Ha, as ususal I cant see the forest for the trees.

They arose out of the dim distant times of yore. LibA was a Martin
Fowler inspired "business object" library from his Object Database
Impedance days. LibB was just a bunch of business domain utilities. In
those days LibA (the business object library) had a dependancy on LibB
for some calculations. Racently LibB (the utility library) got
"expanded" with a new bunch of functions, some of which depend on
accessing a related business object. Hence the circle.

Funny thing is, we have used and changed both of them for about a year
with no problems. It was just now when I am setting up a new software
repository that I hit the problem as neither executable exists.

And as usual you are correct, it is non-sense. I will have to
merge/split the circular functions into a new architecture.

Thanks, I obviously need a few kilo-jolts to the cranial area these
days to get out of a stuck thinking mode or two.)
