The presence of a copyright notice doesn't mean it is reflecting any
reality, especially in generated files. In the above example, there
isn't even anything to copyright besides the copyright notice itself. If
you redirect gdb output to a file, it will contain a copyright notice
from the FSF. It doesn't mean the file is copyrighted by the FSF.
Quite similarly, it's not because you found copyright strings by
grepping an EPS that some content in the EPS is actually under that
copyright. And even if there is content under that copyright, as someone
else said in the thread, it doesn't tell anything about the
corresponding license.
