I trust you understand what it means when libcurl can't verify the server
certificate? The server's certificate has been signed by a CA who's not
present in your CA store/bundle.

The exact string "self signed certificate" is stated by OpenSSL there (right?)
and I'm not familar with its exact internal logic for saying it is self
signed. The normal way to do self-signed certs is when you run a server with a
cert that is signed by your yourself and not by any known CA. Logically, a
client cannot verify a self-signed cert and thus it fails the check.
