changes in sbcl-1.0.4 relative to sbcl-1.0.3:
+ * new platform: experimental support for x86-64/darwin (MacOS).
* incompatible change: the thread-safe (on most platforms) getaddrinfo
and getnameinfo sockets functions are used instead of gethostbyaddr
and gethostbyname, on platforms where the newer functions are available.
