Hi,
I'm wondering if we care about level 4 MSVC warnings. As far as I remember 
default warning level is lower and I don't see why boost sources should have 
MSVC-specific pragmas just to disable level 4 warnings.

I'd rather resolved the bug as invalid. As an alternative, we could

// Beginning of file
#include <boost/config/warnings_off.hpp>
...
// end of file
#include <boost/config/warnings_on.hpp>

and have an option BOOST_CONFIG_TURN_WARNINGS_OFF.

Though, I don't know whether it's doable for other compilers.
