    c++: using from enclosing class template [PR105006]

    Here, DECL_DEPENDENT_P was false for the second using because Row<eT> is
    "the current instantiation", so lookup succeeds.  But since Row itself =
has
a
    dependent using-decl for operator(), the set of functions imported by t=
he
    second using is dependent, so we should set the flag.

            PR c++/105006

    gcc/cp/ChangeLog:

            * name-lookup.cc (lookup_using_decl): Set DECL_DEPENDENT_P if
lookup
            finds a dependent using.

    gcc/testsuite/ChangeLog:

            * g++.dg/template/using30.C: New test.=
