Windows Issue: gopherjs test ... does fail under Windows

[rusco]

Probably related to #341 :

//file dummy_test.go:

package dummy

import "testing"

func TestNothing(t *testing.T) {
}

go test ...pathtodummypackage

gives: ok

gopherjs test ......pathtodummypackage

gives: FAIL

without any further info. (Win7, 64/Node 4.2.1+sourcemap). There are no syscalls involved while testing, right ?
