Node 4.1 support

[alanhogan]

It looks like this is incompatible with node 4.1.0 at this time.

This isn’t of concern to me at this time, but thought there should probably be an issue to discuss / track support.

(Seems like a lot of folks are having node-gyp problems in node 4.1. My current approach is sitting tight on 0.12 for the time being. Gotta say, the current major version of node jumping from 0 to 4 nearly overnight has confused a lot of people around me)

I bumped into this recently :( will dig in for next release.

See nodejs/node#2798

Workaround is to use g++ >= 4.8

[alanhogan]

Super long discussion there! I see only passing reference to g++ in it. Is eyeglass-spriting confirmed to work in node 4.x and newer?

[eoneill]

Yep, confirmed eyeglass-spriting works in node 4+. I'm using it locally with node 5 and all tests are passing in travis now in 4+.

This was the change needed to get it passing in travis: eoneill@f2fc3ad

Ah, thanks. That will be helpful.
