Subject: [PATCH] [multiple changes]

2005-11-13  Jonathan Wakely  <redi@gcc.gnu.org>

	* include/tr1/boost_shared_ptr.h (get_deleter):
	Declare before shared_ptr.
	(shared_ptr<>): Declare get_deleter as friend.
	(shared_ptr<>:_M_get_deleter): Private.

2005-11-13  Douglas Gregor  <doug.gregor@gmail.com>

	PR libstdc++/24818
        * include/tr1/ref_wrap_iterate.h
        (reference_wrapper::operator()()): Don't dereferene the result of
        get() before calling it; it's already a reference.
        * testsuite/tr1/3_function_objects/reference_wrapper/invoke.cc:
        Test nullary calls to reference_wrappers.
