Humm.  This sounds like a difference in how "friend" handling works in VS
2005.  I'm leaning towards not having to support such an old compiler.  I
tried adding additional friend declarations to help resolve this but adding
"friend Coverage::Iter" before Coverage itself is fully defined doesn't seem
to work, so I'm out of ideas for a simple fix short of making the Iter's
public.  That's probably not a big deal, but diverts from the current design
of HarfBuzz.
