'Fraid to say, if you can't figure this one out then you need to visit
cygwin mailing lists to see if screen has been ported by someone else. This
version isn't gonna work OOTB.

Fwiw, you need to modify the conditional at 616 such that setenv(a,b,c) is
invoked instead of setenv(a,b). Exactly which macro is debatable.
Ordinarily one would use __unix__ but without in depth knowledge of screen
itself you've no idea if such will break the test for other platforms. Thus
you'll have to play safe and tag __CYGWIN__ on there instead.

If something else blows up, well like I said, you're screwed doing it
yourself! :-|
