# WARNING!!! DO NOT use older resolver libraries with untrusted data!
# WARNING!!!
#
# libresolv.a should contain the resolver library of BIND 4.8.2 or later.
# Link it in only if your default library is different.
# SCO keeps its own default resolver library inside libsocket.a
#
# lib44bsd.a contains various utility routines, and comes with BIND 4.9.*
# You may need it if you link with the 4.9.* resolver library.
#
# libnet.a contains the getnet...() getserv...() getproto...() calls.
# It is safe to leave it out and use your default library.
# With BIND 4.9.3 the getnet...() calls are in the resolver library.
#
# This program _must_ be linked with the resolver library associated
# with the header files you compiled with.
#
# GNU LibC (i.e. all variants of GNU/Linux) has a horrible mis-mash of
# half-baked header files and mangled resolver subroutines, at least
# as of 2.3.x.  E.g. there's an __RES define in <resolv.h> and a
# __NAMESER define in <arpa/nameser.h> indicating it to be BIND-8
# compatible, but there is no implementation of getipnodebyname() in
# sight.  Even worse gethostbyaddr() is totally broken and doesn't
# return multiple PTRs.  PLEASE build & link with BIND-8.4.0 or newer!
