 /* 

  * 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, Utrix and those with smaller default integer

  * sizes than 32 bits.  For all such environment, we fall back to using

  * BIGNUM.  We may need to fine tune the conditions for systems that

  * are incorrectly configured.

  *

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

  * (2) DTLS, for sequence number manipulation.
