| // as inline, as a strange way of providing something like a using-directive. |
| // Clang has an egregious hack to work around the problem, by allowing a |
| // namespace to be converted from non-inline to inline in this one specific |
| // case. |
| |
| // the last 4.6 release was 2013, so the hack is removed. This checks __atomic |
| // is not special. |
