        Making Time::HiRes (dynamic)
Configuring Time::HiRes...
Have syscall()... looking for syscall.h... found <syscall.h>.
Looking for gettimeofday()... found.
Looking for setitimer()... found.
Looking for getitimer()... found.
You have interval timers (both setitimer and getitimer).
Looking for ualarm()... found.
Looking for usleep()... found.
Looking for nanosleep()... testing... found.
You can mix subsecond sleeps with signals, if you want to.
(It's still not portable, though.)
Looking for clock_gettime()... found.
Looking for clock_getres()... found.
Looking for clock_nanosleep()... NOT found.
Looking for clock()... found.
Looking for stat() subsecond timestamps...
Trying struct stat st_atimespec.tv_nsec...NOT found.
Trying struct stat st_atimensec...NOT found.
Trying struct stat st_atime_n...NOT found.
Trying struct stat st_atim.tv_nsec...NOT found.
Trying struct stat st_uatime...NOT found.
You do not seem to have stat subsecond timestamps.
