--- Comment #10 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I see no implementation (MSVC, GCC, clang) implements this at all.
Here is an example where GCC produces an assembly failure:
```
namespace a {
   extern "C" void f(void){}
}

namespace {
  extern "C" void f(void) {}
}

int main(void)
{
  f();
  a::f();
}
```

It might be handle to implement this even correctly too.
