	* sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
	become local to the whole package.
	(Install_Limited_Withed_Unit): Instead of unchaining real entities if
	the package was already analyzed the new algorithm "replaces" the
	real entities by the shadow ones. This is required to ensure that
	the order of these entities in the homonym chains does not change;
	otherwise we can have undefined references at linking time because
	in case of conflicts the external name of the entities will have
	a suffix that depends on the order of the entities in the chain.
	(Remove_Limited_With_Clause): Complementary code that completes the
	new algorithm and replaces the shadow entities by the real ones.
	(Install_Limited_Withed_Unit): When unchaining entities before the
	installation of the shadow entities, only regular entities of the
	public part must be taken into account. This is required to
	keep this routine in synch with the work done by Remove_Limited_
	With_Clause
	(Install_Limited_With_Clause): Introduce implicit limited_with_clause
	even if unit is analyzed, because the analysis of the unit is
	idempotent in any case, and the limited view of the unit may have to
	be installed for proper visibility.
	(Expand_Limited_With_Clause): Even if the unit in the implicit
	with_clause has been analyzed already, a limited view of the package
	must be built for the current context, if it does not exist yet.
