Akim Demaille + + * src/gram.h, src/gram.c (error_token_number): Remove, use + errtoken->number. + * src/reader.c (reader): Don't specify the user token number (2) + for $undefined, as it uselessly

coded 2. + (Even though this 2 is not the same as above: the number of the + undeftoken remains being 2, it is its user token number which + might not be 2). + * src/output.c (prepare_tokens): Rename the `maxtok' muscle with + `user_token_number_max'. + Output `undef_token_number'. + * data/bison.simple, data/bison.c++: Use them. + Be sure to map invalid yylex return values to +
