compile error (with minimal but complete example)

[monarch_dodra]

template <typename T>
struct trait
{
    template <typename U>
    static void foo()
    {}
};

template <typename T>
class myClass
{
public:

    void bar()
    {
        trait<T>::foo<bool>(); //error: expected primary-expression before 'bool'
                               //error: expected ';' before 'bool'
    }
};

int main()
{
    myClass<bool> a;
    a.bar();
}

Using code::blocks + MinGW 4.5
Works fine with vs2008.

I'm at a loss. I expect some obscure C++ rule hiding template foo unless it is qualified in some way, but I just can't seem to figure it out...
