include them even if we also happen to have included system RPC headers, as we want *our* versions of the structures (which use types with explicit sizes for structure members, as we use them for on-the-wire data). Change pmap_prot.h to prefix all #defines and structure names with "SUNRPC_" or "sunrpc_", to avoid collisions with any definitions and structure names from the system header files.
