re PR c++/23689 (Malformed typedef silently ignored)

Browse Source 
cp/:
	PR c++/23689
	* decl.c (check_tag_decl): Added new warning for typedef ignored
	when it precedes an otherwise valid non-typedef declaration.
testsuite/:
	PR c++/23689
	* warn/ignored_typedef.C: New.
	* init/ctor8.C: Added dg-warning to consume ignored typedef
	warning. 
	* template/typedef2.C: Ditto.  Moved dg-error onto its own line
	and added an explicit line number.
