Hmm, mine says the same, but it's not entirely clear how to parse the
AND and OR conditions there. The fact that it works on Fedora suggests
to me that the "multiple vectors" case is somehow ANDed with one of the
other conditions. Anyway seems like the next step is to compare the
Fedora getopt code with mingw's ...
