Like I said, on the wire it is 16-bits.

Yeah, it seems strange, but I have a test program here that shows it is 
32-bits application-side for proxies/stubs. If the upper 16-bits are 
non-zero then the proxy code throws a RPC_X_ENUM_VALUE_OUT_OF_RANGE 
exception. I don't know whether it is the same for type libraries, but 
it really needs testing.
