Being from EBCDIC land, s390 probably also has an unsigned char by default. (dang this is dumb - all Linux ports should use the same default) There's also endianness, but that would affect many more architectures. Alignment seems to be the same between ppc and i386. (not that I would know or care about bitfields)
