--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
C++98 version which shows it is a regression and it started to fail between GCC
4.1.2 and 4.4.7:
```
namespace X 
{ 
    struct type {}; 
}
namespace Y 
{ 
    typedef int type;
}
using Y::type;
using X::type;
int i = sizeof(type); //gcc and msvc accepts this but clang rejects this

```
