ithreads: use runtime (not configure time) detection of perl threads
I can't imagine the runtime checks being a big runtime penalty, so there
shouldn't be a need to do the checks at configure check and hardcode the
result in the generated automake.
With the current system, it means if you change your perl config (build
perl w/threads, build automake, build perl w/out threads), or deploy a
compiled automake package on a different system (build had threads, but
deployed system does not), you get errors when trying to run automake.
So take the logic from configure.ac and move it to the one place where
PERL_THREADS is used (lib/Automake/Config.in) and do the version/config
checking at runtime.
* bootstrap.sh (PERL_THREADS): Delete assignment and use in sed.
* configure.ac (am_cv_prog_PERL_ithreads, PERL_THREADS): Delete all code
related to these two variables.
* lib/Automake/Config.in (perl_threads): Initialize to 0, and only set to
1 if the perl version is at least 5.007_002, and useithreads is in Config.

compile: use 'compile' script when "-c -o" is used with losing compilers
Do so seen when only source files in the "current" directory are present.
This commit is part of a series of related changes addressing automake
bug#13378 (see also the plan 'PLANS/subdir-objects.txt').
Before this change, Automake-generated C compilation rules mistakenly
passed the "-c -o" options combination unconditionally (even to losing
compiler) when the 'subdir-objects' was used but sources were only
present in the top-level directory. Issue spotted by Nick Bowler:
We fix this by having Automake redefine AC_PROG_CC to take over the role
of AM_PROG_CC_C_O and to require the 'compile' script unconditionally
(albeit that will continue to be invoked only when inferior compilers
are detected).
Among other things, this means AM_PROG_CC_C_O explicitly is no longer
required; that macro is still supported for backward-compatibility, but
calling it is basically a no-op now.
This change has some pros and some cons (obviously, we believe the former
outweighs the latter). Here are the most relevant ones:
+ Pros 1:
Some logic in the Automake script has been simplified.
+ Pros 2:
That simplification has automatically fixed an actual bug (see
Nick's mails referenced above; admittedly, that was present only in
corner-case situations, but still); the test 't/ccnoco4.sh', which
demonstrated the bug and has been failing so far, now passes.
+ Pros 3:
Things works more "automagically" now (no need to manually add the
AM_PROG_CC_C_O macro to configure.ac anymore).
* Cons 1:
The 'compile' script will be required in all projects using C
compilation; this will only be a problem for packages not using
'--add-missing'. However, such packages are definitely more rare
than the ones using '--add-missing', and adjusting them will be
trivial -- just copy the compile script over from the new Automake
installation.
* Cons 2:
The copy & paste of autoconf internals hack this change has introduced
in our "rewrite" of AC_PROG_CC is really an egregious abomination. It
can only be justified with the fact that we expect future versions of
autoconf to implement the semantics we need directly in AC_PROG_CC, so
that we'll be able to leverage that (since Automake 1.14 will require
the latest Autoconf version released).
Now, the detailed list of file-by-file changes ...
* automake.in ($seen_cc_c_o): Remove this global variable.
(scan_autoconf_traces): Don't set it, and do not trace the
'AM_PROG_CC_C_O' m4 macro.
(lang_c_rewrite): Remove, no longer needed.
* doc/automake.texi: Adjust expected "autoreconf --install" output
in the amhello example. Remove statements about the need for the
AM_PROG_CC_C_O macro. Report it is obsolete now.
* m4/init.m4: Re-write AC_PROG_CC to append checks about whether the
C compiler supports "-c -o" together. These checks have basically
been ripped out (with adaptations) from the 'AC_PROG_CC_C_O' macro
of Autoconf and ...
* m4/minuso.m4 (AM_PROG_CC_C_O): ... this macro of ours, which has
thus basically become a no-op.
* t/ax/am-test-lib.sh (am_setup_testdir): Also copy the 'compile'
script in the test directory; if we don't do so, every test using
AC_PROG_CC should call automake with the "--add-missing" option, or
copy the 'compile' script itself.
* t/cond11.sh: No need to create a dummy 'compile' script: that is
already brought in by 'am_setup_testdir()', that is automatically
invoked when 'test-lib.sh' is sourced.
* t/add-missing.tap: Adjust: we expect the 'compile' script to be
required by a mere AC_PROG_CC call now.
* t/dist-auxdir-many-subdirs.sh: Likewise.
* t/specflg6.sh: Likewise.
* t/subobj4.sh: Likewise.
* t/cxx-lt-demo.sh: Likewise, and update comments to match.
* t/distcom2.sh: Enhance a little.
* t/dollarvar2.sh: Adjust.
* t/extra-portability.sh: Likewise.
* t/libobj19.sh: Likewise.
* t/per-target-flags.sh: Likewise.
* t/repeated-options.sh: Likewise.
* t/subobj.sh: Likewise, and enhance a little.
* t/ccnoco2.sh: Remove as obsolete.
* t/list-of-tests.mk (handwritten_TESTS): Adjust.
(XFAIL_TESTS): Remove 't/ccnoco4.sh'.
* NEWS: Update.
tests: can fake a compiler not grasping "-c -o" -- globally in all tests
The ability to easily do so will be quite important in upcoming changes
about C compilation handling and semantics of the 'subdir-objects'
option. Refer to the extensive discussion about automake bug#13378 for
more details: <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13378>.
See also commit 'v1.13.1-34-g744cd57' of 2013-01-08, "coverage: compile
rules used "-c -o" also with losing compilers".
* t/ax/cc-no-c-o.in: New, a "C compiler" that chokes when the '-c' and
'-o' options are passed together to it on the command line.
* Makefile.am (t/ax/cc-no-c-o): Generate this script from it.
(noinst_SCRIPTS, CLEANFILES): Add it.
(EXTRA_DIST): Add 't/ax/cc-no-c-o.in'.
(check-cc-no-c-o): New target, runs the whole testsuite with 'cc-no-c-o'
as the C compiler (bot GNU and non-GNU).
* .gitignore: Update.
* t/ccnoco.sh: Use the new script instead of duplicating it.
* t/ccnoco3.sh: Likewise.
* t/ccnoco4.sh: Likewise.
* t/self-check-cc-no-c-o.sh: New testsuite self-check.
* t/list-of-tests.mk: Adjust.
Otherwise, Git gets confused by the fact that a directory ('maint')
is named like a branch, and forces me to tweak the command line to
resolve the ambiguity for it.
depend2.am: fix comments on verbosity of compilation rules
The situation and decisions described on those comments have become
quite outdated since the introduction of the silent-rules support.
Today, the general idea is to have nice, terse output if silent rules
are enabled, and complete, faithful, very verbose output if they are
not -- without trying to "massage" this verbose output in a more
pleasant form if that would cause complication in the affected code.
So it's better to just drop the obsolescent comments.
Note that we don't start simplifying the existing rules according
to this new philosophy; that will only be done when touching some
existing code (for the 'depend2.am' code, that will probably happen
on the master branch).
* lib/am/depend2.am: The "fastdep" mode is supported not only for
gcc 3.x, but for gcc 3.x or later, in particular, for all gcc in
the 4.x series (at the time of writing, the latest release is 4.72).
Adjust the comments to match, and re-wrap them while at it.
* t/remake-renamed-m4-macro-and-file.sh: Adjust to reflect to old
"acloca22 -> t/aclocal-deleted-header.sh" test rename.
* t/aclocal-pr450.sh (configure.ac): Use '$me' in the AC_INIT call,
instead of hard-coding the old name of this test, i.e., "acloca19".
tests: fix an old botched change to an aclocal test
* t/acloca10.sh (configure.ac): Here, invoke the m4 macro 'MACRO2'
before the macro 'MACRO1' (the related test 't/aclocal-I-order-2.sh'
does the opposite). This reverts a botched edit done (by myself,
oops) in commit 'v1.11-1335-gefdc3e1' of 2011-09-11, "tests: minor
optimizations/simplifications in some aclocal tests", and makes the
behaviour of the test match once again what is stated in the
heading comments. While at it, improve those same heading comments
a little.
coverage: compile rules used "-c -o" also with losing compilers
If the 'subdir-objects' option is used, Automake-generated rules for
C compilation pass both the "-c" and "-o" options to the C compiler,
*unconditionally*. There are some compilers that choke on such an
usage, but the AM_PROG_CC_C_O macro takes care of them (it does so by
redefining $CC to use the Automake-provided 'compile' wrapper script
automatically, if a losing compiler is detected at configure runtime).
Unfortunately, in case the 'subdir-objects' option is specified in a
Makefile.am, but all the source files resided anyway in the top-level
directory (relative to the Makefile.am), Automake do *not* complain
if AM_PROG_CC_C_O wasn't invoked in 'configure.ac' -- all the while
still passing "-c -o" to the compiler invocations. This could cause
compilation failures with losing compilers if the user forget to call
AM_PROG_CC_C_O in 'configure.ac' (and Automake would not warn him of
the issue).
Expose this bug in the testsuite.

coverage: user can avoid distributing '.info' pages
Can be done like this:
AUTOMAKE_OPTIONS = info-in-builddir
dist-info:
@:
Note that this usage is not yet documented: we might decide to go
for a fully-fledged 'no-dist-info' flag, or something like that, in
future automake version (this is not yet decided); in which case,
it's better not to have people start to rely on the hack above.
Still, there's no good reason to break it gratuitously, hence this
test coverage.
* t/txinfo-nodist-info.sh: New test.
* t/list-of-tests.mk: Add it.
build: enable all warnings as fatal in our own build system
Automake should of course be able to bootstrap itself in a
warning-free manner w.r.t. the Autotools. So make any failure
to do so fatal. Not doing so caused the regression fixed by
previous commit 'v1.13.1-22-ga790fae' to go unnoticed.
* configure.ac (AM_INIT_AUTOMAKE): Add '-Werror' and '-Wall'.
* bootstrap.sh: Pass the '-Wall -Werror' options to aclocal,
automake and autoconf invocations.
texi: Texinfo sources and CLEANFILES definition should co-exist peacefully
But they don't now, due to a regression introduced in commit
'v1.13.1-4-gc1a8f56'. Fix it. The regression was hitting our
own build system!
* automake.in (handle_texinfo_helper): Only complain if the
'info-in-builddir' is not active and a '.info' file (not any
random file!) is listed in CLEANFILES or DISTCLEANFILES.
* t/ax/runtest.in: Accept options '-k' and '--keep-testdirs' (same
as exporting '$keep_testdirs' to "yes"). To improve compatibility
with the "make check" interface, allow environment variables to be
passes on the command line. Minor adjustments while at it.
Individual files or sub-directories about future and on-going
development plans in Automake will be added in follow-up commits.
This new set of documents is meant to help ensure a more controlled
and smooth development and evolution for Automake, in several ways.
- Having the plans clearly spelled out should will avoid messy
roadmaps with no clear way forward or with muddy or ill-defined
aims or purposes; a trap this is too easy to fall into.
- Keeping planned changes cooking and re-hashed for a while should
ensure rough edges are smoothed up, transitions are planned in a
proper way (hopefully avoiding debacles like the AM_MKDIR_PROG_P
deprecation and the AM_CONFIG_HEADER too-abrupt removal), and
"power users" have more chances of getting informed in due time,
thus having all the time to prepare for the changes or raise
objections against them.
- Having the plans clearly stated and registered in a "centralized"
location should make it more difficult to them to slip through
the cracks, getting forgotten or (worse) only half-implemented.
- Even for discussions and plans registered on the Bug Tracker
as well, a corresponding entry in the PLANS directory can help
in keeping main ideas summarized, and consensus and/or objections
registered and easily compared.
Motivation:
<http://blog.flameeyes.eu/2013/01/autotools-mythbuster-automake-pains>
Not a flatting picture for us (and maybe a little too harsh), but
basically true and even spot-on in some regards.
They are likely not general enough for widespread use, but they
are useful nonetheless.
In the best-case scenario, they will start to be used by other
people, and thus accordingly improved and made more general and
flexible.
In the worst case scenario, well, I still get to keep them in a
centralized, blessed place, simplifying the deployment and use
of them; so still a win for me :-)
tests: tweak tests on obsolete EXTRA_DATA variable
* t/extra3.sh, t/extra4.sh: Merge ....
* t/extra-data.sh: ... into this, with updated comments.
* t/list-of-tests.mk: Adjust. Also Tweak the order in
which some other tests are listed.
docs: re-introduce mention of two-args AM_INIT_AUTOMAKE invocation
Albeit obsolescent and raising warnings in the 'obsolete' category,
that usage is still supported, and will need to be until Autoconf
improves its handling of configure-time-generated package version
numbers. So it's better to explicitly document it again, stating
that it is obsoleted but still working (and why), rather then leaving
it as Yet Another Undocumented Feature (that will mysteriously and
suddenly break some random day in the future).
It's worth giving some background about how we ended up in the
situation that this patch fixes.
We had originally removed support for the long-deprecated two-args
AM_INIT_AUTOMAKE invocation (see commit v1.12-67-ge186355). Before
that removal could land in a released Automake version, Bob Friesenhahn
made a quite compelling point that the two-args AM_INIT_AUTOMAKE
invocation could still be useful for modern, maintained packages like
GraphicsMagick, at least until Autoconf is fixed to offer better support
for "dynamic" package versions (see commit v1.12.2-245-g2abe183 for more
in-depth rationales and references). However, in that commit we didn't
revert the removal of the *documentation* for this two-arguments
AM_INIT_AUTOMAKE invocation (and no rationale for not doing so was given
in the commit message). Time to remedy that.
Indirectly suggested by Diego Elio Pattenò:

texi: deprecate hack about info files in CLEANFILES variables
For quite a long time, Automake has been implementing an undocumented
hack which ensured that '.info' files which appeared to be cleaned (by
e.g. being listed in the CLEANFILES or DISTCLEANFILES variables) were
built in the builddir rather than in the srcdir; this hack was introduced
to ensure better backward-compatibility with packages such as Texinfo,
which did things like:
info_TEXINFOS = texinfo.txi info-stnd.texi info.texi
DISTCLEANFILES = texinfo texinfo-* info*.info*
# Do not create info files for distribution.
dist-info:
@:
in order not to distribute .info files.
Now that we have the 'info-in-builddir' option that explicitly causes
generated '.info' files to be placed in the builddir, this hack should
be longer necessary, so we deprecate it with runtime warnings. It is
scheduled to be removed altogether in Automake 1.14.
* automake.in (handle_texinfo_helper): Raise proper runtime warnings
if the hack is triggered.
* NEWS: Update.
* t/txinfo28.sh: Adjust.
* t/txinfo23.sh: Likewise.
* t/txinfo25.sh: Adjust and extend.
* t/txinfo24.sh: Likewise.
User can now ask info files to be built in the $(builddir), rather than
the $(srcdir), by specifying the Automake option 'info-in-builddir'.
This feature was requested by the developers of GCC, GDB, GNU binutils
and the GNU bfd library. See the extensive discussion about automake
bug#11034 for more details.
OK, to be honest, having '.info' files built in the builddir was
*already* possible, but only using ugly and undocumented hacks involving
definition of the CLEANFILES and/or DISTCLEANFILES. For example, the
binutils project did something like this in the relevant 'Makefile.am':
# Automake 1.9 will only build info files in the objdir if they are
# mentioned in DISTCLEANFILES. It doesn't have to be unconditional,
# though, so we use a bogus condition.
if GENINSRC_NEVER
DISTCLEANFILES = binutils.info

tests: don't always look for a C++ compiler named 'RCC'
On MacOS X (10.8), since the file system is case-insensitive, RCC
can point to the "Resource Compiler" of the Qt4 Toolkit:
<http://doc.qt.digia.com/4.2/rcc.html>
That mismatch causes our configure script to erroneously think that
no working C++ compiler is present, and that is thus necessary to
skip all the test cases requiring such a compiler.
So only look for a compiler named 'RCC' if the file system is
case-sensible.
Issue spotted analyzing the testsuite logs reported in bug#13317.

Issue spotted perusing the testsuite logs reported in bug#13317.

docs: autom4te cache can break CONFIGURE_DEPENDENCIES

obsolete: better error message if AM_PROG_CC_STDC is used
In Automake 1.13, the long-deprecated (since 2002) macro AM_PROG_CC_STDC
has been removed. Such a removal, albeit sensible and justified, was
probably done in a too-abrupt way, since it didn't turn the pre-existing
warning messages into fatal error messages, but simply dropped the macro
definition, so that remaining usages of it would cause unclear error
messages, e.g.:
configure.ac:4: warning: macro 'AM_PROG_CC_STDC' not found in library
from aclocal, and:
configure.ac:4: error: possibly undefined macro: AM_PROG_CC_STDC
If this token and others are legitimate, please use m4_pattern_allow.

In Automake 1.13, the long-deprecated macro AM_CONFIG_HEADER (deprecated

the removal was done without a proper deprecation period, and that
caused packages upgrading to Automake 1.13 to fail with very unclear
error messages, e.g.:

ylwrap: various fixes
Rename properly header guards in generated header files, instead of
leaving Y_TAB_H.
Convert header guards in implementation files. Because ylwrap failed
to rename properly #include in the implementation files, current
versions of Bison (e.g., 2.7) duplicate the generated header file in
the implementation file. The header guard then protects the
implementation file from duplicate definitions from the header file.
Generate header guards with a single '_' for series of non alphabetic
characters, instead of several. This is what Bison does.
Makes the test t/yacc-d-basic.sh pass again.
* lib/ylwrap (guard): Properly honor $1 to rename properly the
header guards.
Keep a single _ instead of several.
(rename_sed): Rename as...
(sed_fix_filenames): this.
Suggested by Stefano Lattarini.
(sed_fix_header_guards): New.
Use it.
