By "old" you mean the one in Emacs < 22, right?

IIUC the way it works is that you have one regexp that matches the
message with the file name (can have nil for its LINE/COLUMN info), and
then have another that matches the messages without file name (this one
will have nil for the FILE part but presumably non-nil for the LINE and
maybe COLUMN part).

If you look at the way compile-internal was implemented in Emacs-22 and
23 (quoted below), you see you should be able to just use your
compilation-file-regexp-alist entries directly in
compilation-error-regexp-alist (assuming that worked in Emacs-23).
