 Some recent version of Microsoft Visual C++ Compiler still has only 8
 digits for _MSC_FULL_VER. In this case, intrinsics compiler are not
 activated and some traits (like is_pod) are broken.

 To fix it, I suggest to introduce the macro BOOST_MSVC_FULL. Its value is
 normalized. The code is inspired from http://www.crystalclearsoftware.com

 /cgi-bin/boost_wiki/wiki.pl?BoostConfig (search for _MSC_FULL_VER)

 The patch include change for all librairies, but I tested it only on
 type_traits library. If such patch is not possible, I would suggest to, at
 least, fix the way intrinsics are activated on Visual C++.

 Thanks
