Hi Kevin,
It turns out that in all places where I was using scm_makstr(), I was
also using SCM_CHARS to access the string memory and then fill it in.
It *must* be safe to do because I don't call any scheme functions before
I am done scribbling in the memory. Anyway, to be safer, I have removed
all use of SCM_CHARS and that made scm_makstr unusable so I am using a
new approach. I do not use scm_makstr anymore.
Since it takes a *LOT* of work to get autogen-5.7.2 to run under
Guile 1.7.x, I don't think it worth the bother to try to use that
as an example. If someone were to say, "I will work on the issue",
then I'll hack my autogen-5.8preXXX to use that function once again.
And fail. Otherwise, lets forget it.
Thanks for your help. Regards, Bruce

Me, either. I did a bunch of grepping into the 1.4.1 and 1.6.7 source,
but nothing jumped out as the way it was accomplished. Black magic? :)
In the end, I've altered my test thus:
cat > ${testname}.samp6 <<EOF
${testname}.tpl6:7:4: In expression (stumble-over-unbound-variable):
${testname}.tpl6:7:4: Unbound variable: stumble-over-unbound-variable
Scheme evaluation error. AutoGen ABEND-ing in template
error.tpl6 on line 3
EOF
if test ${GUILE_VERSION} -gt 107000
then
echo "WARNING: Guile 1.7.x cannot display error line numbers" >&2
exec 3> ${testname}.samp6-tmp
echo 'ERROR: Unbound variable: stumble-over-unbound-variable' >&3
sed 1,2d ${testname}.samp6 >&3
exec 3>&-
mv -f ${testname}.samp6-tmp ${testname}.samp6
fi
