Is there an application that depends on this very strange implementation
detail? Besides, the messages in the ok() calls sometimes are wrong. Also,
you shouldn't test against TRUE/FALSE directly.

Do you have any good idea?
Thank you.

Is there any reason that you care about the size limit? In the most cases you
shouldn't unless there is an application that depends on particular behaviour.

Compare what the calls below are supposed to do and what ok() actually reports:
in case of a failure.

+        ret = CreateDirectoryA(tmpdir, NULL);
+        todo_wine ok(ret == FALSE,
+                     "CreateDirectoryA(%s) failed err=%d\n", tmpdir, GetLastError());
+        ret = RemoveDirectoryA(tmpdir);
+        todo_wine ok(ret == FALSE, "RemoveDirectoryA should always succeed\n");

ok(ret, ""); or if (!ret, ""); are commonly accepted solutions.
