No, it's just COM calls. I just changed the old mingw-specific calls
to the proper Windows API entries. It builds fine here with mingw
without d3d10.lib/a at all.

Strangely the Win8/8.1 and 10 SDKs don't ship with D3DX9Mesh.h or
D3DX9Shader.h. You need to install an older SDK to have them. d3d9.h
is still there.

But I agree, that may cause problems because we look for
"D3DXCompileShader" from the d3dx9* DLL (whichever variant is found
first). Rather than "D3D10CompileShader" from a more recent DLL.

So we should just keep the code as is for now. Maybe supporting both
in the future.
