Windows not recognized properly

[UlrichAlt]

Look at this example in node_shims/path.dart

_PathExports _factory(){
var exports = new _PathExports();

var isWindows = Platform.operatingSystem == 'win32';

if (isWindows) {
// Regex to split a windows path into three parts: [*, device, slash,
// tail] windows-only

However, Platform.operatingSystem returns "windows" in my case instead of win32 which makes the whole thing believe to run on linux and therefore fails the whole build system for templates.
