If this header only defines the contents below for Mac and Win, how are test
files that reference these without a guard ifdef going to compile on Linux? 
Even if we disable the tests, that's a runtime thing, not a compile-time one, I
believe.

Right, it won't work for tests which are disabled with DISABLED_ prefix. I added
dummy implementation for other platforms.
