Subject: ruby 1.8.1/cygwin: Writing text files (dos mode) broken?

I was recently running some tests before switching to ruby 1.8.1 on cygwin. I
found one problem that currently keeps me from installing ruby 1.8.1:

When writing text files they end up as unix files even though I explicitly
told setup.exe to use dos mode: 

f = File.new("test.txt","w")
f.puts("Where \n is the CR?")
f.close

Running above script on ruby 1.8.1 will create test.txt with only 0x0a (LF) 
as line delimiter. When using ruby 1.6.8 this correctly creates a dos-like 
text file (CR+LF)

My ruby app (a build engine) creates c/cpp headers and resource files to be 
used by cl.exe and friends - and some of them won't accept unix style files.

Maybe someone could verify/comment on that? Did I miss something here? IMHO 
line ending conversion should still be transparent to ruby scripts?

ps. Actually I think this is caused by io.c:line 4087 where cygwin_internal()
is used to unconditionally set file IO to binmode!?
