3 Generate package.m4 in build-dir, not srcdir.
4 * tests/Makefile.am (package.m4): Adjust target.
5 Don't redirect directly to $@.
6 (CLEANFILES): Add package.m4.
7 ($(TESTSUITE)): Depend on just-built package.m4, not the one
8 in $(srcdir).
9 When running $(AUTOTEST), search "." before searching $(srcdir).
11 Avoid a race condition that would make parallel "distclean" fail.
12 * tests/Makefile.am (distclean-generic): Replace the default,
13 automake-provided rule with an identical one, but with an additional
14 dependency on distclean-local. Simply adding the dependency would
15 cause automake not to emit the rule at all.
16 * BUGS: Building with -jN works, now.
18 Distribute git-version-gen.
19 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
20 since GNUmakefile is distributed, and requires it for dist* rules.
22 Remove two more generated files from version control.
23 * INSTALL: Remove generated file.
24 * lib/autoscan/autoscan.list: Remove generated file.
26 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
28 * GNUmakefile (PATH): Remove stray apostrophes; they become
29 part of PATH, which isn't wanted here.
31 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
33 New config files output variable `top_build_prefix'.
34 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
35 `top_build_prefix'.
36 * doc/autoconf.texi (Preset Output Variables): Document it.
37 * NEWS: Update.
38 Report by Bob Friesenhahn.
40 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
41 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
42 function, to parametrize arithmetic with expr vs. the shell.
43 Use it where possible.
44 Suggestion by Benoit Sigoure.
46 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
48 Adjust the documentation of autotest WRT atlocal.
49 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
50 when using Automake, to write a rule to produce atlocal, since it's
51 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
52 distributed, not atconfig.in.
54 2007-11-04 Eric Blake <ebb9@byu.net>
56 Update list information.
57 * README: Mention new autoconf-commit list.
58 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
60 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
62 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
64 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
66 * build-aux/.gitignore: Ignore mkinstalldirs.
68 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
70 2007-11-03 Jim Meyering <meyering@redhat.com>
72 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
73 * build-aux/git-version-gen: This syncs from coreutils.
75 Adjust the build procedure so "make check" works reliably.
76 * README-hacking: Include an extra step between "make" and
77 "make check" to ensure that the latter passes.
79 Use just-built tools, when possible.
80 * GNUmakefile (PATH): Set and export here, ...
81 (dummy): ... rather than here.
83 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
84 and Andreas Schwab <schwab@suse.de>
86 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
87 exit status bug.
89 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
91 * configure.ac (AC_PREREQ): Require version 2.60, for
92 AC_PROG_SED, AC_PROG_GREP.
94 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
95 and Jim Meyering <meyering@redhat.com>
96 and Andreas Schwab <schwab@suse.de>
97 and Eric Blake <ebb9@byu.net>
99 Document a bug in GNU Bash with compound commands and redirections.
100 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
101 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
102 workaround.
104 2007-11-03 Eric Blake <ebb9@byu.net>
106 Support m4 1.4.5 in testsuite.
107 * tests/torture.at (Define a newline): Exclude line numbers in
108 error message.
109 Reported by Ralf Wildenhues.
111 2007-11-03 Jim Meyering <meyering@redhat.com>
113 Remove automake-provided files from version control.
114 * build-aux/elisp-comp: Remove file.
115 * build-aux/install-sh: Remove file.
116 * build-aux/missing: Remove file.
117 * build-aux/mdate-sh: Remove file.
118 * build-aux/.gitignore: New file.
119 Suggestion from Ralf Wildenhues.
121 2007-11-03 Eric Blake <ebb9@byu.net>
123 Adjust version comparison to account for git snapshot numbers.
124 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
125 component separator.
126 * doc/autoconf.texi (Number processing Macros)
127 <m4_version_compare>: Document this change.
128 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
130 2007-10-30 Bruno Haible <bruno@clisp.org>
132 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
133 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
134 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
135 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
136 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
137 Suggested by Paul Eggert.
139 2007-10-28 Jim Meyering <meyering@redhat.com>
141 * README-hacking: Autoconf, Automake, and Perl are required to build.
142 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
144 2007-10-28 Jim Meyering <meyering@redhat.com>
146 README-hacking: Recommend running autoreconf -vi.
147 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
148 so that we use just-built tools when they're available.
149 Suggestions from Ralf Wildenhues.
151 2007-10-28 Jim Meyering <meyering@redhat.com>
153 Make inter-release --version output more useful.
155 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
156 which indicates that it is built using the 19th change set
157 (in _some_ repository) following the "v2.61a" tag, and that 58dd
158 is a prefix of the commit SHA1.
159 * build-aux/git-version-gen: New file.
160 * configure.ac: Run it to set the version.
161 (AM_INIT_AUTOMAKE): Don't check NEWS here.
162 * Makefile.am (dist-hook): Arrange so that .version appears only
163 in distribution tarballs, never in a checked-out repository.
164 * .gitignore: Add .version here, too. Just in case.
165 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
166 not configure.ac, now that the version number changes automatically.
168 Ensure that $(VERSION) is up to date for dist-related targets.
169 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
170 git-version-gen doesn't match $(VERSION), but only for dist targets.
172 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
174 Fix `Deep Package' failure with a configure script early in PATH
175 * tests/torture.at (Deep Package): Add `.' early in PATH.
176 Report by Jim Meyering.
178 2007-10-27 Jim Meyering <meyering@redhat.com>
180 Remove all generated files from version control.
181 * aclocal.m4: Remove.

200 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
201 and Eric Blake <ebb9@byu.net>
203 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
204 problem reported by Bruno Haible in
205 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
207 2007-10-22 Eric Blake <ebb9@byu.net>
209 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
210 preprocessor.
212 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
214 Don't check for bug in HP-UX 11.00 cpp.
215 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
216 Use -1ull rather than -1u, since that causes problems with gnulib; see
217 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
219 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

235 escaping of backslash in here-documents.
237 Fix `Deep Package' test failure on FreeBSD.

240 configure script to be found in $PATH, if the shell does not do
241 this resolution. Fixes test failure on FreeBSD.
243 Fix config header generation with AIX awk.
244 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
245 script, use helper array D_is_set, as `" 0"' does not evaluate
246 to true for AIX awk.

289 <TESTS>: Banners are no longer processed by main driver loop, so
290 we no longer need case statement.
291 (AT_BANNER): Rewrite to populate new diversion.

392 that the subpackage configure script is capable of running
393 --help=recursive in the source tree.
394 * tests/torture.at (Configuring subdirectories, Deep Package):
395 Adjust tests to expose both issues, also try invocation as

1468 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
1469 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
1470 works but the latter doesn't, then it's a valid type.
1471 This lets people use function types and so forth.
1472 For C++ there doesn't seem to be a simple solution, so leave it alone.
1473 (AC_CHECK_SIZEOF): Allow argument to be a variable.
1474 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
1475 AC_CHECK_TYPE; that wasn't documented or necessary.
1477 2007-04-11 Stepan Kasal <kasal@ucw.cz>
1479 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

1522 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
1523 checks for unsigned long long int.
1525 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
1527 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
1528 nonstandard grep R.E. escape sequences.
1530 2007-03-17 Jim Meyering <jim@meyering.net>
1532 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
1533 (Limitations of Usual Tools): Also list \< and \>, and mention that
1534 HP-UX's grep, like the one from Solaris, does not support that syntax.
1536 2007-03-09 Stepan Kasal <kasal@ucw.cz>
1538 * doc/autoconf.texi (Specifying Names): `--host' does not
1539 change the build type.
1541 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
1543 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
1544 suggests AC_CONFIG_HEADERS.
1545 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using

1551 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Fix typo "__LITLE_ENDIAN__".
1552 Problem reported by Paolo Bonzini in:
1553 http://lists.gnu.org/archive/html/autoconf-patches/2007-02/msg00024.html
1554 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
1555 universal binaries. Problem reported by Elias Pipping.
1557 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
1559 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
1560 * doc/autoconf.texi (C Compiler): Document this. There is a new
1561 extra argument ACTION-IF-UNIVERSAL.
1562 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
1563 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
1564 Reindent for sanity's sake.
1566 2007-02-24 Eric Blake <ebb9@byu.net>
1568 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
1569 copyright.
1570 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
1571 * lib/autotest/general.m4 (AT_INIT): Likewise.

1574 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1576 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
1577 status of rm so we know when it failed.
1578 If cleaning of test dir failed before running the test, warn.
1579 Output the line separator in verbose mode before the warning
1580 to make clear the warning belongs to the following test.
1582 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
1584 * doc/autoconf.texi (Parentheses): Mention problem with (( in
1585 shells.

1597 carriage return.
1598 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
1599 with traditional Awk and begin.
1600 * tests/torture.at (Limitations of Builtins): Document the problem
1601 with Bash 2.03 printf.

1605 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
1607 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect

1630 2007-01-31 Eric Blake <ebb9@byu.net>
1632 * THANKS (people): Update.
1634 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
1636 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
1637 latest version.
1638 (Shell Substitutions): Note problems with @{var:=value} etc.
1639 Add a new section for problems with @{#var} etc. Problem noted
1640 by Ralf Wildenhues. See:
1641 http://lists.gnu.org/archive/html/libtool-patches/2005-01/msg00157.html
1643 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1645 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
1646 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
1647 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
1648 substitution will still be done by the special code.
1649 Report by Jim Meyering.
1651 * doc/autoconf.texi (File System Conventions): Mention that
1652 $PATH_SEPARATOR is for the build system only.

1664 Report against Automake by Patrick Welche.
1666 2007-01-15 Stepan Kasal <kasal@ucw.cz>
1668 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
1670 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1672 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
1673 early on the reader side, drop stderr of the input to avoid
1674 `broken pipe' error output; this may happen even with shell
1675 builtin `echo' of some bash versions. Reports by Ian Macdonald
1676 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
1678 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1680 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
1681 separate items of `ac_user_opts', to avoid long lines.
1682 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
1684 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1686 * doc/autoconf.texi: Fix some typos.
1688 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
1690 Fix some wording problems noted by Paolo Bonzini in:
1691 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
1692 * doc/autoconf.texi (Signed Overflow Examples): Give more
1693 discussion about the allow_superuser_privileges example,
1694 and change it a bit to make things clearer.
1695 (Optimization and Wraparound): Clarify whether the compiler
1696 will generate an infinite loop for the example derived from
1697 Autoconf's mktime test.
1698 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
1699 Also, clarify unsigned multiplication overflow.
1701 2007-01-04 Eric Blake <ebb9@byu.net>
1703 * bin/Makefile.am (RELEASE_YEAR): New macro.
1704 (edit): Use it to supply correct copyright year to scripts.
1705 * bin/autoconf.as (version): Use it.
1706 * bin/autoheader.in ($version): Likewise.
1707 * bin/autom4te.in ($version): Likewise.
1708 * bin/autoreconf.in ($version): Likewise.
1709 * bin/autoscan.in ($version): Likewise.
1710 * bin/autoupdate.in ($version): Likewise.
1711 * bin/ifnames.in ($version): Likewise.
1713 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
1715 * doc/autoconf.texi (Integer Overflow): Revised based on today's
1716 feedback. The most important changes document what happens when
1717 you convert an out-of-range value to a signed integer type, and
1718 say that (sum < a) != (b < 0) reliably detects overflow when sum =
1719 a + b.
1721 * doc/autoconf.texi (Integer Overflow): Greatly expand and
1722 rewrite, taking notions from the recent discussion on the gcc and
1723 autoconf mailing lists; please see
1724 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
1725 and follow the many links.
1726 (Integer Overflow Basics, Signed Overflow Examples):
1727 (Optimization and Wraparound, Signed Overflow Advice):
1728 (Signed Integer Division): New sections.
1730 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
1732 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
1733 preprocessor macro arguments in traced name.
1734 * doc/autoconf.texi (Defining symbols): Document longstanding
1735 support for AC_DEFINE-ing macros with arguments, and document
1736 behavior when the same variable has multiple AC_DEFINEs.
1737 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
1738 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
1739 macros directly, giving much shorter and simpler code.
1741 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
1743 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
1744 space before "$ac_configure_args" to prevent a 'config.status
1745 --recheck' failure if ac_configure_args doesn't contain a leading
1746 space. This works around a problem with the XEmacs configure.ac,
1747 which uses the (undocumented) ac_configure_args variable
1748 inconsistently with Autoconf.
1750 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
1752 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
1753 Include <limits.h>, and use its INT_MAX to rewrite the
1754 j loop so that it does not overflow 'int'. Problem reported by
1755 Ralf Wildenhues in
1756 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
1757 Play it safe by shifting left by 1 rather than multiplying by 2,
1758 as GCC is less likely to optimize this away when the value
1759 is signed (when it assumes overflow leads to undefined behavior).
1760 Also, don't assume time_t uses two's complement.
1762 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1764 * tests/torture.at (Substitute a 2000-byte string): Avoid using
1765 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
1766 dumps core on it. Report by Tim Rice.
1768 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1770 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
1771 --disable-option-checking to --help output even when
1772 AC_PRESERVE_HELP_ORDER is not used.
1773 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
1774 --with argument, rather than argument with [-.] replaced by
1775 underscores.
1776 * NEWS: Fix typo in previous change; the news was in the
1777 wrong section.
1779 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
1781 * NEWS: Warnings are now generated by default for unknown
1782 --enable-* and --with-* options.
1783 * doc/autoconf.texi (Option Checking): Renamed from
1784 (Configure Option Checking). Tighten up the wording a bit.
1785 (External Software, Package Options): Cross-reference to Option
1786 Checking, and use this to shorten our section.
1787 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
1788 "$x" to test "x$foo" != x.
1789 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
1790 Don't warn if $enable_option_checking is "no".
1791 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
1792 ac_unrecognized_opts to the empty string.
1793 Don't echo the unrecognized opts, as this might mishandle
1794 backslashes or leading -.
1795 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
1796 usage next to the other --disable-FEATURE options in the
1797 help string.
1799 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1801 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
1802 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
1803 Print warning for unrecognized --with and --enable options
1804 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
1805 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
1806 Disable option checking when subdirs are configured.
1807 (AC_OUTPUT): If warnings are enabled, print warning about
1808 unrecognized --with and --enable options at the end of
1809 the configure output (as well as at the beginning).
1810 * doc/autoconf.texi (Option Checking): New node.
1811 Document new option warning functionality.
1813 2006-12-16 Eric Blake <ebb9@byu.net>
1815 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
1816 * NEWS: Start news for current version.
1818 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
1820 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1821 Define HAVE_GETMNTENT to 1, not to the empty string.
1822 Problem originally reported by Jochen Friedrich in
1823 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
1825 This change prompted by a problem report by Andrey Simonenko in
1826 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
1827 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
1828 object-like macros only, in the traditional portable character
1829 set.
1830 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
1831 Warn about attempts to define things that are not identifiers.
1832 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
1833 awful hack that AC_DEFINEd macro names containing parentheses.
1835 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
1837 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
1838 too drastic, even if Texinfo in theory requires it for info mode.
1840 (config.status Invocation): Renamed back from Recreating a
1841 Configuration).
1842 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
1843 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
1845 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1847 * NEWS: Version 2.61a.
1849 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1850 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1852 * NEWS: Document changes with echo and printf, and the lack
1853 of limits on the total size of multi-line values of substituted
1854 variables, and the AC_FUNC_FSEEKO fix.
1856 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
1858 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
1859 Writing configure.ac.
1860 (Autoconf Input Layout): Renamed from configure.ac Layout.
1861 (Recreating a Configuration): Renamed from config.status Invocation.
1862 (Obsolete Recreation): Renamed from Obsolete config.status Use.
1863 (acconfig Header): Renamed from acconfig.h.
1864 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
1865 (Writing Testsuites): Renamed from Writing testsuite.at.
1866 (Autom4te Cache): Renamed from autom4te.cache.
1868 * BUGS: Remove mention of VPATH problem, since it's now documented
1869 not to be a bug in the Autoconf build procedure itself, but rather
1870 a problem with the proprietary `make' programs.
1872 * doc/autoconf.texi (Build Directories): Add a cross reference
1873 to VPATH and Make.
1875 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
1876 * doc/standards.texi: Sync from gnulib.
1878 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
1879 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
1880 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
1881 generated automatically.
1883 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
1885 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
1886 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
1887 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
1889 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1891 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
1892 `CEOF$ac_eof' special marker, the awk script cannot contain a
1893 line matching `^CEOF', so this is not needed any more.
1894 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
1895 special marker in the test.
1897 2006-12-06 Stepan Kasal <kasal@ucw.cz>
1899 * tests/tools.at (autom4te preselections): Use `find -newer';
1900 remove one of the sleeps.
1902 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
1903 more readable, using ...
1904 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
1906 * doc/autoconf.texi (autoheader Invocation): Do not double-
1907 quote the parameter of `AH_BOTTOM' in the example.
1909 2006-12-05 Stepan Kasal <kasal@ucw.cz>
1911 * doc/autoconf.texi (Configuration Headers): Remove the
1912 example with multiple input files.
1913 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
1914 multiple input files.
1916 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1918 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
1919 creating the awk substitution script, handle one input line at a
1920 time, so that the maximum length of a substituted (multi-line)
1921 value is not limited by the size of the sed pattern space.
1922 The trade-off is a slightly repetitive sed script.
1923 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
1924 can only have up to 7 characters, due to Solaris 10 /bin/sed.
1925 * tests/torture.at (Substitute a 2000-byte string): Increase the
1926 test with several long lines, they should not be caught by sed
1927 limits any more.
1929 * tests/tools.at (autom4te preselections): New test, to flag
1930 entries missing from autom4te.cfg.
1931 Report by David Byron <dbyron@hheld.com>.
1933 * tests/torture.at (Substitute a 2000-byte string): Actually use
1934 AC_PROG_AWK, so the last change works as intended.
1935 (Substitute and define special characters): Likewise.
1936 (Substitute a newline): Likewise.
1938 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
1939 instead of `awk' consistently.
1940 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
1941 * tests/torture.at (Torturing config.status): Test both the
1942 result of AC_PROG_AWK and plain awk.
1943 (Substitute a 2000-byte string): Likewise.
1944 (Substitute and define special characters): Likewise.
1945 (Substitute a newline): Likewise.
1947 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
1949 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
1950 can be assigned to a function pointer. Problem reported by
1951 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
1952 part of a patch by Ralf Wildenhues in that same bug report.
1954 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
1956 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
1957 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
1959 2006-12-01 Eric Blake <ebb9@byu.net>
1961 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
1962 cross-compiling from cygwin to mingw.
1963 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
1964 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
1965 to lib/autoconf/c.m4.
1967 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1969 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
1970 string for more reliable failure. Wrap the entire test that
1971 causes the broken Solaris printf to dump core, in a subshell,
1972 so the segmentation fault message is reliably suppressed.
1973 Fix shell expansion errors by using /usr/ucb/echo always;
1974 avoid an error on systems without it by another subshell.
1975 Avoid m4 expansion of `$1'. Set the zeroth argument of the
1976 subshell-$as_echo to `as_echo', for better error message.
1978 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1980 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
1981 `BASH_SOURCE' contain a newline, set them to empty, as they may
1982 not be unset.
1984 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
1986 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
1987 years and is too hard to maintain now. The last straw was
1988 reported by Jerker Baeck in
1989 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
1990 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
1991 * doc/autoconf.texi (Particular Functions): Move
1992 AC_FUNC_SETVBUF_REVERSED from here...
1993 (Obsolete Macros): ... to here. Say that it does nothing now.
1994 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
1995 Turn into (almost) a no-op.
1997 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
1998 (AC_C_VOLATILE):
1999 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
2000 These macros are obsolescent and new applications shouldn't need them.
2001 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
2002 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
2003 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
2004 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2005 (AC_FUNC_VPRINTF): Likewise.
2006 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
2007 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
2008 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
2010 * doc/autoconf.texi (Setting Output Variables): Mention that
2011 @VAR1@VAR2 has unspecified behavior. Problem reported by
2012 Ralf Wildenhues.
2013 * NEWS: Mention this.
2015 * Makefile.am: Put only a single '#' into the copyright notice,
2016 so that it's also present in the output file. Standardize wording
2017 in makefile copyright notices to match GNU coding standards.
2018 * bin/Makefile.am: Likewise.
2019 * doc/Makefile.am: Likewise.
2020 * lib/Makefile.am: Likewise.
2021 * lib/freeze.mk: Likewise.
2022 * lib/autoconf/Makefile.am: Likewise.
2023 * lib/autoscan/Makefile.am: Likewise.
2024 * lib/autotest/Makefile.am: Likewise.
2025 * lib/m4sugar/Makefile.am: Likewise.
2026 * man/Makefile.am: Likewise.
2027 * tests/Makefile.am: Likewise.
2028 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
2029 one-line file.
2031 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2033 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
2034 in the sed script that mangles the awk script: delete up to the
2035 first exclamation mark only.
2036 * tests/torture.at (Substitute and define special characters):
2037 Test '!' too.
2039 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2041 Rewrite config files generation: avoid quadratic growth in
2042 the number of substituted variables by using awk instead of sed
2043 for the bulk of the substitutions.
2044 * NEWS: Mention this.
2045 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
2046 forbidden in the output (and thus input) file.
2047 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
2048 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
2049 generate just one large awk script for substitutions,
2050 eliminating much of the earlier complexity, while adding some
2051 new complexity. Only expand the substitution templates at
2052 configure time, for smaller configure script size. If
2053 _AC_SUBST_FILES are used, test 'awk' for working getline support
2054 at config.status time. If absent, interpolate through the
2055 shell. The awk script was written with much help
2056 from Paolo Bonzini and Paul Eggert.
2057 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
2058 (_AC_SED_FRAG_NUM): Likewise.
2059 (_AC_SUBST_CMDS): Renamed from...
2060 (_AC_SED_CMDS): ...this.
2061 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
2062 * tests/torture.at (Substitute a 2000-byte string): Also
2063 substitute a line with 1000 words, and a variable with several
2064 long lines.
2065 (Substitute and define special characters): Test awk special
2066 characters, and put substitution input strings `@foo@' in the
2067 output, to test that no recursion happens; test several other
2068 combinations from Paolo Bonzini.
2070 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
2072 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
2073 that replaced echo with AS_ECHO where this wasn't necessary.
2074 Problem reportd by Ralf Wildenhues.
2075 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
2076 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
2077 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
2079 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2081 * lib/freeze.mk (GREP): Removed, no need to initialize this.
2083 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
2085 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
2086 that traditional Awk lacks 3-arg "split". It has it.
2087 Mention that FS must be a single character, and a few other
2088 99-byte limits of traditional Awk.
2089 Mention that if (i in a) doesn't work with traditional Awk.
2091 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
2093 * tests/autotest.at (BSx641-newline in command):
2094 (BS-BS-newline in command, BSx640-newline in command):
2095 (Newline-CODE-BS-newline in command):
2096 (Single-quote-BS-newline in command):
2097 (Single-quote-newline-BS-newline in command):
2098 Use printf '%s\n' instead of echo, for portability to hosts
2099 where echo interprets backslashes. This will break on hosts
2100 that lack printf, but for now let's assume all such hosts
2101 are dead (if not, we should get reports of test failures).
2103 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2105 'echo' has some portability problems, when given a first argument
2106 with a leading '-', or when given any argument containing '\'.
2107 Avoid using 'echo' in these cases.
2108 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
2109 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
2110 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2111 * lib/autotest/general.m4 (AT_INIT): Likewise.
2112 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
2113 argument might be unportable.
2114 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
2115 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

2117 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
2118 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
2119 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
2120 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):

2132 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
2133 * bin/autoconf.as: Redo verbose flag implementation, as the old
2134 scheme wouldn't work with AS_ECHO.
2135 * lib/autotest/general.m4 (AT_INIT): Likewise.
2136 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
2137 Don't use ECHO_T, since ECHO_N is now reliable.
2138 * lib/autotest/general.m4 (AT_INIT): Likewise.
2139 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
2140 rather than using a here-document to put the script into a file.
2141 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
2142 use AS_ECHO.
2143 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
2144 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
2145 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
2146 bug, but we might as well stop using ECHO_N and ECHO_C internally.
2147 * lib/autotest/general.m4 (AT_SETUP): Likewise.
2148 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
2149 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2150 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
2151 operand, as AS_ECHO requires. Avoid double file name expansion.
2152 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
2153 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
2154 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
2155 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
2156 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
2157 Double-quote strings that would otherwise contain M4 comments.
2158 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
2160 * configure.ac (AC_INIT): Bump to 2.61a.
2161 * NEWS: Likewise.
2163 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2165 Version 2.61.
2167 * configure.ac (AC_INIT): Bump to 2.61.
2168 * NEWS: Likewise.
2170 * tests/autotest.at (Macro with backslash in a test title):
2171 Comment out for now, as this tests neither fails nor passes
2172 reliably. Problem reported by Ralf Wildenhues.
2174 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
2176 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
2177 in previous change, which caused test failures.
2179 2006-11-16 Stepan Kasal <kasal@ucw.cz>
2181 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
2182 code for --enable, --disable, --with, and --without to...
2183 (_AC_INIT_PARSE_ENABLE): ... a new macro.
2184 * doc/autoconf.texi (Package Options):
2185 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
2187 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
2189 Import these changes from config via gnulib:
2191 2006-11-15 Ben Elliston <bje@gnu.org>
2193 From Josselin Mouette <joss@debian.org>:

2248 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
2250 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
2251 benefit of platforms like Solaris+GCC where it is common to have a
2252 non-working g++ installation.
2254 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2255 and Joel E. Denny <jdenny@ces.clemson.edu>
2256 and Paul Eggert <eggert@cs.ucla.edu>
2258 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
2259 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
2260 ./micro-suite.
2262 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2264 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
2265 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
2266 Imported from a similar patch to gnulib by Bruno Haible.
2268 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2270 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

2278 Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
2279 Matthew Woehlke.
2281 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2283 * tests/torture.at (Configuring subdirectories): Do not skip
2284 Automake 1.10 nor future Automake 11.1 (sic).
2286 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
2287 and Stepan Kasal <kasal@ucw.cz>
2289 Handle special characters in test case titles correctly.
2290 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
2291 properly.
2292 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
2293 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
2294 argument. Extend to check titles printed by ./micro-suite and
2295 ./micro-suite -l and the title in micro-suite.log.
2296 (Backquote in a test title,
2297 Single-quote in a test title,
2298 Double-quote in a test title): Don't expect failure anymore.
2299 (Backslash in a test title): Put a non-whitespace character after the
2300 backslash so that Bourne shells might actually see it as an escape
2301 sequence.
2302 (Brackets in a test title,
2303 Pound in a test title,
2304 Comma in a test title,
2305 Quoted Macro in a test title,
2306 Macro in a test title,

2309 Macro with double-quote in a test title,
2310 Macro with backslash in a test title): New tests expected to fail.
2311 * tests/torture.at (#define header templates): M4-quote this title in
2312 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
2313 The visible effect was a stray [] in the testsuite output.
2315 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2317 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
2318 `trap ... 0' inside a function, for AIX sh.
2320 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
2322 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
2323 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
2324 5363) simply issues a warning when dividing by zero at compile
2325 time. Problem reported by Elias Pipping.
2327 2006-10-26 Eric Blake <ebb9@byu.net>
2329 * THANKS: Update.
2330 * doc/autoconf.texi (Evaluation Macros): Improve the example to
2331 show effect on macros that expand with commas.
2332 Reported by Joel E. Denny.
2334 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
2335 Also work with M4 1.4.8.
2337 2006-10-25 Paul Eggert <eggert@cs.ucla.edu>
2339 * doc/autoconf.texi (Slashes): Document Tru64 4.0 bug reported by
2340 Jim Meyering.
2342 2006-10-25 Stepan Kasal <kasal@ucw.cz>
2344 * tests/tools.at (autom4te --force): New test, verifies that
2345 `--force' always rewrites the output file.
2347 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
2349 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm
2350 needs operands on NetBSD 2.0.2. Problem reported by Bruno Haible.
2352 2006-10-24 Stepan Kasal <kasal@ucw.cz>
2354 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
2356 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
2358 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2359 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
2360 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
2361 reported by Nelson H. F. Beebe for Coreutils 6.4.
2363 * tests/tools.at (autoconf --trace: user macros): Remove test
2364 for tracing multiline macros, since m4 1.4.7a uses a different
2365 way to number lines. Problem reported by Ralf Wildenhues.
2367 2006-10-24 Stepan Kasal <kasal@ucw.cz>
2369 * bin/autom4te.in (handle_m4): Do not redirect stdin to
2370 /dev/null since the heuristics for interactive behaviour was
2371 fixed in CVS m4.
2373 * bin/autom4te.in: With --force, always refresh the output

2395 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
2396 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
2398 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2427 looking for special shell characters.
2428 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
2429 macro defined by AS_VAR_PUSHDEF before passing it as a
2430 parameter.

2441 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
2443 (Imported from Automake.)
2444 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
2445 which incorrectly sets the mode of an existing destination
2446 directory. In some cases the unpatched install-sh could do the
2447 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
2448 system. We hope this is rare in practice, but it's clearly worth
2449 fixing. Problem reported by Alex Unleashed in
2450 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
2451 Also, don't bother to check for -m bugs unless we're using -m;
2452 suggested by Stepan Kasal.

2461 Report from Bruno Haible.
2463 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

2472 Import this change from Gnulib:
2474 2006-09-16 Karl Berry <karl@gnu.org>
2475 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,

2498 2006-10-13 Stepan Kasal <kasal@ucw.cz>
2500 * doc/autoconf.texi (Autoheader Macros): Warn that the text
2501 added to the template can get mangled.
2503 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2505 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
2506 include the default headers, and redefine obstack_chunk_alloc
2507 and obstack_chunk_free. Fixes false failure with glibc.
2509 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
2511 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

2521 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
2523 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
2524 the NonStop platform.

2526 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
2528 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
2529 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
2530 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
2531 Use a better substitute, by inspecting the output of "ls"
2532 rather than just using ":".
2533 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
2534 rather than AS_EXECUTABLE_P, since we needn't worry about
2535 non-regular files here.
2537 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
2538 due to configuration hassles with this. See Tonya Underwood's report
2539 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

2548 2006-10-11 Stepan Kasal <kasal@ucw.cz>
2550 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
2551 initialization which is not inherited through the environment
2552 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
2553 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
2555 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
2557 * doc/autoconf.texi (Limitations of Usual Tools): Describe
2558 problems with mkdir -p -m.
2560 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
2562 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
2563 comment about ac_cpp_err; it was incorrect, and anyway
2564 ac_cpp_err is being removed below.
2565 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
2566 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
2567 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
2568 nobody uses it.
2569 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
2570 with werror_flag and conftest.err and so forth. This is more
2571 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
2572 and anyway the user shouldn't normally want to see this gorp logged.
2573 Problem reported by Ralf Wildenhues.
2574 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
2575 empty, not 'no', since the rest of the code uses 'test -z'.
2577 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
2579 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2580 Use a single call to AC_DO_TOKENS rather than multiple, for
2581 efficiency.
2582 (_AC_LINK_IFELSE): Test that resulting file is executable.
2583 Problem reported by mwoehlke in
2584 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
2586 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
2587 than creating a file to use with test -x; this is much faster.
2589 2006-10-02 Bruno Haible <bruno@clisp.org>
2591 * lib/autom4te.in (Automake-preselections): Add
2592 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
2594 2006-09-27 Stepan Kasal <kasal@ucw.cz>
2596 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
2597 standard error, `experr' should be used, not `expout'.
2599 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2601 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
2602 fseeko testing program twice; just use the earlier result.
2603 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2604 Set cache var to 'unknown' (not 'no') if leaving the macro unset
2605 still doesn't let the program compile.
2606 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
2607 failed.
2609 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
2610 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
2611 include it, without including anything else.
2612 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
2613 expressions.
2614 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
2616 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2618 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
2619 `error.h', and include it, for a `error_at_line' prototype.
2620 Use a nonempty format string in the link test.
2621 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
2622 for a declaration of wait3.
2624 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2626 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
2627 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
2628 can apply to constants too, and that it checks for macro defns.
2629 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
2630 and simply cast the identifier to void. This handles structure
2631 values. Problem reported by Ralf Wildenhues.
2632 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
2634 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2636 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
2637 structure, and function symbols.

2656 present.
2657 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add

2688 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
2689 --error-output, to avoid warnings with M4 2.0.
2691 2006-09-19 Stepan Kasal <kasal@ucw.cz>
2693 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

2704 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
2705 mistaken comment: the path has to be relative; do not use
2706 the path at runtime.
2708 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2710 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

2714 for both changes.
2715 * doc/autoconf.texi (Setting Output Variables): Fix example to

2720 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
2721 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
2722 for the existence of the directory at configure-time. That's
2723 too late, anyway. Problem reported by Stefan Seefeld.
2725 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
2726 7.1.4 /usr/bin/posix/sh described by Tim Rice in
2727 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
2729 2006-09-11 Stepan Kasal <kasal@ucw.cz>
2731 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
2732 works with GNU M4 1.4.3 again; make the normalized form
2733 match the current m4 message; fix the description.

2736 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
2738 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
2739 to catch glibc bug 2821
2740 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
2742 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
2743 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
2744 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
2745 assume C89.
2747 2006-09-08 Stepan Kasal <kasal@ucw.cz>
2749 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

2767 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
2768 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
2769 accept files with extension `.f'. For consistency, also prefer
2770 xlf over f77.
2771 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
2772 from last patch.

2792 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
2793 except the first two arguments are reversed.
2794 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
2795 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
2796 caches nor outputs a diagnostic. Suggested by Bruno Haible.
2797 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
2798 equivalent to the old AC_COMPUTE_INT.
2799 (AC_COMPUTE_INT): No longer caches or reports. New signature.
2800 All uses changed to AC_CACHE_CHECK_INT.
2801 * tests/base.at (AC_CACHE_CHECK_INT): New test.
2802 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
2804 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
2806 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
2807 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
2808 programs should use their Gnulib counterparts.

2811 obsolete macros with uses of non-obsolete macros.

2835 simplify the code.
2837 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
2839 Fix Lex library problem reported to us by Julio Garvia.
2840 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
2841 for the default, which the user can override.
2842 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
2843 deal with LEXLIB.
2844 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
2845 didn't work if some values were cached but not others. Test for
2846 broken lex libraries like native ia64-hp-hpux11.22; see
2847 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
2848 work around the problem by preferring an empty LEXLIB to -lfl or
2849 -ll. Let the user set LEXLIB='' to indicate no library needed.
2851 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
2852 * README: Likewise.
2853 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
2855 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>

2954 * doc/autoconf.texi (Particular Programs): Mention that
2955 @INSTALL@ and @MKDIR_P@ may vary for different output files.
2956 Reported by Alexandre Duret-Lutz.
2958 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
2960 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
2961 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
2962 Bill Northcott in
2963 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
2965 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>
2967 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to

2977 -Wundef -Werror". Problem reported by David Fang in
2978 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
2979 * doc/autoconf.texi (Header Templates, Default Includes):
2980 (Particular Functions, Generic Functions, Header Portability):
2981 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
2982 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):

2994 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
2995 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
2996 this.
2998 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
3000 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
3001 problems with arg script text that doesn't end in newline, and
3002 with '-e a...'. Problems reported by Ralf Wildenhues.
3004 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
3006 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
3007 check for libXt by a check for libX11.
3009 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3012 to last change.
3014 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3016 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
3017 --help' should mention that `--version' outputs configuration
3018 settings. Report by Bruno Haible.
3020 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
3022 Fix test suite failures reported by Pierre in
3023 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
3024 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
3025 the compiler created a file "b.out" when it didn't create anything
3026 at all.
3027 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
3028 Discard stderr too, when invoking the test script.

3032 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
3033 in the restoring of the werror flag.
3035 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>

3038 less skeptical about "volatile", after discussion with
3039 Bruno Haible on bug-gnulib.
3040 (Limitations of Usual Tools): Warn about sed stripping
3041 leading white space from text. From Bruno Haible.
3043 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
3045 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
3046 compiler complains about it, even if things works after the
3047 complaint. Problem reported by Peter O'Gorman.
3049 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
3050 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
3051 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
3053 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
3055 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
3056 after -R regardless of host. Patrick Welche reports that this
3057 fixes things on NetBSD 3.99.
3059 * NEWS: Recommend M4 1.4.5.
3060 * README: Likewise.
3061 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
3062 * tests/tools.at (autom4te cache): Update wording of diagnostic
3063 to match M4 1.4.5.
3065 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3067 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
3068 under AC_C_VOLATILE.
3069 (Volatile Objects): Be a little less skeptical about what
3070 "volatile" means. Derived from thoughts by Ben Pfaff in
3071 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
3073 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3075 * doc/autoconf.texi: Fix some typos.
3077 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3079 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3080 more globally, since the 2006-06-30 patch didn't suffice. Problem
3081 reported by Keith Marshall. Also, don't bother with builddir2,
3082 since it shouldn't be needed any more.
3084 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
3086 * doc/autoconf.texi (Generic compiler characteristics):
3087 Document AC_COMPUTE_INT. Fix wrong statements on Default
3088 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.

3093 AC_COMPUTE_INT.
3095 * NEWS: Document change.
3097 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
3099 * doc/autoconf.texi (Volatile Objects): New section.
3101 * NEWS: Document previous change.
3103 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
3105 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
3106 Require that long long int be at least 64 bits wide. C99 requires
3107 this and enough programs depend on it so we should check for it.
3108 Bruno Haible reports in
3109 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
3110 that long long int is 32 bits wide with some nonstandard compilers.
3111 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
3113 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
3115 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3116 to a nonexistent file, so that we don't have to worry about
3117 a local site configuration that doesn't use /usr/local.
3118 Problem reported by Keith Marshall in
3119 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
3121 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
3123 * doc/autoconf.texi: Be more consistent about using @acronym with
3124 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
3125 quite right (it talked about "OSF/Tru64", even though the
3126 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
3127 and it even mentioned "OSF 4"!) and at this point there's little
3128 reason to talk about OSF any more, since it died in 1994.
3129 (Specific Compiler Characteristics): Simplify example of
3130 negative-size array.
3131 (File Descriptors): Reorder to make the text flow better.
3132 Remove joke about "appreciate the various levels"; I didn't get it.
3133 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
3134 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
3135 (File Descriptors, Limitations of Usual Tools):
3136 Tone down the advice against renaming or removing open files.
3137 (Limitations of Usual Tools): Add a new section, on 'rm'.
3139 2006-06-26 Stepan Kasal <kasal@ucw.cz>
3141 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
3142 -lXt in LIBS, idea from Karsten Hopp; this was due since
3143 this change:
3145 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3146 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3147 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3148 (which belong to Xt, not X itself). See Debian bug 327655.
3150 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3152 * configure.ac (AC_INIT): Bump to 2.60a.
3153 * NEWS: Update.

3161 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3163 * config/texinfo.tex: Sync from upstream.
3165 * bin/autom4te.in (handle_traces): Transform the `@S|@'
3166 quadrigraph correctly in traces.
3168 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
3169 Fix typos.
3171 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
3172 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
3173 not defined.
3174 * doc/autoconf.texi (Changed Directory Variables): New node,
3175 to document the whole `datarootdir' business a bit better.
3176 * NEWS: Update.
3177 * tests/torture.at (datarootdir workaround): Extend test.
3178 Prompted by report by Alexandre Julliard.
3180 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
3182 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
3183 when using default mode of IBM C 6 for AIX. Problem and two-line
3184 fix reported by Larry Jones.
3186 2006-06-22 Alexandre Julliard <julliard@winehq.org>
3188 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
3189 about literal '${datarootdir}' if a definition is found in the
3190 output file.
3192 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
3194 * NEWS: Use "M4" rather than "m4" when appropriate.
3195 Problem reported by Eric Blake.
3196 * doc/autoconf.texi: Likewise.
3197 Use @acronym around BSD, GCC, and GNU when appropriate.
3198 (Why GNU M4): Renamed from "Why GNU m4".
3199 (Redefined M4 Macros): Mention that Posix
3200 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
3201 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
3202 to int.
3204 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3206 * bin/autom4te.in (handle_output): Do not forbid the empty
3207 pattern.
3208 * tests/tools.at (autoconf: the empty token): New test.
3210 2006-06-20 Stepan Kasal <kasal@ucw.cz>
3212 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
3213 calls, so that we do not care whether they are LIFO or FIFO;
3214 in the m4_wrap, do not check which diversion is the topmost
3215 one, just check that the stack is balanced at the end.
3216 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
3217 base diversion forever--pop the previous diversion before
3218 opening the new one; consequently, remove the m4_wrap call.
3219 * lib/autotest/general.m4 (AT_INIT): Likewise.
3220 * tests/m4sugar.at: Do not use
3221 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
3223 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
3224 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3226 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
3227 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
3228 Rework example of m4wrap token-pasting trouble so that it doesn't
3229 care whether it's LIFO or FIFO.
3230 Fix some "contrary to"s that are awkward in English.
3232 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3234 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
3235 to `yes' instead of `int$1_t' if the type is found, for more
3236 consistent configure output (where $1 is the number of bits).
3237 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
3238 Suggested by Bruno Haible.
3240 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
3241 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
3242 with system headers. Report by Bruno Haible.
3244 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3246 * config/config.guess, config/config.sub: Sync from upstream.
3248 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
3249 in order to avoid picking up an older installed frozen m4sh.m4f.
3250 Besides an outdated shell startup, this could have been created
3251 by an earlier M4 version with incompatible frozen file format.
3253 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
3255 * README: Recommend m4 1.4.4 instead of 1.4.3..
3256 * doc/autoconf.texi: Likewise.
3257 (Special Chars in Names): Say that $(.FOO) is portable, as
3258 suggested by Stepan Kasal.
3259 (Installation Directory Variables, Build Directories):
3260 (Automatic Remaking, Subdirectories, Fortran Compiler):
3261 (Making testsuite Scripts, Defining Directories):
3262 Quote variable usages better.
3263 (Making testsuite Scripts): Add clean-local rule to makefile
3264 snippet, by Eric Blake.
3265 (Installation Directory Variables): Fix table item font.
3266 Reword slightly to clarify. Generalize advice about
3267 not using special characters to include all file-related
3268 vars, not just VPATH.
3269 (Special Chars in Variables): Warn about special characters in
3270 $(srcdir) too.
3271 (Assignments): Clarify default-value example as suggested by
3272 Ralf Wildenhues in
3273 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
3274 (Special Shell Variables): Note leading ./ or ../, as suggested
3275 by Eric Blake.
3276 (Limitations of Builtins): Under cd, warn about CDPATH.
3277 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
3278 Ralf Wildenhues.
3280 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3282 * doc/autoconf.texi (Configuration Actions): Remove duplicate
3283 `@var', for texi2html.
3284 (Systemology): Some more word wrapping, for DVI output.
3285 (autom4te Invocation): The short option for `--melt' is `-M',
3286 not `-m'.
3288 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
3290 * doc/autoconf.texi: More formatting and English tweaks,
3291 many suggested by Ralf Wildenhues.
3292 Reword to avoid "@code{...}'s" and the like, since it's ugly
3293 with Emacs info mode. discontents -> woes.
3294 Put a few "will"s back. time stamp -> timestamp.
3295 side-effect -> side effect.
3297 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
3299 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
3300 Warn about $@ not persisting. Problem reported by Julien Danjou in
3301 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
3302 (Special Chars in Names): Renamed from Leading _ in Macro Names.
3303 Mention other special chars, too.
3305 2006-06-14 Eric Blake <ebb9@byu.net>
3307 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
3309 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
3311 * doc/autoconf.texi: Some systematic minor improvements, as
3312 follows. Use "makefile" when talking about makefiles
3313 generally (which might be named "makefile" or "Makefile" or even
3314 "foo.mk"), "Makefile" when talking about a specific makefile
3315 called "Makefile". This unclutters the text from weird quotes
3316 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
3317 values" rather than "@var{foo}s" and similar constructs containing
3318 "}s". Use "Make rules" rather than "Makefile rules". Minor
3319 English-language improvements. Change the prefix "sub-" to "sub"
3320 and "re-" to "re".
3321 Put blank lines around examples more consistently.
3322 Avoid "rather" and "very" as intensifiers.
3323 Avoid "will" as an auxiliary.
3324 (Limitations of Make): Split this node into....
3325 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
3326 (Leading _ in Macro Names, Backslash-Newline-Newline):
3327 (Backslash-Newline Comments, Long Lines in Makefiles):
3328 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
3329 (obj/ and Make, make -k Status, VPATH and Make):
3330 (VPATH and Double-colon, $< in Explicit Rules):
3331 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
3332 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
3333 New nodes, resulting from splitup of Limitations of Make.
3334 All cross-references changed. Raise the top node from
3335 a section to a chapter, and all subnodes accordingly.
3336 Redo the introductory wording to match the new organization.
3337 (Installation Directory Variables): Use an example that is
3338 closer to what Autoconf actually does. Mention that VPATH's
3339 value should not contain metacharacters or white space.
3340 (Fortran Compiler): Fix a VPATH bug in an example.
3341 (Leading _ in Macro Names): Mention that this problem is no longer
3342 of practical concern.
3343 (VPATH and Make): Reword the advice to make it clearer
3344 that Autoconf and Automake support VPATH in non-GNU make, but
3345 many packages have bugs in this area.
3346 ($< in Explicit Rules): Refer to Build Directories rather
3347 than using a (non-VPATH-safe) example.
3348 (Automatic Rule Rewriting): Mention the sort of disaster that
3349 can ensue with Solaris-style rule rewriting with VPATH.
3351 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3353 * doc/install.texi (Compilers and Options): Weaken the
3354 suggestion to use GNU make for VPATH builds.
3356 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
3357 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
3359 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
3360 in regular expression.
3362 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3364 * doc/autoconf.texi (Installation Directory Variables):
3365 Drop extra @samp from `@table @samp' item.
3366 (Limitations of Usual Tools): Comment fix.
3367 Do not nest @samp just to point to other table items.
3368 (Writing testsuite.at) <AT_CHECK>: The second argument to
3369 `@dvar' is already @samp'ed.
3370 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
3371 do not use @var in the second argument.
3373 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
3375 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
3376 $as_shell.exe too. Problem reported by Andreas Buening in
3377 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
3379 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3381 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
3382 `unused variable' compiler warning, for `-Wall -Werror'.
3383 Reported by Jaap Haitsma in
3384 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
3386 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
3388 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
3389 case the compiler dumps core. Problem reported for
3390 OpenServer 5.0.7 by Tim Rice in
3391 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
3392 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3393 Likewise.
3395 2006-06-06 Tim Rice <tim@multitalents.net>.
3397 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
3398 "ERROR" only shows up in "make check" output if there is an
3399 error.
3401 2006-06-06 Eric Blake <ebb9@byu.net>
3403 * tests/tools.at (automatically allowed tokens): Fix typo.
3405 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3407 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
3409 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
3410 typically overflows on x86 CPUs, even though the C standard
3411 requires otherwise.
3413 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3415 * configure.ac (AC_INIT): Bump to 2.59e.
3416 * NEWS: Update.
3418 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3420 Version 2.59d.
3422 * config/texinfo.tex: Sync from upstream.
3424 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
3425 seen, invoke libtoolize with `--ltdl' argument.
3426 * lib/autom4te.in (Autoreconf-preselections): Adjust.
3427 * NEWS: Update.
3428 Suggested by Eric Blake.
3430 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3432 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
3433 reported by Ralf Wildenhues.
3434 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
3436 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3438 * THANKS: Update.
3440 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3442 * doc/autoconf.texi: Modernize some of the references to Solaris.
3444 2006-06-05 Stepan Kasal <kasal@ucw.cz>
3446 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
3447 message issued by AC_REQUIRE.
3448 * tests/m4sugar.at: Check m4_require's error message.
3449 * tests/base.at: Check AC_REQUIRE's error message.
3450 * tests/local.at (AT_CHECK_M4): New macro, almost identical
3451 to...
3452 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
3453 AT_CHECK_M4.
3454 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
3455 `expout' as the last parameter.
3456 * tests/tools.at: Adapt to the above change.
3458 2006-06-04 Stepan Kasal <kasal@ucw.cz>
3460 * doc/autoconf.texi (Limitations of Usual Tools): Correct
3461 information about race-free implementations of mkdir.
3463 2006-06-04 Eric Blake <ebb9@byu.net>

3466 * bin/autoconf.as (Usage): Likewise.
3467 * bin/autom4te.in (help): Likewise.
3468 * doc/autoconf.texi (autom4te Invocation): Likewise.
3470 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
3472 * NEWS: GNU make now recommended for VPATH builds.
3473 Mention that some macros are now documented to be obsolescent.
3474 * doc/autoconf.texi:
3475 Prefer "current" to "modern" to describe
3476 currently-used (albeit perhaps old-fashioned) hosts.
3477 Mention which ancient features no longer need to be worried about.
3478 setgid -> set-group-ID
3479 setuid -> set-user-ID (these are the Posix terms)
3480 Fix some misuses of "only".
3481 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
3482 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
3483 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
3484 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
3485 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
3486 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
3487 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
3488 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
3489 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
3490 Mention that these macros are obsolescent.
3491 (Installation Directory Variables): shall -> should
3492 (File Descriptors): Mention that 0, 1, 2 might get reopened.
3493 Mention that it's now safe to use 3 and 4.
3494 (Limitations of Usual Tools): cp -r is now specified by Posix.
3495 Omit longwinded and obsolescent discussion of cp -f.
3496 Modernize discussion of expr, ls.
3497 (Limitations of Make): Modernize discussion of VPATH builds.
3498 Mention $? as a workaround in some cases.
3499 * doc/install.texi (Basic Installation):
3500 Mention "./configure; make; make install" first. Be more
3501 specific about why this file is generic. Remove unnecessary
3502 parens. Remove misleading "only". Remove obsolete advice
3503 about csh. Don't say "configure" takes awhile; say it
3504 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
3505 and CC=c99 rather than CC=c89, as these are blessed by current
3506 Posix. Recommend GNU make if doing a VPATH build.
3508 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
3510 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
3511 examples involving shell prompts.
3513 2006-06-02 Stepan Kasal <kasal@ucw.cz>
3514 and Paul Eggert <eggert@cs.ucla.edu>
3516 * doc/autoconf.texi (Here-Documents): Add details about the
3517 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
3518 use "here-documents" instead of "here documents".
3520 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3522 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
3524 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
3526 * doc/autoconf.texi (File System Conventions): Warn about ":"
3527 anywhere in directory names.
3529 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
3531 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
3532 about quoting the case statement, just in case.
3533 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
3534 was fixed in ksh93g; reported by Ralf Wildenhues.
3536 2006-05-31 Stepan Kasal <kasal@ucw.cz>
3538 * doc/autoconf.texi (System Services): Do not document
3539 overriding EXEEXT via ac_cv_exeext=ext.
3540 (Particular Programs) <AC_PROG_MKDIR_P>:
3541 Document that ${MKDIR_P} understands --.
3542 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
3543 comment.
3545 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3547 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
3548 argument with leading hyphen. Problem reported by Paul Eggert.
3550 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3552 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
3553 about quoting ac_try: quote all of it, if any of it seems suspicious.
3554 This means we don't have to worry about ${ or sed any more.
3555 Also, double-quote the case statement, to work around misuses via
3556 underquoting as reported by Ralf Wildenhues in
3557 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
3558 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
3559 undocumented and dangerous macro.
3560 Problem reported by Ralf Wildenhues in
3561 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
3563 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3565 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
3566 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
3567 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
3569 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3571 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
3572 since evidently some packages rely on the old, broken behavior.
3573 Problem reported by Ralf Wildenhues in
3574 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
3575 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
3576 pre-2006-05-26 definitions, but leave in the comments that
3577 these macros are dangerous and should not be used.
3578 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
3579 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
3580 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
3581 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
3582 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
3584 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
3586 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
3587 the use of 'tr', since this is our only use of 'tr'.
3589 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3590 and Paul Eggert <eggert@cs.ucla.edu>
3592 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
3593 Don't assume 'grep' works on long lines, since AIX grep doesn't.
3595 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3597 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
3598 the output file in the `${datarootdir}' test.
3600 2005-05-28 Stepan Kasal <kasal@ucw.cz>
3601 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3603 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
3604 mention of `datarootdir' in the input file(s), but literal
3605 `${datarootdir}' in the output file, and we haven't warned yet,
3606 then warn as well: the user may have (erroneously) used
3607 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
3608 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
3609 * tests/torture.at (datarootdir workaround): Extend this test.
3610 * NEWS: Update.
3612 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3613 and Paul Eggert <eggert@cs.ucla.edu>
3615 * doc/autoconf.texi (autoheader Invocation): The first argument to
3616 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
3617 alternatives and clear up the language a bit.
3619 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
3621 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
3622 ac_config_guess, ac_config_sub, ac_configure.
3623 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3624 Fix typo that prevented an unnecessary space from being removed.
3625 Problems reported by Ralf Wildenhues in:
3626 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
3628 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
3630 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
3631 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
3632 Don't use the term "thread-safe" to talk about mkdir race
3633 conditions, since the problem is more a process than a thread
3634 issue. Problem reported by Stepan Kasal in:
3635 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
3636 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
3637 the test for 'install' more closely. Look at MKDIR_P first.
3638 Look in the PATH, and at /opt/sfw/bin.
3639 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
3640 Don't bother to try mkdir -p, since we already check mkdir --version;
3641 just look at the version number. (There's no easy way to check
3642 for race-free implementations.)
3643 * tests/tools.at (autoconf: subdirectories): Adjust to above
3644 changes, since MKDIR_P now might end in "/mkdir -p".
3646 * doc/autoconf.texi (autoheader Invocation): Mention that the
3647 first arg of AC_DEFINE_UNQUOTED must be a literal.
3648 Problem reported by Ben Pfaff in
3649 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
3651 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
3652 * doc/autoconf.texi (Special Chars in Variables): New section.
3653 (Preset Output Variables): Warn about special chars in CPPFLAGS.
3654 (Installation Directory Variables): Quote $(datadir) better.
3655 (Limitations of Builtins): Describe some of eval's trickiness.
3657 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
3658 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
3659 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
3660 in front of every arg, not just trailing args. Quote apostrophes.
3661 (_AC_EVAL_ECHO): New macro.
3662 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
3663 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
3664 removed.
3665 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
3666 exposed by quoting of eval argument. Put the command on line line
3667 so it logs better.
3668 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
3669 (_AC_PATH_X, AC_PATH_X): Quote more safely.
3670 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
3671 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
3672 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
3673 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
3674 Use eval more safely.
3675 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
3676 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
3677 to be replaced.
3678 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
3679 lines, exposed by quoting of eval argument.
3681 2006-05-26 Stepan Kasal <kasal@ucw.cz>
3682 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3684 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
3685 initialization of `ac_cv_exeext', do not override it if it was
3686 already set, unless it was set to `no', for compatibility with
3687 Autoconf-2.13, and comment this.
3688 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
3689 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
3690 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
3691 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
3692 Document that this test may be overridden by setting
3693 `ac_cv_exeext'.
3695 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3697 Revert these two patches:
3699 2006-04-06 Eric Blake <ebb9@byu.net>
3700 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3701 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3702 2006-04-01.
3704 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3705 Clean up _AC_COMPILER_EXEEXT* macros.
3706 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3707 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3708 ac_file to the name of the default output file and call
3709 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3710 initial `rm' of the candidate files...
3711 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3712 the same list in subsequent `rm' calls, and for the temporary
3713 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3714 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3715 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3716 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3717 no longer needed) by libtool. Make it a cache check.
3718 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3719 copied here by mistake.
3720 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3721 _AC_COMPILER_EXEEXT.
3722 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
3723 _AC_COMPILER_OBJEXT directly.
3724 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3726 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3728 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
3729 Fix description of how the buggy `sed' works.
3731 2006-05-25 Noah Misch <noah@cs.caltech.edu>
3733 Sync from Automake:
3735 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
3736 ENOLCK. Only mention `make -j' when applicable. Only raise
3737 fatal errors when `make -j' is involved. Improve error message.
3739 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3741 * doc/autoconf.texi (Here-Documents): We now know more about
3742 the variable expansion in here documents bug.
3743 Thanks to Tim Rice and Stepan Kasal.
3745 * doc/autoconf.texi (Making testsuite Scripts): Add an example
3746 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
3748 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3750 * tests/autotest.at (Multiline command from M4 expansion):
3751 No failure to be expected if the shell quotes newlines in
3752 commands in the `set -x' output. Report by Tim Rice.
3753 * THANKS: Update.
3755 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3757 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
3758 expansion in the here-documents used by config.status, as that
3759 runs afoul of the Korn shell version M-12/28/93d bug described in
3760 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
3761 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
3762 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
3764 2006-05-23 Jim Meyering <jim@meyering.net>
3766 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
3767 Fix typo introduced with 2006-04-02 change. It reversed the sense
3768 of the test.
3770 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3772 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
3773 ac_dB slightly, to save bytes in the script.
3774 Max out at 50 lines, rather than 96; this is more likely
3775 (though not guaranteed) to avoid obscure 'sed' failures.
3777 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3779 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
3780 `tr -d -' as bad option argument. Work around this by deleting
3781 an unrelated character.
3782 Report by Tim Rice <tim@multitalents.net>.
3784 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
3785 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3786 Stepan Kasal <kasal@ucw.cz>
3788 * doc/autoconf.texi (Particular Programs): Do not promise that
3789 we always prefer the GNU version of the program, and that we
3790 search according to PATH; both rules can have exceptions.
3791 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
3792 AC_PROG_SED. Move descriptions of limitations
3793 to the Limitations of Usual Tools section.
3794 (Limitations of Usual Tools) <sed>: Mention script length
3795 limitations with Solaris /usr/ucb/sed.
3796 <grep>: Fix wording for empty alternative. Mention that -c and
3797 -l should not be combined, and that -E and -F should not be
3798 combined.
3800 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3801 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3803 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
3804 limits in Solaris 8 /usr/ucb/sed by testing a long script.
3806 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3808 * doc/autoconf.texi (Defining Symbols): Literal parameter of
3809 AC_DEFINE is now passed to m4_pattern_allow.
3810 * NEWS: Mention that; likewise for AC_SUBST.
3811 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
3812 the parameter to m4_pattern_allow.
3813 * tests/tools.at: Add a check for that.
3815 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3817 * lib/autoconf/status.m4: Fix typos.
3819 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3821 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
3822 only the files that this macro generates.
3824 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3826 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
3827 the HP-UX sed limitation of 99 commands, labels do not count.
3828 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
3829 in the comment.
3830 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
3832 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3834 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3835 Import the following fix from coreutils:
3837 2006-01-13 Jim Meyering <jim@meyering.net>
3839 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
3840 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
3841 not double-quote uses of that variable, to accommodate the rare
3842 case in which getmntent is available in none of the libraries
3843 checked. This happens at least on FreeBSD 5.0.
3845 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
3847 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
3848 ac_config_guess, ac_config_sub, and ac_configure, since evidently
3849 some other programs unwisely rely on these undocumented vars.
3850 But put in warning comments about them.
3851 Problem reported by Ralf Wildenhues in
3852 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
3853 * NEWS: Document that these variables are intended to go away.
3855 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3857 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
3858 and set the language to C++ (analogous to the equivalent Fortran
3859 tests).
3861 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
3862 * doc/autoconf.texi (C++ Compiler): Document it.
3863 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
3864 * NEWS: Update.
3866 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
3868 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
3869 that caused config.status to generate 100-command sed scripts; the
3870 portable limit is 99.
3872 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3874 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
3875 variable `ac_d' instead of `d' to avoid infringing namespace.
3876 Report by Ralf Menzel.
3878 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
3880 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
3881 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
3882 * tests/tools.at (autoconf: subdirectories): New test, taken from
3883 the corresponding problem report by Ralf Wildenhues in:
3884 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
3886 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
3887 Quote some uses of shell variables if they might suffer unexpected
3888 globbing. This doesn't fix all instances of quoting problems that
3889 I found, just the easy ones that look safe.
3890 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
3891 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
3892 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
3893 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
3894 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
3895 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
3896 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
3897 Likewise.
3898 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
3899 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
3901 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3903 * bin/autoreconf.in ($help): Reword according to the manual.
3904 Suggested by Olly Betts.
3906 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
3907 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3909 * bin/autoreconf.in: Pass the directory argument to
3910 `require_configure_ac'. Fix comment.
3911 * tests/torture.at (Configuring subdirectories): Expose this.
3912 Reported by Olly Betts.
3914 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3916 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
3917 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
3918 Automake as follows:
3920 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
3921 `$configure_in' instead of `configure.in', to preserve
3922 directory component.
3924 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3926 * config/config.guess, config/config.sub, config/texinfo.tex,
3927 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
3929 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
3931 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
3932 test for C99 conformance; (bool) 0.5 is an integer constant
3933 expression, but (bool) -0.5 is not. Problem reported by Fedor
3934 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
3936 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
3938 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
3939 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
3940 Warn about obsolete install-sh files. Remove stray sentence
3941 fragment and fix cross reference.
3942 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
3943 install -d; this undoes the 2006-05-10 change.
3944 (MKDIR_P): Mark with AN_MAKEVAR.
3945 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
3946 that we don't require $INSTALL to be thread-safe. Move comments
3947 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
3948 of AC_PROG_INSTALL. Output a message saying that we're checking
3949 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
3950 MKDIR_P instead of AC_SUBST.
3951 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
3952 Special magic for MKDIR_P, too.
3953 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
3954 a dnl.
3955 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
3957 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
3959 Sync from Automake, as follows:
3961 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3962 * config/install-sh: Initialize IFS, so field splitting isn't
3963 turned off later.
3964 * config/mkinstalldirs: Likewise.
3965 * config/missing: Remove superfluous quotes. Replace all uses of
3966 `[' by `test', for consistency, and for..
3967 * config/missing (sed_minuso, sed_output): New variables.
3968 (autom4te, help2man, makeinfo): Use them. Unifies detection of
3969 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
3970 Fixes `missing' to detect `--output' for help2man. Fixes
3971 PR automake/483. Report by Dennis J. Linse.
3972 (autom4te): Document in `missing --help'.
3974 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3976 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
3977 * config/install-sh: Don't use 'path' to talk about file names,
3978 as per GNU coding standards. Close a race condition reported by Ralf
3979 Wildenhues and Stepan Kasal. There is still a race condition
3980 on hosts that predate Posix 1003.1-1992, but we can't help this.
3981 Don't mishandle weird characters like space on pre-Posix hosts.
3982 Invoke mkdir at most once per dir arg on pre-Posix hosts.
3983 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
3984 AC_PROG_MKDIR_P from AS_MKDIR_P.
3985 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
3986 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
3987 earlier editions are not (including Automake 1.8.3).
3988 Do not suggest mkinstalldirs for thread-safety.
3989 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
3990 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
3991 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
3992 presence of special characters and race conditions.
3993 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
3994 in Autoconf's name space.
3996 2006-05-10 Bruno Haible <bruno@clisp.org>
3997 and Paul Eggert <eggert@cs.ucla.edu>
3999 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
4000 from Automake with minor changes.
4001 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
4003 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4005 * config/install-sh: Update to Automake CVS version, as follows:
4006 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4007 * lib/install-sh: Simplify the expr implementation of dirname.
4008 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
4009 * lib/install-sh: Handle --, and diagnose unknown options.
4011 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4013 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
4014 `./autom4te' to create `./testsuite', since the `all' target
4015 will ensure its presence, but `installcheck' should not create
4016 the uninstalled wrappers.
4018 * tests/torture.at (Unusual Automake input files): Skip if we
4019 detect automake < 1.8.
4021 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4023 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
4024 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
4025 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
4026 * NEWS: Update.
4028 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4030 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
4031 munge (multiple) white space and other oddities.
4032 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
4033 single quotes in variable assignment.
4034 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
4035 and similar failures by adding multiple spaces, tabs, and other
4036 special characters.
4037 Report and different test suggested by Francesco Romani
4038 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
4040 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
4041 single quotes, we only need to search for single quotes; this
4042 both simplifies the search pattern, and makes us less
4043 susceptible to `echo' variations for arguments not containing
4044 single quotes.
4045 (_AC_ARG_VAR_VALIDATE): Likewise.
4047 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4049 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
4050 `$*' and IFS concatenation issue with traditional shells and
4051 bash-2.04. Report by Seanster@Seanster.com.
4053 2006-05-03 Bruno Haible <bruno@clisp.org>
4055 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
4056 precisely which Mac OS X versions have the od problem.
4058 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4060 * doc/autoconf.texi: Use @option systematically.
4062 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4063 and Bruno Haible <bruno@clisp.org>
4065 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
4066 about 'od'.
4067 (Integer Overflow): Mention the special case of integer division
4068 overflow.
4070 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4072 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
4073 traditional shells like the Solaris one that do not use the
4074 first IFS character for assembling `$*'.
4075 Prompted by a related report from autoconf_bug@nro.ca.
4077 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
4078 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4080 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
4081 Mention more problems with the -e option.
4083 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4085 * NEWS: Typo.
4086 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
4088 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
4089 in URLs to improve DVI formatted output (requires texinfo 4.6).
4090 (System Services, Systemology, Shellology): Likewise.
4091 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
4092 output.
4094 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
4095 continuous text.
4096 (Runtime): Fix macro argument names to match description:
4097 `action-if-found' -> `action-if-true' and similarly.
4098 (Obsolete Macros): Likewise.
4099 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
4100 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
4101 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
4103 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4105 * doc/autoconf.texi (Limitations of Make): Clean up markup.
4107 * ChangeLog: Typo.
4108 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
4109 DVI output.
4111 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4118 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
4120 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
4121 (Integer Overflow, Null Pointers, Buffer Overruns):
4122 (Floating Point Portability, Exiting Portably): New sections.
4123 (Writing Test Programs): Fix some langauge. Recommend exiting
4124 with status 1, not merely nonzero. Clarify exit declaration.
4125 (Run Time): Move C exit status stuff to new Exiting Portably section.
4126 (Systemology): Mention Posix and levenez. Update v7 reference.
4127 (Portable Shell): Mention the Posix shell.
4129 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4131 * bin/autoconf.as (me): Replace by as_me.
4133 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
4135 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
4136 since as_me isn't set yet.
4138 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4140 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
4141 a few minor bugs in this area.
4143 * doc/autoconf.texi (Programming in M4sh): Comment out the
4144 documentation of AS_BASENAME, for now.
4145 (Shell Substitutions): Do not use AS_DIRNAME in an example.
4146 (Limitations of Builtins) <basename>: Do not refer to
4147 AS_BASENAME.
4148 * bin/autoconf.as (me): Don't use AS_BASENAME.
4149 (dir): Remove the unused variable.
4150 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
4151 AS_DETECT_REQUIRED. All uses changed.
4152 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
4153 All uses changed.
4154 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
4155 (AS_BASENAME): Use "basename --" to protect against leading "-".
4156 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
4157 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
4158 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
4159 (_AS_DIRNAME_PREPARE): Likewise.
4160 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
4161 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
4162 (AS_DIRNAME): Use "dirname --".
4164 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4166 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
4167 of "run time" and "run-time" changed to "runtime", for consistency.
4168 * lib/autoconf/fortran.m4: Likewise (in comment).
4169 * lib/autoconf/functions.m4: Likewise.
4170 * lib/autoconf/general.m4: Likewise.
4171 * lib/autoconf/headers.m4: Likewise.
4173 * doc/autoconf.texi (Run Time): Document the exit status situation
4174 with more accuracy and detail.
4176 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4178 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
4179 Archive is not officially `GNU' any more. Update URL.
4180 (Defining Directories): Likewise
4181 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
4183 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4185 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
4186 newline from the `trap' code to finish `config.log'; the NetBSD
4187 /bin/sh resets the exit status after an empty command, as
4188 documented in doc/autoconf.texi.
4189 Reported by Dalibor Topic <robilad@kaffe.org>.
4191 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
4193 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
4194 Suggested by Bruno Haible.
4196 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
4198 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
4199 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
4200 Instead, just list the shells that we know work.
4201 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
4202 changed. Be more cautious about the _cv_ variable.
4203 * tests/tools.at (Syntax of the shell scripts): Check the
4204 _cv_ variable once, at first, to avoid an internal autoconf error
4205 when sh -n does not work.
4207 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4209 * lib/Autom4te/FileUtils.pm: Sync from Automake.
4211 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
4213 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
4214 use ">&-" since we're only 99.999% sure that this is portable,
4215 and since the MinGW bug is fixed in a different way.
4216 * lib/autotest/general.m4 (AT_INIT): Likewise.
4218 2006-04-16 Stepan Kasal <kasal@ucw.cz>
4220 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
4221 before opening config.log, to avoid hitting a bug on MinGW.
4223 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
4225 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
4226 AS_MESSAGE_LOG_FD before reopening it onto the log file.
4227 This works around a MinGW bug reported by Eric Paire.
4228 Make sure that all writes to the log file append to it,
4229 rather than possibly losing data.
4230 * lib/autotest/general.m4 (AT_INIT): Likewise.
4232 2006-04-14 Stepan Kasal <kasal@ucw.cz>
4234 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
4235 description.
4237 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4239 * NEWS: Update.
4241 * configure.ac (AC_INIT): Bump to 2.59d.
4243 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4245 Version 2.59c.
4247 * Makefile.maint (news-date-check): Do not require a leading `*'
4248 before the release date in NEWS.
4250 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4251 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4253 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
4254 the instantiated file do not contain the string 'datarootdir'
4255 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
4256 @mandir@, replace the reference '${datarootdir}' by the value.
4257 * tests/torture.at (datarootdir workaround): New test.
4258 * NEWS: Advertise this temporary fixup.
4259 Based on a patch by Bruno Haible, reported and analyzed by
4260 Paul Eggert and Noah Misch.
4262 2006-04-12 Eric Blake <ebb9@byu.net>
4264 * tests/autotest.at (Debugging a failed test): Fix comment.
4266 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4268 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
4269 all the changes since 2006-04-07.
4271 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4273 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
4274 succeeded, but `ln -s file dir' failed, take care to remove the
4275 leftover target before the next test, to prevent its spurious
4276 failure; also make sure `ln file dir' works before selecting it.
4277 Thanks to Keith Marshall for pointing this out.
4278 * THANKS: Update.
4280 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
4281 assignments in `at_debug_args', so that we put them correctly
4282 in the `run' script.
4283 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
4284 Reported by Eric Blake.
4286 2006-04-11 Eric Blake <ebb9@byu.net>
4288 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
4289 top-level tests after micro-suite has been run. Used in...
4290 (Debugging a successful test, Debugging script and environment),
4291 (Debugging a failed test): ...these new tests. The first of these
4292 is fixed by...
4293 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
4294 macro, split out from...
4295 (AT_INIT): ...here, so that using -d also generates a run script.
4296 Document that -d inhibits top-level logging.
4297 * doc/autoconf.texi (testsuite Invocation): Document that -d only
4298 inhibits top-level logging; debug scripts are created.
4300 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
4301 check.
4302 * tests/autotest.at (Empty test, Empty check): New test to check it.
4304 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
4305 from gcc.
4307 2006-04-10 Stepan Kasal <kasal@ucw.cz>
4309 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
4310 the files if a problem appears. Make the empty *.at files
4311 read-only, too. Proposed by Ralf Wildenhues.
4313 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4315 * config/Makefile.am: Add comment to force updated Makefile.in.
4317 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
4318 space only patch to this file, this patch causes the Makefile.in
4319 files that include freeze.mk to be updated, and thus have a
4320 newer time stamp again, which in turn makes a pristine CVS
4321 checkout have correct time stamps.
4323 * Makefile.maint (cvs-sv): New macro, to be used..
4324 (config.guess-url_prefix, config.sub-url_prefix)
4325 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
4326 point to CVS text checkout of Gnulib files.
4327 (copyright-check): Bump current year.
4328 (announcement): Do not hard-wire `./announce-gen'.
4329 (cvs-update): Propagate failures of `cvs' and `move-if-change'
4330 correctly.
4331 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
4332 `chmod +x'.
4333 (wget_files): Update config.guess, config.sub, texinfo.tex by
4334 `wget-update', now that their URLs work again.
4336 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4338 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
4339 Problem noted by Paul D. Smith.
4341 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4343 * doc/autoconf.texi: Remove unused words from word list.
4344 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
4345 .x-sc_trailing_space: New files.
4347 * doc/standards.texi: Sync from gnulib.
4349 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
4350 `LIBOBJDIR' as experimental.
4352 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
4353 with a target directory; it's internally implemented as `cp'
4354 anyway, but since Autoconf advertises the possibility to use
4355 a target directory when LN_S is `ln -s', we need to find out.
4356 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
4357 analyzed by Keith Marshall <keith.marshall@total.com>.
4359 * THANKS: Update.
4361 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4363 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
4364 confdefs.h as-is. In general, if it has backslash-newline or the
4365 like, then it doesn't work either to sort or to remove empty
4366 lines.
4368 2006-04-09 Stepan Kasal <kasal@ucw.cz>
4370 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
4372 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
4374 * lib/autom4te.in (Automake-preselections): Preselect
4375 _AM_SUBST_NOTMAKE.
4377 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4379 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
4380 apostrophe within a single-quoted string, as this is the usual
4381 tradition and is easier to read than '"'"'. Don't rely on the
4382 shell treating "$/" like '$/'. Use a more-consistent indenting
4383 style for the trap.
4385 2006-04-09 Eric Blake <ebb9@byu.net>
4387 * tests/autotest.at (Backquote command substitution),
4388 (Multiline backquote command substitution): Remove mistaken
4389 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
4390 applied...
4391 (Parenthetical command substitution, Multiline parenthetical
4392 command substitution): here.
4394 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4396 Import macros from gnulib (often changing their name).
4398 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
4399 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
4400 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
4401 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,

4403 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
4404 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
4405 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
4406 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
4407 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
4408 The manual mentions Gnulib more prominently.
4409 * doc/autoconf.texi (Gnulib): New node.
4410 (Pointers): Add Gnulib URL.
4411 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
4412 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
4413 Gnulib section.
4414 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
4415 suggest a #define rather than a typedef for _Bool, and mention
4416 Gnulib rather than trying to substitute stdbool code.
4417 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
4418 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
4419 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
4420 AC_STRUCT_DIRENT_D_TYPE.
4421 (Particular Types): Mention stdint.h and inttypes.h as standard
4422 headers too.
4423 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
4424 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
4425 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
4426 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
4427 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
4428 (C Compiler): Move AC_C_LONG_DOUBLE to ...
4429 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
4430 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
4431 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
4432 (Coding Style). Don't mention m4_expand_once.
4433 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
4434 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
4435 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
4436 (AC_CHECK_FUNCS): Use it.
4437 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
4438 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
4439 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
4440 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
4441 (AC_HEADER_ASSERT): New macro.
4442 (AC_HEADER_STDBOOL): Don't assume "#error" works.
4443 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
4444 Catch a bug in an HP-UX C compiler.
4445 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
4446 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
4447 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
4448 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
4449 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
4450 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
4451 New macros.
4453 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
4454 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
4456 2006-04-08 Stepan Kasal <kasal@ucw.cz>
4458 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
4459 of the warning introduced by the 2001-08-28 change.
4461 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
4462 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4464 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
4465 variables shall be overriden by the cache.
4466 * tests/torture.at (AC_ARG_VAR): Test also with a first value
4467 that contains braces.
4469 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4471 Revert the patch from 2006-04-01 and only improve
4472 _AS_DETECT_BETTER_SHELL:
4474 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
4475 skip nonexistent directories.
4476 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
4477 only shell candidates which exist.
4478 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
4479 * lib/autotest/general.m4 (AT_INIT): No need to give three
4480 parameters to _AS_PATH_WALK.
4482 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
4483 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4485 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
4486 distinguish m4sugar macros.
4487 * tests/tools.at (autoupdating with aclocal and m4_include):
4488 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
4489 test case by Noah Misch <noah@cs.caltech.edu>.
4491 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4493 Revert my change from 2006-03-17, in other words:
4494 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
4495 and DUALCASE=1.
4496 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
4497 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
4498 it is set.
4500 2006-04-07 Eric Blake <ebb9@byu.net>
4502 * doc/autoconf.texi (Programming in M4sh): Document that
4503 AS_MKDIR_P exits the script on failure.
4504 * lib/autotest/general.m4: Remove redundant AS_ERROR.
4506 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4508 * config/elisp-comp, config/install-sh, config/mdate-sh,
4509 config/missing, config/mkinstalldirs: Sync from Automake.
4511 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
4512 from Automake.
4514 * doc/make-stds.texi: Sync from gnulib.
4516 2006-04-06 Eric Blake <ebb9@byu.net>
4518 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4519 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4520 2006-04-01.
4522 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
4523 Eric Blake <ebb9@byu.net>,
4524 Paul Eggert <eggert@cs.ucla.edu>,
4525 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4527 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
4528 whether `set' quotes correctly: redirect stderr of the tested
4529 `set', and use a subshell, for Ultrix; use `sed' instead of
4530 `grep' for zsh `set' which may write binary output; match only
4531 at the beginning of a line, to avoid false positives.
4532 In order to avoid false positives by unrelated variables with
4533 multiline content, put the dump algorithm in a subshell and
4534 unset all variables containing newlines (except some which are
4535 special to the shell). Warn about cache variables that are
4536 unset.
4538 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4540 * config/config.guess, config/config.sub, config/texinfo.tex:
4541 Sync from upstream.
4543 * tests/mktests.sh: Reword comments.
4545 * tests/mktests.sh: Only skip internal macros starting with
4546 `_AC_' or `__AC_'. Noted by Stepan Kasal.
4547 Update exclusion lists for the test suite to this end:
4548 (AC_ARG_VAR): Do test this now.
4549 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
4550 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
4551 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
4552 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
4554 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
4555 shell issue with double-quoted command substitutions of native
4556 commands.
4557 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
4558 Marshall.
4560 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
4561 no file matches the glob, discard the warning, set `nullglob'.
4562 (syntax-check): Likewise.
4563 (sc_cast_of_x_alloc_return_value): Likewise.
4564 (sc_cast_of_alloca_return_value, sc_error_exit_success)
4565 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
4566 (m4-check): Likewise.
4567 (sc_system_h_headers): Do not print rule on execution.
4568 (sc_tight_scope): Do not fail for non-existing `src' directory.
4569 (sc_changelog): Skip the Copyright footer.
4570 * lib/autoconf/lang.m4: Remove trailing space.
4572 * lib/autoconf/status.m4: More replacements to
4573 <tab><space> where this makes sense.
4575 2006-04-06 Stepan Kasal <kasal@ucw.cz>
4577 * tests/Makefile.am (maintainer-check-posix):
4578 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
4580 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
4581 ac_config_<foo>s again, sometimes normalized, sometimes not.
4582 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
4583 (AC_CONFIG_COMMANDS): Do not do so here.
4584 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
4585 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the

4596 for --help from Cygnus `configure.'
4598 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
4600 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up

4619 lib/autoconf/specific.m4, lib/autoconf/status.m4,
4620 lib/autoconf/types.m4, lib/autotest/general.m4,
4621 tests/mktests.sh, tests/torture.at: White space cleanup:

4651 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
4652 Use 'comm' rather than N instances of grep; this also fixes a bug
4653 whereby substrings were incorrectly matched, causing us to not
4654 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
4655 (exclude_list): Exclude empty macros.
4656 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

4661 Switch from grep to awk syntax.
4662 (ac_exclude_script): Renamed from ac_exclude_egrep.

4739 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4740 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4741 ac_file to the name of the default output file and call
4742 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4743 initial `rm' of the candidate files...
4744 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4745 the same list in subsequent `rm' calls, and for the temporary
4746 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4747 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4748 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4749 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4750 no longer needed) by libtool. Make it a cache check.
4751 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4752 copied here by mistake.
4753 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4754 _AC_COMPILER_EXEEXT.
4755 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

4791 subordinate tools.
4792 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
4793 * doc/autoconf.texi (autoreconf Invocation): Document it.
4795 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

4807 the correct lines of the input file by subtracting..
4808 (_au__first_line): ..this new definition.

4811 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
4812 Remove stray newline in output.

4827 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4829 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
4830 switch all of them on and of when necessary. Fixes the bug when
4831 m4sugar macros (e.g., m4_define) were expanded after the first
4832 automatic update (e.g., after AC_PREREQ or AC_INIT).
4834 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

4865 (File System Conventions): Put discussion of // versus / here, and
4866 modernize it a bit.

4882 checked for existence, so we don't barf over a nonexisting
4883 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
4885 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4950 (AC_CHECK_SIZEOF, AC_CHECK_SIZEOF struct): Use it.

5009 keywords, keywords taken from AT_SETUP arguments, and numeric

5029 trying to execute the command `no'.
5031 * lib/autoconf/lang.m4 (AC_LANG_CONFTEST): AC_DEFUN this, not

5501 conftest.o, to see whether the compiler really obeys; rm the object
5502 file before and after the test and register it with ac_clean_files.
5503 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
5505 2005-10-21 Stepan Kasal <kasal@ucw.cz>
5507 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
5508 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
5509 code so that the most common case requires less forks.
5511 2005-10-20 Stepan Kasal <kasal@ucw.cz>
5513 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
5514 not portable; thanks to Paul Eggert and Alexandre.
5516 * NEWS: Fix an old typo.
5518 2005-10-20 Jim Meyering <jim@meyering.net>
5520 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
5521 the latter'', in two places.
5523 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
5525 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
5526 AC_LANG_PROGRAM, fixing a typo. Don't give details about
5527 the inner workings of AC_LANG_FUNC_LINK_TRY.
5528 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
5529 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
5530 by the function rather than ignoring it.
5531 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
5532 comparing its address. Intel's interprocedural optimization was
5533 outsmarting the old heuristic. Problem reported by
5534 Mikulas Patocka.
5536 2005-10-19 Stepan Kasal <kasal@ucw.cz>
5538 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
5540 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
5542 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
5543 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
5545 2005-10-04 Stepan Kasal <kasal@ucw.cz>
5547 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
5548 before removing it (chmod -R u+rwx); there are three instances of this.
5550 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5551 Stepan Kasal <kasal@ucw.cz>
5553 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
5554 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
5555 make its content writable before removing it. Remove an errorneous
5556 comment from the end, where the logs of the failed tests are copied
5557 to the main log file.
5559 2005-09-27 Stepan Kasal <kasal@ucw.cz>
5561 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
5562 in case the computer is too quick. Double quote the configure.ac
5563 snippets.
5565 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
5566 problems if the testsuite were running too fast.
5568 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5570 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5571 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5572 (which belong to Xt, not X itself). See Debian bug 327655.
5573 * NEWS: Mention this.
5575 2005-09-07 Stepan Kasal <kasal@ucw.cz>
5577 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
5579 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
5581 * config/move-if-change: Don't output "$2 is unchanged";
5582 suggested by Ben Elliston. Handle weird characters correctly.
5584 2005-09-06 Stepan Kasal <kasal@ucw.cz>
5586 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
5587 calls, so that the final expansion of this macro is shorter.
5588 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
5589 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
5590 the cleanup there. Use AS_VAR_* macros, to be more general.
5591 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
5593 * lib/autoconf/general.m4: Use AS_IF where appropriate.
5595 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
5597 2005-09-01 Stepan Kasal <kasal@ucw.cz>
5599 * doc/autoconf.texi (Configuration Headers): Add an index entry
5600 for AH_HEADER.
5602 2005-08-26 Pavel Roskin <proski@gnu.org>
5604 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
5605 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
5606 running xmkmf.
5608 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
5610 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
5611 The previous patch didn't work, so try a better one.
5613 2005-08-26 Stepan Kasal <kasal@ucw.cz>
5615 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
5616 in the example. Reported by Bruno Haible.
5617 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
5618 "if $undefined_var;" succeeds with my shell.
5620 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
5621 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
5622 but change the m4_divert_text to m4_divert_once.
5624 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
5626 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
5627 Work around bug in Solaris /usr/xpg4/bin/awk.
5628 The bug is present in at least Solaris 8 through 10.
5630 2005-08-24 Stepan Kasal <kasal@ucw.cz>
5632 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
5633 some evil values and relying on the fact that $* concatenates the
5634 parameters by the first character from IFS.
5636 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5637 Stepan Kasal <kasal@ucw.cz>
5639 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
5640 first header appears, define AH_HEADER.
5641 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
5642 Update limitations about when to call AC_CONFIG_HEADERS.
5643 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
5644 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
5645 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
5646 ``Configuration Actions''; fix their index entries.
5648 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
5649 options correctly. Process N-M as M-N if M is smaller than N.
5650 Process ranges correctly so that N-N will run only N.
5651 Sort and uniquify the tests that will be run. If there is more
5652 than one test, reinsert the banners for the tests.
5653 * tests/autotest.at (Keywords): Unmark XFAIL.
5655 2005-08-23 Stepan Kasal <kasal@ucw.cz>
5657 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
5658 before passing the macro name to AH_TEMPLATE.
5660 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
5661 now opens log after option processing; in particular, --version
5662 and --help do not touch config.log.
5664 * Makefile.maint: Revert the change from 2005-08-12.
5666 2005-08-22 Stepan Kasal <kasal@ucw.cz>
5668 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
5669 common code to...
5670 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
5672 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5674 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
5675 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
5676 Language cleanup.
5678 * doc/autoconf.texi (Defining Symbols, Changed Results):
5679 Prepend to LIBS, not append, in examples.
5681 2005-08-16 Stepan Kasal <kasal@ucw.cz>
5683 When building in place, set srcdir="."; suggested by Tim Van Holder.
5685 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
5686 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
5687 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
5688 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
5689 does not mean "no --srcdir option".
5691 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5693 * tests/autoscan.at (autoscan): New file.
5694 * tests/suite.at: Use it.
5695 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
5696 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
5698 * tests/autotest.at (Keywords): Test keywords combinations.
5700 2005-08-12 Stepan Kasal <kasal@ucw.cz>
5702 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
5703 add "2>&1"; gzip 1.2.4 prints help on stderr.
5705 2005-07-27 Stepan Kasal <kasal@ucw.cz>
5707 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
5708 was pushdef'ed twice while popped only once. Push it only once.
5709 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
5711 2005-07-26 Stepan Kasal <kasal@ucw.cz>
5713 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
5714 prefixed by mere "===", not "configure: === ".
5716 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
5718 * Makefile.maint: Update from Bison.
5720 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
5721 "<tab>" in comment, so that the point is understandable.
5723 2005-07-25 Stepan Kasal <kasal@ucw.cz>
5725 Rewrite substantial part of lib/autoconf/status.m4.
5726 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
5727 and CONFIG_COMMANDS are not processed in four separate loops.
5728 Instead, there is one main loop. This alows that the common code
5729 is expanded only once, thus config.status (and configure) is smaller.
5731 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
5732 the AC_LIST_FILES and cousins macros are no longer used.
5734 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
5735 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
5736 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
5737 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
5738 contain the initialization, nor the for loop, nor the associated
5739 commands; all these go to ...
5740 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
5741 _AC_OUTPUT_CONFIG_STATUS.
5742 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
5743 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
5744 (_AC_OUTPUT_FILE): The creation of the sed script ...
5745 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
5746 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
5747 _AC_OUTPUT_MAIN_LOOP.
5748 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
5749 _AC_CONFIG_COMMANDS): Use ...
5750 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
5751 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
5752 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
5753 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
5754 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
5755 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
5756 ... new macros.
5757 (_AC_CONFIG_UNIQUE): Update.
5758 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
5759 Replaced by this ...
5760 (_AC_LIST_TAGS): ... new common macro.
5761 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
5762 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
5763 (_AC_LIST_TAG_COMMANDS): ... new common macro.
5764 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
5765 this didn't belong to the `config commands' section.
5766 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
5767 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
5768 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
5769 to the `config commands' section either.
5770 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
5771 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
5773 ... and many changes to the comments nearby.
5775 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
5776 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
5777 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5778 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
5779 (#define header templates): The comment at the top of the generated
5780 header now includes the name(s) of the source file(s).
5782 Several unrelated small changes:
5784 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
5785 parameter to AC_DIAGNOSE.
5786 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
5787 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
5788 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
5789 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
5790 with AU::AC_OUTPUT.
5791 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
5792 in AC_OUTPUT doesn't double-quote it either.
5793 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
5794 parameters.
5796 2005-07-10 Stepan Kasal <kasal@ucw.cz>
5798 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
5799 versions of Portland Group compiler produce single- and double-quoted
5800 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
5801 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
5803 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
5805 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5806 This is a corrected version of yesterday's patch.
5808 2005-07-07 Stepan Kasal <kasal@ucw.cz>
5810 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
5811 path, too; insert a "===" to emphasize the line.
5813 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
5814 ac_cv_build_alias to ac_build_alias.
5815 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
5817 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
5818 change eliminates it. Problem reported by Alexandre Duret-Lutz.
5819 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
5820 (AC_ARG_VAR): ... here.
5821 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
5822 target_alias.
5824 Keep a list of all precious variables and process them with one simple
5825 for loop, instead of expanding all commands, or, OTOH, complicated
5826 processing of output of "set".
5827 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
5828 variable names in new macro...
5829 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
5830 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
5831 a loop to assign all ac_env_* and ac_cv_env_* variables.
5832 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
5833 to INIT_PREPARE.
5834 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
5835 its value to shell variable ac_precious_vars and call
5836 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
5837 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
5838 _AC_ARG_VAR_VALIDATE.
5840 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
5841 and the AC_SUBSTs ...
5842 (AC_INIT): ... here.
5844 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
5845 the ac_subst_files section in config.log.
5847 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
5849 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

5854 * tests/c.at (C keywords): Test AC_C_TYPEOF.
5856 Fix problems reported by Nicolas Joly.
5857 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
5858 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5859 They are generated by the Tru64 v5.1B shell.
5861 2005-07-05 Stepan Kasal <kasal@ucw.cz>
5863 Fix my changes from 2005-07-01; reported by Noah Misch.
5864 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
5865 description, the macro now accepts only a single tag.
5866 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
5868 Fix cases when the varsions of Autoconf and Autotest don't match.
5869 Reported by Noah Misch.
5870 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
5871 at_top_builddir, for compatibility with older autotest.
5872 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
5873 is not set, use at_top_builddir, for compatibility with older
5874 versions of autoconf.
5876 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
5878 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
5879 Problem reported by Patrick Welche.
5881 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
5883 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
5884 sed substitution command, so that we allow | in program prefixes
5885 and program suffixes. (& is a problem anyway; we're not fixing
5886 that here.)
5887 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
5888 configure_input, top_builddir, srcdir, etc.
5889 * lib/autotest/general.m4 (AT_INIT): Likewise, for
5890 PATH_SEPARATOR in AUTOTEST_PATH.
5892 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
5894 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
5895 for loop over config.site files using `set', to allow
5896 directory names containing IFS characters.
5898 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
5900 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
5901 directories with weird names. Apparently some people like living
5902 on the edge. However, improve the test that "pwd" actually does
5903 report a name for the working directory.
5904 * NEWS: Remove the claim that we test for funny chars in dir names.
5906 2005-07-01 Stepan Kasal <kasal@ucw.cz>
5908 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
5909 replaced ...

5918 about #include <config.h>.
5919 (Generic Functions): Mention the Gnulib project.
5920 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
5922 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
5923 document to output the default config_* lists to config.status.
5924 Don't recognize option --file, if the functionality is not there.
5925 Likewise for --header; moreover, recognize --he and --h as shortcuts
5926 for --help in that case.
5928 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
5929 matches the order of execution. No code changed.
5931 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5933 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
5934 single-quoted -cmdline argument in Portland Group compiler.
5935 Reported against LAM by Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
5937 2005-06-30 Alexandre Duret-Lutz <adl@gnu.org>

5944 descriptors to child processes; reported by Norman Gray.
5946 2005-06-29 Stepan Kasal <kasal@ucw.cz>
5948 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
5950 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
5951 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
5952 (AC_SUBST): Call it.
5953 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
5954 the directory specific variables; but don't call it for configure_input.
5956 2005-06-28 Derek Price <derek@ximbiot.com>
5958 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
5959 addition.
5961 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
5963 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
5964 directory have inherent problems with special characters like spaces,
5965 due to limitations in Make syntax. Problem reported by Alexandre
5966 Duret-Lutz.
5967 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
5968 Also, fix Tru64 porting problem with shell patterns,

5980 from Justace Clutter.
5981 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
5982 variable into diagnostic. Make the diagnostic an error, not a warning,
5983 because we really don't support spaces and suchlike in dir names.
5984 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
5985 Don't worry about backslashes in srcdir; it can't happen now.
5986 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
5987 Simplify ac_optarg handling.

5996 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
5998 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
5999 that '\|' is not allowed in BREs; recommend using newline separated
6000 list of patterns instead of multiple -e options.

6012 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
6013 b, t, r, w commands require single space, while : cannot have any.
6014 (Special Shell Variables): Fix sed code this in the example.
6015 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
6016 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
6018 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
6019 expand to the empty list. Don't use two pairs of m4_changequote,
6020 it's not necessary.
6022 2005-06-20 Derek Price <derek@ximbiot.com>
6024 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
6026 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
6028 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
6029 * doc/autoconf.texi:
6030 Don't mention Solaris versions so much, if a
6031 problem is common to all extant versions of Solaris. Say "SunOS
6032 4" instead of "SunOS" for SunOS 4.
6033 (awk): Mention more of the limitations of traditional Awk.
6034 (cat): Don't talk about cat -v.
6036 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
6038 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
6039 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
6040 but the implementation is entirely different and is designed
6041 to be compatible with glibc strverscmp.
6042 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
6044 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
6045 on Mac OS X 10.4 reported by Peter O'Gorman in:
6046 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
6047 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
6048 Use shell builtins rather than 'expr', to work around expr bug.
6050 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
6052 * doc/autoconf.texi: "filesystem" -> "file system".
6053 "behaviour" -> "behavior".
6054 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
6055 * lib/autoconf/general.m4: Omit blank after ":" sed command,
6056 as per POSIX.
6057 * lib/m4sugar/m4sh.m4: Likewise.
6058 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
6059 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
6061 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
6062 (.x.1): Ignore the time stamp in the .TH line when deciding whether
6063 to update the man page. That way, we don't have to check in new
6064 man pages every month.
6066 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
6067 quotes and backslashes. Patch from Derek Price.

6072 AS_TR_SH.
6074 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
6076 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
6077 -u, since it outputs chatter if the input files are the same.
6078 Problem reported by Ralf Menzel.
6080 2005-06-08 Derek Price <derek@ximbiot.com>
6082 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
6083 renaming them since they are about to be redefined anyhow.
6085 2005-06-08 Derek Price <derek@ximbiot.com>
6087 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
6088 redefined M4 macros to this node. Document m4_include & m4_sinclude.
6089 Move m4_undefine to alphabetical order.
6091 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
6093 * README: Recommend GNU M4 1.4.3 or later.
6094 * doc/autoconf.texi (Introduction): Likewise.
6095 Reword to avoid some formatting glitches.
6096 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
6097 Clarify explanation of HP compiler bug.
6098 Redo example output tp match current CVS snapshot.
6099 Use @example.org in email addresses when the examples
6100 might get inadvertently cut-and-pasted into user code.
6101 Remove example of autom4te usage that doesn't seem to work now.
6102 Use modern AC_INIT (except when the example is meant to be
6103 shown with Autoconf 2.13).
6104 Update ksh info for Solaris 9 and later.
6105 KB -> kB.
6106 Modernize description of Automake versions a bit.
6107 Don't claim a future version of Autoconf is near.

6110 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6112 * doc/autoconf.texi: Add [] to examples, so that the manual
6113 follows its own advice about quoting better.
6114 Reword to avoid some formatting glitches.
6115 * doc/installt.exi: Reword to avoid some formatting glitches.
6117 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
6118 Tru64 ksh pattern matching bug. Reported against Libtool by
6119 Albert Chin <libtool@mlists.thewrittenword.com> and
6120 Nicolas Joly <njoly@pasteur.fr>.
6122 2005-06-06 Stepan Kasal <kasal@ucw.cz>
6124 m4_cdr of one-member list was [[]] (one-member list containing an
6125 empty string) instead of [] (an empty list. Callers were skewed to
6126 match this misbehaviour. As a consequence of this:
6127 - m4_foreach([x], [], [foo]) expanded to `foo', while
6128 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
6129 This bug has been fixed:
6131 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
6132 expand to an empty string; print error msg if called without
6133 an argument list.
6134 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
6135 misbehaviour; handle [] and [[]] correctly.
6137 2005-06-06 Stepan Kasal <kasal@ucw.cz>
6139 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

6141 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
6143 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
6145 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
6146 swallow records with more than 99 fields.
6147 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
6148 parse the long line.
6150 2005-06-04 Stepan Kasal <kasal@ucw.cz>
6152 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
6153 swallow literals longer than 399. Reported by Ralf Wildenhues.
6154 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
6155 to workaround this limitation.
6157 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
6159 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
6160 to gfortran, and make these the first two compiler names
6161 checked (following the general autoconf preference for gcc).
6163 2005-06-03 Stepan Kasal <kasal@ucw.cz>
6165 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
6166 (DISTCLEANFILES): Remove $(check_SCRIPTS).
6167 (testsuite): Make sure autotest.m4f is up-to-date before using it.
6169 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
6171 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
6172 expression of unbounded size when processing the --list
6173 option. This runs afoul of a limit of 399 bytes per regular
6174 expression on AIX. Problem reported by Ralf Wildenhues.
6176 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
6178 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
6179 * doc/autoconf.texi (Particular Headers): Reword example
6180 for multiline stdbool replacement.
6181 (Setting Output Variables): Reword text a bit. Don't
6182 give all the details about |#_!!_#|.
6183 Reword description of line replacement.
6185 2005-05-31 Dan Manthey <dan_manthey@partech.com>
6187 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
6188 now contain newlines, and substituted files must be referenced on
6189 a line alone; the sed scripts to substitute them are now very
6190 different.
6191 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
6192 commands can be put in a sed script portably.
6193 * doc/autoconf.texi (Setting Output Variables): Document above
6194 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
6195 use of multiline substitution.

6205 * tests/local.at: Don't attempt to check for negated character
6206 classes in shell scripts. The test was too brittle.
6208 2005-05-25 Stepan Kasal <kasal@ucw.cz>
6210 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
6211 * doc/autoconf.texi (Limitations of Builtins): Document this
6212 limitation.
6214 2005-05-24 Stepan Kasal <kasal@ucw.cz>
6216 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
6217 common code; used in many places in the tree.

6224 messages when ac_unique_file is not found.
6225 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
6226 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
6227 commands, for consistency with AC_MSG_ERROR and such.
6229 * bin/autoconf.as: Make more use of "shift 2" in option processing.

6239 2005-05-20 Stepan Kasal <kasal@ucw.cz>
6241 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
6242 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
6243 (ac_top_builddir): ... this ...
6244 (ac_top_build_prefix): ... to this; the old name is also kept, for
6245 backward compatibility.
6246 (ac_top_builddir_sub): New variable, without the trailing slash,
6247 always nonempty.
6248 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
6249 * doc/autoconf.texi (Configuration Actions): Rename
6250 ac_top_builddir to ac_top_build_prefix.
6251 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

6262 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
6263 argument to m4_foreach. I guess it was necessary in the past,
6264 but I think it's a no-op now.
6266 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6268 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
6269 ``cat <<_ACEOF'' commands to one.
6270 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
6271 * lib/autoconf/status.m4: On various places, use expr instead of
6272 ``echo|sed.''
6273 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
6274 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
6275 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
6276 a range.
6277 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for

6279 code had false positives.
6281 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
6283 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
6284 as on 2005-05-02.
6285 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

6348 quoting rules. Problems noted by Stepan Kasal.
6349 Also, throughout this document, be more careful about white space.
6350 "blank", "white space", and "space" all have different meanings
6351 and we should be careful to say what we mean.

6401 processed correctly in AS_HELP_STRING; avoid this in the examples.
6402 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
6403 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
6404 comment and reduce m4_default([foo], []) to [foo].
6405 (m4_strip): Update the explanation.
6407 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
6409 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
6410 Remove core.conftest.* too; it's generated by Tru64 5.1.
6411 Problem reported by Jennis Pruett.
6412 * lib/autoconf/functions.m4
6413 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
6414 Don't bother to remove core files; AC_RUN_IFELSE should do that
6415 for you.
6417 2005-04-19 Stepan Kasal <kasal@ucw.cz>
6419 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

6426 2005-04-15 Stepan Kasal <kasal@ucw.cz>
6428 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
6429 the comment.
6431 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
6433 * doc/autoconf.texi (External Software, Package Options): Add
6434 examples showing how to implement --with-* and --enable-* options.
6436 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
6438 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
6439 as well as configure.in. Problem reported by Gregorio Guidi.
6441 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
6443 * doc/autoconf.texi (Particular Functions): Use gnulib's current
6444 pattern for alloca snippet.

6454 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
6456 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
6457 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
6459 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6461 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
6462 Merge `-z option' as well for the benefit of Solaris link flags. Pass
6463 whole-archive (-zallextract, -zdefaultextract) options in the hope of
6464 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
6465 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
6467 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
6469 * NEWS: The configure command now warns you if you attempt to use
6470 a directory whose name contains a special character like space,
6471 newline, or "\".
6472 * doc/autoconf.texi (Installation Directory Variables): Allow
6473 "," in file names. Do not use \@; it's not a portable regexp.
6474 * bin/Makefile.am (edit): Likewise.
6475 * lib/Makefile.am (edit): Likewise.
6476 * tests/Makefile.am (edit): Likewise.
6477 * tests/semantics.at: Likewise.

6480 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
6481 * doc/autoconf.texi (File System Conventions): Warn about
6482 unportable file names.
6483 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
6484 (AC_INIT): Use it.
6485 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
6486 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
6487 ac_pwd, and quote srcdir.
6488 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
6490 * doc/autoconf.texi: Fix some systematic formatting problems.
6491 ".)" needs a following @: if not at the end of a sentence, and
6492 similarly for "!)". "etc." should be preceded by a comma.
6493 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
6495 2005-03-22 Bruno Haible <bruno@clisp.org>
6497 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
6498 argument is often called 'build-aux'.
6500 2005-03-07 Stepan Kasal <kasal@ucw.cz>
6502 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
6503 macro AC_TRY_LINK is obsolete.
6504 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
6505 `AC_CONFIG_FILES'.
6507 2005-02-24 Stepan Kasal <kasal@ucw.cz>
6509 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
6510 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
6511 from a Common Lisp's `cl'.
6512 (AC_PROG_CXX): Behave according to the documentation: don't
6513 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
6514 make the variable CCC precious; use `cl.exe', not `cl'.
6516 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6517 Alexandre Duret-Lutz <adl@gnu.org>
6519 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
6520 /dev/null, as "configure" shouldn't read stdin, and this insulates
6521 us from problems (e.g., when testing for "cl"). Also, do this
6522 redirection before invoking "hostname" or "uname", and keep the
6523 original input stream available via...
6524 (AS_ORIGINAL_STDIN_FD): ... this new macro.
6525 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
6526 bother with "</dev/null" since it's now done at the top of
6527 'configure'.
6528 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
6529 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6530 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

6533 * tests/base.at (Input/Output): New test.
6535 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6537 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
6538 newline if neither \c nor -n work, as that would output two
6539 newlines. Prefer -n to \c. Reported by Stepan Kasal.
6541 2005-02-12 Stepan Kasal <kasal@ucw.cz>
6543 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
6544 This causes that any required macros inside will get before the if.
6545 * doc/autoconf.texi (autom4te.cache): A typo.
6547 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
6549 Undo previous change, except keep the change to
6550 lib/autoconf/programs.m4 that replaced grep with shell
6551 pattern-matching. This is because net-snmp configure reads stdin.
6552 Reported by Noah Misch.
6554 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
6556 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
6557 from /dev/null, as "configure" shouldn't read stdin, and this
6558 insulates us from problems (e.g., when testing for "cl").
6559 Suggested by Alexandre Duret-Lutz. Also, do this redirection
6560 before invoking "hostname" or "uname".
6561 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6562 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
6563 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
6564 "</dev/null" since it's now done at the top of 'configure'.
6565 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6566 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6567 Also, replace grep with shell pattern-matching, to save a process.
6569 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
6571 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6572 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
6573 avoid thinking that Allegro Common Lisp's "cl" command is a C++
6574 compiler.
6576 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
6578 * doc/autoconf.texi (Limitations of Usual Tools): Document that
6579 grep -q isn't portable. Improve grep -s explanation.
6580 Problem reported by Dan Manthey.
6582 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
6584 * doc/autoconf.texi (Special Shell Variables): Clarify
6585 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
6587 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
6589 * doc/autoconf.texi: Use @acronym for DJGPP.
6590 Fix some @code's that should have been @env's, and vice versa.
6591 Sort environment variable names.
6592 Mention that shells no longer inherit IFS.
6593 Don't recommend PATH_SEPARATOR=';' so strongly.
6594 Mention that $RANDOM might expand to the empty string.
6595 "symlink" and "soft link" -> "symbolic link".
6596 Improve mktemp description (reported by Bruno Haible).
6598 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
6600 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
6601 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
6602 Likewise.
6603 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
6604 Likewise.
6606 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
6608 * NEWS: Mention AT_COPYRIGHT.
6610 * tests/local.at (AT_CMP): Use diff directly on input files rather
6611 than copying them.
6613 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
6614 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
6616 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6617 and Paul Eggert <eggert@cs.ucla.edu>
6619 * tests/autotest.at (Empty test suite): New test.

6624 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6626 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
6627 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
6628 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
6629 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
6630 (Standard regular expressions): New test.
6631 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
6632 excess test name quoting.
6633 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
6634 CPPFLAGS to `configure' instead of setting it in `configure'.
6636 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
6637 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
6638 on some platforms.
6640 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
6641 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
6643 * tests/local.at (AT_CMP): New macro.
6644 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

6648 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
6649 * tests/c.at (Extensions): Do not exit early.

6669 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
6671 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
6672 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
6674 Try not to generated lines of unlimited length, as POSIX places a
6675 2047-byte limit on line length of portable text files.
6676 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
6677 Use newline as a separator, not space.
6678 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
6679 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
6680 space.
6682 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6684 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
6685 as_func_*. Add test to check whether positional parameters
6686 are restored after function return.
6688 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
6690 * doc/autoconf.texi (Special Shell Variables): Mention _,
6691 BIN_SH, DUALCASE. Say that variables other than "status" are safe
6692 if they contain a lower-case letter. The DUALCASE problem was
6693 reported by Ralf Wildenhues.
6695 * bin/autoconf.as: Don't exit with status 0 after write failure
6696 with --help or --version.
6697 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

6702 * doc/autoconf.texi (Limitations of Usual Tools):
6703 Unicos 9 sed limitations.
6704 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
6705 to get the option-enhanced interface on older Crays. Try ftn for
6706 Fortran 95 (newer Crays).
6708 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
6710 * man/Makefile.am (.x.1): Go back to the simple solution, but take
6711 care to echo the commands, so the user knows what's going on.
6712 Modified from a suggestion by Stepan Kasal.
6714 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
6715 with a cross reference. Derived from a suggestion by Bruce Korb.
6717 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
6719 * doc/autoconf.texi (config.status Invocation): Warn about
6720 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
6721 * doc/install.texi (Defining Variables): Likewise.
6722 Based on a proposed patch by Ralf Wildenhues.
6724 * man/Makefile.am (.x.1): Make sure the required generated files
6725 are up to date. Problem and original solution proposed by Stepan Kasal.
6726 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
6727 implicit-man-prerequisites): New rules, used by the above.

6733 2005-01-29 Stepan Kasal <kasal@ucw.cz>
6735 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
6736 Update the long comment explaining it.
6738 m4_require no longer writes an ``is required by'' line to the
6739 execution stack. It contains only one bit of non-redundant
6740 information: that the macro was required, not called. And even
6741 this bit is useless in most situations: have you ever met a macro
6742 which both calls and requires the same macro?
6744 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
6745 (_m4_defun_pro_outer): ... only via this macro, for the outermost
6746 macro.
6747 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
6748 (m4_expansion_stack_pop): Remove the misplaced comment.
6749 (m4_require): Don't put the ``is required by'' line to the
6750 execution stack; slightly improve the out-of-a-defun error message.
6751 (_m4_divert_grow): New macro, counter for the temporary diversions.
6752 (_m4_require_call): Use it.
6753 * tests/m4sugar.at (m4_require): Expect output without the
6754 ``is required by'' messages.
6756 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
6758 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
6759 rather than x for expr.
6761 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
6762 this is safe.
6763 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
6764 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

6775 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
6776 from masters, so that FileUtils.pm's update_file provide --force
6777 support.
6778 * bin/autoheader.in: Pass $force to update_file so that
6779 config.h.in is always recreated when --force.
6781 2005-01-24 Stepan Kasal <kasal@ucw.cz>
6783 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
6785 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
6787 * doc/autoconf.texi (Limitations of Builtins): Clarify that
6788 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
6790 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
6792 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
6793 Warn about newline stripping in `` and $(). Update Solaris
6794 version to 9.
6795 (Limitations of Builtins): Use expr "X...", not expr "x...", as
6796 X insulates us from future changes to Posix.
6797 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
6798 stripping.
6800 2005-01-19 Stepan Kasal <kasal@ucw.cz>
6802 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
6803 you cannot use AC_DEFINE to define macros containing `[' or `]'.
6805 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
6807 * doc/autoconf.texi (Limitations of Usual Tools): Document bug
6808 in Solaris 8 join. Problem reported by Tomohiro Suzuki on

6818 ulongval to be static, to avoid unwanted GCC warning. Problem
6819 reported by Michael Jennings via Daniel Reed; see
6820 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
6822 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
6824 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
6825 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
6826 datadir, infodir, and mandir. Adjust argument parsing code.
6827 (_AC_INIT_HELP): Update help text.

6829 new variables.
6831 2005-01-04 Noah Misch <noah@cs.caltech.edu>
6833 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
6834 not seem to work, assume it does set $(MAKE).
6835 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
6837 2005-01-03 Stepan Kasal <kasal@ucw.cz>
6839 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.
6841 2005-01-03 Stepan Kasal <kasal@ucw.cz>
6843 A cleanup of the diversion support in m4sugar.
6845 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
6846 (_m4_divert_n_stack): New macro; the expansion is

7164 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
7165 "char c = '\200';" rather than "char c = 0x80;" as the

7311 Version 2.59b.
7313 * README: Add advice about m4 1.4.2.
7315 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
7316 texinfo.tex for now (done by hand now).
7317 * Makefile.maint (wget_files, cvs_files):
7318 Remove ansi2knr.c; nobody uses it.
7319 (ansi2knr.c-url_prefix): Remove.
7320 (cvs-update): Fix test for failure. I don't know why it ever
7321 worked...
7323 * doc/autoconf.texi: Update URLs, some of which went stale.
7324 Use @uref rather than @href.
7326 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
7327 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
7329 * config/config.guess, config/config.sub, config/elisp-comp,
7330 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
7331 doc/fdl.texi, doc/standards.texi: Sync with master copy.
7333 * NEWS, TODO, configure.ac, bin/autoscan.in,
7334 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
7335 doc/install.texi, lib/Autom4te/Configure_ac.pm,
7336 lib/Autom4te/FileUtils.pm, lib/autoconf/general.m4,
7337 lib/autoconf/programs.m4, lib/autoconf/status.m4,
7338 lib/autotest/general.m4, lib/m4sugar/m4sh.m4,
7339 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
7340 tests/tools.at, tests/torture.at:
7341 Use "file name" rather than "filename" or "path",
7342 to be consistent with the terminology of the GNU coding standards.
7344 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
7346 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
7347 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
7348 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
7349 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
7351 More fixes to support spaces in the name of the build directory.
7352 This isn't a complete fix but it's an improvement.
7354 * bin/autoconf.as (autom4te_options): New var.
7355 Use it instead of appending to AUTOM4TE, so that we can allow
7356 spaces in the build directory's absolute name.
7357 * bin/autoheader.in ($autoconf): Allow spaces in file names.
7358 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
7359 AT_CHECK_NOESCAPE): Likewise.
7360 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
7361 main program): Likewise.
7363 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
7365 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
7366 From Ralf Corsepius in:
7367 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
7369 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
7371 * doc/autoconf.texi (Function Portability): Document isinf and
7372 and isnan. From a suggestion by Kevin Ryde.
7374 * lib/Autom4te/General.pm (END): Return correct exit status even
7375 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
7377 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
7379 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
7380 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
7381 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
7383 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
7385 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
7386 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
7387 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
7388 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
7389 * lib/autom4te.in (Automake-preselections): Preselect
7390 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
7392 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
7394 * lib/autom4te.in (Automake-preselections): Preselect
7395 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
7396 trace them.
7398 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
7400 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
7401 Tru64.
7402 * doc/autoconf.texi (Shellology): Mention BIN_SH.
7403 Document problem with "`""`" in pdksh POSIX mode.
7405 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
7407 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
7408 with pdksh, too. Problem reported by Patrick Welche via
7409 Gary V. Vaughan.
7410 * doc/autoconf.texi (Shellology): Note that set -o posix is
7411 useful for pkdsh, too.
7413 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
7415 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
7416 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
7417 Don't fail if ENV or BASH_ENV is readonly.
7418 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
7419 etc. are read only. Problem reported by Ludovic Courtes.
7421 2004-06-23 Noah Misch <noah@cs.caltech.edu>
7423 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
7424 zsh, disable GLOB_SUBST to avoid backslash handling problems.
7425 (trivial change)
7427 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
7429 * doc/autoconf.texi (File System Conventions): Warn about
7430 names like "aux". Problem reported by Eric Blake.
7432 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
7433 by zero instead of array size, so that we can use any arithmetic
7434 constant expression (instead of requiring an integer constant
7435 expression). This allows us to test expressions like DBL_MAX <
7436 LDBL_MAX, which didn't conform to the C standard using the old
7437 method.
7438 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
7439 now that we can do floating-point tests at compile time.
7441 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
7443 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
7444 and LDBL_EPSILON, as the resulting expression isn't an
7445 integer constant expression and violates the C standard.
7446 Problem reported by Nelson H. F. Beebe. Also, check
7447 for "L" suffix, and check that long double doesn't have
7448 worse range or precision than double, that mixed-mode
7449 arithmetic doesn't generate a diagnostic, that double
7450 constants fit in long double.
7452 2004-06-03 Kevin Ryde <user42@zip.com.au>
7454 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
7455 malloc(0) and realloc(NULL,size).
7457 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
7458 Bob Proulx.
7460 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
7462 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
7463 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
7464 by Jim Meyering.
7466 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
7468 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
7469 can be rewritten using if-then-else. Suggested by Bruno Haible.
7471 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
7473 * doc/autoconf.texi (testsuite Scripts): Fix typo.
7474 Problem reported by Stepan Kasal.
7476 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
7478 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
7479 change). Patch reported by Ralf Wildenhues in
7480 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
7482 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
7483 function F exists if the compiler and linker let you compile an
7484 expression like (F != 0). Recent versions of GCC optimize away
7485 the reference to F in that case, since every function address must
7486 be nonzero, so the link succeeds even if F does not exist.
7487 Problem reported by Manu in
7488 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
7490 * doc/autoconf.texi (Systemology): Standardize on the spelling of
7491 "Unix". Many uses changed.
7492 (Limitations of Builtins): Explain better why the ! command isn't
7493 portable.
7495 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
7497 * lib/autom4te.in (Automake-preselections): Preselect
7498 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
7500 2004-05-19 Kevin Ryde <user42@zip.com.au>
7502 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
7503 referencing AC_FUNC_STRERROR_R.
7505 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
7506 note pessimistic assumption when cross compiling.
7508 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
7510 * doc/autoconf.texi (Limitations of Make): Note that BSD make
7511 (until 2004) invoked subcommands with sh -e, contra POSIX.
7512 Reported by Kevin Ryde.
7514 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
7516 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
7517 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
7518 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
7519 `test -f " /usr/bin/grep"', which _always_ failed.
7520 (AC_PROG_SED): Ditto bogus PATH fix.
7521 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
7522 requires that grep correctly supports _multiple_ `-e' options, rather
7523 than stating only that grep should accept `-e'.
7525 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
7527 Port to C99, which requires that 'exit' be declared.
7529 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
7530 to ensure that stdlib.h is included.
7531 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
7532 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
7533 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
7534 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
7535 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
7536 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
7537 when using 'exit' in a test; C99 requires that 'exit' be declared.
7539 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
7541 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
7542 now prefers 'grep' implementations that accept -e.
7543 (Limitations of Usual Tools): Describe problems of traditional
7544 egrep and fgrep with long input lines, and of traditional grep
7545 with -e.
7546 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
7547 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
7548 All callers changed. Append /usr/xpg4/bin to the PATH, for
7549 Solaris.
7550 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
7551 the user with complaints about multiple -e options.
7552 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
7553 Define it with AC_PROG_GREP.
7554 * configure.ac (AC_PROG_GREP): Add.
7555 * lib/freeze.mk (GREP): New macro.
7557 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
7559 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
7560 a possible candidate only after all others fail, rather than
7561 consulting it first. This improves backward compatibility by
7562 better reflecting the way shell selection occurred in previous
7563 versions of Autoconf, and should help to avoid triggering latent
7564 problems in other packages, such as the one in Automake where zsh
7565 is not handled robustly:
7566 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
7567 Although it is not Autoconf's responsibility to work around
7568 problems in Automake, it nevertheless makes sense to avoid
7569 introducing unnecessary incompatibilites.
7571 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
7572 Gary V. Vaughan <gary@gnu.org>
7574 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
7575 how deeply nested we are when a suitable tool is found, set the
7576 ac_path_TOOL_found flag.
7577 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
7578 nested we are in this macro. Break out of all 3 nested loops if
7579 ac_path_TOOL_found is set.
7581 2004-04-21 Gary V. Vaughan <gary@gnu.org>
7583 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
7584 of the _AS_PATH_WALK loop too if GNU flavor is found.
7586 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
7588 * doc/autoconf.texi (Limitations of Make): Update documentation
7589 for `$<'. New entry `Long lines', based on a report from Simon
7590 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
7591 paragraph about DJGPP, based on a mail from Richard Dawe.
7593 2004-04-20 Paul Eggert <eggert@twinsun.com>
7595 * tests/c.at (C keywords): Don't assume that GCC supports
7596 "restrict" and "inline", as sufficiently-old GCC versions do not
7597 (also, GCC configured to be in pedantic C89 mode does not).
7598 Problem reported by Sumit Pandya in:
7599 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
7601 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
7602 consider -g to work if it generates warnings when plain compiles
7603 don't. Problem reported by Braden McDaniel in:
7604 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
7606 * doc/autoconf.texi (Slashes): New section, to document a problem
7607 reported by Jim Meyering in:
7608 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
7610 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
7611 linker output files before linking, to work around IRIX 6 linker bug.
7612 Problem reported by Rainer Orth in:
7613 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
7615 2004-04-20 Gary V. Vaughan <gary@gnu.org>
7617 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
7618 best tool so far counter rely on the tool path variable name to
7619 avoid checks for one tool being affected by the results of running
7620 the length check on a previous tool.
7622 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
7623 match expression argument, as different greps have different
7624 regular expression flavours.
7625 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
7626 literals.
7627 (AC_PROG_EGREP): Pass 'EGREP$'.
7628 (AC_PROG_GREP): Pass 'GREP$'.
7630 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
7632 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
7633 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
7635 2004-03-29 Paul Eggert <eggert@twinsun.com>
7637 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
7638 Types, Specific Compiler Characteristics, System Services,
7639 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
7640 etc. consistently instead of 'long', 'short', 'unsigned' etc.
7641 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
7642 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
7643 Likewise.
7644 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
7645 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
7646 AC_TYPE_OFF_T): Likewise.
7647 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
7648 Likewise.
7650 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
7651 pacify libtool 1.5.2. Fix quoting problems in sed command.
7653 2004-03-28 Paul Eggert <eggert@twinsun.com>
7655 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
7656 now defines HAVE_DECL_TZNAME if it is declared, when
7657 HAVE_STRUCT_TM_TM_ZONE is not defined.
7658 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
7659 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
7660 for HAVE_TZNAME.
7662 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
7664 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
7665 superfluous backslashing of quotes (") in sed expressions;
7666 thanks to Paul Eggert.
7668 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
7670 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
7671 Fortran compiler is ifort, also added pghpf; thanks to Nelson
7672 H. F. Beebe for the bug report.
7674 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
7676 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
7677 quoted -cmdline argument in Portland Group compiler (bug
7678 reported by Jeffrey J. Barteet).
7680 2004-03-25 Kevin Ryde <user42@zip.com.au>
7682 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
7683 (Run Time): ... here, where it's now mentioned.
7685 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
7687 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
7688 inherits from language Autoconf-without-aclocal-m4.
7689 (Customizing autom4te): Adjust example; the cache must now be
7690 disabled for language Autoconf-without-aclocal-m4.
7692 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
7693 Nathanael Nerode <neroden@twcny.rr.com>
7695 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
7696 AC_CHECK_TOOLS): Warn if a cross-tool is found without
7697 a prefix.
7698 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
7699 AC_CHECK_TARGET_TOOLS): New macros.
7700 * doc/autoconf.texi (Generic Programs): Document
7701 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
7702 AC_CHECK_TARGET_TOOLS, and warn for future changes
7703 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
7704 AC_CHECK_TOOLS.
7705 (Specifying Names): Document the reason for these future
7706 behavioral changes.
7707 * tests/mktests.sh: Do not generate tests for the
7708 new macros.
7709 * NEWS: Document these changes.
7711 * doc/autoconf.texi: Avoid macros with unbraced arguments,
7712 they make TeX hang up.
7714 2004-03-15 Paul Eggert <eggert@bogus.example.com>
7716 * NEWS: New macro AC_CHECK_ALIGNOF.
7717 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
7718 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
7719 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
7720 vowel.
7721 (AC_CHECK_ALIGNOF): New macro.
7722 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
7723 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
7724 those for sizeof.
7726 2004-03-03 Paul Eggert <eggert@twinsun.com>
7728 * bin/Makefile.am (edit): Don't use $< in a context where
7729 POSIX doesn't require support for it. Use $@.in instead.
7730 Problem reported by Anthony N. Frasso in
7731 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
7732 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
7734 2004-02-23 Gary V. Vaughan <gary@gnu.org>
7736 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
7737 from the next generation of Libtool.
7738 * lib/autom4te.in (Autoreconf-preselections): Ditto.
7740 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7742 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
7743 is not always thread-safe. Report from Nathanael Nerode.
7745 2004-02-18 Paul Eggert <eggert@twinsun.com>
7747 Fix a dependencies problem, stemming from a Autoconf 2.59 build
7748 problem on QNX reported by Stephen Rasku in
7749 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
7751 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
7752 $(m4sh_m4f_dependencies); this removes a FIXME.
7753 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
7754 (MAINTAINERCLEANFILES): Split into pieces,
7755 one per related section. Add $(srcdir)/wrapper.in.
7757 2004-02-09 Paul Eggert <eggert@twinsun.com>
7759 * doc/autoconf.texi (Setting Output Variables): Emphasize that
7760 AC_SUBST provides no portable way to escape literal newlines.
7762 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
7763 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
7764 Darwin uses -lcrt2.o and there's little point to cataloging all
7765 the system variants. Partial fix reported by Andreas Waechter in:
7766 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
7767 for bug reported by Nelson H. F. Beebe in:

7770 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
7772 * doc/autoconf.texi (AU_DEFUN): Fix English,
7773 suggested by Paul Eggert.
7774 * lib/autoconf/autoupdate.m4: Correct reference to
7775 acobsolete.m4, suggested by Alexandre Duret-Lutz.
7777 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
7779 * bin/autoupdate.in: Define __file__ so that warnings
7780 refer to the correct file.
7781 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
7782 the behavior of the third argument.
7783 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
7784 correctly the behavior of the third argument. Document
7785 what the three macros that AU_DEFUN defines do. Fix
7786 warning message when the third argument includes $0
7787 (reported by Alexandre Duret-Lutz).
7789 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
7790 Eric Sunshine <sunshine@sunshineco.com>
7791 Paul Eggert <eggert@twinsun.com>
7793 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
7794 (AS_INIT): Output shell initialization there. Removed optional
7795 parameter. Expand _AS_SHELL_FN_SPY.
7796 (AS_INIT_WITH_SHELL_FN): Removed.
7797 (_AS_SHELL_FN_SPY): New macro.
7798 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
7799 macros.
7800 (AS_SHELL_SANITIZE): Remove loop to find better shell
7801 and documentation for the parameter.
7802 (_AS_DETECT_BETTER_SHELL): Move it here.
7803 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
7804 (_AS_RUN): Move it here, support testing with eval.
7805 (AS_REQUIRE_SHELL_FN): Require shell functions when
7806 it is used.
7807 (_AS_LINENO_WORKS): Put around braces, we do not
7808 trigger the bash bug anymore.
7809 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
7810 use AS_INIT_WITH_SHELL_FN.
7811 * bin/autoconf.in, tests/wrapper.in: Regenerated.
7813 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
7815 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
7816 * doc/autoconf.texi: Don't say that the third parameter
7817 is broken.
7818 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
7819 (AU_DEFUN): Honor the third parameter, create autoupdate
7820 macros with AU_DEFINE.
7821 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
7822 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
7823 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
7824 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
7825 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

7829 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
7830 * lib/autoconf/status.m4: Remove FIXME.
7831 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
7832 that the macro is not present anymore in the updated
7833 configure.ac.
7834 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
7835 of autoupdate.
7837 2004-01-28 Paul Eggert <eggert@twinsun.com>
7839 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
7840 copyright years.
7841 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
7842 2003 (except 1997) to the list of copyright years. This undoes
7843 the 2003-05-22 change, which removed the older years from the list.
7844 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
7846 2004-01-27 Gary V. Vaughan <gary@gnu.org>
7847 Albert Chin-A-Young <china@thewrittenword.com>

7850 grep or ggrep program in PATH that accepts as long lines as
7851 possible.
7852 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
7853 AC_PROG_GREP.
7854 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
7855 egrep and fgrep respectively if $GREP -E/-F don't work.
7856 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
7857 _AC_PROG_GREP, and AC_PROG_SED.
7858 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
7859 longest input length accepted by a command.
7860 (AC_PROG_SED): Use it.
7861 * doc/autoconf.texi (Particular Programs): Document the changes.
7862 * NEWS: Updated.
7864 2004-01-27 Paul Eggert <eggert@twinsun.com>
7866 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
7867 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
7868 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
7869 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
7871 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
7872 bin/autoconf.in, config/Makefile.in, config/config.guess,
7873 config/config.sub, config/install-sh, config/mdate-sh,

7884 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
7885 tests/actypes.at: Regenerate and/or sync with original
7886 sources.
7888 2004-01-26 Paul Eggert <eggert@twinsun.com>
7890 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
7891 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
7892 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
7893 not <inttypes.h>. Problem reported by Tim Mooney in
7894 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
7895 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
7896 Likewise.
7898 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
7899 otherwise "make check" fails because it forbids cmp (I guess
7900 because cmp treats files as binary on DOS-like systems).
7902 * tests/mktests.sh: Update copyright date to 2004, since some tests
7903 have changed in 2004.
7905 2004-01-23 Gary V. Vaughan <gary@gnu.org>
7907 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
7908 non-truncating sed or gsed program in PATH.
7909 * tests/acprograms.at: Add it.
7910 * doc/autoconf.texi (Particular Programs): Document it.
7911 * NEWS: Updated.
7913 2004-01-15 Paul Eggert <eggert@twinsun.com>
7915 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
7916 -std1 disables some useful extensions on Tru64. Problem reported
7917 by N. Lichtmaier in
7918 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
7920 2004-01-14 Paul Eggert <eggert@twinsun.com>
7922 * doc/autoconf.texi (Programming in M4sh): Document that
7923 AS_MKDIR_P succeeds if the destination is a symbolic link
7924 to an existing directory.
7925 (Limitations of Usual Tools): Note that mkdir -p might not
7926 succeed on symlinks to directories.
7928 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
7930 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
7931 * bin/autoheader.in: Grammar fix in message.
7932 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
7933 Test for dir before calling mkdir -p. (trivial changes)
7935 2004-01-13 Eric Blake <ebb9@byu.net>
7937 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
7938 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
7940 2004-01-10 Jim Meyering <jim@meyering.net>
7942 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
7944 2004-01-09 Paul Eggert <eggert@twinsun.com>
7946 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
7947 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
7948 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
7949 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
7950 AC_COMPILE_IFELSE, since we now assume our caller invokes
7951 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
7952 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
7953 of AC_RUN_IFELSE; this avoids the warning mentioned above.
7954 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
7956 2004-01-07 Paul Eggert <eggert@twinsun.com>
7958 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
7959 `"'...'"`, as it's confusing (and I suspect it may not work on
7960 some platforms). The code was incorrect anyway, as it assumed
7961 that \$ evaluated to itself in that context. Reported by
7962 Alexandre Duret-Lutz.
7964 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
7966 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
7967 and _LT_AC_TAGCONFIG.
7969 2004-01-06 Paul Eggert <eggert@twinsun.com>
7971 * doc/autoconf.texi (One Macro Call): Fix an incorrect
7972 example, and add more examples. Reported by Eric Sunshine.
7974 2004-01-05 Paul Eggert <eggert@twinsun.com>
7976 * doc/autoconf.texi (Limitations of Usual Tools):
7977 Remove warning against "rm -fr" introduced yesterday; it
7978 was a false alarm.
7980 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
7981 autoscan, autoupdate, ifnames): Don't use chmod -w.
7982 * lib/Makefile.am (autom4te.cfg): Likewise.
7983 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
7984 "chmod -w".
7986 2004-01-04 Paul Eggert <eggert@twinsun.com>
7987 Paolo Bonzini <bonzini@gnu.org>
7989 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
7990 by doing lineno substitution only on lines containing "$LINENO".
7992 2004-01-04 Paul Eggert <eggert@twinsun.com>
7994 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
7995 Use "rm -f" to remove conftest.sed, not plain "rm".
7996 Bug reported by David Relson in
7997 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
7999 * Makefile.am (autom4te-update):
8000 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
8001 * Makefile.maint (my-distcheck, do-po-update): Likewise.
8002 * doc/autoconf.texi (Guidelines): Likewise.
8003 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

8008 * tests/Makefile.am (clean-local): Likewise.
8009 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
8010 srcdir): Likewise.
8011 * doc/autoconf.texi (Limitations of Usual Tools):
8012 Warn against "rm -fr".
8014 2004-01-03 Paul Eggert <eggert@twinsun.com>
8016 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
8017 -c -o might not work. From a suggestion by Kevin Ryde.
8018 (C Compiler, Generating Sources, Limitations
8019 of Usual Tools, Limitations of Make, Making testsuite Scripts):
8020 Don't put '-o' after non-options, as POSIX doesn't allow this.
8021 Mention that cc's name might be gcc or c89 or whatever.
8023 2004-01-04 Kevin Ryde <user42@zip.com.au>
8025 * doc/autoconf.texi: Add various further index entries.
8027 2003-12-29 Paul Eggert <eggert@twinsun.com>
8029 * bin/autoreconf.in (autoreconf_current_directory):
8030 Fix typo: mkdir without umask arg.
8032 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
8034 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
8035 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
8036 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
8037 explanation clearer.
8039 2003-12-24 Andreas Schwab <schwab@suse.de>
8041 * doc/autoconf.texi (Default Includes): Fix misspelling of
8042 AC_INCLUDES_DEFAULT.
8044 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
8046 * configure.ac: Test if sh -n works.
8047 * configure: Regenerate.
8048 * tests/atlocal.in: Store the result here.
8049 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
8050 tools.at, looking in atlocal's ac_cv_sh_n_works instead
8051 of explicitly testing.
8052 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
8053 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
8054 * tests/tools.at (Syntax of the shell scripts): Simplify
8055 using AT_CHECK_SHELL_SYNTAX.
8056 (Syntax of the Perl scripts): Remove definition of
8057 AT_CHECK_PERL_SYNTAX.
8059 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
8061 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
8062 stderr to /dev/null.
8063 * bin/autoconf.in: Regenerate.
8064 * bin/wrapper.in: Regenerate.

8068 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
8069 Extracted from AS_SHELL_SANITIZE.
8070 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
8071 macros.
8072 (AS_SHELL_SANITIZE): Move reinvocation code from
8073 _AS_LINENO_WORKS, use it to find out if shell
8074 functions work.
8075 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
8076 does not work.
8077 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
8078 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
8079 was called.

8088 * config/announce-gen (&print_locations, &print_signatures)
8089 (&sizes): New.
8090 Use them.

8092 them on the fly.
8094 2003-11-24 Akim Demaille <akim@epita.fr>
8096 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

8124 parameter of AU_DEFUN.
8125 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.

8129 the expanded body, consistently with other macros such as AC_USG.
8131 2003-11-17 Paul Eggert <eggert@twinsun.com>
8133 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
8134 into the initial confdefs.h, to work around a bug in NextStep 3.3
8135 patch 3 reported by Eric Sunshine.
8137 2003-11-15 Kevin Ryde <user42@zip.com.au>
8139 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
8140 than $target since the latter is not usual, add guidelines on when to
8141 use or not use the system type.
8143 2003-11-12 Derek Price <derek@ximbiot.com>
8145 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
8146 typo misrepaired by an auto-spellcheck.
8148 2003-11-12 Akim Demaille <akim@epita.fr>

8165 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE
8166 so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,
8167 and ac_abs_top_srcdir are absolute paths.

8174 2003-11-05 Kevin Ryde <user42@zip.com.au>

8181 handler return type, as per AC_TYPE_SIGNAL.

8193 computing the absolute path to d1 in the source hierarchy: it may
8194 not exist at all. So don't cd into it.

8318 Problems reported by Eric Sunshine.
8320 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
8322 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
8323 -mGLOB_options_string stuff for Intel ifc, which can cause

8347 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
8348 cache variable instead of $G77 to decide whether to include -O2,
8349 since $G77 is specific to Fortran 77.

8353 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
8354 free" flag. Re-order flags tested into rough order of popularity.
8356 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
8358 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
8359 arguments so that it can be used with syntax identical to
8360 AC_PROG_F77, and so that we can more easily decide to
8361 remove/deprecate the DIALECT optional argument in the future if it
8362 proves troublesome.
8363 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
8364 non-freeform-supporting compilers. Document freeform flags.

8378 2003-10-03 Akim Demaille <akim@epita.fr>
8380 * configure.ac: Quotation and formatting changes.

8428 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
8429 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
8430 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
8431 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
8433 2003-09-26 Akim Demaille <akim@epita.fr>
8435 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
8436 directory for AC_CONFIG_COMMANDS' first argument exists.
8437 This makes valid the invocation of _AC_SRCPATH that follows.
8438 Reported by Eric Sunshine.
8439 * doc/autoconf.texi (Configuration Commands): Adjust.
8441 2003-09-26 Akim Demaille <akim@epita.fr>
8443 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
8444 Reported by Ralf Corsepius.

8448 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
8449 arguments.
8450 Actually, use AU_ALIAS.
8451 From Bruno Haible.

8460 2003-09-26 Akim Demaille <akim@epita.fr>
8462 The test suite are sometimes assigning timings incorrectly.
8463 Reported by Henk Krus.
8464 Diagnosed by Nicolas Joly.
8466 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
8467 AT_help_all.
8468 Instead of making AT_help a sequence of assignments to grow
8469 $at_help_all, just make AT_help_all be the growing contents of
8470 $at_help_all, and make a single assignment in...
8471 (AT_INIT): here.
8472 (at_times_skip): Flip the meaning and rename as...
8473 (at_times_p): this.
8474 (AT_INIT): When summarizing the test that ran, remove
8475 $at_times_file after use, and check it is present before trying to
8476 use it.
8478 2003-09-25 Akim Demaille <akim@epita.fr>
8480 Version 2.57d.
8482 * bin/Makefile.am (edit): Handle '@configure_input@'.
8483 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
8484 (ifnames): chmod -w.
8485 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
8486 executables, not bin/ executables! Otherwise all the magic needed
8487 to find non installed files is turned off. This caused a failure
8488 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
8489 as found in its environment (sent by tests/autoreconf): pointing
8490 to bin/autom4te that could not find its files.
8491 * tests/mktests.sh: Force the replacement of generated files, for
8492 the sake of "mv" program that are interactive when overwriting a
8493 -w file.

8499 versus test -L issues.
8501 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
8502 Paul Eggert <eggert@twinsun.com>
8504 Trivial change to support GCC's configuration procedure.
8505 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
8506 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
8507 about inconsistency if the preprocessor is set to give errors for
8508 any warning.
8509 * doc/autoconf.texi (C Compiler Characteristics): Document this.
8511 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

8535 From Peter Hendrickson.
8537 2003-09-10 Akim Demaille <akim@epita.fr>
8539 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
8540 willing to edit the output files.
8542 2003-09-10 Akim Demaille <akim@epita.fr>
8544 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
8545 and AC_FC_FREEFORM.
8546 * tests/mktests.sh: Skip AC_FC_SRCEXT.
8547 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

8563 Improve the accuracy of the wording about obsolescence.
8564 From a suggestion by Ian Lance Taylor in
8565 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
8567 2003-09-05 Paul Eggert <eggert@twinsun.com>
8569 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
8570 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
8572 2003-09-04 Akim Demaille <akim@epita.fr>
8574 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
8575 AC_FUNC_WAIT3.
8577 2003-09-04 Akim Demaille <akim@epita.fr>
8579 * bin/autom4te.in: Use &fatal where more appropriate than &error.
8580 (freeze): When exiting, use $exit_code.
8581 * lib/autoconf/fortran.m4: Comment changes.
8583 2003-09-04 Akim Demaille <akim@epita.fr>
8585 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
8587 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
8589 Add support for newer Fortran dialects. The F77 interface is
8590 unchanged, and continues to support Fortran 77. New FC macros
8591 correspond to all the old F77 macros, with output variables FC,
8592 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
8593 available dialect, but older dialects can be specified. There are
8594 new macros AC_FC_SRCEXT to set the source extension, and
8595 AC_FC_FREEFORM to accept free-form source files.
8597 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
8598 New macros.
8599 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

8615 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
8616 Rewrite in terms of the above.
8617 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
8618 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

8622 2003-09-02 Paul Eggert <eggert@twinsun.com>
8624 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
8625 Document problems with timestamp resolution that 'make', 'cp -p', and
8626 'touch -r' have.
8628 2003-08-27 Akim Demaille <akim@epita.fr>
8630 * tests/m4sugar.at (cross_warning): Make sure to enable the
8631 output, so that we can track spurious m4sugar output.
8632 * tests/local.at: Require 2.57.
8633 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
8634 are defaulted by AT_CHECK anyway.
8635 Use AT_CHECK_AUTOM4TE.
8636 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
8637 missing dnl.
8639 2003-08-27 Akim Demaille <akim@epita.fr>
8641 * bin/autoheader.in: Issue the "Using auxiliary..." message only
8642 when -Wobsolete is set.

8681 * Makefile.maint (local-check): Rename as...
8682 (local-checks-available): this.
8683 (local-check): New.
8685 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
8686 * configure.ac: Require Automake 1.7.6.
8688 2003-08-22 Akim Demaille <akim@epita.fr>
8690 Output stack traces in warnings.
8692 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
8693 Replace the former...
8694 (m4_warn): Pass the call stack to _m4_warn.
8695 * bin/autom4te.in: Adjust to output the call stack.
8696 * tests/m4sugar.at (m4@&t@_warn): Adjust.
8698 2003-08-22 Akim Demaille <akim@epita.fr>
8700 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
8701 * bin/autom4te.in: Adjust.
8703 2003-08-21 Akim Demaille <akim@epita.fr>
8705 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
8706 (&verbose): Remove.
8707 (&getopt): Adjust the note and verb channels, depending upon
8708 --verbose.
8709 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
8710 * bin/autoupdate.in: Adjust.
8711 Use &verb, not &verbose.
8713 2003-08-21 Akim Demaille <akim@epita.fr>
8715 * bin/autoheader.in (&parse_args): Use &parse_warnings and
8716 &parse_WARNINGS.
8717 ($help): Use Autom4te::ChannelDefs::usage.
8718 * bin/autoscan.in: Use Autom4te::ChannelDefs.
8719 * lib/Autom4te/General.pm: Don't export error: you don't own it.
8721 2003-08-21 Akim Demaille <akim@epita.fr>
8723 First stab at preserving warnings between calls to autom4te,
8724 including when the cache is used.
8726 There are still several issues: (i) there are too many runs of m4
8727 (one for include, one for warnings, and some more), (ii) warnings
8728 spreading on several lines are not handled gracefully, (iii) the
8729 code meant to have the call stack display for errors does not work
8730 (its handling should move from m4 to autom4te).
8732 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
8733 Use them.
8734 (@preselect): Add m4_warn.
8735 ($exit_status): Remove, use $exit_code.
8736 ($help): Use Autom4te::ChannelDefs::usage.
8737 (&handle_m4): No longer define the m4_warnings.
8738 At each run, extract and report the warnings.
8739 Always cache the result, including if the exit status is on
8740 failure, since if nothing changes, we should result in the same
8741 failure, hence we can use the cache.
8742 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
8743 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
8744 Remove.
8745 (m4_warn): Redefine as a do-nothing: it is its invocation that
8746 matters, as warnings are now reported via traces.
8747 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
8748 the contents of m4_warn: make it _call_ m4_warn, so that tracing
8749 the latter reveals calls to the former.
8751 Adjust the tests.
8753 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
8755 2003-08-21 Akim Demaille <akim@epita.fr>
8757 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
8758 Use them.
8760 2003-08-21 Akim Demaille <akim@epita.fr>
8762 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
8763 forward order.
8764 * lib/Autom4te/ChannelDefs.pm: Doc typos.
8765 (&parse_warnings): Accept a list of warning requests.
8766 (&usage): Return a string, not a side effect.
8767 (cross): New warning category.
8769 2003-08-21 Akim Demaille <akim@epita.fr>
8771 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
8772 (&require_configure_ac): Accept an optional directory argument.
8773 ($configure_ac): Remove.
8774 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
8775 (&catfile): Remove.
8776 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
8777 * bin/autoscan.in: Adjust.
8779 2003-08-20 Akim Demaille <akim@epita.fr>
8781 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
8782 Reported by Alexandre Duret-Lutz.
8784 2003-08-20 Akim Demaille <akim@epita.fr>
8786 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
8787 * bin/autom4te: Adjust.
8788 In particular, be Autoconf tools are really silent when properly
8789 working, bind the verbosity of the 'note' channel to $verbose.
8790 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
8791 (&xsystem, &contents): Remove, since they are exported by...
8792 * lib/Autom4te/FileUtils.pm: this.
8793 More perldoc.
8794 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
8795 * lib/Autom4te/FileUtils.pm: here.
8797 2003-08-20 Akim Demaille <akim@epita.fr>
8799 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
8800 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
8801 from CVS Automake.
8803 2003-08-20 Akim Demaille <akim@epita.fr>
8805 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
8806 (autom4te-update): New.
8807 * Makefile.cfg (update): Bind autom4te-update.

8821 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
8823 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
8825 * lib/autom4te.in (Automake-preselections): Preselect
8826 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
8827 and m4_sinclude.
8829 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>

8852 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
8853 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
8854 shorter column three. Add DESCRIPTION to log file content.
8856 2003-08-13 Derek Price <derek@ximbiot.com>
8858 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
8859 output.
8861 2003-08-12 Derek Price <derek@ximbiot.com>
8863 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
8864 (AT_CHECK_NOESCAPE): Move core functionality to...
8865 (_AT_CHECK): ...this new macro.
8867 2003-08-07 Derek Price <derek@ximbiot.com>
8869 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
8870 (AT_CHECK_NOESCAPE): ...to this new macro.
8872 2003-07-31 Paul Eggert <eggert@twinsun.com>
8874 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
8875 in Bash 2.01. Problem reported by Brian Gough in
8876 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
8878 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
8880 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
8881 -lcrt1.o, for OS X. (trivial change)
8883 2003-07-07 Paul Eggert <eggert@twinsun.com>
8885 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
8886 inside '#ifndef __cplusplus'. Problem reported by
8887 Bob Friesenhahn.
8889 2003-07-06 Bill Clarke <llib@computer.org>
8891 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
8892 'long', not 'int', for benefit of Sun's recent C++ compilers
8893 (trivial change). See:
8894 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
8895 (This really should be 'intptr_t', not 'long', but that would
8896 take more work.)
8898 2003-06-25 Akim Demaille <akim@epita.fr>
8900 * lib/Makefile.am (autom4te.cfg): Make it read only.
8901 Depend on Makefile since it contains substitutions.
8902 From Paolo Bonzini.
8903 * lib/autom4te.in (args): Add local.at? for Autotest args.
8904 This change was made on autom4te.cfg which is generated.
8905 Reported by Raja R. Harinath.
8907 2003-06-25 Akim Demaille <akim@epita.fr>
8909 * doc/autoconf.texi (Header Portability): sys/mount.h.
8910 From Gareth McCaughan.
8912 2003-06-23 Akim Demaille <akim@epita.fr>
8914 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
8915 not all of them. This fixes 1. the fact that when testing
8916 Autoconf there are many many config.log, 2. the incorrect use of
8917 top_srcdir to find config.log.
8918 Don't mix the detailed output of failed test with the summary of
8919 failures. Rather, append detailed log afterwards.
8921 2003-06-23 Akim Demaille <akim@epita.fr>
8923 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
8924 always run: output config.log on $at_group_log.
8926 2003-06-23 Akim Demaille <akim@epita.fr>
8928 * tests/torture.at (#define header templates): Don't use quotes in
8929 C++ comments as it puzzles Emacs' sh font-lock-mode.
8931 2003-06-23 Akim Demaille <akim@epita.fr>
8933 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
8934 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
8935 * tests/atspecific.m4: Rename as...

8938 * tests/local.at: here.
8939 * tests/Makefile.am: Adjust.
8940 * doc/autoconf.texi (testsuite Scripts): Adjust.
8942 2003-06-21 Kevin Ryde <user42@zip.com.au>
8944 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
8945 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
8946 ensuring we add -std1 for full-ANSI.
8948 * doc/autoconf.texi (hdrindex): New macro.
8949 Add index entries for portability of various standard header files.
8951 2003-06-20 Akim Demaille <akim@epita.fr>
8953 * configure.ac: Bump to 2.57b.
8955 2003-06-20 Akim Demaille <akim@epita.fr>
8957 Version 2.57a.
8959 2003-06-20 Akim Demaille <akim@epita.fr>

8962 Reported by Marc Espie as PR/233.
8964 2003-06-20 Akim Demaille <akim@epita.fr>
8966 * lib/autotest/general.m4: Use at_times_file only if used.
8967 From Nicolas Joly.

8971 * config/config.guess, config/config.sub, config/elisp-comp,

8973 Update from masters.
8975 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
8977 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
8978 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
8979 (TEST_SCRIPT): New diversion.
8980 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
8981 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
8982 (AT_INIT): Support for expected failures.
8984 2003-06-02 Akim Demaille <akim@epita.fr>
8986 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
8987 changes.
8988 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
8989 Autoconf nor Automake.
8990 (&contents): New, from Automake.
8991 PODify.
8993 2003-05-28 Paul Eggert <eggert@twinsun.com>
8995 * NEWS, doc/autoconf.texi (Particular Functions),
8996 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
8997 is the inverse of localtime.
8999 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
9001 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
9002 (handle_exec_errors): New function. Work around $! being
9003 altered by WEXITSTATUS.
9004 (xqx, xsystem): Use handle_exec_errors.
9006 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
9008 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
9009 Do not call `_exit()', simply modify `$?'.
9010 (xsystem): Reset $! before running system, and check it afterward.
9011 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
9012 63 for version mismatches.
9014 2003-05-23 Akim Demaille <akim@epita.fr>
9016 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
9017 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
9018 the middle of a line).
9019 * lib/m4sugar/m4sugar.m4: Likewise.
9020 Remove useless spaces in comments.
9022 2003-05-23 Akim Demaille <akim@epita.fr>
9024 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
9025 exit 63, so that we (or Automake's "missing") can tell the
9026 difference with a plain failure.
9027 * doc/autoconf.texi (Notices): Adjust.
9029 2003-05-23 Akim Demaille <akim@epita.fr>
9031 * Makefile.am, bin/Makefile.am, config/Makefile.am,
9032 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
9033 White spaces cleanup.
9035 2003-05-22 Jim Meyering <jim@meyering.net>
9036 Paul Eggert <eggert@twinsun.com>
9038 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
9039 Remove `#include <stdlib.h>' from the list; we should never
9040 make confdefs.h include <stdlib.h> or <cstdlib>, because the
9041 resulting namespace pollution would cause other tests to fail.
9042 Configure scripts run with some older versions of g++ and HP's
9043 aCC would fail due to such an #include. Problems reported by
9044 Matthew Mueller in <http://bugs.debian.org/120704> and by
9045 Keith Bostic in
9046 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
9047 In the test, use the test declaration before including <stdlib.h>,
9048 as that's closer to how it'll be used.
9050 2003-05-23 Akim Demaille <akim@epita.fr>
9052 * doc/autoconf.texi (Header Portability): ucred.h.
9053 From Ian Redfern.
9055 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
9057 Overhaul Autotest's logging: generate separate log files
9058 in testsuite.dir/NNN/testsuite.log, and append them to
9059 testsuite.log instead of re-running the test verbosely.
9061 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
9062 file descriptor, write 0 to at_status_file instead of setting
9063 at_status=0, initialize some new variables (at_status_file,
9064 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
9065 to rerun the tests, instead append the at_group_log to the
9066 at_suite_log when a test fails.
9067 (AT_SETUP): pipe the test case's output into at_tee_pipe,
9068 with the AS_MESSAGE_LOG_FD redirected to stdout.
9069 (AT_CLEANUP): save the output status in $at_status_file
9070 and restore it, redirect the AS_MESSAGE_LOG_FD back to
9071 its original place.
9072 (AT_CHECK): since tests are run with a redirected stdout,
9073 and used to be re-run in verbose mode, turn some $at_verbose
9074 into echo, and don't redirect the output of testing stdout
9075 and stderr.
9077 * lib/autotest/autoconf.texi (testsuite Scripts): Update
9078 the name of the debugging directory and information about
9079 its contents.
9081 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
9083 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
9084 parameter.

9159 2003-05-17 Akim Demaille <akim@epita.fr>

9196 and truncate.
9198 2003-05-06 Akim Demaille <akim@epita.fr>
9200 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
9201 longer updates aclocal.m4 if useless, (ii) if a file m4_included
9202 by aclocal.m4 is changed it might require the importing of another
9203 m4 extension file, i.e., aclocal must be run.
9205 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
9206 (&parse_args): Use --force with aclocal if required and supported.
9207 (&autoreconf_current_directory): Use &run_aclocal.

9214 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
9215 argument instead of a file name, so that the request file remains
9216 open during the whole autom4te run.
9217 ($icache_file): New.
9218 (&freeze): Lock the $icache_file.
9220 2003-04-29 Derek Price <derek@ximbiot.com>
9222 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
9223 seperator with m4_append_uniq(). It doesn't work.
9224 (AT_CLEANUP): Add `;' to end of at_help_all.
9225 (AT_INIT): Allow --keywords to be specified more than once. When
9226 grepping $at_help_all for keywords, use the field and keyword
9227 seperators to ensure a complete keyword match. Alter at_prev handling
9228 to support the new --keywords behavior.
9230 2003-04-27 Karl Berry <karl@freefriends.org>
9232 * doc/autoconf.texi: Make the dir entries in the autoconf manual
9233 align better with others. I also made some of the individual
9234 entries on one line, for brevity and to make it easier for me to
9235 sort my dir-example file in the Texinfo distribution :).
9237 2003-04-12 Jim Meyering <jim@meyering.net>

9302 header causes problems.
9304 2003-03-28 Akim Demaille <akim@epita.fr>
9306 * tests/torture.at (Configuring subdirectories): Require aclocal
9307 1.4, otherwise the test fails, as it does support configure.ac.
9308 This fixes the "test 40 failed" bug reports.
9310 2003-03-28 Akim Demaille <akim@epita.fr>
9312 * doc/autoconf.texi (C Compiler): `#line' portability.
9313 From Paul Eggert and Nelson H. F. Beebe.
9315 2003-03-27 Derek Price <derek@ximbiot.com>
9317 * lib/autotest/general.m4: Eliminate main loop and reorganize test
9318 layout in order to allow scripting around test groups.
9320 2003-03-27 Derek Price <derek@ximbiot.com>
9322 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
9323 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
9324 use new diversions in preparation for accepting new arguments and

9330 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
9331 obsolete AC_HELP_STRING.
9332 (AC_HELP_STRING): AU_DEFUN to...
9333 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
9334 * tests/m4sh.at (AS_HELP_STRING): New test.
9336 * tests/acgeneral.at: Regenerated.
9338 2003-03-26 Derek Price <derek@ximbiot.com>
9340 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
9341 sense. Verbosify the diversion definitions comment.
9343 2003-03-26 Derek Price <derek@ximbiot.com>
9345 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

9377 * doc/autoconf.texi (Limitations of Make): Remove the section
9378 about `$<' in inference rules, it was a bogus interpretation of
9379 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
9380 Tru64 make in the "target lookup" section.
9381 (Automake): Automake 1.5+ no longer requires special tools to be
9382 present on the developer's host.
9384 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
9386 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
9387 to a shell that can handle redirection or quoting correctly.
9388 Override SHELL with the shell detected by configure.
9389 Use of $^O suggested by Tim van Holder.
9390 * bin/autom4te.in (BEGIN): Likewise.
9391 * bin/autoreconf.in (BEGIN): Likewise.
9392 * bin/autoscan.in (BEGIN): Likewise.
9393 * bin/autoupdate.in (BEGIN): Likewise.
9394 * bin/ifnames.in (BEGIN): Likewise.
9396 * bin/ifnames.in: Add final newline to help and version messages.
9398 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
9399 to cope with DOS-style absolute paths, when constructing
9400 ${ac_make}.
9402 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
9403 When constructing paths with IFS=:, quote the path. If we're
9404 constructing a DOS-style absolute path, we don't want to split it
9405 on the colon.
9407 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
9408 in description.
9410 2003-02-25 Pavel Roskin <proski@gnu.org>

9418 2002-09-01 patch by replacing "test -n" with "test -z".
9419 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
9420 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
9422 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
9423 to fix a mismatch between example and discussion.
9425 2003-02-24 Kevin Ryde <user42@zip.com.au>
9427 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
9428 format starting with "-".
9430 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9432 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
9433 is not portable inside Makefile.
9435 2003-02-20 Akim Demaille <akim@epita.fr>
9437 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
9438 compiler says yeah, but preproc says nope, compiler is right.
9439 Conversely, prompt the reader to send a bug report to the
9440 maintainers of the package, not of Autoconf.
9442 2003-02-20 Klee Dienes <kdienes@apple.com>
9444 * bin/autoreconf.in (autoreconf_current_directory): Properly
9445 handle an empty aclocal.m4.

9450 $ac_prefix_program.
9451 From Larry Jones.
9453 2002-12-23 Paul Eggert <eggert@twinsun.com>
9455 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
9456 innocuous variant befor including <limits.h> or <assert.h>. This
9457 works around a bug reported by Albert Chin: HP-UX 11i
9458 (and earlier versions) have a <limits.h> that declares
9459 gettimeofday and many other functions.
9461 2002-12-03 Paul Eggert <eggert@twinsun.com>
9463 Version 2.57.
9465 * NEWS, configure.ac: Update version.
9467 * doc/fdl.texi: Upgrade to FDL version 1.2.
9469 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
9470 nontrivially in main's body, so that f's external declaration is
9471 not optimized away in AIX. This should fix the bug reported by
9472 Martin Frydl in
9473 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
9475 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
9476 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
9477 defined, to support freestanding compilers. This should fix the
9478 bug reported by Momchil Velkov in
9479 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
9481 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
9482 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
9483 obsolete AC_CHECK_TYPE. The missing empty arg was reported
9484 by Simon Josefsson in

9487 * Makefile.maint (www-gnu): New macro.
9488 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
9489 the location has moved.
9491 2002-12-02 Martin Frydl <martin@systinet.com>
9493 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
9494 \(.*\) match is too long and there is something more to be checked.
9495 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
9497 2002-11-15 Akim Demaille <akim@epita.fr>
9499 Version 2.56.
9501 * config/install-sh: chmod +x.
9502 From Paul Eggert.
9503 * config/move-if-change: Indenting changes.
9504 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
9505 * configure.ac (AM_INIT_AUTOMAKE): here.
9506 Require 1.7.1.
9508 2002-11-14 Akim Demaille <akim@epita.fr>
9510 Version 2.55.
9512 * config/config.guess, config/config.sub, config/install-sh:
9513 Update from masters.
9515 2002-11-14 Akim Demaille <akim@epita.fr>
9517 * Makefile.maint: Sync with Bison, i.e.:
9518 (po-check): Scan .l and .y files instead of the
9519 .c and the .h files that they generate. This fixes the bug
9520 reported by Tim Van Holder in:
9521 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
9522 Look for N_ as well as for _. Try to avoid matching #define for
9523 N_ and _.
9524 From Paul Eggert.
9526 2002-11-14 Akim Demaille <akim@epita.fr>
9528 * doc/autoconf.texi (C Compiler): Compiling several files at once.
9529 From Paul Eggert and Albert Chin-A-Young.
9531 2002-11-14 Akim Demaille <akim@epita.fr>
9533 * doc/autoconf.texi (C Compiler): Solitary backslashes.
9534 From Paul Eggert and Albert Chin-A-Young.
9536 2002-11-14 Kevin Ryde <user42@zip.com.au>
9538 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
9539 than assigning in main, to avoid HP cc +O3 optimizing it away.
9541 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
9543 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
9544 option. Process --recheck after parsing all options. Pass -q
9545 option to configure on --recheck.
9546 (AC_OUTPUT): Pass -q from configure to config.status.
9547 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
9548 arguments to record.
9549 * doc/autoconf.texi (config.status Invocation): Document
9550 config.status -q option.
9552 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
9554 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
9555 Makefile.in if Makefile.am exists.
9556 (output): Strip `.am' from Makefiles. Don't
9557 output AC_CONFIG_FILES if no Makefiles were found.
9559 2002-11-07 Akim Demaille <akim@epita.fr>
9561 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
9562 (local_updates): New.
9563 * Makefile.maint: Update, from CVS Bison.
9564 (local_updates): New.
9566 2002-11-06 Akim Demaille <akim@epita.fr>
9568 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
9569 declaration in extern "C" too.
9570 Reported by Roberto Bagnara.
9572 2002-11-06 Akim Demaille <akim@epita.fr>
9574 * tests/torture.at (Configuring subdirectories): Don't use grep
9575 -w.
9576 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
9577 Reported by Ezra Peisach.
9579 2002-11-05 Akim Demaille <akim@epita.fr>
9581 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
9582 Remove.
9583 We _have_ to stop using the old compatibility scheme that tried to
9584 avoid useless backslashes because Libtool 1.4.3 contains a
9585 AC_DEFINE([error_t], [int],
9586 [Define to a type to use for \`error_t' if it is not
9587 otherwise available.])
9588 We _have_ to quote the single quote and backslashes with \. The
9589 old compatibility scheme saw that ` was backslashed, and therefore
9590 did not quote the single quote. Hence before this patch, Autoconf
9591 was not compatible with Libtool.
9593 2002-11-04 Paul Eggert <eggert@twinsun.com>
9595 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
9596 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
9597 LC_NAME, LC_PAPER, LC_TELEPHONE.
9598 * doc/autoconf.texi (Special Shell Variables): Mention those vars.
9600 2002-11-04 Akim Demaille <akim@epita.fr>
9602 Version 2.54c.
9604 * Makefile.maint (update, cvs-update, po-update, do-po-update):
9605 New.
9606 * config/texinfo.tex: Update.
9608 2002-11-03 Akim Demaille <akim@epita.fr>
9610 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
9611 from...
9612 (&autoreconf): here.
9613 ($help, $make, &parse_args, &autoreconf_current_directory):
9614 Support -m/--make.
9615 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9617 2002-10-31 Bruno Haible <bruno@clisp.org>
9619 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.
9620 Change name of cache variable to ac_cv_func_malloc_0_nonnull.
9621 (AC_FUNC_MALLOC): Change description of HAVE_MALLOC macro.
9622 (_AC_FUNC_REALLOC_IF): Change message. Change name of cache variable
9623 to ac_cv_func_realloc_0_nonnull.
9624 (AC_FUNC_REALLOC): Change description of HAVE_REALLOC macro.
9626 2002-10-31 Akim Demaille <akim@epita.fr>
9628 The test suite was no longer checking for trailing envvars and files.
9630 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
9631 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
9633 2002-10-31 Akim Demaille <akim@epita.fr>
9635 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
9636 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
9637 Make variable, not a shell variable.
9638 Suggested by Bruno Haible.
9640 2002-10-31 Akim Demaille <akim@epita.fr>
9642 * bin/autom4te.in (load_configuration): Reject #args out of any
9643 language.
9645 2002-10-31 Akim Demaille <akim@epita.fr>
9647 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
9648 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
9649 (_AC_RUN_IFELSE): Use it.
9650 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
9651 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
9652 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
9653 inline it.
9655 2002-10-30 Akim Demaille <akim@epita.fr>
9657 * bin/autom4te.in (&parse_args, $help): Support --no-cache.

9923 2002-10-22 Akim Demaille <akim@epita.fr>

9934 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

9978 2002-10-16 Akim Demaille <akim@epita.fr>
9980 Because of caching, some files that no longer exist and are no
9981 longer required can still cause errors.
9982 Reported by Alexandre Duret-Lutz.
9984 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
9985 to frozen files in @ARGV, as @ARGV must remain being a list of

9988 (&freeze): Use &error.
9989 (&up_to_date): If a file that was included according to the cache
9990 is no longer there, then the output is out dated.

9992 --force is given.

9998 * bin/autoupdate.in (&parse_args): Kill old options.
9999 * bin/autoreconf.in (&parse_args): Remove dead options.
10000 Factor some code.
10001 (&autoreconf): Report the directories we enter *and leave*, so
10002 that error messages can be easily located, and use GNU Make
10003 format, so that Emacs' compile mode understands us.
10004 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
10005 if some file was changed instead of `print'.
10006 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

10039 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
10040 file name to enable parallel executions.
10041 From Sam Varshavchik.
10043 2002-10-08 Akim Demaille <akim@epita.fr>
10045 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
10046 aclocal invocation, as Gettext macros might not be visible to
10047 aclocal.
10048 Instead of blindly running autopoint, scan configure.ac (not the
10049 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
10050 Reported by Paul D. Smith.
10052 2002-10-08 Paul Eggert <eggert@twinsun.com>
10054 Work around problems found when POSIXLY_CORRECT=1 is set.
10055 None of this seems to have anything to do with POSIX, really,
10056 but it's how Perl getopt works.
10057 * bin/autom4te.in (parse_args): Configure GetOpt with
10058 "permute", too.
10059 * doc/autoconf.texi (Invoking autom4te):

10080 2002-09-28 Akim Demaille <akim@epita.fr>
10082 * tests/torture.at (Configuring subdirectories): Be robust to
10083 users who use config.site to require for a cache: in this case,
10084 the two last configure runs, using two different sets of
10085 arguments, trigger a legitimate error.
10087 2002-09-28 Akim Demaille <akim@epita.fr>
10089 * tests/m4sh.at (Functions Support, Functions and return Support):
10090 New.

10098 * doc/autoconf.texi (Installation Directory Variables): Adjust.
10100 2002-09-28 Akim Demaille <akim@epita.fr>
10102 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
10103 (tm_zone): Move their rules to...
10104 * lib/autoconf/types.m4: here, using AN_ macros.
10105 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
10106 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
10107 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

10120 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
10121 (.m4.m4f): Don't pass --prepend-include, since that's done by
10122 tests/autom4te itself.
10123 * lib/autoscan/Makefile.am: Include freeze.mk.
10124 (autoscan.list): New target --this file is no longer a source.
10125 (autoscan.pre): New file.
10127 2002-09-28 Akim Demaille <akim@epita.fr>
10129 * bin/autoscan.in (@kinds): Make them singular.
10130 Adjust all uses.
10131 (&init_tables): When --debug, report the list of rules to ease
10132 tracking changes in autoscan.list.
10133 * lib/autoscan/autoscan.list (function): Strip comments, sort.
10135 2002-09-28 Akim Demaille <akim@epita.fr>

10141 * bin/autoscan.in (&init_tables): Adjust.
10143 2002-09-28 Akim Demaille <akim@epita.fr>
10145 * lib/autoscan/functions, lib/autoscan/headers,
10146 * lib/autoscan/identifiers, lib/autoscan/makevars,
10147 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
10148 `functions' line is now prefixed with `function:'.
10149 * bin/autoscan.in (&init_tables): Adjust.
10151 2002-09-28 Akim Demaille <akim@epita.fr>
10153 From now on, autoscan files must always map a macro name to a
10154 word: there is no `default' macro for autoscan.
10156 * bin/autoscan.in (&init_tables): Reject entries with no macro at
10157 all.
10158 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
10159 explicit.
10161 2002-09-28 Akim Demaille <akim@epita.fr>
10163 * bin/autoscan.in (%c_keywords): Remove.
10164 (&used): Keep only track of the words we might be interested in.
10165 (&output_kind): It is no longer needed to look for non active
10166 checks.
10168 2002-09-27 Akim Demaille <akim@epita.fr>
10170 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
10171 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
10172 * lib/autoscan/functions: Adjust.
10173 * doc/autoconf.texi (Particular Functions): Adjust.
10175 2002-09-27 Akim Demaille <akim@epita.fr>
10177 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
10178 from /tmp.
10179 Thanks to Bill Moseley and Paul Eggert.
10180 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
10181 the tmpdir must be created.
10182 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp

10187 * bin/autoscan.in: Improve the comments.

10195 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
10196 Reported by Ralf Corsepius.
10197 * doc/autoconf.texi (autoreconf Invocation): Likewise.
10199 2002-09-26 Akim Demaille <akim@epita.fr>
10201 Single suffix rules and seperated dependencies are not portable.
10203 * doc/autoconf.texi (Installation Directory Variables): Update.
10204 (Limitations of Make): Some about `Single Suffix Rules and
10205 Separated Dependencies'.
10206 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10207 (ifnames, autoscan, autom4te): Un-factor into several rules.
10209 2002-09-25 Paul Eggert <eggert@twinsun.com>
10211 * BUGS (Interoperability bugs): New section. Mention libtool
10212 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
10214 2002-09-24 Paul Eggert <eggert@twinsun.com>
10216 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
10217 make handles suffix-rules differently from GNU make.
10219 * bin/Makefile.am (SUFFIXES, .in): Remove.
10220 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):

10223 2002-09-16 Akim Demaille <akim@epita.fr>
10225 i960 compilers create `b.out' files by default.
10226 Reported by Ralf Corsepius.
10228 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
10229 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
10231 2002-09-13 Paul Eggert <eggert@twinsun.com>
10233 * doc/autoconf.texi (Particular Headers): Remove obsolete
10234 reference to `struct timezone' in the description of
10235 AC_HEADER_TIME.
10237 2002-09-13 Akim Demaille <akim@epita.fr>
10239 Version 2.54.
10241 * config/config.sub, config/config.guess: Update.
10242 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
10243 * Makefile.am: Adjust.
10245 2002-09-13 Akim Demaille <akim@epita.fr>
10247 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
10248 reading config.log when the compiler is rejected.
10249 Suggested by Guido Draheim.
10251 2002-09-13 Akim Demaille <akim@epita.fr>
10253 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
10254 (chdir_init) might hang when stat'ing mounted directories.
10255 Reported by Vance Shipley.
10257 2002-09-12 Akim Demaille <akim@epita.fr>
10259 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
10260 the lists.
10262 2002-09-12 Akim Demaille <akim@epita.fr>
10264 * doc/autoconf.texi (Defining Symbols): Present two different
10265 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
10266 difference between 1 argument calls, and 2-3 argument calls.
10268 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
10270 * doc/autoconf.texi: Review grammar and punctuation.
10272 2002-09-11 Paul Eggert <eggert@twinsun.com>
10274 * doc/autoconf.texi: Fix minor formatting, spelling, and
10275 grammatical typos.
10276 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
10277 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
10278 is obsolescent.
10280 2002-09-11 Akim Demaille <akim@epita.fr>
10282 * doc/autoconf.texi (Questions): Rename as...
10283 (FAQ): this.
10284 (Defining Directories): New.
10286 2002-09-09 Akim Demaille <akim@epita.fr>
10288 * doc/autoconf.texi (Making testsuite Scripts): Update.
10289 Suggested by Nishio Futoshi.
10291 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
10293 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
10294 plain `@' is wanted.
10296 2002-09-09 Akim Demaille <akim@epita.fr>
10298 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
10299 `duplicates', since the algorithm was too naive and could keep
10300 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
10301 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
10302 Reported by Ralf Corsepius.
10303 * tests/torture.at (Configuring subdirectories): Exercise these
10304 cases.
10306 2002-09-09 Akim Demaille <akim@epita.fr>
10308 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
10309 looking for a replacement file.
10310 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
10311 directory is relative.
10312 * doc/autoconf.texi (Generic Functions): Clarify the replacement
10313 directory definition.
10314 Reported by Andreas Schwab and Jim Meyering.
10316 2002-09-06 Akim Demaille <akim@epita.fr>
10318 * doc/autoconf.texi (Setting Output Variables): Clarify what
10319 precious variables are.
10320 Suggested by Pontus Skoeld.
10322 2002-09-05 Akim Demaille <akim@epita.fr>
10324 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10325 (ifnames, autoscan, autom4te): Since we don't only depend on
10326 configure.ac variables (such as VERSION etc.), but also on prefix
10327 and so forth, depend on Makefile, not configure.ac.
10328 Reported by Alexandre Duret-Lutz.
10329 * doc/autoconf.texi (Installation Directory Variables): Adjust.
10331 2002-09-05 Kevin Ryde <user42@zip.com.au>
10333 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
10334 doesn't seem to be confined to ia64, just say "some versions".
10336 2002-09-04 Akim Demaille <akim@epita.fr>
10338 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
10339 Automake 1.6c.
10340 * Makefile.am (maintainer-clean-local): Remove.
10341 (MAINTAINERCLEANFILES): Remove COPYING.
10343 2002-09-03 Paul Eggert <eggert@twinsun.com>
10345 * doc/autoconf.texi (Configuration Commands): Remove obsolete
10346 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
10347 Brinkmann.
10349 2002-09-03 Akim Demaille <akim@epita.fr>
10351 * configure.ac: Bump to 2.53d.
10352 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
10353 as of today, on Automake's team suggestion.
10355 2002-09-03 Akim Demaille <akim@epita.fr>
10357 Version 2.53c.
10359 2002-09-02 Akim Demaille <akim@epita.fr>
10361 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
10362 SITE_MACRO_DIR.
10363 * configure.ac: Disable SITE_MACRO_DIR.
10365 2002-09-02 Jim Meyering <meyering@lucent.com>
10367 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
10368 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
10369 Also, tweak grammar: s/make sure to/be sure to/.
10371 2002-09-02 Paul Eggert <eggert@twinsun.com>
10373 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
10374 directory names are generally preferable to physical names.
10376 2002-09-02 Akim Demaille <akim@epita.fr>
10378 * lib/Autom4te/General.pm (&update_file): s/die/error/.
10379 Reported by Raja R. Harinath.
10380 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
10381 * bin/autoupdate.in: Use error instead of die.
10383 2002-09-01 Paul Eggert <eggert@twinsun.com>
10385 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
10386 ordinary shell concatenation rather than echo+tr+sed command that
10387 runs afoul of a long-line-related sed bug in Solaris 8.
10389 * bin/autoheader.in (parse_args): --warning -> --warnings.
10391 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
10392 stdout, as traditional "ls" does.
10393 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
10394 _AC_COMPILER_EXEEXT_O): Likewise.
10395 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
10397 * bin/autoconf.as: Add --prepend-include option. This patch was
10398 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
10399 but bin/autoconf.in is generated automatically from bin/autoconf.as.
10401 * bin/autoconf.in, configure: Regenerate.
10403 * doc/autoconf.texi (Special Shell Variables): Mention
10404 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
10406 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
10407 MAILPATH and set PS1, PS2, PS4 to default values, to work
10408 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
10409 For LC_ALL etc, first try to set to "C" as POSIX requires and as
10410 the Autoconf documentation specifies; fall back to "unset" only if
10411 this fails. Use a shell for-loop for this rather than an m4 loop,
10412 to shorten the output script.
10414 2002-08-30 Paul Eggert <eggert@twinsun.com>
10416 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
10417 1003.1-2001's requirements for CDPATH. Give a simpler workaround
10418 for the CDPATH problem. Document PWD.
10419 (Limitations of Builtins): Document the problem that "cd $foo" and
10420 "ls $foo" may refer to different directories in shells conforming
10421 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
10422 example, since the old example is now out of date.
10424 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
10425 FOO" and "ls FOO" talk about different directories; this catches
10426 problems when POSIX 1003.1-2001 "cd" fails due to symlink
10427 spaghetti.
10429 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
10430 of rolling our own unset.
10431 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
10432 in practice we needn't worry about CDPATH if unset doesn't work.
10434 * Makefile.in, aclocal.m4, bin/Makefile.in,
10435 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
10436 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
10437 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
10438 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
10439 tests/Makefile.in: Regenerate with Automake 1.6.3.
10441 * config/config.guess, config/config.sub, config/mkinstalldirs:
10442 Update.
10444 * configure: Regenerate with self.
10446 2002-08-30 Kevin Ryde <user42@zip.com.au>
10448 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
10449 default output.
10451 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
10453 * bin/autom4te.in (Request::load): Correctly test for "do" read
10454 failure.
10456 2002-08-29 Akim Demaille <akim@epita.fr>
10458 * lib/Autom4te/General.pm (&xqx): New.
10459 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
10460 hand, which is not portable.
10461 (&error): New.
10462 * bin/autom4te.in: Use them.
10463 Use &error instead of die.
10464 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
10465 Adjust.
10467 2002-08-17 Paul Eggert <eggert@twinsun.com>
10469 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
10470 default list of compilers to try, since it was long ago superseded
10471 by the ksh fc builtin. Suggested by Steven G. Johnson.
10473 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
10475 * doc/autoconf.texi (Invoking autom4te): End the option table,
10476 fixing a bug introduced by the previous patch.
10477 (Limitations of Make): Add a 'target lookup' subentry in the
10478 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
10480 2002-07-29 Mark D. Roth <roth@feep.net>
10482 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
10483 options and use $AUTOM4TE_PATH.
10484 * doc/autoconf.texi: Remove documentation of autom4te
10485 --include-envvar and --site-macro-subdir options and document
10486 use of $AUTOM4TE_PATH.
10487 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
10488 arguments from each language section.
10490 2002-07-29 Paul Eggert <eggert@twinsun.com>
10492 * doc/install.texi: Include copyright symbol in copyright notice.
10494 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
10495 Replace with:
10496 (AM_MAKEINFOFLAGS): New macro.
10497 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
10498 * Makefile.am (INSTALL): Use the new macros.
10499 Use -o rather than --output, since "missing" does not grok --output.
10501 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10503 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
10504 comments do not always work. Never trust the exit status of
10505 `make -k'.
10507 2002-07-24 Kevin Ryde <user42@zip.com.au>
10509 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
10510 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
10512 2002-07-23 Paul Eggert <eggert@twinsun.com>
10514 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
10515 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
10516 apparently treats PATH="nonexistent" as if it contained ".".
10517 Bug reported by Stefan `Sec' Zehl.
10519 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10521 * doc/autoconf.texi (Limitations of Make): Mention the special
10522 handling of the obj/ directory by BSD make.
10524 2002-07-20 Kevin Ryde <user42@zip.com.au>

10527 backslashes.

10532 (Programming in M4sh): Ethymology of M4sh.
10534 2002-07-19 Akim Demaille <akim@epita.fr>
10536 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
10538 2002-07-18 Akim Demaille <akim@epita.fr>
10540 Version 2.53b.
10542 2002-07-18 Akim Demaille <akim@epita.fr>
10544 * config/config.guess, config/config.sub: Update.
10546 2002-07-18 Akim Demaille <akim@epita.fr>
10548 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
10549 Automake's parts.
10551 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
10552 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
10553 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
10555 2002-07-18 Akim Demaille <akim@epita.fr>,
10556 Alexandre Duret-Lutz <duret_g@epita.fr>
10558 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
10559 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
10561 2002-07-17 Russ Allbery <rra@stanford.edu>
10563 * doc/autoconf.texi (Initializing configure): Clarify the
10564 description of the tarname default.
10566 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
10568 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
10569 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
10570 latter was not run.
10572 2002-07-17 Akim Demaille <akim@epita.fr>
10574 * lib/Autom4te/General.pm (find_file): Browse the directories in
10575 the order they are given.
10577 2002-07-17 Akim Demaille <akim@epita.fr>

10580 * tests/wrapper.as: this.
10581 * tests/Makefile.am, configure.ac: Adjust.
10583 2002-07-17 Mark D. Roth <roth@feep.net>
10585 * configure.ac: Add --enable-site-macro-dir option.

10594 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
10595 macro directory, remove note that include path directories are
10596 used in reverse order, and document --prepend-include option.
10597 * lib/autom4te.in: Use --prepend-include instead of --include.
10598 * tests/wrapsh.in: Use --prepend-include instead of --include.
10600 2002-07-17 Akim Demaille <akim@epita.fr>
10602 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): `_' is allowed in
10603 tarnames.

10643 2002-06-27 Paul Eggert <eggert@twinsun.com>
10645 * config/install-sh: Quote $src. Prefer || to test's -o option,
10646 as per "Limitations of Builtins".

10648 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
10650 * tests/mktests.sh: Use grep instead of fgrep, as per
10651 "Limitations of Builtins".
10653 2002-06-15 Paul Eggert <eggert@twinsun.com>
10655 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
10656 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
10657 so that we consistently test the just-built programs.
10658 * tests/wrappl.as: Likewise.
10660 2002-06-12 Paul Eggert <eggert@twinsun.com>
10662 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

10678 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
10680 * bin/autom4te.in ($cache): Don't define using `$me', the name
10681 of the cache should not depend on the name under which autom4te
10682 was installed.
10684 2002-06-07 Akim Demaille <akim@epita.fr>

10699 (AC_REPLACE_FNMATCH): this.
10700 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
10701 AC_FUNC_FNMATCH_GNU.
10703 2002-06-07 Akim Demaille <akim@epita.fr>
10705 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
10706 Rosetta Stone for Unix.
10708 2002-06-07 Akim Demaille <akim@epita.fr>
10710 * bin/autom4te.in (warn_forbidden): When rejecting a token,
10711 suggest m4_pattern_allow.
10712 Suggested by Adam J. Richter.
10714 2002-06-07 Akim Demaille <akim@epita.fr>
10716 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
10717 ac_config_libobj_dir.
10718 (AC_CONFIG_LIBOBJ_DIR): New.
10719 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

10726 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
10727 * tests/mktests.sh (ac_exclude_list): Don't check
10728 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
10730 2002-06-06 Paul Eggert <eggert@twinsun.com>

10777 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
10778 from the default list of compilers to try. Suggested by
10779 Kate Hedstrom.
10780 * NEWS: Document the above.
10781 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
10783 2002-05-17 Paul Eggert <eggert@twinsun.com>
10785 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
10786 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
10787 This improves on an earlier suggestion by H. Peter Anvin.
10789 2002-05-16 Paul Eggert <eggert@twinsun.com>
10791 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
10792 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
10793 Both macros now accept an optional source-dir arg.
10794 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
10796 * NEWS: Document this.
10797 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
10799 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
10800 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
10801 not for GNU extensions; this undoes part of the 2000-11-03 change,
10802 reverting to 2.13-compatible behavior.
10803 Add new optional argument DIR.
10804 (AC_FUNC_FNMATCH_GNU): New macro.
10806 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
10808 2002-05-08 Paul Eggert <eggert@twinsun.com>
10810 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
10811 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
10812 and it causes a 'test' syntax error if it fails.
10813 Bug reported by Stephen Gildea.
10815 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
10816 If prototypes are supported, use them to check this at compile-time,
10817 instead of trying to check it at run-time. If we must do a run-time
10818 check, assume that setvbuf is standard when cross-compiling, as
10819 nonstandard setvbuf occurs only on ancient and unlikely hosts.
10820 Bug reported by Paul D. Smith.
10822 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
10823 argument specifying location of getloadavg.c. This removes a
10824 FIXME. This idea was taken from Jim Meyering's implementation in
10825 textutils.
10826 * doc/autoconf.texi (Particular Functions): Document this.
10827 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
10828 that's what the code does; this fixes a bug reported by
10829 Paul D. Smith.
10831 2002-05-03 Akim Demaille <akim@epita.fr>
10833 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
10834 autopoint instead of gettextize.
10835 ($uses_alocal): Rename as...
10836 ($uses_aclocal): this.
10837 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10838 Suggested by Bruno Haible.
10840 2002-05-03 Akim Demaille <akim@epita.fr>
10842 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
10844 2002-04-29 Paul Eggert <eggert@twinsun.com>
10846 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
10847 files to be 1 second older; just set them to be the same time.
10848 Also, sleep 1 second after the first aclocal, to work around
10849 problems with sub-second time stamps on the input files.
10851 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
10853 * doc/autoconf.texi: Mention "set -e -x" lossage
10854 under node "Limitations of Builtins".
10856 2002-04-29 Akim Demaille <akim@epita.fr>
10858 * doc/install.texi: Better wording for setting variables when
10859 running configure.
10860 From Christian Cornelssen.
10862 2002-04-29 Akim Demaille <akim@epita.fr>
10864 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
10865 of lack of $LINENO support, then the test will compare the $LINENO
10866 in testsuite vs. the lineno in the test file. This is wrong, of
10867 course.
10868 Be sure to protect it.
10869 Reported by Patrick Welche.
10871 2002-04-25 Akim Demaille <akim@epita.fr>
10873 * doc/autoconf.texi (Obsolete Macros): Typo.
10874 Reported by Vladimir Volovich.
10876 2002-04-25 Akim Demaille <akim@epita.fr>
10878 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
10879 than some of the input files, hence, on the second run of aclocal,
10880 if some of its input are younger, make them older.
10881 Suggested by Paul Eggert.
10883 2002-04-25 Akim Demaille <akim@epita.fr>
10885 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
10886 Thanks to Paul Eggert.
10888 2002-04-25 Akim Demaille <akim@epita.fr>
10890 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
10891 and ac_subst_vars be sh variables containing the list of
10892 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
10893 DEFAULT diversion.
10894 (_AC_INIT_PREPARE): Use them to log them.
10895 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
10896 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
10897 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
10898 _AC_SUBST_FILES and _AC_SUBST_VARS.
10899 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
10901 2002-04-24 Akim Demaille <akim@epita.fr>
10903 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
10904 autoheader, so that automake does not complain about a missing
10905 config.h.in that was to be created.
10907 2002-04-23 Akim Demaille <akim@epita.fr>
10909 * bin/autoheader.in (parse_args): --warning takes an argument.
10910 Fixes PR/220.
10912 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
10914 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
10915 and bb.out when cleaning up.
10917 2002-04-22 Akim Demaille <akim@epita.fr>

10929 Reported by Gregory Giannoni.
10931 2002-04-22 Akim Demaille <akim@epita.fr>
10933 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
10934 Fixes false failures on Darwin.

10959 Minor spelling and grammar fixes.
10961 * doc/autoconf.texi: Follow the outline suggested in the GNU
10962 Sample Texts sections of the Texinfo 4.2 manual. Most
10963 importantly, this makes sure that the copyright notices appear in
10964 all output formats. You probably need Texinfo 4.2 to generate
10965 the manual now.
10967 Fix some bugs when using "$@" when there might be zero positional
10968 arguments in cases where this matters.

11016 Adjust Autoconf and Autotest.
11018 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
11019 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
11020 * lib/autotest/general.m4 (AT_INIT): Likewise.
11021 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

11068 (AC_CONFIG_LINKS): here.
11069 Adjust.
11070 Don't use the KILL diversion, as it kills spurious output, which
11071 results in failures being hidden.
11072 Use m4_defn where appropriate.
11073 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
11074 after the second argument.
11075 Use m4_defn.
11076 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning

11082 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
11083 expanded if $# <= 2.
11085 * bin/autoreconf.in (autoreconf): Run automake after rerunning
11086 aclocal.
11088 2002-04-03 Akim Demaille <akim@epita.fr>
11090 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
11091 (_AC_COMPILER_EXEEXT_REJECT): New.
11092 Also recognize *.bb and *.bbg as compilation byproducts.
11093 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
11094 (_AC_COMPILER_OBJEXT): Use them.
11095 Fixes Debian #138666.
11097 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
11099 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
11101 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
11102 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
11103 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
11104 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
11105 (AC_C_CONST): Same.
11106 (AC_C_INLINE): Same.
11107 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
11108 * doc/autoconf.texi, NEWS: Document.
11109 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
11110 AC_C_CROSS.
11112 2002-04-02 Akim Demaille <akim@epita.fr>
11114 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
11115 _AS_MKDIR_P_PREPARE.
11117 2002-03-28 Kevin Ryde <user42@zip.com.au>
11119 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
11120 to avoid versions of HP C which don't allow that.
11122 2002-03-27 Paul Eggert <eggert@twinsun.com>
11124 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
11125 (AS_SHELL_SANITIZE): Invoke it.
11126 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
11128 2002-03-26 Akim Demaille <akim@epita.fr>
11130 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
11132 2002-03-26 Akim Demaille <akim@epita.fr>
11134 * doc/autoconf.texi (Introduction): The GNATS base moved.
11136 2002-03-25 Paul Eggert <eggert@twinsun.com>
11138 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
11139 as POSIX requires, as it doesn't work with Zsh.
11140 * doc/autoconf.texi (Assignments): Document the problem.
11142 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11144 * doc/autoconf.texi (Limitations of Make): Mention more issue
11145 about VPATH, overriding of macros in sub-makes, and handling of
11146 SHELL.
11148 2002-03-21 Paul Eggert <eggert@twinsun.com>
11150 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
11151 problem with here-document buffer boundaries.
11153 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
11154 when reinvoking the shell, to work around problems with installers
11155 who put strange things like "cd" commands in their environments.
11157 2002-03-19 Akim Demaille <akim@epita.fr>
11159 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
11160 From Aaron Ucko.
11162 2002-03-19 Akim Demaille <akim@epita.fr>
11164 * bin/autoscan.in (scan_file): Specify the location in `&used'
11165 invocations.
11166 From Nicolas Joly.
11168 2002-03-19 Akim Demaille <akim@epita.fr>
11170 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
11171 From Nishio Futoshi.
11173 2002-03-19 Akim Demaille <akim@epita.fr>
11175 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
11177 2002-03-18 Paul Eggert <eggert@twinsun.com>
11179 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
11180 (Limitations of Usual Tools): Add mkdir section.
11182 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
11183 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
11184 back on AS_DIRNAME to compute prefixes otherwise; this is
11185 roughly what mkinstalldirs does. That way, we need not have
11186 our own filename disassembler. The old disassembler did not
11187 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
11189 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
11190 Create at_test_all by a series of assignments,
11191 not by a single assignment of a long string. The latter causes ksh
11192 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
11193 presumably because of a buffer overrun.
11195 2002-03-14 Paul Eggert <eggert@twinsun.com>
11197 * lib/autotest/general.m4 (at_times_skip):
11198 Renamed from at_times. Now a boolean.
11199 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
11200 says 'times: not found'.
11202 2002-03-14 Akim Demaille <akim@epita.fr>
11204 * bin/autoreconf.in (&study_gettextize): New.
11205 (&autoreconf): Handle newest gettextize.
11206 Rerun aclocal if needed.
11207 Suggested by Andreas Schwab.
11209 2002-03-13 Akim Demaille <akim@epita.fr>
11211 * doc/autoconf.texi (Special Shell Variables): More about IFS.
11213 2002-03-13 Akim Demaille <akim@epita.fr>
11215 * doc/autoconf.texi (Header Portability): New.
11216 Add information about stdint.h and inttypes.h from Paul Eggert.
11218 2002-03-13 Akim Demaille <akim@epita.fr>
11220 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
11221 -p'.
11222 From Bob Proulx.
11224 2002-03-12 Akim Demaille <akim@epita.fr>
11226 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
11227 m4_require.
11229 2002-03-11 Andreas Schwab <schwab@suse.de>
11231 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
11232 does not do it if --with-lispdir is given.
11234 2002-03-08 Akim Demaille <akim@epita.fr>
11236 Version 2.53.
11238 2002-03-08 Akim Demaille <akim@epita.fr>
11240 * doc/autoconf.texi (Subdirectories): Clarify that the
11241 subdirectory should exist.
11243 2002-03-08 Akim Demaille <akim@epita.fr>
11245 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
11247 2002-03-08 Akim Demaille <akim@epita.fr>
11249 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
11250 aliases the actual variables, and modifications of the former
11251 affect the latter.
11253 2002-03-08 Akim Demaille <akim@epita.fr>
11255 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
11256 because of C-c: have m4 output in tmp files, then mv them.
11258 2002-03-08 Akim Demaille <akim@epita.fr>
11260 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
11261 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
11262 * bin/ifnames.in: Copyright update.
11264 2002-03-08 Akim Demaille <akim@epita.fr>
11266 * doc/autoconf.texi (Invoking autom4te): New.
11268 2002-03-05 Akim Demaille <akim@epita.fr>
11270 * doc/autoconf.texi (Specifying Names): Clarification suggested by
11271 Kevin Ryde.
11273 2002-03-05 Akim Demaille <akim@epita.fr>
11275 Version 2.52i.
11277 2002-03-04 Akim Demaille <akim@epita.fr>
11279 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
11280 * lib/autoconf/general.m4 (AC_INIT): More informative error
11281 message for LIBOBJ.
11283 2002-03-04 Akim Demaille <akim@epita.fr>
11285 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
11286 parallel builds.
11288 2002-03-04 Akim Demaille <akim@epita.fr>
11290 * doc/autoconf.texi (Transforming Names): Equality between target
11291 and host is irrelevant.
11292 (Specifying Names, Canonicalizing): Remove all references to the
11293 backward compatibility hooks. Rather, collect them all into...
11294 (Hosts and Cross-Compilation): this new section.
11295 * doc/install.texi (System Type): Ditto.
11296 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
11297 that `--host' implies cross-compilation.
11299 2002-03-04 Akim Demaille <akim@epita.fr>
11301 * doc/autoconf.texi (Evaluation Macros): New.
11302 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
11303 useless.
11304 (_m4_foreach): Define the variant with immediate evaluation so
11305 that it contains exactly the items, not an expression which
11306 evaluation is the current item.
11307 (m4_re_string, m4_re_word): Don't over quote them.
11309 2002-03-04 Akim Demaille <akim@epita.fr>
11311 Instead of having stacking `shift's evaluated at the end, let
11312 `foreach' loops immediately evaluate them.
11314 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
11315 $*. This is the n-th time I change my mind, but hopefully this is
11316 the last...
11317 (m4_lquote): New.
11318 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
11319 efficient.
11320 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
11321 it was only a hack for m4_text_wrap.
11322 (m4_car2): Remove, replaced by...
11323 (m4_cdr): New.
11324 (_m4_foreach): Adjust.
11325 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
11326 m4_bpatsubst for clarification.
11328 2002-03-04 Akim Demaille <akim@epita.fr>
11330 * doc/autoconf.texi (Changequote is Evil): New.
11332 2002-03-03 Kevin Ryde <user42@zip.com.au>
11334 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
11335 on old systems like SunOS.
11337 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
11339 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,

11343 of messages.
11345 2002-02-28 Akim Demaille <akim@epita.fr>
11347 * lib/autotest/general.m4 (AT_INIT): Suggest a title to the
11348 message to be sent.

11357 From Akinori Musha.
11359 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
11361 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
11362 translate \r\n to \n.
11364 2002-02-07 Akim Demaille <akim@epita.fr>
11366 Version 2.52h.
11368 2002-02-07 Akim Demaille <akim@epita.fr>
11370 Fix Autoconf PR/209.
11371 Also reported by Frank Denis.
11373 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
11375 2002-02-07 Akim Demaille <akim@epita.fr>
11377 Fix Autoconf PR/207:
11378 AC_PREFIX_PROGRAM fails with dashed program names
11380 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
11381 variable when looking for the prefix program.
11382 Now it also works for shell variables.
11384 2002-02-07 Akim Demaille <akim@epita.fr>
11386 * doc/autoconf.texi (Limitations of Builtins): More about
11387 case/esac.
11389 2002-02-06 Akim Demaille <akim@epita.fr>
11391 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
11392 case/esac, some shells don't support it.
11393 Reported by Zack Weinberg.
11394 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
11396 2002-02-06 Akim Demaille <akim@epita.fr>
11398 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
11399 sure not to introduce newlines in at_groups.
11400 * lib/autotest/Makefile.am (autotest.m4f): Typo.
11402 2002-02-06 Akim Demaille <akim@epita.fr>
11404 * tests/torture.at (Configuring subdirectories): Skip if aclocal
11405 is not available.
11407 2002-02-05 Paul Eggert <eggert@twinsun.com>
11409 * doc/autoconf.texi (Specific Compiler Characteristics):
11410 Describe HP-UX cc bug workaround more accurately.
11411 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
11412 not unsigned long.
11413 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
11414 cross-compilers, too. This undoes some of the most recent change
11415 to this file.
11417 2002-02-05 Akim Demaille <akim@epita.fr>
11419 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
11420 to make sure they are up to date when `check' is run.
11422 2002-02-05 Akim Demaille <akim@epita.fr>
11424 * doc/autoconf.texi (Making testsuite Scripts): Document

11429 * lib/freeze.mk: New.
11431 2002-02-05 Akim Demaille <akim@epita.fr>
11433 Implement `autom4te --freeze'.
11435 * bin/autom4te.in (&freeze): New.
11436 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
11437 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
11439 2002-02-05 Akim Demaille <akim@epita.fr>
11441 * bin/autom4te.in (&parse_args): Implement `frozen files are
11442 optional are the sum of the previous files on the command line'.
11443 Also, pass `--reload-state=' on them, so...
11444 (handle_m4): don't.
11445 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
11446 (M4sh): Rely on M4sugar.
11447 (Autotest, M4sh, M4sugar): Use frozen files.
11449 2002-01-31 Akim Demaille <akim@epita.fr>
11451 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
11452 * doc/autoconf.texi (Initializing configure): Adjust.
11454 2002-01-30 Akim Demaille <akim@epita.fr>
11456 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
11457 alphanumeric to `-' instead of `_'.
11459 2002-01-30 Akim Demaille <akim@epita.fr>
11461 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
11462 for plain code, the other for cross-compilation code. The latter
11463 is now run with GCC only.
11464 * doc/autoconf.texi (Compilers and Preprocessors): New.
11466 2002-01-30 Akim Demaille <akim@epita.fr>
11468 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
11469 values.
11470 * doc/autoconf.texi (Initializing configure): Explain how to
11471 change AC_INIT default values.
11473 2002-01-29 Akim Demaille <akim@epita.fr>
11475 * tests/torture.at (Configuring subdirectories): Use configure.in,
11476 so that aclocal 1.4 works.
11477 Reported by Alexandre Duret-Lutz and Larry Schmitt.
11479 2002-01-28 Akim Demaille <akim@epita.fr>
11481 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
11482 needs an argument.
11484 2002-01-28 Akim Demaille <akim@epita.fr>
11486 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
11487 AUTOTEST_PATH *after* it was set.
11488 Don't put `.' in the PATH: the user should be precise and `./' if
11489 needed. In addition, given that the test suite does some `cd', if
11490 `.' is in the path, the `tested programs' sections will report
11491 programs found in the test suite's directory, while during the
11492 tests (performed in their own directory), these programs are no
11493 longer visible. In other words, the results is confusing and
11494 useless.
11495 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
11497 2002-01-24 Akim Demaille <akim@epita.fr>

11508 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
11509 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
11510 Bourne. Use /bin/sh.
11511 From Andreas Buening.
11513 2002-01-24 Akim Demaille <akim@epita.fr>

11525 Automake.
11527 2002-01-24 Akim Demaille <akim@epita.fr>
11529 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
11530 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.

11533 2002-01-21 Akim Demaille <akim@epita.fr>
11535 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
11537 2002-01-21 Akim Demaille <akim@epita.fr>
11539 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
11540 message on invalid options.
11541 * bin/autom4te.in (parse_args): Don't use
11542 Autoconf::General::getopt with non valid options.
11544 2002-01-17 Jim Meyering <meyering@lucent.com>
11546 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
11547 $ac_cv_exeext so we don't use an old, invalid, cached value.
11549 2002-01-11 Akim Demaille <akim@epita.fr>
11551 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
11552 Meyering.
11553 * doc/autoconf.texi (Function Portability): Document the strnlen
11554 limitation.
11555 (Particular Functions): Document AC_FUNC_STRNLEN.
11556 * lib/autoscan/functions: Adjust.
11558 2002-01-06 Akim Demaille <akim@epita.fr>
11560 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
11561 package.m4, since is really depends upon configure.ac, not
11562 configure.
11563 * doc/autoconf.texi (testsuite Scripts): Adjust.
11564 * tests/Makefile.am (package.m4): New.
11565 EXTRA_DIST it since its a source.

11569 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
11570 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
11571 and PACKAGE_BUGREPORT from here...
11572 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
11573 arguments.
11574 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
11575 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
11576 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
11577 * tests/tools.at (autoheader): Adjust.
11578 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
11580 2002-01-06 Akim Demaille <akim@epita.fr>
11582 * bin/autoscan.in (scan_file): Use `&used'.
11584 2002-01-03 Akim Demaille <akim@epita.fr>
11586 * doc/autoconf.texi (Output): Improved wording regarding use of
11587 AC_OUTPUT.
11588 From Olly Betts.
11590 2001-12-18 Kevin Ryde <user42@zip.com.au>
11592 * doc/autoconf.texi (Function Portability): Add notes on sscanf
11593 sometimes needing writable input.
11595 2001-12-17 Jim Meyering <meyering@lucent.com>
11597 * doc/autoconf.texi (New Macros): Tweak wording.
11599 2001-12-14 Akim Demaille <akim@epita.fr>
11601 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
11602 trailing files, don't apply `-rf' to files which might not be
11603 created by configure (core, core.*, and *.core), but just `rm -f'.
11604 Suggested by Jonathan Kamens.
11606 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
11608 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
11610 2001-12-14 Akim Demaille <akim@epita.fr>
11612 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
11614 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
11616 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
11617 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
11618 abs_srcdir, top_srcpath to abs_top_srcdir.
11619 (_AC_OUTPUT_FILES): Adjust.
11620 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
11621 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
11622 * tests/wrappl.in, tests/wrapsh.in: Adjust.
11624 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
11626 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
11627 C/Fortran linking on HP/UX, by extracting the Fortran library
11628 search path from the LPATH line in the $F77 -v output.
11630 2001-12-12 Kevin Ryde <user42@zip.com.au>
11632 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
11633 forbidden file descriptors table.
11635 2001-11-26 Akim Demaille <akim@epita.fr>
11637 * bin/autoscan.in (%c_keywords): Build it at top level.
11638 Map to 1 in order to simplify its uses.
11640 2001-11-26 Akim Demaille <akim@epita.fr>
11642 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
11643 Remove $filepath, useless.
11644 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
11645 variables, they are really part of the tokens.
11646 Split the input line on spaces and then look for tokens.
11647 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
11648 because of `lex$U.$(OBJEXT)'.
11649 (&scan_files): Use "@list" instead of join.
11650 * doc/Makefile.am (CLEANFILES): Add *.fns.
11652 2001-11-26 Akim Demaille <akim@epita.fr>
11654 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
11655 Remove, replaced by...
11656 * tests/wrappl.in: Be common for all the Perl executables.
11657 In particular autoscan and autoheader want -I.
11658 * configure.ac: Adjust.
11659 * lib/autoscan/headers: errno.h is portable.
11661 2001-11-26 Akim Demaille <akim@epita.fr>
11663 * bin/autoscan.in (used): New.
11664 Use it.
11666 2001-11-26 Akim Demaille <akim@epita.fr>
11668 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
11669 directives.
11670 (&scan_sh_file): Remove a duplicate pattern.
11671 (&check_configure_ac): Use long options.
11672 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
11674 2001-11-26 Akim Demaille <akim@epita.fr>
11676 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
11677 Before, having a line containing the opening of a multi line
11678 comment made the whole line be ignored.
11680 2001-11-26 Akim Demaille <akim@epita.fr>
11682 * doc/autoconf.texi (Using an Autotest Test Suite): New.
11683 (testsuite Scripts): Be one of its subsection.
11684 (Autotest Logs): New.
11686 2001-11-26 Akim Demaille <akim@epita.fr>
11688 Test groups are now run two directories deeper.
11690 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
11691 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
11692 at_top_builddir.
11693 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
11694 top_srcdir, builddir and top_builddir.
11695 Use `at_*dir' relatively to the directory containing the
11696 suite, use `*dir' when relatively to the current group dir.
11698 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
11700 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
11701 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
11702 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
11703 spelling errors.
11705 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11707 * doc/autoconf.texi (Using System Type): Add an example of `case
11708 $host' usage so people quit using `case $target' everywhere.
11710 2001-11-22 Akim Demaille <akim@epita.fr>
11712 * doc/autoconf.texi (Installation Directory Variables): Englishoes
11713 spotted by Jim Meyering.
11715 2001-11-16 Paul Eggert <eggert@twinsun.com>
11717 This patch implements a `long double' suggestion by Oliver Kiddle.
11719 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
11720 static, to catch errors if the value isn't known at compile-time
11721 and the compiler supports dynamic arrays. Change its name from
11722 `_array_' to `test_array' to avoid potential name clashes.
11723 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
11724 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
11725 better than double. Catch a bug in GCC 2.95.2 x86.
11726 * doc/autoconf.texi (C Compiler): Document the above.
11727 * NEWS: Likewise.
11729 2001-11-13 Akim Demaille <akim@epita.fr>
11731 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
11732 hand.
11733 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
11735 2001-11-13 Akim Demaille <akim@epita.fr>
11737 * lib/autotest/general.m4 (AT_INIT): After having run the test
11738 group, go back to the initial directory, not to at_suite_dir.
11740 2001-11-13 Akim Demaille <akim@epita.fr>
11742 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
11743 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
11744 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
11745 option.
11746 (AT_CHECK_CONFIGURE): Use absolute paths.
11747 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
11748 The problem is still the old one: there is no means in M4 (that I
11749 know about) to create a defining macro, because there is no means
11750 to create `$1' etc., therefore, the defining macro ``swallows''
11751 all the arguments meant to the defined macro.
11753 2001-11-13 Akim Demaille <akim@epita.fr>
11755 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
11756 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
11757 configure.ac.
11758 * tests/aclocal.m4: Remove, as it is no longer used.
11760 2001-11-13 Akim Demaille <akim@epita.fr>
11762 * lib/autotest/general.m4: Change `tests?' into `groups?' in
11763 variable names when referring to a single test group, or to
11764 `suite' when referring to the whole test suite.
11765 `at_last_test' is removed: m4 compute at_format itself.
11766 (at_stdout, at_stder1, at_stderr): New variables.
11767 (AT_CHECK): Use them.
11769 2001-11-13 Akim Demaille <akim@epita.fr>
11771 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
11772 in PATH.
11773 Create `testsuite.dir/003/run' instead of `testsuite.003'.
11774 Do it as soon as a test fails, don't wait till the end of the test
11775 suite.
11776 Don't remove $as_me.[0-9]*, since these files no longer exist.
11778 2001-11-13 Akim Demaille <akim@epita.fr>
11780 * tests/tools.at: Use absolute paths, since we are no longer run
11781 in place.
11783 2001-11-13 Akim Demaille <akim@epita.fr>
11785 Now that tests are running in their own private dir, there is no
11786 need to list the files to remove at the end of tests groups.
11788 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
11789 (AT_data_files, at_data_files): Remove.
11790 (AT_CLEANUP, AT_DATA): Simplify.
11791 (AT_INIT): Adjust.
11792 Remove the group dir if !debug && !failed.
11793 * tests/atspecific.m4: Adjust.
11795 2001-11-13 Akim Demaille <akim@epita.fr>
11797 Start a new layout for Autotest: `testsuite' creates
11798 `testsuite.dir' in which the at-check-line etc. files are to be
11799 found, and `testsuite.dir/003' where the test group 3 is run.
11801 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
11802 at_check_line_file, at_format, at_test_normalized, at_group_dir
11803 are new variables.
11804 Create the directories.
11805 Use absolute paths for at- files.
11806 (AT_CHECK): Adjust.
11808 2001-11-11 Michael Matz <matz@kde.org>
11810 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
11811 (m4_car2): New.
11812 (m4_car): Properly quote arguments.
11814 2001-11-13 Akim Demaille <akim@epita.fr>
11816 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
11817 with stricter rules on LIBOBJS.
11819 2001-11-12 Paul Eggert <eggert@twinsun.com>
11821 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
11822 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
11823 __PROTOTYPES too.
11825 2001-11-12 Akim Demaille <akim@epita.fr>
11827 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
11829 2001-11-12 Akim Demaille <akim@epita.fr>
11831 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
11832 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
11833 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11834 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
11835 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
11836 specify to what the macro should be defined (typically to 1).
11838 2001-11-12 Akim Demaille <akim@epita.fr>
11840 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
11841 From Jim Meyering.
11843 2001-11-12 Akim Demaille <akim@epita.fr>
11845 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11846 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
11847 definition used by Automake where LEX is +/- "${missing} lex" and
11848 `missing' itself contains variables.
11850 2001-11-12 Akim Demaille <akim@epita.fr>
11852 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
11853 Now that M4sh pushes BODY, the comments were output at the end of
11854 the test suites.
11856 2001-11-08 Akim Demaille <akim@epita.fr>
11858 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
11859 that we can trace macros from aclocal.m4.
11860 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
11861 obsoleted, and redirect to the former anyway.
11862 Reported by Ralf Corsepius.
11864 2001-11-08 Akim Demaille <akim@epita.fr>
11866 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
11867 processed only if present.
11868 * tests/torture.at (Configuring subdirectories): Use autoreconf
11869 instead of successive calls to autoconf.
11870 Add a nonexistent subdirectory to exercise the patch above.
11871 Reported by Ralf Corsepius.
11873 2001-11-08 Kevin Ryde <user42@zip.com.au>
11875 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
11876 doesn't accept .S files.
11878 2001-11-07 Akim Demaille <akim@epita.fr>
11880 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
11881 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
11882 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
11883 * bin/autom4te.in (warn_forbidden): New.
11884 (handle_output): Use it.
11885 Read m4_pattern_forbid with messages.
11887 2001-11-05 Akim Demaille <akim@epita.fr>
11889 * bin/autom4te.in (--normalize): Remove.
11890 * lib/autom4te.in: Adjust.
11892 2001-11-05 Akim Demaille <akim@epita.fr>
11894 * tests/Makefile.am (testsuite): Rename this target as...
11895 ($(TESTSUITE)): this.
11896 From Nicolas Joly.
11898 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
11900 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
11901 the --prefix option, also remove it's argument.
11903 2001-11-05 Akim Demaille <akim@epita.fr>
11905 * doc/autoconf.texi (testsuite Invocation): Update.
11906 (Writing testsuite.at): Update.
11908 2001-11-03 Akim Demaille <akim@epita.fr>
11910 * doc/autoconf.texi: s/@code/@command/ where appropriate.
11912 2001-11-03 Akim Demaille <akim@epita.fr>
11914 * lib/Autom4te/General.pm: (&catfile, &canonfile)
11915 (&file_name_is_absolute): New, wrappers around routines from
11916 File::Spec.
11917 Use and export them.
11918 (&find_configure_ac): Optionally take a directory where to look at.
11919 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
11920 the arguments.
11921 Default @ARGV to `.', not find_configure_ac.
11922 (&autoreconf): Argument is a directory.
11923 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
11924 * doc/autoconf.texi (autoreconf Invocation): Update.
11926 2001-11-03 Akim Demaille <akim@epita.fr>
11928 * lib/Autom4te/General.pm (@export_vars, @export_subs)
11929 (@export_forward_subs): New.
11930 Add basename, dirname, and fileparse.
11931 (@EXPORT): Adjust.
11932 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
11933 Don't look for aclocal flags if we already know aclocal is not
11934 used.
11935 Move aclocal.m4t only if it exists.
11936 Reported by Ezra Peisach.
11938 2001-11-03 Akim Demaille <akim@epita.fr>
11940 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
11941 passed on command line, defaulting to ./configure.ac if present.
11942 (&maybe_autoreconf, File::Find): Remove, unused.
11943 (&autoreconf): If autoconf is not used, don't try to trace.
11945 2001-11-02 Akim Demaille <akim@epita.fr>
11947 * configure.ac: Bump to 2.52g.
11949 2001-11-02 Akim Demaille <akim@epita.fr>
11951 Version 2.52f.
11953 2001-11-02 Akim Demaille <akim@epita.fr>
11955 * config/config.guess, config/config.sub, doc/standards.texi:
11956 * config/lispdir.m4: Update from masters.
11957 * configure.ac: Bump to 2.52f.
11959 2001-11-02 Akim Demaille <akim@epita.fr>
11961 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
11962 Don't run aclocal when aclocal.m4 is not from aclocal.
11963 From Ezra Peisach.
11964 Don't run libtoolize and gettextize if --install is not given.
11966 2001-11-01 Paul Eggert <eggert@twinsun.com>
11968 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
11969 be invoked before _AS_LINENO_PREPARE.
11970 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
11971 than character ranges.
11973 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
11974 invoking AS_BASENAME. Set the locale variables to 'C' if
11975 possible, as POSIX requires this to get the traditional
11976 behavior.
11977 * doc/autoconf.texi (Special Shell Variables): Describe the above.
11979 2001-10-31 Paul Eggert <eggert@twinsun.com>
11981 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
11982 with {}, as that triggers a bug in Bash 2.05.
11984 (_AS_LINENO_PREPARE): Use Sed rather than
11985 Awk. Fix the sed prepass to work even if there are multiple
11986 instances of $LINENO on the same line. Do not substitute for
11987 other variables like $LINENOT. Do not check file dates; such a
11988 check is unreliable on sufficiently fast machines, and removing
11989 the check makes the code simpler and more reliable. Check for
11990 output and chmod failures.
11992 * doc/autoconf.texi (Special Shell Variables): Document
11993 the above.
11995 2001-10-31 Akim Demaille <akim@epita.fr>
11997 * tests/Makefile.am (atconfig): Remove this target, Automake
11998 handles it now.
12000 2001-10-31 Akim Demaille <akim@epita.fr>
12002 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
12003 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
12004 provided, while it is optional.
12005 * configure.ac: Adjust.
12007 2001-10-26 Paul Eggert <eggert@twinsun.com>
12009 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
12010 lib/Autom4te/Struct.pm:
12011 Require Perl 5.005_03 instead of just 5.005, as some tests fail
12012 with 5.005_02.
12014 * doc/autoconf.texi (Special Shell Variables): Document some
12015 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
12017 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
12018 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
12019 eval $LINENO is not portable in practice.
12021 2001-10-24 Akim Demaille <akim@epita.fr>
12023 * lib/Autom4te/General.pm (backname): New.
12025 2001-10-24 Akim Demaille <akim@epita.fr>
12027 * m4/: Remove, merged into...
12028 * config/: here.
12030 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
12032 * doc/autoconf.texi (Shellology): Mention the problems with bash
12033 2.05's use of ANSI quoting in its `set' builtin.

12037 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
12038 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
12039 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
12040 POSIX decided to standardize on the int flavor of strerror_r.
12041 Always do char* test, as there's no reason not to.
12042 Assign to a char* var, to catch strerror_r that returns int*.
12044 * doc/autoconf.texi (Particular Functions):
12045 Document the above changes. Also, document the fact that
12046 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.

12111 (AS_BASENAME_SED): Do not assume GNU sed semantics.
12112 (AS_BASENAME): Use 'basename' if that works; then try 'expr';

12116 contains white space.
12117 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

12485 2001-09-23 Alexandre Duret-Lutz <duret_g@epita.fr>
12487 * doc/autoconf.texi (Special Shell Variables): Add pdksh output
12488 for $LINENO.
12490 2001-09-22 Akim Demaille <akim@epita.fr>
12492 * lib/autoconf/autotest.m4: Create `package.m4'.
12493 * tests/Makefile.am (package.m4): Remove.
12495 2001-09-22 Akim Demaille <akim@epita.fr>
12497 Rely on `$LINENO' when possible instead of `__oline__'.
12499 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
12500 `$LINENO' support replacement when not supported.
12501 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
12502 them explicitly to be sure they are not output before this section
12503 (via m4_require). Cosmetic only.
12504 * lib/autoconf/c.m4, lib/autoconf/general.m4,
12505 * lib/autoconf/programs.m4: Replace all the occurrences of
12506 `__oline__' with `$LINENO'.
12507 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
12509 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
12511 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
12512 character (u: -> ue) in a code comment.
12513 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
12514 it works.
12516 2001-09-21 Akim Demaille <akim@epita.fr>
12518 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
12519 Suggested by Jim Meyering.
12521 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12523 * lib/autoconf/programs.m4: Use extensions listed in
12524 $ac_executable_extensions when looking for programs.
12526 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12528 * lib/autoconf/general.m4: Fix a small Englisho.
12529 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
12530 setting up ac_dir_suffix and ac_top_builddir.
12531 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
12533 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12535 * doc/autoconf.texi (File System Conventions): Clarify the use of
12536 PATH_SEPARATOR.
12537 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
12538 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
12539 be used instead of ':'.
12540 * lib/autotest/general.m4: Replace occurrences of ':' in
12541 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
12543 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12545 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
12546 arguments. Fixed a typo.
12548 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12550 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
12551 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
12553 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12555 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
12556 * bin/autoupdate.in: Ditto.
12557 * bin/autoheader.in: Reworded a few comments.
12558 * bin/autoconf.in: Reworded help text for a few options.
12559 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
12560 * bin/autoscan.in, bin/autoupdate.in: Ditto.
12562 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12564 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
12565 already have $file). Set output files to binary mode (helps avoid
12566 CR issues on DOSish systems).
12568 2001-09-19 Akim Demaille <akim@epita.fr>
12570 * lib/autotest/general.m4: Englishoes.
12571 From Tim Van Holder and Alexey Mahotkin.
12573 2001-09-18 Paul Eggert <eggert@twinsun.com>
12575 * doc/autoconf.texi (Common Shell Constructs): New node,
12576 documenting AS_DIRNAME.
12577 (Limitations of Usual Tools): Refer to it when discussing dirname.
12578 Also, update discussion of POSIX standard to reflect latest draft.
12580 * lib/autoconf/c.m4:
12581 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
12583 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
12584 Do not pass a first argument with leading '-'
12585 to expr, by parenthesizing initial integers that might be negative.
12587 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
12588 now merely checks whether it is an error to pass an argument
12589 to getpgrp.
12591 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
12592 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
12593 whether it is a (compile-time) error to pass an argument to
12594 getpgrp. This simpler test supports the revised documentation,
12595 and is all that AC_FUNC_GETPGRP's users really need.
12597 2001-09-18 Akim Demaille <akim@epita.fr>
12599 * doc/autoconf.texi (Limitations of Make) <$<>: New.
12601 2001-09-18 Akim Demaille <akim@epita.fr>
12603 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
12604 `{}'.
12605 * lib/autotest/general.m4 (AT_INIT): Adjust.
12607 2001-09-18 Paul Wagland <paul@wagland.net>
12609 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
12610 correctly.
12611 Add test for AS_BASENAME.
12612 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
12613 added test. It now correctly handles /1/2/3/, returning '3' not ''.
12614 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
12615 * tests/base.at: Fixed the expected responses. The old ones were
12616 one line out...
12617 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
12618 the documentation claims it should (and how it behaved in 2.13).
12620 2001-09-18 Akim Demaille <akim@epita.fr>
12622 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
12623 the AC_CONFIG_COMMANDS invocation.
12624 This also solves the name clash problems.
12625 Don't set the package's ID.
12626 * lib/m4sugar/Makefile.am (version.m4): Revamp.
12627 No longer to be shipped.
12628 (version.in): Remove.
12629 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
12630 * lib/autoconf/status.m4: Adjust.
12631 Use `m4_PACKAGE_STRING'.
12632 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
12633 the only optional argument is the name of the test suite.
12634 Expect `package.m4' to define the package signature.
12635 * lib/autom4te.in (Autotest): Add `package.m4?'.
12636 * tests/Makefile.am (package.m4): New.
12637 * tests/suite.at: ifnames is a victim.
12639 2001-09-18 Akim Demaille <akim@epita.fr>
12641 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
12642 AC_LIBSOURCE, AC_CONFIG_FILES.
12643 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
12644 program version string doesn't match the package's.
12645 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
12646 after `(cached)'.
12648 2001-09-17 Paul Eggert <eggert@twinsun.com>
12650 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12651 Allow expression to return any value that can fit into unsigned long
12652 (not int, as before). Check for output errors.
12654 2001-09-17 Bruno Haible <haible@ilog.fr>
12656 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12657 Always include <stdio.h> and <stdlib.h>. Evaluate
12658 the expression in an extra function before these includes. Call
12659 fprintf "%d" only after ensuring the argument is of type 'int'.
12660 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
12662 2001-09-17 Paul Eggert <eggert@twinsun.com>
12664 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
12665 or CFLAGS=-O5. In that case, the linker has a relaxed view of
12666 fatal errors, and AC_CHECK_LIB causes it to include libraries even
12667 when they don't exist.
12669 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
12670 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
12671 need it.
12673 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
12674 version with the version used by fileutils 4.1, except use
12675 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
12676 we don't need it.
12678 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
12680 2001-09-13 Akim Demaille <akim@epita.fr>
12682 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
12683 _first_.
12684 Reported by Gerrit P. Haase.
12686 2001-09-13 Akim Demaille <akim@epita.fr>
12688 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
12689 m4_defn'ing is valid.

12695 Use it.

12703 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
12704 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
12705 Likewise.
12706 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
12707 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
12708 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
12709 AT_tests_all for consistency.
12710 Set at_victims.
12711 (AT_VICTIMS): Similar to AT_KEYWORDS.
12712 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
12714 2001-09-13 Akim Demaille <akim@epita.fr>
12716 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
12718 2001-09-13 Akim Demaille <akim@epita.fr>
12720 * lib/autotest/general.m4 (AT_INIT): Create and remove
12721 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
12722 test suites can cohabit.
12724 2001-09-13 Akim Demaille <akim@epita.fr>
12726 * tests/mktests.sh: Don't output banners for empty test files.
12728 2001-09-13 Akim Demaille <akim@epita.fr>
12730 Test suites can be run independently of configure.
12732 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
12733 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.
12734 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust: AC_SUBST

12765 (AT_CLEANUP_FILE_IFELSE, AT_CLEANUP_FILE): Rename as...
12766 (_AT_CLEANUP_FILE_IF, _AT_CLEANUP_FILE): these.
12767 (_AT_CLEANUP_FILE_IF): Simplify the regexp.
12768 (AT_SETUP): Reset AT_line, AT_keywords, AT_description.
12769 No longer fill the HELP diversion.
12770 (AT_CLEANUP): Use them.
12771 * lib/m4sugar/m4sugar.m4 (m4_append): Support a separator.
12772 (m4_list_append): Remove.
12774 Spread a few keywords in the Autoconf test suite.
12776 2001-09-10 Akim Demaille <akim@epita.fr>
12778 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

12794 2001-09-07 Akim Demaille <akim@epita.fr>
12796 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
12797 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
12798 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
12799 related variables into `at_package_*'.

12809 Move toward possibly stand-alone test suites.
12811 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
12812 in addition, it introduces useless differences in logs.
12813 (AT_INIT): Let atconfig and atlocal be both optional.
12814 Adjust PATH computation.
12815 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

12825 to avoid GCC warnings.
12826 From Uwe Seimet.
12828 2001-09-05 Akim Demaille <akim@epita.fr>
12830 * bin/autom4te.in: --language is -l, not -s.
12832 2001-09-05 Akim Demaille <akim@epita.fr>
12834 Be ready to handle filenames as stupid as `dnl.at', for if even
12835 the maintainer is dumb enough to do that...
12837 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
12838 excellence in M4 quotation: consider `__file__' is active.
12840 And BTW, when invoking m4, pass the --include in the right order:
12841 the wrong one.
12843 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
12844 4m.

12866 2001-09-05 Akim Demaille <akim@epita.fr>
12868 CVS GNU M4 doesn't like `undefine(undefined)'.
12870 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
12871 New, extracted from main.
12872 Use IO::File wherever possible.
12873 (input.m4): Be constant, use -I instead of hard coding $tmp.
12874 Therefore be a quoted heredoc.
12875 Don't invoke `_au_disable', since ac was not loaded, but just
12876 `unm4.m4'.
12878 2001-08-31 Akim Demaille <akim@epita.fr>
12880 Version 2.52d.

12890 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
12891 serious problems handling heredocs in heredocs.
12892 Reported by Nicolas Joly.
12894 2001-08-31 Akim Demaille <akim@epita.fr>
12896 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
12897 (Making testsuite Scripts): Update.
12899 2001-08-31 Akim Demaille <akim@epita.fr>
12901 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
12903 2001-08-31 Akim Demaille <akim@epita.fr>
12905 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
12906 (testsuite Scripts): There is no such thing as `atconfig.in'.
12907 And actually one diagram is missing: test suite runtime.
12909 2001-08-31 Akim Demaille <akim@epita.fr>
12911 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
12912 inverse order.
12914 2001-08-31 Akim Demaille <akim@epita.fr>
12916 * bin/autoupdate.in (@include): `installcheck' revealed the path
12917 to m4sugar was lacking!
12919 2001-08-31 Akim Demaille <akim@epita.fr>
12921 * man/Makefile.am (.x.1): We really have to pass
12922 autom4te_perllibdir.
12924 2001-08-31 Akim Demaille <akim@epita.fr>
12926 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
12927 debug scripts, in particular passing explicitly listed tests to
12928 run is stupid.
12930 2001-08-31 Akim Demaille <akim@epita.fr>
12932 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
12933 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
12934 Use directly autom4te, not autoconf.
12935 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
12937 2001-08-31 Akim Demaille <akim@epita.fr>
12939 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
12940 * bin/autoheader.in (%symbol): Strip arguments of macros.

12944 * doc/autoconf.texi: Catch up -I, --include changes.
12946 2001-08-31 Akim Demaille <akim@epita.fr>
12948 * bin/autom4te.in (&parse_args): Die on unknown languages.
12949 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
12950 need for autoconf.
12951 Promote --include over --macrodir and other obsolete options.
12953 2001-08-31 Akim Demaille <akim@epita.fr>
12955 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
12956 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
12957 * bin/autom4te.in ($autoconf): Pass --force.
12958 `print $out' doesn't print `$_' but `$out'.
12959 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
12960 (autoheader): Pass --force since the test suite goes too fast for
12961 the time stamps.
12962 Adjust to the new autoheader messages.
12964 2001-08-31 Akim Demaille <akim@epita.fr>
12966 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
12967 Check the completeness of the #template.
12968 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
12969 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
12970 invocation.
12972 2001-08-31 Akim Demaille <akim@epita.fr>
12974 * lib/Autom4te/General.pm (&find_file, &update_file): New.
12975 * bin/autoupdate.in, bin/autoheader.in: Adjust.
12976 Drop AC_MACRODIR dead for real.
12977 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
12978 `autoheader: `config.hin' is created'.
12979 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
12981 2001-08-31 Akim Demaille <akim@epita.fr>
12983 * bin/autoheader.in: Rewrite in Perl.
12984 * tests/autoheader: Adjust.
12986 2001-08-31 Akim Demaille <akim@epita.fr>
12988 * bin/autoconf.in (--include, -I): New option.
12989 Map --localdir, --autoconf-dir onto it.
12990 Forward autom4te's options instead of interpreting them.
12991 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
12992 There is no such envvar since the inception of autom4te.cfg.
12993 * bin/autom4te.in (&parse_args): Uniquify `@include'.
12994 * bin/autoupdate.in: Adjust, and perform more control.
12995 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
12996 * tests/autoconf: Dittowise.
12998 2001-08-31 Akim Demaille <akim@epita.fr>
13000 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
13001 * bin/autom4te.in (&find_file): Support `FILE?' standing for
13002 optionally `FILE'.
13003 Use -e, not -f, since /dev/null for instance is OK.
13004 (&parse_args): Adjust.
13005 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
13007 2001-08-31 Akim Demaille <akim@epita.fr>
13009 * configure.ac: Also find tested executables in bin.
13010 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
13011 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
13012 installed peer executables, only PATH is allowed to resolve it.
13013 Pass `autoconf_dir' via options, not via invisible envvars.
13014 * lib/Autom4te/General.pm (&find_peer): Remove.
13015 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
13016 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
13017 * man/Makefile.am: Let help2man rely on PATH instead of trying to
13018 find the executables for it.
13019 * tests/Makefile.am: Major cleanup. Too lazy to document...
13020 * tests/atlocal.in: Remove all the obscure envvar manipulations.
13021 We only need PERL.
13022 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
13023 indeed related to running the test suite, while passing
13024 --autoconf-dir and others is related to running non installed
13025 Autoconf executables. So don't do that, leave it to...
13026 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
13027 * tests/autoscan: New.
13028 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
13029 refer to library files: rely on --language.
13031 2001-08-29 Akim Demaille <akim@epita.fr>
13033 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
13034 s/--set/--language/.
13036 2001-08-29 Akim Demaille <akim@epita.fr>
13038 * doc/autoconf.texi: Strip the @nodes.
13039 Suggested by Paul Eggert.

13042 2001-08-29 Akim Demaille <akim@epita.fr>
13044 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
13045 Suggested by Paul Eggert.
13047 2001-08-29 Akim Demaille <akim@epita.fr>
13049 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
13050 download in a tmp dir.
13052 2001-08-29 Akim Demaille <akim@epita.fr>
13054 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
13055 case insensitive OSes out there :(

13065 (&parse_args): Support --mode, --set, and --melt.
13066 * bin/autoconf.in: Simplify and adjust.
13067 * tests/Makefile.am (AUTOMAKE): Use --set.
13068 * tests/atlocal.in: Adjust.
13069 * BUGS: distcheck and check are weak.
13071 2001-08-29 Akim Demaille <akim@epita.fr>
13073 * lib/autotest/general.m4: Use
13074 foo=`(command) 2>/dev/null`
13075 not
13076 foo=`command` 2>/dev/null
13077 (at-devnull): Rename as...
13078 (AT-devnull): this.
13079 (--clean): Remove AT-* files too.
13080 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
13081 Reported by Nicolas Joly.

13085 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

13091 * doc/autoconf.texi (Function Portability): Mention C right shifts.
13093 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>

13096 (AT_INIT): Check for the `times' builtin before using it.
13097 Support test ranges as arguments to the testsuite.
13098 Have -e imply -d as the help text suggested.
13100 2001-08-27 Akim Demaille <akim@epita.fr>
13102 * Makefile.maint: Formatting changes.
13103 (do-po-update, po-update, cvs-update, update): New targets.

13115 * lib/autotest/general.m4 (AT_INIT): Log the command line.
13116 Support `VAR=VAL' as arguments.

13122 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
13123 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
13124 first the build dirs, then the src dirs.

13136 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
13137 `ac_top_builddir' to mimic Automake's vocabulary, which much more
13138 readable.
13139 Adjust callers.
13140 * doc/autoconf.texi (Configuration Actions): Document the vars
13141 available in commands.
13142 Emphasize the risks of collisions in init-cmds.

13173 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
13174 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
13175 -> ac_dir).
13176 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
13177 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.

13205 (AMTAR): Help automake define it.

13207 needed, 1.5 can have a macro and a target with the same name.
13208 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
13209 * m4/strip.m4: New.

13224 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
13225 the name of the directory they're in, instead of the filename,
13226 since version.m4 is now in m4sugar, but m4_acversion must not be
13227 classified as an Autoconf macro.
13228 ($input_m4): Don't qualify the path to m4sugar.
13229 Rather, pass autoconf_dir to m4.
13230 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

13247 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
13248 for config.status'.
13249 Open the log as soon as possible.
13250 Use the same log introduction as configure's.
13252 2001-08-22 Paul Eggert <eggert@twinsun.com>
13254 * doc/autoconf.texi (Indices): New node.
13255 Move indices out of the top level menu and into this submenu.
13257 2001-08-22 Akim Demaille <akim@epita.fr>
13259 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13260 AC_TRY_COMMAND.

13310 AC_COMPILE_IFELSE. Cleanup grep usage.
13312 2001-08-20 Akim Demaille <akim@epita.fr>
13314 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
13315 * NEWS, README, README-alpha, TODO, tests/README: This package is
13316 `Autoconf', not `autoconf' (the executable).
13318 2001-08-20 Akim Demaille <akim@epita.fr>
13320 Info readers seem to need `Index' in the index node title :(
13322 * doc/autoconf.texi: Reverse the 2001-08-15 change which
13323 simplified index node names.
13325 2001-08-20 Akim Demaille <akim@epita.fr>
13327 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
13328 arguments are not literals.

13332 2001-08-20 Akim Demaille <akim@epita.fr>
13334 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
13335 (Examining Syntax) <AC_TRY_COMPILE>

13339 Reported by Werner Lemberg.
13341 2001-08-20 Akim Demaille <akim@epita.fr>

13358 * lib/autoconf/general.m4 (_AC_OUTPUT_COMMANDS): Say what you do.
13359 * m4/atconfig.m4 (AT_CONFIG): $1 is now the directory where the
13360 test suite lives.

13369 Huh!?!?! There are still some user EOF tags used, which prevents
13370 their use in AC_CONFIG_COMMANDS for instance...
13372 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
13373 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

13436 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

13454 * doc/autoconf.texi: Work around Texinfo buglets.
13455 (Transformation Rules): One example is enough, users are expected
13456 to have their brains on. And BTW, use DESTDIR.
13457 (dvar): New macro. Use it.

13501 value.

13509 (cvs-dist): depends upon it.
13511 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
13513 * tests/Makefile.am: Use a clean-local rule to remove
13514 autom4te.cache (it's a directory, not a file.
13515 * Makefile.am: Ditto (but maintainer-clean-local).
13517 2001-08-15 Akim Demaille <akim@epita.fr>
13519 * bin/autom4te.in (@m4_warning): New.
13520 (&handle_m4): Use it.
13521 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
13522 warnings are issued at each run.
13523 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
13524 is in the src tree.
13526 2001-08-15 Akim Demaille <akim@epita.fr>
13528 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
13529 don't waste time running `autoupdate --version' works.
13530 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
13532 2001-08-13 Akim Demaille <akim@epita.fr>
13534 * doc/autoconf.texi (ma): Rename this index as...

13591 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13593 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
13594 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
13595 * doc/autoconf.texi (C Compiler Characteristics): Update
13596 documentation for AC_C_BIGENDIAN.
13598 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13600 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
13601 magic values from an object file when cross-compiling.
13602 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
13604 2001-08-10 Akim Demaille <akim@epita.fr>
13606 * bin/autom4te.in (&handle_output): Don't use `grep' with side
13607 effects.
13608 Suggested by Russ Allbery.
13610 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
13612 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
13613 current $prefix to the sub-configures.
13615 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
13617 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
13618 extension (needed on BeOS). Reported by Guido van Rossum.
13620 2001-08-09 Akim Demaille <akim@epita.fr>
13622 * bin/autom4te.in ($icache): Load it only if older than autom4te.
13624 2001-08-07 Akim Demaille <akim@epita.fr>
13626 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
13627 removed.
13628 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
13629 No need to remove the files before and after the each test, before
13630 each test and at the end of the suite is enough.
13631 Display only the children `times', not the shell's.
13632 If the test failed or was skipped, at-times is not available.
13634 2001-08-07 Akim Demaille <akim@epita.fr>
13636 Always produce testsuite.log, including when there are no
13637 failures. This helps getting information on skipped tests, and
13638 duration of the tests. Err, implement the latter btw.
13640 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
13641 Dump information on the first run of each test.
13642 (AT_CLEANUP): Create `at-times' containing the duration of the
13643 test group.
13645 2001-08-07 Akim Demaille <akim@epita.fr>
13647 The use of `dumpstat' revealed that `len' was used although it
13648 should not. m4_text_wrap was using it, but in the Autoconf world
13649 where it is legal. Hence (i) test M4sh in its own world, not
13650 Autoconf's, and (ii), ahem, fix the bug :)
13652 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
13653 does not like `' instead of [].
13654 (AT_INIT): Forbid `^_?AT_'.
13655 And don't output such tokens.
13656 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
13657 `script.as', and `autom4te.cache'.
13658 Remove `empty' and `macro' which are no longer used.
13659 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
13660 * tests/m4sugar.at: Use it.
13661 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
13663 2001-08-07 Akim Demaille <akim@epita.fr>
13665 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
13667 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
13669 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
13671 2001-08-04 Akim Demaille <akim@epita.fr>
13673 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
13674 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
13675 AC_TRY_LINK.
13676 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
13677 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
13678 (AC_F77_MAIN): Likewise.
13680 2001-08-04 Akim Demaille <akim@epita.fr>
13682 Don't rely on M4sugar outputting the patterns in files, since we
13683 might process the output _without_ running m4, hence without these
13684 files.
13686 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
13687 * bin/autom4te.in (@Request::includes): Remove, unused.
13688 (@Request::source): Rename as...
13689 (@Request::input): this.
13690 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
13691 (&handle_output): Fetch the patterns from the traces.
13692 `$forbidden' and `$allowed' are constant: use m//o.
13693 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
13694 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
13696 2001-08-04 Akim Demaille <akim@epita.fr>
13698 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
13699 autoconf', i.e., in addition to caching traces, cache the output.
13701 * bin/autom4te.in (Request::cache): Rename as...
13702 (Request::id): this.
13703 ($cache, $icache, $tcache, $ocache): New.
13704 (&handle_m4): Save M4 output in the cache instead of $tmp.
13705 (&handle_output): Adjust.
13706 (&up_to_date_p): Check that the output cache is up to date too.
13707 (top level): Run `&handle_m4' iff force or the cache is invalid.
13708 Run `&handle_output' if the output cache is more recent.
13710 2001-08-04 Akim Demaille <akim@epita.fr>
13712 * bin/autom4te.in ($force): New.
13713 (&parse_args, &print_usage): -f, --force is a new option.
13714 (&handle_output): CPP directives might have spaces after `#'.
13715 (&parse_args): The first file only can be frozen.
13717 2001-08-04 Akim Demaille <akim@epita.fr>
13719 Don't let autom4te compute the `include' traces several times:
13720 first check that the trace cache file is up to date, and then
13721 compare its timestamp with that of the output.
13723 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
13724 the preamble. Don't require 5.005 as Autom4te::General does it,
13725 and better yet (use `use', not `require'!).
13726 * lib/Autom4te/Struct.pm: Rename the last occurrences of
13727 Class::Struct as Autom4te::Struct.
13728 * lib/Autom4te/General.pm (File::stat): Use it.
13729 (&mtime): New, export it.
13730 * bin/autom4te.in: Use it.
13731 Declare `$req' is invalid if it is outdated.
13732 Don't declare it valid before saving it if something went wrong.
13734 2001-08-04 Akim Demaille <akim@epita.fr>
13736 Autom4te shall not encode Autoconf data, and preselecting traces
13737 must be proposed to the users.
13739 * bin/autom4te.in (@required_trace): Remove.
13740 (@preselect): New.
13741 (&parse_args, &print_usage): -p, --preselect is a new option.
13742 (&up_to_date_p): Adjust.
13743 * bin/autoconf.in: Preselect some Autoconf macros.
13745 2001-08-04 Akim Demaille <akim@epita.fr>
13747 * tests/tools.at (autoconf --trace: user macros): Check traces on
13748 macros invoked without arguments, and macros invoked with multiple
13749 lines arguments.
13751 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
13753 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
13754 arguments.
13756 2001-08-03 Akim Demaille <akim@epita.fr>
13758 * bin/autoconf.in ($@): Work around the usual sh bug.
13759 From Nicolas Joly.
13761 2001-08-03 Akim Demaille <akim@epita.fr>
13763 Clean up the handling of the M4 builtins tracing exception.
13765 * bin/autom4te.in (Request::request): Don't complete M4 builtins
13766 trace requests.

13768 (@m4_builtin): this.
13769 (%m4_builtin_alternate_name): New.
13770 (&parse_args): Complete the trace requests with alternate names.
13771 (&handle_traces): Hence no longer do it here.
13772 (&trace_requests): Remove, unused.
13774 2001-08-03 Akim Demaille <akim@epita.fr>
13776 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
13777 m4_if, and m4_wrap.
13779 2001-08-03 Akim Demaille <akim@epita.fr>
13781 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
13782 (m4_divert_pop): Dump the whole diversion stack when a diversion
13783 mismatch happens.
13784 * bin/autom4te.in (&handle_output): Remember of the first
13785 occurrence of a possibly undefined macro, not the last.
13786 Complain about the possibly undefined macros in the same order as
13787 the appear in the output.
13788 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
13789 * tests/tools.at (autoconf: forbidden tokens, basic)
13790 (autoconf: forbidden tokens, exceptions): No longer sort
13791 autoconf's stderr, as it is now deterministic.
13792 Check that `dnl' is caught.
13794 2001-08-01 Akim Demaille <akim@epita.fr>
13796 * configure.ac: Bump to 2.52c.
13798 2001-08-01 Akim Demaille <akim@epita.fr>

13808 2001-08-01 Akim Demaille <akim@epita.fr>
13810 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
13811 `die'.
13812 (&END): New.
13813 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
13814 `END', as `Autom4te::General::END' will be triggered.
13815 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
13816 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

14208 compiler, not the preprocessor.

14215 2001-07-03 Akim Demaille <akim@epita.fr>

14245 dummy alternate main is required even if the user provides her own
14246 'main'.

14248 provide an alternate 'main' function name, using the 'main' from
14249 the Fortran libraries.
14250 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
14251 cross-language link tests can be performed successfully.
14252 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
14253 after $LIBS, for consistency; this should be the general rule since

14257 2001-06-29 Pavel Roskin <proski@gnu.org>

14260 at-stdout and at-stderr instead of removing the newline
14261 from the echo output, which is not guaranteed to work.
14263 2001-06-28 Jens Petersen <petersen@redhat.com>
14265 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to
