BTW, the same is true for the Ruby version, and the definition HIDDEN=99
is missing also. Since you can't debug in ANTLRWorks without a compatible
skip(), I have this at the top of my grammars:

@lexer::members {
        # The Ruby template lacks skip(), but the WS rule below needs it for ANTLRworks
        def skip; @channel = 99; end
}

I hope that helps someone. Perhaps the same thing is feasible in the C
version, as a work-around?
