Sourceforge's CVS server seems to be acting up at the moment, and the
couple-of-months-old version of paserve that I have didn't define the
class ACL-COMPAT.SOCKET::SERVER-SOCKET.  From what I can tell from the
Web CVS interface, the PORT slot of an ACL-COMPAT.SOCKET::SERVER-SOCKET
has a :TYPE of FIXNUM, and the backtrace you sent indicates that it's
being passed explicitly as NIL.

The function MAKE-SOCKET (in acl-compat/mcl/acl-socket-openmcl.lisp)
accepts a :PORT argument (defaulting its value to NIL) and tries to
make an instance of a SERVER-SOCKET with this :PORT.  NET.ASERVE:START
doesn't pass a :PORT argument to MAKE-SOCKET (it passes :LOCAL-PORT);
so MAKE-SOCKET tries to pass :PORT NIL (as we see.)  Signaling a
type error at this point is probably better than failing in some more
obscure way a little later.

Someone seems to have added chunking support for openmcl recently.
The CVS checkin comment notes that they accepted a speed loss in
doing so; in my model of things, that seems to defeat one of the
main purposes of using chunked transfer encoding.

Some of these changes seem to have been made just before the holidays;
that's certainly my excuse for bugs in 0.14-031220 ...
