Thanks for this.

It's a good idea, even though I am allergic to yacc and had hoped
never to see another yacc parser as long as I live.  One of the
advantages of a hand written parser would be to get something we can
debug.

However, a more practical question: this code is GPL, but I don't know
if we can incorporate it into gcc without copyright assignment.  Maybe
someone who understands FSF policy could tell me.

Andrew.
