Ok guys, this i s pure theory. What may happen if anyone changes or 
extend some part of code? And what happens if anyone include GPL source 
code in an embedded project and he don't say that? In practice it is 
virtually impossible to be sure that nobody includes some source code 
parts extracted from other source codes (not only gpl, lgpl or open source).
