In get_pointer.hpp, switched to using <boost/config/no_tr1/memory.hpp> instead of using <memory> directly. As above, this helps avoid circular header dependency issues in Boost-supplemented std libs (specifically it avoids issues when <memory> pulls in pieces of Boost.SmartPtr). These two changes were made in response to testing done with STLport 5.2.1 using the _STLP_USE_BOOST_SUPPORT option. [SVN r52221]
