{    This procedure deletes the client rpc segment if one exists.  This allows
{ freeing extra pages associated with the segment.  The segment was sent from
{ the client by the DFP$SEND_CLIENT_RPC_SEGMENT request.  The server request
{ then used DFP$RECEIVE_CLIENT_RPC_SEGMENT to obtain a pointer to the segment.
{ When done reading the segment the server request should use
{ DFP$DELETE_CLIENT_RPC_SEGMENT to remove the segment.
