// libstdc++ 4.6.x contains a bug where it defines std::__atomic[0,1,2] as a
|
||
|
|
// non-inline namespace, then selects one of those namespaces and reopens it
|
||
|
|
// 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.
