Thanks for the input on this. I can't really use the pointer solutions,
so my current fix is to define YYSTYPE as a struct, rather than a union,
and to pass around classes in the struct. This seems to work well,
though it's inefficient.
The reason that reference counting is required here is that the lexer
produces a token class, rather than AST nodes, and a single token might
eventually appear multiple times (or not at all) in the AST.
Thanks -
Evan
