The reason the limit is 32500 is that the offsets into the table
are shorts. To make tables larger than 32767 work, you will have
to change a bunch of shorts to ints or longs.


At the time I wrote Berkeley Yacc, machines had such small memories
that using shorts instead of ints was a big plus. Times change.
