I think we have had a discussion along this line before. I am against fixing warnings from this option, because those changes would hide errors if a variable's type changed from signed to unsigned or vice versa, which could happen because of refactoring or it might be dependent on system headers. FWIW, clang has the same warning on by default. There, it's called -Wtautological-compare. I'm less concerned about -Wempty-body, but I can't see the practical use either way.
