I don't think you need to have that deep an understanding to do the above
(add error checking to cygwin_attach_handle_to_fd), or to add the subject
ioctls (in fhandler_serial::ioctl).  You shouldn't need to stray far
outside those functions I would think.

Don't bother if you can't follow through with the assigment paper work.
Your patch will probably not be accepted without it.  Just trying to save
you some pain if you didn't understand that.

Ok, then the comment below is void as long as you continue to use that
version.  The NtCreateFile issue is also void unless you are working with
snapshots or CVS sources.
