I should tell here what I wrote to Gisle privately: Gnulib attempts to
hide the Windows socket-related idiosyncrasies by returning a file
descriptor instead of the 'native' handle, and Gnulib's 'select'
expects such file descriptors.  However, converting a handle into a
file descriptor and vise versa involves using 2 simple functions, so I
hope a more elegant solution should be possible.

Admittedly, Gisle already built Wget with libcares, while I didn't, so
his inputs and opinions carry more weight than mine...
