[antlr-interest] [antlr-dev] ANTLRWorks ANTLR embedding

[Jamie Penney]

I figured out why it wouldn't compile ANTLRWorks - the 'prepare-osx' 
target did not specify if="is-macos". Adding that fixed that build for me.

For a bit of additional information on my actual problem, it throws the 
following exception when I call Generate in ANTLRWorks. I have examined 
the Grammar source and it does not have the method ANTLRWorks is looking 
for.
