See the comment in c_parser_typeof_specifier:

      /* For use in macros such as those in <stdatomic.h>, remove
         _Atomic and const qualifiers from atomic types.  (Possibly
         all qualifiers should be removed; const can be an issue for
         more macros using typeof than just the <stdatomic.h>
         ones.)  */

(If changing this, remember to change the __auto_type handling as well.)
