 *
 * We eventually realized that we could write more portable
 * code if we decoupled any association between the 'C' types
 * and the external types. (XDR has this association between the 'C'
 * types and the external representations, like xdr_int() takes
 * an int argument and goes to an external int representation.)
 * So, now there is a matrix of functions.
