--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to William Throwe from comment #2) > This warns if passed an array of length 0 because the for-loop condition is > always false.

You can use N != 0 && i < N which doesn't have the overflow problem, but I agree it doesn't make the code clearer, and should not be necessary.
