+       * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
+       Avoid subscript error in yycheck.  Bug reported by Andrew Suffield in
+       <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
+       * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
+       Check for malloc failure, for consistency with yacc.c.
+       (yytname_size): Remove, for consistency with yacc.c.
+
+       The bug still remains in data/lalr1.cc, as I didn't have time
+       to fix it there.

+
+       * configure.ac (GXX): Rename as...
+       (CXX): this, to keep the original Autoconf semantics.
+       Require 2.57.
+       * data/lalr1.cc: Fix b4_copyright invocations.
+       If YYDEBUG is not defined, don't depend upon name_ being defined.
+       (location.hh): Include string and iostream.
+       (Position::filename): New member.
+       (Position::Position ()): New.
+       (operator<< (Position)): New.
+       (operator- (Position, int)): New.
+       (Location::first, Location::last): Rename as...
+       (Location::begin, Location::end): these, to mock the conventional
+       iterator names.
+       (operator<< (Location)): New.
+       * tests/atlocal.in (CXX): New.
+       * tests/testsuite.at (AT_COMPILE_CXX): New.
+       * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
+       locations in a more synthetic way.
+       (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
+       lalr1.cc is used.
+       Adjust the C locations to match those from Emacs: first column is
+       column 0.
+       Change all the expected results.
+       Conform to the GCS: simplify the locations when applicable.
+       (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
+       (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
+       these CPP macros with the m4 macros new defined by...
+       (AT_CHECK_PUSHDEFS): this, i.e.:
+       (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
+       (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALSm AT_LEX_PRE_ARGS)
+       New macros.
+       (AT_CHECK_POPDEFS): Undefine them.
+       (AT_CHECK_CALC_LALR1_CC): New.
+       Use it for the first lalr1.cc test.
