It seems to me that the problem is that lookup_and_check_tag is rejecting a
USING_DECL rather than returning it.  What if we return the USING_DECL?

If the USING_DECL is returned, the code below will be rejected as
expected, but the error message will not mention the line where the
USING_DECL appears as the previous definition, but at the target
declaration of the USING_DECL instead.

I think that's what happens if you strip the USING_DECL and return what it points to; if you return the USING_DECL itself that shouldn't happen (though then the caller needs to be able to deal with getting a USING_DECL).
