Drivative works of BSD'd code (derivative literary works [modulo the AFC
test] under copyright law) are subject to BSD. In source code form, such 
derivative works are subject to BSD and only the BSD -- you simply can't 
modify/extend/etc. original license (unless you're the copyright owner 
in original works).

Compilations ("mere agreegations" in GNU speak) are NOT subject to BSD.

Eh, as long as he didn't modify any BSD'd code, all his works are GPL'd 
and they are separate (literary) works from BSD'd (literary) works from 
"A". And a combination (compilation) of all those works is another 
non-derivative (under copyright law, not metaphysically) work and it is 
subject neither to GPL nor BSD.
