1 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
3 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4 Require that long long int be at least 64 bits wide. C99 requires
5 this and enough programs depend on it so we should check for it.
6 Bruno Haible reports in
7 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
8 that long long int is 32 bits wide with some nonstandard compilers.
9 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
11 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
13 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
14 to a nonexistent file, so that we don't have to worry about
15 a local site configuration that doesn't use /usr/local.
16 Problem reported by Keith Marshall in
17 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
19 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
21 * doc/autoconf.texi: Be more consistent about using @acronym with
22 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
23 quite right (it talked about "OSF/Tru64", even though the
24 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
25 and it even mentioned "OSF 4"!) and at this point there's little
26 reason to talk about OSF any more, since it died in 1994.
27 (Specific Compiler Characteristics): Simplify example of
28 negative-size array.
29 (File Descriptors): Reorder to make the text flow better.
30 Remove joke about "appreciate the various levels"; I didn't get it.
31 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
32 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
33 (File Descriptors, Limitations of Usual Tools):
34 Tone down the advice against renaming or removing open files.
35 (Limitations of Usual Tools): Add a new section, on 'rm'.
37 2006-06-26 Stepan Kasal <kasal@ucw.cz>
39 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
40 -lXt in LIBS, idea from Karsten Hopp; this was due since
41 this change:
43 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
44 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
45 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
46 (which belong to Xt, not X itself). See Debian bug 327655.
48 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
50 * configure.ac (AC_INIT): Bump to 2.60a.
51 * NEWS: Update.
53 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
55 Version 2.60.
57 * configure.ac, NEWS: Update.
59 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
61 * config/texinfo.tex: Sync from upstream.
63 * bin/autom4te.in (handle_traces): Transform the `@S|@'
64 quadrigraph correctly in traces.
66 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
67 Fix typos.
69 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
70 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
71 not defined.
72 * doc/autoconf.texi (Changed Directory Variables): New node,
73 to document the whole `datarootdir' business a bit better.
74 * NEWS: Update.
75 * tests/torture.at (datarootdir workaround): Extend test.
76 Prompted by report by Alexandre Julliard.
78 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
80 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
81 when using default mode of IBM C 6 for AIX. Problem and two-line
82 fix reported by Larry Jones.
84 2006-06-22 Alexandre Julliard <julliard@winehq.org>
86 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
87 about literal '${datarootdir}' if a definition is found in the
88 output file.
90 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
92 * NEWS: Use "M4" rather than "m4" when appropriate.
93 Problem reported by Eric Blake.
94 * doc/autoconf.texi: Likewise.
95 Use @acronym around BSD, GCC, and GNU when appropriate.
96 (Why GNU M4): Renamed from "Why GNU m4".
97 (Redefined M4 Macros): Mention that Posix
98 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
99 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
100 to int.
102 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
104 * bin/autom4te.in (handle_output): Do not forbid the empty
105 pattern.
106 * tests/tools.at (autoconf: the empty token): New test.
108 2006-06-20 Stepan Kasal <kasal@ucw.cz>
110 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
111 calls, so that we do not care whether they are LIFO or FIFO;
112 in the m4_wrap, do not check which diversion is the topmost
113 one, just check that the stack is balanced at the end.
114 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
115 base diversion forever--pop the previous diversion before
116 opening the new one; consequently, remove the m4_wrap call.
117 * lib/autotest/general.m4 (AT_INIT): Likewise.
118 * tests/m4sugar.at: Do not use
119 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
121 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
122 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
124 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
125 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
126 Rework example of m4wrap token-pasting trouble so that it doesn't
127 care whether it's LIFO or FIFO.
128 Fix some "contrary to"s that are awkward in English.
130 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
132 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
133 to `yes' instead of `int$1_t' if the type is found, for more
134 consistent configure output (where $1 is the number of bits).
135 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
136 Suggested by Bruno Haible.
138 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
139 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
140 with system headers. Report by Bruno Haible.
142 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
144 * config/config.guess, config/config.sub: Sync from upstream.
146 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
147 in order to avoid picking up an older installed frozen m4sh.m4f.
148 Besides an outdated shell startup, this could have been created
149 by an earlier M4 version with incompatible frozen file format.
151 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
153 * README: Recommend m4 1.4.4 instead of 1.4.3..
154 * doc/autoconf.texi: Likewise.
155 (Special Chars in Names): Say that $(.FOO) is portable, as
156 suggested by Stepan Kasal.
157 (Installation Directory Variables, Build Directories):
158 (Automatic Remaking, Subdirectories, Fortran Compiler):
159 (Making testsuite Scripts, Defining Directories):
160 Quote variable usages better.
161 (Making testsuite Scripts): Add clean-local rule to makefile
162 snippet, by Eric Blake.
163 (Installation Directory Variables): Fix table item font.
164 Reword slightly to clarify. Generalize advice about
165 not using special characters to include all file-related
166 vars, not just VPATH.
167 (Special Chars in Variables): Warn about special characters in
168 $(srcdir) too.
169 (Assignments): Clarify default-value example as suggested by
170 Ralf Wildenhues in
171 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
172 (Special Shell Variables): Note leading ./ or ../, as suggested
173 by Eric Blake.
174 (Limitations of Builtins): Under cd, warn about CDPATH.
175 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
176 Ralf Wildenhues.
178 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
180 * doc/autoconf.texi (Configuration Actions): Remove duplicate
181 `@var', for texi2html.
182 (Systemology): Some more word wrapping, for DVI output.
183 (autom4te Invocation): The short option for `--melt' is `-M',
184 not `-m'.
186 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
188 * doc/autoconf.texi: More formatting and English tweaks,
189 many suggested by Ralf Wildenhues.
190 Reword to avoid "@code{...}'s" and the like, since it's ugly
191 with Emacs info mode. discontents -> woes.
192 Put a few "will"s back. time stamp -> timestamp.
193 side-effect -> side effect.
195 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
197 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
198 Warn about $@ not persisting. Problem reported by Julien Danjou in
199 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
200 (Special Chars in Names): Renamed from Leading _ in Macro Names.
201 Mention other special chars, too.
203 2006-06-14 Eric Blake <ebb9@byu.net>
205 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
207 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
209 * doc/autoconf.texi: Some systematic minor improvements, as
210 follows. Use "makefile" when talking about makefiles
211 generally (which might be named "makefile" or "Makefile" or even
212 "foo.mk"), "Makefile" when talking about a specific makefile
213 called "Makefile". This unclutters the text from weird quotes
214 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
215 values" rather than "@var{foo}s" and similar constructs containing
216 "}s". Use "Make rules" rather than "Makefile rules". Minor
217 English-language improvements. Change the prefix "sub-" to "sub"
218 and "re-" to "re".
219 Put blank lines around examples more consistently.
220 Avoid "rather" and "very" as intensifiers.
221 Avoid "will" as an auxiliary.
222 (Limitations of Make): Split this node into....
223 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
224 (Leading _ in Macro Names, Backslash-Newline-Newline):
225 (Backslash-Newline Comments, Long Lines in Makefiles):
226 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
227 (obj/ and Make, make -k Status, VPATH and Make):
228 (VPATH and Double-colon, $< in Explicit Rules):
229 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
230 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
231 New nodes, resulting from splitup of Limitations of Make.
232 All cross-references changed. Raise the top node from
233 a section to a chapter, and all subnodes accordingly.
234 Redo the introductory wording to match the new organization.
235 (Installation Directory Variables): Use an example that is
236 closer to what Autoconf actually does. Mention that VPATH's
237 value should not contain metacharacters or white space.
238 (Fortran Compiler): Fix a VPATH bug in an example.
239 (Leading _ in Macro Names): Mention that this problem is no longer
240 of practical concern.
241 (VPATH and Make): Reword the advice to make it clearer
242 that Autoconf and Automake support VPATH in non-GNU make, but
243 many packages have bugs in this area.
244 ($< in Explicit Rules): Refer to Build Directories rather
245 than using a (non-VPATH-safe) example.
246 (Automatic Rule Rewriting): Mention the sort of disaster that
247 can ensue with Solaris-style rule rewriting with VPATH.
249 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
251 * doc/install.texi (Compilers and Options): Weaken the
252 suggestion to use GNU make for VPATH builds.
254 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
255 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
257 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
258 in regular expression.
260 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
262 * doc/autoconf.texi (Installation Directory Variables):
263 Drop extra @samp from `@table @samp' item.
264 (Limitations of Usual Tools): Comment fix.
265 Do not nest @samp just to point to other table items.
266 (Writing testsuite.at) <AT_CHECK>: The second argument to
267 `@dvar' is already @samp'ed.
268 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
269 do not use @var in the second argument.
271 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
273 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
274 $as_shell.exe too. Problem reported by Andreas Buening in
275 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
277 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
279 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
280 `unused variable' compiler warning, for `-Wall -Werror'.
281 Reported by Jaap Haitsma in
282 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
284 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
286 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
287 case the compiler dumps core. Problem reported for
288 OpenServer 5.0.7 by Tim Rice in
289 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
290 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
291 Likewise.
293 2006-06-06 Tim Rice <tim@multitalents.net>.
295 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
296 "ERROR" only shows up in "make check" output if there is an
297 error.
299 2006-06-06 Eric Blake <ebb9@byu.net>
301 * tests/tools.at (automatically allowed tokens): Fix typo.
303 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
305 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
307 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
308 typically overflows on x86 CPUs, even though the C standard
309 requires otherwise.
311 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
313 * configure.ac (AC_INIT): Bump to 2.59e.
314 * NEWS: Update.
316 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
318 Version 2.59d.
320 * config/texinfo.tex: Sync from upstream.
322 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
323 seen, invoke libtoolize with `--ltdl' argument.
324 * lib/autom4te.in (Autoreconf-preselections): Adjust.
325 * NEWS: Update.
326 Suggested by Eric Blake.
328 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
330 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
331 reported by Ralf Wildenhues.
332 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
334 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
336 * THANKS: Update.
338 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

345 message issued by AC_REQUIRE.
346 * tests/m4sugar.at: Check m4_require's error message.
347 * tests/base.at: Check AC_REQUIRE's error message.
348 * tests/local.at (AT_CHECK_M4): New macro, almost identical
349 to...
350 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
351 AT_CHECK_M4.
352 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
353 `expout' as the last parameter.
354 * tests/tools.at: Adapt to the above change.
356 2006-06-04 Stepan Kasal <kasal@ucw.cz>
358 * doc/autoconf.texi (Limitations of Usual Tools): Correct
359 information about race-free implementations of mkdir.
361 2006-06-04 Eric Blake <ebb9@byu.net>
363 * bin/autoreconf.in (help): Document M4 environment variable.
364 * bin/autoconf.as (Usage): Likewise.
365 * bin/autom4te.in (help): Likewise.
366 * doc/autoconf.texi (autom4te Invocation): Likewise.
368 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
370 * NEWS: GNU make now recommended for VPATH builds.
371 Mention that some macros are now documented to be obsolescent.
372 * doc/autoconf.texi:
373 Prefer "current" to "modern" to describe
374 currently-used (albeit perhaps old-fashioned) hosts.
375 Mention which ancient features no longer need to be worried about.
376 setgid -> set-group-ID
377 setuid -> set-user-ID (these are the Posix terms)
378 Fix some misuses of "only".
379 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
380 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
381 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
382 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
383 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
384 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
385 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
386 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
387 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
388 Mention that these macros are obsolescent.
389 (Installation Directory Variables): shall -> should
390 (File Descriptors): Mention that 0, 1, 2 might get reopened.
391 Mention that it's now safe to use 3 and 4.
392 (Limitations of Usual Tools): cp -r is now specified by Posix.
393 Omit longwinded and obsolescent discussion of cp -f.
394 Modernize discussion of expr, ls.
395 (Limitations of Make): Modernize discussion of VPATH builds.
396 Mention $? as a workaround in some cases.
397 * doc/install.texi (Basic Installation):
398 Mention "./configure; make; make install" first. Be more
399 specific about why this file is generic. Remove unnecessary
400 parens. Remove misleading "only". Remove obsolete advice
401 about csh. Don't say "configure" takes awhile; say it
402 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
403 and CC=c99 rather than CC=c89, as these are blessed by current
404 Posix. Recommend GNU make if doing a VPATH build.
406 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
408 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
409 examples involving shell prompts.
411 2006-06-02 Stepan Kasal <kasal@ucw.cz>
412 and Paul Eggert <eggert@cs.ucla.edu>
414 * doc/autoconf.texi (Here-Documents): Add details about the
415 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
416 use "here-documents" instead of "here documents".
418 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
420 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
422 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
424 * doc/autoconf.texi (File System Conventions): Warn about ":"
425 anywhere in directory names.
427 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
429 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
430 about quoting the case statement, just in case.
431 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
432 was fixed in ksh93g; reported by Ralf Wildenhues.
434 2006-05-31 Stepan Kasal <kasal@ucw.cz>
436 * doc/autoconf.texi (System Services): Do not document
437 overriding EXEEXT via ac_cv_exeext=ext.
438 (Particular Programs) <AC_PROG_MKDIR_P>:
439 Document that ${MKDIR_P} understands --.
440 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
441 comment.
443 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
445 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
446 argument with leading hyphen. Problem reported by Paul Eggert.
448 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
450 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
451 about quoting ac_try: quote all of it, if any of it seems suspicious.
452 This means we don't have to worry about ${ or sed any more.
453 Also, double-quote the case statement, to work around misuses via
454 underquoting as reported by Ralf Wildenhues in
455 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
456 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
457 undocumented and dangerous macro.
458 Problem reported by Ralf Wildenhues in
459 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
461 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
463 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
464 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
465 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
467 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
469 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
470 since evidently some packages rely on the old, broken behavior.
471 Problem reported by Ralf Wildenhues in
472 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
473 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
474 pre-2006-05-26 definitions, but leave in the comments that
475 these macros are dangerous and should not be used.
476 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
477 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
478 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
479 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
480 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
482 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
484 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
485 the use of 'tr', since this is our only use of 'tr'.
487 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
488 and Paul Eggert <eggert@cs.ucla.edu>
490 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
491 Don't assume 'grep' works on long lines, since AIX grep doesn't.
493 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
495 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
496 the output file in the `${datarootdir}' test.
498 2005-05-28 Stepan Kasal <kasal@ucw.cz>
499 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
501 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
502 mention of `datarootdir' in the input file(s), but literal
503 `${datarootdir}' in the output file, and we haven't warned yet,
504 then warn as well: the user may have (erroneously) used
505 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
506 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
507 * tests/torture.at (datarootdir workaround): Extend this test.
508 * NEWS: Update.
510 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
511 and Paul Eggert <eggert@cs.ucla.edu>
513 * doc/autoconf.texi (autoheader Invocation): The first argument to
514 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
515 alternatives and clear up the language a bit.
517 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
519 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
520 ac_config_guess, ac_config_sub, ac_configure.
521 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
522 Fix typo that prevented an unnecessary space from being removed.
523 Problems reported by Ralf Wildenhues in:
524 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
526 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
528 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
529 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
530 Don't use the term "thread-safe" to talk about mkdir race
531 conditions, since the problem is more a process than a thread
532 issue. Problem reported by Stepan Kasal in:
533 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
534 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
535 the test for 'install' more closely. Look at MKDIR_P first.
536 Look in the PATH, and at /opt/sfw/bin.
537 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
538 Don't bother to try mkdir -p, since we already check mkdir --version;
539 just look at the version number. (There's no easy way to check
540 for race-free implementations.)
541 * tests/tools.at (autoconf: subdirectories): Adjust to above
542 changes, since MKDIR_P now might end in "/mkdir -p".
544 * doc/autoconf.texi (autoheader Invocation): Mention that the
545 first arg of AC_DEFINE_UNQUOTED must be a literal.
546 Problem reported by Ben Pfaff in
547 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
549 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
550 * doc/autoconf.texi (Special Chars in Variables): New section.
551 (Preset Output Variables): Warn about special chars in CPPFLAGS.
552 (Installation Directory Variables): Quote $(datadir) better.
553 (Limitations of Builtins): Describe some of eval's trickiness.
555 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
556 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
557 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
558 in front of every arg, not just trailing args. Quote apostrophes.
559 (_AC_EVAL_ECHO): New macro.
560 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
561 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
562 removed.
563 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
564 exposed by quoting of eval argument. Put the command on line line
565 so it logs better.
566 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
567 (_AC_PATH_X, AC_PATH_X): Quote more safely.
568 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
569 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
570 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
571 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
572 Use eval more safely.
573 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
574 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
575 to be replaced.
576 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
577 lines, exposed by quoting of eval argument.
579 2006-05-26 Stepan Kasal <kasal@ucw.cz>
580 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
582 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
583 initialization of `ac_cv_exeext', do not override it if it was
584 already set, unless it was set to `no', for compatibility with
585 Autoconf-2.13, and comment this.
586 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
587 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
588 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
589 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
590 Document that this test may be overridden by setting
591 `ac_cv_exeext'.
593 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
595 Revert these two patches:
597 2006-04-06 Eric Blake <ebb9@byu.net>
598 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
599 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
600 2006-04-01.
602 2006-04-01 Stepan Kasal <kasal@ucw.cz>
603 Clean up _AC_COMPILER_EXEEXT* macros.
604 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
605 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
606 ac_file to the name of the default output file and call
607 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
608 initial `rm' of the candidate files...
609 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
610 the same list in subsequent `rm' calls, and for the temporary
611 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
612 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
613 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
614 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
615 no longer needed) by libtool. Make it a cache check.
616 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
617 copied here by mistake.
618 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
619 _AC_COMPILER_EXEEXT.
620 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
621 _AC_COMPILER_OBJEXT directly.
622 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
624 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
626 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
627 Fix description of how the buggy `sed' works.
629 2006-05-25 Noah Misch <noah@cs.caltech.edu>
631 Sync from Automake:
633 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
634 ENOLCK. Only mention `make -j' when applicable. Only raise
635 fatal errors when `make -j' is involved. Improve error message.
637 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
639 * doc/autoconf.texi (Here-Documents): We now know more about
640 the variable expansion in here documents bug.
641 Thanks to Tim Rice and Stepan Kasal.
643 * doc/autoconf.texi (Making testsuite Scripts): Add an example
644 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
646 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
648 * tests/autotest.at (Multiline command from M4 expansion):
649 No failure to be expected if the shell quotes newlines in
650 commands in the `set -x' output. Report by Tim Rice.
651 * THANKS: Update.
653 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
655 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
656 expansion in the here-documents used by config.status, as that
657 runs afoul of the Korn shell version M-12/28/93d bug described in
658 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
659 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
660 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
662 2006-05-23 Jim Meyering <jim@meyering.net>
664 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
665 Fix typo introduced with 2006-04-02 change. It reversed the sense
666 of the test.
668 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
670 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
671 ac_dB slightly, to save bytes in the script.
672 Max out at 50 lines, rather than 96; this is more likely
673 (though not guaranteed) to avoid obscure 'sed' failures.
675 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
677 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
678 `tr -d -' as bad option argument. Work around this by deleting
679 an unrelated character.
680 Report by Tim Rice <tim@multitalents.net>.
682 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
683 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
684 Stepan Kasal <kasal@ucw.cz>
686 * doc/autoconf.texi (Particular Programs): Do not promise that
687 we always prefer the GNU version of the program, and that we
688 search according to PATH; both rules can have exceptions.
689 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
690 AC_PROG_SED. Move descriptions of limitations
691 to the Limitations of Usual Tools section.
692 (Limitations of Usual Tools) <sed>: Mention script length
693 limitations with Solaris /usr/ucb/sed.
694 <grep>: Fix wording for empty alternative. Mention that -c and
695 -l should not be combined, and that -E and -F should not be
696 combined.
698 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
699 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
701 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
702 limits in Solaris 8 /usr/ucb/sed by testing a long script.
704 2006-05-22 Stepan Kasal <kasal@ucw.cz>
706 * doc/autoconf.texi (Defining Symbols): Literal parameter of
707 AC_DEFINE is now passed to m4_pattern_allow.
708 * NEWS: Mention that; likewise for AC_SUBST.
709 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
710 the parameter to m4_pattern_allow.
711 * tests/tools.at: Add a check for that.
713 2006-05-22 Stepan Kasal <kasal@ucw.cz>
715 * lib/autoconf/status.m4: Fix typos.
717 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
719 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
720 only the files that this macro generates.
722 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
724 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
725 the HP-UX sed limitation of 99 commands, labels do not count.
726 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
727 in the comment.
728 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
730 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
732 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
733 Import the following fix from coreutils:
735 2006-01-13 Jim Meyering <jim@meyering.net>
737 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
738 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
739 not double-quote uses of that variable, to accommodate the rare
740 case in which getmntent is available in none of the libraries
741 checked. This happens at least on FreeBSD 5.0.
743 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
745 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
746 ac_config_guess, ac_config_sub, and ac_configure, since evidently
747 some other programs unwisely rely on these undocumented vars.
748 But put in warning comments about them.
749 Problem reported by Ralf Wildenhues in
750 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
751 * NEWS: Document that these variables are intended to go away.
753 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
755 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
756 and set the language to C++ (analogous to the equivalent Fortran
757 tests).
759 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
760 * doc/autoconf.texi (C++ Compiler): Document it.
761 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
762 * NEWS: Update.
764 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
766 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
767 that caused config.status to generate 100-command sed scripts; the
768 portable limit is 99.
770 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
772 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
773 variable `ac_d' instead of `d' to avoid infringing namespace.
774 Report by Ralf Menzel.
776 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
778 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
779 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
780 * tests/tools.at (autoconf: subdirectories): New test, taken from
781 the corresponding problem report by Ralf Wildenhues in:
782 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
784 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
785 Quote some uses of shell variables if they might suffer unexpected
786 globbing. This doesn't fix all instances of quoting problems that
787 I found, just the easy ones that look safe.
788 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
789 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
790 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
791 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
792 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
793 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
794 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
795 Likewise.
796 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
797 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
799 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
801 * bin/autoreconf.in ($help): Reword according to the manual.
802 Suggested by Olly Betts.
804 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
805 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
807 * bin/autoreconf.in: Pass the directory argument to
808 `require_configure_ac'. Fix comment.
809 * tests/torture.at (Configuring subdirectories): Expose this.
810 Reported by Olly Betts.
812 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
814 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
815 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
816 Automake as follows:
818 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
819 `$configure_in' instead of `configure.in', to preserve
820 directory component.
822 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
824 * config/config.guess, config/config.sub, config/texinfo.tex,
825 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
827 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
829 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
830 test for C99 conformance; (bool) 0.5 is an integer constant
831 expression, but (bool) -0.5 is not. Problem reported by Fedor
832 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
834 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
836 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
837 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
838 Warn about obsolete install-sh files. Remove stray sentence
839 fragment and fix cross reference.
840 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
841 install -d; this undoes the 2006-05-10 change.
842 (MKDIR_P): Mark with AN_MAKEVAR.
843 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
844 that we don't require $INSTALL to be thread-safe. Move comments
845 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
846 of AC_PROG_INSTALL. Output a message saying that we're checking
847 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
848 MKDIR_P instead of AC_SUBST.
849 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
850 Special magic for MKDIR_P, too.
851 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
852 a dnl.
853 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
855 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
857 Sync from Automake, as follows:
859 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
860 * config/install-sh: Initialize IFS, so field splitting isn't
861 turned off later.
862 * config/mkinstalldirs: Likewise.
863 * config/missing: Remove superfluous quotes. Replace all uses of
864 `[' by `test', for consistency, and for..
865 * config/missing (sed_minuso, sed_output): New variables.
866 (autom4te, help2man, makeinfo): Use them. Unifies detection of
867 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
868 Fixes `missing' to detect `--output' for help2man. Fixes
869 PR automake/483. Report by Dennis J. Linse.
870 (autom4te): Document in `missing --help'.
872 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
874 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
875 * config/install-sh: Don't use 'path' to talk about file names,
876 as per GNU coding standards. Close a race condition reported by Ralf
877 Wildenhues and Stepan Kasal. There is still a race condition
878 on hosts that predate Posix 1003.1-1992, but we can't help this.
879 Don't mishandle weird characters like space on pre-Posix hosts.
880 Invoke mkdir at most once per dir arg on pre-Posix hosts.
881 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
882 AC_PROG_MKDIR_P from AS_MKDIR_P.
883 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
884 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
885 earlier editions are not (including Automake 1.8.3).
886 Do not suggest mkinstalldirs for thread-safety.
887 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
888 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
889 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
890 presence of special characters and race conditions.
891 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
892 in Autoconf's name space.
894 2006-05-10 Bruno Haible <bruno@clisp.org>
895 and Paul Eggert <eggert@cs.ucla.edu>
897 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
898 from Automake with minor changes.
899 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
901 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
903 * config/install-sh: Update to Automake CVS version, as follows:
904 2006-04-25 Stepan Kasal <kasal@ucw.cz>
905 * lib/install-sh: Simplify the expr implementation of dirname.
906 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
907 * lib/install-sh: Handle --, and diagnose unknown options.
909 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
911 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
912 `./autom4te' to create `./testsuite', since the `all' target
913 will ensure its presence, but `installcheck' should not create
914 the uninstalled wrappers.
916 * tests/torture.at (Unusual Automake input files): Skip if we
917 detect automake < 1.8.
919 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
921 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
922 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
923 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
924 * NEWS: Update.
926 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
928 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
929 munge (multiple) white space and other oddities.
930 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
931 single quotes in variable assignment.
932 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
933 and similar failures by adding multiple spaces, tabs, and other
934 special characters.
935 Report and different test suggested by Francesco Romani
936 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
938 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
939 single quotes, we only need to search for single quotes; this
940 both simplifies the search pattern, and makes us less
941 susceptible to `echo' variations for arguments not containing
942 single quotes.
943 (_AC_ARG_VAR_VALIDATE): Likewise.
945 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
947 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
948 `$*' and IFS concatenation issue with traditional shells and
949 bash-2.04. Report by Seanster@Seanster.com.
951 2006-05-03 Bruno Haible <bruno@clisp.org>
953 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
954 precisely which Mac OS X versions have the od problem.
956 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
958 * doc/autoconf.texi: Use @option systematically.
960 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
961 and Bruno Haible <bruno@clisp.org>
963 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
964 about 'od'.
965 (Integer Overflow): Mention the special case of integer division
966 overflow.
968 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
970 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
971 traditional shells like the Solaris one that do not use the
972 first IFS character for assembling `$*'.
973 Prompted by a related report from autoconf_bug@nro.ca.
975 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
976 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
978 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
979 Mention more problems with the -e option.
981 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
983 * NEWS: Typo.
984 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
986 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
987 in URLs to improve DVI formatted output (requires texinfo 4.6).
988 (System Services, Systemology, Shellology): Likewise.
989 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
990 output.
992 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
993 continuous text.
994 (Runtime): Fix macro argument names to match description:
995 `action-if-found' -> `action-if-true' and similarly.
996 (Obsolete Macros): Likewise.
997 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
998 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
999 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1001 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1003 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1005 * ChangeLog: Typo.
1006 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1007 DVI output.
1009 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1011 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
1012 /bin/sh set unsorted output.
1013 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
1014 * tests/local.at: Likewise.
1016 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
1018 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
1019 (Integer Overflow, Null Pointers, Buffer Overruns):
1020 (Floating Point Portability, Exiting Portably): New sections.
1021 (Writing Test Programs): Fix some langauge. Recommend exiting
1022 with status 1, not merely nonzero. Clarify exit declaration.
1023 (Run Time): Move C exit status stuff to new Exiting Portably section.
1024 (Systemology): Mention Posix and levenez. Update v7 reference.
1025 (Portable Shell): Mention the Posix shell.
1027 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1029 * bin/autoconf.as (me): Replace by as_me.
1031 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1033 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1034 since as_me isn't set yet.
1036 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1038 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1039 a few minor bugs in this area.
1041 * doc/autoconf.texi (Programming in M4sh): Comment out the
1042 documentation of AS_BASENAME, for now.
1043 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1044 (Limitations of Builtins) <basename>: Do not refer to
1045 AS_BASENAME.
1046 * bin/autoconf.as (me): Don't use AS_BASENAME.
1047 (dir): Remove the unused variable.
1048 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
1049 AS_DETECT_REQUIRED. All uses changed.
1050 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
1051 All uses changed.
1052 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
1053 (AS_BASENAME): Use "basename --" to protect against leading "-".
1054 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
1055 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1056 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
1057 (_AS_DIRNAME_PREPARE): Likewise.
1058 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
1059 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
1060 (AS_DIRNAME): Use "dirname --".
1062 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1064 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1065 of "run time" and "run-time" changed to "runtime", for consistency.
1066 * lib/autoconf/fortran.m4: Likewise (in comment).
1067 * lib/autoconf/functions.m4: Likewise.
1068 * lib/autoconf/general.m4: Likewise.
1069 * lib/autoconf/headers.m4: Likewise.
1071 * doc/autoconf.texi (Run Time): Document the exit status situation
1072 with more accuracy and detail.
1074 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1076 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1077 Archive is not officially `GNU' any more. Update URL.
1078 (Defining Directories): Likewise
1079 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1081 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1083 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1084 newline from the `trap' code to finish `config.log'; the NetBSD
1085 /bin/sh resets the exit status after an empty command, as
1086 documented in doc/autoconf.texi.
1087 Reported by Dalibor Topic <robilad@kaffe.org>.
1089 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1091 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1092 Suggested by Bruno Haible.
1094 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1096 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1097 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1098 Instead, just list the shells that we know work.
1099 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1100 changed. Be more cautious about the _cv_ variable.
1101 * tests/tools.at (Syntax of the shell scripts): Check the
1102 _cv_ variable once, at first, to avoid an internal autoconf error
1103 when sh -n does not work.
1105 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1107 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1109 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1111 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1112 use ">&-" since we're only 99.999% sure that this is portable,
1113 and since the MinGW bug is fixed in a different way.
1114 * lib/autotest/general.m4 (AT_INIT): Likewise.
1116 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1118 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1119 before opening config.log, to avoid hitting a bug on MinGW.
1121 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1123 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1124 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1125 This works around a MinGW bug reported by Eric Paire.
1126 Make sure that all writes to the log file append to it,
1127 rather than possibly losing data.
1128 * lib/autotest/general.m4 (AT_INIT): Likewise.
1130 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1132 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1133 description.
1135 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1137 * NEWS: Update.
1139 * configure.ac (AC_INIT): Bump to 2.59d.
1141 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1143 Version 2.59c.
1145 * Makefile.maint (news-date-check): Do not require a leading `*'
1146 before the release date in NEWS.
1148 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1149 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1151 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1152 the instantiated file do not contain the string 'datarootdir'
1153 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1154 @mandir@, replace the reference '${datarootdir}' by the value.
1155 * tests/torture.at (datarootdir workaround): New test.
1156 * NEWS: Advertise this temporary fixup.
1157 Based on a patch by Bruno Haible, reported and analyzed by
1158 Paul Eggert and Noah Misch.
1160 2006-04-12 Eric Blake <ebb9@byu.net>
1162 * tests/autotest.at (Debugging a failed test): Fix comment.
1164 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1166 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1167 all the changes since 2006-04-07.
1169 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1171 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1172 succeeded, but `ln -s file dir' failed, take care to remove the
1173 leftover target before the next test, to prevent its spurious
1174 failure; also make sure `ln file dir' works before selecting it.
1175 Thanks to Keith Marshall for pointing this out.
1176 * THANKS: Update.
1178 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1179 assignments in `at_debug_args', so that we put them correctly
1180 in the `run' script.
1181 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1182 Reported by Eric Blake.
1184 2006-04-11 Eric Blake <ebb9@byu.net>
1186 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1187 top-level tests after micro-suite has been run. Used in...
1188 (Debugging a successful test, Debugging script and environment),
1189 (Debugging a failed test): ...these new tests. The first of these
1190 is fixed by...
1191 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1192 macro, split out from...
1193 (AT_INIT): ...here, so that using -d also generates a run script.
1194 Document that -d inhibits top-level logging.
1195 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1196 inhibits top-level logging; debug scripts are created.
1198 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1199 check.
1200 * tests/autotest.at (Empty test, Empty check): New test to check it.
1202 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1203 from gcc.
1205 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1207 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1208 the files if a problem appears. Make the empty *.at files
1209 read-only, too. Proposed by Ralf Wildenhues.
1211 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1213 * config/Makefile.am: Add comment to force updated Makefile.in.
1215 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1216 space only patch to this file, this patch causes the Makefile.in
1217 files that include freeze.mk to be updated, and thus have a
1218 newer time stamp again, which in turn makes a pristine CVS
1219 checkout have correct time stamps.
1221 * Makefile.maint (cvs-sv): New macro, to be used..
1222 (config.guess-url_prefix, config.sub-url_prefix)
1223 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1224 point to CVS text checkout of Gnulib files.
1225 (copyright-check): Bump current year.
1226 (announcement): Do not hard-wire `./announce-gen'.
1227 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1228 correctly.
1229 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1230 `chmod +x'.
1231 (wget_files): Update config.guess, config.sub, texinfo.tex by
1232 `wget-update', now that their URLs work again.
1234 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1236 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1237 Problem noted by Paul D. Smith.
1239 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1241 * doc/autoconf.texi: Remove unused words from word list.
1242 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1243 .x-sc_trailing_space: New files.
1245 * doc/standards.texi: Sync from gnulib.
1247 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1248 `LIBOBJDIR' as experimental.
1250 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1251 with a target directory; it's internally implemented as `cp'
1252 anyway, but since Autoconf advertises the possibility to use
1253 a target directory when LN_S is `ln -s', we need to find out.
1254 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1255 analyzed by Keith Marshall <keith.marshall@total.com>.
1257 * THANKS: Update.
1259 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1261 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1262 confdefs.h as-is. In general, if it has backslash-newline or the
1263 like, then it doesn't work either to sort or to remove empty
1264 lines.
1266 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1268 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1270 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1272 * lib/autom4te.in (Automake-preselections): Preselect
1273 _AM_SUBST_NOTMAKE.
1275 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1277 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1278 apostrophe within a single-quoted string, as this is the usual
1279 tradition and is easier to read than '"'"'. Don't rely on the
1280 shell treating "$/" like '$/'. Use a more-consistent indenting
1281 style for the trap.
1283 2006-04-09 Eric Blake <ebb9@byu.net>
1285 * tests/autotest.at (Backquote command substitution),
1286 (Multiline backquote command substitution): Remove mistaken
1287 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1288 applied...
1289 (Parenthetical command substitution, Multiline parenthetical
1290 command substitution): here.
1292 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1294 Import macros from gnulib (often changing their name).
1296 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
1297 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
1298 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
1299 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,

1308 (Pointers): Add Gnulib URL.
1309 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
1310 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
1311 Gnulib section.
1312 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
1313 suggest a #define rather than a typedef for _Bool, and mention
1314 Gnulib rather than trying to substitute stdbool code.
1315 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
1316 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
1317 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
1318 AC_STRUCT_DIRENT_D_TYPE.
1319 (Particular Types): Mention stdint.h and inttypes.h as standard
1320 headers too.
1321 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
1322 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
1323 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
1324 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
1325 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1326 (C Compiler): Move AC_C_LONG_DOUBLE to ...
1327 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
1328 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
1329 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
1330 (Coding Style). Don't mention m4_expand_once.
1331 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
1332 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
1333 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
1334 (AC_CHECK_FUNCS): Use it.
1335 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
1336 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
1337 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
1338 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
1339 (AC_HEADER_ASSERT): New macro.
1340 (AC_HEADER_STDBOOL): Don't assume "#error" works.
1341 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
1342 Catch a bug in an HP-UX C compiler.
1343 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
1344 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
1345 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

1347 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
1348 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
1349 New macros.
1351 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
1352 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
1354 2006-04-08 Stepan Kasal <kasal@ucw.cz>
1356 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
1357 of the warning introduced by the 2001-08-28 change.
1359 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
1360 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1362 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
1363 variables shall be overriden by the cache.

1365 that contains braces.
1367 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1369 Revert the patch from 2006-04-01 and only improve
1370 _AS_DETECT_BETTER_SHELL:
1372 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1373 skip nonexistent directories.
1374 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1375 only shell candidates which exist.
1376 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1377 * lib/autotest/general.m4 (AT_INIT): No need to give three
1378 parameters to _AS_PATH_WALK.
1380 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1381 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1383 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1384 distinguish m4sugar macros.
1385 * tests/tools.at (autoupdating with aclocal and m4_include):
1386 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1387 test case by Noah Misch <noah@cs.caltech.edu>.
1389 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1391 Revert my change from 2006-03-17, in other words:
1392 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1393 and DUALCASE=1.
1394 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1395 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1396 it is set.
1398 2006-04-07 Eric Blake <ebb9@byu.net>
1400 * doc/autoconf.texi (Programming in M4sh): Document that
1401 AS_MKDIR_P exits the script on failure.
1402 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1404 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1406 * config/elisp-comp, config/install-sh, config/mdate-sh,
1407 config/missing, config/mkinstalldirs: Sync from Automake.
1409 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
1410 from Automake.
1412 * doc/make-stds.texi: Sync from gnulib.
1414 2006-04-06 Eric Blake <ebb9@byu.net>
1416 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1417 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1418 2006-04-01.
1420 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
1421 Eric Blake <ebb9@byu.net>,
1422 Paul Eggert <eggert@cs.ucla.edu>,
1423 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1425 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1426 whether `set' quotes correctly: redirect stderr of the tested
1427 `set', and use a subshell, for Ultrix; use `sed' instead of
1428 `grep' for zsh `set' which may write binary output; match only
1429 at the beginning of a line, to avoid false positives.
1430 In order to avoid false positives by unrelated variables with
1431 multiline content, put the dump algorithm in a subshell and
1432 unset all variables containing newlines (except some which are
1433 special to the shell). Warn about cache variables that are
1434 unset.
1436 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1438 * config/config.guess, config/config.sub, config/texinfo.tex:
1439 Sync from upstream.
1441 * tests/mktests.sh: Reword comments.
1443 * tests/mktests.sh: Only skip internal macros starting with
1444 `_AC_' or `__AC_'. Noted by Stepan Kasal.
1445 Update exclusion lists for the test suite to this end:
1446 (AC_ARG_VAR): Do test this now.
1447 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
1448 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
1449 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
1450 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1452 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1453 shell issue with double-quoted command substitutions of native
1454 commands.
1455 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
1456 Marshall.
1458 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
1459 no file matches the glob, discard the warning, set `nullglob'.
1460 (syntax-check): Likewise.
1461 (sc_cast_of_x_alloc_return_value): Likewise.
1462 (sc_cast_of_alloca_return_value, sc_error_exit_success)

1466 (sc_tight_scope): Do not fail for non-existing `src' directory.
1467 (sc_changelog): Skip the Copyright footer.
1468 * lib/autoconf/lang.m4: Remove trailing space.
1470 * lib/autoconf/status.m4: More replacements to
1471 <tab><space> where this makes sense.
1473 2006-04-06 Stepan Kasal <kasal@ucw.cz>
1475 * tests/Makefile.am (maintainer-check-posix):
1476 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
1478 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1479 ac_config_<foo>s again, sometimes normalized, sometimes not.
1480 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1481 (AC_CONFIG_COMMANDS): Do not do so here.
1482 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1483 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1484 2005-07-25 rewrite. Noticed by Noah Misch.
1486 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1487 _AC_PRESERVE_HELP_ORDER, ...
1488 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1490 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1491 inside m4_expand_once; it is redundant.
1493 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
1494 for --help from Cygnus `configure.'
1496 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
1498 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
1499 on a patch proposed by Ralf Wildenhues.
1501 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1503 * lib/autoconf/status.m4: Replace <space>''<tab> with
1504 <tab><space> where this makes sense.
1506 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
1507 Noah Misch <noah@cs.caltech.edu>
1509 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
1510 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
1511 * doc/autoconf.texi (Help Formatting): New node.
1512 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
1514 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1516 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
1517 lib/autoconf/specific.m4, lib/autoconf/status.m4,
1518 lib/autoconf/types.m4, lib/autotest/general.m4,
1519 tests/mktests.sh, tests/torture.at: White space cleanup:
1520 remove some SPACE before TAB, or add quoting ('' or @&t@).
1522 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
1524 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
1526 2006-04-05 Eric Blake <ebb9@byu.net>
1528 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
1529 empty test suite works.
1530 * tests/autotest.at (Empty test suite): Remove xfail.
1532 2006-04-05 Noah Misch <noah@cs.caltech.edu>
1534 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
1535 TAGS to ac_config_<foo>s.
1536 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
1537 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
1538 normalizing it, consistent it with previous releases.
1539 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
1541 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1543 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
1544 Use simplified args that Eric Blake originally suggested.
1546 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
1548 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
1549 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
1550 Use 'comm' rather than N instances of grep; this also fixes a bug
1551 whereby substrings were incorrectly matched, causing us to not
1552 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
1553 (exclude_list): Exclude empty macros.
1554 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
1556 Use awk rather than grep -E or egrep, to avoid
1557 portability problems with regular expressions containing newlines.

1559 Switch from grep to awk syntax.
1560 (ac_exclude_script): Renamed from ac_exclude_egrep.
1561 (au_exclude_script): Renamed from au_exclude_egrep.
1563 2006-04-04 Noah Misch <noah@cs.caltech.edu>
1565 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
1566 a subdirectory subject to Cygnus `configure'.
1567 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
1569 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
1570 report request when we have no AC_PACKAGE_BUGREPORT.
1572 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1574 * THANKS: Update.

1577 generated files.
1579 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
1580 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
1581 typedef'ed restricted pointer, to catch a compiler bug on
1582 HP-UX 11.x, and fix warnings so it passes with -Werror.
1583 (_AC_PROG_CC_C99): Likewise.
1584 Reported by Albert Chin <china@thewrittenword.com>.
1585 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

1591 (output): Emit AC_CONFIG_SUBDIRS as needed.
1592 * tests/autoscan.at (autoscan): Remove XFAIL.
1594 2006-04-03 Noah Misch <noah@cs.caltech.edu>

1600 * THANKS: Add myself.
1602 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1604 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
1605 to log, point to testsuite output tree.
1607 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
1609 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
1610 * doc/autoconf.texi (Function Portability): Mention that C++
1611 has trouble with 'exit'.

1614 Remove; all uses removed.
1615 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

1635 Clean up _AC_COMPILER_EXEEXT* macros.
1637 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1638 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1639 ac_file to the name of the default output file and call
1640 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1641 initial `rm' of the candidate files...
1642 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1643 the same list in subsequent `rm' calls, and for the temporary
1644 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1645 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1646 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1647 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1648 no longer needed) by libtool. Make it a cache check.
1649 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1650 copied here by mistake.
1651 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1652 _AC_COMPILER_EXEEXT.
1653 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1654 _AC_COMPILER_OBJEXT directly.

1685 * lib/autoconf/general.m4 (_AC_INIT_VERSION): Emit script name and
1686 Autoconf version number despite a zero- or one-argument AC_INIT.
1688 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
1689 subordinate tools.
1690 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
1691 * doc/autoconf.texi (autoreconf Invocation): Document it.
1693 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
1694 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

1700 rm failed to remove it.
1702 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1704 * bin/autoupdate.in: Redefine m4_location so that warnings print
1705 the correct lines of the input file by subtracting..
1706 (_au__first_line): ..this new definition.
1708 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
1709 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
1710 Remove stray newline in output.
1711 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
1712 AC_DEFUN this for autoconf, including the obsoletion diagnose.
1713 Fixes autoupdating of code where the replacement output contains
1714 m4sugar macros.
1715 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
1716 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

1718 * tests/tools.at: Several new tests for all of this.
1719 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
1720 hairy details.
1721 The AC_LANG_SAVE issue was reported against Libtool by
1722 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
1723 Kristian Kvilekval <kris@cs.ucsb.edu>.
1725 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1727 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
1728 switch all of them on and of when necessary. Fixes the bug when
1729 m4sugar macros (e.g., m4_define) were expanded after the first
1730 automatic update (e.g., after AC_PREREQ or AC_INIT).
1732 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

1754 2006-03-30 Chris Pickett <cpicke@cs.mcgill.ca> (tiny change)
1756 * doc/autoconf.texi (autoreconf Invocation): Mention that -I for
1757 aclocal cannot be given on the command line.
1759 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
1761 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
1762 Give an example for AS_DIRNAME instead of referring to Posix..
1763 (File System Conventions): Put discussion of // versus / here, and
1764 modernize it a bit.
1765 (Limitations of Usual Tools): Add basename. Remove verbiage
1766 after dirname, since it got moved to the above sections.
1767 All this was inspired by a patch proposed earlier by Eric Blake.
1769 2006-03-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1771 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Quote

1773 * lib/autotest/general.m4 (AT_INIT): Likewise.
1774 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Likewise, for
1775 `$0', $as_me.
1777 2006-03-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1779 * bin/autoscan.in: The value of find_configure_ac should be
1780 checked for existence, so we don't barf over a nonexisting
1781 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
1783 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1785 * bin/autoupdate.in: Fix some typos.
1787 2006-03-21 Stepan Kasal <kasal@ucw.cz>
1789 * doc/autoconf.texi (Installation Directory Variables): Fix typo.
1791 * lib/autoscan/autoscan.list: Refreshed.
1793 2006-03-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1795 * tests/local.at (AT_CHECK_ENV): Ignore AC_SUBSTed Objective C
1796 and Erlang related variables.

2276 our own style advice re 's,a,b,' versus 's|a|b|'. Use "Sed"
2277 rather than "sed" when talking about Sed in general.
2278 (Particular Programs): Likewise.
2279 (Coding Style): y is like s with respect to / and ,.
2280 (Limitations of Usual Tools): Document the weird restrictions
2281 that Posix has about { }. Use better quoting.
2282 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_HEADER):
2283 Rewrite to conform to Posix rules about { } in sed scripts.
2284 * lib/m4sugar/m4sh.m4 (AS_DIRNAME_SED, AS_BASENAME_SED): Likewise.
2285 * tests/foreign.at (Libtool): Likewise.
2286 * tests/semantics.at (AC_CHECK_PROG & AC_CHECK_PROGS):
2287 Use our own style advice re 's,a,b,' versus 's|a|b|'.

2302 shell from zsh to bash.
2304 2005-12-31 Stepan Kasal <kasal@ucw.cz>
2306 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Use $PATH_SEPARATOR;
2307 ":" caused problems on OS/2-EMX. Suggested by Andrew Belov.
2309 2005-12-29 Paul Eggert <eggert@cs.ucla.edu>
2311 * doc/autoconf.texi (Shell Substitutions): Warn about unbalanced
2312 parentheses in $(...). Problem reported by Eric Blake.

2340 (Limitations of Builtins): Likewise.
2342 2005-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2344 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Pass
2345 CONFIG_SHELL in the environment of the configure rerun.
2346 * doc/autoconf.texi (Here-Documents, config.status Invocation):
2347 Suggest passing CONFIG_SHELL absolute, and in the environment
2348 rather than as option.
2350 2005-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2352 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2353 Fix quoting of output line (triggered for many AC_SUBST_FILEs).

2363 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
2364 ac_clean_files and LIBOBJS.
2366 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2368 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
2369 Factor functionality to..
2370 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
2371 `AC_SUBST($1)' in the public version.
2372 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
2373 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
2374 ac_pt_* variables.
2376 2005-11-01 Stepan Kasal <kasal@ucw.cz>
2378 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
2379 filesystems.
2381 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2385 2005-10-27 Stepan Kasal <kasal@ucw.cz>
2387 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
2388 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
2390 2005-10-25 Stepan Kasal <kasal@ucw.cz>
2392 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
2393 conftst2.$ac_objext.
2394 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
2396 2005-10-24 Stepan Kasal <kasal@ucw.cz>
2398 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
2399 conftest.o, to see whether the compiler really obeys; rm the object
2400 file before and after the test and register it with ac_clean_files.
2401 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
2403 2005-10-21 Stepan Kasal <kasal@ucw.cz>
2405 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
2406 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
2407 code so that the most common case requires less forks.
2409 2005-10-20 Stepan Kasal <kasal@ucw.cz>
2411 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is

2419 the latter'', in two places.
2421 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
2423 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
2424 AC_LANG_PROGRAM, fixing a typo. Don't give details about
2425 the inner workings of AC_LANG_FUNC_LINK_TRY.
2426 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2427 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2428 by the function rather than ignoring it.
2429 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2430 comparing its address. Intel's interprocedural optimization was
2431 outsmarting the old heuristic. Problem reported by
2432 Mikulas Patocka.
2434 2005-10-19 Stepan Kasal <kasal@ucw.cz>
2436 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
2438 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
2440 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

2443 2005-10-04 Stepan Kasal <kasal@ucw.cz>
2445 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
2446 before removing it (chmod -R u+rwx); there are three instances of this.
2448 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2449 Stepan Kasal <kasal@ucw.cz>
2451 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2452 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2453 make its content writable before removing it. Remove an errorneous
2454 comment from the end, where the logs of the failed tests are copied
2455 to the main log file.
2457 2005-09-27 Stepan Kasal <kasal@ucw.cz>
2459 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
2460 in case the computer is too quick. Double quote the configure.ac
2461 snippets.
2463 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
2464 problems if the testsuite were running too fast.
2466 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2468 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2469 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2470 (which belong to Xt, not X itself). See Debian bug 327655.
2471 * NEWS: Mention this.
2473 2005-09-07 Stepan Kasal <kasal@ucw.cz>
2475 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
2477 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
2479 * config/move-if-change: Don't output "$2 is unchanged";
2480 suggested by Ben Elliston. Handle weird characters correctly.
2482 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2484 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2485 calls, so that the final expansion of this macro is shorter.
2486 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2487 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2488 the cleanup there. Use AS_VAR_* macros, to be more general.
2489 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2491 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2493 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
2495 2005-09-01 Stepan Kasal <kasal@ucw.cz>
2497 * doc/autoconf.texi (Configuration Headers): Add an index entry
2498 for AH_HEADER.
2500 2005-08-26 Pavel Roskin <proski@gnu.org>
2502 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
2503 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
2504 running xmkmf.
2506 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
2508 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2509 The previous patch didn't work, so try a better one.
2511 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2513 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2514 in the example. Reported by Bruno Haible.
2515 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2516 "if $undefined_var;" succeeds with my shell.
2518 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2519 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2520 but change the m4_divert_text to m4_divert_once.
2522 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2524 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2525 Work around bug in Solaris /usr/xpg4/bin/awk.
2526 The bug is present in at least Solaris 8 through 10.
2528 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2530 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2531 some evil values and relying on the fact that $* concatenates the
2532 parameters by the first character from IFS.
2534 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2535 Stepan Kasal <kasal@ucw.cz>
2537 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2538 first header appears, define AH_HEADER.
2539 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2540 Update limitations about when to call AC_CONFIG_HEADERS.
2541 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2542 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2543 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2544 ``Configuration Actions''; fix their index entries.
2546 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2547 options correctly. Process N-M as M-N if M is smaller than N.
2548 Process ranges correctly so that N-N will run only N.
2549 Sort and uniquify the tests that will be run. If there is more
2550 than one test, reinsert the banners for the tests.
2551 * tests/autotest.at (Keywords): Unmark XFAIL.
2553 2005-08-23 Stepan Kasal <kasal@ucw.cz>
2555 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
2556 before passing the macro name to AH_TEMPLATE.
2558 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2559 now opens log after option processing; in particular, --version
2560 and --help do not touch config.log.
2562 * Makefile.maint: Revert the change from 2005-08-12.
2564 2005-08-22 Stepan Kasal <kasal@ucw.cz>
2566 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
2567 common code to...
2568 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
2570 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2572 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
2573 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
2574 Language cleanup.
2576 * doc/autoconf.texi (Defining Symbols, Changed Results):
2577 Prepend to LIBS, not append, in examples.
2579 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2581 When building in place, set srcdir="."; suggested by Tim Van Holder.
2583 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2584 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2585 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2586 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
2587 does not mean "no --srcdir option".
2589 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2591 * tests/autoscan.at (autoscan): New file.
2592 * tests/suite.at: Use it.
2593 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
2594 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
2596 * tests/autotest.at (Keywords): Test keywords combinations.
2598 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2600 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2601 add "2>&1"; gzip 1.2.4 prints help on stderr.
2603 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2605 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2606 was pushdef'ed twice while popped only once. Push it only once.
2607 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2609 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2611 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
2612 prefixed by mere "===", not "configure: === ".
2614 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
2616 * Makefile.maint: Update from Bison.
2618 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2619 "<tab>" in comment, so that the point is understandable.
2621 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2623 Rewrite substantial part of lib/autoconf/status.m4.
2624 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2625 and CONFIG_COMMANDS are not processed in four separate loops.
2626 Instead, there is one main loop. This alows that the common code
2627 is expanded only once, thus config.status (and configure) is smaller.
2629 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2630 the AC_LIST_FILES and cousins macros are no longer used.
2632 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2633 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2634 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2635 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2636 contain the initialization, nor the for loop, nor the associated
2637 commands; all these go to ...
2638 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2639 _AC_OUTPUT_CONFIG_STATUS.
2640 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2641 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2642 (_AC_OUTPUT_FILE): The creation of the sed script ...
2643 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2644 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2645 _AC_OUTPUT_MAIN_LOOP.
2646 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2647 _AC_CONFIG_COMMANDS): Use ...
2648 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2649 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2650 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2651 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2652 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2653 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2654 ... new macros.
2655 (_AC_CONFIG_UNIQUE): Update.
2656 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2657 Replaced by this ...
2658 (_AC_LIST_TAGS): ... new common macro.
2659 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2660 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2661 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2662 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2663 this didn't belong to the `config commands' section.
2664 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2665 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2666 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2667 to the `config commands' section either.
2668 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2669 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2671 ... and many changes to the comments nearby.
2673 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2674 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2675 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2676 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2677 (#define header templates): The comment at the top of the generated
2678 header now includes the name(s) of the source file(s).
2680 Several unrelated small changes:
2682 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2683 parameter to AC_DIAGNOSE.
2684 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2685 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2686 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2687 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2688 with AU::AC_OUTPUT.
2689 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2690 in AC_OUTPUT doesn't double-quote it either.
2691 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2692 parameters.
2694 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2696 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2697 versions of Portland Group compiler produce single- and double-quoted
2698 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
2699 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
2701 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2703 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2704 This is a corrected version of yesterday's patch.
2706 2005-07-07 Stepan Kasal <kasal@ucw.cz>
2708 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
2709 path, too; insert a "===" to emphasize the line.
2711 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
2712 ac_cv_build_alias to ac_build_alias.
2713 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
2715 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2716 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2717 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2718 (AC_ARG_VAR): ... here.
2719 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
2720 target_alias.
2722 Keep a list of all precious variables and process them with one simple
2723 for loop, instead of expanding all commands, or, OTOH, complicated
2724 processing of output of "set".
2725 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
2726 variable names in new macro...
2727 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
2728 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
2729 a loop to assign all ac_env_* and ac_cv_env_* variables.
2730 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
2731 to INIT_PREPARE.
2732 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
2733 its value to shell variable ac_precious_vars and call
2734 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.

2774 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2776 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

2786 configure_input, top_builddir, srcdir, etc.
2787 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2788 PATH_SEPARATOR in AUTOTEST_PATH.

2798 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

2823 Likewise for --header; moreover, recognize --he and --h as shortcuts
2824 for --help in that case.
2826 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2827 matches the order of execution. No code changed.

2849 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
2850 (AC_SUBST): Call it.
2851 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2852 the directory specific variables; but don't call it for configure_input.
2854 2005-06-28 Derek Price <derek@ximbiot.com>
2856 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2857 addition.
2859 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

2862 directory have inherent problems with special characters like spaces,
2863 due to limitations in Make syntax. Problem reported by Alexandre
2864 Duret-Lutz.

2881 because we really don't support spaces and suchlike in dir names.
2882 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2883 Don't worry about backslashes in srcdir; it can't happen now.

2910 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
2911 b, t, r, w commands require single space, while : cannot have any.
2912 (Special Shell Variables): Fix sed code this in the example.
2913 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2914 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
2916 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
2917 expand to the empty list. Don't use two pairs of m4_changequote,
2918 it's not necessary.

2926 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
2927 * doc/autoconf.texi:
2928 Don't mention Solaris versions so much, if a
2929 problem is common to all extant versions of Solaris. Say "SunOS
2930 4" instead of "SunOS" for SunOS 4.
2931 (awk): Mention more of the limitations of traditional Awk.
2932 (cat): Don't talk about cat -v.
2934 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

2939 to be compatible with glibc strverscmp.
2940 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
2942 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

2954 as per POSIX.
2955 * lib/m4sugar/m4sh.m4: Likewise.

2959 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
2960 (.x.1): Ignore the time stamp in the .TH line when deciding whether

2964 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
2965 quotes and backslashes. Patch from Derek Price.

2970 AS_TR_SH.
2972 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
2974 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
2975 -u, since it outputs chatter if the input files are the same.
2976 Problem reported by Ralf Menzel.
2978 2005-06-08 Derek Price <derek@ximbiot.com>
2980 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
2981 renaming them since they are about to be redefined anyhow.
2983 2005-06-08 Derek Price <derek@ximbiot.com>
2985 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
2986 redefined M4 macros to this node. Document m4_include & m4_sinclude.
2987 Move m4_undefine to alphabetical order.
2989 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
2991 * README: Recommend GNU M4 1.4.3 or later.
2992 * doc/autoconf.texi (Introduction): Likewise.
2993 Reword to avoid some formatting glitches.
2994 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.

2996 Redo example output tp match current CVS snapshot.
2997 Use @example.org in email addresses when the examples
2998 might get inadvertently cut-and-pasted into user code.
2999 Remove example of autom4te usage that doesn't seem to work now.
3000 Use modern AC_INIT (except when the example is meant to be
3001 shown with Autoconf 2.13).
3002 Update ksh info for Solaris 9 and later.
3003 KB -> kB.
3004 Modernize description of Automake versions a bit.
3005 Don't claim a future version of Autoconf is near.

3011 follows its own advice about quoting better.
3012 Reword to avoid some formatting glitches.
3013 * doc/installt.exi: Reword to avoid some formatting glitches.
3015 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3016 Tru64 ksh pattern matching bug. Reported against Libtool by
3017 Albert Chin <libtool@mlists.thewrittenword.com> and
3018 Nicolas Joly <njoly@pasteur.fr>.
3020 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3022 m4_cdr of one-member list was [[]] (one-member list containing an
3023 empty string) instead of [] (an empty list. Callers were skewed to
3024 match this misbehaviour. As a consequence of this:
3025 - m4_foreach([x], [], [foo]) expanded to `foo', while
3026 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3027 This bug has been fixed:
3029 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3030 expand to an empty string; print error msg if called without
3031 an argument list.
3032 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3033 misbehaviour; handle [] and [[]] correctly.

3041 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3043 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3044 swallow records with more than 99 fields.
3045 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3046 parse the long line.
3048 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3050 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3051 swallow literals longer than 399. Reported by Ralf Wildenhues.

3063 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3064 (DISTCLEANFILES): Remove $(check_SCRIPTS).

3069 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3070 expression of unbounded size when processing the --list
3071 option. This runs afoul of a limit of 399 bytes per regular
3072 expression on AIX. Problem reported by Ralf Wildenhues.

3081 Reword description of line replacement.
3083 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3085 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3086 now contain newlines, and substituted files must be referenced on
3087 a line alone; the sed scripts to substitute them are now very
3088 different.
3089 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3090 commands can be put in a sed script portably.
3091 * doc/autoconf.texi (Setting Output Variables): Document above

3104 classes in shell scripts. The test was too brittle.
3106 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3108 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

3122 messages when ac_unique_file is not found.
3123 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3124 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo

3140 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3141 (ac_top_builddir): ... this ...
3142 (ac_top_build_prefix): ... to this; the old name is also kept, for
3143 backward compatibility.
3144 (ac_top_builddir_sub): New variable, without the trailing slash,
3145 always nonempty.
3146 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

3160 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3161 argument to m4_foreach. I guess it was necessary in the past,
3162 but I think it's a no-op now.
3164 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3166 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3167 ``cat <<_ACEOF'' commands to one.

3227 check.
3228 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
3229 enough arguments, similarly as in m4_bpatsubsts.
3231 2005-05-12 Stepan Kasal <kasal@ucw.cz>
3233 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

3236 2005-05-11 Stepan Kasal <kasal@ucw.cz>
3238 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
3239 for absolute directory names in one loop.
3240 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
3241 abbreviations of --version and --debug.
3243 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
3245 * doc/autoconf.texi (Autoconf Language): Be more precise about
3246 quoting rules. Problems noted by Stepan Kasal.
3247 Also, throughout this document, be more careful about white space.
3248 "blank", "white space", and "space" all have different meanings
3249 and we should be careful to say what we mean.
3251 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3253 Fix C++ related problems reported by Werner Lemberg.
3254 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
3255 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
3256 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
3257 avoid problems with C++ and throw.
3258 * tests/compile.at: .cpp, not .cc.
3260 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
3262 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3264 * doc/autoconf.texi (Generic Functions): Typos.
3266 2005-05-02 Gary V. Vaughan <gary@gnu.org>
3268 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
3269 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
3270 set by latest automake.
3272 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
3274 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
3275 outputs 0 on GNU/Linux these days.
3277 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
3279 * doc/autoconf.texi (Autoconf Language): Add more description
3280 about quoting heuristics.
3281 (Limitations of Builtins): Describe "set -" problems.
3283 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3285 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
3286 not newline.
3288 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
3289 by AC_DEFINE; it was a mistake.
3290 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
3292 2005-04-25 Stepan Kasal <kasal@ucw.cz>
3294 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
3296 2005-04-22 Stepan Kasal <kasal@ucw.cz>
3298 * doc/autoconf.texi (External Software): Quadrigraphs are not
3299 processed correctly in AS_HELP_STRING; avoid this in the examples.
3300 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3301 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3302 comment and reduce m4_default([foo], []) to [foo].
3303 (m4_strip): Update the explanation.
3305 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3307 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3308 Remove core.conftest.* too; it's generated by Tru64 5.1.
3309 Problem reported by Jennis Pruett.
3310 * lib/autoconf/functions.m4
3311 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3312 Don't bother to remove core files; AC_RUN_IFELSE should do that
3313 for you.
3315 2005-04-19 Stepan Kasal <kasal@ucw.cz>
3317 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

3327 the comment.
3329 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
3331 * doc/autoconf.texi (External Software, Package Options): Add
3332 examples showing how to implement --with-* and --enable-* options.
3334 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
3336 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
3337 as well as configure.in. Problem reported by Gregorio Guidi.
3339 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3341 * doc/autoconf.texi (Particular Functions): Use gnulib's current
3342 pattern for alloca snippet.
3344 2005-04-04 Stepan Kasal <kasal@ucw.cz>
3346 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

3352 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
3354 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
3355 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
3357 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3359 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3360 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3361 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3362 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3363 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3365 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3367 * NEWS: The configure command now warns you if you attempt to use
3368 a directory whose name contains a special character like space,
3369 newline, or "\".
3370 * doc/autoconf.texi (Installation Directory Variables): Allow
3371 "," in file names. Do not use \@; it's not a portable regexp.
3372 * bin/Makefile.am (edit): Likewise.
3373 * lib/Makefile.am (edit): Likewise.
3374 * tests/Makefile.am (edit): Likewise.
3375 * tests/semantics.at: Likewise.
3376 * tests/torture.at: Likewise.
3377 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3378 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3379 * doc/autoconf.texi (File System Conventions): Warn about
3380 unportable file names.
3381 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3382 (AC_INIT): Use it.
3383 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3384 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3385 ac_pwd, and quote srcdir.
3386 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3388 * doc/autoconf.texi: Fix some systematic formatting problems.
3389 ".)" needs a following @: if not at the end of a sentence, and
3390 similarly for "!)". "etc." should be preceded by a comma.
3391 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3393 2005-03-22 Bruno Haible <bruno@clisp.org>
3395 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3396 argument is often called 'build-aux'.
3398 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3400 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3401 macro AC_TRY_LINK is obsolete.
3402 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3403 `AC_CONFIG_FILES'.
3405 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3407 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3408 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3409 from a Common Lisp's `cl'.
3410 (AC_PROG_CXX): Behave according to the documentation: don't
3411 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3412 make the variable CCC precious; use `cl.exe', not `cl'.
3414 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3415 Alexandre Duret-Lutz <adl@gnu.org>
3417 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3418 /dev/null, as "configure" shouldn't read stdin, and this insulates
3419 us from problems (e.g., when testing for "cl"). Also, do this
3420 redirection before invoking "hostname" or "uname", and keep the
3421 original input stream available via...
3422 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3423 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3424 bother with "</dev/null" since it's now done at the top of
3425 'configure'.
3426 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3427 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3428 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3429 * doc/autoconf.texi (File Descriptor Macros): New section.
3430 (Printing Messages): Mention it.
3431 * tests/base.at (Input/Output): New test.
3433 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3435 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3436 newline if neither \c nor -n work, as that would output two
3437 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3439 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3441 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3442 This causes that any required macros inside will get before the if.
3443 * doc/autoconf.texi (autom4te.cache): A typo.
3445 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3447 Undo previous change, except keep the change to
3448 lib/autoconf/programs.m4 that replaced grep with shell
3449 pattern-matching. This is because net-snmp configure reads stdin.
3450 Reported by Noah Misch.
3452 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3454 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3455 from /dev/null, as "configure" shouldn't read stdin, and this
3456 insulates us from problems (e.g., when testing for "cl").
3457 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3458 before invoking "hostname" or "uname".
3459 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3460 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3461 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3462 "</dev/null" since it's now done at the top of 'configure'.
3463 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3464 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3465 Also, replace grep with shell pattern-matching, to save a process.
3467 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3469 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3470 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3471 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3472 compiler.
3474 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3476 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3477 grep -q isn't portable. Improve grep -s explanation.
3478 Problem reported by Dan Manthey.
3480 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3482 * doc/autoconf.texi (Special Shell Variables): Clarify
3483 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3485 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3487 * doc/autoconf.texi: Use @acronym for DJGPP.
3488 Fix some @code's that should have been @env's, and vice versa.
3489 Sort environment variable names.
3490 Mention that shells no longer inherit IFS.
3491 Don't recommend PATH_SEPARATOR=';' so strongly.
3492 Mention that $RANDOM might expand to the empty string.
3493 "symlink" and "soft link" -> "symbolic link".
3494 Improve mktemp description (reported by Bruno Haible).
3496 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3498 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
3499 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
3500 Likewise.
3501 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
3502 Likewise.
3504 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
3506 * NEWS: Mention AT_COPYRIGHT.
3508 * tests/local.at (AT_CMP): Use diff directly on input files rather
3509 than copying them.
3511 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
3512 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
3514 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3515 and Paul Eggert <eggert@cs.ucla.edu>
3517 * tests/autotest.at (Empty test suite): New test.
3518 * tests/torture.at (Substitute and define special characters)
3519 (Substitute a 2000-byte string, Define to a 2000-byte string)
3520 (Substitute a newline, Define a newline): New tests.
3522 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3524 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
3525 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
3526 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
3527 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
3528 (Standard regular expressions): New test.
3529 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
3530 excess test name quoting.
3531 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
3532 CPPFLAGS to `configure' instead of setting it in `configure'.
3534 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
3535 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
3536 on some platforms.
3538 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
3539 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
3541 * tests/local.at (AT_CMP): New macro.
3542 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
3543 (AC_SAVE_STATE): Move environment grep...
3544 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
3545 (AT_CONFIG_CMP): New macro.
3546 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
3547 * tests/c.at (Extensions): Do not exit early.
3548 * tests/atlocal.in: Inherit $GREP.
3550 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
3551 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
3553 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
3554 (AC_COPYRIGHT): Factor header comment portion out and move into...
3555 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
3556 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
3557 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
3558 --version output.
3559 * tests/local.at: Add Autoconf test suite copyright notice.
3560 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
3562 2005-02-04 Bruno Haible <bruno@clisp.org>
3563 and Paul Eggert <eggert@cs.ucla.edu>
3565 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
3567 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
3569 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
3570 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3572 Try not to generated lines of unlimited length, as POSIX places a
3573 2047-byte limit on line length of portable text files.
3574 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3575 Use newline as a separator, not space.
3576 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
3577 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
3578 space.
3580 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3582 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
3583 as_func_*. Add test to check whether positional parameters
3584 are restored after function return.
3586 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
3588 * doc/autoconf.texi (Special Shell Variables): Mention _,
3589 BIN_SH, DUALCASE. Say that variables other than "status" are safe
3590 if they contain a lower-case letter. The DUALCASE problem was
3591 reported by Ralf Wildenhues.
3593 * bin/autoconf.as: Don't exit with status 0 after write failure
3594 with --help or --version.
3595 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
3596 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
3598 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3600 * doc/autoconf.texi (Limitations of Usual Tools):
3601 Unicos 9 sed limitations.
3602 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
3603 to get the option-enhanced interface on older Crays. Try ftn for
3604 Fortran 95 (newer Crays).
3606 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
3608 * man/Makefile.am (.x.1): Go back to the simple solution, but take
3609 care to echo the commands, so the user knows what's going on.
3610 Modified from a suggestion by Stepan Kasal.
3612 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
3613 with a cross reference. Derived from a suggestion by Bruce Korb.
3615 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
3617 * doc/autoconf.texi (config.status Invocation): Warn about
3618 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
3619 * doc/install.texi (Defining Variables): Likewise.
3620 Based on a proposed patch by Ralf Wildenhues.
3622 * man/Makefile.am (.x.1): Make sure the required generated files
3623 are up to date. Problem and original solution proposed by Stepan Kasal.

3633 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3634 Update the long comment explaining it.
3636 m4_require no longer writes an ``is required by'' line to the
3637 execution stack. It contains only one bit of non-redundant
3638 information: that the macro was required, not called. And even
3639 this bit is useless in most situations: have you ever met a macro
3640 which both calls and requires the same macro?
3642 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3643 (_m4_defun_pro_outer): ... only via this macro, for the outermost
3644 macro.

3646 (m4_expansion_stack_pop): Remove the misplaced comment.
3647 (m4_require): Don't put the ``is required by'' line to the
3648 execution stack; slightly improve the out-of-a-defun error message.

3650 (_m4_require_call): Use it.
3651 * tests/m4sugar.at (m4_require): Expect output without the
3652 ``is required by'' messages.
3654 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
3656 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
3657 rather than x for expr.
3659 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
3660 this is safe.
3661 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
3662 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

3675 support.
3676 * bin/autoheader.in: Pass $force to update_file so that
3677 config.h.in is always recreated when --force.

3688 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
3690 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3691 Warn about newline stripping in `` and $(). Update Solaris
3692 version to 9.

3695 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
3696 stripping.
3698 2005-01-19 Stepan Kasal <kasal@ucw.cz>

3717 reported by Michael Jennings via Daniel Reed; see
3718 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
3720 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
3722 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
3723 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
3724 datadir, infodir, and mandir. Adjust argument parsing code.

3745 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
3746 otherwise.
3747 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
3748 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3749 stored in _m4_divert_diversion or _m4_divert_dump.
3750 (m4_divert_pop): When the parameter is given, compare the symbolic
3751 name with the last diversion pushed on the stack. Previously, the
3752 current diversion was compared with the numeric value of the
3753 diversion given as the parameter.
3754 (m4_require): If the macro hasn't been expanded yet, call ...
3755 (_m4_require_call): this new macro.

3788 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

3790 not essential. Reported by Magnus Therning.
3791 * tests/torture.at (autoreconf.): New banner.
3792 (autoreconf and non-AC configure): Rename to `Non-Autoconf

3841 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
3842 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

3969 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

4034 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>

4037 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
4038 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
4039 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.

4043 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

4054 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
4055 out the common code to ...
4056 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
4057 value of the #define--default to 1, iff the macro was called
4058 with exactly one parameter.
4060 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
4062 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4063 "char c = '\200';" rather than "char c = 0x80;" as the
4064 latter doesn't conform to the strict C standard due to
4065 overflow on signed char hosts.
4067 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
4068 to -qlanglvl=ansi. We don't want to disable extensions.
4070 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
4072 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

4127 2004-11-13 Stepan Kasal <kasal@ucw.cz>
4129 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
4130 the $1_found variable, don't test whether the file is executable;

4132 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
4133 the former ``test -f''.
4134 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
4136 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

4167 * doc/autoconf.texi (auindex): New macro.
4168 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
4169 Problem reported by Stepan Kasal.
4171 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
4173 Fix problems reported by Andreas Buening in:
4174 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
4175 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
4176 in test makefile.
4177 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
4178 readable; it's not true in OS/2-emx.
4180 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
4182 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4183 "/usr/include", clear ac_x_includes instead of leaving it as "no"
4184 (trivial change). Problem and patch reported by Andrew Church in:
4185 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
4187 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

4192 Also, fix some minor spacing and punctuation bugs.
4194 2004-09-02 Akim Demaille <akim@epita.fr>
4196 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and

4212 * README: Add advice about m4 1.4.2.
4214 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
4215 texinfo.tex for now (done by hand now).
4216 * Makefile.maint (wget_files, cvs_files):
4217 Remove ansi2knr.c; nobody uses it.
4218 (ansi2knr.c-url_prefix): Remove.
4219 (cvs-update): Fix test for failure. I don't know why it ever
4220 worked...
4222 * doc/autoconf.texi: Update URLs, some of which went stale.
4223 Use @uref rather than @href.
4225 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
4226 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
4228 * config/config.guess, config/config.sub, config/elisp-comp,
4229 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
4230 doc/fdl.texi, doc/standards.texi: Sync with master copy.
4232 * NEWS, TODO, configure.ac, bin/autoscan.in,
4233 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
4234 doc/install.texi, lib/Autom4te/Configure_ac.pm,
4235 lib/Autom4te/FileUtils.pm, lib/autoconf/general.m4,
4236 lib/autoconf/programs.m4, lib/autoconf/status.m4,
4237 lib/autotest/general.m4, lib/m4sugar/m4sh.m4,
4238 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
4239 tests/tools.at, tests/torture.at:
4240 Use "file name" rather than "filename" or "path",
4241 to be consistent with the terminology of the GNU coding standards.
4243 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
4245 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
4246 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
4247 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
4248 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
4250 More fixes to support spaces in the name of the build directory.
4251 This isn't a complete fix but it's an improvement.
4253 * bin/autoconf.as (autom4te_options): New var.
4254 Use it instead of appending to AUTOM4TE, so that we can allow
4255 spaces in the build directory's absolute name.
4256 * bin/autoheader.in ($autoconf): Allow spaces in file names.
4257 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
4258 AT_CHECK_NOESCAPE): Likewise.
4259 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
4260 main program): Likewise.
4262 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
4264 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
4265 From Ralf Corsepius in:
4266 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
4268 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
4270 * doc/autoconf.texi (Function Portability): Document isinf and
4271 and isnan. From a suggestion by Kevin Ryde.
4273 * lib/Autom4te/General.pm (END): Return correct exit status even
4274 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
4276 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
4278 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4279 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4280 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4282 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4284 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4285 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4286 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4287 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4288 * lib/autom4te.in (Automake-preselections): Preselect
4289 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4291 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4293 * lib/autom4te.in (Automake-preselections): Preselect
4294 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4295 trace them.
4297 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4299 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4300 Tru64.
4301 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4302 Document problem with "`""`" in pdksh POSIX mode.
4304 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4306 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4307 with pdksh, too. Problem reported by Patrick Welche via
4308 Gary V. Vaughan.
4309 * doc/autoconf.texi (Shellology): Note that set -o posix is
4310 useful for pkdsh, too.
4312 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4314 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4315 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4316 Don't fail if ENV or BASH_ENV is readonly.
4317 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4318 etc. are read only. Problem reported by Ludovic Courtes.
4320 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4322 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4323 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4324 (trivial change)
4326 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4328 * doc/autoconf.texi (File System Conventions): Warn about
4329 names like "aux". Problem reported by Eric Blake.
4331 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4332 by zero instead of array size, so that we can use any arithmetic
4333 constant expression (instead of requiring an integer constant
4334 expression). This allows us to test expressions like DBL_MAX <
4335 LDBL_MAX, which didn't conform to the C standard using the old
4336 method.
4337 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4338 now that we can do floating-point tests at compile time.
4340 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4342 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4343 and LDBL_EPSILON, as the resulting expression isn't an
4344 integer constant expression and violates the C standard.
4345 Problem reported by Nelson H. F. Beebe. Also, check
4346 for "L" suffix, and check that long double doesn't have
4347 worse range or precision than double, that mixed-mode
4348 arithmetic doesn't generate a diagnostic, that double
4349 constants fit in long double.
4351 2004-06-03 Kevin Ryde <user42@zip.com.au>
4353 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4354 malloc(0) and realloc(NULL,size).
4356 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4357 Bob Proulx.
4359 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4361 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4362 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4363 by Jim Meyering.
4365 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4367 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4368 can be rewritten using if-then-else. Suggested by Bruno Haible.
4370 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4372 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4373 Problem reported by Stepan Kasal.
4375 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4377 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4378 change). Patch reported by Ralf Wildenhues in
4379 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4381 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4382 function F exists if the compiler and linker let you compile an
4383 expression like (F != 0). Recent versions of GCC optimize away
4384 the reference to F in that case, since every function address must
4385 be nonzero, so the link succeeds even if F does not exist.
4386 Problem reported by Manu in
4387 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4389 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4390 "Unix". Many uses changed.
4391 (Limitations of Builtins): Explain better why the ! command isn't
4392 portable.
4394 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4396 * lib/autom4te.in (Automake-preselections): Preselect
4397 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4399 2004-05-19 Kevin Ryde <user42@zip.com.au>
4401 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4402 referencing AC_FUNC_STRERROR_R.
4404 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4405 note pessimistic assumption when cross compiling.
4407 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4409 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4410 (until 2004) invoked subcommands with sh -e, contra POSIX.
4411 Reported by Kevin Ryde.
4413 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4415 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4416 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4417 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4418 `test -f " /usr/bin/grep"', which _always_ failed.
4419 (AC_PROG_SED): Ditto bogus PATH fix.
4420 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4421 requires that grep correctly supports _multiple_ `-e' options, rather
4422 than stating only that grep should accept `-e'.
4424 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4426 Port to C99, which requires that 'exit' be declared.
4428 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4429 to ensure that stdlib.h is included.
4430 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4431 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4432 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4433 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4434 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4435 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4436 when using 'exit' in a test; C99 requires that 'exit' be declared.
4438 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4440 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4441 now prefers 'grep' implementations that accept -e.
4442 (Limitations of Usual Tools): Describe problems of traditional
4443 egrep and fgrep with long input lines, and of traditional grep
4444 with -e.
4445 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4446 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4447 All callers changed. Append /usr/xpg4/bin to the PATH, for
4448 Solaris.
4449 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4450 the user with complaints about multiple -e options.
4451 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4452 Define it with AC_PROG_GREP.
4453 * configure.ac (AC_PROG_GREP): Add.
4454 * lib/freeze.mk (GREP): New macro.
4456 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4458 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4459 a possible candidate only after all others fail, rather than
4460 consulting it first. This improves backward compatibility by
4461 better reflecting the way shell selection occurred in previous
4462 versions of Autoconf, and should help to avoid triggering latent
4463 problems in other packages, such as the one in Automake where zsh
4464 is not handled robustly:
4465 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4466 Although it is not Autoconf's responsibility to work around
4467 problems in Automake, it nevertheless makes sense to avoid
4468 introducing unnecessary incompatibilites.
4470 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4471 Gary V. Vaughan <gary@gnu.org>
4473 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4474 how deeply nested we are when a suitable tool is found, set the
4475 ac_path_TOOL_found flag.
4476 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4477 nested we are in this macro. Break out of all 3 nested loops if
4478 ac_path_TOOL_found is set.
4480 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4482 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4483 of the _AS_PATH_WALK loop too if GNU flavor is found.
4485 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4487 * doc/autoconf.texi (Limitations of Make): Update documentation
4488 for `$<'. New entry `Long lines', based on a report from Simon
4489 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4490 paragraph about DJGPP, based on a mail from Richard Dawe.
4492 2004-04-20 Paul Eggert <eggert@twinsun.com>
4494 * tests/c.at (C keywords): Don't assume that GCC supports
4495 "restrict" and "inline", as sufficiently-old GCC versions do not
4496 (also, GCC configured to be in pedantic C89 mode does not).
4497 Problem reported by Sumit Pandya in:
4498 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4500 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4501 consider -g to work if it generates warnings when plain compiles
4502 don't. Problem reported by Braden McDaniel in:
4503 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4505 * doc/autoconf.texi (Slashes): New section, to document a problem
4506 reported by Jim Meyering in:
4507 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4509 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4510 linker output files before linking, to work around IRIX 6 linker bug.
4511 Problem reported by Rainer Orth in:
4512 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
4514 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4516 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4517 best tool so far counter rely on the tool path variable name to
4518 avoid checks for one tool being affected by the results of running
4519 the length check on a previous tool.
4521 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4522 match expression argument, as different greps have different
4523 regular expression flavours.
4524 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4525 literals.
4526 (AC_PROG_EGREP): Pass 'EGREP$'.

4537 Types, Specific Compiler Characteristics, System Services,
4538 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4539 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4540 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4541 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

4554 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4555 now defines HAVE_DECL_TZNAME if it is declared, when
4556 HAVE_STRUCT_TM_TM_ZONE is not defined.
4557 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4558 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

4607 new macros.
4608 * NEWS: Document these changes.
4610 * doc/autoconf.texi: Avoid macros with unbraced arguments,

4616 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
4617 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than

4639 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4641 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'

4644 2004-02-18 Paul Eggert <eggert@twinsun.com>
4646 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4647 problem on QNX reported by Stephen Rasku in
4648 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4650 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on

4659 AC_SUBST provides no portable way to escape literal newlines.
4661 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4662 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4663 Darwin uses -lcrt2.o and there's little point to cataloging all
4664 the system variants. Partial fix reported by Andreas Waechter in:
4665 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
4666 for bug reported by Nelson H. F. Beebe in:

4689 Eric Sunshine <sunshine@sunshineco.com>

4696 (_AS_SHELL_FN_SPY): New macro.
4697 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New

4704 (AS_REQUIRE_SHELL_FN): Require shell functions when
4705 it is used.
4706 (_AS_LINENO_WORKS): Put around braces, we do not
4707 trigger the bash bug anymore.
4708 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
4709 use AS_INIT_WITH_SHELL_FN.
4710 * bin/autoconf.in, tests/wrapper.in: Regenerated.
4712 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

4718 (AU_DEFUN): Honor the third parameter, create autoupdate
4719 macros with AU_DEFINE.
4720 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
4721 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

4740 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
4741 2003 (except 1997) to the list of copyright years. This undoes
4742 the 2003-05-22 change, which removed the older years from the list.
4743 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4745 2004-01-27 Gary V. Vaughan <gary@gnu.org>

4757 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
4758 longest input length accepted by a command.
4759 (AC_PROG_SED): Use it.
4760 * doc/autoconf.texi (Particular Programs): Document the changes.

4785 sources.
4787 2004-01-26 Paul Eggert <eggert@twinsun.com>
4789 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4790 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4791 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4792 not <inttypes.h>. Problem reported by Tim Mooney in
4793 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4794 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4795 Likewise.
4797 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4798 otherwise "make check" fails because it forbids cmp (I guess
4799 because cmp treats files as binary on DOS-like systems).
4801 * tests/mktests.sh: Update copyright date to 2004, since some tests
4802 have changed in 2004.
4804 2004-01-23 Gary V. Vaughan <gary@gnu.org>

4807 non-truncating sed or gsed program in PATH.
4808 * tests/acprograms.at: Add it.

4810 * NEWS: Updated.
4812 2004-01-15 Paul Eggert <eggert@twinsun.com>
4814 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4815 -std1 disables some useful extensions on Tru64. Problem reported
4816 by N. Lichtmaier in
4817 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4819 2004-01-14 Paul Eggert <eggert@twinsun.com>
4821 * doc/autoconf.texi (Programming in M4sh): Document that
4822 AS_MKDIR_P succeeds if the destination is a symbolic link
4823 to an existing directory.
4824 (Limitations of Usual Tools): Note that mkdir -p might not
4825 succeed on symlinks to directories.
4827 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4829 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
4830 * bin/autoheader.in: Grammar fix in message.
4831 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
4832 Test for dir before calling mkdir -p. (trivial changes)
4834 2004-01-13 Eric Blake <ebb9@byu.net>
4836 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
4837 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
4839 2004-01-10 Jim Meyering <jim@meyering.net>
4841 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
4843 2004-01-09 Paul Eggert <eggert@twinsun.com>
4845 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4846 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4847 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4848 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4849 AC_COMPILE_IFELSE, since we now assume our caller invokes
4850 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4851 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4852 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4853 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4855 2004-01-07 Paul Eggert <eggert@twinsun.com>
4857 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4858 `"'...'"`, as it's confusing (and I suspect it may not work on
4859 some platforms). The code was incorrect anyway, as it assumed
4860 that \$ evaluated to itself in that context. Reported by
4861 Alexandre Duret-Lutz.
4863 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
4865 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
4866 and _LT_AC_TAGCONFIG.

4870 * doc/autoconf.texi (One Macro Call): Fix an incorrect
4871 example, and add more examples. Reported by Eric Sunshine.
4873 2004-01-05 Paul Eggert <eggert@twinsun.com>
4875 * doc/autoconf.texi (Limitations of Usual Tools):
4876 Remove warning against "rm -fr" introduced yesterday; it
4877 was a false alarm.
4879 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
4880 autoscan, autoupdate, ifnames): Don't use chmod -w.
4881 * lib/Makefile.am (autom4te.cfg): Likewise.
4882 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
4883 "chmod -w".

4886 Paolo Bonzini <bonzini@gnu.org>
4888 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
4889 by doing lineno substitution only on lines containing "$LINENO".
4891 2004-01-04 Paul Eggert <eggert@twinsun.com>
4893 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
4894 Use "rm -f" to remove conftest.sed, not plain "rm".
4895 Bug reported by David Relson in
4896 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
4898 * Makefile.am (autom4te-update):
4899 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
4900 * Makefile.maint (my-distcheck, do-po-update): Likewise.
4901 * doc/autoconf.texi (Guidelines): Likewise.

4910 * doc/autoconf.texi (Limitations of Usual Tools):
4911 Warn against "rm -fr".
4913 2004-01-03 Paul Eggert <eggert@twinsun.com>
4915 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
4916 -c -o might not work. From a suggestion by Kevin Ryde.
4917 (C Compiler, Generating Sources, Limitations
4918 of Usual Tools, Limitations of Make, Making testsuite Scripts):
4919 Don't put '-o' after non-options, as POSIX doesn't allow this.
4920 Mention that cc's name might be gcc or c89 or whatever.
4922 2004-01-04 Kevin Ryde <user42@zip.com.au>
4924 * doc/autoconf.texi: Add various further index entries.
4926 2003-12-29 Paul Eggert <eggert@twinsun.com>
4928 * bin/autoreconf.in (autoreconf_current_directory):
4929 Fix typo: mkdir without umask arg.
4931 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
4933 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
4934 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
4935 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
4936 explanation clearer.
4938 2003-12-24 Andreas Schwab <schwab@suse.de>
4940 * doc/autoconf.texi (Default Includes): Fix misspelling of
4941 AC_INCLUDES_DEFAULT.

4945 * configure.ac: Test if sh -n works.
4946 * configure: Regenerate.
4947 * tests/atlocal.in: Store the result here.
4948 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
4949 tools.at, looking in atlocal's ac_cv_sh_n_works instead
4950 of explicitly testing.
4951 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
4952 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
4953 * tests/tools.at (Syntax of the shell scripts): Simplify
4954 using AT_CHECK_SHELL_SYNTAX.
4955 (Syntax of the Perl scripts): Remove definition of
4956 AT_CHECK_PERL_SYNTAX.
4958 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
4960 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
4961 stderr to /dev/null.

4987 * config/announce-gen (&print_locations, &print_signatures)
4988 (&sizes): New.
4989 Use them.

4995 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

5038 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
5039 than $target since the latter is not usual, add guidelines on when to

5199 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
5200 cross test.
5202 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
5204 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
5205 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

5217 Problems reported by Eric Sunshine.
5219 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5221 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
5222 -mGLOB_options_string stuff for Intel ifc, which can cause

5246 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5247 cache variable instead of $G77 to decide whether to include -O2,
5248 since $G77 is specific to Fortran 77.

5252 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

5257 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
5258 arguments so that it can be used with syntax identical to
5259 AC_PROG_F77, and so that we can more easily decide to
5260 remove/deprecate the DIALECT optional argument in the future if it
5261 proves troublesome.
5262 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
5263 non-freeform-supporting compilers. Document freeform flags.
5265 2003-10-03 Akim Demaille <akim@epita.fr>
5267 * configure.ac: Look for emacs, not macs.

5270 2003-10-03 Akim Demaille <akim@epita.fr>

5277 2003-10-03 Akim Demaille <akim@epita.fr>
5279 * configure.ac: Quotation and formatting changes.

5301 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
5302 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.

5314 have been created when invoking the compiler.

5328 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5329 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5330 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5332 2003-09-26 Akim Demaille <akim@epita.fr>
5334 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5335 directory for AC_CONFIG_COMMANDS' first argument exists.
5336 This makes valid the invocation of _AC_SRCPATH that follows.
5337 Reported by Eric Sunshine.
5338 * doc/autoconf.texi (Configuration Commands): Adjust.
5340 2003-09-26 Akim Demaille <akim@epita.fr>
5342 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5343 Reported by Ralf Corsepius.
5345 2003-09-26 Akim Demaille <akim@epita.fr>
5347 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5348 arguments.

5359 2003-09-26 Akim Demaille <akim@epita.fr>
5361 The test suite are sometimes assigning timings incorrectly.
5362 Reported by Henk Krus.
5363 Diagnosed by Nicolas Joly.
5365 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5366 AT_help_all.
5367 Instead of making AT_help a sequence of assignments to grow
5368 $at_help_all, just make AT_help_all be the growing contents of
5369 $at_help_all, and make a single assignment in...
5370 (AT_INIT): here.
5371 (at_times_skip): Flip the meaning and rename as...
5372 (at_times_p): this.
5373 (AT_INIT): When summarizing the test that ran, remove
5374 $at_times_file after use, and check it is present before trying to
5375 use it.

5383 (ifnames): chmod -w.
5384 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5385 executables, not bin/ executables! Otherwise all the magic needed
5386 to find non installed files is turned off. This caused a failure
5387 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5388 as found in its environment (sent by tests/autoreconf): pointing
5389 to bin/autom4te that could not find its files.
5390 * tests/mktests.sh: Force the replacement of generated files, for
5391 the sake of "mv" program that are interactive when overwriting a
5392 -w file.

5403 Trivial change to support GCC's configuration procedure.
5404 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5405 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5406 about inconsistency if the preprocessor is set to give errors for
5407 any warning.

5426 2003-09-12 Akim Demaille <akim@epita.fr>
5428 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
5429 not asm/types.h.
5431 2003-09-11 Akim Demaille <akim@epita.fr>
5433 * doc/autoconf.texi (Header Portability): linux/random.h.
5434 From Peter Hendrickson.
5436 2003-09-10 Akim Demaille <akim@epita.fr>
5438 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
5439 willing to edit the output files.
5441 2003-09-10 Akim Demaille <akim@epita.fr>
5443 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
5444 and AC_FC_FREEFORM.
5445 * tests/mktests.sh: Skip AC_FC_SRCEXT.
5446 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

5461 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
5462 Improve the accuracy of the wording about obsolescence.
5463 From a suggestion by Ian Lance Taylor in
5464 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
5466 2003-09-05 Paul Eggert <eggert@twinsun.com>
5468 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
5469 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
5471 2003-09-04 Akim Demaille <akim@epita.fr>
5473 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
5474 AC_FUNC_WAIT3.
5476 2003-09-04 Akim Demaille <akim@epita.fr>
5478 * bin/autom4te.in: Use &fatal where more appropriate than &error.
5479 (freeze): When exiting, use $exit_code.
5480 * lib/autoconf/fortran.m4: Comment changes.
5482 2003-09-04 Akim Demaille <akim@epita.fr>
5484 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
5486 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
5488 Add support for newer Fortran dialects. The F77 interface is
5489 unchanged, and continues to support Fortran 77. New FC macros
5490 correspond to all the old F77 macros, with output variables FC,
5491 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5492 available dialect, but older dialects can be specified. There are
5493 new macros AC_FC_SRCEXT to set the source extension, and
5494 AC_FC_FREEFORM to accept free-form source files.
5496 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
5497 New macros.
5498 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
5499 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
5500 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
5501 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

5509 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
5510 AC_FC_SRCEXT, AC_FC_FREEFORM):
5511 New macros.
5512 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
5513 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
5514 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
5515 Rewrite in terms of the above.
5516 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
5517 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
5518 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
5519 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
5521 2003-09-02 Paul Eggert <eggert@twinsun.com>
5523 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
5524 Document problems with timestamp resolution that 'make', 'cp -p', and
5525 'touch -r' have.
5527 2003-08-27 Akim Demaille <akim@epita.fr>
5529 * tests/m4sugar.at (cross_warning): Make sure to enable the
5530 output, so that we can track spurious m4sugar output.
5531 * tests/local.at: Require 2.57.
5532 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5533 are defaulted by AT_CHECK anyway.
5534 Use AT_CHECK_AUTOM4TE.
5535 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5536 missing dnl.
5538 2003-08-27 Akim Demaille <akim@epita.fr>
5540 * bin/autoheader.in: Issue the "Using auxiliary..." message only
5541 when -Wobsolete is set.
5542 Set it on by default.
5543 Suggested by Klee Dienes.
5545 2003-08-27 Akim Demaille <akim@epita.fr>
5547 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
5548 documentation.
5549 From Guido Draheim.
5551 2003-08-26 Akim Demaille <akim@epita.fr>
5553 * doc/autoconf.texi (Output): Make clear that one can run code
5554 after AC_OUTPUT.
5556 2003-08-25 Akim Demaille <akim@epita.fr>
5558 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
5559 CVS Bison.
5561 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>

5584 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
5585 * configure.ac: Require Automake 1.7.6.
5587 2003-08-22 Akim Demaille <akim@epita.fr>
5589 Output stack traces in warnings.
5591 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
5592 Replace the former...
5593 (m4_warn): Pass the call stack to _m4_warn.
5594 * bin/autom4te.in: Adjust to output the call stack.
5595 * tests/m4sugar.at (m4@&t@_warn): Adjust.
5597 2003-08-22 Akim Demaille <akim@epita.fr>
5599 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
5600 * bin/autom4te.in: Adjust.
5602 2003-08-21 Akim Demaille <akim@epita.fr>
5604 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
5605 (&verbose): Remove.
5606 (&getopt): Adjust the note and verb channels, depending upon
5607 --verbose.
5608 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
5609 * bin/autoupdate.in: Adjust.
5610 Use &verb, not &verbose.
5612 2003-08-21 Akim Demaille <akim@epita.fr>
5614 * bin/autoheader.in (&parse_args): Use &parse_warnings and
5615 &parse_WARNINGS.
5616 ($help): Use Autom4te::ChannelDefs::usage.
5617 * bin/autoscan.in: Use Autom4te::ChannelDefs.
5618 * lib/Autom4te/General.pm: Don't export error: you don't own it.
5620 2003-08-21 Akim Demaille <akim@epita.fr>
5622 First stab at preserving warnings between calls to autom4te,
5623 including when the cache is used.
5625 There are still several issues: (i) there are too many runs of m4
5626 (one for include, one for warnings, and some more), (ii) warnings
5627 spreading on several lines are not handled gracefully, (iii) the
5628 code meant to have the call stack display for errors does not work
5629 (its handling should move from m4 to autom4te).
5631 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5632 Use them.
5633 (@preselect): Add m4_warn.
5634 ($exit_status): Remove, use $exit_code.
5635 ($help): Use Autom4te::ChannelDefs::usage.
5636 (&handle_m4): No longer define the m4_warnings.
5637 At each run, extract and report the warnings.
5638 Always cache the result, including if the exit status is on
5639 failure, since if nothing changes, we should result in the same
5640 failure, hence we can use the cache.
5641 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5642 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5643 Remove.
5644 (m4_warn): Redefine as a do-nothing: it is its invocation that
5645 matters, as warnings are now reported via traces.
5646 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5647 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5648 the latter reveals calls to the former.
5650 Adjust the tests.
5652 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5654 2003-08-21 Akim Demaille <akim@epita.fr>
5656 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
5657 Use them.
5659 2003-08-21 Akim Demaille <akim@epita.fr>
5661 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
5662 forward order.
5663 * lib/Autom4te/ChannelDefs.pm: Doc typos.
5664 (&parse_warnings): Accept a list of warning requests.
5665 (&usage): Return a string, not a side effect.
5666 (cross): New warning category.
5668 2003-08-21 Akim Demaille <akim@epita.fr>
5670 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
5671 (&require_configure_ac): Accept an optional directory argument.
5672 ($configure_ac): Remove.
5673 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
5674 (&catfile): Remove.
5675 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
5676 * bin/autoscan.in: Adjust.
5678 2003-08-20 Akim Demaille <akim@epita.fr>
5680 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5681 Reported by Alexandre Duret-Lutz.
5683 2003-08-20 Akim Demaille <akim@epita.fr>
5685 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5686 * bin/autom4te: Adjust.
5687 In particular, be Autoconf tools are really silent when properly
5688 working, bind the verbosity of the 'note' channel to $verbose.
5689 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5690 (&xsystem, &contents): Remove, since they are exported by...
5691 * lib/Autom4te/FileUtils.pm: this.
5692 More perldoc.
5693 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
5694 * lib/Autom4te/FileUtils.pm: here.
5696 2003-08-20 Akim Demaille <akim@epita.fr>
5698 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
5699 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
5700 from CVS Automake.
5702 2003-08-20 Akim Demaille <akim@epita.fr>
5704 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
5705 (autom4te-update): New.
5706 * Makefile.cfg (update): Bind autom4te-update.
5708 2003-08-19 Derek Price <derek@ximbiot.com>
5710 * lib/autotest/general.m4: Comment various HELP_* diversions.
5711 (PARSE_ARGS_BEGIN): New section for option parsing related
5712 initialization.

5725 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
5726 and m4_sinclude.
5728 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
5730 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...

5732 * doc/autoconf.texi (autom4te Invocation): Mention
5733 Autoconf-without-aclocal-m4.

5738 RUN-IF-PASS optional arguments.
5740 2003-08-18 Derek Price <derek@ximbiot.com>

5749 2003-08-14 Derek Price <derek@ximbiot.com>
5751 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
5752 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
5753 shorter column three. Add DESCRIPTION to log file content.
5755 2003-08-13 Derek Price <derek@ximbiot.com>
5757 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
5758 output.
5760 2003-08-12 Derek Price <derek@ximbiot.com>
5762 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
5763 (AT_CHECK_NOESCAPE): Move core functionality to...
5764 (_AT_CHECK): ...this new macro.
5766 2003-08-07 Derek Price <derek@ximbiot.com>
5768 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
5769 (AT_CHECK_NOESCAPE): ...to this new macro.
5771 2003-07-31 Paul Eggert <eggert@twinsun.com>
5773 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
5774 in Bash 2.01. Problem reported by Brian Gough in
5775 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
5777 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
5779 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
5780 -lcrt1.o, for OS X. (trivial change)
5782 2003-07-07 Paul Eggert <eggert@twinsun.com>
5784 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
5785 inside '#ifndef __cplusplus'. Problem reported by
5786 Bob Friesenhahn.
5788 2003-07-06 Bill Clarke <llib@computer.org>
5790 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
5791 'long', not 'int', for benefit of Sun's recent C++ compilers
5792 (trivial change). See:
5793 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
5794 (This really should be 'intptr_t', not 'long', but that would
5795 take more work.)
5797 2003-06-25 Akim Demaille <akim@epita.fr>
5799 * lib/Makefile.am (autom4te.cfg): Make it read only.
5800 Depend on Makefile since it contains substitutions.
5801 From Paolo Bonzini.

5803 This change was made on autom4te.cfg which is generated.
5804 Reported by Raja R. Harinath.
5806 2003-06-25 Akim Demaille <akim@epita.fr>
5808 * doc/autoconf.texi (Header Portability): sys/mount.h.
5809 From Gareth McCaughan.
5811 2003-06-23 Akim Demaille <akim@epita.fr>
5813 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5814 not all of them. This fixes 1. the fact that when testing
5815 Autoconf there are many many config.log, 2. the incorrect use of
5816 top_srcdir to find config.log.
5817 Don't mix the detailed output of failed test with the summary of
5818 failures. Rather, append detailed log afterwards.
5820 2003-06-23 Akim Demaille <akim@epita.fr>
5822 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5823 always run: output config.log on $at_group_log.
5825 2003-06-23 Akim Demaille <akim@epita.fr>
5827 * tests/torture.at (#define header templates): Don't use quotes in
5828 C++ comments as it puzzles Emacs' sh font-lock-mode.
5830 2003-06-23 Akim Demaille <akim@epita.fr>
5832 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
5833 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
5834 * tests/atspecific.m4: Rename as...

5841 2003-06-21 Kevin Ryde <user42@zip.com.au>
5843 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
5844 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
5845 ensuring we add -std1 for full-ANSI.
5847 * doc/autoconf.texi (hdrindex): New macro.
5848 Add index entries for portability of various standard header files.
5850 2003-06-20 Akim Demaille <akim@epita.fr>
5852 * configure.ac: Bump to 2.57b.
5854 2003-06-20 Akim Demaille <akim@epita.fr>
5856 Version 2.57a.
5858 2003-06-20 Akim Demaille <akim@epita.fr>
5860 * bin/autom4te.in: Don't rely on $HOME being defined.
5861 Reported by Marc Espie as PR/233.
5863 2003-06-20 Akim Demaille <akim@epita.fr>
5865 * lib/autotest/general.m4: Use at_times_file only if used.
5866 From Nicolas Joly.
5868 2003-06-20 Akim Demaille <akim@epita.fr>
5870 * config/config.guess, config/config.sub, config/elisp-comp,
5871 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
5872 Update from masters.
5874 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
5876 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
5877 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
5878 (TEST_SCRIPT): New diversion.
5879 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
5880 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
5881 (AT_INIT): Support for expected failures.
5883 2003-06-02 Akim Demaille <akim@epita.fr>
5885 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
5886 changes.
5887 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
5888 Autoconf nor Automake.
5889 (&contents): New, from Automake.
5890 PODify.
5892 2003-05-28 Paul Eggert <eggert@twinsun.com>
5894 * NEWS, doc/autoconf.texi (Particular Functions),
5895 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
5896 is the inverse of localtime.
5898 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
5900 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
5901 (handle_exec_errors): New function. Work around $! being
5902 altered by WEXITSTATUS.
5903 (xqx, xsystem): Use handle_exec_errors.
5905 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5907 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5908 Do not call `_exit()', simply modify `$?'.
5909 (xsystem): Reset $! before running system, and check it afterward.
5910 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
5911 63 for version mismatches.
5913 2003-05-23 Akim Demaille <akim@epita.fr>
5915 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
5916 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
5917 the middle of a line).
5918 * lib/m4sugar/m4sugar.m4: Likewise.
5919 Remove useless spaces in comments.
5921 2003-05-23 Akim Demaille <akim@epita.fr>
5923 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
5924 exit 63, so that we (or Automake's "missing") can tell the
5925 difference with a plain failure.
5926 * doc/autoconf.texi (Notices): Adjust.
5928 2003-05-23 Akim Demaille <akim@epita.fr>
5930 * Makefile.am, bin/Makefile.am, config/Makefile.am,
5931 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
5932 White spaces cleanup.
5934 2003-05-22 Jim Meyering <jim@meyering.net>
5935 Paul Eggert <eggert@twinsun.com>
5937 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5938 Remove `#include <stdlib.h>' from the list; we should never
5939 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5940 resulting namespace pollution would cause other tests to fail.
5941 Configure scripts run with some older versions of g++ and HP's
5942 aCC would fail due to such an #include. Problems reported by
5943 Matthew Mueller in <http://bugs.debian.org/120704> and by
5944 Keith Bostic in
5945 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5946 In the test, use the test declaration before including <stdlib.h>,
5947 as that's closer to how it'll be used.
5949 2003-05-23 Akim Demaille <akim@epita.fr>
5951 * doc/autoconf.texi (Header Portability): ucred.h.
5952 From Ian Redfern.
5954 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5956 Overhaul Autotest's logging: generate separate log files
5957 in testsuite.dir/NNN/testsuite.log, and append them to
5958 testsuite.log instead of re-running the test verbosely.
5960 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5961 file descriptor, write 0 to at_status_file instead of setting
5962 at_status=0, initialize some new variables (at_status_file,
5963 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
5964 to rerun the tests, instead append the at_group_log to the
5965 at_suite_log when a test fails.
5966 (AT_SETUP): pipe the test case's output into at_tee_pipe,
5967 with the AS_MESSAGE_LOG_FD redirected to stdout.
5968 (AT_CLEANUP): save the output status in $at_status_file
5969 and restore it, redirect the AS_MESSAGE_LOG_FD back to
5970 its original place.
5971 (AT_CHECK): since tests are run with a redirected stdout,
5972 and used to be re-run in verbose mode, turn some $at_verbose
5973 into echo, and don't redirect the output of testing stdout
5974 and stderr.
5976 * lib/autotest/autoconf.texi (testsuite Scripts): Update
5977 the name of the debugging directory and information about
5978 its contents.
5980 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5982 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd

6095 and truncate.
6097 2003-05-06 Akim Demaille <akim@epita.fr>
6099 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6100 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6101 by aclocal.m4 is changed it might require the importing of another
6102 m4 extension file, i.e., aclocal must be run.
6104 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6105 (&parse_args): Use --force with aclocal if required and supported.

6113 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6114 argument instead of a file name, so that the request file remains
6115 open during the whole autom4te run.
6116 ($icache_file): New.
6117 (&freeze): Lock the $icache_file.
6119 2003-04-29 Derek Price <derek@ximbiot.com>
6121 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6122 seperator with m4_append_uniq(). It doesn't work.
6123 (AT_CLEANUP): Add `;' to end of at_help_all.
6124 (AT_INIT): Allow --keywords to be specified more than once. When
6125 grepping $at_help_all for keywords, use the field and keyword
6126 seperators to ensure a complete keyword match. Alter at_prev handling
6127 to support the new --keywords behavior.
6129 2003-04-27 Karl Berry <karl@freefriends.org>
6131 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6132 align better with others. I also made some of the individual
6133 entries on one line, for brevity and to make it easier for me to
6134 sort my dir-example file in the Texinfo distribution :).
6136 2003-04-12 Jim Meyering <jim@meyering.net>

6203 2003-03-28 Akim Demaille <akim@epita.fr>
6205 * tests/torture.at (Configuring subdirectories): Require aclocal
6206 1.4, otherwise the test fails, as it does support configure.ac.

6302 When constructing paths with IFS=:, quote the path. If we're

6326 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
6327 format starting with "-".
6329 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6331 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
6332 is not portable inside Makefile.
6334 2003-02-20 Akim Demaille <akim@epita.fr>
6336 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
6337 compiler says yeah, but preproc says nope, compiler is right.
6338 Conversely, prompt the reader to send a bug report to the
6339 maintainers of the package, not of Autoconf.
6341 2003-02-20 Klee Dienes <kdienes@apple.com>

6354 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6355 innocuous variant befor including <limits.h> or <assert.h>. This
6356 works around a bug reported by Albert Chin: HP-UX 11i
6357 (and earlier versions) have a <limits.h> that declares
6358 gettimeofday and many other functions.
6360 2002-12-03 Paul Eggert <eggert@twinsun.com>
6362 Version 2.57.
6364 * NEWS, configure.ac: Update version.

6368 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6369 nontrivially in main's body, so that f's external declaration is
6370 not optimized away in AIX. This should fix the bug reported by
6371 Martin Frydl in
6372 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6374 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6375 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6376 defined, to support freestanding compilers. This should fix the
6377 bug reported by Momchil Velkov in
6378 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6380 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6381 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

6386 * Makefile.maint (www-gnu): New macro.
6387 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
6388 the location has moved.
6390 2002-12-02 Martin Frydl <martin@systinet.com>
6392 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6393 \(.*\) match is too long and there is something more to be checked.
6394 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

6412 Update from masters.
6414 2002-11-14 Akim Demaille <akim@epita.fr>
6416 * Makefile.maint: Sync with Bison, i.e.:
6417 (po-check): Scan .l and .y files instead of the
6418 .c and the .h files that they generate. This fixes the bug
6419 reported by Tim Van Holder in:
6420 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6421 Look for N_ as well as for _. Try to avoid matching #define for
6422 N_ and _.
6423 From Paul Eggert.
6425 2002-11-14 Akim Demaille <akim@epita.fr>

6444 option to configure on --recheck.

6449 config.status -q option.
6451 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

6476 Reported by Ezra Peisach.
6478 2002-11-05 Akim Demaille <akim@epita.fr>
6480 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6481 Remove.
6482 We _have_ to stop using the old compatibility scheme that tried to
6483 avoid useless backslashes because Libtool 1.4.3 contains a
6484 AC_DEFINE([error_t], [int],
6485 [Define to a type to use for \`error_t' if it is not
6486 otherwise available.])
6487 We _have_ to quote the single quote and backslashes with \. The
6488 old compatibility scheme saw that ` was backslashed, and therefore
6489 did not quote the single quote. Hence before this patch, Autoconf
6490 was not compatible with Libtool.
6492 2002-11-04 Paul Eggert <eggert@twinsun.com>

6564 Problem reported by Bruno Haible.
6566 2002-10-29 Akim Demaille <akim@epita.fr>
6568 * doc/autoconf.texi (Header Templates): Put also in words what the

6880 longer required can still cause errors.
6881 Reported by Alexandre Duret-Lutz.
6883 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

6923 * lib/autotest/general.m4 (AT_INIT): Include the failed test
6924 numbers in the Subject suggestion.
6926 2002-10-11 Akim Demaille <akim@epita.fr>
6928 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
6929 Suggest using AC_CHECK_DECLS instead.
6931 2002-10-11 Akim Demaille <akim@epita.fr>
6933 * tests/torture.at (AC_ARG_VAR): Have configure report the value
6934 of `precious'.
6936 2002-10-11 Akim Demaille <akim@epita.fr>
6938 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
6939 file name to enable parallel executions.
6940 From Sam Varshavchik.
6942 2002-10-08 Akim Demaille <akim@epita.fr>
6944 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
6945 aclocal invocation, as Gettext macros might not be visible to
6946 aclocal.
6947 Instead of blindly running autopoint, scan configure.ac (not the
6948 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
6949 Reported by Paul D. Smith.
6951 2002-10-08 Paul Eggert <eggert@twinsun.com>
6953 Work around problems found when POSIXLY_CORRECT=1 is set.
6954 None of this seems to have anything to do with POSIX, really,
6955 but it's how Perl getopt works.
6956 * bin/autom4te.in (parse_args): Configure GetOpt with
6957 "permute", too.
6958 * doc/autoconf.texi (Invoking autom4te):
6959 --warning -> --warnings.
6960 * lib/autom4te.in: --warning -> --warnings.
6962 2002-09-28 Akim Demaille <akim@epita.fr>
6964 * doc/autoconf.texi (autom4te.cache): New section.
6966 2002-09-28 Akim Demaille <akim@epita.fr>
6968 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
6969 (Automake-preselections): Update.
6970 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
6972 2002-09-28 Akim Demaille <akim@epita.fr>
6974 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
6975 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
6976 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
6977 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
6979 2002-09-28 Akim Demaille <akim@epita.fr>
6981 * tests/torture.at (Configuring subdirectories): Be robust to
6982 users who use config.site to require for a cache: in this case,
6983 the two last configure runs, using two different sets of
6984 arguments, trigger a legitimate error.
6986 2002-09-28 Akim Demaille <akim@epita.fr>
6988 * tests/m4sh.at (Functions Support, Functions and return Support):
6989 New.
6991 2002-09-28 Akim Demaille <akim@epita.fr>
6993 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
6994 autoheader are Perl programs.
6995 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
6996 (autom4te): Specify that the sources are in the $srcdir.
6997 * doc/autoconf.texi (Installation Directory Variables): Adjust.
6999 2002-09-28 Akim Demaille <akim@epita.fr>
7001 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
7002 (tm_zone): Move their rules to...
7003 * lib/autoconf/types.m4: here, using AN_ macros.
7004 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
7005 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7006 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
7007 * lib/autoconf/programs.m4: here.
7008 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
7009 (ETAGS_FOR_AUTOCONF): New.
7010 Use it.
7012 2002-09-28 Akim Demaille <akim@epita.fr>
7014 * lib/autoconf/autoscan.m4: New file.
7015 * lib/autoconf/autoconf.m4: Include it.
7016 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
7017 that were listed in the original autoscan.list.
7018 * lib/autoconf/headers.m4: Similarly with headers.
7019 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
7020 (.m4.m4f): Don't pass --prepend-include, since that's done by
7021 tests/autom4te itself.
7022 * lib/autoscan/Makefile.am: Include freeze.mk.
7023 (autoscan.list): New target --this file is no longer a source.
7024 (autoscan.pre): New file.
7026 2002-09-28 Akim Demaille <akim@epita.fr>
7028 * bin/autoscan.in (@kinds): Make them singular.
7029 Adjust all uses.
7030 (&init_tables): When --debug, report the list of rules to ease
7031 tracking changes in autoscan.list.
7032 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7034 2002-09-28 Akim Demaille <akim@epita.fr>
7036 * lib/autoscan/functions, lib/autoscan/headers,
7037 * lib/autoscan/identifiers, lib/autoscan/makevars,
7038 * lib/autoscan/programs: Merge into...
7039 * lib/autoscan/autoscan.list: this.
7040 * bin/autoscan.in (&init_tables): Adjust.
7042 2002-09-28 Akim Demaille <akim@epita.fr>
7044 * lib/autoscan/functions, lib/autoscan/headers,
7045 * lib/autoscan/identifiers, lib/autoscan/makevars,
7046 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
7047 `functions' line is now prefixed with `function:'.
7048 * bin/autoscan.in (&init_tables): Adjust.
7050 2002-09-28 Akim Demaille <akim@epita.fr>
7052 From now on, autoscan files must always map a macro name to a
7053 word: there is no `default' macro for autoscan.
7055 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7056 all.
7057 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7058 explicit.
7060 2002-09-28 Akim Demaille <akim@epita.fr>
7062 * bin/autoscan.in (%c_keywords): Remove.
7063 (&used): Keep only track of the words we might be interested in.
7064 (&output_kind): It is no longer needed to look for non active
7065 checks.
7067 2002-09-27 Akim Demaille <akim@epita.fr>
7069 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
7070 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
7071 * lib/autoscan/functions: Adjust.
7072 * doc/autoconf.texi (Particular Functions): Adjust.
7074 2002-09-27 Akim Demaille <akim@epita.fr>
7076 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
7077 from /tmp.
7078 Thanks to Bill Moseley and Paul Eggert.
7079 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
7080 the tmpdir must be created.
7081 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
7082 dir be in the build tree, instead of $TMPDIR.
7084 2002-09-27 Akim Demaille <akim@epita.fr>
7086 * bin/autoscan.in: Improve the comments.
7087 (&parse_args): Drop obsolete undocumented options.
7088 (&output_kind): Output warnings.
7089 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
7090 (getwd): Trigger a warning.
7092 2002-09-26 Akim Demaille <akim@epita.fr>
7094 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
7095 Reported by Ralf Corsepius.
7096 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7098 2002-09-26 Akim Demaille <akim@epita.fr>
7100 Single suffix rules and seperated dependencies are not portable.
7102 * doc/autoconf.texi (Installation Directory Variables): Update.
7103 (Limitations of Make): Some about `Single Suffix Rules and
7104 Separated Dependencies'.
7105 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7106 (ifnames, autoscan, autom4te): Un-factor into several rules.
7108 2002-09-25 Paul Eggert <eggert@twinsun.com>
7110 * BUGS (Interoperability bugs): New section. Mention libtool
7111 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
7113 2002-09-24 Paul Eggert <eggert@twinsun.com>
7115 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
7116 make handles suffix-rules differently from GNU make.
7118 * bin/Makefile.am (SUFFIXES, .in): Remove.
7119 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
7120 Move the body of the old .in rule here.
7122 2002-09-16 Akim Demaille <akim@epita.fr>
7124 i960 compilers create `b.out' files by default.
7125 Reported by Ralf Corsepius.
7127 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
7128 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
7130 2002-09-13 Paul Eggert <eggert@twinsun.com>
7132 * doc/autoconf.texi (Particular Headers): Remove obsolete
7133 reference to `struct timezone' in the description of
7134 AC_HEADER_TIME.
7136 2002-09-13 Akim Demaille <akim@epita.fr>
7138 Version 2.54.
7140 * config/config.sub, config/config.guess: Update.
7141 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
7142 * Makefile.am: Adjust.
7144 2002-09-13 Akim Demaille <akim@epita.fr>
7146 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
7147 reading config.log when the compiler is rejected.
7148 Suggested by Guido Draheim.
7150 2002-09-13 Akim Demaille <akim@epita.fr>
7152 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
7153 (chdir_init) might hang when stat'ing mounted directories.
7154 Reported by Vance Shipley.
7156 2002-09-12 Akim Demaille <akim@epita.fr>
7158 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7159 the lists.
7161 2002-09-12 Akim Demaille <akim@epita.fr>
7163 * doc/autoconf.texi (Defining Symbols): Present two different
7164 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
7165 difference between 1 argument calls, and 2-3 argument calls.
7167 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
7169 * doc/autoconf.texi: Review grammar and punctuation.
7171 2002-09-11 Paul Eggert <eggert@twinsun.com>
7173 * doc/autoconf.texi: Fix minor formatting, spelling, and
7174 grammatical typos.
7175 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7176 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7177 is obsolescent.
7179 2002-09-11 Akim Demaille <akim@epita.fr>
7181 * doc/autoconf.texi (Questions): Rename as...
7182 (FAQ): this.
7183 (Defining Directories): New.
7185 2002-09-09 Akim Demaille <akim@epita.fr>
7187 * doc/autoconf.texi (Making testsuite Scripts): Update.
7188 Suggested by Nishio Futoshi.
7190 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
7192 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
7193 plain `@' is wanted.
7195 2002-09-09 Akim Demaille <akim@epita.fr>
7197 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7198 `duplicates', since the algorithm was too naive and could keep
7199 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7200 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7201 Reported by Ralf Corsepius.
7202 * tests/torture.at (Configuring subdirectories): Exercise these
7203 cases.
7205 2002-09-09 Akim Demaille <akim@epita.fr>
7207 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
7208 looking for a replacement file.
7209 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7210 directory is relative.
7211 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7212 directory definition.
7213 Reported by Andreas Schwab and Jim Meyering.
7215 2002-09-06 Akim Demaille <akim@epita.fr>
7217 * doc/autoconf.texi (Setting Output Variables): Clarify what
7218 precious variables are.
7219 Suggested by Pontus Skoeld.
7221 2002-09-05 Akim Demaille <akim@epita.fr>
7223 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7224 (ifnames, autoscan, autom4te): Since we don't only depend on
7225 configure.ac variables (such as VERSION etc.), but also on prefix
7226 and so forth, depend on Makefile, not configure.ac.
7227 Reported by Alexandre Duret-Lutz.
7228 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7230 2002-09-05 Kevin Ryde <user42@zip.com.au>
7232 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7233 doesn't seem to be confined to ia64, just say "some versions".
7235 2002-09-04 Akim Demaille <akim@epita.fr>
7237 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
7238 Automake 1.6c.
7239 * Makefile.am (maintainer-clean-local): Remove.
7240 (MAINTAINERCLEANFILES): Remove COPYING.
7242 2002-09-03 Paul Eggert <eggert@twinsun.com>
7244 * doc/autoconf.texi (Configuration Commands): Remove obsolete
7245 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
7246 Brinkmann.
7248 2002-09-03 Akim Demaille <akim@epita.fr>
7250 * configure.ac: Bump to 2.53d.
7251 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
7252 as of today, on Automake's team suggestion.
7254 2002-09-03 Akim Demaille <akim@epita.fr>
7256 Version 2.53c.
7258 2002-09-02 Akim Demaille <akim@epita.fr>
7260 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7261 SITE_MACRO_DIR.
7262 * configure.ac: Disable SITE_MACRO_DIR.
7264 2002-09-02 Jim Meyering <meyering@lucent.com>
7266 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7267 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7268 Also, tweak grammar: s/make sure to/be sure to/.
7270 2002-09-02 Paul Eggert <eggert@twinsun.com>
7272 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7273 directory names are generally preferable to physical names.
7275 2002-09-02 Akim Demaille <akim@epita.fr>
7277 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7278 Reported by Raja R. Harinath.
7279 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7280 * bin/autoupdate.in: Use error instead of die.
7282 2002-09-01 Paul Eggert <eggert@twinsun.com>
7284 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7285 ordinary shell concatenation rather than echo+tr+sed command that
7286 runs afoul of a long-line-related sed bug in Solaris 8.
7288 * bin/autoheader.in (parse_args): --warning -> --warnings.
7290 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7291 stdout, as traditional "ls" does.
7292 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7293 _AC_COMPILER_EXEEXT_O): Likewise.
7294 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7296 * bin/autoconf.as: Add --prepend-include option. This patch was
7297 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7298 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7300 * bin/autoconf.in, configure: Regenerate.
7302 * doc/autoconf.texi (Special Shell Variables): Mention
7303 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7305 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7306 MAILPATH and set PS1, PS2, PS4 to default values, to work
7307 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7308 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7309 the Autoconf documentation specifies; fall back to "unset" only if
7310 this fails. Use a shell for-loop for this rather than an m4 loop,
7311 to shorten the output script.
7313 2002-08-30 Paul Eggert <eggert@twinsun.com>
7315 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7316 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7317 for the CDPATH problem. Document PWD.
7318 (Limitations of Builtins): Document the problem that "cd $foo" and
7319 "ls $foo" may refer to different directories in shells conforming
7320 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7321 example, since the old example is now out of date.
7323 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7324 FOO" and "ls FOO" talk about different directories; this catches
7325 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7326 spaghetti.
7328 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7329 of rolling our own unset.
7330 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7331 in practice we needn't worry about CDPATH if unset doesn't work.
7333 * Makefile.in, aclocal.m4, bin/Makefile.in,
7334 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7335 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7336 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7337 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7338 tests/Makefile.in: Regenerate with Automake 1.6.3.
7340 * config/config.guess, config/config.sub, config/mkinstalldirs:
7341 Update.
7343 * configure: Regenerate with self.
7345 2002-08-30 Kevin Ryde <user42@zip.com.au>
7347 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7348 default output.
7350 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7352 * bin/autom4te.in (Request::load): Correctly test for "do" read
7353 failure.
7355 2002-08-29 Akim Demaille <akim@epita.fr>
7357 * lib/Autom4te/General.pm (&xqx): New.
7358 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7359 hand, which is not portable.
7360 (&error): New.
7361 * bin/autom4te.in: Use them.
7362 Use &error instead of die.
7363 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7364 Adjust.
7366 2002-08-17 Paul Eggert <eggert@twinsun.com>
7368 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7369 default list of compilers to try, since it was long ago superseded
7370 by the ksh fc builtin. Suggested by Steven G. Johnson.
7372 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7374 * doc/autoconf.texi (Invoking autom4te): End the option table,
7375 fixing a bug introduced by the previous patch.
7376 (Limitations of Make): Add a 'target lookup' subentry in the
7377 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7379 2002-07-29 Mark D. Roth <roth@feep.net>
7381 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7382 options and use $AUTOM4TE_PATH.
7383 * doc/autoconf.texi: Remove documentation of autom4te
7384 --include-envvar and --site-macro-subdir options and document
7385 use of $AUTOM4TE_PATH.
7386 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7387 arguments from each language section.
7389 2002-07-29 Paul Eggert <eggert@twinsun.com>
7391 * doc/install.texi: Include copyright symbol in copyright notice.
7393 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7394 Replace with:
7395 (AM_MAKEINFOFLAGS): New macro.
7396 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7397 * Makefile.am (INSTALL): Use the new macros.
7398 Use -o rather than --output, since "missing" does not grok --output.
7400 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7402 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7403 comments do not always work. Never trust the exit status of
7404 `make -k'.
7406 2002-07-24 Kevin Ryde <user42@zip.com.au>
7408 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7409 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7411 2002-07-23 Paul Eggert <eggert@twinsun.com>
7413 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7414 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7415 apparently treats PATH="nonexistent" as if it contained ".".
7416 Bug reported by Stefan `Sec' Zehl.

7542 2002-06-27 Paul Eggert <eggert@twinsun.com>
7544 * config/install-sh: Quote $src. Prefer || to test's -o option,
7545 as per "Limitations of Builtins".

7577 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>

7607 2002-06-07 Akim Demaille <akim@epita.fr>
7609 * bin/autom4te.in (warn_forbidden): When rejecting a token,

7618 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

7672 version of Autoconf that is discussed.
7674 2002-05-22 Paul Eggert <eggert@twinsun.com>
7676 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7677 from the default list of compilers to try. Suggested by
7678 Kate Hedstrom.
7679 * NEWS: Document the above.
7680 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7682 2002-05-17 Paul Eggert <eggert@twinsun.com>
7684 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7685 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7686 This improves on an earlier suggestion by H. Peter Anvin.
7688 2002-05-16 Paul Eggert <eggert@twinsun.com>
7690 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7691 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7692 Both macros now accept an optional source-dir arg.
7693 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7695 * NEWS: Document this.
7696 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7698 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7699 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7700 not for GNU extensions; this undoes part of the 2000-11-03 change,
7701 reverting to 2.13-compatible behavior.
7702 Add new optional argument DIR.
7703 (AC_FUNC_FNMATCH_GNU): New macro.
7705 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7707 2002-05-08 Paul Eggert <eggert@twinsun.com>
7709 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7710 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7711 and it causes a 'test' syntax error if it fails.
7712 Bug reported by Stephen Gildea.
7714 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7715 If prototypes are supported, use them to check this at compile-time,
7716 instead of trying to check it at run-time. If we must do a run-time
7717 check, assume that setvbuf is standard when cross-compiling, as
7718 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7719 Bug reported by Paul D. Smith.
7721 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7722 argument specifying location of getloadavg.c. This removes a
7723 FIXME. This idea was taken from Jim Meyering's implementation in
7724 textutils.
7725 * doc/autoconf.texi (Particular Functions): Document this.
7726 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7727 that's what the code does; this fixes a bug reported by
7728 Paul D. Smith.
7730 2002-05-03 Akim Demaille <akim@epita.fr>
7732 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7733 autopoint instead of gettextize.
7734 ($uses_alocal): Rename as...
7735 ($uses_aclocal): this.
7736 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7737 Suggested by Bruno Haible.
7739 2002-05-03 Akim Demaille <akim@epita.fr>
7741 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7743 2002-04-29 Paul Eggert <eggert@twinsun.com>
7745 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7746 files to be 1 second older; just set them to be the same time.
7747 Also, sleep 1 second after the first aclocal, to work around
7748 problems with sub-second time stamps on the input files.
7750 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7752 * doc/autoconf.texi: Mention "set -e -x" lossage
7753 under node "Limitations of Builtins".
7755 2002-04-29 Akim Demaille <akim@epita.fr>
7757 * doc/install.texi: Better wording for setting variables when
7758 running configure.
7759 From Christian Cornelssen.
7761 2002-04-29 Akim Demaille <akim@epita.fr>
7763 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7764 of lack of $LINENO support, then the test will compare the $LINENO
7765 in testsuite vs. the lineno in the test file. This is wrong, of
7766 course.
7767 Be sure to protect it.
7768 Reported by Patrick Welche.
7770 2002-04-25 Akim Demaille <akim@epita.fr>
7772 * doc/autoconf.texi (Obsolete Macros): Typo.
7773 Reported by Vladimir Volovich.
7775 2002-04-25 Akim Demaille <akim@epita.fr>
7777 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7778 than some of the input files, hence, on the second run of aclocal,
7779 if some of its input are younger, make them older.
7780 Suggested by Paul Eggert.
7782 2002-04-25 Akim Demaille <akim@epita.fr>
7784 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
7785 Thanks to Paul Eggert.
7787 2002-04-25 Akim Demaille <akim@epita.fr>
7789 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7790 and ac_subst_vars be sh variables containing the list of
7791 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7792 DEFAULT diversion.
7793 (_AC_INIT_PREPARE): Use them to log them.
7794 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7795 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7796 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7797 _AC_SUBST_FILES and _AC_SUBST_VARS.
7798 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7800 2002-04-24 Akim Demaille <akim@epita.fr>
7802 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7803 autoheader, so that automake does not complain about a missing
7804 config.h.in that was to be created.
7806 2002-04-23 Akim Demaille <akim@epita.fr>
7808 * bin/autoheader.in (parse_args): --warning takes an argument.
7809 Fixes PR/220.

7858 Minor spelling and grammar fixes.
7860 * doc/autoconf.texi: Follow the outline suggested in the GNU
7861 Sample Texts sections of the Texinfo 4.2 manual. Most
7862 importantly, this makes sure that the copyright notices appear in
7863 all output formats. You probably need Texinfo 4.2 to generate
7864 the manual now.

7899 2002-04-10 Akim Demaille <akim@epita.fr>
7901 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
7902 workaround for ${1+"$@"}.
7903 * doc/autoconf.texi (Shell Substitutions): Explain it.
7904 From Oliver Kiddle and Peter Stephenson.
7906 Have M4sh perform minimal shell sanitizing.
7908 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
7909 part into...
7910 (_AS_PREPARE): this new macro.
7911 (AS_PREPARE): New.
7912 (AS_INIT): Invoke AS_SHELL_SANITIZE.
7913 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
7915 Adjust Autoconf and Autotest.
7917 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
7918 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
7919 * lib/autotest/general.m4 (AT_INIT): Likewise.
7920 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7921 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
7922 AS_SHELL_SANITIZE.
7924 Use this M4sh to generate Autoconf's shell scripts.
7926 * tests/wrapsh.as: New, precursor of wrapsh.in.
7927 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
7928 on Autotest and M4sh.
7929 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
7930 (wrapsh.in): New target.
7931 * bin/autoconf.as: New, precursor of autoconf.in.
7932 (autoconf.in): New target.
7934 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
7936 * doc/autoconf.texi (Limitations of Make): Mention the issue
7937 with indented comments in rules.
7939 2002-04-09 Andreas Schwab <schwab@suse.de>
7941 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
7942 ac_top_builddir when setting ac_abs_top_builddir.
7944 2002-04-06 Kevin Ryde <user42@zip.com.au>
7946 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
7947 (Portable Shell): Cross reference to Systemology.
7949 2002-04-05 Akim Demaille <akim@epita.fr>
7951 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
7952 directories when descending in a SUBDIRS.
7953 Reported by Ezra Peisach.
7955 2002-04-04 Andreas Schwab <schwab@suse.de>
7957 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
7958 contains no literal separators.
7960 2002-04-03 Akim Demaille <akim@epita.fr>
7962 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
7963 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
7964 Use dnl, not the KILL diversion.
7965 Extracted from...
7966 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
7967 (AC_CONFIG_LINKS): here.
7968 Adjust.
7969 Don't use the KILL diversion, as it kills spurious output, which
7970 results in failures being hidden.
7971 Use m4_defn where appropriate.
7972 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
7973 after the second argument.
7974 Use m4_defn.
7975 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
7976 syntax, as it is provided by M4sugar.
7977 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
7979 2002-04-03 Andreas Schwab <schwab@suse.de>
7981 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
7982 expanded if $# <= 2.

7990 (_AC_COMPILER_EXEEXT_REJECT): New.
7991 Also recognize *.bb and *.bbg as compilation byproducts.
7992 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
7993 (_AC_COMPILER_OBJEXT): Use them.
7994 Fixes Debian #138666.

7998 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
8000 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
8001 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
8002 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
8003 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
8004 (AC_C_CONST): Same.
8005 (AC_C_INLINE): Same.

8014 _AS_MKDIR_P_PREPARE.
8016 2002-03-28 Kevin Ryde <user42@zip.com.au>
8018 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
8019 to avoid versions of HP C which don't allow that.
8021 2002-03-27 Paul Eggert <eggert@twinsun.com>
8023 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
8024 (AS_SHELL_SANITIZE): Invoke it.
8025 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
8027 2002-03-26 Akim Demaille <akim@epita.fr>
8029 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
8031 2002-03-26 Akim Demaille <akim@epita.fr>
8033 * doc/autoconf.texi (Introduction): The GNATS base moved.
8035 2002-03-25 Paul Eggert <eggert@twinsun.com>
8037 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
8038 as POSIX requires, as it doesn't work with Zsh.
8039 * doc/autoconf.texi (Assignments): Document the problem.
8041 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8043 * doc/autoconf.texi (Limitations of Make): Mention more issue
8044 about VPATH, overriding of macros in sub-makes, and handling of
8045 SHELL.
8047 2002-03-21 Paul Eggert <eggert@twinsun.com>
8049 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8050 problem with here-document buffer boundaries.
8052 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8053 when reinvoking the shell, to work around problems with installers
8054 who put strange things like "cd" commands in their environments.
8056 2002-03-19 Akim Demaille <akim@epita.fr>
8058 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
8059 From Aaron Ucko.
8061 2002-03-19 Akim Demaille <akim@epita.fr>
8063 * bin/autoscan.in (scan_file): Specify the location in `&used'
8064 invocations.
8065 From Nicolas Joly.
8067 2002-03-19 Akim Demaille <akim@epita.fr>
8069 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
8070 From Nishio Futoshi.
8072 2002-03-19 Akim Demaille <akim@epita.fr>
8074 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

8078 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8079 (Limitations of Usual Tools): Add mkdir section.
8081 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8082 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8083 back on AS_DIRNAME to compute prefixes otherwise; this is
8084 roughly what mkinstalldirs does. That way, we need not have
8085 our own filename disassembler. The old disassembler did not
8086 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8088 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8089 Create at_test_all by a series of assignments,
8090 not by a single assignment of a long string. The latter causes ksh
8091 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8092 presumably because of a buffer overrun.
8094 2002-03-14 Paul Eggert <eggert@twinsun.com>
8096 * lib/autotest/general.m4 (at_times_skip):
8097 Renamed from at_times. Now a boolean.
8098 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8099 says 'times: not found'.
8101 2002-03-14 Akim Demaille <akim@epita.fr>
8103 * bin/autoreconf.in (&study_gettextize): New.
8104 (&autoreconf): Handle newest gettextize.
8105 Rerun aclocal if needed.
8106 Suggested by Andreas Schwab.
8108 2002-03-13 Akim Demaille <akim@epita.fr>
8110 * doc/autoconf.texi (Special Shell Variables): More about IFS.
8112 2002-03-13 Akim Demaille <akim@epita.fr>
8114 * doc/autoconf.texi (Header Portability): New.
8115 Add information about stdint.h and inttypes.h from Paul Eggert.
8117 2002-03-13 Akim Demaille <akim@epita.fr>
8119 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
8120 -p'.
8121 From Bob Proulx.
8123 2002-03-12 Akim Demaille <akim@epita.fr>
8125 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
8126 m4_require.
8128 2002-03-11 Andreas Schwab <schwab@suse.de>
8130 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
8131 does not do it if --with-lispdir is given.
8133 2002-03-08 Akim Demaille <akim@epita.fr>
8135 Version 2.53.
8137 2002-03-08 Akim Demaille <akim@epita.fr>
8139 * doc/autoconf.texi (Subdirectories): Clarify that the
8140 subdirectory should exist.
8142 2002-03-08 Akim Demaille <akim@epita.fr>
8144 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
8146 2002-03-08 Akim Demaille <akim@epita.fr>
8148 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8149 aliases the actual variables, and modifications of the former
8150 affect the latter.
8152 2002-03-08 Akim Demaille <akim@epita.fr>
8154 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8155 because of C-c: have m4 output in tmp files, then mv them.
8157 2002-03-08 Akim Demaille <akim@epita.fr>
8159 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
8160 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
8161 * bin/ifnames.in: Copyright update.
8163 2002-03-08 Akim Demaille <akim@epita.fr>
8165 * doc/autoconf.texi (Invoking autom4te): New.
8167 2002-03-05 Akim Demaille <akim@epita.fr>
8169 * doc/autoconf.texi (Specifying Names): Clarification suggested by
8170 Kevin Ryde.
8172 2002-03-05 Akim Demaille <akim@epita.fr>
8174 Version 2.52i.
8176 2002-03-04 Akim Demaille <akim@epita.fr>
8178 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
8179 * lib/autoconf/general.m4 (AC_INIT): More informative error
8180 message for LIBOBJ.
8182 2002-03-04 Akim Demaille <akim@epita.fr>
8184 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
8185 parallel builds.
8187 2002-03-04 Akim Demaille <akim@epita.fr>
8189 * doc/autoconf.texi (Transforming Names): Equality between target
8190 and host is irrelevant.
8191 (Specifying Names, Canonicalizing): Remove all references to the
8192 backward compatibility hooks. Rather, collect them all into...
8193 (Hosts and Cross-Compilation): this new section.
8194 * doc/install.texi (System Type): Ditto.
8195 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8196 that `--host' implies cross-compilation.
8198 2002-03-04 Akim Demaille <akim@epita.fr>
8200 * doc/autoconf.texi (Evaluation Macros): New.
8201 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8202 useless.
8203 (_m4_foreach): Define the variant with immediate evaluation so
8204 that it contains exactly the items, not an expression which
8205 evaluation is the current item.
8206 (m4_re_string, m4_re_word): Don't over quote them.
8208 2002-03-04 Akim Demaille <akim@epita.fr>
8210 Instead of having stacking `shift's evaluated at the end, let
8211 `foreach' loops immediately evaluate them.
8213 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8214 $*. This is the n-th time I change my mind, but hopefully this is
8215 the last...
8216 (m4_lquote): New.
8217 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8218 efficient.
8219 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8220 it was only a hack for m4_text_wrap.
8221 (m4_car2): Remove, replaced by...
8222 (m4_cdr): New.
8223 (_m4_foreach): Adjust.
8224 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8225 m4_bpatsubst for clarification.
8227 2002-03-04 Akim Demaille <akim@epita.fr>
8229 * doc/autoconf.texi (Changequote is Evil): New.
8231 2002-03-03 Kevin Ryde <user42@zip.com.au>
8233 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
8234 on old systems like SunOS.
8236 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
8238 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8239 lib/autoconf/functions.m4, lib/autoconf/general.m4,
8240 lib/autoconf/headers.m4, lib/autoconf/lang.m4,
8241 lib/autoconf/programs.m4, lib/autoconf/status.m4: Improve spelling
8242 of messages.
8244 2002-02-28 Akim Demaille <akim@epita.fr>
8246 * lib/autotest/general.m4 (AT_INIT): Suggest a title to the
8247 message to be sent.
8249 2002-02-28 Kevin Ryde <user42@zip.com.au>

8253 2002-02-25 Akim Demaille <akim@epita.fr>
8255 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
8256 From Akinori Musha.
8258 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
8260 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
8261 translate \r\n to \n.
8263 2002-02-07 Akim Demaille <akim@epita.fr>
8265 Version 2.52h.
8267 2002-02-07 Akim Demaille <akim@epita.fr>
8269 Fix Autoconf PR/209.
8270 Also reported by Frank Denis.
8272 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
8274 2002-02-07 Akim Demaille <akim@epita.fr>
8276 Fix Autoconf PR/207:
8277 AC_PREFIX_PROGRAM fails with dashed program names
8279 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
8280 variable when looking for the prefix program.
8281 Now it also works for shell variables.
8283 2002-02-07 Akim Demaille <akim@epita.fr>
8285 * doc/autoconf.texi (Limitations of Builtins): More about
8286 case/esac.
8288 2002-02-06 Akim Demaille <akim@epita.fr>
8290 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
8291 case/esac, some shells don't support it.
8292 Reported by Zack Weinberg.
8293 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
8295 2002-02-06 Akim Demaille <akim@epita.fr>
8297 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
8298 sure not to introduce newlines in at_groups.
8299 * lib/autotest/Makefile.am (autotest.m4f): Typo.
8301 2002-02-06 Akim Demaille <akim@epita.fr>
8303 * tests/torture.at (Configuring subdirectories): Skip if aclocal
8304 is not available.
8306 2002-02-05 Paul Eggert <eggert@twinsun.com>
8308 * doc/autoconf.texi (Specific Compiler Characteristics):
8309 Describe HP-UX cc bug workaround more accurately.
8310 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
8311 not unsigned long.
8312 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
8313 cross-compilers, too. This undoes some of the most recent change
8314 to this file.
8316 2002-02-05 Akim Demaille <akim@epita.fr>
8318 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
8319 to make sure they are up to date when `check' is run.
8321 2002-02-05 Akim Demaille <akim@epita.fr>
8323 * doc/autoconf.texi (Making testsuite Scripts): Document
8324 package.m4.
8326 2002-02-05 Akim Demaille <akim@epita.fr>
8328 * lib/freeze.mk: New.
8330 2002-02-05 Akim Demaille <akim@epita.fr>
8332 Implement `autom4te --freeze'.
8334 * bin/autom4te.in (&freeze): New.
8335 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
8336 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
8338 2002-02-05 Akim Demaille <akim@epita.fr>
8340 * bin/autom4te.in (&parse_args): Implement `frozen files are
8341 optional are the sum of the previous files on the command line'.
8342 Also, pass `--reload-state=' on them, so...
8343 (handle_m4): don't.
8344 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8345 (M4sh): Rely on M4sugar.
8346 (Autotest, M4sh, M4sugar): Use frozen files.
8348 2002-01-31 Akim Demaille <akim@epita.fr>
8350 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
8351 * doc/autoconf.texi (Initializing configure): Adjust.
8353 2002-01-30 Akim Demaille <akim@epita.fr>
8355 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8356 alphanumeric to `-' instead of `_'.
8358 2002-01-30 Akim Demaille <akim@epita.fr>
8360 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8361 for plain code, the other for cross-compilation code. The latter
8362 is now run with GCC only.
8363 * doc/autoconf.texi (Compilers and Preprocessors): New.
8365 2002-01-30 Akim Demaille <akim@epita.fr>
8367 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
8368 values.
8369 * doc/autoconf.texi (Initializing configure): Explain how to
8370 change AC_INIT default values.
8372 2002-01-29 Akim Demaille <akim@epita.fr>
8374 * tests/torture.at (Configuring subdirectories): Use configure.in,
8375 so that aclocal 1.4 works.
8376 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8378 2002-01-28 Akim Demaille <akim@epita.fr>
8380 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8381 needs an argument.
8383 2002-01-28 Akim Demaille <akim@epita.fr>
8385 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8386 AUTOTEST_PATH *after* it was set.
8387 Don't put `.' in the PATH: the user should be precise and `./' if
8388 needed. In addition, given that the test suite does some `cd', if
8389 `.' is in the path, the `tested programs' sections will report
8390 programs found in the test suite's directory, while during the
8391 tests (performed in their own directory), these programs are no
8392 longer visible. In other words, the results is confusing and
8393 useless.
8394 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8396 2002-01-24 Akim Demaille <akim@epita.fr>
8398 Version 2.52g.
8400 2002-01-24 Akim Demaille <akim@epita.fr>
8402 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
8403 * doc/autoconf.texi: Finally add Akim as an author.

8421 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
8422 * config/missing.m4, config/sanity.m4, config/select.m4,
8423 * config/strip.m4: Remove, to ease sync'ing with any version of
8424 Automake.
8426 2002-01-24 Akim Demaille <akim@epita.fr>
8428 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
8429 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
8430 Reported by Geir Ove Myhr.
8432 2002-01-21 Akim Demaille <akim@epita.fr>

8436 2002-01-21 Akim Demaille <akim@epita.fr>
8438 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
8439 message on invalid options.

8459 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8460 package.m4, since is really depends upon configure.ac, not
8461 configure.
8462 * doc/autoconf.texi (testsuite Scripts): Adjust.
8463 * tests/Makefile.am (package.m4): New.
8464 EXTRA_DIST it since its a source.
8466 2002-01-06 Akim Demaille <akim@epita.fr>
8468 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8469 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8470 and PACKAGE_BUGREPORT from here...
8471 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8472 arguments.
8473 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8474 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

8483 2002-01-03 Akim Demaille <akim@epita.fr>
8485 * doc/autoconf.texi (Output): Improved wording regarding use of
8486 AC_OUTPUT.

8492 sometimes needing writable input.
8494 2001-12-17 Jim Meyering <meyering@lucent.com>
8496 * doc/autoconf.texi (New Macros): Tweak wording.
8498 2001-12-14 Akim Demaille <akim@epita.fr>
8500 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8501 trailing files, don't apply `-rf' to files which might not be
8502 created by configure (core, core.*, and *.core), but just `rm -f'.
8503 Suggested by Jonathan Kamens.
8505 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8507 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8509 2001-12-14 Akim Demaille <akim@epita.fr>
8511 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8513 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

8516 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
8517 abs_srcdir, top_srcpath to abs_top_srcdir.
8518 (_AC_OUTPUT_FILES): Adjust.
8519 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
8520 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
8521 * tests/wrappl.in, tests/wrapsh.in: Adjust.
8523 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8525 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
8526 C/Fortran linking on HP/UX, by extracting the Fortran library
8527 search path from the LPATH line in the $F77 -v output.
8529 2001-12-12 Kevin Ryde <user42@zip.com.au>
8531 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
8532 forbidden file descriptors table.
8534 2001-11-26 Akim Demaille <akim@epita.fr>
8536 * bin/autoscan.in (%c_keywords): Build it at top level.
8537 Map to 1 in order to simplify its uses.
8539 2001-11-26 Akim Demaille <akim@epita.fr>
8541 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8542 Remove $filepath, useless.
8543 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8544 variables, they are really part of the tokens.
8545 Split the input line on spaces and then look for tokens.
8546 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8547 because of `lex$U.$(OBJEXT)'.
8548 (&scan_files): Use "@list" instead of join.
8549 * doc/Makefile.am (CLEANFILES): Add *.fns.
8551 2001-11-26 Akim Demaille <akim@epita.fr>

8554 Remove, replaced by...
8555 * tests/wrappl.in: Be common for all the Perl executables.

8558 * lib/autoscan/headers: errno.h is portable.
8560 2001-11-26 Akim Demaille <akim@epita.fr>
8562 * bin/autoscan.in (used): New.
8563 Use it.
8565 2001-11-26 Akim Demaille <akim@epita.fr>
8567 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
8568 directives.
8569 (&scan_sh_file): Remove a duplicate pattern.
8570 (&check_configure_ac): Use long options.
8571 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
8573 2001-11-26 Akim Demaille <akim@epita.fr>
8575 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
8576 Before, having a line containing the opening of a multi line
8577 comment made the whole line be ignored.
8579 2001-11-26 Akim Demaille <akim@epita.fr>
8581 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8582 (testsuite Scripts): Be one of its subsection.
8583 (Autotest Logs): New.
8585 2001-11-26 Akim Demaille <akim@epita.fr>
8587 Test groups are now run two directories deeper.
8589 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8590 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8591 at_top_builddir.
8592 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8593 top_srcdir, builddir and top_builddir.
8594 Use `at_*dir' relatively to the directory containing the
8595 suite, use `*dir' when relatively to the current group dir.
8597 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8599 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8600 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8601 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8602 spelling errors.
8604 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8606 * doc/autoconf.texi (Using System Type): Add an example of `case
8607 $host' usage so people quit using `case $target' everywhere.
8609 2001-11-22 Akim Demaille <akim@epita.fr>
8611 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8612 spotted by Jim Meyering.
8614 2001-11-16 Paul Eggert <eggert@twinsun.com>
8616 This patch implements a `long double' suggestion by Oliver Kiddle.
8618 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8619 static, to catch errors if the value isn't known at compile-time
8620 and the compiler supports dynamic arrays. Change its name from
8621 `_array_' to `test_array' to avoid potential name clashes.
8622 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8623 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8624 better than double. Catch a bug in GCC 2.95.2 x86.
8625 * doc/autoconf.texi (C Compiler): Document the above.
8626 * NEWS: Likewise.
8628 2001-11-13 Akim Demaille <akim@epita.fr>
8630 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8631 hand.
8632 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8634 2001-11-13 Akim Demaille <akim@epita.fr>
8636 * lib/autotest/general.m4 (AT_INIT): After having run the test
8637 group, go back to the initial directory, not to at_suite_dir.
8639 2001-11-13 Akim Demaille <akim@epita.fr>
8641 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8642 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8643 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8644 option.
8645 (AT_CHECK_CONFIGURE): Use absolute paths.
8646 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8647 The problem is still the old one: there is no means in M4 (that I
8648 know about) to create a defining macro, because there is no means
8649 to create `$1' etc., therefore, the defining macro ``swallows''
8650 all the arguments meant to the defined macro.
8652 2001-11-13 Akim Demaille <akim@epita.fr>
8654 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8655 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8656 configure.ac.
8657 * tests/aclocal.m4: Remove, as it is no longer used.
8659 2001-11-13 Akim Demaille <akim@epita.fr>
8661 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8662 variable names when referring to a single test group, or to
8663 `suite' when referring to the whole test suite.
8664 `at_last_test' is removed: m4 compute at_format itself.
8665 (at_stdout, at_stder1, at_stderr): New variables.
8666 (AT_CHECK): Use them.
8668 2001-11-13 Akim Demaille <akim@epita.fr>
8670 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8671 in PATH.
8672 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8673 Do it as soon as a test fails, don't wait till the end of the test
8674 suite.
8675 Don't remove $as_me.[0-9]*, since these files no longer exist.
8677 2001-11-13 Akim Demaille <akim@epita.fr>
8679 * tests/tools.at: Use absolute paths, since we are no longer run
8680 in place.
8682 2001-11-13 Akim Demaille <akim@epita.fr>
8684 Now that tests are running in their own private dir, there is no
8685 need to list the files to remove at the end of tests groups.
8687 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8688 (AT_data_files, at_data_files): Remove.
8689 (AT_CLEANUP, AT_DATA): Simplify.
8690 (AT_INIT): Adjust.
8691 Remove the group dir if !debug && !failed.
8692 * tests/atspecific.m4: Adjust.
8694 2001-11-13 Akim Demaille <akim@epita.fr>
8696 Start a new layout for Autotest: `testsuite' creates
8697 `testsuite.dir' in which the at-check-line etc. files are to be
8698 found, and `testsuite.dir/003' where the test group 3 is run.
8700 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8701 at_check_line_file, at_format, at_test_normalized, at_group_dir
8702 are new variables.
8703 Create the directories.
8704 Use absolute paths for at- files.
8705 (AT_CHECK): Adjust.
8707 2001-11-11 Michael Matz <matz@kde.org>
8709 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8710 (m4_car2): New.
8711 (m4_car): Properly quote arguments.
8713 2001-11-13 Akim Demaille <akim@epita.fr>
8715 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8716 with stricter rules on LIBOBJS.
8718 2001-11-12 Paul Eggert <eggert@twinsun.com>
8720 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8721 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8722 __PROTOTYPES too.
8724 2001-11-12 Akim Demaille <akim@epita.fr>
8726 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8728 2001-11-12 Akim Demaille <akim@epita.fr>
8730 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8731 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8732 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8733 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8734 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8735 specify to what the macro should be defined (typically to 1).
8737 2001-11-12 Akim Demaille <akim@epita.fr>
8739 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8740 From Jim Meyering.
8742 2001-11-12 Akim Demaille <akim@epita.fr>
8744 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8745 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8746 definition used by Automake where LEX is +/- "${missing} lex" and
8747 `missing' itself contains variables.
8749 2001-11-12 Akim Demaille <akim@epita.fr>
8751 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8752 Now that M4sh pushes BODY, the comments were output at the end of
8753 the test suites.
8755 2001-11-08 Akim Demaille <akim@epita.fr>
8757 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8758 that we can trace macros from aclocal.m4.
8759 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8760 obsoleted, and redirect to the former anyway.
8761 Reported by Ralf Corsepius.
8763 2001-11-08 Akim Demaille <akim@epita.fr>
8765 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8766 processed only if present.
8767 * tests/torture.at (Configuring subdirectories): Use autoreconf
8768 instead of successive calls to autoconf.
8769 Add a nonexistent subdirectory to exercise the patch above.
8770 Reported by Ralf Corsepius.
8772 2001-11-08 Kevin Ryde <user42@zip.com.au>
8774 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8775 doesn't accept .S files.
8777 2001-11-07 Akim Demaille <akim@epita.fr>
8779 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
8780 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
8781 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
8782 * bin/autom4te.in (warn_forbidden): New.
8783 (handle_output): Use it.
8784 Read m4_pattern_forbid with messages.
8786 2001-11-05 Akim Demaille <akim@epita.fr>
8788 * bin/autom4te.in (--normalize): Remove.
8789 * lib/autom4te.in: Adjust.
8791 2001-11-05 Akim Demaille <akim@epita.fr>
8793 * tests/Makefile.am (testsuite): Rename this target as...
8794 ($(TESTSUITE)): this.
8795 From Nicolas Joly.
8797 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8799 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
8800 the --prefix option, also remove it's argument.
8802 2001-11-05 Akim Demaille <akim@epita.fr>
8804 * doc/autoconf.texi (testsuite Invocation): Update.
8805 (Writing testsuite.at): Update.
8807 2001-11-03 Akim Demaille <akim@epita.fr>
8809 * doc/autoconf.texi: s/@code/@command/ where appropriate.
8811 2001-11-03 Akim Demaille <akim@epita.fr>
8813 * lib/Autom4te/General.pm: (&catfile, &canonfile)
8814 (&file_name_is_absolute): New, wrappers around routines from
8815 File::Spec.
8816 Use and export them.
8817 (&find_configure_ac): Optionally take a directory where to look at.
8818 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8819 the arguments.
8820 Default @ARGV to `.', not find_configure_ac.
8821 (&autoreconf): Argument is a directory.
8822 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8823 * doc/autoconf.texi (autoreconf Invocation): Update.
8825 2001-11-03 Akim Demaille <akim@epita.fr>
8827 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8828 (@export_forward_subs): New.
8829 Add basename, dirname, and fileparse.
8830 (@EXPORT): Adjust.
8831 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8832 Don't look for aclocal flags if we already know aclocal is not
8833 used.
8834 Move aclocal.m4t only if it exists.
8835 Reported by Ezra Peisach.
8837 2001-11-03 Akim Demaille <akim@epita.fr>
8839 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8840 passed on command line, defaulting to ./configure.ac if present.
8841 (&maybe_autoreconf, File::Find): Remove, unused.
8842 (&autoreconf): If autoconf is not used, don't try to trace.
8844 2001-11-02 Akim Demaille <akim@epita.fr>
8846 * configure.ac: Bump to 2.52g.
8848 2001-11-02 Akim Demaille <akim@epita.fr>
8850 Version 2.52f.
8852 2001-11-02 Akim Demaille <akim@epita.fr>
8854 * config/config.guess, config/config.sub, doc/standards.texi:
8855 * config/lispdir.m4: Update from masters.
8856 * configure.ac: Bump to 2.52f.
8858 2001-11-02 Akim Demaille <akim@epita.fr>
8860 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8861 Don't run aclocal when aclocal.m4 is not from aclocal.
8862 From Ezra Peisach.
8863 Don't run libtoolize and gettextize if --install is not given.
8865 2001-11-01 Paul Eggert <eggert@twinsun.com>
8867 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8868 be invoked before _AS_LINENO_PREPARE.
8869 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8870 than character ranges.
8872 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8873 invoking AS_BASENAME. Set the locale variables to 'C' if
8874 possible, as POSIX requires this to get the traditional
8875 behavior.
8876 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8878 2001-10-31 Paul Eggert <eggert@twinsun.com>
8880 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8881 with {}, as that triggers a bug in Bash 2.05.
8883 (_AS_LINENO_PREPARE): Use Sed rather than
8884 Awk. Fix the sed prepass to work even if there are multiple
8885 instances of $LINENO on the same line. Do not substitute for
8886 other variables like $LINENOT. Do not check file dates; such a
8887 check is unreliable on sufficiently fast machines, and removing
8888 the check makes the code simpler and more reliable. Check for
8889 output and chmod failures.
8891 * doc/autoconf.texi (Special Shell Variables): Document
8892 the above.
8894 2001-10-31 Akim Demaille <akim@epita.fr>

8901 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not

8906 2001-10-26 Paul Eggert <eggert@twinsun.com>
8908 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8909 lib/Autom4te/Struct.pm:
8910 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8911 with 5.005_02.
8913 * doc/autoconf.texi (Special Shell Variables): Document some
8914 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8916 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8917 (_AS_LINENO_PREPARE): Use it instead of shell eval, since

8937 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8938 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8939 POSIX decided to standardize on the int flavor of strerror_r.
8940 Always do char* test, as there's no reason not to.
8941 Assign to a char* var, to catch strerror_r that returns int*.
8943 * doc/autoconf.texi (Particular Functions):
8944 Document the above changes. Also, document the fact that
8945 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.

8971 * bin/autoreconf.in (&autoreconf): Do not run gettextize when

8973 (&parse_args): Use -I, --include instead of the old Autoconf
8974 options.
8975 ($localdir, $autoconf_dir): Remove.
8976 (@include): New.

9000 configure.ac being studied.
9002 2001-10-18 Paul Eggert <eggert@twinsun.com>
9004 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned

9015 contains white space.
9016 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

9018 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9019 Allow "dirname //FOO" to return either / or //, as POSIX allows
9020 either behavior.

9166 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

9251 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

9284 (AC_PROG_CPP requires AC_PROG_CC): here and...
9285 * tests/fortran.at (GNU Fortran 77): there.
9286 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9287 AC_TRY_RUN is about compilation, not shell commands.

9293 Raja R Harinath:

9301 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

9370 * lib/Autom4te/General.pm (&debug): New.
9371 * bin/autom4te.in ($language): Move to...
9372 (parse_args): here.
9373 Handle --language in languages.
9374 * lib/autom4te.in (Automake-selections, Autoheader-selections)
9375 (Autoscan-selections): New.
9376 (Autoconf): Adjust.

9389 2001-09-22 Akim Demaille <akim@epita.fr>
9391 * lib/autoconf/autotest.m4: Create `package.m4'.
9392 * tests/Makefile.am (package.m4): Remove.
9394 2001-09-22 Akim Demaille <akim@epita.fr>
9396 Rely on `$LINENO' when possible instead of `__oline__'.
9398 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
9399 `$LINENO' support replacement when not supported.
9400 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
9401 them explicitly to be sure they are not output before this section
9402 (via m4_require). Cosmetic only.
9403 * lib/autoconf/c.m4, lib/autoconf/general.m4,
9404 * lib/autoconf/programs.m4: Replace all the occurrences of
9405 `__oline__' with `$LINENO'.
9406 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
9408 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
9410 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
9411 character (u: -> ue) in a code comment.
9412 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
9413 it works.
9415 2001-09-21 Akim Demaille <akim@epita.fr>
9417 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
9418 Suggested by Jim Meyering.
9420 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9422 * lib/autoconf/programs.m4: Use extensions listed in

9429 setting up ac_dir_suffix and ac_top_builddir.
9430 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
9432 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9434 * doc/autoconf.texi (File System Conventions): Clarify the use of
9435 PATH_SEPARATOR.
9436 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
9437 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9438 be used instead of ':'.
9439 * lib/autotest/general.m4: Replace occurrences of ':' in
9440 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
9442 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9444 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
9445 arguments. Fixed a typo.
9447 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9449 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
9450 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
9452 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9454 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

9461 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9463 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
9464 already have $file). Set output files to binary mode (helps avoid
9465 CR issues on DOSish systems).
9467 2001-09-19 Akim Demaille <akim@epita.fr>
9469 * lib/autotest/general.m4: Englishoes.
9470 From Tim Van Holder and Alexey Mahotkin.
9472 2001-09-18 Paul Eggert <eggert@twinsun.com>
9474 * doc/autoconf.texi (Common Shell Constructs): New node,
9475 documenting AS_DIRNAME.
9476 (Limitations of Usual Tools): Refer to it when discussing dirname.
9477 Also, update discussion of POSIX standard to reflect latest draft.
9479 * lib/autoconf/c.m4:
9480 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9482 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9483 Do not pass a first argument with leading '-'
9484 to expr, by parenthesizing initial integers that might be negative.
9486 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9487 now merely checks whether it is an error to pass an argument
9488 to getpgrp.
9490 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9491 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9492 whether it is a (compile-time) error to pass an argument to
9493 getpgrp. This simpler test supports the revised documentation,
9494 and is all that AC_FUNC_GETPGRP's users really need.
9496 2001-09-18 Akim Demaille <akim@epita.fr>
9498 * doc/autoconf.texi (Limitations of Make) <$<>: New.
9500 2001-09-18 Akim Demaille <akim@epita.fr>

9506 2001-09-18 Paul Wagland <paul@wagland.net>
9508 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9509 correctly.
9510 Add test for AS_BASENAME.
9511 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9512 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9513 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9514 * tests/base.at: Fixed the expected responses. The old ones were
9515 one line out...
9516 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9517 the documentation claims it should (and how it behaved in 2.13).
9519 2001-09-18 Akim Demaille <akim@epita.fr>
9521 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9522 the AC_CONFIG_COMMANDS invocation.
9523 This also solves the name clash problems.
9524 Don't set the package's ID.
9525 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9526 No longer to be shipped.
9527 (version.in): Remove.
9528 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
9529 * lib/autoconf/status.m4: Adjust.
9530 Use `m4_PACKAGE_STRING'.
9531 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9532 the only optional argument is the name of the test suite.
9533 Expect `package.m4' to define the package signature.
9534 * lib/autom4te.in (Autotest): Add `package.m4?'.
9535 * tests/Makefile.am (package.m4): New.
9536 * tests/suite.at: ifnames is a victim.
9538 2001-09-18 Akim Demaille <akim@epita.fr>
9540 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9541 AC_LIBSOURCE, AC_CONFIG_FILES.
9542 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
9543 program version string doesn't match the package's.
9544 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9545 after `(cached)'.
9547 2001-09-17 Paul Eggert <eggert@twinsun.com>
9549 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9550 Allow expression to return any value that can fit into unsigned long
9551 (not int, as before). Check for output errors.
9553 2001-09-17 Bruno Haible <haible@ilog.fr>
9555 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9556 Always include <stdio.h> and <stdlib.h>. Evaluate
9557 the expression in an extra function before these includes. Call
9558 fprintf "%d" only after ensuring the argument is of type 'int'.
9559 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9561 2001-09-17 Paul Eggert <eggert@twinsun.com>
9563 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9564 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9565 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9566 when they don't exist.
9568 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9569 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9570 need it.
9572 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9573 version with the version used by fileutils 4.1, except use
9574 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
9575 we don't need it.
9577 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
9579 2001-09-13 Akim Demaille <akim@epita.fr>
9581 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
9582 _first_.
9583 Reported by Gerrit P. Haase.
9585 2001-09-13 Akim Demaille <akim@epita.fr>
9587 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

9603 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
9604 Likewise.
9605 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
9606 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
9607 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
9608 AT_tests_all for consistency.

9610 (AT_VICTIMS): Similar to AT_KEYWORDS.
9611 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
9613 2001-09-13 Akim Demaille <akim@epita.fr>
9615 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
9617 2001-09-13 Akim Demaille <akim@epita.fr>
9619 * lib/autotest/general.m4 (AT_INIT): Create and remove
9620 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
9621 test suites can cohabit.
9623 2001-09-13 Akim Demaille <akim@epita.fr>
9625 * tests/mktests.sh: Don't output banners for empty test files.
9627 2001-09-13 Akim Demaille <akim@epita.fr>
9629 Test suites can be run independently of configure.
9631 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.

9671 (m4_list_append): Remove.
9673 Spread a few keywords in the Autoconf test suite.
9675 2001-09-10 Akim Demaille <akim@epita.fr>
9677 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
9678 PATH_SEPARATOR, let M4sh compute it.
9679 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): New.
9680 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

9693 2001-09-07 Akim Demaille <akim@epita.fr>
9695 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
9696 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
9697 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
9698 related variables into `at_package_*'.
9699 * lib/autotest/general.m4 (AT_VICTIMS): New.

9713 Adjust PATH computation.

9724 to avoid GCC warnings.
9725 From Uwe Seimet.
9727 2001-09-05 Akim Demaille <akim@epita.fr>
9729 * bin/autom4te.in: --language is -l, not -s.
9731 2001-09-05 Akim Demaille <akim@epita.fr>
9733 Be ready to handle filenames as stupid as `dnl.at', for if even
9734 the maintainer is dumb enough to do that...
9736 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9737 excellence in M4 quotation: consider `__file__' is active.
9739 And BTW, when invoking m4, pass the --include in the right order:
9740 the wrong one.
9742 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
9743 4m.

9759 * bin/autoheader.in, bin/autoupdate.in (&parse_args): Adjust.
9761 * bin/autoscan.in: Use `getopt' and `find_files' etc.
9762 Add -I, --include support.
9763 * doc/autoconf.texi (autoscan Invocation): Adjust.
9765 2001-09-05 Akim Demaille <akim@epita.fr>
9767 CVS GNU M4 doesn't like `undefine(undefined)'.
9769 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
9770 New, extracted from main.
9771 Use IO::File wherever possible.
9772 (input.m4): Be constant, use -I instead of hard coding $tmp.
9773 Therefore be a quoted heredoc.
9774 Don't invoke `_au_disable', since ac was not loaded, but just
9775 `unm4.m4'.
9777 2001-08-31 Akim Demaille <akim@epita.fr>
9779 Version 2.52d.
9781 2001-08-31 Akim Demaille <akim@epita.fr>

9784 previous patch.

9802 2001-08-31 Akim Demaille <akim@epita.fr>
9804 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
9805 (testsuite Scripts): There is no such thing as `atconfig.in'.
9806 And actually one diagram is missing: test suite runtime.
9808 2001-08-31 Akim Demaille <akim@epita.fr>
9810 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9811 inverse order.
9813 2001-08-31 Akim Demaille <akim@epita.fr>
9815 * bin/autoupdate.in (@include): `installcheck' revealed the path
9816 to m4sugar was lacking!
9818 2001-08-31 Akim Demaille <akim@epita.fr>
9820 * man/Makefile.am (.x.1): We really have to pass
9821 autom4te_perllibdir.
9823 2001-08-31 Akim Demaille <akim@epita.fr>
9825 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
9826 debug scripts, in particular passing explicitly listed tests to
9827 run is stupid.
9829 2001-08-31 Akim Demaille <akim@epita.fr>
9831 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9832 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9833 Use directly autom4te, not autoconf.
9834 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.

9845 2001-08-31 Akim Demaille <akim@epita.fr>
9847 * bin/autom4te.in (&parse_args): Die on unknown languages.
9848 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
9849 need for autoconf.
9850 Promote --include over --macrodir and other obsolete options.
9852 2001-08-31 Akim Demaille <akim@epita.fr>
9854 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
9855 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
9856 * bin/autom4te.in ($autoconf): Pass --force.
9857 `print $out' doesn't print `$_' but `$out'.
9858 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9859 (autoheader): Pass --force since the test suite goes too fast for
9860 the time stamps.
9861 Adjust to the new autoheader messages.
9863 2001-08-31 Akim Demaille <akim@epita.fr>
9865 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
9866 Check the completeness of the #template.

9869 invocation.
9871 2001-08-31 Akim Demaille <akim@epita.fr>
9873 * lib/Autom4te/General.pm (&find_file, &update_file): New.
9874 * bin/autoupdate.in, bin/autoheader.in: Adjust.
9875 Drop AC_MACRODIR dead for real.
9876 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
9877 `autoheader: `config.hin' is created'.
9878 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
9880 2001-08-31 Akim Demaille <akim@epita.fr>
9882 * bin/autoheader.in: Rewrite in Perl.
9883 * tests/autoheader: Adjust.
9885 2001-08-31 Akim Demaille <akim@epita.fr>
9887 * bin/autoconf.in (--include, -I): New option.
9888 Map --localdir, --autoconf-dir onto it.
9889 Forward autom4te's options instead of interpreting them.
9890 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
9891 There is no such envvar since the inception of autom4te.cfg.
9892 * bin/autom4te.in (&parse_args): Uniquify `@include'.
9893 * bin/autoupdate.in: Adjust, and perform more control.
9894 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
9895 * tests/autoconf: Dittowise.
9897 2001-08-31 Akim Demaille <akim@epita.fr>
9899 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
9900 * bin/autom4te.in (&find_file): Support `FILE?' standing for
9901 optionally `FILE'.
9902 Use -e, not -f, since /dev/null for instance is OK.
9903 (&parse_args): Adjust.
9904 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
9906 2001-08-31 Akim Demaille <akim@epita.fr>
9908 * configure.ac: Also find tested executables in bin.
9909 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
9910 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
9911 installed peer executables, only PATH is allowed to resolve it.
9912 Pass `autoconf_dir' via options, not via invisible envvars.
9913 * lib/Autom4te/General.pm (&find_peer): Remove.
9914 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
9915 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
9916 * man/Makefile.am: Let help2man rely on PATH instead of trying to
9917 find the executables for it.
9918 * tests/Makefile.am: Major cleanup. Too lazy to document...
9919 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9920 We only need PERL.
9921 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9922 indeed related to running the test suite, while passing
9923 --autoconf-dir and others is related to running non installed
9924 Autoconf executables. So don't do that, leave it to...
9925 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
9926 * tests/autoscan: New.
9927 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
9928 refer to library files: rely on --language.
9930 2001-08-29 Akim Demaille <akim@epita.fr>
9932 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

9943 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
9944 Suggested by Paul Eggert.
9946 2001-08-29 Akim Demaille <akim@epita.fr>
9948 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
9949 download in a tmp dir.
9951 2001-08-29 Akim Demaille <akim@epita.fr>
9953 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
9954 case insensitive OSes out there :(

9964 (&parse_args): Support --mode, --set, and --melt.
9965 * bin/autoconf.in: Simplify and adjust.
9966 * tests/Makefile.am (AUTOMAKE): Use --set.
9967 * tests/atlocal.in: Adjust.
9968 * BUGS: distcheck and check are weak.
9970 2001-08-29 Akim Demaille <akim@epita.fr>
9972 * lib/autotest/general.m4: Use
9973 foo=`(command) 2>/dev/null`
9974 not
9975 foo=`command` 2>/dev/null
9976 (at-devnull): Rename as...
9977 (AT-devnull): this.
9978 (--clean): Remove AT-* files too.
9979 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
9980 Reported by Nicolas Joly.
9982 2001-08-28 Akim Demaille <akim@epita.fr>
9984 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

9996 Support test ranges as arguments to the testsuite.
9997 Have -e imply -d as the help text suggested.
9999 2001-08-27 Akim Demaille <akim@epita.fr>

10014 * lib/autotest/general.m4 (AT_INIT): Log the command line.
10015 Support `VAR=VAL' as arguments.

10021 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.

10040 available in commands.
10041 Emphasize the risks of collisions in init-cmds.

10074 -> ac_dir).

10106 needed, 1.5 can have a macro and a target with the same name.
10107 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
10108 * m4/strip.m4: New.

10123 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
10124 the name of the directory they're in, instead of the filename,
10125 since version.m4 is now in m4sugar, but m4_acversion must not be
10126 classified as an Autoconf macro.
10127 ($input_m4): Don't qualify the path to m4sugar.
10128 Rather, pass autoconf_dir to m4.
10129 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

10149 Use the same log introduction as configure's.
10151 2001-08-22 Paul Eggert <eggert@twinsun.com>
10153 * doc/autoconf.texi (Indices): New node.
10154 Move indices out of the top level menu and into this submenu.
10156 2001-08-22 Akim Demaille <akim@epita.fr>
10158 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10159 AC_TRY_COMMAND.
10160 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
10162 2001-08-22 Akim Demaille <akim@epita.fr>
10164 * lib/autoconf/general.m4 (AC_SHELL_PATH_WALK, AC_CHECK_PROG)

10208 program with AC_LANG_PROGRAM before feeding it to
10209 AC_COMPILE_IFELSE. Cleanup grep usage.
10211 2001-08-20 Akim Demaille <akim@epita.fr>
10213 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
10214 * NEWS, README, README-alpha, TODO, tests/README: This package is
10215 `Autoconf', not `autoconf' (the executable).
10217 2001-08-20 Akim Demaille <akim@epita.fr>
10219 Info readers seem to need `Index' in the index node title :(
10221 * doc/autoconf.texi: Reverse the 2001-08-15 change which
10222 simplified index node names.
10224 2001-08-20 Akim Demaille <akim@epita.fr>
10226 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
10227 arguments are not literals.
10228 * doc/autoconf.texi (Input) <AC_INIT>: Arguments must be literals.
10229 Specify the output variables, and macros defined.
10231 2001-08-20 Akim Demaille <akim@epita.fr>
10233 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
10234 (Examining Syntax) <AC_TRY_COMPILE>
10235 (Examining Libraries) <AC_TRY_LINK>
10236 (Test Programs) <AC_TRY_RUN>: These macros double quote some of
10237 their arguments.
10238 Reported by Werner Lemberg.
10240 2001-08-20 Akim Demaille <akim@epita.fr>

10257 * lib/autoconf/general.m4 (_AC_OUTPUT_COMMANDS): Say what you do.
10258 * m4/atconfig.m4 (AT_CONFIG): $1 is now the directory where the
10259 test suite lives.
10260 Create `atconfig' automagically.
10261 Configure atlocal.in if present.
10262 * tests/atconfig.in: Remove.

10266 2001-08-20 Akim Demaille <akim@epita.fr>
10268 Huh!?!?! There are still some user EOF tags used, which prevents
10269 their use in AC_CONFIG_COMMANDS for instance...
10271 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
10272 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

10353 * doc/autoconf.texi: Work around Texinfo buglets.

10412 * tests/Makefile.am: Use a clean-local rule to remove

10414 * Makefile.am: Ditto (but maintainer-clean-local).
10416 2001-08-15 Akim Demaille <akim@epita.fr>
10418 * bin/autom4te.in (@m4_warning): New.
10419 (&handle_m4): Use it.

10490 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10492 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10493 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10494 * doc/autoconf.texi (C Compiler Characteristics): Update
10495 documentation for AC_C_BIGENDIAN.
10497 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10499 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10500 magic values from an object file when cross-compiling.
10501 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10503 2001-08-10 Akim Demaille <akim@epita.fr>
10505 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10506 effects.
10507 Suggested by Russ Allbery.
10509 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10511 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10512 current $prefix to the sub-configures.
10514 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10516 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10517 extension (needed on BeOS). Reported by Guido van Rossum.
10519 2001-08-09 Akim Demaille <akim@epita.fr>
10521 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10523 2001-08-07 Akim Demaille <akim@epita.fr>
10525 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10526 removed.
10527 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10528 No need to remove the files before and after the each test, before
10529 each test and at the end of the suite is enough.
10530 Display only the children `times', not the shell's.
10531 If the test failed or was skipped, at-times is not available.
10533 2001-08-07 Akim Demaille <akim@epita.fr>
10535 Always produce testsuite.log, including when there are no
10536 failures. This helps getting information on skipped tests, and
10537 duration of the tests. Err, implement the latter btw.
10539 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10540 Dump information on the first run of each test.
10541 (AT_CLEANUP): Create `at-times' containing the duration of the
10542 test group.
10544 2001-08-07 Akim Demaille <akim@epita.fr>
10546 The use of `dumpstat' revealed that `len' was used although it
10547 should not. m4_text_wrap was using it, but in the Autoconf world
10548 where it is legal. Hence (i) test M4sh in its own world, not
10549 Autoconf's, and (ii), ahem, fix the bug :)
10551 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10552 does not like `' instead of [].
10553 (AT_INIT): Forbid `^_?AT_'.
10554 And don't output such tokens.
10555 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10556 `script.as', and `autom4te.cache'.
10557 Remove `empty' and `macro' which are no longer used.
10558 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10559 * tests/m4sugar.at: Use it.
10560 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10562 2001-08-07 Akim Demaille <akim@epita.fr>
10564 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10566 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10568 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10570 2001-08-04 Akim Demaille <akim@epita.fr>
10572 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10573 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10574 AC_TRY_LINK.
10575 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10576 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10577 (AC_F77_MAIN): Likewise.
10579 2001-08-04 Akim Demaille <akim@epita.fr>
10581 Don't rely on M4sugar outputting the patterns in files, since we
10582 might process the output _without_ running m4, hence without these
10583 files.
10585 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10586 * bin/autom4te.in (@Request::includes): Remove, unused.
10587 (@Request::source): Rename as...
10588 (@Request::input): this.
10589 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10590 (&handle_output): Fetch the patterns from the traces.
10591 `$forbidden' and `$allowed' are constant: use m//o.
10592 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10593 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
10595 2001-08-04 Akim Demaille <akim@epita.fr>
10597 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10598 autoconf', i.e., in addition to caching traces, cache the output.
10600 * bin/autom4te.in (Request::cache): Rename as...
10601 (Request::id): this.
10602 ($cache, $icache, $tcache, $ocache): New.
10603 (&handle_m4): Save M4 output in the cache instead of $tmp.
10604 (&handle_output): Adjust.
10605 (&up_to_date_p): Check that the output cache is up to date too.
10606 (top level): Run `&handle_m4' iff force or the cache is invalid.
10607 Run `&handle_output' if the output cache is more recent.
10609 2001-08-04 Akim Demaille <akim@epita.fr>
10611 * bin/autom4te.in ($force): New.
10612 (&parse_args, &print_usage): -f, --force is a new option.
10613 (&handle_output): CPP directives might have spaces after `#'.
10614 (&parse_args): The first file only can be frozen.
10616 2001-08-04 Akim Demaille <akim@epita.fr>
10618 Don't let autom4te compute the `include' traces several times:
10619 first check that the trace cache file is up to date, and then
10620 compare its timestamp with that of the output.
10622 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
10623 the preamble. Don't require 5.005 as Autom4te::General does it,
10624 and better yet (use `use', not `require'!).
10625 * lib/Autom4te/Struct.pm: Rename the last occurrences of
10626 Class::Struct as Autom4te::Struct.
10627 * lib/Autom4te/General.pm (File::stat): Use it.
10628 (&mtime): New, export it.
10629 * bin/autom4te.in: Use it.
10630 Declare `$req' is invalid if it is outdated.
10631 Don't declare it valid before saving it if something went wrong.
10633 2001-08-04 Akim Demaille <akim@epita.fr>
10635 Autom4te shall not encode Autoconf data, and preselecting traces
10636 must be proposed to the users.
10638 * bin/autom4te.in (@required_trace): Remove.
10639 (@preselect): New.
10640 (&parse_args, &print_usage): -p, --preselect is a new option.
10641 (&up_to_date_p): Adjust.
10642 * bin/autoconf.in: Preselect some Autoconf macros.
10644 2001-08-04 Akim Demaille <akim@epita.fr>
10646 * tests/tools.at (autoconf --trace: user macros): Check traces on
10647 macros invoked without arguments, and macros invoked with multiple
10648 lines arguments.
10650 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
10652 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
10653 arguments.
10655 2001-08-03 Akim Demaille <akim@epita.fr>
10657 * bin/autoconf.in ($@): Work around the usual sh bug.
10658 From Nicolas Joly.
10660 2001-08-03 Akim Demaille <akim@epita.fr>
10662 Clean up the handling of the M4 builtins tracing exception.
10664 * bin/autom4te.in (Request::request): Don't complete M4 builtins
10665 trace requests.

10669 (&parse_args): Complete the trace requests with alternate names.
10670 (&handle_traces): Hence no longer do it here.
10671 (&trace_requests): Remove, unused.

10675 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
10676 m4_if, and m4_wrap.
10678 2001-08-03 Akim Demaille <akim@epita.fr>
10680 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
10681 (m4_divert_pop): Dump the whole diversion stack when a diversion
10682 mismatch happens.
10683 * bin/autom4te.in (&handle_output): Remember of the first
10684 occurrence of a possibly undefined macro, not the last.
10685 Complain about the possibly undefined macros in the same order as
10686 the appear in the output.
10687 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
10688 * tests/tools.at (autoconf: forbidden tokens, basic)
10689 (autoconf: forbidden tokens, exceptions): No longer sort
10690 autoconf's stderr, as it is now deterministic.
10691 Check that `dnl' is caught.
10693 2001-08-01 Akim Demaille <akim@epita.fr>
10695 * configure.ac: Bump to 2.52c.

10709 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
10710 `die'.
10711 (&END): New.
10712 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
10713 `END', as `Autom4te::General::END' will be triggered.

11107 compiler, not the preprocessor.

11150 cross-language link tests can be performed successfully.
11151 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
11152 after $LIBS, for consistency; this should be the general rule since

11156 2001-06-29 Pavel Roskin <proski@gnu.org>

11159 at-stdout and at-stderr instead of removing the newline
11160 from the echo output, which is not guaranteed to work.
11162 2001-06-28 Jens Petersen <petersen@redhat.com>
11164 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to
