I'm a maintainer of Homebrew (a macOS package manager) and we're trying to build packages on the newly released macOS 11.0 and its counterpart Xcode 12 release. GNU Screen v4.8.0 fails to build:

configure: checking select with  -lnet -lnsl...
configure: error: !!! no select - no screen

and later

configure: error: !!! no tgetent - no screen

Upon investigation, it seems like it fails because Clang 12 requires functions to be defined before use.

There exist some patches elsewhere that fix this by `include`ing the right headers, for example, this set from MacPorts: https://github.com/macports/macports-ports/commit/38df2ef467d4bcce657e8b8d36735c1fc9bb64eb.
