It's true. In the portable UDP stack which Epilogue sells, I
originally had defined the header length and IP version numbers at
bitfields but finally took them out because we found that that
bitfield ordering was really compiler dependent instead of processor
dependent. I replaced our bitfields with appropriate masking
operations to avoid the problem.
