 * What's going on here? Well, it's like this. When the service
 * is being compiled it wants to have the service definition specific
 * info included, and when the client is being compiled it wants that
 * info. This includes the appropriate file which was generated by
 * make in the protocols directory (probably /usr/include/rpcsvc).
 *
 * Uhm... guys? With RPC, you aren't supposed to have seperate
 * server-specific and client-specific header files. You have one header
 * file that's suitable for both. If your code doesn't work using just
 * the one header file, I submit to you that it's broken.
