+       If "xauth" is compile with "USE_SSP" set to "yes" it fails
+       mysteriously with an error message like this:
+
+       /usr/X11R7/bin/xauth:  file /foo/bar/.Xauthority does not exist
+       /usr/X11R7/bin/xauth:  unable to link authority file /foo/bar/.Xauthority, use /foo/bar/.Xauthority
+
+       The compiler seems to get confused about the two filename variables
+       used in the link(2) system call.
