I do not quite understand.  This variable gets assigned the return values
from TLSv1_method() or SSLv23_method(), but the copy of ssl.h I have
declares them as:

    SSL_METHOD *SSLv23_method(void);	/* SSLv3 but can rollback to v2 */
    SSL_METHOD *TLSv1_method(void);		/* TLSv1.0 */

We would need to explain this change a bit better.
