Changes:
   07-May-1992  RNW  Program prepared for release under GNU GPL V2.
   16-Sep-1993  ABC  Changed all constants *_MAX to *_FWMAX to avoid
                     conflict with some standard UNIX constants.
   08-Aug-1995  ABC  Changed include file name from "memory.h"
                     to "fwmem.h" to avoid a clash with the C++
                     standard header file "memory.h".
