To put that in a more positive light: we like to think that our code is
Posix-compliant and runs in a Posix-compliant environment. We're not
thrilled about introducing non-Posix-isms for the convenience of one
platform ... especially if there's no easy way to enforce that the
nonstandard coding convention be used.

Back on track: if rename() does exist under Windows then my idea is
unreliable. Any other thoughts? How about #including <io.h> in port.h
(for Windows only of course) before we #define these things?
