This is used iff Guile antedates 1.6.  I guess that can be junked now?

This is used iff Guile antedates 1.8.  To my knowledge, there is no
other way to set the line number, prior to 1.8.

Because the strings are extracted from large text files and it is important
that the error message reveal the correct file and line number.  It is
precisely because of the issues with cruft like using internal Guile
structures that I'd be so extremely happy to (finally) see a a proper export of:
  scm_c_eval_string_from_file_line(SCM string, SCM file, SCM line)
Then for GUILE_VERSION >= 109000 I could just #define my variation
to the Proper Call.  :)

Thank you!  Regards, Bruce
