Two buildworld+buildkernel cycles later, and everything still seems just
peachy.  Seems to work, too, although the base GCC still complains that
'z' and friends are unknown type conversion characters - that's just
because GCC 2.x doesn't speak C99.

If there are no objections in the next few days I'll commit it.
