Hum. Well, that's an embarrassment to me, since I was the one who
ported that patch over from Craig McPheeters' fork of Perforce Jam.
It's supposed to speed up builds by cacheing dependency information,
(but of course if you're deleting the file it won't have any effect).
However, I never vetted the code for correctness and I haven't tried
to find any updates from its author since May 2002. Craig, any news?
