PR c++/14401

	* class.c (check_field_decls): Complain about non-static data
	members of reference type in unions.  Propagate
	CLASSTYPE_REF_FIELDS_NEED_INIT and
	CLASSTYPE_READONLY_FIELDS_NEED_INIT from the types of non-static
	data members.
	* init.c (perform_member_init): Complain about mbmers with const
	type that are not explicitly initialized.

	PR c++/14401
	* g++.dg/init/ctor3.C: New test.
	* g++.dg/init/union1.C: New test.
	* g++.dg/ext/anon-struct4.C: New test.
