I have encountered a bug when shifting a 'long' variable. See the sample
program below.

/*
* Test to show bug with bit-shifting a long variable.
* To show bug, compile with
*       sc -msd -3 foo.c
* To remove bug, compile with
*       sc -msd foo.c
*/
#include <stdio.h>

int main(int argc, char *argv[])
{
    unsigned a;
    long b;

    a = 29;
    b = 1L << a;
    printf("b=%08lX",b);
    return(0);
