Piping to windows command line .rb file doesn't work

If I do this:

> type cat.rb

I get this output:

print $stdin.readlines

If I do this:

> type cat.rb | ruby -e "print $stdin.readlines"

I get this output (NOTE, it’s the same):

print $stdin.readlines

If I type this command (.rb has been associated to ruby.exe on Win2K):

> type cat.rb | cat.rb

I get this output:

cat.rb:1:in `readlines': Bad file descriptor (Errno::EBADF)
    from cat.rb:1

Any ideas why this doesn’t work?

It’s a known feature (or bug) of cmd.exe. You’d better claim
to the vender rather than to us. We can do nothing about it at
all.
