[cfe-dev] Stop Clang from including problem headers from visual studio 11

Thu May 9 08:27:10 PDT 2013

Whoops, looks like even if you unset %INCLUDE% clang still falls back
to heuristics to find MSVC's headers.

Looking at the code in clang/lib/Driver/WindowsToolChain.cpp shows you
can pass -nostdinc to turn this all off.
