True.  Which leads to the question of what we want #pragma weak to mean for
really overloaded functions.  I suppose the alternatives are either to make
all currently declared overloads weak or give an error.  I lean towards the
latter.  Which suggests that handle_pragma_weak could just give an error if
the lookup finds something that is not a decl.
