一个弱智错误

今天写代码脑袋进水了，

class Singleton
{
public:
    static Singleton* GetInstance();
private:
    Singleton() {}
    static Singleton *m_pIns;
};
Singleton *Singleton::m_pIns = NULL;
Singleton* Singleton::GetInstance()
{
	if (m_pIns == NULL)
		Singleton *m_pIns = new Singleton;
	return m_pIns;
}

第13行的Singleton *应该去掉
