Interesting. According to POSIX: http://www.opengroup.org/onlinepubs/9699919799/functions/if_freenameindex.html It should be a real function. Could you report this as a OpenBSD bug? It does sounds as if this is something that gnulib could offer a working replacement for, instead of InetUtils using a hack. It looks like an OpenBSD bug that would affect other applications too. The exact compile error would help in understanding why things fail here. Could you create a small example that reproduce the problem? E.g. something like: #include <net/if.h> int main (void) { if_freenameindex ((void*)0); } or something like that? And then quote the compile error. /Simon
