is instead given to gnutls_priority_init(3), which expects a priority string;
this behaviour is much closer to the OpenSSL behaviour. See:
- http://www.gnu.org/software/gnutls/manual/html_node/Priority-Strings.html
+ http://www.gnutls.org/manual/html_node/Priority-Strings.html
for fuller documentation of the strings parsed. The three gnutls_require_*
options are still parsed by Exim and, for this release, silently ignored.
