* src/muscle_tab.h (MUSCLE_INSERT_LONG_INT): New.

Browse Source 
* src/output.c (output_table_data): Return the longest number.
(prepare_tokens): Output `token_number_max').
* data/bison.simple, data/bison.c++ (b4_sint_type, b4_uint_type):
New.
Use them to define yy_token_number_type/TokenNumberType.
Use this type for yytranslate.
* tests/torture.at (Big triangle): Push the limit from 124 to
253.
* tests/regression.at (Web2c Actions): Adjust.
