The change results in incorrect information.  I am guessing that "@*ovcs_id"
would not be valid syntax (I have not tried it).  The changed version says
that the pointer ovcs_id is changed to zero, but the actual action is to
change the value pointed to by ovcs_id is changed to zero.  Is there a
valid syntax to say this?
