Well, why am I able to use them already?  From bindings.el (1.145):

(define-key esc-map "gn" 'next-error)
(define-key esc-map "g\M-n" 'next-error)
(define-key ctl-x-map "`" 'next-error)

Hm, I'll have to check how something like this can be done in Emacs 21
and XEmacs.

I just looked into compile.el for that and it seems that this is only
there for compatibility reasons.  Again, I'd need to have a more
thorough look to understand what is involved here.

If only key bindings are changed it is not very invasive.

First, we currently have a button for jumping to the next error which
holds an exclamation mark.  (Of course, this might change.)  Second,
an exclamation mark is connotated with attention which is something an
error should really get. (c;
