[PATCH] ppc64 utmp changes

[Roland McGrath]

As Jakub pointed out, `struct timeval32' is a name space problem.  I would
really like to avoid adding new published types with kludge names (even
when prefixed by __ to avoid standard name space issues).  Is there any
other place that might use struct timeval32?  Would it work to just make it
an anonymous struct inside struct utmp/utmpx?

Is there anything but the struct timeval32 definition that would ever
use __time32_t and __suseconds32_t?
