adding the != does not make the conditional clearer to me.  in fact
it just make it harder to read.  however, it probably not a good
idea to do assignments in places where someone might not expect to
see them.  the alternative something like this:

        while (1) {
                a = b;
                if (a == 0)
                        break;
        }

but its not very pretty either.
