Well, GPL2 is a licence, not a copyright. I don't know what country you are in, whereas Giles was in the UK -- copyright issues are somewhat country-specific.

However, two recommendations:

  1. only give the year of the changes. They can overlap.
  2. only add your copyright statement to files you actually change (and not just change by adding a copyright statement but adding something with intellectual content).

This is all untested waters and let's hope it remains that way!
