A little off topic, but this code from
http://rubygems.rubyforge.org/svn/trunk/lib/rubygems/config_file.rb

      if RUBY_VERSION > '1.9' then
        SHGetFolderPath = Win32API.new 'shell32', 'SHGetFolderPath',
'PLPLP',
                                       'L', :stdcall
...
      else
        SHGetFolderPath = Win32API.new 'shell32', 'SHGetFolderPath',
'LLLLP',
                                       'L'
...
      end

Seems to show a difference in parameters between 1.9 and
1.8....anybody have any clue what is going on here?
Thanks.
