Yes, I agree that's very important. In fact, I'd like to generalize
that to say that -- as much as possible -- the same code should generate
the same warnings across architectures, optimization levels, and
releases as well. If -O3 causes us to say "might have been
uninitialized, but we removed it" while -O0 just says "uninitialized"
that's probably OK. But, having warnings not appear at -O0, or go away
completely with higher levels of optimization isn't good.
