I don't think this is used in this file, but seems to cause compile build errors
if I remove it. I think you should probably move this to the actually required

Removed and added to components/sync/engine_impl/directory_update_handler.cc
instead, thanks!

Where is this used? Remove?

[maxbogue, 2016/08/19 19:12:01]

Done.

This is also getting #included, definitely don't need to forward declare it.

[maxbogue, 2016/08/19 19:12:01]

Done.
