--- Comment #2 from Eric Gallager <egallager at gcc dot gnu.org> ---
Confirmed, output now looks like this now that there's underlining and stuff:

$ /usr/local/bin/g++ -c -Wall -S 43454.cc
43454.cc:7:44: warning: ‘check_moo’ defined but not used [-Wunused-variable]
 static int (* __attribute__ ((__unused__)) check_moo) (void) = gnulib::moo;
                                            ^~~~~~~~~
