[Bug c++/30821] New: [4.1.2 Regression] templates and typedefs cause function prototype not to match

[sschunck at pdf dot de]

the following compiled fine on gcc-3.4.6 but gives error on gcc-4.1.2

error: prototype for 'typename A<T>::B::type A<T>::B::f()' does not match any
in class 'A<T>::B'
error: candidate is: typename A<T>::type A<T>::B::f()
error: template definition of non-template 'typename A<T>::B::type
A<T>::B::f()'


template < typename T > 
class A 
{
        typedef int type;
        class B;
};

template < typename T >
class A<T>::B
{
        typedef typename A<T>::type type;
        type g() { return 0;}
        type f();
};

template < typename T >
typename A<T>::B::type 
A<T>::B::f() { return 0; }

( I have no vanilla gcc available, so hopefully gentoo guys did not screw up
gcc-4.1.2 )

Using built-in specs.
