Actually, there is one more actual code change here - libc++ wouldn't let me
assign a default value here.

[sergei, 2015/01/06 13:51:39]

Actually, when do we need a default value here?

Regarding the code, it's surprising that it was working with ` = 0`. Have you
tried ` = UpdaterCallback()`?

[Felix Dahlke, 2015/08/04 11:21:49]

Probably some subtle differences between std::function and std::tr1::function?
Also not entirely sure if this would have worked, we're not using it anywhere.
Let's just get rid of the default until we have a use case for it, I'd say.
