Subject: [PATCH 2/2] Avoid using undocumented internals for DNS

_getshort is a reserved internal function and is deprecated per
glibc's resolv.h at least.

Use ns_get32 instead as recommended by the deprecation warning.

This also fixes an implicit function declaration warning/error with
Clang 16 / GCC 14.
