Solaris

It was reported by Martin Huber that under Solaris 7 following command must 
be used to compile elog:

gcc -L/usr/lib/ -ldl -lresolv -lm -ldl -lnsl -lsocket elogd.c -o elogd

It was also reported that the keep-alive mechanism is not working under some 
Solaris systems, so you need to start the elogd server with the "-k" flag to 
turn keep-alives off. 



Yep... does the job.
(even with 2.2.2 under Sol 8)
