It does not *really* matter as much here, as that file defines that `DEBUG` constant if it has not yet been defined, but yes, it assumes that *if* it is defined, then it is set to `1`. Which is the case, but it is fragile. I changed it locally already, and it will be part of the next iteration. Thanks, Johannes
