  5. ** Created: 2/17/90 RLR **
  6. ** Revised: 12/27/90 SRD,AJ,BSK,JT Reference C version **
  7. ** Revised (for MD5): RLR 4/27/91 **
  8. ** -- G modified to have y&~z instead of y&z **
  9. ** -- FF, GG, HH modified to add in last register done **
  10. ** -- Access pattern: round 2 works mod 5, round 3 works mod 3 **
  11. ** -- distinct additive constant for each step **
  12. ** -- round 4 added, working mod 7 **
