funny, in perldoc -f unpack we have : 
     For example, the following computes the same number as the Sys-
     tem V sum program:

               $checksum = do {
                  local $/;  # slurp!
                  unpack("%32C*",<>) % 65535;
              };

So it gained one more bit in the meanwhile :)
