--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
It should be possible to detect the wide-spread 'i < i + 1' anipattern in the
front ends without too many false positives (with __builtin_warning it should
even be able to avoid them in dead code).  Let me confirm this request on that
basis.
