18/* The noreturn macro is deprecated in C23. We do not mark it as such because
19 including the header file in C23 is also deprecated and we do not want to
20 issue a confusing diagnostic for code which includes <stdnoreturn.h>
21 followed by code that writes [[noreturn]]. The issue with such code is not
22 with the attribute, or the use of 'noreturn', but the inclusion of the
23 header. */
