nice ; including the expand_loc for INT1 and any attributes attached  
to the decl.

use ; I'm working on __attribute__((deprecated)) issues ...

(at the moment the diagnostic for x does not include the declaration  
location).

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43797
and the earlier thread on patches.
http://gcc.gnu.org/ml/gcc-patches/2010-04/msg01037.html
and a followup:
