    c++: noexcept-spec from nested class confusion [PR109761]

    When late processing a noexcept-spec from a nested class after completion
    of the outer class (since it's a complete-class context), we pass the wrong
    class context to noexcept_override_late_checks -- the outer class type
    instead of the nested class type -- which leads to bogus errors in the
    below test.

    This patch fixes this by making noexcept_override_late_checks obtain the
    class context directly via DECL_CONTEXT instead of via an additional
    parameter.

            PR c++/109761

    gcc/cp/ChangeLog:

            * parser.c (cp_parser_class_specifier): Don't pass a class
            context to noexcept_override_late_checks.
            (noexcept_override_late_checks): Remove 'type' parameter
            and use DECL_CONTEXT of 'fndecl' instead.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp0x/noexcept78.C: New test.
