 * 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.
