* 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.
