In dired put the cursor upon cat.1.gz, and do = /tmp, i.e.,
(dired-diff "/tmp" nil)
which gives
diff -c -L /tmp -L /usr/share/man/man1/cat.1.gz /tmp /tmp/jka-com6714mTn

which would have been fine, if indeed there was a file named
/tmp/cat.1.gz, and its contents were the same, but there was no such
file. emacs-version "22.1.1".
P.S., you are using some secret undocumented private or erroneous diff
"-L" option. I can find a --L... but no -L.

Please try the following test.
In a directory with a .gz file in it, run dired.
Now place the cursor upon it and hit = /tmp
I.e., (dired-diff "/tmp" nil)
Note how it gives
diff -c -L /tmp -L /tmp/test/a.gz /tmp /tmp/jka-com9912y4f

But since what we wanted was the equivalent of doing
$ zdiff -c /tmp file.gz
which gives
diff: /tmp/file.gz: No such file or directory
That means that dired-diff blows it when one uses the shorthand /tmp
for /tmp/file.gz if there is no /tmp/file.gz.
Instead of detecting the missing file, it gives the all clear signal.
