Hi,
I'm "upstream author", and this -lresolv thing has always been bothering
me. The problem is, If I "know what we want" or something like that,
we'll fix it in a way that is bound to break lots of other systems.
Now, I've got "debian" myself, and I'd think I'd test this myself. Or
someone slipped a patch past me that he said was good, and I forgot
to test it.
Roger.
