Ok, I reply to myself -- also to ask a subsequent question...

Ok, the trouble comes from the fact that Unix.open_connection uses
in_channel_of_descr of which the manual says

  in_channel_of_descr  does not work on sockets under Windows 95, 98, ME;
                       works fine under NT and 2000

Well, I tried the program under Win 2000 Professional and got the same
error...  Anyway, it would be nice that (1) open_connection be
mentionend in the manual as not working under win 9* or, even much
better, to make that (2) Unix.open_connection actually works under
win32!  IMHO it is quite unfortunate that in_channel_of_descr does not
work under windows for sockets since it basically forces the
programmer to reimplement input/output functions for these.

Is the current situation made for efficiency reasons (it is costly for
in/out channels to carry their type with them) or is there a deeper
problem with Win$ platforms?
