I think both cases (overflow and wraparound) should have warnings.

 
You're free to think that, of course, but wraparound behavior is well
defined and unambiguous.  I wouldn't mind an *optional* warning, but
plenty of programmers might deliberately write something like
 
    const unsigned int max = -1;
 
with the reasonable expectation that it will set max to INT_MAX.
 

(cough) UINT_MAX (cough)
