Larry,

I think the G3 and G4 compression formats have an implicit
assumption about what is white and what is black.  This may have
led Microsoft to ignore the photometric tags.

Folks have done it, but I don't know the details.  You might
want to look around the MingW project.  I think they may
provide cross compilers.
