Very few programs are strictly conforming, and IMHO the concept of
strict conformance isn't all that useful. For example, this program is
not strictly conforming:
#include <stdio.h>
#include <limits.h>
int main(void) {
printf("%d\n", INT_MAX);
}
I don't believe a conforming hosted implementation would be allowed to
reject it.

4p3:
A program that is correct in all other aspects, operating on correct
data, containing unspecified behavior shall be a correct program and
act in accordance with 5.1.2.3.
