Using automated replacement with sed and editing I have now replaced all occurrences of close() with VIR_(FORCE_)CLOSE() except for one, of course. Some replacements were straight forward, others I needed to pay attention. I hope I payed attention in all the right places... Please have a look. This should have at least solved one more double-close error.
