Re: "Recent" changes to compilation-mode?

[Richard Stallman]

    Well, my usual experience of being able to browse compilation errors
    just stopped working, and I had to dig through the docs for
    compilation-next-error to find out that the whole world was different.
    It would have been nicer if the system had detected that I was using
    the old variables and given me a warning about the change and pointed
    me at the new docs, or better yet had done the translation
    automatically for me.

I agree that something like this would be good.
I think something like this could be implemented as a superficial
change that would not alter the existing code, and thus would be safe.

Unfortunately I don't have time to do it myself.  Could someone please
study this and implement such a transition aid?
