The "-unix <path>" argument allows s_server and s_client to use a unix
domain socket in the filesystem instead of IPv4 ("-connect", "-port",
"-accept", etc). If s_server exits gracefully, such as when "-naccept"
is used and the requested number of SSL/TLS connections have occurred,
then the domain socket file is removed. On ctrl-C, it is likely that
the stale socket file will be left over, such that s_server would
normally fail to restart with the same arguments. For this reason,
s_server also supports an "-unlink" option, which will clean up any
stale socket file before starting.
If you have any reason to want encrypted IPC within an O/S instance,
this concept might come in handy. Otherwise it just demonstrates that
there is nothing about SSL/TLS that limits it to TCP/IP in any way.
(There might also be benchmarking and profiling use in this path, as
unix domain sockets are much lower overhead than connecting over local
IP addresses).

Windows 8 SDKs complain that GetVersion() is deprecated.
We only use GetVersion like this:
(GetVersion() < 0x80000000)
which checks if the Windows version is NT based. Use a macro check_winnt()
which uses GetVersion() on older SDK versions and true otherwise.

Workaround for newer Windows headers which define EADDRINUSE but not to the
same value as WSAEADDRINUSE.

Some systems have broken IPv6 headers and/or implementations. If
OPENSSL_USE_IPV6 is set to 0 IPv6 is not used, if it is set to 1 it is used
and if undefined an attempt is made to detect at compile time by checking
if AF_INET6 is set and excluding known problem platforms.
.DLL, in particular static build. The issue has been discussed in RT#1230
and later on openssl-dev, and mutually exclusive approaches were suggested.
This completes compromise solution suggested in RT#1230.

1107. He says:
This is a followup to the NetWare patch that was applied to beta3. It
does the following:
- Fixes a problem in the CLib build with undefined symbols.
- Adds the ability to use BSD sockets as the default for the OpenSSL
socket BIO. NetWare supports 2 flavors of sockets and our Apache
developers need BSD sockets as a configurable option when building
OpenSSL. This adds that for them.
- Updates to the INSTALL.NW file to explain new options.
I have tried very hard to make sure all the changes are in NetWare
specific files or guarded carefully to make sure they only impact
NetWare builds. I have tested the Windows build to make sure it does
not break that since we have made changes to mk1mf.pl.
We are still working the gcc cross compile for NetWare issue and hope
to have a patch for that before beta 6 is released.
platforms that don't (necessarely) have it. In the case of VMS, this
means moving a couple of functions from apps/ to crypto/ and make them
general (although only used privately).
exit() in whatever way works for the intended platform, and define
OPENSSL_EXIT() to have the old meaning (the name is of course because
it's only used in the openssl program)

Here's the description, submitted by Gisle Vanem <giva@bgnett.no>:
1. sock_init() renamed to ssl_sock_init() in ./apps/s_socket.c due
to name-clash with Watt-32.
2. rand() renamed to Rand() in ./crypto/bn/divtest.c due to name-clash
with <stdlib.h>
3. Added calls to dbug_init()/sock_init() in some demo programs.
4. Changed cflags/lflags in configure. Watt-32 install root now taken
from $WATT_ROOT.
Correct misspelled VXWORKS macros.
Add VXWORKS identifying macros to e_os2.h.
Add required inclusions and mappings for VxWorks in e_os.h.
A few small modifications to make OpenSSL build and work on VxWorks.
PR: 253, except for the change that was handled in an earlier
commit, and a request for easy build of just parts of OpenSSL.
