These don't seem symmetric. Why don't we need an extern declaration for
__ctime_64 or for __ctime_64_r? If the code is correct, maybe a comment why?

No parentheses here (and similarly elsewhere).
+/* The C Standard says ctime (t) is equivalent to asctime (localtime (t)).
+ In particular, ctime and asctime must yield the same pointer. */
+ return asctime (__localtime64 (t));
Please indent the comment to be like what it was before.
Otherwise looks good; thanks.
