Thanks for reporting the problem. I think the problem is in the 
HAS_INCLUDE macro, which now that I look at it more closely doesn't 
conform to C23 either. Although I doubt whether the problem is the 
true/false stuff I'll move those macros earlier just in case; that's 
more robust anyway.

Please try the attached patch, which I installed into the development 
repository on GitHub.
