	* exp_ch3.adb (Make_Predefined_Primitive_Specs):
	Do not generate the profile of the equality operator if it has
	been explicitly defined as abstract in the parent type. Required
	to avoid reporting an spurious error.

	* sem_dim.ads, sem_dim.adb (Check_Expression_Dimensions): New
	procedure to compute the dimension vector of a scalar expression
	and compare it with the dimensions if its expected subtype. Used
	for the ultimate components of a multidimensional aggregate,
	whose components typically are themselves aggregates that are
	expanded separately. Previous to this patch, dimensionality
	checking on such aggregates generated spurious errors.
	* sem_aggr.adb (Resolve_Array_Aggregate): Use
	Check_Expression_Dimensions when needed.

	(Corresponding_Procedure): New attribute (applicable to E_Function).
	* exp_util.adb (Build_Procedure_Form): Link the function with
	its internally built proc and viceversa.
	* sem_ch6.adb (Build_Subprogram_Declaration): Propagate the
	attribute Rewritten_For_C and Corresponding_Procedure to the body.
	* exp_ch6.adb (Rewritten_For_C_Func_Id): Removed.
	(Rewritten_For_C_Proc_Id): Removed.
	* exp_unst.adb (Note_Uplevel_Ref): Use the new attribute to
	locate the corresponding procedure.
