Okay; though I think that my list of assumptions is easier to check directly for any given implementation: it corresponds exactly to items 2 and 4 in C99 J.3.5, and any conforming C implementation is required to explicitly document how it behaves with regard to these items. I'm not sure how to decide which particular consequences should be listed, but those for &, |, ^ and ~ could certainly be included.
