Comment(by glynn):

 Replying to [comment:1 martinl]:
 > The reason is that r.mapcalc in GRASS 6.5 doesn't use the parser, in the
 result wxGUI cannot generated dialog for this command. Try r.mapcalculator
 instead. This problem is not related to GRASS 7 (r.mapcalc uses in GRASS 7
 the parser).

 If you want "raw" r.mapcalc from the GUI, it wouldn't be particularly hard
 to add a front-end script which implements the 7.0 semantics (i.e.
 expression= and file= options). E.g. (untested, boilerplate omitted):

 {{{
 if [ -n "$GIS_OPT_EXPRESSION" ] ; then
     exec r.mapcalc "$GIS_OPT_EXPRESSION"
 elif [ -n "$GIS_OPT_FILE" ] ; then
     exec r.mapcalc < "$GIS_OPT_FILE"
 else
     echo "Either expression= or file= must be given" >&2
     exit 1
 fi
 }}}
