ok, I think the conclusion is that this is a bug and it should set
errno; now there's an implementation problem that it's a macro and
stdio.h isn't allowed to include errno.h.

I guess we can generate a third copy of the declaration of __errno,
but I'd sort of rather not; it should really go in its own .h file
somewhere, but we don't have a place for that (support/? bits/?) and
adding one requires a bikeshedding round first.
