 * missing_protos.h - ANSI prototypes for systems that lack complete ANSI
 *                    system header files (especially SunOS 4.x).  This file
 *                    should be included with `#include <missing_protos.h>'
 *                    from "cfht/cfht.h" so that it does not show up in
 *                    the dependencies generated by "gcc -MM".  Proper ANSI
 *                    systems should not need anything from this file anyway,
 *                    and thus will not be tempted to re-compile everything
 *                    which depends on this file every time we need to add
 *                    a new prototype for the SunOS machines.
