[ruby-dev:22344] pack('N') broken on 64bit platforms

From: Minero Aoki <aamine@...>
Date: 2003-12-23 13:51:17 UTC
List: ruby-dev #22344
青木です。

64 ビットプラットフォーム上だと pack("N") の返り値が
常に "\000\000\000\000" になります。

  aamine@asv800 % cat t
  def f(n)
    p [n].pack('N')
  end
  f 1
  f 2
  f 3
  f 10
  f 100
  aamine@asv800 % ruby -v t
  ruby 1.8.1 (2003-12-22) [alpha-netbsd]
  "\000\000\000\000"
  "\000\000\000\000"
  "\000\000\000\000"
  "\000\000\000\000"
  "\000\000\000\000"

とりあえず以下のように修正して直るのを確認しましたが、
どうするのがよいでしょう。
