Hm, I'm not sure why we can't just check for O_CLOEXEC itself. It's just
a #define, and always for an integer, given the prototype of open():

int foo = O_CLOEXEC;

should be sufficient, I'd think.

(... why hasn't this showed up in my mingw tests? Maybe this was added
in a recent mingw, and I'm using something later than that?)
