+       * xreadlink.c (MAXSIZE): New macro.
+       (xreadlink): Use it instead of SSIZE_MAX.  Ensure initial buffer
+       size does not exceed MAXSIZE.  Avoid cast.
+       As suggested by Mark D. Baushke in
+       <http://lists.gnu.org/archive/html/bug-gnulib/2004-11/msg00009.html>,
+       if readlink fails with buffer size just under MAXSIZE, try again
+       with MAXSIZE.
