Huh?  The only place where it is called seems to be in:

      (with-current-buffer outbuf
        (compilation-mode name-of-mode)
        ;; In what way is it non-ergonomic ?  -stef
        ;; (toggle-read-only 1) ;;; Non-ergonomic.
        (set (make-local-variable 'compilation-parse-errors-function) parser)
        (set (make-local-variable 'compilation-error-message) error-message)
        (set (make-local-variable 'compilation-error-regexp-alist)
        (set (make-local-variable 'compilation-enter-directory-regexp-alist)
        (set (make-local-variable 'compilation-leave-directory-regexp-alist)
        (set (make-local-variable 'compilation-file-regexp-alist)
        (set (make-local-variable 'compilation-nomessage-regexp-alist)
        (set (make-local-variable 'compilation-arguments)
             (list command error-message
                   name-of-mode parser
                   error-regexp-alist name-function
                   enter-regexp-alist leave-regexp-alist
                   file-regexp-alist nomessage-regexp-alist))
        ;; This proves a good idea if the buffer's going to scroll
        ;; with lazy-lock on.
        (set (make-local-variable 'lazy-lock-defer-on-scrolling) t)
        (setq default-directory thisdir
              compilation-directory-stack (list default-directory))
        (set-window-start outwin (point-min))
        (or (eq outwin (selected-window))
            (set-window-point outwin (point-min)))
        (compilation-set-window-height outwin)
        (if compilation-process-setup-function
            (funcall compilation-process-setup-function))

I don't see anything between the with-current-buffer and the call
to compilation-process-setup-function which could change current-buffer.
