* ext/socket/socket.c (socket_s_ip_address_list): Fill sin6_scope_id
  if getifaddrs() returns an IPv6 link local address which
  sin6_scope_id is zero, such as on OpenIndiana SunOS 5.11.

* ext/socket/extconf.rb: Set close_fds false for Cygwin.
  Cygwin doesn't support fd passing.
  This enables socket extension library cross-compilable by default.

* ext/socket/socket.c (socket_s_ip_address_list): Cast EXTRA_SPACE as
  int.  This suppress a warning.

* ext/socket/ancdata.c (ancillary_inspect): Don't call
  anc_inspect_ipv6_pktinfo if !HAVE_TYPE_STRUCT_IN6_PKTINFO.
  anc_inspect_ipv6_pktinfo is not defined in the case.

* ext/socket/ancdata.c (bsock_recvmsg_internal): Add a cast to
  suppress warning.
  Bionic defines socklen_t as int.
  Bionic defines msg_controllen as unsigned int (__kernel_size_t)
  instead of socklen_t as POSIX.

* ext/readline/readline.c (insert_ignore_escape): Add a cast to
  unsigned char * before dereference.
  This suppress a warning on Cygwin.
