Also use -Cr. An overflow and a range check are semantically exactly 
the same (you get a value which cannot be represented by a certain 
number of bits). However, Borland first introduced range checking that 
didn't catch overflows, so when they added overflow check, they made it 
a different switch for compatibility's sake. This means that FPC is 
also stuck with two switches for catching essentially the same error...
