To me, the 32-bit & 64-bit functions look like an obviously good idea. However, I cannot see that the 8-bit or 16-bit functions are needed.
Even library functions like getchar() return an int & whatever you return, it is going to be handled as an int-sized item if it goes in a register, so what's the point?
