I remain still confused as to what controls the choice of clang-linux and clang-win, and what needs to switched.

If you just need to test things using "b2 test toolset=clang", I repeat my recommendation of using Cygwin. It has g++ 6.3 and clang 3.9, and they work more or less "out of the box". The only thing I did was symlink clang-3.9.exe to clang++.exe.
