+     1.0.1a set SSL_OP_NO_TLSv1_1 to 0x00000400L which would unfortunately
+     mean any application compiled against OpenSSL 1.0.0 headers setting
+     SSL_OP_ALL would also set SSL_OP_NO_TLSv1_1, unintentionally disablng
+     TLS 1.1 also. Fix this by changing the value ot SSL_OP_NO_TLSv1_1 to
+     0x10000000L Any application which was previously compiled against
