There was lots of discussion/flames back-and-forth with newbies requiring that modules be written in C++. This is what you get. Some of the C++ built-ins are not even global so the linker won't be able to find them if they are used. It's not just a matter of emulating 'new'. Parameter-passing 'by reference' also won't work so putting 'C' wrappers around stuff like they do in Dr. Jobbs and C/C++ Journal isn't going to work inside the kernel where there is no support.
