CINT apparently promotes case constants within
a switch statement to unsigned integers. For
example,
void stest(Int_t a)
{
switch(a) {
case 1:
printf("%d=+1\n",a);
break;
case -1:
printf("%d=-1\n",a);
break;
default:
printf("Unknown %d\n",a);
break;
}
}
root [9] stest(1)
1=+1
root [10] stest(-1)
Unknown -1
root [11] stest(0)
0=-1
As far as I know, C/C++ allow case constants
to be any integer, not just unsigned integers.
Or, at least, CINT ought not to covert
case -1: ---> case 0:
but intead flag this as an error.
