Well, the BSD license only requires the headers to remain in the source 
and the binaries, it does not forbid adding more headers and licences. 
In fact, it doesn't say anything about how derivative work should be 
licensed, as the GPL does. So I should think that *adding* a GPL license 
to a file that already has a BSD license does not violate that license.

Isn't this whole discussion one big legal advice? ;-)
