Getting -nostdinc to work with --driver-mode=cl

Hey all,

As soon as I enable --driver-mode=cl and -nostdinc at the same time and compile a C file, i’m greeted with the error:
clang.exe: error: unknown argument: ‘-nostdinc’

I’m using the windows release:

clang version 3.8.0 (branches/release_38)
Target: x86_64-pc-windows-msvc

It seems this is supposed to be supported, because MSVCToolChain.cpp in clang source uses this:

void MSVCToolChain::AddClangSystemIncludeArgs(…) {
if (DriverArgs.hasArg(options::OPT_nostdinc)) return;

}

How do I get clang-cl mode to accept -nostdinc?

Thanks,

Ivan
