I afraid I don't really follow you. Are every other 8 bits of the 16 bit char 
unused? Wouldn't it be possible to use a 16 bit type instead? I was thinking 
of using u16_t:s for most of the stuff and shift the 8 bits around.

The CHAR_BIT #define seems to be the right way to go.

About the bit fields - they are gone in the latest code. They were just too 
much hassle with too little gain.
