Hello!
Our computer has a /360 compatibe processor, which generates
exception when changing the sign of value X'80000000'.
To avoid this I offer next the modification in this function:
old:
while (i != 0) {
i ^= (i & ((unsigned) (- (int) i)));
++count;
}
new:
while (i != 0) {
i = (i & (i-1));
++count;
}
