Close enough.  HP did the work separately, Cygnus attempted to merge it.

Probably right.

Correct.  In fact, this test has always been wrong, and AFAIK, 
it could never ever ever have passed.  I don't understand how
it has existed as such.

I don't understand why it isn't a FAIL on RH7.  The output is
identical to the failing output on Solaris.
