- --------------------
- 01i,22sep92,rrr added support for c++
- 01h,26may92,rrr the tree shuffle
- 01g,26feb92,wmd added #pragma align 1 to align properly data structures.
- 01f,23feb91,del removed useless checking and typedef of u_int32 as u_long.
- 01e,24oct90,shl deleted redundant function declarations.
- 01d,05oct90,shl added ANSI function prototypes.
- made #endif ANSI style.
- added copyright notice.
- 01c,30apr90,gae fixed definition of u_int32 -- dependent of compiler define.
- 01b,26oct89,hjb upgraded to release 4.0
