    c++: current inst name lookup within noexcept-spec [PR122668]

    Since we don't implement deferred noexcept-spec parsing of a friend
    declaration, the r15-2117 change diagnosing name lookup failure for the
    current instantiation ahead of time needs to be suppressed in this case.

            PR c++/114764

    gcc/cp/ChangeLog:

            * pt.cc (dependentish_scope_p): Return true for the current
            instantiation from within an immediately parsed noexcept-spec.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp0x/noexcept91.C: New test.
