The problem is you'd need to either place the pragmas around all the usages 
of BOOST_STD_EXTENSION_NAMESPACE::hash_xxx with VC guards, e.g.:

#if defined(BOOST_MSVC)
#     pragma warning( push )
#     pragma warning( disable : ... ) // remove deprecated warning
#endif

   // use BOOST_STD_EXTENSION_NAMESPACE::hash_xxx here

#if defined(BOOST_MSVC)
#     pragma warning( pop )
#endif

This is, IMHO, an ugly solution. The other option requires adding the 
disable warning on the command-line which is not good since it requires 
altering makefiles or project settings and is thus not portable.

Reece
