Thanks! I see that I was on the wrong track...

Does it help to change lines (which I think I've typed correctly this
time) as follows?

Line 474, add `/null':

                           [pItf _IUnknown-pointer/null]

Line 621, remove `cast':

         (define csi (make-COSERVERINFO 0 machine #f 0))
