Obtaining access to protected object

[Maciej Sobczak <see.my.homepage@gmail.com>]

Consider 9.4-21/2:

"Within the declaration or body of a protected unit other than in an
access_definition, the name of the protected unit denotes the current
instance of the unit"

I understand that this allows me to obtain the access to the current
object (the "this" access) of the protected object.
Let's try:

   protected type P is
      procedure Foo;
   end P;

   protected body P is
      procedure Foo is
         Ptr : access P;   -- P denotes the type P
      begin
         Ptr := P'Access;    -- here P denotes the "this" instance of
P
      end;
   end P;

This is what GNAT has to say about it: ""Access" attribute cannot be
applied to type".
As far as I understand, this is in conflict with the AARM paragraph
mentioned above.

Am I doing something wrong or is it a compiler bug?
