3534	[signals2] compile error with MSVC 2010 Beta 2	Richard Webb <richard.webb@…>	Frank Mori Hess	"When trying to build a project that uses Signals2 in VC2010 beta 2, i got the error:

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."	Bugs	closed	Boost 1.42.0	signals2	Boost 1.40.0	Problem	fixed
