Quite.  Maybe my wording wasn't correct.

If the Issuer/Serial is the same for 2 certificates, but the certificates
are not the same, then my patch will return an error of
X509_V_ERR_DIFFERENT_SELF_SIGNED_CERT.

In the current code, X509_check_issued() would return X509_V_OK in that
situation because the only check made if no AKID is present, is that the
Issuer = Subject.
