Hmm. True. But even so, it's still not right on my system, which doesn't
use 8-bit bytes. (It's word addressable where each word can contain any
value, so sizeof(int) == sizeof(double) == sizeof(char) == 1.)
Should there, then, be another symbol to define the number of bits in a
byte, distinct from the number of bits in a char?
