+// Test for std::this_thread::sleep_for().
+/* For some reason MinGW's <thread> header seems to be broken.
+ *
+ * But it gets worse.  It looks as if we can include <thread> without problems
+ * in this configuration test.  Why does it break when MinGW users try to build
+ * the library, but succeed when we try it here?
+ *
+ * To try and get close to the situation in the library code itself, we try
+ * including some standard headers that we don't strictly need here.
