Sorry, just realised that this the VARIANT_UserMarshal function is in
oleaut32. On Windows, this calls WdtpInterfacePointer_UserMarshal for both
the VT_UNKNOWN and VT_DISPATCH cases, which in turn calls
CoMarshalInterface.

I hope this helps,

Thanks, I didn't know about those functions. Unfortunately I can't see
the prototypes anywhere, and don't really have time right now to
disassemble native code to find out. I'll have a look today and see what
the best way of dealing with this situation might be....
