You don't have to enable warnings, but most c programmers do.
The problem is, what proportion of 2^32 in C are correct? I'm will to bet it is as close to 0 as doesn't matter. The gcc devs aren't stupid, before enabling a warning like this, they will run a test compiling a substasal chunk of debian, and see if there are any false positives.
