 Seems a known issue (hopefully someone (Jason?) will deal with it soon!):

>Organization:
>Environment:
ix86-linux
>Description:
In the following testcase, member i of Foo is not brought to scope by the using declaration, instead g++ reports:

bellatrix:~/src/tests$ g++-3.4 -c using3.cpp -Wall
using3.cpp: In member function `void Bar<T>::foo()':
using3.cpp:11: error: `i' has not been declared

this works with both 3.2 and 3.3 (in fact, they dont care if I omit the using declaration, too, but in whole this is a regression).

template <class T>
struct Foo {
        int i;
};

template <class T>
struct Bar : public Foo<T> {
        using Foo<T>::i;
        void foo()
        {
                i = 0;
        }
};

int main()
{
        Bar<int> bar;
        bar.foo();
        return 0;
}
