incomplete rtti

[Jim Dehnert]

I'll try to make this clearer.  However, the sentence you complain about
is correct:

> 	After linking and loading, only one type_info structure is accessible
> 	via the external name defined by this ABI for any particular complete
> 	type symbol.

It does NOT say that no other type_info structures are accessible, only
that there's only one with the ABI-defined name.  This is true for all
types, including pointers.  Your problem is that some "complete"
pointers may reference other type_info structures.  Anyway, I've fixed
this paragraph and the next one you mention -- see what you think.

I think the reason you can't just check the NTBS of the pointer is
precisely because of intervening CV-qualifiers.  Or do they always have
to match?  Anyway, I haven't changed this paragraph, pending better
understanding.
