Oy, what a sea of ifdefs. I think it's time for aurawin, aurax11 and chromeos

Done. Fluctuated a lot with the various permutations - see what you think of
what I came up with.

+#include "chrome/browser/ui/views/frame/browser_frame_ash_win.h"
+#endif
+
 NativeBrowserFrame* NativeBrowserFrameFactory::Create(
     BrowserFrame* browser_frame,
     BrowserView* browser_view) {
 #if defined(OS_CHROMEOS)
   return new BrowserFrameAsh(browser_frame, browser_view);
 #else
 #if defined(USE_ASH)
   if (chrome::ShouldOpenAshOnStartup() ||
       browser_view->browser()->
           host_desktop_type() == chrome::HOST_DESKTOP_TYPE_ASH) {
+#if defined(OS_WIN)
+    return new BrowserFrameAshWin(browser_frame, browser_view);
+#else
     return new BrowserFrameAsh(browser_frame, browser_view);
+#endif
   }
 #endif  // USE_ASH
   return new DesktopBrowserFrameAura(browser_frame, browser_view);
 #endif
