I've run C++ code in the kernel. You couldn't easily use: templates,
exceptions, global ctors, and sometimes you had to be careful with
automatic instantiation of things. I implemented only new and delete
and was able to get sample code to run in the kernel. I punted at
that point due to the pain in actually knowing if these things were
being used or not.
