Thank you.  It looks good, and I *will* be trying it.  But my main point 
was that it needs to be in the documentation.  (And notice that you 
still didn't say what libraries need to be linked, or that none do.)

I understand that most of the documentation is not specific to operating 
systems.  And that's good.  But where you *need* information about the 
operating system, the information needs to be there, just like the 
compiler options which differ between Linux and MSWind are documented 
differently.

And yes, what you displayed (i.e., the code) should be identical between 
OSes.  But that's only the majority of the information needed.  I think 
I could figure it out by checking what worked the last time I did it, 
even though that was with D1, but it really should be in the 
documentation.  So, for that matter, should the code.  If I knew where 
to post the request, I'd post it there, but as it is I'm just hoping 
that an appropriate person will read this and act on it.
