Microsoft recommends against using .user files. From
https://msdn.microsoft.com/en-us/library/669zx6zc.aspx :
"The best practice is to delete the reference to them in Property
Manager to ensure that your projects operate independently of any
per-user, per-computer settings. This is important to ensure correct
behaviour in a SCC (source code control) environment."
If you cannot compile SPU2-X after this commit (since that still relies
on the old DirectX SDK), you'll need to fix your build environment.
