+ * Try creating a Unix-domain socket, opening it, and reading from it.
+ * The POSIX name for these is AF_LOCAL/PF_LOCAL.
+ *
+ * This is used by the Samba autoconf scripts to detect systems which
+ * don't have Unix-domain sockets, such as (probably) VMS, or systems
+ * on which they are broken under some conditions, such as RedHat 7.0
+ * (unpatched).  We can't build WinBind there at the moment.
+ *
+ * Coding standard says to always use exit() for this, not return, so
+ * we do.
