Do you set LFN=y?  If not, set it and try again.  If you do have LFN=y, 
set it to n and see if that helps.  Methinks this is some kind of LFN 
mishap.

Why are you trying to live dangerously?  Just let `redir' handle the
entire redirecting job, instead of relying on 4DOS: 

	redir -i diffs-t6 -o outfile -eo patch -p2

If this works, then both `redir' and `patch' live together in perfect 
harmony.

Explanation for the curious: when you use redirection symbols on the
command line, they actually redirect the input and output of `redir', not
of the program that `redir' runs.  You then rely on the intricacies (and
bugs) of the shell you use regarding the inheritance of the redirected
streams to child programs.  While this might well be a subject for a
post-doctorate, if you only need to make the damn thing work, I suggest to
stay away of this mess.

This is indeed the latest version.  I use it also.
