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't
realize that :: can follow a class definition.
PR c++/90107
gcc/cp/ChangeLog:
* parser.cc (cp_parser_class_specifier_1): Accept :: after a class
definition.
gcc/testsuite/ChangeLog:
* g++.dg/parse/qualified6.C: New test.
