This version looks much nicer. I'm still confused about
die_needs_namespace, but I think we're almost done.

Recursing to follow the specification makes sense. I don't think
recursing onto the parent makes sense though. Won't this cause
the wrong answer for:
DW_TAG_subprogram
DW_TAG_variable
? If that doesn't matter, then I'm totally confused again :-)
That's your basic local variable.
Otherwise, everything looks OK.
