Visual Studio 2012 C++ compile error with Boost Signal2

I am using Visual Studio 2012 Ultimate with the following Boost Signals2 code: at https://github.com/cfobel/boost_signals2/blob/master/hello_world_0.cpp It generates the following error: 

c:\program files (x86)\microsoft visual studio 11.0\vc\include\xmemory(348): error C4996: 'std::_Uninitialized_copy0': Function call with parameters that may be unsafe - this call relies on the caller to check that the passed values are correct. To disable this warning, use -D_SCL_SECURE_NO_WARNINGS. See documentation on how to use Visual C++ 'Checked Iterators'
1>          c:\program files (x86)\microsoft visual studio 11.0\vc\include\xmemory(333) : see declaration of 'std::_Uninitialized_copy0'
1>          c:\libraries\boost_1_52_0\boost\signals2\detail\auto_buffer.hpp(192) : see reference to function template instantiation '_FwdIt std::uninitialized_copy<I,boost::variant<T0_,T1>*>(_InIt,_InIt,_FwdIt)' being compiled

Is this code not compatible for Visual Studio 2012 C++? Is it still safe to use? Lastly, how do I make the changes as suggested? Thanks

C4996 is a warning about using a function that has been marked deprecated. Since you're seeing it as an error, maybe you have the Treat Warning as Error (/WX) option enabled?

The way to disable this one is described in the error message itself. Add the _SCL_SECURE_NO_WARNINGS symbol to the project's preprocessor definitions.
