There doesn't seem to be any reason for the special member of struct
token to be unsigned; AFAICT it is only ever being directly compared
to explicit characters and the SPECIAL_* enum constants using ==, !=
and in a switch statement. Making it plain int avoids an annoying
warning from match_op in token.h when compiling with -Wsign-compare.
