/* WHAT'S HERE:  a bunch of stuff typically needed for my code
                 - but you might not need it all
 Includes (& what they are needed for
   * <stdio.h>  (printf, FILE, stderr, fopen, (size_t))
   * <stdlib.h> or equivalent (malloc, atof, labs, NULL, size_t)
   * <fcntl.h>  (O_RDONLY etc)
   * <string.h> (strcmp, rindex, strrchr)
 Defines
   * READMODE, WRITEMODE for fopen of binary files
   * MYFLTARG for type of floats in prototypes
 Macros
   * MIN, MAX (arguments evaluated twice)
   * PARG -- for optional argument prototypes : void fn PARG((type arg));
 PARG is pretty important, but you could include it explicitly
 in any stand-alone header you wanted to build.
