No, I didn't. Should we address the following concern (maybe only for `c23`) by

The whole point of attribute-prefixs is to be able to use attributes for 
multiple compilers without a #ifdef-hell. Thus, there is no reason for this 
warning to be raised. And if a warning has to be raised, it should be a 
different one (perhaps -Wunknown-attribute-prefix) such that it can selectively 
be disabled (since -Wunknown-attributes is useful in case of misspelled 
attributes in general).
