Is it really necessary to have everything in the header twice rather than
using endian switches in the I/O ?

Also with the code in that form how do you build a single copy of the
driver that runs on platforms which may have one or the other endian

Finally - we have defines for bitfield direction - because the compiler
has a lot of latitude in which way around it packs bitfields.
