Yes of course, I mixed up hexadecimal and decimal, it's getting late here ;).

Ok, so libc is reporting a feature the Hurd doesn't support.

I was wondering why the Qt code is using (fd != -1 || errno != EINVAL) to determine success?

Since errno is EPROTOTYPE it doesn't even try to call socket without SOCK_CLOEXEC which would be done on (errno == EINVAL).
