Note that this is actually documented in the library reference, under 
`readdir'.  An excerpt:

	Return Value
	------------

	A pointer to a static buffer that is overridden with each call.

One way is to allocate the storage as needed with `malloc'.  For example:

	int max_fn = 0;
	char **fn = NULL;
	int i = 0;
	...
 	while((dir = readdir(path)))
	{
	    if (i > max_fn - 1)
	    {
		max_fn += 100;
		fn = (char **)realloc(fn, max_fn*sizeof(char *));
	    }
	    fn[i++] = strdup (dir->d_name);
	}

(`strdup' is not so portable, but you can replace it with a call to 
`malloc' and `strcpy'.)
