Isn't the correct fix usually to change _MSC_VER to BOOST_MSVC?

Other than for the config library, I would really like to ban _MSC_VER 
(unless accompanied by a comment that says "// including non-Microsoft 
compilers". Otherwise, when you see _MSC_VER in source code, you never know 
if the author remembered that compilers other than VC++ define it, and 
often with unhelpful values.

Is this something we want to try to fix this release? There is possibly 
suspect _MSC_VER use in the Boost headers listed below.
