yes but the relevant question for the not officially static integer constants is "in what precision are those operations to be performed in? I assume that you choose gcc types for these operations and you expect the math to be done within that type, i.e. exactly the way you expect the machine to perform.
As I explained in an earlier message, *within* a single expression, we are free to use higher precision, and we provide modes that allow this up to and including the usea of infinite precision. That applies not just to constant expressions but to all expressions.
