Make ngIRCd compile and run on NeXTSTEP 3.3 and OPENSTEP 4.2

by Steven D. Blackford <kb7sqi@aol.com>:

"I wanted to let you know that I've done a quick port of ngircd-0.12.0 for
NEXTSTEP3.3/OPENSTEP4.2. There wasn't a lot of changes required to get it
to compile clean, but I did make the necessary changes so that I didn't
have to use -posix flag. The NeXT has a pretty buggy POSIX implementation
so I always try to work around it. :-)
Anway, here's the changes required to get it to compile."
