63 /* |
|
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. |
