No one said that, AFAIK.

ANSI says nothing about bits however. All I'm saying is that we
can't make the "assumption" that signed ints go from -2B to +2B
because ANSI doesn't allow that. ANSI says all you can assume is
that they go from -32k to +32k (+/-). Making any kind of assumptions
on bit sizes can lead to trouble. If you need a *guaranteed* larger
range, it's up to the program to determine the right type:
#if INT_MAX <= 32767
typedef bigrange_t long
#else
typedef bigrange_t int
#endif
In practicle, real-world matters, I doubt if the assumption that
ints are +/- 2B will bite us at all.
