First pass over the code I disabled the compilation flag and then
did quick substitution for the easier functions. I commented out the
WSASendDisconnect calls so I could see what tests would fail if
the function was just removed. I have a replacement now that uses
"shutdown(fd,SD_SEND)", but I still have a few more test failures to

I updated the error message text for "getaddrinfo".

I'll post a revised webrev after the 4 jshell errors are corrected.
