I think it should definitely be encoded in DWARF2.  (I don't know where; 
I just think it's a mistake for the debugger to be trying to figure this 
out for itself.  The rules are pretty subtle, and may be different from 
architecture to architecture, or compiler release to compiler release, 
even, if we make an intentional change.)

For stabs, you're probably hosed -- but then again, aren't you just 
generally hosed with stabs? :-)

Yes.
