I think that on w32 several things can happen. The main problem is the 
line endings and the ability of different patch.exe on w32 to handle 
them. I sent a link to my tests earlier. They are probably difficult to 
understand by just reading that page, I can't even remember myself anymore.

However I do have a suggestion: It would be good to have a function in 
emacs handling the problems with different line endings for patch. This 
could be used for diff-apply-hunk and other similar functions in ediff.

This function could do something like this:

  1) read the file(s) to patch and the patch.
  2) if line endings are the same and can be used by the tools just 
apply the patch
  3) otherwise write rewrite the files with new line endings as needed 
and apply the patch. Switch back to old line endings for the patched 
file if necessary.

Without something like this I think we can not get patch to work from 
emacs reliable on w32. It would be a benefit for other platforms be able 
to I believe.
