revisted my 8.15 package in detail. Seems that two years ago I had already
done something special for coreutils - so my apology - not a bug, just
something in the way. I will find a way to make it transparent for installp.

My question: once done, would you be interested in what I have done to
include either in an AIX INSTALL or README?
