Hi, Paul,

Thanks for your speedy reply.

Good enough:

(But I've long been tempted to tender a suggestion that the
guessers should supply a version for z/OS as they do for other
OSes.)

Now, I'm in trouble.  The patch wouldn't apply, so I made the
changes by hand and re-did the diff -u.  Attached.

And it's been literally years since I did an autoconf.  It's
probably out of date.  And it couldn't find "configure.in".
Was I supposed to get one with the coreutils distribution?
I'll go hunt for a newer autoconf, and configure.in (any
pointers appreciated).  May take me several days.

Thanks again,
gil
