| Yes, they're modulo types, that's why this is NOT an error,

The argument was that it makes sense to issue a warning when the the
code is dubious -- not just an error.  However, in this case, modulo
arithmetic for unsigned int is a characteristic propery.
Consequently, it does not make much sense to warn about it.
