Suck a cock, fool. The only thing that is assumed there is the endianness of 4-byte integers in the file, which is generally specified by the format!

The only thing wrong with the code in >>18 (why doesn't /prog/ have IDs anymore?) is that it should declare the buffer to be exactly 4 bytes long -- since the file format defines uints as 4 bytes. It's subsequently converted to an unsigned int in the return -- see the shifts and ors?
