And strictly speaking, C bitfields are completely useless for that
purpose since the compiler is free to use whatever method he wants for
allocating bit fields.  So if you want to write a portable program,
you are back to making the masks yourself.

Where bit fields work reliably is when you are not interchanging data
with other applications, but just laying out your internals.
