standard x86:
---LSB-- ---2SB-- ---3SB-- ---MSB-- [bytes] LITTLE_ENDIAN
M765432L M765432L M765432L M765432L [bits] ?_BITFIELD

(Not sure what bitfield type, but I'd guess BIG_ENDIAN_BITFIELD)

standard sparc:
---MSB-- ---3SB-- ---2SB-- ---LSB-- [bytes] BIG_ENDIAN
M765432L M765432L M765432L M765432L [bits] ?_BITFIELD

(I hope I got these two right)


Theoretical machine with BIG_ENDIAN but LITTLE_ENDIAN_BITFIELD:
---MSB-- ---3SB-- ---2SB-- ---LSB--
L234567M L234567M L234567M L234567M
