+
+[A30] {UD} As the message says, relink the binary.  The problem is that
+very few symbols from the library can change in size and there is no way
+to avoid this.  _sys_errlist is a good example.  Occasionally there are
+new error numbers added to the kernel and this must be reflected at user
+level.
+
+But this does not mean all programs are doomed once such a change is
+necessary.  Such symbols should normally not be used at all.  There are
+mechanisms to avoid using them.  In the case of _sys_errlist, there is the
+strerror() function which should _always_ be used instead.  So the correct
+fix is to rewrite that part of the application.
+
+In some situations (especially when testing a new library release) it might
+be possible that such a symbol size change slipped in though it must not
+happen.  So in case of doubt report such a warning message as a problem.
