[antlr-interest] adding "version" option to ANTLR grammars

[C. Mundi]

You're on to something good.

As a newcomer, I started using the alpha builds of antlr3 and immediately
ran into the exact problem you are trying to solve.  I appreciate the
legitimate concerns raised by others here.  But anything which provides a
clue about the assumptions under which a grammar was written would be
helpful.

Thanks.
