Hi Steven,

Hey, that's some great debugging!!  With your change above, I was able
to verify that an executable dumped on 10.2.2 before the security update
can be run on one after the update was applied.  Please install the
change when you can.

Somewhat related, while working in unexmacosx.c, I notice the function
build_region_list.  This function is left over from earlier versions of
the file and is unnecessary since dumping is now based on the emacs_zone
regions.  I'll remove it at some point.

Andrew.
