In strictly legal terms you are right. With re-licensing I meant "adding GPL licensed parts to otherwise BSD-licensed code", which technically retains the original license but makes it practically unusable. A similiar case arises when relicensing "GPLv2 or later" code as "GPL2 only". The original notice must be retained, but it isn't of much use in practical terms. Thiemo
