I'm assuming you do not want the value to be
visible neither in the private part nor in the
public part of the package specification?

Use a function then, and make the package pure,
if possible:

package P is

  pragma pure;

  type Thing is ...;

  function My_Constant return Thing;

  pragma Inline(My_constant);

end P;

Chances are that the compiler might be able to
act as if My_Constant was a simple constant.
