I've read the following in the README file in source/TeX/texk/web2c
directory:

==================
Web2c is free software.  The files I wrote (originally for the Free
Software Foundation) are covered by the GNU General Public License --
see the files COPYING*.  Knuth's original sources are covered by their
own copyright -- see the beginning of tex.web, mf.web, etc.  You can get
the original files on their own from CTAN:/systems/knuth; you can get
MetaPost from ftp://netlib.att.com/netlib/research/metapost.tar.Z
(see also http://cm.bell-labs.com/who/hobby/MetaPost.html).
==================

Also, tex --version says:

TeX 3.141592 (Web2C 7.5.3)
kpathsea version 3.5.3
Copyright (C) 1997-2004 D.E. Knuth.
Kpathsea is copyright (C) 1997-2004 Free Software Foundation, Inc.
There is NO warranty.  Redistribution of this software is
covered by the terms of both the TeX copyright and
the GNU General Public License.
For more information about these matters, see the files
named COPYING and the TeX source.
Primary author of TeX: D.E. Knuth.
Kpathsea written by Karl Berry and others.

Nowhere i see the LGPL here. So, it is very well possible that XeTeX
is violating the GPL.

Best,
