You don't need uninitialized_var bloat anymroe, right?

I guess I don't fully understand the 'unitialized_var()' macro, and was
just following the previous uses in the code.

Google'ing doesn't really help either. Is there a definitive guide as when
to use and not?

As Jiri Slaby already explained, it's rather a hack to shut up gcc in 
cases in which it gets the unused warning wrong.

But even that is considered controversial by some people ...
