Try to compile with -nobuiltininc. The problem is that some MSVC
include have the same name as the clang builtin headers. When
compiling MSVC code you really want clang to pick the MSVC one.

FYI here is the clang options command I use to test clang against MSVC code:
In the absence of a clang CL.EXE compatible driver this set of option
kind of emulate cl.exe


clang -cc1 -fcxx-exceptions -fdelayed-template-parsing -fms-extensions
