preproc.c: prevent the compiler from reducing enum pp_token_type

The compiler is free to store enum pp_token_type into any size integer
small enough to contain all the values up to 2^n-1 for the smallest n
which contains all the values.  Force it to size it to integer size,
since we use it to hold macro positional parameters.
