to apply.
This list is current as of:
- ==> 1.0.1b <==
-Plus SSL_OP_SAFARI_ECDHE_ECDSA_BUG from 2013-June patch/discussion on openssl-dev
-Plus SSL_OP_NO_TLSv1_3 for 1.1.2-dev
-Plus SSL_OP_NO_RENEGOTIATION for 1.1.1
+ ==> 1.1.1c <==
XXX could we autobuild this list, as with predefined-macros?
-Seems just parsing ssl.h for SSL_OP_.* would be enough.
+Seems just parsing ssl.h for SSL_OP_.* would be enough (except to exclude DTLS).
Also allow a numeric literal?
