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3808 can be assigned to a function pointer. Problem reported by
3809 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3810 part of a patch by Ralf Wildenhues in that same bug report.
3812 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3814 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3815 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3817 2006-12-01 Eric Blake <ebb9@byu.net>
3819 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3820 cross-compiling from cygwin to mingw.
3821 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3822 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3823 to lib/autoconf/c.m4.
3825 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3827 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3828 string for more reliable failure. Wrap the entire test that
3829 causes the broken Solaris printf to dump core, in a subshell,
3830 so the segmentation fault message is reliably suppressed.
3831 Fix shell expansion errors by using /usr/ucb/echo always;
3832 avoid an error on systems without it by another subshell.
3833 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3834 subshell-$as_echo to `as_echo', for better error message.
3836 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3838 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3839 `BASH_SOURCE' contain a newline, set them to empty, as they may
3840 not be unset.
3842 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3844 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3845 years and is too hard to maintain now. The last straw was
3846 reported by Jerker Baeck in
3847 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3848 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3849 * doc/autoconf.texi (Particular Functions): Move
3850 AC_FUNC_SETVBUF_REVERSED from here...
3851 (Obsolete Macros): ... to here. Say that it does nothing now.
3852 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3853 Turn into (almost) a no-op.
3855 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3856 (AC_C_VOLATILE):
3857 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3858 These macros are obsolescent and new applications shouldn't need them.
3859 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3860 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3861 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3862 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3863 (AC_FUNC_VPRINTF): Likewise.
3864 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3865 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3866 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3868 * doc/autoconf.texi (Setting Output Variables): Mention that
3869 @VAR1@VAR2 has unspecified behavior. Problem reported by
3870 Ralf Wildenhues.
3871 * NEWS: Mention this.
3873 * Makefile.am: Put only a single '#' into the copyright notice,
3874 so that it's also present in the output file. Standardize wording
3875 in makefile copyright notices to match GNU coding standards.
3876 * bin/Makefile.am: Likewise.
3877 * doc/Makefile.am: Likewise.
3878 * lib/Makefile.am: Likewise.
3879 * lib/freeze.mk: Likewise.
3880 * lib/autoconf/Makefile.am: Likewise.

3884 * man/Makefile.am: Likewise.
3885 * tests/Makefile.am: Likewise.
3886 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
3887 one-line file.
3889 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3891 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3892 in the sed script that mangles the awk script: delete up to the
3893 first exclamation mark only.
3894 * tests/torture.at (Substitute and define special characters):
3895 Test '!' too.
3897 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3899 Rewrite config files generation: avoid quadratic growth in
3900 the number of substituted variables by using awk instead of sed
3901 for the bulk of the substitutions.
3902 * NEWS: Mention this.
3903 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3904 forbidden in the output (and thus input) file.
3905 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3906 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3907 generate just one large awk script for substitutions,
3908 eliminating much of the earlier complexity, while adding some
3909 new complexity. Only expand the substitution templates at
3910 configure time, for smaller configure script size. If
3911 _AC_SUBST_FILES are used, test 'awk' for working getline support
3912 at config.status time. If absent, interpolate through the
3913 shell. The awk script was written with much help
3914 from Paolo Bonzini and Paul Eggert.
3915 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3916 (_AC_SED_FRAG_NUM): Likewise.
3917 (_AC_SUBST_CMDS): Renamed from...
3918 (_AC_SED_CMDS): ...this.
3919 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3920 * tests/torture.at (Substitute a 2000-byte string): Also
3921 substitute a line with 1000 words, and a variable with several
3922 long lines.
3923 (Substitute and define special characters): Test awk special
3924 characters, and put substitution input strings `@foo@' in the
3925 output, to test that no recursion happens; test several other
3926 combinations from Paolo Bonzini.
3928 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3930 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3931 that replaced echo with AS_ECHO where this wasn't necessary.
3932 Problem reportd by Ralf Wildenhues.
3933 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3934 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3935 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3937 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3939 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3941 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3943 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3944 that traditional Awk lacks 3-arg "split". It has it.
3945 Mention that FS must be a single character, and a few other
3946 99-byte limits of traditional Awk.
3947 Mention that if (i in a) doesn't work with traditional Awk.
3949 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3951 * tests/autotest.at (BSx641-newline in command):
3952 (BS-BS-newline in command, BSx640-newline in command):
3953 (Newline-CODE-BS-newline in command):
3954 (Single-quote-BS-newline in command):
3955 (Single-quote-newline-BS-newline in command):
3956 Use printf '%s\n' instead of echo, for portability to hosts
3957 where echo interprets backslashes. This will break on hosts
3958 that lack printf, but for now let's assume all such hosts
3959 are dead (if not, we should get reports of test failures).
3961 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3963 'echo' has some portability problems, when given a first argument
3964 with a leading '-', or when given any argument containing '\'.
3965 Avoid using 'echo' in these cases.
3966 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
3967 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
3968 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3969 * lib/autotest/general.m4 (AT_INIT): Likewise.
3970 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
3971 argument might be unportable.

3973 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

3990 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3991 * bin/autoconf.as: Redo verbose flag implementation, as the old
3992 scheme wouldn't work with AS_ECHO.
3993 * lib/autotest/general.m4 (AT_INIT): Likewise.
3994 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3995 Don't use ECHO_T, since ECHO_N is now reliable.
3996 * lib/autotest/general.m4 (AT_INIT): Likewise.
3997 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3998 rather than using a here-document to put the script into a file.
3999 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
4000 use AS_ECHO.
4001 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
4002 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
4003 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
4004 bug, but we might as well stop using ECHO_N and ECHO_C internally.
4005 * lib/autotest/general.m4 (AT_SETUP): Likewise.
4006 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
4007 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4008 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
4009 operand, as AS_ECHO requires. Avoid double file name expansion.
4010 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
4011 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
4012 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
4013 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
4014 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
4015 Double-quote strings that would otherwise contain M4 comments.
4016 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
4018 * configure.ac (AC_INIT): Bump to 2.61a.
4019 * NEWS: Likewise.
4021 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4023 Version 2.61.
4025 * configure.ac (AC_INIT): Bump to 2.61.
4026 * NEWS: Likewise.
4028 * tests/autotest.at (Macro with backslash in a test title):
4029 Comment out for now, as this tests neither fails nor passes
4030 reliably. Problem reported by Ralf Wildenhues.
4032 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4034 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
4035 in previous change, which caused test failures.
4037 2006-11-16 Stepan Kasal <kasal@ucw.cz>
4039 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
4040 code for --enable, --disable, --with, and --without to...
4041 (_AC_INIT_PARSE_ENABLE): ... a new macro.
4042 * doc/autoconf.texi (Package Options):
4043 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
4045 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4047 Import these changes from config via gnulib:
4049 2006-11-15 Ben Elliston <bje@gnu.org>
4051 From Josselin Mouette <joss@debian.org>:

4106 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
4108 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
4109 benefit of platforms like Solaris+GCC where it is common to have a
4110 non-working g++ installation.
4112 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4113 and Joel E. Denny <jdenny@ces.clemson.edu>
4114 and Paul Eggert <eggert@cs.ucla.edu>
4116 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
4117 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
4118 ./micro-suite.
4120 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4122 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4123 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4124 Imported from a similar patch to gnulib by Bruno Haible.
4126 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4128 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

4136 Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
4137 Matthew Woehlke.
4139 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4141 * tests/torture.at (Configuring subdirectories): Do not skip
4142 Automake 1.10 nor future Automake 11.1 (sic).
4144 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
4145 and Stepan Kasal <kasal@ucw.cz>
4147 Handle special characters in test case titles correctly.
4148 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
4149 properly.
4150 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4151 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
4152 argument. Extend to check titles printed by ./micro-suite and
4153 ./micro-suite -l and the title in micro-suite.log.
4154 (Backquote in a test title,
4155 Single-quote in a test title,
4156 Double-quote in a test title): Don't expect failure anymore.
4157 (Backslash in a test title): Put a non-whitespace character after the
4158 backslash so that Bourne shells might actually see it as an escape
4159 sequence.
4160 (Brackets in a test title,
4161 Pound in a test title,
4162 Comma in a test title,
4163 Quoted Macro in a test title,
4164 Macro in a test title,

4169 * tests/torture.at (#define header templates): M4-quote this title in
4170 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4171 The visible effect was a stray [] in the testsuite output.
4173 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4175 * doc/autoconf.texi (Limitations of Builtins): Do not invoke

4178 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4180 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4181 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4182 5363) simply issues a warning when dividing by zero at compile
4183 time. Problem reported by Elias Pipping.
4185 2006-10-26 Eric Blake <ebb9@byu.net>
4187 * THANKS: Update.
4188 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4189 show effect on macros that expand with commas.

4193 Also work with M4 1.4.8.
4195 2006-10-25 Paul Eggert <eggert@cs.ucla.edu>
4197 * doc/autoconf.texi (Slashes): Document Tru64 4.0 bug reported by
4198 Jim Meyering.

4203 `--force' always rewrites the output file.
4205 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4207 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm

4216 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4217 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4218 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4219 reported by Nelson H. F. Beebe for Coreutils 6.4.
4221 * tests/tools.at (autoconf --trace: user macros): Remove test
4222 for tracing multiline macros, since m4 1.4.7a uses a different
4223 way to number lines. Problem reported by Ralf Wildenhues.
4225 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4227 * bin/autom4te.in (handle_m4): Do not redirect stdin to
4228 /dev/null since the heuristics for interactive behaviour was
4229 fixed in CVS m4.
4231 * bin/autom4te.in: With --force, always refresh the output
4232 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
4234 * bin/autoconf.as: Fix the verbose message at the end.
4236 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

4285 looking for special shell characters.
4286 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4287 macro defined by AS_VAR_PUSHDEF before passing it as a
4288 parameter.

4301 (Imported from Automake.)
4302 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4303 which incorrectly sets the mode of an existing destination
4304 directory. In some cases the unpatched install-sh could do the
4305 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4306 system. We hope this is rare in practice, but it's clearly worth
4307 fixing. Problem reported by Alex Unleashed in
4308 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4309 Also, don't bother to check for -m bugs unless we're using -m;
4310 suggested by Stepan Kasal.
4312 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4314 Import this change from Automake:
4316 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

4319 Report from Bruno Haible.
4321 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

4332 2006-09-16 Karl Berry <karl@gnu.org>
4333 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4334 to avoid sectioning errors.

4339 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
4340 (\quoteexpand): rename to \rquoteexpand.
4341 (\codequoteleft): new def, to look for @set codequotebacktick.
4342 (\lquoteexpand, \quoteexpand): new defs.
4343 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.

4361 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4363 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4364 include the default headers, and redefine obstack_chunk_alloc
4365 and obstack_chunk_free. Fixes false failure with glibc.
4367 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4369 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

4386 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4387 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4388 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4389 Use a better substitute, by inspecting the output of "ls"
4390 rather than just using ":".
4391 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4392 rather than AS_EXECUTABLE_P, since we needn't worry about
4393 non-regular files here.
4395 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4396 due to configuration hassles with this. See Tonya Underwood's report

4406 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4408 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4409 initialization which is not inherited through the environment
4410 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4411 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

4418 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4420 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4421 comment about ac_cpp_err; it was incorrect, and anyway
4422 ac_cpp_err is being removed below.
4423 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4424 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4425 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4426 nobody uses it.
4427 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4428 with werror_flag and conftest.err and so forth. This is more
4429 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4430 and anyway the user shouldn't normally want to see this gorp logged.
4431 Problem reported by Ralf Wildenhues.
4432 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4433 empty, not 'no', since the rest of the code uses 'test -z'.
4435 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4437 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4438 Use a single call to AC_DO_TOKENS rather than multiple, for
4439 efficiency.
4440 (_AC_LINK_IFELSE): Test that resulting file is executable.
4441 Problem reported by mwoehlke in
4442 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4444 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4445 than creating a file to use with test -x; this is much faster.
4447 2006-10-02 Bruno Haible <bruno@clisp.org>
4449 * lib/autom4te.in (Automake-preselections): Add
4450 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4452 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4454 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4455 standard error, `experr' should be used, not `expout'.
4457 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4459 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4460 fseeko testing program twice; just use the earlier result.
4461 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4462 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4463 still doesn't let the program compile.
4464 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4465 failed.
4467 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4468 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4469 include it, without including anything else.
4470 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4471 expressions.
4472 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4474 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4476 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4477 `error.h', and include it, for a `error_at_line' prototype.
4478 Use a nonempty format string in the link test.
4479 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4480 for a declaration of wait3.
4482 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4484 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
4485 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4486 can apply to constants too, and that it checks for macro defns.
4487 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4488 and simply cast the identifier to void. This handles structure
4489 values. Problem reported by Ralf Wildenhues.
4490 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
4492 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4578 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
4579 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
4580 for the existence of the directory at configure-time. That's
4581 too late, anyway. Problem reported by Stefan Seefeld.
4583 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
4584 7.1.4 /usr/bin/posix/sh described by Tim Rice in
4585 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
4587 2006-09-11 Stepan Kasal <kasal@ucw.cz>
4589 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
4590 works with GNU M4 1.4.3 again; make the normalized form
4591 match the current m4 message; fix the description.
4592 * test/tools.at (autom4te cache): Adapt to the change.
4594 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
4596 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
4597 to catch glibc bug 2821
4598 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
4600 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
4601 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
4602 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
4603 assume C89.
4605 2006-09-08 Stepan Kasal <kasal@ucw.cz>

4623 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4625 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
4626 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
4627 accept files with extension `.f'. For consistency, also prefer
4628 xlf over f77.
4629 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
4630 from last patch.

4651 except the first two arguments are reversed.
4652 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
4653 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
4654 caches nor outputs a diagnostic. Suggested by Bruno Haible.
4655 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
4656 equivalent to the old AC_COMPUTE_INT.
4657 (AC_COMPUTE_INT): No longer caches or reports. New signature.
4658 All uses changed to AC_CACHE_CHECK_INT.
4659 * tests/base.at (AC_CACHE_CHECK_INT): New test.
4660 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
4662 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
4664 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
4665 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
4666 programs should use their Gnulib counterparts.
4667 * doc/autoconf.texi (Particular Functions): Likewise.

4669 obsolete macros with uses of non-obsolete macros.

4697 Fix Lex library problem reported to us by Julio Garvia.
4698 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
4699 for the default, which the user can override.
4700 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
4701 deal with LEXLIB.
4702 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
4703 didn't work if some values were cached but not others. Test for
4704 broken lex libraries like native ia64-hp-hpux11.22; see
4705 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4706 work around the problem by preferring an empty LEXLIB to -lfl or
4707 -ll. Let the user set LEXLIB='' to indicate no library needed.

4812 * doc/autoconf.texi (Particular Programs): Mention that
4813 @INSTALL@ and @MKDIR_P@ may vary for different output files.

4819 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
4820 Bill Northcott in
4821 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.

4833 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
4834 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
4835 -Wundef -Werror". Problem reported by David Fang in
4836 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
4837 * doc/autoconf.texi (Header Templates, Default Includes):

4852 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
4853 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
4854 this.

4858 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
4859 problems with arg script text that doesn't end in newline, and
4860 with '-e a...'. Problems reported by Ralf Wildenhues.
4862 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
4864 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
4865 check for libXt by a check for libX11.
4867 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4870 to last change.
4872 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4874 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
4875 --help' should mention that `--version' outputs configuration
4876 settings. Report by Bruno Haible.
4878 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
4880 Fix test suite failures reported by Pierre in
4881 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
4882 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
4883 the compiler created a file "b.out" when it didn't create anything
4884 at all.

4886 Discard stderr too, when invoking the test script.
4888 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
4890 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
4891 in the restoring of the werror flag.
4893 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
4895 * doc/autoconf.texi (Volatile Objects): Be even a little
4896 less skeptical about "volatile", after discussion with
4897 Bruno Haible on bug-gnulib.
4898 (Limitations of Usual Tools): Warn about sed stripping
4899 leading white space from text. From Bruno Haible.
4901 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4903 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
4904 compiler complains about it, even if things works after the
4905 complaint. Problem reported by Peter O'Gorman.
4907 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
4908 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
4909 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
4911 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
4913 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

4923 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4925 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
4926 under AC_C_VOLATILE.
4927 (Volatile Objects): Be a little less skeptical about what
4928 "volatile" means. Derived from thoughts by Ben Pfaff in
4929 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
4931 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4933 * doc/autoconf.texi: Fix some typos.
4935 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4937 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4938 more globally, since the 2006-06-30 patch didn't suffice. Problem
4939 reported by Keith Marshall. Also, don't bother with builddir2,
4940 since it shouldn't be needed any more.
4942 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
4944 * doc/autoconf.texi (Generic compiler characteristics):
4945 Document AC_COMPUTE_INT. Fix wrong statements on Default
4946 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.

4959 * NEWS: Document previous change.
4961 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4963 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4964 Require that long long int be at least 64 bits wide. C99 requires
4965 this and enough programs depend on it so we should check for it.
4966 Bruno Haible reports in
4967 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4968 that long long int is 32 bits wide with some nonstandard compilers.
4969 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
4971 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4973 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4974 to a nonexistent file, so that we don't have to worry about
4975 a local site configuration that doesn't use /usr/local.
4976 Problem reported by Keith Marshall in
4977 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4979 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4981 * doc/autoconf.texi: Be more consistent about using @acronym with
4982 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4983 quite right (it talked about "OSF/Tru64", even though the
4984 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4985 and it even mentioned "OSF 4"!) and at this point there's little
4986 reason to talk about OSF any more, since it died in 1994.
4987 (Specific Compiler Characteristics): Simplify example of
4988 negative-size array.
4989 (File Descriptors): Reorder to make the text flow better.
4990 Remove joke about "appreciate the various levels"; I didn't get it.
4991 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4992 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4993 (File Descriptors, Limitations of Usual Tools):
4994 Tone down the advice against renaming or removing open files.
4995 (Limitations of Usual Tools): Add a new section, on 'rm'.
4997 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4999 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5000 -lXt in LIBS, idea from Karsten Hopp; this was due since
5001 this change:
5003 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5004 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5005 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5006 (which belong to Xt, not X itself). See Debian bug 327655.
5008 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5010 * configure.ac (AC_INIT): Bump to 2.60a.

5019 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5021 * config/texinfo.tex: Sync from upstream.
5023 * bin/autom4te.in (handle_traces): Transform the `@S|@'
5024 quadrigraph correctly in traces.
5026 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
5027 Fix typos.
5029 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
5030 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5031 not defined.
5032 * doc/autoconf.texi (Changed Directory Variables): New node,
5033 to document the whole `datarootdir' business a bit better.
5034 * NEWS: Update.
5035 * tests/torture.at (datarootdir workaround): Extend test.
5036 Prompted by report by Alexandre Julliard.
5038 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5040 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility

5042 fix reported by Larry Jones.
5044 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5046 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5047 about literal '${datarootdir}' if a definition is found in the
5048 output file.
5050 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5052 * NEWS: Use "M4" rather than "m4" when appropriate.
5053 Problem reported by Eric Blake.
5054 * doc/autoconf.texi: Likewise.
5055 Use @acronym around BSD, GCC, and GNU when appropriate.
5056 (Why GNU M4): Renamed from "Why GNU m4".
5057 (Redefined M4 Macros): Mention that Posix
5058 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5059 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5060 to int.
5062 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5064 * bin/autom4te.in (handle_output): Do not forbid the empty
5065 pattern.
5066 * tests/tools.at (autoconf: the empty token): New test.
5068 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5070 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5071 calls, so that we do not care whether they are LIFO or FIFO;
5072 in the m4_wrap, do not check which diversion is the topmost
5073 one, just check that the stack is balanced at the end.
5074 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5075 base diversion forever--pop the previous diversion before
5076 opening the new one; consequently, remove the m4_wrap call.
5077 * lib/autotest/general.m4 (AT_INIT): Likewise.
5078 * tests/m4sugar.at: Do not use
5079 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5081 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5082 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5084 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5085 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5086 Rework example of m4wrap token-pasting trouble so that it doesn't
5087 care whether it's LIFO or FIFO.
5088 Fix some "contrary to"s that are awkward in English.
5090 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5092 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5093 to `yes' instead of `int$1_t' if the type is found, for more
5094 consistent configure output (where $1 is the number of bits).
5095 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5096 Suggested by Bruno Haible.
5098 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5099 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5100 with system headers. Report by Bruno Haible.
5102 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5104 * config/config.guess, config/config.sub: Sync from upstream.
5106 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5107 in order to avoid picking up an older installed frozen m4sh.m4f.
5108 Besides an outdated shell startup, this could have been created
5109 by an earlier M4 version with incompatible frozen file format.
5111 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5113 * README: Recommend m4 1.4.4 instead of 1.4.3..
5114 * doc/autoconf.texi: Likewise.
5115 (Special Chars in Names): Say that $(.FOO) is portable, as
5116 suggested by Stepan Kasal.
5117 (Installation Directory Variables, Build Directories):
5118 (Automatic Remaking, Subdirectories, Fortran Compiler):
5119 (Making testsuite Scripts, Defining Directories):
5120 Quote variable usages better.
5121 (Making testsuite Scripts): Add clean-local rule to makefile
5122 snippet, by Eric Blake.
5123 (Installation Directory Variables): Fix table item font.
5124 Reword slightly to clarify. Generalize advice about
5125 not using special characters to include all file-related
5126 vars, not just VPATH.
5127 (Special Chars in Variables): Warn about special characters in
5128 $(srcdir) too.
5129 (Assignments): Clarify default-value example as suggested by
5130 Ralf Wildenhues in
5131 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5132 (Special Shell Variables): Note leading ./ or ../, as suggested
5133 by Eric Blake.
5134 (Limitations of Builtins): Under cd, warn about CDPATH.
5135 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5136 Ralf Wildenhues.
5138 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5140 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5141 `@var', for texi2html.
5142 (Systemology): Some more word wrapping, for DVI output.
5143 (autom4te Invocation): The short option for `--melt' is `-M',
5144 not `-m'.
5146 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5148 * doc/autoconf.texi: More formatting and English tweaks,
5149 many suggested by Ralf Wildenhues.
5150 Reword to avoid "@code{...}'s" and the like, since it's ugly
5151 with Emacs info mode. discontents -> woes.
5152 Put a few "will"s back. time stamp -> timestamp.
5153 side-effect -> side effect.
5155 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5157 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5158 Warn about $@ not persisting. Problem reported by Julien Danjou in
5159 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5160 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5161 Mention other special chars, too.
5163 2006-06-14 Eric Blake <ebb9@byu.net>
5165 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5167 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5169 * doc/autoconf.texi: Some systematic minor improvements, as
5170 follows. Use "makefile" when talking about makefiles
5171 generally (which might be named "makefile" or "Makefile" or even
5172 "foo.mk"), "Makefile" when talking about a specific makefile
5173 called "Makefile". This unclutters the text from weird quotes
5174 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5175 values" rather than "@var{foo}s" and similar constructs containing
5176 "}s". Use "Make rules" rather than "Makefile rules". Minor
5177 English-language improvements. Change the prefix "sub-" to "sub"
5178 and "re-" to "re".
5179 Put blank lines around examples more consistently.
5180 Avoid "rather" and "very" as intensifiers.
5181 Avoid "will" as an auxiliary.
5182 (Limitations of Make): Split this node into....
5183 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5184 (Leading _ in Macro Names, Backslash-Newline-Newline):
5185 (Backslash-Newline Comments, Long Lines in Makefiles):
5186 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5187 (obj/ and Make, make -k Status, VPATH and Make):
5188 (VPATH and Double-colon, $< in Explicit Rules):
5189 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5190 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5191 New nodes, resulting from splitup of Limitations of Make.
5192 All cross-references changed. Raise the top node from
5193 a section to a chapter, and all subnodes accordingly.
5194 Redo the introductory wording to match the new organization.
5195 (Installation Directory Variables): Use an example that is
5196 closer to what Autoconf actually does. Mention that VPATH's
5197 value should not contain metacharacters or white space.
5198 (Fortran Compiler): Fix a VPATH bug in an example.
5199 (Leading _ in Macro Names): Mention that this problem is no longer
5200 of practical concern.
5201 (VPATH and Make): Reword the advice to make it clearer
5202 that Autoconf and Automake support VPATH in non-GNU make, but
5203 many packages have bugs in this area.
5204 ($< in Explicit Rules): Refer to Build Directories rather
5205 than using a (non-VPATH-safe) example.
5206 (Automatic Rule Rewriting): Mention the sort of disaster that
5207 can ensue with Solaris-style rule rewriting with VPATH.
5209 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5211 * doc/install.texi (Compilers and Options): Weaken the
5212 suggestion to use GNU make for VPATH builds.
5214 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5215 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5217 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5218 in regular expression.
5220 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5222 * doc/autoconf.texi (Installation Directory Variables):
5223 Drop extra @samp from `@table @samp' item.
5224 (Limitations of Usual Tools): Comment fix.
5225 Do not nest @samp just to point to other table items.
5226 (Writing testsuite.at) <AT_CHECK>: The second argument to
5227 `@dvar' is already @samp'ed.
5228 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5229 do not use @var in the second argument.
5231 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5233 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5234 $as_shell.exe too. Problem reported by Andreas Buening in
5235 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5237 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5239 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5240 `unused variable' compiler warning, for `-Wall -Werror'.
5241 Reported by Jaap Haitsma in
5242 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5244 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5246 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5247 case the compiler dumps core. Problem reported for
5248 OpenServer 5.0.7 by Tim Rice in
5249 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5250 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5251 Likewise.
5253 2006-06-06 Tim Rice <tim@multitalents.net>.
5255 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5256 "ERROR" only shows up in "make check" output if there is an
5257 error.
5259 2006-06-06 Eric Blake <ebb9@byu.net>
5261 * tests/tools.at (automatically allowed tokens): Fix typo.
5263 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5265 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5267 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5268 typically overflows on x86 CPUs, even though the C standard
5269 requires otherwise.
5271 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5273 * configure.ac (AC_INIT): Bump to 2.59e.
5274 * NEWS: Update.
5276 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5278 Version 2.59d.
5280 * config/texinfo.tex: Sync from upstream.
5282 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5283 seen, invoke libtoolize with `--ltdl' argument.
5284 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5285 * NEWS: Update.
5286 Suggested by Eric Blake.
5288 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5290 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5291 reported by Ralf Wildenhues.
5292 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
5294 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5296 * THANKS: Update.
5298 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5300 * doc/autoconf.texi: Modernize some of the references to Solaris.
5302 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5304 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5305 message issued by AC_REQUIRE.
5306 * tests/m4sugar.at: Check m4_require's error message.
5307 * tests/base.at: Check AC_REQUIRE's error message.
5308 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5309 to...
5310 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5311 AT_CHECK_M4.
5312 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5313 `expout' as the last parameter.
5314 * tests/tools.at: Adapt to the above change.
5316 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5318 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5319 information about race-free implementations of mkdir.
5321 2006-06-04 Eric Blake <ebb9@byu.net>

5324 * bin/autoconf.as (Usage): Likewise.
5325 * bin/autom4te.in (help): Likewise.
5326 * doc/autoconf.texi (autom4te Invocation): Likewise.
5328 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5330 * NEWS: GNU make now recommended for VPATH builds.
5331 Mention that some macros are now documented to be obsolescent.
5332 * doc/autoconf.texi:
5333 Prefer "current" to "modern" to describe
5334 currently-used (albeit perhaps old-fashioned) hosts.
5335 Mention which ancient features no longer need to be worried about.
5336 setgid -> set-group-ID
5337 setuid -> set-user-ID (these are the Posix terms)
5338 Fix some misuses of "only".
5339 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5340 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5341 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5342 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
5343 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
5344 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
5345 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
5346 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
5347 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
5348 Mention that these macros are obsolescent.
5349 (Installation Directory Variables): shall -> should
5350 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5351 Mention that it's now safe to use 3 and 4.
5352 (Limitations of Usual Tools): cp -r is now specified by Posix.
5353 Omit longwinded and obsolescent discussion of cp -f.
5354 Modernize discussion of expr, ls.
5355 (Limitations of Make): Modernize discussion of VPATH builds.
5356 Mention $? as a workaround in some cases.
5357 * doc/install.texi (Basic Installation):
5358 Mention "./configure; make; make install" first. Be more
5359 specific about why this file is generic. Remove unnecessary
5360 parens. Remove misleading "only". Remove obsolete advice
5361 about csh. Don't say "configure" takes awhile; say it
5362 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5363 and CC=c99 rather than CC=c89, as these are blessed by current
5364 Posix. Recommend GNU make if doing a VPATH build.
5366 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5368 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5369 examples involving shell prompts.
5371 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5372 and Paul Eggert <eggert@cs.ucla.edu>
5374 * doc/autoconf.texi (Here-Documents): Add details about the
5375 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5376 use "here-documents" instead of "here documents".
5378 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5380 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5382 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5384 * doc/autoconf.texi (File System Conventions): Warn about ":"
5385 anywhere in directory names.
5387 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5389 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5390 about quoting the case statement, just in case.
5391 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5392 was fixed in ksh93g; reported by Ralf Wildenhues.
5394 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5396 * doc/autoconf.texi (System Services): Do not document
5397 overriding EXEEXT via ac_cv_exeext=ext.
5398 (Particular Programs) <AC_PROG_MKDIR_P>:
5399 Document that ${MKDIR_P} understands --.
5400 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5401 comment.
5403 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5405 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5406 argument with leading hyphen. Problem reported by Paul Eggert.
5408 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5410 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5411 about quoting ac_try: quote all of it, if any of it seems suspicious.
5412 This means we don't have to worry about ${ or sed any more.
5413 Also, double-quote the case statement, to work around misuses via
5414 underquoting as reported by Ralf Wildenhues in
5415 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5416 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5417 undocumented and dangerous macro.
5418 Problem reported by Ralf Wildenhues in
5419 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5421 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5423 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5424 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5425 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5427 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5429 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5430 since evidently some packages rely on the old, broken behavior.
5431 Problem reported by Ralf Wildenhues in
5432 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5433 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5434 pre-2006-05-26 definitions, but leave in the comments that
5435 these macros are dangerous and should not be used.
5436 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5437 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5438 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5439 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5440 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5442 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5444 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5445 the use of 'tr', since this is our only use of 'tr'.
5447 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5448 and Paul Eggert <eggert@cs.ucla.edu>
5450 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5451 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5453 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5455 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5456 the output file in the `${datarootdir}' test.
5458 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5459 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5461 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5462 mention of `datarootdir' in the input file(s), but literal
5463 `${datarootdir}' in the output file, and we haven't warned yet,
5464 then warn as well: the user may have (erroneously) used
5465 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5466 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5467 * tests/torture.at (datarootdir workaround): Extend this test.
5468 * NEWS: Update.
5470 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5471 and Paul Eggert <eggert@cs.ucla.edu>
5473 * doc/autoconf.texi (autoheader Invocation): The first argument to
5474 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5475 alternatives and clear up the language a bit.
5477 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5479 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5480 ac_config_guess, ac_config_sub, ac_configure.
5481 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5482 Fix typo that prevented an unnecessary space from being removed.
5483 Problems reported by Ralf Wildenhues in:
5484 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5486 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5488 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5489 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5490 Don't use the term "thread-safe" to talk about mkdir race
5491 conditions, since the problem is more a process than a thread
5492 issue. Problem reported by Stepan Kasal in:
5493 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5494 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5495 the test for 'install' more closely. Look at MKDIR_P first.
5496 Look in the PATH, and at /opt/sfw/bin.
5497 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5498 Don't bother to try mkdir -p, since we already check mkdir --version;
5499 just look at the version number. (There's no easy way to check
5500 for race-free implementations.)
5501 * tests/tools.at (autoconf: subdirectories): Adjust to above
5502 changes, since MKDIR_P now might end in "/mkdir -p".
5504 * doc/autoconf.texi (autoheader Invocation): Mention that the
5505 first arg of AC_DEFINE_UNQUOTED must be a literal.
5506 Problem reported by Ben Pfaff in
5507 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5509 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5510 * doc/autoconf.texi (Special Chars in Variables): New section.
5511 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5512 (Installation Directory Variables): Quote $(datadir) better.
5513 (Limitations of Builtins): Describe some of eval's trickiness.
5515 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5516 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5517 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5518 in front of every arg, not just trailing args. Quote apostrophes.
5519 (_AC_EVAL_ECHO): New macro.
5520 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5521 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5522 removed.
5523 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5524 exposed by quoting of eval argument. Put the command on line line
5525 so it logs better.
5526 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5527 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5528 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5529 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5530 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5531 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5532 Use eval more safely.
5533 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5534 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5535 to be replaced.
5536 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5537 lines, exposed by quoting of eval argument.
5539 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5540 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5542 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5543 initialization of `ac_cv_exeext', do not override it if it was
5544 already set, unless it was set to `no', for compatibility with
5545 Autoconf-2.13, and comment this.
5546 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5547 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5548 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5549 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5550 Document that this test may be overridden by setting
5551 `ac_cv_exeext'.
5553 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5555 Revert these two patches:
5557 2006-04-06 Eric Blake <ebb9@byu.net>
5558 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5559 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5560 2006-04-01.
5562 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5563 Clean up _AC_COMPILER_EXEEXT* macros.
5564 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5565 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5566 ac_file to the name of the default output file and call
5567 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5568 initial `rm' of the candidate files...
5569 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5570 the same list in subsequent `rm' calls, and for the temporary
5571 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5572 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5573 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5574 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5575 no longer needed) by libtool. Make it a cache check.
5576 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5577 copied here by mistake.
5578 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5579 _AC_COMPILER_EXEEXT.
5580 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5581 _AC_COMPILER_OBJEXT directly.
5582 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5584 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5586 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5587 Fix description of how the buggy `sed' works.
5589 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5591 Sync from Automake:
5593 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5594 ENOLCK. Only mention `make -j' when applicable. Only raise
5595 fatal errors when `make -j' is involved. Improve error message.
5597 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5599 * doc/autoconf.texi (Here-Documents): We now know more about
5600 the variable expansion in here documents bug.
5601 Thanks to Tim Rice and Stepan Kasal.
5603 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5604 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5606 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5608 * tests/autotest.at (Multiline command from M4 expansion):
5609 No failure to be expected if the shell quotes newlines in
5610 commands in the `set -x' output. Report by Tim Rice.
5611 * THANKS: Update.
5613 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5615 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5616 expansion in the here-documents used by config.status, as that
5617 runs afoul of the Korn shell version M-12/28/93d bug described in
5618 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5619 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5620 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5622 2006-05-23 Jim Meyering <jim@meyering.net>
5624 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5625 Fix typo introduced with 2006-04-02 change. It reversed the sense
5626 of the test.
5628 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5630 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5631 ac_dB slightly, to save bytes in the script.
5632 Max out at 50 lines, rather than 96; this is more likely
5633 (though not guaranteed) to avoid obscure 'sed' failures.
5635 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5637 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5638 `tr -d -' as bad option argument. Work around this by deleting
5639 an unrelated character.
5640 Report by Tim Rice <tim@multitalents.net>.
5642 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5643 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5644 Stepan Kasal <kasal@ucw.cz>
5646 * doc/autoconf.texi (Particular Programs): Do not promise that
5647 we always prefer the GNU version of the program, and that we
5648 search according to PATH; both rules can have exceptions.
5649 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5650 AC_PROG_SED. Move descriptions of limitations
5651 to the Limitations of Usual Tools section.
5652 (Limitations of Usual Tools) <sed>: Mention script length
5653 limitations with Solaris /usr/ucb/sed.
5654 <grep>: Fix wording for empty alternative. Mention that -c and
5655 -l should not be combined, and that -E and -F should not be
5656 combined.
5658 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5659 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5661 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5662 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5664 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5666 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5667 AC_DEFINE is now passed to m4_pattern_allow.
5668 * NEWS: Mention that; likewise for AC_SUBST.
5669 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5670 the parameter to m4_pattern_allow.
5671 * tests/tools.at: Add a check for that.
5673 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5675 * lib/autoconf/status.m4: Fix typos.
5677 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5679 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5680 only the files that this macro generates.
5682 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5684 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5685 the HP-UX sed limitation of 99 commands, labels do not count.
5686 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5687 in the comment.
5688 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5690 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5692 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5693 Import the following fix from coreutils:
5695 2006-01-13 Jim Meyering <jim@meyering.net>
5697 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5698 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5699 not double-quote uses of that variable, to accommodate the rare
5700 case in which getmntent is available in none of the libraries
5701 checked. This happens at least on FreeBSD 5.0.
5703 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5705 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5706 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5707 some other programs unwisely rely on these undocumented vars.
5708 But put in warning comments about them.
5709 Problem reported by Ralf Wildenhues in
5710 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5711 * NEWS: Document that these variables are intended to go away.
5713 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5715 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5716 and set the language to C++ (analogous to the equivalent Fortran
5717 tests).
5719 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5720 * doc/autoconf.texi (C++ Compiler): Document it.
5721 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5722 * NEWS: Update.
5724 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5726 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5727 that caused config.status to generate 100-command sed scripts; the
5728 portable limit is 99.
5730 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5732 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5733 variable `ac_d' instead of `d' to avoid infringing namespace.
5734 Report by Ralf Menzel.
5736 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5738 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5739 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5740 * tests/tools.at (autoconf: subdirectories): New test, taken from
5741 the corresponding problem report by Ralf Wildenhues in:
5742 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5744 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5745 Quote some uses of shell variables if they might suffer unexpected
5746 globbing. This doesn't fix all instances of quoting problems that
5747 I found, just the easy ones that look safe.
5748 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5749 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5750 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5751 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5752 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5753 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5754 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5755 Likewise.
5756 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5757 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5759 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5761 * bin/autoreconf.in ($help): Reword according to the manual.
5762 Suggested by Olly Betts.
5764 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5765 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5767 * bin/autoreconf.in: Pass the directory argument to
5768 `require_configure_ac'. Fix comment.
5769 * tests/torture.at (Configuring subdirectories): Expose this.
5770 Reported by Olly Betts.
5772 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5774 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5775 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5776 Automake as follows:
5778 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5779 `$configure_in' instead of `configure.in', to preserve
5780 directory component.
5782 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5784 * config/config.guess, config/config.sub, config/texinfo.tex,
5785 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5787 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5789 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5790 test for C99 conformance; (bool) 0.5 is an integer constant
5791 expression, but (bool) -0.5 is not. Problem reported by Fedor
5792 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5794 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5796 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5797 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5798 Warn about obsolete install-sh files. Remove stray sentence
5799 fragment and fix cross reference.
5800 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5801 install -d; this undoes the 2006-05-10 change.
5802 (MKDIR_P): Mark with AN_MAKEVAR.
5803 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5804 that we don't require $INSTALL to be thread-safe. Move comments
5805 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5806 of AC_PROG_INSTALL. Output a message saying that we're checking
5807 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5808 MKDIR_P instead of AC_SUBST.
5809 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5810 Special magic for MKDIR_P, too.
5811 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5812 a dnl.
5813 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5815 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5817 Sync from Automake, as follows:
5819 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5820 * config/install-sh: Initialize IFS, so field splitting isn't
5821 turned off later.
5822 * config/mkinstalldirs: Likewise.
5823 * config/missing: Remove superfluous quotes. Replace all uses of
5824 `[' by `test', for consistency, and for..
5825 * config/missing (sed_minuso, sed_output): New variables.
5826 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5827 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5828 Fixes `missing' to detect `--output' for help2man. Fixes
5829 PR automake/483. Report by Dennis J. Linse.
5830 (autom4te): Document in `missing --help'.
5832 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5834 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5835 * config/install-sh: Don't use 'path' to talk about file names,
5836 as per GNU coding standards. Close a race condition reported by Ralf
5837 Wildenhues and Stepan Kasal. There is still a race condition
5838 on hosts that predate Posix 1003.1-1992, but we can't help this.
5839 Don't mishandle weird characters like space on pre-Posix hosts.
5840 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5841 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5842 AC_PROG_MKDIR_P from AS_MKDIR_P.
5843 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5844 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5845 earlier editions are not (including Automake 1.8.3).
5846 Do not suggest mkinstalldirs for thread-safety.
5847 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5848 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5849 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5850 presence of special characters and race conditions.
5851 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5852 in Autoconf's name space.
5854 2006-05-10 Bruno Haible <bruno@clisp.org>
5855 and Paul Eggert <eggert@cs.ucla.edu>
5857 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5858 from Automake with minor changes.
5859 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5861 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5863 * config/install-sh: Update to Automake CVS version, as follows:
5864 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5865 * lib/install-sh: Simplify the expr implementation of dirname.
5866 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5867 * lib/install-sh: Handle --, and diagnose unknown options.
5869 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5871 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5872 `./autom4te' to create `./testsuite', since the `all' target
5873 will ensure its presence, but `installcheck' should not create
5874 the uninstalled wrappers.
5876 * tests/torture.at (Unusual Automake input files): Skip if we
5877 detect automake < 1.8.
5879 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5881 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5882 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5883 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5884 * NEWS: Update.
5886 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5888 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5889 munge (multiple) white space and other oddities.
5890 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5891 single quotes in variable assignment.
5892 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5893 and similar failures by adding multiple spaces, tabs, and other
5894 special characters.
5895 Report and different test suggested by Francesco Romani
5896 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5898 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5899 single quotes, we only need to search for single quotes; this
5900 both simplifies the search pattern, and makes us less
5901 susceptible to `echo' variations for arguments not containing
5902 single quotes.
5903 (_AC_ARG_VAR_VALIDATE): Likewise.
5905 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5907 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5908 `$*' and IFS concatenation issue with traditional shells and
5909 bash-2.04. Report by Seanster@Seanster.com.
5911 2006-05-03 Bruno Haible <bruno@clisp.org>
5913 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5914 precisely which Mac OS X versions have the od problem.
5916 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5918 * doc/autoconf.texi: Use @option systematically.
5920 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5921 and Bruno Haible <bruno@clisp.org>
5923 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5924 about 'od'.
5925 (Integer Overflow): Mention the special case of integer division
5926 overflow.
5928 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5930 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5931 traditional shells like the Solaris one that do not use the
5932 first IFS character for assembling `$*'.
5933 Prompted by a related report from autoconf_bug@nro.ca.
5935 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5936 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5938 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5939 Mention more problems with the -e option.
5941 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5943 * NEWS: Typo.
5944 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5946 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5947 in URLs to improve DVI formatted output (requires texinfo 4.6).
5948 (System Services, Systemology, Shellology): Likewise.
5949 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5950 output.
5952 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5953 continuous text.
5954 (Runtime): Fix macro argument names to match description:
5955 `action-if-found' -> `action-if-true' and similarly.
5956 (Obsolete Macros): Likewise.
5957 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5958 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5959 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5961 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5963 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5965 * ChangeLog: Typo.
5966 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5967 DVI output.

5980 (Floating Point Portability, Exiting Portably): New sections.
5981 (Writing Test Programs): Fix some langauge. Recommend exiting
5982 with status 1, not merely nonzero. Clarify exit declaration.
5983 (Run Time): Move C exit status stuff to new Exiting Portably section.
5984 (Systemology): Mention Posix and levenez. Update v7 reference.
5985 (Portable Shell): Mention the Posix shell.
5987 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5989 * bin/autoconf.as (me): Replace by as_me.
5991 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5993 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5994 since as_me isn't set yet.
5996 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5998 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5999 a few minor bugs in this area.

6029 * lib/autoconf/headers.m4: Likewise.
6031 * doc/autoconf.texi (Run Time): Document the exit status situation
6032 with more accuracy and detail.
6034 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6036 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6037 Archive is not officially `GNU' any more. Update URL.
6038 (Defining Directories): Likewise
6039 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6041 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6043 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6044 newline from the `trap' code to finish `config.log'; the NetBSD
6045 /bin/sh resets the exit status after an empty command, as
6046 documented in doc/autoconf.texi.
6047 Reported by Dalibor Topic <robilad@kaffe.org>.
6049 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6051 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6052 Suggested by Bruno Haible.
6054 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6056 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6057 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6058 Instead, just list the shells that we know work.
6059 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6060 changed. Be more cautious about the _cv_ variable.
6061 * tests/tools.at (Syntax of the shell scripts): Check the
6062 _cv_ variable once, at first, to avoid an internal autoconf error
6063 when sh -n does not work.
6065 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6067 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6069 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6071 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6072 use ">&-" since we're only 99.999% sure that this is portable,
6073 and since the MinGW bug is fixed in a different way.
6074 * lib/autotest/general.m4 (AT_INIT): Likewise.
6076 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6078 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6079 before opening config.log, to avoid hitting a bug on MinGW.
6081 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6083 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6084 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6085 This works around a MinGW bug reported by Eric Paire.
6086 Make sure that all writes to the log file append to it,
6087 rather than possibly losing data.
6088 * lib/autotest/general.m4 (AT_INIT): Likewise.
6090 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6092 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6093 description.
6095 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6097 * NEWS: Update.
6099 * configure.ac (AC_INIT): Bump to 2.59d.
6101 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6103 Version 2.59c.
6105 * Makefile.maint (news-date-check): Do not require a leading `*'
6106 before the release date in NEWS.
6108 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6109 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6111 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6112 the instantiated file do not contain the string 'datarootdir'
6113 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6114 @mandir@, replace the reference '${datarootdir}' by the value.
6115 * tests/torture.at (datarootdir workaround): New test.
6116 * NEWS: Advertise this temporary fixup.
6117 Based on a patch by Bruno Haible, reported and analyzed by
6118 Paul Eggert and Noah Misch.
6120 2006-04-12 Eric Blake <ebb9@byu.net>
6122 * tests/autotest.at (Debugging a failed test): Fix comment.
6124 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6126 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6127 all the changes since 2006-04-07.
6129 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6131 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6132 succeeded, but `ln -s file dir' failed, take care to remove the
6133 leftover target before the next test, to prevent its spurious
6134 failure; also make sure `ln file dir' works before selecting it.
6135 Thanks to Keith Marshall for pointing this out.
6136 * THANKS: Update.
6138 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6139 assignments in `at_debug_args', so that we put them correctly
6140 in the `run' script.
6141 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6142 Reported by Eric Blake.
6144 2006-04-11 Eric Blake <ebb9@byu.net>
6146 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6147 top-level tests after micro-suite has been run. Used in...
6148 (Debugging a successful test, Debugging script and environment),
6149 (Debugging a failed test): ...these new tests. The first of these
6150 is fixed by...
6151 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6152 macro, split out from...
6153 (AT_INIT): ...here, so that using -d also generates a run script.
6154 Document that -d inhibits top-level logging.
6155 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6156 inhibits top-level logging; debug scripts are created.
6158 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6159 check.
6160 * tests/autotest.at (Empty test, Empty check): New test to check it.
6162 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6163 from gcc.
6165 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6167 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6168 the files if a problem appears. Make the empty *.at files
6169 read-only, too. Proposed by Ralf Wildenhues.
6171 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6173 * config/Makefile.am: Add comment to force updated Makefile.in.
6175 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6176 space only patch to this file, this patch causes the Makefile.in
6177 files that include freeze.mk to be updated, and thus have a
6178 newer time stamp again, which in turn makes a pristine CVS
6179 checkout have correct time stamps.
6181 * Makefile.maint (cvs-sv): New macro, to be used..
6182 (config.guess-url_prefix, config.sub-url_prefix)
6183 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6184 point to CVS text checkout of Gnulib files.
6185 (copyright-check): Bump current year.
6186 (announcement): Do not hard-wire `./announce-gen'.
6187 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6188 correctly.
6189 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6190 `chmod +x'.
6191 (wget_files): Update config.guess, config.sub, texinfo.tex by
6192 `wget-update', now that their URLs work again.
6194 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6196 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6197 Problem noted by Paul D. Smith.
6199 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6201 * doc/autoconf.texi: Remove unused words from word list.
6202 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6203 .x-sc_trailing_space: New files.
6205 * doc/standards.texi: Sync from gnulib.
6207 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6208 `LIBOBJDIR' as experimental.
6210 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6211 with a target directory; it's internally implemented as `cp'
6212 anyway, but since Autoconf advertises the possibility to use
6213 a target directory when LN_S is `ln -s', we need to find out.
6214 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6215 analyzed by Keith Marshall <keith.marshall@total.com>.
6217 * THANKS: Update.
6219 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6221 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6222 confdefs.h as-is. In general, if it has backslash-newline or the
6223 like, then it doesn't work either to sort or to remove empty
6224 lines.
6226 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6228 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6230 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6232 * lib/autom4te.in (Automake-preselections): Preselect
6233 _AM_SUBST_NOTMAKE.
6235 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6237 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6238 apostrophe within a single-quoted string, as this is the usual
6239 tradition and is easier to read than '"'"'. Don't rely on the
6240 shell treating "$/" like '$/'. Use a more-consistent indenting
6241 style for the trap.
6243 2006-04-09 Eric Blake <ebb9@byu.net>
6245 * tests/autotest.at (Backquote command substitution),
6246 (Multiline backquote command substitution): Remove mistaken
6247 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6248 applied...
6249 (Parenthetical command substitution, Multiline parenthetical
6250 command substitution): here.
6252 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6254 Import macros from gnulib (often changing their name).
6256 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
6257 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
6258 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

6261 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
6262 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
6263 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
6264 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
6265 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
6266 The manual mentions Gnulib more prominently.
6267 * doc/autoconf.texi (Gnulib): New node.
6268 (Pointers): Add Gnulib URL.
6269 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
6270 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
6271 Gnulib section.
6272 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
6273 suggest a #define rather than a typedef for _Bool, and mention
6274 Gnulib rather than trying to substitute stdbool code.
6275 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
6276 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
6277 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
6278 AC_STRUCT_DIRENT_D_TYPE.
6279 (Particular Types): Mention stdint.h and inttypes.h as standard
6280 headers too.
6281 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
6282 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
6283 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
6284 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
6285 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6286 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6287 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6288 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6289 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6290 (Coding Style). Don't mention m4_expand_once.
6291 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
6292 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
6293 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
6294 (AC_CHECK_FUNCS): Use it.
6295 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
6296 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
6297 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
6298 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
6299 (AC_HEADER_ASSERT): New macro.
6300 (AC_HEADER_STDBOOL): Don't assume "#error" works.
6301 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
6302 Catch a bug in an HP-UX C compiler.
6303 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
6304 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
6305 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
6306 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
6307 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
6308 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
6309 New macros.
6311 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
6312 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
6314 2006-04-08 Stepan Kasal <kasal@ucw.cz>
6316 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
6317 of the warning introduced by the 2001-08-28 change.
6319 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
6320 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6322 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
6323 variables shall be overriden by the cache.
6324 * tests/torture.at (AC_ARG_VAR): Test also with a first value
6325 that contains braces.
6327 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6329 Revert the patch from 2006-04-01 and only improve
6330 _AS_DETECT_BETTER_SHELL:
6332 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6333 skip nonexistent directories.
6334 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6335 only shell candidates which exist.
6336 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6337 * lib/autotest/general.m4 (AT_INIT): No need to give three
6338 parameters to _AS_PATH_WALK.
6340 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6341 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6343 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6344 distinguish m4sugar macros.
6345 * tests/tools.at (autoupdating with aclocal and m4_include):
6346 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6347 test case by Noah Misch <noah@cs.caltech.edu>.
6349 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6351 Revert my change from 2006-03-17, in other words:
6352 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6353 and DUALCASE=1.
6354 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
6355 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
6356 it is set.
6358 2006-04-07 Eric Blake <ebb9@byu.net>
6360 * doc/autoconf.texi (Programming in M4sh): Document that
6361 AS_MKDIR_P exits the script on failure.
6362 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6364 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6366 * config/elisp-comp, config/install-sh, config/mdate-sh,
6367 config/missing, config/mkinstalldirs: Sync from Automake.
6369 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
6370 from Automake.
6372 * doc/make-stds.texi: Sync from gnulib.
6374 2006-04-06 Eric Blake <ebb9@byu.net>
6376 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6377 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6378 2006-04-01.
6380 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
6381 Eric Blake <ebb9@byu.net>,
6382 Paul Eggert <eggert@cs.ucla.edu>,
6383 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6385 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6386 whether `set' quotes correctly: redirect stderr of the tested
6387 `set', and use a subshell, for Ultrix; use `sed' instead of
6388 `grep' for zsh `set' which may write binary output; match only
6389 at the beginning of a line, to avoid false positives.
6390 In order to avoid false positives by unrelated variables with
6391 multiline content, put the dump algorithm in a subshell and
6392 unset all variables containing newlines (except some which are
6393 special to the shell). Warn about cache variables that are
6394 unset.
6396 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6398 * config/config.guess, config/config.sub, config/texinfo.tex:
6399 Sync from upstream.
6401 * tests/mktests.sh: Reword comments.
6403 * tests/mktests.sh: Only skip internal macros starting with
6404 `_AC_' or `__AC_'. Noted by Stepan Kasal.
6405 Update exclusion lists for the test suite to this end:
6406 (AC_ARG_VAR): Do test this now.
6407 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6408 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6409 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6410 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6412 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6413 shell issue with double-quoted command substitutions of native
6414 commands.
6415 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
6416 Marshall.
6418 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
6419 no file matches the glob, discard the warning, set `nullglob'.
6420 (syntax-check): Likewise.
6421 (sc_cast_of_x_alloc_return_value): Likewise.
6422 (sc_cast_of_alloca_return_value, sc_error_exit_success)
6423 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
6424 (m4-check): Likewise.
6425 (sc_system_h_headers): Do not print rule on execution.
6426 (sc_tight_scope): Do not fail for non-existing `src' directory.
6427 (sc_changelog): Skip the Copyright footer.
6428 * lib/autoconf/lang.m4: Remove trailing space.
6430 * lib/autoconf/status.m4: More replacements to
6431 <tab><space> where this makes sense.
6433 2006-04-06 Stepan Kasal <kasal@ucw.cz>
6435 * tests/Makefile.am (maintainer-check-posix):
6436 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6438 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6439 ac_config_<foo>s again, sometimes normalized, sometimes not.
6440 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6441 (AC_CONFIG_COMMANDS): Do not do so here.
6442 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6443 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6444 2005-07-25 rewrite. Noticed by Noah Misch.
6446 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6447 _AC_PRESERVE_HELP_ORDER, ...
6448 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6450 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
6451 inside m4_expand_once; it is redundant.
6453 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6454 for --help from Cygnus `configure.'
6456 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
6458 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
6459 on a patch proposed by Ralf Wildenhues.
6461 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6463 * lib/autoconf/status.m4: Replace <space>''<tab> with
6464 <tab><space> where this makes sense.
6466 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
6467 Noah Misch <noah@cs.caltech.edu>
6469 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
6470 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
6471 * doc/autoconf.texi (Help Formatting): New node.
6472 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
6474 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6476 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
6477 lib/autoconf/specific.m4, lib/autoconf/status.m4,
6478 lib/autoconf/types.m4, lib/autotest/general.m4,
6479 tests/mktests.sh, tests/torture.at: White space cleanup:
6480 remove some SPACE before TAB, or add quoting ('' or @&t@).
6482 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
6484 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
6486 2006-04-05 Eric Blake <ebb9@byu.net>
6488 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
6489 empty test suite works.
6490 * tests/autotest.at (Empty test suite): Remove xfail.
6492 2006-04-05 Noah Misch <noah@cs.caltech.edu>
6494 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
6495 TAGS to ac_config_<foo>s.
6496 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
6497 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
6498 normalizing it, consistent it with previous releases.
6499 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
6501 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>

6506 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6508 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6509 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6510 Use 'comm' rather than N instances of grep; this also fixes a bug
6511 whereby substrings were incorrectly matched, causing us to not
6512 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6513 (exclude_list): Exclude empty macros.
6514 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
6516 Use awk rather than grep -E or egrep, to avoid

6519 Switch from grep to awk syntax.
6520 (ac_exclude_script): Renamed from ac_exclude_egrep.
6521 (au_exclude_script): Renamed from au_exclude_egrep.

6541 typedef'ed restricted pointer, to catch a compiler bug on
6542 HP-UX 11.x, and fix warnings so it passes with -Werror.
6543 (_AC_PROG_CC_C99): Likewise.
6544 Reported by Albert Chin <china@thewrittenword.com>.

6564 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
6565 to log, point to testsuite output tree.
6567 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>

6595 Clean up _AC_COMPILER_EXEEXT* macros.
6597 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6598 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6599 ac_file to the name of the default output file and call
6600 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6601 initial `rm' of the candidate files...
6602 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6603 the same list in subsequent `rm' calls, and for the temporary
6604 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6605 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6606 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6607 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6608 no longer needed) by libtool. Make it a cache check.
6609 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6610 copied here by mistake.
6611 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6612 _AC_COMPILER_EXEEXT.
6613 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6614 _AC_COMPILER_OBJEXT directly.

6646 Autoconf version number despite a zero- or one-argument AC_INIT.
6648 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
6649 subordinate tools.
6650 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
6651 * doc/autoconf.texi (autoreconf Invocation): Document it.
6653 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

6665 the correct lines of the input file by subtracting..
6666 (_au__first_line): ..this new definition.
6668 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
6669 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
6670 Remove stray newline in output.
6671 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also

6680 hairy details.
6681 The AC_LANG_SAVE issue was reported against Libtool by
6682 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
6683 Kristian Kvilekval <kris@cs.ucsb.edu>.
6685 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6687 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
6688 switch all of them on and of when necessary. Fixes the bug when
6689 m4sugar macros (e.g., m4_define) were expanded after the first
6690 automatic update (e.g., after AC_PREREQ or AC_INIT).
6692 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>
6694 * doc/autoconf.texi (Programming in M4sh): Sharpen the descriptions

6723 (File System Conventions): Put discussion of // versus / here, and
6724 modernize it a bit.

6737 2006-03-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6739 * bin/autoscan.in: The value of find_configure_ac should be
6740 checked for existence, so we don't barf over a nonexisting
6741 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
6743 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6808 (AC_CHECK_SIZEOF, AC_CHECK_SIZEOF struct): Use it.

6887 trying to execute the command `no'.
6889 * lib/autoconf/lang.m4 (AC_LANG_CONFTEST): AC_DEFUN this, not

7391 outsmarting the old heuristic. Problem reported by
7392 Mikulas Patocka.
7394 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7396 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
7398 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
7400 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
7401 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
7403 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7405 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7406 before removing it (chmod -R u+rwx); there are three instances of this.
7408 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7409 Stepan Kasal <kasal@ucw.cz>
7411 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7412 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7413 make its content writable before removing it. Remove an errorneous
7414 comment from the end, where the logs of the failed tests are copied
7415 to the main log file.
7417 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7419 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7420 in case the computer is too quick. Double quote the configure.ac
7421 snippets.
7423 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7424 problems if the testsuite were running too fast.
7426 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7428 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7429 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7430 (which belong to Xt, not X itself). See Debian bug 327655.
7431 * NEWS: Mention this.
7433 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7435 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7437 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7439 * config/move-if-change: Don't output "$2 is unchanged";
7440 suggested by Ben Elliston. Handle weird characters correctly.
7442 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7444 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7445 calls, so that the final expansion of this macro is shorter.
7446 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7447 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7448 the cleanup there. Use AS_VAR_* macros, to be more general.
7449 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7451 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7453 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7455 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7457 * doc/autoconf.texi (Configuration Headers): Add an index entry
7458 for AH_HEADER.
7460 2005-08-26 Pavel Roskin <proski@gnu.org>
7462 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
7463 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7464 running xmkmf.
7466 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7468 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7469 The previous patch didn't work, so try a better one.
7471 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7473 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7474 in the example. Reported by Bruno Haible.
7475 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7476 "if $undefined_var;" succeeds with my shell.
7478 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7479 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7480 but change the m4_divert_text to m4_divert_once.
7482 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7484 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7485 Work around bug in Solaris /usr/xpg4/bin/awk.
7486 The bug is present in at least Solaris 8 through 10.
7488 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7490 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7491 some evil values and relying on the fact that $* concatenates the
7492 parameters by the first character from IFS.
7494 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7495 Stepan Kasal <kasal@ucw.cz>
7497 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7498 first header appears, define AH_HEADER.
7499 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7500 Update limitations about when to call AC_CONFIG_HEADERS.
7501 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7502 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7503 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7504 ``Configuration Actions''; fix their index entries.
7506 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7507 options correctly. Process N-M as M-N if M is smaller than N.
7508 Process ranges correctly so that N-N will run only N.
7509 Sort and uniquify the tests that will be run. If there is more
7510 than one test, reinsert the banners for the tests.
7511 * tests/autotest.at (Keywords): Unmark XFAIL.
7513 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7515 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7516 before passing the macro name to AH_TEMPLATE.
7518 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7519 now opens log after option processing; in particular, --version
7520 and --help do not touch config.log.
7522 * Makefile.maint: Revert the change from 2005-08-12.
7524 2005-08-22 Stepan Kasal <kasal@ucw.cz>
7526 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
7527 common code to...
7528 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
7530 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7532 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7533 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7534 Language cleanup.
7536 * doc/autoconf.texi (Defining Symbols, Changed Results):
7537 Prepend to LIBS, not append, in examples.
7539 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7541 When building in place, set srcdir="."; suggested by Tim Van Holder.
7543 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7544 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7545 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7546 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7547 does not mean "no --srcdir option".
7549 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7551 * tests/autoscan.at (autoscan): New file.
7552 * tests/suite.at: Use it.
7553 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7554 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7556 * tests/autotest.at (Keywords): Test keywords combinations.
7558 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7560 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7561 add "2>&1"; gzip 1.2.4 prints help on stderr.
7563 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7565 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7566 was pushdef'ed twice while popped only once. Push it only once.
7567 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7569 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7571 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
7572 prefixed by mere "===", not "configure: === ".
7574 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
7576 * Makefile.maint: Update from Bison.
7578 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7579 "<tab>" in comment, so that the point is understandable.
7581 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7583 Rewrite substantial part of lib/autoconf/status.m4.
7584 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7585 and CONFIG_COMMANDS are not processed in four separate loops.
7586 Instead, there is one main loop. This alows that the common code
7587 is expanded only once, thus config.status (and configure) is smaller.
7589 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7590 the AC_LIST_FILES and cousins macros are no longer used.
7592 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7593 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7594 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7595 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7596 contain the initialization, nor the for loop, nor the associated
7597 commands; all these go to ...
7598 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7599 _AC_OUTPUT_CONFIG_STATUS.
7600 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7601 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7602 (_AC_OUTPUT_FILE): The creation of the sed script ...
7603 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7604 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7605 _AC_OUTPUT_MAIN_LOOP.
7606 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7607 _AC_CONFIG_COMMANDS): Use ...
7608 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7609 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7610 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7611 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7612 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7613 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7614 ... new macros.
7615 (_AC_CONFIG_UNIQUE): Update.
7616 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7617 Replaced by this ...
7618 (_AC_LIST_TAGS): ... new common macro.
7619 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7620 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7621 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7622 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7623 this didn't belong to the `config commands' section.
7624 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7625 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7626 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7627 to the `config commands' section either.
7628 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7629 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7631 ... and many changes to the comments nearby.
7633 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7634 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7635 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7636 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7637 (#define header templates): The comment at the top of the generated
7638 header now includes the name(s) of the source file(s).
7640 Several unrelated small changes:
7642 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7643 parameter to AC_DIAGNOSE.
7644 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7645 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7646 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7647 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7648 with AU::AC_OUTPUT.
7649 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7650 in AC_OUTPUT doesn't double-quote it either.
7651 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7652 parameters.
7654 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7656 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7657 versions of Portland Group compiler produce single- and double-quoted
7658 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7659 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7661 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7663 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7664 This is a corrected version of yesterday's patch.
7666 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7668 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
7669 path, too; insert a "===" to emphasize the line.
7671 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
7672 ac_cv_build_alias to ac_build_alias.
7673 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7675 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7676 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7677 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7678 (AC_ARG_VAR): ... here.
7679 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7680 target_alias.
7682 Keep a list of all precious variables and process them with one simple
7683 for loop, instead of expanding all commands, or, OTOH, complicated
7684 processing of output of "set".
7685 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
7686 variable names in new macro...
7687 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
7688 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
7689 a loop to assign all ac_env_* and ac_cv_env_* variables.
7690 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7691 to INIT_PREPARE.
7692 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7693 its value to shell variable ac_precious_vars and call
7694 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
7695 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
7696 _AC_ARG_VAR_VALIDATE.
7698 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
7699 and the AC_SUBSTs ...
7700 (AC_INIT): ... here.
7702 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
7703 the ac_subst_files section in config.log.
7705 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
7707 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>
7709 * NEWS: New macro AC_C_TYPEOF.
7710 * doc/autoconf.texi (C Compiler): Document AC_C_TYPEOF.

7714 Fix problems reported by Nicolas Joly.
7715 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
7716 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7717 They are generated by the Tru64 v5.1B shell.
7719 2005-07-05 Stepan Kasal <kasal@ucw.cz>
7721 Fix my changes from 2005-07-01; reported by Noah Misch.
7722 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
7723 description, the macro now accepts only a single tag.
7724 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
7726 Fix cases when the varsions of Autoconf and Autotest don't match.
7727 Reported by Noah Misch.
7728 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
7729 at_top_builddir, for compatibility with older autotest.
7730 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
7731 is not set, use at_top_builddir, for compatibility with older
7732 versions of autoconf.
7734 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7736 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
7737 Problem reported by Patrick Welche.
7739 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
7741 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7742 sed substitution command, so that we allow | in program prefixes
7743 and program suffixes. (& is a problem anyway; we're not fixing
7744 that here.)
7745 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
7746 configure_input, top_builddir, srcdir, etc.
7747 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7748 PATH_SEPARATOR in AUTOTEST_PATH.
7750 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
7752 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
7753 for loop over config.site files using `set', to allow
7754 directory names containing IFS characters.
7756 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
7758 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
7759 directories with weird names. Apparently some people like living
7760 on the edge. However, improve the test that "pwd" actually does
7761 report a name for the working directory.
7762 * NEWS: Remove the claim that we test for funny chars in dir names.
7764 2005-07-01 Stepan Kasal <kasal@ucw.cz>
7766 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
7767 replaced ...

7776 about #include <config.h>.
7777 (Generic Functions): Mention the Gnulib project.
7778 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
7780 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
7781 document to output the default config_* lists to config.status.
7782 Don't recognize option --file, if the functionality is not there.
7783 Likewise for --header; moreover, recognize --he and --h as shortcuts
7784 for --help in that case.
7786 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7787 matches the order of execution. No code changed.
7789 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7791 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
7792 single-quoted -cmdline argument in Portland Group compiler.
7793 Reported against LAM by Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7795 2005-06-30 Alexandre Duret-Lutz <adl@gnu.org>
7797 * lib/autom4te.in (Automake-preselections): Preselect AC_SUBST_TRACE.
7799 2005-06-29 Stepan Kasal <kasal@ucw.cz>
7801 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
7802 descriptors to child processes; reported by Norman Gray.
7804 2005-06-29 Stepan Kasal <kasal@ucw.cz>
7806 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
7808 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
7809 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7810 (AC_SUBST): Call it.
7811 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7812 the directory specific variables; but don't call it for configure_input.
7814 2005-06-28 Derek Price <derek@ximbiot.com>
7816 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7817 addition.
7819 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7821 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
7822 directory have inherent problems with special characters like spaces,
7823 due to limitations in Make syntax. Problem reported by Alexandre
7824 Duret-Lutz.
7825 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
7826 Also, fix Tru64 porting problem with shell patterns,
7827 reported by Ralf Wildenhues.
7829 2005-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7831 * doc/autoconf.texi (Subdirectories): Fix markup typos.
7833 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7835 * tests/local.at (AT_CHECK_ENV): Simplify regexp slightly.
7837 Fix some more shell quoting problems. Prompted by a bug report
7838 from Justace Clutter.
7839 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7840 variable into diagnostic. Make the diagnostic an error, not a warning,
7841 because we really don't support spaces and suchlike in dir names.
7842 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7843 Don't worry about backslashes in srcdir; it can't happen now.
7844 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.

7854 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
7856 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
7857 that '\|' is not allowed in BREs; recommend using newline separated

7872 (Special Shell Variables): Fix sed code this in the example.
7873 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7874 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
7876 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
7877 expand to the empty list. Don't use two pairs of m4_changequote,
7878 it's not necessary.
7880 2005-06-20 Derek Price <derek@ximbiot.com>
7882 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
7884 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
7886 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
7887 * doc/autoconf.texi:
7888 Don't mention Solaris versions so much, if a
7889 problem is common to all extant versions of Solaris. Say "SunOS
7890 4" instead of "SunOS" for SunOS 4.
7891 (awk): Mention more of the limitations of traditional Awk.
7892 (cat): Don't talk about cat -v.

7905 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
7906 Use shell builtins rather than 'expr', to work around expr bug.
7908 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
7910 * doc/autoconf.texi: "filesystem" -> "file system".

7919 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
7920 (.x.1): Ignore the time stamp in the .TH line when deciding whether

7934 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7935 -u, since it outputs chatter if the input files are the same.
7936 Problem reported by Ralf Menzel.
7938 2005-06-08 Derek Price <derek@ximbiot.com>
7940 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7941 renaming them since they are about to be redefined anyhow.
7943 2005-06-08 Derek Price <derek@ximbiot.com>
7945 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7946 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7947 Move m4_undefine to alphabetical order.
7949 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
7951 * README: Recommend GNU M4 1.4.3 or later.
7952 * doc/autoconf.texi (Introduction): Likewise.
7953 Reword to avoid some formatting glitches.
7954 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7955 Clarify explanation of HP compiler bug.
7956 Redo example output tp match current CVS snapshot.
7957 Use @example.org in email addresses when the examples
7958 might get inadvertently cut-and-pasted into user code.
7959 Remove example of autom4te usage that doesn't seem to work now.
7960 Use modern AC_INIT (except when the example is meant to be
7961 shown with Autoconf 2.13).
7962 Update ksh info for Solaris 9 and later.
7963 KB -> kB.
7964 Modernize description of Automake versions a bit.
7965 Don't claim a future version of Autoconf is near.

7971 follows its own advice about quoting better.
7972 Reword to avoid some formatting glitches.
7973 * doc/installt.exi: Reword to avoid some formatting glitches.
7975 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7976 Tru64 ksh pattern matching bug. Reported against Libtool by
7977 Albert Chin <libtool@mlists.thewrittenword.com> and
7978 Nicolas Joly <njoly@pasteur.fr>.
7980 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7982 m4_cdr of one-member list was [[]] (one-member list containing an
7983 empty string) instead of [] (an empty list. Callers were skewed to
7984 match this misbehaviour. As a consequence of this:
7985 - m4_foreach([x], [], [foo]) expanded to `foo', while
7986 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7987 This bug has been fixed:
7989 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7990 expand to an empty string; print error msg if called without
7991 an argument list.
7992 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7993 misbehaviour; handle [] and [[]] correctly.
7995 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7997 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

7999 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
8001 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
8003 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8004 swallow records with more than 99 fields.
8005 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8006 parse the long line.
8008 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8010 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
8011 swallow literals longer than 399. Reported by Ralf Wildenhues.
8012 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
8013 to workaround this limitation.
8015 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
8017 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
8018 to gfortran, and make these the first two compiler names
8019 checked (following the general autoconf preference for gcc).
8021 2005-06-03 Stepan Kasal <kasal@ucw.cz>
8023 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
8024 (DISTCLEANFILES): Remove $(check_SCRIPTS).
8025 (testsuite): Make sure autotest.m4f is up-to-date before using it.
8027 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
8029 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
8030 expression of unbounded size when processing the --list
8031 option. This runs afoul of a limit of 399 bytes per regular
8032 expression on AIX. Problem reported by Ralf Wildenhues.
8034 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
8036 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
8037 * doc/autoconf.texi (Particular Headers): Reword example
8038 for multiline stdbool replacement.
8039 (Setting Output Variables): Reword text a bit. Don't
8040 give all the details about |#_!!_#|.
8041 Reword description of line replacement.
8043 2005-05-31 Dan Manthey <dan_manthey@partech.com>
8045 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
8046 now contain newlines, and substituted files must be referenced on
8047 a line alone; the sed scripts to substitute them are now very
8048 different.
8049 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
8050 commands can be put in a sed script portably.
8051 * doc/autoconf.texi (Setting Output Variables): Document above
8052 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
8053 use of multiline substitution.

8063 * tests/local.at: Don't attempt to check for negated character
8064 classes in shell scripts. The test was too brittle.
8066 2005-05-25 Stepan Kasal <kasal@ucw.cz>
8068 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
8069 * doc/autoconf.texi (Limitations of Builtins): Document this
8070 limitation.
8072 2005-05-24 Stepan Kasal <kasal@ucw.cz>
8074 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
8075 common code; used in many places in the tree.

8082 messages when ac_unique_file is not found.
8083 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
8084 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
8085 commands, for consistency with AC_MSG_ERROR and such.
8087 * bin/autoconf.as: Make more use of "shift 2" in option processing.
8089 * bin/Makefile.am: Merge the two rules for creating scripts.

8097 2005-05-20 Stepan Kasal <kasal@ucw.cz>
8099 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
8100 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8101 (ac_top_builddir): ... this ...
8102 (ac_top_build_prefix): ... to this; the old name is also kept, for
8103 backward compatibility.
8104 (ac_top_builddir_sub): New variable, without the trailing slash,
8105 always nonempty.
8106 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
8107 * doc/autoconf.texi (Configuration Actions): Rename
8108 ac_top_builddir to ac_top_build_prefix.
8109 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
8110 at_top_builddir to at_top_build_prefix.

8116 of confdefs.h .
8118 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8120 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8121 argument to m4_foreach. I guess it was necessary in the past,
8122 but I think it's a no-op now.
8124 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8126 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8127 ``cat <<_ACEOF'' commands to one.
8128 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
8129 * lib/autoconf/status.m4: On various places, use expr instead of
8130 ``echo|sed.''
8131 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
8132 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
8133 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8134 a range.
8135 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8136 the wrong patterns between ``case'' and ``esac.'' The previous
8137 code had false positives.
8139 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
8141 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
8142 as on 2005-05-02.
8143 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
8144 Mention LIBOBJDIR.

8206 quoting rules. Problems noted by Stepan Kasal.
8207 Also, throughout this document, be more careful about white space.
8208 "blank", "white space", and "space" all have different meanings
8209 and we should be careful to say what we mean.
8211 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
8213 Fix C++ related problems reported by Werner Lemberg.
8214 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

8261 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8262 comment and reduce m4_default([foo], []) to [foo].
8263 (m4_strip): Update the explanation.
8265 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8267 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):

8270 * lib/autoconf/functions.m4
8271 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8272 Don't bother to remove core files; AC_RUN_IFELSE should do that
8273 for you.
8275 2005-04-19 Stepan Kasal <kasal@ucw.cz>

8294 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8296 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8297 as well as configure.in. Problem reported by Gregorio Guidi.
8299 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8301 * doc/autoconf.texi (Particular Functions): Use gnulib's current
8302 pattern for alloca snippet.
8304 2005-04-04 Stepan Kasal <kasal@ucw.cz>
8306 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

8315 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
8317 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8319 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8320 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8321 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8322 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8323 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8325 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8327 * NEWS: The configure command now warns you if you attempt to use
8328 a directory whose name contains a special character like space,
8329 newline, or "\".
8330 * doc/autoconf.texi (Installation Directory Variables): Allow
8331 "," in file names. Do not use \@; it's not a portable regexp.
8332 * bin/Makefile.am (edit): Likewise.
8333 * lib/Makefile.am (edit): Likewise.
8334 * tests/Makefile.am (edit): Likewise.
8335 * tests/semantics.at: Likewise.

8339 * doc/autoconf.texi (File System Conventions): Warn about
8340 unportable file names.
8341 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8342 (AC_INIT): Use it.
8343 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8344 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8345 ac_pwd, and quote srcdir.
8346 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8348 * doc/autoconf.texi: Fix some systematic formatting problems.
8349 ".)" needs a following @: if not at the end of a sentence, and
8350 similarly for "!)". "etc." should be preceded by a comma.
8351 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8353 2005-03-22 Bruno Haible <bruno@clisp.org>
8355 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8356 argument is often called 'build-aux'.
8358 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8360 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8361 macro AC_TRY_LINK is obsolete.
8362 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8363 `AC_CONFIG_FILES'.
8365 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8367 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8368 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8369 from a Common Lisp's `cl'.
8370 (AC_PROG_CXX): Behave according to the documentation: don't
8371 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8372 make the variable CCC precious; use `cl.exe', not `cl'.
8374 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8375 Alexandre Duret-Lutz <adl@gnu.org>
8377 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8378 /dev/null, as "configure" shouldn't read stdin, and this insulates
8379 us from problems (e.g., when testing for "cl"). Also, do this
8380 redirection before invoking "hostname" or "uname", and keep the
8381 original input stream available via...
8382 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8383 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8384 bother with "</dev/null" since it's now done at the top of
8385 'configure'.
8386 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8387 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

8393 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8395 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8396 newline if neither \c nor -n work, as that would output two
8397 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8399 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8401 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8402 This causes that any required macros inside will get before the if.
8403 * doc/autoconf.texi (autom4te.cache): A typo.
8405 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8407 Undo previous change, except keep the change to
8408 lib/autoconf/programs.m4 that replaced grep with shell
8409 pattern-matching. This is because net-snmp configure reads stdin.
8410 Reported by Noah Misch.
8412 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8414 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8415 from /dev/null, as "configure" shouldn't read stdin, and this
8416 insulates us from problems (e.g., when testing for "cl").
8417 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8418 before invoking "hostname" or "uname".
8419 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8420 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8421 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8422 "</dev/null" since it's now done at the top of 'configure'.
8423 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8424 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8425 Also, replace grep with shell pattern-matching, to save a process.
8427 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8429 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8430 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8431 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8432 compiler.
8434 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8436 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8437 grep -q isn't portable. Improve grep -s explanation.
8438 Problem reported by Dan Manthey.
8440 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8442 * doc/autoconf.texi (Special Shell Variables): Clarify
8443 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8445 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8447 * doc/autoconf.texi: Use @acronym for DJGPP.
8448 Fix some @code's that should have been @env's, and vice versa.
8449 Sort environment variable names.
8450 Mention that shells no longer inherit IFS.
8451 Don't recommend PATH_SEPARATOR=';' so strongly.
8452 Mention that $RANDOM might expand to the empty string.
8453 "symlink" and "soft link" -> "symbolic link".
8454 Improve mktemp description (reported by Bruno Haible).
8456 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8458 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8459 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8460 Likewise.
8461 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8462 Likewise.
8464 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8466 * NEWS: Mention AT_COPYRIGHT.
8468 * tests/local.at (AT_CMP): Use diff directly on input files rather
8469 than copying them.
8471 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8472 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8474 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8475 and Paul Eggert <eggert@cs.ucla.edu>
8477 * tests/autotest.at (Empty test suite): New test.

8484 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8485 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8486 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8487 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8488 (Standard regular expressions): New test.
8489 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8490 excess test name quoting.
8491 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8492 CPPFLAGS to `configure' instead of setting it in `configure'.
8494 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8495 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8496 on some platforms.
8498 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8499 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

8527 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8529 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8530 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8532 Try not to generated lines of unlimited length, as POSIX places a
8533 2047-byte limit on line length of portable text files.
8534 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8535 Use newline as a separator, not space.
8536 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
8537 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
8538 space.
8540 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8542 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
8543 as_func_*. Add test to check whether positional parameters
8544 are restored after function return.
8546 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
8548 * doc/autoconf.texi (Special Shell Variables): Mention _,
8549 BIN_SH, DUALCASE. Say that variables other than "status" are safe
8550 if they contain a lower-case letter. The DUALCASE problem was
8551 reported by Ralf Wildenhues.
8553 * bin/autoconf.as: Don't exit with status 0 after write failure
8554 with --help or --version.
8555 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

8561 Unicos 9 sed limitations.
8562 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

8564 Fortran 95 (newer Crays).
8566 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
8568 * man/Makefile.am (.x.1): Go back to the simple solution, but take
8569 care to echo the commands, so the user knows what's going on.
8570 Modified from a suggestion by Stepan Kasal.
8572 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

8580 Based on a proposed patch by Ralf Wildenhues.
8582 * man/Makefile.am (.x.1): Make sure the required generated files
8583 are up to date. Problem and original solution proposed by Stepan Kasal.

8591 2005-01-29 Stepan Kasal <kasal@ucw.cz>
8593 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8594 Update the long comment explaining it.
8596 m4_require no longer writes an ``is required by'' line to the
8597 execution stack. It contains only one bit of non-redundant
8598 information: that the macro was required, not called. And even
8599 this bit is useless in most situations: have you ever met a macro
8600 which both calls and requires the same macro?
8602 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8603 (_m4_defun_pro_outer): ... only via this macro, for the outermost
8604 macro.
8605 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
8606 (m4_expansion_stack_pop): Remove the misplaced comment.
8607 (m4_require): Don't put the ``is required by'' line to the
8608 execution stack; slightly improve the out-of-a-defun error message.
8609 (_m4_divert_grow): New macro, counter for the temporary diversions.
8610 (_m4_require_call): Use it.
8611 * tests/m4sugar.at (m4_require): Expect output without the
8612 ``is required by'' messages.
8614 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8616 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
8617 rather than x for expr.
8619 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
8620 this is safe.
8621 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
8622 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

8633 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
8634 from masters, so that FileUtils.pm's update_file provide --force
8635 support.
8636 * bin/autoheader.in: Pass $force to update_file so that
8637 config.h.in is always recreated when --force.
8639 2005-01-24 Stepan Kasal <kasal@ucw.cz>
8641 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
8643 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
8645 * doc/autoconf.texi (Limitations of Builtins): Clarify that
8646 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
8648 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
8650 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
8651 Warn about newline stripping in `` and $(). Update Solaris
8652 version to 9.
8653 (Limitations of Builtins): Use expr "X...", not expr "x...", as
8654 X insulates us from future changes to Posix.
8655 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
8656 stripping.
8658 2005-01-19 Stepan Kasal <kasal@ucw.cz>

8676 ulongval to be static, to avoid unwanted GCC warning. Problem
8677 reported by Michael Jennings via Daniel Reed; see
8678 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
8680 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
8682 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
8683 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
8684 datadir, infodir, and mandir. Adjust argument parsing code.

8687 new variables.
8689 2005-01-04 Noah Misch <noah@cs.caltech.edu>
8691 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
8692 not seem to work, assume it does set $(MAKE).
8693 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
8695 2005-01-03 Stepan Kasal <kasal@ucw.cz>
8697 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

8703 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
8704 (_m4_divert_n_stack): New macro; the expansion is
8705 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
8706 otherwise.
8707 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
8708 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8709 stored in _m4_divert_diversion or _m4_divert_dump.
8710 (m4_divert_pop): When the parameter is given, compare the symbolic
8711 name with the last diversion pushed on the stack. Previously, the
8712 current diversion was compared with the numeric value of the
8713 diversion given as the parameter.
8714 (m4_require): If the macro hasn't been expanded yet, call ...
8715 (_m4_require_call): this new macro.
8717 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9022 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use

9202 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9204 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9205 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9206 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9207 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9209 More fixes to support spaces in the name of the build directory.
9210 This isn't a complete fix but it's an improvement.
9212 * bin/autoconf.as (autom4te_options): New var.
9213 Use it instead of appending to AUTOM4TE, so that we can allow
9214 spaces in the build directory's absolute name.
9215 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9216 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9217 AT_CHECK_NOESCAPE): Likewise.
9218 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
9219 main program): Likewise.
9221 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
9223 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
9224 From Ralf Corsepius in:
9225 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
9227 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
9229 * doc/autoconf.texi (Function Portability): Document isinf and
9230 and isnan. From a suggestion by Kevin Ryde.
9232 * lib/Autom4te/General.pm (END): Return correct exit status even
9233 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9235 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9237 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9238 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9239 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9241 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9243 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9244 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9245 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9246 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9247 * lib/autom4te.in (Automake-preselections): Preselect
9248 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9250 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9252 * lib/autom4te.in (Automake-preselections): Preselect
9253 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
9254 trace them.
9256 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
9258 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
9259 Tru64.
9260 * doc/autoconf.texi (Shellology): Mention BIN_SH.
9261 Document problem with "`""`" in pdksh POSIX mode.
9263 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9265 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9266 with pdksh, too. Problem reported by Patrick Welche via
9267 Gary V. Vaughan.
9268 * doc/autoconf.texi (Shellology): Note that set -o posix is
9269 useful for pkdsh, too.
9271 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9273 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9274 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9275 Don't fail if ENV or BASH_ENV is readonly.
9276 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9277 etc. are read only. Problem reported by Ludovic Courtes.
9279 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9281 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9282 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9283 (trivial change)
9285 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9287 * doc/autoconf.texi (File System Conventions): Warn about
9288 names like "aux". Problem reported by Eric Blake.
9290 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9291 by zero instead of array size, so that we can use any arithmetic
9292 constant expression (instead of requiring an integer constant
9293 expression). This allows us to test expressions like DBL_MAX <
9294 LDBL_MAX, which didn't conform to the C standard using the old
9295 method.
9296 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9297 now that we can do floating-point tests at compile time.
9299 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9301 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9302 and LDBL_EPSILON, as the resulting expression isn't an
9303 integer constant expression and violates the C standard.
9304 Problem reported by Nelson H. F. Beebe. Also, check
9305 for "L" suffix, and check that long double doesn't have
9306 worse range or precision than double, that mixed-mode
9307 arithmetic doesn't generate a diagnostic, that double
9308 constants fit in long double.
9310 2004-06-03 Kevin Ryde <user42@zip.com.au>
9312 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9313 malloc(0) and realloc(NULL,size).
9315 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9316 Bob Proulx.
9318 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9320 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9321 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9322 by Jim Meyering.
9324 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9326 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9327 can be rewritten using if-then-else. Suggested by Bruno Haible.
9329 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9331 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9332 Problem reported by Stepan Kasal.
9334 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9336 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9337 change). Patch reported by Ralf Wildenhues in
9338 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9340 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9341 function F exists if the compiler and linker let you compile an
9342 expression like (F != 0). Recent versions of GCC optimize away
9343 the reference to F in that case, since every function address must
9344 be nonzero, so the link succeeds even if F does not exist.
9345 Problem reported by Manu in
9346 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9348 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9349 "Unix". Many uses changed.
9350 (Limitations of Builtins): Explain better why the ! command isn't
9351 portable.
9353 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9355 * lib/autom4te.in (Automake-preselections): Preselect
9356 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9358 2004-05-19 Kevin Ryde <user42@zip.com.au>
9360 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9361 referencing AC_FUNC_STRERROR_R.
9363 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9364 note pessimistic assumption when cross compiling.
9366 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9368 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9369 (until 2004) invoked subcommands with sh -e, contra POSIX.
9370 Reported by Kevin Ryde.
9372 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9374 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9375 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9376 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9377 `test -f " /usr/bin/grep"', which _always_ failed.
9378 (AC_PROG_SED): Ditto bogus PATH fix.
9379 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9380 requires that grep correctly supports _multiple_ `-e' options, rather
9381 than stating only that grep should accept `-e'.
9383 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9385 Port to C99, which requires that 'exit' be declared.
9387 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9388 to ensure that stdlib.h is included.
9389 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9390 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9391 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9392 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9393 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9394 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9395 when using 'exit' in a test; C99 requires that 'exit' be declared.
9397 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9399 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9400 now prefers 'grep' implementations that accept -e.
9401 (Limitations of Usual Tools): Describe problems of traditional
9402 egrep and fgrep with long input lines, and of traditional grep
9403 with -e.
9404 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9405 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9406 All callers changed. Append /usr/xpg4/bin to the PATH, for
9407 Solaris.
9408 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9409 the user with complaints about multiple -e options.
9410 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9411 Define it with AC_PROG_GREP.
9412 * configure.ac (AC_PROG_GREP): Add.
9413 * lib/freeze.mk (GREP): New macro.
9415 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9417 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9418 a possible candidate only after all others fail, rather than
9419 consulting it first. This improves backward compatibility by
9420 better reflecting the way shell selection occurred in previous
9421 versions of Autoconf, and should help to avoid triggering latent
9422 problems in other packages, such as the one in Automake where zsh
9423 is not handled robustly:
9424 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9425 Although it is not Autoconf's responsibility to work around
9426 problems in Automake, it nevertheless makes sense to avoid
9427 introducing unnecessary incompatibilites.
9429 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9430 Gary V. Vaughan <gary@gnu.org>
9432 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9433 how deeply nested we are when a suitable tool is found, set the
9434 ac_path_TOOL_found flag.
9435 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9436 nested we are in this macro. Break out of all 3 nested loops if
9437 ac_path_TOOL_found is set.
9439 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9441 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9442 of the _AS_PATH_WALK loop too if GNU flavor is found.
9444 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9446 * doc/autoconf.texi (Limitations of Make): Update documentation
9447 for `$<'. New entry `Long lines', based on a report from Simon
9448 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9449 paragraph about DJGPP, based on a mail from Richard Dawe.
9451 2004-04-20 Paul Eggert <eggert@twinsun.com>
9453 * tests/c.at (C keywords): Don't assume that GCC supports
9454 "restrict" and "inline", as sufficiently-old GCC versions do not
9455 (also, GCC configured to be in pedantic C89 mode does not).
9456 Problem reported by Sumit Pandya in:
9457 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9459 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9460 consider -g to work if it generates warnings when plain compiles
9461 don't. Problem reported by Braden McDaniel in:
9462 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9464 * doc/autoconf.texi (Slashes): New section, to document a problem
9465 reported by Jim Meyering in:
9466 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9468 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9469 linker output files before linking, to work around IRIX 6 linker bug.
9470 Problem reported by Rainer Orth in:
9471 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9473 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9475 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9476 best tool so far counter rely on the tool path variable name to
9477 avoid checks for one tool being affected by the results of running
9478 the length check on a previous tool.
9480 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9481 match expression argument, as different greps have different
9482 regular expression flavours.
9483 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9484 literals.
9485 (AC_PROG_EGREP): Pass 'EGREP$'.
9486 (AC_PROG_GREP): Pass 'GREP$'.
9488 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9490 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9491 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9493 2004-03-29 Paul Eggert <eggert@twinsun.com>
9495 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9496 Types, Specific Compiler Characteristics, System Services,
9497 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9498 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9499 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9500 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9501 Likewise.
9502 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
9503 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
9504 AC_TYPE_OFF_T): Likewise.
9505 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
9506 Likewise.
9508 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
9509 pacify libtool 1.5.2. Fix quoting problems in sed command.
9511 2004-03-28 Paul Eggert <eggert@twinsun.com>
9513 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9514 now defines HAVE_DECL_TZNAME if it is declared, when
9515 HAVE_STRUCT_TM_TM_ZONE is not defined.
9516 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9517 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9518 for HAVE_TZNAME.
9520 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
9522 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
9523 superfluous backslashing of quotes (") in sed expressions;
9524 thanks to Paul Eggert.
9526 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
9528 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9529 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9530 H. F. Beebe for the bug report.
9532 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9534 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9535 quoted -cmdline argument in Portland Group compiler (bug
9536 reported by Jeffrey J. Barteet).
9538 2004-03-25 Kevin Ryde <user42@zip.com.au>
9540 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
9541 (Run Time): ... here, where it's now mentioned.
9543 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
9545 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
9546 inherits from language Autoconf-without-aclocal-m4.
9547 (Customizing autom4te): Adjust example; the cache must now be
9548 disabled for language Autoconf-without-aclocal-m4.
9550 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
9551 Nathanael Nerode <neroden@twcny.rr.com>
9553 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
9554 AC_CHECK_TOOLS): Warn if a cross-tool is found without
9555 a prefix.
9556 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
9557 AC_CHECK_TARGET_TOOLS): New macros.
9558 * doc/autoconf.texi (Generic Programs): Document
9559 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
9560 AC_CHECK_TARGET_TOOLS, and warn for future changes
9561 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
9562 AC_CHECK_TOOLS.
9563 (Specifying Names): Document the reason for these future
9564 behavioral changes.
9565 * tests/mktests.sh: Do not generate tests for the
9566 new macros.
9567 * NEWS: Document these changes.
9569 * doc/autoconf.texi: Avoid macros with unbraced arguments,
9570 they make TeX hang up.
9572 2004-03-15 Paul Eggert <eggert@bogus.example.com>
9574 * NEWS: New macro AC_CHECK_ALIGNOF.
9575 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
9576 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
9577 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
9578 vowel.
9579 (AC_CHECK_ALIGNOF): New macro.
9580 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
9581 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
9582 those for sizeof.
9584 2004-03-03 Paul Eggert <eggert@twinsun.com>
9586 * bin/Makefile.am (edit): Don't use $< in a context where
9587 POSIX doesn't require support for it. Use $@.in instead.
9588 Problem reported by Anthony N. Frasso in
9589 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
9590 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
9592 2004-02-23 Gary V. Vaughan <gary@gnu.org>
9594 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
9595 from the next generation of Libtool.
9596 * lib/autom4te.in (Autoreconf-preselections): Ditto.
9598 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9600 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
9601 is not always thread-safe. Report from Nathanael Nerode.
9603 2004-02-18 Paul Eggert <eggert@twinsun.com>
9605 Fix a dependencies problem, stemming from a Autoconf 2.59 build
9606 problem on QNX reported by Stephen Rasku in
9607 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
9609 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
9610 $(m4sh_m4f_dependencies); this removes a FIXME.
9611 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
9612 (MAINTAINERCLEANFILES): Split into pieces,
9613 one per related section. Add $(srcdir)/wrapper.in.
9615 2004-02-09 Paul Eggert <eggert@twinsun.com>
9617 * doc/autoconf.texi (Setting Output Variables): Emphasize that
9618 AC_SUBST provides no portable way to escape literal newlines.
9620 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9621 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9622 Darwin uses -lcrt2.o and there's little point to cataloging all
9623 the system variants. Partial fix reported by Andreas Waechter in:
9624 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
9625 for bug reported by Nelson H. F. Beebe in:
9626 http://mail.gnu.org/archive/html/bug-autoconf/2003-12/msg00090.html
9628 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
9630 * doc/autoconf.texi (AU_DEFUN): Fix English,
9631 suggested by Paul Eggert.
9632 * lib/autoconf/autoupdate.m4: Correct reference to
9633 acobsolete.m4, suggested by Alexandre Duret-Lutz.
9635 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
9637 * bin/autoupdate.in: Define __file__ so that warnings
9638 refer to the correct file.
9639 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
9640 the behavior of the third argument.
9641 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
9642 correctly the behavior of the third argument. Document
9643 what the three macros that AU_DEFUN defines do. Fix

9663 (AS_REQUIRE_SHELL_FN): Require shell functions when
9664 it is used.
9665 (_AS_LINENO_WORKS): Put around braces, we do not

9677 (AU_DEFUN): Honor the third parameter, create autoupdate
9678 macros with AU_DEFINE.
9679 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
9680 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

9699 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

9702 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
9704 2004-01-27 Gary V. Vaughan <gary@gnu.org>

9722 2004-01-27 Paul Eggert <eggert@twinsun.com>
9724 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
9725 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
9726 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
9727 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
9729 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
9730 bin/autoconf.in, config/Makefile.in, config/config.guess,
9731 config/config.sub, config/install-sh, config/mdate-sh,

9746 2004-01-26 Paul Eggert <eggert@twinsun.com>
9748 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9749 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9750 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9751 not <inttypes.h>. Problem reported by Tim Mooney in
9752 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9753 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9754 Likewise.
9756 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9757 otherwise "make check" fails because it forbids cmp (I guess
9758 because cmp treats files as binary on DOS-like systems).
9760 * tests/mktests.sh: Update copyright date to 2004, since some tests
9761 have changed in 2004.
9763 2004-01-23 Gary V. Vaughan <gary@gnu.org>

9766 non-truncating sed or gsed program in PATH.
9767 * tests/acprograms.at: Add it.
9768 * doc/autoconf.texi (Particular Programs): Document it.
9769 * NEWS: Updated.
9771 2004-01-15 Paul Eggert <eggert@twinsun.com>
9773 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9774 -std1 disables some useful extensions on Tru64. Problem reported
9775 by N. Lichtmaier in
9776 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
9778 2004-01-14 Paul Eggert <eggert@twinsun.com>
9780 * doc/autoconf.texi (Programming in M4sh): Document that
9781 AS_MKDIR_P succeeds if the destination is a symbolic link
9782 to an existing directory.
9783 (Limitations of Usual Tools): Note that mkdir -p might not
9784 succeed on symlinks to directories.
9786 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9788 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
9789 * bin/autoheader.in: Grammar fix in message.
9790 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
9791 Test for dir before calling mkdir -p. (trivial changes)
9793 2004-01-13 Eric Blake <ebb9@byu.net>
9795 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
9796 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
9798 2004-01-10 Jim Meyering <jim@meyering.net>
9800 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
9802 2004-01-09 Paul Eggert <eggert@twinsun.com>
9804 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9805 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9806 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9807 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9808 AC_COMPILE_IFELSE, since we now assume our caller invokes
9809 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9810 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9811 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9812 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9814 2004-01-07 Paul Eggert <eggert@twinsun.com>
9816 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9817 `"'...'"`, as it's confusing (and I suspect it may not work on
9818 some platforms). The code was incorrect anyway, as it assumed
9819 that \$ evaluated to itself in that context. Reported by
9820 Alexandre Duret-Lutz.
9822 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9824 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

9829 * doc/autoconf.texi (One Macro Call): Fix an incorrect
9830 example, and add more examples. Reported by Eric Sunshine.
9832 2004-01-05 Paul Eggert <eggert@twinsun.com>
9834 * doc/autoconf.texi (Limitations of Usual Tools):
9835 Remove warning against "rm -fr" introduced yesterday; it
9836 was a false alarm.
9838 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
9839 autoscan, autoupdate, ifnames): Don't use chmod -w.
9840 * lib/Makefile.am (autom4te.cfg): Likewise.
9841 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
9842 "chmod -w".

9845 Paolo Bonzini <bonzini@gnu.org>
9847 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
9848 by doing lineno substitution only on lines containing "$LINENO".
9850 2004-01-04 Paul Eggert <eggert@twinsun.com>
9852 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
9853 Use "rm -f" to remove conftest.sed, not plain "rm".
9854 Bug reported by David Relson in
9855 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9857 * Makefile.am (autom4te-update):
9858 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
9859 * Makefile.maint (my-distcheck, do-po-update): Likewise.
9860 * doc/autoconf.texi (Guidelines): Likewise.
9861 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

9866 * tests/Makefile.am (clean-local): Likewise.
9867 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
9868 srcdir): Likewise.
9869 * doc/autoconf.texi (Limitations of Usual Tools):
9870 Warn against "rm -fr".
9872 2004-01-03 Paul Eggert <eggert@twinsun.com>
9874 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9875 -c -o might not work. From a suggestion by Kevin Ryde.
9876 (C Compiler, Generating Sources, Limitations
9877 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9878 Don't put '-o' after non-options, as POSIX doesn't allow this.
9879 Mention that cc's name might be gcc or c89 or whatever.
9881 2004-01-04 Kevin Ryde <user42@zip.com.au>
9883 * doc/autoconf.texi: Add various further index entries.
9885 2003-12-29 Paul Eggert <eggert@twinsun.com>
9887 * bin/autoreconf.in (autoreconf_current_directory):
9888 Fix typo: mkdir without umask arg.
9890 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9892 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9893 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
9894 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
9895 explanation clearer.
9897 2003-12-24 Andreas Schwab <schwab@suse.de>

9904 * configure.ac: Test if sh -n works.
9905 * configure: Regenerate.
9906 * tests/atlocal.in: Store the result here.
9907 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
9908 tools.at, looking in atlocal's ac_cv_sh_n_works instead
9909 of explicitly testing.
9910 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
9911 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
9912 * tests/tools.at (Syntax of the shell scripts): Simplify
9913 using AT_CHECK_SHELL_SYNTAX.
9914 (Syntax of the Perl scripts): Remove definition of
9915 AT_CHECK_PERL_SYNTAX.
9917 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
9919 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
9920 stderr to /dev/null.
9921 * bin/autoconf.in: Regenerate.
9922 * bin/wrapper.in: Regenerate.

9926 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
9927 Extracted from AS_SHELL_SANITIZE.
9928 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
9929 macros.
9930 (AS_SHELL_SANITIZE): Move reinvocation code from
9931 _AS_LINENO_WORKS, use it to find out if shell
9932 functions work.
9933 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
9934 does not work.
9935 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
9936 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
9937 was called.

9952 2003-11-24 Akim Demaille <akim@epita.fr>
9954 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

9982 parameter of AU_DEFUN.
9983 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.

9987 the expanded body, consistently with other macros such as AC_USG.
9989 2003-11-17 Paul Eggert <eggert@twinsun.com>
9991 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes

9993 patch 3 reported by Eric Sunshine.
9995 2003-11-15 Kevin Ryde <user42@zip.com.au>
9997 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
9998 than $target since the latter is not usual, add guidelines on when to
9999 use or not use the system type.
10001 2003-11-12 Derek Price <derek@ximbiot.com>
10003 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
10004 typo misrepaired by an auto-spellcheck.
10006 2003-11-12 Akim Demaille <akim@epita.fr>

10009 --force-missing unless it actually supports it.
10010 From Debian #219336.

10023 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE
10024 so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,

10072 the current language is Fortran.
10074 2003-10-31 Akim Demaille <akim@epita.fr>
10076 * bin/autom4te.in (&freeze): Use a less likely warning separator
10077 than `\n\n', so that `\n\n\n' is valid in warnings.
10078 Reported by Steve Huston.
10080 2003-10-28 Akim Demaille <akim@epita.fr>

10164 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
10166 2003-10-10 Andreas Schwab <schwab@suse.de>
10168 * bin/autoheader.in: Avoid empty first line in --version and

10180 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10181 -mGLOB_options_string stuff for Intel ifc, which can cause
10182 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
10183 pattern-matching instead of grep.
10185 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>

10203 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
10205 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10206 cache variable instead of $G77 to decide whether to include -O2,
10207 since $G77 is specific to Fortran 77.
10209 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10211 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

10216 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
10217 arguments so that it can be used with syntax identical to
10218 AC_PROG_F77, and so that we can more easily decide to
10219 remove/deprecate the DIALECT optional argument in the future if it
10220 proves troublesome.
10221 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10222 non-freeform-supporting compilers. Document freeform flags.
10224 2003-10-03 Akim Demaille <akim@epita.fr>
10226 * configure.ac: Look for emacs, not macs.
10227 Reported by Eric Sunshine.
10229 2003-10-03 Akim Demaille <akim@epita.fr>
10231 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
10232 * bin/autoreconf.in (autoreconf_current_directory): Create the
10233 AUX_DIR if needed, for sake of automake --add-missing etc.
10234 Suggested by Alexandre Duret-Lutz.
10236 2003-10-03 Akim Demaille <akim@epita.fr>
10238 * configure.ac: Quotation and formatting changes.

10272 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
10273 have been created when invoking the compiler.

10286 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10287 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10288 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10289 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10291 2003-09-26 Akim Demaille <akim@epita.fr>
10293 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10294 directory for AC_CONFIG_COMMANDS' first argument exists.
10295 This makes valid the invocation of _AC_SRCPATH that follows.
10296 Reported by Eric Sunshine.
10297 * doc/autoconf.texi (Configuration Commands): Adjust.
10299 2003-09-26 Akim Demaille <akim@epita.fr>
10301 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
10302 Reported by Ralf Corsepius.
10304 2003-09-26 Akim Demaille <akim@epita.fr>
10306 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
10307 arguments.

10318 2003-09-26 Akim Demaille <akim@epita.fr>
10320 The test suite are sometimes assigning timings incorrectly.
10321 Reported by Henk Krus.
10322 Diagnosed by Nicolas Joly.
10324 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10325 AT_help_all.
10326 Instead of making AT_help a sequence of assignments to grow
10327 $at_help_all, just make AT_help_all be the growing contents of
10328 $at_help_all, and make a single assignment in...
10329 (AT_INIT): here.
10330 (at_times_skip): Flip the meaning and rename as...
10331 (at_times_p): this.
10332 (AT_INIT): When summarizing the test that ran, remove
10333 $at_times_file after use, and check it is present before trying to
10334 use it.
10336 2003-09-25 Akim Demaille <akim@epita.fr>
10338 Version 2.57d.
10340 * bin/Makefile.am (edit): Handle '@configure_input@'.
10341 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
10342 (ifnames): chmod -w.
10343 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10344 executables, not bin/ executables! Otherwise all the magic needed
10345 to find non installed files is turned off. This caused a failure
10346 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10347 as found in its environment (sent by tests/autoreconf): pointing
10348 to bin/autom4te that could not find its files.
10349 * tests/mktests.sh: Force the replacement of generated files, for
10350 the sake of "mv" program that are interactive when overwriting a
10351 -w file.
10352 * config/install-sh: Upgrade from CVS Automake.
10354 2003-09-23 Paul Eggert <eggert@twinsun.com>

10359 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10360 Paul Eggert <eggert@twinsun.com>
10362 Trivial change to support GCC's configuration procedure.

10364 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
10365 about inconsistency if the preprocessor is set to give errors for
10366 any warning.

10395 2003-09-10 Akim Demaille <akim@epita.fr>
10397 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
10398 willing to edit the output files.
10400 2003-09-10 Akim Demaille <akim@epita.fr>
10402 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10403 and AC_FC_FREEFORM.
10404 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10405 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
10407 2003-09-09 Akim Demaille <akim@epita.fr>

10420 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
10421 Improve the accuracy of the wording about obsolescence.
10422 From a suggestion by Ian Lance Taylor in

10425 2003-09-05 Paul Eggert <eggert@twinsun.com>
10427 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
10428 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
10430 2003-09-04 Akim Demaille <akim@epita.fr>
10432 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
10433 AC_FUNC_WAIT3.
10435 2003-09-04 Akim Demaille <akim@epita.fr>
10437 * bin/autom4te.in: Use &fatal where more appropriate than &error.
10438 (freeze): When exiting, use $exit_code.
10439 * lib/autoconf/fortran.m4: Comment changes.
10441 2003-09-04 Akim Demaille <akim@epita.fr>
10443 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10445 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10447 Add support for newer Fortran dialects. The F77 interface is
10448 unchanged, and continues to support Fortran 77. New FC macros
10449 correspond to all the old F77 macros, with output variables FC,
10450 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10451 available dialect, but older dialects can be specified. There are
10452 new macros AC_FC_SRCEXT to set the source extension, and
10453 AC_FC_FREEFORM to accept free-form source files.
10455 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
10456 New macros.
10457 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
10458 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
10459 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
10460 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

10472 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
10473 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
10474 Rewrite in terms of the above.
10475 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
10476 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

10478 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
10480 2003-09-02 Paul Eggert <eggert@twinsun.com>
10482 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
10483 Document problems with timestamp resolution that 'make', 'cp -p', and

10489 output, so that we can track spurious m4sugar output.
10490 * tests/local.at: Require 2.57.
10491 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10492 are defaulted by AT_CHECK anyway.
10493 Use AT_CHECK_AUTOM4TE.
10494 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
10495 missing dnl.
10497 2003-08-27 Akim Demaille <akim@epita.fr>
10499 * bin/autoheader.in: Issue the "Using auxiliary..." message only
10500 when -Wobsolete is set.

10556 2003-08-22 Akim Demaille <akim@epita.fr>
10558 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
10559 * bin/autom4te.in: Adjust.
10561 2003-08-21 Akim Demaille <akim@epita.fr>
10563 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
10564 (&verbose): Remove.
10565 (&getopt): Adjust the note and verb channels, depending upon
10566 --verbose.
10567 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
10568 * bin/autoupdate.in: Adjust.
10569 Use &verb, not &verbose.
10571 2003-08-21 Akim Demaille <akim@epita.fr>
10573 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10574 &parse_WARNINGS.
10575 ($help): Use Autom4te::ChannelDefs::usage.
10576 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10577 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10579 2003-08-21 Akim Demaille <akim@epita.fr>
10581 First stab at preserving warnings between calls to autom4te,
10582 including when the cache is used.
10584 There are still several issues: (i) there are too many runs of m4
10585 (one for include, one for warnings, and some more), (ii) warnings
10586 spreading on several lines are not handled gracefully, (iii) the
10587 code meant to have the call stack display for errors does not work
10588 (its handling should move from m4 to autom4te).
10590 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10591 Use them.
10592 (@preselect): Add m4_warn.
10593 ($exit_status): Remove, use $exit_code.
10594 ($help): Use Autom4te::ChannelDefs::usage.
10595 (&handle_m4): No longer define the m4_warnings.
10596 At each run, extract and report the warnings.
10597 Always cache the result, including if the exit status is on
10598 failure, since if nothing changes, we should result in the same
10599 failure, hence we can use the cache.
10600 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10601 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10602 Remove.
10603 (m4_warn): Redefine as a do-nothing: it is its invocation that
10604 matters, as warnings are now reported via traces.
10605 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10606 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10607 the latter reveals calls to the former.
10609 Adjust the tests.
10611 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10613 2003-08-21 Akim Demaille <akim@epita.fr>
10615 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
10616 Use them.
10618 2003-08-21 Akim Demaille <akim@epita.fr>
10620 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
10621 forward order.
10622 * lib/Autom4te/ChannelDefs.pm: Doc typos.
10623 (&parse_warnings): Accept a list of warning requests.
10624 (&usage): Return a string, not a side effect.
10625 (cross): New warning category.
10627 2003-08-21 Akim Demaille <akim@epita.fr>
10629 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
10630 (&require_configure_ac): Accept an optional directory argument.
10631 ($configure_ac): Remove.
10632 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10633 (&catfile): Remove.
10634 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10635 * bin/autoscan.in: Adjust.
10637 2003-08-20 Akim Demaille <akim@epita.fr>
10639 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
10640 Reported by Alexandre Duret-Lutz.
10642 2003-08-20 Akim Demaille <akim@epita.fr>
10644 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10645 * bin/autom4te: Adjust.
10646 In particular, be Autoconf tools are really silent when properly
10647 working, bind the verbosity of the 'note' channel to $verbose.
10648 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10649 (&xsystem, &contents): Remove, since they are exported by...
10650 * lib/Autom4te/FileUtils.pm: this.
10651 More perldoc.
10652 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10653 * lib/Autom4te/FileUtils.pm: here.
10655 2003-08-20 Akim Demaille <akim@epita.fr>
10657 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
10658 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
10659 from CVS Automake.
10661 2003-08-20 Akim Demaille <akim@epita.fr>
10663 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
10664 (autom4te-update): New.
10665 * Makefile.cfg (update): Bind autom4te-update.
10667 2003-08-19 Derek Price <derek@ximbiot.com>
10669 * lib/autotest/general.m4: Comment various HELP_* diversions.
10670 (PARSE_ARGS_BEGIN): New section for option parsing related
10671 initialization.

10679 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
10681 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
10683 * lib/autom4te.in (Automake-preselections): Preselect
10684 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
10685 and m4_sinclude.
10687 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
10689 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
10690 (Autoconf-without-aclocal-m4): ... this new language.
10691 * doc/autoconf.texi (autom4te Invocation): Mention
10692 Autoconf-without-aclocal-m4.
10694 2003-08-18 Derek Price <derek@ximbiot.com>
10696 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
10697 RUN-IF-PASS optional arguments.

10706 STDOUT & STDERR arguments.
10708 2003-08-14 Derek Price <derek@ximbiot.com>
10710 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
10711 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
10712 shorter column three. Add DESCRIPTION to log file content.
10714 2003-08-13 Derek Price <derek@ximbiot.com>
10716 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
10717 output.
10719 2003-08-12 Derek Price <derek@ximbiot.com>
10721 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
10722 (AT_CHECK_NOESCAPE): Move core functionality to...
10723 (_AT_CHECK): ...this new macro.
10725 2003-08-07 Derek Price <derek@ximbiot.com>
10727 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
10728 (AT_CHECK_NOESCAPE): ...to this new macro.
10730 2003-07-31 Paul Eggert <eggert@twinsun.com>
10732 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
10733 in Bash 2.01. Problem reported by Brian Gough in
10734 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
10736 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
10738 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
10739 -lcrt1.o, for OS X. (trivial change)
10741 2003-07-07 Paul Eggert <eggert@twinsun.com>
10743 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
10744 inside '#ifndef __cplusplus'. Problem reported by
10745 Bob Friesenhahn.
10747 2003-07-06 Bill Clarke <llib@computer.org>
10749 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10750 'long', not 'int', for benefit of Sun's recent C++ compilers
10751 (trivial change). See:
10752 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
10753 (This really should be 'intptr_t', not 'long', but that would
10754 take more work.)
10756 2003-06-25 Akim Demaille <akim@epita.fr>
10758 * lib/Makefile.am (autom4te.cfg): Make it read only.
10759 Depend on Makefile since it contains substitutions.
10760 From Paolo Bonzini.
10761 * lib/autom4te.in (args): Add local.at? for Autotest args.
10762 This change was made on autom4te.cfg which is generated.
10763 Reported by Raja R. Harinath.
10765 2003-06-25 Akim Demaille <akim@epita.fr>
10767 * doc/autoconf.texi (Header Portability): sys/mount.h.
10768 From Gareth McCaughan.
10770 2003-06-23 Akim Demaille <akim@epita.fr>
10772 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10773 not all of them. This fixes 1. the fact that when testing
10774 Autoconf there are many many config.log, 2. the incorrect use of
10775 top_srcdir to find config.log.
10776 Don't mix the detailed output of failed test with the summary of
10777 failures. Rather, append detailed log afterwards.
10779 2003-06-23 Akim Demaille <akim@epita.fr>
10781 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
10782 always run: output config.log on $at_group_log.
10784 2003-06-23 Akim Demaille <akim@epita.fr>
10786 * tests/torture.at (#define header templates): Don't use quotes in
10787 C++ comments as it puzzles Emacs' sh font-lock-mode.
10789 2003-06-23 Akim Demaille <akim@epita.fr>
10791 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
10792 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
10793 * tests/atspecific.m4: Rename as...
10794 * tests/local.at: This.
10795 * tests/suite.at: Move the globals into...
10796 * tests/local.at: here.
10797 * tests/Makefile.am: Adjust.
10798 * doc/autoconf.texi (testsuite Scripts): Adjust.
10800 2003-06-21 Kevin Ryde <user42@zip.com.au>
10802 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
10803 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
10804 ensuring we add -std1 for full-ANSI.
10806 * doc/autoconf.texi (hdrindex): New macro.
10807 Add index entries for portability of various standard header files.
10809 2003-06-20 Akim Demaille <akim@epita.fr>
10811 * configure.ac: Bump to 2.57b.
10813 2003-06-20 Akim Demaille <akim@epita.fr>
10815 Version 2.57a.
10817 2003-06-20 Akim Demaille <akim@epita.fr>
10819 * bin/autom4te.in: Don't rely on $HOME being defined.
10820 Reported by Marc Espie as PR/233.
10822 2003-06-20 Akim Demaille <akim@epita.fr>
10824 * lib/autotest/general.m4: Use at_times_file only if used.
10825 From Nicolas Joly.
10827 2003-06-20 Akim Demaille <akim@epita.fr>
10829 * config/config.guess, config/config.sub, config/elisp-comp,
10830 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
10831 Update from masters.
10833 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
10835 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
10836 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
10837 (TEST_SCRIPT): New diversion.
10838 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
10839 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
10840 (AT_INIT): Support for expected failures.
10842 2003-06-02 Akim Demaille <akim@epita.fr>
10844 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
10845 changes.
10846 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
10847 Autoconf nor Automake.
10848 (&contents): New, from Automake.
10849 PODify.
10851 2003-05-28 Paul Eggert <eggert@twinsun.com>
10853 * NEWS, doc/autoconf.texi (Particular Functions),
10854 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
10855 is the inverse of localtime.
10857 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
10859 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10860 (handle_exec_errors): New function. Work around $! being
10861 altered by WEXITSTATUS.
10862 (xqx, xsystem): Use handle_exec_errors.
10864 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10866 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10867 Do not call `_exit()', simply modify `$?'.
10868 (xsystem): Reset $! before running system, and check it afterward.
10869 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10870 63 for version mismatches.
10872 2003-05-23 Akim Demaille <akim@epita.fr>
10874 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10875 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10876 the middle of a line).
10877 * lib/m4sugar/m4sugar.m4: Likewise.
10878 Remove useless spaces in comments.
10880 2003-05-23 Akim Demaille <akim@epita.fr>
10882 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10883 exit 63, so that we (or Automake's "missing") can tell the
10884 difference with a plain failure.
10885 * doc/autoconf.texi (Notices): Adjust.
10887 2003-05-23 Akim Demaille <akim@epita.fr>
10889 * Makefile.am, bin/Makefile.am, config/Makefile.am,
10890 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
10891 White spaces cleanup.
10893 2003-05-22 Jim Meyering <jim@meyering.net>
10894 Paul Eggert <eggert@twinsun.com>
10896 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10897 Remove `#include <stdlib.h>' from the list; we should never
10898 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10899 resulting namespace pollution would cause other tests to fail.
10900 Configure scripts run with some older versions of g++ and HP's
10901 aCC would fail due to such an #include. Problems reported by
10902 Matthew Mueller in <http://bugs.debian.org/120704> and by
10903 Keith Bostic in
10904 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10905 In the test, use the test declaration before including <stdlib.h>,
10906 as that's closer to how it'll be used.
10908 2003-05-23 Akim Demaille <akim@epita.fr>
10910 * doc/autoconf.texi (Header Portability): ucred.h.
10911 From Ian Redfern.
10913 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10915 Overhaul Autotest's logging: generate separate log files
10916 in testsuite.dir/NNN/testsuite.log, and append them to
10917 testsuite.log instead of re-running the test verbosely.
10919 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10920 file descriptor, write 0 to at_status_file instead of setting
10921 at_status=0, initialize some new variables (at_status_file,
10922 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10923 to rerun the tests, instead append the at_group_log to the
10924 at_suite_log when a test fails.
10925 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10926 with the AS_MESSAGE_LOG_FD redirected to stdout.
10927 (AT_CLEANUP): save the output status in $at_status_file
10928 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10929 its original place.
10930 (AT_CHECK): since tests are run with a redirected stdout,
10931 and used to be re-run in verbose mode, turn some $at_verbose
10932 into echo, and don't redirect the output of testing stdout
10933 and stderr.
10935 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10936 the name of the debugging directory and information about
10937 its contents.
10939 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10941 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
10942 parameter.
10944 2003-05-22 Akim Demaille <akim@epita.fr>

10965 Suggested by Jim Meyering.
10967 2003-05-22 Akim Demaille <akim@epita.fr>
10969 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed

10971 Reported by Jim Meyering.
10973 2003-05-22 Akim Demaille <akim@epita.fr>
10975 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

10999 * ChangeLog, ChangeLog.2, THANKS, lib/m4sugar/m4sugar.m4:
11000 Remove non-ASCII characters.
11002 2003-05-18 Paolo Bonzini <bonzini@gnu.org>
11004 * tests/semantics.at (AC_SEARCH_LIBS): New test.
11005 * tests/semantics.at (AC_CHECK_HEADERS_OLD,
11006 AC_CHECK_HEADERS_NEW): New tests.
11008 2003-05-17 Akim Demaille <akim@epita.fr>
11010 * lib/autoconf/functions.m4: Use the default includes so that
11011 memcmp be declared before being tested.
11012 Reported by Sander Niemeijer.
11013 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

11056 2003-05-06 Akim Demaille <akim@epita.fr>
11058 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
11059 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11060 by aclocal.m4 is changed it might require the importing of another
11061 m4 extension file, i.e., aclocal must be run.
11063 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
11064 (&parse_args): Use --force with aclocal if required and supported.
11065 (&autoreconf_current_directory): Use &run_aclocal.

11078 2003-04-29 Derek Price <derek@ximbiot.com>
11080 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
11081 seperator with m4_append_uniq(). It doesn't work.
11082 (AT_CLEANUP): Add `;' to end of at_help_all.
11083 (AT_INIT): Allow --keywords to be specified more than once. When
11084 grepping $at_help_all for keywords, use the field and keyword
11085 seperators to ensure a complete keyword match. Alter at_prev handling
11086 to support the new --keywords behavior.
11088 2003-04-27 Karl Berry <karl@freefriends.org>
11090 * doc/autoconf.texi: Make the dir entries in the autoconf manual
11091 align better with others. I also made some of the individual
11092 entries on one line, for brevity and to make it easier for me to
11093 sort my dir-example file in the Texinfo distribution :).

11134 Use them.
11135 * doc/Makefile.am (CLEANFILES): Adjust.

11138 2003-03-31 Derek Price <derek@ximbiot.com>

11164 * tests/torture.at (Configuring subdirectories): Require aclocal
11165 1.4, otherwise the test fails, as it does support configure.ac.
11166 This fixes the "test 40 failed" bug reports.
11168 2003-03-28 Akim Demaille <akim@epita.fr>
11170 * doc/autoconf.texi (C Compiler): `#line' portability.

11176 layout in order to allow scripting around test groups.
11178 2003-03-27 Derek Price <derek@ximbiot.com>
11180 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
11181 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
11182 use new diversions in preparation for accepting new arguments and

11196 2003-03-26 Derek Price <derek@ximbiot.com>
11198 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
11199 sense. Verbosify the diversion definitions comment.
11201 2003-03-26 Derek Price <derek@ximbiot.com>
11203 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
11204 AS_PREPARE.

11225 file name for the m4 program, when it has an "exe" file extension.
11226 DJGPP's error messages include the error code in brackets -
11227 remove the error code during normalization.

11237 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
11238 Tru64 make in the "target lookup" section.
11239 (Automake): Automake 1.5+ no longer requires special tools to be
11240 present on the developer's host.
11242 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
11244 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
11245 to a shell that can handle redirection or quoting correctly.

11257 to cope with DOS-style absolute paths, when constructing
11258 ${ac_make}.
11260 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
11261 When constructing paths with IFS=:, quote the path. If we're
11262 constructing a DOS-style absolute path, we don't want to split it
11263 on the colon.
11265 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
11266 in description.
11268 2003-02-25 Pavel Roskin <proski@gnu.org>
11270 * bin/autoheader.in: Add missing newline when printing
11271 suggestion how change AC_DEFINE call.
11273 2003-02-24 Paul Eggert <eggert@twinsun.com>
11275 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix typo in
11276 2002-09-01 patch by replacing "test -n" with "test -z".
11277 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
11278 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
11280 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
11281 to fix a mismatch between example and discussion.
11283 2003-02-24 Kevin Ryde <user42@zip.com.au>
11285 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
11286 format starting with "-".
11288 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
11290 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
11291 is not portable inside Makefile.
11293 2003-02-20 Akim Demaille <akim@epita.fr>
11295 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
11296 compiler says yeah, but preproc says nope, compiler is right.
11297 Conversely, prompt the reader to send a bug report to the
11298 maintainers of the package, not of Autoconf.
11300 2003-02-20 Klee Dienes <kdienes@apple.com>
11302 * bin/autoreconf.in (autoreconf_current_directory): Properly
11303 handle an empty aclocal.m4.

11313 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11314 innocuous variant befor including <limits.h> or <assert.h>. This
11315 works around a bug reported by Albert Chin: HP-UX 11i
11316 (and earlier versions) have a <limits.h> that declares
11317 gettimeofday and many other functions.
11319 2002-12-03 Paul Eggert <eggert@twinsun.com>
11321 Version 2.57.
11323 * NEWS, configure.ac: Update version.
11325 * doc/fdl.texi: Upgrade to FDL version 1.2.
11327 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11328 nontrivially in main's body, so that f's external declaration is
11329 not optimized away in AIX. This should fix the bug reported by
11330 Martin Frydl in
11331 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11333 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11334 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11335 defined, to support freestanding compilers. This should fix the
11336 bug reported by Momchil Velkov in
11337 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11339 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11340 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
11341 obsolete AC_CHECK_TYPE. The missing empty arg was reported
11342 by Simon Josefsson in
11343 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
11345 * Makefile.maint (www-gnu): New macro.
11346 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
11347 the location has moved.
11349 2002-12-02 Martin Frydl <martin@systinet.com>
11351 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
11352 \(.*\) match is too long and there is something more to be checked.
11353 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
11355 2002-11-15 Akim Demaille <akim@epita.fr>
11357 Version 2.56.
11359 * config/install-sh: chmod +x.
11360 From Paul Eggert.
11361 * config/move-if-change: Indenting changes.
11362 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
11363 * configure.ac (AM_INIT_AUTOMAKE): here.
11364 Require 1.7.1.
11366 2002-11-14 Akim Demaille <akim@epita.fr>
11368 Version 2.55.
11370 * config/config.guess, config/config.sub, config/install-sh:
11371 Update from masters.
11373 2002-11-14 Akim Demaille <akim@epita.fr>
11375 * Makefile.maint: Sync with Bison, i.e.:
11376 (po-check): Scan .l and .y files instead of the
11377 .c and the .h files that they generate. This fixes the bug
11378 reported by Tim Van Holder in:
11379 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11380 Look for N_ as well as for _. Try to avoid matching #define for
11381 N_ and _.
11382 From Paul Eggert.
11384 2002-11-14 Akim Demaille <akim@epita.fr>
11386 * doc/autoconf.texi (C Compiler): Compiling several files at once.
11387 From Paul Eggert and Albert Chin-A-Young.
11389 2002-11-14 Akim Demaille <akim@epita.fr>
11391 * doc/autoconf.texi (C Compiler): Solitary backslashes.
11392 From Paul Eggert and Albert Chin-A-Young.
11394 2002-11-14 Kevin Ryde <user42@zip.com.au>
11396 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11397 than assigning in main, to avoid HP cc +O3 optimizing it away.
11399 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11401 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11402 option. Process --recheck after parsing all options. Pass -q
11403 option to configure on --recheck.
11404 (AC_OUTPUT): Pass -q from configure to config.status.
11405 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11406 arguments to record.
11407 * doc/autoconf.texi (config.status Invocation): Document
11408 config.status -q option.
11410 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11412 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11413 Makefile.in if Makefile.am exists.
11414 (output): Strip `.am' from Makefiles. Don't
11415 output AC_CONFIG_FILES if no Makefiles were found.
11417 2002-11-07 Akim Demaille <akim@epita.fr>
11419 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.

11422 (local_updates): New.
11424 2002-11-06 Akim Demaille <akim@epita.fr>
11426 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
11427 declaration in extern "C" too.
11428 Reported by Roberto Bagnara.
11430 2002-11-06 Akim Demaille <akim@epita.fr>
11432 * tests/torture.at (Configuring subdirectories): Don't use grep
11433 -w.
11434 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
11435 Reported by Ezra Peisach.
11437 2002-11-05 Akim Demaille <akim@epita.fr>
11439 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11440 Remove.
11441 We _have_ to stop using the old compatibility scheme that tried to
11442 avoid useless backslashes because Libtool 1.4.3 contains a
11443 AC_DEFINE([error_t], [int],
11444 [Define to a type to use for \`error_t' if it is not
11445 otherwise available.])
11446 We _have_ to quote the single quote and backslashes with \. The
11447 old compatibility scheme saw that ` was backslashed, and therefore
11448 did not quote the single quote. Hence before this patch, Autoconf
11449 was not compatible with Libtool.
11451 2002-11-04 Paul Eggert <eggert@twinsun.com>
11453 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
11454 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
11455 LC_NAME, LC_PAPER, LC_TELEPHONE.
11456 * doc/autoconf.texi (Special Shell Variables): Mention those vars.
11458 2002-11-04 Akim Demaille <akim@epita.fr>
11460 Version 2.54c.
11462 * Makefile.maint (update, cvs-update, po-update, do-po-update):
11463 New.
11464 * config/texinfo.tex: Update.
11466 2002-11-03 Akim Demaille <akim@epita.fr>
11468 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
11469 from...
11470 (&autoreconf): here.
11471 ($help, $make, &parse_args, &autoreconf_current_directory):
11472 Support -m/--make.
11473 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11475 2002-10-31 Bruno Haible <bruno@clisp.org>
11477 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.
11478 Change name of cache variable to ac_cv_func_malloc_0_nonnull.
11479 (AC_FUNC_MALLOC): Change description of HAVE_MALLOC macro.
11480 (_AC_FUNC_REALLOC_IF): Change message. Change name of cache variable
11481 to ac_cv_func_realloc_0_nonnull.
11482 (AC_FUNC_REALLOC): Change description of HAVE_REALLOC macro.
11484 2002-10-31 Akim Demaille <akim@epita.fr>
11486 The test suite was no longer checking for trailing envvars and files.
11488 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.

11781 2002-10-22 Akim Demaille <akim@epita.fr>
11783 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

11794 (_AS_QUOTE): Accept $2 as list of characters to quote.
11795 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
11796 Quote for Perl, not sh.
11797 * bin/autoheader.in: When $debug, report the file which is

11800 `@', to tickle Perl's lists.

11836 2002-10-16 Akim Demaille <akim@epita.fr>
11838 Because of caching, some files that no longer exist and are no
11839 longer required can still cause errors.
11840 Reported by Alexandre Duret-Lutz.
11842 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
11843 to frozen files in @ARGV, as @ARGV must remain being a list of

11845 (&files_to_options): New function.
11846 (&freeze): Use &error.
11847 (&up_to_date): If a file that was included according to the cache
11848 is no longer there, then the output is out dated.

11850 --force is given.
11851 * tests/tools.at (autom4te cache): New.
11853 2002-10-16 Akim Demaille <akim@epita.fr>
11855 * bin/autoconf.as: Kill dead options.
11856 * bin/autoupdate.in (&parse_args): Kill old options.
11857 * bin/autoreconf.in (&parse_args): Remove dead options.
11858 Factor some code.
11859 (&autoreconf): Report the directories we enter *and leave*, so
11860 that error messages can be easily located, and use GNU Make
11861 format, so that Emacs' compile mode understands us.
11862 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
11863 if some file was changed instead of `print'.
11864 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
11865 (&parse_args): Remove the dead options.
11866 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new

11878 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

11890 2002-10-11 Akim Demaille <akim@epita.fr>
11892 * tests/torture.at (AC_ARG_VAR): Have configure report the value
11893 of `precious'.
11895 2002-10-11 Akim Demaille <akim@epita.fr>
11897 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
11898 file name to enable parallel executions.
11899 From Sam Varshavchik.
11901 2002-10-08 Akim Demaille <akim@epita.fr>
11903 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11904 aclocal invocation, as Gettext macros might not be visible to
11905 aclocal.
11906 Instead of blindly running autopoint, scan configure.ac (not the
11907 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11908 Reported by Paul D. Smith.
11910 2002-10-08 Paul Eggert <eggert@twinsun.com>
11912 Work around problems found when POSIXLY_CORRECT=1 is set.
11913 None of this seems to have anything to do with POSIX, really,
11914 but it's how Perl getopt works.
11915 * bin/autom4te.in (parse_args): Configure GetOpt with
11916 "permute", too.
11917 * doc/autoconf.texi (Invoking autom4te):
11918 --warning -> --warnings.
11919 * lib/autom4te.in: --warning -> --warnings.
11921 2002-09-28 Akim Demaille <akim@epita.fr>

11938 2002-09-28 Akim Demaille <akim@epita.fr>
11940 * tests/torture.at (Configuring subdirectories): Be robust to
11941 users who use config.site to require for a cache: in this case,
11942 the two last configure runs, using two different sets of
11943 arguments, trigger a legitimate error.
11945 2002-09-28 Akim Demaille <akim@epita.fr>
11947 * tests/m4sh.at (Functions Support, Functions and return Support):
11948 New.

11955 (autom4te): Specify that the sources are in the $srcdir.
11956 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11958 2002-09-28 Akim Demaille <akim@epita.fr>
11960 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
11961 (tm_zone): Move their rules to...
11962 * lib/autoconf/types.m4: here, using AN_ macros.
11963 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11964 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11965 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
11966 * lib/autoconf/programs.m4: here.
11967 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)

11978 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11979 (.m4.m4f): Don't pass --prepend-include, since that's done by
11980 tests/autom4te itself.
11981 * lib/autoscan/Makefile.am: Include freeze.mk.
11982 (autoscan.list): New target --this file is no longer a source.

11993 2002-09-28 Akim Demaille <akim@epita.fr>
11995 * lib/autoscan/functions, lib/autoscan/headers,
11996 * lib/autoscan/identifiers, lib/autoscan/makevars,
11997 * lib/autoscan/programs: Merge into...
11998 * lib/autoscan/autoscan.list: this.
11999 * bin/autoscan.in (&init_tables): Adjust.
12001 2002-09-28 Akim Demaille <akim@epita.fr>
12003 * lib/autoscan/functions, lib/autoscan/headers,
12004 * lib/autoscan/identifiers, lib/autoscan/makevars,
12005 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
12006 `functions' line is now prefixed with `function:'.
12007 * bin/autoscan.in (&init_tables): Adjust.
12009 2002-09-28 Akim Demaille <akim@epita.fr>
12011 From now on, autoscan files must always map a macro name to a
12012 word: there is no `default' macro for autoscan.
12014 * bin/autoscan.in (&init_tables): Reject entries with no macro at
12015 all.
12016 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
12017 explicit.
12019 2002-09-28 Akim Demaille <akim@epita.fr>
12021 * bin/autoscan.in (%c_keywords): Remove.
12022 (&used): Keep only track of the words we might be interested in.
12023 (&output_kind): It is no longer needed to look for non active
12024 checks.
12026 2002-09-27 Akim Demaille <akim@epita.fr>
12028 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
12029 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
12030 * lib/autoscan/functions: Adjust.
12031 * doc/autoconf.texi (Particular Functions): Adjust.
12033 2002-09-27 Akim Demaille <akim@epita.fr>
12035 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
12036 from /tmp.
12037 Thanks to Bill Moseley and Paul Eggert.
12038 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
12039 the tmpdir must be created.
12040 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp

12045 * bin/autoscan.in: Improve the comments.
12046 (&parse_args): Drop obsolete undocumented options.

12051 2002-09-26 Akim Demaille <akim@epita.fr>
12053 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
12054 Reported by Ralf Corsepius.
12055 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12057 2002-09-26 Akim Demaille <akim@epita.fr>
12059 Single suffix rules and seperated dependencies are not portable.

12063 Separated Dependencies'.
12064 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12065 (ifnames, autoscan, autom4te): Un-factor into several rules.
12067 2002-09-25 Paul Eggert <eggert@twinsun.com>
12069 * BUGS (Interoperability bugs): New section. Mention libtool
12070 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12072 2002-09-24 Paul Eggert <eggert@twinsun.com>
12074 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12075 make handles suffix-rules differently from GNU make.
12077 * bin/Makefile.am (SUFFIXES, .in): Remove.
12078 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12079 Move the body of the old .in rule here.
12081 2002-09-16 Akim Demaille <akim@epita.fr>
12083 i960 compilers create `b.out' files by default.
12084 Reported by Ralf Corsepius.
12086 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12087 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12089 2002-09-13 Paul Eggert <eggert@twinsun.com>
12091 * doc/autoconf.texi (Particular Headers): Remove obsolete
12092 reference to `struct timezone' in the description of
12093 AC_HEADER_TIME.
12095 2002-09-13 Akim Demaille <akim@epita.fr>
12097 Version 2.54.
12099 * config/config.sub, config/config.guess: Update.
12100 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12101 * Makefile.am: Adjust.
12103 2002-09-13 Akim Demaille <akim@epita.fr>
12105 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12106 reading config.log when the compiler is rejected.
12107 Suggested by Guido Draheim.
12109 2002-09-13 Akim Demaille <akim@epita.fr>
12111 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12112 (chdir_init) might hang when stat'ing mounted directories.
12113 Reported by Vance Shipley.
12115 2002-09-12 Akim Demaille <akim@epita.fr>
12117 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12118 the lists.
12120 2002-09-12 Akim Demaille <akim@epita.fr>
12122 * doc/autoconf.texi (Defining Symbols): Present two different
12123 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12124 difference between 1 argument calls, and 2-3 argument calls.
12126 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12128 * doc/autoconf.texi: Review grammar and punctuation.
12130 2002-09-11 Paul Eggert <eggert@twinsun.com>
12132 * doc/autoconf.texi: Fix minor formatting, spelling, and
12133 grammatical typos.
12134 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12135 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12136 is obsolescent.
12138 2002-09-11 Akim Demaille <akim@epita.fr>
12140 * doc/autoconf.texi (Questions): Rename as...
12141 (FAQ): this.
12142 (Defining Directories): New.
12144 2002-09-09 Akim Demaille <akim@epita.fr>
12146 * doc/autoconf.texi (Making testsuite Scripts): Update.
12147 Suggested by Nishio Futoshi.
12149 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12151 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12152 plain `@' is wanted.
12154 2002-09-09 Akim Demaille <akim@epita.fr>
12156 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12157 `duplicates', since the algorithm was too naive and could keep
12158 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12159 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12160 Reported by Ralf Corsepius.
12161 * tests/torture.at (Configuring subdirectories): Exercise these
12162 cases.
12164 2002-09-09 Akim Demaille <akim@epita.fr>
12166 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12167 looking for a replacement file.
12168 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12169 directory is relative.
12170 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12171 directory definition.
12172 Reported by Andreas Schwab and Jim Meyering.
12174 2002-09-06 Akim Demaille <akim@epita.fr>
12176 * doc/autoconf.texi (Setting Output Variables): Clarify what
12177 precious variables are.
12178 Suggested by Pontus Skoeld.
12180 2002-09-05 Akim Demaille <akim@epita.fr>
12182 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12183 (ifnames, autoscan, autom4te): Since we don't only depend on
12184 configure.ac variables (such as VERSION etc.), but also on prefix
12185 and so forth, depend on Makefile, not configure.ac.
12186 Reported by Alexandre Duret-Lutz.
12187 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12189 2002-09-05 Kevin Ryde <user42@zip.com.au>
12191 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12192 doesn't seem to be confined to ia64, just say "some versions".
12194 2002-09-04 Akim Demaille <akim@epita.fr>
12196 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12197 Automake 1.6c.
12198 * Makefile.am (maintainer-clean-local): Remove.
12199 (MAINTAINERCLEANFILES): Remove COPYING.
12201 2002-09-03 Paul Eggert <eggert@twinsun.com>
12203 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12204 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12205 Brinkmann.
12207 2002-09-03 Akim Demaille <akim@epita.fr>
12209 * configure.ac: Bump to 2.53d.
12210 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12211 as of today, on Automake's team suggestion.
12213 2002-09-03 Akim Demaille <akim@epita.fr>
12215 Version 2.53c.
12217 2002-09-02 Akim Demaille <akim@epita.fr>
12219 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12220 SITE_MACRO_DIR.
12221 * configure.ac: Disable SITE_MACRO_DIR.
12223 2002-09-02 Jim Meyering <meyering@lucent.com>
12225 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12226 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12227 Also, tweak grammar: s/make sure to/be sure to/.
12229 2002-09-02 Paul Eggert <eggert@twinsun.com>
12231 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12232 directory names are generally preferable to physical names.
12234 2002-09-02 Akim Demaille <akim@epita.fr>
12236 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12237 Reported by Raja R. Harinath.
12238 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12239 * bin/autoupdate.in: Use error instead of die.
12241 2002-09-01 Paul Eggert <eggert@twinsun.com>
12243 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12244 ordinary shell concatenation rather than echo+tr+sed command that
12245 runs afoul of a long-line-related sed bug in Solaris 8.
12247 * bin/autoheader.in (parse_args): --warning -> --warnings.
12249 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12250 stdout, as traditional "ls" does.
12251 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12252 _AC_COMPILER_EXEEXT_O): Likewise.
12253 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12255 * bin/autoconf.as: Add --prepend-include option. This patch was
12256 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12257 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12259 * bin/autoconf.in, configure: Regenerate.
12261 * doc/autoconf.texi (Special Shell Variables): Mention
12262 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12264 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12265 MAILPATH and set PS1, PS2, PS4 to default values, to work
12266 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12267 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12268 the Autoconf documentation specifies; fall back to "unset" only if
12269 this fails. Use a shell for-loop for this rather than an m4 loop,
12270 to shorten the output script.
12272 2002-08-30 Paul Eggert <eggert@twinsun.com>
12274 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12275 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12276 for the CDPATH problem. Document PWD.
12277 (Limitations of Builtins): Document the problem that "cd $foo" and
12278 "ls $foo" may refer to different directories in shells conforming
12279 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12280 example, since the old example is now out of date.
12282 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12283 FOO" and "ls FOO" talk about different directories; this catches
12284 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12285 spaghetti.
12287 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12288 of rolling our own unset.
12289 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12290 in practice we needn't worry about CDPATH if unset doesn't work.
12292 * Makefile.in, aclocal.m4, bin/Makefile.in,
12293 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12294 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12295 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12296 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12297 tests/Makefile.in: Regenerate with Automake 1.6.3.
12299 * config/config.guess, config/config.sub, config/mkinstalldirs:
12300 Update.
12302 * configure: Regenerate with self.
12304 2002-08-30 Kevin Ryde <user42@zip.com.au>
12306 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12307 default output.
12309 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12311 * bin/autom4te.in (Request::load): Correctly test for "do" read
12312 failure.
12314 2002-08-29 Akim Demaille <akim@epita.fr>
12316 * lib/Autom4te/General.pm (&xqx): New.
12317 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12318 hand, which is not portable.
12319 (&error): New.
12320 * bin/autom4te.in: Use them.
12321 Use &error instead of die.
12322 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12323 Adjust.
12325 2002-08-17 Paul Eggert <eggert@twinsun.com>
12327 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12328 default list of compilers to try, since it was long ago superseded
12329 by the ksh fc builtin. Suggested by Steven G. Johnson.
12331 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12333 * doc/autoconf.texi (Invoking autom4te): End the option table,
12334 fixing a bug introduced by the previous patch.
12335 (Limitations of Make): Add a 'target lookup' subentry in the
12336 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12338 2002-07-29 Mark D. Roth <roth@feep.net>
12340 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12341 options and use $AUTOM4TE_PATH.
12342 * doc/autoconf.texi: Remove documentation of autom4te
12343 --include-envvar and --site-macro-subdir options and document
12344 use of $AUTOM4TE_PATH.
12345 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12346 arguments from each language section.
12348 2002-07-29 Paul Eggert <eggert@twinsun.com>
12350 * doc/install.texi: Include copyright symbol in copyright notice.
12352 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12353 Replace with:
12354 (AM_MAKEINFOFLAGS): New macro.
12355 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12356 * Makefile.am (INSTALL): Use the new macros.
12357 Use -o rather than --output, since "missing" does not grok --output.
12359 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12361 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12362 comments do not always work. Never trust the exit status of
12363 `make -k'.
12365 2002-07-24 Kevin Ryde <user42@zip.com.au>
12367 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12368 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12370 2002-07-23 Paul Eggert <eggert@twinsun.com>
12372 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12373 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12374 apparently treats PATH="nonexistent" as if it contained ".".
12375 Bug reported by Stefan `Sec' Zehl.
12377 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12379 * doc/autoconf.texi (Limitations of Make): Mention the special
12380 handling of the obj/ directory by BSD make.
12382 2002-07-20 Kevin Ryde <user42@zip.com.au>
12384 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
12385 backslashes.
12387 2002-07-19 Akim Demaille <akim@epita.fr>
12389 * doc/autoconf.texi (Function Portability): `exit'.
12390 (Programming in M4sh): Ethymology of M4sh.
12392 2002-07-19 Akim Demaille <akim@epita.fr>
12394 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
12396 2002-07-18 Akim Demaille <akim@epita.fr>
12398 Version 2.53b.
12400 2002-07-18 Akim Demaille <akim@epita.fr>
12402 * config/config.guess, config/config.sub: Update.
12404 2002-07-18 Akim Demaille <akim@epita.fr>
12406 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
12407 Automake's parts.
12409 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
12410 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
12411 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
12413 2002-07-18 Akim Demaille <akim@epita.fr>,
12414 Alexandre Duret-Lutz <duret_g@epita.fr>
12416 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
12417 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
12419 2002-07-17 Russ Allbery <rra@stanford.edu>
12421 * doc/autoconf.texi (Initializing configure): Clarify the
12422 description of the tarname default.
12424 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
12426 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
12427 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
12428 latter was not run.
12430 2002-07-17 Akim Demaille <akim@epita.fr>
12432 * lib/Autom4te/General.pm (find_file): Browse the directories in
12433 the order they are given.
12435 2002-07-17 Akim Demaille <akim@epita.fr>
12437 * tests/wrapsh.as, tests/wrappl.as: Merge into...

12501 2002-06-27 Paul Eggert <eggert@twinsun.com>
12503 * config/install-sh: Quote $src. Prefer || to test's -o option,
12504 as per "Limitations of Builtins".

12509 "Limitations of Builtins".
12511 2002-06-15 Paul Eggert <eggert@twinsun.com>
12513 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
12514 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
12515 so that we consistently test the just-built programs.
12516 * tests/wrappl.as: Likewise.
12518 2002-06-12 Paul Eggert <eggert@twinsun.com>
12520 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

12534 * doc/autoconf.texi: Add more dir entries.
12536 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
12538 * bin/autom4te.in ($cache): Don't define using `$me', the name
12539 of the cache should not depend on the name under which autom4te
12540 was installed.
12542 2002-06-07 Akim Demaille <akim@epita.fr>
12544 * tests/tools.at (autoconf: forbidden tokens, basic)

12558 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
12559 AC_FUNC_FNMATCH_GNU.
12561 2002-06-07 Akim Demaille <akim@epita.fr>

12568 * bin/autom4te.in (warn_forbidden): When rejecting a token,
12569 suggest m4_pattern_allow.
12570 Suggested by Adam J. Richter.
12572 2002-06-07 Akim Demaille <akim@epita.fr>
12574 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
12575 ac_config_libobj_dir.
12576 (AC_CONFIG_LIBOBJ_DIR): New.
12577 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
12578 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
12579 Use ac_config_libobj_dir to find the replacement files.

12584 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
12585 * tests/mktests.sh (ac_exclude_list): Don't check

12624 * NEWS, doc/autoconf.texi (Particular Types): Document it.
12625 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it

12633 2002-05-22 Paul Eggert <eggert@twinsun.com>
12635 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
12636 from the default list of compilers to try. Suggested by
12637 Kate Hedstrom.
12638 * NEWS: Document the above.
12639 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
12641 2002-05-17 Paul Eggert <eggert@twinsun.com>
12643 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12644 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12645 This improves on an earlier suggestion by H. Peter Anvin.
12647 2002-05-16 Paul Eggert <eggert@twinsun.com>
12649 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12650 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12651 Both macros now accept an optional source-dir arg.
12652 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12654 * NEWS: Document this.
12655 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12657 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12658 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12659 not for GNU extensions; this undoes part of the 2000-11-03 change,
12660 reverting to 2.13-compatible behavior.
12661 Add new optional argument DIR.
12662 (AC_FUNC_FNMATCH_GNU): New macro.
12664 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12666 2002-05-08 Paul Eggert <eggert@twinsun.com>
12668 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12669 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12670 and it causes a 'test' syntax error if it fails.
12671 Bug reported by Stephen Gildea.
12673 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12674 If prototypes are supported, use them to check this at compile-time,
12675 instead of trying to check it at run-time. If we must do a run-time
12676 check, assume that setvbuf is standard when cross-compiling, as
12677 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12678 Bug reported by Paul D. Smith.
12680 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12681 argument specifying location of getloadavg.c. This removes a
12682 FIXME. This idea was taken from Jim Meyering's implementation in
12683 textutils.
12684 * doc/autoconf.texi (Particular Functions): Document this.
12685 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12686 that's what the code does; this fixes a bug reported by
12687 Paul D. Smith.
12689 2002-05-03 Akim Demaille <akim@epita.fr>
12691 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12692 autopoint instead of gettextize.
12693 ($uses_alocal): Rename as...
12694 ($uses_aclocal): this.
12695 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12696 Suggested by Bruno Haible.
12698 2002-05-03 Akim Demaille <akim@epita.fr>
12700 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12702 2002-04-29 Paul Eggert <eggert@twinsun.com>
12704 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12705 files to be 1 second older; just set them to be the same time.
12706 Also, sleep 1 second after the first aclocal, to work around
12707 problems with sub-second time stamps on the input files.
12709 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12711 * doc/autoconf.texi: Mention "set -e -x" lossage
12712 under node "Limitations of Builtins".
12714 2002-04-29 Akim Demaille <akim@epita.fr>
12716 * doc/install.texi: Better wording for setting variables when
12717 running configure.
12718 From Christian Cornelssen.
12720 2002-04-29 Akim Demaille <akim@epita.fr>
12722 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12723 of lack of $LINENO support, then the test will compare the $LINENO
12724 in testsuite vs. the lineno in the test file. This is wrong, of
12725 course.
12726 Be sure to protect it.
12727 Reported by Patrick Welche.
12729 2002-04-25 Akim Demaille <akim@epita.fr>
12731 * doc/autoconf.texi (Obsolete Macros): Typo.
12732 Reported by Vladimir Volovich.
12734 2002-04-25 Akim Demaille <akim@epita.fr>
12736 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12737 than some of the input files, hence, on the second run of aclocal,
12738 if some of its input are younger, make them older.
12739 Suggested by Paul Eggert.
12741 2002-04-25 Akim Demaille <akim@epita.fr>
12743 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
12744 Thanks to Paul Eggert.
12746 2002-04-25 Akim Demaille <akim@epita.fr>
12748 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12749 and ac_subst_vars be sh variables containing the list of
12750 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12751 DEFAULT diversion.
12752 (_AC_INIT_PREPARE): Use them to log them.
12753 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12754 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12755 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12756 _AC_SUBST_FILES and _AC_SUBST_VARS.
12757 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12759 2002-04-24 Akim Demaille <akim@epita.fr>
12761 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12762 autoheader, so that automake does not complain about a missing
12763 config.h.in that was to be created.
12765 2002-04-23 Akim Demaille <akim@epita.fr>
12767 * bin/autoheader.in (parse_args): --warning takes an argument.
12768 Fixes PR/220.
12770 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
12772 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
12773 and bb.out when cleaning up.
12775 2002-04-22 Akim Demaille <akim@epita.fr>

12789 2002-04-22 Akim Demaille <akim@epita.fr>
12791 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.

12819 * doc/autoconf.texi: Follow the outline suggested in the GNU
12820 Sample Texts sections of the Texinfo 4.2 manual. Most
12821 importantly, this makes sure that the copyright notices appear in
12822 all output formats. You probably need Texinfo 4.2 to generate
12823 the manual now.

12874 Adjust Autoconf and Autotest.

12877 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12878 * lib/autotest/general.m4 (AT_INIT): Likewise.
12879 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

12900 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
12901 ac_top_builddir when setting ac_abs_top_builddir.
12903 2002-04-06 Kevin Ryde <user42@zip.com.au>
12905 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
12906 (Portable Shell): Cross reference to Systemology.
12908 2002-04-05 Akim Demaille <akim@epita.fr>
12910 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
12911 directories when descending in a SUBDIRS.
12912 Reported by Ezra Peisach.
12914 2002-04-04 Andreas Schwab <schwab@suse.de>
12916 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
12917 contains no literal separators.
12919 2002-04-03 Akim Demaille <akim@epita.fr>
12921 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
12922 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
12923 Use dnl, not the KILL diversion.
12924 Extracted from...
12925 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12926 (AC_CONFIG_LINKS): here.
12927 Adjust.
12928 Don't use the KILL diversion, as it kills spurious output, which
12929 results in failures being hidden.
12930 Use m4_defn where appropriate.
12931 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12932 after the second argument.
12933 Use m4_defn.
12934 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12935 syntax, as it is provided by M4sugar.
12936 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
12938 2002-04-03 Andreas Schwab <schwab@suse.de>
12940 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
12941 expanded if $# <= 2.
12943 * bin/autoreconf.in (autoreconf): Run automake after rerunning
12944 aclocal.
12946 2002-04-03 Akim Demaille <akim@epita.fr>
12948 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
12949 (_AC_COMPILER_EXEEXT_REJECT): New.
12950 Also recognize *.bb and *.bbg as compilation byproducts.
12951 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
12952 (_AC_COMPILER_OBJEXT): Use them.
12953 Fixes Debian #138666.
12955 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
12957 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12959 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12960 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12961 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
12962 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
12963 (AC_C_CONST): Same.
12964 (AC_C_INLINE): Same.
12965 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
12966 * doc/autoconf.texi, NEWS: Document.
12967 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
12968 AC_C_CROSS.
12970 2002-04-02 Akim Demaille <akim@epita.fr>
12972 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
12973 _AS_MKDIR_P_PREPARE.
12975 2002-03-28 Kevin Ryde <user42@zip.com.au>
12977 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12978 to avoid versions of HP C which don't allow that.
12980 2002-03-27 Paul Eggert <eggert@twinsun.com>
12982 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12983 (AS_SHELL_SANITIZE): Invoke it.
12984 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
12986 2002-03-26 Akim Demaille <akim@epita.fr>
12988 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
12990 2002-03-26 Akim Demaille <akim@epita.fr>
12992 * doc/autoconf.texi (Introduction): The GNATS base moved.
12994 2002-03-25 Paul Eggert <eggert@twinsun.com>
12996 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12997 as POSIX requires, as it doesn't work with Zsh.
12998 * doc/autoconf.texi (Assignments): Document the problem.
13000 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
13002 * doc/autoconf.texi (Limitations of Make): Mention more issue
13003 about VPATH, overriding of macros in sub-makes, and handling of
13004 SHELL.
13006 2002-03-21 Paul Eggert <eggert@twinsun.com>
13008 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13009 problem with here-document buffer boundaries.
13011 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13012 when reinvoking the shell, to work around problems with installers
13013 who put strange things like "cd" commands in their environments.
13015 2002-03-19 Akim Demaille <akim@epita.fr>
13017 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
13018 From Aaron Ucko.
13020 2002-03-19 Akim Demaille <akim@epita.fr>
13022 * bin/autoscan.in (scan_file): Specify the location in `&used'
13023 invocations.
13024 From Nicolas Joly.
13026 2002-03-19 Akim Demaille <akim@epita.fr>
13028 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
13029 From Nishio Futoshi.
13031 2002-03-19 Akim Demaille <akim@epita.fr>
13033 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
13035 2002-03-18 Paul Eggert <eggert@twinsun.com>
13037 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
13038 (Limitations of Usual Tools): Add mkdir section.
13040 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13041 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13042 back on AS_DIRNAME to compute prefixes otherwise; this is
13043 roughly what mkinstalldirs does. That way, we need not have
13044 our own filename disassembler. The old disassembler did not
13045 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13047 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13048 Create at_test_all by a series of assignments,
13049 not by a single assignment of a long string. The latter causes ksh
13050 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13051 presumably because of a buffer overrun.
13053 2002-03-14 Paul Eggert <eggert@twinsun.com>
13055 * lib/autotest/general.m4 (at_times_skip):
13056 Renamed from at_times. Now a boolean.
13057 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13058 says 'times: not found'.
13060 2002-03-14 Akim Demaille <akim@epita.fr>
13062 * bin/autoreconf.in (&study_gettextize): New.
13063 (&autoreconf): Handle newest gettextize.
13064 Rerun aclocal if needed.
13065 Suggested by Andreas Schwab.
13067 2002-03-13 Akim Demaille <akim@epita.fr>
13069 * doc/autoconf.texi (Special Shell Variables): More about IFS.
13071 2002-03-13 Akim Demaille <akim@epita.fr>
13073 * doc/autoconf.texi (Header Portability): New.
13074 Add information about stdint.h and inttypes.h from Paul Eggert.
13076 2002-03-13 Akim Demaille <akim@epita.fr>
13078 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
13079 -p'.
13080 From Bob Proulx.
13082 2002-03-12 Akim Demaille <akim@epita.fr>
13084 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
13085 m4_require.
13087 2002-03-11 Andreas Schwab <schwab@suse.de>
13089 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
13090 does not do it if --with-lispdir is given.
13092 2002-03-08 Akim Demaille <akim@epita.fr>
13094 Version 2.53.
13096 2002-03-08 Akim Demaille <akim@epita.fr>
13098 * doc/autoconf.texi (Subdirectories): Clarify that the
13099 subdirectory should exist.
13101 2002-03-08 Akim Demaille <akim@epita.fr>
13103 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13105 2002-03-08 Akim Demaille <akim@epita.fr>
13107 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13108 aliases the actual variables, and modifications of the former
13109 affect the latter.
13111 2002-03-08 Akim Demaille <akim@epita.fr>
13113 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13114 because of C-c: have m4 output in tmp files, then mv them.
13116 2002-03-08 Akim Demaille <akim@epita.fr>
13118 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
13119 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
13120 * bin/ifnames.in: Copyright update.
13122 2002-03-08 Akim Demaille <akim@epita.fr>
13124 * doc/autoconf.texi (Invoking autom4te): New.
13126 2002-03-05 Akim Demaille <akim@epita.fr>
13128 * doc/autoconf.texi (Specifying Names): Clarification suggested by
13129 Kevin Ryde.
13131 2002-03-05 Akim Demaille <akim@epita.fr>
13133 Version 2.52i.
13135 2002-03-04 Akim Demaille <akim@epita.fr>
13137 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13138 * lib/autoconf/general.m4 (AC_INIT): More informative error
13139 message for LIBOBJ.
13141 2002-03-04 Akim Demaille <akim@epita.fr>
13143 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
13144 parallel builds.
13146 2002-03-04 Akim Demaille <akim@epita.fr>
13148 * doc/autoconf.texi (Transforming Names): Equality between target
13149 and host is irrelevant.
13150 (Specifying Names, Canonicalizing): Remove all references to the
13151 backward compatibility hooks. Rather, collect them all into...
13152 (Hosts and Cross-Compilation): this new section.
13153 * doc/install.texi (System Type): Ditto.
13154 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13155 that `--host' implies cross-compilation.
13157 2002-03-04 Akim Demaille <akim@epita.fr>
13159 * doc/autoconf.texi (Evaluation Macros): New.
13160 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13161 useless.
13162 (_m4_foreach): Define the variant with immediate evaluation so
13163 that it contains exactly the items, not an expression which
13164 evaluation is the current item.
13165 (m4_re_string, m4_re_word): Don't over quote them.
13167 2002-03-04 Akim Demaille <akim@epita.fr>
13169 Instead of having stacking `shift's evaluated at the end, let
13170 `foreach' loops immediately evaluate them.
13172 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13173 $*. This is the n-th time I change my mind, but hopefully this is
13174 the last...
13175 (m4_lquote): New.
13176 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13177 efficient.
13178 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13179 it was only a hack for m4_text_wrap.
13180 (m4_car2): Remove, replaced by...
13181 (m4_cdr): New.
13182 (_m4_foreach): Adjust.
13183 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13184 m4_bpatsubst for clarification.
13186 2002-03-04 Akim Demaille <akim@epita.fr>
13188 * doc/autoconf.texi (Changequote is Evil): New.
13190 2002-03-03 Kevin Ryde <user42@zip.com.au>
13192 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
13193 on old systems like SunOS.
13195 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
13197 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,

13201 of messages.
13203 2002-02-28 Akim Demaille <akim@epita.fr>
13205 * lib/autotest/general.m4 (AT_INIT): Suggest a title to the
13206 message to be sent.
13208 2002-02-28 Kevin Ryde <user42@zip.com.au>

13212 2002-02-25 Akim Demaille <akim@epita.fr>
13214 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
13215 From Akinori Musha.
13217 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
13219 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
13220 translate \r\n to \n.
13222 2002-02-07 Akim Demaille <akim@epita.fr>
13224 Version 2.52h.
13226 2002-02-07 Akim Demaille <akim@epita.fr>
13228 Fix Autoconf PR/209.
13229 Also reported by Frank Denis.
13231 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
13233 2002-02-07 Akim Demaille <akim@epita.fr>
13235 Fix Autoconf PR/207:
13236 AC_PREFIX_PROGRAM fails with dashed program names
13238 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
13239 variable when looking for the prefix program.
13240 Now it also works for shell variables.
13242 2002-02-07 Akim Demaille <akim@epita.fr>
13244 * doc/autoconf.texi (Limitations of Builtins): More about
13245 case/esac.
13247 2002-02-06 Akim Demaille <akim@epita.fr>
13249 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
13250 case/esac, some shells don't support it.
13251 Reported by Zack Weinberg.
13252 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
13254 2002-02-06 Akim Demaille <akim@epita.fr>
13256 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
13257 sure not to introduce newlines in at_groups.
13258 * lib/autotest/Makefile.am (autotest.m4f): Typo.
13260 2002-02-06 Akim Demaille <akim@epita.fr>
13262 * tests/torture.at (Configuring subdirectories): Skip if aclocal
13263 is not available.
13265 2002-02-05 Paul Eggert <eggert@twinsun.com>
13267 * doc/autoconf.texi (Specific Compiler Characteristics):
13268 Describe HP-UX cc bug workaround more accurately.
13269 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
13270 not unsigned long.
13271 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
13272 cross-compilers, too. This undoes some of the most recent change
13273 to this file.
13275 2002-02-05 Akim Demaille <akim@epita.fr>
13277 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
13278 to make sure they are up to date when `check' is run.
13280 2002-02-05 Akim Demaille <akim@epita.fr>
13282 * doc/autoconf.texi (Making testsuite Scripts): Document
13283 package.m4.
13285 2002-02-05 Akim Demaille <akim@epita.fr>
13287 * lib/freeze.mk: New.
13289 2002-02-05 Akim Demaille <akim@epita.fr>
13291 Implement `autom4te --freeze'.
13293 * bin/autom4te.in (&freeze): New.
13294 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
13295 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
13297 2002-02-05 Akim Demaille <akim@epita.fr>
13299 * bin/autom4te.in (&parse_args): Implement `frozen files are
13300 optional are the sum of the previous files on the command line'.
13301 Also, pass `--reload-state=' on them, so...
13302 (handle_m4): don't.
13303 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13304 (M4sh): Rely on M4sugar.
13305 (Autotest, M4sh, M4sugar): Use frozen files.
13307 2002-01-31 Akim Demaille <akim@epita.fr>
13309 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
13310 * doc/autoconf.texi (Initializing configure): Adjust.
13312 2002-01-30 Akim Demaille <akim@epita.fr>
13314 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
13315 alphanumeric to `-' instead of `_'.
13317 2002-01-30 Akim Demaille <akim@epita.fr>
13319 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
13320 for plain code, the other for cross-compilation code. The latter
13321 is now run with GCC only.
13322 * doc/autoconf.texi (Compilers and Preprocessors): New.
13324 2002-01-30 Akim Demaille <akim@epita.fr>
13326 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
13327 values.
13328 * doc/autoconf.texi (Initializing configure): Explain how to
13329 change AC_INIT default values.
13331 2002-01-29 Akim Demaille <akim@epita.fr>
13333 * tests/torture.at (Configuring subdirectories): Use configure.in,
13334 so that aclocal 1.4 works.
13335 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13337 2002-01-28 Akim Demaille <akim@epita.fr>
13339 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13340 needs an argument.
13342 2002-01-28 Akim Demaille <akim@epita.fr>
13344 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13345 AUTOTEST_PATH *after* it was set.
13346 Don't put `.' in the PATH: the user should be precise and `./' if
13347 needed. In addition, given that the test suite does some `cd', if
13348 `.' is in the path, the `tested programs' sections will report
13349 programs found in the test suite's directory, while during the
13350 tests (performed in their own directory), these programs are no
13351 longer visible. In other words, the results is confusing and
13352 useless.
13353 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
13355 2002-01-24 Akim Demaille <akim@epita.fr>
13357 Version 2.52g.
13359 2002-01-24 Akim Demaille <akim@epita.fr>

13362 * doc/autoconf.texi: Finally add Akim as an author.
13364 2002-01-24 Akim Demaille <akim@epita.fr>
13366 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13367 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13368 Bourne. Use /bin/sh.
13369 From Andreas Buening.
13371 2002-01-24 Akim Demaille <akim@epita.fr>
13373 * config/config.guess, config/config.sub, config/texinfo.tex:
13374 Update from masters.
13376 2002-01-24 Akim Demaille <akim@epita.fr>

13381 * config/missing.m4, config/sanity.m4, config/select.m4,
13382 * config/strip.m4: Remove, to ease sync'ing with any version of
13383 Automake.

13391 2002-01-21 Akim Demaille <akim@epita.fr>
13393 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
13395 2002-01-21 Akim Demaille <akim@epita.fr>
13397 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13398 message on invalid options.
13399 * bin/autom4te.in (parse_args): Don't use
13400 Autoconf::General::getopt with non valid options.
13402 2002-01-17 Jim Meyering <meyering@lucent.com>
13404 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13405 $ac_cv_exeext so we don't use an old, invalid, cached value.
13407 2002-01-11 Akim Demaille <akim@epita.fr>
13409 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
13410 Meyering.

13419 package.m4, since is really depends upon configure.ac, not
13420 configure.
13421 * doc/autoconf.texi (testsuite Scripts): Adjust.
13422 * tests/Makefile.am (package.m4): New.
13423 EXTRA_DIST it since its a source.
13425 2002-01-06 Akim Demaille <akim@epita.fr>
13427 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13428 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13429 and PACKAGE_BUGREPORT from here...
13430 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13431 arguments.
13432 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13433 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13434 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13435 * tests/tools.at (autoheader): Adjust.
13436 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.

13457 2001-12-14 Akim Demaille <akim@epita.fr>
13459 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13460 trailing files, don't apply `-rf' to files which might not be
13461 created by configure (core, core.*, and *.core), but just `rm -f'.
13462 Suggested by Jonathan Kamens.
13464 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13466 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13468 2001-12-14 Akim Demaille <akim@epita.fr>
13470 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13472 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13474 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13475 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13476 abs_srcdir, top_srcpath to abs_top_srcdir.
13477 (_AC_OUTPUT_FILES): Adjust.
13478 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13479 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13480 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13482 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13484 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13485 C/Fortran linking on HP/UX, by extracting the Fortran library
13486 search path from the LPATH line in the $F77 -v output.
13488 2001-12-12 Kevin Ryde <user42@zip.com.au>
13490 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13491 forbidden file descriptors table.
13493 2001-11-26 Akim Demaille <akim@epita.fr>
13495 * bin/autoscan.in (%c_keywords): Build it at top level.
13496 Map to 1 in order to simplify its uses.
13498 2001-11-26 Akim Demaille <akim@epita.fr>
13500 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13501 Remove $filepath, useless.
13502 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13503 variables, they are really part of the tokens.
13504 Split the input line on spaces and then look for tokens.
13505 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13506 because of `lex$U.$(OBJEXT)'.
13507 (&scan_files): Use "@list" instead of join.
13508 * doc/Makefile.am (CLEANFILES): Add *.fns.
13510 2001-11-26 Akim Demaille <akim@epita.fr>
13512 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13513 Remove, replaced by...
13514 * tests/wrappl.in: Be common for all the Perl executables.
13515 In particular autoscan and autoheader want -I.
13516 * configure.ac: Adjust.
13517 * lib/autoscan/headers: errno.h is portable.
13519 2001-11-26 Akim Demaille <akim@epita.fr>
13521 * bin/autoscan.in (used): New.
13522 Use it.
13524 2001-11-26 Akim Demaille <akim@epita.fr>
13526 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13527 directives.
13528 (&scan_sh_file): Remove a duplicate pattern.
13529 (&check_configure_ac): Use long options.
13530 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13532 2001-11-26 Akim Demaille <akim@epita.fr>
13534 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13535 Before, having a line containing the opening of a multi line
13536 comment made the whole line be ignored.
13538 2001-11-26 Akim Demaille <akim@epita.fr>
13540 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13541 (testsuite Scripts): Be one of its subsection.
13542 (Autotest Logs): New.
13544 2001-11-26 Akim Demaille <akim@epita.fr>
13546 Test groups are now run two directories deeper.
13548 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13549 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13550 at_top_builddir.
13551 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13552 top_srcdir, builddir and top_builddir.
13553 Use `at_*dir' relatively to the directory containing the
13554 suite, use `*dir' when relatively to the current group dir.
13556 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13558 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13559 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13560 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13561 spelling errors.
13563 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13565 * doc/autoconf.texi (Using System Type): Add an example of `case
13566 $host' usage so people quit using `case $target' everywhere.
13568 2001-11-22 Akim Demaille <akim@epita.fr>
13570 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13571 spotted by Jim Meyering.
13573 2001-11-16 Paul Eggert <eggert@twinsun.com>
13575 This patch implements a `long double' suggestion by Oliver Kiddle.
13577 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13578 static, to catch errors if the value isn't known at compile-time
13579 and the compiler supports dynamic arrays. Change its name from
13580 `_array_' to `test_array' to avoid potential name clashes.
13581 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13582 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13583 better than double. Catch a bug in GCC 2.95.2 x86.
13584 * doc/autoconf.texi (C Compiler): Document the above.
13585 * NEWS: Likewise.
13587 2001-11-13 Akim Demaille <akim@epita.fr>
13589 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13590 hand.
13591 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13593 2001-11-13 Akim Demaille <akim@epita.fr>
13595 * lib/autotest/general.m4 (AT_INIT): After having run the test
13596 group, go back to the initial directory, not to at_suite_dir.
13598 2001-11-13 Akim Demaille <akim@epita.fr>
13600 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13601 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13602 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13603 option.
13604 (AT_CHECK_CONFIGURE): Use absolute paths.
13605 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13606 The problem is still the old one: there is no means in M4 (that I
13607 know about) to create a defining macro, because there is no means
13608 to create `$1' etc., therefore, the defining macro ``swallows''
13609 all the arguments meant to the defined macro.
13611 2001-11-13 Akim Demaille <akim@epita.fr>
13613 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13614 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13615 configure.ac.
13616 * tests/aclocal.m4: Remove, as it is no longer used.
13618 2001-11-13 Akim Demaille <akim@epita.fr>
13620 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13621 variable names when referring to a single test group, or to
13622 `suite' when referring to the whole test suite.
13623 `at_last_test' is removed: m4 compute at_format itself.
13624 (at_stdout, at_stder1, at_stderr): New variables.
13625 (AT_CHECK): Use them.
13627 2001-11-13 Akim Demaille <akim@epita.fr>
13629 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13630 in PATH.
13631 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13632 Do it as soon as a test fails, don't wait till the end of the test
13633 suite.
13634 Don't remove $as_me.[0-9]*, since these files no longer exist.
13636 2001-11-13 Akim Demaille <akim@epita.fr>
13638 * tests/tools.at: Use absolute paths, since we are no longer run
13639 in place.
13641 2001-11-13 Akim Demaille <akim@epita.fr>
13643 Now that tests are running in their own private dir, there is no
13644 need to list the files to remove at the end of tests groups.
13646 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13647 (AT_data_files, at_data_files): Remove.
13648 (AT_CLEANUP, AT_DATA): Simplify.
13649 (AT_INIT): Adjust.
13650 Remove the group dir if !debug && !failed.
13651 * tests/atspecific.m4: Adjust.
13653 2001-11-13 Akim Demaille <akim@epita.fr>
13655 Start a new layout for Autotest: `testsuite' creates
13656 `testsuite.dir' in which the at-check-line etc. files are to be
13657 found, and `testsuite.dir/003' where the test group 3 is run.
13659 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13660 at_check_line_file, at_format, at_test_normalized, at_group_dir
13661 are new variables.
13662 Create the directories.
13663 Use absolute paths for at- files.
13664 (AT_CHECK): Adjust.
13666 2001-11-11 Michael Matz <matz@kde.org>
13668 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13669 (m4_car2): New.
13670 (m4_car): Properly quote arguments.
13672 2001-11-13 Akim Demaille <akim@epita.fr>
13674 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13675 with stricter rules on LIBOBJS.
13677 2001-11-12 Paul Eggert <eggert@twinsun.com>
13679 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13680 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13681 __PROTOTYPES too.
13683 2001-11-12 Akim Demaille <akim@epita.fr>
13685 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13687 2001-11-12 Akim Demaille <akim@epita.fr>
13689 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13690 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13691 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13692 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13693 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13694 specify to what the macro should be defined (typically to 1).
13696 2001-11-12 Akim Demaille <akim@epita.fr>
13698 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13699 From Jim Meyering.
13701 2001-11-12 Akim Demaille <akim@epita.fr>
13703 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13704 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13705 definition used by Automake where LEX is +/- "${missing} lex" and
13706 `missing' itself contains variables.
13708 2001-11-12 Akim Demaille <akim@epita.fr>
13710 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13711 Now that M4sh pushes BODY, the comments were output at the end of
13712 the test suites.
13714 2001-11-08 Akim Demaille <akim@epita.fr>
13716 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13717 that we can trace macros from aclocal.m4.
13718 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13719 obsoleted, and redirect to the former anyway.
13720 Reported by Ralf Corsepius.
13722 2001-11-08 Akim Demaille <akim@epita.fr>
13724 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13725 processed only if present.
13726 * tests/torture.at (Configuring subdirectories): Use autoreconf
13727 instead of successive calls to autoconf.
13728 Add a nonexistent subdirectory to exercise the patch above.
13729 Reported by Ralf Corsepius.
13731 2001-11-08 Kevin Ryde <user42@zip.com.au>
13733 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13734 doesn't accept .S files.
13736 2001-11-07 Akim Demaille <akim@epita.fr>
13738 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
13739 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
13740 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13741 * bin/autom4te.in (warn_forbidden): New.
13742 (handle_output): Use it.
13743 Read m4_pattern_forbid with messages.
13745 2001-11-05 Akim Demaille <akim@epita.fr>
13747 * bin/autom4te.in (--normalize): Remove.
13748 * lib/autom4te.in: Adjust.
13750 2001-11-05 Akim Demaille <akim@epita.fr>
13752 * tests/Makefile.am (testsuite): Rename this target as...
13753 ($(TESTSUITE)): this.
13754 From Nicolas Joly.
13756 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13758 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13759 the --prefix option, also remove it's argument.
13761 2001-11-05 Akim Demaille <akim@epita.fr>
13763 * doc/autoconf.texi (testsuite Invocation): Update.
13764 (Writing testsuite.at): Update.
13766 2001-11-03 Akim Demaille <akim@epita.fr>
13768 * doc/autoconf.texi: s/@code/@command/ where appropriate.
13770 2001-11-03 Akim Demaille <akim@epita.fr>
13772 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13773 (&file_name_is_absolute): New, wrappers around routines from
13774 File::Spec.
13775 Use and export them.
13776 (&find_configure_ac): Optionally take a directory where to look at.
13777 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13778 the arguments.
13779 Default @ARGV to `.', not find_configure_ac.
13780 (&autoreconf): Argument is a directory.
13781 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13782 * doc/autoconf.texi (autoreconf Invocation): Update.
13784 2001-11-03 Akim Demaille <akim@epita.fr>
13786 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13787 (@export_forward_subs): New.
13788 Add basename, dirname, and fileparse.
13789 (@EXPORT): Adjust.
13790 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13791 Don't look for aclocal flags if we already know aclocal is not
13792 used.
13793 Move aclocal.m4t only if it exists.
13794 Reported by Ezra Peisach.
13796 2001-11-03 Akim Demaille <akim@epita.fr>
13798 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13799 passed on command line, defaulting to ./configure.ac if present.
13800 (&maybe_autoreconf, File::Find): Remove, unused.
13801 (&autoreconf): If autoconf is not used, don't try to trace.
13803 2001-11-02 Akim Demaille <akim@epita.fr>
13805 * configure.ac: Bump to 2.52g.
13807 2001-11-02 Akim Demaille <akim@epita.fr>
13809 Version 2.52f.
13811 2001-11-02 Akim Demaille <akim@epita.fr>
13813 * config/config.guess, config/config.sub, doc/standards.texi:
13814 * config/lispdir.m4: Update from masters.
13815 * configure.ac: Bump to 2.52f.
13817 2001-11-02 Akim Demaille <akim@epita.fr>
13819 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13820 Don't run aclocal when aclocal.m4 is not from aclocal.
13821 From Ezra Peisach.
13822 Don't run libtoolize and gettextize if --install is not given.
13824 2001-11-01 Paul Eggert <eggert@twinsun.com>
13826 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13827 be invoked before _AS_LINENO_PREPARE.
13828 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13829 than character ranges.
13831 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13832 invoking AS_BASENAME. Set the locale variables to 'C' if
13833 possible, as POSIX requires this to get the traditional
13834 behavior.
13835 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13837 2001-10-31 Paul Eggert <eggert@twinsun.com>
13839 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13840 with {}, as that triggers a bug in Bash 2.05.
13842 (_AS_LINENO_PREPARE): Use Sed rather than
13843 Awk. Fix the sed prepass to work even if there are multiple
13844 instances of $LINENO on the same line. Do not substitute for
13845 other variables like $LINENOT. Do not check file dates; such a
13846 check is unreliable on sufficiently fast machines, and removing
13847 the check makes the code simpler and more reliable. Check for
13848 output and chmod failures.
13850 * doc/autoconf.texi (Special Shell Variables): Document
13851 the above.
13853 2001-10-31 Akim Demaille <akim@epita.fr>
13855 * tests/Makefile.am (atconfig): Remove this target, Automake
13856 handles it now.

13860 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not

13865 2001-10-26 Paul Eggert <eggert@twinsun.com>
13867 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13868 lib/Autom4te/Struct.pm:
13869 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13870 with 5.005_02.
13872 * doc/autoconf.texi (Special Shell Variables): Document some
13873 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13875 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13876 (_AS_LINENO_PREPARE): Use it instead of shell eval, since

13896 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13897 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13898 POSIX decided to standardize on the int flavor of strerror_r.
13899 Always do char* test, as there's no reason not to.
13900 Assign to a char* var, to catch strerror_r that returns int*.
13902 * doc/autoconf.texi (Particular Functions):
13903 Document the above changes. Also, document the fact that
13904 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.

13929 Remove, dead.
13930 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13931 `intl' is already present, as it refuses unless --force.
13932 (&parse_args): Use -I, --include instead of the old Autoconf
13933 options.

13968 (AS_BASENAME_EXPR): New macro.
13969 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13970 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13971 and fall back on 'sed' only if the other two fail. This makes
13972 AS_BASENAME act more like AS_DIRNAME.
13973 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13974 contains white space.
13975 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

13977 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
13978 Allow "dirname //FOO" to return either / or //, as POSIX allows
13979 either behavior.

14121 ourselves with CONFIG_SHELL.
14123 2001-10-05 Paul Eggert <eggert@twinsun.com>
14125 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

14208 and invoke a new argument $4 if either is discovered.

14210 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

14244 * tests/fortran.at (GNU Fortran 77): there.
14245 * doc/autoconf.texi (autoconf Invocation): Fix the example:

14252 Raja R Harinath:

14255 enough.
14256 Pass the CLI arguments to `$as_me.lineno'.

14351 * tests/Makefile.am (package.m4): Remove.
14353 2001-09-22 Akim Demaille <akim@epita.fr>
14355 Rely on `$LINENO' when possible instead of `__oline__'.
14357 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
14358 `$LINENO' support replacement when not supported.
14359 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
14360 them explicitly to be sure they are not output before this section
14361 (via m4_require). Cosmetic only.
14362 * lib/autoconf/c.m4, lib/autoconf/general.m4,
14363 * lib/autoconf/programs.m4: Replace all the occurrences of

14367 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
14369 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
14370 character (u: -> ue) in a code comment.
14371 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
14372 it works.
14374 2001-09-21 Akim Demaille <akim@epita.fr>
14376 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
14377 Suggested by Jim Meyering.
14379 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14381 * lib/autoconf/programs.m4: Use extensions listed in
14382 $ac_executable_extensions when looking for programs.

14386 * lib/autoconf/general.m4: Fix a small Englisho.

14394 PATH_SEPARATOR.
14395 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

14398 * lib/autotest/general.m4: Replace occurrences of ':' in
14399 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14401 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14403 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14404 arguments. Fixed a typo.
14406 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14408 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

14411 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14413 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

14420 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14422 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14423 already have $file). Set output files to binary mode (helps avoid
14424 CR issues on DOSish systems).
14426 2001-09-19 Akim Demaille <akim@epita.fr>
14428 * lib/autotest/general.m4: Englishoes.
14429 From Tim Van Holder and Alexey Mahotkin.
14431 2001-09-18 Paul Eggert <eggert@twinsun.com>
14433 * doc/autoconf.texi (Common Shell Constructs): New node,
14434 documenting AS_DIRNAME.
14435 (Limitations of Usual Tools): Refer to it when discussing dirname.
14436 Also, update discussion of POSIX standard to reflect latest draft.
14438 * lib/autoconf/c.m4:
14439 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14441 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14442 Do not pass a first argument with leading '-'
14443 to expr, by parenthesizing initial integers that might be negative.
14445 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14446 now merely checks whether it is an error to pass an argument
14447 to getpgrp.
14449 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14450 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14451 whether it is a (compile-time) error to pass an argument to
14452 getpgrp. This simpler test supports the revised documentation,
14453 and is all that AC_FUNC_GETPGRP's users really need.
14455 2001-09-18 Akim Demaille <akim@epita.fr>
14457 * doc/autoconf.texi (Limitations of Make) <$<>: New.
14459 2001-09-18 Akim Demaille <akim@epita.fr>

14467 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14468 correctly.
14469 Add test for AS_BASENAME.
14470 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14471 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14472 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14473 * tests/base.at: Fixed the expected responses. The old ones were
14474 one line out...
14475 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14476 the documentation claims it should (and how it behaved in 2.13).
14478 2001-09-18 Akim Demaille <akim@epita.fr>
14480 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14481 the AC_CONFIG_COMMANDS invocation.
14482 This also solves the name clash problems.
14483 Don't set the package's ID.
14484 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14485 No longer to be shipped.
14486 (version.in): Remove.
14487 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14488 * lib/autoconf/status.m4: Adjust.
14489 Use `m4_PACKAGE_STRING'.
14490 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14491 the only optional argument is the name of the test suite.
14492 Expect `package.m4' to define the package signature.
14493 * lib/autom4te.in (Autotest): Add `package.m4?'.
14494 * tests/Makefile.am (package.m4): New.
14495 * tests/suite.at: ifnames is a victim.
14497 2001-09-18 Akim Demaille <akim@epita.fr>
14499 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14500 AC_LIBSOURCE, AC_CONFIG_FILES.
14501 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14502 program version string doesn't match the package's.
14503 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14504 after `(cached)'.

14508 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14509 Allow expression to return any value that can fit into unsigned long
14510 (not int, as before). Check for output errors.
14512 2001-09-17 Bruno Haible <haible@ilog.fr>
14514 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14515 Always include <stdio.h> and <stdlib.h>. Evaluate
14516 the expression in an extra function before these includes. Call
14517 fprintf "%d" only after ensuring the argument is of type 'int'.
14518 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14520 2001-09-17 Paul Eggert <eggert@twinsun.com>
14522 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14523 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14524 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14525 when they don't exist.
14527 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14528 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14529 need it.
14531 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14532 version with the version used by fileutils 4.1, except use
14533 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14534 we don't need it.
14536 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14538 2001-09-13 Akim Demaille <akim@epita.fr>
14540 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
14541 _first_.
14542 Reported by Gerrit P. Haase.

14546 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

14567 AT_tests_all for consistency.

14570 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
14572 2001-09-13 Akim Demaille <akim@epita.fr>
14574 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
14576 2001-09-13 Akim Demaille <akim@epita.fr>
14578 * lib/autotest/general.m4 (AT_INIT): Create and remove
14579 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14580 test suites can cohabit.
14582 2001-09-13 Akim Demaille <akim@epita.fr>
14584 * tests/mktests.sh: Don't output banners for empty test files.
14586 2001-09-13 Akim Demaille <akim@epita.fr>
14588 Test suites can be run independently of configure.

14652 2001-09-07 Akim Demaille <akim@epita.fr>
14654 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5

14656 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package

14669 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
14670 in addition, it introduces useless differences in logs.

14682 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'
14683 to avoid GCC warnings.
14684 From Uwe Seimet.
14686 2001-09-05 Akim Demaille <akim@epita.fr>
14688 * bin/autom4te.in: --language is -l, not -s.
14690 2001-09-05 Akim Demaille <akim@epita.fr>

14693 the maintainer is dumb enough to do that...
14695 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14696 excellence in M4 quotation: consider `__file__' is active.

14729 New, extracted from main.
14730 Use IO::File wherever possible.

14759 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
14761 2001-08-31 Akim Demaille <akim@epita.fr>
14763 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
14764 (testsuite Scripts): There is no such thing as `atconfig.in'.
14765 And actually one diagram is missing: test suite runtime.
14767 2001-08-31 Akim Demaille <akim@epita.fr>
14769 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
14770 inverse order.
14772 2001-08-31 Akim Demaille <akim@epita.fr>
14774 * bin/autoupdate.in (@include): `installcheck' revealed the path
14775 to m4sugar was lacking!
14777 2001-08-31 Akim Demaille <akim@epita.fr>
14779 * man/Makefile.am (.x.1): We really have to pass
14780 autom4te_perllibdir.
14782 2001-08-31 Akim Demaille <akim@epita.fr>
14784 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
14785 debug scripts, in particular passing explicitly listed tests to
14786 run is stupid.
14788 2001-08-31 Akim Demaille <akim@epita.fr>
14790 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
14791 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
14792 Use directly autom4te, not autoconf.
14793 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
14795 2001-08-31 Akim Demaille <akim@epita.fr>
14797 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
14798 * bin/autoheader.in (%symbol): Strip arguments of macros.
14800 2001-08-31 Akim Demaille <akim@epita.fr>
14802 * doc/autoconf.texi: Catch up -I, --include changes.
14804 2001-08-31 Akim Demaille <akim@epita.fr>
14806 * bin/autom4te.in (&parse_args): Die on unknown languages.
14807 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
14808 need for autoconf.
14809 Promote --include over --macrodir and other obsolete options.
14811 2001-08-31 Akim Demaille <akim@epita.fr>
14813 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
14814 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
14815 * bin/autom4te.in ($autoconf): Pass --force.
14816 `print $out' doesn't print `$_' but `$out'.
14817 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
14818 (autoheader): Pass --force since the test suite goes too fast for
14819 the time stamps.
14820 Adjust to the new autoheader messages.
14822 2001-08-31 Akim Demaille <akim@epita.fr>
14824 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
14825 Check the completeness of the #template.
14826 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
14827 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
14828 invocation.
14830 2001-08-31 Akim Demaille <akim@epita.fr>
14832 * lib/Autom4te/General.pm (&find_file, &update_file): New.
14833 * bin/autoupdate.in, bin/autoheader.in: Adjust.
14834 Drop AC_MACRODIR dead for real.
14835 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14836 `autoheader: `config.hin' is created'.
14837 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14839 2001-08-31 Akim Demaille <akim@epita.fr>
14841 * bin/autoheader.in: Rewrite in Perl.
14842 * tests/autoheader: Adjust.
14844 2001-08-31 Akim Demaille <akim@epita.fr>
14846 * bin/autoconf.in (--include, -I): New option.
14847 Map --localdir, --autoconf-dir onto it.
14848 Forward autom4te's options instead of interpreting them.
14849 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14850 There is no such envvar since the inception of autom4te.cfg.
14851 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14852 * bin/autoupdate.in: Adjust, and perform more control.
14853 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
14854 * tests/autoconf: Dittowise.
14856 2001-08-31 Akim Demaille <akim@epita.fr>
14858 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
14859 * bin/autom4te.in (&find_file): Support `FILE?' standing for
14860 optionally `FILE'.
14861 Use -e, not -f, since /dev/null for instance is OK.
14862 (&parse_args): Adjust.
14863 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
14865 2001-08-31 Akim Demaille <akim@epita.fr>
14867 * configure.ac: Also find tested executables in bin.
14868 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
14869 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
14870 installed peer executables, only PATH is allowed to resolve it.
14871 Pass `autoconf_dir' via options, not via invisible envvars.
14872 * lib/Autom4te/General.pm (&find_peer): Remove.
14873 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14874 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14875 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14876 find the executables for it.
14877 * tests/Makefile.am: Major cleanup. Too lazy to document...
14878 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14879 We only need PERL.
14880 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14881 indeed related to running the test suite, while passing
14882 --autoconf-dir and others is related to running non installed
14883 Autoconf executables. So don't do that, leave it to...
14884 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14885 * tests/autoscan: New.
14886 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
14887 refer to library files: rely on --language.
14889 2001-08-29 Akim Demaille <akim@epita.fr>
14891 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
14892 s/--set/--language/.
14894 2001-08-29 Akim Demaille <akim@epita.fr>
14896 * doc/autoconf.texi: Strip the @nodes.
14897 Suggested by Paul Eggert.
14898 (Initializing configure): Typo.
14900 2001-08-29 Akim Demaille <akim@epita.fr>
14902 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
14903 Suggested by Paul Eggert.
14905 2001-08-29 Akim Demaille <akim@epita.fr>
14907 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
14908 download in a tmp dir.
14910 2001-08-29 Akim Demaille <akim@epita.fr>
14912 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
14913 case insensitive OSes out there :(
14914 From Tim Van Holder.
14916 2001-08-29 Akim Demaille <akim@epita.fr>
14918 * lib/autom4te.in: New.
14919 * lib/Makefile.am (edit, autom4te.cfg): New.
14920 * bin/autom4te.in (BEGIN): Simplify.
14921 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
14922 (&load_configuration): New. Use it.
14923 (&parse_args): Support --mode, --set, and --melt.
14924 * bin/autoconf.in: Simplify and adjust.
14925 * tests/Makefile.am (AUTOMAKE): Use --set.
14926 * tests/atlocal.in: Adjust.
14927 * BUGS: distcheck and check are weak.
14929 2001-08-29 Akim Demaille <akim@epita.fr>
14931 * lib/autotest/general.m4: Use
14932 foo=`(command) 2>/dev/null`
14933 not
14934 foo=`command` 2>/dev/null
14935 (at-devnull): Rename as...
14936 (AT-devnull): this.
14937 (--clean): Remove AT-* files too.
14938 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
14939 Reported by Nicolas Joly.
14941 2001-08-28 Akim Demaille <akim@epita.fr>
14943 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
14944 quotes inside single quotes.
14945 Reported by Nicolas Joly.
14947 2001-08-28 Kevin Ryde <user42@zip.com.au>
14949 * doc/autoconf.texi (Function Portability): Mention C right shifts.
14951 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
14953 * lib/autotest/general.m4: Reword some messages.
14954 (AT_INIT): Check for the `times' builtin before using it.
14955 Support test ranges as arguments to the testsuite.
14956 Have -e imply -d as the help text suggested.
14958 2001-08-27 Akim Demaille <akim@epita.fr>
14960 * Makefile.maint: Formatting changes.
14961 (do-po-update, po-update, cvs-update, update): New targets.
14962 (AMTAR): Remove.
14964 2001-08-27 Akim Demaille <akim@epita.fr>
14966 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

14973 * lib/autotest/general.m4 (AT_INIT): Log the command line.
14974 Support `VAR=VAL' as arguments.
14975 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
14976 may be set via the command line.
14978 2001-08-27 Akim Demaille <akim@epita.fr>
14980 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
14981 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
14982 first the build dirs, then the src dirs.

14985 2001-08-27 Akim Demaille <akim@epita.fr>

14988 at_data_files earlier.
14989 (--clean, -c): New option.
14990 * tests/Makefile.am: Use this option.
14992 2001-08-27 Akim Demaille <akim@epita.fr>
14994 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
14995 `ac_top_builddir' to mimic Automake's vocabulary, which much more
14996 readable.
14997 Adjust callers.
14998 * doc/autoconf.texi (Configuration Actions): Document the vars
14999 available in commands.
15000 Emphasize the risks of collisions in init-cmds.

15004 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
15005 (Initializing configure): this new node.
15007 2001-08-27 Akim Demaille <akim@epita.fr>

15020 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move
15021 to...
15022 * lib/autoconf/autoheader.m4: this new file.
15023 * lib/autoconf/general.m4 (AH_OUTPUT, AH_VERBATIM)
15024 (_AH_VERBATIM_OLD, AH_TEMPLATE, _AH_TEMPLATE_OLD, AH_TOP, AH_BOTTOM):
15025 Move to...

15028 2001-08-27 Akim Demaille <akim@epita.fr>
15030 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
15031 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
15032 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
15033 -> ac_dir).
15034 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
15035 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
15037 2001-08-27 Akim Demaille <akim@epita.fr>
15039 * lib/autoconf/autoconf.m4 (AC_CONFIG_COMMANDS)

15062 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
15063 (AMTAR): Help automake define it.
15064 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
15065 needed, 1.5 can have a macro and a target with the same name.
15066 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
15067 * m4/strip.m4: New.

15080 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
15081 Adjust callers.
15082 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
15083 the name of the directory they're in, instead of the filename,
15084 since version.m4 is now in m4sugar, but m4_acversion must not be
15085 classified as an Autoconf macro.
15086 ($input_m4): Don't qualify the path to m4sugar.
15087 Rather, pass autoconf_dir to m4.
15088 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
15089 * tests/suite.at: Require 2.52c.
15091 2001-08-27 Akim Demaille <akim@epita.fr>

15103 of config.log on traps.
15104 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
15105 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
15106 for config.status'.
15107 Open the log as soon as possible.
15108 Use the same log introduction as configure's.
15110 2001-08-22 Paul Eggert <eggert@twinsun.com>
15112 * doc/autoconf.texi (Indices): New node.
15113 Move indices out of the top level menu and into this submenu.
15115 2001-08-22 Akim Demaille <akim@epita.fr>
15117 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
15118 AC_TRY_COMMAND.
15119 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
15121 2001-08-22 Akim Demaille <akim@epita.fr>
15123 * lib/autoconf/general.m4 (AC_SHELL_PATH_WALK, AC_CHECK_PROG)

15128 (AC_PROG_RANLIB, AC_PROG_YACC, AC_PROG_LEX, _AC_DECL_YYTEXT)
15129 (AC_PROG_INSTALL, AC_PROG_LN_S, AC_RSH): Move to...
15130 * lib/autoconf/programs.m4: here.
15131 (_AC_DECL_YYTEXT): Rename as...
15132 (_AC_PROG_LEX_YYTEXT_DECL): this.

15160 * configure.ac (AT_CONFIG): Fix the path.
15161 * m4/atconfig.m4 (AT_CONFIG): Don't use EOF but ATEOF so that 2.52
15162 can be used.
15164 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
15166 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
15167 program with AC_LANG_PROGRAM before feeding it to
15168 AC_COMPILE_IFELSE. Cleanup grep usage.
15170 2001-08-20 Akim Demaille <akim@epita.fr>
15172 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
15173 * NEWS, README, README-alpha, TODO, tests/README: This package is
15174 `Autoconf', not `autoconf' (the executable).
15176 2001-08-20 Akim Demaille <akim@epita.fr>
15178 Info readers seem to need `Index' in the index node title :(
15180 * doc/autoconf.texi: Reverse the 2001-08-15 change which
15181 simplified index node names.
15183 2001-08-20 Akim Demaille <akim@epita.fr>
15185 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
15186 arguments are not literals.
15187 * doc/autoconf.texi (Input) <AC_INIT>: Arguments must be literals.

15225 2001-08-20 Akim Demaille <akim@epita.fr>
15227 Huh!?!?! There are still some user EOF tags used, which prevents
15228 their use in AC_CONFIG_COMMANDS for instance...
15230 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
15231 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

15294 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
15295 `$0.log' as for projects where testsuite is in src, we'd have
15296 testsuite.log created in src.

15312 * doc/autoconf.texi: Work around Texinfo buglets.
15313 (Transformation Rules): One example is enough, users are expected
15314 to have their brains on. And BTW, use DESTDIR.
15315 (dvar): New macro. Use it.
15317 2001-08-17 Akim Demaille <akim@epita.fr>
15319 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

15325 * bin/autom4te.in: --normalize is a new option.
15326 * bin/autoconf.in: Use it.

15365 (local-check): Run changelog-check. last.
15366 (alpha): Don't depend upon local-check, since...
15367 (cvs-dist): depends upon it.
15369 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
15371 * tests/Makefile.am: Use a clean-local rule to remove
15372 autom4te.cache (it's a directory, not a file.
15373 * Makefile.am: Ditto (but maintainer-clean-local).
15375 2001-08-15 Akim Demaille <akim@epita.fr>
15377 * bin/autom4te.in (@m4_warning): New.
15378 (&handle_m4): Use it.
15379 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15380 warnings are issued at each run.
15381 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15382 is in the src tree.
15384 2001-08-15 Akim Demaille <akim@epita.fr>
15386 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
15387 don't waste time running `autoupdate --version' works.
15388 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
15390 2001-08-13 Akim Demaille <akim@epita.fr>
15392 * doc/autoconf.texi (ma): Rename this index as...

15415 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
15416 to the INSTALL file.

15449 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15451 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15452 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15453 * doc/autoconf.texi (C Compiler Characteristics): Update
15454 documentation for AC_C_BIGENDIAN.
15456 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15458 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15459 magic values from an object file when cross-compiling.
15460 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15462 2001-08-10 Akim Demaille <akim@epita.fr>
15464 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15465 effects.
15466 Suggested by Russ Allbery.
15468 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15470 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15471 current $prefix to the sub-configures.
15473 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15475 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15476 extension (needed on BeOS). Reported by Guido van Rossum.
15478 2001-08-09 Akim Demaille <akim@epita.fr>
15480 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15482 2001-08-07 Akim Demaille <akim@epita.fr>
15484 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15485 removed.
15486 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15487 No need to remove the files before and after the each test, before
15488 each test and at the end of the suite is enough.
15489 Display only the children `times', not the shell's.
15490 If the test failed or was skipped, at-times is not available.
15492 2001-08-07 Akim Demaille <akim@epita.fr>
15494 Always produce testsuite.log, including when there are no
15495 failures. This helps getting information on skipped tests, and
15496 duration of the tests. Err, implement the latter btw.
15498 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15499 Dump information on the first run of each test.
15500 (AT_CLEANUP): Create `at-times' containing the duration of the
15501 test group.
15503 2001-08-07 Akim Demaille <akim@epita.fr>
15505 The use of `dumpstat' revealed that `len' was used although it
15506 should not. m4_text_wrap was using it, but in the Autoconf world
15507 where it is legal. Hence (i) test M4sh in its own world, not
15508 Autoconf's, and (ii), ahem, fix the bug :)
15510 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15511 does not like `' instead of [].
15512 (AT_INIT): Forbid `^_?AT_'.
15513 And don't output such tokens.
15514 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15515 `script.as', and `autom4te.cache'.
15516 Remove `empty' and `macro' which are no longer used.
15517 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15518 * tests/m4sugar.at: Use it.
15519 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15521 2001-08-07 Akim Demaille <akim@epita.fr>
15523 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15525 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15527 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15529 2001-08-04 Akim Demaille <akim@epita.fr>
15531 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15532 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15533 AC_TRY_LINK.
15534 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15535 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15536 (AC_F77_MAIN): Likewise.
15538 2001-08-04 Akim Demaille <akim@epita.fr>
15540 Don't rely on M4sugar outputting the patterns in files, since we
15541 might process the output _without_ running m4, hence without these
15542 files.
15544 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15545 * bin/autom4te.in (@Request::includes): Remove, unused.
15546 (@Request::source): Rename as...
15547 (@Request::input): this.
15548 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15549 (&handle_output): Fetch the patterns from the traces.
15550 `$forbidden' and `$allowed' are constant: use m//o.
15551 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15552 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15554 2001-08-04 Akim Demaille <akim@epita.fr>
15556 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15557 autoconf', i.e., in addition to caching traces, cache the output.
15559 * bin/autom4te.in (Request::cache): Rename as...
15560 (Request::id): this.
15561 ($cache, $icache, $tcache, $ocache): New.
15562 (&handle_m4): Save M4 output in the cache instead of $tmp.
15563 (&handle_output): Adjust.
15564 (&up_to_date_p): Check that the output cache is up to date too.
15565 (top level): Run `&handle_m4' iff force or the cache is invalid.
15566 Run `&handle_output' if the output cache is more recent.
15568 2001-08-04 Akim Demaille <akim@epita.fr>
15570 * bin/autom4te.in ($force): New.
15571 (&parse_args, &print_usage): -f, --force is a new option.
15572 (&handle_output): CPP directives might have spaces after `#'.
15573 (&parse_args): The first file only can be frozen.
15575 2001-08-04 Akim Demaille <akim@epita.fr>
15577 Don't let autom4te compute the `include' traces several times:
15578 first check that the trace cache file is up to date, and then
15579 compare its timestamp with that of the output.
15581 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15582 the preamble. Don't require 5.005 as Autom4te::General does it,
15583 and better yet (use `use', not `require'!).
15584 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15585 Class::Struct as Autom4te::Struct.
15586 * lib/Autom4te/General.pm (File::stat): Use it.
15587 (&mtime): New, export it.
15588 * bin/autom4te.in: Use it.
15589 Declare `$req' is invalid if it is outdated.
15590 Don't declare it valid before saving it if something went wrong.
15592 2001-08-04 Akim Demaille <akim@epita.fr>
15594 Autom4te shall not encode Autoconf data, and preselecting traces
15595 must be proposed to the users.
15597 * bin/autom4te.in (@required_trace): Remove.
15598 (@preselect): New.
15599 (&parse_args, &print_usage): -p, --preselect is a new option.
15600 (&up_to_date_p): Adjust.
15601 * bin/autoconf.in: Preselect some Autoconf macros.
15603 2001-08-04 Akim Demaille <akim@epita.fr>
15605 * tests/tools.at (autoconf --trace: user macros): Check traces on
15606 macros invoked without arguments, and macros invoked with multiple
15607 lines arguments.
15609 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
15611 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
15612 arguments.
15614 2001-08-03 Akim Demaille <akim@epita.fr>
15616 * bin/autoconf.in ($@): Work around the usual sh bug.
15617 From Nicolas Joly.
15619 2001-08-03 Akim Demaille <akim@epita.fr>
15621 Clean up the handling of the M4 builtins tracing exception.
15623 * bin/autom4te.in (Request::request): Don't complete M4 builtins
15624 trace requests.
15625 (@m4_builtins): Rename as...
15626 (@m4_builtin): this.
15627 (%m4_builtin_alternate_name): New.
15628 (&parse_args): Complete the trace requests with alternate names.
15629 (&handle_traces): Hence no longer do it here.
15630 (&trace_requests): Remove, unused.
15632 2001-08-03 Akim Demaille <akim@epita.fr>
15634 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
15635 m4_if, and m4_wrap.
15637 2001-08-03 Akim Demaille <akim@epita.fr>
15639 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
15640 (m4_divert_pop): Dump the whole diversion stack when a diversion
15641 mismatch happens.
15642 * bin/autom4te.in (&handle_output): Remember of the first
15643 occurrence of a possibly undefined macro, not the last.
15644 Complain about the possibly undefined macros in the same order as
15645 the appear in the output.
15646 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
15647 * tests/tools.at (autoconf: forbidden tokens, basic)
15648 (autoconf: forbidden tokens, exceptions): No longer sort

16066 compiler, not the preprocessor.
16067 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use

16069 the right thing.
16070 * Makefile.am (.m4.m4f): Emphasize M4 error messages and fail
16071 earlier if there are.
16073 2001-07-03 Akim Demaille <akim@epita.fr>
16075 * autoscan.in ($initfile): Remove.
16076 (&find_file): Rename as...

16102 * aclang.m4 (AC_F77_DUMMY_MAIN): New macro to detect whether a
16103 dummy alternate main is required even if the user provides her own
16104 'main'.
16105 (AC_F77_MAIN): New macro to detect whether it is possible to
16106 provide an alternate 'main' function name, using the 'main' from
16107 the Fortran libraries.
16108 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
16109 cross-language link tests can be performed successfully.
16110 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
