Openssh 3.8p1-2 is using autoconf 2.52 and has the problem, krb5
1.3.2 is even using 2.59.

krb5 for instance returns this:
checking for res_search... no
checking for res_search in -lresolv... no
configure: error: Cannot find resolver support routine res_search in -lresolv.
make: *** [configure-stamp] Error 1

The test program looks like:
| char res_search ();
| int
| main ()
| {
| res_search ();
|   ;
|   return 0;
| }

Without resolv.h it will not find __res_search, with resolv.h it
will fail to compile because of "too few arguments to function".
