--- Comment #5 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > It seems that Mac OS doesn't have the full set of C11 standard headers... :-( Shouldn't the C11 standard headers be provide by GCC12? Nevertheless the test compiles with the new version of the new C companion. The same is true for 100910 and 100914.
