(hmm, does this even compile? I didn't think C allowed variable

The pStubDesc structure should have been initialized (including setting
that pointer, I think) by the NdrClientInitialize or
NdrClientInitializeNew (or for DCOM, NdrProxyInitialize, but perhaps
NdrProxyInitialize should call down to NdrClientInitialize/New anyway)
functions. My patches didn't implement those functions, since I was mostly
concerned with DCOM. Is this a real RPC app that works on Windows you're
working on?
