No patch is needed for the file in question.
windows/property.c needs a simple patch though.

Yes. I've noticed that and I have fixed a few of them as well.
However I'm not optimistic on fixing them all on the short term.
The problem is not the number of them, the problem is that
some of the warnings like the Global* can't be fixing in
the .c files. It involves changing the .h files and that
generated even more warnings. :-(

I will investigate furher, but as I said, I'm not optimistic.
