Well, as the person who proposed the -Wdisabled-optimization
warning, let me say that I'm proposing that it *not* be invoked
by any "group" warning flag like -Wall.  You don't claim that
it is, but readers might (reasonably, but falsely) infer that
from what you wrote.

I'd just like to have this optimization information so I can change the
generated C code I'm handing to gcc if I have to.
