[antlr-interest] Semantic predicate hoisting - How to turn off? (somewhat urgent)

Hi!
In ANTLR 3 is the new semantic predicate hoisting feature turned on by
default?
I believe it is, because I'm getting javac errors like:
[21:47:11] \tmp\antlrworks\pclParser.java:4225: cannot find symbol
[21:47:11] symbol : variable f
[21:47:11] location: class pclParser
[21:47:11] if (
(((evalPredicate(we,"$we.is_l_value")&&evalPredicate(f,"$f.is_l_value"))||evalPredicate(we,"$we.is_l_value")))
) {
when in fact "$we.is_l_value" and "$f.is_l_value" never appear in the
same rule. Either that or am I doing something fundamentally wrong :-) .
There were literally dozens of similar errors that disappeared as soon
as I added the option "k=1;". Is there a similar option to disable
predicate hoisting and any other advanced features ANTLR may have
enabled by default?
I need to get this working within the week, so I'll greatly appreciate
any help you can offer me!
