[antlr-interest] Context-Sensitive Follow Sets.. Bug?

[Andrey Desyatov]

Sorry, Jim for the confusing question.
I've tried to continue thread from May with subject "Context-Sensitive
Follow Sets.. Bug?"
(http://www.antlr.org/pipermail/antlr-interest/2010-May/038776.html),
but without success (it was my second post to mailing list and I
couldn't understand how to continue any thread).

Description of my problem I've given in another thread:
http://www.antlr.org/pipermail/antlr-interest/2010-September/039764.html.

Any help would be appreciated.

Kind regards,
Andrey
