	gcc/testsuite  : ChangeLog 
Added files:

Log message:
	PR c++/2204
	* config-lang.in (gtfiles): Add typeck2.c.
	* Make-lang.in: Tweak typeck2.c dependencies, and add rule for
	gt-cp-typeck2.h.
	* cp-tree.h: Declare complete_type_check_abstract.
	* typeck2.c (pat_calc_hash, pat_compare,
	complete_type_check_abstract): New functions.
	(abstract_virtuals_error): If the type is abstract, register the
	declaration within abstract_pending_vars for further checks.
	Inspect also dependent types. Handle IDENTIFIER_NODEs as decl.
	* decl.c (cp_finish_decl): Do not strip array types.
	(create_array_type_for_decl): Check for abstractness of the element
	type.
	(complete_vars): Call complete_type_check_abstract.
	* class.c (finish_struct): Prepare a list of virtual functions for
	template types, and call complete_vars on it to check for abstractness.
	
	PR c++/2204
	* g++.dg/other/abstract2.C: New test.
