This is fine, assuming that we have 32 bits CPU, and sizeof(unsigned
long) equals 4. So 4*16=64.  There is no guarantee that on some archs
unsigned long is going to stay 32 bit width. When it's either longer
or shorter (I am not sure if long can be 16 bits long, but possibly
ANSI C standart doesn't say anythin about it's length in bits).

In ANSI C the basic types are not defined in terms of bits, however
there is a minimum magnitude required.  An unsigned long is supposed to
hold at least 4294967295, which is 2^32-1.  On most normal platforms,
that means an unsigned long must be at least 32 bits.

I don't speak for anybody but myself - that's enough trouble.
