- * Function    :  safe_strerror
- *
- * Description :  Variant of the library routine strerror() which will
- *                work on systems without the library routine, and
- *                which should never return NULL.
- *
- * Parameters  :
- *          1  :  err = the `errno' of the last operation.
- *
- * Returns     :  An "English" string of the last `errno'.  Allocated
- *                with strdup(), so caller frees.  May be NULL if the
- *                system is out of memory.
