Or not? gnulib's nanosleep module will arrange for the -lrt and/or substitute code if your host lacks nanosleep(). There's also the gnulib xnanosleep module if you prefer a simpler interface. I'm not sure why you mention setitimer as well -- what facilities do you need other than sleeping? But if you merely want a high-resolution timer that is not subject to resetting or drifting, gnulib has a gethrxtime module with support for such timers under FreeBSD, Solaris, POSIX with CLOCK_MONOTONIC, etc. It also knows about -lrt. http://www.gnu.org/software/gnulib/ _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
