REM This is an inordinately troublesome piece of code, particularly because it
REM tries to work on both Win9x and WinNT-based systems. If we could abandon '9x
REM support, things would be much easier, but sadly, it is not yet time.
REM Be cautious about editing this, and only add WinNT specific stuff in code that
REM only runs on WinNT.
