No.

C type rules still mandate the promotion of the signed argument to
unsigned.  Which means that if you do not know for a fact that the
signed argument is non-negative, you still have a problem.  Which
you can't know without data-flow analysis, and the warning is based
simply on the existance of the promotion.

Make 'i' a size_t like it ought to have been in the first place.
