2179	* Name : BOOL WIN32API AnyPopup
2180	* Purpose : The AnyPopup function indicates whether an owned, visible,
2181	* top-level pop-up, or overlapped window exists on the screen. The
2182	* function searches the entire Windows screen, not just the calling
2183	* application's client area.
2184	* Parameters: VOID
2185	* Variables :
2186	* Result : If a pop-up window exists, the return value is TRUE even if the
2187	* pop-up window is completely covered by other windows. Otherwise,
2188	* it is FALSE.
2189	* Remark : AnyPopup is a Windows version 1.x function and is retained for
2190	* compatibility purposes. It is generally not useful.
2191	* Status : UNTESTED STUB
2192	*
