__STDC_NO_THREADS__ is defined in glibc's stdc-predef.h because it
describes combination compiler and library properties.
The correct fix for atomics for 4.9 will be to implement them - see

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 complia

__STDC_VERSION__ describes *intent* of command-line options (as regards

If GCC doesn't support C11, it should not claim to support C11 via
__STDC_VERSION__. The C11 standard definition isn't a recommendation from
which implementers can pick and choose based upon their priorities.

I don't know whether Andrew intends stdatomic.h to go in GCC or glibc, but
in any case I consider this a duplicate of bug 53769, which in turn I
don't really consider a useful bug report at
