generated import statements have '/' in name, causing failures

Downloaded the example code and tried running the update-codegen.sh (no was code modified):

Looking at the generated code- the imports are being created as follows:

import (
github_com/golang/glog "github.com/golang/glog"
k8s_io/client_go/discovery "k8s.io/client-go/discovery"
k8s_io/client_go/rest "k8s.io/client-go/rest"
k8s_io/client_go/util/flowcontrol "k8s.io/client-go/util/flowcontrol"
example.comv1 "github.com\openshift-evangelists\crd-code-generation\pkg\client\clientset\versioned\typed\example.com\v1"
)

Using go 1.9.1 on cygwin (Windows). Any ideas?

import (
github_com/golang/glog "github.com/golang/glog"
k8s_io/client_go/discovery "k8s.io/client-go/discovery"
k8s_io/client_go/rest "k8s.io/client-go/rest"
k8s_io/client_go/util/flowcontrol "k8s.io/client-go/util/flowcontrol"
example.comv1 "github.com\openshift-evangelists\crd-code-generation\pkg\client\clientset\versioned\typed\example.com\v1"
)

The generated imports look wrong.

/cc @sttts maybe a windows thing/error which generates it this way?

For me (Fedora):

➜  crd-code-generation git:(master) ./hack/update-codegen.sh 
Generating deepcopy funcs
Generating clientset for example.com:v1 at github.com/openshift-evangelists/crd-code-generation/pkg/client/clientset
Generating listers for example.com:v1 at github.com/openshift-evangelists/crd-code-generation/pkg/client/listers
Generating informers for example.com:v1 at github.com/openshift-evangelists/crd-code-generation/pkg/client/informers

And imports:

import (
	glog "github.com/golang/glog"
	examplev1 "github.com/openshift-evangelists/crd-code-generation/pkg/client/clientset/versioned/typed/example/v1"
	discovery "k8s.io/client-go/discovery"
	rest "k8s.io/client-go/rest"
	flowcontrol "k8s.io/client-go/util/flowcontrol"
)

I guess the generators were never tested on Windows. PRs fixing this are very welcome.
