FSF says the following, but apparently the HAVE_RES_INIT stuff takes
care of it properly?
/* #if 0 This isn't right.  Apparently some sites do have -lresolv
	 but don't use that.  On those systems, the code below loses.
	 There's no way to win automatically unless someone
	 figures out a way of determining automatically which way is right
	 on any given system.  */

/* Some systems do not run the Network Information Service, but have
   modified the shared C library to include resolver support without
   also changing the C archive library (/usr/lib/libc.a).  If we
   detect the presence of libresolv.a, use -lresolv to supplement libc.a.

   We used to have #ifdef HAVE_GETHOSTNAME is to prevent configure from
   setting libsrc_libs to -lresolv in lib-src/Makefile.  But nowadays
   configure is smarter about computing libsrc_libs, and would not
   be fooled.  Anyway, why not use -lresolv in lib-src?  */
