(lookup_field_r): Call lookup_fnfields_slot instead of
lookup_fnfields_1.
* semantics.c (finish_member_declaration): Remove the check that
prevents USING_DECLs from being verified by
pushdecl_class_level. Call add_method for using declarations that
designates functions if the using declaration is in a template
class. Set DECL_IGNORED_P on class-scope using declarations.
* typeck.c (build_class_member_access_expr): Handle USING_DECLs.

declarations.

(supplement_binding_1): Call strip_using_decl on decl and
bval. Perform most of the checks with USING_DECLs stripped. Also
check that the target decl and the target bval does not refer to
the same declaration. Allow pushing an enum multiple times in a
template class. Adjustment to diagnose using redeclarations. Call
diagnose_name_conflict.
(push_class_level_binding): Call strip_using_decl on decl and
bval. Perform most of the checks with USING_DECLs stripped. Return
true if both decl and bval refer to USING_DECLs and are dependent.
