I have little experience with DBs and SQL magic, sorry.
(I didn't add the v.reclass stuff)

I assume this comes from here:

   table=`v.db.connect $GIS_OPT_INPUT -g | grep -w $GIS_OPT_LAYER | awk '{print $2}'`
   if [ -z "$table" ] ; then
      g.message -e 'There is no table connected to this map!'
      cleanup
      exit 1
   fi

possibles:
1) is "grep -w" portable?
2) Is "grep -w 1" slightly vague? Perhaps: grep "^$GIS_OPT_LAYER "
3) test for [ $? -ne 0 ] instead of [ -z $table" ], or && ?
???
