[antlr-interest] Antlr emit vs Qt emit

[Jim Idle]

Please see the archives. You should:

a) Probably not include both ANTLR and QT headers in the same space - you
should not be mixing code in with ANTLR code I think;
b) If you must do this, and I can't see why you must, as you should call
external helper methods from actions, then undef emit before including the
antlr headers.

But, the answer is to decouple your code really.
