binmode is for binary files.

CRLF (\r\n Windows) and LF (\n *nix) are for text files.

I think you are confusing those two issues. They are not related. When 
reading a file you could

while (<IN>) {
   s/[\r\n]+$//;

to remove those characters regardless of which format any given file was 
written in.

Does that help?   :)
