8 * Most 64-bit platforms use 'long', while most 32-bit platforms use '__u32'.
9 * Yes, they differ in signedness as well as size.
10 * Special cases can override it for themselves -- except for S390x, which
11 * is just a little too special for us. And MIPS, which I'm not touching
12 * with a 10' pole.
