Comment (by kencu):

 Funny, though -- I think this function should still be compileable and
 linkable if the function is declared weak. ie, because it is declared
 weak, the link should not be failing above.

 I'll have to read a bit more sometime about why this is not working here.

 For now, avoiding the function is the more obvious thing to do, at least
 until you (or I) can sort out why the weak function reference is failing
 to link...
