ce05140d9d Require Autoconf 2.59, and don't include local.at twice since 
Autoconf 2.59 yells about it for some reason.

3dc4c5faa9 (Torturing the Scanner): Don't use \x0 or \0 in 
Bison tokens, as this runs afoul of the 2003-10-07 change that
disallowed NUL bytes in character constants or string literals.

603f1cfdc5 * config/announce-gen, Makefile.cfg: New.

cd3684cfa8 When reducing initial empty rules, Bison parser read an initial 
location that is not defined.  This results in garbage, and that
affects Bison's own parser.  Therefore we need (i) to extend Bison
to support a means to initialize this location, and (ii) to use
this CVS Bison to fix CVS Bison's parser.
* src/reader.h, reader.c (epilogue_augment): Remove, replace
with...
* src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
* src/parse-gram.y: Adjust.
(%initial-action): New.
(%error-verbose): Since we require CVS Bison, there is no reason
not to use it.
* src/scan-gram.l: Adjust.
* src/Makefile.am (YACC): New, to make sure we use our own parser.
* data/yacc.c (yyparse): Use b4_initial_action.

473013144d Have lalr1.cc catch with Paul Eggert's patch to fix the infinite 
error recovery loops.  This patch is based on
<http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
Also, augment the similarity between lalr1.cc and yacc.c.
Note: the locations of error recovery rules are not correct yet.
* data/lalr1.cc: Comment changes to augment the similarity between
lalr1.cc and yacc.c.
(YYERROR): Goto to yyerrorlab, not yyerrlab1.
(yyerrlab1): Remove, but where it used to be (now the bottom part of
yyerrlab), when hitting EOF, pop the whole stack here instead of
merely falling thru the default error handling mechanism.
(yyerrorlab): New label, with the old contents of YYERROR,
plus the following change: pop the stack of rhs corresponding
to the production that invoked YYERROR.  That is how Yacc
behaves (required by POSIX).
* tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
fail.

1f7a61ff99 Tune local.at so that people can "autom4te -l autotest calc.at -o 
calc" for instance, to extract a sub test suite.
* tests/testsuite.at: Move the initialization, Autotest version
requirement, and AT_TESTED invocation into...
* tests/local.at: here.
* tests/testsuite.at: Include it for compatibility with Autoconf
2.57.
* tests/Makefile.am ($(TESTSUITE)): Report that the warning should
be ignore.
