From: Enrico Scholz <enrico.sch...@sigma-chemnitz.de>
The only libnsl2 function which is used by tcp-wrappers is
'yp_get_default_domain()'. When USE_GETDOMAIN is set, this is
implemented as a simple wrapper around getdomainname() so that libnsl2
is not used at all.
We added a patch which does '#include <rpcsvc/ypclnt.h>' to avoid
implicit forward declaration. By conditionalizing this, the libnsl2
dependency can be dropped completely.
