Unaligned access

[ghost]

The CAST macro is used to generate unaligned accesses. This breaks compatibility on architectures which don't support unaligned access, like ARM.

I'm looking into this issue and it seems that I would have to rewrite the CAST macro to be an inline function that uses byte loads.

[brouhaha]

I use unaligned access on ARM all the time. I guess it depends on which ARM, as there are many slightly different ARM architectures.
