Might be overkill but:

        #define XXX(index) do { \
                if (moff & (0xffUL << ((index) * 8))) {
                        out[outpos++] = moff >> ((index) * 8);
                        i |= 1 << (index);
                }
        } while (0)

        XXX(0);
        XXX(1);
        XXX(2);
        XXX(3);

        #undef XXX

would do the trick.  Pick a proper name for XXX of course.
