  *) OpenSSL 1.0.0 sets SSL_OP_ALL to 0x80000FFFL and OpenSSL 1.0.1 and

     1.0.1a set SSL_OP_NO_TLSv1_1 to 0x00000400L which would unfortunately

     0x10000000L Any application which was previously compiled against

     OpenSSL 1.0.1 or 1.0.1a headers and which cares about SSL_OP_NO_TLSv1_1

     will need to be recompiled as a result.
