Yes, lots of objections :) My changes are much much smaller, you are 
comparing too many versions together, with many changes by Ludovic 
perhaps.. I did the changes to the butlast version, already present in 
non-fsf and in the past pre-releases. My changes are restriceted to one 
method and the goal is to use res_ninit() which is thread-safe instead 
of res_init(). There is the possibility to enable it for one or the 
other platform. For me it works on Linux and NetBSD if yo udo not 
require password authentication (see numerous threads on the gnustep ML 
where I called for help). I Am pretty sure I dod no harm on OpenBSD 
either. At least, no harm compared to the previous version of the file.

Check:
http://svn.gna.org/viewcvs/gnustep-nonfsf/frameworks/pantomime/Framework/Pantomime/CWDNSManager.m?r1=10&r2=66

and play with  #define HAS_RES_NINIT 1

As you see, it is enabled only for NetBSD currently. The goal is to test 
it on other platforms too, since it would be the way to go. As-is my 
change should not affect other platforms.
