screen 3.7.4 is not working properly on alpha. You cannot for example do Ctrl-a w to see how many windows are open. Solutions: screen-3.7.2 compiles and work correctly.
Works on Intel arch, but not on alpha. Does create new screens, but not able to do <Ctrl>-a w to see list, etc.
Screen 3.7.6 appears functional on alpha. Recompile from the source rpm in Raw Hide rpm --rebuild screen-3.7.6-1.src.rpm and install the binary rpm if you need the fix.
