public class Hack
{
  [Conditional (condition=G_OS_WIN32)]
  [CCode (cheader_filename = "gdk/gdkwin32.h", cname = "GDK_WINDOW_HWND")]
  public static uint32 get_handle (Gdk.Drawable drawable);

  [Conditional (condition=G_OS_UNIX)]
  [CCode (cheader_filename = "gdk/gdkx.h", cname = "GDK_WINDOW_XWINDOW")]
  public static uint32 get_handle (Gdk.Drawable drawable);
}

And compilation with -DG_OS_UNIX or -DG_OS_WIN32.
