I tried to solve this problem within `configure.in'.  We cannot remove the
-liberty dependency from libserveez in general.  IRIX gets strsignal()
from -liberty inside libserveez.  Raimi: Could you test my effort ?

Basically good idea.  It is just addon.  We can implement it when time
comes by.

This much more complicated.  We would need a `portcfg-matcher' (verifies
if an ip/port combination matches another), a `array-joiner' (joins the
server array bound to an existing listener to a more general listener;
this would be necessary if we want to bind immediately and need to check
for matching portcfgs) and a connection between a server instance, a
special portcfg and the listener socket it is finally bound to (that is
because then a portcfg does not identify a listener socket uniquely).
Furthermore we need a runtime check if we accept a connection or packet on
a listener if the servers bound to it where bound by an IPADDR_ANY or a
special ip address portcfg and need to filter these.

Did I forget anything?  Seems a bit unsorted.  Did anyone understand?  I
would be happy if Raimi would reorder everything a bit...
