ioctl arguments are u_long.
Replaces `undefined' code with `defined' behavior...
gcc 2.96 performs switch cases range analysis, warns about unreachable
cases, and weeds them out.
In
switch(i) {
case VALUE:
}
VALUE is first coerced into the type of i. If i is signed, VALUE is
unsigned and exceeds i range, you lose... the result of the conversion
is undefined.
