16	History:
17
18	Modified by cmetz for OPIE 2.32. Added symbolic flag names for
19		opiepasswd(). Added __opieparsechallenge() prototype.
20	Modified by cmetz for OPIE 2.31. Removed active attack protection.
21	Modified by cmetz for OPIE 2.3. Renamed PTR to VOIDPTR. Added
22		re-init key and extension file fields to struct opie. Added
23		opie_ prefix on struct opie members. Added opie_flags field
24		and definitions. Added more prototypes. Changed opiehash()
25		prototype.
26	Modified by cmetz for OPIE 2.22. Define __P correctly if this file
27		is included in a third-party program.
28	Modified by cmetz for OPIE 2.2. Re-did prototypes. Added FUNCTION
29                definition et al. Multiple-include protection. Added struct
30		utsname fake. Got rid of gethostname() cruft. Moved UINT4
31                here. Provide for *seek whence values. Move MDx context here
32                and unify. Re-did prototypes.
33	Modified at NRL for OPIE 2.0.
34	Written at Bellcore for the S/Key Version 1 software distribution
35		(skey.h).
