Changes between 0.9.4 and 0.9.5 [xx XXX 1999]
*) Enhanced support for Alpha Linux is added. Now ./config checks if
the host supports BWX extension and if Compaq C is present on the
$PATH. Just exploiting of the BWX extention results in 20-30%
performance kick for some algorithms, e.g. DES and RC4 to mention
a couple. Compaq C in turn generates ~20% faster code for MD5 and
SHA1.
[Andy Polyakov]
*) Add support for MS "fast SGC". This is arguably a violation of the
SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
weak crypto and after checking the certificate is SGC a second one
