Hi,

Based on recent news:
Clang 6.0.0 is out with very decent support of the latest MSVC STL (15.6).
Chrome is built with clang on Windows.

So, maybe it is good time to include clang+windows into list of
supported configs, setup a CI worker with clang (clang-cl) on Windows?
Currently many boost libs already work fine, but some of them require
small tweaks like explicit BOOST_USE_WINDOWS_H etc.
