Subject: find executables on windows

in linux i'd do something (un-tested) like:

   def find_bin bin
     bin = nil
     path = ENV['PATH'].split File::PATH_SEPARATOR
     path.each do |dir|
       b = File::join dir, bin
       return b if File::executable? b
     end
     bin
   end

what would the equivalient be in windows? should the above
work or do i need to check some other env vars?

cheers.
