`malloc' has no way of knowing what type you are going to store in the
memory, and the (unsigned long *) bit is just a cast (for more info on which
see a C book).

Incidentally, you should also check in each case whether `malloc' returns
NULL, because you don't really know how much memory is available. It might
be less than (64K * 4 * 10).
