We don't tend to like #ifery in C files.
Why is it required?
And why not just put them were they're consumed?

How often are you realistically going to enable these? Can you do
without them and just add some printks when debugging? Seems a shame to
dirty the code-base with seldom used / questionably helpful LoC.

Stage 3 what?
Perhaps some simple function headers would help?
