I can't believe (but may be wrong, of course) that gnupg2 tries to
access /etc/resolv.conf by itself.  I would rather guess that gnupg2
is linked against one or more libs provided by the bind package,
and thus uses the resolver from the bind package.  However, Cygwin
provides its own resolver entry points, and those don't need
/etc/resolv.conf, because they utilize the OS resolver.

Is there a build option to avoid building against the bind lib?
Alternatively it might be possible to inject an autoconf variable
from cygport...?
