          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal

According to

---------------------------------------
The fourth point, the VERS 1.0 version being referred to in the VERS 2.0
definition, is not really important in symbol versioning. It marks the
predecessor relationship of the two versions and it is done to maintain the
similar- ities with Solaris’ internal versioning. It does not cause any problem
it might in fact be useful to a human reader so predecessors should always be
mentioned.
-----------------------------------------

At least this human finds it incredibly confusing to have information in the
file that is not clearly marked as comment and yet is supposed to have no
impact.

We should at least delete the code that sets the parent version since it is not
used.
