Just an FYI, for my own build, I reverted my changes back to Boost 1.55 and applied the patch for serialization to build in msvc-12.0.  That got me past my build problems.  Hopefully, that is all I need.

As for the latest build, bcp, etc., I'll keep testing the develop branch and post back here, when things are working again.  Do I/we need to file any issues to track this?  This thread is all I have so far.

Thanks for all of the work.  Hope we can resolve this soon.
