[SECURITY] please withdraw screen 4.5.0 from the Cygwin archives

[Andrew Schulman]

Can someone please remove screen 4.5.0-1 from the archive?

screen 4.5.0 has at least one serious security problem [1], and maybe some other
bugs too. I doubt Cygwin is affected, since screen doesn't rely on root
privileges there. But 4.5.0 is only a minor update and a fix isn't going to be
available until next month, so I think I want to withdraw this release.

Thanks,
Andrew
