That is not how it works. Not sure whether such approach would work at all. But that still doesn't solve the PR I mentioned because sending -Wfoo through the option machinery does not turn options enabled by Wfoo into errors. Even worse, what do you suggest for -Wno-error=foo? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43687
