This patch was recently committed to git master and breaks builds:

It uses event_notifier_get_fd which is only available for POSIX hosts.
W32/W64 uses event_notifier_get_handle.

Output from broken build:

   LINK  s390x-softmmu/qemu-system-s390xw.exe
hw/s390x/virtio-ccw.o: In function `virtio_ccw_set_guest2host_notifier':
hw/s390x/virtio-ccw.c:92: undefined reference to `event_notifier_get_fd'
hw/s390x/virtio-ccw.c:82: undefined reference to `event_notifier_get_fd'
