I'm getting the opinion assigning structs isn't that portable, so maybe we
should remove that code...

That link talks about how the ARM compiler *optimizes memcpy*. However in
this case it produced a memcpy out of a structure assignment. That's different
thing. However, I don't know how structure assignments are usually compiled,
but I would have thought there is a similar algorithm (like copying members
for small structs, using memcpy for large structs).
