+  * harbour/src/rtl/arc4.c
+    ! changed size parameter passed by reference to sysctl() to size_t
+    ! fixed WINCE builds
+    % enable pid checking only in *nix systems.
+      If system does not support fork() or compatible operation
+      (i.e. vfork(), clone()) then PID checking is completely useless.
+
+  * harbour/src/rtl/gtwvt/gtwvt.c
+    * pacified WINCE warnings
+
+  * harbour/contrib/rddads/adsx.c
+    ! fixed potentially uninitialized pTag variable
