--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The header is included since r13-2677-g0abc63a5ea4550 (and
r12-9342-g0cec4e9cd44e25 on the branch), and not including it would mean not
being able to annotate atomic<shared_ptr<T>>.

I agree with Andrew, this is a bug in libsanitizer. The correct way to use
__has_feature in a public header is to test with #ifdef __has_feature not to
define the fallback definition.
