hstrerror is part of libresolv and any system which has a libresolv too
old to have hstrerror will likely have many many other resolver bugs too.
Similarly the functions inet_net_ntop() and inet_net_pton() will be
missing (they were introduced prior to BIND-4.9.5-P1 for goodness sake!!).
The best solution for any application that needs DNS is to simply
require that the user upgrade their resolver first (eg. install
BIND-8.2.2-P5 or whatever's newest). Anything else is shooting yourself
in the ankles.....
As for how autoconf can ensure it's found the newest resolver library
available on a system, well that's probably best left for a '--with'
parameter if the default search path doesn't find a viable -lresolv.
Note too that recent BIND-8's resolver library is called -lbind.

SunOS-4 didn't IIRC, which suggests 4.2BSD didn't. 4.3BSD definitely
did though.
If you're linking against BIND-8's resolver you get it for free though! ;-)

everything back to, and including, SysIII has getopt(). I don't think
4.2BSD had it, but it's in 4.3BSD for sure. AT&T PD'd the code for one
of their versions in 1985.
