	Besides the stuff you mentioned above, you also will need to
handle any uses of the # or ## operators.  Perhaps something more.
But you're right, it wouldn't be insurmountable.

	IMHO, the issue isn't whether you *can* do it.  The question I
have is *why* would you do it?  IIRC, K&R support is only so people
can bootstrap the C compiler.  Don't we want to encourage people to
compile g77 with gcc (preferably the gcc they just bootstrapped?)
