_res is (well, was, after your last commits) declared in res_init.c:
[...]
/*
* Resolver state default settings.
*/
struct __res_state _res
# if defined(__BIND_RES_TEXT)
= { RES_TIMEOUT, } /* Motorola, et al. */
# endif
;
#ifdef INET6
struct __res_state_ext _res_ext;
#endif /* INET6 */
[...]

Yes, but of what OBOS networking kit part?
ifconfig? ping? libnet.so itself?

That make sense.

Which is strange.
Do you install the so-called fixed ld linker, or are you still using
the BeOS R5 one?
