For referene, ``that'' is the following idiom:

| -	  if (wakeup_time.tv_nsec > 1000000000)
| +	  if (wakeup_time.tv_nsec >= 1000000000)
|             {
|               wakeup_time.tv_nsec -= 1000000000;
|               ++wakeup_time.tv_sec;
|             }

Would ``that'' go into time/time.h, to find its place in
/usr/include/time.h, guarded by __USE_GNU (like TIMEVAL_TO_TIMESPEC in
time/sys/time.h, for example) -- that is, for general consumption and
benefit?  Or should it be only an internal thing, thus go into
include/time.h, avoiding us to have to think about versioning and all
that?
