Currently we define enumerators only for symbols that have an identifier. That rules out tokens such as '+', and nonterminals such as foo-bar and foo.bar. As a consequence we are taking chances: the compiler might compile yysymbol_type_t as too small an integral type for some symbol codes. * data/skeletons/bison.m4 (b4_symbol_sid): Forge a unique symbol identifier for symbols that don't have an ID.
