1 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4 * NEWS: Document changes with echo and printf, and the lack
5 of limits on the total size of multi-line values of substituted
6 variables, and the AC_FUNC_FSEEKO fix.
8 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
10 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
11 Writing configure.ac.
12 (Autoconf Input Layout): Renamed from configure.ac Layout.
13 (Recreating a Configuration): Renamed from config.status Invocation.
14 (Obsolete Recreation): Renamed from Obsolete config.status Use.
15 (acconfig Header): Renamed from acconfig.h.
16 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
17 (Writing Testsuites): Renamed from Writing testsuite.at.
18 (Autom4te Cache): Renamed from autom4te.cache.
20 * BUGS: Remove mention of VPATH problem, since it's now documented
21 not to be a bug in the Autoconf build procedure itself, but rather
22 a problem with the proprietary `make' programs.
24 * doc/autoconf.texi (Build Directories): Add a cross reference
25 to VPATH and Make.
27 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
28 * doc/standards.texi: Sync from gnulib.
30 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
31 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
32 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
33 generated automatically.
35 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
37 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
38 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
39 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
41 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
43 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
44 `CEOF$ac_eof' special marker, the awk script cannot contain a
45 line matching `^CEOF', so this is not needed any more.
46 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
47 special marker in the test.
49 2006-12-06 Stepan Kasal <kasal@ucw.cz>
51 * tests/tools.at (autom4te preselections): Use `find -newer';
52 remove one of the sleeps.
54 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
55 more readable, using ...
56 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
58 * doc/autoconf.texi (autoheader Invocation): Do not double-
59 quote the parameter of `AH_BOTTOM' in the example.
61 2006-12-05 Stepan Kasal <kasal@ucw.cz>
63 * doc/autoconf.texi (Configuration Headers): Remove the
64 example with multiple input files.
65 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
66 multiple input files.
68 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
70 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
71 creating the awk substitution script, handle one input line at a
72 time, so that the maximum length of a substituted (multi-line)
73 value is not limited by the size of the sed pattern space.
74 The trade-off is a slightly repetitive sed script.
75 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
76 can only have up to 7 characters, due to Solaris 10 /bin/sed.
77 * tests/torture.at (Substitute a 2000-byte string): Increase the
78 test with several long lines, they should not be caught by sed
79 limits any more.
81 * tests/tools.at (autom4te preselections): New test, to flag
82 entries missing from autom4te.cfg.
83 Report by David Byron <dbyron@hheld.com>.
85 * tests/torture.at (Substitute a 2000-byte string): Actually use
86 AC_PROG_AWK, so the last change works as intended.
87 (Substitute and define special characters): Likewise.
88 (Substitute a newline): Likewise.
90 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
91 instead of `awk' consistently.
92 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
93 * tests/torture.at (Torturing config.status): Test both the
94 result of AC_PROG_AWK and plain awk.
95 (Substitute a 2000-byte string): Likewise.
96 (Substitute and define special characters): Likewise.
97 (Substitute a newline): Likewise.
99 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
101 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
102 can be assigned to a function pointer. Problem reported by
103 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
104 part of a patch by Ralf Wildenhues in that same bug report.
106 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
108 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
109 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
111 2006-12-01 Eric Blake <ebb9@byu.net>
113 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
114 cross-compiling from cygwin to mingw.
115 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
116 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
117 to lib/autoconf/c.m4.
119 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
121 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
122 string for more reliable failure. Wrap the entire test that
123 causes the broken Solaris printf to dump core, in a subshell,
124 so the segmentation fault message is reliably suppressed.
125 Fix shell expansion errors by using /usr/ucb/echo always;
126 avoid an error on systems without it by another subshell.
127 Avoid m4 expansion of `$1'. Set the zeroth argument of the
128 subshell-$as_echo to `as_echo', for better error message.
130 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
132 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
133 `BASH_SOURCE' contain a newline, set them to empty, as they may
134 not be unset.
136 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
138 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
139 years and is too hard to maintain now. The last straw was
140 reported by Jerker Baeck in
141 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
142 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
143 * doc/autoconf.texi (Particular Functions): Move
144 AC_FUNC_SETVBUF_REVERSED from here...
145 (Obsolete Macros): ... to here. Say that it does nothing now.
146 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
147 Turn into (almost) a no-op.
149 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
150 (AC_C_VOLATILE):
151 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
152 These macros are obsolescent and new applications shouldn't need them.
153 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
154 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
155 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
156 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
157 (AC_FUNC_VPRINTF): Likewise.
158 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
159 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
160 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
162 * doc/autoconf.texi (Setting Output Variables): Mention that
163 @VAR1@VAR2 has unspecified behavior. Problem reported by
164 Ralf Wildenhues.
165 * NEWS: Mention this.
167 * Makefile.am: Put only a single '#' into the copyright notice,
168 so that it's also present in the output file. Standardize wording
169 in makefile copyright notices to match GNU coding standards.
170 * bin/Makefile.am: Likewise.
171 * doc/Makefile.am: Likewise.
172 * lib/Makefile.am: Likewise.
173 * lib/freeze.mk: Likewise.
174 * lib/autoconf/Makefile.am: Likewise.
175 * lib/autoscan/Makefile.am: Likewise.
176 * lib/autotest/Makefile.am: Likewise.
177 * lib/m4sugar/Makefile.am: Likewise.
178 * man/Makefile.am: Likewise.
179 * tests/Makefile.am: Likewise.
180 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
181 one-line file.
183 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
185 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
186 in the sed script that mangles the awk script: delete up to the
187 first exclamation mark only.
188 * tests/torture.at (Substitute and define special characters):
189 Test '!' too.
191 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
193 Rewrite config files generation: avoid quadratic growth in
194 the number of substituted variables by using awk instead of sed
195 for the bulk of the substitutions.
196 * NEWS: Mention this.
197 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
198 forbidden in the output (and thus input) file.
199 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
200 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
201 generate just one large awk script for substitutions,
202 eliminating much of the earlier complexity, while adding some
203 new complexity. Only expand the substitution templates at
204 configure time, for smaller configure script size. If
205 _AC_SUBST_FILES are used, test 'awk' for working getline support
206 at config.status time. If absent, interpolate through the
207 shell. The awk script was written with much help
208 from Paolo Bonzini and Paul Eggert.
209 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
210 (_AC_SED_FRAG_NUM): Likewise.
211 (_AC_SUBST_CMDS): Renamed from...
212 (_AC_SED_CMDS): ...this.
213 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
214 * tests/torture.at (Substitute a 2000-byte string): Also
215 substitute a line with 1000 words, and a variable with several
216 long lines.
217 (Substitute and define special characters): Test awk special
218 characters, and put substitution input strings `@foo@' in the
219 output, to test that no recursion happens; test several other
220 combinations from Paolo Bonzini.
222 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
224 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
225 that replaced echo with AS_ECHO where this wasn't necessary.
226 Problem reportd by Ralf Wildenhues.
227 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
228 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
229 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
231 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
233 * lib/freeze.mk (GREP): Removed, no need to initialize this.
235 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
237 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
238 that traditional Awk lacks 3-arg "split". It has it.
239 Mention that FS must be a single character, and a few other
240 99-byte limits of traditional Awk.
241 Mention that if (i in a) doesn't work with traditional Awk.
243 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
245 * tests/autotest.at (BSx641-newline in command):
246 (BS-BS-newline in command, BSx640-newline in command):
247 (Newline-CODE-BS-newline in command):
248 (Single-quote-BS-newline in command):
249 (Single-quote-newline-BS-newline in command):
250 Use printf '%s\n' instead of echo, for portability to hosts
251 where echo interprets backslashes. This will break on hosts
252 that lack printf, but for now let's assume all such hosts
253 are dead (if not, we should get reports of test failures).
255 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
257 'echo' has some portability problems, when given a first argument
258 with a leading '-', or when given any argument containing '\'.
259 Avoid using 'echo' in these cases.
260 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
261 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
262 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
263 * lib/autotest/general.m4 (AT_INIT): Likewise.
264 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
265 argument might be unportable.
266 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
267 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
268 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
269 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
270 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
271 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
272 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
273 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
274 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
275 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
276 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
277 (AC_PROG_MAKE_SET): Likewise.
278 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
279 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
280 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
281 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
282 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
283 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
284 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
285 * bin/autoconf.as: Redo verbose flag implementation, as the old
286 scheme wouldn't work with AS_ECHO.
287 * lib/autotest/general.m4 (AT_INIT): Likewise.
288 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
289 Don't use ECHO_T, since ECHO_N is now reliable.
290 * lib/autotest/general.m4 (AT_INIT): Likewise.
291 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
292 rather than using a here-document to put the script into a file.
293 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
294 use AS_ECHO.
295 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
296 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
297 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
298 bug, but we might as well stop using ECHO_N and ECHO_C internally.
299 * lib/autotest/general.m4 (AT_SETUP): Likewise.
300 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
301 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
302 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
303 operand, as AS_ECHO requires. Avoid double file name expansion.
304 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
305 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
306 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
307 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
308 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
309 Double-quote strings that would otherwise contain M4 comments.
310 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
312 * configure.ac (AC_INIT): Bump to 2.61a.
313 * NEWS: Likewise.
315 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
317 Version 2.61.
319 * configure.ac (AC_INIT): Bump to 2.61.
320 * NEWS: Likewise.
322 * tests/autotest.at (Macro with backslash in a test title):
323 Comment out for now, as this tests neither fails nor passes
324 reliably. Problem reported by Ralf Wildenhues.
326 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
328 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
329 in previous change, which caused test failures.
331 2006-11-16 Stepan Kasal <kasal@ucw.cz>
333 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
334 code for --enable, --disable, --with, and --without to...
335 (_AC_INIT_PARSE_ENABLE): ... a new macro.
336 * doc/autoconf.texi (Package Options):
337 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
339 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>

398 first argument may also contain dots.
400 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
402 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
403 benefit of platforms like Solaris+GCC where it is common to have a
404 non-working g++ installation.
406 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

412 ./micro-suite.
414 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
416 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
417 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
418 Imported from a similar patch to gnulib by Bruno Haible.
420 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
422 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
423 * doc/autoconf.texi (C Compiler): Document them.
424 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):
425 New macros, taken from gnulib.
427 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>

431 Matthew Woehlke.
433 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
435 * tests/torture.at (Configuring subdirectories): Do not skip
436 Automake 1.10 nor future Automake 11.1 (sic).
438 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
439 and Stepan Kasal <kasal@ucw.cz>
441 Handle special characters in test case titles correctly.
442 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
443 properly.
444 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
445 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
446 argument. Extend to check titles printed by ./micro-suite and
447 ./micro-suite -l and the title in micro-suite.log.
448 (Backquote in a test title,
449 Single-quote in a test title,
450 Double-quote in a test title): Don't expect failure anymore.
451 (Backslash in a test title): Put a non-whitespace character after the
452 backslash so that Bourne shells might actually see it as an escape
453 sequence.
454 (Brackets in a test title,
455 Pound in a test title,
456 Comma in a test title,
457 Quoted Macro in a test title,

462 Macro with backslash in a test title): New tests expected to fail.
463 * tests/torture.at (#define header templates): M4-quote this title in
464 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
465 The visible effect was a stray [] in the testsuite output.
467 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
469 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
470 `trap ... 0' inside a function, for AIX sh.
472 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
474 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
475 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
476 5363) simply issues a warning when dividing by zero at compile
477 time. Problem reported by Elias Pipping.
479 2006-10-26 Eric Blake <ebb9@byu.net>
481 * THANKS: Update.
482 * doc/autoconf.texi (Evaluation Macros): Improve the example to
483 show effect on macros that expand with commas.
484 Reported by Joel E. Denny.
486 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
487 Also work with M4 1.4.8.
489 2006-10-25 Paul Eggert <eggert@cs.ucla.edu>
491 * doc/autoconf.texi (Slashes): Document Tru64 4.0 bug reported by

499 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
501 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm
502 needs operands on NetBSD 2.0.2. Problem reported by Bruno Haible.
504 2006-10-24 Stepan Kasal <kasal@ucw.cz>
506 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
508 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
510 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
511 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
512 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
513 reported by Nelson H. F. Beebe for Coreutils 6.4.
515 * tests/tools.at (autoconf --trace: user macros): Remove test
516 for tracing multiline macros, since m4 1.4.7a uses a different
517 way to number lines. Problem reported by Ralf Wildenhues.
519 2006-10-24 Stepan Kasal <kasal@ucw.cz>
521 * bin/autom4te.in (handle_m4): Do not redirect stdin to
522 /dev/null since the heuristics for interactive behaviour was
523 fixed in CVS m4.
525 * bin/autom4te.in: With --force, always refresh the output
526 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
528 * bin/autoconf.as: Fix the verbose message at the end.
530 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

541 * build-aux/texinfo.tex: automake 1.10
543 * NEWS: Remove AC_CACHE_CHECK_INT.
544 * doc/autoconf.texi (Caching Results): Likewise.
545 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
546 AC_CACHE_CHECK_INT, since it's no longer public.
547 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
548 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
550 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

559 m4_mkstemp.

568 Standards.

576 2006-10-14 Stepan Kasal <kasal@ucw.cz>
578 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
579 looking for special shell characters.
580 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
581 macro defined by AS_VAR_PUSHDEF before passing it as a
582 parameter.
583 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
584 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

593 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
595 (Imported from Automake.)
596 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
597 which incorrectly sets the mode of an existing destination
598 directory. In some cases the unpatched install-sh could do the
599 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
600 system. We hope this is rare in practice, but it's clearly worth
601 fixing. Problem reported by Alex Unleashed in
602 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
603 Also, don't bother to check for -m bugs unless we're using -m;
604 suggested by Stepan Kasal.
606 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
608 Import this change from Automake:
610 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

612 is enabled by default with gnu and gnits strictness.
613 Report from Bruno Haible.
615 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
616 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
617 gnu and gnits modes.
619 Import this change from Config:
621 2006-09-20 Ben Elliston <bje@gnu.org>
622 * build-aux/config.sub (score, score-*): New.
624 Import this change from Gnulib:
626 2006-09-16 Karl Berry <karl@gnu.org>
627 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
628 to avoid sectioning errors.
630 Import these changes from Texinfo:
632 2006-10-04 Karl Berry <karl@gnu.org>
633 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
634 (\quoteexpand): rename to \rquoteexpand.
635 (\codequoteleft): new def, to look for @set codequotebacktick.
636 (\lquoteexpand, \quoteexpand): new defs.
637 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
638 (\code): must use new \...Char values, since now ` is active.
640 2006-08-26 Karl Berry <karl@gnu.org>
641 * build-aux/texinfo.tex (\textdegree): New command.
643 2006-08-12 Karl Berry <karl@gnu.org>
644 * build-aux/texinfo.tex (error \box0): smaller font.

648 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
650 2006-10-13 Stepan Kasal <kasal@ucw.cz>
652 * doc/autoconf.texi (Autoheader Macros): Warn that the text
653 added to the template can get mangled.
655 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
657 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
658 include the default headers, and redefine obstack_chunk_alloc
659 and obstack_chunk_free. Fixes false failure with glibc.
661 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
663 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
664 for backward compatibility with Libtool 1.5.22. Problem reported
665 by Ralf Wildenhues.
667 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
669 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
670 AC_PROG_CC.
671 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
673 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
675 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
676 the NonStop platform.
677 * doc/autoconf.texi (Posix Variants): Likewise.
678 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
680 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
681 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
682 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
683 Use a better substitute, by inspecting the output of "ls"
684 rather than just using ":".
685 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
686 rather than AS_EXECUTABLE_P, since we needn't worry about
687 non-regular files here.
689 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
690 due to configuration hassles with this. See Tonya Underwood's report
691 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
692 * doc/autoconf.texi (Special Shell Variables): Likewise.
694 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
695 Stepan Kasal <kasal@ucw.cz>
697 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
698 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
700 2006-10-11 Stepan Kasal <kasal@ucw.cz>
702 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
703 initialization which is not inherited through the environment
704 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
705 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
707 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
709 * doc/autoconf.texi (Limitations of Usual Tools): Describe
710 problems with mkdir -p -m.
712 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
714 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
715 comment about ac_cpp_err; it was incorrect, and anyway
716 ac_cpp_err is being removed below.
717 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
718 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
719 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
720 nobody uses it.
721 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
722 with werror_flag and conftest.err and so forth. This is more
723 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
724 and anyway the user shouldn't normally want to see this gorp logged.
725 Problem reported by Ralf Wildenhues.
726 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
727 empty, not 'no', since the rest of the code uses 'test -z'.
729 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
731 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
732 Use a single call to AC_DO_TOKENS rather than multiple, for
733 efficiency.
734 (_AC_LINK_IFELSE): Test that resulting file is executable.
735 Problem reported by mwoehlke in
736 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
738 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
739 than creating a file to use with test -x; this is much faster.
741 2006-10-02 Bruno Haible <bruno@clisp.org>
743 * lib/autom4te.in (Automake-preselections): Add
744 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
746 2006-09-27 Stepan Kasal <kasal@ucw.cz>
748 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
749 standard error, `experr' should be used, not `expout'.
751 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
753 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
754 fseeko testing program twice; just use the earlier result.
755 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
756 Set cache var to 'unknown' (not 'no') if leaving the macro unset
757 still doesn't let the program compile.
758 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
759 failed.
761 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
762 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
763 include it, without including anything else.
764 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
765 expressions.
766 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
768 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
770 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
771 `error.h', and include it, for a `error_at_line' prototype.
772 Use a nonempty format string in the link test.
773 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
774 for a declaration of wait3.
776 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
778 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
779 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
780 can apply to constants too, and that it checks for macro defns.
781 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
782 and simply cast the identifier to void. This handles structure
783 values. Problem reported by Ralf Wildenhues.
784 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
786 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
788 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
789 structure, and function symbols.

806 warnings (uninitialized value).
807 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
808 present.
809 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add
810 parentheses.

839 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
840 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
841 --error-output, to avoid warnings with M4 2.0.
843 2006-09-19 Stepan Kasal <kasal@ucw.cz>
845 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be
846 consistent with _AH_CHECK_FUNCS and _AH_CHECK_HEADERS.
847 * lib/autoconf/headers.m4 (AH_CHECK_HEADERS_DIRENT): Likewise.
849 2006-09-15 Stepan Kasal <kasal@ucw.cz>

854 2006-09-14 Stepan Kasal <kasal@ucw.cz>
856 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
857 mistaken comment: the path has to be relative; do not use
858 the path at runtime.
860 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
862 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

866 for both changes.
867 * doc/autoconf.texi (Setting Output Variables): Fix example to
868 not show `--silent' being passed to a `configure' re-run.
870 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
872 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
873 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
874 for the existence of the directory at configure-time. That's
875 too late, anyway. Problem reported by Stefan Seefeld.
877 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
878 7.1.4 /usr/bin/posix/sh described by Tim Rice in
879 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
881 2006-09-11 Stepan Kasal <kasal@ucw.cz>
883 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
884 works with GNU M4 1.4.3 again; make the normalized form
885 match the current m4 message; fix the description.
886 * test/tools.at (autom4te cache): Adapt to the change.
888 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
890 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
891 to catch glibc bug 2821
892 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
894 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
895 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
896 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
897 assume C89.
899 2006-09-08 Stepan Kasal <kasal@ucw.cz>
901 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the
902 preselections ...

915 by Dries Kimpe.
917 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
919 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
920 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
921 accept files with extension `.f'. For consistency, also prefer
922 xlf over f77.
923 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
924 from last patch.

944 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
945 except the first two arguments are reversed.
946 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
947 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
948 caches nor outputs a diagnostic. Suggested by Bruno Haible.

958 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
959 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
960 programs should use their Gnulib counterparts.
961 * doc/autoconf.texi (Particular Functions): Likewise.
962 (Macro Names, testsuite Invocation): Replace uses of these
963 obsolete macros with uses of non-obsolete macros.

987 simplify the code.
989 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
991 Fix Lex library problem reported to us by Julio Garvia.
992 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
993 for the default, which the user can override.
994 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
995 deal with LEXLIB.
996 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
997 didn't work if some values were cached but not others. Test for
998 broken lex libraries like native ia64-hp-hpux11.22; see
999 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1000 work around the problem by preferring an empty LEXLIB to -lfl or
1001 -ll. Let the user set LEXLIB='' to indicate no library needed.
1003 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1004 * README: Likewise.
1005 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

1152 * doc/autoconf.texi (Limitations of Usual Tools): Document sed

1198 compiler complains about it, even if things works after the
1199 complaint. Problem reported by Peter O'Gorman.
1201 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1202 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1203 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1205 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1207 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

1217 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1219 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1220 under AC_C_VOLATILE.
1221 (Volatile Objects): Be a little less skeptical about what

1231 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1232 more globally, since the 2006-06-30 patch didn't suffice. Problem
1233 reported by Keith Marshall. Also, don't bother with builddir2,
1234 since it shouldn't be needed any more.
1236 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1238 * doc/autoconf.texi (Generic compiler characteristics):
1239 Document AC_COMPUTE_INT. Fix wrong statements on Default

1255 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1257 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1258 Require that long long int be at least 64 bits wide. C99 requires
1259 this and enough programs depend on it so we should check for it.
1260 Bruno Haible reports in
1261 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1262 that long long int is 32 bits wide with some nonstandard compilers.
1263 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1265 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1267 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1268 to a nonexistent file, so that we don't have to worry about
1269 a local site configuration that doesn't use /usr/local.
1270 Problem reported by Keith Marshall in
1271 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1273 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1275 * doc/autoconf.texi: Be more consistent about using @acronym with
1276 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1277 quite right (it talked about "OSF/Tru64", even though the
1278 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1279 and it even mentioned "OSF 4"!) and at this point there's little
1280 reason to talk about OSF any more, since it died in 1994.
1281 (Specific Compiler Characteristics): Simplify example of
1282 negative-size array.
1283 (File Descriptors): Reorder to make the text flow better.
1284 Remove joke about "appreciate the various levels"; I didn't get it.
1285 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1286 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1287 (File Descriptors, Limitations of Usual Tools):
1288 Tone down the advice against renaming or removing open files.
1289 (Limitations of Usual Tools): Add a new section, on 'rm'.
1291 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1293 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1294 -lXt in LIBS, idea from Karsten Hopp; this was due since
1295 this change:
1297 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1298 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1299 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1300 (which belong to Xt, not X itself). See Debian bug 327655.
1302 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1304 * configure.ac (AC_INIT): Bump to 2.60a.

1324 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1325 not defined.
1326 * doc/autoconf.texi (Changed Directory Variables): New node,
1327 to document the whole `datarootdir' business a bit better.
1328 * NEWS: Update.
1329 * tests/torture.at (datarootdir workaround): Extend test.
1330 Prompted by report by Alexandre Julliard.
1332 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1334 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility

1336 fix reported by Larry Jones.
1338 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1340 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1341 about literal '${datarootdir}' if a definition is found in the
1342 output file.
1344 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1346 * NEWS: Use "M4" rather than "m4" when appropriate.
1347 Problem reported by Eric Blake.
1348 * doc/autoconf.texi: Likewise.
1349 Use @acronym around BSD, GCC, and GNU when appropriate.
1350 (Why GNU M4): Renamed from "Why GNU m4".
1351 (Redefined M4 Macros): Mention that Posix
1352 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1353 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1354 to int.
1356 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1358 * bin/autom4te.in (handle_output): Do not forbid the empty
1359 pattern.
1360 * tests/tools.at (autoconf: the empty token): New test.
1362 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1364 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1365 calls, so that we do not care whether they are LIFO or FIFO;
1366 in the m4_wrap, do not check which diversion is the topmost
1367 one, just check that the stack is balanced at the end.
1368 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1369 base diversion forever--pop the previous diversion before
1370 opening the new one; consequently, remove the m4_wrap call.
1371 * lib/autotest/general.m4 (AT_INIT): Likewise.
1372 * tests/m4sugar.at: Do not use
1373 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1375 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1376 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1378 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1379 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1380 Rework example of m4wrap token-pasting trouble so that it doesn't
1381 care whether it's LIFO or FIFO.
1382 Fix some "contrary to"s that are awkward in English.
1384 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1386 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1387 to `yes' instead of `int$1_t' if the type is found, for more
1388 consistent configure output (where $1 is the number of bits).
1389 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1390 Suggested by Bruno Haible.
1392 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1393 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1394 with system headers. Report by Bruno Haible.
1396 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1398 * config/config.guess, config/config.sub: Sync from upstream.
1400 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1401 in order to avoid picking up an older installed frozen m4sh.m4f.
1402 Besides an outdated shell startup, this could have been created
1403 by an earlier M4 version with incompatible frozen file format.
1405 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1407 * README: Recommend m4 1.4.4 instead of 1.4.3..
1408 * doc/autoconf.texi: Likewise.
1409 (Special Chars in Names): Say that $(.FOO) is portable, as
1410 suggested by Stepan Kasal.
1411 (Installation Directory Variables, Build Directories):
1412 (Automatic Remaking, Subdirectories, Fortran Compiler):
1413 (Making testsuite Scripts, Defining Directories):
1414 Quote variable usages better.
1415 (Making testsuite Scripts): Add clean-local rule to makefile
1416 snippet, by Eric Blake.
1417 (Installation Directory Variables): Fix table item font.
1418 Reword slightly to clarify. Generalize advice about
1419 not using special characters to include all file-related
1420 vars, not just VPATH.
1421 (Special Chars in Variables): Warn about special characters in
1422 $(srcdir) too.
1423 (Assignments): Clarify default-value example as suggested by
1424 Ralf Wildenhues in
1425 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1426 (Special Shell Variables): Note leading ./ or ../, as suggested
1427 by Eric Blake.
1428 (Limitations of Builtins): Under cd, warn about CDPATH.
1429 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1430 Ralf Wildenhues.
1432 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1434 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1435 `@var', for texi2html.
1436 (Systemology): Some more word wrapping, for DVI output.
1437 (autom4te Invocation): The short option for `--melt' is `-M',
1438 not `-m'.
1440 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1442 * doc/autoconf.texi: More formatting and English tweaks,
1443 many suggested by Ralf Wildenhues.
1444 Reword to avoid "@code{...}'s" and the like, since it's ugly
1445 with Emacs info mode. discontents -> woes.
1446 Put a few "will"s back. time stamp -> timestamp.
1447 side-effect -> side effect.
1449 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1451 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1452 Warn about $@ not persisting. Problem reported by Julien Danjou in
1453 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1454 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1455 Mention other special chars, too.
1457 2006-06-14 Eric Blake <ebb9@byu.net>
1459 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1461 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1463 * doc/autoconf.texi: Some systematic minor improvements, as
1464 follows. Use "makefile" when talking about makefiles
1465 generally (which might be named "makefile" or "Makefile" or even
1466 "foo.mk"), "Makefile" when talking about a specific makefile
1467 called "Makefile". This unclutters the text from weird quotes
1468 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1469 values" rather than "@var{foo}s" and similar constructs containing
1470 "}s". Use "Make rules" rather than "Makefile rules". Minor
1471 English-language improvements. Change the prefix "sub-" to "sub"
1472 and "re-" to "re".
1473 Put blank lines around examples more consistently.
1474 Avoid "rather" and "very" as intensifiers.
1475 Avoid "will" as an auxiliary.
1476 (Limitations of Make): Split this node into....
1477 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1478 (Leading _ in Macro Names, Backslash-Newline-Newline):
1479 (Backslash-Newline Comments, Long Lines in Makefiles):
1480 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1481 (obj/ and Make, make -k Status, VPATH and Make):
1482 (VPATH and Double-colon, $< in Explicit Rules):
1483 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1484 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1485 New nodes, resulting from splitup of Limitations of Make.
1486 All cross-references changed. Raise the top node from
1487 a section to a chapter, and all subnodes accordingly.
1488 Redo the introductory wording to match the new organization.
1489 (Installation Directory Variables): Use an example that is
1490 closer to what Autoconf actually does. Mention that VPATH's
1491 value should not contain metacharacters or white space.
1492 (Fortran Compiler): Fix a VPATH bug in an example.
1493 (Leading _ in Macro Names): Mention that this problem is no longer
1494 of practical concern.
1495 (VPATH and Make): Reword the advice to make it clearer
1496 that Autoconf and Automake support VPATH in non-GNU make, but
1497 many packages have bugs in this area.
1498 ($< in Explicit Rules): Refer to Build Directories rather
1499 than using a (non-VPATH-safe) example.
1500 (Automatic Rule Rewriting): Mention the sort of disaster that
1501 can ensue with Solaris-style rule rewriting with VPATH.
1503 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1505 * doc/install.texi (Compilers and Options): Weaken the
1506 suggestion to use GNU make for VPATH builds.
1508 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1509 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1511 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1512 in regular expression.
1514 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1516 * doc/autoconf.texi (Installation Directory Variables):
1517 Drop extra @samp from `@table @samp' item.
1518 (Limitations of Usual Tools): Comment fix.
1519 Do not nest @samp just to point to other table items.
1520 (Writing testsuite.at) <AT_CHECK>: The second argument to
1521 `@dvar' is already @samp'ed.
1522 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1523 do not use @var in the second argument.
1525 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1527 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1528 $as_shell.exe too. Problem reported by Andreas Buening in
1529 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1531 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1533 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1534 `unused variable' compiler warning, for `-Wall -Werror'.
1535 Reported by Jaap Haitsma in
1536 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1538 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1540 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1541 case the compiler dumps core. Problem reported for
1542 OpenServer 5.0.7 by Tim Rice in
1543 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1544 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1545 Likewise.
1547 2006-06-06 Tim Rice <tim@multitalents.net>.
1549 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1550 "ERROR" only shows up in "make check" output if there is an
1551 error.
1553 2006-06-06 Eric Blake <ebb9@byu.net>
1555 * tests/tools.at (automatically allowed tokens): Fix typo.
1557 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1559 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1561 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1562 typically overflows on x86 CPUs, even though the C standard
1563 requires otherwise.
1565 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1567 * configure.ac (AC_INIT): Bump to 2.59e.
1568 * NEWS: Update.
1570 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1572 Version 2.59d.
1574 * config/texinfo.tex: Sync from upstream.
1576 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1577 seen, invoke libtoolize with `--ltdl' argument.
1578 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1579 * NEWS: Update.
1580 Suggested by Eric Blake.
1582 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1584 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1585 reported by Ralf Wildenhues.
1586 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
1588 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1590 * THANKS: Update.
1592 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1594 * doc/autoconf.texi: Modernize some of the references to Solaris.
1596 2006-06-05 Stepan Kasal <kasal@ucw.cz>
1598 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
1599 message issued by AC_REQUIRE.
1600 * tests/m4sugar.at: Check m4_require's error message.
1601 * tests/base.at: Check AC_REQUIRE's error message.
1602 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1603 to...
1604 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1605 AT_CHECK_M4.
1606 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1607 `expout' as the last parameter.
1608 * tests/tools.at: Adapt to the above change.
1610 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1612 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1613 information about race-free implementations of mkdir.
1615 2006-06-04 Eric Blake <ebb9@byu.net>
1617 * bin/autoreconf.in (help): Document M4 environment variable.
1618 * bin/autoconf.as (Usage): Likewise.
1619 * bin/autom4te.in (help): Likewise.
1620 * doc/autoconf.texi (autom4te Invocation): Likewise.
1622 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1624 * NEWS: GNU make now recommended for VPATH builds.
1625 Mention that some macros are now documented to be obsolescent.
1626 * doc/autoconf.texi:
1627 Prefer "current" to "modern" to describe
1628 currently-used (albeit perhaps old-fashioned) hosts.
1629 Mention which ancient features no longer need to be worried about.
1630 setgid -> set-group-ID
1631 setuid -> set-user-ID (these are the Posix terms)
1632 Fix some misuses of "only".
1633 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1634 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1635 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1636 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1637 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1638 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1639 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1640 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1641 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1642 Mention that these macros are obsolescent.
1643 (Installation Directory Variables): shall -> should
1644 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1645 Mention that it's now safe to use 3 and 4.
1646 (Limitations of Usual Tools): cp -r is now specified by Posix.
1647 Omit longwinded and obsolescent discussion of cp -f.
1648 Modernize discussion of expr, ls.
1649 (Limitations of Make): Modernize discussion of VPATH builds.
1650 Mention $? as a workaround in some cases.
1651 * doc/install.texi (Basic Installation):
1652 Mention "./configure; make; make install" first. Be more
1653 specific about why this file is generic. Remove unnecessary
1654 parens. Remove misleading "only". Remove obsolete advice
1655 about csh. Don't say "configure" takes awhile; say it
1656 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1657 and CC=c99 rather than CC=c89, as these are blessed by current
1658 Posix. Recommend GNU make if doing a VPATH build.
1660 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1662 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1663 examples involving shell prompts.
1665 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1666 and Paul Eggert <eggert@cs.ucla.edu>
1668 * doc/autoconf.texi (Here-Documents): Add details about the
1669 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1670 use "here-documents" instead of "here documents".
1672 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1674 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1676 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1678 * doc/autoconf.texi (File System Conventions): Warn about ":"
1679 anywhere in directory names.
1681 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1683 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1684 about quoting the case statement, just in case.
1685 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1686 was fixed in ksh93g; reported by Ralf Wildenhues.
1688 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1690 * doc/autoconf.texi (System Services): Do not document
1691 overriding EXEEXT via ac_cv_exeext=ext.
1692 (Particular Programs) <AC_PROG_MKDIR_P>:
1693 Document that ${MKDIR_P} understands --.
1694 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1695 comment.
1697 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1699 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1700 argument with leading hyphen. Problem reported by Paul Eggert.
1702 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1704 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1705 about quoting ac_try: quote all of it, if any of it seems suspicious.
1706 This means we don't have to worry about ${ or sed any more.
1707 Also, double-quote the case statement, to work around misuses via
1708 underquoting as reported by Ralf Wildenhues in
1709 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1710 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1711 undocumented and dangerous macro.
1712 Problem reported by Ralf Wildenhues in
1713 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1715 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1717 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1718 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1719 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1721 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1723 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1724 since evidently some packages rely on the old, broken behavior.
1725 Problem reported by Ralf Wildenhues in
1726 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1727 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1728 pre-2006-05-26 definitions, but leave in the comments that
1729 these macros are dangerous and should not be used.
1730 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1731 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1732 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1733 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1734 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1736 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1738 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1739 the use of 'tr', since this is our only use of 'tr'.
1741 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1742 and Paul Eggert <eggert@cs.ucla.edu>
1744 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1745 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1747 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1749 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1750 the output file in the `${datarootdir}' test.
1752 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1753 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1755 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1756 mention of `datarootdir' in the input file(s), but literal
1757 `${datarootdir}' in the output file, and we haven't warned yet,
1758 then warn as well: the user may have (erroneously) used
1759 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1760 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1761 * tests/torture.at (datarootdir workaround): Extend this test.
1762 * NEWS: Update.
1764 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1765 and Paul Eggert <eggert@cs.ucla.edu>
1767 * doc/autoconf.texi (autoheader Invocation): The first argument to
1768 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1769 alternatives and clear up the language a bit.
1771 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1773 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1774 ac_config_guess, ac_config_sub, ac_configure.
1775 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1776 Fix typo that prevented an unnecessary space from being removed.
1777 Problems reported by Ralf Wildenhues in:
1778 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1780 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1782 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1783 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
1784 Don't use the term "thread-safe" to talk about mkdir race
1785 conditions, since the problem is more a process than a thread
1786 issue. Problem reported by Stepan Kasal in:
1787 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
1788 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
1789 the test for 'install' more closely. Look at MKDIR_P first.
1790 Look in the PATH, and at /opt/sfw/bin.
1791 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1792 Don't bother to try mkdir -p, since we already check mkdir --version;
1793 just look at the version number. (There's no easy way to check
1794 for race-free implementations.)
1795 * tests/tools.at (autoconf: subdirectories): Adjust to above
1796 changes, since MKDIR_P now might end in "/mkdir -p".
1798 * doc/autoconf.texi (autoheader Invocation): Mention that the
1799 first arg of AC_DEFINE_UNQUOTED must be a literal.
1800 Problem reported by Ben Pfaff in
1801 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1803 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1804 * doc/autoconf.texi (Special Chars in Variables): New section.
1805 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1806 (Installation Directory Variables): Quote $(datadir) better.
1807 (Limitations of Builtins): Describe some of eval's trickiness.
1809 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1810 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1811 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1812 in front of every arg, not just trailing args. Quote apostrophes.
1813 (_AC_EVAL_ECHO): New macro.
1814 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1815 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1816 removed.
1817 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1818 exposed by quoting of eval argument. Put the command on line line
1819 so it logs better.
1820 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1821 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1822 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1823 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1824 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1825 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1826 Use eval more safely.
1827 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1828 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1829 to be replaced.
1830 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1831 lines, exposed by quoting of eval argument.
1833 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1834 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1836 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1837 initialization of `ac_cv_exeext', do not override it if it was
1838 already set, unless it was set to `no', for compatibility with
1839 Autoconf-2.13, and comment this.
1840 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1841 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1842 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1843 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1844 Document that this test may be overridden by setting
1845 `ac_cv_exeext'.
1847 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1849 Revert these two patches:
1851 2006-04-06 Eric Blake <ebb9@byu.net>
1852 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1853 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1854 2006-04-01.
1856 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1857 Clean up _AC_COMPILER_EXEEXT* macros.
1858 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1859 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1860 ac_file to the name of the default output file and call
1861 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1862 initial `rm' of the candidate files...
1863 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1864 the same list in subsequent `rm' calls, and for the temporary
1865 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1866 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1867 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1868 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1869 no longer needed) by libtool. Make it a cache check.
1870 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1871 copied here by mistake.
1872 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1873 _AC_COMPILER_EXEEXT.
1874 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1875 _AC_COMPILER_OBJEXT directly.
1876 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1878 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1880 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1881 Fix description of how the buggy `sed' works.
1883 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1885 Sync from Automake:
1887 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1888 ENOLCK. Only mention `make -j' when applicable. Only raise
1889 fatal errors when `make -j' is involved. Improve error message.
1891 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1893 * doc/autoconf.texi (Here-Documents): We now know more about
1894 the variable expansion in here documents bug.
1895 Thanks to Tim Rice and Stepan Kasal.
1897 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1898 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1900 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1902 * tests/autotest.at (Multiline command from M4 expansion):
1903 No failure to be expected if the shell quotes newlines in
1904 commands in the `set -x' output. Report by Tim Rice.
1905 * THANKS: Update.
1907 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1909 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1910 expansion in the here-documents used by config.status, as that
1911 runs afoul of the Korn shell version M-12/28/93d bug described in
1912 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1913 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1914 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1916 2006-05-23 Jim Meyering <jim@meyering.net>
1918 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1919 Fix typo introduced with 2006-04-02 change. It reversed the sense
1920 of the test.
1922 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1924 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1925 ac_dB slightly, to save bytes in the script.
1926 Max out at 50 lines, rather than 96; this is more likely
1927 (though not guaranteed) to avoid obscure 'sed' failures.
1929 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1931 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
1932 `tr -d -' as bad option argument. Work around this by deleting
1933 an unrelated character.
1934 Report by Tim Rice <tim@multitalents.net>.
1936 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
1937 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1938 Stepan Kasal <kasal@ucw.cz>
1940 * doc/autoconf.texi (Particular Programs): Do not promise that
1941 we always prefer the GNU version of the program, and that we
1942 search according to PATH; both rules can have exceptions.
1943 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
1944 AC_PROG_SED. Move descriptions of limitations
1945 to the Limitations of Usual Tools section.
1946 (Limitations of Usual Tools) <sed>: Mention script length
1947 limitations with Solaris /usr/ucb/sed.
1948 <grep>: Fix wording for empty alternative. Mention that -c and
1949 -l should not be combined, and that -E and -F should not be
1950 combined.
1952 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1953 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1955 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
1956 limits in Solaris 8 /usr/ucb/sed by testing a long script.
1958 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1960 * doc/autoconf.texi (Defining Symbols): Literal parameter of
1961 AC_DEFINE is now passed to m4_pattern_allow.
1962 * NEWS: Mention that; likewise for AC_SUBST.
1963 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
1964 the parameter to m4_pattern_allow.
1965 * tests/tools.at: Add a check for that.
1967 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1969 * lib/autoconf/status.m4: Fix typos.
1971 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1973 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1974 only the files that this macro generates.
1976 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1978 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1979 the HP-UX sed limitation of 99 commands, labels do not count.
1980 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1981 in the comment.
1982 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1984 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1986 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1987 Import the following fix from coreutils:
1989 2006-01-13 Jim Meyering <jim@meyering.net>
1991 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1992 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1993 not double-quote uses of that variable, to accommodate the rare
1994 case in which getmntent is available in none of the libraries
1995 checked. This happens at least on FreeBSD 5.0.
1997 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1999 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2000 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2001 some other programs unwisely rely on these undocumented vars.
2002 But put in warning comments about them.
2003 Problem reported by Ralf Wildenhues in
2004 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2005 * NEWS: Document that these variables are intended to go away.
2007 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2009 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2010 and set the language to C++ (analogous to the equivalent Fortran
2011 tests).
2013 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2014 * doc/autoconf.texi (C++ Compiler): Document it.
2015 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2016 * NEWS: Update.
2018 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2020 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2021 that caused config.status to generate 100-command sed scripts; the
2022 portable limit is 99.
2024 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2026 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2027 variable `ac_d' instead of `d' to avoid infringing namespace.
2028 Report by Ralf Menzel.
2030 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2032 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2033 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2034 * tests/tools.at (autoconf: subdirectories): New test, taken from
2035 the corresponding problem report by Ralf Wildenhues in:
2036 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2038 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2039 Quote some uses of shell variables if they might suffer unexpected
2040 globbing. This doesn't fix all instances of quoting problems that
2041 I found, just the easy ones that look safe.
2042 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2043 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2044 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2045 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2046 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2047 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2048 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2049 Likewise.
2050 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2051 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2053 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2055 * bin/autoreconf.in ($help): Reword according to the manual.
2056 Suggested by Olly Betts.
2058 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2059 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2061 * bin/autoreconf.in: Pass the directory argument to
2062 `require_configure_ac'. Fix comment.
2063 * tests/torture.at (Configuring subdirectories): Expose this.
2064 Reported by Olly Betts.
2066 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2068 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2069 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2070 Automake as follows:
2072 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2073 `$configure_in' instead of `configure.in', to preserve
2074 directory component.
2076 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2078 * config/config.guess, config/config.sub, config/texinfo.tex,
2079 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2081 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2083 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2084 test for C99 conformance; (bool) 0.5 is an integer constant
2085 expression, but (bool) -0.5 is not. Problem reported by Fedor
2086 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2088 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2090 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2091 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2092 Warn about obsolete install-sh files. Remove stray sentence
2093 fragment and fix cross reference.
2094 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2095 install -d; this undoes the 2006-05-10 change.
2096 (MKDIR_P): Mark with AN_MAKEVAR.
2097 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2098 that we don't require $INSTALL to be thread-safe. Move comments
2099 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2100 of AC_PROG_INSTALL. Output a message saying that we're checking
2101 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2102 MKDIR_P instead of AC_SUBST.
2103 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2104 Special magic for MKDIR_P, too.
2105 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2106 a dnl.
2107 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2109 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2111 Sync from Automake, as follows:
2113 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2114 * config/install-sh: Initialize IFS, so field splitting isn't
2115 turned off later.
2116 * config/mkinstalldirs: Likewise.
2117 * config/missing: Remove superfluous quotes. Replace all uses of
2118 `[' by `test', for consistency, and for..
2119 * config/missing (sed_minuso, sed_output): New variables.
2120 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2121 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2122 Fixes `missing' to detect `--output' for help2man. Fixes
2123 PR automake/483. Report by Dennis J. Linse.
2124 (autom4te): Document in `missing --help'.
2126 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2128 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2129 * config/install-sh: Don't use 'path' to talk about file names,
2130 as per GNU coding standards. Close a race condition reported by Ralf
2131 Wildenhues and Stepan Kasal. There is still a race condition
2132 on hosts that predate Posix 1003.1-1992, but we can't help this.
2133 Don't mishandle weird characters like space on pre-Posix hosts.
2134 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2135 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2136 AC_PROG_MKDIR_P from AS_MKDIR_P.
2137 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2138 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2139 earlier editions are not (including Automake 1.8.3).
2140 Do not suggest mkinstalldirs for thread-safety.
2141 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2142 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2143 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2144 presence of special characters and race conditions.
2145 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2146 in Autoconf's name space.
2148 2006-05-10 Bruno Haible <bruno@clisp.org>
2149 and Paul Eggert <eggert@cs.ucla.edu>
2151 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2152 from Automake with minor changes.
2153 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2155 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2157 * config/install-sh: Update to Automake CVS version, as follows:
2158 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2159 * lib/install-sh: Simplify the expr implementation of dirname.
2160 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2161 * lib/install-sh: Handle --, and diagnose unknown options.
2163 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2165 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2166 `./autom4te' to create `./testsuite', since the `all' target
2167 will ensure its presence, but `installcheck' should not create
2168 the uninstalled wrappers.
2170 * tests/torture.at (Unusual Automake input files): Skip if we
2171 detect automake < 1.8.
2173 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2175 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2176 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2177 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2178 * NEWS: Update.
2180 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2182 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2183 munge (multiple) white space and other oddities.
2184 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2185 single quotes in variable assignment.
2186 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2187 and similar failures by adding multiple spaces, tabs, and other
2188 special characters.
2189 Report and different test suggested by Francesco Romani
2190 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2192 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2193 single quotes, we only need to search for single quotes; this
2194 both simplifies the search pattern, and makes us less
2195 susceptible to `echo' variations for arguments not containing
2196 single quotes.
2197 (_AC_ARG_VAR_VALIDATE): Likewise.
2199 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2201 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2202 `$*' and IFS concatenation issue with traditional shells and
2203 bash-2.04. Report by Seanster@Seanster.com.
2205 2006-05-03 Bruno Haible <bruno@clisp.org>
2207 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2208 precisely which Mac OS X versions have the od problem.
2210 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2212 * doc/autoconf.texi: Use @option systematically.
2214 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2215 and Bruno Haible <bruno@clisp.org>
2217 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2218 about 'od'.
2219 (Integer Overflow): Mention the special case of integer division
2220 overflow.
2222 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2224 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2225 traditional shells like the Solaris one that do not use the
2226 first IFS character for assembling `$*'.
2227 Prompted by a related report from autoconf_bug@nro.ca.
2229 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2230 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2232 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2233 Mention more problems with the -e option.
2235 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2237 * NEWS: Typo.
2238 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2240 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2241 in URLs to improve DVI formatted output (requires texinfo 4.6).
2242 (System Services, Systemology, Shellology): Likewise.
2243 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2244 output.
2246 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2247 continuous text.
2248 (Runtime): Fix macro argument names to match description:
2249 `action-if-found' -> `action-if-true' and similarly.
2250 (Obsolete Macros): Likewise.
2251 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2252 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2253 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2255 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2257 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2259 * ChangeLog: Typo.
2260 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2261 DVI output.
2263 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2265 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
2266 /bin/sh set unsorted output.
2267 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
2268 * tests/local.at: Likewise.
2270 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2272 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2273 (Integer Overflow, Null Pointers, Buffer Overruns):
2274 (Floating Point Portability, Exiting Portably): New sections.
2275 (Writing Test Programs): Fix some langauge. Recommend exiting
2276 with status 1, not merely nonzero. Clarify exit declaration.
2277 (Run Time): Move C exit status stuff to new Exiting Portably section.
2278 (Systemology): Mention Posix and levenez. Update v7 reference.
2279 (Portable Shell): Mention the Posix shell.
2281 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2283 * bin/autoconf.as (me): Replace by as_me.
2285 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2287 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2288 since as_me isn't set yet.
2290 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2292 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2293 a few minor bugs in this area.
2295 * doc/autoconf.texi (Programming in M4sh): Comment out the
2296 documentation of AS_BASENAME, for now.
2297 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2298 (Limitations of Builtins) <basename>: Do not refer to
2299 AS_BASENAME.
2300 * bin/autoconf.as (me): Don't use AS_BASENAME.
2301 (dir): Remove the unused variable.
2302 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2303 AS_DETECT_REQUIRED. All uses changed.
2304 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
2305 All uses changed.
2306 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
2307 (AS_BASENAME): Use "basename --" to protect against leading "-".
2308 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2309 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2310 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2311 (_AS_DIRNAME_PREPARE): Likewise.

2313 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2314 (AS_DIRNAME): Use "dirname --".
2316 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2318 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2319 of "run time" and "run-time" changed to "runtime", for consistency.
2320 * lib/autoconf/fortran.m4: Likewise (in comment).
2321 * lib/autoconf/functions.m4: Likewise.
2322 * lib/autoconf/general.m4: Likewise.
2323 * lib/autoconf/headers.m4: Likewise.
2325 * doc/autoconf.texi (Run Time): Document the exit status situation
2326 with more accuracy and detail.
2328 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2330 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2331 Archive is not officially `GNU' any more. Update URL.
2332 (Defining Directories): Likewise
2333 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2335 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2337 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2338 newline from the `trap' code to finish `config.log'; the NetBSD
2339 /bin/sh resets the exit status after an empty command, as
2340 documented in doc/autoconf.texi.
2341 Reported by Dalibor Topic <robilad@kaffe.org>.
2343 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2345 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2346 Suggested by Bruno Haible.
2348 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2350 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2351 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2352 Instead, just list the shells that we know work.
2353 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2354 changed. Be more cautious about the _cv_ variable.
2355 * tests/tools.at (Syntax of the shell scripts): Check the
2356 _cv_ variable once, at first, to avoid an internal autoconf error
2357 when sh -n does not work.
2359 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2361 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2363 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2365 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2366 use ">&-" since we're only 99.999% sure that this is portable,
2367 and since the MinGW bug is fixed in a different way.
2368 * lib/autotest/general.m4 (AT_INIT): Likewise.
2370 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2372 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2373 before opening config.log, to avoid hitting a bug on MinGW.
2375 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2377 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2378 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2379 This works around a MinGW bug reported by Eric Paire.
2380 Make sure that all writes to the log file append to it,
2381 rather than possibly losing data.
2382 * lib/autotest/general.m4 (AT_INIT): Likewise.
2384 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2386 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2387 description.
2389 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2391 * NEWS: Update.
2393 * configure.ac (AC_INIT): Bump to 2.59d.
2395 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2397 Version 2.59c.
2399 * Makefile.maint (news-date-check): Do not require a leading `*'
2400 before the release date in NEWS.
2402 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2403 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2405 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2406 the instantiated file do not contain the string 'datarootdir'
2407 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2408 @mandir@, replace the reference '${datarootdir}' by the value.
2409 * tests/torture.at (datarootdir workaround): New test.
2410 * NEWS: Advertise this temporary fixup.
2411 Based on a patch by Bruno Haible, reported and analyzed by
2412 Paul Eggert and Noah Misch.
2414 2006-04-12 Eric Blake <ebb9@byu.net>
2416 * tests/autotest.at (Debugging a failed test): Fix comment.
2418 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2420 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2421 all the changes since 2006-04-07.
2423 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2425 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2426 succeeded, but `ln -s file dir' failed, take care to remove the
2427 leftover target before the next test, to prevent its spurious
2428 failure; also make sure `ln file dir' works before selecting it.
2429 Thanks to Keith Marshall for pointing this out.
2430 * THANKS: Update.
2432 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2433 assignments in `at_debug_args', so that we put them correctly
2434 in the `run' script.
2435 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2436 Reported by Eric Blake.
2438 2006-04-11 Eric Blake <ebb9@byu.net>
2440 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2441 top-level tests after micro-suite has been run. Used in...
2442 (Debugging a successful test, Debugging script and environment),
2443 (Debugging a failed test): ...these new tests. The first of these
2444 is fixed by...
2445 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2446 macro, split out from...
2447 (AT_INIT): ...here, so that using -d also generates a run script.
2448 Document that -d inhibits top-level logging.
2449 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2450 inhibits top-level logging; debug scripts are created.
2452 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2453 check.
2454 * tests/autotest.at (Empty test, Empty check): New test to check it.
2456 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2457 from gcc.
2459 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2461 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2462 the files if a problem appears. Make the empty *.at files
2463 read-only, too. Proposed by Ralf Wildenhues.
2465 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2467 * config/Makefile.am: Add comment to force updated Makefile.in.
2469 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2470 space only patch to this file, this patch causes the Makefile.in
2471 files that include freeze.mk to be updated, and thus have a
2472 newer time stamp again, which in turn makes a pristine CVS
2473 checkout have correct time stamps.
2475 * Makefile.maint (cvs-sv): New macro, to be used..
2476 (config.guess-url_prefix, config.sub-url_prefix)
2477 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2478 point to CVS text checkout of Gnulib files.
2479 (copyright-check): Bump current year.
2480 (announcement): Do not hard-wire `./announce-gen'.
2481 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2482 correctly.
2483 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2484 `chmod +x'.
2485 (wget_files): Update config.guess, config.sub, texinfo.tex by
2486 `wget-update', now that their URLs work again.
2488 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2490 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2491 Problem noted by Paul D. Smith.
2493 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2495 * doc/autoconf.texi: Remove unused words from word list.
2496 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2497 .x-sc_trailing_space: New files.
2499 * doc/standards.texi: Sync from gnulib.
2501 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2502 `LIBOBJDIR' as experimental.
2504 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2505 with a target directory; it's internally implemented as `cp'
2506 anyway, but since Autoconf advertises the possibility to use
2507 a target directory when LN_S is `ln -s', we need to find out.
2508 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2509 analyzed by Keith Marshall <keith.marshall@total.com>.
2511 * THANKS: Update.
2513 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2515 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2516 confdefs.h as-is. In general, if it has backslash-newline or the
2517 like, then it doesn't work either to sort or to remove empty
2518 lines.
2520 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2522 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2524 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2526 * lib/autom4te.in (Automake-preselections): Preselect
2527 _AM_SUBST_NOTMAKE.
2529 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2531 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2532 apostrophe within a single-quoted string, as this is the usual
2533 tradition and is easier to read than '"'"'. Don't rely on the
2534 shell treating "$/" like '$/'. Use a more-consistent indenting
2535 style for the trap.
2537 2006-04-09 Eric Blake <ebb9@byu.net>
2539 * tests/autotest.at (Backquote command substitution),
2540 (Multiline backquote command substitution): Remove mistaken
2541 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2542 applied...
2543 (Parenthetical command substitution, Multiline parenthetical
2544 command substitution): here.
2546 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2548 Import macros from gnulib (often changing their name).
2550 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
2551 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
2552 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

2562 (Pointers): Add Gnulib URL.
2563 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
2564 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
2565 Gnulib section.
2566 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
2567 suggest a #define rather than a typedef for _Bool, and mention
2568 Gnulib rather than trying to substitute stdbool code.
2569 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
2570 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
2571 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
2572 AC_STRUCT_DIRENT_D_TYPE.
2573 (Particular Types): Mention stdint.h and inttypes.h as standard
2574 headers too.
2575 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
2576 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2577 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2578 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2579 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2580 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2581 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2582 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2583 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2584 (Coding Style). Don't mention m4_expand_once.
2585 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
2586 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
2587 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
2588 (AC_CHECK_FUNCS): Use it.
2589 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
2590 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
2591 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
2592 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
2593 (AC_HEADER_ASSERT): New macro.
2594 (AC_HEADER_STDBOOL): Don't assume "#error" works.
2595 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
2596 Catch a bug in an HP-UX C compiler.
2597 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
2598 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
2599 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

2602 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
2603 New macros.
2605 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
2606 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
2608 2006-04-08 Stepan Kasal <kasal@ucw.cz>
2610 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
2611 of the warning introduced by the 2001-08-28 change.
2613 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
2614 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2616 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
2617 variables shall be overriden by the cache.
2618 * tests/torture.at (AC_ARG_VAR): Test also with a first value
2619 that contains braces.
2621 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2623 Revert the patch from 2006-04-01 and only improve
2624 _AS_DETECT_BETTER_SHELL:
2626 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2627 skip nonexistent directories.
2628 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2629 only shell candidates which exist.
2630 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2631 * lib/autotest/general.m4 (AT_INIT): No need to give three
2632 parameters to _AS_PATH_WALK.
2634 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2635 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2637 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2638 distinguish m4sugar macros.
2639 * tests/tools.at (autoupdating with aclocal and m4_include):
2640 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2641 test case by Noah Misch <noah@cs.caltech.edu>.
2643 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2645 Revert my change from 2006-03-17, in other words:
2646 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2647 and DUALCASE=1.
2648 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2649 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2650 it is set.
2652 2006-04-07 Eric Blake <ebb9@byu.net>
2654 * doc/autoconf.texi (Programming in M4sh): Document that
2655 AS_MKDIR_P exits the script on failure.
2656 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2658 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2660 * config/elisp-comp, config/install-sh, config/mdate-sh,
2661 config/missing, config/mkinstalldirs: Sync from Automake.
2663 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
2664 from Automake.
2666 * doc/make-stds.texi: Sync from gnulib.
2668 2006-04-06 Eric Blake <ebb9@byu.net>
2670 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2671 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2672 2006-04-01.
2674 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
2675 Eric Blake <ebb9@byu.net>,
2676 Paul Eggert <eggert@cs.ucla.edu>,
2677 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2679 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2680 whether `set' quotes correctly: redirect stderr of the tested
2681 `set', and use a subshell, for Ultrix; use `sed' instead of
2682 `grep' for zsh `set' which may write binary output; match only
2683 at the beginning of a line, to avoid false positives.
2684 In order to avoid false positives by unrelated variables with
2685 multiline content, put the dump algorithm in a subshell and
2686 unset all variables containing newlines (except some which are
2687 special to the shell). Warn about cache variables that are
2688 unset.
2690 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2692 * config/config.guess, config/config.sub, config/texinfo.tex:
2693 Sync from upstream.
2695 * tests/mktests.sh: Reword comments.
2697 * tests/mktests.sh: Only skip internal macros starting with
2698 `_AC_' or `__AC_'. Noted by Stepan Kasal.
2699 Update exclusion lists for the test suite to this end:

2891 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to

2894 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2895 initial `rm' of the candidate files...
2896 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2897 the same list in subsequent `rm' calls, and for the temporary

2900 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2901 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2902 no longer needed) by libtool. Make it a cache check.
2903 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2904 copied here by mistake.

2944 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.

3615 2005-11-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3617 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
3618 ac_clean_files and LIBOBJS.
3620 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3622 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
3623 Factor functionality to..
3624 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
3625 `AC_SUBST($1)' in the public version.
3626 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
3627 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
3628 ac_pt_* variables.
3630 2005-11-01 Stepan Kasal <kasal@ucw.cz>
3632 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
3633 filesystems.
3635 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3637 * NEWS: Move AH_HEADER mention to right place.
3639 2005-10-27 Stepan Kasal <kasal@ucw.cz>
3641 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
3642 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3644 2005-10-25 Stepan Kasal <kasal@ucw.cz>
3646 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
3647 conftst2.$ac_objext.
3648 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3650 2005-10-24 Stepan Kasal <kasal@ucw.cz>
3652 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
3653 conftest.o, to see whether the compiler really obeys; rm the object
3654 file before and after the test and register it with ac_clean_files.
3655 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3657 2005-10-21 Stepan Kasal <kasal@ucw.cz>
3659 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
3660 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
3661 code so that the most common case requires less forks.
3663 2005-10-20 Stepan Kasal <kasal@ucw.cz>
3665 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
3666 not portable; thanks to Paul Eggert and Alexandre.
3668 * NEWS: Fix an old typo.
3670 2005-10-20 Jim Meyering <jim@meyering.net>
3672 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
3673 the latter'', in two places.
3675 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
3677 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
3678 AC_LANG_PROGRAM, fixing a typo. Don't give details about
3679 the inner workings of AC_LANG_FUNC_LINK_TRY.
3680 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
3681 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
3682 by the function rather than ignoring it.
3683 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
3684 comparing its address. Intel's interprocedural optimization was
3685 outsmarting the old heuristic. Problem reported by
3686 Mikulas Patocka.
3688 2005-10-19 Stepan Kasal <kasal@ucw.cz>
3690 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
3692 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
3694 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

3697 2005-10-04 Stepan Kasal <kasal@ucw.cz>
3699 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
3700 before removing it (chmod -R u+rwx); there are three instances of this.
3702 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3703 Stepan Kasal <kasal@ucw.cz>
3705 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3706 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3707 make its content writable before removing it. Remove an errorneous
3708 comment from the end, where the logs of the failed tests are copied
3709 to the main log file.
3711 2005-09-27 Stepan Kasal <kasal@ucw.cz>
3713 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
3714 in case the computer is too quick. Double quote the configure.ac
3715 snippets.
3717 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
3718 problems if the testsuite were running too fast.
3720 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3722 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3723 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3724 (which belong to Xt, not X itself). See Debian bug 327655.
3725 * NEWS: Mention this.
3727 2005-09-07 Stepan Kasal <kasal@ucw.cz>
3729 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
3731 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
3733 * config/move-if-change: Don't output "$2 is unchanged";
3734 suggested by Ben Elliston. Handle weird characters correctly.
3736 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3738 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3739 calls, so that the final expansion of this macro is shorter.
3740 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3741 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3742 the cleanup there. Use AS_VAR_* macros, to be more general.
3743 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3745 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3747 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
3749 2005-09-01 Stepan Kasal <kasal@ucw.cz>
3751 * doc/autoconf.texi (Configuration Headers): Add an index entry
3752 for AH_HEADER.
3754 2005-08-26 Pavel Roskin <proski@gnu.org>
3756 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
3757 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
3758 running xmkmf.
3760 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
3762 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3763 The previous patch didn't work, so try a better one.
3765 2005-08-26 Stepan Kasal <kasal@ucw.cz>
3767 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3768 in the example. Reported by Bruno Haible.
3769 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3770 "if $undefined_var;" succeeds with my shell.
3772 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
3773 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
3774 but change the m4_divert_text to m4_divert_once.
3776 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
3778 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3779 Work around bug in Solaris /usr/xpg4/bin/awk.
3780 The bug is present in at least Solaris 8 through 10.
3782 2005-08-24 Stepan Kasal <kasal@ucw.cz>
3784 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
3785 some evil values and relying on the fact that $* concatenates the
3786 parameters by the first character from IFS.
3788 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3789 Stepan Kasal <kasal@ucw.cz>
3791 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
3792 first header appears, define AH_HEADER.
3793 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
3794 Update limitations about when to call AC_CONFIG_HEADERS.
3795 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3796 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3797 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3798 ``Configuration Actions''; fix their index entries.
3800 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3801 options correctly. Process N-M as M-N if M is smaller than N.
3802 Process ranges correctly so that N-N will run only N.
3803 Sort and uniquify the tests that will be run. If there is more
3804 than one test, reinsert the banners for the tests.
3805 * tests/autotest.at (Keywords): Unmark XFAIL.
3807 2005-08-23 Stepan Kasal <kasal@ucw.cz>
3809 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
3810 before passing the macro name to AH_TEMPLATE.
3812 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3813 now opens log after option processing; in particular, --version
3814 and --help do not touch config.log.
3816 * Makefile.maint: Revert the change from 2005-08-12.
3818 2005-08-22 Stepan Kasal <kasal@ucw.cz>
3820 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
3821 common code to...
3822 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
3824 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3826 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
3827 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
3828 Language cleanup.
3830 * doc/autoconf.texi (Defining Symbols, Changed Results):
3831 Prepend to LIBS, not append, in examples.
3833 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3835 When building in place, set srcdir="."; suggested by Tim Van Holder.
3837 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3838 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3839 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3840 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
3841 does not mean "no --srcdir option".
3843 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3845 * tests/autoscan.at (autoscan): New file.
3846 * tests/suite.at: Use it.
3847 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
3848 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
3850 * tests/autotest.at (Keywords): Test keywords combinations.
3852 2005-08-12 Stepan Kasal <kasal@ucw.cz>
3854 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
3855 add "2>&1"; gzip 1.2.4 prints help on stderr.
3857 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3859 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
3860 was pushdef'ed twice while popped only once. Push it only once.
3861 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
3863 2005-07-26 Stepan Kasal <kasal@ucw.cz>
3865 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
3866 prefixed by mere "===", not "configure: === ".

3870 * Makefile.maint: Update from Bison.
3872 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3873 "<tab>" in comment, so that the point is understandable.
3875 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3877 Rewrite substantial part of lib/autoconf/status.m4.
3878 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3879 and CONFIG_COMMANDS are not processed in four separate loops.
3880 Instead, there is one main loop. This alows that the common code
3881 is expanded only once, thus config.status (and configure) is smaller.
3883 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3884 the AC_LIST_FILES and cousins macros are no longer used.
3886 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3887 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3888 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3889 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3890 contain the initialization, nor the for loop, nor the associated
3891 commands; all these go to ...
3892 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3893 _AC_OUTPUT_CONFIG_STATUS.
3894 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3895 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3896 (_AC_OUTPUT_FILE): The creation of the sed script ...
3897 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3898 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3899 _AC_OUTPUT_MAIN_LOOP.
3900 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3901 _AC_CONFIG_COMMANDS): Use ...
3902 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3903 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3904 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3905 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3906 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3907 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3908 ... new macros.
3909 (_AC_CONFIG_UNIQUE): Update.
3910 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3911 Replaced by this ...
3912 (_AC_LIST_TAGS): ... new common macro.
3913 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3914 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3915 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3916 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3917 this didn't belong to the `config commands' section.
3918 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3919 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3920 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3921 to the `config commands' section either.
3922 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3923 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3925 ... and many changes to the comments nearby.
3927 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3928 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3929 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3930 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
3931 (#define header templates): The comment at the top of the generated
3932 header now includes the name(s) of the source file(s).
3934 Several unrelated small changes:
3936 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
3937 parameter to AC_DIAGNOSE.
3938 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
3939 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
3940 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
3941 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
3942 with AU::AC_OUTPUT.
3943 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
3944 in AC_OUTPUT doesn't double-quote it either.
3945 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
3946 parameters.
3948 2005-07-10 Stepan Kasal <kasal@ucw.cz>
3950 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
3951 versions of Portland Group compiler produce single- and double-quoted
3952 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
3953 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3955 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3957 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3958 This is a corrected version of yesterday's patch.
3960 2005-07-07 Stepan Kasal <kasal@ucw.cz>
3962 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
3963 path, too; insert a "===" to emphasize the line.
3965 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
3966 ac_cv_build_alias to ac_build_alias.
3967 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3969 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3970 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3971 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3972 (AC_ARG_VAR): ... here.
3973 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3974 target_alias.
3976 Keep a list of all precious variables and process them with one simple
3977 for loop, instead of expanding all commands, or, OTOH, complicated
3978 processing of output of "set".
3979 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3980 variable names in new macro...
3981 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
3982 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
3983 a loop to assign all ac_env_* and ac_cv_env_* variables.
3984 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3985 to INIT_PREPARE.
3986 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3987 its value to shell variable ac_precious_vars and call
3988 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
3989 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
3990 _AC_ARG_VAR_VALIDATE.
3992 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
3993 and the AC_SUBSTs ...
3994 (AC_INIT): ... here.
3996 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
3997 the ac_subst_files section in config.log.
3999 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

4008 Fix problems reported by Nicolas Joly.
4009 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
4010 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4011 They are generated by the Tru64 v5.1B shell.
4013 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4015 Fix my changes from 2005-07-01; reported by Noah Misch.
4016 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4017 description, the macro now accepts only a single tag.
4018 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
4020 Fix cases when the varsions of Autoconf and Autotest don't match.
4021 Reported by Noah Misch.
4022 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4023 at_top_builddir, for compatibility with older autotest.
4024 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4025 is not set, use at_top_builddir, for compatibility with older
4026 versions of autoconf.
4028 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4030 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4031 Problem reported by Patrick Welche.
4033 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4035 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4036 sed substitution command, so that we allow | in program prefixes
4037 and program suffixes. (& is a problem anyway; we're not fixing
4038 that here.)
4039 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4040 configure_input, top_builddir, srcdir, etc.
4041 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4042 PATH_SEPARATOR in AUTOTEST_PATH.
4044 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4046 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4047 for loop over config.site files using `set', to allow
4048 directory names containing IFS characters.
4050 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
4052 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4053 directories with weird names. Apparently some people like living
4054 on the edge. However, improve the test that "pwd" actually does
4055 report a name for the working directory.
4056 * NEWS: Remove the claim that we test for funny chars in dir names.
4058 2005-07-01 Stepan Kasal <kasal@ucw.cz>
4060 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
4061 replaced ...

4074 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4075 document to output the default config_* lists to config.status.
4076 Don't recognize option --file, if the functionality is not there.
4077 Likewise for --header; moreover, recognize --he and --h as shortcuts
4078 for --help in that case.
4080 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4081 matches the order of execution. No code changed.

4104 (AC_SUBST): Call it.
4105 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4106 the directory specific variables; but don't call it for configure_input.
4108 2005-06-28 Derek Price <derek@ximbiot.com>
4110 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4111 addition.
4113 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4115 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4116 directory have inherent problems with special characters like spaces,
4117 due to limitations in Make syntax. Problem reported by Alexandre
4118 Duret-Lutz.
4119 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

4132 from Justace Clutter.
4133 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4134 variable into diagnostic. Make the diagnostic an error, not a warning,
4135 because we really don't support spaces and suchlike in dir names.
4136 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4137 Don't worry about backslashes in srcdir; it can't happen now.
4138 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
4139 Simplify ac_optarg handling.

4164 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4165 b, t, r, w commands require single space, while : cannot have any.
4166 (Special Shell Variables): Fix sed code this in the example.
4167 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4168 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4170 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4171 expand to the empty list. Don't use two pairs of m4_changequote,
4172 it's not necessary.
4174 2005-06-20 Derek Price <derek@ximbiot.com>
4176 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4178 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4180 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4181 * doc/autoconf.texi:
4182 Don't mention Solaris versions so much, if a
4183 problem is common to all extant versions of Solaris. Say "SunOS
4184 4" instead of "SunOS" for SunOS 4.
4185 (awk): Mention more of the limitations of traditional Awk.
4186 (cat): Don't talk about cat -v.
4188 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
4190 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.

4193 to be compatible with glibc strverscmp.
4194 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4196 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4197 on Mac OS X 10.4 reported by Peter O'Gorman in:

4199 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
4200 Use shell builtins rather than 'expr', to work around expr bug.
4202 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4204 * doc/autoconf.texi: "filesystem" -> "file system".
4205 "behaviour" -> "behavior".

4207 * lib/autoconf/general.m4: Omit blank after ":" sed command,
4208 as per POSIX.
4209 * lib/m4sugar/m4sh.m4: Likewise.
4210 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
4211 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4213 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4214 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4215 to update the man page. That way, we don't have to check in new

4218 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4219 quotes and backslashes. Patch from Derek Price.

4224 AS_TR_SH.
4226 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4228 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4229 -u, since it outputs chatter if the input files are the same.
4230 Problem reported by Ralf Menzel.
4232 2005-06-08 Derek Price <derek@ximbiot.com>
4234 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4235 renaming them since they are about to be redefined anyhow.
4237 2005-06-08 Derek Price <derek@ximbiot.com>
4239 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4240 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4241 Move m4_undefine to alphabetical order.
4243 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4245 * README: Recommend GNU M4 1.4.3 or later.
4246 * doc/autoconf.texi (Introduction): Likewise.
4247 Reword to avoid some formatting glitches.
4248 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4249 Clarify explanation of HP compiler bug.
4250 Redo example output tp match current CVS snapshot.
4251 Use @example.org in email addresses when the examples
4252 might get inadvertently cut-and-pasted into user code.
4253 Remove example of autom4te usage that doesn't seem to work now.
4254 Use modern AC_INIT (except when the example is meant to be
4255 shown with Autoconf 2.13).
4256 Update ksh info for Solaris 9 and later.
4257 KB -> kB.
4258 Modernize description of Automake versions a bit.
4259 Don't claim a future version of Autoconf is near.
4260 * doc/install.texi: Reword to avoid some formatting glitches.
4262 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4264 * doc/autoconf.texi: Add [] to examples, so that the manual
4265 follows its own advice about quoting better.
4266 Reword to avoid some formatting glitches.
4267 * doc/installt.exi: Reword to avoid some formatting glitches.
4269 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4270 Tru64 ksh pattern matching bug. Reported against Libtool by
4271 Albert Chin <libtool@mlists.thewrittenword.com> and
4272 Nicolas Joly <njoly@pasteur.fr>.
4274 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4276 m4_cdr of one-member list was [[]] (one-member list containing an
4277 empty string) instead of [] (an empty list. Callers were skewed to
4278 match this misbehaviour. As a consequence of this:
4279 - m4_foreach([x], [], [foo]) expanded to `foo', while
4280 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4281 This bug has been fixed:
4283 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4284 expand to an empty string; print error msg if called without
4285 an argument list.
4286 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4287 misbehaviour; handle [] and [[]] correctly.
4289 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4291 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

4293 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4295 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4297 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4298 swallow records with more than 99 fields.
4299 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4300 parse the long line.
4302 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4304 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4305 swallow literals longer than 399. Reported by Ralf Wildenhues.
4306 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4307 to workaround this limitation.
4309 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4311 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4312 to gfortran, and make these the first two compiler names
4313 checked (following the general autoconf preference for gcc).
4315 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4317 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4318 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4319 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4321 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4323 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4324 expression of unbounded size when processing the --list
4325 option. This runs afoul of a limit of 399 bytes per regular
4326 expression on AIX. Problem reported by Ralf Wildenhues.
4328 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

4331 * doc/autoconf.texi (Particular Headers): Reword example
4332 for multiline stdbool replacement.
4333 (Setting Output Variables): Reword text a bit. Don't
4334 give all the details about |#_!!_#|.
4335 Reword description of line replacement.
4337 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4339 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4340 now contain newlines, and substituted files must be referenced on
4341 a line alone; the sed scripts to substitute them are now very
4342 different.
4343 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4344 commands can be put in a sed script portably.
4345 * doc/autoconf.texi (Setting Output Variables): Document above
4346 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4347 use of multiline substitution.

4357 * tests/local.at: Don't attempt to check for negated character
4358 classes in shell scripts. The test was too brittle.
4360 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4362 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4363 * doc/autoconf.texi (Limitations of Builtins): Document this
4364 limitation.
4366 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4368 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4369 common code; used in many places in the tree.

4371 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4373 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4375 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4376 messages when ac_unique_file is not found.
4377 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4378 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4379 commands, for consistency with AC_MSG_ERROR and such.
4381 * bin/autoconf.as: Make more use of "shift 2" in option processing.
4383 * bin/Makefile.am: Merge the two rules for creating scripts.

4391 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4393 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4394 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4395 (ac_top_builddir): ... this ...
4396 (ac_top_build_prefix): ... to this; the old name is also kept, for
4397 backward compatibility.
4398 (ac_top_builddir_sub): New variable, without the trailing slash,
4399 always nonempty.
4400 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4401 * doc/autoconf.texi (Configuration Actions): Rename
4402 ac_top_builddir to ac_top_build_prefix.
4403 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

4412 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4414 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4415 argument to m4_foreach. I guess it was necessary in the past,
4416 but I think it's a no-op now.
4418 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4420 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4421 ``cat <<_ACEOF'' commands to one.
4422 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4423 * lib/autoconf/status.m4: On various places, use expr instead of
4424 ``echo|sed.''
4425 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4426 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4427 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4428 a range.
4429 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4430 the wrong patterns between ``case'' and ``esac.'' The previous
4431 code had false positives.
4433 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4435 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4436 as on 2005-05-02.
4437 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
4438 Mention LIBOBJDIR.

4499 * doc/autoconf.texi (Autoconf Language): Be more precise about
4500 quoting rules. Problems noted by Stepan Kasal.
4501 Also, throughout this document, be more careful about white space.
4502 "blank", "white space", and "space" all have different meanings
4503 and we should be careful to say what we mean.
4505 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4507 Fix C++ related problems reported by Werner Lemberg.

4523 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
4524 set by latest automake.
4526 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4528 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
4529 outputs 0 on GNU/Linux these days.
4531 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4533 * doc/autoconf.texi (Autoconf Language): Add more description
4534 about quoting heuristics.
4535 (Limitations of Builtins): Describe "set -" problems.
4537 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4539 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4540 not newline.
4542 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4543 by AC_DEFINE; it was a mistake.
4544 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4546 2005-04-25 Stepan Kasal <kasal@ucw.cz>
4548 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
4550 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4552 * doc/autoconf.texi (External Software): Quadrigraphs are not
4553 processed correctly in AS_HELP_STRING; avoid this in the examples.
4554 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4555 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4556 comment and reduce m4_default([foo], []) to [foo].
4557 (m4_strip): Update the explanation.
4559 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4561 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4562 Remove core.conftest.* too; it's generated by Tru64 5.1.
4563 Problem reported by Jennis Pruett.
4564 * lib/autoconf/functions.m4
4565 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4566 Don't bother to remove core files; AC_RUN_IFELSE should do that
4567 for you.

4609 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
4611 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4613 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4614 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4615 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4616 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4617 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4619 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4621 * NEWS: The configure command now warns you if you attempt to use
4622 a directory whose name contains a special character like space,
4623 newline, or "\".
4624 * doc/autoconf.texi (Installation Directory Variables): Allow
4625 "," in file names. Do not use \@; it's not a portable regexp.
4626 * bin/Makefile.am (edit): Likewise.
4627 * lib/Makefile.am (edit): Likewise.
4628 * tests/Makefile.am (edit): Likewise.
4629 * tests/semantics.at: Likewise.

4636 (AC_INIT): Use it.
4637 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4638 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4639 ac_pwd, and quote srcdir.
4640 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4642 * doc/autoconf.texi: Fix some systematic formatting problems.
4643 ".)" needs a following @: if not at the end of a sentence, and
4644 similarly for "!)". "etc." should be preceded by a comma.
4645 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4647 2005-03-22 Bruno Haible <bruno@clisp.org>
4649 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4650 argument is often called 'build-aux'.
4652 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4654 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4655 macro AC_TRY_LINK is obsolete.
4656 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4657 `AC_CONFIG_FILES'.
4659 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4661 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4662 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4663 from a Common Lisp's `cl'.
4664 (AC_PROG_CXX): Behave according to the documentation: don't
4665 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4666 make the variable CCC precious; use `cl.exe', not `cl'.
4668 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4669 Alexandre Duret-Lutz <adl@gnu.org>
4671 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4672 /dev/null, as "configure" shouldn't read stdin, and this insulates
4673 us from problems (e.g., when testing for "cl"). Also, do this
4674 redirection before invoking "hostname" or "uname", and keep the
4675 original input stream available via...
4676 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4677 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4678 bother with "</dev/null" since it's now done at the top of
4679 'configure'.
4680 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4681 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

4685 * tests/base.at (Input/Output): New test.
4687 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4689 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4690 newline if neither \c nor -n work, as that would output two
4691 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4693 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4695 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4696 This causes that any required macros inside will get before the if.
4697 * doc/autoconf.texi (autom4te.cache): A typo.
4699 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4701 Undo previous change, except keep the change to
4702 lib/autoconf/programs.m4 that replaced grep with shell
4703 pattern-matching. This is because net-snmp configure reads stdin.
4704 Reported by Noah Misch.
4706 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4708 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4709 from /dev/null, as "configure" shouldn't read stdin, and this
4710 insulates us from problems (e.g., when testing for "cl").
4711 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4712 before invoking "hostname" or "uname".
4713 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4714 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4715 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4716 "</dev/null" since it's now done at the top of 'configure'.
4717 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4718 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4719 Also, replace grep with shell pattern-matching, to save a process.
4721 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4723 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4724 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4725 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4726 compiler.
4728 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4730 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4731 grep -q isn't portable. Improve grep -s explanation.
4732 Problem reported by Dan Manthey.
4734 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4736 * doc/autoconf.texi (Special Shell Variables): Clarify
4737 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4739 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4741 * doc/autoconf.texi: Use @acronym for DJGPP.
4742 Fix some @code's that should have been @env's, and vice versa.
4743 Sort environment variable names.
4744 Mention that shells no longer inherit IFS.
4745 Don't recommend PATH_SEPARATOR=';' so strongly.
4746 Mention that $RANDOM might expand to the empty string.
4747 "symlink" and "soft link" -> "symbolic link".
4748 Improve mktemp description (reported by Bruno Haible).
4750 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
4752 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
4753 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
4754 Likewise.
4755 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
4756 Likewise.
4758 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
4760 * NEWS: Mention AT_COPYRIGHT.
4762 * tests/local.at (AT_CMP): Use diff directly on input files rather
4763 than copying them.
4765 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
4766 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
4768 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4769 and Paul Eggert <eggert@cs.ucla.edu>
4771 * tests/autotest.at (Empty test suite): New test.

4773 (Substitute a 2000-byte string, Define to a 2000-byte string)
4774 (Substitute a newline, Define a newline): New tests.
4776 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4778 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
4779 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
4780 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
4781 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
4782 (Standard regular expressions): New test.
4783 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
4784 excess test name quoting.
4785 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
4786 CPPFLAGS to `configure' instead of setting it in `configure'.
4788 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
4789 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
4790 on some platforms.
4792 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
4793 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
4795 * tests/local.at (AT_CMP): New macro.
4796 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

4800 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
4801 * tests/c.at (Extensions): Do not exit early.

4821 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
4823 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
4824 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4826 Try not to generated lines of unlimited length, as POSIX places a
4827 2047-byte limit on line length of portable text files.
4828 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
4829 Use newline as a separator, not space.
4830 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
4831 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
4832 space.
4834 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4836 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
4837 as_func_*. Add test to check whether positional parameters
4838 are restored after function return.
4840 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
4842 * doc/autoconf.texi (Special Shell Variables): Mention _,
4843 BIN_SH, DUALCASE. Say that variables other than "status" are safe
4844 if they contain a lower-case letter. The DUALCASE problem was
4845 reported by Ralf Wildenhues.
4847 * bin/autoconf.as: Don't exit with status 0 after write failure
4848 with --help or --version.
4849 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
4850 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.

4854 * doc/autoconf.texi (Limitations of Usual Tools):
4855 Unicos 9 sed limitations.
4856 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
4857 to get the option-enhanced interface on older Crays. Try ftn for
4858 Fortran 95 (newer Crays).
4860 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
4862 * man/Makefile.am (.x.1): Go back to the simple solution, but take
4863 care to echo the commands, so the user knows what's going on.
4864 Modified from a suggestion by Stepan Kasal.
4866 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
4867 with a cross reference. Derived from a suggestion by Bruce Korb.
4869 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
4871 * doc/autoconf.texi (config.status Invocation): Warn about
4872 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
4873 * doc/install.texi (Defining Variables): Likewise.
4874 Based on a proposed patch by Ralf Wildenhues.
4876 * man/Makefile.am (.x.1): Make sure the required generated files
4877 are up to date. Problem and original solution proposed by Stepan Kasal.
4878 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
4879 implicit-man-prerequisites): New rules, used by the above.

4885 2005-01-29 Stepan Kasal <kasal@ucw.cz>
4887 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4888 Update the long comment explaining it.
4890 m4_require no longer writes an ``is required by'' line to the
4891 execution stack. It contains only one bit of non-redundant
4892 information: that the macro was required, not called. And even
4893 this bit is useless in most situations: have you ever met a macro
4894 which both calls and requires the same macro?
4896 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4897 (_m4_defun_pro_outer): ... only via this macro, for the outermost
4898 macro.
4899 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
4900 (m4_expansion_stack_pop): Remove the misplaced comment.
4901 (m4_require): Don't put the ``is required by'' line to the
4902 execution stack; slightly improve the out-of-a-defun error message.
4903 (_m4_divert_grow): New macro, counter for the temporary diversions.
4904 (_m4_require_call): Use it.
4905 * tests/m4sugar.at (m4_require): Expect output without the
4906 ``is required by'' messages.
4908 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4910 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4911 rather than x for expr.
4913 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
4914 this is safe.
4915 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
4916 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

4925 * doc/make-stds.texi, doc/standards.texi: Update from masters.
4926 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
4927 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
4928 from masters, so that FileUtils.pm's update_file provide --force
4929 support.
4930 * bin/autoheader.in: Pass $force to update_file so that
4931 config.h.in is always recreated when --force.
4933 2005-01-24 Stepan Kasal <kasal@ucw.cz>
4935 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
4937 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
4939 * doc/autoconf.texi (Limitations of Builtins): Clarify that
4940 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
4942 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
4944 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
4945 Warn about newline stripping in `` and $(). Update Solaris
4946 version to 9.
4947 (Limitations of Builtins): Use expr "X...", not expr "x...", as
4948 X insulates us from future changes to Posix.
4949 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
4950 stripping.
4952 2005-01-19 Stepan Kasal <kasal@ucw.cz>
4954 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
4955 you cannot use AC_DEFINE to define macros containing `[' or `]'.
4957 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
4959 * doc/autoconf.texi (Limitations of Usual Tools): Document bug

5316 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5317 "char c = '\200';" rather than "char c = 0x80;" as the

5427 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
5428 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
5429 in test makefile.
5430 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
5431 readable; it's not true in OS/2-emx.
5433 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
5435 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5436 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5437 (trivial change). Problem and patch reported by Andrew Church in:
5438 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5440 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
5442 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

5444 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
5445 Also, fix some minor spacing and punctuation bugs.
5447 2004-09-02 Akim Demaille <akim@epita.fr>
5449 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
5450 "case" to restore ordering.
5451 Reported by Stepan Kasal.
5453 2004-08-26 Akim Demaille <akim@epita.fr>

5467 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5468 texinfo.tex for now (done by hand now).
5469 * Makefile.maint (wget_files, cvs_files):
5470 Remove ansi2knr.c; nobody uses it.
5471 (ansi2knr.c-url_prefix): Remove.
5472 (cvs-update): Fix test for failure. I don't know why it ever
5473 worked...
5475 * doc/autoconf.texi: Update URLs, some of which went stale.
5476 Use @uref rather than @href.
5478 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5479 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5481 * config/config.guess, config/config.sub, config/elisp-comp,
5482 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5483 doc/fdl.texi, doc/standards.texi: Sync with master copy.
5485 * NEWS, TODO, configure.ac, bin/autoscan.in,
5486 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
5487 doc/install.texi, lib/Autom4te/Configure_ac.pm,
5488 lib/Autom4te/FileUtils.pm, lib/autoconf/general.m4,
5489 lib/autoconf/programs.m4, lib/autoconf/status.m4,
5490 lib/autotest/general.m4, lib/m4sugar/m4sh.m4,
5491 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
5492 tests/tools.at, tests/torture.at:
5493 Use "file name" rather than "filename" or "path",
5494 to be consistent with the terminology of the GNU coding standards.
5496 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5498 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5499 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5500 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5501 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5503 More fixes to support spaces in the name of the build directory.
5504 This isn't a complete fix but it's an improvement.
5506 * bin/autoconf.as (autom4te_options): New var.
5507 Use it instead of appending to AUTOM4TE, so that we can allow
5508 spaces in the build directory's absolute name.
5509 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5510 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
5511 AT_CHECK_NOESCAPE): Likewise.
5512 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
5513 main program): Likewise.
5515 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
5517 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
5518 From Ralf Corsepius in:
5519 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
5521 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
5523 * doc/autoconf.texi (Function Portability): Document isinf and
5524 and isnan. From a suggestion by Kevin Ryde.
5526 * lib/Autom4te/General.pm (END): Return correct exit status even
5527 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5529 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5531 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5532 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5533 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5535 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5537 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5538 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5539 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5540 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5541 * lib/autom4te.in (Automake-preselections): Preselect
5542 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5544 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5546 * lib/autom4te.in (Automake-preselections): Preselect
5547 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5548 trace them.
5550 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5552 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5553 Tru64.
5554 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5555 Document problem with "`""`" in pdksh POSIX mode.
5557 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5559 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5560 with pdksh, too. Problem reported by Patrick Welche via
5561 Gary V. Vaughan.
5562 * doc/autoconf.texi (Shellology): Note that set -o posix is
5563 useful for pkdsh, too.
5565 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5567 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5568 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5569 Don't fail if ENV or BASH_ENV is readonly.
5570 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5571 etc. are read only. Problem reported by Ludovic Courtes.
5573 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5575 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5576 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5577 (trivial change)
5579 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5581 * doc/autoconf.texi (File System Conventions): Warn about
5582 names like "aux". Problem reported by Eric Blake.
5584 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5585 by zero instead of array size, so that we can use any arithmetic
5586 constant expression (instead of requiring an integer constant
5587 expression). This allows us to test expressions like DBL_MAX <
5588 LDBL_MAX, which didn't conform to the C standard using the old
5589 method.
5590 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5591 now that we can do floating-point tests at compile time.
5593 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5595 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5596 and LDBL_EPSILON, as the resulting expression isn't an
5597 integer constant expression and violates the C standard.
5598 Problem reported by Nelson H. F. Beebe. Also, check
5599 for "L" suffix, and check that long double doesn't have
5600 worse range or precision than double, that mixed-mode
5601 arithmetic doesn't generate a diagnostic, that double
5602 constants fit in long double.
5604 2004-06-03 Kevin Ryde <user42@zip.com.au>
5606 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5607 malloc(0) and realloc(NULL,size).
5609 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5610 Bob Proulx.
5612 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5614 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5615 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5616 by Jim Meyering.
5618 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5620 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5621 can be rewritten using if-then-else. Suggested by Bruno Haible.
5623 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5625 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5626 Problem reported by Stepan Kasal.
5628 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5630 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5631 change). Patch reported by Ralf Wildenhues in
5632 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5634 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5635 function F exists if the compiler and linker let you compile an
5636 expression like (F != 0). Recent versions of GCC optimize away
5637 the reference to F in that case, since every function address must
5638 be nonzero, so the link succeeds even if F does not exist.
5639 Problem reported by Manu in
5640 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5642 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5643 "Unix". Many uses changed.
5644 (Limitations of Builtins): Explain better why the ! command isn't
5645 portable.
5647 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5649 * lib/autom4te.in (Automake-preselections): Preselect
5650 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5652 2004-05-19 Kevin Ryde <user42@zip.com.au>
5654 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5655 referencing AC_FUNC_STRERROR_R.
5657 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5658 note pessimistic assumption when cross compiling.
5660 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5662 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5663 (until 2004) invoked subcommands with sh -e, contra POSIX.
5664 Reported by Kevin Ryde.
5666 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5668 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5669 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5670 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5671 `test -f " /usr/bin/grep"', which _always_ failed.
5672 (AC_PROG_SED): Ditto bogus PATH fix.
5673 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5674 requires that grep correctly supports _multiple_ `-e' options, rather
5675 than stating only that grep should accept `-e'.
5677 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5679 Port to C99, which requires that 'exit' be declared.
5681 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5682 to ensure that stdlib.h is included.
5683 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5684 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5685 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5686 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5687 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5688 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5689 when using 'exit' in a test; C99 requires that 'exit' be declared.
5691 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5693 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5694 now prefers 'grep' implementations that accept -e.
5695 (Limitations of Usual Tools): Describe problems of traditional
5696 egrep and fgrep with long input lines, and of traditional grep
5697 with -e.
5698 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5699 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5700 All callers changed. Append /usr/xpg4/bin to the PATH, for
5701 Solaris.
5702 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5703 the user with complaints about multiple -e options.
5704 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5705 Define it with AC_PROG_GREP.
5706 * configure.ac (AC_PROG_GREP): Add.
5707 * lib/freeze.mk (GREP): New macro.
5709 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5711 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5712 a possible candidate only after all others fail, rather than
5713 consulting it first. This improves backward compatibility by
5714 better reflecting the way shell selection occurred in previous
5715 versions of Autoconf, and should help to avoid triggering latent
5716 problems in other packages, such as the one in Automake where zsh
5717 is not handled robustly:
5718 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5719 Although it is not Autoconf's responsibility to work around
5720 problems in Automake, it nevertheless makes sense to avoid
5721 introducing unnecessary incompatibilites.
5723 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5724 Gary V. Vaughan <gary@gnu.org>
5726 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5727 how deeply nested we are when a suitable tool is found, set the
5728 ac_path_TOOL_found flag.
5729 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5730 nested we are in this macro. Break out of all 3 nested loops if
5731 ac_path_TOOL_found is set.
5733 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5735 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5736 of the _AS_PATH_WALK loop too if GNU flavor is found.
5738 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5740 * doc/autoconf.texi (Limitations of Make): Update documentation
5741 for `$<'. New entry `Long lines', based on a report from Simon
5742 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5743 paragraph about DJGPP, based on a mail from Richard Dawe.
5745 2004-04-20 Paul Eggert <eggert@twinsun.com>
5747 * tests/c.at (C keywords): Don't assume that GCC supports
5748 "restrict" and "inline", as sufficiently-old GCC versions do not
5749 (also, GCC configured to be in pedantic C89 mode does not).
5750 Problem reported by Sumit Pandya in:
5751 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5753 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5754 consider -g to work if it generates warnings when plain compiles
5755 don't. Problem reported by Braden McDaniel in:
5756 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5758 * doc/autoconf.texi (Slashes): New section, to document a problem
5759 reported by Jim Meyering in:
5760 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5762 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5763 linker output files before linking, to work around IRIX 6 linker bug.
5764 Problem reported by Rainer Orth in:
5765 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5767 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5769 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5770 best tool so far counter rely on the tool path variable name to
5771 avoid checks for one tool being affected by the results of running
5772 the length check on a previous tool.
5774 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5775 match expression argument, as different greps have different
5776 regular expression flavours.
5777 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5778 literals.
5779 (AC_PROG_EGREP): Pass 'EGREP$'.
5780 (AC_PROG_GREP): Pass 'GREP$'.
5782 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
5784 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
5785 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
5787 2004-03-29 Paul Eggert <eggert@twinsun.com>
5789 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
5790 Types, Specific Compiler Characteristics, System Services,
5791 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5792 etc. consistently instead of 'long', 'short', 'unsigned' etc.
5793 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
5794 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
5795 Likewise.
5796 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
5797 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
5798 AC_TYPE_OFF_T): Likewise.
5799 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
5800 Likewise.
5802 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
5803 pacify libtool 1.5.2. Fix quoting problems in sed command.
5805 2004-03-28 Paul Eggert <eggert@twinsun.com>
5807 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
5808 now defines HAVE_DECL_TZNAME if it is declared, when
5809 HAVE_STRUCT_TM_TM_ZONE is not defined.
5810 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5811 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
5812 for HAVE_TZNAME.
5814 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
5816 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
5817 superfluous backslashing of quotes (") in sed expressions;
5818 thanks to Paul Eggert.
5820 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
5822 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
5823 Fortran compiler is ifort, also added pghpf; thanks to Nelson
5824 H. F. Beebe for the bug report.
5826 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
5828 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
5829 quoted -cmdline argument in Portland Group compiler (bug
5830 reported by Jeffrey J. Barteet).
5832 2004-03-25 Kevin Ryde <user42@zip.com.au>
5834 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
5835 (Run Time): ... here, where it's now mentioned.
5837 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
5839 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
5840 inherits from language Autoconf-without-aclocal-m4.
5841 (Customizing autom4te): Adjust example; the cache must now be
5842 disabled for language Autoconf-without-aclocal-m4.
5844 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
5845 Nathanael Nerode <neroden@twcny.rr.com>
5847 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
5848 AC_CHECK_TOOLS): Warn if a cross-tool is found without
5849 a prefix.
5850 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
5851 AC_CHECK_TARGET_TOOLS): New macros.
5852 * doc/autoconf.texi (Generic Programs): Document
5853 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
5854 AC_CHECK_TARGET_TOOLS, and warn for future changes
5855 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
5856 AC_CHECK_TOOLS.
5857 (Specifying Names): Document the reason for these future
5858 behavioral changes.
5859 * tests/mktests.sh: Do not generate tests for the
5860 new macros.
5861 * NEWS: Document these changes.
5863 * doc/autoconf.texi: Avoid macros with unbraced arguments,
5864 they make TeX hang up.
5866 2004-03-15 Paul Eggert <eggert@bogus.example.com>
5868 * NEWS: New macro AC_CHECK_ALIGNOF.
5869 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5870 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
5871 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
5872 vowel.
5873 (AC_CHECK_ALIGNOF): New macro.
5874 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
5875 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
5876 those for sizeof.
5878 2004-03-03 Paul Eggert <eggert@twinsun.com>
5880 * bin/Makefile.am (edit): Don't use $< in a context where
5881 POSIX doesn't require support for it. Use $@.in instead.
5882 Problem reported by Anthony N. Frasso in
5883 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
5884 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
5886 2004-02-23 Gary V. Vaughan <gary@gnu.org>
5888 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
5889 from the next generation of Libtool.
5890 * lib/autom4te.in (Autoreconf-preselections): Ditto.
5892 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5894 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
5895 is not always thread-safe. Report from Nathanael Nerode.
5897 2004-02-18 Paul Eggert <eggert@twinsun.com>
5899 Fix a dependencies problem, stemming from a Autoconf 2.59 build
5900 problem on QNX reported by Stephen Rasku in
5901 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
5903 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
5904 $(m4sh_m4f_dependencies); this removes a FIXME.
5905 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
5906 (MAINTAINERCLEANFILES): Split into pieces,
5907 one per related section. Add $(srcdir)/wrapper.in.
5909 2004-02-09 Paul Eggert <eggert@twinsun.com>
5911 * doc/autoconf.texi (Setting Output Variables): Emphasize that
5912 AC_SUBST provides no portable way to escape literal newlines.
5914 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5915 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5916 Darwin uses -lcrt2.o and there's little point to cataloging all
5917 the system variants. Partial fix reported by Andreas Waechter in:
5918 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
5919 for bug reported by Nelson H. F. Beebe in:
5920 http://mail.gnu.org/archive/html/bug-autoconf/2003-12/msg00090.html
5922 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
5924 * doc/autoconf.texi (AU_DEFUN): Fix English,
5925 suggested by Paul Eggert.
5926 * lib/autoconf/autoupdate.m4: Correct reference to
5927 acobsolete.m4, suggested by Alexandre Duret-Lutz.
5929 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
5931 * bin/autoupdate.in: Define __file__ so that warnings
5932 refer to the correct file.
5933 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
5934 the behavior of the third argument.
5935 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
5936 correctly the behavior of the third argument. Document
5937 what the three macros that AU_DEFUN defines do. Fix
5938 warning message when the third argument includes $0
5939 (reported by Alexandre Duret-Lutz).
5941 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5942 Eric Sunshine <sunshine@sunshineco.com>
5943 Paul Eggert <eggert@twinsun.com>
5945 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
5946 (AS_INIT): Output shell initialization there. Removed optional
5947 parameter. Expand _AS_SHELL_FN_SPY.
5948 (AS_INIT_WITH_SHELL_FN): Removed.
5949 (_AS_SHELL_FN_SPY): New macro.
5950 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
5951 macros.
5952 (AS_SHELL_SANITIZE): Remove loop to find better shell
5953 and documentation for the parameter.
5954 (_AS_DETECT_BETTER_SHELL): Move it here.
5955 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
5956 (_AS_RUN): Move it here, support testing with eval.
5957 (AS_REQUIRE_SHELL_FN): Require shell functions when
5958 it is used.
5959 (_AS_LINENO_WORKS): Put around braces, we do not
5960 trigger the bash bug anymore.
5961 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
5962 use AS_INIT_WITH_SHELL_FN.
5963 * bin/autoconf.in, tests/wrapper.in: Regenerated.
5965 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5967 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
5968 * doc/autoconf.texi: Don't say that the third parameter
5969 is broken.
5970 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
5971 (AU_DEFUN): Honor the third parameter, create autoupdate
5972 macros with AU_DEFINE.
5973 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
5974 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
5975 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
5976 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
5977 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,
5978 AC_ARG_ARRAY, AC_CYGWIN, AC_EMXOS2, AC_MINGW32,
5979 AC_XENIX_DIR): Likewise.
5980 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS,
5981 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
5982 * lib/autoconf/status.m4: Remove FIXME.
5983 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
5984 that the macro is not present anymore in the updated
5985 configure.ac.
5986 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
5987 of autoupdate.
5989 2004-01-28 Paul Eggert <eggert@twinsun.com>
5991 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
5992 copyright years.
5993 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
5994 2003 (except 1997) to the list of copyright years. This undoes
5995 the 2003-05-22 change, which removed the older years from the list.
5996 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
5998 2004-01-27 Gary V. Vaughan <gary@gnu.org>
5999 Albert Chin-A-Young <china@thewrittenword.com>
6001 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
6002 grep or ggrep program in PATH that accepts as long lines as
6003 possible.
6004 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
6005 AC_PROG_GREP.
6006 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
6007 egrep and fgrep respectively if $GREP -E/-F don't work.
6008 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
6009 _AC_PROG_GREP, and AC_PROG_SED.
6010 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
6011 longest input length accepted by a command.
6012 (AC_PROG_SED): Use it.
6013 * doc/autoconf.texi (Particular Programs): Document the changes.
6014 * NEWS: Updated.
6016 2004-01-27 Paul Eggert <eggert@twinsun.com>
6018 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
6019 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
6020 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
6021 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
6023 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
6024 bin/autoconf.in, config/Makefile.in, config/config.guess,
6025 config/config.sub, config/install-sh, config/mdate-sh,

6036 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
6037 tests/actypes.at: Regenerate and/or sync with original
6038 sources.
6040 2004-01-26 Paul Eggert <eggert@twinsun.com>
6042 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6043 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6044 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6045 not <inttypes.h>. Problem reported by Tim Mooney in
6046 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6047 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6048 Likewise.
6050 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6051 otherwise "make check" fails because it forbids cmp (I guess
6052 because cmp treats files as binary on DOS-like systems).
6054 * tests/mktests.sh: Update copyright date to 2004, since some tests
6055 have changed in 2004.
6057 2004-01-23 Gary V. Vaughan <gary@gnu.org>
6059 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
6060 non-truncating sed or gsed program in PATH.
6061 * tests/acprograms.at: Add it.
6062 * doc/autoconf.texi (Particular Programs): Document it.
6063 * NEWS: Updated.
6065 2004-01-15 Paul Eggert <eggert@twinsun.com>
6067 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6068 -std1 disables some useful extensions on Tru64. Problem reported
6069 by N. Lichtmaier in
6070 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6072 2004-01-14 Paul Eggert <eggert@twinsun.com>
6074 * doc/autoconf.texi (Programming in M4sh): Document that
6075 AS_MKDIR_P succeeds if the destination is a symbolic link
6076 to an existing directory.
6077 (Limitations of Usual Tools): Note that mkdir -p might not
6078 succeed on symlinks to directories.
6080 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6082 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6083 * bin/autoheader.in: Grammar fix in message.
6084 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6085 Test for dir before calling mkdir -p. (trivial changes)
6087 2004-01-13 Eric Blake <ebb9@byu.net>
6089 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6090 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6092 2004-01-10 Jim Meyering <jim@meyering.net>
6094 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6096 2004-01-09 Paul Eggert <eggert@twinsun.com>
6098 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6099 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6100 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6101 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6102 AC_COMPILE_IFELSE, since we now assume our caller invokes
6103 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6104 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6105 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6106 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6108 2004-01-07 Paul Eggert <eggert@twinsun.com>
6110 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6111 `"'...'"`, as it's confusing (and I suspect it may not work on
6112 some platforms). The code was incorrect anyway, as it assumed
6113 that \$ evaluated to itself in that context. Reported by
6114 Alexandre Duret-Lutz.
6116 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6118 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6119 and _LT_AC_TAGCONFIG.
6121 2004-01-06 Paul Eggert <eggert@twinsun.com>
6123 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6124 example, and add more examples. Reported by Eric Sunshine.
6126 2004-01-05 Paul Eggert <eggert@twinsun.com>
6128 * doc/autoconf.texi (Limitations of Usual Tools):
6129 Remove warning against "rm -fr" introduced yesterday; it
6130 was a false alarm.
6132 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6133 autoscan, autoupdate, ifnames): Don't use chmod -w.
6134 * lib/Makefile.am (autom4te.cfg): Likewise.
6135 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6136 "chmod -w".
6138 2004-01-04 Paul Eggert <eggert@twinsun.com>
6139 Paolo Bonzini <bonzini@gnu.org>
6141 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
6142 by doing lineno substitution only on lines containing "$LINENO".
6144 2004-01-04 Paul Eggert <eggert@twinsun.com>
6146 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6147 Use "rm -f" to remove conftest.sed, not plain "rm".
6148 Bug reported by David Relson in
6149 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6151 * Makefile.am (autom4te-update):
6152 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6153 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6154 * doc/autoconf.texi (Guidelines): Likewise.
6155 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

6160 * tests/Makefile.am (clean-local): Likewise.
6161 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6162 srcdir): Likewise.
6163 * doc/autoconf.texi (Limitations of Usual Tools):
6164 Warn against "rm -fr".
6166 2004-01-03 Paul Eggert <eggert@twinsun.com>
6168 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6169 -c -o might not work. From a suggestion by Kevin Ryde.
6170 (C Compiler, Generating Sources, Limitations
6171 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6172 Don't put '-o' after non-options, as POSIX doesn't allow this.
6173 Mention that cc's name might be gcc or c89 or whatever.
6175 2004-01-04 Kevin Ryde <user42@zip.com.au>
6177 * doc/autoconf.texi: Add various further index entries.
6179 2003-12-29 Paul Eggert <eggert@twinsun.com>
6181 * bin/autoreconf.in (autoreconf_current_directory):
6182 Fix typo: mkdir without umask arg.
6184 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6186 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6187 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6188 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6189 explanation clearer.
6191 2003-12-24 Andreas Schwab <schwab@suse.de>
6193 * doc/autoconf.texi (Default Includes): Fix misspelling of
6194 AC_INCLUDES_DEFAULT.
6196 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6198 * configure.ac: Test if sh -n works.
6199 * configure: Regenerate.
6200 * tests/atlocal.in: Store the result here.
6201 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6202 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6203 of explicitly testing.
6204 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6205 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6206 * tests/tools.at (Syntax of the shell scripts): Simplify
6207 using AT_CHECK_SHELL_SYNTAX.
6208 (Syntax of the Perl scripts): Remove definition of
6209 AT_CHECK_PERL_SYNTAX.
6211 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6213 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
6214 stderr to /dev/null.
6215 * bin/autoconf.in: Regenerate.
6216 * bin/wrapper.in: Regenerate.
6218 2003-11-26 Paolo Bonzini <bonzini@gnu.org>
6220 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
6221 Extracted from AS_SHELL_SANITIZE.
6222 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
6223 macros.
6224 (AS_SHELL_SANITIZE): Move reinvocation code from
6225 _AS_LINENO_WORKS, use it to find out if shell
6226 functions work.
6227 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6228 does not work.
6229 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
6230 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
6231 was called.

6240 * config/announce-gen (&print_locations, &print_signatures)
6241 (&sizes): New.
6242 Use them.

6244 them on the fly.
6246 2003-11-24 Akim Demaille <akim@epita.fr>
6248 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6276 parameter of AU_DEFUN.
6277 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.

6281 the expanded body, consistently with other macros such as AC_USG.
6283 2003-11-17 Paul Eggert <eggert@twinsun.com>
6285 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
6286 into the initial confdefs.h, to work around a bug in NextStep 3.3
6287 patch 3 reported by Eric Sunshine.
6289 2003-11-15 Kevin Ryde <user42@zip.com.au>
6291 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
6292 than $target since the latter is not usual, add guidelines on when to
6293 use or not use the system type.
6295 2003-11-12 Derek Price <derek@ximbiot.com>
6297 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
6298 typo misrepaired by an auto-spellcheck.
6300 2003-11-12 Akim Demaille <akim@epita.fr>

6303 --force-missing unless it actually supports it.
6304 From Debian #219336.
6306 2003-11-12 Akim Demaille <akim@epita.fr>

6374 2003-10-28 Akim Demaille <akim@epita.fr>
6376 * Makefile.cfg (local_updates, executable-update): Tweak to be

6450 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
6452 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
6453 cross test.
6455 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
6457 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
6458 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

6469 Issue a more-informative diagnostic.
6470 Problems reported by Eric Sunshine.
6472 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6474 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6475 -mGLOB_options_string stuff for Intel ifc, which can cause

6485 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
6486 that future autopoint/aclocal/automake/autoreconf will be able

6495 -lcrt[01].o.
6497 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
6499 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6500 cache variable instead of $G77 to decide whether to include -O2,
6501 since $G77 is specific to Fortran 77.

6505 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
6506 free" flag. Re-order flags tested into rough order of popularity.
6508 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6510 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6511 arguments so that it can be used with syntax identical to
6512 AC_PROG_F77, and so that we can more easily decide to
6513 remove/deprecate the DIALECT optional argument in the future if it
6514 proves troublesome.
6515 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
6516 non-freeform-supporting compilers. Document freeform flags.
6518 2003-10-03 Akim Demaille <akim@epita.fr>
6520 * configure.ac: Look for emacs, not macs.
6521 Reported by Eric Sunshine.
6523 2003-10-03 Akim Demaille <akim@epita.fr>
6525 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
6526 * bin/autoreconf.in (autoreconf_current_directory): Create the

6530 2003-10-03 Akim Demaille <akim@epita.fr>
6532 * configure.ac: Quotation and formatting changes.

6553 * lib/Autom4te/XFile.pm: Use Errno.
6554 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
6555 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
6557 2003-09-30 Akim Demaille <akim@epita.fr>
6559 * config/announce-gen (&print_news_deltas): Extracted from...
6560 (&print_changelog_deltas): here.

6579 Problem reported by Lars J. Aas in
6580 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
6581 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6582 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6583 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6585 2003-09-26 Akim Demaille <akim@epita.fr>
6587 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6588 directory for AC_CONFIG_COMMANDS' first argument exists.
6589 This makes valid the invocation of _AC_SRCPATH that follows.
6590 Reported by Eric Sunshine.
6591 * doc/autoconf.texi (Configuration Commands): Adjust.
6593 2003-09-26 Akim Demaille <akim@epita.fr>
6595 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6596 Reported by Ralf Corsepius.
6598 2003-09-26 Akim Demaille <akim@epita.fr>
6600 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6601 arguments.
6602 Actually, use AU_ALIAS.
6603 From Bruno Haible.
6605 2003-09-26 Paul Eggert <eggert@twinsun.com>
6607 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,

6612 2003-09-26 Akim Demaille <akim@epita.fr>
6614 The test suite are sometimes assigning timings incorrectly.
6615 Reported by Henk Krus.
6616 Diagnosed by Nicolas Joly.
6618 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6619 AT_help_all.
6620 Instead of making AT_help a sequence of assignments to grow
6621 $at_help_all, just make AT_help_all be the growing contents of
6622 $at_help_all, and make a single assignment in...
6623 (AT_INIT): here.
6624 (at_times_skip): Flip the meaning and rename as...
6625 (at_times_p): this.
6626 (AT_INIT): When summarizing the test that ran, remove
6627 $at_times_file after use, and check it is present before trying to
6628 use it.
6630 2003-09-25 Akim Demaille <akim@epita.fr>
6632 Version 2.57d.
6634 * bin/Makefile.am (edit): Handle '@configure_input@'.
6635 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6636 (ifnames): chmod -w.
6637 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6638 executables, not bin/ executables! Otherwise all the magic needed
6639 to find non installed files is turned off. This caused a failure
6640 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6641 as found in its environment (sent by tests/autoreconf): pointing
6642 to bin/autom4te that could not find its files.
6643 * tests/mktests.sh: Force the replacement of generated files, for
6644 the sake of "mv" program that are interactive when overwriting a
6645 -w file.
6646 * config/install-sh: Upgrade from CVS Automake.
6648 2003-09-23 Paul Eggert <eggert@twinsun.com>
6650 * doc/autoconf.texi (Limitations of Builtins): Document test -h
6651 versus test -L issues.
6653 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
6654 Paul Eggert <eggert@twinsun.com>
6656 Trivial change to support GCC's configuration procedure.
6657 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6658 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6659 about inconsistency if the preprocessor is set to give errors for
6660 any warning.
6661 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6663 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
6665 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
6666 and XFile.pm from Automake.

6681 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
6682 not asm/types.h.
6684 2003-09-11 Akim Demaille <akim@epita.fr>
6686 * doc/autoconf.texi (Header Portability): linux/random.h.
6687 From Peter Hendrickson.
6689 2003-09-10 Akim Demaille <akim@epita.fr>
6691 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6692 willing to edit the output files.
6694 2003-09-10 Akim Demaille <akim@epita.fr>
6696 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6697 and AC_FC_FREEFORM.
6698 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6699 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
6701 2003-09-09 Akim Demaille <akim@epita.fr>

6715 Improve the accuracy of the wording about obsolescence.
6716 From a suggestion by Ian Lance Taylor in
6717 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
6719 2003-09-05 Paul Eggert <eggert@twinsun.com>
6721 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6722 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6724 2003-09-04 Akim Demaille <akim@epita.fr>
6726 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6727 AC_FUNC_WAIT3.
6729 2003-09-04 Akim Demaille <akim@epita.fr>
6731 * bin/autom4te.in: Use &fatal where more appropriate than &error.
6732 (freeze): When exiting, use $exit_code.

6739 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6741 Add support for newer Fortran dialects. The F77 interface is
6742 unchanged, and continues to support Fortran 77. New FC macros
6743 correspond to all the old F77 macros, with output variables FC,
6744 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6745 available dialect, but older dialects can be specified. There are
6746 new macros AC_FC_SRCEXT to set the source extension, and
6747 AC_FC_FREEFORM to accept free-form source files.
6749 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
6750 New macros.
6751 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

6767 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
6768 Rewrite in terms of the above.
6769 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
6770 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

6776 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
6777 Document problems with timestamp resolution that 'make', 'cp -p', and
6778 'touch -r' have.
6780 2003-08-27 Akim Demaille <akim@epita.fr>
6782 * tests/m4sugar.at (cross_warning): Make sure to enable the
6783 output, so that we can track spurious m4sugar output.

6785 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
6786 are defaulted by AT_CHECK anyway.
6787 Use AT_CHECK_AUTOM4TE.
6788 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
6789 missing dnl.
6791 2003-08-27 Akim Demaille <akim@epita.fr>
6793 * bin/autoheader.in: Issue the "Using auxiliary..." message only
6794 when -Wobsolete is set.
6795 Set it on by default.
6796 Suggested by Klee Dienes.
6798 2003-08-27 Akim Demaille <akim@epita.fr>
6800 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
6801 documentation.
6802 From Guido Draheim.
6804 2003-08-26 Akim Demaille <akim@epita.fr>
6806 * doc/autoconf.texi (Output): Make clear that one can run code
6807 after AC_OUTPUT.
6809 2003-08-25 Akim Demaille <akim@epita.fr>
6811 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
6812 CVS Bison.
6814 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
6816 * bin/autoreconf.in (parse_args): Do not pass --no-force to
6817 Automake versions prior to 1.8.
6819 2003-08-25 Akim Demaille <akim@epita.fr>

6826 * configure.ac: Bump to 2.57c.
6828 2003-08-22 Akim Demaille <akim@epita.fr>
6830 Version 2.57b.
6832 * Makefile.cfg (local-checks-to-skip): New.
6833 * Makefile.maint (local-check): Rename as...
6834 (local-checks-available): this.
6835 (local-check): New.
6837 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
6838 * configure.ac: Require Automake 1.7.6.
6840 2003-08-22 Akim Demaille <akim@epita.fr>
6842 Output stack traces in warnings.
6844 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
6845 Replace the former...
6846 (m4_warn): Pass the call stack to _m4_warn.
6847 * bin/autom4te.in: Adjust to output the call stack.
6848 * tests/m4sugar.at (m4@&t@_warn): Adjust.
6850 2003-08-22 Akim Demaille <akim@epita.fr>
6852 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
6853 * bin/autom4te.in: Adjust.
6855 2003-08-21 Akim Demaille <akim@epita.fr>
6857 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
6858 (&verbose): Remove.
6859 (&getopt): Adjust the note and verb channels, depending upon
6860 --verbose.
6861 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
6862 * bin/autoupdate.in: Adjust.
6863 Use &verb, not &verbose.
6865 2003-08-21 Akim Demaille <akim@epita.fr>
6867 * bin/autoheader.in (&parse_args): Use &parse_warnings and
6868 &parse_WARNINGS.
6869 ($help): Use Autom4te::ChannelDefs::usage.
6870 * bin/autoscan.in: Use Autom4te::ChannelDefs.
6871 * lib/Autom4te/General.pm: Don't export error: you don't own it.
6873 2003-08-21 Akim Demaille <akim@epita.fr>
6875 First stab at preserving warnings between calls to autom4te,
6876 including when the cache is used.
6878 There are still several issues: (i) there are too many runs of m4
6879 (one for include, one for warnings, and some more), (ii) warnings
6880 spreading on several lines are not handled gracefully, (iii) the
6881 code meant to have the call stack display for errors does not work
6882 (its handling should move from m4 to autom4te).
6884 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6885 Use them.
6886 (@preselect): Add m4_warn.
6887 ($exit_status): Remove, use $exit_code.
6888 ($help): Use Autom4te::ChannelDefs::usage.
6889 (&handle_m4): No longer define the m4_warnings.
6890 At each run, extract and report the warnings.
6891 Always cache the result, including if the exit status is on
6892 failure, since if nothing changes, we should result in the same
6893 failure, hence we can use the cache.
6894 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6895 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6896 Remove.
6897 (m4_warn): Redefine as a do-nothing: it is its invocation that
6898 matters, as warnings are now reported via traces.
6899 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6900 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6901 the latter reveals calls to the former.
6903 Adjust the tests.
6905 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6907 2003-08-21 Akim Demaille <akim@epita.fr>
6909 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
6910 Use them.
6912 2003-08-21 Akim Demaille <akim@epita.fr>
6914 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
6915 forward order.
6916 * lib/Autom4te/ChannelDefs.pm: Doc typos.
6917 (&parse_warnings): Accept a list of warning requests.
6918 (&usage): Return a string, not a side effect.
6919 (cross): New warning category.
6921 2003-08-21 Akim Demaille <akim@epita.fr>
6923 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
6924 (&require_configure_ac): Accept an optional directory argument.
6925 ($configure_ac): Remove.
6926 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
6927 (&catfile): Remove.
6928 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
6929 * bin/autoscan.in: Adjust.
6931 2003-08-20 Akim Demaille <akim@epita.fr>
6933 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
6934 Reported by Alexandre Duret-Lutz.
6936 2003-08-20 Akim Demaille <akim@epita.fr>
6938 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
6939 * bin/autom4te: Adjust.
6940 In particular, be Autoconf tools are really silent when properly
6941 working, bind the verbosity of the 'note' channel to $verbose.
6942 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
6943 (&xsystem, &contents): Remove, since they are exported by...
6944 * lib/Autom4te/FileUtils.pm: this.
6945 More perldoc.
6946 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
6947 * lib/Autom4te/FileUtils.pm: here.
6949 2003-08-20 Akim Demaille <akim@epita.fr>
6951 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
6952 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
6953 from CVS Automake.
6955 2003-08-20 Akim Demaille <akim@epita.fr>
6957 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
6958 (autom4te-update): New.
6959 * Makefile.cfg (update): Bind autom4te-update.
6961 2003-08-19 Derek Price <derek@ximbiot.com>
6963 * lib/autotest/general.m4: Comment various HELP_* diversions.
6964 (PARSE_ARGS_BEGIN): New section for option parsing related
6965 initialization.
6966 (AT_ARG_OPTION,AT_ARG_OPTION_ARG,_AT_ARG_OPTION): New macros to define
6967 package specific options and associated help.

6971 * config/announce-gen, Makefile.cfg: New.
6972 * Makefile.am: Adjust.
6973 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
6975 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
6977 * lib/autom4te.in (Automake-preselections): Preselect
6978 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
6979 and m4_sinclude.
6981 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
6983 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
6984 (Autoconf-without-aclocal-m4): ... this new language.
6985 * doc/autoconf.texi (autom4te Invocation): Mention
6986 Autoconf-without-aclocal-m4.

6990 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
6991 RUN-IF-PASS optional arguments.

7000 STDOUT & STDERR arguments.
7002 2003-08-14 Derek Price <derek@ximbiot.com>
7004 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
7005 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7006 shorter column three. Add DESCRIPTION to log file content.
7008 2003-08-13 Derek Price <derek@ximbiot.com>
7010 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7011 output.
7013 2003-08-12 Derek Price <derek@ximbiot.com>
7015 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
7016 (AT_CHECK_NOESCAPE): Move core functionality to...
7017 (_AT_CHECK): ...this new macro.
7019 2003-08-07 Derek Price <derek@ximbiot.com>
7021 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
7022 (AT_CHECK_NOESCAPE): ...to this new macro.
7024 2003-07-31 Paul Eggert <eggert@twinsun.com>
7026 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7027 in Bash 2.01. Problem reported by Brian Gough in
7028 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
7030 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
7032 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7033 -lcrt1.o, for OS X. (trivial change)
7035 2003-07-07 Paul Eggert <eggert@twinsun.com>
7037 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7038 inside '#ifndef __cplusplus'. Problem reported by
7039 Bob Friesenhahn.
7041 2003-07-06 Bill Clarke <llib@computer.org>
7043 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7044 'long', not 'int', for benefit of Sun's recent C++ compilers
7045 (trivial change). See:
7046 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7047 (This really should be 'intptr_t', not 'long', but that would
7048 take more work.)
7050 2003-06-25 Akim Demaille <akim@epita.fr>
7052 * lib/Makefile.am (autom4te.cfg): Make it read only.
7053 Depend on Makefile since it contains substitutions.
7054 From Paolo Bonzini.
7055 * lib/autom4te.in (args): Add local.at? for Autotest args.
7056 This change was made on autom4te.cfg which is generated.
7057 Reported by Raja R. Harinath.
7059 2003-06-25 Akim Demaille <akim@epita.fr>
7061 * doc/autoconf.texi (Header Portability): sys/mount.h.
7062 From Gareth McCaughan.
7064 2003-06-23 Akim Demaille <akim@epita.fr>
7066 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7067 not all of them. This fixes 1. the fact that when testing
7068 Autoconf there are many many config.log, 2. the incorrect use of
7069 top_srcdir to find config.log.
7070 Don't mix the detailed output of failed test with the summary of
7071 failures. Rather, append detailed log afterwards.
7073 2003-06-23 Akim Demaille <akim@epita.fr>
7075 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7076 always run: output config.log on $at_group_log.
7078 2003-06-23 Akim Demaille <akim@epita.fr>
7080 * tests/torture.at (#define header templates): Don't use quotes in
7081 C++ comments as it puzzles Emacs' sh font-lock-mode.
7083 2003-06-23 Akim Demaille <akim@epita.fr>
7085 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7086 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
7087 * tests/atspecific.m4: Rename as...

7090 * tests/local.at: here.
7091 * tests/Makefile.am: Adjust.
7092 * doc/autoconf.texi (testsuite Scripts): Adjust.
7094 2003-06-21 Kevin Ryde <user42@zip.com.au>
7096 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7097 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7098 ensuring we add -std1 for full-ANSI.
7100 * doc/autoconf.texi (hdrindex): New macro.
7101 Add index entries for portability of various standard header files.
7103 2003-06-20 Akim Demaille <akim@epita.fr>
7105 * configure.ac: Bump to 2.57b.
7107 2003-06-20 Akim Demaille <akim@epita.fr>
7109 Version 2.57a.
7111 2003-06-20 Akim Demaille <akim@epita.fr>
7113 * bin/autom4te.in: Don't rely on $HOME being defined.
7114 Reported by Marc Espie as PR/233.
7116 2003-06-20 Akim Demaille <akim@epita.fr>
7118 * lib/autotest/general.m4: Use at_times_file only if used.
7119 From Nicolas Joly.
7121 2003-06-20 Akim Demaille <akim@epita.fr>
7123 * config/config.guess, config/config.sub, config/elisp-comp,
7124 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7125 Update from masters.
7127 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7129 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7130 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7131 (TEST_SCRIPT): New diversion.
7132 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7133 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7134 (AT_INIT): Support for expected failures.
7136 2003-06-02 Akim Demaille <akim@epita.fr>
7138 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7139 changes.
7140 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7141 Autoconf nor Automake.
7142 (&contents): New, from Automake.
7143 PODify.
7145 2003-05-28 Paul Eggert <eggert@twinsun.com>
7147 * NEWS, doc/autoconf.texi (Particular Functions),
7148 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7149 is the inverse of localtime.
7151 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7153 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7154 (handle_exec_errors): New function. Work around $! being
7155 altered by WEXITSTATUS.
7156 (xqx, xsystem): Use handle_exec_errors.
7158 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7160 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7161 Do not call `_exit()', simply modify `$?'.
7162 (xsystem): Reset $! before running system, and check it afterward.
7163 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7164 63 for version mismatches.
7166 2003-05-23 Akim Demaille <akim@epita.fr>
7168 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7169 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7170 the middle of a line).
7171 * lib/m4sugar/m4sugar.m4: Likewise.
7172 Remove useless spaces in comments.
7174 2003-05-23 Akim Demaille <akim@epita.fr>
7176 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7177 exit 63, so that we (or Automake's "missing") can tell the
7178 difference with a plain failure.
7179 * doc/autoconf.texi (Notices): Adjust.
7181 2003-05-23 Akim Demaille <akim@epita.fr>
7183 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7184 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7185 White spaces cleanup.
7187 2003-05-22 Jim Meyering <jim@meyering.net>
7188 Paul Eggert <eggert@twinsun.com>
7190 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7191 Remove `#include <stdlib.h>' from the list; we should never
7192 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7193 resulting namespace pollution would cause other tests to fail.
7194 Configure scripts run with some older versions of g++ and HP's
7195 aCC would fail due to such an #include. Problems reported by
7196 Matthew Mueller in <http://bugs.debian.org/120704> and by
7197 Keith Bostic in
7198 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7199 In the test, use the test declaration before including <stdlib.h>,
7200 as that's closer to how it'll be used.
7202 2003-05-23 Akim Demaille <akim@epita.fr>
7204 * doc/autoconf.texi (Header Portability): ucred.h.
7205 From Ian Redfern.
7207 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7209 Overhaul Autotest's logging: generate separate log files
7210 in testsuite.dir/NNN/testsuite.log, and append them to
7211 testsuite.log instead of re-running the test verbosely.
7213 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7214 file descriptor, write 0 to at_status_file instead of setting
7215 at_status=0, initialize some new variables (at_status_file,
7216 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7217 to rerun the tests, instead append the at_group_log to the
7218 at_suite_log when a test fails.
7219 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7220 with the AS_MESSAGE_LOG_FD redirected to stdout.
7221 (AT_CLEANUP): save the output status in $at_status_file
7222 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7223 its original place.
7224 (AT_CHECK): since tests are run with a redirected stdout,
7225 and used to be re-run in verbose mode, turn some $at_verbose
7226 into echo, and don't redirect the output of testing stdout
7227 and stderr.
7229 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7230 the name of the debugging directory and information about
7231 its contents.
7233 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7235 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
7236 parameter.

7265 Reported by Jim Meyering.
7267 2003-05-22 Akim Demaille <akim@epita.fr>
7269 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

7348 and truncate.
7350 2003-05-06 Akim Demaille <akim@epita.fr>
7352 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7353 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7354 by aclocal.m4 is changed it might require the importing of another
7355 m4 extension file, i.e., aclocal must be run.
7357 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7358 (&parse_args): Use --force with aclocal if required and supported.
7359 (&autoreconf_current_directory): Use &run_aclocal.

7366 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7367 argument instead of a file name, so that the request file remains
7368 open during the whole autom4te run.
7369 ($icache_file): New.
7370 (&freeze): Lock the $icache_file.
7372 2003-04-29 Derek Price <derek@ximbiot.com>
7374 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7375 seperator with m4_append_uniq(). It doesn't work.
7376 (AT_CLEANUP): Add `;' to end of at_help_all.
7377 (AT_INIT): Allow --keywords to be specified more than once. When
7378 grepping $at_help_all for keywords, use the field and keyword
7379 seperators to ensure a complete keyword match. Alter at_prev handling
7380 to support the new --keywords behavior.
7382 2003-04-27 Karl Berry <karl@freefriends.org>
7384 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7385 align better with others. I also made some of the individual
7386 entries on one line, for brevity and to make it easier for me to
7387 sort my dir-example file in the Texinfo distribution :).

7454 header causes problems.
7456 2003-03-28 Akim Demaille <akim@epita.fr>
7458 * tests/torture.at (Configuring subdirectories): Require aclocal
7459 1.4, otherwise the test fails, as it does support configure.ac.

7464 * doc/autoconf.texi (C Compiler): `#line' portability.

7470 layout in order to allow scripting around test groups.
7472 2003-03-27 Derek Price <derek@ximbiot.com>

7475 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
7476 use new diversions in preparation for accepting new arguments and

7484 (AC_HELP_STRING): AU_DEFUN to...
7485 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
7486 * tests/m4sh.at (AS_HELP_STRING): New test.
7488 * tests/acgeneral.at: Regenerated.
7490 2003-03-26 Derek Price <derek@ximbiot.com>
7492 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
7493 sense. Verbosify the diversion definitions comment.

7497 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

7532 Tru64 make in the "target lookup" section.
7533 (Automake): Automake 1.5+ no longer requires special tools to be
7534 present on the developer's host.

7543 * bin/autoreconf.in (BEGIN): Likewise.
7544 * bin/autoscan.in (BEGIN): Likewise.
7545 * bin/autoupdate.in (BEGIN): Likewise.

7548 * bin/ifnames.in: Add final newline to help and version messages.
7550 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
7551 to cope with DOS-style absolute paths, when constructing
7552 ${ac_make}.
7554 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
7555 When constructing paths with IFS=:, quote the path. If we're
7556 constructing a DOS-style absolute path, we don't want to split it
7557 on the colon.
7559 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
7560 in description.
7562 2003-02-25 Pavel Roskin <proski@gnu.org>

7570 2002-09-01 patch by replacing "test -n" with "test -z".
7571 This fixes a bug found by Jeff Painter and reported by Tom Epperly in

7574 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
7575 to fix a mismatch between example and discussion.
7577 2003-02-24 Kevin Ryde <user42@zip.com.au>
7579 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
7580 format starting with "-".
7582 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7584 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
7585 is not portable inside Makefile.
7587 2003-02-20 Akim Demaille <akim@epita.fr>
7589 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7590 compiler says yeah, but preproc says nope, compiler is right.
7591 Conversely, prompt the reader to send a bug report to the
7592 maintainers of the package, not of Autoconf.
7594 2003-02-20 Klee Dienes <kdienes@apple.com>
7596 * bin/autoreconf.in (autoreconf_current_directory): Properly
7597 handle an empty aclocal.m4.

7601 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
7602 $ac_prefix_program.
7603 From Larry Jones.
7605 2002-12-23 Paul Eggert <eggert@twinsun.com>
7607 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7608 innocuous variant befor including <limits.h> or <assert.h>. This
7609 works around a bug reported by Albert Chin: HP-UX 11i
7610 (and earlier versions) have a <limits.h> that declares
7611 gettimeofday and many other functions.
7613 2002-12-03 Paul Eggert <eggert@twinsun.com>
7615 Version 2.57.
7617 * NEWS, configure.ac: Update version.
7619 * doc/fdl.texi: Upgrade to FDL version 1.2.
7621 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7622 nontrivially in main's body, so that f's external declaration is
7623 not optimized away in AIX. This should fix the bug reported by
7624 Martin Frydl in
7625 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7627 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7628 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7629 defined, to support freestanding compilers. This should fix the
7630 bug reported by Momchil Velkov in
7631 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7633 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7634 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
7635 obsolete AC_CHECK_TYPE. The missing empty arg was reported
7636 by Simon Josefsson in

7639 * Makefile.maint (www-gnu): New macro.
7640 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
7641 the location has moved.
7643 2002-12-02 Martin Frydl <martin@systinet.com>
7645 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
7646 \(.*\) match is too long and there is something more to be checked.
7647 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
7649 2002-11-15 Akim Demaille <akim@epita.fr>

7653 * config/install-sh: chmod +x.
7654 From Paul Eggert.
7655 * config/move-if-change: Indenting changes.
7656 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
7657 * configure.ac (AM_INIT_AUTOMAKE): here.
7658 Require 1.7.1.
7660 2002-11-14 Akim Demaille <akim@epita.fr>
7662 Version 2.55.
7664 * config/config.guess, config/config.sub, config/install-sh:
7665 Update from masters.
7667 2002-11-14 Akim Demaille <akim@epita.fr>
7669 * Makefile.maint: Sync with Bison, i.e.:
7670 (po-check): Scan .l and .y files instead of the
7671 .c and the .h files that they generate. This fixes the bug
7672 reported by Tim Van Holder in:
7673 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7674 Look for N_ as well as for _. Try to avoid matching #define for
7675 N_ and _.
7676 From Paul Eggert.
7678 2002-11-14 Akim Demaille <akim@epita.fr>
7680 * doc/autoconf.texi (C Compiler): Compiling several files at once.
7681 From Paul Eggert and Albert Chin-A-Young.
7683 2002-11-14 Akim Demaille <akim@epita.fr>
7685 * doc/autoconf.texi (C Compiler): Solitary backslashes.
7686 From Paul Eggert and Albert Chin-A-Young.
7688 2002-11-14 Kevin Ryde <user42@zip.com.au>
7690 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
7691 than assigning in main, to avoid HP cc +O3 optimizing it away.
7693 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
7695 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
7696 option. Process --recheck after parsing all options. Pass -q
7697 option to configure on --recheck.
7698 (AC_OUTPUT): Pass -q from configure to config.status.
7699 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
7700 arguments to record.
7701 * doc/autoconf.texi (config.status Invocation): Document
7702 config.status -q option.
7704 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
7706 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
7707 Makefile.in if Makefile.am exists.
7708 (output): Strip `.am' from Makefiles. Don't
7709 output AC_CONFIG_FILES if no Makefiles were found.
7711 2002-11-07 Akim Demaille <akim@epita.fr>
7713 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
7714 (local_updates): New.
7715 * Makefile.maint: Update, from CVS Bison.
7716 (local_updates): New.
7718 2002-11-06 Akim Demaille <akim@epita.fr>
7720 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
7721 declaration in extern "C" too.
7722 Reported by Roberto Bagnara.
7724 2002-11-06 Akim Demaille <akim@epita.fr>
7726 * tests/torture.at (Configuring subdirectories): Don't use grep
7727 -w.
7728 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
7729 Reported by Ezra Peisach.
7731 2002-11-05 Akim Demaille <akim@epita.fr>
7733 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7734 Remove.
7735 We _have_ to stop using the old compatibility scheme that tried to
7736 avoid useless backslashes because Libtool 1.4.3 contains a
7737 AC_DEFINE([error_t], [int],
7738 [Define to a type to use for \`error_t' if it is not
7739 otherwise available.])
7740 We _have_ to quote the single quote and backslashes with \. The
7741 old compatibility scheme saw that ` was backslashed, and therefore
7742 did not quote the single quote. Hence before this patch, Autoconf
7743 was not compatible with Libtool.
7745 2002-11-04 Paul Eggert <eggert@twinsun.com>
7747 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
7748 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
7749 LC_NAME, LC_PAPER, LC_TELEPHONE.
7750 * doc/autoconf.texi (Special Shell Variables): Mention those vars.
7752 2002-11-04 Akim Demaille <akim@epita.fr>
7754 Version 2.54c.
7756 * Makefile.maint (update, cvs-update, po-update, do-po-update):
7757 New.
7758 * config/texinfo.tex: Update.
7760 2002-11-03 Akim Demaille <akim@epita.fr>
7762 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
7763 from...
7764 (&autoreconf): here.
7765 ($help, $make, &parse_args, &autoreconf_current_directory):
7766 Support -m/--make.
7767 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7769 2002-10-31 Bruno Haible <bruno@clisp.org>

8075 2002-10-22 Akim Demaille <akim@epita.fr>

8081 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
8082 strings.
8084 2002-10-22 Akim Demaille <akim@epita.fr>
8086 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

8133 longer required can still cause errors.
8134 Reported by Alexandre Duret-Lutz.
8136 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8137 to frozen files in @ARGV, as @ARGV must remain being a list of

8140 (&freeze): Use &error.
8141 (&up_to_date): If a file that was included according to the cache
8142 is no longer there, then the output is out dated.

8144 --force is given.
8145 * tests/tools.at (autom4te cache): New.
8147 2002-10-16 Akim Demaille <akim@epita.fr>

8154 that error messages can be easily located, and use GNU Make
8155 format, so that Emacs' compile mode understands us.
8156 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8157 if some file was changed instead of `print'.
8158 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

8192 file name to enable parallel executions.
8193 From Sam Varshavchik.
8195 2002-10-08 Akim Demaille <akim@epita.fr>
8197 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8198 aclocal invocation, as Gettext macros might not be visible to
8199 aclocal.
8200 Instead of blindly running autopoint, scan configure.ac (not the
8201 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8202 Reported by Paul D. Smith.
8204 2002-10-08 Paul Eggert <eggert@twinsun.com>
8206 Work around problems found when POSIXLY_CORRECT=1 is set.
8207 None of this seems to have anything to do with POSIX, really,
8208 but it's how Perl getopt works.
8209 * bin/autom4te.in (parse_args): Configure GetOpt with
8210 "permute", too.
8211 * doc/autoconf.texi (Invoking autom4te):
8212 --warning -> --warnings.

8234 * tests/torture.at (Configuring subdirectories): Be robust to
8235 users who use config.site to require for a cache: in this case,
8236 the two last configure runs, using two different sets of
8237 arguments, trigger a legitimate error.
8239 2002-09-28 Akim Demaille <akim@epita.fr>

8255 (tm_zone): Move their rules to...
8256 * lib/autoconf/types.m4: here, using AN_ macros.
8257 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8258 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8259 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

8265 2002-09-28 Akim Demaille <akim@epita.fr>
8267 * lib/autoconf/autoscan.m4: New file.
8268 * lib/autoconf/autoconf.m4: Include it.
8269 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
8270 that were listed in the original autoscan.list.
8271 * lib/autoconf/headers.m4: Similarly with headers.
8272 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8273 (.m4.m4f): Don't pass --prepend-include, since that's done by
8274 tests/autom4te itself.
8275 * lib/autoscan/Makefile.am: Include freeze.mk.
8276 (autoscan.list): New target --this file is no longer a source.
8277 (autoscan.pre): New file.
8279 2002-09-28 Akim Demaille <akim@epita.fr>
8281 * bin/autoscan.in (@kinds): Make them singular.
8282 Adjust all uses.
8283 (&init_tables): When --debug, report the list of rules to ease
8284 tracking changes in autoscan.list.
8285 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8287 2002-09-28 Akim Demaille <akim@epita.fr>
8289 * lib/autoscan/functions, lib/autoscan/headers,
8290 * lib/autoscan/identifiers, lib/autoscan/makevars,
8291 * lib/autoscan/programs: Merge into...
8292 * lib/autoscan/autoscan.list: this.
8293 * bin/autoscan.in (&init_tables): Adjust.
8295 2002-09-28 Akim Demaille <akim@epita.fr>
8297 * lib/autoscan/functions, lib/autoscan/headers,
8298 * lib/autoscan/identifiers, lib/autoscan/makevars,
8299 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8300 `functions' line is now prefixed with `function:'.
8301 * bin/autoscan.in (&init_tables): Adjust.
8303 2002-09-28 Akim Demaille <akim@epita.fr>
8305 From now on, autoscan files must always map a macro name to a
8306 word: there is no `default' macro for autoscan.
8308 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8309 all.
8310 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8311 explicit.
8313 2002-09-28 Akim Demaille <akim@epita.fr>
8315 * bin/autoscan.in (%c_keywords): Remove.
8316 (&used): Keep only track of the words we might be interested in.
8317 (&output_kind): It is no longer needed to look for non active
8318 checks.
8320 2002-09-27 Akim Demaille <akim@epita.fr>
8322 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

8327 2002-09-27 Akim Demaille <akim@epita.fr>
8329 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
8330 from /tmp.
8331 Thanks to Bill Moseley and Paul Eggert.
8332 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8333 the tmpdir must be created.
8334 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8335 dir be in the build tree, instead of $TMPDIR.
8337 2002-09-27 Akim Demaille <akim@epita.fr>
8339 * bin/autoscan.in: Improve the comments.
8340 (&parse_args): Drop obsolete undocumented options.
8341 (&output_kind): Output warnings.
8342 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

8348 Reported by Ralf Corsepius.
8349 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8351 2002-09-26 Akim Demaille <akim@epita.fr>
8353 Single suffix rules and seperated dependencies are not portable.
8355 * doc/autoconf.texi (Installation Directory Variables): Update.
8356 (Limitations of Make): Some about `Single Suffix Rules and
8357 Separated Dependencies'.
8358 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8359 (ifnames, autoscan, autom4te): Un-factor into several rules.
8361 2002-09-25 Paul Eggert <eggert@twinsun.com>
8363 * BUGS (Interoperability bugs): New section. Mention libtool
8364 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8366 2002-09-24 Paul Eggert <eggert@twinsun.com>
8368 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8369 make handles suffix-rules differently from GNU make.
8371 * bin/Makefile.am (SUFFIXES, .in): Remove.
8372 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8373 Move the body of the old .in rule here.
8375 2002-09-16 Akim Demaille <akim@epita.fr>
8377 i960 compilers create `b.out' files by default.
8378 Reported by Ralf Corsepius.
8380 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8381 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8383 2002-09-13 Paul Eggert <eggert@twinsun.com>
8385 * doc/autoconf.texi (Particular Headers): Remove obsolete
8386 reference to `struct timezone' in the description of
8387 AC_HEADER_TIME.
8389 2002-09-13 Akim Demaille <akim@epita.fr>
8391 Version 2.54.
8393 * config/config.sub, config/config.guess: Update.
8394 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8395 * Makefile.am: Adjust.
8397 2002-09-13 Akim Demaille <akim@epita.fr>
8399 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8400 reading config.log when the compiler is rejected.
8401 Suggested by Guido Draheim.
8403 2002-09-13 Akim Demaille <akim@epita.fr>
8405 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8406 (chdir_init) might hang when stat'ing mounted directories.
8407 Reported by Vance Shipley.
8409 2002-09-12 Akim Demaille <akim@epita.fr>
8411 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8412 the lists.
8414 2002-09-12 Akim Demaille <akim@epita.fr>
8416 * doc/autoconf.texi (Defining Symbols): Present two different
8417 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8418 difference between 1 argument calls, and 2-3 argument calls.
8420 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8422 * doc/autoconf.texi: Review grammar and punctuation.
8424 2002-09-11 Paul Eggert <eggert@twinsun.com>
8426 * doc/autoconf.texi: Fix minor formatting, spelling, and
8427 grammatical typos.
8428 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8429 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8430 is obsolescent.
8432 2002-09-11 Akim Demaille <akim@epita.fr>
8434 * doc/autoconf.texi (Questions): Rename as...
8435 (FAQ): this.
8436 (Defining Directories): New.
8438 2002-09-09 Akim Demaille <akim@epita.fr>
8440 * doc/autoconf.texi (Making testsuite Scripts): Update.
8441 Suggested by Nishio Futoshi.
8443 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8445 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8446 plain `@' is wanted.
8448 2002-09-09 Akim Demaille <akim@epita.fr>
8450 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8451 `duplicates', since the algorithm was too naive and could keep
8452 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8453 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8454 Reported by Ralf Corsepius.
8455 * tests/torture.at (Configuring subdirectories): Exercise these
8456 cases.
8458 2002-09-09 Akim Demaille <akim@epita.fr>
8460 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8461 looking for a replacement file.
8462 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8463 directory is relative.
8464 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8465 directory definition.
8466 Reported by Andreas Schwab and Jim Meyering.
8468 2002-09-06 Akim Demaille <akim@epita.fr>
8470 * doc/autoconf.texi (Setting Output Variables): Clarify what
8471 precious variables are.
8472 Suggested by Pontus Skoeld.
8474 2002-09-05 Akim Demaille <akim@epita.fr>
8476 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8477 (ifnames, autoscan, autom4te): Since we don't only depend on
8478 configure.ac variables (such as VERSION etc.), but also on prefix
8479 and so forth, depend on Makefile, not configure.ac.
8480 Reported by Alexandre Duret-Lutz.
8481 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8483 2002-09-05 Kevin Ryde <user42@zip.com.au>
8485 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8486 doesn't seem to be confined to ia64, just say "some versions".
8488 2002-09-04 Akim Demaille <akim@epita.fr>
8490 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8491 Automake 1.6c.
8492 * Makefile.am (maintainer-clean-local): Remove.
8493 (MAINTAINERCLEANFILES): Remove COPYING.
8495 2002-09-03 Paul Eggert <eggert@twinsun.com>
8497 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8498 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8499 Brinkmann.
8501 2002-09-03 Akim Demaille <akim@epita.fr>
8503 * configure.ac: Bump to 2.53d.
8504 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8505 as of today, on Automake's team suggestion.
8507 2002-09-03 Akim Demaille <akim@epita.fr>
8509 Version 2.53c.
8511 2002-09-02 Akim Demaille <akim@epita.fr>
8513 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8514 SITE_MACRO_DIR.
8515 * configure.ac: Disable SITE_MACRO_DIR.
8517 2002-09-02 Jim Meyering <meyering@lucent.com>
8519 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8520 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8521 Also, tweak grammar: s/make sure to/be sure to/.
8523 2002-09-02 Paul Eggert <eggert@twinsun.com>
8525 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8526 directory names are generally preferable to physical names.
8528 2002-09-02 Akim Demaille <akim@epita.fr>
8530 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8531 Reported by Raja R. Harinath.
8532 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8533 * bin/autoupdate.in: Use error instead of die.
8535 2002-09-01 Paul Eggert <eggert@twinsun.com>
8537 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8538 ordinary shell concatenation rather than echo+tr+sed command that
8539 runs afoul of a long-line-related sed bug in Solaris 8.
8541 * bin/autoheader.in (parse_args): --warning -> --warnings.
8543 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8544 stdout, as traditional "ls" does.
8545 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8546 _AC_COMPILER_EXEEXT_O): Likewise.
8547 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8549 * bin/autoconf.as: Add --prepend-include option. This patch was
8550 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8551 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8553 * bin/autoconf.in, configure: Regenerate.
8555 * doc/autoconf.texi (Special Shell Variables): Mention
8556 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8558 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8559 MAILPATH and set PS1, PS2, PS4 to default values, to work
8560 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8561 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8562 the Autoconf documentation specifies; fall back to "unset" only if
8563 this fails. Use a shell for-loop for this rather than an m4 loop,
8564 to shorten the output script.
8566 2002-08-30 Paul Eggert <eggert@twinsun.com>
8568 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8569 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8570 for the CDPATH problem. Document PWD.
8571 (Limitations of Builtins): Document the problem that "cd $foo" and
8572 "ls $foo" may refer to different directories in shells conforming
8573 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8574 example, since the old example is now out of date.
8576 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8577 FOO" and "ls FOO" talk about different directories; this catches
8578 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8579 spaghetti.
8581 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8582 of rolling our own unset.
8583 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8584 in practice we needn't worry about CDPATH if unset doesn't work.
8586 * Makefile.in, aclocal.m4, bin/Makefile.in,
8587 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8588 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8589 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8590 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8591 tests/Makefile.in: Regenerate with Automake 1.6.3.
8593 * config/config.guess, config/config.sub, config/mkinstalldirs:
8594 Update.
8596 * configure: Regenerate with self.
8598 2002-08-30 Kevin Ryde <user42@zip.com.au>
8600 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8601 default output.
8603 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8605 * bin/autom4te.in (Request::load): Correctly test for "do" read
8606 failure.
8608 2002-08-29 Akim Demaille <akim@epita.fr>
8610 * lib/Autom4te/General.pm (&xqx): New.
8611 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8612 hand, which is not portable.
8613 (&error): New.
8614 * bin/autom4te.in: Use them.
8615 Use &error instead of die.
8616 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8617 Adjust.
8619 2002-08-17 Paul Eggert <eggert@twinsun.com>
8621 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8622 default list of compilers to try, since it was long ago superseded
8623 by the ksh fc builtin. Suggested by Steven G. Johnson.
8625 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8627 * doc/autoconf.texi (Invoking autom4te): End the option table,
8628 fixing a bug introduced by the previous patch.
8629 (Limitations of Make): Add a 'target lookup' subentry in the
8630 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8632 2002-07-29 Mark D. Roth <roth@feep.net>
8634 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8635 options and use $AUTOM4TE_PATH.
8636 * doc/autoconf.texi: Remove documentation of autom4te
8637 --include-envvar and --site-macro-subdir options and document
8638 use of $AUTOM4TE_PATH.
8639 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8640 arguments from each language section.
8642 2002-07-29 Paul Eggert <eggert@twinsun.com>
8644 * doc/install.texi: Include copyright symbol in copyright notice.
8646 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8647 Replace with:
8648 (AM_MAKEINFOFLAGS): New macro.
8649 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8650 * Makefile.am (INSTALL): Use the new macros.
8651 Use -o rather than --output, since "missing" does not grok --output.
8653 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8655 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8656 comments do not always work. Never trust the exit status of
8657 `make -k'.
8659 2002-07-24 Kevin Ryde <user42@zip.com.au>
8661 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8662 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8664 2002-07-23 Paul Eggert <eggert@twinsun.com>
8666 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8667 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8668 apparently treats PATH="nonexistent" as if it contained ".".
8669 Bug reported by Stefan `Sec' Zehl.
8671 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8673 * doc/autoconf.texi (Limitations of Make): Mention the special
8674 handling of the obj/ directory by BSD make.
8676 2002-07-20 Kevin Ryde <user42@zip.com.au>
8678 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
8679 backslashes.
8681 2002-07-19 Akim Demaille <akim@epita.fr>
8683 * doc/autoconf.texi (Function Portability): `exit'.
8684 (Programming in M4sh): Ethymology of M4sh.
8686 2002-07-19 Akim Demaille <akim@epita.fr>
8688 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
8690 2002-07-18 Akim Demaille <akim@epita.fr>
8692 Version 2.53b.
8694 2002-07-18 Akim Demaille <akim@epita.fr>
8696 * config/config.guess, config/config.sub: Update.
8698 2002-07-18 Akim Demaille <akim@epita.fr>
8700 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
8701 Automake's parts.
8703 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
8704 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
8705 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
8707 2002-07-18 Akim Demaille <akim@epita.fr>,
8708 Alexandre Duret-Lutz <duret_g@epita.fr>
8710 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
8711 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
8713 2002-07-17 Russ Allbery <rra@stanford.edu>

8716 description of the tarname default.
8718 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
8720 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
8721 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
8722 latter was not run.
8724 2002-07-17 Akim Demaille <akim@epita.fr>
8726 * lib/Autom4te/General.pm (find_file): Browse the directories in
8727 the order they are given.
8729 2002-07-17 Akim Demaille <akim@epita.fr>
8731 * tests/wrapsh.as, tests/wrappl.as: Merge into...
8732 * tests/wrapper.as: this.
8733 * tests/Makefile.am, configure.ac: Adjust.
8735 2002-07-17 Mark D. Roth <roth@feep.net>
8737 * configure.ac: Add --enable-site-macro-dir option.
8738 * bin/Makefile.am: Expand @SITE_MACRO_DIR@.
8739 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
8740 --site-macro-subdir options.
8741 * bin/autoconf.in: Add --prepend-include option.
8742 * bin/autoheader.in: Add --prepend-include option.
8743 * bin/autoreconf.in: Add --prepend-include option.
8744 * bin/autoscan.in: Add --prepend-include option.
8745 * bin/autoupdate.in: Add --prepend-include option.
8746 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
8747 macro directory, remove note that include path directories are
8748 used in reverse order, and document --prepend-include option.
8749 * lib/autom4te.in: Use --prepend-include instead of --include.
8750 * tests/wrapsh.in: Use --prepend-include instead of --include.
8752 2002-07-17 Akim Demaille <akim@epita.fr>
8754 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): `_' is allowed in

8795 2002-06-27 Paul Eggert <eggert@twinsun.com>
8797 * config/install-sh: Quote $src. Prefer || to test's -o option,
8798 as per "Limitations of Builtins".

8830 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>

8860 2002-06-07 Akim Demaille <akim@epita.fr>
8862 * bin/autom4te.in (warn_forbidden): When rejecting a token,

8927 2002-05-22 Paul Eggert <eggert@twinsun.com>
8929 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
8930 from the default list of compilers to try. Suggested by
8931 Kate Hedstrom.
8932 * NEWS: Document the above.
8933 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
8935 2002-05-17 Paul Eggert <eggert@twinsun.com>
8937 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
8938 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
8939 This improves on an earlier suggestion by H. Peter Anvin.
8941 2002-05-16 Paul Eggert <eggert@twinsun.com>
8943 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
8944 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
8945 Both macros now accept an optional source-dir arg.
8946 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
8948 * NEWS: Document this.
8949 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
8951 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
8952 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
8953 not for GNU extensions; this undoes part of the 2000-11-03 change,
8954 reverting to 2.13-compatible behavior.
8955 Add new optional argument DIR.
8956 (AC_FUNC_FNMATCH_GNU): New macro.
8958 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
8960 2002-05-08 Paul Eggert <eggert@twinsun.com>
8962 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
8963 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
8964 and it causes a 'test' syntax error if it fails.
8965 Bug reported by Stephen Gildea.
8967 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8968 If prototypes are supported, use them to check this at compile-time,
8969 instead of trying to check it at run-time. If we must do a run-time
8970 check, assume that setvbuf is standard when cross-compiling, as
8971 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8972 Bug reported by Paul D. Smith.
8974 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8975 argument specifying location of getloadavg.c. This removes a
8976 FIXME. This idea was taken from Jim Meyering's implementation in
8977 textutils.
8978 * doc/autoconf.texi (Particular Functions): Document this.
8979 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8980 that's what the code does; this fixes a bug reported by
8981 Paul D. Smith.
8983 2002-05-03 Akim Demaille <akim@epita.fr>
8985 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8986 autopoint instead of gettextize.
8987 ($uses_alocal): Rename as...
8988 ($uses_aclocal): this.
8989 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8990 Suggested by Bruno Haible.
8992 2002-05-03 Akim Demaille <akim@epita.fr>
8994 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
8996 2002-04-29 Paul Eggert <eggert@twinsun.com>
8998 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
8999 files to be 1 second older; just set them to be the same time.
9000 Also, sleep 1 second after the first aclocal, to work around
9001 problems with sub-second time stamps on the input files.
9003 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9005 * doc/autoconf.texi: Mention "set -e -x" lossage
9006 under node "Limitations of Builtins".
9008 2002-04-29 Akim Demaille <akim@epita.fr>
9010 * doc/install.texi: Better wording for setting variables when
9011 running configure.
9012 From Christian Cornelssen.
9014 2002-04-29 Akim Demaille <akim@epita.fr>
9016 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9017 of lack of $LINENO support, then the test will compare the $LINENO
9018 in testsuite vs. the lineno in the test file. This is wrong, of
9019 course.
9020 Be sure to protect it.
9021 Reported by Patrick Welche.
9023 2002-04-25 Akim Demaille <akim@epita.fr>
9025 * doc/autoconf.texi (Obsolete Macros): Typo.
9026 Reported by Vladimir Volovich.
9028 2002-04-25 Akim Demaille <akim@epita.fr>
9030 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9031 than some of the input files, hence, on the second run of aclocal,
9032 if some of its input are younger, make them older.
9033 Suggested by Paul Eggert.
9035 2002-04-25 Akim Demaille <akim@epita.fr>
9037 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9038 Thanks to Paul Eggert.
9040 2002-04-25 Akim Demaille <akim@epita.fr>
9042 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9043 and ac_subst_vars be sh variables containing the list of
9044 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9045 DEFAULT diversion.
9046 (_AC_INIT_PREPARE): Use them to log them.
9047 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9048 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9049 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9050 _AC_SUBST_FILES and _AC_SUBST_VARS.
9051 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9053 2002-04-24 Akim Demaille <akim@epita.fr>
9055 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9056 autoheader, so that automake does not complain about a missing
9057 config.h.in that was to be created.
9059 2002-04-23 Akim Demaille <akim@epita.fr>
9061 * bin/autoheader.in (parse_args): --warning takes an argument.
9062 Fixes PR/220.
9064 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
9066 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

9113 * doc/autoconf.texi: Follow the outline suggested in the GNU
9114 Sample Texts sections of the Texinfo 4.2 manual. Most
9115 importantly, this makes sure that the copyright notices appear in
9116 all output formats. You probably need Texinfo 4.2 to generate
9117 the manual now.

9145 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

9173 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

9222 Don't use the KILL diversion, as it kills spurious output, which
9223 results in failures being hidden.

9242 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
9243 (_AC_COMPILER_EXEEXT_REJECT): New.
9244 Also recognize *.bb and *.bbg as compilation byproducts.
9245 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9246 (_AC_COMPILER_OBJEXT): Use them.
9247 Fixes Debian #138666.
9249 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9251 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
9253 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
9254 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9255 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9256 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9257 (AC_C_CONST): Same.
9258 (AC_C_INLINE): Same.
9259 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
9260 * doc/autoconf.texi, NEWS: Document.
9261 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
9262 AC_C_CROSS.
9264 2002-04-02 Akim Demaille <akim@epita.fr>
9266 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
9267 _AS_MKDIR_P_PREPARE.
9269 2002-03-28 Kevin Ryde <user42@zip.com.au>
9271 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9272 to avoid versions of HP C which don't allow that.
9274 2002-03-27 Paul Eggert <eggert@twinsun.com>
9276 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9277 (AS_SHELL_SANITIZE): Invoke it.
9278 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9280 2002-03-26 Akim Demaille <akim@epita.fr>
9282 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9284 2002-03-26 Akim Demaille <akim@epita.fr>
9286 * doc/autoconf.texi (Introduction): The GNATS base moved.
9288 2002-03-25 Paul Eggert <eggert@twinsun.com>
9290 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9291 as POSIX requires, as it doesn't work with Zsh.
9292 * doc/autoconf.texi (Assignments): Document the problem.
9294 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9296 * doc/autoconf.texi (Limitations of Make): Mention more issue
9297 about VPATH, overriding of macros in sub-makes, and handling of
9298 SHELL.
9300 2002-03-21 Paul Eggert <eggert@twinsun.com>
9302 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9303 problem with here-document buffer boundaries.
9305 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9306 when reinvoking the shell, to work around problems with installers
9307 who put strange things like "cd" commands in their environments.
9309 2002-03-19 Akim Demaille <akim@epita.fr>
9311 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9312 From Aaron Ucko.
9314 2002-03-19 Akim Demaille <akim@epita.fr>
9316 * bin/autoscan.in (scan_file): Specify the location in `&used'
9317 invocations.
9318 From Nicolas Joly.
9320 2002-03-19 Akim Demaille <akim@epita.fr>
9322 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9323 From Nishio Futoshi.
9325 2002-03-19 Akim Demaille <akim@epita.fr>
9327 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9329 2002-03-18 Paul Eggert <eggert@twinsun.com>
9331 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9332 (Limitations of Usual Tools): Add mkdir section.
9334 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9335 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9336 back on AS_DIRNAME to compute prefixes otherwise; this is
9337 roughly what mkinstalldirs does. That way, we need not have
9338 our own filename disassembler. The old disassembler did not
9339 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9341 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9342 Create at_test_all by a series of assignments,
9343 not by a single assignment of a long string. The latter causes ksh
9344 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9345 presumably because of a buffer overrun.
9347 2002-03-14 Paul Eggert <eggert@twinsun.com>
9349 * lib/autotest/general.m4 (at_times_skip):
9350 Renamed from at_times. Now a boolean.
9351 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9352 says 'times: not found'.
9354 2002-03-14 Akim Demaille <akim@epita.fr>
9356 * bin/autoreconf.in (&study_gettextize): New.
9357 (&autoreconf): Handle newest gettextize.
9358 Rerun aclocal if needed.
9359 Suggested by Andreas Schwab.
9361 2002-03-13 Akim Demaille <akim@epita.fr>
9363 * doc/autoconf.texi (Special Shell Variables): More about IFS.
9365 2002-03-13 Akim Demaille <akim@epita.fr>
9367 * doc/autoconf.texi (Header Portability): New.
9368 Add information about stdint.h and inttypes.h from Paul Eggert.
9370 2002-03-13 Akim Demaille <akim@epita.fr>
9372 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9373 -p'.
9374 From Bob Proulx.
9376 2002-03-12 Akim Demaille <akim@epita.fr>
9378 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9379 m4_require.
9381 2002-03-11 Andreas Schwab <schwab@suse.de>
9383 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9384 does not do it if --with-lispdir is given.
9386 2002-03-08 Akim Demaille <akim@epita.fr>
9388 Version 2.53.
9390 2002-03-08 Akim Demaille <akim@epita.fr>
9392 * doc/autoconf.texi (Subdirectories): Clarify that the
9393 subdirectory should exist.
9395 2002-03-08 Akim Demaille <akim@epita.fr>
9397 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9399 2002-03-08 Akim Demaille <akim@epita.fr>
9401 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9402 aliases the actual variables, and modifications of the former
9403 affect the latter.
9405 2002-03-08 Akim Demaille <akim@epita.fr>
9407 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9408 because of C-c: have m4 output in tmp files, then mv them.
9410 2002-03-08 Akim Demaille <akim@epita.fr>
9412 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9413 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
9414 * bin/ifnames.in: Copyright update.
9416 2002-03-08 Akim Demaille <akim@epita.fr>
9418 * doc/autoconf.texi (Invoking autom4te): New.
9420 2002-03-05 Akim Demaille <akim@epita.fr>
9422 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9423 Kevin Ryde.
9425 2002-03-05 Akim Demaille <akim@epita.fr>
9427 Version 2.52i.
9429 2002-03-04 Akim Demaille <akim@epita.fr>
9431 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9432 * lib/autoconf/general.m4 (AC_INIT): More informative error
9433 message for LIBOBJ.
9435 2002-03-04 Akim Demaille <akim@epita.fr>
9437 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9438 parallel builds.
9440 2002-03-04 Akim Demaille <akim@epita.fr>
9442 * doc/autoconf.texi (Transforming Names): Equality between target
9443 and host is irrelevant.
9444 (Specifying Names, Canonicalizing): Remove all references to the
9445 backward compatibility hooks. Rather, collect them all into...
9446 (Hosts and Cross-Compilation): this new section.
9447 * doc/install.texi (System Type): Ditto.
9448 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9449 that `--host' implies cross-compilation.
9451 2002-03-04 Akim Demaille <akim@epita.fr>
9453 * doc/autoconf.texi (Evaluation Macros): New.
9454 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9455 useless.
9456 (_m4_foreach): Define the variant with immediate evaluation so
9457 that it contains exactly the items, not an expression which
9458 evaluation is the current item.
9459 (m4_re_string, m4_re_word): Don't over quote them.
9461 2002-03-04 Akim Demaille <akim@epita.fr>
9463 Instead of having stacking `shift's evaluated at the end, let
9464 `foreach' loops immediately evaluate them.
9466 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9467 $*. This is the n-th time I change my mind, but hopefully this is
9468 the last...
9469 (m4_lquote): New.
9470 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9471 efficient.
9472 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9473 it was only a hack for m4_text_wrap.
9474 (m4_car2): Remove, replaced by...
9475 (m4_cdr): New.
9476 (_m4_foreach): Adjust.
9477 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9478 m4_bpatsubst for clarification.
9480 2002-03-04 Akim Demaille <akim@epita.fr>
9482 * doc/autoconf.texi (Changequote is Evil): New.
9484 2002-03-03 Kevin Ryde <user42@zip.com.au>
9486 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
9487 on old systems like SunOS.
9489 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
9491 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9492 lib/autoconf/functions.m4, lib/autoconf/general.m4,

9500 message to be sent.
9502 2002-02-28 Kevin Ryde <user42@zip.com.au>

9506 2002-02-25 Akim Demaille <akim@epita.fr>
9508 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
9509 From Akinori Musha.
9511 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
9513 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
9514 translate \r\n to \n.
9516 2002-02-07 Akim Demaille <akim@epita.fr>
9518 Version 2.52h.
9520 2002-02-07 Akim Demaille <akim@epita.fr>
9522 Fix Autoconf PR/209.
9523 Also reported by Frank Denis.
9525 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
9527 2002-02-07 Akim Demaille <akim@epita.fr>
9529 Fix Autoconf PR/207:
9530 AC_PREFIX_PROGRAM fails with dashed program names
9532 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9533 variable when looking for the prefix program.
9534 Now it also works for shell variables.
9536 2002-02-07 Akim Demaille <akim@epita.fr>
9538 * doc/autoconf.texi (Limitations of Builtins): More about
9539 case/esac.
9541 2002-02-06 Akim Demaille <akim@epita.fr>
9543 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
9544 case/esac, some shells don't support it.
9545 Reported by Zack Weinberg.
9546 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
9548 2002-02-06 Akim Demaille <akim@epita.fr>
9550 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9551 sure not to introduce newlines in at_groups.
9552 * lib/autotest/Makefile.am (autotest.m4f): Typo.
9554 2002-02-06 Akim Demaille <akim@epita.fr>
9556 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9557 is not available.
9559 2002-02-05 Paul Eggert <eggert@twinsun.com>
9561 * doc/autoconf.texi (Specific Compiler Characteristics):
9562 Describe HP-UX cc bug workaround more accurately.
9563 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
9564 not unsigned long.
9565 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9566 cross-compilers, too. This undoes some of the most recent change
9567 to this file.
9569 2002-02-05 Akim Demaille <akim@epita.fr>
9571 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9572 to make sure they are up to date when `check' is run.
9574 2002-02-05 Akim Demaille <akim@epita.fr>
9576 * doc/autoconf.texi (Making testsuite Scripts): Document
9577 package.m4.
9579 2002-02-05 Akim Demaille <akim@epita.fr>
9581 * lib/freeze.mk: New.
9583 2002-02-05 Akim Demaille <akim@epita.fr>
9585 Implement `autom4te --freeze'.
9587 * bin/autom4te.in (&freeze): New.
9588 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9589 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9591 2002-02-05 Akim Demaille <akim@epita.fr>
9593 * bin/autom4te.in (&parse_args): Implement `frozen files are
9594 optional are the sum of the previous files on the command line'.
9595 Also, pass `--reload-state=' on them, so...
9596 (handle_m4): don't.
9597 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9598 (M4sh): Rely on M4sugar.
9599 (Autotest, M4sh, M4sugar): Use frozen files.
9601 2002-01-31 Akim Demaille <akim@epita.fr>
9603 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
9604 * doc/autoconf.texi (Initializing configure): Adjust.
9606 2002-01-30 Akim Demaille <akim@epita.fr>
9608 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9609 alphanumeric to `-' instead of `_'.
9611 2002-01-30 Akim Demaille <akim@epita.fr>
9613 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9614 for plain code, the other for cross-compilation code. The latter
9615 is now run with GCC only.
9616 * doc/autoconf.texi (Compilers and Preprocessors): New.
9618 2002-01-30 Akim Demaille <akim@epita.fr>
9620 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
9621 values.
9622 * doc/autoconf.texi (Initializing configure): Explain how to
9623 change AC_INIT default values.
9625 2002-01-29 Akim Demaille <akim@epita.fr>
9627 * tests/torture.at (Configuring subdirectories): Use configure.in,
9628 so that aclocal 1.4 works.
9629 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9631 2002-01-28 Akim Demaille <akim@epita.fr>
9633 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9634 needs an argument.
9636 2002-01-28 Akim Demaille <akim@epita.fr>
9638 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9639 AUTOTEST_PATH *after* it was set.
9640 Don't put `.' in the PATH: the user should be precise and `./' if
9641 needed. In addition, given that the test suite does some `cd', if
9642 `.' is in the path, the `tested programs' sections will report
9643 programs found in the test suite's directory, while during the
9644 tests (performed in their own directory), these programs are no
9645 longer visible. In other words, the results is confusing and
9646 useless.
9647 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9649 2002-01-24 Akim Demaille <akim@epita.fr>
9651 Version 2.52g.
9653 2002-01-24 Akim Demaille <akim@epita.fr>

9656 * doc/autoconf.texi: Finally add Akim as an author.
9658 2002-01-24 Akim Demaille <akim@epita.fr>
9660 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
9661 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
9662 Bourne. Use /bin/sh.
9663 From Andreas Buening.
9665 2002-01-24 Akim Demaille <akim@epita.fr>
9667 * config/config.guess, config/config.sub, config/texinfo.tex:

9676 * config/strip.m4: Remove, to ease sync'ing with any version of
9677 Automake.
9679 2002-01-24 Akim Demaille <akim@epita.fr>
9681 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
9682 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
9683 Reported by Geir Ove Myhr.
9685 2002-01-21 Akim Demaille <akim@epita.fr>
9687 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
9689 2002-01-21 Akim Demaille <akim@epita.fr>
9691 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
9692 message on invalid options.
9693 * bin/autom4te.in (parse_args): Don't use
9694 Autoconf::General::getopt with non valid options.
9696 2002-01-17 Jim Meyering <meyering@lucent.com>
9698 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
9699 $ac_cv_exeext so we don't use an old, invalid, cached value.
9701 2002-01-11 Akim Demaille <akim@epita.fr>
9703 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
9704 Meyering.
9705 * doc/autoconf.texi (Function Portability): Document the strnlen
9706 limitation.

9708 * lib/autoscan/functions: Adjust.
9710 2002-01-06 Akim Demaille <akim@epita.fr>
9712 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
9713 package.m4, since is really depends upon configure.ac, not
9714 configure.
9715 * doc/autoconf.texi (testsuite Scripts): Adjust.
9716 * tests/Makefile.am (package.m4): New.
9717 EXTRA_DIST it since its a source.
9719 2002-01-06 Akim Demaille <akim@epita.fr>
9721 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9722 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9723 and PACKAGE_BUGREPORT from here...
9724 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9725 arguments.
9726 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
9727 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
9728 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
9729 * tests/tools.at (autoheader): Adjust.
9730 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
9732 2002-01-06 Akim Demaille <akim@epita.fr>
9734 * bin/autoscan.in (scan_file): Use `&used'.
9736 2002-01-03 Akim Demaille <akim@epita.fr>
9738 * doc/autoconf.texi (Output): Improved wording regarding use of
9739 AC_OUTPUT.
9740 From Olly Betts.
9742 2001-12-18 Kevin Ryde <user42@zip.com.au>
9744 * doc/autoconf.texi (Function Portability): Add notes on sscanf
9745 sometimes needing writable input.
9747 2001-12-17 Jim Meyering <meyering@lucent.com>
9749 * doc/autoconf.texi (New Macros): Tweak wording.
9751 2001-12-14 Akim Demaille <akim@epita.fr>
9753 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9754 trailing files, don't apply `-rf' to files which might not be
9755 created by configure (core, core.*, and *.core), but just `rm -f'.
9756 Suggested by Jonathan Kamens.
9758 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9760 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
9762 2001-12-14 Akim Demaille <akim@epita.fr>
9764 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
9766 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
9768 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
9769 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
9770 abs_srcdir, top_srcpath to abs_top_srcdir.
9771 (_AC_OUTPUT_FILES): Adjust.
9772 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
9773 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
9774 * tests/wrappl.in, tests/wrapsh.in: Adjust.
9776 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
9778 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
9779 C/Fortran linking on HP/UX, by extracting the Fortran library
9780 search path from the LPATH line in the $F77 -v output.
9782 2001-12-12 Kevin Ryde <user42@zip.com.au>
9784 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
9785 forbidden file descriptors table.
9787 2001-11-26 Akim Demaille <akim@epita.fr>
9789 * bin/autoscan.in (%c_keywords): Build it at top level.
9790 Map to 1 in order to simplify its uses.
9792 2001-11-26 Akim Demaille <akim@epita.fr>
9794 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
9795 Remove $filepath, useless.
9796 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
9797 variables, they are really part of the tokens.
9798 Split the input line on spaces and then look for tokens.
9799 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9800 because of `lex$U.$(OBJEXT)'.
9801 (&scan_files): Use "@list" instead of join.
9802 * doc/Makefile.am (CLEANFILES): Add *.fns.
9804 2001-11-26 Akim Demaille <akim@epita.fr>
9806 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
9807 Remove, replaced by...
9808 * tests/wrappl.in: Be common for all the Perl executables.
9809 In particular autoscan and autoheader want -I.
9810 * configure.ac: Adjust.
9811 * lib/autoscan/headers: errno.h is portable.
9813 2001-11-26 Akim Demaille <akim@epita.fr>
9815 * bin/autoscan.in (used): New.
9816 Use it.
9818 2001-11-26 Akim Demaille <akim@epita.fr>
9820 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
9821 directives.
9822 (&scan_sh_file): Remove a duplicate pattern.
9823 (&check_configure_ac): Use long options.
9824 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
9826 2001-11-26 Akim Demaille <akim@epita.fr>
9828 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
9829 Before, having a line containing the opening of a multi line
9830 comment made the whole line be ignored.
9832 2001-11-26 Akim Demaille <akim@epita.fr>
9834 * doc/autoconf.texi (Using an Autotest Test Suite): New.
9835 (testsuite Scripts): Be one of its subsection.
9836 (Autotest Logs): New.
9838 2001-11-26 Akim Demaille <akim@epita.fr>
9840 Test groups are now run two directories deeper.
9842 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
9843 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
9844 at_top_builddir.
9845 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
9846 top_srcdir, builddir and top_builddir.
9847 Use `at_*dir' relatively to the directory containing the
9848 suite, use `*dir' when relatively to the current group dir.
9850 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
9852 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
9853 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
9854 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
9855 spelling errors.
9857 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9859 * doc/autoconf.texi (Using System Type): Add an example of `case
9860 $host' usage so people quit using `case $target' everywhere.
9862 2001-11-22 Akim Demaille <akim@epita.fr>
9864 * doc/autoconf.texi (Installation Directory Variables): Englishoes
9865 spotted by Jim Meyering.
9867 2001-11-16 Paul Eggert <eggert@twinsun.com>
9869 This patch implements a `long double' suggestion by Oliver Kiddle.
9871 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9872 static, to catch errors if the value isn't known at compile-time
9873 and the compiler supports dynamic arrays. Change its name from
9874 `_array_' to `test_array' to avoid potential name clashes.
9875 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9876 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9877 better than double. Catch a bug in GCC 2.95.2 x86.
9878 * doc/autoconf.texi (C Compiler): Document the above.
9879 * NEWS: Likewise.
9881 2001-11-13 Akim Demaille <akim@epita.fr>
9883 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9884 hand.
9885 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9887 2001-11-13 Akim Demaille <akim@epita.fr>
9889 * lib/autotest/general.m4 (AT_INIT): After having run the test
9890 group, go back to the initial directory, not to at_suite_dir.
9892 2001-11-13 Akim Demaille <akim@epita.fr>
9894 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9895 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9896 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9897 option.
9898 (AT_CHECK_CONFIGURE): Use absolute paths.
9899 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9900 The problem is still the old one: there is no means in M4 (that I
9901 know about) to create a defining macro, because there is no means
9902 to create `$1' etc., therefore, the defining macro ``swallows''
9903 all the arguments meant to the defined macro.
9905 2001-11-13 Akim Demaille <akim@epita.fr>
9907 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9908 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9909 configure.ac.
9910 * tests/aclocal.m4: Remove, as it is no longer used.
9912 2001-11-13 Akim Demaille <akim@epita.fr>
9914 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9915 variable names when referring to a single test group, or to
9916 `suite' when referring to the whole test suite.
9917 `at_last_test' is removed: m4 compute at_format itself.
9918 (at_stdout, at_stder1, at_stderr): New variables.
9919 (AT_CHECK): Use them.
9921 2001-11-13 Akim Demaille <akim@epita.fr>
9923 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9924 in PATH.
9925 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9926 Do it as soon as a test fails, don't wait till the end of the test
9927 suite.
9928 Don't remove $as_me.[0-9]*, since these files no longer exist.
9930 2001-11-13 Akim Demaille <akim@epita.fr>
9932 * tests/tools.at: Use absolute paths, since we are no longer run
9933 in place.
9935 2001-11-13 Akim Demaille <akim@epita.fr>
9937 Now that tests are running in their own private dir, there is no
9938 need to list the files to remove at the end of tests groups.
9940 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
9941 (AT_data_files, at_data_files): Remove.
9942 (AT_CLEANUP, AT_DATA): Simplify.
9943 (AT_INIT): Adjust.
9944 Remove the group dir if !debug && !failed.
9945 * tests/atspecific.m4: Adjust.
9947 2001-11-13 Akim Demaille <akim@epita.fr>
9949 Start a new layout for Autotest: `testsuite' creates
9950 `testsuite.dir' in which the at-check-line etc. files are to be
9951 found, and `testsuite.dir/003' where the test group 3 is run.
9953 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
9954 at_check_line_file, at_format, at_test_normalized, at_group_dir
9955 are new variables.
9956 Create the directories.
9957 Use absolute paths for at- files.
9958 (AT_CHECK): Adjust.
9960 2001-11-11 Michael Matz <matz@kde.org>
9962 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
9963 (m4_car2): New.
9964 (m4_car): Properly quote arguments.
9966 2001-11-13 Akim Demaille <akim@epita.fr>
9968 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9969 with stricter rules on LIBOBJS.
9971 2001-11-12 Paul Eggert <eggert@twinsun.com>
9973 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9974 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9975 __PROTOTYPES too.
9977 2001-11-12 Akim Demaille <akim@epita.fr>
9979 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9981 2001-11-12 Akim Demaille <akim@epita.fr>
9983 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9984 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
9985 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9986 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9987 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9988 specify to what the macro should be defined (typically to 1).
9990 2001-11-12 Akim Demaille <akim@epita.fr>
9992 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9993 From Jim Meyering.
9995 2001-11-12 Akim Demaille <akim@epita.fr>
9997 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9998 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
9999 definition used by Automake where LEX is +/- "${missing} lex" and
10000 `missing' itself contains variables.
10002 2001-11-12 Akim Demaille <akim@epita.fr>
10004 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10005 Now that M4sh pushes BODY, the comments were output at the end of
10006 the test suites.
10008 2001-11-08 Akim Demaille <akim@epita.fr>
10010 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10011 that we can trace macros from aclocal.m4.
10012 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10013 obsoleted, and redirect to the former anyway.
10014 Reported by Ralf Corsepius.
10016 2001-11-08 Akim Demaille <akim@epita.fr>
10018 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10019 processed only if present.
10020 * tests/torture.at (Configuring subdirectories): Use autoreconf
10021 instead of successive calls to autoconf.
10022 Add a nonexistent subdirectory to exercise the patch above.
10023 Reported by Ralf Corsepius.
10025 2001-11-08 Kevin Ryde <user42@zip.com.au>
10027 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10028 doesn't accept .S files.
10030 2001-11-07 Akim Demaille <akim@epita.fr>
10032 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10033 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10034 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10035 * bin/autom4te.in (warn_forbidden): New.
10036 (handle_output): Use it.
10037 Read m4_pattern_forbid with messages.
10039 2001-11-05 Akim Demaille <akim@epita.fr>
10041 * bin/autom4te.in (--normalize): Remove.
10042 * lib/autom4te.in: Adjust.
10044 2001-11-05 Akim Demaille <akim@epita.fr>
10046 * tests/Makefile.am (testsuite): Rename this target as...
10047 ($(TESTSUITE)): this.
10048 From Nicolas Joly.
10050 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10052 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10053 the --prefix option, also remove it's argument.
10055 2001-11-05 Akim Demaille <akim@epita.fr>
10057 * doc/autoconf.texi (testsuite Invocation): Update.
10058 (Writing testsuite.at): Update.
10060 2001-11-03 Akim Demaille <akim@epita.fr>
10062 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10064 2001-11-03 Akim Demaille <akim@epita.fr>
10066 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10067 (&file_name_is_absolute): New, wrappers around routines from
10068 File::Spec.
10069 Use and export them.
10070 (&find_configure_ac): Optionally take a directory where to look at.
10071 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10072 the arguments.
10073 Default @ARGV to `.', not find_configure_ac.
10074 (&autoreconf): Argument is a directory.
10075 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10076 * doc/autoconf.texi (autoreconf Invocation): Update.
10078 2001-11-03 Akim Demaille <akim@epita.fr>
10080 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10081 (@export_forward_subs): New.
10082 Add basename, dirname, and fileparse.
10083 (@EXPORT): Adjust.
10084 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10085 Don't look for aclocal flags if we already know aclocal is not
10086 used.
10087 Move aclocal.m4t only if it exists.
10088 Reported by Ezra Peisach.
10090 2001-11-03 Akim Demaille <akim@epita.fr>
10092 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10093 passed on command line, defaulting to ./configure.ac if present.
10094 (&maybe_autoreconf, File::Find): Remove, unused.
10095 (&autoreconf): If autoconf is not used, don't try to trace.
10097 2001-11-02 Akim Demaille <akim@epita.fr>
10099 * configure.ac: Bump to 2.52g.
10101 2001-11-02 Akim Demaille <akim@epita.fr>
10103 Version 2.52f.
10105 2001-11-02 Akim Demaille <akim@epita.fr>
10107 * config/config.guess, config/config.sub, doc/standards.texi:
10108 * config/lispdir.m4: Update from masters.
10109 * configure.ac: Bump to 2.52f.
10111 2001-11-02 Akim Demaille <akim@epita.fr>
10113 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10114 Don't run aclocal when aclocal.m4 is not from aclocal.
10115 From Ezra Peisach.
10116 Don't run libtoolize and gettextize if --install is not given.
10118 2001-11-01 Paul Eggert <eggert@twinsun.com>
10120 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10121 be invoked before _AS_LINENO_PREPARE.
10122 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10123 than character ranges.
10125 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10126 invoking AS_BASENAME. Set the locale variables to 'C' if
10127 possible, as POSIX requires this to get the traditional
10128 behavior.
10129 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10131 2001-10-31 Paul Eggert <eggert@twinsun.com>
10133 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10134 with {}, as that triggers a bug in Bash 2.05.
10136 (_AS_LINENO_PREPARE): Use Sed rather than
10137 Awk. Fix the sed prepass to work even if there are multiple
10138 instances of $LINENO on the same line. Do not substitute for
10139 other variables like $LINENOT. Do not check file dates; such a
10140 check is unreliable on sufficiently fast machines, and removing
10141 the check makes the code simpler and more reliable. Check for
10142 output and chmod failures.
10144 * doc/autoconf.texi (Special Shell Variables): Document
10145 the above.
10147 2001-10-31 Akim Demaille <akim@epita.fr>
10149 * tests/Makefile.am (atconfig): Remove this target, Automake
10150 handles it now.
10152 2001-10-31 Akim Demaille <akim@epita.fr>
10154 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10155 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10156 provided, while it is optional.
10157 * configure.ac: Adjust.
10159 2001-10-26 Paul Eggert <eggert@twinsun.com>
10161 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10162 lib/Autom4te/Struct.pm:
10163 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10164 with 5.005_02.
10166 * doc/autoconf.texi (Special Shell Variables): Document some
10167 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10169 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10170 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10171 eval $LINENO is not portable in practice.
10173 2001-10-24 Akim Demaille <akim@epita.fr>
10175 * lib/Autom4te/General.pm (backname): New.
10177 2001-10-24 Akim Demaille <akim@epita.fr>
10179 * m4/: Remove, merged into...
10180 * config/: here.
10182 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10184 * doc/autoconf.texi (Shellology): Mention the problems with bash
10185 2.05's use of ANSI quoting in its `set' builtin.
10187 2001-10-22 Paul Eggert <eggert@twinsun.com>
10189 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10190 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10191 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10192 POSIX decided to standardize on the int flavor of strerror_r.
10193 Always do char* test, as there's no reason not to.
10194 Assign to a char* var, to catch strerror_r that returns int*.
10196 * doc/autoconf.texi (Particular Functions):
10197 Document the above changes. Also, document the fact that
10198 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10200 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10202 2001-10-20 Akim Demaille <akim@epita.fr>
10204 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10205 the executable was missing from the log.
10207 2001-10-20 Akim Demaille <akim@epita.fr>
10209 * lib/Autom4te/General.pm (&update_file): If destination is
10210 unchanged, remove the source.
10211 (&up_to_date_p): Don't be verbose, be debug.
10212 * bin/autoreconf.in: No longer support --m4dir.
10213 (&autoreconf): Display the full path of the configure.ac we are
10214 studying.
10215 Trace it only once.
10216 Be sure to honor --force with gettextize.
10217 Always run aclocal.
10218 * doc/autoconf.texi: Adjust.
10220 2001-10-20 Akim Demaille <akim@epita.fr>
10222 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10223 Remove, dead.
10224 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10225 `intl' is already present, as it refuses unless --force.
10226 (&parse_args): Use -I, --include instead of the old Autoconf

10504 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

10678 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10680 * lib/autoconf/general.m4: Fix a small Englisho.
10681 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
10682 setting up ac_dir_suffix and ac_top_builddir.
10683 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
10685 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10687 * doc/autoconf.texi (File System Conventions): Clarify the use of
10688 PATH_SEPARATOR.
10689 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
10690 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
10691 be used instead of ':'.
10692 * lib/autotest/general.m4: Replace occurrences of ':' in
10693 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
10695 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10697 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
10698 arguments. Fixed a typo.
10700 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10702 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
10703 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
10705 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10707 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
10708 * bin/autoupdate.in: Ditto.
10709 * bin/autoheader.in: Reworded a few comments.
10710 * bin/autoconf.in: Reworded help text for a few options.
10711 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10712 * bin/autoscan.in, bin/autoupdate.in: Ditto.
10714 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10716 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10717 already have $file). Set output files to binary mode (helps avoid
10718 CR issues on DOSish systems).
10720 2001-09-19 Akim Demaille <akim@epita.fr>
10722 * lib/autotest/general.m4: Englishoes.
10723 From Tim Van Holder and Alexey Mahotkin.
10725 2001-09-18 Paul Eggert <eggert@twinsun.com>
10727 * doc/autoconf.texi (Common Shell Constructs): New node,
10728 documenting AS_DIRNAME.
10729 (Limitations of Usual Tools): Refer to it when discussing dirname.
10730 Also, update discussion of POSIX standard to reflect latest draft.
10732 * lib/autoconf/c.m4:
10733 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
10735 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10736 Do not pass a first argument with leading '-'
10737 to expr, by parenthesizing initial integers that might be negative.
10739 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10740 now merely checks whether it is an error to pass an argument
10741 to getpgrp.
10743 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10744 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
10745 whether it is a (compile-time) error to pass an argument to
10746 getpgrp. This simpler test supports the revised documentation,
10747 and is all that AC_FUNC_GETPGRP's users really need.
10749 2001-09-18 Akim Demaille <akim@epita.fr>
10751 * doc/autoconf.texi (Limitations of Make) <$<>: New.
10753 2001-09-18 Akim Demaille <akim@epita.fr>
10755 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
10756 `{}'.
10757 * lib/autotest/general.m4 (AT_INIT): Adjust.
10759 2001-09-18 Paul Wagland <paul@wagland.net>
10761 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
10762 correctly.
10763 Add test for AS_BASENAME.
10764 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10765 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10766 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10767 * tests/base.at: Fixed the expected responses. The old ones were
10768 one line out...
10769 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10770 the documentation claims it should (and how it behaved in 2.13).
10772 2001-09-18 Akim Demaille <akim@epita.fr>
10774 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
10775 the AC_CONFIG_COMMANDS invocation.
10776 This also solves the name clash problems.
10777 Don't set the package's ID.
10778 * lib/m4sugar/Makefile.am (version.m4): Revamp.
10779 No longer to be shipped.
10780 (version.in): Remove.
10781 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
10782 * lib/autoconf/status.m4: Adjust.
10783 Use `m4_PACKAGE_STRING'.
10784 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
10785 the only optional argument is the name of the test suite.
10786 Expect `package.m4' to define the package signature.
10787 * lib/autom4te.in (Autotest): Add `package.m4?'.
10788 * tests/Makefile.am (package.m4): New.
10789 * tests/suite.at: ifnames is a victim.
10791 2001-09-18 Akim Demaille <akim@epita.fr>
10793 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
10794 AC_LIBSOURCE, AC_CONFIG_FILES.
10795 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
10796 program version string doesn't match the package's.
10797 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
10798 after `(cached)'.
10800 2001-09-17 Paul Eggert <eggert@twinsun.com>
10802 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10803 Allow expression to return any value that can fit into unsigned long
10804 (not int, as before). Check for output errors.
10806 2001-09-17 Bruno Haible <haible@ilog.fr>
10808 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10809 Always include <stdio.h> and <stdlib.h>. Evaluate
10810 the expression in an extra function before these includes. Call
10811 fprintf "%d" only after ensuring the argument is of type 'int'.
10812 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
10814 2001-09-17 Paul Eggert <eggert@twinsun.com>
10816 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10817 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10818 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10819 when they don't exist.
10821 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
10822 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
10823 need it.
10825 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
10826 version with the version used by fileutils 4.1, except use
10827 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
10828 we don't need it.
10830 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
10832 2001-09-13 Akim Demaille <akim@epita.fr>
10834 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
10835 _first_.
10836 Reported by Gerrit P. Haase.
10838 2001-09-13 Akim Demaille <akim@epita.fr>
10840 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
10841 m4_defn'ing is valid.

10847 Use it.

10855 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
10856 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
10857 Likewise.
10858 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)

10860 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
10861 AT_tests_all for consistency.
10862 Set at_victims.
10863 (AT_VICTIMS): Similar to AT_KEYWORDS.
10864 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
10866 2001-09-13 Akim Demaille <akim@epita.fr>
10868 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
10870 2001-09-13 Akim Demaille <akim@epita.fr>
10872 * lib/autotest/general.m4 (AT_INIT): Create and remove
10873 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
10874 test suites can cohabit.
10876 2001-09-13 Akim Demaille <akim@epita.fr>
10878 * tests/mktests.sh: Don't output banners for empty test files.
10880 2001-09-13 Akim Demaille <akim@epita.fr>
10882 Test suites can be run independently of configure.
10884 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
10885 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.

10928 2001-09-10 Akim Demaille <akim@epita.fr>
10930 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

10963 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
10964 in addition, it introduces useless differences in logs.

10966 Adjust PATH computation.
10967 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

10982 * bin/autom4te.in: --language is -l, not -s.
10984 2001-09-05 Akim Demaille <akim@epita.fr>
10986 Be ready to handle filenames as stupid as `dnl.at', for if even
10987 the maintainer is dumb enough to do that...
10989 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
10990 excellence in M4 quotation: consider `__file__' is active.
10992 And BTW, when invoking m4, pass the --include in the right order:

11023 New, extracted from main.
11024 Use IO::File wherever possible.
11025 (input.m4): Be constant, use -I instead of hard coding $tmp.
11026 Therefore be a quoted heredoc.
11027 Don't invoke `_au_disable', since ac was not loaded, but just
11028 `unm4.m4'.
11030 2001-08-31 Akim Demaille <akim@epita.fr>
11032 Version 2.52d.

11053 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
11055 2001-08-31 Akim Demaille <akim@epita.fr>
11057 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11058 (testsuite Scripts): There is no such thing as `atconfig.in'.

11061 2001-08-31 Akim Demaille <akim@epita.fr>
11063 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

11069 to m4sugar was lacking!
11071 2001-08-31 Akim Demaille <akim@epita.fr>
11073 * man/Makefile.am (.x.1): We really have to pass
11074 autom4te_perllibdir.
11076 2001-08-31 Akim Demaille <akim@epita.fr>
11078 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11079 debug scripts, in particular passing explicitly listed tests to
11080 run is stupid.
11082 2001-08-31 Akim Demaille <akim@epita.fr>
11084 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11085 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11086 Use directly autom4te, not autoconf.

11109 * bin/autom4te.in ($autoconf): Pass --force.
11110 `print $out' doesn't print `$_' but `$out'.
11111 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11112 (autoheader): Pass --force since the test suite goes too fast for
11113 the time stamps.
11114 Adjust to the new autoheader messages.
11116 2001-08-31 Akim Demaille <akim@epita.fr>

11129 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11130 `autoheader: `config.hin' is created'.
11131 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11133 2001-08-31 Akim Demaille <akim@epita.fr>
11135 * bin/autoheader.in: Rewrite in Perl.
11136 * tests/autoheader: Adjust.
11138 2001-08-31 Akim Demaille <akim@epita.fr>
11140 * bin/autoconf.in (--include, -I): New option.
11141 Map --localdir, --autoconf-dir onto it.
11142 Forward autom4te's options instead of interpreting them.
11143 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11144 There is no such envvar since the inception of autom4te.cfg.
11145 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11146 * bin/autoupdate.in: Adjust, and perform more control.
11147 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
11148 * tests/autoconf: Dittowise.
11150 2001-08-31 Akim Demaille <akim@epita.fr>
11152 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11153 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11154 optionally `FILE'.
11155 Use -e, not -f, since /dev/null for instance is OK.
11156 (&parse_args): Adjust.
11157 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11159 2001-08-31 Akim Demaille <akim@epita.fr>
11161 * configure.ac: Also find tested executables in bin.
11162 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11163 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11164 installed peer executables, only PATH is allowed to resolve it.
11165 Pass `autoconf_dir' via options, not via invisible envvars.
11166 * lib/Autom4te/General.pm (&find_peer): Remove.
11167 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11168 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11169 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11170 find the executables for it.
11171 * tests/Makefile.am: Major cleanup. Too lazy to document...
11172 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11173 We only need PERL.
11174 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11175 indeed related to running the test suite, while passing
11176 --autoconf-dir and others is related to running non installed
11177 Autoconf executables. So don't do that, leave it to...
11178 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11179 * tests/autoscan: New.
11180 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11181 refer to library files: rely on --language.
11183 2001-08-29 Akim Demaille <akim@epita.fr>
11185 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
11186 s/--set/--language/.
11188 2001-08-29 Akim Demaille <akim@epita.fr>
11190 * doc/autoconf.texi: Strip the @nodes.
11191 Suggested by Paul Eggert.
11192 (Initializing configure): Typo.
11194 2001-08-29 Akim Demaille <akim@epita.fr>
11196 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11197 Suggested by Paul Eggert.
11199 2001-08-29 Akim Demaille <akim@epita.fr>
11201 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11202 download in a tmp dir.
11204 2001-08-29 Akim Demaille <akim@epita.fr>
11206 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
11207 case insensitive OSes out there :(
11208 From Tim Van Holder.
11210 2001-08-29 Akim Demaille <akim@epita.fr>
11212 * lib/autom4te.in: New.

11214 * bin/autom4te.in (BEGIN): Simplify.
11215 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
11216 (&load_configuration): New. Use it.
11217 (&parse_args): Support --mode, --set, and --melt.
11218 * bin/autoconf.in: Simplify and adjust.
11219 * tests/Makefile.am (AUTOMAKE): Use --set.
11220 * tests/atlocal.in: Adjust.
11221 * BUGS: distcheck and check are weak.
11223 2001-08-29 Akim Demaille <akim@epita.fr>
11225 * lib/autotest/general.m4: Use
11226 foo=`(command) 2>/dev/null`
11227 not
11228 foo=`command` 2>/dev/null
11229 (at-devnull): Rename as...
11230 (AT-devnull): this.
11231 (--clean): Remove AT-* files too.
11232 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
11233 Reported by Nicolas Joly.
11235 2001-08-28 Akim Demaille <akim@epita.fr>
11237 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

11239 Reported by Nicolas Joly.
11241 2001-08-28 Kevin Ryde <user42@zip.com.au>
11243 * doc/autoconf.texi (Function Portability): Mention C right shifts.
11245 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
11247 * lib/autotest/general.m4: Reword some messages.
11248 (AT_INIT): Check for the `times' builtin before using it.
11249 Support test ranges as arguments to the testsuite.
11250 Have -e imply -d as the help text suggested.
11252 2001-08-27 Akim Demaille <akim@epita.fr>
11254 * Makefile.maint: Formatting changes.
11255 (do-po-update, po-update, cvs-update, update): New targets.

11267 * lib/autotest/general.m4 (AT_INIT): Log the command line.
11268 Support `VAR=VAL' as arguments.
11269 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
11270 may be set via the command line.
11272 2001-08-27 Akim Demaille <akim@epita.fr>
11274 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
11275 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
11276 first the build dirs, then the src dirs.

11279 2001-08-27 Akim Demaille <akim@epita.fr>
11281 * lib/autotest/general.m4 (AT_INIT): Output the definition of
11282 at_data_files earlier.
11283 (--clean, -c): New option.
11284 * tests/Makefile.am: Use this option.
11286 2001-08-27 Akim Demaille <akim@epita.fr>
11288 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11289 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11290 readable.
11291 Adjust callers.
11292 * doc/autoconf.texi (Configuration Actions): Document the vars
11293 available in commands.
11294 Emphasize the risks of collisions in init-cmds.
11296 2001-08-27 Akim Demaille <akim@epita.fr>
11298 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
11299 (Initializing configure): this new node.
11301 2001-08-27 Akim Demaille <akim@epita.fr>

11324 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
11325 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
11326 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
11327 -> ac_dir).
11328 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
11329 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
11331 2001-08-27 Akim Demaille <akim@epita.fr>

11357 (AMTAR): Help automake define it.
11358 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
11359 needed, 1.5 can have a macro and a target with the same name.
11360 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
11361 * m4/strip.m4: New.

11374 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
11375 Adjust callers.
11376 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11377 the name of the directory they're in, instead of the filename,
11378 since version.m4 is now in m4sugar, but m4_acversion must not be
11379 classified as an Autoconf macro.
11380 ($input_m4): Don't qualify the path to m4sugar.
11381 Rather, pass autoconf_dir to m4.
11382 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
11383 * tests/suite.at: Require 2.52c.
11385 2001-08-27 Akim Demaille <akim@epita.fr>

11397 of config.log on traps.
11398 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
11399 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
11400 for config.status'.
11401 Open the log as soon as possible.
11402 Use the same log introduction as configure's.
11404 2001-08-22 Paul Eggert <eggert@twinsun.com>
11406 * doc/autoconf.texi (Indices): New node.
11407 Move indices out of the top level menu and into this submenu.
11409 2001-08-22 Akim Demaille <akim@epita.fr>
11411 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11412 AC_TRY_COMMAND.
11413 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.

11454 * configure.ac (AT_CONFIG): Fix the path.

11456 can be used.
11458 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
11460 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
11461 program with AC_LANG_PROGRAM before feeding it to
11462 AC_COMPILE_IFELSE. Cleanup grep usage.
11464 2001-08-20 Akim Demaille <akim@epita.fr>
11466 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
11467 * NEWS, README, README-alpha, TODO, tests/README: This package is
11468 `Autoconf', not `autoconf' (the executable).
11470 2001-08-20 Akim Demaille <akim@epita.fr>
11472 Info readers seem to need `Index' in the index node title :(
11474 * doc/autoconf.texi: Reverse the 2001-08-15 change which
11475 simplified index node names.
11477 2001-08-20 Akim Demaille <akim@epita.fr>
11479 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
11480 arguments are not literals.
11481 * doc/autoconf.texi (Input) <AC_INIT>: Arguments must be literals.
11482 Specify the output variables, and macros defined.
11484 2001-08-20 Akim Demaille <akim@epita.fr>
11486 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
11487 (Examining Syntax) <AC_TRY_COMPILE>
11488 (Examining Libraries) <AC_TRY_LINK>
11489 (Test Programs) <AC_TRY_RUN>: These macros double quote some of
11490 their arguments.
11491 Reported by Werner Lemberg.
11493 2001-08-20 Akim Demaille <akim@epita.fr>

11510 * lib/autoconf/general.m4 (_AC_OUTPUT_COMMANDS): Say what you do.

11512 test suite lives.
11513 Create `atconfig' automagically.

11519 2001-08-20 Akim Demaille <akim@epita.fr>
11521 Huh!?!?! There are still some user EOF tags used, which prevents
11522 their use in AC_CONFIG_COMMANDS for instance...
11524 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
11525 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
11526 `_CSEOF', or `_ATEOF', as appropriate.
11527 * lib/m4sugar/Makefile.am, lib/autoconf/Makefile.am,
11528 * lib/autotest/Makefile.am (check-local): Enforce this constraint.

11588 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

11604 2001-08-17 Akim Demaille <akim@epita.fr>
11606 * doc/autoconf.texi: Work around Texinfo buglets.
11607 (Transformation Rules): One example is enough, users are expected
11608 to have their brains on. And BTW, use DESTDIR.
11609 (dvar): New macro. Use it.
11611 2001-08-17 Akim Demaille <akim@epita.fr>

11653 value.

11661 (cvs-dist): depends upon it.
11663 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
11665 * tests/Makefile.am: Use a clean-local rule to remove
11666 autom4te.cache (it's a directory, not a file.
11667 * Makefile.am: Ditto (but maintainer-clean-local).
11669 2001-08-15 Akim Demaille <akim@epita.fr>
11671 * bin/autom4te.in (@m4_warning): New.
11672 (&handle_m4): Use it.
11673 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
11674 warnings are issued at each run.
11675 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
11676 is in the src tree.
11678 2001-08-15 Akim Demaille <akim@epita.fr>
11680 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
11681 don't waste time running `autoupdate --version' works.
11682 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
11684 2001-08-13 Akim Demaille <akim@epita.fr>
11686 * doc/autoconf.texi (ma): Rename this index as...

11743 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11745 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
11746 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
11747 * doc/autoconf.texi (C Compiler Characteristics): Update
11748 documentation for AC_C_BIGENDIAN.
11750 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11752 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11753 magic values from an object file when cross-compiling.
11754 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11756 2001-08-10 Akim Demaille <akim@epita.fr>
11758 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11759 effects.
11760 Suggested by Russ Allbery.
11762 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11764 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11765 current $prefix to the sub-configures.
11767 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11769 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
11770 extension (needed on BeOS). Reported by Guido van Rossum.
11772 2001-08-09 Akim Demaille <akim@epita.fr>
11774 * bin/autom4te.in ($icache): Load it only if older than autom4te.
11776 2001-08-07 Akim Demaille <akim@epita.fr>
11778 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11779 removed.
11780 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11781 No need to remove the files before and after the each test, before
11782 each test and at the end of the suite is enough.
11783 Display only the children `times', not the shell's.
11784 If the test failed or was skipped, at-times is not available.
11786 2001-08-07 Akim Demaille <akim@epita.fr>
11788 Always produce testsuite.log, including when there are no
11789 failures. This helps getting information on skipped tests, and
11790 duration of the tests. Err, implement the latter btw.
11792 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
11793 Dump information on the first run of each test.
11794 (AT_CLEANUP): Create `at-times' containing the duration of the
11795 test group.
11797 2001-08-07 Akim Demaille <akim@epita.fr>
11799 The use of `dumpstat' revealed that `len' was used although it
11800 should not. m4_text_wrap was using it, but in the Autoconf world
11801 where it is legal. Hence (i) test M4sh in its own world, not
11802 Autoconf's, and (ii), ahem, fix the bug :)
11804 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11805 does not like `' instead of [].
11806 (AT_INIT): Forbid `^_?AT_'.
11807 And don't output such tokens.
11808 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11809 `script.as', and `autom4te.cache'.
11810 Remove `empty' and `macro' which are no longer used.
11811 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11812 * tests/m4sugar.at: Use it.
11813 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11815 2001-08-07 Akim Demaille <akim@epita.fr>
11817 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
11819 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
11821 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
11823 2001-08-04 Akim Demaille <akim@epita.fr>
11825 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
11826 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
11827 AC_TRY_LINK.
11828 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
11829 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
11830 (AC_F77_MAIN): Likewise.
11832 2001-08-04 Akim Demaille <akim@epita.fr>
11834 Don't rely on M4sugar outputting the patterns in files, since we
11835 might process the output _without_ running m4, hence without these
11836 files.
11838 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
11839 * bin/autom4te.in (@Request::includes): Remove, unused.
11840 (@Request::source): Rename as...
11841 (@Request::input): this.
11842 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
11843 (&handle_output): Fetch the patterns from the traces.
11844 `$forbidden' and `$allowed' are constant: use m//o.
11845 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
11846 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
11848 2001-08-04 Akim Demaille <akim@epita.fr>
11850 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
11851 autoconf', i.e., in addition to caching traces, cache the output.
11853 * bin/autom4te.in (Request::cache): Rename as...
11854 (Request::id): this.
11855 ($cache, $icache, $tcache, $ocache): New.
11856 (&handle_m4): Save M4 output in the cache instead of $tmp.
11857 (&handle_output): Adjust.
11858 (&up_to_date_p): Check that the output cache is up to date too.
11859 (top level): Run `&handle_m4' iff force or the cache is invalid.
11860 Run `&handle_output' if the output cache is more recent.
11862 2001-08-04 Akim Demaille <akim@epita.fr>
11864 * bin/autom4te.in ($force): New.
11865 (&parse_args, &print_usage): -f, --force is a new option.
11866 (&handle_output): CPP directives might have spaces after `#'.
11867 (&parse_args): The first file only can be frozen.
11869 2001-08-04 Akim Demaille <akim@epita.fr>
11871 Don't let autom4te compute the `include' traces several times:
11872 first check that the trace cache file is up to date, and then
11873 compare its timestamp with that of the output.
11875 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
11876 the preamble. Don't require 5.005 as Autom4te::General does it,
11877 and better yet (use `use', not `require'!).
11878 * lib/Autom4te/Struct.pm: Rename the last occurrences of
11879 Class::Struct as Autom4te::Struct.
11880 * lib/Autom4te/General.pm (File::stat): Use it.
11881 (&mtime): New, export it.
11882 * bin/autom4te.in: Use it.
11883 Declare `$req' is invalid if it is outdated.
11884 Don't declare it valid before saving it if something went wrong.
11886 2001-08-04 Akim Demaille <akim@epita.fr>
11888 Autom4te shall not encode Autoconf data, and preselecting traces
11889 must be proposed to the users.
11891 * bin/autom4te.in (@required_trace): Remove.
11892 (@preselect): New.
11893 (&parse_args, &print_usage): -p, --preselect is a new option.
11894 (&up_to_date_p): Adjust.
11895 * bin/autoconf.in: Preselect some Autoconf macros.
11897 2001-08-04 Akim Demaille <akim@epita.fr>
11899 * tests/tools.at (autoconf --trace: user macros): Check traces on
11900 macros invoked without arguments, and macros invoked with multiple
11901 lines arguments.
11903 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
11905 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
11906 arguments.
11908 2001-08-03 Akim Demaille <akim@epita.fr>
11910 * bin/autoconf.in ($@): Work around the usual sh bug.
11911 From Nicolas Joly.
11913 2001-08-03 Akim Demaille <akim@epita.fr>
11915 Clean up the handling of the M4 builtins tracing exception.
11917 * bin/autom4te.in (Request::request): Don't complete M4 builtins
11918 trace requests.

11920 (@m4_builtin): this.
11921 (%m4_builtin_alternate_name): New.
11922 (&parse_args): Complete the trace requests with alternate names.
11923 (&handle_traces): Hence no longer do it here.
11924 (&trace_requests): Remove, unused.
11926 2001-08-03 Akim Demaille <akim@epita.fr>
11928 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
11929 m4_if, and m4_wrap.
11931 2001-08-03 Akim Demaille <akim@epita.fr>
11933 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
11934 (m4_divert_pop): Dump the whole diversion stack when a diversion
11935 mismatch happens.
11936 * bin/autom4te.in (&handle_output): Remember of the first
11937 occurrence of a possibly undefined macro, not the last.
11938 Complain about the possibly undefined macros in the same order as
11939 the appear in the output.
11940 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
11941 * tests/tools.at (autoconf: forbidden tokens, basic)
11942 (autoconf: forbidden tokens, exceptions): No longer sort
11943 autoconf's stderr, as it is now deterministic.
11944 Check that `dnl' is caught.
11946 2001-08-01 Akim Demaille <akim@epita.fr>
11948 * configure.ac: Bump to 2.52c.

11962 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
11963 `die'.
11964 (&END): New.
11965 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
11966 `END', as `Autom4te::General::END' will be triggered.
11967 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
11968 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

12360 compiler, not the preprocessor.
12361 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use

12367 2001-07-03 Akim Demaille <akim@epita.fr>

12397 dummy alternate main is required even if the user provides her own
12398 'main'.

12400 provide an alternate 'main' function name, using the 'main' from
12401 the Fortran libraries.
12402 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
12403 cross-language link tests can be performed successfully.
12404 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
12405 after $LIBS, for consistency; this should be the general rule since
12406 the user may want to link to Fortran libraries that require $FLIBS.
12407 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.
12409 2001-06-29 Pavel Roskin <proski@gnu.org>
12411 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
12412 at-stdout and at-stderr instead of removing the newline
12413 from the echo output, which is not guaranteed to work.
12415 2001-06-28 Jens Petersen <petersen@redhat.com>
12417 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to

12451 (&output_kind): here.
12452 (File::Basename): Use it.

12461 Suggested by Mo DeJong.
12463 2001-06-24 Akim Demaille <akim@epita.fr>

12474 2001-06-23 Akim Demaille <akim@epita.fr>
12476 * tests/torture.at (AC_ARG_VAR): Make it a single test instead of
12477 three as failures are unlikely, and speed matters.
12479 2001-06-23 Akim Demaille <akim@epita.fr>
12481 * doc/autoconf.texi (Redefined M4 Macros): New.
12483 2001-06-23 Akim Demaille <akim@epita.fr>
12485 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider
12486 inttypes.h is missing if it conflicts with sys/types.h, as on IRIX
12487 5.3.
