Is __INCLUDE_LEVEL__ supported by most compilers?

So it's a gcc extension that's been around for quite a while. This repo seems to imply that it is supported by most compilers. If so, that would be really cool, as it would simplify the process of creating new libraries. Anyone know if that really is the case here?

I would say, no. They are predefined in Gnu compilers but may not be in every compiler. The C18 C Standard does not even mention this.

You should not rely on this in portable code, or preferably in ANY source code.

Right. Not without a "requires gcc" kind of disclaimer anyway. Ok. Well that's pretty much what I expected to hear. Thanks!
