Ok - it's a feature ;-)

But given the rate of Visual Studio updates (roughly every Msec ;-) roughly the same as time for the Boost release process to
complete), so the odds are that Boost will never catch up Visual Studio!).

So I'm not entirely convinced that this will prove terribly helpful.

It might be intuitive to say

  Info: Your compiler version is newer than Boost.Config.

Would a shorter message and a link to a fuller explanation like

  Info: Boost.Config is older than your compiler version.
  (See also http://boost.org/link_about_this_message.)

be less clutter and not cause user 'alarm'?
