Whether CPU architectures should trap on unaligned loads and
stores is indeed an interesting philosophical discussion.

But the C language is pretty clear on this case, in that pointer
addresses should meet the necessary alignment for the given type
behind that pointer.

So in a C language sense, the code is in fact buggy.

Alternatively, we can say that GTK+ knows better and simply
block out such dumb platforms at the top-level configure :-)
