I thought only the embedded versions didn't implement the NUL device.
The Media Center Edition is nothing more than Pro edition with the
domain join functionality removed and enhanced multimedia software which
makes it ideal for a Media Center PC.  I will look into it.  My laptop
runs MCE but I havn't had a chance to get Cygwin on it.  A test case
will be useful to me and also the packages installed will also be useful
so I can try to replicate the environment.
