Resolve invalid type Int which will cause syntax errors. Here are the relevant snippets from my local copy of the headers:

_com_ptr_t Relational Operators

Line 385-393

    bool operator==(int null) const
    {
        if (null != 0)
        {
            _com_issue_error(E_POINTER);
        }

        return m_pInterface == nullptr;
    }

Line 450-458

    bool operator!=(int null) const
    {
        if (null != 0)
        {
            _com_issue_error(E_POINTER);
        }

        return m_pInterface != nullptr;
    }
