In case anyone is still set back by this one, I tracked
it to res_nsearch. On our AIX platforms (I was looking
at 5.2, but 4.3 looks the same) this function overwrites
a much larger area than the declared size of its input
struct __res_state. I don't know if this would be true
for everyone, or if it's a patch my hosts happen to have.
SRV lookups work better if the configure scripts don't find
res_nsearch.
Also, AIX 5 defines AI_NUMERICSERV, which has implications
for MIT's getaddrinfo wrapper.
