Yes, but I was wondering whether I could tell the compiler not to generate
this code as I'm producing static initialisation here.

I've already mentioned this in an earlier part of the thread.

This is my code:

  type T_SPB is
    record
      ...
    end record;

  type T_SPB_PTR is access T_SPB;

  SP_Block : T_SPB;
  for SP_Block'Address use System'To_Address(16#80001000#);
  -- Tell the compiler that this record is defined elsewhere.
  -- Stops the compiler from producing a warning.
  pragma Import(Ada, SP_Block);

The compiler still generates that code.

Luke.
