 *  Oooooops;  didn't handle (title) in [links]
 *  1.  ifndef bzero, define bzero(s,n) memset(s,0,n)
    2.  ifdef srandom, define SEEDRNG(x) srandom((unsigned int)x)
        eldef srand,  define SEEDRNG(x) srand((unsigned int)x)
        else  define SEEDRNG(x) (void)1
    3.  ifdef random, define COINTOSS() (random()&1)
        eldef rand, define COINTOSS() (rand()&1)
        else define COINTOSS() 1
