Yup.  I'm not familiar with DWARF-1, so conceivably it's possible
that we want to support C++ DWARF-1 debugging but that DWARF-1 is by
nature incapable of supporting the full range of C++ features, in
which case we'd only skip certain C++ tests under DWARF-1.  But I'm
really not worried about that possibility for now.

Anyways, my kneejerk reaction is that no, we shouldn't support it: I
have a hard time imagining a scenario where it would be a profitable
use of resources to work on supporting DWARF-1.  What platforms use it
as their native debugging format?  What C++ compilers run on those
platforms?
