Why are you removing these entries?

[Slava Chigrin, 2014/12/16 13:32:34]

This is a part of  "deps -=" list, so removing is in fact enabling targets.
As far as I understand, these targets are disabled temporerily in
https://codereview.chromium.org/709593004 , until all GN targets will not be
fixed.

[tfarina, 2014/12/16 13:42:46]

OK, I see. With this you are enabling those targets on Windows. As you made sure
they build there. Is that right?

Yes, and try jobs are completed successfully too.
