But -Wconversion generates other undesirable and unavoidable
warnings,
so you probably can't use it.
Oh yeah, forgot about that one. In gcc >= 4.3 the 'other undesirable

So -Wconversion is probably exactly what is called for.
Hopefully we'll see it in Apple's gcc fork one day! Greg, is a
radar needed?
Kill^WFile them all, and let the compiler team sort them out!
