Starting JIT without recompiling runs on an
error immediately, commenting that away,
another error, an so on.

To answer Tomas' question, which I thought
about also, I'm currently on GNU Emacs 24.4.1
from the distro's repo. JIT is 27.0.50.

I made a branch in the Makefile [1]

    jit-emacs=0

    ifeq ($(jit-emacs),1)
       emacs=/home/incal/emacs/emacs-feature/libjit/src/emacs
    else
       emacs=emacs
    endif

with jit-emacs as 0, not a single warning
or error. With jit-emacs as 1, well to answer
your question...

(It seems Emacs-w3m, a third party piece of
software, is the villain in the drama, and to
a lesser extent ERC. The "obsolete" stuff I can
handle myself, God willing.)
