 When trying to build a project that uses Signals2 in VC2010 beta 2, i got
 the error:

 {{{
 boost/signals2/detail/tracked_objects_visitor.hpp(61): error C2668:
 'boost::addressof' : ambiguous call to overloaded function
           \boost/utility/addressof.hpp(51): could be 'T
 *boost::addressof<const T>(T &)'
           with
           [
               T=lapi::ui::type_1::fn_label_change
           ]

 &)' [found using argument-dependent lookup]
           with
 }}}

 Seems that it's finding std::addressof via ADL if the type passed to
 addressof is from namespace std;.

 Changing line 61 of tracked_objects_visitor.hpp to use boost::addressof
 explicitly allows it to compile.
