I don't think this is a gcc issue. It's a reasonable point of view, 
right, but pushing the header file issue back to libunwind is a valid 
POV, too. I think it's rather a problem between those two packages.

Did you give this a try? I'll check it as soon as I can.

I took word from Steffen (Sledz) about the cause of the problem, so I 
didn't investigate any further. Introducing the dependency seemed to fix 
the problem, so why bother. However, I feel like this kind of problem is 
better fixed (the way you're proposing it) by the package maintainer, if 
there is one.
