2157	* Name : BOOL WIN32API AnyPopup
2158	* Purpose : The AnyPopup function indicates whether an owned, visible,
2159	* top-level pop-up, or overlapped window exists on the screen. The
2160	* function searches the entire Windows screen, not just the calling
2161	* application's client area.
2162	* Parameters: VOID
2163	* Variables :
2164	* Result : If a pop-up window exists, the return value is TRUE even if the
2165	* pop-up window is completely covered by other windows. Otherwise,
2166	* it is FALSE.
2167	* Remark : AnyPopup is a Windows version 1.x function and is retained for
2168	* compatibility purposes. It is generally not useful.
2169	* Status : UNTESTED STUB
