Is this entirely unique to FreeBSD, or will it apply to Dragonfly and other BSDs? If the latter, this should be if is_bsd() && !is_apple().

I checked the manual, found that they share the same c struct in the first 4 field, but not sure the behaviour is consistent or not.
I will install VMs and try later.

The behavior is same on NetBSD and Dragonfly. But OpenBSD will get compilation error with
#include <link.h>. (link.h is described on OpenBSD's manual, seems there are some syntax error in the header file)
I decide to use f is_bsd() && !is_apple().

On more question: is sutable to use @static macro here? I just found that the if is_linux section in this file do not use @static. what is the reason?

You don't need @static at the top level 99% of the time since that's already what the branch is doing.
