I'm learning Antlr (version 2.7.7) and cannot figure out how to 
disambiguate a simple grammar: 

programmatic_unit 
        : simple_name a b
        ;

a 
        : (STAR simple_name )*
                (SLASH simple_name)*
        ;

b 
        :
                ( (STAR) 
                        INT)?
        ;

simple_name 
        : NAME_FRAG 
        ((SPACE)? NAME_FRAG)*
        ;

The generator complains that the "a" rule above is nondeterministic upon 
STAR. I understand (I think) why -- when matching programmatic_unit/a, it 
is ambiguous whether to use "a" or "b" when STAR is the next token. But 
how do I repair the grammar? Any advice would be very welcome. 

Thanks, 
Mike
