When you run Emacs in a terminal, do you get any sensible font locking
e.g. of C files?  If not, it may be an issue more general than ESS.
if you do, what do you see?

e.g. try the following snippet of C code.

  mm = 4 * n;			/* Number of repeats */
  mm *= 10;			/* if starting from Poisson distribution. */
  for (i=0; i<= mm; i++) {
    id = (int)(n*UNIF);	/* pick one point at random. */
    /*Rprintf("select new point for unit %d\n", id);*/
    xpts[id] = xpts[0]; ypts[id] = ypts[0];

For what its worth, I see different font locking in an X11 Emacs
window compared to when I view the same code within a Gnome Terminal.
(e.g. on the above code, although "/*" and "*/" are highlighted in
red, the text "Number of repeats" is not highlighted in red.

I'm not sure if this is a bug, or intentional...
