 * This doesn't hurt because you can't include both of these

 *	<sys/old_procfs.h>
 * unless _STRUCTURED_PROC is first defined to be 1.
 * (Including <procfs.h> defines it to be 1.)

 * However, the latest version of lint goes overboard in hunting
 * down and reporting differences in functions and data of the

 * is no real problem.  To mitigate this, we redefine the old procfs
 * names when performing lint.
