d31bd24b40 configure: when performing a compiler feature test for a -Wno-foo flag, attempt
to use -Wfoo instead of -Wno-foo. This works around a bug in some versions of
gcc, where it will silently accept an unknown -Wno-foo option, but will
generate an error for a compile which uses -Wno-foo if that compile also
triggers any warnings.

9993a3aebb Enable -Wcovered-switch-default again, but add -Werror to the checks to make
sure we don't use it with compilers that don't support it.
