-- When compiling the body of a package, both routines are called in

-- body, create an implicit body at the end of the current declarative
-- part to activate those tasks.
procedure New_Private_Type (N : Node_Id; Id : Entity_Id; Def : Node_Id);
-- Common processing for private type declarations and for formal
-- private type declarations. For private types, N and Def are the type

-- definition.
procedure Uninstall_Declarations (P : Entity_Id);
-- At the end of a package declaration or body, declarations in the
-- visible part are no longer immediately visible, and declarations in
-- the private part are not visible at all. For inner packages, place
-- visible entities at the end of their homonym chains. For compilation
-- units, make all entities invisible. In both cases, exchange private
-- and visible declarations to restore order of elaboration.
