 * Compile-time flags:
 *
 * UXPR - this enables driverkit-style xpr functionality. The module which
 *	  implements this, machdep/nrw/ddm.c, is compiled into the kernel 
 *	  when this flag is true. Currently this is true in all nrw builds.
 * DDM_DEBUG - enables actual uxpr() macros. Currrently this is true only
 *	  in nrw DEBUG builds. 
 *
 * RELEASE kernels compile in ddm.c to allow loadable servers to use the 
 *	  uxpr mechanism.
