I know of at least one architecture where sizeof(char)==sizeof(int) == 32 bits.
(Although the only compiler for it that I'm aware of is freestanding.)
All that's required is that sizeof(char) be no bigger than sizeof(int).
This won't break the getchar() interface, I believe, because getchar() doesn't
necessarily have to return all values of type char. It has to return all 
characters in the machine's basic character set, plus EOF. So on this machine
the bit patterns for char values -1 through 255 would all be distinct.
