(union yyalloc, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):

Do not define if yyoverflow is defined, or if this is a C++ parser and
either YYSTYPE or YYLTYPE has nontrivial constructors or destructors.
(yymemcpy) [! defined YYSTACK_RELOCATE]: Do not define; not needed.
(yyparse) [! defined YYSTACK_RELOCATE]: Do not relocate the stack.
