Ok... I was planning to make big-endian versions of the structs so

bits out of
a word using the lower bits first.
The C standard explicitly allows it to be implementation defined.
Having been bit by this exact problem, I can also recommend never
using bitfields for anything other than things kept solely in local
memory.
Yeah, I just read that paragraph in K&R... sigh. Bitfields make the code so
readable, though :) Anyway, I'll rewrite it to use good old shifting and masking.
