+ * value.h: Created oload_search_type enum.
+ (find_overload_match): Use oload_search_type enum.
+ * valops.c (find_overload_match): Support combined member and
+ non-member search.
+ * eval.c (evaluate_subexp_standard): Calls to
+ find_overload_match now use oload_search_type enum.
+ (oload_method_static): Verify index is a proper value.
+ * valarith.c (value_user_defined_cpp_op): Search for and handle
+ both member and non-member operators.
+ (value_user_defined_cpp_op): New function.
+ (value_user_defined_op): New function.
+ (value_x_unop): Use value_user_defined_op.
+ (value_x_binop): Ditto.
+ * cp-support.c (make_symbol_overload_list_using): Added block
+ iteration.
+ Add check for namespace aliases and imported declarations.
+
2010-06-07 Jan Kratochvil <jan.kratochvil@redhat.com>
