ComSmartPtr...: cannot access private member

I can’t compile juce_win32_direct2DGraphicsContext.cpp, from the latest tip. I have installed the Windows 7 SDK, set JUCE_DIRECT2D to 1 in juce_Config.h, and tried to build. The errors are numerous, and all the same. They have to do with operator& being private in ComSmartPtr:

d:\juce_tip\src\native\windows\juce_win32_direct2dgraphicscontext.cpp(37) : error C2248: 'ComSmartPtr<ComClass>::operator &' : cannot access private member declared in class 'ComSmartPtr<ComClass>'
        with
        [
            ComClass=ID2D1Factory
        ]
        d:\juce_tip\src\native\windows\juce_win32_nativeincludes.h(249) : see declaration of 'ComSmartPtr<ComClass>::operator &'
        with
        [
            ComClass=ID2D1Factory
        ]

Yeah, none of the Direct2D stuff is public code yet, it’s not finished!
