I don't think you need this -- I think you can just put it in the
chrome_browser_task_manager_sources list without any conditionals.

If a file in the main list has a platform suffix like _win.cc or _posix.cc, it's
supposed to be automatically excluded from other platforms. This is thanks to
the common rules in:
https://cs.chromium.org/chromium/src/build/filename_rules.gypi?q=_posix+file:...

That's neat! Will fix this.

[stanisc, 2016/08/01 22:34:27]

Done.
