OK, at least we have some consistency.

This could be the problem, but I'd be skeptical, as you had success
earlier.  The accept error message reports the C strerror string,
which was "No such file ..."  I think this is the first of the
following errors, whatever mingw's numbering system could be:

ERRORS
       EAGAIN or EWOULDBLOCK
              The  socket  is  marked non-blocking and no connec-
              tions are present to be accepted.

       EBADF  The descriptor is invalid.

       ENOTSOCK
              The descriptor references a file, not a socket.

       EOPNOTSUPP
              The referenced socket is not of type SOCK_STREAM.

       EFAULT The addr parameter is not in a writable part of the
              user address space.

       EPERM  Firewall rules forbid connection.

       ENOBUFS, ENOMEM
              Not  enough free memory.  This often means that the
              memory allocation is limited by the  socket  buffer
              limits, not by the system memory.



Sounds to me that #'listen is returning T before a connection is
present, i.e. the select code we've added there might not be working
for you.  Just an idea.

Might want to start with telnet for simplicity.  Might want to break
in gdb at the select in #'listen, and see if it is working, and if so,
whether it is accept that fails for some other reason.

Take care,
