For guile-2.0, I eventually settled on 
 
scm_call_1 (scm_c_public_ref ("system repl repl", "start-repl"),
   scm_from_locale_symbol ("scheme"));
 
This trick I learned from this e-mail from Tristan
 
http://lists.gnu.org/archive/html/bug-guile/2011-10/msg00040.html
 
And with that, ",q" returns control to the calling C function.
 
(I'm in a push to release a new rev of everything I've ever done in 2012.
I'd like to get to the point where all my guile-1.8 using progs only use
functions documented in the 1.8 manual and ditto for guile-2.0)
 
Thanks,
 
Mike
