Where is the right spot to apply an elaboration pragma to a library level subprogram?  GNAT (20210519-103) complains that in the below code C cannot with subprogram A.B because it's not Pure, but it certainly appears to be, and no amount of shuffling around the pragma in B seems to placate it.  Playing with the declaration of T seems to change the behavior; is GNAT is just misreporting a different error?

Thanks

package A is
  pragma Pure;  
  type T is limited null record;
end A;

procedure A.B (x : T) is
  pragma Pure; -- is this the right spot?
begin
  null;
end A.B;

with A.B;  -- error: cannot depend on "B" (wrong categorization)
package C is
  pragma Pure;
end C;
