Done in the attached revised patch, which also fixes the bug Ulrich Müller 

I also don't understand why you unconditionally removed this program
from the Windows builds and installations: the problem with setgid
doesn't exist on Windows, so nothing should prevent Windows
installations from having this program, right?

It's more the other way round. On platforms without setuid/setgid, Emacs can use its already-existing code to update the score file itself. The auxiliary program is needed only on platforms that have setuid/setgid, to avoid the security problems that would ensue if we made Emacs itself setuid/setgid.
