It looks like that version of SunOS doesn't have the socklen_t typedef.
Try adding the line

typedef int socklen_t;

to nsock/src/nsock_config.h.in, then reconfigure and rebuild. Probably
it will build nsock, then fail somewhere else because there are other
places where socklen_t is used. We could add a configure check for it.
