I did look at it, and it looked fine. I apologize for not responding
to the group about that.  I have many other things going on. :-(

What's clear is:

1. The scripts are poorly written. They should be fixed no matter what.

2. Haritha and company could use some external help in doing that
   (consultant, Ed, whatever, but inappropriate to the list).

3. There is *some* difference between the environments, given the
   change in runtimes between the same gawk binary (3.1.6) on
   both systems.  Trying to isolate that is also inappropriate to
   the list.

I'm NOT saying "let's leave the user out in the cold". I'm simply
asking that discussion and further attempts to help be done
elsewhere.
