Patch from Dario Alcocer <alcocer@connectnet.com> and Ralf Corsepius
<corsepiu@faw.uni-ulm.de> which attempts to detect when the UNIX port
is being configured on a system without System V IPC support. This
is an optional component on both FreeBSD and Linux systems. Most
Linux 2.x kernels ship with it enabled but it is still a real risk.
This test may have undesirable side-effects on some hosts. We will
address those conflicts as they arise.
