Can 4.9.1 be successfully built with unity builds turned off?

I am having some issues building UE4 4.9.1 when I disable unity builds. There are several compiler errors that prevent the Editor / Game from building. Is 4.9.1 for sure building when unity builds are disabled? Anyone else trying to do this? Some trick to prevent build issues when using non-unity builds?

Hello? Surely someone has an answer to this! I should mention I’m building Win64, 4.9.1 via msbuild (Visual Studio 2013), DevelopmentEditor configuration.
