// In Node these values are coming from libuv:

// Since there is no easy way to port code from libuv and these maps are
// changing very rarely, we simply extract them from Node and store here.

// Note
// Run the following to get the map:
// $ node -e "console.log(process.binding('uv').getErrorMap())"
// This setup automatically exports maps from both "win", "linux" & darwin:
