Don't mess with \r\n yourself.

When running the code with the Cygwin perl, add the PerlIO layer ":crlf" to the respective file handles, and with the other perl, don't, because a native Windows perl already has the :crlf layer enabled.  (Actually, you should be able to simply add the layer in both cases, because due to the implementation details, the layer will only ever be once on the layer stack.)

This presumes the idea is to generate files with the native Windows newline style.  If you just want your scripts to work within either a Unix/Cygwin or a Windows enviroment (without exchanging files between both "worlds"), simply use \n and be happy.
