What we need to do is audit the code base for any file that doesn't 
carry an explicit copyright notice, and have the author(s) add explicit 
copyright/license statements to it.  This top level file is not a valid 
copyright statement IMHO in particular because it deals with things like 
"libqemu.a" which is poorly defined.

My understanding of LICENSE is that it is purely an explanation, not a 
licensing statement.  It was added by Fabrice and it covers code in the 
tree that was there before he added it that he didn't hold the copyright 
on so it's not a very strong statement.

It was his desire that libqemu.a be LGPL, that does not mean that it 
actually is...
