They should be found in the same way as A is found in gunc::X definition. IIUC the following paragraphs from the std apply. 9/2 3.4/3 10.2/2 14.2/6 14.6.1/2a They basically say that the name of a base class is in the scope of the derived class. I.e. you can refer to it using an unqualified-id no matter in what namespace the base class name is declared. I can provide full-text citations if needed. >How-To-Repeat: # 1 "namespace.cpp" # 1 "<built-in>" # 1 "<command line>" # 1 "namespace.cpp" namespace hunc { struct A {}; template <class T> struct B { }; } namespace gunc { typedef hunc::B<int> Ybase; struct X : hunc::A { A* a; }; struct Y : hunc::B<int> { B<int>* b; }; struct Z : hunc::B<int> { B* c; }; } int main() { } >Fix: >Release-Note: >Audit-Trail: >Unformatted:
