| * 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. |
