On native Windows platforms, there is this failure:
test-ioctl.c:38: assertion failed
FAIL: test-ioctl.exe
This patch fixes it.
2012-02-04 Bruno Haible <address@hidden>
ioctl: Fix test failure on native Windows.
* lib/ioctl.c: Include msvc-nothrow.h.
(primary_ioctl): If fd is not a valid handle, set errno to EBADF.
