* Why "EMACS=24.4.91.2 (term:0.96)" in term-exec-1?

Hi all,

I've been putting up with this misfeature for quite some time.
Basically, I can't just type `make test' into ansi-term for ERT testing.
I have to either re-export the EMACS variable (by hand, since I can't
just nail it down in the Makefile), or call `make test' from outside
Emacs.

Turns out, the reason is in `term-exec-1', accompanied by this comment:

    ;; We are going to get rid of the binding for EMACS,
    ;; probably in Emacs 23, because it breaks
    ;; `./configure' of some packages that expect it to
    ;; say where to find EMACS.
    (format "EMACS=%s (term:%s)" emacs-version term-protocol-version)

So I have two questions: what was the reason for setting this variable,
and can we remove it?

regards,
Oleh

I think these discussions will answer your first question:

Thanks, Eli. Is it time to get rid of the binding for EMACS, just like
the comment says?

My current solution is to use "emacs" instead of "EMACS" as a variable
in all Makefiles. I'd prefer to use the caps.

I think so, yes.  The same applies to the "EMACS=t" binding used in
shell.el (as discussed recently).

The latest version of Bash still looks at EMACS and not INSIDE_EMACS, so 
there may be a compatibility problem if Emacs stops setting EMACS now.  
Today I filed a bug report with the Bash maintainers here:

If we wait for them to move before we do, then nothing's ever going
to move.  Instead, we just have to wait until they *can* move.
And nowadays they can move (because INSIDE_EMACS should be available in
"all" the Emacsen that people are still using), so we can force the move.
