alg4.1.11/src/win/wwnd.c

why are there separate   if ( message==   statements, then directly after 
them there is a switch() ?
wouldn't it be efficient just to put them in the switch also ?

---snippet begins---

/* directx_wnd_proc:
 *  Window procedure for the Allegro window class.
 */
static LRESULT CALLBACK directx_wnd_proc(HWND wnd, UINT message, WPARAM 
wparam, LPARAM lparam)
{
   PAINTSTRUCT ps;

   if (message == msg_call_proc)
      return ((int (*)(void))wparam) ();

   if (message == msg_suicide) {
      DestroyWindow(wnd);
      return 0;
   }

  switch ( message )
