2245	* Name : BOOL WIN32API AnyPopup
2246	* Purpose : The AnyPopup function indicates whether an owned, visible,
2247	* top-level pop-up, or overlapped window exists on the screen. The
2248	* function searches the entire Windows screen, not just the calling
2249	* application's client area.
2250	* Parameters: VOID
2251	* Variables :
2252	* Result : If a pop-up window exists, the return value is TRUE even if the
2253	* pop-up window is completely covered by other windows. Otherwise,
2254	* it is FALSE.
2255	* Remark : AnyPopup is a Windows version 1.x function and is retained for
2256	* compatibility purposes. It is generally not useful.
2257	* Status : UNTESTED STUB
2258	*
