  67  * The purpose of this header file is for supporting 64-bit integer
  68  * manipulation on 32-bit (and lower) machines.  Currently the only
  69  * such environment is VMS, Utrix and those with smaller default integer
  70  * sizes than 32 bits.  For all such environment, we fall back to using
  71  * BIGNUM.  We may need to fine tune the conditions for systems that
  72  * are incorrectly configured.
  73  *
  74  * The only clients of this code are (1) pqueue for priority, and
  75  * (2) DTLS, for sequence number manipulation.
