This affects VC10 mainly. It has the features it has, and no way of
turning them on or off.

I guess this means that macros BOOST_NO_xxx will not be defined.

Wouldn't that be a library specific switch 'don't use even if
available'? If the feature is available, and working properly, why not
use it?
