ENOTDIR = 27 on windows

stats.js line 16:

ENOTDIR = 20;

On windows, watchTree does not work as the errno of ENOTDIR is 27 not 20.

Same goes for ENOENT, which is not 2 but 34 on windows.

In first semester programming exam I got points removed for handling control flow with exceptions. It seems that is what you are doing here. Maybe you can find a better solution?

Still really happy that I finally found a tree watcher working on windows!
