Is there a way for us to get that information off the compiler? (assume 
only gcc atm)
I thought maybe compile a simple read with __attribute__((packed)) and 
another without the attribute. Then compare object files and assume that 
if they're equal, unaligned access are ok.
Is that too ugly/random/unreliable?
