Not if you link to the ANTLR v3 binaries. Only if you wish to include the
ANTLR v3 sources in a GPL'ed program. You need to re-license to satisfy the
GPL requirement that all derivative works (of a GPL-licensed work) must also
be GPL. Actually that should be "must also be available under the GPL". They
may be simultaneously available under other licenses.
