+ * In C23 alignas and alignof are keywords, so this header defines only the
+ * feature-test macros __alignas_is_defined and __alignof_is_defined. In C17
+ * (and older) it additionally maps them onto the _Alignas/_Alignof keywords.
+ * In C++ the two names are keywords as well.
+ *
+ * This header is ISO C core and is present in every profile.
