You are wrong. It does not compile, neither in delphi, nor in FPC.
D is not found, because 'A' resolves to the local a, and then the 
search is stopped.

-----------------------------------

unit a;

interface

Var
  D : Integer;

implementation 

end.  
-----------------------------------

unit b;


interface
uses a;

Type
  T = Record
    C : integer;
  end;

Implementation

Procedure Doit;

Var
 A : T;

begin
  A.C:=1;
  A.D:=2;
end; 

end.
