  http://forum.sun.com/jive/thread.jspa?threadID=73150

  Solaris 10 では，/usr/sfw/lib/libstdc++.la や /usr/sfw/lib/64/libstdc++.la が空なのでたまに，

libtool: link: `libstdc++.la' is not a valid libtool archive

  などといってエラーが出るときがある．

  その場合の対処法．
  /usr/sfw/lib/libstdc++.la，/usr/sfw/lib/64/libstdc++.la に以下の内容を記述する．
