Switch statement: extra out-of-bounds code emitted

Given a switch statement of the form:
unsigned char i;
switch ( i ) {
case 0: funct0(); break;
case 1: funct1(); break;
...
case 255: funct255(); break;
}
bounds checking the index variable is unnecessary.
I did a little research and this was suggested in 1989
and again in 1997, not exactly qualifying as an FAQ.
Can someone comment on this?
