Personally, I like my stuff to be warning free, and in something as
"core" as type_traits, any warning at all can be a real pain that gets
repeated dozens of times each with 10 pages of instantiation back-trace,
so I think it makes sense to enforce a no-warnings policy in that one
case. In other libraries, and in particular if they have dependencies
on other Boost libraries (even just testing dependencies) then trying to
enforce a no-warning policy is probably a road to perdition.
