Comment (by cypherpunks):

 Replying to [comment:24 catalyst]:
 > uint8_t is required by C99 to have no padding bits so the existence of
 uint8_t implies CHAR_BIT==8.  The highly improbable condition to test for
 is that CHAR_BIT==8 and uint8_t exists, but uint8_t is a type (e.g., an
 extended integer type) that's distinct from unsigned char.
 I don't think you can make that implication because (as you state) uint8_t
 is a distinct type.
