I did not toggle the defect macros for those features as my goal was to
get it into a buildable state as-good-as-predecessor before twiddling
the knobs for the new capabilities.

My own code seems to still build with the small variety of libraries it
includes if I change the condition [1] to not define the defect macros, but
that's not really an exhaustive test.

[1] #if _MSC_FULL_VER < 170051025 || _MSC_FULL_VER < 180020617 && !defined(BOOST_MSVC_ENABLE_2012_NOV_CTP)

Try it and see, I guess. I'd reckon that they will probably cause little
harm, considering that there's people who have tested the Nov12 CTP in
the past.

Speculative definition of features of a non-existing compiler based on
promises is a bit too bold, even for my taste.
