If an incomplete_type_declaration includes the reserved word tagged,
then a full_type_declaration that completes it shall declare a tagged
type.

The error for T3 is detected, but not T1 or T2.

package pak1 is
   type T1 is tagged;
   type T2 is tagged;
   type T3 is tagged;
   protected type T1 is end T1;
   task type T2;
   type T3 is null record;
end pak1;

gnatmake -gnat05 pak1
gcc-4.1 -c -gnat05 pak1.ads
pak1.ads:4:09: full declaration of type "T3" defined at line 7 must be tagged

gnatmake -gnat05 pak1
gcc-4.3 -c -gnat05 pak1.ads
pak1.ads:4:09: full declaration of type "T3" defined at line 7 must be tagged
