77 and Joel E. Denny <jdenny@ces.clemson.edu>
78 and Paul Eggert <eggert@cs.ucla.edu>
80 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
81 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
82 ./micro-suite.
84 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
86 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
87 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
88 Imported from a similar patch to gnulib by Bruno Haible.

109 and Stepan Kasal <kasal@ucw.cz>
111 Handle special characters in test case titles correctly.
112 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all

114 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
115 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST

119 Single-quote in a test title,
120 Double-quote in a test title): Don't expect failure anymore.
121 (Backslash in a test title): Put a non-whitespace character after the
122 backslash so that Bourne shells might actually see it as an escape
123 sequence.
124 (Brackets in a test title,
125 Pound in a test title,
126 Comma in a test title,
127 Quoted Macro in a test title,

132 Macro with backslash in a test title): New tests expected to fail.
133 * tests/torture.at (#define header templates): M4-quote this title in
134 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
135 The visible effect was a stray [] in the testsuite output.
137 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
139 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
140 `trap ... 0' inside a function, for AIX sh.
142 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
144 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
145 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
146 5363) simply issues a warning when dividing by zero at compile
147 time. Problem reported by Elias Pipping.
149 2006-10-26 Eric Blake <ebb9@byu.net>
151 * THANKS: Update.
152 * doc/autoconf.texi (Evaluation Macros): Improve the example to

178 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
180 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
181 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
182 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
183 reported by Nelson H. F. Beebe for Coreutils 6.4.
185 * tests/tools.at (autoconf --trace: user macros): Remove test
186 for tracing multiline macros, since m4 1.4.7a uses a different
187 way to number lines. Problem reported by Ralf Wildenhues.
189 2006-10-24 Stepan Kasal <kasal@ucw.cz>
191 * bin/autom4te.in (handle_m4): Do not redirect stdin to
192 /dev/null since the heuristics for interactive behaviour was
193 fixed in CVS m4.
195 * bin/autom4te.in: With --force, always refresh the output
196 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

211 * build-aux/texinfo.tex: automake 1.10
213 * NEWS: Remove AC_CACHE_CHECK_INT.
214 * doc/autoconf.texi (Caching Results): Likewise.
215 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
216 AC_CACHE_CHECK_INT, since it's no longer public.
217 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
218 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
220 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
222 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.

227 (m4_maketemp): Avoid warnings with M4 1.9a.
228 * lib/emacs/autoconf-mode.el (autoconf-font-lock-keywords): Color
229 m4_mkstemp.
230 * doc/autoconf.texi (Redefined M4 Macros): Document m4_mkstemp.
231 * NEWS: Likewise.
233 2006-10-16 Eric Blake <ebb9@byu.net>
235 * doc/autoconf.texi (Setting Output Variables): Fix typo.
237 * bin/autoconf.as (version): Reword to match GNU Coding
238 Standards.
239 * bin/autoheader.in (version): Likewise.
240 * bin/autom4te.in (version): Likewise.

242 * bin/autoscan.in (version): Likewise.
243 * bin/autoupdate.in (version): Likewise.
244 * bin/ifnames.in (version): Likewise.
246 2006-10-14 Stepan Kasal <kasal@ucw.cz>
248 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
249 looking for special shell characters.
250 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
251 macro defined by AS_VAR_PUSHDEF before passing it as a
252 parameter.
253 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
254 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

263 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
265 (Imported from Automake.)
266 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
267 which incorrectly sets the mode of an existing destination
268 directory. In some cases the unpatched install-sh could do the
269 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
270 system. We hope this is rare in practice, but it's clearly worth
271 fixing. Problem reported by Alex Unleashed in
272 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
273 Also, don't bother to check for -m bugs unless we're using -m;
274 suggested by Stepan Kasal.
276 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
278 Import this change from Automake:
280 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
281 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
282 is enabled by default with gnu and gnits strictness.
283 Report from Bruno Haible.
285 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
286 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
287 gnu and gnits modes.
289 Import this change from Config:
291 2006-09-20 Ben Elliston <bje@gnu.org>
292 * build-aux/config.sub (score, score-*): New.
294 Import this change from Gnulib:
296 2006-09-16 Karl Berry <karl@gnu.org>
297 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
298 to avoid sectioning errors.
300 Import these changes from Texinfo:
302 2006-10-04 Karl Berry <karl@gnu.org>
303 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

305 (\codequoteleft): new def, to look for @set codequotebacktick.
306 (\lquoteexpand, \quoteexpand): new defs.
307 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
308 (\code): must use new \...Char values, since now ` is active.
310 2006-08-26 Karl Berry <karl@gnu.org>
311 * build-aux/texinfo.tex (\textdegree): New command.
313 2006-08-12 Karl Berry <karl@gnu.org>
314 * build-aux/texinfo.tex (error \box0): smaller font.
316 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
318 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
320 2006-10-13 Stepan Kasal <kasal@ucw.cz>
322 * doc/autoconf.texi (Autoheader Macros): Warn that the text
323 added to the template can get mangled.
325 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
327 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
328 include the default headers, and redefine obstack_chunk_alloc
329 and obstack_chunk_free. Fixes false failure with glibc.
331 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
333 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
334 for backward compatibility with Libtool 1.5.22. Problem reported
335 by Ralf Wildenhues.
337 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
339 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
340 AC_PROG_CC.
341 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
343 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
345 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
346 the NonStop platform.
347 * doc/autoconf.texi (Posix Variants): Likewise.
348 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
350 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
351 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
352 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
353 Use a better substitute, by inspecting the output of "ls"
354 rather than just using ":".
355 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
356 rather than AS_EXECUTABLE_P, since we needn't worry about
357 non-regular files here.
359 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
360 due to configuration hassles with this. See Tonya Underwood's report
361 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
362 * doc/autoconf.texi (Special Shell Variables): Likewise.
364 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
365 Stepan Kasal <kasal@ucw.cz>
367 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
368 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
370 2006-10-11 Stepan Kasal <kasal@ucw.cz>
372 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
373 initialization which is not inherited through the environment
374 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
375 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
377 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
379 * doc/autoconf.texi (Limitations of Usual Tools): Describe
380 problems with mkdir -p -m.
382 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
384 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
385 comment about ac_cpp_err; it was incorrect, and anyway
386 ac_cpp_err is being removed below.
387 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
388 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
389 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
390 nobody uses it.
391 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
392 with werror_flag and conftest.err and so forth. This is more
393 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
394 and anyway the user shouldn't normally want to see this gorp logged.
395 Problem reported by Ralf Wildenhues.
396 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
397 empty, not 'no', since the rest of the code uses 'test -z'.
399 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
401 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
402 Use a single call to AC_DO_TOKENS rather than multiple, for
403 efficiency.
404 (_AC_LINK_IFELSE): Test that resulting file is executable.
405 Problem reported by mwoehlke in
406 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
408 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
409 than creating a file to use with test -x; this is much faster.
411 2006-10-02 Bruno Haible <bruno@clisp.org>
413 * lib/autom4te.in (Automake-preselections): Add
414 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
416 2006-09-27 Stepan Kasal <kasal@ucw.cz>
418 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
419 standard error, `experr' should be used, not `expout'.
421 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
423 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
424 fseeko testing program twice; just use the earlier result.
425 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
426 Set cache var to 'unknown' (not 'no') if leaving the macro unset
427 still doesn't let the program compile.
428 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
429 failed.
431 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
432 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
433 include it, without including anything else.
434 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
435 expressions.
436 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
438 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
440 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
441 `error.h', and include it, for a `error_at_line' prototype.
442 Use a nonempty format string in the link test.
443 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
444 for a declaration of wait3.
446 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
448 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
449 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
450 can apply to constants too, and that it checks for macro defns.
451 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
452 and simply cast the identifier to void. This handles structure
453 values. Problem reported by Ralf Wildenhues.
454 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
456 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
458 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
459 structure, and function symbols.

475 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): Avoid `gcc -Wall'
476 warnings (uninitialized value).
477 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
478 present.
479 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add
480 parentheses.

510 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
511 --error-output, to avoid warnings with M4 2.0.
513 2006-09-19 Stepan Kasal <kasal@ucw.cz>
515 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

542 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
543 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
544 for the existence of the directory at configure-time. That's
545 too late, anyway. Problem reported by Stefan Seefeld.
547 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
548 7.1.4 /usr/bin/posix/sh described by Tim Rice in
549 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.

564 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
565 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
566 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
567 assume C89.

587 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
589 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
590 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
591 accept files with extension `.f'. For consistency, also prefer
592 xlf over f77.
593 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
594 from last patch.

611 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
613 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
614 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
615 except the first two arguments are reversed.
616 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.

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

798 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
799 -Wundef -Werror". Problem reported by David Fang in

822 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
823 problems with arg script text that doesn't end in newline, and

826 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
828 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

867 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
868 compiler complains about it, even if things works after the
869 complaint. Problem reported by Peter O'Gorman.

872 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
873 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
875 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
877 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

879 fixes things on NetBSD 3.99.
881 * NEWS: Recommend M4 1.4.5.
882 * README: Likewise.
883 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

897 * doc/autoconf.texi: Fix some typos.
899 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
901 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
902 more globally, since the 2006-06-30 patch didn't suffice. Problem
903 reported by Keith Marshall. Also, don't bother with builddir2,
904 since it shouldn't be needed any more.
906 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
908 * doc/autoconf.texi (Generic compiler characteristics):
909 Document AC_COMPUTE_INT. Fix wrong statements on Default

925 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
927 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
928 Require that long long int be at least 64 bits wide. C99 requires
929 this and enough programs depend on it so we should check for it.
930 Bruno Haible reports in
931 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
932 that long long int is 32 bits wide with some nonstandard compilers.
933 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
935 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
937 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
938 to a nonexistent file, so that we don't have to worry about
939 a local site configuration that doesn't use /usr/local.
940 Problem reported by Keith Marshall in
941 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
943 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
945 * doc/autoconf.texi: Be more consistent about using @acronym with
946 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
947 quite right (it talked about "OSF/Tru64", even though the
948 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
949 and it even mentioned "OSF 4"!) and at this point there's little
950 reason to talk about OSF any more, since it died in 1994.
951 (Specific Compiler Characteristics): Simplify example of
952 negative-size array.
953 (File Descriptors): Reorder to make the text flow better.
954 Remove joke about "appreciate the various levels"; I didn't get it.
955 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
956 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
957 (File Descriptors, Limitations of Usual Tools):
958 Tone down the advice against renaming or removing open files.
959 (Limitations of Usual Tools): Add a new section, on 'rm'.
961 2006-06-26 Stepan Kasal <kasal@ucw.cz>
963 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
964 -lXt in LIBS, idea from Karsten Hopp; this was due since
965 this change:
967 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
968 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
969 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
970 (which belong to Xt, not X itself). See Debian bug 327655.
972 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
974 * configure.ac (AC_INIT): Bump to 2.60a.
975 * NEWS: Update.
977 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
979 Version 2.60.
981 * configure.ac, NEWS: Update.
983 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
985 * config/texinfo.tex: Sync from upstream.
987 * bin/autom4te.in (handle_traces): Transform the `@S|@'
988 quadrigraph correctly in traces.
990 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
991 Fix typos.
993 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
994 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
995 not defined.
996 * doc/autoconf.texi (Changed Directory Variables): New node,
997 to document the whole `datarootdir' business a bit better.
998 * NEWS: Update.
999 * tests/torture.at (datarootdir workaround): Extend test.
1000 Prompted by report by Alexandre Julliard.
1002 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1004 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1005 when using default mode of IBM C 6 for AIX. Problem and two-line
1006 fix reported by Larry Jones.
1008 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1010 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1011 about literal '${datarootdir}' if a definition is found in the
1012 output file.
1014 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1016 * NEWS: Use "M4" rather than "m4" when appropriate.
1017 Problem reported by Eric Blake.
1018 * doc/autoconf.texi: Likewise.
1019 Use @acronym around BSD, GCC, and GNU when appropriate.
1020 (Why GNU M4): Renamed from "Why GNU m4".
1021 (Redefined M4 Macros): Mention that Posix
1022 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1023 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1024 to int.
1026 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1028 * bin/autom4te.in (handle_output): Do not forbid the empty
1029 pattern.
1030 * tests/tools.at (autoconf: the empty token): New test.
1032 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1034 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1035 calls, so that we do not care whether they are LIFO or FIFO;
1036 in the m4_wrap, do not check which diversion is the topmost
1037 one, just check that the stack is balanced at the end.
1038 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1039 base diversion forever--pop the previous diversion before
1040 opening the new one; consequently, remove the m4_wrap call.
1041 * lib/autotest/general.m4 (AT_INIT): Likewise.
1042 * tests/m4sugar.at: Do not use
1043 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1045 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1046 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1048 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1049 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1050 Rework example of m4wrap token-pasting trouble so that it doesn't
1051 care whether it's LIFO or FIFO.
1052 Fix some "contrary to"s that are awkward in English.
1054 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1056 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1057 to `yes' instead of `int$1_t' if the type is found, for more
1058 consistent configure output (where $1 is the number of bits).
1059 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1060 Suggested by Bruno Haible.
1062 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1063 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1064 with system headers. Report by Bruno Haible.
1066 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1068 * config/config.guess, config/config.sub: Sync from upstream.
1070 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1071 in order to avoid picking up an older installed frozen m4sh.m4f.
1072 Besides an outdated shell startup, this could have been created
1073 by an earlier M4 version with incompatible frozen file format.
1075 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1077 * README: Recommend m4 1.4.4 instead of 1.4.3..
1078 * doc/autoconf.texi: Likewise.
1079 (Special Chars in Names): Say that $(.FOO) is portable, as
1080 suggested by Stepan Kasal.
1081 (Installation Directory Variables, Build Directories):
1082 (Automatic Remaking, Subdirectories, Fortran Compiler):
1083 (Making testsuite Scripts, Defining Directories):
1084 Quote variable usages better.
1085 (Making testsuite Scripts): Add clean-local rule to makefile
1086 snippet, by Eric Blake.
1087 (Installation Directory Variables): Fix table item font.
1088 Reword slightly to clarify. Generalize advice about
1089 not using special characters to include all file-related
1090 vars, not just VPATH.
1091 (Special Chars in Variables): Warn about special characters in
1092 $(srcdir) too.
1093 (Assignments): Clarify default-value example as suggested by
1094 Ralf Wildenhues in
1095 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1096 (Special Shell Variables): Note leading ./ or ../, as suggested
1097 by Eric Blake.
1098 (Limitations of Builtins): Under cd, warn about CDPATH.
1099 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1100 Ralf Wildenhues.
1102 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1104 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1105 `@var', for texi2html.
1106 (Systemology): Some more word wrapping, for DVI output.
1107 (autom4te Invocation): The short option for `--melt' is `-M',
1108 not `-m'.
1110 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1112 * doc/autoconf.texi: More formatting and English tweaks,
1113 many suggested by Ralf Wildenhues.
1114 Reword to avoid "@code{...}'s" and the like, since it's ugly
1115 with Emacs info mode. discontents -> woes.
1116 Put a few "will"s back. time stamp -> timestamp.
1117 side-effect -> side effect.
1119 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1121 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1122 Warn about $@ not persisting. Problem reported by Julien Danjou in
1123 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1124 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1125 Mention other special chars, too.
1127 2006-06-14 Eric Blake <ebb9@byu.net>
1129 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1131 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1133 * doc/autoconf.texi: Some systematic minor improvements, as
1134 follows. Use "makefile" when talking about makefiles
1135 generally (which might be named "makefile" or "Makefile" or even
1136 "foo.mk"), "Makefile" when talking about a specific makefile
1137 called "Makefile". This unclutters the text from weird quotes
1138 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1139 values" rather than "@var{foo}s" and similar constructs containing
1140 "}s". Use "Make rules" rather than "Makefile rules". Minor
1141 English-language improvements. Change the prefix "sub-" to "sub"
1142 and "re-" to "re".
1143 Put blank lines around examples more consistently.
1144 Avoid "rather" and "very" as intensifiers.
1145 Avoid "will" as an auxiliary.
1146 (Limitations of Make): Split this node into....
1147 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1148 (Leading _ in Macro Names, Backslash-Newline-Newline):
1149 (Backslash-Newline Comments, Long Lines in Makefiles):
1150 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1151 (obj/ and Make, make -k Status, VPATH and Make):
1152 (VPATH and Double-colon, $< in Explicit Rules):
1153 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1154 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1155 New nodes, resulting from splitup of Limitations of Make.
1156 All cross-references changed. Raise the top node from
1157 a section to a chapter, and all subnodes accordingly.
1158 Redo the introductory wording to match the new organization.
1159 (Installation Directory Variables): Use an example that is
1160 closer to what Autoconf actually does. Mention that VPATH's
1161 value should not contain metacharacters or white space.
1162 (Fortran Compiler): Fix a VPATH bug in an example.
1163 (Leading _ in Macro Names): Mention that this problem is no longer
1164 of practical concern.
1165 (VPATH and Make): Reword the advice to make it clearer
1166 that Autoconf and Automake support VPATH in non-GNU make, but
1167 many packages have bugs in this area.
1168 ($< in Explicit Rules): Refer to Build Directories rather
1169 than using a (non-VPATH-safe) example.
1170 (Automatic Rule Rewriting): Mention the sort of disaster that
1171 can ensue with Solaris-style rule rewriting with VPATH.
1173 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1175 * doc/install.texi (Compilers and Options): Weaken the
1176 suggestion to use GNU make for VPATH builds.
1178 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1179 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1181 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1182 in regular expression.
1184 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1186 * doc/autoconf.texi (Installation Directory Variables):
1187 Drop extra @samp from `@table @samp' item.
1188 (Limitations of Usual Tools): Comment fix.
1189 Do not nest @samp just to point to other table items.
1190 (Writing testsuite.at) <AT_CHECK>: The second argument to
1191 `@dvar' is already @samp'ed.
1192 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1193 do not use @var in the second argument.
1195 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1197 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1198 $as_shell.exe too. Problem reported by Andreas Buening in
1199 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1201 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1203 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1204 `unused variable' compiler warning, for `-Wall -Werror'.
1205 Reported by Jaap Haitsma in
1206 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1208 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1210 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1211 case the compiler dumps core. Problem reported for
1212 OpenServer 5.0.7 by Tim Rice in
1213 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1214 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1215 Likewise.
1217 2006-06-06 Tim Rice <tim@multitalents.net>.
1219 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1220 "ERROR" only shows up in "make check" output if there is an
1221 error.
1223 2006-06-06 Eric Blake <ebb9@byu.net>
1225 * tests/tools.at (automatically allowed tokens): Fix typo.
1227 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1229 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1231 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1232 typically overflows on x86 CPUs, even though the C standard
1233 requires otherwise.
1235 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1237 * configure.ac (AC_INIT): Bump to 2.59e.
1238 * NEWS: Update.
1240 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1242 Version 2.59d.
1244 * config/texinfo.tex: Sync from upstream.
1246 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1247 seen, invoke libtoolize with `--ltdl' argument.
1248 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1249 * NEWS: Update.
1250 Suggested by Eric Blake.
1252 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1254 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1255 reported by Ralf Wildenhues.

1271 * tests/base.at: Check AC_REQUIRE's error message.
1272 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1273 to...
1274 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1275 AT_CHECK_M4.
1276 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1277 `expout' as the last parameter.
1278 * tests/tools.at: Adapt to the above change.
1280 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1282 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1283 information about race-free implementations of mkdir.
1285 2006-06-04 Eric Blake <ebb9@byu.net>
1287 * bin/autoreconf.in (help): Document M4 environment variable.
1288 * bin/autoconf.as (Usage): Likewise.
1289 * bin/autom4te.in (help): Likewise.
1290 * doc/autoconf.texi (autom4te Invocation): Likewise.
1292 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1294 * NEWS: GNU make now recommended for VPATH builds.
1295 Mention that some macros are now documented to be obsolescent.
1296 * doc/autoconf.texi:
1297 Prefer "current" to "modern" to describe
1298 currently-used (albeit perhaps old-fashioned) hosts.
1299 Mention which ancient features no longer need to be worried about.
1300 setgid -> set-group-ID
1301 setuid -> set-user-ID (these are the Posix terms)
1302 Fix some misuses of "only".
1303 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1304 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1305 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1306 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1307 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1308 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1309 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1310 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1311 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1312 Mention that these macros are obsolescent.
1313 (Installation Directory Variables): shall -> should
1314 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1315 Mention that it's now safe to use 3 and 4.
1316 (Limitations of Usual Tools): cp -r is now specified by Posix.
1317 Omit longwinded and obsolescent discussion of cp -f.
1318 Modernize discussion of expr, ls.
1319 (Limitations of Make): Modernize discussion of VPATH builds.
1320 Mention $? as a workaround in some cases.
1321 * doc/install.texi (Basic Installation):
1322 Mention "./configure; make; make install" first. Be more
1323 specific about why this file is generic. Remove unnecessary
1324 parens. Remove misleading "only". Remove obsolete advice
1325 about csh. Don't say "configure" takes awhile; say it
1326 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1327 and CC=c99 rather than CC=c89, as these are blessed by current
1328 Posix. Recommend GNU make if doing a VPATH build.
1330 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1332 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1333 examples involving shell prompts.
1335 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1336 and Paul Eggert <eggert@cs.ucla.edu>
1338 * doc/autoconf.texi (Here-Documents): Add details about the
1339 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1340 use "here-documents" instead of "here documents".
1342 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1344 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1346 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1348 * doc/autoconf.texi (File System Conventions): Warn about ":"
1349 anywhere in directory names.
1351 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1353 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1354 about quoting the case statement, just in case.
1355 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1356 was fixed in ksh93g; reported by Ralf Wildenhues.
1358 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1360 * doc/autoconf.texi (System Services): Do not document
1361 overriding EXEEXT via ac_cv_exeext=ext.

1363 Document that ${MKDIR_P} understands --.
1364 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1365 comment.
1367 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1369 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1370 argument with leading hyphen. Problem reported by Paul Eggert.
1372 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1374 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1375 about quoting ac_try: quote all of it, if any of it seems suspicious.
1376 This means we don't have to worry about ${ or sed any more.
1377 Also, double-quote the case statement, to work around misuses via
1378 underquoting as reported by Ralf Wildenhues in
1379 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1380 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1381 undocumented and dangerous macro.
1382 Problem reported by Ralf Wildenhues in
1383 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.

1389 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1391 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1393 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1394 since evidently some packages rely on the old, broken behavior.
1395 Problem reported by Ralf Wildenhues in
1396 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1397 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1398 pre-2006-05-26 definitions, but leave in the comments that
1399 these macros are dangerous and should not be used.
1400 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1401 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1402 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1403 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1404 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1406 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1408 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1409 the use of 'tr', since this is our only use of 'tr'.
1411 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1412 and Paul Eggert <eggert@cs.ucla.edu>
1414 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1415 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1417 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1419 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1420 the output file in the `${datarootdir}' test.
1422 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1423 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1425 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1426 mention of `datarootdir' in the input file(s), but literal
1427 `${datarootdir}' in the output file, and we haven't warned yet,
1428 then warn as well: the user may have (erroneously) used
1429 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1430 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1431 * tests/torture.at (datarootdir workaround): Extend this test.
1432 * NEWS: Update.
1434 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1435 and Paul Eggert <eggert@cs.ucla.edu>
1437 * doc/autoconf.texi (autoheader Invocation): The first argument to
1438 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1439 alternatives and clear up the language a bit.
1441 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1443 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1444 ac_config_guess, ac_config_sub, ac_configure.
1445 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1446 Fix typo that prevented an unnecessary space from being removed.
1447 Problems reported by Ralf Wildenhues in:
1448 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1450 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1452 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1453 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
1454 Don't use the term "thread-safe" to talk about mkdir race
1455 conditions, since the problem is more a process than a thread
1456 issue. Problem reported by Stepan Kasal in:
1457 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
1458 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
1459 the test for 'install' more closely. Look at MKDIR_P first.
1460 Look in the PATH, and at /opt/sfw/bin.
1461 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1462 Don't bother to try mkdir -p, since we already check mkdir --version;
1463 just look at the version number. (There's no easy way to check
1464 for race-free implementations.)
1465 * tests/tools.at (autoconf: subdirectories): Adjust to above
1466 changes, since MKDIR_P now might end in "/mkdir -p".
1468 * doc/autoconf.texi (autoheader Invocation): Mention that the
1469 first arg of AC_DEFINE_UNQUOTED must be a literal.
1470 Problem reported by Ben Pfaff in
1471 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1473 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1474 * doc/autoconf.texi (Special Chars in Variables): New section.
1475 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1476 (Installation Directory Variables): Quote $(datadir) better.
1477 (Limitations of Builtins): Describe some of eval's trickiness.
1479 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1480 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1481 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1482 in front of every arg, not just trailing args. Quote apostrophes.
1483 (_AC_EVAL_ECHO): New macro.
1484 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1485 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1486 removed.
1487 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1488 exposed by quoting of eval argument. Put the command on line line
1489 so it logs better.
1490 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1491 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1492 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1493 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1494 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1495 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1496 Use eval more safely.
1497 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1498 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1499 to be replaced.
1500 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1501 lines, exposed by quoting of eval argument.
1503 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1504 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1506 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1507 initialization of `ac_cv_exeext', do not override it if it was
1508 already set, unless it was set to `no', for compatibility with
1509 Autoconf-2.13, and comment this.
1510 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1511 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1512 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1513 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1514 Document that this test may be overridden by setting
1515 `ac_cv_exeext'.
1517 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1519 Revert these two patches:
1521 2006-04-06 Eric Blake <ebb9@byu.net>
1522 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1523 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1524 2006-04-01.
1526 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1527 Clean up _AC_COMPILER_EXEEXT* macros.
1528 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1529 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1530 ac_file to the name of the default output file and call
1531 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1532 initial `rm' of the candidate files...
1533 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1534 the same list in subsequent `rm' calls, and for the temporary
1535 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1536 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1537 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1538 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1539 no longer needed) by libtool. Make it a cache check.
1540 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1541 copied here by mistake.
1542 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1543 _AC_COMPILER_EXEEXT.
1544 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1545 _AC_COMPILER_OBJEXT directly.
1546 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1548 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1550 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1551 Fix description of how the buggy `sed' works.
1553 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1555 Sync from Automake:
1557 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1558 ENOLCK. Only mention `make -j' when applicable. Only raise
1559 fatal errors when `make -j' is involved. Improve error message.
1561 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1563 * doc/autoconf.texi (Here-Documents): We now know more about
1564 the variable expansion in here documents bug.
1565 Thanks to Tim Rice and Stepan Kasal.
1567 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1568 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1570 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1572 * tests/autotest.at (Multiline command from M4 expansion):
1573 No failure to be expected if the shell quotes newlines in
1574 commands in the `set -x' output. Report by Tim Rice.
1575 * THANKS: Update.
1577 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1579 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1580 expansion in the here-documents used by config.status, as that
1581 runs afoul of the Korn shell version M-12/28/93d bug described in
1582 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1583 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1584 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1586 2006-05-23 Jim Meyering <jim@meyering.net>
1588 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1589 Fix typo introduced with 2006-04-02 change. It reversed the sense
1590 of the test.
1592 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1594 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1595 ac_dB slightly, to save bytes in the script.
1596 Max out at 50 lines, rather than 96; this is more likely
1597 (though not guaranteed) to avoid obscure 'sed' failures.
1599 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1601 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
1602 `tr -d -' as bad option argument. Work around this by deleting
1603 an unrelated character.
1604 Report by Tim Rice <tim@multitalents.net>.
1606 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
1607 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1608 Stepan Kasal <kasal@ucw.cz>
1610 * doc/autoconf.texi (Particular Programs): Do not promise that
1611 we always prefer the GNU version of the program, and that we
1612 search according to PATH; both rules can have exceptions.
1613 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
1614 AC_PROG_SED. Move descriptions of limitations
1615 to the Limitations of Usual Tools section.
1616 (Limitations of Usual Tools) <sed>: Mention script length
1617 limitations with Solaris /usr/ucb/sed.
1618 <grep>: Fix wording for empty alternative. Mention that -c and
1619 -l should not be combined, and that -E and -F should not be
1620 combined.
1622 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1623 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1625 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
1626 limits in Solaris 8 /usr/ucb/sed by testing a long script.
1628 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1630 * doc/autoconf.texi (Defining Symbols): Literal parameter of
1631 AC_DEFINE is now passed to m4_pattern_allow.
1632 * NEWS: Mention that; likewise for AC_SUBST.
1633 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
1634 the parameter to m4_pattern_allow.
1635 * tests/tools.at: Add a check for that.
1637 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1639 * lib/autoconf/status.m4: Fix typos.
1641 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1643 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1644 only the files that this macro generates.
1646 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1648 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1649 the HP-UX sed limitation of 99 commands, labels do not count.
1650 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1651 in the comment.
1652 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1654 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1656 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1657 Import the following fix from coreutils:
1659 2006-01-13 Jim Meyering <jim@meyering.net>
1661 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1662 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1663 not double-quote uses of that variable, to accommodate the rare
1664 case in which getmntent is available in none of the libraries
1665 checked. This happens at least on FreeBSD 5.0.
1667 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1669 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
1670 ac_config_guess, ac_config_sub, and ac_configure, since evidently
1671 some other programs unwisely rely on these undocumented vars.
1672 But put in warning comments about them.
1673 Problem reported by Ralf Wildenhues in
1674 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
1675 * NEWS: Document that these variables are intended to go away.
1677 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1679 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
1680 and set the language to C++ (analogous to the equivalent Fortran
1681 tests).
1683 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
1684 * doc/autoconf.texi (C++ Compiler): Document it.
1685 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
1686 * NEWS: Update.
1688 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1690 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
1691 that caused config.status to generate 100-command sed scripts; the
1692 portable limit is 99.
1694 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1696 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
1697 variable `ac_d' instead of `d' to avoid infringing namespace.
1698 Report by Ralf Menzel.
1700 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
1702 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
1703 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
1704 * tests/tools.at (autoconf: subdirectories): New test, taken from
1705 the corresponding problem report by Ralf Wildenhues in:
1706 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
1708 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
1709 Quote some uses of shell variables if they might suffer unexpected
1710 globbing. This doesn't fix all instances of quoting problems that
1711 I found, just the easy ones that look safe.
1712 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
1713 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
1714 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
1715 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
1716 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
1717 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
1718 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
1719 Likewise.
1720 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
1721 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
1723 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1725 * bin/autoreconf.in ($help): Reword according to the manual.
1726 Suggested by Olly Betts.
1728 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
1729 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1731 * bin/autoreconf.in: Pass the directory argument to
1732 `require_configure_ac'. Fix comment.
1733 * tests/torture.at (Configuring subdirectories): Expose this.
1734 Reported by Olly Betts.
1736 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1738 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
1739 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
1740 Automake as follows:
1742 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
1743 `$configure_in' instead of `configure.in', to preserve
1744 directory component.
1746 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1748 * config/config.guess, config/config.sub, config/texinfo.tex,
1749 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
1751 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1753 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
1754 test for C99 conformance; (bool) 0.5 is an integer constant
1755 expression, but (bool) -0.5 is not. Problem reported by Fedor
1756 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
1758 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1760 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
1761 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
1762 Warn about obsolete install-sh files. Remove stray sentence
1763 fragment and fix cross reference.
1764 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
1765 install -d; this undoes the 2006-05-10 change.
1766 (MKDIR_P): Mark with AN_MAKEVAR.
1767 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
1768 that we don't require $INSTALL to be thread-safe. Move comments
1769 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
1770 of AC_PROG_INSTALL. Output a message saying that we're checking
1771 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
1772 MKDIR_P instead of AC_SUBST.
1773 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
1774 Special magic for MKDIR_P, too.
1775 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
1776 a dnl.
1777 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
1779 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1781 Sync from Automake, as follows:
1783 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1784 * config/install-sh: Initialize IFS, so field splitting isn't
1785 turned off later.
1786 * config/mkinstalldirs: Likewise.
1787 * config/missing: Remove superfluous quotes. Replace all uses of
1788 `[' by `test', for consistency, and for..
1789 * config/missing (sed_minuso, sed_output): New variables.
1790 (autom4te, help2man, makeinfo): Use them. Unifies detection of
1791 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
1792 Fixes `missing' to detect `--output' for help2man. Fixes
1793 PR automake/483. Report by Dennis J. Linse.
1794 (autom4te): Document in `missing --help'.
1796 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1798 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1799 * config/install-sh: Don't use 'path' to talk about file names,
1800 as per GNU coding standards. Close a race condition reported by Ralf
1801 Wildenhues and Stepan Kasal. There is still a race condition
1802 on hosts that predate Posix 1003.1-1992, but we can't help this.
1803 Don't mishandle weird characters like space on pre-Posix hosts.
1804 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1805 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1806 AC_PROG_MKDIR_P from AS_MKDIR_P.
1807 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1808 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1809 earlier editions are not (including Automake 1.8.3).
1810 Do not suggest mkinstalldirs for thread-safety.
1811 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1812 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1813 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1814 presence of special characters and race conditions.
1815 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
1816 in Autoconf's name space.
1818 2006-05-10 Bruno Haible <bruno@clisp.org>
1819 and Paul Eggert <eggert@cs.ucla.edu>
1821 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
1822 from Automake with minor changes.
1823 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
1825 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1827 * config/install-sh: Update to Automake CVS version, as follows:
1828 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1829 * lib/install-sh: Simplify the expr implementation of dirname.
1830 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
1831 * lib/install-sh: Handle --, and diagnose unknown options.
1833 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1835 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
1836 `./autom4te' to create `./testsuite', since the `all' target
1837 will ensure its presence, but `installcheck' should not create
1838 the uninstalled wrappers.
1840 * tests/torture.at (Unusual Automake input files): Skip if we
1841 detect automake < 1.8.
1843 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1845 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
1846 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
1847 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
1848 * NEWS: Update.
1850 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1852 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1853 munge (multiple) white space and other oddities.
1854 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1855 single quotes in variable assignment.
1856 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1857 and similar failures by adding multiple spaces, tabs, and other
1858 special characters.
1859 Report and different test suggested by Francesco Romani
1860 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1862 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1863 single quotes, we only need to search for single quotes; this
1864 both simplifies the search pattern, and makes us less
1865 susceptible to `echo' variations for arguments not containing
1866 single quotes.
1867 (_AC_ARG_VAR_VALIDATE): Likewise.
1869 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1871 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1872 `$*' and IFS concatenation issue with traditional shells and
1873 bash-2.04. Report by Seanster@Seanster.com.
1875 2006-05-03 Bruno Haible <bruno@clisp.org>
1877 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1878 precisely which Mac OS X versions have the od problem.
1880 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1882 * doc/autoconf.texi: Use @option systematically.
1884 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1885 and Bruno Haible <bruno@clisp.org>
1887 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1888 about 'od'.
1889 (Integer Overflow): Mention the special case of integer division
1890 overflow.
1892 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1894 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1895 traditional shells like the Solaris one that do not use the
1896 first IFS character for assembling `$*'.
1897 Prompted by a related report from autoconf_bug@nro.ca.
1899 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1900 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1902 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1903 Mention more problems with the -e option.
1905 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1907 * NEWS: Typo.
1908 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.

1911 in URLs to improve DVI formatted output (requires texinfo 4.6).
1912 (System Services, Systemology, Shellology): Likewise.
1913 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1914 output.
1916 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1917 continuous text.
1918 (Runtime): Fix macro argument names to match description:
1919 `action-if-found' -> `action-if-true' and similarly.
1920 (Obsolete Macros): Likewise.
1921 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1922 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1923 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1925 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1927 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1929 * ChangeLog: Typo.
1930 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1931 DVI output.

1943 (Integer Overflow, Null Pointers, Buffer Overruns):
1944 (Floating Point Portability, Exiting Portably): New sections.
1945 (Writing Test Programs): Fix some langauge. Recommend exiting
1946 with status 1, not merely nonzero. Clarify exit declaration.
1947 (Run Time): Move C exit status stuff to new Exiting Portably section.
1948 (Systemology): Mention Posix and levenez. Update v7 reference.
1949 (Portable Shell): Mention the Posix shell.
1951 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1953 * bin/autoconf.as (me): Replace by as_me.
1955 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1957 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1958 since as_me isn't set yet.
1960 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1962 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1963 a few minor bugs in this area.
1965 * doc/autoconf.texi (Programming in M4sh): Comment out the
1966 documentation of AS_BASENAME, for now.
1967 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1968 (Limitations of Builtins) <basename>: Do not refer to
1969 AS_BASENAME.
1970 * bin/autoconf.as (me): Don't use AS_BASENAME.
1971 (dir): Remove the unused variable.
1972 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
1973 AS_DETECT_REQUIRED. All uses changed.

1975 All uses changed.
1976 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
1977 (AS_BASENAME): Use "basename --" to protect against leading "-".
1978 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
1979 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1980 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
1981 (_AS_DIRNAME_PREPARE): Likewise.
1982 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
1983 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
1984 (AS_DIRNAME): Use "dirname --".
1986 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1988 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1989 of "run time" and "run-time" changed to "runtime", for consistency.

1991 * lib/autoconf/functions.m4: Likewise.
1992 * lib/autoconf/general.m4: Likewise.
1993 * lib/autoconf/headers.m4: Likewise.
1995 * doc/autoconf.texi (Run Time): Document the exit status situation
1996 with more accuracy and detail.
1998 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2000 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2001 Archive is not officially `GNU' any more. Update URL.
2002 (Defining Directories): Likewise
2003 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2005 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2007 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2008 newline from the `trap' code to finish `config.log'; the NetBSD
2009 /bin/sh resets the exit status after an empty command, as
2010 documented in doc/autoconf.texi.
2011 Reported by Dalibor Topic <robilad@kaffe.org>.
2013 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2015 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2016 Suggested by Bruno Haible.
2018 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2020 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2021 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2022 Instead, just list the shells that we know work.
2023 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2024 changed. Be more cautious about the _cv_ variable.
2025 * tests/tools.at (Syntax of the shell scripts): Check the
2026 _cv_ variable once, at first, to avoid an internal autoconf error
2027 when sh -n does not work.
2029 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2031 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2033 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2035 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2036 use ">&-" since we're only 99.999% sure that this is portable,
2037 and since the MinGW bug is fixed in a different way.
2038 * lib/autotest/general.m4 (AT_INIT): Likewise.
2040 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2042 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2043 before opening config.log, to avoid hitting a bug on MinGW.
2045 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2047 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2048 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2049 This works around a MinGW bug reported by Eric Paire.
2050 Make sure that all writes to the log file append to it,
2051 rather than possibly losing data.
2052 * lib/autotest/general.m4 (AT_INIT): Likewise.
2054 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2056 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2057 description.
2059 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2061 * NEWS: Update.
2063 * configure.ac (AC_INIT): Bump to 2.59d.
2065 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2067 Version 2.59c.
2069 * Makefile.maint (news-date-check): Do not require a leading `*'
2070 before the release date in NEWS.
2072 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2073 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2075 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2076 the instantiated file do not contain the string 'datarootdir'
2077 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2078 @mandir@, replace the reference '${datarootdir}' by the value.
2079 * tests/torture.at (datarootdir workaround): New test.
2080 * NEWS: Advertise this temporary fixup.
2081 Based on a patch by Bruno Haible, reported and analyzed by
2082 Paul Eggert and Noah Misch.
2084 2006-04-12 Eric Blake <ebb9@byu.net>
2086 * tests/autotest.at (Debugging a failed test): Fix comment.
2088 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2090 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2091 all the changes since 2006-04-07.
2093 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2095 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2096 succeeded, but `ln -s file dir' failed, take care to remove the
2097 leftover target before the next test, to prevent its spurious
2098 failure; also make sure `ln file dir' works before selecting it.
2099 Thanks to Keith Marshall for pointing this out.
2100 * THANKS: Update.
2102 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2103 assignments in `at_debug_args', so that we put them correctly
2104 in the `run' script.
2105 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2106 Reported by Eric Blake.
2108 2006-04-11 Eric Blake <ebb9@byu.net>
2110 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2111 top-level tests after micro-suite has been run. Used in...
2112 (Debugging a successful test, Debugging script and environment),
2113 (Debugging a failed test): ...these new tests. The first of these
2114 is fixed by...
2115 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2116 macro, split out from...
2117 (AT_INIT): ...here, so that using -d also generates a run script.
2118 Document that -d inhibits top-level logging.
2119 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2120 inhibits top-level logging; debug scripts are created.
2122 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2123 check.
2124 * tests/autotest.at (Empty test, Empty check): New test to check it.
2126 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2127 from gcc.
2129 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2131 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2132 the files if a problem appears. Make the empty *.at files
2133 read-only, too. Proposed by Ralf Wildenhues.
2135 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2137 * config/Makefile.am: Add comment to force updated Makefile.in.
2139 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2140 space only patch to this file, this patch causes the Makefile.in
2141 files that include freeze.mk to be updated, and thus have a
2142 newer time stamp again, which in turn makes a pristine CVS
2143 checkout have correct time stamps.
2145 * Makefile.maint (cvs-sv): New macro, to be used..
2146 (config.guess-url_prefix, config.sub-url_prefix)
2147 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2148 point to CVS text checkout of Gnulib files.
2149 (copyright-check): Bump current year.
2150 (announcement): Do not hard-wire `./announce-gen'.
2151 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2152 correctly.
2153 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2154 `chmod +x'.
2155 (wget_files): Update config.guess, config.sub, texinfo.tex by
2156 `wget-update', now that their URLs work again.
2158 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2160 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2161 Problem noted by Paul D. Smith.
2163 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2165 * doc/autoconf.texi: Remove unused words from word list.
2166 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2167 .x-sc_trailing_space: New files.
2169 * doc/standards.texi: Sync from gnulib.
2171 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2172 `LIBOBJDIR' as experimental.
2174 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2175 with a target directory; it's internally implemented as `cp'
2176 anyway, but since Autoconf advertises the possibility to use
2177 a target directory when LN_S is `ln -s', we need to find out.
2178 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2179 analyzed by Keith Marshall <keith.marshall@total.com>.
2181 * THANKS: Update.
2183 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2185 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2186 confdefs.h as-is. In general, if it has backslash-newline or the
2187 like, then it doesn't work either to sort or to remove empty
2188 lines.
2190 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2192 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2194 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2196 * lib/autom4te.in (Automake-preselections): Preselect
2197 _AM_SUBST_NOTMAKE.
2199 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2201 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2202 apostrophe within a single-quoted string, as this is the usual
2203 tradition and is easier to read than '"'"'. Don't rely on the
2204 shell treating "$/" like '$/'. Use a more-consistent indenting
2205 style for the trap.
2207 2006-04-09 Eric Blake <ebb9@byu.net>
2209 * tests/autotest.at (Backquote command substitution),
2210 (Multiline backquote command substitution): Remove mistaken
2211 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2212 applied...
2213 (Parenthetical command substitution, Multiline parenthetical
2214 command substitution): here.
2216 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2218 Import macros from gnulib (often changing their name).
2220 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
2221 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
2222 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

2232 (Pointers): Add Gnulib URL.
2233 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
2234 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
2235 Gnulib section.
2236 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
2237 suggest a #define rather than a typedef for _Bool, and mention
2238 Gnulib rather than trying to substitute stdbool code.
2239 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
2240 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
2241 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
2242 AC_STRUCT_DIRENT_D_TYPE.
2243 (Particular Types): Mention stdint.h and inttypes.h as standard
2244 headers too.
2245 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
2246 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2247 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2248 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2249 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2250 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2251 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2252 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2253 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2254 (Coding Style). Don't mention m4_expand_once.
2255 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
2256 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
2257 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
2258 (AC_CHECK_FUNCS): Use it.
2259 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
2260 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".

2262 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
2263 (AC_HEADER_ASSERT): New macro.
2264 (AC_HEADER_STDBOOL): Don't assume "#error" works.
2265 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
2266 Catch a bug in an HP-UX C compiler.
2267 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
2268 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
2269 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

2271 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
2272 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
2273 New macros.
2275 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not

2289 that contains braces.
2291 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2293 Revert the patch from 2006-04-01 and only improve
2294 _AS_DETECT_BETTER_SHELL:
2296 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2297 skip nonexistent directories.
2298 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2299 only shell candidates which exist.
2300 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2301 * lib/autotest/general.m4 (AT_INIT): No need to give three
2302 parameters to _AS_PATH_WALK.
2304 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2305 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2307 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2308 distinguish m4sugar macros.
2309 * tests/tools.at (autoupdating with aclocal and m4_include):
2310 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2311 test case by Noah Misch <noah@cs.caltech.edu>.
2313 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2315 Revert my change from 2006-03-17, in other words:
2316 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2317 and DUALCASE=1.
2318 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2319 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2320 it is set.
2322 2006-04-07 Eric Blake <ebb9@byu.net>
2324 * doc/autoconf.texi (Programming in M4sh): Document that
2325 AS_MKDIR_P exits the script on failure.
2326 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2328 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2330 * config/elisp-comp, config/install-sh, config/mdate-sh,
2331 config/missing, config/mkinstalldirs: Sync from Automake.
2333 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
2334 from Automake.
2336 * doc/make-stds.texi: Sync from gnulib.
2338 2006-04-06 Eric Blake <ebb9@byu.net>
2340 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2341 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2342 2006-04-01.

2345 Eric Blake <ebb9@byu.net>,
2346 Paul Eggert <eggert@cs.ucla.edu>,
2347 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2349 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2350 whether `set' quotes correctly: redirect stderr of the tested
2351 `set', and use a subshell, for Ultrix; use `sed' instead of
2352 `grep' for zsh `set' which may write binary output; match only
2353 at the beginning of a line, to avoid false positives.
2354 In order to avoid false positives by unrelated variables with
2355 multiline content, put the dump algorithm in a subshell and
2356 unset all variables containing newlines (except some which are
2357 special to the shell). Warn about cache variables that are
2358 unset.
2360 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2362 * config/config.guess, config/config.sub, config/texinfo.tex:
2363 Sync from upstream.
2365 * tests/mktests.sh: Reword comments.
2367 * tests/mktests.sh: Only skip internal macros starting with
2368 `_AC_' or `__AC_'. Noted by Stepan Kasal.

2370 (AC_ARG_VAR): Do test this now.
2371 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
2372 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
2373 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
2374 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
2376 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
2377 shell issue with double-quoted command substitutions of native
2378 commands.
2379 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
2380 Marshall.
2382 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

2395 <tab><space> where this makes sense.
2397 2006-04-06 Stepan Kasal <kasal@ucw.cz>
2399 * tests/Makefile.am (maintainer-check-posix):
2400 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
2402 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
2403 ac_config_<foo>s again, sometimes normalized, sometimes not.
2404 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
2405 (AC_CONFIG_COMMANDS): Do not do so here.
2406 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
2407 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
2408 2005-07-25 rewrite. Noticed by Noah Misch.
2410 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
2411 _AC_PRESERVE_HELP_ORDER, ...
2412 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
2414 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
2415 inside m4_expand_once; it is redundant.
2417 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
2418 for --help from Cygnus `configure.'
2420 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

2423 on a patch proposed by Ralf Wildenhues.
2425 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2427 * lib/autoconf/status.m4: Replace <space>''<tab> with
2428 <tab><space> where this makes sense.
2430 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
2431 Noah Misch <noah@cs.caltech.edu>
2433 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
2434 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
2435 * doc/autoconf.texi (Help Formatting): New node.
2436 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
2438 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2440 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
2441 lib/autoconf/specific.m4, lib/autoconf/status.m4,
2442 lib/autoconf/types.m4, lib/autotest/general.m4,
2443 tests/mktests.sh, tests/torture.at: White space cleanup:
2444 remove some SPACE before TAB, or add quoting ('' or @&t@).
2446 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
2448 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
2450 2006-04-05 Eric Blake <ebb9@byu.net>
2452 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
2453 empty test suite works.
2454 * tests/autotest.at (Empty test suite): Remove xfail.
2456 2006-04-05 Noah Misch <noah@cs.caltech.edu>
2458 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
2459 TAGS to ac_config_<foo>s.
2460 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
2461 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
2462 normalizing it, consistent it with previous releases.
2463 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
2465 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2467 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
2468 Use simplified args that Eric Blake originally suggested.
2470 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
2472 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
2473 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
2474 Use 'comm' rather than N instances of grep; this also fixes a bug
2475 whereby substrings were incorrectly matched, causing us to not
2476 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
2477 (exclude_list): Exclude empty macros.
2478 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
2480 Use awk rather than grep -E or egrep, to avoid
2481 portability problems with regular expressions containing newlines.

2483 Switch from grep to awk syntax.
2484 (ac_exclude_script): Renamed from ac_exclude_egrep.
2485 (au_exclude_script): Renamed from au_exclude_egrep.
2487 2006-04-04 Noah Misch <noah@cs.caltech.edu>
2489 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
2490 a subdirectory subject to Cygnus `configure'.
2491 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
2493 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
2494 report request when we have no AC_PACKAGE_BUGREPORT.
2496 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2498 * THANKS: Update.

2501 generated files.
2503 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
2504 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
2505 typedef'ed restricted pointer, to catch a compiler bug on
2506 HP-UX 11.x, and fix warnings so it passes with -Werror.
2507 (_AC_PROG_CC_C99): Likewise.
2508 Reported by Albert Chin <china@thewrittenword.com>.
2509 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

2524 * THANKS: Add myself.
2526 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2528 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
2529 to log, point to testsuite output tree.
2531 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
2533 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
2534 * doc/autoconf.texi (Function Portability): Mention that C++
2535 has trouble with 'exit'.

2538 Remove; all uses removed.
2539 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

2559 Clean up _AC_COMPILER_EXEEXT* macros.
2561 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2562 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2563 ac_file to the name of the default output file and call
2564 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2565 initial `rm' of the candidate files...
2566 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2567 the same list in subsequent `rm' calls, and for the temporary
2568 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2569 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2570 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2571 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2572 no longer needed) by libtool. Make it a cache check.
2573 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2574 copied here by mistake.
2575 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2576 _AC_COMPILER_EXEEXT.
2577 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2578 _AC_COMPILER_OBJEXT directly.

2609 * lib/autoconf/general.m4 (_AC_INIT_VERSION): Emit script name and
2610 Autoconf version number despite a zero- or one-argument AC_INIT.
2612 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
2613 subordinate tools.
2614 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
2615 * doc/autoconf.texi (autoreconf Invocation): Document it.
2617 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
2618 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.
2620 2006-04-01 Eric Blake <ebb9@byu.net>
2622 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Allow use in shell lists.

2624 rm failed to remove it.
2626 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2628 * bin/autoupdate.in: Redefine m4_location so that warnings print
2629 the correct lines of the input file by subtracting..
2630 (_au__first_line): ..this new definition.
2632 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
2633 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
2634 Remove stray newline in output.
2635 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
2636 AC_DEFUN this for autoconf, including the obsoletion diagnose.
2637 Fixes autoupdating of code where the replacement output contains
2638 m4sugar macros.
2639 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
2640 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

2642 * tests/tools.at: Several new tests for all of this.
2643 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
2644 hairy details.
2645 The AC_LANG_SAVE issue was reported against Libtool by
2646 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
2647 Kristian Kvilekval <kris@cs.ucsb.edu>.
2649 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2651 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
2652 switch all of them on and of when necessary. Fixes the bug when
2653 m4sugar macros (e.g., m4_define) were expanded after the first
2654 automatic update (e.g., after AC_PREREQ or AC_INIT).
2656 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

2678 2006-03-30 Chris Pickett <cpicke@cs.mcgill.ca> (tiny change)
2680 * doc/autoconf.texi (autoreconf Invocation): Mention that -I for
2681 aclocal cannot be given on the command line.
2683 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
2685 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
2686 Give an example for AS_DIRNAME instead of referring to Posix..
2687 (File System Conventions): Put discussion of // versus / here, and
2688 modernize it a bit.
2689 (Limitations of Usual Tools): Add basename. Remove verbiage
2690 after dirname, since it got moved to the above sections.
2691 All this was inspired by a patch proposed earlier by Eric Blake.
2693 2006-03-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2695 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Quote

2697 * lib/autotest/general.m4 (AT_INIT): Likewise.
2698 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Likewise, for
2699 `$0', $as_me.
2701 2006-03-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2703 * bin/autoscan.in: The value of find_configure_ac should be
2704 checked for existence, so we don't barf over a nonexisting
2705 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
2707 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2709 * bin/autoupdate.in: Fix some typos.
2711 2006-03-21 Stepan Kasal <kasal@ucw.cz>
2713 * doc/autoconf.texi (Installation Directory Variables): Fix typo.
2715 * lib/autoscan/autoscan.list: Refreshed.
2717 2006-03-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3191 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer s/a/b/.
3192 (AC_OUTPUT_MAKE_DEFS): Likewise.
3193 * lib/autotest/general.m4 (AT_INIT): Likewise.

3198 and improve the sed-related documentation a bit.
3199 * doc/autoconf.texi (Installation Directory Variables): Use
3200 our own style advice re 's,a,b,' versus 's|a|b|'. Use "Sed"
3201 rather than "sed" when talking about Sed in general.
3202 (Particular Programs): Likewise.
3203 (Coding Style): y is like s with respect to / and ,.
3204 (Limitations of Usual Tools): Document the weird restrictions
3205 that Posix has about { }. Use better quoting.
3206 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_HEADER):
3207 Rewrite to conform to Posix rules about { } in sed scripts.

3226 shell from zsh to bash.
3228 2005-12-31 Stepan Kasal <kasal@ucw.cz>
3230 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Use $PATH_SEPARATOR;
3231 ":" caused problems on OS/2-EMX. Suggested by Andrew Belov.
3233 2005-12-29 Paul Eggert <eggert@cs.ucla.edu>
3235 * doc/autoconf.texi (Shell Substitutions): Warn about unbalanced
3236 parentheses in $(...). Problem reported by Eric Blake.

3268 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Pass
3269 CONFIG_SHELL in the environment of the configure rerun.
3270 * doc/autoconf.texi (Here-Documents, config.status Invocation):
3271 Suggest passing CONFIG_SHELL absolute, and in the environment
3272 rather than as option.

3288 ac_clean_files and LIBOBJS.
3290 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3292 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
3293 Factor functionality to..
3294 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
3295 `AC_SUBST($1)' in the public version.
3296 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
3297 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
3298 ac_pt_* variables.
3300 2005-11-01 Stepan Kasal <kasal@ucw.cz>
3302 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
3303 filesystems.

3312 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3314 2005-10-25 Stepan Kasal <kasal@ucw.cz>
3316 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
3317 conftst2.$ac_objext.
3318 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3320 2005-10-24 Stepan Kasal <kasal@ucw.cz>
3322 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
3323 conftest.o, to see whether the compiler really obeys; rm the object
3324 file before and after the test and register it with ac_clean_files.
3325 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3327 2005-10-21 Stepan Kasal <kasal@ucw.cz>
3329 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
3330 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
3331 code so that the most common case requires less forks.
3333 2005-10-20 Stepan Kasal <kasal@ucw.cz>
3335 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is

3343 the latter'', in two places.
3345 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
3347 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
3348 AC_LANG_PROGRAM, fixing a typo. Don't give details about
3349 the inner workings of AC_LANG_FUNC_LINK_TRY.
3350 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
3351 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
3352 by the function rather than ignoring it.
3353 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
3354 comparing its address. Intel's interprocedural optimization was
3355 outsmarting the old heuristic. Problem reported by
3356 Mikulas Patocka.
3358 2005-10-19 Stepan Kasal <kasal@ucw.cz>
3360 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
3362 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
3364 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

3367 2005-10-04 Stepan Kasal <kasal@ucw.cz>
3369 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
3370 before removing it (chmod -R u+rwx); there are three instances of this.
3372 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3373 Stepan Kasal <kasal@ucw.cz>
3375 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3376 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3377 make its content writable before removing it. Remove an errorneous
3378 comment from the end, where the logs of the failed tests are copied
3379 to the main log file.
3381 2005-09-27 Stepan Kasal <kasal@ucw.cz>
3383 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
3384 in case the computer is too quick. Double quote the configure.ac
3385 snippets.
3387 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
3388 problems if the testsuite were running too fast.
3390 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3392 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3393 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3394 (which belong to Xt, not X itself). See Debian bug 327655.
3395 * NEWS: Mention this.
3397 2005-09-07 Stepan Kasal <kasal@ucw.cz>
3399 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
3401 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
3403 * config/move-if-change: Don't output "$2 is unchanged";
3404 suggested by Ben Elliston. Handle weird characters correctly.
3406 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3408 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3409 calls, so that the final expansion of this macro is shorter.
3410 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3411 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3412 the cleanup there. Use AS_VAR_* macros, to be more general.
3413 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3415 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3417 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
3419 2005-09-01 Stepan Kasal <kasal@ucw.cz>
3421 * doc/autoconf.texi (Configuration Headers): Add an index entry
3422 for AH_HEADER.
3424 2005-08-26 Pavel Roskin <proski@gnu.org>
3426 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
3427 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
3428 running xmkmf.
3430 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
3432 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3433 The previous patch didn't work, so try a better one.
3435 2005-08-26 Stepan Kasal <kasal@ucw.cz>
3437 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3438 in the example. Reported by Bruno Haible.
3439 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3440 "if $undefined_var;" succeeds with my shell.
3442 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
3443 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
3444 but change the m4_divert_text to m4_divert_once.
3446 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
3448 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3449 Work around bug in Solaris /usr/xpg4/bin/awk.
3450 The bug is present in at least Solaris 8 through 10.
3452 2005-08-24 Stepan Kasal <kasal@ucw.cz>
3454 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
3455 some evil values and relying on the fact that $* concatenates the
3456 parameters by the first character from IFS.
3458 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3459 Stepan Kasal <kasal@ucw.cz>
3461 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
3462 first header appears, define AH_HEADER.
3463 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
3464 Update limitations about when to call AC_CONFIG_HEADERS.
3465 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3466 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3467 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3468 ``Configuration Actions''; fix their index entries.
3470 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3471 options correctly. Process N-M as M-N if M is smaller than N.
3472 Process ranges correctly so that N-N will run only N.
3473 Sort and uniquify the tests that will be run. If there is more
3474 than one test, reinsert the banners for the tests.
3475 * tests/autotest.at (Keywords): Unmark XFAIL.
3477 2005-08-23 Stepan Kasal <kasal@ucw.cz>
3479 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
3480 before passing the macro name to AH_TEMPLATE.
3482 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3483 now opens log after option processing; in particular, --version
3484 and --help do not touch config.log.
3486 * Makefile.maint: Revert the change from 2005-08-12.
3488 2005-08-22 Stepan Kasal <kasal@ucw.cz>
3490 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
3491 common code to...
3492 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
3494 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3496 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
3497 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
3498 Language cleanup.
3500 * doc/autoconf.texi (Defining Symbols, Changed Results):
3501 Prepend to LIBS, not append, in examples.
3503 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3505 When building in place, set srcdir="."; suggested by Tim Van Holder.
3507 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3508 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3509 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3510 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
3511 does not mean "no --srcdir option".
3513 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3515 * tests/autoscan.at (autoscan): New file.
3516 * tests/suite.at: Use it.
3517 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
3518 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
3520 * tests/autotest.at (Keywords): Test keywords combinations.
3522 2005-08-12 Stepan Kasal <kasal@ucw.cz>
3524 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
3525 add "2>&1"; gzip 1.2.4 prints help on stderr.
3527 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3529 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
3530 was pushdef'ed twice while popped only once. Push it only once.
3531 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
3533 2005-07-26 Stepan Kasal <kasal@ucw.cz>
3535 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
3536 prefixed by mere "===", not "configure: === ".
3538 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
3540 * Makefile.maint: Update from Bison.
3542 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3543 "<tab>" in comment, so that the point is understandable.
3545 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3547 Rewrite substantial part of lib/autoconf/status.m4.
3548 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3549 and CONFIG_COMMANDS are not processed in four separate loops.
3550 Instead, there is one main loop. This alows that the common code
3551 is expanded only once, thus config.status (and configure) is smaller.
3553 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3554 the AC_LIST_FILES and cousins macros are no longer used.
3556 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3557 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3558 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3559 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3560 contain the initialization, nor the for loop, nor the associated
3561 commands; all these go to ...
3562 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3563 _AC_OUTPUT_CONFIG_STATUS.
3564 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3565 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3566 (_AC_OUTPUT_FILE): The creation of the sed script ...
3567 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3568 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3569 _AC_OUTPUT_MAIN_LOOP.
3570 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3571 _AC_CONFIG_COMMANDS): Use ...
3572 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3573 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3574 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3575 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3576 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3577 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3578 ... new macros.
3579 (_AC_CONFIG_UNIQUE): Update.
3580 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3581 Replaced by this ...
3582 (_AC_LIST_TAGS): ... new common macro.
3583 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3584 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3585 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3586 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3587 this didn't belong to the `config commands' section.
3588 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3589 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3590 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3591 to the `config commands' section either.
3592 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3593 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3595 ... and many changes to the comments nearby.
3597 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3598 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3599 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3600 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
3601 (#define header templates): The comment at the top of the generated
3602 header now includes the name(s) of the source file(s).
3604 Several unrelated small changes:
3606 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
3607 parameter to AC_DIAGNOSE.
3608 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
3609 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
3610 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
3611 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
3612 with AU::AC_OUTPUT.
3613 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
3614 in AC_OUTPUT doesn't double-quote it either.
3615 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
3616 parameters.
3618 2005-07-10 Stepan Kasal <kasal@ucw.cz>
3620 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
3621 versions of Portland Group compiler produce single- and double-quoted
3622 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
3623 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3625 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3627 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3628 This is a corrected version of yesterday's patch.
3630 2005-07-07 Stepan Kasal <kasal@ucw.cz>
3632 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
3633 path, too; insert a "===" to emphasize the line.
3635 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
3636 ac_cv_build_alias to ac_build_alias.
3637 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3639 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3640 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3641 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3642 (AC_ARG_VAR): ... here.
3643 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3644 target_alias.
3646 Keep a list of all precious variables and process them with one simple
3647 for loop, instead of expanding all commands, or, OTOH, complicated
3648 processing of output of "set".

3653 a loop to assign all ac_env_* and ac_cv_env_* variables.
3654 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3655 to INIT_PREPARE.
3656 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3657 its value to shell variable ac_precious_vars and call
3658 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.

3683 2005-07-05 Stepan Kasal <kasal@ucw.cz>
3685 Fix my changes from 2005-07-01; reported by Noah Misch.

3696 versions of autoconf.
3698 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
3700 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

3705 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
3706 sed substitution command, so that we allow | in program prefixes

3710 configure_input, top_builddir, srcdir, etc.
3711 * lib/autotest/general.m4 (AT_INIT): Likewise, for
3712 PATH_SEPARATOR in AUTOTEST_PATH.
3714 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

3722 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

3748 for --help in that case.
3750 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
3751 matches the order of execution. No code changed.

3773 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
3774 (AC_SUBST): Call it.
3775 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
3776 the directory specific variables; but don't call it for configure_input.

3780 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
3781 addition.
3783 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

3786 directory have inherent problems with special characters like spaces,
3787 due to limitations in Make syntax. Problem reported by Alexandre
3788 Duret-Lutz.

3805 because we really don't support spaces and suchlike in dir names.
3806 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3807 Don't worry about backslashes in srcdir; it can't happen now.

3835 b, t, r, w commands require single space, while : cannot have any.
3836 (Special Shell Variables): Fix sed code this in the example.
3837 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
3838 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
3840 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
3841 expand to the empty list. Don't use two pairs of m4_changequote,
3842 it's not necessary.

3850 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
3851 * doc/autoconf.texi:
3852 Don't mention Solaris versions so much, if a
3853 problem is common to all extant versions of Solaris. Say "SunOS
3854 4" instead of "SunOS" for SunOS 4.
3855 (awk): Mention more of the limitations of traditional Awk.
3856 (cat): Don't talk about cat -v.
3858 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

3863 to be compatible with glibc strverscmp.
3864 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
3866 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

3878 as per POSIX.
3879 * lib/m4sugar/m4sh.m4: Likewise.

3889 quotes and backslashes. Patch from Derek Price.

3894 AS_TR_SH.
3896 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
3898 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3899 -u, since it outputs chatter if the input files are the same.
3900 Problem reported by Ralf Menzel.
3902 2005-06-08 Derek Price <derek@ximbiot.com>
3904 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3905 renaming them since they are about to be redefined anyhow.
3907 2005-06-08 Derek Price <derek@ximbiot.com>
3909 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3910 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3911 Move m4_undefine to alphabetical order.
3913 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
3915 * README: Recommend GNU M4 1.4.3 or later.
3916 * doc/autoconf.texi (Introduction): Likewise.
3917 Reword to avoid some formatting glitches.
3918 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
3919 Clarify explanation of HP compiler bug.
3920 Redo example output tp match current CVS snapshot.
3921 Use @example.org in email addresses when the examples
3922 might get inadvertently cut-and-pasted into user code.
3923 Remove example of autom4te usage that doesn't seem to work now.
3924 Use modern AC_INIT (except when the example is meant to be
3925 shown with Autoconf 2.13).
3926 Update ksh info for Solaris 9 and later.
3927 KB -> kB.
3928 Modernize description of Automake versions a bit.
3929 Don't claim a future version of Autoconf is near.

3936 Reword to avoid some formatting glitches.
3937 * doc/installt.exi: Reword to avoid some formatting glitches.
3939 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3940 Tru64 ksh pattern matching bug. Reported against Libtool by
3941 Albert Chin <libtool@mlists.thewrittenword.com> and
3942 Nicolas Joly <njoly@pasteur.fr>.
3944 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3946 m4_cdr of one-member list was [[]] (one-member list containing an
3947 empty string) instead of [] (an empty list. Callers were skewed to
3948 match this misbehaviour. As a consequence of this:
3949 - m4_foreach([x], [], [foo]) expanded to `foo', while
3950 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3951 This bug has been fixed:
3953 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3954 expand to an empty string; print error msg if called without
3955 an argument list.
3956 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3957 misbehaviour; handle [] and [[]] correctly.

3965 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3967 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3968 swallow records with more than 99 fields.
3969 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3970 parse the long line.
3972 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3974 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3975 swallow literals longer than 399. Reported by Ralf Wildenhues.
3976 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

3987 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3988 (DISTCLEANFILES): Remove $(check_SCRIPTS).
3989 (testsuite): Make sure autotest.m4f is up-to-date before using it.

3993 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3994 expression of unbounded size when processing the --list
3995 option. This runs afoul of a limit of 399 bytes per regular
3996 expression on AIX. Problem reported by Ralf Wildenhues.

4009 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4010 now contain newlines, and substituted files must be referenced on
4011 a line alone; the sed scripts to substitute them are now very
4012 different.

4014 commands can be put in a sed script portably.
4015 * doc/autoconf.texi (Setting Output Variables): Document above

4028 classes in shell scripts. The test was too brittle.
4030 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4032 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4033 * doc/autoconf.texi (Limitations of Builtins): Document this
4034 limitation.
4036 2005-05-24 Stepan Kasal <kasal@ucw.cz>

4046 messages when ac_unique_file is not found.
4047 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4048 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo

4064 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4065 (ac_top_builddir): ... this ...
4066 (ac_top_build_prefix): ... to this; the old name is also kept, for
4067 backward compatibility.
4068 (ac_top_builddir_sub): New variable, without the trailing slash,
4069 always nonempty.
4070 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

4084 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4085 argument to m4_foreach. I guess it was necessary in the past,
4086 but I think it's a no-op now.
4088 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4090 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4091 ``cat <<_ACEOF'' commands to one.
4092 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''

4094 ``echo|sed.''
4095 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4096 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.

4099 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4100 the wrong patterns between ``case'' and ``esac.'' The previous
4101 code had false positives.
4103 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4105 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4106 as on 2005-05-02.
4107 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
4108 Mention LIBOBJDIR.

4148 2005-05-13 Stepan Kasal <kasal@ucw.cz>
4150 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
4151 check.
4152 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
4153 enough arguments, similarly as in m4_bpatsubsts.
4155 2005-05-12 Stepan Kasal <kasal@ucw.cz>
4157 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

4160 2005-05-11 Stepan Kasal <kasal@ucw.cz>
4162 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
4163 for absolute directory names in one loop.
4164 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
4165 abbreviations of --version and --debug.
4167 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
4169 * doc/autoconf.texi (Autoconf Language): Be more precise about
4170 quoting rules. Problems noted by Stepan Kasal.
4171 Also, throughout this document, be more careful about white space.
4172 "blank", "white space", and "space" all have different meanings
4173 and we should be careful to say what we mean.
4175 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4177 Fix C++ related problems reported by Werner Lemberg.
4178 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
4179 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
4180 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
4181 avoid problems with C++ and throw.
4182 * tests/compile.at: .cpp, not .cc.
4184 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
4186 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4188 * doc/autoconf.texi (Generic Functions): Typos.
4190 2005-05-02 Gary V. Vaughan <gary@gnu.org>
4192 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
4193 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
4194 set by latest automake.
4196 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4198 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
4199 outputs 0 on GNU/Linux these days.
4201 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4203 * doc/autoconf.texi (Autoconf Language): Add more description
4204 about quoting heuristics.
4205 (Limitations of Builtins): Describe "set -" problems.
4207 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4209 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4210 not newline.
4212 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4213 by AC_DEFINE; it was a mistake.
4214 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4216 2005-04-25 Stepan Kasal <kasal@ucw.cz>
4218 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
4220 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4222 * doc/autoconf.texi (External Software): Quadrigraphs are not
4223 processed correctly in AS_HELP_STRING; avoid this in the examples.
4224 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4225 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4226 comment and reduce m4_default([foo], []) to [foo].
4227 (m4_strip): Update the explanation.
4229 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4231 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4232 Remove core.conftest.* too; it's generated by Tru64 5.1.
4233 Problem reported by Jennis Pruett.
4234 * lib/autoconf/functions.m4
4235 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4236 Don't bother to remove core files; AC_RUN_IFELSE should do that
4237 for you.
4239 2005-04-19 Stepan Kasal <kasal@ucw.cz>
4241 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
4243 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>

4248 2005-04-15 Stepan Kasal <kasal@ucw.cz>
4250 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
4251 the comment.
4253 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
4255 * doc/autoconf.texi (External Software, Package Options): Add
4256 examples showing how to implement --with-* and --enable-* options.
4258 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
4260 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
4261 as well as configure.in. Problem reported by Gregorio Guidi.
4263 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
4265 * doc/autoconf.texi (Particular Functions): Use gnulib's current
4266 pattern for alloca snippet.
4268 2005-04-04 Stepan Kasal <kasal@ucw.cz>
4270 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

4276 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
4278 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
4279 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
4281 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4283 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4284 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4285 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4286 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4287 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4289 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4291 * NEWS: The configure command now warns you if you attempt to use
4292 a directory whose name contains a special character like space,
4293 newline, or "\".
4294 * doc/autoconf.texi (Installation Directory Variables): Allow
4295 "," in file names. Do not use \@; it's not a portable regexp.
4296 * bin/Makefile.am (edit): Likewise.
4297 * lib/Makefile.am (edit): Likewise.
4298 * tests/Makefile.am (edit): Likewise.
4299 * tests/semantics.at: Likewise.
4300 * tests/torture.at: Likewise.
4301 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
4302 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
4303 * doc/autoconf.texi (File System Conventions): Warn about
4304 unportable file names.
4305 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4306 (AC_INIT): Use it.
4307 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4308 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4309 ac_pwd, and quote srcdir.
4310 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4312 * doc/autoconf.texi: Fix some systematic formatting problems.
4313 ".)" needs a following @: if not at the end of a sentence, and
4314 similarly for "!)". "etc." should be preceded by a comma.
4315 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4317 2005-03-22 Bruno Haible <bruno@clisp.org>
4319 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4320 argument is often called 'build-aux'.
4322 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4324 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4325 macro AC_TRY_LINK is obsolete.
4326 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4327 `AC_CONFIG_FILES'.
4329 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4331 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4332 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4333 from a Common Lisp's `cl'.
4334 (AC_PROG_CXX): Behave according to the documentation: don't
4335 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4336 make the variable CCC precious; use `cl.exe', not `cl'.
4338 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4339 Alexandre Duret-Lutz <adl@gnu.org>
4341 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4342 /dev/null, as "configure" shouldn't read stdin, and this insulates
4343 us from problems (e.g., when testing for "cl"). Also, do this
4344 redirection before invoking "hostname" or "uname", and keep the
4345 original input stream available via...
4346 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4347 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4348 bother with "</dev/null" since it's now done at the top of
4349 'configure'.
4350 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4351 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4352 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4353 * doc/autoconf.texi (File Descriptor Macros): New section.
4354 (Printing Messages): Mention it.
4355 * tests/base.at (Input/Output): New test.
4357 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4359 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4360 newline if neither \c nor -n work, as that would output two
4361 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4363 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4365 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4366 This causes that any required macros inside will get before the if.
4367 * doc/autoconf.texi (autom4te.cache): A typo.
4369 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4371 Undo previous change, except keep the change to
4372 lib/autoconf/programs.m4 that replaced grep with shell
4373 pattern-matching. This is because net-snmp configure reads stdin.
4374 Reported by Noah Misch.
4376 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4378 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4379 from /dev/null, as "configure" shouldn't read stdin, and this
4380 insulates us from problems (e.g., when testing for "cl").
4381 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4382 before invoking "hostname" or "uname".
4383 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4384 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4385 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4386 "</dev/null" since it's now done at the top of 'configure'.
4387 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4388 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4389 Also, replace grep with shell pattern-matching, to save a process.
4391 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4393 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4394 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4395 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4396 compiler.
4398 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4400 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4401 grep -q isn't portable. Improve grep -s explanation.
4402 Problem reported by Dan Manthey.
4404 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4406 * doc/autoconf.texi (Special Shell Variables): Clarify
4407 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4409 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4411 * doc/autoconf.texi: Use @acronym for DJGPP.
4412 Fix some @code's that should have been @env's, and vice versa.
4413 Sort environment variable names.
4414 Mention that shells no longer inherit IFS.
4415 Don't recommend PATH_SEPARATOR=';' so strongly.
4416 Mention that $RANDOM might expand to the empty string.
4417 "symlink" and "soft link" -> "symbolic link".
4418 Improve mktemp description (reported by Bruno Haible).
4420 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
4422 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
4423 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
4424 Likewise.
4425 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
4426 Likewise.
4428 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
4430 * NEWS: Mention AT_COPYRIGHT.
4432 * tests/local.at (AT_CMP): Use diff directly on input files rather
4433 than copying them.
4435 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
4436 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
4438 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4439 and Paul Eggert <eggert@cs.ucla.edu>
4441 * tests/autotest.at (Empty test suite): New test.
4442 * tests/torture.at (Substitute and define special characters)
4443 (Substitute a 2000-byte string, Define to a 2000-byte string)
4444 (Substitute a newline, Define a newline): New tests.
4446 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4448 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
4449 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
4450 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
4451 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
4452 (Standard regular expressions): New test.
4453 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
4454 excess test name quoting.
4455 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
4456 CPPFLAGS to `configure' instead of setting it in `configure'.
4458 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
4459 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
4460 on some platforms.
4462 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
4463 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
4465 * tests/local.at (AT_CMP): New macro.
4466 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
4467 (AC_SAVE_STATE): Move environment grep...
4468 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
4469 (AT_CONFIG_CMP): New macro.
4470 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
4471 * tests/c.at (Extensions): Do not exit early.
4472 * tests/atlocal.in: Inherit $GREP.
4474 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
4475 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
4477 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
4478 (AC_COPYRIGHT): Factor header comment portion out and move into...
4479 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
4480 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
4481 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
4482 --version output.
4483 * tests/local.at: Add Autoconf test suite copyright notice.
4484 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
4486 2005-02-04 Bruno Haible <bruno@clisp.org>
4487 and Paul Eggert <eggert@cs.ucla.edu>
4489 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
4491 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
4493 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
4494 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4496 Try not to generated lines of unlimited length, as POSIX places a
4497 2047-byte limit on line length of portable text files.
4498 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
4499 Use newline as a separator, not space.
4500 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
4501 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
4502 space.
4504 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4506 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
4507 as_func_*. Add test to check whether positional parameters
4508 are restored after function return.
4510 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
4512 * doc/autoconf.texi (Special Shell Variables): Mention _,
4513 BIN_SH, DUALCASE. Say that variables other than "status" are safe
4514 if they contain a lower-case letter. The DUALCASE problem was
4515 reported by Ralf Wildenhues.
4517 * bin/autoconf.as: Don't exit with status 0 after write failure
4518 with --help or --version.
4519 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
4520 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
4522 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4524 * doc/autoconf.texi (Limitations of Usual Tools):
4525 Unicos 9 sed limitations.
4526 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
4527 to get the option-enhanced interface on older Crays. Try ftn for
4528 Fortran 95 (newer Crays).
4530 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
4532 * man/Makefile.am (.x.1): Go back to the simple solution, but take
4533 care to echo the commands, so the user knows what's going on.
4534 Modified from a suggestion by Stepan Kasal.
4536 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
4537 with a cross reference. Derived from a suggestion by Bruce Korb.

4557 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4558 Update the long comment explaining it.
4560 m4_require no longer writes an ``is required by'' line to the
4561 execution stack. It contains only one bit of non-redundant
4562 information: that the macro was required, not called. And even
4563 this bit is useless in most situations: have you ever met a macro
4564 which both calls and requires the same macro?
4566 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4567 (_m4_defun_pro_outer): ... only via this macro, for the outermost
4568 macro.
4569 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
4570 (m4_expansion_stack_pop): Remove the misplaced comment.
4571 (m4_require): Don't put the ``is required by'' line to the
4572 execution stack; slightly improve the out-of-a-defun error message.
4573 (_m4_divert_grow): New macro, counter for the temporary diversions.
4574 (_m4_require_call): Use it.
4575 * tests/m4sugar.at (m4_require): Expect output without the
4576 ``is required by'' messages.
4578 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4580 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4581 rather than x for expr.
4583 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
4584 this is safe.
4585 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
4586 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
4587 * lib/autotest/general.m4 (AT_INIT): Likewise.

4599 support.
4600 * bin/autoheader.in: Pass $force to update_file so that
4601 config.h.in is always recreated when --force.

4605 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
4607 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
4609 * doc/autoconf.texi (Limitations of Builtins): Clarify that

4612 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
4614 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
4615 Warn about newline stripping in `` and $(). Update Solaris
4616 version to 9.
4617 (Limitations of Builtins): Use expr "X...", not expr "x...", as
4618 X insulates us from future changes to Posix.
4619 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
4620 stripping.
4622 2005-01-19 Stepan Kasal <kasal@ucw.cz>
4624 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
4625 you cannot use AC_DEFINE to define macros containing `[' or `]'.

4641 reported by Michael Jennings via Daniel Reed; see
4642 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
4644 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
4646 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
4647 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
4648 datadir, infodir, and mandir. Adjust argument parsing code.

4668 (_m4_divert_n_stack): New macro; the expansion is
4669 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
4670 otherwise.
4671 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
4672 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
4673 stored in _m4_divert_diversion or _m4_divert_dump.
4674 (m4_divert_pop): When the parameter is given, compare the symbolic
4675 name with the last diversion pushed on the stack. Previously, the
4676 current diversion was compared with the numeric value of the
4677 diversion given as the parameter.
4678 (m4_require): If the macro hasn't been expanded yet, call ...
4679 (_m4_require_call): this new macro.

4712 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
4713 signals that the package uses Automake; a `Makefile.am' is typical but
4714 not essential. Reported by Magnus Therning.
4715 * tests/torture.at (autoreconf.): New banner.
4716 (autoreconf and non-AC configure): Rename to `Non-Autoconf
4717 AC_CONFIG_SUBDIRS'.

4765 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
4766 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

4893 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

4958 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
4960 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
4961 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
4962 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
4963 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
4965 2004-12-07 Stepan Kasal <kasal@ucw.cz>
4967 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

4978 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
4979 out the common code to ...
4980 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
4981 value of the #define--default to 1, iff the macro was called
4982 with exactly one parameter.
4984 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
4986 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4987 "char c = '\200';" rather than "char c = 0x80;" as the
4988 latter doesn't conform to the strict C standard due to
4989 overflow on signed char hosts.
4991 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
4992 to -qlanglvl=ansi. We don't want to disable extensions.
4994 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
4996 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
4997 (Using Autotest, testsuite Scripts, Writing testsuite.at):
4998 Reword slightly to avoid some English-language problems noted

5052 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
5053 the $1_found variable, don't test whether the file is executable;

5090 * doc/autoconf.texi (auindex): New macro.
5091 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
5092 Problem reported by Stepan Kasal.
5094 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
5096 Fix problems reported by Andreas Buening in:
5097 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
5098 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
5099 in test makefile.
5100 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
5101 readable; it's not true in OS/2-emx.
5103 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
5105 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5106 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5107 (trivial change). Problem and patch reported by Andrew Church in:
5108 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5110 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

5137 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5138 texinfo.tex for now (done by hand now).
5139 * Makefile.maint (wget_files, cvs_files):
5140 Remove ansi2knr.c; nobody uses it.
5141 (ansi2knr.c-url_prefix): Remove.
5142 (cvs-update): Fix test for failure. I don't know why it ever
5143 worked...
5145 * doc/autoconf.texi: Update URLs, some of which went stale.
5146 Use @uref rather than @href.
5148 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5149 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5151 * config/config.guess, config/config.sub, config/elisp-comp,
5152 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5153 doc/fdl.texi, doc/standards.texi: Sync with master copy.
5155 * NEWS, TODO, configure.ac, bin/autoscan.in,
5156 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
5157 doc/install.texi, lib/Autom4te/Configure_ac.pm,

5161 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
5162 tests/tools.at, tests/torture.at:
5163 Use "file name" rather than "filename" or "path",
5164 to be consistent with the terminology of the GNU coding standards.
5166 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5168 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5169 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5170 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5171 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5173 More fixes to support spaces in the name of the build directory.
5174 This isn't a complete fix but it's an improvement.
5176 * bin/autoconf.as (autom4te_options): New var.
5177 Use it instead of appending to AUTOM4TE, so that we can allow
5178 spaces in the build directory's absolute name.
5179 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5180 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
5181 AT_CHECK_NOESCAPE): Likewise.
5182 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
5183 main program): Likewise.
5185 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
5187 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

5191 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
5193 * doc/autoconf.texi (Function Portability): Document isinf and
5194 and isnan. From a suggestion by Kevin Ryde.
5196 * lib/Autom4te/General.pm (END): Return correct exit status even
5197 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5199 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5201 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5202 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5203 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5205 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5207 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5208 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5209 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5210 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5211 * lib/autom4te.in (Automake-preselections): Preselect
5212 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5214 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5216 * lib/autom4te.in (Automake-preselections): Preselect
5217 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5218 trace them.
5220 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5222 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5223 Tru64.
5224 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5225 Document problem with "`""`" in pdksh POSIX mode.
5227 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5229 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5230 with pdksh, too. Problem reported by Patrick Welche via
5231 Gary V. Vaughan.
5232 * doc/autoconf.texi (Shellology): Note that set -o posix is
5233 useful for pkdsh, too.
5235 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5237 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5238 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5239 Don't fail if ENV or BASH_ENV is readonly.
5240 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5241 etc. are read only. Problem reported by Ludovic Courtes.
5243 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5245 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5246 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5247 (trivial change)
5249 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5251 * doc/autoconf.texi (File System Conventions): Warn about
5252 names like "aux". Problem reported by Eric Blake.
5254 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5255 by zero instead of array size, so that we can use any arithmetic
5256 constant expression (instead of requiring an integer constant
5257 expression). This allows us to test expressions like DBL_MAX <
5258 LDBL_MAX, which didn't conform to the C standard using the old
5259 method.
5260 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5261 now that we can do floating-point tests at compile time.
5263 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5265 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5266 and LDBL_EPSILON, as the resulting expression isn't an
5267 integer constant expression and violates the C standard.
5268 Problem reported by Nelson H. F. Beebe. Also, check
5269 for "L" suffix, and check that long double doesn't have
5270 worse range or precision than double, that mixed-mode
5271 arithmetic doesn't generate a diagnostic, that double
5272 constants fit in long double.
5274 2004-06-03 Kevin Ryde <user42@zip.com.au>
5276 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5277 malloc(0) and realloc(NULL,size).
5279 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5280 Bob Proulx.
5282 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5284 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5285 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5286 by Jim Meyering.
5288 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5290 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5291 can be rewritten using if-then-else. Suggested by Bruno Haible.
5293 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5295 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5296 Problem reported by Stepan Kasal.
5298 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5300 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5301 change). Patch reported by Ralf Wildenhues in
5302 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5304 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5305 function F exists if the compiler and linker let you compile an
5306 expression like (F != 0). Recent versions of GCC optimize away
5307 the reference to F in that case, since every function address must
5308 be nonzero, so the link succeeds even if F does not exist.
5309 Problem reported by Manu in
5310 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5312 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5313 "Unix". Many uses changed.
5314 (Limitations of Builtins): Explain better why the ! command isn't
5315 portable.
5317 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5319 * lib/autom4te.in (Automake-preselections): Preselect
5320 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5322 2004-05-19 Kevin Ryde <user42@zip.com.au>
5324 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5325 referencing AC_FUNC_STRERROR_R.
5327 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5328 note pessimistic assumption when cross compiling.
5330 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5332 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5333 (until 2004) invoked subcommands with sh -e, contra POSIX.
5334 Reported by Kevin Ryde.
5336 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5338 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5339 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5340 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5341 `test -f " /usr/bin/grep"', which _always_ failed.
5342 (AC_PROG_SED): Ditto bogus PATH fix.
5343 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5344 requires that grep correctly supports _multiple_ `-e' options, rather
5345 than stating only that grep should accept `-e'.
5347 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5349 Port to C99, which requires that 'exit' be declared.
5351 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5352 to ensure that stdlib.h is included.
5353 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5354 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5355 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5356 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5357 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5358 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5359 when using 'exit' in a test; C99 requires that 'exit' be declared.
5361 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5363 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5364 now prefers 'grep' implementations that accept -e.
5365 (Limitations of Usual Tools): Describe problems of traditional
5366 egrep and fgrep with long input lines, and of traditional grep
5367 with -e.
5368 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5369 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5370 All callers changed. Append /usr/xpg4/bin to the PATH, for
5371 Solaris.
5372 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5373 the user with complaints about multiple -e options.
5374 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5375 Define it with AC_PROG_GREP.
5376 * configure.ac (AC_PROG_GREP): Add.
5377 * lib/freeze.mk (GREP): New macro.
5379 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5381 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5382 a possible candidate only after all others fail, rather than
5383 consulting it first. This improves backward compatibility by
5384 better reflecting the way shell selection occurred in previous
5385 versions of Autoconf, and should help to avoid triggering latent
5386 problems in other packages, such as the one in Automake where zsh
5387 is not handled robustly:
5388 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5389 Although it is not Autoconf's responsibility to work around
5390 problems in Automake, it nevertheless makes sense to avoid
5391 introducing unnecessary incompatibilites.
5393 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5394 Gary V. Vaughan <gary@gnu.org>
5396 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5397 how deeply nested we are when a suitable tool is found, set the
5398 ac_path_TOOL_found flag.
5399 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5400 nested we are in this macro. Break out of all 3 nested loops if
5401 ac_path_TOOL_found is set.
5403 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5405 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5406 of the _AS_PATH_WALK loop too if GNU flavor is found.
5408 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5410 * doc/autoconf.texi (Limitations of Make): Update documentation
5411 for `$<'. New entry `Long lines', based on a report from Simon
5412 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5413 paragraph about DJGPP, based on a mail from Richard Dawe.
5415 2004-04-20 Paul Eggert <eggert@twinsun.com>
5417 * tests/c.at (C keywords): Don't assume that GCC supports
5418 "restrict" and "inline", as sufficiently-old GCC versions do not
5419 (also, GCC configured to be in pedantic C89 mode does not).
5420 Problem reported by Sumit Pandya in:
5421 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5423 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5424 consider -g to work if it generates warnings when plain compiles
5425 don't. Problem reported by Braden McDaniel in:
5426 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5428 * doc/autoconf.texi (Slashes): New section, to document a problem
5429 reported by Jim Meyering in:
5430 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5432 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5433 linker output files before linking, to work around IRIX 6 linker bug.
5434 Problem reported by Rainer Orth in:
5435 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5437 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5439 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5440 best tool so far counter rely on the tool path variable name to
5441 avoid checks for one tool being affected by the results of running
5442 the length check on a previous tool.
5444 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5445 match expression argument, as different greps have different
5446 regular expression flavours.
5447 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5448 literals.
5449 (AC_PROG_EGREP): Pass 'EGREP$'.

5459 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
5460 Types, Specific Compiler Characteristics, System Services,
5461 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5462 etc. consistently instead of 'long', 'short', 'unsigned' etc.
5463 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
5464 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

5477 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
5478 now defines HAVE_DECL_TZNAME if it is declared, when
5479 HAVE_STRUCT_TM_TM_ZONE is not defined.
5480 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5481 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
5482 for HAVE_TZNAME.

5528 behavioral changes.
5529 * tests/mktests.sh: Do not generate tests for the
5530 new macros.
5531 * NEWS: Document these changes.
5533 * doc/autoconf.texi: Avoid macros with unbraced arguments,
5534 they make TeX hang up.

5539 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5540 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
5541 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
5542 vowel.

5562 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5564 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'

5567 2004-02-18 Paul Eggert <eggert@twinsun.com>
5569 Fix a dependencies problem, stemming from a Autoconf 2.59 build
5570 problem on QNX reported by Stephen Rasku in
5571 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
5573 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
5574 $(m4sh_m4f_dependencies); this removes a FIXME.
5575 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
5576 (MAINTAINERCLEANFILES): Split into pieces,
5577 one per related section. Add $(srcdir)/wrapper.in.

5582 AC_SUBST provides no portable way to escape literal newlines.
5584 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5585 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5586 Darwin uses -lcrt2.o and there's little point to cataloging all
5587 the system variants. Partial fix reported by Andreas Waechter in:
5588 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
5589 for bug reported by Nelson H. F. Beebe in:

5604 the behavior of the third argument.
5605 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
5606 correctly the behavior of the third argument. Document
5607 what the three macros that AU_DEFUN defines do. Fix
5608 warning message when the third argument includes $0

5611 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5612 Eric Sunshine <sunshine@sunshineco.com>
5613 Paul Eggert <eggert@twinsun.com>
5615 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

5617 parameter. Expand _AS_SHELL_FN_SPY.
5618 (AS_INIT_WITH_SHELL_FN): Removed.
5619 (_AS_SHELL_FN_SPY): New macro.
5620 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
5621 macros.
5622 (AS_SHELL_SANITIZE): Remove loop to find better shell
5623 and documentation for the parameter.
5624 (_AS_DETECT_BETTER_SHELL): Move it here.

5627 (AS_REQUIRE_SHELL_FN): Require shell functions when
5628 it is used.
5629 (_AS_LINENO_WORKS): Put around braces, we do not
5630 trigger the bash bug anymore.
5631 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
5632 use AS_INIT_WITH_SHELL_FN.
5633 * bin/autoconf.in, tests/wrapper.in: Regenerated.
5635 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5637 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

5639 is broken.
5640 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
5641 (AU_DEFUN): Honor the third parameter, create autoupdate
5642 macros with AU_DEFINE.
5643 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
5644 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

5663 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
5664 2003 (except 1997) to the list of copyright years. This undoes
5665 the 2003-05-22 change, which removed the older years from the list.
5666 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
5668 2004-01-27 Gary V. Vaughan <gary@gnu.org>
5669 Albert Chin-A-Young <china@thewrittenword.com>

5680 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
5681 longest input length accepted by a command.
5682 (AC_PROG_SED): Use it.
5683 * doc/autoconf.texi (Particular Programs): Document the changes.
5684 * NEWS: Updated.
5686 2004-01-27 Paul Eggert <eggert@twinsun.com>

5708 sources.
5710 2004-01-26 Paul Eggert <eggert@twinsun.com>
5712 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
5713 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
5714 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
5715 not <inttypes.h>. Problem reported by Tim Mooney in
5716 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
5717 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
5718 Likewise.
5720 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
5721 otherwise "make check" fails because it forbids cmp (I guess
5722 because cmp treats files as binary on DOS-like systems).
5724 * tests/mktests.sh: Update copyright date to 2004, since some tests
5725 have changed in 2004.
5727 2004-01-23 Gary V. Vaughan <gary@gnu.org>

5730 non-truncating sed or gsed program in PATH.
5731 * tests/acprograms.at: Add it.
5732 * doc/autoconf.texi (Particular Programs): Document it.
5733 * NEWS: Updated.
5735 2004-01-15 Paul Eggert <eggert@twinsun.com>
5737 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
5738 -std1 disables some useful extensions on Tru64. Problem reported
5739 by N. Lichtmaier in
5740 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
5742 2004-01-14 Paul Eggert <eggert@twinsun.com>
5744 * doc/autoconf.texi (Programming in M4sh): Document that
5745 AS_MKDIR_P succeeds if the destination is a symbolic link
5746 to an existing directory.
5747 (Limitations of Usual Tools): Note that mkdir -p might not
5748 succeed on symlinks to directories.
5750 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
5752 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
5753 * bin/autoheader.in: Grammar fix in message.
5754 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
5755 Test for dir before calling mkdir -p. (trivial changes)
5757 2004-01-13 Eric Blake <ebb9@byu.net>
5759 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
5760 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
5762 2004-01-10 Jim Meyering <jim@meyering.net>
5764 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
5766 2004-01-09 Paul Eggert <eggert@twinsun.com>
5768 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
5769 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
5770 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
5771 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
5772 AC_COMPILE_IFELSE, since we now assume our caller invokes
5773 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
5774 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
5775 of AC_RUN_IFELSE; this avoids the warning mentioned above.
5776 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
5778 2004-01-07 Paul Eggert <eggert@twinsun.com>
5780 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
5781 `"'...'"`, as it's confusing (and I suspect it may not work on
5782 some platforms). The code was incorrect anyway, as it assumed
5783 that \$ evaluated to itself in that context. Reported by
5784 Alexandre Duret-Lutz.
5786 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
5788 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
5789 and _LT_AC_TAGCONFIG.
5791 2004-01-06 Paul Eggert <eggert@twinsun.com>
5793 * doc/autoconf.texi (One Macro Call): Fix an incorrect
5794 example, and add more examples. Reported by Eric Sunshine.
5796 2004-01-05 Paul Eggert <eggert@twinsun.com>
5798 * doc/autoconf.texi (Limitations of Usual Tools):
5799 Remove warning against "rm -fr" introduced yesterday; it
5800 was a false alarm.
5802 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
5803 autoscan, autoupdate, ifnames): Don't use chmod -w.
5804 * lib/Makefile.am (autom4te.cfg): Likewise.
5805 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
5806 "chmod -w".
5808 2004-01-04 Paul Eggert <eggert@twinsun.com>
5809 Paolo Bonzini <bonzini@gnu.org>
5811 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
5812 by doing lineno substitution only on lines containing "$LINENO".
5814 2004-01-04 Paul Eggert <eggert@twinsun.com>
5816 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
5817 Use "rm -f" to remove conftest.sed, not plain "rm".
5818 Bug reported by David Relson in
5819 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
5821 * Makefile.am (autom4te-update):
5822 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
5823 * Makefile.maint (my-distcheck, do-po-update): Likewise.
5824 * doc/autoconf.texi (Guidelines): Likewise.
5825 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

5831 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
5832 srcdir): Likewise.
5833 * doc/autoconf.texi (Limitations of Usual Tools):
5834 Warn against "rm -fr".
5836 2004-01-03 Paul Eggert <eggert@twinsun.com>
5838 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
5839 -c -o might not work. From a suggestion by Kevin Ryde.
5840 (C Compiler, Generating Sources, Limitations
5841 of Usual Tools, Limitations of Make, Making testsuite Scripts):
5842 Don't put '-o' after non-options, as POSIX doesn't allow this.
5843 Mention that cc's name might be gcc or c89 or whatever.
5845 2004-01-04 Kevin Ryde <user42@zip.com.au>
5847 * doc/autoconf.texi: Add various further index entries.
5849 2003-12-29 Paul Eggert <eggert@twinsun.com>
5851 * bin/autoreconf.in (autoreconf_current_directory):
5852 Fix typo: mkdir without umask arg.
5854 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
5856 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
5857 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
5858 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
5859 explanation clearer.
5861 2003-12-24 Andreas Schwab <schwab@suse.de>
5863 * doc/autoconf.texi (Default Includes): Fix misspelling of
5864 AC_INCLUDES_DEFAULT.
5866 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
5868 * configure.ac: Test if sh -n works.
5869 * configure: Regenerate.
5870 * tests/atlocal.in: Store the result here.
5871 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
5872 tools.at, looking in atlocal's ac_cv_sh_n_works instead
5873 of explicitly testing.
5874 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
5875 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
5876 * tests/tools.at (Syntax of the shell scripts): Simplify
5877 using AT_CHECK_SHELL_SYNTAX.

5910 * config/announce-gen (&print_locations, &print_signatures)
5911 (&sizes): New.
5912 Use them.

5914 them on the fly.
5916 2003-11-24 Akim Demaille <akim@epita.fr>
5918 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6122 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
6123 cross test.
6125 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
6127 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
6128 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

6140 Problems reported by Eric Sunshine.
6142 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6144 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6145 -mGLOB_options_string stuff for Intel ifc, which can cause

6169 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6170 cache variable instead of $G77 to decide whether to include -O2,
6171 since $G77 is specific to Fortran 77.

6175 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

6180 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6181 arguments so that it can be used with syntax identical to
6182 AC_PROG_F77, and so that we can more easily decide to
6183 remove/deprecate the DIALECT optional argument in the future if it
6184 proves troublesome.
6185 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
6186 non-freeform-supporting compilers. Document freeform flags.
6188 2003-10-03 Akim Demaille <akim@epita.fr>
6190 * configure.ac: Look for emacs, not macs.
6191 Reported by Eric Sunshine.
6193 2003-10-03 Akim Demaille <akim@epita.fr>
6195 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
6196 * bin/autoreconf.in (autoreconf_current_directory): Create the

6198 Suggested by Alexandre Duret-Lutz.
6200 2003-10-03 Akim Demaille <akim@epita.fr>
6202 * configure.ac: Quotation and formatting changes.

6225 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.

6237 have been created when invoking the compiler.

6251 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6252 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6253 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6255 2003-09-26 Akim Demaille <akim@epita.fr>
6257 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6258 directory for AC_CONFIG_COMMANDS' first argument exists.
6259 This makes valid the invocation of _AC_SRCPATH that follows.
6260 Reported by Eric Sunshine.
6261 * doc/autoconf.texi (Configuration Commands): Adjust.
6263 2003-09-26 Akim Demaille <akim@epita.fr>
6265 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6266 Reported by Ralf Corsepius.

6270 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6271 arguments.

6282 2003-09-26 Akim Demaille <akim@epita.fr>
6284 The test suite are sometimes assigning timings incorrectly.
6285 Reported by Henk Krus.
6286 Diagnosed by Nicolas Joly.
6288 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6289 AT_help_all.
6290 Instead of making AT_help a sequence of assignments to grow
6291 $at_help_all, just make AT_help_all be the growing contents of
6292 $at_help_all, and make a single assignment in...
6293 (AT_INIT): here.
6294 (at_times_skip): Flip the meaning and rename as...
6295 (at_times_p): this.
6296 (AT_INIT): When summarizing the test that ran, remove
6297 $at_times_file after use, and check it is present before trying to
6298 use it.

6306 (ifnames): chmod -w.
6307 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6308 executables, not bin/ executables! Otherwise all the magic needed
6309 to find non installed files is turned off. This caused a failure
6310 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6311 as found in its environment (sent by tests/autoreconf): pointing
6312 to bin/autom4te that could not find its files.
6313 * tests/mktests.sh: Force the replacement of generated files, for
6314 the sake of "mv" program that are interactive when overwriting a
6315 -w file.

6326 Trivial change to support GCC's configuration procedure.
6327 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6328 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6329 about inconsistency if the preprocessor is set to give errors for
6330 any warning.
6331 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6333 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

6349 2003-09-12 Akim Demaille <akim@epita.fr>
6351 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
6352 not asm/types.h.
6354 2003-09-11 Akim Demaille <akim@epita.fr>
6356 * doc/autoconf.texi (Header Portability): linux/random.h.
6357 From Peter Hendrickson.
6359 2003-09-10 Akim Demaille <akim@epita.fr>
6361 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6362 willing to edit the output files.
6364 2003-09-10 Akim Demaille <akim@epita.fr>
6366 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6367 and AC_FC_FREEFORM.
6368 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6369 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

6391 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6392 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6394 2003-09-04 Akim Demaille <akim@epita.fr>
6396 * tests/mktests.sh (ac_exclude_list): Fix the filtering of

6412 unchanged, and continues to support Fortran 77. New FC macros
6413 correspond to all the old F77 macros, with output variables FC,
6414 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6415 available dialect, but older dialects can be specified. There are
6416 new macros AC_FC_SRCEXT to set the source extension, and
6417 AC_FC_FREEFORM to accept free-form source files.

6450 2003-08-27 Akim Demaille <akim@epita.fr>
6452 * tests/m4sugar.at (cross_warning): Make sure to enable the
6453 output, so that we can track spurious m4sugar output.

6455 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
6456 are defaulted by AT_CHECK anyway.

6543 2003-08-21 Akim Demaille <akim@epita.fr>
6545 First stab at preserving warnings between calls to autom4te,
6546 including when the cache is used.
6548 There are still several issues: (i) there are too many runs of m4
6549 (one for include, one for warnings, and some more), (ii) warnings
6550 spreading on several lines are not handled gracefully, (iii) the
6551 code meant to have the call stack display for errors does not work
6552 (its handling should move from m4 to autom4te).
6554 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6555 Use them.
6556 (@preselect): Add m4_warn.
6557 ($exit_status): Remove, use $exit_code.
6558 ($help): Use Autom4te::ChannelDefs::usage.
6559 (&handle_m4): No longer define the m4_warnings.
6560 At each run, extract and report the warnings.
6561 Always cache the result, including if the exit status is on
6562 failure, since if nothing changes, we should result in the same
6563 failure, hence we can use the cache.
6564 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6565 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6566 Remove.
6567 (m4_warn): Redefine as a do-nothing: it is its invocation that
6568 matters, as warnings are now reported via traces.
6569 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6570 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6571 the latter reveals calls to the former.
6573 Adjust the tests.
6575 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6577 2003-08-21 Akim Demaille <akim@epita.fr>
6579 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
6580 Use them.
6582 2003-08-21 Akim Demaille <akim@epita.fr>
6584 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
6585 forward order.
6586 * lib/Autom4te/ChannelDefs.pm: Doc typos.
6587 (&parse_warnings): Accept a list of warning requests.
6588 (&usage): Return a string, not a side effect.
6589 (cross): New warning category.
6591 2003-08-21 Akim Demaille <akim@epita.fr>
6593 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
6594 (&require_configure_ac): Accept an optional directory argument.
6595 ($configure_ac): Remove.
6596 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
6597 (&catfile): Remove.
6598 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
6599 * bin/autoscan.in: Adjust.
6601 2003-08-20 Akim Demaille <akim@epita.fr>
6603 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
6604 Reported by Alexandre Duret-Lutz.
6606 2003-08-20 Akim Demaille <akim@epita.fr>
6608 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
6609 * bin/autom4te: Adjust.
6610 In particular, be Autoconf tools are really silent when properly
6611 working, bind the verbosity of the 'note' channel to $verbose.
6612 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
6613 (&xsystem, &contents): Remove, since they are exported by...
6614 * lib/Autom4te/FileUtils.pm: this.
6615 More perldoc.
6616 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
6617 * lib/Autom4te/FileUtils.pm: here.
6619 2003-08-20 Akim Demaille <akim@epita.fr>
6621 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
6622 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

6675 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
6676 shorter column three. Add DESCRIPTION to log file content.
6678 2003-08-13 Derek Price <derek@ximbiot.com>
6680 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
6681 output.

6694 2003-07-31 Paul Eggert <eggert@twinsun.com>
6696 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
6697 in Bash 2.01. Problem reported by Brian Gough in
6698 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

6709 Bob Friesenhahn.
6711 2003-07-06 Bill Clarke <llib@computer.org>
6713 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
6714 'long', not 'int', for benefit of Sun's recent C++ compilers
6715 (trivial change). See:
6716 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
6717 (This really should be 'intptr_t', not 'long', but that would
6718 take more work.)
6720 2003-06-25 Akim Demaille <akim@epita.fr>

6736 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
6737 not all of them. This fixes 1. the fact that when testing
6738 Autoconf there are many many config.log, 2. the incorrect use of
6739 top_srcdir to find config.log.
6740 Don't mix the detailed output of failed test with the summary of
6741 failures. Rather, append detailed log afterwards.
6743 2003-06-23 Akim Demaille <akim@epita.fr>
6745 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

6828 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
6830 * lib/Autom4te/General.pm (END): Rewrite exit code processing.

6853 * Makefile.am, bin/Makefile.am, config/Makefile.am,
6854 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
6855 White spaces cleanup.
6857 2003-05-22 Jim Meyering <jim@meyering.net>
6858 Paul Eggert <eggert@twinsun.com>
6860 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6861 Remove `#include <stdlib.h>' from the list; we should never
6862 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6863 resulting namespace pollution would cause other tests to fail.
6864 Configure scripts run with some older versions of g++ and HP's
6865 aCC would fail due to such an #include. Problems reported by
6866 Matthew Mueller in <http://bugs.debian.org/120704> and by
6867 Keith Bostic in
6868 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6869 In the test, use the test declaration before including <stdlib.h>,
6870 as that's closer to how it'll be used.
6872 2003-05-23 Akim Demaille <akim@epita.fr>
6874 * doc/autoconf.texi (Header Portability): ucred.h.
6875 From Ian Redfern.
6877 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6879 Overhaul Autotest's logging: generate separate log files
6880 in testsuite.dir/NNN/testsuite.log, and append them to
6881 testsuite.log instead of re-running the test verbosely.
6883 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6884 file descriptor, write 0 to at_status_file instead of setting
6885 at_status=0, initialize some new variables (at_status_file,
6886 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6887 to rerun the tests, instead append the at_group_log to the
6888 at_suite_log when a test fails.
6889 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6890 with the AS_MESSAGE_LOG_FD redirected to stdout.
6891 (AT_CLEANUP): save the output status in $at_status_file
6892 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6893 its original place.
6894 (AT_CHECK): since tests are run with a redirected stdout,
6895 and used to be re-run in verbose mode, turn some $at_verbose
6896 into echo, and don't redirect the output of testing stdout
6897 and stderr.
6899 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6900 the name of the debugging directory and information about
6901 its contents.
6903 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6905 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
6906 parameter.

7018 and truncate.
7020 2003-05-06 Akim Demaille <akim@epita.fr>
7022 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7023 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7024 by aclocal.m4 is changed it might require the importing of another
7025 m4 extension file, i.e., aclocal must be run.
7027 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7028 (&parse_args): Use --force with aclocal if required and supported.
7029 (&autoreconf_current_directory): Use &run_aclocal.

7036 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7037 argument instead of a file name, so that the request file remains
7038 open during the whole autom4te run.
7039 ($icache_file): New.
7040 (&freeze): Lock the $icache_file.
7042 2003-04-29 Derek Price <derek@ximbiot.com>
7044 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7045 seperator with m4_append_uniq(). It doesn't work.
7046 (AT_CLEANUP): Add `;' to end of at_help_all.
7047 (AT_INIT): Allow --keywords to be specified more than once. When
7048 grepping $at_help_all for keywords, use the field and keyword
7049 seperators to ensure a complete keyword match. Alter at_prev handling
7050 to support the new --keywords behavior.
7052 2003-04-27 Karl Berry <karl@freefriends.org>
7054 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7055 align better with others. I also made some of the individual
7056 entries on one line, for brevity and to make it easier for me to
7057 sort my dir-example file in the Texinfo distribution :).
7059 2003-04-12 Jim Meyering <jim@meyering.net>

7124 header causes problems.
7126 2003-03-28 Akim Demaille <akim@epita.fr>
7128 * tests/torture.at (Configuring subdirectories): Require aclocal
7129 1.4, otherwise the test fails, as it does support configure.ac.

7202 Tru64 make in the "target lookup" section.
7203 (Automake): Automake 1.5+ no longer requires special tools to be

7225 When constructing paths with IFS=:, quote the path. If we're

7249 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
7250 format starting with "-".
7252 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7254 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
7255 is not portable inside Makefile.
7257 2003-02-20 Akim Demaille <akim@epita.fr>
7259 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7260 compiler says yeah, but preproc says nope, compiler is right.
7261 Conversely, prompt the reader to send a bug report to the
7262 maintainers of the package, not of Autoconf.
7264 2003-02-20 Klee Dienes <kdienes@apple.com>
7266 * bin/autoreconf.in (autoreconf_current_directory): Properly

7277 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7278 innocuous variant befor including <limits.h> or <assert.h>. This
7279 works around a bug reported by Albert Chin: HP-UX 11i
7280 (and earlier versions) have a <limits.h> that declares
7281 gettimeofday and many other functions.
7283 2002-12-03 Paul Eggert <eggert@twinsun.com>
7285 Version 2.57.
7287 * NEWS, configure.ac: Update version.

7291 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7292 nontrivially in main's body, so that f's external declaration is
7293 not optimized away in AIX. This should fix the bug reported by
7294 Martin Frydl in
7295 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7297 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7298 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7299 defined, to support freestanding compilers. This should fix the
7300 bug reported by Momchil Velkov in
7301 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7303 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7304 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
7305 obsolete AC_CHECK_TYPE. The missing empty arg was reported
7306 by Simon Josefsson in

7309 * Makefile.maint (www-gnu): New macro.
7310 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
7311 the location has moved.
7313 2002-12-02 Martin Frydl <martin@systinet.com>
7315 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
7316 \(.*\) match is too long and there is something more to be checked.
7317 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

7339 * Makefile.maint: Sync with Bison, i.e.:
7340 (po-check): Scan .l and .y files instead of the
7341 .c and the .h files that they generate. This fixes the bug
7342 reported by Tim Van Holder in:
7343 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7344 Look for N_ as well as for _. Try to avoid matching #define for
7345 N_ and _.
7346 From Paul Eggert.
7348 2002-11-14 Akim Demaille <akim@epita.fr>
7350 * doc/autoconf.texi (C Compiler): Compiling several files at once.
7351 From Paul Eggert and Albert Chin-A-Young.
7353 2002-11-14 Akim Demaille <akim@epita.fr>
7355 * doc/autoconf.texi (C Compiler): Solitary backslashes.
7356 From Paul Eggert and Albert Chin-A-Young.
7358 2002-11-14 Kevin Ryde <user42@zip.com.au>
7360 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
7361 than assigning in main, to avoid HP cc +O3 optimizing it away.
7363 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
7365 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
7366 option. Process --recheck after parsing all options. Pass -q
7367 option to configure on --recheck.
7368 (AC_OUTPUT): Pass -q from configure to config.status.
7369 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
7370 arguments to record.
7371 * doc/autoconf.texi (config.status Invocation): Document
7372 config.status -q option.
7374 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
7376 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
7377 Makefile.in if Makefile.am exists.

7399 Reported by Ezra Peisach.
7401 2002-11-05 Akim Demaille <akim@epita.fr>
7403 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7404 Remove.
7405 We _have_ to stop using the old compatibility scheme that tried to
7406 avoid useless backslashes because Libtool 1.4.3 contains a
7407 AC_DEFINE([error_t], [int],
7408 [Define to a type to use for \`error_t' if it is not
7409 otherwise available.])
7410 We _have_ to quote the single quote and backslashes with \. The
7411 old compatibility scheme saw that ` was backslashed, and therefore
7412 did not quote the single quote. Hence before this patch, Autoconf
7413 was not compatible with Libtool.
7415 2002-11-04 Paul Eggert <eggert@twinsun.com>
7417 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

7457 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
7458 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
7459 Make variable, not a shell variable.
7460 Suggested by Bruno Haible.
7462 2002-10-31 Akim Demaille <akim@epita.fr>
7464 * bin/autom4te.in (load_configuration): Reject #args out of any
7465 language.

7481 Suggested by Tim van Holder.

7486 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
7487 Problem reported by Bruno Haible.
7489 2002-10-29 Akim Demaille <akim@epita.fr>
7491 * doc/autoconf.texi (Header Templates): Put also in words what the

7495 2002-10-29 Akim Demaille <akim@epita.fr>

7745 2002-10-22 Akim Demaille <akim@epita.fr>

7803 longer required can still cause errors.
7804 Reported by Alexandre Duret-Lutz.
7806 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

7827 if some file was changed instead of `print'.
7828 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
7829 (&parse_args): Remove the dead options.
7830 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
7831 autoheader's quiet mode.
7832 (AT_CHECK_AUTOUPDATE): Likewise.
7833 * tests/tools.at (autoupdate): Adjust.
7834 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7836 2002-10-11 Akim Demaille <akim@epita.fr>
7838 No longer use CPP to check for the existing of headers: use CC to
7839 check for compilability.
7841 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
7842 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
7843 (_AC_CHECK_HEADER_NEW): Rename as...
7844 (AC_CHECK_HEADER): this.
7846 * lib/autotest/general.m4 (AT_INIT): Include the failed test
7847 numbers in the Subject suggestion.
7849 2002-10-11 Akim Demaille <akim@epita.fr>
7851 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
7852 Suggest using AC_CHECK_DECLS instead.
7854 2002-10-11 Akim Demaille <akim@epita.fr>
7856 * tests/torture.at (AC_ARG_VAR): Have configure report the value
7857 of `precious'.
7859 2002-10-11 Akim Demaille <akim@epita.fr>
7861 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
7862 file name to enable parallel executions.
7863 From Sam Varshavchik.
7865 2002-10-08 Akim Demaille <akim@epita.fr>
7867 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7868 aclocal invocation, as Gettext macros might not be visible to
7869 aclocal.
7870 Instead of blindly running autopoint, scan configure.ac (not the
7871 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
7872 Reported by Paul D. Smith.
7874 2002-10-08 Paul Eggert <eggert@twinsun.com>
7876 Work around problems found when POSIXLY_CORRECT=1 is set.
7877 None of this seems to have anything to do with POSIX, really,
7878 but it's how Perl getopt works.
7879 * bin/autom4te.in (parse_args): Configure GetOpt with
7880 "permute", too.
7881 * doc/autoconf.texi (Invoking autom4te):
7882 --warning -> --warnings.
7883 * lib/autom4te.in: --warning -> --warnings.
7885 2002-09-28 Akim Demaille <akim@epita.fr>
7887 * doc/autoconf.texi (autom4te.cache): New section.
7889 2002-09-28 Akim Demaille <akim@epita.fr>
7891 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
7892 (Automake-preselections): Update.
7893 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
7895 2002-09-28 Akim Demaille <akim@epita.fr>
7897 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
7898 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
7899 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
7900 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
7902 2002-09-28 Akim Demaille <akim@epita.fr>
7904 * tests/torture.at (Configuring subdirectories): Be robust to
7905 users who use config.site to require for a cache: in this case,
7906 the two last configure runs, using two different sets of
7907 arguments, trigger a legitimate error.
7909 2002-09-28 Akim Demaille <akim@epita.fr>
7911 * tests/m4sh.at (Functions Support, Functions and return Support):
7912 New.
7914 2002-09-28 Akim Demaille <akim@epita.fr>
7916 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
7917 autoheader are Perl programs.
7918 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
7919 (autom4te): Specify that the sources are in the $srcdir.
7920 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7922 2002-09-28 Akim Demaille <akim@epita.fr>
7924 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
7925 (tm_zone): Move their rules to...
7926 * lib/autoconf/types.m4: here, using AN_ macros.
7927 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
7928 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7929 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
7930 * lib/autoconf/programs.m4: here.
7931 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
7932 (ETAGS_FOR_AUTOCONF): New.
7933 Use it.
7935 2002-09-28 Akim Demaille <akim@epita.fr>
7937 * lib/autoconf/autoscan.m4: New file.
7938 * lib/autoconf/autoconf.m4: Include it.
7939 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
7940 that were listed in the original autoscan.list.
7941 * lib/autoconf/headers.m4: Similarly with headers.
7942 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
7943 (.m4.m4f): Don't pass --prepend-include, since that's done by
7944 tests/autom4te itself.
7945 * lib/autoscan/Makefile.am: Include freeze.mk.
7946 (autoscan.list): New target --this file is no longer a source.
7947 (autoscan.pre): New file.
7949 2002-09-28 Akim Demaille <akim@epita.fr>
7951 * bin/autoscan.in (@kinds): Make them singular.
7952 Adjust all uses.
7953 (&init_tables): When --debug, report the list of rules to ease
7954 tracking changes in autoscan.list.
7955 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7957 2002-09-28 Akim Demaille <akim@epita.fr>
7959 * lib/autoscan/functions, lib/autoscan/headers,
7960 * lib/autoscan/identifiers, lib/autoscan/makevars,
7961 * lib/autoscan/programs: Merge into...
7962 * lib/autoscan/autoscan.list: this.
7963 * bin/autoscan.in (&init_tables): Adjust.
7965 2002-09-28 Akim Demaille <akim@epita.fr>
7967 * lib/autoscan/functions, lib/autoscan/headers,
7968 * lib/autoscan/identifiers, lib/autoscan/makevars,
7969 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
7970 `functions' line is now prefixed with `function:'.
7971 * bin/autoscan.in (&init_tables): Adjust.
7973 2002-09-28 Akim Demaille <akim@epita.fr>
7975 From now on, autoscan files must always map a macro name to a
7976 word: there is no `default' macro for autoscan.
7978 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7979 all.
7980 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7981 explicit.
7983 2002-09-28 Akim Demaille <akim@epita.fr>
7985 * bin/autoscan.in (%c_keywords): Remove.
7986 (&used): Keep only track of the words we might be interested in.
7987 (&output_kind): It is no longer needed to look for non active
7988 checks.
7990 2002-09-27 Akim Demaille <akim@epita.fr>
7992 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
7993 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
7994 * lib/autoscan/functions: Adjust.
7995 * doc/autoconf.texi (Particular Functions): Adjust.
7997 2002-09-27 Akim Demaille <akim@epita.fr>
7999 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
8000 from /tmp.
8001 Thanks to Bill Moseley and Paul Eggert.
8002 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8003 the tmpdir must be created.
8004 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8005 dir be in the build tree, instead of $TMPDIR.
8007 2002-09-27 Akim Demaille <akim@epita.fr>
8009 * bin/autoscan.in: Improve the comments.
8010 (&parse_args): Drop obsolete undocumented options.
8011 (&output_kind): Output warnings.
8012 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
8013 (getwd): Trigger a warning.
8015 2002-09-26 Akim Demaille <akim@epita.fr>
8017 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
8018 Reported by Ralf Corsepius.
8019 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8021 2002-09-26 Akim Demaille <akim@epita.fr>
8023 Single suffix rules and seperated dependencies are not portable.
8025 * doc/autoconf.texi (Installation Directory Variables): Update.
8026 (Limitations of Make): Some about `Single Suffix Rules and
8027 Separated Dependencies'.
8028 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8029 (ifnames, autoscan, autom4te): Un-factor into several rules.
8031 2002-09-25 Paul Eggert <eggert@twinsun.com>
8033 * BUGS (Interoperability bugs): New section. Mention libtool
8034 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8036 2002-09-24 Paul Eggert <eggert@twinsun.com>
8038 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8039 make handles suffix-rules differently from GNU make.
8041 * bin/Makefile.am (SUFFIXES, .in): Remove.
8042 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8043 Move the body of the old .in rule here.
8045 2002-09-16 Akim Demaille <akim@epita.fr>
8047 i960 compilers create `b.out' files by default.
8048 Reported by Ralf Corsepius.
8050 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8051 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8053 2002-09-13 Paul Eggert <eggert@twinsun.com>
8055 * doc/autoconf.texi (Particular Headers): Remove obsolete
8056 reference to `struct timezone' in the description of
8057 AC_HEADER_TIME.
8059 2002-09-13 Akim Demaille <akim@epita.fr>
8061 Version 2.54.
8063 * config/config.sub, config/config.guess: Update.
8064 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8065 * Makefile.am: Adjust.
8067 2002-09-13 Akim Demaille <akim@epita.fr>
8069 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8070 reading config.log when the compiler is rejected.
8071 Suggested by Guido Draheim.
8073 2002-09-13 Akim Demaille <akim@epita.fr>
8075 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8076 (chdir_init) might hang when stat'ing mounted directories.
8077 Reported by Vance Shipley.
8079 2002-09-12 Akim Demaille <akim@epita.fr>
8081 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8082 the lists.
8084 2002-09-12 Akim Demaille <akim@epita.fr>
8086 * doc/autoconf.texi (Defining Symbols): Present two different
8087 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8088 difference between 1 argument calls, and 2-3 argument calls.
8090 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8092 * doc/autoconf.texi: Review grammar and punctuation.
8094 2002-09-11 Paul Eggert <eggert@twinsun.com>
8096 * doc/autoconf.texi: Fix minor formatting, spelling, and
8097 grammatical typos.
8098 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8099 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8100 is obsolescent.
8102 2002-09-11 Akim Demaille <akim@epita.fr>
8104 * doc/autoconf.texi (Questions): Rename as...
8105 (FAQ): this.
8106 (Defining Directories): New.
8108 2002-09-09 Akim Demaille <akim@epita.fr>
8110 * doc/autoconf.texi (Making testsuite Scripts): Update.
8111 Suggested by Nishio Futoshi.
8113 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8115 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8116 plain `@' is wanted.
8118 2002-09-09 Akim Demaille <akim@epita.fr>
8120 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8121 `duplicates', since the algorithm was too naive and could keep
8122 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8123 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8124 Reported by Ralf Corsepius.
8125 * tests/torture.at (Configuring subdirectories): Exercise these
8126 cases.
8128 2002-09-09 Akim Demaille <akim@epita.fr>
8130 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8131 looking for a replacement file.
8132 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8133 directory is relative.
8134 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8135 directory definition.
8136 Reported by Andreas Schwab and Jim Meyering.
8138 2002-09-06 Akim Demaille <akim@epita.fr>
8140 * doc/autoconf.texi (Setting Output Variables): Clarify what
8141 precious variables are.
8142 Suggested by Pontus Skoeld.
8144 2002-09-05 Akim Demaille <akim@epita.fr>
8146 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8147 (ifnames, autoscan, autom4te): Since we don't only depend on
8148 configure.ac variables (such as VERSION etc.), but also on prefix
8149 and so forth, depend on Makefile, not configure.ac.
8150 Reported by Alexandre Duret-Lutz.
8151 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8153 2002-09-05 Kevin Ryde <user42@zip.com.au>
8155 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8156 doesn't seem to be confined to ia64, just say "some versions".
8158 2002-09-04 Akim Demaille <akim@epita.fr>
8160 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8161 Automake 1.6c.
8162 * Makefile.am (maintainer-clean-local): Remove.
8163 (MAINTAINERCLEANFILES): Remove COPYING.
8165 2002-09-03 Paul Eggert <eggert@twinsun.com>
8167 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8168 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8169 Brinkmann.
8171 2002-09-03 Akim Demaille <akim@epita.fr>
8173 * configure.ac: Bump to 2.53d.
8174 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8175 as of today, on Automake's team suggestion.
8177 2002-09-03 Akim Demaille <akim@epita.fr>
8179 Version 2.53c.
8181 2002-09-02 Akim Demaille <akim@epita.fr>
8183 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8184 SITE_MACRO_DIR.
8185 * configure.ac: Disable SITE_MACRO_DIR.
8187 2002-09-02 Jim Meyering <meyering@lucent.com>
8189 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8190 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8191 Also, tweak grammar: s/make sure to/be sure to/.
8193 2002-09-02 Paul Eggert <eggert@twinsun.com>
8195 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8196 directory names are generally preferable to physical names.
8198 2002-09-02 Akim Demaille <akim@epita.fr>
8200 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8201 Reported by Raja R. Harinath.
8202 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8203 * bin/autoupdate.in: Use error instead of die.
8205 2002-09-01 Paul Eggert <eggert@twinsun.com>
8207 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8208 ordinary shell concatenation rather than echo+tr+sed command that
8209 runs afoul of a long-line-related sed bug in Solaris 8.
8211 * bin/autoheader.in (parse_args): --warning -> --warnings.
8213 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8214 stdout, as traditional "ls" does.
8215 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8216 _AC_COMPILER_EXEEXT_O): Likewise.
8217 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8219 * bin/autoconf.as: Add --prepend-include option. This patch was
8220 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8221 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8223 * bin/autoconf.in, configure: Regenerate.
8225 * doc/autoconf.texi (Special Shell Variables): Mention
8226 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8228 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8229 MAILPATH and set PS1, PS2, PS4 to default values, to work
8230 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8231 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8232 the Autoconf documentation specifies; fall back to "unset" only if
8233 this fails. Use a shell for-loop for this rather than an m4 loop,
8234 to shorten the output script.
8236 2002-08-30 Paul Eggert <eggert@twinsun.com>
8238 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8239 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8240 for the CDPATH problem. Document PWD.
8241 (Limitations of Builtins): Document the problem that "cd $foo" and
8242 "ls $foo" may refer to different directories in shells conforming
8243 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8244 example, since the old example is now out of date.
8246 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8247 FOO" and "ls FOO" talk about different directories; this catches
8248 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8249 spaghetti.
8251 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8252 of rolling our own unset.
8253 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8254 in practice we needn't worry about CDPATH if unset doesn't work.
8256 * Makefile.in, aclocal.m4, bin/Makefile.in,
8257 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8258 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8259 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8260 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8261 tests/Makefile.in: Regenerate with Automake 1.6.3.
8263 * config/config.guess, config/config.sub, config/mkinstalldirs:
8264 Update.
8266 * configure: Regenerate with self.
8268 2002-08-30 Kevin Ryde <user42@zip.com.au>
8270 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8271 default output.
8273 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8275 * bin/autom4te.in (Request::load): Correctly test for "do" read
8276 failure.
8278 2002-08-29 Akim Demaille <akim@epita.fr>
8280 * lib/Autom4te/General.pm (&xqx): New.
8281 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8282 hand, which is not portable.
8283 (&error): New.
8284 * bin/autom4te.in: Use them.
8285 Use &error instead of die.
8286 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8287 Adjust.
8289 2002-08-17 Paul Eggert <eggert@twinsun.com>
8291 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8292 default list of compilers to try, since it was long ago superseded
8293 by the ksh fc builtin. Suggested by Steven G. Johnson.
8295 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8297 * doc/autoconf.texi (Invoking autom4te): End the option table,
8298 fixing a bug introduced by the previous patch.
8299 (Limitations of Make): Add a 'target lookup' subentry in the
8300 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8302 2002-07-29 Mark D. Roth <roth@feep.net>
8304 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8305 options and use $AUTOM4TE_PATH.
8306 * doc/autoconf.texi: Remove documentation of autom4te
8307 --include-envvar and --site-macro-subdir options and document
8308 use of $AUTOM4TE_PATH.
8309 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8310 arguments from each language section.
8312 2002-07-29 Paul Eggert <eggert@twinsun.com>
8314 * doc/install.texi: Include copyright symbol in copyright notice.
8316 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8317 Replace with:
8318 (AM_MAKEINFOFLAGS): New macro.
8319 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8320 * Makefile.am (INSTALL): Use the new macros.
8321 Use -o rather than --output, since "missing" does not grok --output.
8323 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8325 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8326 comments do not always work. Never trust the exit status of
8327 `make -k'.
8329 2002-07-24 Kevin Ryde <user42@zip.com.au>
8331 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8332 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8334 2002-07-23 Paul Eggert <eggert@twinsun.com>
8336 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8337 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8338 apparently treats PATH="nonexistent" as if it contained ".".
8339 Bug reported by Stefan `Sec' Zehl.
8341 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>

8461 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
8462 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
8463 so that Emacs setups GNU style for perl-mode and cperl-mode.
8465 2002-06-27 Paul Eggert <eggert@twinsun.com>
8467 * config/install-sh: Quote $src. Prefer || to test's -o option,
8468 as per "Limitations of Builtins".
8469 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
8470 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
8472 * tests/mktests.sh: Use grep instead of fgrep, as per
8473 "Limitations of Builtins".
8475 2002-06-15 Paul Eggert <eggert@twinsun.com>
8477 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
8478 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
8479 so that we consistently test the just-built programs.
8480 * tests/wrappl.as: Likewise.

8492 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
8493 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
8494 on Solaris 2.5.1.
8496 2002-06-11 Andreas Schwab <schwab@suse.de>
8498 * doc/autoconf.texi: Add more dir entries.
8500 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
8502 * bin/autom4te.in ($cache): Don't define using `$me', the name
8503 of the cache should not depend on the name under which autom4te
8504 was installed.
8506 2002-06-07 Akim Demaille <akim@epita.fr>
8508 * tests/tools.at (autoconf: forbidden tokens, basic)

8510 words in autom4te.in.
8512 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
8514 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
8515 _AC_LANG_PROGRAM_C_F77_HOOKS.
8517 2002-06-07 Akim Demaille <akim@epita.fr>
8519 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
8520 rename as...
8521 (AC_REPLACE_FNMATCH): this.
8522 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
8523 AC_FUNC_FNMATCH_GNU.
8525 2002-06-07 Akim Demaille <akim@epita.fr>
8527 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
8528 Rosetta Stone for Unix.
8530 2002-06-07 Akim Demaille <akim@epita.fr>
8532 * bin/autom4te.in (warn_forbidden): When rejecting a token,
8533 suggest m4_pattern_allow.
8534 Suggested by Adam J. Richter.
8536 2002-06-07 Akim Demaille <akim@epita.fr>
8538 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
8539 ac_config_libobj_dir.
8540 (AC_CONFIG_LIBOBJ_DIR): New.
8541 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
8542 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
8543 Use ac_config_libobj_dir to find the replacement files.
8544 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
8545 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
8546 (AC_REPLACE_FNMATCH_GNU): these.

8548 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
8549 * tests/mktests.sh (ac_exclude_list): Don't check

8552 2002-06-06 Paul Eggert <eggert@twinsun.com>
8554 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
8555 if ln doesn't work.
8556 * NEWS: Likewise.
8557 * doc/autoconf.texi (Configuration Links): Likewise.
8558 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
8560 2002-06-05 Paul Eggert <eggert@twinsun.com>
8562 * config/config.guess, config/config.sub, config/texinfo.tex:
8563 Update from masters.
8565 2002-05-29 Paul Eggert <eggert@twinsun.com>
8567 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.

8592 2002-05-23 Akim Demaille <akim@epita.fr>
8594 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
8595 version of Autoconf that is discussed.
8597 2002-05-22 Paul Eggert <eggert@twinsun.com>
8599 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
8600 from the default list of compilers to try. Suggested by
8601 Kate Hedstrom.
8602 * NEWS: Document the above.
8603 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
8605 2002-05-17 Paul Eggert <eggert@twinsun.com>
8607 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
8608 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
8609 This improves on an earlier suggestion by H. Peter Anvin.
8611 2002-05-16 Paul Eggert <eggert@twinsun.com>
8613 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
8614 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
8615 Both macros now accept an optional source-dir arg.
8616 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
8618 * NEWS: Document this.
8619 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
8621 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
8622 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
8623 not for GNU extensions; this undoes part of the 2000-11-03 change,
8624 reverting to 2.13-compatible behavior.
8625 Add new optional argument DIR.
8626 (AC_FUNC_FNMATCH_GNU): New macro.
8628 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
8630 2002-05-08 Paul Eggert <eggert@twinsun.com>
8632 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
8633 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
8634 and it causes a 'test' syntax error if it fails.
8635 Bug reported by Stephen Gildea.
8637 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8638 If prototypes are supported, use them to check this at compile-time,
8639 instead of trying to check it at run-time. If we must do a run-time
8640 check, assume that setvbuf is standard when cross-compiling, as
8641 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8642 Bug reported by Paul D. Smith.
8644 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8645 argument specifying location of getloadavg.c. This removes a
8646 FIXME. This idea was taken from Jim Meyering's implementation in
8647 textutils.
8648 * doc/autoconf.texi (Particular Functions): Document this.
8649 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8650 that's what the code does; this fixes a bug reported by
8651 Paul D. Smith.
8653 2002-05-03 Akim Demaille <akim@epita.fr>
8655 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8656 autopoint instead of gettextize.
8657 ($uses_alocal): Rename as...
8658 ($uses_aclocal): this.
8659 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8660 Suggested by Bruno Haible.
8662 2002-05-03 Akim Demaille <akim@epita.fr>
8664 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
8666 2002-04-29 Paul Eggert <eggert@twinsun.com>
8668 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
8669 files to be 1 second older; just set them to be the same time.
8670 Also, sleep 1 second after the first aclocal, to work around
8671 problems with sub-second time stamps on the input files.
8673 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
8675 * doc/autoconf.texi: Mention "set -e -x" lossage
8676 under node "Limitations of Builtins".
8678 2002-04-29 Akim Demaille <akim@epita.fr>
8680 * doc/install.texi: Better wording for setting variables when
8681 running configure.
8682 From Christian Cornelssen.
8684 2002-04-29 Akim Demaille <akim@epita.fr>
8686 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
8687 of lack of $LINENO support, then the test will compare the $LINENO
8688 in testsuite vs. the lineno in the test file. This is wrong, of
8689 course.
8690 Be sure to protect it.
8691 Reported by Patrick Welche.
8693 2002-04-25 Akim Demaille <akim@epita.fr>
8695 * doc/autoconf.texi (Obsolete Macros): Typo.
8696 Reported by Vladimir Volovich.
8698 2002-04-25 Akim Demaille <akim@epita.fr>
8700 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
8701 than some of the input files, hence, on the second run of aclocal,
8702 if some of its input are younger, make them older.
8703 Suggested by Paul Eggert.
8705 2002-04-25 Akim Demaille <akim@epita.fr>
8707 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
8708 Thanks to Paul Eggert.
8710 2002-04-25 Akim Demaille <akim@epita.fr>
8712 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
8713 and ac_subst_vars be sh variables containing the list of
8714 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
8715 DEFAULT diversion.
8716 (_AC_INIT_PREPARE): Use them to log them.
8717 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
8718 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
8719 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
8720 _AC_SUBST_FILES and _AC_SUBST_VARS.
8721 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
8723 2002-04-24 Akim Demaille <akim@epita.fr>
8725 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
8726 autoheader, so that automake does not complain about a missing
8727 config.h.in that was to be created.
8729 2002-04-23 Akim Demaille <akim@epita.fr>
8731 * bin/autoheader.in (parse_args): --warning takes an argument.
8732 Fixes PR/220.
8734 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
8736 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

8751 Reported by Gregory Giannoni.
8753 2002-04-22 Akim Demaille <akim@epita.fr>
8755 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
8756 Fixes false failures on Darwin.

8784 Sample Texts sections of the Texinfo 4.2 manual. Most
8785 importantly, this makes sure that the copyright notices appear in
8786 all output formats. You probably need Texinfo 4.2 to generate

8811 that is not portable to Zsh.
8813 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
8815 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
8816 from aclocal.m4 too.
8818 2002-04-12 Akim Demaille <akim@epita.fr>
8820 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
8822 2002-04-10 Akim Demaille <akim@epita.fr>
8824 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
8825 workaround for ${1+"$@"}.
8826 * doc/autoconf.texi (Shell Substitutions): Explain it.
8827 From Oliver Kiddle and Peter Stephenson.
8829 Have M4sh perform minimal shell sanitizing.
8831 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
8832 part into...
8833 (_AS_PREPARE): this new macro.
8834 (AS_PREPARE): New.
8835 (AS_INIT): Invoke AS_SHELL_SANITIZE.
8836 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
8838 Adjust Autoconf and Autotest.
8840 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
8841 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
8842 * lib/autotest/general.m4 (AT_INIT): Likewise.
8843 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8844 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
8845 AS_SHELL_SANITIZE.
8847 Use this M4sh to generate Autoconf's shell scripts.
8849 * tests/wrapsh.as: New, precursor of wrapsh.in.
8850 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
8851 on Autotest and M4sh.
8852 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
8853 (wrapsh.in): New target.
8854 * bin/autoconf.as: New, precursor of autoconf.in.
8855 (autoconf.in): New target.
8857 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
8859 * doc/autoconf.texi (Limitations of Make): Mention the issue
8860 with indented comments in rules.
8862 2002-04-09 Andreas Schwab <schwab@suse.de>
8864 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
8865 ac_top_builddir when setting ac_abs_top_builddir.

8870 (Portable Shell): Cross reference to Systemology.
8872 2002-04-05 Akim Demaille <akim@epita.fr>
8874 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
8875 directories when descending in a SUBDIRS.
8876 Reported by Ezra Peisach.
8878 2002-04-04 Andreas Schwab <schwab@suse.de>
8880 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
8881 contains no literal separators.
8883 2002-04-03 Akim Demaille <akim@epita.fr>
8885 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
8886 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
8887 Use dnl, not the KILL diversion.
8888 Extracted from...
8889 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8890 (AC_CONFIG_LINKS): here.
8891 Adjust.
8892 Don't use the KILL diversion, as it kills spurious output, which
8893 results in failures being hidden.
8894 Use m4_defn where appropriate.
8895 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8896 after the second argument.
8897 Use m4_defn.
8898 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8899 syntax, as it is provided by M4sugar.
8900 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
8902 2002-04-03 Andreas Schwab <schwab@suse.de>
8904 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not

8913 (_AC_COMPILER_EXEEXT_REJECT): New.
8914 Also recognize *.bb and *.bbg as compilation byproducts.
8915 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
8916 (_AC_COMPILER_OBJEXT): Use them.
8917 Fixes Debian #138666.

8921 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
8923 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
8924 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
8925 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
8926 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
8927 (AC_C_CONST): Same.
8928 (AC_C_INLINE): Same.

8937 _AS_MKDIR_P_PREPARE.
8939 2002-03-28 Kevin Ryde <user42@zip.com.au>
8941 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
8942 to avoid versions of HP C which don't allow that.
8944 2002-03-27 Paul Eggert <eggert@twinsun.com>
8946 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
8947 (AS_SHELL_SANITIZE): Invoke it.
8948 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

8952 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
8954 2002-03-26 Akim Demaille <akim@epita.fr>
8956 * doc/autoconf.texi (Introduction): The GNATS base moved.
8958 2002-03-25 Paul Eggert <eggert@twinsun.com>
8960 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
8961 as POSIX requires, as it doesn't work with Zsh.
8962 * doc/autoconf.texi (Assignments): Document the problem.
8964 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8966 * doc/autoconf.texi (Limitations of Make): Mention more issue
8967 about VPATH, overriding of macros in sub-makes, and handling of
8968 SHELL.
8970 2002-03-21 Paul Eggert <eggert@twinsun.com>
8972 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8973 problem with here-document buffer boundaries.
8975 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8976 when reinvoking the shell, to work around problems with installers
8977 who put strange things like "cd" commands in their environments.
8979 2002-03-19 Akim Demaille <akim@epita.fr>
8981 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
8982 From Aaron Ucko.
8984 2002-03-19 Akim Demaille <akim@epita.fr>
8986 * bin/autoscan.in (scan_file): Specify the location in `&used'
8987 invocations.
8988 From Nicolas Joly.
8990 2002-03-19 Akim Demaille <akim@epita.fr>
8992 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
8993 From Nishio Futoshi.
8995 2002-03-19 Akim Demaille <akim@epita.fr>
8997 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
8999 2002-03-18 Paul Eggert <eggert@twinsun.com>
9001 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9002 (Limitations of Usual Tools): Add mkdir section.
9004 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9005 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9006 back on AS_DIRNAME to compute prefixes otherwise; this is
9007 roughly what mkinstalldirs does. That way, we need not have
9008 our own filename disassembler. The old disassembler did not
9009 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9011 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9012 Create at_test_all by a series of assignments,
9013 not by a single assignment of a long string. The latter causes ksh
9014 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9015 presumably because of a buffer overrun.
9017 2002-03-14 Paul Eggert <eggert@twinsun.com>
9019 * lib/autotest/general.m4 (at_times_skip):
9020 Renamed from at_times. Now a boolean.
9021 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9022 says 'times: not found'.
9024 2002-03-14 Akim Demaille <akim@epita.fr>
9026 * bin/autoreconf.in (&study_gettextize): New.
9027 (&autoreconf): Handle newest gettextize.
9028 Rerun aclocal if needed.
9029 Suggested by Andreas Schwab.
9031 2002-03-13 Akim Demaille <akim@epita.fr>
9033 * doc/autoconf.texi (Special Shell Variables): More about IFS.
9035 2002-03-13 Akim Demaille <akim@epita.fr>
9037 * doc/autoconf.texi (Header Portability): New.
9038 Add information about stdint.h and inttypes.h from Paul Eggert.
9040 2002-03-13 Akim Demaille <akim@epita.fr>
9042 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9043 -p'.
9044 From Bob Proulx.
9046 2002-03-12 Akim Demaille <akim@epita.fr>
9048 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9049 m4_require.
9051 2002-03-11 Andreas Schwab <schwab@suse.de>
9053 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9054 does not do it if --with-lispdir is given.
9056 2002-03-08 Akim Demaille <akim@epita.fr>
9058 Version 2.53.
9060 2002-03-08 Akim Demaille <akim@epita.fr>
9062 * doc/autoconf.texi (Subdirectories): Clarify that the
9063 subdirectory should exist.
9065 2002-03-08 Akim Demaille <akim@epita.fr>
9067 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9069 2002-03-08 Akim Demaille <akim@epita.fr>
9071 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9072 aliases the actual variables, and modifications of the former
9073 affect the latter.
9075 2002-03-08 Akim Demaille <akim@epita.fr>
9077 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9078 because of C-c: have m4 output in tmp files, then mv them.
9080 2002-03-08 Akim Demaille <akim@epita.fr>
9082 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9083 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
9084 * bin/ifnames.in: Copyright update.
9086 2002-03-08 Akim Demaille <akim@epita.fr>
9088 * doc/autoconf.texi (Invoking autom4te): New.
9090 2002-03-05 Akim Demaille <akim@epita.fr>
9092 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9093 Kevin Ryde.
9095 2002-03-05 Akim Demaille <akim@epita.fr>
9097 Version 2.52i.
9099 2002-03-04 Akim Demaille <akim@epita.fr>
9101 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9102 * lib/autoconf/general.m4 (AC_INIT): More informative error
9103 message for LIBOBJ.
9105 2002-03-04 Akim Demaille <akim@epita.fr>
9107 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9108 parallel builds.
9110 2002-03-04 Akim Demaille <akim@epita.fr>
9112 * doc/autoconf.texi (Transforming Names): Equality between target
9113 and host is irrelevant.
9114 (Specifying Names, Canonicalizing): Remove all references to the
9115 backward compatibility hooks. Rather, collect them all into...
9116 (Hosts and Cross-Compilation): this new section.
9117 * doc/install.texi (System Type): Ditto.
9118 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9119 that `--host' implies cross-compilation.
9121 2002-03-04 Akim Demaille <akim@epita.fr>
9123 * doc/autoconf.texi (Evaluation Macros): New.
9124 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9125 useless.
9126 (_m4_foreach): Define the variant with immediate evaluation so
9127 that it contains exactly the items, not an expression which
9128 evaluation is the current item.
9129 (m4_re_string, m4_re_word): Don't over quote them.
9131 2002-03-04 Akim Demaille <akim@epita.fr>
9133 Instead of having stacking `shift's evaluated at the end, let
9134 `foreach' loops immediately evaluate them.
9136 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9137 $*. This is the n-th time I change my mind, but hopefully this is
9138 the last...
9139 (m4_lquote): New.
9140 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9141 efficient.
9142 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9143 it was only a hack for m4_text_wrap.
9144 (m4_car2): Remove, replaced by...
9145 (m4_cdr): New.
9146 (_m4_foreach): Adjust.
9147 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9148 m4_bpatsubst for clarification.
9150 2002-03-04 Akim Demaille <akim@epita.fr>
9152 * doc/autoconf.texi (Changequote is Evil): New.
9154 2002-03-03 Kevin Ryde <user42@zip.com.au>

9157 on old systems like SunOS.
9159 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
9161 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,

9170 message to be sent.
9172 2002-02-28 Kevin Ryde <user42@zip.com.au>

9176 2002-02-25 Akim Demaille <akim@epita.fr>
9178 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
9179 From Akinori Musha.
9181 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
9183 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
9184 translate \r\n to \n.
9186 2002-02-07 Akim Demaille <akim@epita.fr>
9188 Version 2.52h.
9190 2002-02-07 Akim Demaille <akim@epita.fr>
9192 Fix Autoconf PR/209.
9193 Also reported by Frank Denis.
9195 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
9197 2002-02-07 Akim Demaille <akim@epita.fr>
9199 Fix Autoconf PR/207:
9200 AC_PREFIX_PROGRAM fails with dashed program names
9202 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9203 variable when looking for the prefix program.
9204 Now it also works for shell variables.
9206 2002-02-07 Akim Demaille <akim@epita.fr>
9208 * doc/autoconf.texi (Limitations of Builtins): More about
9209 case/esac.
9211 2002-02-06 Akim Demaille <akim@epita.fr>
9213 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
9214 case/esac, some shells don't support it.
9215 Reported by Zack Weinberg.
9216 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
9218 2002-02-06 Akim Demaille <akim@epita.fr>
9220 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9221 sure not to introduce newlines in at_groups.
9222 * lib/autotest/Makefile.am (autotest.m4f): Typo.
9224 2002-02-06 Akim Demaille <akim@epita.fr>
9226 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9227 is not available.
9229 2002-02-05 Paul Eggert <eggert@twinsun.com>
9231 * doc/autoconf.texi (Specific Compiler Characteristics):
9232 Describe HP-UX cc bug workaround more accurately.
9233 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
9234 not unsigned long.
9235 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9236 cross-compilers, too. This undoes some of the most recent change
9237 to this file.
9239 2002-02-05 Akim Demaille <akim@epita.fr>
9241 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9242 to make sure they are up to date when `check' is run.
9244 2002-02-05 Akim Demaille <akim@epita.fr>
9246 * doc/autoconf.texi (Making testsuite Scripts): Document
9247 package.m4.
9249 2002-02-05 Akim Demaille <akim@epita.fr>
9251 * lib/freeze.mk: New.
9253 2002-02-05 Akim Demaille <akim@epita.fr>
9255 Implement `autom4te --freeze'.
9257 * bin/autom4te.in (&freeze): New.
9258 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9259 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9261 2002-02-05 Akim Demaille <akim@epita.fr>
9263 * bin/autom4te.in (&parse_args): Implement `frozen files are
9264 optional are the sum of the previous files on the command line'.
9265 Also, pass `--reload-state=' on them, so...
9266 (handle_m4): don't.
9267 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9268 (M4sh): Rely on M4sugar.
9269 (Autotest, M4sh, M4sugar): Use frozen files.
9271 2002-01-31 Akim Demaille <akim@epita.fr>
9273 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
9274 * doc/autoconf.texi (Initializing configure): Adjust.
9276 2002-01-30 Akim Demaille <akim@epita.fr>
9278 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9279 alphanumeric to `-' instead of `_'.
9281 2002-01-30 Akim Demaille <akim@epita.fr>
9283 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9284 for plain code, the other for cross-compilation code. The latter
9285 is now run with GCC only.
9286 * doc/autoconf.texi (Compilers and Preprocessors): New.
9288 2002-01-30 Akim Demaille <akim@epita.fr>
9290 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
9291 values.
9292 * doc/autoconf.texi (Initializing configure): Explain how to
9293 change AC_INIT default values.
9295 2002-01-29 Akim Demaille <akim@epita.fr>
9297 * tests/torture.at (Configuring subdirectories): Use configure.in,
9298 so that aclocal 1.4 works.
9299 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9301 2002-01-28 Akim Demaille <akim@epita.fr>
9303 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9304 needs an argument.
9306 2002-01-28 Akim Demaille <akim@epita.fr>
9308 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9309 AUTOTEST_PATH *after* it was set.
9310 Don't put `.' in the PATH: the user should be precise and `./' if
9311 needed. In addition, given that the test suite does some `cd', if
9312 `.' is in the path, the `tested programs' sections will report
9313 programs found in the test suite's directory, while during the
9314 tests (performed in their own directory), these programs are no
9315 longer visible. In other words, the results is confusing and
9316 useless.
9317 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9319 2002-01-24 Akim Demaille <akim@epita.fr>

9382 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
9383 package.m4, since is really depends upon configure.ac, not
9384 configure.
9385 * doc/autoconf.texi (testsuite Scripts): Adjust.
9386 * tests/Makefile.am (package.m4): New.
9387 EXTRA_DIST it since its a source.
9389 2002-01-06 Akim Demaille <akim@epita.fr>
9391 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9392 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9393 and PACKAGE_BUGREPORT from here...
9394 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9395 arguments.

9421 2001-12-14 Akim Demaille <akim@epita.fr>
9423 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9424 trailing files, don't apply `-rf' to files which might not be
9425 created by configure (core, core.*, and *.core), but just `rm -f'.
9426 Suggested by Jonathan Kamens.
9428 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9430 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

9439 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
9440 abs_srcdir, top_srcpath to abs_top_srcdir.
9441 (_AC_OUTPUT_FILES): Adjust.
9442 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
9443 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
9444 * tests/wrappl.in, tests/wrapsh.in: Adjust.
9446 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
9448 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed

9452 2001-12-12 Kevin Ryde <user42@zip.com.au>
9454 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
9455 forbidden file descriptors table.
9457 2001-11-26 Akim Demaille <akim@epita.fr>
9459 * bin/autoscan.in (%c_keywords): Build it at top level.

9462 2001-11-26 Akim Demaille <akim@epita.fr>
9464 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
9465 Remove $filepath, useless.
9466 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
9467 variables, they are really part of the tokens.
9468 Split the input line on spaces and then look for tokens.
9469 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9470 because of `lex$U.$(OBJEXT)'.
9471 (&scan_files): Use "@list" instead of join.
9472 * doc/Makefile.am (CLEANFILES): Add *.fns.
9474 2001-11-26 Akim Demaille <akim@epita.fr>

9483 2001-11-26 Akim Demaille <akim@epita.fr>
9485 * bin/autoscan.in (used): New.
9486 Use it.
9488 2001-11-26 Akim Demaille <akim@epita.fr>
9490 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
9491 directives.
9492 (&scan_sh_file): Remove a duplicate pattern.
9493 (&check_configure_ac): Use long options.
9494 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
9496 2001-11-26 Akim Demaille <akim@epita.fr>
9498 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
9499 Before, having a line containing the opening of a multi line
9500 comment made the whole line be ignored.
9502 2001-11-26 Akim Demaille <akim@epita.fr>
9504 * doc/autoconf.texi (Using an Autotest Test Suite): New.
9505 (testsuite Scripts): Be one of its subsection.
9506 (Autotest Logs): New.
9508 2001-11-26 Akim Demaille <akim@epita.fr>
9510 Test groups are now run two directories deeper.
9512 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
9513 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
9514 at_top_builddir.
9515 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
9516 top_srcdir, builddir and top_builddir.
9517 Use `at_*dir' relatively to the directory containing the
9518 suite, use `*dir' when relatively to the current group dir.
9520 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
9522 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
9523 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
9524 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
9525 spelling errors.
9527 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9529 * doc/autoconf.texi (Using System Type): Add an example of `case
9530 $host' usage so people quit using `case $target' everywhere.
9532 2001-11-22 Akim Demaille <akim@epita.fr>
9534 * doc/autoconf.texi (Installation Directory Variables): Englishoes
9535 spotted by Jim Meyering.
9537 2001-11-16 Paul Eggert <eggert@twinsun.com>
9539 This patch implements a `long double' suggestion by Oliver Kiddle.
9541 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9542 static, to catch errors if the value isn't known at compile-time
9543 and the compiler supports dynamic arrays. Change its name from
9544 `_array_' to `test_array' to avoid potential name clashes.
9545 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9546 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9547 better than double. Catch a bug in GCC 2.95.2 x86.
9548 * doc/autoconf.texi (C Compiler): Document the above.
9549 * NEWS: Likewise.
9551 2001-11-13 Akim Demaille <akim@epita.fr>
9553 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9554 hand.
9555 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9557 2001-11-13 Akim Demaille <akim@epita.fr>
9559 * lib/autotest/general.m4 (AT_INIT): After having run the test
9560 group, go back to the initial directory, not to at_suite_dir.
9562 2001-11-13 Akim Demaille <akim@epita.fr>
9564 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9565 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9566 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9567 option.
9568 (AT_CHECK_CONFIGURE): Use absolute paths.
9569 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9570 The problem is still the old one: there is no means in M4 (that I
9571 know about) to create a defining macro, because there is no means
9572 to create `$1' etc., therefore, the defining macro ``swallows''
9573 all the arguments meant to the defined macro.
9575 2001-11-13 Akim Demaille <akim@epita.fr>
9577 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9578 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9579 configure.ac.
9580 * tests/aclocal.m4: Remove, as it is no longer used.
9582 2001-11-13 Akim Demaille <akim@epita.fr>
9584 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9585 variable names when referring to a single test group, or to
9586 `suite' when referring to the whole test suite.
9587 `at_last_test' is removed: m4 compute at_format itself.
9588 (at_stdout, at_stder1, at_stderr): New variables.
9589 (AT_CHECK): Use them.
9591 2001-11-13 Akim Demaille <akim@epita.fr>
9593 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9594 in PATH.
9595 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9596 Do it as soon as a test fails, don't wait till the end of the test
9597 suite.
9598 Don't remove $as_me.[0-9]*, since these files no longer exist.
9600 2001-11-13 Akim Demaille <akim@epita.fr>
9602 * tests/tools.at: Use absolute paths, since we are no longer run
9603 in place.
9605 2001-11-13 Akim Demaille <akim@epita.fr>
9607 Now that tests are running in their own private dir, there is no
9608 need to list the files to remove at the end of tests groups.
9610 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
9611 (AT_data_files, at_data_files): Remove.
9612 (AT_CLEANUP, AT_DATA): Simplify.
9613 (AT_INIT): Adjust.
9614 Remove the group dir if !debug && !failed.
9615 * tests/atspecific.m4: Adjust.
9617 2001-11-13 Akim Demaille <akim@epita.fr>
9619 Start a new layout for Autotest: `testsuite' creates
9620 `testsuite.dir' in which the at-check-line etc. files are to be
9621 found, and `testsuite.dir/003' where the test group 3 is run.
9623 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
9624 at_check_line_file, at_format, at_test_normalized, at_group_dir
9625 are new variables.
9626 Create the directories.
9627 Use absolute paths for at- files.
9628 (AT_CHECK): Adjust.
9630 2001-11-11 Michael Matz <matz@kde.org>
9632 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
9633 (m4_car2): New.
9634 (m4_car): Properly quote arguments.
9636 2001-11-13 Akim Demaille <akim@epita.fr>
9638 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9639 with stricter rules on LIBOBJS.
9641 2001-11-12 Paul Eggert <eggert@twinsun.com>
9643 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9644 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9645 __PROTOTYPES too.
9647 2001-11-12 Akim Demaille <akim@epita.fr>
9649 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9651 2001-11-12 Akim Demaille <akim@epita.fr>
9653 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9654 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
9655 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9656 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9657 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9658 specify to what the macro should be defined (typically to 1).
9660 2001-11-12 Akim Demaille <akim@epita.fr>
9662 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9663 From Jim Meyering.
9665 2001-11-12 Akim Demaille <akim@epita.fr>
9667 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9668 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
9669 definition used by Automake where LEX is +/- "${missing} lex" and
9670 `missing' itself contains variables.
9672 2001-11-12 Akim Demaille <akim@epita.fr>
9674 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
9675 Now that M4sh pushes BODY, the comments were output at the end of
9676 the test suites.
9678 2001-11-08 Akim Demaille <akim@epita.fr>
9680 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
9681 that we can trace macros from aclocal.m4.
9682 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
9683 obsoleted, and redirect to the former anyway.
9684 Reported by Ralf Corsepius.
9686 2001-11-08 Akim Demaille <akim@epita.fr>
9688 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
9689 processed only if present.
9690 * tests/torture.at (Configuring subdirectories): Use autoreconf
9691 instead of successive calls to autoconf.
9692 Add a nonexistent subdirectory to exercise the patch above.
9693 Reported by Ralf Corsepius.
9695 2001-11-08 Kevin Ryde <user42@zip.com.au>
9697 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
9698 doesn't accept .S files.
9700 2001-11-07 Akim Demaille <akim@epita.fr>
9702 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
9703 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
9704 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
9705 * bin/autom4te.in (warn_forbidden): New.
9706 (handle_output): Use it.
9707 Read m4_pattern_forbid with messages.
9709 2001-11-05 Akim Demaille <akim@epita.fr>
9711 * bin/autom4te.in (--normalize): Remove.
9712 * lib/autom4te.in: Adjust.
9714 2001-11-05 Akim Demaille <akim@epita.fr>
9716 * tests/Makefile.am (testsuite): Rename this target as...
9717 ($(TESTSUITE)): this.
9718 From Nicolas Joly.
9720 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
9722 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
9723 the --prefix option, also remove it's argument.
9725 2001-11-05 Akim Demaille <akim@epita.fr>
9727 * doc/autoconf.texi (testsuite Invocation): Update.
9728 (Writing testsuite.at): Update.
9730 2001-11-03 Akim Demaille <akim@epita.fr>
9732 * doc/autoconf.texi: s/@code/@command/ where appropriate.
9734 2001-11-03 Akim Demaille <akim@epita.fr>
9736 * lib/Autom4te/General.pm: (&catfile, &canonfile)
9737 (&file_name_is_absolute): New, wrappers around routines from
9738 File::Spec.
9739 Use and export them.
9740 (&find_configure_ac): Optionally take a directory where to look at.
9741 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
9742 the arguments.
9743 Default @ARGV to `.', not find_configure_ac.
9744 (&autoreconf): Argument is a directory.
9745 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
9746 * doc/autoconf.texi (autoreconf Invocation): Update.
9748 2001-11-03 Akim Demaille <akim@epita.fr>
9750 * lib/Autom4te/General.pm (@export_vars, @export_subs)
9751 (@export_forward_subs): New.
9752 Add basename, dirname, and fileparse.
9753 (@EXPORT): Adjust.
9754 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
9755 Don't look for aclocal flags if we already know aclocal is not
9756 used.
9757 Move aclocal.m4t only if it exists.
9758 Reported by Ezra Peisach.
9760 2001-11-03 Akim Demaille <akim@epita.fr>
9762 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
9763 passed on command line, defaulting to ./configure.ac if present.
9764 (&maybe_autoreconf, File::Find): Remove, unused.
9765 (&autoreconf): If autoconf is not used, don't try to trace.
9767 2001-11-02 Akim Demaille <akim@epita.fr>
9769 * configure.ac: Bump to 2.52g.
9771 2001-11-02 Akim Demaille <akim@epita.fr>
9773 Version 2.52f.
9775 2001-11-02 Akim Demaille <akim@epita.fr>
9777 * config/config.guess, config/config.sub, doc/standards.texi:
9778 * config/lispdir.m4: Update from masters.

9783 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
9784 Don't run aclocal when aclocal.m4 is not from aclocal.
9785 From Ezra Peisach.
9786 Don't run libtoolize and gettextize if --install is not given.
9788 2001-11-01 Paul Eggert <eggert@twinsun.com>
9790 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
9791 be invoked before _AS_LINENO_PREPARE.
9792 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9793 than character ranges.
9795 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9796 invoking AS_BASENAME. Set the locale variables to 'C' if
9797 possible, as POSIX requires this to get the traditional
9798 behavior.
9799 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9801 2001-10-31 Paul Eggert <eggert@twinsun.com>
9803 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9804 with {}, as that triggers a bug in Bash 2.05.
9806 (_AS_LINENO_PREPARE): Use Sed rather than
9807 Awk. Fix the sed prepass to work even if there are multiple
9808 instances of $LINENO on the same line. Do not substitute for
9809 other variables like $LINENOT. Do not check file dates; such a
9810 check is unreliable on sufficiently fast machines, and removing
9811 the check makes the code simpler and more reliable. Check for
9812 output and chmod failures.
9814 * doc/autoconf.texi (Special Shell Variables): Document
9815 the above.
9817 2001-10-31 Akim Demaille <akim@epita.fr>
9819 * tests/Makefile.am (atconfig): Remove this target, Automake
9820 handles it now.
9822 2001-10-31 Akim Demaille <akim@epita.fr>
9824 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
9825 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
9826 provided, while it is optional.
9827 * configure.ac: Adjust.
9829 2001-10-26 Paul Eggert <eggert@twinsun.com>
9831 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
9832 lib/Autom4te/Struct.pm:
9833 Require Perl 5.005_03 instead of just 5.005, as some tests fail
9834 with 5.005_02.
9836 * doc/autoconf.texi (Special Shell Variables): Document some
9837 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
9839 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
9840 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
9841 eval $LINENO is not portable in practice.
9843 2001-10-24 Akim Demaille <akim@epita.fr>
9845 * lib/Autom4te/General.pm (backname): New.
9847 2001-10-24 Akim Demaille <akim@epita.fr>

9857 2001-10-22 Paul Eggert <eggert@twinsun.com>
9859 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
9860 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
9861 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
9862 POSIX decided to standardize on the int flavor of strerror_r.
9863 Always do char* test, as there's no reason not to.
9864 Assign to a char* var, to catch strerror_r that returns int*.
9866 * doc/autoconf.texi (Particular Functions):
9867 Document the above changes. Also, document the fact that
9868 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
9870 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
9872 2001-10-20 Akim Demaille <akim@epita.fr>

9877 2001-10-20 Akim Demaille <akim@epita.fr>
9879 * lib/Autom4te/General.pm (&update_file): If destination is
9880 unchanged, remove the source.

9883 (&autoreconf): Display the full path of the configure.ac we are
9884 studying.
9885 Trace it only once.
9886 Be sure to honor --force with gettextize.
9887 Always run aclocal.
9888 * doc/autoconf.texi: Adjust.
9890 2001-10-20 Akim Demaille <akim@epita.fr>
9892 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9893 Remove, dead.
9894 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9895 `intl' is already present, as it refuses unless --force.
9896 (&parse_args): Use -I, --include instead of the old Autoconf
9897 options.
9898 ($localdir, $autoconf_dir): Remove.
9899 (@include): New.
9900 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9902 2001-10-19 Jens Petersen <petersen@redhat.com>
9904 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

9923 configure.ac being studied.
9925 2001-10-18 Paul Eggert <eggert@twinsun.com>
9927 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
9928 long, to work around a bug in the HP C compiler version HP92453-01
9929 B.11.11.23709.GP.
9931 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
9932 (AS_BASENAME_EXPR): New macro.
9933 (AS_BASENAME_SED): Do not assume GNU sed semantics.
9934 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
9935 and fall back on 'sed' only if the other two fail. This makes
9936 AS_BASENAME act more like AS_DIRNAME.
9937 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
9938 contains white space.
9939 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
9940 Use AS_DIRNAME, since I think it's now DOS-friendly.
9941 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9942 Allow "dirname //FOO" to return either / or //, as POSIX allows
9943 either behavior.
9945 2001-10-10 Akim Demaille <akim@epita.fr>
9947 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
9948 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
9949 From Eric Sharkey.

9953 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

9991 (Syntax of the shell scripts): Don't.
9992 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
9993 bother with $force since...
9994 * lib/Autom4te/General.pm: does.
9996 2001-10-08 Akim Demaille <akim@epita.fr>
9998 * bin/autoreconf.in: Rewrite in Perl.
9999 * configure.ac: Adjust.

10082 shell does not support LINENO, and if CONFIG_SHELL is unset or
10083 empty, and if we can find a shell that does support LINENO,
10084 then set CONFIG_SHELL to that shell and then re-execute
10085 ourselves with CONFIG_SHELL.
10087 2001-10-05 Paul Eggert <eggert@twinsun.com>
10089 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
10090 doesn't exist. Remove *.tmp, as a .tmp file is created during the
10091 build of $(TESTSUITE).
10093 2001-10-05 Akim Demaille <akim@epita.fr>
10095 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

10161 Don't use nested parenthesization. This patch was originally

10163 but somehow it didn't get incorporated then.
10164 * doc/autoconf.texi (Limitations of Usual Tools):
10165 Clarify remark about sed and nested parenthesization.
10167 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):

10169 the type exists.
10170 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10171 Check for `expr' arithmetic overflow, and for compilation failure,
10172 and invoke a new argument $4 if either is discovered.
10173 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
10174 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
10176 2001-09-28 Akim Demaille <akim@epita.fr>

10206 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
10207 (AC_PROG_CPP requires AC_PROG_CC): here and...
10208 * tests/fortran.at (GNU Fortran 77): there.
10209 * doc/autoconf.texi (autoconf Invocation): Fix the example:
10210 AC_TRY_RUN is about compilation, not shell commands.

10215 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
10216 Raja R Harinath:
10217 Be sure to detect when $LINENO always returns the same value.
10218 Look for the original script, basename($0) is certainly not
10219 enough.
10220 Pass the CLI arguments to `$as_me.lineno'.

10317 2001-09-22 Akim Demaille <akim@epita.fr>
10319 Rely on `$LINENO' when possible instead of `__oline__'.
10321 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
10322 `$LINENO' support replacement when not supported.
10323 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
10324 them explicitly to be sure they are not output before this section
10325 (via m4_require). Cosmetic only.
10326 * lib/autoconf/c.m4, lib/autoconf/general.m4,
10327 * lib/autoconf/programs.m4: Replace all the occurrences of

10331 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>

10334 character (u: -> ue) in a code comment.
10335 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
10336 it works.
10338 2001-09-21 Akim Demaille <akim@epita.fr>
10340 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
10341 Suggested by Jim Meyering.

10358 PATH_SEPARATOR.
10359 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

10365 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10367 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
10368 arguments. Fixed a typo.
10370 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10372 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

10384 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10386 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10387 already have $file). Set output files to binary mode (helps avoid
10388 CR issues on DOSish systems).
10390 2001-09-19 Akim Demaille <akim@epita.fr>
10392 * lib/autotest/general.m4: Englishoes.
10393 From Tim Van Holder and Alexey Mahotkin.
10395 2001-09-18 Paul Eggert <eggert@twinsun.com>
10397 * doc/autoconf.texi (Common Shell Constructs): New node,
10398 documenting AS_DIRNAME.
10399 (Limitations of Usual Tools): Refer to it when discussing dirname.
10400 Also, update discussion of POSIX standard to reflect latest draft.
10402 * lib/autoconf/c.m4:
10403 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
10405 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10406 Do not pass a first argument with leading '-'
10407 to expr, by parenthesizing initial integers that might be negative.
10409 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10410 now merely checks whether it is an error to pass an argument
10411 to getpgrp.
10413 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10414 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
10415 whether it is a (compile-time) error to pass an argument to
10416 getpgrp. This simpler test supports the revised documentation,
10417 and is all that AC_FUNC_GETPGRP's users really need.
10419 2001-09-18 Akim Demaille <akim@epita.fr>
10421 * doc/autoconf.texi (Limitations of Make) <$<>: New.

10431 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
10432 correctly.
10433 Add test for AS_BASENAME.
10434 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10435 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10436 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10437 * tests/base.at: Fixed the expected responses. The old ones were
10438 one line out...
10439 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10440 the documentation claims it should (and how it behaved in 2.13).
10442 2001-09-18 Akim Demaille <akim@epita.fr>
10444 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
10445 the AC_CONFIG_COMMANDS invocation.
10446 This also solves the name clash problems.
10447 Don't set the package's ID.
10448 * lib/m4sugar/Makefile.am (version.m4): Revamp.
10449 No longer to be shipped.
10450 (version.in): Remove.
10451 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
10452 * lib/autoconf/status.m4: Adjust.
10453 Use `m4_PACKAGE_STRING'.
10454 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
10455 the only optional argument is the name of the test suite.
10456 Expect `package.m4' to define the package signature.
10457 * lib/autom4te.in (Autotest): Add `package.m4?'.
10458 * tests/Makefile.am (package.m4): New.
10459 * tests/suite.at: ifnames is a victim.
10461 2001-09-18 Akim Demaille <akim@epita.fr>
10463 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
10464 AC_LIBSOURCE, AC_CONFIG_FILES.
10465 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
10466 program version string doesn't match the package's.
10467 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
10468 after `(cached)'.

10472 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10473 Allow expression to return any value that can fit into unsigned long
10474 (not int, as before). Check for output errors.
10476 2001-09-17 Bruno Haible <haible@ilog.fr>
10478 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10479 Always include <stdio.h> and <stdlib.h>. Evaluate
10480 the expression in an extra function before these includes. Call
10481 fprintf "%d" only after ensuring the argument is of type 'int'.
10482 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
10484 2001-09-17 Paul Eggert <eggert@twinsun.com>
10486 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10487 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10488 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10489 when they don't exist.
10491 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
10492 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
10493 need it.
10495 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
10496 version with the version used by fileutils 4.1, except use
10497 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
10498 we don't need it.
10500 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
10502 2001-09-13 Akim Demaille <akim@epita.fr>
10504 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
10505 _first_.
10506 Reported by Gerrit P. Haase.

10510 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

10542 * lib/autotest/general.m4 (AT_INIT): Create and remove
10543 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
10544 test suites can cohabit.
10546 2001-09-13 Akim Demaille <akim@epita.fr>
10548 * tests/mktests.sh: Don't output banners for empty test files.
10550 2001-09-13 Akim Demaille <akim@epita.fr>
10552 Test suites can be run independently of configure.

10633 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
10634 in addition, it introduces useless differences in logs.

10647 to avoid GCC warnings.
10648 From Uwe Seimet.
10650 2001-09-05 Akim Demaille <akim@epita.fr>
10652 * bin/autom4te.in: --language is -l, not -s.
10654 2001-09-05 Akim Demaille <akim@epita.fr>

10660 excellence in M4 quotation: consider `__file__' is active.

10716 2001-08-31 Akim Demaille <akim@epita.fr>
10718 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
10719 (Making testsuite Scripts): Update.
10721 2001-08-31 Akim Demaille <akim@epita.fr>
10723 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
10725 2001-08-31 Akim Demaille <akim@epita.fr>
10727 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
10728 (testsuite Scripts): There is no such thing as `atconfig.in'.
10729 And actually one diagram is missing: test suite runtime.
10731 2001-08-31 Akim Demaille <akim@epita.fr>
10733 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
10734 inverse order.
10736 2001-08-31 Akim Demaille <akim@epita.fr>
10738 * bin/autoupdate.in (@include): `installcheck' revealed the path
10739 to m4sugar was lacking!
10741 2001-08-31 Akim Demaille <akim@epita.fr>
10743 * man/Makefile.am (.x.1): We really have to pass
10744 autom4te_perllibdir.
10746 2001-08-31 Akim Demaille <akim@epita.fr>
10748 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
10749 debug scripts, in particular passing explicitly listed tests to
10750 run is stupid.
10752 2001-08-31 Akim Demaille <akim@epita.fr>
10754 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
10755 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
10756 Use directly autom4te, not autoconf.
10757 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
10759 2001-08-31 Akim Demaille <akim@epita.fr>
10761 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
10762 * bin/autoheader.in (%symbol): Strip arguments of macros.
10764 2001-08-31 Akim Demaille <akim@epita.fr>
10766 * doc/autoconf.texi: Catch up -I, --include changes.
10768 2001-08-31 Akim Demaille <akim@epita.fr>
10770 * bin/autom4te.in (&parse_args): Die on unknown languages.
10771 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
10772 need for autoconf.
10773 Promote --include over --macrodir and other obsolete options.
10775 2001-08-31 Akim Demaille <akim@epita.fr>
10777 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
10778 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
10779 * bin/autom4te.in ($autoconf): Pass --force.
10780 `print $out' doesn't print `$_' but `$out'.
10781 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
10782 (autoheader): Pass --force since the test suite goes too fast for
10783 the time stamps.
10784 Adjust to the new autoheader messages.
10786 2001-08-31 Akim Demaille <akim@epita.fr>
10788 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
10789 Check the completeness of the #template.
10790 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
10791 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
10792 invocation.
10794 2001-08-31 Akim Demaille <akim@epita.fr>
10796 * lib/Autom4te/General.pm (&find_file, &update_file): New.
10797 * bin/autoupdate.in, bin/autoheader.in: Adjust.
10798 Drop AC_MACRODIR dead for real.
10799 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
10800 `autoheader: `config.hin' is created'.
10801 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
10803 2001-08-31 Akim Demaille <akim@epita.fr>
10805 * bin/autoheader.in: Rewrite in Perl.
10806 * tests/autoheader: Adjust.
10808 2001-08-31 Akim Demaille <akim@epita.fr>
10810 * bin/autoconf.in (--include, -I): New option.
10811 Map --localdir, --autoconf-dir onto it.
10812 Forward autom4te's options instead of interpreting them.
10813 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
10814 There is no such envvar since the inception of autom4te.cfg.
10815 * bin/autom4te.in (&parse_args): Uniquify `@include'.
10816 * bin/autoupdate.in: Adjust, and perform more control.
10817 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
10818 * tests/autoconf: Dittowise.
10820 2001-08-31 Akim Demaille <akim@epita.fr>
10822 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
10823 * bin/autom4te.in (&find_file): Support `FILE?' standing for
10824 optionally `FILE'.
10825 Use -e, not -f, since /dev/null for instance is OK.
10826 (&parse_args): Adjust.
10827 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
10829 2001-08-31 Akim Demaille <akim@epita.fr>
10831 * configure.ac: Also find tested executables in bin.
10832 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
10833 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
10834 installed peer executables, only PATH is allowed to resolve it.
10835 Pass `autoconf_dir' via options, not via invisible envvars.
10836 * lib/Autom4te/General.pm (&find_peer): Remove.
10837 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
10838 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
10839 * man/Makefile.am: Let help2man rely on PATH instead of trying to
10840 find the executables for it.
10841 * tests/Makefile.am: Major cleanup. Too lazy to document...
10842 * tests/atlocal.in: Remove all the obscure envvar manipulations.
10843 We only need PERL.
10844 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
10845 indeed related to running the test suite, while passing
10846 --autoconf-dir and others is related to running non installed
10847 Autoconf executables. So don't do that, leave it to...
10848 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
10849 * tests/autoscan: New.
10850 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
10851 refer to library files: rely on --language.
10853 2001-08-29 Akim Demaille <akim@epita.fr>
10855 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
10856 s/--set/--language/.
10858 2001-08-29 Akim Demaille <akim@epita.fr>
10860 * doc/autoconf.texi: Strip the @nodes.
10861 Suggested by Paul Eggert.
10862 (Initializing configure): Typo.
10864 2001-08-29 Akim Demaille <akim@epita.fr>
10866 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
10867 Suggested by Paul Eggert.
10869 2001-08-29 Akim Demaille <akim@epita.fr>
10871 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
10872 download in a tmp dir.
10874 2001-08-29 Akim Demaille <akim@epita.fr>
10876 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
10877 case insensitive OSes out there :(
10878 From Tim Van Holder.
10880 2001-08-29 Akim Demaille <akim@epita.fr>
10882 * lib/autom4te.in: New.
10883 * lib/Makefile.am (edit, autom4te.cfg): New.
10884 * bin/autom4te.in (BEGIN): Simplify.
10885 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
10886 (&load_configuration): New. Use it.
10887 (&parse_args): Support --mode, --set, and --melt.
10888 * bin/autoconf.in: Simplify and adjust.
10889 * tests/Makefile.am (AUTOMAKE): Use --set.
10890 * tests/atlocal.in: Adjust.
10891 * BUGS: distcheck and check are weak.
10893 2001-08-29 Akim Demaille <akim@epita.fr>
10895 * lib/autotest/general.m4: Use
10896 foo=`(command) 2>/dev/null`
10897 not
10898 foo=`command` 2>/dev/null
10899 (at-devnull): Rename as...
10900 (AT-devnull): this.
10901 (--clean): Remove AT-* files too.
10902 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
10903 Reported by Nicolas Joly.
10905 2001-08-28 Akim Demaille <akim@epita.fr>
10907 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
10908 quotes inside single quotes.
10909 Reported by Nicolas Joly.
10911 2001-08-28 Kevin Ryde <user42@zip.com.au>
10913 * doc/autoconf.texi (Function Portability): Mention C right shifts.
10915 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
10917 * lib/autotest/general.m4: Reword some messages.
10918 (AT_INIT): Check for the `times' builtin before using it.
10919 Support test ranges as arguments to the testsuite.
10920 Have -e imply -d as the help text suggested.
10922 2001-08-27 Akim Demaille <akim@epita.fr>
10924 * Makefile.maint: Formatting changes.
10925 (do-po-update, po-update, cvs-update, update): New targets.
10926 (AMTAR): Remove.
10928 2001-08-27 Akim Demaille <akim@epita.fr>
10930 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

10933 <AUTOTEST_PATH>: May contain absolute dir names.
10935 2001-08-27 Akim Demaille <akim@epita.fr>
10937 * lib/autotest/general.m4 (AT_INIT): Log the command line.
10938 Support `VAR=VAL' as arguments.
10939 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
10940 may be set via the command line.
10942 2001-08-27 Akim Demaille <akim@epita.fr>
10944 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
10945 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
10946 first the build dirs, then the src dirs.
10947 * configure.ac (AC_CONFIG_TESTDIR): Adjust.
10949 2001-08-27 Akim Demaille <akim@epita.fr>
10951 * lib/autotest/general.m4 (AT_INIT): Output the definition of
10952 at_data_files earlier.
10953 (--clean, -c): New option.
10954 * tests/Makefile.am: Use this option.
10956 2001-08-27 Akim Demaille <akim@epita.fr>
10958 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
10959 `ac_top_builddir' to mimic Automake's vocabulary, which much more
10960 readable.
10961 Adjust callers.
10962 * doc/autoconf.texi (Configuration Actions): Document the vars
10963 available in commands.
10964 Emphasize the risks of collisions in init-cmds.
10966 2001-08-27 Akim Demaille <akim@epita.fr>
10968 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
10969 (Initializing configure): this new node.
10971 2001-08-27 Akim Demaille <akim@epita.fr>
10973 * Makefile.am (EXTRA_DIST): INSTALL.txt is a dead hack.
10975 2001-08-27 Akim Demaille <akim@epita.fr>

10982 2001-08-27 Akim Demaille <akim@epita.fr>
10984 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move
10985 to...
10986 * lib/autoconf/autoheader.m4: this new file.
10987 * lib/autoconf/general.m4 (AH_OUTPUT, AH_VERBATIM)
10988 (_AH_VERBATIM_OLD, AH_TEMPLATE, _AH_TEMPLATE_OLD, AH_TOP, AH_BOTTOM):
10989 Move to...
10990 * lib/autoconf/autoupdate.m4: this new file.
10992 2001-08-27 Akim Demaille <akim@epita.fr>
10994 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
10995 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
10996 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
10997 -> ac_dir).
10998 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
10999 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
11001 2001-08-27 Akim Demaille <akim@epita.fr>
11003 * lib/autoconf/autoconf.m4 (AC_CONFIG_COMMANDS)

11026 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
11027 (AMTAR): Help automake define it.
11028 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
11029 needed, 1.5 can have a macro and a target with the same name.
11030 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
11031 * m4/strip.m4: New.
11032 * m4/init.m4, m4/sanity.m4: Update.

11044 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
11045 Adjust callers.
11046 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11047 the name of the directory they're in, instead of the filename,
11048 since version.m4 is now in m4sugar, but m4_acversion must not be
11049 classified as an Autoconf macro.
11050 ($input_m4): Don't qualify the path to m4sugar.
11051 Rather, pass autoconf_dir to m4.
11052 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
11053 * tests/suite.at: Require 2.52c.
11055 2001-08-27 Akim Demaille <akim@epita.fr>

11067 of config.log on traps.
11068 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
11069 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
11070 for config.status'.
11071 Open the log as soon as possible.
11072 Use the same log introduction as configure's.
11074 2001-08-22 Paul Eggert <eggert@twinsun.com>
11076 * doc/autoconf.texi (Indices): New node.
11077 Move indices out of the top level menu and into this submenu.
11079 2001-08-22 Akim Demaille <akim@epita.fr>
11081 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11082 AC_TRY_COMMAND.
11083 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
11085 2001-08-22 Akim Demaille <akim@epita.fr>
11087 * lib/autoconf/general.m4 (AC_SHELL_PATH_WALK, AC_CHECK_PROG)

11092 (AC_PROG_RANLIB, AC_PROG_YACC, AC_PROG_LEX, _AC_DECL_YYTEXT)
11093 (AC_PROG_INSTALL, AC_PROG_LN_S, AC_RSH): Move to...
11094 * lib/autoconf/programs.m4: here.
11095 (_AC_DECL_YYTEXT): Rename as...
11096 (_AC_PROG_LEX_YYTEXT_DECL): this.

11114 * lib/autoconf/autoconf.m4, lib/autoconf/Makefile.am: Adjust.
11116 2001-08-22 Akim Demaille <akim@epita.fr>

11124 * configure.ac (AT_CONFIG): Fix the path.
11125 * m4/atconfig.m4 (AT_CONFIG): Don't use EOF but ATEOF so that 2.52
11126 can be used.
11128 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
11130 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
11131 program with AC_LANG_PROGRAM before feeding it to
11132 AC_COMPILE_IFELSE. Cleanup grep usage.
11134 2001-08-20 Akim Demaille <akim@epita.fr>
11136 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
11137 * NEWS, README, README-alpha, TODO, tests/README: This package is
11138 `Autoconf', not `autoconf' (the executable).
11140 2001-08-20 Akim Demaille <akim@epita.fr>
11142 Info readers seem to need `Index' in the index node title :(
11144 * doc/autoconf.texi: Reverse the 2001-08-15 change which
11145 simplified index node names.
11147 2001-08-20 Akim Demaille <akim@epita.fr>

11191 Huh!?!?! There are still some user EOF tags used, which prevents
11192 their use in AC_CONFIG_COMMANDS for instance...
11194 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
11195 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

11258 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

11276 * doc/autoconf.texi: Work around Texinfo buglets.
11277 (Transformation Rules): One example is enough, users are expected
11278 to have their brains on. And BTW, use DESTDIR.
11279 (dvar): New macro. Use it.
11281 2001-08-17 Akim Demaille <akim@epita.fr>
11283 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

11331 (cvs-dist): depends upon it.
11333 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
11335 * tests/Makefile.am: Use a clean-local rule to remove
11336 autom4te.cache (it's a directory, not a file.
11337 * Makefile.am: Ditto (but maintainer-clean-local).
11339 2001-08-15 Akim Demaille <akim@epita.fr>
11341 * bin/autom4te.in (@m4_warning): New.
11342 (&handle_m4): Use it.
11343 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
11344 warnings are issued at each run.
11345 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
11346 is in the src tree.
11348 2001-08-15 Akim Demaille <akim@epita.fr>
11350 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
11351 don't waste time running `autoupdate --version' works.
11352 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
11354 2001-08-13 Akim Demaille <akim@epita.fr>
11356 * doc/autoconf.texi (ma): Rename this index as...

11409 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
11411 * tests/semantics.at (AC_C_BIGENDIAN): New test.
11413 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11415 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
11416 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
11417 * doc/autoconf.texi (C Compiler Characteristics): Update
11418 documentation for AC_C_BIGENDIAN.
11420 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11422 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11423 magic values from an object file when cross-compiling.
11424 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11426 2001-08-10 Akim Demaille <akim@epita.fr>
11428 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11429 effects.
11430 Suggested by Russ Allbery.
11432 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11434 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11435 current $prefix to the sub-configures.
11437 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11439 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
11440 extension (needed on BeOS). Reported by Guido van Rossum.
11442 2001-08-09 Akim Demaille <akim@epita.fr>
11444 * bin/autom4te.in ($icache): Load it only if older than autom4te.
11446 2001-08-07 Akim Demaille <akim@epita.fr>
11448 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11449 removed.
11450 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11451 No need to remove the files before and after the each test, before
11452 each test and at the end of the suite is enough.
11453 Display only the children `times', not the shell's.
11454 If the test failed or was skipped, at-times is not available.
11456 2001-08-07 Akim Demaille <akim@epita.fr>
11458 Always produce testsuite.log, including when there are no
11459 failures. This helps getting information on skipped tests, and
11460 duration of the tests. Err, implement the latter btw.
11462 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
11463 Dump information on the first run of each test.
11464 (AT_CLEANUP): Create `at-times' containing the duration of the
11465 test group.
11467 2001-08-07 Akim Demaille <akim@epita.fr>
11469 The use of `dumpstat' revealed that `len' was used although it
11470 should not. m4_text_wrap was using it, but in the Autoconf world
11471 where it is legal. Hence (i) test M4sh in its own world, not
11472 Autoconf's, and (ii), ahem, fix the bug :)
11474 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11475 does not like `' instead of [].
11476 (AT_INIT): Forbid `^_?AT_'.
11477 And don't output such tokens.
11478 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11479 `script.as', and `autom4te.cache'.
11480 Remove `empty' and `macro' which are no longer used.
11481 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11482 * tests/m4sugar.at: Use it.
11483 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11485 2001-08-07 Akim Demaille <akim@epita.fr>
11487 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
11489 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
11491 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
11493 2001-08-04 Akim Demaille <akim@epita.fr>
11495 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
11496 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
11497 AC_TRY_LINK.
11498 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
11499 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
11500 (AC_F77_MAIN): Likewise.
11502 2001-08-04 Akim Demaille <akim@epita.fr>
11504 Don't rely on M4sugar outputting the patterns in files, since we
11505 might process the output _without_ running m4, hence without these
11506 files.
11508 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
11509 * bin/autom4te.in (@Request::includes): Remove, unused.
11510 (@Request::source): Rename as...
11511 (@Request::input): this.
11512 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
11513 (&handle_output): Fetch the patterns from the traces.
11514 `$forbidden' and `$allowed' are constant: use m//o.
11515 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
11516 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
11518 2001-08-04 Akim Demaille <akim@epita.fr>
11520 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
11521 autoconf', i.e., in addition to caching traces, cache the output.
11523 * bin/autom4te.in (Request::cache): Rename as...
11524 (Request::id): this.
11525 ($cache, $icache, $tcache, $ocache): New.
11526 (&handle_m4): Save M4 output in the cache instead of $tmp.
11527 (&handle_output): Adjust.
11528 (&up_to_date_p): Check that the output cache is up to date too.
11529 (top level): Run `&handle_m4' iff force or the cache is invalid.
11530 Run `&handle_output' if the output cache is more recent.
11532 2001-08-04 Akim Demaille <akim@epita.fr>
11534 * bin/autom4te.in ($force): New.
11535 (&parse_args, &print_usage): -f, --force is a new option.
11536 (&handle_output): CPP directives might have spaces after `#'.
11537 (&parse_args): The first file only can be frozen.
11539 2001-08-04 Akim Demaille <akim@epita.fr>
11541 Don't let autom4te compute the `include' traces several times:
11542 first check that the trace cache file is up to date, and then
11543 compare its timestamp with that of the output.
11545 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
11546 the preamble. Don't require 5.005 as Autom4te::General does it,
11547 and better yet (use `use', not `require'!).
11548 * lib/Autom4te/Struct.pm: Rename the last occurrences of
11549 Class::Struct as Autom4te::Struct.
11550 * lib/Autom4te/General.pm (File::stat): Use it.
11551 (&mtime): New, export it.
11552 * bin/autom4te.in: Use it.
11553 Declare `$req' is invalid if it is outdated.
11554 Don't declare it valid before saving it if something went wrong.
11556 2001-08-04 Akim Demaille <akim@epita.fr>
11558 Autom4te shall not encode Autoconf data, and preselecting traces
11559 must be proposed to the users.
11561 * bin/autom4te.in (@required_trace): Remove.
11562 (@preselect): New.
11563 (&parse_args, &print_usage): -p, --preselect is a new option.
11564 (&up_to_date_p): Adjust.
11565 * bin/autoconf.in: Preselect some Autoconf macros.
11567 2001-08-04 Akim Demaille <akim@epita.fr>
11569 * tests/tools.at (autoconf --trace: user macros): Check traces on
11570 macros invoked without arguments, and macros invoked with multiple
11571 lines arguments.
11573 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
11575 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
11576 arguments.
11578 2001-08-03 Akim Demaille <akim@epita.fr>
11580 * bin/autoconf.in ($@): Work around the usual sh bug.
11581 From Nicolas Joly.
11583 2001-08-03 Akim Demaille <akim@epita.fr>
11585 Clean up the handling of the M4 builtins tracing exception.
11587 * bin/autom4te.in (Request::request): Don't complete M4 builtins
11588 trace requests.

11592 (&parse_args): Complete the trace requests with alternate names.
11593 (&handle_traces): Hence no longer do it here.
11594 (&trace_requests): Remove, unused.
11596 2001-08-03 Akim Demaille <akim@epita.fr>
11598 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
11599 m4_if, and m4_wrap.
11601 2001-08-03 Akim Demaille <akim@epita.fr>
11603 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
11604 (m4_divert_pop): Dump the whole diversion stack when a diversion
11605 mismatch happens.
11606 * bin/autom4te.in (&handle_output): Remember of the first
11607 occurrence of a possibly undefined macro, not the last.
11608 Complain about the possibly undefined macros in the same order as
11609 the appear in the output.
