     I was somewhat puzzled by this also. Yes.

     I am still digging into the issue.
     I thank you the thoughtful reply.

     I also suspect a linker issue here and the sad fact is that the GNU
  ld just will not suffice in this server. C'est la vie ici.

     I have to laugh at the "bulldozer" idea as you are likely quite 
correct there.

I can tell you that this morning I see :

Which seems to work like a charm and I do have a few patches.

What I would like to do is climb in and see what can be done to create a
pure ISO 9899:1990 clean code path. May be reduced in features but would
still work pretty much everywhere. Maybe.

Sure do wish I had my old Oracle support contract to update this server
a bit but they want a LOT of money for that.
