This gets inserted into config.h, presumably, when trying to use
the function fails in a config script macro:

At this point, I *THINK* I can presume Guile 1.4 to be dead and gone.
Thus I *THINK* I can presume that a working libguile has scm_primitive_eval_x.
Consequently, I can simply remove this test and fix this part of the problem.
Confirmation would be appreciated.  Still, this macro ought to have worked
correctly.  Oh, wait, maybe the "#include <guile/gh.h>" messed things up?
Is that true?

So, what happened to scm_listofnull?  Is this another interface change?
