--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed. The warnings should be easy enough to suppress in the attribute
copy handler. Attribute weakref on extern symbols has been rejected since
r108074 (GCC 4.1 seems fine with it). I have no idea it would take to accept
them with the correct semantics.
