- * Function    :  strdup
- *
- * Description :  For some reason (which is beyond me), gcc and WIN32
- *                don't like strdup.  When a "free" is executed on a
- *                strdup'd ptr, it can at times freez up!  So I just
- *                replaced it and problem was solved.
- *
- * Parameters  :
- *          1  :  s = string to duplicate
- *
- * Returns     :  Pointer to newly malloc'ed copy of the string.

- *                which should never return NULL.

- *
- * Returns     :  An "English" string of the last `errno'.  Allocated
- *                with strdup(), so caller frees.  May be NULL if the
- *                system is out of memory.
