Although shutdown.exe works fine on NT (XP at least), it's not possible to
shutdown a system to a power off state with shutdown.exe on Win9x
(Win98SE tested).

It's been my experience (on Win98SE anyway) that it's directly related
to the ShutdownEx() API. Despite what the API docs say, EWX_POWEROFF
actually performs a log off, while EWX_SHUTDOWN performs a power off
shutdown, on Win9x. This behavour seems to hold true even in a non
cygwin application.

The following patch to shutdown-1.3-1 makes 'shutdown -s' work as
expected (power off, instead of log off) on Win9x, tested on Win98SE.

Mark.
