Use poll with Windows socket

Use poll with Windows socket

[Biswapriyo Nath]

I've tried to use poll() with a Windows socket (from WSASocket) and a
cygwin side file descriptor (fd). But it is only signaled for fd only.

At first, I have seen that fhandler_socket_wsock::set_socket_handle() casts
SOCKET to int. So, is it possible to use poll() with the SOCKET type? Or Is
there any magic to convert Windows socket to cygwin fd and vice-versa?

No, you can't do that.  The Cygwin poll call requires a Cygwin socket,
otherwise all the bookkeeping stuff fails.
