+ * cp-namespace.c (find_symbol_in_baseclass): Call
+ cp_lookup_symbol_in_namespace instead of cp_lookup_symbol_namespace.
+ Check result of call to lookup_symbol_static.
+ Call lookup_static_symbol_aux unconditionally.
+ Call check_typedef on base types before accessing them.
+ (cp_lookup_nested_symbol): Fix comment.
