cygwin_attach_handle_to_fd is an interface intended for use with a user-level
program that wants to associate an existing *windows handle* with a cygwin fd.

If you are trying to add functionality to cygwin to allow fd passing
then you shouldn't be using this function.  It is not intended for use
with cygwin-specific things like unix-domain-sockets.  Those really
exist only in the cygwin domain and they are already associated with an
fd.

If you are attempting to do this as a user program rather than as a modification
to the cygwin DLL, then you are probably out-of-luck.
