--- Comment #7 from uecker at gcc dot gnu.org ---
This is a C FE bug because the update logic for c_update_type_canonical uses
check_qualified_type that - for some reason - decides that certain types are
not qualified versions of the original. This seems related to TYPE_DECLS. The
new verification code in the FE also detects these problems in similar
examples.
