--- Comment #1 from David Blaikie <dblaikie at gmail.com> ---
Warning args are ordered, -Wno-* args must appear after the positive -W that
enabled the warning (in your example, I believe -Wall is enabling the warning
so -Wno-format-extra-args must appear after -Wall)
$ clang++ arg.cpp -Wall -fsyntax-only
arg.cpp:4:15: warning: data argument not used by format string
[-Wformat-extra-args]
  printf("x", "y");
         ~~~  ^
1 warning generated.
$ clang++ arg.cpp -Wall -fsyntax-only -Wno-format-extra-args
