I thought the code above was illegal at least in 2.059.
You can write the code as
case 0: case 1: case 2,3:
and be ok.
I get an error
unless I use goto case:
void main()
{
int i;
int j;
switch (i) {
case 0,1:
goto case; // goto, embraced by D :)
case 2,3:
j = 42;
break;
default:
j = 43;
}
}

The error only shows up if -w is used.
