That's similar to the situation where I found that Cygwin's patch doesn't work,
the patch file had some ^M, the file to patch didn't and patch 2.5.8 fails where
version 2.5.4 works and the CR are not added to the patched file.

Try version 2.5.4 it probably works already.

There is no Windows standard, if you use Notepad you end with CR-LF endings, if
you use Wordpad you end with LF endings (or a mixture), in Word you can choose,
...  Emacs can be configured but that is the user option not a standard.
