2007-08-14  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch4.adb (Try_Class_Wide_Operation): use base type of first
	parameter to determine whether operation applies to the prefix.
	(Complete_Object_Operation): If actual has an access type and
	controlling formal is not an in_parameter, reject the actual if it is
	an access_to_constant type.
	(Try_Primitive_Operation): If the type of the prefix is a formal tagged
	type, the candidate operations are found in the scope of declaration of
	the type, because the type has no primitive subprograms.
	(Analyze_Selected_Component): If prefix is class-wide, and root type is
	a private extension, only examine visible components before trying to
	analyze as a prefixed call.
	Change Entity_List to Type_To_Use, for better readability.
	(Has_Fixed_Op): Use base type when checking whether the type of an
	operator has a user-defined multiplication/division
	(Check_Arithmetic_Pair): Use Ada 2005 rules to remove ambiguities when
	user-defined operators are available for fixed-point types.

	operations in Derive_Subprograms.
	(Collect_Previous_Instances): new procedure within of
	Load_Parent_Of_Generic, to instantiate all bodies in the compilation
	unit being loaded, to ensure that the generation of global symbols is
	consistent in different compilation modes.
	(Is_Tagged_Ancestor): New function testing the ancestor relation that
	takes progenitor types into account.
	(Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
	traversing over the primitives of the formal and actual types to locate
	any abstract subprograms of the actual type that correspond to a
	nonabstract subprogram of the formal type's ancestor type(s), and issue
	an error if such is found.
	(Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,
	Instantiate_Package_Body, Instantiate_Subprogram_Body):
	Remove bogus guard around calls to Inherit_Context.
	(Reset_Entity): If the entity is the selector of a selected component
	that denotes a named number, propagate constant-folding to the generic
	template only if the named number is global to the generic unit.
	(Set_Instance_Env): Only reset the compilation switches when compiling
	a predefined or internal unit.
