A far better alternative is to get sources for `patch'
(v2gnu/pat21s.zip) and debug this problem.  I'm guessing that the
DOS-specific code there which handles backing up breaks on LFN
platforms.  The best solution is to make `patch' execute the original
Unix code when _USE_LFN returns non-zero, instead of ifdef'ing that
code away at compile time.

If you decide to work on that, please post the patches here when you
find a way to make it work with both LFN=y and LFN=n.  Thanks.

Huh?  How about typing this:

		info utils redir

It even shows you an example that uses both -o and -eo.  Doesn't the
above command work for you?

Yes.  See the docs.
