+       Compute at M4 time some of the subtractions.
+       * data/lalr1.cc (b4_substract): New.
+       (b4_rhs_data): Use it.

+
+       symbol::token.
+       This is allows the user to get the type of a token return by
+       yylex.
+       
+       * data/lalr1.cc (symbol::token): New.
+       (yytoknum_): Define when %define lex_symbol, independently of
+       %debug.
+       (yytoken_number_): Move into...
+       (symbol::token): here, since that's the only use.
+       The other one is YYPRINT which was not officially supported
+       by lalr1.cc, and anyway it did not work since YYPRINT uses this
+       array under a different name (yytoknum).

+       * TODO (YYERRCODE): Mention the case of $undef.
