It's better to be lax for normal users trying to build the puzzles from source to actually run them. That way, warning changes in some particular compiler I haven't seen yet won't break the build. Instead, I've invented a cmake setting -DSTRICT=ON which turns on all those flags. So I can build with them myself, to ensure the code is as portable as possible. And that flag is set in Buildscr, so that my official builds won't complete until that warning mode is satisfied.
