Is there any reason why I can't specify an initial value for a static field
of a templated class?

template <typename T>
class X {
public:
    static int n;
};

template <typename T>
int X<T>::n;

void main()
{
    X<int> t;
    cout << t.n;
}

This works fine, but if n is given an initial value:

template <typename T>
int X<T>::n = 1;

then the linker complains that X<int>::n is an undefined symbol.

What am I missing here?
