systemd does not use C++, we are a C project.

We make sure superficially our C header files are compatible with C++,
but that's how far our support for C++ goes.

I have no experience with C++ exceptions and C stack frames. We have
no explicit support for any of it, so they are handled like in any
program where C++ is called from C contexts, and I figure there will
be plenty docs about that.
