[lazarus] RedHat 9.0

[Rainer Hamann]

I've updated to RedHat 9.0 today. Lazarrus run fine, but when I start the 
application, it shows the main form and crashes. Selecting "Start/compile 
everything" ends at   
SW_SHOWNORMAL:
    begin
      gtk_window_deiconify(GtkWindow);
      gtk_window_unmaximize(GtkWindow);
    end;
in gtkwinapi.inc with the error message "identifier not found 
gtk_window_deiconify".
