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.
