NEWS: IRIX is still supported; only SGI C compiler depcomp no longer is
This change is for the maint branch.
The only IRIX-specific support that is going to actually be removed in
the next major Automake versions is the depcomp support for the SGI
compiler. That means that automatic dependency tracking will no
longer work with that compiler, but "normal" compilation should still
work, at least until the compiler is supported by Autoconf.
So there is no point in alarming our users by stating in the NEWS file
that "support for IRIX and the SGI compilers is going to be removed";
after all, while we don't test on nor particularly care about IRIX
anymore, that doesn't mean we are deliberately breaking it, and the
likelihood of an intended breakage there is very low.
* doc/automake.texi (The Types of Distributions): Here,
cross-reference "List of Automake options" rather then
the more generic node "Options". Improve wording while
at it.

tests: avoid a spurious failure when running inside Emacs
Some versions of Emacs set the environment variable 'EMACS' to 't'
for child processes. Thus, when running from inside Emacs, "$(MAKE) -e"
erroneously allows the 't' to override the one in the Makefile.
* t/lisp-flags.sh: Unset var 'EMACS', fixing the issue.
compat: reinstate AM_CONFIG_HEADER and AM_PROG_CC_STDC
Make them give runtime warnings in the obsolete category, but apart
from that, make them behave as they did in Automake 1.12.x and earlier.
While removing those macros seemed quite harmless, because it didn't put
a real burden on the developers (requiring them just to do a quick edit
to configure.ac), it turned out to place an unsustainable burden (or at
least, a burden perceived as such) on distro packagers who use the latest
Automake to bootstrap existing packages. Many of those packages, while
having likely updated to AC_CONFIG_HEADERS in their development version,
still used AM_CONFIG_HEADER in their existing released versions, and the
removal of this macro would have thus forced the Fedora packagers to
patch all of them. References:
In addition, the Fedora packagers have already decided to patch their
Automake 1.13.1 to reinstate the AM_CONFIG_HEADER and AM_PROG_CC_STDC
macros (plus other macros that I don't believe it's worth worrying about):
So, rather than having one more incompatibility floating around, we
better mirror that change (or, actually, its relevant parts) in the
upstream.

docs: serial-tests are not deprecated, just discouraged
We don't plan to remove support for them, nor to have the serial-tests
option give any kind of runtime warning, so don't alarm the users
still using serial tests with pointless "deprecation" or "obsolescence"
warnings.

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.

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.

should have been used instead. Set IFS to ':' before looping on the

docs: autom4te cache can break CONFIGURE_DEPENDENCIES

just document it ...

Do so for several Texinfo-related tests. Note that some of such tests
with suboptimal names are *not* renamed; that's because they are going
to be removed in the master branch anyway (since they check from some
soon-to-be-removed features), so renaming them would be wasted work,
and could even create useless merge conflicts.

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.

* t/list-of-tests.mk: Add it.

obsolete: better error message if AM_CONFIG_HEADER is used
In Automake 1.13, the long-deprecated macro AM_CONFIG_HEADER (deprecated
since 2002) has been removed in favour of AC_CONFIG_HEADERS. However,
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.:
configure.ac:4: warning: macro 'AM_CONFIG_HEADER' not found in library
from aclocal, and:
configure.ac:4: error: possibly undefined macro: AM_CONFIG_HEADER

tests: better names for temporary configure.ac files
When editing a pre-existent 'configure.ac' file in a test script, name

default name for the Autoconf input files throughout the testsuite.

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

Keep a single _ instead of several.

inherit that in configure.ac.

* t/subpkg-macrodir.sh: ... in this test. And fix some typos that would
