[cfe-dev] VS2015 Update 3 type_traits Header Issues

[Daniel Dilts via cfe-dev]

I am now building my tool against trunk.  I am seeing the following errors,
which I had a long time ago and I seem to remember that the tool had to
know about where the Clang build copied certain files.  Is there some other
project that needs to be built to make this work?  I have already set
clang-headers as a dependency.
