So, bizarrely, here's what I have found.

The distributed screen 4.3 binary has the problem (no scrollbar, etc.)
The distributed screen 4.2 binary does not have the problem
Installing the 4.2 src package, running cygport and running the result
does not have the problem
Installing the 4.3 src package, running cygport and running the result
_does not have the problem_.

This despite the fact that (by chance, as you will see in a moment) the
distributed and locally-built 4.3 binaries are the same size.

But they are not in fact identical, and the visible differences, per
"strings", is as follows:

This is at least _suggestive_ that your compilation environment and mine
are in some way different.

Does

  #define TERMINFO 1

occur in your build/config.h ?
