2202	* Name : BOOL WIN32API AnyPopup
2203	* Purpose : The AnyPopup function indicates whether an owned, visible,
2204	* top-level pop-up, or overlapped window exists on the screen. The
2205	* function searches the entire Windows screen, not just the calling
2206	* application's client area.
2207	* Parameters: VOID
2208	* Variables :
2209	* Result : If a pop-up window exists, the return value is TRUE even if the
2210	* pop-up window is completely covered by other windows. Otherwise,
2211	* it is FALSE.
2212	* Remark : AnyPopup is a Windows version 1.x function and is retained for
2213	* compatibility purposes. It is generally not useful.
2214	* Status : UNTESTED STUB
2215	*
