I don't think I've tried that in this century ;-). Between the sheer
size of the grammar and the fact that we're already depending on the
behavior of several arcane %-options, I really doubt any tool besides
bison will work. Besides, the whole point of shipping the built files
in tarballs is to ensure no one has to use any other tool.
