Some changes made to the bsp code in early November
(to stop gcc compiler warnings) caused segfaults when
performing intersections (and possibly while doing other
boolean operations). I felt it was best to revert these
changes (I also got rid of the DOS line terminators in
the files). Some more info about the matter can be found
in the first 10 or so posts for Novembor on the old
mailing list:
