Libraries totally should not call exit and thus not err/errx,
and warn/warnx is… also questionable at best.

But modularised code that builds a shared object and a few
binaries using it? Why not.

The thing I don’t get is why changing __progname is desired,
but I guess everyone has use cases for something.
