Thanks to the people that responded, especially Steve Alexander @ Lachman.

There are two ways to fix it, I'll present Steve's, since it's more elgant
than mine.  In the routine makeconnection() in daemon.c, the socket is
open & connected, then two fdopen's are made on the same socket.

System V has a bug in stdio, so this won't work right.  The two solutions
are either (a) open it once for reads & writes, and then do rewinds
between reads & writes (ugly), or Steve's solution, just dup() the socket.
(I didn't think that would work, so I never tried it).

Old code:
	*outfile = fdopen(s, "w");
	*infile = fdopen(s, "r");

New code:
	*outfile = fdopen(dup(s), "w");
	*infile = fdopen(s, "r");

I've tried it out, and it seems to run like a champ (so far :-) ).

Hope this helps someone else.  The rest of the 5.61 conversion is
trivial.  If anyone wants diffs off the 5.61 distribution for System5
w/Berkeley networking (at least Unisoft's),  drop me a note.
