My apologies; I was still using some experimental code that deactivated
the region on any C-x C-x but the first (as a side-effect to allowing a prefix
arg to toggle transient-mark-mode). Mea culpa.

I assume that you mean keyboard macro here, yes?  This usage had not 
occurred to me, as I use elisp far more often than keyboard macros, and
don't use macros for destructive things like DEL.  Perhaps this is why the 
new code works on delete-char-forward and delete-char-backward but 
explicitly not delete-char?  (I admit that I was puzzled by that choice.)
