I would recommend this as the point to us #ifndef in the same manner as is done
for BackgroundModeManager::GetPreferencesMenuLabel

 void BackgroundModeManager::EnableLaunchOnStartup(bool should_launch) {
   // This functionality is only defined for default profile, currently.
   if (CommandLine::ForCurrentProcess()->HasSwitch(switches::kUserDataDir))
     return;
   if (should_launch) {
     BrowserThread::PostTask(BrowserThread::FILE, FROM_HERE,
                             new EnableLaunchOnStartupTask());
   } else {
     BrowserThread::PostTask(BrowserThread::FILE, FROM_HERE,
                             new DisableLaunchOnStartupTask());
