Copyrights on files

Someone has pointed out to me that we have non-PostgreSQL/Berkeley
copyrights on a number of files:

src/port/rint.c
* Copyright (c) 1999, repas AEG Automation GmbH

src/backend/port/dynloader/aix.c
* This is an unpublished work copyright (c) 1992 HELIOS Software GmbH
* 30159 Hannover, Germany

src/backend/port/dynloader/ultrix4.h
* Copyright (c) 1993 Andrew K. Yu, University of California at Berkeley
* All rights reserved.
... BSD copyright text follows

src/backend/utils/mb/Unicode/UCS_to_GB18030.pl
# Copyright 2002 by Bill Huang

I have emailed Andrew Yu to see if we can remove his line, but I
question whether the other people can be reached.

How should we handle this?
