scope of template-inherited members

[filip.konvicka]

Hi, I'm having problems with the following code:

template<typename T> struct A {
T i;
};

template<typename T> struct B : public A<T> {
void access_i() { i; }
};

g++ 4.2.2 complains that

'i' was not declared in this scope

in B<T>::access_i() definition. Of course, when I use

void access_i() { A<T>::i; }

everything's OK, but I don't see why I need to use this. Can anyone
please explain why this is?

The code compiles fine with MSVC, and I'd like to keep the code
readable...

Thanks,
Corn

To answer myself... this is because of C++ standard's [temp.dep]/3,
and the following suffices:

void access_i() { this->i; }

Sorry for the noise.
