No specific suggestions, but you might want to search the archives of a couple of Apple lists: Scitech - <http://lists.apple.com/mailman/listinfo/scitech> Unix-porting - <http://lists.apple.com/mailman/listinfo/unix-porting> (I know you're not porting from unix but a lot of compiler discussions come up there.) And if you don't come up with anything it's definitely worth posting to scitech - lots of helpful people. TimH -- G-Books is sponsored by <http://lowendmac.com/> and...
