There is nothing in C89 that allows one to define an 8-bit entity
at all portably.
In C99, there is a uint8_t but C99 defines it in such a way that
support for it is optional in an implementation. Your sample code
did not test for the appropriate macro that would indicate the
existance of uint8_t .
Thus, your code is not portable.
