12 2006-10-14 Stepan Kasal <kasal@ucw.cz>
14 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
15 looking for special shell characters.
16 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
17 macro defined by AS_VAR_PUSHDEF before passing it as a
18 parameter.
19 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
20 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):
21 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW, AC_CHECK_MEMBER):
22 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL):
23 (_AC_CHECK_HEADER_NEW, _AC_CHECK_HEADER_OLD, _AC_CHECK_HEADER_DIRENT):
24 Likewise.
25 * lib/autotest/general.m4 (AT_INIT): Quote parameters of
26 AS_VAR_* properly.

29 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
31 (Imported from Automake.)
32 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
33 which incorrectly sets the mode of an existing destination
34 directory. In some cases the unpatched install-sh could do the
35 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
36 system. We hope this is rare in practice, but it's clearly worth
37 fixing. Problem reported by Alex Unleashed in
38 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
39 Also, don't bother to check for -m bugs unless we're using -m;
40 suggested by Stepan Kasal.
42 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
44 Import this change from Automake:
46 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
47 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
48 is enabled by default with gnu and gnits strictness.
49 Report from Bruno Haible.
51 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
52 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
53 gnu and gnits modes.
55 Import this change from Config:
57 2006-09-20 Ben Elliston <bje@gnu.org>
58 * build-aux/config.sub (score, score-*): New.
60 Import this change from Gnulib:
62 2006-09-16 Karl Berry <karl@gnu.org>
63 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
64 to avoid sectioning errors.
66 Import these changes from Texinfo:
68 2006-10-04 Karl Berry <karl@gnu.org>
69 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
70 (\quoteexpand): rename to \rquoteexpand.
71 (\codequoteleft): new def, to look for @set codequotebacktick.
72 (\lquoteexpand, \quoteexpand): new defs.
73 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
74 (\code): must use new \...Char values, since now ` is active.
76 2006-08-26 Karl Berry <karl@gnu.org>
77 * build-aux/texinfo.tex (\textdegree): New command.
79 2006-08-12 Karl Berry <karl@gnu.org>
80 * build-aux/texinfo.tex (error \box0): smaller font.
82 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
84 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
86 2006-10-13 Stepan Kasal <kasal@ucw.cz>
88 * doc/autoconf.texi (Autoheader Macros): Warn that the text
89 added to the template can get mangled.
91 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
93 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
94 include the default headers, and redefine obstack_chunk_alloc
95 and obstack_chunk_free. Fixes false failure with glibc.
97 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
99 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
100 for backward compatibility with Libtool 1.5.22. Problem reported
101 by Ralf Wildenhues.
103 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
105 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
106 AC_PROG_CC.
107 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
109 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
111 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
112 the NonStop platform.
113 * doc/autoconf.texi (Posix Variants): Likewise.
114 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
116 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
117 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
118 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
119 Use a better substitute, by inspecting the output of "ls"
120 rather than just using ":".
121 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
122 rather than AS_EXECUTABLE_P, since we needn't worry about
123 non-regular files here.
125 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
126 due to configuration hassles with this. See Tonya Underwood's report
127 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
128 * doc/autoconf.texi (Special Shell Variables): Likewise.
130 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
131 Stepan Kasal <kasal@ucw.cz>
133 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
134 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
136 2006-10-11 Stepan Kasal <kasal@ucw.cz>
138 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
139 initialization which is not inherited through the environment
140 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
141 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
143 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
145 * doc/autoconf.texi (Limitations of Usual Tools): Describe
146 problems with mkdir -p -m.
148 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
150 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
151 comment about ac_cpp_err; it was incorrect, and anyway
152 ac_cpp_err is being removed below.
153 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
154 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
155 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
156 nobody uses it.
157 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
158 with werror_flag and conftest.err and so forth. This is more
159 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
160 and anyway the user shouldn't normally want to see this gorp logged.
161 Problem reported by Ralf Wildenhues.
162 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
163 empty, not 'no', since the rest of the code uses 'test -z'.
165 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
167 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
168 Use a single call to AC_DO_TOKENS rather than multiple, for
169 efficiency.
170 (_AC_LINK_IFELSE): Test that resulting file is executable.
171 Problem reported by mwoehlke in
172 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
174 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
175 than creating a file to use with test -x; this is much faster.
177 2006-10-02 Bruno Haible <bruno@clisp.org>
179 * lib/autom4te.in (Automake-preselections): Add
180 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
182 2006-09-27 Stepan Kasal <kasal@ucw.cz>
184 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
185 standard error, `experr' should be used, not `expout'.
187 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
189 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
190 fseeko testing program twice; just use the earlier result.
191 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
192 Set cache var to 'unknown' (not 'no') if leaving the macro unset
193 still doesn't let the program compile.
194 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
195 failed.
197 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
198 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
199 include it, without including anything else.
200 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
201 expressions.
202 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
204 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
206 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
207 `error.h', and include it, for a `error_at_line' prototype.
208 Use a nonempty format string in the link test.
209 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
210 for a declaration of wait3.
212 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
214 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
215 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
216 can apply to constants too, and that it checks for macro defns.
217 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
218 and simply cast the identifier to void. This handles structure
219 values. Problem reported by Ralf Wildenhues.
220 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
222 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
224 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
225 structure, and function symbols.

241 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): Avoid `gcc -Wall'
242 warnings (uninitialized value).
243 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
244 present.
245 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add
246 parentheses.
247 (AC_STRUCT_TM): Likewise, avoid unused variables.

275 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
276 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
277 --error-output, to avoid warnings with M4 2.0.
279 2006-09-19 Stepan Kasal <kasal@ucw.cz>
281 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be
282 consistent with _AH_CHECK_FUNCS and _AH_CHECK_HEADERS.
283 * lib/autoconf/headers.m4 (AH_CHECK_HEADERS_DIRENT): Likewise.
285 2006-09-15 Stepan Kasal <kasal@ucw.cz>

290 2006-09-14 Stepan Kasal <kasal@ucw.cz>
292 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
293 mistaken comment: the path has to be relative; do not use
294 the path at runtime.
296 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
298 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

302 for both changes.
303 * doc/autoconf.texi (Setting Output Variables): Fix example to
304 not show `--silent' being passed to a `configure' re-run.
306 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
308 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
309 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
310 for the existence of the directory at configure-time. That's
311 too late, anyway. Problem reported by Stefan Seefeld.
313 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
314 7.1.4 /usr/bin/posix/sh described by Tim Rice in
315 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
317 2006-09-11 Stepan Kasal <kasal@ucw.cz>
319 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
320 works with GNU M4 1.4.3 again; make the normalized form
321 match the current m4 message; fix the description.
322 * test/tools.at (autom4te cache): Adapt to the change.
324 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
326 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
327 to catch glibc bug 2821
328 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
330 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
331 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
332 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
333 assume C89.
335 2006-09-08 Stepan Kasal <kasal@ucw.cz>
337 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the
338 preselections ...

351 by Dries Kimpe.
353 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
355 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
356 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
357 accept files with extension `.f'. For consistency, also prefer
358 xlf over f77.
359 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
360 from last patch.

377 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
379 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
380 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
381 except the first two arguments are reversed.
382 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
383 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
384 caches nor outputs a diagnostic. Suggested by Bruno Haible.
385 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
386 equivalent to the old AC_COMPUTE_INT.
387 (AC_COMPUTE_INT): No longer caches or reports. New signature.
388 All uses changed to AC_CACHE_CHECK_INT.
389 * tests/base.at (AC_CACHE_CHECK_INT): New test.

394 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
395 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
396 programs should use their Gnulib counterparts.
397 * doc/autoconf.texi (Particular Functions): Likewise.
398 (Macro Names, testsuite Invocation): Replace uses of these
399 obsolete macros with uses of non-obsolete macros.
401 2006-08-29 Eric Blake <ebb9@byu.net>

409 mistakenly swapped on 2006-08-15.
411 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>

418 file created by the PGI compiler.
420 2006-08-25 Noah Misch <noah@cs.caltech.edu>

423 simplify the code.
425 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
427 Fix Lex library problem reported to us by Julio Garvia.
428 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
429 for the default, which the user can override.
430 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
431 deal with LEXLIB.
432 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
433 didn't work if some values were cached but not others. Test for
434 broken lex libraries like native ia64-hp-hpux11.22; see
435 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
436 work around the problem by preferring an empty LEXLIB to -lfl or
437 -ll. Let the user set LEXLIB='' to indicate no library needed.
439 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
440 * README: Likewise.
441 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
443 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>

465 (autom4te-update): Rewrite with a loop. Get from gnulib, not automake.
466 Fail if there's an error.
467 * Makefile.cfg (move_if_change): Remove.

548 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
549 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
550 Bill Northcott in
551 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.

559 longer supported by Sun.
561 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
563 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
564 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
565 -Wundef -Werror". Problem reported by David Fang in
566 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
567 * doc/autoconf.texi (Header Templates, Default Includes):

583 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
584 this.
586 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
588 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
589 problems with arg script text that doesn't end in newline, and
590 with '-e a...'. Problems reported by Ralf Wildenhues.
592 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
594 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

606 settings. Report by Bruno Haible.
608 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
610 Fix test suite failures reported by Pierre in
611 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
612 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
613 the compiler created a file "b.out" when it didn't create anything
614 at all.
615 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
616 Discard stderr too, when invoking the test script.

626 less skeptical about "volatile", after discussion with
627 Bruno Haible on bug-gnulib.

629 leading white space from text. From Bruno Haible.
631 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
633 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
634 compiler complains about it, even if things works after the
635 complaint. Problem reported by Peter O'Gorman.
637 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
638 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
639 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
641 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
643 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
644 after -R regardless of host. Patrick Welche reports that this
645 fixes things on NetBSD 3.99.
647 * NEWS: Recommend M4 1.4.5.
648 * README: Likewise.
649 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

653 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
655 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
656 under AC_C_VOLATILE.
657 (Volatile Objects): Be a little less skeptical about what
658 "volatile" means. Derived from thoughts by Ben Pfaff in
659 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
661 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
663 * doc/autoconf.texi: Fix some typos.
665 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
667 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
668 more globally, since the 2006-06-30 patch didn't suffice. Problem
669 reported by Keith Marshall. Also, don't bother with builddir2,
670 since it shouldn't be needed any more.
672 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
674 * doc/autoconf.texi (Generic compiler characteristics):
675 Document AC_COMPUTE_INT. Fix wrong statements on Default
676 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
678 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
679 (_AC_COMPUTE_INT): Add obsoletion warnings.

685 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
687 * doc/autoconf.texi (Volatile Objects): New section.
689 * NEWS: Document previous change.
691 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
693 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
694 Require that long long int be at least 64 bits wide. C99 requires
695 this and enough programs depend on it so we should check for it.
696 Bruno Haible reports in
697 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
698 that long long int is 32 bits wide with some nonstandard compilers.
699 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
701 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
703 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
704 to a nonexistent file, so that we don't have to worry about
705 a local site configuration that doesn't use /usr/local.
706 Problem reported by Keith Marshall in
707 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
709 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
711 * doc/autoconf.texi: Be more consistent about using @acronym with
712 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
713 quite right (it talked about "OSF/Tru64", even though the
714 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
715 and it even mentioned "OSF 4"!) and at this point there's little
716 reason to talk about OSF any more, since it died in 1994.
717 (Specific Compiler Characteristics): Simplify example of
718 negative-size array.
719 (File Descriptors): Reorder to make the text flow better.
720 Remove joke about "appreciate the various levels"; I didn't get it.
721 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
722 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
723 (File Descriptors, Limitations of Usual Tools):
724 Tone down the advice against renaming or removing open files.
725 (Limitations of Usual Tools): Add a new section, on 'rm'.
727 2006-06-26 Stepan Kasal <kasal@ucw.cz>
729 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
730 -lXt in LIBS, idea from Karsten Hopp; this was due since
731 this change:
733 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
734 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
735 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
736 (which belong to Xt, not X itself). See Debian bug 327655.
738 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
740 * configure.ac (AC_INIT): Bump to 2.60a.
741 * NEWS: Update.
743 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
745 Version 2.60.
747 * configure.ac, NEWS: Update.
749 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
751 * config/texinfo.tex: Sync from upstream.
753 * bin/autom4te.in (handle_traces): Transform the `@S|@'
754 quadrigraph correctly in traces.
756 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
757 Fix typos.
759 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
760 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
761 not defined.
762 * doc/autoconf.texi (Changed Directory Variables): New node,
763 to document the whole `datarootdir' business a bit better.
764 * NEWS: Update.
765 * tests/torture.at (datarootdir workaround): Extend test.
766 Prompted by report by Alexandre Julliard.
768 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
770 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
771 when using default mode of IBM C 6 for AIX. Problem and two-line
772 fix reported by Larry Jones.
774 2006-06-22 Alexandre Julliard <julliard@winehq.org>
776 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
777 about literal '${datarootdir}' if a definition is found in the
778 output file.
780 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
782 * NEWS: Use "M4" rather than "m4" when appropriate.
783 Problem reported by Eric Blake.
784 * doc/autoconf.texi: Likewise.
785 Use @acronym around BSD, GCC, and GNU when appropriate.
786 (Why GNU M4): Renamed from "Why GNU m4".
787 (Redefined M4 Macros): Mention that Posix
788 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
789 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
790 to int.
792 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
794 * bin/autom4te.in (handle_output): Do not forbid the empty
795 pattern.
796 * tests/tools.at (autoconf: the empty token): New test.
798 2006-06-20 Stepan Kasal <kasal@ucw.cz>
800 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
801 calls, so that we do not care whether they are LIFO or FIFO;
802 in the m4_wrap, do not check which diversion is the topmost
803 one, just check that the stack is balanced at the end.
804 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
805 base diversion forever--pop the previous diversion before
806 opening the new one; consequently, remove the m4_wrap call.
807 * lib/autotest/general.m4 (AT_INIT): Likewise.
808 * tests/m4sugar.at: Do not use
809 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
811 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
812 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
814 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
815 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
816 Rework example of m4wrap token-pasting trouble so that it doesn't
817 care whether it's LIFO or FIFO.
818 Fix some "contrary to"s that are awkward in English.
820 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
822 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
823 to `yes' instead of `int$1_t' if the type is found, for more
824 consistent configure output (where $1 is the number of bits).
825 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
826 Suggested by Bruno Haible.
828 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
829 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
830 with system headers. Report by Bruno Haible.
832 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
834 * config/config.guess, config/config.sub: Sync from upstream.
836 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
837 in order to avoid picking up an older installed frozen m4sh.m4f.
838 Besides an outdated shell startup, this could have been created
839 by an earlier M4 version with incompatible frozen file format.
841 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
843 * README: Recommend m4 1.4.4 instead of 1.4.3..
844 * doc/autoconf.texi: Likewise.
845 (Special Chars in Names): Say that $(.FOO) is portable, as
846 suggested by Stepan Kasal.
847 (Installation Directory Variables, Build Directories):
848 (Automatic Remaking, Subdirectories, Fortran Compiler):
849 (Making testsuite Scripts, Defining Directories):
850 Quote variable usages better.
851 (Making testsuite Scripts): Add clean-local rule to makefile
852 snippet, by Eric Blake.
853 (Installation Directory Variables): Fix table item font.
854 Reword slightly to clarify. Generalize advice about
855 not using special characters to include all file-related
856 vars, not just VPATH.
857 (Special Chars in Variables): Warn about special characters in
858 $(srcdir) too.
859 (Assignments): Clarify default-value example as suggested by
860 Ralf Wildenhues in
861 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
862 (Special Shell Variables): Note leading ./ or ../, as suggested
863 by Eric Blake.
864 (Limitations of Builtins): Under cd, warn about CDPATH.
865 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
866 Ralf Wildenhues.
868 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
870 * doc/autoconf.texi (Configuration Actions): Remove duplicate
871 `@var', for texi2html.
872 (Systemology): Some more word wrapping, for DVI output.
873 (autom4te Invocation): The short option for `--melt' is `-M',
874 not `-m'.
876 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
878 * doc/autoconf.texi: More formatting and English tweaks,
879 many suggested by Ralf Wildenhues.
880 Reword to avoid "@code{...}'s" and the like, since it's ugly
881 with Emacs info mode. discontents -> woes.
882 Put a few "will"s back. time stamp -> timestamp.
883 side-effect -> side effect.
885 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
887 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
888 Warn about $@ not persisting. Problem reported by Julien Danjou in
889 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
890 (Special Chars in Names): Renamed from Leading _ in Macro Names.
891 Mention other special chars, too.
893 2006-06-14 Eric Blake <ebb9@byu.net>
895 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
897 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
899 * doc/autoconf.texi: Some systematic minor improvements, as
900 follows. Use "makefile" when talking about makefiles
901 generally (which might be named "makefile" or "Makefile" or even
902 "foo.mk"), "Makefile" when talking about a specific makefile
903 called "Makefile". This unclutters the text from weird quotes
904 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
905 values" rather than "@var{foo}s" and similar constructs containing
906 "}s". Use "Make rules" rather than "Makefile rules". Minor
907 English-language improvements. Change the prefix "sub-" to "sub"
908 and "re-" to "re".
909 Put blank lines around examples more consistently.
910 Avoid "rather" and "very" as intensifiers.
911 Avoid "will" as an auxiliary.
912 (Limitations of Make): Split this node into....
913 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
914 (Leading _ in Macro Names, Backslash-Newline-Newline):
915 (Backslash-Newline Comments, Long Lines in Makefiles):
916 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
917 (obj/ and Make, make -k Status, VPATH and Make):
918 (VPATH and Double-colon, $< in Explicit Rules):
919 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
920 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
921 New nodes, resulting from splitup of Limitations of Make.
922 All cross-references changed. Raise the top node from
923 a section to a chapter, and all subnodes accordingly.
924 Redo the introductory wording to match the new organization.
925 (Installation Directory Variables): Use an example that is
926 closer to what Autoconf actually does. Mention that VPATH's
927 value should not contain metacharacters or white space.
928 (Fortran Compiler): Fix a VPATH bug in an example.
929 (Leading _ in Macro Names): Mention that this problem is no longer
930 of practical concern.
931 (VPATH and Make): Reword the advice to make it clearer
932 that Autoconf and Automake support VPATH in non-GNU make, but
933 many packages have bugs in this area.
934 ($< in Explicit Rules): Refer to Build Directories rather
935 than using a (non-VPATH-safe) example.
936 (Automatic Rule Rewriting): Mention the sort of disaster that
937 can ensue with Solaris-style rule rewriting with VPATH.
939 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
941 * doc/install.texi (Compilers and Options): Weaken the
942 suggestion to use GNU make for VPATH builds.
944 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
945 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
947 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
948 in regular expression.
950 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
952 * doc/autoconf.texi (Installation Directory Variables):
953 Drop extra @samp from `@table @samp' item.
954 (Limitations of Usual Tools): Comment fix.
955 Do not nest @samp just to point to other table items.
956 (Writing testsuite.at) <AT_CHECK>: The second argument to
957 `@dvar' is already @samp'ed.
958 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
959 do not use @var in the second argument.
961 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
963 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
964 $as_shell.exe too. Problem reported by Andreas Buening in
965 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
967 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
969 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
970 `unused variable' compiler warning, for `-Wall -Werror'.
971 Reported by Jaap Haitsma in
972 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
974 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
976 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
977 case the compiler dumps core. Problem reported for
978 OpenServer 5.0.7 by Tim Rice in
979 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
980 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
981 Likewise.
983 2006-06-06 Tim Rice <tim@multitalents.net>.
985 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
986 "ERROR" only shows up in "make check" output if there is an
987 error.
989 2006-06-06 Eric Blake <ebb9@byu.net>
991 * tests/tools.at (automatically allowed tokens): Fix typo.
993 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
995 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
997 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
998 typically overflows on x86 CPUs, even though the C standard
999 requires otherwise.
1001 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1003 * configure.ac (AC_INIT): Bump to 2.59e.
1004 * NEWS: Update.
1006 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1008 Version 2.59d.
1010 * config/texinfo.tex: Sync from upstream.
1012 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1013 seen, invoke libtoolize with `--ltdl' argument.
1014 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1015 * NEWS: Update.
1016 Suggested by Eric Blake.
1018 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1020 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1021 reported by Ralf Wildenhues.
1022 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
1024 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1026 * THANKS: Update.
1028 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1030 * doc/autoconf.texi: Modernize some of the references to Solaris.
1032 2006-06-05 Stepan Kasal <kasal@ucw.cz>
1034 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
1035 message issued by AC_REQUIRE.
1036 * tests/m4sugar.at: Check m4_require's error message.
1037 * tests/base.at: Check AC_REQUIRE's error message.
1038 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1039 to...
1040 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1041 AT_CHECK_M4.
1042 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1043 `expout' as the last parameter.
1044 * tests/tools.at: Adapt to the above change.
1046 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1048 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1049 information about race-free implementations of mkdir.
1051 2006-06-04 Eric Blake <ebb9@byu.net>
1053 * bin/autoreconf.in (help): Document M4 environment variable.
1054 * bin/autoconf.as (Usage): Likewise.
1055 * bin/autom4te.in (help): Likewise.
1056 * doc/autoconf.texi (autom4te Invocation): Likewise.
1058 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1060 * NEWS: GNU make now recommended for VPATH builds.
1061 Mention that some macros are now documented to be obsolescent.
1062 * doc/autoconf.texi:
1063 Prefer "current" to "modern" to describe
1064 currently-used (albeit perhaps old-fashioned) hosts.
1065 Mention which ancient features no longer need to be worried about.
1066 setgid -> set-group-ID
1067 setuid -> set-user-ID (these are the Posix terms)
1068 Fix some misuses of "only".
1069 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1070 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1071 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1072 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1073 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1074 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1075 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1076 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1077 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1078 Mention that these macros are obsolescent.
1079 (Installation Directory Variables): shall -> should
1080 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1081 Mention that it's now safe to use 3 and 4.
1082 (Limitations of Usual Tools): cp -r is now specified by Posix.
1083 Omit longwinded and obsolescent discussion of cp -f.
1084 Modernize discussion of expr, ls.
1085 (Limitations of Make): Modernize discussion of VPATH builds.
1086 Mention $? as a workaround in some cases.
1087 * doc/install.texi (Basic Installation):
1088 Mention "./configure; make; make install" first. Be more
1089 specific about why this file is generic. Remove unnecessary
1090 parens. Remove misleading "only". Remove obsolete advice
1091 about csh. Don't say "configure" takes awhile; say it
1092 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1093 and CC=c99 rather than CC=c89, as these are blessed by current
1094 Posix. Recommend GNU make if doing a VPATH build.
1096 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1098 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1099 examples involving shell prompts.
1101 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1102 and Paul Eggert <eggert@cs.ucla.edu>
1104 * doc/autoconf.texi (Here-Documents): Add details about the
1105 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1106 use "here-documents" instead of "here documents".
1108 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1110 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1112 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1114 * doc/autoconf.texi (File System Conventions): Warn about ":"
1115 anywhere in directory names.
1117 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1119 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1120 about quoting the case statement, just in case.
1121 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1122 was fixed in ksh93g; reported by Ralf Wildenhues.
1124 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1126 * doc/autoconf.texi (System Services): Do not document
1127 overriding EXEEXT via ac_cv_exeext=ext.
1128 (Particular Programs) <AC_PROG_MKDIR_P>:
1129 Document that ${MKDIR_P} understands --.
1130 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1131 comment.
1133 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1135 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1136 argument with leading hyphen. Problem reported by Paul Eggert.
1138 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1140 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1141 about quoting ac_try: quote all of it, if any of it seems suspicious.
1142 This means we don't have to worry about ${ or sed any more.
1143 Also, double-quote the case statement, to work around misuses via
1144 underquoting as reported by Ralf Wildenhues in
1145 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1146 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1147 undocumented and dangerous macro.
1148 Problem reported by Ralf Wildenhues in
1149 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1151 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1153 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1154 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1155 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1157 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1159 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1160 since evidently some packages rely on the old, broken behavior.
1161 Problem reported by Ralf Wildenhues in
1162 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1163 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1164 pre-2006-05-26 definitions, but leave in the comments that
1165 these macros are dangerous and should not be used.
1166 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1167 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1168 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1169 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1170 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1172 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1174 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1175 the use of 'tr', since this is our only use of 'tr'.
1177 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1178 and Paul Eggert <eggert@cs.ucla.edu>
1180 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1181 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1183 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1185 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1186 the output file in the `${datarootdir}' test.
1188 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1189 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1191 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1192 mention of `datarootdir' in the input file(s), but literal
1193 `${datarootdir}' in the output file, and we haven't warned yet,
1194 then warn as well: the user may have (erroneously) used
1195 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1196 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1197 * tests/torture.at (datarootdir workaround): Extend this test.
1198 * NEWS: Update.
1200 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1201 and Paul Eggert <eggert@cs.ucla.edu>
1203 * doc/autoconf.texi (autoheader Invocation): The first argument to
1204 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1205 alternatives and clear up the language a bit.
1207 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1209 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1210 ac_config_guess, ac_config_sub, ac_configure.
1211 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1212 Fix typo that prevented an unnecessary space from being removed.
1213 Problems reported by Ralf Wildenhues in:
1214 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1216 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1218 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1219 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
1220 Don't use the term "thread-safe" to talk about mkdir race
1221 conditions, since the problem is more a process than a thread
1222 issue. Problem reported by Stepan Kasal in:
1223 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
1224 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
1225 the test for 'install' more closely. Look at MKDIR_P first.
1226 Look in the PATH, and at /opt/sfw/bin.
1227 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1228 Don't bother to try mkdir -p, since we already check mkdir --version;
1229 just look at the version number. (There's no easy way to check
1230 for race-free implementations.)
1231 * tests/tools.at (autoconf: subdirectories): Adjust to above
1232 changes, since MKDIR_P now might end in "/mkdir -p".
1234 * doc/autoconf.texi (autoheader Invocation): Mention that the
1235 first arg of AC_DEFINE_UNQUOTED must be a literal.
1236 Problem reported by Ben Pfaff in
1237 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1239 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1240 * doc/autoconf.texi (Special Chars in Variables): New section.
1241 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1242 (Installation Directory Variables): Quote $(datadir) better.
1243 (Limitations of Builtins): Describe some of eval's trickiness.
1245 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1246 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1247 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1248 in front of every arg, not just trailing args. Quote apostrophes.
1249 (_AC_EVAL_ECHO): New macro.
1250 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1251 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1252 removed.
1253 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1254 exposed by quoting of eval argument. Put the command on line line
1255 so it logs better.
1256 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1257 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1258 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1259 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1260 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1261 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1262 Use eval more safely.
1263 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1264 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1265 to be replaced.
1266 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1267 lines, exposed by quoting of eval argument.
1269 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1270 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1272 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1273 initialization of `ac_cv_exeext', do not override it if it was
1274 already set, unless it was set to `no', for compatibility with
1275 Autoconf-2.13, and comment this.
1276 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1277 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1278 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1279 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1280 Document that this test may be overridden by setting
1281 `ac_cv_exeext'.
1283 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1285 Revert these two patches:
1287 2006-04-06 Eric Blake <ebb9@byu.net>
1288 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1289 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1290 2006-04-01.
1292 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1293 Clean up _AC_COMPILER_EXEEXT* macros.
1294 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1295 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1296 ac_file to the name of the default output file and call
1297 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1298 initial `rm' of the candidate files...
1299 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1300 the same list in subsequent `rm' calls, and for the temporary
1301 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1302 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1303 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1304 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1305 no longer needed) by libtool. Make it a cache check.
1306 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1307 copied here by mistake.
1308 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1309 _AC_COMPILER_EXEEXT.
1310 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1311 _AC_COMPILER_OBJEXT directly.
1312 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1314 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1316 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1317 Fix description of how the buggy `sed' works.
1319 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1321 Sync from Automake:
1323 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1324 ENOLCK. Only mention `make -j' when applicable. Only raise
1325 fatal errors when `make -j' is involved. Improve error message.
1327 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1329 * doc/autoconf.texi (Here-Documents): We now know more about
1330 the variable expansion in here documents bug.
1331 Thanks to Tim Rice and Stepan Kasal.
1333 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1334 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1336 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1338 * tests/autotest.at (Multiline command from M4 expansion):
1339 No failure to be expected if the shell quotes newlines in
1340 commands in the `set -x' output. Report by Tim Rice.
1341 * THANKS: Update.
1343 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1345 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1346 expansion in the here-documents used by config.status, as that
1347 runs afoul of the Korn shell version M-12/28/93d bug described in
1348 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1349 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1350 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1352 2006-05-23 Jim Meyering <jim@meyering.net>
1354 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1355 Fix typo introduced with 2006-04-02 change. It reversed the sense
1356 of the test.
1358 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1360 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1361 ac_dB slightly, to save bytes in the script.
1362 Max out at 50 lines, rather than 96; this is more likely
1363 (though not guaranteed) to avoid obscure 'sed' failures.
1365 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1367 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
1368 `tr -d -' as bad option argument. Work around this by deleting
1369 an unrelated character.
1370 Report by Tim Rice <tim@multitalents.net>.
1372 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
1373 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1374 Stepan Kasal <kasal@ucw.cz>
1376 * doc/autoconf.texi (Particular Programs): Do not promise that
1377 we always prefer the GNU version of the program, and that we
1378 search according to PATH; both rules can have exceptions.
1379 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
1380 AC_PROG_SED. Move descriptions of limitations
1381 to the Limitations of Usual Tools section.
1382 (Limitations of Usual Tools) <sed>: Mention script length
1383 limitations with Solaris /usr/ucb/sed.
1384 <grep>: Fix wording for empty alternative. Mention that -c and
1385 -l should not be combined, and that -E and -F should not be
1386 combined.
1388 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1389 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1391 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
1392 limits in Solaris 8 /usr/ucb/sed by testing a long script.
1394 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1396 * doc/autoconf.texi (Defining Symbols): Literal parameter of
1397 AC_DEFINE is now passed to m4_pattern_allow.
1398 * NEWS: Mention that; likewise for AC_SUBST.
1399 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
1400 the parameter to m4_pattern_allow.
1401 * tests/tools.at: Add a check for that.
1403 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1405 * lib/autoconf/status.m4: Fix typos.
1407 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1409 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1410 only the files that this macro generates.
1412 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1414 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1415 the HP-UX sed limitation of 99 commands, labels do not count.
1416 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1417 in the comment.
1418 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1420 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1422 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1423 Import the following fix from coreutils:
1425 2006-01-13 Jim Meyering <jim@meyering.net>
1427 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1428 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1429 not double-quote uses of that variable, to accommodate the rare
1430 case in which getmntent is available in none of the libraries
1431 checked. This happens at least on FreeBSD 5.0.
1433 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1435 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
1436 ac_config_guess, ac_config_sub, and ac_configure, since evidently
1437 some other programs unwisely rely on these undocumented vars.
1438 But put in warning comments about them.
1439 Problem reported by Ralf Wildenhues in
1440 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
1441 * NEWS: Document that these variables are intended to go away.
1443 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1445 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
1446 and set the language to C++ (analogous to the equivalent Fortran
1447 tests).
1449 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
1450 * doc/autoconf.texi (C++ Compiler): Document it.
1451 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
1452 * NEWS: Update.
1454 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1456 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
1457 that caused config.status to generate 100-command sed scripts; the
1458 portable limit is 99.
1460 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1462 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
1463 variable `ac_d' instead of `d' to avoid infringing namespace.
1464 Report by Ralf Menzel.
1466 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
1468 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
1469 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
1470 * tests/tools.at (autoconf: subdirectories): New test, taken from
1471 the corresponding problem report by Ralf Wildenhues in:
1472 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
1474 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
1475 Quote some uses of shell variables if they might suffer unexpected
1476 globbing. This doesn't fix all instances of quoting problems that
1477 I found, just the easy ones that look safe.
1478 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
1479 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
1480 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
1481 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
1482 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
1483 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
1484 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
1485 Likewise.
1486 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
1487 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
1489 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1491 * bin/autoreconf.in ($help): Reword according to the manual.
1492 Suggested by Olly Betts.
1494 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
1495 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1497 * bin/autoreconf.in: Pass the directory argument to
1498 `require_configure_ac'. Fix comment.
1499 * tests/torture.at (Configuring subdirectories): Expose this.
1500 Reported by Olly Betts.
1502 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1504 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
1505 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
1506 Automake as follows:
1508 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
1509 `$configure_in' instead of `configure.in', to preserve
1510 directory component.
1512 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1514 * config/config.guess, config/config.sub, config/texinfo.tex,
1515 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
1517 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1519 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
1520 test for C99 conformance; (bool) 0.5 is an integer constant
1521 expression, but (bool) -0.5 is not. Problem reported by Fedor
1522 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
1524 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1526 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
1527 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
1528 Warn about obsolete install-sh files. Remove stray sentence
1529 fragment and fix cross reference.
1530 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
1531 install -d; this undoes the 2006-05-10 change.
1532 (MKDIR_P): Mark with AN_MAKEVAR.
1533 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
1534 that we don't require $INSTALL to be thread-safe. Move comments
1535 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
1536 of AC_PROG_INSTALL. Output a message saying that we're checking
1537 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
1538 MKDIR_P instead of AC_SUBST.
1539 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
1540 Special magic for MKDIR_P, too.
1541 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
1542 a dnl.
1543 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
1545 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1547 Sync from Automake, as follows:
1549 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1550 * config/install-sh: Initialize IFS, so field splitting isn't
1551 turned off later.
1552 * config/mkinstalldirs: Likewise.
1553 * config/missing: Remove superfluous quotes. Replace all uses of
1554 `[' by `test', for consistency, and for..
1555 * config/missing (sed_minuso, sed_output): New variables.
1556 (autom4te, help2man, makeinfo): Use them. Unifies detection of
1557 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
1558 Fixes `missing' to detect `--output' for help2man. Fixes
1559 PR automake/483. Report by Dennis J. Linse.
1560 (autom4te): Document in `missing --help'.
1562 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1564 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1565 * config/install-sh: Don't use 'path' to talk about file names,
1566 as per GNU coding standards. Close a race condition reported by Ralf
1567 Wildenhues and Stepan Kasal. There is still a race condition
1568 on hosts that predate Posix 1003.1-1992, but we can't help this.
1569 Don't mishandle weird characters like space on pre-Posix hosts.
1570 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1571 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1572 AC_PROG_MKDIR_P from AS_MKDIR_P.
1573 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1574 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1575 earlier editions are not (including Automake 1.8.3).
1576 Do not suggest mkinstalldirs for thread-safety.
1577 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1578 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1579 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1580 presence of special characters and race conditions.
1581 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
1582 in Autoconf's name space.
1584 2006-05-10 Bruno Haible <bruno@clisp.org>
1585 and Paul Eggert <eggert@cs.ucla.edu>
1587 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
1588 from Automake with minor changes.
1589 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
1591 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1593 * config/install-sh: Update to Automake CVS version, as follows:
1594 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1595 * lib/install-sh: Simplify the expr implementation of dirname.
1596 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
1597 * lib/install-sh: Handle --, and diagnose unknown options.
1599 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1601 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
1602 `./autom4te' to create `./testsuite', since the `all' target
1603 will ensure its presence, but `installcheck' should not create
1604 the uninstalled wrappers.
1606 * tests/torture.at (Unusual Automake input files): Skip if we
1607 detect automake < 1.8.
1609 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1611 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
1612 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
1613 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
1614 * NEWS: Update.
1616 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1618 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1619 munge (multiple) white space and other oddities.
1620 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1621 single quotes in variable assignment.
1622 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1623 and similar failures by adding multiple spaces, tabs, and other
1624 special characters.
1625 Report and different test suggested by Francesco Romani
1626 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1628 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1629 single quotes, we only need to search for single quotes; this
1630 both simplifies the search pattern, and makes us less
1631 susceptible to `echo' variations for arguments not containing
1632 single quotes.
1633 (_AC_ARG_VAR_VALIDATE): Likewise.
1635 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1637 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1638 `$*' and IFS concatenation issue with traditional shells and
1639 bash-2.04. Report by Seanster@Seanster.com.
1641 2006-05-03 Bruno Haible <bruno@clisp.org>
1643 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1644 precisely which Mac OS X versions have the od problem.
1646 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1648 * doc/autoconf.texi: Use @option systematically.
1650 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1651 and Bruno Haible <bruno@clisp.org>
1653 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1654 about 'od'.
1655 (Integer Overflow): Mention the special case of integer division
1656 overflow.
1658 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1660 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1661 traditional shells like the Solaris one that do not use the
1662 first IFS character for assembling `$*'.
1663 Prompted by a related report from autoconf_bug@nro.ca.
1665 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1666 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1668 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1669 Mention more problems with the -e option.
1671 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1673 * NEWS: Typo.
1674 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1676 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1677 in URLs to improve DVI formatted output (requires texinfo 4.6).
1678 (System Services, Systemology, Shellology): Likewise.
1679 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1680 output.
1682 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1683 continuous text.
1684 (Runtime): Fix macro argument names to match description:
1685 `action-if-found' -> `action-if-true' and similarly.
1686 (Obsolete Macros): Likewise.
1687 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1688 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1689 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1691 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1693 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1695 * ChangeLog: Typo.
1696 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1697 DVI output.

1708 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
1709 (Integer Overflow, Null Pointers, Buffer Overruns):
1710 (Floating Point Portability, Exiting Portably): New sections.
1711 (Writing Test Programs): Fix some langauge. Recommend exiting
1712 with status 1, not merely nonzero. Clarify exit declaration.
1713 (Run Time): Move C exit status stuff to new Exiting Portably section.
1714 (Systemology): Mention Posix and levenez. Update v7 reference.
1715 (Portable Shell): Mention the Posix shell.
1717 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1719 * bin/autoconf.as (me): Replace by as_me.
1721 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1723 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1724 since as_me isn't set yet.
1726 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1728 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1729 a few minor bugs in this area.
1731 * doc/autoconf.texi (Programming in M4sh): Comment out the
1732 documentation of AS_BASENAME, for now.
1733 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1734 (Limitations of Builtins) <basename>: Do not refer to
1735 AS_BASENAME.
1736 * bin/autoconf.as (me): Don't use AS_BASENAME.
1737 (dir): Remove the unused variable.
1738 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
1739 AS_DETECT_REQUIRED. All uses changed.

1741 All uses changed.
1742 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

1745 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1746 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
1747 (_AS_DIRNAME_PREPARE): Likewise.
1748 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
1749 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
1750 (AS_DIRNAME): Use "dirname --".
1752 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1754 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1755 of "run time" and "run-time" changed to "runtime", for consistency.

1762 with more accuracy and detail.
1764 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1766 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1767 Archive is not officially `GNU' any more. Update URL.
1768 (Defining Directories): Likewise
1769 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1771 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1773 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1774 newline from the `trap' code to finish `config.log'; the NetBSD
1775 /bin/sh resets the exit status after an empty command, as
1776 documented in doc/autoconf.texi.
1777 Reported by Dalibor Topic <robilad@kaffe.org>.
1779 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1781 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1782 Suggested by Bruno Haible.
1784 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1786 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1787 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1788 Instead, just list the shells that we know work.
1789 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1790 changed. Be more cautious about the _cv_ variable.
1791 * tests/tools.at (Syntax of the shell scripts): Check the
1792 _cv_ variable once, at first, to avoid an internal autoconf error
1793 when sh -n does not work.
1795 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1797 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1799 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1801 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1802 use ">&-" since we're only 99.999% sure that this is portable,
1803 and since the MinGW bug is fixed in a different way.
1804 * lib/autotest/general.m4 (AT_INIT): Likewise.
1806 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1808 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1809 before opening config.log, to avoid hitting a bug on MinGW.
1811 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1813 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1814 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1815 This works around a MinGW bug reported by Eric Paire.
1816 Make sure that all writes to the log file append to it,
1817 rather than possibly losing data.
1818 * lib/autotest/general.m4 (AT_INIT): Likewise.
1820 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1822 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1823 description.
1825 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1827 * NEWS: Update.
1829 * configure.ac (AC_INIT): Bump to 2.59d.
1831 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1833 Version 2.59c.
1835 * Makefile.maint (news-date-check): Do not require a leading `*'
1836 before the release date in NEWS.
1838 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1839 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1841 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1842 the instantiated file do not contain the string 'datarootdir'
1843 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1844 @mandir@, replace the reference '${datarootdir}' by the value.
1845 * tests/torture.at (datarootdir workaround): New test.
1846 * NEWS: Advertise this temporary fixup.
1847 Based on a patch by Bruno Haible, reported and analyzed by
1848 Paul Eggert and Noah Misch.
1850 2006-04-12 Eric Blake <ebb9@byu.net>
1852 * tests/autotest.at (Debugging a failed test): Fix comment.
1854 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1856 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1857 all the changes since 2006-04-07.
1859 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1861 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1862 succeeded, but `ln -s file dir' failed, take care to remove the
1863 leftover target before the next test, to prevent its spurious
1864 failure; also make sure `ln file dir' works before selecting it.
1865 Thanks to Keith Marshall for pointing this out.
1866 * THANKS: Update.
1868 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1869 assignments in `at_debug_args', so that we put them correctly
1870 in the `run' script.
1871 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1872 Reported by Eric Blake.
1874 2006-04-11 Eric Blake <ebb9@byu.net>
1876 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1877 top-level tests after micro-suite has been run. Used in...
1878 (Debugging a successful test, Debugging script and environment),
1879 (Debugging a failed test): ...these new tests. The first of these
1880 is fixed by...
1881 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1882 macro, split out from...
1883 (AT_INIT): ...here, so that using -d also generates a run script.
1884 Document that -d inhibits top-level logging.
1885 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1886 inhibits top-level logging; debug scripts are created.
1888 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1889 check.
1890 * tests/autotest.at (Empty test, Empty check): New test to check it.
1892 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1893 from gcc.
1895 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1897 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1898 the files if a problem appears. Make the empty *.at files
1899 read-only, too. Proposed by Ralf Wildenhues.
1901 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1903 * config/Makefile.am: Add comment to force updated Makefile.in.
1905 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1906 space only patch to this file, this patch causes the Makefile.in
1907 files that include freeze.mk to be updated, and thus have a
1908 newer time stamp again, which in turn makes a pristine CVS
1909 checkout have correct time stamps.
1911 * Makefile.maint (cvs-sv): New macro, to be used..
1912 (config.guess-url_prefix, config.sub-url_prefix)
1913 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1914 point to CVS text checkout of Gnulib files.
1915 (copyright-check): Bump current year.
1916 (announcement): Do not hard-wire `./announce-gen'.
1917 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1918 correctly.
1919 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1920 `chmod +x'.
1921 (wget_files): Update config.guess, config.sub, texinfo.tex by
1922 `wget-update', now that their URLs work again.
1924 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1926 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1927 Problem noted by Paul D. Smith.
1929 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1931 * doc/autoconf.texi: Remove unused words from word list.
1932 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1933 .x-sc_trailing_space: New files.
1935 * doc/standards.texi: Sync from gnulib.
1937 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1938 `LIBOBJDIR' as experimental.
1940 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1941 with a target directory; it's internally implemented as `cp'
1942 anyway, but since Autoconf advertises the possibility to use
1943 a target directory when LN_S is `ln -s', we need to find out.
1944 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1945 analyzed by Keith Marshall <keith.marshall@total.com>.
1947 * THANKS: Update.
1949 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1951 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1952 confdefs.h as-is. In general, if it has backslash-newline or the
1953 like, then it doesn't work either to sort or to remove empty
1954 lines.
1956 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1958 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1960 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1962 * lib/autom4te.in (Automake-preselections): Preselect
1963 _AM_SUBST_NOTMAKE.
1965 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1967 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1968 apostrophe within a single-quoted string, as this is the usual
1969 tradition and is easier to read than '"'"'. Don't rely on the
1970 shell treating "$/" like '$/'. Use a more-consistent indenting
1971 style for the trap.
1973 2006-04-09 Eric Blake <ebb9@byu.net>
1975 * tests/autotest.at (Backquote command substitution),
1976 (Multiline backquote command substitution): Remove mistaken
1977 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1978 applied...
1979 (Parenthetical command substitution, Multiline parenthetical
1980 command substitution): here.
1982 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1984 Import macros from gnulib (often changing their name).

2000 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
2001 Gnulib section.

2012 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2013 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2014 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2015 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2016 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2017 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2018 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2019 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2020 (Coding Style). Don't mention m4_expand_once.
2021 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
2022 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
2023 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.

2031 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
2032 Catch a bug in an HP-UX C compiler.
2033 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
2034 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

2038 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
2039 New macros.
2041 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
2042 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
2044 2006-04-08 Stepan Kasal <kasal@ucw.cz>
2046 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
2047 of the warning introduced by the 2001-08-28 change.
2049 2006-04-08 Stepan Kasal <kasal@ucw.cz>,

2055 that contains braces.
2057 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2059 Revert the patch from 2006-04-01 and only improve
2060 _AS_DETECT_BETTER_SHELL:
2062 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2063 skip nonexistent directories.
2064 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2065 only shell candidates which exist.
2066 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2067 * lib/autotest/general.m4 (AT_INIT): No need to give three
2068 parameters to _AS_PATH_WALK.
2070 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2071 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2073 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2074 distinguish m4sugar macros.
2075 * tests/tools.at (autoupdating with aclocal and m4_include):
2076 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2077 test case by Noah Misch <noah@cs.caltech.edu>.
2079 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2081 Revert my change from 2006-03-17, in other words:
2082 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2083 and DUALCASE=1.
2084 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2085 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2086 it is set.
2088 2006-04-07 Eric Blake <ebb9@byu.net>
2090 * doc/autoconf.texi (Programming in M4sh): Document that
2091 AS_MKDIR_P exits the script on failure.
2092 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2094 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2096 * config/elisp-comp, config/install-sh, config/mdate-sh,
2097 config/missing, config/mkinstalldirs: Sync from Automake.
2099 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
2100 from Automake.
2102 * doc/make-stds.texi: Sync from gnulib.
2104 2006-04-06 Eric Blake <ebb9@byu.net>
2106 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2107 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2108 2006-04-01.
2110 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
2111 Eric Blake <ebb9@byu.net>,
2112 Paul Eggert <eggert@cs.ucla.edu>,
2113 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2115 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2116 whether `set' quotes correctly: redirect stderr of the tested
2117 `set', and use a subshell, for Ultrix; use `sed' instead of
2118 `grep' for zsh `set' which may write binary output; match only
2119 at the beginning of a line, to avoid false positives.
2120 In order to avoid false positives by unrelated variables with
2121 multiline content, put the dump algorithm in a subshell and
2122 unset all variables containing newlines (except some which are
2123 special to the shell). Warn about cache variables that are
2124 unset.
2126 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2128 * config/config.guess, config/config.sub, config/texinfo.tex:
2129 Sync from upstream.
2131 * tests/mktests.sh: Reword comments.
2133 * tests/mktests.sh: Only skip internal macros starting with
2134 `_AC_' or `__AC_'. Noted by Stepan Kasal.

2136 (AC_ARG_VAR): Do test this now.
2137 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
2138 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
2139 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
2140 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
2142 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
2143 shell issue with double-quoted command substitutions of native
2144 commands.
2145 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
2146 Marshall.
2148 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
2149 no file matches the glob, discard the warning, set `nullglob'.
2150 (syntax-check): Likewise.
2151 (sc_cast_of_x_alloc_return_value): Likewise.
2152 (sc_cast_of_alloca_return_value, sc_error_exit_success)

2154 (m4-check): Likewise.
2155 (sc_system_h_headers): Do not print rule on execution.
2156 (sc_tight_scope): Do not fail for non-existing `src' directory.
2157 (sc_changelog): Skip the Copyright footer.
2158 * lib/autoconf/lang.m4: Remove trailing space.
2160 * lib/autoconf/status.m4: More replacements to
2161 <tab><space> where this makes sense.
2163 2006-04-06 Stepan Kasal <kasal@ucw.cz>
2165 * tests/Makefile.am (maintainer-check-posix):
2166 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
2168 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
2169 ac_config_<foo>s again, sometimes normalized, sometimes not.
2170 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
2171 (AC_CONFIG_COMMANDS): Do not do so here.
2172 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
2173 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
2174 2005-07-25 rewrite. Noticed by Noah Misch.
2176 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
2177 _AC_PRESERVE_HELP_ORDER, ...
2178 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
2180 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
2181 inside m4_expand_once; it is redundant.
2183 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
2184 for --help from Cygnus `configure.'
2186 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
2188 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
2189 on a patch proposed by Ralf Wildenhues.
2191 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2193 * lib/autoconf/status.m4: Replace <space>''<tab> with
2194 <tab><space> where this makes sense.
2196 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
2197 Noah Misch <noah@cs.caltech.edu>
2199 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
2200 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
2201 * doc/autoconf.texi (Help Formatting): New node.
2202 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
2204 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2206 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
2207 lib/autoconf/specific.m4, lib/autoconf/status.m4,
2208 lib/autoconf/types.m4, lib/autotest/general.m4,
2209 tests/mktests.sh, tests/torture.at: White space cleanup:
2210 remove some SPACE before TAB, or add quoting ('' or @&t@).
2212 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
2214 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
2216 2006-04-05 Eric Blake <ebb9@byu.net>
2218 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
2219 empty test suite works.
2220 * tests/autotest.at (Empty test suite): Remove xfail.
2222 2006-04-05 Noah Misch <noah@cs.caltech.edu>
2224 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
2225 TAGS to ac_config_<foo>s.
2226 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
2227 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
2228 normalizing it, consistent it with previous releases.
2229 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
2231 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2233 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
2234 Use simplified args that Eric Blake originally suggested.
2236 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
2238 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
2239 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
2240 Use 'comm' rather than N instances of grep; this also fixes a bug
2241 whereby substrings were incorrectly matched, causing us to not
2242 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
2243 (exclude_list): Exclude empty macros.
2244 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
2246 Use awk rather than grep -E or egrep, to avoid
2247 portability problems with regular expressions containing newlines.
2248 (exclude_list, ac_exclude_list, au_exclude_list, ac_exclude_script):
2249 Switch from grep to awk syntax.
2250 (ac_exclude_script): Renamed from ac_exclude_egrep.

2331 initial `rm' of the candidate files...
2332 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2333 the same list in subsequent `rm' calls, and for the temporary

2335 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2336 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2337 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or

2418 switch all of them on and of when necessary. Fixes the bug when
2419 m4sugar macros (e.g., m4_define) were expanded after the first
2420 automatic update (e.g., after AC_PREREQ or AC_INIT).
2422 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

2656 (AC_FOO_IFELSE vs AC_TRY_FOO): Don't use #error; test programs

2674 HP-UX sed is 99 commands, not 100.
2675 (_AC_OUTPUT_FILES_PREPARE): Do not count the `}' of an
2676 _AC_SUBST_FILES fragment. Separate `{' and `r' commands by
2677 newline for portability.
2678 * tests/torture.at (Torturing config.status): Also test 100

3175 calls, so that the final expansion of this macro is shorter.
3176 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3177 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3178 the cleanup there. Use AS_VAR_* macros, to be more general.
3179 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3181 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3183 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
3185 2005-09-01 Stepan Kasal <kasal@ucw.cz>
3187 * doc/autoconf.texi (Configuration Headers): Add an index entry
3188 for AH_HEADER.
3190 2005-08-26 Pavel Roskin <proski@gnu.org>
3192 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
3193 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
3194 running xmkmf.
3196 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
3198 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3199 The previous patch didn't work, so try a better one.
3201 2005-08-26 Stepan Kasal <kasal@ucw.cz>
3203 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3204 in the example. Reported by Bruno Haible.
3205 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3206 "if $undefined_var;" succeeds with my shell.
3208 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
3209 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
3210 but change the m4_divert_text to m4_divert_once.
3212 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
3214 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3215 Work around bug in Solaris /usr/xpg4/bin/awk.
3216 The bug is present in at least Solaris 8 through 10.
3218 2005-08-24 Stepan Kasal <kasal@ucw.cz>
3220 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
3221 some evil values and relying on the fact that $* concatenates the
3222 parameters by the first character from IFS.
3224 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3225 Stepan Kasal <kasal@ucw.cz>
3227 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
3228 first header appears, define AH_HEADER.
3229 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
3230 Update limitations about when to call AC_CONFIG_HEADERS.
3231 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3232 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3233 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3234 ``Configuration Actions''; fix their index entries.
3236 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3237 options correctly. Process N-M as M-N if M is smaller than N.
3238 Process ranges correctly so that N-N will run only N.
3239 Sort and uniquify the tests that will be run. If there is more
3240 than one test, reinsert the banners for the tests.
3241 * tests/autotest.at (Keywords): Unmark XFAIL.
3243 2005-08-23 Stepan Kasal <kasal@ucw.cz>
3245 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
3246 before passing the macro name to AH_TEMPLATE.
3248 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3249 now opens log after option processing; in particular, --version
3250 and --help do not touch config.log.
3252 * Makefile.maint: Revert the change from 2005-08-12.
3254 2005-08-22 Stepan Kasal <kasal@ucw.cz>
3256 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
3257 common code to...
3258 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
3260 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3262 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
3263 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
3264 Language cleanup.
3266 * doc/autoconf.texi (Defining Symbols, Changed Results):
3267 Prepend to LIBS, not append, in examples.
3269 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3271 When building in place, set srcdir="."; suggested by Tim Van Holder.
3273 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3274 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3275 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3276 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
3277 does not mean "no --srcdir option".
3279 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3281 * tests/autoscan.at (autoscan): New file.
3282 * tests/suite.at: Use it.

3288 2005-08-12 Stepan Kasal <kasal@ucw.cz>
3290 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
3291 add "2>&1"; gzip 1.2.4 prints help on stderr.
3293 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3295 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
3296 was pushdef'ed twice while popped only once. Push it only once.
3297 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
3299 2005-07-26 Stepan Kasal <kasal@ucw.cz>
3301 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

3306 * Makefile.maint: Update from Bison.
3308 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3309 "<tab>" in comment, so that the point is understandable.
3311 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3313 Rewrite substantial part of lib/autoconf/status.m4.
3314 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3315 and CONFIG_COMMANDS are not processed in four separate loops.
3316 Instead, there is one main loop. This alows that the common code
3317 is expanded only once, thus config.status (and configure) is smaller.
3319 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3320 the AC_LIST_FILES and cousins macros are no longer used.
3322 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3323 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3324 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3325 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3326 contain the initialization, nor the for loop, nor the associated
3327 commands; all these go to ...
3328 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3329 _AC_OUTPUT_CONFIG_STATUS.
3330 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3331 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3332 (_AC_OUTPUT_FILE): The creation of the sed script ...
3333 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3334 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3335 _AC_OUTPUT_MAIN_LOOP.
3336 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3337 _AC_CONFIG_COMMANDS): Use ...
3338 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3339 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3340 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3341 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3342 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3343 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3344 ... new macros.
3345 (_AC_CONFIG_UNIQUE): Update.
3346 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3347 Replaced by this ...
3348 (_AC_LIST_TAGS): ... new common macro.
3349 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3350 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3351 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3352 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3353 this didn't belong to the `config commands' section.
3354 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3355 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3356 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3357 to the `config commands' section either.
3358 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3359 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3361 ... and many changes to the comments nearby.
3363 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3364 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3365 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3366 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
3367 (#define header templates): The comment at the top of the generated
3368 header now includes the name(s) of the source file(s).
3370 Several unrelated small changes:
3372 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
3373 parameter to AC_DIAGNOSE.
3374 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
3375 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
3376 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
3377 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
3378 with AU::AC_OUTPUT.
3379 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
3380 in AC_OUTPUT doesn't double-quote it either.
3381 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
3382 parameters.
3384 2005-07-10 Stepan Kasal <kasal@ucw.cz>
3386 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
3387 versions of Portland Group compiler produce single- and double-quoted
3388 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
3389 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3391 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3393 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3394 This is a corrected version of yesterday's patch.
3396 2005-07-07 Stepan Kasal <kasal@ucw.cz>
3398 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
3399 path, too; insert a "===" to emphasize the line.
3401 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
3402 ac_cv_build_alias to ac_build_alias.
3403 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3405 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3406 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3407 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3408 (AC_ARG_VAR): ... here.
3409 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3410 target_alias.
3412 Keep a list of all precious variables and process them with one simple
3413 for loop, instead of expanding all commands, or, OTOH, complicated
3414 processing of output of "set".
3415 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3416 variable names in new macro...
3417 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
3418 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
3419 a loop to assign all ac_env_* and ac_cv_env_* variables.
3420 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3421 to INIT_PREPARE.
3422 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3423 its value to shell variable ac_precious_vars and call
3424 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
3425 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
3426 _AC_ARG_VAR_VALIDATE.
3428 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
3429 and the AC_SUBSTs ...
3430 (AC_INIT): ... here.
3432 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
3433 the ac_subst_files section in config.log.
3435 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
3437 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

3442 * tests/c.at (C keywords): Test AC_C_TYPEOF.
3444 Fix problems reported by Nicolas Joly.
3445 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
3446 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3447 They are generated by the Tru64 v5.1B shell.
3449 2005-07-05 Stepan Kasal <kasal@ucw.cz>
3451 Fix my changes from 2005-07-01; reported by Noah Misch.
3452 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
3453 description, the macro now accepts only a single tag.
3454 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
3456 Fix cases when the varsions of Autoconf and Autotest don't match.
3457 Reported by Noah Misch.
3458 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
3459 at_top_builddir, for compatibility with older autotest.
3460 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
3461 is not set, use at_top_builddir, for compatibility with older
3462 versions of autoconf.
3464 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
3466 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
3467 Problem reported by Patrick Welche.
3469 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
3471 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
3472 sed substitution command, so that we allow | in program prefixes
3473 and program suffixes. (& is a problem anyway; we're not fixing
3474 that here.)
3475 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
3476 configure_input, top_builddir, srcdir, etc.
3477 * lib/autotest/general.m4 (AT_INIT): Likewise, for
3478 PATH_SEPARATOR in AUTOTEST_PATH.
3480 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

3483 for loop over config.site files using `set', to allow
3484 directory names containing IFS characters.
3486 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
3488 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
3489 directories with weird names. Apparently some people like living
3490 on the edge. However, improve the test that "pwd" actually does
3491 report a name for the working directory.
3492 * NEWS: Remove the claim that we test for funny chars in dir names.
3494 2005-07-01 Stepan Kasal <kasal@ucw.cz>

3507 (Generic Functions): Mention the Gnulib project.
3508 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
3510 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
3511 document to output the default config_* lists to config.status.
3512 Don't recognize option --file, if the functionality is not there.
3513 Likewise for --header; moreover, recognize --he and --h as shortcuts
3514 for --help in that case.
3516 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
3517 matches the order of execution. No code changed.
3519 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3521 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for

3538 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
3539 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
3540 (AC_SUBST): Call it.
3541 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
3542 the directory specific variables; but don't call it for configure_input.
3544 2005-06-28 Derek Price <derek@ximbiot.com>
3546 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
3547 addition.
3549 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
3551 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
3552 directory have inherent problems with special characters like spaces,
3553 due to limitations in Make syntax. Problem reported by Alexandre
3554 Duret-Lutz.
3555 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

3567 Fix some more shell quoting problems. Prompted by a bug report
3568 from Justace Clutter.
3569 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
3570 variable into diagnostic. Make the diagnostic an error, not a warning,
3571 because we really don't support spaces and suchlike in dir names.
3572 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3573 Don't worry about backslashes in srcdir; it can't happen now.
3574 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
3575 Simplify ac_optarg handling.
3576 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

3584 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
3586 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
3587 that '\|' is not allowed in BREs; recommend using newline separated
3588 list of patterns instead of multiple -e options.
3590 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
3592 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

3598 2005-06-21 Stepan Kasal <kasal@ucw.cz>
3600 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
3601 b, t, r, w commands require single space, while : cannot have any.
3602 (Special Shell Variables): Fix sed code this in the example.
3603 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
3604 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
3606 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
3607 expand to the empty list. Don't use two pairs of m4_changequote,
3608 it's not necessary.
3610 2005-06-20 Derek Price <derek@ximbiot.com>
3612 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
3614 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
3616 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
3617 * doc/autoconf.texi:
3618 Don't mention Solaris versions so much, if a
3619 problem is common to all extant versions of Solaris. Say "SunOS
3620 4" instead of "SunOS" for SunOS 4.
3621 (awk): Mention more of the limitations of traditional Awk.

3626 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
3627 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
3628 but the implementation is entirely different and is designed
3629 to be compatible with glibc strverscmp.
3630 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
3632 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
3633 on Mac OS X 10.4 reported by Peter O'Gorman in:
3634 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
3635 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
3636 Use shell builtins rather than 'expr', to work around expr bug.
3638 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
3640 * doc/autoconf.texi: "filesystem" -> "file system".
3641 "behaviour" -> "behavior".

3644 as per POSIX.
3645 * lib/m4sugar/m4sh.m4: Likewise.
3646 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
3647 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
3649 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
3650 (.x.1): Ignore the time stamp in the .TH line when deciding whether
3651 to update the man page. That way, we don't have to check in new
3652 man pages every month.
3654 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
3655 quotes and backslashes. Patch from Derek Price.

3660 AS_TR_SH.
3662 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
3664 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3665 -u, since it outputs chatter if the input files are the same.
3666 Problem reported by Ralf Menzel.
3668 2005-06-08 Derek Price <derek@ximbiot.com>
3670 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3671 renaming them since they are about to be redefined anyhow.
3673 2005-06-08 Derek Price <derek@ximbiot.com>
3675 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3676 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3677 Move m4_undefine to alphabetical order.
3679 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
3681 * README: Recommend GNU M4 1.4.3 or later.
3682 * doc/autoconf.texi (Introduction): Likewise.
3683 Reword to avoid some formatting glitches.
3684 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
3685 Clarify explanation of HP compiler bug.
3686 Redo example output tp match current CVS snapshot.
3687 Use @example.org in email addresses when the examples
3688 might get inadvertently cut-and-pasted into user code.
3689 Remove example of autom4te usage that doesn't seem to work now.
3690 Use modern AC_INIT (except when the example is meant to be
3691 shown with Autoconf 2.13).
3692 Update ksh info for Solaris 9 and later.
3693 KB -> kB.
3694 Modernize description of Automake versions a bit.
3695 Don't claim a future version of Autoconf is near.

3698 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3700 * doc/autoconf.texi: Add [] to examples, so that the manual
3701 follows its own advice about quoting better.
3702 Reword to avoid some formatting glitches.
3703 * doc/installt.exi: Reword to avoid some formatting glitches.
3705 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3706 Tru64 ksh pattern matching bug. Reported against Libtool by
3707 Albert Chin <libtool@mlists.thewrittenword.com> and
3708 Nicolas Joly <njoly@pasteur.fr>.
3710 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3712 m4_cdr of one-member list was [[]] (one-member list containing an
3713 empty string) instead of [] (an empty list. Callers were skewed to
3714 match this misbehaviour. As a consequence of this:
3715 - m4_foreach([x], [], [foo]) expanded to `foo', while
3716 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3717 This bug has been fixed:
3719 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3720 expand to an empty string; print error msg if called without
3721 an argument list.
3722 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3723 misbehaviour; handle [] and [[]] correctly.
3725 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3727 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
3728 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
3729 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
3731 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3733 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3734 swallow records with more than 99 fields.
3735 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3736 parse the long line.
3738 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3740 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3741 swallow literals longer than 399. Reported by Ralf Wildenhues.
3742 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
3743 to workaround this limitation.
3745 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
3747 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
3748 to gfortran, and make these the first two compiler names
3749 checked (following the general autoconf preference for gcc).
3751 2005-06-03 Stepan Kasal <kasal@ucw.cz>
3753 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3754 (DISTCLEANFILES): Remove $(check_SCRIPTS).
3755 (testsuite): Make sure autotest.m4f is up-to-date before using it.
3757 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
3759 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3760 expression of unbounded size when processing the --list
3761 option. This runs afoul of a limit of 399 bytes per regular
3762 expression on AIX. Problem reported by Ralf Wildenhues.
3764 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
3766 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
3767 * doc/autoconf.texi (Particular Headers): Reword example
3768 for multiline stdbool replacement.
3769 (Setting Output Variables): Reword text a bit. Don't
3770 give all the details about |#_!!_#|.
3771 Reword description of line replacement.
3773 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3775 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3776 now contain newlines, and substituted files must be referenced on
3777 a line alone; the sed scripts to substitute them are now very
3778 different.
3779 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3780 commands can be put in a sed script portably.
3781 * doc/autoconf.texi (Setting Output Variables): Document above
3782 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
3783 use of multiline substitution.

3793 * tests/local.at: Don't attempt to check for negated character
3794 classes in shell scripts. The test was too brittle.
3796 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3798 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3799 * doc/autoconf.texi (Limitations of Builtins): Document this
3800 limitation.
3802 2005-05-24 Stepan Kasal <kasal@ucw.cz>
3804 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
3805 common code; used in many places in the tree.
3806 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
3807 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
3809 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
3811 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
3812 messages when ac_unique_file is not found.
3813 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3814 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
3815 commands, for consistency with AC_MSG_ERROR and such.
3817 * bin/autoconf.as: Make more use of "shift 2" in option processing.
3819 * bin/Makefile.am: Merge the two rules for creating scripts.

3827 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3829 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
3830 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3831 (ac_top_builddir): ... this ...
3832 (ac_top_build_prefix): ... to this; the old name is also kept, for
3833 backward compatibility.
3834 (ac_top_builddir_sub): New variable, without the trailing slash,
3835 always nonempty.
3836 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
3837 * doc/autoconf.texi (Configuration Actions): Rename
3838 ac_top_builddir to ac_top_build_prefix.
3839 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
3840 at_top_builddir to at_top_build_prefix.

3845 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
3846 of confdefs.h .
3848 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3850 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3851 argument to m4_foreach. I guess it was necessary in the past,
3852 but I think it's a no-op now.
3854 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3856 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3857 ``cat <<_ACEOF'' commands to one.
3858 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3859 * lib/autoconf/status.m4: On various places, use expr instead of
3860 ``echo|sed.''
3861 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3862 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3863 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3864 a range.
3865 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
3866 the wrong patterns between ``case'' and ``esac.'' The previous
3867 code had false positives.

3871 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3872 as on 2005-05-02.
3873 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
3874 Mention LIBOBJDIR.

3936 quoting rules. Problems noted by Stepan Kasal.
3937 Also, throughout this document, be more careful about white space.
3938 "blank", "white space", and "space" all have different meanings
3939 and we should be careful to say what we mean.
3941 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>

4000 * lib/autoconf/functions.m4
4001 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

4071 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4072 (AC_INIT): Use it.
4073 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4074 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4075 ac_pwd, and quote srcdir.
4076 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4078 * doc/autoconf.texi: Fix some systematic formatting problems.
4079 ".)" needs a following @: if not at the end of a sentence, and
4080 similarly for "!)". "etc." should be preceded by a comma.
4081 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4083 2005-03-22 Bruno Haible <bruno@clisp.org>
4085 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4086 argument is often called 'build-aux'.
4088 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4090 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4091 macro AC_TRY_LINK is obsolete.
4092 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4093 `AC_CONFIG_FILES'.
4095 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4097 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4098 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4099 from a Common Lisp's `cl'.
4100 (AC_PROG_CXX): Behave according to the documentation: don't
4101 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4102 make the variable CCC precious; use `cl.exe', not `cl'.
4104 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4105 Alexandre Duret-Lutz <adl@gnu.org>
4107 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4108 /dev/null, as "configure" shouldn't read stdin, and this insulates
4109 us from problems (e.g., when testing for "cl"). Also, do this
4110 redirection before invoking "hostname" or "uname", and keep the
4111 original input stream available via...
4112 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4113 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4114 bother with "</dev/null" since it's now done at the top of
4115 'configure'.
4116 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4117 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4118 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

4123 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4125 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4126 newline if neither \c nor -n work, as that would output two
4127 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4129 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4131 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4132 This causes that any required macros inside will get before the if.
4133 * doc/autoconf.texi (autom4te.cache): A typo.
4135 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4137 Undo previous change, except keep the change to
4138 lib/autoconf/programs.m4 that replaced grep with shell
4139 pattern-matching. This is because net-snmp configure reads stdin.
4140 Reported by Noah Misch.
4142 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4144 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4145 from /dev/null, as "configure" shouldn't read stdin, and this
4146 insulates us from problems (e.g., when testing for "cl").
4147 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4148 before invoking "hostname" or "uname".
4149 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4150 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4151 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4152 "</dev/null" since it's now done at the top of 'configure'.
4153 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4154 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4155 Also, replace grep with shell pattern-matching, to save a process.
4157 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4159 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4160 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4161 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4162 compiler.
4164 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4166 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4167 grep -q isn't portable. Improve grep -s explanation.
4168 Problem reported by Dan Manthey.
4170 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4172 * doc/autoconf.texi (Special Shell Variables): Clarify
4173 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4175 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4177 * doc/autoconf.texi: Use @acronym for DJGPP.
4178 Fix some @code's that should have been @env's, and vice versa.
4179 Sort environment variable names.
4180 Mention that shells no longer inherit IFS.
4181 Don't recommend PATH_SEPARATOR=';' so strongly.
4182 Mention that $RANDOM might expand to the empty string.
4183 "symlink" and "soft link" -> "symbolic link".
4184 Improve mktemp description (reported by Bruno Haible).
4186 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
4188 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
4189 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
4190 Likewise.
4191 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
4192 Likewise.
4194 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
4196 * NEWS: Mention AT_COPYRIGHT.
4198 * tests/local.at (AT_CMP): Use diff directly on input files rather
4199 than copying them.
4201 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
4202 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
4204 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4205 and Paul Eggert <eggert@cs.ucla.edu>
4207 * tests/autotest.at (Empty test suite): New test.

4212 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4214 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
4215 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
4216 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
4217 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
4218 (Standard regular expressions): New test.
4219 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
4220 excess test name quoting.
4221 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
4222 CPPFLAGS to `configure' instead of setting it in `configure'.
4224 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
4225 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
4226 on some platforms.
4228 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
4229 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

4232 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

4236 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
4237 * tests/c.at (Extensions): Do not exit early.

4257 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
4259 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
4260 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4262 Try not to generated lines of unlimited length, as POSIX places a
4263 2047-byte limit on line length of portable text files.
4264 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
4265 Use newline as a separator, not space.
4266 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
4267 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
4268 space.
4270 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4272 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
4273 as_func_*. Add test to check whether positional parameters
4274 are restored after function return.
4276 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
4278 * doc/autoconf.texi (Special Shell Variables): Mention _,
4279 BIN_SH, DUALCASE. Say that variables other than "status" are safe
4280 if they contain a lower-case letter. The DUALCASE problem was
4281 reported by Ralf Wildenhues.
4283 * bin/autoconf.as: Don't exit with status 0 after write failure
4284 with --help or --version.
4285 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

4291 Unicos 9 sed limitations.
4292 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

4294 Fortran 95 (newer Crays).
4296 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
4298 * man/Makefile.am (.x.1): Go back to the simple solution, but take
4299 care to echo the commands, so the user knows what's going on.
4300 Modified from a suggestion by Stepan Kasal.
4302 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

4310 Based on a proposed patch by Ralf Wildenhues.
4312 * man/Makefile.am (.x.1): Make sure the required generated files
4313 are up to date. Problem and original solution proposed by Stepan Kasal.
4314 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
4315 implicit-man-prerequisites): New rules, used by the above.

4321 2005-01-29 Stepan Kasal <kasal@ucw.cz>
4323 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4324 Update the long comment explaining it.
4326 m4_require no longer writes an ``is required by'' line to the
4327 execution stack. It contains only one bit of non-redundant
4328 information: that the macro was required, not called. And even
4329 this bit is useless in most situations: have you ever met a macro
4330 which both calls and requires the same macro?
4332 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4333 (_m4_defun_pro_outer): ... only via this macro, for the outermost
4334 macro.
4335 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
4336 (m4_expansion_stack_pop): Remove the misplaced comment.
4337 (m4_require): Don't put the ``is required by'' line to the
4338 execution stack; slightly improve the out-of-a-defun error message.
4339 (_m4_divert_grow): New macro, counter for the temporary diversions.
4340 (_m4_require_call): Use it.
4341 * tests/m4sugar.at (m4_require): Expect output without the
4342 ``is required by'' messages.
4344 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4346 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4347 rather than x for expr.
4349 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
4350 this is safe.
4351 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
4352 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

4361 * doc/make-stds.texi, doc/standards.texi: Update from masters.
4362 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
4363 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
4364 from masters, so that FileUtils.pm's update_file provide --force
4365 support.
4366 * bin/autoheader.in: Pass $force to update_file so that
4367 config.h.in is always recreated when --force.
4369 2005-01-24 Stepan Kasal <kasal@ucw.cz>
4371 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
4373 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
4375 * doc/autoconf.texi (Limitations of Builtins): Clarify that
4376 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
4378 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
4380 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
4381 Warn about newline stripping in `` and $(). Update Solaris
4382 version to 9.
4383 (Limitations of Builtins): Use expr "X...", not expr "x...", as
4384 X insulates us from future changes to Posix.
4385 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
4386 stripping.
4388 2005-01-19 Stepan Kasal <kasal@ucw.cz>
4390 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
4391 you cannot use AC_DEFINE to define macros containing `[' or `]'.
4393 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
4395 * doc/autoconf.texi (Limitations of Usual Tools): Document bug

4406 ulongval to be static, to avoid unwanted GCC warning. Problem
4407 reported by Michael Jennings via Daniel Reed; see
4408 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
4410 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
4412 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

4417 new variables.
4419 2005-01-04 Noah Misch <noah@cs.caltech.edu>
4421 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
4422 not seem to work, assume it does set $(MAKE).
4423 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
4425 2005-01-03 Stepan Kasal <kasal@ucw.cz>
4427 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

4433 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
4434 (_m4_divert_n_stack): New macro; the expansion is
4435 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
4436 otherwise.
4437 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
4438 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
4439 stored in _m4_divert_diversion or _m4_divert_dump.
4440 (m4_divert_pop): When the parameter is given, compare the symbolic
4441 name with the last diversion pushed on the stack. Previously, the
4442 current diversion was compared with the numeric value of the
4443 diversion given as the parameter.
4444 (m4_require): If the macro hasn't been expanded yet, call ...
4445 (_m4_require_call): this new macro.
4447 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4478 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
4479 signals that the package uses Automake; a `Makefile.am' is typical but
4480 not essential. Reported by Magnus Therning.
4481 * tests/torture.at (autoreconf.): New banner.
4482 (autoreconf and non-AC configure): Rename to `Non-Autoconf
4483 AC_CONFIG_SUBDIRS'.

4752 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use

4871 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns

4974 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4975 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4976 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4977 * lib/autom4te.in (Automake-preselections): Preselect
4978 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4980 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4982 * lib/autom4te.in (Automake-preselections): Preselect
4983 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4984 trace them.
4986 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4988 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4989 Tru64.
4990 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4991 Document problem with "`""`" in pdksh POSIX mode.
4993 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4995 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4996 with pdksh, too. Problem reported by Patrick Welche via
4997 Gary V. Vaughan.
4998 * doc/autoconf.texi (Shellology): Note that set -o posix is
4999 useful for pkdsh, too.
5001 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5003 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5004 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5005 Don't fail if ENV or BASH_ENV is readonly.
5006 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5007 etc. are read only. Problem reported by Ludovic Courtes.
5009 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5011 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5012 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5013 (trivial change)
5015 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5017 * doc/autoconf.texi (File System Conventions): Warn about
5018 names like "aux". Problem reported by Eric Blake.
5020 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5021 by zero instead of array size, so that we can use any arithmetic
5022 constant expression (instead of requiring an integer constant
5023 expression). This allows us to test expressions like DBL_MAX <
5024 LDBL_MAX, which didn't conform to the C standard using the old
5025 method.
5026 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5027 now that we can do floating-point tests at compile time.
5029 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5031 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5032 and LDBL_EPSILON, as the resulting expression isn't an
5033 integer constant expression and violates the C standard.
5034 Problem reported by Nelson H. F. Beebe. Also, check
5035 for "L" suffix, and check that long double doesn't have
5036 worse range or precision than double, that mixed-mode
5037 arithmetic doesn't generate a diagnostic, that double
5038 constants fit in long double.
5040 2004-06-03 Kevin Ryde <user42@zip.com.au>
5042 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5043 malloc(0) and realloc(NULL,size).
5045 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5046 Bob Proulx.
5048 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5050 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5051 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5052 by Jim Meyering.
5054 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5056 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5057 can be rewritten using if-then-else. Suggested by Bruno Haible.
5059 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5061 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5062 Problem reported by Stepan Kasal.
5064 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5066 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5067 change). Patch reported by Ralf Wildenhues in
5068 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5070 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5071 function F exists if the compiler and linker let you compile an
5072 expression like (F != 0). Recent versions of GCC optimize away
5073 the reference to F in that case, since every function address must
5074 be nonzero, so the link succeeds even if F does not exist.
5075 Problem reported by Manu in
5076 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5078 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5079 "Unix". Many uses changed.
5080 (Limitations of Builtins): Explain better why the ! command isn't
5081 portable.
5083 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5085 * lib/autom4te.in (Automake-preselections): Preselect
5086 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5088 2004-05-19 Kevin Ryde <user42@zip.com.au>
5090 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5091 referencing AC_FUNC_STRERROR_R.
5093 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5094 note pessimistic assumption when cross compiling.
5096 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5098 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5099 (until 2004) invoked subcommands with sh -e, contra POSIX.
5100 Reported by Kevin Ryde.
5102 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5104 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5105 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5106 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5107 `test -f " /usr/bin/grep"', which _always_ failed.
5108 (AC_PROG_SED): Ditto bogus PATH fix.
5109 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5110 requires that grep correctly supports _multiple_ `-e' options, rather
5111 than stating only that grep should accept `-e'.
5113 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5115 Port to C99, which requires that 'exit' be declared.
5117 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5118 to ensure that stdlib.h is included.
5119 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5120 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5121 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5122 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5123 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5124 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5125 when using 'exit' in a test; C99 requires that 'exit' be declared.
5127 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5129 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5130 now prefers 'grep' implementations that accept -e.
5131 (Limitations of Usual Tools): Describe problems of traditional
5132 egrep and fgrep with long input lines, and of traditional grep
5133 with -e.
5134 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5135 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5136 All callers changed. Append /usr/xpg4/bin to the PATH, for
5137 Solaris.
5138 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5139 the user with complaints about multiple -e options.
5140 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5141 Define it with AC_PROG_GREP.
5142 * configure.ac (AC_PROG_GREP): Add.
5143 * lib/freeze.mk (GREP): New macro.
5145 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5147 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5148 a possible candidate only after all others fail, rather than
5149 consulting it first. This improves backward compatibility by
5150 better reflecting the way shell selection occurred in previous
5151 versions of Autoconf, and should help to avoid triggering latent
5152 problems in other packages, such as the one in Automake where zsh
5153 is not handled robustly:
5154 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5155 Although it is not Autoconf's responsibility to work around
5156 problems in Automake, it nevertheless makes sense to avoid
5157 introducing unnecessary incompatibilites.
5159 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5160 Gary V. Vaughan <gary@gnu.org>
5162 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5163 how deeply nested we are when a suitable tool is found, set the
5164 ac_path_TOOL_found flag.
5165 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5166 nested we are in this macro. Break out of all 3 nested loops if
5167 ac_path_TOOL_found is set.
5169 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5171 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5172 of the _AS_PATH_WALK loop too if GNU flavor is found.
5174 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5176 * doc/autoconf.texi (Limitations of Make): Update documentation
5177 for `$<'. New entry `Long lines', based on a report from Simon
5178 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5179 paragraph about DJGPP, based on a mail from Richard Dawe.
5181 2004-04-20 Paul Eggert <eggert@twinsun.com>
5183 * tests/c.at (C keywords): Don't assume that GCC supports
5184 "restrict" and "inline", as sufficiently-old GCC versions do not
5185 (also, GCC configured to be in pedantic C89 mode does not).
5186 Problem reported by Sumit Pandya in:
5187 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5189 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5190 consider -g to work if it generates warnings when plain compiles
5191 don't. Problem reported by Braden McDaniel in:
5192 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5194 * doc/autoconf.texi (Slashes): New section, to document a problem
5195 reported by Jim Meyering in:
5196 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5198 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5199 linker output files before linking, to work around IRIX 6 linker bug.
5200 Problem reported by Rainer Orth in:
5201 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5203 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5205 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5206 best tool so far counter rely on the tool path variable name to
5207 avoid checks for one tool being affected by the results of running
5208 the length check on a previous tool.
5210 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5211 match expression argument, as different greps have different
5212 regular expression flavours.
5213 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5214 literals.
5215 (AC_PROG_EGREP): Pass 'EGREP$'.
5216 (AC_PROG_GREP): Pass 'GREP$'.
5218 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
5220 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
5221 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
5223 2004-03-29 Paul Eggert <eggert@twinsun.com>
5225 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
5226 Types, Specific Compiler Characteristics, System Services,
5227 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5228 etc. consistently instead of 'long', 'short', 'unsigned' etc.
5229 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
5230 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
5231 Likewise.
5232 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
5233 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
5234 AC_TYPE_OFF_T): Likewise.
5235 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
5236 Likewise.
5238 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
5239 pacify libtool 1.5.2. Fix quoting problems in sed command.
5241 2004-03-28 Paul Eggert <eggert@twinsun.com>
5243 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
5244 now defines HAVE_DECL_TZNAME if it is declared, when
5245 HAVE_STRUCT_TM_TM_ZONE is not defined.
5246 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5247 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
5248 for HAVE_TZNAME.
5250 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
5252 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
5253 superfluous backslashing of quotes (") in sed expressions;
5254 thanks to Paul Eggert.
5256 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
5258 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
5259 Fortran compiler is ifort, also added pghpf; thanks to Nelson
5260 H. F. Beebe for the bug report.
5262 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
5264 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
5265 quoted -cmdline argument in Portland Group compiler (bug
5266 reported by Jeffrey J. Barteet).
5268 2004-03-25 Kevin Ryde <user42@zip.com.au>
5270 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
5271 (Run Time): ... here, where it's now mentioned.
5273 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
5275 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
5276 inherits from language Autoconf-without-aclocal-m4.
5277 (Customizing autom4te): Adjust example; the cache must now be
5278 disabled for language Autoconf-without-aclocal-m4.
5280 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
5281 Nathanael Nerode <neroden@twcny.rr.com>

5291 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
5292 AC_CHECK_TOOLS.
5293 (Specifying Names): Document the reason for these future
5294 behavioral changes.
5295 * tests/mktests.sh: Do not generate tests for the
5296 new macros.
5297 * NEWS: Document these changes.
5299 * doc/autoconf.texi: Avoid macros with unbraced arguments,
5300 they make TeX hang up.
5302 2004-03-15 Paul Eggert <eggert@bogus.example.com>
5304 * NEWS: New macro AC_CHECK_ALIGNOF.
5305 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5306 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
5307 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
5308 vowel.
5309 (AC_CHECK_ALIGNOF): New macro.
5310 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
5311 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
5312 those for sizeof.
5314 2004-03-03 Paul Eggert <eggert@twinsun.com>
5316 * bin/Makefile.am (edit): Don't use $< in a context where
5317 POSIX doesn't require support for it. Use $@.in instead.
5318 Problem reported by Anthony N. Frasso in
5319 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
5320 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
5322 2004-02-23 Gary V. Vaughan <gary@gnu.org>
5324 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
5325 from the next generation of Libtool.
5326 * lib/autom4te.in (Autoreconf-preselections): Ditto.
5328 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>

5343 one per related section. Add $(srcdir)/wrapper.in.
5345 2004-02-09 Paul Eggert <eggert@twinsun.com>
5347 * doc/autoconf.texi (Setting Output Variables): Emphasize that
5348 AC_SUBST provides no portable way to escape literal newlines.
5350 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5351 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5352 Darwin uses -lcrt2.o and there's little point to cataloging all
5353 the system variants. Partial fix reported by Andreas Waechter in:
5354 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
5355 for bug reported by Nelson H. F. Beebe in:

5367 * bin/autoupdate.in: Define __file__ so that warnings
5368 refer to the correct file.
5369 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
5370 the behavior of the third argument.
5371 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
5372 correctly the behavior of the third argument. Document
5373 what the three macros that AU_DEFUN defines do. Fix
5374 warning message when the third argument includes $0
5375 (reported by Alexandre Duret-Lutz).
5377 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5378 Eric Sunshine <sunshine@sunshineco.com>
5379 Paul Eggert <eggert@twinsun.com>
5381 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
5382 (AS_INIT): Output shell initialization there. Removed optional
5383 parameter. Expand _AS_SHELL_FN_SPY.
5384 (AS_INIT_WITH_SHELL_FN): Removed.
5385 (_AS_SHELL_FN_SPY): New macro.
5386 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
5387 macros.
5388 (AS_SHELL_SANITIZE): Remove loop to find better shell
5389 and documentation for the parameter.
5390 (_AS_DETECT_BETTER_SHELL): Move it here.
5391 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
5392 (_AS_RUN): Move it here, support testing with eval.
5393 (AS_REQUIRE_SHELL_FN): Require shell functions when
5394 it is used.
5395 (_AS_LINENO_WORKS): Put around braces, we do not
5396 trigger the bash bug anymore.
5397 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
5398 use AS_INIT_WITH_SHELL_FN.
5399 * bin/autoconf.in, tests/wrapper.in: Regenerated.
5401 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5403 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
5404 * doc/autoconf.texi: Don't say that the third parameter
5405 is broken.
5406 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
5407 (AU_DEFUN): Honor the third parameter, create autoupdate
5408 macros with AU_DEFINE.

5418 * lib/autoconf/status.m4: Remove FIXME.

5423 of autoupdate.

5429 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

5431 the 2003-05-22 change, which removed the older years from the list.
5432 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
5434 2004-01-27 Gary V. Vaughan <gary@gnu.org>

5439 possible.
5440 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
5441 AC_PROG_GREP.
5442 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
5443 egrep and fgrep respectively if $GREP -E/-F don't work.
5444 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
5445 _AC_PROG_GREP, and AC_PROG_SED.
5446 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
5447 longest input length accepted by a command.
5448 (AC_PROG_SED): Use it.
5449 * doc/autoconf.texi (Particular Programs): Document the changes.
5450 * NEWS: Updated.
5452 2004-01-27 Paul Eggert <eggert@twinsun.com>

5456 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
5457 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
5459 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
5460 bin/autoconf.in, config/Makefile.in, config/config.guess,
5461 config/config.sub, config/install-sh, config/mdate-sh,

5476 2004-01-26 Paul Eggert <eggert@twinsun.com>
5478 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
5479 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
5480 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
5481 not <inttypes.h>. Problem reported by Tim Mooney in
5482 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
5483 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
5484 Likewise.
5486 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
5487 otherwise "make check" fails because it forbids cmp (I guess
5488 because cmp treats files as binary on DOS-like systems).
5490 * tests/mktests.sh: Update copyright date to 2004, since some tests
5491 have changed in 2004.
5493 2004-01-23 Gary V. Vaughan <gary@gnu.org>

5496 non-truncating sed or gsed program in PATH.
5497 * tests/acprograms.at: Add it.

5499 * NEWS: Updated.
5501 2004-01-15 Paul Eggert <eggert@twinsun.com>
5503 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
5504 -std1 disables some useful extensions on Tru64. Problem reported
5505 by N. Lichtmaier in
5506 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
5508 2004-01-14 Paul Eggert <eggert@twinsun.com>
5510 * doc/autoconf.texi (Programming in M4sh): Document that
5511 AS_MKDIR_P succeeds if the destination is a symbolic link
5512 to an existing directory.
5513 (Limitations of Usual Tools): Note that mkdir -p might not
5514 succeed on symlinks to directories.
5516 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
5518 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
5519 * bin/autoheader.in: Grammar fix in message.
5520 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
5521 Test for dir before calling mkdir -p. (trivial changes)
5523 2004-01-13 Eric Blake <ebb9@byu.net>
5525 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
5526 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
5528 2004-01-10 Jim Meyering <jim@meyering.net>
5530 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
5532 2004-01-09 Paul Eggert <eggert@twinsun.com>
5534 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
5535 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
5536 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
5537 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
5538 AC_COMPILE_IFELSE, since we now assume our caller invokes
5539 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
5540 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
5541 of AC_RUN_IFELSE; this avoids the warning mentioned above.
5542 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
5544 2004-01-07 Paul Eggert <eggert@twinsun.com>
5546 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
5547 `"'...'"`, as it's confusing (and I suspect it may not work on
5548 some platforms). The code was incorrect anyway, as it assumed
5549 that \$ evaluated to itself in that context. Reported by
5550 Alexandre Duret-Lutz.
5552 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
5554 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
5555 and _LT_AC_TAGCONFIG.

5559 * doc/autoconf.texi (One Macro Call): Fix an incorrect
5560 example, and add more examples. Reported by Eric Sunshine.
5562 2004-01-05 Paul Eggert <eggert@twinsun.com>
5564 * doc/autoconf.texi (Limitations of Usual Tools):
5565 Remove warning against "rm -fr" introduced yesterday; it
5566 was a false alarm.
5568 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
5569 autoscan, autoupdate, ifnames): Don't use chmod -w.
5570 * lib/Makefile.am (autom4te.cfg): Likewise.
5571 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
5572 "chmod -w".

5575 Paolo Bonzini <bonzini@gnu.org>
5577 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
5578 by doing lineno substitution only on lines containing "$LINENO".
5580 2004-01-04 Paul Eggert <eggert@twinsun.com>
5582 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
5583 Use "rm -f" to remove conftest.sed, not plain "rm".
5584 Bug reported by David Relson in
5585 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
5587 * Makefile.am (autom4te-update):
5588 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
5589 * Makefile.maint (my-distcheck, do-po-update): Likewise.
5590 * doc/autoconf.texi (Guidelines): Likewise.

5596 * tests/Makefile.am (clean-local): Likewise.
5597 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
5598 srcdir): Likewise.
5599 * doc/autoconf.texi (Limitations of Usual Tools):
5600 Warn against "rm -fr".
5602 2004-01-03 Paul Eggert <eggert@twinsun.com>
5604 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
5605 -c -o might not work. From a suggestion by Kevin Ryde.
5606 (C Compiler, Generating Sources, Limitations
5607 of Usual Tools, Limitations of Make, Making testsuite Scripts):
5608 Don't put '-o' after non-options, as POSIX doesn't allow this.
5609 Mention that cc's name might be gcc or c89 or whatever.
5611 2004-01-04 Kevin Ryde <user42@zip.com.au>
5613 * doc/autoconf.texi: Add various further index entries.
5615 2003-12-29 Paul Eggert <eggert@twinsun.com>
5617 * bin/autoreconf.in (autoreconf_current_directory):
5618 Fix typo: mkdir without umask arg.
5620 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
5622 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
5623 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
5624 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
5625 explanation clearer.
5627 2003-12-24 Andreas Schwab <schwab@suse.de>
5629 * doc/autoconf.texi (Default Includes): Fix misspelling of
5630 AC_INCLUDES_DEFAULT.

5634 * configure.ac: Test if sh -n works.
5635 * configure: Regenerate.
5636 * tests/atlocal.in: Store the result here.
5637 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
5638 tools.at, looking in atlocal's ac_cv_sh_n_works instead
5639 of explicitly testing.
5640 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
5641 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
5642 * tests/tools.at (Syntax of the shell scripts): Simplify
5643 using AT_CHECK_SHELL_SYNTAX.

5657 Extracted from AS_SHELL_SANITIZE.
5658 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
5659 macros.
5660 (AS_SHELL_SANITIZE): Move reinvocation code from
5661 _AS_LINENO_WORKS, use it to find out if shell
5662 functions work.
5663 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
5664 does not work.
5665 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

5684 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

5712 parameter of AU_DEFUN.

5727 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
5728 than $target since the latter is not usual, add guidelines on when to

5877 Mention /usr/dt/bin/dtksh on Solaris.
5878 (Shell Substitutions): Warn about $((...)).
5879 (Parentheses): New section.
5881 2003-10-15 Kevin Ryde <user42@zip.com.au>
5883 * doc/autoconf.texi (Function Portability): Add @prindex for exit.
5884 Add putenv and unsetenv. Add sysconf _SC_PAGE_SIZE.
5886 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
5888 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
5889 cross test.
5891 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
5893 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
5894 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
5896 2003-10-10 Andreas Schwab <schwab@suse.de>
5898 * bin/autoheader.in: Avoid empty first line in --version and
5899 --help output.
5900 * bin/ifnames.in: Likewise.
5902 2003-10-09 Paul Eggert <eggert@twinsun.com>
5904 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
5905 Issue a more-informative diagnostic.
5906 Problems reported by Eric Sunshine.
5908 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5910 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
5911 -mGLOB_options_string stuff for Intel ifc, which can cause
5912 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
5913 pattern-matching instead of grep.
5915 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5917 * doc/autoconf.texi: Document new FC Fortran macros.
5919 2003-10-08 Gary V. Vaughan <gary@gnu.org>
5921 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
5922 that future autopoint/aclocal/automake/autoreconf will be able
5923 to trace to find where to install local m4 macros.
5924 * doc/autoconf.texi (Input): Document it.
5925 * NEWS: Updated.
5927 2003-10-06 Gary V. Vaughan <gary@gnu.org>
5929 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
5930 -lcrtbegin.o to list of ignored flags and fix underquoting of
5931 -lcrt[01].o.
5933 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
5935 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5936 cache variable instead of $G77 to decide whether to include -O2,
5937 since $G77 is specific to Fortran 77.
5939 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5941 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
5942 free" flag. Re-order flags tested into rough order of popularity.
5944 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5946 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
5947 arguments so that it can be used with syntax identical to
5948 AC_PROG_F77, and so that we can more easily decide to
5949 remove/deprecate the DIALECT optional argument in the future if it
5950 proves troublesome.
5951 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
5952 non-freeform-supporting compilers. Document freeform flags.
5954 2003-10-03 Akim Demaille <akim@epita.fr>
5956 * configure.ac: Look for emacs, not macs.
5957 Reported by Eric Sunshine.
5959 2003-10-03 Akim Demaille <akim@epita.fr>
5961 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
5962 * bin/autoreconf.in (autoreconf_current_directory): Create the
5963 AUX_DIR if needed, for sake of automake --add-missing etc.
5964 Suggested by Alexandre Duret-Lutz.
5966 2003-10-03 Akim Demaille <akim@epita.fr>
5968 * configure.ac: Quotation and formatting changes.
5969 (EMACS): Don't set it if it is not recent enough to support
5970 autoconf-mode.el.
5971 From Eric Sunshine.
5973 2003-10-02 Akim Demaille <akim@epita.fr>
5975 * bin/ifnames.in (&scan_file): Skip C++ comments.

5987 2003-09-30 Paul Eggert <eggert@twinsun.com>
5989 * lib/Autom4te/XFile.pm: Use Errno.
5990 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
5991 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
5993 2003-09-30 Akim Demaille <akim@epita.fr>
5995 * config/announce-gen (&print_news_deltas): Extracted from...
5996 (&print_changelog_deltas): here.
5997 (&news_file): Rename as...
5998 (@news_file): this.
6000 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
6002 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
6003 have been created when invoking the compiler.
6004 * tests/fortran.at (GNU Fortran 77): Quote $G77.
6006 2003-09-29 Akim Demaille <akim@epita.fr>
6008 Version 2.57e.
6010 * config/mkinstalldirs: Upgrade.
6012 2003-09-28 Paul Eggert <eggert@twinsun.com>
6014 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
6015 Problem reported by Lars J. Aas in
6016 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
6017 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6018 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6019 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6021 2003-09-26 Akim Demaille <akim@epita.fr>
6023 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6024 directory for AC_CONFIG_COMMANDS' first argument exists.
6025 This makes valid the invocation of _AC_SRCPATH that follows.
6026 Reported by Eric Sunshine.
6027 * doc/autoconf.texi (Configuration Commands): Adjust.
6029 2003-09-26 Akim Demaille <akim@epita.fr>
6031 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6032 Reported by Ralf Corsepius.
6034 2003-09-26 Akim Demaille <akim@epita.fr>
6036 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6037 arguments.
6038 Actually, use AU_ALIAS.
6039 From Bruno Haible.
6041 2003-09-26 Paul Eggert <eggert@twinsun.com>
6043 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
6044 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
6045 Problem reported by Eric Sunshine in:

6048 2003-09-26 Akim Demaille <akim@epita.fr>
6050 The test suite are sometimes assigning timings incorrectly.
6051 Reported by Henk Krus.
6052 Diagnosed by Nicolas Joly.
6054 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6055 AT_help_all.
6056 Instead of making AT_help a sequence of assignments to grow
6057 $at_help_all, just make AT_help_all be the growing contents of
6058 $at_help_all, and make a single assignment in...
6059 (AT_INIT): here.
6060 (at_times_skip): Flip the meaning and rename as...
6061 (at_times_p): this.
6062 (AT_INIT): When summarizing the test that ran, remove
6063 $at_times_file after use, and check it is present before trying to
6064 use it.
6066 2003-09-25 Akim Demaille <akim@epita.fr>
6068 Version 2.57d.
6070 * bin/Makefile.am (edit): Handle '@configure_input@'.
6071 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6072 (ifnames): chmod -w.
6073 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6074 executables, not bin/ executables! Otherwise all the magic needed
6075 to find non installed files is turned off. This caused a failure
6076 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6077 as found in its environment (sent by tests/autoreconf): pointing
6078 to bin/autom4te that could not find its files.
6079 * tests/mktests.sh: Force the replacement of generated files, for
6080 the sake of "mv" program that are interactive when overwriting a
6081 -w file.
6082 * config/install-sh: Upgrade from CVS Automake.
6084 2003-09-23 Paul Eggert <eggert@twinsun.com>
6086 * doc/autoconf.texi (Limitations of Builtins): Document test -h
6087 versus test -L issues.
6089 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
6090 Paul Eggert <eggert@twinsun.com>
6092 Trivial change to support GCC's configuration procedure.
6093 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6094 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6095 about inconsistency if the preprocessor is set to give errors for
6096 any warning.
6097 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6099 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
6101 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
6102 and XFile.pm from Automake.

6112 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
6113 from masters.
6115 2003-09-12 Akim Demaille <akim@epita.fr>
6117 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
6118 not asm/types.h.
6120 2003-09-11 Akim Demaille <akim@epita.fr>
6122 * doc/autoconf.texi (Header Portability): linux/random.h.
6123 From Peter Hendrickson.
6125 2003-09-10 Akim Demaille <akim@epita.fr>
6127 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6128 willing to edit the output files.
6130 2003-09-10 Akim Demaille <akim@epita.fr>
6132 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6133 and AC_FC_FREEFORM.
6134 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6135 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
6137 2003-09-09 Akim Demaille <akim@epita.fr>

6148 2003-09-07 Paul Eggert <eggert@twinsun.com>
6150 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
6151 Improve the accuracy of the wording about obsolescence.
6152 From a suggestion by Ian Lance Taylor in

6155 2003-09-05 Paul Eggert <eggert@twinsun.com>
6157 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6158 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6160 2003-09-04 Akim Demaille <akim@epita.fr>
6162 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6163 AC_FUNC_WAIT3.
6165 2003-09-04 Akim Demaille <akim@epita.fr>
6167 * bin/autom4te.in: Use &fatal where more appropriate than &error.
6168 (freeze): When exiting, use $exit_code.
6169 * lib/autoconf/fortran.m4: Comment changes.
6171 2003-09-04 Akim Demaille <akim@epita.fr>
6173 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
6175 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6177 Add support for newer Fortran dialects. The F77 interface is
6178 unchanged, and continues to support Fortran 77. New FC macros
6179 correspond to all the old F77 macros, with output variables FC,
6180 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6181 available dialect, but older dialects can be specified. There are
6182 new macros AC_FC_SRCEXT to set the source extension, and
6183 AC_FC_FREEFORM to accept free-form source files.
6185 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
6186 New macros.
6187 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
6188 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
6189 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
6190 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

6198 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
6199 AC_FC_SRCEXT, AC_FC_FREEFORM):
6200 New macros.
6201 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
6202 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
6203 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
6204 Rewrite in terms of the above.
6205 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
6206 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
6207 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
6208 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
6210 2003-09-02 Paul Eggert <eggert@twinsun.com>
6212 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
6213 Document problems with timestamp resolution that 'make', 'cp -p', and
6214 'touch -r' have.
6216 2003-08-27 Akim Demaille <akim@epita.fr>
6218 * tests/m4sugar.at (cross_warning): Make sure to enable the
6219 output, so that we can track spurious m4sugar output.
6220 * tests/local.at: Require 2.57.
6221 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
6222 are defaulted by AT_CHECK anyway.
6223 Use AT_CHECK_AUTOM4TE.
6224 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
6225 missing dnl.
6227 2003-08-27 Akim Demaille <akim@epita.fr>
6229 * bin/autoheader.in: Issue the "Using auxiliary..." message only
6230 when -Wobsolete is set.
6231 Set it on by default.
6232 Suggested by Klee Dienes.
6234 2003-08-27 Akim Demaille <akim@epita.fr>
6236 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
6237 documentation.
6238 From Guido Draheim.
6240 2003-08-26 Akim Demaille <akim@epita.fr>
6242 * doc/autoconf.texi (Output): Make clear that one can run code
6243 after AC_OUTPUT.
6245 2003-08-25 Akim Demaille <akim@epita.fr>
6247 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
6248 CVS Bison.
6250 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>

6264 2003-08-22 Akim Demaille <akim@epita.fr>
6266 Version 2.57b.
6268 * Makefile.cfg (local-checks-to-skip): New.
6269 * Makefile.maint (local-check): Rename as...
6270 (local-checks-available): this.
6271 (local-check): New.
6273 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
6274 * configure.ac: Require Automake 1.7.6.
6276 2003-08-22 Akim Demaille <akim@epita.fr>
6278 Output stack traces in warnings.
6280 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
6281 Replace the former...
6282 (m4_warn): Pass the call stack to _m4_warn.
6283 * bin/autom4te.in: Adjust to output the call stack.
6284 * tests/m4sugar.at (m4@&t@_warn): Adjust.
6286 2003-08-22 Akim Demaille <akim@epita.fr>
6288 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
6289 * bin/autom4te.in: Adjust.
6291 2003-08-21 Akim Demaille <akim@epita.fr>
6293 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
6294 (&verbose): Remove.
6295 (&getopt): Adjust the note and verb channels, depending upon
6296 --verbose.
6297 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
6298 * bin/autoupdate.in: Adjust.
6299 Use &verb, not &verbose.
6301 2003-08-21 Akim Demaille <akim@epita.fr>
6303 * bin/autoheader.in (&parse_args): Use &parse_warnings and
6304 &parse_WARNINGS.
6305 ($help): Use Autom4te::ChannelDefs::usage.
6306 * bin/autoscan.in: Use Autom4te::ChannelDefs.
6307 * lib/Autom4te/General.pm: Don't export error: you don't own it.
6309 2003-08-21 Akim Demaille <akim@epita.fr>
6311 First stab at preserving warnings between calls to autom4te,
6312 including when the cache is used.
6314 There are still several issues: (i) there are too many runs of m4
6315 (one for include, one for warnings, and some more), (ii) warnings
6316 spreading on several lines are not handled gracefully, (iii) the
6317 code meant to have the call stack display for errors does not work
6318 (its handling should move from m4 to autom4te).
6320 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6321 Use them.
6322 (@preselect): Add m4_warn.
6323 ($exit_status): Remove, use $exit_code.
6324 ($help): Use Autom4te::ChannelDefs::usage.
6325 (&handle_m4): No longer define the m4_warnings.
6326 At each run, extract and report the warnings.
6327 Always cache the result, including if the exit status is on
6328 failure, since if nothing changes, we should result in the same
6329 failure, hence we can use the cache.
6330 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6331 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6332 Remove.
6333 (m4_warn): Redefine as a do-nothing: it is its invocation that
6334 matters, as warnings are now reported via traces.
6335 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6336 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6337 the latter reveals calls to the former.
6339 Adjust the tests.
6341 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6343 2003-08-21 Akim Demaille <akim@epita.fr>
6345 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
6346 Use them.
6348 2003-08-21 Akim Demaille <akim@epita.fr>
6350 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
6351 forward order.
6352 * lib/Autom4te/ChannelDefs.pm: Doc typos.
6353 (&parse_warnings): Accept a list of warning requests.

6378 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
6379 (&xsystem, &contents): Remove, since they are exported by...
6380 * lib/Autom4te/FileUtils.pm: this.
6381 More perldoc.
6382 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
6383 * lib/Autom4te/FileUtils.pm: here.
6385 2003-08-20 Akim Demaille <akim@epita.fr>

6441 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
6442 shorter column three. Add DESCRIPTION to log file content.
6444 2003-08-13 Derek Price <derek@ximbiot.com>
6446 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
6447 output.
6449 2003-08-12 Derek Price <derek@ximbiot.com>
6451 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
6452 (AT_CHECK_NOESCAPE): Move core functionality to...
6453 (_AT_CHECK): ...this new macro.
6455 2003-08-07 Derek Price <derek@ximbiot.com>
6457 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
6458 (AT_CHECK_NOESCAPE): ...to this new macro.
6460 2003-07-31 Paul Eggert <eggert@twinsun.com>
6462 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
6463 in Bash 2.01. Problem reported by Brian Gough in
6464 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
6466 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
6468 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
6469 -lcrt1.o, for OS X. (trivial change)
6471 2003-07-07 Paul Eggert <eggert@twinsun.com>
6473 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
6474 inside '#ifndef __cplusplus'. Problem reported by
6475 Bob Friesenhahn.
6477 2003-07-06 Bill Clarke <llib@computer.org>
6479 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
6480 'long', not 'int', for benefit of Sun's recent C++ compilers
6481 (trivial change). See:
6482 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
6483 (This really should be 'intptr_t', not 'long', but that would
6484 take more work.)
6486 2003-06-25 Akim Demaille <akim@epita.fr>
6488 * lib/Makefile.am (autom4te.cfg): Make it read only.
6489 Depend on Makefile since it contains substitutions.
6490 From Paolo Bonzini.

6492 This change was made on autom4te.cfg which is generated.
6493 Reported by Raja R. Harinath.
6495 2003-06-25 Akim Demaille <akim@epita.fr>

6498 From Gareth McCaughan.
6500 2003-06-23 Akim Demaille <akim@epita.fr>
6502 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
6503 not all of them. This fixes 1. the fact that when testing
6504 Autoconf there are many many config.log, 2. the incorrect use of
6505 top_srcdir to find config.log.
6506 Don't mix the detailed output of failed test with the summary of
6507 failures. Rather, append detailed log afterwards.
6509 2003-06-23 Akim Demaille <akim@epita.fr>
6511 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
6512 always run: output config.log on $at_group_log.
6514 2003-06-23 Akim Demaille <akim@epita.fr>
6516 * tests/torture.at (#define header templates): Don't use quotes in
6517 C++ comments as it puzzles Emacs' sh font-lock-mode.
6519 2003-06-23 Akim Demaille <akim@epita.fr>
6521 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
6522 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
6523 * tests/atspecific.m4: Rename as...

6526 * tests/local.at: here.
6527 * tests/Makefile.am: Adjust.
6528 * doc/autoconf.texi (testsuite Scripts): Adjust.
6530 2003-06-21 Kevin Ryde <user42@zip.com.au>
6532 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
6533 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
6534 ensuring we add -std1 for full-ANSI.
6536 * doc/autoconf.texi (hdrindex): New macro.

6539 2003-06-20 Akim Demaille <akim@epita.fr>
6541 * configure.ac: Bump to 2.57b.
6543 2003-06-20 Akim Demaille <akim@epita.fr>
6545 Version 2.57a.
6547 2003-06-20 Akim Demaille <akim@epita.fr>
6549 * bin/autom4te.in: Don't rely on $HOME being defined.
6550 Reported by Marc Espie as PR/233.
6552 2003-06-20 Akim Demaille <akim@epita.fr>
6554 * lib/autotest/general.m4: Use at_times_file only if used.
6555 From Nicolas Joly.
6557 2003-06-20 Akim Demaille <akim@epita.fr>
6559 * config/config.guess, config/config.sub, config/elisp-comp,
6560 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
6561 Update from masters.
6563 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
6565 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
6566 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
6567 (TEST_SCRIPT): New diversion.
6568 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
6569 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
6570 (AT_INIT): Support for expected failures.
6572 2003-06-02 Akim Demaille <akim@epita.fr>
6574 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
6575 changes.
6576 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
6577 Autoconf nor Automake.
6578 (&contents): New, from Automake.
6579 PODify.
6581 2003-05-28 Paul Eggert <eggert@twinsun.com>
6583 * NEWS, doc/autoconf.texi (Particular Functions),
6584 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
6585 is the inverse of localtime.
6587 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
6589 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
6590 (handle_exec_errors): New function. Work around $! being
6591 altered by WEXITSTATUS.
6592 (xqx, xsystem): Use handle_exec_errors.
6594 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
6596 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
6597 Do not call `_exit()', simply modify `$?'.
6598 (xsystem): Reset $! before running system, and check it afterward.
6599 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
6600 63 for version mismatches.
6602 2003-05-23 Akim Demaille <akim@epita.fr>
6604 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
6605 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
6606 the middle of a line).
6607 * lib/m4sugar/m4sugar.m4: Likewise.
6608 Remove useless spaces in comments.
6610 2003-05-23 Akim Demaille <akim@epita.fr>
6612 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
6613 exit 63, so that we (or Automake's "missing") can tell the
6614 difference with a plain failure.
6615 * doc/autoconf.texi (Notices): Adjust.
6617 2003-05-23 Akim Demaille <akim@epita.fr>
6619 * Makefile.am, bin/Makefile.am, config/Makefile.am,
6620 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
6621 White spaces cleanup.
6623 2003-05-22 Jim Meyering <jim@meyering.net>
6624 Paul Eggert <eggert@twinsun.com>
6626 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6627 Remove `#include <stdlib.h>' from the list; we should never
6628 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6629 resulting namespace pollution would cause other tests to fail.
6630 Configure scripts run with some older versions of g++ and HP's
6631 aCC would fail due to such an #include. Problems reported by
6632 Matthew Mueller in <http://bugs.debian.org/120704> and by
6633 Keith Bostic in
6634 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6635 In the test, use the test declaration before including <stdlib.h>,
6636 as that's closer to how it'll be used.
6638 2003-05-23 Akim Demaille <akim@epita.fr>
6640 * doc/autoconf.texi (Header Portability): ucred.h.
6641 From Ian Redfern.
6643 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6645 Overhaul Autotest's logging: generate separate log files
6646 in testsuite.dir/NNN/testsuite.log, and append them to
6647 testsuite.log instead of re-running the test verbosely.
6649 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6650 file descriptor, write 0 to at_status_file instead of setting
6651 at_status=0, initialize some new variables (at_status_file,
6652 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6653 to rerun the tests, instead append the at_group_log to the
6654 at_suite_log when a test fails.
6655 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6656 with the AS_MESSAGE_LOG_FD redirected to stdout.
6657 (AT_CLEANUP): save the output status in $at_status_file
6658 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6659 its original place.
6660 (AT_CHECK): since tests are run with a redirected stdout,
6661 and used to be re-run in verbose mode, turn some $at_verbose
6662 into echo, and don't redirect the output of testing stdout
6663 and stderr.
6665 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6666 the name of the debugging directory and information about
6667 its contents.
6669 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6671 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
6672 parameter.
6674 2003-05-22 Akim Demaille <akim@epita.fr>
6676 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
6677 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
6678 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

6694 Whitespace clean up.
6695 Suggested by Jim Meyering.
6697 2003-05-22 Akim Demaille <akim@epita.fr>
6699 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
6700 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
6701 Reported by Jim Meyering.
6703 2003-05-22 Akim Demaille <akim@epita.fr>
6705 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

6709 From Art Haas.

6724 * bin/autoupdate.in ($m4): Fix quotation.

6727 2003-05-19 Paul Eggert <eggert@twinsun.com>
6729 * ChangeLog, ChangeLog.2, THANKS, lib/m4sugar/m4sugar.m4:

6736 AC_CHECK_HEADERS_NEW): New tests.
6738 2003-05-17 Akim Demaille <akim@epita.fr>
6740 * lib/autoconf/functions.m4: Use the default includes so that
6741 memcmp be declared before being tested.
6742 Reported by Sander Niemeijer.
6743 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
6744 * doc/autoconf.texi (Default Includes): Document
6745 AC_INCLUDES_DEFAULT.
6747 2003-05-17 Akim Demaille <akim@epita.fr>
6749 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
6750 * doc/autoconf.texi (Obsolete Macros): Adjust.
6751 Reported by Werner LEMBERG and Debian Bug 190886.
6753 2003-05-16 Akim Demaille <akim@epita.fr>
6755 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
6756 user name space clashes.
6757 Reported by Bruno Haible.
6759 2003-05-16 Akim Demaille <akim@epita.fr>
6761 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
6762 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
6763 them uniform, and more robust to Perl special characters.
6764 Reported by Martin Mokrejs.
6766 2003-05-14 Akim Demaille <akim@epita.fr>
6768 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.
6770 2003-05-14 Akim Demaille <akim@epita.fr>
6772 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,

6777 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
6778 message.
6779 From Matthias Andree.
6781 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
6783 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
6784 and truncate.
6786 2003-05-06 Akim Demaille <akim@epita.fr>
6788 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6789 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6790 by aclocal.m4 is changed it might require the importing of another
6791 m4 extension file, i.e., aclocal must be run.
6793 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6794 (&parse_args): Use --force with aclocal if required and supported.
6795 (&autoreconf_current_directory): Use &run_aclocal.
6797 2003-05-06 Akim Demaille <akim@epita.fr>
6799 Lock autom4te's cache.
6801 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
6802 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6803 argument instead of a file name, so that the request file remains
6804 open during the whole autom4te run.
6805 ($icache_file): New.
6806 (&freeze): Lock the $icache_file.
6808 2003-04-29 Derek Price <derek@ximbiot.com>
6810 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6811 seperator with m4_append_uniq(). It doesn't work.
6812 (AT_CLEANUP): Add `;' to end of at_help_all.
6813 (AT_INIT): Allow --keywords to be specified more than once. When
6814 grepping $at_help_all for keywords, use the field and keyword
6815 seperators to ensure a complete keyword match. Alter at_prev handling
6816 to support the new --keywords behavior.
6818 2003-04-27 Karl Berry <karl@freefriends.org>
6820 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6821 align better with others. I also made some of the individual
6822 entries on one line, for brevity and to make it easier for me to
6823 sort my dir-example file in the Texinfo distribution :).
6825 2003-04-12 Jim Meyering <jim@meyering.net>
6827 * NEWS: Mention the new macro.
6828 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.

6890 header causes problems.
6892 2003-03-28 Akim Demaille <akim@epita.fr>
6894 * tests/torture.at (Configuring subdirectories): Require aclocal
6895 1.4, otherwise the test fails, as it does support configure.ac.

6918 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
6919 obsolete AC_HELP_STRING.
6920 (AC_HELP_STRING): AU_DEFUN to...
6921 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
6922 * tests/m4sh.at (AS_HELP_STRING): New test.
6924 * tests/acgeneral.at: Regenerated.
6926 2003-03-26 Derek Price <derek@ximbiot.com>
6928 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
6929 sense. Verbosify the diversion definitions comment.

6969 (Automake): Automake 1.5+ no longer requires special tools to be
6970 present on the developer's host.
6972 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
6974 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
6975 to a shell that can handle redirection or quoting correctly.

6977 Use of $^O suggested by Tim van Holder.
6978 * bin/autom4te.in (BEGIN): Likewise.
6979 * bin/autoreconf.in (BEGIN): Likewise.
6980 * bin/autoscan.in (BEGIN): Likewise.
6981 * bin/autoupdate.in (BEGIN): Likewise.
6982 * bin/ifnames.in (BEGIN): Likewise.
6984 * bin/ifnames.in: Add final newline to help and version messages.
6986 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
6987 to cope with DOS-style absolute paths, when constructing
6988 ${ac_make}.
6990 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
6991 When constructing paths with IFS=:, quote the path. If we're
6992 constructing a DOS-style absolute path, we don't want to split it
6993 on the colon.
6995 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
6996 in description.
6998 2003-02-25 Pavel Roskin <proski@gnu.org>

7008 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
7010 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
7011 to fix a mismatch between example and discussion.
7013 2003-02-24 Kevin Ryde <user42@zip.com.au>
7015 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
7016 format starting with "-".
7018 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7020 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
7021 is not portable inside Makefile.
7023 2003-02-20 Akim Demaille <akim@epita.fr>
7025 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7026 compiler says yeah, but preproc says nope, compiler is right.
7027 Conversely, prompt the reader to send a bug report to the
7028 maintainers of the package, not of Autoconf.
7030 2003-02-20 Klee Dienes <kdienes@apple.com>
7032 * bin/autoreconf.in (autoreconf_current_directory): Properly
7033 handle an empty aclocal.m4.

7038 $ac_prefix_program.
7039 From Larry Jones.
7041 2002-12-23 Paul Eggert <eggert@twinsun.com>
7043 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7044 innocuous variant befor including <limits.h> or <assert.h>. This
7045 works around a bug reported by Albert Chin: HP-UX 11i
7046 (and earlier versions) have a <limits.h> that declares
7047 gettimeofday and many other functions.
7049 2002-12-03 Paul Eggert <eggert@twinsun.com>
7051 Version 2.57.
7053 * NEWS, configure.ac: Update version.
7055 * doc/fdl.texi: Upgrade to FDL version 1.2.
7057 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7058 nontrivially in main's body, so that f's external declaration is
7059 not optimized away in AIX. This should fix the bug reported by
7060 Martin Frydl in
7061 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7063 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7064 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7065 defined, to support freestanding compilers. This should fix the
7066 bug reported by Momchil Velkov in
7067 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7069 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7070 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
7071 obsolete AC_CHECK_TYPE. The missing empty arg was reported

7075 * Makefile.maint (www-gnu): New macro.
7076 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
7077 the location has moved.
7079 2002-12-02 Martin Frydl <martin@systinet.com>
7081 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
7082 \(.*\) match is too long and there is something more to be checked.
7083 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
7085 2002-11-15 Akim Demaille <akim@epita.fr>

7090 From Paul Eggert.
7091 * config/move-if-change: Indenting changes.
7092 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
7093 * configure.ac (AM_INIT_AUTOMAKE): here.
7094 Require 1.7.1.
7096 2002-11-14 Akim Demaille <akim@epita.fr>
7098 Version 2.55.
7100 * config/config.guess, config/config.sub, config/install-sh:
7101 Update from masters.
7103 2002-11-14 Akim Demaille <akim@epita.fr>
7105 * Makefile.maint: Sync with Bison, i.e.:
7106 (po-check): Scan .l and .y files instead of the
7107 .c and the .h files that they generate. This fixes the bug
7108 reported by Tim Van Holder in:
7109 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7110 Look for N_ as well as for _. Try to avoid matching #define for
7111 N_ and _.
7112 From Paul Eggert.
7114 2002-11-14 Akim Demaille <akim@epita.fr>
7116 * doc/autoconf.texi (C Compiler): Compiling several files at once.
7117 From Paul Eggert and Albert Chin-A-Young.
7119 2002-11-14 Akim Demaille <akim@epita.fr>
7121 * doc/autoconf.texi (C Compiler): Solitary backslashes.
7122 From Paul Eggert and Albert Chin-A-Young.
7124 2002-11-14 Kevin Ryde <user42@zip.com.au>
7126 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
7127 than assigning in main, to avoid HP cc +O3 optimizing it away.
7129 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
7131 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
7132 option. Process --recheck after parsing all options. Pass -q
7133 option to configure on --recheck.
7134 (AC_OUTPUT): Pass -q from configure to config.status.
7135 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
7136 arguments to record.
7137 * doc/autoconf.texi (config.status Invocation): Document
7138 config.status -q option.
7140 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
7142 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
7143 Makefile.in if Makefile.am exists.

7145 output AC_CONFIG_FILES if no Makefiles were found.
7147 2002-11-07 Akim Demaille <akim@epita.fr>

7154 2002-11-06 Akim Demaille <akim@epita.fr>
7156 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
7157 declaration in extern "C" too.

7160 2002-11-06 Akim Demaille <akim@epita.fr>
7162 * tests/torture.at (Configuring subdirectories): Don't use grep
7163 -w.
7164 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
7165 Reported by Ezra Peisach.
7167 2002-11-05 Akim Demaille <akim@epita.fr>
7169 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7170 Remove.
7171 We _have_ to stop using the old compatibility scheme that tried to
7172 avoid useless backslashes because Libtool 1.4.3 contains a
7173 AC_DEFINE([error_t], [int],
7174 [Define to a type to use for \`error_t' if it is not
7175 otherwise available.])
7176 We _have_ to quote the single quote and backslashes with \. The
7177 old compatibility scheme saw that ` was backslashed, and therefore
7178 did not quote the single quote. Hence before this patch, Autoconf
7179 was not compatible with Libtool.
7181 2002-11-04 Paul Eggert <eggert@twinsun.com>
7183 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

7188 2002-11-04 Akim Demaille <akim@epita.fr>
7190 Version 2.54c.
7192 * Makefile.maint (update, cvs-update, po-update, do-po-update):
7193 New.
7194 * config/texinfo.tex: Update.
7196 2002-11-03 Akim Demaille <akim@epita.fr>
7198 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
7199 from...
7200 (&autoreconf): here.
7201 ($help, $make, &parse_args, &autoreconf_current_directory):
7202 Support -m/--make.
7203 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7205 2002-10-31 Bruno Haible <bruno@clisp.org>
7207 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.

7218 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
7219 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
7221 2002-10-31 Akim Demaille <akim@epita.fr>
7223 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
7224 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
7225 Make variable, not a shell variable.
7226 Suggested by Bruno Haible.
7228 2002-10-31 Akim Demaille <akim@epita.fr>
7230 * bin/autom4te.in (load_configuration): Reject #args out of any
7231 language.
7233 2002-10-31 Akim Demaille <akim@epita.fr>
7235 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
7236 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
7237 (_AC_RUN_IFELSE): Use it.
7238 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
7239 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
7240 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
7241 inline it.

7247 Suggested by Tim van Holder.
7249 2002-10-29 Paul Eggert <eggert@twinsun.com>
7251 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
7252 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
7253 Problem reported by Bruno Haible.
7255 2002-10-29 Akim Demaille <akim@epita.fr>
7257 * doc/autoconf.texi (Header Templates): Put also in words what the
7258 pictures says to assist free style readers.
7259 (Customizing autom4te): s/--cache=/--cache /.
7261 2002-10-29 Akim Demaille <akim@epita.fr>
7263 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
7264 sys/wait.h.
7265 sparc_address_test returns void.
7266 Use it with an argument, as prototyped.
7267 From Bruno Haible.
7269 2002-10-29 Akim Demaille <akim@epita.fr>
7271 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

7277 * tests/torture.at (Deep Package): New test.

7283 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
7284 * doc/autoconf.texi (Invoking autom4te): Rename as...
7285 (autom4te Invocation): this, for consistency with the other nodes.
7287 2002-10-29 Akim Demaille <akim@epita.fr>
7289 * lib/autom4te.in (Autoconf): s/automate/autom4te/.
7290 Reported by Ralf Corsepius.

7296 Reported by Ralf Corsepius.
7298 2002-10-28 Akim Demaille <akim@epita.fr>
7300 * configure.ac: Bump to 2.54c.

7511 2002-10-22 Akim Demaille <akim@epita.fr>
7513 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

7516 Quote for Perl '' strings, not "".
7517 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
7518 strings.
7520 2002-10-22 Akim Demaille <akim@epita.fr>
7522 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

7569 longer required can still cause errors.
7570 Reported by Alexandre Duret-Lutz.
7572 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
7573 to frozen files in @ARGV, as @ARGV must remain being a list of

7575 (&files_to_options): New function.
7576 (&freeze): Use &error.
7577 (&up_to_date): If a file that was included according to the cache
7578 is no longer there, then the output is out dated.
7579 (&main): Don't even check whether a file is up to date is anyway
7580 --force is given.
7581 * tests/tools.at (autom4te cache): New.
7583 2002-10-16 Akim Demaille <akim@epita.fr>

7588 Factor some code.
7589 (&autoreconf): Report the directories we enter *and leave*, so
7590 that error messages can be easily located, and use GNU Make
7591 format, so that Emacs' compile mode understands us.
7592 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
7593 if some file was changed instead of `print'.
7594 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

7628 file name to enable parallel executions.
7629 From Sam Varshavchik.
7631 2002-10-08 Akim Demaille <akim@epita.fr>
7633 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7634 aclocal invocation, as Gettext macros might not be visible to
7635 aclocal.
7636 Instead of blindly running autopoint, scan configure.ac (not the
7637 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
7638 Reported by Paul D. Smith.
7640 2002-10-08 Paul Eggert <eggert@twinsun.com>
7642 Work around problems found when POSIXLY_CORRECT=1 is set.
7643 None of this seems to have anything to do with POSIX, really,
7644 but it's how Perl getopt works.
7645 * bin/autom4te.in (parse_args): Configure GetOpt with
7646 "permute", too.
7647 * doc/autoconf.texi (Invoking autom4te):

7670 * tests/torture.at (Configuring subdirectories): Be robust to
7671 users who use config.site to require for a cache: in this case,
7672 the two last configure runs, using two different sets of
7673 arguments, trigger a legitimate error.
7675 2002-09-28 Akim Demaille <akim@epita.fr>

7692 * lib/autoconf/types.m4: here, using AN_ macros.
7693 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
7694 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7695 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
7696 * lib/autoconf/programs.m4: here.

7710 tests/autom4te itself.
7711 * lib/autoscan/Makefile.am: Include freeze.mk.
7712 (autoscan.list): New target --this file is no longer a source.
7713 (autoscan.pre): New file.

7718 Adjust all uses.
7719 (&init_tables): When --debug, report the list of rules to ease
7720 tracking changes in autoscan.list.
7721 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7723 2002-09-28 Akim Demaille <akim@epita.fr>

7736 `functions' line is now prefixed with `function:'.
7737 * bin/autoscan.in (&init_tables): Adjust.
7739 2002-09-28 Akim Demaille <akim@epita.fr>
7741 From now on, autoscan files must always map a macro name to a
7742 word: there is no `default' macro for autoscan.
7744 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7745 all.
7746 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7747 explicit.
7749 2002-09-28 Akim Demaille <akim@epita.fr>
7751 * bin/autoscan.in (%c_keywords): Remove.

7785 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7787 2002-09-26 Akim Demaille <akim@epita.fr>
7789 Single suffix rules and seperated dependencies are not portable.

7833 2002-09-13 Akim Demaille <akim@epita.fr>
7835 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
7836 reading config.log when the compiler is rejected.
7837 Suggested by Guido Draheim.
7839 2002-09-13 Akim Demaille <akim@epita.fr>
7841 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
7842 (chdir_init) might hang when stat'ing mounted directories.
7843 Reported by Vance Shipley.
7845 2002-09-12 Akim Demaille <akim@epita.fr>
7847 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7848 the lists.
7850 2002-09-12 Akim Demaille <akim@epita.fr>
7852 * doc/autoconf.texi (Defining Symbols): Present two different
7853 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
7854 difference between 1 argument calls, and 2-3 argument calls.
7856 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
7858 * doc/autoconf.texi: Review grammar and punctuation.
7860 2002-09-11 Paul Eggert <eggert@twinsun.com>
7862 * doc/autoconf.texi: Fix minor formatting, spelling, and
7863 grammatical typos.
7864 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7865 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7866 is obsolescent.
7868 2002-09-11 Akim Demaille <akim@epita.fr>
7870 * doc/autoconf.texi (Questions): Rename as...
7871 (FAQ): this.
7872 (Defining Directories): New.
7874 2002-09-09 Akim Demaille <akim@epita.fr>
7876 * doc/autoconf.texi (Making testsuite Scripts): Update.
7877 Suggested by Nishio Futoshi.
7879 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
7881 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
7882 plain `@' is wanted.
7884 2002-09-09 Akim Demaille <akim@epita.fr>
7886 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7887 `duplicates', since the algorithm was too naive and could keep
7888 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7889 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7890 Reported by Ralf Corsepius.
7891 * tests/torture.at (Configuring subdirectories): Exercise these
7892 cases.
7894 2002-09-09 Akim Demaille <akim@epita.fr>
7896 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
7897 looking for a replacement file.
7898 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7899 directory is relative.
7900 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7901 directory definition.
7902 Reported by Andreas Schwab and Jim Meyering.
7904 2002-09-06 Akim Demaille <akim@epita.fr>
7906 * doc/autoconf.texi (Setting Output Variables): Clarify what
7907 precious variables are.
7908 Suggested by Pontus Skoeld.
7910 2002-09-05 Akim Demaille <akim@epita.fr>
7912 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7913 (ifnames, autoscan, autom4te): Since we don't only depend on
7914 configure.ac variables (such as VERSION etc.), but also on prefix
7915 and so forth, depend on Makefile, not configure.ac.
7916 Reported by Alexandre Duret-Lutz.
7917 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7919 2002-09-05 Kevin Ryde <user42@zip.com.au>
7921 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7922 doesn't seem to be confined to ia64, just say "some versions".
7924 2002-09-04 Akim Demaille <akim@epita.fr>
7926 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
7927 Automake 1.6c.
7928 * Makefile.am (maintainer-clean-local): Remove.
7929 (MAINTAINERCLEANFILES): Remove COPYING.
7931 2002-09-03 Paul Eggert <eggert@twinsun.com>
7933 * doc/autoconf.texi (Configuration Commands): Remove obsolete
7934 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
7935 Brinkmann.
7937 2002-09-03 Akim Demaille <akim@epita.fr>
7939 * configure.ac: Bump to 2.53d.
7940 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
7941 as of today, on Automake's team suggestion.
7943 2002-09-03 Akim Demaille <akim@epita.fr>
7945 Version 2.53c.
7947 2002-09-02 Akim Demaille <akim@epita.fr>
7949 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7950 SITE_MACRO_DIR.
7951 * configure.ac: Disable SITE_MACRO_DIR.
7953 2002-09-02 Jim Meyering <meyering@lucent.com>
7955 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7956 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7957 Also, tweak grammar: s/make sure to/be sure to/.
7959 2002-09-02 Paul Eggert <eggert@twinsun.com>
7961 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7962 directory names are generally preferable to physical names.
7964 2002-09-02 Akim Demaille <akim@epita.fr>
7966 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7967 Reported by Raja R. Harinath.
7968 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7969 * bin/autoupdate.in: Use error instead of die.
7971 2002-09-01 Paul Eggert <eggert@twinsun.com>
7973 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7974 ordinary shell concatenation rather than echo+tr+sed command that
7975 runs afoul of a long-line-related sed bug in Solaris 8.
7977 * bin/autoheader.in (parse_args): --warning -> --warnings.
7979 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7980 stdout, as traditional "ls" does.
7981 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7982 _AC_COMPILER_EXEEXT_O): Likewise.
7983 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7985 * bin/autoconf.as: Add --prepend-include option. This patch was
7986 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7987 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7989 * bin/autoconf.in, configure: Regenerate.
7991 * doc/autoconf.texi (Special Shell Variables): Mention
7992 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7994 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7995 MAILPATH and set PS1, PS2, PS4 to default values, to work
7996 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7997 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7998 the Autoconf documentation specifies; fall back to "unset" only if
7999 this fails. Use a shell for-loop for this rather than an m4 loop,
8000 to shorten the output script.
8002 2002-08-30 Paul Eggert <eggert@twinsun.com>
8004 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8005 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8006 for the CDPATH problem. Document PWD.
8007 (Limitations of Builtins): Document the problem that "cd $foo" and
8008 "ls $foo" may refer to different directories in shells conforming
8009 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8010 example, since the old example is now out of date.
8012 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8013 FOO" and "ls FOO" talk about different directories; this catches
8014 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8015 spaghetti.
8017 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8018 of rolling our own unset.
8019 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8020 in practice we needn't worry about CDPATH if unset doesn't work.
8022 * Makefile.in, aclocal.m4, bin/Makefile.in,
8023 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8024 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8025 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8026 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8027 tests/Makefile.in: Regenerate with Automake 1.6.3.
8029 * config/config.guess, config/config.sub, config/mkinstalldirs:
8030 Update.
8032 * configure: Regenerate with self.
8034 2002-08-30 Kevin Ryde <user42@zip.com.au>
8036 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8037 default output.
8039 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8041 * bin/autom4te.in (Request::load): Correctly test for "do" read
8042 failure.
8044 2002-08-29 Akim Demaille <akim@epita.fr>
8046 * lib/Autom4te/General.pm (&xqx): New.
8047 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8048 hand, which is not portable.
8049 (&error): New.
8050 * bin/autom4te.in: Use them.
8051 Use &error instead of die.
8052 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8053 Adjust.
8055 2002-08-17 Paul Eggert <eggert@twinsun.com>
8057 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8058 default list of compilers to try, since it was long ago superseded
8059 by the ksh fc builtin. Suggested by Steven G. Johnson.
8061 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8063 * doc/autoconf.texi (Invoking autom4te): End the option table,
8064 fixing a bug introduced by the previous patch.
8065 (Limitations of Make): Add a 'target lookup' subentry in the
8066 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8068 2002-07-29 Mark D. Roth <roth@feep.net>
8070 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8071 options and use $AUTOM4TE_PATH.
8072 * doc/autoconf.texi: Remove documentation of autom4te
8073 --include-envvar and --site-macro-subdir options and document
8074 use of $AUTOM4TE_PATH.
8075 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8076 arguments from each language section.
8078 2002-07-29 Paul Eggert <eggert@twinsun.com>
8080 * doc/install.texi: Include copyright symbol in copyright notice.
8082 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8083 Replace with:
8084 (AM_MAKEINFOFLAGS): New macro.
8085 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8086 * Makefile.am (INSTALL): Use the new macros.
8087 Use -o rather than --output, since "missing" does not grok --output.
8089 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8091 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8092 comments do not always work. Never trust the exit status of
8093 `make -k'.
8095 2002-07-24 Kevin Ryde <user42@zip.com.au>
8097 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8098 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8100 2002-07-23 Paul Eggert <eggert@twinsun.com>
8102 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8103 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8104 apparently treats PATH="nonexistent" as if it contained ".".
8105 Bug reported by Stefan `Sec' Zehl.
8107 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8109 * doc/autoconf.texi (Limitations of Make): Mention the special
8110 handling of the obj/ directory by BSD make.

8126 2002-07-18 Akim Demaille <akim@epita.fr>
8128 Version 2.53b.
8130 2002-07-18 Akim Demaille <akim@epita.fr>
8132 * config/config.guess, config/config.sub: Update.
8134 2002-07-18 Akim Demaille <akim@epita.fr>

8144 Alexandre Duret-Lutz <duret_g@epita.fr>
8146 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install

8152 description of the tarname default.

8156 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
8157 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
8158 latter was not run.
8160 2002-07-17 Akim Demaille <akim@epita.fr>
8162 * lib/Autom4te/General.pm (find_file): Browse the directories in
8163 the order they are given.

8183 macro directory, remove note that include path directories are
8184 used in reverse order, and document --prepend-include option.
8185 * lib/autom4te.in: Use --prepend-include instead of --include.
8186 * tests/wrapsh.in: Use --prepend-include instead of --include.
8188 2002-07-17 Akim Demaille <akim@epita.fr>

8243 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
8244 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
8245 so that we consistently test the just-built programs.
8246 * tests/wrappl.as: Likewise.
8248 2002-06-12 Paul Eggert <eggert@twinsun.com>
8250 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

8254 * bin/autoreconf.in (autoconf, autoheader): Likewise.
8255 * bin/autoscan.in (autom4te): Likewise.

8258 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
8259 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
8260 on Solaris 2.5.1.
8262 2002-06-11 Andreas Schwab <schwab@suse.de>
8264 * doc/autoconf.texi: Add more dir entries.
8266 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
8268 * bin/autom4te.in ($cache): Don't define using `$me', the name
8269 of the cache should not depend on the name under which autom4te
8270 was installed.
8272 2002-06-07 Akim Demaille <akim@epita.fr>
8274 * tests/tools.at (autoconf: forbidden tokens, basic)
8275 (autoconf: forbidden tokens, exceptions): Adjust to the change of
8276 words in autom4te.in.
8278 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
8280 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
8281 _AC_LANG_PROGRAM_C_F77_HOOKS.
8283 2002-06-07 Akim Demaille <akim@epita.fr>

8320 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
8321 if ln doesn't work.
8322 * NEWS: Likewise.
8323 * doc/autoconf.texi (Configuration Links): Likewise.
8324 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
8326 2002-06-05 Paul Eggert <eggert@twinsun.com>
8328 * config/config.guess, config/config.sub, config/texinfo.tex:
8329 Update from masters.
8331 2002-05-29 Paul Eggert <eggert@twinsun.com>
8333 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
8334 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
8335 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):
8336 Likewise.

8343 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
8344 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
8346 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
8347 * doc/autoconf.texi (Particular Programs): Document them.
8348 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
8349 * NEWS: Likewise.
8351 2002-05-27 Paul Eggert <eggert@twinsun.com>
8353 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
8354 * NEWS, doc/autoconf.texi (Particular Types): Document it.
8355 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
8356 instead of AC_MBSTATE_T, which never existed.
8358 2002-05-23 Akim Demaille <akim@epita.fr>
8360 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
8361 version of Autoconf that is discussed.
8363 2002-05-22 Paul Eggert <eggert@twinsun.com>
8365 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
8366 from the default list of compilers to try. Suggested by
8367 Kate Hedstrom.
8368 * NEWS: Document the above.
8369 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
8371 2002-05-17 Paul Eggert <eggert@twinsun.com>
8373 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
8374 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
8375 This improves on an earlier suggestion by H. Peter Anvin.
8377 2002-05-16 Paul Eggert <eggert@twinsun.com>
8379 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
8380 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
8381 Both macros now accept an optional source-dir arg.
8382 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
8384 * NEWS: Document this.
8385 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
8387 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
8388 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
8389 not for GNU extensions; this undoes part of the 2000-11-03 change,
8390 reverting to 2.13-compatible behavior.
8391 Add new optional argument DIR.
8392 (AC_FUNC_FNMATCH_GNU): New macro.
8394 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
8396 2002-05-08 Paul Eggert <eggert@twinsun.com>
8398 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
8399 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
8400 and it causes a 'test' syntax error if it fails.
8401 Bug reported by Stephen Gildea.
8403 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8404 If prototypes are supported, use them to check this at compile-time,
8405 instead of trying to check it at run-time. If we must do a run-time
8406 check, assume that setvbuf is standard when cross-compiling, as
8407 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8408 Bug reported by Paul D. Smith.
8410 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8411 argument specifying location of getloadavg.c. This removes a
8412 FIXME. This idea was taken from Jim Meyering's implementation in
8413 textutils.
8414 * doc/autoconf.texi (Particular Functions): Document this.
8415 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8416 that's what the code does; this fixes a bug reported by
8417 Paul D. Smith.
8419 2002-05-03 Akim Demaille <akim@epita.fr>
8421 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8422 autopoint instead of gettextize.
8423 ($uses_alocal): Rename as...
8424 ($uses_aclocal): this.
8425 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8426 Suggested by Bruno Haible.
8428 2002-05-03 Akim Demaille <akim@epita.fr>
8430 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
8432 2002-04-29 Paul Eggert <eggert@twinsun.com>
8434 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
8435 files to be 1 second older; just set them to be the same time.
8436 Also, sleep 1 second after the first aclocal, to work around
8437 problems with sub-second time stamps on the input files.
8439 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
8441 * doc/autoconf.texi: Mention "set -e -x" lossage
8442 under node "Limitations of Builtins".
8444 2002-04-29 Akim Demaille <akim@epita.fr>
8446 * doc/install.texi: Better wording for setting variables when
8447 running configure.
8448 From Christian Cornelssen.
8450 2002-04-29 Akim Demaille <akim@epita.fr>
8452 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
8453 of lack of $LINENO support, then the test will compare the $LINENO
8454 in testsuite vs. the lineno in the test file. This is wrong, of
8455 course.
8456 Be sure to protect it.
8457 Reported by Patrick Welche.
8459 2002-04-25 Akim Demaille <akim@epita.fr>
8461 * doc/autoconf.texi (Obsolete Macros): Typo.
8462 Reported by Vladimir Volovich.
8464 2002-04-25 Akim Demaille <akim@epita.fr>
8466 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
8467 than some of the input files, hence, on the second run of aclocal,
8468 if some of its input are younger, make them older.
8469 Suggested by Paul Eggert.
8471 2002-04-25 Akim Demaille <akim@epita.fr>
8473 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
8474 Thanks to Paul Eggert.
8476 2002-04-25 Akim Demaille <akim@epita.fr>
8478 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
8479 and ac_subst_vars be sh variables containing the list of
8480 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
8481 DEFAULT diversion.
8482 (_AC_INIT_PREPARE): Use them to log them.
8483 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
8484 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
8485 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
8486 _AC_SUBST_FILES and _AC_SUBST_VARS.
8487 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
8489 2002-04-24 Akim Demaille <akim@epita.fr>
8491 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
8492 autoheader, so that automake does not complain about a missing
8493 config.h.in that was to be created.
8495 2002-04-23 Akim Demaille <akim@epita.fr>
8497 * bin/autoheader.in (parse_args): --warning takes an argument.
8498 Fixes PR/220.
8500 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
8502 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
8503 and bb.out when cleaning up.
8505 2002-04-22 Akim Demaille <akim@epita.fr>
8507 Version 2.53a.
8509 2002-04-22 Akim Demaille <akim@epita.fr>
8511 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
8513 2002-04-22 Akim Demaille <akim@epita.fr>
8515 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
8516 comma.
8517 Reported by Gregory Giannoni.
8519 2002-04-22 Akim Demaille <akim@epita.fr>
8521 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
8522 Fixes false failures on Darwin.

8528 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

8547 Minor spelling and grammar fixes.
8549 * doc/autoconf.texi: Follow the outline suggested in the GNU
8550 Sample Texts sections of the Texinfo 4.2 manual. Most
8551 importantly, this makes sure that the copyright notices appear in
8552 all output formats. You probably need Texinfo 4.2 to generate
8553 the manual now.
8555 Fix some bugs when using "$@" when there might be zero positional
8556 arguments in cases where this matters.

8576 * tests/c.at: We can't have zero arguments, so remove workaround
8577 that is not portable to Zsh.
8579 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
8581 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
8582 from aclocal.m4 too.
8584 2002-04-12 Akim Demaille <akim@epita.fr>
8586 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
8588 2002-04-10 Akim Demaille <akim@epita.fr>
8590 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
8591 workaround for ${1+"$@"}.
8592 * doc/autoconf.texi (Shell Substitutions): Explain it.
8593 From Oliver Kiddle and Peter Stephenson.
8595 Have M4sh perform minimal shell sanitizing.
8597 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
8598 part into...
8599 (_AS_PREPARE): this new macro.
8600 (AS_PREPARE): New.
8601 (AS_INIT): Invoke AS_SHELL_SANITIZE.
8602 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
8604 Adjust Autoconf and Autotest.
8606 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
8607 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
8608 * lib/autotest/general.m4 (AT_INIT): Likewise.
8609 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8610 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
8611 AS_SHELL_SANITIZE.
8613 Use this M4sh to generate Autoconf's shell scripts.
8615 * tests/wrapsh.as: New, precursor of wrapsh.in.
8616 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
8617 on Autotest and M4sh.
8618 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
8619 (wrapsh.in): New target.
8620 * bin/autoconf.as: New, precursor of autoconf.in.
8621 (autoconf.in): New target.
8623 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

8626 with indented comments in rules.
8628 2002-04-09 Andreas Schwab <schwab@suse.de>
8630 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
8631 ac_top_builddir when setting ac_abs_top_builddir.
8633 2002-04-06 Kevin Ryde <user42@zip.com.au>
8635 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
8636 (Portable Shell): Cross reference to Systemology.
8638 2002-04-05 Akim Demaille <akim@epita.fr>
8640 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
8641 directories when descending in a SUBDIRS.
8642 Reported by Ezra Peisach.
8644 2002-04-04 Andreas Schwab <schwab@suse.de>
8646 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
8647 contains no literal separators.
8649 2002-04-03 Akim Demaille <akim@epita.fr>
8651 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
8652 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
8653 Use dnl, not the KILL diversion.
8654 Extracted from...
8655 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8656 (AC_CONFIG_LINKS): here.
8657 Adjust.
8658 Don't use the KILL diversion, as it kills spurious output, which
8659 results in failures being hidden.
8660 Use m4_defn where appropriate.
8661 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8662 after the second argument.
8663 Use m4_defn.
8664 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8665 syntax, as it is provided by M4sugar.
8666 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
8668 2002-04-03 Andreas Schwab <schwab@suse.de>
8670 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not

8674 aclocal.

8681 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
8682 (_AC_COMPILER_OBJEXT): Use them.
8683 Fixes Debian #138666.
8685 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
8687 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
8689 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
8690 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
8691 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
8692 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
8693 (AC_C_CONST): Same.

8698 AC_C_CROSS.

8703 _AS_MKDIR_P_PREPARE.
8705 2002-03-28 Kevin Ryde <user42@zip.com.au>
8707 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
8708 to avoid versions of HP C which don't allow that.
8710 2002-03-27 Paul Eggert <eggert@twinsun.com>
8712 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
8713 (AS_SHELL_SANITIZE): Invoke it.
8714 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

8724 2002-03-25 Paul Eggert <eggert@twinsun.com>
8726 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
8727 as POSIX requires, as it doesn't work with Zsh.
8728 * doc/autoconf.texi (Assignments): Document the problem.
8730 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8732 * doc/autoconf.texi (Limitations of Make): Mention more issue
8733 about VPATH, overriding of macros in sub-makes, and handling of
8734 SHELL.
8736 2002-03-21 Paul Eggert <eggert@twinsun.com>
8738 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8739 problem with here-document buffer boundaries.
8741 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8742 when reinvoking the shell, to work around problems with installers
8743 who put strange things like "cd" commands in their environments.
8745 2002-03-19 Akim Demaille <akim@epita.fr>
8747 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
8748 From Aaron Ucko.
8750 2002-03-19 Akim Demaille <akim@epita.fr>

8753 invocations.
8754 From Nicolas Joly.
8756 2002-03-19 Akim Demaille <akim@epita.fr>
8758 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
8759 From Nishio Futoshi.
8761 2002-03-19 Akim Demaille <akim@epita.fr>
8763 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
8765 2002-03-18 Paul Eggert <eggert@twinsun.com>
8767 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8768 (Limitations of Usual Tools): Add mkdir section.
8770 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8771 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8772 back on AS_DIRNAME to compute prefixes otherwise; this is
8773 roughly what mkinstalldirs does. That way, we need not have
8774 our own filename disassembler. The old disassembler did not
8775 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8777 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8778 Create at_test_all by a series of assignments,
8779 not by a single assignment of a long string. The latter causes ksh
8780 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8781 presumably because of a buffer overrun.
8783 2002-03-14 Paul Eggert <eggert@twinsun.com>
8785 * lib/autotest/general.m4 (at_times_skip):
8786 Renamed from at_times. Now a boolean.
8787 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8788 says 'times: not found'.
8790 2002-03-14 Akim Demaille <akim@epita.fr>
8792 * bin/autoreconf.in (&study_gettextize): New.
8793 (&autoreconf): Handle newest gettextize.

8795 Suggested by Andreas Schwab.
8797 2002-03-13 Akim Demaille <akim@epita.fr>
8799 * doc/autoconf.texi (Special Shell Variables): More about IFS.
8801 2002-03-13 Akim Demaille <akim@epita.fr>
8803 * doc/autoconf.texi (Header Portability): New.

8815 m4_require.
8817 2002-03-11 Andreas Schwab <schwab@suse.de>

8820 does not do it if --with-lispdir is given.
8822 2002-03-08 Akim Demaille <akim@epita.fr>
8824 Version 2.53.
8826 2002-03-08 Akim Demaille <akim@epita.fr>

8837 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8838 aliases the actual variables, and modifications of the former
8839 affect the latter.
8841 2002-03-08 Akim Demaille <akim@epita.fr>
8843 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8844 because of C-c: have m4 output in tmp files, then mv them.

8874 parallel builds.
8876 2002-03-04 Akim Demaille <akim@epita.fr>
8878 * doc/autoconf.texi (Transforming Names): Equality between target
8879 and host is irrelevant.
8880 (Specifying Names, Canonicalizing): Remove all references to the
8881 backward compatibility hooks. Rather, collect them all into...
8882 (Hosts and Cross-Compilation): this new section.
8883 * doc/install.texi (System Type): Ditto.
8884 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8885 that `--host' implies cross-compilation.
8887 2002-03-04 Akim Demaille <akim@epita.fr>
8889 * doc/autoconf.texi (Evaluation Macros): New.
8890 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8891 useless.
8892 (_m4_foreach): Define the variant with immediate evaluation so
8893 that it contains exactly the items, not an expression which
8894 evaluation is the current item.
8895 (m4_re_string, m4_re_word): Don't over quote them.
8897 2002-03-04 Akim Demaille <akim@epita.fr>
8899 Instead of having stacking `shift's evaluated at the end, let
8900 `foreach' loops immediately evaluate them.
8902 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8903 $*. This is the n-th time I change my mind, but hopefully this is
8904 the last...
8905 (m4_lquote): New.
8906 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8907 efficient.
8908 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8909 it was only a hack for m4_text_wrap.
8910 (m4_car2): Remove, replaced by...
8911 (m4_cdr): New.
8912 (_m4_foreach): Adjust.
8913 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8914 m4_bpatsubst for clarification.
8916 2002-03-04 Akim Demaille <akim@epita.fr>

8942 2002-02-25 Akim Demaille <akim@epita.fr>
8944 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
8945 From Akinori Musha.

8949 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
8950 translate \r\n to \n.

8984 2002-02-06 Akim Demaille <akim@epita.fr>
8986 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
8987 sure not to introduce newlines in at_groups.

8990 2002-02-06 Akim Demaille <akim@epita.fr>
8992 * tests/torture.at (Configuring subdirectories): Skip if aclocal
8993 is not available.

8998 Describe HP-UX cc bug workaround more accurately.

9000 not unsigned long.
9001 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9002 cross-compilers, too. This undoes some of the most recent change
9003 to this file.
9005 2002-02-05 Akim Demaille <akim@epita.fr>
9007 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

9019 2002-02-05 Akim Demaille <akim@epita.fr>
9021 Implement `autom4te --freeze'.

9024 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9025 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9027 2002-02-05 Akim Demaille <akim@epita.fr>
9029 * bin/autom4te.in (&parse_args): Implement `frozen files are
9030 optional are the sum of the previous files on the command line'.
9031 Also, pass `--reload-state=' on them, so...
9032 (handle_m4): don't.
9033 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9034 (M4sh): Rely on M4sugar.
9035 (Autotest, M4sh, M4sugar): Use frozen files.
9037 2002-01-31 Akim Demaille <akim@epita.fr>

9044 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9045 alphanumeric to `-' instead of `_'.
9047 2002-01-30 Akim Demaille <akim@epita.fr>
9049 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9050 for plain code, the other for cross-compilation code. The latter
9051 is now run with GCC only.

9059 change AC_INIT default values.
9061 2002-01-29 Akim Demaille <akim@epita.fr>
9063 * tests/torture.at (Configuring subdirectories): Use configure.in,
9064 so that aclocal 1.4 works.
9065 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9067 2002-01-28 Akim Demaille <akim@epita.fr>
9069 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9070 needs an argument.
9072 2002-01-28 Akim Demaille <akim@epita.fr>
9074 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9075 AUTOTEST_PATH *after* it was set.
9076 Don't put `.' in the PATH: the user should be precise and `./' if
9077 needed. In addition, given that the test suite does some `cd', if
9078 `.' is in the path, the `tested programs' sections will report
9079 programs found in the test suite's directory, while during the
9080 tests (performed in their own directory), these programs are no
9081 longer visible. In other words, the results is confusing and
9082 useless.
9083 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9085 2002-01-24 Akim Demaille <akim@epita.fr>

9097 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
9098 Bourne. Use /bin/sh.
9099 From Andreas Buening.

9125 2002-01-21 Akim Demaille <akim@epita.fr>
9127 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
9128 message on invalid options.
9129 * bin/autom4te.in (parse_args): Don't use
9130 Autoconf::General::getopt with non valid options.
9132 2002-01-17 Jim Meyering <meyering@lucent.com>
9134 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
9135 $ac_cv_exeext so we don't use an old, invalid, cached value.
9137 2002-01-11 Akim Demaille <akim@epita.fr>
9139 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim

9149 package.m4, since is really depends upon configure.ac, not
9150 configure.
9151 * doc/autoconf.texi (testsuite Scripts): Adjust.
9152 * tests/Makefile.am (package.m4): New.
9153 EXTRA_DIST it since its a source.
9155 2002-01-06 Akim Demaille <akim@epita.fr>
9157 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9158 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9159 and PACKAGE_BUGREPORT from here...
9160 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9161 arguments.
9162 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
9163 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
9164 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
9165 * tests/tools.at (autoheader): Adjust.
9166 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
9168 2002-01-06 Akim Demaille <akim@epita.fr>

9187 2001-12-14 Akim Demaille <akim@epita.fr>
9189 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9190 trailing files, don't apply `-rf' to files which might not be
9191 created by configure (core, core.*, and *.core), but just `rm -f'.
9192 Suggested by Jonathan Kamens.
9194 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9196 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

9200 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
9202 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

9230 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
9231 Remove $filepath, useless.
9232 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
9233 variables, they are really part of the tokens.
9234 Split the input line on spaces and then look for tokens.
9235 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9236 because of `lex$U.$(OBJEXT)'.
9237 (&scan_files): Use "@list" instead of join.
9238 * doc/Makefile.am (CLEANFILES): Add *.fns.
9240 2001-11-26 Akim Demaille <akim@epita.fr>

9243 Remove, replaced by...

9245 In particular autoscan and autoheader want -I.
9246 * configure.ac: Adjust.

9282 top_srcdir, builddir and top_builddir.

9301 spotted by Jim Meyering.
9303 2001-11-16 Paul Eggert <eggert@twinsun.com>
9305 This patch implements a `long double' suggestion by Oliver Kiddle.
9307 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9308 static, to catch errors if the value isn't known at compile-time
9309 and the compiler supports dynamic arrays. Change its name from
9310 `_array_' to `test_array' to avoid potential name clashes.
9311 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9312 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9313 better than double. Catch a bug in GCC 2.95.2 x86.
9314 * doc/autoconf.texi (C Compiler): Document the above.
9315 * NEWS: Likewise.
9317 2001-11-13 Akim Demaille <akim@epita.fr>
9319 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9320 hand.
9321 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9323 2001-11-13 Akim Demaille <akim@epita.fr>
9325 * lib/autotest/general.m4 (AT_INIT): After having run the test
9326 group, go back to the initial directory, not to at_suite_dir.
9328 2001-11-13 Akim Demaille <akim@epita.fr>
9330 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9331 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9332 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9333 option.
9334 (AT_CHECK_CONFIGURE): Use absolute paths.
9335 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9336 The problem is still the old one: there is no means in M4 (that I
9337 know about) to create a defining macro, because there is no means
9338 to create `$1' etc., therefore, the defining macro ``swallows''
9339 all the arguments meant to the defined macro.
9341 2001-11-13 Akim Demaille <akim@epita.fr>
9343 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9344 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9345 configure.ac.
9346 * tests/aclocal.m4: Remove, as it is no longer used.
9348 2001-11-13 Akim Demaille <akim@epita.fr>
9350 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9351 variable names when referring to a single test group, or to
9352 `suite' when referring to the whole test suite.
9353 `at_last_test' is removed: m4 compute at_format itself.
9354 (at_stdout, at_stder1, at_stderr): New variables.
9355 (AT_CHECK): Use them.
9357 2001-11-13 Akim Demaille <akim@epita.fr>
9359 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9360 in PATH.
9361 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9362 Do it as soon as a test fails, don't wait till the end of the test
9363 suite.
9364 Don't remove $as_me.[0-9]*, since these files no longer exist.
9366 2001-11-13 Akim Demaille <akim@epita.fr>
9368 * tests/tools.at: Use absolute paths, since we are no longer run
9369 in place.
9371 2001-11-13 Akim Demaille <akim@epita.fr>
9373 Now that tests are running in their own private dir, there is no
9374 need to list the files to remove at the end of tests groups.
9376 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
9377 (AT_data_files, at_data_files): Remove.
9378 (AT_CLEANUP, AT_DATA): Simplify.
9379 (AT_INIT): Adjust.
9380 Remove the group dir if !debug && !failed.
9381 * tests/atspecific.m4: Adjust.
9383 2001-11-13 Akim Demaille <akim@epita.fr>
9385 Start a new layout for Autotest: `testsuite' creates
9386 `testsuite.dir' in which the at-check-line etc. files are to be
9387 found, and `testsuite.dir/003' where the test group 3 is run.
9389 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
9390 at_check_line_file, at_format, at_test_normalized, at_group_dir
9391 are new variables.
9392 Create the directories.
9393 Use absolute paths for at- files.
9394 (AT_CHECK): Adjust.
9396 2001-11-11 Michael Matz <matz@kde.org>
9398 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
9399 (m4_car2): New.
9400 (m4_car): Properly quote arguments.
9402 2001-11-13 Akim Demaille <akim@epita.fr>
9404 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9405 with stricter rules on LIBOBJS.
9407 2001-11-12 Paul Eggert <eggert@twinsun.com>
9409 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9410 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9411 __PROTOTYPES too.
9413 2001-11-12 Akim Demaille <akim@epita.fr>
9415 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9417 2001-11-12 Akim Demaille <akim@epita.fr>
9419 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9420 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
9421 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9422 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9423 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9424 specify to what the macro should be defined (typically to 1).
9426 2001-11-12 Akim Demaille <akim@epita.fr>
9428 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9429 From Jim Meyering.
9431 2001-11-12 Akim Demaille <akim@epita.fr>
9433 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9434 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
9435 definition used by Automake where LEX is +/- "${missing} lex" and
9436 `missing' itself contains variables.
9438 2001-11-12 Akim Demaille <akim@epita.fr>
9440 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
9441 Now that M4sh pushes BODY, the comments were output at the end of
9442 the test suites.
9444 2001-11-08 Akim Demaille <akim@epita.fr>
9446 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
9447 that we can trace macros from aclocal.m4.
9448 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
9449 obsoleted, and redirect to the former anyway.
9450 Reported by Ralf Corsepius.
9452 2001-11-08 Akim Demaille <akim@epita.fr>
9454 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
9455 processed only if present.
9456 * tests/torture.at (Configuring subdirectories): Use autoreconf
9457 instead of successive calls to autoconf.
9458 Add a nonexistent subdirectory to exercise the patch above.
9459 Reported by Ralf Corsepius.
9461 2001-11-08 Kevin Ryde <user42@zip.com.au>
9463 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
9464 doesn't accept .S files.
9466 2001-11-07 Akim Demaille <akim@epita.fr>
9468 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
9469 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
9470 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
9471 * bin/autom4te.in (warn_forbidden): New.
9472 (handle_output): Use it.
9473 Read m4_pattern_forbid with messages.
9475 2001-11-05 Akim Demaille <akim@epita.fr>
9477 * bin/autom4te.in (--normalize): Remove.
9478 * lib/autom4te.in: Adjust.
9480 2001-11-05 Akim Demaille <akim@epita.fr>
9482 * tests/Makefile.am (testsuite): Rename this target as...
9483 ($(TESTSUITE)): this.
9484 From Nicolas Joly.
9486 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
9488 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
9489 the --prefix option, also remove it's argument.
9491 2001-11-05 Akim Demaille <akim@epita.fr>
9493 * doc/autoconf.texi (testsuite Invocation): Update.
9494 (Writing testsuite.at): Update.
9496 2001-11-03 Akim Demaille <akim@epita.fr>
9498 * doc/autoconf.texi: s/@code/@command/ where appropriate.
9500 2001-11-03 Akim Demaille <akim@epita.fr>
9502 * lib/Autom4te/General.pm: (&catfile, &canonfile)
9503 (&file_name_is_absolute): New, wrappers around routines from
9504 File::Spec.
9505 Use and export them.
9506 (&find_configure_ac): Optionally take a directory where to look at.
9507 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
9508 the arguments.
9509 Default @ARGV to `.', not find_configure_ac.
9510 (&autoreconf): Argument is a directory.
9511 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
9512 * doc/autoconf.texi (autoreconf Invocation): Update.
9514 2001-11-03 Akim Demaille <akim@epita.fr>
9516 * lib/Autom4te/General.pm (@export_vars, @export_subs)
9517 (@export_forward_subs): New.
9518 Add basename, dirname, and fileparse.
9519 (@EXPORT): Adjust.
9520 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
9521 Don't look for aclocal flags if we already know aclocal is not
9522 used.
9523 Move aclocal.m4t only if it exists.
9524 Reported by Ezra Peisach.
9526 2001-11-03 Akim Demaille <akim@epita.fr>
9528 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
9529 passed on command line, defaulting to ./configure.ac if present.
9530 (&maybe_autoreconf, File::Find): Remove, unused.
9531 (&autoreconf): If autoconf is not used, don't try to trace.
9533 2001-11-02 Akim Demaille <akim@epita.fr>
9535 * configure.ac: Bump to 2.52g.
9537 2001-11-02 Akim Demaille <akim@epita.fr>
9539 Version 2.52f.
9541 2001-11-02 Akim Demaille <akim@epita.fr>
9543 * config/config.guess, config/config.sub, doc/standards.texi:
9544 * config/lispdir.m4: Update from masters.
9545 * configure.ac: Bump to 2.52f.
9547 2001-11-02 Akim Demaille <akim@epita.fr>
9549 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
9550 Don't run aclocal when aclocal.m4 is not from aclocal.
9551 From Ezra Peisach.
9552 Don't run libtoolize and gettextize if --install is not given.
9554 2001-11-01 Paul Eggert <eggert@twinsun.com>
9556 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
9557 be invoked before _AS_LINENO_PREPARE.
9558 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9559 than character ranges.
9561 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9562 invoking AS_BASENAME. Set the locale variables to 'C' if
9563 possible, as POSIX requires this to get the traditional
9564 behavior.
9565 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9567 2001-10-31 Paul Eggert <eggert@twinsun.com>
9569 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9570 with {}, as that triggers a bug in Bash 2.05.
9572 (_AS_LINENO_PREPARE): Use Sed rather than
9573 Awk. Fix the sed prepass to work even if there are multiple
9574 instances of $LINENO on the same line. Do not substitute for
9575 other variables like $LINENOT. Do not check file dates; such a
9576 check is unreliable on sufficiently fast machines, and removing
9577 the check makes the code simpler and more reliable. Check for
9578 output and chmod failures.
9580 * doc/autoconf.texi (Special Shell Variables): Document
9581 the above.
9583 2001-10-31 Akim Demaille <akim@epita.fr>
9585 * tests/Makefile.am (atconfig): Remove this target, Automake
9586 handles it now.
9588 2001-10-31 Akim Demaille <akim@epita.fr>
9590 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
9591 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
9592 provided, while it is optional.
9593 * configure.ac: Adjust.
9595 2001-10-26 Paul Eggert <eggert@twinsun.com>
9597 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
9598 lib/Autom4te/Struct.pm:
9599 Require Perl 5.005_03 instead of just 5.005, as some tests fail
9600 with 5.005_02.
9602 * doc/autoconf.texi (Special Shell Variables): Document some
9603 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
9605 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
9606 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
9607 eval $LINENO is not portable in practice.
9609 2001-10-24 Akim Demaille <akim@epita.fr>
9611 * lib/Autom4te/General.pm (backname): New.
9613 2001-10-24 Akim Demaille <akim@epita.fr>
9615 * m4/: Remove, merged into...
9616 * config/: here.
9618 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
9620 * doc/autoconf.texi (Shellology): Mention the problems with bash
9621 2.05's use of ANSI quoting in its `set' builtin.
9623 2001-10-22 Paul Eggert <eggert@twinsun.com>
9625 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
9626 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
9627 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
9628 POSIX decided to standardize on the int flavor of strerror_r.
9629 Always do char* test, as there's no reason not to.
9630 Assign to a char* var, to catch strerror_r that returns int*.
9632 * doc/autoconf.texi (Particular Functions):
9633 Document the above changes. Also, document the fact that
9634 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
9636 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
9638 2001-10-20 Akim Demaille <akim@epita.fr>
9640 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
9641 the executable was missing from the log.
9643 2001-10-20 Akim Demaille <akim@epita.fr>
9645 * lib/Autom4te/General.pm (&update_file): If destination is
9646 unchanged, remove the source.
9647 (&up_to_date_p): Don't be verbose, be debug.
9648 * bin/autoreconf.in: No longer support --m4dir.
9649 (&autoreconf): Display the full path of the configure.ac we are
9650 studying.
9651 Trace it only once.
9652 Be sure to honor --force with gettextize.
9653 Always run aclocal.
9654 * doc/autoconf.texi: Adjust.
9656 2001-10-20 Akim Demaille <akim@epita.fr>
9658 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9659 Remove, dead.
9660 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9661 `intl' is already present, as it refuses unless --force.
9662 (&parse_args): Use -I, --include instead of the old Autoconf
9663 options.
9664 ($localdir, $autoconf_dir): Remove.
9665 (@include): New.
9666 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9668 2001-10-19 Jens Petersen <petersen@redhat.com>
9670 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

9673 2001-10-19 Akim Demaille <akim@epita.fr>
9675 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
9676 file in @configure_input@.
9677 Don't mention `automatically' in addition to `generated'.

9680 2001-10-19 Akim Demaille <akim@epita.fr>
9682 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
9683 comment, explain how to install automatic mode selection.
9684 From Russ Allbery.
9686 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
9688 * bin/autoreconf.in (autoreconf): Display the path to the
9689 configure.ac being studied.
9691 2001-10-18 Paul Eggert <eggert@twinsun.com>
9693 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
9694 long, to work around a bug in the HP C compiler version HP92453-01
9695 B.11.11.23709.GP.
9697 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
9698 (AS_BASENAME_EXPR): New macro.
9699 (AS_BASENAME_SED): Do not assume GNU sed semantics.
9700 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
9701 and fall back on 'sed' only if the other two fail. This makes
9702 AS_BASENAME act more like AS_DIRNAME.
9703 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
9704 contains white space.
9705 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
9706 Use AS_DIRNAME, since I think it's now DOS-friendly.
9707 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9708 Allow "dirname //FOO" to return either / or //, as POSIX allows
9709 either behavior.
9711 2001-10-10 Akim Demaille <akim@epita.fr>
9713 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
9714 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
9715 From Eric Sharkey.
9717 2001-10-10 Akim Demaille <akim@epita.fr>
9719 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

9721 (_AS_ECHO_N): AS_REQUIREs it.
9723 2001-10-10 Akim Demaille <akim@epita.fr>
9725 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)

9743 (Autoconf): Use it.
9745 2001-10-08 Akim Demaille <akim@epita.fr>

9762 2001-10-08 Akim Demaille <akim@epita.fr>
9764 * bin/autoreconf.in: Rewrite in Perl.
9765 * configure.ac: Adjust.

9812 M4sugar peer, i.e., drop the `AC_PROVIDE_$1' broken marker.
9814 2001-10-08 Akim Demaille <akim@epita.fr>
9816 Use `add-log-current-defun-function' for ChangeLog creation.

9845 CONFIG_SHELL defaults to a shell that supports LINENO if available.
9847 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
9848 shell does not support LINENO, and if CONFIG_SHELL is unset or
9849 empty, and if we can find a shell that does support LINENO,
9850 then set CONFIG_SHELL to that shell and then re-execute
9851 ourselves with CONFIG_SHELL.
9853 2001-10-05 Paul Eggert <eggert@twinsun.com>
9855 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
9856 doesn't exist. Remove *.tmp, as a .tmp file is created during the
9857 build of $(TESTSUITE).
9859 2001-10-05 Akim Demaille <akim@epita.fr>
9861 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

9898 compatibility with POSIX shells.

9926 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
9927 Don't use nested parenthesization. This patch was originally
9928 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
9929 but somehow it didn't get incorporated then.

9937 Check for `expr' arithmetic overflow, and for compilation failure,
9938 and invoke a new argument $4 if either is discovered.
9939 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
9940 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

9970 * tests/c.at (Extensions, C keywords)
9971 (Broken/missing compilers, AC_PROG_CPP with warnings)
9972 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
9973 (AC_PROG_CPP requires AC_PROG_CC): here and...
9974 * tests/fortran.at (GNU Fortran 77): there.
9975 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9976 AC_TRY_RUN is about compilation, not shell commands.
9977 (Test Programs): AC_TRY_RUN works as used to be advertised.
9979 2001-09-27 Akim Demaille <akim@epita.fr>
9981 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
9982 Raja R Harinath:
9983 Be sure to detect when $LINENO always returns the same value.
9984 Look for the original script, basename($0) is certainly not
9985 enough.
9986 Pass the CLI arguments to `$as_me.lineno'.
9988 2001-09-25 Akim Demaille <akim@epita.fr>
9990 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

10007 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
10008 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
10009 builddir, buildpath, top_builddir, and top_buildpath.
10010 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
10011 the current directory.
10012 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir

10024 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
10025 Remove.

10028 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
10029 * configure.ac: Build the position independent wrappers.

10036 * doc/autoconf.texi (Common Shell Constructs): Rename as...
10037 (Programming in M4sh): this.

10081 * tests/Makefile.am (package.m4): Remove.
10083 2001-09-22 Akim Demaille <akim@epita.fr>
10085 Rely on `$LINENO' when possible instead of `__oline__'.
10087 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
10088 `$LINENO' support replacement when not supported.
10089 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
10090 them explicitly to be sure they are not output before this section
10091 (via m4_require). Cosmetic only.
10092 * lib/autoconf/c.m4, lib/autoconf/general.m4,
10093 * lib/autoconf/programs.m4: Replace all the occurrences of

10099 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
10100 character (u: -> ue) in a code comment.
10101 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
10102 it works.
10104 2001-09-21 Akim Demaille <akim@epita.fr>
10106 * Makefile.maint (AUTOM4TE): Neutralize autom4te.

10121 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

10134 arguments. Fixed a typo.
10136 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10138 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

10141 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10143 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

10150 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10152 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10153 already have $file). Set output files to binary mode (helps avoid
10154 CR issues on DOSish systems).
10156 2001-09-19 Akim Demaille <akim@epita.fr>
10158 * lib/autotest/general.m4: Englishoes.
10159 From Tim Van Holder and Alexey Mahotkin.
10161 2001-09-18 Paul Eggert <eggert@twinsun.com>
10163 * doc/autoconf.texi (Common Shell Constructs): New node,
10164 documenting AS_DIRNAME.
10165 (Limitations of Usual Tools): Refer to it when discussing dirname.
10166 Also, update discussion of POSIX standard to reflect latest draft.
10168 * lib/autoconf/c.m4:
10169 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
10171 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10172 Do not pass a first argument with leading '-'
10173 to expr, by parenthesizing initial integers that might be negative.
10175 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10176 now merely checks whether it is an error to pass an argument
10177 to getpgrp.
10179 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10180 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
10181 whether it is a (compile-time) error to pass an argument to
10182 getpgrp. This simpler test supports the revised documentation,
10183 and is all that AC_FUNC_GETPGRP's users really need.
10185 2001-09-18 Akim Demaille <akim@epita.fr>
10187 * doc/autoconf.texi (Limitations of Make) <$<>: New.

10197 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
10198 correctly.
10199 Add test for AS_BASENAME.
10200 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10201 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10202 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10203 * tests/base.at: Fixed the expected responses. The old ones were
10204 one line out...
10205 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10206 the documentation claims it should (and how it behaved in 2.13).
10208 2001-09-18 Akim Demaille <akim@epita.fr>
10210 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
10211 the AC_CONFIG_COMMANDS invocation.
10212 This also solves the name clash problems.
10213 Don't set the package's ID.
10214 * lib/m4sugar/Makefile.am (version.m4): Revamp.
10215 No longer to be shipped.
10216 (version.in): Remove.

10218 * lib/autoconf/status.m4: Adjust.
10219 Use `m4_PACKAGE_STRING'.
10220 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
10221 the only optional argument is the name of the test suite.
10222 Expect `package.m4' to define the package signature.
10223 * lib/autom4te.in (Autotest): Add `package.m4?'.
10224 * tests/Makefile.am (package.m4): New.
10225 * tests/suite.at: ifnames is a victim.
10227 2001-09-18 Akim Demaille <akim@epita.fr>
10229 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
10230 AC_LIBSOURCE, AC_CONFIG_FILES.
10231 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
10232 program version string doesn't match the package's.
10233 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
10234 after `(cached)'.
10236 2001-09-17 Paul Eggert <eggert@twinsun.com>
10238 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10239 Allow expression to return any value that can fit into unsigned long
10240 (not int, as before). Check for output errors.
10242 2001-09-17 Bruno Haible <haible@ilog.fr>
10244 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10245 Always include <stdio.h> and <stdlib.h>. Evaluate
10246 the expression in an extra function before these includes. Call
10247 fprintf "%d" only after ensuring the argument is of type 'int'.

10252 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10253 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10254 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10255 when they don't exist.
10257 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
10258 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
10259 need it.
10261 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
10262 version with the version used by fileutils 4.1, except use
10263 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
10264 we don't need it.
10266 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
10268 2001-09-13 Akim Demaille <akim@epita.fr>
10270 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
10271 _first_.

10276 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

10308 * lib/autotest/general.m4 (AT_INIT): Create and remove
10309 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

10399 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,

10420 2001-09-05 Akim Demaille <akim@epita.fr>
10422 Be ready to handle filenames as stupid as `dnl.at', for if even
10423 the maintainer is dumb enough to do that...
10425 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
10426 excellence in M4 quotation: consider `__file__' is active.
10428 And BTW, when invoking m4, pass the --include in the right order:
10429 the wrong one.
10431 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
10432 4m.

10456 CVS GNU M4 doesn't like `undefine(undefined)'.
10458 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
10459 New, extracted from main.
10460 Use IO::File wherever possible.
10461 (input.m4): Be constant, use -I instead of hard coding $tmp.
10462 Therefore be a quoted heredoc.
10463 Don't invoke `_au_disable', since ac was not loaded, but just
10464 `unm4.m4'.
10466 2001-08-31 Akim Demaille <akim@epita.fr>
10468 Version 2.52d.

10491 2001-08-31 Akim Demaille <akim@epita.fr>
10493 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
10494 (testsuite Scripts): There is no such thing as `atconfig.in'.
10495 And actually one diagram is missing: test suite runtime.
10497 2001-08-31 Akim Demaille <akim@epita.fr>
10499 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
10500 inverse order.
10502 2001-08-31 Akim Demaille <akim@epita.fr>
10504 * bin/autoupdate.in (@include): `installcheck' revealed the path
10505 to m4sugar was lacking!
10507 2001-08-31 Akim Demaille <akim@epita.fr>
10509 * man/Makefile.am (.x.1): We really have to pass
10510 autom4te_perllibdir.
10512 2001-08-31 Akim Demaille <akim@epita.fr>
10514 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
10515 debug scripts, in particular passing explicitly listed tests to
10516 run is stupid.
10518 2001-08-31 Akim Demaille <akim@epita.fr>
10520 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
10521 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
10522 Use directly autom4te, not autoconf.
10523 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
10525 2001-08-31 Akim Demaille <akim@epita.fr>
10527 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

10536 * bin/autom4te.in (&parse_args): Die on unknown languages.
10537 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
10538 need for autoconf.
10539 Promote --include over --macrodir and other obsolete options.
10541 2001-08-31 Akim Demaille <akim@epita.fr>
10543 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

10545 * bin/autom4te.in ($autoconf): Pass --force.
10546 `print $out' doesn't print `$_' but `$out'.
10547 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
10548 (autoheader): Pass --force since the test suite goes too fast for
10549 the time stamps.
10550 Adjust to the new autoheader messages.
10552 2001-08-31 Akim Demaille <akim@epita.fr>
10554 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
10555 Check the completeness of the #template.

10564 Drop AC_MACRODIR dead for real.
10565 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
10566 `autoheader: `config.hin' is created'.
10567 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
10569 2001-08-31 Akim Demaille <akim@epita.fr>
10571 * bin/autoheader.in: Rewrite in Perl.
10572 * tests/autoheader: Adjust.
10574 2001-08-31 Akim Demaille <akim@epita.fr>
10576 * bin/autoconf.in (--include, -I): New option.
10577 Map --localdir, --autoconf-dir onto it.
10578 Forward autom4te's options instead of interpreting them.
10579 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
10580 There is no such envvar since the inception of autom4te.cfg.
10581 * bin/autom4te.in (&parse_args): Uniquify `@include'.
10582 * bin/autoupdate.in: Adjust, and perform more control.
10583 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.

10586 2001-08-31 Akim Demaille <akim@epita.fr>
10588 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
10589 * bin/autom4te.in (&find_file): Support `FILE?' standing for
10590 optionally `FILE'.
10591 Use -e, not -f, since /dev/null for instance is OK.
10592 (&parse_args): Adjust.
10593 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
10595 2001-08-31 Akim Demaille <akim@epita.fr>
10597 * configure.ac: Also find tested executables in bin.
10598 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
10599 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
10600 installed peer executables, only PATH is allowed to resolve it.
10601 Pass `autoconf_dir' via options, not via invisible envvars.
10602 * lib/Autom4te/General.pm (&find_peer): Remove.
10603 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
10604 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
10605 * man/Makefile.am: Let help2man rely on PATH instead of trying to
10606 find the executables for it.
10607 * tests/Makefile.am: Major cleanup. Too lazy to document...
10608 * tests/atlocal.in: Remove all the obscure envvar manipulations.
10609 We only need PERL.
10610 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
10611 indeed related to running the test suite, while passing
10612 --autoconf-dir and others is related to running non installed
10613 Autoconf executables. So don't do that, leave it to...
10614 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
10615 * tests/autoscan: New.
10616 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
10617 refer to library files: rely on --language.
10619 2001-08-29 Akim Demaille <akim@epita.fr>
10621 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

10624 2001-08-29 Akim Demaille <akim@epita.fr>
10626 * doc/autoconf.texi: Strip the @nodes.
10627 Suggested by Paul Eggert.

10630 2001-08-29 Akim Demaille <akim@epita.fr>
10632 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
10633 Suggested by Paul Eggert.
10635 2001-08-29 Akim Demaille <akim@epita.fr>
10637 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
10638 download in a tmp dir.
10640 2001-08-29 Akim Demaille <akim@epita.fr>
10642 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

10654 * bin/autoconf.in: Simplify and adjust.
10655 * tests/Makefile.am (AUTOMAKE): Use --set.
10656 * tests/atlocal.in: Adjust.
10657 * BUGS: distcheck and check are weak.
10659 2001-08-29 Akim Demaille <akim@epita.fr>
10661 * lib/autotest/general.m4: Use
10662 foo=`(command) 2>/dev/null`
10663 not
10664 foo=`command` 2>/dev/null
10665 (at-devnull): Rename as...
10666 (AT-devnull): this.
10667 (--clean): Remove AT-* files too.
10668 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
10669 Reported by Nicolas Joly.

10688 2001-08-27 Akim Demaille <akim@epita.fr>
10690 * Makefile.maint: Formatting changes.
10691 (do-po-update, po-update, cvs-update, update): New targets.

10694 2001-08-27 Akim Demaille <akim@epita.fr>
10696 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

10701 2001-08-27 Akim Demaille <akim@epita.fr>
10703 * lib/autotest/general.m4 (AT_INIT): Log the command line.
10704 Support `VAR=VAL' as arguments.

11175 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
11177 * tests/semantics.at (AC_C_BIGENDIAN): New test.
11179 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11181 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
11182 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
11183 * doc/autoconf.texi (C Compiler Characteristics): Update
11184 documentation for AC_C_BIGENDIAN.
11186 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11188 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11189 magic values from an object file when cross-compiling.
11190 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11192 2001-08-10 Akim Demaille <akim@epita.fr>
11194 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11195 effects.
11196 Suggested by Russ Allbery.
11198 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11200 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11201 current $prefix to the sub-configures.
11203 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11205 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
11206 extension (needed on BeOS). Reported by Guido van Rossum.
11208 2001-08-09 Akim Demaille <akim@epita.fr>
11210 * bin/autom4te.in ($icache): Load it only if older than autom4te.
11212 2001-08-07 Akim Demaille <akim@epita.fr>
11214 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11215 removed.
11216 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11217 No need to remove the files before and after the each test, before
11218 each test and at the end of the suite is enough.
11219 Display only the children `times', not the shell's.
11220 If the test failed or was skipped, at-times is not available.
11222 2001-08-07 Akim Demaille <akim@epita.fr>
11224 Always produce testsuite.log, including when there are no
11225 failures. This helps getting information on skipped tests, and
11226 duration of the tests. Err, implement the latter btw.
11228 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
11229 Dump information on the first run of each test.
11230 (AT_CLEANUP): Create `at-times' containing the duration of the
11231 test group.
11233 2001-08-07 Akim Demaille <akim@epita.fr>
11235 The use of `dumpstat' revealed that `len' was used although it
11236 should not. m4_text_wrap was using it, but in the Autoconf world
11237 where it is legal. Hence (i) test M4sh in its own world, not
11238 Autoconf's, and (ii), ahem, fix the bug :)
11240 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11241 does not like `' instead of [].
11242 (AT_INIT): Forbid `^_?AT_'.
11243 And don't output such tokens.
11244 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11245 `script.as', and `autom4te.cache'.
11246 Remove `empty' and `macro' which are no longer used.
11247 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11248 * tests/m4sugar.at: Use it.
11249 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11251 2001-08-07 Akim Demaille <akim@epita.fr>
11253 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
11255 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
11257 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
11259 2001-08-04 Akim Demaille <akim@epita.fr>
11261 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
11262 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
11263 AC_TRY_LINK.
11264 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
11265 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
11266 (AC_F77_MAIN): Likewise.
11268 2001-08-04 Akim Demaille <akim@epita.fr>
11270 Don't rely on M4sugar outputting the patterns in files, since we
11271 might process the output _without_ running m4, hence without these
11272 files.
11274 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
11275 * bin/autom4te.in (@Request::includes): Remove, unused.
11276 (@Request::source): Rename as...
11277 (@Request::input): this.
11278 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
11279 (&handle_output): Fetch the patterns from the traces.
11280 `$forbidden' and `$allowed' are constant: use m//o.
11281 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
11282 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
11284 2001-08-04 Akim Demaille <akim@epita.fr>
11286 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
11287 autoconf', i.e., in addition to caching traces, cache the output.
11289 * bin/autom4te.in (Request::cache): Rename as...
11290 (Request::id): this.
11291 ($cache, $icache, $tcache, $ocache): New.
11292 (&handle_m4): Save M4 output in the cache instead of $tmp.
11293 (&handle_output): Adjust.
11294 (&up_to_date_p): Check that the output cache is up to date too.
11295 (top level): Run `&handle_m4' iff force or the cache is invalid.
11296 Run `&handle_output' if the output cache is more recent.
11298 2001-08-04 Akim Demaille <akim@epita.fr>
11300 * bin/autom4te.in ($force): New.
11301 (&parse_args, &print_usage): -f, --force is a new option.
11302 (&handle_output): CPP directives might have spaces after `#'.
11303 (&parse_args): The first file only can be frozen.
11305 2001-08-04 Akim Demaille <akim@epita.fr>
11307 Don't let autom4te compute the `include' traces several times:
11308 first check that the trace cache file is up to date, and then
11309 compare its timestamp with that of the output.
11311 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
11312 the preamble. Don't require 5.005 as Autom4te::General does it,
11313 and better yet (use `use', not `require'!).
11314 * lib/Autom4te/Struct.pm: Rename the last occurrences of
11315 Class::Struct as Autom4te::Struct.
11316 * lib/Autom4te/General.pm (File::stat): Use it.
11317 (&mtime): New, export it.
11318 * bin/autom4te.in: Use it.
11319 Declare `$req' is invalid if it is outdated.
11320 Don't declare it valid before saving it if something went wrong.
11322 2001-08-04 Akim Demaille <akim@epita.fr>
11324 Autom4te shall not encode Autoconf data, and preselecting traces
11325 must be proposed to the users.
11327 * bin/autom4te.in (@required_trace): Remove.
11328 (@preselect): New.
11329 (&parse_args, &print_usage): -p, --preselect is a new option.
11330 (&up_to_date_p): Adjust.
11331 * bin/autoconf.in: Preselect some Autoconf macros.
11333 2001-08-04 Akim Demaille <akim@epita.fr>
11335 * tests/tools.at (autoconf --trace: user macros): Check traces on
11336 macros invoked without arguments, and macros invoked with multiple
11337 lines arguments.
11339 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
11341 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
11342 arguments.
11344 2001-08-03 Akim Demaille <akim@epita.fr>
11346 * bin/autoconf.in ($@): Work around the usual sh bug.
11347 From Nicolas Joly.
11349 2001-08-03 Akim Demaille <akim@epita.fr>
11351 Clean up the handling of the M4 builtins tracing exception.
11353 * bin/autom4te.in (Request::request): Don't complete M4 builtins
11354 trace requests.
11355 (@m4_builtins): Rename as...
11356 (@m4_builtin): this.
11357 (%m4_builtin_alternate_name): New.
11358 (&parse_args): Complete the trace requests with alternate names.
11359 (&handle_traces): Hence no longer do it here.
11360 (&trace_requests): Remove, unused.
11362 2001-08-03 Akim Demaille <akim@epita.fr>
11364 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
11365 m4_if, and m4_wrap.
11367 2001-08-03 Akim Demaille <akim@epita.fr>
11369 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
11370 (m4_divert_pop): Dump the whole diversion stack when a diversion
11371 mismatch happens.
11372 * bin/autom4te.in (&handle_output): Remember of the first
11373 occurrence of a possibly undefined macro, not the last.
11374 Complain about the possibly undefined macros in the same order as
11375 the appear in the output.
11376 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
11377 * tests/tools.at (autoconf: forbidden tokens, basic)
11378 (autoconf: forbidden tokens, exceptions): No longer sort
11379 autoconf's stderr, as it is now deterministic.
11380 Check that `dnl' is caught.
11382 2001-08-01 Akim Demaille <akim@epita.fr>
11384 * configure.ac: Bump to 2.52c.

11396 2001-08-01 Akim Demaille <akim@epita.fr>
11398 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
11399 `die'.
11400 (&END): New.
11401 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
11402 `END', as `Autom4te::General::END' will be triggered.
11403 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
11404 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

11839 cross-language link tests can be performed successfully.
11840 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
11841 after $LIBS, for consistency; this should be the general rule since
