--- Comment #5 from Jeff Hammond <jeff.science at gmail dot com> --- Can someone tell me where the appropriate place to define __STDC_NO_ATOMICS__ and __STDC_NO_THREADS__ in GCC so I can submit a patch? I'd rather solve the problem and take 1-2 steps forward towards C11 compliance rather than debate the philosophical aspects of the problem.
