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