Ruby for Windows Problems - BUG??

the following routine...

 def readindex(path)
  puts path
  index = []
 if File.exists?(path) then
 happy = File.open(path)
  while true
   break if happy.eof
   raw = happy.read(5)
   bytes = []
   raw.each_byte {|c| bytes.push(c)}
   bytes.reverse!
   n = 0
   bytes.each {|i| n = n*256+i }
   shift=24-((n>>24) & 0x7f)
   n=(n & 0x00ffffff)  | 0x00800000
   index.push((n >>shift)-1) 
  end
  
      return index
else
 puts "NDX File not found."
end
end

works correctly in Linux version... 1.6.4 and in cgi-win version 1.6.5

but NOT in ruby 1.6.7 (2002-03-01) [i586-mswin32]

in 1.6.7 for mswin32 it doesn't return all the data, instead ending with a
-1 somewhere in the middle.  I think I am going to have to dump developing
apps for both the windows and linux versions, as there are too many
inexplicable differences.  Ideas?

Thanks,

Mark
