Ken,

  Thanks for your response to my problem compiling socket programs on 5.0.
I got another response to change my compile command in the posix shell that
fixed the problem.  I was using:

c89 -o w2unix -lsocket wtouserv.c

Changed it to:

c89 -o w2unix wtouserv.c -lsocket

and no more unresolved externals.  I've tried to find some documented reason
for this behavior, but haven't yet.

Thanks, Bob Rose
