Instead of using a fixed header size, it depends upon packing of each struct, so the only truly reliable way to get the data is declare a struct. Without the macro the first case becomes:

`    case D3D12_PIPELINE_STATE_SUBOBJECT_TYPE_ROOT_SIGNATURE:`  
`    {`  
`        struct`  
`        {`  
`            D3D12_PIPELINE_STATE_SUBOBJECT_TYPE type;`  
`            ID3D12RootSignature *root_signature;`  
`        } *subobject = (void *)stream_ptr;`  
`        desc->root_signature = subobject->root_signature;`  
`        break;`  
`    }`

It can be done that way if you prefer.
