That's not a bug in the kernel per se, that's a bug in using that kernel header (written in C) in a compiler expecting C++ code. Which would make it a bug in xf86-video-virtualbox for not linking against a C-compiled object file. Granted, it'd be a heck of a lot more convenient if the kernel header files didn't use C++ keywords...but it *is* fundamentally a problem with compiling a source file using the wrong language. Like trying to read something in Portugese, except it was written in Spanish. It might work some of the time, but it'll catch you out eventually. -- :wq
