--- Comment #1 from Iain Sandoe <iains at gcc dot gnu.org> 2010-12-13 09:23:54 UTC ---
this also appears on i686-darwin9.

the weak symbol errors appear with:
http://gcc.gnu.org/ml/gcc-cvs/2010-11/msg00974.html

I guess, if a symbol is artificially weakened - then one must recall
section_for_xxxxx() because, at least on Darwin, weak symbols can only appear
in [linker] coalesce-able sections.

Honza?
