I will reply to that (very informative and useful) post when I feel I
have the guts to, but:

That's not possible, AFAICT.  The GNU C library has no knowledge of
zones, so it is not possible to copy the logic from unexmacosx.c to
unexelf.c just like that.

I don't know anything about unexnext.  I guess I can dig it out from
the SF repo; thanks for the pointer.

One possible way to solve the problem is to use NSZone functions
wrapped and callable from C.  But unexmacosx.c does some low-level
things which are not possible with NSZone.  So it is doubtful if this
approach would succeed at all.

It doesn't depend on him, it is the Debian Emacs maintainers' call.

Yes, I absolutely agree that it is up to us (GNUstep users) to solve
these problems.  But the CANNOT_DUMP problem is not a "simple problem"
so one should not expect that a mortal user can solve such a major
issue somehow, somewhen.
