         It depends on whether you need two different programs or is  
content with one,
         able to do two different pareses. In the former case, you  
need to somehow create
         two different .y files; in the latter, you might try  
introduce some runtime
         start-tokens into a single grammar. The Bison FAQ may have  
something about it.
