Thanks for implementing this!

I filed a follow up wrt to how this diagnostic interacts with `register`
storage variables.

--- Comment #2 from Eric Gallager  ---
Now that -fno-common is the default, having this flag would make it easier to
catch mis-declared variables that will turn into link errors at link time by
catching them at compile time instead, so I'd think it's a bit more important
now.
