Yes, that's the problem.

I don't know about that one, I imagine it could create some strange 
problems because there are already a lot of preprocessor defines and 
tests in parse.y which normally just get copied into the resulting c file.

How about doing something like this in the Makefile, before feeding the 
file to non-bison yaccs:

   sed '/^%token/ s/"[^"]*"//'

Of course parse.y would have to be modified to declare just one token 
with the %token declaration, not a whole lot.

Thoughts?
