--- Comment #14 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Jonathan Wakely from comment #4) > 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>>. Although it's still present on the branches. Do we want to fix it there too?
