	* exp_ch3.adb (Expand_N_Object_Declaration): When a class-wide
	object is declared, it is rewritten as a renaming of an dynamic
	expression that wraps the initial value.  The renaming declaration
	is first given an internal name, to prevent collisions with the

	the original one. the modification of the name must preserve
	the source location of the original, to prevent spurious errors
	when compiling with style checks if the declaration involves
	more than one entity.
