- * 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.
