5 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
6 or any of the other *dir variables contain a space.
8 Please note that Automake does not and cannot support spaces in
9 filenames that are involved during the build. This change affects
10 only installation paths, so that `make install' does not bomb out
11 in packages configured with
12 ./configure --prefix '/c/Program Files'
14 - Fix the depfiles output so it works with GNU sed (<4.1) even when
15 POSIXLY_CORRECT is set.
17 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
18 since Autoconf 2.54, which defines LIBOBJS itself.
20 - Fix a potential (but unlikely) race condition in parallel elisp
21 builds. (Introduced in 1.7.3.)
23 - Do not assume that users override _DEPENDENCIES in all conditions
24 where Automake will try to define them.
26 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
27 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
30 This fix also affects the $(mkdir_p) variable defined since
31 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
32 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
34 - Secure temporary directory creation in `make distcheck'. (PR/413)
36 - Do not generate two build rules for `parser.h' when the
37 parser appears in two different conditionals.
39 - Work around a Solaris 8 /bin/sh bug in the test for dependency
40 checking. Usually ./configure will not pick this shell; so this
41 fix only helps cases where the shell is forced to /bin/sh.
43 * Bugs introduced by 1.8:
45 - In some situations (hand-written `m4_include's), aclocal would
46 call the `File::Spec->rel2abs' method, which was only introduced
47 in Perl 5.6. This new version reestablish support Perl 5.005.
49 It is likely that the next major Automake releases will require at
50 least Perl 5.6. Consider upgrading your development environment
51 if you are still using the five-year-old Perl 5.005.
53 - Automake would sometimes fail to define rules for targets listed
54 in variables defined in multiple conditions. For instance on
60 it would define only the `a.$(OBJEXT): a.c' rule and omit the
61 `b.$(OBJEXT): b.c' rule.
63 * New sections in manual:
65 - Third-Party Makefiles: how to interface third party Makefiles.
66 - Upgrading: upgrading packages to newer Automake versions.
67 - Multiple Outputs: handling tools that produce many outputs.
71 * A (well known) portability bug slipped in the changes made to
72 install-sh in Automake 1.8.1. The broken install-sh would refuse to
73 install anything on Tru64.
75 * Fix install rules for conditionally built python files. (This never
80 * Bugs introduced by 1.8:
82 - Fix Config.pm import error with old Perl versions (at least
83 5.005_03). One symptom is that aclocal could not find its macro
86 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
87 created by `make install' are always world readable, even if the
88 installer happens to have an overly restrictive umask (e.g. 077).
89 This was a mistake and has been reverted. There are at least two
90 reasons why we must not use `-m 0755':
91 - it causes special bits like SGID to be ignored,
92 - it may be too restrictive (some setups expect 775 directories).
94 - Fix aclocal to honor definitions located in files which have been
95 m4_included manually. aclocal 1.8 had been updated to check
96 m4_included files for new requirements, but forgot that these
97 m4_included files can also provide new definitions.
99 Note that if you have such a setup, we recommend you get rid of
100 it. In the past, there was a reason to m4_include files manually:
101 aclocal used to duplicate entire M4 files into aclocal.m4, even
102 files that were distributed. Some packages were therefore
103 m4_including the distributed file directly, and playing some
104 tricks to ensure aclocal would not copy that file to aclocal.m4,
105 in order to limit the amount of duplication. Since aclocal 1.8.x
106 will precisely output m4_includes for local M4 files, we recommend
107 that you clean up your setup, removing all manual m4_includes and
108 letting aclocal output them.
110 - Output detailed menus in the Info version if the Automake manual,
111 so that Emacs can locate the indexes.
113 - configure.ac and configure were listed twice in DIST_COMMON (an
114 internal variable where Automake lists configury files to
115 distribute). This was harmless, but unaesthetic.
117 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
118 This was an issue only in the Automake package itself, not in
121 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
122 DEST:SRC. This was wrong, as some packages do
123 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
126 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
127 argument. This caused two kinds of failures:
128 - Rules installing data in a conditionally defined directory
129 failed when that directory was undefined. In this case no
130 argument was supplied.
131 - `make installdirs' failed, because several directories were
132 passed to $(mkdir_p). This was an issue only on platform
133 were $(mkdir_p) is implemented with `install-sh -d'.
134 $(mkdir_p) as been changed to accept 0 or more arguments, as
137 * Long-standing bugs:
139 - Fix an unexpected diagnostic occurring when users attempt
140 to override some internal variables that Automake appends to.
142 - aclocal now scans configure.ac for macro definitions (PR/319).
144 - Fix a portability issue with OSF1/Tru64 Make. If a directory
145 distributes files which are outside itself (this usually occurs
146 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
147 from a parent package), then `make distcheck' fails due to an
148 optimization performed by OSF1/Tru64 Make in its VPATH handling.
149 (tests/subpkg2.test failure)
151 - Fix another portability issue with Sun and OSF1/Tru64 Make.
152 In a VPATH-build configuration, `make install' would install
153 nobase_ files to wrong locations.
155 - Fix a Perl `uninitialized value' diagnostic occurring when
156 automake complains that a Texinfo file does not have a
157 @setfilename statement.
159 - Erase config.status.lineno during `make distclean'. This file
160 can be created by config.status. Automake already knew about
161 configure.lineno, but forgot config.status.lineno.
163 - Distribute all files, even those which are built and installed
164 conditionally. This change affects files listed in conditionally
165 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
166 as well as those listed in conditionally defined dist_*_DATA,
167 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
169 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
170 doesn't conform to POSIX.
172 - Normalize help strings for configure variables and options added
177 - Check for python2.4 in AM_PATH_PYTHON.
179 * Spurious failures in test suite:
181 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
182 tests/ltconv.test: fix failures with CVS Libtool.
183 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
184 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
185 fix failures with old Texinfo versions.
191 - The NEWS file is more verbose.
195 - Autoconf 2.58 or greater is required.
199 - Default source file names in the absence of a _SOURCES declaration
200 are made by removing any target extension before appending `.c', so
201 to make the libtool module `foo.la' from `foo.c', you only need to
204 lib_LTLIBRARIES = foo.la
205 foo_la_LDFLAGS = -module
207 For backward compatibility, foo_la.c will be used instead of
208 foo.c if this file exists or is the explicit target of a rule.
209 However -Wobsolete will warn about this deprecated naming.
211 - AR's `cru' flags are now set in a global ARFLAGS variable instead
212 of being hard-coded in each $(AR) invocation, so they can be
213 substituted from configure.ac. This has been requested by people
214 dealing with non-POSIX ar implementations.
216 - New warning option: -Woverride. This will warn about any user
217 target or variable definitions which override Automake
220 - Texinfo rules back up and restore info files when makeinfo fails.
222 - Texinfo rules now support the `html' target.
223 Running this requires Texinfo 4.0 or greater.
225 `html' is a new recursive target, so if your package mixes
226 hand-crafted `Makefile.in's with Automake-generated
227 `Makefile.in's, you should adjust the former to support (or
228 ignore) this target so that `make html' recurses successfully. If
229 you had a custom `html' rule in your `Makefile.am', it's better to
230 rename it as `html-local', otherwise your rule will override
231 Automake's new rule (you can check that by running `automake
232 -Woverride') and that will stop the recursion to subdirectories.
234 Last but not least, this `html' rule is declared PHONY, even when
235 overridden. Fortunately, it appears that few packages use a
236 non-PHONY `html' rule.
238 - Any file which is m4_included from configure.ac will appear as a
239 configure and Makefile.in dependency, and will be automatically
242 - The rules for rebuilding Makefiles and Makefile.ins will now
243 rebuild all Makefiles and all Makefile.ins at once when one of
244 configure's dependencies has changed. This is considerably faster
245 than previous implementations, where config.status and automake
246 were run separately in each directory (this still happens when you
247 change a Makefile.am locally, without touching configure.ac or
248 friends). Doing this also solves a longstanding issue: these
249 rebuild rules failed to work when adding new directories to the
250 tree, forcing you to run automake manually.
252 - For similar reasons, the rules to rebuild configure,
253 config.status, and aclocal.m4 are now defined in all directories.
254 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
255 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
256 should better define them in all directories. This is easily done
257 using an AC_SUBST (make sure you prefix these dependencies with
258 $(top_srcdir) since this variable will appear at different
259 levels of the build tree).
261 - aclocal will now use `m4_include' instead of copying local m4
262 files into aclocal.m4. (Local m4 files are those you ship with
263 your project, other files will be copied as usual.)
265 Because m4_included files are automatically distributed, it means
266 for most projects there is no point in EXTRA_DISTing the list of
267 m4 files which are used. (You can probably get rid of
268 m4/Makefile.am if you had one.)
270 - aclocal will avoid touching aclocal.m4 when possible, so that
271 Autom4te's cache isn't needlessly invalidated. This behavior can
272 be switched off with the new `--force' option.
274 - aclocal now uses Autoconf's --trace to detect macros which are
275 actually used and will no longer include unused macros simply
276 because they where mentioned. This was often the case for macros
277 called conditionally.
279 - New options no-dist and no-dist-gzip.
281 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
282 py-compile, and ylwrap, now all understand --version and --help.
284 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
285 links as part of the distclean target and including source files in
288 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
289 argument. The latter can be used to override the default behavior
292 - Automake will exit with $? = 63 on version mismatch. (So does
293 Autoconf 2.58) missing knows this, and in this case it will
294 emulate the tools as if they were absent. Because older versions
295 of Automake and Autoconf did not use this exit code, this change
296 will only be useful in projects generated with future versions of
299 - When using AC_CONFIG_FILES with multiple input files, Automake
300 generates the first ".in" input file for which a ".am" exists.
301 (Former versions would try to use only the first input file.)
303 - lisp_DATA is now allowed. If you are using the empty ELCFILES
304 idiom to disable byte-compilation of lisp_LISP files, it is
305 recommended that you switch to using lisp_DATA. Note that
306 this is not strictly equivalent: lisp_DATA will install elisp
307 files even if emacs is not installed, while *_LISP do not
308 install anything unless emacs is found.
310 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
311 available. This selection is achieved through the Makefile
312 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
313 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
314 `$(install_sh) -m 0755 -d'.
318 - Because `mkdir -p' is available on most platforms, and we can use
319 `install-sh -d' when it is not, the use of the mkinstalldirs
320 script is being phased out. `automake --add-missing' no longer
321 installs it, and if you remove mkinstalldirs from your package,
322 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
324 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
325 gettextize and autopoint will install it when needed. Automake
326 will continue to define the $(mkinstalldirs) and to distribute
327 mkinstalldirs when this script is in the source tree.
329 - AM_PROG_CC_STDC is now empty. The content of this macro was
330 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
331 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
332 renaming should be safe, even if you have to support several,
333 versions of Automake, because AC_PROG_CC defines this variable
334 since Autoconf 2.54.)
336 - Some users where using the undocumented ACLOCAL_M4_SOURCES
337 variable to override the aclocal.m4 dependencies computed
338 (inaccurately) by older versions of Automake. Because Automake
339 now tracks configure's m4 dependencies accurately (see m4_include
340 above), the use of ACLOCAL_M4_SOURCES should be considered
341 obsolete and will be flagged as such when running `automake
346 - Defining programs conditionally using Automake conditionals no
347 longer leads to a combinatorial explosion. The following
348 construct used to be troublesome when used with dozens of
363 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
365 - Due to implementation constraints, previous versions of Automake
366 proscribed multiple conditional definitions of some variables
376 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
377 This restriction has been lifted, and these variables now
378 support multiple conditional definitions as do other variables.
380 - Cleanup the definitions of $(distdir) and $(top_distdir).
381 $(top_distdir) now points to the root of the distribution
382 directory created during `make dist', as it did in Automake 1.4,
383 not to the root of the build tree as it did in intervening
384 versions. Furthermore these two variables are now only defined in
385 the top level Makefile, and passed to sub-directories when running
388 - The --no-force option now correctly checks the Makefile.in's
389 dependencies before deciding not to update it.
391 - Do not assume that make files are called Makefile in cleaning rules.
393 - Update .info files in the source tree, not in the build tree. This
394 is what the GNU Coding Standard recommend. Only Automake 1.7.x
395 used to update these files in the build tree (previous versions did
396 it in the source tree too), and it caused several problems, varying
397 from mere annoyance to portability issues.
399 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
400 when --add-missing and --force-missing are used. For backward
401 compatibility --add-missing will continue to install COPYING (in
402 `gnu' strictness) when none of these three files exist, but this
403 use is deprecated: you should better choose a license yourself and
404 install it once for all in your source tree (and in your code
407 - Fix ylwrap so that it does not overwrite header files that haven't
408 changed, as the inline rule already does.
410 - User-defined rules override automake-defined rules for the same
411 targets, even when rules do not have commands. This is not new
412 (and was documented), however some of the automake-generated
413 rules have escaped this principle in former Automake versions.
414 Rules for the following targets are affected by this fix:
416 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
417 info, info-am, install-data-am, install-exec-am, install-info,
418 install-info-am, install-man, installcheck-am, maintainer-clean,
419 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
420 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
422 Practically it means that an attempt to supplement the dependencies
423 of some target, as in
427 will now *silently override* the automake definition of the
428 rule for this target. Running `automake -Woverride' will diagnose
429 all such overriding definitions.
431 It should be noted that almost all these targets support a *-local
432 variant that is meant to supplement the automake-defined rule
433 (See node `Extending' in the manual). The above rule should
436 clean-local: my-clean-rule
438 These *-local targets have been documented since at least
439 Automake 1.2, so you should not fear the change if you have
440 to support multiple automake versions.
444 - The Automake manual is now distributed under the terms of the GNU FDL.
446 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
448 - core dumps are no longer removed by the cleaning rules. There are
449 at least three reasons for this:
450 1. These files should not be created by any build step,
451 so their removal do not fit any of the cleaning rules.
452 Actually, they may be precious to the developer.
453 2. If such file is created during a build, then it's clearly a
454 bug Automake should not hide. Not removing the file will
455 cause `make distcheck' to complain about its presence.
456 3. Operating systems have different naming conventions for
457 core dump files. A core file on one system might be a
458 completely legitimate data file on another system.
460 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
461 defined by Automake. This means that any definition in the
462 environment will be used, unless overridden in the Makefile.am or
463 on the command line. The old behavior, where these variables were
464 defined empty in each Makefile, can be obtained by AC_SUBSTing or
465 AC_ARG_VARing each variable from configure.ac.
467 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
468 documented. (The is not a new feature, these variables have
469 been there since at least Automake 1.4.)
472 * Fix install-strip to work with nobase_ binaries.
473 * Fix renaming of #line directives in ylwrap.
474 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
477 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
478 * Fix detection of Debian's install-info, broken since version 1.5.
479 (Debian bug #213524).
480 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
481 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
484 * The implementation of automake's --no-force option is unreliable,
485 so this option is ignored in this version. A real fix will appear in
486 Automake 1.8. (Debian Bug #206299)
487 * AM_PATH_PYTHON: really check the whole list of interpreters if no
488 argument is given. (PR/399)
489 * Do not warn about leading `_' in variable names, even with -Wportability.
490 * Support user redefinitions of TEXINFO_TEX.
491 * depcomp: support AIX Compiler version 6.
492 * Fix missing rebuilds during `make dist' with BSD make.
493 (Could produce tarballs containing out-of-date files.)
494 * Resurrect multilib support.
495 * Noteworthy manual updates:
496 - Extending aclocal: how to write m4 macros that won't trigger warnings
498 - A Shared Library: Rewrite and split into subsections.
501 * Fix depcomp's icc mode for ICC 7.1.
502 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
503 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
504 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
505 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
506 * Remove Latin-1 characters from elisp-comp.
507 * Update the manual's @dircategory to match the Free Software Directory.
510 * Update install-sh's license to remove an advertising clause.
512 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
513 that caused invalid Makefile.ins to be generated.
514 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
515 * New FAQ entry: renamed objects.
518 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
519 the Emacs implementation)
520 * Fix output of aclocal.m4 dependencies in subdirectories.
521 * Use `mv -f' instead of `mv' in fastdep rules.
522 * Upgrade mdate-sh to work on OS/2.
523 * Don't byte-compile elisp files when ELCFILES is set empty.
524 (this documented feature was broken by 1.7.3)
525 * Diagnose trailing backslashes on last line of Makefile.am.
526 * Diagnose whitespace following trailing backslashes.
527 * Multiple tests are now correctly supported in DEJATOOL. (PR/388)
528 * Fix rebuilt rules for AC_CONFIG_FILES([Makefile:Makefile.in:Makefile.bot])
530 * `make install' will build `BUILT_SOURCES' first.
531 * Minor documentation fixes.
534 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
535 * Query distutils for `pythondir' and `pythonexecdir', instead of
536 using an hardcoded path. This should allow builds on 64-bit
537 distributions that usually use lib64/ instead of lib/.
538 * AM_PATH_PYTHON will also search for python2.3.
539 * elisp files are now built all at once instead of one by one. Besides
540 incurring a speed-up, this is required to support interdependent elisp files.
542 - `make distcheck' will now work in `_inst/' and `_build' instead
543 of `=inst/' and `=build/'
544 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
545 - install/uninstall `*.i[0-9][0-9]'-style info files
546 - more changes that affect only the Automake package (not its output)
547 * Fix some incompatibilities with upcoming perl-5.10.
548 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
551 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
552 is troublesome with gcc and Solaris compilers. (PR/385)
553 - makedepend mode: work with Libtool. (PR/385 too)
555 * better support for unusual gettext setups, such as multiple po/ directories
557 - Flag missing po/ and intl/ directories as warnings, not errors.
558 - Disable these warnings if po/ does not exist.
559 * Noteworthy manual updates:
561 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
563 - Document `AM_YFLAGS = -d'. (PR/382)
566 * Fix installation and uninstallation of Info files built in subdirectories.
567 * Do not run `./configure --with-included-gettext' during `make distcheck'
568 if AM_GNU_GETTEXT([external]) is used.
569 * Correctly uninstall renamed man pages.
570 * Do not strip escaped newline in variables defined in one condition
571 and augmented in another condition.
572 * Fix ansi2knr rules for LIBOBJS sources.
573 * Clean all known Texinfo index files, not only those which appear to
574 be used, because we cannot know wich indexes are used in included files.
575 (PR/375, Debian Bug #168671)
576 * Honor only the first @setfilename seen in a Texinfo file.
577 * Treat "required file X not found" diagnostics as errors (exit status 1).
578 * Don't complain that a required file is not found when it is a Makefile
580 * Don't use single suffix inference rules when building `.info'-less
581 Info files, for the sake of Solaris make.
582 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
583 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
584 * Warn about multiple inference rules when -Wportability is used. (PR/372)
585 * Fix building of deansified files from subdirectories. (PR/370)
586 * Add missing `fi' in the .c->.obj rules.
587 * Improve install-sh to work even when names contain spaces or certain
588 (but not all) shell metachars.
589 * Fix the following spurious failures in the test suite:
590 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
591 * Noteworthy manual updates:
592 - Augment the section about BUILT_SOURCES.
593 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
596 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
598 * Aclocal should now recognize macro names containing parentheses, e.g.
599 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
600 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
602 * Install Python files even if they were built. (PR/369)
603 * Have stamp-vti dependent upon configure instead of configure.ac, as the
604 version might not be defined in the latter. (PR/358)
605 * Reorder arguments passed to a couple of commands, so things works
606 when POSIXLY_CORRECT=1.
607 * Fix a regex that can cause Perl to segfault on large input.

622 * Autoconf 2.54 is required.
623 * `aclocal' and `automake' will no longer warn about obsolete

625 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
626 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
627 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
628 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
629 `configure.ac' for you.
630 * Support for per-program and per-library `_CPPFLAGS'.
631 * New `ctags' target (builds CTAGS files).
632 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
633 (see `automake --help' or the manual for a list of them).
634 * Honor the WARNINGS environment variable.
635 * Omit the call to depcomp when using gcc3: call the compiler directly.

640 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
642 * `make distcheck' will enforce DESTDIR support by attempting
644 * `+=' can be used in conditionals, even if the augmented variable
645 was defined for another condition.
646 * Makefile fragments (inserted with `include') are always distributed.
647 * Use Autoconf's --trace interface to inspect configure.ac and get
648 a more accurate view of it.
649 * Add support for extending aclocal's default macro search path
650 using a `dirlist' file within the aclocal directory.
651 * automake --output-dir is deprecated.
652 * The part of the distcheck target that checks whether uninstall actually
653 removes all installed files has been moved in a separate target,
654 distuninstallcheck, so it can be overridden easily.
658 * Support for AM_INIT_GETTEXT([external])
659 * Bug fixes, including:
660 - Fix Automake's own `make install' so it works even if `ln' doesn't.
661 - nobase_ programs and scripts honor --program-transform correctly.
662 - Erase configure.lineno during `make distclean'.
663 - Erase YACC and LEX outputs during `make maintainer-clean'.
666 * Many bug fixes, including:
667 - Requiring the current version works.

678 - Don't choke on AM_LDFLAGS definitions.
679 - Clean libtool objects from subdirectories.
680 - Allow configure variables with reserved suffix and unknown prefix
681 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
682 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
685 * Autoconf 2.52 is required.
686 * automake no longer run libtoolize.
687 This is the job of autoreconf (from GNU Autoconf).
688 * `dist' generates all the archive flavors, as did `dist-all'.
689 * `dist-gzip' generates the Gzip tar file only.
690 * Combining Automake Makefile conditionals no longer lead to a combinatorial
691 explosion. Makefile.in's keep a reasonable size.
692 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
693 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
695 * `#line' of Lex and Yacc files are properly set.
696 * EXTRA_DIST can contain generated directories.
697 * Support for dot-less extensions in suffix rules.
698 * The part of the distcheck target that checks whether distclean actually

707 * Added uninstall-hook target
708 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
709 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
710 (Note that "pkgname" is not "tarname", see the manual for details.)
711 It is also possible to pass a list of global Automake options as
712 first argument to this new form of AM_INIT_AUTOMAKE.
713 * Compiler-based assembler is now called `CCAS'; people expected `AS'
714 to be a real assembler.
715 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
716 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
717 * aclocal and automake are also installed with the version number
718 appended, and some of the install directory names have changed.
719 This lets you have multiple versions installed simultaneously.
