	* include/tr1/functional (_Maybe_wrap_member_pointer): Wrap up
	member pointers in _Mem_fn but let other function objects pass
	through unchanged.
	* include/tr1/functional_iterator (bind): Reduce number of bind()
	overloads to two to eliminate ambiguities. Use
	_Maybe_wrap_member_pointer to handle member pointers gracefully.
