Thanks for your response, Jonas - 

There are things in UNIT_TWO on which UNIT_ONE depends.
Removing "uses unit_two;" results in a compiler error:

  Undeclared identifier 'SOMETHING'

That "SOMETHING" is declared in UNIT_TWO 

But putting an empty initialization section in UNIT_TWO 
eliminates the message.

I will try to see if I can come up with a simple example to 
reproduce the problem, but the project is about 3800 lines, 
spread across twelve different units, so it is a bit too 
large to post it here...
