I tried applying the patch and building on Windows and...  er...
nothing happened?  That is, touching w32.c didn't lead to anything being
compiled.  So I guess I don't understand how this works under Windows.
(A mingw/non-mingw thing?)

I still think it would be very nice if we had UDP support under Windows,
so if somebody else could poke at this, that'd be cool.
