I'm not sure if I ever answered this.

Yes Squid does have an implementation of a resolver. Its recently had
file lookup capability added to it. It's not 1-1 to resolver (3), but
it's not far off.

Is it or could it become a separate lib?

Short answer yes and yes.

Background:
squid started its life doing dns lookups via a farm of helper processs.
The core interface within squid stayed the same when the new rfc1035
code was directly implemented. the only change was that the helper farm
went away and calls to the new library were used. I don't know how
closely the library corresponds to resolve(3).

Look at
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/squid/squid/lib/rfc1035.c
?rev=1.1.1.2.2.1.6.5&content-type=text/vnd.viewcvs-markup for the
source.

It's pure GPL, not LPGL.

Hi, I've read about resolver lib for cygwin. kde on cygwin needs a resolver
lib too. Does anyone know the state of this integration into cygwin ?

One year ago I've downloaded a bindlib for native win32, which comes from
the University of California. I'm not an export in dns programming, but it
seems to contains a complete resolver lib. I'm unable to compile it for
cygwin, but perhaps someone else is able to do, for that if someone like to
get the source,
please send me a mail to Ralf.Habacker@saght.tessag.com.

Best regards
