Comments in GCC’s included headers for <stdalign.h> and <stdbool.h> are updated to reflect that certain macros have been removed in C23 and C++26. While the macros themselves are not removed in this patch to avoid breaking existing code, the comments serve as a warning to developers about their obsolescence and potential removal in future standards.
