They're wrong. The only constraint on the size of long (and I may be making this up) is that sizeof(short) <= sizeof(int) <= sizeof(long) (presumably the proprietary-but-about-to-be-standard long long will have the constraint of sizeof(long) <= sizeof(long long), but here I AM making things up.)
____ david parsons \bi/ sizeof long == 32 bits? Oh, my, those authors are \/ going to have an expensive portability lesson.
