4 Jim Meyering.
6 2006-10-25 Stepan Kasal <kasal@ucw.cz>
8 * tests/tools.at (autom4te --force): New test, verifies that
9 `--force' always rewrites the output file.
11 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
13 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm
14 needs operands on NetBSD 2.0.2. Problem reported by Bruno Haible.
16 2006-10-24 Stepan Kasal <kasal@ucw.cz>
18 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
20 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
22 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
23 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
24 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
25 reported by Nelson H. F. Beebe for Coreutils 6.4.
27 * tests/tools.at (autoconf --trace: user macros): Remove test
28 for tracing multiline macros, since m4 1.4.7a uses a different
29 way to number lines. Problem reported by Ralf Wildenhues.
31 2006-10-24 Stepan Kasal <kasal@ucw.cz>
33 * bin/autom4te.in (handle_m4): Do not redirect stdin to
34 /dev/null since the heuristics for interactive behaviour was
35 fixed in CVS m4.
37 * bin/autom4te.in: With --force, always refresh the output
38 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
40 * bin/autoconf.as: Fix the verbose message at the end.
42 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

52 2006-10-15 Karl Berry <karl@gnu.org>
53 * build-aux/texinfo.tex: automake 1.10
55 * NEWS: Remove AC_CACHE_CHECK_INT.
56 * doc/autoconf.texi (Caching Results): Likewise.
57 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
58 AC_CACHE_CHECK_INT, since it's no longer public.
59 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
60 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
62 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
64 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
66 2006-10-19 Eric Blake <ebb9@byu.net>
68 * lib/m4sugar/m4sugar.m4 (m4_mkstemp): New macro.
69 (m4_maketemp): Avoid warnings with M4 1.9a.
70 * lib/emacs/autoconf-mode.el (autoconf-font-lock-keywords): Color
71 m4_mkstemp.
72 * doc/autoconf.texi (Redefined M4 Macros): Document m4_mkstemp.
73 * NEWS: Likewise.
75 2006-10-16 Eric Blake <ebb9@byu.net>
77 * doc/autoconf.texi (Setting Output Variables): Fix typo.

80 Standards.
81 * bin/autoheader.in (version): Likewise.

84 * bin/autoscan.in (version): Likewise.
85 * bin/autoupdate.in (version): Likewise.
86 * bin/ifnames.in (version): Likewise.
88 2006-10-14 Stepan Kasal <kasal@ucw.cz>
90 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
91 looking for special shell characters.
92 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
93 macro defined by AS_VAR_PUSHDEF before passing it as a
94 parameter.
95 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
96 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):
97 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW, AC_CHECK_MEMBER):
98 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL):
99 (_AC_CHECK_HEADER_NEW, _AC_CHECK_HEADER_OLD, _AC_CHECK_HEADER_DIRENT):
100 Likewise.
101 * lib/autotest/general.m4 (AT_INIT): Quote parameters of
102 AS_VAR_* properly.
103 * tests/m4sh.at (AS_LITERAL_IF): New test.
105 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
107 (Imported from Automake.)
108 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
109 which incorrectly sets the mode of an existing destination
110 directory. In some cases the unpatched install-sh could do the
111 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
112 system. We hope this is rare in practice, but it's clearly worth
113 fixing. Problem reported by Alex Unleashed in
114 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
115 Also, don't bother to check for -m bugs unless we're using -m;
116 suggested by Stepan Kasal.
118 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
120 Import this change from Automake:
122 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
123 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
124 is enabled by default with gnu and gnits strictness.
125 Report from Bruno Haible.
127 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
128 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
129 gnu and gnits modes.
131 Import this change from Config:
133 2006-09-20 Ben Elliston <bje@gnu.org>
134 * build-aux/config.sub (score, score-*): New.
136 Import this change from Gnulib:
138 2006-09-16 Karl Berry <karl@gnu.org>
139 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
140 to avoid sectioning errors.
142 Import these changes from Texinfo:
144 2006-10-04 Karl Berry <karl@gnu.org>
145 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
146 (\quoteexpand): rename to \rquoteexpand.
147 (\codequoteleft): new def, to look for @set codequotebacktick.
148 (\lquoteexpand, \quoteexpand): new defs.
149 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
150 (\code): must use new \...Char values, since now ` is active.
152 2006-08-26 Karl Berry <karl@gnu.org>
153 * build-aux/texinfo.tex (\textdegree): New command.
155 2006-08-12 Karl Berry <karl@gnu.org>
156 * build-aux/texinfo.tex (error \box0): smaller font.
158 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
160 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
162 2006-10-13 Stepan Kasal <kasal@ucw.cz>
164 * doc/autoconf.texi (Autoheader Macros): Warn that the text
165 added to the template can get mangled.
167 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
169 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
170 include the default headers, and redefine obstack_chunk_alloc
171 and obstack_chunk_free. Fixes false failure with glibc.
173 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
175 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
176 for backward compatibility with Libtool 1.5.22. Problem reported
177 by Ralf Wildenhues.
179 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
181 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
182 AC_PROG_CC.
183 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
185 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
187 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
188 the NonStop platform.
189 * doc/autoconf.texi (Posix Variants): Likewise.
190 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
192 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
193 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
194 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
195 Use a better substitute, by inspecting the output of "ls"
196 rather than just using ":".
197 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
198 rather than AS_EXECUTABLE_P, since we needn't worry about
199 non-regular files here.
201 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
202 due to configuration hassles with this. See Tonya Underwood's report
203 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
204 * doc/autoconf.texi (Special Shell Variables): Likewise.
206 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
207 Stepan Kasal <kasal@ucw.cz>
209 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
210 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
212 2006-10-11 Stepan Kasal <kasal@ucw.cz>
214 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
215 initialization which is not inherited through the environment
216 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
217 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
219 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
221 * doc/autoconf.texi (Limitations of Usual Tools): Describe
222 problems with mkdir -p -m.
224 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
226 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
227 comment about ac_cpp_err; it was incorrect, and anyway
228 ac_cpp_err is being removed below.
229 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
230 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
231 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
232 nobody uses it.
233 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
234 with werror_flag and conftest.err and so forth. This is more
235 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
236 and anyway the user shouldn't normally want to see this gorp logged.
237 Problem reported by Ralf Wildenhues.
238 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
239 empty, not 'no', since the rest of the code uses 'test -z'.
241 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
243 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
244 Use a single call to AC_DO_TOKENS rather than multiple, for
245 efficiency.
246 (_AC_LINK_IFELSE): Test that resulting file is executable.
247 Problem reported by mwoehlke in
248 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
250 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
251 than creating a file to use with test -x; this is much faster.
253 2006-10-02 Bruno Haible <bruno@clisp.org>
255 * lib/autom4te.in (Automake-preselections): Add
256 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
258 2006-09-27 Stepan Kasal <kasal@ucw.cz>
260 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
261 standard error, `experr' should be used, not `expout'.
263 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
265 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
266 fseeko testing program twice; just use the earlier result.
267 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
268 Set cache var to 'unknown' (not 'no') if leaving the macro unset
269 still doesn't let the program compile.
270 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
271 failed.
273 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
274 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
275 include it, without including anything else.
276 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
277 expressions.
278 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
280 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
282 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
283 `error.h', and include it, for a `error_at_line' prototype.
284 Use a nonempty format string in the link test.
285 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
286 for a declaration of wait3.
288 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
290 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
291 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
292 can apply to constants too, and that it checks for macro defns.
293 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
294 and simply cast the identifier to void. This handles structure
295 values. Problem reported by Ralf Wildenhues.
296 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
298 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
300 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
301 structure, and function symbols.
303 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
305 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
306 member.
308 2006-09-25 Paul Eggert <eggert@cs.ucla.edu>

314 2006-09-25 Paul Eggert <eggert@cs.ucla.edu>
315 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
317 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): Avoid `gcc -Wall'
318 warnings (uninitialized value).
319 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
320 present.
321 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add
322 parentheses.
323 (AC_STRUCT_TM): Likewise, avoid unused variables.

348 * tests/Makefile.in: Likewise.
350 * m4/m4.m4 (AC_PROG_GNU_M4): Check for m4 --debugfile support.
351 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
352 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
353 --error-output, to avoid warnings with M4 2.0.
355 2006-09-19 Stepan Kasal <kasal@ucw.cz>
357 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be
358 consistent with _AH_CHECK_FUNCS and _AH_CHECK_HEADERS.
359 * lib/autoconf/headers.m4 (AH_CHECK_HEADERS_DIRENT): Likewise.
361 2006-09-15 Stepan Kasal <kasal@ucw.cz>
363 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Eliminate the
364 expansion of AC_CHECK_FUNCS.
366 2006-09-14 Stepan Kasal <kasal@ucw.cz>
368 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
369 mistaken comment: the path has to be relative; do not use
370 the path at runtime.
372 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
374 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the
375 argument to `--prefix' for sub-configure scripts.
376 Pass `--silent' to sub-configure scripts.
377 * tests/torture.at (Configuring subdirectories): Add tests
378 for both changes.
379 * doc/autoconf.texi (Setting Output Variables): Fix example to
380 not show `--silent' being passed to a `configure' re-run.
382 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
384 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
385 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
386 for the existence of the directory at configure-time. That's
387 too late, anyway. Problem reported by Stefan Seefeld.
389 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
390 7.1.4 /usr/bin/posix/sh described by Tim Rice in
391 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
393 2006-09-11 Stepan Kasal <kasal@ucw.cz>
395 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
396 works with GNU M4 1.4.3 again; make the normalized form
397 match the current m4 message; fix the description.
398 * test/tools.at (autom4te cache): Adapt to the change.
400 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
402 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
403 to catch glibc bug 2821
404 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
406 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
407 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
408 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
409 assume C89.
411 2006-09-08 Stepan Kasal <kasal@ucw.cz>
413 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the
414 preselections ...

421 AM_ENABLE_MULTILIB.
423 2006-09-05 Paul Eggert <eggert@cs.ucla.edu>
425 * doc/autoconf.texi (Preset Output Variables): srcdir and
426 top_srcdir are not necessarily relative. Problem reported
427 by Dries Kimpe.
429 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
431 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
432 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
433 accept files with extension `.f'. For consistency, also prefer
434 xlf over f77.
435 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
436 from last patch.
438 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>

451 before AC_PROG_FC, due to a bug in Autoconf.
453 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
455 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
456 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
457 except the first two arguments are reversed.
458 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
459 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
460 caches nor outputs a diagnostic. Suggested by Bruno Haible.
461 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
462 equivalent to the old AC_COMPUTE_INT.
463 (AC_COMPUTE_INT): No longer caches or reports. New signature.
464 All uses changed to AC_CACHE_CHECK_INT.
465 * tests/base.at (AC_CACHE_CHECK_INT): New test.
466 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.

470 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
471 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
472 programs should use their Gnulib counterparts.
473 * doc/autoconf.texi (Particular Functions): Likewise.
474 (Macro Names, testsuite Invocation): Replace uses of these
475 obsolete macros with uses of non-obsolete macros.
477 2006-08-29 Eric Blake <ebb9@byu.net>

485 mistakenly swapped on 2006-08-15.
487 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
489 * NEWS: Version 2.60a.

504 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
505 for the default, which the user can override.
506 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
507 deal with LEXLIB.
508 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
509 didn't work if some values were cached but not others. Test for
510 broken lex libraries like native ia64-hp-hpux11.22; see
511 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
512 work around the problem by preferring an empty LEXLIB to -lfl or
513 -ll. Let the user set LEXLIB='' to indicate no library needed.
515 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
516 * README: Likewise.

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

658 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
659 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
660 this.
662 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
664 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
665 problems with arg script text that doesn't end in newline, and

686 Fix test suite failures reported by Pierre in
687 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
688 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
689 the compiler created a file "b.out" when it didn't create anything
690 at all.
691 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
692 Discard stderr too, when invoking the test script.

709 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
710 compiler complains about it, even if things works after the
711 complaint. Problem reported by Peter O'Gorman.
713 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
714 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
715 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
717 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
719 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
720 after -R regardless of host. Patrick Welche reports that this
721 fixes things on NetBSD 3.99.
723 * NEWS: Recommend M4 1.4.5.
724 * README: Likewise.
725 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

727 to match M4 1.4.5.
729 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
731 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
732 under AC_C_VOLATILE.
733 (Volatile Objects): Be a little less skeptical about what
734 "volatile" means. Derived from thoughts by Ben Pfaff in
735 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
737 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
739 * doc/autoconf.texi: Fix some typos.
741 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
743 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
744 more globally, since the 2006-06-30 patch didn't suffice. Problem
745 reported by Keith Marshall. Also, don't bother with builddir2,
746 since it shouldn't be needed any more.
748 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
750 * doc/autoconf.texi (Generic compiler characteristics):
751 Document AC_COMPUTE_INT. Fix wrong statements on Default
752 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
754 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
755 (_AC_COMPUTE_INT): Add obsoletion warnings.

761 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
763 * doc/autoconf.texi (Volatile Objects): New section.
765 * NEWS: Document previous change.
767 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
769 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
770 Require that long long int be at least 64 bits wide. C99 requires
771 this and enough programs depend on it so we should check for it.
772 Bruno Haible reports in
773 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
774 that long long int is 32 bits wide with some nonstandard compilers.
775 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
777 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
779 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
780 to a nonexistent file, so that we don't have to worry about
781 a local site configuration that doesn't use /usr/local.
782 Problem reported by Keith Marshall in
783 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
785 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
787 * doc/autoconf.texi: Be more consistent about using @acronym with
788 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
789 quite right (it talked about "OSF/Tru64", even though the
790 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
791 and it even mentioned "OSF 4"!) and at this point there's little
792 reason to talk about OSF any more, since it died in 1994.
793 (Specific Compiler Characteristics): Simplify example of
794 negative-size array.
795 (File Descriptors): Reorder to make the text flow better.
796 Remove joke about "appreciate the various levels"; I didn't get it.
797 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
798 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
799 (File Descriptors, Limitations of Usual Tools):
800 Tone down the advice against renaming or removing open files.
801 (Limitations of Usual Tools): Add a new section, on 'rm'.
803 2006-06-26 Stepan Kasal <kasal@ucw.cz>
805 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
806 -lXt in LIBS, idea from Karsten Hopp; this was due since
807 this change:
809 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
810 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
811 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
812 (which belong to Xt, not X itself). See Debian bug 327655.
814 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
816 * configure.ac (AC_INIT): Bump to 2.60a.
817 * NEWS: Update.
819 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
821 Version 2.60.
823 * configure.ac, NEWS: Update.
825 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
827 * config/texinfo.tex: Sync from upstream.
829 * bin/autom4te.in (handle_traces): Transform the `@S|@'
830 quadrigraph correctly in traces.
832 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
833 Fix typos.
835 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
836 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
837 not defined.
838 * doc/autoconf.texi (Changed Directory Variables): New node,
839 to document the whole `datarootdir' business a bit better.
840 * NEWS: Update.
841 * tests/torture.at (datarootdir workaround): Extend test.
842 Prompted by report by Alexandre Julliard.
844 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
846 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
847 when using default mode of IBM C 6 for AIX. Problem and two-line
848 fix reported by Larry Jones.
850 2006-06-22 Alexandre Julliard <julliard@winehq.org>
852 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
853 about literal '${datarootdir}' if a definition is found in the
854 output file.
856 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
858 * NEWS: Use "M4" rather than "m4" when appropriate.
859 Problem reported by Eric Blake.
860 * doc/autoconf.texi: Likewise.
861 Use @acronym around BSD, GCC, and GNU when appropriate.
862 (Why GNU M4): Renamed from "Why GNU m4".
863 (Redefined M4 Macros): Mention that Posix
864 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
865 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
866 to int.
868 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
870 * bin/autom4te.in (handle_output): Do not forbid the empty
871 pattern.
872 * tests/tools.at (autoconf: the empty token): New test.
874 2006-06-20 Stepan Kasal <kasal@ucw.cz>
876 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
877 calls, so that we do not care whether they are LIFO or FIFO;
878 in the m4_wrap, do not check which diversion is the topmost
879 one, just check that the stack is balanced at the end.
880 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
881 base diversion forever--pop the previous diversion before
882 opening the new one; consequently, remove the m4_wrap call.
883 * lib/autotest/general.m4 (AT_INIT): Likewise.
884 * tests/m4sugar.at: Do not use
885 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
887 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
888 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
890 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
891 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
892 Rework example of m4wrap token-pasting trouble so that it doesn't
893 care whether it's LIFO or FIFO.
894 Fix some "contrary to"s that are awkward in English.
896 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
898 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
899 to `yes' instead of `int$1_t' if the type is found, for more
900 consistent configure output (where $1 is the number of bits).
901 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
902 Suggested by Bruno Haible.
904 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
905 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
906 with system headers. Report by Bruno Haible.
908 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
910 * config/config.guess, config/config.sub: Sync from upstream.
912 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
913 in order to avoid picking up an older installed frozen m4sh.m4f.
914 Besides an outdated shell startup, this could have been created
915 by an earlier M4 version with incompatible frozen file format.
917 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
919 * README: Recommend m4 1.4.4 instead of 1.4.3..
920 * doc/autoconf.texi: Likewise.
921 (Special Chars in Names): Say that $(.FOO) is portable, as
922 suggested by Stepan Kasal.
923 (Installation Directory Variables, Build Directories):
924 (Automatic Remaking, Subdirectories, Fortran Compiler):
925 (Making testsuite Scripts, Defining Directories):
926 Quote variable usages better.
927 (Making testsuite Scripts): Add clean-local rule to makefile
928 snippet, by Eric Blake.
929 (Installation Directory Variables): Fix table item font.
930 Reword slightly to clarify. Generalize advice about
931 not using special characters to include all file-related
932 vars, not just VPATH.
933 (Special Chars in Variables): Warn about special characters in
934 $(srcdir) too.
935 (Assignments): Clarify default-value example as suggested by
936 Ralf Wildenhues in
937 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
938 (Special Shell Variables): Note leading ./ or ../, as suggested
939 by Eric Blake.
940 (Limitations of Builtins): Under cd, warn about CDPATH.
941 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
942 Ralf Wildenhues.
944 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
946 * doc/autoconf.texi (Configuration Actions): Remove duplicate
947 `@var', for texi2html.
948 (Systemology): Some more word wrapping, for DVI output.
949 (autom4te Invocation): The short option for `--melt' is `-M',
950 not `-m'.
952 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
954 * doc/autoconf.texi: More formatting and English tweaks,
955 many suggested by Ralf Wildenhues.
956 Reword to avoid "@code{...}'s" and the like, since it's ugly
957 with Emacs info mode. discontents -> woes.
958 Put a few "will"s back. time stamp -> timestamp.
959 side-effect -> side effect.
961 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
963 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
964 Warn about $@ not persisting. Problem reported by Julien Danjou in
965 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
966 (Special Chars in Names): Renamed from Leading _ in Macro Names.
967 Mention other special chars, too.
969 2006-06-14 Eric Blake <ebb9@byu.net>
971 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
973 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
975 * doc/autoconf.texi: Some systematic minor improvements, as
976 follows. Use "makefile" when talking about makefiles
977 generally (which might be named "makefile" or "Makefile" or even
978 "foo.mk"), "Makefile" when talking about a specific makefile
979 called "Makefile". This unclutters the text from weird quotes
980 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
981 values" rather than "@var{foo}s" and similar constructs containing
982 "}s". Use "Make rules" rather than "Makefile rules". Minor
983 English-language improvements. Change the prefix "sub-" to "sub"
984 and "re-" to "re".
985 Put blank lines around examples more consistently.
986 Avoid "rather" and "very" as intensifiers.
987 Avoid "will" as an auxiliary.
988 (Limitations of Make): Split this node into....
989 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
990 (Leading _ in Macro Names, Backslash-Newline-Newline):
991 (Backslash-Newline Comments, Long Lines in Makefiles):
992 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
993 (obj/ and Make, make -k Status, VPATH and Make):
994 (VPATH and Double-colon, $< in Explicit Rules):
995 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
996 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
997 New nodes, resulting from splitup of Limitations of Make.
998 All cross-references changed. Raise the top node from
999 a section to a chapter, and all subnodes accordingly.
1000 Redo the introductory wording to match the new organization.
1001 (Installation Directory Variables): Use an example that is
1002 closer to what Autoconf actually does. Mention that VPATH's
1003 value should not contain metacharacters or white space.
1004 (Fortran Compiler): Fix a VPATH bug in an example.
1005 (Leading _ in Macro Names): Mention that this problem is no longer
1006 of practical concern.
1007 (VPATH and Make): Reword the advice to make it clearer
1008 that Autoconf and Automake support VPATH in non-GNU make, but
1009 many packages have bugs in this area.
1010 ($< in Explicit Rules): Refer to Build Directories rather
1011 than using a (non-VPATH-safe) example.
1012 (Automatic Rule Rewriting): Mention the sort of disaster that
1013 can ensue with Solaris-style rule rewriting with VPATH.
1015 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1017 * doc/install.texi (Compilers and Options): Weaken the
1018 suggestion to use GNU make for VPATH builds.
1020 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1021 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1023 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1024 in regular expression.
1026 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1028 * doc/autoconf.texi (Installation Directory Variables):
1029 Drop extra @samp from `@table @samp' item.
1030 (Limitations of Usual Tools): Comment fix.
1031 Do not nest @samp just to point to other table items.
1032 (Writing testsuite.at) <AT_CHECK>: The second argument to
1033 `@dvar' is already @samp'ed.
1034 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1035 do not use @var in the second argument.
1037 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1039 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1040 $as_shell.exe too. Problem reported by Andreas Buening in
1041 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1043 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1045 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1046 `unused variable' compiler warning, for `-Wall -Werror'.
1047 Reported by Jaap Haitsma in
1048 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1050 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1052 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1053 case the compiler dumps core. Problem reported for
1054 OpenServer 5.0.7 by Tim Rice in
1055 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1056 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1057 Likewise.
1059 2006-06-06 Tim Rice <tim@multitalents.net>.
1061 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1062 "ERROR" only shows up in "make check" output if there is an
1063 error.
1065 2006-06-06 Eric Blake <ebb9@byu.net>
1067 * tests/tools.at (automatically allowed tokens): Fix typo.
1069 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1071 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1073 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1074 typically overflows on x86 CPUs, even though the C standard
1075 requires otherwise.
1077 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1079 * configure.ac (AC_INIT): Bump to 2.59e.
1080 * NEWS: Update.
1082 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1084 Version 2.59d.
1086 * config/texinfo.tex: Sync from upstream.
1088 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1089 seen, invoke libtoolize with `--ltdl' argument.
1090 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1091 * NEWS: Update.
1092 Suggested by Eric Blake.
1094 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1096 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1097 reported by Ralf Wildenhues.
1098 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
1100 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1102 * THANKS: Update.
1104 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1106 * doc/autoconf.texi: Modernize some of the references to Solaris.
1108 2006-06-05 Stepan Kasal <kasal@ucw.cz>
1110 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
1111 message issued by AC_REQUIRE.
1112 * tests/m4sugar.at: Check m4_require's error message.
1113 * tests/base.at: Check AC_REQUIRE's error message.
1114 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1115 to...
1116 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1117 AT_CHECK_M4.
1118 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1119 `expout' as the last parameter.
1120 * tests/tools.at: Adapt to the above change.
1122 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1124 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1125 information about race-free implementations of mkdir.
1127 2006-06-04 Eric Blake <ebb9@byu.net>
1129 * bin/autoreconf.in (help): Document M4 environment variable.
1130 * bin/autoconf.as (Usage): Likewise.
1131 * bin/autom4te.in (help): Likewise.
1132 * doc/autoconf.texi (autom4te Invocation): Likewise.
1134 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1136 * NEWS: GNU make now recommended for VPATH builds.
1137 Mention that some macros are now documented to be obsolescent.
1138 * doc/autoconf.texi:
1139 Prefer "current" to "modern" to describe
1140 currently-used (albeit perhaps old-fashioned) hosts.
1141 Mention which ancient features no longer need to be worried about.
1142 setgid -> set-group-ID
1143 setuid -> set-user-ID (these are the Posix terms)
1144 Fix some misuses of "only".
1145 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1146 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1147 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1148 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1149 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1150 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1151 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1152 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1153 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1154 Mention that these macros are obsolescent.
1155 (Installation Directory Variables): shall -> should
1156 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1157 Mention that it's now safe to use 3 and 4.
1158 (Limitations of Usual Tools): cp -r is now specified by Posix.
1159 Omit longwinded and obsolescent discussion of cp -f.
1160 Modernize discussion of expr, ls.
1161 (Limitations of Make): Modernize discussion of VPATH builds.
1162 Mention $? as a workaround in some cases.
1163 * doc/install.texi (Basic Installation):
1164 Mention "./configure; make; make install" first. Be more
1165 specific about why this file is generic. Remove unnecessary
1166 parens. Remove misleading "only". Remove obsolete advice
1167 about csh. Don't say "configure" takes awhile; say it
1168 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1169 and CC=c99 rather than CC=c89, as these are blessed by current
1170 Posix. Recommend GNU make if doing a VPATH build.
1172 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1174 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1175 examples involving shell prompts.
1177 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1178 and Paul Eggert <eggert@cs.ucla.edu>
1180 * doc/autoconf.texi (Here-Documents): Add details about the
1181 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1182 use "here-documents" instead of "here documents".
1184 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1186 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1188 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1190 * doc/autoconf.texi (File System Conventions): Warn about ":"
1191 anywhere in directory names.
1193 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1195 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1196 about quoting the case statement, just in case.
1197 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1198 was fixed in ksh93g; reported by Ralf Wildenhues.
1200 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1202 * doc/autoconf.texi (System Services): Do not document
1203 overriding EXEEXT via ac_cv_exeext=ext.
1204 (Particular Programs) <AC_PROG_MKDIR_P>:
1205 Document that ${MKDIR_P} understands --.
1206 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1207 comment.
1209 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1211 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1212 argument with leading hyphen. Problem reported by Paul Eggert.
1214 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1216 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1217 about quoting ac_try: quote all of it, if any of it seems suspicious.
1218 This means we don't have to worry about ${ or sed any more.
1219 Also, double-quote the case statement, to work around misuses via
1220 underquoting as reported by Ralf Wildenhues in
1221 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1222 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1223 undocumented and dangerous macro.
1224 Problem reported by Ralf Wildenhues in
1225 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1227 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1229 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1230 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1231 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1233 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1235 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1236 since evidently some packages rely on the old, broken behavior.
1237 Problem reported by Ralf Wildenhues in
1238 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1239 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1240 pre-2006-05-26 definitions, but leave in the comments that
1241 these macros are dangerous and should not be used.
1242 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1243 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1244 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1245 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1246 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1248 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1250 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1251 the use of 'tr', since this is our only use of 'tr'.
1253 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1254 and Paul Eggert <eggert@cs.ucla.edu>
1256 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1257 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1259 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1261 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1262 the output file in the `${datarootdir}' test.
1264 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1265 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1267 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1268 mention of `datarootdir' in the input file(s), but literal
1269 `${datarootdir}' in the output file, and we haven't warned yet,
1270 then warn as well: the user may have (erroneously) used
1271 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1272 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1273 * tests/torture.at (datarootdir workaround): Extend this test.
1274 * NEWS: Update.
1276 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1277 and Paul Eggert <eggert@cs.ucla.edu>
1279 * doc/autoconf.texi (autoheader Invocation): The first argument to
1280 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1281 alternatives and clear up the language a bit.
1283 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1285 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1286 ac_config_guess, ac_config_sub, ac_configure.
1287 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1288 Fix typo that prevented an unnecessary space from being removed.
1289 Problems reported by Ralf Wildenhues in:
1290 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1292 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1294 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1295 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
1296 Don't use the term "thread-safe" to talk about mkdir race
1297 conditions, since the problem is more a process than a thread
1298 issue. Problem reported by Stepan Kasal in:
1299 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
1300 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
1301 the test for 'install' more closely. Look at MKDIR_P first.
1302 Look in the PATH, and at /opt/sfw/bin.
1303 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1304 Don't bother to try mkdir -p, since we already check mkdir --version;
1305 just look at the version number. (There's no easy way to check
1306 for race-free implementations.)
1307 * tests/tools.at (autoconf: subdirectories): Adjust to above
1308 changes, since MKDIR_P now might end in "/mkdir -p".
1310 * doc/autoconf.texi (autoheader Invocation): Mention that the
1311 first arg of AC_DEFINE_UNQUOTED must be a literal.
1312 Problem reported by Ben Pfaff in
1313 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1315 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1316 * doc/autoconf.texi (Special Chars in Variables): New section.
1317 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1318 (Installation Directory Variables): Quote $(datadir) better.
1319 (Limitations of Builtins): Describe some of eval's trickiness.
1321 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1322 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1323 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1324 in front of every arg, not just trailing args. Quote apostrophes.
1325 (_AC_EVAL_ECHO): New macro.
1326 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1327 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1328 removed.
1329 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1330 exposed by quoting of eval argument. Put the command on line line
1331 so it logs better.
1332 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1333 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1334 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1335 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1336 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1337 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1338 Use eval more safely.
1339 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1340 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1341 to be replaced.
1342 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1343 lines, exposed by quoting of eval argument.
1345 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1346 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1348 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1349 initialization of `ac_cv_exeext', do not override it if it was
1350 already set, unless it was set to `no', for compatibility with
1351 Autoconf-2.13, and comment this.
1352 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1353 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1354 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1355 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1356 Document that this test may be overridden by setting
1357 `ac_cv_exeext'.
1359 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1361 Revert these two patches:
1363 2006-04-06 Eric Blake <ebb9@byu.net>
1364 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1365 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1366 2006-04-01.
1368 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1369 Clean up _AC_COMPILER_EXEEXT* macros.
1370 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1371 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1372 ac_file to the name of the default output file and call
1373 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1374 initial `rm' of the candidate files...
1375 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1376 the same list in subsequent `rm' calls, and for the temporary
1377 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1378 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1379 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1380 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1381 no longer needed) by libtool. Make it a cache check.
1382 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1383 copied here by mistake.
1384 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1385 _AC_COMPILER_EXEEXT.
1386 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1387 _AC_COMPILER_OBJEXT directly.
1388 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1390 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1392 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1393 Fix description of how the buggy `sed' works.
1395 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1397 Sync from Automake:
1399 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1400 ENOLCK. Only mention `make -j' when applicable. Only raise
1401 fatal errors when `make -j' is involved. Improve error message.
1403 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1405 * doc/autoconf.texi (Here-Documents): We now know more about
1406 the variable expansion in here documents bug.
1407 Thanks to Tim Rice and Stepan Kasal.
1409 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1410 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1412 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1414 * tests/autotest.at (Multiline command from M4 expansion):
1415 No failure to be expected if the shell quotes newlines in
1416 commands in the `set -x' output. Report by Tim Rice.
1417 * THANKS: Update.
1419 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1421 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1422 expansion in the here-documents used by config.status, as that
1423 runs afoul of the Korn shell version M-12/28/93d bug described in
1424 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1425 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1426 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1428 2006-05-23 Jim Meyering <jim@meyering.net>
1430 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1431 Fix typo introduced with 2006-04-02 change. It reversed the sense
1432 of the test.
1434 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1436 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1437 ac_dB slightly, to save bytes in the script.
1438 Max out at 50 lines, rather than 96; this is more likely
1439 (though not guaranteed) to avoid obscure 'sed' failures.
1441 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1443 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
1444 `tr -d -' as bad option argument. Work around this by deleting
1445 an unrelated character.
1446 Report by Tim Rice <tim@multitalents.net>.
1448 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
1449 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1450 Stepan Kasal <kasal@ucw.cz>
1452 * doc/autoconf.texi (Particular Programs): Do not promise that
1453 we always prefer the GNU version of the program, and that we
1454 search according to PATH; both rules can have exceptions.
1455 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
1456 AC_PROG_SED. Move descriptions of limitations
1457 to the Limitations of Usual Tools section.
1458 (Limitations of Usual Tools) <sed>: Mention script length
1459 limitations with Solaris /usr/ucb/sed.
1460 <grep>: Fix wording for empty alternative. Mention that -c and
1461 -l should not be combined, and that -E and -F should not be
1462 combined.
1464 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1465 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1467 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
1468 limits in Solaris 8 /usr/ucb/sed by testing a long script.
1470 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1472 * doc/autoconf.texi (Defining Symbols): Literal parameter of
1473 AC_DEFINE is now passed to m4_pattern_allow.
1474 * NEWS: Mention that; likewise for AC_SUBST.
1475 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
1476 the parameter to m4_pattern_allow.
1477 * tests/tools.at: Add a check for that.
1479 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1481 * lib/autoconf/status.m4: Fix typos.
1483 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1485 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1486 only the files that this macro generates.
1488 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1490 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1491 the HP-UX sed limitation of 99 commands, labels do not count.
1492 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1493 in the comment.
1494 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1496 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1498 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1499 Import the following fix from coreutils:
1501 2006-01-13 Jim Meyering <jim@meyering.net>
1503 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1504 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1505 not double-quote uses of that variable, to accommodate the rare
1506 case in which getmntent is available in none of the libraries
1507 checked. This happens at least on FreeBSD 5.0.
1509 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1511 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
1512 ac_config_guess, ac_config_sub, and ac_configure, since evidently
1513 some other programs unwisely rely on these undocumented vars.
1514 But put in warning comments about them.
1515 Problem reported by Ralf Wildenhues in
1516 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
1517 * NEWS: Document that these variables are intended to go away.
1519 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1521 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
1522 and set the language to C++ (analogous to the equivalent Fortran
1523 tests).
1525 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
1526 * doc/autoconf.texi (C++ Compiler): Document it.
1527 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
1528 * NEWS: Update.
1530 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1532 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
1533 that caused config.status to generate 100-command sed scripts; the
1534 portable limit is 99.
1536 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1538 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
1539 variable `ac_d' instead of `d' to avoid infringing namespace.
1540 Report by Ralf Menzel.
1542 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
1544 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
1545 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
1546 * tests/tools.at (autoconf: subdirectories): New test, taken from
1547 the corresponding problem report by Ralf Wildenhues in:
1548 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
1550 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
1551 Quote some uses of shell variables if they might suffer unexpected
1552 globbing. This doesn't fix all instances of quoting problems that
1553 I found, just the easy ones that look safe.
1554 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
1555 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
1556 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
1557 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
1558 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
1559 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
1560 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
1561 Likewise.
1562 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
1563 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
1565 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1567 * bin/autoreconf.in ($help): Reword according to the manual.
1568 Suggested by Olly Betts.
1570 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
1571 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1573 * bin/autoreconf.in: Pass the directory argument to
1574 `require_configure_ac'. Fix comment.
1575 * tests/torture.at (Configuring subdirectories): Expose this.
1576 Reported by Olly Betts.
1578 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1580 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
1581 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
1582 Automake as follows:
1584 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
1585 `$configure_in' instead of `configure.in', to preserve
1586 directory component.
1588 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1590 * config/config.guess, config/config.sub, config/texinfo.tex,
1591 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
1593 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1595 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
1596 test for C99 conformance; (bool) 0.5 is an integer constant
1597 expression, but (bool) -0.5 is not. Problem reported by Fedor
1598 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
1600 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1602 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
1603 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
1604 Warn about obsolete install-sh files. Remove stray sentence
1605 fragment and fix cross reference.
1606 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
1607 install -d; this undoes the 2006-05-10 change.
1608 (MKDIR_P): Mark with AN_MAKEVAR.
1609 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
1610 that we don't require $INSTALL to be thread-safe. Move comments
1611 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
1612 of AC_PROG_INSTALL. Output a message saying that we're checking
1613 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
1614 MKDIR_P instead of AC_SUBST.
1615 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
1616 Special magic for MKDIR_P, too.
1617 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
1618 a dnl.
1619 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
1621 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1623 Sync from Automake, as follows:
1625 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1626 * config/install-sh: Initialize IFS, so field splitting isn't
1627 turned off later.
1628 * config/mkinstalldirs: Likewise.
1629 * config/missing: Remove superfluous quotes. Replace all uses of
1630 `[' by `test', for consistency, and for..
1631 * config/missing (sed_minuso, sed_output): New variables.
1632 (autom4te, help2man, makeinfo): Use them. Unifies detection of
1633 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
1634 Fixes `missing' to detect `--output' for help2man. Fixes
1635 PR automake/483. Report by Dennis J. Linse.
1636 (autom4te): Document in `missing --help'.
1638 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1640 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1641 * config/install-sh: Don't use 'path' to talk about file names,
1642 as per GNU coding standards. Close a race condition reported by Ralf
1643 Wildenhues and Stepan Kasal. There is still a race condition
1644 on hosts that predate Posix 1003.1-1992, but we can't help this.
1645 Don't mishandle weird characters like space on pre-Posix hosts.
1646 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1647 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1648 AC_PROG_MKDIR_P from AS_MKDIR_P.
1649 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1650 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1651 earlier editions are not (including Automake 1.8.3).
1652 Do not suggest mkinstalldirs for thread-safety.
1653 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1654 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1655 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1656 presence of special characters and race conditions.
1657 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
1658 in Autoconf's name space.
1660 2006-05-10 Bruno Haible <bruno@clisp.org>
1661 and Paul Eggert <eggert@cs.ucla.edu>
1663 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
1664 from Automake with minor changes.
1665 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
1667 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1669 * config/install-sh: Update to Automake CVS version, as follows:
1670 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1671 * lib/install-sh: Simplify the expr implementation of dirname.
1672 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
1673 * lib/install-sh: Handle --, and diagnose unknown options.
1675 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1677 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
1678 `./autom4te' to create `./testsuite', since the `all' target
1679 will ensure its presence, but `installcheck' should not create
1680 the uninstalled wrappers.
1682 * tests/torture.at (Unusual Automake input files): Skip if we
1683 detect automake < 1.8.
1685 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1687 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
1688 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
1689 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
1690 * NEWS: Update.
1692 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1694 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1695 munge (multiple) white space and other oddities.
1696 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1697 single quotes in variable assignment.
1698 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1699 and similar failures by adding multiple spaces, tabs, and other
1700 special characters.
1701 Report and different test suggested by Francesco Romani
1702 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1704 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1705 single quotes, we only need to search for single quotes; this
1706 both simplifies the search pattern, and makes us less
1707 susceptible to `echo' variations for arguments not containing
1708 single quotes.
1709 (_AC_ARG_VAR_VALIDATE): Likewise.
1711 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1713 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1714 `$*' and IFS concatenation issue with traditional shells and
1715 bash-2.04. Report by Seanster@Seanster.com.
1717 2006-05-03 Bruno Haible <bruno@clisp.org>
1719 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1720 precisely which Mac OS X versions have the od problem.
1722 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1724 * doc/autoconf.texi: Use @option systematically.
1726 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1727 and Bruno Haible <bruno@clisp.org>
1729 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1730 about 'od'.
1731 (Integer Overflow): Mention the special case of integer division
1732 overflow.
1734 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1736 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1737 traditional shells like the Solaris one that do not use the
1738 first IFS character for assembling `$*'.
1739 Prompted by a related report from autoconf_bug@nro.ca.
1741 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1742 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1744 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1745 Mention more problems with the -e option.
1747 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1749 * NEWS: Typo.
1750 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1752 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1753 in URLs to improve DVI formatted output (requires texinfo 4.6).
1754 (System Services, Systemology, Shellology): Likewise.
1755 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1756 output.
1758 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1759 continuous text.
1760 (Runtime): Fix macro argument names to match description:
1761 `action-if-found' -> `action-if-true' and similarly.
1762 (Obsolete Macros): Likewise.
1763 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1764 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1765 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1767 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1769 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1771 * ChangeLog: Typo.
1772 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1773 DVI output.

1784 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
1785 (Integer Overflow, Null Pointers, Buffer Overruns):
1786 (Floating Point Portability, Exiting Portably): New sections.
1787 (Writing Test Programs): Fix some langauge. Recommend exiting
1788 with status 1, not merely nonzero. Clarify exit declaration.
1789 (Run Time): Move C exit status stuff to new Exiting Portably section.
1790 (Systemology): Mention Posix and levenez. Update v7 reference.
1791 (Portable Shell): Mention the Posix shell.
1793 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1795 * bin/autoconf.as (me): Replace by as_me.
1797 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1799 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1800 since as_me isn't set yet.
1802 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1804 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1805 a few minor bugs in this area.

1818 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
1819 (AS_BASENAME): Use "basename --" to protect against leading "-".
1820 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
1821 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1822 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
1823 (_AS_DIRNAME_PREPARE): Likewise.
1824 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
1825 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
1826 (AS_DIRNAME): Use "dirname --".
1828 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1830 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1831 of "run time" and "run-time" changed to "runtime", for consistency.
1832 * lib/autoconf/fortran.m4: Likewise (in comment).
1833 * lib/autoconf/functions.m4: Likewise.
1834 * lib/autoconf/general.m4: Likewise.
1835 * lib/autoconf/headers.m4: Likewise.
1837 * doc/autoconf.texi (Run Time): Document the exit status situation
1838 with more accuracy and detail.
1840 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1842 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1843 Archive is not officially `GNU' any more. Update URL.
1844 (Defining Directories): Likewise
1845 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1847 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1849 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1850 newline from the `trap' code to finish `config.log'; the NetBSD
1851 /bin/sh resets the exit status after an empty command, as
1852 documented in doc/autoconf.texi.
1853 Reported by Dalibor Topic <robilad@kaffe.org>.
1855 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1857 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1858 Suggested by Bruno Haible.
1860 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1862 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1863 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1864 Instead, just list the shells that we know work.
1865 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1866 changed. Be more cautious about the _cv_ variable.
1867 * tests/tools.at (Syntax of the shell scripts): Check the
1868 _cv_ variable once, at first, to avoid an internal autoconf error
1869 when sh -n does not work.
1871 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1873 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1875 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1877 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1878 use ">&-" since we're only 99.999% sure that this is portable,
1879 and since the MinGW bug is fixed in a different way.
1880 * lib/autotest/general.m4 (AT_INIT): Likewise.
1882 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1884 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1885 before opening config.log, to avoid hitting a bug on MinGW.
1887 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1889 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1890 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1891 This works around a MinGW bug reported by Eric Paire.
1892 Make sure that all writes to the log file append to it,
1893 rather than possibly losing data.
1894 * lib/autotest/general.m4 (AT_INIT): Likewise.
1896 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1898 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1899 description.
1901 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1903 * NEWS: Update.
1905 * configure.ac (AC_INIT): Bump to 2.59d.
1907 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1909 Version 2.59c.
1911 * Makefile.maint (news-date-check): Do not require a leading `*'
1912 before the release date in NEWS.
1914 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1915 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1917 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1918 the instantiated file do not contain the string 'datarootdir'
1919 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1920 @mandir@, replace the reference '${datarootdir}' by the value.
1921 * tests/torture.at (datarootdir workaround): New test.
1922 * NEWS: Advertise this temporary fixup.
1923 Based on a patch by Bruno Haible, reported and analyzed by
1924 Paul Eggert and Noah Misch.
1926 2006-04-12 Eric Blake <ebb9@byu.net>
1928 * tests/autotest.at (Debugging a failed test): Fix comment.
1930 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1932 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1933 all the changes since 2006-04-07.
1935 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1937 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1938 succeeded, but `ln -s file dir' failed, take care to remove the
1939 leftover target before the next test, to prevent its spurious
1940 failure; also make sure `ln file dir' works before selecting it.
1941 Thanks to Keith Marshall for pointing this out.
1942 * THANKS: Update.
1944 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1945 assignments in `at_debug_args', so that we put them correctly
1946 in the `run' script.
1947 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1948 Reported by Eric Blake.
1950 2006-04-11 Eric Blake <ebb9@byu.net>
1952 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1953 top-level tests after micro-suite has been run. Used in...
1954 (Debugging a successful test, Debugging script and environment),
1955 (Debugging a failed test): ...these new tests. The first of these
1956 is fixed by...
1957 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1958 macro, split out from...
1959 (AT_INIT): ...here, so that using -d also generates a run script.
1960 Document that -d inhibits top-level logging.
1961 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1962 inhibits top-level logging; debug scripts are created.
1964 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1965 check.
1966 * tests/autotest.at (Empty test, Empty check): New test to check it.
1968 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1969 from gcc.
1971 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1973 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1974 the files if a problem appears. Make the empty *.at files
1975 read-only, too. Proposed by Ralf Wildenhues.
1977 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1979 * config/Makefile.am: Add comment to force updated Makefile.in.
1981 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1982 space only patch to this file, this patch causes the Makefile.in
1983 files that include freeze.mk to be updated, and thus have a
1984 newer time stamp again, which in turn makes a pristine CVS
1985 checkout have correct time stamps.
1987 * Makefile.maint (cvs-sv): New macro, to be used..
1988 (config.guess-url_prefix, config.sub-url_prefix)
1989 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1990 point to CVS text checkout of Gnulib files.
1991 (copyright-check): Bump current year.
1992 (announcement): Do not hard-wire `./announce-gen'.
1993 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1994 correctly.
1995 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1996 `chmod +x'.
1997 (wget_files): Update config.guess, config.sub, texinfo.tex by
1998 `wget-update', now that their URLs work again.
2000 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2002 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2003 Problem noted by Paul D. Smith.
2005 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2007 * doc/autoconf.texi: Remove unused words from word list.
2008 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2009 .x-sc_trailing_space: New files.
2011 * doc/standards.texi: Sync from gnulib.
2013 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2014 `LIBOBJDIR' as experimental.
2016 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2017 with a target directory; it's internally implemented as `cp'
2018 anyway, but since Autoconf advertises the possibility to use
2019 a target directory when LN_S is `ln -s', we need to find out.
2020 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2021 analyzed by Keith Marshall <keith.marshall@total.com>.
2023 * THANKS: Update.
2025 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2027 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2028 confdefs.h as-is. In general, if it has backslash-newline or the
2029 like, then it doesn't work either to sort or to remove empty
2030 lines.
2032 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2034 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2036 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2038 * lib/autom4te.in (Automake-preselections): Preselect
2039 _AM_SUBST_NOTMAKE.
2041 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2043 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2044 apostrophe within a single-quoted string, as this is the usual
2045 tradition and is easier to read than '"'"'. Don't rely on the
2046 shell treating "$/" like '$/'. Use a more-consistent indenting
2047 style for the trap.
2049 2006-04-09 Eric Blake <ebb9@byu.net>
2051 * tests/autotest.at (Backquote command substitution),
2052 (Multiline backquote command substitution): Remove mistaken
2053 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2054 applied...
2055 (Parenthetical command substitution, Multiline parenthetical
2056 command substitution): here.
2058 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2060 Import macros from gnulib (often changing their name).

2074 (Pointers): Add Gnulib URL.
2075 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
2076 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
2077 Gnulib section.
2078 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
2079 suggest a #define rather than a typedef for _Bool, and mention
2080 Gnulib rather than trying to substitute stdbool code.
2081 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
2082 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
2083 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

2086 headers too.
2087 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
2088 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2089 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2090 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2091 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2092 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2093 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2094 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2095 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2096 (Coding Style). Don't mention m4_expand_once.
2097 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
2098 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
2099 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.

2105 (AC_HEADER_ASSERT): New macro.
2106 (AC_HEADER_STDBOOL): Don't assume "#error" works.
2107 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
2108 Catch a bug in an HP-UX C compiler.
2109 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
2110 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
2111 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

2114 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
2115 New macros.
2117 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
2118 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
2120 2006-04-08 Stepan Kasal <kasal@ucw.cz>
2122 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
2123 of the warning introduced by the 2001-08-28 change.
2125 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
2126 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2128 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
2129 variables shall be overriden by the cache.
2130 * tests/torture.at (AC_ARG_VAR): Test also with a first value
2131 that contains braces.
2133 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2135 Revert the patch from 2006-04-01 and only improve
2136 _AS_DETECT_BETTER_SHELL:
2138 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2139 skip nonexistent directories.
2140 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2141 only shell candidates which exist.
2142 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2143 * lib/autotest/general.m4 (AT_INIT): No need to give three
2144 parameters to _AS_PATH_WALK.
2146 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2147 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2149 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2150 distinguish m4sugar macros.
2151 * tests/tools.at (autoupdating with aclocal and m4_include):
2152 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2153 test case by Noah Misch <noah@cs.caltech.edu>.
2155 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2157 Revert my change from 2006-03-17, in other words:
2158 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2159 and DUALCASE=1.
2160 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2161 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2162 it is set.
2164 2006-04-07 Eric Blake <ebb9@byu.net>
2166 * doc/autoconf.texi (Programming in M4sh): Document that
2167 AS_MKDIR_P exits the script on failure.
2168 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2170 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2172 * config/elisp-comp, config/install-sh, config/mdate-sh,
2173 config/missing, config/mkinstalldirs: Sync from Automake.
2175 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
2176 from Automake.
2178 * doc/make-stds.texi: Sync from gnulib.

2182 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2183 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2184 2006-04-01.
2186 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
2187 Eric Blake <ebb9@byu.net>,
2188 Paul Eggert <eggert@cs.ucla.edu>,
2189 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2191 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2192 whether `set' quotes correctly: redirect stderr of the tested
2193 `set', and use a subshell, for Ultrix; use `sed' instead of
2194 `grep' for zsh `set' which may write binary output; match only
2195 at the beginning of a line, to avoid false positives.
2196 In order to avoid false positives by unrelated variables with
2197 multiline content, put the dump algorithm in a subshell and
2198 unset all variables containing newlines (except some which are
2199 special to the shell). Warn about cache variables that are
2200 unset.
2202 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2204 * config/config.guess, config/config.sub, config/texinfo.tex:
2205 Sync from upstream.
2207 * tests/mktests.sh: Reword comments.
2209 * tests/mktests.sh: Only skip internal macros starting with
2210 `_AC_' or `__AC_'. Noted by Stepan Kasal.
2211 Update exclusion lists for the test suite to this end:
2212 (AC_ARG_VAR): Do test this now.
2213 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
2214 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
2215 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
2216 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
2218 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
2219 shell issue with double-quoted command substitutions of native
2220 commands.
2221 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
2222 Marshall.
2224 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
2225 no file matches the glob, discard the warning, set `nullglob'.
2226 (syntax-check): Likewise.
2227 (sc_cast_of_x_alloc_return_value): Likewise.
2228 (sc_cast_of_alloca_return_value, sc_error_exit_success)

2230 (m4-check): Likewise.
2231 (sc_system_h_headers): Do not print rule on execution.
2232 (sc_tight_scope): Do not fail for non-existing `src' directory.
2233 (sc_changelog): Skip the Copyright footer.
2234 * lib/autoconf/lang.m4: Remove trailing space.
2236 * lib/autoconf/status.m4: More replacements to
2237 <tab><space> where this makes sense.
2239 2006-04-06 Stepan Kasal <kasal@ucw.cz>
2241 * tests/Makefile.am (maintainer-check-posix):
2242 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
2244 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
2245 ac_config_<foo>s again, sometimes normalized, sometimes not.
2246 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
2247 (AC_CONFIG_COMMANDS): Do not do so here.
2248 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
2249 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
2250 2005-07-25 rewrite. Noticed by Noah Misch.
2252 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
2253 _AC_PRESERVE_HELP_ORDER, ...
2254 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
2256 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
2257 inside m4_expand_once; it is redundant.

2318 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
2319 (exclude_list): Exclude empty macros.

2405 ac_file to the name of the default output file and call
2406 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2407 initial `rm' of the candidate files...
2408 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2409 the same list in subsequent `rm' calls, and for the temporary

2412 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2413 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2414 no longer needed) by libtool. Make it a cache check.
2415 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2416 copied here by mistake.
2417 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2418 _AC_COMPILER_EXEEXT.
2419 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

2455 subordinate tools.
2456 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
2457 * doc/autoconf.texi (autoreconf Invocation): Document it.
2459 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

2493 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
2494 switch all of them on and of when necessary. Fixes the bug when
2495 m4sugar macros (e.g., m4_define) were expanded after the first
2496 automatic update (e.g., after AC_PREREQ or AC_INIT).

2547 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
2549 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3178 not portable; thanks to Paul Eggert and Alexandre.
3180 * NEWS: Fix an old typo.
3182 2005-10-20 Jim Meyering <jim@meyering.net>
3184 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
3185 the latter'', in two places.
3187 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
3189 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
3190 AC_LANG_PROGRAM, fixing a typo. Don't give details about
3191 the inner workings of AC_LANG_FUNC_LINK_TRY.
3192 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
3193 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
3194 by the function rather than ignoring it.
3195 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
3196 comparing its address. Intel's interprocedural optimization was
3197 outsmarting the old heuristic. Problem reported by
3198 Mikulas Patocka.
3200 2005-10-19 Stepan Kasal <kasal@ucw.cz>
3202 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
3204 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
3206 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
3207 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
3209 2005-10-04 Stepan Kasal <kasal@ucw.cz>
3211 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
3212 before removing it (chmod -R u+rwx); there are three instances of this.
3214 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3215 Stepan Kasal <kasal@ucw.cz>
3217 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3218 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3219 make its content writable before removing it. Remove an errorneous
3220 comment from the end, where the logs of the failed tests are copied
3221 to the main log file.
3223 2005-09-27 Stepan Kasal <kasal@ucw.cz>
3225 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
3226 in case the computer is too quick. Double quote the configure.ac
3227 snippets.
3229 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
3230 problems if the testsuite were running too fast.
3232 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3234 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3235 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3236 (which belong to Xt, not X itself). See Debian bug 327655.
3237 * NEWS: Mention this.
3239 2005-09-07 Stepan Kasal <kasal@ucw.cz>
3241 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
3243 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
3245 * config/move-if-change: Don't output "$2 is unchanged";
3246 suggested by Ben Elliston. Handle weird characters correctly.
3248 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3250 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3251 calls, so that the final expansion of this macro is shorter.
3252 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3253 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3254 the cleanup there. Use AS_VAR_* macros, to be more general.
3255 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3257 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3259 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
3261 2005-09-01 Stepan Kasal <kasal@ucw.cz>
3263 * doc/autoconf.texi (Configuration Headers): Add an index entry
3264 for AH_HEADER.
3266 2005-08-26 Pavel Roskin <proski@gnu.org>
3268 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
3269 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
3270 running xmkmf.
3272 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
3274 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3275 The previous patch didn't work, so try a better one.
3277 2005-08-26 Stepan Kasal <kasal@ucw.cz>
3279 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3280 in the example. Reported by Bruno Haible.
3281 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3282 "if $undefined_var;" succeeds with my shell.
3284 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
3285 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
3286 but change the m4_divert_text to m4_divert_once.
3288 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
3290 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3291 Work around bug in Solaris /usr/xpg4/bin/awk.
3292 The bug is present in at least Solaris 8 through 10.
3294 2005-08-24 Stepan Kasal <kasal@ucw.cz>
3296 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
3297 some evil values and relying on the fact that $* concatenates the
3298 parameters by the first character from IFS.
3300 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3301 Stepan Kasal <kasal@ucw.cz>
3303 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
3304 first header appears, define AH_HEADER.
3305 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
3306 Update limitations about when to call AC_CONFIG_HEADERS.
3307 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3308 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3309 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3310 ``Configuration Actions''; fix their index entries.
3312 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3313 options correctly. Process N-M as M-N if M is smaller than N.
3314 Process ranges correctly so that N-N will run only N.
3315 Sort and uniquify the tests that will be run. If there is more
3316 than one test, reinsert the banners for the tests.
3317 * tests/autotest.at (Keywords): Unmark XFAIL.
3319 2005-08-23 Stepan Kasal <kasal@ucw.cz>
3321 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
3322 before passing the macro name to AH_TEMPLATE.
3324 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3325 now opens log after option processing; in particular, --version
3326 and --help do not touch config.log.
3328 * Makefile.maint: Revert the change from 2005-08-12.
3330 2005-08-22 Stepan Kasal <kasal@ucw.cz>
3332 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
3333 common code to...
3334 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
3336 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3338 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
3339 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
3340 Language cleanup.
3342 * doc/autoconf.texi (Defining Symbols, Changed Results):
3343 Prepend to LIBS, not append, in examples.
3345 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3347 When building in place, set srcdir="."; suggested by Tim Van Holder.
3349 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3350 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3351 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3352 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
3353 does not mean "no --srcdir option".
3355 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3357 * tests/autoscan.at (autoscan): New file.
3358 * tests/suite.at: Use it.
3359 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
3360 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
3362 * tests/autotest.at (Keywords): Test keywords combinations.
3364 2005-08-12 Stepan Kasal <kasal@ucw.cz>
3366 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
3367 add "2>&1"; gzip 1.2.4 prints help on stderr.
3369 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3371 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
3372 was pushdef'ed twice while popped only once. Push it only once.
3373 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
3375 2005-07-26 Stepan Kasal <kasal@ucw.cz>
3377 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
3378 prefixed by mere "===", not "configure: === ".
3380 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
3382 * Makefile.maint: Update from Bison.
3384 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3385 "<tab>" in comment, so that the point is understandable.
3387 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3389 Rewrite substantial part of lib/autoconf/status.m4.
3390 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3391 and CONFIG_COMMANDS are not processed in four separate loops.
3392 Instead, there is one main loop. This alows that the common code
3393 is expanded only once, thus config.status (and configure) is smaller.
3395 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3396 the AC_LIST_FILES and cousins macros are no longer used.
3398 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3399 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3400 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3401 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3402 contain the initialization, nor the for loop, nor the associated
3403 commands; all these go to ...
3404 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3405 _AC_OUTPUT_CONFIG_STATUS.
3406 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3407 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3408 (_AC_OUTPUT_FILE): The creation of the sed script ...
3409 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3410 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3411 _AC_OUTPUT_MAIN_LOOP.
3412 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3413 _AC_CONFIG_COMMANDS): Use ...
3414 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3415 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3416 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3417 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3418 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3419 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3420 ... new macros.
3421 (_AC_CONFIG_UNIQUE): Update.
3422 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3423 Replaced by this ...
3424 (_AC_LIST_TAGS): ... new common macro.
3425 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3426 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3427 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3428 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3429 this didn't belong to the `config commands' section.
3430 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3431 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3432 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3433 to the `config commands' section either.
3434 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3435 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3437 ... and many changes to the comments nearby.
3439 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3440 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3441 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3442 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
3443 (#define header templates): The comment at the top of the generated
3444 header now includes the name(s) of the source file(s).
3446 Several unrelated small changes:
3448 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
3449 parameter to AC_DIAGNOSE.
3450 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
3451 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
3452 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
3453 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
3454 with AU::AC_OUTPUT.
3455 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
3456 in AC_OUTPUT doesn't double-quote it either.
3457 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
3458 parameters.
3460 2005-07-10 Stepan Kasal <kasal@ucw.cz>
3462 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
3463 versions of Portland Group compiler produce single- and double-quoted
3464 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
3465 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3467 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3469 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3470 This is a corrected version of yesterday's patch.
3472 2005-07-07 Stepan Kasal <kasal@ucw.cz>
3474 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
3475 path, too; insert a "===" to emphasize the line.
3477 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
3478 ac_cv_build_alias to ac_build_alias.
3479 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3481 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3482 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3483 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3484 (AC_ARG_VAR): ... here.
3485 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3486 target_alias.
3488 Keep a list of all precious variables and process them with one simple
3489 for loop, instead of expanding all commands, or, OTOH, complicated
3490 processing of output of "set".
3491 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3492 variable names in new macro...
3493 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
3494 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
3495 a loop to assign all ac_env_* and ac_cv_env_* variables.
3496 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3497 to INIT_PREPARE.
3498 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3499 its value to shell variable ac_precious_vars and call
3500 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
3501 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
3502 _AC_ARG_VAR_VALIDATE.
3504 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
3505 and the AC_SUBSTs ...
3506 (AC_INIT): ... here.
3508 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
3509 the ac_subst_files section in config.log.
3511 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
3513 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>
3515 * NEWS: New macro AC_C_TYPEOF.
3516 * doc/autoconf.texi (C Compiler): Document AC_C_TYPEOF.
3517 * lib/autoconf/c.m4 (AC_C_TYPEOF): New macro.
3518 * tests/c.at (C keywords): Test AC_C_TYPEOF.
3520 Fix problems reported by Nicolas Joly.
3521 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
3522 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3523 They are generated by the Tru64 v5.1B shell.
3525 2005-07-05 Stepan Kasal <kasal@ucw.cz>
3527 Fix my changes from 2005-07-01; reported by Noah Misch.
3528 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
3529 description, the macro now accepts only a single tag.
3530 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
3532 Fix cases when the varsions of Autoconf and Autotest don't match.
3533 Reported by Noah Misch.
3534 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
3535 at_top_builddir, for compatibility with older autotest.
3536 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
3537 is not set, use at_top_builddir, for compatibility with older
3538 versions of autoconf.
3540 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
3542 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
3543 Problem reported by Patrick Welche.
3545 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
3547 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
3548 sed substitution command, so that we allow | in program prefixes
3549 and program suffixes. (& is a problem anyway; we're not fixing
3550 that here.)
3551 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
3552 configure_input, top_builddir, srcdir, etc.
3553 * lib/autotest/general.m4 (AT_INIT): Likewise, for
3554 PATH_SEPARATOR in AUTOTEST_PATH.
3556 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
3558 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
3559 for loop over config.site files using `set', to allow
3560 directory names containing IFS characters.
3562 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
3564 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
3565 directories with weird names. Apparently some people like living
3566 on the edge. However, improve the test that "pwd" actually does
3567 report a name for the working directory.
3568 * NEWS: Remove the claim that we test for funny chars in dir names.
3570 2005-07-01 Stepan Kasal <kasal@ucw.cz>
3572 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
3573 replaced ...

3577 (AC_CONFIG_SUBDIRS): Call _AC_CONFIG_UNIQUE in a m4_foreach_w loop.
3579 2005-06-30 Stepan Kasal <kasal@ucw.cz>
3581 * doc/autoconf.texi (Configuration Headers): Change the explanation
3582 about #include <config.h>.
3583 (Generic Functions): Mention the Gnulib project.
3584 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
3586 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
3587 document to output the default config_* lists to config.status.
3588 Don't recognize option --file, if the functionality is not there.
3589 Likewise for --header; moreover, recognize --he and --h as shortcuts
3590 for --help in that case.
3592 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
3593 matches the order of execution. No code changed.
3595 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3597 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
3598 single-quoted -cmdline argument in Portland Group compiler.
3599 Reported against LAM by Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3601 2005-06-30 Alexandre Duret-Lutz <adl@gnu.org>
3603 * lib/autom4te.in (Automake-preselections): Preselect AC_SUBST_TRACE.
3605 2005-06-29 Stepan Kasal <kasal@ucw.cz>
3607 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
3608 descriptors to child processes; reported by Norman Gray.
3610 2005-06-29 Stepan Kasal <kasal@ucw.cz>
3612 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
3614 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
3615 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
3616 (AC_SUBST): Call it.
3617 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
3618 the directory specific variables; but don't call it for configure_input.
3620 2005-06-28 Derek Price <derek@ximbiot.com>
3622 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
3623 addition.
3625 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
3627 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
3628 directory have inherent problems with special characters like spaces,
3629 due to limitations in Make syntax. Problem reported by Alexandre
3630 Duret-Lutz.

3644 from Justace Clutter.
3645 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
3646 variable into diagnostic. Make the diagnostic an error, not a warning,
3647 because we really don't support spaces and suchlike in dir names.
3648 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3649 Don't worry about backslashes in srcdir; it can't happen now.

3660 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
3662 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
3663 that '\|' is not allowed in BREs; recommend using newline separated

3678 (Special Shell Variables): Fix sed code this in the example.
3679 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
3680 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
3682 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
3683 expand to the empty list. Don't use two pairs of m4_changequote,
3684 it's not necessary.
3686 2005-06-20 Derek Price <derek@ximbiot.com>
3688 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
3690 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
3692 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
3693 * doc/autoconf.texi:
3694 Don't mention Solaris versions so much, if a
3695 problem is common to all extant versions of Solaris. Say "SunOS
3696 4" instead of "SunOS" for SunOS 4.
3697 (awk): Mention more of the limitations of traditional Awk.
3698 (cat): Don't talk about cat -v.

3714 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
3716 * doc/autoconf.texi: "filesystem" -> "file system".
3717 "behaviour" -> "behavior".

3719 * lib/autoconf/general.m4: Omit blank after ":" sed command,
3720 as per POSIX.
3721 * lib/m4sugar/m4sh.m4: Likewise.
3722 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
3723 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
3725 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
3726 (.x.1): Ignore the time stamp in the .TH line when deciding whether

3740 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3741 -u, since it outputs chatter if the input files are the same.
3742 Problem reported by Ralf Menzel.
3744 2005-06-08 Derek Price <derek@ximbiot.com>
3746 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3747 renaming them since they are about to be redefined anyhow.
3749 2005-06-08 Derek Price <derek@ximbiot.com>
3751 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3752 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3753 Move m4_undefine to alphabetical order.
3755 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
3757 * README: Recommend GNU M4 1.4.3 or later.
3758 * doc/autoconf.texi (Introduction): Likewise.
3759 Reword to avoid some formatting glitches.
3760 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
3761 Clarify explanation of HP compiler bug.
3762 Redo example output tp match current CVS snapshot.
3763 Use @example.org in email addresses when the examples
3764 might get inadvertently cut-and-pasted into user code.
3765 Remove example of autom4te usage that doesn't seem to work now.
3766 Use modern AC_INIT (except when the example is meant to be
3767 shown with Autoconf 2.13).
3768 Update ksh info for Solaris 9 and later.
3769 KB -> kB.
3770 Modernize description of Automake versions a bit.
3771 Don't claim a future version of Autoconf is near.

3777 follows its own advice about quoting better.
3778 Reword to avoid some formatting glitches.
3779 * doc/installt.exi: Reword to avoid some formatting glitches.
3781 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3782 Tru64 ksh pattern matching bug. Reported against Libtool by
3783 Albert Chin <libtool@mlists.thewrittenword.com> and
3784 Nicolas Joly <njoly@pasteur.fr>.
3786 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3788 m4_cdr of one-member list was [[]] (one-member list containing an
3789 empty string) instead of [] (an empty list. Callers were skewed to
3790 match this misbehaviour. As a consequence of this:
3791 - m4_foreach([x], [], [foo]) expanded to `foo', while
3792 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3793 This bug has been fixed:
3795 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3796 expand to an empty string; print error msg if called without
3797 an argument list.
3798 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3799 misbehaviour; handle [] and [[]] correctly.
3801 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3803 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

3805 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
3807 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3809 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3810 swallow records with more than 99 fields.
3811 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3812 parse the long line.
3814 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3816 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3817 swallow literals longer than 399. Reported by Ralf Wildenhues.
3818 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
3819 to workaround this limitation.
3821 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
3823 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
3824 to gfortran, and make these the first two compiler names
3825 checked (following the general autoconf preference for gcc).
3827 2005-06-03 Stepan Kasal <kasal@ucw.cz>
3829 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3830 (DISTCLEANFILES): Remove $(check_SCRIPTS).
3831 (testsuite): Make sure autotest.m4f is up-to-date before using it.
3833 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
3835 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3836 expression of unbounded size when processing the --list
3837 option. This runs afoul of a limit of 399 bytes per regular
3838 expression on AIX. Problem reported by Ralf Wildenhues.
3840 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

3843 * doc/autoconf.texi (Particular Headers): Reword example
3844 for multiline stdbool replacement.
3845 (Setting Output Variables): Reword text a bit. Don't
3846 give all the details about |#_!!_#|.
3847 Reword description of line replacement.
3849 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3851 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3852 now contain newlines, and substituted files must be referenced on
3853 a line alone; the sed scripts to substitute them are now very
3854 different.
3855 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3856 commands can be put in a sed script portably.
3857 * doc/autoconf.texi (Setting Output Variables): Document above
3858 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
3859 use of multiline substitution.

3869 * tests/local.at: Don't attempt to check for negated character
3870 classes in shell scripts. The test was too brittle.
3872 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3874 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3875 * doc/autoconf.texi (Limitations of Builtins): Document this
3876 limitation.
3878 2005-05-24 Stepan Kasal <kasal@ucw.cz>
3880 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
3881 common code; used in many places in the tree.

3888 messages when ac_unique_file is not found.
3889 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3890 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
3891 commands, for consistency with AC_MSG_ERROR and such.
3893 * bin/autoconf.as: Make more use of "shift 2" in option processing.
3895 * bin/Makefile.am: Merge the two rules for creating scripts.

3903 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3905 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
3906 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3907 (ac_top_builddir): ... this ...
3908 (ac_top_build_prefix): ... to this; the old name is also kept, for
3909 backward compatibility.
3910 (ac_top_builddir_sub): New variable, without the trailing slash,
3911 always nonempty.
3912 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
3913 * doc/autoconf.texi (Configuration Actions): Rename
3914 ac_top_builddir to ac_top_build_prefix.
3915 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

3924 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3926 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3927 argument to m4_foreach. I guess it was necessary in the past,
3928 but I think it's a no-op now.
3930 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3932 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3933 ``cat <<_ACEOF'' commands to one.
3934 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3935 * lib/autoconf/status.m4: On various places, use expr instead of
3936 ``echo|sed.''
3937 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3938 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3939 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3940 a range.
3941 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
3942 the wrong patterns between ``case'' and ``esac.'' The previous
3943 code had false positives.
3945 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
3947 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3948 as on 2005-05-02.
3949 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

4012 quoting rules. Problems noted by Stepan Kasal.
4013 Also, throughout this document, be more careful about white space.
4014 "blank", "white space", and "space" all have different meanings
4015 and we should be careful to say what we mean.

4069 (m4_strip): Update the explanation.
4071 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>

4076 * lib/autoconf/functions.m4
4077 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4078 Don't bother to remove core files; AC_RUN_IFELSE should do that
4079 for you.

4100 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
4102 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
4103 as well as configure.in. Problem reported by Gregorio Guidi.
4105 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
4107 * doc/autoconf.texi (Particular Functions): Use gnulib's current

4121 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
4123 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4125 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4126 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4127 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4128 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4129 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4131 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4133 * NEWS: The configure command now warns you if you attempt to use
4134 a directory whose name contains a special character like space,
4135 newline, or "\".
4136 * doc/autoconf.texi (Installation Directory Variables): Allow
4137 "," in file names. Do not use \@; it's not a portable regexp.
4138 * bin/Makefile.am (edit): Likewise.
4139 * lib/Makefile.am (edit): Likewise.
4140 * tests/Makefile.am (edit): Likewise.

4146 unportable file names.
4147 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4148 (AC_INIT): Use it.
4149 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4150 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4151 ac_pwd, and quote srcdir.
4152 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4154 * doc/autoconf.texi: Fix some systematic formatting problems.
4155 ".)" needs a following @: if not at the end of a sentence, and
4156 similarly for "!)". "etc." should be preceded by a comma.
4157 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4159 2005-03-22 Bruno Haible <bruno@clisp.org>
4161 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4162 argument is often called 'build-aux'.
4164 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4166 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4167 macro AC_TRY_LINK is obsolete.
4168 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4169 `AC_CONFIG_FILES'.
4171 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4173 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4174 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4175 from a Common Lisp's `cl'.
4176 (AC_PROG_CXX): Behave according to the documentation: don't
4177 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4178 make the variable CCC precious; use `cl.exe', not `cl'.
4180 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4181 Alexandre Duret-Lutz <adl@gnu.org>
4183 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4184 /dev/null, as "configure" shouldn't read stdin, and this insulates
4185 us from problems (e.g., when testing for "cl"). Also, do this
4186 redirection before invoking "hostname" or "uname", and keep the
4187 original input stream available via...
4188 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4189 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4190 bother with "</dev/null" since it's now done at the top of
4191 'configure'.
4192 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4193 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

4199 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4201 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4202 newline if neither \c nor -n work, as that would output two
4203 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4205 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4207 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4208 This causes that any required macros inside will get before the if.
4209 * doc/autoconf.texi (autom4te.cache): A typo.
4211 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4213 Undo previous change, except keep the change to
4214 lib/autoconf/programs.m4 that replaced grep with shell
4215 pattern-matching. This is because net-snmp configure reads stdin.
4216 Reported by Noah Misch.
4218 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4220 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4221 from /dev/null, as "configure" shouldn't read stdin, and this
4222 insulates us from problems (e.g., when testing for "cl").
4223 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4224 before invoking "hostname" or "uname".
4225 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4226 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4227 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4228 "</dev/null" since it's now done at the top of 'configure'.
4229 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4230 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4231 Also, replace grep with shell pattern-matching, to save a process.
4233 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4235 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4236 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4237 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4238 compiler.
4240 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4242 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4243 grep -q isn't portable. Improve grep -s explanation.
4244 Problem reported by Dan Manthey.
4246 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4248 * doc/autoconf.texi (Special Shell Variables): Clarify
4249 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4251 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4253 * doc/autoconf.texi: Use @acronym for DJGPP.
4254 Fix some @code's that should have been @env's, and vice versa.
4255 Sort environment variable names.
4256 Mention that shells no longer inherit IFS.
4257 Don't recommend PATH_SEPARATOR=';' so strongly.
4258 Mention that $RANDOM might expand to the empty string.
4259 "symlink" and "soft link" -> "symbolic link".
4260 Improve mktemp description (reported by Bruno Haible).
4262 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
4264 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
4265 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
4266 Likewise.

4272 * NEWS: Mention AT_COPYRIGHT.
4274 * tests/local.at (AT_CMP): Use diff directly on input files rather
4275 than copying them.
4277 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
4278 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).

4291 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
4292 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.

4296 excess test name quoting.
4297 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
4298 CPPFLAGS to `configure' instead of setting it in `configure'.
4300 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
4301 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
4302 on some platforms.
4304 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):

4333 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
4335 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
4336 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4338 Try not to generated lines of unlimited length, as POSIX places a
4339 2047-byte limit on line length of portable text files.
4340 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
4341 Use newline as a separator, not space.

4343 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
4344 space.
4346 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4348 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to

4350 are restored after function return.
4352 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
4354 * doc/autoconf.texi (Special Shell Variables): Mention _,
4355 BIN_SH, DUALCASE. Say that variables other than "status" are safe
4356 if they contain a lower-case letter. The DUALCASE problem was
4357 reported by Ralf Wildenhues.
4359 * bin/autoconf.as: Don't exit with status 0 after write failure
4360 with --help or --version.

4372 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
4374 * man/Makefile.am (.x.1): Go back to the simple solution, but take
4375 care to echo the commands, so the user knows what's going on.
4376 Modified from a suggestion by Stepan Kasal.
4378 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

4399 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4400 Update the long comment explaining it.
4402 m4_require no longer writes an ``is required by'' line to the
4403 execution stack. It contains only one bit of non-redundant
4404 information: that the macro was required, not called. And even
4405 this bit is useless in most situations: have you ever met a macro
4406 which both calls and requires the same macro?
4408 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4409 (_m4_defun_pro_outer): ... only via this macro, for the outermost
4410 macro.
4411 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
4412 (m4_expansion_stack_pop): Remove the misplaced comment.
4413 (m4_require): Don't put the ``is required by'' line to the
4414 execution stack; slightly improve the out-of-a-defun error message.
4415 (_m4_divert_grow): New macro, counter for the temporary diversions.
4416 (_m4_require_call): Use it.
4417 * tests/m4sugar.at (m4_require): Expect output without the
4418 ``is required by'' messages.
4420 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4422 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4423 rather than x for expr.
4425 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
4426 this is safe.
4427 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

4439 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
4440 from masters, so that FileUtils.pm's update_file provide --force
4441 support.
4442 * bin/autoheader.in: Pass $force to update_file so that
4443 config.h.in is always recreated when --force.
4445 2005-01-24 Stepan Kasal <kasal@ucw.cz>
4447 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
4449 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
4451 * doc/autoconf.texi (Limitations of Builtins): Clarify that
4452 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
4454 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
4456 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
4457 Warn about newline stripping in `` and $(). Update Solaris
4458 version to 9.
4459 (Limitations of Builtins): Use expr "X...", not expr "x...", as
4460 X insulates us from future changes to Posix.
4461 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
4462 stripping.
4464 2005-01-19 Stepan Kasal <kasal@ucw.cz>

4482 ulongval to be static, to avoid unwanted GCC warning. Problem
4483 reported by Michael Jennings via Daniel Reed; see
4484 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
4486 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
4488 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

4490 datadir, infodir, and mandir. Adjust argument parsing code.
4491 (_AC_INIT_HELP): Update help text.

4493 new variables.
4495 2005-01-04 Noah Misch <noah@cs.caltech.edu>
4497 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
4498 not seem to work, assume it does set $(MAKE).
4499 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
4501 2005-01-03 Stepan Kasal <kasal@ucw.cz>
4503 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.
4505 2005-01-03 Stepan Kasal <kasal@ucw.cz>
4507 A cleanup of the diversion support in m4sugar.
4509 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
4510 (_m4_divert_n_stack): New macro; the expansion is
4511 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
4512 otherwise.
4513 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
4514 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
4515 stored in _m4_divert_diversion or _m4_divert_dump.
4516 (m4_divert_pop): When the parameter is given, compare the symbolic
4517 name with the last diversion pushed on the stack. Previously, the
4518 current diversion was compared with the numeric value of the
4519 diversion given as the parameter.
4520 (m4_require): If the macro hasn't been expanded yet, call ...

4828 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4829 "char c = '\200';" rather than "char c = 0x80;" as the

4991 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
4993 * config/config.guess, config/config.sub, config/elisp-comp,
4994 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
4995 doc/fdl.texi, doc/standards.texi: Sync with master copy.
4997 * NEWS, TODO, configure.ac, bin/autoscan.in,
4998 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
4999 doc/install.texi, lib/Autom4te/Configure_ac.pm,

5004 tests/tools.at, tests/torture.at:
5005 Use "file name" rather than "filename" or "path",
5006 to be consistent with the terminology of the GNU coding standards.
5008 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5010 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5011 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5012 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5013 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5015 More fixes to support spaces in the name of the build directory.
5016 This isn't a complete fix but it's an improvement.
5018 * bin/autoconf.as (autom4te_options): New var.
5019 Use it instead of appending to AUTOM4TE, so that we can allow
5020 spaces in the build directory's absolute name.
5021 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5022 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
5023 AT_CHECK_NOESCAPE): Likewise.
5024 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
5025 main program): Likewise.
5027 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
5029 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
5030 From Ralf Corsepius in:
5031 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
5033 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
5035 * doc/autoconf.texi (Function Portability): Document isinf and
5036 and isnan. From a suggestion by Kevin Ryde.
5038 * lib/Autom4te/General.pm (END): Return correct exit status even
5039 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5041 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5043 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5044 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5045 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5047 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5049 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5050 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5051 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5052 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5053 * lib/autom4te.in (Automake-preselections): Preselect
5054 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5056 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5058 * lib/autom4te.in (Automake-preselections): Preselect
5059 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5060 trace them.
5062 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5064 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5065 Tru64.
5066 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5067 Document problem with "`""`" in pdksh POSIX mode.
5069 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5071 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5072 with pdksh, too. Problem reported by Patrick Welche via
5073 Gary V. Vaughan.
5074 * doc/autoconf.texi (Shellology): Note that set -o posix is
5075 useful for pkdsh, too.
5077 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5079 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5080 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5081 Don't fail if ENV or BASH_ENV is readonly.
5082 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5083 etc. are read only. Problem reported by Ludovic Courtes.
5085 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5087 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5088 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5089 (trivial change)
5091 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5093 * doc/autoconf.texi (File System Conventions): Warn about
5094 names like "aux". Problem reported by Eric Blake.
5096 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5097 by zero instead of array size, so that we can use any arithmetic
5098 constant expression (instead of requiring an integer constant
5099 expression). This allows us to test expressions like DBL_MAX <
5100 LDBL_MAX, which didn't conform to the C standard using the old
5101 method.
5102 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5103 now that we can do floating-point tests at compile time.
5105 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5107 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5108 and LDBL_EPSILON, as the resulting expression isn't an
5109 integer constant expression and violates the C standard.
5110 Problem reported by Nelson H. F. Beebe. Also, check
5111 for "L" suffix, and check that long double doesn't have
5112 worse range or precision than double, that mixed-mode
5113 arithmetic doesn't generate a diagnostic, that double
5114 constants fit in long double.
5116 2004-06-03 Kevin Ryde <user42@zip.com.au>
5118 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5119 malloc(0) and realloc(NULL,size).
5121 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5122 Bob Proulx.
5124 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5126 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5127 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5128 by Jim Meyering.
5130 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5132 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5133 can be rewritten using if-then-else. Suggested by Bruno Haible.
5135 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5137 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5138 Problem reported by Stepan Kasal.
5140 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5142 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5143 change). Patch reported by Ralf Wildenhues in
5144 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5146 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5147 function F exists if the compiler and linker let you compile an
5148 expression like (F != 0). Recent versions of GCC optimize away
5149 the reference to F in that case, since every function address must
5150 be nonzero, so the link succeeds even if F does not exist.
5151 Problem reported by Manu in
5152 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5154 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5155 "Unix". Many uses changed.
5156 (Limitations of Builtins): Explain better why the ! command isn't
5157 portable.
5159 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5161 * lib/autom4te.in (Automake-preselections): Preselect
5162 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5164 2004-05-19 Kevin Ryde <user42@zip.com.au>
5166 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5167 referencing AC_FUNC_STRERROR_R.
5169 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5170 note pessimistic assumption when cross compiling.
5172 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5174 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5175 (until 2004) invoked subcommands with sh -e, contra POSIX.
5176 Reported by Kevin Ryde.
5178 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5180 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5181 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5182 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5183 `test -f " /usr/bin/grep"', which _always_ failed.
5184 (AC_PROG_SED): Ditto bogus PATH fix.
5185 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5186 requires that grep correctly supports _multiple_ `-e' options, rather
5187 than stating only that grep should accept `-e'.
5189 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5191 Port to C99, which requires that 'exit' be declared.
5193 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5194 to ensure that stdlib.h is included.
5195 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5196 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5197 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5198 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5199 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5200 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5201 when using 'exit' in a test; C99 requires that 'exit' be declared.
5203 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5205 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5206 now prefers 'grep' implementations that accept -e.
5207 (Limitations of Usual Tools): Describe problems of traditional
5208 egrep and fgrep with long input lines, and of traditional grep
5209 with -e.
5210 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5211 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5212 All callers changed. Append /usr/xpg4/bin to the PATH, for
5213 Solaris.
5214 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5215 the user with complaints about multiple -e options.
5216 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5217 Define it with AC_PROG_GREP.
5218 * configure.ac (AC_PROG_GREP): Add.
5219 * lib/freeze.mk (GREP): New macro.
5221 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5223 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5224 a possible candidate only after all others fail, rather than
5225 consulting it first. This improves backward compatibility by
5226 better reflecting the way shell selection occurred in previous
5227 versions of Autoconf, and should help to avoid triggering latent
5228 problems in other packages, such as the one in Automake where zsh
5229 is not handled robustly:
5230 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5231 Although it is not Autoconf's responsibility to work around
5232 problems in Automake, it nevertheless makes sense to avoid
5233 introducing unnecessary incompatibilites.
5235 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5236 Gary V. Vaughan <gary@gnu.org>
5238 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5239 how deeply nested we are when a suitable tool is found, set the
5240 ac_path_TOOL_found flag.
5241 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5242 nested we are in this macro. Break out of all 3 nested loops if
5243 ac_path_TOOL_found is set.
5245 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5247 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5248 of the _AS_PATH_WALK loop too if GNU flavor is found.
5250 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5252 * doc/autoconf.texi (Limitations of Make): Update documentation
5253 for `$<'. New entry `Long lines', based on a report from Simon
5254 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5255 paragraph about DJGPP, based on a mail from Richard Dawe.
5257 2004-04-20 Paul Eggert <eggert@twinsun.com>
5259 * tests/c.at (C keywords): Don't assume that GCC supports
5260 "restrict" and "inline", as sufficiently-old GCC versions do not
5261 (also, GCC configured to be in pedantic C89 mode does not).
5262 Problem reported by Sumit Pandya in:
5263 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5265 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5266 consider -g to work if it generates warnings when plain compiles
5267 don't. Problem reported by Braden McDaniel in:
5268 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5270 * doc/autoconf.texi (Slashes): New section, to document a problem
5271 reported by Jim Meyering in:
5272 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5274 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5275 linker output files before linking, to work around IRIX 6 linker bug.
5276 Problem reported by Rainer Orth in:
5277 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5279 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5281 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5282 best tool so far counter rely on the tool path variable name to
5283 avoid checks for one tool being affected by the results of running
5284 the length check on a previous tool.
5286 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5287 match expression argument, as different greps have different
5288 regular expression flavours.
5289 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5290 literals.
5291 (AC_PROG_EGREP): Pass 'EGREP$'.
5292 (AC_PROG_GREP): Pass 'GREP$'.
5294 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
5296 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
5297 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
5299 2004-03-29 Paul Eggert <eggert@twinsun.com>
5301 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
5302 Types, Specific Compiler Characteristics, System Services,
5303 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5304 etc. consistently instead of 'long', 'short', 'unsigned' etc.
5305 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
5306 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
5307 Likewise.
5308 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
5309 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
5310 AC_TYPE_OFF_T): Likewise.
5311 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
5312 Likewise.
5314 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
5315 pacify libtool 1.5.2. Fix quoting problems in sed command.
5317 2004-03-28 Paul Eggert <eggert@twinsun.com>
5319 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
5320 now defines HAVE_DECL_TZNAME if it is declared, when
5321 HAVE_STRUCT_TM_TM_ZONE is not defined.
5322 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5323 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
5324 for HAVE_TZNAME.
5326 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
5328 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
5329 superfluous backslashing of quotes (") in sed expressions;
5330 thanks to Paul Eggert.
5332 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
5334 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
5335 Fortran compiler is ifort, also added pghpf; thanks to Nelson
5336 H. F. Beebe for the bug report.
5338 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
5340 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
5341 quoted -cmdline argument in Portland Group compiler (bug
5342 reported by Jeffrey J. Barteet).
5344 2004-03-25 Kevin Ryde <user42@zip.com.au>
5346 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
5347 (Run Time): ... here, where it's now mentioned.
5349 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
5351 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
5352 inherits from language Autoconf-without-aclocal-m4.
5353 (Customizing autom4te): Adjust example; the cache must now be
5354 disabled for language Autoconf-without-aclocal-m4.
5356 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
5357 Nathanael Nerode <neroden@twcny.rr.com>
5359 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
5360 AC_CHECK_TOOLS): Warn if a cross-tool is found without
5361 a prefix.
5362 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
5363 AC_CHECK_TARGET_TOOLS): New macros.
5364 * doc/autoconf.texi (Generic Programs): Document
5365 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
5366 AC_CHECK_TARGET_TOOLS, and warn for future changes
5367 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
5368 AC_CHECK_TOOLS.
5369 (Specifying Names): Document the reason for these future
5370 behavioral changes.
5371 * tests/mktests.sh: Do not generate tests for the
5372 new macros.
5373 * NEWS: Document these changes.
5375 * doc/autoconf.texi: Avoid macros with unbraced arguments,
5376 they make TeX hang up.
5378 2004-03-15 Paul Eggert <eggert@bogus.example.com>
5380 * NEWS: New macro AC_CHECK_ALIGNOF.
5381 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5382 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
5383 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
5384 vowel.
5385 (AC_CHECK_ALIGNOF): New macro.
5386 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
5387 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
5388 those for sizeof.
5390 2004-03-03 Paul Eggert <eggert@twinsun.com>
5392 * bin/Makefile.am (edit): Don't use $< in a context where
5393 POSIX doesn't require support for it. Use $@.in instead.
5394 Problem reported by Anthony N. Frasso in
5395 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
5396 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
5398 2004-02-23 Gary V. Vaughan <gary@gnu.org>
5400 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
5401 from the next generation of Libtool.
5402 * lib/autom4te.in (Autoreconf-preselections): Ditto.
5404 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5406 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
5407 is not always thread-safe. Report from Nathanael Nerode.
5409 2004-02-18 Paul Eggert <eggert@twinsun.com>
5411 Fix a dependencies problem, stemming from a Autoconf 2.59 build
5412 problem on QNX reported by Stephen Rasku in
5413 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
5415 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
5416 $(m4sh_m4f_dependencies); this removes a FIXME.
5417 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
5418 (MAINTAINERCLEANFILES): Split into pieces,
5419 one per related section. Add $(srcdir)/wrapper.in.
5421 2004-02-09 Paul Eggert <eggert@twinsun.com>
5423 * doc/autoconf.texi (Setting Output Variables): Emphasize that
5424 AC_SUBST provides no portable way to escape literal newlines.
5426 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5427 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5428 Darwin uses -lcrt2.o and there's little point to cataloging all

5461 (_AS_SHELL_FN_SPY): New macro.
5462 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New

5469 (AS_REQUIRE_SHELL_FN): Require shell functions when
5470 it is used.
5471 (_AS_LINENO_WORKS): Put around braces, we do not

5505 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

5507 the 2003-05-22 change, which removed the older years from the list.
5508 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
5510 2004-01-27 Gary V. Vaughan <gary@gnu.org>

5528 2004-01-27 Paul Eggert <eggert@twinsun.com>
5530 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

5532 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
5533 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
5535 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
5536 bin/autoconf.in, config/Makefile.in, config/config.guess,
5537 config/config.sub, config/install-sh, config/mdate-sh,

5552 2004-01-26 Paul Eggert <eggert@twinsun.com>
5554 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
5555 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
5556 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
5557 not <inttypes.h>. Problem reported by Tim Mooney in
5558 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
5559 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
5560 Likewise.
5562 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
5563 otherwise "make check" fails because it forbids cmp (I guess
5564 because cmp treats files as binary on DOS-like systems).
5566 * tests/mktests.sh: Update copyright date to 2004, since some tests
5567 have changed in 2004.
5569 2004-01-23 Gary V. Vaughan <gary@gnu.org>

5572 non-truncating sed or gsed program in PATH.
5573 * tests/acprograms.at: Add it.
5574 * doc/autoconf.texi (Particular Programs): Document it.
5575 * NEWS: Updated.
5577 2004-01-15 Paul Eggert <eggert@twinsun.com>
5579 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
5580 -std1 disables some useful extensions on Tru64. Problem reported
5581 by N. Lichtmaier in
5582 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
5584 2004-01-14 Paul Eggert <eggert@twinsun.com>
5586 * doc/autoconf.texi (Programming in M4sh): Document that
5587 AS_MKDIR_P succeeds if the destination is a symbolic link
5588 to an existing directory.
5589 (Limitations of Usual Tools): Note that mkdir -p might not
5590 succeed on symlinks to directories.
5592 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
5594 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
5595 * bin/autoheader.in: Grammar fix in message.
5596 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
5597 Test for dir before calling mkdir -p. (trivial changes)
5599 2004-01-13 Eric Blake <ebb9@byu.net>
5601 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
5602 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
5604 2004-01-10 Jim Meyering <jim@meyering.net>
5606 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
5608 2004-01-09 Paul Eggert <eggert@twinsun.com>
5610 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
5611 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
5612 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
5613 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
5614 AC_COMPILE_IFELSE, since we now assume our caller invokes
5615 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
5616 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
5617 of AC_RUN_IFELSE; this avoids the warning mentioned above.
5618 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
5620 2004-01-07 Paul Eggert <eggert@twinsun.com>
5622 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
5623 `"'...'"`, as it's confusing (and I suspect it may not work on
5624 some platforms). The code was incorrect anyway, as it assumed
5625 that \$ evaluated to itself in that context. Reported by
5626 Alexandre Duret-Lutz.
5628 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
5630 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

5635 * doc/autoconf.texi (One Macro Call): Fix an incorrect
5636 example, and add more examples. Reported by Eric Sunshine.
5638 2004-01-05 Paul Eggert <eggert@twinsun.com>
5640 * doc/autoconf.texi (Limitations of Usual Tools):
5641 Remove warning against "rm -fr" introduced yesterday; it
5642 was a false alarm.
5644 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
5645 autoscan, autoupdate, ifnames): Don't use chmod -w.
5646 * lib/Makefile.am (autom4te.cfg): Likewise.
5647 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
5648 "chmod -w".
5650 2004-01-04 Paul Eggert <eggert@twinsun.com>
5651 Paolo Bonzini <bonzini@gnu.org>
5653 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
5654 by doing lineno substitution only on lines containing "$LINENO".

5658 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
5659 Use "rm -f" to remove conftest.sed, not plain "rm".
5660 Bug reported by David Relson in
5661 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
5663 * Makefile.am (autom4te-update):
5664 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
5665 * Makefile.maint (my-distcheck, do-po-update): Likewise.
5666 * doc/autoconf.texi (Guidelines): Likewise.
5667 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

5672 * tests/Makefile.am (clean-local): Likewise.
5673 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
5674 srcdir): Likewise.
5675 * doc/autoconf.texi (Limitations of Usual Tools):
5676 Warn against "rm -fr".
5678 2004-01-03 Paul Eggert <eggert@twinsun.com>
5680 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
5681 -c -o might not work. From a suggestion by Kevin Ryde.
5682 (C Compiler, Generating Sources, Limitations
5683 of Usual Tools, Limitations of Make, Making testsuite Scripts):
5684 Don't put '-o' after non-options, as POSIX doesn't allow this.
5685 Mention that cc's name might be gcc or c89 or whatever.
5687 2004-01-04 Kevin Ryde <user42@zip.com.au>
5689 * doc/autoconf.texi: Add various further index entries.
5691 2003-12-29 Paul Eggert <eggert@twinsun.com>
5693 * bin/autoreconf.in (autoreconf_current_directory):
5694 Fix typo: mkdir without umask arg.
5696 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
5698 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
5699 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
5700 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
5701 explanation clearer.
5703 2003-12-24 Andreas Schwab <schwab@suse.de>
5705 * doc/autoconf.texi (Default Includes): Fix misspelling of
5706 AC_INCLUDES_DEFAULT.

5710 * configure.ac: Test if sh -n works.
5711 * configure: Regenerate.
5712 * tests/atlocal.in: Store the result here.
5713 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
5714 tools.at, looking in atlocal's ac_cv_sh_n_works instead
5715 of explicitly testing.
5716 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
5717 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
5718 * tests/tools.at (Syntax of the shell scripts): Simplify
5719 using AT_CHECK_SHELL_SYNTAX.

5732 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
5733 Extracted from AS_SHELL_SANITIZE.
5734 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
5735 macros.
5736 (AS_SHELL_SANITIZE): Move reinvocation code from
5737 _AS_LINENO_WORKS, use it to find out if shell
5738 functions work.
5739 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
5740 does not work.
5741 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
5742 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

5760 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

5797 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes

5803 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
5804 than $target since the latter is not usual, add guidelines on when to
5805 use or not use the system type.
5807 2003-11-12 Derek Price <derek@ximbiot.com>
5809 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

5964 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
5965 cross test.
5967 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
5969 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
5970 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

5981 Issue a more-informative diagnostic.
5982 Problems reported by Eric Sunshine.
5984 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5986 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
5987 -mGLOB_options_string stuff for Intel ifc, which can cause

5997 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
5998 that future autopoint/aclocal/automake/autoreconf will be able
5999 to trace to find where to install local m4 macros.

6007 -lcrt[01].o.
6009 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
6011 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6012 cache variable instead of $G77 to decide whether to include -O2,
6013 since $G77 is specific to Fortran 77.
6015 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6017 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
6018 free" flag. Re-order flags tested into rough order of popularity.
6020 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6022 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6023 arguments so that it can be used with syntax identical to
6024 AC_PROG_F77, and so that we can more easily decide to
6025 remove/deprecate the DIALECT optional argument in the future if it
6026 proves troublesome.
6027 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
6028 non-freeform-supporting compilers. Document freeform flags.
6030 2003-10-03 Akim Demaille <akim@epita.fr>
6032 * configure.ac: Look for emacs, not macs.
6033 Reported by Eric Sunshine.
6035 2003-10-03 Akim Demaille <akim@epita.fr>
6037 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
6038 * bin/autoreconf.in (autoreconf_current_directory): Create the
6039 AUX_DIR if needed, for sake of automake --add-missing etc.
6040 Suggested by Alexandre Duret-Lutz.
6042 2003-10-03 Akim Demaille <akim@epita.fr>
6044 * configure.ac: Quotation and formatting changes.

6065 * lib/Autom4te/XFile.pm: Use Errno.
6066 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
6067 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
6069 2003-09-30 Akim Demaille <akim@epita.fr>
6071 * config/announce-gen (&print_news_deltas): Extracted from...
6072 (&print_changelog_deltas): here.

6074 (@news_file): this.
6076 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
6078 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
6079 have been created when invoking the compiler.

6091 Problem reported by Lars J. Aas in
6092 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
6093 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6094 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6095 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6097 2003-09-26 Akim Demaille <akim@epita.fr>
6099 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6100 directory for AC_CONFIG_COMMANDS' first argument exists.
6101 This makes valid the invocation of _AC_SRCPATH that follows.
6102 Reported by Eric Sunshine.
6103 * doc/autoconf.texi (Configuration Commands): Adjust.
6105 2003-09-26 Akim Demaille <akim@epita.fr>
6107 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6108 Reported by Ralf Corsepius.
6110 2003-09-26 Akim Demaille <akim@epita.fr>
6112 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6113 arguments.
6114 Actually, use AU_ALIAS.
6115 From Bruno Haible.
6117 2003-09-26 Paul Eggert <eggert@twinsun.com>
6119 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
6120 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.

6124 2003-09-26 Akim Demaille <akim@epita.fr>
6126 The test suite are sometimes assigning timings incorrectly.
6127 Reported by Henk Krus.
6128 Diagnosed by Nicolas Joly.
6130 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6131 AT_help_all.
6132 Instead of making AT_help a sequence of assignments to grow
6133 $at_help_all, just make AT_help_all be the growing contents of
6134 $at_help_all, and make a single assignment in...
6135 (AT_INIT): here.
6136 (at_times_skip): Flip the meaning and rename as...
6137 (at_times_p): this.
6138 (AT_INIT): When summarizing the test that ran, remove
6139 $at_times_file after use, and check it is present before trying to
6140 use it.
6142 2003-09-25 Akim Demaille <akim@epita.fr>
6144 Version 2.57d.
6146 * bin/Makefile.am (edit): Handle '@configure_input@'.
6147 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6148 (ifnames): chmod -w.
6149 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6150 executables, not bin/ executables! Otherwise all the magic needed
6151 to find non installed files is turned off. This caused a failure
6152 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6153 as found in its environment (sent by tests/autoreconf): pointing
6154 to bin/autom4te that could not find its files.
6155 * tests/mktests.sh: Force the replacement of generated files, for
6156 the sake of "mv" program that are interactive when overwriting a
6157 -w file.
6158 * config/install-sh: Upgrade from CVS Automake.
6160 2003-09-23 Paul Eggert <eggert@twinsun.com>
6162 * doc/autoconf.texi (Limitations of Builtins): Document test -h
6163 versus test -L issues.
6165 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
6166 Paul Eggert <eggert@twinsun.com>
6168 Trivial change to support GCC's configuration procedure.
6169 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6170 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6171 about inconsistency if the preprocessor is set to give errors for
6172 any warning.
6173 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6175 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
6177 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
6178 and XFile.pm from Automake.

6193 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
6194 not asm/types.h.
6196 2003-09-11 Akim Demaille <akim@epita.fr>
6198 * doc/autoconf.texi (Header Portability): linux/random.h.
6199 From Peter Hendrickson.
6201 2003-09-10 Akim Demaille <akim@epita.fr>
6203 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6204 willing to edit the output files.
6206 2003-09-10 Akim Demaille <akim@epita.fr>
6208 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6209 and AC_FC_FREEFORM.
6210 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6211 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
6213 2003-09-09 Akim Demaille <akim@epita.fr>
6215 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.

6226 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
6227 Improve the accuracy of the wording about obsolescence.
6228 From a suggestion by Ian Lance Taylor in
6229 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
6231 2003-09-05 Paul Eggert <eggert@twinsun.com>
6233 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6234 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6236 2003-09-04 Akim Demaille <akim@epita.fr>
6238 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6239 AC_FUNC_WAIT3.
6241 2003-09-04 Akim Demaille <akim@epita.fr>
6243 * bin/autom4te.in: Use &fatal where more appropriate than &error.
6244 (freeze): When exiting, use $exit_code.
6245 * lib/autoconf/fortran.m4: Comment changes.
6247 2003-09-04 Akim Demaille <akim@epita.fr>
6249 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
6251 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6253 Add support for newer Fortran dialects. The F77 interface is
6254 unchanged, and continues to support Fortran 77. New FC macros
6255 correspond to all the old F77 macros, with output variables FC,
6256 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6257 available dialect, but older dialects can be specified. There are
6258 new macros AC_FC_SRCEXT to set the source extension, and
6259 AC_FC_FREEFORM to accept free-form source files.
6261 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
6262 New macros.
6263 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
6264 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
6265 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
6266 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

6278 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
6279 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
6280 Rewrite in terms of the above.
6281 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
6282 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

6286 2003-09-02 Paul Eggert <eggert@twinsun.com>
6288 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
6289 Document problems with timestamp resolution that 'make', 'cp -p', and
6290 'touch -r' have.
6292 2003-08-27 Akim Demaille <akim@epita.fr>
6294 * tests/m4sugar.at (cross_warning): Make sure to enable the
6295 output, so that we can track spurious m4sugar output.
6296 * tests/local.at: Require 2.57.
6297 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
6298 are defaulted by AT_CHECK anyway.
6299 Use AT_CHECK_AUTOM4TE.
6300 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
6301 missing dnl.
6303 2003-08-27 Akim Demaille <akim@epita.fr>
6305 * bin/autoheader.in: Issue the "Using auxiliary..." message only
6306 when -Wobsolete is set.

6362 2003-08-22 Akim Demaille <akim@epita.fr>
6364 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
6365 * bin/autom4te.in: Adjust.
6367 2003-08-21 Akim Demaille <akim@epita.fr>
6369 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
6370 (&verbose): Remove.
6371 (&getopt): Adjust the note and verb channels, depending upon
6372 --verbose.
6373 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
6374 * bin/autoupdate.in: Adjust.
6375 Use &verb, not &verbose.
6377 2003-08-21 Akim Demaille <akim@epita.fr>
6379 * bin/autoheader.in (&parse_args): Use &parse_warnings and
6380 &parse_WARNINGS.
6381 ($help): Use Autom4te::ChannelDefs::usage.
6382 * bin/autoscan.in: Use Autom4te::ChannelDefs.
6383 * lib/Autom4te/General.pm: Don't export error: you don't own it.
6385 2003-08-21 Akim Demaille <akim@epita.fr>
6387 First stab at preserving warnings between calls to autom4te,
6388 including when the cache is used.
6390 There are still several issues: (i) there are too many runs of m4
6391 (one for include, one for warnings, and some more), (ii) warnings
6392 spreading on several lines are not handled gracefully, (iii) the
6393 code meant to have the call stack display for errors does not work
6394 (its handling should move from m4 to autom4te).
6396 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6397 Use them.
6398 (@preselect): Add m4_warn.
6399 ($exit_status): Remove, use $exit_code.
6400 ($help): Use Autom4te::ChannelDefs::usage.
6401 (&handle_m4): No longer define the m4_warnings.
6402 At each run, extract and report the warnings.
6403 Always cache the result, including if the exit status is on
6404 failure, since if nothing changes, we should result in the same
6405 failure, hence we can use the cache.
6406 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6407 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6408 Remove.
6409 (m4_warn): Redefine as a do-nothing: it is its invocation that
6410 matters, as warnings are now reported via traces.
6411 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6412 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6413 the latter reveals calls to the former.
6415 Adjust the tests.
6417 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6419 2003-08-21 Akim Demaille <akim@epita.fr>
6421 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
6422 Use them.
6424 2003-08-21 Akim Demaille <akim@epita.fr>
6426 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
6427 forward order.
6428 * lib/Autom4te/ChannelDefs.pm: Doc typos.
6429 (&parse_warnings): Accept a list of warning requests.
6430 (&usage): Return a string, not a side effect.
6431 (cross): New warning category.
6433 2003-08-21 Akim Demaille <akim@epita.fr>
6435 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
6436 (&require_configure_ac): Accept an optional directory argument.
6437 ($configure_ac): Remove.
6438 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
6439 (&catfile): Remove.
6440 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
6441 * bin/autoscan.in: Adjust.
6443 2003-08-20 Akim Demaille <akim@epita.fr>
6445 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
6446 Reported by Alexandre Duret-Lutz.
6448 2003-08-20 Akim Demaille <akim@epita.fr>
6450 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
6451 * bin/autom4te: Adjust.
6452 In particular, be Autoconf tools are really silent when properly
6453 working, bind the verbosity of the 'note' channel to $verbose.
6454 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
6455 (&xsystem, &contents): Remove, since they are exported by...
6456 * lib/Autom4te/FileUtils.pm: this.
6457 More perldoc.
6458 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
6459 * lib/Autom4te/FileUtils.pm: here.
6461 2003-08-20 Akim Demaille <akim@epita.fr>
6463 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
6464 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
6465 from CVS Automake.
6467 2003-08-20 Akim Demaille <akim@epita.fr>
6469 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
6470 (autom4te-update): New.
6471 * Makefile.cfg (update): Bind autom4te-update.
6473 2003-08-19 Derek Price <derek@ximbiot.com>

6476 (PARSE_ARGS_BEGIN): New section for option parsing related
6477 initialization.

6485 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
6487 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
6489 * lib/autom4te.in (Automake-preselections): Preselect
6490 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
6491 and m4_sinclude.
6493 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
6495 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...

6497 * doc/autoconf.texi (autom4te Invocation): Mention
6498 Autoconf-without-aclocal-m4.

6503 RUN-IF-PASS optional arguments.

6514 2003-08-14 Derek Price <derek@ximbiot.com>
6516 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
6517 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
6518 shorter column three. Add DESCRIPTION to log file content.
6520 2003-08-13 Derek Price <derek@ximbiot.com>
6522 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
6523 output.
6525 2003-08-12 Derek Price <derek@ximbiot.com>
6527 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
6528 (AT_CHECK_NOESCAPE): Move core functionality to...
6529 (_AT_CHECK): ...this new macro.
6531 2003-08-07 Derek Price <derek@ximbiot.com>
6533 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
6534 (AT_CHECK_NOESCAPE): ...to this new macro.
6536 2003-07-31 Paul Eggert <eggert@twinsun.com>
6538 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
6539 in Bash 2.01. Problem reported by Brian Gough in
6540 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
6542 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
6544 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
6545 -lcrt1.o, for OS X. (trivial change)
6547 2003-07-07 Paul Eggert <eggert@twinsun.com>
6549 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
6550 inside '#ifndef __cplusplus'. Problem reported by
6551 Bob Friesenhahn.
6553 2003-07-06 Bill Clarke <llib@computer.org>
6555 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
6556 'long', not 'int', for benefit of Sun's recent C++ compilers
6557 (trivial change). See:
6558 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
6559 (This really should be 'intptr_t', not 'long', but that would
6560 take more work.)
6562 2003-06-25 Akim Demaille <akim@epita.fr>
6564 * lib/Makefile.am (autom4te.cfg): Make it read only.
6565 Depend on Makefile since it contains substitutions.
6566 From Paolo Bonzini.
6567 * lib/autom4te.in (args): Add local.at? for Autotest args.
6568 This change was made on autom4te.cfg which is generated.
6569 Reported by Raja R. Harinath.
6571 2003-06-25 Akim Demaille <akim@epita.fr>
6573 * doc/autoconf.texi (Header Portability): sys/mount.h.
6574 From Gareth McCaughan.
6576 2003-06-23 Akim Demaille <akim@epita.fr>
6578 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
6579 not all of them. This fixes 1. the fact that when testing
6580 Autoconf there are many many config.log, 2. the incorrect use of
6581 top_srcdir to find config.log.
6582 Don't mix the detailed output of failed test with the summary of
6583 failures. Rather, append detailed log afterwards.
6585 2003-06-23 Akim Demaille <akim@epita.fr>
6587 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
6588 always run: output config.log on $at_group_log.
6590 2003-06-23 Akim Demaille <akim@epita.fr>
6592 * tests/torture.at (#define header templates): Don't use quotes in
6593 C++ comments as it puzzles Emacs' sh font-lock-mode.
6595 2003-06-23 Akim Demaille <akim@epita.fr>
6597 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
6598 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
6599 * tests/atspecific.m4: Rename as...

6602 * tests/local.at: here.
6603 * tests/Makefile.am: Adjust.
6604 * doc/autoconf.texi (testsuite Scripts): Adjust.
6606 2003-06-21 Kevin Ryde <user42@zip.com.au>
6608 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
6609 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
6610 ensuring we add -std1 for full-ANSI.
6612 * doc/autoconf.texi (hdrindex): New macro.
6613 Add index entries for portability of various standard header files.
6615 2003-06-20 Akim Demaille <akim@epita.fr>
6617 * configure.ac: Bump to 2.57b.
6619 2003-06-20 Akim Demaille <akim@epita.fr>
6621 Version 2.57a.
6623 2003-06-20 Akim Demaille <akim@epita.fr>

6626 Reported by Marc Espie as PR/233.
6628 2003-06-20 Akim Demaille <akim@epita.fr>
6630 * lib/autotest/general.m4: Use at_times_file only if used.
6631 From Nicolas Joly.

6635 * config/config.guess, config/config.sub, config/elisp-comp,

6639 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
6641 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
6642 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
6643 (TEST_SCRIPT): New diversion.
6644 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
6645 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
6646 (AT_INIT): Support for expected failures.
6648 2003-06-02 Akim Demaille <akim@epita.fr>
6650 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
6651 changes.
6652 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
6653 Autoconf nor Automake.
6654 (&contents): New, from Automake.
6655 PODify.
6657 2003-05-28 Paul Eggert <eggert@twinsun.com>
6659 * NEWS, doc/autoconf.texi (Particular Functions),
6660 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
6661 is the inverse of localtime.
6663 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
6665 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
6666 (handle_exec_errors): New function. Work around $! being
6667 altered by WEXITSTATUS.
6668 (xqx, xsystem): Use handle_exec_errors.
6670 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
6672 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
6673 Do not call `_exit()', simply modify `$?'.
6674 (xsystem): Reset $! before running system, and check it afterward.
6675 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
6676 63 for version mismatches.
6678 2003-05-23 Akim Demaille <akim@epita.fr>
6680 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
6681 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
6682 the middle of a line).
6683 * lib/m4sugar/m4sugar.m4: Likewise.
6684 Remove useless spaces in comments.
6686 2003-05-23 Akim Demaille <akim@epita.fr>
6688 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
6689 exit 63, so that we (or Automake's "missing") can tell the
6690 difference with a plain failure.
6691 * doc/autoconf.texi (Notices): Adjust.
6693 2003-05-23 Akim Demaille <akim@epita.fr>
6695 * Makefile.am, bin/Makefile.am, config/Makefile.am,
6696 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
6697 White spaces cleanup.
6699 2003-05-22 Jim Meyering <jim@meyering.net>
6700 Paul Eggert <eggert@twinsun.com>
6702 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6703 Remove `#include <stdlib.h>' from the list; we should never
6704 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6705 resulting namespace pollution would cause other tests to fail.
6706 Configure scripts run with some older versions of g++ and HP's
6707 aCC would fail due to such an #include. Problems reported by
6708 Matthew Mueller in <http://bugs.debian.org/120704> and by
6709 Keith Bostic in
6710 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6711 In the test, use the test declaration before including <stdlib.h>,
6712 as that's closer to how it'll be used.
6714 2003-05-23 Akim Demaille <akim@epita.fr>
6716 * doc/autoconf.texi (Header Portability): ucred.h.
6717 From Ian Redfern.
6719 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6721 Overhaul Autotest's logging: generate separate log files
6722 in testsuite.dir/NNN/testsuite.log, and append them to
6723 testsuite.log instead of re-running the test verbosely.
6725 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6726 file descriptor, write 0 to at_status_file instead of setting
6727 at_status=0, initialize some new variables (at_status_file,
6728 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6729 to rerun the tests, instead append the at_group_log to the
6730 at_suite_log when a test fails.
6731 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6732 with the AS_MESSAGE_LOG_FD redirected to stdout.
6733 (AT_CLEANUP): save the output status in $at_status_file
6734 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6735 its original place.
6736 (AT_CHECK): since tests are run with a redirected stdout,
6737 and used to be re-run in verbose mode, turn some $at_verbose
6738 into echo, and don't redirect the output of testing stdout
6739 and stderr.
6741 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6742 the name of the debugging directory and information about
6743 its contents.
6745 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6747 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
6748 parameter.

6821 AC_INCLUDES_DEFAULT.
6823 2003-05-17 Akim Demaille <akim@epita.fr>
6825 * lib/autoconf/specific.m4: Include signal.h and unistd.h.

6860 and truncate.
6862 2003-05-06 Akim Demaille <akim@epita.fr>
6864 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6865 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6866 by aclocal.m4 is changed it might require the importing of another
6867 m4 extension file, i.e., aclocal must be run.
6869 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6870 (&parse_args): Use --force with aclocal if required and supported.
6871 (&autoreconf_current_directory): Use &run_aclocal.

6878 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6879 argument instead of a file name, so that the request file remains
6880 open during the whole autom4te run.
6881 ($icache_file): New.
6882 (&freeze): Lock the $icache_file.
6884 2003-04-29 Derek Price <derek@ximbiot.com>
6886 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6887 seperator with m4_append_uniq(). It doesn't work.
6888 (AT_CLEANUP): Add `;' to end of at_help_all.
6889 (AT_INIT): Allow --keywords to be specified more than once. When
6890 grepping $at_help_all for keywords, use the field and keyword
6891 seperators to ensure a complete keyword match. Alter at_prev handling
6892 to support the new --keywords behavior.
6894 2003-04-27 Karl Berry <karl@freefriends.org>
6896 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6897 align better with others. I also made some of the individual
6898 entries on one line, for brevity and to make it easier for me to
6899 sort my dir-example file in the Texinfo distribution :).

6966 header causes problems.
6968 2003-03-28 Akim Demaille <akim@epita.fr>
6970 * tests/torture.at (Configuring subdirectories): Require aclocal
6971 1.4, otherwise the test fails, as it does support configure.ac.

6974 2003-03-28 Akim Demaille <akim@epita.fr>
6976 * doc/autoconf.texi (C Compiler): `#line' portability.

6982 layout in order to allow scripting around test groups.
6984 2003-03-27 Derek Price <derek@ximbiot.com>

6995 obsolete AC_HELP_STRING.
6996 (AC_HELP_STRING): AU_DEFUN to...
6997 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
6998 * tests/m4sh.at (AS_HELP_STRING): New test.
7000 * tests/acgeneral.at: Regenerated.
7002 2003-03-26 Derek Price <derek@ximbiot.com>
7004 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
7005 sense. Verbosify the diversion definitions comment.

7041 * doc/autoconf.texi (Limitations of Make): Remove the section
7042 about `$<' in inference rules, it was a bogus interpretation of
7043 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
7044 Tru64 make in the "target lookup" section.
7045 (Automake): Automake 1.5+ no longer requires special tools to be
7046 present on the developer's host.
7048 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
7050 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
7051 to a shell that can handle redirection or quoting correctly.

7054 * bin/autom4te.in (BEGIN): Likewise.
7055 * bin/autoreconf.in (BEGIN): Likewise.
7056 * bin/autoscan.in (BEGIN): Likewise.
7057 * bin/autoupdate.in (BEGIN): Likewise.
7058 * bin/ifnames.in (BEGIN): Likewise.
7060 * bin/ifnames.in: Add final newline to help and version messages.
7062 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
7063 to cope with DOS-style absolute paths, when constructing
7064 ${ac_make}.
7066 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
7067 When constructing paths with IFS=:, quote the path. If we're
7068 constructing a DOS-style absolute path, we don't want to split it
7069 on the colon.
7071 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
7072 in description.
7074 2003-02-25 Pavel Roskin <proski@gnu.org>

7082 2002-09-01 patch by replacing "test -n" with "test -z".
7083 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
7084 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
7086 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
7087 to fix a mismatch between example and discussion.
7089 2003-02-24 Kevin Ryde <user42@zip.com.au>
7091 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
7092 format starting with "-".
7094 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7096 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
7097 is not portable inside Makefile.
7099 2003-02-20 Akim Demaille <akim@epita.fr>
7101 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7102 compiler says yeah, but preproc says nope, compiler is right.
7103 Conversely, prompt the reader to send a bug report to the
7104 maintainers of the package, not of Autoconf.
7106 2003-02-20 Klee Dienes <kdienes@apple.com>
7108 * bin/autoreconf.in (autoreconf_current_directory): Properly
7109 handle an empty aclocal.m4.

7114 $ac_prefix_program.
7115 From Larry Jones.
7117 2002-12-23 Paul Eggert <eggert@twinsun.com>
7119 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7120 innocuous variant befor including <limits.h> or <assert.h>. This
7121 works around a bug reported by Albert Chin: HP-UX 11i
7122 (and earlier versions) have a <limits.h> that declares
7123 gettimeofday and many other functions.
7125 2002-12-03 Paul Eggert <eggert@twinsun.com>
7127 Version 2.57.
7129 * NEWS, configure.ac: Update version.
7131 * doc/fdl.texi: Upgrade to FDL version 1.2.
7133 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7134 nontrivially in main's body, so that f's external declaration is
7135 not optimized away in AIX. This should fix the bug reported by
7136 Martin Frydl in
7137 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7139 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7140 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7141 defined, to support freestanding compilers. This should fix the
7142 bug reported by Momchil Velkov in
7143 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7145 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7146 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
7147 obsolete AC_CHECK_TYPE. The missing empty arg was reported

7151 * Makefile.maint (www-gnu): New macro.
7152 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
7153 the location has moved.
7155 2002-12-02 Martin Frydl <martin@systinet.com>
7157 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
7158 \(.*\) match is too long and there is something more to be checked.
7159 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
7161 2002-11-15 Akim Demaille <akim@epita.fr>

7165 * config/install-sh: chmod +x.
7166 From Paul Eggert.
7167 * config/move-if-change: Indenting changes.
7168 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
7169 * configure.ac (AM_INIT_AUTOMAKE): here.
7170 Require 1.7.1.
7172 2002-11-14 Akim Demaille <akim@epita.fr>
7174 Version 2.55.
7176 * config/config.guess, config/config.sub, config/install-sh:
7177 Update from masters.
7179 2002-11-14 Akim Demaille <akim@epita.fr>
7181 * Makefile.maint: Sync with Bison, i.e.:
7182 (po-check): Scan .l and .y files instead of the
7183 .c and the .h files that they generate. This fixes the bug
7184 reported by Tim Van Holder in:
7185 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7186 Look for N_ as well as for _. Try to avoid matching #define for
7187 N_ and _.
7188 From Paul Eggert.
7190 2002-11-14 Akim Demaille <akim@epita.fr>
7192 * doc/autoconf.texi (C Compiler): Compiling several files at once.
7193 From Paul Eggert and Albert Chin-A-Young.
7195 2002-11-14 Akim Demaille <akim@epita.fr>
7197 * doc/autoconf.texi (C Compiler): Solitary backslashes.
7198 From Paul Eggert and Albert Chin-A-Young.
7200 2002-11-14 Kevin Ryde <user42@zip.com.au>
7202 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
7203 than assigning in main, to avoid HP cc +O3 optimizing it away.
7205 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
7207 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
7208 option. Process --recheck after parsing all options. Pass -q
7209 option to configure on --recheck.
7210 (AC_OUTPUT): Pass -q from configure to config.status.
7211 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
7212 arguments to record.
7213 * doc/autoconf.texi (config.status Invocation): Document
7214 config.status -q option.
7216 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
7218 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
7219 Makefile.in if Makefile.am exists.
7220 (output): Strip `.am' from Makefiles. Don't
7221 output AC_CONFIG_FILES if no Makefiles were found.
7223 2002-11-07 Akim Demaille <akim@epita.fr>
7225 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
7226 (local_updates): New.
7227 * Makefile.maint: Update, from CVS Bison.
7228 (local_updates): New.
7230 2002-11-06 Akim Demaille <akim@epita.fr>
7232 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
7233 declaration in extern "C" too.
7234 Reported by Roberto Bagnara.
7236 2002-11-06 Akim Demaille <akim@epita.fr>
7238 * tests/torture.at (Configuring subdirectories): Don't use grep
7239 -w.
7240 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
7241 Reported by Ezra Peisach.
7243 2002-11-05 Akim Demaille <akim@epita.fr>
7245 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7246 Remove.
7247 We _have_ to stop using the old compatibility scheme that tried to
7248 avoid useless backslashes because Libtool 1.4.3 contains a
7249 AC_DEFINE([error_t], [int],
7250 [Define to a type to use for \`error_t' if it is not
7251 otherwise available.])
7252 We _have_ to quote the single quote and backslashes with \. The
7253 old compatibility scheme saw that ` was backslashed, and therefore
7254 did not quote the single quote. Hence before this patch, Autoconf
7255 was not compatible with Libtool.
7257 2002-11-04 Paul Eggert <eggert@twinsun.com>
7259 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
7260 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
7261 LC_NAME, LC_PAPER, LC_TELEPHONE.

7264 2002-11-04 Akim Demaille <akim@epita.fr>
7266 Version 2.54c.
7268 * Makefile.maint (update, cvs-update, po-update, do-po-update):
7269 New.
7270 * config/texinfo.tex: Update.
7272 2002-11-03 Akim Demaille <akim@epita.fr>
7274 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
7275 from...
7276 (&autoreconf): here.
7277 ($help, $make, &parse_args, &autoreconf_current_directory):
7278 Support -m/--make.
7279 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7281 2002-10-31 Bruno Haible <bruno@clisp.org>
7283 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.

7288 (AC_FUNC_REALLOC): Change description of HAVE_REALLOC macro.
7290 2002-10-31 Akim Demaille <akim@epita.fr>
7292 The test suite was no longer checking for trailing envvars and files.
7294 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
7295 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
7297 2002-10-31 Akim Demaille <akim@epita.fr>
7299 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
7300 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
7301 Make variable, not a shell variable.
7302 Suggested by Bruno Haible.
7304 2002-10-31 Akim Demaille <akim@epita.fr>
7306 * bin/autom4te.in (load_configuration): Reject #args out of any
7307 language.
7309 2002-10-31 Akim Demaille <akim@epita.fr>
7311 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
7312 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
7313 (_AC_RUN_IFELSE): Use it.
7314 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
7315 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
7316 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
7317 inline it.
7319 2002-10-30 Akim Demaille <akim@epita.fr>
7321 * bin/autom4te.in (&parse_args, $help): Support --no-cache.
7322 * doc/autoconf.texi (autom4te Invocation): Adjust.
7323 Suggested by Tim van Holder.
7325 2002-10-29 Paul Eggert <eggert@twinsun.com>
7327 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
7328 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
7329 Problem reported by Bruno Haible.
7331 2002-10-29 Akim Demaille <akim@epita.fr>
7333 * doc/autoconf.texi (Header Templates): Put also in words what the
7334 pictures says to assist free style readers.
7335 (Customizing autom4te): s/--cache=/--cache /.

7353 * tests/torture.at (Deep Package): New test.

7587 2002-10-22 Akim Demaille <akim@epita.fr>
7589 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

7592 Quote for Perl '' strings, not "".
7593 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
7594 strings.
7596 2002-10-22 Akim Demaille <akim@epita.fr>
7598 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

7645 longer required can still cause errors.
7646 Reported by Alexandre Duret-Lutz.
7648 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
7649 to frozen files in @ARGV, as @ARGV must remain being a list of
7650 files. Rather, at M4 call sites, use this...
7651 (&files_to_options): New function.
7652 (&freeze): Use &error.
7653 (&up_to_date): If a file that was included according to the cache
7654 is no longer there, then the output is out dated.
7655 (&main): Don't even check whether a file is up to date is anyway
7656 --force is given.
7657 * tests/tools.at (autom4te cache): New.
7659 2002-10-16 Akim Demaille <akim@epita.fr>

7663 * bin/autoreconf.in (&parse_args): Remove dead options.
7664 Factor some code.
7665 (&autoreconf): Report the directories we enter *and leave*, so
7666 that error messages can be easily located, and use GNU Make
7667 format, so that Emacs' compile mode understands us.
7668 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
7669 if some file was changed instead of `print'.
7670 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

7683 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
7684 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

7704 file name to enable parallel executions.
7705 From Sam Varshavchik.
7707 2002-10-08 Akim Demaille <akim@epita.fr>
7709 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7710 aclocal invocation, as Gettext macros might not be visible to
7711 aclocal.
7712 Instead of blindly running autopoint, scan configure.ac (not the
7713 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
7714 Reported by Paul D. Smith.
7716 2002-10-08 Paul Eggert <eggert@twinsun.com>
7718 Work around problems found when POSIXLY_CORRECT=1 is set.
7719 None of this seems to have anything to do with POSIX, really,
7720 but it's how Perl getopt works.
7721 * bin/autom4te.in (parse_args): Configure GetOpt with
7722 "permute", too.
7723 * doc/autoconf.texi (Invoking autom4te):
7724 --warning -> --warnings.

7744 2002-09-28 Akim Demaille <akim@epita.fr>
7746 * tests/torture.at (Configuring subdirectories): Be robust to
7747 users who use config.site to require for a cache: in this case,
7748 the two last configure runs, using two different sets of
7749 arguments, trigger a legitimate error.
7751 2002-09-28 Akim Demaille <akim@epita.fr>

7767 (tm_zone): Move their rules to...
7768 * lib/autoconf/types.m4: here, using AN_ macros.
7769 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
7770 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7771 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
7772 * lib/autoconf/programs.m4: here.

7784 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
7785 (.m4.m4f): Don't pass --prepend-include, since that's done by
7786 tests/autom4te itself.
7787 * lib/autoscan/Makefile.am: Include freeze.mk.
7788 (autoscan.list): New target --this file is no longer a source.
7789 (autoscan.pre): New file.
7791 2002-09-28 Akim Demaille <akim@epita.fr>
7793 * bin/autoscan.in (@kinds): Make them singular.
7794 Adjust all uses.
7795 (&init_tables): When --debug, report the list of rules to ease
7796 tracking changes in autoscan.list.
7797 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7799 2002-09-28 Akim Demaille <akim@epita.fr>
7801 * lib/autoscan/functions, lib/autoscan/headers,
7802 * lib/autoscan/identifiers, lib/autoscan/makevars,

7810 * lib/autoscan/identifiers, lib/autoscan/makevars,
7811 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
7812 `functions' line is now prefixed with `function:'.
7813 * bin/autoscan.in (&init_tables): Adjust.
7815 2002-09-28 Akim Demaille <akim@epita.fr>
7817 From now on, autoscan files must always map a macro name to a
7818 word: there is no `default' macro for autoscan.
7820 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7821 all.
7822 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7823 explicit.
7825 2002-09-28 Akim Demaille <akim@epita.fr>
7827 * bin/autoscan.in (%c_keywords): Remove.
7828 (&used): Keep only track of the words we might be interested in.

7843 Thanks to Bill Moseley and Paul Eggert.
7844 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
7845 the tmpdir must be created.
7846 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
7847 dir be in the build tree, instead of $TMPDIR.
7849 2002-09-27 Akim Demaille <akim@epita.fr>
7851 * bin/autoscan.in: Improve the comments.
7852 (&parse_args): Drop obsolete undocumented options.

7861 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7863 2002-09-26 Akim Demaille <akim@epita.fr>
7865 Single suffix rules and seperated dependencies are not portable.
7867 * doc/autoconf.texi (Installation Directory Variables): Update.
7868 (Limitations of Make): Some about `Single Suffix Rules and
7869 Separated Dependencies'.
7870 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7871 (ifnames, autoscan, autom4te): Un-factor into several rules.
7873 2002-09-25 Paul Eggert <eggert@twinsun.com>
7875 * BUGS (Interoperability bugs): New section. Mention libtool
7876 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
7878 2002-09-24 Paul Eggert <eggert@twinsun.com>
7880 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
7881 make handles suffix-rules differently from GNU make.
7883 * bin/Makefile.am (SUFFIXES, .in): Remove.
7884 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
7885 Move the body of the old .in rule here.
7887 2002-09-16 Akim Demaille <akim@epita.fr>
7889 i960 compilers create `b.out' files by default.
7890 Reported by Ralf Corsepius.
7892 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
7893 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
7895 2002-09-13 Paul Eggert <eggert@twinsun.com>
7897 * doc/autoconf.texi (Particular Headers): Remove obsolete
7898 reference to `struct timezone' in the description of
7899 AC_HEADER_TIME.
7901 2002-09-13 Akim Demaille <akim@epita.fr>
7903 Version 2.54.
7905 * config/config.sub, config/config.guess: Update.
7906 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
7907 * Makefile.am: Adjust.
7909 2002-09-13 Akim Demaille <akim@epita.fr>
7911 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
7912 reading config.log when the compiler is rejected.
7913 Suggested by Guido Draheim.
7915 2002-09-13 Akim Demaille <akim@epita.fr>
7917 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
7918 (chdir_init) might hang when stat'ing mounted directories.
7919 Reported by Vance Shipley.
7921 2002-09-12 Akim Demaille <akim@epita.fr>
7923 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7924 the lists.
7926 2002-09-12 Akim Demaille <akim@epita.fr>
7928 * doc/autoconf.texi (Defining Symbols): Present two different
7929 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
7930 difference between 1 argument calls, and 2-3 argument calls.
7932 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
7934 * doc/autoconf.texi: Review grammar and punctuation.
7936 2002-09-11 Paul Eggert <eggert@twinsun.com>
7938 * doc/autoconf.texi: Fix minor formatting, spelling, and
7939 grammatical typos.
7940 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7941 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7942 is obsolescent.
7944 2002-09-11 Akim Demaille <akim@epita.fr>
7946 * doc/autoconf.texi (Questions): Rename as...
7947 (FAQ): this.
7948 (Defining Directories): New.
7950 2002-09-09 Akim Demaille <akim@epita.fr>
7952 * doc/autoconf.texi (Making testsuite Scripts): Update.
7953 Suggested by Nishio Futoshi.
7955 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
7957 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
7958 plain `@' is wanted.
7960 2002-09-09 Akim Demaille <akim@epita.fr>
7962 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7963 `duplicates', since the algorithm was too naive and could keep
7964 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7965 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7966 Reported by Ralf Corsepius.
7967 * tests/torture.at (Configuring subdirectories): Exercise these
7968 cases.
7970 2002-09-09 Akim Demaille <akim@epita.fr>
7972 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
7973 looking for a replacement file.
7974 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7975 directory is relative.
7976 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7977 directory definition.
7978 Reported by Andreas Schwab and Jim Meyering.
7980 2002-09-06 Akim Demaille <akim@epita.fr>
7982 * doc/autoconf.texi (Setting Output Variables): Clarify what
7983 precious variables are.
7984 Suggested by Pontus Skoeld.
7986 2002-09-05 Akim Demaille <akim@epita.fr>
7988 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7989 (ifnames, autoscan, autom4te): Since we don't only depend on
7990 configure.ac variables (such as VERSION etc.), but also on prefix
7991 and so forth, depend on Makefile, not configure.ac.
7992 Reported by Alexandre Duret-Lutz.
7993 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7995 2002-09-05 Kevin Ryde <user42@zip.com.au>
7997 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7998 doesn't seem to be confined to ia64, just say "some versions".
8000 2002-09-04 Akim Demaille <akim@epita.fr>
8002 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8003 Automake 1.6c.
8004 * Makefile.am (maintainer-clean-local): Remove.
8005 (MAINTAINERCLEANFILES): Remove COPYING.
8007 2002-09-03 Paul Eggert <eggert@twinsun.com>
8009 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8010 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8011 Brinkmann.
8013 2002-09-03 Akim Demaille <akim@epita.fr>
8015 * configure.ac: Bump to 2.53d.
8016 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8017 as of today, on Automake's team suggestion.
8019 2002-09-03 Akim Demaille <akim@epita.fr>
8021 Version 2.53c.
8023 2002-09-02 Akim Demaille <akim@epita.fr>
8025 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8026 SITE_MACRO_DIR.
8027 * configure.ac: Disable SITE_MACRO_DIR.
8029 2002-09-02 Jim Meyering <meyering@lucent.com>
8031 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8032 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8033 Also, tweak grammar: s/make sure to/be sure to/.
8035 2002-09-02 Paul Eggert <eggert@twinsun.com>
8037 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8038 directory names are generally preferable to physical names.
8040 2002-09-02 Akim Demaille <akim@epita.fr>
8042 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8043 Reported by Raja R. Harinath.
8044 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8045 * bin/autoupdate.in: Use error instead of die.
8047 2002-09-01 Paul Eggert <eggert@twinsun.com>
8049 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8050 ordinary shell concatenation rather than echo+tr+sed command that
8051 runs afoul of a long-line-related sed bug in Solaris 8.
8053 * bin/autoheader.in (parse_args): --warning -> --warnings.
8055 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8056 stdout, as traditional "ls" does.
8057 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8058 _AC_COMPILER_EXEEXT_O): Likewise.
8059 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8061 * bin/autoconf.as: Add --prepend-include option. This patch was
8062 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8063 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8065 * bin/autoconf.in, configure: Regenerate.
8067 * doc/autoconf.texi (Special Shell Variables): Mention
8068 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8070 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8071 MAILPATH and set PS1, PS2, PS4 to default values, to work
8072 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8073 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8074 the Autoconf documentation specifies; fall back to "unset" only if
8075 this fails. Use a shell for-loop for this rather than an m4 loop,
8076 to shorten the output script.
8078 2002-08-30 Paul Eggert <eggert@twinsun.com>
8080 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8081 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8082 for the CDPATH problem. Document PWD.
8083 (Limitations of Builtins): Document the problem that "cd $foo" and
8084 "ls $foo" may refer to different directories in shells conforming
8085 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8086 example, since the old example is now out of date.
8088 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8089 FOO" and "ls FOO" talk about different directories; this catches
8090 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8091 spaghetti.
8093 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8094 of rolling our own unset.
8095 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8096 in practice we needn't worry about CDPATH if unset doesn't work.
8098 * Makefile.in, aclocal.m4, bin/Makefile.in,
8099 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8100 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8101 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8102 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8103 tests/Makefile.in: Regenerate with Automake 1.6.3.
8105 * config/config.guess, config/config.sub, config/mkinstalldirs:
8106 Update.
8108 * configure: Regenerate with self.
8110 2002-08-30 Kevin Ryde <user42@zip.com.au>
8112 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8113 default output.
8115 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8117 * bin/autom4te.in (Request::load): Correctly test for "do" read
8118 failure.
8120 2002-08-29 Akim Demaille <akim@epita.fr>
8122 * lib/Autom4te/General.pm (&xqx): New.
8123 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8124 hand, which is not portable.
8125 (&error): New.
8126 * bin/autom4te.in: Use them.
8127 Use &error instead of die.
8128 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8129 Adjust.
8131 2002-08-17 Paul Eggert <eggert@twinsun.com>
8133 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8134 default list of compilers to try, since it was long ago superseded
8135 by the ksh fc builtin. Suggested by Steven G. Johnson.
8137 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8139 * doc/autoconf.texi (Invoking autom4te): End the option table,
8140 fixing a bug introduced by the previous patch.
8141 (Limitations of Make): Add a 'target lookup' subentry in the
8142 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8144 2002-07-29 Mark D. Roth <roth@feep.net>
8146 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8147 options and use $AUTOM4TE_PATH.
8148 * doc/autoconf.texi: Remove documentation of autom4te
8149 --include-envvar and --site-macro-subdir options and document
8150 use of $AUTOM4TE_PATH.
8151 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8152 arguments from each language section.
8154 2002-07-29 Paul Eggert <eggert@twinsun.com>
8156 * doc/install.texi: Include copyright symbol in copyright notice.
8158 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8159 Replace with:
8160 (AM_MAKEINFOFLAGS): New macro.
8161 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8162 * Makefile.am (INSTALL): Use the new macros.
8163 Use -o rather than --output, since "missing" does not grok --output.
8165 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8167 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8168 comments do not always work. Never trust the exit status of
8169 `make -k'.
8171 2002-07-24 Kevin Ryde <user42@zip.com.au>
8173 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8174 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8176 2002-07-23 Paul Eggert <eggert@twinsun.com>
8178 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8179 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8180 apparently treats PATH="nonexistent" as if it contained ".".
8181 Bug reported by Stefan `Sec' Zehl.
8183 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8185 * doc/autoconf.texi (Limitations of Make): Mention the special
8186 handling of the obj/ directory by BSD make.
8188 2002-07-20 Kevin Ryde <user42@zip.com.au>
8190 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
8191 backslashes.
8193 2002-07-19 Akim Demaille <akim@epita.fr>

8202 2002-07-18 Akim Demaille <akim@epita.fr>
8204 Version 2.53b.
8206 2002-07-18 Akim Demaille <akim@epita.fr>
8208 * config/config.guess, config/config.sub: Update.
8210 2002-07-18 Akim Demaille <akim@epita.fr>
8212 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
8213 Automake's parts.
8215 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
8216 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
8217 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
8219 2002-07-18 Akim Demaille <akim@epita.fr>,
8220 Alexandre Duret-Lutz <duret_g@epita.fr>
8222 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install

8228 description of the tarname default.

8232 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
8233 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
8234 latter was not run.
8236 2002-07-17 Akim Demaille <akim@epita.fr>
8238 * lib/Autom4te/General.pm (find_file): Browse the directories in
8239 the order they are given.
8241 2002-07-17 Akim Demaille <akim@epita.fr>
8243 * tests/wrapsh.as, tests/wrappl.as: Merge into...
8244 * tests/wrapper.as: this.
8245 * tests/Makefile.am, configure.ac: Adjust.
8247 2002-07-17 Mark D. Roth <roth@feep.net>

8262 * tests/wrapsh.in: Use --prepend-include instead of --include.
8264 2002-07-17 Akim Demaille <akim@epita.fr>
8266 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): `_' is allowed in
8267 tarnames.

8270 2002-07-17 Akim Demaille <akim@epita.fr>
8272 * lib/autoconf/functions.m4 (AC_FUNC_REALLOC, _AC_FUNC_REALLOC)
8273 (_AC_FUNC_MALLOC): New.

8300 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
8302 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
8303 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
8304 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
8305 so that Emacs setups GNU style for perl-mode and cperl-mode.
8307 2002-06-27 Paul Eggert <eggert@twinsun.com>
8309 * config/install-sh: Quote $src. Prefer || to test's -o option,
8310 as per "Limitations of Builtins".
8311 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
8312 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
8314 * tests/mktests.sh: Use grep instead of fgrep, as per
8315 "Limitations of Builtins".
8317 2002-06-15 Paul Eggert <eggert@twinsun.com>
8319 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
8320 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
8321 so that we consistently test the just-built programs.

8342 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>

8354 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
8356 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use

8363 (AC_REPLACE_FNMATCH): this.
8364 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
8365 AC_FUNC_FNMATCH_GNU.
8367 2002-06-07 Akim Demaille <akim@epita.fr>
8369 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
8370 Rosetta Stone for Unix.
8372 2002-06-07 Akim Demaille <akim@epita.fr>
8374 * bin/autom4te.in (warn_forbidden): When rejecting a token,
8375 suggest m4_pattern_allow.
8376 Suggested by Adam J. Richter.
8378 2002-06-07 Akim Demaille <akim@epita.fr>
8380 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize

8383 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
8384 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
8385 Use ac_config_libobj_dir to find the replacement files.
8386 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...

8441 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
8442 from the default list of compilers to try. Suggested by
8443 Kate Hedstrom.
8444 * NEWS: Document the above.
8445 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
8447 2002-05-17 Paul Eggert <eggert@twinsun.com>
8449 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
8450 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
8451 This improves on an earlier suggestion by H. Peter Anvin.
8453 2002-05-16 Paul Eggert <eggert@twinsun.com>
8455 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
8456 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
8457 Both macros now accept an optional source-dir arg.
8458 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
8460 * NEWS: Document this.
8461 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
8463 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
8464 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
8465 not for GNU extensions; this undoes part of the 2000-11-03 change,
8466 reverting to 2.13-compatible behavior.
8467 Add new optional argument DIR.
8468 (AC_FUNC_FNMATCH_GNU): New macro.
8470 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
8472 2002-05-08 Paul Eggert <eggert@twinsun.com>
8474 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
8475 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
8476 and it causes a 'test' syntax error if it fails.
8477 Bug reported by Stephen Gildea.
8479 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8480 If prototypes are supported, use them to check this at compile-time,
8481 instead of trying to check it at run-time. If we must do a run-time
8482 check, assume that setvbuf is standard when cross-compiling, as
8483 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8484 Bug reported by Paul D. Smith.
8486 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8487 argument specifying location of getloadavg.c. This removes a
8488 FIXME. This idea was taken from Jim Meyering's implementation in
8489 textutils.
8490 * doc/autoconf.texi (Particular Functions): Document this.
8491 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8492 that's what the code does; this fixes a bug reported by
8493 Paul D. Smith.
8495 2002-05-03 Akim Demaille <akim@epita.fr>
8497 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8498 autopoint instead of gettextize.
8499 ($uses_alocal): Rename as...
8500 ($uses_aclocal): this.
8501 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8502 Suggested by Bruno Haible.
8504 2002-05-03 Akim Demaille <akim@epita.fr>
8506 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
8508 2002-04-29 Paul Eggert <eggert@twinsun.com>
8510 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
8511 files to be 1 second older; just set them to be the same time.
8512 Also, sleep 1 second after the first aclocal, to work around
8513 problems with sub-second time stamps on the input files.
8515 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
8517 * doc/autoconf.texi: Mention "set -e -x" lossage
8518 under node "Limitations of Builtins".
8520 2002-04-29 Akim Demaille <akim@epita.fr>
8522 * doc/install.texi: Better wording for setting variables when
8523 running configure.
8524 From Christian Cornelssen.
8526 2002-04-29 Akim Demaille <akim@epita.fr>
8528 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
8529 of lack of $LINENO support, then the test will compare the $LINENO
8530 in testsuite vs. the lineno in the test file. This is wrong, of
8531 course.
8532 Be sure to protect it.
8533 Reported by Patrick Welche.
8535 2002-04-25 Akim Demaille <akim@epita.fr>
8537 * doc/autoconf.texi (Obsolete Macros): Typo.
8538 Reported by Vladimir Volovich.
8540 2002-04-25 Akim Demaille <akim@epita.fr>
8542 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
8543 than some of the input files, hence, on the second run of aclocal,
8544 if some of its input are younger, make them older.
8545 Suggested by Paul Eggert.
8547 2002-04-25 Akim Demaille <akim@epita.fr>
8549 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
8550 Thanks to Paul Eggert.
8552 2002-04-25 Akim Demaille <akim@epita.fr>
8554 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
8555 and ac_subst_vars be sh variables containing the list of
8556 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
8557 DEFAULT diversion.
8558 (_AC_INIT_PREPARE): Use them to log them.
8559 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
8560 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
8561 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
8562 _AC_SUBST_FILES and _AC_SUBST_VARS.
8563 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
8565 2002-04-24 Akim Demaille <akim@epita.fr>
8567 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
8568 autoheader, so that automake does not complain about a missing
8569 config.h.in that was to be created.
8571 2002-04-23 Akim Demaille <akim@epita.fr>
8573 * bin/autoheader.in (parse_args): --warning takes an argument.
8574 Fixes PR/220.

8623 Minor spelling and grammar fixes.
8625 * doc/autoconf.texi: Follow the outline suggested in the GNU
8626 Sample Texts sections of the Texinfo 4.2 manual. Most
8627 importantly, this makes sure that the copyright notices appear in
8628 all output formats. You probably need Texinfo 4.2 to generate
8629 the manual now.

8655 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
8657 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

8685 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

8734 Don't use the KILL diversion, as it kills spurious output, which
8735 results in failures being hidden.

8738 after the second argument.

8808 * doc/autoconf.texi (Limitations of Make): Mention more issue
8809 about VPATH, overriding of macros in sub-makes, and handling of
8810 SHELL.
8812 2002-03-21 Paul Eggert <eggert@twinsun.com>
8814 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8815 problem with here-document buffer boundaries.
8817 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8818 when reinvoking the shell, to work around problems with installers
8819 who put strange things like "cd" commands in their environments.
8821 2002-03-19 Akim Demaille <akim@epita.fr>
8823 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
8824 From Aaron Ucko.
8826 2002-03-19 Akim Demaille <akim@epita.fr>
8828 * bin/autoscan.in (scan_file): Specify the location in `&used'
8829 invocations.
8830 From Nicolas Joly.
8832 2002-03-19 Akim Demaille <akim@epita.fr>
8834 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
8835 From Nishio Futoshi.
8837 2002-03-19 Akim Demaille <akim@epita.fr>
8839 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
8841 2002-03-18 Paul Eggert <eggert@twinsun.com>
8843 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8844 (Limitations of Usual Tools): Add mkdir section.
8846 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8847 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8848 back on AS_DIRNAME to compute prefixes otherwise; this is
8849 roughly what mkinstalldirs does. That way, we need not have
8850 our own filename disassembler. The old disassembler did not
8851 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8853 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8854 Create at_test_all by a series of assignments,
8855 not by a single assignment of a long string. The latter causes ksh
8856 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8857 presumably because of a buffer overrun.
8859 2002-03-14 Paul Eggert <eggert@twinsun.com>
8861 * lib/autotest/general.m4 (at_times_skip):
8862 Renamed from at_times. Now a boolean.
8863 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8864 says 'times: not found'.
8866 2002-03-14 Akim Demaille <akim@epita.fr>
8868 * bin/autoreconf.in (&study_gettextize): New.
8869 (&autoreconf): Handle newest gettextize.
8870 Rerun aclocal if needed.
8871 Suggested by Andreas Schwab.
8873 2002-03-13 Akim Demaille <akim@epita.fr>
8875 * doc/autoconf.texi (Special Shell Variables): More about IFS.
8877 2002-03-13 Akim Demaille <akim@epita.fr>
8879 * doc/autoconf.texi (Header Portability): New.
8880 Add information about stdint.h and inttypes.h from Paul Eggert.
8882 2002-03-13 Akim Demaille <akim@epita.fr>
8884 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
8885 -p'.
8886 From Bob Proulx.
8888 2002-03-12 Akim Demaille <akim@epita.fr>
8890 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
8891 m4_require.
8893 2002-03-11 Andreas Schwab <schwab@suse.de>
8895 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
8896 does not do it if --with-lispdir is given.
8898 2002-03-08 Akim Demaille <akim@epita.fr>
8900 Version 2.53.
8902 2002-03-08 Akim Demaille <akim@epita.fr>
8904 * doc/autoconf.texi (Subdirectories): Clarify that the
8905 subdirectory should exist.
8907 2002-03-08 Akim Demaille <akim@epita.fr>
8909 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
8911 2002-03-08 Akim Demaille <akim@epita.fr>
8913 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8914 aliases the actual variables, and modifications of the former
8915 affect the latter.
8917 2002-03-08 Akim Demaille <akim@epita.fr>
8919 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8920 because of C-c: have m4 output in tmp files, then mv them.
8922 2002-03-08 Akim Demaille <akim@epita.fr>
8924 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
8925 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
8926 * bin/ifnames.in: Copyright update.
8928 2002-03-08 Akim Demaille <akim@epita.fr>

8932 2002-03-05 Akim Demaille <akim@epita.fr>
8934 * doc/autoconf.texi (Specifying Names): Clarification suggested by
8935 Kevin Ryde.
8937 2002-03-05 Akim Demaille <akim@epita.fr>
8939 Version 2.52i.
8941 2002-03-04 Akim Demaille <akim@epita.fr>
8943 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
8944 * lib/autoconf/general.m4 (AC_INIT): More informative error
8945 message for LIBOBJ.
8947 2002-03-04 Akim Demaille <akim@epita.fr>
8949 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
8950 parallel builds.
8952 2002-03-04 Akim Demaille <akim@epita.fr>
8954 * doc/autoconf.texi (Transforming Names): Equality between target
8955 and host is irrelevant.
8956 (Specifying Names, Canonicalizing): Remove all references to the
8957 backward compatibility hooks. Rather, collect them all into...
8958 (Hosts and Cross-Compilation): this new section.
8959 * doc/install.texi (System Type): Ditto.
8960 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8961 that `--host' implies cross-compilation.
8963 2002-03-04 Akim Demaille <akim@epita.fr>
8965 * doc/autoconf.texi (Evaluation Macros): New.
8966 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8967 useless.
8968 (_m4_foreach): Define the variant with immediate evaluation so
8969 that it contains exactly the items, not an expression which
8970 evaluation is the current item.
8971 (m4_re_string, m4_re_word): Don't over quote them.
8973 2002-03-04 Akim Demaille <akim@epita.fr>
8975 Instead of having stacking `shift's evaluated at the end, let
8976 `foreach' loops immediately evaluate them.
8978 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8979 $*. This is the n-th time I change my mind, but hopefully this is
8980 the last...
8981 (m4_lquote): New.
8982 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8983 efficient.
8984 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8985 it was only a hack for m4_text_wrap.
8986 (m4_car2): Remove, replaced by...
8987 (m4_cdr): New.
8988 (_m4_foreach): Adjust.
8989 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8990 m4_bpatsubst for clarification.
8992 2002-03-04 Akim Demaille <akim@epita.fr>
8994 * doc/autoconf.texi (Changequote is Evil): New.
8996 2002-03-03 Kevin Ryde <user42@zip.com.au>

8999 on old systems like SunOS.
9001 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
9003 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,

9018 2002-02-25 Akim Demaille <akim@epita.fr>
9020 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
9021 From Akinori Musha.
9023 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
9025 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
9026 translate \r\n to \n.
9028 2002-02-07 Akim Demaille <akim@epita.fr>
9030 Version 2.52h.
9032 2002-02-07 Akim Demaille <akim@epita.fr>
9034 Fix Autoconf PR/209.
9035 Also reported by Frank Denis.
9037 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
9039 2002-02-07 Akim Demaille <akim@epita.fr>
9041 Fix Autoconf PR/207:
9042 AC_PREFIX_PROGRAM fails with dashed program names
9044 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9045 variable when looking for the prefix program.
9046 Now it also works for shell variables.
9048 2002-02-07 Akim Demaille <akim@epita.fr>
9050 * doc/autoconf.texi (Limitations of Builtins): More about
9051 case/esac.
9053 2002-02-06 Akim Demaille <akim@epita.fr>
9055 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
9056 case/esac, some shells don't support it.
9057 Reported by Zack Weinberg.
9058 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
9060 2002-02-06 Akim Demaille <akim@epita.fr>
9062 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9063 sure not to introduce newlines in at_groups.
9064 * lib/autotest/Makefile.am (autotest.m4f): Typo.
9066 2002-02-06 Akim Demaille <akim@epita.fr>
9068 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9069 is not available.
9071 2002-02-05 Paul Eggert <eggert@twinsun.com>
9073 * doc/autoconf.texi (Specific Compiler Characteristics):
9074 Describe HP-UX cc bug workaround more accurately.
9075 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
9076 not unsigned long.
9077 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9078 cross-compilers, too. This undoes some of the most recent change
9079 to this file.
9081 2002-02-05 Akim Demaille <akim@epita.fr>
9083 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9084 to make sure they are up to date when `check' is run.
9086 2002-02-05 Akim Demaille <akim@epita.fr>
9088 * doc/autoconf.texi (Making testsuite Scripts): Document
9089 package.m4.
9091 2002-02-05 Akim Demaille <akim@epita.fr>
9093 * lib/freeze.mk: New.
9095 2002-02-05 Akim Demaille <akim@epita.fr>
9097 Implement `autom4te --freeze'.
9099 * bin/autom4te.in (&freeze): New.
9100 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9101 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9103 2002-02-05 Akim Demaille <akim@epita.fr>
9105 * bin/autom4te.in (&parse_args): Implement `frozen files are
9106 optional are the sum of the previous files on the command line'.
9107 Also, pass `--reload-state=' on them, so...
9108 (handle_m4): don't.
9109 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9110 (M4sh): Rely on M4sugar.
9111 (Autotest, M4sh, M4sugar): Use frozen files.
9113 2002-01-31 Akim Demaille <akim@epita.fr>
9115 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
9116 * doc/autoconf.texi (Initializing configure): Adjust.
9118 2002-01-30 Akim Demaille <akim@epita.fr>
9120 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9121 alphanumeric to `-' instead of `_'.
9123 2002-01-30 Akim Demaille <akim@epita.fr>
9125 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9126 for plain code, the other for cross-compilation code. The latter
9127 is now run with GCC only.
9128 * doc/autoconf.texi (Compilers and Preprocessors): New.
9130 2002-01-30 Akim Demaille <akim@epita.fr>
9132 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
9133 values.
9134 * doc/autoconf.texi (Initializing configure): Explain how to
9135 change AC_INIT default values.
9137 2002-01-29 Akim Demaille <akim@epita.fr>
9139 * tests/torture.at (Configuring subdirectories): Use configure.in,
9140 so that aclocal 1.4 works.
9141 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9143 2002-01-28 Akim Demaille <akim@epita.fr>
9145 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9146 needs an argument.
9148 2002-01-28 Akim Demaille <akim@epita.fr>
9150 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9151 AUTOTEST_PATH *after* it was set.
9152 Don't put `.' in the PATH: the user should be precise and `./' if
9153 needed. In addition, given that the test suite does some `cd', if
9154 `.' is in the path, the `tested programs' sections will report
9155 programs found in the test suite's directory, while during the
9156 tests (performed in their own directory), these programs are no
9157 longer visible. In other words, the results is confusing and
9158 useless.
9159 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9161 2002-01-24 Akim Demaille <akim@epita.fr>
9163 Version 2.52g.

9172 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
9173 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
9174 Bourne. Use /bin/sh.
9175 From Andreas Buening.
9177 2002-01-24 Akim Demaille <akim@epita.fr>
9179 * config/config.guess, config/config.sub, config/texinfo.tex:

9189 Automake.

9193 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)

9197 2002-01-21 Akim Demaille <akim@epita.fr>

9201 2002-01-21 Akim Demaille <akim@epita.fr>
9203 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
9204 message on invalid options.
9205 * bin/autom4te.in (parse_args): Don't use
9206 Autoconf::General::getopt with non valid options.
9208 2002-01-17 Jim Meyering <meyering@lucent.com>
9210 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
9211 $ac_cv_exeext so we don't use an old, invalid, cached value.
9213 2002-01-11 Akim Demaille <akim@epita.fr>
9215 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
9216 Meyering.

9224 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
9225 package.m4, since is really depends upon configure.ac, not
9226 configure.
9227 * doc/autoconf.texi (testsuite Scripts): Adjust.
9228 * tests/Makefile.am (package.m4): New.
9229 EXTRA_DIST it since its a source.
9231 2002-01-06 Akim Demaille <akim@epita.fr>
9233 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9234 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9235 and PACKAGE_BUGREPORT from here...
9236 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9237 arguments.
9238 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
9239 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
9240 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
9241 * tests/tools.at (autoheader): Adjust.
9242 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
9244 2002-01-06 Akim Demaille <akim@epita.fr>
9246 * bin/autoscan.in (scan_file): Use `&used'.
9248 2002-01-03 Akim Demaille <akim@epita.fr>
9250 * doc/autoconf.texi (Output): Improved wording regarding use of
9251 AC_OUTPUT.

9256 * doc/autoconf.texi (Function Portability): Add notes on sscanf
9257 sometimes needing writable input.
9259 2001-12-17 Jim Meyering <meyering@lucent.com>
9261 * doc/autoconf.texi (New Macros): Tweak wording.
9263 2001-12-14 Akim Demaille <akim@epita.fr>
9265 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9266 trailing files, don't apply `-rf' to files which might not be
9267 created by configure (core, core.*, and *.core), but just `rm -f'.
9268 Suggested by Jonathan Kamens.
9270 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9272 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
9274 2001-12-14 Akim Demaille <akim@epita.fr>
9276 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
9278 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
9280 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
9281 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
9282 abs_srcdir, top_srcpath to abs_top_srcdir.

9296 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
9297 forbidden file descriptors table.
9299 2001-11-26 Akim Demaille <akim@epita.fr>

9302 Map to 1 in order to simplify its uses.
9304 2001-11-26 Akim Demaille <akim@epita.fr>
9306 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
9307 Remove $filepath, useless.
9308 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
9309 variables, they are really part of the tokens.
9310 Split the input line on spaces and then look for tokens.
9311 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9312 because of `lex$U.$(OBJEXT)'.
9313 (&scan_files): Use "@list" instead of join.
9314 * doc/Makefile.am (CLEANFILES): Add *.fns.
9316 2001-11-26 Akim Demaille <akim@epita.fr>
9318 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
9319 Remove, replaced by...
9320 * tests/wrappl.in: Be common for all the Perl executables.
9321 In particular autoscan and autoheader want -I.
9322 * configure.ac: Adjust.
9323 * lib/autoscan/headers: errno.h is portable.
9325 2001-11-26 Akim Demaille <akim@epita.fr>
9327 * bin/autoscan.in (used): New.
9328 Use it.
9330 2001-11-26 Akim Demaille <akim@epita.fr>
9332 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
9333 directives.
9334 (&scan_sh_file): Remove a duplicate pattern.
9335 (&check_configure_ac): Use long options.
9336 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
9338 2001-11-26 Akim Demaille <akim@epita.fr>
9340 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
9341 Before, having a line containing the opening of a multi line
9342 comment made the whole line be ignored.
9344 2001-11-26 Akim Demaille <akim@epita.fr>
9346 * doc/autoconf.texi (Using an Autotest Test Suite): New.
9347 (testsuite Scripts): Be one of its subsection.
9348 (Autotest Logs): New.
9350 2001-11-26 Akim Demaille <akim@epita.fr>
9352 Test groups are now run two directories deeper.
9354 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
9355 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
9356 at_top_builddir.
9357 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
9358 top_srcdir, builddir and top_builddir.
9359 Use `at_*dir' relatively to the directory containing the
9360 suite, use `*dir' when relatively to the current group dir.
9362 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
9364 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
9365 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
9366 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
9367 spelling errors.
9369 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9371 * doc/autoconf.texi (Using System Type): Add an example of `case
9372 $host' usage so people quit using `case $target' everywhere.
9374 2001-11-22 Akim Demaille <akim@epita.fr>
9376 * doc/autoconf.texi (Installation Directory Variables): Englishoes
9377 spotted by Jim Meyering.
9379 2001-11-16 Paul Eggert <eggert@twinsun.com>
9381 This patch implements a `long double' suggestion by Oliver Kiddle.
9383 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9384 static, to catch errors if the value isn't known at compile-time
9385 and the compiler supports dynamic arrays. Change its name from
9386 `_array_' to `test_array' to avoid potential name clashes.
9387 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9388 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9389 better than double. Catch a bug in GCC 2.95.2 x86.
9390 * doc/autoconf.texi (C Compiler): Document the above.
9391 * NEWS: Likewise.
9393 2001-11-13 Akim Demaille <akim@epita.fr>
9395 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9396 hand.
9397 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9399 2001-11-13 Akim Demaille <akim@epita.fr>
9401 * lib/autotest/general.m4 (AT_INIT): After having run the test
9402 group, go back to the initial directory, not to at_suite_dir.
9404 2001-11-13 Akim Demaille <akim@epita.fr>
9406 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9407 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9408 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9409 option.
9410 (AT_CHECK_CONFIGURE): Use absolute paths.
9411 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9412 The problem is still the old one: there is no means in M4 (that I
9413 know about) to create a defining macro, because there is no means
9414 to create `$1' etc., therefore, the defining macro ``swallows''
9415 all the arguments meant to the defined macro.
9417 2001-11-13 Akim Demaille <akim@epita.fr>
9419 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9420 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9421 configure.ac.
9422 * tests/aclocal.m4: Remove, as it is no longer used.
9424 2001-11-13 Akim Demaille <akim@epita.fr>
9426 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9427 variable names when referring to a single test group, or to
9428 `suite' when referring to the whole test suite.
9429 `at_last_test' is removed: m4 compute at_format itself.
9430 (at_stdout, at_stder1, at_stderr): New variables.
9431 (AT_CHECK): Use them.
9433 2001-11-13 Akim Demaille <akim@epita.fr>
9435 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9436 in PATH.
9437 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9438 Do it as soon as a test fails, don't wait till the end of the test
9439 suite.
9440 Don't remove $as_me.[0-9]*, since these files no longer exist.
9442 2001-11-13 Akim Demaille <akim@epita.fr>
9444 * tests/tools.at: Use absolute paths, since we are no longer run
9445 in place.
9447 2001-11-13 Akim Demaille <akim@epita.fr>
9449 Now that tests are running in their own private dir, there is no
9450 need to list the files to remove at the end of tests groups.
9452 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
9453 (AT_data_files, at_data_files): Remove.
9454 (AT_CLEANUP, AT_DATA): Simplify.
9455 (AT_INIT): Adjust.
9456 Remove the group dir if !debug && !failed.
9457 * tests/atspecific.m4: Adjust.
9459 2001-11-13 Akim Demaille <akim@epita.fr>
9461 Start a new layout for Autotest: `testsuite' creates
9462 `testsuite.dir' in which the at-check-line etc. files are to be
9463 found, and `testsuite.dir/003' where the test group 3 is run.
9465 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
9466 at_check_line_file, at_format, at_test_normalized, at_group_dir
9467 are new variables.
9468 Create the directories.
9469 Use absolute paths for at- files.
9470 (AT_CHECK): Adjust.
9472 2001-11-11 Michael Matz <matz@kde.org>
9474 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
9475 (m4_car2): New.
9476 (m4_car): Properly quote arguments.
9478 2001-11-13 Akim Demaille <akim@epita.fr>
9480 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9481 with stricter rules on LIBOBJS.
9483 2001-11-12 Paul Eggert <eggert@twinsun.com>
9485 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9486 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9487 __PROTOTYPES too.
9489 2001-11-12 Akim Demaille <akim@epita.fr>
9491 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9493 2001-11-12 Akim Demaille <akim@epita.fr>
9495 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9496 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
9497 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9498 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9499 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9500 specify to what the macro should be defined (typically to 1).
9502 2001-11-12 Akim Demaille <akim@epita.fr>
9504 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9505 From Jim Meyering.
9507 2001-11-12 Akim Demaille <akim@epita.fr>
9509 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9510 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
9511 definition used by Automake where LEX is +/- "${missing} lex" and
9512 `missing' itself contains variables.
9514 2001-11-12 Akim Demaille <akim@epita.fr>
9516 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
9517 Now that M4sh pushes BODY, the comments were output at the end of
9518 the test suites.
9520 2001-11-08 Akim Demaille <akim@epita.fr>
9522 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
9523 that we can trace macros from aclocal.m4.
9524 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
9525 obsoleted, and redirect to the former anyway.
9526 Reported by Ralf Corsepius.
9528 2001-11-08 Akim Demaille <akim@epita.fr>
9530 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
9531 processed only if present.
9532 * tests/torture.at (Configuring subdirectories): Use autoreconf
9533 instead of successive calls to autoconf.
9534 Add a nonexistent subdirectory to exercise the patch above.
9535 Reported by Ralf Corsepius.
9537 2001-11-08 Kevin Ryde <user42@zip.com.au>
9539 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
9540 doesn't accept .S files.
9542 2001-11-07 Akim Demaille <akim@epita.fr>
9544 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
9545 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
9546 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
9547 * bin/autom4te.in (warn_forbidden): New.
9548 (handle_output): Use it.
9549 Read m4_pattern_forbid with messages.
9551 2001-11-05 Akim Demaille <akim@epita.fr>
9553 * bin/autom4te.in (--normalize): Remove.
9554 * lib/autom4te.in: Adjust.
9556 2001-11-05 Akim Demaille <akim@epita.fr>
9558 * tests/Makefile.am (testsuite): Rename this target as...
9559 ($(TESTSUITE)): this.
9560 From Nicolas Joly.
9562 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
9564 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
9565 the --prefix option, also remove it's argument.
9567 2001-11-05 Akim Demaille <akim@epita.fr>
9569 * doc/autoconf.texi (testsuite Invocation): Update.
9570 (Writing testsuite.at): Update.
9572 2001-11-03 Akim Demaille <akim@epita.fr>
9574 * doc/autoconf.texi: s/@code/@command/ where appropriate.
9576 2001-11-03 Akim Demaille <akim@epita.fr>
9578 * lib/Autom4te/General.pm: (&catfile, &canonfile)
9579 (&file_name_is_absolute): New, wrappers around routines from
9580 File::Spec.
9581 Use and export them.
9582 (&find_configure_ac): Optionally take a directory where to look at.
9583 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
9584 the arguments.
9585 Default @ARGV to `.', not find_configure_ac.
9586 (&autoreconf): Argument is a directory.
9587 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
9588 * doc/autoconf.texi (autoreconf Invocation): Update.
9590 2001-11-03 Akim Demaille <akim@epita.fr>
9592 * lib/Autom4te/General.pm (@export_vars, @export_subs)
9593 (@export_forward_subs): New.
9594 Add basename, dirname, and fileparse.
9595 (@EXPORT): Adjust.
9596 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
9597 Don't look for aclocal flags if we already know aclocal is not
9598 used.
9599 Move aclocal.m4t only if it exists.
9600 Reported by Ezra Peisach.
9602 2001-11-03 Akim Demaille <akim@epita.fr>
9604 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
9605 passed on command line, defaulting to ./configure.ac if present.
9606 (&maybe_autoreconf, File::Find): Remove, unused.
9607 (&autoreconf): If autoconf is not used, don't try to trace.
9609 2001-11-02 Akim Demaille <akim@epita.fr>
9611 * configure.ac: Bump to 2.52g.
9613 2001-11-02 Akim Demaille <akim@epita.fr>
9615 Version 2.52f.
9617 2001-11-02 Akim Demaille <akim@epita.fr>
9619 * config/config.guess, config/config.sub, doc/standards.texi:
9620 * config/lispdir.m4: Update from masters.
9621 * configure.ac: Bump to 2.52f.
9623 2001-11-02 Akim Demaille <akim@epita.fr>
9625 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
9626 Don't run aclocal when aclocal.m4 is not from aclocal.
9627 From Ezra Peisach.
9628 Don't run libtoolize and gettextize if --install is not given.
9630 2001-11-01 Paul Eggert <eggert@twinsun.com>
9632 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
9633 be invoked before _AS_LINENO_PREPARE.
9634 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9635 than character ranges.
9637 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9638 invoking AS_BASENAME. Set the locale variables to 'C' if
9639 possible, as POSIX requires this to get the traditional
9640 behavior.
9641 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9643 2001-10-31 Paul Eggert <eggert@twinsun.com>
9645 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9646 with {}, as that triggers a bug in Bash 2.05.
9648 (_AS_LINENO_PREPARE): Use Sed rather than
9649 Awk. Fix the sed prepass to work even if there are multiple
9650 instances of $LINENO on the same line. Do not substitute for
9651 other variables like $LINENOT. Do not check file dates; such a
9652 check is unreliable on sufficiently fast machines, and removing
9653 the check makes the code simpler and more reliable. Check for
9654 output and chmod failures.
9656 * doc/autoconf.texi (Special Shell Variables): Document
9657 the above.
9659 2001-10-31 Akim Demaille <akim@epita.fr>
9661 * tests/Makefile.am (atconfig): Remove this target, Automake
9662 handles it now.
9664 2001-10-31 Akim Demaille <akim@epita.fr>
9666 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
9667 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
9668 provided, while it is optional.
9669 * configure.ac: Adjust.
9671 2001-10-26 Paul Eggert <eggert@twinsun.com>
9673 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
9674 lib/Autom4te/Struct.pm:
9675 Require Perl 5.005_03 instead of just 5.005, as some tests fail
9676 with 5.005_02.
9678 * doc/autoconf.texi (Special Shell Variables): Document some
9679 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
9681 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
9682 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
9683 eval $LINENO is not portable in practice.
9685 2001-10-24 Akim Demaille <akim@epita.fr>
9687 * lib/Autom4te/General.pm (backname): New.
9689 2001-10-24 Akim Demaille <akim@epita.fr>
9691 * m4/: Remove, merged into...
9692 * config/: here.
9694 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
9696 * doc/autoconf.texi (Shellology): Mention the problems with bash
9697 2.05's use of ANSI quoting in its `set' builtin.
9699 2001-10-22 Paul Eggert <eggert@twinsun.com>
9701 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
9702 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
9703 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
9704 POSIX decided to standardize on the int flavor of strerror_r.
9705 Always do char* test, as there's no reason not to.
9706 Assign to a char* var, to catch strerror_r that returns int*.
9708 * doc/autoconf.texi (Particular Functions):
9709 Document the above changes. Also, document the fact that
9710 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
9712 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
9714 2001-10-20 Akim Demaille <akim@epita.fr>
9716 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
9717 the executable was missing from the log.
9719 2001-10-20 Akim Demaille <akim@epita.fr>
9721 * lib/Autom4te/General.pm (&update_file): If destination is
9722 unchanged, remove the source.
9723 (&up_to_date_p): Don't be verbose, be debug.
9724 * bin/autoreconf.in: No longer support --m4dir.
9725 (&autoreconf): Display the full path of the configure.ac we are
9726 studying.
9727 Trace it only once.
9728 Be sure to honor --force with gettextize.
9729 Always run aclocal.
9730 * doc/autoconf.texi: Adjust.
9732 2001-10-20 Akim Demaille <akim@epita.fr>
9734 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9735 Remove, dead.
9736 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9737 `intl' is already present, as it refuses unless --force.
9738 (&parse_args): Use -I, --include instead of the old Autoconf
9739 options.
9740 ($localdir, $autoconf_dir): Remove.
9741 (@include): New.
9742 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9744 2001-10-19 Jens Petersen <petersen@redhat.com>
9746 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
9747 * doc/autoconf.texi (Particular Programs): Likewise.
9749 2001-10-19 Akim Demaille <akim@epita.fr>
9751 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
9752 file in @configure_input@.
9753 Don't mention `automatically' in addition to `generated'.
9754 * tests/torture.at (#define header templates): Adjust.
9756 2001-10-19 Akim Demaille <akim@epita.fr>
9758 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
9759 comment, explain how to install automatic mode selection.
9760 From Russ Allbery.
9762 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
9764 * bin/autoreconf.in (autoreconf): Display the path to the
9765 configure.ac being studied.
9767 2001-10-18 Paul Eggert <eggert@twinsun.com>
9769 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
9770 long, to work around a bug in the HP C compiler version HP92453-01
9771 B.11.11.23709.GP.
9773 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
9774 (AS_BASENAME_EXPR): New macro.
9775 (AS_BASENAME_SED): Do not assume GNU sed semantics.
9776 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
9777 and fall back on 'sed' only if the other two fail. This makes
9778 AS_BASENAME act more like AS_DIRNAME.
9779 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
9780 contains white space.
9781 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
9782 Use AS_DIRNAME, since I think it's now DOS-friendly.
9783 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9784 Allow "dirname //FOO" to return either / or //, as POSIX allows
9785 either behavior.
9787 2001-10-10 Akim Demaille <akim@epita.fr>
9789 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
9790 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
9791 From Eric Sharkey.
9793 2001-10-10 Akim Demaille <akim@epita.fr>
9795 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
9796 m4_define, since...
9797 (_AS_ECHO_N): AS_REQUIREs it.
9799 2001-10-10 Akim Demaille <akim@epita.fr>
9801 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)

10016 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

10050 * tests/fortran.at (GNU Fortran 77): there.
10051 * doc/autoconf.texi (autoconf Invocation): Fix the example:
10052 AC_TRY_RUN is about compilation, not shell commands.

10057 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
10058 Raja R Harinath:

10061 enough.

10112 * doc/autoconf.texi (Common Shell Constructs): Rename as...

10214 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

10230 CR issues on DOSish systems).
10232 2001-09-19 Akim Demaille <akim@epita.fr>
10234 * lib/autotest/general.m4: Englishoes.
10235 From Tim Van Holder and Alexey Mahotkin.
10237 2001-09-18 Paul Eggert <eggert@twinsun.com>
10239 * doc/autoconf.texi (Common Shell Constructs): New node,

10255 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10256 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check

10258 getpgrp. This simpler test supports the revised documentation,
10259 and is all that AC_FUNC_GETPGRP's users really need.
10261 2001-09-18 Akim Demaille <akim@epita.fr>
10263 * doc/autoconf.texi (Limitations of Make) <$<>: New.
10265 2001-09-18 Akim Demaille <akim@epita.fr>
10267 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
10268 `{}'.
10269 * lib/autotest/general.m4 (AT_INIT): Adjust.
10271 2001-09-18 Paul Wagland <paul@wagland.net>
10273 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
10274 correctly.
10275 Add test for AS_BASENAME.
10276 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10277 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10278 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10279 * tests/base.at: Fixed the expected responses. The old ones were
10280 one line out...
10281 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10282 the documentation claims it should (and how it behaved in 2.13).
10284 2001-09-18 Akim Demaille <akim@epita.fr>
10286 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
10287 the AC_CONFIG_COMMANDS invocation.
10288 This also solves the name clash problems.
10289 Don't set the package's ID.
10290 * lib/m4sugar/Makefile.am (version.m4): Revamp.
10291 No longer to be shipped.
10292 (version.in): Remove.
10293 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
10294 * lib/autoconf/status.m4: Adjust.
10295 Use `m4_PACKAGE_STRING'.
10296 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
10297 the only optional argument is the name of the test suite.
10298 Expect `package.m4' to define the package signature.
10299 * lib/autom4te.in (Autotest): Add `package.m4?'.
10300 * tests/Makefile.am (package.m4): New.
10301 * tests/suite.at: ifnames is a victim.
10303 2001-09-18 Akim Demaille <akim@epita.fr>
10305 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
10306 AC_LIBSOURCE, AC_CONFIG_FILES.
10307 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
10308 program version string doesn't match the package's.
10309 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
10310 after `(cached)'.
10312 2001-09-17 Paul Eggert <eggert@twinsun.com>
10314 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10315 Allow expression to return any value that can fit into unsigned long
10316 (not int, as before). Check for output errors.
10318 2001-09-17 Bruno Haible <haible@ilog.fr>
10320 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10321 Always include <stdio.h> and <stdlib.h>. Evaluate
10322 the expression in an extra function before these includes. Call
10323 fprintf "%d" only after ensuring the argument is of type 'int'.
10324 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
10326 2001-09-17 Paul Eggert <eggert@twinsun.com>
10328 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10329 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10330 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10331 when they don't exist.
10333 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
10334 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
10335 need it.
10337 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
10338 version with the version used by fileutils 4.1, except use
10339 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
10340 we don't need it.
10342 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
10344 2001-09-13 Akim Demaille <akim@epita.fr>
10346 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
10347 _first_.
10348 Reported by Gerrit P. Haase.
10350 2001-09-13 Akim Demaille <akim@epita.fr>
10352 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

10369 Likewise.
10370 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
10371 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
10372 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
10373 AT_tests_all for consistency.
10374 Set at_victims.
10375 (AT_VICTIMS): Similar to AT_KEYWORDS.
10376 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
10378 2001-09-13 Akim Demaille <akim@epita.fr>
10380 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
10382 2001-09-13 Akim Demaille <akim@epita.fr>
10384 * lib/autotest/general.m4 (AT_INIT): Create and remove
10385 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
10386 test suites can cohabit.
10388 2001-09-13 Akim Demaille <akim@epita.fr>
10390 * tests/mktests.sh: Don't output banners for empty test files.
10392 2001-09-13 Akim Demaille <akim@epita.fr>
10394 Test suites can be run independently of configure.

10429 (AT_CLEANUP_FILE_IFELSE, AT_CLEANUP_FILE): Rename as...

10432 (AT_SETUP): Reset AT_line, AT_keywords, AT_description.
10433 No longer fill the HELP diversion.

10436 (m4_list_append): Remove.
10438 Spread a few keywords in the Autoconf test suite.
10440 2001-09-10 Akim Demaille <akim@epita.fr>
10442 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

10444 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): New.
10445 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

10458 2001-09-07 Akim Demaille <akim@epita.fr>
10460 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
10461 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
10462 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
10463 related variables into `at_package_*'.

10473 Move toward possibly stand-alone test suites.
10475 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
10476 in addition, it introduces useless differences in logs.
10477 (AT_INIT): Let atconfig and atlocal be both optional.
10478 Adjust PATH computation.
10479 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.
10481 2001-09-07 Akim Demaille <akim@epita.fr>

10494 * bin/autom4te.in: --language is -l, not -s.
10496 2001-09-05 Akim Demaille <akim@epita.fr>
10498 Be ready to handle filenames as stupid as `dnl.at', for if even
10499 the maintainer is dumb enough to do that...
10501 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
10502 excellence in M4 quotation: consider `__file__' is active.
10504 And BTW, when invoking m4, pass the --include in the right order:
10505 the wrong one.
10507 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
10508 4m.
10510 2001-09-05 Akim Demaille <akim@epita.fr>
10512 * lib/Autom4te/XFile.pm: New lib file.
10513 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
10514 * bin/autoheader.in: Use it.
10516 2001-09-05 Akim Demaille <akim@epita.fr>
10518 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff

10530 2001-09-05 Akim Demaille <akim@epita.fr>
10532 CVS GNU M4 doesn't like `undefine(undefined)'.
10534 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
10535 New, extracted from main.
10536 Use IO::File wherever possible.
10537 (input.m4): Be constant, use -I instead of hard coding $tmp.
10538 Therefore be a quoted heredoc.
10539 Don't invoke `_au_disable', since ac was not loaded, but just
10540 `unm4.m4'.
10542 2001-08-31 Akim Demaille <akim@epita.fr>
10544 Version 2.52d.
10546 2001-08-31 Akim Demaille <akim@epita.fr>

10549 previous patch.

10560 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
10561 (Making testsuite Scripts): Update.

10565 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
10567 2001-08-31 Akim Demaille <akim@epita.fr>
10569 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
10570 (testsuite Scripts): There is no such thing as `atconfig.in'.
10571 And actually one diagram is missing: test suite runtime.
10573 2001-08-31 Akim Demaille <akim@epita.fr>
10575 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
10576 inverse order.
10578 2001-08-31 Akim Demaille <akim@epita.fr>
10580 * bin/autoupdate.in (@include): `installcheck' revealed the path
10581 to m4sugar was lacking!
10583 2001-08-31 Akim Demaille <akim@epita.fr>
10585 * man/Makefile.am (.x.1): We really have to pass
10586 autom4te_perllibdir.
10588 2001-08-31 Akim Demaille <akim@epita.fr>
10590 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
10591 debug scripts, in particular passing explicitly listed tests to
10592 run is stupid.
10594 2001-08-31 Akim Demaille <akim@epita.fr>
10596 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
10597 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
10598 Use directly autom4te, not autoconf.
10599 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
10601 2001-08-31 Akim Demaille <akim@epita.fr>
10603 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

10610 2001-08-31 Akim Demaille <akim@epita.fr>
10612 * bin/autom4te.in (&parse_args): Die on unknown languages.
10613 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
10614 need for autoconf.
10615 Promote --include over --macrodir and other obsolete options.
10617 2001-08-31 Akim Demaille <akim@epita.fr>
10619 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

10621 * bin/autom4te.in ($autoconf): Pass --force.
10622 `print $out' doesn't print `$_' but `$out'.
10623 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
10624 (autoheader): Pass --force since the test suite goes too fast for
10625 the time stamps.
10626 Adjust to the new autoheader messages.
10628 2001-08-31 Akim Demaille <akim@epita.fr>
10630 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
10631 Check the completeness of the #template.
10632 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
10633 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
10634 invocation.
10636 2001-08-31 Akim Demaille <akim@epita.fr>
10638 * lib/Autom4te/General.pm (&find_file, &update_file): New.
10639 * bin/autoupdate.in, bin/autoheader.in: Adjust.
10640 Drop AC_MACRODIR dead for real.
10641 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
10642 `autoheader: `config.hin' is created'.
10643 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
10645 2001-08-31 Akim Demaille <akim@epita.fr>
10647 * bin/autoheader.in: Rewrite in Perl.
10648 * tests/autoheader: Adjust.
10650 2001-08-31 Akim Demaille <akim@epita.fr>
10652 * bin/autoconf.in (--include, -I): New option.
10653 Map --localdir, --autoconf-dir onto it.
10654 Forward autom4te's options instead of interpreting them.
10655 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
10656 There is no such envvar since the inception of autom4te.cfg.
10657 * bin/autom4te.in (&parse_args): Uniquify `@include'.
10658 * bin/autoupdate.in: Adjust, and perform more control.
10659 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
10660 * tests/autoconf: Dittowise.
10662 2001-08-31 Akim Demaille <akim@epita.fr>
10664 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
10665 * bin/autom4te.in (&find_file): Support `FILE?' standing for
10666 optionally `FILE'.
10667 Use -e, not -f, since /dev/null for instance is OK.
10668 (&parse_args): Adjust.
10669 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
10671 2001-08-31 Akim Demaille <akim@epita.fr>
10673 * configure.ac: Also find tested executables in bin.
10674 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
10675 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
10676 installed peer executables, only PATH is allowed to resolve it.
10677 Pass `autoconf_dir' via options, not via invisible envvars.
10678 * lib/Autom4te/General.pm (&find_peer): Remove.
10679 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
10680 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
10681 * man/Makefile.am: Let help2man rely on PATH instead of trying to
10682 find the executables for it.
10683 * tests/Makefile.am: Major cleanup. Too lazy to document...
10684 * tests/atlocal.in: Remove all the obscure envvar manipulations.
10685 We only need PERL.
10686 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
10687 indeed related to running the test suite, while passing
10688 --autoconf-dir and others is related to running non installed
10689 Autoconf executables. So don't do that, leave it to...
10690 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
10691 * tests/autoscan: New.
10692 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
10693 refer to library files: rely on --language.
10695 2001-08-29 Akim Demaille <akim@epita.fr>
10697 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
10698 s/--set/--language/.
10700 2001-08-29 Akim Demaille <akim@epita.fr>
10702 * doc/autoconf.texi: Strip the @nodes.
10703 Suggested by Paul Eggert.

11181 2001-08-15 Akim Demaille <akim@epita.fr>
11183 * bin/autom4te.in (@m4_warning): New.
11184 (&handle_m4): Use it.
11185 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
11186 warnings are issued at each run.
11187 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
11188 is in the src tree.
11190 2001-08-15 Akim Demaille <akim@epita.fr>
11192 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
11193 don't waste time running `autoupdate --version' works.
11194 * tests/tools.at (autoupdating AC_PREREQ): Likewise.

11255 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11257 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
11258 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
11259 * doc/autoconf.texi (C Compiler Characteristics): Update
11260 documentation for AC_C_BIGENDIAN.
11262 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11264 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11265 magic values from an object file when cross-compiling.
11266 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11268 2001-08-10 Akim Demaille <akim@epita.fr>
11270 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11271 effects.
11272 Suggested by Russ Allbery.
11274 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11276 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11277 current $prefix to the sub-configures.
11279 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11281 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
11282 extension (needed on BeOS). Reported by Guido van Rossum.
11284 2001-08-09 Akim Demaille <akim@epita.fr>
11286 * bin/autom4te.in ($icache): Load it only if older than autom4te.
11288 2001-08-07 Akim Demaille <akim@epita.fr>
11290 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11291 removed.
11292 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11293 No need to remove the files before and after the each test, before
11294 each test and at the end of the suite is enough.
11295 Display only the children `times', not the shell's.
11296 If the test failed or was skipped, at-times is not available.
11298 2001-08-07 Akim Demaille <akim@epita.fr>
11300 Always produce testsuite.log, including when there are no
11301 failures. This helps getting information on skipped tests, and
11302 duration of the tests. Err, implement the latter btw.
11304 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
11305 Dump information on the first run of each test.
11306 (AT_CLEANUP): Create `at-times' containing the duration of the
11307 test group.
11309 2001-08-07 Akim Demaille <akim@epita.fr>
11311 The use of `dumpstat' revealed that `len' was used although it
11312 should not. m4_text_wrap was using it, but in the Autoconf world
11313 where it is legal. Hence (i) test M4sh in its own world, not
11314 Autoconf's, and (ii), ahem, fix the bug :)
11316 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11317 does not like `' instead of [].
11318 (AT_INIT): Forbid `^_?AT_'.
11319 And don't output such tokens.
11320 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11321 `script.as', and `autom4te.cache'.
11322 Remove `empty' and `macro' which are no longer used.
11323 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11324 * tests/m4sugar.at: Use it.
11325 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11327 2001-08-07 Akim Demaille <akim@epita.fr>
11329 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
11331 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
11333 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
11335 2001-08-04 Akim Demaille <akim@epita.fr>
11337 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
11338 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
11339 AC_TRY_LINK.
11340 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
11341 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
11342 (AC_F77_MAIN): Likewise.
11344 2001-08-04 Akim Demaille <akim@epita.fr>
11346 Don't rely on M4sugar outputting the patterns in files, since we
11347 might process the output _without_ running m4, hence without these
11348 files.
11350 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
11351 * bin/autom4te.in (@Request::includes): Remove, unused.
11352 (@Request::source): Rename as...
11353 (@Request::input): this.
11354 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
11355 (&handle_output): Fetch the patterns from the traces.
11356 `$forbidden' and `$allowed' are constant: use m//o.
11357 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
11358 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
11360 2001-08-04 Akim Demaille <akim@epita.fr>
11362 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
11363 autoconf', i.e., in addition to caching traces, cache the output.
11365 * bin/autom4te.in (Request::cache): Rename as...
11366 (Request::id): this.
11367 ($cache, $icache, $tcache, $ocache): New.
11368 (&handle_m4): Save M4 output in the cache instead of $tmp.
11369 (&handle_output): Adjust.
11370 (&up_to_date_p): Check that the output cache is up to date too.
11371 (top level): Run `&handle_m4' iff force or the cache is invalid.
11372 Run `&handle_output' if the output cache is more recent.
11374 2001-08-04 Akim Demaille <akim@epita.fr>
11376 * bin/autom4te.in ($force): New.
11377 (&parse_args, &print_usage): -f, --force is a new option.
11378 (&handle_output): CPP directives might have spaces after `#'.
11379 (&parse_args): The first file only can be frozen.
11381 2001-08-04 Akim Demaille <akim@epita.fr>
11383 Don't let autom4te compute the `include' traces several times:
11384 first check that the trace cache file is up to date, and then
11385 compare its timestamp with that of the output.
11387 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
11388 the preamble. Don't require 5.005 as Autom4te::General does it,
11389 and better yet (use `use', not `require'!).
11390 * lib/Autom4te/Struct.pm: Rename the last occurrences of
11391 Class::Struct as Autom4te::Struct.
11392 * lib/Autom4te/General.pm (File::stat): Use it.
11393 (&mtime): New, export it.
11394 * bin/autom4te.in: Use it.
11395 Declare `$req' is invalid if it is outdated.
11396 Don't declare it valid before saving it if something went wrong.
11398 2001-08-04 Akim Demaille <akim@epita.fr>
11400 Autom4te shall not encode Autoconf data, and preselecting traces
11401 must be proposed to the users.
11403 * bin/autom4te.in (@required_trace): Remove.
11404 (@preselect): New.
11405 (&parse_args, &print_usage): -p, --preselect is a new option.
11406 (&up_to_date_p): Adjust.
11407 * bin/autoconf.in: Preselect some Autoconf macros.
11409 2001-08-04 Akim Demaille <akim@epita.fr>
11411 * tests/tools.at (autoconf --trace: user macros): Check traces on
11412 macros invoked without arguments, and macros invoked with multiple
11413 lines arguments.
11415 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
11417 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
11418 arguments.
11420 2001-08-03 Akim Demaille <akim@epita.fr>
11422 * bin/autoconf.in ($@): Work around the usual sh bug.
11423 From Nicolas Joly.
11425 2001-08-03 Akim Demaille <akim@epita.fr>
11427 Clean up the handling of the M4 builtins tracing exception.
11429 * bin/autom4te.in (Request::request): Don't complete M4 builtins
11430 trace requests.
11431 (@m4_builtins): Rename as...
11432 (@m4_builtin): this.
11433 (%m4_builtin_alternate_name): New.
11434 (&parse_args): Complete the trace requests with alternate names.
11435 (&handle_traces): Hence no longer do it here.
11436 (&trace_requests): Remove, unused.
11438 2001-08-03 Akim Demaille <akim@epita.fr>
11440 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
11441 m4_if, and m4_wrap.
11443 2001-08-03 Akim Demaille <akim@epita.fr>
11445 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
11446 (m4_divert_pop): Dump the whole diversion stack when a diversion
11447 mismatch happens.
11448 * bin/autom4te.in (&handle_output): Remember of the first
11449 occurrence of a possibly undefined macro, not the last.
11450 Complain about the possibly undefined macros in the same order as
11451 the appear in the output.
11452 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
11453 * tests/tools.at (autoconf: forbidden tokens, basic)
11454 (autoconf: forbidden tokens, exceptions): No longer sort
11455 autoconf's stderr, as it is now deterministic.
11456 Check that `dnl' is caught.
11458 2001-08-01 Akim Demaille <akim@epita.fr>
11460 * configure.ac: Bump to 2.52c.
11462 2001-08-01 Akim Demaille <akim@epita.fr>
11464 Version 2.52b.

11472 2001-08-01 Akim Demaille <akim@epita.fr>
11474 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
11475 `die'.
11476 (&END): New.
11477 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
11478 `END', as `Autom4te::General::END' will be triggered.
11479 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
11480 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

11915 cross-language link tests can be performed successfully.
11916 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
11917 after $LIBS, for consistency; this should be the general rule since

11993 * doc/autoconf.texi (Redefined M4 Macros): New.
11995 2001-06-23 Akim Demaille <akim@epita.fr>

12036 ./configure --program-suffix=foo produces `transform=s,$$,foo,;',
12037 but some sed choke on multiple `;', and other tools (e.g.,
12038 Automake), include the separator themselves.
12040 * acgeneral.m4 (AC_ARG_VAR): Be sure not to leave extra `;'.
