Are you even certain that it is a byte operation???  All I see is an increment
of an object in memory pointed to by the variable "x".

Now, had we been told what the declaration of "x" is, the question would be
more meaningful, but if it's something less than word sized, then the byte
manipulation instructions would work just fine.

I don't see a problem, and think that this is a pretty weak straw man.
