(struct lastlog)
(struct utmp)
(struct utmpx)

When mentioning #if stuff, write it like this:

Check [__WORDSIZE_TIME64_COMPAT32] instead of 
[__WORDSIZE == 64 && __WORDSIZE_COMPAT32].

> 	* sysdeps/powerpc/powerpc32/bits/wordsize.h (__WORDSIZE_COMPAT32):

I didn't realize this was the only use of __WORDSIZE_COMPAT32.
Since it is, I think this is fine.  But the maintainers for all
the affected machines should have an opportunity to object.

> +#ifdef __x86_64__
> +# define __WORDSIZE_TIME64_COMPAT32		1
> +# define __WORDSIZE_NO_STATVFSBUF_F_UNUSED	1

__WORDSIZE_NO_STATVFSBUF_F_UNUSED is unrelated to this change and does not
belong in the same commit.
