I think I might have said something stupid here. We were trying to use VS2013 because it seems to be the first VS to support "Universal Phone / Store Apps" which means I need to get these builds working using toolset=msvc-12.0 or I will have to go back to VS2012. 

Have you been able to build using msvc-12.0?

So for now, I think I can just work around the problem using the other toolset.
