I was able to build the most recent VirtualBox sources using gcc-5 20150410 from Debian experimental without applying any further patches. A few days ago we fixed a couple of warnings in the VirtualBox source code (see for example r55192). I hesitate to change the configure script to allow gcc-5 as compiler for now, maybe we do this for the final 5.0 release. Frank -- Dr.-Ing.
