When the ABI was designed, the committee made a conscious decision not
to support any kind of dynamic linking that did not merge names.  I do
not think we should revisit this at this point.

Therefore, if that is what this bug concerns, the bug should simply
be closed with a note explaining the issue.  For bonus points, an
entry should be added to the FAQ.
