    c++: global-namespace-qualified var after class def [PR90107]

    Here we wrongly reject the definition of "::N::a"

      struct A;
      namespace N { extern A a; }
      struct A {} ::N::a;

    because our code to diagnose a missing ; after a class definition doesn=

    realize that :: can follow a class definition.

            PR c++/90107

    gcc/cp/ChangeLog:

            * parser.cc (cp_parser_class_specifier_1): Accept :: after a cl=
ass
            definition.

    gcc/testsuite/ChangeLog:

            * g++.dg/parse/qualified6.C: New test.=
