Yes, but I still don't know how to set this in Makefile.in.

Yes, I should. Too many things on my mind.

I think that this is roughly what Waldek suggested. The environment variable
is one possibility to communicate with emacs. A different possibility would be
to modify fricas.el at configure time, but I think that this is not so good.

Would be fine for me. In particular, this would open the way to a vim mode...

OK, how about:
