Hi,

I have a grammar with an ambiguity that I just can't resolve.  When I check
the grammar using AntlrWorks I get the following: "Decision can match input
such as "{EOF, OPEN}" using multiple alternatives: 1, 2".  I've attached a
screen grab of the syntax diagram generated by AntrlWorks.  I don't
understand why ANLTR is thinking that EOF is ambiguous with OPEN.  I've
checked the grammar and clif_file is the only rule that is not referenced
from within the grammar, so I don't think that ANLTR should see module as a
start rule.  Any help is much appreciated.
