Erm, you may want to read the current C standard (C99). This isn't an
extension, it's standard.

There's a reason why C++ doesn't support that (yet): C++ is a fork of
C90 (IIRC), so everything that evolved in C during the years is still
missing from C++.

You can do with your code whatever you want to:) I think it's just a
matter of practice: If C++ code shows up that is less error-prone than
C code, doesn't use unverifyable amounts of stack space during
constructor runs and is basically _superior_ to C code, that'll find
its way into the kernel. But if it's only as good as the C code, then
why should anybody bother implementing the neccessary stuff to link
C++ code (and to initialize it properly?)
