1 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
4 Fix typos.
6 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
7 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
8 not defined.
9 * doc/autoconf.texi (Changed Directory Variables): New node,
10 to document the whole `datarootdir' business a bit better.
11 * NEWS: Update.
12 * tests/torture.at (datarootdir workaround): Extend test.
13 Prompted by report by Alexandre Julliard.
15 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
17 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
18 when using default mode of IBM C 6 for AIX. Problem and two-line
19 fix reported by Larry Jones.
21 2006-06-22 Alexandre Julliard <julliard@winehq.org>
23 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
24 about literal '${datarootdir}' if a definition is found in the
25 output file.
27 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
29 * NEWS: Use "M4" rather than "m4" when appropriate.
30 Problem reported by Eric Blake.
31 * doc/autoconf.texi: Likewise.
32 Use @acronym around BSD, GCC, and GNU when appropriate.
33 (Why GNU M4): Renamed from "Why GNU m4".
34 (Redefined M4 Macros): Mention that Posix
35 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
36 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
37 to int.
39 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
41 * bin/autom4te.in (handle_output): Do not forbid the empty
42 pattern.
43 * tests/tools.at (autoconf: the empty token): New test.
45 2006-06-20 Stepan Kasal <kasal@ucw.cz>
47 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
48 calls, so that we do not care whether they are LIFO or FIFO;
49 in the m4_wrap, do not check which diversion is the topmost
50 one, just check that the stack is balanced at the end.
51 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
52 base diversion forever--pop the previous diversion before
53 opening the new one; consequently, remove the m4_wrap call.
54 * lib/autotest/general.m4 (AT_INIT): Likewise.
55 * tests/m4sugar.at: Do not use
56 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
58 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
59 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
61 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
62 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
63 Rework example of m4wrap token-pasting trouble so that it doesn't
64 care whether it's LIFO or FIFO.
65 Fix some "contrary to"s that are awkward in English.
67 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
69 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
70 to `yes' instead of `int$1_t' if the type is found, for more
71 consistent configure output (where $1 is the number of bits).
72 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
73 Suggested by Bruno Haible.
75 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
76 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
77 with system headers. Report by Bruno Haible.
79 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
81 * config/config.guess, config/config.sub: Sync from upstream.
83 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
84 in order to avoid picking up an older installed frozen m4sh.m4f.
85 Besides an outdated shell startup, this could have been created
86 by an earlier M4 version with incompatible frozen file format.
88 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
90 * README: Recommend m4 1.4.4 instead of 1.4.3..
91 * doc/autoconf.texi: Likewise.
92 (Special Chars in Names): Say that $(.FOO) is portable, as
93 suggested by Stepan Kasal.
94 (Installation Directory Variables, Build Directories):
95 (Automatic Remaking, Subdirectories, Fortran Compiler):
96 (Making testsuite Scripts, Defining Directories):
97 Quote variable usages better.
98 (Making testsuite Scripts): Add clean-local rule to makefile
99 snippet, by Eric Blake.
100 (Installation Directory Variables): Fix table item font.
101 Reword slightly to clarify. Generalize advice about
102 not using special characters to include all file-related
103 vars, not just VPATH.
104 (Special Chars in Variables): Warn about special characters in
105 $(srcdir) too.
106 (Assignments): Clarify default-value example as suggested by
107 Ralf Wildenhues in
108 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
109 (Special Shell Variables): Note leading ./ or ../, as suggested
110 by Eric Blake.
111 (Limitations of Builtins): Under cd, warn about CDPATH.
112 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
113 Ralf Wildenhues.
115 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
117 * doc/autoconf.texi (Configuration Actions): Remove duplicate
118 `@var', for texi2html.
119 (Systemology): Some more word wrapping, for DVI output.
120 (autom4te Invocation): The short option for `--melt' is `-M',
121 not `-m'.
123 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
125 * doc/autoconf.texi: More formatting and English tweaks,
126 many suggested by Ralf Wildenhues.
127 Reword to avoid "@code{...}'s" and the like, since it's ugly
128 with Emacs info mode. discontents -> woes.
129 Put a few "will"s back. time stamp -> timestamp.
130 side-effect -> side effect.
132 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
134 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
135 Warn about $@ not persisting. Problem reported by Julien Danjou in
136 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
137 (Special Chars in Names): Renamed from Leading _ in Macro Names.
138 Mention other special chars, too.
140 2006-06-14 Eric Blake <ebb9@byu.net>
142 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
144 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
146 * doc/autoconf.texi: Some systematic minor improvements, as
147 follows. Use "makefile" when talking about makefiles
148 generally (which might be named "makefile" or "Makefile" or even
149 "foo.mk"), "Makefile" when talking about a specific makefile
150 called "Makefile". This unclutters the text from weird quotes
151 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
152 values" rather than "@var{foo}s" and similar constructs containing
153 "}s". Use "Make rules" rather than "Makefile rules". Minor
154 English-language improvements. Change the prefix "sub-" to "sub"
155 and "re-" to "re".
156 Put blank lines around examples more consistently.
157 Avoid "rather" and "very" as intensifiers.
158 Avoid "will" as an auxiliary.
159 (Limitations of Make): Split this node into....
160 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
161 (Leading _ in Macro Names, Backslash-Newline-Newline):
162 (Backslash-Newline Comments, Long Lines in Makefiles):
163 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
164 (obj/ and Make, make -k Status, VPATH and Make):
165 (VPATH and Double-colon, $< in Explicit Rules):
166 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
167 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
168 New nodes, resulting from splitup of Limitations of Make.
169 All cross-references changed. Raise the top node from
170 a section to a chapter, and all subnodes accordingly.
171 Redo the introductory wording to match the new organization.
172 (Installation Directory Variables): Use an example that is
173 closer to what Autoconf actually does. Mention that VPATH's
174 value should not contain metacharacters or white space.
175 (Fortran Compiler): Fix a VPATH bug in an example.
176 (Leading _ in Macro Names): Mention that this problem is no longer
177 of practical concern.
178 (VPATH and Make): Reword the advice to make it clearer
179 that Autoconf and Automake support VPATH in non-GNU make, but
180 many packages have bugs in this area.
181 ($< in Explicit Rules): Refer to Build Directories rather
182 than using a (non-VPATH-safe) example.
183 (Automatic Rule Rewriting): Mention the sort of disaster that
184 can ensue with Solaris-style rule rewriting with VPATH.
186 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
188 * doc/install.texi (Compilers and Options): Weaken the
189 suggestion to use GNU make for VPATH builds.
191 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
192 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
194 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
195 in regular expression.
197 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
199 * doc/autoconf.texi (Installation Directory Variables):
200 Drop extra @samp from `@table @samp' item.
201 (Limitations of Usual Tools): Comment fix.
202 Do not nest @samp just to point to other table items.
203 (Writing testsuite.at) <AT_CHECK>: The second argument to
204 `@dvar' is already @samp'ed.
205 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
206 do not use @var in the second argument.
208 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
210 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
211 $as_shell.exe too. Problem reported by Andreas Buening in
212 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
214 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
216 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
217 `unused variable' compiler warning, for `-Wall -Werror'.
218 Reported by Jaap Haitsma in
219 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
221 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
223 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
224 case the compiler dumps core. Problem reported for
225 OpenServer 5.0.7 by Tim Rice in
226 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
227 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
228 Likewise.
230 2006-06-06 Tim Rice <tim@multitalents.net>.
232 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
233 "ERROR" only shows up in "make check" output if there is an
234 error.
236 2006-06-06 Eric Blake <ebb9@byu.net>
238 * tests/tools.at (automatically allowed tokens): Fix typo.
240 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
242 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
244 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
245 typically overflows on x86 CPUs, even though the C standard
246 requires otherwise.
248 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
250 * configure.ac (AC_INIT): Bump to 2.59e.
251 * NEWS: Update.
253 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
255 Version 2.59d.
257 * config/texinfo.tex: Sync from upstream.
259 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
260 seen, invoke libtoolize with `--ltdl' argument.
261 * lib/autom4te.in (Autoreconf-preselections): Adjust.
262 * NEWS: Update.
263 Suggested by Eric Blake.
265 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
267 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
268 reported by Ralf Wildenhues.
269 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
271 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
273 * THANKS: Update.
275 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

282 message issued by AC_REQUIRE.
283 * tests/m4sugar.at: Check m4_require's error message.
284 * tests/base.at: Check AC_REQUIRE's error message.
285 * tests/local.at (AT_CHECK_M4): New macro, almost identical
286 to...
287 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
288 AT_CHECK_M4.
289 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
290 `expout' as the last parameter.
291 * tests/tools.at: Adapt to the above change.
293 2006-06-04 Stepan Kasal <kasal@ucw.cz>
295 * doc/autoconf.texi (Limitations of Usual Tools): Correct
296 information about race-free implementations of mkdir.
298 2006-06-04 Eric Blake <ebb9@byu.net>
300 * bin/autoreconf.in (help): Document M4 environment variable.
301 * bin/autoconf.as (Usage): Likewise.
302 * bin/autom4te.in (help): Likewise.
303 * doc/autoconf.texi (autom4te Invocation): Likewise.
305 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
307 * NEWS: GNU make now recommended for VPATH builds.
308 Mention that some macros are now documented to be obsolescent.
309 * doc/autoconf.texi:
310 Prefer "current" to "modern" to describe
311 currently-used (albeit perhaps old-fashioned) hosts.
312 Mention which ancient features no longer need to be worried about.
313 setgid -> set-group-ID
314 setuid -> set-user-ID (these are the Posix terms)
315 Fix some misuses of "only".
316 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
317 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
318 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
319 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
320 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
321 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
322 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
323 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
324 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
325 Mention that these macros are obsolescent.
326 (Installation Directory Variables): shall -> should
327 (File Descriptors): Mention that 0, 1, 2 might get reopened.
328 Mention that it's now safe to use 3 and 4.
329 (Limitations of Usual Tools): cp -r is now specified by Posix.
330 Omit longwinded and obsolescent discussion of cp -f.
331 Modernize discussion of expr, ls.
332 (Limitations of Make): Modernize discussion of VPATH builds.
333 Mention $? as a workaround in some cases.
334 * doc/install.texi (Basic Installation):
335 Mention "./configure; make; make install" first. Be more
336 specific about why this file is generic. Remove unnecessary
337 parens. Remove misleading "only". Remove obsolete advice
338 about csh. Don't say "configure" takes awhile; say it
339 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
340 and CC=c99 rather than CC=c89, as these are blessed by current
341 Posix. Recommend GNU make if doing a VPATH build.
343 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
345 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
346 examples involving shell prompts.
348 2006-06-02 Stepan Kasal <kasal@ucw.cz>
349 and Paul Eggert <eggert@cs.ucla.edu>
351 * doc/autoconf.texi (Here-Documents): Add details about the
352 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
353 use "here-documents" instead of "here documents".
355 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
357 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
359 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
361 * doc/autoconf.texi (File System Conventions): Warn about ":"
362 anywhere in directory names.
364 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
366 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
367 about quoting the case statement, just in case.
368 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
369 was fixed in ksh93g; reported by Ralf Wildenhues.
371 2006-05-31 Stepan Kasal <kasal@ucw.cz>
373 * doc/autoconf.texi (System Services): Do not document
374 overriding EXEEXT via ac_cv_exeext=ext.
375 (Particular Programs) <AC_PROG_MKDIR_P>:
376 Document that ${MKDIR_P} understands --.
377 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
378 comment.
380 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
382 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
383 argument with leading hyphen. Problem reported by Paul Eggert.
385 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
387 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
388 about quoting ac_try: quote all of it, if any of it seems suspicious.
389 This means we don't have to worry about ${ or sed any more.
390 Also, double-quote the case statement, to work around misuses via
391 underquoting as reported by Ralf Wildenhues in
392 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
393 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
394 undocumented and dangerous macro.
395 Problem reported by Ralf Wildenhues in
396 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
398 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
400 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
401 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
402 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
404 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
406 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
407 since evidently some packages rely on the old, broken behavior.
408 Problem reported by Ralf Wildenhues in
409 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
410 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
411 pre-2006-05-26 definitions, but leave in the comments that
412 these macros are dangerous and should not be used.
413 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
414 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
415 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
416 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
417 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
419 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
421 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
422 the use of 'tr', since this is our only use of 'tr'.
424 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
425 and Paul Eggert <eggert@cs.ucla.edu>
427 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
428 Don't assume 'grep' works on long lines, since AIX grep doesn't.
430 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
432 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
433 the output file in the `${datarootdir}' test.
435 2005-05-28 Stepan Kasal <kasal@ucw.cz>
436 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
438 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
439 mention of `datarootdir' in the input file(s), but literal
440 `${datarootdir}' in the output file, and we haven't warned yet,
441 then warn as well: the user may have (erroneously) used
442 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
443 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
444 * tests/torture.at (datarootdir workaround): Extend this test.
445 * NEWS: Update.
447 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
448 and Paul Eggert <eggert@cs.ucla.edu>
450 * doc/autoconf.texi (autoheader Invocation): The first argument to
451 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
452 alternatives and clear up the language a bit.
454 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
456 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
457 ac_config_guess, ac_config_sub, ac_configure.
458 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
459 Fix typo that prevented an unnecessary space from being removed.
460 Problems reported by Ralf Wildenhues in:
461 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
463 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
465 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
466 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
467 Don't use the term "thread-safe" to talk about mkdir race
468 conditions, since the problem is more a process than a thread
469 issue. Problem reported by Stepan Kasal in:
470 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
471 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
472 the test for 'install' more closely. Look at MKDIR_P first.
473 Look in the PATH, and at /opt/sfw/bin.
474 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
475 Don't bother to try mkdir -p, since we already check mkdir --version;
476 just look at the version number. (There's no easy way to check
477 for race-free implementations.)
478 * tests/tools.at (autoconf: subdirectories): Adjust to above
479 changes, since MKDIR_P now might end in "/mkdir -p".
481 * doc/autoconf.texi (autoheader Invocation): Mention that the
482 first arg of AC_DEFINE_UNQUOTED must be a literal.
483 Problem reported by Ben Pfaff in
484 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
486 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
487 * doc/autoconf.texi (Special Chars in Variables): New section.
488 (Preset Output Variables): Warn about special chars in CPPFLAGS.
489 (Installation Directory Variables): Quote $(datadir) better.
490 (Limitations of Builtins): Describe some of eval's trickiness.
492 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
493 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
494 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
495 in front of every arg, not just trailing args. Quote apostrophes.
496 (_AC_EVAL_ECHO): New macro.
497 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
498 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
499 removed.
500 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
501 exposed by quoting of eval argument. Put the command on line line
502 so it logs better.
503 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
504 (_AC_PATH_X, AC_PATH_X): Quote more safely.
505 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
506 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
507 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
508 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
509 Use eval more safely.
510 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
511 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
512 to be replaced.
513 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
514 lines, exposed by quoting of eval argument.
516 2006-05-26 Stepan Kasal <kasal@ucw.cz>
517 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
519 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
520 initialization of `ac_cv_exeext', do not override it if it was
521 already set, unless it was set to `no', for compatibility with
522 Autoconf-2.13, and comment this.
523 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
524 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
525 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
526 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
527 Document that this test may be overridden by setting
528 `ac_cv_exeext'.
530 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
532 Revert these two patches:
534 2006-04-06 Eric Blake <ebb9@byu.net>
535 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
536 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
537 2006-04-01.
539 2006-04-01 Stepan Kasal <kasal@ucw.cz>
540 Clean up _AC_COMPILER_EXEEXT* macros.
541 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
542 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
543 ac_file to the name of the default output file and call
544 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
545 initial `rm' of the candidate files...
546 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
547 the same list in subsequent `rm' calls, and for the temporary
548 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
549 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
550 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
551 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
552 no longer needed) by libtool. Make it a cache check.
553 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
554 copied here by mistake.
555 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
556 _AC_COMPILER_EXEEXT.
557 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
558 _AC_COMPILER_OBJEXT directly.
559 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
561 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
563 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
564 Fix description of how the buggy `sed' works.
566 2006-05-25 Noah Misch <noah@cs.caltech.edu>
568 Sync from Automake:
570 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
571 ENOLCK. Only mention `make -j' when applicable. Only raise
572 fatal errors when `make -j' is involved. Improve error message.
574 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
576 * doc/autoconf.texi (Here-Documents): We now know more about
577 the variable expansion in here documents bug.
578 Thanks to Tim Rice and Stepan Kasal.
580 * doc/autoconf.texi (Making testsuite Scripts): Add an example
581 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
583 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
585 * tests/autotest.at (Multiline command from M4 expansion):
586 No failure to be expected if the shell quotes newlines in
587 commands in the `set -x' output. Report by Tim Rice.
588 * THANKS: Update.
590 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
592 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
593 expansion in the here-documents used by config.status, as that
594 runs afoul of the Korn shell version M-12/28/93d bug described in
595 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
596 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
597 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
599 2006-05-23 Jim Meyering <jim@meyering.net>
601 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
602 Fix typo introduced with 2006-04-02 change. It reversed the sense
603 of the test.
605 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
607 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
608 ac_dB slightly, to save bytes in the script.
609 Max out at 50 lines, rather than 96; this is more likely
610 (though not guaranteed) to avoid obscure 'sed' failures.
612 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
614 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
615 `tr -d -' as bad option argument. Work around this by deleting
616 an unrelated character.
617 Report by Tim Rice <tim@multitalents.net>.
619 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
620 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
621 Stepan Kasal <kasal@ucw.cz>
623 * doc/autoconf.texi (Particular Programs): Do not promise that
624 we always prefer the GNU version of the program, and that we
625 search according to PATH; both rules can have exceptions.
626 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
627 AC_PROG_SED. Move descriptions of limitations
628 to the Limitations of Usual Tools section.
629 (Limitations of Usual Tools) <sed>: Mention script length
630 limitations with Solaris /usr/ucb/sed.
631 <grep>: Fix wording for empty alternative. Mention that -c and
632 -l should not be combined, and that -E and -F should not be
633 combined.
635 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
636 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
638 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
639 limits in Solaris 8 /usr/ucb/sed by testing a long script.
641 2006-05-22 Stepan Kasal <kasal@ucw.cz>
643 * doc/autoconf.texi (Defining Symbols): Literal parameter of
644 AC_DEFINE is now passed to m4_pattern_allow.
645 * NEWS: Mention that; likewise for AC_SUBST.
646 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
647 the parameter to m4_pattern_allow.
648 * tests/tools.at: Add a check for that.
650 2006-05-22 Stepan Kasal <kasal@ucw.cz>
652 * lib/autoconf/status.m4: Fix typos.
654 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
656 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
657 only the files that this macro generates.
659 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
661 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
662 the HP-UX sed limitation of 99 commands, labels do not count.
663 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
664 in the comment.
665 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
667 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
669 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
670 Import the following fix from coreutils:
672 2006-01-13 Jim Meyering <jim@meyering.net>
674 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
675 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
676 not double-quote uses of that variable, to accommodate the rare
677 case in which getmntent is available in none of the libraries
678 checked. This happens at least on FreeBSD 5.0.
680 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
682 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
683 ac_config_guess, ac_config_sub, and ac_configure, since evidently
684 some other programs unwisely rely on these undocumented vars.
685 But put in warning comments about them.
686 Problem reported by Ralf Wildenhues in
687 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
688 * NEWS: Document that these variables are intended to go away.
690 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
692 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
693 and set the language to C++ (analogous to the equivalent Fortran
694 tests).
696 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
697 * doc/autoconf.texi (C++ Compiler): Document it.
698 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
699 * NEWS: Update.
701 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
703 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
704 that caused config.status to generate 100-command sed scripts; the
705 portable limit is 99.
707 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
709 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
710 variable `ac_d' instead of `d' to avoid infringing namespace.
711 Report by Ralf Menzel.
713 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
715 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
716 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
717 * tests/tools.at (autoconf: subdirectories): New test, taken from
718 the corresponding problem report by Ralf Wildenhues in:
719 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
721 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
722 Quote some uses of shell variables if they might suffer unexpected
723 globbing. This doesn't fix all instances of quoting problems that
724 I found, just the easy ones that look safe.
725 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
726 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
727 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
728 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
729 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
730 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
731 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
732 Likewise.
733 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
734 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
736 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
738 * bin/autoreconf.in ($help): Reword according to the manual.
739 Suggested by Olly Betts.
741 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
742 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
744 * bin/autoreconf.in: Pass the directory argument to
745 `require_configure_ac'. Fix comment.
746 * tests/torture.at (Configuring subdirectories): Expose this.
747 Reported by Olly Betts.
749 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
751 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
752 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
753 Automake as follows:
755 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
756 `$configure_in' instead of `configure.in', to preserve
757 directory component.
759 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
761 * config/config.guess, config/config.sub, config/texinfo.tex,
762 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
764 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
766 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
767 test for C99 conformance; (bool) 0.5 is an integer constant
768 expression, but (bool) -0.5 is not. Problem reported by Fedor
769 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
771 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
773 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
774 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
775 Warn about obsolete install-sh files. Remove stray sentence
776 fragment and fix cross reference.
777 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
778 install -d; this undoes the 2006-05-10 change.
779 (MKDIR_P): Mark with AN_MAKEVAR.
780 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
781 that we don't require $INSTALL to be thread-safe. Move comments
782 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
783 of AC_PROG_INSTALL. Output a message saying that we're checking
784 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
785 MKDIR_P instead of AC_SUBST.
786 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
787 Special magic for MKDIR_P, too.
788 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
789 a dnl.
790 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
792 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
794 Sync from Automake, as follows:
796 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
797 * config/install-sh: Initialize IFS, so field splitting isn't
798 turned off later.
799 * config/mkinstalldirs: Likewise.
800 * config/missing: Remove superfluous quotes. Replace all uses of
801 `[' by `test', for consistency, and for..
802 * config/missing (sed_minuso, sed_output): New variables.
803 (autom4te, help2man, makeinfo): Use them. Unifies detection of
804 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
805 Fixes `missing' to detect `--output' for help2man. Fixes
806 PR automake/483. Report by Dennis J. Linse.
807 (autom4te): Document in `missing --help'.
809 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
811 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
812 * config/install-sh: Don't use 'path' to talk about file names,
813 as per GNU coding standards. Close a race condition reported by Ralf
814 Wildenhues and Stepan Kasal. There is still a race condition
815 on hosts that predate Posix 1003.1-1992, but we can't help this.
816 Don't mishandle weird characters like space on pre-Posix hosts.
817 Invoke mkdir at most once per dir arg on pre-Posix hosts.
818 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
819 AC_PROG_MKDIR_P from AS_MKDIR_P.
820 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
821 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
822 earlier editions are not (including Automake 1.8.3).
823 Do not suggest mkinstalldirs for thread-safety.
824 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
825 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
826 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
827 presence of special characters and race conditions.
828 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
829 in Autoconf's name space.
831 2006-05-10 Bruno Haible <bruno@clisp.org>
832 and Paul Eggert <eggert@cs.ucla.edu>
834 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
835 from Automake with minor changes.
836 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
838 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
840 * config/install-sh: Update to Automake CVS version, as follows:
841 2006-04-25 Stepan Kasal <kasal@ucw.cz>
842 * lib/install-sh: Simplify the expr implementation of dirname.
843 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
844 * lib/install-sh: Handle --, and diagnose unknown options.
846 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
848 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
849 `./autom4te' to create `./testsuite', since the `all' target
850 will ensure its presence, but `installcheck' should not create
851 the uninstalled wrappers.
853 * tests/torture.at (Unusual Automake input files): Skip if we
854 detect automake < 1.8.
856 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
858 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
859 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
860 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
861 * NEWS: Update.
863 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
865 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
866 munge (multiple) white space and other oddities.
867 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
868 single quotes in variable assignment.
869 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
870 and similar failures by adding multiple spaces, tabs, and other
871 special characters.
872 Report and different test suggested by Francesco Romani
873 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
875 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
876 single quotes, we only need to search for single quotes; this
877 both simplifies the search pattern, and makes us less
878 susceptible to `echo' variations for arguments not containing
879 single quotes.
880 (_AC_ARG_VAR_VALIDATE): Likewise.
882 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
884 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
885 `$*' and IFS concatenation issue with traditional shells and
886 bash-2.04. Report by Seanster@Seanster.com.
888 2006-05-03 Bruno Haible <bruno@clisp.org>
890 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
891 precisely which Mac OS X versions have the od problem.
893 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
895 * doc/autoconf.texi: Use @option systematically.
897 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
898 and Bruno Haible <bruno@clisp.org>
900 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
901 about 'od'.
902 (Integer Overflow): Mention the special case of integer division
903 overflow.
905 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
907 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
908 traditional shells like the Solaris one that do not use the
909 first IFS character for assembling `$*'.
910 Prompted by a related report from autoconf_bug@nro.ca.
912 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
913 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

966 * bin/autoconf.as (me): Replace by as_me.
968 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
970 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
971 since as_me isn't set yet.
973 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
975 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
976 a few minor bugs in this area.
978 * doc/autoconf.texi (Programming in M4sh): Comment out the
979 documentation of AS_BASENAME, for now.
980 (Shell Substitutions): Do not use AS_DIRNAME in an example.
981 (Limitations of Builtins) <basename>: Do not refer to
982 AS_BASENAME.
983 * bin/autoconf.as (me): Don't use AS_BASENAME.

1005 * lib/autoconf/general.m4: Likewise.
1006 * lib/autoconf/headers.m4: Likewise.
1008 * doc/autoconf.texi (Run Time): Document the exit status situation
1009 with more accuracy and detail.
1011 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1013 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1014 Archive is not officially `GNU' any more. Update URL.
1015 (Defining Directories): Likewise
1016 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1018 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1020 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1021 newline from the `trap' code to finish `config.log'; the NetBSD
1022 /bin/sh resets the exit status after an empty command, as
1023 documented in doc/autoconf.texi.
1024 Reported by Dalibor Topic <robilad@kaffe.org>.
1026 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1028 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1029 Suggested by Bruno Haible.
1031 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1033 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1034 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1035 Instead, just list the shells that we know work.
1036 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1037 changed. Be more cautious about the _cv_ variable.
1038 * tests/tools.at (Syntax of the shell scripts): Check the
1039 _cv_ variable once, at first, to avoid an internal autoconf error
1040 when sh -n does not work.
1042 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1044 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1046 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1048 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1049 use ">&-" since we're only 99.999% sure that this is portable,
1050 and since the MinGW bug is fixed in a different way.
1051 * lib/autotest/general.m4 (AT_INIT): Likewise.
1053 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1055 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1056 before opening config.log, to avoid hitting a bug on MinGW.
1058 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1060 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1061 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1062 This works around a MinGW bug reported by Eric Paire.
1063 Make sure that all writes to the log file append to it,
1064 rather than possibly losing data.
1065 * lib/autotest/general.m4 (AT_INIT): Likewise.
1067 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1069 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1070 description.
1072 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1074 * NEWS: Update.
1076 * configure.ac (AC_INIT): Bump to 2.59d.
1078 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1080 Version 2.59c.
1082 * Makefile.maint (news-date-check): Do not require a leading `*'
1083 before the release date in NEWS.
1085 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1086 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1088 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1089 the instantiated file do not contain the string 'datarootdir'
1090 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1091 @mandir@, replace the reference '${datarootdir}' by the value.
1092 * tests/torture.at (datarootdir workaround): New test.
1093 * NEWS: Advertise this temporary fixup.
1094 Based on a patch by Bruno Haible, reported and analyzed by
1095 Paul Eggert and Noah Misch.
1097 2006-04-12 Eric Blake <ebb9@byu.net>
1099 * tests/autotest.at (Debugging a failed test): Fix comment.
1101 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1103 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1104 all the changes since 2006-04-07.
1106 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1108 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1109 succeeded, but `ln -s file dir' failed, take care to remove the
1110 leftover target before the next test, to prevent its spurious
1111 failure; also make sure `ln file dir' works before selecting it.
1112 Thanks to Keith Marshall for pointing this out.
1113 * THANKS: Update.
1115 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1116 assignments in `at_debug_args', so that we put them correctly
1117 in the `run' script.
1118 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1119 Reported by Eric Blake.
1121 2006-04-11 Eric Blake <ebb9@byu.net>
1123 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1124 top-level tests after micro-suite has been run. Used in...
1125 (Debugging a successful test, Debugging script and environment),
1126 (Debugging a failed test): ...these new tests. The first of these
1127 is fixed by...
1128 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1129 macro, split out from...
1130 (AT_INIT): ...here, so that using -d also generates a run script.
1131 Document that -d inhibits top-level logging.
1132 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1133 inhibits top-level logging; debug scripts are created.
1135 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1136 check.
1137 * tests/autotest.at (Empty test, Empty check): New test to check it.
1139 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1140 from gcc.
1142 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1144 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1145 the files if a problem appears. Make the empty *.at files
1146 read-only, too. Proposed by Ralf Wildenhues.
1148 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1150 * config/Makefile.am: Add comment to force updated Makefile.in.
1152 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1153 space only patch to this file, this patch causes the Makefile.in
1154 files that include freeze.mk to be updated, and thus have a
1155 newer time stamp again, which in turn makes a pristine CVS
1156 checkout have correct time stamps.
1158 * Makefile.maint (cvs-sv): New macro, to be used..
1159 (config.guess-url_prefix, config.sub-url_prefix)
1160 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1161 point to CVS text checkout of Gnulib files.
1162 (copyright-check): Bump current year.
1163 (announcement): Do not hard-wire `./announce-gen'.
1164 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1165 correctly.
1166 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1167 `chmod +x'.
1168 (wget_files): Update config.guess, config.sub, texinfo.tex by
1169 `wget-update', now that their URLs work again.
1171 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1173 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1174 Problem noted by Paul D. Smith.
1176 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1178 * doc/autoconf.texi: Remove unused words from word list.
1179 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1180 .x-sc_trailing_space: New files.
1182 * doc/standards.texi: Sync from gnulib.
1184 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1185 `LIBOBJDIR' as experimental.
1187 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1188 with a target directory; it's internally implemented as `cp'
1189 anyway, but since Autoconf advertises the possibility to use
1190 a target directory when LN_S is `ln -s', we need to find out.
1191 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1192 analyzed by Keith Marshall <keith.marshall@total.com>.
1194 * THANKS: Update.
1196 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1198 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1199 confdefs.h as-is. In general, if it has backslash-newline or the
1200 like, then it doesn't work either to sort or to remove empty
1201 lines.
1203 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1205 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1207 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1209 * lib/autom4te.in (Automake-preselections): Preselect
1210 _AM_SUBST_NOTMAKE.
1212 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1214 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1215 apostrophe within a single-quoted string, as this is the usual
1216 tradition and is easier to read than '"'"'. Don't rely on the
1217 shell treating "$/" like '$/'. Use a more-consistent indenting
1218 style for the trap.
1220 2006-04-09 Eric Blake <ebb9@byu.net>
1222 * tests/autotest.at (Backquote command substitution),
1223 (Multiline backquote command substitution): Remove mistaken
1224 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1225 applied...
1226 (Parenthetical command substitution, Multiline parenthetical
1227 command substitution): here.
1229 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1231 Import macros from gnulib (often changing their name).

1245 (Pointers): Add Gnulib URL.
1246 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
1247 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
1248 Gnulib section.
1249 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
1250 suggest a #define rather than a typedef for _Bool, and mention
1251 Gnulib rather than trying to substitute stdbool code.
1252 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
1253 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
1254 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
1255 AC_STRUCT_DIRENT_D_TYPE.
1256 (Particular Types): Mention stdint.h and inttypes.h as standard
1257 headers too.
1258 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
1259 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
1260 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
1261 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
1262 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1263 (C Compiler): Move AC_C_LONG_DOUBLE to ...
1264 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
1265 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
1266 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
1267 (Coding Style). Don't mention m4_expand_once.
1268 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
1269 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
1270 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
1271 (AC_CHECK_FUNCS): Use it.
1272 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
1273 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
1274 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
1275 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
1276 (AC_HEADER_ASSERT): New macro.
1277 (AC_HEADER_STDBOOL): Don't assume "#error" works.
1278 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
1279 Catch a bug in an HP-UX C compiler.
1280 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
1281 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
1282 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

1284 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
1285 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
1286 New macros.
1288 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
1289 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
1291 2006-04-08 Stepan Kasal <kasal@ucw.cz>
1293 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
1294 of the warning introduced by the 2001-08-28 change.
1296 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
1297 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1299 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
1300 variables shall be overriden by the cache.
1301 * tests/torture.at (AC_ARG_VAR): Test also with a first value
1302 that contains braces.
1304 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1306 Revert the patch from 2006-04-01 and only improve
1307 _AS_DETECT_BETTER_SHELL:
1309 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1310 skip nonexistent directories.
1311 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1312 only shell candidates which exist.
1313 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1314 * lib/autotest/general.m4 (AT_INIT): No need to give three
1315 parameters to _AS_PATH_WALK.
1317 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1318 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1320 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1321 distinguish m4sugar macros.
1322 * tests/tools.at (autoupdating with aclocal and m4_include):
1323 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1324 test case by Noah Misch <noah@cs.caltech.edu>.
1326 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1328 Revert my change from 2006-03-17, in other words:
1329 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1330 and DUALCASE=1.
1331 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1332 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1333 it is set.
1335 2006-04-07 Eric Blake <ebb9@byu.net>
1337 * doc/autoconf.texi (Programming in M4sh): Document that
1338 AS_MKDIR_P exits the script on failure.
1339 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1341 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1343 * config/elisp-comp, config/install-sh, config/mdate-sh,
1344 config/missing, config/mkinstalldirs: Sync from Automake.

1353 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1354 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1355 2006-04-01.
1357 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
1358 Eric Blake <ebb9@byu.net>,
1359 Paul Eggert <eggert@cs.ucla.edu>,
1360 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1362 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1363 whether `set' quotes correctly: redirect stderr of the tested
1364 `set', and use a subshell, for Ultrix; use `sed' instead of
1365 `grep' for zsh `set' which may write binary output; match only
1366 at the beginning of a line, to avoid false positives.
1367 In order to avoid false positives by unrelated variables with
1368 multiline content, put the dump algorithm in a subshell and
1369 unset all variables containing newlines (except some which are
1370 special to the shell). Warn about cache variables that are
1371 unset.
1373 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1378 * tests/mktests.sh: Reword comments.
1380 * tests/mktests.sh: Only skip internal macros starting with

1423 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1424 _AC_PRESERVE_HELP_ORDER, ...

1427 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1428 inside m4_expand_once; it is redundant.
1430 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
1431 for --help from Cygnus `configure.'
1433 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

1486 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
1487 Use 'comm' rather than N instances of grep; this also fixes a bug
1488 whereby substrings were incorrectly matched, causing us to not
1489 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
1490 (exclude_list): Exclude empty macros.
1491 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

1496 Switch from grep to awk syntax.
1497 (ac_exclude_script): Renamed from ac_exclude_egrep.

1574 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1575 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1576 ac_file to the name of the default output file and call
1577 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1578 initial `rm' of the candidate files...
1579 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1580 the same list in subsequent `rm' calls, and for the temporary
1581 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1582 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1583 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1584 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1585 no longer needed) by libtool. Make it a cache check.
1586 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1587 copied here by mistake.
1588 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1589 _AC_COMPILER_EXEEXT.
1590 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

1623 Autoconf version number despite a zero- or one-argument AC_INIT.
1625 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
1626 subordinate tools.
1627 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
1628 * doc/autoconf.texi (autoreconf Invocation): Document it.
1630 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

1662 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1664 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
1665 switch all of them on and of when necessary. Fixes the bug when

1716 * bin/autoscan.in: The value of find_configure_ac should be
1717 checked for existence, so we don't barf over a nonexisting
1718 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
1720 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2282 CONFIG_SHELL in the environment of the configure rerun.
2283 * doc/autoconf.texi (Here-Documents, config.status Invocation):
2284 Suggest passing CONFIG_SHELL absolute, and in the environment
2285 rather than as option.
2287 2005-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2289 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2290 Fix quoting of output line (triggered for many AC_SUBST_FILEs).
2291 Fix macro quoting. Fix output for n * 98 substituted variables.
2293 2005-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2295 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Initialize
2296 `tmp' to avoid file removal race.
2298 2005-11-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2300 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
2301 ac_clean_files and LIBOBJS.
2303 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2305 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
2306 Factor functionality to..
2307 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
2308 `AC_SUBST($1)' in the public version.
2309 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
2310 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
2311 ac_pt_* variables.
2313 2005-11-01 Stepan Kasal <kasal@ucw.cz>
2315 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
2316 filesystems.
2318 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2320 * NEWS: Move AH_HEADER mention to right place.
2322 2005-10-27 Stepan Kasal <kasal@ucw.cz>
2324 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
2325 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
2327 2005-10-25 Stepan Kasal <kasal@ucw.cz>
2329 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
2330 conftst2.$ac_objext.
2331 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
2333 2005-10-24 Stepan Kasal <kasal@ucw.cz>
2335 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
2336 conftest.o, to see whether the compiler really obeys; rm the object
2337 file before and after the test and register it with ac_clean_files.
2338 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
2340 2005-10-21 Stepan Kasal <kasal@ucw.cz>
2342 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
2343 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
2344 code so that the most common case requires less forks.
2346 2005-10-20 Stepan Kasal <kasal@ucw.cz>
2348 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
2349 not portable; thanks to Paul Eggert and Alexandre.
2351 * NEWS: Fix an old typo.
2353 2005-10-20 Jim Meyering <jim@meyering.net>
2355 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
2356 the latter'', in two places.
2358 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
2360 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
2361 AC_LANG_PROGRAM, fixing a typo. Don't give details about
2362 the inner workings of AC_LANG_FUNC_LINK_TRY.
2363 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2364 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2365 by the function rather than ignoring it.
2366 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2367 comparing its address. Intel's interprocedural optimization was
2368 outsmarting the old heuristic. Problem reported by
2369 Mikulas Patocka.
2371 2005-10-19 Stepan Kasal <kasal@ucw.cz>
2373 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
2375 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
2377 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
2378 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
2380 2005-10-04 Stepan Kasal <kasal@ucw.cz>
2382 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
2383 before removing it (chmod -R u+rwx); there are three instances of this.
2385 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2386 Stepan Kasal <kasal@ucw.cz>
2388 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2389 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2390 make its content writable before removing it. Remove an errorneous
2391 comment from the end, where the logs of the failed tests are copied
2392 to the main log file.
2394 2005-09-27 Stepan Kasal <kasal@ucw.cz>
2396 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
2397 in case the computer is too quick. Double quote the configure.ac
2398 snippets.
2400 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
2401 problems if the testsuite were running too fast.
2403 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2405 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2406 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2407 (which belong to Xt, not X itself). See Debian bug 327655.
2408 * NEWS: Mention this.
2410 2005-09-07 Stepan Kasal <kasal@ucw.cz>
2412 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
2414 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
2416 * config/move-if-change: Don't output "$2 is unchanged";
2417 suggested by Ben Elliston. Handle weird characters correctly.
2419 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2421 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2422 calls, so that the final expansion of this macro is shorter.
2423 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2424 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2425 the cleanup there. Use AS_VAR_* macros, to be more general.
2426 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2428 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2430 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
2432 2005-09-01 Stepan Kasal <kasal@ucw.cz>
2434 * doc/autoconf.texi (Configuration Headers): Add an index entry
2435 for AH_HEADER.
2437 2005-08-26 Pavel Roskin <proski@gnu.org>
2439 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
2440 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
2441 running xmkmf.
2443 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
2445 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2446 The previous patch didn't work, so try a better one.
2448 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2450 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2451 in the example. Reported by Bruno Haible.
2452 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2453 "if $undefined_var;" succeeds with my shell.
2455 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2456 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2457 but change the m4_divert_text to m4_divert_once.
2459 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2461 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2462 Work around bug in Solaris /usr/xpg4/bin/awk.
2463 The bug is present in at least Solaris 8 through 10.
2465 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2467 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2468 some evil values and relying on the fact that $* concatenates the
2469 parameters by the first character from IFS.
2471 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2472 Stepan Kasal <kasal@ucw.cz>
2474 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2475 first header appears, define AH_HEADER.
2476 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2477 Update limitations about when to call AC_CONFIG_HEADERS.
2478 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2479 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2480 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2481 ``Configuration Actions''; fix their index entries.
2483 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2484 options correctly. Process N-M as M-N if M is smaller than N.
2485 Process ranges correctly so that N-N will run only N.
2486 Sort and uniquify the tests that will be run. If there is more
2487 than one test, reinsert the banners for the tests.
2488 * tests/autotest.at (Keywords): Unmark XFAIL.
2490 2005-08-23 Stepan Kasal <kasal@ucw.cz>
2492 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
2493 before passing the macro name to AH_TEMPLATE.
2495 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2496 now opens log after option processing; in particular, --version
2497 and --help do not touch config.log.
2499 * Makefile.maint: Revert the change from 2005-08-12.
2501 2005-08-22 Stepan Kasal <kasal@ucw.cz>
2503 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
2504 common code to...
2505 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
2507 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2509 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
2510 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
2511 Language cleanup.
2513 * doc/autoconf.texi (Defining Symbols, Changed Results):
2514 Prepend to LIBS, not append, in examples.
2516 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2518 When building in place, set srcdir="."; suggested by Tim Van Holder.
2520 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2521 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2522 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2523 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
2524 does not mean "no --srcdir option".
2526 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2528 * tests/autoscan.at (autoscan): New file.
2529 * tests/suite.at: Use it.
2530 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
2531 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
2533 * tests/autotest.at (Keywords): Test keywords combinations.
2535 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2537 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2538 add "2>&1"; gzip 1.2.4 prints help on stderr.
2540 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2542 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2543 was pushdef'ed twice while popped only once. Push it only once.
2544 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2546 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2548 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
2549 prefixed by mere "===", not "configure: === ".
2551 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
2553 * Makefile.maint: Update from Bison.
2555 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2556 "<tab>" in comment, so that the point is understandable.
2558 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2560 Rewrite substantial part of lib/autoconf/status.m4.
2561 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2562 and CONFIG_COMMANDS are not processed in four separate loops.
2563 Instead, there is one main loop. This alows that the common code
2564 is expanded only once, thus config.status (and configure) is smaller.
2566 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2567 the AC_LIST_FILES and cousins macros are no longer used.
2569 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2570 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2571 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2572 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2573 contain the initialization, nor the for loop, nor the associated
2574 commands; all these go to ...
2575 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2576 _AC_OUTPUT_CONFIG_STATUS.
2577 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2578 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2579 (_AC_OUTPUT_FILE): The creation of the sed script ...
2580 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2581 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2582 _AC_OUTPUT_MAIN_LOOP.
2583 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2584 _AC_CONFIG_COMMANDS): Use ...
2585 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2586 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2587 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2588 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2589 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2590 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2591 ... new macros.
2592 (_AC_CONFIG_UNIQUE): Update.
2593 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2594 Replaced by this ...
2595 (_AC_LIST_TAGS): ... new common macro.
2596 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2597 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2598 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2599 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2600 this didn't belong to the `config commands' section.
2601 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2602 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2603 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2604 to the `config commands' section either.
2605 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2606 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2608 ... and many changes to the comments nearby.
2610 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2611 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2612 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2613 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2614 (#define header templates): The comment at the top of the generated
2615 header now includes the name(s) of the source file(s).
2617 Several unrelated small changes:
2619 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2620 parameter to AC_DIAGNOSE.
2621 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2622 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2623 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2624 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2625 with AU::AC_OUTPUT.
2626 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2627 in AC_OUTPUT doesn't double-quote it either.
2628 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2629 parameters.
2631 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2633 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2634 versions of Portland Group compiler produce single- and double-quoted
2635 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
2636 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
2638 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2640 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2641 This is a corrected version of yesterday's patch.
2643 2005-07-07 Stepan Kasal <kasal@ucw.cz>
2645 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
2646 path, too; insert a "===" to emphasize the line.
2648 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
2649 ac_cv_build_alias to ac_build_alias.
2650 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
2652 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2653 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2654 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2655 (AC_ARG_VAR): ... here.
2656 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
2657 target_alias.
2659 Keep a list of all precious variables and process them with one simple
2660 for loop, instead of expanding all commands, or, OTOH, complicated
2661 processing of output of "set".
2662 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
2663 variable names in new macro...
2664 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
2665 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
2666 a loop to assign all ac_env_* and ac_cv_env_* variables.
2667 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
2668 to INIT_PREPARE.
2669 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
2670 its value to shell variable ac_precious_vars and call
2671 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
2672 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
2673 _AC_ARG_VAR_VALIDATE.
2675 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
2676 and the AC_SUBSTs ...
2677 (AC_INIT): ... here.
2679 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
2680 the ac_subst_files section in config.log.
2682 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
2684 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

2688 * lib/autoconf/c.m4 (AC_C_TYPEOF): New macro.
2689 * tests/c.at (C keywords): Test AC_C_TYPEOF.
2691 Fix problems reported by Nicolas Joly.
2692 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
2693 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2694 They are generated by the Tru64 v5.1B shell.
2696 2005-07-05 Stepan Kasal <kasal@ucw.cz>
2698 Fix my changes from 2005-07-01; reported by Noah Misch.
2699 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
2700 description, the macro now accepts only a single tag.
2701 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
2703 Fix cases when the varsions of Autoconf and Autotest don't match.
2704 Reported by Noah Misch.
2705 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
2706 at_top_builddir, for compatibility with older autotest.
2707 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
2708 is not set, use at_top_builddir, for compatibility with older
2709 versions of autoconf.
2711 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2713 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
2714 Problem reported by Patrick Welche.
2716 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
2718 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
2719 sed substitution command, so that we allow | in program prefixes
2720 and program suffixes. (& is a problem anyway; we're not fixing
2721 that here.)
2722 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2723 configure_input, top_builddir, srcdir, etc.
2724 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2725 PATH_SEPARATOR in AUTOTEST_PATH.
2727 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
2729 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
2730 for loop over config.site files using `set', to allow
2731 directory names containing IFS characters.

2735 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
2736 directories with weird names. Apparently some people like living
2737 on the edge. However, improve the test that "pwd" actually does
2738 report a name for the working directory.
2739 * NEWS: Remove the claim that we test for funny chars in dir names.
2741 2005-07-01 Stepan Kasal <kasal@ucw.cz>

2753 about #include <config.h>.
2754 (Generic Functions): Mention the Gnulib project.
2755 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
2757 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
2758 document to output the default config_* lists to config.status.
2759 Don't recognize option --file, if the functionality is not there.
2760 Likewise for --header; moreover, recognize --he and --h as shortcuts
2761 for --help in that case.
2763 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2764 matches the order of execution. No code changed.

2783 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
2785 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
2786 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
2787 (AC_SUBST): Call it.
2788 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2789 the directory specific variables; but don't call it for configure_input.
2791 2005-06-28 Derek Price <derek@ximbiot.com>
2793 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2794 addition.
2796 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
2798 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
2799 directory have inherent problems with special characters like spaces,
2800 due to limitations in Make syntax. Problem reported by Alexandre
2801 Duret-Lutz.
2802 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

2815 from Justace Clutter.
2816 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
2817 variable into diagnostic. Make the diagnostic an error, not a warning,
2818 because we really don't support spaces and suchlike in dir names.
2819 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2820 Don't worry about backslashes in srcdir; it can't happen now.
2821 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
2822 Simplify ac_optarg handling.

2833 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
2834 that '\|' is not allowed in BREs; recommend using newline separated
2835 list of patterns instead of multiple -e options.
2837 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
2839 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

2843 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
2845 2005-06-21 Stepan Kasal <kasal@ucw.cz>
2847 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
2848 b, t, r, w commands require single space, while : cannot have any.
2849 (Special Shell Variables): Fix sed code this in the example.
2850 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2851 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
2853 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
2854 expand to the empty list. Don't use two pairs of m4_changequote,
2855 it's not necessary.
2857 2005-06-20 Derek Price <derek@ximbiot.com>
2859 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
2861 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
2863 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
2864 * doc/autoconf.texi:
2865 Don't mention Solaris versions so much, if a
2866 problem is common to all extant versions of Solaris. Say "SunOS
2867 4" instead of "SunOS" for SunOS 4.
2868 (awk): Mention more of the limitations of traditional Awk.
2869 (cat): Don't talk about cat -v.
2871 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
2873 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
2874 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
2875 but the implementation is entirely different and is designed
2876 to be compatible with glibc strverscmp.
2877 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
2879 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
2880 on Mac OS X 10.4 reported by Peter O'Gorman in:
2881 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
2882 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
2883 Use shell builtins rather than 'expr', to work around expr bug.
2885 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
2887 * doc/autoconf.texi: "filesystem" -> "file system".
2888 "behaviour" -> "behavior".

2890 * lib/autoconf/general.m4: Omit blank after ":" sed command,
2891 as per POSIX.
2892 * lib/m4sugar/m4sh.m4: Likewise.
2893 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
2894 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
2896 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
2897 (.x.1): Ignore the time stamp in the .TH line when deciding whether
2898 to update the man page. That way, we don't have to check in new
2899 man pages every month.
2901 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
2902 quotes and backslashes. Patch from Derek Price.

2907 AS_TR_SH.
2909 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
2911 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
2912 -u, since it outputs chatter if the input files are the same.
2913 Problem reported by Ralf Menzel.
2915 2005-06-08 Derek Price <derek@ximbiot.com>
2917 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
2918 renaming them since they are about to be redefined anyhow.
2920 2005-06-08 Derek Price <derek@ximbiot.com>
2922 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
2923 redefined M4 macros to this node. Document m4_include & m4_sinclude.
2924 Move m4_undefine to alphabetical order.
2926 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
2928 * README: Recommend GNU M4 1.4.3 or later.
2929 * doc/autoconf.texi (Introduction): Likewise.
2930 Reword to avoid some formatting glitches.
2931 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
2932 Clarify explanation of HP compiler bug.
2933 Redo example output tp match current CVS snapshot.
2934 Use @example.org in email addresses when the examples
2935 might get inadvertently cut-and-pasted into user code.
2936 Remove example of autom4te usage that doesn't seem to work now.
2937 Use modern AC_INIT (except when the example is meant to be
2938 shown with Autoconf 2.13).
2939 Update ksh info for Solaris 9 and later.
2940 KB -> kB.
2941 Modernize description of Automake versions a bit.
2942 Don't claim a future version of Autoconf is near.
2943 * doc/install.texi: Reword to avoid some formatting glitches.
2945 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2947 * doc/autoconf.texi: Add [] to examples, so that the manual
2948 follows its own advice about quoting better.
2949 Reword to avoid some formatting glitches.
2950 * doc/installt.exi: Reword to avoid some formatting glitches.
2952 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
2953 Tru64 ksh pattern matching bug. Reported against Libtool by
2954 Albert Chin <libtool@mlists.thewrittenword.com> and
2955 Nicolas Joly <njoly@pasteur.fr>.
2957 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2959 m4_cdr of one-member list was [[]] (one-member list containing an
2960 empty string) instead of [] (an empty list. Callers were skewed to
2961 match this misbehaviour. As a consequence of this:
2962 - m4_foreach([x], [], [foo]) expanded to `foo', while
2963 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
2964 This bug has been fixed:
2966 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
2967 expand to an empty string; print error msg if called without
2968 an argument list.
2969 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
2970 misbehaviour; handle [] and [[]] correctly.
2972 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2974 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

2976 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
2978 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
2980 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
2981 swallow records with more than 99 fields.
2982 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
2983 parse the long line.
2985 2005-06-04 Stepan Kasal <kasal@ucw.cz>
2987 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
2988 swallow literals longer than 399. Reported by Ralf Wildenhues.
2989 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
2990 to workaround this limitation.
2992 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
2994 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
2995 to gfortran, and make these the first two compiler names
2996 checked (following the general autoconf preference for gcc).
2998 2005-06-03 Stepan Kasal <kasal@ucw.cz>
3000 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3001 (DISTCLEANFILES): Remove $(check_SCRIPTS).
3002 (testsuite): Make sure autotest.m4f is up-to-date before using it.
3004 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
3006 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3007 expression of unbounded size when processing the --list
3008 option. This runs afoul of a limit of 399 bytes per regular
3009 expression on AIX. Problem reported by Ralf Wildenhues.
3011 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
3013 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
3014 * doc/autoconf.texi (Particular Headers): Reword example
3015 for multiline stdbool replacement.
3016 (Setting Output Variables): Reword text a bit. Don't
3017 give all the details about |#_!!_#|.
3018 Reword description of line replacement.
3020 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3022 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3023 now contain newlines, and substituted files must be referenced on
3024 a line alone; the sed scripts to substitute them are now very
3025 different.
3026 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3027 commands can be put in a sed script portably.
3028 * doc/autoconf.texi (Setting Output Variables): Document above
3029 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
3030 use of multiline substitution.

3040 * tests/local.at: Don't attempt to check for negated character
3041 classes in shell scripts. The test was too brittle.
3043 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3045 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3046 * doc/autoconf.texi (Limitations of Builtins): Document this
3047 limitation.
3049 2005-05-24 Stepan Kasal <kasal@ucw.cz>
3051 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
3052 common code; used in many places in the tree.

3059 messages when ac_unique_file is not found.
3060 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3061 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
3062 commands, for consistency with AC_MSG_ERROR and such.
3064 * bin/autoconf.as: Make more use of "shift 2" in option processing.
3066 * bin/Makefile.am: Merge the two rules for creating scripts.

3074 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3076 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
3077 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3078 (ac_top_builddir): ... this ...
3079 (ac_top_build_prefix): ... to this; the old name is also kept, for
3080 backward compatibility.
3081 (ac_top_builddir_sub): New variable, without the trailing slash,
3082 always nonempty.
3083 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
3084 * doc/autoconf.texi (Configuration Actions): Rename
3085 ac_top_builddir to ac_top_build_prefix.
3086 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
3087 at_top_builddir to at_top_build_prefix.

3093 of confdefs.h .
3095 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3097 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3098 argument to m4_foreach. I guess it was necessary in the past,
3099 but I think it's a no-op now.
3101 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3103 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3104 ``cat <<_ACEOF'' commands to one.
3105 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3106 * lib/autoconf/status.m4: On various places, use expr instead of
3107 ``echo|sed.''
3108 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3109 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3110 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3111 a range.
3112 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
3113 the wrong patterns between ``case'' and ``esac.'' The previous
3114 code had false positives.
3116 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
3118 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3119 as on 2005-05-02.
3120 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
3121 Mention LIBOBJDIR.

3177 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
3178 abbreviations of --version and --debug.
3180 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
3182 * doc/autoconf.texi (Autoconf Language): Be more precise about
3183 quoting rules. Problems noted by Stepan Kasal.
3184 Also, throughout this document, be more careful about white space.
3185 "blank", "white space", and "space" all have different meanings
3186 and we should be careful to say what we mean.
3188 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3190 Fix C++ related problems reported by Werner Lemberg.
3191 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

3197 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
3199 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3201 * doc/autoconf.texi (Generic Functions): Typos.
3203 2005-05-02 Gary V. Vaughan <gary@gnu.org>
3205 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
3206 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
3207 set by latest automake.
3209 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
3211 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
3212 outputs 0 on GNU/Linux these days.
3214 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
3216 * doc/autoconf.texi (Autoconf Language): Add more description
3217 about quoting heuristics.
3218 (Limitations of Builtins): Describe "set -" problems.
3220 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3222 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
3223 not newline.
3225 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
3226 by AC_DEFINE; it was a mistake.
3227 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
3229 2005-04-25 Stepan Kasal <kasal@ucw.cz>
3231 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
3233 2005-04-22 Stepan Kasal <kasal@ucw.cz>
3235 * doc/autoconf.texi (External Software): Quadrigraphs are not
3236 processed correctly in AS_HELP_STRING; avoid this in the examples.
3237 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3238 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3239 comment and reduce m4_default([foo], []) to [foo].
3240 (m4_strip): Update the explanation.
3242 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3244 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3245 Remove core.conftest.* too; it's generated by Tru64 5.1.
3246 Problem reported by Jennis Pruett.
3247 * lib/autoconf/functions.m4
3248 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3249 Don't bother to remove core files; AC_RUN_IFELSE should do that
3250 for you.
3252 2005-04-19 Stepan Kasal <kasal@ucw.cz>
3254 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

3271 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
3273 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
3274 as well as configure.in. Problem reported by Gregorio Guidi.
3276 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3278 * doc/autoconf.texi (Particular Functions): Use gnulib's current

3289 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
3291 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
3292 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
3294 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3296 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3297 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3298 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3299 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3300 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3302 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3304 * NEWS: The configure command now warns you if you attempt to use
3305 a directory whose name contains a special character like space,
3306 newline, or "\".
3307 * doc/autoconf.texi (Installation Directory Variables): Allow
3308 "," in file names. Do not use \@; it's not a portable regexp.
3309 * bin/Makefile.am (edit): Likewise.
3310 * lib/Makefile.am (edit): Likewise.
3311 * tests/Makefile.am (edit): Likewise.
3312 * tests/semantics.at: Likewise.
3313 * tests/torture.at: Likewise.
3314 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3315 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3316 * doc/autoconf.texi (File System Conventions): Warn about
3317 unportable file names.
3318 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3319 (AC_INIT): Use it.
3320 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3321 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3322 ac_pwd, and quote srcdir.
3323 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3325 * doc/autoconf.texi: Fix some systematic formatting problems.
3326 ".)" needs a following @: if not at the end of a sentence, and
3327 similarly for "!)". "etc." should be preceded by a comma.
3328 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3330 2005-03-22 Bruno Haible <bruno@clisp.org>
3332 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3333 argument is often called 'build-aux'.
3335 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3337 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3338 macro AC_TRY_LINK is obsolete.
3339 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3340 `AC_CONFIG_FILES'.
3342 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3344 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3345 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3346 from a Common Lisp's `cl'.
3347 (AC_PROG_CXX): Behave according to the documentation: don't
3348 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3349 make the variable CCC precious; use `cl.exe', not `cl'.
3351 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3352 Alexandre Duret-Lutz <adl@gnu.org>
3354 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3355 /dev/null, as "configure" shouldn't read stdin, and this insulates
3356 us from problems (e.g., when testing for "cl"). Also, do this
3357 redirection before invoking "hostname" or "uname", and keep the
3358 original input stream available via...
3359 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3360 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3361 bother with "</dev/null" since it's now done at the top of
3362 'configure'.
3363 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3364 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3365 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

3368 * tests/base.at (Input/Output): New test.
3370 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3372 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3373 newline if neither \c nor -n work, as that would output two
3374 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3376 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3378 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3379 This causes that any required macros inside will get before the if.
3380 * doc/autoconf.texi (autom4te.cache): A typo.
3382 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3384 Undo previous change, except keep the change to
3385 lib/autoconf/programs.m4 that replaced grep with shell
3386 pattern-matching. This is because net-snmp configure reads stdin.
3387 Reported by Noah Misch.
3389 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3391 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3392 from /dev/null, as "configure" shouldn't read stdin, and this
3393 insulates us from problems (e.g., when testing for "cl").
3394 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3395 before invoking "hostname" or "uname".
3396 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3397 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3398 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3399 "</dev/null" since it's now done at the top of 'configure'.
3400 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3401 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3402 Also, replace grep with shell pattern-matching, to save a process.
3404 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3406 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3407 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3408 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3409 compiler.
3411 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3413 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3414 grep -q isn't portable. Improve grep -s explanation.
3415 Problem reported by Dan Manthey.
3417 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3419 * doc/autoconf.texi (Special Shell Variables): Clarify
3420 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3422 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3424 * doc/autoconf.texi: Use @acronym for DJGPP.
3425 Fix some @code's that should have been @env's, and vice versa.
3426 Sort environment variable names.
3427 Mention that shells no longer inherit IFS.
3428 Don't recommend PATH_SEPARATOR=';' so strongly.
3429 Mention that $RANDOM might expand to the empty string.
3430 "symlink" and "soft link" -> "symbolic link".
3431 Improve mktemp description (reported by Bruno Haible).
3433 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3435 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
3436 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
3437 Likewise.
3438 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
3439 Likewise.
3441 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
3443 * NEWS: Mention AT_COPYRIGHT.
3445 * tests/local.at (AT_CMP): Use diff directly on input files rather
3446 than copying them.
3448 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
3449 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
3451 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3452 and Paul Eggert <eggert@cs.ucla.edu>
3454 * tests/autotest.at (Empty test suite): New test.
3455 * tests/torture.at (Substitute and define special characters)
3456 (Substitute a 2000-byte string, Define to a 2000-byte string)
3457 (Substitute a newline, Define a newline): New tests.
3459 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3461 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
3462 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
3463 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
3464 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
3465 (Standard regular expressions): New test.
3466 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
3467 excess test name quoting.
3468 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
3469 CPPFLAGS to `configure' instead of setting it in `configure'.
3471 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
3472 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
3473 on some platforms.
3475 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
3476 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
3478 * tests/local.at (AT_CMP): New macro.
3479 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
3480 (AC_SAVE_STATE): Move environment grep...
3481 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
3482 (AT_CONFIG_CMP): New macro.
3483 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
3484 * tests/c.at (Extensions): Do not exit early.

3487 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
3488 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
3490 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
3491 (AC_COPYRIGHT): Factor header comment portion out and move into...
3492 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
3493 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
3494 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
3495 --version output.

3504 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
3506 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
3507 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3509 Try not to generated lines of unlimited length, as POSIX places a
3510 2047-byte limit on line length of portable text files.
3511 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3512 Use newline as a separator, not space.
3513 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
3514 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
3515 space.
3517 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3519 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
3520 as_func_*. Add test to check whether positional parameters
3521 are restored after function return.
3523 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
3525 * doc/autoconf.texi (Special Shell Variables): Mention _,
3526 BIN_SH, DUALCASE. Say that variables other than "status" are safe
3527 if they contain a lower-case letter. The DUALCASE problem was
3528 reported by Ralf Wildenhues.
3530 * bin/autoconf.as: Don't exit with status 0 after write failure
3531 with --help or --version.
3532 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
3533 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
3535 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3537 * doc/autoconf.texi (Limitations of Usual Tools):
3538 Unicos 9 sed limitations.
3539 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
3540 to get the option-enhanced interface on older Crays. Try ftn for
3541 Fortran 95 (newer Crays).
3543 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
3545 * man/Makefile.am (.x.1): Go back to the simple solution, but take
3546 care to echo the commands, so the user knows what's going on.
3547 Modified from a suggestion by Stepan Kasal.
3549 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
3550 with a cross reference. Derived from a suggestion by Bruce Korb.
3552 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
3554 * doc/autoconf.texi (config.status Invocation): Warn about
3555 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
3556 * doc/install.texi (Defining Variables): Likewise.
3557 Based on a proposed patch by Ralf Wildenhues.
3559 * man/Makefile.am (.x.1): Make sure the required generated files
3560 are up to date. Problem and original solution proposed by Stepan Kasal.
3561 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
3562 implicit-man-prerequisites): New rules, used by the above.

3568 2005-01-29 Stepan Kasal <kasal@ucw.cz>
3570 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3571 Update the long comment explaining it.
3573 m4_require no longer writes an ``is required by'' line to the
3574 execution stack. It contains only one bit of non-redundant
3575 information: that the macro was required, not called. And even
3576 this bit is useless in most situations: have you ever met a macro
3577 which both calls and requires the same macro?
3579 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3580 (_m4_defun_pro_outer): ... only via this macro, for the outermost
3581 macro.
3582 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
3583 (m4_expansion_stack_pop): Remove the misplaced comment.
3584 (m4_require): Don't put the ``is required by'' line to the
3585 execution stack; slightly improve the out-of-a-defun error message.
3586 (_m4_divert_grow): New macro, counter for the temporary diversions.
3587 (_m4_require_call): Use it.
3588 * tests/m4sugar.at (m4_require): Expect output without the
3589 ``is required by'' messages.
3591 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
3593 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
3594 rather than x for expr.
3596 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
3597 this is safe.
3598 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
3599 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

3604 2005-01-27 Akim Demaille <akim@epita.fr>
3606 Have autoheader honor --force.
3608 * doc/make-stds.texi, doc/standards.texi: Update from masters.
3609 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
3610 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
3611 from masters, so that FileUtils.pm's update_file provide --force
3612 support.
3613 * bin/autoheader.in: Pass $force to update_file so that
3614 config.h.in is always recreated when --force.
3616 2005-01-24 Stepan Kasal <kasal@ucw.cz>
3618 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
3620 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
3622 * doc/autoconf.texi (Limitations of Builtins): Clarify that
3623 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.

3999 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4000 "char c = '\200';" rather than "char c = 0x80;" as the

4102 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
4104 * doc/autoconf.texi (auindex): New macro.
4105 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
4106 Problem reported by Stepan Kasal.
4108 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>

4112 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
4113 in test makefile.
4114 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
4115 readable; it's not true in OS/2-emx.
4117 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
4119 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4120 "/usr/include", clear ac_x_includes instead of leaving it as "no"
4121 (trivial change). Problem and patch reported by Andrew Church in:
4122 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
4124 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
4126 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
4127 three args in examples. Problem reported by Frederik Fouvry in:

4129 Also, fix some minor spacing and punctuation bugs.
4131 2004-09-02 Akim Demaille <akim@epita.fr>
4133 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
4134 "case" to restore ordering.
4135 Reported by Stepan Kasal.
4137 2004-08-26 Akim Demaille <akim@epita.fr>
4139 * doc/autoconf.texi: Minor typos and stylos.

4151 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
4152 texinfo.tex for now (done by hand now).
4153 * Makefile.maint (wget_files, cvs_files):
4154 Remove ansi2knr.c; nobody uses it.
4155 (ansi2knr.c-url_prefix): Remove.
4156 (cvs-update): Fix test for failure. I don't know why it ever
4157 worked...
4159 * doc/autoconf.texi: Update URLs, some of which went stale.
4160 Use @uref rather than @href.
4162 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
4163 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
4165 * config/config.guess, config/config.sub, config/elisp-comp,
4166 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
4167 doc/fdl.texi, doc/standards.texi: Sync with master copy.
4169 * NEWS, TODO, configure.ac, bin/autoscan.in,
4170 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
4171 doc/install.texi, lib/Autom4te/Configure_ac.pm,

4175 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
4176 tests/tools.at, tests/torture.at:
4177 Use "file name" rather than "filename" or "path",
4178 to be consistent with the terminology of the GNU coding standards.
4180 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
4182 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
4183 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
4184 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
4185 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
4187 More fixes to support spaces in the name of the build directory.
4188 This isn't a complete fix but it's an improvement.
4190 * bin/autoconf.as (autom4te_options): New var.
4191 Use it instead of appending to AUTOM4TE, so that we can allow
4192 spaces in the build directory's absolute name.
4193 * bin/autoheader.in ($autoconf): Allow spaces in file names.
4194 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
4195 AT_CHECK_NOESCAPE): Likewise.
4196 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
4197 main program): Likewise.
4199 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
4201 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
4202 From Ralf Corsepius in:
4203 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
4205 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
4207 * doc/autoconf.texi (Function Portability): Document isinf and
4208 and isnan. From a suggestion by Kevin Ryde.
4210 * lib/Autom4te/General.pm (END): Return correct exit status even
4211 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
4213 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
4215 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4216 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4217 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4219 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4221 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4222 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4223 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4224 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4225 * lib/autom4te.in (Automake-preselections): Preselect
4226 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4228 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4230 * lib/autom4te.in (Automake-preselections): Preselect
4231 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4232 trace them.
4234 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4236 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4237 Tru64.
4238 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4239 Document problem with "`""`" in pdksh POSIX mode.
4241 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4243 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4244 with pdksh, too. Problem reported by Patrick Welche via
4245 Gary V. Vaughan.
4246 * doc/autoconf.texi (Shellology): Note that set -o posix is
4247 useful for pkdsh, too.
4249 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4251 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4252 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4253 Don't fail if ENV or BASH_ENV is readonly.
4254 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4255 etc. are read only. Problem reported by Ludovic Courtes.
4257 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4259 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4260 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4261 (trivial change)
4263 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4265 * doc/autoconf.texi (File System Conventions): Warn about
4266 names like "aux". Problem reported by Eric Blake.
4268 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4269 by zero instead of array size, so that we can use any arithmetic
4270 constant expression (instead of requiring an integer constant
4271 expression). This allows us to test expressions like DBL_MAX <
4272 LDBL_MAX, which didn't conform to the C standard using the old
4273 method.
4274 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4275 now that we can do floating-point tests at compile time.
4277 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4279 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4280 and LDBL_EPSILON, as the resulting expression isn't an
4281 integer constant expression and violates the C standard.
4282 Problem reported by Nelson H. F. Beebe. Also, check
4283 for "L" suffix, and check that long double doesn't have
4284 worse range or precision than double, that mixed-mode
4285 arithmetic doesn't generate a diagnostic, that double
4286 constants fit in long double.
4288 2004-06-03 Kevin Ryde <user42@zip.com.au>
4290 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4291 malloc(0) and realloc(NULL,size).
4293 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4294 Bob Proulx.
4296 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4298 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4299 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4300 by Jim Meyering.
4302 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4304 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4305 can be rewritten using if-then-else. Suggested by Bruno Haible.
4307 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4309 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4310 Problem reported by Stepan Kasal.
4312 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4314 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4315 change). Patch reported by Ralf Wildenhues in
4316 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4318 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4319 function F exists if the compiler and linker let you compile an
4320 expression like (F != 0). Recent versions of GCC optimize away
4321 the reference to F in that case, since every function address must
4322 be nonzero, so the link succeeds even if F does not exist.
4323 Problem reported by Manu in
4324 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4326 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4327 "Unix". Many uses changed.
4328 (Limitations of Builtins): Explain better why the ! command isn't
4329 portable.
4331 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4333 * lib/autom4te.in (Automake-preselections): Preselect
4334 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4336 2004-05-19 Kevin Ryde <user42@zip.com.au>
4338 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4339 referencing AC_FUNC_STRERROR_R.
4341 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4342 note pessimistic assumption when cross compiling.
4344 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4346 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4347 (until 2004) invoked subcommands with sh -e, contra POSIX.
4348 Reported by Kevin Ryde.
4350 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4352 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4353 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4354 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4355 `test -f " /usr/bin/grep"', which _always_ failed.
4356 (AC_PROG_SED): Ditto bogus PATH fix.
4357 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4358 requires that grep correctly supports _multiple_ `-e' options, rather
4359 than stating only that grep should accept `-e'.
4361 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4363 Port to C99, which requires that 'exit' be declared.
4365 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4366 to ensure that stdlib.h is included.
4367 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4368 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4369 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4370 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4371 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4372 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4373 when using 'exit' in a test; C99 requires that 'exit' be declared.
4375 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4377 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4378 now prefers 'grep' implementations that accept -e.
4379 (Limitations of Usual Tools): Describe problems of traditional
4380 egrep and fgrep with long input lines, and of traditional grep
4381 with -e.
4382 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4383 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4384 All callers changed. Append /usr/xpg4/bin to the PATH, for
4385 Solaris.
4386 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4387 the user with complaints about multiple -e options.
4388 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4389 Define it with AC_PROG_GREP.
4390 * configure.ac (AC_PROG_GREP): Add.
4391 * lib/freeze.mk (GREP): New macro.
4393 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4395 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4396 a possible candidate only after all others fail, rather than
4397 consulting it first. This improves backward compatibility by
4398 better reflecting the way shell selection occurred in previous
4399 versions of Autoconf, and should help to avoid triggering latent
4400 problems in other packages, such as the one in Automake where zsh
4401 is not handled robustly:
4402 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4403 Although it is not Autoconf's responsibility to work around
4404 problems in Automake, it nevertheless makes sense to avoid
4405 introducing unnecessary incompatibilites.
4407 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4408 Gary V. Vaughan <gary@gnu.org>
4410 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4411 how deeply nested we are when a suitable tool is found, set the
4412 ac_path_TOOL_found flag.
4413 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4414 nested we are in this macro. Break out of all 3 nested loops if
4415 ac_path_TOOL_found is set.
4417 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4419 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4420 of the _AS_PATH_WALK loop too if GNU flavor is found.
4422 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4424 * doc/autoconf.texi (Limitations of Make): Update documentation
4425 for `$<'. New entry `Long lines', based on a report from Simon
4426 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4427 paragraph about DJGPP, based on a mail from Richard Dawe.
4429 2004-04-20 Paul Eggert <eggert@twinsun.com>
4431 * tests/c.at (C keywords): Don't assume that GCC supports
4432 "restrict" and "inline", as sufficiently-old GCC versions do not
4433 (also, GCC configured to be in pedantic C89 mode does not).
4434 Problem reported by Sumit Pandya in:
4435 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4437 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4438 consider -g to work if it generates warnings when plain compiles
4439 don't. Problem reported by Braden McDaniel in:
4440 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4442 * doc/autoconf.texi (Slashes): New section, to document a problem
4443 reported by Jim Meyering in:
4444 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4446 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4447 linker output files before linking, to work around IRIX 6 linker bug.
4448 Problem reported by Rainer Orth in:
4449 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
4451 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4453 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4454 best tool so far counter rely on the tool path variable name to
4455 avoid checks for one tool being affected by the results of running
4456 the length check on a previous tool.
4458 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4459 match expression argument, as different greps have different
4460 regular expression flavours.
4461 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4462 literals.
4463 (AC_PROG_EGREP): Pass 'EGREP$'.
4464 (AC_PROG_GREP): Pass 'GREP$'.
4466 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4468 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4469 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4471 2004-03-29 Paul Eggert <eggert@twinsun.com>
4473 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4474 Types, Specific Compiler Characteristics, System Services,
4475 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4476 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4477 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4478 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
4479 Likewise.
4480 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
4481 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
4482 AC_TYPE_OFF_T): Likewise.
4483 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
4484 Likewise.
4486 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
4487 pacify libtool 1.5.2. Fix quoting problems in sed command.
4489 2004-03-28 Paul Eggert <eggert@twinsun.com>
4491 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4492 now defines HAVE_DECL_TZNAME if it is declared, when
4493 HAVE_STRUCT_TM_TM_ZONE is not defined.
4494 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4495 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
4496 for HAVE_TZNAME.
4498 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
4500 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
4501 superfluous backslashing of quotes (") in sed expressions;
4502 thanks to Paul Eggert.
4504 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
4506 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
4507 Fortran compiler is ifort, also added pghpf; thanks to Nelson
4508 H. F. Beebe for the bug report.
4510 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4512 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4513 quoted -cmdline argument in Portland Group compiler (bug
4514 reported by Jeffrey J. Barteet).
4516 2004-03-25 Kevin Ryde <user42@zip.com.au>
4518 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
4519 (Run Time): ... here, where it's now mentioned.
4521 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
4523 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
4524 inherits from language Autoconf-without-aclocal-m4.
4525 (Customizing autom4te): Adjust example; the cache must now be
4526 disabled for language Autoconf-without-aclocal-m4.
4528 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
4529 Nathanael Nerode <neroden@twcny.rr.com>
4531 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
4532 AC_CHECK_TOOLS): Warn if a cross-tool is found without
4533 a prefix.
4534 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,

4540 AC_CHECK_TOOLS.
4541 (Specifying Names): Document the reason for these future
4542 behavioral changes.
4543 * tests/mktests.sh: Do not generate tests for the
4544 new macros.
4545 * NEWS: Document these changes.
4547 * doc/autoconf.texi: Avoid macros with unbraced arguments,
4548 they make TeX hang up.

4553 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
4554 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
4555 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
4556 vowel.

4558 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.

4560 those for sizeof.
4562 2004-03-03 Paul Eggert <eggert@twinsun.com>
4564 * bin/Makefile.am (edit): Don't use $< in a context where
4565 POSIX doesn't require support for it. Use $@.in instead.

4570 2004-02-23 Gary V. Vaughan <gary@gnu.org>
4572 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
4573 from the next generation of Libtool.

4576 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4578 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
4579 is not always thread-safe. Report from Nathanael Nerode.
4581 2004-02-18 Paul Eggert <eggert@twinsun.com>
4583 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4584 problem on QNX reported by Stephen Rasku in
4585 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4587 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
4588 $(m4sh_m4f_dependencies); this removes a FIXME.
4589 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
4590 (MAINTAINERCLEANFILES): Split into pieces,
4591 one per related section. Add $(srcdir)/wrapper.in.

4596 AC_SUBST provides no portable way to escape literal newlines.
4598 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4599 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4600 Darwin uses -lcrt2.o and there's little point to cataloging all
4601 the system variants. Partial fix reported by Andreas Waechter in:
4602 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
4603 for bug reported by Nelson H. F. Beebe in:

4606 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
4608 * doc/autoconf.texi (AU_DEFUN): Fix English,
4609 suggested by Paul Eggert.
4610 * lib/autoconf/autoupdate.m4: Correct reference to
4611 acobsolete.m4, suggested by Alexandre Duret-Lutz.
4613 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
4615 * bin/autoupdate.in: Define __file__ so that warnings
4616 refer to the correct file.
4617 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
4618 the behavior of the third argument.
4619 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4620 correctly the behavior of the third argument. Document
4621 what the three macros that AU_DEFUN defines do. Fix
4622 warning message when the third argument includes $0
4623 (reported by Alexandre Duret-Lutz).
4625 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4626 Eric Sunshine <sunshine@sunshineco.com>
4627 Paul Eggert <eggert@twinsun.com>
4629 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
4630 (AS_INIT): Output shell initialization there. Removed optional
4631 parameter. Expand _AS_SHELL_FN_SPY.
4632 (AS_INIT_WITH_SHELL_FN): Removed.
4633 (_AS_SHELL_FN_SPY): New macro.
4634 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
4635 macros.
4636 (AS_SHELL_SANITIZE): Remove loop to find better shell
4637 and documentation for the parameter.
4638 (_AS_DETECT_BETTER_SHELL): Move it here.
4639 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
4640 (_AS_RUN): Move it here, support testing with eval.
4641 (AS_REQUIRE_SHELL_FN): Require shell functions when
4642 it is used.
4643 (_AS_LINENO_WORKS): Put around braces, we do not
4644 trigger the bash bug anymore.
4645 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
4646 use AS_INIT_WITH_SHELL_FN.
4647 * bin/autoconf.in, tests/wrapper.in: Regenerated.
4649 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4651 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
4652 * doc/autoconf.texi: Don't say that the third parameter
4653 is broken.
4654 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
4655 (AU_DEFUN): Honor the third parameter, create autoupdate
4656 macros with AU_DEFINE.
4657 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
4658 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
4659 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
4660 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
4661 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

4666 * lib/autoconf/status.m4: Remove FIXME.
4667 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
4668 that the macro is not present anymore in the updated
4669 configure.ac.
4670 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
4671 of autoupdate.
4673 2004-01-28 Paul Eggert <eggert@twinsun.com>
4675 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
4676 copyright years.
4677 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
4678 2003 (except 1997) to the list of copyright years. This undoes
4679 the 2003-05-22 change, which removed the older years from the list.
4680 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4682 2004-01-27 Gary V. Vaughan <gary@gnu.org>
4683 Albert Chin-A-Young <china@thewrittenword.com>
4685 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
4686 grep or ggrep program in PATH that accepts as long lines as
4687 possible.
4688 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
4689 AC_PROG_GREP.
4690 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
4691 egrep and fgrep respectively if $GREP -E/-F don't work.
4692 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
4693 _AC_PROG_GREP, and AC_PROG_SED.
4694 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
4695 longest input length accepted by a command.
4696 (AC_PROG_SED): Use it.
4697 * doc/autoconf.texi (Particular Programs): Document the changes.
4698 * NEWS: Updated.
4700 2004-01-27 Paul Eggert <eggert@twinsun.com>
4702 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

4704 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
4705 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
4707 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
4708 bin/autoconf.in, config/Makefile.in, config/config.guess,
4709 config/config.sub, config/install-sh, config/mdate-sh,

4722 sources.
4724 2004-01-26 Paul Eggert <eggert@twinsun.com>
4726 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4727 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4728 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4729 not <inttypes.h>. Problem reported by Tim Mooney in
4730 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4731 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4732 Likewise.
4734 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4735 otherwise "make check" fails because it forbids cmp (I guess
4736 because cmp treats files as binary on DOS-like systems).
4738 * tests/mktests.sh: Update copyright date to 2004, since some tests
4739 have changed in 2004.
4741 2004-01-23 Gary V. Vaughan <gary@gnu.org>
4743 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
4744 non-truncating sed or gsed program in PATH.
4745 * tests/acprograms.at: Add it.
4746 * doc/autoconf.texi (Particular Programs): Document it.
4747 * NEWS: Updated.
4749 2004-01-15 Paul Eggert <eggert@twinsun.com>
4751 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4752 -std1 disables some useful extensions on Tru64. Problem reported
4753 by N. Lichtmaier in
4754 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4756 2004-01-14 Paul Eggert <eggert@twinsun.com>
4758 * doc/autoconf.texi (Programming in M4sh): Document that
4759 AS_MKDIR_P succeeds if the destination is a symbolic link
4760 to an existing directory.
4761 (Limitations of Usual Tools): Note that mkdir -p might not
4762 succeed on symlinks to directories.
4764 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4766 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
4767 * bin/autoheader.in: Grammar fix in message.
4768 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
4769 Test for dir before calling mkdir -p. (trivial changes)
4771 2004-01-13 Eric Blake <ebb9@byu.net>
4773 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
4774 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
4776 2004-01-10 Jim Meyering <jim@meyering.net>
4778 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
4780 2004-01-09 Paul Eggert <eggert@twinsun.com>
4782 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4783 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4784 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4785 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4786 AC_COMPILE_IFELSE, since we now assume our caller invokes
4787 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4788 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4789 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4790 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4792 2004-01-07 Paul Eggert <eggert@twinsun.com>
4794 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4795 `"'...'"`, as it's confusing (and I suspect it may not work on
4796 some platforms). The code was incorrect anyway, as it assumed
4797 that \$ evaluated to itself in that context. Reported by
4798 Alexandre Duret-Lutz.
4800 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
4802 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
4803 and _LT_AC_TAGCONFIG.
4805 2004-01-06 Paul Eggert <eggert@twinsun.com>
4807 * doc/autoconf.texi (One Macro Call): Fix an incorrect
4808 example, and add more examples. Reported by Eric Sunshine.
4810 2004-01-05 Paul Eggert <eggert@twinsun.com>
4812 * doc/autoconf.texi (Limitations of Usual Tools):
4813 Remove warning against "rm -fr" introduced yesterday; it
4814 was a false alarm.
4816 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
4817 autoscan, autoupdate, ifnames): Don't use chmod -w.
4818 * lib/Makefile.am (autom4te.cfg): Likewise.
4819 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
4820 "chmod -w".
4822 2004-01-04 Paul Eggert <eggert@twinsun.com>
4823 Paolo Bonzini <bonzini@gnu.org>
4825 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
4826 by doing lineno substitution only on lines containing "$LINENO".
4828 2004-01-04 Paul Eggert <eggert@twinsun.com>
4830 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
4831 Use "rm -f" to remove conftest.sed, not plain "rm".
4832 Bug reported by David Relson in
4833 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
4835 * Makefile.am (autom4te-update):
4836 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
4837 * Makefile.maint (my-distcheck, do-po-update): Likewise.
4838 * doc/autoconf.texi (Guidelines): Likewise.
4839 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

4845 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
4846 srcdir): Likewise.
4847 * doc/autoconf.texi (Limitations of Usual Tools):
4848 Warn against "rm -fr".
4850 2004-01-03 Paul Eggert <eggert@twinsun.com>
4852 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
4853 -c -o might not work. From a suggestion by Kevin Ryde.
4854 (C Compiler, Generating Sources, Limitations
4855 of Usual Tools, Limitations of Make, Making testsuite Scripts):
4856 Don't put '-o' after non-options, as POSIX doesn't allow this.
4857 Mention that cc's name might be gcc or c89 or whatever.
4859 2004-01-04 Kevin Ryde <user42@zip.com.au>
4861 * doc/autoconf.texi: Add various further index entries.
4863 2003-12-29 Paul Eggert <eggert@twinsun.com>
4865 * bin/autoreconf.in (autoreconf_current_directory):
4866 Fix typo: mkdir without umask arg.
4868 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
4870 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
4871 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
4872 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
4873 explanation clearer.
4875 2003-12-24 Andreas Schwab <schwab@suse.de>
4877 * doc/autoconf.texi (Default Includes): Fix misspelling of
4878 AC_INCLUDES_DEFAULT.

4882 * configure.ac: Test if sh -n works.
4883 * configure: Regenerate.
4884 * tests/atlocal.in: Store the result here.
4885 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
4886 tools.at, looking in atlocal's ac_cv_sh_n_works instead
4887 of explicitly testing.
4888 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
4889 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
4890 * tests/tools.at (Syntax of the shell scripts): Simplify
4891 using AT_CHECK_SHELL_SYNTAX.
4892 (Syntax of the Perl scripts): Remove definition of
4893 AT_CHECK_PERL_SYNTAX.
4895 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
4897 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
4898 stderr to /dev/null.
4899 * bin/autoconf.in: Regenerate.
4900 * bin/wrapper.in: Regenerate.
4902 2003-11-26 Paolo Bonzini <bonzini@gnu.org>

4905 Extracted from AS_SHELL_SANITIZE.
4906 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
4907 macros.
4908 (AS_SHELL_SANITIZE): Move reinvocation code from
4909 _AS_LINENO_WORKS, use it to find out if shell
4910 functions work.
4911 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
4912 does not work.
4913 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
4914 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

4925 (&sizes): New.
4926 Use them.

4928 them on the fly.
4930 2003-11-24 Akim Demaille <akim@epita.fr>
4932 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

4960 parameter of AU_DEFUN.
4961 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.

4965 the expanded body, consistently with other macros such as AC_USG.
4967 2003-11-17 Paul Eggert <eggert@twinsun.com>
4969 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes

4971 patch 3 reported by Eric Sunshine.
4973 2003-11-15 Kevin Ryde <user42@zip.com.au>
4975 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
4976 than $target since the latter is not usual, add guidelines on when to

5136 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
5137 cross test.
5139 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
5141 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
5142 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

5153 Issue a more-informative diagnostic.
5154 Problems reported by Eric Sunshine.
5156 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5158 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
5159 -mGLOB_options_string stuff for Intel ifc, which can cause
5160 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

5169 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
5170 that future autopoint/aclocal/automake/autoreconf will be able

5179 -lcrt[01].o.
5181 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
5183 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5184 cache variable instead of $G77 to decide whether to include -O2,
5185 since $G77 is specific to Fortran 77.

5189 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
5190 free" flag. Re-order flags tested into rough order of popularity.
5192 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5194 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
5195 arguments so that it can be used with syntax identical to
5196 AC_PROG_F77, and so that we can more easily decide to
5197 remove/deprecate the DIALECT optional argument in the future if it
5198 proves troublesome.
5199 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
5200 non-freeform-supporting compilers. Document freeform flags.
5202 2003-10-03 Akim Demaille <akim@epita.fr>
5204 * configure.ac: Look for emacs, not macs.

5207 2003-10-03 Akim Demaille <akim@epita.fr>
5209 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
5210 * bin/autoreconf.in (autoreconf_current_directory): Create the

5212 Suggested by Alexandre Duret-Lutz.
5214 2003-10-03 Akim Demaille <akim@epita.fr>
5216 * configure.ac: Quotation and formatting changes.

5239 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
5241 2003-09-30 Akim Demaille <akim@epita.fr>
5243 * config/announce-gen (&print_news_deltas): Extracted from...
5244 (&print_changelog_deltas): here.

5263 Problem reported by Lars J. Aas in
5264 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
5265 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5266 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5267 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5269 2003-09-26 Akim Demaille <akim@epita.fr>
5271 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5272 directory for AC_CONFIG_COMMANDS' first argument exists.
5273 This makes valid the invocation of _AC_SRCPATH that follows.
5274 Reported by Eric Sunshine.
5275 * doc/autoconf.texi (Configuration Commands): Adjust.
5277 2003-09-26 Akim Demaille <akim@epita.fr>
5279 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5280 Reported by Ralf Corsepius.
5282 2003-09-26 Akim Demaille <akim@epita.fr>
5284 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5285 arguments.
5286 Actually, use AU_ALIAS.
5287 From Bruno Haible.
5289 2003-09-26 Paul Eggert <eggert@twinsun.com>
5291 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
5292 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
5293 Problem reported by Eric Sunshine in:

5296 2003-09-26 Akim Demaille <akim@epita.fr>
5298 The test suite are sometimes assigning timings incorrectly.
5299 Reported by Henk Krus.
5300 Diagnosed by Nicolas Joly.
5302 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5303 AT_help_all.
5304 Instead of making AT_help a sequence of assignments to grow
5305 $at_help_all, just make AT_help_all be the growing contents of
5306 $at_help_all, and make a single assignment in...
5307 (AT_INIT): here.
5308 (at_times_skip): Flip the meaning and rename as...
5309 (at_times_p): this.
5310 (AT_INIT): When summarizing the test that ran, remove
5311 $at_times_file after use, and check it is present before trying to
5312 use it.
5314 2003-09-25 Akim Demaille <akim@epita.fr>
5316 Version 2.57d.
5318 * bin/Makefile.am (edit): Handle '@configure_input@'.

5320 (ifnames): chmod -w.
5321 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5322 executables, not bin/ executables! Otherwise all the magic needed
5323 to find non installed files is turned off. This caused a failure
5324 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5325 as found in its environment (sent by tests/autoreconf): pointing
5326 to bin/autom4te that could not find its files.
5327 * tests/mktests.sh: Force the replacement of generated files, for
5328 the sake of "mv" program that are interactive when overwriting a
5329 -w file.
5330 * config/install-sh: Upgrade from CVS Automake.
5332 2003-09-23 Paul Eggert <eggert@twinsun.com>
5334 * doc/autoconf.texi (Limitations of Builtins): Document test -h
5335 versus test -L issues.
5337 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
5338 Paul Eggert <eggert@twinsun.com>
5340 Trivial change to support GCC's configuration procedure.
5341 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5342 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5343 about inconsistency if the preprocessor is set to give errors for
5344 any warning.
5345 * doc/autoconf.texi (C Compiler Characteristics): Document this.
5347 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
5349 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
5350 and XFile.pm from Automake.

5361 from masters.
5363 2003-09-12 Akim Demaille <akim@epita.fr>
5365 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
5366 not asm/types.h.
5368 2003-09-11 Akim Demaille <akim@epita.fr>
5370 * doc/autoconf.texi (Header Portability): linux/random.h.
5371 From Peter Hendrickson.
5373 2003-09-10 Akim Demaille <akim@epita.fr>
5375 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
5376 willing to edit the output files.
5378 2003-09-10 Akim Demaille <akim@epita.fr>
5380 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
5381 and AC_FC_FREEFORM.
5382 * tests/mktests.sh: Skip AC_FC_SRCEXT.
5383 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

5398 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
5399 Improve the accuracy of the wording about obsolescence.
5400 From a suggestion by Ian Lance Taylor in
5401 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
5403 2003-09-05 Paul Eggert <eggert@twinsun.com>
5405 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
5406 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
5408 2003-09-04 Akim Demaille <akim@epita.fr>
5410 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
5411 AC_FUNC_WAIT3.
5413 2003-09-04 Akim Demaille <akim@epita.fr>
5415 * bin/autom4te.in: Use &fatal where more appropriate than &error.
5416 (freeze): When exiting, use $exit_code.
5417 * lib/autoconf/fortran.m4: Comment changes.
5419 2003-09-04 Akim Demaille <akim@epita.fr>
5421 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
5423 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
5425 Add support for newer Fortran dialects. The F77 interface is
5426 unchanged, and continues to support Fortran 77. New FC macros
5427 correspond to all the old F77 macros, with output variables FC,
5428 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5429 available dialect, but older dialects can be specified. There are
5430 new macros AC_FC_SRCEXT to set the source extension, and
5431 AC_FC_FREEFORM to accept free-form source files.
5433 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
5434 New macros.
5435 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

5461 Document problems with timestamp resolution that 'make', 'cp -p', and
5462 'touch -r' have.
5464 2003-08-27 Akim Demaille <akim@epita.fr>
5466 * tests/m4sugar.at (cross_warning): Make sure to enable the
5467 output, so that we can track spurious m4sugar output.
5468 * tests/local.at: Require 2.57.
5469 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5470 are defaulted by AT_CHECK anyway.
5471 Use AT_CHECK_AUTOM4TE.
5472 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5473 missing dnl.
5475 2003-08-27 Akim Demaille <akim@epita.fr>
5477 * bin/autoheader.in: Issue the "Using auxiliary..." message only
5478 when -Wobsolete is set.
5479 Set it on by default.
5480 Suggested by Klee Dienes.
5482 2003-08-27 Akim Demaille <akim@epita.fr>

5491 after AC_OUTPUT.
5493 2003-08-25 Akim Demaille <akim@epita.fr>
5495 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
5496 CVS Bison.
5498 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>

5512 2003-08-22 Akim Demaille <akim@epita.fr>
5514 Version 2.57b.
5516 * Makefile.cfg (local-checks-to-skip): New.
5517 * Makefile.maint (local-check): Rename as...
5518 (local-checks-available): this.
5519 (local-check): New.
5521 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
5522 * configure.ac: Require Automake 1.7.6.
5524 2003-08-22 Akim Demaille <akim@epita.fr>
5526 Output stack traces in warnings.
5528 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
5529 Replace the former...
5530 (m4_warn): Pass the call stack to _m4_warn.
5531 * bin/autom4te.in: Adjust to output the call stack.
5532 * tests/m4sugar.at (m4@&t@_warn): Adjust.
5534 2003-08-22 Akim Demaille <akim@epita.fr>
5536 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
5537 * bin/autom4te.in: Adjust.
5539 2003-08-21 Akim Demaille <akim@epita.fr>
5541 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
5542 (&verbose): Remove.
5543 (&getopt): Adjust the note and verb channels, depending upon
5544 --verbose.
5545 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
5546 * bin/autoupdate.in: Adjust.
5547 Use &verb, not &verbose.
5549 2003-08-21 Akim Demaille <akim@epita.fr>
5551 * bin/autoheader.in (&parse_args): Use &parse_warnings and
5552 &parse_WARNINGS.
5553 ($help): Use Autom4te::ChannelDefs::usage.
5554 * bin/autoscan.in: Use Autom4te::ChannelDefs.
5555 * lib/Autom4te/General.pm: Don't export error: you don't own it.
5557 2003-08-21 Akim Demaille <akim@epita.fr>
5559 First stab at preserving warnings between calls to autom4te,
5560 including when the cache is used.
5562 There are still several issues: (i) there are too many runs of m4
5563 (one for include, one for warnings, and some more), (ii) warnings
5564 spreading on several lines are not handled gracefully, (iii) the
5565 code meant to have the call stack display for errors does not work
5566 (its handling should move from m4 to autom4te).
5568 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5569 Use them.
5570 (@preselect): Add m4_warn.
5571 ($exit_status): Remove, use $exit_code.
5572 ($help): Use Autom4te::ChannelDefs::usage.
5573 (&handle_m4): No longer define the m4_warnings.
5574 At each run, extract and report the warnings.
5575 Always cache the result, including if the exit status is on
5576 failure, since if nothing changes, we should result in the same
5577 failure, hence we can use the cache.
5578 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5579 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5580 Remove.
5581 (m4_warn): Redefine as a do-nothing: it is its invocation that
5582 matters, as warnings are now reported via traces.
5583 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5584 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5585 the latter reveals calls to the former.
5587 Adjust the tests.
5589 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5591 2003-08-21 Akim Demaille <akim@epita.fr>
5593 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
5594 Use them.
5596 2003-08-21 Akim Demaille <akim@epita.fr>
5598 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
5599 forward order.
5600 * lib/Autom4te/ChannelDefs.pm: Doc typos.
5601 (&parse_warnings): Accept a list of warning requests.
5602 (&usage): Return a string, not a side effect.
5603 (cross): New warning category.
5605 2003-08-21 Akim Demaille <akim@epita.fr>
5607 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
5608 (&require_configure_ac): Accept an optional directory argument.
5609 ($configure_ac): Remove.
5610 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
5611 (&catfile): Remove.
5612 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
5613 * bin/autoscan.in: Adjust.
5615 2003-08-20 Akim Demaille <akim@epita.fr>
5617 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5618 Reported by Alexandre Duret-Lutz.
5620 2003-08-20 Akim Demaille <akim@epita.fr>
5622 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5623 * bin/autom4te: Adjust.
5624 In particular, be Autoconf tools are really silent when properly
5625 working, bind the verbosity of the 'note' channel to $verbose.
5626 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5627 (&xsystem, &contents): Remove, since they are exported by...
5628 * lib/Autom4te/FileUtils.pm: this.
5629 More perldoc.
5630 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
5631 * lib/Autom4te/FileUtils.pm: here.
5633 2003-08-20 Akim Demaille <akim@epita.fr>
5635 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
5636 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
5637 from CVS Automake.
5639 2003-08-20 Akim Demaille <akim@epita.fr>
5641 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
5642 (autom4te-update): New.
5643 * Makefile.cfg (update): Bind autom4te-update.
5645 2003-08-19 Derek Price <derek@ximbiot.com>
5647 * lib/autotest/general.m4: Comment various HELP_* diversions.
5648 (PARSE_ARGS_BEGIN): New section for option parsing related
5649 initialization.

5657 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
5659 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
5661 * lib/autom4te.in (Automake-preselections): Preselect
5662 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
5663 and m4_sinclude.
5665 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
5667 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...

5669 * doc/autoconf.texi (autom4te Invocation): Mention
5670 Autoconf-without-aclocal-m4.

5675 RUN-IF-PASS optional arguments.

5684 STDOUT & STDERR arguments.
5686 2003-08-14 Derek Price <derek@ximbiot.com>
5688 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
5689 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
5690 shorter column three. Add DESCRIPTION to log file content.
5692 2003-08-13 Derek Price <derek@ximbiot.com>
5694 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
5695 output.
5697 2003-08-12 Derek Price <derek@ximbiot.com>
5699 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
5700 (AT_CHECK_NOESCAPE): Move core functionality to...
5701 (_AT_CHECK): ...this new macro.
5703 2003-08-07 Derek Price <derek@ximbiot.com>
5705 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
5706 (AT_CHECK_NOESCAPE): ...to this new macro.
5708 2003-07-31 Paul Eggert <eggert@twinsun.com>
5710 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
5711 in Bash 2.01. Problem reported by Brian Gough in
5712 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
5714 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
5716 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
5717 -lcrt1.o, for OS X. (trivial change)
5719 2003-07-07 Paul Eggert <eggert@twinsun.com>
5721 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
5722 inside '#ifndef __cplusplus'. Problem reported by
5723 Bob Friesenhahn.
5725 2003-07-06 Bill Clarke <llib@computer.org>
5727 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
5728 'long', not 'int', for benefit of Sun's recent C++ compilers
5729 (trivial change). See:
5730 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
5731 (This really should be 'intptr_t', not 'long', but that would
5732 take more work.)
5734 2003-06-25 Akim Demaille <akim@epita.fr>
5736 * lib/Makefile.am (autom4te.cfg): Make it read only.
5737 Depend on Makefile since it contains substitutions.
5738 From Paolo Bonzini.
5739 * lib/autom4te.in (args): Add local.at? for Autotest args.
5740 This change was made on autom4te.cfg which is generated.
5741 Reported by Raja R. Harinath.
5743 2003-06-25 Akim Demaille <akim@epita.fr>
5745 * doc/autoconf.texi (Header Portability): sys/mount.h.
5746 From Gareth McCaughan.
5748 2003-06-23 Akim Demaille <akim@epita.fr>
5750 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5751 not all of them. This fixes 1. the fact that when testing
5752 Autoconf there are many many config.log, 2. the incorrect use of
5753 top_srcdir to find config.log.
5754 Don't mix the detailed output of failed test with the summary of
5755 failures. Rather, append detailed log afterwards.
5757 2003-06-23 Akim Demaille <akim@epita.fr>
5759 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5760 always run: output config.log on $at_group_log.
5762 2003-06-23 Akim Demaille <akim@epita.fr>
5764 * tests/torture.at (#define header templates): Don't use quotes in
5765 C++ comments as it puzzles Emacs' sh font-lock-mode.
5767 2003-06-23 Akim Demaille <akim@epita.fr>
5769 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
5770 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
5771 * tests/atspecific.m4: Rename as...

5774 * tests/local.at: here.
5775 * tests/Makefile.am: Adjust.
5776 * doc/autoconf.texi (testsuite Scripts): Adjust.
5778 2003-06-21 Kevin Ryde <user42@zip.com.au>
5780 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
5781 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
5782 ensuring we add -std1 for full-ANSI.
5784 * doc/autoconf.texi (hdrindex): New macro.
5785 Add index entries for portability of various standard header files.
5787 2003-06-20 Akim Demaille <akim@epita.fr>
5789 * configure.ac: Bump to 2.57b.
5791 2003-06-20 Akim Demaille <akim@epita.fr>
5793 Version 2.57a.
5795 2003-06-20 Akim Demaille <akim@epita.fr>
5797 * bin/autom4te.in: Don't rely on $HOME being defined.
5798 Reported by Marc Espie as PR/233.
5800 2003-06-20 Akim Demaille <akim@epita.fr>
5802 * lib/autotest/general.m4: Use at_times_file only if used.
5803 From Nicolas Joly.
5805 2003-06-20 Akim Demaille <akim@epita.fr>
5807 * config/config.guess, config/config.sub, config/elisp-comp,
5808 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
5809 Update from masters.
5811 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
5813 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
5814 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
5815 (TEST_SCRIPT): New diversion.
5816 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
5817 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
5818 (AT_INIT): Support for expected failures.
5820 2003-06-02 Akim Demaille <akim@epita.fr>
5822 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
5823 changes.
5824 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
5825 Autoconf nor Automake.
5826 (&contents): New, from Automake.
5827 PODify.
5829 2003-05-28 Paul Eggert <eggert@twinsun.com>
5831 * NEWS, doc/autoconf.texi (Particular Functions),
5832 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
5833 is the inverse of localtime.
5835 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
5837 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
5838 (handle_exec_errors): New function. Work around $! being
5839 altered by WEXITSTATUS.
5840 (xqx, xsystem): Use handle_exec_errors.
5842 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5844 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5845 Do not call `_exit()', simply modify `$?'.
5846 (xsystem): Reset $! before running system, and check it afterward.
5847 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
5848 63 for version mismatches.
5850 2003-05-23 Akim Demaille <akim@epita.fr>
5852 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
5853 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
5854 the middle of a line).
5855 * lib/m4sugar/m4sugar.m4: Likewise.
5856 Remove useless spaces in comments.
5858 2003-05-23 Akim Demaille <akim@epita.fr>
5860 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
5861 exit 63, so that we (or Automake's "missing") can tell the
5862 difference with a plain failure.
5863 * doc/autoconf.texi (Notices): Adjust.
5865 2003-05-23 Akim Demaille <akim@epita.fr>
5867 * Makefile.am, bin/Makefile.am, config/Makefile.am,
5868 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
5869 White spaces cleanup.
5871 2003-05-22 Jim Meyering <jim@meyering.net>
5872 Paul Eggert <eggert@twinsun.com>
5874 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5875 Remove `#include <stdlib.h>' from the list; we should never
5876 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5877 resulting namespace pollution would cause other tests to fail.
5878 Configure scripts run with some older versions of g++ and HP's
5879 aCC would fail due to such an #include. Problems reported by
5880 Matthew Mueller in <http://bugs.debian.org/120704> and by
5881 Keith Bostic in
5882 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5883 In the test, use the test declaration before including <stdlib.h>,
5884 as that's closer to how it'll be used.
5886 2003-05-23 Akim Demaille <akim@epita.fr>
5888 * doc/autoconf.texi (Header Portability): ucred.h.
5889 From Ian Redfern.
5891 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5893 Overhaul Autotest's logging: generate separate log files
5894 in testsuite.dir/NNN/testsuite.log, and append them to
5895 testsuite.log instead of re-running the test verbosely.
5897 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5898 file descriptor, write 0 to at_status_file instead of setting
5899 at_status=0, initialize some new variables (at_status_file,
5900 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
5901 to rerun the tests, instead append the at_group_log to the
5902 at_suite_log when a test fails.
5903 (AT_SETUP): pipe the test case's output into at_tee_pipe,
5904 with the AS_MESSAGE_LOG_FD redirected to stdout.
5905 (AT_CLEANUP): save the output status in $at_status_file
5906 and restore it, redirect the AS_MESSAGE_LOG_FD back to
5907 its original place.
5908 (AT_CHECK): since tests are run with a redirected stdout,
5909 and used to be re-run in verbose mode, turn some $at_verbose
5910 into echo, and don't redirect the output of testing stdout
5911 and stderr.
5913 * lib/autotest/autoconf.texi (testsuite Scripts): Update
5914 the name of the debugging directory and information about
5915 its contents.
5917 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5919 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd

6032 and truncate.
6034 2003-05-06 Akim Demaille <akim@epita.fr>
6036 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6037 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6038 by aclocal.m4 is changed it might require the importing of another
6039 m4 extension file, i.e., aclocal must be run.
6041 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6042 (&parse_args): Use --force with aclocal if required and supported.

6050 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6051 argument instead of a file name, so that the request file remains
6052 open during the whole autom4te run.
6053 ($icache_file): New.
6054 (&freeze): Lock the $icache_file.
6056 2003-04-29 Derek Price <derek@ximbiot.com>
6058 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6059 seperator with m4_append_uniq(). It doesn't work.
6060 (AT_CLEANUP): Add `;' to end of at_help_all.
6061 (AT_INIT): Allow --keywords to be specified more than once. When
6062 grepping $at_help_all for keywords, use the field and keyword
6063 seperators to ensure a complete keyword match. Alter at_prev handling
6064 to support the new --keywords behavior.
6066 2003-04-27 Karl Berry <karl@freefriends.org>
6068 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6069 align better with others. I also made some of the individual
6070 entries on one line, for brevity and to make it easier for me to
6071 sort my dir-example file in the Texinfo distribution :).
6073 2003-04-12 Jim Meyering <jim@meyering.net>

6138 header causes problems.
6140 2003-03-28 Akim Demaille <akim@epita.fr>
6142 * tests/torture.at (Configuring subdirectories): Require aclocal
6143 1.4, otherwise the test fails, as it does support configure.ac.

6148 * doc/autoconf.texi (C Compiler): `#line' portability.

6170 * tests/m4sh.at (AS_HELP_STRING): New test.
6172 * tests/acgeneral.at: Regenerated.
6174 2003-03-26 Derek Price <derek@ximbiot.com>

6181 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

6215 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
6216 Tru64 make in the "target lookup" section.
6217 (Automake): Automake 1.5+ no longer requires special tools to be
6218 present on the developer's host.

6234 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
6235 to cope with DOS-style absolute paths, when constructing
6236 ${ac_make}.
6238 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
6239 When constructing paths with IFS=:, quote the path. If we're
6240 constructing a DOS-style absolute path, we don't want to split it
6241 on the colon.
6243 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
6244 in description.
6246 2003-02-25 Pavel Roskin <proski@gnu.org>

6258 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
6259 to fix a mismatch between example and discussion.
6261 2003-02-24 Kevin Ryde <user42@zip.com.au>
6263 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
6264 format starting with "-".
6266 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6268 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
6269 is not portable inside Makefile.
6271 2003-02-20 Akim Demaille <akim@epita.fr>
6273 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
6274 compiler says yeah, but preproc says nope, compiler is right.
6275 Conversely, prompt the reader to send a bug report to the
6276 maintainers of the package, not of Autoconf.
6278 2003-02-20 Klee Dienes <kdienes@apple.com>
6280 * bin/autoreconf.in (autoreconf_current_directory): Properly
6281 handle an empty aclocal.m4.

6286 $ac_prefix_program.
6287 From Larry Jones.
6289 2002-12-23 Paul Eggert <eggert@twinsun.com>
6291 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6292 innocuous variant befor including <limits.h> or <assert.h>. This
6293 works around a bug reported by Albert Chin: HP-UX 11i
6294 (and earlier versions) have a <limits.h> that declares
6295 gettimeofday and many other functions.
6297 2002-12-03 Paul Eggert <eggert@twinsun.com>
6299 Version 2.57.
6301 * NEWS, configure.ac: Update version.
6303 * doc/fdl.texi: Upgrade to FDL version 1.2.
6305 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6306 nontrivially in main's body, so that f's external declaration is
6307 not optimized away in AIX. This should fix the bug reported by
6308 Martin Frydl in
6309 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6311 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6312 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6313 defined, to support freestanding compilers. This should fix the
6314 bug reported by Momchil Velkov in
6315 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6317 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6318 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
6319 obsolete AC_CHECK_TYPE. The missing empty arg was reported
6320 by Simon Josefsson in

6323 * Makefile.maint (www-gnu): New macro.
6324 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
6325 the location has moved.
6327 2002-12-02 Martin Frydl <martin@systinet.com>
6329 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6330 \(.*\) match is too long and there is something more to be checked.
6331 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
6333 2002-11-15 Akim Demaille <akim@epita.fr>

6338 From Paul Eggert.
6339 * config/move-if-change: Indenting changes.
6340 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
6341 * configure.ac (AM_INIT_AUTOMAKE): here.
6342 Require 1.7.1.
6344 2002-11-14 Akim Demaille <akim@epita.fr>
6346 Version 2.55.
6348 * config/config.guess, config/config.sub, config/install-sh:
6349 Update from masters.
6351 2002-11-14 Akim Demaille <akim@epita.fr>
6353 * Makefile.maint: Sync with Bison, i.e.:
6354 (po-check): Scan .l and .y files instead of the
6355 .c and the .h files that they generate. This fixes the bug
6356 reported by Tim Van Holder in:
6357 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6358 Look for N_ as well as for _. Try to avoid matching #define for
6359 N_ and _.
6360 From Paul Eggert.
6362 2002-11-14 Akim Demaille <akim@epita.fr>
6364 * doc/autoconf.texi (C Compiler): Compiling several files at once.
6365 From Paul Eggert and Albert Chin-A-Young.
6367 2002-11-14 Akim Demaille <akim@epita.fr>
6369 * doc/autoconf.texi (C Compiler): Solitary backslashes.
6370 From Paul Eggert and Albert Chin-A-Young.
6372 2002-11-14 Kevin Ryde <user42@zip.com.au>
6374 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6375 than assigning in main, to avoid HP cc +O3 optimizing it away.
6377 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6379 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6380 option. Process --recheck after parsing all options. Pass -q
6381 option to configure on --recheck.
6382 (AC_OUTPUT): Pass -q from configure to config.status.
6383 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
6384 arguments to record.
6385 * doc/autoconf.texi (config.status Invocation): Document
6386 config.status -q option.
6388 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
6390 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
6391 Makefile.in if Makefile.am exists.
6392 (output): Strip `.am' from Makefiles. Don't
6393 output AC_CONFIG_FILES if no Makefiles were found.
6395 2002-11-07 Akim Demaille <akim@epita.fr>
6397 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
6398 (local_updates): New.
6399 * Makefile.maint: Update, from CVS Bison.
6400 (local_updates): New.
6402 2002-11-06 Akim Demaille <akim@epita.fr>
6404 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
6405 declaration in extern "C" too.
6406 Reported by Roberto Bagnara.
6408 2002-11-06 Akim Demaille <akim@epita.fr>
6410 * tests/torture.at (Configuring subdirectories): Don't use grep
6411 -w.
6412 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
6413 Reported by Ezra Peisach.
6415 2002-11-05 Akim Demaille <akim@epita.fr>
6417 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6418 Remove.
6419 We _have_ to stop using the old compatibility scheme that tried to
6420 avoid useless backslashes because Libtool 1.4.3 contains a
6421 AC_DEFINE([error_t], [int],
6422 [Define to a type to use for \`error_t' if it is not
6423 otherwise available.])
6424 We _have_ to quote the single quote and backslashes with \. The
6425 old compatibility scheme saw that ` was backslashed, and therefore
6426 did not quote the single quote. Hence before this patch, Autoconf
6427 was not compatible with Libtool.
6429 2002-11-04 Paul Eggert <eggert@twinsun.com>
6431 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
6432 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,

6759 2002-10-22 Akim Demaille <akim@epita.fr>
6761 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

6765 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
6766 strings.
6768 2002-10-22 Akim Demaille <akim@epita.fr>
6770 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

6817 longer required can still cause errors.
6818 Reported by Alexandre Duret-Lutz.
6820 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
6821 to frozen files in @ARGV, as @ARGV must remain being a list of

6823 (&files_to_options): New function.
6824 (&freeze): Use &error.
6825 (&up_to_date): If a file that was included according to the cache
6826 is no longer there, then the output is out dated.
6827 (&main): Don't even check whether a file is up to date is anyway
6828 --force is given.
6829 * tests/tools.at (autom4te cache): New.
6831 2002-10-16 Akim Demaille <akim@epita.fr>

6836 Factor some code.
6837 (&autoreconf): Report the directories we enter *and leave*, so
6838 that error messages can be easily located, and use GNU Make
6839 format, so that Emacs' compile mode understands us.
6840 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
6841 if some file was changed instead of `print'.
6842 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
6843 (&parse_args): Remove the dead options.

6876 file name to enable parallel executions.
6877 From Sam Varshavchik.
6879 2002-10-08 Akim Demaille <akim@epita.fr>
6881 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
6882 aclocal invocation, as Gettext macros might not be visible to
6883 aclocal.
6884 Instead of blindly running autopoint, scan configure.ac (not the
6885 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
6886 Reported by Paul D. Smith.
6888 2002-10-08 Paul Eggert <eggert@twinsun.com>
6890 Work around problems found when POSIXLY_CORRECT=1 is set.
6891 None of this seems to have anything to do with POSIX, really,
6892 but it's how Perl getopt works.
6893 * bin/autom4te.in (parse_args): Configure GetOpt with
6894 "permute", too.
6895 * doc/autoconf.texi (Invoking autom4te):
6896 --warning -> --warnings.
6897 * lib/autom4te.in: --warning -> --warnings.

6916 2002-09-28 Akim Demaille <akim@epita.fr>
6918 * tests/torture.at (Configuring subdirectories): Be robust to
6919 users who use config.site to require for a cache: in this case,
6920 the two last configure runs, using two different sets of
6921 arguments, trigger a legitimate error.
6923 2002-09-28 Akim Demaille <akim@epita.fr>
6925 * tests/m4sh.at (Functions Support, Functions and return Support):
6926 New.

6933 (autom4te): Specify that the sources are in the $srcdir.
6934 * doc/autoconf.texi (Installation Directory Variables): Adjust.

6939 (tm_zone): Move their rules to...
6940 * lib/autoconf/types.m4: here, using AN_ macros.
6941 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
6942 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)

6944 * lib/autoconf/programs.m4: here.
6945 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)

6949 2002-09-28 Akim Demaille <akim@epita.fr>
6951 * lib/autoconf/autoscan.m4: New file.
6952 * lib/autoconf/autoconf.m4: Include it.

6956 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
6957 (.m4.m4f): Don't pass --prepend-include, since that's done by
6958 tests/autom4te itself.

6960 (autoscan.list): New target --this file is no longer a source.
6961 (autoscan.pre): New file.
6963 2002-09-28 Akim Demaille <akim@epita.fr>
6965 * bin/autoscan.in (@kinds): Make them singular.
6966 Adjust all uses.
6967 (&init_tables): When --debug, report the list of rules to ease
6968 tracking changes in autoscan.list.
6969 * lib/autoscan/autoscan.list (function): Strip comments, sort.
6971 2002-09-28 Akim Demaille <akim@epita.fr>
6973 * lib/autoscan/functions, lib/autoscan/headers,
6974 * lib/autoscan/identifiers, lib/autoscan/makevars,
6975 * lib/autoscan/programs: Merge into...
6976 * lib/autoscan/autoscan.list: this.
6977 * bin/autoscan.in (&init_tables): Adjust.
6979 2002-09-28 Akim Demaille <akim@epita.fr>
6981 * lib/autoscan/functions, lib/autoscan/headers,
6982 * lib/autoscan/identifiers, lib/autoscan/makevars,
6983 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
6984 `functions' line is now prefixed with `function:'.
6985 * bin/autoscan.in (&init_tables): Adjust.
6987 2002-09-28 Akim Demaille <akim@epita.fr>
6989 From now on, autoscan files must always map a macro name to a
6990 word: there is no `default' macro for autoscan.
6992 * bin/autoscan.in (&init_tables): Reject entries with no macro at
6993 all.
6994 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
6995 explicit.
6997 2002-09-28 Akim Demaille <akim@epita.fr>
6999 * bin/autoscan.in (%c_keywords): Remove.
7000 (&used): Keep only track of the words we might be interested in.
7001 (&output_kind): It is no longer needed to look for non active
7002 checks.
7004 2002-09-27 Akim Demaille <akim@epita.fr>
7006 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

7011 2002-09-27 Akim Demaille <akim@epita.fr>
7013 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
7014 from /tmp.
7015 Thanks to Bill Moseley and Paul Eggert.
7016 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
7017 the tmpdir must be created.
7018 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
7019 dir be in the build tree, instead of $TMPDIR.
7021 2002-09-27 Akim Demaille <akim@epita.fr>
7023 * bin/autoscan.in: Improve the comments.
7024 (&parse_args): Drop obsolete undocumented options.
7025 (&output_kind): Output warnings.
7026 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

7033 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7035 2002-09-26 Akim Demaille <akim@epita.fr>
7037 Single suffix rules and seperated dependencies are not portable.
7039 * doc/autoconf.texi (Installation Directory Variables): Update.
7040 (Limitations of Make): Some about `Single Suffix Rules and
7041 Separated Dependencies'.
7042 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7043 (ifnames, autoscan, autom4te): Un-factor into several rules.
7045 2002-09-25 Paul Eggert <eggert@twinsun.com>
7047 * BUGS (Interoperability bugs): New section. Mention libtool
7048 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
7050 2002-09-24 Paul Eggert <eggert@twinsun.com>
7052 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
7053 make handles suffix-rules differently from GNU make.
7055 * bin/Makefile.am (SUFFIXES, .in): Remove.
7056 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
7057 Move the body of the old .in rule here.
7059 2002-09-16 Akim Demaille <akim@epita.fr>
7061 i960 compilers create `b.out' files by default.
7062 Reported by Ralf Corsepius.
7064 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
7065 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
7067 2002-09-13 Paul Eggert <eggert@twinsun.com>
7069 * doc/autoconf.texi (Particular Headers): Remove obsolete
7070 reference to `struct timezone' in the description of
7071 AC_HEADER_TIME.
7073 2002-09-13 Akim Demaille <akim@epita.fr>
7075 Version 2.54.
7077 * config/config.sub, config/config.guess: Update.
7078 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
7079 * Makefile.am: Adjust.
7081 2002-09-13 Akim Demaille <akim@epita.fr>
7083 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
7084 reading config.log when the compiler is rejected.
7085 Suggested by Guido Draheim.
7087 2002-09-13 Akim Demaille <akim@epita.fr>
7089 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
7090 (chdir_init) might hang when stat'ing mounted directories.
7091 Reported by Vance Shipley.
7093 2002-09-12 Akim Demaille <akim@epita.fr>
7095 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7096 the lists.
7098 2002-09-12 Akim Demaille <akim@epita.fr>
7100 * doc/autoconf.texi (Defining Symbols): Present two different
7101 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
7102 difference between 1 argument calls, and 2-3 argument calls.
7104 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
7106 * doc/autoconf.texi: Review grammar and punctuation.
7108 2002-09-11 Paul Eggert <eggert@twinsun.com>
7110 * doc/autoconf.texi: Fix minor formatting, spelling, and
7111 grammatical typos.
7112 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7113 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7114 is obsolescent.
7116 2002-09-11 Akim Demaille <akim@epita.fr>
7118 * doc/autoconf.texi (Questions): Rename as...
7119 (FAQ): this.
7120 (Defining Directories): New.
7122 2002-09-09 Akim Demaille <akim@epita.fr>
7124 * doc/autoconf.texi (Making testsuite Scripts): Update.
7125 Suggested by Nishio Futoshi.
7127 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
7129 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
7130 plain `@' is wanted.
7132 2002-09-09 Akim Demaille <akim@epita.fr>
7134 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7135 `duplicates', since the algorithm was too naive and could keep
7136 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7137 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7138 Reported by Ralf Corsepius.
7139 * tests/torture.at (Configuring subdirectories): Exercise these
7140 cases.
7142 2002-09-09 Akim Demaille <akim@epita.fr>
7144 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
7145 looking for a replacement file.
7146 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7147 directory is relative.
7148 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7149 directory definition.
7150 Reported by Andreas Schwab and Jim Meyering.
7152 2002-09-06 Akim Demaille <akim@epita.fr>
7154 * doc/autoconf.texi (Setting Output Variables): Clarify what
7155 precious variables are.
7156 Suggested by Pontus Skoeld.
7158 2002-09-05 Akim Demaille <akim@epita.fr>
7160 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7161 (ifnames, autoscan, autom4te): Since we don't only depend on
7162 configure.ac variables (such as VERSION etc.), but also on prefix
7163 and so forth, depend on Makefile, not configure.ac.
7164 Reported by Alexandre Duret-Lutz.
7165 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7167 2002-09-05 Kevin Ryde <user42@zip.com.au>
7169 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7170 doesn't seem to be confined to ia64, just say "some versions".
7172 2002-09-04 Akim Demaille <akim@epita.fr>
7174 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
7175 Automake 1.6c.
7176 * Makefile.am (maintainer-clean-local): Remove.
7177 (MAINTAINERCLEANFILES): Remove COPYING.
7179 2002-09-03 Paul Eggert <eggert@twinsun.com>
7181 * doc/autoconf.texi (Configuration Commands): Remove obsolete
7182 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
7183 Brinkmann.
7185 2002-09-03 Akim Demaille <akim@epita.fr>
7187 * configure.ac: Bump to 2.53d.
7188 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
7189 as of today, on Automake's team suggestion.
7191 2002-09-03 Akim Demaille <akim@epita.fr>
7193 Version 2.53c.
7195 2002-09-02 Akim Demaille <akim@epita.fr>
7197 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7198 SITE_MACRO_DIR.
7199 * configure.ac: Disable SITE_MACRO_DIR.
7201 2002-09-02 Jim Meyering <meyering@lucent.com>
7203 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7204 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7205 Also, tweak grammar: s/make sure to/be sure to/.
7207 2002-09-02 Paul Eggert <eggert@twinsun.com>
7209 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7210 directory names are generally preferable to physical names.
7212 2002-09-02 Akim Demaille <akim@epita.fr>
7214 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7215 Reported by Raja R. Harinath.
7216 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7217 * bin/autoupdate.in: Use error instead of die.
7219 2002-09-01 Paul Eggert <eggert@twinsun.com>
7221 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7222 ordinary shell concatenation rather than echo+tr+sed command that
7223 runs afoul of a long-line-related sed bug in Solaris 8.
7225 * bin/autoheader.in (parse_args): --warning -> --warnings.
7227 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7228 stdout, as traditional "ls" does.
7229 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7230 _AC_COMPILER_EXEEXT_O): Likewise.
7231 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7233 * bin/autoconf.as: Add --prepend-include option. This patch was
7234 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7235 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7237 * bin/autoconf.in, configure: Regenerate.
7239 * doc/autoconf.texi (Special Shell Variables): Mention
7240 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7242 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7243 MAILPATH and set PS1, PS2, PS4 to default values, to work
7244 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7245 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7246 the Autoconf documentation specifies; fall back to "unset" only if
7247 this fails. Use a shell for-loop for this rather than an m4 loop,
7248 to shorten the output script.
7250 2002-08-30 Paul Eggert <eggert@twinsun.com>
7252 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7253 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7254 for the CDPATH problem. Document PWD.
7255 (Limitations of Builtins): Document the problem that "cd $foo" and
7256 "ls $foo" may refer to different directories in shells conforming
7257 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7258 example, since the old example is now out of date.
7260 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7261 FOO" and "ls FOO" talk about different directories; this catches
7262 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7263 spaghetti.
7265 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7266 of rolling our own unset.
7267 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7268 in practice we needn't worry about CDPATH if unset doesn't work.
7270 * Makefile.in, aclocal.m4, bin/Makefile.in,
7271 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7272 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7273 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7274 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7275 tests/Makefile.in: Regenerate with Automake 1.6.3.
7277 * config/config.guess, config/config.sub, config/mkinstalldirs:
7278 Update.
7280 * configure: Regenerate with self.
7282 2002-08-30 Kevin Ryde <user42@zip.com.au>
7284 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7285 default output.
7287 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7289 * bin/autom4te.in (Request::load): Correctly test for "do" read
7290 failure.
7292 2002-08-29 Akim Demaille <akim@epita.fr>
7294 * lib/Autom4te/General.pm (&xqx): New.
7295 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7296 hand, which is not portable.
7297 (&error): New.
7298 * bin/autom4te.in: Use them.
7299 Use &error instead of die.
7300 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7301 Adjust.
7303 2002-08-17 Paul Eggert <eggert@twinsun.com>
7305 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7306 default list of compilers to try, since it was long ago superseded
7307 by the ksh fc builtin. Suggested by Steven G. Johnson.
7309 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7311 * doc/autoconf.texi (Invoking autom4te): End the option table,
7312 fixing a bug introduced by the previous patch.
7313 (Limitations of Make): Add a 'target lookup' subentry in the
7314 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7316 2002-07-29 Mark D. Roth <roth@feep.net>
7318 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7319 options and use $AUTOM4TE_PATH.
7320 * doc/autoconf.texi: Remove documentation of autom4te
7321 --include-envvar and --site-macro-subdir options and document
7322 use of $AUTOM4TE_PATH.
7323 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7324 arguments from each language section.
7326 2002-07-29 Paul Eggert <eggert@twinsun.com>
7328 * doc/install.texi: Include copyright symbol in copyright notice.
7330 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7331 Replace with:
7332 (AM_MAKEINFOFLAGS): New macro.
7333 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7334 * Makefile.am (INSTALL): Use the new macros.
7335 Use -o rather than --output, since "missing" does not grok --output.
7337 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7339 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7340 comments do not always work. Never trust the exit status of
7341 `make -k'.
7343 2002-07-24 Kevin Ryde <user42@zip.com.au>
7345 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7346 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7348 2002-07-23 Paul Eggert <eggert@twinsun.com>
7350 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7351 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7352 apparently treats PATH="nonexistent" as if it contained ".".
7353 Bug reported by Stefan `Sec' Zehl.
7355 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7357 * doc/autoconf.texi (Limitations of Make): Mention the special
7358 handling of the obj/ directory by BSD make.
7360 2002-07-20 Kevin Ryde <user42@zip.com.au>
7362 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
7363 backslashes.
7365 2002-07-19 Akim Demaille <akim@epita.fr>
7367 * doc/autoconf.texi (Function Portability): `exit'.
7368 (Programming in M4sh): Ethymology of M4sh.
7370 2002-07-19 Akim Demaille <akim@epita.fr>
7372 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
7374 2002-07-18 Akim Demaille <akim@epita.fr>
7376 Version 2.53b.
7378 2002-07-18 Akim Demaille <akim@epita.fr>
7380 * config/config.guess, config/config.sub: Update.
7382 2002-07-18 Akim Demaille <akim@epita.fr>
7384 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
7385 Automake's parts.
7387 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
7388 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
7389 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
7391 2002-07-18 Akim Demaille <akim@epita.fr>,
7392 Alexandre Duret-Lutz <duret_g@epita.fr>
7394 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
7395 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
7397 2002-07-17 Russ Allbery <rra@stanford.edu>
7399 * doc/autoconf.texi (Initializing configure): Clarify the
7400 description of the tarname default.
7402 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
7404 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
7405 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
7406 latter was not run.
7408 2002-07-17 Akim Demaille <akim@epita.fr>
7410 * lib/Autom4te/General.pm (find_file): Browse the directories in
7411 the order they are given.
7413 2002-07-17 Akim Demaille <akim@epita.fr>
7415 * tests/wrapsh.as, tests/wrappl.as: Merge into...
7416 * tests/wrapper.as: this.
7417 * tests/Makefile.am, configure.ac: Adjust.
7419 2002-07-17 Mark D. Roth <roth@feep.net>
7421 * configure.ac: Add --enable-site-macro-dir option.
7422 * bin/Makefile.am: Expand @SITE_MACRO_DIR@.
7423 * bin/autom4te.in: Add --prepend-include, --include-envvar, and

7479 2002-06-27 Paul Eggert <eggert@twinsun.com>
7481 * config/install-sh: Quote $src. Prefer || to test's -o option,
7482 as per "Limitations of Builtins".
7483 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
7484 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.

7514 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>

7517 of the cache should not depend on the name under which autom4te
7518 was installed.
7520 2002-06-07 Akim Demaille <akim@epita.fr>
7522 * tests/tools.at (autoconf: forbidden tokens, basic)

7526 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
7528 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
7529 _AC_LANG_PROGRAM_C_F77_HOOKS.
7531 2002-06-07 Akim Demaille <akim@epita.fr>

7537 AC_FUNC_FNMATCH_GNU.
7539 2002-06-07 Akim Demaille <akim@epita.fr>
7541 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
7542 Rosetta Stone for Unix.
7544 2002-06-07 Akim Demaille <akim@epita.fr>
7546 * bin/autom4te.in (warn_forbidden): When rejecting a token,
7547 suggest m4_pattern_allow.
7548 Suggested by Adam J. Richter.
7550 2002-06-07 Akim Demaille <akim@epita.fr>
7552 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize

7555 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

7568 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
7569 if ln doesn't work.

7609 version of Autoconf that is discussed.
7611 2002-05-22 Paul Eggert <eggert@twinsun.com>
7613 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7614 from the default list of compilers to try. Suggested by
7615 Kate Hedstrom.
7616 * NEWS: Document the above.
7617 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7619 2002-05-17 Paul Eggert <eggert@twinsun.com>
7621 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7622 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7623 This improves on an earlier suggestion by H. Peter Anvin.
7625 2002-05-16 Paul Eggert <eggert@twinsun.com>
7627 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7628 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7629 Both macros now accept an optional source-dir arg.
7630 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7632 * NEWS: Document this.
7633 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7635 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7636 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7637 not for GNU extensions; this undoes part of the 2000-11-03 change,
7638 reverting to 2.13-compatible behavior.
7639 Add new optional argument DIR.
7640 (AC_FUNC_FNMATCH_GNU): New macro.
7642 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7644 2002-05-08 Paul Eggert <eggert@twinsun.com>
7646 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7647 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7648 and it causes a 'test' syntax error if it fails.
7649 Bug reported by Stephen Gildea.
7651 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7652 If prototypes are supported, use them to check this at compile-time,
7653 instead of trying to check it at run-time. If we must do a run-time
7654 check, assume that setvbuf is standard when cross-compiling, as
7655 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7656 Bug reported by Paul D. Smith.
7658 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7659 argument specifying location of getloadavg.c. This removes a
7660 FIXME. This idea was taken from Jim Meyering's implementation in
7661 textutils.
7662 * doc/autoconf.texi (Particular Functions): Document this.
7663 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7664 that's what the code does; this fixes a bug reported by
7665 Paul D. Smith.
7667 2002-05-03 Akim Demaille <akim@epita.fr>
7669 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7670 autopoint instead of gettextize.
7671 ($uses_alocal): Rename as...
7672 ($uses_aclocal): this.
7673 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7674 Suggested by Bruno Haible.
7676 2002-05-03 Akim Demaille <akim@epita.fr>
7678 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7680 2002-04-29 Paul Eggert <eggert@twinsun.com>
7682 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7683 files to be 1 second older; just set them to be the same time.
7684 Also, sleep 1 second after the first aclocal, to work around
7685 problems with sub-second time stamps on the input files.
7687 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7689 * doc/autoconf.texi: Mention "set -e -x" lossage
7690 under node "Limitations of Builtins".
7692 2002-04-29 Akim Demaille <akim@epita.fr>
7694 * doc/install.texi: Better wording for setting variables when
7695 running configure.
7696 From Christian Cornelssen.
7698 2002-04-29 Akim Demaille <akim@epita.fr>
7700 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7701 of lack of $LINENO support, then the test will compare the $LINENO
7702 in testsuite vs. the lineno in the test file. This is wrong, of
7703 course.
7704 Be sure to protect it.
7705 Reported by Patrick Welche.
7707 2002-04-25 Akim Demaille <akim@epita.fr>
7709 * doc/autoconf.texi (Obsolete Macros): Typo.
7710 Reported by Vladimir Volovich.
7712 2002-04-25 Akim Demaille <akim@epita.fr>
7714 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7715 than some of the input files, hence, on the second run of aclocal,
7716 if some of its input are younger, make them older.
7717 Suggested by Paul Eggert.
7719 2002-04-25 Akim Demaille <akim@epita.fr>
7721 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
7722 Thanks to Paul Eggert.
7724 2002-04-25 Akim Demaille <akim@epita.fr>
7726 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7727 and ac_subst_vars be sh variables containing the list of
7728 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7729 DEFAULT diversion.
7730 (_AC_INIT_PREPARE): Use them to log them.
7731 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7732 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7733 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7734 _AC_SUBST_FILES and _AC_SUBST_VARS.
7735 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7737 2002-04-24 Akim Demaille <akim@epita.fr>
7739 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7740 autoheader, so that automake does not complain about a missing
7741 config.h.in that was to be created.
7743 2002-04-23 Akim Demaille <akim@epita.fr>
7745 * bin/autoheader.in (parse_args): --warning takes an argument.
7746 Fixes PR/220.
7748 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
7750 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

7769 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
7770 Fixes false failures on Darwin.

7795 Minor spelling and grammar fixes.
7797 * doc/autoconf.texi: Follow the outline suggested in the GNU
7798 Sample Texts sections of the Texinfo 4.2 manual. Most
7799 importantly, this makes sure that the copyright notices appear in
7800 all output formats. You probably need Texinfo 4.2 to generate
7801 the manual now.

7827 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
7829 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

7856 * lib/autotest/general.m4 (AT_INIT): Likewise.
7857 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

7861 Use this M4sh to generate Autoconf's shell scripts.
7863 * tests/wrapsh.as: New, precursor of wrapsh.in.

7906 Don't use the KILL diversion, as it kills spurious output, which
7907 results in failures being hidden.
7908 Use m4_defn where appropriate.
7909 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
7910 after the second argument.
7911 Use m4_defn.
7912 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
7913 syntax, as it is provided by M4sugar.
7914 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
7916 2002-04-03 Andreas Schwab <schwab@suse.de>
7918 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
7919 expanded if $# <= 2.
7921 * bin/autoreconf.in (autoreconf): Run automake after rerunning
7922 aclocal.
7924 2002-04-03 Akim Demaille <akim@epita.fr>
7926 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
7927 (_AC_COMPILER_EXEEXT_REJECT): New.
7928 Also recognize *.bb and *.bbg as compilation byproducts.
7929 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
7930 (_AC_COMPILER_OBJEXT): Use them.
7931 Fixes Debian #138666.
7933 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
7935 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
7937 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
7938 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
7939 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
7940 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
7941 (AC_C_CONST): Same.
7942 (AC_C_INLINE): Same.
7943 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
7944 * doc/autoconf.texi, NEWS: Document.
7945 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
7946 AC_C_CROSS.
7948 2002-04-02 Akim Demaille <akim@epita.fr>
7950 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
7951 _AS_MKDIR_P_PREPARE.
7953 2002-03-28 Kevin Ryde <user42@zip.com.au>
7955 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
7956 to avoid versions of HP C which don't allow that.
7958 2002-03-27 Paul Eggert <eggert@twinsun.com>
7960 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
7961 (AS_SHELL_SANITIZE): Invoke it.
7962 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
7964 2002-03-26 Akim Demaille <akim@epita.fr>
7966 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
7968 2002-03-26 Akim Demaille <akim@epita.fr>
7970 * doc/autoconf.texi (Introduction): The GNATS base moved.
7972 2002-03-25 Paul Eggert <eggert@twinsun.com>
7974 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
7975 as POSIX requires, as it doesn't work with Zsh.
7976 * doc/autoconf.texi (Assignments): Document the problem.
7978 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7980 * doc/autoconf.texi (Limitations of Make): Mention more issue
7981 about VPATH, overriding of macros in sub-makes, and handling of
7982 SHELL.
7984 2002-03-21 Paul Eggert <eggert@twinsun.com>
7986 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
7987 problem with here-document buffer boundaries.
7989 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
7990 when reinvoking the shell, to work around problems with installers
7991 who put strange things like "cd" commands in their environments.
7993 2002-03-19 Akim Demaille <akim@epita.fr>
7995 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
7996 From Aaron Ucko.
7998 2002-03-19 Akim Demaille <akim@epita.fr>
8000 * bin/autoscan.in (scan_file): Specify the location in `&used'
8001 invocations.
8002 From Nicolas Joly.
8004 2002-03-19 Akim Demaille <akim@epita.fr>
8006 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
8007 From Nishio Futoshi.
8009 2002-03-19 Akim Demaille <akim@epita.fr>
8011 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
8013 2002-03-18 Paul Eggert <eggert@twinsun.com>
8015 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8016 (Limitations of Usual Tools): Add mkdir section.
8018 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8019 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8020 back on AS_DIRNAME to compute prefixes otherwise; this is
8021 roughly what mkinstalldirs does. That way, we need not have
8022 our own filename disassembler. The old disassembler did not
8023 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8025 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8026 Create at_test_all by a series of assignments,
8027 not by a single assignment of a long string. The latter causes ksh
8028 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8029 presumably because of a buffer overrun.
8031 2002-03-14 Paul Eggert <eggert@twinsun.com>
8033 * lib/autotest/general.m4 (at_times_skip):
8034 Renamed from at_times. Now a boolean.
8035 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8036 says 'times: not found'.
8038 2002-03-14 Akim Demaille <akim@epita.fr>
8040 * bin/autoreconf.in (&study_gettextize): New.
8041 (&autoreconf): Handle newest gettextize.
8042 Rerun aclocal if needed.
8043 Suggested by Andreas Schwab.
8045 2002-03-13 Akim Demaille <akim@epita.fr>
8047 * doc/autoconf.texi (Special Shell Variables): More about IFS.
8049 2002-03-13 Akim Demaille <akim@epita.fr>
8051 * doc/autoconf.texi (Header Portability): New.
8052 Add information about stdint.h and inttypes.h from Paul Eggert.
8054 2002-03-13 Akim Demaille <akim@epita.fr>
8056 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
8057 -p'.
8058 From Bob Proulx.
8060 2002-03-12 Akim Demaille <akim@epita.fr>
8062 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
8063 m4_require.
8065 2002-03-11 Andreas Schwab <schwab@suse.de>
8067 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
8068 does not do it if --with-lispdir is given.
8070 2002-03-08 Akim Demaille <akim@epita.fr>
8072 Version 2.53.
8074 2002-03-08 Akim Demaille <akim@epita.fr>
8076 * doc/autoconf.texi (Subdirectories): Clarify that the
8077 subdirectory should exist.
8079 2002-03-08 Akim Demaille <akim@epita.fr>
8081 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
8083 2002-03-08 Akim Demaille <akim@epita.fr>
8085 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8086 aliases the actual variables, and modifications of the former
8087 affect the latter.
8089 2002-03-08 Akim Demaille <akim@epita.fr>
8091 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8092 because of C-c: have m4 output in tmp files, then mv them.
8094 2002-03-08 Akim Demaille <akim@epita.fr>
8096 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
8097 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
8098 * bin/ifnames.in: Copyright update.
8100 2002-03-08 Akim Demaille <akim@epita.fr>
8102 * doc/autoconf.texi (Invoking autom4te): New.
8104 2002-03-05 Akim Demaille <akim@epita.fr>
8106 * doc/autoconf.texi (Specifying Names): Clarification suggested by
8107 Kevin Ryde.
8109 2002-03-05 Akim Demaille <akim@epita.fr>
8111 Version 2.52i.
8113 2002-03-04 Akim Demaille <akim@epita.fr>
8115 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
8116 * lib/autoconf/general.m4 (AC_INIT): More informative error
8117 message for LIBOBJ.
8119 2002-03-04 Akim Demaille <akim@epita.fr>
8121 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
8122 parallel builds.
8124 2002-03-04 Akim Demaille <akim@epita.fr>
8126 * doc/autoconf.texi (Transforming Names): Equality between target
8127 and host is irrelevant.
8128 (Specifying Names, Canonicalizing): Remove all references to the
8129 backward compatibility hooks. Rather, collect them all into...
8130 (Hosts and Cross-Compilation): this new section.
8131 * doc/install.texi (System Type): Ditto.
8132 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8133 that `--host' implies cross-compilation.
8135 2002-03-04 Akim Demaille <akim@epita.fr>
8137 * doc/autoconf.texi (Evaluation Macros): New.
8138 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8139 useless.
8140 (_m4_foreach): Define the variant with immediate evaluation so
8141 that it contains exactly the items, not an expression which
8142 evaluation is the current item.
8143 (m4_re_string, m4_re_word): Don't over quote them.
8145 2002-03-04 Akim Demaille <akim@epita.fr>
8147 Instead of having stacking `shift's evaluated at the end, let
8148 `foreach' loops immediately evaluate them.
8150 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8151 $*. This is the n-th time I change my mind, but hopefully this is
8152 the last...
8153 (m4_lquote): New.
8154 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8155 efficient.
8156 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8157 it was only a hack for m4_text_wrap.
8158 (m4_car2): Remove, replaced by...
8159 (m4_cdr): New.
8160 (_m4_foreach): Adjust.
8161 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8162 m4_bpatsubst for clarification.
8164 2002-03-04 Akim Demaille <akim@epita.fr>
8166 * doc/autoconf.texi (Changequote is Evil): New.
8168 2002-03-03 Kevin Ryde <user42@zip.com.au>
8170 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
8171 on old systems like SunOS.
8173 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
8175 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8176 lib/autoconf/functions.m4, lib/autoconf/general.m4,

8184 message to be sent.
8186 2002-02-28 Kevin Ryde <user42@zip.com.au>

8190 2002-02-25 Akim Demaille <akim@epita.fr>
8192 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
8193 From Akinori Musha.
8195 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
8197 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
8198 translate \r\n to \n.
8200 2002-02-07 Akim Demaille <akim@epita.fr>
8202 Version 2.52h.
8204 2002-02-07 Akim Demaille <akim@epita.fr>
8206 Fix Autoconf PR/209.
8207 Also reported by Frank Denis.
8209 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
8211 2002-02-07 Akim Demaille <akim@epita.fr>
8213 Fix Autoconf PR/207:
8214 AC_PREFIX_PROGRAM fails with dashed program names
8216 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
8217 variable when looking for the prefix program.
8218 Now it also works for shell variables.
8220 2002-02-07 Akim Demaille <akim@epita.fr>
8222 * doc/autoconf.texi (Limitations of Builtins): More about
8223 case/esac.
8225 2002-02-06 Akim Demaille <akim@epita.fr>
8227 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
8228 case/esac, some shells don't support it.
8229 Reported by Zack Weinberg.
8230 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
8232 2002-02-06 Akim Demaille <akim@epita.fr>
8234 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
8235 sure not to introduce newlines in at_groups.
8236 * lib/autotest/Makefile.am (autotest.m4f): Typo.
8238 2002-02-06 Akim Demaille <akim@epita.fr>
8240 * tests/torture.at (Configuring subdirectories): Skip if aclocal
8241 is not available.
8243 2002-02-05 Paul Eggert <eggert@twinsun.com>
8245 * doc/autoconf.texi (Specific Compiler Characteristics):
8246 Describe HP-UX cc bug workaround more accurately.
8247 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
8248 not unsigned long.
8249 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
8250 cross-compilers, too. This undoes some of the most recent change
8251 to this file.
8253 2002-02-05 Akim Demaille <akim@epita.fr>
8255 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
8256 to make sure they are up to date when `check' is run.
8258 2002-02-05 Akim Demaille <akim@epita.fr>
8260 * doc/autoconf.texi (Making testsuite Scripts): Document
8261 package.m4.
8263 2002-02-05 Akim Demaille <akim@epita.fr>
8265 * lib/freeze.mk: New.
8267 2002-02-05 Akim Demaille <akim@epita.fr>
8269 Implement `autom4te --freeze'.
8271 * bin/autom4te.in (&freeze): New.
8272 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
8273 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
8275 2002-02-05 Akim Demaille <akim@epita.fr>
8277 * bin/autom4te.in (&parse_args): Implement `frozen files are
8278 optional are the sum of the previous files on the command line'.
8279 Also, pass `--reload-state=' on them, so...
8280 (handle_m4): don't.
8281 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8282 (M4sh): Rely on M4sugar.
8283 (Autotest, M4sh, M4sugar): Use frozen files.
8285 2002-01-31 Akim Demaille <akim@epita.fr>
8287 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
8288 * doc/autoconf.texi (Initializing configure): Adjust.
8290 2002-01-30 Akim Demaille <akim@epita.fr>
8292 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8293 alphanumeric to `-' instead of `_'.
8295 2002-01-30 Akim Demaille <akim@epita.fr>
8297 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8298 for plain code, the other for cross-compilation code. The latter
8299 is now run with GCC only.
8300 * doc/autoconf.texi (Compilers and Preprocessors): New.
8302 2002-01-30 Akim Demaille <akim@epita.fr>
8304 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
8305 values.
8306 * doc/autoconf.texi (Initializing configure): Explain how to
8307 change AC_INIT default values.
8309 2002-01-29 Akim Demaille <akim@epita.fr>
8311 * tests/torture.at (Configuring subdirectories): Use configure.in,
8312 so that aclocal 1.4 works.
8313 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8315 2002-01-28 Akim Demaille <akim@epita.fr>
8317 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8318 needs an argument.
8320 2002-01-28 Akim Demaille <akim@epita.fr>
8322 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8323 AUTOTEST_PATH *after* it was set.
8324 Don't put `.' in the PATH: the user should be precise and `./' if
8325 needed. In addition, given that the test suite does some `cd', if
8326 `.' is in the path, the `tested programs' sections will report
8327 programs found in the test suite's directory, while during the
8328 tests (performed in their own directory), these programs are no
8329 longer visible. In other words, the results is confusing and
8330 useless.
8331 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8333 2002-01-24 Akim Demaille <akim@epita.fr>
8335 Version 2.52g.
8337 2002-01-24 Akim Demaille <akim@epita.fr>
8339 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
8340 * doc/autoconf.texi: Finally add Akim as an author.
8342 2002-01-24 Akim Demaille <akim@epita.fr>
8344 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
8345 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
8346 Bourne. Use /bin/sh.
8347 From Andreas Buening.
8349 2002-01-24 Akim Demaille <akim@epita.fr>
8351 * config/config.guess, config/config.sub, config/texinfo.tex:
8352 Update from masters.

8359 * config/missing.m4, config/sanity.m4, config/select.m4,
8360 * config/strip.m4: Remove, to ease sync'ing with any version of
8361 Automake.
8363 2002-01-24 Akim Demaille <akim@epita.fr>
8365 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
8366 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
8367 Reported by Geir Ove Myhr.
8369 2002-01-21 Akim Demaille <akim@epita.fr>
8371 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
8373 2002-01-21 Akim Demaille <akim@epita.fr>
8375 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
8376 message on invalid options.
8377 * bin/autom4te.in (parse_args): Don't use
8378 Autoconf::General::getopt with non valid options.
8380 2002-01-17 Jim Meyering <meyering@lucent.com>
8382 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
8383 $ac_cv_exeext so we don't use an old, invalid, cached value.
8385 2002-01-11 Akim Demaille <akim@epita.fr>
8387 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
8388 Meyering.
8389 * doc/autoconf.texi (Function Portability): Document the strnlen
8390 limitation.
8391 (Particular Functions): Document AC_FUNC_STRNLEN.
8392 * lib/autoscan/functions: Adjust.
8394 2002-01-06 Akim Demaille <akim@epita.fr>
8396 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8397 package.m4, since is really depends upon configure.ac, not
8398 configure.
8399 * doc/autoconf.texi (testsuite Scripts): Adjust.
8400 * tests/Makefile.am (package.m4): New.
8401 EXTRA_DIST it since its a source.
8403 2002-01-06 Akim Demaille <akim@epita.fr>
8405 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8406 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8407 and PACKAGE_BUGREPORT from here...
8408 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8409 arguments.
8410 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8411 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8412 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8413 * tests/tools.at (autoheader): Adjust.
8414 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
8416 2002-01-06 Akim Demaille <akim@epita.fr>
8418 * bin/autoscan.in (scan_file): Use `&used'.
8420 2002-01-03 Akim Demaille <akim@epita.fr>
8422 * doc/autoconf.texi (Output): Improved wording regarding use of
8423 AC_OUTPUT.
8424 From Olly Betts.
8426 2001-12-18 Kevin Ryde <user42@zip.com.au>
8428 * doc/autoconf.texi (Function Portability): Add notes on sscanf
8429 sometimes needing writable input.
8431 2001-12-17 Jim Meyering <meyering@lucent.com>
8433 * doc/autoconf.texi (New Macros): Tweak wording.
8435 2001-12-14 Akim Demaille <akim@epita.fr>
8437 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8438 trailing files, don't apply `-rf' to files which might not be
8439 created by configure (core, core.*, and *.core), but just `rm -f'.
8440 Suggested by Jonathan Kamens.
8442 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8444 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8446 2001-12-14 Akim Demaille <akim@epita.fr>
8448 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8450 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
8452 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
8453 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
8454 abs_srcdir, top_srcpath to abs_top_srcdir.
8455 (_AC_OUTPUT_FILES): Adjust.
8456 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
8457 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
8458 * tests/wrappl.in, tests/wrapsh.in: Adjust.
8460 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8462 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
8463 C/Fortran linking on HP/UX, by extracting the Fortran library
8464 search path from the LPATH line in the $F77 -v output.
8466 2001-12-12 Kevin Ryde <user42@zip.com.au>
8468 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
8469 forbidden file descriptors table.
8471 2001-11-26 Akim Demaille <akim@epita.fr>
8473 * bin/autoscan.in (%c_keywords): Build it at top level.
8474 Map to 1 in order to simplify its uses.
8476 2001-11-26 Akim Demaille <akim@epita.fr>
8478 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8479 Remove $filepath, useless.
8480 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8481 variables, they are really part of the tokens.
8482 Split the input line on spaces and then look for tokens.
8483 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8484 because of `lex$U.$(OBJEXT)'.
8485 (&scan_files): Use "@list" instead of join.
8486 * doc/Makefile.am (CLEANFILES): Add *.fns.
8488 2001-11-26 Akim Demaille <akim@epita.fr>
8490 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
8491 Remove, replaced by...
8492 * tests/wrappl.in: Be common for all the Perl executables.
8493 In particular autoscan and autoheader want -I.
8494 * configure.ac: Adjust.
8495 * lib/autoscan/headers: errno.h is portable.
8497 2001-11-26 Akim Demaille <akim@epita.fr>
8499 * bin/autoscan.in (used): New.
8500 Use it.
8502 2001-11-26 Akim Demaille <akim@epita.fr>
8504 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
8505 directives.
8506 (&scan_sh_file): Remove a duplicate pattern.
8507 (&check_configure_ac): Use long options.
8508 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
8510 2001-11-26 Akim Demaille <akim@epita.fr>
8512 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
8513 Before, having a line containing the opening of a multi line
8514 comment made the whole line be ignored.
8516 2001-11-26 Akim Demaille <akim@epita.fr>
8518 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8519 (testsuite Scripts): Be one of its subsection.
8520 (Autotest Logs): New.
8522 2001-11-26 Akim Demaille <akim@epita.fr>
8524 Test groups are now run two directories deeper.
8526 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8527 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8528 at_top_builddir.
8529 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8530 top_srcdir, builddir and top_builddir.
8531 Use `at_*dir' relatively to the directory containing the
8532 suite, use `*dir' when relatively to the current group dir.
8534 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8536 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8537 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8538 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8539 spelling errors.
8541 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8543 * doc/autoconf.texi (Using System Type): Add an example of `case
8544 $host' usage so people quit using `case $target' everywhere.
8546 2001-11-22 Akim Demaille <akim@epita.fr>
8548 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8549 spotted by Jim Meyering.
8551 2001-11-16 Paul Eggert <eggert@twinsun.com>
8553 This patch implements a `long double' suggestion by Oliver Kiddle.
8555 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8556 static, to catch errors if the value isn't known at compile-time
8557 and the compiler supports dynamic arrays. Change its name from
8558 `_array_' to `test_array' to avoid potential name clashes.
8559 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8560 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8561 better than double. Catch a bug in GCC 2.95.2 x86.
8562 * doc/autoconf.texi (C Compiler): Document the above.
8563 * NEWS: Likewise.
8565 2001-11-13 Akim Demaille <akim@epita.fr>
8567 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8568 hand.
8569 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8571 2001-11-13 Akim Demaille <akim@epita.fr>
8573 * lib/autotest/general.m4 (AT_INIT): After having run the test
8574 group, go back to the initial directory, not to at_suite_dir.
8576 2001-11-13 Akim Demaille <akim@epita.fr>
8578 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8579 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8580 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8581 option.
8582 (AT_CHECK_CONFIGURE): Use absolute paths.
8583 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8584 The problem is still the old one: there is no means in M4 (that I
8585 know about) to create a defining macro, because there is no means
8586 to create `$1' etc., therefore, the defining macro ``swallows''
8587 all the arguments meant to the defined macro.
8589 2001-11-13 Akim Demaille <akim@epita.fr>
8591 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8592 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8593 configure.ac.
8594 * tests/aclocal.m4: Remove, as it is no longer used.
8596 2001-11-13 Akim Demaille <akim@epita.fr>
8598 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8599 variable names when referring to a single test group, or to
8600 `suite' when referring to the whole test suite.
8601 `at_last_test' is removed: m4 compute at_format itself.
8602 (at_stdout, at_stder1, at_stderr): New variables.
8603 (AT_CHECK): Use them.
8605 2001-11-13 Akim Demaille <akim@epita.fr>
8607 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8608 in PATH.
8609 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8610 Do it as soon as a test fails, don't wait till the end of the test
8611 suite.
8612 Don't remove $as_me.[0-9]*, since these files no longer exist.
8614 2001-11-13 Akim Demaille <akim@epita.fr>
8616 * tests/tools.at: Use absolute paths, since we are no longer run
8617 in place.
8619 2001-11-13 Akim Demaille <akim@epita.fr>
8621 Now that tests are running in their own private dir, there is no
8622 need to list the files to remove at the end of tests groups.
8624 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8625 (AT_data_files, at_data_files): Remove.
8626 (AT_CLEANUP, AT_DATA): Simplify.
8627 (AT_INIT): Adjust.
8628 Remove the group dir if !debug && !failed.
8629 * tests/atspecific.m4: Adjust.
8631 2001-11-13 Akim Demaille <akim@epita.fr>
8633 Start a new layout for Autotest: `testsuite' creates
8634 `testsuite.dir' in which the at-check-line etc. files are to be
8635 found, and `testsuite.dir/003' where the test group 3 is run.
8637 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8638 at_check_line_file, at_format, at_test_normalized, at_group_dir
8639 are new variables.
8640 Create the directories.
8641 Use absolute paths for at- files.
8642 (AT_CHECK): Adjust.
8644 2001-11-11 Michael Matz <matz@kde.org>
8646 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8647 (m4_car2): New.
8648 (m4_car): Properly quote arguments.
8650 2001-11-13 Akim Demaille <akim@epita.fr>
8652 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8653 with stricter rules on LIBOBJS.
8655 2001-11-12 Paul Eggert <eggert@twinsun.com>
8657 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8658 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8659 __PROTOTYPES too.
8661 2001-11-12 Akim Demaille <akim@epita.fr>
8663 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8665 2001-11-12 Akim Demaille <akim@epita.fr>
8667 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8668 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8669 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8670 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8671 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8672 specify to what the macro should be defined (typically to 1).
8674 2001-11-12 Akim Demaille <akim@epita.fr>
8676 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8677 From Jim Meyering.
8679 2001-11-12 Akim Demaille <akim@epita.fr>
8681 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8682 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8683 definition used by Automake where LEX is +/- "${missing} lex" and
8684 `missing' itself contains variables.
8686 2001-11-12 Akim Demaille <akim@epita.fr>
8688 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8689 Now that M4sh pushes BODY, the comments were output at the end of
8690 the test suites.
8692 2001-11-08 Akim Demaille <akim@epita.fr>
8694 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8695 that we can trace macros from aclocal.m4.
8696 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8697 obsoleted, and redirect to the former anyway.
8698 Reported by Ralf Corsepius.
8700 2001-11-08 Akim Demaille <akim@epita.fr>
8702 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8703 processed only if present.
8704 * tests/torture.at (Configuring subdirectories): Use autoreconf
8705 instead of successive calls to autoconf.
8706 Add a nonexistent subdirectory to exercise the patch above.
8707 Reported by Ralf Corsepius.
8709 2001-11-08 Kevin Ryde <user42@zip.com.au>
8711 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8712 doesn't accept .S files.
8714 2001-11-07 Akim Demaille <akim@epita.fr>
8716 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
8717 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
8718 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
8719 * bin/autom4te.in (warn_forbidden): New.
8720 (handle_output): Use it.
8721 Read m4_pattern_forbid with messages.
8723 2001-11-05 Akim Demaille <akim@epita.fr>
8725 * bin/autom4te.in (--normalize): Remove.
8726 * lib/autom4te.in: Adjust.
8728 2001-11-05 Akim Demaille <akim@epita.fr>
8730 * tests/Makefile.am (testsuite): Rename this target as...
8731 ($(TESTSUITE)): this.
8732 From Nicolas Joly.
8734 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8736 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
8737 the --prefix option, also remove it's argument.
8739 2001-11-05 Akim Demaille <akim@epita.fr>
8741 * doc/autoconf.texi (testsuite Invocation): Update.
8742 (Writing testsuite.at): Update.
8744 2001-11-03 Akim Demaille <akim@epita.fr>
8746 * doc/autoconf.texi: s/@code/@command/ where appropriate.
8748 2001-11-03 Akim Demaille <akim@epita.fr>
8750 * lib/Autom4te/General.pm: (&catfile, &canonfile)
8751 (&file_name_is_absolute): New, wrappers around routines from
8752 File::Spec.
8753 Use and export them.
8754 (&find_configure_ac): Optionally take a directory where to look at.
8755 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8756 the arguments.
8757 Default @ARGV to `.', not find_configure_ac.
8758 (&autoreconf): Argument is a directory.
8759 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8760 * doc/autoconf.texi (autoreconf Invocation): Update.
8762 2001-11-03 Akim Demaille <akim@epita.fr>
8764 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8765 (@export_forward_subs): New.
8766 Add basename, dirname, and fileparse.
8767 (@EXPORT): Adjust.
8768 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8769 Don't look for aclocal flags if we already know aclocal is not
8770 used.
8771 Move aclocal.m4t only if it exists.
8772 Reported by Ezra Peisach.
8774 2001-11-03 Akim Demaille <akim@epita.fr>
8776 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8777 passed on command line, defaulting to ./configure.ac if present.
8778 (&maybe_autoreconf, File::Find): Remove, unused.
8779 (&autoreconf): If autoconf is not used, don't try to trace.
8781 2001-11-02 Akim Demaille <akim@epita.fr>
8783 * configure.ac: Bump to 2.52g.
8785 2001-11-02 Akim Demaille <akim@epita.fr>
8787 Version 2.52f.
8789 2001-11-02 Akim Demaille <akim@epita.fr>
8791 * config/config.guess, config/config.sub, doc/standards.texi:
8792 * config/lispdir.m4: Update from masters.
8793 * configure.ac: Bump to 2.52f.
8795 2001-11-02 Akim Demaille <akim@epita.fr>
8797 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8798 Don't run aclocal when aclocal.m4 is not from aclocal.
8799 From Ezra Peisach.
8800 Don't run libtoolize and gettextize if --install is not given.
8802 2001-11-01 Paul Eggert <eggert@twinsun.com>
8804 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8805 be invoked before _AS_LINENO_PREPARE.
8806 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8807 than character ranges.
8809 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8810 invoking AS_BASENAME. Set the locale variables to 'C' if
8811 possible, as POSIX requires this to get the traditional
8812 behavior.
8813 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8815 2001-10-31 Paul Eggert <eggert@twinsun.com>
8817 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8818 with {}, as that triggers a bug in Bash 2.05.
8820 (_AS_LINENO_PREPARE): Use Sed rather than
8821 Awk. Fix the sed prepass to work even if there are multiple
8822 instances of $LINENO on the same line. Do not substitute for
8823 other variables like $LINENOT. Do not check file dates; such a
8824 check is unreliable on sufficiently fast machines, and removing
8825 the check makes the code simpler and more reliable. Check for
8826 output and chmod failures.
8828 * doc/autoconf.texi (Special Shell Variables): Document
8829 the above.
8831 2001-10-31 Akim Demaille <akim@epita.fr>
8833 * tests/Makefile.am (atconfig): Remove this target, Automake
8834 handles it now.
8836 2001-10-31 Akim Demaille <akim@epita.fr>
8838 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
8839 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
8840 provided, while it is optional.
8841 * configure.ac: Adjust.
8843 2001-10-26 Paul Eggert <eggert@twinsun.com>
8845 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8846 lib/Autom4te/Struct.pm:
8847 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8848 with 5.005_02.
8850 * doc/autoconf.texi (Special Shell Variables): Document some
8851 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8853 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8854 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
8855 eval $LINENO is not portable in practice.
8857 2001-10-24 Akim Demaille <akim@epita.fr>
8859 * lib/Autom4te/General.pm (backname): New.
8861 2001-10-24 Akim Demaille <akim@epita.fr>
8863 * m4/: Remove, merged into...
8864 * config/: here.
8866 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
8868 * doc/autoconf.texi (Shellology): Mention the problems with bash
8869 2.05's use of ANSI quoting in its `set' builtin.
8871 2001-10-22 Paul Eggert <eggert@twinsun.com>
8873 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
8874 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8875 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8876 POSIX decided to standardize on the int flavor of strerror_r.
8877 Always do char* test, as there's no reason not to.
8878 Assign to a char* var, to catch strerror_r that returns int*.
8880 * doc/autoconf.texi (Particular Functions):
8881 Document the above changes. Also, document the fact that
8882 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
8884 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
8886 2001-10-20 Akim Demaille <akim@epita.fr>
8888 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
8889 the executable was missing from the log.
8891 2001-10-20 Akim Demaille <akim@epita.fr>
8893 * lib/Autom4te/General.pm (&update_file): If destination is
8894 unchanged, remove the source.
8895 (&up_to_date_p): Don't be verbose, be debug.
8896 * bin/autoreconf.in: No longer support --m4dir.
8897 (&autoreconf): Display the full path of the configure.ac we are
8898 studying.
8899 Trace it only once.
8900 Be sure to honor --force with gettextize.
8901 Always run aclocal.
8902 * doc/autoconf.texi: Adjust.

9222 * tests/fortran.at (GNU Fortran 77): there.
9223 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9224 AC_TRY_RUN is about compilation, not shell commands.

9371 * doc/autoconf.texi (File System Conventions): Clarify the use of
9372 PATH_SEPARATOR.
9373 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
9374 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9375 be used instead of ':'.
9376 * lib/autotest/general.m4: Replace occurrences of ':' in
9377 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
9379 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9381 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
9382 arguments. Fixed a typo.
9384 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9386 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
9387 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
9389 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9391 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
9392 * bin/autoupdate.in: Ditto.
9393 * bin/autoheader.in: Reworded a few comments.
9394 * bin/autoconf.in: Reworded help text for a few options.
9395 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
9396 * bin/autoscan.in, bin/autoupdate.in: Ditto.
9398 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9400 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
9401 already have $file). Set output files to binary mode (helps avoid
9402 CR issues on DOSish systems).
9404 2001-09-19 Akim Demaille <akim@epita.fr>
9406 * lib/autotest/general.m4: Englishoes.
9407 From Tim Van Holder and Alexey Mahotkin.
9409 2001-09-18 Paul Eggert <eggert@twinsun.com>
9411 * doc/autoconf.texi (Common Shell Constructs): New node,
9412 documenting AS_DIRNAME.
9413 (Limitations of Usual Tools): Refer to it when discussing dirname.
9414 Also, update discussion of POSIX standard to reflect latest draft.
9416 * lib/autoconf/c.m4:
9417 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9419 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9420 Do not pass a first argument with leading '-'
9421 to expr, by parenthesizing initial integers that might be negative.
9423 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9424 now merely checks whether it is an error to pass an argument
9425 to getpgrp.
9427 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9428 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9429 whether it is a (compile-time) error to pass an argument to
9430 getpgrp. This simpler test supports the revised documentation,
9431 and is all that AC_FUNC_GETPGRP's users really need.
9433 2001-09-18 Akim Demaille <akim@epita.fr>
9435 * doc/autoconf.texi (Limitations of Make) <$<>: New.
9437 2001-09-18 Akim Demaille <akim@epita.fr>

9441 * lib/autotest/general.m4 (AT_INIT): Adjust.
9443 2001-09-18 Paul Wagland <paul@wagland.net>
9445 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9446 correctly.
9447 Add test for AS_BASENAME.
9448 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9449 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9450 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9451 * tests/base.at: Fixed the expected responses. The old ones were
9452 one line out...
9453 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9454 the documentation claims it should (and how it behaved in 2.13).
9456 2001-09-18 Akim Demaille <akim@epita.fr>
9458 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9459 the AC_CONFIG_COMMANDS invocation.
9460 This also solves the name clash problems.
9461 Don't set the package's ID.
9462 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9463 No longer to be shipped.
9464 (version.in): Remove.
9465 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
9466 * lib/autoconf/status.m4: Adjust.
9467 Use `m4_PACKAGE_STRING'.
9468 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9469 the only optional argument is the name of the test suite.
9470 Expect `package.m4' to define the package signature.
9471 * lib/autom4te.in (Autotest): Add `package.m4?'.
9472 * tests/Makefile.am (package.m4): New.
9473 * tests/suite.at: ifnames is a victim.
9475 2001-09-18 Akim Demaille <akim@epita.fr>
9477 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9478 AC_LIBSOURCE, AC_CONFIG_FILES.
9479 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
9480 program version string doesn't match the package's.
9481 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9482 after `(cached)'.
9484 2001-09-17 Paul Eggert <eggert@twinsun.com>
9486 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9487 Allow expression to return any value that can fit into unsigned long
9488 (not int, as before). Check for output errors.
9490 2001-09-17 Bruno Haible <haible@ilog.fr>
9492 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9493 Always include <stdio.h> and <stdlib.h>. Evaluate
9494 the expression in an extra function before these includes. Call
9495 fprintf "%d" only after ensuring the argument is of type 'int'.
9496 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9498 2001-09-17 Paul Eggert <eggert@twinsun.com>
9500 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9501 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9502 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9503 when they don't exist.
9505 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9506 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9507 need it.
9509 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9510 version with the version used by fileutils 4.1, except use
9511 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
9512 we don't need it.
9514 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
9516 2001-09-13 Akim Demaille <akim@epita.fr>
9518 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
9519 _first_.
9520 Reported by Gerrit P. Haase.
9522 2001-09-13 Akim Demaille <akim@epita.fr>
9524 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

9539 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
9540 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
9541 Likewise.
9542 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
9543 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
9544 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
9545 AT_tests_all for consistency.
9546 Set at_victims.
9547 (AT_VICTIMS): Similar to AT_KEYWORDS.
9548 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
9550 2001-09-13 Akim Demaille <akim@epita.fr>
9552 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
9554 2001-09-13 Akim Demaille <akim@epita.fr>
9556 * lib/autotest/general.m4 (AT_INIT): Create and remove
9557 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
9558 test suites can cohabit.
9560 2001-09-13 Akim Demaille <akim@epita.fr>
9562 * tests/mktests.sh: Don't output banners for empty test files.
9564 2001-09-13 Akim Demaille <akim@epita.fr>
9566 Test suites can be run independently of configure.

9614 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
9615 PATH_SEPARATOR, let M4sh compute it.

9617 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

9630 2001-09-07 Akim Demaille <akim@epita.fr>

9634 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
9635 related variables into `at_package_*'.

9645 Move toward possibly stand-alone test suites.
9647 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
9648 in addition, it introduces useless differences in logs.

9650 Adjust PATH computation.
9651 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

9662 From Uwe Seimet.

9668 2001-09-05 Akim Demaille <akim@epita.fr>
9670 Be ready to handle filenames as stupid as `dnl.at', for if even
9671 the maintainer is dumb enough to do that...
9673 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9674 excellence in M4 quotation: consider `__file__' is active.
9676 And BTW, when invoking m4, pass the --include in the right order:
9677 the wrong one.
9679 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

9707 New, extracted from main.
9708 Use IO::File wherever possible.
9709 (input.m4): Be constant, use -I instead of hard coding $tmp.

9714 2001-08-31 Akim Demaille <akim@epita.fr>

9742 (testsuite Scripts): There is no such thing as `atconfig.in'.

9745 2001-08-31 Akim Demaille <akim@epita.fr>
9747 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9748 inverse order.

9753 to m4sugar was lacking!
9755 2001-08-31 Akim Demaille <akim@epita.fr>
9757 * man/Makefile.am (.x.1): We really have to pass
9758 autom4te_perllibdir.
9760 2001-08-31 Akim Demaille <akim@epita.fr>
9762 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
9763 debug scripts, in particular passing explicitly listed tests to
9764 run is stupid.
9766 2001-08-31 Akim Demaille <akim@epita.fr>
9768 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9769 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9770 Use directly autom4te, not autoconf.

9794 `print $out' doesn't print `$_' but `$out'.
9795 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9796 (autoheader): Pass --force since the test suite goes too fast for
9797 the time stamps.
9798 Adjust to the new autoheader messages.
9800 2001-08-31 Akim Demaille <akim@epita.fr>

9826 Forward autom4te's options instead of interpreting them.

9837 * bin/autom4te.in (&find_file): Support `FILE?' standing for

9839 Use -e, not -f, since /dev/null for instance is OK.
9840 (&parse_args): Adjust.
9841 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
9843 2001-08-31 Akim Demaille <akim@epita.fr>
9845 * configure.ac: Also find tested executables in bin.
9846 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
9847 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
9848 installed peer executables, only PATH is allowed to resolve it.
9849 Pass `autoconf_dir' via options, not via invisible envvars.
9850 * lib/Autom4te/General.pm (&find_peer): Remove.
9851 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
9852 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
9853 * man/Makefile.am: Let help2man rely on PATH instead of trying to
9854 find the executables for it.
9855 * tests/Makefile.am: Major cleanup. Too lazy to document...
9856 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9857 We only need PERL.
9858 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9859 indeed related to running the test suite, while passing
9860 --autoconf-dir and others is related to running non installed
9861 Autoconf executables. So don't do that, leave it to...
9862 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
9863 * tests/autoscan: New.
9864 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
9865 refer to library files: rely on --language.

9880 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
9881 Suggested by Paul Eggert.
9883 2001-08-29 Akim Demaille <akim@epita.fr>
9885 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
9886 download in a tmp dir.
9888 2001-08-29 Akim Demaille <akim@epita.fr>
9890 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

9913 (at-devnull): Rename as...
9914 (AT-devnull): this.
9915 (--clean): Remove AT-* files too.

9951 * lib/autotest/general.m4 (AT_INIT): Log the command line.
9952 Support `VAR=VAL' as arguments.

9974 readable.

9977 available in commands.

9983 (Initializing configure): this new node.
9985 2001-08-27 Akim Demaille <akim@epita.fr>

10045 * m4/strip.m4: New.

10060 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
10061 the name of the directory they're in, instead of the filename,
10062 since version.m4 is now in m4sugar, but m4_acversion must not be
10063 classified as an Autoconf macro.
10064 ($input_m4): Don't qualify the path to m4sugar.
10065 Rather, pass autoconf_dir to m4.
10066 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

10150 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
10151 * NEWS, README, README-alpha, TODO, tests/README: This package is
10152 `Autoconf', not `autoconf' (the executable).
10154 2001-08-20 Akim Demaille <akim@epita.fr>
10156 Info readers seem to need `Index' in the index node title :(

10159 simplified index node names.
10161 2001-08-20 Akim Demaille <akim@epita.fr>
10163 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the

10171 (Examining Syntax) <AC_TRY_COMPILE>

10203 2001-08-20 Akim Demaille <akim@epita.fr>
10205 Huh!?!?! There are still some user EOF tags used, which prevents
10206 their use in AC_CONFIG_COMMANDS for instance...
10208 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
10209 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
10210 `_CSEOF', or `_ATEOF', as appropriate.

10270 2001-08-17 Akim Demaille <akim@epita.fr>
10272 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

10345 (cvs-dist): depends upon it.
10347 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
10349 * tests/Makefile.am: Use a clean-local rule to remove
10350 autom4te.cache (it's a directory, not a file.
10351 * Makefile.am: Ditto (but maintainer-clean-local).
10353 2001-08-15 Akim Demaille <akim@epita.fr>
10355 * bin/autom4te.in (@m4_warning): New.
10356 (&handle_m4): Use it.
10357 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
10358 warnings are issued at each run.
10359 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
10360 is in the src tree.
10362 2001-08-15 Akim Demaille <akim@epita.fr>

10365 don't waste time running `autoupdate --version' works.
10366 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
10368 2001-08-13 Akim Demaille <akim@epita.fr>

10427 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10429 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10430 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10431 * doc/autoconf.texi (C Compiler Characteristics): Update
10432 documentation for AC_C_BIGENDIAN.
10434 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10436 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10437 magic values from an object file when cross-compiling.
10438 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10440 2001-08-10 Akim Demaille <akim@epita.fr>
10442 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10443 effects.
10444 Suggested by Russ Allbery.
10446 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10448 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10449 current $prefix to the sub-configures.
10451 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10453 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10454 extension (needed on BeOS). Reported by Guido van Rossum.
10456 2001-08-09 Akim Demaille <akim@epita.fr>
10458 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10460 2001-08-07 Akim Demaille <akim@epita.fr>
10462 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10463 removed.
10464 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10465 No need to remove the files before and after the each test, before
10466 each test and at the end of the suite is enough.
10467 Display only the children `times', not the shell's.
10468 If the test failed or was skipped, at-times is not available.
10470 2001-08-07 Akim Demaille <akim@epita.fr>
10472 Always produce testsuite.log, including when there are no
10473 failures. This helps getting information on skipped tests, and
10474 duration of the tests. Err, implement the latter btw.
10476 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10477 Dump information on the first run of each test.
10478 (AT_CLEANUP): Create `at-times' containing the duration of the
10479 test group.
10481 2001-08-07 Akim Demaille <akim@epita.fr>
10483 The use of `dumpstat' revealed that `len' was used although it
10484 should not. m4_text_wrap was using it, but in the Autoconf world
10485 where it is legal. Hence (i) test M4sh in its own world, not
10486 Autoconf's, and (ii), ahem, fix the bug :)
10488 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10489 does not like `' instead of [].
10490 (AT_INIT): Forbid `^_?AT_'.
10491 And don't output such tokens.
10492 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10493 `script.as', and `autom4te.cache'.
10494 Remove `empty' and `macro' which are no longer used.
10495 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10496 * tests/m4sugar.at: Use it.
10497 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10499 2001-08-07 Akim Demaille <akim@epita.fr>
10501 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10503 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10505 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10507 2001-08-04 Akim Demaille <akim@epita.fr>
10509 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10510 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10511 AC_TRY_LINK.
10512 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10513 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10514 (AC_F77_MAIN): Likewise.
10516 2001-08-04 Akim Demaille <akim@epita.fr>
10518 Don't rely on M4sugar outputting the patterns in files, since we
10519 might process the output _without_ running m4, hence without these
10520 files.
10522 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10523 * bin/autom4te.in (@Request::includes): Remove, unused.
10524 (@Request::source): Rename as...
10525 (@Request::input): this.
10526 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10527 (&handle_output): Fetch the patterns from the traces.
10528 `$forbidden' and `$allowed' are constant: use m//o.
10529 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10530 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
10532 2001-08-04 Akim Demaille <akim@epita.fr>
10534 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10535 autoconf', i.e., in addition to caching traces, cache the output.
10537 * bin/autom4te.in (Request::cache): Rename as...
10538 (Request::id): this.
10539 ($cache, $icache, $tcache, $ocache): New.
10540 (&handle_m4): Save M4 output in the cache instead of $tmp.
10541 (&handle_output): Adjust.
10542 (&up_to_date_p): Check that the output cache is up to date too.
10543 (top level): Run `&handle_m4' iff force or the cache is invalid.
10544 Run `&handle_output' if the output cache is more recent.
10546 2001-08-04 Akim Demaille <akim@epita.fr>
10548 * bin/autom4te.in ($force): New.
10549 (&parse_args, &print_usage): -f, --force is a new option.
10550 (&handle_output): CPP directives might have spaces after `#'.
10551 (&parse_args): The first file only can be frozen.
10553 2001-08-04 Akim Demaille <akim@epita.fr>
10555 Don't let autom4te compute the `include' traces several times:
10556 first check that the trace cache file is up to date, and then
10557 compare its timestamp with that of the output.
10559 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
10560 the preamble. Don't require 5.005 as Autom4te::General does it,
10561 and better yet (use `use', not `require'!).
10562 * lib/Autom4te/Struct.pm: Rename the last occurrences of
10563 Class::Struct as Autom4te::Struct.
10564 * lib/Autom4te/General.pm (File::stat): Use it.
10565 (&mtime): New, export it.
10566 * bin/autom4te.in: Use it.
10567 Declare `$req' is invalid if it is outdated.
10568 Don't declare it valid before saving it if something went wrong.
10570 2001-08-04 Akim Demaille <akim@epita.fr>
10572 Autom4te shall not encode Autoconf data, and preselecting traces
10573 must be proposed to the users.
10575 * bin/autom4te.in (@required_trace): Remove.
10576 (@preselect): New.
10577 (&parse_args, &print_usage): -p, --preselect is a new option.
10578 (&up_to_date_p): Adjust.
10579 * bin/autoconf.in: Preselect some Autoconf macros.
10581 2001-08-04 Akim Demaille <akim@epita.fr>
10583 * tests/tools.at (autoconf --trace: user macros): Check traces on
10584 macros invoked without arguments, and macros invoked with multiple
10585 lines arguments.
10587 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
10589 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
10590 arguments.
10592 2001-08-03 Akim Demaille <akim@epita.fr>
10594 * bin/autoconf.in ($@): Work around the usual sh bug.
10595 From Nicolas Joly.
10597 2001-08-03 Akim Demaille <akim@epita.fr>
10599 Clean up the handling of the M4 builtins tracing exception.
10601 * bin/autom4te.in (Request::request): Don't complete M4 builtins
10602 trace requests.
10603 (@m4_builtins): Rename as...
10604 (@m4_builtin): this.
10605 (%m4_builtin_alternate_name): New.
10606 (&parse_args): Complete the trace requests with alternate names.
10607 (&handle_traces): Hence no longer do it here.
10608 (&trace_requests): Remove, unused.
10610 2001-08-03 Akim Demaille <akim@epita.fr>
10612 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
10613 m4_if, and m4_wrap.
10615 2001-08-03 Akim Demaille <akim@epita.fr>
10617 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
10618 (m4_divert_pop): Dump the whole diversion stack when a diversion
10619 mismatch happens.
10620 * bin/autom4te.in (&handle_output): Remember of the first
10621 occurrence of a possibly undefined macro, not the last.
10622 Complain about the possibly undefined macros in the same order as
10623 the appear in the output.
10624 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
10625 * tests/tools.at (autoconf: forbidden tokens, basic)
10626 (autoconf: forbidden tokens, exceptions): No longer sort
10627 autoconf's stderr, as it is now deterministic.
10628 Check that `dnl' is caught.
10630 2001-08-01 Akim Demaille <akim@epita.fr>
10632 * configure.ac: Bump to 2.52c.
10634 2001-08-01 Akim Demaille <akim@epita.fr>

10644 2001-08-01 Akim Demaille <akim@epita.fr>
10646 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
10647 `die'.
10648 (&END): New.
10649 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
10650 `END', as `Autom4te::General::END' will be triggered.
10651 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
10652 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

11044 compiler, not the preprocessor.
11045 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use

11047 the right thing.
11048 * Makefile.am (.m4.m4f): Emphasize M4 error messages and fail
11049 earlier if there are.
11051 2001-07-03 Akim Demaille <akim@epita.fr>

11078 fixing link failures for e.g. AC_F77_WRAPPERS on NetBSD.
11080 * aclang.m4 (AC_F77_DUMMY_MAIN): New macro to detect whether a
11081 dummy alternate main is required even if the user provides her own
11082 'main'.
11083 (AC_F77_MAIN): New macro to detect whether it is possible to
11084 provide an alternate 'main' function name, using the 'main' from
11085 the Fortran libraries.
11086 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
11087 cross-language link tests can be performed successfully.
11088 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
11089 after $LIBS, for consistency; this should be the general rule since
11090 the user may want to link to Fortran libraries that require $FLIBS.
11091 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.
11093 2001-06-29 Pavel Roskin <proski@gnu.org>
11095 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
11096 at-stdout and at-stderr instead of removing the newline
11097 from the echo output, which is not guaranteed to work.
11099 2001-06-28 Jens Petersen <petersen@redhat.com>
11101 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to

11145 Suggested by Mo DeJong.
11147 2001-06-24 Akim Demaille <akim@epita.fr>

11160 * tests/torture.at (AC_ARG_VAR): Make it a single test instead of
11161 three as failures are unlikely, and speed matters.
11163 2001-06-23 Akim Demaille <akim@epita.fr>
11165 * doc/autoconf.texi (Redefined M4 Macros): New.
11167 2001-06-23 Akim Demaille <akim@epita.fr>
11169 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider
11170 inttypes.h is missing if it conflicts with sys/types.h, as on IRIX
11171 5.3.

11175 * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): Defer parsing of
11176 config.status targets to after the evaluation of the INIT-CMDS.
11177 Double quote config.status targets (used to be single quoted).
11179 2001-06-23 Akim Demaille <akim@epita.fr>
11181 * tests/torture.at (CONFIG_FILES, HEADERS, LINKS and COMMANDS):

11204 * tests/torture.at (AC_ARG_VAR): Adjust.
11206 2001-06-21 Akim Demaille <akim@epita.fr>
11208 ./configure --program-suffix=foo produces `transform=s,$$,foo,;',
11209 but some sed choke on multiple `;', and other tools (e.g.,
