1 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
4 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
5 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
7 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
10 `CEOF$ac_eof' special marker, the awk script cannot contain a
11 line matching `^CEOF', so this is not needed any more.
12 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
13 special marker in the test.
15 2006-12-06 Stepan Kasal <kasal@ucw.cz>
17 * tests/tools.at (autom4te preselections): Use `find -newer';
18 remove one of the sleeps.
20 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
21 more readable, using ...
22 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
24 * doc/autoconf.texi (autoheader Invocation): Do not double-
25 quote the parameter of `AH_BOTTOM' in the example.
27 2006-12-05 Stepan Kasal <kasal@ucw.cz>
29 * doc/autoconf.texi (Configuration Headers): Remove the
30 example with multiple input files.
31 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
32 multiple input files.
34 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
36 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
37 creating the awk substitution script, handle one input line at a
38 time, so that the maximum length of a substituted (multi-line)
39 value is not limited by the size of the sed pattern space.
40 The trade-off is a slightly repetitive sed script.
41 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
42 can only have up to 7 characters, due to Solaris 10 /bin/sed.
43 * tests/torture.at (Substitute a 2000-byte string): Increase the
44 test with several long lines, they should not be caught by sed
45 limits any more.
47 * tests/tools.at (autom4te preselections): New test, to flag
48 entries missing from autom4te.cfg.
49 Report by David Byron <dbyron@hheld.com>.
51 * tests/torture.at (Substitute a 2000-byte string): Actually use
52 AC_PROG_AWK, so the last change works as intended.
53 (Substitute and define special characters): Likewise.
54 (Substitute a newline): Likewise.
56 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
57 instead of `awk' consistently.
58 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
59 * tests/torture.at (Torturing config.status): Test both the
60 result of AC_PROG_AWK and plain awk.
61 (Substitute a 2000-byte string): Likewise.
62 (Substitute and define special characters): Likewise.
63 (Substitute a newline): Likewise.
65 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
67 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
68 can be assigned to a function pointer. Problem reported by
69 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
70 part of a patch by Ralf Wildenhues in that same bug report.
72 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
74 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
75 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
77 2006-12-01 Eric Blake <ebb9@byu.net>
79 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
80 cross-compiling from cygwin to mingw.
81 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
82 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
83 to lib/autoconf/c.m4.
85 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
87 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
88 string for more reliable failure. Wrap the entire test that
89 causes the broken Solaris printf to dump core, in a subshell,
90 so the segmentation fault message is reliably suppressed.
91 Fix shell expansion errors by using /usr/ucb/echo always;
92 avoid an error on systems without it by another subshell.
93 Avoid m4 expansion of `$1'. Set the zeroth argument of the
94 subshell-$as_echo to `as_echo', for better error message.
96 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
98 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
99 `BASH_SOURCE' contain a newline, set them to empty, as they may
100 not be unset.
102 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
104 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
105 years and is too hard to maintain now. The last straw was
106 reported by Jerker Baeck in
107 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
108 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
109 * doc/autoconf.texi (Particular Functions): Move
110 AC_FUNC_SETVBUF_REVERSED from here...
111 (Obsolete Macros): ... to here. Say that it does nothing now.
112 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
113 Turn into (almost) a no-op.
115 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
116 (AC_C_VOLATILE):
117 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
118 These macros are obsolescent and new applications shouldn't need them.
119 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
120 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
121 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
122 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
123 (AC_FUNC_VPRINTF): Likewise.
124 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
125 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
126 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
128 * doc/autoconf.texi (Setting Output Variables): Mention that
129 @VAR1@VAR2 has unspecified behavior. Problem reported by
130 Ralf Wildenhues.
131 * NEWS: Mention this.
133 * Makefile.am: Put only a single '#' into the copyright notice,
134 so that it's also present in the output file. Standardize wording
135 in makefile copyright notices to match GNU coding standards.
136 * bin/Makefile.am: Likewise.
137 * doc/Makefile.am: Likewise.
138 * lib/Makefile.am: Likewise.
139 * lib/freeze.mk: Likewise.
140 * lib/autoconf/Makefile.am: Likewise.
141 * lib/autoscan/Makefile.am: Likewise.
142 * lib/autotest/Makefile.am: Likewise.
143 * lib/m4sugar/Makefile.am: Likewise.
144 * man/Makefile.am: Likewise.
145 * tests/Makefile.am: Likewise.
146 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
147 one-line file.
149 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
151 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
152 in the sed script that mangles the awk script: delete up to the
153 first exclamation mark only.
154 * tests/torture.at (Substitute and define special characters):
155 Test '!' too.
157 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
159 Rewrite config files generation: avoid quadratic growth in
160 the number of substituted variables by using awk instead of sed
161 for the bulk of the substitutions.
162 * NEWS: Mention this.
163 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
164 forbidden in the output (and thus input) file.
165 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
166 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
167 generate just one large awk script for substitutions,
168 eliminating much of the earlier complexity, while adding some
169 new complexity. Only expand the substitution templates at
170 configure time, for smaller configure script size. If
171 _AC_SUBST_FILES are used, test 'awk' for working getline support
172 at config.status time. If absent, interpolate through the
173 shell. The awk script was written with much help
174 from Paolo Bonzini and Paul Eggert.
175 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
176 (_AC_SED_FRAG_NUM): Likewise.
177 (_AC_SUBST_CMDS): Renamed from...
178 (_AC_SED_CMDS): ...this.
179 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
180 * tests/torture.at (Substitute a 2000-byte string): Also
181 substitute a line with 1000 words, and a variable with several
182 long lines.
183 (Substitute and define special characters): Test awk special
184 characters, and put substitution input strings `@foo@' in the
185 output, to test that no recursion happens; test several other
186 combinations from Paolo Bonzini.
188 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
190 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
191 that replaced echo with AS_ECHO where this wasn't necessary.
192 Problem reportd by Ralf Wildenhues.
193 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
194 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
195 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
197 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
199 * lib/freeze.mk (GREP): Removed, no need to initialize this.
201 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
203 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
204 that traditional Awk lacks 3-arg "split". It has it.
205 Mention that FS must be a single character, and a few other
206 99-byte limits of traditional Awk.
207 Mention that if (i in a) doesn't work with traditional Awk.
209 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
211 * tests/autotest.at (BSx641-newline in command):
212 (BS-BS-newline in command, BSx640-newline in command):
213 (Newline-CODE-BS-newline in command):
214 (Single-quote-BS-newline in command):
215 (Single-quote-newline-BS-newline in command):
216 Use printf '%s\n' instead of echo, for portability to hosts
217 where echo interprets backslashes. This will break on hosts
218 that lack printf, but for now let's assume all such hosts
219 are dead (if not, we should get reports of test failures).
221 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
223 'echo' has some portability problems, when given a first argument
224 with a leading '-', or when given any argument containing '\'.
225 Avoid using 'echo' in these cases.
226 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
227 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
228 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
229 * lib/autotest/general.m4 (AT_INIT): Likewise.
230 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
231 argument might be unportable.
232 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
233 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
234 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
235 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
236 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
237 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
238 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
239 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
240 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
241 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
242 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
243 (AC_PROG_MAKE_SET): Likewise.
244 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
245 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
246 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
247 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
248 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
249 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
250 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
251 * bin/autoconf.as: Redo verbose flag implementation, as the old
252 scheme wouldn't work with AS_ECHO.
253 * lib/autotest/general.m4 (AT_INIT): Likewise.
254 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
255 Don't use ECHO_T, since ECHO_N is now reliable.
256 * lib/autotest/general.m4 (AT_INIT): Likewise.
257 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
258 rather than using a here-document to put the script into a file.
259 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
260 use AS_ECHO.
261 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
262 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
263 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
264 bug, but we might as well stop using ECHO_N and ECHO_C internally.
265 * lib/autotest/general.m4 (AT_SETUP): Likewise.
266 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
267 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
268 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
269 operand, as AS_ECHO requires. Avoid double file name expansion.
270 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
271 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
272 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
273 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
274 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
275 Double-quote strings that would otherwise contain M4 comments.
276 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
278 * configure.ac (AC_INIT): Bump to 2.61a.
279 * NEWS: Likewise.
281 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
283 Version 2.61.
285 * configure.ac (AC_INIT): Bump to 2.61.
286 * NEWS: Likewise.
288 * tests/autotest.at (Macro with backslash in a test title):
289 Comment out for now, as this tests neither fails nor passes
290 reliably. Problem reported by Ralf Wildenhues.
292 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
294 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
295 in previous change, which caused test failures.
297 2006-11-16 Stepan Kasal <kasal@ucw.cz>
299 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
300 code for --enable, --disable, --with, and --without to...
301 (_AC_INIT_PARSE_ENABLE): ... a new macro.
302 * doc/autoconf.texi (Package Options):
303 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
305 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>

369 benefit of platforms like Solaris+GCC where it is common to have a
370 non-working g++ installation.
372 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

377 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
378 ./micro-suite.
380 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
382 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
383 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
384 Imported from a similar patch to gnulib by Bruno Haible.
386 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
388 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
389 * doc/autoconf.texi (C Compiler): Document them.
390 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
391 New macros, taken from gnulib.
393 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>
395 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Detect bug in

397 Matthew Woehlke.
399 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
401 * tests/torture.at (Configuring subdirectories): Do not skip
402 Automake 1.10 nor future Automake 11.1 (sic).
404 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
405 and Stepan Kasal <kasal@ucw.cz>
407 Handle special characters in test case titles correctly.
408 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
409 properly.
410 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
411 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
412 argument. Extend to check titles printed by ./micro-suite and
413 ./micro-suite -l and the title in micro-suite.log.
414 (Backquote in a test title,
415 Single-quote in a test title,
416 Double-quote in a test title): Don't expect failure anymore.
417 (Backslash in a test title): Put a non-whitespace character after the
418 backslash so that Bourne shells might actually see it as an escape
419 sequence.
420 (Brackets in a test title,
421 Pound in a test title,
422 Comma in a test title,
423 Quoted Macro in a test title,
424 Macro in a test title,
425 Macro with single-quote in a test title): New tests.
426 (Macro with backquote in a test title,
427 Macro with double-quote in a test title,
428 Macro with backslash in a test title): New tests expected to fail.
429 * tests/torture.at (#define header templates): M4-quote this title in
430 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
431 The visible effect was a stray [] in the testsuite output.
433 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
435 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
436 `trap ... 0' inside a function, for AIX sh.
438 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
440 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
441 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
442 5363) simply issues a warning when dividing by zero at compile
443 time. Problem reported by Elias Pipping.
445 2006-10-26 Eric Blake <ebb9@byu.net>
447 * THANKS: Update.
448 * doc/autoconf.texi (Evaluation Macros): Improve the example to
449 show effect on macros that expand with commas.
450 Reported by Joel E. Denny.
452 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
453 Also work with M4 1.4.8.
455 2006-10-25 Paul Eggert <eggert@cs.ucla.edu>
457 * doc/autoconf.texi (Slashes): Document Tru64 4.0 bug reported by
458 Jim Meyering.
460 2006-10-25 Stepan Kasal <kasal@ucw.cz>
462 * tests/tools.at (autom4te --force): New test, verifies that
463 `--force' always rewrites the output file.

470 2006-10-24 Stepan Kasal <kasal@ucw.cz>
472 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
474 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
476 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
477 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
478 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
479 reported by Nelson H. F. Beebe for Coreutils 6.4.
481 * tests/tools.at (autoconf --trace: user macros): Remove test
482 for tracing multiline macros, since m4 1.4.7a uses a different
483 way to number lines. Problem reported by Ralf Wildenhues.
485 2006-10-24 Stepan Kasal <kasal@ucw.cz>
487 * bin/autom4te.in (handle_m4): Do not redirect stdin to
488 /dev/null since the heuristics for interactive behaviour was
489 fixed in CVS m4.
491 * bin/autom4te.in: With --force, always refresh the output
492 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

509 * NEWS: Remove AC_CACHE_CHECK_INT.
510 * doc/autoconf.texi (Caching Results): Likewise.
511 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
512 AC_CACHE_CHECK_INT, since it's no longer public.
513 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
514 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
516 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
518 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.

544 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
545 looking for special shell characters.
546 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
547 macro defined by AS_VAR_PUSHDEF before passing it as a
548 parameter.
549 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
550 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

559 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
561 (Imported from Automake.)
562 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
563 which incorrectly sets the mode of an existing destination
564 directory. In some cases the unpatched install-sh could do the
565 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
566 system. We hope this is rare in practice, but it's clearly worth
567 fixing. Problem reported by Alex Unleashed in
568 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
569 Also, don't bother to check for -m bugs unless we're using -m;
570 suggested by Stepan Kasal.

574 Import this change from Automake:
576 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

579 Report from Bruno Haible.
581 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

590 Import this change from Gnulib:
592 2006-09-16 Karl Berry <karl@gnu.org>
593 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
594 to avoid sectioning errors.
596 Import these changes from Texinfo:
598 2006-10-04 Karl Berry <karl@gnu.org>
599 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
600 (\quoteexpand): rename to \rquoteexpand.
601 (\codequoteleft): new def, to look for @set codequotebacktick.
602 (\lquoteexpand, \quoteexpand): new defs.
603 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
604 (\code): must use new \...Char values, since now ` is active.
606 2006-08-26 Karl Berry <karl@gnu.org>
607 * build-aux/texinfo.tex (\textdegree): New command.
609 2006-08-12 Karl Berry <karl@gnu.org>

619 added to the template can get mangled.
621 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
623 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
624 include the default headers, and redefine obstack_chunk_alloc
625 and obstack_chunk_free. Fixes false failure with glibc.
627 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
629 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
630 for backward compatibility with Libtool 1.5.22. Problem reported
631 by Ralf Wildenhues.
633 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
635 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
636 AC_PROG_CC.
637 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
639 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
641 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
642 the NonStop platform.
643 * doc/autoconf.texi (Posix Variants): Likewise.
644 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
646 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
647 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
648 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
649 Use a better substitute, by inspecting the output of "ls"
650 rather than just using ":".
651 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
652 rather than AS_EXECUTABLE_P, since we needn't worry about
653 non-regular files here.
655 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
656 due to configuration hassles with this. See Tonya Underwood's report
657 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
658 * doc/autoconf.texi (Special Shell Variables): Likewise.
660 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
661 Stepan Kasal <kasal@ucw.cz>
663 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
664 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
666 2006-10-11 Stepan Kasal <kasal@ucw.cz>
668 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
669 initialization which is not inherited through the environment
670 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
671 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
673 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
675 * doc/autoconf.texi (Limitations of Usual Tools): Describe
676 problems with mkdir -p -m.
678 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
680 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
681 comment about ac_cpp_err; it was incorrect, and anyway
682 ac_cpp_err is being removed below.
683 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
684 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
685 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
686 nobody uses it.
687 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
688 with werror_flag and conftest.err and so forth. This is more
689 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
690 and anyway the user shouldn't normally want to see this gorp logged.
691 Problem reported by Ralf Wildenhues.
692 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
693 empty, not 'no', since the rest of the code uses 'test -z'.
695 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
697 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
698 Use a single call to AC_DO_TOKENS rather than multiple, for
699 efficiency.
700 (_AC_LINK_IFELSE): Test that resulting file is executable.
701 Problem reported by mwoehlke in
702 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
704 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
705 than creating a file to use with test -x; this is much faster.
707 2006-10-02 Bruno Haible <bruno@clisp.org>
709 * lib/autom4te.in (Automake-preselections): Add
710 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
712 2006-09-27 Stepan Kasal <kasal@ucw.cz>
714 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
715 standard error, `experr' should be used, not `expout'.
717 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
719 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
720 fseeko testing program twice; just use the earlier result.
721 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
722 Set cache var to 'unknown' (not 'no') if leaving the macro unset
723 still doesn't let the program compile.
724 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
725 failed.
727 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
728 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
729 include it, without including anything else.
730 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
731 expressions.
732 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
734 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
736 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
737 `error.h', and include it, for a `error_at_line' prototype.
738 Use a nonempty format string in the link test.
739 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
740 for a declaration of wait3.
742 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
744 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
745 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
746 can apply to constants too, and that it checks for macro defns.
747 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
748 and simply cast the identifier to void. This handles structure
749 values. Problem reported by Ralf Wildenhues.
750 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
752 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
754 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
755 structure, and function symbols.

772 warnings (uninitialized value).
773 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
774 present.
775 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add
776 parentheses.

805 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
806 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
807 --error-output, to avoid warnings with M4 2.0.
809 2006-09-19 Stepan Kasal <kasal@ucw.cz>
811 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be
812 consistent with _AH_CHECK_FUNCS and _AH_CHECK_HEADERS.
813 * lib/autoconf/headers.m4 (AH_CHECK_HEADERS_DIRENT): Likewise.
815 2006-09-15 Stepan Kasal <kasal@ucw.cz>

820 2006-09-14 Stepan Kasal <kasal@ucw.cz>
822 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
823 mistaken comment: the path has to be relative; do not use
824 the path at runtime.
826 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
828 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

832 for both changes.
833 * doc/autoconf.texi (Setting Output Variables): Fix example to
834 not show `--silent' being passed to a `configure' re-run.
836 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
838 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
839 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
840 for the existence of the directory at configure-time. That's
841 too late, anyway. Problem reported by Stefan Seefeld.
843 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
844 7.1.4 /usr/bin/posix/sh described by Tim Rice in
845 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
847 2006-09-11 Stepan Kasal <kasal@ucw.cz>
849 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
850 works with GNU M4 1.4.3 again; make the normalized form
851 match the current m4 message; fix the description.
852 * test/tools.at (autom4te cache): Adapt to the change.
854 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
856 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
857 to catch glibc bug 2821
858 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
860 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
861 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
862 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
863 assume C89.
865 2006-09-08 Stepan Kasal <kasal@ucw.cz>
867 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the
868 preselections ...

880 top_srcdir are not necessarily relative. Problem reported
881 by Dries Kimpe.
883 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
885 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
886 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
887 accept files with extension `.f'. For consistency, also prefer
888 xlf over f77.
889 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
890 from last patch.

907 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
909 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
910 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
911 except the first two arguments are reversed.
912 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
913 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
914 caches nor outputs a diagnostic. Suggested by Bruno Haible.
915 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
916 equivalent to the old AC_COMPUTE_INT.
917 (AC_COMPUTE_INT): No longer caches or reports. New signature.
918 All uses changed to AC_CACHE_CHECK_INT.
919 * tests/base.at (AC_CACHE_CHECK_INT): New test.

924 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
925 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
926 programs should use their Gnulib counterparts.
927 * doc/autoconf.texi (Particular Functions): Likewise.
928 (Macro Names, testsuite Invocation): Replace uses of these
929 obsolete macros with uses of non-obsolete macros.
931 2006-08-29 Eric Blake <ebb9@byu.net>

943 * NEWS: Version 2.60a.
945 2006-08-25 Stepan Kasal <kasal@ucw.cz>
947 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Remove the IPA/IPO
948 file created by the PGI compiler.
950 2006-08-25 Noah Misch <noah@cs.caltech.edu>
952 * lib/Autom4te/General.pm (END): Use `File::Path::rmtree' to
953 simplify the code.
955 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
957 Fix Lex library problem reported to us by Julio Garvia.
958 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
959 for the default, which the user can override.
960 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
961 deal with LEXLIB.
962 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
963 didn't work if some values were cached but not others. Test for
964 broken lex libraries like native ia64-hp-hpux11.22; see
965 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
966 work around the problem by preferring an empty LEXLIB to -lfl or
967 -ll. Let the user set LEXLIB='' to indicate no library needed.
969 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
970 * README: Likewise.

1096 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
1097 * doc/autoconf.texi (Header Templates, Default Includes):

1112 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1113 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1114 this.
1116 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
1118 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1119 problems with arg script text that doesn't end in newline, and

1122 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
1124 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
1125 check for libXt by a check for libX11.
1127 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1134 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1135 --help' should mention that `--version' outputs configuration
1136 settings. Report by Bruno Haible.
1138 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1140 Fix test suite failures reported by Pierre in
1141 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.

1143 the compiler created a file "b.out" when it didn't create anything
1144 at all.

1146 Discard stderr too, when invoking the test script.

1156 less skeptical about "volatile", after discussion with
1157 Bruno Haible on bug-gnulib.
1158 (Limitations of Usual Tools): Warn about sed stripping
1159 leading white space from text. From Bruno Haible.
1161 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1163 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1164 compiler complains about it, even if things works after the
1165 complaint. Problem reported by Peter O'Gorman.
1167 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1168 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1169 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1171 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1173 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

1178 * README: Likewise.
1179 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
1180 * tests/tools.at (autom4te cache): Update wording of diagnostic
1181 to match M4 1.4.5.
1183 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1185 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1186 under AC_C_VOLATILE.
1187 (Volatile Objects): Be a little less skeptical about what
1188 "volatile" means. Derived from thoughts by Ben Pfaff in
1189 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1191 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1193 * doc/autoconf.texi: Fix some typos.
1195 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1197 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1198 more globally, since the 2006-06-30 patch didn't suffice. Problem
1199 reported by Keith Marshall. Also, don't bother with builddir2,
1200 since it shouldn't be needed any more.
1202 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1204 * doc/autoconf.texi (Generic compiler characteristics):
1205 Document AC_COMPUTE_INT. Fix wrong statements on Default
1206 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.

1211 AC_COMPUTE_INT.
1213 * NEWS: Document change.
1215 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
1217 * doc/autoconf.texi (Volatile Objects): New section.
1219 * NEWS: Document previous change.
1221 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1223 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1224 Require that long long int be at least 64 bits wide. C99 requires
1225 this and enough programs depend on it so we should check for it.
1226 Bruno Haible reports in
1227 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1228 that long long int is 32 bits wide with some nonstandard compilers.
1229 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1231 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1233 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1234 to a nonexistent file, so that we don't have to worry about
1235 a local site configuration that doesn't use /usr/local.
1236 Problem reported by Keith Marshall in
1237 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1239 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1241 * doc/autoconf.texi: Be more consistent about using @acronym with
1242 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1243 quite right (it talked about "OSF/Tru64", even though the
1244 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1245 and it even mentioned "OSF 4"!) and at this point there's little
1246 reason to talk about OSF any more, since it died in 1994.
1247 (Specific Compiler Characteristics): Simplify example of
1248 negative-size array.
1249 (File Descriptors): Reorder to make the text flow better.
1250 Remove joke about "appreciate the various levels"; I didn't get it.
1251 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1252 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1253 (File Descriptors, Limitations of Usual Tools):
1254 Tone down the advice against renaming or removing open files.
1255 (Limitations of Usual Tools): Add a new section, on 'rm'.
1257 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1259 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1260 -lXt in LIBS, idea from Karsten Hopp; this was due since
1261 this change:
1263 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1264 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1265 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1266 (which belong to Xt, not X itself). See Debian bug 327655.
1268 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1270 * configure.ac (AC_INIT): Bump to 2.60a.
1271 * NEWS: Update.

1279 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1281 * config/texinfo.tex: Sync from upstream.
1283 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1284 quadrigraph correctly in traces.
1286 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1287 Fix typos.
1289 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1290 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1291 not defined.
1292 * doc/autoconf.texi (Changed Directory Variables): New node,
1293 to document the whole `datarootdir' business a bit better.
1294 * NEWS: Update.
1295 * tests/torture.at (datarootdir workaround): Extend test.
1296 Prompted by report by Alexandre Julliard.
1298 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1300 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility

1302 fix reported by Larry Jones.
1304 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1306 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1307 about literal '${datarootdir}' if a definition is found in the
1308 output file.
1310 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1312 * NEWS: Use "M4" rather than "m4" when appropriate.
1313 Problem reported by Eric Blake.
1314 * doc/autoconf.texi: Likewise.
1315 Use @acronym around BSD, GCC, and GNU when appropriate.
1316 (Why GNU M4): Renamed from "Why GNU m4".
1317 (Redefined M4 Macros): Mention that Posix
1318 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1319 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1320 to int.
1322 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1324 * bin/autom4te.in (handle_output): Do not forbid the empty
1325 pattern.
1326 * tests/tools.at (autoconf: the empty token): New test.
1328 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1330 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1331 calls, so that we do not care whether they are LIFO or FIFO;
1332 in the m4_wrap, do not check which diversion is the topmost
1333 one, just check that the stack is balanced at the end.
1334 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1335 base diversion forever--pop the previous diversion before
1336 opening the new one; consequently, remove the m4_wrap call.
1337 * lib/autotest/general.m4 (AT_INIT): Likewise.
1338 * tests/m4sugar.at: Do not use
1339 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1341 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1342 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1344 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1345 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1346 Rework example of m4wrap token-pasting trouble so that it doesn't
1347 care whether it's LIFO or FIFO.
1348 Fix some "contrary to"s that are awkward in English.
1350 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1352 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1353 to `yes' instead of `int$1_t' if the type is found, for more
1354 consistent configure output (where $1 is the number of bits).
1355 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1356 Suggested by Bruno Haible.
1358 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1359 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1360 with system headers. Report by Bruno Haible.
1362 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1364 * config/config.guess, config/config.sub: Sync from upstream.
1366 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1367 in order to avoid picking up an older installed frozen m4sh.m4f.
1368 Besides an outdated shell startup, this could have been created
1369 by an earlier M4 version with incompatible frozen file format.
1371 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1373 * README: Recommend m4 1.4.4 instead of 1.4.3..
1374 * doc/autoconf.texi: Likewise.
1375 (Special Chars in Names): Say that $(.FOO) is portable, as
1376 suggested by Stepan Kasal.
1377 (Installation Directory Variables, Build Directories):
1378 (Automatic Remaking, Subdirectories, Fortran Compiler):
1379 (Making testsuite Scripts, Defining Directories):
1380 Quote variable usages better.
1381 (Making testsuite Scripts): Add clean-local rule to makefile
1382 snippet, by Eric Blake.
1383 (Installation Directory Variables): Fix table item font.
1384 Reword slightly to clarify. Generalize advice about
1385 not using special characters to include all file-related
1386 vars, not just VPATH.
1387 (Special Chars in Variables): Warn about special characters in
1388 $(srcdir) too.
1389 (Assignments): Clarify default-value example as suggested by
1390 Ralf Wildenhues in
1391 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1392 (Special Shell Variables): Note leading ./ or ../, as suggested
1393 by Eric Blake.
1394 (Limitations of Builtins): Under cd, warn about CDPATH.
1395 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1396 Ralf Wildenhues.
1398 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1400 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1401 `@var', for texi2html.
1402 (Systemology): Some more word wrapping, for DVI output.
1403 (autom4te Invocation): The short option for `--melt' is `-M',
1404 not `-m'.
1406 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1408 * doc/autoconf.texi: More formatting and English tweaks,
1409 many suggested by Ralf Wildenhues.
1410 Reword to avoid "@code{...}'s" and the like, since it's ugly
1411 with Emacs info mode. discontents -> woes.
1412 Put a few "will"s back. time stamp -> timestamp.
1413 side-effect -> side effect.
1415 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1417 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1418 Warn about $@ not persisting. Problem reported by Julien Danjou in
1419 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1420 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1421 Mention other special chars, too.
1423 2006-06-14 Eric Blake <ebb9@byu.net>
1425 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1427 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1429 * doc/autoconf.texi: Some systematic minor improvements, as
1430 follows. Use "makefile" when talking about makefiles
1431 generally (which might be named "makefile" or "Makefile" or even
1432 "foo.mk"), "Makefile" when talking about a specific makefile
1433 called "Makefile". This unclutters the text from weird quotes
1434 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1435 values" rather than "@var{foo}s" and similar constructs containing
1436 "}s". Use "Make rules" rather than "Makefile rules". Minor
1437 English-language improvements. Change the prefix "sub-" to "sub"
1438 and "re-" to "re".
1439 Put blank lines around examples more consistently.
1440 Avoid "rather" and "very" as intensifiers.
1441 Avoid "will" as an auxiliary.
1442 (Limitations of Make): Split this node into....
1443 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1444 (Leading _ in Macro Names, Backslash-Newline-Newline):
1445 (Backslash-Newline Comments, Long Lines in Makefiles):
1446 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1447 (obj/ and Make, make -k Status, VPATH and Make):
1448 (VPATH and Double-colon, $< in Explicit Rules):
1449 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1450 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1451 New nodes, resulting from splitup of Limitations of Make.
1452 All cross-references changed. Raise the top node from
1453 a section to a chapter, and all subnodes accordingly.
1454 Redo the introductory wording to match the new organization.
1455 (Installation Directory Variables): Use an example that is
1456 closer to what Autoconf actually does. Mention that VPATH's
1457 value should not contain metacharacters or white space.
1458 (Fortran Compiler): Fix a VPATH bug in an example.
1459 (Leading _ in Macro Names): Mention that this problem is no longer
1460 of practical concern.
1461 (VPATH and Make): Reword the advice to make it clearer
1462 that Autoconf and Automake support VPATH in non-GNU make, but
1463 many packages have bugs in this area.
1464 ($< in Explicit Rules): Refer to Build Directories rather
1465 than using a (non-VPATH-safe) example.
1466 (Automatic Rule Rewriting): Mention the sort of disaster that
1467 can ensue with Solaris-style rule rewriting with VPATH.
1469 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1471 * doc/install.texi (Compilers and Options): Weaken the
1472 suggestion to use GNU make for VPATH builds.
1474 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1475 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1477 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1478 in regular expression.
1480 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1482 * doc/autoconf.texi (Installation Directory Variables):
1483 Drop extra @samp from `@table @samp' item.
1484 (Limitations of Usual Tools): Comment fix.
1485 Do not nest @samp just to point to other table items.
1486 (Writing testsuite.at) <AT_CHECK>: The second argument to
1487 `@dvar' is already @samp'ed.
1488 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1489 do not use @var in the second argument.
1491 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1493 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1494 $as_shell.exe too. Problem reported by Andreas Buening in
1495 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1497 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1499 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1500 `unused variable' compiler warning, for `-Wall -Werror'.
1501 Reported by Jaap Haitsma in
1502 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1504 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1506 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1507 case the compiler dumps core. Problem reported for
1508 OpenServer 5.0.7 by Tim Rice in
1509 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1510 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1511 Likewise.
1513 2006-06-06 Tim Rice <tim@multitalents.net>.
1515 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1516 "ERROR" only shows up in "make check" output if there is an
1517 error.
1519 2006-06-06 Eric Blake <ebb9@byu.net>
1521 * tests/tools.at (automatically allowed tokens): Fix typo.
1523 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1525 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1527 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1528 typically overflows on x86 CPUs, even though the C standard
1529 requires otherwise.
1531 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1533 * configure.ac (AC_INIT): Bump to 2.59e.
1534 * NEWS: Update.
1536 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1538 Version 2.59d.
1540 * config/texinfo.tex: Sync from upstream.
1542 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1543 seen, invoke libtoolize with `--ltdl' argument.
1544 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1545 * NEWS: Update.
1546 Suggested by Eric Blake.
1548 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1550 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1551 reported by Ralf Wildenhues.
1552 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
1554 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1556 * THANKS: Update.
1558 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1560 * doc/autoconf.texi: Modernize some of the references to Solaris.
1562 2006-06-05 Stepan Kasal <kasal@ucw.cz>
1564 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
1565 message issued by AC_REQUIRE.
1566 * tests/m4sugar.at: Check m4_require's error message.
1567 * tests/base.at: Check AC_REQUIRE's error message.
1568 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1569 to...
1570 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1571 AT_CHECK_M4.
1572 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1573 `expout' as the last parameter.
1574 * tests/tools.at: Adapt to the above change.
1576 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1578 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1579 information about race-free implementations of mkdir.
1581 2006-06-04 Eric Blake <ebb9@byu.net>

1584 * bin/autoconf.as (Usage): Likewise.
1585 * bin/autom4te.in (help): Likewise.
1586 * doc/autoconf.texi (autom4te Invocation): Likewise.
1588 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1590 * NEWS: GNU make now recommended for VPATH builds.
1591 Mention that some macros are now documented to be obsolescent.
1592 * doc/autoconf.texi:
1593 Prefer "current" to "modern" to describe
1594 currently-used (albeit perhaps old-fashioned) hosts.
1595 Mention which ancient features no longer need to be worried about.
1596 setgid -> set-group-ID
1597 setuid -> set-user-ID (these are the Posix terms)
1598 Fix some misuses of "only".
1599 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1600 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1601 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1602 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1603 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1604 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):

1606 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1607 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1608 Mention that these macros are obsolescent.
1609 (Installation Directory Variables): shall -> should
1610 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1611 Mention that it's now safe to use 3 and 4.
1612 (Limitations of Usual Tools): cp -r is now specified by Posix.
1613 Omit longwinded and obsolescent discussion of cp -f.
1614 Modernize discussion of expr, ls.
1615 (Limitations of Make): Modernize discussion of VPATH builds.
1616 Mention $? as a workaround in some cases.
1617 * doc/install.texi (Basic Installation):
1618 Mention "./configure; make; make install" first. Be more
1619 specific about why this file is generic. Remove unnecessary
1620 parens. Remove misleading "only". Remove obsolete advice
1621 about csh. Don't say "configure" takes awhile; say it
1622 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1623 and CC=c99 rather than CC=c89, as these are blessed by current
1624 Posix. Recommend GNU make if doing a VPATH build.
1626 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1628 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1629 examples involving shell prompts.
1631 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1632 and Paul Eggert <eggert@cs.ucla.edu>
1634 * doc/autoconf.texi (Here-Documents): Add details about the
1635 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1636 use "here-documents" instead of "here documents".
1638 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1640 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1642 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1644 * doc/autoconf.texi (File System Conventions): Warn about ":"
1645 anywhere in directory names.
1647 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1649 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1650 about quoting the case statement, just in case.
1651 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1652 was fixed in ksh93g; reported by Ralf Wildenhues.
1654 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1656 * doc/autoconf.texi (System Services): Do not document
1657 overriding EXEEXT via ac_cv_exeext=ext.
1658 (Particular Programs) <AC_PROG_MKDIR_P>:
1659 Document that ${MKDIR_P} understands --.
1660 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1661 comment.
1663 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1665 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1666 argument with leading hyphen. Problem reported by Paul Eggert.
1668 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1670 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1671 about quoting ac_try: quote all of it, if any of it seems suspicious.
1672 This means we don't have to worry about ${ or sed any more.
1673 Also, double-quote the case statement, to work around misuses via
1674 underquoting as reported by Ralf Wildenhues in
1675 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1676 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1677 undocumented and dangerous macro.
1678 Problem reported by Ralf Wildenhues in
1679 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1681 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1683 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1684 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1685 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1687 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1689 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1690 since evidently some packages rely on the old, broken behavior.
1691 Problem reported by Ralf Wildenhues in
1692 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1693 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1694 pre-2006-05-26 definitions, but leave in the comments that
1695 these macros are dangerous and should not be used.
1696 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1697 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1698 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1699 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1700 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1702 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1704 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1705 the use of 'tr', since this is our only use of 'tr'.
1707 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1708 and Paul Eggert <eggert@cs.ucla.edu>
1710 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1711 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1713 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1715 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1716 the output file in the `${datarootdir}' test.
1718 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1719 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1721 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1722 mention of `datarootdir' in the input file(s), but literal
1723 `${datarootdir}' in the output file, and we haven't warned yet,
1724 then warn as well: the user may have (erroneously) used
1725 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1726 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1727 * tests/torture.at (datarootdir workaround): Extend this test.
1728 * NEWS: Update.
1730 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1731 and Paul Eggert <eggert@cs.ucla.edu>
1733 * doc/autoconf.texi (autoheader Invocation): The first argument to
1734 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1735 alternatives and clear up the language a bit.
1737 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1739 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1740 ac_config_guess, ac_config_sub, ac_configure.
1741 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1742 Fix typo that prevented an unnecessary space from being removed.
1743 Problems reported by Ralf Wildenhues in:
1744 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1746 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1748 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1749 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
1750 Don't use the term "thread-safe" to talk about mkdir race
1751 conditions, since the problem is more a process than a thread
1752 issue. Problem reported by Stepan Kasal in:
1753 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
1754 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
1755 the test for 'install' more closely. Look at MKDIR_P first.
1756 Look in the PATH, and at /opt/sfw/bin.
1757 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1758 Don't bother to try mkdir -p, since we already check mkdir --version;
1759 just look at the version number. (There's no easy way to check
1760 for race-free implementations.)
1761 * tests/tools.at (autoconf: subdirectories): Adjust to above
1762 changes, since MKDIR_P now might end in "/mkdir -p".
1764 * doc/autoconf.texi (autoheader Invocation): Mention that the
1765 first arg of AC_DEFINE_UNQUOTED must be a literal.
1766 Problem reported by Ben Pfaff in
1767 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1769 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1770 * doc/autoconf.texi (Special Chars in Variables): New section.
1771 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1772 (Installation Directory Variables): Quote $(datadir) better.
1773 (Limitations of Builtins): Describe some of eval's trickiness.
1775 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1776 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1777 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1778 in front of every arg, not just trailing args. Quote apostrophes.
1779 (_AC_EVAL_ECHO): New macro.
1780 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1781 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1782 removed.
1783 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1784 exposed by quoting of eval argument. Put the command on line line
1785 so it logs better.
1786 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1787 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1788 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1789 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1790 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1791 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1792 Use eval more safely.
1793 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1794 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1795 to be replaced.
1796 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1797 lines, exposed by quoting of eval argument.
1799 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1800 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1802 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1803 initialization of `ac_cv_exeext', do not override it if it was
1804 already set, unless it was set to `no', for compatibility with
1805 Autoconf-2.13, and comment this.
1806 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1807 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1808 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1809 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1810 Document that this test may be overridden by setting
1811 `ac_cv_exeext'.
1813 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1818 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1819 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1820 2006-04-01.
1822 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1823 Clean up _AC_COMPILER_EXEEXT* macros.
1824 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1825 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1826 ac_file to the name of the default output file and call
1827 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1828 initial `rm' of the candidate files...
1829 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1830 the same list in subsequent `rm' calls, and for the temporary
1831 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1832 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1833 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1834 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1835 no longer needed) by libtool. Make it a cache check.
1836 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1837 copied here by mistake.
1838 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1839 _AC_COMPILER_EXEEXT.
1840 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1841 _AC_COMPILER_OBJEXT directly.
1842 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1844 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1846 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1847 Fix description of how the buggy `sed' works.
1849 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1851 Sync from Automake:
1853 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1854 ENOLCK. Only mention `make -j' when applicable. Only raise
1855 fatal errors when `make -j' is involved. Improve error message.
1857 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1859 * doc/autoconf.texi (Here-Documents): We now know more about
1860 the variable expansion in here documents bug.
1861 Thanks to Tim Rice and Stepan Kasal.
1863 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1864 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1866 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1868 * tests/autotest.at (Multiline command from M4 expansion):
1869 No failure to be expected if the shell quotes newlines in
1870 commands in the `set -x' output. Report by Tim Rice.
1871 * THANKS: Update.
1873 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1875 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1876 expansion in the here-documents used by config.status, as that
1877 runs afoul of the Korn shell version M-12/28/93d bug described in
1878 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1879 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1880 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1882 2006-05-23 Jim Meyering <jim@meyering.net>
1884 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1885 Fix typo introduced with 2006-04-02 change. It reversed the sense
1886 of the test.
1888 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1890 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1891 ac_dB slightly, to save bytes in the script.
1892 Max out at 50 lines, rather than 96; this is more likely
1893 (though not guaranteed) to avoid obscure 'sed' failures.
1895 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1897 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
1898 `tr -d -' as bad option argument. Work around this by deleting
1899 an unrelated character.
1900 Report by Tim Rice <tim@multitalents.net>.
1902 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
1903 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1904 Stepan Kasal <kasal@ucw.cz>
1906 * doc/autoconf.texi (Particular Programs): Do not promise that
1907 we always prefer the GNU version of the program, and that we
1908 search according to PATH; both rules can have exceptions.
1909 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
1910 AC_PROG_SED. Move descriptions of limitations
1911 to the Limitations of Usual Tools section.
1912 (Limitations of Usual Tools) <sed>: Mention script length
1913 limitations with Solaris /usr/ucb/sed.
1914 <grep>: Fix wording for empty alternative. Mention that -c and
1915 -l should not be combined, and that -E and -F should not be
1916 combined.
1918 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1919 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1921 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
1922 limits in Solaris 8 /usr/ucb/sed by testing a long script.
1924 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1926 * doc/autoconf.texi (Defining Symbols): Literal parameter of
1927 AC_DEFINE is now passed to m4_pattern_allow.
1928 * NEWS: Mention that; likewise for AC_SUBST.
1929 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
1930 the parameter to m4_pattern_allow.
1931 * tests/tools.at: Add a check for that.
1933 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1935 * lib/autoconf/status.m4: Fix typos.
1937 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1939 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1940 only the files that this macro generates.
1942 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1944 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1945 the HP-UX sed limitation of 99 commands, labels do not count.
1946 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1947 in the comment.
1948 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1950 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1952 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1953 Import the following fix from coreutils:
1955 2006-01-13 Jim Meyering <jim@meyering.net>
1957 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1958 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1959 not double-quote uses of that variable, to accommodate the rare
1960 case in which getmntent is available in none of the libraries
1961 checked. This happens at least on FreeBSD 5.0.
1963 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1965 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
1966 ac_config_guess, ac_config_sub, and ac_configure, since evidently
1967 some other programs unwisely rely on these undocumented vars.
1968 But put in warning comments about them.
1969 Problem reported by Ralf Wildenhues in
1970 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
1971 * NEWS: Document that these variables are intended to go away.
1973 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1975 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
1976 and set the language to C++ (analogous to the equivalent Fortran
1977 tests).
1979 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
1980 * doc/autoconf.texi (C++ Compiler): Document it.
1981 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
1982 * NEWS: Update.
1984 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1986 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
1987 that caused config.status to generate 100-command sed scripts; the
1988 portable limit is 99.
1990 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1992 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
1993 variable `ac_d' instead of `d' to avoid infringing namespace.
1994 Report by Ralf Menzel.
1996 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
1998 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
1999 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2000 * tests/tools.at (autoconf: subdirectories): New test, taken from
2001 the corresponding problem report by Ralf Wildenhues in:
2002 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2004 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2005 Quote some uses of shell variables if they might suffer unexpected
2006 globbing. This doesn't fix all instances of quoting problems that
2007 I found, just the easy ones that look safe.
2008 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2009 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2010 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2011 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2012 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2013 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2014 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2015 Likewise.
2016 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2017 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2019 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2021 * bin/autoreconf.in ($help): Reword according to the manual.
2022 Suggested by Olly Betts.
2024 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2025 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2027 * bin/autoreconf.in: Pass the directory argument to
2028 `require_configure_ac'. Fix comment.
2029 * tests/torture.at (Configuring subdirectories): Expose this.
2030 Reported by Olly Betts.
2032 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2034 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2035 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2036 Automake as follows:
2038 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2039 `$configure_in' instead of `configure.in', to preserve
2040 directory component.
2042 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2044 * config/config.guess, config/config.sub, config/texinfo.tex,
2045 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2047 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2049 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2050 test for C99 conformance; (bool) 0.5 is an integer constant
2051 expression, but (bool) -0.5 is not. Problem reported by Fedor
2052 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2054 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2056 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2057 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2058 Warn about obsolete install-sh files. Remove stray sentence
2059 fragment and fix cross reference.
2060 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2061 install -d; this undoes the 2006-05-10 change.
2062 (MKDIR_P): Mark with AN_MAKEVAR.
2063 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2064 that we don't require $INSTALL to be thread-safe. Move comments
2065 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2066 of AC_PROG_INSTALL. Output a message saying that we're checking
2067 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2068 MKDIR_P instead of AC_SUBST.
2069 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2070 Special magic for MKDIR_P, too.
2071 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2072 a dnl.
2073 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2075 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2077 Sync from Automake, as follows:
2079 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2080 * config/install-sh: Initialize IFS, so field splitting isn't
2081 turned off later.
2082 * config/mkinstalldirs: Likewise.
2083 * config/missing: Remove superfluous quotes. Replace all uses of
2084 `[' by `test', for consistency, and for..
2085 * config/missing (sed_minuso, sed_output): New variables.
2086 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2087 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2088 Fixes `missing' to detect `--output' for help2man. Fixes
2089 PR automake/483. Report by Dennis J. Linse.
2090 (autom4te): Document in `missing --help'.
2092 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2094 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2095 * config/install-sh: Don't use 'path' to talk about file names,
2096 as per GNU coding standards. Close a race condition reported by Ralf
2097 Wildenhues and Stepan Kasal. There is still a race condition
2098 on hosts that predate Posix 1003.1-1992, but we can't help this.
2099 Don't mishandle weird characters like space on pre-Posix hosts.
2100 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2101 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2102 AC_PROG_MKDIR_P from AS_MKDIR_P.
2103 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2104 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2105 earlier editions are not (including Automake 1.8.3).
2106 Do not suggest mkinstalldirs for thread-safety.
2107 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2108 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2109 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2110 presence of special characters and race conditions.
2111 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2112 in Autoconf's name space.
2114 2006-05-10 Bruno Haible <bruno@clisp.org>
2115 and Paul Eggert <eggert@cs.ucla.edu>
2117 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2118 from Automake with minor changes.
2119 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2121 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2123 * config/install-sh: Update to Automake CVS version, as follows:
2124 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2125 * lib/install-sh: Simplify the expr implementation of dirname.
2126 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2127 * lib/install-sh: Handle --, and diagnose unknown options.
2129 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2131 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2132 `./autom4te' to create `./testsuite', since the `all' target
2133 will ensure its presence, but `installcheck' should not create
2134 the uninstalled wrappers.
2136 * tests/torture.at (Unusual Automake input files): Skip if we
2137 detect automake < 1.8.
2139 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2141 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2142 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2143 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2144 * NEWS: Update.
2146 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2148 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2149 munge (multiple) white space and other oddities.
2150 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2151 single quotes in variable assignment.
2152 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2153 and similar failures by adding multiple spaces, tabs, and other
2154 special characters.
2155 Report and different test suggested by Francesco Romani
2156 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2158 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2159 single quotes, we only need to search for single quotes; this
2160 both simplifies the search pattern, and makes us less
2161 susceptible to `echo' variations for arguments not containing
2162 single quotes.
2163 (_AC_ARG_VAR_VALIDATE): Likewise.
2165 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2167 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2168 `$*' and IFS concatenation issue with traditional shells and
2169 bash-2.04. Report by Seanster@Seanster.com.
2171 2006-05-03 Bruno Haible <bruno@clisp.org>
2173 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2174 precisely which Mac OS X versions have the od problem.
2176 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2178 * doc/autoconf.texi: Use @option systematically.
2180 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2181 and Bruno Haible <bruno@clisp.org>
2183 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2184 about 'od'.
2185 (Integer Overflow): Mention the special case of integer division
2186 overflow.
2188 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2190 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2191 traditional shells like the Solaris one that do not use the
2192 first IFS character for assembling `$*'.
2193 Prompted by a related report from autoconf_bug@nro.ca.
2195 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2196 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2198 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2199 Mention more problems with the -e option.
2201 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2203 * NEWS: Typo.
2204 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2206 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2207 in URLs to improve DVI formatted output (requires texinfo 4.6).
2208 (System Services, Systemology, Shellology): Likewise.
2209 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2210 output.
2212 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2213 continuous text.
2214 (Runtime): Fix macro argument names to match description:
2215 `action-if-found' -> `action-if-true' and similarly.
2216 (Obsolete Macros): Likewise.
2217 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2218 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2219 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2221 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2223 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2225 * ChangeLog: Typo.
2226 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2227 DVI output.
2229 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2234 * tests/local.at: Likewise.
2236 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2238 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2239 (Integer Overflow, Null Pointers, Buffer Overruns):
2240 (Floating Point Portability, Exiting Portably): New sections.
2241 (Writing Test Programs): Fix some langauge. Recommend exiting
2242 with status 1, not merely nonzero. Clarify exit declaration.
2243 (Run Time): Move C exit status stuff to new Exiting Portably section.
2244 (Systemology): Mention Posix and levenez. Update v7 reference.
2245 (Portable Shell): Mention the Posix shell.
2247 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2249 * bin/autoconf.as (me): Replace by as_me.
2251 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2253 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2254 since as_me isn't set yet.
2256 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2258 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2259 a few minor bugs in this area.
2261 * doc/autoconf.texi (Programming in M4sh): Comment out the
2262 documentation of AS_BASENAME, for now.
2263 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2264 (Limitations of Builtins) <basename>: Do not refer to
2265 AS_BASENAME.
2266 * bin/autoconf.as (me): Don't use AS_BASENAME.
2267 (dir): Remove the unused variable.
2268 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2269 AS_DETECT_REQUIRED. All uses changed.
2270 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
2271 All uses changed.
2272 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
2273 (AS_BASENAME): Use "basename --" to protect against leading "-".
2274 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2275 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2276 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2277 (_AS_DIRNAME_PREPARE): Likewise.
2278 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2279 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2280 (AS_DIRNAME): Use "dirname --".
2282 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2284 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2285 of "run time" and "run-time" changed to "runtime", for consistency.
2286 * lib/autoconf/fortran.m4: Likewise (in comment).
2287 * lib/autoconf/functions.m4: Likewise.
2288 * lib/autoconf/general.m4: Likewise.
2289 * lib/autoconf/headers.m4: Likewise.
2291 * doc/autoconf.texi (Run Time): Document the exit status situation
2292 with more accuracy and detail.
2294 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2296 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2297 Archive is not officially `GNU' any more. Update URL.
2298 (Defining Directories): Likewise
2299 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2301 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2303 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2304 newline from the `trap' code to finish `config.log'; the NetBSD
2305 /bin/sh resets the exit status after an empty command, as
2306 documented in doc/autoconf.texi.
2307 Reported by Dalibor Topic <robilad@kaffe.org>.
2309 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2311 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2312 Suggested by Bruno Haible.
2314 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2316 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2317 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2318 Instead, just list the shells that we know work.
2319 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2320 changed. Be more cautious about the _cv_ variable.
2321 * tests/tools.at (Syntax of the shell scripts): Check the
2322 _cv_ variable once, at first, to avoid an internal autoconf error
2323 when sh -n does not work.
2325 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2327 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2329 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2331 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2332 use ">&-" since we're only 99.999% sure that this is portable,
2333 and since the MinGW bug is fixed in a different way.
2334 * lib/autotest/general.m4 (AT_INIT): Likewise.
2336 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2338 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2339 before opening config.log, to avoid hitting a bug on MinGW.
2341 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2343 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2344 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2345 This works around a MinGW bug reported by Eric Paire.
2346 Make sure that all writes to the log file append to it,
2347 rather than possibly losing data.
2348 * lib/autotest/general.m4 (AT_INIT): Likewise.
2350 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2352 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2353 description.
2355 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2357 * NEWS: Update.
2359 * configure.ac (AC_INIT): Bump to 2.59d.
2361 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2363 Version 2.59c.
2365 * Makefile.maint (news-date-check): Do not require a leading `*'
2366 before the release date in NEWS.
2368 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2369 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2371 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2372 the instantiated file do not contain the string 'datarootdir'
2373 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2374 @mandir@, replace the reference '${datarootdir}' by the value.
2375 * tests/torture.at (datarootdir workaround): New test.
2376 * NEWS: Advertise this temporary fixup.
2377 Based on a patch by Bruno Haible, reported and analyzed by
2378 Paul Eggert and Noah Misch.
2380 2006-04-12 Eric Blake <ebb9@byu.net>
2382 * tests/autotest.at (Debugging a failed test): Fix comment.
2384 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2386 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2387 all the changes since 2006-04-07.
2389 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2391 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2392 succeeded, but `ln -s file dir' failed, take care to remove the
2393 leftover target before the next test, to prevent its spurious
2394 failure; also make sure `ln file dir' works before selecting it.
2395 Thanks to Keith Marshall for pointing this out.
2396 * THANKS: Update.
2398 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2399 assignments in `at_debug_args', so that we put them correctly
2400 in the `run' script.
2401 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2402 Reported by Eric Blake.
2404 2006-04-11 Eric Blake <ebb9@byu.net>
2406 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2407 top-level tests after micro-suite has been run. Used in...
2408 (Debugging a successful test, Debugging script and environment),
2409 (Debugging a failed test): ...these new tests. The first of these
2410 is fixed by...
2411 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2412 macro, split out from...
2413 (AT_INIT): ...here, so that using -d also generates a run script.
2414 Document that -d inhibits top-level logging.
2415 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2416 inhibits top-level logging; debug scripts are created.
2418 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2419 check.
2420 * tests/autotest.at (Empty test, Empty check): New test to check it.
2422 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2423 from gcc.
2425 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2427 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2428 the files if a problem appears. Make the empty *.at files
2429 read-only, too. Proposed by Ralf Wildenhues.
2431 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2433 * config/Makefile.am: Add comment to force updated Makefile.in.
2435 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2436 space only patch to this file, this patch causes the Makefile.in
2437 files that include freeze.mk to be updated, and thus have a
2438 newer time stamp again, which in turn makes a pristine CVS
2439 checkout have correct time stamps.
2441 * Makefile.maint (cvs-sv): New macro, to be used..
2442 (config.guess-url_prefix, config.sub-url_prefix)
2443 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2444 point to CVS text checkout of Gnulib files.
2445 (copyright-check): Bump current year.
2446 (announcement): Do not hard-wire `./announce-gen'.
2447 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2448 correctly.
2449 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2450 `chmod +x'.
2451 (wget_files): Update config.guess, config.sub, texinfo.tex by
2452 `wget-update', now that their URLs work again.
2454 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2456 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2457 Problem noted by Paul D. Smith.
2459 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2461 * doc/autoconf.texi: Remove unused words from word list.
2462 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2463 .x-sc_trailing_space: New files.
2465 * doc/standards.texi: Sync from gnulib.
2467 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2468 `LIBOBJDIR' as experimental.
2470 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2471 with a target directory; it's internally implemented as `cp'
2472 anyway, but since Autoconf advertises the possibility to use
2473 a target directory when LN_S is `ln -s', we need to find out.
2474 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2475 analyzed by Keith Marshall <keith.marshall@total.com>.
2477 * THANKS: Update.
2479 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2481 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2482 confdefs.h as-is. In general, if it has backslash-newline or the
2483 like, then it doesn't work either to sort or to remove empty
2484 lines.
2486 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2488 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2490 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2492 * lib/autom4te.in (Automake-preselections): Preselect
2493 _AM_SUBST_NOTMAKE.
2495 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2497 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2498 apostrophe within a single-quoted string, as this is the usual
2499 tradition and is easier to read than '"'"'. Don't rely on the
2500 shell treating "$/" like '$/'. Use a more-consistent indenting
2501 style for the trap.
2503 2006-04-09 Eric Blake <ebb9@byu.net>
2505 * tests/autotest.at (Backquote command substitution),
2506 (Multiline backquote command substitution): Remove mistaken
2507 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2508 applied...
2509 (Parenthetical command substitution, Multiline parenthetical
2510 command substitution): here.
2512 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2514 Import macros from gnulib (often changing their name).
2516 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
2517 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
2518 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
2519 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
2520 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
2521 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
2522 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
2523 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
2524 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
2525 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
2526 The manual mentions Gnulib more prominently.
2527 * doc/autoconf.texi (Gnulib): New node.
2528 (Pointers): Add Gnulib URL.
2529 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
2530 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
2531 Gnulib section.
2532 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
2533 suggest a #define rather than a typedef for _Bool, and mention
2534 Gnulib rather than trying to substitute stdbool code.
2535 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
2536 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
2537 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
2538 AC_STRUCT_DIRENT_D_TYPE.
2539 (Particular Types): Mention stdint.h and inttypes.h as standard
2540 headers too.
2541 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
2542 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2543 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2544 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2545 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2546 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2547 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2548 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2549 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2550 (Coding Style). Don't mention m4_expand_once.
2551 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
2552 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
2553 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
2554 (AC_CHECK_FUNCS): Use it.
2555 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
2556 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
2557 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
2558 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
2559 (AC_HEADER_ASSERT): New macro.
2560 (AC_HEADER_STDBOOL): Don't assume "#error" works.
2561 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
2562 Catch a bug in an HP-UX C compiler.
2563 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
2564 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
2565 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
2566 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
2567 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
2568 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
2569 New macros.
2571 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
2572 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
2574 2006-04-08 Stepan Kasal <kasal@ucw.cz>
2576 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
2577 of the warning introduced by the 2001-08-28 change.
2579 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
2580 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2582 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
2583 variables shall be overriden by the cache.
2584 * tests/torture.at (AC_ARG_VAR): Test also with a first value
2585 that contains braces.
2587 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2589 Revert the patch from 2006-04-01 and only improve
2590 _AS_DETECT_BETTER_SHELL:
2592 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2593 skip nonexistent directories.
2594 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2595 only shell candidates which exist.
2596 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2597 * lib/autotest/general.m4 (AT_INIT): No need to give three
2598 parameters to _AS_PATH_WALK.
2600 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2601 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2603 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2604 distinguish m4sugar macros.
2605 * tests/tools.at (autoupdating with aclocal and m4_include):
2606 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2607 test case by Noah Misch <noah@cs.caltech.edu>.
2609 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2611 Revert my change from 2006-03-17, in other words:
2612 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2613 and DUALCASE=1.
2614 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2615 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2616 it is set.
2618 2006-04-07 Eric Blake <ebb9@byu.net>
2620 * doc/autoconf.texi (Programming in M4sh): Document that
2621 AS_MKDIR_P exits the script on failure.
2622 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2624 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2626 * config/elisp-comp, config/install-sh, config/mdate-sh,
2627 config/missing, config/mkinstalldirs: Sync from Automake.
2629 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
2630 from Automake.
2632 * doc/make-stds.texi: Sync from gnulib.
2634 2006-04-06 Eric Blake <ebb9@byu.net>
2636 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2637 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2638 2006-04-01.
2640 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
2641 Eric Blake <ebb9@byu.net>,
2642 Paul Eggert <eggert@cs.ucla.edu>,
2643 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2645 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2646 whether `set' quotes correctly: redirect stderr of the tested
2647 `set', and use a subshell, for Ultrix; use `sed' instead of
2648 `grep' for zsh `set' which may write binary output; match only
2649 at the beginning of a line, to avoid false positives.
2650 In order to avoid false positives by unrelated variables with
2651 multiline content, put the dump algorithm in a subshell and
2652 unset all variables containing newlines (except some which are
2653 special to the shell). Warn about cache variables that are
2654 unset.
2656 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2658 * config/config.guess, config/config.sub, config/texinfo.tex:
2659 Sync from upstream.
2661 * tests/mktests.sh: Reword comments.
2663 * tests/mktests.sh: Only skip internal macros starting with
2664 `_AC_' or `__AC_'. Noted by Stepan Kasal.
2665 Update exclusion lists for the test suite to this end:
2666 (AC_ARG_VAR): Do test this now.
2667 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
2668 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
2669 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
2670 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
2672 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
2673 shell issue with double-quoted command substitutions of native
2674 commands.
2675 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
2676 Marshall.
2678 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
2679 no file matches the glob, discard the warning, set `nullglob'.
2680 (syntax-check): Likewise.
2681 (sc_cast_of_x_alloc_return_value): Likewise.
2682 (sc_cast_of_alloca_return_value, sc_error_exit_success)
2683 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
2684 (m4-check): Likewise.
2685 (sc_system_h_headers): Do not print rule on execution.
2686 (sc_tight_scope): Do not fail for non-existing `src' directory.
2687 (sc_changelog): Skip the Copyright footer.
2688 * lib/autoconf/lang.m4: Remove trailing space.
2690 * lib/autoconf/status.m4: More replacements to
2691 <tab><space> where this makes sense.
2693 2006-04-06 Stepan Kasal <kasal@ucw.cz>
2695 * tests/Makefile.am (maintainer-check-posix):
2696 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
2698 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to

2714 for --help from Cygnus `configure.'
2716 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

2772 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
2773 (exclude_list): Exclude empty macros.

2857 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2858 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2859 ac_file to the name of the default output file and call
2860 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2861 initial `rm' of the candidate files...
2862 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2863 the same list in subsequent `rm' calls, and for the temporary

2866 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2867 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2868 no longer needed) by libtool. Make it a cache check.
2869 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2870 copied here by mistake.
2871 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2872 _AC_COMPILER_EXEEXT.

2909 subordinate tools.
2910 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
2911 * doc/autoconf.texi (autoreconf Invocation): Document it.
2913 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

2948 switch all of them on and of when necessary. Fixes the bug when
2949 m4sugar macros (e.g., m4_define) were expanded after the first

3616 2005-10-24 Stepan Kasal <kasal@ucw.cz>
3618 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
3619 conftest.o, to see whether the compiler really obeys; rm the object
3620 file before and after the test and register it with ac_clean_files.
3621 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3623 2005-10-21 Stepan Kasal <kasal@ucw.cz>
3625 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
3626 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
3627 code so that the most common case requires less forks.
3629 2005-10-20 Stepan Kasal <kasal@ucw.cz>
3631 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
3632 not portable; thanks to Paul Eggert and Alexandre.
3634 * NEWS: Fix an old typo.
3636 2005-10-20 Jim Meyering <jim@meyering.net>
3638 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
3639 the latter'', in two places.
3641 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
3643 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
3644 AC_LANG_PROGRAM, fixing a typo. Don't give details about
3645 the inner workings of AC_LANG_FUNC_LINK_TRY.
3646 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
3647 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
3648 by the function rather than ignoring it.
3649 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
3650 comparing its address. Intel's interprocedural optimization was
3651 outsmarting the old heuristic. Problem reported by
3652 Mikulas Patocka.
3654 2005-10-19 Stepan Kasal <kasal@ucw.cz>
3656 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
3658 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
3660 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
3661 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
3663 2005-10-04 Stepan Kasal <kasal@ucw.cz>
3665 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
3666 before removing it (chmod -R u+rwx); there are three instances of this.
3668 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3669 Stepan Kasal <kasal@ucw.cz>
3671 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3672 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3673 make its content writable before removing it. Remove an errorneous
3674 comment from the end, where the logs of the failed tests are copied
3675 to the main log file.
3677 2005-09-27 Stepan Kasal <kasal@ucw.cz>
3679 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
3680 in case the computer is too quick. Double quote the configure.ac
3681 snippets.
3683 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
3684 problems if the testsuite were running too fast.
3686 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3688 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3689 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3690 (which belong to Xt, not X itself). See Debian bug 327655.
3691 * NEWS: Mention this.
3693 2005-09-07 Stepan Kasal <kasal@ucw.cz>
3695 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
3697 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
3699 * config/move-if-change: Don't output "$2 is unchanged";
3700 suggested by Ben Elliston. Handle weird characters correctly.
3702 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3704 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3705 calls, so that the final expansion of this macro is shorter.
3706 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3707 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3708 the cleanup there. Use AS_VAR_* macros, to be more general.
3709 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3711 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3713 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
3715 2005-09-01 Stepan Kasal <kasal@ucw.cz>
3717 * doc/autoconf.texi (Configuration Headers): Add an index entry
3718 for AH_HEADER.
3720 2005-08-26 Pavel Roskin <proski@gnu.org>
3722 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
3723 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
3724 running xmkmf.
3726 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
3728 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3729 The previous patch didn't work, so try a better one.
3731 2005-08-26 Stepan Kasal <kasal@ucw.cz>
3733 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3734 in the example. Reported by Bruno Haible.
3735 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3736 "if $undefined_var;" succeeds with my shell.
3738 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
3739 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
3740 but change the m4_divert_text to m4_divert_once.
3742 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
3744 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3745 Work around bug in Solaris /usr/xpg4/bin/awk.
3746 The bug is present in at least Solaris 8 through 10.
3748 2005-08-24 Stepan Kasal <kasal@ucw.cz>
3750 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
3751 some evil values and relying on the fact that $* concatenates the
3752 parameters by the first character from IFS.
3754 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3755 Stepan Kasal <kasal@ucw.cz>
3757 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
3758 first header appears, define AH_HEADER.
3759 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
3760 Update limitations about when to call AC_CONFIG_HEADERS.
3761 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3762 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3763 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3764 ``Configuration Actions''; fix their index entries.
3766 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3767 options correctly. Process N-M as M-N if M is smaller than N.
3768 Process ranges correctly so that N-N will run only N.
3769 Sort and uniquify the tests that will be run. If there is more
3770 than one test, reinsert the banners for the tests.
3771 * tests/autotest.at (Keywords): Unmark XFAIL.
3773 2005-08-23 Stepan Kasal <kasal@ucw.cz>
3775 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
3776 before passing the macro name to AH_TEMPLATE.
3778 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3779 now opens log after option processing; in particular, --version
3780 and --help do not touch config.log.
3782 * Makefile.maint: Revert the change from 2005-08-12.
3784 2005-08-22 Stepan Kasal <kasal@ucw.cz>
3786 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
3787 common code to...
3788 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
3790 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3792 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
3793 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
3794 Language cleanup.
3796 * doc/autoconf.texi (Defining Symbols, Changed Results):
3797 Prepend to LIBS, not append, in examples.
3799 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3801 When building in place, set srcdir="."; suggested by Tim Van Holder.
3803 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3804 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3805 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3806 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
3807 does not mean "no --srcdir option".
3809 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3811 * tests/autoscan.at (autoscan): New file.
3812 * tests/suite.at: Use it.
3813 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
3814 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
3816 * tests/autotest.at (Keywords): Test keywords combinations.
3818 2005-08-12 Stepan Kasal <kasal@ucw.cz>
3820 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
3821 add "2>&1"; gzip 1.2.4 prints help on stderr.
3823 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3825 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
3826 was pushdef'ed twice while popped only once. Push it only once.
3827 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
3829 2005-07-26 Stepan Kasal <kasal@ucw.cz>
3831 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
3832 prefixed by mere "===", not "configure: === ".
3834 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
3836 * Makefile.maint: Update from Bison.
3838 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3839 "<tab>" in comment, so that the point is understandable.
3841 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3843 Rewrite substantial part of lib/autoconf/status.m4.
3844 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3845 and CONFIG_COMMANDS are not processed in four separate loops.
3846 Instead, there is one main loop. This alows that the common code
3847 is expanded only once, thus config.status (and configure) is smaller.
3849 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3850 the AC_LIST_FILES and cousins macros are no longer used.
3852 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3853 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3854 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3855 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3856 contain the initialization, nor the for loop, nor the associated
3857 commands; all these go to ...
3858 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3859 _AC_OUTPUT_CONFIG_STATUS.
3860 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3861 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3862 (_AC_OUTPUT_FILE): The creation of the sed script ...
3863 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3864 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3865 _AC_OUTPUT_MAIN_LOOP.
3866 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3867 _AC_CONFIG_COMMANDS): Use ...
3868 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3869 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3870 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3871 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3872 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3873 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3874 ... new macros.
3875 (_AC_CONFIG_UNIQUE): Update.
3876 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3877 Replaced by this ...
3878 (_AC_LIST_TAGS): ... new common macro.
3879 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3880 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3881 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3882 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3883 this didn't belong to the `config commands' section.
3884 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3885 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3886 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3887 to the `config commands' section either.
3888 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3889 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3891 ... and many changes to the comments nearby.
3893 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3894 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3895 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3896 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
3897 (#define header templates): The comment at the top of the generated
3898 header now includes the name(s) of the source file(s).
3900 Several unrelated small changes:
3902 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
3903 parameter to AC_DIAGNOSE.
3904 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
3905 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
3906 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
3907 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
3908 with AU::AC_OUTPUT.
3909 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
3910 in AC_OUTPUT doesn't double-quote it either.
3911 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
3912 parameters.
3914 2005-07-10 Stepan Kasal <kasal@ucw.cz>
3916 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
3917 versions of Portland Group compiler produce single- and double-quoted
3918 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
3919 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3921 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3923 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3924 This is a corrected version of yesterday's patch.
3926 2005-07-07 Stepan Kasal <kasal@ucw.cz>
3928 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
3929 path, too; insert a "===" to emphasize the line.
3931 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
3932 ac_cv_build_alias to ac_build_alias.
3933 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3935 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3936 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3937 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3938 (AC_ARG_VAR): ... here.
3939 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3940 target_alias.
3942 Keep a list of all precious variables and process them with one simple
3943 for loop, instead of expanding all commands, or, OTOH, complicated
3944 processing of output of "set".
3945 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3946 variable names in new macro...
3947 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
3948 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
3949 a loop to assign all ac_env_* and ac_cv_env_* variables.
3950 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3951 to INIT_PREPARE.
3952 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3953 its value to shell variable ac_precious_vars and call
3954 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
3955 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
3956 _AC_ARG_VAR_VALIDATE.
3958 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
3959 and the AC_SUBSTs ...
3960 (AC_INIT): ... here.
3962 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
3963 the ac_subst_files section in config.log.
3965 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

3974 Fix problems reported by Nicolas Joly.
3975 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
3976 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3977 They are generated by the Tru64 v5.1B shell.
3979 2005-07-05 Stepan Kasal <kasal@ucw.cz>
3981 Fix my changes from 2005-07-01; reported by Noah Misch.
3982 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
3983 description, the macro now accepts only a single tag.
3984 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
3986 Fix cases when the varsions of Autoconf and Autotest don't match.
3987 Reported by Noah Misch.
3988 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
3989 at_top_builddir, for compatibility with older autotest.
3990 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
3991 is not set, use at_top_builddir, for compatibility with older
3992 versions of autoconf.
3994 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
3996 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
3997 Problem reported by Patrick Welche.
3999 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4001 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4002 sed substitution command, so that we allow | in program prefixes
4003 and program suffixes. (& is a problem anyway; we're not fixing
4004 that here.)
4005 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4006 configure_input, top_builddir, srcdir, etc.
4007 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4008 PATH_SEPARATOR in AUTOTEST_PATH.
4010 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4012 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4013 for loop over config.site files using `set', to allow
4014 directory names containing IFS characters.
4016 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
4018 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4019 directories with weird names. Apparently some people like living
4020 on the edge. However, improve the test that "pwd" actually does
4021 report a name for the working directory.
4022 * NEWS: Remove the claim that we test for funny chars in dir names.
4024 2005-07-01 Stepan Kasal <kasal@ucw.cz>
4026 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
4027 replaced ...

4036 about #include <config.h>.
4037 (Generic Functions): Mention the Gnulib project.
4038 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
4040 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4041 document to output the default config_* lists to config.status.
4042 Don't recognize option --file, if the functionality is not there.
4043 Likewise for --header; moreover, recognize --he and --h as shortcuts
4044 for --help in that case.
4046 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4047 matches the order of execution. No code changed.
4049 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4051 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
4052 single-quoted -cmdline argument in Portland Group compiler.
4053 Reported against LAM by Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4055 2005-06-30 Alexandre Duret-Lutz <adl@gnu.org>

4062 descriptors to child processes; reported by Norman Gray.
4064 2005-06-29 Stepan Kasal <kasal@ucw.cz>
4066 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
4068 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
4069 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4070 (AC_SUBST): Call it.
4071 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4072 the directory specific variables; but don't call it for configure_input.
4074 2005-06-28 Derek Price <derek@ximbiot.com>
4076 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4077 addition.
4079 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4081 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4082 directory have inherent problems with special characters like spaces,
4083 due to limitations in Make syntax. Problem reported by Alexandre
4084 Duret-Lutz.
4085 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
4086 Also, fix Tru64 porting problem with shell patterns,

4098 from Justace Clutter.
4099 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4100 variable into diagnostic. Make the diagnostic an error, not a warning,
4101 because we really don't support spaces and suchlike in dir names.
4102 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4103 Don't worry about backslashes in srcdir; it can't happen now.
4104 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
4105 Simplify ac_optarg handling.
4106 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

4114 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
4116 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4117 that '\|' is not allowed in BREs; recommend using newline separated
4118 list of patterns instead of multiple -e options.
4120 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4122 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

4130 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4131 b, t, r, w commands require single space, while : cannot have any.
4132 (Special Shell Variables): Fix sed code this in the example.
4133 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4134 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4136 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4137 expand to the empty list. Don't use two pairs of m4_changequote,
4138 it's not necessary.
4140 2005-06-20 Derek Price <derek@ximbiot.com>
4142 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4144 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4146 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4147 * doc/autoconf.texi:
4148 Don't mention Solaris versions so much, if a
4149 problem is common to all extant versions of Solaris. Say "SunOS
4150 4" instead of "SunOS" for SunOS 4.
4151 (awk): Mention more of the limitations of traditional Awk.
4152 (cat): Don't talk about cat -v.
4154 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
4156 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
4157 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
4158 but the implementation is entirely different and is designed
4159 to be compatible with glibc strverscmp.
4160 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4162 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4163 on Mac OS X 10.4 reported by Peter O'Gorman in:
4164 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
4165 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
4166 Use shell builtins rather than 'expr', to work around expr bug.
4168 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4170 * doc/autoconf.texi: "filesystem" -> "file system".
4171 "behaviour" -> "behavior".
4172 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
4173 * lib/autoconf/general.m4: Omit blank after ":" sed command,
4174 as per POSIX.
4175 * lib/m4sugar/m4sh.m4: Likewise.
4176 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
4177 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4179 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4180 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4181 to update the man page. That way, we don't have to check in new
4182 man pages every month.
4184 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4185 quotes and backslashes. Patch from Derek Price.

4190 AS_TR_SH.
4192 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4194 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4195 -u, since it outputs chatter if the input files are the same.
4196 Problem reported by Ralf Menzel.
4198 2005-06-08 Derek Price <derek@ximbiot.com>
4200 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4201 renaming them since they are about to be redefined anyhow.
4203 2005-06-08 Derek Price <derek@ximbiot.com>
4205 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4206 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4207 Move m4_undefine to alphabetical order.
4209 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4211 * README: Recommend GNU M4 1.4.3 or later.
4212 * doc/autoconf.texi (Introduction): Likewise.
4213 Reword to avoid some formatting glitches.
4214 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4215 Clarify explanation of HP compiler bug.
4216 Redo example output tp match current CVS snapshot.
4217 Use @example.org in email addresses when the examples
4218 might get inadvertently cut-and-pasted into user code.
4219 Remove example of autom4te usage that doesn't seem to work now.
4220 Use modern AC_INIT (except when the example is meant to be
4221 shown with Autoconf 2.13).
4222 Update ksh info for Solaris 9 and later.
4223 KB -> kB.
4224 Modernize description of Automake versions a bit.
4225 Don't claim a future version of Autoconf is near.
4226 * doc/install.texi: Reword to avoid some formatting glitches.
4228 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4230 * doc/autoconf.texi: Add [] to examples, so that the manual
4231 follows its own advice about quoting better.
4232 Reword to avoid some formatting glitches.
4233 * doc/installt.exi: Reword to avoid some formatting glitches.
4235 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4236 Tru64 ksh pattern matching bug. Reported against Libtool by
4237 Albert Chin <libtool@mlists.thewrittenword.com> and
4238 Nicolas Joly <njoly@pasteur.fr>.
4240 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4242 m4_cdr of one-member list was [[]] (one-member list containing an
4243 empty string) instead of [] (an empty list. Callers were skewed to
4244 match this misbehaviour. As a consequence of this:
4245 - m4_foreach([x], [], [foo]) expanded to `foo', while
4246 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4247 This bug has been fixed:
4249 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4250 expand to an empty string; print error msg if called without
4251 an argument list.
4252 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4253 misbehaviour; handle [] and [[]] correctly.
4255 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4257 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
4258 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
4259 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4261 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4263 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4264 swallow records with more than 99 fields.
4265 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4266 parse the long line.
4268 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4270 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4271 swallow literals longer than 399. Reported by Ralf Wildenhues.
4272 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4273 to workaround this limitation.
4275 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4277 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4278 to gfortran, and make these the first two compiler names
4279 checked (following the general autoconf preference for gcc).
4281 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4283 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4284 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4285 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4287 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4289 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4290 expression of unbounded size when processing the --list
4291 option. This runs afoul of a limit of 399 bytes per regular
4292 expression on AIX. Problem reported by Ralf Wildenhues.
4294 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
4296 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
4297 * doc/autoconf.texi (Particular Headers): Reword example
4298 for multiline stdbool replacement.
4299 (Setting Output Variables): Reword text a bit. Don't
4300 give all the details about |#_!!_#|.
4301 Reword description of line replacement.
4303 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4305 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4306 now contain newlines, and substituted files must be referenced on
4307 a line alone; the sed scripts to substitute them are now very
4308 different.
4309 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4310 commands can be put in a sed script portably.
4311 * doc/autoconf.texi (Setting Output Variables): Document above
4312 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4313 use of multiline substitution.
4314 * tests/torture.at: No longer expect substitution of newline to fail.

4323 * tests/local.at: Don't attempt to check for negated character
4324 classes in shell scripts. The test was too brittle.
4326 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4328 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4329 * doc/autoconf.texi (Limitations of Builtins): Document this
4330 limitation.
4332 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4334 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4335 common code; used in many places in the tree.

4337 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4339 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4341 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4342 messages when ac_unique_file is not found.
4343 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4344 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4345 commands, for consistency with AC_MSG_ERROR and such.
4347 * bin/autoconf.as: Make more use of "shift 2" in option processing.
4349 * bin/Makefile.am: Merge the two rules for creating scripts.

4357 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4359 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4360 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4361 (ac_top_builddir): ... this ...
4362 (ac_top_build_prefix): ... to this; the old name is also kept, for
4363 backward compatibility.
4364 (ac_top_builddir_sub): New variable, without the trailing slash,
4365 always nonempty.
4366 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4367 * doc/autoconf.texi (Configuration Actions): Rename
4368 ac_top_builddir to ac_top_build_prefix.
4369 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
4370 at_top_builddir to at_top_build_prefix.

4378 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4380 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4381 argument to m4_foreach. I guess it was necessary in the past,
4382 but I think it's a no-op now.
4384 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4386 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4387 ``cat <<_ACEOF'' commands to one.
4388 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4389 * lib/autoconf/status.m4: On various places, use expr instead of
4390 ``echo|sed.''
4391 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4392 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4393 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4394 a range.
4395 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4396 the wrong patterns between ``case'' and ``esac.'' The previous
4397 code had false positives.
4399 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4401 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4402 as on 2005-05-02.
4403 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

4466 quoting rules. Problems noted by Stepan Kasal.
4467 Also, throughout this document, be more careful about white space.
4468 "blank", "white space", and "space" all have different meanings
4469 and we should be careful to say what we mean.
4471 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4473 Fix C++ related problems reported by Werner Lemberg.
4474 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

4516 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4518 * doc/autoconf.texi (External Software): Quadrigraphs are not
4519 processed correctly in AS_HELP_STRING; avoid this in the examples.
4520 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4521 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4522 comment and reduce m4_default([foo], []) to [foo].
4523 (m4_strip): Update the explanation.
4525 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4527 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4528 Remove core.conftest.* too; it's generated by Tru64 5.1.
4529 Problem reported by Jennis Pruett.
4530 * lib/autoconf/functions.m4
4531 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4532 Don't bother to remove core files; AC_RUN_IFELSE should do that
4533 for you.
4535 2005-04-19 Stepan Kasal <kasal@ucw.cz>
4537 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

4544 2005-04-15 Stepan Kasal <kasal@ucw.cz>
4546 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
4547 the comment.

4554 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
4556 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
4557 as well as configure.in. Problem reported by Gregorio Guidi.
4559 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
4561 * doc/autoconf.texi (Particular Functions): Use gnulib's current
4562 pattern for alloca snippet.

4575 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
4577 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4579 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4580 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4581 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4582 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4583 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4585 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4587 * NEWS: The configure command now warns you if you attempt to use
4588 a directory whose name contains a special character like space,
4589 newline, or "\".
4590 * doc/autoconf.texi (Installation Directory Variables): Allow
4591 "," in file names. Do not use \@; it's not a portable regexp.
4592 * bin/Makefile.am (edit): Likewise.
4593 * lib/Makefile.am (edit): Likewise.
4594 * tests/Makefile.am (edit): Likewise.
4595 * tests/semantics.at: Likewise.

4599 * doc/autoconf.texi (File System Conventions): Warn about
4600 unportable file names.
4601 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4602 (AC_INIT): Use it.
4603 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4604 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4605 ac_pwd, and quote srcdir.
4606 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4608 * doc/autoconf.texi: Fix some systematic formatting problems.
4609 ".)" needs a following @: if not at the end of a sentence, and
4610 similarly for "!)". "etc." should be preceded by a comma.
4611 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4613 2005-03-22 Bruno Haible <bruno@clisp.org>
4615 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4616 argument is often called 'build-aux'.
4618 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4620 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4621 macro AC_TRY_LINK is obsolete.
4622 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4623 `AC_CONFIG_FILES'.
4625 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4627 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4628 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4629 from a Common Lisp's `cl'.
4630 (AC_PROG_CXX): Behave according to the documentation: don't
4631 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4632 make the variable CCC precious; use `cl.exe', not `cl'.
4634 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4635 Alexandre Duret-Lutz <adl@gnu.org>
4637 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4638 /dev/null, as "configure" shouldn't read stdin, and this insulates
4639 us from problems (e.g., when testing for "cl"). Also, do this
4640 redirection before invoking "hostname" or "uname", and keep the
4641 original input stream available via...
4642 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4643 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4644 bother with "</dev/null" since it's now done at the top of
4645 'configure'.
4646 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4647 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

4653 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4655 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4656 newline if neither \c nor -n work, as that would output two
4657 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4659 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4661 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4662 This causes that any required macros inside will get before the if.
4663 * doc/autoconf.texi (autom4te.cache): A typo.
4665 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4667 Undo previous change, except keep the change to
4668 lib/autoconf/programs.m4 that replaced grep with shell
4669 pattern-matching. This is because net-snmp configure reads stdin.
4670 Reported by Noah Misch.
4672 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4674 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4675 from /dev/null, as "configure" shouldn't read stdin, and this
4676 insulates us from problems (e.g., when testing for "cl").
4677 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4678 before invoking "hostname" or "uname".
4679 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4680 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4681 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4682 "</dev/null" since it's now done at the top of 'configure'.
4683 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4684 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4685 Also, replace grep with shell pattern-matching, to save a process.
4687 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4689 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4690 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4691 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4692 compiler.
4694 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4696 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4697 grep -q isn't portable. Improve grep -s explanation.
4698 Problem reported by Dan Manthey.
4700 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4702 * doc/autoconf.texi (Special Shell Variables): Clarify
4703 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4705 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4707 * doc/autoconf.texi: Use @acronym for DJGPP.
4708 Fix some @code's that should have been @env's, and vice versa.
4709 Sort environment variable names.
4710 Mention that shells no longer inherit IFS.
4711 Don't recommend PATH_SEPARATOR=';' so strongly.
4712 Mention that $RANDOM might expand to the empty string.
4713 "symlink" and "soft link" -> "symbolic link".
4714 Improve mktemp description (reported by Bruno Haible).
4716 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
4718 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
4719 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
4720 Likewise.
4721 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
4722 Likewise.
4724 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
4726 * NEWS: Mention AT_COPYRIGHT.
4728 * tests/local.at (AT_CMP): Use diff directly on input files rather
4729 than copying them.
4731 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
4732 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
4734 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4735 and Paul Eggert <eggert@cs.ucla.edu>

4744 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
4745 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
4746 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
4747 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
4748 (Standard regular expressions): New test.
4749 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
4750 excess test name quoting.
4751 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
4752 CPPFLAGS to `configure' instead of setting it in `configure'.
4754 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
4755 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
4756 on some platforms.
4758 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
4759 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

4767 * tests/c.at (Extensions): Do not exit early.

4787 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
4789 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
4790 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4792 Try not to generated lines of unlimited length, as POSIX places a
4793 2047-byte limit on line length of portable text files.
4794 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
4795 Use newline as a separator, not space.

4798 space.

4802 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to

4804 are restored after function return.
4806 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
4808 * doc/autoconf.texi (Special Shell Variables): Mention _,
4809 BIN_SH, DUALCASE. Say that variables other than "status" are safe
4810 if they contain a lower-case letter. The DUALCASE problem was
4811 reported by Ralf Wildenhues.
4813 * bin/autoconf.as: Don't exit with status 0 after write failure
4814 with --help or --version.
4815 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

4821 Unicos 9 sed limitations.
4822 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

4826 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
4828 * man/Makefile.am (.x.1): Go back to the simple solution, but take
4829 care to echo the commands, so the user knows what's going on.
4830 Modified from a suggestion by Stepan Kasal.
4832 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

4840 Based on a proposed patch by Ralf Wildenhues.
4842 * man/Makefile.am (.x.1): Make sure the required generated files
4843 are up to date. Problem and original solution proposed by Stepan Kasal.
4844 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
4845 implicit-man-prerequisites): New rules, used by the above.

4851 2005-01-29 Stepan Kasal <kasal@ucw.cz>
4853 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4854 Update the long comment explaining it.
4856 m4_require no longer writes an ``is required by'' line to the
4857 execution stack. It contains only one bit of non-redundant
4858 information: that the macro was required, not called. And even
4859 this bit is useless in most situations: have you ever met a macro
4860 which both calls and requires the same macro?
4862 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4863 (_m4_defun_pro_outer): ... only via this macro, for the outermost
4864 macro.
4865 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
4866 (m4_expansion_stack_pop): Remove the misplaced comment.
4867 (m4_require): Don't put the ``is required by'' line to the
4868 execution stack; slightly improve the out-of-a-defun error message.
4869 (_m4_divert_grow): New macro, counter for the temporary diversions.
4870 (_m4_require_call): Use it.
4871 * tests/m4sugar.at (m4_require): Expect output without the
4872 ``is required by'' messages.
4874 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4876 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4877 rather than x for expr.
4879 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
4880 this is safe.
4881 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

4893 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
4894 from masters, so that FileUtils.pm's update_file provide --force
4895 support.
4896 * bin/autoheader.in: Pass $force to update_file so that
4897 config.h.in is always recreated when --force.
4899 2005-01-24 Stepan Kasal <kasal@ucw.cz>
4901 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
4903 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
4905 * doc/autoconf.texi (Limitations of Builtins): Clarify that
4906 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
4908 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
4910 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
4911 Warn about newline stripping in `` and $(). Update Solaris
4912 version to 9.
4913 (Limitations of Builtins): Use expr "X...", not expr "x...", as
4914 X insulates us from future changes to Posix.
4915 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
4916 stripping.
4918 2005-01-19 Stepan Kasal <kasal@ucw.cz>

4936 ulongval to be static, to avoid unwanted GCC warning. Problem
4937 reported by Michael Jennings via Daniel Reed; see
4938 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
4940 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
4942 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

4947 new variables.
4949 2005-01-04 Noah Misch <noah@cs.caltech.edu>
4951 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
4952 not seem to work, assume it does set $(MAKE).
4953 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
4955 2005-01-03 Stepan Kasal <kasal@ucw.cz>
4957 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

5282 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5283 "char c = '\200';" rather than "char c = 0x80;" as the

5431 * README: Add advice about m4 1.4.2.
5433 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5434 texinfo.tex for now (done by hand now).
5435 * Makefile.maint (wget_files, cvs_files):
5436 Remove ansi2knr.c; nobody uses it.
5437 (ansi2knr.c-url_prefix): Remove.
5438 (cvs-update): Fix test for failure. I don't know why it ever
5439 worked...
5441 * doc/autoconf.texi: Update URLs, some of which went stale.
5442 Use @uref rather than @href.
5444 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5445 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5447 * config/config.guess, config/config.sub, config/elisp-comp,
5448 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5449 doc/fdl.texi, doc/standards.texi: Sync with master copy.
5451 * NEWS, TODO, configure.ac, bin/autoscan.in,
5452 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
5453 doc/install.texi, lib/Autom4te/Configure_ac.pm,

5457 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
5458 tests/tools.at, tests/torture.at:
5459 Use "file name" rather than "filename" or "path",
5460 to be consistent with the terminology of the GNU coding standards.
5462 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5464 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5465 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5466 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5467 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5469 More fixes to support spaces in the name of the build directory.
5470 This isn't a complete fix but it's an improvement.
5472 * bin/autoconf.as (autom4te_options): New var.
5473 Use it instead of appending to AUTOM4TE, so that we can allow
5474 spaces in the build directory's absolute name.
5475 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5476 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
5477 AT_CHECK_NOESCAPE): Likewise.
5478 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
5479 main program): Likewise.
5481 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
5483 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
5484 From Ralf Corsepius in:
5485 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
5487 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
5489 * doc/autoconf.texi (Function Portability): Document isinf and
5490 and isnan. From a suggestion by Kevin Ryde.
5492 * lib/Autom4te/General.pm (END): Return correct exit status even
5493 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5495 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5497 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5498 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5499 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5501 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5503 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5504 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5505 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5506 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5507 * lib/autom4te.in (Automake-preselections): Preselect
5508 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5510 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5512 * lib/autom4te.in (Automake-preselections): Preselect
5513 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5514 trace them.
5516 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5518 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5519 Tru64.
5520 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5521 Document problem with "`""`" in pdksh POSIX mode.
5523 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5525 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5526 with pdksh, too. Problem reported by Patrick Welche via
5527 Gary V. Vaughan.
5528 * doc/autoconf.texi (Shellology): Note that set -o posix is
5529 useful for pkdsh, too.
5531 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5533 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5534 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5535 Don't fail if ENV or BASH_ENV is readonly.
5536 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5537 etc. are read only. Problem reported by Ludovic Courtes.
5539 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5541 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5542 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5543 (trivial change)
5545 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5547 * doc/autoconf.texi (File System Conventions): Warn about
5548 names like "aux". Problem reported by Eric Blake.
5550 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5551 by zero instead of array size, so that we can use any arithmetic
5552 constant expression (instead of requiring an integer constant
5553 expression). This allows us to test expressions like DBL_MAX <
5554 LDBL_MAX, which didn't conform to the C standard using the old
5555 method.
5556 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5557 now that we can do floating-point tests at compile time.
5559 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5561 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5562 and LDBL_EPSILON, as the resulting expression isn't an
5563 integer constant expression and violates the C standard.
5564 Problem reported by Nelson H. F. Beebe. Also, check
5565 for "L" suffix, and check that long double doesn't have
5566 worse range or precision than double, that mixed-mode
5567 arithmetic doesn't generate a diagnostic, that double
5568 constants fit in long double.
5570 2004-06-03 Kevin Ryde <user42@zip.com.au>
5572 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5573 malloc(0) and realloc(NULL,size).
5575 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5576 Bob Proulx.
5578 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5580 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5581 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5582 by Jim Meyering.
5584 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5586 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5587 can be rewritten using if-then-else. Suggested by Bruno Haible.
5589 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5591 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5592 Problem reported by Stepan Kasal.
5594 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5596 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5597 change). Patch reported by Ralf Wildenhues in
5598 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5600 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5601 function F exists if the compiler and linker let you compile an
5602 expression like (F != 0). Recent versions of GCC optimize away
5603 the reference to F in that case, since every function address must
5604 be nonzero, so the link succeeds even if F does not exist.
5605 Problem reported by Manu in
5606 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5608 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5609 "Unix". Many uses changed.
5610 (Limitations of Builtins): Explain better why the ! command isn't
5611 portable.
5613 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5615 * lib/autom4te.in (Automake-preselections): Preselect
5616 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5618 2004-05-19 Kevin Ryde <user42@zip.com.au>
5620 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5621 referencing AC_FUNC_STRERROR_R.
5623 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5624 note pessimistic assumption when cross compiling.
5626 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5628 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5629 (until 2004) invoked subcommands with sh -e, contra POSIX.
5630 Reported by Kevin Ryde.
5632 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5634 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5635 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5636 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5637 `test -f " /usr/bin/grep"', which _always_ failed.
5638 (AC_PROG_SED): Ditto bogus PATH fix.
5639 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5640 requires that grep correctly supports _multiple_ `-e' options, rather
5641 than stating only that grep should accept `-e'.
5643 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5645 Port to C99, which requires that 'exit' be declared.
5647 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5648 to ensure that stdlib.h is included.
5649 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5650 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5651 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5652 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5653 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5654 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5655 when using 'exit' in a test; C99 requires that 'exit' be declared.
5657 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5659 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5660 now prefers 'grep' implementations that accept -e.
5661 (Limitations of Usual Tools): Describe problems of traditional
5662 egrep and fgrep with long input lines, and of traditional grep
5663 with -e.
5664 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5665 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5666 All callers changed. Append /usr/xpg4/bin to the PATH, for
5667 Solaris.
5668 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5669 the user with complaints about multiple -e options.
5670 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5671 Define it with AC_PROG_GREP.
5672 * configure.ac (AC_PROG_GREP): Add.
5673 * lib/freeze.mk (GREP): New macro.
5675 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5677 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5678 a possible candidate only after all others fail, rather than
5679 consulting it first. This improves backward compatibility by
5680 better reflecting the way shell selection occurred in previous
5681 versions of Autoconf, and should help to avoid triggering latent
5682 problems in other packages, such as the one in Automake where zsh
5683 is not handled robustly:
5684 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5685 Although it is not Autoconf's responsibility to work around
5686 problems in Automake, it nevertheless makes sense to avoid
5687 introducing unnecessary incompatibilites.
5689 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5690 Gary V. Vaughan <gary@gnu.org>
5692 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5693 how deeply nested we are when a suitable tool is found, set the
5694 ac_path_TOOL_found flag.
5695 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5696 nested we are in this macro. Break out of all 3 nested loops if
5697 ac_path_TOOL_found is set.
5699 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5701 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5702 of the _AS_PATH_WALK loop too if GNU flavor is found.
5704 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5706 * doc/autoconf.texi (Limitations of Make): Update documentation
5707 for `$<'. New entry `Long lines', based on a report from Simon
5708 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5709 paragraph about DJGPP, based on a mail from Richard Dawe.
5711 2004-04-20 Paul Eggert <eggert@twinsun.com>
5713 * tests/c.at (C keywords): Don't assume that GCC supports
5714 "restrict" and "inline", as sufficiently-old GCC versions do not
5715 (also, GCC configured to be in pedantic C89 mode does not).
5716 Problem reported by Sumit Pandya in:
5717 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5719 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5720 consider -g to work if it generates warnings when plain compiles
5721 don't. Problem reported by Braden McDaniel in:
5722 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5724 * doc/autoconf.texi (Slashes): New section, to document a problem
5725 reported by Jim Meyering in:
5726 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5728 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5729 linker output files before linking, to work around IRIX 6 linker bug.
5730 Problem reported by Rainer Orth in:
5731 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5733 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5735 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5736 best tool so far counter rely on the tool path variable name to
5737 avoid checks for one tool being affected by the results of running
5738 the length check on a previous tool.
5740 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5741 match expression argument, as different greps have different
5742 regular expression flavours.
5743 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5744 literals.
5745 (AC_PROG_EGREP): Pass 'EGREP$'.
5746 (AC_PROG_GREP): Pass 'GREP$'.
5748 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
5750 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
5751 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
5753 2004-03-29 Paul Eggert <eggert@twinsun.com>
5755 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
5756 Types, Specific Compiler Characteristics, System Services,
5757 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5758 etc. consistently instead of 'long', 'short', 'unsigned' etc.
5759 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
5760 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
5761 Likewise.
5762 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
5763 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
5764 AC_TYPE_OFF_T): Likewise.
5765 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
5766 Likewise.
5768 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
5769 pacify libtool 1.5.2. Fix quoting problems in sed command.
5771 2004-03-28 Paul Eggert <eggert@twinsun.com>
5773 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
5774 now defines HAVE_DECL_TZNAME if it is declared, when
5775 HAVE_STRUCT_TM_TM_ZONE is not defined.
5776 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5777 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
5778 for HAVE_TZNAME.
5780 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
5782 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
5783 superfluous backslashing of quotes (") in sed expressions;
5784 thanks to Paul Eggert.
5786 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
5788 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
5789 Fortran compiler is ifort, also added pghpf; thanks to Nelson
5790 H. F. Beebe for the bug report.
5792 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
5794 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
5795 quoted -cmdline argument in Portland Group compiler (bug
5796 reported by Jeffrey J. Barteet).
5798 2004-03-25 Kevin Ryde <user42@zip.com.au>
5800 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
5801 (Run Time): ... here, where it's now mentioned.
5803 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
5805 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
5806 inherits from language Autoconf-without-aclocal-m4.
5807 (Customizing autom4te): Adjust example; the cache must now be
5808 disabled for language Autoconf-without-aclocal-m4.
5810 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
5811 Nathanael Nerode <neroden@twcny.rr.com>
5813 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
5814 AC_CHECK_TOOLS): Warn if a cross-tool is found without
5815 a prefix.
5816 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
5817 AC_CHECK_TARGET_TOOLS): New macros.
5818 * doc/autoconf.texi (Generic Programs): Document
5819 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
5820 AC_CHECK_TARGET_TOOLS, and warn for future changes
5821 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
5822 AC_CHECK_TOOLS.
5823 (Specifying Names): Document the reason for these future
5824 behavioral changes.
5825 * tests/mktests.sh: Do not generate tests for the
5826 new macros.
5827 * NEWS: Document these changes.
5829 * doc/autoconf.texi: Avoid macros with unbraced arguments,
5830 they make TeX hang up.
5832 2004-03-15 Paul Eggert <eggert@bogus.example.com>
5834 * NEWS: New macro AC_CHECK_ALIGNOF.
5835 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5836 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
5837 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
5838 vowel.
5839 (AC_CHECK_ALIGNOF): New macro.
5840 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
5841 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
5842 those for sizeof.
5844 2004-03-03 Paul Eggert <eggert@twinsun.com>
5846 * bin/Makefile.am (edit): Don't use $< in a context where
5847 POSIX doesn't require support for it. Use $@.in instead.
5848 Problem reported by Anthony N. Frasso in
5849 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
5850 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
5852 2004-02-23 Gary V. Vaughan <gary@gnu.org>
5854 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
5855 from the next generation of Libtool.
5856 * lib/autom4te.in (Autoreconf-preselections): Ditto.
5858 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5860 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
5861 is not always thread-safe. Report from Nathanael Nerode.
5863 2004-02-18 Paul Eggert <eggert@twinsun.com>
5865 Fix a dependencies problem, stemming from a Autoconf 2.59 build
5866 problem on QNX reported by Stephen Rasku in
5867 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
5869 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
5870 $(m4sh_m4f_dependencies); this removes a FIXME.
5871 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
5872 (MAINTAINERCLEANFILES): Split into pieces,
5873 one per related section. Add $(srcdir)/wrapper.in.
5875 2004-02-09 Paul Eggert <eggert@twinsun.com>
5877 * doc/autoconf.texi (Setting Output Variables): Emphasize that
5878 AC_SUBST provides no portable way to escape literal newlines.
5880 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5881 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5882 Darwin uses -lcrt2.o and there's little point to cataloging all
5883 the system variants. Partial fix reported by Andreas Waechter in:
5884 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
5885 for bug reported by Nelson H. F. Beebe in:

5891 suggested by Paul Eggert.
5892 * lib/autoconf/autoupdate.m4: Correct reference to
5893 acobsolete.m4, suggested by Alexandre Duret-Lutz.
5895 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
5897 * bin/autoupdate.in: Define __file__ so that warnings
5898 refer to the correct file.
5899 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
5900 the behavior of the third argument.
5901 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
5902 correctly the behavior of the third argument. Document
5903 what the three macros that AU_DEFUN defines do. Fix
5904 warning message when the third argument includes $0
5905 (reported by Alexandre Duret-Lutz).
5907 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5908 Eric Sunshine <sunshine@sunshineco.com>
5909 Paul Eggert <eggert@twinsun.com>
5911 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
5912 (AS_INIT): Output shell initialization there. Removed optional
5913 parameter. Expand _AS_SHELL_FN_SPY.
5914 (AS_INIT_WITH_SHELL_FN): Removed.
5915 (_AS_SHELL_FN_SPY): New macro.
5916 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
5917 macros.
5918 (AS_SHELL_SANITIZE): Remove loop to find better shell
5919 and documentation for the parameter.
5920 (_AS_DETECT_BETTER_SHELL): Move it here.
5921 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
5922 (_AS_RUN): Move it here, support testing with eval.
5923 (AS_REQUIRE_SHELL_FN): Require shell functions when
5924 it is used.
5925 (_AS_LINENO_WORKS): Put around braces, we do not
5926 trigger the bash bug anymore.
5927 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
5928 use AS_INIT_WITH_SHELL_FN.
5929 * bin/autoconf.in, tests/wrapper.in: Regenerated.
5931 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5933 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
5934 * doc/autoconf.texi: Don't say that the third parameter
5935 is broken.
5936 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
5937 (AU_DEFUN): Honor the third parameter, create autoupdate
5938 macros with AU_DEFINE.
5939 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
5940 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
5941 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
5942 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
5943 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,
5944 AC_ARG_ARRAY, AC_CYGWIN, AC_EMXOS2, AC_MINGW32,

5946 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS,
5947 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
5948 * lib/autoconf/status.m4: Remove FIXME.
5949 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
5950 that the macro is not present anymore in the updated
5951 configure.ac.
5952 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
5953 of autoupdate.
5955 2004-01-28 Paul Eggert <eggert@twinsun.com>
5957 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
5958 copyright years.
5959 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
5960 2003 (except 1997) to the list of copyright years. This undoes
5961 the 2003-05-22 change, which removed the older years from the list.
5962 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
5964 2004-01-27 Gary V. Vaughan <gary@gnu.org>
5965 Albert Chin-A-Young <china@thewrittenword.com>

5968 grep or ggrep program in PATH that accepts as long lines as
5969 possible.
5970 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
5971 AC_PROG_GREP.
5972 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
5973 egrep and fgrep respectively if $GREP -E/-F don't work.
5974 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
5975 _AC_PROG_GREP, and AC_PROG_SED.
5976 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
5977 longest input length accepted by a command.
5978 (AC_PROG_SED): Use it.
5979 * doc/autoconf.texi (Particular Programs): Document the changes.
5980 * NEWS: Updated.
5982 2004-01-27 Paul Eggert <eggert@twinsun.com>
5984 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
5985 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
5986 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
5987 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
5989 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
5990 bin/autoconf.in, config/Makefile.in, config/config.guess,
5991 config/config.sub, config/install-sh, config/mdate-sh,

6002 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
6003 tests/actypes.at: Regenerate and/or sync with original
6004 sources.
6006 2004-01-26 Paul Eggert <eggert@twinsun.com>
6008 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6009 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6010 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6011 not <inttypes.h>. Problem reported by Tim Mooney in
6012 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6013 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6014 Likewise.
6016 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6017 otherwise "make check" fails because it forbids cmp (I guess
6018 because cmp treats files as binary on DOS-like systems).
6020 * tests/mktests.sh: Update copyright date to 2004, since some tests
6021 have changed in 2004.
6023 2004-01-23 Gary V. Vaughan <gary@gnu.org>
6025 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
6026 non-truncating sed or gsed program in PATH.
6027 * tests/acprograms.at: Add it.
6028 * doc/autoconf.texi (Particular Programs): Document it.
6029 * NEWS: Updated.
6031 2004-01-15 Paul Eggert <eggert@twinsun.com>
6033 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6034 -std1 disables some useful extensions on Tru64. Problem reported
6035 by N. Lichtmaier in
6036 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6038 2004-01-14 Paul Eggert <eggert@twinsun.com>
6040 * doc/autoconf.texi (Programming in M4sh): Document that
6041 AS_MKDIR_P succeeds if the destination is a symbolic link
6042 to an existing directory.
6043 (Limitations of Usual Tools): Note that mkdir -p might not
6044 succeed on symlinks to directories.
6046 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6048 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6049 * bin/autoheader.in: Grammar fix in message.
6050 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6051 Test for dir before calling mkdir -p. (trivial changes)
6053 2004-01-13 Eric Blake <ebb9@byu.net>
6055 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6056 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6058 2004-01-10 Jim Meyering <jim@meyering.net>
6060 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6062 2004-01-09 Paul Eggert <eggert@twinsun.com>
6064 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6065 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6066 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6067 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6068 AC_COMPILE_IFELSE, since we now assume our caller invokes
6069 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6070 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6071 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6072 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6074 2004-01-07 Paul Eggert <eggert@twinsun.com>
6076 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6077 `"'...'"`, as it's confusing (and I suspect it may not work on
6078 some platforms). The code was incorrect anyway, as it assumed
6079 that \$ evaluated to itself in that context. Reported by
6080 Alexandre Duret-Lutz.
6082 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6084 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6085 and _LT_AC_TAGCONFIG.
6087 2004-01-06 Paul Eggert <eggert@twinsun.com>
6089 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6090 example, and add more examples. Reported by Eric Sunshine.
6092 2004-01-05 Paul Eggert <eggert@twinsun.com>
6094 * doc/autoconf.texi (Limitations of Usual Tools):
6095 Remove warning against "rm -fr" introduced yesterday; it
6096 was a false alarm.
6098 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6099 autoscan, autoupdate, ifnames): Don't use chmod -w.
6100 * lib/Makefile.am (autom4te.cfg): Likewise.
6101 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6102 "chmod -w".
6104 2004-01-04 Paul Eggert <eggert@twinsun.com>
6105 Paolo Bonzini <bonzini@gnu.org>
6107 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
6108 by doing lineno substitution only on lines containing "$LINENO".
6110 2004-01-04 Paul Eggert <eggert@twinsun.com>
6112 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6113 Use "rm -f" to remove conftest.sed, not plain "rm".
6114 Bug reported by David Relson in
6115 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6117 * Makefile.am (autom4te-update):
6118 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6119 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6120 * doc/autoconf.texi (Guidelines): Likewise.
6121 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

6126 * tests/Makefile.am (clean-local): Likewise.
6127 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6128 srcdir): Likewise.
6129 * doc/autoconf.texi (Limitations of Usual Tools):
6130 Warn against "rm -fr".
6132 2004-01-03 Paul Eggert <eggert@twinsun.com>
6134 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6135 -c -o might not work. From a suggestion by Kevin Ryde.
6136 (C Compiler, Generating Sources, Limitations
6137 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6138 Don't put '-o' after non-options, as POSIX doesn't allow this.
6139 Mention that cc's name might be gcc or c89 or whatever.
6141 2004-01-04 Kevin Ryde <user42@zip.com.au>
6143 * doc/autoconf.texi: Add various further index entries.
6145 2003-12-29 Paul Eggert <eggert@twinsun.com>
6147 * bin/autoreconf.in (autoreconf_current_directory):
6148 Fix typo: mkdir without umask arg.
6150 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6152 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6153 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6154 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6155 explanation clearer.
6157 2003-12-24 Andreas Schwab <schwab@suse.de>
6159 * doc/autoconf.texi (Default Includes): Fix misspelling of
6160 AC_INCLUDES_DEFAULT.
6162 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6164 * configure.ac: Test if sh -n works.
6165 * configure: Regenerate.
6166 * tests/atlocal.in: Store the result here.
6167 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6168 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6169 of explicitly testing.
6170 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6171 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6172 * tests/tools.at (Syntax of the shell scripts): Simplify
6173 using AT_CHECK_SHELL_SYNTAX.
6174 (Syntax of the Perl scripts): Remove definition of
6175 AT_CHECK_PERL_SYNTAX.
6177 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6179 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
6180 stderr to /dev/null.
6181 * bin/autoconf.in: Regenerate.
6182 * bin/wrapper.in: Regenerate.

6186 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
6187 Extracted from AS_SHELL_SANITIZE.
6188 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
6189 macros.
6190 (AS_SHELL_SANITIZE): Move reinvocation code from
6191 _AS_LINENO_WORKS, use it to find out if shell
6192 functions work.
6193 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6194 does not work.
6195 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
6196 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
6197 was called.

6206 * config/announce-gen (&print_locations, &print_signatures)
6207 (&sizes): New.
6208 Use them.

6210 them on the fly.
6212 2003-11-24 Akim Demaille <akim@epita.fr>
6214 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6242 parameter of AU_DEFUN.
6243 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.

6247 the expanded body, consistently with other macros such as AC_USG.
6249 2003-11-17 Paul Eggert <eggert@twinsun.com>
6251 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
6252 into the initial confdefs.h, to work around a bug in NextStep 3.3
6253 patch 3 reported by Eric Sunshine.
6255 2003-11-15 Kevin Ryde <user42@zip.com.au>
6257 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
6258 than $target since the latter is not usual, add guidelines on when to
6259 use or not use the system type.
6261 2003-11-12 Derek Price <derek@ximbiot.com>
6263 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
6264 typo misrepaired by an auto-spellcheck.
6266 2003-11-12 Akim Demaille <akim@epita.fr>

6269 --force-missing unless it actually supports it.
6270 From Debian #219336.
6272 2003-11-12 Akim Demaille <akim@epita.fr>
6274 * configure.ac: Bump to 2.59a.

6283 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE
6284 so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,
6285 and ac_abs_top_srcdir are absolute paths.

6292 2003-11-05 Kevin Ryde <user42@zip.com.au>

6299 handler return type, as per AC_TYPE_SIGNAL.

6311 computing the absolute path to d1 in the source hierarchy: it may
6312 not exist at all. So don't cd into it.
6313 From Alexandre Duret-Lutz.
6314 http://mail.gnu.org/archive/html/bug-autoconf/2003-10/msg00205.html

6418 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
6419 cross test.
6421 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
6423 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
6424 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

6435 Issue a more-informative diagnostic.
6436 Problems reported by Eric Sunshine.
6438 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6440 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6441 -mGLOB_options_string stuff for Intel ifc, which can cause

6465 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6466 cache variable instead of $G77 to decide whether to include -O2,
6467 since $G77 is specific to Fortran 77.

6471 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
6472 free" flag. Re-order flags tested into rough order of popularity.
6474 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6476 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6477 arguments so that it can be used with syntax identical to
6478 AC_PROG_F77, and so that we can more easily decide to
6479 remove/deprecate the DIALECT optional argument in the future if it
6480 proves troublesome.
6481 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
6482 non-freeform-supporting compilers. Document freeform flags.
6484 2003-10-03 Akim Demaille <akim@epita.fr>
6486 * configure.ac: Look for emacs, not macs.

6489 2003-10-03 Akim Demaille <akim@epita.fr>
6491 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.

6496 2003-10-03 Akim Demaille <akim@epita.fr>
6498 * configure.ac: Quotation and formatting changes.

6546 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
6547 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6548 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6549 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6551 2003-09-26 Akim Demaille <akim@epita.fr>
6553 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6554 directory for AC_CONFIG_COMMANDS' first argument exists.
6555 This makes valid the invocation of _AC_SRCPATH that follows.
6556 Reported by Eric Sunshine.
6557 * doc/autoconf.texi (Configuration Commands): Adjust.
6559 2003-09-26 Akim Demaille <akim@epita.fr>
6561 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6562 Reported by Ralf Corsepius.

6566 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6567 arguments.
6568 Actually, use AU_ALIAS.
6569 From Bruno Haible.

6578 2003-09-26 Akim Demaille <akim@epita.fr>
6580 The test suite are sometimes assigning timings incorrectly.
6581 Reported by Henk Krus.
6582 Diagnosed by Nicolas Joly.
6584 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6585 AT_help_all.
6586 Instead of making AT_help a sequence of assignments to grow
6587 $at_help_all, just make AT_help_all be the growing contents of
6588 $at_help_all, and make a single assignment in...
6589 (AT_INIT): here.
6590 (at_times_skip): Flip the meaning and rename as...
6591 (at_times_p): this.
6592 (AT_INIT): When summarizing the test that ran, remove
6593 $at_times_file after use, and check it is present before trying to
6594 use it.
6596 2003-09-25 Akim Demaille <akim@epita.fr>
6598 Version 2.57d.
6600 * bin/Makefile.am (edit): Handle '@configure_input@'.

6602 (ifnames): chmod -w.
6603 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6604 executables, not bin/ executables! Otherwise all the magic needed
6605 to find non installed files is turned off. This caused a failure
6606 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6607 as found in its environment (sent by tests/autoreconf): pointing
6608 to bin/autom4te that could not find its files.
6609 * tests/mktests.sh: Force the replacement of generated files, for
6610 the sake of "mv" program that are interactive when overwriting a
6611 -w file.
6612 * config/install-sh: Upgrade from CVS Automake.
6614 2003-09-23 Paul Eggert <eggert@twinsun.com>

6617 versus test -L issues.
6619 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
6620 Paul Eggert <eggert@twinsun.com>
6622 Trivial change to support GCC's configuration procedure.
6623 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6624 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6625 about inconsistency if the preprocessor is set to give errors for
6626 any warning.
6627 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6629 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

6652 * doc/autoconf.texi (Header Portability): linux/random.h.
6653 From Peter Hendrickson.
6655 2003-09-10 Akim Demaille <akim@epita.fr>
6657 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6658 willing to edit the output files.
6660 2003-09-10 Akim Demaille <akim@epita.fr>
6662 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6663 and AC_FC_FREEFORM.
6664 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6665 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
6667 2003-09-09 Akim Demaille <akim@epita.fr>

6681 Improve the accuracy of the wording about obsolescence.
6682 From a suggestion by Ian Lance Taylor in
6683 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
6685 2003-09-05 Paul Eggert <eggert@twinsun.com>
6687 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6688 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6690 2003-09-04 Akim Demaille <akim@epita.fr>
6692 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6693 AC_FUNC_WAIT3.
6695 2003-09-04 Akim Demaille <akim@epita.fr>
6697 * bin/autom4te.in: Use &fatal where more appropriate than &error.
6698 (freeze): When exiting, use $exit_code.
6699 * lib/autoconf/fortran.m4: Comment changes.
6701 2003-09-04 Akim Demaille <akim@epita.fr>
6703 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
6705 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6707 Add support for newer Fortran dialects. The F77 interface is
6708 unchanged, and continues to support Fortran 77. New FC macros
6709 correspond to all the old F77 macros, with output variables FC,
6710 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6711 available dialect, but older dialects can be specified. There are
6712 new macros AC_FC_SRCEXT to set the source extension, and
6713 AC_FC_FREEFORM to accept free-form source files.
6715 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
6716 New macros.
6717 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

6733 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
6734 Rewrite in terms of the above.
6735 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
6736 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

6742 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
6743 Document problems with timestamp resolution that 'make', 'cp -p', and
6744 'touch -r' have.
6746 2003-08-27 Akim Demaille <akim@epita.fr>
6748 * tests/m4sugar.at (cross_warning): Make sure to enable the
6749 output, so that we can track spurious m4sugar output.
6750 * tests/local.at: Require 2.57.
6751 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
6752 are defaulted by AT_CHECK anyway.
6753 Use AT_CHECK_AUTOM4TE.
6754 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
6755 missing dnl.
6757 2003-08-27 Akim Demaille <akim@epita.fr>
6759 * bin/autoheader.in: Issue the "Using auxiliary..." message only
6760 when -Wobsolete is set.

6794 2003-08-22 Akim Demaille <akim@epita.fr>
6796 Version 2.57b.
6798 * Makefile.cfg (local-checks-to-skip): New.
6799 * Makefile.maint (local-check): Rename as...
6800 (local-checks-available): this.
6801 (local-check): New.
6803 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
6804 * configure.ac: Require Automake 1.7.6.
6806 2003-08-22 Akim Demaille <akim@epita.fr>
6808 Output stack traces in warnings.
6810 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
6811 Replace the former...
6812 (m4_warn): Pass the call stack to _m4_warn.
6813 * bin/autom4te.in: Adjust to output the call stack.
6814 * tests/m4sugar.at (m4@&t@_warn): Adjust.
6816 2003-08-22 Akim Demaille <akim@epita.fr>
6818 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
6819 * bin/autom4te.in: Adjust.
6821 2003-08-21 Akim Demaille <akim@epita.fr>
6823 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
6824 (&verbose): Remove.
6825 (&getopt): Adjust the note and verb channels, depending upon
6826 --verbose.
6827 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
6828 * bin/autoupdate.in: Adjust.
6829 Use &verb, not &verbose.
6831 2003-08-21 Akim Demaille <akim@epita.fr>
6833 * bin/autoheader.in (&parse_args): Use &parse_warnings and
6834 &parse_WARNINGS.
6835 ($help): Use Autom4te::ChannelDefs::usage.
6836 * bin/autoscan.in: Use Autom4te::ChannelDefs.
6837 * lib/Autom4te/General.pm: Don't export error: you don't own it.
6839 2003-08-21 Akim Demaille <akim@epita.fr>
6841 First stab at preserving warnings between calls to autom4te,
6842 including when the cache is used.
6844 There are still several issues: (i) there are too many runs of m4
6845 (one for include, one for warnings, and some more), (ii) warnings
6846 spreading on several lines are not handled gracefully, (iii) the
6847 code meant to have the call stack display for errors does not work
6848 (its handling should move from m4 to autom4te).
6850 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6851 Use them.
6852 (@preselect): Add m4_warn.
6853 ($exit_status): Remove, use $exit_code.
6854 ($help): Use Autom4te::ChannelDefs::usage.
6855 (&handle_m4): No longer define the m4_warnings.
6856 At each run, extract and report the warnings.
6857 Always cache the result, including if the exit status is on
6858 failure, since if nothing changes, we should result in the same
6859 failure, hence we can use the cache.
6860 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6861 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6862 Remove.
6863 (m4_warn): Redefine as a do-nothing: it is its invocation that
6864 matters, as warnings are now reported via traces.
6865 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6866 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6867 the latter reveals calls to the former.
6869 Adjust the tests.
6871 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6873 2003-08-21 Akim Demaille <akim@epita.fr>
6875 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
6876 Use them.
6878 2003-08-21 Akim Demaille <akim@epita.fr>
6880 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
6881 forward order.
6882 * lib/Autom4te/ChannelDefs.pm: Doc typos.
6883 (&parse_warnings): Accept a list of warning requests.
6884 (&usage): Return a string, not a side effect.
6885 (cross): New warning category.
6887 2003-08-21 Akim Demaille <akim@epita.fr>
6889 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
6890 (&require_configure_ac): Accept an optional directory argument.
6891 ($configure_ac): Remove.
6892 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
6893 (&catfile): Remove.
6894 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
6895 * bin/autoscan.in: Adjust.
6897 2003-08-20 Akim Demaille <akim@epita.fr>
6899 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
6900 Reported by Alexandre Duret-Lutz.
6902 2003-08-20 Akim Demaille <akim@epita.fr>
6904 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
6905 * bin/autom4te: Adjust.
6906 In particular, be Autoconf tools are really silent when properly
6907 working, bind the verbosity of the 'note' channel to $verbose.
6908 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
6909 (&xsystem, &contents): Remove, since they are exported by...
6910 * lib/Autom4te/FileUtils.pm: this.
6911 More perldoc.
6912 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
6913 * lib/Autom4te/FileUtils.pm: here.
6915 2003-08-20 Akim Demaille <akim@epita.fr>
6917 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
6918 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
6919 from CVS Automake.
6921 2003-08-20 Akim Demaille <akim@epita.fr>
6923 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
6924 (autom4te-update): New.
6925 * Makefile.cfg (update): Bind autom4te-update.
6927 2003-08-19 Derek Price <derek@ximbiot.com>
6929 * lib/autotest/general.m4: Comment various HELP_* diversions.
6930 (PARSE_ARGS_BEGIN): New section for option parsing related
6931 initialization.

6937 * config/announce-gen, Makefile.cfg: New.
6938 * Makefile.am: Adjust.
6939 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
6941 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
6943 * lib/autom4te.in (Automake-preselections): Preselect
6944 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
6945 and m4_sinclude.
6947 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
6949 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...

6951 * doc/autoconf.texi (autom4te Invocation): Mention
6952 Autoconf-without-aclocal-m4.

6957 RUN-IF-PASS optional arguments.

6966 STDOUT & STDERR arguments.
6968 2003-08-14 Derek Price <derek@ximbiot.com>
6970 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
6971 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
6972 shorter column three. Add DESCRIPTION to log file content.
6974 2003-08-13 Derek Price <derek@ximbiot.com>
6976 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
6977 output.
6979 2003-08-12 Derek Price <derek@ximbiot.com>
6981 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
6982 (AT_CHECK_NOESCAPE): Move core functionality to...
6983 (_AT_CHECK): ...this new macro.
6985 2003-08-07 Derek Price <derek@ximbiot.com>
6987 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
6988 (AT_CHECK_NOESCAPE): ...to this new macro.
6990 2003-07-31 Paul Eggert <eggert@twinsun.com>
6992 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
6993 in Bash 2.01. Problem reported by Brian Gough in
6994 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
6996 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
6998 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
6999 -lcrt1.o, for OS X. (trivial change)
7001 2003-07-07 Paul Eggert <eggert@twinsun.com>
7003 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7004 inside '#ifndef __cplusplus'. Problem reported by
7005 Bob Friesenhahn.
7007 2003-07-06 Bill Clarke <llib@computer.org>
7009 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7010 'long', not 'int', for benefit of Sun's recent C++ compilers
7011 (trivial change). See:
7012 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7013 (This really should be 'intptr_t', not 'long', but that would
7014 take more work.)
7016 2003-06-25 Akim Demaille <akim@epita.fr>
7018 * lib/Makefile.am (autom4te.cfg): Make it read only.
7019 Depend on Makefile since it contains substitutions.
7020 From Paolo Bonzini.
7021 * lib/autom4te.in (args): Add local.at? for Autotest args.
7022 This change was made on autom4te.cfg which is generated.
7023 Reported by Raja R. Harinath.
7025 2003-06-25 Akim Demaille <akim@epita.fr>
7027 * doc/autoconf.texi (Header Portability): sys/mount.h.
7028 From Gareth McCaughan.
7030 2003-06-23 Akim Demaille <akim@epita.fr>
7032 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7033 not all of them. This fixes 1. the fact that when testing
7034 Autoconf there are many many config.log, 2. the incorrect use of
7035 top_srcdir to find config.log.
7036 Don't mix the detailed output of failed test with the summary of
7037 failures. Rather, append detailed log afterwards.
7039 2003-06-23 Akim Demaille <akim@epita.fr>
7041 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7042 always run: output config.log on $at_group_log.
7044 2003-06-23 Akim Demaille <akim@epita.fr>
7046 * tests/torture.at (#define header templates): Don't use quotes in
7047 C++ comments as it puzzles Emacs' sh font-lock-mode.
7049 2003-06-23 Akim Demaille <akim@epita.fr>
7051 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7052 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
7053 * tests/atspecific.m4: Rename as...
7054 * tests/local.at: This.
7055 * tests/suite.at: Move the globals into...
7056 * tests/local.at: here.
7057 * tests/Makefile.am: Adjust.
7058 * doc/autoconf.texi (testsuite Scripts): Adjust.
7060 2003-06-21 Kevin Ryde <user42@zip.com.au>
7062 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7063 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7064 ensuring we add -std1 for full-ANSI.
7066 * doc/autoconf.texi (hdrindex): New macro.
7067 Add index entries for portability of various standard header files.
7069 2003-06-20 Akim Demaille <akim@epita.fr>
7071 * configure.ac: Bump to 2.57b.
7073 2003-06-20 Akim Demaille <akim@epita.fr>
7075 Version 2.57a.
7077 2003-06-20 Akim Demaille <akim@epita.fr>
7079 * bin/autom4te.in: Don't rely on $HOME being defined.
7080 Reported by Marc Espie as PR/233.
7082 2003-06-20 Akim Demaille <akim@epita.fr>
7084 * lib/autotest/general.m4: Use at_times_file only if used.
7085 From Nicolas Joly.
7087 2003-06-20 Akim Demaille <akim@epita.fr>
7089 * config/config.guess, config/config.sub, config/elisp-comp,
7090 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7091 Update from masters.
7093 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7095 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7096 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7097 (TEST_SCRIPT): New diversion.
7098 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7099 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7100 (AT_INIT): Support for expected failures.
7102 2003-06-02 Akim Demaille <akim@epita.fr>
7104 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7105 changes.
7106 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7107 Autoconf nor Automake.
7108 (&contents): New, from Automake.
7109 PODify.
7111 2003-05-28 Paul Eggert <eggert@twinsun.com>
7113 * NEWS, doc/autoconf.texi (Particular Functions),
7114 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7115 is the inverse of localtime.
7117 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7119 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7120 (handle_exec_errors): New function. Work around $! being
7121 altered by WEXITSTATUS.
7122 (xqx, xsystem): Use handle_exec_errors.
7124 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7126 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7127 Do not call `_exit()', simply modify `$?'.
7128 (xsystem): Reset $! before running system, and check it afterward.
7129 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7130 63 for version mismatches.
7132 2003-05-23 Akim Demaille <akim@epita.fr>
7134 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7135 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7136 the middle of a line).
7137 * lib/m4sugar/m4sugar.m4: Likewise.
7138 Remove useless spaces in comments.
7140 2003-05-23 Akim Demaille <akim@epita.fr>
7142 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7143 exit 63, so that we (or Automake's "missing") can tell the
7144 difference with a plain failure.
7145 * doc/autoconf.texi (Notices): Adjust.
7147 2003-05-23 Akim Demaille <akim@epita.fr>
7149 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7150 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7151 White spaces cleanup.
7153 2003-05-22 Jim Meyering <jim@meyering.net>
7154 Paul Eggert <eggert@twinsun.com>
7156 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7157 Remove `#include <stdlib.h>' from the list; we should never
7158 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7159 resulting namespace pollution would cause other tests to fail.
7160 Configure scripts run with some older versions of g++ and HP's
7161 aCC would fail due to such an #include. Problems reported by
7162 Matthew Mueller in <http://bugs.debian.org/120704> and by
7163 Keith Bostic in
7164 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7165 In the test, use the test declaration before including <stdlib.h>,
7166 as that's closer to how it'll be used.
7168 2003-05-23 Akim Demaille <akim@epita.fr>
7170 * doc/autoconf.texi (Header Portability): ucred.h.
7171 From Ian Redfern.
7173 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7175 Overhaul Autotest's logging: generate separate log files
7176 in testsuite.dir/NNN/testsuite.log, and append them to
7177 testsuite.log instead of re-running the test verbosely.
7179 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7180 file descriptor, write 0 to at_status_file instead of setting
7181 at_status=0, initialize some new variables (at_status_file,
7182 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7183 to rerun the tests, instead append the at_group_log to the
7184 at_suite_log when a test fails.
7185 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7186 with the AS_MESSAGE_LOG_FD redirected to stdout.
7187 (AT_CLEANUP): save the output status in $at_status_file
7188 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7189 its original place.
7190 (AT_CHECK): since tests are run with a redirected stdout,
7191 and used to be re-run in verbose mode, turn some $at_verbose
7192 into echo, and don't redirect the output of testing stdout
7193 and stderr.
7195 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7196 the name of the debugging directory and information about
7197 its contents.
7199 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7201 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
7202 parameter.

7272 Reported by Sander Niemeijer.
7273 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
7274 * doc/autoconf.texi (Default Includes): Document

7314 and truncate.
7316 2003-05-06 Akim Demaille <akim@epita.fr>
7318 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7319 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7320 by aclocal.m4 is changed it might require the importing of another
7321 m4 extension file, i.e., aclocal must be run.
7323 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7324 (&parse_args): Use --force with aclocal if required and supported.
7325 (&autoreconf_current_directory): Use &run_aclocal.

7332 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7333 argument instead of a file name, so that the request file remains
7334 open during the whole autom4te run.
7335 ($icache_file): New.
7336 (&freeze): Lock the $icache_file.
7338 2003-04-29 Derek Price <derek@ximbiot.com>
7340 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7341 seperator with m4_append_uniq(). It doesn't work.
7342 (AT_CLEANUP): Add `;' to end of at_help_all.
7343 (AT_INIT): Allow --keywords to be specified more than once. When
7344 grepping $at_help_all for keywords, use the field and keyword
7345 seperators to ensure a complete keyword match. Alter at_prev handling
7346 to support the new --keywords behavior.
7348 2003-04-27 Karl Berry <karl@freefriends.org>
7350 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7351 align better with others. I also made some of the individual
7352 entries on one line, for brevity and to make it easier for me to
7353 sort my dir-example file in the Texinfo distribution :).
7355 2003-04-12 Jim Meyering <jim@meyering.net>

7420 header causes problems.
7422 2003-03-28 Akim Demaille <akim@epita.fr>
7424 * tests/torture.at (Configuring subdirectories): Require aclocal
7425 1.4, otherwise the test fails, as it does support configure.ac.
7426 This fixes the "test 40 failed" bug reports.
7428 2003-03-28 Akim Demaille <akim@epita.fr>
7430 * doc/autoconf.texi (C Compiler): `#line' portability.
7431 From Paul Eggert and Nelson H. F. Beebe.
7433 2003-03-27 Derek Price <derek@ximbiot.com>
7435 * lib/autotest/general.m4: Eliminate main loop and reorganize test
7436 layout in order to allow scripting around test groups.
7438 2003-03-27 Derek Price <derek@ximbiot.com>
7440 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
7441 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
7442 use new diversions in preparation for accepting new arguments and

7448 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
7449 obsolete AC_HELP_STRING.
7450 (AC_HELP_STRING): AU_DEFUN to...
7451 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
7452 * tests/m4sh.at (AS_HELP_STRING): New test.
7454 * tests/acgeneral.at: Regenerated.
7456 2003-03-26 Derek Price <derek@ximbiot.com>
7458 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
7459 sense. Verbosify the diversion definitions comment.
7461 2003-03-26 Derek Price <derek@ximbiot.com>
7463 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

7495 * doc/autoconf.texi (Limitations of Make): Remove the section
7496 about `$<' in inference rules, it was a bogus interpretation of
7497 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
7498 Tru64 make in the "target lookup" section.
7499 (Automake): Automake 1.5+ no longer requires special tools to be
7500 present on the developer's host.
7502 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
7504 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
7505 to a shell that can handle redirection or quoting correctly.
7506 Override SHELL with the shell detected by configure.
7507 Use of $^O suggested by Tim van Holder.
7508 * bin/autom4te.in (BEGIN): Likewise.
7509 * bin/autoreconf.in (BEGIN): Likewise.
7510 * bin/autoscan.in (BEGIN): Likewise.
7511 * bin/autoupdate.in (BEGIN): Likewise.
7512 * bin/ifnames.in (BEGIN): Likewise.
7514 * bin/ifnames.in: Add final newline to help and version messages.
7516 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
7517 to cope with DOS-style absolute paths, when constructing
7518 ${ac_make}.
7520 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
7521 When constructing paths with IFS=:, quote the path. If we're
7522 constructing a DOS-style absolute path, we don't want to split it
7523 on the colon.
7525 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
7526 in description.
7528 2003-02-25 Pavel Roskin <proski@gnu.org>

7535 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix typo in
7536 2002-09-01 patch by replacing "test -n" with "test -z".
7537 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
7538 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
7540 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
7541 to fix a mismatch between example and discussion.
7543 2003-02-24 Kevin Ryde <user42@zip.com.au>
7545 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
7546 format starting with "-".
7548 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7550 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
7551 is not portable inside Makefile.
7553 2003-02-20 Akim Demaille <akim@epita.fr>
7555 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7556 compiler says yeah, but preproc says nope, compiler is right.
7557 Conversely, prompt the reader to send a bug report to the
7558 maintainers of the package, not of Autoconf.
7560 2003-02-20 Klee Dienes <kdienes@apple.com>
7562 * bin/autoreconf.in (autoreconf_current_directory): Properly
7563 handle an empty aclocal.m4.

7568 $ac_prefix_program.
7569 From Larry Jones.
7571 2002-12-23 Paul Eggert <eggert@twinsun.com>
7573 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7574 innocuous variant befor including <limits.h> or <assert.h>. This
7575 works around a bug reported by Albert Chin: HP-UX 11i
7576 (and earlier versions) have a <limits.h> that declares
7577 gettimeofday and many other functions.
7579 2002-12-03 Paul Eggert <eggert@twinsun.com>
7581 Version 2.57.
7583 * NEWS, configure.ac: Update version.
7585 * doc/fdl.texi: Upgrade to FDL version 1.2.
7587 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7588 nontrivially in main's body, so that f's external declaration is
7589 not optimized away in AIX. This should fix the bug reported by
7590 Martin Frydl in
7591 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7593 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7594 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7595 defined, to support freestanding compilers. This should fix the
7596 bug reported by Momchil Velkov in
7597 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7599 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7600 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
7601 obsolete AC_CHECK_TYPE. The missing empty arg was reported
7602 by Simon Josefsson in

7605 * Makefile.maint (www-gnu): New macro.
7606 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
7607 the location has moved.
7609 2002-12-02 Martin Frydl <martin@systinet.com>
7611 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
7612 \(.*\) match is too long and there is something more to be checked.
7613 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
7615 2002-11-15 Akim Demaille <akim@epita.fr>
7617 Version 2.56.
7619 * config/install-sh: chmod +x.
7620 From Paul Eggert.
7621 * config/move-if-change: Indenting changes.
7622 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
7623 * configure.ac (AM_INIT_AUTOMAKE): here.
7624 Require 1.7.1.
7626 2002-11-14 Akim Demaille <akim@epita.fr>
7628 Version 2.55.
7630 * config/config.guess, config/config.sub, config/install-sh:
7631 Update from masters.
7633 2002-11-14 Akim Demaille <akim@epita.fr>
7635 * Makefile.maint: Sync with Bison, i.e.:
7636 (po-check): Scan .l and .y files instead of the
7637 .c and the .h files that they generate. This fixes the bug
7638 reported by Tim Van Holder in:
7639 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7640 Look for N_ as well as for _. Try to avoid matching #define for
7641 N_ and _.
7642 From Paul Eggert.
7644 2002-11-14 Akim Demaille <akim@epita.fr>
7646 * doc/autoconf.texi (C Compiler): Compiling several files at once.
7647 From Paul Eggert and Albert Chin-A-Young.
7649 2002-11-14 Akim Demaille <akim@epita.fr>
7651 * doc/autoconf.texi (C Compiler): Solitary backslashes.
7652 From Paul Eggert and Albert Chin-A-Young.
7654 2002-11-14 Kevin Ryde <user42@zip.com.au>
7656 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
7657 than assigning in main, to avoid HP cc +O3 optimizing it away.
7659 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
7661 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
7662 option. Process --recheck after parsing all options. Pass -q
7663 option to configure on --recheck.
7664 (AC_OUTPUT): Pass -q from configure to config.status.
7665 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
7666 arguments to record.
7667 * doc/autoconf.texi (config.status Invocation): Document
7668 config.status -q option.
7670 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
7672 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
7673 Makefile.in if Makefile.am exists.
7674 (output): Strip `.am' from Makefiles. Don't
7675 output AC_CONFIG_FILES if no Makefiles were found.
7677 2002-11-07 Akim Demaille <akim@epita.fr>
7679 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
7680 (local_updates): New.
7681 * Makefile.maint: Update, from CVS Bison.
7682 (local_updates): New.
7684 2002-11-06 Akim Demaille <akim@epita.fr>
7686 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
7687 declaration in extern "C" too.
7688 Reported by Roberto Bagnara.
7690 2002-11-06 Akim Demaille <akim@epita.fr>
7692 * tests/torture.at (Configuring subdirectories): Don't use grep
7693 -w.
7694 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
7695 Reported by Ezra Peisach.
7697 2002-11-05 Akim Demaille <akim@epita.fr>
7699 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7700 Remove.
7701 We _have_ to stop using the old compatibility scheme that tried to
7702 avoid useless backslashes because Libtool 1.4.3 contains a
7703 AC_DEFINE([error_t], [int],
7704 [Define to a type to use for \`error_t' if it is not
7705 otherwise available.])
7706 We _have_ to quote the single quote and backslashes with \. The
7707 old compatibility scheme saw that ` was backslashed, and therefore
7708 did not quote the single quote. Hence before this patch, Autoconf
7709 was not compatible with Libtool.
7711 2002-11-04 Paul Eggert <eggert@twinsun.com>
7713 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
7714 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
7715 LC_NAME, LC_PAPER, LC_TELEPHONE.
7716 * doc/autoconf.texi (Special Shell Variables): Mention those vars.
7718 2002-11-04 Akim Demaille <akim@epita.fr>
7720 Version 2.54c.
7722 * Makefile.maint (update, cvs-update, po-update, do-po-update):
7723 New.
7724 * config/texinfo.tex: Update.
7726 2002-11-03 Akim Demaille <akim@epita.fr>
7728 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
7729 from...
7730 (&autoreconf): here.
7731 ($help, $make, &parse_args, &autoreconf_current_directory):
7732 Support -m/--make.
7733 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7735 2002-10-31 Bruno Haible <bruno@clisp.org>
7737 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.
7738 Change name of cache variable to ac_cv_func_malloc_0_nonnull.
7739 (AC_FUNC_MALLOC): Change description of HAVE_MALLOC macro.
7740 (_AC_FUNC_REALLOC_IF): Change message. Change name of cache variable
7741 to ac_cv_func_realloc_0_nonnull.
7742 (AC_FUNC_REALLOC): Change description of HAVE_REALLOC macro.
7744 2002-10-31 Akim Demaille <akim@epita.fr>
7746 The test suite was no longer checking for trailing envvars and files.
7748 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
7749 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
7751 2002-10-31 Akim Demaille <akim@epita.fr>
7753 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
7754 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
7755 Make variable, not a shell variable.
7756 Suggested by Bruno Haible.
7758 2002-10-31 Akim Demaille <akim@epita.fr>
7760 * bin/autom4te.in (load_configuration): Reject #args out of any
7761 language.
7763 2002-10-31 Akim Demaille <akim@epita.fr>
7765 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
7766 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
7767 (_AC_RUN_IFELSE): Use it.
7768 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
7769 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.

8041 2002-10-22 Akim Demaille <akim@epita.fr>
8043 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

8047 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
8048 strings.
8050 2002-10-22 Akim Demaille <akim@epita.fr>
8052 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

8099 longer required can still cause errors.
8100 Reported by Alexandre Duret-Lutz.
8102 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8103 to frozen files in @ARGV, as @ARGV must remain being a list of

8105 (&files_to_options): New function.
8106 (&freeze): Use &error.
8107 (&up_to_date): If a file that was included according to the cache
8108 is no longer there, then the output is out dated.

8110 --force is given.
8111 * tests/tools.at (autom4te cache): New.
8113 2002-10-16 Akim Demaille <akim@epita.fr>

8120 that error messages can be easily located, and use GNU Make
8121 format, so that Emacs' compile mode understands us.
8122 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8123 if some file was changed instead of `print'.
8124 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

8158 file name to enable parallel executions.
8159 From Sam Varshavchik.
8161 2002-10-08 Akim Demaille <akim@epita.fr>
8163 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8164 aclocal invocation, as Gettext macros might not be visible to
8165 aclocal.
8166 Instead of blindly running autopoint, scan configure.ac (not the
8167 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8168 Reported by Paul D. Smith.
8170 2002-10-08 Paul Eggert <eggert@twinsun.com>
8172 Work around problems found when POSIXLY_CORRECT=1 is set.
8173 None of this seems to have anything to do with POSIX, really,

8175 * bin/autom4te.in (parse_args): Configure GetOpt with
8176 "permute", too.
8177 * doc/autoconf.texi (Invoking autom4te):

8200 * tests/torture.at (Configuring subdirectories): Be robust to
8201 users who use config.site to require for a cache: in this case,
8202 the two last configure runs, using two different sets of
8203 arguments, trigger a legitimate error.
8205 2002-09-28 Akim Demaille <akim@epita.fr>

8221 (tm_zone): Move their rules to...
8222 * lib/autoconf/types.m4: here, using AN_ macros.
8223 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8224 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8225 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
8226 * lib/autoconf/programs.m4: here.

8240 tests/autom4te itself.
8241 * lib/autoscan/Makefile.am: Include freeze.mk.
8242 (autoscan.list): New target --this file is no longer a source.
8243 (autoscan.pre): New file.

8248 Adjust all uses.
8249 (&init_tables): When --debug, report the list of rules to ease
8250 tracking changes in autoscan.list.
8251 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8253 2002-09-28 Akim Demaille <akim@epita.fr>

8263 * lib/autoscan/functions, lib/autoscan/headers,
8264 * lib/autoscan/identifiers, lib/autoscan/makevars,
8265 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8266 `functions' line is now prefixed with `function:'.
8267 * bin/autoscan.in (&init_tables): Adjust.
8269 2002-09-28 Akim Demaille <akim@epita.fr>
8271 From now on, autoscan files must always map a macro name to a
8272 word: there is no `default' macro for autoscan.
8274 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8275 all.
8276 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8277 explicit.
8279 2002-09-28 Akim Demaille <akim@epita.fr>
8281 * bin/autoscan.in (%c_keywords): Remove.
8282 (&used): Keep only track of the words we might be interested in.
8283 (&output_kind): It is no longer needed to look for non active
8284 checks.
8286 2002-09-27 Akim Demaille <akim@epita.fr>
8288 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

8293 2002-09-27 Akim Demaille <akim@epita.fr>
8295 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
8296 from /tmp.
8297 Thanks to Bill Moseley and Paul Eggert.
8298 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8299 the tmpdir must be created.
8300 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8301 dir be in the build tree, instead of $TMPDIR.
8303 2002-09-27 Akim Demaille <akim@epita.fr>
8305 * bin/autoscan.in: Improve the comments.
8306 (&parse_args): Drop obsolete undocumented options.
8307 (&output_kind): Output warnings.
8308 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

8314 Reported by Ralf Corsepius.
8315 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8317 2002-09-26 Akim Demaille <akim@epita.fr>
8319 Single suffix rules and seperated dependencies are not portable.
8321 * doc/autoconf.texi (Installation Directory Variables): Update.
8322 (Limitations of Make): Some about `Single Suffix Rules and
8323 Separated Dependencies'.
8324 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8325 (ifnames, autoscan, autom4te): Un-factor into several rules.
8327 2002-09-25 Paul Eggert <eggert@twinsun.com>
8329 * BUGS (Interoperability bugs): New section. Mention libtool
8330 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8332 2002-09-24 Paul Eggert <eggert@twinsun.com>
8334 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8335 make handles suffix-rules differently from GNU make.
8337 * bin/Makefile.am (SUFFIXES, .in): Remove.
8338 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8339 Move the body of the old .in rule here.
8341 2002-09-16 Akim Demaille <akim@epita.fr>
8343 i960 compilers create `b.out' files by default.
8344 Reported by Ralf Corsepius.
8346 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8347 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8349 2002-09-13 Paul Eggert <eggert@twinsun.com>
8351 * doc/autoconf.texi (Particular Headers): Remove obsolete
8352 reference to `struct timezone' in the description of
8353 AC_HEADER_TIME.
8355 2002-09-13 Akim Demaille <akim@epita.fr>
8357 Version 2.54.
8359 * config/config.sub, config/config.guess: Update.
8360 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8361 * Makefile.am: Adjust.
8363 2002-09-13 Akim Demaille <akim@epita.fr>
8365 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8366 reading config.log when the compiler is rejected.
8367 Suggested by Guido Draheim.
8369 2002-09-13 Akim Demaille <akim@epita.fr>
8371 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8372 (chdir_init) might hang when stat'ing mounted directories.
8373 Reported by Vance Shipley.
8375 2002-09-12 Akim Demaille <akim@epita.fr>
8377 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8378 the lists.
8380 2002-09-12 Akim Demaille <akim@epita.fr>
8382 * doc/autoconf.texi (Defining Symbols): Present two different
8383 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8384 difference between 1 argument calls, and 2-3 argument calls.
8386 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8388 * doc/autoconf.texi: Review grammar and punctuation.
8390 2002-09-11 Paul Eggert <eggert@twinsun.com>
8392 * doc/autoconf.texi: Fix minor formatting, spelling, and
8393 grammatical typos.
8394 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8395 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8396 is obsolescent.
8398 2002-09-11 Akim Demaille <akim@epita.fr>
8400 * doc/autoconf.texi (Questions): Rename as...
8401 (FAQ): this.
8402 (Defining Directories): New.
8404 2002-09-09 Akim Demaille <akim@epita.fr>
8406 * doc/autoconf.texi (Making testsuite Scripts): Update.
8407 Suggested by Nishio Futoshi.
8409 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8411 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8412 plain `@' is wanted.
8414 2002-09-09 Akim Demaille <akim@epita.fr>
8416 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8417 `duplicates', since the algorithm was too naive and could keep
8418 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8419 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8420 Reported by Ralf Corsepius.
8421 * tests/torture.at (Configuring subdirectories): Exercise these
8422 cases.
8424 2002-09-09 Akim Demaille <akim@epita.fr>
8426 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8427 looking for a replacement file.
8428 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8429 directory is relative.
8430 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8431 directory definition.
8432 Reported by Andreas Schwab and Jim Meyering.
8434 2002-09-06 Akim Demaille <akim@epita.fr>
8436 * doc/autoconf.texi (Setting Output Variables): Clarify what
8437 precious variables are.
8438 Suggested by Pontus Skoeld.
8440 2002-09-05 Akim Demaille <akim@epita.fr>
8442 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8443 (ifnames, autoscan, autom4te): Since we don't only depend on
8444 configure.ac variables (such as VERSION etc.), but also on prefix
8445 and so forth, depend on Makefile, not configure.ac.
8446 Reported by Alexandre Duret-Lutz.
8447 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8449 2002-09-05 Kevin Ryde <user42@zip.com.au>
8451 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8452 doesn't seem to be confined to ia64, just say "some versions".
8454 2002-09-04 Akim Demaille <akim@epita.fr>
8456 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8457 Automake 1.6c.
8458 * Makefile.am (maintainer-clean-local): Remove.
8459 (MAINTAINERCLEANFILES): Remove COPYING.
8461 2002-09-03 Paul Eggert <eggert@twinsun.com>
8463 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8464 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8465 Brinkmann.
8467 2002-09-03 Akim Demaille <akim@epita.fr>
8469 * configure.ac: Bump to 2.53d.
8470 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8471 as of today, on Automake's team suggestion.
8473 2002-09-03 Akim Demaille <akim@epita.fr>
8475 Version 2.53c.
8477 2002-09-02 Akim Demaille <akim@epita.fr>
8479 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8480 SITE_MACRO_DIR.
8481 * configure.ac: Disable SITE_MACRO_DIR.
8483 2002-09-02 Jim Meyering <meyering@lucent.com>
8485 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8486 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8487 Also, tweak grammar: s/make sure to/be sure to/.
8489 2002-09-02 Paul Eggert <eggert@twinsun.com>
8491 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8492 directory names are generally preferable to physical names.
8494 2002-09-02 Akim Demaille <akim@epita.fr>
8496 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8497 Reported by Raja R. Harinath.
8498 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8499 * bin/autoupdate.in: Use error instead of die.
8501 2002-09-01 Paul Eggert <eggert@twinsun.com>
8503 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8504 ordinary shell concatenation rather than echo+tr+sed command that
8505 runs afoul of a long-line-related sed bug in Solaris 8.
8507 * bin/autoheader.in (parse_args): --warning -> --warnings.
8509 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8510 stdout, as traditional "ls" does.
8511 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8512 _AC_COMPILER_EXEEXT_O): Likewise.
8513 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8515 * bin/autoconf.as: Add --prepend-include option. This patch was
8516 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8517 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8519 * bin/autoconf.in, configure: Regenerate.
8521 * doc/autoconf.texi (Special Shell Variables): Mention
8522 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8524 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8525 MAILPATH and set PS1, PS2, PS4 to default values, to work
8526 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8527 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8528 the Autoconf documentation specifies; fall back to "unset" only if
8529 this fails. Use a shell for-loop for this rather than an m4 loop,
8530 to shorten the output script.
8532 2002-08-30 Paul Eggert <eggert@twinsun.com>
8534 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8535 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8536 for the CDPATH problem. Document PWD.
8537 (Limitations of Builtins): Document the problem that "cd $foo" and
8538 "ls $foo" may refer to different directories in shells conforming
8539 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8540 example, since the old example is now out of date.
8542 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8543 FOO" and "ls FOO" talk about different directories; this catches
8544 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8545 spaghetti.
8547 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8548 of rolling our own unset.
8549 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8550 in practice we needn't worry about CDPATH if unset doesn't work.
8552 * Makefile.in, aclocal.m4, bin/Makefile.in,
8553 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8554 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8555 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8556 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8557 tests/Makefile.in: Regenerate with Automake 1.6.3.
8559 * config/config.guess, config/config.sub, config/mkinstalldirs:
8560 Update.
8562 * configure: Regenerate with self.
8564 2002-08-30 Kevin Ryde <user42@zip.com.au>
8566 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8567 default output.
8569 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8571 * bin/autom4te.in (Request::load): Correctly test for "do" read
8572 failure.
8574 2002-08-29 Akim Demaille <akim@epita.fr>
8576 * lib/Autom4te/General.pm (&xqx): New.
8577 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8578 hand, which is not portable.
8579 (&error): New.
8580 * bin/autom4te.in: Use them.
8581 Use &error instead of die.
8582 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8583 Adjust.
8585 2002-08-17 Paul Eggert <eggert@twinsun.com>
8587 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8588 default list of compilers to try, since it was long ago superseded
8589 by the ksh fc builtin. Suggested by Steven G. Johnson.
8591 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8593 * doc/autoconf.texi (Invoking autom4te): End the option table,
8594 fixing a bug introduced by the previous patch.
8595 (Limitations of Make): Add a 'target lookup' subentry in the
8596 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8598 2002-07-29 Mark D. Roth <roth@feep.net>
8600 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8601 options and use $AUTOM4TE_PATH.
8602 * doc/autoconf.texi: Remove documentation of autom4te
8603 --include-envvar and --site-macro-subdir options and document
8604 use of $AUTOM4TE_PATH.
8605 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8606 arguments from each language section.
8608 2002-07-29 Paul Eggert <eggert@twinsun.com>
8610 * doc/install.texi: Include copyright symbol in copyright notice.
8612 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8613 Replace with:
8614 (AM_MAKEINFOFLAGS): New macro.
8615 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8616 * Makefile.am (INSTALL): Use the new macros.
8617 Use -o rather than --output, since "missing" does not grok --output.
8619 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8621 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8622 comments do not always work. Never trust the exit status of
8623 `make -k'.
8625 2002-07-24 Kevin Ryde <user42@zip.com.au>
8627 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8628 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8630 2002-07-23 Paul Eggert <eggert@twinsun.com>
8632 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8633 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8634 apparently treats PATH="nonexistent" as if it contained ".".
8635 Bug reported by Stefan `Sec' Zehl.
8637 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8639 * doc/autoconf.texi (Limitations of Make): Mention the special
8640 handling of the obj/ directory by BSD make.
8642 2002-07-20 Kevin Ryde <user42@zip.com.au>
8644 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
8645 backslashes.
8647 2002-07-19 Akim Demaille <akim@epita.fr>
8649 * doc/autoconf.texi (Function Portability): `exit'.
8650 (Programming in M4sh): Ethymology of M4sh.
8652 2002-07-19 Akim Demaille <akim@epita.fr>
8654 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
8656 2002-07-18 Akim Demaille <akim@epita.fr>
8658 Version 2.53b.
8660 2002-07-18 Akim Demaille <akim@epita.fr>
8662 * config/config.guess, config/config.sub: Update.
8664 2002-07-18 Akim Demaille <akim@epita.fr>
8666 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
8667 Automake's parts.
8669 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
8670 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
8671 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
8673 2002-07-18 Akim Demaille <akim@epita.fr>,
8674 Alexandre Duret-Lutz <duret_g@epita.fr>
8676 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
8677 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

8682 description of the tarname default.

8686 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
8687 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
8688 latter was not run.
8690 2002-07-17 Akim Demaille <akim@epita.fr>
8692 * lib/Autom4te/General.pm (find_file): Browse the directories in
8693 the order they are given.
8695 2002-07-17 Akim Demaille <akim@epita.fr>
8697 * tests/wrapsh.as, tests/wrappl.as: Merge into...
8698 * tests/wrapper.as: this.
8699 * tests/Makefile.am, configure.ac: Adjust.
8701 2002-07-17 Mark D. Roth <roth@feep.net>
8703 * configure.ac: Add --enable-site-macro-dir option.

8705 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
8706 --site-macro-subdir options.
8707 * bin/autoconf.in: Add --prepend-include option.
8708 * bin/autoheader.in: Add --prepend-include option.

8713 macro directory, remove note that include path directories are
8714 used in reverse order, and document --prepend-include option.
8715 * lib/autom4te.in: Use --prepend-include instead of --include.
8716 * tests/wrapsh.in: Use --prepend-include instead of --include.
8718 2002-07-17 Akim Demaille <akim@epita.fr>
8720 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): `_' is allowed in
8721 tarnames.
8722 * doc/autoconf.texi (Initializing configure): Adjust.
8724 2002-07-17 Akim Demaille <akim@epita.fr>
8726 * lib/autoconf/functions.m4 (AC_FUNC_REALLOC, _AC_FUNC_REALLOC)
8727 (_AC_FUNC_MALLOC): New.

8754 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
8756 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,

8758 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
8759 so that Emacs setups GNU style for perl-mode and cperl-mode.
8761 2002-06-27 Paul Eggert <eggert@twinsun.com>
8763 * config/install-sh: Quote $src. Prefer || to test's -o option,
8764 as per "Limitations of Builtins".
8765 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
8766 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
8768 * tests/mktests.sh: Use grep instead of fgrep, as per
8769 "Limitations of Builtins".

8796 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
8798 * bin/autom4te.in ($cache): Don't define using `$me', the name
8799 of the cache should not depend on the name under which autom4te
8800 was installed.
8802 2002-06-07 Akim Demaille <akim@epita.fr>
8804 * tests/tools.at (autoconf: forbidden tokens, basic)

8806 words in autom4te.in.
8808 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
8810 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
8811 _AC_LANG_PROGRAM_C_F77_HOOKS.
8813 2002-06-07 Akim Demaille <akim@epita.fr>
8815 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
8816 rename as...
8817 (AC_REPLACE_FNMATCH): this.
8818 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
8819 AC_FUNC_FNMATCH_GNU.
8821 2002-06-07 Akim Demaille <akim@epita.fr>
8823 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
8824 Rosetta Stone for Unix.
8826 2002-06-07 Akim Demaille <akim@epita.fr>
8828 * bin/autom4te.in (warn_forbidden): When rejecting a token,
8829 suggest m4_pattern_allow.
8830 Suggested by Adam J. Richter.
8832 2002-06-07 Akim Demaille <akim@epita.fr>
8834 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
8835 ac_config_libobj_dir.
8836 (AC_CONFIG_LIBOBJ_DIR): New.
8837 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
8838 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
8839 Use ac_config_libobj_dir to find the replacement files.
8840 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
8841 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)

8844 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
8845 * tests/mktests.sh (ac_exclude_list): Don't check

8848 2002-06-06 Paul Eggert <eggert@twinsun.com>
8850 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
8851 if ln doesn't work.
8852 * NEWS: Likewise.
8853 * doc/autoconf.texi (Configuration Links): Likewise.
8854 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
8856 2002-06-05 Paul Eggert <eggert@twinsun.com>
8858 * config/config.guess, config/config.sub, config/texinfo.tex:

8891 version of Autoconf that is discussed.
8893 2002-05-22 Paul Eggert <eggert@twinsun.com>
8895 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
8896 from the default list of compilers to try. Suggested by
8897 Kate Hedstrom.
8898 * NEWS: Document the above.
8899 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
8901 2002-05-17 Paul Eggert <eggert@twinsun.com>
8903 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
8904 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
8905 This improves on an earlier suggestion by H. Peter Anvin.
8907 2002-05-16 Paul Eggert <eggert@twinsun.com>
8909 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
8910 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
8911 Both macros now accept an optional source-dir arg.
8912 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
8914 * NEWS: Document this.
8915 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
8917 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
8918 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
8919 not for GNU extensions; this undoes part of the 2000-11-03 change,
8920 reverting to 2.13-compatible behavior.
8921 Add new optional argument DIR.
8922 (AC_FUNC_FNMATCH_GNU): New macro.
8924 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
8926 2002-05-08 Paul Eggert <eggert@twinsun.com>
8928 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
8929 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
8930 and it causes a 'test' syntax error if it fails.
8931 Bug reported by Stephen Gildea.
8933 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8934 If prototypes are supported, use them to check this at compile-time,
8935 instead of trying to check it at run-time. If we must do a run-time
8936 check, assume that setvbuf is standard when cross-compiling, as
8937 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8938 Bug reported by Paul D. Smith.
8940 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8941 argument specifying location of getloadavg.c. This removes a
8942 FIXME. This idea was taken from Jim Meyering's implementation in
8943 textutils.
8944 * doc/autoconf.texi (Particular Functions): Document this.
8945 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8946 that's what the code does; this fixes a bug reported by
8947 Paul D. Smith.
8949 2002-05-03 Akim Demaille <akim@epita.fr>
8951 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8952 autopoint instead of gettextize.
8953 ($uses_alocal): Rename as...
8954 ($uses_aclocal): this.
8955 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8956 Suggested by Bruno Haible.
8958 2002-05-03 Akim Demaille <akim@epita.fr>
8960 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
8962 2002-04-29 Paul Eggert <eggert@twinsun.com>
8964 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
8965 files to be 1 second older; just set them to be the same time.
8966 Also, sleep 1 second after the first aclocal, to work around
8967 problems with sub-second time stamps on the input files.
8969 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
8971 * doc/autoconf.texi: Mention "set -e -x" lossage
8972 under node "Limitations of Builtins".
8974 2002-04-29 Akim Demaille <akim@epita.fr>
8976 * doc/install.texi: Better wording for setting variables when
8977 running configure.
8978 From Christian Cornelssen.
8980 2002-04-29 Akim Demaille <akim@epita.fr>
8982 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
8983 of lack of $LINENO support, then the test will compare the $LINENO
8984 in testsuite vs. the lineno in the test file. This is wrong, of
8985 course.
8986 Be sure to protect it.
8987 Reported by Patrick Welche.
8989 2002-04-25 Akim Demaille <akim@epita.fr>
8991 * doc/autoconf.texi (Obsolete Macros): Typo.
8992 Reported by Vladimir Volovich.
8994 2002-04-25 Akim Demaille <akim@epita.fr>
8996 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
8997 than some of the input files, hence, on the second run of aclocal,
8998 if some of its input are younger, make them older.
8999 Suggested by Paul Eggert.
9001 2002-04-25 Akim Demaille <akim@epita.fr>
9003 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9004 Thanks to Paul Eggert.
9006 2002-04-25 Akim Demaille <akim@epita.fr>
9008 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9009 and ac_subst_vars be sh variables containing the list of
9010 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9011 DEFAULT diversion.
9012 (_AC_INIT_PREPARE): Use them to log them.
9013 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9014 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9015 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9016 _AC_SUBST_FILES and _AC_SUBST_VARS.
9017 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9019 2002-04-24 Akim Demaille <akim@epita.fr>
9021 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9022 autoheader, so that automake does not complain about a missing
9023 config.h.in that was to be created.
9025 2002-04-23 Akim Demaille <akim@epita.fr>
9027 * bin/autoheader.in (parse_args): --warning takes an argument.
9028 Fixes PR/220.
9030 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
9032 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

9077 Minor spelling and grammar fixes.
9079 * doc/autoconf.texi: Follow the outline suggested in the GNU
9080 Sample Texts sections of the Texinfo 4.2 manual. Most
9081 importantly, this makes sure that the copyright notices appear in
9082 all output formats. You probably need Texinfo 4.2 to generate
9083 the manual now.
9085 Fix some bugs when using "$@" when there might be zero positional

9138 * lib/autotest/general.m4 (AT_INIT): Likewise.
9139 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

9188 Don't use the KILL diversion, as it kills spurious output, which
9189 results in failures being hidden.

9192 after the second argument.

9240 2002-03-27 Paul Eggert <eggert@twinsun.com>
9242 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9243 (AS_SHELL_SANITIZE): Invoke it.
9244 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9246 2002-03-26 Akim Demaille <akim@epita.fr>
9248 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9250 2002-03-26 Akim Demaille <akim@epita.fr>
9252 * doc/autoconf.texi (Introduction): The GNATS base moved.
9254 2002-03-25 Paul Eggert <eggert@twinsun.com>
9256 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9257 as POSIX requires, as it doesn't work with Zsh.
9258 * doc/autoconf.texi (Assignments): Document the problem.
9260 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9262 * doc/autoconf.texi (Limitations of Make): Mention more issue
9263 about VPATH, overriding of macros in sub-makes, and handling of
9264 SHELL.
9266 2002-03-21 Paul Eggert <eggert@twinsun.com>
9268 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9269 problem with here-document buffer boundaries.
9271 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9272 when reinvoking the shell, to work around problems with installers
9273 who put strange things like "cd" commands in their environments.
9275 2002-03-19 Akim Demaille <akim@epita.fr>
9277 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9278 From Aaron Ucko.
9280 2002-03-19 Akim Demaille <akim@epita.fr>
9282 * bin/autoscan.in (scan_file): Specify the location in `&used'
9283 invocations.
9284 From Nicolas Joly.
9286 2002-03-19 Akim Demaille <akim@epita.fr>
9288 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9289 From Nishio Futoshi.
9291 2002-03-19 Akim Demaille <akim@epita.fr>
9293 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9295 2002-03-18 Paul Eggert <eggert@twinsun.com>
9297 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9298 (Limitations of Usual Tools): Add mkdir section.
9300 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9301 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9302 back on AS_DIRNAME to compute prefixes otherwise; this is
9303 roughly what mkinstalldirs does. That way, we need not have
9304 our own filename disassembler. The old disassembler did not
9305 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9307 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9308 Create at_test_all by a series of assignments,
9309 not by a single assignment of a long string. The latter causes ksh
9310 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9311 presumably because of a buffer overrun.
9313 2002-03-14 Paul Eggert <eggert@twinsun.com>
9315 * lib/autotest/general.m4 (at_times_skip):
9316 Renamed from at_times. Now a boolean.
9317 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9318 says 'times: not found'.
9320 2002-03-14 Akim Demaille <akim@epita.fr>
9322 * bin/autoreconf.in (&study_gettextize): New.
9323 (&autoreconf): Handle newest gettextize.
9324 Rerun aclocal if needed.
9325 Suggested by Andreas Schwab.
9327 2002-03-13 Akim Demaille <akim@epita.fr>
9329 * doc/autoconf.texi (Special Shell Variables): More about IFS.
9331 2002-03-13 Akim Demaille <akim@epita.fr>
9333 * doc/autoconf.texi (Header Portability): New.
9334 Add information about stdint.h and inttypes.h from Paul Eggert.
9336 2002-03-13 Akim Demaille <akim@epita.fr>
9338 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9339 -p'.
9340 From Bob Proulx.
9342 2002-03-12 Akim Demaille <akim@epita.fr>
9344 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9345 m4_require.
9347 2002-03-11 Andreas Schwab <schwab@suse.de>
9349 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9350 does not do it if --with-lispdir is given.
9352 2002-03-08 Akim Demaille <akim@epita.fr>
9354 Version 2.53.
9356 2002-03-08 Akim Demaille <akim@epita.fr>
9358 * doc/autoconf.texi (Subdirectories): Clarify that the
9359 subdirectory should exist.
9361 2002-03-08 Akim Demaille <akim@epita.fr>
9363 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9365 2002-03-08 Akim Demaille <akim@epita.fr>
9367 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9368 aliases the actual variables, and modifications of the former
9369 affect the latter.
9371 2002-03-08 Akim Demaille <akim@epita.fr>
9373 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9374 because of C-c: have m4 output in tmp files, then mv them.
9376 2002-03-08 Akim Demaille <akim@epita.fr>
9378 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9379 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
9380 * bin/ifnames.in: Copyright update.
9382 2002-03-08 Akim Demaille <akim@epita.fr>
9384 * doc/autoconf.texi (Invoking autom4te): New.
9386 2002-03-05 Akim Demaille <akim@epita.fr>
9388 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9389 Kevin Ryde.
9391 2002-03-05 Akim Demaille <akim@epita.fr>
9393 Version 2.52i.
9395 2002-03-04 Akim Demaille <akim@epita.fr>
9397 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9398 * lib/autoconf/general.m4 (AC_INIT): More informative error
9399 message for LIBOBJ.
9401 2002-03-04 Akim Demaille <akim@epita.fr>
9403 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9404 parallel builds.
9406 2002-03-04 Akim Demaille <akim@epita.fr>
9408 * doc/autoconf.texi (Transforming Names): Equality between target
9409 and host is irrelevant.
9410 (Specifying Names, Canonicalizing): Remove all references to the
9411 backward compatibility hooks. Rather, collect them all into...
9412 (Hosts and Cross-Compilation): this new section.
9413 * doc/install.texi (System Type): Ditto.
9414 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9415 that `--host' implies cross-compilation.
9417 2002-03-04 Akim Demaille <akim@epita.fr>
9419 * doc/autoconf.texi (Evaluation Macros): New.
9420 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9421 useless.
9422 (_m4_foreach): Define the variant with immediate evaluation so
9423 that it contains exactly the items, not an expression which
9424 evaluation is the current item.
9425 (m4_re_string, m4_re_word): Don't over quote them.
9427 2002-03-04 Akim Demaille <akim@epita.fr>
9429 Instead of having stacking `shift's evaluated at the end, let
9430 `foreach' loops immediately evaluate them.
9432 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9433 $*. This is the n-th time I change my mind, but hopefully this is
9434 the last...
9435 (m4_lquote): New.
9436 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9437 efficient.
9438 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9439 it was only a hack for m4_text_wrap.
9440 (m4_car2): Remove, replaced by...
9441 (m4_cdr): New.
9442 (_m4_foreach): Adjust.
9443 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9444 m4_bpatsubst for clarification.
9446 2002-03-04 Akim Demaille <akim@epita.fr>
9448 * doc/autoconf.texi (Changequote is Evil): New.
9450 2002-03-03 Kevin Ryde <user42@zip.com.au>
9452 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
9453 on old systems like SunOS.
9455 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
9457 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,

9472 2002-02-25 Akim Demaille <akim@epita.fr>
9474 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
9475 From Akinori Musha.
9477 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
9479 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
9480 translate \r\n to \n.
9482 2002-02-07 Akim Demaille <akim@epita.fr>
9484 Version 2.52h.
9486 2002-02-07 Akim Demaille <akim@epita.fr>
9488 Fix Autoconf PR/209.
9489 Also reported by Frank Denis.
9491 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
9493 2002-02-07 Akim Demaille <akim@epita.fr>
9495 Fix Autoconf PR/207:
9496 AC_PREFIX_PROGRAM fails with dashed program names
9498 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9499 variable when looking for the prefix program.
9500 Now it also works for shell variables.
9502 2002-02-07 Akim Demaille <akim@epita.fr>
9504 * doc/autoconf.texi (Limitations of Builtins): More about
9505 case/esac.
9507 2002-02-06 Akim Demaille <akim@epita.fr>
9509 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
9510 case/esac, some shells don't support it.
9511 Reported by Zack Weinberg.
9512 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
9514 2002-02-06 Akim Demaille <akim@epita.fr>
9516 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9517 sure not to introduce newlines in at_groups.
9518 * lib/autotest/Makefile.am (autotest.m4f): Typo.
9520 2002-02-06 Akim Demaille <akim@epita.fr>
9522 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9523 is not available.
9525 2002-02-05 Paul Eggert <eggert@twinsun.com>
9527 * doc/autoconf.texi (Specific Compiler Characteristics):
9528 Describe HP-UX cc bug workaround more accurately.
9529 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
9530 not unsigned long.
9531 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9532 cross-compilers, too. This undoes some of the most recent change
9533 to this file.
9535 2002-02-05 Akim Demaille <akim@epita.fr>
9537 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9538 to make sure they are up to date when `check' is run.

9549 2002-02-05 Akim Demaille <akim@epita.fr>
9551 Implement `autom4te --freeze'.
9553 * bin/autom4te.in (&freeze): New.
9554 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9555 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9557 2002-02-05 Akim Demaille <akim@epita.fr>
9559 * bin/autom4te.in (&parse_args): Implement `frozen files are
9560 optional are the sum of the previous files on the command line'.
9561 Also, pass `--reload-state=' on them, so...
9562 (handle_m4): don't.
9563 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9564 (M4sh): Rely on M4sugar.
9565 (Autotest, M4sh, M4sugar): Use frozen files.
9567 2002-01-31 Akim Demaille <akim@epita.fr>
9569 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
9570 * doc/autoconf.texi (Initializing configure): Adjust.
9572 2002-01-30 Akim Demaille <akim@epita.fr>
9574 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9575 alphanumeric to `-' instead of `_'.
9577 2002-01-30 Akim Demaille <akim@epita.fr>
9579 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9580 for plain code, the other for cross-compilation code. The latter
9581 is now run with GCC only.
9582 * doc/autoconf.texi (Compilers and Preprocessors): New.
9584 2002-01-30 Akim Demaille <akim@epita.fr>
9586 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
9587 values.
9588 * doc/autoconf.texi (Initializing configure): Explain how to
9589 change AC_INIT default values.
9591 2002-01-29 Akim Demaille <akim@epita.fr>
9593 * tests/torture.at (Configuring subdirectories): Use configure.in,
9594 so that aclocal 1.4 works.
9595 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9597 2002-01-28 Akim Demaille <akim@epita.fr>
9599 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9600 needs an argument.
9602 2002-01-28 Akim Demaille <akim@epita.fr>
9604 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9605 AUTOTEST_PATH *after* it was set.
9606 Don't put `.' in the PATH: the user should be precise and `./' if
9607 needed. In addition, given that the test suite does some `cd', if
9608 `.' is in the path, the `tested programs' sections will report
9609 programs found in the test suite's directory, while during the
9610 tests (performed in their own directory), these programs are no
9611 longer visible. In other words, the results is confusing and
9612 useless.
9613 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9615 2002-01-24 Akim Demaille <akim@epita.fr>
9617 Version 2.52g.

9626 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
9627 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
9628 Bourne. Use /bin/sh.
9629 From Andreas Buening.
9631 2002-01-24 Akim Demaille <akim@epita.fr>
9633 * config/config.guess, config/config.sub, config/texinfo.tex:

9643 Automake.
9645 2002-01-24 Akim Demaille <akim@epita.fr>
9647 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
9648 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
9649 Reported by Geir Ove Myhr.
9651 2002-01-21 Akim Demaille <akim@epita.fr>
9653 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
9655 2002-01-21 Akim Demaille <akim@epita.fr>
9657 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
9658 message on invalid options.
9659 * bin/autom4te.in (parse_args): Don't use
9660 Autoconf::General::getopt with non valid options.
9662 2002-01-17 Jim Meyering <meyering@lucent.com>
9664 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
9665 $ac_cv_exeext so we don't use an old, invalid, cached value.
9667 2002-01-11 Akim Demaille <akim@epita.fr>
9669 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
9670 Meyering.

9678 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
9679 package.m4, since is really depends upon configure.ac, not
9680 configure.
9681 * doc/autoconf.texi (testsuite Scripts): Adjust.
9682 * tests/Makefile.am (package.m4): New.
9683 EXTRA_DIST it since its a source.
9685 2002-01-06 Akim Demaille <akim@epita.fr>
9687 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9688 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9689 and PACKAGE_BUGREPORT from here...
9690 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9691 arguments.
9692 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
9693 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
9694 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
9695 * tests/tools.at (autoheader): Adjust.
9696 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
9698 2002-01-06 Akim Demaille <akim@epita.fr>
9700 * bin/autoscan.in (scan_file): Use `&used'.
9702 2002-01-03 Akim Demaille <akim@epita.fr>
9704 * doc/autoconf.texi (Output): Improved wording regarding use of
9705 AC_OUTPUT.
9706 From Olly Betts.

9710 * doc/autoconf.texi (Function Portability): Add notes on sscanf
9711 sometimes needing writable input.
9713 2001-12-17 Jim Meyering <meyering@lucent.com>
9715 * doc/autoconf.texi (New Macros): Tweak wording.
9717 2001-12-14 Akim Demaille <akim@epita.fr>
9719 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9720 trailing files, don't apply `-rf' to files which might not be
9721 created by configure (core, core.*, and *.core), but just `rm -f'.
9722 Suggested by Jonathan Kamens.
9724 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9726 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
9728 2001-12-14 Akim Demaille <akim@epita.fr>
9730 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
9732 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

9748 2001-12-12 Kevin Ryde <user42@zip.com.au>
9750 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
9751 forbidden file descriptors table.
9753 2001-11-26 Akim Demaille <akim@epita.fr>
9755 * bin/autoscan.in (%c_keywords): Build it at top level.
9756 Map to 1 in order to simplify its uses.
9758 2001-11-26 Akim Demaille <akim@epita.fr>
9760 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
9761 Remove $filepath, useless.
9762 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
9763 variables, they are really part of the tokens.
9764 Split the input line on spaces and then look for tokens.
9765 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9766 because of `lex$U.$(OBJEXT)'.
9767 (&scan_files): Use "@list" instead of join.
9768 * doc/Makefile.am (CLEANFILES): Add *.fns.
9770 2001-11-26 Akim Demaille <akim@epita.fr>
9772 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
9773 Remove, replaced by...
9774 * tests/wrappl.in: Be common for all the Perl executables.
9775 In particular autoscan and autoheader want -I.
9776 * configure.ac: Adjust.
9777 * lib/autoscan/headers: errno.h is portable.
9779 2001-11-26 Akim Demaille <akim@epita.fr>
9781 * bin/autoscan.in (used): New.
9782 Use it.
9784 2001-11-26 Akim Demaille <akim@epita.fr>
9786 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
9787 directives.
9788 (&scan_sh_file): Remove a duplicate pattern.
9789 (&check_configure_ac): Use long options.
9790 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
9792 2001-11-26 Akim Demaille <akim@epita.fr>
9794 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
9795 Before, having a line containing the opening of a multi line
9796 comment made the whole line be ignored.
9798 2001-11-26 Akim Demaille <akim@epita.fr>
9800 * doc/autoconf.texi (Using an Autotest Test Suite): New.
9801 (testsuite Scripts): Be one of its subsection.
9802 (Autotest Logs): New.
9804 2001-11-26 Akim Demaille <akim@epita.fr>
9806 Test groups are now run two directories deeper.
9808 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
9809 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
9810 at_top_builddir.
9811 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
9812 top_srcdir, builddir and top_builddir.
9813 Use `at_*dir' relatively to the directory containing the
9814 suite, use `*dir' when relatively to the current group dir.
9816 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
9818 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
9819 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
9820 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
9821 spelling errors.
9823 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9825 * doc/autoconf.texi (Using System Type): Add an example of `case
9826 $host' usage so people quit using `case $target' everywhere.
9828 2001-11-22 Akim Demaille <akim@epita.fr>
9830 * doc/autoconf.texi (Installation Directory Variables): Englishoes
9831 spotted by Jim Meyering.
9833 2001-11-16 Paul Eggert <eggert@twinsun.com>
9835 This patch implements a `long double' suggestion by Oliver Kiddle.
9837 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9838 static, to catch errors if the value isn't known at compile-time
9839 and the compiler supports dynamic arrays. Change its name from
9840 `_array_' to `test_array' to avoid potential name clashes.
9841 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9842 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9843 better than double. Catch a bug in GCC 2.95.2 x86.
9844 * doc/autoconf.texi (C Compiler): Document the above.
9845 * NEWS: Likewise.
9847 2001-11-13 Akim Demaille <akim@epita.fr>
9849 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9850 hand.
9851 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9853 2001-11-13 Akim Demaille <akim@epita.fr>
9855 * lib/autotest/general.m4 (AT_INIT): After having run the test
9856 group, go back to the initial directory, not to at_suite_dir.
9858 2001-11-13 Akim Demaille <akim@epita.fr>
9860 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9861 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9862 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9863 option.
9864 (AT_CHECK_CONFIGURE): Use absolute paths.
9865 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9866 The problem is still the old one: there is no means in M4 (that I
9867 know about) to create a defining macro, because there is no means
9868 to create `$1' etc., therefore, the defining macro ``swallows''
9869 all the arguments meant to the defined macro.
9871 2001-11-13 Akim Demaille <akim@epita.fr>
9873 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9874 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9875 configure.ac.
9876 * tests/aclocal.m4: Remove, as it is no longer used.
9878 2001-11-13 Akim Demaille <akim@epita.fr>
9880 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9881 variable names when referring to a single test group, or to
9882 `suite' when referring to the whole test suite.
9883 `at_last_test' is removed: m4 compute at_format itself.
9884 (at_stdout, at_stder1, at_stderr): New variables.
9885 (AT_CHECK): Use them.
9887 2001-11-13 Akim Demaille <akim@epita.fr>
9889 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9890 in PATH.
9891 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9892 Do it as soon as a test fails, don't wait till the end of the test
9893 suite.
9894 Don't remove $as_me.[0-9]*, since these files no longer exist.
9896 2001-11-13 Akim Demaille <akim@epita.fr>
9898 * tests/tools.at: Use absolute paths, since we are no longer run
9899 in place.
9901 2001-11-13 Akim Demaille <akim@epita.fr>
9903 Now that tests are running in their own private dir, there is no
9904 need to list the files to remove at the end of tests groups.
9906 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
9907 (AT_data_files, at_data_files): Remove.
9908 (AT_CLEANUP, AT_DATA): Simplify.
9909 (AT_INIT): Adjust.
9910 Remove the group dir if !debug && !failed.
9911 * tests/atspecific.m4: Adjust.
9913 2001-11-13 Akim Demaille <akim@epita.fr>
9915 Start a new layout for Autotest: `testsuite' creates
9916 `testsuite.dir' in which the at-check-line etc. files are to be
9917 found, and `testsuite.dir/003' where the test group 3 is run.
9919 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
9920 at_check_line_file, at_format, at_test_normalized, at_group_dir
9921 are new variables.
9922 Create the directories.
9923 Use absolute paths for at- files.
9924 (AT_CHECK): Adjust.
9926 2001-11-11 Michael Matz <matz@kde.org>
9928 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
9929 (m4_car2): New.
9930 (m4_car): Properly quote arguments.
9932 2001-11-13 Akim Demaille <akim@epita.fr>
9934 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9935 with stricter rules on LIBOBJS.
9937 2001-11-12 Paul Eggert <eggert@twinsun.com>
9939 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9940 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9941 __PROTOTYPES too.
9943 2001-11-12 Akim Demaille <akim@epita.fr>
9945 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9947 2001-11-12 Akim Demaille <akim@epita.fr>
9949 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9950 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
9951 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9952 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9953 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9954 specify to what the macro should be defined (typically to 1).
9956 2001-11-12 Akim Demaille <akim@epita.fr>
9958 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9959 From Jim Meyering.
9961 2001-11-12 Akim Demaille <akim@epita.fr>
9963 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9964 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
9965 definition used by Automake where LEX is +/- "${missing} lex" and
9966 `missing' itself contains variables.
9968 2001-11-12 Akim Demaille <akim@epita.fr>
9970 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
9971 Now that M4sh pushes BODY, the comments were output at the end of
9972 the test suites.
9974 2001-11-08 Akim Demaille <akim@epita.fr>
9976 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
9977 that we can trace macros from aclocal.m4.
9978 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
9979 obsoleted, and redirect to the former anyway.
9980 Reported by Ralf Corsepius.
9982 2001-11-08 Akim Demaille <akim@epita.fr>
9984 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
9985 processed only if present.
9986 * tests/torture.at (Configuring subdirectories): Use autoreconf
9987 instead of successive calls to autoconf.
9988 Add a nonexistent subdirectory to exercise the patch above.
9989 Reported by Ralf Corsepius.
9991 2001-11-08 Kevin Ryde <user42@zip.com.au>
9993 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
9994 doesn't accept .S files.
9996 2001-11-07 Akim Demaille <akim@epita.fr>
9998 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
9999 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10000 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10001 * bin/autom4te.in (warn_forbidden): New.
10002 (handle_output): Use it.
10003 Read m4_pattern_forbid with messages.
10005 2001-11-05 Akim Demaille <akim@epita.fr>
10007 * bin/autom4te.in (--normalize): Remove.
10008 * lib/autom4te.in: Adjust.
10010 2001-11-05 Akim Demaille <akim@epita.fr>
10012 * tests/Makefile.am (testsuite): Rename this target as...
10013 ($(TESTSUITE)): this.
10014 From Nicolas Joly.
10016 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10018 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10019 the --prefix option, also remove it's argument.
10021 2001-11-05 Akim Demaille <akim@epita.fr>
10023 * doc/autoconf.texi (testsuite Invocation): Update.
10024 (Writing testsuite.at): Update.
10026 2001-11-03 Akim Demaille <akim@epita.fr>
10028 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10030 2001-11-03 Akim Demaille <akim@epita.fr>
10032 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10033 (&file_name_is_absolute): New, wrappers around routines from
10034 File::Spec.
10035 Use and export them.
10036 (&find_configure_ac): Optionally take a directory where to look at.
10037 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10038 the arguments.
10039 Default @ARGV to `.', not find_configure_ac.
10040 (&autoreconf): Argument is a directory.
10041 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10042 * doc/autoconf.texi (autoreconf Invocation): Update.
10044 2001-11-03 Akim Demaille <akim@epita.fr>
10046 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10047 (@export_forward_subs): New.
10048 Add basename, dirname, and fileparse.
10049 (@EXPORT): Adjust.
10050 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10051 Don't look for aclocal flags if we already know aclocal is not
10052 used.
10053 Move aclocal.m4t only if it exists.
10054 Reported by Ezra Peisach.
10056 2001-11-03 Akim Demaille <akim@epita.fr>
10058 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10059 passed on command line, defaulting to ./configure.ac if present.
10060 (&maybe_autoreconf, File::Find): Remove, unused.
10061 (&autoreconf): If autoconf is not used, don't try to trace.
10063 2001-11-02 Akim Demaille <akim@epita.fr>
10065 * configure.ac: Bump to 2.52g.
10067 2001-11-02 Akim Demaille <akim@epita.fr>
10069 Version 2.52f.
10071 2001-11-02 Akim Demaille <akim@epita.fr>
10073 * config/config.guess, config/config.sub, doc/standards.texi:
10074 * config/lispdir.m4: Update from masters.
10075 * configure.ac: Bump to 2.52f.
10077 2001-11-02 Akim Demaille <akim@epita.fr>
10079 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10080 Don't run aclocal when aclocal.m4 is not from aclocal.
10081 From Ezra Peisach.
10082 Don't run libtoolize and gettextize if --install is not given.
10084 2001-11-01 Paul Eggert <eggert@twinsun.com>
10086 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10087 be invoked before _AS_LINENO_PREPARE.
10088 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10089 than character ranges.
10091 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10092 invoking AS_BASENAME. Set the locale variables to 'C' if
10093 possible, as POSIX requires this to get the traditional
10094 behavior.
10095 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10097 2001-10-31 Paul Eggert <eggert@twinsun.com>
10099 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10100 with {}, as that triggers a bug in Bash 2.05.
10102 (_AS_LINENO_PREPARE): Use Sed rather than
10103 Awk. Fix the sed prepass to work even if there are multiple
10104 instances of $LINENO on the same line. Do not substitute for
10105 other variables like $LINENOT. Do not check file dates; such a
10106 check is unreliable on sufficiently fast machines, and removing
10107 the check makes the code simpler and more reliable. Check for
10108 output and chmod failures.
10110 * doc/autoconf.texi (Special Shell Variables): Document
10111 the above.
10113 2001-10-31 Akim Demaille <akim@epita.fr>
10115 * tests/Makefile.am (atconfig): Remove this target, Automake
10116 handles it now.
10118 2001-10-31 Akim Demaille <akim@epita.fr>
10120 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10121 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10122 provided, while it is optional.
10123 * configure.ac: Adjust.
10125 2001-10-26 Paul Eggert <eggert@twinsun.com>
10127 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10128 lib/Autom4te/Struct.pm:
10129 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10130 with 5.005_02.
10132 * doc/autoconf.texi (Special Shell Variables): Document some
10133 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10135 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10136 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10137 eval $LINENO is not portable in practice.
10139 2001-10-24 Akim Demaille <akim@epita.fr>
10141 * lib/Autom4te/General.pm (backname): New.
10143 2001-10-24 Akim Demaille <akim@epita.fr>
10145 * m4/: Remove, merged into...
10146 * config/: here.
10148 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10150 * doc/autoconf.texi (Shellology): Mention the problems with bash
10151 2.05's use of ANSI quoting in its `set' builtin.
10153 2001-10-22 Paul Eggert <eggert@twinsun.com>
10155 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10156 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10157 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10158 POSIX decided to standardize on the int flavor of strerror_r.
10159 Always do char* test, as there's no reason not to.
10160 Assign to a char* var, to catch strerror_r that returns int*.
10162 * doc/autoconf.texi (Particular Functions):
10163 Document the above changes. Also, document the fact that
10164 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10166 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10168 2001-10-20 Akim Demaille <akim@epita.fr>
10170 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10171 the executable was missing from the log.
10173 2001-10-20 Akim Demaille <akim@epita.fr>
10175 * lib/Autom4te/General.pm (&update_file): If destination is
10176 unchanged, remove the source.
10177 (&up_to_date_p): Don't be verbose, be debug.
10178 * bin/autoreconf.in: No longer support --m4dir.
10179 (&autoreconf): Display the full path of the configure.ac we are
10180 studying.
10181 Trace it only once.
10182 Be sure to honor --force with gettextize.
10183 Always run aclocal.
10184 * doc/autoconf.texi: Adjust.
10186 2001-10-20 Akim Demaille <akim@epita.fr>
10188 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10189 Remove, dead.
10190 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10191 `intl' is already present, as it refuses unless --force.
10192 (&parse_args): Use -I, --include instead of the old Autoconf
10193 options.
10194 ($localdir, $autoconf_dir): Remove.
10195 (@include): New.
10196 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10198 2001-10-19 Jens Petersen <petersen@redhat.com>

10207 Don't mention `automatically' in addition to `generated'.
10208 * tests/torture.at (#define header templates): Adjust.
10210 2001-10-19 Akim Demaille <akim@epita.fr>
10212 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
10213 comment, explain how to install automatic mode selection.
10214 From Russ Allbery.
10216 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10218 * bin/autoreconf.in (autoreconf): Display the path to the
10219 configure.ac being studied.
10221 2001-10-18 Paul Eggert <eggert@twinsun.com>
10223 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10224 long, to work around a bug in the HP C compiler version HP92453-01
10225 B.11.11.23709.GP.
10227 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10228 (AS_BASENAME_EXPR): New macro.
10229 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10230 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10231 and fall back on 'sed' only if the other two fail. This makes
10232 AS_BASENAME act more like AS_DIRNAME.
10233 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10234 contains white space.
10235 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

10385 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

10468 and invoke a new argument $4 if either is discovered.

10470 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

10512 Raja R Harinath:

10514 Look for the original script, basename($0) is certainly not
10515 enough.
10516 Pass the CLI arguments to `$as_me.lineno'.

10673 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
10674 * bin/autoupdate.in: Ditto.
10675 * bin/autoheader.in: Reworded a few comments.
10676 * bin/autoconf.in: Reworded help text for a few options.
10677 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10678 * bin/autoscan.in, bin/autoupdate.in: Ditto.
10680 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10682 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10683 already have $file). Set output files to binary mode (helps avoid
10684 CR issues on DOSish systems).
10686 2001-09-19 Akim Demaille <akim@epita.fr>
10688 * lib/autotest/general.m4: Englishoes.
10689 From Tim Van Holder and Alexey Mahotkin.
10691 2001-09-18 Paul Eggert <eggert@twinsun.com>
10693 * doc/autoconf.texi (Common Shell Constructs): New node,
10694 documenting AS_DIRNAME.
10695 (Limitations of Usual Tools): Refer to it when discussing dirname.
10696 Also, update discussion of POSIX standard to reflect latest draft.
10698 * lib/autoconf/c.m4:
10699 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
10701 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10702 Do not pass a first argument with leading '-'
10703 to expr, by parenthesizing initial integers that might be negative.
10705 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10706 now merely checks whether it is an error to pass an argument
10707 to getpgrp.
10709 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10710 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
10711 whether it is a (compile-time) error to pass an argument to
10712 getpgrp. This simpler test supports the revised documentation,
10713 and is all that AC_FUNC_GETPGRP's users really need.
10715 2001-09-18 Akim Demaille <akim@epita.fr>
10717 * doc/autoconf.texi (Limitations of Make) <$<>: New.
10719 2001-09-18 Akim Demaille <akim@epita.fr>
10721 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
10722 `{}'.
10723 * lib/autotest/general.m4 (AT_INIT): Adjust.
10725 2001-09-18 Paul Wagland <paul@wagland.net>
10727 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
10728 correctly.
10729 Add test for AS_BASENAME.
10730 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10731 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10732 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10733 * tests/base.at: Fixed the expected responses. The old ones were
10734 one line out...
10735 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10736 the documentation claims it should (and how it behaved in 2.13).
10738 2001-09-18 Akim Demaille <akim@epita.fr>
10740 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
10741 the AC_CONFIG_COMMANDS invocation.
10742 This also solves the name clash problems.
10743 Don't set the package's ID.
10744 * lib/m4sugar/Makefile.am (version.m4): Revamp.
10745 No longer to be shipped.
10746 (version.in): Remove.
10747 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
10748 * lib/autoconf/status.m4: Adjust.
10749 Use `m4_PACKAGE_STRING'.
10750 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
10751 the only optional argument is the name of the test suite.
10752 Expect `package.m4' to define the package signature.
10753 * lib/autom4te.in (Autotest): Add `package.m4?'.
10754 * tests/Makefile.am (package.m4): New.
10755 * tests/suite.at: ifnames is a victim.
10757 2001-09-18 Akim Demaille <akim@epita.fr>
10759 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
10760 AC_LIBSOURCE, AC_CONFIG_FILES.
10761 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
10762 program version string doesn't match the package's.
10763 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
10764 after `(cached)'.
10766 2001-09-17 Paul Eggert <eggert@twinsun.com>
10768 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10769 Allow expression to return any value that can fit into unsigned long
10770 (not int, as before). Check for output errors.
10772 2001-09-17 Bruno Haible <haible@ilog.fr>
10774 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10775 Always include <stdio.h> and <stdlib.h>. Evaluate
10776 the expression in an extra function before these includes. Call
10777 fprintf "%d" only after ensuring the argument is of type 'int'.
10778 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
10780 2001-09-17 Paul Eggert <eggert@twinsun.com>
10782 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10783 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10784 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10785 when they don't exist.
10787 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
10788 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
10789 need it.
10791 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
10792 version with the version used by fileutils 4.1, except use
10793 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
10794 we don't need it.
10796 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
10798 2001-09-13 Akim Demaille <akim@epita.fr>
10800 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
10801 _first_.
10802 Reported by Gerrit P. Haase.
10804 2001-09-13 Akim Demaille <akim@epita.fr>
10806 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
10807 m4_defn'ing is valid.

10813 Use it.

10822 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
10823 Likewise.

10826 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
10827 AT_tests_all for consistency.
10828 Set at_victims.
10829 (AT_VICTIMS): Similar to AT_KEYWORDS.
10830 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
10832 2001-09-13 Akim Demaille <akim@epita.fr>
10834 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
10836 2001-09-13 Akim Demaille <akim@epita.fr>
10838 * lib/autotest/general.m4 (AT_INIT): Create and remove
10839 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
10840 test suites can cohabit.
10842 2001-09-13 Akim Demaille <akim@epita.fr>
10844 * tests/mktests.sh: Don't output banners for empty test files.
10846 2001-09-13 Akim Demaille <akim@epita.fr>
10848 Test suites can be run independently of configure.

10950 2001-09-05 Akim Demaille <akim@epita.fr>

10953 the maintainer is dumb enough to do that...
10955 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
10956 excellence in M4 quotation: consider `__file__' is active.

10989 New, extracted from main.
10990 Use IO::File wherever possible.

10993 Don't invoke `_au_disable', since ac was not loaded, but just

11023 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11024 (testsuite Scripts): There is no such thing as `atconfig.in'.

11029 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

11042 2001-08-31 Akim Demaille <akim@epita.fr>
11044 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11045 debug scripts, in particular passing explicitly listed tests to
11046 run is stupid.

11050 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11051 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11052 Use directly autom4te, not autoconf.

11079 the time stamps.

11119 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11120 optionally `FILE'.
11121 Use -e, not -f, since /dev/null for instance is OK.
11122 (&parse_args): Adjust.
11123 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11125 2001-08-31 Akim Demaille <akim@epita.fr>
11127 * configure.ac: Also find tested executables in bin.
11128 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11129 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11130 installed peer executables, only PATH is allowed to resolve it.
11131 Pass `autoconf_dir' via options, not via invisible envvars.
11132 * lib/Autom4te/General.pm (&find_peer): Remove.
11133 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11134 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11135 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11136 find the executables for it.
11137 * tests/Makefile.am: Major cleanup. Too lazy to document...
11138 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11139 We only need PERL.
11140 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11141 indeed related to running the test suite, while passing
11142 --autoconf-dir and others is related to running non installed
11143 Autoconf executables. So don't do that, leave it to...
11144 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11145 * tests/autoscan: New.
11146 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11147 refer to library files: rely on --language.
11149 2001-08-29 Akim Demaille <akim@epita.fr>
11151 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

11154 2001-08-29 Akim Demaille <akim@epita.fr>
11156 * doc/autoconf.texi: Strip the @nodes.
11157 Suggested by Paul Eggert.

11160 2001-08-29 Akim Demaille <akim@epita.fr>
11162 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11163 Suggested by Paul Eggert.
11165 2001-08-29 Akim Demaille <akim@epita.fr>
11167 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11168 download in a tmp dir.
11170 2001-08-29 Akim Demaille <akim@epita.fr>
11172 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

11191 * lib/autotest/general.m4: Use
11192 foo=`(command) 2>/dev/null`
11193 not
11194 foo=`command` 2>/dev/null
11195 (at-devnull): Rename as...
11196 (AT-devnull): this.
11197 (--clean): Remove AT-* files too.

11254 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11255 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11256 readable.
11257 Adjust callers.
11258 * doc/autoconf.texi (Configuration Actions): Document the vars
11259 available in commands.
11260 Emphasize the risks of collisions in init-cmds.

11291 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.

11293 -> ac_dir).

11295 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.

11327 * m4/strip.m4: New.

11342 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11343 the name of the directory they're in, instead of the filename,
11344 since version.m4 is now in m4sugar, but m4_acversion must not be
11345 classified as an Autoconf macro.
11346 ($input_m4): Don't qualify the path to m4sugar.
11347 Rather, pass autoconf_dir to m4.
11348 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

11433 * NEWS, README, README-alpha, TODO, tests/README: This package is
11434 `Autoconf', not `autoconf' (the executable).
11436 2001-08-20 Akim Demaille <akim@epita.fr>

11441 simplified index node names.
11443 2001-08-20 Akim Demaille <akim@epita.fr>
11445 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the

11453 (Examining Syntax) <AC_TRY_COMPILE>

11485 2001-08-20 Akim Demaille <akim@epita.fr>
11487 Huh!?!?! There are still some user EOF tags used, which prevents
11488 their use in AC_CONFIG_COMMANDS for instance...
11490 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
11491 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
11492 `_CSEOF', or `_ATEOF', as appropriate.

11627 (cvs-dist): depends upon it.
11629 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
11631 * tests/Makefile.am: Use a clean-local rule to remove
11632 autom4te.cache (it's a directory, not a file.
11633 * Makefile.am: Ditto (but maintainer-clean-local).
11635 2001-08-15 Akim Demaille <akim@epita.fr>
11637 * bin/autom4te.in (@m4_warning): New.
11638 (&handle_m4): Use it.
11639 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
11640 warnings are issued at each run.
11641 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
11642 is in the src tree.
11644 2001-08-15 Akim Demaille <akim@epita.fr>
11646 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
11647 don't waste time running `autoupdate --version' works.
11648 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
11650 2001-08-13 Akim Demaille <akim@epita.fr>

11709 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11711 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
11712 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
11713 * doc/autoconf.texi (C Compiler Characteristics): Update
11714 documentation for AC_C_BIGENDIAN.
11716 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11718 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11719 magic values from an object file when cross-compiling.
11720 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11722 2001-08-10 Akim Demaille <akim@epita.fr>
11724 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11725 effects.
11726 Suggested by Russ Allbery.
11728 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11730 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11731 current $prefix to the sub-configures.
11733 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11735 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
11736 extension (needed on BeOS). Reported by Guido van Rossum.
11738 2001-08-09 Akim Demaille <akim@epita.fr>
11740 * bin/autom4te.in ($icache): Load it only if older than autom4te.
11742 2001-08-07 Akim Demaille <akim@epita.fr>
11744 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11745 removed.
11746 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11747 No need to remove the files before and after the each test, before
11748 each test and at the end of the suite is enough.
11749 Display only the children `times', not the shell's.
11750 If the test failed or was skipped, at-times is not available.
11752 2001-08-07 Akim Demaille <akim@epita.fr>
11754 Always produce testsuite.log, including when there are no
11755 failures. This helps getting information on skipped tests, and
11756 duration of the tests. Err, implement the latter btw.
11758 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
11759 Dump information on the first run of each test.
11760 (AT_CLEANUP): Create `at-times' containing the duration of the
11761 test group.
11763 2001-08-07 Akim Demaille <akim@epita.fr>
11765 The use of `dumpstat' revealed that `len' was used although it
11766 should not. m4_text_wrap was using it, but in the Autoconf world
11767 where it is legal. Hence (i) test M4sh in its own world, not
11768 Autoconf's, and (ii), ahem, fix the bug :)
11770 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11771 does not like `' instead of [].
11772 (AT_INIT): Forbid `^_?AT_'.
11773 And don't output such tokens.
11774 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11775 `script.as', and `autom4te.cache'.
11776 Remove `empty' and `macro' which are no longer used.
11777 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11778 * tests/m4sugar.at: Use it.
11779 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11781 2001-08-07 Akim Demaille <akim@epita.fr>
11783 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
11785 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
11787 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
11789 2001-08-04 Akim Demaille <akim@epita.fr>
11791 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
11792 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
11793 AC_TRY_LINK.
11794 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
11795 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
11796 (AC_F77_MAIN): Likewise.
11798 2001-08-04 Akim Demaille <akim@epita.fr>
11800 Don't rely on M4sugar outputting the patterns in files, since we
11801 might process the output _without_ running m4, hence without these
11802 files.
11804 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
11805 * bin/autom4te.in (@Request::includes): Remove, unused.
11806 (@Request::source): Rename as...
11807 (@Request::input): this.
11808 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
11809 (&handle_output): Fetch the patterns from the traces.
11810 `$forbidden' and `$allowed' are constant: use m//o.
11811 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
11812 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
11814 2001-08-04 Akim Demaille <akim@epita.fr>
11816 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
11817 autoconf', i.e., in addition to caching traces, cache the output.
11819 * bin/autom4te.in (Request::cache): Rename as...
11820 (Request::id): this.
11821 ($cache, $icache, $tcache, $ocache): New.
11822 (&handle_m4): Save M4 output in the cache instead of $tmp.
11823 (&handle_output): Adjust.
11824 (&up_to_date_p): Check that the output cache is up to date too.
11825 (top level): Run `&handle_m4' iff force or the cache is invalid.
11826 Run `&handle_output' if the output cache is more recent.
11828 2001-08-04 Akim Demaille <akim@epita.fr>
11830 * bin/autom4te.in ($force): New.
11831 (&parse_args, &print_usage): -f, --force is a new option.
11832 (&handle_output): CPP directives might have spaces after `#'.
11833 (&parse_args): The first file only can be frozen.
11835 2001-08-04 Akim Demaille <akim@epita.fr>
11837 Don't let autom4te compute the `include' traces several times:
11838 first check that the trace cache file is up to date, and then
11839 compare its timestamp with that of the output.
11841 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
11842 the preamble. Don't require 5.005 as Autom4te::General does it,
11843 and better yet (use `use', not `require'!).
11844 * lib/Autom4te/Struct.pm: Rename the last occurrences of
11845 Class::Struct as Autom4te::Struct.
11846 * lib/Autom4te/General.pm (File::stat): Use it.
11847 (&mtime): New, export it.
11848 * bin/autom4te.in: Use it.
11849 Declare `$req' is invalid if it is outdated.
11850 Don't declare it valid before saving it if something went wrong.
11852 2001-08-04 Akim Demaille <akim@epita.fr>
11854 Autom4te shall not encode Autoconf data, and preselecting traces
11855 must be proposed to the users.
11857 * bin/autom4te.in (@required_trace): Remove.
11858 (@preselect): New.
11859 (&parse_args, &print_usage): -p, --preselect is a new option.
11860 (&up_to_date_p): Adjust.
11861 * bin/autoconf.in: Preselect some Autoconf macros.
11863 2001-08-04 Akim Demaille <akim@epita.fr>
11865 * tests/tools.at (autoconf --trace: user macros): Check traces on
11866 macros invoked without arguments, and macros invoked with multiple
11867 lines arguments.
11869 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
11871 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
11872 arguments.
11874 2001-08-03 Akim Demaille <akim@epita.fr>
11876 * bin/autoconf.in ($@): Work around the usual sh bug.
11877 From Nicolas Joly.
11879 2001-08-03 Akim Demaille <akim@epita.fr>
11881 Clean up the handling of the M4 builtins tracing exception.
11883 * bin/autom4te.in (Request::request): Don't complete M4 builtins
11884 trace requests.
11885 (@m4_builtins): Rename as...
11886 (@m4_builtin): this.
11887 (%m4_builtin_alternate_name): New.
11888 (&parse_args): Complete the trace requests with alternate names.
11889 (&handle_traces): Hence no longer do it here.
11890 (&trace_requests): Remove, unused.
11892 2001-08-03 Akim Demaille <akim@epita.fr>
11894 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
11895 m4_if, and m4_wrap.
11897 2001-08-03 Akim Demaille <akim@epita.fr>
11899 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
11900 (m4_divert_pop): Dump the whole diversion stack when a diversion
11901 mismatch happens.
11902 * bin/autom4te.in (&handle_output): Remember of the first
11903 occurrence of a possibly undefined macro, not the last.
11904 Complain about the possibly undefined macros in the same order as
11905 the appear in the output.
11906 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
11907 * tests/tools.at (autoconf: forbidden tokens, basic)
11908 (autoconf: forbidden tokens, exceptions): No longer sort
11909 autoconf's stderr, as it is now deterministic.
11910 Check that `dnl' is caught.
11912 2001-08-01 Akim Demaille <akim@epita.fr>
11914 * configure.ac: Bump to 2.52c.

11926 2001-08-01 Akim Demaille <akim@epita.fr>
11928 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
11929 `die'.
11930 (&END): New.
11931 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
11932 `END', as `Autom4te::General::END' will be triggered.
11933 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
11934 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

12326 compiler, not the preprocessor.
12327 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use

12369 cross-language link tests can be performed successfully.
12370 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
12371 after $LIBS, for consistency; this should be the general rule since
12372 the user may want to link to Fortran libraries that require $FLIBS.
12373 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.
12375 2001-06-29 Pavel Roskin <proski@gnu.org>
12377 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
12378 at-stdout and at-stderr instead of removing the newline
12379 from the echo output, which is not guaranteed to work.
12381 2001-06-28 Jens Petersen <petersen@redhat.com>
12383 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to

12445 2001-06-23 Akim Demaille <akim@epita.fr>
12447 * doc/autoconf.texi (Redefined M4 Macros): New.
12449 2001-06-23 Akim Demaille <akim@epita.fr>
12451 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider
12452 inttypes.h is missing if it conflicts with sys/types.h, as on IRIX

12457 * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): Defer parsing of
