bsdi4: sys/sockettytpes.h has socklen_t decl.  include sys/sockettypes.h
	from sys/socket.h and netinet/in.h.  netdb.h includes netinet/in.h
openbsd: sys/types.h has socklen_t decl.  netdb.h includes sys/types.h
freebsd4/netbsd: sys/socket.h has socklen_t decl.  netdb.h has does not have
	socklen_t decl.
