[boost] [multiprecision][build] Massive unexplained failures in develop

Can anyone help me understand why just about every multiprecision test 
on every platform is failing with link errors, for example: 
http://www.boost.org/development/tests/develop/developer/output/teeks99-09d-win2012R2-64on64-boost-bin-v2-libs-multiprecision-test-test_arithmetic_ab_1-test-msvc-11-0-dbg-adrs-mdl-64-dbg-symbl-off-lnk-sttc-rntm-lnk-sttc.html

Note that it's complaining about a missing *object* file:  I've checked, 
and the necessary source files are present in the repository, plus I've 
pulled those changes on to a virtual machine and everything builds fine 
locally.  So there's something odd about the build when run from /status 
or what exactly?

I'm hoping someone can spot something obvious here, or else the testers 
can tell me where the object file actually placed?

Thanks, John.
