Introduce set_index_file() to be able to temporarily change the index file.
It should be used like this:
/* Save current index file */
old_index_file = get_index_file();
set_index_file((char *)tmp_index_file);
/* Do stuff that will use tmp_index_file as the index file */
...
/* When finished reset the index file */
set_index_file(old_index_file);
