Description
The test in boost/tr1/detail/config.hpp indicates native TR1 support only if the _HAS_TR1 macro is set and non-zero. This was set by VC2010, but 2012 no longer defines this symbol. Consequently, Boost's implementation is used and conflicts ensue.
_HAS_TR1 is a private symbol that shouldn't be checked according to this:

Attached patch fixes this by also checking for VC11+ via _MSC_VER.
