If I invoke 'b2 toolset=clang-win-7.0' against some test jam file with a 
user-config.jam file of 'using clang-win : 7.0 : 
C:/Utilities/LLVM/700/x32/bin/clang-cl ;' everything works fine. But if 
I invoke 'b2 toolset=clang-win-6.0' against some test jam file with a 
user-config.jam file of 'using clang-win : 6.0 : 
C:/Utilities/LLVM/601/x32/bin/clang-cl ;' I constantly get:

C:\Program Files (x86)\Microsoft Visual 
Studio\2017\Community\VC\Tools\MSVC\14.16.27023\include\yvals_core.h(294,5): 
  error: STL1000: Unexpected compiler version, expected Clang 7 or newer.
    #error STL1000: Unexpected compiler version, expected Clang 7 or newer.

Even if I add a 'using msvc : 14.0 ;' to my user-config.jam the same 
problem occurs. It seems as if clang-win always uses the latest version 
of vc++, which of course does not work with an earlier version of clang, 
as the error message shows.
