Thanks for your reply, but I'm not looking for a workaround, and
certainly would not like to use those (mangling resolv.conf just for
c-ares? what about the other software that doesn't use c-ares?)

Again that is a workaround. Not useful in my case since I want a
solution not only for me, but for anyone who uses the application I
distribute.

You are correct, now that I test again, I see it works on Linux but not
on Windows, so its probably the lack of resolv.conf that makes things
not work (under Cygwin). If I add resolv.conf to Cygwin, it works!

Also on Windows but with a native program that uses c-ares (built with
MinGW), it doesn't work. So it must be something missing (BTW I have
ISC BIND running on Windows, with a split view, everything works fine --
I can 'ping' with a relative name (w.r.n.), I can ssh w.r.n. before I
added resolv.conf (and after)).

Thanks.
