Indeed, it would seem to me that implementing a version of fcntl on
Windows would be flat out insane -- surely the sensible thing to do
would be provide two implementations of whatever it is you need, the
unix one of which calls fcntl.

The interface "design" of the fcntl syscall is not something that begs
to be spread around...
