Thanks very much.  I have applied your patch with one small change:

> +  buf = (unsigned char *)bfd_malloc (0x800000);

I replaced the use of a magic number in the malloc, and subsequent
read, with a #define'd value:

   buf = (unsigned char *) bfd_malloc (COFF_CHECKSUM_BUFFER_SIZE);

It just makes it easier to change the buffer size, should that
become needed in the future.

Cheers
