From: Matthew Bettencourt <[EMAIL PROTECTED]>
Removing -64 may not be enough. I've no idea what the effect of
defining SIXTY_FOUR_BIT_LONG is in a 32-bit environment. Maybe that
should be changed to THIRTY_TWO_BIT_LONG as well? Otherwise, there
may be times where testing for zero doesn't work because something
else missed half the words and therefore never turned the bignum to a
zero, or something like that.
I know what I say is pretty vague, but I've just started playing with
64-bit vs. 32-bit myself, and haven't quite seen or analysed all the
effects of getting the bignum details wrong...
