There is no such an animal as "minimalist" DNS lookup routine.
Your best bet is to pick bind-8.2.* sources, and dig out
the libbind or libresolv (which name it happens to be)
sources which contain gethostbyname() implementation.
You can't remove very much out of that code.

Usually that DNS server referral is stored into /etc/resolv.conf
file, and thus you can do away without using codes to scan that
configuration file by supplying the server address as a parameter.
