Thanks, Eli. That's worked like a charm. But no good deed goes
unpunished, so here's my next question.

I need to be able to handle cases where the "extern" appears on a
forward declaration, like this:

extern const int x4;
const __declspec(selectany) int x4=4;

If I check the storage class in Sema::ProcessDeclAttributeList, it
doesn't show up as extern in this case. I need to check the storage
class somewhere else. Any ideas where?
