 This would be wrong, especially on arches where u_md is nonempty because
 the kernel will supply user structs with u_md in them.
 
 The problem is moot in -current since u_md went away.  struct mdproc has
 also become nonempty on i386's, but there is now an empty struct mdthread
 to break compiling with -ansi at least in the kernel (-pedantic is also
 needed for breakage; -ansi alone works and this is tested a lot since the
 kernel is always compiled with it).
