GPLv2 and Apache v2 are not compatible due to the patent grants, so I think the Apache v2 licensed code ought to be covered by another license or else it would be a breach of copyright. In general if you mix up BSD licensed software with GPL code, the combined program is considered a derivative and it's distributed under the GPL itself. The original BSD-licensed files are still under the BSD, but anything that directly refers to GPL code (i.e., glue code, anything that #include s a GPL header) is under GPL too.
