Detailed Description

Replacement getaddrinfo functions.

These functions are defined and used only if the configure cannot detect the standard getaddrinfo(), freeaddrinfo(), gai_strerror() and getnameinfo(). This avoids sprinkling of ifdefs.

FIXME: getaddrinfo() & getnameinfo() should return all IPv4 addresses provided by DNS lookup.
