Subject: * parse.y (newline_node): do not use NODE_NEWLINE node anymore,   use
 NEWLINE flag instead.

* ext/socket/socket.c (sock_gethostbyname): returns host if
  ai_canonname is NULL. (ruby-bugs PR#1243)

* parse.y (block_append): update nd_end for "real" head node.
  [ruby-list:39058]

* marshal.c (w_class): should not dump singleton class.
  [ruby-dev:22631]
