Actually, if I understand this right, it is doing this properly.  The 
unsigned int only requires one byte of memory when using bitfields.
If you used:
struct A {unsigned int x, y, z;};
struct B {unsigned int x, y, z;};
Then yes, the compiler is wrong.
Think of it this way:  here is your "A" structure (memory wise - unsigned 
t)
FEDC BA98 7654 3210
.... ...Z ZZZZ  YYX
(I may be wrong - X may be at 'F', but I am not sure.)
You see, it still only uses one byte of memory.
