issues with native plugin in directX 11

I was having issues with shadows in DirectX 11 and the Native Plugin example on DirectX 11.
http://docs.unity3d.com/Documentation/Manual/NativePluginInterface.html

Both the native plugin and shadows worked when I disabled DirectX 9 or ran in -force-opengl mode.

I modified RenderingPlugin.cpp when it assigns the compiler dll, and then the Native Plugin Interface worked in DX11. I added a loadlibrary for D3DCompiler_47.dll in addition to D3DCompiler_46.dll:

if (compiler == NULL)
{
// Try compiler from Windows 8 SDK
compiler = LoadLibraryA("D3DCompiler_47.dll");
}

Of course it didn't effect shadows. Looks like other people have issues with that too.

My setup is a Toshiba Qosmio with Intel graphics and NVidia 770M
