Björn,
this is what I get on building of

package body Gnat.Serial_Communications.Baud is
.
.
procedure Get_Divisor (Port : Serial_Port)
is
   function Toint is new Ada.Unchecked_Conversion  -- line 53
     (Source => Port_Data, Target => Integer);
begin
.
.

gprbuild -Paupdi.gpr
Compile
   [Ada]          g-secoba.adb
g-secoba.adb:53:17: premature use of incomplete type
g-secoba.adb:53:17: instantiation abandoned
g-secoba.adb:57:33: "toint" is undefined
gprbuild: *** compilation phase failed

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

And now I do get the compilers problem. the Port_Data type is only spelled out in the body of Gnat.Serial_Communications as an integer. So I cannot see it in the child.

Pity. So I will have to construct a hand crafted Serial_Communications package.

Thanks for your help.
