* eval.c (svalue_to_avalue): v may be Qundef. This fix was

  suggested by Guy Decoux.

* hash.c (rb_hash_s_create): use rb_hash_aset() instead of calling
  st_insert() directly, to dup&freeze string keys.

* parse.y (yylex): proper error message for "@@0".

* parse.y (yylex): paren to parse_string() must be zero for
  unparenthesized strings.

* parse.y (str_extend): broken string when unterminated "#{".

* enum.c (enum_sort_by): had a bug in 1 element enumeration.
