The current patch only effects the C front-end (and ObjC, as I believe
it also uses c-tree.h).  I have separate patches for C++, but I wanted
to get the C patches checked-in first, since the C++ patches require
separate approval.

But I guess I might as well re-test the C++ patch, and submit that
as soon as I've done that, without waiting for approval on the existing
patch.
