Emacs allows the definition of an error message to be specified by
means of a variable called compilation-error-regexp . It's defined
in the file lisp/compile.el (which is under /usr/local/emacs in a
"standard" installation of emacs). You can set it in your .emacs file
or in the default.el file for your site via setq, e.g.

(setq compilation-error-regexp
  "\\([^ :\n]+\\(: *\\|, line \\|(\\)[0-9]+\\)\\|\\([0-9]+ *of *[^ \n]+\\)")

(This version is the one from compile.el that you need to change).

If things are really messed up, you may need to modify compile.el as well.
