Re: [boost] Boost and clang under Windows

The Boost header files have numerous places where testing the macro _MSC_VER produces slightly different behavior based on the fact that the code is being used by VC++ or a compiler with the same behavior as VC++. But clang does not have the same behavior as VC++ despite defining _MSC_VER.

That shouldn't really be happening - the code should check for BOOST_MSVC if it really want's "real" msvc and _MSC_VER just for things like #pragma once where some simple form of msvc emulation is required. John.
