I don't know where we stand on this. It was previously necessary to have the
cast because otherwise NULL would only get passed as an integer, not a pointer
(long). We have fixed NULL in our headers, but the cast may still be the
correct incantation for some systems. I think the best approach is to delete
casts in other more obvious places, but leave these alone for now.
