bitfields: how to cast (int) into a bit field?

[idallen at watmath.UUCP]

How does one cast an integer into, say, a 6-bit bit field in such a
manner that LINT won't complain "conversion may lose accuracy"?

How does one create a typedef for a bit field, such that one might use
it to perform the above cast?
