Of course not. This compiler is not MSVC6 and BOOST_MSVC is not defined for it. No MSVC workarounds are applied (unless by mistake).

To clarify, by "features" I mean MSVC-specific extensions, and not standard C++ features. The intrinsic _ReadWriteBarrier, for example, first appeared in MSVC 7.1. A compiler that defines _MSC_VER to 1300 is unlikely to support it, even if it supports the whole of C++98 or C++03.
