Hmm, any reasons we are not excluding building the entire thing on non-Windows?

[robertshield, 2015/09/21 04:16:22]

Not really. I could #ifdef / gyp magic the whole thing away, though this has
been written with bringing it to Mac in the near future in mind. 

Let me know if you'd prefer I exclude the whole thing.

[engedy, 2015/09/21 12:56:10]

If we have other platforms in mind then I think it's fine to keep it as it is.

Acknowledged.
