I was not trying to start a discussion about the merrits of C vs C++.
I was simply responding to marco's comment that "C++ support ... of
kbuild seems to be incomplete / not working".
As for C++ vs C. I don't have anything against C++. I use it a lot

appropriate for the kernel though, but that's a whole other
discussion.
