OSSAL/CC license of xMule parts

[Daniel Leidert <daniel.leidert.spam@gmx.net>]

Hello,

I'm currently preparing an updated xMule package and found a statement,
which sounds a bit problematic. But I'm not a lawyer, so I ask you. E.g.
xLibs/DynPrefs/DynamicPreferences.cpp states:

// This file is dually licensed under the terms of the following licenses:

//   * See the included License.OSSAL for complete details.
//   * Key points:

//          (ex: the GPL).

I'm not sure of any of these licenses is DFSG-free. AFAIK the CC
licenses are considered non-free and I'm concerned about the OSSAL too
(that forbids linking against GPLed libraries). And the exceptions don't
seem to allow Debian to link against GPLed libraries.

Can you clarify the situation?
