  34   32-bit operations
  35   The octet order is screwy.  words are LSB first (LS octet, actually), but
  36   longwords are MSW first.  For example, 0x12345678 is encoded 0x5678 in the
  37   first word and 0x1234 in the second.  When looking at the data as stored in
  38   the COFF file, you would see the octets ordered as 0x78, 0x56, 0x34, 0x12.
  39   Don't bother with 64-bits, as there aren't any.
