Setting that variable doesn't do anything because the test suite strips
out all but a few "known good" variables.

So, maybe the Guile folks can give me some portability guidance.  The
message Guile gives (when I set the above to "detailed") is this:

        Guile used to use the wrong argument order for string-delete.
        This call to string-filter had the arguments in the wrong order.
        See SRFI-13 for more details. At some point we will remove this hack.

and it's because of this code in gmk-default.scm:

   ;; Printable string (no special characters)
   ((and (string? x)
         (eq? (string-length (string-delete x char-set:printing)) 0))
    x)

It's trying to determine if the string contains any non-printable chars.


How can I write this so it will work both with older Guile 1.8 and also
with newer Guile 2.0?  Or, should I just forget about trying to work
with Guile <2.0?  Most systems I have access to still have Guile 1.8
though.
