The compiler is adding an additional 16 bits of padding to make it 32 bits, which is allowed by the C standard but not desired in this case.

Even if there is a workaround for this compiler, I won’t be able to use it because it won’t be portable.

With the compiler I use, an int is 16 bits, so bitfields allways grow to the next 16 bit boundry.
