[cfe-dev] dependent name related question

[guoqing zhang]

Hi ,

Can somebody explain why I need "typename" before Y<alignof(X)>::type  in
the following piece of code ?

template<int N> struct Y { typedef int type; };

template<int N> void h() {
      struct  X {};
      typename Y<alignof(X)>::type z;
}

Y<alignof(X)>::type is non-dependent, isn't it ?

Regards
