If you need to check for the availability of numeric_limits, that supposedly
means that you intend to use it; and there's already a working solution in
place, namely boost/limits.hpp. As it already does The Right Thing, there's
no need to ever check for BOOST_NO_LIMITS.

As I didn't write those notes, this is only my interpretation, of course.
