2242	* Name : BOOL WIN32API AnyPopup
2243	* Purpose : The AnyPopup function indicates whether an owned, visible,
2244	* top-level pop-up, or overlapped window exists on the screen. The
2245	* function searches the entire Windows screen, not just the calling
2246	* application's client area.
2247	* Parameters: VOID
2248	* Variables :
2249	* Result : If a pop-up window exists, the return value is TRUE even if the
2250	* pop-up window is completely covered by other windows. Otherwise,
2251	* it is FALSE.
2252	* Remark : AnyPopup is a Windows version 1.x function and is retained for
2253	* compatibility purposes. It is generally not useful.
2254	* Status : UNTESTED STUB
2255	*
