I have checked in the changes to move to JavaCC 3.0, which is now available
(or of course you shouldn't need it just to build).
I see no real changes in 3.0. However It does generate a different stream
reader class. I recall discussion of some optimizations of the older JavaCC
generated ASCII reader class a while back, but I never investigated these.
If you're working with the 1.3 branch (head) from CVS please let me know
if you see any problems.
