00068  * The purpose of this header file is for supporting 64-bit integer
00069  * manipulation on 32-bit (and lower) machines.  Currently the only
00070  * such environment is VMS, Utrix and those with smaller default integer
00071  * sizes than 32 bits.  For all such environment, we fall back to using
00072  * BIGNUM.  We may need to fine tune the conditions for systems that
00073  * are incorrectly configured.
00074  *
00075  * The only clients of this code are (1) pqueue for priority, and
00076  * (2) DTLS, for sequence number manipulation.
