  +) Make DES key schedule conform to the usual scheme, as well as correcting

     its structure.

  +) Make DES key schedule conform to the usual scheme, as well as

     correcting its structure. This means that calls to DES functions

     now have to pass a pointer to a des_key_schedule instead of a

     plain des_key_schedule (which was actually always a pointer

     anyway).

     [Ben Laurie]



  +) Enhanced support for IA-64 Unix platforms (well, Linux and HP-UX).
