How true :-)
My exercise had been using cygwin (and thus the dl* functions) and would
have ported to *nix likely, had I had a *nix box handy... :-/
I don't know if I'd recommend Cygwin to everyone, since it (at least for
me) makes one think that they're operating in *nix, but with all the
fallacies of Windows hidden just out of sight. (As I experienced with file
execution and permission here.)
