Just to throw it in: I'd probably do it with semantic predicates that
do some manual lookahead (with calling LA() and comparing that to the
individual suffixes you have).

Then you can force ANTLR to take specific ways through your lexer  
alternatives.

I think on of the examples in the distribution does something  
related, and I'm
sure the list archives also have something like this.

HTH,
-k

P.S.: Sorry for the terse posts, I'm in a hurry... :)
