/* NAME:
 *      stdh.h - standard headers
 *
 * SYNOPSIS:
 *      #include "stdh.h"
 *
 * DESCRIPTION:
 *      We use this header to encapsulate all the stddef et al
 *      inclusion so that most of the source can ignore the
 *      problems that their lack might cause.
 *
 * SEE ALSO:
 *
 *
 * AMENDED:
 *      91/11/25  13:33:12  (sjg)
 *
 * RELEASED:
 *      91/11/25  13:33:17  v1.3
 *
 * SCCSID:
 *      @(#)stdh.h  1.3  91/11/25  13:33:12  (sjg)
