Comment 31 for bug 1669578

@LocutusOfBorg, I can give you a screen 4-5.1-3 compatible patch based on the Debian package.
One thing to note is that even my compat-layer patch will be of no help once {Debian,Ubuntu} breaks the message protocol which they eventually *will* have to do. Upstream screen uses at least message version 5 whereas {Debian,Ubuntu} use message version 2. Once you bump the message version previous screen versions will break. But updating the message protocol will be unavoidable in the long run. So you should consider warning users and start breaking backward compatibility at some point in the near future. :)
