I believe that clang using VC++ RTL needs to be compatible with vc12,
not vc10. The reason for this is that clang defines _MSC_VER to 1700,
which is the correct number for vc12. Will setting the compatibility
flag as <compatibility>vc12 work correctly with your patches ?
I was also told that the compiler options "-D_HAS_EXCEPTIONS=0 /GR-"
should be set. You may be doing this automatically, but I have set it in
my user-config.jam as <cxxflags>"-D_HAS_EXCEPTIONS=0 /GR-".
