--- Comment #1 from David Edelsohn <dje at gcc dot gnu.org> ---
Where is __GTHREADS defined now?
-#include <bits/c++config.h>
...
+#ifdef __GTHREADS
// A single mutex controlling emergency allocations.
__gnu_cxx::__mutex emergency_mutex;
+ using __scoped_lock = __gnu_cxx::__scoped_lock;
+#else
+ int emergency_mutex = 0;
+ struct __scoped_lock { explicit __scoped_lock(int) { } };
+#endif
