--- Comment #5 from Jeff Hammond <jeff.science at gmail dot com> --- Indeed, _Atomic is a language keyword and doesn't require any headers (the inclusion of stdatomic.h in this code is superfluous), so the "header->explicit library" argument doesn't apply. In any case, I do not see why language intrinsics that require headers should require libraries. Why is sqrt() from math.h different from fprintf() from stdio.h? Maybe POSIX requires that, but ISO C11 doesn't, and I'm using -std=c11 not -std=posix. --as-needed would greatly enhance user experience for both this and libm.
