48 The octet order is screwy. words are LSB first (LS octet, actually), but
49 longwords are MSW first. For example, 0x12345678 is encoded 0x5678 in the
50 first word and 0x1234 in the second. When looking at the data as stored in
51 the COFF file, you would see the octets ordered as 0x78, 0x56, 0x34, 0x12.
