Ah-hah, so HPUX is not the only platform where qsort chooses to output
those tuples in the other order.  I feel better now ;-)

I will go ahead and modify the rules test to do an "order by" in
the select * from rtest_admin command, so that it generates
predictable results.

I think we have two choices here:

1. Try to improve configure's test for cpp-from-stdin some more, and add
to it the idea that it might have to fall back to calling /lib/cpp
directly if neither "$(CPP)" nor "$(CPP) -" work for reading from stdin.

2. Rewrite the shell scripts that are using this feature so that they
don't need cpp-from-stdin, but just use a temporary file and plain
$(CPP).  Then we can forget about testing for it in configure.

A quick "glimpse" shows there are only two shell scripts using
$(CPPSTDIN), so I think choice #2 is the way to go.  At this point in
the schedule, we need a high-probability-of-success fix, and tweaking an
autoconf test is never a high-probability affair until you've actually
run it on a lot of platforms.  Hacking the scripts might be ugly,
but it will work.
