...Hmm, yes it is.  I just re-tested without the manual define
and it autodetected flawlessly.

When I first ran configure with the TEST_MINUS_S_SH in it, I got a 
munged output line for that test.  (it ran together with the 
"testing for ls..." line after it.)

I quickly added a manual define and it went away. Now that I
take the manual define out and re-configure, it looks fine too.

It appears that I moved on too quickly. Drop that change.

I brought forward USE_PIPES from scp hanging problems in 2.3.0p1.
They still exist in the version I just built from today's cvs.

After completing a copy, the client returns a prompt, but the
session is still active (still has  "sh -c scp -t file", 
"scp -t file", and "sshd" active on the server, plus ssh command 
on client).

Typing an INTR on the client returns an error of "Killed by signal 2",
at which point everything exits.

To test it, I ran:

scp file localhost:file.2

I also tested scp from a remote 2.3.0p1 client with the same results.

Let me know if you can duplicate this or not.
