I'm trying to compile something with nanotime(9), which simply states
that I need to include sys/time.h - nothing about libraries to
include. Unfortunately when I compile, I get linker errors regarding
nanotime in both freebsd and windows/cygwin - so the problem is
probably my use of the nanotime library and not the platform:

FreeBSD
========================================
[sjss@elrond ~/dev/numbench]$ gcc numbench.c

========================================

I tried adding a few libraries that might be useful: -lc -lm -lmd
-lpthread, but with no luck. I figured I'd try to find what library it
is in, but couldn't (strings /lib/* | grep nano; string /usr/lib/* |
grep nano). I could only find nanosleep, and a few other non-nanotime
references.

My includes (shouldn't be the problem):
#include <stdio.h>
#include <stdlib.h>
#include <sys/time.h>
#include <string.h>

How do I solve this issue?

Thanks,
