Apparently you didn't notice that we switched from Mingw.org headers
to Mingw-w64 headers to support the 64 bit Cygwin effort.

With Mingw-w64 headers, don't use the DDK headers in conjunction with
user space applications.  These headers are not appropriate for that and
the fact that we could use the Mingw.org equivalents was just a nice
effect, but nothing you ever should have relied upon (just as in Cygwin,
we originally did the same, but we changed it).

The (unfortunately incomplete) replacement for the user space is the
deprecated ntdef.h, or the more adequate winternl.h.  Patches to extend
winternl.h are welcome on the mingw-w64-public ML.
