Sorry I'm so late again.  It doesn't crash, but it does cause an error:

xemacs-21.4 src/xemacs -vanilla -batch -eval '(mswindows-send-sys-command #xf030)'
Wrong type argument: console-mswindows-p, #<stream-frame "stream" 0x12c>
xemacs exiting

Same when used in tty.  This can be avoided using a frame_type_p test:

  if (NILP (frame)) 
    frame = Fselected_frame (Qnil);
  if (FRAME_TYPE_P (XFRAME (frame), mswindows))
  {
      CHECK_LIVE_FRAME (frame);
      CHECK_INT (command);

      PostMessage (FRAME_MSWINDOWS_HANDLE (XFRAME (frame)), WM_SYSCOMMAND,
                   XINT (command), 0);
  }

  return Qnil;

Seems to work fine for native windows frames, X11 frames, tty and batch.
