   --  Note: although the functions in this package are in a sense Pure, the
38

47
   --  with the array starting at address Right of length Right_Len.

   --  The comparison is in the normal Ada semantic sense of array
49
   --  comparison. The result is -1,0,+1 for Left<Right, Left=Right,
50
   --  Left>Right respectively. This function works with 4 byte words
51
   --  if the operands are aligned on 4-byte boundaries and long enough.
