Options supported by gcc aren't making this easy - the way I hoped to fix this doesn't work.

jtn in patch #4421:

> I've noticed that whenever I get a -Werror build failure from
> my (GCC 4.6.3) toolchain, I get an additional complaint about
> this warning option


> cc1: error: unrecognized command line option "-Wno-tautological-compare"


> it only happens if the build was going to fail anyway

The last point is the problem exactly. When configure tests if the compiler supports the option, compiler does not complain.
