the additional libraries for heroes3 are taken from the official
slackware-8.1 package "glibc-2.2.5-i386-4.tgz", which is still 
available on most slackware-mirrors.

these libraries will make heroes3 run independent from the system's
glibc and therefore make networked games possible again.

for further information see bug #71044.

have fun,
