  15 # DES_PTR       use pointer lookup vs arrays in the DES in crypto/des/des_locl.h

  17 #               dependancies but needs to more registers, good for RISC CPU's
  18 # DES_RISC2     A different RISC variant.
  19 # DES_UNROLL    unroll the inner DES loop, sometimes helps, somtimes hinders.
  20 # DES_INT       use 'int' instead of 'long' for DES_LONG in crypto/des/des.h
  21 #               This is used on the DEC Alpha where long is 8 bytes
  22 #               and int is 4
