Pretty sure that's covered. Check the manual for your version of gcc.
Here's what the 3.3.1 manual has to saw:

  
http://gcc.gnu.org/onlinedocs/gcc-3.3.1/gcc/Warning-Options.html#Warning%20Options

If we want to enable more than what -Wall gives, the infrastructure is
in place now and it should be trivial.

I'll add a hook to allow -Werror only if an env var is set. Then the
default will be without, but those that want it (like myself) can
enable it manually. I'll probably make the env var such that you can
use it to add any extra CFLAGS to avrdude_CFLAGS. Then it will be
possible to tweak the CFLAGS without having to reconfigure.
