The problem is that you have no guarantee how the compiler packs the  
bits inside your nibble data type. E.g., the bits may be ordered  
little or big endian (note that this about bit-endianess, not byte  
endianess; although the used bit-edianess may also differ depending on  
whether you are on a little/big byte-endian system -- which it already  
does, currently).
