What I was trying was get the area per raster cell (of a latlon raster). But yes, it makes sense that in in general it wouldn't be logical to have coordinates and area at the same time. I was too much focussed on my very specific case (trying an alternative way to get raster cell size of latlon grid).
Ok, now I understand your problem, but honestly, in such a situation I believe that it is better to chose a relevant projection, reproject the grid and then just use resolution^2 as cell size...
But since you already have gone down the route of calculating cell size in r.mapcalc, I guess you really wanted to do it in latlon... ;-)
