OS_LINUX will return true for Chrome OS too, I believe - you may need to do
something like defined(OS_LINUX) && !defined(OS_CHROMEOS).

Or, since I believe OS_CHROMEOS is the only one left, you may be able to replace
this whole line with:

#if defined(OS_CHROMEOS)

Maybe try it? Run a full set of try jobs (git cl try from command line) to see
what fails.
