Comment:

 does r.stats run on its own? how about `g.tempfile pid=1234`?

 note o_sum.c in gr65 calls r.stats via system() with:

 {{{
 #define STATS "r.stats"
 #define RECLASS "r.reclass"
 ...
     sprintf(command, "%s -cn input=\"%s,%s\" fs=space > %s", STATS,
 basemap,
             covermap, tempfile1);

     if (stat = system(command)) {
         unlink(tempfile1);
         G_fatal_error(_("%s: running %s command"), me, STATS);
     }
 }}}


 but before dealing with system(), a starting point might be:
 {{{

             covermap, tempfile1);

      if (stat = system(command)) {
