SubjectRe: Compiling C++ kernel module + Makefile

In fact, in Linux we did try C++ once already, back in 1992.

It sucks. Trust me - writing kernel code in C++ is a BLOODY STUPID IDEA.

The fact is, C++ compilers are not trustworthy. They were even worse in
1992, but some fundamental facts haven't changed:

- the whole C++ exception handling thing is fundamentally broken. It's
_especially_ broken for kernels.
- any compiler or language that likes to hide things like memory
allocations behind your back just isn't a good choice for a kernel.
- you can write object-oriented code (useful for filesystems etc) in C,
_without_ the crap that is C++.

In general, I'd say that anybody who designs his kernel modules for C++ is
(a) looking for problems
(b) a C++ bigot that can't see what he is writing is really just C anyway
(c) was given an assignment in CS class to do so.

Feel free to make up (d).
