There are several stupid things in the code you gave, I won't go into
those. Now, while opening the file, you request that external CR/LF pairs
be converted to an internal '\n'. However, in your file there are LFs that
are not preceeded by CRs, so in fact your file is invalid. At least I
wouldn't be too sure about this being an error, I think Cygwin itself can
also be configured whether its lineendings behaviour should match that of
DOS or of Unix. Disclaimer: I'd have to trace the code myself to see
what's wrong, but take these things into account.
