Some compilers don't allow that to happen, so you cast them to unsigned.

16 byte boundaries are needed for SSE. The instructions just before it 
add the pad, which is just once and a little bit for the entire image. 
The alignment in that part is not mandatory but helps avoid non 16 byte 
aligned pointers later on.
