There are two endianesses (?) at play here--in the bit stream and on the
platform. To which are you referring? If the latter, there isn't
anything to worry about because ibitstream makes no assumptions about
the endianess of the platform, but it does assume network order, or big
endian, in the bit stream. If you are concerned about the bit-stream
endianess, we'd need to work out the specifics, because I don't think
the semantics would be obvious for other endians. For example, can the
bit endianess be specified separate from the byte endianess? (Hmm...
that's reminds me--it currently supports STL bitsets but I don't think
it supports C bitfields. I'll have to look into that.) Also, what
bit-stream endianesses should bitstream support--big, little, mixed, middle?

Like I said, it should already behave the same on all platforms, but
maybe I'm missing something. What is your specific concern?
