> Some old compilers and old specification will not support bit field
> with other types except integer or unsigned integer.
> Since the next and previous items are 64b and/or 32b aligned, bit
> field with "unsigned char" type will not save any space and the
> compiler will complain.
> Changing it to "unsigned int" type bit field will solve the issue.
