Licence terms of libstdc++-v3/porting.texi

[Richard Kenner]

        I wonder sometimes about the exact legal status of licensing. Just
        putting text into a file does not create a licensing or copyright
        statement of legal fact.

    It does, if the person making the statement is legally authorized to
    decide the policy.

Yes, but how do you know from the file who that person was let alone if they
are authorized to decide the policy?
