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.
