A minor quibble, and ... I don't think it's even a minor quibble, and I don't think it even needs to be argued. It's quite clearly _not_ the program which defines those constants, but the implementation. After all, if you compiled the same source code with different options, you'd get a different result. That the implementation gets the value of its implementation-defined constants from the command line rather than from an options file or from its own internal code, _that_ is a minor quibble; it is still perfectly evident that it _is_ the implementation which defines them, and not the source under translation.
