         PR c++/5998:
         * decl.c (cxx_init_decl_processing): Re-enable built-in functions
         in the g++ front-end.
         (duplicate_decl): Allow redefinition of anticipated built-ins.
         Fix inlining problem by over-writing the old DECL_RTL.
         (lookup_namespace_name): Fail to find an identifier in the
         specified namespace if its still anticipated.
         (builtin_function_1): New function split out from builtin_function
         to create a builtin in the current namespace with given context.
         (builtin_function): Call builtin_function_1 to define the
         appropriate builtins in both the std and global namespaces.
         (select_decl): Don't test for anticipated decls here.
         (unqualified_namespace_lookup): Instead ignore them whilst
         searching through scopes and namespaces.
         * decl2.c (do_nonmember_using_decl): If a using declaration
         specifies an anticipated built-in function, mark it as no longer
         anticipated in that scope.
         (ambiguous_decl):  Avoid resolving to an anticipated decl.
         * lex.c (do_scoped_id): Fail to find an identifier in the global
         namespace if its still anticipated.
 
 Bye,
 Gwenole.
