But maybe this combination at least also detects > the use of newer (C23) extensions? We shouldn't be the only project hit by the unconditional use of _Generic in glibc 2.43 headers, should we? I was hoping that this would be fixed upstream, and that anything we do locally is merely a workaround of a tentative nature. > In any case, I'm also happy with the patch you posted. Thanks! Thanks for a quick response. You may have guessed correctly that I want to fast-track this topic down to 'next' and 'master' soonish to salvage CI jobs running for them.
