On x86 and x86_64, this warning is never emitted because it is perfectly
fine to do unaligned access. On sparc, such accesses are not supported
by the hardware and will generate a SIGBUS. This must be caught by a
trap handler, and the unaligned access performed there, slowly, using
byte by byte access.
However, making this a Werror is annoying because it will trigger
everytime one casts a byte pointer to something larger, even when
alignment is actually preserved. So, removing all such warnings would be
nearly impossible (for example, just for the mergesort function, there
is a whole GSoC project for it at FreeBSD).
Keep it as a warning for now. The warning can be silenced by using
BytePointer, if desired. We should also investigate where the SIGBUS
trap is triggered a lot and consider improving the alignment of data
where possible.
