1 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3 Shell functions and variables may share a namespace.
4 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
5 limitation.
7 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
9 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
10 gnulib.
12 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
14 * lib/autoconf/status.m4: Fix a couple of comment typos.
16 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
18 2007-11-13 Jim Meyering <meyering@redhat.com>
20 Clean up the rule to create "expr".
21 * tests/Makefile.am (expr): Don't redirect directly to target.
22 Redirect just once, not for each echo statement.
23 Use $@, not literal "expr".
25 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
27 Don't worry about preprocessor when testing long long.
28 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
29 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
30 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
31 These no longer check for preprocessor flaws.
32 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
33 Do not check for preprocessor flaws.
35 2007-11-13 Jim Meyering <meyering@redhat.com>
37 Adapt dependencies, now that a version change doesn't modify configure.ac
38 * GNUmakefile: Remove "make clean" kludge.
39 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
40 configure.ac.
41 Don't redirect directly to target.
42 Use $@, not literal "version.m4".
44 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
46 * doc/autoconf.texi (Making testsuite Scripts): Document
47 ":;{" shorthand as in previous patch.
49 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
51 * doc/autoconf.texi (Limitations of Builtins): Document problem
52 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
53 for the workaround.
54 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
55 Use ":;{" shorthand.
56 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
58 2007-11-12 Jim Meyering <meyering@redhat.com>
60 Add more non-srcdir build support.
61 * GNUmakefile (dummy): Split a long line.
62 Add -v option to autoreconf invocation.
64 Remove the autoreconf-provided INSTALL, so that we regenerate it.
65 * GNUmakefile (dummy): Remove INSTALL.
67 Remove racy commands to build scripts in bin/ and tests/.
68 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
69 are guaranteed to be built, remove the rules that tried to build
70 them. Before, with a parallel build, these rules could lead to
71 two processes writing tests/wrapper.in concurrently.
73 Build in man/ only *after* building in bin/ and tests/.
74 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
75 in both bin/ and tests/.
77 Accommodate non-srcdir build-from-checkout.
78 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
79 Use git's --git-dir=$srcdir/.git option.
80 Add quotes, in case tarball_version_file contains shell meta-characters.
81 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
82 * configure.ac: Pass "." to git-version-gen.
84 Avoid spurious test failures due to version skew.
85 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
87 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
89 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
90 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
91 Remove conftest.dSYM directory.
92 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
93 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
94 Remove `conftest.*' recursively.
95 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
96 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
97 Likewise.
98 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
99 * THANKS: Update.
100 Report and analysis by Jeff Squyres and Peter O'Gorman.
102 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
104 Fix typos in variable names.
105 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
107 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
109 Document that $((expression)) is not portable.
110 * doc/autoconf.texi (Shell Substitutions): Here.
112 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
114 Ignore configure --help* errors due to LINENO-impaired shells.
115 * tests/torture.at (Configuring subdirectories, Deep Package):
116 In the --help* tests in read-only trees, make `.' temporarily
117 writable again for the `stderr' file, and ignore errors due to
118 the attempt to write configure.lineno.
119 Report by Patrick Welche.
121 2007-11-10 Jim Meyering <meyering@redhat.com>
123 Generate package.m4 in build-dir, not srcdir.
124 * tests/Makefile.am (package.m4): Adjust target.
125 Don't redirect directly to $@.
126 (CLEANFILES): Add package.m4.
127 ($(TESTSUITE)): Depend on just-built package.m4, not the one
128 in $(srcdir).
129 When running $(AUTOTEST), search "." before searching $(srcdir).
131 Avoid a race condition that would make parallel "distclean" fail.
132 * tests/Makefile.am (distclean-generic): Replace the default,
133 automake-provided rule with an identical one, but with an additional
134 dependency on distclean-local. Simply adding the dependency would
135 cause automake not to emit the rule at all.
136 * BUGS: Building with -jN works, now.
138 Distribute git-version-gen.
139 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
140 since GNUmakefile is distributed, and requires it for dist* rules.
142 Remove two more generated files from version control.
143 * INSTALL: Remove generated file.
144 * lib/autoscan/autoscan.list: Remove generated file.
146 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
148 * GNUmakefile (PATH): Remove stray apostrophes; they become
149 part of PATH, which isn't wanted here.
151 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
153 New config files output variable `top_build_prefix'.
154 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
155 `top_build_prefix'.
156 * doc/autoconf.texi (Preset Output Variables): Document it.
157 * NEWS: Update.
158 Report by Bob Friesenhahn.
160 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
161 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
162 function, to parametrize arithmetic with expr vs. the shell.
163 Use it where possible.
164 Suggestion by Benoit Sigoure.
166 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
168 Adjust the documentation of autotest WRT atlocal.
169 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
170 when using Automake, to write a rule to produce atlocal, since it's
171 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
172 distributed, not atconfig.in.
174 2007-11-04 Eric Blake <ebb9@byu.net>
176 Update list information.
177 * README: Mention new autoconf-commit list.
178 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
180 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
182 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
184 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
186 * build-aux/.gitignore: Ignore mkinstalldirs.
188 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
190 2007-11-03 Jim Meyering <meyering@redhat.com>
192 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
193 * build-aux/git-version-gen: This syncs from coreutils.
195 Adjust the build procedure so "make check" works reliably.
196 * README-hacking: Include an extra step between "make" and
197 "make check" to ensure that the latter passes.
199 Use just-built tools, when possible.
200 * GNUmakefile (PATH): Set and export here, ...
201 (dummy): ... rather than here.
203 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
204 and Andreas Schwab <schwab@suse.de>
206 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
207 exit status bug.
209 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
211 * configure.ac (AC_PREREQ): Require version 2.60, for
212 AC_PROG_SED, AC_PROG_GREP.
214 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
215 and Jim Meyering <meyering@redhat.com>
216 and Andreas Schwab <schwab@suse.de>
217 and Eric Blake <ebb9@byu.net>
219 Document a bug in GNU Bash with compound commands and redirections.
220 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
221 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
222 workaround.
224 2007-11-03 Eric Blake <ebb9@byu.net>
226 Support m4 1.4.5 in testsuite.
227 * tests/torture.at (Define a newline): Exclude line numbers in
228 error message.
229 Reported by Ralf Wildenhues.
231 2007-11-03 Jim Meyering <meyering@redhat.com>
233 Remove automake-provided files from version control.
234 * build-aux/elisp-comp: Remove file.
235 * build-aux/install-sh: Remove file.
236 * build-aux/missing: Remove file.
237 * build-aux/mdate-sh: Remove file.
238 * build-aux/.gitignore: New file.
239 Suggestion from Ralf Wildenhues.
241 2007-11-03 Eric Blake <ebb9@byu.net>
243 Adjust version comparison to account for git snapshot numbers.
244 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
245 component separator.

250 2007-10-30 Bruno Haible <bruno@clisp.org>
252 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
253 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
254 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
255 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
256 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
257 Suggested by Paul Eggert.
259 2007-10-28 Jim Meyering <meyering@redhat.com>
261 * README-hacking: Autoconf, Automake, and Perl are required to build.
262 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
264 2007-10-28 Jim Meyering <meyering@redhat.com>
266 README-hacking: Recommend running autoreconf -vi.
267 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
268 so that we use just-built tools when they're available.
269 Suggestions from Ralf Wildenhues.
271 2007-10-28 Jim Meyering <meyering@redhat.com>
273 Make inter-release --version output more useful.
275 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
276 which indicates that it is built using the 19th change set
277 (in _some_ repository) following the "v2.61a" tag, and that 58dd
278 is a prefix of the commit SHA1.
279 * build-aux/git-version-gen: New file.
280 * configure.ac: Run it to set the version.
281 (AM_INIT_AUTOMAKE): Don't check NEWS here.
282 * Makefile.am (dist-hook): Arrange so that .version appears only
283 in distribution tarballs, never in a checked-out repository.
284 * .gitignore: Add .version here, too. Just in case.
285 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
286 not configure.ac, now that the version number changes automatically.
288 Ensure that $(VERSION) is up to date for dist-related targets.
289 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
290 git-version-gen doesn't match $(VERSION), but only for dist targets.
292 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
294 Fix `Deep Package' failure with a configure script early in PATH
295 * tests/torture.at (Deep Package): Add `.' early in PATH.
296 Report by Jim Meyering.

320 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
321 and Eric Blake <ebb9@byu.net>
323 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
324 problem reported by Bruno Haible in
325 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
327 2007-10-22 Eric Blake <ebb9@byu.net>
329 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
330 preprocessor.
332 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
334 Don't check for bug in HP-UX 11.00 cpp.
335 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
336 Use -1ull rather than -1u, since that causes problems with gnulib; see
337 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
339 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

345 test names.
347 2007-10-21 Eric Blake <ebb9@byu.net>

355 escaping of backslash in here-documents.
357 Fix `Deep Package' test failure on FreeBSD.
358 * tests/torture.at (Deep Package): Do not add `.' to $PATH
359 unnecessarily. Do not try running `/bin/sh configure' with a
360 configure script to be found in $PATH, if the shell does not do
361 this resolution. Fixes test failure on FreeBSD.
363 Fix config header generation with AIX awk.
364 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
365 script, use helper array D_is_set, as `" 0"' does not evaluate
366 to true for AIX awk.
368 2007-10-21 Eric Blake <ebb9@byu.net>
370 * tests/autotest.at (Banners): Reinstate test, with typo

403 * lib/autotest/general.m4 (BANNERS): New named diversion.
404 (TESTS_END): Diversion no longer used.
405 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
406 shell function, which prints only as needed, using an associative
407 array of banner text from a special diversion.
408 <PARSE_ARGS_END>: No longer need awk to find banners.
409 <TESTS>: Banners are no longer processed by main driver loop, so
410 we no longer need case statement.
411 (AT_BANNER): Rewrite to populate new diversion.
412 (AT_SETUP): Each test invokes its own banner. No output is needed
413 to the TESTS diversion.
414 * doc/autoconf.texi (Writing Testsuites): Document slight
415 semantics change.
416 * tests/autotest.at (AT_BANNERS): Enhance test.

439 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Fix
440 duplication bug by using new macro.
441 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
442 programs with stdin redirected, so programs that don't
443 understand --version won't try to behave interactively.
444 * tests/autotest.at (Tested programs): Catch this bug.
445 * tests/m4sugar.at (m4@&t@_append): Test new macro.
446 * tests/local.at (AT_TESTED): Add m4, perl.
447 * doc/autoconf.texi (Text processing Macros): Document
448 m4_append_uniq_w, and update text on m4_append.
449 * NEWS: Document the addition.
451 2007-10-17 Eric Blake <ebb9@byu.net>
453 Function cleanup.
454 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): Convert

464 Reject FreeBSD m4.
465 * m4/m4.m4 (AC_PROG_GNU_M4): Also check for frozen file support.

471 (m4@&t_max and m4@&t_min): New tests.
472 * doc/autoconf.texi (Evaluation Macros) <m4_apply>: Enhance
473 description.
475 2007-10-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
477 * TODO: multiline args in config files and headers work now.
479 Autotest: do not use shell functions for individual tests.
480 * lib/autotest/general.m4 (AT_INIT) <at_func_test>: Merely
481 extract the source test source, do not invoke it.
482 (AT_SETUP, AT_CLEANUP): Source test code outside shell function.
483 * tests/autotest.at (Fallacy): Actually let the inner suite fail,
484 expect exit status of 1.

504 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Avoid errors when `.'
505 is not writable, use 'cp -p' in this case, in the hope that it
506 will not actually be needed. Still try removing files, in case
507 of other write errors.
508 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): For ac_confdir,
509 use $as_myself, not $0.
510 (_AC_INIT_HELP): For --help=recursive, if the subdir does not
511 exist, try again in the the source tree. This change assumes
512 that the subpackage configure script is capable of running

1472 Based in part on Steven G. Johnson's investigations for the AX_OPENMP
1473 macro in the Autoconf macro archive.
1475 2007-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1477 * bin/autom4te.in: Fix typos.
1479 2007-05-16 Noah Misch <noah@cs.caltech.edu>

1506 renamed to "autoconf-invocation"
1508 * doc/autoconf.texi (Caching Results): The CACHE-ID variable
1509 in the examples should not use the internal "ac_" prefix.
1511 2007-05-05 Noah Misch <noah@cs.caltech.edu>
1513 * lib/autotest/general.m4 (_AT_NORMALIZE_TEST_GROUP_NUMBER): Use `eval'.

1523 * lib/autoconf/lang.m4, lib/autoconf/c.m4,
1524 lib/autoconf/fortran.m4, lib/autoconf/erlang.m4: Cleanup of
1525 section titles and other comments; no code change.
1527 2007-05-01 Kevin Ryde <user42@zip.com.au>
1529 * doc/autoconf.texi (Particular Programs): Typo
1530 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
1532 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
1534 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
1535 'configure' will fail if the shell lacks proper support for shell
1536 functions. Suggested by RMS.
1538 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
1540 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
1541 about Solaris /bin/printf '%010000x' 123. Problem reported by
1542 Bruno Haible.
1544 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
1546 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
1547 for a.* when searching for executables, as this prevents users
1548 from having files like a.c. Problem reported by Ralf Wildenhues in:
1549 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
1550 This fixes a problem introduced on 2000-12-19.

1560 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
1561 AC_CHECK_TYPE, AC_CHECK_TYPES.
1562 * doc/autoconf.texi (Generic types): C types must be type-names
1563 (the C terminology), not type-ids (the C++ term). C++ types
1564 must not be anonymous.
1565 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
1566 for C++; this drops support for anonymous struct and union types,
1567 which were problematic anyway.
1568 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
1569 for C++.
1571 2007-04-12 Jim Meyering <jim@meyering.net>

1583 * doc/autoconf.texi (Generic Types): Document the restrictions
1584 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
1585 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
1586 with objects too. Document the restrictions on its use.
1587 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
1588 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
1589 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
1590 works but the latter doesn't, then it's a valid type.
1591 This lets people use function types and so forth.
1592 For C++ there doesn't seem to be a simple solution, so leave it alone.
1593 (AC_CHECK_SIZEOF): Allow argument to be a variable.
1594 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
1595 AC_CHECK_TYPE; that wasn't documented or necessary.
1597 2007-04-11 Stepan Kasal <kasal@ucw.cz>
1599 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

1612 2007-04-06 Paul Eggert <eggert@cs.ucla.edu>
1614 * doc/autoconf.texi (Particular Types): AC_C_LONG_DOUBLE is now
1615 obsolescent. Suggested by Bruno Haible.
1616 * NEWS: Document this.
1618 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
1620 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
1621 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
1622 default still has the problem. Problem reported by Bruce Korb.
1624 2007-03-28 Stepan Kasal <kasal@ucw.cz>
1625 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1642 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
1643 checks for unsigned long long int.
1645 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
1647 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
1648 nonstandard grep R.E. escape sequences.
1650 2007-03-17 Jim Meyering <jim@meyering.net>
1652 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
1653 (Limitations of Usual Tools): Also list \< and \>, and mention that
1654 HP-UX's grep, like the one from Solaris, does not support that syntax.
1656 2007-03-09 Stepan Kasal <kasal@ucw.cz>
1658 * doc/autoconf.texi (Specifying Names): `--host' does not
1659 change the build type.
1661 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
1663 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
1664 suggests AC_CONFIG_HEADERS.

1671 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Fix typo "__LITLE_ENDIAN__".
1672 Problem reported by Paolo Bonzini in:
1673 http://lists.gnu.org/archive/html/autoconf-patches/2007-02/msg00024.html
1674 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
1675 universal binaries. Problem reported by Elias Pipping.
1677 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
1679 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
1680 * doc/autoconf.texi (C Compiler): Document this. There is a new
1681 extra argument ACTION-IF-UNIVERSAL.
1682 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
1683 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
1684 Reindent for sanity's sake.
1686 2007-02-24 Eric Blake <ebb9@byu.net>
1688 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
1689 copyright.

1691 * lib/autotest/general.m4 (AT_INIT): Likewise.
1692 (_AT_DECIDE_TRACEABLE): Fix syntax highlighting.
1694 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1696 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
1697 status of rm so we know when it failed.
1698 If cleaning of test dir failed before running the test, warn.
1699 Output the line separator in verbose mode before the warning
1700 to make clear the warning belongs to the following test.
1702 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
1704 * doc/autoconf.texi (Parentheses): Mention problem with (( in
1705 shells.

1717 carriage return.
1718 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
1719 with traditional Awk and begin.
1720 * tests/torture.at (Limitations of Builtins): Document the problem
1721 with Bash 2.03 printf.

1725 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
1727 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
1728 input from /dev/null in awk test, so even Solaris /usr/bin/awk
1729 will not wait for input with a script containing only a BEGIN
1730 rule.
1732 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
1734 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version

1754 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
1756 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
1757 latest version.
1758 (Shell Substitutions): Note problems with @{var:=value} etc.
1759 Add a new section for problems with @{#var} etc. Problem noted
1760 by Ralf Wildenhues. See:
1761 http://lists.gnu.org/archive/html/libtool-patches/2005-01/msg00157.html
1763 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1765 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
1766 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
1767 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
1768 substitution will still be done by the special code.
1769 Report by Jim Meyering.
1771 * doc/autoconf.texi (File System Conventions): Mention that
1772 $PATH_SEPARATOR is for the build system only.
1773 Report by Keith Marshall.

1784 Report against Automake by Patrick Welche.
1786 2007-01-15 Stepan Kasal <kasal@ucw.cz>
1788 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
1790 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1792 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
1793 early on the reader side, drop stderr of the input to avoid
1794 `broken pipe' error output; this may happen even with shell
1795 builtin `echo' of some bash versions. Reports by Ian Macdonald
1796 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
1798 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1800 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

1811 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
1812 * doc/autoconf.texi (Signed Overflow Examples): Give more
1813 discussion about the allow_superuser_privileges example,
1814 and change it a bit to make things clearer.
1815 (Optimization and Wraparound): Clarify whether the compiler
1816 will generate an infinite loop for the example derived from
1817 Autoconf's mktime test.
1818 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
1819 Also, clarify unsigned multiplication overflow.
1821 2007-01-04 Eric Blake <ebb9@byu.net>
1823 * bin/Makefile.am (RELEASE_YEAR): New macro.
1824 (edit): Use it to supply correct copyright year to scripts.
1825 * bin/autoconf.as (version): Use it.
1826 * bin/autoheader.in ($version): Likewise.
1827 * bin/autom4te.in ($version): Likewise.
1828 * bin/autoreconf.in ($version): Likewise.
1829 * bin/autoscan.in ($version): Likewise.
1830 * bin/autoupdate.in ($version): Likewise.
1831 * bin/ifnames.in ($version): Likewise.
1833 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
1835 * doc/autoconf.texi (Integer Overflow): Revised based on today's
1836 feedback. The most important changes document what happens when
1837 you convert an out-of-range value to a signed integer type, and
1838 say that (sum < a) != (b < 0) reliably detects overflow when sum =
1839 a + b.
1841 * doc/autoconf.texi (Integer Overflow): Greatly expand and
1842 rewrite, taking notions from the recent discussion on the gcc and
1843 autoconf mailing lists; please see
1844 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
1845 and follow the many links.
1846 (Integer Overflow Basics, Signed Overflow Examples):
1847 (Optimization and Wraparound, Signed Overflow Advice):
1848 (Signed Integer Division): New sections.
1850 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
1852 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
1853 preprocessor macro arguments in traced name.
1854 * doc/autoconf.texi (Defining symbols): Document longstanding
1855 support for AC_DEFINE-ing macros with arguments, and document
1856 behavior when the same variable has multiple AC_DEFINEs.
1857 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
1858 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
1859 macros directly, giving much shorter and simpler code.
1861 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
1863 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
1864 space before "$ac_configure_args" to prevent a 'config.status
1865 --recheck' failure if ac_configure_args doesn't contain a leading
1866 space. This works around a problem with the XEmacs configure.ac,
1867 which uses the (undocumented) ac_configure_args variable
1868 inconsistently with Autoconf.
1870 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
1872 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
1873 Include <limits.h>, and use its INT_MAX to rewrite the
1874 j loop so that it does not overflow 'int'. Problem reported by
1875 Ralf Wildenhues in
1876 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
1877 Play it safe by shifting left by 1 rather than multiplying by 2,
1878 as GCC is less likely to optimize this away when the value
1879 is signed (when it assumes overflow leads to undefined behavior).
1880 Also, don't assume time_t uses two's complement.
1882 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1884 * tests/torture.at (Substitute a 2000-byte string): Avoid using
1885 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
1886 dumps core on it. Report by Tim Rice.
1888 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1890 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
1891 --disable-option-checking to --help output even when
1892 AC_PRESERVE_HELP_ORDER is not used.
1893 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
1894 --with argument, rather than argument with [-.] replaced by
1895 underscores.

1897 wrong section.
1899 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
1901 * NEWS: Warnings are now generated by default for unknown
1902 --enable-* and --with-* options.
1903 * doc/autoconf.texi (Option Checking): Renamed from
1904 (Configure Option Checking). Tighten up the wording a bit.
1905 (External Software, Package Options): Cross-reference to Option
1906 Checking, and use this to shorten our section.
1907 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
1908 "$x" to test "x$foo" != x.
1909 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
1910 Don't warn if $enable_option_checking is "no".
1911 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
1912 ac_unrecognized_opts to the empty string.
1913 Don't echo the unrecognized opts, as this might mishandle
1914 backslashes or leading -.
1915 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
1916 usage next to the other --disable-FEATURE options in the
1917 help string.
1919 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1921 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
1922 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
1923 Print warning for unrecognized --with and --enable options
1924 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
1925 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
1926 Disable option checking when subdirs are configured.
1927 (AC_OUTPUT): If warnings are enabled, print warning about
1928 unrecognized --with and --enable options at the end of
1929 the configure output (as well as at the beginning).
1930 * doc/autoconf.texi (Option Checking): New node.
1931 Document new option warning functionality.
1933 2006-12-16 Eric Blake <ebb9@byu.net>
1935 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
1936 * NEWS: Start news for current version.
1938 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
1940 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1941 Define HAVE_GETMNTENT to 1, not to the empty string.
1942 Problem originally reported by Jochen Friedrich in
1943 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
1945 This change prompted by a problem report by Andrey Simonenko in
1946 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
1947 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
1948 object-like macros only, in the traditional portable character
1949 set.
1950 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
1951 Warn about attempts to define things that are not identifiers.
1952 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
1953 awful hack that AC_DEFINEd macro names containing parentheses.
1955 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
1957 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
1958 too drastic, even if Texinfo in theory requires it for info mode.
1960 (config.status Invocation): Renamed back from Recreating a
1961 Configuration).
1962 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
1963 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
1965 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1967 * NEWS: Version 2.61a.
1969 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1970 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1972 * NEWS: Document changes with echo and printf, and the lack
1973 of limits on the total size of multi-line values of substituted
1974 variables, and the AC_FUNC_FSEEKO fix.
1976 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
1978 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
1979 Writing configure.ac.
1980 (Autoconf Input Layout): Renamed from configure.ac Layout.
1981 (Recreating a Configuration): Renamed from config.status Invocation.
1982 (Obsolete Recreation): Renamed from Obsolete config.status Use.
1983 (acconfig Header): Renamed from acconfig.h.
1984 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
1985 (Writing Testsuites): Renamed from Writing testsuite.at.
1986 (Autom4te Cache): Renamed from autom4te.cache.
1988 * BUGS: Remove mention of VPATH problem, since it's now documented
1989 not to be a bug in the Autoconf build procedure itself, but rather
1990 a problem with the proprietary `make' programs.
1992 * doc/autoconf.texi (Build Directories): Add a cross reference
1993 to VPATH and Make.
1995 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
1996 * doc/standards.texi: Sync from gnulib.
1998 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
1999 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
2000 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
2001 generated automatically.
2003 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
2005 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
2006 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
2007 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
2009 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2011 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
2012 `CEOF$ac_eof' special marker, the awk script cannot contain a
2013 line matching `^CEOF', so this is not needed any more.
2014 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
2015 special marker in the test.
2017 2006-12-06 Stepan Kasal <kasal@ucw.cz>
2019 * tests/tools.at (autom4te preselections): Use `find -newer';
2020 remove one of the sleeps.
2022 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
2023 more readable, using ...
2024 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
2026 * doc/autoconf.texi (autoheader Invocation): Do not double-
2027 quote the parameter of `AH_BOTTOM' in the example.
2029 2006-12-05 Stepan Kasal <kasal@ucw.cz>
2031 * doc/autoconf.texi (Configuration Headers): Remove the
2032 example with multiple input files.
2033 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
2034 multiple input files.
2036 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2038 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
2039 creating the awk substitution script, handle one input line at a
2040 time, so that the maximum length of a substituted (multi-line)
2041 value is not limited by the size of the sed pattern space.
2042 The trade-off is a slightly repetitive sed script.
2043 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
2044 can only have up to 7 characters, due to Solaris 10 /bin/sed.
2045 * tests/torture.at (Substitute a 2000-byte string): Increase the
2046 test with several long lines, they should not be caught by sed
2047 limits any more.
2049 * tests/tools.at (autom4te preselections): New test, to flag
2050 entries missing from autom4te.cfg.
2051 Report by David Byron <dbyron@hheld.com>.
2053 * tests/torture.at (Substitute a 2000-byte string): Actually use
2054 AC_PROG_AWK, so the last change works as intended.
2055 (Substitute and define special characters): Likewise.
2056 (Substitute a newline): Likewise.
2058 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
2059 instead of `awk' consistently.
2060 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
2061 * tests/torture.at (Torturing config.status): Test both the
2062 result of AC_PROG_AWK and plain awk.
2063 (Substitute a 2000-byte string): Likewise.
2064 (Substitute and define special characters): Likewise.
2065 (Substitute a newline): Likewise.
2067 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
2069 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
2070 can be assigned to a function pointer. Problem reported by
2071 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
2072 part of a patch by Ralf Wildenhues in that same bug report.
2074 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
2076 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
2077 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
2079 2006-12-01 Eric Blake <ebb9@byu.net>
2081 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
2082 cross-compiling from cygwin to mingw.
2083 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
2084 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
2085 to lib/autoconf/c.m4.
2087 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2089 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
2090 string for more reliable failure. Wrap the entire test that
2091 causes the broken Solaris printf to dump core, in a subshell,
2092 so the segmentation fault message is reliably suppressed.
2093 Fix shell expansion errors by using /usr/ucb/echo always;
2094 avoid an error on systems without it by another subshell.
2095 Avoid m4 expansion of `$1'. Set the zeroth argument of the
2096 subshell-$as_echo to `as_echo', for better error message.
2098 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2100 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
2101 `BASH_SOURCE' contain a newline, set them to empty, as they may
2102 not be unset.
2104 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
2106 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
2107 years and is too hard to maintain now. The last straw was
2108 reported by Jerker Baeck in
2109 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
2110 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
2111 * doc/autoconf.texi (Particular Functions): Move
2112 AC_FUNC_SETVBUF_REVERSED from here...
2113 (Obsolete Macros): ... to here. Say that it does nothing now.
2114 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
2115 Turn into (almost) a no-op.
2117 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
2118 (AC_C_VOLATILE):
2119 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
2120 These macros are obsolescent and new applications shouldn't need them.
2121 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
2122 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
2123 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
2124 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2125 (AC_FUNC_VPRINTF): Likewise.
2126 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
2127 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
2128 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
2130 * doc/autoconf.texi (Setting Output Variables): Mention that
2131 @VAR1@VAR2 has unspecified behavior. Problem reported by
2132 Ralf Wildenhues.
2133 * NEWS: Mention this.
2135 * Makefile.am: Put only a single '#' into the copyright notice,
2136 so that it's also present in the output file. Standardize wording
2137 in makefile copyright notices to match GNU coding standards.
2138 * bin/Makefile.am: Likewise.
2139 * doc/Makefile.am: Likewise.
2140 * lib/Makefile.am: Likewise.
2141 * lib/freeze.mk: Likewise.
2142 * lib/autoconf/Makefile.am: Likewise.
2143 * lib/autoscan/Makefile.am: Likewise.
2144 * lib/autotest/Makefile.am: Likewise.
2145 * lib/m4sugar/Makefile.am: Likewise.
2146 * man/Makefile.am: Likewise.
2147 * tests/Makefile.am: Likewise.
2148 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
2149 one-line file.
2151 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2153 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
2154 in the sed script that mangles the awk script: delete up to the
2155 first exclamation mark only.
2156 * tests/torture.at (Substitute and define special characters):
2157 Test '!' too.
2159 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2161 Rewrite config files generation: avoid quadratic growth in
2162 the number of substituted variables by using awk instead of sed
2163 for the bulk of the substitutions.
2164 * NEWS: Mention this.
2165 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
2166 forbidden in the output (and thus input) file.
2167 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
2168 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
2169 generate just one large awk script for substitutions,
2170 eliminating much of the earlier complexity, while adding some
2171 new complexity. Only expand the substitution templates at
2172 configure time, for smaller configure script size. If
2173 _AC_SUBST_FILES are used, test 'awk' for working getline support
2174 at config.status time. If absent, interpolate through the
2175 shell. The awk script was written with much help
2176 from Paolo Bonzini and Paul Eggert.
2177 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
2178 (_AC_SED_FRAG_NUM): Likewise.
2179 (_AC_SUBST_CMDS): Renamed from...
2180 (_AC_SED_CMDS): ...this.
2181 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
2182 * tests/torture.at (Substitute a 2000-byte string): Also
2183 substitute a line with 1000 words, and a variable with several
2184 long lines.
2185 (Substitute and define special characters): Test awk special
2186 characters, and put substitution input strings `@foo@' in the
2187 output, to test that no recursion happens; test several other
2188 combinations from Paolo Bonzini.
2190 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
2192 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
2193 that replaced echo with AS_ECHO where this wasn't necessary.
2194 Problem reportd by Ralf Wildenhues.
2195 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
2196 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
2197 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
2199 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2201 * lib/freeze.mk (GREP): Removed, no need to initialize this.
2203 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
2205 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
2206 that traditional Awk lacks 3-arg "split". It has it.
2207 Mention that FS must be a single character, and a few other
2208 99-byte limits of traditional Awk.
2209 Mention that if (i in a) doesn't work with traditional Awk.
2211 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
2213 * tests/autotest.at (BSx641-newline in command):
2214 (BS-BS-newline in command, BSx640-newline in command):
2215 (Newline-CODE-BS-newline in command):
2216 (Single-quote-BS-newline in command):
2217 (Single-quote-newline-BS-newline in command):
2218 Use printf '%s\n' instead of echo, for portability to hosts
2219 where echo interprets backslashes. This will break on hosts
2220 that lack printf, but for now let's assume all such hosts
2221 are dead (if not, we should get reports of test failures).
2223 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2225 'echo' has some portability problems, when given a first argument
2226 with a leading '-', or when given any argument containing '\'.
2227 Avoid using 'echo' in these cases.
2228 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
2229 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
2230 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2231 * lib/autotest/general.m4 (AT_INIT): Likewise.
2232 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
2233 argument might be unportable.
2234 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
2235 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
2236 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
2237 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
2238 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
2239 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
2240 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
2241 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
2242 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
2243 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
2244 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):

2246 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
2247 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
2248 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
2249 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
2250 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
2251 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
2252 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
2253 * bin/autoconf.as: Redo verbose flag implementation, as the old
2254 scheme wouldn't work with AS_ECHO.
2255 * lib/autotest/general.m4 (AT_INIT): Likewise.
2256 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
2257 Don't use ECHO_T, since ECHO_N is now reliable.
2258 * lib/autotest/general.m4 (AT_INIT): Likewise.
2259 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
2260 rather than using a here-document to put the script into a file.
2261 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
2262 use AS_ECHO.
2263 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
2264 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
2265 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
2266 bug, but we might as well stop using ECHO_N and ECHO_C internally.
2267 * lib/autotest/general.m4 (AT_SETUP): Likewise.
2268 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
2269 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2270 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
2271 operand, as AS_ECHO requires. Avoid double file name expansion.
2272 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
2273 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
2274 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
2275 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
2276 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
2277 Double-quote strings that would otherwise contain M4 comments.
2278 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
2280 * configure.ac (AC_INIT): Bump to 2.61a.
2281 * NEWS: Likewise.
2283 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2285 Version 2.61.
2287 * configure.ac (AC_INIT): Bump to 2.61.
2288 * NEWS: Likewise.
2290 * tests/autotest.at (Macro with backslash in a test title):
2291 Comment out for now, as this tests neither fails nor passes
2292 reliably. Problem reported by Ralf Wildenhues.
2294 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
2296 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
2297 in previous change, which caused test failures.
2299 2006-11-16 Stepan Kasal <kasal@ucw.cz>
2301 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
2302 code for --enable, --disable, --with, and --without to...
2303 (_AC_INIT_PARSE_ENABLE): ... a new macro.
2304 * doc/autoconf.texi (Package Options):
2305 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
2307 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
2309 Import these changes from config via gnulib:
2311 2006-11-15 Ben Elliston <bje@gnu.org>
2313 From Josselin Mouette <joss@debian.org>:

2344 Import these changes from texinfo via gnulib:
2346 2006-11-08 Karl Berry <karl@gnu.org>
2348 * build-aux/texinfo.tex (\dopdfimage): look for png, jpg/jpeg/JPG, and
2349 as well as pdf images, since they are supported in pdftex with
2350 no further ado.
2352 2006-11-05 Karl Berry <karl@gnu.org>
2354 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.

2366 first argument may also contain dots.
2368 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
2370 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
2371 benefit of platforms like Solaris+GCC where it is common to have a
2372 non-working g++ installation.
2374 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2375 and Joel E. Denny <jdenny@ces.clemson.edu>
2376 and Paul Eggert <eggert@cs.ucla.edu>
2378 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs

2384 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set

2386 Imported from a similar patch to gnulib by Bruno Haible.
2388 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2390 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

2410 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
2411 properly.
2412 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
2413 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
2414 argument. Extend to check titles printed by ./micro-suite and
2415 ./micro-suite -l and the title in micro-suite.log.
2416 (Backquote in a test title,
2417 Single-quote in a test title,
2418 Double-quote in a test title): Don't expect failure anymore.
2419 (Backslash in a test title): Put a non-whitespace character after the
2420 backslash so that Bourne shells might actually see it as an escape
2421 sequence.
2422 (Brackets in a test title,
2423 Pound in a test title,
2424 Comma in a test title,
2425 Quoted Macro in a test title,

2432 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
2433 The visible effect was a stray [] in the testsuite output.
2435 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2437 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
2438 `trap ... 0' inside a function, for AIX sh.
2440 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
2442 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
2443 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
2444 5363) simply issues a warning when dividing by zero at compile
2445 time. Problem reported by Elias Pipping.
2447 2006-10-26 Eric Blake <ebb9@byu.net>
2449 * THANKS: Update.
2450 * doc/autoconf.texi (Evaluation Macros): Improve the example to
2451 show effect on macros that expand with commas.
2452 Reported by Joel E. Denny.
2454 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):

2479 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
2480 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
2481 reported by Nelson H. F. Beebe for Coreutils 6.4.
2483 * tests/tools.at (autoconf --trace: user macros): Remove test
2484 for tracing multiline macros, since m4 1.4.7a uses a different
2485 way to number lines. Problem reported by Ralf Wildenhues.
2487 2006-10-24 Stepan Kasal <kasal@ucw.cz>
2489 * bin/autom4te.in (handle_m4): Do not redirect stdin to
2490 /dev/null since the heuristics for interactive behaviour was
2491 fixed in CVS m4.
2493 * bin/autom4te.in: With --force, always refresh the output
2494 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

2515 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
2516 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
2518 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2520 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.

2547 looking for special shell characters.
2548 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
2549 macro defined by AS_VAR_PUSHDEF before passing it as a
2550 parameter.

2561 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
2563 (Imported from Automake.)
2564 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
2565 which incorrectly sets the mode of an existing destination
2566 directory. In some cases the unpatched install-sh could do the
2567 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
2568 system. We hope this is rare in practice, but it's clearly worth
2569 fixing. Problem reported by Alex Unleashed in
2570 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
2571 Also, don't bother to check for -m bugs unless we're using -m;
2572 suggested by Stepan Kasal.
2574 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>

2580 is enabled by default with gnu and gnits strictness.
2581 Report from Bruno Haible.
2583 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
2584 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
2585 gnu and gnits modes.
2587 Import this change from Config:
2589 2006-09-20 Ben Elliston <bje@gnu.org>

2592 Import this change from Gnulib:
2594 2006-09-16 Karl Berry <karl@gnu.org>
2595 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
2596 to avoid sectioning errors.

2605 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
2606 (\code): must use new \...Char values, since now ` is active.
2608 2006-08-26 Karl Berry <karl@gnu.org>
2609 * build-aux/texinfo.tex (\textdegree): New command.
2611 2006-08-12 Karl Berry <karl@gnu.org>

2616 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
2618 2006-10-13 Stepan Kasal <kasal@ucw.cz>
2620 * doc/autoconf.texi (Autoheader Macros): Warn that the text
2621 added to the template can get mangled.
2623 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2625 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
2626 include the default headers, and redefine obstack_chunk_alloc
2627 and obstack_chunk_free. Fixes false failure with glibc.
2629 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
2631 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
2632 for backward compatibility with Libtool 1.5.22. Problem reported
2633 by Ralf Wildenhues.
2635 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2637 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
2638 AC_PROG_CC.

2641 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>

2648 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
2649 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
2650 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
2651 Use a better substitute, by inspecting the output of "ls"
2652 rather than just using ":".
2653 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
2654 rather than AS_EXECUTABLE_P, since we needn't worry about
2655 non-regular files here.
2657 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
2658 due to configuration hassles with this. See Tonya Underwood's report
2659 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
2660 * doc/autoconf.texi (Special Shell Variables): Likewise.

2670 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
2671 initialization which is not inherited through the environment
2672 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
2673 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
2675 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
2677 * doc/autoconf.texi (Limitations of Usual Tools): Describe
2678 problems with mkdir -p -m.
2680 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
2682 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
2683 comment about ac_cpp_err; it was incorrect, and anyway
2684 ac_cpp_err is being removed below.
2685 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
2686 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
2687 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
2688 nobody uses it.
2689 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
2690 with werror_flag and conftest.err and so forth. This is more
2691 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
2692 and anyway the user shouldn't normally want to see this gorp logged.
2693 Problem reported by Ralf Wildenhues.
2694 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
2695 empty, not 'no', since the rest of the code uses 'test -z'.
2697 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
2699 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2700 Use a single call to AC_DO_TOKENS rather than multiple, for
2701 efficiency.
2702 (_AC_LINK_IFELSE): Test that resulting file is executable.
2703 Problem reported by mwoehlke in
2704 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
2706 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
2707 than creating a file to use with test -x; this is much faster.
2709 2006-10-02 Bruno Haible <bruno@clisp.org>
2711 * lib/autom4te.in (Automake-preselections): Add
2712 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
2714 2006-09-27 Stepan Kasal <kasal@ucw.cz>
2716 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
2717 standard error, `experr' should be used, not `expout'.
2719 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2721 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
2722 fseeko testing program twice; just use the earlier result.
2723 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2724 Set cache var to 'unknown' (not 'no') if leaving the macro unset
2725 still doesn't let the program compile.
2726 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
2727 failed.
2729 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
2730 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
2731 include it, without including anything else.
2732 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
2733 expressions.
2734 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
2736 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2738 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
2739 `error.h', and include it, for a `error_at_line' prototype.
2740 Use a nonempty format string in the link test.
2741 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
2742 for a declaration of wait3.

2747 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
2748 can apply to constants too, and that it checks for macro defns.
2749 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

2751 values. Problem reported by Ralf Wildenhues.

2840 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
2841 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
2842 for the existence of the directory at configure-time. That's
2843 too late, anyway. Problem reported by Stefan Seefeld.
2845 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
2846 7.1.4 /usr/bin/posix/sh described by Tim Rice in
2847 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
2849 2006-09-11 Stepan Kasal <kasal@ucw.cz>
2851 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
2852 works with GNU M4 1.4.3 again; make the normalized form
2853 match the current m4 message; fix the description.
2854 * test/tools.at (autom4te cache): Adapt to the change.
2856 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
2858 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
2859 to catch glibc bug 2821
2860 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
2862 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
2863 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
2864 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
2865 assume C89.
2867 2006-09-08 Stepan Kasal <kasal@ucw.cz>
2869 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

2877 AM_ENABLE_MULTILIB.
2879 2006-09-05 Paul Eggert <eggert@cs.ucla.edu>
2881 * doc/autoconf.texi (Preset Output Variables): srcdir and
2882 top_srcdir are not necessarily relative. Problem reported
2883 by Dries Kimpe.
2885 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2887 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
2888 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
2889 accept files with extension `.f'. For consistency, also prefer
2890 xlf over f77.
2891 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
2892 from last patch.
2894 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>
2896 * lib/autoconf/erlang.m4 (AC_ERLANG_CHECK_LIB): Added substitution

2907 before AC_PROG_FC, due to a bug in Autoconf.
2909 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
2911 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
2912 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
2913 except the first two arguments are reversed.
2914 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
2915 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
2916 caches nor outputs a diagnostic. Suggested by Bruno Haible.
2917 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
2918 equivalent to the old AC_COMPUTE_INT.
2919 (AC_COMPUTE_INT): No longer caches or reports. New signature.

2921 * tests/base.at (AC_CACHE_CHECK_INT): New test.
2922 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
2924 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
2926 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
2927 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
2928 programs should use their Gnulib counterparts.
2929 * doc/autoconf.texi (Particular Functions): Likewise.
2930 (Macro Names, testsuite Invocation): Replace uses of these
2931 obsolete macros with uses of non-obsolete macros.

2940 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Fix logic that was
2941 mistakenly swapped on 2006-08-15.
2943 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
2945 * NEWS: Version 2.60a.
2947 2006-08-25 Stepan Kasal <kasal@ucw.cz>
2949 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Remove the IPA/IPO
2950 file created by the PGI compiler.

2955 simplify the code.
2957 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
2959 Fix Lex library problem reported to us by Julio Garvia.
2960 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
2961 for the default, which the user can override.
2962 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
2963 deal with LEXLIB.
2964 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
2965 didn't work if some values were cached but not others. Test for
2966 broken lex libraries like native ia64-hp-hpux11.22; see
2967 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
2968 work around the problem by preferring an empty LEXLIB to -lfl or
2969 -ll. Let the user set LEXLIB='' to indicate no library needed.
2971 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
2972 * README: Likewise.
2973 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
2975 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>

3074 * doc/autoconf.texi (Particular Programs): Mention that
3075 @INSTALL@ and @MKDIR_P@ may vary for different output files.
3076 Reported by Alexandre Duret-Lutz.
3078 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
3080 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
3081 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
3082 Bill Northcott in
3083 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
3085 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>
3087 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
3088 pacify insanely picky compilers. Problem reported by Eric Blake.

3091 longer supported by Sun.
3093 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>

3096 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
3097 -Wundef -Werror". Problem reported by David Fang in
3098 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
3099 * doc/autoconf.texi (Header Templates, Default Includes):
3100 (Particular Functions, Generic Functions, Header Portability):
3101 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
3102 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):

3114 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
3115 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
3116 this.
3118 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
3120 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
3121 problems with arg script text that doesn't end in newline, and
3122 with '-e a...'. Problems reported by Ralf Wildenhues.
3124 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
3126 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
3127 check for libXt by a check for libX11.
3129 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3132 to last change.
3134 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3136 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
3137 --help' should mention that `--version' outputs configuration
3138 settings. Report by Bruno Haible.
3140 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
3142 Fix test suite failures reported by Pierre in
3143 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
3144 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
3145 the compiler created a file "b.out" when it didn't create anything
3146 at all.

3148 Discard stderr too, when invoking the test script.

3158 less skeptical about "volatile", after discussion with
3159 Bruno Haible on bug-gnulib.
3160 (Limitations of Usual Tools): Warn about sed stripping
3161 leading white space from text. From Bruno Haible.
3163 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
3165 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
3166 compiler complains about it, even if things works after the
3167 complaint. Problem reported by Peter O'Gorman.
3169 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
3170 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
3171 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
3173 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
3175 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
3176 after -R regardless of host. Patrick Welche reports that this
3177 fixes things on NetBSD 3.99.
3179 * NEWS: Recommend M4 1.4.5.
3180 * README: Likewise.
3181 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
3182 * tests/tools.at (autom4te cache): Update wording of diagnostic
3183 to match M4 1.4.5.
3185 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3187 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
3188 under AC_C_VOLATILE.
3189 (Volatile Objects): Be a little less skeptical about what
3190 "volatile" means. Derived from thoughts by Ben Pfaff in
3191 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
3193 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3195 * doc/autoconf.texi: Fix some typos.
3197 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3199 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3200 more globally, since the 2006-06-30 patch didn't suffice. Problem
3201 reported by Keith Marshall. Also, don't bother with builddir2,
3202 since it shouldn't be needed any more.
3204 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
3206 * doc/autoconf.texi (Generic compiler characteristics):
3207 Document AC_COMPUTE_INT. Fix wrong statements on Default
3208 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
3210 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
3211 (_AC_COMPUTE_INT): Add obsoletion warnings.

3221 * NEWS: Document previous change.
3223 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
3225 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
3226 Require that long long int be at least 64 bits wide. C99 requires
3227 this and enough programs depend on it so we should check for it.
3228 Bruno Haible reports in
3229 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
3230 that long long int is 32 bits wide with some nonstandard compilers.
3231 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
3233 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
3235 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3236 to a nonexistent file, so that we don't have to worry about
3237 a local site configuration that doesn't use /usr/local.
3238 Problem reported by Keith Marshall in
3239 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
3241 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
3243 * doc/autoconf.texi: Be more consistent about using @acronym with
3244 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
3245 quite right (it talked about "OSF/Tru64", even though the
3246 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
3247 and it even mentioned "OSF 4"!) and at this point there's little
3248 reason to talk about OSF any more, since it died in 1994.
3249 (Specific Compiler Characteristics): Simplify example of
3250 negative-size array.
3251 (File Descriptors): Reorder to make the text flow better.
3252 Remove joke about "appreciate the various levels"; I didn't get it.
3253 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
3254 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
3255 (File Descriptors, Limitations of Usual Tools):
3256 Tone down the advice against renaming or removing open files.
3257 (Limitations of Usual Tools): Add a new section, on 'rm'.
3259 2006-06-26 Stepan Kasal <kasal@ucw.cz>
3261 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
3262 -lXt in LIBS, idea from Karsten Hopp; this was due since
3263 this change:
3265 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3266 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3267 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3268 (which belong to Xt, not X itself). See Debian bug 327655.
3270 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3272 * configure.ac (AC_INIT): Bump to 2.60a.

3281 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3283 * config/texinfo.tex: Sync from upstream.
3285 * bin/autom4te.in (handle_traces): Transform the `@S|@'
3286 quadrigraph correctly in traces.
3288 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
3289 Fix typos.
3291 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
3292 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
3293 not defined.
3294 * doc/autoconf.texi (Changed Directory Variables): New node,
3295 to document the whole `datarootdir' business a bit better.
3296 * NEWS: Update.
3297 * tests/torture.at (datarootdir workaround): Extend test.
3298 Prompted by report by Alexandre Julliard.
3300 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
3302 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
3303 when using default mode of IBM C 6 for AIX. Problem and two-line
3304 fix reported by Larry Jones.
3306 2006-06-22 Alexandre Julliard <julliard@winehq.org>
3308 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
3309 about literal '${datarootdir}' if a definition is found in the
3310 output file.
3312 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
3314 * NEWS: Use "M4" rather than "m4" when appropriate.
3315 Problem reported by Eric Blake.
3316 * doc/autoconf.texi: Likewise.
3317 Use @acronym around BSD, GCC, and GNU when appropriate.
3318 (Why GNU M4): Renamed from "Why GNU m4".
3319 (Redefined M4 Macros): Mention that Posix
3320 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
3321 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
3322 to int.
3324 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3326 * bin/autom4te.in (handle_output): Do not forbid the empty
3327 pattern.
3328 * tests/tools.at (autoconf: the empty token): New test.
3330 2006-06-20 Stepan Kasal <kasal@ucw.cz>
3332 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
3333 calls, so that we do not care whether they are LIFO or FIFO;
3334 in the m4_wrap, do not check which diversion is the topmost
3335 one, just check that the stack is balanced at the end.
3336 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
3337 base diversion forever--pop the previous diversion before
3338 opening the new one; consequently, remove the m4_wrap call.
3339 * lib/autotest/general.m4 (AT_INIT): Likewise.
3340 * tests/m4sugar.at: Do not use
3341 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
3343 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
3344 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3346 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
3347 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
3348 Rework example of m4wrap token-pasting trouble so that it doesn't
3349 care whether it's LIFO or FIFO.
3350 Fix some "contrary to"s that are awkward in English.
3352 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3354 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
3355 to `yes' instead of `int$1_t' if the type is found, for more
3356 consistent configure output (where $1 is the number of bits).
3357 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
3358 Suggested by Bruno Haible.
3360 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
3361 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
3362 with system headers. Report by Bruno Haible.
3364 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3366 * config/config.guess, config/config.sub: Sync from upstream.
3368 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
3369 in order to avoid picking up an older installed frozen m4sh.m4f.
3370 Besides an outdated shell startup, this could have been created
3371 by an earlier M4 version with incompatible frozen file format.
3373 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
3375 * README: Recommend m4 1.4.4 instead of 1.4.3..
3376 * doc/autoconf.texi: Likewise.
3377 (Special Chars in Names): Say that $(.FOO) is portable, as
3378 suggested by Stepan Kasal.
3379 (Installation Directory Variables, Build Directories):
3380 (Automatic Remaking, Subdirectories, Fortran Compiler):
3381 (Making testsuite Scripts, Defining Directories):
3382 Quote variable usages better.
3383 (Making testsuite Scripts): Add clean-local rule to makefile
3384 snippet, by Eric Blake.
3385 (Installation Directory Variables): Fix table item font.
3386 Reword slightly to clarify. Generalize advice about
3387 not using special characters to include all file-related
3388 vars, not just VPATH.
3389 (Special Chars in Variables): Warn about special characters in
3390 $(srcdir) too.
3391 (Assignments): Clarify default-value example as suggested by
3392 Ralf Wildenhues in
3393 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
3394 (Special Shell Variables): Note leading ./ or ../, as suggested
3395 by Eric Blake.
3396 (Limitations of Builtins): Under cd, warn about CDPATH.
3397 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
3398 Ralf Wildenhues.
3400 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3402 * doc/autoconf.texi (Configuration Actions): Remove duplicate
3403 `@var', for texi2html.
3404 (Systemology): Some more word wrapping, for DVI output.
3405 (autom4te Invocation): The short option for `--melt' is `-M',
3406 not `-m'.
3408 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
3410 * doc/autoconf.texi: More formatting and English tweaks,
3411 many suggested by Ralf Wildenhues.
3412 Reword to avoid "@code{...}'s" and the like, since it's ugly
3413 with Emacs info mode. discontents -> woes.
3414 Put a few "will"s back. time stamp -> timestamp.
3415 side-effect -> side effect.
3417 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
3419 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
3420 Warn about $@ not persisting. Problem reported by Julien Danjou in
3421 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
3422 (Special Chars in Names): Renamed from Leading _ in Macro Names.
3423 Mention other special chars, too.
3425 2006-06-14 Eric Blake <ebb9@byu.net>
3427 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
3429 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
3431 * doc/autoconf.texi: Some systematic minor improvements, as
3432 follows. Use "makefile" when talking about makefiles
3433 generally (which might be named "makefile" or "Makefile" or even
3434 "foo.mk"), "Makefile" when talking about a specific makefile
3435 called "Makefile". This unclutters the text from weird quotes
3436 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
3437 values" rather than "@var{foo}s" and similar constructs containing
3438 "}s". Use "Make rules" rather than "Makefile rules". Minor
3439 English-language improvements. Change the prefix "sub-" to "sub"
3440 and "re-" to "re".
3441 Put blank lines around examples more consistently.
3442 Avoid "rather" and "very" as intensifiers.
3443 Avoid "will" as an auxiliary.
3444 (Limitations of Make): Split this node into....
3445 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
3446 (Leading _ in Macro Names, Backslash-Newline-Newline):
3447 (Backslash-Newline Comments, Long Lines in Makefiles):
3448 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
3449 (obj/ and Make, make -k Status, VPATH and Make):
3450 (VPATH and Double-colon, $< in Explicit Rules):
3451 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
3452 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
3453 New nodes, resulting from splitup of Limitations of Make.
3454 All cross-references changed. Raise the top node from
3455 a section to a chapter, and all subnodes accordingly.
3456 Redo the introductory wording to match the new organization.
3457 (Installation Directory Variables): Use an example that is
3458 closer to what Autoconf actually does. Mention that VPATH's
3459 value should not contain metacharacters or white space.
3460 (Fortran Compiler): Fix a VPATH bug in an example.
3461 (Leading _ in Macro Names): Mention that this problem is no longer
3462 of practical concern.
3463 (VPATH and Make): Reword the advice to make it clearer
3464 that Autoconf and Automake support VPATH in non-GNU make, but
3465 many packages have bugs in this area.
3466 ($< in Explicit Rules): Refer to Build Directories rather
3467 than using a (non-VPATH-safe) example.
3468 (Automatic Rule Rewriting): Mention the sort of disaster that
3469 can ensue with Solaris-style rule rewriting with VPATH.
3471 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3473 * doc/install.texi (Compilers and Options): Weaken the
3474 suggestion to use GNU make for VPATH builds.
3476 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
3477 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
3479 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
3480 in regular expression.
3482 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3484 * doc/autoconf.texi (Installation Directory Variables):
3485 Drop extra @samp from `@table @samp' item.
3486 (Limitations of Usual Tools): Comment fix.
3487 Do not nest @samp just to point to other table items.
3488 (Writing testsuite.at) <AT_CHECK>: The second argument to
3489 `@dvar' is already @samp'ed.
3490 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
3491 do not use @var in the second argument.
3493 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
3495 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
3496 $as_shell.exe too. Problem reported by Andreas Buening in
3497 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
3499 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3501 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
3502 `unused variable' compiler warning, for `-Wall -Werror'.
3503 Reported by Jaap Haitsma in
3504 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
3506 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
3508 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
3509 case the compiler dumps core. Problem reported for
3510 OpenServer 5.0.7 by Tim Rice in
3511 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
3512 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3513 Likewise.
3515 2006-06-06 Tim Rice <tim@multitalents.net>.
3517 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
3518 "ERROR" only shows up in "make check" output if there is an
3519 error.
3521 2006-06-06 Eric Blake <ebb9@byu.net>
3523 * tests/tools.at (automatically allowed tokens): Fix typo.
3525 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3527 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
3529 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
3530 typically overflows on x86 CPUs, even though the C standard
3531 requires otherwise.
3533 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3535 * configure.ac (AC_INIT): Bump to 2.59e.
3536 * NEWS: Update.
3538 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3540 Version 2.59d.
3542 * config/texinfo.tex: Sync from upstream.
3544 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
3545 seen, invoke libtoolize with `--ltdl' argument.
3546 * lib/autom4te.in (Autoreconf-preselections): Adjust.
3547 * NEWS: Update.
3548 Suggested by Eric Blake.
3550 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3552 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
3553 reported by Ralf Wildenhues.

3564 2006-06-05 Stepan Kasal <kasal@ucw.cz>
3566 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
3567 message issued by AC_REQUIRE.

3569 * tests/base.at: Check AC_REQUIRE's error message.
3570 * tests/local.at (AT_CHECK_M4): New macro, almost identical
3571 to...
3572 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
3573 AT_CHECK_M4.
3574 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
3575 `expout' as the last parameter.
3576 * tests/tools.at: Adapt to the above change.
3578 2006-06-04 Stepan Kasal <kasal@ucw.cz>
3580 * doc/autoconf.texi (Limitations of Usual Tools): Correct
3581 information about race-free implementations of mkdir.
3583 2006-06-04 Eric Blake <ebb9@byu.net>
3585 * bin/autoreconf.in (help): Document M4 environment variable.
3586 * bin/autoconf.as (Usage): Likewise.
3587 * bin/autom4te.in (help): Likewise.
3588 * doc/autoconf.texi (autom4te Invocation): Likewise.
3590 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
3592 * NEWS: GNU make now recommended for VPATH builds.
3593 Mention that some macros are now documented to be obsolescent.
3594 * doc/autoconf.texi:
3595 Prefer "current" to "modern" to describe
3596 currently-used (albeit perhaps old-fashioned) hosts.
3597 Mention which ancient features no longer need to be worried about.
3598 setgid -> set-group-ID
3599 setuid -> set-user-ID (these are the Posix terms)
3600 Fix some misuses of "only".
3601 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
3602 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
3603 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
3604 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
3605 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
3606 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
3607 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
3608 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
3609 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
3610 Mention that these macros are obsolescent.
3611 (Installation Directory Variables): shall -> should
3612 (File Descriptors): Mention that 0, 1, 2 might get reopened.
3613 Mention that it's now safe to use 3 and 4.
3614 (Limitations of Usual Tools): cp -r is now specified by Posix.
3615 Omit longwinded and obsolescent discussion of cp -f.
3616 Modernize discussion of expr, ls.
3617 (Limitations of Make): Modernize discussion of VPATH builds.
3618 Mention $? as a workaround in some cases.
3619 * doc/install.texi (Basic Installation):
3620 Mention "./configure; make; make install" first. Be more
3621 specific about why this file is generic. Remove unnecessary
3622 parens. Remove misleading "only". Remove obsolete advice
3623 about csh. Don't say "configure" takes awhile; say it
3624 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
3625 and CC=c99 rather than CC=c89, as these are blessed by current
3626 Posix. Recommend GNU make if doing a VPATH build.
3628 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
3630 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
3631 examples involving shell prompts.
3633 2006-06-02 Stepan Kasal <kasal@ucw.cz>
3634 and Paul Eggert <eggert@cs.ucla.edu>
3636 * doc/autoconf.texi (Here-Documents): Add details about the
3637 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
3638 use "here-documents" instead of "here documents".
3640 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3642 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
3644 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
3646 * doc/autoconf.texi (File System Conventions): Warn about ":"
3647 anywhere in directory names.
3649 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
3651 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
3652 about quoting the case statement, just in case.
3653 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
3654 was fixed in ksh93g; reported by Ralf Wildenhues.
3656 2006-05-31 Stepan Kasal <kasal@ucw.cz>
3658 * doc/autoconf.texi (System Services): Do not document
3659 overriding EXEEXT via ac_cv_exeext=ext.

3661 Document that ${MKDIR_P} understands --.
3662 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
3663 comment.
3665 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3667 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
3668 argument with leading hyphen. Problem reported by Paul Eggert.
3670 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3672 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
3673 about quoting ac_try: quote all of it, if any of it seems suspicious.
3674 This means we don't have to worry about ${ or sed any more.
3675 Also, double-quote the case statement, to work around misuses via
3676 underquoting as reported by Ralf Wildenhues in
3677 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
3678 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
3679 undocumented and dangerous macro.
3680 Problem reported by Ralf Wildenhues in
3681 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
3683 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3685 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
3686 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
3687 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
3689 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3691 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
3692 since evidently some packages rely on the old, broken behavior.
3693 Problem reported by Ralf Wildenhues in
3694 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
3695 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
3696 pre-2006-05-26 definitions, but leave in the comments that
3697 these macros are dangerous and should not be used.
3698 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
3699 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
3700 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
3701 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
3702 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
3704 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
3706 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
3707 the use of 'tr', since this is our only use of 'tr'.
3709 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3710 and Paul Eggert <eggert@cs.ucla.edu>
3712 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
3713 Don't assume 'grep' works on long lines, since AIX grep doesn't.
3715 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3717 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
3718 the output file in the `${datarootdir}' test.
3720 2005-05-28 Stepan Kasal <kasal@ucw.cz>
3721 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3723 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
3724 mention of `datarootdir' in the input file(s), but literal
3725 `${datarootdir}' in the output file, and we haven't warned yet,
3726 then warn as well: the user may have (erroneously) used
3727 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
3728 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
3729 * tests/torture.at (datarootdir workaround): Extend this test.
3730 * NEWS: Update.
3732 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3733 and Paul Eggert <eggert@cs.ucla.edu>
3735 * doc/autoconf.texi (autoheader Invocation): The first argument to
3736 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
3737 alternatives and clear up the language a bit.
3739 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
3741 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
3742 ac_config_guess, ac_config_sub, ac_configure.
3743 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3744 Fix typo that prevented an unnecessary space from being removed.
3745 Problems reported by Ralf Wildenhues in:
3746 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
3748 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
3750 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
3751 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
3752 Don't use the term "thread-safe" to talk about mkdir race
3753 conditions, since the problem is more a process than a thread
3754 issue. Problem reported by Stepan Kasal in:
3755 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
3756 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
3757 the test for 'install' more closely. Look at MKDIR_P first.
3758 Look in the PATH, and at /opt/sfw/bin.
3759 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
3760 Don't bother to try mkdir -p, since we already check mkdir --version;
3761 just look at the version number. (There's no easy way to check
3762 for race-free implementations.)
3763 * tests/tools.at (autoconf: subdirectories): Adjust to above
3764 changes, since MKDIR_P now might end in "/mkdir -p".
3766 * doc/autoconf.texi (autoheader Invocation): Mention that the
3767 first arg of AC_DEFINE_UNQUOTED must be a literal.
3768 Problem reported by Ben Pfaff in
3769 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
3771 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
3772 * doc/autoconf.texi (Special Chars in Variables): New section.
3773 (Preset Output Variables): Warn about special chars in CPPFLAGS.
3774 (Installation Directory Variables): Quote $(datadir) better.
3775 (Limitations of Builtins): Describe some of eval's trickiness.
3777 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
3778 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
3779 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
3780 in front of every arg, not just trailing args. Quote apostrophes.
3781 (_AC_EVAL_ECHO): New macro.
3782 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
3783 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
3784 removed.
3785 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
3786 exposed by quoting of eval argument. Put the command on line line
3787 so it logs better.
3788 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
3789 (_AC_PATH_X, AC_PATH_X): Quote more safely.
3790 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
3791 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
3792 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
3793 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
3794 Use eval more safely.
3795 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
3796 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
3797 to be replaced.
3798 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
3799 lines, exposed by quoting of eval argument.
3801 2006-05-26 Stepan Kasal <kasal@ucw.cz>
3802 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3804 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
3805 initialization of `ac_cv_exeext', do not override it if it was
3806 already set, unless it was set to `no', for compatibility with
3807 Autoconf-2.13, and comment this.
3808 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
3809 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
3810 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
3811 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
3812 Document that this test may be overridden by setting
3813 `ac_cv_exeext'.
3815 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3817 Revert these two patches:
3819 2006-04-06 Eric Blake <ebb9@byu.net>
3820 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3821 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3822 2006-04-01.
3824 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3825 Clean up _AC_COMPILER_EXEEXT* macros.
3826 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3827 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3828 ac_file to the name of the default output file and call
3829 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3830 initial `rm' of the candidate files...
3831 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3832 the same list in subsequent `rm' calls, and for the temporary
3833 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3834 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3835 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3836 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3837 no longer needed) by libtool. Make it a cache check.
3838 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3839 copied here by mistake.
3840 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3841 _AC_COMPILER_EXEEXT.
3842 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
3843 _AC_COMPILER_OBJEXT directly.
3844 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3846 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3848 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
3849 Fix description of how the buggy `sed' works.
3851 2006-05-25 Noah Misch <noah@cs.caltech.edu>
3853 Sync from Automake:
3855 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
3856 ENOLCK. Only mention `make -j' when applicable. Only raise
3857 fatal errors when `make -j' is involved. Improve error message.
3859 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3861 * doc/autoconf.texi (Here-Documents): We now know more about
3862 the variable expansion in here documents bug.
3863 Thanks to Tim Rice and Stepan Kasal.
3865 * doc/autoconf.texi (Making testsuite Scripts): Add an example
3866 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
3868 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3870 * tests/autotest.at (Multiline command from M4 expansion):
3871 No failure to be expected if the shell quotes newlines in
3872 commands in the `set -x' output. Report by Tim Rice.
3873 * THANKS: Update.
3875 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3877 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
3878 expansion in the here-documents used by config.status, as that
3879 runs afoul of the Korn shell version M-12/28/93d bug described in
3880 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
3881 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
3882 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
3884 2006-05-23 Jim Meyering <jim@meyering.net>
3886 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
3887 Fix typo introduced with 2006-04-02 change. It reversed the sense
3888 of the test.
3890 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3892 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
3893 ac_dB slightly, to save bytes in the script.
3894 Max out at 50 lines, rather than 96; this is more likely
3895 (though not guaranteed) to avoid obscure 'sed' failures.
3897 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3899 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
3900 `tr -d -' as bad option argument. Work around this by deleting
3901 an unrelated character.
3902 Report by Tim Rice <tim@multitalents.net>.
3904 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
3905 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3906 Stepan Kasal <kasal@ucw.cz>
3908 * doc/autoconf.texi (Particular Programs): Do not promise that
3909 we always prefer the GNU version of the program, and that we
3910 search according to PATH; both rules can have exceptions.
3911 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
3912 AC_PROG_SED. Move descriptions of limitations
3913 to the Limitations of Usual Tools section.
3914 (Limitations of Usual Tools) <sed>: Mention script length
3915 limitations with Solaris /usr/ucb/sed.
3916 <grep>: Fix wording for empty alternative. Mention that -c and
3917 -l should not be combined, and that -E and -F should not be
3918 combined.
3920 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3921 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3923 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
3924 limits in Solaris 8 /usr/ucb/sed by testing a long script.
3926 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3928 * doc/autoconf.texi (Defining Symbols): Literal parameter of
3929 AC_DEFINE is now passed to m4_pattern_allow.
3930 * NEWS: Mention that; likewise for AC_SUBST.
3931 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
3932 the parameter to m4_pattern_allow.
3933 * tests/tools.at: Add a check for that.
3935 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3937 * lib/autoconf/status.m4: Fix typos.
3939 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3941 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
3942 only the files that this macro generates.
3944 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3946 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
3947 the HP-UX sed limitation of 99 commands, labels do not count.
3948 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
3949 in the comment.
3950 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
3952 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3954 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3955 Import the following fix from coreutils:
3957 2006-01-13 Jim Meyering <jim@meyering.net>
3959 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
3960 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
3961 not double-quote uses of that variable, to accommodate the rare
3962 case in which getmntent is available in none of the libraries
3963 checked. This happens at least on FreeBSD 5.0.
3965 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
3967 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
3968 ac_config_guess, ac_config_sub, and ac_configure, since evidently
3969 some other programs unwisely rely on these undocumented vars.
3970 But put in warning comments about them.
3971 Problem reported by Ralf Wildenhues in
3972 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
3973 * NEWS: Document that these variables are intended to go away.
3975 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3977 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
3978 and set the language to C++ (analogous to the equivalent Fortran
3979 tests).
3981 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
3982 * doc/autoconf.texi (C++ Compiler): Document it.
3983 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
3984 * NEWS: Update.
3986 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
3988 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
3989 that caused config.status to generate 100-command sed scripts; the
3990 portable limit is 99.
3992 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3994 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
3995 variable `ac_d' instead of `d' to avoid infringing namespace.
3996 Report by Ralf Menzel.
3998 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
4000 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
4001 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
4002 * tests/tools.at (autoconf: subdirectories): New test, taken from
4003 the corresponding problem report by Ralf Wildenhues in:
4004 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
4006 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
4007 Quote some uses of shell variables if they might suffer unexpected
4008 globbing. This doesn't fix all instances of quoting problems that
4009 I found, just the easy ones that look safe.
4010 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
4011 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
4012 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
4013 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
4014 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
4015 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
4016 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
4017 Likewise.
4018 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
4019 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
4021 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4023 * bin/autoreconf.in ($help): Reword according to the manual.
4024 Suggested by Olly Betts.
4026 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
4027 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4029 * bin/autoreconf.in: Pass the directory argument to
4030 `require_configure_ac'. Fix comment.
4031 * tests/torture.at (Configuring subdirectories): Expose this.
4032 Reported by Olly Betts.
4034 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4036 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
4037 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
4038 Automake as follows:
4040 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
4041 `$configure_in' instead of `configure.in', to preserve
4042 directory component.
4044 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4046 * config/config.guess, config/config.sub, config/texinfo.tex,
4047 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
4049 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
4051 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
4052 test for C99 conformance; (bool) 0.5 is an integer constant
4053 expression, but (bool) -0.5 is not. Problem reported by Fedor
4054 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
4056 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
4058 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
4059 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
4060 Warn about obsolete install-sh files. Remove stray sentence
4061 fragment and fix cross reference.
4062 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
4063 install -d; this undoes the 2006-05-10 change.
4064 (MKDIR_P): Mark with AN_MAKEVAR.
4065 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
4066 that we don't require $INSTALL to be thread-safe. Move comments
4067 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
4068 of AC_PROG_INSTALL. Output a message saying that we're checking
4069 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
4070 MKDIR_P instead of AC_SUBST.
4071 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
4072 Special magic for MKDIR_P, too.
4073 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
4074 a dnl.
4075 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
4077 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
4079 Sync from Automake, as follows:
4081 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4082 * config/install-sh: Initialize IFS, so field splitting isn't
4083 turned off later.
4084 * config/mkinstalldirs: Likewise.
4085 * config/missing: Remove superfluous quotes. Replace all uses of
4086 `[' by `test', for consistency, and for..
4087 * config/missing (sed_minuso, sed_output): New variables.
4088 (autom4te, help2man, makeinfo): Use them. Unifies detection of
4089 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
4090 Fixes `missing' to detect `--output' for help2man. Fixes
4091 PR automake/483. Report by Dennis J. Linse.
4092 (autom4te): Document in `missing --help'.
4094 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4096 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
4097 * config/install-sh: Don't use 'path' to talk about file names,
4098 as per GNU coding standards. Close a race condition reported by Ralf
4099 Wildenhues and Stepan Kasal. There is still a race condition
4100 on hosts that predate Posix 1003.1-1992, but we can't help this.
4101 Don't mishandle weird characters like space on pre-Posix hosts.
4102 Invoke mkdir at most once per dir arg on pre-Posix hosts.
4103 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
4104 AC_PROG_MKDIR_P from AS_MKDIR_P.
4105 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
4106 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
4107 earlier editions are not (including Automake 1.8.3).
4108 Do not suggest mkinstalldirs for thread-safety.
4109 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
4110 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
4111 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
4112 presence of special characters and race conditions.
4113 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
4114 in Autoconf's name space.
4116 2006-05-10 Bruno Haible <bruno@clisp.org>
4117 and Paul Eggert <eggert@cs.ucla.edu>
4119 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
4120 from Automake with minor changes.
4121 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
4123 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4125 * config/install-sh: Update to Automake CVS version, as follows:
4126 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4127 * lib/install-sh: Simplify the expr implementation of dirname.
4128 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
4129 * lib/install-sh: Handle --, and diagnose unknown options.
4131 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4133 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
4134 `./autom4te' to create `./testsuite', since the `all' target
4135 will ensure its presence, but `installcheck' should not create
4136 the uninstalled wrappers.
4138 * tests/torture.at (Unusual Automake input files): Skip if we
4139 detect automake < 1.8.
4141 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4143 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
4144 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
4145 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
4146 * NEWS: Update.
4148 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4150 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
4151 munge (multiple) white space and other oddities.
4152 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
4153 single quotes in variable assignment.
4154 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
4155 and similar failures by adding multiple spaces, tabs, and other
4156 special characters.
4157 Report and different test suggested by Francesco Romani
4158 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
4160 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
4161 single quotes, we only need to search for single quotes; this
4162 both simplifies the search pattern, and makes us less
4163 susceptible to `echo' variations for arguments not containing
4164 single quotes.
4165 (_AC_ARG_VAR_VALIDATE): Likewise.
4167 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4169 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
4170 `$*' and IFS concatenation issue with traditional shells and

4182 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4183 and Bruno Haible <bruno@clisp.org>
4185 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
4186 about 'od'.
4187 (Integer Overflow): Mention the special case of integer division
4188 overflow.
4190 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4192 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
4193 traditional shells like the Solaris one that do not use the
4194 first IFS character for assembling `$*'.
4195 Prompted by a related report from autoconf_bug@nro.ca.
4197 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
4198 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4200 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
4201 Mention more problems with the -e option.
4203 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4215 continuous text.
4216 (Runtime): Fix macro argument names to match description:
4217 `action-if-found' -> `action-if-true' and similarly.
4218 (Obsolete Macros): Likewise.
4219 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
4220 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
4221 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
4223 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4225 * doc/autoconf.texi (Limitations of Make): Clean up markup.
4227 * ChangeLog: Typo.

4244 with status 1, not merely nonzero. Clarify exit declaration.
4245 (Run Time): Move C exit status stuff to new Exiting Portably section.
4246 (Systemology): Mention Posix and levenez. Update v7 reference.
4247 (Portable Shell): Mention the Posix shell.
4249 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4251 * bin/autoconf.as (me): Replace by as_me.
4253 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
4255 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
4256 since as_me isn't set yet.
4258 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4260 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
4261 a few minor bugs in this area.
4263 * doc/autoconf.texi (Programming in M4sh): Comment out the
4264 documentation of AS_BASENAME, for now.
4265 (Shell Substitutions): Do not use AS_DIRNAME in an example.
4266 (Limitations of Builtins) <basename>: Do not refer to
4267 AS_BASENAME.
4268 * bin/autoconf.as (me): Don't use AS_BASENAME.
4269 (dir): Remove the unused variable.
4270 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
4271 AS_DETECT_REQUIRED. All uses changed.

4276 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
4277 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
4278 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
4279 (_AS_DIRNAME_PREPARE): Likewise.
4280 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
4281 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.

4284 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4286 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
4287 of "run time" and "run-time" changed to "runtime", for consistency.

4289 * lib/autoconf/functions.m4: Likewise.
4290 * lib/autoconf/general.m4: Likewise.
4291 * lib/autoconf/headers.m4: Likewise.
4293 * doc/autoconf.texi (Run Time): Document the exit status situation
4294 with more accuracy and detail.
4296 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4298 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
4299 Archive is not officially `GNU' any more. Update URL.
4300 (Defining Directories): Likewise
4301 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
4303 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4305 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
4306 newline from the `trap' code to finish `config.log'; the NetBSD
4307 /bin/sh resets the exit status after an empty command, as
4308 documented in doc/autoconf.texi.
4309 Reported by Dalibor Topic <robilad@kaffe.org>.
4311 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
4313 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
4314 Suggested by Bruno Haible.
4316 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
4318 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
4319 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
4320 Instead, just list the shells that we know work.
4321 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
4322 changed. Be more cautious about the _cv_ variable.
4323 * tests/tools.at (Syntax of the shell scripts): Check the
4324 _cv_ variable once, at first, to avoid an internal autoconf error
4325 when sh -n does not work.
4327 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4329 * lib/Autom4te/FileUtils.pm: Sync from Automake.
4331 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
4333 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
4334 use ">&-" since we're only 99.999% sure that this is portable,
4335 and since the MinGW bug is fixed in a different way.
4336 * lib/autotest/general.m4 (AT_INIT): Likewise.
4338 2006-04-16 Stepan Kasal <kasal@ucw.cz>
4340 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
4341 before opening config.log, to avoid hitting a bug on MinGW.
4343 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
4345 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
4346 AS_MESSAGE_LOG_FD before reopening it onto the log file.
4347 This works around a MinGW bug reported by Eric Paire.
4348 Make sure that all writes to the log file append to it,
4349 rather than possibly losing data.
4350 * lib/autotest/general.m4 (AT_INIT): Likewise.
4352 2006-04-14 Stepan Kasal <kasal@ucw.cz>
4354 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
4355 description.
4357 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4359 * NEWS: Update.
4361 * configure.ac (AC_INIT): Bump to 2.59d.
4363 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4365 Version 2.59c.
4367 * Makefile.maint (news-date-check): Do not require a leading `*'
4368 before the release date in NEWS.
4370 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4371 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4373 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
4374 the instantiated file do not contain the string 'datarootdir'
4375 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
4376 @mandir@, replace the reference '${datarootdir}' by the value.
4377 * tests/torture.at (datarootdir workaround): New test.
4378 * NEWS: Advertise this temporary fixup.
4379 Based on a patch by Bruno Haible, reported and analyzed by
4380 Paul Eggert and Noah Misch.
4382 2006-04-12 Eric Blake <ebb9@byu.net>
4384 * tests/autotest.at (Debugging a failed test): Fix comment.
4386 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4388 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
4389 all the changes since 2006-04-07.
4391 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4393 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
4394 succeeded, but `ln -s file dir' failed, take care to remove the
4395 leftover target before the next test, to prevent its spurious
4396 failure; also make sure `ln file dir' works before selecting it.
4397 Thanks to Keith Marshall for pointing this out.
4398 * THANKS: Update.
4400 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
4401 assignments in `at_debug_args', so that we put them correctly
4402 in the `run' script.
4403 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
4404 Reported by Eric Blake.
4406 2006-04-11 Eric Blake <ebb9@byu.net>
4408 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
4409 top-level tests after micro-suite has been run. Used in...
4410 (Debugging a successful test, Debugging script and environment),
4411 (Debugging a failed test): ...these new tests. The first of these
4412 is fixed by...
4413 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
4414 macro, split out from...
4415 (AT_INIT): ...here, so that using -d also generates a run script.
4416 Document that -d inhibits top-level logging.
4417 * doc/autoconf.texi (testsuite Invocation): Document that -d only
4418 inhibits top-level logging; debug scripts are created.
4420 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
4421 check.
4422 * tests/autotest.at (Empty test, Empty check): New test to check it.
4424 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
4425 from gcc.
4427 2006-04-10 Stepan Kasal <kasal@ucw.cz>
4429 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
4430 the files if a problem appears. Make the empty *.at files
4431 read-only, too. Proposed by Ralf Wildenhues.
4433 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4435 * config/Makefile.am: Add comment to force updated Makefile.in.
4437 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
4438 space only patch to this file, this patch causes the Makefile.in
4439 files that include freeze.mk to be updated, and thus have a
4440 newer time stamp again, which in turn makes a pristine CVS
4441 checkout have correct time stamps.
4443 * Makefile.maint (cvs-sv): New macro, to be used..
4444 (config.guess-url_prefix, config.sub-url_prefix)
4445 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
4446 point to CVS text checkout of Gnulib files.
4447 (copyright-check): Bump current year.
4448 (announcement): Do not hard-wire `./announce-gen'.
4449 (cvs-update): Propagate failures of `cvs' and `move-if-change'
4450 correctly.
4451 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
4452 `chmod +x'.
4453 (wget_files): Update config.guess, config.sub, texinfo.tex by
4454 `wget-update', now that their URLs work again.
4456 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4458 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
4459 Problem noted by Paul D. Smith.
4461 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4463 * doc/autoconf.texi: Remove unused words from word list.
4464 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
4465 .x-sc_trailing_space: New files.
4467 * doc/standards.texi: Sync from gnulib.
4469 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
4470 `LIBOBJDIR' as experimental.
4472 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
4473 with a target directory; it's internally implemented as `cp'
4474 anyway, but since Autoconf advertises the possibility to use
4475 a target directory when LN_S is `ln -s', we need to find out.
4476 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
4477 analyzed by Keith Marshall <keith.marshall@total.com>.
4479 * THANKS: Update.
4481 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4483 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
4484 confdefs.h as-is. In general, if it has backslash-newline or the
4485 like, then it doesn't work either to sort or to remove empty
4486 lines.
4488 2006-04-09 Stepan Kasal <kasal@ucw.cz>
4490 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
4492 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
4494 * lib/autom4te.in (Automake-preselections): Preselect
4495 _AM_SUBST_NOTMAKE.
4497 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4499 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
4500 apostrophe within a single-quoted string, as this is the usual
4501 tradition and is easier to read than '"'"'. Don't rely on the
4502 shell treating "$/" like '$/'. Use a more-consistent indenting
4503 style for the trap.
4505 2006-04-09 Eric Blake <ebb9@byu.net>
4507 * tests/autotest.at (Backquote command substitution),
4508 (Multiline backquote command substitution): Remove mistaken
4509 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
4510 applied...
4511 (Parenthetical command substitution, Multiline parenthetical
4512 command substitution): here.
4514 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4516 Import macros from gnulib (often changing their name).
4518 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

4530 (Pointers): Add Gnulib URL.
4531 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
4532 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
4533 Gnulib section.
4534 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
4535 suggest a #define rather than a typedef for _Bool, and mention
4536 Gnulib rather than trying to substitute stdbool code.
4537 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
4538 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
4539 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

4542 headers too.
4543 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
4544 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
4545 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
4546 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
4547 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
4548 (C Compiler): Move AC_C_LONG_DOUBLE to ...
4549 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
4550 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
4551 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
4552 (Coding Style). Don't mention m4_expand_once.

4560 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
4561 (AC_HEADER_ASSERT): New macro.
4562 (AC_HEADER_STDBOOL): Don't assume "#error" works.
4563 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
4564 Catch a bug in an HP-UX C compiler.
4565 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
4566 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

4570 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
4571 New macros.
4573 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
4574 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
4576 2006-04-08 Stepan Kasal <kasal@ucw.cz>
4578 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
4579 of the warning introduced by the 2001-08-28 change.
4581 2006-04-08 Stepan Kasal <kasal@ucw.cz>,

4589 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4591 Revert the patch from 2006-04-01 and only improve
4592 _AS_DETECT_BETTER_SHELL:
4594 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
4595 skip nonexistent directories.
4596 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
4597 only shell candidates which exist.
4598 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
4599 * lib/autotest/general.m4 (AT_INIT): No need to give three
4600 parameters to _AS_PATH_WALK.
4602 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
4603 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4605 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
4606 distinguish m4sugar macros.
4607 * tests/tools.at (autoupdating with aclocal and m4_include):
4608 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
4609 test case by Noah Misch <noah@cs.caltech.edu>.
4611 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4613 Revert my change from 2006-03-17, in other words:
4614 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
4615 and DUALCASE=1.
4616 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
4617 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
4618 it is set.
4620 2006-04-07 Eric Blake <ebb9@byu.net>
4622 * doc/autoconf.texi (Programming in M4sh): Document that
4623 AS_MKDIR_P exits the script on failure.
4624 * lib/autotest/general.m4: Remove redundant AS_ERROR.
4626 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4628 * config/elisp-comp, config/install-sh, config/mdate-sh,
4629 config/missing, config/mkinstalldirs: Sync from Automake.
4631 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
4632 from Automake.
4634 * doc/make-stds.texi: Sync from gnulib.
4636 2006-04-06 Eric Blake <ebb9@byu.net>
4638 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4639 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4640 2006-04-01.
4642 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
4643 Eric Blake <ebb9@byu.net>,
4644 Paul Eggert <eggert@cs.ucla.edu>,
4645 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4647 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
4648 whether `set' quotes correctly: redirect stderr of the tested
4649 `set', and use a subshell, for Ultrix; use `sed' instead of
4650 `grep' for zsh `set' which may write binary output; match only
4651 at the beginning of a line, to avoid false positives.
4652 In order to avoid false positives by unrelated variables with
4653 multiline content, put the dump algorithm in a subshell and
4654 unset all variables containing newlines (except some which are
4655 special to the shell). Warn about cache variables that are
4656 unset.
4658 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4660 * config/config.guess, config/config.sub, config/texinfo.tex:
4661 Sync from upstream.
4663 * tests/mktests.sh: Reword comments.
4665 * tests/mktests.sh: Only skip internal macros starting with
4666 `_AC_' or `__AC_'. Noted by Stepan Kasal.
4667 Update exclusion lists for the test suite to this end:
4668 (AC_ARG_VAR): Do test this now.
4669 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
4670 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
4671 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
4672 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
4674 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
4675 shell issue with double-quoted command substitutions of native
4676 commands.
4677 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
4678 Marshall.
4680 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
4681 no file matches the glob, discard the warning, set `nullglob'.
4682 (syntax-check): Likewise.
4683 (sc_cast_of_x_alloc_return_value): Likewise.
4684 (sc_cast_of_alloca_return_value, sc_error_exit_success)

4688 (sc_tight_scope): Do not fail for non-existing `src' directory.
4689 (sc_changelog): Skip the Copyright footer.
4690 * lib/autoconf/lang.m4: Remove trailing space.
4692 * lib/autoconf/status.m4: More replacements to
4693 <tab><space> where this makes sense.
4695 2006-04-06 Stepan Kasal <kasal@ucw.cz>
4697 * tests/Makefile.am (maintainer-check-posix):
4698 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
4700 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
4701 ac_config_<foo>s again, sometimes normalized, sometimes not.
4702 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
4703 (AC_CONFIG_COMMANDS): Do not do so here.
4704 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
4705 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
4706 2005-07-25 rewrite. Noticed by Noah Misch.
4708 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
4709 _AC_PRESERVE_HELP_ORDER, ...
4710 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
4712 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
4713 inside m4_expand_once; it is redundant.
4715 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
4716 for --help from Cygnus `configure.'
4718 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
4720 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
4721 on a patch proposed by Ralf Wildenhues.
4723 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
4725 * lib/autoconf/status.m4: Replace <space>''<tab> with
4726 <tab><space> where this makes sense.
4728 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
4729 Noah Misch <noah@cs.caltech.edu>
4731 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
4732 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
4733 * doc/autoconf.texi (Help Formatting): New node.
4734 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
4736 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4738 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
4739 lib/autoconf/specific.m4, lib/autoconf/status.m4,
4740 lib/autoconf/types.m4, lib/autotest/general.m4,
4741 tests/mktests.sh, tests/torture.at: White space cleanup:
4742 remove some SPACE before TAB, or add quoting ('' or @&t@).
4744 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
4746 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
4748 2006-04-05 Eric Blake <ebb9@byu.net>
4750 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
4751 empty test suite works.
4752 * tests/autotest.at (Empty test suite): Remove xfail.
4754 2006-04-05 Noah Misch <noah@cs.caltech.edu>
4756 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
4757 TAGS to ac_config_<foo>s.
4758 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
4759 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
4760 normalizing it, consistent it with previous releases.
4761 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
4763 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
4765 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
4766 Use simplified args that Eric Blake originally suggested.
4768 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
4770 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
4771 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
4772 Use 'comm' rather than N instances of grep; this also fixes a bug
4773 whereby substrings were incorrectly matched, causing us to not
4774 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
4775 (exclude_list): Exclude empty macros.
4776 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
4778 Use awk rather than grep -E or egrep, to avoid
4779 portability problems with regular expressions containing newlines.

4781 Switch from grep to awk syntax.
4782 (ac_exclude_script): Renamed from ac_exclude_egrep.
4783 (au_exclude_script): Renamed from au_exclude_egrep.
4785 2006-04-04 Noah Misch <noah@cs.caltech.edu>
4787 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
4788 a subdirectory subject to Cygnus `configure'.
4789 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
4791 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
4792 report request when we have no AC_PACKAGE_BUGREPORT.
4794 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4796 * THANKS: Update.

4799 generated files.
4801 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
4802 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
4803 typedef'ed restricted pointer, to catch a compiler bug on
4804 HP-UX 11.x, and fix warnings so it passes with -Werror.
4805 (_AC_PROG_CC_C99): Likewise.
4806 Reported by Albert Chin <china@thewrittenword.com>.
4807 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

4822 * THANKS: Add myself.
4824 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4826 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
4827 to log, point to testsuite output tree.
4829 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
4831 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
4832 * doc/autoconf.texi (Function Portability): Mention that C++
4833 has trouble with 'exit'.

4836 Remove; all uses removed.
4837 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

4857 Clean up _AC_COMPILER_EXEEXT* macros.
4859 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4860 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4861 ac_file to the name of the default output file and call
4862 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4863 initial `rm' of the candidate files...
4864 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4865 the same list in subsequent `rm' calls, and for the temporary
4866 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4867 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4868 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4869 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4870 no longer needed) by libtool. Make it a cache check.
4871 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4872 copied here by mistake.
4873 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4874 _AC_COMPILER_EXEEXT.
4875 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
4876 _AC_COMPILER_OBJEXT directly.

4903 and fix some typos.
4905 2006-04-01 Noah Misch <noah@cs.caltech.edu>
4907 * lib/autoconf/general.m4 (_AC_INIT_VERSION): Emit script name and
4908 Autoconf version number despite a zero- or one-argument AC_INIT.
4910 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
4911 subordinate tools.
4912 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
4913 * doc/autoconf.texi (autoreconf Invocation): Document it.
4915 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
4916 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

4922 rm failed to remove it.
4924 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4926 * bin/autoupdate.in: Redefine m4_location so that warnings print
4927 the correct lines of the input file by subtracting..
4928 (_au__first_line): ..this new definition.
4930 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
4931 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
4932 Remove stray newline in output.
4933 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
4934 AC_DEFUN this for autoconf, including the obsoletion diagnose.
4935 Fixes autoupdating of code where the replacement output contains
4936 m4sugar macros.
4937 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
4938 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

4940 * tests/tools.at: Several new tests for all of this.
4941 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
4942 hairy details.
4943 The AC_LANG_SAVE issue was reported against Libtool by
4944 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
4945 Kristian Kvilekval <kris@cs.ucsb.edu>.
4947 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4949 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
4950 switch all of them on and of when necessary. Fixes the bug when
4951 m4sugar macros (e.g., m4_define) were expanded after the first
4952 automatic update (e.g., after AC_PREREQ or AC_INIT).
4954 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

4976 2006-03-30 Chris Pickett <cpicke@cs.mcgill.ca> (tiny change)
4978 * doc/autoconf.texi (autoreconf Invocation): Mention that -I for
4979 aclocal cannot be given on the command line.
4981 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
4983 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
4984 Give an example for AS_DIRNAME instead of referring to Posix..
4985 (File System Conventions): Put discussion of // versus / here, and
4986 modernize it a bit.
4987 (Limitations of Usual Tools): Add basename. Remove verbiage
4988 after dirname, since it got moved to the above sections.
4989 All this was inspired by a patch proposed earlier by Eric Blake.
4991 2006-03-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4993 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Quote

4997 `$0', $as_me.
4999 2006-03-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5001 * bin/autoscan.in: The value of find_configure_ac should be
5002 checked for existence, so we don't barf over a nonexisting
5003 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
5005 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5007 * bin/autoupdate.in: Fix some typos.
5009 2006-03-21 Stepan Kasal <kasal@ucw.cz>
5011 * doc/autoconf.texi (Installation Directory Variables): Fix typo.
5013 * lib/autoscan/autoscan.list: Refreshed.
5015 2006-03-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5502 (Limitations of Usual Tools): Document the weird restrictions
5503 that Posix has about { }. Use better quoting.
5504 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_HEADER):
5505 Rewrite to conform to Posix rules about { } in sed scripts.
5506 * lib/m4sugar/m4sh.m4 (AS_DIRNAME_SED, AS_BASENAME_SED): Likewise.
5507 * tests/foreign.at (Libtool): Likewise.
5508 * tests/semantics.at (AC_CHECK_PROG & AC_CHECK_PROGS):
5509 Use our own style advice re 's,a,b,' versus 's|a|b|'.

5524 shell from zsh to bash.
5526 2005-12-31 Stepan Kasal <kasal@ucw.cz>
5528 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Use $PATH_SEPARATOR;
5529 ":" caused problems on OS/2-EMX. Suggested by Andrew Belov.
5531 2005-12-29 Paul Eggert <eggert@cs.ucla.edu>
5533 * doc/autoconf.texi (Shell Substitutions): Warn about unbalanced
5534 parentheses in $(...). Problem reported by Eric Blake.

5564 2005-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5566 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Pass
5567 CONFIG_SHELL in the environment of the configure rerun.
5568 * doc/autoconf.texi (Here-Documents, config.status Invocation):
5569 Suggest passing CONFIG_SHELL absolute, and in the environment
5570 rather than as option.
5572 2005-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5574 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

5588 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5590 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
5591 Factor functionality to..
5592 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
5593 `AC_SUBST($1)' in the public version.
5594 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
5595 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
5596 ac_pt_* variables.
5598 2005-11-01 Stepan Kasal <kasal@ucw.cz>
5600 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
5601 filesystems.
5603 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5607 2005-10-27 Stepan Kasal <kasal@ucw.cz>
5609 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
5610 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
5612 2005-10-25 Stepan Kasal <kasal@ucw.cz>
5614 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
5615 conftst2.$ac_objext.
5616 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
5618 2005-10-24 Stepan Kasal <kasal@ucw.cz>
5620 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
5621 conftest.o, to see whether the compiler really obeys; rm the object
5622 file before and after the test and register it with ac_clean_files.
5623 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
5625 2005-10-21 Stepan Kasal <kasal@ucw.cz>
5627 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
5628 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
5629 code so that the most common case requires less forks.
5631 2005-10-20 Stepan Kasal <kasal@ucw.cz>
5633 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
5634 not portable; thanks to Paul Eggert and Alexandre.
5636 * NEWS: Fix an old typo.
5638 2005-10-20 Jim Meyering <jim@meyering.net>

5641 the latter'', in two places.
5643 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
5645 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
5646 AC_LANG_PROGRAM, fixing a typo. Don't give details about
5647 the inner workings of AC_LANG_FUNC_LINK_TRY.
5648 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
5649 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
5650 by the function rather than ignoring it.
5651 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
5652 comparing its address. Intel's interprocedural optimization was
5653 outsmarting the old heuristic. Problem reported by
5654 Mikulas Patocka.
5656 2005-10-19 Stepan Kasal <kasal@ucw.cz>
5658 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
5660 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
5662 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

5665 2005-10-04 Stepan Kasal <kasal@ucw.cz>
5667 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
5668 before removing it (chmod -R u+rwx); there are three instances of this.
5670 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5671 Stepan Kasal <kasal@ucw.cz>
5673 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
5674 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
5675 make its content writable before removing it. Remove an errorneous
5676 comment from the end, where the logs of the failed tests are copied
5677 to the main log file.
5679 2005-09-27 Stepan Kasal <kasal@ucw.cz>
5681 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
5682 in case the computer is too quick. Double quote the configure.ac
5683 snippets.
5685 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
5686 problems if the testsuite were running too fast.
5688 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5690 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5691 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5692 (which belong to Xt, not X itself). See Debian bug 327655.
5693 * NEWS: Mention this.
5695 2005-09-07 Stepan Kasal <kasal@ucw.cz>
5697 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
5699 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
5701 * config/move-if-change: Don't output "$2 is unchanged";
5702 suggested by Ben Elliston. Handle weird characters correctly.
5704 2005-09-06 Stepan Kasal <kasal@ucw.cz>
5706 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
5707 calls, so that the final expansion of this macro is shorter.
5708 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
5709 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
5710 the cleanup there. Use AS_VAR_* macros, to be more general.
5711 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
5713 * lib/autoconf/general.m4: Use AS_IF where appropriate.
5715 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
5717 2005-09-01 Stepan Kasal <kasal@ucw.cz>
5719 * doc/autoconf.texi (Configuration Headers): Add an index entry
5720 for AH_HEADER.
5722 2005-08-26 Pavel Roskin <proski@gnu.org>
5724 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
5725 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
5726 running xmkmf.
5728 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
5730 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
5731 The previous patch didn't work, so try a better one.
5733 2005-08-26 Stepan Kasal <kasal@ucw.cz>
5735 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
5736 in the example. Reported by Bruno Haible.
5737 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
5738 "if $undefined_var;" succeeds with my shell.
5740 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
5741 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
5742 but change the m4_divert_text to m4_divert_once.
5744 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
5746 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
5747 Work around bug in Solaris /usr/xpg4/bin/awk.
5748 The bug is present in at least Solaris 8 through 10.
5750 2005-08-24 Stepan Kasal <kasal@ucw.cz>
5752 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
5753 some evil values and relying on the fact that $* concatenates the
5754 parameters by the first character from IFS.
5756 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5757 Stepan Kasal <kasal@ucw.cz>
5759 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
5760 first header appears, define AH_HEADER.
5761 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
5762 Update limitations about when to call AC_CONFIG_HEADERS.
5763 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
5764 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
5765 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
5766 ``Configuration Actions''; fix their index entries.
5768 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
5769 options correctly. Process N-M as M-N if M is smaller than N.
5770 Process ranges correctly so that N-N will run only N.
5771 Sort and uniquify the tests that will be run. If there is more
5772 than one test, reinsert the banners for the tests.
5773 * tests/autotest.at (Keywords): Unmark XFAIL.
5775 2005-08-23 Stepan Kasal <kasal@ucw.cz>
5777 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
5778 before passing the macro name to AH_TEMPLATE.
5780 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
5781 now opens log after option processing; in particular, --version
5782 and --help do not touch config.log.
5784 * Makefile.maint: Revert the change from 2005-08-12.
5786 2005-08-22 Stepan Kasal <kasal@ucw.cz>
5788 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
5789 common code to...

5794 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
5795 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
5796 Language cleanup.
5798 * doc/autoconf.texi (Defining Symbols, Changed Results):
5799 Prepend to LIBS, not append, in examples.
5801 2005-08-16 Stepan Kasal <kasal@ucw.cz>
5803 When building in place, set srcdir="."; suggested by Tim Van Holder.
5805 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
5806 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
5807 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
5808 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
5809 does not mean "no --srcdir option".
5811 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5813 * tests/autoscan.at (autoscan): New file.
5814 * tests/suite.at: Use it.
5815 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
5816 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
5818 * tests/autotest.at (Keywords): Test keywords combinations.
5820 2005-08-12 Stepan Kasal <kasal@ucw.cz>
5822 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
5823 add "2>&1"; gzip 1.2.4 prints help on stderr.
5825 2005-07-27 Stepan Kasal <kasal@ucw.cz>
5827 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
5828 was pushdef'ed twice while popped only once. Push it only once.
5829 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
5831 2005-07-26 Stepan Kasal <kasal@ucw.cz>
5833 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
5834 prefixed by mere "===", not "configure: === ".
5836 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
5838 * Makefile.maint: Update from Bison.
5840 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
5841 "<tab>" in comment, so that the point is understandable.
5843 2005-07-25 Stepan Kasal <kasal@ucw.cz>
5845 Rewrite substantial part of lib/autoconf/status.m4.
5846 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
5847 and CONFIG_COMMANDS are not processed in four separate loops.
5848 Instead, there is one main loop. This alows that the common code
5849 is expanded only once, thus config.status (and configure) is smaller.
5851 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
5852 the AC_LIST_FILES and cousins macros are no longer used.
5854 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
5855 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
5856 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
5857 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
5858 contain the initialization, nor the for loop, nor the associated
5859 commands; all these go to ...
5860 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
5861 _AC_OUTPUT_CONFIG_STATUS.
5862 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
5863 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
5864 (_AC_OUTPUT_FILE): The creation of the sed script ...
5865 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
5866 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
5867 _AC_OUTPUT_MAIN_LOOP.
5868 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
5869 _AC_CONFIG_COMMANDS): Use ...
5870 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
5871 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
5872 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
5873 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
5874 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
5875 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
5876 ... new macros.
5877 (_AC_CONFIG_UNIQUE): Update.
5878 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
5879 Replaced by this ...
5880 (_AC_LIST_TAGS): ... new common macro.
5881 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
5882 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
5883 (_AC_LIST_TAG_COMMANDS): ... new common macro.
5884 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
5885 this didn't belong to the `config commands' section.
5886 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
5887 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
5888 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
5889 to the `config commands' section either.
5890 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
5891 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
5893 ... and many changes to the comments nearby.
5895 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
5896 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
5897 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5898 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
5899 (#define header templates): The comment at the top of the generated
5900 header now includes the name(s) of the source file(s).
5902 Several unrelated small changes:
5904 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
5905 parameter to AC_DIAGNOSE.
5906 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
5907 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
5908 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
5909 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
5910 with AU::AC_OUTPUT.
5911 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
5912 in AC_OUTPUT doesn't double-quote it either.
5913 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
5914 parameters.
5916 2005-07-10 Stepan Kasal <kasal@ucw.cz>
5918 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
5919 versions of Portland Group compiler produce single- and double-quoted
5920 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
5921 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
5923 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
5925 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5926 This is a corrected version of yesterday's patch.
5928 2005-07-07 Stepan Kasal <kasal@ucw.cz>
5930 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
5931 path, too; insert a "===" to emphasize the line.
5933 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
5934 ac_cv_build_alias to ac_build_alias.
5935 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
5937 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
5938 change eliminates it. Problem reported by Alexandre Duret-Lutz.
5939 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
5940 (AC_ARG_VAR): ... here.
5941 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
5942 target_alias.
5944 Keep a list of all precious variables and process them with one simple
5945 for loop, instead of expanding all commands, or, OTOH, complicated
5946 processing of output of "set".
5947 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
5948 variable names in new macro...
5949 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
5950 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
5951 a loop to assign all ac_env_* and ac_cv_env_* variables.
5952 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
5953 to INIT_PREPARE.
5954 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
5955 its value to shell variable ac_precious_vars and call
5956 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
5957 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call

5981 2005-07-05 Stepan Kasal <kasal@ucw.cz>
5983 Fix my changes from 2005-07-01; reported by Noah Misch.

5994 versions of autoconf.
5996 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
5998 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

6003 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
6004 sed substitution command, so that we allow | in program prefixes

6008 configure_input, top_builddir, srcdir, etc.
6009 * lib/autotest/general.m4 (AT_INIT): Likewise, for
6010 PATH_SEPARATOR in AUTOTEST_PATH.
6012 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

6045 Likewise for --header; moreover, recognize --he and --h as shortcuts
6046 for --help in that case.
6048 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
6049 matches the order of execution. No code changed.

6071 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
6072 (AC_SUBST): Call it.
6073 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
6074 the directory specific variables; but don't call it for configure_input.
6076 2005-06-28 Derek Price <derek@ximbiot.com>
6078 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
6079 addition.
6081 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
6083 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
6084 directory have inherent problems with special characters like spaces,
6085 due to limitations in Make syntax. Problem reported by Alexandre
6086 Duret-Lutz.
6087 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

6103 because we really don't support spaces and suchlike in dir names.
6104 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
6105 Don't worry about backslashes in srcdir; it can't happen now.

6132 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
6133 b, t, r, w commands require single space, while : cannot have any.
6134 (Special Shell Variables): Fix sed code this in the example.
6135 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
6136 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
6138 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
6139 expand to the empty list. Don't use two pairs of m4_changequote,
6140 it's not necessary.
6142 2005-06-20 Derek Price <derek@ximbiot.com>
6144 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.

6148 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
6149 * doc/autoconf.texi:
6150 Don't mention Solaris versions so much, if a
6151 problem is common to all extant versions of Solaris. Say "SunOS
6152 4" instead of "SunOS" for SunOS 4.
6153 (awk): Mention more of the limitations of traditional Awk.
6154 (cat): Don't talk about cat -v.
6156 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

6161 to be compatible with glibc strverscmp.
6162 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
6164 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
6165 on Mac OS X 10.4 reported by Peter O'Gorman in:

6167 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
6168 Use shell builtins rather than 'expr', to work around expr bug.
6170 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
6172 * doc/autoconf.texi: "filesystem" -> "file system".
6173 "behaviour" -> "behavior".

6176 as per POSIX.
6177 * lib/m4sugar/m4sh.m4: Likewise.
6178 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem

6181 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
6182 (.x.1): Ignore the time stamp in the .TH line when deciding whether

6187 quotes and backslashes. Patch from Derek Price.

6192 AS_TR_SH.
6194 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
6196 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
6197 -u, since it outputs chatter if the input files are the same.
6198 Problem reported by Ralf Menzel.
6200 2005-06-08 Derek Price <derek@ximbiot.com>
6202 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
6203 renaming them since they are about to be redefined anyhow.
6205 2005-06-08 Derek Price <derek@ximbiot.com>
6207 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
6208 redefined M4 macros to this node. Document m4_include & m4_sinclude.
6209 Move m4_undefine to alphabetical order.
6211 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
6213 * README: Recommend GNU M4 1.4.3 or later.
6214 * doc/autoconf.texi (Introduction): Likewise.
6215 Reword to avoid some formatting glitches.
6216 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
6217 Clarify explanation of HP compiler bug.
6218 Redo example output tp match current CVS snapshot.
6219 Use @example.org in email addresses when the examples
6220 might get inadvertently cut-and-pasted into user code.
6221 Remove example of autom4te usage that doesn't seem to work now.
6222 Use modern AC_INIT (except when the example is meant to be
6223 shown with Autoconf 2.13).
6224 Update ksh info for Solaris 9 and later.
6225 KB -> kB.
6226 Modernize description of Automake versions a bit.
6227 Don't claim a future version of Autoconf is near.
6228 * doc/install.texi: Reword to avoid some formatting glitches.
6230 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6233 follows its own advice about quoting better.
6234 Reword to avoid some formatting glitches.
6235 * doc/installt.exi: Reword to avoid some formatting glitches.
6237 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
6238 Tru64 ksh pattern matching bug. Reported against Libtool by
6239 Albert Chin <libtool@mlists.thewrittenword.com> and
6240 Nicolas Joly <njoly@pasteur.fr>.
6242 2005-06-06 Stepan Kasal <kasal@ucw.cz>
6244 m4_cdr of one-member list was [[]] (one-member list containing an
6245 empty string) instead of [] (an empty list. Callers were skewed to
6246 match this misbehaviour. As a consequence of this:
6247 - m4_foreach([x], [], [foo]) expanded to `foo', while
6248 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
6249 This bug has been fixed:
6251 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
6252 expand to an empty string; print error msg if called without
6253 an argument list.
6254 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
6255 misbehaviour; handle [] and [[]] correctly.

6263 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
6265 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
6266 swallow records with more than 99 fields.
6267 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
6268 parse the long line.
6270 2005-06-04 Stepan Kasal <kasal@ucw.cz>
6272 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
6273 swallow literals longer than 399. Reported by Ralf Wildenhues.

6279 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
6280 to gfortran, and make these the first two compiler names
6281 checked (following the general autoconf preference for gcc).

6285 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
6286 (DISTCLEANFILES): Remove $(check_SCRIPTS).
6287 (testsuite): Make sure autotest.m4f is up-to-date before using it.

6291 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
6292 expression of unbounded size when processing the --list
6293 option. This runs afoul of a limit of 399 bytes per regular
6294 expression on AIX. Problem reported by Ralf Wildenhues.

6303 Reword description of line replacement.
6305 2005-05-31 Dan Manthey <dan_manthey@partech.com>
6307 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
6308 now contain newlines, and substituted files must be referenced on
6309 a line alone; the sed scripts to substitute them are now very
6310 different.
6311 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
6312 commands can be put in a sed script portably.
6313 * doc/autoconf.texi (Setting Output Variables): Document above
6314 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple

6325 * tests/local.at: Don't attempt to check for negated character
6326 classes in shell scripts. The test was too brittle.
6328 2005-05-25 Stepan Kasal <kasal@ucw.cz>
6330 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
6331 * doc/autoconf.texi (Limitations of Builtins): Document this
6332 limitation.
6334 2005-05-24 Stepan Kasal <kasal@ucw.cz>

6344 messages when ac_unique_file is not found.
6345 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
6346 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
6347 commands, for consistency with AC_MSG_ERROR and such.

6362 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
6363 (ac_top_builddir): ... this ...
6364 (ac_top_build_prefix): ... to this; the old name is also kept, for
6365 backward compatibility.
6366 (ac_top_builddir_sub): New variable, without the trailing slash,
6367 always nonempty.
6368 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

6382 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
6383 argument to m4_foreach. I guess it was necessary in the past,
6384 but I think it's a no-op now.
6386 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6388 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
6389 ``cat <<_ACEOF'' commands to one.
6390 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
6391 * lib/autoconf/status.m4: On various places, use expr instead of
6392 ``echo|sed.''
6393 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
6394 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.

6396 a range.
6397 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
6398 the wrong patterns between ``case'' and ``esac.'' The previous
6399 code had false positives.

6449 check.
6450 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
6451 enough arguments, similarly as in m4_bpatsubsts.
6453 2005-05-12 Stepan Kasal <kasal@ucw.cz>
6455 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

6460 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
6461 for absolute directory names in one loop.
6462 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
6463 abbreviations of --version and --debug.
6465 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
6467 * doc/autoconf.texi (Autoconf Language): Be more precise about
6468 quoting rules. Problems noted by Stepan Kasal.
6469 Also, throughout this document, be more careful about white space.
6470 "blank", "white space", and "space" all have different meanings
6471 and we should be careful to say what we mean.
6473 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
6475 Fix C++ related problems reported by Werner Lemberg.
6476 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
6477 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
6478 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
6479 avoid problems with C++ and throw.
6480 * tests/compile.at: .cpp, not .cc.
6482 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
6484 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6486 * doc/autoconf.texi (Generic Functions): Typos.
6488 2005-05-02 Gary V. Vaughan <gary@gnu.org>
6490 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
6491 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
6492 set by latest automake.
6494 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
6496 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
6497 outputs 0 on GNU/Linux these days.
6499 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
6501 * doc/autoconf.texi (Autoconf Language): Add more description
6502 about quoting heuristics.
6503 (Limitations of Builtins): Describe "set -" problems.
6505 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6507 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
6508 not newline.
6510 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
6511 by AC_DEFINE; it was a mistake.
6512 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
6514 2005-04-25 Stepan Kasal <kasal@ucw.cz>
6516 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
6518 2005-04-22 Stepan Kasal <kasal@ucw.cz>
6520 * doc/autoconf.texi (External Software): Quadrigraphs are not
6521 processed correctly in AS_HELP_STRING; avoid this in the examples.
6522 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
6523 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
6524 comment and reduce m4_default([foo], []) to [foo].
6525 (m4_strip): Update the explanation.
6527 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
6529 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
6530 Remove core.conftest.* too; it's generated by Tru64 5.1.
6531 Problem reported by Jennis Pruett.
6532 * lib/autoconf/functions.m4
6533 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
6534 Don't bother to remove core files; AC_RUN_IFELSE should do that
6535 for you.
6537 2005-04-19 Stepan Kasal <kasal@ucw.cz>
6539 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
6541 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>

6549 the comment.
6551 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
6553 * doc/autoconf.texi (External Software, Package Options): Add
6554 examples showing how to implement --with-* and --enable-* options.
6556 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
6558 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
6559 as well as configure.in. Problem reported by Gregorio Guidi.
6561 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
6563 * doc/autoconf.texi (Particular Functions): Use gnulib's current
6564 pattern for alloca snippet.
6566 2005-04-04 Stepan Kasal <kasal@ucw.cz>
6568 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

6574 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
6576 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
6577 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
6579 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6581 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
6582 Merge `-z option' as well for the benefit of Solaris link flags. Pass
6583 whole-archive (-zallextract, -zdefaultextract) options in the hope of
6584 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
6585 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
6587 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
6589 * NEWS: The configure command now warns you if you attempt to use
6590 a directory whose name contains a special character like space,
6591 newline, or "\".
6592 * doc/autoconf.texi (Installation Directory Variables): Allow
6593 "," in file names. Do not use \@; it's not a portable regexp.
6594 * bin/Makefile.am (edit): Likewise.
6595 * lib/Makefile.am (edit): Likewise.
6596 * tests/Makefile.am (edit): Likewise.
6597 * tests/semantics.at: Likewise.
6598 * tests/torture.at: Likewise.
6599 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
6600 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
6601 * doc/autoconf.texi (File System Conventions): Warn about
6602 unportable file names.
6603 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
6604 (AC_INIT): Use it.
6605 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
6606 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
6607 ac_pwd, and quote srcdir.
6608 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
6610 * doc/autoconf.texi: Fix some systematic formatting problems.
6611 ".)" needs a following @: if not at the end of a sentence, and
6612 similarly for "!)". "etc." should be preceded by a comma.
6613 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
6615 2005-03-22 Bruno Haible <bruno@clisp.org>
6617 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
6618 argument is often called 'build-aux'.
6620 2005-03-07 Stepan Kasal <kasal@ucw.cz>
6622 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
6623 macro AC_TRY_LINK is obsolete.
6624 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
6625 `AC_CONFIG_FILES'.
6627 2005-02-24 Stepan Kasal <kasal@ucw.cz>
6629 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
6630 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
6631 from a Common Lisp's `cl'.
6632 (AC_PROG_CXX): Behave according to the documentation: don't
6633 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
6634 make the variable CCC precious; use `cl.exe', not `cl'.
6636 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6637 Alexandre Duret-Lutz <adl@gnu.org>
6639 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
6640 /dev/null, as "configure" shouldn't read stdin, and this insulates
6641 us from problems (e.g., when testing for "cl"). Also, do this
6642 redirection before invoking "hostname" or "uname", and keep the
6643 original input stream available via...
6644 (AS_ORIGINAL_STDIN_FD): ... this new macro.
6645 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
6646 bother with "</dev/null" since it's now done at the top of
6647 'configure'.
6648 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
6649 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6650 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6651 * doc/autoconf.texi (File Descriptor Macros): New section.
6652 (Printing Messages): Mention it.
6653 * tests/base.at (Input/Output): New test.
6655 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6657 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
6658 newline if neither \c nor -n work, as that would output two
6659 newlines. Prefer -n to \c. Reported by Stepan Kasal.
6661 2005-02-12 Stepan Kasal <kasal@ucw.cz>
6663 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
6664 This causes that any required macros inside will get before the if.
6665 * doc/autoconf.texi (autom4te.cache): A typo.
6667 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
6669 Undo previous change, except keep the change to
6670 lib/autoconf/programs.m4 that replaced grep with shell
6671 pattern-matching. This is because net-snmp configure reads stdin.
6672 Reported by Noah Misch.
6674 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
6676 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
6677 from /dev/null, as "configure" shouldn't read stdin, and this
6678 insulates us from problems (e.g., when testing for "cl").
6679 Suggested by Alexandre Duret-Lutz. Also, do this redirection
6680 before invoking "hostname" or "uname".
6681 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6682 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
6683 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
6684 "</dev/null" since it's now done at the top of 'configure'.
6685 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6686 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6687 Also, replace grep with shell pattern-matching, to save a process.
6689 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
6691 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6692 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
6693 avoid thinking that Allegro Common Lisp's "cl" command is a C++
6694 compiler.
6696 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
6698 * doc/autoconf.texi (Limitations of Usual Tools): Document that
6699 grep -q isn't portable. Improve grep -s explanation.
6700 Problem reported by Dan Manthey.
6702 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
6704 * doc/autoconf.texi (Special Shell Variables): Clarify
6705 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
6707 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
6709 * doc/autoconf.texi: Use @acronym for DJGPP.
6710 Fix some @code's that should have been @env's, and vice versa.
6711 Sort environment variable names.
6712 Mention that shells no longer inherit IFS.
6713 Don't recommend PATH_SEPARATOR=';' so strongly.
6714 Mention that $RANDOM might expand to the empty string.
6715 "symlink" and "soft link" -> "symbolic link".
6716 Improve mktemp description (reported by Bruno Haible).
6718 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
6720 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
6721 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
6722 Likewise.
6723 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
6724 Likewise.
6726 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
6728 * NEWS: Mention AT_COPYRIGHT.
6730 * tests/local.at (AT_CMP): Use diff directly on input files rather
6731 than copying them.
6733 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
6734 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
6736 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6737 and Paul Eggert <eggert@cs.ucla.edu>
6739 * tests/autotest.at (Empty test suite): New test.
6740 * tests/torture.at (Substitute and define special characters)
6741 (Substitute a 2000-byte string, Define to a 2000-byte string)
6742 (Substitute a newline, Define a newline): New tests.
6744 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6746 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
6747 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
6748 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
6749 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
6750 (Standard regular expressions): New test.
6751 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
6752 excess test name quoting.
6753 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
6754 CPPFLAGS to `configure' instead of setting it in `configure'.
6756 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
6757 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
6758 on some platforms.
6760 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
6761 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
6763 * tests/local.at (AT_CMP): New macro.
6764 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
6765 (AC_SAVE_STATE): Move environment grep...
6766 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
6767 (AT_CONFIG_CMP): New macro.
6768 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
6769 * tests/c.at (Extensions): Do not exit early.
6770 * tests/atlocal.in: Inherit $GREP.
6772 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
6773 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
6775 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
6776 (AC_COPYRIGHT): Factor header comment portion out and move into...
6777 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
6778 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
6779 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
6780 --version output.
6781 * tests/local.at: Add Autoconf test suite copyright notice.
6782 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
6784 2005-02-04 Bruno Haible <bruno@clisp.org>
6785 and Paul Eggert <eggert@cs.ucla.edu>
6787 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
6789 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
6791 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
6792 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
6794 Try not to generated lines of unlimited length, as POSIX places a
6795 2047-byte limit on line length of portable text files.
6796 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
6797 Use newline as a separator, not space.
6798 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
6799 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
6800 space.
6802 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6804 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
6805 as_func_*. Add test to check whether positional parameters
6806 are restored after function return.
6808 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
6810 * doc/autoconf.texi (Special Shell Variables): Mention _,
6811 BIN_SH, DUALCASE. Say that variables other than "status" are safe
6812 if they contain a lower-case letter. The DUALCASE problem was
6813 reported by Ralf Wildenhues.
6815 * bin/autoconf.as: Don't exit with status 0 after write failure
6816 with --help or --version.
6817 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
6818 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
6820 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6822 * doc/autoconf.texi (Limitations of Usual Tools):
6823 Unicos 9 sed limitations.
6824 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
6825 to get the option-enhanced interface on older Crays. Try ftn for
6826 Fortran 95 (newer Crays).
6828 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
6830 * man/Makefile.am (.x.1): Go back to the simple solution, but take
6831 care to echo the commands, so the user knows what's going on.
6832 Modified from a suggestion by Stepan Kasal.
6834 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
6835 with a cross reference. Derived from a suggestion by Bruce Korb.
6837 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
6839 * doc/autoconf.texi (config.status Invocation): Warn about
6840 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
6841 * doc/install.texi (Defining Variables): Likewise.
6842 Based on a proposed patch by Ralf Wildenhues.
6844 * man/Makefile.am (.x.1): Make sure the required generated files
6845 are up to date. Problem and original solution proposed by Stepan Kasal.
6846 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
6847 implicit-man-prerequisites): New rules, used by the above.
6849 * doc/make-stds.texi, doc/standards.texi: Sync from gnulib.

6855 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
6856 Update the long comment explaining it.
6858 m4_require no longer writes an ``is required by'' line to the
6859 execution stack. It contains only one bit of non-redundant
6860 information: that the macro was required, not called. And even
6861 this bit is useless in most situations: have you ever met a macro
6862 which both calls and requires the same macro?
6864 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
6865 (_m4_defun_pro_outer): ... only via this macro, for the outermost
6866 macro.
6867 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
6868 (m4_expansion_stack_pop): Remove the misplaced comment.
6869 (m4_require): Don't put the ``is required by'' line to the
6870 execution stack; slightly improve the out-of-a-defun error message.
6871 (_m4_divert_grow): New macro, counter for the temporary diversions.
6872 (_m4_require_call): Use it.
6873 * tests/m4sugar.at (m4_require): Expect output without the
6874 ``is required by'' messages.
6876 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
6878 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
6879 rather than x for expr.
6881 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
6882 this is safe.
6883 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
6884 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

6897 support.
6898 * bin/autoheader.in: Pass $force to update_file so that
6899 config.h.in is always recreated when --force.

6910 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
6912 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
6913 Warn about newline stripping in `` and $(). Update Solaris
6914 version to 9.

6918 stripping.
6920 2005-01-19 Stepan Kasal <kasal@ucw.cz>

6940 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
6942 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
6944 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

6968 otherwise.
6969 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
6970 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
6971 stored in _m4_divert_diversion or _m4_divert_dump.
6972 (m4_divert_pop): When the parameter is given, compare the symbolic
6973 name with the last diversion pushed on the stack. Previously, the
6974 current diversion was compared with the numeric value of the
6975 diversion given as the parameter.
6976 (m4_require): If the macro hasn't been expanded yet, call ...
6977 (_m4_require_call): this new macro.

7010 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

7012 not essential. Reported by Magnus Therning.
7013 * tests/torture.at (autoreconf.): New banner.
7014 (autoreconf and non-AC configure): Rename to `Non-Autoconf

7063 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
7064 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

7191 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

7256 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>

7259 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
7260 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
7261 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.

7265 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

7277 out the common code to ...
7278 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
7279 value of the #define--default to 1, iff the macro was called
7280 with exactly one parameter.
7282 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
7284 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
7285 "char c = '\200';" rather than "char c = 0x80;" as the
7286 latter doesn't conform to the strict C standard due to
7287 overflow on signed char hosts.
7289 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
7290 to -qlanglvl=ansi. We don't want to disable extensions.
7292 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
7294 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

7309 * doc/autoconf.texi (Libtool): Libtool can be used without
7310 Automake (not without Autoconf).
7311 (Introduction): Mention lists.gnu.org.
7312 * BUGS: Don't mention bugs.gnu.org.
7313 Remove mention of ancient libtool compatibility problem.
7314 * NEWS: Mention that bugs.gnu.org is kaput.
7315 * README: Likewise. Mention where mailing list archives can be found.
7317 2004-11-28 Stepan Kasal <kasal@ucw.cz>

7323 * doc/autoconf.texi (Pretty Help Strings): Go back to
7324 single-quoting assignments to cache variables.
7326 2004-11-23 Stepan Kasal <kasal@ucw.cz>
7328 * doc/autoconf.texi (Pretty Help Strings): Fix quoting issues

7344 (Quotation Rule Of Thumb): Likewise.
7345 (Pretty Help Strings): Likewise; remove the wrong comment;
7346 simplify the examples and improve their quoting.
7348 2004-11-13 Stepan Kasal <kasal@ucw.cz>
7350 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
7351 the $1_found variable, don't test whether the file is executable;
7352 Both things are checked ...
7353 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
7354 the former ``test -f''.
7355 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
7357 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>
7359 * doc/autoconf.texi (Limitations of Usual Tools): Avoid cp -r;
7360 use cp -R instead.
7362 2004-11-10 Derek R. Price <derek@ximbiot.com>
7364 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
7365 limitations. Reorder paragraphs for clarity.
7367 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
7369 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
7370 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
7371 variants", "Unix", and some related minor wording fixups.
7373 (Shellology, Special Shell Variables): Document that the Zsh
7374 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

7386 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
7388 * doc/autoconf.texi (auindex): New macro.
7389 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
7390 Problem reported by Stepan Kasal.
7392 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
7394 Fix problems reported by Andreas Buening in:
7395 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
7396 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
7397 in test makefile.
7398 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
7399 readable; it's not true in OS/2-emx.
7401 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
7403 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
7404 "/usr/include", clear ac_x_includes instead of leaving it as "no"
7405 (trivial change). Problem and patch reported by Andrew Church in:
7406 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
7408 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
7410 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
7411 three args in examples. Problem reported by Frederik Fouvry in:
7412 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
7413 Also, fix some minor spacing and punctuation bugs.
7415 2004-09-02 Akim Demaille <akim@epita.fr>
7417 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
7418 "case" to restore ordering.
7419 Reported by Stepan Kasal.
7421 2004-08-26 Akim Demaille <akim@epita.fr>
7423 * doc/autoconf.texi: Minor typos and stylos.
7425 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
7427 * configure.ac (AC_INIT): Bump to 2.59c.
7429 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
7431 Version 2.59b.
7433 * README: Add advice about m4 1.4.2.
7435 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
7436 texinfo.tex for now (done by hand now).
7437 * Makefile.maint (wget_files, cvs_files):
7438 Remove ansi2knr.c; nobody uses it.
7439 (ansi2knr.c-url_prefix): Remove.
7440 (cvs-update): Fix test for failure. I don't know why it ever
7441 worked...
7443 * doc/autoconf.texi: Update URLs, some of which went stale.
7444 Use @uref rather than @href.
7446 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
7447 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
7449 * config/config.guess, config/config.sub, config/elisp-comp,
7450 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
7451 doc/fdl.texi, doc/standards.texi: Sync with master copy.
7453 * NEWS, TODO, configure.ac, bin/autoscan.in,
7454 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
7455 doc/install.texi, lib/Autom4te/Configure_ac.pm,

7459 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
7460 tests/tools.at, tests/torture.at:
7461 Use "file name" rather than "filename" or "path",
7462 to be consistent with the terminology of the GNU coding standards.
7464 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
7466 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
7467 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
7468 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
7469 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
7471 More fixes to support spaces in the name of the build directory.
7472 This isn't a complete fix but it's an improvement.
7474 * bin/autoconf.as (autom4te_options): New var.
7475 Use it instead of appending to AUTOM4TE, so that we can allow
7476 spaces in the build directory's absolute name.
7477 * bin/autoheader.in ($autoconf): Allow spaces in file names.
7478 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
7479 AT_CHECK_NOESCAPE): Likewise.
7480 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
7481 main program): Likewise.
7483 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
7485 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

7489 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
7491 * doc/autoconf.texi (Function Portability): Document isinf and
7492 and isnan. From a suggestion by Kevin Ryde.
7494 * lib/Autom4te/General.pm (END): Return correct exit status even
7495 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
7497 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
7499 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
7500 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
7501 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
7503 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
7505 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
7506 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
7507 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
7508 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
7509 * lib/autom4te.in (Automake-preselections): Preselect
7510 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
7512 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
7514 * lib/autom4te.in (Automake-preselections): Preselect
7515 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
7516 trace them.
7518 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
7520 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
7521 Tru64.
7522 * doc/autoconf.texi (Shellology): Mention BIN_SH.
7523 Document problem with "`""`" in pdksh POSIX mode.
7525 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
7527 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
7528 with pdksh, too. Problem reported by Patrick Welche via
7529 Gary V. Vaughan.
7530 * doc/autoconf.texi (Shellology): Note that set -o posix is
7531 useful for pkdsh, too.
7533 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
7535 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
7536 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
7537 Don't fail if ENV or BASH_ENV is readonly.
7538 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
7539 etc. are read only. Problem reported by Ludovic Courtes.
7541 2004-06-23 Noah Misch <noah@cs.caltech.edu>
7543 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
7544 zsh, disable GLOB_SUBST to avoid backslash handling problems.
7545 (trivial change)
7547 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
7549 * doc/autoconf.texi (File System Conventions): Warn about
7550 names like "aux". Problem reported by Eric Blake.
7552 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
7553 by zero instead of array size, so that we can use any arithmetic
7554 constant expression (instead of requiring an integer constant
7555 expression). This allows us to test expressions like DBL_MAX <
7556 LDBL_MAX, which didn't conform to the C standard using the old
7557 method.
7558 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
7559 now that we can do floating-point tests at compile time.
7561 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
7563 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
7564 and LDBL_EPSILON, as the resulting expression isn't an
7565 integer constant expression and violates the C standard.
7566 Problem reported by Nelson H. F. Beebe. Also, check
7567 for "L" suffix, and check that long double doesn't have
7568 worse range or precision than double, that mixed-mode
7569 arithmetic doesn't generate a diagnostic, that double
7570 constants fit in long double.
7572 2004-06-03 Kevin Ryde <user42@zip.com.au>
7574 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
7575 malloc(0) and realloc(NULL,size).
7577 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
7578 Bob Proulx.
7580 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
7582 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
7583 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
7584 by Jim Meyering.
7586 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
7588 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
7589 can be rewritten using if-then-else. Suggested by Bruno Haible.
7591 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
7593 * doc/autoconf.texi (testsuite Scripts): Fix typo.
7594 Problem reported by Stepan Kasal.
7596 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
7598 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
7599 change). Patch reported by Ralf Wildenhues in
7600 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
7602 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
7603 function F exists if the compiler and linker let you compile an
7604 expression like (F != 0). Recent versions of GCC optimize away
7605 the reference to F in that case, since every function address must
7606 be nonzero, so the link succeeds even if F does not exist.
7607 Problem reported by Manu in
7608 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
7610 * doc/autoconf.texi (Systemology): Standardize on the spelling of
7611 "Unix". Many uses changed.
7612 (Limitations of Builtins): Explain better why the ! command isn't
7613 portable.
7615 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
7617 * lib/autom4te.in (Automake-preselections): Preselect
7618 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
7620 2004-05-19 Kevin Ryde <user42@zip.com.au>
7622 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
7623 referencing AC_FUNC_STRERROR_R.
7625 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
7626 note pessimistic assumption when cross compiling.
7628 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
7630 * doc/autoconf.texi (Limitations of Make): Note that BSD make
7631 (until 2004) invoked subcommands with sh -e, contra POSIX.
7632 Reported by Kevin Ryde.
7634 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
7636 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
7637 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
7638 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
7639 `test -f " /usr/bin/grep"', which _always_ failed.
7640 (AC_PROG_SED): Ditto bogus PATH fix.
7641 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
7642 requires that grep correctly supports _multiple_ `-e' options, rather
7643 than stating only that grep should accept `-e'.
7645 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
7647 Port to C99, which requires that 'exit' be declared.
7649 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
7650 to ensure that stdlib.h is included.
7651 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
7652 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
7653 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
7654 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
7655 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
7656 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
7657 when using 'exit' in a test; C99 requires that 'exit' be declared.
7659 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
7661 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
7662 now prefers 'grep' implementations that accept -e.
7663 (Limitations of Usual Tools): Describe problems of traditional
7664 egrep and fgrep with long input lines, and of traditional grep
7665 with -e.
7666 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
7667 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
7668 All callers changed. Append /usr/xpg4/bin to the PATH, for
7669 Solaris.
7670 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
7671 the user with complaints about multiple -e options.
7672 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
7673 Define it with AC_PROG_GREP.
7674 * configure.ac (AC_PROG_GREP): Add.
7675 * lib/freeze.mk (GREP): New macro.
7677 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
7679 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
7680 a possible candidate only after all others fail, rather than
7681 consulting it first. This improves backward compatibility by
7682 better reflecting the way shell selection occurred in previous
7683 versions of Autoconf, and should help to avoid triggering latent
7684 problems in other packages, such as the one in Automake where zsh
7685 is not handled robustly:
7686 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
7687 Although it is not Autoconf's responsibility to work around
7688 problems in Automake, it nevertheless makes sense to avoid
7689 introducing unnecessary incompatibilites.
7691 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
7692 Gary V. Vaughan <gary@gnu.org>
7694 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
7695 how deeply nested we are when a suitable tool is found, set the
7696 ac_path_TOOL_found flag.
7697 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
7698 nested we are in this macro. Break out of all 3 nested loops if
7699 ac_path_TOOL_found is set.
7701 2004-04-21 Gary V. Vaughan <gary@gnu.org>
7703 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
7704 of the _AS_PATH_WALK loop too if GNU flavor is found.
7706 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
7708 * doc/autoconf.texi (Limitations of Make): Update documentation
7709 for `$<'. New entry `Long lines', based on a report from Simon
7710 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
7711 paragraph about DJGPP, based on a mail from Richard Dawe.
7713 2004-04-20 Paul Eggert <eggert@twinsun.com>
7715 * tests/c.at (C keywords): Don't assume that GCC supports
7716 "restrict" and "inline", as sufficiently-old GCC versions do not
7717 (also, GCC configured to be in pedantic C89 mode does not).
7718 Problem reported by Sumit Pandya in:
7719 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
7721 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
7722 consider -g to work if it generates warnings when plain compiles
7723 don't. Problem reported by Braden McDaniel in:
7724 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
7726 * doc/autoconf.texi (Slashes): New section, to document a problem
7727 reported by Jim Meyering in:
7728 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
7730 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
7731 linker output files before linking, to work around IRIX 6 linker bug.
7732 Problem reported by Rainer Orth in:
7733 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
7735 2004-04-20 Gary V. Vaughan <gary@gnu.org>
7737 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
7738 best tool so far counter rely on the tool path variable name to
7739 avoid checks for one tool being affected by the results of running
7740 the length check on a previous tool.
7742 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
7743 match expression argument, as different greps have different
7744 regular expression flavours.
7745 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
7746 literals.
7747 (AC_PROG_EGREP): Pass 'EGREP$'.
7748 (AC_PROG_GREP): Pass 'GREP$'.
7750 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
7752 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
7753 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
7755 2004-03-29 Paul Eggert <eggert@twinsun.com>
7757 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
7758 Types, Specific Compiler Characteristics, System Services,
7759 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
7760 etc. consistently instead of 'long', 'short', 'unsigned' etc.

7837 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
7838 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than

7865 2004-02-18 Paul Eggert <eggert@twinsun.com>
7867 Fix a dependencies problem, stemming from a Autoconf 2.59 build
7868 problem on QNX reported by Stephen Rasku in

7882 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
7883 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
7884 Darwin uses -lcrt2.o and there's little point to cataloging all
7885 the system variants. Partial fix reported by Andreas Waechter in:
7886 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

7917 (_AS_SHELL_FN_SPY): New macro.
7918 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New

7930 use AS_INIT_WITH_SHELL_FN.
7931 * bin/autoconf.in, tests/wrapper.in: Regenerated.
7933 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

7961 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

7963 the 2003-05-22 change, which removed the older years from the list.
7964 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
7966 2004-01-27 Gary V. Vaughan <gary@gnu.org>

8006 sources.
8008 2004-01-26 Paul Eggert <eggert@twinsun.com>
8010 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
8011 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
8012 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
8013 not <inttypes.h>. Problem reported by Tim Mooney in
8014 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
8015 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
8016 Likewise.
8018 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
8019 otherwise "make check" fails because it forbids cmp (I guess
8020 because cmp treats files as binary on DOS-like systems).
8022 * tests/mktests.sh: Update copyright date to 2004, since some tests
8023 have changed in 2004.
8025 2004-01-23 Gary V. Vaughan <gary@gnu.org>

8028 non-truncating sed or gsed program in PATH.

8031 * NEWS: Updated.
8033 2004-01-15 Paul Eggert <eggert@twinsun.com>
8035 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
8036 -std1 disables some useful extensions on Tru64. Problem reported
8037 by N. Lichtmaier in
8038 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
8040 2004-01-14 Paul Eggert <eggert@twinsun.com>
8042 * doc/autoconf.texi (Programming in M4sh): Document that
8043 AS_MKDIR_P succeeds if the destination is a symbolic link
8044 to an existing directory.
8045 (Limitations of Usual Tools): Note that mkdir -p might not
8046 succeed on symlinks to directories.
8048 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
8050 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
8051 * bin/autoheader.in: Grammar fix in message.

8057 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
8058 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
8060 2004-01-10 Jim Meyering <jim@meyering.net>
8062 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
8064 2004-01-09 Paul Eggert <eggert@twinsun.com>
8066 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
8067 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
8068 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
8069 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
8070 AC_COMPILE_IFELSE, since we now assume our caller invokes
8071 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
8072 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
8073 of AC_RUN_IFELSE; this avoids the warning mentioned above.
8074 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
8076 2004-01-07 Paul Eggert <eggert@twinsun.com>
8078 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
8079 `"'...'"`, as it's confusing (and I suspect it may not work on
8080 some platforms). The code was incorrect anyway, as it assumed
8081 that \$ evaluated to itself in that context. Reported by
8082 Alexandre Duret-Lutz.
8084 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
8086 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

8091 * doc/autoconf.texi (One Macro Call): Fix an incorrect
8092 example, and add more examples. Reported by Eric Sunshine.
8094 2004-01-05 Paul Eggert <eggert@twinsun.com>
8096 * doc/autoconf.texi (Limitations of Usual Tools):
8097 Remove warning against "rm -fr" introduced yesterday; it
8098 was a false alarm.
8100 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
8101 autoscan, autoupdate, ifnames): Don't use chmod -w.
8102 * lib/Makefile.am (autom4te.cfg): Likewise.
8103 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
8104 "chmod -w".

8114 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
8115 Use "rm -f" to remove conftest.sed, not plain "rm".
8116 Bug reported by David Relson in
8117 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
8119 * Makefile.am (autom4te-update):
8120 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
8121 * Makefile.maint (my-distcheck, do-po-update): Likewise.
8122 * doc/autoconf.texi (Guidelines): Likewise.

8132 Warn against "rm -fr".

8136 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
8137 -c -o might not work. From a suggestion by Kevin Ryde.
8138 (C Compiler, Generating Sources, Limitations
8139 of Usual Tools, Limitations of Make, Making testsuite Scripts):
8140 Don't put '-o' after non-options, as POSIX doesn't allow this.
8141 Mention that cc's name might be gcc or c89 or whatever.
8143 2004-01-04 Kevin Ryde <user42@zip.com.au>
8145 * doc/autoconf.texi: Add various further index entries.
8147 2003-12-29 Paul Eggert <eggert@twinsun.com>
8149 * bin/autoreconf.in (autoreconf_current_directory):
8150 Fix typo: mkdir without umask arg.
8152 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
8154 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
8155 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
8156 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
8157 explanation clearer.
8159 2003-12-24 Andreas Schwab <schwab@suse.de>
8161 * doc/autoconf.texi (Default Includes): Fix misspelling of

8167 * configure: Regenerate.
8168 * tests/atlocal.in: Store the result here.
8169 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
8170 tools.at, looking in atlocal's ac_cv_sh_n_works instead
8171 of explicitly testing.
8172 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
8173 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
8174 * tests/tools.at (Syntax of the shell scripts): Simplify
8175 using AT_CHECK_SHELL_SYNTAX.

8177 AT_CHECK_PERL_SYNTAX.
8179 2003-12-03 Paolo Bonzini <bonzini@gnu.org>

8190 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
8191 macros.
8192 (AS_SHELL_SANITIZE): Move reinvocation code from
8193 _AS_LINENO_WORKS, use it to find out if shell
8194 functions work.
8195 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
8196 does not work.
8197 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

8208 * config/announce-gen (&print_locations, &print_signatures)
8209 (&sizes): New.
8210 Use them.
8211 No longer rely on Gnus to inline the list of signatures: compute
8212 them on the fly.
8214 2003-11-24 Akim Demaille <akim@epita.fr>
8216 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

8265 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

8285 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

8420 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
8421 cross test.
8423 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
8425 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
8426 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

8438 Problems reported by Eric Sunshine.
8440 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
8442 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
8443 -mGLOB_options_string stuff for Intel ifc, which can cause
8444 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

8467 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
8468 cache variable instead of $G77 to decide whether to include -O2,
8469 since $G77 is specific to Fortran 77.

8473 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

8478 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
8479 arguments so that it can be used with syntax identical to
8480 AC_PROG_F77, and so that we can more easily decide to
8481 remove/deprecate the DIALECT optional argument in the future if it
8482 proves troublesome.
8483 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
8484 non-freeform-supporting compilers. Document freeform flags.
8486 2003-10-03 Akim Demaille <akim@epita.fr>
8488 * configure.ac: Look for emacs, not macs.

8498 2003-10-03 Akim Demaille <akim@epita.fr>
8500 * configure.ac: Quotation and formatting changes.

8535 have been created when invoking the compiler.

8550 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
8551 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
8553 2003-09-26 Akim Demaille <akim@epita.fr>
8555 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
8556 directory for AC_CONFIG_COMMANDS' first argument exists.
8557 This makes valid the invocation of _AC_SRCPATH that follows.
8558 Reported by Eric Sunshine.
8559 * doc/autoconf.texi (Configuration Commands): Adjust.
8561 2003-09-26 Akim Demaille <akim@epita.fr>
8563 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
8564 Reported by Ralf Corsepius.

8568 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
8569 arguments.

8580 2003-09-26 Akim Demaille <akim@epita.fr>
8582 The test suite are sometimes assigning timings incorrectly.
8583 Reported by Henk Krus.
8584 Diagnosed by Nicolas Joly.
8586 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
8587 AT_help_all.
8588 Instead of making AT_help a sequence of assignments to grow
8589 $at_help_all, just make AT_help_all be the growing contents of
8590 $at_help_all, and make a single assignment in...
8591 (AT_INIT): here.
8592 (at_times_skip): Flip the meaning and rename as...
8593 (at_times_p): this.
8594 (AT_INIT): When summarizing the test that ran, remove
8595 $at_times_file after use, and check it is present before trying to
8596 use it.

8604 (ifnames): chmod -w.
8605 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
8606 executables, not bin/ executables! Otherwise all the magic needed
8607 to find non installed files is turned off. This caused a failure
8608 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
8609 as found in its environment (sent by tests/autoreconf): pointing
8610 to bin/autom4te that could not find its files.
8611 * tests/mktests.sh: Force the replacement of generated files, for
8612 the sake of "mv" program that are interactive when overwriting a
8613 -w file.

8624 Trivial change to support GCC's configuration procedure.
8625 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
8626 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
8627 about inconsistency if the preprocessor is set to give errors for
8628 any warning.

8652 2003-09-11 Akim Demaille <akim@epita.fr>
8654 * doc/autoconf.texi (Header Portability): linux/random.h.
8655 From Peter Hendrickson.
8657 2003-09-10 Akim Demaille <akim@epita.fr>
8659 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
8660 willing to edit the output files.
8662 2003-09-10 Akim Demaille <akim@epita.fr>
8664 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
8665 and AC_FC_FREEFORM.
8666 * tests/mktests.sh: Skip AC_FC_SRCEXT.
8667 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

8682 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
8683 Improve the accuracy of the wording about obsolescence.
8684 From a suggestion by Ian Lance Taylor in
8685 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
8687 2003-09-05 Paul Eggert <eggert@twinsun.com>
8689 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
8690 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
8692 2003-09-04 Akim Demaille <akim@epita.fr>
8694 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
8695 AC_FUNC_WAIT3.
8697 2003-09-04 Akim Demaille <akim@epita.fr>
8699 * bin/autom4te.in: Use &fatal where more appropriate than &error.
8700 (freeze): When exiting, use $exit_code.
8701 * lib/autoconf/fortran.m4: Comment changes.
8703 2003-09-04 Akim Demaille <akim@epita.fr>
8705 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
8707 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
8709 Add support for newer Fortran dialects. The F77 interface is
8710 unchanged, and continues to support Fortran 77. New FC macros
8711 correspond to all the old F77 macros, with output variables FC,
8712 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
8713 available dialect, but older dialects can be specified. There are
8714 new macros AC_FC_SRCEXT to set the source extension, and
8715 AC_FC_FREEFORM to accept free-form source files.
8717 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
8718 New macros.
8719 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
8720 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
8721 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
8722 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

8730 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
8731 AC_FC_SRCEXT, AC_FC_FREEFORM):
8732 New macros.
8733 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
8734 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
8735 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
8736 Rewrite in terms of the above.
8737 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
8738 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

8744 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
8745 Document problems with timestamp resolution that 'make', 'cp -p', and
8746 'touch -r' have.
8748 2003-08-27 Akim Demaille <akim@epita.fr>
8750 * tests/m4sugar.at (cross_warning): Make sure to enable the
8751 output, so that we can track spurious m4sugar output.
8752 * tests/local.at: Require 2.57.
8753 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
8754 are defaulted by AT_CHECK anyway.
8755 Use AT_CHECK_AUTOM4TE.
8756 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
8757 missing dnl.
8759 2003-08-27 Akim Demaille <akim@epita.fr>
8761 * bin/autoheader.in: Issue the "Using auxiliary..." message only
8762 when -Wobsolete is set.
8763 Set it on by default.
8764 Suggested by Klee Dienes.
8766 2003-08-27 Akim Demaille <akim@epita.fr>
8768 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More

8775 after AC_OUTPUT.
8777 2003-08-25 Akim Demaille <akim@epita.fr>
8779 * config/announce-gen, GNUmakefile, Makefile.maint: Update from

8801 * Makefile.maint (local-check): Rename as...
8802 (local-checks-available): this.
8803 (local-check): New.
8805 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
8806 * configure.ac: Require Automake 1.7.6.
8808 2003-08-22 Akim Demaille <akim@epita.fr>
8810 Output stack traces in warnings.
8812 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
8813 Replace the former...
8814 (m4_warn): Pass the call stack to _m4_warn.
8815 * bin/autom4te.in: Adjust to output the call stack.
8816 * tests/m4sugar.at (m4@&t@_warn): Adjust.
8818 2003-08-22 Akim Demaille <akim@epita.fr>
8820 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
8821 * bin/autom4te.in: Adjust.
8823 2003-08-21 Akim Demaille <akim@epita.fr>
8825 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
8826 (&verbose): Remove.
8827 (&getopt): Adjust the note and verb channels, depending upon
8828 --verbose.
8829 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
8830 * bin/autoupdate.in: Adjust.
8831 Use &verb, not &verbose.
8833 2003-08-21 Akim Demaille <akim@epita.fr>
8835 * bin/autoheader.in (&parse_args): Use &parse_warnings and
8836 &parse_WARNINGS.
8837 ($help): Use Autom4te::ChannelDefs::usage.
8838 * bin/autoscan.in: Use Autom4te::ChannelDefs.
8839 * lib/Autom4te/General.pm: Don't export error: you don't own it.
8841 2003-08-21 Akim Demaille <akim@epita.fr>
8843 First stab at preserving warnings between calls to autom4te,
8844 including when the cache is used.
8846 There are still several issues: (i) there are too many runs of m4
8847 (one for include, one for warnings, and some more), (ii) warnings
8848 spreading on several lines are not handled gracefully, (iii) the
8849 code meant to have the call stack display for errors does not work
8850 (its handling should move from m4 to autom4te).
8852 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
8853 Use them.
8854 (@preselect): Add m4_warn.
8855 ($exit_status): Remove, use $exit_code.
8856 ($help): Use Autom4te::ChannelDefs::usage.
8857 (&handle_m4): No longer define the m4_warnings.
8858 At each run, extract and report the warnings.
8859 Always cache the result, including if the exit status is on
8860 failure, since if nothing changes, we should result in the same
8861 failure, hence we can use the cache.
8862 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
8863 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
8864 Remove.
8865 (m4_warn): Redefine as a do-nothing: it is its invocation that
8866 matters, as warnings are now reported via traces.
8867 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
8868 the contents of m4_warn: make it _call_ m4_warn, so that tracing
8869 the latter reveals calls to the former.
8871 Adjust the tests.
8873 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
8875 2003-08-21 Akim Demaille <akim@epita.fr>
8877 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
8878 Use them.
8880 2003-08-21 Akim Demaille <akim@epita.fr>
8882 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
8883 forward order.
8884 * lib/Autom4te/ChannelDefs.pm: Doc typos.
8885 (&parse_warnings): Accept a list of warning requests.
8886 (&usage): Return a string, not a side effect.
8887 (cross): New warning category.
8889 2003-08-21 Akim Demaille <akim@epita.fr>
8891 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
8892 (&require_configure_ac): Accept an optional directory argument.
8893 ($configure_ac): Remove.
8894 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
8895 (&catfile): Remove.
8896 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
8897 * bin/autoscan.in: Adjust.
8899 2003-08-20 Akim Demaille <akim@epita.fr>
8901 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
8902 Reported by Alexandre Duret-Lutz.
8904 2003-08-20 Akim Demaille <akim@epita.fr>
8906 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
8907 * bin/autom4te: Adjust.
8908 In particular, be Autoconf tools are really silent when properly
8909 working, bind the verbosity of the 'note' channel to $verbose.
8910 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
8911 (&xsystem, &contents): Remove, since they are exported by...
8912 * lib/Autom4te/FileUtils.pm: this.
8913 More perldoc.
8914 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
8915 * lib/Autom4te/FileUtils.pm: here.
8917 2003-08-20 Akim Demaille <akim@epita.fr>
8919 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
8920 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
8921 from CVS Automake.
8923 2003-08-20 Akim Demaille <akim@epita.fr>
8925 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
8926 (autom4te-update): New.
8927 * Makefile.cfg (update): Bind autom4te-update.

8931 * lib/autotest/general.m4: Comment various HELP_* diversions.
8932 (PARSE_ARGS_BEGIN): New section for option parsing related

8943 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
8945 * lib/autom4te.in (Automake-preselections): Preselect
8946 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
8947 and m4_sinclude.
8949 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
8951 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...

8953 * doc/autoconf.texi (autom4te Invocation): Mention
8954 Autoconf-without-aclocal-m4.

8959 RUN-IF-PASS optional arguments.

8968 STDOUT & STDERR arguments.
8970 2003-08-14 Derek Price <derek@ximbiot.com>
8972 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
8973 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
8974 shorter column three. Add DESCRIPTION to log file content.
8976 2003-08-13 Derek Price <derek@ximbiot.com>
8978 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
8979 output.
8981 2003-08-12 Derek Price <derek@ximbiot.com>
8983 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
8984 (AT_CHECK_NOESCAPE): Move core functionality to...
8985 (_AT_CHECK): ...this new macro.
8987 2003-08-07 Derek Price <derek@ximbiot.com>
8989 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
8990 (AT_CHECK_NOESCAPE): ...to this new macro.
8992 2003-07-31 Paul Eggert <eggert@twinsun.com>
8994 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
8995 in Bash 2.01. Problem reported by Brian Gough in
8996 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
8998 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
9000 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
9001 -lcrt1.o, for OS X. (trivial change)
9003 2003-07-07 Paul Eggert <eggert@twinsun.com>
9005 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
9006 inside '#ifndef __cplusplus'. Problem reported by
9007 Bob Friesenhahn.
9009 2003-07-06 Bill Clarke <llib@computer.org>
9011 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
9012 'long', not 'int', for benefit of Sun's recent C++ compilers
9013 (trivial change). See:
9014 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
9015 (This really should be 'intptr_t', not 'long', but that would
9016 take more work.)
9018 2003-06-25 Akim Demaille <akim@epita.fr>
9020 * lib/Makefile.am (autom4te.cfg): Make it read only.
9021 Depend on Makefile since it contains substitutions.
9022 From Paolo Bonzini.
9023 * lib/autom4te.in (args): Add local.at? for Autotest args.
9024 This change was made on autom4te.cfg which is generated.
9025 Reported by Raja R. Harinath.
9027 2003-06-25 Akim Demaille <akim@epita.fr>
9029 * doc/autoconf.texi (Header Portability): sys/mount.h.
9030 From Gareth McCaughan.
9032 2003-06-23 Akim Demaille <akim@epita.fr>
9034 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
9035 not all of them. This fixes 1. the fact that when testing
9036 Autoconf there are many many config.log, 2. the incorrect use of
9037 top_srcdir to find config.log.
9038 Don't mix the detailed output of failed test with the summary of
9039 failures. Rather, append detailed log afterwards.
9041 2003-06-23 Akim Demaille <akim@epita.fr>
9043 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
9044 always run: output config.log on $at_group_log.
9046 2003-06-23 Akim Demaille <akim@epita.fr>
9048 * tests/torture.at (#define header templates): Don't use quotes in
9049 C++ comments as it puzzles Emacs' sh font-lock-mode.
9051 2003-06-23 Akim Demaille <akim@epita.fr>
9053 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
9054 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
9055 * tests/atspecific.m4: Rename as...

9057 * tests/suite.at: Move the globals into...
9058 * tests/local.at: here.
9059 * tests/Makefile.am: Adjust.
9060 * doc/autoconf.texi (testsuite Scripts): Adjust.
9062 2003-06-21 Kevin Ryde <user42@zip.com.au>
9064 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
9065 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
9066 ensuring we add -std1 for full-ANSI.
9068 * doc/autoconf.texi (hdrindex): New macro.
9069 Add index entries for portability of various standard header files.
9071 2003-06-20 Akim Demaille <akim@epita.fr>
9073 * configure.ac: Bump to 2.57b.
9075 2003-06-20 Akim Demaille <akim@epita.fr>
9077 Version 2.57a.
9079 2003-06-20 Akim Demaille <akim@epita.fr>
9081 * bin/autom4te.in: Don't rely on $HOME being defined.
9082 Reported by Marc Espie as PR/233.
9084 2003-06-20 Akim Demaille <akim@epita.fr>
9086 * lib/autotest/general.m4: Use at_times_file only if used.
9087 From Nicolas Joly.
9089 2003-06-20 Akim Demaille <akim@epita.fr>
9091 * config/config.guess, config/config.sub, config/elisp-comp,
9092 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
9093 Update from masters.
9095 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
9097 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
9098 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
9099 (TEST_SCRIPT): New diversion.
9100 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
9101 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
9102 (AT_INIT): Support for expected failures.
9104 2003-06-02 Akim Demaille <akim@epita.fr>
9106 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
9107 changes.
9108 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
9109 Autoconf nor Automake.
9110 (&contents): New, from Automake.
9111 PODify.
9113 2003-05-28 Paul Eggert <eggert@twinsun.com>
9115 * NEWS, doc/autoconf.texi (Particular Functions),
9116 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
9117 is the inverse of localtime.
9119 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
9121 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
9122 (handle_exec_errors): New function. Work around $! being
9123 altered by WEXITSTATUS.
9124 (xqx, xsystem): Use handle_exec_errors.
9126 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
9128 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
9129 Do not call `_exit()', simply modify `$?'.
9130 (xsystem): Reset $! before running system, and check it afterward.
9131 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
9132 63 for version mismatches.
9134 2003-05-23 Akim Demaille <akim@epita.fr>
9136 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
9137 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
9138 the middle of a line).
9139 * lib/m4sugar/m4sugar.m4: Likewise.
9140 Remove useless spaces in comments.
9142 2003-05-23 Akim Demaille <akim@epita.fr>
9144 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
9145 exit 63, so that we (or Automake's "missing") can tell the
9146 difference with a plain failure.
9147 * doc/autoconf.texi (Notices): Adjust.
9149 2003-05-23 Akim Demaille <akim@epita.fr>
9151 * Makefile.am, bin/Makefile.am, config/Makefile.am,
9152 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
9153 White spaces cleanup.
9155 2003-05-22 Jim Meyering <jim@meyering.net>
9156 Paul Eggert <eggert@twinsun.com>
9158 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
9159 Remove `#include <stdlib.h>' from the list; we should never
9160 make confdefs.h include <stdlib.h> or <cstdlib>, because the
9161 resulting namespace pollution would cause other tests to fail.
9162 Configure scripts run with some older versions of g++ and HP's
9163 aCC would fail due to such an #include. Problems reported by
9164 Matthew Mueller in <http://bugs.debian.org/120704> and by
9165 Keith Bostic in
9166 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
9167 In the test, use the test declaration before including <stdlib.h>,
9168 as that's closer to how it'll be used.
9170 2003-05-23 Akim Demaille <akim@epita.fr>
9172 * doc/autoconf.texi (Header Portability): ucred.h.
9173 From Ian Redfern.
9175 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
9177 Overhaul Autotest's logging: generate separate log files
9178 in testsuite.dir/NNN/testsuite.log, and append them to
9179 testsuite.log instead of re-running the test verbosely.
9181 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
9182 file descriptor, write 0 to at_status_file instead of setting
9183 at_status=0, initialize some new variables (at_status_file,
9184 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
9185 to rerun the tests, instead append the at_group_log to the
9186 at_suite_log when a test fails.
9187 (AT_SETUP): pipe the test case's output into at_tee_pipe,
9188 with the AS_MESSAGE_LOG_FD redirected to stdout.
9189 (AT_CLEANUP): save the output status in $at_status_file
9190 and restore it, redirect the AS_MESSAGE_LOG_FD back to
9191 its original place.
9192 (AT_CHECK): since tests are run with a redirected stdout,
9193 and used to be re-run in verbose mode, turn some $at_verbose
9194 into echo, and don't redirect the output of testing stdout
9195 and stderr.
9197 * lib/autotest/autoconf.texi (testsuite Scripts): Update
9198 the name of the debugging directory and information about
9199 its contents.
9201 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
9203 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd

9316 and truncate.
9318 2003-05-06 Akim Demaille <akim@epita.fr>
9320 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
9321 longer updates aclocal.m4 if useless, (ii) if a file m4_included
9322 by aclocal.m4 is changed it might require the importing of another
9323 m4 extension file, i.e., aclocal must be run.
9325 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
9326 (&parse_args): Use --force with aclocal if required and supported.

9334 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
9335 argument instead of a file name, so that the request file remains
9336 open during the whole autom4te run.
9337 ($icache_file): New.
9338 (&freeze): Lock the $icache_file.
9340 2003-04-29 Derek Price <derek@ximbiot.com>
9342 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
9343 seperator with m4_append_uniq(). It doesn't work.
9344 (AT_CLEANUP): Add `;' to end of at_help_all.
9345 (AT_INIT): Allow --keywords to be specified more than once. When
9346 grepping $at_help_all for keywords, use the field and keyword
9347 seperators to ensure a complete keyword match. Alter at_prev handling
9348 to support the new --keywords behavior.
9350 2003-04-27 Karl Berry <karl@freefriends.org>
9352 * doc/autoconf.texi: Make the dir entries in the autoconf manual
9353 align better with others. I also made some of the individual
9354 entries on one line, for brevity and to make it easier for me to
9355 sort my dir-example file in the Texinfo distribution :).

9575 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
9576 innocuous variant befor including <limits.h> or <assert.h>. This
9577 works around a bug reported by Albert Chin: HP-UX 11i
9578 (and earlier versions) have a <limits.h> that declares
9579 gettimeofday and many other functions.
9581 2002-12-03 Paul Eggert <eggert@twinsun.com>

9592 Martin Frydl in
9593 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
9595 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
9596 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
9597 defined, to support freestanding compilers. This should fix the
9598 bug reported by Momchil Velkov in
9599 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
9601 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

9607 * Makefile.maint (www-gnu): New macro.
9608 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
9609 the location has moved.
9611 2002-12-02 Martin Frydl <martin@systinet.com>
9613 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
9614 \(.*\) match is too long and there is something more to be checked.
9615 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

9635 2002-11-14 Akim Demaille <akim@epita.fr>
9637 * Makefile.maint: Sync with Bison, i.e.:
9638 (po-check): Scan .l and .y files instead of the
9639 .c and the .h files that they generate. This fixes the bug
9640 reported by Tim Van Holder in:
9641 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
9642 Look for N_ as well as for _. Try to avoid matching #define for
9643 N_ and _.
9644 From Paul Eggert.

9699 2002-11-05 Akim Demaille <akim@epita.fr>
9701 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
9702 Remove.
9703 We _have_ to stop using the old compatibility scheme that tried to
9704 avoid useless backslashes because Libtool 1.4.3 contains a
9705 AC_DEFINE([error_t], [int],
9706 [Define to a type to use for \`error_t' if it is not
9707 otherwise available.])
9708 We _have_ to quote the single quote and backslashes with \. The
9709 old compatibility scheme saw that ` was backslashed, and therefore
9710 did not quote the single quote. Hence before this patch, Autoconf
9711 was not compatible with Libtool.

10102 Reported by Alexandre Duret-Lutz.
10104 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

10147 2002-10-11 Akim Demaille <akim@epita.fr>
10149 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
10150 Suggest using AC_CHECK_DECLS instead.
10152 2002-10-11 Akim Demaille <akim@epita.fr>
10154 * tests/torture.at (AC_ARG_VAR): Have configure report the value
10155 of `precious'.
10157 2002-10-11 Akim Demaille <akim@epita.fr>
10159 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
10160 file name to enable parallel executions.
10161 From Sam Varshavchik.
10163 2002-10-08 Akim Demaille <akim@epita.fr>
10165 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
10166 aclocal invocation, as Gettext macros might not be visible to
10167 aclocal.
10168 Instead of blindly running autopoint, scan configure.ac (not the
10169 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
10170 Reported by Paul D. Smith.
10172 2002-10-08 Paul Eggert <eggert@twinsun.com>
10174 Work around problems found when POSIXLY_CORRECT=1 is set.
10175 None of this seems to have anything to do with POSIX, really,
10176 but it's how Perl getopt works.
10177 * bin/autom4te.in (parse_args): Configure GetOpt with
10178 "permute", too.
10179 * doc/autoconf.texi (Invoking autom4te):
10180 --warning -> --warnings.
10181 * lib/autom4te.in: --warning -> --warnings.
10183 2002-09-28 Akim Demaille <akim@epita.fr>
10185 * doc/autoconf.texi (autom4te.cache): New section.
10187 2002-09-28 Akim Demaille <akim@epita.fr>
10189 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
10190 (Automake-preselections): Update.
10191 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
10193 2002-09-28 Akim Demaille <akim@epita.fr>
10195 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
10196 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
10197 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10198 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
10200 2002-09-28 Akim Demaille <akim@epita.fr>
10202 * tests/torture.at (Configuring subdirectories): Be robust to
10203 users who use config.site to require for a cache: in this case,
10204 the two last configure runs, using two different sets of
10205 arguments, trigger a legitimate error.
10207 2002-09-28 Akim Demaille <akim@epita.fr>
10209 * tests/m4sh.at (Functions Support, Functions and return Support):
10210 New.
10212 2002-09-28 Akim Demaille <akim@epita.fr>
10214 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
10215 autoheader are Perl programs.
10216 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
10217 (autom4te): Specify that the sources are in the $srcdir.
10218 * doc/autoconf.texi (Installation Directory Variables): Adjust.
10220 2002-09-28 Akim Demaille <akim@epita.fr>
10222 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
10223 (tm_zone): Move their rules to...
10224 * lib/autoconf/types.m4: here, using AN_ macros.
10225 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
10226 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
10227 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
10228 * lib/autoconf/programs.m4: here.
10229 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
10230 (ETAGS_FOR_AUTOCONF): New.
10231 Use it.
10233 2002-09-28 Akim Demaille <akim@epita.fr>
10235 * lib/autoconf/autoscan.m4: New file.
10236 * lib/autoconf/autoconf.m4: Include it.
10237 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
10238 that were listed in the original autoscan.list.
10239 * lib/autoconf/headers.m4: Similarly with headers.
10240 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
10241 (.m4.m4f): Don't pass --prepend-include, since that's done by
10242 tests/autom4te itself.
10243 * lib/autoscan/Makefile.am: Include freeze.mk.
10244 (autoscan.list): New target --this file is no longer a source.
10245 (autoscan.pre): New file.
10247 2002-09-28 Akim Demaille <akim@epita.fr>
10249 * bin/autoscan.in (@kinds): Make them singular.
10250 Adjust all uses.
10251 (&init_tables): When --debug, report the list of rules to ease
10252 tracking changes in autoscan.list.
10253 * lib/autoscan/autoscan.list (function): Strip comments, sort.
10255 2002-09-28 Akim Demaille <akim@epita.fr>
10257 * lib/autoscan/functions, lib/autoscan/headers,
10258 * lib/autoscan/identifiers, lib/autoscan/makevars,
10259 * lib/autoscan/programs: Merge into...
10260 * lib/autoscan/autoscan.list: this.
10261 * bin/autoscan.in (&init_tables): Adjust.
10263 2002-09-28 Akim Demaille <akim@epita.fr>
10265 * lib/autoscan/functions, lib/autoscan/headers,
10266 * lib/autoscan/identifiers, lib/autoscan/makevars,
10267 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
10268 `functions' line is now prefixed with `function:'.
10269 * bin/autoscan.in (&init_tables): Adjust.
10271 2002-09-28 Akim Demaille <akim@epita.fr>
10273 From now on, autoscan files must always map a macro name to a
10274 word: there is no `default' macro for autoscan.
10276 * bin/autoscan.in (&init_tables): Reject entries with no macro at
10277 all.
10278 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
10279 explicit.
10281 2002-09-28 Akim Demaille <akim@epita.fr>
10283 * bin/autoscan.in (%c_keywords): Remove.
10284 (&used): Keep only track of the words we might be interested in.
10285 (&output_kind): It is no longer needed to look for non active
10286 checks.
10288 2002-09-27 Akim Demaille <akim@epita.fr>
10290 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
10291 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
10292 * lib/autoscan/functions: Adjust.
10293 * doc/autoconf.texi (Particular Functions): Adjust.
10295 2002-09-27 Akim Demaille <akim@epita.fr>
10297 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
10298 from /tmp.
10299 Thanks to Bill Moseley and Paul Eggert.
10300 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
10301 the tmpdir must be created.
10302 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
10303 dir be in the build tree, instead of $TMPDIR.
10305 2002-09-27 Akim Demaille <akim@epita.fr>
10307 * bin/autoscan.in: Improve the comments.
10308 (&parse_args): Drop obsolete undocumented options.
10309 (&output_kind): Output warnings.
10310 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
10311 (getwd): Trigger a warning.
10313 2002-09-26 Akim Demaille <akim@epita.fr>
10315 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
10316 Reported by Ralf Corsepius.
10317 * doc/autoconf.texi (autoreconf Invocation): Likewise.
10319 2002-09-26 Akim Demaille <akim@epita.fr>
10321 Single suffix rules and seperated dependencies are not portable.
10323 * doc/autoconf.texi (Installation Directory Variables): Update.
10324 (Limitations of Make): Some about `Single Suffix Rules and
10325 Separated Dependencies'.
10326 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10327 (ifnames, autoscan, autom4te): Un-factor into several rules.
10329 2002-09-25 Paul Eggert <eggert@twinsun.com>
10331 * BUGS (Interoperability bugs): New section. Mention libtool
10332 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
10334 2002-09-24 Paul Eggert <eggert@twinsun.com>
10336 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
10337 make handles suffix-rules differently from GNU make.
10339 * bin/Makefile.am (SUFFIXES, .in): Remove.
10340 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
10341 Move the body of the old .in rule here.
10343 2002-09-16 Akim Demaille <akim@epita.fr>
10345 i960 compilers create `b.out' files by default.
10346 Reported by Ralf Corsepius.
10348 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
10349 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
10351 2002-09-13 Paul Eggert <eggert@twinsun.com>
10353 * doc/autoconf.texi (Particular Headers): Remove obsolete
10354 reference to `struct timezone' in the description of
10355 AC_HEADER_TIME.
10357 2002-09-13 Akim Demaille <akim@epita.fr>
10359 Version 2.54.
10361 * config/config.sub, config/config.guess: Update.
10362 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
10363 * Makefile.am: Adjust.
10365 2002-09-13 Akim Demaille <akim@epita.fr>
10367 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
10368 reading config.log when the compiler is rejected.
10369 Suggested by Guido Draheim.
10371 2002-09-13 Akim Demaille <akim@epita.fr>
10373 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
10374 (chdir_init) might hang when stat'ing mounted directories.
10375 Reported by Vance Shipley.
10377 2002-09-12 Akim Demaille <akim@epita.fr>
10379 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
10380 the lists.
10382 2002-09-12 Akim Demaille <akim@epita.fr>
10384 * doc/autoconf.texi (Defining Symbols): Present two different
10385 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
10386 difference between 1 argument calls, and 2-3 argument calls.
10388 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
10390 * doc/autoconf.texi: Review grammar and punctuation.
10392 2002-09-11 Paul Eggert <eggert@twinsun.com>
10394 * doc/autoconf.texi: Fix minor formatting, spelling, and
10395 grammatical typos.
10396 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
10397 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
10398 is obsolescent.
10400 2002-09-11 Akim Demaille <akim@epita.fr>
10402 * doc/autoconf.texi (Questions): Rename as...
10403 (FAQ): this.
10404 (Defining Directories): New.
10406 2002-09-09 Akim Demaille <akim@epita.fr>
10408 * doc/autoconf.texi (Making testsuite Scripts): Update.
10409 Suggested by Nishio Futoshi.
10411 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
10413 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
10414 plain `@' is wanted.
10416 2002-09-09 Akim Demaille <akim@epita.fr>
10418 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
10419 `duplicates', since the algorithm was too naive and could keep
10420 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
10421 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
10422 Reported by Ralf Corsepius.
10423 * tests/torture.at (Configuring subdirectories): Exercise these
10424 cases.
10426 2002-09-09 Akim Demaille <akim@epita.fr>
10428 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
10429 looking for a replacement file.
10430 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
10431 directory is relative.
10432 * doc/autoconf.texi (Generic Functions): Clarify the replacement
10433 directory definition.
10434 Reported by Andreas Schwab and Jim Meyering.
10436 2002-09-06 Akim Demaille <akim@epita.fr>
10438 * doc/autoconf.texi (Setting Output Variables): Clarify what
10439 precious variables are.
10440 Suggested by Pontus Skoeld.
10442 2002-09-05 Akim Demaille <akim@epita.fr>
10444 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10445 (ifnames, autoscan, autom4te): Since we don't only depend on
10446 configure.ac variables (such as VERSION etc.), but also on prefix
10447 and so forth, depend on Makefile, not configure.ac.
10448 Reported by Alexandre Duret-Lutz.
10449 * doc/autoconf.texi (Installation Directory Variables): Adjust.
10451 2002-09-05 Kevin Ryde <user42@zip.com.au>
10453 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
10454 doesn't seem to be confined to ia64, just say "some versions".
10456 2002-09-04 Akim Demaille <akim@epita.fr>
10458 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
10459 Automake 1.6c.
10460 * Makefile.am (maintainer-clean-local): Remove.
10461 (MAINTAINERCLEANFILES): Remove COPYING.
10463 2002-09-03 Paul Eggert <eggert@twinsun.com>
10465 * doc/autoconf.texi (Configuration Commands): Remove obsolete
10466 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
10467 Brinkmann.
10469 2002-09-03 Akim Demaille <akim@epita.fr>
10471 * configure.ac: Bump to 2.53d.
10472 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
10473 as of today, on Automake's team suggestion.
10475 2002-09-03 Akim Demaille <akim@epita.fr>
10477 Version 2.53c.
10479 2002-09-02 Akim Demaille <akim@epita.fr>
10481 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
10482 SITE_MACRO_DIR.
10483 * configure.ac: Disable SITE_MACRO_DIR.
10485 2002-09-02 Jim Meyering <meyering@lucent.com>
10487 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
10488 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
10489 Also, tweak grammar: s/make sure to/be sure to/.
10491 2002-09-02 Paul Eggert <eggert@twinsun.com>
10493 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
10494 directory names are generally preferable to physical names.
10496 2002-09-02 Akim Demaille <akim@epita.fr>
10498 * lib/Autom4te/General.pm (&update_file): s/die/error/.
10499 Reported by Raja R. Harinath.
10500 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
10501 * bin/autoupdate.in: Use error instead of die.
10503 2002-09-01 Paul Eggert <eggert@twinsun.com>
10505 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
10506 ordinary shell concatenation rather than echo+tr+sed command that
10507 runs afoul of a long-line-related sed bug in Solaris 8.
10509 * bin/autoheader.in (parse_args): --warning -> --warnings.
10511 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
10512 stdout, as traditional "ls" does.
10513 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
10514 _AC_COMPILER_EXEEXT_O): Likewise.
10515 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
10517 * bin/autoconf.as: Add --prepend-include option. This patch was
10518 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
10519 but bin/autoconf.in is generated automatically from bin/autoconf.as.
10521 * bin/autoconf.in, configure: Regenerate.
10523 * doc/autoconf.texi (Special Shell Variables): Mention
10524 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
10526 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
10527 MAILPATH and set PS1, PS2, PS4 to default values, to work
10528 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
10529 For LC_ALL etc, first try to set to "C" as POSIX requires and as
10530 the Autoconf documentation specifies; fall back to "unset" only if
10531 this fails. Use a shell for-loop for this rather than an m4 loop,
10532 to shorten the output script.
10534 2002-08-30 Paul Eggert <eggert@twinsun.com>
10536 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
10537 1003.1-2001's requirements for CDPATH. Give a simpler workaround
10538 for the CDPATH problem. Document PWD.
10539 (Limitations of Builtins): Document the problem that "cd $foo" and
10540 "ls $foo" may refer to different directories in shells conforming
10541 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
10542 example, since the old example is now out of date.
10544 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
10545 FOO" and "ls FOO" talk about different directories; this catches
10546 problems when POSIX 1003.1-2001 "cd" fails due to symlink
10547 spaghetti.
10549 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
10550 of rolling our own unset.
10551 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
10552 in practice we needn't worry about CDPATH if unset doesn't work.
10554 * Makefile.in, aclocal.m4, bin/Makefile.in,
10555 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
10556 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
10557 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
10558 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
10559 tests/Makefile.in: Regenerate with Automake 1.6.3.
10561 * config/config.guess, config/config.sub, config/mkinstalldirs:
10562 Update.
10564 * configure: Regenerate with self.
10566 2002-08-30 Kevin Ryde <user42@zip.com.au>
10568 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
10569 default output.
10571 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
10573 * bin/autom4te.in (Request::load): Correctly test for "do" read
10574 failure.
10576 2002-08-29 Akim Demaille <akim@epita.fr>
10578 * lib/Autom4te/General.pm (&xqx): New.
10579 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
10580 hand, which is not portable.
10581 (&error): New.
10582 * bin/autom4te.in: Use them.
10583 Use &error instead of die.
10584 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
10585 Adjust.
10587 2002-08-17 Paul Eggert <eggert@twinsun.com>
10589 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
10590 default list of compilers to try, since it was long ago superseded
10591 by the ksh fc builtin. Suggested by Steven G. Johnson.
10593 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
10595 * doc/autoconf.texi (Invoking autom4te): End the option table,
10596 fixing a bug introduced by the previous patch.
10597 (Limitations of Make): Add a 'target lookup' subentry in the
10598 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
10600 2002-07-29 Mark D. Roth <roth@feep.net>
10602 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
10603 options and use $AUTOM4TE_PATH.
10604 * doc/autoconf.texi: Remove documentation of autom4te
10605 --include-envvar and --site-macro-subdir options and document
10606 use of $AUTOM4TE_PATH.
10607 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
10608 arguments from each language section.
10610 2002-07-29 Paul Eggert <eggert@twinsun.com>
10612 * doc/install.texi: Include copyright symbol in copyright notice.
10614 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
10615 Replace with:
10616 (AM_MAKEINFOFLAGS): New macro.
10617 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
10618 * Makefile.am (INSTALL): Use the new macros.

10623 * doc/autoconf.texi (Limitations of Make): Escaped newlines in

10634 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
10635 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002

10771 "Limitations of Builtins".
10773 2002-06-15 Paul Eggert <eggert@twinsun.com>
10775 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
10776 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
10777 so that we consistently test the just-built programs.
10778 * tests/wrappl.as: Likewise.
10780 2002-06-12 Paul Eggert <eggert@twinsun.com>

10794 2002-06-11 Andreas Schwab <schwab@suse.de>
10796 * doc/autoconf.texi: Add more dir entries.
10798 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
10800 * bin/autom4te.in ($cache): Don't define using `$me', the name
10801 of the cache should not depend on the name under which autom4te
10802 was installed.
10804 2002-06-07 Akim Demaille <akim@epita.fr>

10832 Suggested by Adam J. Richter.
10834 2002-06-07 Akim Demaille <akim@epita.fr>
10836 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
10837 ac_config_libobj_dir.
10838 (AC_CONFIG_LIBOBJ_DIR): New.
10839 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

10841 Use ac_config_libobj_dir to find the replacement files.
10842 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...

10846 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
10847 * tests/mktests.sh (ac_exclude_list): Don't check

10897 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
10898 from the default list of compilers to try. Suggested by
10899 Kate Hedstrom.
10900 * NEWS: Document the above.
10901 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
10903 2002-05-17 Paul Eggert <eggert@twinsun.com>
10905 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
10906 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
10907 This improves on an earlier suggestion by H. Peter Anvin.
10909 2002-05-16 Paul Eggert <eggert@twinsun.com>
10911 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
10912 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
10913 Both macros now accept an optional source-dir arg.
10914 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
10916 * NEWS: Document this.
10917 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
10919 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
10920 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
10921 not for GNU extensions; this undoes part of the 2000-11-03 change,
10922 reverting to 2.13-compatible behavior.
10923 Add new optional argument DIR.
10924 (AC_FUNC_FNMATCH_GNU): New macro.
10926 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
10928 2002-05-08 Paul Eggert <eggert@twinsun.com>
10930 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
10931 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
10932 and it causes a 'test' syntax error if it fails.
10933 Bug reported by Stephen Gildea.
10935 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
10936 If prototypes are supported, use them to check this at compile-time,
10937 instead of trying to check it at run-time. If we must do a run-time
10938 check, assume that setvbuf is standard when cross-compiling, as
10939 nonstandard setvbuf occurs only on ancient and unlikely hosts.
10940 Bug reported by Paul D. Smith.
10942 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
10943 argument specifying location of getloadavg.c. This removes a
10944 FIXME. This idea was taken from Jim Meyering's implementation in
10945 textutils.
10946 * doc/autoconf.texi (Particular Functions): Document this.
10947 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
10948 that's what the code does; this fixes a bug reported by
10949 Paul D. Smith.
10951 2002-05-03 Akim Demaille <akim@epita.fr>
10953 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
10954 autopoint instead of gettextize.
10955 ($uses_alocal): Rename as...
10956 ($uses_aclocal): this.
10957 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10958 Suggested by Bruno Haible.
10960 2002-05-03 Akim Demaille <akim@epita.fr>
10962 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
10964 2002-04-29 Paul Eggert <eggert@twinsun.com>
10966 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
10967 files to be 1 second older; just set them to be the same time.
10968 Also, sleep 1 second after the first aclocal, to work around
10969 problems with sub-second time stamps on the input files.
10971 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
10973 * doc/autoconf.texi: Mention "set -e -x" lossage
10974 under node "Limitations of Builtins".
10976 2002-04-29 Akim Demaille <akim@epita.fr>
10978 * doc/install.texi: Better wording for setting variables when
10979 running configure.
10980 From Christian Cornelssen.
10982 2002-04-29 Akim Demaille <akim@epita.fr>
10984 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
10985 of lack of $LINENO support, then the test will compare the $LINENO
10986 in testsuite vs. the lineno in the test file. This is wrong, of
10987 course.
10988 Be sure to protect it.
10989 Reported by Patrick Welche.
10991 2002-04-25 Akim Demaille <akim@epita.fr>
10993 * doc/autoconf.texi (Obsolete Macros): Typo.
10994 Reported by Vladimir Volovich.
10996 2002-04-25 Akim Demaille <akim@epita.fr>
10998 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
10999 than some of the input files, hence, on the second run of aclocal,
11000 if some of its input are younger, make them older.
11001 Suggested by Paul Eggert.
11003 2002-04-25 Akim Demaille <akim@epita.fr>
11005 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
11006 Thanks to Paul Eggert.
11008 2002-04-25 Akim Demaille <akim@epita.fr>
11010 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
11011 and ac_subst_vars be sh variables containing the list of
11012 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
11013 DEFAULT diversion.
11014 (_AC_INIT_PREPARE): Use them to log them.
11015 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
11016 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
11017 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
11018 _AC_SUBST_FILES and _AC_SUBST_VARS.
11019 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
11021 2002-04-24 Akim Demaille <akim@epita.fr>
11023 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
11024 autoheader, so that automake does not complain about a missing
11025 config.h.in that was to be created.
11027 2002-04-23 Akim Demaille <akim@epita.fr>
11029 * bin/autoheader.in (parse_args): --warning takes an argument.

11078 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
11079 Minor spelling and grammar fixes.
11081 * doc/autoconf.texi: Follow the outline suggested in the GNU
11082 Sample Texts sections of the Texinfo 4.2 manual. Most
11083 importantly, this makes sure that the copyright notices appear in
11084 all output formats. You probably need Texinfo 4.2 to generate
11085 the manual now.
11087 Fix some bugs when using "$@" when there might be zero positional
11088 arguments in cases where this matters.
11090 * bin/autoconf.as: Rewrite so that the problem does not come up.

11102 * doc/autoconf.texi (Shell Substitutions): Document the problem.
11104 * lib/autotest/general.m4 (AT_INIT):
11105 Use Zsh alias to work around problem.
11106 * tests/atgeneral.m4 (AT_INIT): Likewise.
11108 * tests/c.at: We can't have zero arguments, so remove workaround
11109 that is not portable to Zsh.
11111 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
11113 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

11123 workaround for ${1+"$@"}.
11124 * doc/autoconf.texi (Shell Substitutions): Explain it.
11125 From Oliver Kiddle and Peter Stephenson.
11127 Have M4sh perform minimal shell sanitizing.
11129 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
11130 part into...
11131 (_AS_PREPARE): this new macro.
11132 (AS_PREPARE): New.
11133 (AS_INIT): Invoke AS_SHELL_SANITIZE.
11134 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
11136 Adjust Autoconf and Autotest.
11138 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
11139 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
11140 * lib/autotest/general.m4 (AT_INIT): Likewise.
11141 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
11142 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
11143 AS_SHELL_SANITIZE.
11145 Use this M4sh to generate Autoconf's shell scripts.
11147 * tests/wrapsh.as: New, precursor of wrapsh.in.
11148 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
11149 on Autotest and M4sh.
11150 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
11151 (wrapsh.in): New target.
11152 * bin/autoconf.as: New, precursor of autoconf.in.
11153 (autoconf.in): New target.
11155 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
11157 * doc/autoconf.texi (Limitations of Make): Mention the issue
11158 with indented comments in rules.
11160 2002-04-09 Andreas Schwab <schwab@suse.de>
11162 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
11163 ac_top_builddir when setting ac_abs_top_builddir.
11165 2002-04-06 Kevin Ryde <user42@zip.com.au>
11167 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
11168 (Portable Shell): Cross reference to Systemology.
11170 2002-04-05 Akim Demaille <akim@epita.fr>
11172 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
11173 directories when descending in a SUBDIRS.
11174 Reported by Ezra Peisach.
11176 2002-04-04 Andreas Schwab <schwab@suse.de>
11178 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
11179 contains no literal separators.
11181 2002-04-03 Akim Demaille <akim@epita.fr>
11183 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
11184 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
11185 Use dnl, not the KILL diversion.
11186 Extracted from...
11187 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
11188 (AC_CONFIG_LINKS): here.
11189 Adjust.
11190 Don't use the KILL diversion, as it kills spurious output, which
11191 results in failures being hidden.
11192 Use m4_defn where appropriate.
11193 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
11194 after the second argument.
11195 Use m4_defn.
11196 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
11197 syntax, as it is provided by M4sugar.
11198 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
11200 2002-04-03 Andreas Schwab <schwab@suse.de>
11202 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
11203 expanded if $# <= 2.
11205 * bin/autoreconf.in (autoreconf): Run automake after rerunning
11206 aclocal.
11208 2002-04-03 Akim Demaille <akim@epita.fr>

11212 Also recognize *.bb and *.bbg as compilation byproducts.
11213 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
11214 (_AC_COMPILER_OBJEXT): Use them.
11215 Fixes Debian #138666.
11217 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
11219 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
11221 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
11222 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
11223 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
11224 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
11225 (AC_C_CONST): Same.
11226 (AC_C_INLINE): Same.
11227 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
11228 * doc/autoconf.texi, NEWS: Document.
11229 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
11230 AC_C_CROSS.

11237 2002-03-28 Kevin Ryde <user42@zip.com.au>
11239 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
11240 to avoid versions of HP C which don't allow that.
11242 2002-03-27 Paul Eggert <eggert@twinsun.com>
11244 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
11245 (AS_SHELL_SANITIZE): Invoke it.
11246 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
11248 2002-03-26 Akim Demaille <akim@epita.fr>
11250 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
11252 2002-03-26 Akim Demaille <akim@epita.fr>
11254 * doc/autoconf.texi (Introduction): The GNATS base moved.
11256 2002-03-25 Paul Eggert <eggert@twinsun.com>
11258 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
11259 as POSIX requires, as it doesn't work with Zsh.
11260 * doc/autoconf.texi (Assignments): Document the problem.
11262 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11264 * doc/autoconf.texi (Limitations of Make): Mention more issue
11265 about VPATH, overriding of macros in sub-makes, and handling of
11266 SHELL.
11268 2002-03-21 Paul Eggert <eggert@twinsun.com>
11270 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
11271 problem with here-document buffer boundaries.
11273 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
11274 when reinvoking the shell, to work around problems with installers
11275 who put strange things like "cd" commands in their environments.
11277 2002-03-19 Akim Demaille <akim@epita.fr>
11279 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
11280 From Aaron Ucko.
11282 2002-03-19 Akim Demaille <akim@epita.fr>
11284 * bin/autoscan.in (scan_file): Specify the location in `&used'
11285 invocations.
11286 From Nicolas Joly.
11288 2002-03-19 Akim Demaille <akim@epita.fr>
11290 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
11291 From Nishio Futoshi.
11293 2002-03-19 Akim Demaille <akim@epita.fr>
11295 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
11297 2002-03-18 Paul Eggert <eggert@twinsun.com>
11299 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
11300 (Limitations of Usual Tools): Add mkdir section.
11302 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
11303 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
11304 back on AS_DIRNAME to compute prefixes otherwise; this is
11305 roughly what mkinstalldirs does. That way, we need not have
11306 our own filename disassembler. The old disassembler did not
11307 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
11309 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
11310 Create at_test_all by a series of assignments,
11311 not by a single assignment of a long string. The latter causes ksh
11312 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
11313 presumably because of a buffer overrun.
11315 2002-03-14 Paul Eggert <eggert@twinsun.com>
11317 * lib/autotest/general.m4 (at_times_skip):
11318 Renamed from at_times. Now a boolean.
11319 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
11320 says 'times: not found'.
11322 2002-03-14 Akim Demaille <akim@epita.fr>
11324 * bin/autoreconf.in (&study_gettextize): New.
11325 (&autoreconf): Handle newest gettextize.
11326 Rerun aclocal if needed.
11327 Suggested by Andreas Schwab.
11329 2002-03-13 Akim Demaille <akim@epita.fr>
11331 * doc/autoconf.texi (Special Shell Variables): More about IFS.
11333 2002-03-13 Akim Demaille <akim@epita.fr>
11335 * doc/autoconf.texi (Header Portability): New.
11336 Add information about stdint.h and inttypes.h from Paul Eggert.
11338 2002-03-13 Akim Demaille <akim@epita.fr>
11340 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
11341 -p'.
11342 From Bob Proulx.
11344 2002-03-12 Akim Demaille <akim@epita.fr>
11346 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
11347 m4_require.
11349 2002-03-11 Andreas Schwab <schwab@suse.de>
11351 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
11352 does not do it if --with-lispdir is given.
11354 2002-03-08 Akim Demaille <akim@epita.fr>
11356 Version 2.53.
11358 2002-03-08 Akim Demaille <akim@epita.fr>
11360 * doc/autoconf.texi (Subdirectories): Clarify that the
11361 subdirectory should exist.
11363 2002-03-08 Akim Demaille <akim@epita.fr>
11365 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
11367 2002-03-08 Akim Demaille <akim@epita.fr>
11369 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
11370 aliases the actual variables, and modifications of the former
11371 affect the latter.
11373 2002-03-08 Akim Demaille <akim@epita.fr>
11375 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
11376 because of C-c: have m4 output in tmp files, then mv them.
11378 2002-03-08 Akim Demaille <akim@epita.fr>
11380 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
11381 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
11382 * bin/ifnames.in: Copyright update.
11384 2002-03-08 Akim Demaille <akim@epita.fr>
11386 * doc/autoconf.texi (Invoking autom4te): New.
11388 2002-03-05 Akim Demaille <akim@epita.fr>
11390 * doc/autoconf.texi (Specifying Names): Clarification suggested by
11391 Kevin Ryde.
11393 2002-03-05 Akim Demaille <akim@epita.fr>
11395 Version 2.52i.
11397 2002-03-04 Akim Demaille <akim@epita.fr>
11399 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
11400 * lib/autoconf/general.m4 (AC_INIT): More informative error
11401 message for LIBOBJ.
11403 2002-03-04 Akim Demaille <akim@epita.fr>
11405 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
11406 parallel builds.
11408 2002-03-04 Akim Demaille <akim@epita.fr>
11410 * doc/autoconf.texi (Transforming Names): Equality between target
11411 and host is irrelevant.
11412 (Specifying Names, Canonicalizing): Remove all references to the
11413 backward compatibility hooks. Rather, collect them all into...
11414 (Hosts and Cross-Compilation): this new section.
11415 * doc/install.texi (System Type): Ditto.
11416 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
11417 that `--host' implies cross-compilation.
11419 2002-03-04 Akim Demaille <akim@epita.fr>
11421 * doc/autoconf.texi (Evaluation Macros): New.
11422 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
11423 useless.
11424 (_m4_foreach): Define the variant with immediate evaluation so
11425 that it contains exactly the items, not an expression which
11426 evaluation is the current item.
11427 (m4_re_string, m4_re_word): Don't over quote them.
11429 2002-03-04 Akim Demaille <akim@epita.fr>
11431 Instead of having stacking `shift's evaluated at the end, let
11432 `foreach' loops immediately evaluate them.
11434 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
11435 $*. This is the n-th time I change my mind, but hopefully this is
11436 the last...
11437 (m4_lquote): New.
11438 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
11439 efficient.
11440 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
11441 it was only a hack for m4_text_wrap.
11442 (m4_car2): Remove, replaced by...
11443 (m4_cdr): New.
11444 (_m4_foreach): Adjust.
11445 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
11446 m4_bpatsubst for clarification.

11488 2002-02-07 Akim Demaille <akim@epita.fr>
11490 Fix Autoconf PR/209.
11491 Also reported by Frank Denis.
11493 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
11495 2002-02-07 Akim Demaille <akim@epita.fr>
11497 Fix Autoconf PR/207:
11498 AC_PREFIX_PROGRAM fails with dashed program names
11500 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
11501 variable when looking for the prefix program.

11513 Reported by Zack Weinberg.

11532 not unsigned long.
11533 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
11534 cross-compilers, too. This undoes some of the most recent change
11535 to this file.

11539 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

11557 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
11559 2002-02-05 Akim Demaille <akim@epita.fr>
11561 * bin/autom4te.in (&parse_args): Implement `frozen files are
11562 optional are the sum of the previous files on the command line'.
11563 Also, pass `--reload-state=' on them, so...
11564 (handle_m4): don't.
11565 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
11566 (M4sh): Rely on M4sugar.
11567 (Autotest, M4sh, M4sugar): Use frozen files.
11569 2002-01-31 Akim Demaille <akim@epita.fr>
11571 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
11572 * doc/autoconf.texi (Initializing configure): Adjust.
11574 2002-01-30 Akim Demaille <akim@epita.fr>
11576 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
11577 alphanumeric to `-' instead of `_'.
11579 2002-01-30 Akim Demaille <akim@epita.fr>
11581 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
11582 for plain code, the other for cross-compilation code. The latter
11583 is now run with GCC only.
11584 * doc/autoconf.texi (Compilers and Preprocessors): New.
11586 2002-01-30 Akim Demaille <akim@epita.fr>
11588 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
11589 values.
11590 * doc/autoconf.texi (Initializing configure): Explain how to
11591 change AC_INIT default values.
11593 2002-01-29 Akim Demaille <akim@epita.fr>
11595 * tests/torture.at (Configuring subdirectories): Use configure.in,
11596 so that aclocal 1.4 works.
11597 Reported by Alexandre Duret-Lutz and Larry Schmitt.
11599 2002-01-28 Akim Demaille <akim@epita.fr>
11601 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
11602 needs an argument.
11604 2002-01-28 Akim Demaille <akim@epita.fr>
11606 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
11607 AUTOTEST_PATH *after* it was set.
11608 Don't put `.' in the PATH: the user should be precise and `./' if
11609 needed. In addition, given that the test suite does some `cd', if
11610 `.' is in the path, the `tested programs' sections will report
11611 programs found in the test suite's directory, while during the
11612 tests (performed in their own directory), these programs are no
11613 longer visible. In other words, the results is confusing and
11614 useless.
11615 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
11617 2002-01-24 Akim Demaille <akim@epita.fr>
11619 Version 2.52g.
11621 2002-01-24 Akim Demaille <akim@epita.fr>
11623 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
11624 * doc/autoconf.texi: Finally add Akim as an author.
11626 2002-01-24 Akim Demaille <akim@epita.fr>
11628 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
11629 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
11630 Bourne. Use /bin/sh.
11631 From Andreas Buening.
11633 2002-01-24 Akim Demaille <akim@epita.fr>
11635 * config/config.guess, config/config.sub, config/texinfo.tex:
11636 Update from masters.

11643 * config/missing.m4, config/sanity.m4, config/select.m4,
11644 * config/strip.m4: Remove, to ease sync'ing with any version of
11645 Automake.
11647 2002-01-24 Akim Demaille <akim@epita.fr>
11649 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
11650 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
11651 Reported by Geir Ove Myhr.
11653 2002-01-21 Akim Demaille <akim@epita.fr>
11655 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
11657 2002-01-21 Akim Demaille <akim@epita.fr>
11659 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
11660 message on invalid options.
11661 * bin/autom4te.in (parse_args): Don't use
11662 Autoconf::General::getopt with non valid options.
11664 2002-01-17 Jim Meyering <meyering@lucent.com>
11666 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
11667 $ac_cv_exeext so we don't use an old, invalid, cached value.
11669 2002-01-11 Akim Demaille <akim@epita.fr>
11671 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
11672 Meyering.

11674 limitation.

11678 2002-01-06 Akim Demaille <akim@epita.fr>
11680 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
11681 package.m4, since is really depends upon configure.ac, not
11682 configure.
11683 * doc/autoconf.texi (testsuite Scripts): Adjust.
11684 * tests/Makefile.am (package.m4): New.
11685 EXTRA_DIST it since its a source.
11687 2002-01-06 Akim Demaille <akim@epita.fr>
11689 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
11690 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
11691 and PACKAGE_BUGREPORT from here...
11692 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
11693 arguments.
11694 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
11695 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
11696 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
11697 * tests/tools.at (autoheader): Adjust.
11698 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
11700 2002-01-06 Akim Demaille <akim@epita.fr>

11704 2002-01-03 Akim Demaille <akim@epita.fr>
11706 * doc/autoconf.texi (Output): Improved wording regarding use of
11707 AC_OUTPUT.
11708 From Olly Betts.
11710 2001-12-18 Kevin Ryde <user42@zip.com.au>
11712 * doc/autoconf.texi (Function Portability): Add notes on sscanf
11713 sometimes needing writable input.
11715 2001-12-17 Jim Meyering <meyering@lucent.com>
11717 * doc/autoconf.texi (New Macros): Tweak wording.
11719 2001-12-14 Akim Demaille <akim@epita.fr>
11721 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
11722 trailing files, don't apply `-rf' to files which might not be
11723 created by configure (core, core.*, and *.core), but just `rm -f'.
11724 Suggested by Jonathan Kamens.
11726 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
11728 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
11730 2001-12-14 Akim Demaille <akim@epita.fr>
11732 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
11734 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
11736 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
11737 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
11738 abs_srcdir, top_srcpath to abs_top_srcdir.
11739 (_AC_OUTPUT_FILES): Adjust.
11740 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
11741 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
11742 * tests/wrappl.in, tests/wrapsh.in: Adjust.
11744 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
11746 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
11747 C/Fortran linking on HP/UX, by extracting the Fortran library
11748 search path from the LPATH line in the $F77 -v output.
11750 2001-12-12 Kevin Ryde <user42@zip.com.au>
11752 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
11753 forbidden file descriptors table.
11755 2001-11-26 Akim Demaille <akim@epita.fr>
11757 * bin/autoscan.in (%c_keywords): Build it at top level.
11758 Map to 1 in order to simplify its uses.
11760 2001-11-26 Akim Demaille <akim@epita.fr>
11762 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
11763 Remove $filepath, useless.
11764 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
11765 variables, they are really part of the tokens.
11766 Split the input line on spaces and then look for tokens.
11767 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
11768 because of `lex$U.$(OBJEXT)'.
11769 (&scan_files): Use "@list" instead of join.
11770 * doc/Makefile.am (CLEANFILES): Add *.fns.
11772 2001-11-26 Akim Demaille <akim@epita.fr>
11774 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
11775 Remove, replaced by...
11776 * tests/wrappl.in: Be common for all the Perl executables.
11777 In particular autoscan and autoheader want -I.
11778 * configure.ac: Adjust.
11779 * lib/autoscan/headers: errno.h is portable.
11781 2001-11-26 Akim Demaille <akim@epita.fr>
11783 * bin/autoscan.in (used): New.
11784 Use it.
11786 2001-11-26 Akim Demaille <akim@epita.fr>
11788 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
11789 directives.
11790 (&scan_sh_file): Remove a duplicate pattern.
11791 (&check_configure_ac): Use long options.
11792 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
11794 2001-11-26 Akim Demaille <akim@epita.fr>
11796 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
11797 Before, having a line containing the opening of a multi line
11798 comment made the whole line be ignored.
11800 2001-11-26 Akim Demaille <akim@epita.fr>
11802 * doc/autoconf.texi (Using an Autotest Test Suite): New.
11803 (testsuite Scripts): Be one of its subsection.
11804 (Autotest Logs): New.
11806 2001-11-26 Akim Demaille <akim@epita.fr>
11808 Test groups are now run two directories deeper.
11810 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
11811 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
11812 at_top_builddir.
11813 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
11814 top_srcdir, builddir and top_builddir.
11815 Use `at_*dir' relatively to the directory containing the
11816 suite, use `*dir' when relatively to the current group dir.
11818 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
11820 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
11821 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
11822 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
11823 spelling errors.
11825 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11827 * doc/autoconf.texi (Using System Type): Add an example of `case
11828 $host' usage so people quit using `case $target' everywhere.
11830 2001-11-22 Akim Demaille <akim@epita.fr>
11832 * doc/autoconf.texi (Installation Directory Variables): Englishoes
11833 spotted by Jim Meyering.
11835 2001-11-16 Paul Eggert <eggert@twinsun.com>
11837 This patch implements a `long double' suggestion by Oliver Kiddle.
11839 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
11840 static, to catch errors if the value isn't known at compile-time
11841 and the compiler supports dynamic arrays. Change its name from
11842 `_array_' to `test_array' to avoid potential name clashes.
11843 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
11844 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
11845 better than double. Catch a bug in GCC 2.95.2 x86.
11846 * doc/autoconf.texi (C Compiler): Document the above.
11847 * NEWS: Likewise.
11849 2001-11-13 Akim Demaille <akim@epita.fr>
11851 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
11852 hand.
11853 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
11855 2001-11-13 Akim Demaille <akim@epita.fr>
11857 * lib/autotest/general.m4 (AT_INIT): After having run the test
11858 group, go back to the initial directory, not to at_suite_dir.
11860 2001-11-13 Akim Demaille <akim@epita.fr>
11862 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
11863 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
11864 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
11865 option.
11866 (AT_CHECK_CONFIGURE): Use absolute paths.
11867 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
11868 The problem is still the old one: there is no means in M4 (that I
11869 know about) to create a defining macro, because there is no means
11870 to create `$1' etc., therefore, the defining macro ``swallows''
11871 all the arguments meant to the defined macro.
11873 2001-11-13 Akim Demaille <akim@epita.fr>
11875 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
11876 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
11877 configure.ac.
11878 * tests/aclocal.m4: Remove, as it is no longer used.
11880 2001-11-13 Akim Demaille <akim@epita.fr>
11882 * lib/autotest/general.m4: Change `tests?' into `groups?' in
11883 variable names when referring to a single test group, or to
11884 `suite' when referring to the whole test suite.
11885 `at_last_test' is removed: m4 compute at_format itself.
11886 (at_stdout, at_stder1, at_stderr): New variables.
11887 (AT_CHECK): Use them.
11889 2001-11-13 Akim Demaille <akim@epita.fr>
11891 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
11892 in PATH.
11893 Create `testsuite.dir/003/run' instead of `testsuite.003'.
11894 Do it as soon as a test fails, don't wait till the end of the test
11895 suite.
11896 Don't remove $as_me.[0-9]*, since these files no longer exist.
11898 2001-11-13 Akim Demaille <akim@epita.fr>
11900 * tests/tools.at: Use absolute paths, since we are no longer run
11901 in place.
11903 2001-11-13 Akim Demaille <akim@epita.fr>
11905 Now that tests are running in their own private dir, there is no
11906 need to list the files to remove at the end of tests groups.
11908 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
11909 (AT_data_files, at_data_files): Remove.
11910 (AT_CLEANUP, AT_DATA): Simplify.
11911 (AT_INIT): Adjust.
11912 Remove the group dir if !debug && !failed.
11913 * tests/atspecific.m4: Adjust.
11915 2001-11-13 Akim Demaille <akim@epita.fr>
11917 Start a new layout for Autotest: `testsuite' creates
11918 `testsuite.dir' in which the at-check-line etc. files are to be
11919 found, and `testsuite.dir/003' where the test group 3 is run.
11921 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
11922 at_check_line_file, at_format, at_test_normalized, at_group_dir
11923 are new variables.
11924 Create the directories.
11925 Use absolute paths for at- files.
11926 (AT_CHECK): Adjust.
11928 2001-11-11 Michael Matz <matz@kde.org>
11930 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
11931 (m4_car2): New.
11932 (m4_car): Properly quote arguments.
11934 2001-11-13 Akim Demaille <akim@epita.fr>
11936 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
11937 with stricter rules on LIBOBJS.
11939 2001-11-12 Paul Eggert <eggert@twinsun.com>
11941 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
11942 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
11943 __PROTOTYPES too.
11945 2001-11-12 Akim Demaille <akim@epita.fr>
11947 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
11949 2001-11-12 Akim Demaille <akim@epita.fr>
11951 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
11952 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
11953 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11954 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
11955 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
11956 specify to what the macro should be defined (typically to 1).
11958 2001-11-12 Akim Demaille <akim@epita.fr>
11960 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
11961 From Jim Meyering.
11963 2001-11-12 Akim Demaille <akim@epita.fr>
11965 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11966 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
11967 definition used by Automake where LEX is +/- "${missing} lex" and
11968 `missing' itself contains variables.
11970 2001-11-12 Akim Demaille <akim@epita.fr>
11972 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
11973 Now that M4sh pushes BODY, the comments were output at the end of
11974 the test suites.
11976 2001-11-08 Akim Demaille <akim@epita.fr>
11978 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
11979 that we can trace macros from aclocal.m4.
11980 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
11981 obsoleted, and redirect to the former anyway.
11982 Reported by Ralf Corsepius.
11984 2001-11-08 Akim Demaille <akim@epita.fr>
11986 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
11987 processed only if present.
11988 * tests/torture.at (Configuring subdirectories): Use autoreconf
11989 instead of successive calls to autoconf.
11990 Add a nonexistent subdirectory to exercise the patch above.
11991 Reported by Ralf Corsepius.
11993 2001-11-08 Kevin Ryde <user42@zip.com.au>
11995 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
11996 doesn't accept .S files.
11998 2001-11-07 Akim Demaille <akim@epita.fr>
12000 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
12001 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
12002 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
12003 * bin/autom4te.in (warn_forbidden): New.
12004 (handle_output): Use it.
12005 Read m4_pattern_forbid with messages.
12007 2001-11-05 Akim Demaille <akim@epita.fr>
12009 * bin/autom4te.in (--normalize): Remove.
12010 * lib/autom4te.in: Adjust.
12012 2001-11-05 Akim Demaille <akim@epita.fr>
12014 * tests/Makefile.am (testsuite): Rename this target as...
12015 ($(TESTSUITE)): this.
12016 From Nicolas Joly.
12018 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
12020 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
12021 the --prefix option, also remove it's argument.
12023 2001-11-05 Akim Demaille <akim@epita.fr>
12025 * doc/autoconf.texi (testsuite Invocation): Update.
12026 (Writing testsuite.at): Update.
12028 2001-11-03 Akim Demaille <akim@epita.fr>
12030 * doc/autoconf.texi: s/@code/@command/ where appropriate.
12032 2001-11-03 Akim Demaille <akim@epita.fr>
12034 * lib/Autom4te/General.pm: (&catfile, &canonfile)
12035 (&file_name_is_absolute): New, wrappers around routines from
12036 File::Spec.
12037 Use and export them.
12038 (&find_configure_ac): Optionally take a directory where to look at.
12039 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
12040 the arguments.
12041 Default @ARGV to `.', not find_configure_ac.

12049 (@export_forward_subs): New.
12050 Add basename, dirname, and fileparse.
12051 (@EXPORT): Adjust.
12052 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
12053 Don't look for aclocal flags if we already know aclocal is not
12054 used.
12055 Move aclocal.m4t only if it exists.
12056 Reported by Ezra Peisach.
12058 2001-11-03 Akim Demaille <akim@epita.fr>
12060 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
12061 passed on command line, defaulting to ./configure.ac if present.
12062 (&maybe_autoreconf, File::Find): Remove, unused.
12063 (&autoreconf): If autoconf is not used, don't try to trace.
12065 2001-11-02 Akim Demaille <akim@epita.fr>
12067 * configure.ac: Bump to 2.52g.
12069 2001-11-02 Akim Demaille <akim@epita.fr>
12071 Version 2.52f.
12073 2001-11-02 Akim Demaille <akim@epita.fr>
12075 * config/config.guess, config/config.sub, doc/standards.texi:
12076 * config/lispdir.m4: Update from masters.
12077 * configure.ac: Bump to 2.52f.
12079 2001-11-02 Akim Demaille <akim@epita.fr>
12081 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
12082 Don't run aclocal when aclocal.m4 is not from aclocal.
12083 From Ezra Peisach.
12084 Don't run libtoolize and gettextize if --install is not given.
12086 2001-11-01 Paul Eggert <eggert@twinsun.com>
12088 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
12089 be invoked before _AS_LINENO_PREPARE.
12090 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
12091 than character ranges.
12093 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
12094 invoking AS_BASENAME. Set the locale variables to 'C' if
12095 possible, as POSIX requires this to get the traditional
12096 behavior.
12097 * doc/autoconf.texi (Special Shell Variables): Describe the above.
12099 2001-10-31 Paul Eggert <eggert@twinsun.com>
12101 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
12102 with {}, as that triggers a bug in Bash 2.05.
12104 (_AS_LINENO_PREPARE): Use Sed rather than
12105 Awk. Fix the sed prepass to work even if there are multiple
12106 instances of $LINENO on the same line. Do not substitute for
12107 other variables like $LINENOT. Do not check file dates; such a
12108 check is unreliable on sufficiently fast machines, and removing
12109 the check makes the code simpler and more reliable. Check for
12110 output and chmod failures.
12112 * doc/autoconf.texi (Special Shell Variables): Document
12113 the above.
12115 2001-10-31 Akim Demaille <akim@epita.fr>
12117 * tests/Makefile.am (atconfig): Remove this target, Automake
12118 handles it now.
12120 2001-10-31 Akim Demaille <akim@epita.fr>
12122 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
12123 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
12124 provided, while it is optional.
12125 * configure.ac: Adjust.
12127 2001-10-26 Paul Eggert <eggert@twinsun.com>
12129 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
12130 lib/Autom4te/Struct.pm:
12131 Require Perl 5.005_03 instead of just 5.005, as some tests fail
12132 with 5.005_02.
12134 * doc/autoconf.texi (Special Shell Variables): Document some
12135 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
12137 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
12138 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
12139 eval $LINENO is not portable in practice.
12141 2001-10-24 Akim Demaille <akim@epita.fr>
12143 * lib/Autom4te/General.pm (backname): New.
12145 2001-10-24 Akim Demaille <akim@epita.fr>
12147 * m4/: Remove, merged into...
12148 * config/: here.
12150 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
12152 * doc/autoconf.texi (Shellology): Mention the problems with bash
12153 2.05's use of ANSI quoting in its `set' builtin.
12155 2001-10-22 Paul Eggert <eggert@twinsun.com>
12157 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
12158 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
12159 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
12160 POSIX decided to standardize on the int flavor of strerror_r.
12161 Always do char* test, as there's no reason not to.
12162 Assign to a char* var, to catch strerror_r that returns int*.
12164 * doc/autoconf.texi (Particular Functions):
12165 Document the above changes. Also, document the fact that
12166 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
12168 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
12170 2001-10-20 Akim Demaille <akim@epita.fr>
12172 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
12173 the executable was missing from the log.

12177 * lib/Autom4te/General.pm (&update_file): If destination is
12178 unchanged, remove the source.
12179 (&up_to_date_p): Don't be verbose, be debug.
12180 * bin/autoreconf.in: No longer support --m4dir.
12181 (&autoreconf): Display the full path of the configure.ac we are
12182 studying.
12183 Trace it only once.
12184 Be sure to honor --force with gettextize.
12185 Always run aclocal.
12186 * doc/autoconf.texi: Adjust.
12188 2001-10-20 Akim Demaille <akim@epita.fr>
12190 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
12191 Remove, dead.
12192 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
12193 `intl' is already present, as it refuses unless --force.
12194 (&parse_args): Use -I, --include instead of the old Autoconf
12195 options.
12196 ($localdir, $autoconf_dir): Remove.
12197 (@include): New.
12198 (&maybe_autoreconf): New, to preserve $_ for File::Find.
12200 2001-10-19 Jens Petersen <petersen@redhat.com>

12208 file in @configure_input@.
12209 Don't mention `automatically' in addition to `generated'.
12210 * tests/torture.at (#define header templates): Adjust.
12212 2001-10-19 Akim Demaille <akim@epita.fr>
12214 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
12215 comment, explain how to install automatic mode selection.
12216 From Russ Allbery.
12218 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
12220 * bin/autoreconf.in (autoreconf): Display the path to the
12221 configure.ac being studied.
12223 2001-10-18 Paul Eggert <eggert@twinsun.com>
12225 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
12226 long, to work around a bug in the HP C compiler version HP92453-01
12227 B.11.11.23709.GP.
12229 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
12230 (AS_BASENAME_EXPR): New macro.
12231 (AS_BASENAME_SED): Do not assume GNU sed semantics.
12232 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
12233 and fall back on 'sed' only if the other two fail. This makes
12234 AS_BASENAME act more like AS_DIRNAME.
12235 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
12236 contains white space.
12237 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
12238 Use AS_DIRNAME, since I think it's now DOS-friendly.
12239 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
12240 Allow "dirname //FOO" to return either / or //, as POSIX allows
12241 either behavior.
12243 2001-10-10 Akim Demaille <akim@epita.fr>
12245 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
12246 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
12247 From Eric Sharkey.
12249 2001-10-10 Akim Demaille <akim@epita.fr>
12251 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
12252 m4_define, since...

12291 bother with $force since...
12292 * lib/Autom4te/General.pm: does.
12294 2001-10-08 Akim Demaille <akim@epita.fr>
12296 * bin/autoreconf.in: Rewrite in Perl.
12297 * configure.ac: Adjust.

12348 Use `add-log-current-defun-function' for ChangeLog creation.

12370 * tests/tools.at (AT_DATA_FORBIDDEN): New.

12381 empty, and if we can find a shell that does support LINENO,
12382 then set CONFIG_SHELL to that shell and then re-execute
12383 ourselves with CONFIG_SHELL.
12385 2001-10-05 Paul Eggert <eggert@twinsun.com>
12387 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

12391 2001-10-05 Akim Demaille <akim@epita.fr>
12393 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

12458 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
12459 Don't use nested parenthesization. This patch was originally
12460 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
12461 but somehow it didn't get incorporated then.
12462 * doc/autoconf.texi (Limitations of Usual Tools):
12463 Clarify remark about sed and nested parenthesization.
12465 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
12466 Report an error if the size cannot be determined even though
12467 the type exists.
12468 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
12469 Check for `expr' arithmetic overflow, and for compilation failure,
12470 and invoke a new argument $4 if either is discovered.
12471 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
12472 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
12474 2001-09-28 Akim Demaille <akim@epita.fr>

12494 status when executing the ACTION-IF-FALSE.

12514 Raja R Harinath:

12568 * doc/autoconf.texi (Common Shell Constructs): Rename as...

12613 * tests/Makefile.am (package.m4): Remove.
12615 2001-09-22 Akim Demaille <akim@epita.fr>
12617 Rely on `$LINENO' when possible instead of `__oline__'.
12619 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
12620 `$LINENO' support replacement when not supported.
12621 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
12622 them explicitly to be sure they are not output before this section

12632 character (u: -> ue) in a code comment.
12633 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
12634 it works.
12636 2001-09-21 Akim Demaille <akim@epita.fr>
12638 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
12639 Suggested by Jim Meyering.
12641 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12643 * lib/autoconf/programs.m4: Use extensions listed in
12644 $ac_executable_extensions when looking for programs.

12648 * lib/autoconf/general.m4: Fix a small Englisho.

12656 PATH_SEPARATOR.
12657 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

12663 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12665 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
12666 arguments. Fixed a typo.
12668 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12670 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
12671 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
12673 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12675 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
12676 * bin/autoupdate.in: Ditto.
12677 * bin/autoheader.in: Reworded a few comments.
12678 * bin/autoconf.in: Reworded help text for a few options.

12682 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12684 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
12685 already have $file). Set output files to binary mode (helps avoid
12686 CR issues on DOSish systems).
12688 2001-09-19 Akim Demaille <akim@epita.fr>
12690 * lib/autotest/general.m4: Englishoes.
12691 From Tim Van Holder and Alexey Mahotkin.
12693 2001-09-18 Paul Eggert <eggert@twinsun.com>
12695 * doc/autoconf.texi (Common Shell Constructs): New node,
12696 documenting AS_DIRNAME.
12697 (Limitations of Usual Tools): Refer to it when discussing dirname.
12698 Also, update discussion of POSIX standard to reflect latest draft.
12700 * lib/autoconf/c.m4:
12701 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
12703 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
12704 Do not pass a first argument with leading '-'
12705 to expr, by parenthesizing initial integers that might be negative.
12707 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
12708 now merely checks whether it is an error to pass an argument
12709 to getpgrp.
12711 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
12712 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
12713 whether it is a (compile-time) error to pass an argument to
12714 getpgrp. This simpler test supports the revised documentation,
12715 and is all that AC_FUNC_GETPGRP's users really need.
12717 2001-09-18 Akim Demaille <akim@epita.fr>
12719 * doc/autoconf.texi (Limitations of Make) <$<>: New.
12721 2001-09-18 Akim Demaille <akim@epita.fr>

12727 2001-09-18 Paul Wagland <paul@wagland.net>
12729 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
12730 correctly.
12731 Add test for AS_BASENAME.
12732 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
12733 added test. It now correctly handles /1/2/3/, returning '3' not ''.
12734 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
12735 * tests/base.at: Fixed the expected responses. The old ones were
12736 one line out...
12737 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
12738 the documentation claims it should (and how it behaved in 2.13).
12740 2001-09-18 Akim Demaille <akim@epita.fr>
12742 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
12743 the AC_CONFIG_COMMANDS invocation.
12744 This also solves the name clash problems.
12745 Don't set the package's ID.
12746 * lib/m4sugar/Makefile.am (version.m4): Revamp.
12747 No longer to be shipped.
12748 (version.in): Remove.
12749 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
12750 * lib/autoconf/status.m4: Adjust.
12751 Use `m4_PACKAGE_STRING'.
12752 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
12753 the only optional argument is the name of the test suite.
12754 Expect `package.m4' to define the package signature.
12755 * lib/autom4te.in (Autotest): Add `package.m4?'.
12756 * tests/Makefile.am (package.m4): New.
12757 * tests/suite.at: ifnames is a victim.
12759 2001-09-18 Akim Demaille <akim@epita.fr>
12761 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
12762 AC_LIBSOURCE, AC_CONFIG_FILES.
12763 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
12764 program version string doesn't match the package's.
12765 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
12766 after `(cached)'.

12770 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12771 Allow expression to return any value that can fit into unsigned long
12772 (not int, as before). Check for output errors.
12774 2001-09-17 Bruno Haible <haible@ilog.fr>
12776 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12777 Always include <stdio.h> and <stdlib.h>. Evaluate
12778 the expression in an extra function before these includes. Call
12779 fprintf "%d" only after ensuring the argument is of type 'int'.
12780 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
12782 2001-09-17 Paul Eggert <eggert@twinsun.com>
12784 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
12785 or CFLAGS=-O5. In that case, the linker has a relaxed view of
12786 fatal errors, and AC_CHECK_LIB causes it to include libraries even
12787 when they don't exist.
12789 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
12790 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
12791 need it.
12793 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
12794 version with the version used by fileutils 4.1, except use
12795 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
12796 we don't need it.
12798 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
12800 2001-09-13 Akim Demaille <akim@epita.fr>
12802 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
12803 _first_.
12804 Reported by Gerrit P. Haase.
12806 2001-09-13 Akim Demaille <akim@epita.fr>
12808 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
12809 m4_defn'ing is valid.

12823 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
12824 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
12825 Likewise.

12827 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
12828 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
12829 AT_tests_all for consistency.
12830 Set at_victims.
12831 (AT_VICTIMS): Similar to AT_KEYWORDS.
12832 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
12834 2001-09-13 Akim Demaille <akim@epita.fr>
12836 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
12838 2001-09-13 Akim Demaille <akim@epita.fr>
12840 * lib/autotest/general.m4 (AT_INIT): Create and remove
12841 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
12842 test suites can cohabit.
12844 2001-09-13 Akim Demaille <akim@epita.fr>
12846 * tests/mktests.sh: Don't output banners for empty test files.
12848 2001-09-13 Akim Demaille <akim@epita.fr>
12850 Test suites can be run independently of configure.

12865 (Syntax of the shell scripts): Don't check ifnames.
12866 (AT_CHECK_PERL_SYNTAX): New.

12892 (m4_list_append): Remove.
12894 Spread a few keywords in the Autoconf test suite.
12896 2001-09-10 Akim Demaille <akim@epita.fr>
12898 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

12917 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
12918 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package

12931 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
12932 in addition, it introduces useless differences in logs.
12933 (AT_INIT): Let atconfig and atlocal be both optional.
12934 Adjust PATH computation.
12935 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.
12937 2001-09-07 Akim Demaille <akim@epita.fr>
12939 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon
12940 m4sugar/version.m4.
12942 2001-09-05 Akim Demaille <akim@epita.fr>
12944 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'

12946 From Uwe Seimet.
12948 2001-09-05 Akim Demaille <akim@epita.fr>
12950 * bin/autom4te.in: --language is -l, not -s.
12952 2001-09-05 Akim Demaille <akim@epita.fr>
12954 Be ready to handle filenames as stupid as `dnl.at', for if even
12955 the maintainer is dumb enough to do that...
12957 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
12958 excellence in M4 quotation: consider `__file__' is active.
12960 And BTW, when invoking m4, pass the --include in the right order:
12961 the wrong one.
12963 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
12964 4m.
12966 2001-09-05 Akim Demaille <akim@epita.fr>
12968 * lib/Autom4te/XFile.pm: New lib file.
12969 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
12970 * bin/autoheader.in: Use it.
12972 2001-09-05 Akim Demaille <akim@epita.fr>
12974 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff
12975 defined.

12982 * bin/autoscan.in: Use `getopt' and `find_files' etc.
12983 Add -I, --include support.
12984 * doc/autoconf.texi (autoscan Invocation): Adjust.
12986 2001-09-05 Akim Demaille <akim@epita.fr>
12988 CVS GNU M4 doesn't like `undefine(undefined)'.
12990 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
12991 New, extracted from main.
12992 Use IO::File wherever possible.
12993 (input.m4): Be constant, use -I instead of hard coding $tmp.
12994 Therefore be a quoted heredoc.
12995 Don't invoke `_au_disable', since ac was not loaded, but just
12996 `unm4.m4'.
12998 2001-08-31 Akim Demaille <akim@epita.fr>
13000 Version 2.52d.
13002 2001-08-31 Akim Demaille <akim@epita.fr>
13004 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
13005 previous patch.
13006 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
13008 2001-08-31 Akim Demaille <akim@epita.fr>
13010 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
13011 serious problems handling heredocs in heredocs.
13012 Reported by Nicolas Joly.
13014 2001-08-31 Akim Demaille <akim@epita.fr>
13016 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
13017 (Making testsuite Scripts): Update.
13019 2001-08-31 Akim Demaille <akim@epita.fr>
13021 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
13023 2001-08-31 Akim Demaille <akim@epita.fr>
13025 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
13026 (testsuite Scripts): There is no such thing as `atconfig.in'.
13027 And actually one diagram is missing: test suite runtime.
13029 2001-08-31 Akim Demaille <akim@epita.fr>
13031 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
13032 inverse order.
13034 2001-08-31 Akim Demaille <akim@epita.fr>
13036 * bin/autoupdate.in (@include): `installcheck' revealed the path
13037 to m4sugar was lacking!
13039 2001-08-31 Akim Demaille <akim@epita.fr>
13041 * man/Makefile.am (.x.1): We really have to pass
13042 autom4te_perllibdir.
13044 2001-08-31 Akim Demaille <akim@epita.fr>
13046 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
13047 debug scripts, in particular passing explicitly listed tests to
13048 run is stupid.
13050 2001-08-31 Akim Demaille <akim@epita.fr>
13052 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
13053 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
13054 Use directly autom4te, not autoconf.
13055 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
13057 2001-08-31 Akim Demaille <akim@epita.fr>
13059 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
13060 * bin/autoheader.in (%symbol): Strip arguments of macros.

13066 2001-08-31 Akim Demaille <akim@epita.fr>
13068 * bin/autom4te.in (&parse_args): Die on unknown languages.
13069 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
13070 need for autoconf.
13071 Promote --include over --macrodir and other obsolete options.
13073 2001-08-31 Akim Demaille <akim@epita.fr>
13075 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
13076 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
13077 * bin/autom4te.in ($autoconf): Pass --force.
13078 `print $out' doesn't print `$_' but `$out'.
13079 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
13080 (autoheader): Pass --force since the test suite goes too fast for
13081 the time stamps.
13082 Adjust to the new autoheader messages.
13084 2001-08-31 Akim Demaille <akim@epita.fr>
13086 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
13087 Check the completeness of the #template.
13088 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
13089 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
13090 invocation.
13092 2001-08-31 Akim Demaille <akim@epita.fr>
13094 * lib/Autom4te/General.pm (&find_file, &update_file): New.
13095 * bin/autoupdate.in, bin/autoheader.in: Adjust.
13096 Drop AC_MACRODIR dead for real.
13097 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
13098 `autoheader: `config.hin' is created'.
13099 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
13101 2001-08-31 Akim Demaille <akim@epita.fr>
13103 * bin/autoheader.in: Rewrite in Perl.
13104 * tests/autoheader: Adjust.
13106 2001-08-31 Akim Demaille <akim@epita.fr>
13108 * bin/autoconf.in (--include, -I): New option.
13109 Map --localdir, --autoconf-dir onto it.
13110 Forward autom4te's options instead of interpreting them.
13111 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
13112 There is no such envvar since the inception of autom4te.cfg.
13113 * bin/autom4te.in (&parse_args): Uniquify `@include'.
13114 * bin/autoupdate.in: Adjust, and perform more control.
13115 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
13116 * tests/autoconf: Dittowise.
13118 2001-08-31 Akim Demaille <akim@epita.fr>
13120 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
13121 * bin/autom4te.in (&find_file): Support `FILE?' standing for
13122 optionally `FILE'.
13123 Use -e, not -f, since /dev/null for instance is OK.
13124 (&parse_args): Adjust.
13125 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
13127 2001-08-31 Akim Demaille <akim@epita.fr>
13129 * configure.ac: Also find tested executables in bin.
13130 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
13131 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
13132 installed peer executables, only PATH is allowed to resolve it.
13133 Pass `autoconf_dir' via options, not via invisible envvars.
13134 * lib/Autom4te/General.pm (&find_peer): Remove.
13135 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
13136 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
13137 * man/Makefile.am: Let help2man rely on PATH instead of trying to
13138 find the executables for it.
13139 * tests/Makefile.am: Major cleanup. Too lazy to document...
13140 * tests/atlocal.in: Remove all the obscure envvar manipulations.
13141 We only need PERL.
13142 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
13143 indeed related to running the test suite, while passing
13144 --autoconf-dir and others is related to running non installed
13145 Autoconf executables. So don't do that, leave it to...
13146 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
13147 * tests/autoscan: New.
13148 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
13149 refer to library files: rely on --language.
13151 2001-08-29 Akim Demaille <akim@epita.fr>
13153 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
13154 s/--set/--language/.
13156 2001-08-29 Akim Demaille <akim@epita.fr>
13158 * doc/autoconf.texi: Strip the @nodes.
13159 Suggested by Paul Eggert.
13160 (Initializing configure): Typo.
13162 2001-08-29 Akim Demaille <akim@epita.fr>
13164 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
13165 Suggested by Paul Eggert.
13167 2001-08-29 Akim Demaille <akim@epita.fr>
13169 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
13170 download in a tmp dir.
13172 2001-08-29 Akim Demaille <akim@epita.fr>
13174 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
13175 case insensitive OSes out there :(
13176 From Tim Van Holder.
13178 2001-08-29 Akim Demaille <akim@epita.fr>
13180 * lib/autom4te.in: New.
13181 * lib/Makefile.am (edit, autom4te.cfg): New.
13182 * bin/autom4te.in (BEGIN): Simplify.
13183 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
13184 (&load_configuration): New. Use it.
13185 (&parse_args): Support --mode, --set, and --melt.
13186 * bin/autoconf.in: Simplify and adjust.
13187 * tests/Makefile.am (AUTOMAKE): Use --set.
13188 * tests/atlocal.in: Adjust.
13189 * BUGS: distcheck and check are weak.
13191 2001-08-29 Akim Demaille <akim@epita.fr>
13193 * lib/autotest/general.m4: Use
13194 foo=`(command) 2>/dev/null`
13195 not
13196 foo=`command` 2>/dev/null
13197 (at-devnull): Rename as...
13198 (AT-devnull): this.
13199 (--clean): Remove AT-* files too.
13200 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
13201 Reported by Nicolas Joly.
13203 2001-08-28 Akim Demaille <akim@epita.fr>
13205 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
13206 quotes inside single quotes.
13207 Reported by Nicolas Joly.
13209 2001-08-28 Kevin Ryde <user42@zip.com.au>
13211 * doc/autoconf.texi (Function Portability): Mention C right shifts.
13213 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
13215 * lib/autotest/general.m4: Reword some messages.
13216 (AT_INIT): Check for the `times' builtin before using it.
13217 Support test ranges as arguments to the testsuite.
13218 Have -e imply -d as the help text suggested.
13220 2001-08-27 Akim Demaille <akim@epita.fr>
13222 * Makefile.maint: Formatting changes.
13223 (do-po-update, po-update, cvs-update, update): New targets.
13224 (AMTAR): Remove.
13226 2001-08-27 Akim Demaille <akim@epita.fr>
13228 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

13233 2001-08-27 Akim Demaille <akim@epita.fr>
13235 * lib/autotest/general.m4 (AT_INIT): Log the command line.
13236 Support `VAR=VAL' as arguments.
13237 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
13238 may be set via the command line.
13240 2001-08-27 Akim Demaille <akim@epita.fr>
13242 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
13243 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
13244 first the build dirs, then the src dirs.
13245 * configure.ac (AC_CONFIG_TESTDIR): Adjust.
13247 2001-08-27 Akim Demaille <akim@epita.fr>
13249 * lib/autotest/general.m4 (AT_INIT): Output the definition of

13254 2001-08-27 Akim Demaille <akim@epita.fr>
13256 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
13257 `ac_top_builddir' to mimic Automake's vocabulary, which much more
13258 readable.
13259 Adjust callers.
13260 * doc/autoconf.texi (Configuration Actions): Document the vars
13261 available in commands.
13262 Emphasize the risks of collisions in init-cmds.
13264 2001-08-27 Akim Demaille <akim@epita.fr>
13266 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
13267 (Initializing configure): this new node.
13269 2001-08-27 Akim Demaille <akim@epita.fr>

13282 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move
13283 to...
13284 * lib/autoconf/autoheader.m4: this new file.
13285 * lib/autoconf/general.m4 (AH_OUTPUT, AH_VERBATIM)

13290 2001-08-27 Akim Demaille <akim@epita.fr>
13292 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
13293 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
13294 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
13295 -> ac_dir).
13296 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
13297 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
13299 2001-08-27 Akim Demaille <akim@epita.fr>

13324 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
13325 (AMTAR): Help automake define it.
13326 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
13327 needed, 1.5 can have a macro and a target with the same name.
13328 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
13329 * m4/strip.m4: New.

13342 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
13343 Adjust callers.
13344 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
13345 the name of the directory they're in, instead of the filename,
13346 since version.m4 is now in m4sugar, but m4_acversion must not be
13347 classified as an Autoconf macro.
13348 ($input_m4): Don't qualify the path to m4sugar.
13349 Rather, pass autoconf_dir to m4.
13350 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
13351 * tests/suite.at: Require 2.52c.
13353 2001-08-27 Akim Demaille <akim@epita.fr>

13365 of config.log on traps.
13366 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
13367 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
13368 for config.status'.
13369 Open the log as soon as possible.
13370 Use the same log introduction as configure's.
13372 2001-08-22 Paul Eggert <eggert@twinsun.com>
13374 * doc/autoconf.texi (Indices): New node.
13375 Move indices out of the top level menu and into this submenu.
13377 2001-08-22 Akim Demaille <akim@epita.fr>
13379 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13380 AC_TRY_COMMAND.

13434 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
13435 * NEWS, README, README-alpha, TODO, tests/README: This package is
13436 `Autoconf', not `autoconf' (the executable).
13438 2001-08-20 Akim Demaille <akim@epita.fr>
13440 Info readers seem to need `Index' in the index node title :(
13442 * doc/autoconf.texi: Reverse the 2001-08-15 change which
13443 simplified index node names.

13487 2001-08-20 Akim Demaille <akim@epita.fr>
13489 Huh!?!?! There are still some user EOF tags used, which prevents
13490 their use in AC_CONFIG_COMMANDS for instance...
13492 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
13493 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

13554 2001-08-17 Akim Demaille <akim@epita.fr>
13556 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
13557 `$0.log' as for projects where testsuite is in src, we'd have
13558 testsuite.log created in src.

13562 * bin/autom4te.in (&parse_args): Recognize --normalize.

13572 2001-08-17 Akim Demaille <akim@epita.fr>
13574 * doc/autoconf.texi: Work around Texinfo buglets.
13575 (Transformation Rules): One example is enough, users are expected
13576 to have their brains on. And BTW, use DESTDIR.
13577 (dvar): New macro. Use it.
13579 2001-08-17 Akim Demaille <akim@epita.fr>
13581 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

13587 * bin/autom4te.in: --normalize is a new option.
13588 * bin/autoconf.in: Use it.

13600 2001-08-15 Akim Demaille <akim@epita.fr>
13602 * doc/Makefile.am (fu): New index, can't use fn because of defmac.
13603 Use it.
13605 2001-08-15 Akim Demaille <akim@epita.fr>

13614 * doc/install.texi: Use @command.

13616 (Defining Variables): this.
13618 2001-08-15 Akim Demaille <akim@epita.fr>
13620 * doc/autoconf.texi (Function Portability): sprintf's return
13621 value.
13622 From Kevin Ryde.
13624 2001-08-15 Akim Demaille <akim@epita.fr>
13626 * Makefile.maint (CVS): New.
13627 (local-check): Run changelog-check. last.
13628 (alpha): Don't depend upon local-check, since...
13629 (cvs-dist): depends upon it.
13631 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
13633 * tests/Makefile.am: Use a clean-local rule to remove
13634 autom4te.cache (it's a directory, not a file.
13635 * Makefile.am: Ditto (but maintainer-clean-local).
13637 2001-08-15 Akim Demaille <akim@epita.fr>
13639 * bin/autom4te.in (@m4_warning): New.
13640 (&handle_m4): Use it.
13641 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
13642 warnings are issued at each run.
13643 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
13644 is in the src tree.
13646 2001-08-15 Akim Demaille <akim@epita.fr>
13648 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
13649 don't waste time running `autoupdate --version' works.
13650 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
13652 2001-08-13 Akim Demaille <akim@epita.fr>
13654 * doc/autoconf.texi (ma): Rename this index as...
13655 (ac): this.

13667 * lib/autotest/general.m4 (AT_INIT): Log the start/stop dates and
13668 duration of the test suite.
13670 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
13672 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
13673 endianness for comparison instead of relying on AT_CHECK_ENV.
13675 2001-08-11 Paul Eggert <eggert@twinsun.com>
13677 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
13678 to the INSTALL file.
13680 2001-08-11 Paul Eggert <eggert@twinsun.com>

13705 * tests/mktests.sh: Update year in copyright notice.
13707 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
13709 * tests/semantics.at (AC_C_BIGENDIAN): New test.
13711 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13713 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
13714 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
13715 * doc/autoconf.texi (C Compiler Characteristics): Update
13716 documentation for AC_C_BIGENDIAN.
13718 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13720 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
13721 magic values from an object file when cross-compiling.
13722 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
13724 2001-08-10 Akim Demaille <akim@epita.fr>
13726 * bin/autom4te.in (&handle_output): Don't use `grep' with side
13727 effects.
13728 Suggested by Russ Allbery.
13730 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
13732 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
13733 current $prefix to the sub-configures.
13735 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
13737 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
13738 extension (needed on BeOS). Reported by Guido van Rossum.
13740 2001-08-09 Akim Demaille <akim@epita.fr>
13742 * bin/autom4te.in ($icache): Load it only if older than autom4te.
13744 2001-08-07 Akim Demaille <akim@epita.fr>
13746 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
13747 removed.
13748 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
13749 No need to remove the files before and after the each test, before
13750 each test and at the end of the suite is enough.
13751 Display only the children `times', not the shell's.
13752 If the test failed or was skipped, at-times is not available.
13754 2001-08-07 Akim Demaille <akim@epita.fr>
13756 Always produce testsuite.log, including when there are no
13757 failures. This helps getting information on skipped tests, and
13758 duration of the tests. Err, implement the latter btw.
13760 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
13761 Dump information on the first run of each test.
13762 (AT_CLEANUP): Create `at-times' containing the duration of the
13763 test group.
13765 2001-08-07 Akim Demaille <akim@epita.fr>
13767 The use of `dumpstat' revealed that `len' was used although it
13768 should not. m4_text_wrap was using it, but in the Autoconf world
13769 where it is legal. Hence (i) test M4sh in its own world, not
13770 Autoconf's, and (ii), ahem, fix the bug :)
13772 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
13773 does not like `' instead of [].
13774 (AT_INIT): Forbid `^_?AT_'.
13775 And don't output such tokens.
13776 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
13777 `script.as', and `autom4te.cache'.
13778 Remove `empty' and `macro' which are no longer used.
13779 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
13780 * tests/m4sugar.at: Use it.
13781 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
13783 2001-08-07 Akim Demaille <akim@epita.fr>
13785 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
13787 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
13789 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
13791 2001-08-04 Akim Demaille <akim@epita.fr>
13793 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
13794 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
13795 AC_TRY_LINK.
13796 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
13797 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
13798 (AC_F77_MAIN): Likewise.
13800 2001-08-04 Akim Demaille <akim@epita.fr>
13802 Don't rely on M4sugar outputting the patterns in files, since we
13803 might process the output _without_ running m4, hence without these
13804 files.
13806 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
13807 * bin/autom4te.in (@Request::includes): Remove, unused.
13808 (@Request::source): Rename as...
13809 (@Request::input): this.
13810 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
13811 (&handle_output): Fetch the patterns from the traces.
13812 `$forbidden' and `$allowed' are constant: use m//o.
13813 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
13814 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
13816 2001-08-04 Akim Demaille <akim@epita.fr>
13818 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
13819 autoconf', i.e., in addition to caching traces, cache the output.
13821 * bin/autom4te.in (Request::cache): Rename as...
13822 (Request::id): this.
13823 ($cache, $icache, $tcache, $ocache): New.
13824 (&handle_m4): Save M4 output in the cache instead of $tmp.
13825 (&handle_output): Adjust.
13826 (&up_to_date_p): Check that the output cache is up to date too.
13827 (top level): Run `&handle_m4' iff force or the cache is invalid.
13828 Run `&handle_output' if the output cache is more recent.

14371 cross-language link tests can be performed successfully.
