We fixed this warning in upstream dhcpcd. We ship with GCC that is typically 2 major versions behind upstream GCC and this at least discourages handling generic issues directly with upstream and upstream has little interest in reiterating over old branches for corner cases that are generally speaking unimportant. So overall I disagree with the request. Feel free to contribute a patch to GCC or find someone in GCC to fix it (we have no resources to do it on our side) so we can remove the cast.
