You could also make all your token regular expressions accept all
possible cases. So if `int' were a keyword to lex, your regexp might
be "[iI][nN][tT]". You could (easily?) write something that would
accept a keyword regexp and give you back a case-insensitive keyword
regexp.
It looks like you might have been asking for case-insensitive
comparison for your keyword hashtable. This is quite easy, just by
using a HashedType with a case-insensitive `compare' function.
