AppVeyor fails the compilation (ERROR @ Slack Bee)

[LorenzoAncora]

I see legitimate commits automatically marked as invalid by AppVeyor.

Exception:

It would be appropriate to solve the problem: people have no reason to send code knowing that it will be marked as invalid irrespective of its actual correctness (especially if they do not want to have anything to do with Slack).

Fixed in master.
