3 Add a `--clean' option for autoconf, autoheader, autoreconf and
4 autom4te.
5 * bin/autoconf.as, bin/autoheader.in, bin/autoreconf.in,
6 bin/autom4te.in: New option `--clean'.
7 * NEWS: Mention it.
8 * bin/autoreconf.in (&run_make): New.
9 (&autoreconf_current_directory): Use it. Honor the $clean variable.
10 * lib/Autom4te/General.pm ($clean): New boolean value.
11 (getopt): Handle `--clean'.
12 * lib/Autom4te/FileUtils.pm ($SIMPLE_BACKUP_SUFFIX): Export it.
13 * tests/torture.at: Test the new feature.
14 * doc/autoconf.texi (autoconf Invocation, autoreconf Invocation)
15 (autoheader Invocation, autom4te Invocation): Document the new option.
17 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
19 Ignore configure --help* errors due to LINENO-impaired shells.
20 * tests/torture.at (Configuring subdirectories, Deep Package):
21 In the --help* tests in read-only trees, make `.' temporarily
22 writable again for the `stderr' file, and ignore errors due to
23 the attempt to write configure.lineno.
24 Report by Patrick Welche.
26 2007-11-10 Jim Meyering <meyering@redhat.com>
28 Generate package.m4 in build-dir, not srcdir.
29 * tests/Makefile.am (package.m4): Adjust target.
30 Don't redirect directly to $@.
31 (CLEANFILES): Add package.m4.
32 ($(TESTSUITE)): Depend on just-built package.m4, not the one
33 in $(srcdir).
34 When running $(AUTOTEST), search "." before searching $(srcdir).
36 Avoid a race condition that would make parallel "distclean" fail.
37 * tests/Makefile.am (distclean-generic): Replace the default,
38 automake-provided rule with an identical one, but with an additional
39 dependency on distclean-local. Simply adding the dependency would
40 cause automake not to emit the rule at all.
41 * BUGS: Building with -jN works, now.
43 Distribute git-version-gen.
44 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
45 since GNUmakefile is distributed, and requires it for dist* rules.
47 Remove two more generated files from version control.
48 * INSTALL: Remove generated file.
49 * lib/autoscan/autoscan.list: Remove generated file.
51 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
53 * GNUmakefile (PATH): Remove stray apostrophes; they become
54 part of PATH, which isn't wanted here.
56 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
58 New config files output variable `top_build_prefix'.
59 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
60 `top_build_prefix'.
61 * doc/autoconf.texi (Preset Output Variables): Document it.
62 * NEWS: Update.
63 Report by Bob Friesenhahn.
65 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
66 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
67 function, to parametrize arithmetic with expr vs. the shell.
68 Use it where possible.
69 Suggestion by Benoit Sigoure.
71 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
73 Adjust the documentation of autotest WRT atlocal.
74 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
75 when using Automake, to write a rule to produce atlocal, since it's
76 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
77 distributed, not atconfig.in.
79 2007-11-04 Eric Blake <ebb9@byu.net>
81 Update list information.
82 * README: Mention new autoconf-commit list.
83 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
85 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
87 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
89 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
91 * build-aux/.gitignore: Ignore mkinstalldirs.
93 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
95 2007-11-03 Jim Meyering <meyering@redhat.com>
97 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
98 * build-aux/git-version-gen: This syncs from coreutils.
100 Adjust the build procedure so "make check" works reliably.
101 * README-hacking: Include an extra step between "make" and
102 "make check" to ensure that the latter passes.
104 Use just-built tools, when possible.
105 * GNUmakefile (PATH): Set and export here, ...
106 (dummy): ... rather than here.
108 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
109 and Andreas Schwab <schwab@suse.de>
111 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
112 exit status bug.
114 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
116 * configure.ac (AC_PREREQ): Require version 2.60, for
117 AC_PROG_SED, AC_PROG_GREP.
119 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
120 and Jim Meyering <meyering@redhat.com>
121 and Andreas Schwab <schwab@suse.de>
122 and Eric Blake <ebb9@byu.net>
124 Document a bug in GNU Bash with compound commands and redirections.
125 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
126 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
127 workaround.
129 2007-11-03 Eric Blake <ebb9@byu.net>
131 Support m4 1.4.5 in testsuite.
132 * tests/torture.at (Define a newline): Exclude line numbers in
133 error message.
134 Reported by Ralf Wildenhues.
136 2007-11-03 Jim Meyering <meyering@redhat.com>
138 Remove automake-provided files from version control.
139 * build-aux/elisp-comp: Remove file.
140 * build-aux/install-sh: Remove file.
141 * build-aux/missing: Remove file.
142 * build-aux/mdate-sh: Remove file.
143 * build-aux/.gitignore: New file.
144 Suggestion from Ralf Wildenhues.
146 2007-11-03 Eric Blake <ebb9@byu.net>
148 Adjust version comparison to account for git snapshot numbers.

158 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
159 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
160 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
161 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
162 Suggested by Paul Eggert.
164 2007-10-28 Jim Meyering <meyering@redhat.com>
166 * README-hacking: Autoconf, Automake, and Perl are required to build.
167 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
169 2007-10-28 Jim Meyering <meyering@redhat.com>
171 README-hacking: Recommend running autoreconf -vi.
172 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
173 so that we use just-built tools when they're available.
174 Suggestions from Ralf Wildenhues.
176 2007-10-28 Jim Meyering <meyering@redhat.com>
178 Make inter-release --version output more useful.
180 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
181 which indicates that it is built using the 19th change set
182 (in _some_ repository) following the "v2.61a" tag, and that 58dd
183 is a prefix of the commit SHA1.
184 * build-aux/git-version-gen: New file.
185 * configure.ac: Run it to set the version.
186 (AM_INIT_AUTOMAKE): Don't check NEWS here.
187 * Makefile.am (dist-hook): Arrange so that .version appears only
188 in distribution tarballs, never in a checked-out repository.
189 * .gitignore: Add .version here, too. Just in case.
190 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
191 not configure.ac, now that the version number changes automatically.
193 Ensure that $(VERSION) is up to date for dist-related targets.
194 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
195 git-version-gen doesn't match $(VERSION), but only for dist targets.
197 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
199 Fix `Deep Package' failure with a configure script early in PATH
200 * tests/torture.at (Deep Package): Add `.' early in PATH.
201 Report by Jim Meyering.

225 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
226 and Eric Blake <ebb9@byu.net>
228 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
229 problem reported by Bruno Haible in
230 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
232 2007-10-22 Eric Blake <ebb9@byu.net>
234 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
235 preprocessor.
237 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
239 Don't check for bug in HP-UX 11.00 cpp.
240 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
241 Use -1ull rather than -1u, since that causes problems with gnulib; see
242 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
244 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

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

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

312 array of banner text from a special diversion.
313 <PARSE_ARGS_END>: No longer need awk to find banners.
314 <TESTS>: Banners are no longer processed by main driver loop, so
315 we no longer need case statement.
316 (AT_BANNER): Rewrite to populate new diversion.

1468 (the C terminology), not type-ids (the C++ term). C++ types
1469 must not be anonymous.
1470 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
1471 for C++; this drops support for anonymous struct and union types,
1472 which were problematic anyway.
1473 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
1474 for C++.
1476 2007-04-12 Jim Meyering <jim@meyering.net>
1478 * doc/autoconf.texi (Libraries): Typo fix: insert missing "in".

1488 * doc/autoconf.texi (Generic Types): Document the restrictions
1489 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
1490 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
1491 with objects too. Document the restrictions on its use.
1492 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
1493 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
1494 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
1495 works but the latter doesn't, then it's a valid type.
1496 This lets people use function types and so forth.
1497 For C++ there doesn't seem to be a simple solution, so leave it alone.
1498 (AC_CHECK_SIZEOF): Allow argument to be a variable.
1499 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
1500 AC_CHECK_TYPE; that wasn't documented or necessary.
1502 2007-04-11 Stepan Kasal <kasal@ucw.cz>
1504 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

1543 more pitfalls.
1545 2007-03-23 Paul Eggert <eggert@cs.ucla.edu>
1547 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
1548 checks for unsigned long long int.
1550 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
1552 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
1553 nonstandard grep R.E. escape sequences.
1555 2007-03-17 Jim Meyering <jim@meyering.net>
1557 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
1558 (Limitations of Usual Tools): Also list \< and \>, and mention that
1559 HP-UX's grep, like the one from Solaris, does not support that syntax.
1561 2007-03-09 Stepan Kasal <kasal@ucw.cz>
1563 * doc/autoconf.texi (Specifying Names): `--host' does not
1564 change the build type.
1566 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
1568 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
1569 suggests AC_CONFIG_HEADERS.
1570 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using

1576 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Fix typo "__LITLE_ENDIAN__".
1577 Problem reported by Paolo Bonzini in:
1578 http://lists.gnu.org/archive/html/autoconf-patches/2007-02/msg00024.html
1579 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
1580 universal binaries. Problem reported by Elias Pipping.
1582 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
1584 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
1585 * doc/autoconf.texi (C Compiler): Document this. There is a new
1586 extra argument ACTION-IF-UNIVERSAL.
1587 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
1588 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
1589 Reindent for sanity's sake.
1591 2007-02-24 Eric Blake <ebb9@byu.net>
1593 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
1594 copyright.

1622 carriage return.
1623 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
1624 with traditional Awk and begin.
1625 * tests/torture.at (Limitations of Builtins): Document the problem

1659 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
1661 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
1662 latest version.
1663 (Shell Substitutions): Note problems with @{var:=value} etc.
1664 Add a new section for problems with @{#var} etc. Problem noted
1665 by Ralf Wildenhues. See:

1668 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1670 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
1671 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
1672 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
1673 substitution will still be done by the special code.
1674 Report by Jim Meyering.
1676 * doc/autoconf.texi (File System Conventions): Mention that

1693 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
1695 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1697 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
1698 early on the reader side, drop stderr of the input to avoid
1699 `broken pipe' error output; this may happen even with shell
1700 builtin `echo' of some bash versions. Reports by Ian Macdonald
1701 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
1703 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1705 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

1713 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
1715 Fix some wording problems noted by Paolo Bonzini in:
1716 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
1717 * doc/autoconf.texi (Signed Overflow Examples): Give more
1718 discussion about the allow_superuser_privileges example,
1719 and change it a bit to make things clearer.
1720 (Optimization and Wraparound): Clarify whether the compiler
1721 will generate an infinite loop for the example derived from
1722 Autoconf's mktime test.
1723 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
1724 Also, clarify unsigned multiplication overflow.
1726 2007-01-04 Eric Blake <ebb9@byu.net>
1728 * bin/Makefile.am (RELEASE_YEAR): New macro.
1729 (edit): Use it to supply correct copyright year to scripts.
1730 * bin/autoconf.as (version): Use it.
1731 * bin/autoheader.in ($version): Likewise.
1732 * bin/autom4te.in ($version): Likewise.
1733 * bin/autoreconf.in ($version): Likewise.
1734 * bin/autoscan.in ($version): Likewise.
1735 * bin/autoupdate.in ($version): Likewise.
1736 * bin/ifnames.in ($version): Likewise.
1738 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
1740 * doc/autoconf.texi (Integer Overflow): Revised based on today's
1741 feedback. The most important changes document what happens when
1742 you convert an out-of-range value to a signed integer type, and
1743 say that (sum < a) != (b < 0) reliably detects overflow when sum =
1744 a + b.
1746 * doc/autoconf.texi (Integer Overflow): Greatly expand and
1747 rewrite, taking notions from the recent discussion on the gcc and
1748 autoconf mailing lists; please see
1749 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
1750 and follow the many links.
1751 (Integer Overflow Basics, Signed Overflow Examples):
1752 (Optimization and Wraparound, Signed Overflow Advice):
1753 (Signed Integer Division): New sections.
1755 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
1757 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
1758 preprocessor macro arguments in traced name.
1759 * doc/autoconf.texi (Defining symbols): Document longstanding
1760 support for AC_DEFINE-ing macros with arguments, and document
1761 behavior when the same variable has multiple AC_DEFINEs.
1762 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
1763 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
1764 macros directly, giving much shorter and simpler code.
1766 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
1768 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
1769 space before "$ac_configure_args" to prevent a 'config.status
1770 --recheck' failure if ac_configure_args doesn't contain a leading
1771 space. This works around a problem with the XEmacs configure.ac,
1772 which uses the (undocumented) ac_configure_args variable
1773 inconsistently with Autoconf.
1775 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
1777 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
1778 Include <limits.h>, and use its INT_MAX to rewrite the
1779 j loop so that it does not overflow 'int'. Problem reported by
1780 Ralf Wildenhues in
1781 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
1782 Play it safe by shifting left by 1 rather than multiplying by 2,
1783 as GCC is less likely to optimize this away when the value
1784 is signed (when it assumes overflow leads to undefined behavior).
1785 Also, don't assume time_t uses two's complement.
1787 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1789 * tests/torture.at (Substitute a 2000-byte string): Avoid using
1790 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
1791 dumps core on it. Report by Tim Rice.
1793 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1795 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
1796 --disable-option-checking to --help output even when
1797 AC_PRESERVE_HELP_ORDER is not used.
1798 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
1799 --with argument, rather than argument with [-.] replaced by
1800 underscores.
1801 * NEWS: Fix typo in previous change; the news was in the
1802 wrong section.
1804 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
1806 * NEWS: Warnings are now generated by default for unknown
1807 --enable-* and --with-* options.
1808 * doc/autoconf.texi (Option Checking): Renamed from
1809 (Configure Option Checking). Tighten up the wording a bit.
1810 (External Software, Package Options): Cross-reference to Option
1811 Checking, and use this to shorten our section.
1812 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
1813 "$x" to test "x$foo" != x.
1814 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
1815 Don't warn if $enable_option_checking is "no".
1816 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
1817 ac_unrecognized_opts to the empty string.
1818 Don't echo the unrecognized opts, as this might mishandle
1819 backslashes or leading -.
1820 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
1821 usage next to the other --disable-FEATURE options in the
1822 help string.
1824 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1826 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
1827 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
1828 Print warning for unrecognized --with and --enable options
1829 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
1830 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
1831 Disable option checking when subdirs are configured.
1832 (AC_OUTPUT): If warnings are enabled, print warning about
1833 unrecognized --with and --enable options at the end of
1834 the configure output (as well as at the beginning).
1835 * doc/autoconf.texi (Option Checking): New node.
1836 Document new option warning functionality.
1838 2006-12-16 Eric Blake <ebb9@byu.net>
1840 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
1841 * NEWS: Start news for current version.
1843 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
1845 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1846 Define HAVE_GETMNTENT to 1, not to the empty string.
1847 Problem originally reported by Jochen Friedrich in
1848 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
1850 This change prompted by a problem report by Andrey Simonenko in
1851 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
1852 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
1853 object-like macros only, in the traditional portable character
1854 set.
1855 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
1856 Warn about attempts to define things that are not identifiers.
1857 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
1858 awful hack that AC_DEFINEd macro names containing parentheses.
1860 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
1862 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
1863 too drastic, even if Texinfo in theory requires it for info mode.
1865 (config.status Invocation): Renamed back from Recreating a
1866 Configuration).
1867 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
1868 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
1870 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1872 * NEWS: Version 2.61a.
1874 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1875 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1877 * NEWS: Document changes with echo and printf, and the lack
1878 of limits on the total size of multi-line values of substituted
1879 variables, and the AC_FUNC_FSEEKO fix.
1881 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
1883 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
1884 Writing configure.ac.
1885 (Autoconf Input Layout): Renamed from configure.ac Layout.
1886 (Recreating a Configuration): Renamed from config.status Invocation.

1889 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
1890 (Writing Testsuites): Renamed from Writing testsuite.at.
1891 (Autom4te Cache): Renamed from autom4te.cache.
1893 * BUGS: Remove mention of VPATH problem, since it's now documented
1894 not to be a bug in the Autoconf build procedure itself, but rather
1895 a problem with the proprietary `make' programs.
1897 * doc/autoconf.texi (Build Directories): Add a cross reference
1898 to VPATH and Make.
1900 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
1901 * doc/standards.texi: Sync from gnulib.

1904 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
1905 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
1906 generated automatically.
1908 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
1910 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
1911 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
1912 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
1914 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1916 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
1917 `CEOF$ac_eof' special marker, the awk script cannot contain a
1918 line matching `^CEOF', so this is not needed any more.
1919 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
1920 special marker in the test.
1922 2006-12-06 Stepan Kasal <kasal@ucw.cz>
1924 * tests/tools.at (autom4te preselections): Use `find -newer';
1925 remove one of the sleeps.
1927 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
1928 more readable, using ...
1929 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
1931 * doc/autoconf.texi (autoheader Invocation): Do not double-
1932 quote the parameter of `AH_BOTTOM' in the example.
1934 2006-12-05 Stepan Kasal <kasal@ucw.cz>
1936 * doc/autoconf.texi (Configuration Headers): Remove the
1937 example with multiple input files.
1938 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
1939 multiple input files.
1941 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1943 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
1944 creating the awk substitution script, handle one input line at a
1945 time, so that the maximum length of a substituted (multi-line)
1946 value is not limited by the size of the sed pattern space.
1947 The trade-off is a slightly repetitive sed script.
1948 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
1949 can only have up to 7 characters, due to Solaris 10 /bin/sed.
1950 * tests/torture.at (Substitute a 2000-byte string): Increase the
1951 test with several long lines, they should not be caught by sed
1952 limits any more.
1954 * tests/tools.at (autom4te preselections): New test, to flag
1955 entries missing from autom4te.cfg.
1956 Report by David Byron <dbyron@hheld.com>.
1958 * tests/torture.at (Substitute a 2000-byte string): Actually use
1959 AC_PROG_AWK, so the last change works as intended.
1960 (Substitute and define special characters): Likewise.
1961 (Substitute a newline): Likewise.
1963 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
1964 instead of `awk' consistently.
1965 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
1966 * tests/torture.at (Torturing config.status): Test both the
1967 result of AC_PROG_AWK and plain awk.
1968 (Substitute a 2000-byte string): Likewise.
1969 (Substitute and define special characters): Likewise.
1970 (Substitute a newline): Likewise.
1972 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
1974 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
1975 can be assigned to a function pointer. Problem reported by
1976 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
1977 part of a patch by Ralf Wildenhues in that same bug report.
1979 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
1981 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
1982 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
1984 2006-12-01 Eric Blake <ebb9@byu.net>
1986 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
1987 cross-compiling from cygwin to mingw.
1988 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
1989 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
1990 to lib/autoconf/c.m4.
1992 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1994 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
1995 string for more reliable failure. Wrap the entire test that
1996 causes the broken Solaris printf to dump core, in a subshell,
1997 so the segmentation fault message is reliably suppressed.
1998 Fix shell expansion errors by using /usr/ucb/echo always;
1999 avoid an error on systems without it by another subshell.
2000 Avoid m4 expansion of `$1'. Set the zeroth argument of the
2001 subshell-$as_echo to `as_echo', for better error message.
2003 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2005 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
2006 `BASH_SOURCE' contain a newline, set them to empty, as they may
2007 not be unset.
2009 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
2011 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
2012 years and is too hard to maintain now. The last straw was
2013 reported by Jerker Baeck in
2014 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
2015 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
2016 * doc/autoconf.texi (Particular Functions): Move
2017 AC_FUNC_SETVBUF_REVERSED from here...
2018 (Obsolete Macros): ... to here. Say that it does nothing now.
2019 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
2020 Turn into (almost) a no-op.
2022 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
2023 (AC_C_VOLATILE):
2024 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
2025 These macros are obsolescent and new applications shouldn't need them.
2026 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
2027 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
2028 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
2029 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2030 (AC_FUNC_VPRINTF): Likewise.
2031 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
2032 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
2033 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
2035 * doc/autoconf.texi (Setting Output Variables): Mention that
2036 @VAR1@VAR2 has unspecified behavior. Problem reported by
2037 Ralf Wildenhues.
2038 * NEWS: Mention this.
2040 * Makefile.am: Put only a single '#' into the copyright notice,
2041 so that it's also present in the output file. Standardize wording
2042 in makefile copyright notices to match GNU coding standards.
2043 * bin/Makefile.am: Likewise.
2044 * doc/Makefile.am: Likewise.
2045 * lib/Makefile.am: Likewise.
2046 * lib/freeze.mk: Likewise.
2047 * lib/autoconf/Makefile.am: Likewise.
2048 * lib/autoscan/Makefile.am: Likewise.
2049 * lib/autotest/Makefile.am: Likewise.
2050 * lib/m4sugar/Makefile.am: Likewise.
2051 * man/Makefile.am: Likewise.
2052 * tests/Makefile.am: Likewise.
2053 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
2054 one-line file.
2056 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2058 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
2059 in the sed script that mangles the awk script: delete up to the
2060 first exclamation mark only.
2061 * tests/torture.at (Substitute and define special characters):
2062 Test '!' too.
2064 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2066 Rewrite config files generation: avoid quadratic growth in
2067 the number of substituted variables by using awk instead of sed
2068 for the bulk of the substitutions.
2069 * NEWS: Mention this.
2070 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
2071 forbidden in the output (and thus input) file.
2072 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
2073 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
2074 generate just one large awk script for substitutions,
2075 eliminating much of the earlier complexity, while adding some
2076 new complexity. Only expand the substitution templates at
2077 configure time, for smaller configure script size. If
2078 _AC_SUBST_FILES are used, test 'awk' for working getline support
2079 at config.status time. If absent, interpolate through the
2080 shell. The awk script was written with much help
2081 from Paolo Bonzini and Paul Eggert.
2082 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
2083 (_AC_SED_FRAG_NUM): Likewise.
2084 (_AC_SUBST_CMDS): Renamed from...
2085 (_AC_SED_CMDS): ...this.
2086 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
2087 * tests/torture.at (Substitute a 2000-byte string): Also
2088 substitute a line with 1000 words, and a variable with several
2089 long lines.
2090 (Substitute and define special characters): Test awk special
2091 characters, and put substitution input strings `@foo@' in the
2092 output, to test that no recursion happens; test several other
2093 combinations from Paolo Bonzini.
2095 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
2097 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
2098 that replaced echo with AS_ECHO where this wasn't necessary.
2099 Problem reportd by Ralf Wildenhues.
2100 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
2101 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
2102 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
2104 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2106 * lib/freeze.mk (GREP): Removed, no need to initialize this.
2108 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
2110 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
2111 that traditional Awk lacks 3-arg "split". It has it.
2112 Mention that FS must be a single character, and a few other
2113 99-byte limits of traditional Awk.
2114 Mention that if (i in a) doesn't work with traditional Awk.
2116 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
2118 * tests/autotest.at (BSx641-newline in command):
2119 (BS-BS-newline in command, BSx640-newline in command):
2120 (Newline-CODE-BS-newline in command):
2121 (Single-quote-BS-newline in command):
2122 (Single-quote-newline-BS-newline in command):
2123 Use printf '%s\n' instead of echo, for portability to hosts
2124 where echo interprets backslashes. This will break on hosts
2125 that lack printf, but for now let's assume all such hosts
2126 are dead (if not, we should get reports of test failures).
2128 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2130 'echo' has some portability problems, when given a first argument
2131 with a leading '-', or when given any argument containing '\'.
2132 Avoid using 'echo' in these cases.
2133 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
2134 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.

2136 * lib/autotest/general.m4 (AT_INIT): Likewise.
2137 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
2138 argument might be unportable.

2157 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
2158 * bin/autoconf.as: Redo verbose flag implementation, as the old
2159 scheme wouldn't work with AS_ECHO.
2160 * lib/autotest/general.m4 (AT_INIT): Likewise.
2161 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
2162 Don't use ECHO_T, since ECHO_N is now reliable.
2163 * lib/autotest/general.m4 (AT_INIT): Likewise.
2164 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
2165 rather than using a here-document to put the script into a file.
2166 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
2167 use AS_ECHO.
2168 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
2169 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
2170 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
2171 bug, but we might as well stop using ECHO_N and ECHO_C internally.
2172 * lib/autotest/general.m4 (AT_SETUP): Likewise.
2173 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
2174 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2175 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
2176 operand, as AS_ECHO requires. Avoid double file name expansion.
2177 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
2178 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
2179 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
2180 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
2181 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
2182 Double-quote strings that would otherwise contain M4 comments.
2183 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
2185 * configure.ac (AC_INIT): Bump to 2.61a.
2186 * NEWS: Likewise.
2188 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2190 Version 2.61.
2192 * configure.ac (AC_INIT): Bump to 2.61.
2193 * NEWS: Likewise.
2195 * tests/autotest.at (Macro with backslash in a test title):
2196 Comment out for now, as this tests neither fails nor passes
2197 reliably. Problem reported by Ralf Wildenhues.
2199 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
2201 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
2202 in previous change, which caused test failures.
2204 2006-11-16 Stepan Kasal <kasal@ucw.cz>
2206 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
2207 code for --enable, --disable, --with, and --without to...
2208 (_AC_INIT_PARSE_ENABLE): ... a new macro.
2209 * doc/autoconf.texi (Package Options):
2210 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
2212 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
2214 Import these changes from config via gnulib:
2216 2006-11-15 Ben Elliston <bje@gnu.org>
2218 From Josselin Mouette <joss@debian.org>:

2273 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
2275 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
2276 benefit of platforms like Solaris+GCC where it is common to have a
2277 non-working g++ installation.
2279 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2280 and Joel E. Denny <jdenny@ces.clemson.edu>
2281 and Paul Eggert <eggert@cs.ucla.edu>
2283 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
2284 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
2285 ./micro-suite.
2287 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2289 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
2290 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
2291 Imported from a similar patch to gnulib by Bruno Haible.
2293 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2295 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

2303 Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
2304 Matthew Woehlke.
2306 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2308 * tests/torture.at (Configuring subdirectories): Do not skip
2309 Automake 1.10 nor future Automake 11.1 (sic).
2311 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
2312 and Stepan Kasal <kasal@ucw.cz>
2314 Handle special characters in test case titles correctly.
2315 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
2316 properly.
2317 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.

2321 (Backquote in a test title,
2322 Single-quote in a test title,
2323 Double-quote in a test title): Don't expect failure anymore.
2324 (Backslash in a test title): Put a non-whitespace character after the
2325 backslash so that Bourne shells might actually see it as an escape
2326 sequence.
2327 (Brackets in a test title,
2328 Pound in a test title,
2329 Comma in a test title,
2330 Quoted Macro in a test title,

2334 Macro with double-quote in a test title,
2335 Macro with backslash in a test title): New tests expected to fail.
2336 * tests/torture.at (#define header templates): M4-quote this title in
2337 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
2338 The visible effect was a stray [] in the testsuite output.
2340 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2342 * doc/autoconf.texi (Limitations of Builtins): Do not invoke

2345 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
2347 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
2348 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
2349 5363) simply issues a warning when dividing by zero at compile
2350 time. Problem reported by Elias Pipping.
2352 2006-10-26 Eric Blake <ebb9@byu.net>
2354 * THANKS: Update.
2355 * doc/autoconf.texi (Evaluation Macros): Improve the example to
2356 show effect on macros that expand with commas.
2357 Reported by Joel E. Denny.
2359 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
2360 Also work with M4 1.4.8.
2362 2006-10-25 Paul Eggert <eggert@cs.ucla.edu>
2364 * doc/autoconf.texi (Slashes): Document Tru64 4.0 bug reported by
2365 Jim Meyering.

2370 `--force' always rewrites the output file.
2372 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
2374 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm

2381 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
2383 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2384 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
2385 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
2386 reported by Nelson H. F. Beebe for Coreutils 6.4.
2388 * tests/tools.at (autoconf --trace: user macros): Remove test
2389 for tracing multiline macros, since m4 1.4.7a uses a different
2390 way to number lines. Problem reported by Ralf Wildenhues.
2392 2006-10-24 Stepan Kasal <kasal@ucw.cz>
2394 * bin/autom4te.in (handle_m4): Do not redirect stdin to
2395 /dev/null since the heuristics for interactive behaviour was
2396 fixed in CVS m4.
2398 * bin/autom4te.in: With --force, always refresh the output
2399 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

2418 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
2419 AC_CACHE_CHECK_INT, since it's no longer public.
2420 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
2421 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
2423 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2425 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
2427 2006-10-19 Eric Blake <ebb9@byu.net>

2449 2006-10-14 Stepan Kasal <kasal@ucw.cz>
2451 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
2452 looking for special shell characters.
2453 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
2454 macro defined by AS_VAR_PUSHDEF before passing it as a
2455 parameter.
2456 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
2457 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

2466 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
2468 (Imported from Automake.)
2469 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
2470 which incorrectly sets the mode of an existing destination
2471 directory. In some cases the unpatched install-sh could do the
2472 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
2473 system. We hope this is rare in practice, but it's clearly worth
2474 fixing. Problem reported by Alex Unleashed in
2475 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
2476 Also, don't bother to check for -m bugs unless we're using -m;
2477 suggested by Stepan Kasal.
2479 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
2481 Import this change from Automake:
2483 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
2484 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
2485 is enabled by default with gnu and gnits strictness.
2486 Report from Bruno Haible.
2488 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
2489 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
2490 gnu and gnits modes.
2492 Import this change from Config:
2494 2006-09-20 Ben Elliston <bje@gnu.org>
2495 * build-aux/config.sub (score, score-*): New.
2497 Import this change from Gnulib:
2499 2006-09-16 Karl Berry <karl@gnu.org>
2500 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
2501 to avoid sectioning errors.
2503 Import these changes from Texinfo:
2505 2006-10-04 Karl Berry <karl@gnu.org>
2506 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
2507 (\quoteexpand): rename to \rquoteexpand.
2508 (\codequoteleft): new def, to look for @set codequotebacktick.
2509 (\lquoteexpand, \quoteexpand): new defs.
2510 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
2511 (\code): must use new \...Char values, since now ` is active.
2513 2006-08-26 Karl Berry <karl@gnu.org>
2514 * build-aux/texinfo.tex (\textdegree): New command.
2516 2006-08-12 Karl Berry <karl@gnu.org>
2517 * build-aux/texinfo.tex (error \box0): smaller font.

2521 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
2523 2006-10-13 Stepan Kasal <kasal@ucw.cz>
2525 * doc/autoconf.texi (Autoheader Macros): Warn that the text
2526 added to the template can get mangled.
2528 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2530 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
2531 include the default headers, and redefine obstack_chunk_alloc
2532 and obstack_chunk_free. Fixes false failure with glibc.
2534 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
2536 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
2537 for backward compatibility with Libtool 1.5.22. Problem reported
2538 by Ralf Wildenhues.
2540 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2542 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
2543 AC_PROG_CC.
2544 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
2546 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
2548 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
2549 the NonStop platform.
2550 * doc/autoconf.texi (Posix Variants): Likewise.
2551 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
2553 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
2554 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
2555 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
2556 Use a better substitute, by inspecting the output of "ls"
2557 rather than just using ":".
2558 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
2559 rather than AS_EXECUTABLE_P, since we needn't worry about
2560 non-regular files here.
2562 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
2563 due to configuration hassles with this. See Tonya Underwood's report
2564 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
2565 * doc/autoconf.texi (Special Shell Variables): Likewise.
2567 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
2568 Stepan Kasal <kasal@ucw.cz>

2571 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
2573 2006-10-11 Stepan Kasal <kasal@ucw.cz>
2575 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
2576 initialization which is not inherited through the environment
2577 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
2578 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
2580 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
2582 * doc/autoconf.texi (Limitations of Usual Tools): Describe
2583 problems with mkdir -p -m.
2585 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
2587 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
2588 comment about ac_cpp_err; it was incorrect, and anyway
2589 ac_cpp_err is being removed below.
2590 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
2591 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
2592 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
2593 nobody uses it.
2594 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
2595 with werror_flag and conftest.err and so forth. This is more
2596 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
2597 and anyway the user shouldn't normally want to see this gorp logged.
2598 Problem reported by Ralf Wildenhues.
2599 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
2600 empty, not 'no', since the rest of the code uses 'test -z'.
2602 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
2604 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2605 Use a single call to AC_DO_TOKENS rather than multiple, for
2606 efficiency.
2607 (_AC_LINK_IFELSE): Test that resulting file is executable.
2608 Problem reported by mwoehlke in
2609 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
2611 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
2612 than creating a file to use with test -x; this is much faster.
2614 2006-10-02 Bruno Haible <bruno@clisp.org>
2616 * lib/autom4te.in (Automake-preselections): Add
2617 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
2619 2006-09-27 Stepan Kasal <kasal@ucw.cz>
2621 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
2622 standard error, `experr' should be used, not `expout'.
2624 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2626 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
2627 fseeko testing program twice; just use the earlier result.
2628 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2629 Set cache var to 'unknown' (not 'no') if leaving the macro unset
2630 still doesn't let the program compile.
2631 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
2632 failed.
2634 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
2635 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
2636 include it, without including anything else.
2637 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
2638 expressions.
2639 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
2641 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2643 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
2644 `error.h', and include it, for a `error_at_line' prototype.
2645 Use a nonempty format string in the link test.
2646 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
2647 for a declaration of wait3.
2649 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2651 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
2652 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
2653 can apply to constants too, and that it checks for macro defns.
2654 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
2655 and simply cast the identifier to void. This handles structure
2656 values. Problem reported by Ralf Wildenhues.
2657 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
2659 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2661 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
2662 structure, and function symbols.
2664 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2666 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
2667 member.

2679 warnings (uninitialized value).
2680 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
2681 present.
2682 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add

2712 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
2713 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
2714 --error-output, to avoid warnings with M4 2.0.
2716 2006-09-19 Stepan Kasal <kasal@ucw.cz>
2718 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

2729 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
2730 mistaken comment: the path has to be relative; do not use
2731 the path at runtime.
2733 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2735 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

2739 for both changes.
2740 * doc/autoconf.texi (Setting Output Variables): Fix example to
2741 not show `--silent' being passed to a `configure' re-run.
2743 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
2745 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
2746 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
2747 for the existence of the directory at configure-time. That's
2748 too late, anyway. Problem reported by Stefan Seefeld.
2750 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
2751 7.1.4 /usr/bin/posix/sh described by Tim Rice in
2752 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
2754 2006-09-11 Stepan Kasal <kasal@ucw.cz>
2756 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
2757 works with GNU M4 1.4.3 again; make the normalized form
2758 match the current m4 message; fix the description.
2759 * test/tools.at (autom4te cache): Adapt to the change.
2761 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
2763 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
2764 to catch glibc bug 2821
2765 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
2767 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
2768 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
2769 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
2770 assume C89.
2772 2006-09-08 Stepan Kasal <kasal@ucw.cz>
2774 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

2792 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
2793 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
2794 accept files with extension `.f'. For consistency, also prefer
2795 xlf over f77.
2796 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
2797 from last patch.
2799 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>

2814 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
2816 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
2817 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
2818 except the first two arguments are reversed.
2819 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
2820 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
2821 caches nor outputs a diagnostic. Suggested by Bruno Haible.
2822 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
2823 equivalent to the old AC_COMPUTE_INT.
2824 (AC_COMPUTE_INT): No longer caches or reports. New signature.
2825 All uses changed to AC_CACHE_CHECK_INT.

2831 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
2832 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
2833 programs should use their Gnulib counterparts.
2834 * doc/autoconf.texi (Particular Functions): Likewise.
2835 (Macro Names, testsuite Invocation): Replace uses of these
2836 obsolete macros with uses of non-obsolete macros.

2860 simplify the code.
2862 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
2864 Fix Lex library problem reported to us by Julio Garvia.
2865 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
2866 for the default, which the user can override.
2867 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
2868 deal with LEXLIB.
2869 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
2870 didn't work if some values were cached but not others. Test for
2871 broken lex libraries like native ia64-hp-hpux11.22; see
2872 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
2873 work around the problem by preferring an empty LEXLIB to -lfl or
2874 -ll. Let the user set LEXLIB='' to indicate no library needed.
2876 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
2877 * README: Likewise.

2979 * doc/autoconf.texi (Particular Programs): Mention that
2980 @INSTALL@ and @MKDIR_P@ may vary for different output files.
2981 Reported by Alexandre Duret-Lutz.
2983 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
2985 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore

2987 Bill Northcott in
2988 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.

3003 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
3004 * doc/autoconf.texi (Header Templates, Default Includes):

3019 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
3020 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
3021 this.
3023 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
3025 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
3026 problems with arg script text that doesn't end in newline, and
3027 with '-e a...'. Problems reported by Ralf Wildenhues.
3029 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
3031 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

3041 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
3042 --help' should mention that `--version' outputs configuration
3043 settings. Report by Bruno Haible.
3045 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
3047 Fix test suite failures reported by Pierre in

3063 less skeptical about "volatile", after discussion with
3064 Bruno Haible on bug-gnulib.
3065 (Limitations of Usual Tools): Warn about sed stripping
3066 leading white space from text. From Bruno Haible.
3068 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
3070 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
3071 compiler complains about it, even if things works after the
3072 complaint. Problem reported by Peter O'Gorman.
3074 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
3075 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
3076 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
3078 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
3080 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

3088 to match M4 1.4.5.
3090 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3092 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
3093 under AC_C_VOLATILE.
3094 (Volatile Objects): Be a little less skeptical about what
3095 "volatile" means. Derived from thoughts by Ben Pfaff in
3096 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
3098 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3100 * doc/autoconf.texi: Fix some typos.
3102 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3104 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3105 more globally, since the 2006-06-30 patch didn't suffice. Problem
3106 reported by Keith Marshall. Also, don't bother with builddir2,
3107 since it shouldn't be needed any more.
3109 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
3111 * doc/autoconf.texi (Generic compiler characteristics):
3112 Document AC_COMPUTE_INT. Fix wrong statements on Default

3126 * NEWS: Document previous change.
3128 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
3130 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
3131 Require that long long int be at least 64 bits wide. C99 requires
3132 this and enough programs depend on it so we should check for it.
3133 Bruno Haible reports in
3134 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
3135 that long long int is 32 bits wide with some nonstandard compilers.
3136 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
3138 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
3140 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3141 to a nonexistent file, so that we don't have to worry about
3142 a local site configuration that doesn't use /usr/local.
3143 Problem reported by Keith Marshall in
3144 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
3146 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
3148 * doc/autoconf.texi: Be more consistent about using @acronym with
3149 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
3150 quite right (it talked about "OSF/Tru64", even though the
3151 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
3152 and it even mentioned "OSF 4"!) and at this point there's little
3153 reason to talk about OSF any more, since it died in 1994.
3154 (Specific Compiler Characteristics): Simplify example of
3155 negative-size array.
3156 (File Descriptors): Reorder to make the text flow better.
3157 Remove joke about "appreciate the various levels"; I didn't get it.
3158 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
3159 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
3160 (File Descriptors, Limitations of Usual Tools):
3161 Tone down the advice against renaming or removing open files.
3162 (Limitations of Usual Tools): Add a new section, on 'rm'.
3164 2006-06-26 Stepan Kasal <kasal@ucw.cz>
3166 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
3167 -lXt in LIBS, idea from Karsten Hopp; this was due since
3168 this change:
3170 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3171 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3172 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3173 (which belong to Xt, not X itself). See Debian bug 327655.
3175 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3177 * configure.ac (AC_INIT): Bump to 2.60a.

3186 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3188 * config/texinfo.tex: Sync from upstream.
3190 * bin/autom4te.in (handle_traces): Transform the `@S|@'
3191 quadrigraph correctly in traces.
3193 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
3194 Fix typos.
3196 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
3197 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
3198 not defined.
3199 * doc/autoconf.texi (Changed Directory Variables): New node,
3200 to document the whole `datarootdir' business a bit better.
3201 * NEWS: Update.
3202 * tests/torture.at (datarootdir workaround): Extend test.
3203 Prompted by report by Alexandre Julliard.
3205 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
3207 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility

3209 fix reported by Larry Jones.
3211 2006-06-22 Alexandre Julliard <julliard@winehq.org>
3213 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
3214 about literal '${datarootdir}' if a definition is found in the
3215 output file.
3217 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
3219 * NEWS: Use "M4" rather than "m4" when appropriate.
3220 Problem reported by Eric Blake.
3221 * doc/autoconf.texi: Likewise.
3222 Use @acronym around BSD, GCC, and GNU when appropriate.
3223 (Why GNU M4): Renamed from "Why GNU m4".
3224 (Redefined M4 Macros): Mention that Posix
3225 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
3226 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
3227 to int.
3229 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3231 * bin/autom4te.in (handle_output): Do not forbid the empty
3232 pattern.
3233 * tests/tools.at (autoconf: the empty token): New test.
3235 2006-06-20 Stepan Kasal <kasal@ucw.cz>
3237 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
3238 calls, so that we do not care whether they are LIFO or FIFO;
3239 in the m4_wrap, do not check which diversion is the topmost
3240 one, just check that the stack is balanced at the end.
3241 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
3242 base diversion forever--pop the previous diversion before
3243 opening the new one; consequently, remove the m4_wrap call.
3244 * lib/autotest/general.m4 (AT_INIT): Likewise.
3245 * tests/m4sugar.at: Do not use
3246 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
3248 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
3249 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3251 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
3252 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
3253 Rework example of m4wrap token-pasting trouble so that it doesn't
3254 care whether it's LIFO or FIFO.
3255 Fix some "contrary to"s that are awkward in English.
3257 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3259 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
3260 to `yes' instead of `int$1_t' if the type is found, for more
3261 consistent configure output (where $1 is the number of bits).
3262 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
3263 Suggested by Bruno Haible.
3265 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
3266 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
3267 with system headers. Report by Bruno Haible.
3269 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3271 * config/config.guess, config/config.sub: Sync from upstream.
3273 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
3274 in order to avoid picking up an older installed frozen m4sh.m4f.
3275 Besides an outdated shell startup, this could have been created
3276 by an earlier M4 version with incompatible frozen file format.
3278 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
3280 * README: Recommend m4 1.4.4 instead of 1.4.3..
3281 * doc/autoconf.texi: Likewise.
3282 (Special Chars in Names): Say that $(.FOO) is portable, as
3283 suggested by Stepan Kasal.
3284 (Installation Directory Variables, Build Directories):
3285 (Automatic Remaking, Subdirectories, Fortran Compiler):
3286 (Making testsuite Scripts, Defining Directories):
3287 Quote variable usages better.
3288 (Making testsuite Scripts): Add clean-local rule to makefile
3289 snippet, by Eric Blake.
3290 (Installation Directory Variables): Fix table item font.
3291 Reword slightly to clarify. Generalize advice about
3292 not using special characters to include all file-related
3293 vars, not just VPATH.
3294 (Special Chars in Variables): Warn about special characters in
3295 $(srcdir) too.
3296 (Assignments): Clarify default-value example as suggested by
3297 Ralf Wildenhues in
3298 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
3299 (Special Shell Variables): Note leading ./ or ../, as suggested
3300 by Eric Blake.
3301 (Limitations of Builtins): Under cd, warn about CDPATH.
3302 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
3303 Ralf Wildenhues.
3305 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3307 * doc/autoconf.texi (Configuration Actions): Remove duplicate
3308 `@var', for texi2html.
3309 (Systemology): Some more word wrapping, for DVI output.
3310 (autom4te Invocation): The short option for `--melt' is `-M',
3311 not `-m'.
3313 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
3315 * doc/autoconf.texi: More formatting and English tweaks,
3316 many suggested by Ralf Wildenhues.
3317 Reword to avoid "@code{...}'s" and the like, since it's ugly
3318 with Emacs info mode. discontents -> woes.
3319 Put a few "will"s back. time stamp -> timestamp.
3320 side-effect -> side effect.
3322 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
3324 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
3325 Warn about $@ not persisting. Problem reported by Julien Danjou in
3326 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
3327 (Special Chars in Names): Renamed from Leading _ in Macro Names.
3328 Mention other special chars, too.
3330 2006-06-14 Eric Blake <ebb9@byu.net>
3332 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
3334 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
3336 * doc/autoconf.texi: Some systematic minor improvements, as
3337 follows. Use "makefile" when talking about makefiles
3338 generally (which might be named "makefile" or "Makefile" or even
3339 "foo.mk"), "Makefile" when talking about a specific makefile
3340 called "Makefile". This unclutters the text from weird quotes
3341 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
3342 values" rather than "@var{foo}s" and similar constructs containing
3343 "}s". Use "Make rules" rather than "Makefile rules". Minor
3344 English-language improvements. Change the prefix "sub-" to "sub"
3345 and "re-" to "re".
3346 Put blank lines around examples more consistently.
3347 Avoid "rather" and "very" as intensifiers.
3348 Avoid "will" as an auxiliary.
3349 (Limitations of Make): Split this node into....
3350 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
3351 (Leading _ in Macro Names, Backslash-Newline-Newline):
3352 (Backslash-Newline Comments, Long Lines in Makefiles):
3353 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
3354 (obj/ and Make, make -k Status, VPATH and Make):
3355 (VPATH and Double-colon, $< in Explicit Rules):
3356 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
3357 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
3358 New nodes, resulting from splitup of Limitations of Make.
3359 All cross-references changed. Raise the top node from
3360 a section to a chapter, and all subnodes accordingly.
3361 Redo the introductory wording to match the new organization.
3362 (Installation Directory Variables): Use an example that is
3363 closer to what Autoconf actually does. Mention that VPATH's
3364 value should not contain metacharacters or white space.
3365 (Fortran Compiler): Fix a VPATH bug in an example.
3366 (Leading _ in Macro Names): Mention that this problem is no longer
3367 of practical concern.
3368 (VPATH and Make): Reword the advice to make it clearer
3369 that Autoconf and Automake support VPATH in non-GNU make, but
3370 many packages have bugs in this area.
3371 ($< in Explicit Rules): Refer to Build Directories rather
3372 than using a (non-VPATH-safe) example.
3373 (Automatic Rule Rewriting): Mention the sort of disaster that
3374 can ensue with Solaris-style rule rewriting with VPATH.
3376 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3378 * doc/install.texi (Compilers and Options): Weaken the
3379 suggestion to use GNU make for VPATH builds.
3381 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
3382 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
3384 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
3385 in regular expression.
3387 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3389 * doc/autoconf.texi (Installation Directory Variables):
3390 Drop extra @samp from `@table @samp' item.
3391 (Limitations of Usual Tools): Comment fix.
3392 Do not nest @samp just to point to other table items.
3393 (Writing testsuite.at) <AT_CHECK>: The second argument to
3394 `@dvar' is already @samp'ed.
3395 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
3396 do not use @var in the second argument.
3398 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
3400 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
3401 $as_shell.exe too. Problem reported by Andreas Buening in
3402 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
3404 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3406 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
3407 `unused variable' compiler warning, for `-Wall -Werror'.
3408 Reported by Jaap Haitsma in
3409 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
3411 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
3413 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
3414 case the compiler dumps core. Problem reported for
3415 OpenServer 5.0.7 by Tim Rice in
3416 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
3417 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3418 Likewise.
3420 2006-06-06 Tim Rice <tim@multitalents.net>.
3422 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
3423 "ERROR" only shows up in "make check" output if there is an
3424 error.
3426 2006-06-06 Eric Blake <ebb9@byu.net>
3428 * tests/tools.at (automatically allowed tokens): Fix typo.
3430 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3432 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
3434 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
3435 typically overflows on x86 CPUs, even though the C standard
3436 requires otherwise.
3438 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3440 * configure.ac (AC_INIT): Bump to 2.59e.
3441 * NEWS: Update.
3443 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3445 Version 2.59d.
3447 * config/texinfo.tex: Sync from upstream.
3449 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
3450 seen, invoke libtoolize with `--ltdl' argument.
3451 * lib/autom4te.in (Autoreconf-preselections): Adjust.
3452 * NEWS: Update.
3453 Suggested by Eric Blake.
3455 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3457 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
3458 reported by Ralf Wildenhues.
3459 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
3461 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3463 * THANKS: Update.
3465 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3467 * doc/autoconf.texi: Modernize some of the references to Solaris.
3469 2006-06-05 Stepan Kasal <kasal@ucw.cz>
3471 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
3472 message issued by AC_REQUIRE.
3473 * tests/m4sugar.at: Check m4_require's error message.
3474 * tests/base.at: Check AC_REQUIRE's error message.
3475 * tests/local.at (AT_CHECK_M4): New macro, almost identical
3476 to...
3477 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
3478 AT_CHECK_M4.
3479 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
3480 `expout' as the last parameter.
3481 * tests/tools.at: Adapt to the above change.
3483 2006-06-04 Stepan Kasal <kasal@ucw.cz>
3485 * doc/autoconf.texi (Limitations of Usual Tools): Correct
3486 information about race-free implementations of mkdir.
3488 2006-06-04 Eric Blake <ebb9@byu.net>
3490 * bin/autoreconf.in (help): Document M4 environment variable.
3491 * bin/autoconf.as (Usage): Likewise.
3492 * bin/autom4te.in (help): Likewise.
3493 * doc/autoconf.texi (autom4te Invocation): Likewise.
3495 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
3497 * NEWS: GNU make now recommended for VPATH builds.
3498 Mention that some macros are now documented to be obsolescent.
3499 * doc/autoconf.texi:
3500 Prefer "current" to "modern" to describe
3501 currently-used (albeit perhaps old-fashioned) hosts.
3502 Mention which ancient features no longer need to be worried about.
3503 setgid -> set-group-ID
3504 setuid -> set-user-ID (these are the Posix terms)
3505 Fix some misuses of "only".
3506 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
3507 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
3508 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
3509 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
3510 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
3511 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
3512 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
3513 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
3514 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
3515 Mention that these macros are obsolescent.
3516 (Installation Directory Variables): shall -> should
3517 (File Descriptors): Mention that 0, 1, 2 might get reopened.
3518 Mention that it's now safe to use 3 and 4.
3519 (Limitations of Usual Tools): cp -r is now specified by Posix.
3520 Omit longwinded and obsolescent discussion of cp -f.
3521 Modernize discussion of expr, ls.
3522 (Limitations of Make): Modernize discussion of VPATH builds.
3523 Mention $? as a workaround in some cases.
3524 * doc/install.texi (Basic Installation):
3525 Mention "./configure; make; make install" first. Be more
3526 specific about why this file is generic. Remove unnecessary
3527 parens. Remove misleading "only". Remove obsolete advice
3528 about csh. Don't say "configure" takes awhile; say it
3529 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
3530 and CC=c99 rather than CC=c89, as these are blessed by current
3531 Posix. Recommend GNU make if doing a VPATH build.
3533 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
3535 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
3536 examples involving shell prompts.
3538 2006-06-02 Stepan Kasal <kasal@ucw.cz>
3539 and Paul Eggert <eggert@cs.ucla.edu>
3541 * doc/autoconf.texi (Here-Documents): Add details about the
3542 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
3543 use "here-documents" instead of "here documents".
3545 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3547 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
3549 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
3551 * doc/autoconf.texi (File System Conventions): Warn about ":"
3552 anywhere in directory names.
3554 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
3556 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
3557 about quoting the case statement, just in case.
3558 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
3559 was fixed in ksh93g; reported by Ralf Wildenhues.
3561 2006-05-31 Stepan Kasal <kasal@ucw.cz>
3563 * doc/autoconf.texi (System Services): Do not document
3564 overriding EXEEXT via ac_cv_exeext=ext.
3565 (Particular Programs) <AC_PROG_MKDIR_P>:
3566 Document that ${MKDIR_P} understands --.
3567 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
3568 comment.
3570 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3572 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
3573 argument with leading hyphen. Problem reported by Paul Eggert.
3575 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3577 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
3578 about quoting ac_try: quote all of it, if any of it seems suspicious.
3579 This means we don't have to worry about ${ or sed any more.
3580 Also, double-quote the case statement, to work around misuses via
3581 underquoting as reported by Ralf Wildenhues in
3582 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
3583 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
3584 undocumented and dangerous macro.
3585 Problem reported by Ralf Wildenhues in
3586 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
3588 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3590 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
3591 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
3592 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
3594 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3596 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
3597 since evidently some packages rely on the old, broken behavior.
3598 Problem reported by Ralf Wildenhues in
3599 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
3600 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
3601 pre-2006-05-26 definitions, but leave in the comments that
3602 these macros are dangerous and should not be used.
3603 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
3604 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
3605 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
3606 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
3607 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
3609 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
3611 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
3612 the use of 'tr', since this is our only use of 'tr'.
3614 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3615 and Paul Eggert <eggert@cs.ucla.edu>
3617 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
3618 Don't assume 'grep' works on long lines, since AIX grep doesn't.
3620 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3622 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
3623 the output file in the `${datarootdir}' test.
3625 2005-05-28 Stepan Kasal <kasal@ucw.cz>
3626 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3628 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
3629 mention of `datarootdir' in the input file(s), but literal
3630 `${datarootdir}' in the output file, and we haven't warned yet,
3631 then warn as well: the user may have (erroneously) used
3632 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
3633 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
3634 * tests/torture.at (datarootdir workaround): Extend this test.
3635 * NEWS: Update.
3637 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3638 and Paul Eggert <eggert@cs.ucla.edu>
3640 * doc/autoconf.texi (autoheader Invocation): The first argument to
3641 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
3642 alternatives and clear up the language a bit.
3644 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
3646 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
3647 ac_config_guess, ac_config_sub, ac_configure.
3648 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3649 Fix typo that prevented an unnecessary space from being removed.
3650 Problems reported by Ralf Wildenhues in:
3651 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
3653 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
3655 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
3656 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
3657 Don't use the term "thread-safe" to talk about mkdir race
3658 conditions, since the problem is more a process than a thread
3659 issue. Problem reported by Stepan Kasal in:
3660 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
3661 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
3662 the test for 'install' more closely. Look at MKDIR_P first.
3663 Look in the PATH, and at /opt/sfw/bin.
3664 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
3665 Don't bother to try mkdir -p, since we already check mkdir --version;
3666 just look at the version number. (There's no easy way to check
3667 for race-free implementations.)
3668 * tests/tools.at (autoconf: subdirectories): Adjust to above
3669 changes, since MKDIR_P now might end in "/mkdir -p".
3671 * doc/autoconf.texi (autoheader Invocation): Mention that the
3672 first arg of AC_DEFINE_UNQUOTED must be a literal.
3673 Problem reported by Ben Pfaff in
3674 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
3676 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
3677 * doc/autoconf.texi (Special Chars in Variables): New section.
3678 (Preset Output Variables): Warn about special chars in CPPFLAGS.
3679 (Installation Directory Variables): Quote $(datadir) better.
3680 (Limitations of Builtins): Describe some of eval's trickiness.
3682 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
3683 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
3684 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
3685 in front of every arg, not just trailing args. Quote apostrophes.
3686 (_AC_EVAL_ECHO): New macro.
3687 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
3688 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
3689 removed.
3690 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
3691 exposed by quoting of eval argument. Put the command on line line
3692 so it logs better.
3693 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
3694 (_AC_PATH_X, AC_PATH_X): Quote more safely.
3695 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
3696 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
3697 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
3698 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
3699 Use eval more safely.
3700 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
3701 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
3702 to be replaced.
3703 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
3704 lines, exposed by quoting of eval argument.
3706 2006-05-26 Stepan Kasal <kasal@ucw.cz>
3707 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3709 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
3710 initialization of `ac_cv_exeext', do not override it if it was
3711 already set, unless it was set to `no', for compatibility with
3712 Autoconf-2.13, and comment this.
3713 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
3714 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
3715 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
3716 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
3717 Document that this test may be overridden by setting
3718 `ac_cv_exeext'.
3720 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3722 Revert these two patches:
3724 2006-04-06 Eric Blake <ebb9@byu.net>
3725 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3726 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3727 2006-04-01.
3729 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3730 Clean up _AC_COMPILER_EXEEXT* macros.
3731 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3732 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3733 ac_file to the name of the default output file and call
3734 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3735 initial `rm' of the candidate files...
3736 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3737 the same list in subsequent `rm' calls, and for the temporary
3738 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3739 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3740 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3741 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3742 no longer needed) by libtool. Make it a cache check.
3743 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3744 copied here by mistake.
3745 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3746 _AC_COMPILER_EXEEXT.
3747 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
3748 _AC_COMPILER_OBJEXT directly.
3749 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3751 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3753 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
3754 Fix description of how the buggy `sed' works.
3756 2006-05-25 Noah Misch <noah@cs.caltech.edu>
3758 Sync from Automake:
3760 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
3761 ENOLCK. Only mention `make -j' when applicable. Only raise
3762 fatal errors when `make -j' is involved. Improve error message.
3764 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3766 * doc/autoconf.texi (Here-Documents): We now know more about
3767 the variable expansion in here documents bug.
3768 Thanks to Tim Rice and Stepan Kasal.
3770 * doc/autoconf.texi (Making testsuite Scripts): Add an example
3771 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
3773 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3775 * tests/autotest.at (Multiline command from M4 expansion):
3776 No failure to be expected if the shell quotes newlines in
3777 commands in the `set -x' output. Report by Tim Rice.
3778 * THANKS: Update.
3780 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3782 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
3783 expansion in the here-documents used by config.status, as that
3784 runs afoul of the Korn shell version M-12/28/93d bug described in
3785 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
3786 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
3787 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
3789 2006-05-23 Jim Meyering <jim@meyering.net>
3791 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
3792 Fix typo introduced with 2006-04-02 change. It reversed the sense
3793 of the test.
3795 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3797 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
3798 ac_dB slightly, to save bytes in the script.
3799 Max out at 50 lines, rather than 96; this is more likely
3800 (though not guaranteed) to avoid obscure 'sed' failures.
3802 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3804 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
3805 `tr -d -' as bad option argument. Work around this by deleting
3806 an unrelated character.
3807 Report by Tim Rice <tim@multitalents.net>.
3809 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
3810 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3811 Stepan Kasal <kasal@ucw.cz>
3813 * doc/autoconf.texi (Particular Programs): Do not promise that
3814 we always prefer the GNU version of the program, and that we
3815 search according to PATH; both rules can have exceptions.
3816 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
3817 AC_PROG_SED. Move descriptions of limitations
3818 to the Limitations of Usual Tools section.
3819 (Limitations of Usual Tools) <sed>: Mention script length
3820 limitations with Solaris /usr/ucb/sed.
3821 <grep>: Fix wording for empty alternative. Mention that -c and
3822 -l should not be combined, and that -E and -F should not be
3823 combined.
3825 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3826 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3828 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
3829 limits in Solaris 8 /usr/ucb/sed by testing a long script.
3831 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3833 * doc/autoconf.texi (Defining Symbols): Literal parameter of
3834 AC_DEFINE is now passed to m4_pattern_allow.
3835 * NEWS: Mention that; likewise for AC_SUBST.
3836 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
3837 the parameter to m4_pattern_allow.
3838 * tests/tools.at: Add a check for that.
3840 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3842 * lib/autoconf/status.m4: Fix typos.
3844 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3846 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
3847 only the files that this macro generates.
3849 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3851 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
3852 the HP-UX sed limitation of 99 commands, labels do not count.
3853 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
3854 in the comment.
3855 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
3857 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3859 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3860 Import the following fix from coreutils:
3862 2006-01-13 Jim Meyering <jim@meyering.net>
3864 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
3865 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
3866 not double-quote uses of that variable, to accommodate the rare
3867 case in which getmntent is available in none of the libraries
3868 checked. This happens at least on FreeBSD 5.0.
3870 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
3872 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
3873 ac_config_guess, ac_config_sub, and ac_configure, since evidently
3874 some other programs unwisely rely on these undocumented vars.
3875 But put in warning comments about them.
3876 Problem reported by Ralf Wildenhues in
3877 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
3878 * NEWS: Document that these variables are intended to go away.
3880 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3882 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
3883 and set the language to C++ (analogous to the equivalent Fortran
3884 tests).
3886 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
3887 * doc/autoconf.texi (C++ Compiler): Document it.
3888 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
3889 * NEWS: Update.
3891 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
3893 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
3894 that caused config.status to generate 100-command sed scripts; the
3895 portable limit is 99.
3897 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3899 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
3900 variable `ac_d' instead of `d' to avoid infringing namespace.
3901 Report by Ralf Menzel.
3903 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
3905 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
3906 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
3907 * tests/tools.at (autoconf: subdirectories): New test, taken from
3908 the corresponding problem report by Ralf Wildenhues in:
3909 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
3911 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
3912 Quote some uses of shell variables if they might suffer unexpected
3913 globbing. This doesn't fix all instances of quoting problems that
3914 I found, just the easy ones that look safe.
3915 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
3916 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
3917 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
3918 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
3919 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
3920 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
3921 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
3922 Likewise.
3923 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
3924 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
3926 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3928 * bin/autoreconf.in ($help): Reword according to the manual.
3929 Suggested by Olly Betts.
3931 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
3932 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3934 * bin/autoreconf.in: Pass the directory argument to
3935 `require_configure_ac'. Fix comment.
3936 * tests/torture.at (Configuring subdirectories): Expose this.
3937 Reported by Olly Betts.
3939 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3941 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
3942 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
3943 Automake as follows:
3945 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
3946 `$configure_in' instead of `configure.in', to preserve
3947 directory component.
3949 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3951 * config/config.guess, config/config.sub, config/texinfo.tex,
3952 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
3954 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
3956 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
3957 test for C99 conformance; (bool) 0.5 is an integer constant
3958 expression, but (bool) -0.5 is not. Problem reported by Fedor
3959 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
3961 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
3963 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
3964 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
3965 Warn about obsolete install-sh files. Remove stray sentence
3966 fragment and fix cross reference.
3967 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
3968 install -d; this undoes the 2006-05-10 change.
3969 (MKDIR_P): Mark with AN_MAKEVAR.
3970 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
3971 that we don't require $INSTALL to be thread-safe. Move comments
3972 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
3973 of AC_PROG_INSTALL. Output a message saying that we're checking
3974 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
3975 MKDIR_P instead of AC_SUBST.
3976 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
3977 Special magic for MKDIR_P, too.
3978 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
3979 a dnl.
3980 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
3982 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
3984 Sync from Automake, as follows:
3986 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3987 * config/install-sh: Initialize IFS, so field splitting isn't
3988 turned off later.
3989 * config/mkinstalldirs: Likewise.
3990 * config/missing: Remove superfluous quotes. Replace all uses of
3991 `[' by `test', for consistency, and for..
3992 * config/missing (sed_minuso, sed_output): New variables.
3993 (autom4te, help2man, makeinfo): Use them. Unifies detection of
3994 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
3995 Fixes `missing' to detect `--output' for help2man. Fixes
3996 PR automake/483. Report by Dennis J. Linse.
3997 (autom4te): Document in `missing --help'.
3999 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4001 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
4002 * config/install-sh: Don't use 'path' to talk about file names,
4003 as per GNU coding standards. Close a race condition reported by Ralf
4004 Wildenhues and Stepan Kasal. There is still a race condition
4005 on hosts that predate Posix 1003.1-1992, but we can't help this.
4006 Don't mishandle weird characters like space on pre-Posix hosts.
4007 Invoke mkdir at most once per dir arg on pre-Posix hosts.
4008 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
4009 AC_PROG_MKDIR_P from AS_MKDIR_P.
4010 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
4011 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
4012 earlier editions are not (including Automake 1.8.3).
4013 Do not suggest mkinstalldirs for thread-safety.
4014 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
4015 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
4016 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
4017 presence of special characters and race conditions.
4018 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
4019 in Autoconf's name space.
4021 2006-05-10 Bruno Haible <bruno@clisp.org>
4022 and Paul Eggert <eggert@cs.ucla.edu>
4024 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
4025 from Automake with minor changes.
4026 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
4028 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4030 * config/install-sh: Update to Automake CVS version, as follows:
4031 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4032 * lib/install-sh: Simplify the expr implementation of dirname.
4033 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
4034 * lib/install-sh: Handle --, and diagnose unknown options.
4036 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4038 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
4039 `./autom4te' to create `./testsuite', since the `all' target
4040 will ensure its presence, but `installcheck' should not create
4041 the uninstalled wrappers.
4043 * tests/torture.at (Unusual Automake input files): Skip if we
4044 detect automake < 1.8.
4046 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4048 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
4049 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
4050 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
4051 * NEWS: Update.
4053 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4055 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
4056 munge (multiple) white space and other oddities.
4057 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
4058 single quotes in variable assignment.
4059 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
4060 and similar failures by adding multiple spaces, tabs, and other
4061 special characters.
4062 Report and different test suggested by Francesco Romani
4063 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
4065 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
4066 single quotes, we only need to search for single quotes; this
4067 both simplifies the search pattern, and makes us less
4068 susceptible to `echo' variations for arguments not containing
4069 single quotes.
4070 (_AC_ARG_VAR_VALIDATE): Likewise.
4072 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4074 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
4075 `$*' and IFS concatenation issue with traditional shells and
4076 bash-2.04. Report by Seanster@Seanster.com.
4078 2006-05-03 Bruno Haible <bruno@clisp.org>
4080 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
4081 precisely which Mac OS X versions have the od problem.
4083 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4085 * doc/autoconf.texi: Use @option systematically.
4087 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4088 and Bruno Haible <bruno@clisp.org>
4090 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
4091 about 'od'.
4092 (Integer Overflow): Mention the special case of integer division
4093 overflow.
4095 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4097 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
4098 traditional shells like the Solaris one that do not use the
4099 first IFS character for assembling `$*'.
4100 Prompted by a related report from autoconf_bug@nro.ca.
4102 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
4103 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4105 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
4106 Mention more problems with the -e option.
4108 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4110 * NEWS: Typo.
4111 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
4113 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
4114 in URLs to improve DVI formatted output (requires texinfo 4.6).
4115 (System Services, Systemology, Shellology): Likewise.
4116 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
4117 output.
4119 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
4120 continuous text.
4121 (Runtime): Fix macro argument names to match description:
4122 `action-if-found' -> `action-if-true' and similarly.
4123 (Obsolete Macros): Likewise.
4124 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
4125 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
4126 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
4128 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4130 * doc/autoconf.texi (Limitations of Make): Clean up markup.
4132 * ChangeLog: Typo.
4133 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
4134 DVI output.
4136 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4138 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
4139 /bin/sh set unsorted output.
4140 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
4141 * tests/local.at: Likewise.
4143 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
4145 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
4146 (Integer Overflow, Null Pointers, Buffer Overruns):
4147 (Floating Point Portability, Exiting Portably): New sections.
4148 (Writing Test Programs): Fix some langauge. Recommend exiting
4149 with status 1, not merely nonzero. Clarify exit declaration.
4150 (Run Time): Move C exit status stuff to new Exiting Portably section.
4151 (Systemology): Mention Posix and levenez. Update v7 reference.
4152 (Portable Shell): Mention the Posix shell.
4154 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4156 * bin/autoconf.as (me): Replace by as_me.
4158 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
4160 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
4161 since as_me isn't set yet.
4163 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4165 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
4166 a few minor bugs in this area.
4168 * doc/autoconf.texi (Programming in M4sh): Comment out the
4169 documentation of AS_BASENAME, for now.
4170 (Shell Substitutions): Do not use AS_DIRNAME in an example.
4171 (Limitations of Builtins) <basename>: Do not refer to
4172 AS_BASENAME.
4173 * bin/autoconf.as (me): Don't use AS_BASENAME.
4174 (dir): Remove the unused variable.
4175 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
4176 AS_DETECT_REQUIRED. All uses changed.
4177 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
4178 All uses changed.
4179 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
4180 (AS_BASENAME): Use "basename --" to protect against leading "-".
4181 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
4182 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
4183 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
4184 (_AS_DIRNAME_PREPARE): Likewise.
4185 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
4186 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
4187 (AS_DIRNAME): Use "dirname --".
4189 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4191 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
4192 of "run time" and "run-time" changed to "runtime", for consistency.
4193 * lib/autoconf/fortran.m4: Likewise (in comment).
4194 * lib/autoconf/functions.m4: Likewise.
4195 * lib/autoconf/general.m4: Likewise.
4196 * lib/autoconf/headers.m4: Likewise.
4198 * doc/autoconf.texi (Run Time): Document the exit status situation
4199 with more accuracy and detail.
4201 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4203 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
4204 Archive is not officially `GNU' any more. Update URL.
4205 (Defining Directories): Likewise
4206 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
4208 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4210 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
4211 newline from the `trap' code to finish `config.log'; the NetBSD
4212 /bin/sh resets the exit status after an empty command, as
4213 documented in doc/autoconf.texi.
4214 Reported by Dalibor Topic <robilad@kaffe.org>.
4216 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
4218 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
4219 Suggested by Bruno Haible.
4221 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
4223 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
4224 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
4225 Instead, just list the shells that we know work.
4226 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
4227 changed. Be more cautious about the _cv_ variable.
4228 * tests/tools.at (Syntax of the shell scripts): Check the
4229 _cv_ variable once, at first, to avoid an internal autoconf error
4230 when sh -n does not work.
4232 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4234 * lib/Autom4te/FileUtils.pm: Sync from Automake.
4236 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
4238 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
4239 use ">&-" since we're only 99.999% sure that this is portable,
4240 and since the MinGW bug is fixed in a different way.
4241 * lib/autotest/general.m4 (AT_INIT): Likewise.
4243 2006-04-16 Stepan Kasal <kasal@ucw.cz>
4245 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
4246 before opening config.log, to avoid hitting a bug on MinGW.
4248 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
4250 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
4251 AS_MESSAGE_LOG_FD before reopening it onto the log file.
4252 This works around a MinGW bug reported by Eric Paire.
4253 Make sure that all writes to the log file append to it,
4254 rather than possibly losing data.
4255 * lib/autotest/general.m4 (AT_INIT): Likewise.
4257 2006-04-14 Stepan Kasal <kasal@ucw.cz>
4259 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
4260 description.
4262 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4264 * NEWS: Update.
4266 * configure.ac (AC_INIT): Bump to 2.59d.
4268 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4270 Version 2.59c.
4272 * Makefile.maint (news-date-check): Do not require a leading `*'
4273 before the release date in NEWS.
4275 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4276 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4278 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
4279 the instantiated file do not contain the string 'datarootdir'
4280 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
4281 @mandir@, replace the reference '${datarootdir}' by the value.
4282 * tests/torture.at (datarootdir workaround): New test.
4283 * NEWS: Advertise this temporary fixup.
4284 Based on a patch by Bruno Haible, reported and analyzed by
4285 Paul Eggert and Noah Misch.
4287 2006-04-12 Eric Blake <ebb9@byu.net>
4289 * tests/autotest.at (Debugging a failed test): Fix comment.
4291 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4293 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
4294 all the changes since 2006-04-07.
4296 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4298 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
4299 succeeded, but `ln -s file dir' failed, take care to remove the
4300 leftover target before the next test, to prevent its spurious
4301 failure; also make sure `ln file dir' works before selecting it.
4302 Thanks to Keith Marshall for pointing this out.
4303 * THANKS: Update.
4305 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
4306 assignments in `at_debug_args', so that we put them correctly
4307 in the `run' script.
4308 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
4309 Reported by Eric Blake.
4311 2006-04-11 Eric Blake <ebb9@byu.net>
4313 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
4314 top-level tests after micro-suite has been run. Used in...
4315 (Debugging a successful test, Debugging script and environment),
4316 (Debugging a failed test): ...these new tests. The first of these
4317 is fixed by...
4318 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
4319 macro, split out from...
4320 (AT_INIT): ...here, so that using -d also generates a run script.
4321 Document that -d inhibits top-level logging.
4322 * doc/autoconf.texi (testsuite Invocation): Document that -d only
4323 inhibits top-level logging; debug scripts are created.
4325 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
4326 check.
4327 * tests/autotest.at (Empty test, Empty check): New test to check it.
4329 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
4330 from gcc.
4332 2006-04-10 Stepan Kasal <kasal@ucw.cz>
4334 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
4335 the files if a problem appears. Make the empty *.at files
4336 read-only, too. Proposed by Ralf Wildenhues.
4338 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4340 * config/Makefile.am: Add comment to force updated Makefile.in.
4342 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
4343 space only patch to this file, this patch causes the Makefile.in
4344 files that include freeze.mk to be updated, and thus have a
4345 newer time stamp again, which in turn makes a pristine CVS
4346 checkout have correct time stamps.
4348 * Makefile.maint (cvs-sv): New macro, to be used..
4349 (config.guess-url_prefix, config.sub-url_prefix)
4350 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
4351 point to CVS text checkout of Gnulib files.
4352 (copyright-check): Bump current year.
4353 (announcement): Do not hard-wire `./announce-gen'.
4354 (cvs-update): Propagate failures of `cvs' and `move-if-change'
4355 correctly.
4356 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
4357 `chmod +x'.
4358 (wget_files): Update config.guess, config.sub, texinfo.tex by
4359 `wget-update', now that their URLs work again.
4361 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4363 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
4364 Problem noted by Paul D. Smith.
4366 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4368 * doc/autoconf.texi: Remove unused words from word list.
4369 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
4370 .x-sc_trailing_space: New files.
4372 * doc/standards.texi: Sync from gnulib.
4374 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
4375 `LIBOBJDIR' as experimental.
4377 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
4378 with a target directory; it's internally implemented as `cp'
4379 anyway, but since Autoconf advertises the possibility to use
4380 a target directory when LN_S is `ln -s', we need to find out.
4381 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
4382 analyzed by Keith Marshall <keith.marshall@total.com>.
4384 * THANKS: Update.
4386 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4388 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
4389 confdefs.h as-is. In general, if it has backslash-newline or the
4390 like, then it doesn't work either to sort or to remove empty
4391 lines.
4393 2006-04-09 Stepan Kasal <kasal@ucw.cz>
4395 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
4397 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
4399 * lib/autom4te.in (Automake-preselections): Preselect
4400 _AM_SUBST_NOTMAKE.
4402 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4404 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
4405 apostrophe within a single-quoted string, as this is the usual
4406 tradition and is easier to read than '"'"'. Don't rely on the
4407 shell treating "$/" like '$/'. Use a more-consistent indenting
4408 style for the trap.
4410 2006-04-09 Eric Blake <ebb9@byu.net>
4412 * tests/autotest.at (Backquote command substitution),
4413 (Multiline backquote command substitution): Remove mistaken
4414 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
4415 applied...
4416 (Parenthetical command substitution, Multiline parenthetical
4417 command substitution): here.
4419 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4421 Import macros from gnulib (often changing their name).
4423 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
4424 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
4425 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
4426 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
4427 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
4428 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
4429 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
4430 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
4431 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
4432 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
4433 The manual mentions Gnulib more prominently.
4434 * doc/autoconf.texi (Gnulib): New node.
4435 (Pointers): Add Gnulib URL.
4436 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
4437 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
4438 Gnulib section.
4439 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
4440 suggest a #define rather than a typedef for _Bool, and mention
4441 Gnulib rather than trying to substitute stdbool code.
4442 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
4443 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
4444 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
4445 AC_STRUCT_DIRENT_D_TYPE.
4446 (Particular Types): Mention stdint.h and inttypes.h as standard
4447 headers too.
4448 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
4449 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
4450 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
4451 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
4452 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
4453 (C Compiler): Move AC_C_LONG_DOUBLE to ...
4454 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
4455 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
4456 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
4457 (Coding Style). Don't mention m4_expand_once.
4458 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
4459 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
4460 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
4461 (AC_CHECK_FUNCS): Use it.
4462 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
4463 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
4464 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
4465 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
4466 (AC_HEADER_ASSERT): New macro.
4467 (AC_HEADER_STDBOOL): Don't assume "#error" works.
4468 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
4469 Catch a bug in an HP-UX C compiler.
4470 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
4471 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
4472 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
4473 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
4474 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
4475 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
4476 New macros.
4478 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
4479 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
4481 2006-04-08 Stepan Kasal <kasal@ucw.cz>
4483 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
4484 of the warning introduced by the 2001-08-28 change.
4486 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
4487 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4489 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
4490 variables shall be overriden by the cache.
4491 * tests/torture.at (AC_ARG_VAR): Test also with a first value
4492 that contains braces.
4494 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4496 Revert the patch from 2006-04-01 and only improve
4497 _AS_DETECT_BETTER_SHELL:
4499 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
4500 skip nonexistent directories.
4501 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
4502 only shell candidates which exist.
4503 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
4504 * lib/autotest/general.m4 (AT_INIT): No need to give three
4505 parameters to _AS_PATH_WALK.
4507 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
4508 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4510 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
4511 distinguish m4sugar macros.
4512 * tests/tools.at (autoupdating with aclocal and m4_include):
4513 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
4514 test case by Noah Misch <noah@cs.caltech.edu>.
4516 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4518 Revert my change from 2006-03-17, in other words:
4519 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
4520 and DUALCASE=1.
4521 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
4522 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
4523 it is set.
4525 2006-04-07 Eric Blake <ebb9@byu.net>
4527 * doc/autoconf.texi (Programming in M4sh): Document that
4528 AS_MKDIR_P exits the script on failure.
4529 * lib/autotest/general.m4: Remove redundant AS_ERROR.
4531 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4533 * config/elisp-comp, config/install-sh, config/mdate-sh,
4534 config/missing, config/mkinstalldirs: Sync from Automake.
4536 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
4537 from Automake.
4539 * doc/make-stds.texi: Sync from gnulib.
4541 2006-04-06 Eric Blake <ebb9@byu.net>
4543 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4544 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4545 2006-04-01.
4547 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
4548 Eric Blake <ebb9@byu.net>,
4549 Paul Eggert <eggert@cs.ucla.edu>,
4550 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4552 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
4553 whether `set' quotes correctly: redirect stderr of the tested
4554 `set', and use a subshell, for Ultrix; use `sed' instead of
4555 `grep' for zsh `set' which may write binary output; match only
4556 at the beginning of a line, to avoid false positives.
4557 In order to avoid false positives by unrelated variables with
4558 multiline content, put the dump algorithm in a subshell and
4559 unset all variables containing newlines (except some which are
4560 special to the shell). Warn about cache variables that are
4561 unset.
4563 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4565 * config/config.guess, config/config.sub, config/texinfo.tex:
4566 Sync from upstream.
4568 * tests/mktests.sh: Reword comments.
4570 * tests/mktests.sh: Only skip internal macros starting with
4571 `_AC_' or `__AC_'. Noted by Stepan Kasal.
4572 Update exclusion lists for the test suite to this end:
4573 (AC_ARG_VAR): Do test this now.
4574 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
4575 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
4576 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
4577 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
4579 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
4580 shell issue with double-quoted command substitutions of native
4581 commands.
4582 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
4583 Marshall.

4623 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

4764 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4765 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4766 ac_file to the name of the default output file and call
4767 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4768 initial `rm' of the candidate files...
4769 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4770 the same list in subsequent `rm' calls, and for the temporary
4771 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4772 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4773 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4774 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4775 no longer needed) by libtool. Make it a cache check.
4776 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4777 copied here by mistake.
4778 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4779 _AC_COMPILER_EXEEXT.

4816 subordinate tools.
4817 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
4818 * doc/autoconf.texi (autoreconf Invocation): Document it.
4820 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

4852 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4854 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
4855 switch all of them on and of when necessary. Fixes the bug when
4856 m4sugar macros (e.g., m4_define) were expanded after the first

4906 * bin/autoscan.in: The value of find_configure_ac should be
4907 checked for existence, so we don't barf over a nonexisting
4908 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
4910 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5500 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
5501 ac_pt_* variables.
5503 2005-11-01 Stepan Kasal <kasal@ucw.cz>
5505 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
5506 filesystems.
5508 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5510 * NEWS: Move AH_HEADER mention to right place.
5512 2005-10-27 Stepan Kasal <kasal@ucw.cz>
5514 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
5515 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
5517 2005-10-25 Stepan Kasal <kasal@ucw.cz>
5519 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
5520 conftst2.$ac_objext.
5521 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
5523 2005-10-24 Stepan Kasal <kasal@ucw.cz>
5525 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
5526 conftest.o, to see whether the compiler really obeys; rm the object
5527 file before and after the test and register it with ac_clean_files.
5528 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
5530 2005-10-21 Stepan Kasal <kasal@ucw.cz>
5532 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
5533 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
5534 code so that the most common case requires less forks.
5536 2005-10-20 Stepan Kasal <kasal@ucw.cz>
5538 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
5539 not portable; thanks to Paul Eggert and Alexandre.
5541 * NEWS: Fix an old typo.
5543 2005-10-20 Jim Meyering <jim@meyering.net>
5545 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
5546 the latter'', in two places.
5548 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
5550 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
5551 AC_LANG_PROGRAM, fixing a typo. Don't give details about
5552 the inner workings of AC_LANG_FUNC_LINK_TRY.
5553 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
5554 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
5555 by the function rather than ignoring it.
5556 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
5557 comparing its address. Intel's interprocedural optimization was
5558 outsmarting the old heuristic. Problem reported by
5559 Mikulas Patocka.
5561 2005-10-19 Stepan Kasal <kasal@ucw.cz>
5563 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
5565 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
5567 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

5570 2005-10-04 Stepan Kasal <kasal@ucw.cz>
5572 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
5573 before removing it (chmod -R u+rwx); there are three instances of this.
5575 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5576 Stepan Kasal <kasal@ucw.cz>
5578 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
5579 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
5580 make its content writable before removing it. Remove an errorneous
5581 comment from the end, where the logs of the failed tests are copied
5582 to the main log file.
5584 2005-09-27 Stepan Kasal <kasal@ucw.cz>
5586 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
5587 in case the computer is too quick. Double quote the configure.ac
5588 snippets.
5590 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
5591 problems if the testsuite were running too fast.
5593 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5595 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5596 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5597 (which belong to Xt, not X itself). See Debian bug 327655.
5598 * NEWS: Mention this.
5600 2005-09-07 Stepan Kasal <kasal@ucw.cz>
5602 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
5604 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
5606 * config/move-if-change: Don't output "$2 is unchanged";
5607 suggested by Ben Elliston. Handle weird characters correctly.
5609 2005-09-06 Stepan Kasal <kasal@ucw.cz>
5611 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
5612 calls, so that the final expansion of this macro is shorter.
5613 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
5614 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
5615 the cleanup there. Use AS_VAR_* macros, to be more general.
5616 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
5618 * lib/autoconf/general.m4: Use AS_IF where appropriate.
5620 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
5622 2005-09-01 Stepan Kasal <kasal@ucw.cz>
5624 * doc/autoconf.texi (Configuration Headers): Add an index entry
5625 for AH_HEADER.
5627 2005-08-26 Pavel Roskin <proski@gnu.org>
5629 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
5630 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
5631 running xmkmf.
5633 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
5635 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
5636 The previous patch didn't work, so try a better one.
5638 2005-08-26 Stepan Kasal <kasal@ucw.cz>
5640 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
5641 in the example. Reported by Bruno Haible.
5642 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
5643 "if $undefined_var;" succeeds with my shell.
5645 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
5646 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
5647 but change the m4_divert_text to m4_divert_once.
5649 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
5651 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
5652 Work around bug in Solaris /usr/xpg4/bin/awk.
5653 The bug is present in at least Solaris 8 through 10.
5655 2005-08-24 Stepan Kasal <kasal@ucw.cz>
5657 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
5658 some evil values and relying on the fact that $* concatenates the
5659 parameters by the first character from IFS.
5661 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5662 Stepan Kasal <kasal@ucw.cz>
5664 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
5665 first header appears, define AH_HEADER.
5666 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
5667 Update limitations about when to call AC_CONFIG_HEADERS.
5668 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
5669 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
5670 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
5671 ``Configuration Actions''; fix their index entries.
5673 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
5674 options correctly. Process N-M as M-N if M is smaller than N.
5675 Process ranges correctly so that N-N will run only N.
5676 Sort and uniquify the tests that will be run. If there is more
5677 than one test, reinsert the banners for the tests.
5678 * tests/autotest.at (Keywords): Unmark XFAIL.
5680 2005-08-23 Stepan Kasal <kasal@ucw.cz>
5682 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
5683 before passing the macro name to AH_TEMPLATE.
5685 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
5686 now opens log after option processing; in particular, --version
5687 and --help do not touch config.log.
5689 * Makefile.maint: Revert the change from 2005-08-12.
5691 2005-08-22 Stepan Kasal <kasal@ucw.cz>
5693 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
5694 common code to...

5699 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
5700 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
5701 Language cleanup.
5703 * doc/autoconf.texi (Defining Symbols, Changed Results):
5704 Prepend to LIBS, not append, in examples.
5706 2005-08-16 Stepan Kasal <kasal@ucw.cz>
5708 When building in place, set srcdir="."; suggested by Tim Van Holder.
5710 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
5711 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
5712 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
5713 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
5714 does not mean "no --srcdir option".
5716 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5718 * tests/autoscan.at (autoscan): New file.
5719 * tests/suite.at: Use it.
5720 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
5721 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
5723 * tests/autotest.at (Keywords): Test keywords combinations.
5725 2005-08-12 Stepan Kasal <kasal@ucw.cz>
5727 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
5728 add "2>&1"; gzip 1.2.4 prints help on stderr.
5730 2005-07-27 Stepan Kasal <kasal@ucw.cz>
5732 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
5733 was pushdef'ed twice while popped only once. Push it only once.
5734 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
5736 2005-07-26 Stepan Kasal <kasal@ucw.cz>
5738 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

5743 * Makefile.maint: Update from Bison.
5745 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
5746 "<tab>" in comment, so that the point is understandable.
5748 2005-07-25 Stepan Kasal <kasal@ucw.cz>
5750 Rewrite substantial part of lib/autoconf/status.m4.
5751 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
5752 and CONFIG_COMMANDS are not processed in four separate loops.
5753 Instead, there is one main loop. This alows that the common code
5754 is expanded only once, thus config.status (and configure) is smaller.
5756 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
5757 the AC_LIST_FILES and cousins macros are no longer used.
5759 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
5760 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
5761 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
5762 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
5763 contain the initialization, nor the for loop, nor the associated
5764 commands; all these go to ...
5765 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
5766 _AC_OUTPUT_CONFIG_STATUS.
5767 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
5768 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
5769 (_AC_OUTPUT_FILE): The creation of the sed script ...
5770 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
5771 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
5772 _AC_OUTPUT_MAIN_LOOP.
5773 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
5774 _AC_CONFIG_COMMANDS): Use ...
5775 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
5776 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
5777 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
5778 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
5779 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
5780 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
5781 ... new macros.
5782 (_AC_CONFIG_UNIQUE): Update.
5783 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
5784 Replaced by this ...
5785 (_AC_LIST_TAGS): ... new common macro.
5786 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
5787 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
5788 (_AC_LIST_TAG_COMMANDS): ... new common macro.
5789 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
5790 this didn't belong to the `config commands' section.
5791 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
5792 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
5793 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
5794 to the `config commands' section either.
5795 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
5796 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
5798 ... and many changes to the comments nearby.
5800 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
5801 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
5802 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5803 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
5804 (#define header templates): The comment at the top of the generated
5805 header now includes the name(s) of the source file(s).
5807 Several unrelated small changes:
5809 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
5810 parameter to AC_DIAGNOSE.
5811 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
5812 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
5813 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
5814 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
5815 with AU::AC_OUTPUT.
5816 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
5817 in AC_OUTPUT doesn't double-quote it either.
5818 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
5819 parameters.
5821 2005-07-10 Stepan Kasal <kasal@ucw.cz>
5823 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
5824 versions of Portland Group compiler produce single- and double-quoted
5825 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
5826 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
5828 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
5830 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5831 This is a corrected version of yesterday's patch.
5833 2005-07-07 Stepan Kasal <kasal@ucw.cz>
5835 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
5836 path, too; insert a "===" to emphasize the line.
5838 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
5839 ac_cv_build_alias to ac_build_alias.
5840 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
5842 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
5843 change eliminates it. Problem reported by Alexandre Duret-Lutz.
5844 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
5845 (AC_ARG_VAR): ... here.
5846 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
5847 target_alias.
5849 Keep a list of all precious variables and process them with one simple
5850 for loop, instead of expanding all commands, or, OTOH, complicated
5851 processing of output of "set".
5852 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
5853 variable names in new macro...
5854 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
5855 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
5856 a loop to assign all ac_env_* and ac_cv_env_* variables.
5857 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
5858 to INIT_PREPARE.
5859 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
5860 its value to shell variable ac_precious_vars and call
5861 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
5862 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
5863 _AC_ARG_VAR_VALIDATE.
5865 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
5866 and the AC_SUBSTs ...
5867 (AC_INIT): ... here.
5869 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
5870 the ac_subst_files section in config.log.
5872 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
5874 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

5879 * tests/c.at (C keywords): Test AC_C_TYPEOF.
5881 Fix problems reported by Nicolas Joly.
5882 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
5883 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5884 They are generated by the Tru64 v5.1B shell.
5886 2005-07-05 Stepan Kasal <kasal@ucw.cz>
5888 Fix my changes from 2005-07-01; reported by Noah Misch.
5889 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
5890 description, the macro now accepts only a single tag.
5891 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
5893 Fix cases when the varsions of Autoconf and Autotest don't match.
5894 Reported by Noah Misch.
5895 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
5896 at_top_builddir, for compatibility with older autotest.
5897 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
5898 is not set, use at_top_builddir, for compatibility with older
5899 versions of autoconf.
5901 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
5903 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
5904 Problem reported by Patrick Welche.
5906 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
5908 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
5909 sed substitution command, so that we allow | in program prefixes
5910 and program suffixes. (& is a problem anyway; we're not fixing
5911 that here.)
5912 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
5913 configure_input, top_builddir, srcdir, etc.
5914 * lib/autotest/general.m4 (AT_INIT): Likewise, for
5915 PATH_SEPARATOR in AUTOTEST_PATH.
5917 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
5919 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
5920 for loop over config.site files using `set', to allow
5921 directory names containing IFS characters.
5923 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
5925 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
5926 directories with weird names. Apparently some people like living
5927 on the edge. However, improve the test that "pwd" actually does
5928 report a name for the working directory.
5929 * NEWS: Remove the claim that we test for funny chars in dir names.
5931 2005-07-01 Stepan Kasal <kasal@ucw.cz>
5933 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
5934 replaced ...

5943 about #include <config.h>.
5944 (Generic Functions): Mention the Gnulib project.
5945 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
5947 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
5948 document to output the default config_* lists to config.status.
5949 Don't recognize option --file, if the functionality is not there.
5950 Likewise for --header; moreover, recognize --he and --h as shortcuts
5951 for --help in that case.
5953 * lib/autoconf/status.m4: Fix the order of the "sections", so that it

5976 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
5977 (AC_SUBST): Call it.
5978 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
5979 the directory specific variables; but don't call it for configure_input.
5981 2005-06-28 Derek Price <derek@ximbiot.com>
5983 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
5984 addition.
5986 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
5988 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
5989 directory have inherent problems with special characters like spaces,
5990 due to limitations in Make syntax. Problem reported by Alexandre
5991 Duret-Lutz.
5992 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

6007 variable into diagnostic. Make the diagnostic an error, not a warning,
6008 because we really don't support spaces and suchlike in dir names.
6009 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
6010 Don't worry about backslashes in srcdir; it can't happen now.
6011 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
6012 Simplify ac_optarg handling.

6037 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
6038 b, t, r, w commands require single space, while : cannot have any.
6039 (Special Shell Variables): Fix sed code this in the example.
6040 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
6041 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
6043 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
6044 expand to the empty list. Don't use two pairs of m4_changequote,
6045 it's not necessary.
6047 2005-06-20 Derek Price <derek@ximbiot.com>
6049 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
6051 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
6053 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
6054 * doc/autoconf.texi:
6055 Don't mention Solaris versions so much, if a
6056 problem is common to all extant versions of Solaris. Say "SunOS
6057 4" instead of "SunOS" for SunOS 4.
6058 (awk): Mention more of the limitations of traditional Awk.
6059 (cat): Don't talk about cat -v.
6061 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
6063 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.

6066 to be compatible with glibc strverscmp.
6067 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
6069 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
6070 on Mac OS X 10.4 reported by Peter O'Gorman in:

6072 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
6073 Use shell builtins rather than 'expr', to work around expr bug.
6075 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
6077 * doc/autoconf.texi: "filesystem" -> "file system".
6078 "behaviour" -> "behavior".

6080 * lib/autoconf/general.m4: Omit blank after ":" sed command,
6081 as per POSIX.
6082 * lib/m4sugar/m4sh.m4: Likewise.
6083 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
6084 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
6086 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
6087 (.x.1): Ignore the time stamp in the .TH line when deciding whether
6088 to update the man page. That way, we don't have to check in new
6089 man pages every month.
6091 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
6092 quotes and backslashes. Patch from Derek Price.

6097 AS_TR_SH.
6099 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
6101 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
6102 -u, since it outputs chatter if the input files are the same.
6103 Problem reported by Ralf Menzel.
6105 2005-06-08 Derek Price <derek@ximbiot.com>
6107 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
6108 renaming them since they are about to be redefined anyhow.
6110 2005-06-08 Derek Price <derek@ximbiot.com>
6112 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
6113 redefined M4 macros to this node. Document m4_include & m4_sinclude.
6114 Move m4_undefine to alphabetical order.
6116 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
6118 * README: Recommend GNU M4 1.4.3 or later.
6119 * doc/autoconf.texi (Introduction): Likewise.
6120 Reword to avoid some formatting glitches.
6121 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
6122 Clarify explanation of HP compiler bug.
6123 Redo example output tp match current CVS snapshot.
6124 Use @example.org in email addresses when the examples
6125 might get inadvertently cut-and-pasted into user code.
6126 Remove example of autom4te usage that doesn't seem to work now.
6127 Use modern AC_INIT (except when the example is meant to be
6128 shown with Autoconf 2.13).
6129 Update ksh info for Solaris 9 and later.
6130 KB -> kB.
6131 Modernize description of Automake versions a bit.
6132 Don't claim a future version of Autoconf is near.

6135 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6137 * doc/autoconf.texi: Add [] to examples, so that the manual
6138 follows its own advice about quoting better.
6139 Reword to avoid some formatting glitches.
6140 * doc/installt.exi: Reword to avoid some formatting glitches.
6142 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
6143 Tru64 ksh pattern matching bug. Reported against Libtool by
6144 Albert Chin <libtool@mlists.thewrittenword.com> and
6145 Nicolas Joly <njoly@pasteur.fr>.
6147 2005-06-06 Stepan Kasal <kasal@ucw.cz>
6149 m4_cdr of one-member list was [[]] (one-member list containing an
6150 empty string) instead of [] (an empty list. Callers were skewed to
6151 match this misbehaviour. As a consequence of this:
6152 - m4_foreach([x], [], [foo]) expanded to `foo', while
6153 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
6154 This bug has been fixed:
6156 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
6157 expand to an empty string; print error msg if called without
6158 an argument list.
6159 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
6160 misbehaviour; handle [] and [[]] correctly.
6162 2005-06-06 Stepan Kasal <kasal@ucw.cz>
6164 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

6166 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
6168 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
6170 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
6171 swallow records with more than 99 fields.
6172 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
6173 parse the long line.
6175 2005-06-04 Stepan Kasal <kasal@ucw.cz>
6177 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
6178 swallow literals longer than 399. Reported by Ralf Wildenhues.
6179 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
6180 to workaround this limitation.
6182 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
6184 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
6185 to gfortran, and make these the first two compiler names
6186 checked (following the general autoconf preference for gcc).
6188 2005-06-03 Stepan Kasal <kasal@ucw.cz>
6190 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
6191 (DISTCLEANFILES): Remove $(check_SCRIPTS).
6192 (testsuite): Make sure autotest.m4f is up-to-date before using it.
6194 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
6196 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
6197 expression of unbounded size when processing the --list
6198 option. This runs afoul of a limit of 399 bytes per regular
6199 expression on AIX. Problem reported by Ralf Wildenhues.
6201 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
6203 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
6204 * doc/autoconf.texi (Particular Headers): Reword example
6205 for multiline stdbool replacement.
6206 (Setting Output Variables): Reword text a bit. Don't
6207 give all the details about |#_!!_#|.
6208 Reword description of line replacement.
6210 2005-05-31 Dan Manthey <dan_manthey@partech.com>
6212 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
6213 now contain newlines, and substituted files must be referenced on
6214 a line alone; the sed scripts to substitute them are now very
6215 different.
6216 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
6217 commands can be put in a sed script portably.
6218 * doc/autoconf.texi (Setting Output Variables): Document above
6219 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
6220 use of multiline substitution.

6230 * tests/local.at: Don't attempt to check for negated character
6231 classes in shell scripts. The test was too brittle.
6233 2005-05-25 Stepan Kasal <kasal@ucw.cz>
6235 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
6236 * doc/autoconf.texi (Limitations of Builtins): Document this
6237 limitation.
6239 2005-05-24 Stepan Kasal <kasal@ucw.cz>
6241 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
6242 common code; used in many places in the tree.

6244 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
6246 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
6248 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
6249 messages when ac_unique_file is not found.
6250 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
6251 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
6252 commands, for consistency with AC_MSG_ERROR and such.
6254 * bin/autoconf.as: Make more use of "shift 2" in option processing.

6264 2005-05-20 Stepan Kasal <kasal@ucw.cz>
6266 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
6267 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
6268 (ac_top_builddir): ... this ...
6269 (ac_top_build_prefix): ... to this; the old name is also kept, for
6270 backward compatibility.
6271 (ac_top_builddir_sub): New variable, without the trailing slash,
6272 always nonempty.
6273 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
6274 * doc/autoconf.texi (Configuration Actions): Rename
6275 ac_top_builddir to ac_top_build_prefix.
6276 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
6277 at_top_builddir to at_top_build_prefix.

6285 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6287 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
6288 argument to m4_foreach. I guess it was necessary in the past,
6289 but I think it's a no-op now.
6291 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6293 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
6294 ``cat <<_ACEOF'' commands to one.
6295 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
6296 * lib/autoconf/status.m4: On various places, use expr instead of
6297 ``echo|sed.''
6298 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
6299 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
6300 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
6301 a range.
6302 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
6303 the wrong patterns between ``case'' and ``esac.'' The previous
6304 code had false positives.
6306 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
6308 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
6309 as on 2005-05-02.
6310 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

6372 * doc/autoconf.texi (Autoconf Language): Be more precise about
6373 quoting rules. Problems noted by Stepan Kasal.
6374 Also, throughout this document, be more careful about white space.
6375 "blank", "white space", and "space" all have different meanings
6376 and we should be careful to say what we mean.
6378 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
6380 Fix C++ related problems reported by Werner Lemberg.
6381 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

6401 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
6402 outputs 0 on GNU/Linux these days.
6404 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
6406 * doc/autoconf.texi (Autoconf Language): Add more description
6407 about quoting heuristics.
6408 (Limitations of Builtins): Describe "set -" problems.
6410 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6412 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
6413 not newline.
6415 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
6416 by AC_DEFINE; it was a mistake.
6417 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
6419 2005-04-25 Stepan Kasal <kasal@ucw.cz>
6421 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
6423 2005-04-22 Stepan Kasal <kasal@ucw.cz>
6425 * doc/autoconf.texi (External Software): Quadrigraphs are not
6426 processed correctly in AS_HELP_STRING; avoid this in the examples.
6427 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
6428 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
6429 comment and reduce m4_default([foo], []) to [foo].
6430 (m4_strip): Update the explanation.
6432 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
6434 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
6435 Remove core.conftest.* too; it's generated by Tru64 5.1.
6436 Problem reported by Jennis Pruett.
6437 * lib/autoconf/functions.m4
6438 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
6439 Don't bother to remove core files; AC_RUN_IFELSE should do that
6440 for you.
6442 2005-04-19 Stepan Kasal <kasal@ucw.cz>
6444 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

6461 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
6463 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
6464 as well as configure.in. Problem reported by Gregorio Guidi.
6466 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
6468 * doc/autoconf.texi (Particular Functions): Use gnulib's current

6482 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
6484 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6486 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
6487 Merge `-z option' as well for the benefit of Solaris link flags. Pass
6488 whole-archive (-zallextract, -zdefaultextract) options in the hope of
6489 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
6490 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
6492 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
6494 * NEWS: The configure command now warns you if you attempt to use
6495 a directory whose name contains a special character like space,
6496 newline, or "\".
6497 * doc/autoconf.texi (Installation Directory Variables): Allow
6498 "," in file names. Do not use \@; it's not a portable regexp.
6499 * bin/Makefile.am (edit): Likewise.
6500 * lib/Makefile.am (edit): Likewise.
6501 * tests/Makefile.am (edit): Likewise.
6502 * tests/semantics.at: Likewise.

6509 (AC_INIT): Use it.
6510 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
6511 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
6512 ac_pwd, and quote srcdir.
6513 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
6515 * doc/autoconf.texi: Fix some systematic formatting problems.
6516 ".)" needs a following @: if not at the end of a sentence, and
6517 similarly for "!)". "etc." should be preceded by a comma.
6518 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
6520 2005-03-22 Bruno Haible <bruno@clisp.org>
6522 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
6523 argument is often called 'build-aux'.
6525 2005-03-07 Stepan Kasal <kasal@ucw.cz>
6527 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
6528 macro AC_TRY_LINK is obsolete.
6529 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
6530 `AC_CONFIG_FILES'.
6532 2005-02-24 Stepan Kasal <kasal@ucw.cz>
6534 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
6535 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
6536 from a Common Lisp's `cl'.
6537 (AC_PROG_CXX): Behave according to the documentation: don't
6538 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
6539 make the variable CCC precious; use `cl.exe', not `cl'.
6541 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6542 Alexandre Duret-Lutz <adl@gnu.org>
6544 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
6545 /dev/null, as "configure" shouldn't read stdin, and this insulates
6546 us from problems (e.g., when testing for "cl"). Also, do this
6547 redirection before invoking "hostname" or "uname", and keep the
6548 original input stream available via...
6549 (AS_ORIGINAL_STDIN_FD): ... this new macro.
6550 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
6551 bother with "</dev/null" since it's now done at the top of
6552 'configure'.
6553 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
6554 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

6558 * tests/base.at (Input/Output): New test.
6560 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6562 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
6563 newline if neither \c nor -n work, as that would output two
6564 newlines. Prefer -n to \c. Reported by Stepan Kasal.
6566 2005-02-12 Stepan Kasal <kasal@ucw.cz>
6568 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
6569 This causes that any required macros inside will get before the if.
6570 * doc/autoconf.texi (autom4te.cache): A typo.
6572 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
6574 Undo previous change, except keep the change to
6575 lib/autoconf/programs.m4 that replaced grep with shell
6576 pattern-matching. This is because net-snmp configure reads stdin.
6577 Reported by Noah Misch.
6579 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
6581 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
6582 from /dev/null, as "configure" shouldn't read stdin, and this
6583 insulates us from problems (e.g., when testing for "cl").
6584 Suggested by Alexandre Duret-Lutz. Also, do this redirection
6585 before invoking "hostname" or "uname".
6586 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6587 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
6588 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
6589 "</dev/null" since it's now done at the top of 'configure'.
6590 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6591 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6592 Also, replace grep with shell pattern-matching, to save a process.
6594 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
6596 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6597 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
6598 avoid thinking that Allegro Common Lisp's "cl" command is a C++
6599 compiler.
6601 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
6603 * doc/autoconf.texi (Limitations of Usual Tools): Document that
6604 grep -q isn't portable. Improve grep -s explanation.
6605 Problem reported by Dan Manthey.
6607 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
6609 * doc/autoconf.texi (Special Shell Variables): Clarify
6610 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
6612 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
6614 * doc/autoconf.texi: Use @acronym for DJGPP.
6615 Fix some @code's that should have been @env's, and vice versa.
6616 Sort environment variable names.
6617 Mention that shells no longer inherit IFS.
6618 Don't recommend PATH_SEPARATOR=';' so strongly.
6619 Mention that $RANDOM might expand to the empty string.
6620 "symlink" and "soft link" -> "symbolic link".
6621 Improve mktemp description (reported by Bruno Haible).
6623 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
6625 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
6626 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
6627 Likewise.
6628 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
6629 Likewise.
6631 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
6633 * NEWS: Mention AT_COPYRIGHT.
6635 * tests/local.at (AT_CMP): Use diff directly on input files rather
6636 than copying them.
6638 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
6639 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
6641 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6642 and Paul Eggert <eggert@cs.ucla.edu>
6644 * tests/autotest.at (Empty test suite): New test.

6649 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6651 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
6652 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
6653 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
6654 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
6655 (Standard regular expressions): New test.
6656 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
6657 excess test name quoting.
6658 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
6659 CPPFLAGS to `configure' instead of setting it in `configure'.
6661 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
6662 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
6663 on some platforms.
6665 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
6666 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

6694 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
6696 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
6697 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
6699 Try not to generated lines of unlimited length, as POSIX places a
6700 2047-byte limit on line length of portable text files.
6701 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
6702 Use newline as a separator, not space.

6704 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
6705 space.

6709 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
6710 as_func_*. Add test to check whether positional parameters
6711 are restored after function return.
6713 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
6715 * doc/autoconf.texi (Special Shell Variables): Mention _,
6716 BIN_SH, DUALCASE. Say that variables other than "status" are safe
6717 if they contain a lower-case letter. The DUALCASE problem was
6718 reported by Ralf Wildenhues.
6720 * bin/autoconf.as: Don't exit with status 0 after write failure
6721 with --help or --version.
6722 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

6728 Unicos 9 sed limitations.
6729 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

6731 Fortran 95 (newer Crays).
6733 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
6735 * man/Makefile.am (.x.1): Go back to the simple solution, but take
6736 care to echo the commands, so the user knows what's going on.
6737 Modified from a suggestion by Stepan Kasal.
6739 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

6746 * doc/install.texi (Defining Variables): Likewise.
6747 Based on a proposed patch by Ralf Wildenhues.
6749 * man/Makefile.am (.x.1): Make sure the required generated files
6750 are up to date. Problem and original solution proposed by Stepan Kasal.
6751 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
6752 implicit-man-prerequisites): New rules, used by the above.

6758 2005-01-29 Stepan Kasal <kasal@ucw.cz>
6760 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
6761 Update the long comment explaining it.
6763 m4_require no longer writes an ``is required by'' line to the
6764 execution stack. It contains only one bit of non-redundant
6765 information: that the macro was required, not called. And even
6766 this bit is useless in most situations: have you ever met a macro
6767 which both calls and requires the same macro?
6769 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
6770 (_m4_defun_pro_outer): ... only via this macro, for the outermost
6771 macro.
6772 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
6773 (m4_expansion_stack_pop): Remove the misplaced comment.
6774 (m4_require): Don't put the ``is required by'' line to the
6775 execution stack; slightly improve the out-of-a-defun error message.
6776 (_m4_divert_grow): New macro, counter for the temporary diversions.
6777 (_m4_require_call): Use it.
6778 * tests/m4sugar.at (m4_require): Expect output without the
6779 ``is required by'' messages.
6781 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
6783 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
6784 rather than x for expr.
6786 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
6787 this is safe.
6788 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

6799 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
6800 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
6801 from masters, so that FileUtils.pm's update_file provide --force
6802 support.
6803 * bin/autoheader.in: Pass $force to update_file so that
6804 config.h.in is always recreated when --force.
6806 2005-01-24 Stepan Kasal <kasal@ucw.cz>
6808 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
6810 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
6812 * doc/autoconf.texi (Limitations of Builtins): Clarify that
6813 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
6815 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
6817 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
6818 Warn about newline stripping in `` and $(). Update Solaris
6819 version to 9.
6820 (Limitations of Builtins): Use expr "X...", not expr "x...", as
6821 X insulates us from future changes to Posix.
6822 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
6823 stripping.
6825 2005-01-19 Stepan Kasal <kasal@ucw.cz>
6827 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

6843 ulongval to be static, to avoid unwanted GCC warning. Problem
6844 reported by Michael Jennings via Daniel Reed; see
6845 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.

7189 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
7190 "char c = '\200';" rather than "char c = 0x80;" as the

7310 (trivial change). Problem and patch reported by Andrew Church in:
7311 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
7313 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
7315 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
7316 three args in examples. Problem reported by Frederik Fouvry in:
7317 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
7318 Also, fix some minor spacing and punctuation bugs.
7320 2004-09-02 Akim Demaille <akim@epita.fr>
7322 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
7323 "case" to restore ordering.
7324 Reported by Stepan Kasal.
7326 2004-08-26 Akim Demaille <akim@epita.fr>

7340 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
7341 texinfo.tex for now (done by hand now).
7342 * Makefile.maint (wget_files, cvs_files):
7343 Remove ansi2knr.c; nobody uses it.
7344 (ansi2knr.c-url_prefix): Remove.
7345 (cvs-update): Fix test for failure. I don't know why it ever
7346 worked...
7348 * doc/autoconf.texi: Update URLs, some of which went stale.
7349 Use @uref rather than @href.
7351 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
7352 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
7354 * config/config.guess, config/config.sub, config/elisp-comp,
7355 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
7356 doc/fdl.texi, doc/standards.texi: Sync with master copy.
7358 * NEWS, TODO, configure.ac, bin/autoscan.in,
7359 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
7360 doc/install.texi, lib/Autom4te/Configure_ac.pm,

7364 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
7365 tests/tools.at, tests/torture.at:
7366 Use "file name" rather than "filename" or "path",
7367 to be consistent with the terminology of the GNU coding standards.
7369 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
7371 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
7372 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
7373 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
7374 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
7376 More fixes to support spaces in the name of the build directory.
7377 This isn't a complete fix but it's an improvement.
7379 * bin/autoconf.as (autom4te_options): New var.
7380 Use it instead of appending to AUTOM4TE, so that we can allow
7381 spaces in the build directory's absolute name.
7382 * bin/autoheader.in ($autoconf): Allow spaces in file names.
7383 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
7384 AT_CHECK_NOESCAPE): Likewise.
7385 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
7386 main program): Likewise.
7388 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
7390 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
7391 From Ralf Corsepius in:
7392 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
7394 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
7396 * doc/autoconf.texi (Function Portability): Document isinf and
7397 and isnan. From a suggestion by Kevin Ryde.
7399 * lib/Autom4te/General.pm (END): Return correct exit status even
7400 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
7402 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
7404 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
7405 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
7406 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
7408 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
7410 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
7411 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
7412 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
7413 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
7414 * lib/autom4te.in (Automake-preselections): Preselect
7415 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
7417 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
7419 * lib/autom4te.in (Automake-preselections): Preselect
7420 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
7421 trace them.
7423 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
7425 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
7426 Tru64.
7427 * doc/autoconf.texi (Shellology): Mention BIN_SH.
7428 Document problem with "`""`" in pdksh POSIX mode.
7430 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
7432 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
7433 with pdksh, too. Problem reported by Patrick Welche via
7434 Gary V. Vaughan.
7435 * doc/autoconf.texi (Shellology): Note that set -o posix is
7436 useful for pkdsh, too.
7438 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
7440 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
7441 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
7442 Don't fail if ENV or BASH_ENV is readonly.
7443 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
7444 etc. are read only. Problem reported by Ludovic Courtes.
7446 2004-06-23 Noah Misch <noah@cs.caltech.edu>
7448 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
7449 zsh, disable GLOB_SUBST to avoid backslash handling problems.
7450 (trivial change)
7452 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
7454 * doc/autoconf.texi (File System Conventions): Warn about
7455 names like "aux". Problem reported by Eric Blake.
7457 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
7458 by zero instead of array size, so that we can use any arithmetic
7459 constant expression (instead of requiring an integer constant
7460 expression). This allows us to test expressions like DBL_MAX <
7461 LDBL_MAX, which didn't conform to the C standard using the old
7462 method.
7463 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
7464 now that we can do floating-point tests at compile time.
7466 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
7468 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
7469 and LDBL_EPSILON, as the resulting expression isn't an
7470 integer constant expression and violates the C standard.
7471 Problem reported by Nelson H. F. Beebe. Also, check
7472 for "L" suffix, and check that long double doesn't have
7473 worse range or precision than double, that mixed-mode
7474 arithmetic doesn't generate a diagnostic, that double
7475 constants fit in long double.
7477 2004-06-03 Kevin Ryde <user42@zip.com.au>
7479 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
7480 malloc(0) and realloc(NULL,size).
7482 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
7483 Bob Proulx.
7485 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
7487 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
7488 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
7489 by Jim Meyering.
7491 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
7493 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
7494 can be rewritten using if-then-else. Suggested by Bruno Haible.
7496 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
7498 * doc/autoconf.texi (testsuite Scripts): Fix typo.
7499 Problem reported by Stepan Kasal.
7501 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
7503 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
7504 change). Patch reported by Ralf Wildenhues in
7505 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
7507 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
7508 function F exists if the compiler and linker let you compile an
7509 expression like (F != 0). Recent versions of GCC optimize away
7510 the reference to F in that case, since every function address must
7511 be nonzero, so the link succeeds even if F does not exist.
7512 Problem reported by Manu in
7513 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
7515 * doc/autoconf.texi (Systemology): Standardize on the spelling of
7516 "Unix". Many uses changed.
7517 (Limitations of Builtins): Explain better why the ! command isn't
7518 portable.
7520 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
7522 * lib/autom4te.in (Automake-preselections): Preselect
7523 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
7525 2004-05-19 Kevin Ryde <user42@zip.com.au>
7527 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
7528 referencing AC_FUNC_STRERROR_R.
7530 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
7531 note pessimistic assumption when cross compiling.
7533 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
7535 * doc/autoconf.texi (Limitations of Make): Note that BSD make
7536 (until 2004) invoked subcommands with sh -e, contra POSIX.
7537 Reported by Kevin Ryde.
7539 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
7541 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
7542 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
7543 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
7544 `test -f " /usr/bin/grep"', which _always_ failed.
7545 (AC_PROG_SED): Ditto bogus PATH fix.
7546 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
7547 requires that grep correctly supports _multiple_ `-e' options, rather
7548 than stating only that grep should accept `-e'.
7550 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
7552 Port to C99, which requires that 'exit' be declared.
7554 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
7555 to ensure that stdlib.h is included.
7556 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
7557 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
7558 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
7559 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
7560 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
7561 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
7562 when using 'exit' in a test; C99 requires that 'exit' be declared.
7564 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
7566 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
7567 now prefers 'grep' implementations that accept -e.
7568 (Limitations of Usual Tools): Describe problems of traditional
7569 egrep and fgrep with long input lines, and of traditional grep
7570 with -e.
7571 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
7572 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
7573 All callers changed. Append /usr/xpg4/bin to the PATH, for
7574 Solaris.
7575 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
7576 the user with complaints about multiple -e options.
7577 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
7578 Define it with AC_PROG_GREP.
7579 * configure.ac (AC_PROG_GREP): Add.
7580 * lib/freeze.mk (GREP): New macro.
7582 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
7584 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
7585 a possible candidate only after all others fail, rather than
7586 consulting it first. This improves backward compatibility by
7587 better reflecting the way shell selection occurred in previous
7588 versions of Autoconf, and should help to avoid triggering latent
7589 problems in other packages, such as the one in Automake where zsh
7590 is not handled robustly:
7591 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
7592 Although it is not Autoconf's responsibility to work around
7593 problems in Automake, it nevertheless makes sense to avoid
7594 introducing unnecessary incompatibilites.
7596 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
7597 Gary V. Vaughan <gary@gnu.org>
7599 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
7600 how deeply nested we are when a suitable tool is found, set the
7601 ac_path_TOOL_found flag.
7602 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
7603 nested we are in this macro. Break out of all 3 nested loops if
7604 ac_path_TOOL_found is set.
7606 2004-04-21 Gary V. Vaughan <gary@gnu.org>
7608 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
7609 of the _AS_PATH_WALK loop too if GNU flavor is found.
7611 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
7613 * doc/autoconf.texi (Limitations of Make): Update documentation
7614 for `$<'. New entry `Long lines', based on a report from Simon
7615 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
7616 paragraph about DJGPP, based on a mail from Richard Dawe.
7618 2004-04-20 Paul Eggert <eggert@twinsun.com>
7620 * tests/c.at (C keywords): Don't assume that GCC supports
7621 "restrict" and "inline", as sufficiently-old GCC versions do not
7622 (also, GCC configured to be in pedantic C89 mode does not).
7623 Problem reported by Sumit Pandya in:
7624 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
7626 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
7627 consider -g to work if it generates warnings when plain compiles
7628 don't. Problem reported by Braden McDaniel in:
7629 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
7631 * doc/autoconf.texi (Slashes): New section, to document a problem
7632 reported by Jim Meyering in:
7633 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
7635 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
7636 linker output files before linking, to work around IRIX 6 linker bug.
7637 Problem reported by Rainer Orth in:
7638 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
7640 2004-04-20 Gary V. Vaughan <gary@gnu.org>
7642 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
7643 best tool so far counter rely on the tool path variable name to
7644 avoid checks for one tool being affected by the results of running
7645 the length check on a previous tool.
7647 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
7648 match expression argument, as different greps have different
7649 regular expression flavours.
7650 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
7651 literals.
7652 (AC_PROG_EGREP): Pass 'EGREP$'.
7653 (AC_PROG_GREP): Pass 'GREP$'.
7655 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
7657 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
7658 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
7660 2004-03-29 Paul Eggert <eggert@twinsun.com>
7662 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
7663 Types, Specific Compiler Characteristics, System Services,
7664 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
7665 etc. consistently instead of 'long', 'short', 'unsigned' etc.
7666 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
7667 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
7668 Likewise.
7669 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
7670 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
7671 AC_TYPE_OFF_T): Likewise.
7672 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
7673 Likewise.
7675 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
7676 pacify libtool 1.5.2. Fix quoting problems in sed command.
7678 2004-03-28 Paul Eggert <eggert@twinsun.com>
7680 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
7681 now defines HAVE_DECL_TZNAME if it is declared, when
7682 HAVE_STRUCT_TM_TM_ZONE is not defined.
7683 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
7684 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
7685 for HAVE_TZNAME.
7687 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
7689 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
7690 superfluous backslashing of quotes (") in sed expressions;
7691 thanks to Paul Eggert.
7693 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
7695 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
7696 Fortran compiler is ifort, also added pghpf; thanks to Nelson
7697 H. F. Beebe for the bug report.
7699 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
7701 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
7702 quoted -cmdline argument in Portland Group compiler (bug
7703 reported by Jeffrey J. Barteet).
7705 2004-03-25 Kevin Ryde <user42@zip.com.au>
7707 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
7708 (Run Time): ... here, where it's now mentioned.
7710 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
7712 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
7713 inherits from language Autoconf-without-aclocal-m4.
7714 (Customizing autom4te): Adjust example; the cache must now be
7715 disabled for language Autoconf-without-aclocal-m4.
7717 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
7718 Nathanael Nerode <neroden@twcny.rr.com>
7720 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
7721 AC_CHECK_TOOLS): Warn if a cross-tool is found without
7722 a prefix.
7723 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
7724 AC_CHECK_TARGET_TOOLS): New macros.
7725 * doc/autoconf.texi (Generic Programs): Document
7726 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
7727 AC_CHECK_TARGET_TOOLS, and warn for future changes
7728 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
7729 AC_CHECK_TOOLS.
7730 (Specifying Names): Document the reason for these future
7731 behavioral changes.
7732 * tests/mktests.sh: Do not generate tests for the
7733 new macros.
7734 * NEWS: Document these changes.
7736 * doc/autoconf.texi: Avoid macros with unbraced arguments,
7737 they make TeX hang up.
7739 2004-03-15 Paul Eggert <eggert@bogus.example.com>
7741 * NEWS: New macro AC_CHECK_ALIGNOF.
7742 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
7743 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
7744 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
7745 vowel.
7746 (AC_CHECK_ALIGNOF): New macro.
7747 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
7748 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
7749 those for sizeof.
7751 2004-03-03 Paul Eggert <eggert@twinsun.com>
7753 * bin/Makefile.am (edit): Don't use $< in a context where
7754 POSIX doesn't require support for it. Use $@.in instead.
7755 Problem reported by Anthony N. Frasso in
7756 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
7757 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
7759 2004-02-23 Gary V. Vaughan <gary@gnu.org>
7761 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
7762 from the next generation of Libtool.
7763 * lib/autom4te.in (Autoreconf-preselections): Ditto.
7765 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7767 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
7768 is not always thread-safe. Report from Nathanael Nerode.
7770 2004-02-18 Paul Eggert <eggert@twinsun.com>
7772 Fix a dependencies problem, stemming from a Autoconf 2.59 build
7773 problem on QNX reported by Stephen Rasku in
7774 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
7776 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
7777 $(m4sh_m4f_dependencies); this removes a FIXME.
7778 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
7779 (MAINTAINERCLEANFILES): Split into pieces,
7780 one per related section. Add $(srcdir)/wrapper.in.
7782 2004-02-09 Paul Eggert <eggert@twinsun.com>
7784 * doc/autoconf.texi (Setting Output Variables): Emphasize that
7785 AC_SUBST provides no portable way to escape literal newlines.
7787 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
7788 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
7789 Darwin uses -lcrt2.o and there's little point to cataloging all
7790 the system variants. Partial fix reported by Andreas Waechter in:
7791 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
7792 for bug reported by Nelson H. F. Beebe in:

7795 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
7797 * doc/autoconf.texi (AU_DEFUN): Fix English,
7798 suggested by Paul Eggert.
7799 * lib/autoconf/autoupdate.m4: Correct reference to
7800 acobsolete.m4, suggested by Alexandre Duret-Lutz.
7802 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
7804 * bin/autoupdate.in: Define __file__ so that warnings
7805 refer to the correct file.
7806 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
7807 the behavior of the third argument.
7808 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
7809 correctly the behavior of the third argument. Document
7810 what the three macros that AU_DEFUN defines do. Fix
7811 warning message when the third argument includes $0
7812 (reported by Alexandre Duret-Lutz).
7814 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
7815 Eric Sunshine <sunshine@sunshineco.com>
7816 Paul Eggert <eggert@twinsun.com>
7818 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
7819 (AS_INIT): Output shell initialization there. Removed optional
7820 parameter. Expand _AS_SHELL_FN_SPY.
7821 (AS_INIT_WITH_SHELL_FN): Removed.
7822 (_AS_SHELL_FN_SPY): New macro.
7823 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
7824 macros.
7825 (AS_SHELL_SANITIZE): Remove loop to find better shell
7826 and documentation for the parameter.
7827 (_AS_DETECT_BETTER_SHELL): Move it here.
7828 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
7829 (_AS_RUN): Move it here, support testing with eval.
7830 (AS_REQUIRE_SHELL_FN): Require shell functions when
7831 it is used.
7832 (_AS_LINENO_WORKS): Put around braces, we do not
7833 trigger the bash bug anymore.
7834 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
7835 use AS_INIT_WITH_SHELL_FN.
7836 * bin/autoconf.in, tests/wrapper.in: Regenerated.
7838 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
7840 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
7841 * doc/autoconf.texi: Don't say that the third parameter
7842 is broken.
7843 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
7844 (AU_DEFUN): Honor the third parameter, create autoupdate
7845 macros with AU_DEFINE.
7846 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
7847 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
7848 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
7849 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
7850 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

7854 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
7855 * lib/autoconf/status.m4: Remove FIXME.
7856 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
7857 that the macro is not present anymore in the updated
7858 configure.ac.
7859 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
7860 of autoupdate.
7862 2004-01-28 Paul Eggert <eggert@twinsun.com>
7864 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
7865 copyright years.
7866 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
7867 2003 (except 1997) to the list of copyright years. This undoes
7868 the 2003-05-22 change, which removed the older years from the list.
7869 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
7871 2004-01-27 Gary V. Vaughan <gary@gnu.org>
7872 Albert Chin-A-Young <china@thewrittenword.com>
7874 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
7875 grep or ggrep program in PATH that accepts as long lines as
7876 possible.
7877 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
7878 AC_PROG_GREP.
7879 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
7880 egrep and fgrep respectively if $GREP -E/-F don't work.
7881 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
7882 _AC_PROG_GREP, and AC_PROG_SED.
7883 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
7884 longest input length accepted by a command.
7885 (AC_PROG_SED): Use it.
7886 * doc/autoconf.texi (Particular Programs): Document the changes.
7887 * NEWS: Updated.
7889 2004-01-27 Paul Eggert <eggert@twinsun.com>
7891 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
7892 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
7893 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
7894 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
7896 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
7897 bin/autoconf.in, config/Makefile.in, config/config.guess,
7898 config/config.sub, config/install-sh, config/mdate-sh,

7909 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
7910 tests/actypes.at: Regenerate and/or sync with original
7911 sources.
7913 2004-01-26 Paul Eggert <eggert@twinsun.com>
7915 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
7916 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
7917 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
7918 not <inttypes.h>. Problem reported by Tim Mooney in
7919 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
7920 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
7921 Likewise.
7923 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
7924 otherwise "make check" fails because it forbids cmp (I guess
7925 because cmp treats files as binary on DOS-like systems).
7927 * tests/mktests.sh: Update copyright date to 2004, since some tests
7928 have changed in 2004.
7930 2004-01-23 Gary V. Vaughan <gary@gnu.org>
7932 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
7933 non-truncating sed or gsed program in PATH.
7934 * tests/acprograms.at: Add it.
7935 * doc/autoconf.texi (Particular Programs): Document it.
7936 * NEWS: Updated.
7938 2004-01-15 Paul Eggert <eggert@twinsun.com>
7940 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
7941 -std1 disables some useful extensions on Tru64. Problem reported
7942 by N. Lichtmaier in
7943 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
7945 2004-01-14 Paul Eggert <eggert@twinsun.com>
7947 * doc/autoconf.texi (Programming in M4sh): Document that
7948 AS_MKDIR_P succeeds if the destination is a symbolic link
7949 to an existing directory.
7950 (Limitations of Usual Tools): Note that mkdir -p might not
7951 succeed on symlinks to directories.
7953 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
7955 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
7956 * bin/autoheader.in: Grammar fix in message.
7957 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
7958 Test for dir before calling mkdir -p. (trivial changes)
7960 2004-01-13 Eric Blake <ebb9@byu.net>
7962 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
7963 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
7965 2004-01-10 Jim Meyering <jim@meyering.net>
7967 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
7969 2004-01-09 Paul Eggert <eggert@twinsun.com>
7971 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
7972 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
7973 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
7974 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
7975 AC_COMPILE_IFELSE, since we now assume our caller invokes
7976 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
7977 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
7978 of AC_RUN_IFELSE; this avoids the warning mentioned above.
7979 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
7981 2004-01-07 Paul Eggert <eggert@twinsun.com>
7983 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
7984 `"'...'"`, as it's confusing (and I suspect it may not work on
7985 some platforms). The code was incorrect anyway, as it assumed
7986 that \$ evaluated to itself in that context. Reported by
7987 Alexandre Duret-Lutz.
7989 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
7991 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
7992 and _LT_AC_TAGCONFIG.
7994 2004-01-06 Paul Eggert <eggert@twinsun.com>
7996 * doc/autoconf.texi (One Macro Call): Fix an incorrect
7997 example, and add more examples. Reported by Eric Sunshine.
7999 2004-01-05 Paul Eggert <eggert@twinsun.com>
8001 * doc/autoconf.texi (Limitations of Usual Tools):
8002 Remove warning against "rm -fr" introduced yesterday; it
8003 was a false alarm.
8005 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
8006 autoscan, autoupdate, ifnames): Don't use chmod -w.
8007 * lib/Makefile.am (autom4te.cfg): Likewise.
8008 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
8009 "chmod -w".
8011 2004-01-04 Paul Eggert <eggert@twinsun.com>
8012 Paolo Bonzini <bonzini@gnu.org>
8014 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
8015 by doing lineno substitution only on lines containing "$LINENO".
8017 2004-01-04 Paul Eggert <eggert@twinsun.com>
8019 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
8020 Use "rm -f" to remove conftest.sed, not plain "rm".
8021 Bug reported by David Relson in
8022 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
8024 * Makefile.am (autom4te-update):
8025 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
8026 * Makefile.maint (my-distcheck, do-po-update): Likewise.
8027 * doc/autoconf.texi (Guidelines): Likewise.
8028 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

8033 * tests/Makefile.am (clean-local): Likewise.
8034 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
8035 srcdir): Likewise.
8036 * doc/autoconf.texi (Limitations of Usual Tools):
8037 Warn against "rm -fr".
8039 2004-01-03 Paul Eggert <eggert@twinsun.com>
8041 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
8042 -c -o might not work. From a suggestion by Kevin Ryde.
8043 (C Compiler, Generating Sources, Limitations
8044 of Usual Tools, Limitations of Make, Making testsuite Scripts):
8045 Don't put '-o' after non-options, as POSIX doesn't allow this.
8046 Mention that cc's name might be gcc or c89 or whatever.
8048 2004-01-04 Kevin Ryde <user42@zip.com.au>
8050 * doc/autoconf.texi: Add various further index entries.
8052 2003-12-29 Paul Eggert <eggert@twinsun.com>
8054 * bin/autoreconf.in (autoreconf_current_directory):
8055 Fix typo: mkdir without umask arg.
8057 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
8059 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
8060 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
8061 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
8062 explanation clearer.
8064 2003-12-24 Andreas Schwab <schwab@suse.de>
8066 * doc/autoconf.texi (Default Includes): Fix misspelling of
8067 AC_INCLUDES_DEFAULT.
8069 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
8071 * configure.ac: Test if sh -n works.
8072 * configure: Regenerate.
8073 * tests/atlocal.in: Store the result here.
8074 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
8075 tools.at, looking in atlocal's ac_cv_sh_n_works instead
8076 of explicitly testing.
8077 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
8078 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
8079 * tests/tools.at (Syntax of the shell scripts): Simplify
8080 using AT_CHECK_SHELL_SYNTAX.
8081 (Syntax of the Perl scripts): Remove definition of
8082 AT_CHECK_PERL_SYNTAX.
8084 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
8086 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
8087 stderr to /dev/null.
8088 * bin/autoconf.in: Regenerate.
8089 * bin/wrapper.in: Regenerate.

8093 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
8094 Extracted from AS_SHELL_SANITIZE.
8095 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
8096 macros.
8097 (AS_SHELL_SANITIZE): Move reinvocation code from
8098 _AS_LINENO_WORKS, use it to find out if shell
8099 functions work.
8100 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
8101 does not work.
8102 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
8103 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
8104 was called.

8113 * config/announce-gen (&print_locations, &print_signatures)
8114 (&sizes): New.
8115 Use them.

8117 them on the fly.
8119 2003-11-24 Akim Demaille <akim@epita.fr>
8121 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

8149 parameter of AU_DEFUN.
8150 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.

8152 Use AC_DEFUN directly, not AU_DEFINE.

8154 the expanded body, consistently with other macros such as AC_USG.
8156 2003-11-17 Paul Eggert <eggert@twinsun.com>
8158 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
8159 into the initial confdefs.h, to work around a bug in NextStep 3.3
8160 patch 3 reported by Eric Sunshine.
8162 2003-11-15 Kevin Ryde <user42@zip.com.au>
8164 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
8165 than $target since the latter is not usual, add guidelines on when to
8166 use or not use the system type.
8168 2003-11-12 Derek Price <derek@ximbiot.com>
8170 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
8171 typo misrepaired by an auto-spellcheck.
8173 2003-11-12 Akim Demaille <akim@epita.fr>

8176 --force-missing unless it actually supports it.
8177 From Debian #219336.
8179 2003-11-12 Akim Demaille <akim@epita.fr>
8181 * configure.ac: Bump to 2.59a.

8190 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE
8191 so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,

8199 2003-11-05 Kevin Ryde <user42@zip.com.au>

8325 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
8326 cross test.
8328 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
8330 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official

8342 Issue a more-informative diagnostic.
8343 Problems reported by Eric Sunshine.
8345 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
8347 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
8348 -mGLOB_options_string stuff for Intel ifc, which can cause

8372 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
8373 cache variable instead of $G77 to decide whether to include -O2,
8374 since $G77 is specific to Fortran 77.

8378 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
8379 free" flag. Re-order flags tested into rough order of popularity.
8381 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
8383 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
8384 arguments so that it can be used with syntax identical to
8385 AC_PROG_F77, and so that we can more easily decide to
8386 remove/deprecate the DIALECT optional argument in the future if it
8387 proves troublesome.
8388 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
8389 non-freeform-supporting compilers. Document freeform flags.
8391 2003-10-03 Akim Demaille <akim@epita.fr>
8393 * configure.ac: Look for emacs, not macs.

8403 2003-10-03 Akim Demaille <akim@epita.fr>
8405 * configure.ac: Quotation and formatting changes.

8428 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
8430 2003-09-30 Akim Demaille <akim@epita.fr>
8432 * config/announce-gen (&print_news_deltas): Extracted from...
8433 (&print_changelog_deltas): here.

8452 Problem reported by Lars J. Aas in
8453 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
8454 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
8455 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
8456 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
8458 2003-09-26 Akim Demaille <akim@epita.fr>
8460 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
8461 directory for AC_CONFIG_COMMANDS' first argument exists.
8462 This makes valid the invocation of _AC_SRCPATH that follows.
8463 Reported by Eric Sunshine.
8464 * doc/autoconf.texi (Configuration Commands): Adjust.
8466 2003-09-26 Akim Demaille <akim@epita.fr>
8468 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
8469 Reported by Ralf Corsepius.
8471 2003-09-26 Akim Demaille <akim@epita.fr>
8473 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
8474 arguments.
8475 Actually, use AU_ALIAS.
8476 From Bruno Haible.
8478 2003-09-26 Paul Eggert <eggert@twinsun.com>
8480 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
8481 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
8482 Problem reported by Eric Sunshine in:

8485 2003-09-26 Akim Demaille <akim@epita.fr>
8487 The test suite are sometimes assigning timings incorrectly.
8488 Reported by Henk Krus.
8489 Diagnosed by Nicolas Joly.
8491 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
8492 AT_help_all.
8493 Instead of making AT_help a sequence of assignments to grow
8494 $at_help_all, just make AT_help_all be the growing contents of
8495 $at_help_all, and make a single assignment in...
8496 (AT_INIT): here.
8497 (at_times_skip): Flip the meaning and rename as...
8498 (at_times_p): this.
8499 (AT_INIT): When summarizing the test that ran, remove
8500 $at_times_file after use, and check it is present before trying to
8501 use it.
8503 2003-09-25 Akim Demaille <akim@epita.fr>
8505 Version 2.57d.
8507 * bin/Makefile.am (edit): Handle '@configure_input@'.

8509 (ifnames): chmod -w.
8510 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
8511 executables, not bin/ executables! Otherwise all the magic needed
8512 to find non installed files is turned off. This caused a failure
8513 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
8514 as found in its environment (sent by tests/autoreconf): pointing
8515 to bin/autom4te that could not find its files.
8516 * tests/mktests.sh: Force the replacement of generated files, for
8517 the sake of "mv" program that are interactive when overwriting a
8518 -w file.
8519 * config/install-sh: Upgrade from CVS Automake.
8521 2003-09-23 Paul Eggert <eggert@twinsun.com>
8523 * doc/autoconf.texi (Limitations of Builtins): Document test -h
8524 versus test -L issues.
8526 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
8527 Paul Eggert <eggert@twinsun.com>
8529 Trivial change to support GCC's configuration procedure.
8530 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
8531 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
8532 about inconsistency if the preprocessor is set to give errors for
8533 any warning.
8534 * doc/autoconf.texi (C Compiler Characteristics): Document this.
8536 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

8552 2003-09-12 Akim Demaille <akim@epita.fr>
8554 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
8555 not asm/types.h.
8557 2003-09-11 Akim Demaille <akim@epita.fr>
8559 * doc/autoconf.texi (Header Portability): linux/random.h.
8560 From Peter Hendrickson.
8562 2003-09-10 Akim Demaille <akim@epita.fr>
8564 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
8565 willing to edit the output files.
8567 2003-09-10 Akim Demaille <akim@epita.fr>
8569 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
8570 and AC_FC_FREEFORM.
8571 * tests/mktests.sh: Skip AC_FC_SRCEXT.
8572 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
8574 2003-09-09 Akim Demaille <akim@epita.fr>

8587 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
8588 Improve the accuracy of the wording about obsolescence.
8589 From a suggestion by Ian Lance Taylor in
8590 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
8592 2003-09-05 Paul Eggert <eggert@twinsun.com>
8594 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
8595 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
8597 2003-09-04 Akim Demaille <akim@epita.fr>
8599 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
8600 AC_FUNC_WAIT3.
8602 2003-09-04 Akim Demaille <akim@epita.fr>
8604 * bin/autom4te.in: Use &fatal where more appropriate than &error.
8605 (freeze): When exiting, use $exit_code.
8606 * lib/autoconf/fortran.m4: Comment changes.
8608 2003-09-04 Akim Demaille <akim@epita.fr>
8610 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
8612 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
8614 Add support for newer Fortran dialects. The F77 interface is
8615 unchanged, and continues to support Fortran 77. New FC macros
8616 correspond to all the old F77 macros, with output variables FC,
8617 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
8618 available dialect, but older dialects can be specified. There are
8619 new macros AC_FC_SRCEXT to set the source extension, and
8620 AC_FC_FREEFORM to accept free-form source files.
8622 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
8623 New macros.
8624 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
8625 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
8626 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),

8636 AC_FC_SRCEXT, AC_FC_FREEFORM):
8637 New macros.
8638 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
8639 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
8640 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
8641 Rewrite in terms of the above.
8642 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
8643 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

8645 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
8647 2003-09-02 Paul Eggert <eggert@twinsun.com>
8649 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
8650 Document problems with timestamp resolution that 'make', 'cp -p', and
8651 'touch -r' have.
8653 2003-08-27 Akim Demaille <akim@epita.fr>
8655 * tests/m4sugar.at (cross_warning): Make sure to enable the
8656 output, so that we can track spurious m4sugar output.
8657 * tests/local.at: Require 2.57.
8658 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
8659 are defaulted by AT_CHECK anyway.
8660 Use AT_CHECK_AUTOM4TE.
8661 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
8662 missing dnl.
8664 2003-08-27 Akim Demaille <akim@epita.fr>
8666 * bin/autoheader.in: Issue the "Using auxiliary..." message only
8667 when -Wobsolete is set.
8668 Set it on by default.
8669 Suggested by Klee Dienes.

8706 * Makefile.maint (local-check): Rename as...
8707 (local-checks-available): this.
8708 (local-check): New.
8710 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
8711 * configure.ac: Require Automake 1.7.6.
8713 2003-08-22 Akim Demaille <akim@epita.fr>
8715 Output stack traces in warnings.
8717 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
8718 Replace the former...
8719 (m4_warn): Pass the call stack to _m4_warn.
8720 * bin/autom4te.in: Adjust to output the call stack.
8721 * tests/m4sugar.at (m4@&t@_warn): Adjust.
8723 2003-08-22 Akim Demaille <akim@epita.fr>
8725 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
8726 * bin/autom4te.in: Adjust.
8728 2003-08-21 Akim Demaille <akim@epita.fr>
8730 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
8731 (&verbose): Remove.
8732 (&getopt): Adjust the note and verb channels, depending upon
8733 --verbose.
8734 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
8735 * bin/autoupdate.in: Adjust.
8736 Use &verb, not &verbose.
8738 2003-08-21 Akim Demaille <akim@epita.fr>
8740 * bin/autoheader.in (&parse_args): Use &parse_warnings and
8741 &parse_WARNINGS.
8742 ($help): Use Autom4te::ChannelDefs::usage.
8743 * bin/autoscan.in: Use Autom4te::ChannelDefs.
8744 * lib/Autom4te/General.pm: Don't export error: you don't own it.
8746 2003-08-21 Akim Demaille <akim@epita.fr>
8748 First stab at preserving warnings between calls to autom4te,
8749 including when the cache is used.
8751 There are still several issues: (i) there are too many runs of m4
8752 (one for include, one for warnings, and some more), (ii) warnings
8753 spreading on several lines are not handled gracefully, (iii) the
8754 code meant to have the call stack display for errors does not work
8755 (its handling should move from m4 to autom4te).
8757 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
8758 Use them.
8759 (@preselect): Add m4_warn.
8760 ($exit_status): Remove, use $exit_code.
8761 ($help): Use Autom4te::ChannelDefs::usage.
8762 (&handle_m4): No longer define the m4_warnings.
8763 At each run, extract and report the warnings.
8764 Always cache the result, including if the exit status is on
8765 failure, since if nothing changes, we should result in the same
8766 failure, hence we can use the cache.
8767 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
8768 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
8769 Remove.
8770 (m4_warn): Redefine as a do-nothing: it is its invocation that
8771 matters, as warnings are now reported via traces.
8772 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
8773 the contents of m4_warn: make it _call_ m4_warn, so that tracing
8774 the latter reveals calls to the former.
8776 Adjust the tests.
8778 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
8780 2003-08-21 Akim Demaille <akim@epita.fr>
8782 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
8783 Use them.
8785 2003-08-21 Akim Demaille <akim@epita.fr>
8787 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
8788 forward order.
8789 * lib/Autom4te/ChannelDefs.pm: Doc typos.
8790 (&parse_warnings): Accept a list of warning requests.
8791 (&usage): Return a string, not a side effect.
8792 (cross): New warning category.
8794 2003-08-21 Akim Demaille <akim@epita.fr>
8796 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
8797 (&require_configure_ac): Accept an optional directory argument.
8798 ($configure_ac): Remove.
8799 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
8800 (&catfile): Remove.
8801 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
8802 * bin/autoscan.in: Adjust.
8804 2003-08-20 Akim Demaille <akim@epita.fr>
8806 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
8807 Reported by Alexandre Duret-Lutz.
8809 2003-08-20 Akim Demaille <akim@epita.fr>
8811 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
8812 * bin/autom4te: Adjust.
8813 In particular, be Autoconf tools are really silent when properly
8814 working, bind the verbosity of the 'note' channel to $verbose.
8815 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
8816 (&xsystem, &contents): Remove, since they are exported by...
8817 * lib/Autom4te/FileUtils.pm: this.
8818 More perldoc.
8819 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
8820 * lib/Autom4te/FileUtils.pm: here.
8822 2003-08-20 Akim Demaille <akim@epita.fr>
8824 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
8825 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
8826 from CVS Automake.
8828 2003-08-20 Akim Demaille <akim@epita.fr>
8830 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
8831 (autom4te-update): New.
8832 * Makefile.cfg (update): Bind autom4te-update.
8834 2003-08-19 Derek Price <derek@ximbiot.com>
8836 * lib/autotest/general.m4: Comment various HELP_* diversions.
8837 (PARSE_ARGS_BEGIN): New section for option parsing related
8838 initialization.

8846 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
8848 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
8850 * lib/autom4te.in (Automake-preselections): Preselect
8851 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
8852 and m4_sinclude.
8854 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
8856 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
8857 (Autoconf-without-aclocal-m4): ... this new language.
8858 * doc/autoconf.texi (autom4te Invocation): Mention
8859 Autoconf-without-aclocal-m4.

8864 RUN-IF-PASS optional arguments.

8875 2003-08-14 Derek Price <derek@ximbiot.com>
8877 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
8878 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
8879 shorter column three. Add DESCRIPTION to log file content.
8881 2003-08-13 Derek Price <derek@ximbiot.com>
8883 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
8884 output.
8886 2003-08-12 Derek Price <derek@ximbiot.com>
8888 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
8889 (AT_CHECK_NOESCAPE): Move core functionality to...
8890 (_AT_CHECK): ...this new macro.
8892 2003-08-07 Derek Price <derek@ximbiot.com>
8894 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
8895 (AT_CHECK_NOESCAPE): ...to this new macro.
8897 2003-07-31 Paul Eggert <eggert@twinsun.com>
8899 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
8900 in Bash 2.01. Problem reported by Brian Gough in
8901 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
8903 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
8905 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
8906 -lcrt1.o, for OS X. (trivial change)
8908 2003-07-07 Paul Eggert <eggert@twinsun.com>
8910 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
8911 inside '#ifndef __cplusplus'. Problem reported by
8912 Bob Friesenhahn.
8914 2003-07-06 Bill Clarke <llib@computer.org>
8916 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
8917 'long', not 'int', for benefit of Sun's recent C++ compilers
8918 (trivial change). See:
8919 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
8920 (This really should be 'intptr_t', not 'long', but that would
8921 take more work.)
8923 2003-06-25 Akim Demaille <akim@epita.fr>
8925 * lib/Makefile.am (autom4te.cfg): Make it read only.
8926 Depend on Makefile since it contains substitutions.
8927 From Paolo Bonzini.
8928 * lib/autom4te.in (args): Add local.at? for Autotest args.
8929 This change was made on autom4te.cfg which is generated.
8930 Reported by Raja R. Harinath.
8932 2003-06-25 Akim Demaille <akim@epita.fr>
8934 * doc/autoconf.texi (Header Portability): sys/mount.h.
8935 From Gareth McCaughan.
8937 2003-06-23 Akim Demaille <akim@epita.fr>
8939 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
8940 not all of them. This fixes 1. the fact that when testing
8941 Autoconf there are many many config.log, 2. the incorrect use of
8942 top_srcdir to find config.log.
8943 Don't mix the detailed output of failed test with the summary of
8944 failures. Rather, append detailed log afterwards.
8946 2003-06-23 Akim Demaille <akim@epita.fr>
8948 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
8949 always run: output config.log on $at_group_log.
8951 2003-06-23 Akim Demaille <akim@epita.fr>
8953 * tests/torture.at (#define header templates): Don't use quotes in
8954 C++ comments as it puzzles Emacs' sh font-lock-mode.
8956 2003-06-23 Akim Demaille <akim@epita.fr>
8958 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
8959 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
8960 * tests/atspecific.m4: Rename as...
8961 * tests/local.at: This.
8962 * tests/suite.at: Move the globals into...
8963 * tests/local.at: here.
8964 * tests/Makefile.am: Adjust.
8965 * doc/autoconf.texi (testsuite Scripts): Adjust.
8967 2003-06-21 Kevin Ryde <user42@zip.com.au>
8969 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
8970 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
8971 ensuring we add -std1 for full-ANSI.
8973 * doc/autoconf.texi (hdrindex): New macro.
8974 Add index entries for portability of various standard header files.
8976 2003-06-20 Akim Demaille <akim@epita.fr>
8978 * configure.ac: Bump to 2.57b.
8980 2003-06-20 Akim Demaille <akim@epita.fr>
8982 Version 2.57a.
8984 2003-06-20 Akim Demaille <akim@epita.fr>
8986 * bin/autom4te.in: Don't rely on $HOME being defined.
8987 Reported by Marc Espie as PR/233.
8989 2003-06-20 Akim Demaille <akim@epita.fr>
8991 * lib/autotest/general.m4: Use at_times_file only if used.
8992 From Nicolas Joly.
8994 2003-06-20 Akim Demaille <akim@epita.fr>
8996 * config/config.guess, config/config.sub, config/elisp-comp,
8997 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
8998 Update from masters.
9000 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
9002 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
9003 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
9004 (TEST_SCRIPT): New diversion.
9005 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
9006 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
9007 (AT_INIT): Support for expected failures.
9009 2003-06-02 Akim Demaille <akim@epita.fr>
9011 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
9012 changes.
9013 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
9014 Autoconf nor Automake.
9015 (&contents): New, from Automake.
9016 PODify.
9018 2003-05-28 Paul Eggert <eggert@twinsun.com>
9020 * NEWS, doc/autoconf.texi (Particular Functions),
9021 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
9022 is the inverse of localtime.
9024 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
9026 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
9027 (handle_exec_errors): New function. Work around $! being
9028 altered by WEXITSTATUS.
9029 (xqx, xsystem): Use handle_exec_errors.
9031 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
9033 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
9034 Do not call `_exit()', simply modify `$?'.
9035 (xsystem): Reset $! before running system, and check it afterward.
9036 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
9037 63 for version mismatches.
9039 2003-05-23 Akim Demaille <akim@epita.fr>
9041 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
9042 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
9043 the middle of a line).
9044 * lib/m4sugar/m4sugar.m4: Likewise.
9045 Remove useless spaces in comments.
9047 2003-05-23 Akim Demaille <akim@epita.fr>
9049 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
9050 exit 63, so that we (or Automake's "missing") can tell the
9051 difference with a plain failure.
9052 * doc/autoconf.texi (Notices): Adjust.
9054 2003-05-23 Akim Demaille <akim@epita.fr>
9056 * Makefile.am, bin/Makefile.am, config/Makefile.am,
9057 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
9058 White spaces cleanup.
9060 2003-05-22 Jim Meyering <jim@meyering.net>
9061 Paul Eggert <eggert@twinsun.com>
9063 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
9064 Remove `#include <stdlib.h>' from the list; we should never
9065 make confdefs.h include <stdlib.h> or <cstdlib>, because the
9066 resulting namespace pollution would cause other tests to fail.
9067 Configure scripts run with some older versions of g++ and HP's
9068 aCC would fail due to such an #include. Problems reported by
9069 Matthew Mueller in <http://bugs.debian.org/120704> and by
9070 Keith Bostic in
9071 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
9072 In the test, use the test declaration before including <stdlib.h>,
9073 as that's closer to how it'll be used.
9075 2003-05-23 Akim Demaille <akim@epita.fr>
9077 * doc/autoconf.texi (Header Portability): ucred.h.
9078 From Ian Redfern.
9080 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
9082 Overhaul Autotest's logging: generate separate log files
9083 in testsuite.dir/NNN/testsuite.log, and append them to
9084 testsuite.log instead of re-running the test verbosely.
9086 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
9087 file descriptor, write 0 to at_status_file instead of setting
9088 at_status=0, initialize some new variables (at_status_file,
9089 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
9090 to rerun the tests, instead append the at_group_log to the
9091 at_suite_log when a test fails.
9092 (AT_SETUP): pipe the test case's output into at_tee_pipe,
9093 with the AS_MESSAGE_LOG_FD redirected to stdout.
9094 (AT_CLEANUP): save the output status in $at_status_file
9095 and restore it, redirect the AS_MESSAGE_LOG_FD back to
9096 its original place.
9097 (AT_CHECK): since tests are run with a redirected stdout,
9098 and used to be re-run in verbose mode, turn some $at_verbose
9099 into echo, and don't redirect the output of testing stdout
9100 and stderr.
9102 * lib/autotest/autoconf.texi (testsuite Scripts): Update
9103 the name of the debugging directory and information about
9104 its contents.
9106 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
9108 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
9109 parameter.

9193 user name space clashes.
9194 Reported by Bruno Haible.
9196 2003-05-16 Akim Demaille <akim@epita.fr>

9199 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
9200 them uniform, and more robust to Perl special characters.

9214 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
9215 message.
9216 From Matthias Andree.
9218 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>

9221 and truncate.
9223 2003-05-06 Akim Demaille <akim@epita.fr>
9225 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
9226 longer updates aclocal.m4 if useless, (ii) if a file m4_included
9227 by aclocal.m4 is changed it might require the importing of another
9228 m4 extension file, i.e., aclocal must be run.
9230 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
9231 (&parse_args): Use --force with aclocal if required and supported.
9232 (&autoreconf_current_directory): Use &run_aclocal.
9234 2003-05-06 Akim Demaille <akim@epita.fr>
9236 Lock autom4te's cache.
9238 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
9239 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
9240 argument instead of a file name, so that the request file remains
9241 open during the whole autom4te run.
9242 ($icache_file): New.
9243 (&freeze): Lock the $icache_file.
9245 2003-04-29 Derek Price <derek@ximbiot.com>
9247 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
9248 seperator with m4_append_uniq(). It doesn't work.
9249 (AT_CLEANUP): Add `;' to end of at_help_all.
9250 (AT_INIT): Allow --keywords to be specified more than once. When
9251 grepping $at_help_all for keywords, use the field and keyword
9252 seperators to ensure a complete keyword match. Alter at_prev handling
9253 to support the new --keywords behavior.
9255 2003-04-27 Karl Berry <karl@freefriends.org>
9257 * doc/autoconf.texi: Make the dir entries in the autoconf manual
9258 align better with others. I also made some of the individual
9259 entries on one line, for brevity and to make it easier for me to
9260 sort my dir-example file in the Texinfo distribution :).
9262 2003-04-12 Jim Meyering <jim@meyering.net>

9277 * GNUmakefile (SHELL): Don't assume sh is in /bin/.
9278 From Ilya Zakharevich.
9280 2003-04-08 Akim Demaille <akim@epita.fr>
9282 * doc/autoconf.texi (Particular Headers): Some about sys/socket.h,
9283 net/if.h, stdlib.h.

9302 * doc/Makefile.am (CLEANFILES): Adjust.
9303 (TEXI2DVI): Make it --batch.
9305 2003-03-31 Derek Price <derek@ximbiot.com>
9307 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
9308 which removed the main loop.
9309 Thanks to Akim Demaille.
9311 2003-03-29 Akim Demaille <akim@epita.fr>

9327 header causes problems.
9329 2003-03-28 Akim Demaille <akim@epita.fr>
9331 * tests/torture.at (Configuring subdirectories): Require aclocal
9332 1.4, otherwise the test fails, as it does support configure.ac.
9333 This fixes the "test 40 failed" bug reports.
9335 2003-03-28 Akim Demaille <akim@epita.fr>
9337 * doc/autoconf.texi (C Compiler): `#line' portability.
9338 From Paul Eggert and Nelson H. F. Beebe.
9340 2003-03-27 Derek Price <derek@ximbiot.com>
9342 * lib/autotest/general.m4: Eliminate main loop and reorganize test
9343 layout in order to allow scripting around test groups.
9345 2003-03-27 Derek Price <derek@ximbiot.com>
9347 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
9348 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
9349 use new diversions in preparation for accepting new arguments and

9353 2003-03-26 Derek Price <derek@ximbiot.com>
9355 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
9356 obsolete AC_HELP_STRING.
9357 (AC_HELP_STRING): AU_DEFUN to...
9358 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
9359 * tests/m4sh.at (AS_HELP_STRING): New test.
9361 * tests/acgeneral.at: Regenerated.
9363 2003-03-26 Derek Price <derek@ximbiot.com>
9365 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
9366 sense. Verbosify the diversion definitions comment.
9368 2003-03-26 Derek Price <derek@ximbiot.com>
9370 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
9371 AS_PREPARE.

9405 Tru64 make in the "target lookup" section.
9406 (Automake): Automake 1.5+ no longer requires special tools to be
9407 present on the developer's host.

9415 * bin/autom4te.in (BEGIN): Likewise.
9416 * bin/autoreconf.in (BEGIN): Likewise.
9417 * bin/autoscan.in (BEGIN): Likewise.
9418 * bin/autoupdate.in (BEGIN): Likewise.

9423 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
9424 to cope with DOS-style absolute paths, when constructing
9425 ${ac_make}.
9427 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
9428 When constructing paths with IFS=:, quote the path. If we're
9429 constructing a DOS-style absolute path, we don't want to split it
9430 on the colon.
9432 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
9433 in description.
9435 2003-02-25 Pavel Roskin <proski@gnu.org>

9443 2002-09-01 patch by replacing "test -n" with "test -z".
9444 This fixes a bug found by Jeff Painter and reported by Tom Epperly in

9447 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
9448 to fix a mismatch between example and discussion.
9450 2003-02-24 Kevin Ryde <user42@zip.com.au>
9452 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
9453 format starting with "-".
9455 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9457 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
9458 is not portable inside Makefile.
9460 2003-02-20 Akim Demaille <akim@epita.fr>
9462 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
9463 compiler says yeah, but preproc says nope, compiler is right.
9464 Conversely, prompt the reader to send a bug report to the
9465 maintainers of the package, not of Autoconf.
9467 2003-02-20 Klee Dienes <kdienes@apple.com>
9469 * bin/autoreconf.in (autoreconf_current_directory): Properly
9470 handle an empty aclocal.m4.

9480 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
9481 innocuous variant befor including <limits.h> or <assert.h>. This
9482 works around a bug reported by Albert Chin: HP-UX 11i
9483 (and earlier versions) have a <limits.h> that declares
9484 gettimeofday and many other functions.
9486 2002-12-03 Paul Eggert <eggert@twinsun.com>
9488 Version 2.57.
9490 * NEWS, configure.ac: Update version.
9492 * doc/fdl.texi: Upgrade to FDL version 1.2.
9494 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
9495 nontrivially in main's body, so that f's external declaration is
9496 not optimized away in AIX. This should fix the bug reported by
9497 Martin Frydl in
9498 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
9500 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
9501 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
9502 defined, to support freestanding compilers. This should fix the
9503 bug reported by Momchil Velkov in
9504 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
9506 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
9507 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
9508 obsolete AC_CHECK_TYPE. The missing empty arg was reported
9509 by Simon Josefsson in

9512 * Makefile.maint (www-gnu): New macro.
9513 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
9514 the location has moved.
9516 2002-12-02 Martin Frydl <martin@systinet.com>
9518 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
9519 \(.*\) match is too long and there is something more to be checked.
9520 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
9522 2002-11-15 Akim Demaille <akim@epita.fr>
9524 Version 2.56.
9526 * config/install-sh: chmod +x.
9527 From Paul Eggert.
9528 * config/move-if-change: Indenting changes.
9529 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
9530 * configure.ac (AM_INIT_AUTOMAKE): here.
9531 Require 1.7.1.
9533 2002-11-14 Akim Demaille <akim@epita.fr>
9535 Version 2.55.
9537 * config/config.guess, config/config.sub, config/install-sh:
9538 Update from masters.
9540 2002-11-14 Akim Demaille <akim@epita.fr>
9542 * Makefile.maint: Sync with Bison, i.e.:
9543 (po-check): Scan .l and .y files instead of the
9544 .c and the .h files that they generate. This fixes the bug
9545 reported by Tim Van Holder in:
9546 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
9547 Look for N_ as well as for _. Try to avoid matching #define for
9548 N_ and _.
9549 From Paul Eggert.
9551 2002-11-14 Akim Demaille <akim@epita.fr>
9553 * doc/autoconf.texi (C Compiler): Compiling several files at once.
9554 From Paul Eggert and Albert Chin-A-Young.
9556 2002-11-14 Akim Demaille <akim@epita.fr>
9558 * doc/autoconf.texi (C Compiler): Solitary backslashes.
9559 From Paul Eggert and Albert Chin-A-Young.
9561 2002-11-14 Kevin Ryde <user42@zip.com.au>
9563 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
9564 than assigning in main, to avoid HP cc +O3 optimizing it away.
9566 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
9568 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
9569 option. Process --recheck after parsing all options. Pass -q
9570 option to configure on --recheck.
9571 (AC_OUTPUT): Pass -q from configure to config.status.
9572 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
9573 arguments to record.
9574 * doc/autoconf.texi (config.status Invocation): Document
9575 config.status -q option.
9577 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
9579 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
9580 Makefile.in if Makefile.am exists.
9581 (output): Strip `.am' from Makefiles. Don't
9582 output AC_CONFIG_FILES if no Makefiles were found.
9584 2002-11-07 Akim Demaille <akim@epita.fr>
9586 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
9587 (local_updates): New.
9588 * Makefile.maint: Update, from CVS Bison.
9589 (local_updates): New.
9591 2002-11-06 Akim Demaille <akim@epita.fr>
9593 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
9594 declaration in extern "C" too.
9595 Reported by Roberto Bagnara.
9597 2002-11-06 Akim Demaille <akim@epita.fr>
9599 * tests/torture.at (Configuring subdirectories): Don't use grep
9600 -w.
9601 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
9602 Reported by Ezra Peisach.
9604 2002-11-05 Akim Demaille <akim@epita.fr>
9606 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
9607 Remove.
9608 We _have_ to stop using the old compatibility scheme that tried to
9609 avoid useless backslashes because Libtool 1.4.3 contains a
9610 AC_DEFINE([error_t], [int],
9611 [Define to a type to use for \`error_t' if it is not
9612 otherwise available.])
9613 We _have_ to quote the single quote and backslashes with \. The
9614 old compatibility scheme saw that ` was backslashed, and therefore
9615 did not quote the single quote. Hence before this patch, Autoconf
9616 was not compatible with Libtool.
9618 2002-11-04 Paul Eggert <eggert@twinsun.com>
9620 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
9621 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
9622 LC_NAME, LC_PAPER, LC_TELEPHONE.
9623 * doc/autoconf.texi (Special Shell Variables): Mention those vars.
9625 2002-11-04 Akim Demaille <akim@epita.fr>
9627 Version 2.54c.
9629 * Makefile.maint (update, cvs-update, po-update, do-po-update):
9630 New.
9631 * config/texinfo.tex: Update.
9633 2002-11-03 Akim Demaille <akim@epita.fr>
9635 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
9636 from...
9637 (&autoreconf): here.
9638 ($help, $make, &parse_args, &autoreconf_current_directory):
9639 Support -m/--make.
9640 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9642 2002-10-31 Bruno Haible <bruno@clisp.org>
9644 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.
9645 Change name of cache variable to ac_cv_func_malloc_0_nonnull.
9646 (AC_FUNC_MALLOC): Change description of HAVE_MALLOC macro.

9648 to ac_cv_func_realloc_0_nonnull.
9649 (AC_FUNC_REALLOC): Change description of HAVE_REALLOC macro.
9651 2002-10-31 Akim Demaille <akim@epita.fr>
9653 The test suite was no longer checking for trailing envvars and files.
9655 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
9656 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
9658 2002-10-31 Akim Demaille <akim@epita.fr>

9948 2002-10-22 Akim Demaille <akim@epita.fr>

10007 Reported by Alexandre Duret-Lutz.
10009 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

10013 (&freeze): Use &error.
10014 (&up_to_date): If a file that was included according to the cache
10015 is no longer there, then the output is out dated.

10024 * bin/autoreconf.in (&parse_args): Remove dead options.
10025 Factor some code.
10026 (&autoreconf): Report the directories we enter *and leave*, so
10027 that error messages can be easily located, and use GNU Make
10028 format, so that Emacs' compile mode understands us.
10029 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
10030 if some file was changed instead of `print'.
10031 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

10064 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the

10066 From Sam Varshavchik.
10068 2002-10-08 Akim Demaille <akim@epita.fr>
10070 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
10071 aclocal invocation, as Gettext macros might not be visible to
10072 aclocal.
10073 Instead of blindly running autopoint, scan configure.ac (not the
10074 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
10075 Reported by Paul D. Smith.
10077 2002-10-08 Paul Eggert <eggert@twinsun.com>
10079 Work around problems found when POSIXLY_CORRECT=1 is set.
10080 None of this seems to have anything to do with POSIX, really,
10081 but it's how Perl getopt works.
10082 * bin/autom4te.in (parse_args): Configure GetOpt with
10083 "permute", too.
10084 * doc/autoconf.texi (Invoking autom4te):

10105 2002-09-28 Akim Demaille <akim@epita.fr>
10107 * tests/torture.at (Configuring subdirectories): Be robust to
10108 users who use config.site to require for a cache: in this case,
10109 the two last configure runs, using two different sets of
10110 arguments, trigger a legitimate error.
10112 2002-09-28 Akim Demaille <akim@epita.fr>
10114 * tests/m4sh.at (Functions Support, Functions and return Support):
10115 New.

10128 (tm_zone): Move their rules to...
10129 * lib/autoconf/types.m4: here, using AN_ macros.
10130 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
10131 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)

10145 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
10146 (.m4.m4f): Don't pass --prepend-include, since that's done by
10147 tests/autom4te itself.
10148 * lib/autoscan/Makefile.am: Include freeze.mk.
10149 (autoscan.list): New target --this file is no longer a source.

10165 * lib/autoscan/autoscan.list: this.
10166 * bin/autoscan.in (&init_tables): Adjust.
10168 2002-09-28 Akim Demaille <akim@epita.fr>
10170 * lib/autoscan/functions, lib/autoscan/headers,
10171 * lib/autoscan/identifiers, lib/autoscan/makevars,
10172 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
10173 `functions' line is now prefixed with `function:'.
10174 * bin/autoscan.in (&init_tables): Adjust.
10176 2002-09-28 Akim Demaille <akim@epita.fr>
10178 From now on, autoscan files must always map a macro name to a
10179 word: there is no `default' macro for autoscan.
10181 * bin/autoscan.in (&init_tables): Reject entries with no macro at
10182 all.
10183 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
10184 explicit.
10186 2002-09-28 Akim Demaille <akim@epita.fr>
10188 * bin/autoscan.in (%c_keywords): Remove.

10190 (&output_kind): It is no longer needed to look for non active
10191 checks.
10193 2002-09-27 Akim Demaille <akim@epita.fr>
10195 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
10196 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
10197 * lib/autoscan/functions: Adjust.

10200 2002-09-27 Akim Demaille <akim@epita.fr>
10202 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
10203 from /tmp.
10204 Thanks to Bill Moseley and Paul Eggert.
10205 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
10206 the tmpdir must be created.
10207 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp

10221 Reported by Ralf Corsepius.
10222 * doc/autoconf.texi (autoreconf Invocation): Likewise.
10224 2002-09-26 Akim Demaille <akim@epita.fr>
10226 Single suffix rules and seperated dependencies are not portable.
10228 * doc/autoconf.texi (Installation Directory Variables): Update.
10229 (Limitations of Make): Some about `Single Suffix Rules and
10230 Separated Dependencies'.
10231 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10232 (ifnames, autoscan, autom4te): Un-factor into several rules.
10234 2002-09-25 Paul Eggert <eggert@twinsun.com>
10236 * BUGS (Interoperability bugs): New section. Mention libtool
10237 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
10239 2002-09-24 Paul Eggert <eggert@twinsun.com>
10241 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
10242 make handles suffix-rules differently from GNU make.
10244 * bin/Makefile.am (SUFFIXES, .in): Remove.
10245 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
10246 Move the body of the old .in rule here.
10248 2002-09-16 Akim Demaille <akim@epita.fr>
10250 i960 compilers create `b.out' files by default.
10251 Reported by Ralf Corsepius.
10253 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
10254 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
10256 2002-09-13 Paul Eggert <eggert@twinsun.com>
10258 * doc/autoconf.texi (Particular Headers): Remove obsolete
10259 reference to `struct timezone' in the description of
10260 AC_HEADER_TIME.
10262 2002-09-13 Akim Demaille <akim@epita.fr>
10264 Version 2.54.
10266 * config/config.sub, config/config.guess: Update.
10267 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
10268 * Makefile.am: Adjust.
10270 2002-09-13 Akim Demaille <akim@epita.fr>
10272 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
10273 reading config.log when the compiler is rejected.
10274 Suggested by Guido Draheim.
10276 2002-09-13 Akim Demaille <akim@epita.fr>
10278 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
10279 (chdir_init) might hang when stat'ing mounted directories.
10280 Reported by Vance Shipley.
10282 2002-09-12 Akim Demaille <akim@epita.fr>
10284 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
10285 the lists.
10287 2002-09-12 Akim Demaille <akim@epita.fr>
10289 * doc/autoconf.texi (Defining Symbols): Present two different
10290 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
10291 difference between 1 argument calls, and 2-3 argument calls.
10293 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
10295 * doc/autoconf.texi: Review grammar and punctuation.
10297 2002-09-11 Paul Eggert <eggert@twinsun.com>
10299 * doc/autoconf.texi: Fix minor formatting, spelling, and
10300 grammatical typos.
10301 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
10302 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
10303 is obsolescent.
10305 2002-09-11 Akim Demaille <akim@epita.fr>
10307 * doc/autoconf.texi (Questions): Rename as...
10308 (FAQ): this.
10309 (Defining Directories): New.
10311 2002-09-09 Akim Demaille <akim@epita.fr>
10313 * doc/autoconf.texi (Making testsuite Scripts): Update.
10314 Suggested by Nishio Futoshi.
10316 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
10318 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
10319 plain `@' is wanted.
10321 2002-09-09 Akim Demaille <akim@epita.fr>
10323 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
10324 `duplicates', since the algorithm was too naive and could keep
10325 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
10326 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
10327 Reported by Ralf Corsepius.
10328 * tests/torture.at (Configuring subdirectories): Exercise these
10329 cases.
10331 2002-09-09 Akim Demaille <akim@epita.fr>
10333 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
10334 looking for a replacement file.
10335 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
10336 directory is relative.
10337 * doc/autoconf.texi (Generic Functions): Clarify the replacement
10338 directory definition.
10339 Reported by Andreas Schwab and Jim Meyering.
10341 2002-09-06 Akim Demaille <akim@epita.fr>
10343 * doc/autoconf.texi (Setting Output Variables): Clarify what
10344 precious variables are.
10345 Suggested by Pontus Skoeld.
10347 2002-09-05 Akim Demaille <akim@epita.fr>
10349 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10350 (ifnames, autoscan, autom4te): Since we don't only depend on
10351 configure.ac variables (such as VERSION etc.), but also on prefix
10352 and so forth, depend on Makefile, not configure.ac.
10353 Reported by Alexandre Duret-Lutz.
10354 * doc/autoconf.texi (Installation Directory Variables): Adjust.
10356 2002-09-05 Kevin Ryde <user42@zip.com.au>
10358 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
10359 doesn't seem to be confined to ia64, just say "some versions".
10361 2002-09-04 Akim Demaille <akim@epita.fr>
10363 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
10364 Automake 1.6c.
10365 * Makefile.am (maintainer-clean-local): Remove.
10366 (MAINTAINERCLEANFILES): Remove COPYING.
10368 2002-09-03 Paul Eggert <eggert@twinsun.com>
10370 * doc/autoconf.texi (Configuration Commands): Remove obsolete
10371 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
10372 Brinkmann.
10374 2002-09-03 Akim Demaille <akim@epita.fr>
10376 * configure.ac: Bump to 2.53d.
10377 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
10378 as of today, on Automake's team suggestion.
10380 2002-09-03 Akim Demaille <akim@epita.fr>
10382 Version 2.53c.
10384 2002-09-02 Akim Demaille <akim@epita.fr>
10386 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
10387 SITE_MACRO_DIR.
10388 * configure.ac: Disable SITE_MACRO_DIR.
10390 2002-09-02 Jim Meyering <meyering@lucent.com>
10392 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
10393 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
10394 Also, tweak grammar: s/make sure to/be sure to/.
10396 2002-09-02 Paul Eggert <eggert@twinsun.com>
10398 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
10399 directory names are generally preferable to physical names.
10401 2002-09-02 Akim Demaille <akim@epita.fr>
10403 * lib/Autom4te/General.pm (&update_file): s/die/error/.
10404 Reported by Raja R. Harinath.
10405 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
10406 * bin/autoupdate.in: Use error instead of die.
10408 2002-09-01 Paul Eggert <eggert@twinsun.com>
10410 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
10411 ordinary shell concatenation rather than echo+tr+sed command that
10412 runs afoul of a long-line-related sed bug in Solaris 8.
10414 * bin/autoheader.in (parse_args): --warning -> --warnings.
10416 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
10417 stdout, as traditional "ls" does.
10418 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
10419 _AC_COMPILER_EXEEXT_O): Likewise.
10420 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
10422 * bin/autoconf.as: Add --prepend-include option. This patch was
10423 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
10424 but bin/autoconf.in is generated automatically from bin/autoconf.as.
10426 * bin/autoconf.in, configure: Regenerate.
10428 * doc/autoconf.texi (Special Shell Variables): Mention
10429 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
10431 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
10432 MAILPATH and set PS1, PS2, PS4 to default values, to work
10433 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
10434 For LC_ALL etc, first try to set to "C" as POSIX requires and as
10435 the Autoconf documentation specifies; fall back to "unset" only if
10436 this fails. Use a shell for-loop for this rather than an m4 loop,
10437 to shorten the output script.
10439 2002-08-30 Paul Eggert <eggert@twinsun.com>
10441 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
10442 1003.1-2001's requirements for CDPATH. Give a simpler workaround
10443 for the CDPATH problem. Document PWD.
10444 (Limitations of Builtins): Document the problem that "cd $foo" and
10445 "ls $foo" may refer to different directories in shells conforming
10446 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
10447 example, since the old example is now out of date.
10449 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
10450 FOO" and "ls FOO" talk about different directories; this catches
10451 problems when POSIX 1003.1-2001 "cd" fails due to symlink
10452 spaghetti.
10454 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
10455 of rolling our own unset.
10456 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
10457 in practice we needn't worry about CDPATH if unset doesn't work.
10459 * Makefile.in, aclocal.m4, bin/Makefile.in,
10460 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
10461 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
10462 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
10463 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
10464 tests/Makefile.in: Regenerate with Automake 1.6.3.
10466 * config/config.guess, config/config.sub, config/mkinstalldirs:
10467 Update.
10469 * configure: Regenerate with self.
10471 2002-08-30 Kevin Ryde <user42@zip.com.au>
10473 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
10474 default output.
10476 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
10478 * bin/autom4te.in (Request::load): Correctly test for "do" read
10479 failure.
10481 2002-08-29 Akim Demaille <akim@epita.fr>
10483 * lib/Autom4te/General.pm (&xqx): New.
10484 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
10485 hand, which is not portable.
10486 (&error): New.
10487 * bin/autom4te.in: Use them.
10488 Use &error instead of die.
10489 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
10490 Adjust.
10492 2002-08-17 Paul Eggert <eggert@twinsun.com>
10494 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
10495 default list of compilers to try, since it was long ago superseded
10496 by the ksh fc builtin. Suggested by Steven G. Johnson.
10498 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
10500 * doc/autoconf.texi (Invoking autom4te): End the option table,
10501 fixing a bug introduced by the previous patch.
10502 (Limitations of Make): Add a 'target lookup' subentry in the
10503 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
10505 2002-07-29 Mark D. Roth <roth@feep.net>
10507 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
10508 options and use $AUTOM4TE_PATH.
10509 * doc/autoconf.texi: Remove documentation of autom4te
10510 --include-envvar and --site-macro-subdir options and document
10511 use of $AUTOM4TE_PATH.
10512 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
10513 arguments from each language section.
10515 2002-07-29 Paul Eggert <eggert@twinsun.com>
10517 * doc/install.texi: Include copyright symbol in copyright notice.
10519 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
10520 Replace with:
10521 (AM_MAKEINFOFLAGS): New macro.
10522 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
10523 * Makefile.am (INSTALL): Use the new macros.
10524 Use -o rather than --output, since "missing" does not grok --output.
10526 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10528 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
10529 comments do not always work. Never trust the exit status of
10530 `make -k'.
10532 2002-07-24 Kevin Ryde <user42@zip.com.au>
10534 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
10535 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
10537 2002-07-23 Paul Eggert <eggert@twinsun.com>
10539 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
10540 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
10541 apparently treats PATH="nonexistent" as if it contained ".".
10542 Bug reported by Stefan `Sec' Zehl.
10544 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10546 * doc/autoconf.texi (Limitations of Make): Mention the special
10547 handling of the obj/ directory by BSD make.
10549 2002-07-20 Kevin Ryde <user42@zip.com.au>

10552 backslashes.
10554 2002-07-19 Akim Demaille <akim@epita.fr>

10557 (Programming in M4sh): Ethymology of M4sh.
10559 2002-07-19 Akim Demaille <akim@epita.fr>
10561 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
10563 2002-07-18 Akim Demaille <akim@epita.fr>
10565 Version 2.53b.
10567 2002-07-18 Akim Demaille <akim@epita.fr>
10569 * config/config.guess, config/config.sub: Update.
10571 2002-07-18 Akim Demaille <akim@epita.fr>
10573 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
10574 Automake's parts.
10576 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
10577 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
10578 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
10580 2002-07-18 Akim Demaille <akim@epita.fr>,
10581 Alexandre Duret-Lutz <duret_g@epita.fr>
10583 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
10584 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
10586 2002-07-17 Russ Allbery <rra@stanford.edu>
10588 * doc/autoconf.texi (Initializing configure): Clarify the
10589 description of the tarname default.
10591 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
10593 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
10594 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
10595 latter was not run.
10597 2002-07-17 Akim Demaille <akim@epita.fr>
10599 * lib/Autom4te/General.pm (find_file): Browse the directories in
10600 the order they are given.
10602 2002-07-17 Akim Demaille <akim@epita.fr>
10604 * tests/wrapsh.as, tests/wrappl.as: Merge into...
10605 * tests/wrapper.as: this.
10606 * tests/Makefile.am, configure.ac: Adjust.
10608 2002-07-17 Mark D. Roth <roth@feep.net>
10610 * configure.ac: Add --enable-site-macro-dir option.
10611 * bin/Makefile.am: Expand @SITE_MACRO_DIR@.
10612 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
10613 --site-macro-subdir options.
10614 * bin/autoconf.in: Add --prepend-include option.
10615 * bin/autoheader.in: Add --prepend-include option.
10616 * bin/autoreconf.in: Add --prepend-include option.

10680 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
10681 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
10682 so that we consistently test the just-built programs.
10683 * tests/wrappl.as: Likewise.
10685 2002-06-12 Paul Eggert <eggert@twinsun.com>

10703 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
10705 * bin/autom4te.in ($cache): Don't define using `$me', the name
10706 of the cache should not depend on the name under which autom4te
10707 was installed.
10709 2002-06-07 Akim Demaille <akim@epita.fr>

10726 AC_FUNC_FNMATCH_GNU.
10728 2002-06-07 Akim Demaille <akim@epita.fr>

10733 2002-06-07 Akim Demaille <akim@epita.fr>
10735 * bin/autom4te.in (warn_forbidden): When rejecting a token,
10736 suggest m4_pattern_allow.
10737 Suggested by Adam J. Richter.
10739 2002-06-07 Akim Demaille <akim@epita.fr>
10741 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
10742 ac_config_libobj_dir.
10743 (AC_CONFIG_LIBOBJ_DIR): New.
10744 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

10791 * NEWS, doc/autoconf.texi (Particular Types): Document it.
10792 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it

10800 2002-05-22 Paul Eggert <eggert@twinsun.com>
10802 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
10803 from the default list of compilers to try. Suggested by
10804 Kate Hedstrom.
10805 * NEWS: Document the above.
10806 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
10808 2002-05-17 Paul Eggert <eggert@twinsun.com>
10810 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
10811 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
10812 This improves on an earlier suggestion by H. Peter Anvin.
10814 2002-05-16 Paul Eggert <eggert@twinsun.com>
10816 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
10817 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
10818 Both macros now accept an optional source-dir arg.
10819 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
10821 * NEWS: Document this.
10822 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
10824 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
10825 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
10826 not for GNU extensions; this undoes part of the 2000-11-03 change,
10827 reverting to 2.13-compatible behavior.
10828 Add new optional argument DIR.
10829 (AC_FUNC_FNMATCH_GNU): New macro.
10831 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
10833 2002-05-08 Paul Eggert <eggert@twinsun.com>
10835 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
10836 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
10837 and it causes a 'test' syntax error if it fails.
10838 Bug reported by Stephen Gildea.
10840 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
10841 If prototypes are supported, use them to check this at compile-time,
10842 instead of trying to check it at run-time. If we must do a run-time
10843 check, assume that setvbuf is standard when cross-compiling, as
10844 nonstandard setvbuf occurs only on ancient and unlikely hosts.
10845 Bug reported by Paul D. Smith.
10847 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
10848 argument specifying location of getloadavg.c. This removes a
10849 FIXME. This idea was taken from Jim Meyering's implementation in
10850 textutils.
10851 * doc/autoconf.texi (Particular Functions): Document this.
10852 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
10853 that's what the code does; this fixes a bug reported by
10854 Paul D. Smith.
10856 2002-05-03 Akim Demaille <akim@epita.fr>
10858 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
10859 autopoint instead of gettextize.
10860 ($uses_alocal): Rename as...
10861 ($uses_aclocal): this.
10862 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10863 Suggested by Bruno Haible.
10865 2002-05-03 Akim Demaille <akim@epita.fr>
10867 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
10869 2002-04-29 Paul Eggert <eggert@twinsun.com>
10871 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
10872 files to be 1 second older; just set them to be the same time.
10873 Also, sleep 1 second after the first aclocal, to work around
10874 problems with sub-second time stamps on the input files.
10876 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
10878 * doc/autoconf.texi: Mention "set -e -x" lossage
10879 under node "Limitations of Builtins".
10881 2002-04-29 Akim Demaille <akim@epita.fr>
10883 * doc/install.texi: Better wording for setting variables when
10884 running configure.
10885 From Christian Cornelssen.
10887 2002-04-29 Akim Demaille <akim@epita.fr>
10889 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
10890 of lack of $LINENO support, then the test will compare the $LINENO
10891 in testsuite vs. the lineno in the test file. This is wrong, of
10892 course.
10893 Be sure to protect it.
10894 Reported by Patrick Welche.
10896 2002-04-25 Akim Demaille <akim@epita.fr>
10898 * doc/autoconf.texi (Obsolete Macros): Typo.
10899 Reported by Vladimir Volovich.
10901 2002-04-25 Akim Demaille <akim@epita.fr>
10903 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
10904 than some of the input files, hence, on the second run of aclocal,
10905 if some of its input are younger, make them older.
10906 Suggested by Paul Eggert.
10908 2002-04-25 Akim Demaille <akim@epita.fr>
10910 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
10911 Thanks to Paul Eggert.
10913 2002-04-25 Akim Demaille <akim@epita.fr>
10915 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
10916 and ac_subst_vars be sh variables containing the list of
10917 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
10918 DEFAULT diversion.
10919 (_AC_INIT_PREPARE): Use them to log them.
10920 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
10921 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
10922 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
10923 _AC_SUBST_FILES and _AC_SUBST_VARS.
10924 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
10926 2002-04-24 Akim Demaille <akim@epita.fr>
10928 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
10929 autoheader, so that automake does not complain about a missing
10930 config.h.in that was to be created.
10932 2002-04-23 Akim Demaille <akim@epita.fr>
10934 * bin/autoheader.in (parse_args): --warning takes an argument.
10935 Fixes PR/220.
10937 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
10939 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
10940 and bb.out when cleaning up.

10956 2002-04-22 Akim Demaille <akim@epita.fr>
10958 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
10959 Fixes false failures on Darwin.

10984 Minor spelling and grammar fixes.
10986 * doc/autoconf.texi: Follow the outline suggested in the GNU
10987 Sample Texts sections of the Texinfo 4.2 manual. Most
10988 importantly, this makes sure that the copyright notices appear in
10989 all output formats. You probably need Texinfo 4.2 to generate
10990 the manual now.

11041 Adjust Autoconf and Autotest.

11044 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
11045 * lib/autotest/general.m4 (AT_INIT): Likewise.
11046 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

11086 2002-04-03 Akim Demaille <akim@epita.fr>
11088 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
11089 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
11090 Use dnl, not the KILL diversion.
11091 Extracted from...
11092 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
11093 (AC_CONFIG_LINKS): here.
11094 Adjust.
11095 Don't use the KILL diversion, as it kills spurious output, which
11096 results in failures being hidden.
11097 Use m4_defn where appropriate.
11098 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
11099 after the second argument.
11100 Use m4_defn.
11101 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
11102 syntax, as it is provided by M4sugar.
11103 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
11105 2002-04-03 Andreas Schwab <schwab@suse.de>
11107 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
11108 expanded if $# <= 2.
11110 * bin/autoreconf.in (autoreconf): Run automake after rerunning
11111 aclocal.
11113 2002-04-03 Akim Demaille <akim@epita.fr>
11115 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
11116 (_AC_COMPILER_EXEEXT_REJECT): New.
11117 Also recognize *.bb and *.bbg as compilation byproducts.
11118 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
11119 (_AC_COMPILER_OBJEXT): Use them.
11120 Fixes Debian #138666.
11122 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
11124 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
11126 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
11127 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
11128 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
11129 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
11130 (AC_C_CONST): Same.
11131 (AC_C_INLINE): Same.
11132 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
11133 * doc/autoconf.texi, NEWS: Document.
11134 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
11135 AC_C_CROSS.
11137 2002-04-02 Akim Demaille <akim@epita.fr>
11139 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
11140 _AS_MKDIR_P_PREPARE.
11142 2002-03-28 Kevin Ryde <user42@zip.com.au>
11144 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
11145 to avoid versions of HP C which don't allow that.
11147 2002-03-27 Paul Eggert <eggert@twinsun.com>
11149 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
11150 (AS_SHELL_SANITIZE): Invoke it.
11151 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
11153 2002-03-26 Akim Demaille <akim@epita.fr>
11155 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
11157 2002-03-26 Akim Demaille <akim@epita.fr>
11159 * doc/autoconf.texi (Introduction): The GNATS base moved.
11161 2002-03-25 Paul Eggert <eggert@twinsun.com>
11163 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
11164 as POSIX requires, as it doesn't work with Zsh.
11165 * doc/autoconf.texi (Assignments): Document the problem.
11167 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11169 * doc/autoconf.texi (Limitations of Make): Mention more issue
11170 about VPATH, overriding of macros in sub-makes, and handling of
11171 SHELL.
11173 2002-03-21 Paul Eggert <eggert@twinsun.com>
11175 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
11176 problem with here-document buffer boundaries.
11178 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
11179 when reinvoking the shell, to work around problems with installers
11180 who put strange things like "cd" commands in their environments.
11182 2002-03-19 Akim Demaille <akim@epita.fr>
11184 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
11185 From Aaron Ucko.
11187 2002-03-19 Akim Demaille <akim@epita.fr>
11189 * bin/autoscan.in (scan_file): Specify the location in `&used'
11190 invocations.
11191 From Nicolas Joly.
11193 2002-03-19 Akim Demaille <akim@epita.fr>
11195 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
11196 From Nishio Futoshi.
11198 2002-03-19 Akim Demaille <akim@epita.fr>
11200 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
11202 2002-03-18 Paul Eggert <eggert@twinsun.com>
11204 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
11205 (Limitations of Usual Tools): Add mkdir section.
11207 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
11208 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
11209 back on AS_DIRNAME to compute prefixes otherwise; this is
11210 roughly what mkinstalldirs does. That way, we need not have
11211 our own filename disassembler. The old disassembler did not
11212 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
11214 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
11215 Create at_test_all by a series of assignments,
11216 not by a single assignment of a long string. The latter causes ksh
11217 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
11218 presumably because of a buffer overrun.
11220 2002-03-14 Paul Eggert <eggert@twinsun.com>
11222 * lib/autotest/general.m4 (at_times_skip):
11223 Renamed from at_times. Now a boolean.
11224 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
11225 says 'times: not found'.
11227 2002-03-14 Akim Demaille <akim@epita.fr>
11229 * bin/autoreconf.in (&study_gettextize): New.
11230 (&autoreconf): Handle newest gettextize.
11231 Rerun aclocal if needed.
11232 Suggested by Andreas Schwab.
11234 2002-03-13 Akim Demaille <akim@epita.fr>
11236 * doc/autoconf.texi (Special Shell Variables): More about IFS.
11238 2002-03-13 Akim Demaille <akim@epita.fr>
11240 * doc/autoconf.texi (Header Portability): New.
11241 Add information about stdint.h and inttypes.h from Paul Eggert.
11243 2002-03-13 Akim Demaille <akim@epita.fr>
11245 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
11246 -p'.
11247 From Bob Proulx.
11249 2002-03-12 Akim Demaille <akim@epita.fr>
11251 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
11252 m4_require.
11254 2002-03-11 Andreas Schwab <schwab@suse.de>
11256 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
11257 does not do it if --with-lispdir is given.
11259 2002-03-08 Akim Demaille <akim@epita.fr>
11261 Version 2.53.
11263 2002-03-08 Akim Demaille <akim@epita.fr>
11265 * doc/autoconf.texi (Subdirectories): Clarify that the
11266 subdirectory should exist.
11268 2002-03-08 Akim Demaille <akim@epita.fr>
11270 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
11272 2002-03-08 Akim Demaille <akim@epita.fr>
11274 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
11275 aliases the actual variables, and modifications of the former
11276 affect the latter.
11278 2002-03-08 Akim Demaille <akim@epita.fr>
11280 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
11281 because of C-c: have m4 output in tmp files, then mv them.
11283 2002-03-08 Akim Demaille <akim@epita.fr>
11285 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
11286 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
11287 * bin/ifnames.in: Copyright update.
11289 2002-03-08 Akim Demaille <akim@epita.fr>
11291 * doc/autoconf.texi (Invoking autom4te): New.
11293 2002-03-05 Akim Demaille <akim@epita.fr>
11295 * doc/autoconf.texi (Specifying Names): Clarification suggested by
11296 Kevin Ryde.
11298 2002-03-05 Akim Demaille <akim@epita.fr>
11300 Version 2.52i.
11302 2002-03-04 Akim Demaille <akim@epita.fr>
11304 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
11305 * lib/autoconf/general.m4 (AC_INIT): More informative error
11306 message for LIBOBJ.
11308 2002-03-04 Akim Demaille <akim@epita.fr>
11310 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
11311 parallel builds.
11313 2002-03-04 Akim Demaille <akim@epita.fr>
11315 * doc/autoconf.texi (Transforming Names): Equality between target
11316 and host is irrelevant.
11317 (Specifying Names, Canonicalizing): Remove all references to the
11318 backward compatibility hooks. Rather, collect them all into...
11319 (Hosts and Cross-Compilation): this new section.
11320 * doc/install.texi (System Type): Ditto.
11321 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
11322 that `--host' implies cross-compilation.
11324 2002-03-04 Akim Demaille <akim@epita.fr>
11326 * doc/autoconf.texi (Evaluation Macros): New.
11327 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
11328 useless.
11329 (_m4_foreach): Define the variant with immediate evaluation so
11330 that it contains exactly the items, not an expression which
11331 evaluation is the current item.
11332 (m4_re_string, m4_re_word): Don't over quote them.
11334 2002-03-04 Akim Demaille <akim@epita.fr>
11336 Instead of having stacking `shift's evaluated at the end, let
11337 `foreach' loops immediately evaluate them.
11339 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
11340 $*. This is the n-th time I change my mind, but hopefully this is
11341 the last...
11342 (m4_lquote): New.
11343 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
11344 efficient.
11345 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
11346 it was only a hack for m4_text_wrap.
11347 (m4_car2): Remove, replaced by...
11348 (m4_cdr): New.
11349 (_m4_foreach): Adjust.
11350 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
11351 m4_bpatsubst for clarification.
11353 2002-03-04 Akim Demaille <akim@epita.fr>
11355 * doc/autoconf.texi (Changequote is Evil): New.
11357 2002-03-03 Kevin Ryde <user42@zip.com.au>
11359 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
11360 on old systems like SunOS.

11368 of messages.
11370 2002-02-28 Akim Demaille <akim@epita.fr>
11372 * lib/autotest/general.m4 (AT_INIT): Suggest a title to the
11373 message to be sent.

11382 From Akinori Musha.
11384 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
11386 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
11387 translate \r\n to \n.
11389 2002-02-07 Akim Demaille <akim@epita.fr>
11391 Version 2.52h.
11393 2002-02-07 Akim Demaille <akim@epita.fr>
11395 Fix Autoconf PR/209.
11396 Also reported by Frank Denis.
11398 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
11400 2002-02-07 Akim Demaille <akim@epita.fr>
11402 Fix Autoconf PR/207:
11403 AC_PREFIX_PROGRAM fails with dashed program names
11405 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
11406 variable when looking for the prefix program.
11407 Now it also works for shell variables.
11409 2002-02-07 Akim Demaille <akim@epita.fr>
11411 * doc/autoconf.texi (Limitations of Builtins): More about
11412 case/esac.
11414 2002-02-06 Akim Demaille <akim@epita.fr>
11416 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
11417 case/esac, some shells don't support it.
11418 Reported by Zack Weinberg.
11419 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
11421 2002-02-06 Akim Demaille <akim@epita.fr>
11423 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
11424 sure not to introduce newlines in at_groups.
11425 * lib/autotest/Makefile.am (autotest.m4f): Typo.
11427 2002-02-06 Akim Demaille <akim@epita.fr>
11429 * tests/torture.at (Configuring subdirectories): Skip if aclocal
11430 is not available.
11432 2002-02-05 Paul Eggert <eggert@twinsun.com>
11434 * doc/autoconf.texi (Specific Compiler Characteristics):
11435 Describe HP-UX cc bug workaround more accurately.
11436 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
11437 not unsigned long.
11438 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
11439 cross-compilers, too. This undoes some of the most recent change
11440 to this file.
11442 2002-02-05 Akim Demaille <akim@epita.fr>
11444 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
11445 to make sure they are up to date when `check' is run.
11447 2002-02-05 Akim Demaille <akim@epita.fr>
11449 * doc/autoconf.texi (Making testsuite Scripts): Document
11450 package.m4.
11452 2002-02-05 Akim Demaille <akim@epita.fr>
11454 * lib/freeze.mk: New.
11456 2002-02-05 Akim Demaille <akim@epita.fr>
11458 Implement `autom4te --freeze'.
11460 * bin/autom4te.in (&freeze): New.
11461 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
11462 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
11464 2002-02-05 Akim Demaille <akim@epita.fr>
11466 * bin/autom4te.in (&parse_args): Implement `frozen files are
11467 optional are the sum of the previous files on the command line'.
11468 Also, pass `--reload-state=' on them, so...
11469 (handle_m4): don't.
11470 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
11471 (M4sh): Rely on M4sugar.
11472 (Autotest, M4sh, M4sugar): Use frozen files.
11474 2002-01-31 Akim Demaille <akim@epita.fr>
11476 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
11477 * doc/autoconf.texi (Initializing configure): Adjust.
11479 2002-01-30 Akim Demaille <akim@epita.fr>
11481 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
11482 alphanumeric to `-' instead of `_'.
11484 2002-01-30 Akim Demaille <akim@epita.fr>
11486 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
11487 for plain code, the other for cross-compilation code. The latter
11488 is now run with GCC only.
11489 * doc/autoconf.texi (Compilers and Preprocessors): New.
11491 2002-01-30 Akim Demaille <akim@epita.fr>
11493 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
11494 values.
11495 * doc/autoconf.texi (Initializing configure): Explain how to
11496 change AC_INIT default values.
11498 2002-01-29 Akim Demaille <akim@epita.fr>
11500 * tests/torture.at (Configuring subdirectories): Use configure.in,
11501 so that aclocal 1.4 works.
11502 Reported by Alexandre Duret-Lutz and Larry Schmitt.
11504 2002-01-28 Akim Demaille <akim@epita.fr>
11506 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
11507 needs an argument.
11509 2002-01-28 Akim Demaille <akim@epita.fr>
11511 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
11512 AUTOTEST_PATH *after* it was set.
11513 Don't put `.' in the PATH: the user should be precise and `./' if
11514 needed. In addition, given that the test suite does some `cd', if
11515 `.' is in the path, the `tested programs' sections will report
11516 programs found in the test suite's directory, while during the
11517 tests (performed in their own directory), these programs are no
11518 longer visible. In other words, the results is confusing and
11519 useless.
11520 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
11522 2002-01-24 Akim Demaille <akim@epita.fr>

11533 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
11534 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
11535 Bourne. Use /bin/sh.
11536 From Andreas Buening.
11538 2002-01-24 Akim Demaille <akim@epita.fr>

11550 Automake.
11552 2002-01-24 Akim Demaille <akim@epita.fr>
11554 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
11555 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.

11558 2002-01-21 Akim Demaille <akim@epita.fr>
11560 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
11562 2002-01-21 Akim Demaille <akim@epita.fr>
11564 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
11565 message on invalid options.
11566 * bin/autom4te.in (parse_args): Don't use
11567 Autoconf::General::getopt with non valid options.
11569 2002-01-17 Jim Meyering <meyering@lucent.com>
11571 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
11572 $ac_cv_exeext so we don't use an old, invalid, cached value.
11574 2002-01-11 Akim Demaille <akim@epita.fr>
11576 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
11577 Meyering.

11585 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
11586 package.m4, since is really depends upon configure.ac, not
11587 configure.
11588 * doc/autoconf.texi (testsuite Scripts): Adjust.
11589 * tests/Makefile.am (package.m4): New.
11590 EXTRA_DIST it since its a source.
11592 2002-01-06 Akim Demaille <akim@epita.fr>
11594 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
11595 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
11596 and PACKAGE_BUGREPORT from here...
11597 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
11598 arguments.
11599 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
11600 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
11601 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
11602 * tests/tools.at (autoheader): Adjust.
11603 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.

11620 2001-12-17 Jim Meyering <meyering@lucent.com>
11622 * doc/autoconf.texi (New Macros): Tweak wording.
11624 2001-12-14 Akim Demaille <akim@epita.fr>
11626 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
11627 trailing files, don't apply `-rf' to files which might not be
11628 created by configure (core, core.*, and *.core), but just `rm -f'.
11629 Suggested by Jonathan Kamens.
11631 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
11633 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
11635 2001-12-14 Akim Demaille <akim@epita.fr>
11637 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
11639 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
11641 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
11642 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
11643 abs_srcdir, top_srcpath to abs_top_srcdir.
11644 (_AC_OUTPUT_FILES): Adjust.
11645 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
11646 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
11647 * tests/wrappl.in, tests/wrapsh.in: Adjust.
11649 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
11651 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
11652 C/Fortran linking on HP/UX, by extracting the Fortran library
11653 search path from the LPATH line in the $F77 -v output.
11655 2001-12-12 Kevin Ryde <user42@zip.com.au>
11657 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
11658 forbidden file descriptors table.
11660 2001-11-26 Akim Demaille <akim@epita.fr>
11662 * bin/autoscan.in (%c_keywords): Build it at top level.
11663 Map to 1 in order to simplify its uses.
11665 2001-11-26 Akim Demaille <akim@epita.fr>
11667 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
11668 Remove $filepath, useless.
11669 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
11670 variables, they are really part of the tokens.
11671 Split the input line on spaces and then look for tokens.
11672 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
11673 because of `lex$U.$(OBJEXT)'.
11674 (&scan_files): Use "@list" instead of join.
11675 * doc/Makefile.am (CLEANFILES): Add *.fns.
11677 2001-11-26 Akim Demaille <akim@epita.fr>
11679 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
11680 Remove, replaced by...
11681 * tests/wrappl.in: Be common for all the Perl executables.
11682 In particular autoscan and autoheader want -I.
11683 * configure.ac: Adjust.
11684 * lib/autoscan/headers: errno.h is portable.
11686 2001-11-26 Akim Demaille <akim@epita.fr>
11688 * bin/autoscan.in (used): New.
11689 Use it.
11691 2001-11-26 Akim Demaille <akim@epita.fr>
11693 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
11694 directives.
11695 (&scan_sh_file): Remove a duplicate pattern.
11696 (&check_configure_ac): Use long options.
11697 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
11699 2001-11-26 Akim Demaille <akim@epita.fr>
11701 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
11702 Before, having a line containing the opening of a multi line
11703 comment made the whole line be ignored.
11705 2001-11-26 Akim Demaille <akim@epita.fr>
11707 * doc/autoconf.texi (Using an Autotest Test Suite): New.
11708 (testsuite Scripts): Be one of its subsection.
11709 (Autotest Logs): New.
11711 2001-11-26 Akim Demaille <akim@epita.fr>
11713 Test groups are now run two directories deeper.
11715 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
11716 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
11717 at_top_builddir.
11718 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
11719 top_srcdir, builddir and top_builddir.
11720 Use `at_*dir' relatively to the directory containing the
11721 suite, use `*dir' when relatively to the current group dir.
11723 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
11725 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
11726 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
11727 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
11728 spelling errors.
11730 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11732 * doc/autoconf.texi (Using System Type): Add an example of `case
11733 $host' usage so people quit using `case $target' everywhere.
11735 2001-11-22 Akim Demaille <akim@epita.fr>
11737 * doc/autoconf.texi (Installation Directory Variables): Englishoes
11738 spotted by Jim Meyering.
11740 2001-11-16 Paul Eggert <eggert@twinsun.com>
11742 This patch implements a `long double' suggestion by Oliver Kiddle.
11744 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
11745 static, to catch errors if the value isn't known at compile-time
11746 and the compiler supports dynamic arrays. Change its name from
11747 `_array_' to `test_array' to avoid potential name clashes.
11748 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
11749 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
11750 better than double. Catch a bug in GCC 2.95.2 x86.
11751 * doc/autoconf.texi (C Compiler): Document the above.
11752 * NEWS: Likewise.
11754 2001-11-13 Akim Demaille <akim@epita.fr>
11756 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
11757 hand.
11758 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
11760 2001-11-13 Akim Demaille <akim@epita.fr>
11762 * lib/autotest/general.m4 (AT_INIT): After having run the test
11763 group, go back to the initial directory, not to at_suite_dir.
11765 2001-11-13 Akim Demaille <akim@epita.fr>
11767 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
11768 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
11769 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
11770 option.
11771 (AT_CHECK_CONFIGURE): Use absolute paths.
11772 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
11773 The problem is still the old one: there is no means in M4 (that I
11774 know about) to create a defining macro, because there is no means
11775 to create `$1' etc., therefore, the defining macro ``swallows''
11776 all the arguments meant to the defined macro.
11778 2001-11-13 Akim Demaille <akim@epita.fr>
11780 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
11781 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
11782 configure.ac.
11783 * tests/aclocal.m4: Remove, as it is no longer used.
11785 2001-11-13 Akim Demaille <akim@epita.fr>
11787 * lib/autotest/general.m4: Change `tests?' into `groups?' in
11788 variable names when referring to a single test group, or to
11789 `suite' when referring to the whole test suite.
11790 `at_last_test' is removed: m4 compute at_format itself.
11791 (at_stdout, at_stder1, at_stderr): New variables.
11792 (AT_CHECK): Use them.
11794 2001-11-13 Akim Demaille <akim@epita.fr>
11796 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
11797 in PATH.
11798 Create `testsuite.dir/003/run' instead of `testsuite.003'.
11799 Do it as soon as a test fails, don't wait till the end of the test
11800 suite.
11801 Don't remove $as_me.[0-9]*, since these files no longer exist.
11803 2001-11-13 Akim Demaille <akim@epita.fr>
11805 * tests/tools.at: Use absolute paths, since we are no longer run
11806 in place.
11808 2001-11-13 Akim Demaille <akim@epita.fr>
11810 Now that tests are running in their own private dir, there is no
11811 need to list the files to remove at the end of tests groups.
11813 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
11814 (AT_data_files, at_data_files): Remove.
11815 (AT_CLEANUP, AT_DATA): Simplify.
11816 (AT_INIT): Adjust.
11817 Remove the group dir if !debug && !failed.
11818 * tests/atspecific.m4: Adjust.
11820 2001-11-13 Akim Demaille <akim@epita.fr>
11822 Start a new layout for Autotest: `testsuite' creates
11823 `testsuite.dir' in which the at-check-line etc. files are to be
11824 found, and `testsuite.dir/003' where the test group 3 is run.
11826 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
11827 at_check_line_file, at_format, at_test_normalized, at_group_dir
11828 are new variables.
11829 Create the directories.
11830 Use absolute paths for at- files.
11831 (AT_CHECK): Adjust.
11833 2001-11-11 Michael Matz <matz@kde.org>
11835 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
11836 (m4_car2): New.
11837 (m4_car): Properly quote arguments.
11839 2001-11-13 Akim Demaille <akim@epita.fr>
11841 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
11842 with stricter rules on LIBOBJS.
11844 2001-11-12 Paul Eggert <eggert@twinsun.com>
11846 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
11847 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
11848 __PROTOTYPES too.
11850 2001-11-12 Akim Demaille <akim@epita.fr>
11852 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
11854 2001-11-12 Akim Demaille <akim@epita.fr>
11856 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
11857 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
11858 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11859 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
11860 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
11861 specify to what the macro should be defined (typically to 1).
11863 2001-11-12 Akim Demaille <akim@epita.fr>
11865 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
11866 From Jim Meyering.
11868 2001-11-12 Akim Demaille <akim@epita.fr>
11870 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11871 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
11872 definition used by Automake where LEX is +/- "${missing} lex" and
11873 `missing' itself contains variables.
11875 2001-11-12 Akim Demaille <akim@epita.fr>
11877 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
11878 Now that M4sh pushes BODY, the comments were output at the end of
11879 the test suites.
11881 2001-11-08 Akim Demaille <akim@epita.fr>
11883 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
11884 that we can trace macros from aclocal.m4.
11885 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
11886 obsoleted, and redirect to the former anyway.
11887 Reported by Ralf Corsepius.
11889 2001-11-08 Akim Demaille <akim@epita.fr>
11891 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
11892 processed only if present.
11893 * tests/torture.at (Configuring subdirectories): Use autoreconf
11894 instead of successive calls to autoconf.
11895 Add a nonexistent subdirectory to exercise the patch above.
11896 Reported by Ralf Corsepius.
11898 2001-11-08 Kevin Ryde <user42@zip.com.au>
11900 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
11901 doesn't accept .S files.
11903 2001-11-07 Akim Demaille <akim@epita.fr>
11905 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
11906 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
11907 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
11908 * bin/autom4te.in (warn_forbidden): New.
11909 (handle_output): Use it.
11910 Read m4_pattern_forbid with messages.
11912 2001-11-05 Akim Demaille <akim@epita.fr>
11914 * bin/autom4te.in (--normalize): Remove.
11915 * lib/autom4te.in: Adjust.
11917 2001-11-05 Akim Demaille <akim@epita.fr>
11919 * tests/Makefile.am (testsuite): Rename this target as...
11920 ($(TESTSUITE)): this.
11921 From Nicolas Joly.
11923 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
11925 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
11926 the --prefix option, also remove it's argument.
11928 2001-11-05 Akim Demaille <akim@epita.fr>
11930 * doc/autoconf.texi (testsuite Invocation): Update.
11931 (Writing testsuite.at): Update.
11933 2001-11-03 Akim Demaille <akim@epita.fr>
11935 * doc/autoconf.texi: s/@code/@command/ where appropriate.
11937 2001-11-03 Akim Demaille <akim@epita.fr>
11939 * lib/Autom4te/General.pm: (&catfile, &canonfile)
11940 (&file_name_is_absolute): New, wrappers around routines from
11941 File::Spec.
11942 Use and export them.
11943 (&find_configure_ac): Optionally take a directory where to look at.
11944 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
11945 the arguments.
11946 Default @ARGV to `.', not find_configure_ac.
11947 (&autoreconf): Argument is a directory.
11948 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
11949 * doc/autoconf.texi (autoreconf Invocation): Update.
11951 2001-11-03 Akim Demaille <akim@epita.fr>
11953 * lib/Autom4te/General.pm (@export_vars, @export_subs)
11954 (@export_forward_subs): New.
11955 Add basename, dirname, and fileparse.
11956 (@EXPORT): Adjust.
11957 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
11958 Don't look for aclocal flags if we already know aclocal is not
11959 used.
11960 Move aclocal.m4t only if it exists.
11961 Reported by Ezra Peisach.
11963 2001-11-03 Akim Demaille <akim@epita.fr>
11965 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
11966 passed on command line, defaulting to ./configure.ac if present.
11967 (&maybe_autoreconf, File::Find): Remove, unused.
11968 (&autoreconf): If autoconf is not used, don't try to trace.
11970 2001-11-02 Akim Demaille <akim@epita.fr>
11972 * configure.ac: Bump to 2.52g.
11974 2001-11-02 Akim Demaille <akim@epita.fr>
11976 Version 2.52f.
11978 2001-11-02 Akim Demaille <akim@epita.fr>
11980 * config/config.guess, config/config.sub, doc/standards.texi:
11981 * config/lispdir.m4: Update from masters.
11982 * configure.ac: Bump to 2.52f.
11984 2001-11-02 Akim Demaille <akim@epita.fr>
11986 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
11987 Don't run aclocal when aclocal.m4 is not from aclocal.
11988 From Ezra Peisach.
11989 Don't run libtoolize and gettextize if --install is not given.
11991 2001-11-01 Paul Eggert <eggert@twinsun.com>
11993 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
11994 be invoked before _AS_LINENO_PREPARE.
11995 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
11996 than character ranges.
11998 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
11999 invoking AS_BASENAME. Set the locale variables to 'C' if
12000 possible, as POSIX requires this to get the traditional
12001 behavior.
12002 * doc/autoconf.texi (Special Shell Variables): Describe the above.
12004 2001-10-31 Paul Eggert <eggert@twinsun.com>
12006 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
12007 with {}, as that triggers a bug in Bash 2.05.
12009 (_AS_LINENO_PREPARE): Use Sed rather than
12010 Awk. Fix the sed prepass to work even if there are multiple
12011 instances of $LINENO on the same line. Do not substitute for
12012 other variables like $LINENOT. Do not check file dates; such a
12013 check is unreliable on sufficiently fast machines, and removing
12014 the check makes the code simpler and more reliable. Check for
12015 output and chmod failures.
12017 * doc/autoconf.texi (Special Shell Variables): Document
12018 the above.
12020 2001-10-31 Akim Demaille <akim@epita.fr>
12022 * tests/Makefile.am (atconfig): Remove this target, Automake
12023 handles it now.
12025 2001-10-31 Akim Demaille <akim@epita.fr>
12027 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
12028 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
12029 provided, while it is optional.
12030 * configure.ac: Adjust.
12032 2001-10-26 Paul Eggert <eggert@twinsun.com>
12034 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
12035 lib/Autom4te/Struct.pm:
12036 Require Perl 5.005_03 instead of just 5.005, as some tests fail

12042 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.

12063 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
12064 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
12065 POSIX decided to standardize on the int flavor of strerror_r.
12066 Always do char* test, as there's no reason not to.
12067 Assign to a char* var, to catch strerror_r that returns int*.
12069 * doc/autoconf.texi (Particular Functions):

12136 (AS_BASENAME_SED): Do not assume GNU sed semantics.
12137 (AS_BASENAME): Use 'basename' if that works; then try 'expr';

12141 contains white space.
12142 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

12292 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

12377 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

12518 * tests/Makefile.am (package.m4): Remove.
12520 2001-09-22 Akim Demaille <akim@epita.fr>
12522 Rely on `$LINENO' when possible instead of `__oline__'.
12524 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
12525 `$LINENO' support replacement when not supported.
12526 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
12527 them explicitly to be sure they are not output before this section
12528 (via m4_require). Cosmetic only.
12529 * lib/autoconf/c.m4, lib/autoconf/general.m4,
12530 * lib/autoconf/programs.m4: Replace all the occurrences of
12531 `__oline__' with `$LINENO'.
12532 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
12534 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
12536 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
12537 character (u: -> ue) in a code comment.
12538 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
12539 it works.
12541 2001-09-21 Akim Demaille <akim@epita.fr>
12543 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
12544 Suggested by Jim Meyering.
12546 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12548 * lib/autoconf/programs.m4: Use extensions listed in
12549 $ac_executable_extensions when looking for programs.

12553 * lib/autoconf/general.m4: Fix a small Englisho.

12555 setting up ac_dir_suffix and ac_top_builddir.
12556 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
12558 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

12561 PATH_SEPARATOR.
12562 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
12563 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
12564 be used instead of ':'.
12565 * lib/autotest/general.m4: Replace occurrences of ':' in
12566 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
12568 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12570 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
12571 arguments. Fixed a typo.
12573 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12575 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
12576 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
12578 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12580 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

12587 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12589 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
12590 already have $file). Set output files to binary mode (helps avoid
12591 CR issues on DOSish systems).
12593 2001-09-19 Akim Demaille <akim@epita.fr>
12595 * lib/autotest/general.m4: Englishoes.
12596 From Tim Van Holder and Alexey Mahotkin.
12598 2001-09-18 Paul Eggert <eggert@twinsun.com>
12600 * doc/autoconf.texi (Common Shell Constructs): New node,
12601 documenting AS_DIRNAME.
12602 (Limitations of Usual Tools): Refer to it when discussing dirname.
12603 Also, update discussion of POSIX standard to reflect latest draft.
12605 * lib/autoconf/c.m4:
12606 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
12608 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
12609 Do not pass a first argument with leading '-'
12610 to expr, by parenthesizing initial integers that might be negative.
12612 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
12613 now merely checks whether it is an error to pass an argument
12614 to getpgrp.
12616 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
12617 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
12618 whether it is a (compile-time) error to pass an argument to
12619 getpgrp. This simpler test supports the revised documentation,
12620 and is all that AC_FUNC_GETPGRP's users really need.
12622 2001-09-18 Akim Demaille <akim@epita.fr>
12624 * doc/autoconf.texi (Limitations of Make) <$<>: New.
12626 2001-09-18 Akim Demaille <akim@epita.fr>

12634 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
12635 correctly.
12636 Add test for AS_BASENAME.
12637 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
12638 added test. It now correctly handles /1/2/3/, returning '3' not ''.
12639 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
12640 * tests/base.at: Fixed the expected responses. The old ones were
12641 one line out...
12642 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
12643 the documentation claims it should (and how it behaved in 2.13).
12645 2001-09-18 Akim Demaille <akim@epita.fr>
12647 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
12648 the AC_CONFIG_COMMANDS invocation.
12649 This also solves the name clash problems.
12650 Don't set the package's ID.
12651 * lib/m4sugar/Makefile.am (version.m4): Revamp.
12652 No longer to be shipped.
12653 (version.in): Remove.
12654 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
12655 * lib/autoconf/status.m4: Adjust.
12656 Use `m4_PACKAGE_STRING'.
12657 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
12658 the only optional argument is the name of the test suite.
12659 Expect `package.m4' to define the package signature.
12660 * lib/autom4te.in (Autotest): Add `package.m4?'.
12661 * tests/Makefile.am (package.m4): New.
12662 * tests/suite.at: ifnames is a victim.
12664 2001-09-18 Akim Demaille <akim@epita.fr>
12666 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
12667 AC_LIBSOURCE, AC_CONFIG_FILES.
12668 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
12669 program version string doesn't match the package's.
12670 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
12671 after `(cached)'.
12673 2001-09-17 Paul Eggert <eggert@twinsun.com>
12675 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12676 Allow expression to return any value that can fit into unsigned long
12677 (not int, as before). Check for output errors.
12679 2001-09-17 Bruno Haible <haible@ilog.fr>
12681 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12682 Always include <stdio.h> and <stdlib.h>. Evaluate
12683 the expression in an extra function before these includes. Call
12684 fprintf "%d" only after ensuring the argument is of type 'int'.
12685 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
12687 2001-09-17 Paul Eggert <eggert@twinsun.com>
12689 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
12690 or CFLAGS=-O5. In that case, the linker has a relaxed view of
12691 fatal errors, and AC_CHECK_LIB causes it to include libraries even
12692 when they don't exist.
12694 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
12695 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
12696 need it.
12698 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
12699 version with the version used by fileutils 4.1, except use
12700 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
12701 we don't need it.
12703 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
12705 2001-09-13 Akim Demaille <akim@epita.fr>
12707 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
12708 _first_.
12709 Reported by Gerrit P. Haase.

12713 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

12737 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
12739 2001-09-13 Akim Demaille <akim@epita.fr>
12741 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
12743 2001-09-13 Akim Demaille <akim@epita.fr>
12745 * lib/autotest/general.m4 (AT_INIT): Create and remove
12746 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
12747 test suites can cohabit.
12749 2001-09-13 Akim Demaille <akim@epita.fr>
12751 * tests/mktests.sh: Don't output banners for empty test files.
12753 2001-09-13 Akim Demaille <akim@epita.fr>
12755 Test suites can be run independently of configure.

12801 2001-09-10 Akim Demaille <akim@epita.fr>
12803 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

12836 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
12837 in addition, it introduces useless differences in logs.
12838 (AT_INIT): Let atconfig and atlocal be both optional.
12839 Adjust PATH computation.

12850 to avoid GCC warnings.
12851 From Uwe Seimet.
12853 2001-09-05 Akim Demaille <akim@epita.fr>
12855 * bin/autom4te.in: --language is -l, not -s.
12857 2001-09-05 Akim Demaille <akim@epita.fr>
12859 Be ready to handle filenames as stupid as `dnl.at', for if even
12860 the maintainer is dumb enough to do that...
12862 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
12863 excellence in M4 quotation: consider `__file__' is active.

12896 New, extracted from main.
12897 Use IO::File wherever possible.

12900 Don't invoke `_au_disable', since ac was not loaded, but just

12930 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
12931 (testsuite Scripts): There is no such thing as `atconfig.in'.

12934 2001-08-31 Akim Demaille <akim@epita.fr>
12936 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
12937 inverse order.
12939 2001-08-31 Akim Demaille <akim@epita.fr>
12941 * bin/autoupdate.in (@include): `installcheck' revealed the path
12942 to m4sugar was lacking!
12944 2001-08-31 Akim Demaille <akim@epita.fr>
12946 * man/Makefile.am (.x.1): We really have to pass
12947 autom4te_perllibdir.
12949 2001-08-31 Akim Demaille <akim@epita.fr>
12951 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
12952 debug scripts, in particular passing explicitly listed tests to
12953 run is stupid.
12955 2001-08-31 Akim Demaille <akim@epita.fr>
12957 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
12958 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
12959 Use directly autom4te, not autoconf.
12960 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
12962 2001-08-31 Akim Demaille <akim@epita.fr>
12964 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
12965 * bin/autoheader.in (%symbol): Strip arguments of macros.
12967 2001-08-31 Akim Demaille <akim@epita.fr>
12969 * doc/autoconf.texi: Catch up -I, --include changes.
12971 2001-08-31 Akim Demaille <akim@epita.fr>
12973 * bin/autom4te.in (&parse_args): Die on unknown languages.
12974 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
12975 need for autoconf.
12976 Promote --include over --macrodir and other obsolete options.
12978 2001-08-31 Akim Demaille <akim@epita.fr>
12980 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
12981 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
12982 * bin/autom4te.in ($autoconf): Pass --force.
12983 `print $out' doesn't print `$_' but `$out'.
12984 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
12985 (autoheader): Pass --force since the test suite goes too fast for
12986 the time stamps.
12987 Adjust to the new autoheader messages.
12989 2001-08-31 Akim Demaille <akim@epita.fr>
12991 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
12992 Check the completeness of the #template.
12993 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
12994 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
12995 invocation.
12997 2001-08-31 Akim Demaille <akim@epita.fr>
12999 * lib/Autom4te/General.pm (&find_file, &update_file): New.
13000 * bin/autoupdate.in, bin/autoheader.in: Adjust.
13001 Drop AC_MACRODIR dead for real.
13002 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
13003 `autoheader: `config.hin' is created'.
13004 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
13006 2001-08-31 Akim Demaille <akim@epita.fr>
13008 * bin/autoheader.in: Rewrite in Perl.
13009 * tests/autoheader: Adjust.
13011 2001-08-31 Akim Demaille <akim@epita.fr>
13013 * bin/autoconf.in (--include, -I): New option.
13014 Map --localdir, --autoconf-dir onto it.
13015 Forward autom4te's options instead of interpreting them.
13016 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
13017 There is no such envvar since the inception of autom4te.cfg.
13018 * bin/autom4te.in (&parse_args): Uniquify `@include'.
13019 * bin/autoupdate.in: Adjust, and perform more control.
13020 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
13021 * tests/autoconf: Dittowise.
13023 2001-08-31 Akim Demaille <akim@epita.fr>
13025 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
13026 * bin/autom4te.in (&find_file): Support `FILE?' standing for
13027 optionally `FILE'.
13028 Use -e, not -f, since /dev/null for instance is OK.
13029 (&parse_args): Adjust.
13030 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
13032 2001-08-31 Akim Demaille <akim@epita.fr>
13034 * configure.ac: Also find tested executables in bin.
13035 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
13036 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
13037 installed peer executables, only PATH is allowed to resolve it.
13038 Pass `autoconf_dir' via options, not via invisible envvars.
13039 * lib/Autom4te/General.pm (&find_peer): Remove.
13040 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
13041 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
13042 * man/Makefile.am: Let help2man rely on PATH instead of trying to
13043 find the executables for it.
13044 * tests/Makefile.am: Major cleanup. Too lazy to document...
13045 * tests/atlocal.in: Remove all the obscure envvar manipulations.
13046 We only need PERL.
13047 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
13048 indeed related to running the test suite, while passing
13049 --autoconf-dir and others is related to running non installed
13050 Autoconf executables. So don't do that, leave it to...
13051 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
13052 * tests/autoscan: New.
13053 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
13054 refer to library files: rely on --language.
13056 2001-08-29 Akim Demaille <akim@epita.fr>
13058 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
13059 s/--set/--language/.
13061 2001-08-29 Akim Demaille <akim@epita.fr>
13063 * doc/autoconf.texi: Strip the @nodes.
13064 Suggested by Paul Eggert.
13065 (Initializing configure): Typo.
13067 2001-08-29 Akim Demaille <akim@epita.fr>
13069 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
13070 Suggested by Paul Eggert.
13072 2001-08-29 Akim Demaille <akim@epita.fr>
13074 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
13075 download in a tmp dir.
13077 2001-08-29 Akim Demaille <akim@epita.fr>
13079 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
13080 case insensitive OSes out there :(
13081 From Tim Van Holder.
13083 2001-08-29 Akim Demaille <akim@epita.fr>
13085 * lib/autom4te.in: New.
13086 * lib/Makefile.am (edit, autom4te.cfg): New.
13087 * bin/autom4te.in (BEGIN): Simplify.
13088 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
13089 (&load_configuration): New. Use it.
13090 (&parse_args): Support --mode, --set, and --melt.
13091 * bin/autoconf.in: Simplify and adjust.
13092 * tests/Makefile.am (AUTOMAKE): Use --set.
13093 * tests/atlocal.in: Adjust.
13094 * BUGS: distcheck and check are weak.
13096 2001-08-29 Akim Demaille <akim@epita.fr>
13098 * lib/autotest/general.m4: Use
13099 foo=`(command) 2>/dev/null`
13100 not
13101 foo=`command` 2>/dev/null
13102 (at-devnull): Rename as...
13103 (AT-devnull): this.
13104 (--clean): Remove AT-* files too.
13105 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
13106 Reported by Nicolas Joly.
13108 2001-08-28 Akim Demaille <akim@epita.fr>
13110 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
13111 quotes inside single quotes.
13112 Reported by Nicolas Joly.
13114 2001-08-28 Kevin Ryde <user42@zip.com.au>
13116 * doc/autoconf.texi (Function Portability): Mention C right shifts.
13118 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
13120 * lib/autotest/general.m4: Reword some messages.
13121 (AT_INIT): Check for the `times' builtin before using it.
13122 Support test ranges as arguments to the testsuite.
13123 Have -e imply -d as the help text suggested.
13125 2001-08-27 Akim Demaille <akim@epita.fr>
13127 * Makefile.maint: Formatting changes.
13128 (do-po-update, po-update, cvs-update, update): New targets.

13140 * lib/autotest/general.m4 (AT_INIT): Log the command line.
13141 Support `VAR=VAL' as arguments.
13142 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
13143 may be set via the command line.
13145 2001-08-27 Akim Demaille <akim@epita.fr>
13147 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
13148 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
13149 first the build dirs, then the src dirs.

13152 2001-08-27 Akim Demaille <akim@epita.fr>
13154 * lib/autotest/general.m4 (AT_INIT): Output the definition of
13155 at_data_files earlier.
13156 (--clean, -c): New option.
13157 * tests/Makefile.am: Use this option.
13159 2001-08-27 Akim Demaille <akim@epita.fr>
13161 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
13162 `ac_top_builddir' to mimic Automake's vocabulary, which much more
13163 readable.
13164 Adjust callers.
13165 * doc/autoconf.texi (Configuration Actions): Document the vars
13166 available in commands.
13167 Emphasize the risks of collisions in init-cmds.

13171 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
13172 (Initializing configure): this new node.
13174 2001-08-27 Akim Demaille <akim@epita.fr>

13187 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move
13188 to...
13189 * lib/autoconf/autoheader.m4: this new file.
13190 * lib/autoconf/general.m4 (AH_OUTPUT, AH_VERBATIM)
13191 (_AH_VERBATIM_OLD, AH_TEMPLATE, _AH_TEMPLATE_OLD, AH_TOP, AH_BOTTOM):
13192 Move to...

13195 2001-08-27 Akim Demaille <akim@epita.fr>
13197 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
13198 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
13199 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
13200 -> ac_dir).
13201 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
13202 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
13204 2001-08-27 Akim Demaille <akim@epita.fr>
13206 * lib/autoconf/autoconf.m4 (AC_CONFIG_COMMANDS)

13229 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
13230 (AMTAR): Help automake define it.
13231 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
13232 needed, 1.5 can have a macro and a target with the same name.
13233 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
13234 * m4/strip.m4: New.

13247 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
13248 Adjust callers.
13249 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
13250 the name of the directory they're in, instead of the filename,
13251 since version.m4 is now in m4sugar, but m4_acversion must not be
13252 classified as an Autoconf macro.
13253 ($input_m4): Don't qualify the path to m4sugar.
13254 Rather, pass autoconf_dir to m4.
13255 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
13256 * tests/suite.at: Require 2.52c.
13258 2001-08-27 Akim Demaille <akim@epita.fr>

13270 of config.log on traps.
13271 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
13272 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
13273 for config.status'.
13274 Open the log as soon as possible.
13275 Use the same log introduction as configure's.
13277 2001-08-22 Paul Eggert <eggert@twinsun.com>
13279 * doc/autoconf.texi (Indices): New node.
13280 Move indices out of the top level menu and into this submenu.
13282 2001-08-22 Akim Demaille <akim@epita.fr>
13284 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13285 AC_TRY_COMMAND.
13286 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
13288 2001-08-22 Akim Demaille <akim@epita.fr>
13290 * lib/autoconf/general.m4 (AC_SHELL_PATH_WALK, AC_CHECK_PROG)

13327 * configure.ac (AT_CONFIG): Fix the path.
13328 * m4/atconfig.m4 (AT_CONFIG): Don't use EOF but ATEOF so that 2.52
13329 can be used.
13331 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
13333 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
13334 program with AC_LANG_PROGRAM before feeding it to
13335 AC_COMPILE_IFELSE. Cleanup grep usage.
13337 2001-08-20 Akim Demaille <akim@epita.fr>
13339 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
13340 * NEWS, README, README-alpha, TODO, tests/README: This package is
13341 `Autoconf', not `autoconf' (the executable).
13343 2001-08-20 Akim Demaille <akim@epita.fr>
13345 Info readers seem to need `Index' in the index node title :(
13347 * doc/autoconf.texi: Reverse the 2001-08-15 change which
13348 simplified index node names.
13350 2001-08-20 Akim Demaille <akim@epita.fr>
13352 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
13353 arguments are not literals.
13354 * doc/autoconf.texi (Input) <AC_INIT>: Arguments must be literals.
13355 Specify the output variables, and macros defined.
13357 2001-08-20 Akim Demaille <akim@epita.fr>
13359 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
13360 (Examining Syntax) <AC_TRY_COMPILE>
13361 (Examining Libraries) <AC_TRY_LINK>
13362 (Test Programs) <AC_TRY_RUN>: These macros double quote some of
13363 their arguments.
13364 Reported by Werner Lemberg.
13366 2001-08-20 Akim Demaille <akim@epita.fr>
13368 * lib/autotest/general.m4 (AT_INIT): Compute top_builddir,
13369 top_srcdir and srcdir from at_topbuild_2_topsrc and at_testdir.

13394 Huh!?!?! There are still some user EOF tags used, which prevents
13395 their use in AC_CONFIG_COMMANDS for instance...
13397 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
13398 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

13461 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

13477 2001-08-17 Akim Demaille <akim@epita.fr>
13479 * doc/autoconf.texi: Work around Texinfo buglets.
13480 (Transformation Rules): One example is enough, users are expected
13481 to have their brains on. And BTW, use DESTDIR.
13482 (dvar): New macro. Use it.
13484 2001-08-17 Akim Demaille <akim@epita.fr>
13486 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

13526 value.

13534 (cvs-dist): depends upon it.
13536 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
13538 * tests/Makefile.am: Use a clean-local rule to remove
13539 autom4te.cache (it's a directory, not a file.
13540 * Makefile.am: Ditto (but maintainer-clean-local).
13542 2001-08-15 Akim Demaille <akim@epita.fr>
13544 * bin/autom4te.in (@m4_warning): New.
13545 (&handle_m4): Use it.
13546 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
13547 warnings are issued at each run.
13548 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
13549 is in the src tree.
13551 2001-08-15 Akim Demaille <akim@epita.fr>
13553 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
13554 don't waste time running `autoupdate --version' works.
13555 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
13557 2001-08-13 Akim Demaille <akim@epita.fr>
13559 * doc/autoconf.texi (ma): Rename this index as...

13612 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
13614 * tests/semantics.at (AC_C_BIGENDIAN): New test.
13616 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13618 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
13619 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
13620 * doc/autoconf.texi (C Compiler Characteristics): Update
13621 documentation for AC_C_BIGENDIAN.
13623 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13625 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
13626 magic values from an object file when cross-compiling.
13627 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
13629 2001-08-10 Akim Demaille <akim@epita.fr>
13631 * bin/autom4te.in (&handle_output): Don't use `grep' with side
13632 effects.
13633 Suggested by Russ Allbery.
13635 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
13637 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
13638 current $prefix to the sub-configures.
13640 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
13642 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
13643 extension (needed on BeOS). Reported by Guido van Rossum.
13645 2001-08-09 Akim Demaille <akim@epita.fr>
13647 * bin/autom4te.in ($icache): Load it only if older than autom4te.
13649 2001-08-07 Akim Demaille <akim@epita.fr>
13651 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
13652 removed.
13653 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
13654 No need to remove the files before and after the each test, before
13655 each test and at the end of the suite is enough.
13656 Display only the children `times', not the shell's.
13657 If the test failed or was skipped, at-times is not available.
13659 2001-08-07 Akim Demaille <akim@epita.fr>
13661 Always produce testsuite.log, including when there are no
13662 failures. This helps getting information on skipped tests, and
13663 duration of the tests. Err, implement the latter btw.
13665 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
13666 Dump information on the first run of each test.
13667 (AT_CLEANUP): Create `at-times' containing the duration of the
13668 test group.
13670 2001-08-07 Akim Demaille <akim@epita.fr>
13672 The use of `dumpstat' revealed that `len' was used although it
13673 should not. m4_text_wrap was using it, but in the Autoconf world
13674 where it is legal. Hence (i) test M4sh in its own world, not
13675 Autoconf's, and (ii), ahem, fix the bug :)
13677 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
13678 does not like `' instead of [].
13679 (AT_INIT): Forbid `^_?AT_'.
13680 And don't output such tokens.
13681 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
13682 `script.as', and `autom4te.cache'.
13683 Remove `empty' and `macro' which are no longer used.
13684 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
13685 * tests/m4sugar.at: Use it.
13686 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
13688 2001-08-07 Akim Demaille <akim@epita.fr>
13690 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
13692 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
13694 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
13696 2001-08-04 Akim Demaille <akim@epita.fr>
13698 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
13699 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
13700 AC_TRY_LINK.
13701 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
13702 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
13703 (AC_F77_MAIN): Likewise.
13705 2001-08-04 Akim Demaille <akim@epita.fr>
13707 Don't rely on M4sugar outputting the patterns in files, since we
13708 might process the output _without_ running m4, hence without these
13709 files.
13711 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
13712 * bin/autom4te.in (@Request::includes): Remove, unused.
13713 (@Request::source): Rename as...
13714 (@Request::input): this.
13715 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
13716 (&handle_output): Fetch the patterns from the traces.
13717 `$forbidden' and `$allowed' are constant: use m//o.
13718 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
13719 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
13721 2001-08-04 Akim Demaille <akim@epita.fr>
13723 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
13724 autoconf', i.e., in addition to caching traces, cache the output.
13726 * bin/autom4te.in (Request::cache): Rename as...
13727 (Request::id): this.
13728 ($cache, $icache, $tcache, $ocache): New.
13729 (&handle_m4): Save M4 output in the cache instead of $tmp.
13730 (&handle_output): Adjust.
13731 (&up_to_date_p): Check that the output cache is up to date too.
13732 (top level): Run `&handle_m4' iff force or the cache is invalid.
13733 Run `&handle_output' if the output cache is more recent.
13735 2001-08-04 Akim Demaille <akim@epita.fr>
13737 * bin/autom4te.in ($force): New.
13738 (&parse_args, &print_usage): -f, --force is a new option.
13739 (&handle_output): CPP directives might have spaces after `#'.
13740 (&parse_args): The first file only can be frozen.
13742 2001-08-04 Akim Demaille <akim@epita.fr>
13744 Don't let autom4te compute the `include' traces several times:
13745 first check that the trace cache file is up to date, and then
13746 compare its timestamp with that of the output.
13748 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
13749 the preamble. Don't require 5.005 as Autom4te::General does it,
13750 and better yet (use `use', not `require'!).
13751 * lib/Autom4te/Struct.pm: Rename the last occurrences of
13752 Class::Struct as Autom4te::Struct.
13753 * lib/Autom4te/General.pm (File::stat): Use it.
13754 (&mtime): New, export it.
13755 * bin/autom4te.in: Use it.
13756 Declare `$req' is invalid if it is outdated.
13757 Don't declare it valid before saving it if something went wrong.
13759 2001-08-04 Akim Demaille <akim@epita.fr>
13761 Autom4te shall not encode Autoconf data, and preselecting traces
13762 must be proposed to the users.
13764 * bin/autom4te.in (@required_trace): Remove.
13765 (@preselect): New.
13766 (&parse_args, &print_usage): -p, --preselect is a new option.
13767 (&up_to_date_p): Adjust.
13768 * bin/autoconf.in: Preselect some Autoconf macros.
13770 2001-08-04 Akim Demaille <akim@epita.fr>
13772 * tests/tools.at (autoconf --trace: user macros): Check traces on
13773 macros invoked without arguments, and macros invoked with multiple
13774 lines arguments.
13776 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
13778 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
13779 arguments.
13781 2001-08-03 Akim Demaille <akim@epita.fr>
13783 * bin/autoconf.in ($@): Work around the usual sh bug.
13784 From Nicolas Joly.
13786 2001-08-03 Akim Demaille <akim@epita.fr>
13788 Clean up the handling of the M4 builtins tracing exception.
13790 * bin/autom4te.in (Request::request): Don't complete M4 builtins
13791 trace requests.

13793 (@m4_builtin): this.
13794 (%m4_builtin_alternate_name): New.
13795 (&parse_args): Complete the trace requests with alternate names.
13796 (&handle_traces): Hence no longer do it here.
13797 (&trace_requests): Remove, unused.
13799 2001-08-03 Akim Demaille <akim@epita.fr>
13801 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
13802 m4_if, and m4_wrap.
13804 2001-08-03 Akim Demaille <akim@epita.fr>
13806 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
13807 (m4_divert_pop): Dump the whole diversion stack when a diversion
13808 mismatch happens.
13809 * bin/autom4te.in (&handle_output): Remember of the first
13810 occurrence of a possibly undefined macro, not the last.
13811 Complain about the possibly undefined macros in the same order as
13812 the appear in the output.
13813 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
13814 * tests/tools.at (autoconf: forbidden tokens, basic)
13815 (autoconf: forbidden tokens, exceptions): No longer sort
13816 autoconf's stderr, as it is now deterministic.
13817 Check that `dnl' is caught.
13819 2001-08-01 Akim Demaille <akim@epita.fr>
13821 * configure.ac: Bump to 2.52c.
13823 2001-08-01 Akim Demaille <akim@epita.fr>
13825 Version 2.52b.

13833 2001-08-01 Akim Demaille <akim@epita.fr>
13835 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and

14233 compiler, not the preprocessor.
14234 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use

14240 2001-07-03 Akim Demaille <akim@epita.fr>

14269 * aclang.m4 (AC_F77_DUMMY_MAIN): New macro to detect whether a
14270 dummy alternate main is required even if the user provides her own
14271 'main'.

14273 provide an alternate 'main' function name, using the 'main' from
14274 the Fortran libraries.
14275 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
14276 cross-language link tests can be performed successfully.
14277 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
14278 after $LIBS, for consistency; this should be the general rule since

14282 2001-06-29 Pavel Roskin <proski@gnu.org>
14284 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
14285 at-stdout and at-stderr instead of removing the newline
14286 from the echo output, which is not guaranteed to work.
14288 2001-06-28 Jens Petersen <petersen@redhat.com>
14290 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to
