This is unnecesary. The Windows event loop coded into Emacs already
receives Alt-F4 in a single event. What is needed is to determine from
that event loop if there is a binding for Alt-F4 (created with *-set-key
etc). Once we know that there is no such binding, it is trivial to send
back the Alt-F4 event back to Windows.
