Now I remember why we have typecasts embedded in the swrite() macro... I
figure we should make something similar to that for sendto() too.

Seems like there should be some sort of autoconf magic to deal with this kind of stuff....I could look down that avenue unless you have some experience that says not to.
I'll try installing the mingw cross-compiler on my linux box so I can at least see the problem.
