This is pretty much what I thought, but it does beg one question - why
does Microsoft's viewer obey the Photometric flag in the original, but
not the tiffcp created tiff?

Also, this is less related to libtiff, but does anyone have any
pointers on how I might cross-compile libtiff+tools for windows under
linux?

Thanks!
