If you actually had (expression != 'b0), that would force the expression to be evaluated at a width of 32 bits (if it were itself narrower) and unsigned. But again, this is taking the equivalence too literally. The semantics of "if (expression)" are those of self-determined evaluation of expression, followed by a comparison of that value with a zero of equivalent width to the result, or more simply, a check for any 1 bits.
