I have recently begun to work with Berkeley yacc, and have
a grammar put together for a small mathemtical language for
my application.

I need to add two particular things to the grammar, which I
am not sure how to do properly. Are there repositories of
sample grammars around for me to examine? I have found a
C grammar on the web, but couldn't tell much from it.

Specifically, I need to
    1) allow for an if/endif and if/else/endif construct.
    2) allow lists in a declaration, i.e, instead of allowing
          only a declaration like
                double a;
          also allow
                double a,b,c,d;

If anyone knows of some good yacc samples, I would really
appreciate any pointers!
