Specifying a kDriver_Name results in error during compilation.

Reproduction Steps

Open XCode - change signature to ad-hoc.
export GCC_PREPROCESSOR_DEFINITIONS="kDriver_Name=Dolby5.1 kNumber_Of_Channels=6 kLatency_Frame_Size=0" *Also tried other names and setting kDevice_Name to the same thing.
xcodebuild -project BlackHole.xcodeproj GCC_PREPROCESSOR_DEFINITIONS=$GCC_PREPROCESSOR_DEFINITIONS or xcodebuild -project BlackHole.xcodeproj GCC_PREPROCESSOR_DEFINITIONS=$GCC_PREPROCESSOR_DEFINITIONS -configuration Release
