* data/lalr1.java: Capture the declarations as m4 macros to avoid
duplication. When push parsing, the declarations occur at the class
instance level rather than within the parse() function.
Change the way that the parser state is initialized. For
push-parsing, the parse state declarations are moved to
"push_parse_initialize()", which is called on the first invocation of
"push_parse()". The %initial-action code is also inserted after the
invocation of "push_parse_initialize()".
The body of the parse loop is modified to return values at appropriate
points when doing push parsing. In order to make push parsing work,
it is necessary to divide YYNEWSTATE into two states: YYNEWSTATE and
YYGETTOKEN. On the first call to push_parse(), the state is
YYNEWSTATE. On all later entries, the state is set to YYGETTOKEN. The
YYNEWSTATE switch arm falls through into YYGETTOKEN. YYGETTOKEN
indicates that a new token is potentially needed. Normally, with a
pull parser, this new token would be obtained by calling "yylex()". In
the push parser, the value YYMORE is returned to the caller. On the
next call to push_parse(), the parser will return to the YYGETTOKEN
state and continue operation.

* tests/local.mk: Prefer passing variable assignment by
the command line, instead of the environment, so that it
is reported in the logs.
Prefer single quotes for shell literal strings.
* tests/local.at: Go for colors.
(--compile-c-with-cxx): New option.
We used to pass "CC=$CXX" as command line argument,
but it was not possible to adjust CFLAGS accordingly
in atlocal, since it is loaded before assignments on
the command line are honored (so that the command line
takes precedence).
* tests/atlocal.in: Implement it.
* tests/local.mk: Use it.
* tests/local.mk (check_SCRIPTS): Add atlocal and atconfig so
that they are properly updated before running tests.
(RUN_TESTSUITE_deps): New.
Use it to factor the dependencies of "*-check" targets,
especially those that don't bounce to the regular
"check-local" target, since then they don't benefit from the
proper dependencies (such as atlocal).
The directory was still using a local Makefile.am because it provides
"scoped" Make variables: these examples are not meant to use the same
CPPFLAGS etc. If we were to use the same -I set, we'd pick up
gnulib's stdio.h for instance, which we do not want for these simple
examples.
Yet, as a result, the dependencies are less accurate, there is code
duplication, etc. This is especially perceptible when trying to
extract more examples from the documentation, as will be done in
forthcoming changes.
In order to make the tuning of CPPFLAGS easier, discard the predefined
-I from Automake.
* examples/calc++/Makefile.am: Rename as...
* examples/calc++/local.mk: this.
Adjust the paths which are now rooted in top_srcdir/top_builddir.
Handle BISON_CXX_WORKS here, instead of the too crude previous
approach that completely discarded the whole directory.
($(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.
* tests/local.mk (TESTSUITE_AT): Include plackage.m4.
Adjust dependencies.
Make testsuite.at its first argument.
(package.m4): Be silent.
(testsuite): Be silent.
Use $<.
This change was made by applying emacs' untabify function to
nearly all files in Bison's repository. Required tabs in make
files, ChangeLog, regexps, and test code were manually skipped.
Other notable exceptions and changes are listed below.
* bootstrap: Skip because we sync this with gnulib.
* data/m4sugar/foreach.m4
* data/m4sugar/m4sugar.m4: Skip because we sync these with
Autoconf.
* djgpp: Skip because I don't know how to test djgpp properly, and
this code appears to be unmaintained anyway.
* README-hacking (Hacking): Specify that tabs should be avoided
where not required.
* tests/local.mk: Replace "cd && testsuite" by "testsuite -C".
Solves problems when top_srcdir is an absolute path.
Suggested by Eric Blake.
* configure.ac: Require Autoconf 2.62.
* tests/local.mk (tests/atconfig): The rule was incorrect, but
remove it: now that there is no tests/Makefile.am, the top-level
Makefile properly updates atconfig when needed.
TESTSUITEFLAGS is barely readable.
* tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)
for backward compatibility.
Use the former instead of the latter.
* tests/Makefile.am: Rename as...
* tests/local.mk: this.
* Makefile.am, configure.ac: Adjust.
* Makefile.am (DISTCLEANFILES): Define.
(maintainer-check, maintainer-xml-check, maintainer-push-check):
Remove, we no longer need to bounce to the real targets.
