there's issues in general with trying to force visibility onto everything ... 
sometimes it's the package, sometimes it's gcc generating code incorrectly, 
etc...

i'm purposefully being vague because i dont have the exact details at my 
finger tips atm

it isnt really suited to be an autoconf test as if we start trying to "handle" 
everything experimental gcc flag, we're going to be wasting a lot of time ...
