- Get all functions prototyped or at least defined before use. - Make code compile (Mostly) clean with -Wall set - Start to reduce the degree to which DES aka libdes is built in. - get all functions to the same uniform standard of definition: int foo(a, b) int a; int *b; { : } - fix numerous bugs exposed by above processes. Note - this replaces the previous work which used an unpopular function definition style.
