* eval.c (rb_eval): ruby_frame->last_func may be null, if it's

called outside of a method.

* parse.y (arg): use INT2NUM, not INT2FIX for tUMINUS.

* parse.y (arg): unnecessary negative tPOW treatment.

* parse.y (tokadd_escape): wrong backslash escapement.

* parse.y (stmt,arg): too much void value check.

* parse.y (stmt,arg): need to check void value on rules which does
  not use node_assign().

* ext/socket/socket.c (ipaddr): need not to taint hostnames.

* range.c (range_include): should be based on "<=>", whereas
  member? still is based on "each".

* range.c (range_min,range_max): redefine methods based on "<=>".
