Please help us test the behavior of different Unices

Hi again,

some additional Information from other sources[1]:

NetBSD 6, 7 and current are all the same on multiple architectures:
System: NetBSD:6.1_STABLE:NetBSD 6.1_STABLE (LUNA-$Revision: 6.2 $) #0: Mon 
Jan  9 21:39:01 UTC 2017  john at chi.zia.io:/usr/release/obj-vax/sys/arch/vax/
compile/LUNA
sizeof addr.sun_path: 104
Running test with strlen (cwd): 22, name: '/tmp/test-unix-sockets/socket'
  getsockname returned '/tmp/test-unix-sockets/socket', addrlen: 106
Running test with strlen (cwd): 22, name: 'socket'
  getsockname returned 'socket', addrlen: 106
Running test with strlen (cwd): 126, name: 'socket'
  getsockname returned 'socket', addrlen: 106
Running test with strlen (cwd): 1062, name: 'socket'
  getsockname returned 'socket', addrlen: 106

Mac OS X (PowerPC, amd64) are the same:
System: Darwin:9.8.0:Darwin Kernel Version 9.8.0: Wed Jul 15 16:57:01 PDT 
2009; root:xnu-1228.15.4~1/RELEASE_PPC
sizeof addr.sun_path: 104
Running test with strlen (cwd): 22, name: '/tmp/test-unix-sockets/socket'
  getsockname returned '/tmp/test-unix-sockets/socket', addrlen: 106
Running test with strlen (cwd): 22, name: 'socket'
  getsockname returned 'socket', addrlen: 106
Running test with strlen (cwd): 126, name: 'socket'
  getsockname returned 'socket', addrlen: 106
Running test with strlen (cwd): 1062, name: 'socket'
  getsockname returned 'socket', addrlen: 106

On IBM Power8 running Ubuntu GNU/Linux (ppc64le):
System: Linux:4.4.0-64-generic:#85-Ubuntu SMP Mon Feb 20 17:05:51 UTC 2017
sizeof addr.sun_path: 108
Running test with strlen (cwd): 22, name: '/tmp/test-unix-sockets/socket'
  getsockname returned '/tmp/test-unix-sockets/socket', addrlen: 32
Running test with strlen (cwd): 22, name: 'socket'
  getsockname returned 'socket', addrlen: 9
Running test with strlen (cwd): 130, name: 'socket'
  getsockname returned 'socket', addrlen: 9
Running test with strlen (cwd): 1102, name: 'socket'
  getsockname returned 'socket', addrlen: 9

Kind regards,
Jochen
