12 * build-aux/texinfo.tex: automake 1.10
14 * NEWS: Remove AC_CACHE_CHECK_INT.
15 * doc/autoconf.texi (Caching Results): Likewise.
16 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
17 AC_CACHE_CHECK_INT, since it's no longer public.
18 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
19 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
21 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
23 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
25 2006-10-19 Eric Blake <ebb9@byu.net>
27 * lib/m4sugar/m4sugar.m4 (m4_mkstemp): New macro.
28 (m4_maketemp): Avoid warnings with M4 1.9a.
29 * lib/emacs/autoconf-mode.el (autoconf-font-lock-keywords): Color
30 m4_mkstemp.
31 * doc/autoconf.texi (Redefined M4 Macros): Document m4_mkstemp.
32 * NEWS: Likewise.
34 2006-10-16 Eric Blake <ebb9@byu.net>

39 Standards.

47 2006-10-14 Stepan Kasal <kasal@ucw.cz>
49 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
50 looking for special shell characters.
51 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
52 macro defined by AS_VAR_PUSHDEF before passing it as a
53 parameter.
54 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
55 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

61 AS_VAR_* properly.
62 * tests/m4sh.at (AS_LITERAL_IF): New test.
64 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
66 (Imported from Automake.)
67 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
68 which incorrectly sets the mode of an existing destination
69 directory. In some cases the unpatched install-sh could do the
70 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
71 system. We hope this is rare in practice, but it's clearly worth
72 fixing. Problem reported by Alex Unleashed in
73 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
74 Also, don't bother to check for -m bugs unless we're using -m;
75 suggested by Stepan Kasal.
77 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
79 Import this change from Automake:
81 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
82 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
83 is enabled by default with gnu and gnits strictness.
84 Report from Bruno Haible.
86 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
87 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
88 gnu and gnits modes.
90 Import this change from Config:
92 2006-09-20 Ben Elliston <bje@gnu.org>
93 * build-aux/config.sub (score, score-*): New.
95 Import this change from Gnulib:
97 2006-09-16 Karl Berry <karl@gnu.org>
98 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
99 to avoid sectioning errors.
101 Import these changes from Texinfo:
103 2006-10-04 Karl Berry <karl@gnu.org>
104 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

108 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
109 (\code): must use new \...Char values, since now ` is active.
111 2006-08-26 Karl Berry <karl@gnu.org>
112 * build-aux/texinfo.tex (\textdegree): New command.
114 2006-08-12 Karl Berry <karl@gnu.org>
115 * build-aux/texinfo.tex (error \box0): smaller font.
117 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
119 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
121 2006-10-13 Stepan Kasal <kasal@ucw.cz>
123 * doc/autoconf.texi (Autoheader Macros): Warn that the text
124 added to the template can get mangled.
126 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
128 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
129 include the default headers, and redefine obstack_chunk_alloc
130 and obstack_chunk_free. Fixes false failure with glibc.
132 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
134 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
135 for backward compatibility with Libtool 1.5.22. Problem reported
136 by Ralf Wildenhues.
138 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
140 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
141 AC_PROG_CC.
142 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
144 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
146 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
147 the NonStop platform.
148 * doc/autoconf.texi (Posix Variants): Likewise.
149 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
151 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
152 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
153 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
154 Use a better substitute, by inspecting the output of "ls"
155 rather than just using ":".
156 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
157 rather than AS_EXECUTABLE_P, since we needn't worry about
158 non-regular files here.
160 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
161 due to configuration hassles with this. See Tonya Underwood's report
162 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
163 * doc/autoconf.texi (Special Shell Variables): Likewise.
165 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
166 Stepan Kasal <kasal@ucw.cz>
168 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
169 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
171 2006-10-11 Stepan Kasal <kasal@ucw.cz>
173 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
174 initialization which is not inherited through the environment
175 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
176 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
178 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
180 * doc/autoconf.texi (Limitations of Usual Tools): Describe
181 problems with mkdir -p -m.
183 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
185 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
186 comment about ac_cpp_err; it was incorrect, and anyway
187 ac_cpp_err is being removed below.
188 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
189 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
190 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
191 nobody uses it.
192 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
193 with werror_flag and conftest.err and so forth. This is more
194 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
195 and anyway the user shouldn't normally want to see this gorp logged.
196 Problem reported by Ralf Wildenhues.
197 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
198 empty, not 'no', since the rest of the code uses 'test -z'.
200 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
202 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
203 Use a single call to AC_DO_TOKENS rather than multiple, for
204 efficiency.
205 (_AC_LINK_IFELSE): Test that resulting file is executable.
206 Problem reported by mwoehlke in
207 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
209 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
210 than creating a file to use with test -x; this is much faster.
212 2006-10-02 Bruno Haible <bruno@clisp.org>
214 * lib/autom4te.in (Automake-preselections): Add
215 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
217 2006-09-27 Stepan Kasal <kasal@ucw.cz>
219 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
220 standard error, `experr' should be used, not `expout'.
222 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
224 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
225 fseeko testing program twice; just use the earlier result.
226 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
227 Set cache var to 'unknown' (not 'no') if leaving the macro unset
228 still doesn't let the program compile.
229 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
230 failed.
232 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
233 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
234 include it, without including anything else.
235 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
236 expressions.
237 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
239 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
241 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
242 `error.h', and include it, for a `error_at_line' prototype.
243 Use a nonempty format string in the link test.
244 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
245 for a declaration of wait3.
247 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
249 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
250 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
251 can apply to constants too, and that it checks for macro defns.
252 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
253 and simply cast the identifier to void. This handles structure
254 values. Problem reported by Ralf Wildenhues.
255 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
257 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
259 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
260 structure, and function symbols.

264 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
265 member.

274 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
276 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): Avoid `gcc -Wall'
277 warnings (uninitialized value).
278 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
279 present.
280 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add
281 parentheses.
282 (AC_STRUCT_TM): Likewise, avoid unused variables.
284 2006-09-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
286 * lib/autoconf/c.m4 (_AC_ARG_VAR_LDFLAGS): Update comment.
287 (_AC_ARG_VAR_LIBS): New macro: let LIBS be precious.
288 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Call _AC_ARG_VAR_LIBS.
289 * lib/autoconf/fortran.m4 (AC_PROG_F77, AC_PROG_FC): Likewise.

309 * m4/m4.m4 (AC_PROG_GNU_M4): Check for m4 --debugfile support.
310 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
311 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
312 --error-output, to avoid warnings with M4 2.0.
314 2006-09-19 Stepan Kasal <kasal@ucw.cz>
316 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be
317 consistent with _AH_CHECK_FUNCS and _AH_CHECK_HEADERS.
318 * lib/autoconf/headers.m4 (AH_CHECK_HEADERS_DIRENT): Likewise.
320 2006-09-15 Stepan Kasal <kasal@ucw.cz>

323 expansion of AC_CHECK_FUNCS.
325 2006-09-14 Stepan Kasal <kasal@ucw.cz>
327 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
328 mistaken comment: the path has to be relative; do not use
329 the path at runtime.
331 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
333 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

338 * doc/autoconf.texi (Setting Output Variables): Fix example to
339 not show `--silent' being passed to a `configure' re-run.
341 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
343 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
344 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
345 for the existence of the directory at configure-time. That's
346 too late, anyway. Problem reported by Stefan Seefeld.
348 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
349 7.1.4 /usr/bin/posix/sh described by Tim Rice in
350 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
352 2006-09-11 Stepan Kasal <kasal@ucw.cz>
354 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
355 works with GNU M4 1.4.3 again; make the normalized form
356 match the current m4 message; fix the description.
357 * test/tools.at (autom4te cache): Adapt to the change.
359 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
361 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
362 to catch glibc bug 2821
363 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
365 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
366 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
367 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
368 assume C89.
370 2006-09-08 Stepan Kasal <kasal@ucw.cz>
372 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the
373 preselections ...

380 AM_ENABLE_MULTILIB.
382 2006-09-05 Paul Eggert <eggert@cs.ucla.edu>
384 * doc/autoconf.texi (Preset Output Variables): srcdir and
385 top_srcdir are not necessarily relative. Problem reported
386 by Dries Kimpe.
388 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
390 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
391 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
392 accept files with extension `.f'. For consistency, also prefer
393 xlf over f77.
394 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
395 from last patch.
397 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>

410 before AC_PROG_FC, due to a bug in Autoconf.
412 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
414 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
415 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
416 except the first two arguments are reversed.
417 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
418 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
419 caches nor outputs a diagnostic. Suggested by Bruno Haible.
420 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
421 equivalent to the old AC_COMPUTE_INT.
422 (AC_COMPUTE_INT): No longer caches or reports. New signature.
423 All uses changed to AC_CACHE_CHECK_INT.
424 * tests/base.at (AC_CACHE_CHECK_INT): New test.
425 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
427 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
429 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
430 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
431 programs should use their Gnulib counterparts.
432 * doc/autoconf.texi (Particular Functions): Likewise.
433 (Macro Names, testsuite Invocation): Replace uses of these
434 obsolete macros with uses of non-obsolete macros.
436 2006-08-29 Eric Blake <ebb9@byu.net>
438 * configure.ac (AC_INIT): Bump to 2.60b.
439 * NEWS: Update.
441 2006-08-28 Eric Blake <ebb9@byu.net>
443 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Fix logic that was
444 mistakenly swapped on 2006-08-15.
446 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
448 * NEWS: Version 2.60a.
450 2006-08-25 Stepan Kasal <kasal@ucw.cz>
452 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Remove the IPA/IPO
453 file created by the PGI compiler.
455 2006-08-25 Noah Misch <noah@cs.caltech.edu>
457 * lib/Autom4te/General.pm (END): Use `File::Path::rmtree' to
458 simplify the code.
460 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
462 Fix Lex library problem reported to us by Julio Garvia.
463 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
464 for the default, which the user can override.
465 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
466 deal with LEXLIB.
467 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
468 didn't work if some values were cached but not others. Test for
469 broken lex libraries like native ia64-hp-hpux11.22; see
470 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
471 work around the problem by preferring an empty LEXLIB to -lfl or
472 -ll. Let the user set LEXLIB='' to indicate no library needed.
474 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.

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

617 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
618 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
619 this.
621 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
623 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
624 problems with arg script text that doesn't end in newline, and

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

668 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
669 compiler complains about it, even if things works after the
670 complaint. Problem reported by Peter O'Gorman.
672 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
673 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
674 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
676 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
678 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
679 after -R regardless of host. Patrick Welche reports that this
680 fixes things on NetBSD 3.99.
682 * NEWS: Recommend M4 1.4.5.
683 * README: Likewise.
684 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

686 to match M4 1.4.5.
688 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
690 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
691 under AC_C_VOLATILE.
692 (Volatile Objects): Be a little less skeptical about what
693 "volatile" means. Derived from thoughts by Ben Pfaff in
694 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
696 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
698 * doc/autoconf.texi: Fix some typos.
700 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
702 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
703 more globally, since the 2006-06-30 patch didn't suffice. Problem
704 reported by Keith Marshall. Also, don't bother with builddir2,
705 since it shouldn't be needed any more.
707 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
709 * doc/autoconf.texi (Generic compiler characteristics):
710 Document AC_COMPUTE_INT. Fix wrong statements on Default
711 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
713 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
714 (_AC_COMPUTE_INT): Add obsoletion warnings.

718 * NEWS: Document change.
720 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
722 * doc/autoconf.texi (Volatile Objects): New section.
724 * NEWS: Document previous change.
726 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
728 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
729 Require that long long int be at least 64 bits wide. C99 requires
730 this and enough programs depend on it so we should check for it.
731 Bruno Haible reports in
732 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
733 that long long int is 32 bits wide with some nonstandard compilers.
734 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
736 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
738 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
739 to a nonexistent file, so that we don't have to worry about
740 a local site configuration that doesn't use /usr/local.
741 Problem reported by Keith Marshall in
742 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
744 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
746 * doc/autoconf.texi: Be more consistent about using @acronym with
747 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
748 quite right (it talked about "OSF/Tru64", even though the
749 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
750 and it even mentioned "OSF 4"!) and at this point there's little
751 reason to talk about OSF any more, since it died in 1994.
752 (Specific Compiler Characteristics): Simplify example of
753 negative-size array.
754 (File Descriptors): Reorder to make the text flow better.
755 Remove joke about "appreciate the various levels"; I didn't get it.
756 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
757 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
758 (File Descriptors, Limitations of Usual Tools):
759 Tone down the advice against renaming or removing open files.
760 (Limitations of Usual Tools): Add a new section, on 'rm'.
762 2006-06-26 Stepan Kasal <kasal@ucw.cz>
764 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
765 -lXt in LIBS, idea from Karsten Hopp; this was due since
766 this change:
768 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
769 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
770 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
771 (which belong to Xt, not X itself). See Debian bug 327655.
773 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
775 * configure.ac (AC_INIT): Bump to 2.60a.
776 * NEWS: Update.
778 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
780 Version 2.60.
782 * configure.ac, NEWS: Update.
784 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
786 * config/texinfo.tex: Sync from upstream.
788 * bin/autom4te.in (handle_traces): Transform the `@S|@'
789 quadrigraph correctly in traces.
791 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
792 Fix typos.
794 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
795 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
796 not defined.
797 * doc/autoconf.texi (Changed Directory Variables): New node,
798 to document the whole `datarootdir' business a bit better.
799 * NEWS: Update.
800 * tests/torture.at (datarootdir workaround): Extend test.
801 Prompted by report by Alexandre Julliard.
803 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
805 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
806 when using default mode of IBM C 6 for AIX. Problem and two-line
807 fix reported by Larry Jones.
809 2006-06-22 Alexandre Julliard <julliard@winehq.org>
811 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
812 about literal '${datarootdir}' if a definition is found in the
813 output file.
815 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
817 * NEWS: Use "M4" rather than "m4" when appropriate.
818 Problem reported by Eric Blake.
819 * doc/autoconf.texi: Likewise.
820 Use @acronym around BSD, GCC, and GNU when appropriate.
821 (Why GNU M4): Renamed from "Why GNU m4".
822 (Redefined M4 Macros): Mention that Posix
823 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
824 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
825 to int.
827 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
829 * bin/autom4te.in (handle_output): Do not forbid the empty
830 pattern.
831 * tests/tools.at (autoconf: the empty token): New test.
833 2006-06-20 Stepan Kasal <kasal@ucw.cz>
835 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
836 calls, so that we do not care whether they are LIFO or FIFO;
837 in the m4_wrap, do not check which diversion is the topmost
838 one, just check that the stack is balanced at the end.
839 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
840 base diversion forever--pop the previous diversion before
841 opening the new one; consequently, remove the m4_wrap call.
842 * lib/autotest/general.m4 (AT_INIT): Likewise.
843 * tests/m4sugar.at: Do not use
844 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
846 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
847 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
849 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
850 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
851 Rework example of m4wrap token-pasting trouble so that it doesn't
852 care whether it's LIFO or FIFO.
853 Fix some "contrary to"s that are awkward in English.
855 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
857 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
858 to `yes' instead of `int$1_t' if the type is found, for more
859 consistent configure output (where $1 is the number of bits).
860 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
861 Suggested by Bruno Haible.
863 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
864 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
865 with system headers. Report by Bruno Haible.
867 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
869 * config/config.guess, config/config.sub: Sync from upstream.
871 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
872 in order to avoid picking up an older installed frozen m4sh.m4f.
873 Besides an outdated shell startup, this could have been created
874 by an earlier M4 version with incompatible frozen file format.
876 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
878 * README: Recommend m4 1.4.4 instead of 1.4.3..
879 * doc/autoconf.texi: Likewise.
880 (Special Chars in Names): Say that $(.FOO) is portable, as
881 suggested by Stepan Kasal.
882 (Installation Directory Variables, Build Directories):
883 (Automatic Remaking, Subdirectories, Fortran Compiler):
884 (Making testsuite Scripts, Defining Directories):
885 Quote variable usages better.
886 (Making testsuite Scripts): Add clean-local rule to makefile
887 snippet, by Eric Blake.
888 (Installation Directory Variables): Fix table item font.
889 Reword slightly to clarify. Generalize advice about
890 not using special characters to include all file-related
891 vars, not just VPATH.
892 (Special Chars in Variables): Warn about special characters in
893 $(srcdir) too.
894 (Assignments): Clarify default-value example as suggested by
895 Ralf Wildenhues in
896 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
897 (Special Shell Variables): Note leading ./ or ../, as suggested
898 by Eric Blake.
899 (Limitations of Builtins): Under cd, warn about CDPATH.
900 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
901 Ralf Wildenhues.
903 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
905 * doc/autoconf.texi (Configuration Actions): Remove duplicate
906 `@var', for texi2html.
907 (Systemology): Some more word wrapping, for DVI output.
908 (autom4te Invocation): The short option for `--melt' is `-M',
909 not `-m'.
911 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
913 * doc/autoconf.texi: More formatting and English tweaks,
914 many suggested by Ralf Wildenhues.
915 Reword to avoid "@code{...}'s" and the like, since it's ugly
916 with Emacs info mode. discontents -> woes.
917 Put a few "will"s back. time stamp -> timestamp.
918 side-effect -> side effect.
920 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
922 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
923 Warn about $@ not persisting. Problem reported by Julien Danjou in
924 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
925 (Special Chars in Names): Renamed from Leading _ in Macro Names.
926 Mention other special chars, too.
928 2006-06-14 Eric Blake <ebb9@byu.net>
930 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
932 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
934 * doc/autoconf.texi: Some systematic minor improvements, as
935 follows. Use "makefile" when talking about makefiles
936 generally (which might be named "makefile" or "Makefile" or even
937 "foo.mk"), "Makefile" when talking about a specific makefile
938 called "Makefile". This unclutters the text from weird quotes
939 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
940 values" rather than "@var{foo}s" and similar constructs containing
941 "}s". Use "Make rules" rather than "Makefile rules". Minor
942 English-language improvements. Change the prefix "sub-" to "sub"
943 and "re-" to "re".
944 Put blank lines around examples more consistently.
945 Avoid "rather" and "very" as intensifiers.
946 Avoid "will" as an auxiliary.
947 (Limitations of Make): Split this node into....
948 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
949 (Leading _ in Macro Names, Backslash-Newline-Newline):
950 (Backslash-Newline Comments, Long Lines in Makefiles):
951 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
952 (obj/ and Make, make -k Status, VPATH and Make):
953 (VPATH and Double-colon, $< in Explicit Rules):
954 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
955 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
956 New nodes, resulting from splitup of Limitations of Make.
957 All cross-references changed. Raise the top node from
958 a section to a chapter, and all subnodes accordingly.
959 Redo the introductory wording to match the new organization.
960 (Installation Directory Variables): Use an example that is
961 closer to what Autoconf actually does. Mention that VPATH's
962 value should not contain metacharacters or white space.
963 (Fortran Compiler): Fix a VPATH bug in an example.
964 (Leading _ in Macro Names): Mention that this problem is no longer
965 of practical concern.
966 (VPATH and Make): Reword the advice to make it clearer
967 that Autoconf and Automake support VPATH in non-GNU make, but
968 many packages have bugs in this area.
969 ($< in Explicit Rules): Refer to Build Directories rather
970 than using a (non-VPATH-safe) example.
971 (Automatic Rule Rewriting): Mention the sort of disaster that
972 can ensue with Solaris-style rule rewriting with VPATH.
974 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
976 * doc/install.texi (Compilers and Options): Weaken the
977 suggestion to use GNU make for VPATH builds.
979 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
980 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
982 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
983 in regular expression.
985 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
987 * doc/autoconf.texi (Installation Directory Variables):
988 Drop extra @samp from `@table @samp' item.
989 (Limitations of Usual Tools): Comment fix.
990 Do not nest @samp just to point to other table items.
991 (Writing testsuite.at) <AT_CHECK>: The second argument to
992 `@dvar' is already @samp'ed.
993 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
994 do not use @var in the second argument.
996 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
998 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
999 $as_shell.exe too. Problem reported by Andreas Buening in
1000 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1002 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1004 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1005 `unused variable' compiler warning, for `-Wall -Werror'.
1006 Reported by Jaap Haitsma in
1007 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1009 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1011 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1012 case the compiler dumps core. Problem reported for
1013 OpenServer 5.0.7 by Tim Rice in
1014 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1015 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1016 Likewise.
1018 2006-06-06 Tim Rice <tim@multitalents.net>.
1020 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1021 "ERROR" only shows up in "make check" output if there is an
1022 error.
1024 2006-06-06 Eric Blake <ebb9@byu.net>
1026 * tests/tools.at (automatically allowed tokens): Fix typo.
1028 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1030 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1032 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1033 typically overflows on x86 CPUs, even though the C standard
1034 requires otherwise.
1036 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1038 * configure.ac (AC_INIT): Bump to 2.59e.
1039 * NEWS: Update.
1041 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1043 Version 2.59d.
1045 * config/texinfo.tex: Sync from upstream.
1047 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1048 seen, invoke libtoolize with `--ltdl' argument.
1049 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1050 * NEWS: Update.
1051 Suggested by Eric Blake.
1053 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1055 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1056 reported by Ralf Wildenhues.
1057 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
1059 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1063 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1065 * doc/autoconf.texi: Modernize some of the references to Solaris.
1067 2006-06-05 Stepan Kasal <kasal@ucw.cz>
1069 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
1070 message issued by AC_REQUIRE.
1071 * tests/m4sugar.at: Check m4_require's error message.
1072 * tests/base.at: Check AC_REQUIRE's error message.
1073 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1074 to...
1075 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1076 AT_CHECK_M4.
1077 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1078 `expout' as the last parameter.
1079 * tests/tools.at: Adapt to the above change.
1081 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1083 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1084 information about race-free implementations of mkdir.

1090 * bin/autom4te.in (help): Likewise.
1091 * doc/autoconf.texi (autom4te Invocation): Likewise.
1093 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1095 * NEWS: GNU make now recommended for VPATH builds.
1096 Mention that some macros are now documented to be obsolescent.
1097 * doc/autoconf.texi:
1098 Prefer "current" to "modern" to describe
1099 currently-used (albeit perhaps old-fashioned) hosts.
1100 Mention which ancient features no longer need to be worried about.
1101 setgid -> set-group-ID
1102 setuid -> set-user-ID (these are the Posix terms)
1103 Fix some misuses of "only".
1104 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1105 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1106 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1107 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1108 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1109 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1110 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1111 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1112 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1113 Mention that these macros are obsolescent.
1114 (Installation Directory Variables): shall -> should
1115 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1116 Mention that it's now safe to use 3 and 4.
1117 (Limitations of Usual Tools): cp -r is now specified by Posix.
1118 Omit longwinded and obsolescent discussion of cp -f.
1119 Modernize discussion of expr, ls.
1120 (Limitations of Make): Modernize discussion of VPATH builds.
1121 Mention $? as a workaround in some cases.
1122 * doc/install.texi (Basic Installation):
1123 Mention "./configure; make; make install" first. Be more
1124 specific about why this file is generic. Remove unnecessary
1125 parens. Remove misleading "only". Remove obsolete advice
1126 about csh. Don't say "configure" takes awhile; say it
1127 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1128 and CC=c99 rather than CC=c89, as these are blessed by current
1129 Posix. Recommend GNU make if doing a VPATH build.
1131 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1133 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1134 examples involving shell prompts.
1136 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1137 and Paul Eggert <eggert@cs.ucla.edu>
1139 * doc/autoconf.texi (Here-Documents): Add details about the
1140 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1141 use "here-documents" instead of "here documents".
1143 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1145 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1147 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1149 * doc/autoconf.texi (File System Conventions): Warn about ":"
1150 anywhere in directory names.
1152 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1154 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1155 about quoting the case statement, just in case.
1156 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1157 was fixed in ksh93g; reported by Ralf Wildenhues.
1159 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1161 * doc/autoconf.texi (System Services): Do not document
1162 overriding EXEEXT via ac_cv_exeext=ext.
1163 (Particular Programs) <AC_PROG_MKDIR_P>:
1164 Document that ${MKDIR_P} understands --.
1165 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1166 comment.
1168 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1170 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1171 argument with leading hyphen. Problem reported by Paul Eggert.
1173 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1175 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1176 about quoting ac_try: quote all of it, if any of it seems suspicious.
1177 This means we don't have to worry about ${ or sed any more.
1178 Also, double-quote the case statement, to work around misuses via
1179 underquoting as reported by Ralf Wildenhues in
1180 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1181 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1182 undocumented and dangerous macro.
1183 Problem reported by Ralf Wildenhues in
1184 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1186 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1188 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1189 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1190 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1192 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1194 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1195 since evidently some packages rely on the old, broken behavior.
1196 Problem reported by Ralf Wildenhues in
1197 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1198 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1199 pre-2006-05-26 definitions, but leave in the comments that
1200 these macros are dangerous and should not be used.
1201 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1202 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1203 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1204 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1205 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1207 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1209 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1210 the use of 'tr', since this is our only use of 'tr'.
1212 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1213 and Paul Eggert <eggert@cs.ucla.edu>
1215 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1216 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1218 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1220 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1221 the output file in the `${datarootdir}' test.
1223 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1224 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1226 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1227 mention of `datarootdir' in the input file(s), but literal
1228 `${datarootdir}' in the output file, and we haven't warned yet,
1229 then warn as well: the user may have (erroneously) used
1230 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1231 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1232 * tests/torture.at (datarootdir workaround): Extend this test.
1233 * NEWS: Update.
1235 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1236 and Paul Eggert <eggert@cs.ucla.edu>
1238 * doc/autoconf.texi (autoheader Invocation): The first argument to
1239 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1240 alternatives and clear up the language a bit.
1242 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1244 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1245 ac_config_guess, ac_config_sub, ac_configure.
1246 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1247 Fix typo that prevented an unnecessary space from being removed.
1248 Problems reported by Ralf Wildenhues in:
1249 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1251 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1253 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1254 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
1255 Don't use the term "thread-safe" to talk about mkdir race
1256 conditions, since the problem is more a process than a thread
1257 issue. Problem reported by Stepan Kasal in:
1258 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
1259 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
1260 the test for 'install' more closely. Look at MKDIR_P first.
1261 Look in the PATH, and at /opt/sfw/bin.
1262 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1263 Don't bother to try mkdir -p, since we already check mkdir --version;
1264 just look at the version number. (There's no easy way to check
1265 for race-free implementations.)
1266 * tests/tools.at (autoconf: subdirectories): Adjust to above
1267 changes, since MKDIR_P now might end in "/mkdir -p".
1269 * doc/autoconf.texi (autoheader Invocation): Mention that the
1270 first arg of AC_DEFINE_UNQUOTED must be a literal.
1271 Problem reported by Ben Pfaff in
1272 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1274 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1275 * doc/autoconf.texi (Special Chars in Variables): New section.
1276 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1277 (Installation Directory Variables): Quote $(datadir) better.
1278 (Limitations of Builtins): Describe some of eval's trickiness.
1280 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1281 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1282 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1283 in front of every arg, not just trailing args. Quote apostrophes.
1284 (_AC_EVAL_ECHO): New macro.
1285 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1286 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1287 removed.
1288 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1289 exposed by quoting of eval argument. Put the command on line line
1290 so it logs better.
1291 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1292 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1293 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1294 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1295 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1296 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1297 Use eval more safely.
1298 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1299 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1300 to be replaced.
1301 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1302 lines, exposed by quoting of eval argument.
1304 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1305 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1307 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1308 initialization of `ac_cv_exeext', do not override it if it was
1309 already set, unless it was set to `no', for compatibility with
1310 Autoconf-2.13, and comment this.
1311 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1312 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1313 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1314 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1315 Document that this test may be overridden by setting
1316 `ac_cv_exeext'.
1318 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1320 Revert these two patches:
1322 2006-04-06 Eric Blake <ebb9@byu.net>
1323 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1324 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1325 2006-04-01.
1327 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1328 Clean up _AC_COMPILER_EXEEXT* macros.
1329 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1330 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1331 ac_file to the name of the default output file and call
1332 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1333 initial `rm' of the candidate files...
1334 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1335 the same list in subsequent `rm' calls, and for the temporary
1336 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1337 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1338 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1339 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1340 no longer needed) by libtool. Make it a cache check.
1341 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1342 copied here by mistake.
1343 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1344 _AC_COMPILER_EXEEXT.
1345 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1346 _AC_COMPILER_OBJEXT directly.
1347 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1349 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1351 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1352 Fix description of how the buggy `sed' works.
1354 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1356 Sync from Automake:
1358 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1359 ENOLCK. Only mention `make -j' when applicable. Only raise
1360 fatal errors when `make -j' is involved. Improve error message.
1362 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1364 * doc/autoconf.texi (Here-Documents): We now know more about
1365 the variable expansion in here documents bug.
1366 Thanks to Tim Rice and Stepan Kasal.
1368 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1369 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1371 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1373 * tests/autotest.at (Multiline command from M4 expansion):
1374 No failure to be expected if the shell quotes newlines in
1375 commands in the `set -x' output. Report by Tim Rice.
1376 * THANKS: Update.
1378 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1380 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1381 expansion in the here-documents used by config.status, as that
1382 runs afoul of the Korn shell version M-12/28/93d bug described in
1383 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1384 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1385 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1387 2006-05-23 Jim Meyering <jim@meyering.net>
1389 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1390 Fix typo introduced with 2006-04-02 change. It reversed the sense
1391 of the test.
1393 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1395 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1396 ac_dB slightly, to save bytes in the script.
1397 Max out at 50 lines, rather than 96; this is more likely
1398 (though not guaranteed) to avoid obscure 'sed' failures.
1400 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1402 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
1403 `tr -d -' as bad option argument. Work around this by deleting
1404 an unrelated character.
1405 Report by Tim Rice <tim@multitalents.net>.
1407 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
1408 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1409 Stepan Kasal <kasal@ucw.cz>
1411 * doc/autoconf.texi (Particular Programs): Do not promise that
1412 we always prefer the GNU version of the program, and that we
1413 search according to PATH; both rules can have exceptions.
1414 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
1415 AC_PROG_SED. Move descriptions of limitations
1416 to the Limitations of Usual Tools section.
1417 (Limitations of Usual Tools) <sed>: Mention script length
1418 limitations with Solaris /usr/ucb/sed.
1419 <grep>: Fix wording for empty alternative. Mention that -c and
1420 -l should not be combined, and that -E and -F should not be
1421 combined.
1423 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1424 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1426 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
1427 limits in Solaris 8 /usr/ucb/sed by testing a long script.
1429 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1431 * doc/autoconf.texi (Defining Symbols): Literal parameter of
1432 AC_DEFINE is now passed to m4_pattern_allow.
1433 * NEWS: Mention that; likewise for AC_SUBST.
1434 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
1435 the parameter to m4_pattern_allow.
1436 * tests/tools.at: Add a check for that.
1438 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1440 * lib/autoconf/status.m4: Fix typos.
1442 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1444 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1445 only the files that this macro generates.
1447 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1449 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1450 the HP-UX sed limitation of 99 commands, labels do not count.
1451 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1452 in the comment.
1453 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1455 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1457 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1458 Import the following fix from coreutils:
1460 2006-01-13 Jim Meyering <jim@meyering.net>
1462 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1463 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1464 not double-quote uses of that variable, to accommodate the rare
1465 case in which getmntent is available in none of the libraries
1466 checked. This happens at least on FreeBSD 5.0.
1468 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1470 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
1471 ac_config_guess, ac_config_sub, and ac_configure, since evidently
1472 some other programs unwisely rely on these undocumented vars.
1473 But put in warning comments about them.
1474 Problem reported by Ralf Wildenhues in
1475 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
1476 * NEWS: Document that these variables are intended to go away.
1478 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1480 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
1481 and set the language to C++ (analogous to the equivalent Fortran
1482 tests).
1484 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
1485 * doc/autoconf.texi (C++ Compiler): Document it.
1486 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
1487 * NEWS: Update.
1489 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1491 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
1492 that caused config.status to generate 100-command sed scripts; the
1493 portable limit is 99.
1495 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1497 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
1498 variable `ac_d' instead of `d' to avoid infringing namespace.
1499 Report by Ralf Menzel.
1501 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
1503 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
1504 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
1505 * tests/tools.at (autoconf: subdirectories): New test, taken from
1506 the corresponding problem report by Ralf Wildenhues in:
1507 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
1509 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
1510 Quote some uses of shell variables if they might suffer unexpected
1511 globbing. This doesn't fix all instances of quoting problems that
1512 I found, just the easy ones that look safe.
1513 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
1514 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
1515 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
1516 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
1517 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
1518 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
1519 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
1520 Likewise.
1521 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
1522 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
1524 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1526 * bin/autoreconf.in ($help): Reword according to the manual.
1527 Suggested by Olly Betts.
1529 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
1530 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1532 * bin/autoreconf.in: Pass the directory argument to
1533 `require_configure_ac'. Fix comment.
1534 * tests/torture.at (Configuring subdirectories): Expose this.
1535 Reported by Olly Betts.
1537 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1539 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
1540 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
1541 Automake as follows:
1543 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
1544 `$configure_in' instead of `configure.in', to preserve
1545 directory component.
1547 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1549 * config/config.guess, config/config.sub, config/texinfo.tex,
1550 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
1552 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1554 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
1555 test for C99 conformance; (bool) 0.5 is an integer constant
1556 expression, but (bool) -0.5 is not. Problem reported by Fedor
1557 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
1559 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1561 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
1562 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
1563 Warn about obsolete install-sh files. Remove stray sentence
1564 fragment and fix cross reference.
1565 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
1566 install -d; this undoes the 2006-05-10 change.
1567 (MKDIR_P): Mark with AN_MAKEVAR.
1568 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
1569 that we don't require $INSTALL to be thread-safe. Move comments
1570 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
1571 of AC_PROG_INSTALL. Output a message saying that we're checking
1572 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
1573 MKDIR_P instead of AC_SUBST.
1574 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
1575 Special magic for MKDIR_P, too.
1576 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
1577 a dnl.
1578 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
1580 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1582 Sync from Automake, as follows:
1584 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1585 * config/install-sh: Initialize IFS, so field splitting isn't
1586 turned off later.
1587 * config/mkinstalldirs: Likewise.
1588 * config/missing: Remove superfluous quotes. Replace all uses of
1589 `[' by `test', for consistency, and for..
1590 * config/missing (sed_minuso, sed_output): New variables.
1591 (autom4te, help2man, makeinfo): Use them. Unifies detection of
1592 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
1593 Fixes `missing' to detect `--output' for help2man. Fixes
1594 PR automake/483. Report by Dennis J. Linse.
1595 (autom4te): Document in `missing --help'.
1597 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1599 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1600 * config/install-sh: Don't use 'path' to talk about file names,
1601 as per GNU coding standards. Close a race condition reported by Ralf
1602 Wildenhues and Stepan Kasal. There is still a race condition
1603 on hosts that predate Posix 1003.1-1992, but we can't help this.
1604 Don't mishandle weird characters like space on pre-Posix hosts.
1605 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1606 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1607 AC_PROG_MKDIR_P from AS_MKDIR_P.
1608 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1609 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1610 earlier editions are not (including Automake 1.8.3).
1611 Do not suggest mkinstalldirs for thread-safety.
1612 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1613 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1614 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1615 presence of special characters and race conditions.
1616 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
1617 in Autoconf's name space.
1619 2006-05-10 Bruno Haible <bruno@clisp.org>
1620 and Paul Eggert <eggert@cs.ucla.edu>
1622 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
1623 from Automake with minor changes.
1624 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
1626 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1628 * config/install-sh: Update to Automake CVS version, as follows:
1629 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1630 * lib/install-sh: Simplify the expr implementation of dirname.
1631 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
1632 * lib/install-sh: Handle --, and diagnose unknown options.
1634 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1636 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
1637 `./autom4te' to create `./testsuite', since the `all' target
1638 will ensure its presence, but `installcheck' should not create
1639 the uninstalled wrappers.
1641 * tests/torture.at (Unusual Automake input files): Skip if we
1642 detect automake < 1.8.
1644 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1646 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
1647 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
1648 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
1649 * NEWS: Update.
1651 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1653 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1654 munge (multiple) white space and other oddities.
1655 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1656 single quotes in variable assignment.
1657 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1658 and similar failures by adding multiple spaces, tabs, and other
1659 special characters.
1660 Report and different test suggested by Francesco Romani
1661 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1663 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1664 single quotes, we only need to search for single quotes; this
1665 both simplifies the search pattern, and makes us less
1666 susceptible to `echo' variations for arguments not containing
1667 single quotes.
1668 (_AC_ARG_VAR_VALIDATE): Likewise.
1670 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1672 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1673 `$*' and IFS concatenation issue with traditional shells and
1674 bash-2.04. Report by Seanster@Seanster.com.
1676 2006-05-03 Bruno Haible <bruno@clisp.org>
1678 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1679 precisely which Mac OS X versions have the od problem.
1681 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1683 * doc/autoconf.texi: Use @option systematically.
1685 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1686 and Bruno Haible <bruno@clisp.org>
1688 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1689 about 'od'.
1690 (Integer Overflow): Mention the special case of integer division
1691 overflow.
1693 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1695 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1696 traditional shells like the Solaris one that do not use the
1697 first IFS character for assembling `$*'.
1698 Prompted by a related report from autoconf_bug@nro.ca.
1700 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1701 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1703 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1704 Mention more problems with the -e option.
1706 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1708 * NEWS: Typo.
1709 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1711 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1712 in URLs to improve DVI formatted output (requires texinfo 4.6).
1713 (System Services, Systemology, Shellology): Likewise.
1714 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1715 output.
1717 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1718 continuous text.
1719 (Runtime): Fix macro argument names to match description:
1720 `action-if-found' -> `action-if-true' and similarly.
1721 (Obsolete Macros): Likewise.
1722 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1723 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1724 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1726 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1728 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1730 * ChangeLog: Typo.
1731 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1732 DVI output.
1734 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1743 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
1744 (Integer Overflow, Null Pointers, Buffer Overruns):
1745 (Floating Point Portability, Exiting Portably): New sections.
1746 (Writing Test Programs): Fix some langauge. Recommend exiting
1747 with status 1, not merely nonzero. Clarify exit declaration.
1748 (Run Time): Move C exit status stuff to new Exiting Portably section.
1749 (Systemology): Mention Posix and levenez. Update v7 reference.
1750 (Portable Shell): Mention the Posix shell.
1752 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1754 * bin/autoconf.as (me): Replace by as_me.
1756 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1758 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1759 since as_me isn't set yet.
1761 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1763 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1764 a few minor bugs in this area.
1766 * doc/autoconf.texi (Programming in M4sh): Comment out the
1767 documentation of AS_BASENAME, for now.
1768 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1769 (Limitations of Builtins) <basename>: Do not refer to
1770 AS_BASENAME.
1771 * bin/autoconf.as (me): Don't use AS_BASENAME.
1772 (dir): Remove the unused variable.
1773 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
1774 AS_DETECT_REQUIRED. All uses changed.
1775 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
1776 All uses changed.
1777 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
1778 (AS_BASENAME): Use "basename --" to protect against leading "-".
1779 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
1780 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1781 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
1782 (_AS_DIRNAME_PREPARE): Likewise.
1783 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
1784 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
1785 (AS_DIRNAME): Use "dirname --".
1787 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1789 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1790 of "run time" and "run-time" changed to "runtime", for consistency.
1791 * lib/autoconf/fortran.m4: Likewise (in comment).

1793 * lib/autoconf/general.m4: Likewise.
1794 * lib/autoconf/headers.m4: Likewise.

1797 with more accuracy and detail.
1799 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1801 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1802 Archive is not officially `GNU' any more. Update URL.
1803 (Defining Directories): Likewise
1804 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1806 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1808 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1809 newline from the `trap' code to finish `config.log'; the NetBSD
1810 /bin/sh resets the exit status after an empty command, as
1811 documented in doc/autoconf.texi.
1812 Reported by Dalibor Topic <robilad@kaffe.org>.
1814 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1816 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1817 Suggested by Bruno Haible.
1819 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1821 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1822 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1823 Instead, just list the shells that we know work.
1824 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1825 changed. Be more cautious about the _cv_ variable.
1826 * tests/tools.at (Syntax of the shell scripts): Check the
1827 _cv_ variable once, at first, to avoid an internal autoconf error
1828 when sh -n does not work.
1830 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1832 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1834 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1836 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1837 use ">&-" since we're only 99.999% sure that this is portable,
1838 and since the MinGW bug is fixed in a different way.
1839 * lib/autotest/general.m4 (AT_INIT): Likewise.
1841 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1843 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1844 before opening config.log, to avoid hitting a bug on MinGW.
1846 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1848 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1849 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1850 This works around a MinGW bug reported by Eric Paire.
1851 Make sure that all writes to the log file append to it,
1852 rather than possibly losing data.
1853 * lib/autotest/general.m4 (AT_INIT): Likewise.
1855 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1857 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1858 description.
1860 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1862 * NEWS: Update.
1864 * configure.ac (AC_INIT): Bump to 2.59d.
1866 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1868 Version 2.59c.
1870 * Makefile.maint (news-date-check): Do not require a leading `*'
1871 before the release date in NEWS.
1873 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1874 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1876 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1877 the instantiated file do not contain the string 'datarootdir'
1878 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1879 @mandir@, replace the reference '${datarootdir}' by the value.
1880 * tests/torture.at (datarootdir workaround): New test.
1881 * NEWS: Advertise this temporary fixup.
1882 Based on a patch by Bruno Haible, reported and analyzed by
1883 Paul Eggert and Noah Misch.
1885 2006-04-12 Eric Blake <ebb9@byu.net>
1887 * tests/autotest.at (Debugging a failed test): Fix comment.
1889 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1891 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1892 all the changes since 2006-04-07.
1894 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1896 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1897 succeeded, but `ln -s file dir' failed, take care to remove the
1898 leftover target before the next test, to prevent its spurious
1899 failure; also make sure `ln file dir' works before selecting it.
1900 Thanks to Keith Marshall for pointing this out.
1901 * THANKS: Update.
1903 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1904 assignments in `at_debug_args', so that we put them correctly
1905 in the `run' script.
1906 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1907 Reported by Eric Blake.
1909 2006-04-11 Eric Blake <ebb9@byu.net>
1911 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1912 top-level tests after micro-suite has been run. Used in...
1913 (Debugging a successful test, Debugging script and environment),
1914 (Debugging a failed test): ...these new tests. The first of these
1915 is fixed by...
1916 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1917 macro, split out from...
1918 (AT_INIT): ...here, so that using -d also generates a run script.
1919 Document that -d inhibits top-level logging.
1920 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1921 inhibits top-level logging; debug scripts are created.
1923 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1924 check.
1925 * tests/autotest.at (Empty test, Empty check): New test to check it.
1927 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1928 from gcc.
1930 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1932 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1933 the files if a problem appears. Make the empty *.at files
1934 read-only, too. Proposed by Ralf Wildenhues.
1936 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1938 * config/Makefile.am: Add comment to force updated Makefile.in.
1940 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1941 space only patch to this file, this patch causes the Makefile.in
1942 files that include freeze.mk to be updated, and thus have a
1943 newer time stamp again, which in turn makes a pristine CVS
1944 checkout have correct time stamps.
1946 * Makefile.maint (cvs-sv): New macro, to be used..
1947 (config.guess-url_prefix, config.sub-url_prefix)
1948 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1949 point to CVS text checkout of Gnulib files.
1950 (copyright-check): Bump current year.
1951 (announcement): Do not hard-wire `./announce-gen'.
1952 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1953 correctly.
1954 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1955 `chmod +x'.
1956 (wget_files): Update config.guess, config.sub, texinfo.tex by
1957 `wget-update', now that their URLs work again.
1959 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1961 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1962 Problem noted by Paul D. Smith.
1964 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1966 * doc/autoconf.texi: Remove unused words from word list.
1967 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1968 .x-sc_trailing_space: New files.
1970 * doc/standards.texi: Sync from gnulib.
1972 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1973 `LIBOBJDIR' as experimental.
1975 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1976 with a target directory; it's internally implemented as `cp'
1977 anyway, but since Autoconf advertises the possibility to use
1978 a target directory when LN_S is `ln -s', we need to find out.
1979 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1980 analyzed by Keith Marshall <keith.marshall@total.com>.
1982 * THANKS: Update.
1984 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1986 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1987 confdefs.h as-is. In general, if it has backslash-newline or the
1988 like, then it doesn't work either to sort or to remove empty
1989 lines.
1991 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1993 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1995 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1997 * lib/autom4te.in (Automake-preselections): Preselect
1998 _AM_SUBST_NOTMAKE.
2000 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2002 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2003 apostrophe within a single-quoted string, as this is the usual
2004 tradition and is easier to read than '"'"'. Don't rely on the
2005 shell treating "$/" like '$/'. Use a more-consistent indenting
2006 style for the trap.
2008 2006-04-09 Eric Blake <ebb9@byu.net>
2010 * tests/autotest.at (Backquote command substitution),
2011 (Multiline backquote command substitution): Remove mistaken
2012 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2013 applied...
2014 (Parenthetical command substitution, Multiline parenthetical
2015 command substitution): here.
2017 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

2047 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2048 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2049 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2050 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2051 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2052 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2053 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2054 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2055 (Coding Style). Don't mention m4_expand_once.

2074 New macros.
2076 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
2077 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
2079 2006-04-08 Stepan Kasal <kasal@ucw.cz>
2081 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
2082 of the warning introduced by the 2001-08-28 change.
2084 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
2085 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2087 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
2088 variables shall be overriden by the cache.
2089 * tests/torture.at (AC_ARG_VAR): Test also with a first value
2090 that contains braces.
2092 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2094 Revert the patch from 2006-04-01 and only improve
2095 _AS_DETECT_BETTER_SHELL:
2097 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2098 skip nonexistent directories.
2099 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2100 only shell candidates which exist.
2101 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2102 * lib/autotest/general.m4 (AT_INIT): No need to give three
2103 parameters to _AS_PATH_WALK.
2105 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2106 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2108 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2109 distinguish m4sugar macros.
2110 * tests/tools.at (autoupdating with aclocal and m4_include):
2111 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2112 test case by Noah Misch <noah@cs.caltech.edu>.
2114 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2116 Revert my change from 2006-03-17, in other words:
2117 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2118 and DUALCASE=1.
2119 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2120 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2121 it is set.
2123 2006-04-07 Eric Blake <ebb9@byu.net>
2125 * doc/autoconf.texi (Programming in M4sh): Document that
2126 AS_MKDIR_P exits the script on failure.
2127 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2129 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2131 * config/elisp-comp, config/install-sh, config/mdate-sh,
2132 config/missing, config/mkinstalldirs: Sync from Automake.

2146 Eric Blake <ebb9@byu.net>,
2147 Paul Eggert <eggert@cs.ucla.edu>,
2148 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2150 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2151 whether `set' quotes correctly: redirect stderr of the tested
2152 `set', and use a subshell, for Ultrix; use `sed' instead of
2153 `grep' for zsh `set' which may write binary output; match only
2154 at the beginning of a line, to avoid false positives.
2155 In order to avoid false positives by unrelated variables with
2156 multiline content, put the dump algorithm in a subshell and
2157 unset all variables containing newlines (except some which are
2158 special to the shell). Warn about cache variables that are
2159 unset.
2161 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2163 * config/config.guess, config/config.sub, config/texinfo.tex:
2164 Sync from upstream.
2166 * tests/mktests.sh: Reword comments.
2168 * tests/mktests.sh: Only skip internal macros starting with
2169 `_AC_' or `__AC_'. Noted by Stepan Kasal.

2171 (AC_ARG_VAR): Do test this now.
2172 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
2173 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
2174 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
2175 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
2177 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
2178 shell issue with double-quoted command substitutions of native
2179 commands.
2180 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
2181 Marshall.
2183 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
2184 no file matches the glob, discard the warning, set `nullglob'.
2185 (syntax-check): Likewise.
2186 (sc_cast_of_x_alloc_return_value): Likewise.
2187 (sc_cast_of_alloca_return_value, sc_error_exit_success)

2189 (m4-check): Likewise.
2190 (sc_system_h_headers): Do not print rule on execution.
2191 (sc_tight_scope): Do not fail for non-existing `src' directory.
2192 (sc_changelog): Skip the Copyright footer.
2193 * lib/autoconf/lang.m4: Remove trailing space.
2195 * lib/autoconf/status.m4: More replacements to
2196 <tab><space> where this makes sense.
2198 2006-04-06 Stepan Kasal <kasal@ucw.cz>
2200 * tests/Makefile.am (maintainer-check-posix):
2201 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
2203 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
2204 ac_config_<foo>s again, sometimes normalized, sometimes not.
2205 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
2206 (AC_CONFIG_COMMANDS): Do not do so here.
2207 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
2208 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
2209 2005-07-25 rewrite. Noticed by Noah Misch.
2211 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
2212 _AC_PRESERVE_HELP_ORDER, ...
2213 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
2215 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
2216 inside m4_expand_once; it is redundant.
2218 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
2219 for --help from Cygnus `configure.'
2221 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
2223 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
2224 on a patch proposed by Ralf Wildenhues.
2226 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2228 * lib/autoconf/status.m4: Replace <space>''<tab> with
2229 <tab><space> where this makes sense.
2231 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
2232 Noah Misch <noah@cs.caltech.edu>
2234 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
2235 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
2236 * doc/autoconf.texi (Help Formatting): New node.
2237 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
2239 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2241 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
2242 lib/autoconf/specific.m4, lib/autoconf/status.m4,
2243 lib/autoconf/types.m4, lib/autotest/general.m4,
2244 tests/mktests.sh, tests/torture.at: White space cleanup:
2245 remove some SPACE before TAB, or add quoting ('' or @&t@).
2247 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
2249 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
2251 2006-04-05 Eric Blake <ebb9@byu.net>
2253 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
2254 empty test suite works.

2274 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
2275 Use 'comm' rather than N instances of grep; this also fixes a bug
2276 whereby substrings were incorrectly matched, causing us to not
2277 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
2278 (exclude_list): Exclude empty macros.
2279 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

2284 Switch from grep to awk syntax.
2285 (ac_exclude_script): Renamed from ac_exclude_egrep.

2362 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2363 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2364 ac_file to the name of the default output file and call
2365 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2366 initial `rm' of the candidate files...
2367 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2368 the same list in subsequent `rm' calls, and for the temporary
2369 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2370 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2371 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2372 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2373 no longer needed) by libtool. Make it a cache check.
2374 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2375 copied here by mistake.
2376 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2377 _AC_COMPILER_EXEEXT.
2378 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

2414 subordinate tools.
2415 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
2416 * doc/autoconf.texi (autoreconf Invocation): Document it.
2418 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

2434 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
2435 Remove stray newline in output.

2450 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2452 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
2453 switch all of them on and of when necessary. Fixes the bug when
2454 m4sugar macros (e.g., m4_define) were expanded after the first
2455 automatic update (e.g., after AC_PREREQ or AC_INIT).
2457 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

2488 (File System Conventions): Put discussion of // versus / here, and
2489 modernize it a bit.

2504 * bin/autoscan.in: The value of find_configure_ac should be
2505 checked for existence, so we don't barf over a nonexisting
2506 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
2508 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2573 (AC_CHECK_SIZEOF, AC_CHECK_SIZEOF struct): Use it.

2617 IFS even in case of empty `$PATH'.
2619 2006-03-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2621 * lib/autotest/general.m4 (AT_INIT) <at_optarg>: Optimize
2622 `expr' away if there is nothing to do.

2651 nor C89 mode, set `$ac_cv_prog_cc_stdc' to `no' instead of
2652 trying to execute the command `no'.
2654 * lib/autoconf/lang.m4 (AC_LANG_CONFTEST): AC_DEFUN this, not
2655 m4_define, so that the requirements of `AC_INCLUDES_DEFAULT' are
2656 expanded outside.
2658 * doc/autoconf.texi (autoconf Invocation): Fix typos in trace
2659 example. Do not emphasize `$%', it is hardly new and special.
2660 Reported by Edouard Bechetoille <ebecheto@ens-lyon.fr>.
2662 * doc/autoconf.texi (Limitations of Usual Tools): Document
2663 OpenBSD and traditional `grep' failure to handle multiple

2683 Use more modern terminology for which standard is what.
2684 (AC_PROG_CC): Mention gcc first, and remove obsolete references to egcs
2685 and to ansi2knr.

2690 the obsolescent AC_HEADER_STDC.
2691 (AC_FOO_IFELSE vs AC_TRY_FOO): Don't use #error; test programs

2703 doesn't. Problem reported by D'Arcy A MacIsaac and diagnosed by
2704 Ralf Wildenhues.

3173 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3174 Stepan Kasal <kasal@ucw.cz>
3176 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3177 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3178 make its content writable before removing it. Remove an errorneous
3179 comment from the end, where the logs of the failed tests are copied
3180 to the main log file.
3182 2005-09-27 Stepan Kasal <kasal@ucw.cz>
3184 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
3185 in case the computer is too quick. Double quote the configure.ac
3186 snippets.
3188 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
3189 problems if the testsuite were running too fast.
3191 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3193 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3194 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3195 (which belong to Xt, not X itself). See Debian bug 327655.
3196 * NEWS: Mention this.
3198 2005-09-07 Stepan Kasal <kasal@ucw.cz>
3200 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
3202 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
3204 * config/move-if-change: Don't output "$2 is unchanged";
3205 suggested by Ben Elliston. Handle weird characters correctly.
3207 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3209 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3210 calls, so that the final expansion of this macro is shorter.
3211 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3212 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3213 the cleanup there. Use AS_VAR_* macros, to be more general.
3214 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3216 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3218 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
3220 2005-09-01 Stepan Kasal <kasal@ucw.cz>
3222 * doc/autoconf.texi (Configuration Headers): Add an index entry
3223 for AH_HEADER.
3225 2005-08-26 Pavel Roskin <proski@gnu.org>
3227 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
3228 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
3229 running xmkmf.
3231 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
3233 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3234 The previous patch didn't work, so try a better one.
3236 2005-08-26 Stepan Kasal <kasal@ucw.cz>
3238 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3239 in the example. Reported by Bruno Haible.
3240 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3241 "if $undefined_var;" succeeds with my shell.
3243 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
3244 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
3245 but change the m4_divert_text to m4_divert_once.
3247 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
3249 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3250 Work around bug in Solaris /usr/xpg4/bin/awk.
3251 The bug is present in at least Solaris 8 through 10.
3253 2005-08-24 Stepan Kasal <kasal@ucw.cz>
3255 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
3256 some evil values and relying on the fact that $* concatenates the
3257 parameters by the first character from IFS.
3259 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3260 Stepan Kasal <kasal@ucw.cz>
3262 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
3263 first header appears, define AH_HEADER.
3264 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
3265 Update limitations about when to call AC_CONFIG_HEADERS.
3266 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3267 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3268 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3269 ``Configuration Actions''; fix their index entries.
3271 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3272 options correctly. Process N-M as M-N if M is smaller than N.
3273 Process ranges correctly so that N-N will run only N.
3274 Sort and uniquify the tests that will be run. If there is more
3275 than one test, reinsert the banners for the tests.
3276 * tests/autotest.at (Keywords): Unmark XFAIL.
3278 2005-08-23 Stepan Kasal <kasal@ucw.cz>
3280 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
3281 before passing the macro name to AH_TEMPLATE.
3283 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3284 now opens log after option processing; in particular, --version
3285 and --help do not touch config.log.
3287 * Makefile.maint: Revert the change from 2005-08-12.
3289 2005-08-22 Stepan Kasal <kasal@ucw.cz>
3291 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
3292 common code to...
3293 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
3295 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3297 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
3298 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
3299 Language cleanup.
3301 * doc/autoconf.texi (Defining Symbols, Changed Results):
3302 Prepend to LIBS, not append, in examples.
3304 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3306 When building in place, set srcdir="."; suggested by Tim Van Holder.
3308 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3309 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3310 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3311 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
3312 does not mean "no --srcdir option".
3314 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3316 * tests/autoscan.at (autoscan): New file.
3317 * tests/suite.at: Use it.
3318 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
3319 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
3321 * tests/autotest.at (Keywords): Test keywords combinations.
3323 2005-08-12 Stepan Kasal <kasal@ucw.cz>
3325 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
3326 add "2>&1"; gzip 1.2.4 prints help on stderr.
3328 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3330 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
3331 was pushdef'ed twice while popped only once. Push it only once.
3332 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
3334 2005-07-26 Stepan Kasal <kasal@ucw.cz>
3336 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
3337 prefixed by mere "===", not "configure: === ".
3339 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
3341 * Makefile.maint: Update from Bison.
3343 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3344 "<tab>" in comment, so that the point is understandable.
3346 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3348 Rewrite substantial part of lib/autoconf/status.m4.
3349 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3350 and CONFIG_COMMANDS are not processed in four separate loops.
3351 Instead, there is one main loop. This alows that the common code
3352 is expanded only once, thus config.status (and configure) is smaller.
3354 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3355 the AC_LIST_FILES and cousins macros are no longer used.
3357 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3358 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3359 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3360 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3361 contain the initialization, nor the for loop, nor the associated
3362 commands; all these go to ...
3363 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3364 _AC_OUTPUT_CONFIG_STATUS.
3365 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3366 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3367 (_AC_OUTPUT_FILE): The creation of the sed script ...
3368 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3369 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3370 _AC_OUTPUT_MAIN_LOOP.
3371 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3372 _AC_CONFIG_COMMANDS): Use ...
3373 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3374 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3375 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3376 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3377 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3378 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3379 ... new macros.
3380 (_AC_CONFIG_UNIQUE): Update.
3381 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3382 Replaced by this ...
3383 (_AC_LIST_TAGS): ... new common macro.
3384 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3385 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3386 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3387 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3388 this didn't belong to the `config commands' section.
3389 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3390 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3391 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3392 to the `config commands' section either.
3393 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3394 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3396 ... and many changes to the comments nearby.
3398 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3399 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3400 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3401 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
3402 (#define header templates): The comment at the top of the generated
3403 header now includes the name(s) of the source file(s).
3405 Several unrelated small changes:
3407 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
3408 parameter to AC_DIAGNOSE.
3409 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
3410 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
3411 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
3412 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
3413 with AU::AC_OUTPUT.
3414 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
3415 in AC_OUTPUT doesn't double-quote it either.
3416 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
3417 parameters.
3419 2005-07-10 Stepan Kasal <kasal@ucw.cz>
3421 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
3422 versions of Portland Group compiler produce single- and double-quoted
3423 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
3424 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3426 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3428 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3429 This is a corrected version of yesterday's patch.
3431 2005-07-07 Stepan Kasal <kasal@ucw.cz>
3433 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
3434 path, too; insert a "===" to emphasize the line.
3436 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
3437 ac_cv_build_alias to ac_build_alias.
3438 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3440 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3441 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3442 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3443 (AC_ARG_VAR): ... here.
3444 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3445 target_alias.
3447 Keep a list of all precious variables and process them with one simple
3448 for loop, instead of expanding all commands, or, OTOH, complicated
3449 processing of output of "set".
3450 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3451 variable names in new macro...
3452 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
3453 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
3454 a loop to assign all ac_env_* and ac_cv_env_* variables.
3455 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3456 to INIT_PREPARE.
3457 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3458 its value to shell variable ac_precious_vars and call
3459 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
3460 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
3461 _AC_ARG_VAR_VALIDATE.
3463 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
3464 and the AC_SUBSTs ...
3465 (AC_INIT): ... here.
3467 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
3468 the ac_subst_files section in config.log.
3470 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
3472 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>
3474 * NEWS: New macro AC_C_TYPEOF.
3475 * doc/autoconf.texi (C Compiler): Document AC_C_TYPEOF.

3479 Fix problems reported by Nicolas Joly.
3480 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
3481 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3482 They are generated by the Tru64 v5.1B shell.
3484 2005-07-05 Stepan Kasal <kasal@ucw.cz>
3486 Fix my changes from 2005-07-01; reported by Noah Misch.
3487 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
3488 description, the macro now accepts only a single tag.
3489 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
3491 Fix cases when the varsions of Autoconf and Autotest don't match.
3492 Reported by Noah Misch.
3493 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
3494 at_top_builddir, for compatibility with older autotest.
3495 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
3496 is not set, use at_top_builddir, for compatibility with older
3497 versions of autoconf.
3499 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
3501 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
3502 Problem reported by Patrick Welche.
3504 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
3506 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
3507 sed substitution command, so that we allow | in program prefixes
3508 and program suffixes. (& is a problem anyway; we're not fixing
3509 that here.)
3510 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
3511 configure_input, top_builddir, srcdir, etc.
3512 * lib/autotest/general.m4 (AT_INIT): Likewise, for
3513 PATH_SEPARATOR in AUTOTEST_PATH.
3515 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
3517 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
3518 for loop over config.site files using `set', to allow
3519 directory names containing IFS characters.
3521 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
3523 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
3524 directories with weird names. Apparently some people like living
3525 on the edge. However, improve the test that "pwd" actually does
3526 report a name for the working directory.
3527 * NEWS: Remove the claim that we test for funny chars in dir names.
3529 2005-07-01 Stepan Kasal <kasal@ucw.cz>
3531 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's

3541 about #include <config.h>.
3542 (Generic Functions): Mention the Gnulib project.
3543 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
3545 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
3546 document to output the default config_* lists to config.status.
3547 Don't recognize option --file, if the functionality is not there.
3548 Likewise for --header; moreover, recognize --he and --h as shortcuts
3549 for --help in that case.
3551 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
3552 matches the order of execution. No code changed.
3554 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3556 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
3557 single-quoted -cmdline argument in Portland Group compiler.
3558 Reported against LAM by Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3560 2005-06-30 Alexandre Duret-Lutz <adl@gnu.org>
3562 * lib/autom4te.in (Automake-preselections): Preselect AC_SUBST_TRACE.
3564 2005-06-29 Stepan Kasal <kasal@ucw.cz>
3566 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
3567 descriptors to child processes; reported by Norman Gray.
3569 2005-06-29 Stepan Kasal <kasal@ucw.cz>
3571 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
3573 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
3574 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
3575 (AC_SUBST): Call it.
3576 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
3577 the directory specific variables; but don't call it for configure_input.
3579 2005-06-28 Derek Price <derek@ximbiot.com>
3581 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
3582 addition.
3584 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
3586 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
3587 directory have inherent problems with special characters like spaces,
3588 due to limitations in Make syntax. Problem reported by Alexandre
3589 Duret-Lutz.
3590 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
3591 Also, fix Tru64 porting problem with shell patterns,
3592 reported by Ralf Wildenhues.

3600 * tests/local.at (AT_CHECK_ENV): Simplify regexp slightly.
3602 Fix some more shell quoting problems. Prompted by a bug report
3603 from Justace Clutter.
3604 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
3605 variable into diagnostic. Make the diagnostic an error, not a warning,
3606 because we really don't support spaces and suchlike in dir names.
3607 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3608 Don't worry about backslashes in srcdir; it can't happen now.
3609 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
3610 Simplify ac_optarg handling.
3611 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.
3613 2005-06-22 Stepan Kasal <kasal@ucw.cz>

3616 * configure.ac: Call AC_PROG_EGREP and AC_PROG_SED.
3617 * tests/atlocal.in: Propagate $EGREP and $SED.
3618 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
3619 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
3621 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
3622 that '\|' is not allowed in BREs; recommend using newline separated

3639 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
3641 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
3642 expand to the empty list. Don't use two pairs of m4_changequote,
3643 it's not necessary.

3651 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
3652 * doc/autoconf.texi:
3653 Don't mention Solaris versions so much, if a
3654 problem is common to all extant versions of Solaris. Say "SunOS
3655 4" instead of "SunOS" for SunOS 4.
3656 (awk): Mention more of the limitations of traditional Awk.

3667 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

3684 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
3685 (.x.1): Ignore the time stamp in the .TH line when deciding whether

3699 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3700 -u, since it outputs chatter if the input files are the same.
3701 Problem reported by Ralf Menzel.
3703 2005-06-08 Derek Price <derek@ximbiot.com>
3705 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3706 renaming them since they are about to be redefined anyhow.
3708 2005-06-08 Derek Price <derek@ximbiot.com>
3710 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3711 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3712 Move m4_undefine to alphabetical order.
3714 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>

3717 * doc/autoconf.texi (Introduction): Likewise.
3718 Reword to avoid some formatting glitches.

3721 Redo example output tp match current CVS snapshot.
3722 Use @example.org in email addresses when the examples
3723 might get inadvertently cut-and-pasted into user code.

3736 follows its own advice about quoting better.
3737 Reword to avoid some formatting glitches.
3738 * doc/installt.exi: Reword to avoid some formatting glitches.
3740 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3741 Tru64 ksh pattern matching bug. Reported against Libtool by
3742 Albert Chin <libtool@mlists.thewrittenword.com> and
3743 Nicolas Joly <njoly@pasteur.fr>.
3745 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3747 m4_cdr of one-member list was [[]] (one-member list containing an
3748 empty string) instead of [] (an empty list. Callers were skewed to
3749 match this misbehaviour. As a consequence of this:
3750 - m4_foreach([x], [], [foo]) expanded to `foo', while
3751 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3752 This bug has been fixed:
3754 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3755 expand to an empty string; print error msg if called without
3756 an argument list.
3757 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3758 misbehaviour; handle [] and [[]] correctly.
3760 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3762 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

3766 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3768 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3769 swallow records with more than 99 fields.
3770 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3771 parse the long line.
3773 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3775 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3776 swallow literals longer than 399. Reported by Ralf Wildenhues.
3777 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

3782 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
3783 to gfortran, and make these the first two compiler names
3784 checked (following the general autoconf preference for gcc).
3786 2005-06-03 Stepan Kasal <kasal@ucw.cz>
3788 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3789 (DISTCLEANFILES): Remove $(check_SCRIPTS).
3790 (testsuite): Make sure autotest.m4f is up-to-date before using it.

3794 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3795 expression of unbounded size when processing the --list
3796 option. This runs afoul of a limit of 399 bytes per regular
3797 expression on AIX. Problem reported by Ralf Wildenhues.
3799 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

3802 * doc/autoconf.texi (Particular Headers): Reword example
3803 for multiline stdbool replacement.

3805 give all the details about |#_!!_#|.
3806 Reword description of line replacement.
3808 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3810 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3811 now contain newlines, and substituted files must be referenced on
3812 a line alone; the sed scripts to substitute them are now very
3813 different.
3814 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3815 commands can be put in a sed script portably.
3816 * doc/autoconf.texi (Setting Output Variables): Document above
3817 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple

3829 classes in shell scripts. The test was too brittle.
3831 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3833 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3834 * doc/autoconf.texi (Limitations of Builtins): Document this
3835 limitation.
3837 2005-05-24 Stepan Kasal <kasal@ucw.cz>
3839 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
3840 common code; used in many places in the tree.

3847 messages when ac_unique_file is not found.
3848 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3849 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
3850 commands, for consistency with AC_MSG_ERROR and such.
3852 * bin/autoconf.as: Make more use of "shift 2" in option processing.

3862 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3864 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
3865 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3866 (ac_top_builddir): ... this ...
3867 (ac_top_build_prefix): ... to this; the old name is also kept, for
3868 backward compatibility.
3869 (ac_top_builddir_sub): New variable, without the trailing slash,
3870 always nonempty.
3871 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
3872 * doc/autoconf.texi (Configuration Actions): Rename

3883 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3885 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3886 argument to m4_foreach. I guess it was necessary in the past,
3887 but I think it's a no-op now.
3889 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3891 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3892 ``cat <<_ACEOF'' commands to one.
3893 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3894 * lib/autoconf/status.m4: On various places, use expr instead of
3895 ``echo|sed.''
3896 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3897 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3898 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3899 a range.
3900 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for

3906 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3907 as on 2005-05-02.

4073 2005-04-01 Stepan Kasal <kasal@ucw.cz>
4075 * doc/autoconf.texi (Generic Programs): Fix a typo.
4077 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
4079 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
4080 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
4082 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4084 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4085 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4086 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4087 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4088 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4090 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4092 * NEWS: The configure command now warns you if you attempt to use
4093 a directory whose name contains a special character like space,
4094 newline, or "\".
4095 * doc/autoconf.texi (Installation Directory Variables): Allow
4096 "," in file names. Do not use \@; it's not a portable regexp.
4097 * bin/Makefile.am (edit): Likewise.
4098 * lib/Makefile.am (edit): Likewise.
4099 * tests/Makefile.am (edit): Likewise.
4100 * tests/semantics.at: Likewise.
4101 * tests/torture.at: Likewise.
4102 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
4103 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
4104 * doc/autoconf.texi (File System Conventions): Warn about
4105 unportable file names.
4106 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4107 (AC_INIT): Use it.
4108 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4109 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4110 ac_pwd, and quote srcdir.
4111 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4113 * doc/autoconf.texi: Fix some systematic formatting problems.
4114 ".)" needs a following @: if not at the end of a sentence, and
4115 similarly for "!)". "etc." should be preceded by a comma.
4116 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4118 2005-03-22 Bruno Haible <bruno@clisp.org>
4120 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4121 argument is often called 'build-aux'.
4123 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4125 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4126 macro AC_TRY_LINK is obsolete.
4127 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4128 `AC_CONFIG_FILES'.
4130 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4132 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4133 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4134 from a Common Lisp's `cl'.
4135 (AC_PROG_CXX): Behave according to the documentation: don't
4136 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4137 make the variable CCC precious; use `cl.exe', not `cl'.
4139 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4140 Alexandre Duret-Lutz <adl@gnu.org>
4142 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4143 /dev/null, as "configure" shouldn't read stdin, and this insulates
4144 us from problems (e.g., when testing for "cl"). Also, do this
4145 redirection before invoking "hostname" or "uname", and keep the
4146 original input stream available via...
4147 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4148 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4149 bother with "</dev/null" since it's now done at the top of
4150 'configure'.
4151 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4152 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4153 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

4156 * tests/base.at (Input/Output): New test.
4158 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4160 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4161 newline if neither \c nor -n work, as that would output two
4162 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4164 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4166 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4167 This causes that any required macros inside will get before the if.
4168 * doc/autoconf.texi (autom4te.cache): A typo.
4170 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4172 Undo previous change, except keep the change to
4173 lib/autoconf/programs.m4 that replaced grep with shell
4174 pattern-matching. This is because net-snmp configure reads stdin.
4175 Reported by Noah Misch.
4177 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4179 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4180 from /dev/null, as "configure" shouldn't read stdin, and this
4181 insulates us from problems (e.g., when testing for "cl").
4182 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4183 before invoking "hostname" or "uname".
4184 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4185 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4186 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4187 "</dev/null" since it's now done at the top of 'configure'.
4188 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4189 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4190 Also, replace grep with shell pattern-matching, to save a process.
4192 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4194 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4195 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4196 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4197 compiler.
4199 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4201 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4202 grep -q isn't portable. Improve grep -s explanation.
4203 Problem reported by Dan Manthey.
4205 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4207 * doc/autoconf.texi (Special Shell Variables): Clarify
4208 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4210 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4212 * doc/autoconf.texi: Use @acronym for DJGPP.
4213 Fix some @code's that should have been @env's, and vice versa.
4214 Sort environment variable names.
4215 Mention that shells no longer inherit IFS.
4216 Don't recommend PATH_SEPARATOR=';' so strongly.
4217 Mention that $RANDOM might expand to the empty string.
4218 "symlink" and "soft link" -> "symbolic link".
4219 Improve mktemp description (reported by Bruno Haible).
4221 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
4223 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
4224 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
4225 Likewise.
4226 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
4227 Likewise.
4229 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
4231 * NEWS: Mention AT_COPYRIGHT.
4233 * tests/local.at (AT_CMP): Use diff directly on input files rather
4234 than copying them.
4236 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
4237 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
4239 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4240 and Paul Eggert <eggert@cs.ucla.edu>
4242 * tests/autotest.at (Empty test suite): New test.

4244 (Substitute a 2000-byte string, Define to a 2000-byte string)
4245 (Substitute a newline, Define a newline): New tests.
4247 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4249 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
4250 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
4251 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
4252 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
4253 (Standard regular expressions): New test.
4254 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
4255 excess test name quoting.
4256 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
4257 CPPFLAGS to `configure' instead of setting it in `configure'.
4259 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
4260 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
4261 on some platforms.
4263 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
4264 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
4266 * tests/local.at (AT_CMP): New macro.
4267 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
4268 (AC_SAVE_STATE): Move environment grep...

4270 (AT_CONFIG_CMP): New macro.
4271 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
4272 * tests/c.at (Extensions): Do not exit early.

4275 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
4276 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
4278 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
4279 (AC_COPYRIGHT): Factor header comment portion out and move into...

4292 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
4294 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
4295 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4297 Try not to generated lines of unlimited length, as POSIX places a
4298 2047-byte limit on line length of portable text files.
4299 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
4300 Use newline as a separator, not space.
4301 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
4302 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
4303 space.
4305 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4307 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
4308 as_func_*. Add test to check whether positional parameters
4309 are restored after function return.
4311 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
4313 * doc/autoconf.texi (Special Shell Variables): Mention _,
4314 BIN_SH, DUALCASE. Say that variables other than "status" are safe
4315 if they contain a lower-case letter. The DUALCASE problem was
4316 reported by Ralf Wildenhues.
4318 * bin/autoconf.as: Don't exit with status 0 after write failure
4319 with --help or --version.
4320 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
4321 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.

4325 * doc/autoconf.texi (Limitations of Usual Tools):
4326 Unicos 9 sed limitations.
4327 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
4328 to get the option-enhanced interface on older Crays. Try ftn for
4329 Fortran 95 (newer Crays).
4331 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
4333 * man/Makefile.am (.x.1): Go back to the simple solution, but take
4334 care to echo the commands, so the user knows what's going on.
4335 Modified from a suggestion by Stepan Kasal.
4337 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
4338 with a cross reference. Derived from a suggestion by Bruce Korb.
4340 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
4342 * doc/autoconf.texi (config.status Invocation): Warn about
4343 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
4344 * doc/install.texi (Defining Variables): Likewise.
4345 Based on a proposed patch by Ralf Wildenhues.
4347 * man/Makefile.am (.x.1): Make sure the required generated files
4348 are up to date. Problem and original solution proposed by Stepan Kasal.
4349 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
4350 implicit-man-prerequisites): New rules, used by the above.

4356 2005-01-29 Stepan Kasal <kasal@ucw.cz>
4358 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4359 Update the long comment explaining it.
4361 m4_require no longer writes an ``is required by'' line to the
4362 execution stack. It contains only one bit of non-redundant
4363 information: that the macro was required, not called. And even
4364 this bit is useless in most situations: have you ever met a macro
4365 which both calls and requires the same macro?
4367 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4368 (_m4_defun_pro_outer): ... only via this macro, for the outermost
4369 macro.
4370 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
4371 (m4_expansion_stack_pop): Remove the misplaced comment.
4372 (m4_require): Don't put the ``is required by'' line to the
4373 execution stack; slightly improve the out-of-a-defun error message.
4374 (_m4_divert_grow): New macro, counter for the temporary diversions.
4375 (_m4_require_call): Use it.
4376 * tests/m4sugar.at (m4_require): Expect output without the
4377 ``is required by'' messages.
4379 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4381 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4382 rather than x for expr.
4384 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
4385 this is safe.
4386 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
4387 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

4396 * doc/make-stds.texi, doc/standards.texi: Update from masters.
4397 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
4398 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
4399 from masters, so that FileUtils.pm's update_file provide --force
4400 support.
4401 * bin/autoheader.in: Pass $force to update_file so that
4402 config.h.in is always recreated when --force.
4404 2005-01-24 Stepan Kasal <kasal@ucw.cz>
4406 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
4408 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
4410 * doc/autoconf.texi (Limitations of Builtins): Clarify that
4411 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
4413 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
4415 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
4416 Warn about newline stripping in `` and $(). Update Solaris
4417 version to 9.
4418 (Limitations of Builtins): Use expr "X...", not expr "x...", as
4419 X insulates us from future changes to Posix.
4420 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
4421 stripping.
4423 2005-01-19 Stepan Kasal <kasal@ucw.cz>
4425 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
4426 you cannot use AC_DEFINE to define macros containing `[' or `]'.
4428 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
4430 * doc/autoconf.texi (Limitations of Usual Tools): Document bug
4431 in Solaris 8 join. Problem reported by Tomohiro Suzuki on
4432 bug-tar mailing list.

4438 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
4440 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C)): Declare longval and
4441 ulongval to be static, to avoid unwanted GCC warning. Problem
4442 reported by Michael Jennings via Daniel Reed; see
4443 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
4445 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
4447 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
4448 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
4449 datadir, infodir, and mandir. Adjust argument parsing code.
4450 (_AC_INIT_HELP): Update help text.
4451 * doc/autoconf.texi (Installation Directory Variables): Document
4452 new variables.
4454 2005-01-04 Noah Misch <noah@cs.caltech.edu>
4456 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
4457 not seem to work, assume it does set $(MAKE).
4458 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
4460 2005-01-03 Stepan Kasal <kasal@ucw.cz>
4462 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.
4464 2005-01-03 Stepan Kasal <kasal@ucw.cz>
4466 A cleanup of the diversion support in m4sugar.
4468 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
4469 (_m4_divert_n_stack): New macro; the expansion is
4470 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
4471 otherwise.
4472 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
4473 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
4474 stored in _m4_divert_diversion or _m4_divert_dump.
4475 (m4_divert_pop): When the parameter is given, compare the symbolic
4476 name with the last diversion pushed on the stack. Previously, the
4477 current diversion was compared with the numeric value of the
4478 diversion given as the parameter.
4479 (m4_require): If the macro hasn't been expanded yet, call ...
4480 (_m4_require_call): this new macro.
4482 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4484 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_ARG_VAR_VALIDATE):

4787 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4788 "char c = '\200';" rather than "char c = 0x80;" as the

4790 overflow on signed char hosts.
4792 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
4793 to -qlanglvl=ansi. We don't want to disable extensions.

4906 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4907 "/usr/include", clear ac_x_includes instead of leaving it as "no"

4977 * bin/autoconf.as (autom4te_options): New var.
4978 Use it instead of appending to AUTOM4TE, so that we can allow
4979 spaces in the build directory's absolute name.
4980 * bin/autoheader.in ($autoconf): Allow spaces in file names.
4981 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
4982 AT_CHECK_NOESCAPE): Likewise.
4983 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
4984 main program): Likewise.
4986 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
4988 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
4989 From Ralf Corsepius in:
4990 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
4992 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
4994 * doc/autoconf.texi (Function Portability): Document isinf and
4995 and isnan. From a suggestion by Kevin Ryde.
4997 * lib/Autom4te/General.pm (END): Return correct exit status even
4998 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5000 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5002 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5003 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5004 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5006 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5008 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5009 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5010 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5011 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5012 * lib/autom4te.in (Automake-preselections): Preselect
5013 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5015 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5017 * lib/autom4te.in (Automake-preselections): Preselect
5018 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5019 trace them.
5021 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5023 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5024 Tru64.
5025 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5026 Document problem with "`""`" in pdksh POSIX mode.
5028 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5030 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5031 with pdksh, too. Problem reported by Patrick Welche via
5032 Gary V. Vaughan.
5033 * doc/autoconf.texi (Shellology): Note that set -o posix is
5034 useful for pkdsh, too.
5036 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5038 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5039 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5040 Don't fail if ENV or BASH_ENV is readonly.
5041 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5042 etc. are read only. Problem reported by Ludovic Courtes.
5044 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5046 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5047 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5048 (trivial change)
5050 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5052 * doc/autoconf.texi (File System Conventions): Warn about
5053 names like "aux". Problem reported by Eric Blake.
5055 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5056 by zero instead of array size, so that we can use any arithmetic
5057 constant expression (instead of requiring an integer constant
5058 expression). This allows us to test expressions like DBL_MAX <
5059 LDBL_MAX, which didn't conform to the C standard using the old
5060 method.
5061 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5062 now that we can do floating-point tests at compile time.
5064 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5066 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5067 and LDBL_EPSILON, as the resulting expression isn't an
5068 integer constant expression and violates the C standard.
5069 Problem reported by Nelson H. F. Beebe. Also, check
5070 for "L" suffix, and check that long double doesn't have
5071 worse range or precision than double, that mixed-mode
5072 arithmetic doesn't generate a diagnostic, that double
5073 constants fit in long double.
5075 2004-06-03 Kevin Ryde <user42@zip.com.au>
5077 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5078 malloc(0) and realloc(NULL,size).
5080 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5081 Bob Proulx.
5083 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5085 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5086 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5087 by Jim Meyering.
5089 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5091 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5092 can be rewritten using if-then-else. Suggested by Bruno Haible.
5094 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5096 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5097 Problem reported by Stepan Kasal.
5099 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5101 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5102 change). Patch reported by Ralf Wildenhues in
5103 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5105 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5106 function F exists if the compiler and linker let you compile an
5107 expression like (F != 0). Recent versions of GCC optimize away
5108 the reference to F in that case, since every function address must
5109 be nonzero, so the link succeeds even if F does not exist.
5110 Problem reported by Manu in
5111 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5113 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5114 "Unix". Many uses changed.
5115 (Limitations of Builtins): Explain better why the ! command isn't
5116 portable.
5118 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5120 * lib/autom4te.in (Automake-preselections): Preselect
5121 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5123 2004-05-19 Kevin Ryde <user42@zip.com.au>
5125 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5126 referencing AC_FUNC_STRERROR_R.
5128 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5129 note pessimistic assumption when cross compiling.
5131 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5133 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5134 (until 2004) invoked subcommands with sh -e, contra POSIX.
5135 Reported by Kevin Ryde.
5137 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5139 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5140 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5141 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5142 `test -f " /usr/bin/grep"', which _always_ failed.
5143 (AC_PROG_SED): Ditto bogus PATH fix.
5144 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5145 requires that grep correctly supports _multiple_ `-e' options, rather
5146 than stating only that grep should accept `-e'.
5148 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5150 Port to C99, which requires that 'exit' be declared.
5152 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5153 to ensure that stdlib.h is included.
5154 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5155 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5156 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5157 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5158 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5159 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5160 when using 'exit' in a test; C99 requires that 'exit' be declared.
5162 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5164 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5165 now prefers 'grep' implementations that accept -e.
5166 (Limitations of Usual Tools): Describe problems of traditional
5167 egrep and fgrep with long input lines, and of traditional grep
5168 with -e.
5169 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5170 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5171 All callers changed. Append /usr/xpg4/bin to the PATH, for
5172 Solaris.
5173 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5174 the user with complaints about multiple -e options.
5175 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5176 Define it with AC_PROG_GREP.
5177 * configure.ac (AC_PROG_GREP): Add.
5178 * lib/freeze.mk (GREP): New macro.
5180 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5182 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5183 a possible candidate only after all others fail, rather than
5184 consulting it first. This improves backward compatibility by
5185 better reflecting the way shell selection occurred in previous
5186 versions of Autoconf, and should help to avoid triggering latent
5187 problems in other packages, such as the one in Automake where zsh
5188 is not handled robustly:
5189 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5190 Although it is not Autoconf's responsibility to work around
5191 problems in Automake, it nevertheless makes sense to avoid
5192 introducing unnecessary incompatibilites.
5194 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5195 Gary V. Vaughan <gary@gnu.org>
5197 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5198 how deeply nested we are when a suitable tool is found, set the
5199 ac_path_TOOL_found flag.
5200 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5201 nested we are in this macro. Break out of all 3 nested loops if
5202 ac_path_TOOL_found is set.
5204 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5206 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5207 of the _AS_PATH_WALK loop too if GNU flavor is found.
5209 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5211 * doc/autoconf.texi (Limitations of Make): Update documentation
5212 for `$<'. New entry `Long lines', based on a report from Simon
5213 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5214 paragraph about DJGPP, based on a mail from Richard Dawe.
5216 2004-04-20 Paul Eggert <eggert@twinsun.com>
5218 * tests/c.at (C keywords): Don't assume that GCC supports
5219 "restrict" and "inline", as sufficiently-old GCC versions do not
5220 (also, GCC configured to be in pedantic C89 mode does not).
5221 Problem reported by Sumit Pandya in:
5222 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5224 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5225 consider -g to work if it generates warnings when plain compiles
5226 don't. Problem reported by Braden McDaniel in:
5227 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5229 * doc/autoconf.texi (Slashes): New section, to document a problem
5230 reported by Jim Meyering in:
5231 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5233 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5234 linker output files before linking, to work around IRIX 6 linker bug.
5235 Problem reported by Rainer Orth in:
5236 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5238 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5240 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5241 best tool so far counter rely on the tool path variable name to
5242 avoid checks for one tool being affected by the results of running
5243 the length check on a previous tool.
5245 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5246 match expression argument, as different greps have different
5247 regular expression flavours.
5248 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5249 literals.
5250 (AC_PROG_EGREP): Pass 'EGREP$'.
5251 (AC_PROG_GREP): Pass 'GREP$'.
5253 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
5255 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
5256 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
5258 2004-03-29 Paul Eggert <eggert@twinsun.com>
5260 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
5261 Types, Specific Compiler Characteristics, System Services,
5262 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5263 etc. consistently instead of 'long', 'short', 'unsigned' etc.
5264 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
5265 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
5266 Likewise.
5267 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
5268 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
5269 AC_TYPE_OFF_T): Likewise.
5270 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
5271 Likewise.
5273 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
5274 pacify libtool 1.5.2. Fix quoting problems in sed command.
5276 2004-03-28 Paul Eggert <eggert@twinsun.com>
5278 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
5279 now defines HAVE_DECL_TZNAME if it is declared, when
5280 HAVE_STRUCT_TM_TM_ZONE is not defined.
5281 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5282 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
5283 for HAVE_TZNAME.
5285 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
5287 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
5288 superfluous backslashing of quotes (") in sed expressions;
5289 thanks to Paul Eggert.
5291 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
5293 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
5294 Fortran compiler is ifort, also added pghpf; thanks to Nelson
5295 H. F. Beebe for the bug report.
5297 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
5299 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
5300 quoted -cmdline argument in Portland Group compiler (bug
5301 reported by Jeffrey J. Barteet).
5303 2004-03-25 Kevin Ryde <user42@zip.com.au>
5305 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
5306 (Run Time): ... here, where it's now mentioned.
5308 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
5310 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
5311 inherits from language Autoconf-without-aclocal-m4.
5312 (Customizing autom4te): Adjust example; the cache must now be
5313 disabled for language Autoconf-without-aclocal-m4.
5315 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
5316 Nathanael Nerode <neroden@twcny.rr.com>
5318 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
5319 AC_CHECK_TOOLS): Warn if a cross-tool is found without
5320 a prefix.
5321 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
5322 AC_CHECK_TARGET_TOOLS): New macros.
5323 * doc/autoconf.texi (Generic Programs): Document
5324 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
5325 AC_CHECK_TARGET_TOOLS, and warn for future changes
5326 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
5327 AC_CHECK_TOOLS.
5328 (Specifying Names): Document the reason for these future
5329 behavioral changes.
5330 * tests/mktests.sh: Do not generate tests for the
5331 new macros.
5332 * NEWS: Document these changes.
5334 * doc/autoconf.texi: Avoid macros with unbraced arguments,
5335 they make TeX hang up.
5337 2004-03-15 Paul Eggert <eggert@bogus.example.com>
5339 * NEWS: New macro AC_CHECK_ALIGNOF.
5340 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5341 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
5342 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
5343 vowel.
5344 (AC_CHECK_ALIGNOF): New macro.
5345 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
5346 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
5347 those for sizeof.
5349 2004-03-03 Paul Eggert <eggert@twinsun.com>
5351 * bin/Makefile.am (edit): Don't use $< in a context where
5352 POSIX doesn't require support for it. Use $@.in instead.
5353 Problem reported by Anthony N. Frasso in
5354 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
5355 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
5357 2004-02-23 Gary V. Vaughan <gary@gnu.org>
5359 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
5360 from the next generation of Libtool.
5361 * lib/autom4te.in (Autoreconf-preselections): Ditto.
5363 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5365 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
5366 is not always thread-safe. Report from Nathanael Nerode.
5368 2004-02-18 Paul Eggert <eggert@twinsun.com>
5370 Fix a dependencies problem, stemming from a Autoconf 2.59 build
5371 problem on QNX reported by Stephen Rasku in
5372 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
5374 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
5375 $(m4sh_m4f_dependencies); this removes a FIXME.
5376 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
5377 (MAINTAINERCLEANFILES): Split into pieces,
5378 one per related section. Add $(srcdir)/wrapper.in.
5380 2004-02-09 Paul Eggert <eggert@twinsun.com>
5382 * doc/autoconf.texi (Setting Output Variables): Emphasize that
5383 AC_SUBST provides no portable way to escape literal newlines.
5385 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5386 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5387 Darwin uses -lcrt2.o and there's little point to cataloging all
5388 the system variants. Partial fix reported by Andreas Waechter in:
5389 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
5390 for bug reported by Nelson H. F. Beebe in:

5393 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
5395 * doc/autoconf.texi (AU_DEFUN): Fix English,
5396 suggested by Paul Eggert.
5397 * lib/autoconf/autoupdate.m4: Correct reference to
5398 acobsolete.m4, suggested by Alexandre Duret-Lutz.
5400 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
5402 * bin/autoupdate.in: Define __file__ so that warnings
5403 refer to the correct file.
5404 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
5405 the behavior of the third argument.
5406 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
5407 correctly the behavior of the third argument. Document
5408 what the three macros that AU_DEFUN defines do. Fix
5409 warning message when the third argument includes $0
5410 (reported by Alexandre Duret-Lutz).
5412 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5413 Eric Sunshine <sunshine@sunshineco.com>
5414 Paul Eggert <eggert@twinsun.com>
5416 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
5417 (AS_INIT): Output shell initialization there. Removed optional
5418 parameter. Expand _AS_SHELL_FN_SPY.
5419 (AS_INIT_WITH_SHELL_FN): Removed.
5420 (_AS_SHELL_FN_SPY): New macro.
5421 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
5422 macros.
5423 (AS_SHELL_SANITIZE): Remove loop to find better shell
5424 and documentation for the parameter.
5425 (_AS_DETECT_BETTER_SHELL): Move it here.

5427 (_AS_RUN): Move it here, support testing with eval.
5428 (AS_REQUIRE_SHELL_FN): Require shell functions when
5429 it is used.
5430 (_AS_LINENO_WORKS): Put around braces, we do not
5431 trigger the bash bug anymore.
5432 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
5433 use AS_INIT_WITH_SHELL_FN.
5434 * bin/autoconf.in, tests/wrapper.in: Regenerated.

5442 (AU_DEFUN): Honor the third parameter, create autoupdate
5443 macros with AU_DEFINE.
5444 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
5445 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

5453 * lib/autoconf/status.m4: Remove FIXME.

5464 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
5465 2003 (except 1997) to the list of copyright years. This undoes
5466 the 2003-05-22 change, which removed the older years from the list.
5467 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
5469 2004-01-27 Gary V. Vaughan <gary@gnu.org>

5474 possible.
5475 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
5476 AC_PROG_GREP.
5477 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
5478 egrep and fgrep respectively if $GREP -E/-F don't work.
5479 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
5480 _AC_PROG_GREP, and AC_PROG_SED.
5481 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
5482 longest input length accepted by a command.
5483 (AC_PROG_SED): Use it.
5484 * doc/autoconf.texi (Particular Programs): Document the changes.
5485 * NEWS: Updated.
5487 2004-01-27 Paul Eggert <eggert@twinsun.com>
5489 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

5491 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
5492 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
5494 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
5495 bin/autoconf.in, config/Makefile.in, config/config.guess,
5496 config/config.sub, config/install-sh, config/mdate-sh,

5511 2004-01-26 Paul Eggert <eggert@twinsun.com>
5513 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
5514 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
5515 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
5516 not <inttypes.h>. Problem reported by Tim Mooney in
5517 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
5518 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
5519 Likewise.
5521 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
5522 otherwise "make check" fails because it forbids cmp (I guess
5523 because cmp treats files as binary on DOS-like systems).
5525 * tests/mktests.sh: Update copyright date to 2004, since some tests
5526 have changed in 2004.
5528 2004-01-23 Gary V. Vaughan <gary@gnu.org>

5531 non-truncating sed or gsed program in PATH.
5532 * tests/acprograms.at: Add it.
5533 * doc/autoconf.texi (Particular Programs): Document it.
5534 * NEWS: Updated.
5536 2004-01-15 Paul Eggert <eggert@twinsun.com>
5538 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
5539 -std1 disables some useful extensions on Tru64. Problem reported
5540 by N. Lichtmaier in
5541 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
5543 2004-01-14 Paul Eggert <eggert@twinsun.com>
5545 * doc/autoconf.texi (Programming in M4sh): Document that
5546 AS_MKDIR_P succeeds if the destination is a symbolic link
5547 to an existing directory.
5548 (Limitations of Usual Tools): Note that mkdir -p might not
5549 succeed on symlinks to directories.
5551 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
5553 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
5554 * bin/autoheader.in: Grammar fix in message.
5555 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
5556 Test for dir before calling mkdir -p. (trivial changes)
5558 2004-01-13 Eric Blake <ebb9@byu.net>
5560 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
5561 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
5563 2004-01-10 Jim Meyering <jim@meyering.net>
5565 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
5567 2004-01-09 Paul Eggert <eggert@twinsun.com>
5569 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
5570 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
5571 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
5572 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
5573 AC_COMPILE_IFELSE, since we now assume our caller invokes
5574 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
5575 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
5576 of AC_RUN_IFELSE; this avoids the warning mentioned above.
5577 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
5579 2004-01-07 Paul Eggert <eggert@twinsun.com>
5581 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
5582 `"'...'"`, as it's confusing (and I suspect it may not work on
5583 some platforms). The code was incorrect anyway, as it assumed
5584 that \$ evaluated to itself in that context. Reported by
5585 Alexandre Duret-Lutz.
5587 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
5589 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
5590 and _LT_AC_TAGCONFIG.

5594 * doc/autoconf.texi (One Macro Call): Fix an incorrect
5595 example, and add more examples. Reported by Eric Sunshine.
5597 2004-01-05 Paul Eggert <eggert@twinsun.com>
5599 * doc/autoconf.texi (Limitations of Usual Tools):
5600 Remove warning against "rm -fr" introduced yesterday; it
5601 was a false alarm.
5603 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
5604 autoscan, autoupdate, ifnames): Don't use chmod -w.
5605 * lib/Makefile.am (autom4te.cfg): Likewise.
5606 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
5607 "chmod -w".
5609 2004-01-04 Paul Eggert <eggert@twinsun.com>
5610 Paolo Bonzini <bonzini@gnu.org>
5612 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
5613 by doing lineno substitution only on lines containing "$LINENO".
5615 2004-01-04 Paul Eggert <eggert@twinsun.com>
5617 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
5618 Use "rm -f" to remove conftest.sed, not plain "rm".
5619 Bug reported by David Relson in
5620 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
5622 * Makefile.am (autom4te-update):
5623 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
5624 * Makefile.maint (my-distcheck, do-po-update): Likewise.
5625 * doc/autoconf.texi (Guidelines): Likewise.
5626 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

5631 * tests/Makefile.am (clean-local): Likewise.
5632 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
5633 srcdir): Likewise.
5634 * doc/autoconf.texi (Limitations of Usual Tools):
5635 Warn against "rm -fr".
5637 2004-01-03 Paul Eggert <eggert@twinsun.com>
5639 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
5640 -c -o might not work. From a suggestion by Kevin Ryde.
5641 (C Compiler, Generating Sources, Limitations
5642 of Usual Tools, Limitations of Make, Making testsuite Scripts):
5643 Don't put '-o' after non-options, as POSIX doesn't allow this.
5644 Mention that cc's name might be gcc or c89 or whatever.
5646 2004-01-04 Kevin Ryde <user42@zip.com.au>
5648 * doc/autoconf.texi: Add various further index entries.
5650 2003-12-29 Paul Eggert <eggert@twinsun.com>
5652 * bin/autoreconf.in (autoreconf_current_directory):
5653 Fix typo: mkdir without umask arg.
5655 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
5657 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
5658 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
5659 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
5660 explanation clearer.
5662 2003-12-24 Andreas Schwab <schwab@suse.de>
5664 * doc/autoconf.texi (Default Includes): Fix misspelling of
5665 AC_INCLUDES_DEFAULT.

5669 * configure.ac: Test if sh -n works.
5670 * configure: Regenerate.
5671 * tests/atlocal.in: Store the result here.
5672 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
5673 tools.at, looking in atlocal's ac_cv_sh_n_works instead
5674 of explicitly testing.
5675 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
5676 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
5677 * tests/tools.at (Syntax of the shell scripts): Simplify
5678 using AT_CHECK_SHELL_SYNTAX.

5691 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
5692 Extracted from AS_SHELL_SANITIZE.
5693 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
5694 macros.
5695 (AS_SHELL_SANITIZE): Move reinvocation code from
5696 _AS_LINENO_WORKS, use it to find out if shell
5697 functions work.
5698 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
5699 does not work.
5700 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
5701 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

5715 them on the fly.
5717 2003-11-24 Akim Demaille <akim@epita.fr>
5719 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

5758 patch 3 reported by Eric Sunshine.
5760 2003-11-15 Kevin Ryde <user42@zip.com.au>
5762 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
5763 than $target since the latter is not usual, add guidelines on when to
5764 use or not use the system type.
5766 2003-11-12 Derek Price <derek@ximbiot.com>
5768 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

5842 than `\n\n', so that `\n\n\n' is valid in warnings.
5843 Reported by Steve Huston.
5845 2003-10-28 Akim Demaille <akim@epita.fr>
5847 * Makefile.cfg (local_updates, executable-update): Tweak to be

5876 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_COMPILE_IFELSE):

5889 Use 'eval', so that the resulting configure scripts work even if
5890 the current directory has a weird file name like 'y%s+%pp%;s%@%_%g'.

5923 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
5924 cross test.
5926 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>

5939 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
5940 Issue a more-informative diagnostic.
5941 Problems reported by Eric Sunshine.
5943 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5945 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
5946 -mGLOB_options_string stuff for Intel ifc, which can cause
5947 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
5948 pattern-matching instead of grep.
5950 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5952 * doc/autoconf.texi: Document new FC Fortran macros.
5954 2003-10-08 Gary V. Vaughan <gary@gnu.org>
5956 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
5957 that future autopoint/aclocal/automake/autoreconf will be able
5958 to trace to find where to install local m4 macros.
5959 * doc/autoconf.texi (Input): Document it.
5960 * NEWS: Updated.

5966 -lcrt[01].o.
5968 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
5970 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5971 cache variable instead of $G77 to decide whether to include -O2,
5972 since $G77 is specific to Fortran 77.
5974 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5976 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
5977 free" flag. Re-order flags tested into rough order of popularity.
5979 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5981 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
5982 arguments so that it can be used with syntax identical to
5983 AC_PROG_F77, and so that we can more easily decide to
5984 remove/deprecate the DIALECT optional argument in the future if it
5985 proves troublesome.
5986 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
5987 non-freeform-supporting compilers. Document freeform flags.
5989 2003-10-03 Akim Demaille <akim@epita.fr>
5991 * configure.ac: Look for emacs, not macs.
5992 Reported by Eric Sunshine.
5994 2003-10-03 Akim Demaille <akim@epita.fr>
5996 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
5997 * bin/autoreconf.in (autoreconf_current_directory): Create the
5998 AUX_DIR if needed, for sake of automake --add-missing etc.
5999 Suggested by Alexandre Duret-Lutz.
6001 2003-10-03 Akim Demaille <akim@epita.fr>
6003 * configure.ac: Quotation and formatting changes.

6050 Problem reported by Lars J. Aas in
6051 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
6052 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6053 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6054 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6056 2003-09-26 Akim Demaille <akim@epita.fr>
6058 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6059 directory for AC_CONFIG_COMMANDS' first argument exists.
6060 This makes valid the invocation of _AC_SRCPATH that follows.
6061 Reported by Eric Sunshine.
6062 * doc/autoconf.texi (Configuration Commands): Adjust.
6064 2003-09-26 Akim Demaille <akim@epita.fr>
6066 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6067 Reported by Ralf Corsepius.
6069 2003-09-26 Akim Demaille <akim@epita.fr>
6071 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6072 arguments.
6073 Actually, use AU_ALIAS.
6074 From Bruno Haible.
6076 2003-09-26 Paul Eggert <eggert@twinsun.com>
6078 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
6079 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
6080 Problem reported by Eric Sunshine in:

6083 2003-09-26 Akim Demaille <akim@epita.fr>
6085 The test suite are sometimes assigning timings incorrectly.
6086 Reported by Henk Krus.
6087 Diagnosed by Nicolas Joly.
6089 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6090 AT_help_all.
6091 Instead of making AT_help a sequence of assignments to grow
6092 $at_help_all, just make AT_help_all be the growing contents of
6093 $at_help_all, and make a single assignment in...
6094 (AT_INIT): here.
6095 (at_times_skip): Flip the meaning and rename as...
6096 (at_times_p): this.
6097 (AT_INIT): When summarizing the test that ran, remove
6098 $at_times_file after use, and check it is present before trying to
6099 use it.
6101 2003-09-25 Akim Demaille <akim@epita.fr>
6103 Version 2.57d.
6105 * bin/Makefile.am (edit): Handle '@configure_input@'.
6106 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6107 (ifnames): chmod -w.
6108 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6109 executables, not bin/ executables! Otherwise all the magic needed
6110 to find non installed files is turned off. This caused a failure
6111 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6112 as found in its environment (sent by tests/autoreconf): pointing
6113 to bin/autom4te that could not find its files.
6114 * tests/mktests.sh: Force the replacement of generated files, for
6115 the sake of "mv" program that are interactive when overwriting a
6116 -w file.
6117 * config/install-sh: Upgrade from CVS Automake.
6119 2003-09-23 Paul Eggert <eggert@twinsun.com>
6121 * doc/autoconf.texi (Limitations of Builtins): Document test -h
6122 versus test -L issues.
6124 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
6125 Paul Eggert <eggert@twinsun.com>
6127 Trivial change to support GCC's configuration procedure.
6128 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6129 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6130 about inconsistency if the preprocessor is set to give errors for
6131 any warning.
6132 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6134 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
6136 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm

6147 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
6148 from masters.
6150 2003-09-12 Akim Demaille <akim@epita.fr>
6152 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
6153 not asm/types.h.
6155 2003-09-11 Akim Demaille <akim@epita.fr>
6157 * doc/autoconf.texi (Header Portability): linux/random.h.
6158 From Peter Hendrickson.
6160 2003-09-10 Akim Demaille <akim@epita.fr>
6162 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6163 willing to edit the output files.
6165 2003-09-10 Akim Demaille <akim@epita.fr>
6167 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6168 and AC_FC_FREEFORM.
6169 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6170 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
6172 2003-09-09 Akim Demaille <akim@epita.fr>

6185 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
6186 Improve the accuracy of the wording about obsolescence.
6187 From a suggestion by Ian Lance Taylor in
6188 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
6190 2003-09-05 Paul Eggert <eggert@twinsun.com>
6192 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6193 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6195 2003-09-04 Akim Demaille <akim@epita.fr>
6197 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6198 AC_FUNC_WAIT3.
6200 2003-09-04 Akim Demaille <akim@epita.fr>
6202 * bin/autom4te.in: Use &fatal where more appropriate than &error.
6203 (freeze): When exiting, use $exit_code.
6204 * lib/autoconf/fortran.m4: Comment changes.
6206 2003-09-04 Akim Demaille <akim@epita.fr>
6208 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
6210 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6212 Add support for newer Fortran dialects. The F77 interface is
6213 unchanged, and continues to support Fortran 77. New FC macros
6214 correspond to all the old F77 macros, with output variables FC,
6215 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6216 available dialect, but older dialects can be specified. There are
6217 new macros AC_FC_SRCEXT to set the source extension, and
6218 AC_FC_FREEFORM to accept free-form source files.
6220 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
6221 New macros.
6222 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
6223 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

6233 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
6234 AC_FC_SRCEXT, AC_FC_FREEFORM):
6235 New macros.
6236 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
6237 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
6238 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
6239 Rewrite in terms of the above.
6240 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
6241 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

6245 2003-09-02 Paul Eggert <eggert@twinsun.com>
6247 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
6248 Document problems with timestamp resolution that 'make', 'cp -p', and
6249 'touch -r' have.
6251 2003-08-27 Akim Demaille <akim@epita.fr>
6253 * tests/m4sugar.at (cross_warning): Make sure to enable the
6254 output, so that we can track spurious m4sugar output.
6255 * tests/local.at: Require 2.57.
6256 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
6257 are defaulted by AT_CHECK anyway.
6258 Use AT_CHECK_AUTOM4TE.
6259 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
6260 missing dnl.
6262 2003-08-27 Akim Demaille <akim@epita.fr>
6264 * bin/autoheader.in: Issue the "Using auxiliary..." message only
6265 when -Wobsolete is set.
6266 Set it on by default.
6267 Suggested by Klee Dienes.
6269 2003-08-27 Akim Demaille <akim@epita.fr>

6316 Replace the former...
6317 (m4_warn): Pass the call stack to _m4_warn.
6318 * bin/autom4te.in: Adjust to output the call stack.
6319 * tests/m4sugar.at (m4@&t@_warn): Adjust.
6321 2003-08-22 Akim Demaille <akim@epita.fr>
6323 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.

6339 &parse_WARNINGS.
6340 ($help): Use Autom4te::ChannelDefs::usage.
6341 * bin/autoscan.in: Use Autom4te::ChannelDefs.
6342 * lib/Autom4te/General.pm: Don't export error: you don't own it.
6344 2003-08-21 Akim Demaille <akim@epita.fr>
6346 First stab at preserving warnings between calls to autom4te,
6347 including when the cache is used.
6349 There are still several issues: (i) there are too many runs of m4
6350 (one for include, one for warnings, and some more), (ii) warnings
6351 spreading on several lines are not handled gracefully, (iii) the
6352 code meant to have the call stack display for errors does not work
6353 (its handling should move from m4 to autom4te).
6355 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6356 Use them.
6357 (@preselect): Add m4_warn.
6358 ($exit_status): Remove, use $exit_code.
6359 ($help): Use Autom4te::ChannelDefs::usage.
6360 (&handle_m4): No longer define the m4_warnings.
6361 At each run, extract and report the warnings.
6362 Always cache the result, including if the exit status is on
6363 failure, since if nothing changes, we should result in the same
6364 failure, hence we can use the cache.
6365 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6366 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6367 Remove.
6368 (m4_warn): Redefine as a do-nothing: it is its invocation that
6369 matters, as warnings are now reported via traces.
6370 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6371 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6372 the latter reveals calls to the former.
6374 Adjust the tests.
6376 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6378 2003-08-21 Akim Demaille <akim@epita.fr>

6410 * bin/autom4te: Adjust.
6411 In particular, be Autoconf tools are really silent when properly
6412 working, bind the verbosity of the 'note' channel to $verbose.
6413 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
6414 (&xsystem, &contents): Remove, since they are exported by...
6415 * lib/Autom4te/FileUtils.pm: this.
6416 More perldoc.
6417 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
6418 * lib/Autom4te/FileUtils.pm: here.
6420 2003-08-20 Akim Demaille <akim@epita.fr>
6422 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
6423 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
6424 from CVS Automake.

6449 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,

6476 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
6477 shorter column three. Add DESCRIPTION to log file content.
6479 2003-08-13 Derek Price <derek@ximbiot.com>
6481 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
6482 output.
6484 2003-08-12 Derek Price <derek@ximbiot.com>
6486 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
6487 (AT_CHECK_NOESCAPE): Move core functionality to...
6488 (_AT_CHECK): ...this new macro.
6490 2003-08-07 Derek Price <derek@ximbiot.com>
6492 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
6493 (AT_CHECK_NOESCAPE): ...to this new macro.
6495 2003-07-31 Paul Eggert <eggert@twinsun.com>
6497 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
6498 in Bash 2.01. Problem reported by Brian Gough in
6499 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
6501 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
6503 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
6504 -lcrt1.o, for OS X. (trivial change)
6506 2003-07-07 Paul Eggert <eggert@twinsun.com>
6508 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
6509 inside '#ifndef __cplusplus'. Problem reported by
6510 Bob Friesenhahn.
6512 2003-07-06 Bill Clarke <llib@computer.org>
6514 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
6515 'long', not 'int', for benefit of Sun's recent C++ compilers
6516 (trivial change). See:
6517 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
6518 (This really should be 'intptr_t', not 'long', but that would
6519 take more work.)
6521 2003-06-25 Akim Demaille <akim@epita.fr>
6523 * lib/Makefile.am (autom4te.cfg): Make it read only.
6524 Depend on Makefile since it contains substitutions.
6525 From Paolo Bonzini.
6526 * lib/autom4te.in (args): Add local.at? for Autotest args.
6527 This change was made on autom4te.cfg which is generated.
6528 Reported by Raja R. Harinath.
6530 2003-06-25 Akim Demaille <akim@epita.fr>
6532 * doc/autoconf.texi (Header Portability): sys/mount.h.
6533 From Gareth McCaughan.
6535 2003-06-23 Akim Demaille <akim@epita.fr>
6537 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
6538 not all of them. This fixes 1. the fact that when testing
6539 Autoconf there are many many config.log, 2. the incorrect use of
6540 top_srcdir to find config.log.
6541 Don't mix the detailed output of failed test with the summary of
6542 failures. Rather, append detailed log afterwards.
6544 2003-06-23 Akim Demaille <akim@epita.fr>
6546 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
6547 always run: output config.log on $at_group_log.
6549 2003-06-23 Akim Demaille <akim@epita.fr>
6551 * tests/torture.at (#define header templates): Don't use quotes in
6552 C++ comments as it puzzles Emacs' sh font-lock-mode.
6554 2003-06-23 Akim Demaille <akim@epita.fr>
6556 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
6557 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
6558 * tests/atspecific.m4: Rename as...

6561 * tests/local.at: here.
6562 * tests/Makefile.am: Adjust.
6563 * doc/autoconf.texi (testsuite Scripts): Adjust.
6565 2003-06-21 Kevin Ryde <user42@zip.com.au>
6567 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
6568 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
6569 ensuring we add -std1 for full-ANSI.
6571 * doc/autoconf.texi (hdrindex): New macro.
6572 Add index entries for portability of various standard header files.
6574 2003-06-20 Akim Demaille <akim@epita.fr>
6576 * configure.ac: Bump to 2.57b.
6578 2003-06-20 Akim Demaille <akim@epita.fr>
6580 Version 2.57a.
6582 2003-06-20 Akim Demaille <akim@epita.fr>
6584 * bin/autom4te.in: Don't rely on $HOME being defined.
6585 Reported by Marc Espie as PR/233.
6587 2003-06-20 Akim Demaille <akim@epita.fr>
6589 * lib/autotest/general.m4: Use at_times_file only if used.
6590 From Nicolas Joly.
6592 2003-06-20 Akim Demaille <akim@epita.fr>
6594 * config/config.guess, config/config.sub, config/elisp-comp,
6595 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
6596 Update from masters.
6598 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
6600 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
6601 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
6602 (TEST_SCRIPT): New diversion.
6603 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
6604 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
6605 (AT_INIT): Support for expected failures.
6607 2003-06-02 Akim Demaille <akim@epita.fr>
6609 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
6610 changes.
6611 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
6612 Autoconf nor Automake.
6613 (&contents): New, from Automake.
6614 PODify.
6616 2003-05-28 Paul Eggert <eggert@twinsun.com>
6618 * NEWS, doc/autoconf.texi (Particular Functions),
6619 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
6620 is the inverse of localtime.
6622 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
6624 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
6625 (handle_exec_errors): New function. Work around $! being
6626 altered by WEXITSTATUS.
6627 (xqx, xsystem): Use handle_exec_errors.
6629 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
6631 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
6632 Do not call `_exit()', simply modify `$?'.
6633 (xsystem): Reset $! before running system, and check it afterward.
6634 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
6635 63 for version mismatches.
6637 2003-05-23 Akim Demaille <akim@epita.fr>
6639 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
6640 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
6641 the middle of a line).
6642 * lib/m4sugar/m4sugar.m4: Likewise.
6643 Remove useless spaces in comments.
6645 2003-05-23 Akim Demaille <akim@epita.fr>
6647 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
6648 exit 63, so that we (or Automake's "missing") can tell the
6649 difference with a plain failure.
6650 * doc/autoconf.texi (Notices): Adjust.
6652 2003-05-23 Akim Demaille <akim@epita.fr>
6654 * Makefile.am, bin/Makefile.am, config/Makefile.am,
6655 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
6656 White spaces cleanup.
6658 2003-05-22 Jim Meyering <jim@meyering.net>
6659 Paul Eggert <eggert@twinsun.com>
6661 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6662 Remove `#include <stdlib.h>' from the list; we should never
6663 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6664 resulting namespace pollution would cause other tests to fail.
6665 Configure scripts run with some older versions of g++ and HP's
6666 aCC would fail due to such an #include. Problems reported by
6667 Matthew Mueller in <http://bugs.debian.org/120704> and by
6668 Keith Bostic in
6669 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6670 In the test, use the test declaration before including <stdlib.h>,
6671 as that's closer to how it'll be used.
6673 2003-05-23 Akim Demaille <akim@epita.fr>
6675 * doc/autoconf.texi (Header Portability): ucred.h.
6676 From Ian Redfern.
6678 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6680 Overhaul Autotest's logging: generate separate log files
6681 in testsuite.dir/NNN/testsuite.log, and append them to
6682 testsuite.log instead of re-running the test verbosely.
6684 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6685 file descriptor, write 0 to at_status_file instead of setting
6686 at_status=0, initialize some new variables (at_status_file,
6687 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6688 to rerun the tests, instead append the at_group_log to the
6689 at_suite_log when a test fails.
6690 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6691 with the AS_MESSAGE_LOG_FD redirected to stdout.
6692 (AT_CLEANUP): save the output status in $at_status_file
6693 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6694 its original place.
6695 (AT_CHECK): since tests are run with a redirected stdout,
6696 and used to be re-run in verbose mode, turn some $at_verbose
6697 into echo, and don't redirect the output of testing stdout
6698 and stderr.
6700 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6701 the name of the debugging directory and information about
6702 its contents.
6704 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6706 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
6707 parameter.
6709 2003-05-22 Akim Demaille <akim@epita.fr>
6711 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
6712 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
6713 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

6730 Suggested by Jim Meyering.
6732 2003-05-22 Akim Demaille <akim@epita.fr>
6734 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
6735 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
6736 Reported by Jim Meyering.
6738 2003-05-22 Akim Demaille <akim@epita.fr>
6740 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.
6741 Add AC_HELP_STRING to the obsolete macros section.
6742 Typos.
6743 Use '@.' for sentences that ended in a capital letter.
6744 From Art Haas.

6773 2003-05-17 Akim Demaille <akim@epita.fr>
6775 * lib/autoconf/functions.m4: Use the default includes so that
6776 memcmp be declared before being tested.
6777 Reported by Sander Niemeijer.
6778 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
6779 * doc/autoconf.texi (Default Includes): Document
6780 AC_INCLUDES_DEFAULT.
6782 2003-05-17 Akim Demaille <akim@epita.fr>
6784 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
6785 * doc/autoconf.texi (Obsolete Macros): Adjust.
6786 Reported by Werner LEMBERG and Debian Bug 190886.
6788 2003-05-16 Akim Demaille <akim@epita.fr>
6790 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
6791 user name space clashes.
6792 Reported by Bruno Haible.
6794 2003-05-16 Akim Demaille <akim@epita.fr>
6796 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
6797 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
6798 them uniform, and more robust to Perl special characters.
6799 Reported by Martin Mokrejs.
6801 2003-05-14 Akim Demaille <akim@epita.fr>

6819 and truncate.
6821 2003-05-06 Akim Demaille <akim@epita.fr>
6823 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6824 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6825 by aclocal.m4 is changed it might require the importing of another
6826 m4 extension file, i.e., aclocal must be run.
6828 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6829 (&parse_args): Use --force with aclocal if required and supported.

6834 Lock autom4te's cache.
6836 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
6837 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6838 argument instead of a file name, so that the request file remains
6839 open during the whole autom4te run.
6840 ($icache_file): New.
6841 (&freeze): Lock the $icache_file.
6843 2003-04-29 Derek Price <derek@ximbiot.com>
6845 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6846 seperator with m4_append_uniq(). It doesn't work.
6847 (AT_CLEANUP): Add `;' to end of at_help_all.
6848 (AT_INIT): Allow --keywords to be specified more than once. When
6849 grepping $at_help_all for keywords, use the field and keyword
6850 seperators to ensure a complete keyword match. Alter at_prev handling
6851 to support the new --keywords behavior.
6853 2003-04-27 Karl Berry <karl@freefriends.org>
6855 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6856 align better with others. I also made some of the individual
6857 entries on one line, for brevity and to make it easier for me to

6938 2003-03-27 Derek Price <derek@ximbiot.com>
6940 * lib/autotest/general.m4: Eliminate main loop and reorganize test
6941 layout in order to allow scripting around test groups.

6956 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
6957 * tests/m4sh.at (AS_HELP_STRING): New test.
6959 * tests/acgeneral.at: Regenerated.
6961 2003-03-26 Derek Price <derek@ximbiot.com>
6963 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
6964 sense. Verbosify the diversion definitions comment.

7003 Tru64 make in the "target lookup" section.
7004 (Automake): Automake 1.5+ no longer requires special tools to be
7005 present on the developer's host.

7013 * bin/autom4te.in (BEGIN): Likewise.
7014 * bin/autoreconf.in (BEGIN): Likewise.
7015 * bin/autoscan.in (BEGIN): Likewise.
7016 * bin/autoupdate.in (BEGIN): Likewise.

7021 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
7022 to cope with DOS-style absolute paths, when constructing
7023 ${ac_make}.
7025 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
7026 When constructing paths with IFS=:, quote the path. If we're
7027 constructing a DOS-style absolute path, we don't want to split it
7028 on the colon.
7030 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
7031 in description.
7033 2003-02-25 Pavel Roskin <proski@gnu.org>

7045 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
7046 to fix a mismatch between example and discussion.

7050 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
7051 format starting with "-".
7053 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7055 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
7056 is not portable inside Makefile.
7058 2003-02-20 Akim Demaille <akim@epita.fr>
7060 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7061 compiler says yeah, but preproc says nope, compiler is right.
7062 Conversely, prompt the reader to send a bug report to the
7063 maintainers of the package, not of Autoconf.
7065 2003-02-20 Klee Dienes <kdienes@apple.com>
7067 * bin/autoreconf.in (autoreconf_current_directory): Properly

7074 From Larry Jones.
7076 2002-12-23 Paul Eggert <eggert@twinsun.com>
7078 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7079 innocuous variant befor including <limits.h> or <assert.h>. This
7080 works around a bug reported by Albert Chin: HP-UX 11i
7081 (and earlier versions) have a <limits.h> that declares
7082 gettimeofday and many other functions.
7084 2002-12-03 Paul Eggert <eggert@twinsun.com>
7086 Version 2.57.
7088 * NEWS, configure.ac: Update version.
7090 * doc/fdl.texi: Upgrade to FDL version 1.2.
7092 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7093 nontrivially in main's body, so that f's external declaration is
7094 not optimized away in AIX. This should fix the bug reported by
7095 Martin Frydl in
7096 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7098 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7099 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7100 defined, to support freestanding compilers. This should fix the
7101 bug reported by Momchil Velkov in
7102 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7104 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7105 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

7110 * Makefile.maint (www-gnu): New macro.
7111 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
7112 the location has moved.
7114 2002-12-02 Martin Frydl <martin@systinet.com>
7116 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
7117 \(.*\) match is too long and there is something more to be checked.
7118 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
7120 2002-11-15 Akim Demaille <akim@epita.fr>

7126 * config/move-if-change: Indenting changes.
7127 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
7128 * configure.ac (AM_INIT_AUTOMAKE): here.
7129 Require 1.7.1.
7131 2002-11-14 Akim Demaille <akim@epita.fr>
7133 Version 2.55.
7135 * config/config.guess, config/config.sub, config/install-sh:
7136 Update from masters.
7138 2002-11-14 Akim Demaille <akim@epita.fr>
7140 * Makefile.maint: Sync with Bison, i.e.:
7141 (po-check): Scan .l and .y files instead of the
7142 .c and the .h files that they generate. This fixes the bug
7143 reported by Tim Van Holder in:
7144 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7145 Look for N_ as well as for _. Try to avoid matching #define for
7146 N_ and _.
7147 From Paul Eggert.
7149 2002-11-14 Akim Demaille <akim@epita.fr>
7151 * doc/autoconf.texi (C Compiler): Compiling several files at once.
7152 From Paul Eggert and Albert Chin-A-Young.
7154 2002-11-14 Akim Demaille <akim@epita.fr>
7156 * doc/autoconf.texi (C Compiler): Solitary backslashes.
7157 From Paul Eggert and Albert Chin-A-Young.
7159 2002-11-14 Kevin Ryde <user42@zip.com.au>
7161 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
7162 than assigning in main, to avoid HP cc +O3 optimizing it away.
7164 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
7166 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
7167 option. Process --recheck after parsing all options. Pass -q
7168 option to configure on --recheck.
7169 (AC_OUTPUT): Pass -q from configure to config.status.
7170 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
7171 arguments to record.
7172 * doc/autoconf.texi (config.status Invocation): Document
7173 config.status -q option.
7175 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
7177 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
7178 Makefile.in if Makefile.am exists.
7179 (output): Strip `.am' from Makefiles. Don't
7180 output AC_CONFIG_FILES if no Makefiles were found.
7182 2002-11-07 Akim Demaille <akim@epita.fr>
7184 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
7185 (local_updates): New.

7189 2002-11-06 Akim Demaille <akim@epita.fr>
7191 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
7192 declaration in extern "C" too.

7195 2002-11-06 Akim Demaille <akim@epita.fr>
7197 * tests/torture.at (Configuring subdirectories): Don't use grep
7198 -w.
7199 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
7200 Reported by Ezra Peisach.
7202 2002-11-05 Akim Demaille <akim@epita.fr>
7204 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7205 Remove.
7206 We _have_ to stop using the old compatibility scheme that tried to
7207 avoid useless backslashes because Libtool 1.4.3 contains a
7208 AC_DEFINE([error_t], [int],
7209 [Define to a type to use for \`error_t' if it is not
7210 otherwise available.])
7211 We _have_ to quote the single quote and backslashes with \. The
7212 old compatibility scheme saw that ` was backslashed, and therefore
7213 did not quote the single quote. Hence before this patch, Autoconf
7214 was not compatible with Libtool.
7216 2002-11-04 Paul Eggert <eggert@twinsun.com>
7218 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

7223 2002-11-04 Akim Demaille <akim@epita.fr>
7225 Version 2.54c.
7227 * Makefile.maint (update, cvs-update, po-update, do-po-update):
7228 New.
7229 * config/texinfo.tex: Update.
7231 2002-11-03 Akim Demaille <akim@epita.fr>
7233 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
7234 from...
7235 (&autoreconf): here.
7236 ($help, $make, &parse_args, &autoreconf_current_directory):
7237 Support -m/--make.
7238 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7240 2002-10-31 Bruno Haible <bruno@clisp.org>

7253 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
7254 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
7256 2002-10-31 Akim Demaille <akim@epita.fr>
7258 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
7259 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
7260 Make variable, not a shell variable.
7261 Suggested by Bruno Haible.
7263 2002-10-31 Akim Demaille <akim@epita.fr>
7265 * bin/autom4te.in (load_configuration): Reject #args out of any
7266 language.
7268 2002-10-31 Akim Demaille <akim@epita.fr>
7270 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
7271 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
7272 (_AC_RUN_IFELSE): Use it.
7273 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
7274 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
7275 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
7276 inline it.

7282 Suggested by Tim van Holder.
7284 2002-10-29 Paul Eggert <eggert@twinsun.com>
7286 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
7287 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
7288 Problem reported by Bruno Haible.
7290 2002-10-29 Akim Demaille <akim@epita.fr>
7292 * doc/autoconf.texi (Header Templates): Put also in words what the
7293 pictures says to assist free style readers.
7294 (Customizing autom4te): s/--cache=/--cache /.
7296 2002-10-29 Akim Demaille <akim@epita.fr>
7298 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
7299 sys/wait.h.
7300 sparc_address_test returns void.
7301 Use it with an argument, as prototyped.
7302 From Bruno Haible.
7304 2002-10-29 Akim Demaille <akim@epita.fr>
7306 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

7312 * tests/torture.at (Deep Package): New test.

7318 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
7319 * doc/autoconf.texi (Invoking autom4te): Rename as...
7320 (autom4te Invocation): this, for consistency with the other nodes.
7322 2002-10-29 Akim Demaille <akim@epita.fr>
7324 * lib/autom4te.in (Autoconf): s/automate/autom4te/.
7325 Reported by Ralf Corsepius.
7327 2002-10-29 Akim Demaille <akim@epita.fr>
7329 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
7330 characters is a back as an `obsolete' warning now.
7331 Reported by Ralf Corsepius.
7333 2002-10-28 Akim Demaille <akim@epita.fr>
7335 * configure.ac: Bump to 2.54c.
7337 2002-10-28 Akim Demaille <akim@epita.fr>
7339 Version 2.54b.

7546 2002-10-22 Akim Demaille <akim@epita.fr>
7548 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

7552 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
7553 strings.
7555 2002-10-22 Akim Demaille <akim@epita.fr>
7557 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

7604 longer required can still cause errors.
7605 Reported by Alexandre Duret-Lutz.
7607 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
7608 to frozen files in @ARGV, as @ARGV must remain being a list of
7609 files. Rather, at M4 call sites, use this...
7610 (&files_to_options): New function.
7611 (&freeze): Use &error.
7612 (&up_to_date): If a file that was included according to the cache
7613 is no longer there, then the output is out dated.
7614 (&main): Don't even check whether a file is up to date is anyway
7615 --force is given.
7616 * tests/tools.at (autom4te cache): New.
7618 2002-10-16 Akim Demaille <akim@epita.fr>

7623 Factor some code.
7624 (&autoreconf): Report the directories we enter *and leave*, so
7625 that error messages can be easily located, and use GNU Make
7626 format, so that Emacs' compile mode understands us.
7627 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
7628 if some file was changed instead of `print'.
7629 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

7663 file name to enable parallel executions.
7664 From Sam Varshavchik.
7666 2002-10-08 Akim Demaille <akim@epita.fr>
7668 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7669 aclocal invocation, as Gettext macros might not be visible to
7670 aclocal.
7671 Instead of blindly running autopoint, scan configure.ac (not the
7672 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
7673 Reported by Paul D. Smith.
7675 2002-10-08 Paul Eggert <eggert@twinsun.com>
7677 Work around problems found when POSIXLY_CORRECT=1 is set.
7678 None of this seems to have anything to do with POSIX, really,
7679 but it's how Perl getopt works.
7680 * bin/autom4te.in (parse_args): Configure GetOpt with
7681 "permute", too.
7682 * doc/autoconf.texi (Invoking autom4te):

7705 * tests/torture.at (Configuring subdirectories): Be robust to
7706 users who use config.site to require for a cache: in this case,
7707 the two last configure runs, using two different sets of
7708 arguments, trigger a legitimate error.
7710 2002-09-28 Akim Demaille <akim@epita.fr>

7726 (tm_zone): Move their rules to...
7727 * lib/autoconf/types.m4: here, using AN_ macros.
7728 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
7729 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7730 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
7731 * lib/autoconf/programs.m4: here.

7745 tests/autom4te itself.
7746 * lib/autoscan/Makefile.am: Include freeze.mk.
7747 (autoscan.list): New target --this file is no longer a source.
7748 (autoscan.pre): New file.

7752 * bin/autoscan.in (@kinds): Make them singular.
7753 Adjust all uses.
7754 (&init_tables): When --debug, report the list of rules to ease
7755 tracking changes in autoscan.list.
7756 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7758 2002-09-28 Akim Demaille <akim@epita.fr>

7771 `functions' line is now prefixed with `function:'.
7772 * bin/autoscan.in (&init_tables): Adjust.
7774 2002-09-28 Akim Demaille <akim@epita.fr>
7776 From now on, autoscan files must always map a macro name to a
7777 word: there is no `default' macro for autoscan.
7779 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7780 all.
7781 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7782 explicit.
7784 2002-09-28 Akim Demaille <akim@epita.fr>
7786 * bin/autoscan.in (%c_keywords): Remove.

7819 Reported by Ralf Corsepius.
7820 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7822 2002-09-26 Akim Demaille <akim@epita.fr>
7824 Single suffix rules and seperated dependencies are not portable.
7826 * doc/autoconf.texi (Installation Directory Variables): Update.

7829 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7830 (ifnames, autoscan, autom4te): Un-factor into several rules.
7832 2002-09-25 Paul Eggert <eggert@twinsun.com>
7834 * BUGS (Interoperability bugs): New section. Mention libtool
7835 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
7837 2002-09-24 Paul Eggert <eggert@twinsun.com>
7839 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
7840 make handles suffix-rules differently from GNU make.
7842 * bin/Makefile.am (SUFFIXES, .in): Remove.
7843 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
7844 Move the body of the old .in rule here.
7846 2002-09-16 Akim Demaille <akim@epita.fr>
7848 i960 compilers create `b.out' files by default.
7849 Reported by Ralf Corsepius.
7851 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
7852 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
7854 2002-09-13 Paul Eggert <eggert@twinsun.com>
7856 * doc/autoconf.texi (Particular Headers): Remove obsolete
7857 reference to `struct timezone' in the description of
7858 AC_HEADER_TIME.
7860 2002-09-13 Akim Demaille <akim@epita.fr>
7862 Version 2.54.
7864 * config/config.sub, config/config.guess: Update.
7865 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
7866 * Makefile.am: Adjust.
7868 2002-09-13 Akim Demaille <akim@epita.fr>
7870 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
7871 reading config.log when the compiler is rejected.
7872 Suggested by Guido Draheim.
7874 2002-09-13 Akim Demaille <akim@epita.fr>
7876 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
7877 (chdir_init) might hang when stat'ing mounted directories.
7878 Reported by Vance Shipley.
7880 2002-09-12 Akim Demaille <akim@epita.fr>
7882 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7883 the lists.
7885 2002-09-12 Akim Demaille <akim@epita.fr>
7887 * doc/autoconf.texi (Defining Symbols): Present two different
7888 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
7889 difference between 1 argument calls, and 2-3 argument calls.
7891 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
7893 * doc/autoconf.texi: Review grammar and punctuation.
7895 2002-09-11 Paul Eggert <eggert@twinsun.com>
7897 * doc/autoconf.texi: Fix minor formatting, spelling, and
7898 grammatical typos.
7899 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7900 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7901 is obsolescent.
7903 2002-09-11 Akim Demaille <akim@epita.fr>
7905 * doc/autoconf.texi (Questions): Rename as...
7906 (FAQ): this.
7907 (Defining Directories): New.
7909 2002-09-09 Akim Demaille <akim@epita.fr>
7911 * doc/autoconf.texi (Making testsuite Scripts): Update.
7912 Suggested by Nishio Futoshi.
7914 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
7916 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
7917 plain `@' is wanted.
7919 2002-09-09 Akim Demaille <akim@epita.fr>
7921 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7922 `duplicates', since the algorithm was too naive and could keep
7923 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7924 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7925 Reported by Ralf Corsepius.
7926 * tests/torture.at (Configuring subdirectories): Exercise these
7927 cases.
7929 2002-09-09 Akim Demaille <akim@epita.fr>
7931 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
7932 looking for a replacement file.
7933 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7934 directory is relative.
7935 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7936 directory definition.
7937 Reported by Andreas Schwab and Jim Meyering.
7939 2002-09-06 Akim Demaille <akim@epita.fr>
7941 * doc/autoconf.texi (Setting Output Variables): Clarify what
7942 precious variables are.
7943 Suggested by Pontus Skoeld.
7945 2002-09-05 Akim Demaille <akim@epita.fr>
7947 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7948 (ifnames, autoscan, autom4te): Since we don't only depend on
7949 configure.ac variables (such as VERSION etc.), but also on prefix
7950 and so forth, depend on Makefile, not configure.ac.
7951 Reported by Alexandre Duret-Lutz.
7952 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7954 2002-09-05 Kevin Ryde <user42@zip.com.au>
7956 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7957 doesn't seem to be confined to ia64, just say "some versions".
7959 2002-09-04 Akim Demaille <akim@epita.fr>
7961 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
7962 Automake 1.6c.
7963 * Makefile.am (maintainer-clean-local): Remove.
7964 (MAINTAINERCLEANFILES): Remove COPYING.
7966 2002-09-03 Paul Eggert <eggert@twinsun.com>
7968 * doc/autoconf.texi (Configuration Commands): Remove obsolete
7969 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
7970 Brinkmann.
7972 2002-09-03 Akim Demaille <akim@epita.fr>
7974 * configure.ac: Bump to 2.53d.
7975 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
7976 as of today, on Automake's team suggestion.
7978 2002-09-03 Akim Demaille <akim@epita.fr>
7980 Version 2.53c.
7982 2002-09-02 Akim Demaille <akim@epita.fr>
7984 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7985 SITE_MACRO_DIR.
7986 * configure.ac: Disable SITE_MACRO_DIR.
7988 2002-09-02 Jim Meyering <meyering@lucent.com>
7990 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7991 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7992 Also, tweak grammar: s/make sure to/be sure to/.
7994 2002-09-02 Paul Eggert <eggert@twinsun.com>
7996 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7997 directory names are generally preferable to physical names.
7999 2002-09-02 Akim Demaille <akim@epita.fr>
8001 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8002 Reported by Raja R. Harinath.
8003 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8004 * bin/autoupdate.in: Use error instead of die.
8006 2002-09-01 Paul Eggert <eggert@twinsun.com>
8008 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8009 ordinary shell concatenation rather than echo+tr+sed command that
8010 runs afoul of a long-line-related sed bug in Solaris 8.
8012 * bin/autoheader.in (parse_args): --warning -> --warnings.
8014 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8015 stdout, as traditional "ls" does.
8016 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8017 _AC_COMPILER_EXEEXT_O): Likewise.
8018 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8020 * bin/autoconf.as: Add --prepend-include option. This patch was
8021 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8022 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8024 * bin/autoconf.in, configure: Regenerate.
8026 * doc/autoconf.texi (Special Shell Variables): Mention
8027 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8029 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8030 MAILPATH and set PS1, PS2, PS4 to default values, to work
8031 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8032 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8033 the Autoconf documentation specifies; fall back to "unset" only if
8034 this fails. Use a shell for-loop for this rather than an m4 loop,
8035 to shorten the output script.
8037 2002-08-30 Paul Eggert <eggert@twinsun.com>
8039 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8040 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8041 for the CDPATH problem. Document PWD.
8042 (Limitations of Builtins): Document the problem that "cd $foo" and
8043 "ls $foo" may refer to different directories in shells conforming
8044 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8045 example, since the old example is now out of date.
8047 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8048 FOO" and "ls FOO" talk about different directories; this catches
8049 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8050 spaghetti.
8052 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8053 of rolling our own unset.
8054 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8055 in practice we needn't worry about CDPATH if unset doesn't work.
8057 * Makefile.in, aclocal.m4, bin/Makefile.in,
8058 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8059 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8060 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8061 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8062 tests/Makefile.in: Regenerate with Automake 1.6.3.
8064 * config/config.guess, config/config.sub, config/mkinstalldirs:
8065 Update.
8067 * configure: Regenerate with self.
8069 2002-08-30 Kevin Ryde <user42@zip.com.au>
8071 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8072 default output.
8074 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8076 * bin/autom4te.in (Request::load): Correctly test for "do" read
8077 failure.
8079 2002-08-29 Akim Demaille <akim@epita.fr>
8081 * lib/Autom4te/General.pm (&xqx): New.
8082 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8083 hand, which is not portable.
8084 (&error): New.
8085 * bin/autom4te.in: Use them.
8086 Use &error instead of die.
8087 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8088 Adjust.
8090 2002-08-17 Paul Eggert <eggert@twinsun.com>
8092 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8093 default list of compilers to try, since it was long ago superseded
8094 by the ksh fc builtin. Suggested by Steven G. Johnson.
8096 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8098 * doc/autoconf.texi (Invoking autom4te): End the option table,
8099 fixing a bug introduced by the previous patch.
8100 (Limitations of Make): Add a 'target lookup' subentry in the
8101 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8103 2002-07-29 Mark D. Roth <roth@feep.net>
8105 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8106 options and use $AUTOM4TE_PATH.
8107 * doc/autoconf.texi: Remove documentation of autom4te
8108 --include-envvar and --site-macro-subdir options and document
8109 use of $AUTOM4TE_PATH.
8110 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8111 arguments from each language section.
8113 2002-07-29 Paul Eggert <eggert@twinsun.com>
8115 * doc/install.texi: Include copyright symbol in copyright notice.
8117 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8118 Replace with:
8119 (AM_MAKEINFOFLAGS): New macro.
8120 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8121 * Makefile.am (INSTALL): Use the new macros.
8122 Use -o rather than --output, since "missing" does not grok --output.
8124 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8126 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8127 comments do not always work. Never trust the exit status of
8128 `make -k'.
8130 2002-07-24 Kevin Ryde <user42@zip.com.au>
8132 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8133 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8135 2002-07-23 Paul Eggert <eggert@twinsun.com>
8137 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8138 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8139 apparently treats PATH="nonexistent" as if it contained ".".
8140 Bug reported by Stefan `Sec' Zehl.
8142 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8144 * doc/autoconf.texi (Limitations of Make): Mention the special
8145 handling of the obj/ directory by BSD make.
8147 2002-07-20 Kevin Ryde <user42@zip.com.au>
8149 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
8150 backslashes.
8152 2002-07-19 Akim Demaille <akim@epita.fr>

8161 2002-07-18 Akim Demaille <akim@epita.fr>
8163 Version 2.53b.
8165 2002-07-18 Akim Demaille <akim@epita.fr>
8167 * config/config.guess, config/config.sub: Update.
8169 2002-07-18 Akim Demaille <akim@epita.fr>
8171 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
8172 Automake's parts.
8174 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
8175 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
8176 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
8178 2002-07-18 Akim Demaille <akim@epita.fr>,
8179 Alexandre Duret-Lutz <duret_g@epita.fr>
8181 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
8182 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

8187 description of the tarname default.
8189 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
8191 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
8192 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
8193 latter was not run.
8195 2002-07-17 Akim Demaille <akim@epita.fr>
8197 * lib/Autom4te/General.pm (find_file): Browse the directories in
8198 the order they are given.
8200 2002-07-17 Akim Demaille <akim@epita.fr>

8203 * tests/wrapper.as: this.
8204 * tests/Makefile.am, configure.ac: Adjust.
8206 2002-07-17 Mark D. Roth <roth@feep.net>

8218 macro directory, remove note that include path directories are
8219 used in reverse order, and document --prepend-include option.
8220 * lib/autom4te.in: Use --prepend-include instead of --include.
8221 * tests/wrapsh.in: Use --prepend-include instead of --include.
8223 2002-07-17 Akim Demaille <akim@epita.fr>

8259 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
8261 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
8262 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
8263 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
8264 so that Emacs setups GNU style for perl-mode and cperl-mode.
8266 2002-06-27 Paul Eggert <eggert@twinsun.com>
8268 * config/install-sh: Quote $src. Prefer || to test's -o option,
8269 as per "Limitations of Builtins".
8270 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
8271 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
8273 * tests/mktests.sh: Use grep instead of fgrep, as per
8274 "Limitations of Builtins".
8276 2002-06-15 Paul Eggert <eggert@twinsun.com>
8278 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
8279 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
8280 so that we consistently test the just-built programs.
8281 * tests/wrappl.as: Likewise.
8283 2002-06-12 Paul Eggert <eggert@twinsun.com>
8285 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
8286 name, so that symlinks to 'autoconf' work properly. Bug reported
8287 by Bruno Haible.
8288 * bin/autoheader.in (AUTOM4TE): Likewise.
8289 * bin/autoreconf.in (autoconf, autoheader): Likewise.
8290 * bin/autoscan.in (autom4te): Likewise.
8291 * bin/autoupdate.in (autom4te): Likewise.
8293 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
8294 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
8295 on Solaris 2.5.1.
8297 2002-06-11 Andreas Schwab <schwab@suse.de>
8299 * doc/autoconf.texi: Add more dir entries.
8301 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
8303 * bin/autom4te.in ($cache): Don't define using `$me', the name
8304 of the cache should not depend on the name under which autom4te
8305 was installed.
8307 2002-06-07 Akim Demaille <akim@epita.fr>
8309 * tests/tools.at (autoconf: forbidden tokens, basic)
8310 (autoconf: forbidden tokens, exceptions): Adjust to the change of
8311 words in autom4te.in.
8313 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
8315 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
8316 _AC_LANG_PROGRAM_C_F77_HOOKS.
8318 2002-06-07 Akim Demaille <akim@epita.fr>
8320 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
8321 rename as...
8322 (AC_REPLACE_FNMATCH): this.
8323 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
8324 AC_FUNC_FNMATCH_GNU.
8326 2002-06-07 Akim Demaille <akim@epita.fr>
8328 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
8329 Rosetta Stone for Unix.
8331 2002-06-07 Akim Demaille <akim@epita.fr>
8333 * bin/autom4te.in (warn_forbidden): When rejecting a token,
8334 suggest m4_pattern_allow.
8335 Suggested by Adam J. Richter.
8337 2002-06-07 Akim Demaille <akim@epita.fr>
8339 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
8340 ac_config_libobj_dir.
8341 (AC_CONFIG_LIBOBJ_DIR): New.
8342 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
8343 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
8344 Use ac_config_libobj_dir to find the replacement files.
8345 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
8346 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
8347 (AC_REPLACE_FNMATCH_GNU): these.
8348 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
8349 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
8350 * tests/mktests.sh (ac_exclude_list): Don't check
8351 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
8353 2002-06-06 Paul Eggert <eggert@twinsun.com>
8355 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
8356 if ln doesn't work.
8357 * NEWS: Likewise.
8358 * doc/autoconf.texi (Configuration Links): Likewise.
8359 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
8361 2002-06-05 Paul Eggert <eggert@twinsun.com>
8363 * config/config.guess, config/config.sub, config/texinfo.tex:
8364 Update from masters.
8366 2002-05-29 Paul Eggert <eggert@twinsun.com>
8368 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
8369 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
8370 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):
8371 Likewise.

8382 * doc/autoconf.texi (Particular Programs): Document them.
8383 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.

8389 * NEWS, doc/autoconf.texi (Particular Types): Document it.

8391 instead of AC_MBSTATE_T, which never existed.
8393 2002-05-23 Akim Demaille <akim@epita.fr>
8395 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
8396 version of Autoconf that is discussed.
8398 2002-05-22 Paul Eggert <eggert@twinsun.com>
8400 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
8401 from the default list of compilers to try. Suggested by
8402 Kate Hedstrom.
8403 * NEWS: Document the above.
8404 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
8406 2002-05-17 Paul Eggert <eggert@twinsun.com>
8408 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
8409 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
8410 This improves on an earlier suggestion by H. Peter Anvin.
8412 2002-05-16 Paul Eggert <eggert@twinsun.com>
8414 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
8415 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
8416 Both macros now accept an optional source-dir arg.
8417 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
8419 * NEWS: Document this.
8420 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
8422 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
8423 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
8424 not for GNU extensions; this undoes part of the 2000-11-03 change,
8425 reverting to 2.13-compatible behavior.
8426 Add new optional argument DIR.
8427 (AC_FUNC_FNMATCH_GNU): New macro.
8429 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
8431 2002-05-08 Paul Eggert <eggert@twinsun.com>
8433 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
8434 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
8435 and it causes a 'test' syntax error if it fails.
8436 Bug reported by Stephen Gildea.
8438 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8439 If prototypes are supported, use them to check this at compile-time,
8440 instead of trying to check it at run-time. If we must do a run-time
8441 check, assume that setvbuf is standard when cross-compiling, as
8442 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8443 Bug reported by Paul D. Smith.
8445 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8446 argument specifying location of getloadavg.c. This removes a
8447 FIXME. This idea was taken from Jim Meyering's implementation in
8448 textutils.
8449 * doc/autoconf.texi (Particular Functions): Document this.
8450 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8451 that's what the code does; this fixes a bug reported by
8452 Paul D. Smith.
8454 2002-05-03 Akim Demaille <akim@epita.fr>
8456 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8457 autopoint instead of gettextize.
8458 ($uses_alocal): Rename as...
8459 ($uses_aclocal): this.
8460 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8461 Suggested by Bruno Haible.
8463 2002-05-03 Akim Demaille <akim@epita.fr>
8465 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
8467 2002-04-29 Paul Eggert <eggert@twinsun.com>
8469 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
8470 files to be 1 second older; just set them to be the same time.
8471 Also, sleep 1 second after the first aclocal, to work around
8472 problems with sub-second time stamps on the input files.
8474 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
8476 * doc/autoconf.texi: Mention "set -e -x" lossage
8477 under node "Limitations of Builtins".
8479 2002-04-29 Akim Demaille <akim@epita.fr>
8481 * doc/install.texi: Better wording for setting variables when
8482 running configure.
8483 From Christian Cornelssen.
8485 2002-04-29 Akim Demaille <akim@epita.fr>
8487 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
8488 of lack of $LINENO support, then the test will compare the $LINENO
8489 in testsuite vs. the lineno in the test file. This is wrong, of
8490 course.
8491 Be sure to protect it.
8492 Reported by Patrick Welche.
8494 2002-04-25 Akim Demaille <akim@epita.fr>
8496 * doc/autoconf.texi (Obsolete Macros): Typo.
8497 Reported by Vladimir Volovich.
8499 2002-04-25 Akim Demaille <akim@epita.fr>
8501 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
8502 than some of the input files, hence, on the second run of aclocal,
8503 if some of its input are younger, make them older.
8504 Suggested by Paul Eggert.
8506 2002-04-25 Akim Demaille <akim@epita.fr>
8508 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
8509 Thanks to Paul Eggert.
8511 2002-04-25 Akim Demaille <akim@epita.fr>
8513 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
8514 and ac_subst_vars be sh variables containing the list of
8515 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
8516 DEFAULT diversion.
8517 (_AC_INIT_PREPARE): Use them to log them.
8518 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
8519 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
8520 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
8521 _AC_SUBST_FILES and _AC_SUBST_VARS.
8522 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
8524 2002-04-24 Akim Demaille <akim@epita.fr>
8526 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
8527 autoheader, so that automake does not complain about a missing
8528 config.h.in that was to be created.
8530 2002-04-23 Akim Demaille <akim@epita.fr>
8532 * bin/autoheader.in (parse_args): --warning takes an argument.
8533 Fixes PR/220.
8535 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
8537 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

8548 2002-04-22 Akim Demaille <akim@epita.fr>
8550 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
8551 comma.
8552 Reported by Gregory Giannoni.
8554 2002-04-22 Akim Demaille <akim@epita.fr>
8556 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
8557 Fixes false failures on Darwin.

8563 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

8582 Minor spelling and grammar fixes.
8584 * doc/autoconf.texi: Follow the outline suggested in the GNU
8585 Sample Texts sections of the Texinfo 4.2 manual. Most
8586 importantly, this makes sure that the copyright notices appear in
8587 all output formats. You probably need Texinfo 4.2 to generate
8588 the manual now.
8590 Fix some bugs when using "$@" when there might be zero positional
8591 arguments in cases where this matters.

8612 that is not portable to Zsh.
8614 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
8616 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
8617 from aclocal.m4 too.
8619 2002-04-12 Akim Demaille <akim@epita.fr>
8621 * tests/wrappl.as: New, M4sh precursor of wrappl.in.

8637 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
8639 Adjust Autoconf and Autotest.

8642 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
8643 * lib/autotest/general.m4 (AT_INIT): Likewise.
8644 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8645 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
8646 AS_SHELL_SANITIZE.
8648 Use this M4sh to generate Autoconf's shell scripts.
8650 * tests/wrapsh.as: New, precursor of wrapsh.in.
8651 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
8652 on Autotest and M4sh.
8653 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).

8689 Extracted from...
8690 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8691 (AC_CONFIG_LINKS): here.
8692 Adjust.
8693 Don't use the KILL diversion, as it kills spurious output, which
8694 results in failures being hidden.
8695 Use m4_defn where appropriate.
8696 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8697 after the second argument.
8698 Use m4_defn.
8699 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8700 syntax, as it is provided by M4sugar.

8763 * doc/autoconf.texi (Assignments): Document the problem.
8765 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8767 * doc/autoconf.texi (Limitations of Make): Mention more issue
8768 about VPATH, overriding of macros in sub-makes, and handling of
8769 SHELL.
8771 2002-03-21 Paul Eggert <eggert@twinsun.com>
8773 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8774 problem with here-document buffer boundaries.

8805 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8806 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8807 back on AS_DIRNAME to compute prefixes otherwise; this is
8808 roughly what mkinstalldirs does. That way, we need not have
8809 our own filename disassembler. The old disassembler did not
8810 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8812 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8813 Create at_test_all by a series of assignments,
8814 not by a single assignment of a long string. The latter causes ksh
8815 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8816 presumably because of a buffer overrun.
8818 2002-03-14 Paul Eggert <eggert@twinsun.com>
8820 * lib/autotest/general.m4 (at_times_skip):
8821 Renamed from at_times. Now a boolean.
8822 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8823 says 'times: not found'.
8825 2002-03-14 Akim Demaille <akim@epita.fr>
8827 * bin/autoreconf.in (&study_gettextize): New.
8828 (&autoreconf): Handle newest gettextize.

8830 Suggested by Andreas Schwab.

8841 2002-03-13 Akim Demaille <akim@epita.fr>
8843 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
8844 -p'.
8845 From Bob Proulx.
8847 2002-03-12 Akim Demaille <akim@epita.fr>
8849 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
8850 m4_require.
8852 2002-03-11 Andreas Schwab <schwab@suse.de>
8854 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
8855 does not do it if --with-lispdir is given.
8857 2002-03-08 Akim Demaille <akim@epita.fr>
8859 Version 2.53.
8861 2002-03-08 Akim Demaille <akim@epita.fr>

8870 2002-03-08 Akim Demaille <akim@epita.fr>
8872 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8873 aliases the actual variables, and modifications of the former
8874 affect the latter.
8876 2002-03-08 Akim Demaille <akim@epita.fr>
8878 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8879 because of C-c: have m4 output in tmp files, then mv them.
8881 2002-03-08 Akim Demaille <akim@epita.fr>
8883 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

8909 parallel builds.
8911 2002-03-04 Akim Demaille <akim@epita.fr>
8913 * doc/autoconf.texi (Transforming Names): Equality between target
8914 and host is irrelevant.
8915 (Specifying Names, Canonicalizing): Remove all references to the
8916 backward compatibility hooks. Rather, collect them all into...
8917 (Hosts and Cross-Compilation): this new section.
8918 * doc/install.texi (System Type): Ditto.
8919 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8920 that `--host' implies cross-compilation.
8922 2002-03-04 Akim Demaille <akim@epita.fr>
8924 * doc/autoconf.texi (Evaluation Macros): New.
8925 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8926 useless.
8927 (_m4_foreach): Define the variant with immediate evaluation so
8928 that it contains exactly the items, not an expression which
8929 evaluation is the current item.
8930 (m4_re_string, m4_re_word): Don't over quote them.
8932 2002-03-04 Akim Demaille <akim@epita.fr>
8934 Instead of having stacking `shift's evaluated at the end, let
8935 `foreach' loops immediately evaluate them.
8937 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8938 $*. This is the n-th time I change my mind, but hopefully this is
8939 the last...
8940 (m4_lquote): New.
8941 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8942 efficient.
8943 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8944 it was only a hack for m4_text_wrap.
8945 (m4_car2): Remove, replaced by...
8946 (m4_cdr): New.
8947 (_m4_foreach): Adjust.
8948 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8949 m4_bpatsubst for clarification.
8951 2002-03-04 Akim Demaille <akim@epita.fr>
8953 * doc/autoconf.texi (Changequote is Evil): New.

8977 2002-02-25 Akim Demaille <akim@epita.fr>
8979 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
8980 From Akinori Musha.
8982 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
8984 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
8985 translate \r\n to \n.
8987 2002-02-07 Akim Demaille <akim@epita.fr>

8998 2002-02-07 Akim Demaille <akim@epita.fr>
9000 Fix Autoconf PR/207:
9001 AC_PREFIX_PROGRAM fails with dashed program names
9003 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

9005 Now it also works for shell variables.

9010 case/esac.
9012 2002-02-06 Akim Demaille <akim@epita.fr>
9014 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
9015 case/esac, some shells don't support it.
9016 Reported by Zack Weinberg.
9017 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
9019 2002-02-06 Akim Demaille <akim@epita.fr>
9021 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9022 sure not to introduce newlines in at_groups.
9023 * lib/autotest/Makefile.am (autotest.m4f): Typo.
9025 2002-02-06 Akim Demaille <akim@epita.fr>
9027 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9028 is not available.
9030 2002-02-05 Paul Eggert <eggert@twinsun.com>

9033 Describe HP-UX cc bug workaround more accurately.

9035 not unsigned long.
9036 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9037 cross-compilers, too. This undoes some of the most recent change
9038 to this file.
9040 2002-02-05 Akim Demaille <akim@epita.fr>
9042 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9043 to make sure they are up to date when `check' is run.

9047 * doc/autoconf.texi (Making testsuite Scripts): Document
9048 package.m4.
9050 2002-02-05 Akim Demaille <akim@epita.fr>

9054 2002-02-05 Akim Demaille <akim@epita.fr>
9056 Implement `autom4te --freeze'.
9058 * bin/autom4te.in (&freeze): New.
9059 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9060 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9062 2002-02-05 Akim Demaille <akim@epita.fr>
9064 * bin/autom4te.in (&parse_args): Implement `frozen files are
9065 optional are the sum of the previous files on the command line'.
9066 Also, pass `--reload-state=' on them, so...
9067 (handle_m4): don't.
9068 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9069 (M4sh): Rely on M4sugar.
9070 (Autotest, M4sh, M4sugar): Use frozen files.
9072 2002-01-31 Akim Demaille <akim@epita.fr>

9075 * doc/autoconf.texi (Initializing configure): Adjust.
9077 2002-01-30 Akim Demaille <akim@epita.fr>
9079 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9080 alphanumeric to `-' instead of `_'.
9082 2002-01-30 Akim Demaille <akim@epita.fr>
9084 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9085 for plain code, the other for cross-compilation code. The latter
9086 is now run with GCC only.
9087 * doc/autoconf.texi (Compilers and Preprocessors): New.

9091 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
9092 values.
9093 * doc/autoconf.texi (Initializing configure): Explain how to
9094 change AC_INIT default values.
9096 2002-01-29 Akim Demaille <akim@epita.fr>
9098 * tests/torture.at (Configuring subdirectories): Use configure.in,
9099 so that aclocal 1.4 works.
9100 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9102 2002-01-28 Akim Demaille <akim@epita.fr>
9104 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9105 needs an argument.
9107 2002-01-28 Akim Demaille <akim@epita.fr>
9109 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9110 AUTOTEST_PATH *after* it was set.
9111 Don't put `.' in the PATH: the user should be precise and `./' if
9112 needed. In addition, given that the test suite does some `cd', if
9113 `.' is in the path, the `tested programs' sections will report
9114 programs found in the test suite's directory, while during the
9115 tests (performed in their own directory), these programs are no
9116 longer visible. In other words, the results is confusing and
9117 useless.
9118 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9120 2002-01-24 Akim Demaille <akim@epita.fr>
9122 Version 2.52g.

9132 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
9133 Bourne. Use /bin/sh.
9134 From Andreas Buening.
9136 2002-01-24 Akim Demaille <akim@epita.fr>
9138 * config/config.guess, config/config.sub, config/texinfo.tex:

9160 2002-01-21 Akim Demaille <akim@epita.fr>
9162 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
9163 message on invalid options.
9164 * bin/autom4te.in (parse_args): Don't use
9165 Autoconf::General::getopt with non valid options.
9167 2002-01-17 Jim Meyering <meyering@lucent.com>
9169 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
9170 $ac_cv_exeext so we don't use an old, invalid, cached value.
9172 2002-01-11 Akim Demaille <akim@epita.fr>
9174 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim

9184 package.m4, since is really depends upon configure.ac, not
9185 configure.
9186 * doc/autoconf.texi (testsuite Scripts): Adjust.
9187 * tests/Makefile.am (package.m4): New.
9188 EXTRA_DIST it since its a source.
9190 2002-01-06 Akim Demaille <akim@epita.fr>
9192 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9193 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9194 and PACKAGE_BUGREPORT from here...
9195 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9196 arguments.
9197 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
9198 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
9199 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
9200 * tests/tools.at (autoheader): Adjust.
9201 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
9203 2002-01-06 Akim Demaille <akim@epita.fr>

9207 2002-01-03 Akim Demaille <akim@epita.fr>
9209 * doc/autoconf.texi (Output): Improved wording regarding use of
9210 AC_OUTPUT.

9216 sometimes needing writable input.

9222 2001-12-14 Akim Demaille <akim@epita.fr>
9224 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9225 trailing files, don't apply `-rf' to files which might not be
9226 created by configure (core, core.*, and *.core), but just `rm -f'.
9227 Suggested by Jonathan Kamens.
9229 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9231 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
9233 2001-12-14 Akim Demaille <akim@epita.fr>
9235 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
9237 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

9265 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
9266 Remove $filepath, useless.
9267 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
9268 variables, they are really part of the tokens.
9269 Split the input line on spaces and then look for tokens.
9270 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9271 because of `lex$U.$(OBJEXT)'.
9272 (&scan_files): Use "@list" instead of join.
9273 * doc/Makefile.am (CLEANFILES): Add *.fns.
9275 2001-11-26 Akim Demaille <akim@epita.fr>
9277 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
9278 Remove, replaced by...
9279 * tests/wrappl.in: Be common for all the Perl executables.
9280 In particular autoscan and autoheader want -I.
9281 * configure.ac: Adjust.
9282 * lib/autoscan/headers: errno.h is portable.
9284 2001-11-26 Akim Demaille <akim@epita.fr>

9287 Use it.

9301 comment made the whole line be ignored.
9303 2001-11-26 Akim Demaille <akim@epita.fr>
9305 * doc/autoconf.texi (Using an Autotest Test Suite): New.

9317 top_srcdir, builddir and top_builddir.
9318 Use `at_*dir' relatively to the directory containing the
9319 suite, use `*dir' when relatively to the current group dir.

9323 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
9324 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
9325 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
9326 spelling errors.
9328 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9330 * doc/autoconf.texi (Using System Type): Add an example of `case
9331 $host' usage so people quit using `case $target' everywhere.
9333 2001-11-22 Akim Demaille <akim@epita.fr>
9335 * doc/autoconf.texi (Installation Directory Variables): Englishoes
9336 spotted by Jim Meyering.
9338 2001-11-16 Paul Eggert <eggert@twinsun.com>
9340 This patch implements a `long double' suggestion by Oliver Kiddle.
9342 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9343 static, to catch errors if the value isn't known at compile-time
9344 and the compiler supports dynamic arrays. Change its name from
9345 `_array_' to `test_array' to avoid potential name clashes.
9346 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9347 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9348 better than double. Catch a bug in GCC 2.95.2 x86.
9349 * doc/autoconf.texi (C Compiler): Document the above.
9350 * NEWS: Likewise.
9352 2001-11-13 Akim Demaille <akim@epita.fr>
9354 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9355 hand.
9356 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9358 2001-11-13 Akim Demaille <akim@epita.fr>
9360 * lib/autotest/general.m4 (AT_INIT): After having run the test
9361 group, go back to the initial directory, not to at_suite_dir.
9363 2001-11-13 Akim Demaille <akim@epita.fr>
9365 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9366 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9367 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9368 option.
9369 (AT_CHECK_CONFIGURE): Use absolute paths.
9370 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9371 The problem is still the old one: there is no means in M4 (that I
9372 know about) to create a defining macro, because there is no means
9373 to create `$1' etc., therefore, the defining macro ``swallows''
9374 all the arguments meant to the defined macro.
9376 2001-11-13 Akim Demaille <akim@epita.fr>
9378 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9379 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9380 configure.ac.
9381 * tests/aclocal.m4: Remove, as it is no longer used.
9383 2001-11-13 Akim Demaille <akim@epita.fr>
9385 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9386 variable names when referring to a single test group, or to
9387 `suite' when referring to the whole test suite.
9388 `at_last_test' is removed: m4 compute at_format itself.
9389 (at_stdout, at_stder1, at_stderr): New variables.
9390 (AT_CHECK): Use them.
9392 2001-11-13 Akim Demaille <akim@epita.fr>
9394 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9395 in PATH.
9396 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9397 Do it as soon as a test fails, don't wait till the end of the test
9398 suite.
9399 Don't remove $as_me.[0-9]*, since these files no longer exist.
9401 2001-11-13 Akim Demaille <akim@epita.fr>
9403 * tests/tools.at: Use absolute paths, since we are no longer run
9404 in place.
9406 2001-11-13 Akim Demaille <akim@epita.fr>
9408 Now that tests are running in their own private dir, there is no
9409 need to list the files to remove at the end of tests groups.
9411 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
9412 (AT_data_files, at_data_files): Remove.
9413 (AT_CLEANUP, AT_DATA): Simplify.
9414 (AT_INIT): Adjust.
9415 Remove the group dir if !debug && !failed.
9416 * tests/atspecific.m4: Adjust.
9418 2001-11-13 Akim Demaille <akim@epita.fr>
9420 Start a new layout for Autotest: `testsuite' creates
9421 `testsuite.dir' in which the at-check-line etc. files are to be
9422 found, and `testsuite.dir/003' where the test group 3 is run.
9424 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
9425 at_check_line_file, at_format, at_test_normalized, at_group_dir
9426 are new variables.
9427 Create the directories.
9428 Use absolute paths for at- files.
9429 (AT_CHECK): Adjust.
9431 2001-11-11 Michael Matz <matz@kde.org>
9433 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
9434 (m4_car2): New.
9435 (m4_car): Properly quote arguments.
9437 2001-11-13 Akim Demaille <akim@epita.fr>
9439 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9440 with stricter rules on LIBOBJS.
9442 2001-11-12 Paul Eggert <eggert@twinsun.com>
9444 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9445 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9446 __PROTOTYPES too.
9448 2001-11-12 Akim Demaille <akim@epita.fr>
9450 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9452 2001-11-12 Akim Demaille <akim@epita.fr>
9454 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,

9456 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9457 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9458 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9459 specify to what the macro should be defined (typically to 1).
9461 2001-11-12 Akim Demaille <akim@epita.fr>
9463 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9464 From Jim Meyering.
9466 2001-11-12 Akim Demaille <akim@epita.fr>
9468 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9469 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
9470 definition used by Automake where LEX is +/- "${missing} lex" and
9471 `missing' itself contains variables.
9473 2001-11-12 Akim Demaille <akim@epita.fr>
9475 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
9476 Now that M4sh pushes BODY, the comments were output at the end of
9477 the test suites.
9479 2001-11-08 Akim Demaille <akim@epita.fr>
9481 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
9482 that we can trace macros from aclocal.m4.
9483 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
9484 obsoleted, and redirect to the former anyway.
9485 Reported by Ralf Corsepius.
9487 2001-11-08 Akim Demaille <akim@epita.fr>
9489 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
9490 processed only if present.
9491 * tests/torture.at (Configuring subdirectories): Use autoreconf
9492 instead of successive calls to autoconf.
9493 Add a nonexistent subdirectory to exercise the patch above.
9494 Reported by Ralf Corsepius.
9496 2001-11-08 Kevin Ryde <user42@zip.com.au>
9498 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
9499 doesn't accept .S files.
9501 2001-11-07 Akim Demaille <akim@epita.fr>
9503 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
9504 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
9505 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
9506 * bin/autom4te.in (warn_forbidden): New.
9507 (handle_output): Use it.
9508 Read m4_pattern_forbid with messages.
9510 2001-11-05 Akim Demaille <akim@epita.fr>
9512 * bin/autom4te.in (--normalize): Remove.
9513 * lib/autom4te.in: Adjust.
9515 2001-11-05 Akim Demaille <akim@epita.fr>
9517 * tests/Makefile.am (testsuite): Rename this target as...
9518 ($(TESTSUITE)): this.
9519 From Nicolas Joly.
9521 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
9523 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
9524 the --prefix option, also remove it's argument.
9526 2001-11-05 Akim Demaille <akim@epita.fr>
9528 * doc/autoconf.texi (testsuite Invocation): Update.
9529 (Writing testsuite.at): Update.
9531 2001-11-03 Akim Demaille <akim@epita.fr>
9533 * doc/autoconf.texi: s/@code/@command/ where appropriate.
9535 2001-11-03 Akim Demaille <akim@epita.fr>
9537 * lib/Autom4te/General.pm: (&catfile, &canonfile)
9538 (&file_name_is_absolute): New, wrappers around routines from
9539 File::Spec.
9540 Use and export them.
9541 (&find_configure_ac): Optionally take a directory where to look at.
9542 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
9543 the arguments.
9544 Default @ARGV to `.', not find_configure_ac.
9545 (&autoreconf): Argument is a directory.
9546 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
9547 * doc/autoconf.texi (autoreconf Invocation): Update.
9549 2001-11-03 Akim Demaille <akim@epita.fr>
9551 * lib/Autom4te/General.pm (@export_vars, @export_subs)
9552 (@export_forward_subs): New.
9553 Add basename, dirname, and fileparse.
9554 (@EXPORT): Adjust.
9555 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
9556 Don't look for aclocal flags if we already know aclocal is not
9557 used.
9558 Move aclocal.m4t only if it exists.
9559 Reported by Ezra Peisach.
9561 2001-11-03 Akim Demaille <akim@epita.fr>
9563 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
9564 passed on command line, defaulting to ./configure.ac if present.
9565 (&maybe_autoreconf, File::Find): Remove, unused.
9566 (&autoreconf): If autoconf is not used, don't try to trace.
9568 2001-11-02 Akim Demaille <akim@epita.fr>
9570 * configure.ac: Bump to 2.52g.
9572 2001-11-02 Akim Demaille <akim@epita.fr>
9574 Version 2.52f.
9576 2001-11-02 Akim Demaille <akim@epita.fr>
9578 * config/config.guess, config/config.sub, doc/standards.texi:
9579 * config/lispdir.m4: Update from masters.
9580 * configure.ac: Bump to 2.52f.
9582 2001-11-02 Akim Demaille <akim@epita.fr>
9584 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
9585 Don't run aclocal when aclocal.m4 is not from aclocal.
9586 From Ezra Peisach.
9587 Don't run libtoolize and gettextize if --install is not given.
9589 2001-11-01 Paul Eggert <eggert@twinsun.com>
9591 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
9592 be invoked before _AS_LINENO_PREPARE.
9593 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9594 than character ranges.
9596 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9597 invoking AS_BASENAME. Set the locale variables to 'C' if
9598 possible, as POSIX requires this to get the traditional
9599 behavior.
9600 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9602 2001-10-31 Paul Eggert <eggert@twinsun.com>
9604 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9605 with {}, as that triggers a bug in Bash 2.05.
9607 (_AS_LINENO_PREPARE): Use Sed rather than
9608 Awk. Fix the sed prepass to work even if there are multiple
9609 instances of $LINENO on the same line. Do not substitute for
9610 other variables like $LINENOT. Do not check file dates; such a
9611 check is unreliable on sufficiently fast machines, and removing
9612 the check makes the code simpler and more reliable. Check for
9613 output and chmod failures.
9615 * doc/autoconf.texi (Special Shell Variables): Document
9616 the above.
9618 2001-10-31 Akim Demaille <akim@epita.fr>
9620 * tests/Makefile.am (atconfig): Remove this target, Automake
9621 handles it now.
9623 2001-10-31 Akim Demaille <akim@epita.fr>
9625 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
9626 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
9627 provided, while it is optional.
9628 * configure.ac: Adjust.
9630 2001-10-26 Paul Eggert <eggert@twinsun.com>
9632 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
9633 lib/Autom4te/Struct.pm:
9634 Require Perl 5.005_03 instead of just 5.005, as some tests fail
9635 with 5.005_02.
9637 * doc/autoconf.texi (Special Shell Variables): Document some
9638 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
9640 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
9641 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
9642 eval $LINENO is not portable in practice.
9644 2001-10-24 Akim Demaille <akim@epita.fr>
9646 * lib/Autom4te/General.pm (backname): New.
9648 2001-10-24 Akim Demaille <akim@epita.fr>
9650 * m4/: Remove, merged into...
9651 * config/: here.
9653 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
9655 * doc/autoconf.texi (Shellology): Mention the problems with bash
9656 2.05's use of ANSI quoting in its `set' builtin.
9658 2001-10-22 Paul Eggert <eggert@twinsun.com>
9660 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
9661 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
9662 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
9663 POSIX decided to standardize on the int flavor of strerror_r.
9664 Always do char* test, as there's no reason not to.
9665 Assign to a char* var, to catch strerror_r that returns int*.
9667 * doc/autoconf.texi (Particular Functions):
9668 Document the above changes. Also, document the fact that
9669 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
9671 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
9673 2001-10-20 Akim Demaille <akim@epita.fr>
9675 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
9676 the executable was missing from the log.
9678 2001-10-20 Akim Demaille <akim@epita.fr>
9680 * lib/Autom4te/General.pm (&update_file): If destination is
9681 unchanged, remove the source.
9682 (&up_to_date_p): Don't be verbose, be debug.
9683 * bin/autoreconf.in: No longer support --m4dir.
9684 (&autoreconf): Display the full path of the configure.ac we are
9685 studying.
9686 Trace it only once.
9687 Be sure to honor --force with gettextize.
9688 Always run aclocal.
9689 * doc/autoconf.texi: Adjust.
9691 2001-10-20 Akim Demaille <akim@epita.fr>
9693 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9694 Remove, dead.
9695 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9696 `intl' is already present, as it refuses unless --force.
9697 (&parse_args): Use -I, --include instead of the old Autoconf
9698 options.
9699 ($localdir, $autoconf_dir): Remove.
9700 (@include): New.
9701 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9703 2001-10-19 Jens Petersen <petersen@redhat.com>
9705 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

9708 2001-10-19 Akim Demaille <akim@epita.fr>
9710 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated

9715 2001-10-19 Akim Demaille <akim@epita.fr>
9717 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a

9719 From Russ Allbery.
9721 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
9723 * bin/autoreconf.in (autoreconf): Display the path to the
9724 configure.ac being studied.
9726 2001-10-18 Paul Eggert <eggert@twinsun.com>
9728 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
9729 long, to work around a bug in the HP C compiler version HP92453-01
9730 B.11.11.23709.GP.
9732 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
9733 (AS_BASENAME_EXPR): New macro.
9734 (AS_BASENAME_SED): Do not assume GNU sed semantics.
9735 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
9736 and fall back on 'sed' only if the other two fail. This makes
9737 AS_BASENAME act more like AS_DIRNAME.
9738 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
9739 contains white space.
9740 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
9741 Use AS_DIRNAME, since I think it's now DOS-friendly.
9742 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9743 Allow "dirname //FOO" to return either / or //, as POSIX allows
9744 either behavior.
9746 2001-10-10 Akim Demaille <akim@epita.fr>
9748 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
9749 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
9750 From Eric Sharkey.
9752 2001-10-10 Akim Demaille <akim@epita.fr>
9754 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

9758 2001-10-10 Akim Demaille <akim@epita.fr>
9760 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)
9761 (AC_INCLUDES_DEFAULT): Move to...

9763 * lib/autoconf/types.m4: Comment changes.
9764 * doc/autoconf.texi: Specify where the default includes are used
9765 in the macro prototypes.

9770 transition code.
9772 2001-10-08 Akim Demaille <akim@epita.fr>

9778 (Autoconf): Use it.
9780 2001-10-08 Akim Demaille <akim@epita.fr>
9782 * bin/autoreconf.in (autoreconf): Run libtoolize when appropriate.
9784 2001-10-08 Akim Demaille <akim@epita.fr>
9786 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9787 * bin/autoreconf.in (autoreconf): Run gettextize when appropriate.

9791 * tests/tools.at (AT_CHECK_PERL_SYNTAX): Check autoreconf.
9792 (Syntax of the shell scripts): Don't.

9797 2001-10-08 Akim Demaille <akim@epita.fr>
9799 * bin/autoreconf.in: Rewrite in Perl.
9800 * configure.ac: Adjust.

9890 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

10009 * tests/fortran.at (GNU Fortran 77): there.
10010 * doc/autoconf.texi (autoconf Invocation): Fix the example:
10011 AC_TRY_RUN is about compilation, not shell commands.
10012 (Test Programs): AC_TRY_RUN works as used to be advertised.
10014 2001-09-27 Akim Demaille <akim@epita.fr>
10016 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
10017 Raja R Harinath:

10020 enough.

10043 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
10044 builddir, buildpath, top_builddir, and top_buildpath.
10045 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
10046 the current directory.

10071 * doc/autoconf.texi (Common Shell Constructs): Rename as...

10118 2001-09-22 Akim Demaille <akim@epita.fr>

10123 `$LINENO' support replacement when not supported.
10124 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
10125 them explicitly to be sure they are not output before this section

10135 character (u: -> ue) in a code comment.
10136 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know

10163 * lib/autotest/general.m4: Replace occurrences of ':' in
10164 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
10166 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10168 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
10169 arguments. Fixed a typo.
10171 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10173 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

10185 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10187 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10188 already have $file). Set output files to binary mode (helps avoid
10189 CR issues on DOSish systems).
10191 2001-09-19 Akim Demaille <akim@epita.fr>
10193 * lib/autotest/general.m4: Englishoes.
10194 From Tim Van Holder and Alexey Mahotkin.
10196 2001-09-18 Paul Eggert <eggert@twinsun.com>
10198 * doc/autoconf.texi (Common Shell Constructs): New node,
10199 documenting AS_DIRNAME.
10200 (Limitations of Usual Tools): Refer to it when discussing dirname.
10201 Also, update discussion of POSIX standard to reflect latest draft.
10203 * lib/autoconf/c.m4:
10204 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
10206 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10207 Do not pass a first argument with leading '-'
10208 to expr, by parenthesizing initial integers that might be negative.
10210 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10211 now merely checks whether it is an error to pass an argument
10212 to getpgrp.
10214 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10215 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
10216 whether it is a (compile-time) error to pass an argument to
10217 getpgrp. This simpler test supports the revised documentation,
10218 and is all that AC_FUNC_GETPGRP's users really need.
10220 2001-09-18 Akim Demaille <akim@epita.fr>
10222 * doc/autoconf.texi (Limitations of Make) <$<>: New.

10233 correctly.
10234 Add test for AS_BASENAME.
10235 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10236 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10237 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10238 * tests/base.at: Fixed the expected responses. The old ones were
10239 one line out...
10240 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10241 the documentation claims it should (and how it behaved in 2.13).
10243 2001-09-18 Akim Demaille <akim@epita.fr>
10245 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in

10250 No longer to be shipped.

10253 * lib/autoconf/status.m4: Adjust.
10254 Use `m4_PACKAGE_STRING'.
10255 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now

10257 Expect `package.m4' to define the package signature.
10258 * lib/autom4te.in (Autotest): Add `package.m4?'.
10259 * tests/Makefile.am (package.m4): New.

10287 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10288 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10289 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10290 when they don't exist.
10292 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
10293 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
10294 need it.

10297 version with the version used by fileutils 4.1, except use

10301 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
10303 2001-09-13 Akim Demaille <akim@epita.fr>

10343 * lib/autotest/general.m4 (AT_INIT): Create and remove
10344 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

10434 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,

10455 2001-09-05 Akim Demaille <akim@epita.fr>
10457 Be ready to handle filenames as stupid as `dnl.at', for if even
10458 the maintainer is dumb enough to do that...
10460 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
10461 excellence in M4 quotation: consider `__file__' is active.
10463 And BTW, when invoking m4, pass the --include in the right order:
10464 the wrong one.
10466 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
10467 4m.

10491 CVS GNU M4 doesn't like `undefine(undefined)'.
10493 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
10494 New, extracted from main.
10495 Use IO::File wherever possible.
10496 (input.m4): Be constant, use -I instead of hard coding $tmp.
10497 Therefore be a quoted heredoc.
10498 Don't invoke `_au_disable', since ac was not loaded, but just
10499 `unm4.m4'.
10501 2001-08-31 Akim Demaille <akim@epita.fr>
10503 Version 2.52d.

10526 2001-08-31 Akim Demaille <akim@epita.fr>
10528 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
10529 (testsuite Scripts): There is no such thing as `atconfig.in'.
10530 And actually one diagram is missing: test suite runtime.
10532 2001-08-31 Akim Demaille <akim@epita.fr>
10534 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
10535 inverse order.
10537 2001-08-31 Akim Demaille <akim@epita.fr>
10539 * bin/autoupdate.in (@include): `installcheck' revealed the path
10540 to m4sugar was lacking!
10542 2001-08-31 Akim Demaille <akim@epita.fr>
10544 * man/Makefile.am (.x.1): We really have to pass
10545 autom4te_perllibdir.
10547 2001-08-31 Akim Demaille <akim@epita.fr>
10549 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
10550 debug scripts, in particular passing explicitly listed tests to
10551 run is stupid.
10553 2001-08-31 Akim Demaille <akim@epita.fr>
10555 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
10556 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
10557 Use directly autom4te, not autoconf.

10560 2001-08-31 Akim Demaille <akim@epita.fr>
10562 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

10571 * bin/autom4te.in (&parse_args): Die on unknown languages.
10572 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
10573 need for autoconf.
10574 Promote --include over --macrodir and other obsolete options.
10576 2001-08-31 Akim Demaille <akim@epita.fr>

10582 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
10583 (autoheader): Pass --force since the test suite goes too fast for
10584 the time stamps.
10585 Adjust to the new autoheader messages.
10587 2001-08-31 Akim Demaille <akim@epita.fr>
10589 * bin/autoheader.in: Handle the acconfig.h etc. junk files.

10599 Drop AC_MACRODIR dead for real.
10600 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
10601 `autoheader: `config.hin' is created'.
10602 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
10604 2001-08-31 Akim Demaille <akim@epita.fr>
10606 * bin/autoheader.in: Rewrite in Perl.

10609 2001-08-31 Akim Demaille <akim@epita.fr>
10611 * bin/autoconf.in (--include, -I): New option.
10612 Map --localdir, --autoconf-dir onto it.
10613 Forward autom4te's options instead of interpreting them.
10614 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
10615 There is no such envvar since the inception of autom4te.cfg.
10616 * bin/autom4te.in (&parse_args): Uniquify `@include'.
10617 * bin/autoupdate.in: Adjust, and perform more control.

10623 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
10624 * bin/autom4te.in (&find_file): Support `FILE?' standing for
10625 optionally `FILE'.
10626 Use -e, not -f, since /dev/null for instance is OK.
10627 (&parse_args): Adjust.
10628 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
10630 2001-08-31 Akim Demaille <akim@epita.fr>
10632 * configure.ac: Also find tested executables in bin.
10633 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
10634 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
10635 installed peer executables, only PATH is allowed to resolve it.
10636 Pass `autoconf_dir' via options, not via invisible envvars.
10637 * lib/Autom4te/General.pm (&find_peer): Remove.
10638 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
10639 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
10640 * man/Makefile.am: Let help2man rely on PATH instead of trying to
10641 find the executables for it.
10642 * tests/Makefile.am: Major cleanup. Too lazy to document...
10643 * tests/atlocal.in: Remove all the obscure envvar manipulations.
10644 We only need PERL.
10645 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
10646 indeed related to running the test suite, while passing
10647 --autoconf-dir and others is related to running non installed
10648 Autoconf executables. So don't do that, leave it to...
10649 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
10650 * tests/autoscan: New.
10651 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
10652 refer to library files: rely on --language.
10654 2001-08-29 Akim Demaille <akim@epita.fr>
10656 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

10659 2001-08-29 Akim Demaille <akim@epita.fr>
10661 * doc/autoconf.texi: Strip the @nodes.
10662 Suggested by Paul Eggert.

10665 2001-08-29 Akim Demaille <akim@epita.fr>
10667 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
10668 Suggested by Paul Eggert.
10670 2001-08-29 Akim Demaille <akim@epita.fr>
10672 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
10673 download in a tmp dir.
10675 2001-08-29 Akim Demaille <akim@epita.fr>
10677 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
10678 case insensitive OSes out there :(

10688 (&parse_args): Support --mode, --set, and --melt.
10689 * bin/autoconf.in: Simplify and adjust.
10690 * tests/Makefile.am (AUTOMAKE): Use --set.
10691 * tests/atlocal.in: Adjust.
10692 * BUGS: distcheck and check are weak.
10694 2001-08-29 Akim Demaille <akim@epita.fr>
10696 * lib/autotest/general.m4: Use
10697 foo=`(command) 2>/dev/null`
10698 not
10699 foo=`command` 2>/dev/null
10700 (at-devnull): Rename as...
10701 (AT-devnull): this.
10702 (--clean): Remove AT-* files too.
10703 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
10704 Reported by Nicolas Joly.
10706 2001-08-28 Akim Demaille <akim@epita.fr>
10708 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

11149 2001-08-15 Akim Demaille <akim@epita.fr>
11151 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
11152 don't waste time running `autoupdate --version' works.
11153 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
11155 2001-08-13 Akim Demaille <akim@epita.fr>
11157 * doc/autoconf.texi (ma): Rename this index as...

11171 duration of the test suite.
11173 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
11175 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
11176 endianness for comparison instead of relying on AT_CHECK_ENV.
11178 2001-08-11 Paul Eggert <eggert@twinsun.com>
11180 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
11181 to the INSTALL file.
11183 2001-08-11 Paul Eggert <eggert@twinsun.com>

11210 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
11212 * tests/semantics.at (AC_C_BIGENDIAN): New test.
11214 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11216 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
11217 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
11218 * doc/autoconf.texi (C Compiler Characteristics): Update
11219 documentation for AC_C_BIGENDIAN.
11221 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11223 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11224 magic values from an object file when cross-compiling.
11225 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11227 2001-08-10 Akim Demaille <akim@epita.fr>
11229 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11230 effects.
11231 Suggested by Russ Allbery.
11233 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11235 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11236 current $prefix to the sub-configures.
11238 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11240 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
11241 extension (needed on BeOS). Reported by Guido van Rossum.
11243 2001-08-09 Akim Demaille <akim@epita.fr>
11245 * bin/autom4te.in ($icache): Load it only if older than autom4te.
11247 2001-08-07 Akim Demaille <akim@epita.fr>
11249 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11250 removed.
11251 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11252 No need to remove the files before and after the each test, before
11253 each test and at the end of the suite is enough.
11254 Display only the children `times', not the shell's.
11255 If the test failed or was skipped, at-times is not available.
11257 2001-08-07 Akim Demaille <akim@epita.fr>
11259 Always produce testsuite.log, including when there are no
11260 failures. This helps getting information on skipped tests, and
11261 duration of the tests. Err, implement the latter btw.
11263 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
11264 Dump information on the first run of each test.
11265 (AT_CLEANUP): Create `at-times' containing the duration of the
11266 test group.
11268 2001-08-07 Akim Demaille <akim@epita.fr>
11270 The use of `dumpstat' revealed that `len' was used although it
11271 should not. m4_text_wrap was using it, but in the Autoconf world
11272 where it is legal. Hence (i) test M4sh in its own world, not
11273 Autoconf's, and (ii), ahem, fix the bug :)
11275 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11276 does not like `' instead of [].
11277 (AT_INIT): Forbid `^_?AT_'.
11278 And don't output such tokens.
11279 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11280 `script.as', and `autom4te.cache'.
11281 Remove `empty' and `macro' which are no longer used.
11282 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11283 * tests/m4sugar.at: Use it.
11284 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11286 2001-08-07 Akim Demaille <akim@epita.fr>
11288 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
11290 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
11292 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
11294 2001-08-04 Akim Demaille <akim@epita.fr>
11296 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
11297 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
11298 AC_TRY_LINK.
11299 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
11300 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
11301 (AC_F77_MAIN): Likewise.
11303 2001-08-04 Akim Demaille <akim@epita.fr>
11305 Don't rely on M4sugar outputting the patterns in files, since we
11306 might process the output _without_ running m4, hence without these
11307 files.
11309 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
11310 * bin/autom4te.in (@Request::includes): Remove, unused.
11311 (@Request::source): Rename as...
11312 (@Request::input): this.
11313 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
11314 (&handle_output): Fetch the patterns from the traces.
11315 `$forbidden' and `$allowed' are constant: use m//o.
11316 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
11317 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
11319 2001-08-04 Akim Demaille <akim@epita.fr>
11321 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
11322 autoconf', i.e., in addition to caching traces, cache the output.
11324 * bin/autom4te.in (Request::cache): Rename as...
11325 (Request::id): this.
11326 ($cache, $icache, $tcache, $ocache): New.
11327 (&handle_m4): Save M4 output in the cache instead of $tmp.
11328 (&handle_output): Adjust.
11329 (&up_to_date_p): Check that the output cache is up to date too.
11330 (top level): Run `&handle_m4' iff force or the cache is invalid.
11331 Run `&handle_output' if the output cache is more recent.
11333 2001-08-04 Akim Demaille <akim@epita.fr>
11335 * bin/autom4te.in ($force): New.
11336 (&parse_args, &print_usage): -f, --force is a new option.
11337 (&handle_output): CPP directives might have spaces after `#'.
11338 (&parse_args): The first file only can be frozen.
11340 2001-08-04 Akim Demaille <akim@epita.fr>
11342 Don't let autom4te compute the `include' traces several times:
11343 first check that the trace cache file is up to date, and then
11344 compare its timestamp with that of the output.
11346 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
11347 the preamble. Don't require 5.005 as Autom4te::General does it,
11348 and better yet (use `use', not `require'!).
11349 * lib/Autom4te/Struct.pm: Rename the last occurrences of
11350 Class::Struct as Autom4te::Struct.
11351 * lib/Autom4te/General.pm (File::stat): Use it.
11352 (&mtime): New, export it.
11353 * bin/autom4te.in: Use it.
11354 Declare `$req' is invalid if it is outdated.
11355 Don't declare it valid before saving it if something went wrong.
11357 2001-08-04 Akim Demaille <akim@epita.fr>
11359 Autom4te shall not encode Autoconf data, and preselecting traces
11360 must be proposed to the users.
11362 * bin/autom4te.in (@required_trace): Remove.
11363 (@preselect): New.
11364 (&parse_args, &print_usage): -p, --preselect is a new option.
11365 (&up_to_date_p): Adjust.
11366 * bin/autoconf.in: Preselect some Autoconf macros.
11368 2001-08-04 Akim Demaille <akim@epita.fr>
11370 * tests/tools.at (autoconf --trace: user macros): Check traces on
11371 macros invoked without arguments, and macros invoked with multiple
11372 lines arguments.
11374 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
11376 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
11377 arguments.
11379 2001-08-03 Akim Demaille <akim@epita.fr>
11381 * bin/autoconf.in ($@): Work around the usual sh bug.
11382 From Nicolas Joly.
11384 2001-08-03 Akim Demaille <akim@epita.fr>
11386 Clean up the handling of the M4 builtins tracing exception.
11388 * bin/autom4te.in (Request::request): Don't complete M4 builtins
11389 trace requests.
11390 (@m4_builtins): Rename as...
11391 (@m4_builtin): this.
11392 (%m4_builtin_alternate_name): New.
11393 (&parse_args): Complete the trace requests with alternate names.
11394 (&handle_traces): Hence no longer do it here.
11395 (&trace_requests): Remove, unused.
11397 2001-08-03 Akim Demaille <akim@epita.fr>
11399 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
11400 m4_if, and m4_wrap.
11402 2001-08-03 Akim Demaille <akim@epita.fr>
11404 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
11405 (m4_divert_pop): Dump the whole diversion stack when a diversion
11406 mismatch happens.
11407 * bin/autom4te.in (&handle_output): Remember of the first
11408 occurrence of a possibly undefined macro, not the last.
11409 Complain about the possibly undefined macros in the same order as
11410 the appear in the output.
11411 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
11412 * tests/tools.at (autoconf: forbidden tokens, basic)
11413 (autoconf: forbidden tokens, exceptions): No longer sort
11414 autoconf's stderr, as it is now deterministic.
11415 Check that `dnl' is caught.
11417 2001-08-01 Akim Demaille <akim@epita.fr>
11419 * configure.ac: Bump to 2.52c.
11421 2001-08-01 Akim Demaille <akim@epita.fr>
11423 Version 2.52b.

11431 2001-08-01 Akim Demaille <akim@epita.fr>

11434 `die'.
11435 (&END): New.
11436 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
11437 `END', as `Autom4te::General::END' will be triggered.
11438 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
11439 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

11874 cross-language link tests can be performed successfully.
11875 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
11876 after $LIBS, for consistency; this should be the general rule since
