Correct. So anythings smaller than a char is not a (full, real) dataype
in C.

Related: if you have a large number of boolean variables in your program
each will occupy 1 byte, not one bit. No big deal? Try programming on a
10F :) (Jal plug: Jal has real bit variables - they can be passed as
parameters, and they are occupy just one bit. I am not saying Jal is
better, but it proves that it is possible.)
