Remove comments,different result.
You were already told once by Kyryl to update your TCC version or let us
know what platform and TCC version you're using. You still haven't done
either. It is impossible to help you without more information, though
Kyryl's suggestion of update your version of TCC is almost certainly the
correct one. (Alternatively, did you write your own libc and get printf
format string handling totally wrong?)

It would be near unbelievable if TCC couldn't correctly handle such a
simple program. But of course, it does.

It's the same problem as in previous test case - format
is for long long but the value passed is long.

So it's not a problem with tcc.

BTW, 247414872441159679 = 0x36efe840000ffff
