Utter BS.

This gets into the simple (but most certainly NOT simplistic :-) issue of
the licensing of co-mingled code which mostly devolves to an issue of how
the various licenses deal with derivative works.

The GPL's viral nature would infect the co-mingled, derivative work but
would have absolutely no effect upon the licensing of the individual parts.
If, as the example was asking, the licensing of the ANTLR code (runtime and
generated) had restrictions on co-mingled, derivative works then you could
NOT actually apply the GPL without violating such a license.  In the case
of reality, ANTLR's license is extremely permissive (i.e., currently public
domain which means that anybody can "steal" it and otherwise treat it as
their own) but eventually it will be a BSD-alike which would continue to
apply even if you created a co-mingled, derivative work.

IANAL, GCPLA.

Take care,
