Be afraid. Be very afraid.

On a more serious note; The first warning can be safely ignored. It
just means GCC can't use one certain type of optimization when it's
handling the variable in question (it's an effective one, so we'll
want to fix that eventually, but it's nothing major).

The second one could be a bit more serious but really isn't, since
we never use the imported object state anyway.

So in short; No, they're nothing to worry about.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
