It's clumsy.  Changing the sim/.../Makefile thusly activated
backtracing:

CGEN = "`if [ -f ../../guile/libguile/guile ]; then echo ../../guile/libguile/guile; else echo guile ; fi` -l $(CGENDIR)/guile.scm --debug -s"
CGENFLAGS = -v -b

The operative flags being "--debug" for guile *and* "-b" for cgen.
Perhaps we should simply activate these all the time, machines being
fast enough.


The following patch, committed, fixes cgen for frv; tested also on m32r.

      * sim.scm (-op-gen-queued-write): Add needed symbol->string.
