_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?
