Scott, this patch causes compilation to fail for me with:

>
> Valgrind reports a leak coming from the flex parser generated code.
> The flex-generated lexer allocates memory to use for its state stack.
> Examining this code it is clear that once allocated, the stack is never
> freed. Since I cannot easily replace flex code, I inserted the code to free
> the stack as a lexer rule.
> Valgrind is happy with the result.
