Ah!  You mean, make merely does a literal text comparison of the
"filename" one gives it ("progmodes/cc-engine.elc") with the target
($(lisp)/progmodes/cc-engine.elc, which expands to
"/home/acm/emacs/emacs-22/lisp/progmodes/cc-engine.elc").  They don't
match.

What's the best way of handling this?

Anyway, when I do

   % make -nf CC-Makefile.mk /home/acm/emacs/emacs-22/lisp/progmodes/cc-engine.elc

, make replies with this:

   EMACSLOADPATH=/home/acm/emacs/emacs-22/lisp ../src/emacs -batch --no-site-file --multibyte -f batch-byte-compile /home/acm/emacs/emacs-22/lisp/progmodes/cc-defs.el
   EMACSLOADPATH=/home/acm/emacs/emacs-22/lisp ../src/emacs -batch --no-site-file --multibyte -f batch-byte-compile /home/acm/emacs/emacs-22/lisp/progmodes/cc-langs.el
   EMACSLOADPATH=/home/acm/emacs/emacs-22/lisp ../src/emacs -batch --no-site-file --multibyte -f batch-byte-compile /home/acm/emacs/emacs-22/lisp/progmodes/cc-engine.el

, which is what I want.

Many thanks!
