--- Comment #2 from Nikolas Klauser <nikolasklauser at berlin dot de> --- Shouldn't -Wconversion also enable -Wsign-conversion? -Wconversion sounds to me like it should diagnose all conversions, especially since it's the same kind of bug I want to catch by enabling the flags. In which case would I be interested in different sizes but not different signs?
