You still need to handle the attribute like qualifiers ....

The above is not the reason why namespaces are not handled in GCC's C++
front-end. The reason why they are not handled in C++ is because you need to
handle them in overloads and templates correctly. Does clang handle those
correctly or does it ignore that issue?
