+This is a synonym for @code{AF_LOCAL}.  Although @code{AF_LOCAL} is
+mandated by POSIX.1g, @code{AF_UNIX} is portable to more systems.
+@code{AF_UNIX} was the traditional name stemming from BSD, so even most
+POSIX systems support it.  It is also the name of choice in the Unix98
+specification. (The same is true for @code{PF_UNIX}
+vs. @code{PF_LOCAL}).
