I agree that C bit operators are obvious enough, although that may be a
per-project style preference issue.  With the bit operators, noone has
to look at whatever the macro may expand to, especially that every
project might define its unstandard wrapper...  Moreover, the macros
aren't necessarily shorter or more readable, and they result in less
portable code.  It seems that KNF doesn't have a suggestion about it

But I don't have a strong opinion about this.
