I suggest:
return std::tie(__x._M_thread.p, __x._M_thread.x)
< std::tie(__y._M_thread.p, __y._M_thread.x);
+#else
friend bool
operator<(thread::id __x, thread::id __y) noexcept
- { return __x._M_thread < __y._M_thread; }
-
+ { return __less<native_handle_type>::_S_less(__x._M_thread,
__y._M_thread); }
+#endif

What's this?
