These variables are defined and actually used in a sense. The value of the
variable is at least changed/updated once but the value of the variable is not
in any case. Normally it is save to remove all occurence of the variable.
On the other side this behaviour means that there were some code changes, so
the code around the commented lines should be checked carefully if it makes
sense and if it is still meeded.
