/* 

 * The purpose of this header file is for supporting 64-bit integer

 * manipulation on 32-bit (and lower) machines.  Currently the only

 * such environment is VMS.  Other environments that do not natively

 * support 64-bit integers can safely use the code developed for VMS.

 *

 * The only clients of this code are (1) pqueue for priority, and

 * (2) DTLS, for sequence number manipulation.
