The source code for the AVL-tree has been taken from the Ubiqx module library. This library is Copyright (C) 1991-1998 by Christopher R. Hertel <crh@ubiqx.mn.org> and distributed under the GNU Library General Public License (LGPL). That means that you can use them for free, and include them with your own code even if the latter is commercial or shareware.
It also features several other useful things and can be obtained from htpp://www.interads.co.uk/~crh/ubiqx/index.html. Different to the source code included with Vahunz, the version you can obtain from there is a lot more legible.
