No, it's not the 'current implementation', its the way the C and C++ standards
say this has to happen.  When arithmetic operators are applied to sub-int sized
operands they are first converted to int (or unsigned int if they can't be
represented in int -- which is only the case when you have a machine where
sizeof(unsigned short) == sizeof(unsigned int), or something similar).
