Although I think that's better than nothing, it doesn't help people
who upgrade from, for example, 1.54 to 1.56 and skip the 1.55 version
with the warning. In my experience many users only upgrade Boost
occasionally, rather than at every release.

To help those people later versions could replace the "This is the
last time that this will work!" message that can be disabled via a
macro with a message that can't be disabled saying "Boost 1.xx is the
last version that supports your compiler"
