not useful -Wsign-compare warning involving % operator
Another case where the feature would be useful:
extern int
f(short s, unsigned int u)
{
return s == u % 100;
}
It would be nice if the compiler noticed that rhs is always within 0..SHRT_MAX,
so the comparison is not surprisingly affected by integer promotion.
