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