int oneByte, oneByteASCII;
int isn't one byte, and assumes signed. Default integer in gcc is
probably 4 bytes, and short is 2. fread is putting the byte into the
top byte of your 4 byte int, which may impact the sign bit; the
effect may also depend on the endianness of the system you are
running it on.
Make oneByte and oneByteASCII char and it will do what you want.
Well, so far.
