This matches the #if that surrounds GetLinuxWindowManager().

Do you want to break this up into two #if blocks?

+#if defined(OS_LINUX) && !defined(OS_CHROMEOS)
   UMA_HISTOGRAM_ENUMERATION("Linux.WindowManager",
                             GetLinuxWindowManager(),
                             UMA_LINUX_WINDOW_MANAGER_COUNT);
