I had the same problem on a project I was working on.  Here is how I solved
it.
  1) In the WM_CREATE for the FrameWindow create the MDIClient window with
     sizes of 0,0,0,0 (x,y,nx,ny).
  2) After the MDIClient has been created, create the StatusLine window as
     a child of the FrameWindow with sizes of 0,0,0,0.
  3) In the WM_SIZE message for the FrameWindow, do the following

         RECT rc;
         GetClientRect(hFrameWindow, &rc);
         MoveWindow(hStatusLine, 0, rc.bottom - nStatusLineHeight,
                      rc.right, nStatusLineHeight, TRUE);
         MoveWindow(hMDIClient, 0, 0,
                      rc.right, rc.bottom - nStatusLineHeight, TRUE);

What this will do is create a MDIClient window that is smaller than the Frame
client space.  Hope this helps...
