That's not C++ ... or what is it, the preprocessor?

Did you make it work "in the simplest case"?
Do that, so you know it works _at all_, if it does you can add
complexity all day every day.
I made it work two times:
https://dataswamp.org/~incal/emacs-init/gnus/browse.el (simple)
https://dataswamp.org/~incal/emacs-init/buffer-menu.el (???)
They work, 100% is all I'll say.
