LLVM 4.0.0 Clang (using clang-linux toolset), -fno-ms-compatibility:

...failed updating 1 target...
...skipped 3 targets...
...updated 262 targets...

The failure is because you pass -std=c++0x, but MS's headers indirectly 
included by config_info use C++14 features. Should work with -std=c++14.

-fms-compatibility (using the strict config, as patched):

...failed updating 1 target...
...skipped 3 targets...
...updated 132 targets...

This one doesn't even fail seq.cpp, was probably a bug they fixed.

No idea why you couldn't get it to work, all I did was install LLVM in 
C:\LLVM and then added

using clang : 4.0 :
  "C:/LLVM/bin/clang.exe" :
  <compileflags>-fno-ms-compatibility ;

in user-config.jam. I probably don't even need the <compileflags>, it works 
either way.
