Hi,
When I install cordova-plugin-mixpanel in my Ionic 2 solution and kick off a package/build on Ionic cloud for iOS it fails witht his error:

char colorIndices[kNumberOfHexColors] = {0};
It seems it can be fixed by setting the “C language dialect” to default as described here: https://github.com/samzilverberg/cordova-mixpanel-plugin/issues/52
