Yes, but can it be done in a way that the back compatible bits are
kept separate from the core?  A while ago you mentioned something like
_GNU_SOURCE, which seems exactly right to me.

For example, an application would just say

#define _GUILE_SOURCE 1.6
#include <libguile.h>

And a 1.7.x/1.8.x libguile.h would have something at the end like

#if _GUILE_SOURCE = 1.6
#include <guile/compat-1.6.h>

Similarly, any back compatibility object code would ideally be in; although I'm not sure how to make the linking
in of the extra library as automatic as possible for the application

It's possible that I may have described what you are already doing,
then :-)
