 The configuration file

 boost/config/compiler/visualc.hpp

 incorrectly enables support for pragma detect_mismatch for Visual Studio
 2008 as of the lines 107-109:

 {{{
 #if _MSC_VER >= 1500  // 150X == VC++ 9.0
 #  define BOOST_HAS_PRAGMA_DETECT_MISMATCH
 #endif
 }}}

 This has the effect that compliation against MSVC++ 9.0 leads to a series
 of warnings such as:

 {{{
 boost/type_index.hpp(37) : warning C4068: unknown pragma
 }}}

 According to my experience - and covered by the information provided here
 [The following should be interpreted as an URL]:

 http
 boost.2283326.n4.nabble.com
 Boost-and-Microsoft-s-SECURE-SCL-td3025203.html

 the new pragma exists since Visual Studio 2010 (_MSC_VER == 1600)
