3 * tests/autotest.at (BSx641-newline in command):
4 (BS-BS-newline in command, BSx640-newline in command):
5 (Newline-CODE-BS-newline in command):
6 (Single-quote-BS-newline in command):
7 (Single-quote-newline-BS-newline in command):
8 Use printf '%s\n' instead of echo, for portability to hosts
9 where echo interprets backslashes. This will break on hosts
10 that lack printf, but for now let's assume all such hosts
11 are dead (if not, we should get reports of test failures).
13 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
15 'echo' has some portability problems, when given a first argument
16 with a leading '-', or when given any argument containing '\'.
17 Avoid using 'echo' in these cases.
18 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
19 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
20 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
21 * lib/autotest/general.m4 (AT_INIT): Likewise.
22 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
23 argument might be unportable.
24 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
25 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
26 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
27 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
28 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
29 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
30 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
31 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
32 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
33 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
34 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):

38 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
39 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
40 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
41 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
42 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
43 * bin/autoconf.as: Redo verbose flag implementation, as the old
44 scheme wouldn't work with AS_ECHO.
45 * lib/autotest/general.m4 (AT_INIT): Likewise.
46 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
47 Don't use ECHO_T, since ECHO_N is now reliable.
48 * lib/autotest/general.m4 (AT_INIT): Likewise.
49 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
50 rather than using a here-document to put the script into a file.
51 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
52 use AS_ECHO.
53 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
54 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
55 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
56 bug, but we might as well stop using ECHO_N and ECHO_C internally.
57 * lib/autotest/general.m4 (AT_SETUP): Likewise.
58 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
59 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
60 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
61 operand, as AS_ECHO requires. Avoid double file name expansion.
62 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
63 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
64 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
65 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
66 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
67 Double-quote strings that would otherwise contain M4 comments.
68 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
70 * configure.ac (AC_INIT): Bump to 2.61a.
71 * NEWS: Likewise.
73 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
75 Version 2.61.
77 * configure.ac (AC_INIT): Bump to 2.61.
78 * NEWS: Likewise.
80 * tests/autotest.at (Macro with backslash in a test title):
81 Comment out for now, as this tests neither fails nor passes
82 reliably. Problem reported by Ralf Wildenhues.
84 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
86 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
87 in previous change, which caused test failures.
89 2006-11-16 Stepan Kasal <kasal@ucw.cz>
91 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
92 code for --enable, --disable, --with, and --without to...
93 (_AC_INIT_PARSE_ENABLE): ... a new macro.
94 * doc/autoconf.texi (Package Options):
95 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
97 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>

134 Import these changes from texinfo via gnulib:
136 2006-11-08 Karl Berry <karl@gnu.org>
138 * build-aux/texinfo.tex (\dopdfimage): look for png, jpg/jpeg/JPG, and
139 as well as pdf images, since they are supported in pdftex with
140 no further ado.
142 2006-11-05 Karl Berry <karl@gnu.org>
144 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.

161 benefit of platforms like Solaris+GCC where it is common to have a
162 non-working g++ installation.

165 and Joel E. Denny <jdenny@ces.clemson.edu>
166 and Paul Eggert <eggert@cs.ucla.edu>
168 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
169 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
170 ./micro-suite.
172 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
174 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
175 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
176 Imported from a similar patch to gnulib by Bruno Haible.
178 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
180 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

187 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Detect bug in
188 Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
189 Matthew Woehlke.

194 Automake 1.10 nor future Automake 11.1 (sic).
196 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
197 and Stepan Kasal <kasal@ucw.cz>
199 Handle special characters in test case titles correctly.
200 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
201 properly.
202 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
203 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
204 argument. Extend to check titles printed by ./micro-suite and
205 ./micro-suite -l and the title in micro-suite.log.
206 (Backquote in a test title,
207 Single-quote in a test title,
208 Double-quote in a test title): Don't expect failure anymore.
209 (Backslash in a test title): Put a non-whitespace character after the
210 backslash so that Bourne shells might actually see it as an escape
211 sequence.
212 (Brackets in a test title,
213 Pound in a test title,
214 Comma in a test title,
215 Quoted Macro in a test title,
216 Macro in a test title,
217 Macro with single-quote in a test title): New tests.
218 (Macro with backquote in a test title,
219 Macro with double-quote in a test title,
220 Macro with backslash in a test title): New tests expected to fail.
221 * tests/torture.at (#define header templates): M4-quote this title in
222 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
223 The visible effect was a stray [] in the testsuite output.
225 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
227 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
228 `trap ... 0' inside a function, for AIX sh.
230 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
232 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
233 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
234 5363) simply issues a warning when dividing by zero at compile
235 time. Problem reported by Elias Pipping.
237 2006-10-26 Eric Blake <ebb9@byu.net>
239 * THANKS: Update.
240 * doc/autoconf.texi (Evaluation Macros): Improve the example to
241 show effect on macros that expand with commas.
242 Reported by Joel E. Denny.

259 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm
260 needs operands on NetBSD 2.0.2. Problem reported by Bruno Haible.
262 2006-10-24 Stepan Kasal <kasal@ucw.cz>
264 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
266 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
268 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
269 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
270 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
271 reported by Nelson H. F. Beebe for Coreutils 6.4.
273 * tests/tools.at (autoconf --trace: user macros): Remove test
274 for tracing multiline macros, since m4 1.4.7a uses a different
275 way to number lines. Problem reported by Ralf Wildenhues.
277 2006-10-24 Stepan Kasal <kasal@ucw.cz>
279 * bin/autom4te.in (handle_m4): Do not redirect stdin to
280 /dev/null since the heuristics for interactive behaviour was
281 fixed in CVS m4.
283 * bin/autom4te.in: With --force, always refresh the output
284 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
286 * bin/autoconf.as: Fix the verbose message at the end.
288 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

299 * build-aux/texinfo.tex: automake 1.10
301 * NEWS: Remove AC_CACHE_CHECK_INT.
302 * doc/autoconf.texi (Caching Results): Likewise.
303 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
304 AC_CACHE_CHECK_INT, since it's no longer public.
305 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
306 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
308 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
310 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
312 2006-10-19 Eric Blake <ebb9@byu.net>
314 * lib/m4sugar/m4sugar.m4 (m4_mkstemp): New macro.
315 (m4_maketemp): Avoid warnings with M4 1.9a.
316 * lib/emacs/autoconf-mode.el (autoconf-font-lock-keywords): Color
317 m4_mkstemp.
318 * doc/autoconf.texi (Redefined M4 Macros): Document m4_mkstemp.
319 * NEWS: Likewise.
321 2006-10-16 Eric Blake <ebb9@byu.net>
323 * doc/autoconf.texi (Setting Output Variables): Fix typo.
325 * bin/autoconf.as (version): Reword to match GNU Coding
326 Standards.
327 * bin/autoheader.in (version): Likewise.
328 * bin/autom4te.in (version): Likewise.
329 * bin/autoreconf.in (version): Likewise.
330 * bin/autoscan.in (version): Likewise.
331 * bin/autoupdate.in (version): Likewise.
332 * bin/ifnames.in (version): Likewise.
334 2006-10-14 Stepan Kasal <kasal@ucw.cz>
336 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
337 looking for special shell characters.
338 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
339 macro defined by AS_VAR_PUSHDEF before passing it as a
340 parameter.
341 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
342 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

351 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
353 (Imported from Automake.)
354 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
355 which incorrectly sets the mode of an existing destination
356 directory. In some cases the unpatched install-sh could do the
357 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
358 system. We hope this is rare in practice, but it's clearly worth
359 fixing. Problem reported by Alex Unleashed in
360 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
361 Also, don't bother to check for -m bugs unless we're using -m;
362 suggested by Stepan Kasal.
364 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
366 Import this change from Automake:
368 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

370 is enabled by default with gnu and gnits strictness.
371 Report from Bruno Haible.
373 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
374 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
375 gnu and gnits modes.
377 Import this change from Config:
379 2006-09-20 Ben Elliston <bje@gnu.org>
380 * build-aux/config.sub (score, score-*): New.
382 Import this change from Gnulib:
384 2006-09-16 Karl Berry <karl@gnu.org>
385 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
386 to avoid sectioning errors.
388 Import these changes from Texinfo:
390 2006-10-04 Karl Berry <karl@gnu.org>
391 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
392 (\quoteexpand): rename to \rquoteexpand.
393 (\codequoteleft): new def, to look for @set codequotebacktick.
394 (\lquoteexpand, \quoteexpand): new defs.
395 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
396 (\code): must use new \...Char values, since now ` is active.
398 2006-08-26 Karl Berry <karl@gnu.org>
399 * build-aux/texinfo.tex (\textdegree): New command.
401 2006-08-12 Karl Berry <karl@gnu.org>
402 * build-aux/texinfo.tex (error \box0): smaller font.
404 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
406 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
408 2006-10-13 Stepan Kasal <kasal@ucw.cz>
410 * doc/autoconf.texi (Autoheader Macros): Warn that the text
411 added to the template can get mangled.
413 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
415 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
416 include the default headers, and redefine obstack_chunk_alloc
417 and obstack_chunk_free. Fixes false failure with glibc.
419 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
421 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
422 for backward compatibility with Libtool 1.5.22. Problem reported
423 by Ralf Wildenhues.
425 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
427 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
428 AC_PROG_CC.
429 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
431 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
433 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
434 the NonStop platform.
435 * doc/autoconf.texi (Posix Variants): Likewise.
436 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
438 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
439 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
440 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
441 Use a better substitute, by inspecting the output of "ls"
442 rather than just using ":".
443 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
444 rather than AS_EXECUTABLE_P, since we needn't worry about
445 non-regular files here.
447 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
448 due to configuration hassles with this. See Tonya Underwood's report
449 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
450 * doc/autoconf.texi (Special Shell Variables): Likewise.
452 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
453 Stepan Kasal <kasal@ucw.cz>
455 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.

461 initialization which is not inherited through the environment
462 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
463 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
465 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
467 * doc/autoconf.texi (Limitations of Usual Tools): Describe
468 problems with mkdir -p -m.
470 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
472 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
473 comment about ac_cpp_err; it was incorrect, and anyway
474 ac_cpp_err is being removed below.
475 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
476 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
477 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
478 nobody uses it.
479 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
480 with werror_flag and conftest.err and so forth. This is more
481 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
482 and anyway the user shouldn't normally want to see this gorp logged.
483 Problem reported by Ralf Wildenhues.
484 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
485 empty, not 'no', since the rest of the code uses 'test -z'.
487 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
489 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
490 Use a single call to AC_DO_TOKENS rather than multiple, for
491 efficiency.
492 (_AC_LINK_IFELSE): Test that resulting file is executable.
493 Problem reported by mwoehlke in
494 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
496 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
497 than creating a file to use with test -x; this is much faster.
499 2006-10-02 Bruno Haible <bruno@clisp.org>
501 * lib/autom4te.in (Automake-preselections): Add
502 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
504 2006-09-27 Stepan Kasal <kasal@ucw.cz>
506 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for

509 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
511 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
512 fseeko testing program twice; just use the earlier result.
513 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
514 Set cache var to 'unknown' (not 'no') if leaving the macro unset
515 still doesn't let the program compile.

517 failed.
519 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.

528 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
529 `error.h', and include it, for a `error_at_line' prototype.
530 Use a nonempty format string in the link test.
531 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
532 for a declaration of wait3.
534 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>

537 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
538 can apply to constants too, and that it checks for macro defns.
539 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
540 and simply cast the identifier to void. This handles structure
541 values. Problem reported by Ralf Wildenhues.

544 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

598 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
599 --error-output, to avoid warnings with M4 2.0.
601 2006-09-19 Stepan Kasal <kasal@ucw.cz>
603 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

630 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
631 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
632 for the existence of the directory at configure-time. That's
633 too late, anyway. Problem reported by Stefan Seefeld.
635 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
636 7.1.4 /usr/bin/posix/sh described by Tim Rice in
637 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
639 2006-09-11 Stepan Kasal <kasal@ucw.cz>
641 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
642 works with GNU M4 1.4.3 again; make the normalized form
643 match the current m4 message; fix the description.

649 to catch glibc bug 2821
650 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
652 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
653 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
654 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
655 assume C89.
657 2006-09-08 Stepan Kasal <kasal@ucw.cz>
659 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

752 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
753 deal with LEXLIB.
754 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
755 didn't work if some values were cached but not others. Test for
756 broken lex libraries like native ia64-hp-hpux11.22; see
757 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
758 work around the problem by preferring an empty LEXLIB to -lfl or
759 -ll. Let the user set LEXLIB='' to indicate no library needed.
761 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
762 * README: Likewise.

928 settings. Report by Bruno Haible.
930 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
932 Fix test suite failures reported by Pierre in
933 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
934 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
935 the compiler created a file "b.out" when it didn't create anything
936 at all.
937 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
938 Discard stderr too, when invoking the test script.
940 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
942 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
943 in the restoring of the werror flag.
945 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
947 * doc/autoconf.texi (Volatile Objects): Be even a little
948 less skeptical about "volatile", after discussion with
949 Bruno Haible on bug-gnulib.
950 (Limitations of Usual Tools): Warn about sed stripping
951 leading white space from text. From Bruno Haible.
953 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
955 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
956 compiler complains about it, even if things works after the
957 complaint. Problem reported by Peter O'Gorman.
959 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
960 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
961 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
963 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
965 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
966 after -R regardless of host. Patrick Welche reports that this
967 fixes things on NetBSD 3.99.
969 * NEWS: Recommend M4 1.4.5.
970 * README: Likewise.
971 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
972 * tests/tools.at (autom4te cache): Update wording of diagnostic
973 to match M4 1.4.5.
975 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
977 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
978 under AC_C_VOLATILE.
979 (Volatile Objects): Be a little less skeptical about what
980 "volatile" means. Derived from thoughts by Ben Pfaff in
981 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
983 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
985 * doc/autoconf.texi: Fix some typos.
987 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
989 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
990 more globally, since the 2006-06-30 patch didn't suffice. Problem
991 reported by Keith Marshall. Also, don't bother with builddir2,
992 since it shouldn't be needed any more.
994 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
996 * doc/autoconf.texi (Generic compiler characteristics):
997 Document AC_COMPUTE_INT. Fix wrong statements on Default
998 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
1000 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
1001 (_AC_COMPUTE_INT): Add obsoletion warnings.
1002 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
1003 AC_COMPUTE_INT.
1005 * NEWS: Document change.
1007 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
1009 * doc/autoconf.texi (Volatile Objects): New section.
1011 * NEWS: Document previous change.
1013 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1015 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1016 Require that long long int be at least 64 bits wide. C99 requires
1017 this and enough programs depend on it so we should check for it.
1018 Bruno Haible reports in
1019 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1020 that long long int is 32 bits wide with some nonstandard compilers.
1021 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1023 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1025 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1026 to a nonexistent file, so that we don't have to worry about
1027 a local site configuration that doesn't use /usr/local.
1028 Problem reported by Keith Marshall in
1029 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1031 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1033 * doc/autoconf.texi: Be more consistent about using @acronym with
1034 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1035 quite right (it talked about "OSF/Tru64", even though the
1036 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1037 and it even mentioned "OSF 4"!) and at this point there's little
1038 reason to talk about OSF any more, since it died in 1994.
1039 (Specific Compiler Characteristics): Simplify example of
1040 negative-size array.
1041 (File Descriptors): Reorder to make the text flow better.
1042 Remove joke about "appreciate the various levels"; I didn't get it.
1043 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1044 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1045 (File Descriptors, Limitations of Usual Tools):
1046 Tone down the advice against renaming or removing open files.
1047 (Limitations of Usual Tools): Add a new section, on 'rm'.
1049 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1051 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1052 -lXt in LIBS, idea from Karsten Hopp; this was due since
1053 this change:
1055 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1056 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1057 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1058 (which belong to Xt, not X itself). See Debian bug 327655.
1060 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1062 * configure.ac (AC_INIT): Bump to 2.60a.
1063 * NEWS: Update.
1065 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1067 Version 2.60.
1069 * configure.ac, NEWS: Update.
1071 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1073 * config/texinfo.tex: Sync from upstream.
1075 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1076 quadrigraph correctly in traces.
1078 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1079 Fix typos.
1081 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1082 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1083 not defined.
1084 * doc/autoconf.texi (Changed Directory Variables): New node,
1085 to document the whole `datarootdir' business a bit better.
1086 * NEWS: Update.
1087 * tests/torture.at (datarootdir workaround): Extend test.
1088 Prompted by report by Alexandre Julliard.
1090 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1092 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1093 when using default mode of IBM C 6 for AIX. Problem and two-line
1094 fix reported by Larry Jones.
1096 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1098 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1099 about literal '${datarootdir}' if a definition is found in the
1100 output file.
1102 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1104 * NEWS: Use "M4" rather than "m4" when appropriate.
1105 Problem reported by Eric Blake.
1106 * doc/autoconf.texi: Likewise.
1107 Use @acronym around BSD, GCC, and GNU when appropriate.
1108 (Why GNU M4): Renamed from "Why GNU m4".
1109 (Redefined M4 Macros): Mention that Posix
1110 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1111 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1112 to int.
1114 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1116 * bin/autom4te.in (handle_output): Do not forbid the empty
1117 pattern.
1118 * tests/tools.at (autoconf: the empty token): New test.
1120 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1122 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1123 calls, so that we do not care whether they are LIFO or FIFO;
1124 in the m4_wrap, do not check which diversion is the topmost
1125 one, just check that the stack is balanced at the end.
1126 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1127 base diversion forever--pop the previous diversion before
1128 opening the new one; consequently, remove the m4_wrap call.
1129 * lib/autotest/general.m4 (AT_INIT): Likewise.
1130 * tests/m4sugar.at: Do not use
1131 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1133 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1134 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1136 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1137 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1138 Rework example of m4wrap token-pasting trouble so that it doesn't
1139 care whether it's LIFO or FIFO.
1140 Fix some "contrary to"s that are awkward in English.
1142 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1144 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1145 to `yes' instead of `int$1_t' if the type is found, for more
1146 consistent configure output (where $1 is the number of bits).
1147 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1148 Suggested by Bruno Haible.
1150 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1151 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1152 with system headers. Report by Bruno Haible.
1154 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1156 * config/config.guess, config/config.sub: Sync from upstream.
1158 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1159 in order to avoid picking up an older installed frozen m4sh.m4f.
1160 Besides an outdated shell startup, this could have been created
1161 by an earlier M4 version with incompatible frozen file format.
1163 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1165 * README: Recommend m4 1.4.4 instead of 1.4.3..
1166 * doc/autoconf.texi: Likewise.
1167 (Special Chars in Names): Say that $(.FOO) is portable, as
1168 suggested by Stepan Kasal.
1169 (Installation Directory Variables, Build Directories):
1170 (Automatic Remaking, Subdirectories, Fortran Compiler):
1171 (Making testsuite Scripts, Defining Directories):
1172 Quote variable usages better.
1173 (Making testsuite Scripts): Add clean-local rule to makefile
1174 snippet, by Eric Blake.
1175 (Installation Directory Variables): Fix table item font.
1176 Reword slightly to clarify. Generalize advice about
1177 not using special characters to include all file-related
1178 vars, not just VPATH.
1179 (Special Chars in Variables): Warn about special characters in
1180 $(srcdir) too.
1181 (Assignments): Clarify default-value example as suggested by
1182 Ralf Wildenhues in
1183 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1184 (Special Shell Variables): Note leading ./ or ../, as suggested
1185 by Eric Blake.
1186 (Limitations of Builtins): Under cd, warn about CDPATH.
1187 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1188 Ralf Wildenhues.
1190 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1192 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1193 `@var', for texi2html.
1194 (Systemology): Some more word wrapping, for DVI output.
1195 (autom4te Invocation): The short option for `--melt' is `-M',
1196 not `-m'.
1198 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1200 * doc/autoconf.texi: More formatting and English tweaks,
1201 many suggested by Ralf Wildenhues.
1202 Reword to avoid "@code{...}'s" and the like, since it's ugly
1203 with Emacs info mode. discontents -> woes.
1204 Put a few "will"s back. time stamp -> timestamp.
1205 side-effect -> side effect.
1207 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1209 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1210 Warn about $@ not persisting. Problem reported by Julien Danjou in
1211 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1212 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1213 Mention other special chars, too.
1215 2006-06-14 Eric Blake <ebb9@byu.net>
1217 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1219 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1221 * doc/autoconf.texi: Some systematic minor improvements, as
1222 follows. Use "makefile" when talking about makefiles
1223 generally (which might be named "makefile" or "Makefile" or even
1224 "foo.mk"), "Makefile" when talking about a specific makefile
1225 called "Makefile". This unclutters the text from weird quotes
1226 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1227 values" rather than "@var{foo}s" and similar constructs containing
1228 "}s". Use "Make rules" rather than "Makefile rules". Minor
1229 English-language improvements. Change the prefix "sub-" to "sub"
1230 and "re-" to "re".
1231 Put blank lines around examples more consistently.
1232 Avoid "rather" and "very" as intensifiers.
1233 Avoid "will" as an auxiliary.
1234 (Limitations of Make): Split this node into....
1235 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1236 (Leading _ in Macro Names, Backslash-Newline-Newline):
1237 (Backslash-Newline Comments, Long Lines in Makefiles):
1238 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1239 (obj/ and Make, make -k Status, VPATH and Make):
1240 (VPATH and Double-colon, $< in Explicit Rules):
1241 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1242 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1243 New nodes, resulting from splitup of Limitations of Make.
1244 All cross-references changed. Raise the top node from
1245 a section to a chapter, and all subnodes accordingly.
1246 Redo the introductory wording to match the new organization.
1247 (Installation Directory Variables): Use an example that is
1248 closer to what Autoconf actually does. Mention that VPATH's
1249 value should not contain metacharacters or white space.
1250 (Fortran Compiler): Fix a VPATH bug in an example.
1251 (Leading _ in Macro Names): Mention that this problem is no longer
1252 of practical concern.
1253 (VPATH and Make): Reword the advice to make it clearer
1254 that Autoconf and Automake support VPATH in non-GNU make, but
1255 many packages have bugs in this area.
1256 ($< in Explicit Rules): Refer to Build Directories rather
1257 than using a (non-VPATH-safe) example.
1258 (Automatic Rule Rewriting): Mention the sort of disaster that
1259 can ensue with Solaris-style rule rewriting with VPATH.
1261 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1263 * doc/install.texi (Compilers and Options): Weaken the
1264 suggestion to use GNU make for VPATH builds.
1266 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1267 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1269 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1270 in regular expression.
1272 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1274 * doc/autoconf.texi (Installation Directory Variables):
1275 Drop extra @samp from `@table @samp' item.
1276 (Limitations of Usual Tools): Comment fix.
1277 Do not nest @samp just to point to other table items.
1278 (Writing testsuite.at) <AT_CHECK>: The second argument to
1279 `@dvar' is already @samp'ed.
1280 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1281 do not use @var in the second argument.
1283 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1285 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1286 $as_shell.exe too. Problem reported by Andreas Buening in
1287 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1289 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1291 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1292 `unused variable' compiler warning, for `-Wall -Werror'.
1293 Reported by Jaap Haitsma in
1294 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1296 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1298 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1299 case the compiler dumps core. Problem reported for
1300 OpenServer 5.0.7 by Tim Rice in
1301 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1302 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1303 Likewise.
1305 2006-06-06 Tim Rice <tim@multitalents.net>.
1307 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1308 "ERROR" only shows up in "make check" output if there is an
1309 error.
1311 2006-06-06 Eric Blake <ebb9@byu.net>
1313 * tests/tools.at (automatically allowed tokens): Fix typo.
1315 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1317 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1319 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1320 typically overflows on x86 CPUs, even though the C standard
1321 requires otherwise.
1323 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1325 * configure.ac (AC_INIT): Bump to 2.59e.
1326 * NEWS: Update.
1328 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1330 Version 2.59d.
1332 * config/texinfo.tex: Sync from upstream.
1334 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1335 seen, invoke libtoolize with `--ltdl' argument.
1336 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1337 * NEWS: Update.
1338 Suggested by Eric Blake.
1340 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1342 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem

1360 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1361 to...
1362 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1363 AT_CHECK_M4.
1364 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1365 `expout' as the last parameter.
1366 * tests/tools.at: Adapt to the above change.
1368 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1370 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1371 information about race-free implementations of mkdir.
1373 2006-06-04 Eric Blake <ebb9@byu.net>
1375 * bin/autoreconf.in (help): Document M4 environment variable.

1382 * NEWS: GNU make now recommended for VPATH builds.
1383 Mention that some macros are now documented to be obsolescent.
1384 * doc/autoconf.texi:
1385 Prefer "current" to "modern" to describe
1386 currently-used (albeit perhaps old-fashioned) hosts.
1387 Mention which ancient features no longer need to be worried about.
1388 setgid -> set-group-ID
1389 setuid -> set-user-ID (these are the Posix terms)
1390 Fix some misuses of "only".

1398 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1399 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1400 Mention that these macros are obsolescent.
1401 (Installation Directory Variables): shall -> should
1402 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1403 Mention that it's now safe to use 3 and 4.
1404 (Limitations of Usual Tools): cp -r is now specified by Posix.
1405 Omit longwinded and obsolescent discussion of cp -f.
1406 Modernize discussion of expr, ls.
1407 (Limitations of Make): Modernize discussion of VPATH builds.
1408 Mention $? as a workaround in some cases.
1409 * doc/install.texi (Basic Installation):
1410 Mention "./configure; make; make install" first. Be more
1411 specific about why this file is generic. Remove unnecessary
1412 parens. Remove misleading "only". Remove obsolete advice
1413 about csh. Don't say "configure" takes awhile; say it
1414 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1415 and CC=c99 rather than CC=c89, as these are blessed by current
1416 Posix. Recommend GNU make if doing a VPATH build.
1418 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1420 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1421 examples involving shell prompts.
1423 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1424 and Paul Eggert <eggert@cs.ucla.edu>
1426 * doc/autoconf.texi (Here-Documents): Add details about the
1427 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1428 use "here-documents" instead of "here documents".
1430 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1432 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1434 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1436 * doc/autoconf.texi (File System Conventions): Warn about ":"
1437 anywhere in directory names.
1439 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1441 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1442 about quoting the case statement, just in case.
1443 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1444 was fixed in ksh93g; reported by Ralf Wildenhues.
1446 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1448 * doc/autoconf.texi (System Services): Do not document
1449 overriding EXEEXT via ac_cv_exeext=ext.
1450 (Particular Programs) <AC_PROG_MKDIR_P>:
1451 Document that ${MKDIR_P} understands --.
1452 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1453 comment.
1455 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1457 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1458 argument with leading hyphen. Problem reported by Paul Eggert.
1460 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1462 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1463 about quoting ac_try: quote all of it, if any of it seems suspicious.
1464 This means we don't have to worry about ${ or sed any more.
1465 Also, double-quote the case statement, to work around misuses via
1466 underquoting as reported by Ralf Wildenhues in
1467 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1468 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1469 undocumented and dangerous macro.
1470 Problem reported by Ralf Wildenhues in
1471 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1473 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1475 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1476 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1477 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1479 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1481 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1482 since evidently some packages rely on the old, broken behavior.
1483 Problem reported by Ralf Wildenhues in
1484 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1485 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1486 pre-2006-05-26 definitions, but leave in the comments that
1487 these macros are dangerous and should not be used.
1488 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1489 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1490 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1491 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1492 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1494 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1496 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1497 the use of 'tr', since this is our only use of 'tr'.
1499 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1500 and Paul Eggert <eggert@cs.ucla.edu>
1502 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1503 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1505 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1507 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1508 the output file in the `${datarootdir}' test.
1510 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1511 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1513 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1514 mention of `datarootdir' in the input file(s), but literal
1515 `${datarootdir}' in the output file, and we haven't warned yet,
1516 then warn as well: the user may have (erroneously) used
1517 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1518 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1519 * tests/torture.at (datarootdir workaround): Extend this test.
1520 * NEWS: Update.
1522 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1523 and Paul Eggert <eggert@cs.ucla.edu>
1525 * doc/autoconf.texi (autoheader Invocation): The first argument to
1526 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1527 alternatives and clear up the language a bit.
1529 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1531 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1532 ac_config_guess, ac_config_sub, ac_configure.
1533 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1534 Fix typo that prevented an unnecessary space from being removed.
1535 Problems reported by Ralf Wildenhues in:
1536 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1538 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1540 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1541 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
1542 Don't use the term "thread-safe" to talk about mkdir race
1543 conditions, since the problem is more a process than a thread
1544 issue. Problem reported by Stepan Kasal in:
1545 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
1546 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
1547 the test for 'install' more closely. Look at MKDIR_P first.
1548 Look in the PATH, and at /opt/sfw/bin.
1549 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1550 Don't bother to try mkdir -p, since we already check mkdir --version;
1551 just look at the version number. (There's no easy way to check
1552 for race-free implementations.)
1553 * tests/tools.at (autoconf: subdirectories): Adjust to above
1554 changes, since MKDIR_P now might end in "/mkdir -p".
1556 * doc/autoconf.texi (autoheader Invocation): Mention that the
1557 first arg of AC_DEFINE_UNQUOTED must be a literal.
1558 Problem reported by Ben Pfaff in
1559 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1561 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1562 * doc/autoconf.texi (Special Chars in Variables): New section.
1563 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1564 (Installation Directory Variables): Quote $(datadir) better.
1565 (Limitations of Builtins): Describe some of eval's trickiness.
1567 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1568 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1569 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1570 in front of every arg, not just trailing args. Quote apostrophes.
1571 (_AC_EVAL_ECHO): New macro.
1572 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1573 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1574 removed.
1575 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1576 exposed by quoting of eval argument. Put the command on line line
1577 so it logs better.
1578 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1579 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1580 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1581 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1582 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1583 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1584 Use eval more safely.
1585 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1586 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1587 to be replaced.
1588 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1589 lines, exposed by quoting of eval argument.
1591 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1592 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1594 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1595 initialization of `ac_cv_exeext', do not override it if it was
1596 already set, unless it was set to `no', for compatibility with
1597 Autoconf-2.13, and comment this.
1598 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1599 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1600 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1601 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1602 Document that this test may be overridden by setting
1603 `ac_cv_exeext'.
1605 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1607 Revert these two patches:
1609 2006-04-06 Eric Blake <ebb9@byu.net>
1610 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1611 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1612 2006-04-01.
1614 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1615 Clean up _AC_COMPILER_EXEEXT* macros.
1616 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1617 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1618 ac_file to the name of the default output file and call
1619 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1620 initial `rm' of the candidate files...
1621 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1622 the same list in subsequent `rm' calls, and for the temporary
1623 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1624 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1625 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1626 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1627 no longer needed) by libtool. Make it a cache check.
1628 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1629 copied here by mistake.
1630 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1631 _AC_COMPILER_EXEEXT.
1632 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1633 _AC_COMPILER_OBJEXT directly.
1634 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1636 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1638 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1639 Fix description of how the buggy `sed' works.
1641 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1643 Sync from Automake:
1645 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1646 ENOLCK. Only mention `make -j' when applicable. Only raise
1647 fatal errors when `make -j' is involved. Improve error message.
1649 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1651 * doc/autoconf.texi (Here-Documents): We now know more about
1652 the variable expansion in here documents bug.
1653 Thanks to Tim Rice and Stepan Kasal.
1655 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1656 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1658 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1660 * tests/autotest.at (Multiline command from M4 expansion):
1661 No failure to be expected if the shell quotes newlines in
1662 commands in the `set -x' output. Report by Tim Rice.
1663 * THANKS: Update.
1665 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1667 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1668 expansion in the here-documents used by config.status, as that
1669 runs afoul of the Korn shell version M-12/28/93d bug described in
1670 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1671 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1672 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1674 2006-05-23 Jim Meyering <jim@meyering.net>
1676 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1677 Fix typo introduced with 2006-04-02 change. It reversed the sense
1678 of the test.
1680 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1682 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1683 ac_dB slightly, to save bytes in the script.
1684 Max out at 50 lines, rather than 96; this is more likely
1685 (though not guaranteed) to avoid obscure 'sed' failures.
1687 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1689 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
1690 `tr -d -' as bad option argument. Work around this by deleting
1691 an unrelated character.
1692 Report by Tim Rice <tim@multitalents.net>.
1694 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
1695 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1696 Stepan Kasal <kasal@ucw.cz>
1698 * doc/autoconf.texi (Particular Programs): Do not promise that
1699 we always prefer the GNU version of the program, and that we
1700 search according to PATH; both rules can have exceptions.
1701 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
1702 AC_PROG_SED. Move descriptions of limitations
1703 to the Limitations of Usual Tools section.
1704 (Limitations of Usual Tools) <sed>: Mention script length
1705 limitations with Solaris /usr/ucb/sed.
1706 <grep>: Fix wording for empty alternative. Mention that -c and
1707 -l should not be combined, and that -E and -F should not be
1708 combined.
1710 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1711 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1713 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
1714 limits in Solaris 8 /usr/ucb/sed by testing a long script.
1716 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1718 * doc/autoconf.texi (Defining Symbols): Literal parameter of
1719 AC_DEFINE is now passed to m4_pattern_allow.
1720 * NEWS: Mention that; likewise for AC_SUBST.
1721 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
1722 the parameter to m4_pattern_allow.
1723 * tests/tools.at: Add a check for that.
1725 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1727 * lib/autoconf/status.m4: Fix typos.
1729 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1731 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1732 only the files that this macro generates.
1734 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1736 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1737 the HP-UX sed limitation of 99 commands, labels do not count.
1738 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1739 in the comment.
1740 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1742 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1744 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1745 Import the following fix from coreutils:
1747 2006-01-13 Jim Meyering <jim@meyering.net>
1749 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1750 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1751 not double-quote uses of that variable, to accommodate the rare
1752 case in which getmntent is available in none of the libraries
1753 checked. This happens at least on FreeBSD 5.0.
1755 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1757 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
1758 ac_config_guess, ac_config_sub, and ac_configure, since evidently
1759 some other programs unwisely rely on these undocumented vars.
1760 But put in warning comments about them.
1761 Problem reported by Ralf Wildenhues in
1762 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
1763 * NEWS: Document that these variables are intended to go away.
1765 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1767 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
1768 and set the language to C++ (analogous to the equivalent Fortran
1769 tests).
1771 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
1772 * doc/autoconf.texi (C++ Compiler): Document it.
1773 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
1774 * NEWS: Update.
1776 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1778 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
1779 that caused config.status to generate 100-command sed scripts; the
1780 portable limit is 99.
1782 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1784 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
1785 variable `ac_d' instead of `d' to avoid infringing namespace.
1786 Report by Ralf Menzel.
1788 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
1790 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
1791 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
1792 * tests/tools.at (autoconf: subdirectories): New test, taken from
1793 the corresponding problem report by Ralf Wildenhues in:
1794 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
1796 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
1797 Quote some uses of shell variables if they might suffer unexpected
1798 globbing. This doesn't fix all instances of quoting problems that
1799 I found, just the easy ones that look safe.
1800 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
1801 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
1802 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
1803 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
1804 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
1805 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
1806 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
1807 Likewise.
1808 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
1809 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
1811 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1813 * bin/autoreconf.in ($help): Reword according to the manual.
1814 Suggested by Olly Betts.
1816 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
1817 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1819 * bin/autoreconf.in: Pass the directory argument to
1820 `require_configure_ac'. Fix comment.
1821 * tests/torture.at (Configuring subdirectories): Expose this.
1822 Reported by Olly Betts.
1824 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1826 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
1827 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
1828 Automake as follows:
1830 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
1831 `$configure_in' instead of `configure.in', to preserve
1832 directory component.
1834 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1836 * config/config.guess, config/config.sub, config/texinfo.tex,
1837 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
1839 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1841 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
1842 test for C99 conformance; (bool) 0.5 is an integer constant
1843 expression, but (bool) -0.5 is not. Problem reported by Fedor
1844 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
1846 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1848 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
1849 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
1850 Warn about obsolete install-sh files. Remove stray sentence
1851 fragment and fix cross reference.
1852 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
1853 install -d; this undoes the 2006-05-10 change.
1854 (MKDIR_P): Mark with AN_MAKEVAR.
1855 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
1856 that we don't require $INSTALL to be thread-safe. Move comments
1857 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
1858 of AC_PROG_INSTALL. Output a message saying that we're checking
1859 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
1860 MKDIR_P instead of AC_SUBST.
1861 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
1862 Special magic for MKDIR_P, too.
1863 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
1864 a dnl.
1865 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
1867 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1869 Sync from Automake, as follows:
1871 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1872 * config/install-sh: Initialize IFS, so field splitting isn't
1873 turned off later.
1874 * config/mkinstalldirs: Likewise.
1875 * config/missing: Remove superfluous quotes. Replace all uses of
1876 `[' by `test', for consistency, and for..
1877 * config/missing (sed_minuso, sed_output): New variables.
1878 (autom4te, help2man, makeinfo): Use them. Unifies detection of
1879 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
1880 Fixes `missing' to detect `--output' for help2man. Fixes
1881 PR automake/483. Report by Dennis J. Linse.
1882 (autom4te): Document in `missing --help'.
1884 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1886 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1887 * config/install-sh: Don't use 'path' to talk about file names,
1888 as per GNU coding standards. Close a race condition reported by Ralf
1889 Wildenhues and Stepan Kasal. There is still a race condition
1890 on hosts that predate Posix 1003.1-1992, but we can't help this.
1891 Don't mishandle weird characters like space on pre-Posix hosts.
1892 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1893 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1894 AC_PROG_MKDIR_P from AS_MKDIR_P.
1895 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1896 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1897 earlier editions are not (including Automake 1.8.3).
1898 Do not suggest mkinstalldirs for thread-safety.
1899 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1900 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1901 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1902 presence of special characters and race conditions.
1903 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
1904 in Autoconf's name space.
1906 2006-05-10 Bruno Haible <bruno@clisp.org>
1907 and Paul Eggert <eggert@cs.ucla.edu>
1909 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
1910 from Automake with minor changes.
1911 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
1913 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1915 * config/install-sh: Update to Automake CVS version, as follows:
1916 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1917 * lib/install-sh: Simplify the expr implementation of dirname.
1918 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
1919 * lib/install-sh: Handle --, and diagnose unknown options.
1921 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1923 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
1924 `./autom4te' to create `./testsuite', since the `all' target
1925 will ensure its presence, but `installcheck' should not create
1926 the uninstalled wrappers.
1928 * tests/torture.at (Unusual Automake input files): Skip if we
1929 detect automake < 1.8.
1931 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1933 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
1934 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
1935 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
1936 * NEWS: Update.
1938 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1940 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1941 munge (multiple) white space and other oddities.
1942 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1943 single quotes in variable assignment.
1944 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1945 and similar failures by adding multiple spaces, tabs, and other
1946 special characters.
1947 Report and different test suggested by Francesco Romani
1948 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1950 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1951 single quotes, we only need to search for single quotes; this
1952 both simplifies the search pattern, and makes us less
1953 susceptible to `echo' variations for arguments not containing
1954 single quotes.
1955 (_AC_ARG_VAR_VALIDATE): Likewise.
1957 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1959 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1960 `$*' and IFS concatenation issue with traditional shells and
1961 bash-2.04. Report by Seanster@Seanster.com.
1963 2006-05-03 Bruno Haible <bruno@clisp.org>
1965 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1966 precisely which Mac OS X versions have the od problem.
1968 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1970 * doc/autoconf.texi: Use @option systematically.
1972 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1973 and Bruno Haible <bruno@clisp.org>
1975 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1976 about 'od'.
1977 (Integer Overflow): Mention the special case of integer division
1978 overflow.
1980 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1982 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1983 traditional shells like the Solaris one that do not use the
1984 first IFS character for assembling `$*'.
1985 Prompted by a related report from autoconf_bug@nro.ca.
1987 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1988 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1990 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1991 Mention more problems with the -e option.
1993 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1995 * NEWS: Typo.
1996 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1998 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1999 in URLs to improve DVI formatted output (requires texinfo 4.6).
2000 (System Services, Systemology, Shellology): Likewise.
2001 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2002 output.
2004 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2005 continuous text.
2006 (Runtime): Fix macro argument names to match description:
2007 `action-if-found' -> `action-if-true' and similarly.
2008 (Obsolete Macros): Likewise.
2009 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2010 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2011 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2013 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2015 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2017 * ChangeLog: Typo.
2018 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2019 DVI output.
2021 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2023 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
2024 /bin/sh set unsorted output.
2025 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
2026 * tests/local.at: Likewise.
2028 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2030 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2031 (Integer Overflow, Null Pointers, Buffer Overruns):
2032 (Floating Point Portability, Exiting Portably): New sections.
2033 (Writing Test Programs): Fix some langauge. Recommend exiting
2034 with status 1, not merely nonzero. Clarify exit declaration.
2035 (Run Time): Move C exit status stuff to new Exiting Portably section.
2036 (Systemology): Mention Posix and levenez. Update v7 reference.
2037 (Portable Shell): Mention the Posix shell.
2039 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2041 * bin/autoconf.as (me): Replace by as_me.
2043 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2045 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2046 since as_me isn't set yet.
2048 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2050 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2051 a few minor bugs in this area.
2053 * doc/autoconf.texi (Programming in M4sh): Comment out the
2054 documentation of AS_BASENAME, for now.
2055 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2056 (Limitations of Builtins) <basename>: Do not refer to
2057 AS_BASENAME.
2058 * bin/autoconf.as (me): Don't use AS_BASENAME.
2059 (dir): Remove the unused variable.
2060 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2061 AS_DETECT_REQUIRED. All uses changed.
2062 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
2063 All uses changed.
2064 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
2065 (AS_BASENAME): Use "basename --" to protect against leading "-".
2066 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2067 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2068 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2069 (_AS_DIRNAME_PREPARE): Likewise.
2070 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2071 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2072 (AS_DIRNAME): Use "dirname --".
2074 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2076 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2077 of "run time" and "run-time" changed to "runtime", for consistency.
2078 * lib/autoconf/fortran.m4: Likewise (in comment).
2079 * lib/autoconf/functions.m4: Likewise.
2080 * lib/autoconf/general.m4: Likewise.
2081 * lib/autoconf/headers.m4: Likewise.
2083 * doc/autoconf.texi (Run Time): Document the exit status situation
2084 with more accuracy and detail.
2086 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2088 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2089 Archive is not officially `GNU' any more. Update URL.
2090 (Defining Directories): Likewise
2091 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2093 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2095 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2096 newline from the `trap' code to finish `config.log'; the NetBSD
2097 /bin/sh resets the exit status after an empty command, as
2098 documented in doc/autoconf.texi.
2099 Reported by Dalibor Topic <robilad@kaffe.org>.
2101 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2103 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2104 Suggested by Bruno Haible.
2106 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2108 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2109 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2110 Instead, just list the shells that we know work.
2111 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2112 changed. Be more cautious about the _cv_ variable.
2113 * tests/tools.at (Syntax of the shell scripts): Check the
2114 _cv_ variable once, at first, to avoid an internal autoconf error
2115 when sh -n does not work.
2117 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2119 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2121 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2123 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2124 use ">&-" since we're only 99.999% sure that this is portable,
2125 and since the MinGW bug is fixed in a different way.
2126 * lib/autotest/general.m4 (AT_INIT): Likewise.
2128 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2130 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2131 before opening config.log, to avoid hitting a bug on MinGW.
2133 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2135 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2136 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2137 This works around a MinGW bug reported by Eric Paire.
2138 Make sure that all writes to the log file append to it,
2139 rather than possibly losing data.
2140 * lib/autotest/general.m4 (AT_INIT): Likewise.
2142 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2144 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2145 description.
2147 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2149 * NEWS: Update.
2151 * configure.ac (AC_INIT): Bump to 2.59d.
2153 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2155 Version 2.59c.
2157 * Makefile.maint (news-date-check): Do not require a leading `*'
2158 before the release date in NEWS.
2160 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2161 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2163 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2164 the instantiated file do not contain the string 'datarootdir'
2165 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2166 @mandir@, replace the reference '${datarootdir}' by the value.
2167 * tests/torture.at (datarootdir workaround): New test.
2168 * NEWS: Advertise this temporary fixup.
2169 Based on a patch by Bruno Haible, reported and analyzed by
2170 Paul Eggert and Noah Misch.
2172 2006-04-12 Eric Blake <ebb9@byu.net>
2174 * tests/autotest.at (Debugging a failed test): Fix comment.
2176 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2178 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2179 all the changes since 2006-04-07.
2181 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2183 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2184 succeeded, but `ln -s file dir' failed, take care to remove the
2185 leftover target before the next test, to prevent its spurious
2186 failure; also make sure `ln file dir' works before selecting it.
2187 Thanks to Keith Marshall for pointing this out.
2188 * THANKS: Update.
2190 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2191 assignments in `at_debug_args', so that we put them correctly
2192 in the `run' script.
2193 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2194 Reported by Eric Blake.
2196 2006-04-11 Eric Blake <ebb9@byu.net>
2198 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2199 top-level tests after micro-suite has been run. Used in...
2200 (Debugging a successful test, Debugging script and environment),
2201 (Debugging a failed test): ...these new tests. The first of these
2202 is fixed by...
2203 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2204 macro, split out from...
2205 (AT_INIT): ...here, so that using -d also generates a run script.
2206 Document that -d inhibits top-level logging.
2207 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2208 inhibits top-level logging; debug scripts are created.
2210 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2211 check.
2212 * tests/autotest.at (Empty test, Empty check): New test to check it.
2214 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2215 from gcc.
2217 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2219 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2220 the files if a problem appears. Make the empty *.at files
2221 read-only, too. Proposed by Ralf Wildenhues.
2223 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2225 * config/Makefile.am: Add comment to force updated Makefile.in.
2227 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2228 space only patch to this file, this patch causes the Makefile.in
2229 files that include freeze.mk to be updated, and thus have a
2230 newer time stamp again, which in turn makes a pristine CVS
2231 checkout have correct time stamps.
2233 * Makefile.maint (cvs-sv): New macro, to be used..
2234 (config.guess-url_prefix, config.sub-url_prefix)
2235 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2236 point to CVS text checkout of Gnulib files.
2237 (copyright-check): Bump current year.
2238 (announcement): Do not hard-wire `./announce-gen'.
2239 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2240 correctly.
2241 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2242 `chmod +x'.
2243 (wget_files): Update config.guess, config.sub, texinfo.tex by
2244 `wget-update', now that their URLs work again.
2246 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2248 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2249 Problem noted by Paul D. Smith.
2251 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2253 * doc/autoconf.texi: Remove unused words from word list.
2254 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2255 .x-sc_trailing_space: New files.
2257 * doc/standards.texi: Sync from gnulib.
2259 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2260 `LIBOBJDIR' as experimental.
2262 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2263 with a target directory; it's internally implemented as `cp'
2264 anyway, but since Autoconf advertises the possibility to use
2265 a target directory when LN_S is `ln -s', we need to find out.
2266 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2267 analyzed by Keith Marshall <keith.marshall@total.com>.
2269 * THANKS: Update.
2271 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2273 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2274 confdefs.h as-is. In general, if it has backslash-newline or the
2275 like, then it doesn't work either to sort or to remove empty
2276 lines.

2280 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.

2287 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2289 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2290 apostrophe within a single-quoted string, as this is the usual
2291 tradition and is easier to read than '"'"'. Don't rely on the
2292 shell treating "$/" like '$/'. Use a more-consistent indenting
2293 style for the trap.
2295 2006-04-09 Eric Blake <ebb9@byu.net>
2297 * tests/autotest.at (Backquote command substitution),
2298 (Multiline backquote command substitution): Remove mistaken
2299 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2300 applied...
2301 (Parenthetical command substitution, Multiline parenthetical
2302 command substitution): here.
2304 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

2334 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2335 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2336 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2337 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2338 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2339 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2340 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2341 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2342 (Coding Style). Don't mention m4_expand_once.

2361 New macros.
2363 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
2364 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
2366 2006-04-08 Stepan Kasal <kasal@ucw.cz>
2368 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
2369 of the warning introduced by the 2001-08-28 change.

2379 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2381 Revert the patch from 2006-04-01 and only improve
2382 _AS_DETECT_BETTER_SHELL:
2384 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2385 skip nonexistent directories.
2386 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2387 only shell candidates which exist.
2388 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2389 * lib/autotest/general.m4 (AT_INIT): No need to give three
2390 parameters to _AS_PATH_WALK.
2392 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2393 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2395 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2396 distinguish m4sugar macros.
2397 * tests/tools.at (autoupdating with aclocal and m4_include):
2398 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2399 test case by Noah Misch <noah@cs.caltech.edu>.
2401 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2403 Revert my change from 2006-03-17, in other words:
2404 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2405 and DUALCASE=1.
2406 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2407 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2408 it is set.
2410 2006-04-07 Eric Blake <ebb9@byu.net>
2412 * doc/autoconf.texi (Programming in M4sh): Document that
2413 AS_MKDIR_P exits the script on failure.
2414 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2416 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2418 * config/elisp-comp, config/install-sh, config/mdate-sh,
2419 config/missing, config/mkinstalldirs: Sync from Automake.
2421 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
2422 from Automake.
2424 * doc/make-stds.texi: Sync from gnulib.

2433 Eric Blake <ebb9@byu.net>,
2434 Paul Eggert <eggert@cs.ucla.edu>,
2435 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2437 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2438 whether `set' quotes correctly: redirect stderr of the tested
2439 `set', and use a subshell, for Ultrix; use `sed' instead of
2440 `grep' for zsh `set' which may write binary output; match only
2441 at the beginning of a line, to avoid false positives.
2442 In order to avoid false positives by unrelated variables with
2443 multiline content, put the dump algorithm in a subshell and
2444 unset all variables containing newlines (except some which are
2445 special to the shell). Warn about cache variables that are
2446 unset.
2448 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2450 * config/config.guess, config/config.sub, config/texinfo.tex:

2459 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
2460 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
2461 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
2462 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
2464 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
2465 shell issue with double-quoted command substitutions of native
2466 commands.
2467 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
2468 Marshall.
2470 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

2485 2006-04-06 Stepan Kasal <kasal@ucw.cz>
2487 * tests/Makefile.am (maintainer-check-posix):
2488 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
2490 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
2491 ac_config_<foo>s again, sometimes normalized, sometimes not.
2492 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
2493 (AC_CONFIG_COMMANDS): Do not do so here.
2494 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
2495 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
2496 2005-07-25 rewrite. Noticed by Noah Misch.
2498 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
2499 _AC_PRESERVE_HELP_ORDER, ...
2500 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
2502 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
2503 inside m4_expand_once; it is redundant.
2505 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
2506 for --help from Cygnus `configure.'
2508 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
2510 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
2511 on a patch proposed by Ralf Wildenhues.

2515 * lib/autoconf/status.m4: Replace <space>''<tab> with
2516 <tab><space> where this makes sense.
2518 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
2519 Noah Misch <noah@cs.caltech.edu>
2521 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
2522 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
2523 * doc/autoconf.texi (Help Formatting): New node.
2524 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
2526 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2528 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,

2538 2006-04-05 Eric Blake <ebb9@byu.net>
2540 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
2541 empty test suite works.
2542 * tests/autotest.at (Empty test suite): Remove xfail.
2544 2006-04-05 Noah Misch <noah@cs.caltech.edu>

2547 TAGS to ac_config_<foo>s.
2548 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
2549 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
2550 normalizing it, consistent it with previous releases.
2551 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
2553 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2555 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
2556 Use simplified args that Eric Blake originally suggested.
2558 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
2560 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
2561 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
2562 Use 'comm' rather than N instances of grep; this also fixes a bug
2563 whereby substrings were incorrectly matched, causing us to not
2564 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
2565 (exclude_list): Exclude empty macros.
2566 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

2571 Switch from grep to awk syntax.
2572 (ac_exclude_script): Renamed from ac_exclude_egrep.

2577 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
2578 a subdirectory subject to Cygnus `configure'.
2579 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
2581 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
2582 report request when we have no AC_PACKAGE_BUGREPORT.
2584 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2586 * THANKS: Update.

2608 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.
2610 2006-04-03 Eric Blake <ebb9@byu.net>
2612 * THANKS: Add myself.
2614 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2616 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
2617 to log, point to testsuite output tree.
2619 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>

2647 Clean up _AC_COMPILER_EXEEXT* macros.
2649 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2650 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2651 ac_file to the name of the default output file and call
2652 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2653 initial `rm' of the candidate files...
2654 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2655 the same list in subsequent `rm' calls, and for the temporary
2656 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2657 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2658 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2659 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2660 no longer needed) by libtool. Make it a cache check.
2661 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2662 copied here by mistake.
2663 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2664 _AC_COMPILER_EXEEXT.
2665 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

2700 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
2701 subordinate tools.

3438 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
3439 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
3440 by the function rather than ignoring it.
3441 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
3442 comparing its address. Intel's interprocedural optimization was
3443 outsmarting the old heuristic. Problem reported by

3460 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3461 Stepan Kasal <kasal@ucw.cz>
3463 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3464 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3465 make its content writable before removing it. Remove an errorneous
3466 comment from the end, where the logs of the failed tests are copied
3467 to the main log file.
3469 2005-09-27 Stepan Kasal <kasal@ucw.cz>
3471 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,

3476 problems if the testsuite were running too fast.
3478 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3480 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h

3492 suggested by Ben Elliston. Handle weird characters correctly.
3494 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3496 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3497 calls, so that the final expansion of this macro is shorter.
3498 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3499 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3500 the cleanup there. Use AS_VAR_* macros, to be more general.
3501 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3503 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3505 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

3520 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3521 The previous patch didn't work, so try a better one.
3523 2005-08-26 Stepan Kasal <kasal@ucw.cz>
3525 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3526 in the example. Reported by Bruno Haible.
3527 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3528 "if $undefined_var;" succeeds with my shell.
3530 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
3531 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
3532 but change the m4_divert_text to m4_divert_once.

3536 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):

3540 2005-08-24 Stepan Kasal <kasal@ucw.cz>
3542 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
3543 some evil values and relying on the fact that $* concatenates the
3544 parameters by the first character from IFS.
3546 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3547 Stepan Kasal <kasal@ucw.cz>
3549 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
3550 first header appears, define AH_HEADER.
3551 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
3552 Update limitations about when to call AC_CONFIG_HEADERS.
3553 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3554 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3555 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3556 ``Configuration Actions''; fix their index entries.
3558 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3559 options correctly. Process N-M as M-N if M is smaller than N.
3560 Process ranges correctly so that N-N will run only N.
3561 Sort and uniquify the tests that will be run. If there is more
3562 than one test, reinsert the banners for the tests.

3568 before passing the macro name to AH_TEMPLATE.
3570 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3571 now opens log after option processing; in particular, --version
3572 and --help do not touch config.log.

3589 Prepend to LIBS, not append, in examples.
3591 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3593 When building in place, set srcdir="."; suggested by Tim Van Holder.
3595 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3596 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3597 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3598 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
3599 does not mean "no --srcdir option".
3601 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3610 2005-08-12 Stepan Kasal <kasal@ucw.cz>
3612 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
3613 add "2>&1"; gzip 1.2.4 prints help on stderr.
3615 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3617 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
3618 was pushdef'ed twice while popped only once. Push it only once.

3635 Rewrite substantial part of lib/autoconf/status.m4.
3636 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3637 and CONFIG_COMMANDS are not processed in four separate loops.
3638 Instead, there is one main loop. This alows that the common code
3639 is expanded only once, thus config.status (and configure) is smaller.
3641 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3642 the AC_LIST_FILES and cousins macros are no longer used.
3644 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3645 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3646 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3647 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3648 contain the initialization, nor the for loop, nor the associated
3649 commands; all these go to ...
3650 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3651 _AC_OUTPUT_CONFIG_STATUS.
3652 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3653 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3654 (_AC_OUTPUT_FILE): The creation of the sed script ...
3655 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3656 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3657 _AC_OUTPUT_MAIN_LOOP.
3658 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3659 _AC_CONFIG_COMMANDS): Use ...
3660 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3661 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3662 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3663 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3664 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3665 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3666 ... new macros.
3667 (_AC_CONFIG_UNIQUE): Update.
3668 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3669 Replaced by this ...
3670 (_AC_LIST_TAGS): ... new common macro.
3671 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3672 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3673 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3674 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3675 this didn't belong to the `config commands' section.
3676 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3677 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3678 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3679 to the `config commands' section either.
3680 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3681 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3683 ... and many changes to the comments nearby.
3685 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3686 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3687 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3688 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
3689 (#define header templates): The comment at the top of the generated
3690 header now includes the name(s) of the source file(s).
3692 Several unrelated small changes:
3694 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
3695 parameter to AC_DIAGNOSE.
3696 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
3697 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
3698 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
3699 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
3700 with AU::AC_OUTPUT.
3701 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
3702 in AC_OUTPUT doesn't double-quote it either.
3703 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
3704 parameters.
3706 2005-07-10 Stepan Kasal <kasal@ucw.cz>
3708 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
3709 versions of Portland Group compiler produce single- and double-quoted
3710 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
3711 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3713 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3715 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3716 This is a corrected version of yesterday's patch.
3718 2005-07-07 Stepan Kasal <kasal@ucw.cz>
3720 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
3721 path, too; insert a "===" to emphasize the line.

3724 ac_cv_build_alias to ac_build_alias.
3725 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3727 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3728 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3729 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3730 (AC_ARG_VAR): ... here.
3731 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3732 target_alias.
3734 Keep a list of all precious variables and process them with one simple
3735 for loop, instead of expanding all commands, or, OTOH, complicated
3736 processing of output of "set".
3737 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3738 variable names in new macro...
3739 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
3740 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
3741 a loop to assign all ac_env_* and ac_cv_env_* variables.
3742 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3743 to INIT_PREPARE.
3744 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3745 its value to shell variable ac_precious_vars and call
3746 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
3747 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
3748 _AC_ARG_VAR_VALIDATE.
3750 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
3751 and the AC_SUBSTs ...
3752 (AC_INIT): ... here.
3754 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
3755 the ac_subst_files section in config.log.
3757 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

3766 Fix problems reported by Nicolas Joly.
3767 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
3768 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3769 They are generated by the Tru64 v5.1B shell.
3771 2005-07-05 Stepan Kasal <kasal@ucw.cz>
3773 Fix my changes from 2005-07-01; reported by Noah Misch.
3774 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
3775 description, the macro now accepts only a single tag.
3776 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
3778 Fix cases when the varsions of Autoconf and Autotest don't match.
3779 Reported by Noah Misch.

3781 at_top_builddir, for compatibility with older autotest.
3782 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
3783 is not set, use at_top_builddir, for compatibility with older
3784 versions of autoconf.
3786 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
3788 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
3789 Problem reported by Patrick Welche.
3791 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
3793 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
3794 sed substitution command, so that we allow | in program prefixes
3795 and program suffixes. (& is a problem anyway; we're not fixing
3796 that here.)
3797 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
3798 configure_input, top_builddir, srcdir, etc.
3799 * lib/autotest/general.m4 (AT_INIT): Likewise, for
3800 PATH_SEPARATOR in AUTOTEST_PATH.
3802 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
3804 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
3805 for loop over config.site files using `set', to allow
3806 directory names containing IFS characters.

3810 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
3811 directories with weird names. Apparently some people like living

3832 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
3833 document to output the default config_* lists to config.status.
3834 Don't recognize option --file, if the functionality is not there.
3835 Likewise for --header; moreover, recognize --he and --h as shortcuts
3836 for --help in that case.
3838 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
3839 matches the order of execution. No code changed.

3860 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
3861 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
3862 (AC_SUBST): Call it.
3863 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
3864 the directory specific variables; but don't call it for configure_input.
3866 2005-06-28 Derek Price <derek@ximbiot.com>
3868 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
3869 addition.
3871 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
3873 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
3874 directory have inherent problems with special characters like spaces,
3875 due to limitations in Make syntax. Problem reported by Alexandre
3876 Duret-Lutz.
3877 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
3878 Also, fix Tru64 porting problem with shell patterns,

3892 variable into diagnostic. Make the diagnostic an error, not a warning,
3893 because we really don't support spaces and suchlike in dir names.
3894 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3895 Don't worry about backslashes in srcdir; it can't happen now.
3896 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
3897 Simplify ac_optarg handling.
3898 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

3906 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
3908 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
3909 that '\|' is not allowed in BREs; recommend using newline separated
3910 list of patterns instead of multiple -e options.
3912 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
3914 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

3920 2005-06-21 Stepan Kasal <kasal@ucw.cz>
3922 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
3923 b, t, r, w commands require single space, while : cannot have any.
3924 (Special Shell Variables): Fix sed code this in the example.
3925 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
3926 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
3928 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
3929 expand to the empty list. Don't use two pairs of m4_changequote,
3930 it's not necessary.
3932 2005-06-20 Derek Price <derek@ximbiot.com>
3934 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
3936 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
3938 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
3939 * doc/autoconf.texi:
3940 Don't mention Solaris versions so much, if a
3941 problem is common to all extant versions of Solaris. Say "SunOS
3942 4" instead of "SunOS" for SunOS 4.
3943 (awk): Mention more of the limitations of traditional Awk.
3944 (cat): Don't talk about cat -v.
3946 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
3948 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
3949 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

3951 to be compatible with glibc strverscmp.
3952 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
3954 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
3955 on Mac OS X 10.4 reported by Peter O'Gorman in:

3957 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
3958 Use shell builtins rather than 'expr', to work around expr bug.
3960 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
3962 * doc/autoconf.texi: "filesystem" -> "file system".
3963 "behaviour" -> "behavior".

3976 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
3977 quotes and backslashes. Patch from Derek Price.

3982 AS_TR_SH.
3984 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
3986 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3987 -u, since it outputs chatter if the input files are the same.
3988 Problem reported by Ralf Menzel.
3990 2005-06-08 Derek Price <derek@ximbiot.com>
3992 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3993 renaming them since they are about to be redefined anyhow.
3995 2005-06-08 Derek Price <derek@ximbiot.com>
3997 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3998 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3999 Move m4_undefine to alphabetical order.
4001 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4003 * README: Recommend GNU M4 1.4.3 or later.
4004 * doc/autoconf.texi (Introduction): Likewise.
4005 Reword to avoid some formatting glitches.
4006 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4007 Clarify explanation of HP compiler bug.
4008 Redo example output tp match current CVS snapshot.
4009 Use @example.org in email addresses when the examples
4010 might get inadvertently cut-and-pasted into user code.
4011 Remove example of autom4te usage that doesn't seem to work now.
4012 Use modern AC_INIT (except when the example is meant to be
4013 shown with Autoconf 2.13).
4014 Update ksh info for Solaris 9 and later.
4015 KB -> kB.
4016 Modernize description of Automake versions a bit.
4017 Don't claim a future version of Autoconf is near.

4023 follows its own advice about quoting better.
4024 Reword to avoid some formatting glitches.
4025 * doc/installt.exi: Reword to avoid some formatting glitches.
4027 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4028 Tru64 ksh pattern matching bug. Reported against Libtool by
4029 Albert Chin <libtool@mlists.thewrittenword.com> and
4030 Nicolas Joly <njoly@pasteur.fr>.
4032 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4034 m4_cdr of one-member list was [[]] (one-member list containing an
4035 empty string) instead of [] (an empty list. Callers were skewed to
4036 match this misbehaviour. As a consequence of this:
4037 - m4_foreach([x], [], [foo]) expanded to `foo', while
4038 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4039 This bug has been fixed:
4041 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4042 expand to an empty string; print error msg if called without
4043 an argument list.
4044 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4045 misbehaviour; handle [] and [[]] correctly.
4047 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4049 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
4050 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
4051 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4053 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4055 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4056 swallow records with more than 99 fields.
4057 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4058 parse the long line.
4060 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4062 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4063 swallow literals longer than 399. Reported by Ralf Wildenhues.
4064 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4065 to workaround this limitation.
4067 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4069 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4070 to gfortran, and make these the first two compiler names
4071 checked (following the general autoconf preference for gcc).
4073 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4075 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4076 (DISTCLEANFILES): Remove $(check_SCRIPTS).

4081 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4082 expression of unbounded size when processing the --list
4083 option. This runs afoul of a limit of 399 bytes per regular
4084 expression on AIX. Problem reported by Ralf Wildenhues.
4086 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
4088 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
4089 * doc/autoconf.texi (Particular Headers): Reword example
4090 for multiline stdbool replacement.
4091 (Setting Output Variables): Reword text a bit. Don't
4092 give all the details about |#_!!_#|.
4093 Reword description of line replacement.
4095 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4097 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4098 now contain newlines, and substituted files must be referenced on
4099 a line alone; the sed scripts to substitute them are now very
4100 different.
4101 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4102 commands can be put in a sed script portably.
4103 * doc/autoconf.texi (Setting Output Variables): Document above
4104 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4105 use of multiline substitution.
4106 * tests/torture.at: No longer expect substitution of newline to fail.
4108 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
4110 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
4111 From Ralf Menzel (trivial change).
4113 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
4115 * tests/local.at: Don't attempt to check for negated character
4116 classes in shell scripts. The test was too brittle.
4118 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4120 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4121 * doc/autoconf.texi (Limitations of Builtins): Document this
4122 limitation.
4124 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4126 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4127 common code; used in many places in the tree.
4128 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
4129 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4131 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4133 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4134 messages when ac_unique_file is not found.
4135 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4136 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4137 commands, for consistency with AC_MSG_ERROR and such.
4139 * bin/autoconf.as: Make more use of "shift 2" in option processing.
4141 * bin/Makefile.am: Merge the two rules for creating scripts.
4143 2005-05-23 Stepan Kasal <kasal@ucw.cz>
4145 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
4146 obsolete; it was never documented.
4147 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
4149 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4151 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4152 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4153 (ac_top_builddir): ... this ...
4154 (ac_top_build_prefix): ... to this; the old name is also kept, for
4155 backward compatibility.
4156 (ac_top_builddir_sub): New variable, without the trailing slash,
4157 always nonempty.
4158 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4159 * doc/autoconf.texi (Configuration Actions): Rename
4160 ac_top_builddir to ac_top_build_prefix.
4161 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
4162 at_top_builddir to at_top_build_prefix.
4163 * lib/autotest/general.m4 (AT_INIT): Likewise.
4165 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4167 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
4168 of confdefs.h .
4170 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4172 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4173 argument to m4_foreach. I guess it was necessary in the past,
4174 but I think it's a no-op now.
4176 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4178 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4179 ``cat <<_ACEOF'' commands to one.
4180 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4181 * lib/autoconf/status.m4: On various places, use expr instead of
4182 ``echo|sed.''
4183 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4184 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4185 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4186 a range.
4187 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4188 the wrong patterns between ``case'' and ``esac.'' The previous
4189 code had false positives.
4191 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4193 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4194 as on 2005-05-02.
4195 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
4196 Mention LIBOBJDIR.

4236 2005-05-13 Stepan Kasal <kasal@ucw.cz>
4238 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
4239 check.
4240 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
4241 enough arguments, similarly as in m4_bpatsubsts.
4243 2005-05-12 Stepan Kasal <kasal@ucw.cz>
4245 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
4246 of absolute paths.
4248 2005-05-11 Stepan Kasal <kasal@ucw.cz>
4250 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
4251 for absolute directory names in one loop.
4252 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
4253 abbreviations of --version and --debug.
4255 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
4257 * doc/autoconf.texi (Autoconf Language): Be more precise about
4258 quoting rules. Problems noted by Stepan Kasal.
4259 Also, throughout this document, be more careful about white space.
4260 "blank", "white space", and "space" all have different meanings
4261 and we should be careful to say what we mean.
4263 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4265 Fix C++ related problems reported by Werner Lemberg.
4266 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
4267 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
4268 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
4269 avoid problems with C++ and throw.
4270 * tests/compile.at: .cpp, not .cc.
4272 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
4274 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4276 * doc/autoconf.texi (Generic Functions): Typos.
4278 2005-05-02 Gary V. Vaughan <gary@gnu.org>
4280 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
4281 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
4282 set by latest automake.
4284 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4286 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
4287 outputs 0 on GNU/Linux these days.
4289 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4291 * doc/autoconf.texi (Autoconf Language): Add more description
4292 about quoting heuristics.
4293 (Limitations of Builtins): Describe "set -" problems.
4295 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4297 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4298 not newline.
4300 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4301 by AC_DEFINE; it was a mistake.
4302 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4304 2005-04-25 Stepan Kasal <kasal@ucw.cz>
4306 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
4308 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4310 * doc/autoconf.texi (External Software): Quadrigraphs are not
4311 processed correctly in AS_HELP_STRING; avoid this in the examples.
4312 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4313 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4314 comment and reduce m4_default([foo], []) to [foo].
4315 (m4_strip): Update the explanation.
4317 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4319 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4320 Remove core.conftest.* too; it's generated by Tru64 5.1.
4321 Problem reported by Jennis Pruett.
4322 * lib/autoconf/functions.m4
4323 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4324 Don't bother to remove core files; AC_RUN_IFELSE should do that
4325 for you.
4327 2005-04-19 Stepan Kasal <kasal@ucw.cz>
4329 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
4331 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
4333 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.

4336 2005-04-15 Stepan Kasal <kasal@ucw.cz>
4338 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
4339 the comment.
4341 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
4343 * doc/autoconf.texi (External Software, Package Options): Add
4344 examples showing how to implement --with-* and --enable-* options.
4346 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
4348 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
4349 as well as configure.in. Problem reported by Gregorio Guidi.
4351 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
4353 * doc/autoconf.texi (Particular Functions): Use gnulib's current
4354 pattern for alloca snippet.
4356 2005-04-04 Stepan Kasal <kasal@ucw.cz>
4358 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

4364 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
4366 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
4367 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
4369 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4371 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4372 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4373 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4374 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4375 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4377 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4379 * NEWS: The configure command now warns you if you attempt to use
4380 a directory whose name contains a special character like space,
4381 newline, or "\".
4382 * doc/autoconf.texi (Installation Directory Variables): Allow
4383 "," in file names. Do not use \@; it's not a portable regexp.
4384 * bin/Makefile.am (edit): Likewise.
4385 * lib/Makefile.am (edit): Likewise.
4386 * tests/Makefile.am (edit): Likewise.
4387 * tests/semantics.at: Likewise.
4388 * tests/torture.at: Likewise.
4389 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
4390 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
4391 * doc/autoconf.texi (File System Conventions): Warn about
4392 unportable file names.
4393 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4394 (AC_INIT): Use it.
4395 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4396 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4397 ac_pwd, and quote srcdir.
4398 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4400 * doc/autoconf.texi: Fix some systematic formatting problems.
4401 ".)" needs a following @: if not at the end of a sentence, and
4402 similarly for "!)". "etc." should be preceded by a comma.
4403 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4405 2005-03-22 Bruno Haible <bruno@clisp.org>
4407 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4408 argument is often called 'build-aux'.
4410 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4412 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4413 macro AC_TRY_LINK is obsolete.
4414 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4415 `AC_CONFIG_FILES'.
4417 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4419 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4420 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4421 from a Common Lisp's `cl'.
4422 (AC_PROG_CXX): Behave according to the documentation: don't
4423 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4424 make the variable CCC precious; use `cl.exe', not `cl'.
4426 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4427 Alexandre Duret-Lutz <adl@gnu.org>
4429 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4430 /dev/null, as "configure" shouldn't read stdin, and this insulates
4431 us from problems (e.g., when testing for "cl"). Also, do this
4432 redirection before invoking "hostname" or "uname", and keep the
4433 original input stream available via...
4434 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4435 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4436 bother with "</dev/null" since it's now done at the top of
4437 'configure'.
4438 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4439 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4440 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4441 * doc/autoconf.texi (File Descriptor Macros): New section.
4442 (Printing Messages): Mention it.
4443 * tests/base.at (Input/Output): New test.
4445 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4447 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4448 newline if neither \c nor -n work, as that would output two
4449 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4451 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4453 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4454 This causes that any required macros inside will get before the if.
4455 * doc/autoconf.texi (autom4te.cache): A typo.
4457 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4459 Undo previous change, except keep the change to
4460 lib/autoconf/programs.m4 that replaced grep with shell
4461 pattern-matching. This is because net-snmp configure reads stdin.
4462 Reported by Noah Misch.
4464 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4466 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4467 from /dev/null, as "configure" shouldn't read stdin, and this
4468 insulates us from problems (e.g., when testing for "cl").
4469 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4470 before invoking "hostname" or "uname".
4471 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4472 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4473 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4474 "</dev/null" since it's now done at the top of 'configure'.
4475 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4476 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4477 Also, replace grep with shell pattern-matching, to save a process.
4479 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4481 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4482 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4483 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4484 compiler.
4486 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4488 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4489 grep -q isn't portable. Improve grep -s explanation.
4490 Problem reported by Dan Manthey.
4492 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4494 * doc/autoconf.texi (Special Shell Variables): Clarify
4495 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4497 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4499 * doc/autoconf.texi: Use @acronym for DJGPP.
4500 Fix some @code's that should have been @env's, and vice versa.
4501 Sort environment variable names.
4502 Mention that shells no longer inherit IFS.
4503 Don't recommend PATH_SEPARATOR=';' so strongly.
4504 Mention that $RANDOM might expand to the empty string.
4505 "symlink" and "soft link" -> "symbolic link".
4506 Improve mktemp description (reported by Bruno Haible).
4508 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
4510 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
4511 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
4512 Likewise.
4513 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
4514 Likewise.
4516 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
4518 * NEWS: Mention AT_COPYRIGHT.

4521 than copying them.

4546 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
4547 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

4582 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4584 Try not to generated lines of unlimited length, as POSIX places a
4585 2047-byte limit on line length of portable text files.
4586 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
4587 Use newline as a separator, not space.

4645 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4646 Update the long comment explaining it.
4648 m4_require no longer writes an ``is required by'' line to the
4649 execution stack. It contains only one bit of non-redundant
4650 information: that the macro was required, not called. And even
4651 this bit is useless in most situations: have you ever met a macro
4652 which both calls and requires the same macro?
4654 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4655 (_m4_defun_pro_outer): ... only via this macro, for the outermost

4662 (_m4_require_call): Use it.
4663 * tests/m4sugar.at (m4_require): Expect output without the
4664 ``is required by'' messages.
4666 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4668 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4669 rather than x for expr.
4671 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
4672 this is safe.
4673 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
4674 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

4689 config.h.in is always recreated when --force.

4695 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
4697 * doc/autoconf.texi (Limitations of Builtins): Clarify that

4700 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
4702 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
4703 Warn about newline stripping in `` and $(). Update Solaris
4704 version to 9.
4705 (Limitations of Builtins): Use expr "X...", not expr "x...", as
4706 X insulates us from future changes to Posix.
4707 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
4708 stripping.
4710 2005-01-19 Stepan Kasal <kasal@ucw.cz>

4732 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
4734 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

4756 (_m4_divert_n_stack): New macro; the expansion is
4757 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
4758 otherwise.
4759 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
4760 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
4761 stored in _m4_divert_diversion or _m4_divert_dump.
4762 (m4_divert_pop): When the parameter is given, compare the symbolic
4763 name with the last diversion pushed on the stack. Previously, the
4764 current diversion was compared with the numeric value of the
4765 diversion given as the parameter.
4766 (m4_require): If the macro hasn't been expanded yet, call ...
4767 (_m4_require_call): this new macro.

4800 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

4853 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
4854 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

5046 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
5048 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
5049 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
5050 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
5051 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
5053 2004-12-07 Stepan Kasal <kasal@ucw.cz>
5055 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

5070 with exactly one parameter.
5072 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
5074 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5075 "char c = '\200';" rather than "char c = 0x80;" as the
5076 latter doesn't conform to the strict C standard due to
5077 overflow on signed char hosts.
5079 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
5080 to -qlanglvl=ansi. We don't want to disable extensions.

5084 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
5085 (Using Autotest, testsuite Scripts, Writing testsuite.at):
5086 Reword slightly to avoid some English-language problems noted

5138 2004-11-13 Stepan Kasal <kasal@ucw.cz>
5140 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
5141 the $1_found variable, don't test whether the file is executable;
5142 Both things are checked ...
5143 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
5144 the former ``test -f''.

5147 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

5179 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
5180 Problem reported by Stepan Kasal.
5182 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
5184 Fix problems reported by Andreas Buening in:
5185 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
5186 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
5187 in test makefile.
5188 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is

5191 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
5193 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5194 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5195 (trivial change). Problem and patch reported by Andrew Church in:
5196 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5198 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
5200 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

5203 Also, fix some minor spacing and punctuation bugs.

5223 * README: Add advice about m4 1.4.2.
5225 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5226 texinfo.tex for now (done by hand now).
5227 * Makefile.maint (wget_files, cvs_files):
5228 Remove ansi2knr.c; nobody uses it.
5229 (ansi2knr.c-url_prefix): Remove.
5230 (cvs-update): Fix test for failure. I don't know why it ever
5231 worked...
5233 * doc/autoconf.texi: Update URLs, some of which went stale.
5234 Use @uref rather than @href.
5236 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5237 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5239 * config/config.guess, config/config.sub, config/elisp-comp,
5240 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5241 doc/fdl.texi, doc/standards.texi: Sync with master copy.
5243 * NEWS, TODO, configure.ac, bin/autoscan.in,
5244 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
5245 doc/install.texi, lib/Autom4te/Configure_ac.pm,

5249 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
5250 tests/tools.at, tests/torture.at:
5251 Use "file name" rather than "filename" or "path",
5252 to be consistent with the terminology of the GNU coding standards.
5254 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5256 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5257 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5258 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5259 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5261 More fixes to support spaces in the name of the build directory.
5262 This isn't a complete fix but it's an improvement.
5264 * bin/autoconf.as (autom4te_options): New var.
5265 Use it instead of appending to AUTOM4TE, so that we can allow
5266 spaces in the build directory's absolute name.
5267 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5268 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

5271 main program): Likewise.
5273 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
5275 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
5276 From Ralf Corsepius in:

5279 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
5281 * doc/autoconf.texi (Function Portability): Document isinf and
5282 and isnan. From a suggestion by Kevin Ryde.
5284 * lib/Autom4te/General.pm (END): Return correct exit status even
5285 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5287 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5289 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5290 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5291 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5293 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5295 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5296 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5297 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5298 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5299 * lib/autom4te.in (Automake-preselections): Preselect
5300 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5302 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5304 * lib/autom4te.in (Automake-preselections): Preselect
5305 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5306 trace them.
5308 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5310 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5311 Tru64.
5312 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5313 Document problem with "`""`" in pdksh POSIX mode.
5315 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5317 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5318 with pdksh, too. Problem reported by Patrick Welche via
5319 Gary V. Vaughan.
5320 * doc/autoconf.texi (Shellology): Note that set -o posix is
5321 useful for pkdsh, too.
5323 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5325 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5326 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5327 Don't fail if ENV or BASH_ENV is readonly.
5328 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5329 etc. are read only. Problem reported by Ludovic Courtes.
5331 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5333 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is

5335 (trivial change)
5337 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5339 * doc/autoconf.texi (File System Conventions): Warn about
5340 names like "aux". Problem reported by Eric Blake.
5342 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5343 by zero instead of array size, so that we can use any arithmetic
5344 constant expression (instead of requiring an integer constant
5345 expression). This allows us to test expressions like DBL_MAX <
5346 LDBL_MAX, which didn't conform to the C standard using the old
5347 method.
5348 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5349 now that we can do floating-point tests at compile time.
5351 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5353 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5354 and LDBL_EPSILON, as the resulting expression isn't an
5355 integer constant expression and violates the C standard.
5356 Problem reported by Nelson H. F. Beebe. Also, check
5357 for "L" suffix, and check that long double doesn't have
5358 worse range or precision than double, that mixed-mode
5359 arithmetic doesn't generate a diagnostic, that double
5360 constants fit in long double.
5362 2004-06-03 Kevin Ryde <user42@zip.com.au>
5364 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5365 malloc(0) and realloc(NULL,size).
5367 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5368 Bob Proulx.
5370 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5372 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5373 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5374 by Jim Meyering.
5376 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5378 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5379 can be rewritten using if-then-else. Suggested by Bruno Haible.
5381 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5383 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5384 Problem reported by Stepan Kasal.
5386 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5388 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5389 change). Patch reported by Ralf Wildenhues in
5390 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5392 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5393 function F exists if the compiler and linker let you compile an
5394 expression like (F != 0). Recent versions of GCC optimize away
5395 the reference to F in that case, since every function address must
5396 be nonzero, so the link succeeds even if F does not exist.
5397 Problem reported by Manu in
5398 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5400 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5401 "Unix". Many uses changed.
5402 (Limitations of Builtins): Explain better why the ! command isn't
5403 portable.
5405 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5407 * lib/autom4te.in (Automake-preselections): Preselect
5408 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5410 2004-05-19 Kevin Ryde <user42@zip.com.au>
5412 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5413 referencing AC_FUNC_STRERROR_R.
5415 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5416 note pessimistic assumption when cross compiling.
5418 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5420 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5421 (until 2004) invoked subcommands with sh -e, contra POSIX.
5422 Reported by Kevin Ryde.
5424 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5426 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5427 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5428 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5429 `test -f " /usr/bin/grep"', which _always_ failed.
5430 (AC_PROG_SED): Ditto bogus PATH fix.
5431 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5432 requires that grep correctly supports _multiple_ `-e' options, rather
5433 than stating only that grep should accept `-e'.
5435 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5437 Port to C99, which requires that 'exit' be declared.
5439 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5440 to ensure that stdlib.h is included.
5441 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5442 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5443 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5444 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5445 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5446 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5447 when using 'exit' in a test; C99 requires that 'exit' be declared.
5449 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5451 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5452 now prefers 'grep' implementations that accept -e.
5453 (Limitations of Usual Tools): Describe problems of traditional
5454 egrep and fgrep with long input lines, and of traditional grep
5455 with -e.
5456 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5457 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5458 All callers changed. Append /usr/xpg4/bin to the PATH, for
5459 Solaris.
5460 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5461 the user with complaints about multiple -e options.
5462 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5463 Define it with AC_PROG_GREP.
5464 * configure.ac (AC_PROG_GREP): Add.
5465 * lib/freeze.mk (GREP): New macro.
5467 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5469 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5470 a possible candidate only after all others fail, rather than
5471 consulting it first. This improves backward compatibility by
5472 better reflecting the way shell selection occurred in previous
5473 versions of Autoconf, and should help to avoid triggering latent
5474 problems in other packages, such as the one in Automake where zsh
5475 is not handled robustly:
5476 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5477 Although it is not Autoconf's responsibility to work around
5478 problems in Automake, it nevertheless makes sense to avoid
5479 introducing unnecessary incompatibilites.
5481 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5482 Gary V. Vaughan <gary@gnu.org>
5484 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5485 how deeply nested we are when a suitable tool is found, set the
5486 ac_path_TOOL_found flag.
5487 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5488 nested we are in this macro. Break out of all 3 nested loops if
5489 ac_path_TOOL_found is set.
5491 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5493 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5494 of the _AS_PATH_WALK loop too if GNU flavor is found.
5496 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5498 * doc/autoconf.texi (Limitations of Make): Update documentation
5499 for `$<'. New entry `Long lines', based on a report from Simon
5500 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5501 paragraph about DJGPP, based on a mail from Richard Dawe.
5503 2004-04-20 Paul Eggert <eggert@twinsun.com>
5505 * tests/c.at (C keywords): Don't assume that GCC supports
5506 "restrict" and "inline", as sufficiently-old GCC versions do not
5507 (also, GCC configured to be in pedantic C89 mode does not).
5508 Problem reported by Sumit Pandya in:
5509 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5511 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5512 consider -g to work if it generates warnings when plain compiles
5513 don't. Problem reported by Braden McDaniel in:
5514 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5516 * doc/autoconf.texi (Slashes): New section, to document a problem
5517 reported by Jim Meyering in:
5518 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5520 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5521 linker output files before linking, to work around IRIX 6 linker bug.
5522 Problem reported by Rainer Orth in:
5523 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5525 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5527 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5528 best tool so far counter rely on the tool path variable name to
5529 avoid checks for one tool being affected by the results of running
5530 the length check on a previous tool.
5532 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5533 match expression argument, as different greps have different
5534 regular expression flavours.
5535 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5536 literals.
5537 (AC_PROG_EGREP): Pass 'EGREP$'.
5538 (AC_PROG_GREP): Pass 'GREP$'.
5540 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
5542 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
5543 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
5545 2004-03-29 Paul Eggert <eggert@twinsun.com>
5547 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
5548 Types, Specific Compiler Characteristics, System Services,
5549 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5550 etc. consistently instead of 'long', 'short', 'unsigned' etc.
5551 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
5552 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
5553 Likewise.
5554 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
5555 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
5556 AC_TYPE_OFF_T): Likewise.
5557 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
5558 Likewise.

5561 pacify libtool 1.5.2. Fix quoting problems in sed command.
5563 2004-03-28 Paul Eggert <eggert@twinsun.com>
5565 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
5566 now defines HAVE_DECL_TZNAME if it is declared, when
5567 HAVE_STRUCT_TM_TM_ZONE is not defined.
5568 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5569 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
5570 for HAVE_TZNAME.
5572 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
5574 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
5575 superfluous backslashing of quotes (") in sed expressions;
5576 thanks to Paul Eggert.
5578 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
5580 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
5581 Fortran compiler is ifort, also added pghpf; thanks to Nelson
5582 H. F. Beebe for the bug report.
5584 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
5586 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
5587 quoted -cmdline argument in Portland Group compiler (bug
5588 reported by Jeffrey J. Barteet).
5590 2004-03-25 Kevin Ryde <user42@zip.com.au>
5592 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
5593 (Run Time): ... here, where it's now mentioned.

5597 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
5598 inherits from language Autoconf-without-aclocal-m4.
5599 (Customizing autom4te): Adjust example; the cache must now be
5600 disabled for language Autoconf-without-aclocal-m4.

5614 AC_CHECK_TOOLS.
5615 (Specifying Names): Document the reason for these future
5616 behavioral changes.
5617 * tests/mktests.sh: Do not generate tests for the
5618 new macros.
5619 * NEWS: Document these changes.
5621 * doc/autoconf.texi: Avoid macros with unbraced arguments,
5622 they make TeX hang up.

5627 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5628 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
5629 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
5630 vowel.
5631 (AC_CHECK_ALIGNOF): New macro.
5632 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
5633 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to

5636 2004-03-03 Paul Eggert <eggert@twinsun.com>
5638 * bin/Makefile.am (edit): Don't use $< in a context where
5639 POSIX doesn't require support for it. Use $@.in instead.
5640 Problem reported by Anthony N. Frasso in
5641 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
5642 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
5644 2004-02-23 Gary V. Vaughan <gary@gnu.org>
5646 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
5647 from the next generation of Libtool.

5650 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5652 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
5653 is not always thread-safe. Report from Nathanael Nerode.
5655 2004-02-18 Paul Eggert <eggert@twinsun.com>
5657 Fix a dependencies problem, stemming from a Autoconf 2.59 build
5658 problem on QNX reported by Stephen Rasku in
5659 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
5661 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
5662 $(m4sh_m4f_dependencies); this removes a FIXME.
5663 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
5664 (MAINTAINERCLEANFILES): Split into pieces,
5665 one per related section. Add $(srcdir)/wrapper.in.
5667 2004-02-09 Paul Eggert <eggert@twinsun.com>
5669 * doc/autoconf.texi (Setting Output Variables): Emphasize that
5670 AC_SUBST provides no portable way to escape literal newlines.
5672 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5673 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5674 Darwin uses -lcrt2.o and there's little point to cataloging all
5675 the system variants. Partial fix reported by Andreas Waechter in:
5676 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
5677 for bug reported by Nelson H. F. Beebe in:

5682 * doc/autoconf.texi (AU_DEFUN): Fix English,
5683 suggested by Paul Eggert.
5684 * lib/autoconf/autoupdate.m4: Correct reference to
5685 acobsolete.m4, suggested by Alexandre Duret-Lutz.
5687 2004-02-02 Paolo Bonzini <bonzini@gnu.org>

5690 refer to the correct file.
5691 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
5692 the behavior of the third argument.
5693 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
5694 correctly the behavior of the third argument. Document
5695 what the three macros that AU_DEFUN defines do. Fix
5696 warning message when the third argument includes $0
5697 (reported by Alexandre Duret-Lutz).
5699 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5700 Eric Sunshine <sunshine@sunshineco.com>
5701 Paul Eggert <eggert@twinsun.com>
5703 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
5704 (AS_INIT): Output shell initialization there. Removed optional
5705 parameter. Expand _AS_SHELL_FN_SPY.
5706 (AS_INIT_WITH_SHELL_FN): Removed.
5707 (_AS_SHELL_FN_SPY): New macro.
5708 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
5709 macros.
5710 (AS_SHELL_SANITIZE): Remove loop to find better shell
5711 and documentation for the parameter.
5712 (_AS_DETECT_BETTER_SHELL): Move it here.

5714 (_AS_RUN): Move it here, support testing with eval.
5715 (AS_REQUIRE_SHELL_FN): Require shell functions when
5716 it is used.
5717 (_AS_LINENO_WORKS): Put around braces, we do not
5718 trigger the bash bug anymore.
5719 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
5720 use AS_INIT_WITH_SHELL_FN.
5721 * bin/autoconf.in, tests/wrapper.in: Regenerated.
5723 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

5740 * lib/autoconf/status.m4: Remove FIXME.
5741 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
5742 that the macro is not present anymore in the updated
5743 configure.ac.
5744 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
5745 of autoupdate.

5751 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
5752 2003 (except 1997) to the list of copyright years. This undoes
5753 the 2003-05-22 change, which removed the older years from the list.
5754 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
5756 2004-01-27 Gary V. Vaughan <gary@gnu.org>

5762 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
5763 AC_PROG_GREP.
5764 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
5765 egrep and fgrep respectively if $GREP -E/-F don't work.
5766 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
5767 _AC_PROG_GREP, and AC_PROG_SED.
5768 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
5769 longest input length accepted by a command.
5770 (AC_PROG_SED): Use it.
5771 * doc/autoconf.texi (Particular Programs): Document the changes.
5772 * NEWS: Updated.
5774 2004-01-27 Paul Eggert <eggert@twinsun.com>

5796 sources.
5798 2004-01-26 Paul Eggert <eggert@twinsun.com>
5800 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
5801 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
5802 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
5803 not <inttypes.h>. Problem reported by Tim Mooney in
5804 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
5805 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
5806 Likewise.
5808 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
5809 otherwise "make check" fails because it forbids cmp (I guess
5810 because cmp treats files as binary on DOS-like systems).
5812 * tests/mktests.sh: Update copyright date to 2004, since some tests
5813 have changed in 2004.
5815 2004-01-23 Gary V. Vaughan <gary@gnu.org>
5817 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
5818 non-truncating sed or gsed program in PATH.
5819 * tests/acprograms.at: Add it.
5820 * doc/autoconf.texi (Particular Programs): Document it.
5821 * NEWS: Updated.

5825 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
5826 -std1 disables some useful extensions on Tru64. Problem reported
5827 by N. Lichtmaier in
5828 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
5830 2004-01-14 Paul Eggert <eggert@twinsun.com>
5832 * doc/autoconf.texi (Programming in M4sh): Document that
5833 AS_MKDIR_P succeeds if the destination is a symbolic link
5834 to an existing directory.
5835 (Limitations of Usual Tools): Note that mkdir -p might not
5836 succeed on symlinks to directories.
5838 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
5840 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

5847 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
5848 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
5850 2004-01-10 Jim Meyering <jim@meyering.net>
5852 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
5854 2004-01-09 Paul Eggert <eggert@twinsun.com>
5856 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning

5859 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
5860 AC_COMPILE_IFELSE, since we now assume our caller invokes
5861 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
5862 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
5863 of AC_RUN_IFELSE; this avoids the warning mentioned above.

5868 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
5869 `"'...'"`, as it's confusing (and I suspect it may not work on
5870 some platforms). The code was incorrect anyway, as it assumed
5871 that \$ evaluated to itself in that context. Reported by
5872 Alexandre Duret-Lutz.

5986 does not work.
5987 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

6345 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6346 directory for AC_CONFIG_COMMANDS' first argument exists.
6347 This makes valid the invocation of _AC_SRCPATH that follows.
6348 Reported by Eric Sunshine.
6349 * doc/autoconf.texi (Configuration Commands): Adjust.
6351 2003-09-26 Akim Demaille <akim@epita.fr>
6353 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6354 Reported by Ralf Corsepius.
6356 2003-09-26 Akim Demaille <akim@epita.fr>
6358 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6359 arguments.
6360 Actually, use AU_ALIAS.
6361 From Bruno Haible.
6363 2003-09-26 Paul Eggert <eggert@twinsun.com>
6365 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
6366 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
6367 Problem reported by Eric Sunshine in:
6368 http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html
6370 2003-09-26 Akim Demaille <akim@epita.fr>
6372 The test suite are sometimes assigning timings incorrectly.
6373 Reported by Henk Krus.
6374 Diagnosed by Nicolas Joly.
6376 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6377 AT_help_all.
6378 Instead of making AT_help a sequence of assignments to grow
6379 $at_help_all, just make AT_help_all be the growing contents of
6380 $at_help_all, and make a single assignment in...
6381 (AT_INIT): here.
6382 (at_times_skip): Flip the meaning and rename as...
6383 (at_times_p): this.
6384 (AT_INIT): When summarizing the test that ran, remove
6385 $at_times_file after use, and check it is present before trying to
6386 use it.
6388 2003-09-25 Akim Demaille <akim@epita.fr>
6390 Version 2.57d.
6392 * bin/Makefile.am (edit): Handle '@configure_input@'.
6393 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6394 (ifnames): chmod -w.
6395 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6396 executables, not bin/ executables! Otherwise all the magic needed
6397 to find non installed files is turned off. This caused a failure
6398 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6399 as found in its environment (sent by tests/autoreconf): pointing
6400 to bin/autom4te that could not find its files.
6401 * tests/mktests.sh: Force the replacement of generated files, for
6402 the sake of "mv" program that are interactive when overwriting a
6403 -w file.
6404 * config/install-sh: Upgrade from CVS Automake.
6406 2003-09-23 Paul Eggert <eggert@twinsun.com>
6408 * doc/autoconf.texi (Limitations of Builtins): Document test -h
6409 versus test -L issues.
6411 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
6412 Paul Eggert <eggert@twinsun.com>
6414 Trivial change to support GCC's configuration procedure.
6415 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6416 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6417 about inconsistency if the preprocessor is set to give errors for
6418 any warning.
6419 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6421 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
6423 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
6424 and XFile.pm from Automake.
6425 * lib/Autom4te/XFile.pm: Update from Automake.
6427 2003-09-12 Akim Demaille <akim@epita.fr>
6429 Version 2.57c.
6431 2003-09-12 Akim Demaille <akim@epita.fr>

6434 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
6435 from masters.
6437 2003-09-12 Akim Demaille <akim@epita.fr>
6439 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
6440 not asm/types.h.
6442 2003-09-11 Akim Demaille <akim@epita.fr>
6444 * doc/autoconf.texi (Header Portability): linux/random.h.
6445 From Peter Hendrickson.
6447 2003-09-10 Akim Demaille <akim@epita.fr>
6449 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6450 willing to edit the output files.
6452 2003-09-10 Akim Demaille <akim@epita.fr>
6454 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6455 and AC_FC_FREEFORM.
6456 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6457 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
6459 2003-09-09 Akim Demaille <akim@epita.fr>
6461 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
6462 Reported by Gary Vaughan.
6463 * bin/autom4te.in (handle_m4): Likewise.
6465 2003-09-09 Akim Demaille <akim@epita.fr>
6467 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
6468 trailing files.
6470 2003-09-07 Paul Eggert <eggert@twinsun.com>
6472 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
6473 Improve the accuracy of the wording about obsolescence.
6474 From a suggestion by Ian Lance Taylor in
6475 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
6477 2003-09-05 Paul Eggert <eggert@twinsun.com>
6479 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6480 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6482 2003-09-04 Akim Demaille <akim@epita.fr>
6484 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6485 AC_FUNC_WAIT3.
6487 2003-09-04 Akim Demaille <akim@epita.fr>
6489 * bin/autom4te.in: Use &fatal where more appropriate than &error.
6490 (freeze): When exiting, use $exit_code.
6491 * lib/autoconf/fortran.m4: Comment changes.
6493 2003-09-04 Akim Demaille <akim@epita.fr>
6495 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
6497 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6499 Add support for newer Fortran dialects. The F77 interface is
6500 unchanged, and continues to support Fortran 77. New FC macros
6501 correspond to all the old F77 macros, with output variables FC,
6502 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6503 available dialect, but older dialects can be specified. There are
6504 new macros AC_FC_SRCEXT to set the source extension, and
6505 AC_FC_FREEFORM to accept free-form source files.
6507 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
6508 New macros.
6509 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
6510 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

6512 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

6524 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
6525 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
6526 Rewrite in terms of the above.
6527 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
6528 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
6529 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
6530 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
6532 2003-09-02 Paul Eggert <eggert@twinsun.com>
6534 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
6535 Document problems with timestamp resolution that 'make', 'cp -p', and
6536 'touch -r' have.
6538 2003-08-27 Akim Demaille <akim@epita.fr>
6540 * tests/m4sugar.at (cross_warning): Make sure to enable the
6541 output, so that we can track spurious m4sugar output.
6542 * tests/local.at: Require 2.57.
6543 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
6544 are defaulted by AT_CHECK anyway.
6545 Use AT_CHECK_AUTOM4TE.
6546 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
6547 missing dnl.
6549 2003-08-27 Akim Demaille <akim@epita.fr>
6551 * bin/autoheader.in: Issue the "Using auxiliary..." message only
6552 when -Wobsolete is set.
6553 Set it on by default.
6554 Suggested by Klee Dienes.
6556 2003-08-27 Akim Demaille <akim@epita.fr>

6605 * bin/autom4te.in: Adjust to output the call stack.
6606 * tests/m4sugar.at (m4@&t@_warn): Adjust.
6608 2003-08-22 Akim Demaille <akim@epita.fr>

6615 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
6616 (&verbose): Remove.
6617 (&getopt): Adjust the note and verb channels, depending upon
6618 --verbose.

6620 * bin/autoupdate.in: Adjust.
6621 Use &verb, not &verbose.
6623 2003-08-21 Akim Demaille <akim@epita.fr>
6625 * bin/autoheader.in (&parse_args): Use &parse_warnings and
6626 &parse_WARNINGS.

6628 * bin/autoscan.in: Use Autom4te::ChannelDefs.
6629 * lib/Autom4te/General.pm: Don't export error: you don't own it.
6631 2003-08-21 Akim Demaille <akim@epita.fr>
6633 First stab at preserving warnings between calls to autom4te,
6634 including when the cache is used.
6636 There are still several issues: (i) there are too many runs of m4
6637 (one for include, one for warnings, and some more), (ii) warnings
6638 spreading on several lines are not handled gracefully, (iii) the
6639 code meant to have the call stack display for errors does not work
6640 (its handling should move from m4 to autom4te).
6642 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6643 Use them.
6644 (@preselect): Add m4_warn.
6645 ($exit_status): Remove, use $exit_code.
6646 ($help): Use Autom4te::ChannelDefs::usage.
6647 (&handle_m4): No longer define the m4_warnings.
6648 At each run, extract and report the warnings.
6649 Always cache the result, including if the exit status is on
6650 failure, since if nothing changes, we should result in the same
6651 failure, hence we can use the cache.
6652 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6653 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6654 Remove.
6655 (m4_warn): Redefine as a do-nothing: it is its invocation that
6656 matters, as warnings are now reported via traces.
6657 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6658 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6659 the latter reveals calls to the former.
6661 Adjust the tests.
6663 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6665 2003-08-21 Akim Demaille <akim@epita.fr>
6667 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
6668 Use them.
6670 2003-08-21 Akim Demaille <akim@epita.fr>
6672 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
6673 forward order.
6674 * lib/Autom4te/ChannelDefs.pm: Doc typos.
6675 (&parse_warnings): Accept a list of warning requests.
6676 (&usage): Return a string, not a side effect.
6677 (cross): New warning category.
6679 2003-08-21 Akim Demaille <akim@epita.fr>
6681 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
6682 (&require_configure_ac): Accept an optional directory argument.
6683 ($configure_ac): Remove.
6684 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
6685 (&catfile): Remove.
6686 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
6687 * bin/autoscan.in: Adjust.
6689 2003-08-20 Akim Demaille <akim@epita.fr>
6691 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
6692 Reported by Alexandre Duret-Lutz.
6694 2003-08-20 Akim Demaille <akim@epita.fr>
6696 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
6697 * bin/autom4te: Adjust.
6698 In particular, be Autoconf tools are really silent when properly
6699 working, bind the verbosity of the 'note' channel to $verbose.
6700 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
6701 (&xsystem, &contents): Remove, since they are exported by...
6702 * lib/Autom4te/FileUtils.pm: this.
6703 More perldoc.
6704 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
6705 * lib/Autom4te/FileUtils.pm: here.
6707 2003-08-20 Akim Demaille <akim@epita.fr>
6709 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
6710 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

6762 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
6763 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
6764 shorter column three. Add DESCRIPTION to log file content.
6766 2003-08-13 Derek Price <derek@ximbiot.com>
6768 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

6803 (trivial change). See:
6804 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
6805 (This really should be 'intptr_t', not 'long', but that would
6806 take more work.)
6808 2003-06-25 Akim Demaille <akim@epita.fr>
6810 * lib/Makefile.am (autom4te.cfg): Make it read only.
6811 Depend on Makefile since it contains substitutions.

6820 From Gareth McCaughan.
6822 2003-06-23 Akim Demaille <akim@epita.fr>
6824 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
6825 not all of them. This fixes 1. the fact that when testing
6826 Autoconf there are many many config.log, 2. the incorrect use of
6827 top_srcdir to find config.log.
6828 Don't mix the detailed output of failed test with the summary of
6829 failures. Rather, append detailed log afterwards.
6831 2003-06-23 Akim Demaille <akim@epita.fr>
6833 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
6834 always run: output config.log on $at_group_log.
6836 2003-06-23 Akim Demaille <akim@epita.fr>
6838 * tests/torture.at (#define header templates): Don't use quotes in
6839 C++ comments as it puzzles Emacs' sh font-lock-mode.
6841 2003-06-23 Akim Demaille <akim@epita.fr>
6843 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
6844 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
6845 * tests/atspecific.m4: Rename as...
6846 * tests/local.at: This.
6847 * tests/suite.at: Move the globals into...
6848 * tests/local.at: here.
6849 * tests/Makefile.am: Adjust.
6850 * doc/autoconf.texi (testsuite Scripts): Adjust.
6852 2003-06-21 Kevin Ryde <user42@zip.com.au>
6854 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
6855 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
6856 ensuring we add -std1 for full-ANSI.
6858 * doc/autoconf.texi (hdrindex): New macro.
6859 Add index entries for portability of various standard header files.
6861 2003-06-20 Akim Demaille <akim@epita.fr>
6863 * configure.ac: Bump to 2.57b.
6865 2003-06-20 Akim Demaille <akim@epita.fr>
6867 Version 2.57a.
6869 2003-06-20 Akim Demaille <akim@epita.fr>
6871 * bin/autom4te.in: Don't rely on $HOME being defined.
6872 Reported by Marc Espie as PR/233.
6874 2003-06-20 Akim Demaille <akim@epita.fr>
6876 * lib/autotest/general.m4: Use at_times_file only if used.
6877 From Nicolas Joly.
6879 2003-06-20 Akim Demaille <akim@epita.fr>
6881 * config/config.guess, config/config.sub, config/elisp-comp,
6882 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
6883 Update from masters.
6885 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
6887 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
6888 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
6889 (TEST_SCRIPT): New diversion.
6890 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
6891 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
6892 (AT_INIT): Support for expected failures.
6894 2003-06-02 Akim Demaille <akim@epita.fr>
6896 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
6897 changes.
6898 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
6899 Autoconf nor Automake.
6900 (&contents): New, from Automake.
6901 PODify.
6903 2003-05-28 Paul Eggert <eggert@twinsun.com>
6905 * NEWS, doc/autoconf.texi (Particular Functions),
6906 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
6907 is the inverse of localtime.
6909 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
6911 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
6912 (handle_exec_errors): New function. Work around $! being
6913 altered by WEXITSTATUS.
6914 (xqx, xsystem): Use handle_exec_errors.
6916 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
6918 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
6919 Do not call `_exit()', simply modify `$?'.
6920 (xsystem): Reset $! before running system, and check it afterward.
6921 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
6922 63 for version mismatches.
6924 2003-05-23 Akim Demaille <akim@epita.fr>
6926 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
6927 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
6928 the middle of a line).
6929 * lib/m4sugar/m4sugar.m4: Likewise.
6930 Remove useless spaces in comments.
6932 2003-05-23 Akim Demaille <akim@epita.fr>
6934 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
6935 exit 63, so that we (or Automake's "missing") can tell the
6936 difference with a plain failure.
6937 * doc/autoconf.texi (Notices): Adjust.
6939 2003-05-23 Akim Demaille <akim@epita.fr>
6941 * Makefile.am, bin/Makefile.am, config/Makefile.am,
6942 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
6943 White spaces cleanup.
6945 2003-05-22 Jim Meyering <jim@meyering.net>
6946 Paul Eggert <eggert@twinsun.com>
6948 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6949 Remove `#include <stdlib.h>' from the list; we should never
6950 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6951 resulting namespace pollution would cause other tests to fail.
6952 Configure scripts run with some older versions of g++ and HP's
6953 aCC would fail due to such an #include. Problems reported by
6954 Matthew Mueller in <http://bugs.debian.org/120704> and by
6955 Keith Bostic in
6956 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6957 In the test, use the test declaration before including <stdlib.h>,
6958 as that's closer to how it'll be used.
6960 2003-05-23 Akim Demaille <akim@epita.fr>
6962 * doc/autoconf.texi (Header Portability): ucred.h.
6963 From Ian Redfern.
6965 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6967 Overhaul Autotest's logging: generate separate log files
6968 in testsuite.dir/NNN/testsuite.log, and append them to
6969 testsuite.log instead of re-running the test verbosely.
6971 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6972 file descriptor, write 0 to at_status_file instead of setting
6973 at_status=0, initialize some new variables (at_status_file,
6974 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6975 to rerun the tests, instead append the at_group_log to the
6976 at_suite_log when a test fails.
6977 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6978 with the AS_MESSAGE_LOG_FD redirected to stdout.
6979 (AT_CLEANUP): save the output status in $at_status_file
6980 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6981 its original place.
6982 (AT_CHECK): since tests are run with a redirected stdout,
6983 and used to be re-run in verbose mode, turn some $at_verbose
6984 into echo, and don't redirect the output of testing stdout
6985 and stderr.
6987 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6988 the name of the debugging directory and information about
6989 its contents.
6991 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6993 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
6994 parameter.
6996 2003-05-22 Akim Demaille <akim@epita.fr>
6998 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4

7000 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

7060 2003-05-17 Akim Demaille <akim@epita.fr>
7062 * lib/autoconf/functions.m4: Use the default includes so that
7063 memcmp be declared before being tested.
7064 Reported by Sander Niemeijer.
7065 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
7066 * doc/autoconf.texi (Default Includes): Document
7067 AC_INCLUDES_DEFAULT.
7069 2003-05-17 Akim Demaille <akim@epita.fr>
7071 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
7072 * doc/autoconf.texi (Obsolete Macros): Adjust.
7073 Reported by Werner LEMBERG and Debian Bug 190886.

7106 and truncate.
7108 2003-05-06 Akim Demaille <akim@epita.fr>
7110 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7111 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7112 by aclocal.m4 is changed it might require the importing of another
7113 m4 extension file, i.e., aclocal must be run.
7115 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7116 (&parse_args): Use --force with aclocal if required and supported.
7117 (&autoreconf_current_directory): Use &run_aclocal.

7123 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
7124 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7125 argument instead of a file name, so that the request file remains
7126 open during the whole autom4te run.
7127 ($icache_file): New.
7128 (&freeze): Lock the $icache_file.
7130 2003-04-29 Derek Price <derek@ximbiot.com>
7132 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7133 seperator with m4_append_uniq(). It doesn't work.
7134 (AT_CLEANUP): Add `;' to end of at_help_all.
7135 (AT_INIT): Allow --keywords to be specified more than once. When
7136 grepping $at_help_all for keywords, use the field and keyword
7137 seperators to ensure a complete keyword match. Alter at_prev handling
7138 to support the new --keywords behavior.
7140 2003-04-27 Karl Berry <karl@freefriends.org>
7142 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7143 align better with others. I also made some of the individual
7144 entries on one line, for brevity and to make it easier for me to
7145 sort my dir-example file in the Texinfo distribution :).
7147 2003-04-12 Jim Meyering <jim@meyering.net>
7149 * NEWS: Mention the new macro.
7150 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.

7185 New.
7186 Use them.

7188 (TEXI2DVI): Make it --batch.
7190 2003-03-31 Derek Price <derek@ximbiot.com>
7192 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
7193 which removed the main loop.
7194 Thanks to Akim Demaille.
7196 2003-03-29 Akim Demaille <akim@epita.fr>

7199 that starts a GUI.
7200 From Ilya Zakharevich.
7202 2003-03-29 Akim Demaille <akim@epita.fr>
7204 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
7205 documentation to read is Autoconf's.
7206 Suggested by Paul Eggert.
7208 2003-03-28 Akim Demaille <akim@epita.fr>
7210 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
7211 reading the section "Present But Cannot Be Compiled" when the
7212 header causes problems.
7214 2003-03-28 Akim Demaille <akim@epita.fr>
7216 * tests/torture.at (Configuring subdirectories): Require aclocal
7217 1.4, otherwise the test fails, as it does support configure.ac.
7218 This fixes the "test 40 failed" bug reports.
7220 2003-03-28 Akim Demaille <akim@epita.fr>
7222 * doc/autoconf.texi (C Compiler): `#line' portability.
7223 From Paul Eggert and Nelson H. F. Beebe.
7225 2003-03-27 Derek Price <derek@ximbiot.com>
7227 * lib/autotest/general.m4: Eliminate main loop and reorganize test
7228 layout in order to allow scripting around test groups.
7230 2003-03-27 Derek Price <derek@ximbiot.com>
7232 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
7233 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
7234 use new diversions in preparation for accepting new arguments and

7251 sense. Verbosify the diversion definitions comment.
7253 2003-03-26 Derek Price <derek@ximbiot.com>
7255 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
7256 AS_PREPARE.

7277 file name for the m4 program, when it has an "exe" file extension.

7283 * doc/autoconf.texi (Present But Cannot Be Compiled): New.

7287 * doc/autoconf.texi (Limitations of Make): Remove the section
7288 about `$<' in inference rules, it was a bogus interpretation of
7289 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
7290 Tru64 make in the "target lookup" section.
7291 (Automake): Automake 1.5+ no longer requires special tools to be
7292 present on the developer's host.
7294 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
7296 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
7297 to a shell that can handle redirection or quoting correctly.
7298 Override SHELL with the shell detected by configure.
7299 Use of $^O suggested by Tim van Holder.

7308 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
7309 to cope with DOS-style absolute paths, when constructing
7310 ${ac_make}.
7312 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
7313 When constructing paths with IFS=:, quote the path. If we're
7314 constructing a DOS-style absolute path, we don't want to split it
7315 on the colon.
7317 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
7318 in description.
7320 2003-02-25 Pavel Roskin <proski@gnu.org>

7330 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
7332 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
7333 to fix a mismatch between example and discussion.
7335 2003-02-24 Kevin Ryde <user42@zip.com.au>
7337 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
7338 format starting with "-".
7340 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7342 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
7343 is not portable inside Makefile.
7345 2003-02-20 Akim Demaille <akim@epita.fr>
7347 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7348 compiler says yeah, but preproc says nope, compiler is right.
7349 Conversely, prompt the reader to send a bug report to the
7350 maintainers of the package, not of Autoconf.

7360 $ac_prefix_program.
7361 From Larry Jones.
7363 2002-12-23 Paul Eggert <eggert@twinsun.com>
7365 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7366 innocuous variant befor including <limits.h> or <assert.h>. This
7367 works around a bug reported by Albert Chin: HP-UX 11i
7368 (and earlier versions) have a <limits.h> that declares
7369 gettimeofday and many other functions.
7371 2002-12-03 Paul Eggert <eggert@twinsun.com>
7373 Version 2.57.
7375 * NEWS, configure.ac: Update version.
7377 * doc/fdl.texi: Upgrade to FDL version 1.2.
7379 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7380 nontrivially in main's body, so that f's external declaration is
7381 not optimized away in AIX. This should fix the bug reported by
7382 Martin Frydl in
7383 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7385 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7386 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7387 defined, to support freestanding compilers. This should fix the
7388 bug reported by Momchil Velkov in
7389 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7391 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7392 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

7404 \(.*\) match is too long and there is something more to be checked.
7405 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
7407 2002-11-15 Akim Demaille <akim@epita.fr>

7413 * config/move-if-change: Indenting changes.
7414 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
7415 * configure.ac (AM_INIT_AUTOMAKE): here.
7416 Require 1.7.1.
7418 2002-11-14 Akim Demaille <akim@epita.fr>
7420 Version 2.55.
7422 * config/config.guess, config/config.sub, config/install-sh:
7423 Update from masters.
7425 2002-11-14 Akim Demaille <akim@epita.fr>
7427 * Makefile.maint: Sync with Bison, i.e.:
7428 (po-check): Scan .l and .y files instead of the
7429 .c and the .h files that they generate. This fixes the bug
7430 reported by Tim Van Holder in:
7431 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7432 Look for N_ as well as for _. Try to avoid matching #define for
7433 N_ and _.
7434 From Paul Eggert.
7436 2002-11-14 Akim Demaille <akim@epita.fr>
7438 * doc/autoconf.texi (C Compiler): Compiling several files at once.
7439 From Paul Eggert and Albert Chin-A-Young.
7441 2002-11-14 Akim Demaille <akim@epita.fr>
7443 * doc/autoconf.texi (C Compiler): Solitary backslashes.
7444 From Paul Eggert and Albert Chin-A-Young.
7446 2002-11-14 Kevin Ryde <user42@zip.com.au>
7448 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
7449 than assigning in main, to avoid HP cc +O3 optimizing it away.
7451 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
7453 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
7454 option. Process --recheck after parsing all options. Pass -q
7455 option to configure on --recheck.
7456 (AC_OUTPUT): Pass -q from configure to config.status.
7457 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
7458 arguments to record.
7459 * doc/autoconf.texi (config.status Invocation): Document
7460 config.status -q option.
7462 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
7464 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
7465 Makefile.in if Makefile.am exists.
7466 (output): Strip `.am' from Makefiles. Don't
7467 output AC_CONFIG_FILES if no Makefiles were found.
7469 2002-11-07 Akim Demaille <akim@epita.fr>
7471 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.

7484 * tests/torture.at (Configuring subdirectories): Don't use grep
7485 -w.
7486 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
7487 Reported by Ezra Peisach.
7489 2002-11-05 Akim Demaille <akim@epita.fr>
7491 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7492 Remove.
7493 We _have_ to stop using the old compatibility scheme that tried to
7494 avoid useless backslashes because Libtool 1.4.3 contains a
7495 AC_DEFINE([error_t], [int],
7496 [Define to a type to use for \`error_t' if it is not
7497 otherwise available.])
7498 We _have_ to quote the single quote and backslashes with \. The
7499 old compatibility scheme saw that ` was backslashed, and therefore
7500 did not quote the single quote. Hence before this patch, Autoconf
7501 was not compatible with Libtool.
7503 2002-11-04 Paul Eggert <eggert@twinsun.com>
7505 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
7506 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
7507 LC_NAME, LC_PAPER, LC_TELEPHONE.

7512 Version 2.54c.
7514 * Makefile.maint (update, cvs-update, po-update, do-po-update):

7520 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
7521 from...
7522 (&autoreconf): here.
7523 ($help, $make, &parse_args, &autoreconf_current_directory):
7524 Support -m/--make.
7525 * doc/autoconf.texi (autoreconf Invocation): Adjust.

7541 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
7543 2002-10-31 Akim Demaille <akim@epita.fr>
7545 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
7546 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
7547 Make variable, not a shell variable.
7548 Suggested by Bruno Haible.
7550 2002-10-31 Akim Demaille <akim@epita.fr>
7552 * bin/autom4te.in (load_configuration): Reject #args out of any
7553 language.
7555 2002-10-31 Akim Demaille <akim@epita.fr>
7557 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.

7569 Suggested by Tim van Holder.
7571 2002-10-29 Paul Eggert <eggert@twinsun.com>
7573 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
7574 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
7575 Problem reported by Bruno Haible.
7577 2002-10-29 Akim Demaille <akim@epita.fr>
7579 * doc/autoconf.texi (Header Templates): Put also in words what the
7580 pictures says to assist free style readers.
7581 (Customizing autom4te): s/--cache=/--cache /.
7583 2002-10-29 Akim Demaille <akim@epita.fr>
7585 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
7586 sys/wait.h.

7589 From Bruno Haible.
7591 2002-10-29 Akim Demaille <akim@epita.fr>

7830 * doc/autoconf.texi (Limitations of Usual Tools): Remove incorrect
7831 words about HP-UX cmp: it was actually a user-written cmp.
7833 2002-10-22 Akim Demaille <akim@epita.fr>
7835 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
7836 are a few warnings.
7837 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
7838 Quote for Perl '' strings, not "".
7839 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
7840 strings.
7842 2002-10-22 Akim Demaille <akim@epita.fr>
7844 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
7845 characters is a syntax warning now.

7847 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):

7852 `@', to tickle Perl's lists.
7853 Reported by Carlos Velasco.
7855 2002-10-18 Akim Demaille <akim@epita.fr>
7857 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that
7858 missing included files _are_ errors.
7859 Thanks to Alexandre Duret-Lutz.
7860 * tests/tools.at (autom4te cache): Adjust.
7861 * tests/atspecific.m4 (AT_CHECK_AUTOM4TE): New.

7867 2002-10-17 Akim Demaille <akim@epita.fr>
7869 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
7870 Fixes the `AC_ARG_VAR' test failures.
7871 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
7872 * lib/freeze.mk (check-forbidden-patterns): New.

7890 Because of caching, some files that no longer exist and are no
7891 longer required can still cause errors.
7892 Reported by Alexandre Duret-Lutz.
7894 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
7895 to frozen files in @ARGV, as @ARGV must remain being a list of
7896 files. Rather, at M4 call sites, use this...
7897 (&files_to_options): New function.
7898 (&freeze): Use &error.
7899 (&up_to_date): If a file that was included according to the cache
7900 is no longer there, then the output is out dated.
7901 (&main): Don't even check whether a file is up to date is anyway
7902 --force is given.
7903 * tests/tools.at (autom4te cache): New.
7905 2002-10-16 Akim Demaille <akim@epita.fr>
7907 * bin/autoconf.as: Kill dead options.
7908 * bin/autoupdate.in (&parse_args): Kill old options.
7909 * bin/autoreconf.in (&parse_args): Remove dead options.
7910 Factor some code.
7911 (&autoreconf): Report the directories we enter *and leave*, so
7912 that error messages can be easily located, and use GNU Make
7913 format, so that Emacs' compile mode understands us.
7914 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
7915 if some file was changed instead of `print'.
7916 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
7917 (&parse_args): Remove the dead options.
7918 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
7919 autoheader's quiet mode.

7924 2002-10-11 Akim Demaille <akim@epita.fr>
7926 No longer use CPP to check for the existing of headers: use CC to
7927 check for compilability.
7929 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
7930 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

7932 (AC_CHECK_HEADER): this.
7934 * lib/autotest/general.m4 (AT_INIT): Include the failed test
7935 numbers in the Subject suggestion.

7949 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
7950 file name to enable parallel executions.
7951 From Sam Varshavchik.
7953 2002-10-08 Akim Demaille <akim@epita.fr>
7955 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7956 aclocal invocation, as Gettext macros might not be visible to
7957 aclocal.
7958 Instead of blindly running autopoint, scan configure.ac (not the
7959 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
7960 Reported by Paul D. Smith.
7962 2002-10-08 Paul Eggert <eggert@twinsun.com>
7964 Work around problems found when POSIXLY_CORRECT=1 is set.
7965 None of this seems to have anything to do with POSIX, really,
7966 but it's how Perl getopt works.
7967 * bin/autom4te.in (parse_args): Configure GetOpt with
7968 "permute", too.
7969 * doc/autoconf.texi (Invoking autom4te):
7970 --warning -> --warnings.
7971 * lib/autom4te.in: --warning -> --warnings.
7973 2002-09-28 Akim Demaille <akim@epita.fr>

7990 2002-09-28 Akim Demaille <akim@epita.fr>
7992 * tests/torture.at (Configuring subdirectories): Be robust to
7993 users who use config.site to require for a cache: in this case,
7994 the two last configure runs, using two different sets of
7995 arguments, trigger a legitimate error.
7997 2002-09-28 Akim Demaille <akim@epita.fr>
7999 * tests/m4sh.at (Functions Support, Functions and return Support):
8000 New.

8013 (tm_zone): Move their rules to...
8014 * lib/autoconf/types.m4: here, using AN_ macros.
8015 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8016 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8017 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
8018 * lib/autoconf/programs.m4: here.

8030 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8031 (.m4.m4f): Don't pass --prepend-include, since that's done by
8032 tests/autom4te itself.
8033 * lib/autoscan/Makefile.am: Include freeze.mk.
8034 (autoscan.list): New target --this file is no longer a source.
8035 (autoscan.pre): New file.
8037 2002-09-28 Akim Demaille <akim@epita.fr>
8039 * bin/autoscan.in (@kinds): Make them singular.
8040 Adjust all uses.
8041 (&init_tables): When --debug, report the list of rules to ease
8042 tracking changes in autoscan.list.
8043 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8045 2002-09-28 Akim Demaille <akim@epita.fr>

8056 * lib/autoscan/identifiers, lib/autoscan/makevars,
8057 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8058 `functions' line is now prefixed with `function:'.
8059 * bin/autoscan.in (&init_tables): Adjust.
8061 2002-09-28 Akim Demaille <akim@epita.fr>
8063 From now on, autoscan files must always map a macro name to a
8064 word: there is no `default' macro for autoscan.
8066 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8067 all.
8068 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8069 explicit.
8071 2002-09-28 Akim Demaille <akim@epita.fr>
8073 * bin/autoscan.in (%c_keywords): Remove.
8074 (&used): Keep only track of the words we might be interested in.

8106 Reported by Ralf Corsepius.
8107 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8109 2002-09-26 Akim Demaille <akim@epita.fr>
8111 Single suffix rules and seperated dependencies are not portable.
8113 * doc/autoconf.texi (Installation Directory Variables): Update.
8114 (Limitations of Make): Some about `Single Suffix Rules and

8133 2002-09-16 Akim Demaille <akim@epita.fr>
8135 i960 compilers create `b.out' files by default.
8136 Reported by Ralf Corsepius.
8138 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.

8157 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8158 reading config.log when the compiler is rejected.
8159 Suggested by Guido Draheim.
8161 2002-09-13 Akim Demaille <akim@epita.fr>
8163 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8164 (chdir_init) might hang when stat'ing mounted directories.
8165 Reported by Vance Shipley.
8167 2002-09-12 Akim Demaille <akim@epita.fr>
8169 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8170 the lists.
8172 2002-09-12 Akim Demaille <akim@epita.fr>
8174 * doc/autoconf.texi (Defining Symbols): Present two different
8175 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the

8180 * doc/autoconf.texi: Review grammar and punctuation.

8185 grammatical typos.
8186 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8187 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8188 is obsolescent.
8190 2002-09-11 Akim Demaille <akim@epita.fr>
8192 * doc/autoconf.texi (Questions): Rename as...
8193 (FAQ): this.

8208 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8209 `duplicates', since the algorithm was too naive and could keep
8210 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8211 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8212 Reported by Ralf Corsepius.
8213 * tests/torture.at (Configuring subdirectories): Exercise these
8214 cases.
8216 2002-09-09 Akim Demaille <akim@epita.fr>

8219 looking for a replacement file.
8220 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8221 directory is relative.
8222 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8223 directory definition.
8224 Reported by Andreas Schwab and Jim Meyering.
8226 2002-09-06 Akim Demaille <akim@epita.fr>

8229 precious variables are.
8230 Suggested by Pontus Skoeld.
8232 2002-09-05 Akim Demaille <akim@epita.fr>
8234 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8235 (ifnames, autoscan, autom4te): Since we don't only depend on
8236 configure.ac variables (such as VERSION etc.), but also on prefix
8237 and so forth, depend on Makefile, not configure.ac.
8238 Reported by Alexandre Duret-Lutz.
8239 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8241 2002-09-05 Kevin Ryde <user42@zip.com.au>
8243 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8244 doesn't seem to be confined to ia64, just say "some versions".
8246 2002-09-04 Akim Demaille <akim@epita.fr>
8248 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by

8261 * configure.ac: Bump to 2.53d.
8262 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8263 as of today, on Automake's team suggestion.
8265 2002-09-03 Akim Demaille <akim@epita.fr>
8267 Version 2.53c.
8269 2002-09-02 Akim Demaille <akim@epita.fr>
8271 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8272 SITE_MACRO_DIR.
8273 * configure.ac: Disable SITE_MACRO_DIR.
8275 2002-09-02 Jim Meyering <meyering@lucent.com>
8277 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8278 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8279 Also, tweak grammar: s/make sure to/be sure to/.
8281 2002-09-02 Paul Eggert <eggert@twinsun.com>
8283 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8284 directory names are generally preferable to physical names.
8286 2002-09-02 Akim Demaille <akim@epita.fr>
8288 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8289 Reported by Raja R. Harinath.
8290 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8291 * bin/autoupdate.in: Use error instead of die.
8293 2002-09-01 Paul Eggert <eggert@twinsun.com>
8295 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8296 ordinary shell concatenation rather than echo+tr+sed command that
8297 runs afoul of a long-line-related sed bug in Solaris 8.
8299 * bin/autoheader.in (parse_args): --warning -> --warnings.
8301 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8302 stdout, as traditional "ls" does.
8303 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8304 _AC_COMPILER_EXEEXT_O): Likewise.
8305 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8307 * bin/autoconf.as: Add --prepend-include option. This patch was
8308 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8309 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8311 * bin/autoconf.in, configure: Regenerate.
8313 * doc/autoconf.texi (Special Shell Variables): Mention
8314 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8316 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8317 MAILPATH and set PS1, PS2, PS4 to default values, to work
8318 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8319 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8320 the Autoconf documentation specifies; fall back to "unset" only if
8321 this fails. Use a shell for-loop for this rather than an m4 loop,
8322 to shorten the output script.
8324 2002-08-30 Paul Eggert <eggert@twinsun.com>
8326 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8327 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8328 for the CDPATH problem. Document PWD.
8329 (Limitations of Builtins): Document the problem that "cd $foo" and
8330 "ls $foo" may refer to different directories in shells conforming
8331 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8332 example, since the old example is now out of date.
8334 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8335 FOO" and "ls FOO" talk about different directories; this catches
8336 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8337 spaghetti.
8339 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8340 of rolling our own unset.
8341 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8342 in practice we needn't worry about CDPATH if unset doesn't work.
8344 * Makefile.in, aclocal.m4, bin/Makefile.in,
8345 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8346 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8347 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8348 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8349 tests/Makefile.in: Regenerate with Automake 1.6.3.
8351 * config/config.guess, config/config.sub, config/mkinstalldirs:
8352 Update.
8354 * configure: Regenerate with self.
8356 2002-08-30 Kevin Ryde <user42@zip.com.au>
8358 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8359 default output.
8361 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8363 * bin/autom4te.in (Request::load): Correctly test for "do" read
8364 failure.
8366 2002-08-29 Akim Demaille <akim@epita.fr>
8368 * lib/Autom4te/General.pm (&xqx): New.
8369 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8370 hand, which is not portable.
8371 (&error): New.
8372 * bin/autom4te.in: Use them.
8373 Use &error instead of die.
8374 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8375 Adjust.
8377 2002-08-17 Paul Eggert <eggert@twinsun.com>
8379 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8380 default list of compilers to try, since it was long ago superseded
8381 by the ksh fc builtin. Suggested by Steven G. Johnson.
8383 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8385 * doc/autoconf.texi (Invoking autom4te): End the option table,
8386 fixing a bug introduced by the previous patch.
8387 (Limitations of Make): Add a 'target lookup' subentry in the
8388 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8390 2002-07-29 Mark D. Roth <roth@feep.net>
8392 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8393 options and use $AUTOM4TE_PATH.
8394 * doc/autoconf.texi: Remove documentation of autom4te
8395 --include-envvar and --site-macro-subdir options and document
8396 use of $AUTOM4TE_PATH.
8397 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8398 arguments from each language section.
8400 2002-07-29 Paul Eggert <eggert@twinsun.com>
8402 * doc/install.texi: Include copyright symbol in copyright notice.
8404 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8405 Replace with:
8406 (AM_MAKEINFOFLAGS): New macro.
8407 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8408 * Makefile.am (INSTALL): Use the new macros.
8409 Use -o rather than --output, since "missing" does not grok --output.
8411 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8413 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8414 comments do not always work. Never trust the exit status of
8415 `make -k'.
8417 2002-07-24 Kevin Ryde <user42@zip.com.au>
8419 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8420 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8422 2002-07-23 Paul Eggert <eggert@twinsun.com>
8424 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8425 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8426 apparently treats PATH="nonexistent" as if it contained ".".
8427 Bug reported by Stefan `Sec' Zehl.
8429 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8431 * doc/autoconf.texi (Limitations of Make): Mention the special
8432 handling of the obj/ directory by BSD make.
8434 2002-07-20 Kevin Ryde <user42@zip.com.au>

8448 2002-07-18 Akim Demaille <akim@epita.fr>
8450 Version 2.53b.
8452 2002-07-18 Akim Demaille <akim@epita.fr>
8454 * config/config.guess, config/config.sub: Update.
8456 2002-07-18 Akim Demaille <akim@epita.fr>
8458 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
8459 Automake's parts.
8461 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
8462 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
8463 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
8465 2002-07-18 Akim Demaille <akim@epita.fr>,
8466 Alexandre Duret-Lutz <duret_g@epita.fr>
8468 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
8469 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

8478 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
8479 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
8480 latter was not run.
8482 2002-07-17 Akim Demaille <akim@epita.fr>
8484 * lib/Autom4te/General.pm (find_file): Browse the directories in
8485 the order they are given.

8505 macro directory, remove note that include path directories are
8506 used in reverse order, and document --prepend-include option.
8507 * lib/autom4te.in: Use --prepend-include instead of --include.
8508 * tests/wrapsh.in: Use --prepend-include instead of --include.

8546 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
8548 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
8549 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
8550 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
8551 so that Emacs setups GNU style for perl-mode and cperl-mode.
8553 2002-06-27 Paul Eggert <eggert@twinsun.com>
8555 * config/install-sh: Quote $src. Prefer || to test's -o option,
8556 as per "Limitations of Builtins".
8557 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
8558 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
8560 * tests/mktests.sh: Use grep instead of fgrep, as per
8561 "Limitations of Builtins".
8563 2002-06-15 Paul Eggert <eggert@twinsun.com>
8565 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
8566 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
8567 so that we consistently test the just-built programs.
8568 * tests/wrappl.as: Likewise.
8570 2002-06-12 Paul Eggert <eggert@twinsun.com>
8572 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
8573 name, so that symlinks to 'autoconf' work properly. Bug reported
8574 by Bruno Haible.
8575 * bin/autoheader.in (AUTOM4TE): Likewise.
8576 * bin/autoreconf.in (autoconf, autoheader): Likewise.
8577 * bin/autoscan.in (autom4te): Likewise.
8578 * bin/autoupdate.in (autom4te): Likewise.
8580 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
8581 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
8582 on Solaris 2.5.1.
8584 2002-06-11 Andreas Schwab <schwab@suse.de>
8586 * doc/autoconf.texi: Add more dir entries.
8588 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
8590 * bin/autom4te.in ($cache): Don't define using `$me', the name
8591 of the cache should not depend on the name under which autom4te
8592 was installed.
8594 2002-06-07 Akim Demaille <akim@epita.fr>
8596 * tests/tools.at (autoconf: forbidden tokens, basic)
8597 (autoconf: forbidden tokens, exceptions): Adjust to the change of
8598 words in autom4te.in.
8600 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
8602 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
8603 _AC_LANG_PROGRAM_C_F77_HOOKS.
8605 2002-06-07 Akim Demaille <akim@epita.fr>
8607 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
8608 rename as...
8609 (AC_REPLACE_FNMATCH): this.
8610 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
8611 AC_FUNC_FNMATCH_GNU.
8613 2002-06-07 Akim Demaille <akim@epita.fr>
8615 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
8616 Rosetta Stone for Unix.
8618 2002-06-07 Akim Demaille <akim@epita.fr>
8620 * bin/autom4te.in (warn_forbidden): When rejecting a token,
8621 suggest m4_pattern_allow.
8622 Suggested by Adam J. Richter.
8624 2002-06-07 Akim Demaille <akim@epita.fr>
8626 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
8627 ac_config_libobj_dir.
8628 (AC_CONFIG_LIBOBJ_DIR): New.
8629 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
8630 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
8631 Use ac_config_libobj_dir to find the replacement files.
8632 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
8633 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
8634 (AC_REPLACE_FNMATCH_GNU): these.
8635 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
8636 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
8637 * tests/mktests.sh (ac_exclude_list): Don't check
8638 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
8640 2002-06-06 Paul Eggert <eggert@twinsun.com>
8642 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
8643 if ln doesn't work.
8644 * NEWS: Likewise.
8645 * doc/autoconf.texi (Configuration Links): Likewise.
8646 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
8648 2002-06-05 Paul Eggert <eggert@twinsun.com>
8650 * config/config.guess, config/config.sub, config/texinfo.tex:
8651 Update from masters.
8653 2002-05-29 Paul Eggert <eggert@twinsun.com>
8655 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
8656 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
8657 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):

8665 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
8666 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
8668 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
8669 * doc/autoconf.texi (Particular Programs): Document them.
8670 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
8671 * NEWS: Likewise.
8673 2002-05-27 Paul Eggert <eggert@twinsun.com>
8675 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
8676 * NEWS, doc/autoconf.texi (Particular Types): Document it.
8677 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
8678 instead of AC_MBSTATE_T, which never existed.
8680 2002-05-23 Akim Demaille <akim@epita.fr>
8682 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
8683 version of Autoconf that is discussed.
8685 2002-05-22 Paul Eggert <eggert@twinsun.com>
8687 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
8688 from the default list of compilers to try. Suggested by
8689 Kate Hedstrom.
8690 * NEWS: Document the above.
8691 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
8693 2002-05-17 Paul Eggert <eggert@twinsun.com>
8695 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
8696 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
8697 This improves on an earlier suggestion by H. Peter Anvin.
8699 2002-05-16 Paul Eggert <eggert@twinsun.com>
8701 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
8702 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
8703 Both macros now accept an optional source-dir arg.
8704 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
8706 * NEWS: Document this.
8707 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
8709 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
8710 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
8711 not for GNU extensions; this undoes part of the 2000-11-03 change,
8712 reverting to 2.13-compatible behavior.
8713 Add new optional argument DIR.
8714 (AC_FUNC_FNMATCH_GNU): New macro.
8716 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
8718 2002-05-08 Paul Eggert <eggert@twinsun.com>
8720 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
8721 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
8722 and it causes a 'test' syntax error if it fails.
8723 Bug reported by Stephen Gildea.
8725 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8726 If prototypes are supported, use them to check this at compile-time,
8727 instead of trying to check it at run-time. If we must do a run-time
8728 check, assume that setvbuf is standard when cross-compiling, as
8729 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8730 Bug reported by Paul D. Smith.
8732 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8733 argument specifying location of getloadavg.c. This removes a
8734 FIXME. This idea was taken from Jim Meyering's implementation in
8735 textutils.
8736 * doc/autoconf.texi (Particular Functions): Document this.
8737 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8738 that's what the code does; this fixes a bug reported by
8739 Paul D. Smith.
8741 2002-05-03 Akim Demaille <akim@epita.fr>
8743 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8744 autopoint instead of gettextize.
8745 ($uses_alocal): Rename as...
8746 ($uses_aclocal): this.
8747 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8748 Suggested by Bruno Haible.
8750 2002-05-03 Akim Demaille <akim@epita.fr>
8752 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
8754 2002-04-29 Paul Eggert <eggert@twinsun.com>
8756 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
8757 files to be 1 second older; just set them to be the same time.
8758 Also, sleep 1 second after the first aclocal, to work around
8759 problems with sub-second time stamps on the input files.
8761 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
8763 * doc/autoconf.texi: Mention "set -e -x" lossage
8764 under node "Limitations of Builtins".
8766 2002-04-29 Akim Demaille <akim@epita.fr>
8768 * doc/install.texi: Better wording for setting variables when
8769 running configure.
8770 From Christian Cornelssen.
8772 2002-04-29 Akim Demaille <akim@epita.fr>
8774 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
8775 of lack of $LINENO support, then the test will compare the $LINENO
8776 in testsuite vs. the lineno in the test file. This is wrong, of
8777 course.
8778 Be sure to protect it.
8779 Reported by Patrick Welche.
8781 2002-04-25 Akim Demaille <akim@epita.fr>
8783 * doc/autoconf.texi (Obsolete Macros): Typo.
8784 Reported by Vladimir Volovich.
8786 2002-04-25 Akim Demaille <akim@epita.fr>
8788 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
8789 than some of the input files, hence, on the second run of aclocal,
8790 if some of its input are younger, make them older.
8791 Suggested by Paul Eggert.
8793 2002-04-25 Akim Demaille <akim@epita.fr>
8795 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
8796 Thanks to Paul Eggert.
8798 2002-04-25 Akim Demaille <akim@epita.fr>
8800 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
8801 and ac_subst_vars be sh variables containing the list of
8802 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
8803 DEFAULT diversion.
8804 (_AC_INIT_PREPARE): Use them to log them.
8805 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
8806 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
8807 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
8808 _AC_SUBST_FILES and _AC_SUBST_VARS.
8809 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
8811 2002-04-24 Akim Demaille <akim@epita.fr>
8813 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
8814 autoheader, so that automake does not complain about a missing
8815 config.h.in that was to be created.
8817 2002-04-23 Akim Demaille <akim@epita.fr>
8819 * bin/autoheader.in (parse_args): --warning takes an argument.
8820 Fixes PR/220.

8824 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
8825 and bb.out when cleaning up.

8833 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
8835 2002-04-22 Akim Demaille <akim@epita.fr>
8837 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
8838 comma.
8839 Reported by Gregory Giannoni.
8841 2002-04-22 Akim Demaille <akim@epita.fr>
8843 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.

8868 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
8869 Minor spelling and grammar fixes.
8871 * doc/autoconf.texi: Follow the outline suggested in the GNU
8872 Sample Texts sections of the Texinfo 4.2 manual. Most
8873 importantly, this makes sure that the copyright notices appear in
8874 all output formats. You probably need Texinfo 4.2 to generate
8875 the manual now.
8877 Fix some bugs when using "$@" when there might be zero positional
8878 arguments in cases where this matters.

8899 that is not portable to Zsh.
8901 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
8903 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
8904 from aclocal.m4 too.
8906 2002-04-12 Akim Demaille <akim@epita.fr>
8908 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
8910 2002-04-10 Akim Demaille <akim@epita.fr>
8912 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
8913 workaround for ${1+"$@"}.
8914 * doc/autoconf.texi (Shell Substitutions): Explain it.
8915 From Oliver Kiddle and Peter Stephenson.
8917 Have M4sh perform minimal shell sanitizing.
8919 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
8920 part into...
8921 (_AS_PREPARE): this new macro.
8922 (AS_PREPARE): New.
8923 (AS_INIT): Invoke AS_SHELL_SANITIZE.
8924 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
8926 Adjust Autoconf and Autotest.
8928 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
8929 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
8930 * lib/autotest/general.m4 (AT_INIT): Likewise.
8931 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8932 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
8933 AS_SHELL_SANITIZE.
8935 Use this M4sh to generate Autoconf's shell scripts.
8937 * tests/wrapsh.as: New, precursor of wrapsh.in.
8938 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
8939 on Autotest and M4sh.
8940 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
8941 (wrapsh.in): New target.
8942 * bin/autoconf.as: New, precursor of autoconf.in.
8943 (autoconf.in): New target.
8945 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

8948 with indented comments in rules.
8950 2002-04-09 Andreas Schwab <schwab@suse.de>
8952 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
8953 ac_top_builddir when setting ac_abs_top_builddir.
8955 2002-04-06 Kevin Ryde <user42@zip.com.au>
8957 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
8958 (Portable Shell): Cross reference to Systemology.
8960 2002-04-05 Akim Demaille <akim@epita.fr>
8962 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
8963 directories when descending in a SUBDIRS.
8964 Reported by Ezra Peisach.
8966 2002-04-04 Andreas Schwab <schwab@suse.de>
8968 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
8969 contains no literal separators.
8971 2002-04-03 Akim Demaille <akim@epita.fr>
8973 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
8974 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
8975 Use dnl, not the KILL diversion.
8976 Extracted from...
8977 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8978 (AC_CONFIG_LINKS): here.
8979 Adjust.
8980 Don't use the KILL diversion, as it kills spurious output, which
8981 results in failures being hidden.
8982 Use m4_defn where appropriate.
8983 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8984 after the second argument.
8985 Use m4_defn.
8986 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8987 syntax, as it is provided by M4sugar.
8988 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
8990 2002-04-03 Andreas Schwab <schwab@suse.de>
8992 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not

8996 aclocal.

9002 Also recognize *.bb and *.bbg as compilation byproducts.
9003 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9004 (_AC_COMPILER_OBJEXT): Use them.
9005 Fixes Debian #138666.
9007 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9009 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
9011 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
9012 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9013 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9014 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9015 (AC_C_CONST): Same.

9020 AC_C_CROSS.

9025 _AS_MKDIR_P_PREPARE.
9027 2002-03-28 Kevin Ryde <user42@zip.com.au>
9029 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9030 to avoid versions of HP C which don't allow that.
9032 2002-03-27 Paul Eggert <eggert@twinsun.com>
9034 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9035 (AS_SHELL_SANITIZE): Invoke it.
9036 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9038 2002-03-26 Akim Demaille <akim@epita.fr>
9040 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9042 2002-03-26 Akim Demaille <akim@epita.fr>
9044 * doc/autoconf.texi (Introduction): The GNATS base moved.
9046 2002-03-25 Paul Eggert <eggert@twinsun.com>
9048 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9049 as POSIX requires, as it doesn't work with Zsh.
9050 * doc/autoconf.texi (Assignments): Document the problem.
9052 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9054 * doc/autoconf.texi (Limitations of Make): Mention more issue
9055 about VPATH, overriding of macros in sub-makes, and handling of
9056 SHELL.
9058 2002-03-21 Paul Eggert <eggert@twinsun.com>
9060 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9061 problem with here-document buffer boundaries.
9063 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9064 when reinvoking the shell, to work around problems with installers
9065 who put strange things like "cd" commands in their environments.
9067 2002-03-19 Akim Demaille <akim@epita.fr>
9069 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9070 From Aaron Ucko.
9072 2002-03-19 Akim Demaille <akim@epita.fr>

9080 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9081 From Nishio Futoshi.
9083 2002-03-19 Akim Demaille <akim@epita.fr>
9085 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9087 2002-03-18 Paul Eggert <eggert@twinsun.com>
9089 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9090 (Limitations of Usual Tools): Add mkdir section.
9092 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9093 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9094 back on AS_DIRNAME to compute prefixes otherwise; this is
9095 roughly what mkinstalldirs does. That way, we need not have
9096 our own filename disassembler. The old disassembler did not
9097 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9099 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9100 Create at_test_all by a series of assignments,
9101 not by a single assignment of a long string. The latter causes ksh
9102 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9103 presumably because of a buffer overrun.
9105 2002-03-14 Paul Eggert <eggert@twinsun.com>
9107 * lib/autotest/general.m4 (at_times_skip):
9108 Renamed from at_times. Now a boolean.
9109 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9110 says 'times: not found'.
9112 2002-03-14 Akim Demaille <akim@epita.fr>
9114 * bin/autoreconf.in (&study_gettextize): New.
9115 (&autoreconf): Handle newest gettextize.

9125 * doc/autoconf.texi (Header Portability): New.
9126 Add information about stdint.h and inttypes.h from Paul Eggert.
9128 2002-03-13 Akim Demaille <akim@epita.fr>
9130 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9131 -p'.
9132 From Bob Proulx.
9134 2002-03-12 Akim Demaille <akim@epita.fr>
9136 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9137 m4_require.
9139 2002-03-11 Andreas Schwab <schwab@suse.de>
9141 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9142 does not do it if --with-lispdir is given.
9144 2002-03-08 Akim Demaille <akim@epita.fr>
9146 Version 2.53.
9148 2002-03-08 Akim Demaille <akim@epita.fr>

9151 subdirectory should exist.
9153 2002-03-08 Akim Demaille <akim@epita.fr>
9155 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9157 2002-03-08 Akim Demaille <akim@epita.fr>
9159 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9160 aliases the actual variables, and modifications of the former
9161 affect the latter.
9163 2002-03-08 Akim Demaille <akim@epita.fr>
9165 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9166 because of C-c: have m4 output in tmp files, then mv them.
9168 2002-03-08 Akim Demaille <akim@epita.fr>
9170 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9171 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
9172 * bin/ifnames.in: Copyright update.

9178 2002-03-05 Akim Demaille <akim@epita.fr>
9180 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9181 Kevin Ryde.
9183 2002-03-05 Akim Demaille <akim@epita.fr>
9185 Version 2.52i.
9187 2002-03-04 Akim Demaille <akim@epita.fr>
9189 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9190 * lib/autoconf/general.m4 (AC_INIT): More informative error
9191 message for LIBOBJ.
9193 2002-03-04 Akim Demaille <akim@epita.fr>
9195 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9196 parallel builds.
9198 2002-03-04 Akim Demaille <akim@epita.fr>
9200 * doc/autoconf.texi (Transforming Names): Equality between target
9201 and host is irrelevant.
9202 (Specifying Names, Canonicalizing): Remove all references to the
9203 backward compatibility hooks. Rather, collect them all into...
9204 (Hosts and Cross-Compilation): this new section.
9205 * doc/install.texi (System Type): Ditto.
9206 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9207 that `--host' implies cross-compilation.
9209 2002-03-04 Akim Demaille <akim@epita.fr>
9211 * doc/autoconf.texi (Evaluation Macros): New.
9212 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9213 useless.
9214 (_m4_foreach): Define the variant with immediate evaluation so
9215 that it contains exactly the items, not an expression which
9216 evaluation is the current item.
9217 (m4_re_string, m4_re_word): Don't over quote them.
9219 2002-03-04 Akim Demaille <akim@epita.fr>
9221 Instead of having stacking `shift's evaluated at the end, let
9222 `foreach' loops immediately evaluate them.
9224 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9225 $*. This is the n-th time I change my mind, but hopefully this is
9226 the last...
9227 (m4_lquote): New.
9228 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9229 efficient.
9230 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9231 it was only a hack for m4_text_wrap.
9232 (m4_car2): Remove, replaced by...
9233 (m4_cdr): New.
9234 (_m4_foreach): Adjust.
9235 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9236 m4_bpatsubst for clarification.

9280 Fix Autoconf PR/209.
9281 Also reported by Frank Denis.
9283 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
9285 2002-02-07 Akim Demaille <akim@epita.fr>
9287 Fix Autoconf PR/207:
9288 AC_PREFIX_PROGRAM fails with dashed program names
9290 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9291 variable when looking for the prefix program.
9292 Now it also works for shell variables.
9294 2002-02-07 Akim Demaille <akim@epita.fr>
9296 * doc/autoconf.texi (Limitations of Builtins): More about
9297 case/esac.
9299 2002-02-06 Akim Demaille <akim@epita.fr>
9301 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
9302 case/esac, some shells don't support it.
9303 Reported by Zack Weinberg.
9304 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
9306 2002-02-06 Akim Demaille <akim@epita.fr>
9308 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9309 sure not to introduce newlines in at_groups.
9310 * lib/autotest/Makefile.am (autotest.m4f): Typo.
9312 2002-02-06 Akim Demaille <akim@epita.fr>
9314 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9315 is not available.
9317 2002-02-05 Paul Eggert <eggert@twinsun.com>
9319 * doc/autoconf.texi (Specific Compiler Characteristics):
9320 Describe HP-UX cc bug workaround more accurately.
9321 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
9322 not unsigned long.
9323 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9324 cross-compilers, too. This undoes some of the most recent change
9325 to this file.
9327 2002-02-05 Akim Demaille <akim@epita.fr>
9329 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9330 to make sure they are up to date when `check' is run.
9332 2002-02-05 Akim Demaille <akim@epita.fr>
9334 * doc/autoconf.texi (Making testsuite Scripts): Document
9335 package.m4.
9337 2002-02-05 Akim Demaille <akim@epita.fr>
9339 * lib/freeze.mk: New.
9341 2002-02-05 Akim Demaille <akim@epita.fr>
9343 Implement `autom4te --freeze'.
9345 * bin/autom4te.in (&freeze): New.
9346 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9347 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9349 2002-02-05 Akim Demaille <akim@epita.fr>
9351 * bin/autom4te.in (&parse_args): Implement `frozen files are
9352 optional are the sum of the previous files on the command line'.
9353 Also, pass `--reload-state=' on them, so...
9354 (handle_m4): don't.
9355 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9356 (M4sh): Rely on M4sugar.
9357 (Autotest, M4sh, M4sugar): Use frozen files.
9359 2002-01-31 Akim Demaille <akim@epita.fr>
9361 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
9362 * doc/autoconf.texi (Initializing configure): Adjust.
9364 2002-01-30 Akim Demaille <akim@epita.fr>
9366 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9367 alphanumeric to `-' instead of `_'.
9369 2002-01-30 Akim Demaille <akim@epita.fr>
9371 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9372 for plain code, the other for cross-compilation code. The latter
9373 is now run with GCC only.
9374 * doc/autoconf.texi (Compilers and Preprocessors): New.
9376 2002-01-30 Akim Demaille <akim@epita.fr>
9378 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
9379 values.
9380 * doc/autoconf.texi (Initializing configure): Explain how to
9381 change AC_INIT default values.
9383 2002-01-29 Akim Demaille <akim@epita.fr>
9385 * tests/torture.at (Configuring subdirectories): Use configure.in,
9386 so that aclocal 1.4 works.
9387 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9389 2002-01-28 Akim Demaille <akim@epita.fr>
9391 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9392 needs an argument.
9394 2002-01-28 Akim Demaille <akim@epita.fr>
9396 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9397 AUTOTEST_PATH *after* it was set.
9398 Don't put `.' in the PATH: the user should be precise and `./' if
9399 needed. In addition, given that the test suite does some `cd', if
9400 `.' is in the path, the `tested programs' sections will report
9401 programs found in the test suite's directory, while during the
9402 tests (performed in their own directory), these programs are no
9403 longer visible. In other words, the results is confusing and
9404 useless.
9405 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9407 2002-01-24 Akim Demaille <akim@epita.fr>
9409 Version 2.52g.
9411 2002-01-24 Akim Demaille <akim@epita.fr>
9413 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
9414 * doc/autoconf.texi: Finally add Akim as an author.
9416 2002-01-24 Akim Demaille <akim@epita.fr>
9418 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
9419 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
9420 Bourne. Use /bin/sh.
9421 From Andreas Buening.
9423 2002-01-24 Akim Demaille <akim@epita.fr>
9425 * config/config.guess, config/config.sub, config/texinfo.tex:
9426 Update from masters.
9428 2002-01-24 Akim Demaille <akim@epita.fr>
9430 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
9431 * config/auxdir.m4, config/cond.m4, config/depend.m4,
9432 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
9433 * config/missing.m4, config/sanity.m4, config/select.m4,
9434 * config/strip.m4: Remove, to ease sync'ing with any version of
9435 Automake.
9437 2002-01-24 Akim Demaille <akim@epita.fr>
9439 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
9440 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
9441 Reported by Geir Ove Myhr.
9443 2002-01-21 Akim Demaille <akim@epita.fr>
9445 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
9447 2002-01-21 Akim Demaille <akim@epita.fr>
9449 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
9450 message on invalid options.
9451 * bin/autom4te.in (parse_args): Don't use
9452 Autoconf::General::getopt with non valid options.
9454 2002-01-17 Jim Meyering <meyering@lucent.com>
9456 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
9457 $ac_cv_exeext so we don't use an old, invalid, cached value.
9459 2002-01-11 Akim Demaille <akim@epita.fr>
9461 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
9462 Meyering.

9466 * lib/autoscan/functions: Adjust.
9468 2002-01-06 Akim Demaille <akim@epita.fr>
9470 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
9471 package.m4, since is really depends upon configure.ac, not
9472 configure.
9473 * doc/autoconf.texi (testsuite Scripts): Adjust.
9474 * tests/Makefile.am (package.m4): New.
9475 EXTRA_DIST it since its a source.
9477 2002-01-06 Akim Demaille <akim@epita.fr>
9479 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9480 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9481 and PACKAGE_BUGREPORT from here...
9482 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9483 arguments.
9484 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
9485 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
9486 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
9487 * tests/tools.at (autoheader): Adjust.
9488 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
9490 2002-01-06 Akim Demaille <akim@epita.fr>
9492 * bin/autoscan.in (scan_file): Use `&used'.
9494 2002-01-03 Akim Demaille <akim@epita.fr>
9496 * doc/autoconf.texi (Output): Improved wording regarding use of
9497 AC_OUTPUT.
9498 From Olly Betts.
9500 2001-12-18 Kevin Ryde <user42@zip.com.au>
9502 * doc/autoconf.texi (Function Portability): Add notes on sscanf
9503 sometimes needing writable input.
9505 2001-12-17 Jim Meyering <meyering@lucent.com>
9507 * doc/autoconf.texi (New Macros): Tweak wording.
9509 2001-12-14 Akim Demaille <akim@epita.fr>
9511 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9512 trailing files, don't apply `-rf' to files which might not be
9513 created by configure (core, core.*, and *.core), but just `rm -f'.
9514 Suggested by Jonathan Kamens.
9516 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9518 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
9520 2001-12-14 Akim Demaille <akim@epita.fr>
9522 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
9524 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
9526 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
9527 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
9528 abs_srcdir, top_srcpath to abs_top_srcdir.
9529 (_AC_OUTPUT_FILES): Adjust.
9530 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
9531 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
9532 * tests/wrappl.in, tests/wrapsh.in: Adjust.
9534 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
9536 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
9537 C/Fortran linking on HP/UX, by extracting the Fortran library
9538 search path from the LPATH line in the $F77 -v output.
9540 2001-12-12 Kevin Ryde <user42@zip.com.au>
9542 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
9543 forbidden file descriptors table.
9545 2001-11-26 Akim Demaille <akim@epita.fr>
9547 * bin/autoscan.in (%c_keywords): Build it at top level.
9548 Map to 1 in order to simplify its uses.
9550 2001-11-26 Akim Demaille <akim@epita.fr>
9552 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
9553 Remove $filepath, useless.
9554 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
9555 variables, they are really part of the tokens.
9556 Split the input line on spaces and then look for tokens.
9557 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9558 because of `lex$U.$(OBJEXT)'.
9559 (&scan_files): Use "@list" instead of join.
9560 * doc/Makefile.am (CLEANFILES): Add *.fns.
9562 2001-11-26 Akim Demaille <akim@epita.fr>
9564 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
9565 Remove, replaced by...
9566 * tests/wrappl.in: Be common for all the Perl executables.
9567 In particular autoscan and autoheader want -I.
9568 * configure.ac: Adjust.
9569 * lib/autoscan/headers: errno.h is portable.
9571 2001-11-26 Akim Demaille <akim@epita.fr>
9573 * bin/autoscan.in (used): New.
9574 Use it.
9576 2001-11-26 Akim Demaille <akim@epita.fr>
9578 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
9579 directives.
9580 (&scan_sh_file): Remove a duplicate pattern.
9581 (&check_configure_ac): Use long options.
9582 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
9584 2001-11-26 Akim Demaille <akim@epita.fr>
9586 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
9587 Before, having a line containing the opening of a multi line
9588 comment made the whole line be ignored.
9590 2001-11-26 Akim Demaille <akim@epita.fr>
9592 * doc/autoconf.texi (Using an Autotest Test Suite): New.
9593 (testsuite Scripts): Be one of its subsection.
9594 (Autotest Logs): New.
9596 2001-11-26 Akim Demaille <akim@epita.fr>
9598 Test groups are now run two directories deeper.
9600 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
9601 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
9602 at_top_builddir.
9603 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
9604 top_srcdir, builddir and top_builddir.
9605 Use `at_*dir' relatively to the directory containing the
9606 suite, use `*dir' when relatively to the current group dir.
9608 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
9610 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
9611 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
9612 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
9613 spelling errors.
9615 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9617 * doc/autoconf.texi (Using System Type): Add an example of `case
9618 $host' usage so people quit using `case $target' everywhere.
9620 2001-11-22 Akim Demaille <akim@epita.fr>
9622 * doc/autoconf.texi (Installation Directory Variables): Englishoes
9623 spotted by Jim Meyering.
9625 2001-11-16 Paul Eggert <eggert@twinsun.com>
9627 This patch implements a `long double' suggestion by Oliver Kiddle.
9629 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9630 static, to catch errors if the value isn't known at compile-time
9631 and the compiler supports dynamic arrays. Change its name from
9632 `_array_' to `test_array' to avoid potential name clashes.
9633 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9634 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9635 better than double. Catch a bug in GCC 2.95.2 x86.
9636 * doc/autoconf.texi (C Compiler): Document the above.
9637 * NEWS: Likewise.
9639 2001-11-13 Akim Demaille <akim@epita.fr>
9641 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9642 hand.
9643 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9645 2001-11-13 Akim Demaille <akim@epita.fr>
9647 * lib/autotest/general.m4 (AT_INIT): After having run the test
9648 group, go back to the initial directory, not to at_suite_dir.
9650 2001-11-13 Akim Demaille <akim@epita.fr>
9652 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9653 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9654 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9655 option.
9656 (AT_CHECK_CONFIGURE): Use absolute paths.
9657 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9658 The problem is still the old one: there is no means in M4 (that I
9659 know about) to create a defining macro, because there is no means
9660 to create `$1' etc., therefore, the defining macro ``swallows''
9661 all the arguments meant to the defined macro.
9663 2001-11-13 Akim Demaille <akim@epita.fr>
9665 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9666 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9667 configure.ac.
9668 * tests/aclocal.m4: Remove, as it is no longer used.
9670 2001-11-13 Akim Demaille <akim@epita.fr>
9672 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9673 variable names when referring to a single test group, or to
9674 `suite' when referring to the whole test suite.
9675 `at_last_test' is removed: m4 compute at_format itself.
9676 (at_stdout, at_stder1, at_stderr): New variables.
9677 (AT_CHECK): Use them.
9679 2001-11-13 Akim Demaille <akim@epita.fr>
9681 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9682 in PATH.
9683 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9684 Do it as soon as a test fails, don't wait till the end of the test
9685 suite.
9686 Don't remove $as_me.[0-9]*, since these files no longer exist.
9688 2001-11-13 Akim Demaille <akim@epita.fr>
9690 * tests/tools.at: Use absolute paths, since we are no longer run
9691 in place.
9693 2001-11-13 Akim Demaille <akim@epita.fr>
9695 Now that tests are running in their own private dir, there is no
9696 need to list the files to remove at the end of tests groups.
9698 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
9699 (AT_data_files, at_data_files): Remove.
9700 (AT_CLEANUP, AT_DATA): Simplify.
9701 (AT_INIT): Adjust.
9702 Remove the group dir if !debug && !failed.
9703 * tests/atspecific.m4: Adjust.
9705 2001-11-13 Akim Demaille <akim@epita.fr>
9707 Start a new layout for Autotest: `testsuite' creates
9708 `testsuite.dir' in which the at-check-line etc. files are to be
9709 found, and `testsuite.dir/003' where the test group 3 is run.
9711 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
9712 at_check_line_file, at_format, at_test_normalized, at_group_dir
9713 are new variables.
9714 Create the directories.
9715 Use absolute paths for at- files.
9716 (AT_CHECK): Adjust.
9718 2001-11-11 Michael Matz <matz@kde.org>
9720 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
9721 (m4_car2): New.
9722 (m4_car): Properly quote arguments.
9724 2001-11-13 Akim Demaille <akim@epita.fr>
9726 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9727 with stricter rules on LIBOBJS.
9729 2001-11-12 Paul Eggert <eggert@twinsun.com>
9731 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9732 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9733 __PROTOTYPES too.
9735 2001-11-12 Akim Demaille <akim@epita.fr>
9737 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9739 2001-11-12 Akim Demaille <akim@epita.fr>
9741 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9742 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
9743 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9744 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9745 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9746 specify to what the macro should be defined (typically to 1).
9748 2001-11-12 Akim Demaille <akim@epita.fr>
9750 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9751 From Jim Meyering.
9753 2001-11-12 Akim Demaille <akim@epita.fr>
9755 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9756 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
9757 definition used by Automake where LEX is +/- "${missing} lex" and
9758 `missing' itself contains variables.
9760 2001-11-12 Akim Demaille <akim@epita.fr>
9762 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
9763 Now that M4sh pushes BODY, the comments were output at the end of
9764 the test suites.
9766 2001-11-08 Akim Demaille <akim@epita.fr>
9768 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
9769 that we can trace macros from aclocal.m4.
9770 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
9771 obsoleted, and redirect to the former anyway.
9772 Reported by Ralf Corsepius.
9774 2001-11-08 Akim Demaille <akim@epita.fr>
9776 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be

9779 instead of successive calls to autoconf.

9838 * lib/Autom4te/General.pm (@export_vars, @export_subs)
9839 (@export_forward_subs): New.
9840 Add basename, dirname, and fileparse.
9841 (@EXPORT): Adjust.
9842 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
9843 Don't look for aclocal flags if we already know aclocal is not
9844 used.
9845 Move aclocal.m4t only if it exists.
9846 Reported by Ezra Peisach.
9848 2001-11-03 Akim Demaille <akim@epita.fr>
9850 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
9851 passed on command line, defaulting to ./configure.ac if present.
9852 (&maybe_autoreconf, File::Find): Remove, unused.
9853 (&autoreconf): If autoconf is not used, don't try to trace.
9855 2001-11-02 Akim Demaille <akim@epita.fr>
9857 * configure.ac: Bump to 2.52g.
9859 2001-11-02 Akim Demaille <akim@epita.fr>
9861 Version 2.52f.
9863 2001-11-02 Akim Demaille <akim@epita.fr>
9865 * config/config.guess, config/config.sub, doc/standards.texi:
9866 * config/lispdir.m4: Update from masters.
9867 * configure.ac: Bump to 2.52f.
9869 2001-11-02 Akim Demaille <akim@epita.fr>
9871 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
9872 Don't run aclocal when aclocal.m4 is not from aclocal.
9873 From Ezra Peisach.
9874 Don't run libtoolize and gettextize if --install is not given.
9876 2001-11-01 Paul Eggert <eggert@twinsun.com>
9878 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
9879 be invoked before _AS_LINENO_PREPARE.
9880 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9881 than character ranges.
9883 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9884 invoking AS_BASENAME. Set the locale variables to 'C' if
9885 possible, as POSIX requires this to get the traditional
9886 behavior.
9887 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9889 2001-10-31 Paul Eggert <eggert@twinsun.com>
9891 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9892 with {}, as that triggers a bug in Bash 2.05.
9894 (_AS_LINENO_PREPARE): Use Sed rather than
9895 Awk. Fix the sed prepass to work even if there are multiple
9896 instances of $LINENO on the same line. Do not substitute for
9897 other variables like $LINENOT. Do not check file dates; such a
9898 check is unreliable on sufficiently fast machines, and removing
9899 the check makes the code simpler and more reliable. Check for
9900 output and chmod failures.
9902 * doc/autoconf.texi (Special Shell Variables): Document
9903 the above.
9905 2001-10-31 Akim Demaille <akim@epita.fr>
9907 * tests/Makefile.am (atconfig): Remove this target, Automake
9908 handles it now.
9910 2001-10-31 Akim Demaille <akim@epita.fr>
9912 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
9913 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
9914 provided, while it is optional.
9915 * configure.ac: Adjust.
9917 2001-10-26 Paul Eggert <eggert@twinsun.com>
9919 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
9920 lib/Autom4te/Struct.pm:
9921 Require Perl 5.005_03 instead of just 5.005, as some tests fail
9922 with 5.005_02.
9924 * doc/autoconf.texi (Special Shell Variables): Document some
9925 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
9927 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
9928 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
9929 eval $LINENO is not portable in practice.
9931 2001-10-24 Akim Demaille <akim@epita.fr>
9933 * lib/Autom4te/General.pm (backname): New.
9935 2001-10-24 Akim Demaille <akim@epita.fr>

9940 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
9942 * doc/autoconf.texi (Shellology): Mention the problems with bash
9943 2.05's use of ANSI quoting in its `set' builtin.
9945 2001-10-22 Paul Eggert <eggert@twinsun.com>
9947 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
9948 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
9949 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
9950 POSIX decided to standardize on the int flavor of strerror_r.
9951 Always do char* test, as there's no reason not to.
9952 Assign to a char* var, to catch strerror_r that returns int*.
9954 * doc/autoconf.texi (Particular Functions):
9955 Document the above changes. Also, document the fact that
9956 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
9958 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
9960 2001-10-20 Akim Demaille <akim@epita.fr>
9962 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

9967 * lib/Autom4te/General.pm (&update_file): If destination is
9968 unchanged, remove the source.
9969 (&up_to_date_p): Don't be verbose, be debug.

9971 (&autoreconf): Display the full path of the configure.ac we are
9972 studying.
9973 Trace it only once.
9974 Be sure to honor --force with gettextize.
9975 Always run aclocal.
9976 * doc/autoconf.texi: Adjust.
9978 2001-10-20 Akim Demaille <akim@epita.fr>
9980 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9981 Remove, dead.
9982 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9983 `intl' is already present, as it refuses unless --force.
9984 (&parse_args): Use -I, --include instead of the old Autoconf
9985 options.
9986 ($localdir, $autoconf_dir): Remove.
9987 (@include): New.
9988 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9990 2001-10-19 Jens Petersen <petersen@redhat.com>

10002 2001-10-19 Akim Demaille <akim@epita.fr>
10004 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
10005 comment, explain how to install automatic mode selection.
10006 From Russ Allbery.
10008 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10010 * bin/autoreconf.in (autoreconf): Display the path to the
10011 configure.ac being studied.
10013 2001-10-18 Paul Eggert <eggert@twinsun.com>
10015 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10016 long, to work around a bug in the HP C compiler version HP92453-01
10017 B.11.11.23709.GP.
10019 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10020 (AS_BASENAME_EXPR): New macro.
10021 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10022 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10023 and fall back on 'sed' only if the other two fail. This makes
10024 AS_BASENAME act more like AS_DIRNAME.
10025 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10026 contains white space.
10027 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10028 Use AS_DIRNAME, since I think it's now DOS-friendly.
10029 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10030 Allow "dirname //FOO" to return either / or //, as POSIX allows
10031 either behavior.
10033 2001-10-10 Akim Demaille <akim@epita.fr>
10035 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

10041 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

10166 * doc/autoconf.texi (config.status Invocation):
10167 CONFIG_SHELL defaults to a shell that supports LINENO if available.
10169 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
10170 shell does not support LINENO, and if CONFIG_SHELL is unset or
10171 empty, and if we can find a shell that does support LINENO,

10173 ourselves with CONFIG_SHELL.
10175 2001-10-05 Paul Eggert <eggert@twinsun.com>
10177 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

10248 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
10249 Don't use nested parenthesization. This patch was originally
10250 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
10251 but somehow it didn't get incorporated then.
10252 * doc/autoconf.texi (Limitations of Usual Tools):
10253 Clarify remark about sed and nested parenthesization.

10257 the type exists.
10258 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10259 Check for `expr' arithmetic overflow, and for compilation failure,
10260 and invoke a new argument $4 if either is discovered.
10261 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
10262 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
10264 2001-09-28 Akim Demaille <akim@epita.fr>

10278 2001-09-27 Akim Demaille <akim@epita.fr>
10280 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
10281 generates too many bug reports.
10283 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
10284 status when executing the ACTION-IF-FALSE.

10293 (Broken/missing compilers, AC_PROG_CPP with warnings)
10294 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
10295 (AC_PROG_CPP requires AC_PROG_CC): here and...
10296 * tests/fortran.at (GNU Fortran 77): there.
10297 * doc/autoconf.texi (autoconf Invocation): Fix the example:
10298 AC_TRY_RUN is about compilation, not shell commands.
10299 (Test Programs): AC_TRY_RUN works as used to be advertised.
10301 2001-09-27 Akim Demaille <akim@epita.fr>
10303 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
10304 Raja R Harinath:
10305 Be sure to detect when $LINENO always returns the same value.
10306 Look for the original script, basename($0) is certainly not
10307 enough.
10308 Pass the CLI arguments to `$as_me.lineno'.
10310 2001-09-25 Akim Demaille <akim@epita.fr>
10312 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

10324 * doc/autoconf.texi (Top): Wrap in @ifnottex.
10326 2001-09-23 Akim Demaille <akim@epita.fr>
10328 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
10329 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
10330 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
10331 builddir, buildpath, top_builddir, and top_buildpath.
10332 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
10333 the current directory.
10334 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
10335 variables *before* changing the current directory.

10338 variables.
10340 * lib/autotest/general.m4: Do not reset AT_victims.
10341 Don't compute at_srcdir nor at_top_srcdir.
10343 * tests/tools.at: Hence use top_srcdir.
10345 * tests/Makefile.am, tests/autoconf, tests/autoheader,
10346 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
10347 Remove.

10350 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
10351 * configure.ac: Build the position independent wrappers.
10353 * man/Makefile.am: Now that test wrappers are position
10354 independent, use them and drop dark envvar magic.
10356 2001-09-23 Akim Demaille <akim@epita.fr>
10358 * doc/autoconf.texi (Common Shell Constructs): Rename as...
10359 (Programming in M4sh): this.

10402 * lib/autoconf/autotest.m4: Create `package.m4'.
10403 * tests/Makefile.am (package.m4): Remove.
10405 2001-09-22 Akim Demaille <akim@epita.fr>
10407 Rely on `$LINENO' when possible instead of `__oline__'.
10409 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
10410 `$LINENO' support replacement when not supported.
10411 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
10412 them explicitly to be sure they are not output before this section
10413 (via m4_require). Cosmetic only.
10414 * lib/autoconf/c.m4, lib/autoconf/general.m4,
10415 * lib/autoconf/programs.m4: Replace all the occurrences of
10416 `__oline__' with `$LINENO'.

10419 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
10421 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
10422 character (u: -> ue) in a code comment.
10423 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
10424 it works.
10426 2001-09-21 Akim Demaille <akim@epita.fr>
10428 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
10429 Suggested by Jim Meyering.
10431 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10433 * lib/autoconf/programs.m4: Use extensions listed in
10434 $ac_executable_extensions when looking for programs.
10436 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10438 * lib/autoconf/general.m4: Fix a small Englisho.

10441 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
10443 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

10446 PATH_SEPARATOR.
10447 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
10448 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
10449 be used instead of ':'.
10450 * lib/autotest/general.m4: Replace occurrences of ':' in
10451 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
10453 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10455 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
10456 arguments. Fixed a typo.
10458 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10460 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
10461 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
10463 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10465 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
10466 * bin/autoupdate.in: Ditto.
10467 * bin/autoheader.in: Reworded a few comments.
10468 * bin/autoconf.in: Reworded help text for a few options.
10469 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10470 * bin/autoscan.in, bin/autoupdate.in: Ditto.
10472 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10474 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10475 already have $file). Set output files to binary mode (helps avoid
10476 CR issues on DOSish systems).
10478 2001-09-19 Akim Demaille <akim@epita.fr>
10480 * lib/autotest/general.m4: Englishoes.
10481 From Tim Van Holder and Alexey Mahotkin.
10483 2001-09-18 Paul Eggert <eggert@twinsun.com>
10485 * doc/autoconf.texi (Common Shell Constructs): New node,
10486 documenting AS_DIRNAME.
10487 (Limitations of Usual Tools): Refer to it when discussing dirname.
10488 Also, update discussion of POSIX standard to reflect latest draft.
10490 * lib/autoconf/c.m4:
10491 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
10493 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10494 Do not pass a first argument with leading '-'
10495 to expr, by parenthesizing initial integers that might be negative.
10497 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10498 now merely checks whether it is an error to pass an argument
10499 to getpgrp.
10501 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10502 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
10503 whether it is a (compile-time) error to pass an argument to
10504 getpgrp. This simpler test supports the revised documentation,
10505 and is all that AC_FUNC_GETPGRP's users really need.
10507 2001-09-18 Akim Demaille <akim@epita.fr>
10509 * doc/autoconf.texi (Limitations of Make) <$<>: New.
10511 2001-09-18 Akim Demaille <akim@epita.fr>

10519 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
10520 correctly.
10521 Add test for AS_BASENAME.
10522 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10523 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10524 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10525 * tests/base.at: Fixed the expected responses. The old ones were
10526 one line out...
10527 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10528 the documentation claims it should (and how it behaved in 2.13).
10530 2001-09-18 Akim Demaille <akim@epita.fr>
10532 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
10533 the AC_CONFIG_COMMANDS invocation.
10534 This also solves the name clash problems.
10535 Don't set the package's ID.
10536 * lib/m4sugar/Makefile.am (version.m4): Revamp.
10537 No longer to be shipped.
10538 (version.in): Remove.
10539 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
10540 * lib/autoconf/status.m4: Adjust.
10541 Use `m4_PACKAGE_STRING'.
10542 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
10543 the only optional argument is the name of the test suite.
10544 Expect `package.m4' to define the package signature.
10545 * lib/autom4te.in (Autotest): Add `package.m4?'.
10546 * tests/Makefile.am (package.m4): New.
10547 * tests/suite.at: ifnames is a victim.
10549 2001-09-18 Akim Demaille <akim@epita.fr>
10551 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
10552 AC_LIBSOURCE, AC_CONFIG_FILES.
10553 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
10554 program version string doesn't match the package's.
10555 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
10556 after `(cached)'.
10558 2001-09-17 Paul Eggert <eggert@twinsun.com>
10560 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10561 Allow expression to return any value that can fit into unsigned long
10562 (not int, as before). Check for output errors.
10564 2001-09-17 Bruno Haible <haible@ilog.fr>
10566 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10567 Always include <stdio.h> and <stdlib.h>. Evaluate
10568 the expression in an extra function before these includes. Call
10569 fprintf "%d" only after ensuring the argument is of type 'int'.
10570 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
10572 2001-09-17 Paul Eggert <eggert@twinsun.com>
10574 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10575 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10576 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10577 when they don't exist.
10579 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
10580 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
10581 need it.
10583 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
10584 version with the version used by fileutils 4.1, except use
10585 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
10586 we don't need it.
10588 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
10590 2001-09-13 Akim Demaille <akim@epita.fr>
10592 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
10593 _first_.
10594 Reported by Gerrit P. Haase.
10596 2001-09-13 Akim Demaille <akim@epita.fr>
10598 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
10599 m4_defn'ing is valid.

10605 Use it.

10611 (m4_re_escape): New.
10612 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER): Use it.
10613 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
10614 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
10615 Likewise.
10616 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
10617 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
10618 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
10619 AT_tests_all for consistency.
10620 Set at_victims.
10621 (AT_VICTIMS): Similar to AT_KEYWORDS.
10622 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
10624 2001-09-13 Akim Demaille <akim@epita.fr>
10626 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
10628 2001-09-13 Akim Demaille <akim@epita.fr>
10630 * lib/autotest/general.m4 (AT_INIT): Create and remove
10631 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
10632 test suites can cohabit.
10634 2001-09-13 Akim Demaille <akim@epita.fr>
10636 * tests/mktests.sh: Don't output banners for empty test files.
10638 2001-09-13 Akim Demaille <akim@epita.fr>
10640 Test suites can be run independently of configure.
10642 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
10643 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.

10652 * bin/ifnames.in: Rewrite in Perl.
10653 * configure.ac: Don't look for AWK.
10654 * tests/tools.at (AWK portability): Remove.
10655 (Syntax of the shell scripts): Don't check ifnames.
10656 (AT_CHECK_PERL_SYNTAX): New.
10657 (Syntax of the Perl scripts): Check ifnames.
10658 * tests/ifnames: New.
10660 2001-09-13 Akim Demaille <akim@epita.fr>

10663 test group titles.
10664 * tests/atspecific.m4 (AT_CHECK_AU_MACRO): AT_KEYWORDS(autoupdate).

10676 (_AT_CLEANUP_FILE_IF, _AT_CLEANUP_FILE): these.
10677 (_AT_CLEANUP_FILE_IF): Simplify the regexp.
10678 (AT_SETUP): Reset AT_line, AT_keywords, AT_description.
10679 No longer fill the HELP diversion.
10680 (AT_CLEANUP): Use them.
10681 * lib/m4sugar/m4sugar.m4 (m4_append): Support a separator.
10682 (m4_list_append): Remove.
10684 Spread a few keywords in the Autoconf test suite.
10686 2001-09-10 Akim Demaille <akim@epita.fr>
10688 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
10689 PATH_SEPARATOR, let M4sh compute it.
10690 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): New.
10691 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.
10692 Move to...
10693 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Here.
10694 Simplify when the path is not a literal.
10695 (AS_UNAME): Use it to report PATH.
10696 * lib/autoconf/general.m4 (_AC_INIT_PREPARE_FS_SEPARATORS): Remove.
10697 (_AC_INIT_DEFAULTS): AC_SUBST PATH_SEPARATOR.
10698 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Use _AS_PATH_WALK.
10699 * lib/autotest/general.m4 (AT_INIT): Use _AS_PATH_WALK to
10700 normalize the path, and to look for victims.
10701 * tests/semantics.at (AC_PATH_PROG & AC_PATH_PROGS)
10702 (AC_CHECK_PROG & AC_CHECK_PROGS): Use PATH_SEPARATOR.
10704 2001-09-07 Akim Demaille <akim@epita.fr>
10706 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
10707 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
10708 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
10709 related variables into `at_package_*'.
10710 * lib/autotest/general.m4 (AT_VICTIMS): New.
10711 (AT_INIT): Adjust for stand-alone/embedded test suites.
10712 (AS_MESSAGE_LOG_FD): Define and use it.

10717 2001-09-07 Akim Demaille <akim@epita.fr>
10719 Move toward possibly stand-alone test suites.
10721 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
10722 in addition, it introduces useless differences in logs.
10723 (AT_INIT): Let atconfig and atlocal be both optional.
10724 Adjust PATH computation.
10725 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.
10727 2001-09-07 Akim Demaille <akim@epita.fr>
10729 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon

10732 2001-09-05 Akim Demaille <akim@epita.fr>
10734 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'

10736 From Uwe Seimet.
10738 2001-09-05 Akim Demaille <akim@epita.fr>
10740 * bin/autom4te.in: --language is -l, not -s.
10742 2001-09-05 Akim Demaille <akim@epita.fr>
10744 Be ready to handle filenames as stupid as `dnl.at', for if even
10745 the maintainer is dumb enough to do that...
10747 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
10748 excellence in M4 quotation: consider `__file__' is active.
10750 And BTW, when invoking m4, pass the --include in the right order:
10751 the wrong one.
10753 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
10754 4m.
10756 2001-09-05 Akim Demaille <akim@epita.fr>
10758 * lib/Autom4te/XFile.pm: New lib file.
10759 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
10760 * bin/autoheader.in: Use it.
10762 2001-09-05 Akim Demaille <akim@epita.fr>
10764 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff
10765 defined.
10767 2001-09-05 Akim Demaille <akim@epita.fr>
10769 * lib/Autom4te/General.pm (&getopt): Work around the `-' Getopt bug.

10774 * doc/autoconf.texi (autoscan Invocation): Adjust.
10776 2001-09-05 Akim Demaille <akim@epita.fr>
10778 CVS GNU M4 doesn't like `undefine(undefined)'.
10780 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
10781 New, extracted from main.
10782 Use IO::File wherever possible.
10783 (input.m4): Be constant, use -I instead of hard coding $tmp.
10784 Therefore be a quoted heredoc.
10785 Don't invoke `_au_disable', since ac was not loaded, but just
10786 `unm4.m4'.
10788 2001-08-31 Akim Demaille <akim@epita.fr>
10790 Version 2.52d.
10792 2001-08-31 Akim Demaille <akim@epita.fr>
10794 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
10795 previous patch.
10796 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
10798 2001-08-31 Akim Demaille <akim@epita.fr>
10800 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
10801 serious problems handling heredocs in heredocs.
10802 Reported by Nicolas Joly.
10804 2001-08-31 Akim Demaille <akim@epita.fr>
10806 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
10807 (Making testsuite Scripts): Update.
10809 2001-08-31 Akim Demaille <akim@epita.fr>
10811 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
10813 2001-08-31 Akim Demaille <akim@epita.fr>
10815 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
10816 (testsuite Scripts): There is no such thing as `atconfig.in'.
10817 And actually one diagram is missing: test suite runtime.
10819 2001-08-31 Akim Demaille <akim@epita.fr>
10821 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
10822 inverse order.
10824 2001-08-31 Akim Demaille <akim@epita.fr>
10826 * bin/autoupdate.in (@include): `installcheck' revealed the path
10827 to m4sugar was lacking!
10829 2001-08-31 Akim Demaille <akim@epita.fr>
10831 * man/Makefile.am (.x.1): We really have to pass
10832 autom4te_perllibdir.
10834 2001-08-31 Akim Demaille <akim@epita.fr>
10836 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
10837 debug scripts, in particular passing explicitly listed tests to
10838 run is stupid.
10840 2001-08-31 Akim Demaille <akim@epita.fr>
10842 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
10843 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
10844 Use directly autom4te, not autoconf.
10845 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
10847 2001-08-31 Akim Demaille <akim@epita.fr>
10849 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
10850 * bin/autoheader.in (%symbol): Strip arguments of macros.

10856 2001-08-31 Akim Demaille <akim@epita.fr>
10858 * bin/autom4te.in (&parse_args): Die on unknown languages.
10859 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
10860 need for autoconf.
10861 Promote --include over --macrodir and other obsolete options.
10863 2001-08-31 Akim Demaille <akim@epita.fr>
10865 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
10866 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
10867 * bin/autom4te.in ($autoconf): Pass --force.
10868 `print $out' doesn't print `$_' but `$out'.
10869 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
10870 (autoheader): Pass --force since the test suite goes too fast for
10871 the time stamps.
10872 Adjust to the new autoheader messages.
10874 2001-08-31 Akim Demaille <akim@epita.fr>
10876 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
10877 Check the completeness of the #template.
10878 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
10879 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
10880 invocation.

10884 * lib/Autom4te/General.pm (&find_file, &update_file): New.
10885 * bin/autoupdate.in, bin/autoheader.in: Adjust.
10886 Drop AC_MACRODIR dead for real.
10887 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
10888 `autoheader: `config.hin' is created'.
10889 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
10891 2001-08-31 Akim Demaille <akim@epita.fr>
10893 * bin/autoheader.in: Rewrite in Perl.
10894 * tests/autoheader: Adjust.
10896 2001-08-31 Akim Demaille <akim@epita.fr>
10898 * bin/autoconf.in (--include, -I): New option.
10899 Map --localdir, --autoconf-dir onto it.
10900 Forward autom4te's options instead of interpreting them.
10901 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
10902 There is no such envvar since the inception of autom4te.cfg.
10903 * bin/autom4te.in (&parse_args): Uniquify `@include'.
10904 * bin/autoupdate.in: Adjust, and perform more control.
10905 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
10906 * tests/autoconf: Dittowise.
10908 2001-08-31 Akim Demaille <akim@epita.fr>
10910 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
10911 * bin/autom4te.in (&find_file): Support `FILE?' standing for
10912 optionally `FILE'.
10913 Use -e, not -f, since /dev/null for instance is OK.
10914 (&parse_args): Adjust.
10915 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
10917 2001-08-31 Akim Demaille <akim@epita.fr>
10919 * configure.ac: Also find tested executables in bin.
10920 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
10921 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
10922 installed peer executables, only PATH is allowed to resolve it.
10923 Pass `autoconf_dir' via options, not via invisible envvars.
10924 * lib/Autom4te/General.pm (&find_peer): Remove.
10925 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
10926 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
10927 * man/Makefile.am: Let help2man rely on PATH instead of trying to
10928 find the executables for it.
10929 * tests/Makefile.am: Major cleanup. Too lazy to document...
10930 * tests/atlocal.in: Remove all the obscure envvar manipulations.
10931 We only need PERL.
10932 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
10933 indeed related to running the test suite, while passing
10934 --autoconf-dir and others is related to running non installed
10935 Autoconf executables. So don't do that, leave it to...
10936 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
10937 * tests/autoscan: New.
10938 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
10939 refer to library files: rely on --language.
10941 2001-08-29 Akim Demaille <akim@epita.fr>
10943 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
10944 s/--set/--language/.
10946 2001-08-29 Akim Demaille <akim@epita.fr>
10948 * doc/autoconf.texi: Strip the @nodes.
10949 Suggested by Paul Eggert.
10950 (Initializing configure): Typo.
10952 2001-08-29 Akim Demaille <akim@epita.fr>
10954 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
10955 Suggested by Paul Eggert.
10957 2001-08-29 Akim Demaille <akim@epita.fr>
10959 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
10960 download in a tmp dir.
10962 2001-08-29 Akim Demaille <akim@epita.fr>
10964 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
10965 case insensitive OSes out there :(
10966 From Tim Van Holder.
10968 2001-08-29 Akim Demaille <akim@epita.fr>
10970 * lib/autom4te.in: New.
10971 * lib/Makefile.am (edit, autom4te.cfg): New.
10972 * bin/autom4te.in (BEGIN): Simplify.
10973 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.

10975 (&parse_args): Support --mode, --set, and --melt.
10976 * bin/autoconf.in: Simplify and adjust.
10977 * tests/Makefile.am (AUTOMAKE): Use --set.
10978 * tests/atlocal.in: Adjust.
10979 * BUGS: distcheck and check are weak.
10981 2001-08-29 Akim Demaille <akim@epita.fr>
10983 * lib/autotest/general.m4: Use
10984 foo=`(command) 2>/dev/null`
10985 not
10986 foo=`command` 2>/dev/null
10987 (at-devnull): Rename as...
10988 (AT-devnull): this.
10989 (--clean): Remove AT-* files too.
10990 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
10991 Reported by Nicolas Joly.
10993 2001-08-28 Akim Demaille <akim@epita.fr>
10995 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

11007 Support test ranges as arguments to the testsuite.
11008 Have -e imply -d as the help text suggested.
11010 2001-08-27 Akim Demaille <akim@epita.fr>
11012 * Makefile.maint: Formatting changes.

11025 * lib/autotest/general.m4 (AT_INIT): Log the command line.

11046 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11047 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11048 readable.
11049 Adjust callers.
11050 * doc/autoconf.texi (Configuration Actions): Document the vars
11051 available in commands.
11052 Emphasize the risks of collisions in init-cmds.

11084 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
11085 -> ac_dir).
11086 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
11087 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
11089 2001-08-27 Akim Demaille <akim@epita.fr>

11134 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11135 the name of the directory they're in, instead of the filename,
11136 since version.m4 is now in m4sugar, but m4_acversion must not be
11137 classified as an Autoconf macro.
11138 ($input_m4): Don't qualify the path to m4sugar.
11139 Rather, pass autoconf_dir to m4.
11140 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

11155 of config.log on traps.
11156 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
11157 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
11158 for config.status'.
11159 Open the log as soon as possible.
11160 Use the same log introduction as configure's.

11224 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
11225 * NEWS, README, README-alpha, TODO, tests/README: This package is
11226 `Autoconf', not `autoconf' (the executable).
11228 2001-08-20 Akim Demaille <akim@epita.fr>
11230 Info readers seem to need `Index' in the index node title :(
11232 * doc/autoconf.texi: Reverse the 2001-08-15 change which
11233 simplified index node names.
11235 2001-08-20 Akim Demaille <akim@epita.fr>

11277 2001-08-20 Akim Demaille <akim@epita.fr>
11279 Huh!?!?! There are still some user EOF tags used, which prevents
11280 their use in AC_CONFIG_COMMANDS for instance...
11282 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
11283 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
11284 `_CSEOF', or `_ATEOF', as appropriate.

11346 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
11347 `$0.log' as for projects where testsuite is in src, we'd have

11362 2001-08-17 Akim Demaille <akim@epita.fr>
11364 * doc/autoconf.texi: Work around Texinfo buglets.
11365 (Transformation Rules): One example is enough, users are expected
11366 to have their brains on. And BTW, use DESTDIR.
11367 (dvar): New macro. Use it.
11369 2001-08-17 Akim Demaille <akim@epita.fr>
11371 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

11419 (cvs-dist): depends upon it.
11421 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
11423 * tests/Makefile.am: Use a clean-local rule to remove
11424 autom4te.cache (it's a directory, not a file.
11425 * Makefile.am: Ditto (but maintainer-clean-local).
11427 2001-08-15 Akim Demaille <akim@epita.fr>
11429 * bin/autom4te.in (@m4_warning): New.
11430 (&handle_m4): Use it.
11431 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
11432 warnings are issued at each run.
11433 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
11434 is in the src tree.
11436 2001-08-15 Akim Demaille <akim@epita.fr>

11439 don't waste time running `autoupdate --version' works.
11440 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
11442 2001-08-13 Akim Demaille <akim@epita.fr>
11444 * doc/autoconf.texi (ma): Rename this index as...

11497 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
11499 * tests/semantics.at (AC_C_BIGENDIAN): New test.
11501 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11503 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
11504 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
11505 * doc/autoconf.texi (C Compiler Characteristics): Update
11506 documentation for AC_C_BIGENDIAN.
11508 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11510 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11511 magic values from an object file when cross-compiling.
11512 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11514 2001-08-10 Akim Demaille <akim@epita.fr>
11516 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11517 effects.
11518 Suggested by Russ Allbery.
11520 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11522 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11523 current $prefix to the sub-configures.
11525 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11527 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
11528 extension (needed on BeOS). Reported by Guido van Rossum.
11530 2001-08-09 Akim Demaille <akim@epita.fr>
11532 * bin/autom4te.in ($icache): Load it only if older than autom4te.
11534 2001-08-07 Akim Demaille <akim@epita.fr>
11536 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11537 removed.
11538 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11539 No need to remove the files before and after the each test, before
11540 each test and at the end of the suite is enough.
11541 Display only the children `times', not the shell's.
11542 If the test failed or was skipped, at-times is not available.
11544 2001-08-07 Akim Demaille <akim@epita.fr>
11546 Always produce testsuite.log, including when there are no
11547 failures. This helps getting information on skipped tests, and
11548 duration of the tests. Err, implement the latter btw.
11550 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
11551 Dump information on the first run of each test.
11552 (AT_CLEANUP): Create `at-times' containing the duration of the
11553 test group.
11555 2001-08-07 Akim Demaille <akim@epita.fr>
11557 The use of `dumpstat' revealed that `len' was used although it
11558 should not. m4_text_wrap was using it, but in the Autoconf world
11559 where it is legal. Hence (i) test M4sh in its own world, not
11560 Autoconf's, and (ii), ahem, fix the bug :)
11562 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11563 does not like `' instead of [].
11564 (AT_INIT): Forbid `^_?AT_'.
11565 And don't output such tokens.
11566 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11567 `script.as', and `autom4te.cache'.
11568 Remove `empty' and `macro' which are no longer used.
11569 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11570 * tests/m4sugar.at: Use it.
11571 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11573 2001-08-07 Akim Demaille <akim@epita.fr>
11575 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
11577 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
11579 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.

11592 Don't rely on M4sugar outputting the patterns in files, since we
11593 might process the output _without_ running m4, hence without these
11594 files.

11597 * bin/autom4te.in (@Request::includes): Remove, unused.

11637 Class::Struct as Autom4te::Struct.

12158 provide an alternate 'main' function name, using the 'main' from
12159 the Fortran libraries.

12161 cross-language link tests can be performed successfully.
12162 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
12163 after $LIBS, for consistency; this should be the general rule since

12165 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.

12203 2001-06-25 Akim Demaille <akim@epita.fr>
