I'm still seeing this behavior in 4.8.4.  #pragma can ignore
unused-local-typedefs, _Pragma cannot.  This is on Ubuntu 16.04.  Options are
-fPIE -O3 -NDEBUG -Wall -Wextra -Werror.  Because of -Werror, I also tried
putting in _Pragma ("GCC diagnostic warning \"-Wunused-local-typedefs\"")
before the ignored.  But regular #pragma works just fine.
