Peter,

So I used to be able to tell whether Perl is threaded by version as I
still can with Activeperl that I use on Windows for my Tk menus.

Now that we have recent Perl versions which are non threaded how can I
tell if my version is or is not threaded? I'm sure it's a really dumb
question.

Frank.
