The test syntax looked complicated, and I assumed that the documentation was terrible, like wine's, but it's actually pretty good, so I'll give it a go. I think the order is not really surprising though. It is run from right to left, but basically it means that right options override left options, which is how most of them work, e.g. -W and -Wno work based on the rightmost toggle, same with -f and -fno, etc.
