Can you still unlink opened files on Windows 9x, Windows NT, and W2K
with this change?  I believe that is why I removed this.  Either that
or it prevented files from being opened.  Sorry that I don't remember.

If the above still works, then I'll put this back and comment this
so we won't have to guess next time.
