Here's a question:

Why does the Net::DNS module, which provides only a resolver API, depend
on a Win32-related package at all?  Cygwin 1.7 provides a BSD compatible
resolver API (res_init, res_query, etc) which should be used, just like
on Linux.  Does the module erroneously treat Cygwin as Windows target?
If so, that should be fixed.
