static void dosum ( )

static

     Some executable formats have timestamps in the first 16 bytes, yuck.  

     Iterate over full file contents.  

         We read the file in blocks of BLOCKSIZE bytes.  One call of the
         computation function processes the whole buffer so that with the
         next round of the loop another block can be read.  

         Read block.  Take care for partial reads.  

         If end of file is reached, end the loop.  

         Process buffer with BLOCKSIZE bytes.  Note that
                        BLOCKSIZE % 64 == 0

     Add the last bytes if necessary.
