+       * xreadlink.c (xreadlink): Omit size_t* arg.  All uses changed.
+       Use ssize_t, not int, to store result of readlink.
+       Check for ssize_t overflow as well as size_t overflow,
+       as POSIX says the result of readlink is implementation-defined
+       when ssize_t overflows.
+       Remove unnecessary cast to char*.
+       Use free+malloc instead of realloc, as the storage doesn't need
+       to be preserved and it's clearer and can be more efficient that way.
+       (SIZE_MAX, SSIZE_MAX): New macros, if <limits.h> doesn't declare.
+       * xreadlink.h (xreadlink): Update prototype.
