Dan, you repeatedly compare the PowerPC and Alpha architectures
although they are different architectures and have different behaviors
with respect to unaligned accesses.  You earlier proposals try to make
PowerPC as strict as the earliest Alpha architecture and some proposals
broke ABI compatibility.  Both of these proposals are incorrect.

	This came about because an application data structure was designed
exceptionally poorly.  I think that it would be much more effective to fix
the source of the problem and not the symptom.
