 * Revision 1.8  2002/11/02 15:12:06  lucifer
 * Integrated RElf's changes (with small mods) from fix2.zip
 *
 * Revision 1.8  2002/10/25 17:44:13  RElf
 * CONST, INVCONT, MAXDELTA, MSBMASK now defined here
 *
 * Revision 1.7  2002/01/21 19:41:29  lucifer
 * Change by RElf:
 * added MSB(x) macro definition
 *
 * Revision 1.6  1997/09/18 18:21:08  lucifer
 * moved global type definitions into "pkctypes.h" (D. Bragin)
 *
 * Revision 1.6  1996/09/06 11:48:23  bragin
 * moved global type definitions into "pkctypes.h"
 *
 * Revision 1.5  1996/08/21 17:37:20  conrad
 * memory for plain- and ciphertext is now allocated dynamically
 *
 * Revision 1.4  1996/08/13 13:20:27  conrad
 * Increased value of KEY2SPACE after several complaints. Now the array is
 * 32 MB...
 *
 * Revision 1.3  1996/06/23 10:28:48  lucifer
 * Modifications for DJGPP 2.0: DJGPP can't handle arrays larger than 16MB,
 * so key2i is now allocated dynamically.
 * DJGPP doesn't know about type ushort, either.
 *
 * Revision 1.2  1996/06/12  09:47:20  conrad
 * Release version
 *
 * Revision 1.1  1996/06/10 17:55:27  conrad
 * Initial revision
