As reported earlier, Boost.Optional's new boost::none leads to compile 
errors when using precompiled headers. Defining 
BOOST_OPTIONAL_USE_OLD_DEFINITION_OF_NONE works around the problem, but 
that should probably be mentioned somewhere in big red letters as the error 
message on MSVC is a bit cryptic ("' ?? A0x06d21c56': 
the symbol to the left of a '::' must be a 
type"). I haven't found BOOST_OPTIONAL_USE_OLD_DEFINITION_OF_NONE 
documented anywhere.

Apart from that, everything seems to work fine on MSVC12.
