Akim Demaille 609b3d8096 calc++: rely on Automake.
Rely on $(YACC) being the bison being built, and let Automake do the
rest.  It turned out to be much more difficult than anticipated, for
various reasons, including some bad behavior from Automake 1.11.2
which (i) generates calc++-parser.h instead of calc++-parser.hh, and
(ii) leaves an #include "y.tab.h" in the generated parser instead
of #include "calc++-parser.h".

The authors of Automake appear to be aware of the problem,
http://lists.gnu.org/archive/html/automake/2011-05/msg00008.html
so a simple work around will suffice for the time being.

	* examples/calc++/y.tab.h, examples/calc++/calc++-parser.hh: New.
	To work around Automake 1.11.2 issues.
	* examples/calc++/local.mk: Remove all the rules for compilation
	with bison, leave them to Automake.
	So provide it with "calc++-parse.yy" as a source file.
	(calc_sources_generated, calc_sources_extracted): Rename as.
	(calc_generated, calc_extracted): these.
	(calc_sources): New.
	Fix them.

	* src/local.mk (YACC, AM_YFLAGS): Move to...

Akim Demaille 360ae94ebc maint: de-recurse the handling of examples
The directory was still using a local Makefile.am because it provides
"scoped" Make variables: these examples are not meant to use the same
CPPFLAGS etc.  If we were to use the same -I set, we'd pick up
gnulib's stdio.h for instance, which we do not want for these simple
examples.

Yet, as a result, the dependencies are less accurate, there is code
duplication, etc.  This is especially perceptible when trying to
extract more examples from the documentation, as will be done in
forthcoming changes.

In order to make the tuning of CPPFLAGS easier, discard the predefined
-I from Automake.

	* examples/calc++/Makefile.am: Rename as...
	* examples/calc++/local.mk: this.
	Adjust the paths which are now rooted in top_srcdir/top_builddir.
	Handle BISON_CXX_WORKS here, instead of the too crude previous
	approach that completely discarded the whole directory.
	($(BISON)): Remove now useless bouncing recipe.
	(calc___CPPFLAGS): New.
	Stay away from -Ilib.
	* Makefile.am, configure.ac, examples/local.mk,
	* examples/calc++/test: Adjust.

	* configure.ac: Pass nostdinc to Automake.
	* src/local.mk, lib/local.mk (AM_CPPFLAGS): Move to...
	* Makefile.am: here.

	* src/local.mk, examples/calc++/Makefile.am (BISON, BISON_IN): Factor
	to...
	* Makefile.am: here.
	* tests/local.mk: Use it.

Jim Meyering e187b40d31 do not ignore errors like ENOSPC,EIO when writing to stdout
Standard output was never explicitly closed, so we could not
detect failure.  Thus, bison would ignore the errors of writing
to a full file system and getting an I/O error on write, but only
for standard output, e.g., for --print-localedir, --print-datadir,
--help and some verbose output.
Now, "bison --print-datadir > /dev/full" reports the write failure:
bison: write error: No space left on device
Before, it would exit 0 with no diagnostic, implying success.
This is not an issue for "--output=-" or the other FILE-accepting
command-line options, because unlike most other GNU programs,
an output file argument of "-" is treated as the literal "./-",
rather than standard output.
* bootstrap.conf (gnulib_modules): Add closeout.
* src/main.c: Include "closeout.h".
Use atexit to ensure we close stdout.
* .gitignore: Ignore new files pulled in via gnulib-tool.
