2004-03-25  Thomas Quinot  <quinot@act-europe.fr>

	* sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
	attribute reference does not denote a subtype, it can be any
	expression that has a classwide type, potentially after an implicit
	dereference.  In particular, the prefix can be a view conversion for
	a classwide type (for which Is_Object_Reference holds), but it can
	also be a value conversion for an access-to-classwide type. In the
	latter case, there is an implicit dereference, and the original node
	for the prefix does not verify Is_Object_Reference.

	conversion of a discriminant-dependent component of a mutable object
	is one itself.
