I'm a little dubious about whether -Og is a case we should pay special
attention to?  Our standard optimization setting for gcc is -O2, and
once you go away from that there are any number of weird cases that
may or may not produce warnings.  I'm not entirely willing to buy
the proposition that we must suppress warnings on
any-random-gcc-version combined with any-random-options.
