That's sort of the point isn't it? Does it fix the problem? Don't know. It
certainly will quash the warning, but does it quash a valid warning as well?
Don't know. 

However if you work with properly align pointers all the way through, with the
warnings on, you have a fairly strong proof that it is correct (w.r.t. alignment)

The correct answer is to do as I said, work with (_Obj *)'s instead of (char *)
and the problem will go away.

The solution in the repository now has the virtue of being there, and I no
longer use sparc's anyway, so I'll not be coding it myself. When a 64 bit
machine lands on my desk in a year or three, I'll worry (intensely) about it
again...
