+       portability: fix pointer arithmetic to conform to C standard.
+       Reported by Tys Lefering at
+       <http://lists.gnu.org/archive/html/bug-bison/2010-03/msg00035.html>.
+       This fix is already implemented in glr.c and does not apply to
+       lalr1.java.
+       * data/lalr1.cc (yy::parser::parse): Increase size of
+       yyerror_range and adjust subscripting so you don't have to
+       subtract one from the beginning of the array.
+       * data/yacc.c (b4_declare_parser_state_variables,
+       yyparse, yypush_parse): Likewise.
